PRO-PHARMACEUTICALS, INC. (A Development Stage Company) NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) March 31, 2002 - -------------------------------------------------------------------------------- 1. NATURE OF OPERATIONS, BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES NATURE OF OPERATIONS Pro-Pharmaceuticals, Inc. (the Company) was established in July 2000. The Company is in the development stage and is engaged in developing technology that will reduce toxicity and improve the efficacy of currently existing chemotherapy drugs by combining the drugs with a number of specific carbohydrate compounds. The carbohydrate-based drug delivery system may also have applications for drugs now used 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. Its product candidates are still in the research and development stage, with none yet in clinical trials. 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, lack of experience in clinical trials, need for regulatory approval of products, risks associated with protection of intellectual property, and competition with larger, better-capitalized companies. To date, the Company has raised capital principally through the issuance of convertible notes and the sale of common stock through a private placement. The Company's financial statements have been presented on a going-concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The Company is in the development stage, has incurred a net loss since inception of $5,107,148 and expects to incur additional losses in the near future. These factors raise substantial doubt about the Company's ability to continue as going concern. Successful completion of the Company's development program and, ultimately, the attainment of profitable operations is dependent upon future events, including maintaining adequate financing to fulfill its development activities and achieving a level of sales adequate to support the Company's cost structure. The Company is actively seeking additional financing to fund future operations and future significant investments in the business. However, there can be no assurance that the Company will be able to obtain financing on acceptable terms, or at all. 4

BASIS OF PRESENTATION The condensed financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. These condensed financial statements should be read in conjunction with the financial statements and the notes thereto included in the Company's latest annual report on Form 10-KSB. The condensed financial statements, in the opinion of management, include all adjustments (consisting of normal recurring adjustments) necessary to present fairly the Company's financial position and the results of operations. These results are not necessarily indicative of the results to be expected for the entire year. SIGNIFICANT ACCOUNTING POLICIES The significant accounting policies followed by the Company in preparing its financial statements are set forth in Note 1 to the financial statements included in its Form 10-KSB for the year ended December 31, 2001. The Company has made no changes to these policies during this quarter. 2. NET LOSS PER SHARE Basic and diluted net loss per share is presented in conformity with Statement of Financial Accounting Standards (SFAS) No. 128, Earnings per Share, for all periods presented. In accordance with SFAS No. 128, basic and diluted net loss per common share was determined by dividing net loss applicable to common stockholders by the weighted average common shares outstanding during the period, less shares subject to repurchase. Diluted weighted-average shares are the same as basic weighted-average shares since the inclusion of 2,078,091 shares issuable pursuant to the exercise of stock options and warrants and conversion of convertible debt as of March 31, 2002 and December 31, 2001 would have been antidilutive. 5

3. PROPERTY AND EQUIPMENT Property and equipment consists of the following at March 31, 2002 and December 31, 2001: March 31, December 31, 2002 2001 Property and equipment: Computer and office equipment $ 62,583 $ 56,681 Furniture and fixtures 39,746 39,746 Leasehold improvements 52,669 27,269 --------- --------- Total 154,998 123,696 Less accumulated depreciation (20,627) (12,156) --------- --------- Property and equipment - net $ 134,371 $ 111,540 4. CONVERTIBLE NOTES PAYABLE AND CURRENT EQUITY OFFERING Subsequent to March 31, 2002, the $195,000 of convertible notes were extended by the Company for an additional one year period. As consideration for agreeing to the extension the Company is required to issue 48,750 shares of common stock to the holders of these notes. The value of these shares will be recorded as interest expense when issued. On December 13, 2001, the Company commenced a public offering of 1,428,572 shares of common stock, at a price to the public of $3.50 per share, pursuant to a registration statement on Form SB-2 as originally filed and declared effective by the SEC on December 12, 2001, and subsequently amended by Post-Effective Amendment No. 1 declared effective by the SEC on April 29, 2002. The Company anticipated concluding the offering on February 11, 2002 but extended the offering until June 11, 2002. As of April 8, 2002, the Company had received proceeds for, but not issued, approximately 50,570 shares pursuant to this public offering. As part of this offering, the Company has received advance deposits of $156,000 for common stock. These deposits are for shares anticipated to be issued subsequent to satisfaction of state security law requirements. Such deposits have been classified as current liabilities since there is the possibility, should such state requirements not be met, amounts would be returned to investors. 5. OPTIONS AND WARRANTS Under an agreement with a shareholder for consulting services the Company will compensate the shareholder for services rendered with options for the purchase of 2,000 shares per month beginning on March 1, 2002. Under this agreement 2,000 options were granted during the three month period ended March 31, 2002. These options were valued by the Company at $4,291 which was recognized as a 6

general and administrative expense in the statement of operations for the period ended March 31, 2002. The Company had previously incurred a liability of approximately $50,000 to finders in connection with its 2001 debt offering. In the first quarter of 2002, in response to certain liquidity issues, the Company settled this liability in the form of 110,000 warrants. The warrants are exercisable immediately, have an exercise price of $3.50 per share and a 10 year life. These warrants were valued by the Company at $235,987 which was recorded as interest expense in the statement of operations for the period ended March 31, 2002. 6. RECENT ACCOUNTING PRONOUNCEMENTS On January 1, 2002, the Company adopted Statement of Financial Accounting Standards (SFAS) No.144, Accounting for the Impairment or Disposal of Long-Lived Assets, which addresses financial reporting for the impairment or disposal of long-lived assets. SFAS 144 supersedes SFAS 121 and the accounting and reporting provisions of APB 30 related to the disposal of a segment of a business. The adoption of this statement did not have a significant effect on the Company's financial position or results of operations. 7. CONTINGENCY GlycoGenesys, Inc. (formerly known as SafeScience, Inc.), former employer of Dr. David Platt, Chairman and Chief Executive Officer of the Company, alleged in a letter dated February 15, 2001 that Dr. Platt's activity with the Company is a violation of a noncompetition covenant he has with GlycoGenesys, Inc. Dr. Platt responded by letter dated February 19, 2001 denying the allegations and inviting a meeting to discuss them. Counsel for GlycoGenesys, Inc. indicated a willingness to resolve these matters but attempts to set up a meeting were unsuccessful. An evaluation cannot be made at this time of the likelihood of a favorable or unfavorable outcome, nor can any estimate be made as to the amount or range, if any, of potential loss. If GlycoGenesys, Inc. makes demands against the Company with respect to the allegations, the Company intends to vigorously contest all such allegations. 7

Item 2. Plan of Operation This quarterly report on Form 10-QSB contains, in addition to historical information, forward-looking statements. 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 such 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, the following: uncertainties as to the utility and market for our potential products; uncertainties associated with preclinical and clinical trials of our drug delivery candidates; our lack of experience in product development and expected dependence on potential licensees and collaborators for commercial manufacturing, sales, distribution and marketing of our potential products; possible development by competitors of competing products and technologies; lack of assurance regarding patent and other protection of our proprietary technology; compliance with and change of government regulation of our activities, facilities and personnel; uncertainties as to the extent of reimbursement for our potential products by government and private health insurers; our dependence on key personnel; our history of operating losses and accumulated deficit; and economic conditions related to the biotechnology and biopharmaceutical industry, each as discussed in our Annual Report on Form 10-KSB for the year ended December 31, 2001, filed with the Securities and Exchange Commission. 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 have no obligation to publicly update forward-looking statements we make in this Form 10-QSB. Overview We are currently in the development stage and have not yet generated any operating revenues. Since the formation in July 2000 of our predecessor, Pro-Pharmaceuticals, Inc., a Massachusetts corporation, we have been engaged in research and development activities in connection with identifying and developing a technology that will reduce toxicity and improve the efficacy of currently-used drug therapies, including cancer chemotherapies, by combining the drugs with a number of carbohydrate compounds. Our preliminary studies have identified certain mannans, a group of polysaccharides, that could be utilized as a potential drug delivery system. Polysaccharides are molecules consisting of one or more types of sugars. In the case of mannans, the principal component is the sugar mannose, which is similar to glucose. We believe that a mannan having a suitable chemical structure and composition, when attached to or combined with the active agent of a chemotherapy drug, would increase cellular membrane fluidity and permeability, thereby assisting delivery of the drug. Preclinical Animal Studies; Investigational New Drug Application As discussed below, we have conducted preclinical animal experiments to study the toxicity and efficacy of 5-Fluorouracil (5-FU) in combination with our mannan compounds. We are also conducting similar preclinical animal experiments to study Adriamycin both in combination with our mannan compounds and as chemically modified with sugar residues via "linkers" of a certain chemical structure that are our proprietary technology. We named the most promising of our synthesized Adriamycin sugar derivatives "Galactomycin" (further discussed below). All of our animal experiments are conducted at independent laboratories. We intend to include the preclinical data obtained from the 5-FU studies in an Investigational New Drug application (IND) to be submitted to the FDA. We conducted a pre-IND meeting with the FDA on May 3, 2002 and were authorized to submit the IND, which we intend to do shortly. 8

Toxicity Studies Results of one toxicity study conducted in early 2001 indicate that one of our mannan compounds, named Davanat-1, may significantly decrease the toxicity of 5-FU. Ten groups of five animals each were used. In five groups, treated respectively with a placebo and one of four different mannans provided by us, the animals showed no signs of toxicity. That was expected because the animals were not receiving the toxic drug, and the mannans were not expected to be toxic at all. In four groups, treated respectively with 5-FU alone and 5-FU in combination with either of three of the mannans, the animals showed signs of severe toxicity. In one group, treated with 5-FU in combination with the fourth mannan, Davanat-1, no clinical signs of toxicity were observed. This provides a preliminary indication of potential reduction in cancer drug toxicity by a carbohydrate-based addition to the cancer drug. A second, similar study, also conducted in early 2001, was performed to test a potential reduction of toxicity of another anticancer drug, Adriamycin, in combination with each of two mannan compounds selected for the study. Results indicate that one of the mannan compounds may decrease the toxicity of Adriamycin. In two groups, treated with Adriamycin alone and Adriamycin in combination with one mannan, the animals showed signs of severe toxicity. In one group, treated with the same amount of Adriamycin in combination with the second mannan, four out of the five animals in the group did not show any clinical signs of toxicity. Again, this provides a preliminary indication of potential reduction in cancer drug toxicity by a carbohydrate-based addition to the cancer drug. The fact that two different cancer drugs with chemically unrelated structures showed a marked reduction of their toxicity in combination with particular mannans indicates that there might be some fundamental underlying biological reasons, related to the mannans rather than to the drugs, for the reduction in toxicity. In four subsequent preclinical experiments conducted in June and September 2001, we studied on larger animals the toxicity reduction of 5-FU in combination with Davanat-1, which had demonstrated toxicity reduction in the prior 5-FU study. These experiments were performed in accordance with FDA guidelines and recommendations on rats (acute and long-term toxicity study) and dogs (acute and long-term toxicity study) measuring the effect of the 5-FU/Davanat-1 combination on blood structure and survival of these animals. Preliminary results indicate that the 5-FU/Davanat-1 combination decreased toxicity using this measure because it resulted in lower animal mortality and decreased loss of blood structure components in comparison to the results of tests which administered 5-FU alone. We are presently conducting additional toxicity studies on larger animals using particularly high Davanat-1 doses. Efficacy Study A preliminary study was performed to test a potential change in therapeutic efficacy of 5-FU in a combination with Davanat-1, which had decreased toxicity of the drug in healthy animals (see the first study described in " -- Toxicity Studies," above). The study was motivated by the desire to test the possibility that Davanat-1 might diminish both toxicity and efficacy in parallel, if the Davanat-1 were merely competing with 5-FU for binding with cells, healthy or cancerous. Results of the study demonstrated, however, that Davanat-1, which may decrease toxicity of 5-FU, may also increase efficacy of the drug when the drug combined with Davanat-1 is administered into cancer-carrying animals. In this study, we ascertained a decrease in tumor size following administration of 5-FU alone as well as administration of the 5-FU/Davanat-1 combination. When the 5-FU/Davanat-1 combination was administered, the time for the tumor to quadruple in size in the animals increased from 24 days (5-FU alone administered) to 56 days (5-FU/Davanat-1 combination administered) relative to 12 days for control animals (no drug administered). 9

At the request of the FDA for a better understanding of the Davanat-1 mode of therapeutic action, we are currently conducting two additional efficacy studies using 5-FU and Davanat-1 in combination with leucovorin, another cancer chemotherapy. We also conducted a study that involved injecting radiolabeled Davanat-1 (with and without 5-FU) into tumor-free and tumor-bearing animals. The study provided extensive experimental data with respect to Davanat-1 distribution in organs and tissues (liver, kidney, lungs, plasma, and tumor) and the capacity of such organs and tissue to clear Davanat-1 after various time periods. The study indicated that Davanat-1 may protect the liver from a toxic effect of 5-FU yet increase the amount, and hence the therapeutic effect, of 5-FU in the tumor. In other words, we have indications that Davanat-1 may decrease toxicity and increase efficacy of 5-FU. Carbohydrate-Cancer Drug Formulations We are currently developing formulations of carbohydrates linked to anti-cancer drugs. We have chemically synthesized four novel products that are carbohydrate derivatives of Adriamycin, and have conducted preclinical animal experiments, studying both toxicity (on healthy animals) and efficacy (on cancer-carrying animals). Preliminary results of these experiments indicate that all four of the synthesized carbohydrate-Adriamycin compounds, and particularly one, named Galactomycin, are significantly less toxic compared with the original Adriamycin, and demonstrate therapeutic efficacy as well. In the case of Galactomycin, the preliminary results indicated a therapeutic efficacy higher than that for the parent Adriamycin, particularly at repeated administrations. Unlike repeated injections of Adriamycin which result in a cumulative toxic effect, Galactomycin at repeated injections apparently increases its therapeutic effect while retaining low toxicity. Although the foregoing studies are encouraging, the results achieved in preclinical studies with animals are often not duplicated in human patients. Please see "Risk Factors That May Affect Results -- Our product candidates will be based on novel technologies" in our 2001 Form 10-KSB. We have no products and have not yet conducted any clinical trials. We have initiated large-scale production of our mannan for use in forthcoming clinical trials. Intellectual Property Protection We have six pending utility patent applications in the United States. The patent applications cover methods and compositions for reducing side effects in chemotherapeutic formulations, and improving efficacy and reducing toxicity of chemotherapeutic agents. Two of our utility patents are filed worldwide under the Patent Cooperation Treaty. We filed with the U.S. Patent and Trademark Office (PTO) applications to register the following trademarks/service marks: ADVANCING DRUGS THROUGH GLYCOSCIENCE; GLYCO-UPGRADE; PRO-PHARMACEUTICALS, INC.; DAVANAT; UCLT and UNIVERSAL CARBOHYDRATE LINKER TECHNOLOGY. In February 2002, the PTO issued Notices of Allowance for two of these marks, ADVANCING DRUGS THROUGH GLYCOSCIENCE, and GLYCO-UPGRADE. In order to obtain registrations, we must file evidence of use by August 2002, or we must file an for an extension of time to provide evidence of use. In January 2002, the PTO informed us that the mark PRO-PHARMACEUTICALS, INC. has been approved for publication. Unless an opposition to registration is timely filed, the PTO will issue a Notice of Allowance for this mark. 10

Plan of Operation As discussed in our 2001 Form 10-KSB, we were incorporated in January 2001 for the purpose of effecting a business combination with Pro-Pharmaceuticals, Inc., a Massachusetts corporation engaged in a business we desired to acquire. The transaction included a merger in which we are the surviving corporation. Our capital resources to date consist of (i) the proceeds of a private placement of convertible notes issued and sold by the predecessor Massachusetts company in anticipation of its being acquired by us; (ii) the proceeds of a private placement begun in May 2001 of our common stock and stock purchase warrants; and (iii) the proceeds of our public offering of common stock begun in December 2001. Each is further described below. For further detail as to these offerings, please refer to our 2001 Form 10-KSB. In the private placement of convertible notes, which commenced in December 2000 and continued through May 2001, our predecessor Pro-Pharmaceuticals (Massachusetts) issued convertible notes with an aggregate principal amount of $1,320,602 to "accredited investors" as such term is defined in Regulation D promulgated under the Securities Act of 1933. These notes became our corporate obligations as a result of the merger with Pro-Pharmaceuticals (Massachusetts). In connection with this convertible note, we issued 660,321 shares of common stock. Each holder was entitled to receive one-half share of our common stock for each whole dollar amount of principal. These shares were formally issued in July 2001. In August 2001, we offered warrants to holders of our outstanding convertible notes as an inducement to convert. Holders representing $1,125,602 of the outstanding principal and accrued interest chose to convert at a conversion price of $2.00 per share and received 598,229 common shares and 598,229 warrants. The warrants have an exercise price of $6.50 per share, are immediately exercisable and expire on October 1, 2005 subject to our right to accelerate exercise of the warrant under certain circumstances as described in our 2001 Form 10-KSB. As of March 31, 2002, all but $195,000 aggregate principal amount of these notes had been converted to shares of our common stock. In April 2002, we extended the maturity date for the $195,000 of outstanding notes for one year. In consideration for the extension, 48,750 shares of common stock will be issued to the holders of the outstanding notes. In May 2001, we began a private placement of securities exempt from registration pursuant to Rule 506 of Regulation D under the Securities Act of 1933 in order to raise $5,145,000 to cover our expenditures. We terminated this private placement as of December 3, 2001. As of the termination of this offering in December 2001, we had received proceeds of $2,237,500 from the sale of the securities offered in this private placement. Such purchases resulted in our issuing 689,300 shares of our common stock and warrants to purchase 889,300 shares of our common stock. On December 13, 2001, we commenced a public offering of 1,428,572 shares of our common stock, at a price to the public of $3.50 per share, pursuant to a registration statement on Form SB-2 as originally filed and declared effective by the SEC on December 12, 2001, and subsequently amended by Post-Effective Amendment No. 1 declared effective by the SEC on April 29, 2002. We anticipated concluding the offering on February 11, 2002 but extended the offering until June 11, 2002. As of April 8, 2002, we had received proceeds for, but not issued, approximately 50,570 shares pursuant to our public offering. As of March 31, 2002, we had approximately $967,000 in cash and cash equivalents. We have budgeted expenditures for the twelve-month period ending March 31, 2003, of $5,500,000, comprised of anticipated expenditures for research and development ($4,200,000), general and administrative ($1,100,000), equipment and leaseholds ($100,000) and contingency allowance ($100,000). 11

For the year ended December 31, 2001, our financial statements have been presented on a going-concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. Pro-Pharmaceuticals is in the development stage, has incurred a net loss since inception of approximately $5,107,000 and expects to incur additional losses in the near future. Successful completion of our development program and, ultimately, the attainment of profitable operations is dependent upon future events, including maintaining adequate financing to fulfill our development activities and achieving a level of sales adequate to support our cost structure. We are actively seeking additional financing to fund future operations and future significant investments in the business. However, there can be no assurance that we will be able to obtain financing on acceptable terms, or at all. Additional funds may be raised through additional equity financings, as well as borrowings and other resources. With the capital we have raised to date, and the additional $5,000,000 that we are attempting to raise under our public offering of common stock that commenced in December 2001, we believe that we will be able to proceed with our current plan of operations and meet our obligations for approximately the next twelve months. If we do not raise the additional funds, we will have to cut our research and development expenditures, which would substantially slow progress that we might expect to make during the next twelve months in development of our business including commencement of clinical trials. During the next twelve months, we anticipate that our research and development activities will include commencement of a Phase I first-in-man clinical trial to determine the safety of our Davanat-1 carbohydrate, as well as continuing preclinical animal experiments to study toxicity and efficacy of 5-FU and other cancer chemotherapies both in combination with our mannan compounds and, in the case of Adriamycin, as chemically modified with sugar residues via "linkers" of a certain chemical structure that are our proprietary technology. As we have done to date, we will have our pre-clinical testing done by outside laboratories. We do not anticipate building in-house research or development facilities, or hiring staff to conduct those activities. Consequently, we do not expect to make any purchases or sales of plant or significant equipment during the next twelve months, and we expect to maintain an employee headcount of three to four. We currently have three employees, all full-time. We expect to generate losses from operations for several years due to substantial additional research and development costs, including costs related to clinical trials. Our future capital requirements will depend on many factors, in particular our progress in and scope of our research and development activities, and the extent to which we are able to enter into collaborative efforts for research and development and, later, manufacturing and marketing products. We may need additional capital to the extent we acquire or invest in businesses, products and technologies. If we should require additional financing due to unanticipated developments, additional financing may not be available when needed or, if available, we may not be able to obtain this financing on terms favorable to us or to our stockholders. Insufficient funds may require us to delay, scale back or eliminate some or all of our research and development programs, or may adversely affect our ability to operate as a going concern. If additional funds are raised by issuing equity securities, substantial dilution to existing stockholders may result. 12
