 Galectin Therapeutics Inc. (the &amp;#x201C;Company&amp;#x201D;) is a
 development-stage company that is applying its leadership in
 galectin science and drug development to create new therapies for
 fibrotic disease and cancer. These therapeutic candidates are based
 on the Company&amp;#x2019;s targeting of galectin proteins which are key
 mediators of biologic and pathologic functions. These compounds
 also may have application for drugs to treat other diseases and
 chronic health conditions.&lt;/p&gt;

 The unaudited condensed consolidated financial statements as
 reported in this Quarterly Report on Form 10-Q reflect all
 adjustments which are, in the opinion of management, necessary to
 present fairly the financial position of the Company as of
 September&amp;#xA0;30, 2013 and the results of its operations for the
 three and nine months ended September&amp;#xA0;30, 2013 and 2012 and
 the cumulative period from inception (July 10, 2000) through
 September&amp;#xA0;30, 2013 and its cash flows for the nine months
 ended September&amp;#xA0;30, 2013 and 2012, and for the cumulative
 period from inception (July 10, 2000) to September&amp;#xA0;30, 2013.
 Such adjustments, other than nonrecurring adjustments that have
 been separately disclosed, are of a normal, recurring nature. The
 Company considers events or transactions that occur after the
 balance sheet date but before the financial statements are issued
 to provide additional evidence relative to certain estimates or to
 identify matters that require additional disclosure. Subsequent
 events have been evaluated through the date these financial
 statements are available to be issued. The results for interim
 periods are not necessarily indicative of results which may be
 expected for any other interim period or for the full year. The
 unaudited condensed consolidated financial statements of the
 Company should be read in conjunction with its Annual Report on
 Form 10-K for the year ended December&amp;#xA0;31, 2012.&lt;/p&gt;
 &lt;p style="TEXT-TRANSFORM: none; MARGIN-TOP: 12pt; TEXT-INDENT: 13%; LETTER-SPACING: normal; FONT: 10pt &apos;Times New Roman&apos;; WHITE-SPACE: normal; MARGIN-BOTTOM: 0pt; COLOR: rgb(0,0,0); WORD-SPACING: 0px; -webkit-text-stroke-width: 0px"&gt;
 The Company has operated at a loss since its inception and has had
 no significant revenues. The Company anticipates that losses will
 continue for the foreseeable future as is develops its therapeutic
 candidates. At September&amp;#xA0;30, 2013, the Company had $9,715,000
 of unrestricted cash and cash equivalents available to fund future
 operations. Subsequent to September&amp;#xA0;30, 2013, the Company
 received $1,580,600 from the exercise of warrants and stock options
 for 556,667 shares of common stock. Additionally subsequent to
 September 30, 2013, the Company had issued 50,643 shares of its
 common stock through its At Market issuance program (see Note 9) at
 an average price of $10.82 per share resulting in net proceeds of
 approximately $531,000. The Company believes that with the cash on
 hand at September&amp;#xA0;30, 2013 and the cash received subsequent to
 quarter end, there is sufficient cash to fund operations into the
 third quarter of 2014. The Company&amp;#x2019;s ability to fund
 operations after its current cash resources are exhausted depends
 on its ability to obtain additional financing or achieve profitable
 operations, as to which no assurances can be given. The Company has
 developed plans, including cost containment efforts in the event
 that such financing cannot be realized by the Company. Accordingly,
 based on the forecasts and estimates underlying the Company&amp;#x2019;s
 current operating plan, the financial statements do not currently
 include any adjustments that might be necessary if the Company is
 unable to continue as a going concern.&lt;/p&gt;
 &lt;p style="TEXT-TRANSFORM: none; MARGIN-TOP: 12pt; TEXT-INDENT: 13%; LETTER-SPACING: normal; FONT: 10pt &apos;Times New Roman&apos;; WHITE-SPACE: normal; MARGIN-BOTTOM: 0pt; COLOR: rgb(0,0,0); WORD-SPACING: 0px; -webkit-text-stroke-width: 0px"&gt;
 As shown in the condensed consolidated financial statements, the
 Company incurred cumulative net losses applicable to common
 stockholders of $99.1 million for the cumulative period from
 inception (July 10, 2000) through September&amp;#xA0;30, 2013. The
 Company&amp;#x2019;s net losses have resulted principally from costs
 associated with (i)&amp;#xA0;research and development expenses,
 including clinical trial costs, (ii)&amp;#xA0;general and
 administrative activities and (iii)&amp;#xA0;the Company&amp;#x2019;s
 financing transactions including interest, dividend payments, and
 the costs related to fair value accounting for the Company&amp;#x2019;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 September&amp;#xA0;30, 2013, the Company had raised a net total
 of $74.9 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 September&amp;#xA0;30, 2013, the Company used
 cash of $64.4 million in its operations.&lt;/p&gt;
 &lt;p style="TEXT-TRANSFORM: none; MARGIN-TOP: 12pt; TEXT-INDENT: 13%; LETTER-SPACING: normal; FONT: 10pt &apos;Times New Roman&apos;; WHITE-SPACE: normal; MARGIN-BOTTOM: 0pt; COLOR: rgb(0,0,0); WORD-SPACING: 0px; -webkit-text-stroke-width: 0px"&gt;
 The Company was founded in July 2000, was incorporated in the State
 of Nevada in January 2001 under the name
 &amp;#x201C;Pro-Pharmaceuticals, Inc.,&amp;#x201D; and changed its name to
 &amp;#x201C;Galectin Therapeutics Inc.&amp;#x201D; on May&amp;#xA0;26,
 2011.&amp;#xA0;On&amp;#xA0;March&amp;#xA0;23, 2012, the Company began trading
 on The NASDAQ Capital Market under the symbol GALT. Immediately
 prior to March&amp;#xA0;23, 2012, the Company was traded on the
 Over-the Counter Bulletin Board (&amp;#x201C;OTCBB&amp;#x201D;) under the
 symbol GALT.OB.&lt;/p&gt;
 &lt;p style="TEXT-TRANSFORM: none; MARGIN-TOP: 12pt; TEXT-INDENT: 13%; LETTER-SPACING: normal; FONT: 10pt &apos;Times New Roman&apos;; WHITE-SPACE: normal; MARGIN-BOTTOM: 0pt; COLOR: rgb(0,0,0); WORD-SPACING: 0px; -webkit-text-stroke-width: 0px"&gt;
 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&amp;#x2019;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&amp;#x2019;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.&lt;/p&gt;

 The Company has certain financial assets and liabilities recorded
 at fair value. Fair values determined by Level 1 inputs utilize
 observable data such as quoted prices in active markets. Fair
 values determined by Level 2 inputs utilize data points other than
 quoted prices in active markets that are observable either directly
 or indirectly. Fair values determined by Level 3 inputs utilize
 unobservable data points in which there is little or no market
 data, which require the reporting entity to develop its own
 assumptions. The carrying amounts reflected in the consolidated
 balance sheets for cash equivalents, accounts payable and accrued
 expenses approximates their carrying value due to their short-term
 nature. Included in cash and cash equivalents, as of
 September&amp;#xA0;30, 2013 and December&amp;#xA0;31, 2012, the Company had
 $0 and $583,000, respectively invested in money market funds which
 had calculated net asset values and were therefore classified as
 Level 2. There were no level 3 assets held at fair value at
 September&amp;#xA0;30, 2013 or December&amp;#xA0;31, 2012.&lt;/p&gt;

 &lt;p style="MARGIN-TOP: 6pt; TEXT-INDENT: 4%; FONT-FAMILY: Times New Roman; MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt"&gt;
 On May&amp;#xA0;6, 2013, the Company modified the terms of the
 Class&amp;#xA0;A-2 and Class B warrants that were originally issued to
 the 10X Fund with the Series B Preferred Stock offering. The Class
 B warrants were modified to allow for the cashless exercise of all
 4,000,000 outstanding Class B warrants. Previously, only half of
 the Class B warrants allowed for cashless exercise. The
 Class&amp;#xA0;A-2 warrants for the purchase of 1,000,000 shares of
 common and all of the Class B warrants had their exercisable life
 extended by an additional five years. In exchange for these
 modifications, the 10X Fund agreed to a future amendment of the
 Company&amp;#x2019;s Series B certificate of designation to remove the
 redemption provision such that the Series B Preferred Stock will no
 longer be redeemable, if and when the Company will no longer be
 required to issue Dr.&amp;#xA0;Platt a promissory note as may currently
 be required under the separation agreement (see Note
 8).&amp;#xA0;Should the Company amend their Series B certificate of
 designation in the future as described above, the Company will be
 required at that time to evaluate whether such amendment is to be
 accounted for as a modification or an extinguishment of the
 Company&amp;#x2019;s Series B Preferred Stock.&amp;#xA0;The Company has
 accounted for the modified terms of the Class&amp;#xA0;A-2 and Class B
 warrants pursuant to ASC 718, Stock Compensation, whereby the
 Company has recognized a charge for the change in fair value of the
 warrants immediately before and immediately after the
 modification.&amp;#xA0;For the three and six month period ended
 June&amp;#xA0;30, 2013, the Company recognized a charge of $8,763,000
 related to the extension of the 5,000,000 warrants. The following
 assumptions were used to value the extension of the warrants
 immediately before and immediately after the modification: a)
 immediately before the modification&amp;#x2014;an expected life range of
 0.77 to 2.01 years, volatility range of 77% to 96%, risk free
 interest rate range of 0.11% to 0.22% and zero dividends and; b)
 immediately following the modification&amp;#x2014;an expected life range
 of 5.78 to 7.02 years, volatility range of 113% to 122%, risk free
 interest rate range of 0.74% to 1.19% and zero dividends.&lt;/p&gt;
 &lt;p style="MARGIN-TOP: 18pt; FONT-FAMILY: Times New Roman; MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt"&gt;

 &lt;p style="MARGIN-TOP: 6pt; TEXT-INDENT: 13%; FONT-FAMILY: Times New Roman; MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt"&gt;
 In January 2013, the Company entered into an agreement with a
 consultant that provided for the grant of warrants for the purchase
 of 5,000 shares of common stock at an exercise price of $2.65 per
 share. The following assumptions were used to value the warrants:
 an expected life of 3 years, volatility of 87%, risk free interest
 rate of 0.42% and zero dividends. The Company recognized an expense
 of $7,000 related to these warrants at the time of the grant as
 they were vested at issuance. The warrants were exercised in
 September 2013.&lt;/p&gt;

 Basic net loss per common share is computed by dividing the net
 loss available to common stockholders by the weighted average
 number of common shares outstanding during the period. Diluted net
 loss per common share is computed by dividing the net loss
 available to common stockholders by the weighted average number of
 common shares and other potential common shares then outstanding.
 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. 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:&lt;/p&gt;

 On October&amp;#xA0;25, 2013, the Company entered into an At Market
 Issuance Sales Agreement (the &amp;#x201C;At Market Agreement&amp;#x201D;)
 with a sales agent under which the Company may issue and sell
 shares of its common stock having an aggregate offering price of up
 to $30.0 million from time to time through the sales agent. Sales
 of the Company&amp;#x2019;s common stock through the sales agent, if
 any, will be made by any method that is deemed an &amp;#x201C;at the
 market&amp;#x201D; offering as defined by the U.S. Securities and
 Exchange Commission. The Company will pay to the sales agent a
 commission rate equal to 3.0% of the gross proceeds from the sale
 of any shares of common stock sold through the sales agent under
 the At Market Agreement. Subsequent to September 30, 2013, the
 Company had issued 50,643 shares of its common stock through its At
 Market issuance program at an average price of $10.82 per share
 resulting in net proceeds of approximately $531,000.&lt;/p&gt;

 As of September&amp;#xA0;30, 2013, there was $5,086,000 of unrecognized
 compensation related to 1,515,137 unvested options, which is
 expected to be recognized over a weighted&amp;#x2013;average period of
 approximately 4.2 years. The weighted-average grant date fair value
 for options granted during the three and nine months ended
 September&amp;#xA0;30, 2013 was $3.55 and $3.17, respectively. The
 weighted-average grant date fair value for options granted during
 the three and nine months ended September&amp;#xA0;30, 2012 was $1.89
 and $1.72, respectively.&lt;/p&gt;
 &lt;p style="MARGIN-TOP: 12pt; TEXT-INDENT: 13%; FONT-FAMILY: Times New Roman; MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt"&gt;
 The fair value of all other options granted is determined using the
 Black-Scholes option-pricing model. The following weighted average
 assumptions were used:&lt;/p&gt;

 On September&amp;#xA0;26, 2013, the Company modified certain vested
 stock options held by a former member of the Company&amp;#x2019;s board
 of directors. The individual left the board on May&amp;#xA0;23, 2013.
 The modification extended the contractual period of exercise of
 103,158 stock options until the end of their original terms instead
 of such options expiring 3 months after service on the board ended.
 As a result, the Company recorded a non-cash charge of $930,000
 related to the modification in the quarter ended September&amp;#xA0;30,
 2013.&lt;/p&gt;

 &lt;i&gt;Agreement with CTI for Phase I Clinical Trial&lt;/i&gt;&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 On&amp;#xA0;February 1, 2013, the Company entered into an Amended and
 Restated Master Services Agreement (the &amp;#x201C;Agreement&amp;#x201D;)
 with CTI Clinical Trial Services, Inc. and CTI Clinical Consulting
 Services, Inc.&amp;#xA0;(individually and collectively,
 &amp;#x201C;CTI&amp;#x201D;), whereby CTI is assisting the Company in the
 design, development and conduct of one or more clinical research
 studies from time to time.&amp;#xA0;All work performed by CTI for the
 Company is being conducted pursuant to the terms of work orders
 that describe the specific obligations undertaken by CTI with
 respect to any particular clinical research study sponsored or
 conducted by the Company.&amp;#xA0;Unless otherwise terminated sooner
 in accordance with the terms of the Agreement, the Agreement will
 be effective until January&amp;#xA0;31, 2018.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 On February&amp;#xA0;1, 2013, the Company entered into a work order
 (the &amp;#x201C;Work Order&amp;#x201D;) with CTI in accordance with the
 terms of the Agreement.&amp;#xA0;The Work Order provides that CTI will
 provide services with respect to the Company&amp;#x2019;s Phase I
 Clinical Trial to evaluate the safety of the Company&amp;#x2019;s drug
 GR-MD-02 in subjects with Non-Alcoholic Steatohepatitis
 (&amp;#x201C;NASH&amp;#x201D;) with advanced hepatic fibrosis.&amp;#xA0;CTI is
 providing the following services, amongst others,&amp;#xA0;with respect
 to the Work Order: reviewing and providing notices regarding IND
 safety reports, selecting investigators and monitors for the study,
 informing investigators of new observations, monitoring the
 progress of the study and reviewing ongoing investigations, keeping
 certain records, inspecting the Company&amp;#x2019;s records and
 reports, and disposing of any unused supply of the investigational
 drug.&lt;/p&gt;
 &lt;p style="font-size:1px;margin-top:12px;margin-bottom:0px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 The Work Order provides for CTI&amp;#x2019;s anticipated involvement in
 the study from February&amp;#xA0;1, 2013 until March&amp;#xA0;31,
 2014.&amp;#xA0;The estimated budget for the Work Order is $2,155,000,
 which is subject to change as necessary, with payments made
 throughout the term of the project as the work is performed. During
 the three and nine months ended September&amp;#xA0;30, 2013, the
 Company recognized $239,000 and $1,329,000 of expenses related to
 this agreement for services performed.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 The Agreement or any work order may be terminated for any reason by
 any party upon ninety (90)&amp;#xA0;days prior written notice to the
 other party. In addition, the Agreement may be terminated by either
 party immediately if the other party becomes insolvent, is
 dissolved or liquidated, makes a general assignment for the benefit
 of its creditors, files or has filed against it (and does not
 obtain a dismissal within ninety (90)&amp;#xA0;days)&amp;#xA0;a petition of
 bankruptcy, or has a receiver appointed for it or a substantial
 part of its assets, among other reasons. Further, the Agreement or
 any relevant work order may be terminated immediately by written
 notice from the Company, in the following circumstances:
 (1)&amp;#xA0;the FDA withdraws authorization and approval to conduct a
 study; or (2)&amp;#xA0;the Company reasonably determines that for
 medical, clinical or patient safety reasons, a study should
 terminate immediately. In addition, either party may terminate the
 Agreement or any work order for material breach upon thirty
 (30)&amp;#xA0;days&amp;#x2019; written notice specifying the nature of the
 breach, if such breach has not been substantially cured within the
 thirty (30)&amp;#xA0;day period.&lt;/p&gt;

 &lt;i&gt;Drug Discovery Program with the University of Georgia&lt;/i&gt;&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 In February 2013, the Company established a collaborative drug
 discovery program at the&amp;#xA0;Complex Carbohydrate Research
 Center&amp;#xA0;at the&amp;#xA0;University of Georgia. This program is
 focused on the discovery of new carbohydrate molecules that can be
 used in the therapy of diseases where galectin proteins play a
 major role, including cancer and inflammatory and fibrotic
 disorders. The term of the agreement is effective through
 December&amp;#xA0;31, 2013, for which the Company will provide funding
 of $154,000 during the period. The Company has paid $154,000
 related to this program through September&amp;#xA0;30, 2013. This
 agreement may be terminated by either party upon 90 days
 notice.&lt;/p&gt;
 &lt;p style="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 &lt;i&gt;Separation Agreement&lt;/i&gt;&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; text-indent:13%; font-size:10pt; font-family:Times New Roman"&gt;
 In February 2009, the Company entered into a Separation Agreement
 in connection with the resignation of David Platt, Ph.D., the
 Company&amp;#x2019;s former Chief Executive Officer and Chairman of the
 Board of Directors. The Separation Agreement provides for the
 deferral of a $1.0 million separation payment due to Dr.&amp;#xA0;Platt
 upon the earlier occurrence of any of the following milestone
 events: (i)&amp;#xA0;the approval by the Food and Drug Administration
 for a new drug application (&amp;#x201C;NDA&amp;#x201D;) for any drug
 candidate or drug delivery candidate based on the Company&amp;#x2019;s
 GM-CT-01 technology (whether or not such technology is patented),
 in which case Dr.&amp;#xA0;Platt is also entitled to a fully vested
 10-year cashless-exercise stock option to purchase at least 83,334
 shares of common stock at an exercise price not less than the fair
 market value of the common stock determined as of the date of
 grant; (ii)&amp;#xA0;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, in which case Dr.&amp;#xA0;Platt is also entitled to stock
 options on the same terms to purchase at least 50,000 shares of
 common stock; or (iii)&amp;#xA0;the renewed listing of the
 Company&amp;#x2019;s securities on a national securities exchange and
 the achievement of a market capitalization of $100 million. Payment
 upon the events (i)&amp;#xA0;and (iii)&amp;#xA0;may be deferred up to six
 months, and if the Company has insufficient cash at the time of any
 of such events, it may issue Dr.&amp;#xA0;Platt a secured promissory
 note for such amount. If the Company files a voluntary or
 involuntary petition for bankruptcy, whether or not a milestone
 event has occurred, such event shall trigger the obligation to pay
 the $1.0 million with the result that Dr.&amp;#xA0;Platt may assert a
 claim for such obligation against the bankruptcy estate. During
 2011, when it became probable that the Company could be relisted on
 a national securities exchange and eventually reach a market
 capitalization of $100 million, the Company recognized the $1.0
 million severance payment due to Dr.&amp;#xA0;Platt and it is included
 in accrued expenses at September&amp;#xA0;30, 2013 and
 December&amp;#xA0;31, 2012.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:13%; font-size:10pt; font-family:Times New Roman"&gt;
 On May&amp;#xA0;2, 2012, Dr.&amp;#xA0;Platt instituted an arbitration with
 the American Arbitration Association seeking the $1 million payment
 based on a claim that the milestone event in the Separation
 Agreement described in clause (iii)&amp;#xA0;above had occurred.
 Although the Company had listed its common stock on the Nasdaq
 Capital Markets as of March&amp;#xA0;22, 2012, the market
 capitalization since the listing had not reached $100 million when
 the arbitration was heard in October 2012. On November&amp;#xA0;1,
 2012, the arbitrator denied Dr.&amp;#xA0;Platt&amp;#x2019;s demand in all
 respects.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:13%; font-size:10pt; font-family:Times New Roman"&gt;
 On October&amp;#xA0;12, 2012, Dr.&amp;#xA0;Platt commenced a lawsuit under
 the Massachusetts Wage Act against Dr.&amp;#xA0;Traber and
 Mr.&amp;#xA0;McGauley who in their capacities as the Company&amp;#x2019;s
 Chief Executive Officer and Chief Financial Officer respectively
 can be held individually liable under the Wage Act for non-payment
 of wages. The lawsuit is based on the facts and issues raised in
 the arbitration regarding the payment of the $1.0 million
 separation payment under the Separation Agreement, and other
 unspecified &amp;#x201C;wages&amp;#x201D;. The statute provides that a
 successful claimant may be entitled to multiple damages, interest
 and attorney&amp;#x2019;s fees. Although the Company is not a party to
 the lawsuit, it plans to indemnify Dr.&amp;#xA0;Traber and
 Mr.&amp;#xA0;McGauley consistent with its obligations under the by-laws
 and applicable law, believes the lawsuit is without merit, and
 intends a vigorous defense on their behalf. On April&amp;#xA0;29, 2013,
 the Court allowed Dr.&amp;#xA0;Traber&amp;#x2019;s and
 Mr.&amp;#xA0;McGauley&amp;#x2019;s motion to dismiss. Dr.&amp;#xA0;Platt filed a
 Notice of Appeal to appeal the Court&amp;#x2019;s order allowing the
 defendants&amp;#x2019; motion to dismiss.&lt;/p&gt;
 &lt;p style="font-size:1px;margin-top:12px;margin-bottom:0px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="margin-top:0pt; margin-bottom:0pt; text-indent:13%; font-size:10pt; font-family:Times New Roman"&gt;
 On March&amp;#xA0;29, 2013, the Company instituted arbitration before
 the American Arbitration Association, seeking to rescind or reform
 the Separation Agreement discussed above. The Company claims that
 Dr.&amp;#xA0;Platt fraudulently induced the Company to enter into the
 Separation Agreement, breached his fiduciary duty to the Company,
 and was unduly enriched from his conduct. Along with removal of the
 $1.0 million milestone payment under the Separation Agreement, the
 Company is seeking repayment of all separation benefits paid to
 Dr.&amp;#xA0;Platt to date. Depending on the outcome of the
 arbitration, the previously accrued $1.0 million could be reversed.
 This arbitration has been scheduled for May 2014; however, the
 ultimate outcome is uncertain and there is no guarantee that the
 Company will be successful in this demand.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:17%; font-size:10pt; font-family:Times New Roman"&gt;
 On August&amp;#xA0;1, 2013, the market capitalization of the
 Company&amp;#x2019;s common stock exceeded $100 million and the Company
 received a letter dated October&amp;#xA0;1, 2013, demanding payment of
 the $1 million. As described in the preceding paragraph, the
 Company had previously instituted an arbitration against
 Dr.&amp;#xA0;Platt seeking to rescind the Separation Agreement,
 including the milestone payment provision. The Company expects to
 delay payment for at least six months under the terms of the
 Separation Agreement.&lt;/p&gt;
 &lt;p style="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 &lt;i&gt;Series C Post Conversion Dividend Rights&lt;/i&gt;&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; text-indent:13%; font-size:10pt; font-family:Times New Roman"&gt;
 In January 2013, 5 shares of the Company&amp;#x2019;s Series C Super
 Dividend Convertible Preferred Stock (&amp;#x201C;Series C&amp;#x201D;) were
 converted into 8,475 shares of common stock (consisting of 8,334
 shares of common stock for principal and 141 shares for accrued
 interest at the time of the conversion) which also resulted in the
 issuance of 5 Series C post-conversion dividend rights
 (&amp;#x201C;Dividend Rights&amp;#x201D;). Under the terms of the Series C,
 the Dividend Rights entitle the holder only to dividend payments
 based on actual sales of GM-CT-01 and will not participate in the
 6% dividend payable on outstanding shares of Series C following a
 conversion to common stock. At September&amp;#xA0;30, 2013, there are a
 total of 10 outstanding Dividend Rights which were determined to
 have a de minimis value, because payment of a dividend for the
 Dividend Rights is considered improbable at this time and the
 Company has not recorded a liability related to the Dividend
 Rights. The Company will continue to evaluate and assess the
 Dividend Rights for each reporting period. At September&amp;#xA0;30,
 2013, the Dividend Rights had a redemption value of $241,000.&lt;/p&gt;
 &lt;p style="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 &lt;i&gt;Other Legal Proceedings&lt;/i&gt;&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; text-indent:13%; font-size:10pt; font-family:Times New Roman"&gt;
 The Company records accruals for such contingencies to the extent
 that the Company concludes that their occurrence is probable and
 the related damages are estimable, except as noted above. There has
 been no change in the matters reported in our Annual Report on Form
 10-K for the year ended December&amp;#xA0;31, 2012.&lt;/p&gt;

 &lt;p style="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 On March&amp;#xA0;22, 2012, the Company entered into an underwriting
 agreement relating to the offer and sale of 1,159,445 units (the
 &amp;#x201C;Units&amp;#x201D;) of the Company. Each unit consisted of two
 shares of Common Stock and one warrant to purchase one share of
 Common Stock. Pursuant to the underwriting agreement, the Company
 granted the underwriters a 45-day option to purchase up to an
 additional 173,916 Units to cover over-allotments, which they
 exercised on March&amp;#xA0;26, 2012. The public offering price for
 each Unit was $9.00. Each warrant has an initial exercise price of
 $5.63 per share, is exercisable upon separation of the Units and
 expires on March&amp;#xA0;28, 2017.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 On March&amp;#xA0;28, 2012, the Company sold and issued 1,333,361 Units
 (2,666,722 shares of common stock and related $5.63 warrants to
 purchase 1,333,361 shares of common stock) for gross proceeds of
 $12.0 million (net cash proceeds of $10,403,000 after the
 underwriting discount and offering costs). The warrants were valued
 at $4,445,000 as of the issuance date of March&amp;#xA0;28, 2012, using
 the closing price of $4.20, a life of 5 years, a volatility of 119%
 and a risk free interest rate of 1.05%. Based upon the
 Company&amp;#x2019;s analysis of the criteria contained in ASC Topic
 815-40, &amp;#x201C;Derivatives and Hedging&amp;#x2014;Contracts in
 Entity&amp;#x2019;s Own Equity&amp;#x201D; the Company has determined that
 warrants issued in connection with this financing transaction were
 not derivative liabilities and therefore, were recorded as
 additional paid-in capital.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 On March&amp;#xA0;28, 2012, in connection with this underwritten
 financing as per the underwriting agreement, the Company issued a
 total of 46,378 common stock purchase warrants to the underwriters.
 These warrants expire May&amp;#xA0;2, 2016, have an exercise price of
 $5.63 per share, and are exercisable beginning 1 year from
 March&amp;#xA0;22, 2012 (the date of the underwriting agreement). These
 warrants were valued at $143,000 as of the date of issuance (March
 28, 2012), using the closing price of $4.20, life of 4.1 years,
 volatility of 117% and risk free interest rate of 0.78. Based upon
 the Company&amp;#x2019;s analysis of the criteria contained in ASC Topic
 815-40, &amp;#x201C;Derivatives and Hedging&amp;#x2014;Contracts in
 Entity&amp;#x2019;s Own Equity&amp;#x201D;, the Company has determined that

 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 Effective as of March&amp;#xA0;23, 2012, and in connection with the
 pricing of the offering of Units, the Company effected a
 one-for-six reverse split of its Common Stock. Per the terms of the
 reverse split, all fractional shares were rounded up.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman"&gt;
 On August&amp;#xA0;16, 2013, the Company issued 500,000 shares of its
 common stock for proceeds of $3,000,000 to a single investor
 pursuant to a private placement. There were no warrants or
 placement fees associated with this transaction.&lt;/p&gt;
