About Pro-Pharmaceuticals, Inc.

We are a development-stage company engaged in the discovery and development of therapeutics that target Galectin receptors that we believe enhance existing cancer treatments and could also be used in the treatment of tissue fibrosis, particularly liver fibrosis, inflammatory diseases, and enhancement of tumor vaccines. All of our products are presently in development, including pre-clinical and clinical trials.

Since our inception on July 10, 2000, our primary focus has been the development of a new generation of anti-cancer treatments using polysaccharide polymers that are aimed at increasing survival and improving the quality of life for cancer patients. Our lead product candidate, DAVANAT^®, is a patented new chemical entity that we believe, when administered in combination with chemotherapy, biologics and vaccines, increases efficacy while reducing adverse side effects of the chemotherapy. The Company holds composition of matter and method of use patents on DAVANAT^®, which were invented by the founders, without any license or royalty encumbrances.

In 2002, the Food and Drug Administration (“FDA”) granted us an Investigational New Drug application (“IND”), for use of DAVANAT^® in combination with 5-fluorouracil (“5-FU”), to treat late-stage cancer patients with solid tumors. 5-FU is one of the most widely used chemotherapies for treatment of various types of cancer, including colorectal, breast, head and neck, and other gastrointestinal cancers. In September 2008, we submitted a clinical and pre-clinical package to the FDA in support of our DAVANAT^® New Drug Application (“NDA”). Following a meeting in December 2008, the FDA advised us that we would be required to conduct a Phase III trial to demonstrate superiority to the best standard of care for late stage colorectal cancer patients.

On December 17, 2010, we met with the FDA to present our Phase III clinical development program for DAVANAT^®. Agreement was reached on the design of pivotal, randomized, controlled, and blinded Phase III clinical trials of DAVANAT^® co-administered with standard chemotherapy for second line treatment of patients with metastatic colorectal cancer.

On March 9th, 2011 we announced that our Board of Directors named Peter G. Traber, M.D., President and Chief Executive Officer, effective March 17, 2011. Dr. Traber was named Interim Chief Medical Officer in June 2010 and appointed to the Board of Directors in February 2009. Dr. Traber succeeds Theodore D. Zucconi, Ph.D., who continues as a member of the Board of Directors. Dr. Zucconi also will direct Company operations with a focus on approvals and expansion of the Latin American business and manufacturing.

We were incorporated under Nevada law on January 26, 2001 and in May of that year acquired a Massachusetts corporation (organized on July 10, 2000) engaged in the business we now undertake. We have a wholly-owned Delaware subsidiary that we formed in 2003 to hold our cash and cash equivalents. We also have a wholly-owned Nevada subsidiary that we formed in August 2010 for the development of our technology in cardiovascular treatments.

Principal Executive Offices

Our principal executive offices are located at 7 Wells Avenue, Newton, Massachusetts 02459. Our telephone number is (617) 559-0033, fax number is (617) 928-3450 and our website address is www.pro-pharmaceuticals.com.

The Offering

Securities Offered

4,797,500 shares of our common stock offered by selling stockholders

Use of Proceeds

We will not receive any proceeds from the sale of shares by the selling stockholders. To the extent that the warrants are exercised by the selling stockholders for cash, rather than by cashless exercise, we will receive proceeds constituting the exercise price of such warrants. Any such proceeds received by us through warrant exercises will be used for working capital.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference contain, in addition to historical information, forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. These statements relate to future events or our future financial performance and can be identified by the use of forward-looking terminology such as “may,” “could,” “expect,” “anticipate,” “estimate,” “continue” or other similar words. These forward-looking statements are based on management’s current expectations and are subject to a number of factors and uncertainties which could cause actual results to differ materially from those described in these statements. We caution investors that actual results or business conditions may differ materially from those projected or suggested in forward-looking statements as a result of various factors including, but not limited to, those described in, or incorporated by reference into, the Risk Factors section of this prospectus. We cannot assure you that we have identified all the factors that create uncertainties. Readers should not place undue reliance on forward-looking statements. We undertake no obligation to publicly release the result of any revision of these forward-looking statements to reflect events or circumstances after the date they are made or to reflect the occurrence of unanticipated events.

RISK FACTORS

An investment in our common stock involves a high degree of risk. You should carefully consider the risks described below and the other information before deciding to invest in our common stock. The risks described below are not the only ones facing our company. Additional risks not presently known to us or that we currently consider immaterial may also adversely affect our business. We have attempted to identify below the major factors that could cause differences between actual and planned or expected results, but we cannot assure you that we have identified all of those factors.

If any of the following risks actually happen, our business, financial condition and operating results could be materially adversely affected. In this case, the trading price of our common stock could decline, and you could lose all or part of your investment.

Risks Related to Our Company

We have incurred net losses to date and must raise additional capital by the end of the second quarter of 2012 in order to continue to operate.

We have incurred net losses in each year of operation since our inception in July 2000. Our accumulated deficit as of December 31, 2010 was $56.4 million and our cumulative net loss applicable to common stockholders as of December 31, 2010 was $56.7 million. Based on $5.9 million of unrestricted cash as of December 31, 2010 and $2.6 million received subsequent to year end through March 15, 2011, we believe that we have sufficient cash to meet our financial and operating obligations through 2012. We will require more cash to fund our operations and believe that we will be able to obtain additional financing. However, there can be no assurance that we will be successful in obtaining such new financing or, if available, that such financing will be obtainable on terms favorable to us. We have taken steps to reduce our administrative and clinical spending; however, we must raise additional cash by the end of the fourth quarter of 2012, or we may not be able to continue operations and may be forced to seek bankruptcy protection.

We may raise capital through public or private equity financings, partnerships, debt financings, bank borrowings, or other sources. Additional funding may not be available on favorable terms or at all. If adequate funds are not otherwise available, we may need to significantly curtail operations. To obtain additional funding, we may need to enter into arrangements that require us to relinquish rights to certain technologies, products and/or potential markets. To the extent that additional capital is raised through the sale of equity, or securities convertible into equity, our equity holders may experience dilution of their proportionate ownership of the company.

We are a development stage company and have not yet generated any revenue.

We are a development stage company and have not generated any revenues to date. We granted PROCAPS, S.A. exclusive rights to market and sell DAVANAT^® to treat cancer patients in Colombia, South America, which we refer to as the PROCAPS Channel. In addition, there is no assurance that we will obtain FDA approval of DAVANAT^® or any other of our products in development and, even if we do so, that we will generate revenue sufficient to become profitable. Our failure to generate revenue and profit would likely lead to loss of your investment.

We have one drug candidate in clinical trials and results are uncertain.

DAVANAT^®, our lead product candidate, is in human clinical trials. Clinical trials are expensive, time-consuming and may not be successful. They involve the testing of potential therapeutic agents, or effective treatments, in humans, typically in three phases, to determine the safety and efficacy of the product candidates necessary for an approved drug. Many products in human clinical trials fail to demonstrate the desired safety and efficacy characteristics. Even though DAVANAT^® progressed successfully through Phase I and Phase II human trials, it may fail in Phase III trials or in later stages of development. We will engage others to conduct our clinical trials, including clinical research organizations and, possibly, government-sponsored agencies. These trials may not start or be completed as we forecast, or may not achieve desired results.

We may be unable to commercialize our product candidates.

Even if DAVANAT^® and other anticipated product candidates achieve positive results in clinical trials, we may be unable to commercialize them. Although we anticipate receipt of regulatory approvals in connection with the PROCAPS Channel, there is no assurance that such approvals will be obtained. Our general inability to commercialize our products would substantially impair the viability of the Company.

Performance milestones may not occur as contemplated by the agreement with PROCAPS S.A.

As our arrangement with PROCAPS is a collaboration, and because collaborations take place over time, milestone and performance risks are inherent and so performance milestones may not occur as contemplated by our agreement.

There are risks associated with our reliance on third parties to design trial protocols, arrange for and monitor the clinical trials, and collect and analyze data.

As we develop products eligible for clinical trials, including DAVANAT^®, we will contract with independent parties to assist us in the design of the trial protocols, arrange for and monitor the clinical trials, collect data and analyze data. In addition, certain clinical trials for our products may be conducted by government-sponsored agencies and will be dependent on governmental participation and funding. Our dependence on independent parties and clinical sites involves risks including reduced control over the timing and other aspects of our clinical trials.

There are risks associated with our reliance on third parties for manufacturing, marketing, sales, managed care and distribution infrastructure and channels.

We do not have, and do not now intend to develop, facilities for the manufacture of any of our products for clinical or commercial production. At this time, we are not a party to any long-term agreement with any of our suppliers, and accordingly, we have our products manufactured on a purchase-order basis from one of two primary suppliers. We are developing relationships with manufacturers and will enter into collaborative arrangements with licensees or have others manufacture our products on a contract basis. We expect to depend on such collaborators to supply us with products manufactured in compliance with standards imposed by the FDA and foreign regulators.

We have limited experience in marketing, sales or distribution, and we do not intend to develop a sales and marketing infrastructure to commercialize our pharmaceutical products. If we develop commercial products, we will need to rely on licensees, collaborators, joint venture partners or independent distributors to market and sell those products. Thus, we expect that we will be required to enter into agreements with commercial partners to engage in sales, marketing and distribution efforts around our products in development. We may be unable to establish or maintain third-party relationships on a commercially reasonable basis, if at all. In addition, these third parties may have similar or more established relationships with our competitors. If we do not enter into relationships with third parties for the sales and marketing of our proposed products, we will need to develop our own sales and marketing capabilities.

Even if engaged, these distributors may:

•

fail to satisfy financial or contractual obligations to us;

•

fail to adequately market our products;

•

cease operations with little or no notice to us; or

•

offer, design, manufacture or promote competing formulations or products.

If we fail to develop sales, managed care, marketing and distribution channels, we would experience delays in generating sales and incur increased costs, which would harm our financial results.

Our lack of operating experience may cause us difficulty in managing our growth.

We have limited experience in manufacturing or procuring products in commercial quantities, conducting other later-stage phases of the regulatory approval process, selling pharmaceutical products, or negotiating, establishing and maintaining strategic relationships. Although we have engaged a number of consultants to assist us, any additional growth may require us to expand our management, operational and financial systems and controls. If we are unable to do so, our business and financial condition would be materially harmed. If rapid growth occurs, it may strain our managerial, operational and financial resources.

We are exposed to product liability, pre-clinical and clinical liability risks which could place a financial burden upon us, should we be sued, because we do not currently have product liability insurance above and beyond our general insurance coverage.

Our business exposes us to potential product liability and other liability risks that are inherent in the testing, manufacturing and marketing of pharmaceutical formulations and products. Claims may be asserted against us. In addition, the use in our clinical trials of pharmaceutical formulations and products that our potential collaborators may develop and the subsequent sale of these formulations or products by us or our potential collaborators may cause us to bear a portion of or all product liability risks. A successful liability claim or series of claims brought against us could have a material adverse effect on our business, financial condition and results of operations.

Because we do not currently have any FDA-approved products or formulations, we do not currently have any product liability insurance covering commercialized products. We may not be able to obtain or maintain adequate product liability insurance on acceptable terms, if at all, or such insurance may not provide adequate coverage against our potential liabilities. Furthermore, our current and potential partners with whom we have collaborative agreements or our future licensees may not be willing to indemnify us against these types of liabilities and may not themselves be sufficiently insured or have sufficient liquidity to satisfy any product liability claims. Claims or losses in excess of any product liability insurance coverage that may be obtained by us could have a material adverse effect on our business, financial condition and results of operations.

If users of our proposed products are unable to obtain adequate reimbursement from third-party payers, market acceptance of our proposed products may be limited and we may not achieve revenues.

The continuing efforts of governments, insurance companies, health maintenance organizations and other payers of healthcare costs to contain or reduce costs of health care may affect our future revenues and profitability, and the future revenues and profitability of our potential customers, suppliers and collaborative partners and the availability of capital. In other words, our ability to commercialize our proposed products will depend in large part on the extent to which appropriate reimbursement levels for the cost of our proposed formulations, products and related treatments are obtained by the health care providers of these products and treatments. At this time we cannot predict the precise impact of the Patient Protection and Affordable Care Act of 2010, as amended by the Health Care and Education Affordability Act of 2010, the comprehensive health care reform legislation passed by Congress in March 2010. It is possible that the adoption of this legislation could harm our business, financial condition and results of operations.

We depend on key individuals to develop our products and pursue collaborations.

We are highly dependent on Anatole Klyosov, Ph.D., D.Sc. and Peter G. Traber, M.D. Dr. Klyosov is our Chief Scientist and has scientific technical or other business expertise and experience that is critical to our success. Dr. Traber is our Chief Medical Officer who, among other things, leads our FDA Phase III colorectal cancer trial for DAVANAT^® as well as our overall FDA approval process. Effective March 17, 2011 Dr. Traber will become our Chief Executive Officer as well as our Chief Medical Officer. The loss of Dr. Klyosov or Dr. Traber, or failure to attract or retain other key personnel, could prevent us from pursuing collaborations or developing our products and core technologies.

We are involved in litigation with Summer Street Research Partners.

On January 30, 2008, Custom Equity Research, Incorporated (d/b/a Summer Street Research Partners), or Summer Street, filed a lawsuit against us, alleging claims for breach of contract, declaratory judgment and unjust enrichment arising out of an engagement letter under which Summer Street agreed to provide institutional investment placement services. Discovery is currently underway. A trial date has been set for November 8, 2011. We believe the lawsuit is without merit and intends to contest it vigorously.

We received a letter dated January 12, 2011 from Maxim Group, or Maxim, which has acted as our placement agent. The letter advises that Maxim has been named as a respondent in a FINRA arbitration matter commenced by Summer Street arising out of the Company’s termination of its relationship with Summer Street and its engagement of Maxim as its placement agent. Our placement agent agreement with Maxim contains an indemnification provision that requires us to indemnify Maxim in connection with FINRA arbitration. We believe the claims asserted by Summer Street in the arbitration are without merit.

Risks Related to the Drug Development Industry

We will need regulatory approvals to commercialize our products.

We are required to obtain approval (i) from the FDA in order to sell our products in the U.S. and (ii) from foreign regulatory authorities in order to sell our products in other countries. The FDA’s review and approval process is lengthy, expensive and uncertain. Extensive pre-clinical and clinical data and supporting information must be submitted to the FDA for each indication for each product candidate in order to secure FDA approval. Before receiving FDA clearance to market our proposed products, we will have to demonstrate that our products are safe on the patient population and effective for the diseases that are to be treated. Clinical trials, manufacturing and marketing of drugs are subject to the rigorous testing and approval process of the FDA and equivalent foreign regulatory authorities. The Federal Food, Drug and Cosmetic Act and other federal, state and foreign statutes and regulations govern and influence the testing, manufacture, labeling, advertising, distribution and promotion of drugs and medical devices. As a result, regulatory approvals can take a number of years or

longer to accomplish and require the expenditure of substantial financial, managerial and other resources. The FDA could reject an application or require us to conduct additional clinical or other studies as part of the regulatory review process. Delays in obtaining or failure to obtain FDA approvals would delay or prevent the commercialization of our product candidates, which would prevent, defer or decrease our receipt of revenues. In addition, if we receive initial regulatory approval, our product candidates will be subject to extensive and rigorous ongoing domestic and foreign government regulation.

Data obtained from clinical trials are susceptible to varying interpretations, which could delay, limit or prevent regulatory clearances.

Data already obtained, or in the future obtained, from pre-clinical studies and clinical trials do not necessarily predict the results that will be obtained from later pre-clinical studies and clinical trials. Moreover, pre-clinical and clinical data is susceptible to varying interpretations, which could delay, limit or prevent regulatory approval. A number of companies in the pharmaceutical industry have suffered significant setbacks in advanced clinical trials, even after promising results in earlier trials. The failure to adequately demonstrate the safety and effectiveness of a proposed formulation or product under development could delay or prevent regulatory clearance of the potential drug. The resulting delays to commercialization could materially harm our business. Our clinical trials may not demonstrate sufficient levels of safety and efficacy necessary to obtain the requisite regulatory approvals for our drugs, and thus our proposed drugs may not be approved for marketing.

Our competitive position depends on protection of our intellectual property.

Development and protection of our intellectual property are critical to our business. All of our intellectual property, patented or otherwise, has been invented and/or developed by employees of the Company. If we do not adequately protect our intellectual property, competitors may be able to practice our technologies. Our success depends in part on our ability to obtain patent protection for our products or processes in the U.S. and other countries, protect trade secrets, and prevent others from infringing on our proprietary rights.

Since patent applications in the U.S. are maintained in secrecy for at least portions of their pendency periods (published on U.S. patent issuance or, if earlier, 18 months from earliest filing date for most applications) and since other publication of discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain that we are the first to make the inventions to be covered by our patent applications. The patent position of biopharmaceutical firms generally is highly uncertain and involves complex legal and factual questions. The U.S. Patent and Trademark Office has not established a consistent policy regarding the breadth of claims that it will allow in biotechnology patents.

Some or all of our patent applications may not issue as patents, or the claims of any issued patents may not afford meaningful protection for our technologies or products. In addition, patents issued to us or our licensors may be challenged and subsequently narrowed, invalidated or circumvented. Patent litigation is widespread in the biotechnology industry and could harm our business. Litigation might be necessary to protect our patent position or to determine the scope and validity of third-party proprietary rights, and we may not have the required resources to pursue such litigation or to protect our patent rights.

Although we require our scientific and technical employees and consultants to enter into broad assignment of inventions agreements, and all of our employees, consultants and corporate partners with access to proprietary information to enter into confidentiality agreements, these agreements may not be honored.

Products we develop could be subject to infringement claims asserted by others.

We cannot assure that products based on our patents or intellectual property will not be challenged by a third party claiming infringement of its proprietary rights. If we were not able to successfully defend our patents or other intellectual property, we may have to pay substantial damages, possibly including treble damages, for past infringement.

We face intense competition in the biotechnology and pharmaceutical industries.

The biotechnology and pharmaceutical industries are intensely competitive. We face direct competition from U.S. and foreign companies focusing on pharmaceutical products, which are rapidly evolving. Our competitors include major multinational pharmaceutical and chemical companies, specialized biotechnology firms and universities and other research institutions. Many of these competitors have greater financial and other resources, larger research and development staffs and more effective marketing and manufacturing organizations, than we do. In addition, academic and government institutions are increasingly likely to enter into exclusive licensing agreements with commercial enterprises, including our competitors, to market commercial products based on technology developed at such institutions. Our competitors may succeed in developing or licensing technologies and products that are more effective, or succeed in obtaining FDA or other regulatory approvals for product candidates before we do. Acquisitions of, or investments in, competing pharmaceutical or biotechnology companies by large corporations could increase such competitors’ financial, marketing, manufacturing and other resources.

The market for our proposed products is rapidly changing and competitive, and new drugs and new treatments which may be developed by others could impair our ability to maintain and grow our business and remain competitive.

The pharmaceutical and biotechnology industries are subject to rapid and substantial technological change. Developments by others may render our proposed products noncompetitive or obsolete, or we may be unable to keep pace with technological developments or other market factors. Technological competition from pharmaceutical and biotechnology companies, universities, governmental entities and others diversifying into the field is intense and is expected to increase.

As a pre-revenue company engaged in the development of drug technologies, our resources are limited and we may experience technical challenges inherent in such technologies. Competitors have developed or are in the process of developing technologies that are, or in the future may be, the basis for competition. Some of these technologies may have an entirely different approach or means of accomplishing similar therapeutic effects compared to our proposed products. Our competitors may develop drugs that are safer, more effective or less costly than our proposed products and, therefore, present a serious competitive threat to us.

The potential widespread acceptance of therapies that are alternatives to ours may limit market acceptance of our proposed products, even if commercialized. Many of our targeted diseases and conditions can also be treated by other medication. These treatments may be widely accepted in medical communities and have a longer history of use. The established use of these competitive drugs may limit the potential for our technologies, formulations and products to receive widespread acceptance if commercialized.

Risks Related to Our Common Stock

Stock prices for pharmaceutical and biotechnology companies are volatile.

The market price for securities of pharmaceutical and biotechnology companies historically has been highly volatile, and the market from time to time has experienced significant price and volume fluctuations that are unrelated to the operating performance of such companies. Fluctuations in the trading price or liquidity of our common stock may adversely affect, among other things, the interest in our stock by purchasers on the open market and, generally, our ability to raise capital.

Our Board of Directors has the power to designate, without shareholder approval, a series of preferred stock the shares of which could be senior to the common stock and be entitled to conversion or voting rights that adversely affect the holders of our common stock.

Our Articles of Incorporation authorizes issuance of capital stock including 20,000,000 undesignated shares, and empowers our Board of Directors to prescribe by resolution and without shareholder approval a class or series of undesignated shares, including the number of shares in the class or series and the voting powers,

designations, rights, preferences, restrictions and the relative rights in each such class or series. Accordingly, we may authorize the issuance of additional shares or series of preferred stock that would rank senior to the shares of common stock as to dividend rights or rights upon our liquidation, winding-up, or dissolution.

We could issue additional common stock, which might dilute the book value of our common stock.

Our Board of Directors has authority, without action or vote of our shareholders, to issue all or a part of our authorized but unissued shares. Such stock issuances could be made at a price that reflects a discount or a premium from the then-current trading price of our common stock. In addition, in order to raise capital, we may need to issue securities that are convertible into or exchangeable for a significant amount of our common stock. These issuances would dilute the percentage ownership interest, which would have the effect of reducing your influence on matters on which our shareholders vote, and might dilute the book value of our common stock. You may incur additional dilution if holders of stock options, whether currently outstanding or subsequently granted, exercise their options, or if warrant holders exercise their warrants to purchase shares of our common stock.

One investor, by virtue of ownership of our securities and related rights, may be able to control the Company.

The 10X Fund, L.P., or 10X Fund, owns all of our issued and outstanding Series B-1 Convertible Preferred Stock and Series B-2 Convertible Preferred Stock, collectively the Series B Preferred Stock, which are convertible into 12 million shares of our common stock. The 10X Fund owns related warrants exercisable to purchase an aggregate of 36 million shares of our common stock. We have issued approximately 2.1 million shares of our common stock as dividends on the Series B Preferred Stock. In addition, James C. Czirr, a general partner of the 10X Fund and Executive Chairman of our Board of Directors, owns or controls approximately 5 million shares of our common stock. As of December 31, 2010, on a fully diluted basis, assuming conversion of all Series B Preferred Stock and exercise of all the related warrants, the 10X Fund would own approximately 44.8% of our then outstanding shares of common stock, which together with Mr. Czirr’s shares of our common stock, would constitute approximately 49.2% of the then outstanding shares. As holder of Series B Preferred Stock, the 10X Fund is entitled to elect two directors in a separate class vote, nominate three directors for election by all shares entitled to vote, and provide or withhold consent to a range of fundamental corporate action we may wish to undertake, such as recapitalization, sale of the company, and other matters. Such concentration of stock ownership and related rights could have the effect of delaying, deterring or preventing corporate events that our other security holders may desire or consider beneficial to the company.

As a “thinly-traded” stock, large sales can place downward pressure on our stock price.

Our common stock, despite certain increases of trading volume from time to time, experiences periods when it could be considered “thinly-traded.” Finance transactions resulting in a large amount of newly issued shares that become readily tradable, or other events that cause current shareholders to sell shares, could place downward pressure on the trading price of our stock. In addition, the lack of a robust resale market may require a shareholder who desires to sell a large number of shares of common stock to sell the shares in increments over time to mitigate any adverse impact of the sales on the market price of our stock.

USE OF PROCEEDS

We will not receive any proceeds from the sale of the shares by the selling stockholders. To the extent that the warrants are exercised by the selling stockholders for cash, rather than by cashless exercise, we will receive proceeds constituting the exercise price of such warrants. Any such proceeds received by us through warrant exercises will be used for working capital.

SELLING STOCKHOLDERS

In February 2008, we completed a private placement of 1,742,500 units to investors, with each unit consisting of (1) one share of our Series A 12% Convertible Preferred Stock, which is convertible into one share of common stock, (2) a five-year warrant to purchase one share of common stock at an exercise price of $1.50, and (3) a five-year warrant to purchase one share of common stock at an exercise price of $2.00.

This prospectus covers the sale by the selling stockholders from time to time of:

•

1,562,500 shares of common stock issuable upon the conversion of shares of our Series A 12% Convertible Preferred Stock sold in the February 2008 private placement; and

•

3,235,000 shares of common stock issuable upon the exercise of the warrants sold in the February 2008 private placement.

We issued the securities to the selling stockholders without registration under the Securities Act of 1933 (the “Securities Act”) in reliance upon the exemption provided by Section 4(2) of the Securities Act for transactions not involving a public offering. Prior to issuance, each selling stockholder represented to us that it was an accredited investor, as defined in Rule 501 of Regulation D under the Securities Act, and that it was acquiring the securities for investment purposes only and not with a view to, or sale in connection with, any distribution thereof.

The term “selling stockholder” includes (i) each person and entity that is identified in the table below (as such table may be amended from time to time by means of an amendment to the registration statement of which this prospectus forms a part) and (ii) any transferee, donee, pledgee or other successor of any person or entity named in the table that acquires any of the shares of common stock covered by this prospectus in a transaction exempt from the registration requirements of the Securities Act and that is identified in a supplement or amendment to this prospectus.

We have listed below:

•

the name of each selling stockholder;

•

the number of shares of common stock known to be beneficially owned by the selling stockholder based on beneficial ownership information available to us as of the date of this prospectus;

•

the maximum number of shares of common stock being offered by each of them in this offering; and

•

the number of shares of common stock to be owned by the selling stockholder after this offering (assuming sale of such maximum number of shares) and the percentage of the class which such number constitutes (if one percent or more).

The footnotes to the table identify each selling stockholder that is a registered broker-dealer or an affiliate of a registered broker-dealer.

Except as otherwise noted below, during the last three years, no selling stockholder has been an officer, director or affiliate of our company, nor has any selling stockholder had any material relationship with our company or affiliates during that period. Each selling stockholder represented at the closing of the private

placement that it did not have any contract, undertaking, agreement or arrangement with any person to sell, transfer, pledge, hypothecate, grant any option to purchase or otherwise dispose of any of the securities. Based on information provided to us by the selling stockholders, the selling stockholders purchased the securities in the ordinary course of business.

The shares of common stock being offered hereby are being registered to permit public secondary trading, and the selling stockholders are under no obligation to sell all or any portion of their shares included in this prospectus. The information contained in the following table is derived from information provided to us by selling stockholders, our books and records, as well as from our transfer agent. Where we were unable to obtain information from a selling stockholder with respect to the total number of shares beneficially owned by such holder, we have included only the shares underlying warrants held by such holder.

Unless otherwise indicated, each person has sole investment and voting power with respect to the shares indicated. For purposes of this table, a person or group of persons is deemed to have “beneficial ownership” of any shares as of a given date which such person has the right to acquire within 60 days after such date.

We do not know when or in what amounts a selling stockholder may offer shares for sale. The selling stockholders may not sell any or all of the shares offered by this prospectus. Because the selling stockholders may offer some or all of the shares pursuant to this prospectus, and because there are currently no agreements, arrangements or understandings with respect to any of the shares, we cannot estimate the number of the shares that will be held by the selling stockholders after completion of the offering. However, for purposes of this table, we have assumed that, after completion of the offering, none of the shares covered by this prospectus will be held by the selling stockholders. The numbers of shares shown under the column “Common Stock Owned Upon Completion of this Offering” reflect the assumption solely for purpose of this table that such shares are still owned upon completion of the offering, which assumption is not intended to override the selling stockholder table in, as applicable, any other prospectus covering the resale of any other of our securities by the selling stockholders.

PLAN OF DISTRIBUTION

Each selling stockholder and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of his, her or its shares on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. A selling stockholder may use any one or more of the following methods when selling shares:

•

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

•

block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

•

an exchange distribution in accordance with the rules of the applicable exchange;

•

privately negotiated transactions;

•

settlement of short sales entered into after the effective date of the registration statement of which this prospectus is a part;

•

broker-dealers may agree with the selling stockholders to sell a specified number of shares at a stipulated price per share;

•

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

•

a combination of any of these methods of sale; or

•

any other method permitted pursuant to applicable law.

The selling stockholders may also sell shares under Rule 144 under the Securities Act rather than under this prospectus.

Broker-dealers engaged by the selling stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA/NASD Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with FINRA/NASD IM-2440.

In connection with the sale of shares, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the shares in the course of hedging the positions they assume. The selling stockholders may also sell shares short and deliver these shares to close out their short positions, or loan or pledge shares to broker-dealers that in turn may sell these shares. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to that broker-dealer or other financial institution of shares offered by this prospectus, which shares that broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect that transaction).

The selling stockholders and any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with those sales. In that event, any commissions received by those broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each selling stockholder has informed us that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the shares. In no event shall any broker-dealer receive fees, commissions and markups which, in the aggregate, would exceed eight percent (8%) of the gross proceeds of any sale.

We are required to pay certain fees and expenses incurred by us incident to the registration of the shares. We have agreed to indemnify the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

Because selling stockholders may be deemed to be “underwriters” within the meaning of the Securities Act, they will be subject to the prospectus delivery requirements of the Securities Act including Rule 172 thereunder. In addition, any securities covered by this prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than under this prospectus. There is no underwriter or coordinating broker acting in connection with the proposed sale of the resale shares by the selling stockholders.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the shares may be resold by the selling stockholders without registration and without regard to any volume limitations by reason of Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the shares have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The shares will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), any person engaged in the distribution of the shares may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations there under, including Regulation M, which may limit the timing of purchases and sales of the shares by the selling stockholders or any other person. We will make copies of this prospectus available to the selling stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

BUSINESS

In 2002, the Food and Drug Administration, or FDA, granted us an Investigational New Drug application, or IND, for use of DAVANAT^® in combination with 5-fluorouracil, or 5-FU, to treat late-stage cancer patients with solid tumors. 5-FU is one of the most widely used chemotherapies for treatment of various types of cancer, including colorectal, breast, head and neck, and other gastrointestinal cancers. In September 2008, we submitted a clinical and pre-clinical package to the FDA in support of our DAVANAT^® New Drug Application, or NDA. Following a meeting in December 2008, the FDA advised us that we would be required to conduct a Phase III trial to demonstrate superiority to the best standard of care for late stage colorectal cancer patients.

Our Strengths and Strategies

Focus on novel therapeutic opportunities that target Galectin receptors. We believe our company is a pioneer focused on development of therapeutics that target Galectin proteins to treat cancer, enhance tumor vaccines, and treat inflammatory and fibrogenic diseases. We believe this offers a largely untapped area for treatment of disease.

Leverage extensive scientific expertise. Our scientists have substantial expertise, developed over decades, in the area of carbohydrates that target Galectin receptors. Our team has conducted research in therapeutic application of carbohydrate-based therapeutics for more than 20 years. Dr. Klyosov, who headed the Carbohydrate Research Laboratory at the USSR Academy of Sciences and was a visiting biochemistry professor at Harvard Medical School, holds more than 20 patents. We believe that his expertise, supplemented by members of our Scientific and Medical Advisory Boards, provides us with a substantial advantage in this relatively new area of drug development.

Completion of development milestones toward commercialization of DAVANAT^® and 5-FU combination cancer therapy. We have completed important milestones in the development of DAVANAT^® in combination with 5-FU to treat late-stage cancer patients with solid tumors. These include our submission of the Drug Master File, or DMF, to the FDA in May 2008, which we believe demonstrates our ability to produce commercial quantities of pharmaceutical-grade DAVANAT^® under manufacturing standards known as cGMP (“current Good Manufacturing Process”); our submission in September 2008 of a clinical and pre-clinical package to the FDA in support of our DAVANAT^® NDA; and our December 2008 and December 2010 pre-NDA meetings with the FDA which provided guidance as to certain components of Phase III trials of DAVANAT^® that would be needed for an NDA demonstrating superiority to the best standard of care for colorectal patients.

Apply our technology to broad range of applications. Our research indicates that DAVANAT^® has the potential for broad application. Following development of DAVANAT^® in combination with chemotherapies and vaccines, we plan to also combine it with drugs to extend its use to treat other serious diseases, such as liver fibrosis. Pre-clinical studies indicate that DAVANAT^®, and other proprietary therapeutics we have in development, may have application for advanced treatment of inflammatory disorders and organ fibrosis, particularly liver fibrosis.

Product Development

We are initially developing a pipeline of compounds that may be combined with chemotherapies, such as 5-FU, as well as vaccines so as to improve the clinical benefit to cancer patients. Based on research, we believe DAVANAT^®, when combined with chemotherapies may increase the clinical benefit to cancer patients by extending survival and increasing quality of life through reduction of chemotherapy associated side effects. Our lead product candidate, DAVANAT^®, is a patented new chemical entity that the FDA agreed on a clinical development plan for us to begin the Phase III development program following submission and approval of the final protocol.

To date, DAVANAT^® has been administered to approximately 100 cancer patients in Phase I and II trials, as well as compassionate use INDs. Data from a Phase II trial for late-stage metastatic colorectal cancer patients showed DAVANAT^® when combined with 5-FU extended median survival to 6.7 months with significantly reduced side effects, as compared to 4.6 months for best standard of care as determined by the patient’s physician. Importantly, patients had a marked reduction in the incidence and severity of 5-FU related side effects. The reduction in side effects can improve the patients quality of life.

In addition, results of pre-clinical studies we have conducted in mice show that more 5-FU accumulates in the tumor when co-administered with DAVANAT^® than when 5-FU is administered alone in the mice. Our pre-clinical and clinical trial data also show that DAVANAT^® is safe and non-toxic. Our initial NDA for DAVANAT^® will seek FDA approval for co-administration of DAVANAT^® with 5-FU for intravenous injection for the treatment of metastatic colorectal cancer.

DAVANAT^®

DAVANAT^®, our lead product candidate in development, is a proprietary polysaccharide polymer comprised of mannose and galactose that is derived from plant sources and has a precisely defined chemical structure. More specifically, it is galactomannan which is isolated from seeds of guar and subjected to a controlled partial chemical and physical degradation. Guar is a legume grown in the United States and elsewhere for a wide variety of food and non-food uses.

We believe the mechanism of action for DAVANAT^® is based upon interaction with lectins, which are cell surface proteins that bind only to a particular kind of carbohydrate. DAVANAT^® is formulated to attach to specific lectins, called Galectins, which are expressed in high levels in the vast majority of tumor cells. We believe the structure of DAVANAT^® is such that it is attracted to Galectin receptors that are specific and over-expressed by cancer cells. In cancer, the mechanism of action of Davanat^® is the binding of galectins which disrupts their function in the extracellular space, on the surface of the cancer cell, or in its environment which

would include extracellular matrix and other cells such as lymphocytes and endothelium. The downstream effects of Davanat^® blocking galectin function include the alteration of tumor invasiveness and metastasis, reduction in tumor angiogenesis, enhancement of cellular immunity to tumor cells, and potentially enhancing the sensitivity of cancer cells to chemotherapy. Galectins, therefore, offer a robust target for cancer because of the potential to act in multiple ways to affect cancer cells and Davanat^® is a potent Galectin blocking agent.

Pre-clinical Studies of DAVANAT^®

Our pre-clinical studies demonstrate that DAVANAT^® when used in combination with chemotherapies, such as 5-FU and irinotecan, and biologics, such as Avastin^®, may improve the clinical benefit of anti-cancer treatments. Pre-clinical studies also demonstrated delayed tumor growth and tumor shrinkage against a control group of animals when DAVANAT^® was used in combination with standard therapies. These studies demonstrated that DAVANAT^® could be used effectively with different chemotherapies and biologics.

Clinical Trial Development of DAVANAT^®

Results from our Phase II clinical trial data in late-stage cancer patients shows that DAVANAT^® extends median survival to 6.7 months from 4.6 months (or a 46% increase) after other treatments were exhausted. The results of this trial also demonstrated reduction of adverse gastrointestinal, hematological and other side effects of chemotherapy treatment.

•

Phase I Trial for Late-Stage Patients with Solid Tumors. In 2005, we completed a Phase I study to evaluate DAVANAT^®, alone and in combination with 5-FU, to treat solid tumors in a trial of 40 end-stage patients with advanced solid tumors who failed chemotherapy, radiation therapy, and/or surgical treatments. The objective of the open label study was to evaluate the safety and tolerability of escalating doses of DAVANAT^® (30-280mg/m 2) when administered alone and in combination.

Based on objective tumor assessment using Response Evaluation Criteria in Solid Tumors, or RECIST, the disease was stabilized in 14 of 26 of the evaluable patients with measurable disease. Furthermore, 7 of 10 patients were stabilized at the highest dose level of DAVANAT^® administered in the study. Efficacy results are analyzed based on RECIST following completion of the second cycle of treatment. According to RECIST, a stable disease is a disease with neither sufficient shrinkage to qualify for Partial Response (more than 30% shrinkage) nor sufficient increase to qualify for Progressive Disease (greater than 20% increase) taking as reference the smallest sum longest diameter since the treatment started.

The Phase I data also indicate that DAVANAT^® was well tolerated by patients. The maximum tolerated dose was not reached indicating DAVANAT^® is safe and has the potential for further dose escalation. Adverse side effects were primarily disease related. Additionally, the results showed that the DAVANAT^®/5-FU combination remained in the bloodstream up to eight times longer, which we believe increases the efficacy of the treatment.

•

Phase II Trial for Late Stage Patients with Metastatic Colorectal Cancer. In 2004, we initiated a Phase II clinical trial to further evaluate DAVANAT^® for late-stage patients with metastatic colorectal cancer. The multi-center, open label, single-dose level study was designed to evaluate up to 15 patients in stage one, and up to 18 patients in stage two. The study, which was designed to evaluate the efficacy and safety of DAVANAT^® in combination with chemotherapy when administered in monthly cycles, had two objectives: (1) to document the rate of response and stabilization of patients with advanced colorectal cancer; and (2) to continue evaluating the safety of the DAVANAT^® in combination 5-FU. Dosing of patients began in May 2005. We stopped recruiting for the study in May 2006 because we achieved our objective. The data for the study indicates that based on objective tumor assessment one patient experienced a partial tumor response and the disease was stabilized in 6 of 20 patients. Data on 20 patients from this trial showed that DAVANAT^® extended median survival. We tracked these patients and gathered data after they left the trial. The patients entered the trial with disease that progressed despite previously being treated with standard chemotherapies and biologics.

•

Phase II Trial for First-line Treatment of Patients with Biliary Cancer. In 2007, we initiated a Phase II trial for the first-line treatment of patients with biliary (gall bladder) cancer. Biliary cancer may represent an opportunity for orphan drug status approval. See “FDA “Orphan Drug” Designation” below under “Government Regulation.” The multi-center, open label, single-dose level study is designed to evaluate up to 42 patients. The study was designed to evaluate the efficacy and safety of DAVANAT^® when administered for at least two monthly cycles or until disease progression. The trial had two objectives: (1) complete/partial tumor response in 20% of patients (17% in the first stage); and (2) the safety of DAVANAT^® regimen in this patient population. We stopped the trial due to financial constraints in the second quarter of 2008 and do not expect to resume it.

•

Phase II Trial for First-line Treatment of Patients with Colorectal Cancer. In 2006, we initiated a Phase II trial for initial treatment of colorectal cancer patients. The multi-center, open label, single-dose level study was designed to evaluate up to 50 patients who are unable to sustain the high toxicity of current intensive combination chemotherapy. The study was expected to evaluate the efficacy and safety of DAVANAT^® when administered in combination with the current standard of care in two monthly cycles or until disease progression or toxicity. The primary objectives of the study were a complete or partial response in 33% of the patients and a secondary measurement of progression free survival at 6 and 12 months. We stopped the trial due to financial constraints in the second quarter of 2008 and do not expect to resume it.

See “Risk Factors — Risks Related to our Company — We have one drug candidate in clinical trials and results are uncertain” for additional discussion of risks related to clinical trials.

GM and GR Series of Anti-Fibrosis Compounds

We are also developing therapeutic compounds for treatment of other serious disease, such as liver fibrosis. The GM and GR series of compounds are first-in-class, novel carbohydrate compounds that significantly reduced collagen expression and reversed fibrosis in animal models.

Uncontrolled collagen expression is a pathological process that occurs during the fibrotic process, affecting various organs leading to scar tissue. Chemical toxicity, viral infection or physical injury cause liver, renal and other types of fibrosis. According to the American Liver Foundation, more than 25 million Americans are or have been afflicted with liver and biliary diseases. The disease is even more of a problem outside the U.S. because of the prevalence of chronic hepatitis B and C that often results in fibrosis, and ultimately cirrhosis, of the liver. The area of anti-fibrotics is generating great interest based on their potential to impact chronic liver disease. The need for an effective therapeutic solution for liver fibrosis is acute, and this innovative project would significantly advance treatment in this critical area. The only current treatment for late stage fibrosis or cirrhosis is a liver transplant. Therefore, carbohydrate polymers were created and screened to inhibit collagen production in in-vivo and in-vitro fibrosis models.

In December 2010, we announced that we had entered into an extension of our research collaboration with Mount Sinai School of Medicine which began in 2006 to evaluate, in pre-clinical models, the anti-fibrotic effects of several of the Company’s novel, Galectin-targeting compounds. Mount Sinai has one of the world’s largest, most productive and well-respected liver disease investigation programs.

Dr. Scott Friedman, Chief of Liver Diseases, Division of Medicine at Mount Sinai, has performed pioneering research into the underlying causes of scarring, or fibrosis associated with chronic liver disease, which affects millions worldwide. Dr. Friedman was among the first to isolate and characterize the hepatic stellate cell, which is the key cell type responsible for scar production in liver.

In initial experiments in Dr. Friedman’s laboratory, our polysaccharide compounds that target Galectin receptors markedly reduced the markers of fibrosis in cultured stellate cells and reversed the formation of fibrotic tissue in diseased rat livers. In the extension of our research collaboration, he and his team will be testing several

of our galactomannans and rhamnogalacturonans as Galectin blockers in liver anti-fibrotic therapies. Specifically Dr. Friedman will complete the in vitro and in vivo analysis of several of our compounds for anti-fibrotic efficacy and mechanism of action using state of-the-art molecular methods to assess fibrosis, fibrogenic gene expression and liver function. This work will lead to an IND to begin clinical investigations.

Patents and Proprietary Rights

Our development and commercial viability, and ultimately our competitiveness, depend on our ability to develop and maintain the proprietary aspects of our technology and operate without infringing on the proprietary rights of others. We rely on a combination of patent, trademark, trade secret and copyright law and contract restrictions to protect the proprietary aspects of our technologies. We seek to limit disclosure of our intellectual property by requiring employees, consultants, and any third parties with access to our proprietary information to execute confidentiality agreements and by restricting access to that information.

As of December 31, 2010, we held five U.S. patents and have patent applications pending from the U.S. Patent and Trademark Office. Many of our patents and patent applications cover composition of matter for complex carbohydrate drugs and methods of use for reducing toxicity and enhancing chemotherapeutic drugs by co-administering a polysaccharide with a chemotherapeutic agent. We have corresponding patent applications pending in Europe, Canada, Israel, Brazil, Japan, China and Australia. Additionally, we have patent applications in other areas to utilize our carbohydrate-based compounds to treat disease other than cancer. See “Risk Factors — Risks Related to the Drug Development Industry — Our competitive position depends on protection of our intellectual property.

Research

Our initial focus is on the design and analysis of Galectin targeting therapeutics to improve the clinical benefit of chemotherapeutic agents and biologics. We contract with independent laboratories and other facilities to conduct our research, which is designed, evaluated and managed by our scientists. We do not anticipate building in-house research or development facilities or hiring staff other than for purposes of designing and managing our out-sourced research.

As we develop products eligible for clinical trials, we contract with independent parties to design the trial protocols, arrange for and monitor the clinical trials, collect data and analyze data. In addition, certain clinical trials for our products may be conducted by government-sponsored agencies and will be dependent on governmental participation and funding. Our dependence on independent parties and clinical sites involves risks including reduced control over the timing and other aspects of our clinical trials.

Our research and development expenditures totaled $19.5 million for the cumulative period from inception (July 10, 2000) through December 31, 2010. During the years ended December 31, 2010 and 2009, our expenditures for research and development were $1.1 million for each year.

Manufacturing and Marketing

We are a development stage company at this time and do not intend to establish internal facilities for the manufacture of our products for clinical or commercial production. To have our products manufactured, we have developed and will continue to develop relationships with third-parties that have established manufacturing capabilities. We are not a party to any long-term agreement with any of our suppliers and, accordingly, we have our products manufactured on a purchase-order basis from one of two primary suppliers.

Because our products are in the development stage, we have not created a sales and marketing staff to commercialize pharmaceutical products. If we develop products eligible for commercial sale, we will need to develop a sales and marketing capability or rely on third parties such as licensees, collaborators, joint venture

partners or independent distributors to market and sell those products. Our dependence on third-party manufacturers and marketers will involve risks relating to our reduced control, and other risks including those discussed in “Risk Factors — Risks Related to our Company — We will depend on third parties to manufacture and market our products and to design trial protocols, arrange for and monitor the clinical trials, and collect and analyze data.”

Competition

Many biotechnology and pharmaceutical companies are developing new technologies for the treatment of cancer and other diseases. While companies may broaden the market for our products they may also provide competitive alternatives to our products.

See “Risk Factors — Risks Related to the Drug Development Industry — We face intense competition in the biotechnology and pharmaceutical industries” for additional discussion related to our current and potential competition.

Government Regulation

The research, development, testing, manufacture, labeling, promotion, advertising, distribution, and marketing, among other things, of our products are extensively regulated by governmental authorities in the United States and other countries. The FDA regulates drugs under the federal Food, Drug, and Cosmetic Act and its implementing regulations. Failure to comply with the applicable U.S. requirements may subject us to administrative or judicial sanctions, such as FDA refusal to approve pending NDAs, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, and/or criminal prosecution.

Drug Approval Process

Drugs may not be marketed in the U.S. until the FDA has approved them. The steps required before a drug may be marketed in the U.S. include (similar rules may apply in other countries):

Pre-clinical laboratory tests, animal studies, and formulation studies,

Submission to the FDA of an IND for human clinical testing, which must become effective before human clinical trials may begin,

Adequate and well-controlled human clinical trials to establish the safety and efficacy of the drug for each indication,

Submission to the FDA of an NDA,

Satisfactory completion of an FDA inspection of the manufacturing facility or facilities, at which the drug is produced to assess compliance with cGMP established by the FDA,

FDA review and approval of the NDA, and

FDA review and approval of a trademark used in connection with a pharmaceutical.

Pre-clinical tests include laboratory evaluation of product chemistry, toxicity, and formulation, as well as animal studies. The results of the pre-clinical tests, together with manufacturing information and analytical data, are submitted to the FDA as part of an IND, which must become effective before human clinical trials may begin and the FDA must resolve any outstanding FDA concerns or questions before clinical trials can proceed. There is no certainty that submission of an IND will result in the FDA allowing clinical trials to begin.

Clinical trials involve the administration of the investigational drug to human subjects under the supervision of qualified investigators. Clinical trials are conducted under protocols detailing the objectives of the study, the parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated. Each protocol must be submitted to the FDA as part of the IND.

Clinical trials typically are conducted in three sequential phases, but the phases may overlap or be combined. Each trial must be reviewed and approved by an independent Institutional Review Board, IRB, before it can begin. Study subjects must sign an informed consent form before participating in a clinical trial. Phase I usually involves the initial introduction of the investigational drug into patients to evaluate its safety, dosage tolerance, pharmacodynamics, and, if possible, to gain an early indication of its effectiveness. Phase II usually involves trials in a limited patient population to (i) evaluate dosage tolerance and appropriate dosage; (ii) identify possible adverse effects and safety risks; and (iii) evaluate preliminarily the efficacy of the drug for specific indications. Phase III trials usually further evaluate clinical efficacy and test further for safety by using the drug in its final form in an expanded patient population. There is no assurance that these trials will be completed within a specified period of time, if at all.

Assuming successful completion of the required clinical testing, the results of the pre-clinical studies and of the clinical studies, together with other detailed information, including information on the manufacture and composition of the drug, are submitted to the FDA in an NDA requesting approval to market the product for one or more indications. Before approving an NDA, the FDA usually will inspect the facilities at which the drug is manufactured, and will not approve the product unless compliance with cGMP is satisfactory. If the FDA evaluates the NDA and the manufacturing facilities as acceptable, the FDA will issue an approval letter. If the FDA evaluates the NDA submission or the manufacturing facilities as not acceptable, the FDA will outline the deficiencies in the submission and often will request additional testing or information. Even if an applicant submits the requested additional information, the FDA ultimately may decide that the NDA does not satisfy the regulatory criteria for approval. The testing and approval process requires substantial time, effort, and financial resources, and there is no assurance that any approval will be granted on a timely basis, if at all. After approval, certain changes to the approved product, such as adding new indications, manufacturing changes, or additional labeling claims are subject to further FDA review and approval.

See “Risk Factors — Risks Related to the Drug Development Industry — We will need regulatory approvals to commercialize our products” for additional discussion of regulatory risks related to our drug development program.

FDA Priority Review

FDA procedures provide for priority review of an NDA submitted for drugs that, compared to currently marketed products, offer a significant improvement in the treatment, diagnosis, or prevention of a disease. NDAs that are granted priority review are acted upon more quickly than NDAs given standard review. If we were to seek priority review, there can be no guarantee that the FDA will grant priority review status, that priority review status will affect the time of review, or that the FDA will approve the NDA submitted for any of our product candidates, whether or not priority review status is granted.

Post-Approval Requirements

If FDA approval of one or more of our products is obtained, we will be required to comply with a number of post-approval requirements. For example, holders of an approved NDA are required to report certain adverse reactions to the FDA and to comply with certain requirements concerning advertising and promotional labeling for their products. Also, quality control and manufacturing procedures must continue to conform to cGMP after approval, and the FDA periodically inspects manufacturing facilities to assess compliance with cGMP. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance. In addition, discovery of problems with a product after approval may result in restrictions on a product, manufacturer, or holder of an approved NDA, including withdrawal of the product from the market. Also, new government requirements may be established that could delay or prevent regulatory approval of our products under development.

Regulation Outside the United States

Before our products can be marketed outside of the United States, they are subject to regulatory approval similar to that required in the United States, although the requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary widely from country to country. No action can be taken to market any product in a country until an appropriate application has been approved by the regulatory authorities in that country. The current approval process varies from country to country, and the time spent in gaining approval varies from that required for FDA approval. In certain countries, the sales price of a product must also be approved. The pricing review period often begins after market approval is granted. No assurance can be given that even if a product is approved by a regulatory authority, satisfactory prices will be approved for such product.

Environmental Regulation

Pharmaceutical research and development involves the controlled use of hazardous materials. Biotechnology and pharmaceutical companies must comply with laws and regulations governing the use, generation, manufacture, storage, air emission, effluent discharge, handling and disposal of certain materials, biological specimens and wastes. We do not anticipate building in-house research, development or manufacturing facilities, and, accordingly, do not expect to have to comply directly with environmental regulation. However, our contractors and others conducting research, development or manufacturing activities for us may be required to incur significant compliance cost, and this could in turn could increase our expense or delay our completion of research or manufacturing programs.

Employees

As of December 31, 2010, we had six full-time employees, two of whom were involved primarily in management of our pre-clinical research and development and clinical trials and four who were involved primarily in financial management and administration of our company. We also had four part-time contractors, one of whom serves as our medical director, one of whom provides manufacture and clinical trial support and two of whom provide financial management services.

Properties

We lease 9,400 square feet for our executive offices located at 7 Wells Avenue, Newton, Massachusetts. We have a five year lease that commenced in August 2006 with an option to extend for an additional five years. We believe this space is suitable for our present operations and adequate for foreseeable expansion of our business.

Legal Proceedings

Other than claims and legal proceedings that arise from time to time in the ordinary course of business which are not material, we have no pending legal proceedings except as follows:

On January 30, 2008, Custom Equity Research, Incorporated (d/b/a Summer Street Research Partners) (“Summer Street”) filed a lawsuit against us in the Superior Court of the Commonwealth of Massachusetts, alleging claims for breach of contract, declaratory judgment and unjust enrichment arising out of an engagement letter under which Summer Street agreed to provide institutional investment placement services to us. Summer Street claims it is entitled to a placement fee for each placement made during the term of the agreement and for each issuance of securities made or agreed to be made by us from October 17, 2007 through November 16, 2008. We initially responded to the lawsuit with a motion to dismiss, which the Court denied on June 23, 2008, finding that the letter agreement was ambiguous with respect to Summer Street’s entitlement to compensation. The Court also denied Summer Street’s motion for a prejudgment attachment and trustee process, preliminarily finding that Summer Street was not likely to prevail on any of its claims. We filed an answer denying Summer Street’s material allegations. Discovery is currently under way. A trial date has been set for November 8, 2011. We believe the lawsuit is without merit and intends to contest it vigorously.

We are in receipt of a letter dated January 12, 2011 from Maxim Group (“Maxim”), which has acted as a Placement Agent for us. The letter advises that Maxim has been named as a respondent in a FINRA arbitration matter commenced by Summer Street, alleging claims for tortious interference with advantageous business and contractual relations, fraud and deceit, negligent misrepresentation, unjust enrichment, violation of Massachusetts Consumer Protection Act, Mass. Gen. Laws ch. 93A, and civil conspiracy, arising out of our termination of our relationship with Summer Street and its engagement of Maxim as its placement agent. We have agreed to indemnify and provide a defense to Maxim in accordance with the Placement Agreements between Maxim and us. We believe that the arbitration is without merit and intend to assist Maxim in its vigorous defense.

Because shares of our common stock are held by depositaries, brokers and other nominees, the number of beneficial holders of our shares is substantially larger than the number of record holders. Based on information available to us, we believe there are 6,652 non-objecting beneficial owners of our shares of our common stock in addition to the record holders.

Dividends

There have been no cash dividends declared on our common stock since our company was formed. Dividends are declared at the sole discretion of our Board of Directors. Our intention is not to declare cash dividends and retain all cash for our operations.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

In addition to historical information, the following Management’s Discussion and Analysis of Financial Condition and Results of Operations contains forward-looking statements as defined under federal securities laws and is subject to the safe harbor created therein for forward-looking statements. Such statements include, but are not limited to, statements concerning our anticipated operating results, research and development, clinical trials, regulatory proceedings, and financial resources, and can be identified by use of words such as, for example, “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe” and “would,” “should,” “could” or “may.” Forward-looking statements are based on current expectations, estimates and projections about the industry and markets in which Pro-Pharmaceuticals operates, and management’s beliefs and assumptions. These statements are not guarantees of future performance and involve certain known and unknown risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such statements. Such risks and uncertainties are related to, without limitation, our early stage of development, our dependence on outside capital, uncertainties of our technology and clinical trials, intellectual property litigation, uncertainties of regulatory approval requirements for our products, competition and stock price volatility in the biotechnology industry, limited trading volume for our stock, concentration of ownership of our stock, and other risks detailed herein and from time to time in our SEC reports. The following discussion should be read in conjunction with the accompanying consolidated financial statements and notes thereto of Pro-Pharmaceuticals appearing elsewhere herein.

Overview

We are a development-stage company engaged in the discovery and development of therapeutic compounds that target Galectin receptors that we believe enhance existing cancer treatments. We believe our therapeutics could also be used in the treatment of liver, microbial and inflammatory diseases. All of our products are presently in development, including pre-clinical and clinical trials.

Since our inception on July 10, 2000, our primary focus has been the development of a new generation of anti-cancer treatments using polysaccharide polymers which are designed to increase survival and improve the quality of life for cancer patients. Our lead product candidate, DAVANAT^®, is a patented, new chemical entity that we believe, when administered in combination with chemotherapies or biologics, or vaccines increases efficacy while reducing serious adverse effects. We hold the patent on DAVANAT^®, without any licensing or royalty obligations.

At December 31, 2010, we had $5,891,000 of unrestricted cash to fund our operations. Subsequent to year end through March 15, 2011, we received $2,209,000 from the exercise of warrants and options for 3,757,472 shares of our common stock. Also, we issued an additional 13 shares of Series C for $130,000 and received a grant payment of $234,000. We believe that with the cash received subsequent to year end and the cash on hand at December 31, 2010, there is sufficient cash to fund operations through 2012. We will require more cash to fund our operations and believe we will be able to obtain additional financing. However, there can be no assurance that we will be successful in obtaining such new financing or, if available, that such financing will be on terms favorable to us.

Development of DAVANAT^® Technology

In 2002, the FDA granted an Investigational New Drug (“IND”) application for us to administer DAVANAT^® in combination with 5-FU to treat late-stage cancer patients with solid tumors. 5-FU is FDA-approved, and one of the most widely used chemotherapies for treatment of various types of cancer, including colorectal, breast and gastrointestinal. We believe that using DAVANAT^® in combination with 5-FU enables greater absorption of the chemotherapy in cancer cells while reducing its toxic side effects.

The FDA also has granted us an IND for DAVANAT^® to be administered with Avastin^®, 5-FU and leucovorin in a combination therapy to treat early-stage colorectal cancer patients and an IND for DAVANAT^®

to be administered with 5-FU to treat early stage bile duct cancer patients. In addition, the FDA also has granted us, on a case-by-case basis, the ability to treat patients with breast cancer in response to physicians’ requests for so-called “compassionate use”.

To date, DAVANAT^® has been administered to approximately 100 cancer patients. Data from a Phase II trial for end-stage colorectal cancer patients showed that DAVANAT^® in combination with 5-FU extended median survival to 6.7 months with significantly reduced side effects, as compared to 4.6 months for best standard of care as determined by the patients’ physicians. These clinical trials also showed that patients experienced fewer adverse side effects of the chemotherapy and required less hospitalization.

Our pre-clinical and clinical trial data also show that DAVANAT^® is well tolerated, safe and non-toxic.

We believe, based on the outcome of our clinical trials to date, that DAVANAT^®, when co-administered with 5-FU or other chemotherapies or biologics is superior to the current standard of care. We plan to file NDAs for DAVANAT^® in combination with other chemotherapies, biologics and vaccines.

According to its published guidance, the FDA initially determines whether a New Drug Application (“NDA”) filing is complete for purposes of allowing a review, and, if allowed, then determines whether to approve the NDA, a process that takes six or ten months. Upon approval, an applicant may commence commercial marketing and distribution of the approved products.

In May 2008, we submitted a Drug Master File (“DMF”) for DAVANAT^® to the FDA. This is an important step toward the filing of our DAVANAT^® NDA because a DMF contains confidential detailed information in support of the NDA about facilities, processes or articles used in the chemistry, manufacturing, controls, processing, packaging, and storing or stability of drugs. We believe the DMF represents a significant milestone in our eventual commercialization of DAVANAT^® because it demonstrates our ability to produce commercial quantities of pharmaceutical-grade DAVANAT^® under current Good Manufacturing Process (“cGMP”) standards. A DMF can be cross-referenced by potential partners to use in combination with other therapies to expedite clinical studies and submission of NDAs.

In September 2008, we submitted a clinical and pre-clinical package to the FDA in support of our DAVANAT^® NDA. The FDA reported to us in its minutes for the December 2008 meeting that we will be required to conduct a Phase III trial to demonstrate superiority to the best standard of care for late stage colorectal cancer patients. We expect to meet with the FDA to finalize our plans for the Phase III trial.

On December 17, 2010, we met with officials from the FDA to present our Phase III clinical development program for DAVANAT^®. Agreement was reached on the design of pivotal, randomized, controlled, and blinded Phase III clinical trials of DAVANAT^® co-administered with standard chemotherapy for second line treatment of patients with metastatic colorectal cancer.

On March 9th, 2011 we announced that our Board of Directors named Peter G. Traber, M.D., President and Chief Executive Officer, effective March 17, 2011. Prior to being named President and Chief Executive Officer, Dr. Traber had been our interim Chief Medical Officer and has been a member of our Board of Directors since February 2009. Dr. Traber was President Emeritus and former Chief Executive Officer of Baylor School of Medicine. His previous positions include Senior Vice President of Clinical Development and Medical Affairs and Chief Medical Officer of GlaxoSmithKline, and Chief Executive Officer of the University of Pennsylvania Health System. Dr. Traber succeeds Theodore D. Zucconi, Ph.D., who will continue as a member of the Board of Directors. Dr. Zucconi also will direct Company operations with a focus on approvals and expansion of the Latin American business and manufacturing.

Agreement with PROCAPS S.A.

On March 25, 2010, we granted PROCAPS S.A. (“PROCAPS”) exclusive rights to market and sell DAVANAT^® to treat cancer in Colombia, South America. PROCAPS is a large, international, privately held pharmaceutical company based in Barranquilla, Colombia. Under terms of the agreement, PROCAPS is responsible for obtaining regulatory and pricing approval in Colombia, South America. PROCAPS also will be responsible for the vial filling, packaging, marketing and distribution of DAVANAT^® in the region.

Once approved for sale by regulators, we will receive a transfer payment for each dose of DAVANAT^® shipped to PROCAPS, in addition to a royalty above a minimum annual sales threshold. In October 2010, we received payment of $200,000 and shipped DAVANAT^® to PROCAPS for testing purposes. We retain all intellectual property rights and we are the owner of the regulatory approval of DAVANAT^® in the region. PROCAPS has first negotiation rights to other countries in South and Central America and the Caribbean. Should we gain approval in Colombia, PROCAPS may then obtain the marketing authorization in 10 countries in Latin America.

The Company recorded the $200,000 payment as deferred revenue on the consolidated balance sheet as of December 31, 2010 and will recognize the revenue when the remaining deliverables of the collaboration agreement have been completed.

Results of Operations from the Years Ended December 31, 2010 and 2009

Research and Development Expense


	Year ended December 31,				2010 as Compared to 2009
	2010		2009		$ Change			% Change
	(in thousands, except %)
Research and development	$	1,066	$	1,110	$	(44	)		(4	)%

We generally categorize research and development expenses as either direct external expenses, comprised of amounts paid to third party vendors for services, or all other research and development expenses, comprised of employee payroll and general overhead allocable to research and development. We subdivide external expenses between clinical programs and pre-clinical activities. We consider a clinical program to have begun upon acceptance by the FDA, or similar agency outside of the United States, to commence a clinical trial in humans, at which time we begin tracking expenditures by the product candidate. We have one product candidate – DAVANAT^® – in clinical trials at this time. Clinical program expenses comprise payments to vendors related to preparation for, and conduct of, all phases of the clinical trial, including costs for drug manufacture, patient dosing and monitoring, data collection and management, oversight of the trials and reports of results. Pre-clinical expenses comprise all research and development amounts incurred before human trials begin, including payments to vendors for services related to product experiments and discovery, toxicology, pharmacology, metabolism and efficacy studies, as well as manufacturing process development for a drug candidate.

Our research and development expenses for the years ended December 31, 2010 and 2009 were as follows:


	Year Ended December 31,
	2010		2009
	(in thousands)
Direct external expenses:
Clinical programs	$	608	$	114
Pre-clinical activities		38		380
All other research and development expenses		420		616

	$	1,066	$	1,110

The decrease in our research and development expense for the year ended December 31, 2010 versus the same period in 2009 is due primarily to decreased pre-clinical activities and other research and development expenses offset by increased clinical programs related to a planned Phase III trial. Included in clinical programs are warrant expenses related to consultants ($222,000) during year ended December 31, 2010. The decrease in other research and development expenses is primarily due to decreased salary expenses ($54,000) and decreased stock-based compensation ($139,000). We plan to initiate a Phase III trial as soon as we raise sufficient additional funds which will serve to increase our research and development expense.

Both the time required and costs we may incur in order to commercialize a drug candidate that would result in material net cash inflow are subject to numerous variables, and therefore we are unable at this stage of our development to forecast useful estimates. Variables that make estimates difficult include the number of clinical trials we may undertake, the number of patients needed to participate in the clinical trial, patient recruitment uncertainties, trial results as to the safety and efficacy of our product, and uncertainties as to the regulatory agency response to our trial data prior to receipt of marketing approval. Moreover, the FDA or other regulatory agencies may suspend clinical trials if we or an agency believes patients in the trial are subject to unacceptable risks, or find deficiencies in the conduct of the clinical trial. Delays or rejections may also occur if governmental regulation or policy changes during our clinical trials or in the course of review of our clinical data. Due to these uncertainties, accurate and meaningful estimates of the ultimate cost to bring a product to market, the timing of costs and completion of our program and the period during which material net cash inflows will commence are unavailable at this time.

General and Administrative Expense


	Year ended December 31,				2010 as Compared to 2009
	2010		2009		$ Change			% Change
	(in thousands, except %)
General and administrative	$	3,817	$	4,983	$	(1,166	)		(23	)%

General and administrative expenses consist primarily of salaries, including stock based compensation, legal and accounting fees, insurance, investor relations, business development and other office related expenses. The primary reason for the decrease for the year ended December 31, 2010 as compared to the same period in 2009 is due to decreased payroll ($710,000) primarily as the result of the recognition of severance obligations in 2009 related to the departure of our former chief executive officer, decreased stock-based compensation expense ($291,000) and decreased legal and accounting costs ($557,000) primarily due to trade secrets litigation in 2009, offset by increased business development expenses ($471,000) as we increased our efforts to gain regulatory approval to commercialize DAVANAT^® in South America.

Other Income and Expense

Other income and expense for the years ended December 31, 2010 and 2009 was a loss of $746,000 and $1,369,000, respectively. The loss for the year ended December 31, 2010 was due primarily to the change in fair value of warrant liabilities ($1,241,000) offset by other income ($489,000) related to a research grant. The loss for the year ended December 31, 2009 was due primarily to the change in fair value of warrant liabilities.

We were notified in November 2010 by the Internal Revenue Service that we have been awarded a total grant of $489,000 under the Qualifying Therapeutic Discovery Project Program (Section 48D of the Internal Revenue Code) for DAVANAT^® and our GR/GM-Series of anti-fibrotic, cirrhosis compounds. Of this amount, $255,000 was received in 2010 with the remaining $234,000 received in February 2011 and included in grant receivable on the consolidated balance sheet at December 31, 2010.

Liquidity and Capital Resources

As described above in the Overview and elsewhere in this Annual Report on Form 10-K, we are in the development stage and have not generated any revenues to date. Since our inception on July 10, 2000, we have financed our operations from proceeds of public and private offerings of debt and equity. As of December 31, 2010, we raised a net total of $52.2 million from these offerings. At December 31, 2010, we had $5,891,000 of unrestricted cash and cash equivalents available to fund future operations. Subsequent to year end through March 15, 2011, we received $2,209,000 from the exercise of warrants and options for 3,757,472 shares of our common stock. Also, we issued an additional 13 shares of Series C for $130,000 and received a grant payment of $234,000. We believe that with the funds received subsequent to year end and the cash on hand at December 31, 2010, there is sufficient cash to fund operations through 2012.

We will require more cash to fund our operations and believe we will be able to obtain additional financing. However, there can be no assurance that we will be successful in obtaining such new financing or, if available, that such financing will be on terms favorable to us. We are actively seeking to raise additional capital and have significantly reduced our administrative and clinical spending. If we are unsuccessful in raising additional capital by December 2012, we may be required to cease operations or seek bankruptcy protection. Net cash used in operations decreased by $785,000 to $3,102,000 for 2010, as compared to $3,887,000 for 2009. Cash operating expenses decreased principally due to decreased general and administrative costs as a result of cost containment measures during the period which required overall lower cash expenditures.

No cash was provided by or used in investing activities during 2010, essentially unchanged from the same period in 2009.

Net cash provided by financing activities was $8,742,000 during 2010 as compared to $3,820,000 during 2009, due primarily to the transactions described below.

Payments Due Under Contractual Obligations

The following table summarizes the payments due under our contractual obligations at December 31, 2010, and the effect such obligations are expected to have on liquidity and cash flow in future periods:


	Payments due by period (in thousands)

Operating leases	$	167	$	167	$	—	$	—	$	—
Separation agreement		293		293		—		—		—

Total payments due under contractual obligations	$	460	$	460	$	—	$	—	$	—

Operating leases. On May 1, 2006, we entered into an operating lease for office space. The lease commenced on August 11, 2006, and extends for five years and terminates on September 30, 2011. The lease provides for annual base rental payments of $235,000 in the first year, increasing in each subsequent lease year to $244,000, $253,000, $263,000 and $273,000, respectively. In addition to base rental payments included in the

contractual obligations table above, we are responsible for our pro-rata share of increases in the operating expenses for the building after calendar year 2006 and taxes for the building after fiscal year 2007. We have the option to extend the term of the lease for an additional five year period at the prevailing market rate at the time of exercise. In connection with this lease, a commercial bank has issued a letter of credit collateralized by cash we have on deposit with the bank of $59,000. Additionally, we have a non-cancellable lease for a car, for our former chief executive officer, which expired in January 2011 and which is included in the severance agreement line of the contractual obligations table.

Separation agreement. In February 2009, we entered into a Separation Agreement in connection with the resignation of David Platt, Ph.D., our former Chief Executive Officer and Chairman of the Board of Directors. The Separation Agreement provides that we shall continue to pay Dr. Platt his current salary at a monthly rate of $21,667 for 24 months and that we may defer payment of a portion of such salary amounts greater than $10,000 per month (so long as Dr. Platt does not receive payments of less than the salary payments being made to the Company’s Chief Executive Officer). However, all deferred amounts will continue to accrue and will be payable on the earlier of (i) the Company receiving a minimum of $4.0 million of funding after February 12, 2009, or (ii) February 12, 2011. We also agreed to continue to (i) provide health and dental insurance benefits to Dr. Platt, until the first to occur of February 12, 2011 or the date Dr. Platt and his family become eligible to receive health and dental insurance benefits under the plans of a subsequent employer and (ii) make the current monthly lease payments on his automobile until February 12, 2011. We recognized the full amount of the salary, health insurance and automobile during the first quarter of 2009. The remaining liability related to this severance is reflected in accrued expenses ($293,000) on the consolidated balance sheet at December 31, 2010 and in accrued expenses ($154,000) and other long-term liabilities ($280,000) on the consolidated balance sheet at December 31, 2009. The final payment was paid to Dr. Platt on February 12, 2011.

The Separation Agreement also provides for the deferral of a $1.0 million severance payment due to Dr. Platt under his employment agreement until the occurrence of any of the following milestone events: (i) the approval by the Food and Drug Administration for a new drug application (“NDA”) for any drug candidate or drug delivery candidate based on the DAVANAT^® technology (whether or not such technology is patented). We also will grant Dr. Platt fully vested cashless stock option with identical terms to purchase at least 500,000 shares of common stock; (ii) consummation of a transaction with a pharmaceutical company expected to result in at least $10.0 million of equity investment or $50 million of royalty revenue to the Company. We also will grant Dr. Platt fully vested cashless-exercise stock options exercisable to purchase at least 300,000 shares of our common stock for ten (10) years at an exercise price not less than the fair market value of the Common Stock determined as of the date of the grant; or (iii) the renewed listing of our securities on a national securities exchange. Payment upon the events (i) and (iii) may be deferred up to nine months, and if we have insufficient cash at the time of any of such events, we may issue Dr. Platt a secured promissory note for such amount. If we file a voluntary or involuntary petition for bankruptcy, whether or not a milestone event has occurred, such event shall trigger our obligation to pay the $1.0 million with the result that Dr. Platt may assert a claim for such obligation against the bankruptcy estate. Due to the uncertainties regarding the achievement of any of the milestones as described, we have not accrued for the $1.0 million severance nor have we recognized the value of the unissued stock options as of December 31, 2010. When it is deemed probable that one or more of the milestone events will be achieved, we will then recognize the $1.0 million severance and the expense related to the issuance of the stock option at that time based on the then current fair value.

Other. We have engaged outside vendors for certain services associated with our clinical trials. These services are generally available from several providers and, accordingly, our arrangements are typically cancellable on 30 days notice.

Off-Balance Sheet Arrangements

We have not created, and are not a party to, any special-purpose or off-balance sheet entities for the purpose of raising capital, incurring debt or operating parts of our business that are not consolidated into our financial statements. We do not have any arrangements or relationships with entities that are not consolidated into our financial statements that are reasonably likely to materially affect our liquidity or the availability of capital resources.

Critical Accounting Policies and Estimates

Our significant accounting policies are more fully described in Note 2 to our consolidated financial statements included elsewhere in this Registration Statement on Form S-1. Certain of our accounting policies, however, are critical to the portrayal of our financial position and results of operations and require the application of significant judgment by our management, which subjects them to an inherent degree of uncertainty. In applying our accounting policies, our management uses its best judgment to determine the appropriate assumptions to be used in the determination of certain estimates. Our more significant estimates include stock option and warrant liability valuations and performance vesting features of certain of these instruments, useful lives and potential impairment of property and equipment and intangible assets, accrued liabilities, deferred income taxes and cash flow. These estimates are based on our historical experience, terms of existing contracts, our observance of trends in the industry, information available from other outside sources, and on various other factors that we believe to be appropriate under the circumstances. We believe that the critical accounting policies discussed below involve more complex management judgment due to the sensitivity of the methods, assumptions and estimates necessary in determining the related asset, liability, revenue and expense amounts.

Intangible Assets. Intangible assets include patent costs, consisting primarily of related legal fees, which are capitalized as incurred and amortized over an estimated useful life of five years from issuance. We review the intangible assets for potential impairment on an annual basis or whenever events or changes in circumstances indicate that the asset may be impaired.

Accrued Expenses. As part of the process of preparing our consolidated financial statements, we are required to estimate accrued expenses. This process involves identifying services that third parties have performed on our behalf and estimating the level of service performed and the associated cost incurred on these services as of each balance sheet date in our consolidated financial statements. Examples of estimated accrued expenses include contract service fees in conjunction with pre-clinical and clinical trials, professional service fees, such as those arising from the services of attorneys and accountants and accrued payroll expenses. In connection with these service fees, our estimates are most affected by our understanding of the status and timing of services provided relative to the actual services incurred by the service providers. In the event that we do not identify certain costs that have been incurred or we under- or over-estimate the level of services or costs of such services, our reported expenses for a reporting period could be understated or overstated. The date on which certain services commence, the level of services performed on or before a given date, and the cost of services are often subject to our judgment. We make these judgments based upon the facts and circumstances known to us in accordance with accounting principles generally accepted in the U.S.

Warrants. We have issued common stock warrants in connection with the execution of certain equity and debt financings and consulting agreements. Certain warrants are accounted for as derivative liabilities at fair value. Such warrants do not meet the criteria that a contract should not be considered a derivative instrument if it is (1) indexed to its own stock and (2) classified in stockholders’ equity. Changes in fair value of derivative liabilities are recorded in the consolidated statement of operations under the caption “Change in fair value of warrant liabilities.” Warrants that are not considered derivative liabilities are accounted for at fair value at the date of issuance in additional paid-in capital. The fair value of warrants is determined using the Black-Scholes option-pricing model using assumptions regarding volatility of our common share price, remaining life of the warrant, and risk-free interest rates at each period end.

Stock-Based Compensation. Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the service period, which generally represents the vesting period. For awards that have performance based vesting conditions we recognize the expense over the estimated period that the awards are expected to be earned. We use the Black-Scholes option-pricing model to calculate the grant date fair value of stock options. The expense recognized over the service period is required to include an estimate of the awards that will be forfeited.

Research and Development Expenses. Costs associated with research and development are expensed as incurred. Research and development expenses include, among other costs, salaries and other personnel-related costs, and costs incurred by outside laboratories and other accredited facilities in connection with clinical trials and preclinical studies.

Recent Accounting Pronouncements

In January 2010, the Financial Accounting Standards Board issued Accounting Standards Update No. 2010-06 for Fair Value Measurements and Disclosures (Topic 820): Improving Disclosures about Fair Value Measurements. This Update requires new disclosures for transfers in and out of Level 1 and 2 and activity in Level 3. This Update also clarifies existing disclosures for level of disaggregation and about inputs and valuation techniques. The new disclosures are effective for interim and annual periods beginning after December 15, 2009, except for the Level 3 disclosures, which are effective for fiscal years beginning after December 15, 2010 and for interim periods within those years. Other than requiring additional disclosures, adoption of this new guidance did not have a material impact on the Company’s financial statements and is not expected to have a significant impact on the reporting of the Company’s financial condition or results of operations.

In April 2010, the FASB issued ASU No. 2010-17, Revenue Recognition — Milestone Method. This ASU provides guidance on the criteria that should be met for determining whether the milestone method of revenue recognition is appropriate. Under the milestone method of revenue recognition, consideration that is contingent upon achievement of a milestone in its entirety can be recognized as revenue in the period in which the milestone is achieved only if the milestone meets all criteria to be considered substantive. This standard provides the criteria to be met for a milestone to be considered substantive which includes that: a) performance consideration earned by achieving the milestone be commensurate with either performance to achieve the milestone or the enhancement of the value of the item delivered as a result of a specific outcome resulting from performance to achieve the milestone; and b) it relates to past performance and be reasonable relative to all deliverables and payment terms in the arrangement. This standard is effective on a prospective basis for milestones achieved in fiscal years beginning on or after June 15, 2010. Although the Company is still evaluating the impact of this standard, management does not expect its adoption to have a material impact on the Company’s financial condition or results of operations.

Director Independence

The Company’s Corporate Governance provides that a majority of the members of the Board, and each member of the Audit, Compensation and Nominating and Corporate Governance Committees, must meet certain criteria for independence. Based on the New York Stock Exchange independence requirements, the Company’s Corporate Governance practices assist the Board in its determination of director independence.

Based on the New York Stock Exchange rules, Messrs. Czirr, Martin, Greenberg, Neill, Prelack, Rome and Dr. Amelio were affirmatively determined by the Board to be independent. Due to Dr. Zucconi’s and Dr. Traber’s employment with the Company, they are not considered independent. Also, none of the non-employee directors has any relationship with the Company other than being a director and stockholder, or any transaction or arrangement that interferes with each director’s independence.

Policies with Respect to Transactions with Related Persons

The Nominating and Corporate Governance Committee and the Board have adopted a Code of Ethics, which is available at www.pro-pharmaceuticals.com, that sets forth various policies and procedures intended to promote the ethical behavior of the Company’s employees, officers and directors. The Code of Ethics describes the Company’s policy on conflicts of interest. The Nominating and Corporate Governance Committee monitors the ethical behavior of the Company’s employees, officers and directors.

The executive officers and the Board are also required to complete a questionnaire on an annual basis which requires them to disclose any related person transactions and potential conflicts of interest. The responses to these questionnaires are reviewed by outside corporate counsel, and, if a transaction is reported by an independent director or executive officer, the questionnaire is submitted to the Chairperson of the Audit Committee for review. If necessary, the Audit Committee will determine whether the relationship is material and will have any effect on the director’s independence. After making such determination, the Audit Committee will report its recommendation on whether the transaction should be approved or ratified by the entire Board.

Certain Relationships and Related Transactions

Since the beginning of fiscal 2009, the Company did not participate in any transactions in which any of the directors, Class B directors, executive officers, any beneficial owner of more than 5% of the Company’s common stock, nor any of their immediate family members, had a direct or indirect material interest. During 2010, we entered into an agreement with one of the members of our Board of Directors, Dr. Peter Traber, to serve as our interim Chief Medical Officer. For his services during 2010, Dr. Traber earned fees of $32,500 ($5,000 of which was paid in January 2011) and was granted warrants for 600,000 shares of our common stock.

Material Terms of Employment Contracts of Named Executive Officers

Theodore D. Zucconi, PhD., Former Chief Executive Officer and President

In connection with the sale of our Series B preferred stock to the 10X Fund, Dr. Zucconi was appointed as our Chief Executive Officer and President effective February 12, 2009, serving in that position through March 16, 2011. Peter G. Traber, M.D. became our Chief Executive Officer and President on March 17, 2011. As of the date of this prospectus we have not entered into a definitive employment agreement with him.

On March 31, 2011, we entered into a Separation Agreement with Dr. Zucconi which supersedes his prior employment agreement described below. Under the separation agreement, Dr. Zucconi shall serve as a consultant, with the title Director of Business Development, in connection with such matters as we may request, including the program for approval, marketing and sale of our DAVANAT^® product in South American or Latin American countries. The separation agreement provides for a consultancy term ending between November 30, 2011 and March 31, 2012 at a monthly rate of $13,333 and terminates all stock options that had not vested under his prior employment agreement. The separation agreement entitles Dr. Zucconi to a grant of 300,000 stock options exercisable for seven years which vest as to 100,000 shares each upon approval milestones in up to three South American countries achieved during his consultancy; a cash bonus equal to 1% of the amount received by June 30, 2012 from (i) actual receipts of gross sales of DAVANAT^® in South and Latin American countries and (ii) licensing fees paid in connection with agreements to market DAVANAT^® in such countries other than Colombia; and health and dental coverage for up to 24 months. The separation agreement also contains mutual general releases of Dr. Zucconi and Pro-Pharmaceuticals and their respective related entities and persons.

On May 21, 2009, we entered into an employment agreement with Dr Zucconi (the “Agreement”) for a term ending May 31, 2011. The Agreement provides for an annual salary of $260,000, retroactive to February 12, 2009, which may be adjusted proportionately to the adjustments for other executives, provided that any reductions of 2009 compensation shall be paid no later than the first calendar quarter of 2010. Due to cash conservation efforts, Dr. Zucconi agreed to work for a base monthly salary of $10,000 in 2009. On December 31, 2009, Dr. Zucconi and the Company agreed that we owe him no unpaid 2009 salary except for accrued vacation. As incentives, Dr. Zucconi is entitled to grants of up to 2,000,000 stock options, which at his election may be

incentive stock options or non-qualified stock options, to purchase shares of our common stock as follows: (i) 400,000 as of the effective date of the Agreement, (ii) 150,000 with a vesting date of December 31, 2009; (iii) 200,000 with a vesting date of December 31, 2010; and upon achieving the following milestones: (a) 100,000 after the effective date of an investigational new drug application by the U.S. Food and Drug Administration (“FDA”), e.g., for fibrosis or anti-hypoxia, filed by the Company, a partner, an agent or subsidiary; (b) 300,000 for any FDA approval of marketing and sales of DAVANAT^®; (c) 100,000 for each of first three agreements to sell/distribute a product; (d) 150,000 for the initiation of sales of DAVANAT^® anywhere in the world; (e) 150,000 for the initiation of sales of DAVANAT^® specifically in the United States; and (f) 250,000 following the first calendar quarter in which we achieve profitability. The stock options are exercisable for seven years whether or not Dr. Zucconi is then employed by us, are priced on the date of approval of this agreement, shall vest as indicated and contain a “cashless” exercise provision. Dr. Zucconi may elect to take stock instead of stock options.

The Agreement provides that Dr. Zucconi shall be entitled to cash bonus payments as follows: (i) $100,000 of which $20,000 is paid when an additional $1 million is raised and $40,000 when each additional $1 million is received until the total is paid; (ii) 2% of financing introduced from sources identified by Dr. Zucconi and not from sources, or their successors, previously identified by us or 10X Capital Management; and (iii) 1% of the upfront fees and milestone payments in the event a partnership or joint venture is formed to sell or distribute a Company drug or reached with another company with upfront fees and milestone payments. In 2009, Dr. Zucconi received $20,000 cash bonus.

The Agreement entitles Dr. Zucconi to: (i) an automobile allowance of $500 per month; (ii) use of an apartment within reasonable commuting distance of our principal offices, and up to $20,000 per year additional temporary living costs; (iii) fourteen round trip single passenger airline tickets (by coach) per year between Massachusetts and Phoenix, Arizona; (iv) participation in our 401(k) plan with an employer match; and (v) medical insurance through us or reimbursement for premiums paid by Dr. Zucconi.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth, as of March 15, 2011, certain information concerning the beneficial ownership of our common stock, our Series A preferred stock and our Series B preferred stock by (i) each person known by us to own beneficially five per cent (5%) or more of the outstanding shares of each class, (ii) each of our directors and named executive officers, and (iii) all of our executive officers and directors as a group. The table also sets forth, in its final column, the combined voting power of the voting securities on all matters presented to the stockholders for their approval at the Annual Meeting, except for such separate class votes as are required by law.

The number of shares beneficially owned by each 5% stockholder, director or executive officer is determined under the rules of the Securities and Exchange Commission, or SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. Under those rules, beneficial ownership includes any shares as to which the individual or entity has sole or shared voting power or investment power and also any shares that the individual or entity has the right to acquire within 60 days after March 15, 2011 through the exercise of any stock option, warrant or other right, or the conversion of any security. Unless otherwise indicated, each person or entity has sole voting and investment power (or shares such power with his or her spouse) with respect to the shares set forth in the following table. The inclusion in the table below of any shares deemed beneficially owned does not constitute an admission of beneficial ownership of those shares.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Pro-Pharmaceuticals, Inc.

Newton, Massachusetts

We have audited the accompanying consolidated balance sheet of Pro-Pharmaceuticals, Inc. and subsidiaries (a development stage company) (the “Company”) as of December 31, 2010, and the related consolidated statements of operations, changes in redeemable convertible preferred stock and stockholders’ deficit, and cash flows for the year then ended, and for the period from inception (July 10, 2000) to December 31, 2010. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audit. The financial statements for the period from inception (July 10, 2000) to December 31, 2009 were audited by other auditors and our opinion, insofar as it rates to cumulative amounts included for such prior periods, is based solely on the report of other such auditors.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, based on our audit and the report of other auditors, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2010, and the results of their operations and their cash flows for the year then ended, and for the period from inception (July 10, 2000) to December 31, 2010 in conformity with accounting principles generally accepted in the United States of America.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Pro-Pharmaceuticals, Inc.

Newton, Massachusetts

We have audited the accompanying consolidated balance sheet of Pro-Pharmaceuticals, Inc. and subsidiaries (a development stage company) (the “Company”) as of December 31, 2009, and the related consolidated statements of operations, changes in redeemable convertible preferred stock and stockholders’ deficit, and cash flows for the year then ended, and for the period from inception (July 10, 2000) to December 31, 2009 (not presented herein). These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audit.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2009, and the consolidated results of their operations and their cash flows for the year then ended, and for the period from inception (July 10, 2000) to December 31, 2009 in conformity with accounting principles generally accepted in the United States of America.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company’s recurring losses from operations and stockholders’ deficit raise substantial doubt about its ability to continue as a going concern. Management’s plans concerning these matters are also discussed in Note 1 to the consolidated financial statements. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

As discussed in Note 8 to the financial statements, the Company changed the manner in which it accounts for certain warrants effective January 1, 2009.

PRO-PHARMACEUTICALS, INC.

(A DEVELOPMENT-STAGE COMPANY)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.	Nature of Business and Basis of Presentation

Pro-Pharmaceuticals, Inc. (the “Company”) is a development-stage company engaged in the discovery and development of Galectin-targeting therapeutics that are intended to reduce toxicity and improve the efficacy of chemotherapy drugs by combining the drugs with proprietary compounds. These compounds also may have application for drugs to treat other diseases and chronic health conditions.

The Company is devoting substantially all of its efforts toward product research and development and raising capital. In May 2008, the Company submitted a Drug Master File (“DMF”) for the Company’s lead product DAVANAT^® to the FDA. The DMF contains confidential detailed information in support of a New Drug Application (“NDA”) about facilities, processes or articles used in the manufacturing, processing, packaging, and storing or stability of drugs.

In September 2008, the Company submitted a clinical and pre-clinical package to the Food and Drug Administration (“FDA”) in support of the Company’s DAVANAT^® NDA. The FDA reported to the Company in its minutes for the December 2008 meeting that the Company will be required to conduct a Phase III trial to demonstrate superiority to the best standard of care for colorectal cancer patients.

On December 17, 2010, Company executives met with officials from the FDA to present its Phase III clinical development program for DAVANAT^®. Agreement was reached on the design of pivotal, randomized, controlled, and blinded Phase III clinical trials of DAVANAT^® co-administered with standard chemotherapy for second line treatment of patients with metastatic colorectal cancer.

As shown in the consolidated financial statements, the Company incurred cumulative net losses applicable to common stockholders of $56.7 million for the cumulative period from inception (July 10, 2000) through December 31, 2010. The Company’s net losses have resulted principally from costs associated with (i) research and development expenses, including clinical trial costs, (ii) general and administrative activities and (iii) the Company’s financing transactions including interest, dividend payments, and the costs related to fair value accounting for the Company’s convertible debt instruments. As a result of planned expenditures for future research, discovery, development and commercialization activities and potential legal cost to protect its intellectual property, the Company expects to incur additional losses and use additional cash in its operations for the foreseeable future. Through December 31, 2010, the Company had raised a net total of $52.2 million in capital through sale and issuance of common stock, common stock purchase warrants, convertible preferred stock and debt securities in public and private offerings. From inception (July 10, 2000) through December 31, 2010, the Company used cash of $45.4 million in its operations.

At December 31, 2010, the Company had $5,891,000 of unrestricted cash and cash equivalents available to fund future operations. Subsequent to December 31, 2010, the Company issued 3,757,472 shares of common stock for the exercise of common stock warrants and options, resulting in net cash proceeds of $2,209,000 and 13 shares of Series C preferred stock for net cash proceeds of $130,000. Subsequent to year end, the Company also received $235,000 due under a research grant (a Qualifying Therapeutic Discovery Project (“QTDP”) Program). The Company believes that with the cash and cash equivalents on hand at December 31, 2010 and the funds received subsequent to December 31, 2010, there is sufficient cash to fund operations into the second half of 2012. The Company is actively seeking to raise additional capital. If the Company is unsuccessful in raising additional capital or is unsuccessful in bringing its products to market before the end of the second quarter of 2012, the Company may be required to cease operations or seek bankruptcy protection.

F-15

On January 9, 2009, the Company was delisted from the NYSE Alternext US (“Exchange”), formerly the American Stock Exchange, due to non-compliance with the Exchange minimum shareholders’ equity requirements. On January 21, 2009, the Company began trading on the Over-the-Counter Bulletin Board (“OTCBB”) under the symbol PRWP.OB.

The Company is subject to a number of risks similar to those of other development-stage companies, including dependence on key individuals, uncertainty of product development and generation of revenues, dependence on outside sources of capital, risks associated with clinical trials of products, dependence on third-party collaborators for research operations, need for regulatory approval of products, risks associated with protection of intellectual property, and competition with larger, better-capitalized companies. Successful completion of the Company’s development program and, ultimately, the attainment of profitable operations is dependent upon future events, including obtaining adequate financing to fulfill its development activities and achieving a level of revenues adequate to support the Company’s cost structure. There are no assurances that the Company will be able to obtain additional financing on favorable terms, or at all or successfully market its products.

2.	Summary of Significant Accounting Policies

The accompanying consolidated financial statements reflect the application of certain accounting policies, as described in this note and elsewhere in the accompanying notes to financial statements.

Basis of Consolidation. The consolidated financial statements include the accounts of the Company, Pro-Pharmaceuticals Securities Corp., its wholly-owned subsidiary, which was incorporated in Delaware on December 23, 2003, and Medi-Pharmaceuticals, Inc., its wholly-owned subsidiary, which was incorporated in Nevada on August 17, 2010. Pro-Pharmaceuticals Securities Corp. holds the cash and cash equivalents that are not required to fund current operating needs. Medi-Pharmaceuticals, Inc. was formed for the development of technology in cardiovascular treatments. All intercompany transactions have been eliminated.

Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses and disclosure of contingent assets and liabilities. Management’s estimates and judgments include assumptions used in stock option and warrant liability valuations, useful lives of property and equipment and intangible assets, accrued liabilities, deferred income taxes and various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from those estimates.

Cash and Cash Equivalents. The Company considers all highly-liquid investments with original maturities of 90 days or less at the time of acquisition to be cash equivalents.

Prepaid Expenses and Other Current Assets. Deposits and other assets consist principally of prepaid insurance and prepaid rent on the Company’s leased executive office space.

Property and Equipment. Property and equipment, including leasehold improvements, are stated at cost, net of accumulated depreciation, and are depreciated using the straight-line method over the estimated useful lives of the related assets of generally three years for computers and office equipment, five years for furniture and fixtures and the shorter of the useful life or life of the lease for leasehold improvements.

Restricted Cash. Restricted cash consists of security deposits principally for a real estate lease.

Intangible Assets. Intangible assets include patent costs, consisting primarily of related legal fees, which are capitalized and amortized over an estimated useful life of five years from issuance. Amortization expense in 2010 and 2009 was $2,000 and $14,000, respectively. Gross intangible assets at December 31, 2010 and 2009 totaled $78,000 and $93,000, respectively, and accumulated amortization at December 31,

F-16

2010 and 2009 totaled $39,000 and $37,000, respectively. The Company recorded an impairment charge related to capitalized patent costs of $15,000 and $155,000 in 2010 and 2009, respectively, which is included in general and administrative expense in the consolidated statements of operations, when it was determined that the underlying intellectual property would have no future benefit to the Company.

Long-Lived Assets. The Company reviews all long-lived assets for impairment whenever events or circumstances indicate the carrying amount of such assets may not be recoverable. Recoverability of assets to be held or used is measured by comparison of the carrying value of the asset to the future undiscounted net cash flows expected to be generated by the asset. If such asset is considered to be impaired, the impairment recognized is measured by the amount by which the carrying value of the asset exceeds the discounted future cash flows expected to be generated by the asset.

Warrants. The Company has issued common stock warrants in connection with the execution of certain equity and debt financings. Certain warrants are accounted for as derivative liabilities at fair value. Such warrants do not meet the accounting criteria that a contract should not be considered a derivative instrument if it is (1) indexed to its own stock and (2) classified in stockholders’ equity. Changes in fair value of derivative liabilities are recorded in the consolidated statement of operations under the caption “Change in fair value of warrant liabilities.” Warrants that are not considered derivative liabilities are accounted for at fair value at the date of issuance in additional paid-in capital. The fair value of warrants is determined using the Black-Scholes option-pricing model.

Revenue Recognition. The Company records revenue provided that there is persuasive evidence that an arrangement exists, the price is fixed and determinable, services were rendered and collectibility is reasonably assured.

Income Taxes. The Company accounts for income taxes in accordance with the accounting rules that requires an asset and liability approach to accounting for income taxes based upon the future expected values of the related assets and liabilities. Deferred income tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities and for tax loss and credit carry forwards, and are measured using the expected tax rates estimated to be in effect when such basis differences reverse. Valuation allowances are established, if necessary, to reduce the deferred tax asset to the amount that will, more likely than not, be realized.

Comprehensive Income (Loss). Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. The Company does not have any items of comprehensive income (loss) other than net losses as reported.

Fair Value of Financial Instruments. The Company’s financial instruments consist of cash equivalents, accounts payable and accrued expenses. The estimated fair value of these financial instruments approximates their carrying value due to their short-term nature. Additionally, certain common stock warrants are recorded as liabilities at fair value. In September 2006, the Financial Accounting Standards Board (“FASB”) issued rules, which were adopted by the Company in the first quarter of fiscal year 2008, which clarified the principle that fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. Under the standard, fair value measurements are separately disclosed by level within the fair value hierarchy. See Note 9.

F-17

Concentration of Credit Risk . Financial instruments that subject the Company to credit risk consist of cash and cash equivalents and certificates of deposit. The Company maintains cash and cash equivalents and certificates of deposit with well-capitalized financial institutions. At times, those amounts may exceed federally insured limits. The Company has no significant concentrations of credit risk.

Stock-Based Compensation. Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the service period, which generally represents the vesting period. For awards that have performance based vesting conditions the Company recognizes the expense over the estimated period that the awards are expected to be earned. The Company uses the Black-Scholes option-pricing model to calculate the grant date fair value of stock options. The expense recognized over the service period is required to include an estimate of the awards that will be forfeited.

Recent Accounting Pronouncements

In January 2010, the FASB issued Accounting Standards Update (“ASU”) No. 2010-06 for Fair Value Measurements and Disclosures (Topic 820): Improving Disclosures about Fair Value Measurements. This Update requires new disclosures for transfers in and out of Level 1 and 2 and activity in Level 3. This Update also clarifies existing disclosures for level of disaggregation and requires additional disclosures about inputs and valuation techniques. The new disclosures are effective for interim and annual periods beginning after December 15, 2009, except for the Level 3 disclosures, which are effective for fiscal years beginning after December 15, 2010 and for interim periods within those years. Other than requiring additional disclosures, adoption of this new guidance did not have a material impact on the Company’s financial statements and is not expected to have a significant impact on the reporting of the Company’s financial condition or results of operations.

3.	Agreement with PROCAPS S.A. and Research Grants

Agreement with PROCAPS S.A.

On March 25, 2010, the Company granted PROCAPS S.A. (“PROCAPS”) exclusive rights to market and sell DAVANAT^® to treat cancer in Colombia, South America. PROCAPS is a large, international, privately held pharmaceutical company based in Barranquilla, Colombia. Under terms of the agreement, PROCAPS is responsible for obtaining regulatory and pricing approval in Colombia, South America. PROCAPS also will be responsible for the vial filling, packaging, marketing and distribution of DAVANAT^® in the region.

Once approved for sale by regulators, the Company will receive a transfer payment for each dose of DAVANAT^® shipped to PROCAPS, in addition to a royalty above a minimum annual sales threshold. In October 2010, the Company received a payment of $200,000 and shipped DAVANAT^® to PROCAPS to be used by PROCAPS to qualify its vial filling process and to replicate the Company’s stability study. The Company retains all intellectual property rights and is the owner of the regulatory approval of DAVANAT^®

F-18

in the region. PROCAPS has first negotiation rights to other countries in South and Central America and the Caribbean. Should we gain approval in Colombia, PROCAPS may then obtain the marketing authorization in more than 10 countries in Latin America.

The Company recorded the $200,000 payment from PROCAPS as deferred revenue on the consolidated balance sheet as of December 31, 2010 and will recognize the revenue when the remaining deliverables of the collaboration agreement have been completed.

Qualifying Therapeutic Discovery Project

In October 2010, the Company was notified that it was awarded $489,000 total in two federal grants under the Qualifying Therapeutic Discovery Project (“QTDP”) Program for its DAVANAT anti-cancer compound and for its GR/GM-Series of anti-fibrotic, cirrhosis compounds for work performed during 2010 and 2009.

Such offering costs were netted against the proceeds of the 2002 Private Placement.

F-22

beginning on August 25, 2008. The warrants provide for cashless exercise if at any time during the term of the warrants if there is no effective registration statement for the issuance or resale of the underlying warrant shares. The exercise price of each warrant is adjustable in the event of a stock split or stock combination, capital reorganization, merger or similar event. On December 26, 2008, the 3,000,000 warrants exercisable at $0.63 expired unexercised.

The Company received proceeds of $3,381,000, net of cash transaction costs of $369,000. In addition the Company incurred $56,000 of costs for warrants issued to a placement agent. Proceeds of $1,044,000 were allocated to common stock and $2,281,000 were allocated to investor warrants using the Black-Scholes method with a fair market value of the Company’s common stock of $0.40 and the following assumptions as of February 25, 2008: for the 5 year warrants exercisable at $0.70, a risk-free interest rate of 2.94% and volatility of 95% and for the 4 month warrants exercisable at $0.63, a risk-free interest rate of 2.13% and volatility of 95%. The warrants were determined to have the characteristics of derivative liabilities and were originally accounted for as liabilities prior to the Company increasing the authorized number of shares. Changes in fair value were recognized as either a gain or loss in the consolidated statement of operations. In the second quarter of 2008 the warrants were reclassified to equity. Through May 21, 2008, these warrants were marked to market resulting in a reduction in warrant liabilities in the balance sheet and an offsetting credit to change in fair value of warrant liabilities in the statement of operations in the amount of $356,000. The remaining fair value of $2,160,000 was credited to additional paid-in capital in the balance sheet. On December 26, 2008 the 3,000,000 warrants exercisable at $0.63 expired unexercised. If the Company pays a stock dividend or makes a distribution or combines shares of its common stock, then the number of shares issuable upon exercise of this warrant shall be proportionately adjusted such that the aggregate exercise price of this warrant remains unchanged. On July 2, 2008, the Company issued 300,000 warrants to Cork Investments in exchange for $20,000. The warrants are exercisable for common stock at $1.00 per share for a period of three years. The $20,000 was credited to additional paid in capital.

Series A 12% Convertible Preferred Stock – February 4, 2008 Private Placement

On February 4, 2008, the Company closed a private placement begun in October 2007 of its Series A 12% Convertible Preferred Stock (“Series A”) and related warrants. In this transaction, the Company sold units of securities at $1.00 per unit, each unit comprised of (i) one share of Series A Preferred, (ii) a warrant to purchase one share of common stock for $1.50, and (iii) a warrant to purchase one share of common stock for $2.00. Each share of the Series A is entitled to dividends at the rate of 12% per annum payable at the Company’s option in cash or shares of common stock valued at the higher of $1.00 per share or 100% of the value weighted average price of the Company’s share price for the 20 consecutive trading days prior to the applicable dividend payment date. Dividends are payable semi-annually on March 30 and September 30. The dividend paid on the initial dividend payment date is calculated from the date the Company deposited each subscription advance. During 2010 and 2009, the Company recorded dividends of $192,000 and $209,000, respectively, and issued 196,086 and 209,100 shares of common stock, respectively, for dividend payments.

The shares of Series A are entitled to vote as a class with the Company’s common stock and each share of Series A is convertible at any time to one share of common stock, subject to adjustment in the event of a stock dividend, stock split or combination, reclassification or similar event. The Company has the right to require conversion if the closing price of the common stock exceeds $3.00 for 15 consecutive trading days and a registration statement covering the resale of the shares of common stock issuable upon conversion of the Series A is then in effect. Each warrant is exercisable solely for cash beginning August 3, 2008 and expires on February 4, 2012. The exercise price of each warrant is adjustable in the event of a stock split or stock combination, capital reorganization, merger or similar event.

As of December 31, 2007, the Company had received subscription advances of $1,667,500 for Series A. In 2008, the Company received additional subscription advances of $75,000 resulting in total gross proceeds of $1,742,500. On February 4, 2008 the Company closed the private placement. The Company incurred

F-23

$52,000 of cash transaction costs resulting in net cash proceeds of $1,691,000. In addition, the Company incurred $3,000 of costs for 8,400 warrants exercisable at $1.50 issued to placement agents. Proceeds of $984,000 were allocated to investor warrants using the Black-Scholes method with the following assumptions as of February 4, 2008: risk free interest rate 2.51%, volatility 95%, fair market value of the company’s common stock on February 4, 2008, and the share price on the closing date of the transaction of $0.59. The warrants were originally accounted for as freestanding derivative instruments in the consolidated balance sheet formerly under the caption “Warrant Liabilities”. These warrants were originally classified as a liability because the February 2006 warrants contain an anti-dilution provision in the event of a subsequent dilutive issuance and the potential number of shares issuable exceeded the Company’s authorized shares. Changes in fair value were recognized as either a gain or loss in the consolidated statement of operations under the caption “Change in fair value of warrant liabilities”. In the second quarter of 2008, the warrants were reclassified to equity as a result of an amendment to the Company’s articles of incorporation approved at the May 21, 2008 annual meeting of shareholders increasing the Company’s authorized common. Through May 21, 2008, these warrants were marked to market resulting in a reduction in warrant liabilities in the balance sheet and an offsetting credit to change in fair value of warrant liabilities in the statement of operations in the amount of $100,000. The remaining fair value of $502,000 was credited to additional paid-in capital in the balance sheet.

Upon notice of not less than 30 trading days, a holder of Series B may require the Company to redeem, in whole or in part at any time on or after the earlier of (a) February 12, 2019 or (b) the date of issuance of a promissory note to David Platt in connection with the achievement of certain milestones under his separation agreement (as amended on January 21, 2011, see Notes 12 and 14 for further details). The redemption price will be equal to the sum of the stated value of the Series B, plus all accrued but unpaid dividends thereon, as of the redemption date. If the Company fails to pay the redemption price in cash on the redemption date, then the holders of the Series B requesting redemption may, at their sole option, automatically convert their shares of Series B into a promissory note bearing interest at the rate of 15% per year and secured by a lien on all of the Company’s assets. So long as any shares of the Series B remain outstanding, the Company is also subject to restrictions limiting, among other things, amendments to the Company’s organizational documents; the purchase or redemption of the Company’s capital stock; mergers, consolidations, liquidations and dissolutions; sales of assets; dividends and other restricted payments; investments and acquisitions; joint ventures, licensing agreements, exclusive marketing and other distribution agreements; issuances of securities; incurrence of indebtedness; incurrence of liens and other encumbrances and issuances of any common stock equivalents.

Voting Rights. Except as noted below, the holder of each share of Series B shall be entitled to the number of votes equal to the number of shares of Common Stock into which such share of Series B would be convertible, and shall otherwise have voting rights and powers equal to the voting rights and powers of the Common Stock. With respect to the election of directors, the holders of the Series B shall vote together as a separate class to elect two (2) members of the Board of Directors (the “Series B Directors”), and the Company shall take all reasonably necessary or desirable actions within its control (including, without limitation, calling special meetings of the Board of Directors, nominating such persons designated by the holders of the Series B as directors on the applicable proxy statements and recommending their election) to permit the holders of the Series B to appoint two additional (2) members of the Board of Directors (the “Series B Nominees”), who shall be subject to election by all shares of voting stock of the Company voting together as a single group, until such time as all authorized shares of Series B have has been issued and sold, after which the number of Series B Nominees shall be three (3), and shall remain three (3) until there are no longer any shares of Series B outstanding. The holders of Series B shall vote together with the holders of Common Stock and other voting capital stock of the Company to elect all other members of the Board of Directors.

Other Restrictions. So long as any shares of the Series B remain outstanding, the Company may not, without the approval of the holders of a majority of the shares of Series B outstanding, among other things, (i) change the size of the Company’s Board of Directors; (ii) amend or repeal the Company’s Articles of Incorporation or Bylaws or file any articles of amendment designating the preferences, limitations and relative rights of any series of preferred stock; (iii) create or increase the authorized amount of any

additional class or series of shares of stock that is equal to or senior to Series B; (iv) increase or decrease the authorized number of shares of the Series B; (v) purchase, redeem or otherwise acquire for value any shares of any class of capital stock; (vi) merge or consolidate the Company into or with any other corporation or sell, assign, lease, pledge, encumber or otherwise dispose of all or substantially all of the Company’s assets or those of any subsidiary; (vii) voluntarily or involuntarily liquidate, dissolve or wind up the Company or the Company’s business; (viii) pay or declare dividends on any capital stock other than the Preferred Stock, unless the Series B share ratably in such dividend and all accrued dividends payable with respect to the Series B have been paid prior to the payment or declaration of such dividend; (ix) acquire an equitable interest in, or the assets or business of any other entity in any form of transaction; (x) create or commit us to enter into a joint venture, licensing agreement or exclusive marketing or other distribution agreement with respect to the Company’s products, other than in the ordinary course of business; (xi) permit the Company or any subsidiary to sell or issue any security of such subsidiary to any person or entity other than the Company; (xii) enter into, create, incur, assume or guarantee any indebtedness for borrowed money of any kind (other than indebtedness existing on the initial closing date and approved by Series B shareholders); (xiii) enter into, create, incur or assume any liens of any kind (other than certain permitted liens); (xiv) issue any common stock equivalents; (xv) increase the number of shares of the Company’s common stock that may be issued pursuant to options, warrants or rights to employees, directors, officers, consultants or advisors above 1,500,000.

Warrants. Each Class A-1 warrant, Class A-2 warrant and Class B warrant is exercisable at $0.50 per share of common stock at any time on or after the date of issuance until the fifth anniversary of the respective issue date. The Company may, upon 30 days notice and so long as an effective registration statement regarding the underlying shares of common stock is in effect, issue a termination notice with respect to (i) each Class A-1 warrant on any trading day on which the market value of the common stock for each of the 15 previous trading days exceeded $1.25 per share and (ii) each Class A-2 warrant on any trading day on which the market value of the common stock for each of the 15 previous trading days exceeded $1.75 per share.

The fair value of the warrants issued in connection with the Series B-1 was $1,296,000 at the date of issuance based on the following assumptions: an expected life of 5 years, volatility of 118%, risk free interest rate of 1.79% and zero dividends. The Company allocated the gross proceeds based on the relative fair value of the Series B-1 and the related warrants, resulting in $1,105,000 of the proceeds being allocated to additional paid-in capital. The Company analyzed the Series B-1, post-allocation of the gross proceeds, and determined that there was no beneficial conversion feature at the date of issuance. The issuance costs of the Series B-1 and the amounts allocated to warrants were recorded as a reduction to the carrying value of the Series B-1 when issued, and are accreted to the redemption value of the Series B-1 through the earliest redemption date. Due to the redemption feature, the Company has presented the Series B-1 outside of permanent equity, in the mezzanine of the consolidated balance sheet at December 31, 2010 and 2009.

The fair value of the warrants issued during the year ended December 31, 2010 in connection with the Series B-2 was $4,148,000 at the dates of issuance based on the following assumptions: an expected life of 5 years, volatility of 126% to 129%, risk free interest rates of 2.27% to 2.43% and zero dividends. The fair value of the warrants issued during the year ended December 31, 2009 in connection with the Series B-2 was $5,333,000 at the dates of issuance based on the following assumptions: an expected life of 5 years, volatility of 124% to 127%, risk free interest rates of 1.98% to 2.70% and zero dividends. The Company allocated the gross proceeds based on the relative fair value of the Series B-2 and the related warrants, resulting in $1,028,000 and $1,732,000 of the proceeds being allocated to additional paid-in capital for the years ended December 31, 2010 and 2009, respectively. The issuance costs of the Series B-2 and the amounts allocated to warrants were recorded as a reduction to the carrying value of the Series B-2 when issued, and are accreted to the redemption value of the Series B-2 through the earliest redemption dates. Due to the redemption feature, the Company has presented the Series B-2 outside of permanent equity, in the mezzanine of the consolidated balance sheet at December 31, 2010 and 2009.

F-27

The Company analyzed the Series B-2, post-allocation of the gross proceeds, and determined that there was a beneficial conversion feature at the dates of issuance. Because the closing price of the common stock on the closing date was greater than the effective conversion price, $388,000 and $628,000 of the proceeds (limited to the allocation of the proceeds) during the years ended December 31, 2010 and 2009, respectively, were allocated to an embedded beneficial conversion feature of the Series B-2. The amount allocated to the beneficial conversion feature was recorded as a discount to the Series B-2 is being accreted, with such accretion being charged through the earliest redemption dates.

Series C 6% Super Dividend Convertible Preferred Stock

On December 29, 2010, the Company designated and authorized the sale and issuance of up to 1,000 shares of Series C Super Dividend Convertible Preferred Stock (“Series C”) with a par value of $0.01 and a stated value equal to $10,000 (the “Stated Value”).

On December 30, 2010, the Company sold and issued 212 shares of Series C at a price of $10,000 per share for gross proceeds of $2,120,000. The Company incurred $47,000 of cash transaction costs resulting in net cash proceeds of $2,073,000. In addition, the Company issued 3,000 warrants exercisable at $1.20 to a placement agent which had a de minimis value.

The terms of the Series C are as follows:

Conversion Rights. Each holder of Series C may convert all, but not less than all, of his Series C shares plus accrued and unpaid dividends into Common Stock at the price of $1.00 per share of Common Stock (“Conversion Price”), such that 10,000 shares of Common Stock will be issued per each converted share of Series C (accrued and unpaid dividends will be issued as additional shares).

Subject to the continuing obligation to pay post conversion dividends, the Company may convert all, but not less than all, of the Series C (plus all accrued and unpaid dividends) into Common Stock, at the Conversion Price, upon such time that the closing price of the Common Stock is no less than $3.00 per share for 15 consecutive trading days.

Dividends. Holders of Series C shall be entitled to receive cumulative non-compounding dividends at the rate per share of Series C equal to the greater of (i) 6% per annum of the Stated Value (also defined as the “Floor”) or (ii) the product of (A) the Applicable Percentage (defined below) of net sales of the Company’s DAVANAT^® product generated during the applicable dividend period multiplied by (B), the fraction of (I) one (1) divided by (II) the sum of the total number of shares of Series C issued and outstanding on the dividend payment date plus the total number of Series C Post Conversion Dividend Rights issued and outstanding on the dividend payment date. Applicable Percentage means, as to each share of Series C, 2.5% (0.53% based on 212 shares issued and outstanding at December 31, 2010) until total dividends are equal to the total investment in the shares of the Series C, and 1.25% (0.265% based on 212 shares issued and outstanding at December 31, 2010) thereafter. The maximum amount each Series C shareholder will receive in dividend payments is equal to $100,000 (the “Maximum Payout”). For purposes of this dividend calculation, net sales shall mean gross revenues actually received by the Company, from the sale or licensing of the product DANAVAT^®, less chargebacks, returns, expenses attributable to product recalls, duties, customs, sales tax, freight, insurance, shipping expenses, allowances and other customary deductions.

The dividend shall be payable in arrears semi annually on March 31 and September 30, beginning with the first such date after the original issue date; provided, however, that all dividends and all other distributions shall cease, and no further dividends or other distributions shall be paid, in respect of each share of Series C from and after such time that the Maximum Payout has been paid in respect of such share of Series C. Such dividends shall be payable at the Company’s option either in cash or in duly authorized, fully paid and non-assessable shares of Common Stock valued at the higher of (i) $0.50 per share or (ii) the average of the Common Stock trading price for the ten (10) consecutive trading days ending on the trading day that is immediately prior to the dividend payment date.

F-28

Series C Post Conversion Dividend Right. In the event that any share of Series C is converted into Common Stock before the Maximum Payout is paid in respect of such converted share of Series C, then the holder shall have the right to continue to receive dividends in respect of such converted share of Series C equal to the remaining payout (the “Series C Preferred Stock Post Conversion Dividend Right”) which shall be equal to the Maximum Payout less the cumulative dividends received through the conversion date. One share of Series C Preferred Stock Post Conversion Dividend Right shall be issued for each such converted share of Series C. The holder of each Series C Preferred Stock Post Conversion Dividend Right shall receive the remaining payout on an equal basis and in conjunction with the then outstanding shares of Series C and all the other then outstanding Series C Post Conversion Dividend Rights, in the same manner and subject to the same terms and conditions as applicable to the payment of dividends on each share of Series C, except that for purposes of calculating the dividend the Floor shall not apply. The Series C Preferred Stock Post Conversion Dividend Right shall have no stated value, liquidation preference or right to any dividends or distributions other than the remaining payout. The Series C Preferred Stock Post Conversion Right is subject to redemption in the same manner as outstanding Series C shares.

At the date of issuance, the Series C have an embedded dividend right to continue to receive dividend payments after conversion to common stock (the Series C Post Conversion Dividend Right) which requires bifurcation. The value of this post conversion dividend right on the date of issuance was determined to be de minimis due to the payment of a dividend stream other than the 6% dividend and conversion of Series C prior to the Company achieving sales of DANAVAT^® was deemed improbable at that time. Upon a conversion of the Series C, the Company will be required to record a liability and the related expense during the period of conversion. The Company will continue to evaluate and assess the Series C Post Conversion Dividend Right for each reporting period.

Liquidation Rights. In the event of any liquidation, dissolution or winding up of the Company, either voluntarily or involuntarily, the holders of Series C will receive $10,000 per share plus accrued and unpaid dividends, payable prior and in preference to any distributions to the holders of Common Stock but after and subordinate to the Series A, Series B-1 and Series B-2, subject to the Maximum Payout.

Redemption. Upon a sale of the Company, the Company shall redeem all of the then outstanding shares of Series C and Series C Preferred Stock Post Conversion Rights within thirty (30) days after the transaction constituting the sale of the Corporation is closed and such closing is fully funded. The price to redeem a share of Series C and each redeemed Series C Preferred Stock Post Conversion Redemption Right shall be equal to (i) (A) the applicable return on investment (“ROI”) percentage, multiplied by (B) $10,000, minus (ii) the cumulative dividends received through the redemption date. The Redemption Price shall be payable at our option either in cash or in shares of common stock valued at the higher of (i) $0.50 per share or (ii) the average market price for the ten consecutive trading days ending immediately prior to the date of redemption. The ROI Percentage shall mean the percentage that applies as of the redemption date, as follows:



ROI Percentage

200%		before the second anniversary of the date of issuance;
250%		on or after the second anniversary of the date of issuance, but before the third anniversary of the date of issuance;
300%		on or after the third anniversary of the date of issuance, but before the fourth anniversary of the date of issuance;
350%		on or after the fourth anniversary of the date of issuance, but before the fifth anniversary of the date of issuance;
400%		on or after the fifth anniversary of the date of issuance, but before the sixth anniversary of the date of issuance;
450%		on or after the sixth anniversary of the date of issuance, but before the seventh anniversary of the date of issuance;
500%		on or after the seventh anniversary of the date of issuance, but before the eighth anniversary of the date of issuance; and
550%		on or after the eighth anniversary of the date of issuance, but before the ninth anniversary of the date of issuance.

F-29

Due to the redemption feature, the Company has presented the Series C outside of permanent equity, in the mezzanine of the consolidated balance sheet at December 31, 2010.

Voting Rights. The Series C shares have no voting rights.

The exercise price of the warrants has been adjusted from $3.35 per share to $0.50 per share and an additional 2,548,430 shares of the Company’s common stock are issuable upon exercise of the warrants due to subsequent issuance of equity related instruments. The warrants were classified as equity at December 31, 2008 but have been reclassified as warrant liabilities as a result of the adoption of new accounting provisions on January 1, 2009 that require warrants with certain features to be accounted for as a liability. See Note 9.

Consultant Warrants

In May 2008 the Company entered into an agreement with Investor Relations Group (“IRG”) for IRG to provide investor relations services to the Company in exchange for cash and warrants on a monthly basis. On September 30, 2008 the Company terminated the agreement under the provisions of the agreement. During the effective contract period IRG earned 39,000 warrants valued at $3,000. The expense associated with these warrants was calculated using the Black-Scholes option-pricing model and charged to stock compensation expense. The warrants are exercisable at $0.50 per share for a period of three years.

In April 2009, the Company entered into agreements with consultants that provided for the grant of warrants for the purchase of 330,000 shares of common stock at an exercise price of $0.50 per share. Of the 330,000 warrants, 80,000 vested immediately and 250,000 will vest upon the achievement of certain milestones. The initial 80,000 warrants were valued at $32,000 on issuance based on the following assumptions: an expected life of 4 years, volatility of 134%, risk free interest rate of 1.76% and zero dividends and the expense recognized upon issuance. During the year ended December 31, 2010, 50,000 warrants vested (valued at $16,000 on the vesting date using the following assumptions: expected life of 3.06 years, volatility of 140%, risk free interest rates of 1.69% and zero dividends). When it became probable that the remaining 200,000 warrants would vest, the Company valued the warrants at $124,000 as of December 31, 2010 using the following assumptions: expected life of 2.29 years, volatility of 141%, risk free interest rates of 0.61% and zero dividends. The Company recognized expense related to the 200,000 warrants of $111,000 for the year ended December 31, 2010.

In May 2009, the Company entered into agreements with consultants that provided for the grant of warrants to purchase 575,000 shares of common stock at an exercise price of $0.50 per share. The warrants were valued at $232,000 on issuance based on the following assumptions: an expected life of 5 years, volatility of 124%, risk free interest rate of 2.16% and zero dividends. The Company recognized expense related to these warrants of $53,000 and $122,000 during the years ended December 31, 2010 and 2009, respectively. As of December 31, 2010, 444,000 of these warrants were vested and 131,000 shares were forfeited. The agreements also provide for the issuance of additional warrants to purchase up to 150,000 shares of common stock based on the achievement of certain milestones. The Company will value and account for these potential warrants when it is determined that it is probable the milestones will be achieved.

Impact of Adopting Provisions Regarding Warrant Liabilities

In June 2008, the Financial Accounting Standards Board (“FASB”) ratified standards related to determining whether an instrument (or an embedded feature) is indexed to an entity’s own stock. The standards provide that an entity should use a two step approach to evaluate whether an equity-linked financial instrument (or embedded feature) is indexed to its own stock, including evaluating the instrument’s contingent exercise and settlement provisions. The standard is effective for fiscal years beginning after December 15, 2008. The Company adopted the standard on January 1, 2009 and determined that the 6,989,574 warrants issued in connection with the February 2006 Transaction that had been classified as equity and included in additional paid-in capital at December 31, 2008, should be classified as liabilities due to repricing and anti-dilution provisions contained in the warrant agreements. The impact of adopting new accounting provisions on January 1, 2009, which required the treatment of warrants with certain features as liabilities rather than equity, was a decrease in additional paid-in-capital by $458,000, which was the fair value recorded at the time the warrants were transferred from a liability to equity during the year ended December 31, 2008, an increase of warrant liabilities by $204,000, the fair value of the warrants as of January 1, 2009 and a credit to accumulated deficit for the difference.

During the years ended December 31, 2010 and 2009, the Company recognized a loss of $1,241,000 and $1,374,000, respectively in its condensed consolidated statements of operations related to the change in fair value of warrant liabilities.

9.	Fair Value of Financial Instruments

In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs utilize data points that are observable, such as quoted prices, interest rates and yield curves. Fair values determined by Level 3 inputs utilize unobservable data points for the asset or liability. A majority of the Company’s financial liabilities have been classified as Level 2. These Level 2 liabilities consist of warrant liabilities and have been valued using the Black-Scholes pricing model. The fair values of our money markets (cash equivalents), are readily determinable and have therefore been classified as Level 1 assets. The Company assesses the levels of its financial instruments at each measurement date, and transfers between levels are recognized on the actual date of the event or change in circumstances that caused the transfer in accordance with the Company’s accounting policy regarding the recognition of transfers between levels of the fair value hierarchy.

The Company uses the Black-Scholes pricing model to calculate fair value of its warrant liabilities. The Company considered using methods of valuation other than Black-Scholes for the year ended December 31, 2010, but due to the short term nature of these instruments, which expire in August 2011, the Company determined that using a different valuation method would not likely result in a materially different valuation. Key assumptions used to apply these models are as follows:


	December 31,
	2010			2009
Risk free interest rate		0.19	%		1.14	%
Expected life		0.62 years			1.62 years
Expected volatility of common share price		70	%		156	%
Common share price	$	0.90		$	0.28

F-34

Below is a summary of our fair value measurements at December 31, 2010 and 2009:


	Value at year end		Quoted prices in active markets (Level 1)		Significant other observable inputs (Level 2)		Significant unobservable inputs (Level 3)
	(in thousands)
Year ended December 31, 2010:
Warrant liabilities	$	861	$	—	$	861	$	—
Year ended December 31, 2009:
Warrant liabilities	$	1,633	$	—	$	1,633	$	—

There were no transfers between level 1, 2 or 3 during the years ended December 31, 2010 and 2009.

A summary of changes in the Warrant Liabilities is as follows:


	Fair Value of Warrant Liabilities
	(in thousands)
Balance January 1, 2009	$	55

Cumulative effect of change in accounting policy		204
Change in fair value of warrant liabilities		1,374

Balance December 31, 2009	$	1,633

Change in fair value of warrant liabilities		1,241
Intrinsic value of liability warrants exercised		(2,013	)

Balance December 31, 2010	$	861

The Company’s financial instruments consist of cash equivalents, accounts payable and accrued expenses. The estimated fair value of these financial instruments approximates their carrying value due to their short-term nature.

Stock-Based Compensation

Summary of Stock-Based Compensation Plans

At December 31, 2010, the Company had three stock-based compensation plans where the Company’s common stock has been made available for equity-based incentive grants as part of the Company’s compensation programs (the “Plans”) as follows:

2001 Stock Incentive Plan. In October 2001, the Company’s Board of Directors adopted the Pro-Pharmaceuticals, Inc. 2001 Stock Incentive Plan (the “Incentive Plan”), which permits awards of incentive and nonqualified stock options and other forms of incentive compensation to employees and non-employees such as directors and consultants. The Board has 5,000,000 shares of common stock for issuance upon exercise of grants made under the Incentive Plan. Options granted under the Incentive Plan vest either immediately or over a period of up to three years, and expire 3 years to 10 years from the grant date. At December 31, 2010, 125,000 shares were available for future grant under the Incentive Plan.

2003 Non-Employee Director Stock Option Plan. In 2003, the stockholders approved the Pro-Pharmaceuticals, Inc. 2003 Non-Employee Director Stock Option Plan (the “Director Plan”), which permits awards of stock options to non-employee directors. The stockholders reserved 1,000,000 shares of common stock for issuance upon exercise of grants made under the Director Plan. At December 31, 2010, 801,000 shares were available for future grant under the Director Plan.

2009 Incentive Compensation Plan. In February 2009, the Company adopted the 2009 Incentive Compensation Plan (the “2009 Plan”) which provides for the issuance of up to 10,000,000 shares of the

F-35

Company’s common stock in the form of options, stock appreciation rights, restricted stock and other stock-based awards to employees, officers, directors, consultants and other eligible persons. At December 31, 2010, 360,000 shares were available for future grant under the 2009 Plan.

In addition, the Company has awarded 464,604 non-plan stock option grants to non-employees. These non-plan grants have vesting periods and expiration dates similar to those options granted under the Incentive Plan. At December 31, 2010, 364,250 non-plan grants were outstanding.

Stock-based compensation expense, including restricted stock, totaled $1,281,000 and $1,610,000 in 2010 and 2009, respectively. The Company expenses the value of stock options as earned. The fair value of the options granted is determined using the Black-Scholes option-pricing model. The following weighted average assumptions were used:


	2010			2009			Cumulative Period from Inception (July 10, 2000) to December 31, 2010
Risk-free interest rate		2.38	%		2.0	%		2.44	%
Expected life of the options		5 years			5 years			5 years
Expected volatility of the underlying stock		126	%		122	%		112	%
Expected dividend rate		0	%		0	%		0	%

As noted above, the fair value of stock options is determined by using the Black-Scholes option pricing model. For all options granted since January 1, 2006 the Company has generally used option terms of between 5 to 7 years, with 5 years representing the estimated life of options granted. The volatility of the common stock is estimated using historical volatility over a period equal to the expected life at the date of grant. The risk-free interest rate used in the Black-Scholes option pricing model is determined by reference to historical U.S. Treasury constant maturity rates with terms equal to the expected terms of the awards. An expected dividend yield of zero is used in the option valuation model, because the Company does not expect to pay any cash dividends in the foreseeable future. At December 31, 2010, the Company does not anticipate any awards will be forfeited in the calculation of compensation expense due to the limited number of employees that receive stock option grants and the Company’s historical employee turnover.

The following table summarizes the stock option activity in the stock based compensation plans:

Loss Per Share

Basic loss per share is based on the weighted-average number of common shares outstanding during each period. Diluted loss per share is based on basic shares as determined above plus the incremental shares that would be issued upon the assumed exercise of in-the-money stock options and warrants using the treasury stock method. The computation of diluted net loss per share does not assume the issuance of common shares that have an anti-dilutive effect on net loss per share. For the years ended December 31, 2010 and 2009, all stock options, warrants and potential shares related to conversion of the Series A, the Series B and the Series C were excluded from the computation of diluted net loss per share. Dilutive shares which could exist pursuant to the exercise of outstanding stock instruments and which were not included in the calculation because their affect would have been anti-dilutive are as follows:


	December 31,
	2010		2009
	(Shares)		(Shares)
Warrants to purchase shares of common stock		51,515,194		50,387,256
Options to purchase shares of common stock		11,794,250		10,260,250
Restricted shares subject to vesting		156,250		2,500,000
Shares of common stock issuable upon conversion preferred stock		15,712,500		10,562,500

Commitments and Contingencies

Lease Commitments

The Company leases its facility under a non-cancelable operating lease that expires in August 2011. In connection with the operating lease, the Company has issued a letter of credit which is secured by restricted cash on deposit with the bank as a security deposit of $59,000. Rent expense under these operating leases was $298,000 and $287,000 for the years ended December 31, 2010 and 2009, respectively.

Future minimum payments under this lease as of December 31, 2010 are as follows (in thousands):

Separation Agreement — Former Chief Executive Officer and Chairman of the Board of Directors

In February 2009, the Company entered into a Separation Agreement in connection with the resignation of David Platt, Ph.D., the Company’s former Chief Executive Officer and Chairman of the Board of Directors.

F-40

The Separation Agreement provides that the Company shall continue to pay Dr. Platt his current salary at a monthly rate of $21,667 for 24 months and that it may defer payment of a portion of such salary amounts greater than $10,000 per month (so long as Dr. Platt does not receive payments of less than the salary payments being made to the Company’s Chief Executive Officer). However, all deferred amounts will continue to accrue and will be payable on the earlier of (i) the Company receiving a minimum of $4.0 million of funding after February 12, 2009, or (ii) February 12, 2011. The Company also agreed to continue to (i) provide health and dental insurance benefits to Dr. Platt, until the first to occur of February 12, 2011 or the date Dr. Platt and his family become eligible to receive health and dental insurance benefits under the plans of a subsequent employer and (ii) make the current monthly lease payments on his automobile until February 12, 2011. The Company recognized the full amount of the salary, health insurance and automobile during the first quarter of 2009. The remaining liability related to this severance is reflected in accrued expenses ($293,000) on the consolidated balance sheet at December 31, 2010 and in accrued expenses ($154,000) and other long-term liabilities ($280,000) on the consolidated balance sheet at December 31, 2009. The final payment was paid to Dr. Platt on February 12, 2011.

The Separation Agreement also provides for the deferral of a $1.0 million severance payment due to Dr. Platt under his employment agreement until the occurrence of any of the following milestone events: (i) the approval by the Food and Drug Administration for a new drug application (“NDA”) for any drug candidate or drug delivery candidate based on the DAVANAT^® technology (whether or not such technology is patented). We also will grant Dr. Platt fully vested cashless stock option with identical terms to purchase at least 500,000 shares of common stock; (ii) consummation of a transaction with a pharmaceutical company expected to result in at least $10.0 million of equity investment or $50 million of royalty revenue to the Company. The Company also will grant Dr. Platt fully vested cashless-exercise stock options exercisable to purchase at least 300,000 shares of common stock for ten (10) years at an exercise price not less than the fair market value of the Common Stock determined as of the date of the grant; or (iii) the renewed listing of our securities on a national securities exchange. Payment upon the events (i) and (iii) may be deferred up to nine months, and if the Company has insufficient cash at the time of any of such events, it may issue Dr. Platt a secured promissory note for such amount. If the Company file a voluntary or involuntary petition for bankruptcy, whether or not a milestone event has occurred, such event shall trigger our obligation to pay the $1.0 million with the result that Dr. Platt may assert a claim for such obligation against the bankruptcy estate. Due to the uncertainties regarding the achievement of any of the milestones as described, the Company has not accrued for the $1.0 million severance nor has it recognized the value of the unissued stock options as of December 31, 2010. When it is deemed probable that one or more of the milestone events will be achieved, the Company will then recognize the $1.0 million severance and the expense related to the issuance of the stock option at that time based on the then current fair value.

Legal Proceedings

Other than claims and legal proceedings that arise from time to time in the ordinary course of business which are not material, the Company has no pending legal proceedings except as follows:

On January 30, 2008, Custom Equity Research, Incorporated (d/b/a Summer Street Research Partners) (“Summer Street”) filed a lawsuit against the Company in the Superior Court of the Commonwealth of Massachusetts, alleging claims for breach of contract, declaratory judgment and unjust enrichment arising out of an engagement letter under which Summer Street agreed to provide institutional investment placement services to the Company. Summer Street claims it is entitled to a placement fee for each placement made during the term of the agreement and for each issuance of securities made or agreed to be made by the Company from October 17, 2007 through November 16, 2008. The Company initially responded to the lawsuit with a motion to dismiss, which the Court denied on June 23, 2008, finding that the letter agreement was ambiguous with respect to Summer Street’s entitlement to compensation. The Court also denied Summer Street’s motion for a prejudgment attachment and trustee process, preliminarily finding that Summer Street was not likely to prevail on any of its claims. The Company filed an answer denying

F-41

Summer Street’s material allegations. Discovery is currently under way. A trial date has been set for November 8, 2011. The Company believes the lawsuit is without merit and intends to contest it vigorously.

The Company is in receipt of a letter dated January 12, 2011 from Maxim Group (“Maxim”), which has acted as a Placement Agent for the Company. The letter advises that Maxim has been named as a respondent in a FINRA arbitration matter commenced by Summer Street, alleging claims for tortious interference with advantageous business and contractual relations, fraud and deceit, negligent misrepresentation, unjust enrichment, violation of Massachusetts Consumer Protection Act, Mass. Gen. Laws ch. 93A, and civil conspiracy, arising out of the Company’s termination of its relationship with Summer Street and its engagement of Maxim as its placement agent. The Company has agreed to indemnify and provide a defense to Maxim in accordance with the Placement Agreements between Maxim and the Company. The Company believes that the arbitration is without merit and intends to assist Maxim in its vigorous defense.

Income Taxes

The components of the net deferred tax assets are as follows at December 31:


	2010			2009
	(in thousands)
Operating loss carryforwards	$	17,242		$	16,572
Tax credit carryforwards		230			212

		17,945			17,060
Less valuation allowance		(17,945	)		(17,060	)

Net deferred tax asset	$	—		$	—

The primary factors affecting the Company’s income tax rates were as follows:


	2010			2009
Tax benefit at U.S. statutory rates		(34.0	%)		(34.0	%)
State tax benefit		(5.3	%)		(5.3	%)
Permanent differences		13.5	%		11.3	%
Research and development credits		(0.9	%)		(0.8	%)
Changes in valuation allowance		26.7	%		28.8	%

		0	%		0	%

As of December 31, 2010, the Company has federal and state net operating loss carryforwards totaling $46,965,000 and $24,109,000 respectively, which expire through 2030. In addition, the Company has federal and state research and development credits of $149,000 and $82,000, respectively, which expire through 2030. Ownership changes, as defined by Section 382 of the Internal Revenue Code, may have

limited the amount of net operating loss carryforwards that can be utilized annually to offset future taxable income. Subsequent ownership changes could further affect the limitation in future years. Because of the Company’s limited operating history and its recorded losses, management has provided, in each of the last two years, a 100% valuation allowance against the Company’s net deferred tax assets.

At December 31, 2010 the Company has $1,082,000 of unrecognized tax benefits, $923,000 of which would affect the effective tax rate. The Company has not recognized an adjustment to the deficit accumulated during the development stage for unrecognized tax benefits because a full valuation allowance has been recorded against net operating loss carry forwards. Since the Company’s net deferred tax assets and the unrecognized tax benefits would not result in a cash payment, the Company has not accrued for any interest and penalties relating to these unrecognized tax benefits. Should the Company incur interest and penalties

F-42

related to income taxes, those amounts would be included in income tax expense. Total amounts of unrecognized tax benefits are not expected to significantly increase or decrease within 12 months of the reporting date.

The Company is subject to taxation in the U.S. and various states. Based on the history of net operating losses all jurisdictions and tax years are open for examination until the operating losses are utilized or the statute of limitations expires.

14.

Subsequent Events

The Company has evaluated all events or transactions that occurred through the date on which the financial statements were issued, noting the following:

Series B Amendments

On January 21, 2011, the Company and 10X Fund amended the Certificate of Designation as follows: (a) to delete the Company’s right to convert the Series B to Common Stock under certain conditions, (b) to extend the Series B-1 and Series B-2 Redemption Date from July 15, 2011 to be the earlier of (i) February 12, 2019 or (ii) the date of issuance of a promissory note to David Platt in connection with the achievement of certain milestones under his separation agreement, (c) to provide that the Company may pay dividends on the Series B on the terms set forth in the original Certificate of Designation beginning with the dividend date due September 30, 2011, and (d) to provide that any shares of Series B that are presented for transfer by 10X (including to its partners) shall be deemed converted into Common Stock on such date.

The Company amended the related Class B Warrants to provide that one-half (warrants for 12,000,000 shares of common stock) may be exercised on a cash-less basis.

The Company amended the related Class A-1 and A-2 Warrants to provide for a 90 day notice rather than 30 days should the Company decide to issue a termination notice with respect to (i) each Class A-1 warrant on any trading day on which the market value of the common stock for each of the 15 previous trading days exceeded $1.25 per share and (ii) each Class A-2 warrant on any trading day on which the market value of the common stock for each of the 15 previous trading days exceeded $1.75 per share.

Warrant and Option Exercises

Subsequent to December 31, 2010, the Company issued 3,757,472 shares of common stock for the exercise of common stock warrants and options, resulting in total net cash proceeds of $2,209,000.

Series C

Subsequent to December 31, 2010, the Company issued an additional 13 shares of Series C, resulting in gross proceeds of $130,000.

Option Grant

On March 9, 2011, the Company announced that its Board of Directors appointed Peter G. Traber, M.D., President and Chief Executive Officer effective March 17, 2011. In conjunction with the appointment of Dr. Traber, the Board of Directors on March 7, 2011 granted Dr. Traber 5,000,000 10-year stock options, at an exercise price of $1.16 per share, which vest as to 750,000 options on the grant date, 625,000 options on the first and second anniversaries of the grant date, 500,000 options on the third and fourth anniversaries of the grant date and 1,000,000 on the Fifth anniversary of the grant date. The remaining 1,000,000 options will vest upon the achievement of certain milestones. With respect to options that vest on anniversaries, exercise rights are accelerated upon achievement of certain milestones.

Item 14.

Indemnification of Directors and Officers.

The registrant’s By-laws, as amended to date, provide for indemnification of officers and directors to the fullest extent permitted by Section 7502 of Chapter 78 of the Nevada Revised Statutes (“NRS”) (as from time to time amended), provided such officer or director acts in good faith and in a manner which such person reasonably believes to be in or not opposed to the best interests of the registrant, and with respect to any criminal matter, had no reasonable cause to believe such person’s conduct was unlawful.

NRS 78.7502 states:

“1. A corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, except an action by or in the right of the corporation, by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with the action, suit or proceeding if he:

(a)

Is not liable pursuant to NRS 78.138; or

(b)

Acted in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful.

The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, does not, of itself, create a presumption that the person is liable pursuant to NRS 78.138 or did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the corporation, or that, with respect to any criminal action or proceeding, he had reasonable cause to believe that his conduct was unlawful.

2. A corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses, including amounts paid in settlement and attorneys’ fees actually and reasonably incurred by him in connection with the defense or settlement of the action or suit if he:

(a)

Is not liable pursuant to NRS 78.138; or

(b)

Acted in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the corporation.

II-1

Indemnification may not be made for any claim, issue or matter as to which such a person has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court in which the action or suit was brought or other court of competent jurisdiction determines upon application that in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper.

3. To the extent that a director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections 1 and 2, or in defense of any claim, issue or matter therein, the corporation shall indemnify him against expenses, including attorneys’ fees, actually and reasonably incurred by him in connection with the defense.”

The registrant’s By-laws also provide that to the fullest extent permitted by NRS 78.751 (as from time to time amended), the registrant shall pay the expenses of officers and directors of the Corporation incurred in defending a civil or criminal action, suit or proceeding, as they are incurred and in advance of the final disposition of such matter, upon receipt of an undertaking in form and substance acceptable to the board of directors for the repayment of such advances if it is ultimately determined by a court of competent jurisdiction that the officer or director is not entitled to be indemnified.

NRS 78.751 states:

“1. Any discretionary indemnification pursuant to NRS 78.7502, unless ordered by a court or advanced pursuant to subsection 2, may be made by the corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances. The determination must be made:

(a)

By the stockholders;

(b)

By the board of directors by majority vote of a quorum consisting of directors who were not parties to the action, suit or proceeding;

(c)

If a majority vote of a quorum consisting of directors who were not parties to the action, suit or proceeding so orders, by independent legal counsel in a written opinion; or

(d)

If a quorum consisting of directors who were not parties to the action, suit or proceeding cannot be obtained, by independent legal counsel in a written opinion.

2. The articles of incorporation, the bylaws or an agreement made by the corporation may provide that the expenses of officers and directors incurred in defending a civil or criminal action, suit or proceeding must be paid by the corporation as they are incurred and in advance of the final disposition of the action, suit or proceeding, upon receipt of an undertaking by or on behalf of the director or officer to repay the amount if it is ultimately determined by a court of competent jurisdiction that he is not entitled to be indemnified by the corporation. The provisions of this subsection do not affect any rights to advancement of expenses to which corporate personnel other than directors or officers may be entitled under any contract or otherwise by law.

3. The indemnification pursuant to NRS 78.7502 and advancement of expenses authorized in or ordered by a court pursuant to this section:

(a)

Does not exclude any other rights to which a person seeking indemnification or advancement of expenses may be entitled under the articles of incorporation or any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, for either an action in his official capacity or an action in another capacity while holding his office, except that indemnification, unless ordered by a court pursuant to NRS 78.7502 or for the advancement of expenses made pursuant to subsection 2, may not be made to or on behalf of any director or officer if a final adjudication establishes that his acts or omissions involved intentional misconduct, fraud or a knowing violation of the law and was material to the cause of action.

II-2

(b)

Continues for a person who has ceased to be a director, officer, employee or agent and inures to the benefit of the heirs, executors and administrators of such a person.”

In addition, the registrant maintains directors’ and officers’ liability insurance which insures against liabilities that its directors and officers may incur in such capacities.

Reference is made to “Undertakings,” below, for the registrant’s undertakings in this registration statement with respect to indemnification of liabilities arising under the Securities Act of 1933, as amended (the “Securities Act”).

Item 17.

Undertakings.

Insofar as indemnification by the registrant for liabilities arising under the Securities Act, may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions referenced in Item 14 of this registration statement, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. If a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by a director, officer or controlling person in connection with the securities being registered hereunder, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act, and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes that:

1. To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered

II-4

would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

2. That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and this offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

3. To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of this offering;

4.

Ladies and Gentlemen:

We have acted as counsel to Pro-Pharmaceuticals, Inc., a Nevada corporation (the “Company”) in connection with its Post-Effective Amendment No. 4 on Form S-1 to Registration Statement on Form S-3 (the “Registration Statement”) filed the by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933 (the “Securities Act”) which contains a combined prospectus registering the sale or resale of an aggregate of 9,147,500 shares of the Company’s common stock, par value $0.001 par value (the “Shares”). The Shares are issuable upon conversion of shares of the Company’s Series A 12% Convertible Preferred Stock (“the “Series A Preferred”) or exercise of warrants issued in connection with the Series A Preferred or sold by the Company in February 2008 (collectively, the “Warrants”).

On the basis of such investigation as we have deemed necessary, we are of the opinion that (i) the Shares have been duly authorized for issuance, and (ii) when issued upon conversion pursuant to the terms of the Series A Preferred or upon payment pursuant to exercise of the Warrants in accordance with their terms, the Shares will be fully paid and non-assessable shares of the common stock of the Company.

We hereby consent to the filing of this opinion as an exhibit to, and all references to our firm contained in, the Registration Statement. In giving this consent, we do not thereby admit that we come within the category of persons whose consent is required under Section 7 of the Securities Act or the General Rules and Regulations of the Commission.

Very truly yours
