&lt;p style="margin-top:6px;margin-bottom:0px; text-indent:4%"&gt;
&lt;font style="font-family:Times New Roman" size="2"&gt;In April 2009,
the Company entered into agreements with consultants that provided
for the grant of warrants for the purchase of 33,333 shares of
common stock at an exercise price of $3.00 per share which will
vest upon the achievement of certain milestones. The Company valued
these warrants at $10,000 as of June&amp;#xA0;30, 2012 using the
following assumptions: expected life of 0.79 years, volatility of
78%, risk free interest rates of 0.21% and zero dividends. The
Company recognized a reversal of previously recognized expense
related to the 33,333 warrants of $45,000 and $88,000 for the three
and six months ended June&amp;#xA0;30, 2012, respectively, and an
expense of $12,000 and $20,000 for the three and six months ended
June&amp;#xA0;30, 2011, respectively.&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:12px;margin-bottom:0px; text-indent:4%"&gt;
&lt;font style="font-family:Times New Roman" size="2"&gt;In May 2010, the
Company entered into an agreement with a consultant that provided
for the grant of warrants for the purchase of 12,000 shares of
common stock at an exercise price of $15.00 per share. The
following assumptions were used to value the warrants for the six
months ended June&amp;#xA0;30, 2011: an expected life of 2.99 to 3.32
years, volatility of 128% to 130%, risk free interest rate of 0.79%
to 1.29% and zero dividends. At June&amp;#xA0;30, 2011, 45,000 warrants
were vested and 27,000 were forfeited upon cancellation of the
agreement. The company recognized an expense of $5,000 and $12,000
related to these warrants during the three and six months ended
June&amp;#xA0;30, 2011, respectively.&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:12px;margin-bottom:0px; text-indent:4%"&gt;
&lt;font style="font-family:Times New Roman" size="2"&gt;In June 2010,
the Company entered into an agreement with a consultant, who was
also a board member, which provided for the grant of warrants for
100,000 shares of common stock at an exercise price of $4.26 per
share. Of the 100,000 warrants, 25,000 vested immediately on
signing of the agreement, 25,000 were to vest at the end of one
year and the remaining 50,000 warrants were to vest based on the
achievement of certain milestones. The following assumptions were
used to value the warrants on March&amp;#xA0;7, 2011 at the date the
consultant effectively became an employee of the Company: an
expected life of 4.28 years, volatility of 135%, risk free interest
rate of 1.705% and zero dividends. Pursuant to an employment
agreement entered into in May 2011, all remaining unvested warrants
were immediately vested. The Company recognized the total remaining
expense of $127,000 related to these warrants during the six months
ended June&amp;#xA0;30, 2011.&lt;/font&gt;&lt;/p&gt;

(&amp;#x201C;PROCAPS&amp;#x201D;) (in the form of a definitive term sheet)
exclusive rights to market and sell GM-CT-01 (formerly
DAVANAT&lt;font style="font-family:Times New Roman" size="1"&gt;&lt;sup style="vertical-align:baseline; position:relative; bottom:.8ex"&gt;&amp;#xAE;&lt;/sup&gt;&lt;/font&gt;)
to treat cancer in Colombia, South America. PROCAPS is an
international, privately held pharmaceutical company based in
Barranquilla, Colombia. In October 2010, the Company received a
payment of $200,000 and shipped GM-CT-01 to PROCAPS to be used by
PROCAPS to qualify its vial filling process and to replicate the
Company&amp;#x2019;s stability study. The $200,000 payment from PROCAPS
is included as deferred revenue on the condensed consolidated
balance sheets as of June&amp;#xA0;30, 2012 and December&amp;#xA0;31, 2011.
The Company will recognize the revenue when the remaining
deliverables of the collaboration agreement have been
completed.&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:12px;margin-bottom:0px; text-indent:4%"&gt;
&lt;font style="font-family:Times New Roman" size="2"&gt;On
October&amp;#xA0;18, 2011, the Company entered into a Collaboration,
Supply, Marketing and Distribution Agreement (the
&amp;#x201C;Agreement&amp;#x201D;) with PROCAPS. The Agreement grants PROCAPS
first negotiation rights to enter into similar agreements in other
Central and South American countries. The Company is the sole
manufacturer and supplier of GM-CT-01 to PROCAPS. The Agreement
obligates PROCAPS to procure regulatory approvals necessary for the
marketing and sale of GM-CT-01 naming the Company as the owner of
such approvals to the extent permitted by law, or alternatively
hold the approvals for the Company&amp;#x2019;s benefit. PROCAPS must
pay the Company a stated fee for each dose it purchases and
royalties at an incremental rate determined by annual net sales of
GM-CT-01. The Company retains all intellectual property rights to
GM-CT-01 and related products and PROCAPS may not produce, modify,
reverse engineer, or otherwise interfere with the GM-CT-01
compound. PROCAPS may not manufacture or sell products that compete
with GM-CT-01 during the term of the Agreement and for five years
thereafter.&lt;/font&gt;&lt;/p&gt;

&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;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 three and six month periods ended
June&amp;#xA0;30, 2012 and 2011, 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:&lt;/font&gt;&lt;/p&gt;

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, 2011.&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:12px;margin-bottom:0px; text-indent:4%"&gt;
&lt;font style="font-family:Times New Roman" size="2"&gt;On
March&amp;#xA0;23, 2012, the Company effected a one-for-six reverse
stock split. All common share and per share amounts in these
financial statements have been retroactively adjusted to reflect
the effect of the reverse split. On March&amp;#xA0;28, 2012, the
Company sold 2,666,722 shares of common stock and related warrants
to purchase 1,333,361 shares of common stock for gross proceeds of
$12.0 million (net cash proceeds $10.4 million). See Note 6 for
further discussion of the transaction.&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:12px;margin-bottom:0px; text-indent:4%"&gt;
&lt;font style="font-family:Times New Roman" size="2"&gt;At June&amp;#xA0;30,
2012, the Company had $13,130,000 of unrestricted cash and cash
equivalents available to fund future operations. The Company
believes that with the cash and cash equivalents on hand at
June&amp;#xA0;30, 2012 there is sufficient cash to fund operations
through 2013. If the Company is unsuccessful in raising additional
capital or is unsuccessful in bringing its products to market
before the end of 2013, the Company may be required to cease
operations or seek bankruptcy protection.&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:12px;margin-bottom:0px; text-indent:4%"&gt;
&lt;font style="font-family:Times New Roman" size="2"&gt;As shown in the
condensed consolidated financial statements, the Company incurred
cumulative net losses applicable to common stockholders of $74.6
million for the cumulative period from inception (July 10, 2000)
through June&amp;#xA0;30, 2012. 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 June&amp;#xA0;30, 2012, the Company had
raised a net total of $68.8 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
June&amp;#xA0;30, 2012, the Company used cash of $54.7 million in its
operations.&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:12px;margin-bottom:0px; text-indent:4%"&gt;
&lt;font style="font-family:Times New Roman" size="2"&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;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:12px;margin-bottom:0px; text-indent:4%"&gt;
&lt;font style="font-family:Times New Roman" size="2"&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;/font&gt;&lt;/p&gt;

&lt;p style="margin-top:6px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;&lt;i&gt;Separation
Agreement&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:6px;margin-bottom:0px; text-indent:4%"&gt;
&lt;font style="font-family:Times New Roman" size="2"&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 severance payment due to Dr.&amp;#xA0;Platt under his
prior employment agreement until the 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 June&amp;#xA0;30, 2012 and December&amp;#xA0;31,
2011.&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:12px;margin-bottom:0px; text-indent:4%"&gt;
&lt;font style="font-family:Times New Roman" size="2"&gt;On May&amp;#xA0;2,
2012, Dr.&amp;#xA0;Platt instituted an arbitration seeking payment of
the $1.0 million severance payment based on a claim that the
renewed securities exchange listing and market capitalization
milestone event in the Separation Agreement has occurred (see
clause (iii)&amp;#xA0;above).&amp;#xA0;On March&amp;#xA0;22, 2012, the
Company&amp;#x2019;s common stock was listed on the NASDAQ Capital
Markets but since that date has not achieved the required market
capitalization. Although the Company has recorded the payment as an
accrued expense, and plans to pay if and when the milestone event
occurs according to the terms of the Separation Agreement, it
disputes Dr.&amp;#xA0;Platt&amp;#x2019;s argument that the market
capitalization component could exist before the Company relisted
its common stock, and accordingly intends to contest the
arbitration vigorously.&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:Times New Roman" size="2"&gt;&lt;i&gt;Series C Post Conversion
Dividend Rights&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:6px;margin-bottom:0px; text-indent:4%"&gt;
&lt;font style="font-family:Times New Roman" size="2"&gt;In July 2011, 5
shares of the Company&amp;#x2019;s Series C Super Dividend Convertible
Preferred Stock (&amp;#x201C;Series C&amp;#x201D;) were converted into 8,334
shares of common stock 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 but not, following a conversion to common stock,
the 6% dividend payable on outstanding shares of Series C. At
June&amp;#xA0;30, 2012, the outstanding Dividend Rights 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.&lt;/font&gt;&lt;/p&gt;
&lt;p style="font-size:1px;margin-top:12px;margin-bottom:0px"&gt;

Proceedings&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:6px;margin-bottom:0px; text-indent:4%"&gt;
&lt;font style="font-family:Times New Roman" size="2"&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. 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, 2011.&lt;/font&gt;&lt;/p&gt;

June&amp;#xA0;30, 2012, there was $6,292,000 of unrecognized
compensation related to 1,362,675 unvested options which is
expected to be recognized over a weighted&amp;#x2013;average period of
approximately 3.7 years. The weighted-average grant date fair value
for options granted during both the three and six months ended
June&amp;#xA0;30, 2012 was $1.72. The weighted-average grant date fair

vest only upon the achievement of certain market conditions (83,334

billion and $10 billion, respectively). These market condition
stock option awards were valued at $1,006,000 using a Monte Carlo
model and will be recognized over a weighted average period of 5.5
years. Assumptions used to value these options included the
following: annualized volatility of 110%, annualized
drift/risk-free interest rate of 3.5% and a forecast horizon/life
of 10 years.&lt;/font&gt;&lt;/p&gt;
