"purchase price" used to determine the per share consideration as set forth above is initially set at $94,500,000 but is subject to adjustment based, in part, on CuraGen's cash at the closing of
the merger (the calculation of which is set forth in the merger agreement). If CuraGen's cash at the closing of the merger exceeds $54,500,000, then the purchase price will be adjusted upward by $1.30
for each $1.00 of excess until the aggregate purchase price reaches $97,500,000, and thereafter by $1.00 for each $1.00 of excess up to a maximum aggregate purchase price of $100,000,000. If CuraGen's
cash at the closing of the merger is less than $54,500,000, then the purchase price will be adjusted downward by $1.00 for each $1.00 of the shortfall. A complete description of the foregoing
adjustment is set forth in the merger agreement. The merger agreement provides limits on the maximum and minimum number of shares of Celldex that will be issued pursuant to the merger. As a result,
immediately after the effective time of the merger, Celldex stockholders will retain between 67.5% and 42% of Celldex's outstanding shares of common stock. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
behalf of the board of directors of Celldex Therapeutics,&nbsp;Inc., a Delaware corporation ("Celldex"), we are pleased to deliver this joint proxy statement/prospectus for the
proposed merger combining a wholly-owned subsidiary of Celldex with and into CuraGen Corporation, a Delaware corporation ("CuraGen"). A special meeting of stockholders of Celldex will be held on
[&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;], 2009 at [&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;], local time, at the offices of Lowenstein Sandler PC,

be amended from time to time, which will result in the issuance of shares of Celldex common stock equal to at least 32.5%, and no more than 58%, of the sum of the total number of shares of Celldex
common stock outstanding immediately after the effective time of the merger (which number includes the shares of CuraGen common stock outstanding immediately prior to the effective time of the merger
that are converted into shares of Celldex common stock in the merger) <U>plus</U> the maximum number of shares of Celldex common stock issuable upon exercise of CuraGen options

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
board of directors of Celldex has fixed [&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;], 2009 as the record date for the determination of stockholders entitled to notice of,
and to vote
at, the special meeting and any adjournment or postponement thereof. Only record holders of shares of Celldex common stock at the close of business on the record date are entitled to notice of, and to
vote at, the special meeting. At the close of business on the record date, Celldex had [&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;]&nbsp;shares of common stock outstanding and entitled to vote.
</FONT></P>


<P style="font-family:times;"><FONT SIZE=2><B>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Your vote is important.</B></FONT><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;We cannot complete the transactions contemplated by the merger agreement without the affirmative vote of the
holders of a
majority of the votes cast in person or by proxy at the Celldex special meeting in favor of the approval of Proposal No.&nbsp;1. Even if you plan to attend the special meeting in person, we request
that you sign and return the enclosed proxy card or submit a proxy by telephone or via the internet and thus ensure that your shares will be represented at the special meeting if you are unable to
attend. If you sign, date and mail your proxy card or submit a proxy by telephone or via the internet without indicating how you wish to vote, your proxy will be counted as a vote in favor of Proposal
Nos.&nbsp;1 and 2. If you fail to submit a proxy, your shares will not be counted for purposes of determining whether a quorum is present at the special meeting. If you do attend the Celldex special
meeting and wish to vote in person, you may withdraw your proxy and vote in person. </FONT></P>

$54,500,000, then the purchase price will be adjusted upward by $1.30 for each $1.00 of excess until the aggregate purchase price reaches $97,500,000, and thereafter by $1.00 for each $1.00 of excess

The parties have agreed to a collar on the exchange ratio&#151;meaning that the aggregate number of shares of common stock Celldex will issue pursuant to the merger
(including shares issuable upon exercise of CuraGen in-the-money options assumed by Celldex in the merger) will not be more than 58%, nor less than 32.5%, of the sum of the total number of shares of
Celldex common stock outstanding immediately after the effective time of the merger (which number includes the shares of CuraGen common stock outstanding immediately prior to the effective time of the
merger that are converted into shares of Celldex common stock in the merger) <U>plus</U> the maximum number of shares of Celldex common stock issuable upon exercise of CuraGen
in-the-money options assumed by Celldex in the merger. That means that if the closing price of Celldex's common stock (determined by the calculation described in the question above) is less than $4.33
(assuming a $94.5&nbsp;million purchase price and 15,820,593 shares of Celldex common stock outstanding immediately after the effective time of the merger, excluding shares issued or issuable by
Celldex pursuant to the merger), the number of shares of Celldex common stock issuable in the merger (including shares issuable upon exercise of CuraGen in-the-money options assumed by Celldex in the
merger) would be fixed at 21,847,486. Conversely, if the closing price of Celldex's shares determined by the calculation described above is greater than $12.41 (assuming a $94.5&nbsp;million
purchase price and 15,820,593 shares of Celldex common stock outstanding immediately after the effective time of the merger, excluding shares issued or issuable by Celldex pursuant to the merger), the
number of shares of Celldex common stock issuable in the merger (including shares issuable upon exercise of CuraGen in-the-money options assumed by Celldex in the merger) would be fixed at 7,617,323

meeting of stockholders to be held on [&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;], 2009 and vote your shares in person, rather than signing and
returning your proxy card or otherwise providing proxy
instructions. If you are a beneficial owner of shares held in street name, you must obtain a legal proxy from your broker, bank or nominee and present it to the inspectors of election with your ballot
when you vote at the meeting. </FONT> <FONT SIZE=2><B> <BR><BR> </B></FONT></DD><DT style='font-family:times;margin-bottom:-11pt;'><FONT SIZE=2><B>Q:</B></FONT></DT><DD style="font-family:times;"><FONT SIZE=2><B> May I change my vote after I have submitted a proxy or voting instructions?  </B></FONT><FONT SIZE=2>

You may change your vote at any time before your proxy is voted at the applicable special meeting of stockholders. If you are a stockholder of record, you can do this in one of
three ways. First, you can send a written notice stating that you would like to revoke your proxy. Second, you can submit new proxy instructions either on a new proxy card, by telephone or via the
Internet. Third, you can attend the meeting and vote in person. Your attendance at your special meeting alone will not revoke your proxy. If you have instructed a broker, bank or other nominee to vote
your shares of common stock, you must follow directions received from your broker, bank or other nominee to change those instructions. </FONT> <FONT SIZE=2><B> <BR><BR> </B></FONT></DD><DT style='font-family:times;margin-bottom:-11pt;'><FONT SIZE=2><B>Q:</B></FONT></DT><DD style="font-family:times;"><FONT SIZE=2><B> Am I

CuraGen's common stock is quoted on the NASDAQ Global Market and CuraGen's stockholders will be entitled to receive shares of Celldex common stock pursuant to the merger (plus cash
in lieu of fractional shares). Therefore, pursuant to the General Corporation Law of the State of Delaware, CuraGen stockholders will not be entitled to appraisal rights. </FONT> <FONT SIZE=2><B> <BR><BR> </B></FONT></DD><DT style='font-family:times;margin-bottom:-11pt;'><FONT

<BR><BR></FONT></DD><DT style='font-family:times;margin-bottom:-11pt;'><FONT SIZE=2>A:</FONT></DT><DD style="font-family:times;"><FONT SIZE=2>Generally,
no. The merger is intended to qualify as a "reorganization" within the meaning of Section&nbsp;368(a) of the United States Internal Revenue Code of 1986, as amended (the
"Code"). Assuming the merger qualifies as a reorganization, the holders of CuraGen common stock generally will not recognize any gain or loss for United States federal income tax purposes on the
exchange of shares of CuraGen common stock shares for shares of Celldex common stock pursuant to the merger, except with respect to cash received in lieu of fractional shares of Celldex common stock.
Further, assuming the Merger qualifies as a reorganization, neither Celldex, CuraGen nor Cottrell Merger Sub,&nbsp;Inc. will recognize any gain or loss for United States federal income tax purposes
as a result of the merger. You should read the section entitled "Celldex Proposal&nbsp;1 and CuraGen Proposal&nbsp;1: The Merger&#151;Material United States Federal Income Tax Consequences
of the Merger" commencing on page&nbsp;60 for a more complete discussion of the United States federal income tax consequences of the merger. </FONT><FONT SIZE=2><B>Tax matters can be complicated
and the tax consequences of the merger to you will depend on your particular tax situation. We urge you to consult your tax advisor to determine the tax consequences of the merger to

Piper&nbsp;Jaffray's opinion was provided to the CuraGen board of directors in connection with its evaluation of the merger consideration, did not address any other aspect of the merger, the merger
agreement, any related agreements or agreement ancillary thereto, and did not constitute a recommendation to the CuraGen board of directors or to any stockholder as to how to vote or act in connection

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;When considering the recommendation of Celldex's board of directors and in considering how to vote on the issuance of shares of Celldex
common stock pursuant to the merger agreement, you should be aware that Celldex's directors and executive officers have interests in
the merger which may be additional to, or different from the interests of Celldex's stockholders, and that may create potential or actual conflicts of interest. Together, upon completion of the merger
the current directors and officers of Celldex will collectively beneficially own approximately [&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;]% of the outstanding stock of Celldex. Upon completion of the
merger, the current directors of Celldex are expected to remain members of the Celldex board of directors, specifically: Herbert J. Conrad, Larry Ellberger, George O. Elston, Karen Shoos Lipton,
Anthony S. Marucci, Rajesh B. Parekh, Harry H. Penner, and Charles R. Schaller. Celldex's board of directors was aware of these interests and considered them, among other matters, in approving the
issuance of shares of Celldex common stock pursuant to the merger agreement and recommending that Celldex's stockholders vote to approve such issuance. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;CuraGen
has agreed that it will not, and has further agreed to ensure that its representatives do not, prior to the completion of the merger, directly or indirectly, initiate, solicit,

any inquiries, proposals or offers regarding, or approve, adopt or recommend, any acquisition, merger, take-over bid, sale of substantial assets, sale of shares of capital stock (including
without limitation by way of a tender offer) or similar transactions. However, if prior to the adoption of the merger agreement by its stockholders, CuraGen receives an unsolicited bona fide written
acquisition proposal that, in the good faith judgment of CuraGen's board, would be or is reasonably likely to lead to a superior acquisition proposal, then CuraGen may provide nonpublic information
to, and engage in discussions and negotiations with, the third party making the acquisition proposal so long as certain conditions are satisfied. CuraGen may also terminate the merger agreement in

al.</I></FONT><FONT SIZE=2>, was filed in the Connecticut Superior Court, Judicial District of New Haven, on June&nbsp;9, 2009. A second
putative class action complaint, </FONT><FONT SIZE=2><I>Cheryl Smith v. CuraGen Corporation, et al.</I></FONT><FONT SIZE=2>, was filed in the Court of Chancery of the State of Delaware on
June&nbsp;15, 2009. Both lawsuits purport to be brought on behalf of all public stockholders of CuraGen, and name CuraGen, all of its directors, Celldex, and Cottrell Merger Sub as defendants. The
complaints allege, among other things, that the merger consideration to be paid to CuraGen stockholders in the merger is unfair and undervalues CuraGen. In addition, the complaints allege that
CuraGen's directors violated their fiduciary duties by, among other things, failing to maximize stockholder value and failing to engage in a fair sale process. The complaints also allege that CuraGen
and Celldex aided and abetted the alleged breaches of fiduciary duties by CuraGen's directors. The complaints seek, among other relief, an injunction preventing completion of the merger or, if the
merger is consummated, rescission of the merger. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;These

CuraGen's assets, liabilities and other items will be adjusted to their estimated fair value on the closing date of the merger and combined with the historical book values of the assets and
liabilities of Celldex. The difference between the estimated fair value of CuraGen's assets, liabilities and other items (adjusted as discussed above) and the purchase price will be recorded as
goodwill on the financial statements of Celldex. The financial statements of Celldex issued after the merger will reflect the estimated fair values of CuraGen's assets, liabilities and other items

<P style="font-family:times;"><FONT SIZE=2><B> Because certain of the components of the exchange ratio will fluctuate prior to closing, CuraGen's and Celldex's stockholders cannot be certain of the value of the merger
consideration or their percentage ownership of the combined company following the merger.  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Upon completion of the merger, each share of CuraGen common stock will be converted into the right to receive a number of shares of
Celldex's common stock in accordance with an exchange ratio calculated based upon a formula described in the section entitled "The Merger Agreement&#151;The Exchange Ratio" commencing on
page&nbsp;78. Because the exchange ratio formula is based in part on CuraGen's net cash and related resources at the time of the closing, as well as the average market price of Celldex's stock over
a period of time prior to the closing, it will be impossible to determine at the time of the CuraGen and Celldex stockholder meetings the precise value of the merger consideration payable in respect
of each share of CuraGen common stock, the number of shares of Celldex common stock that will be issued pursuant to the merger, or the percentage of the combined company that will be owned by former
CuraGen stockholders immediately after the effective time of the merger. However, the merger agreement provides that, to the extent the exchange ratio formula would require Celldex to issue shares of
its common stock pursuant to the merger (including shares issued upon exercise of CuraGen in-the-money options assumed by Celldex in the merger) equal to more than 58% of the sum of the total number
of shares of Celldex common stock outstanding immediately after the effective time of the merger (which number includes the shares of CuraGen common stock outstanding immediately prior to the
effective time of the merger that are converted into shares of Celldex common stock in the merger) <U>plus</U> the maximum number of shares of Celldex common stock issuable upon
exercise of CuraGen in-the-money options assumed by Celldex in the merger, the exchange ratio will become fixed so that Celldex will issue pursuant to the merger shares
constituting 58% of such number of shares. Similarly, the merger agreement provides that, to the extent the exchange ratio would require Celldex to issue shares of Celldex's common stock pursuant to
the merger (including shares issued upon exercise of CuraGen in-the-money options assumed by Celldex in the merger) equal to less than 32.5% of the sum of the total number of shares of Celldex common
stock outstanding immediately after the effective time of the merger (which number includes the shares of CuraGen common stock outstanding immediately prior to the effective time of the merger that

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Neither
Celldex nor CuraGen is permitted to terminate the merger agreement or re-solicit the vote of its stockholders solely because of changes in the market prices of either
company's stock or CuraGen's net cash and related resources at closing. There will be no adjustment to the exchange ratio formula for changes in the market price of shares of CuraGen or Celldex common
stock. Stock price changes may result from a variety of factors, including general market and economic conditions, changes in Celldex's or CuraGen's business, operations and prospects, and regulatory
considerations. Many of these factors are beyond Celldex's and CuraGen's control. You should obtain current market quotations for shares of Celldex common stock and for shares of CuraGen common stock. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><B> Each of Celldex and CuraGen will be subject to business uncertainties and contractual restrictions while the merger is pending.  </B></FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Uncertainty about the effect of the merger on employees and customers may have an adverse effect on CuraGen and consequently on
Celldex. These uncertainties may impair CuraGen's ability to attract, retain and motivate key personnel until the merger is consummated, and could cause customers and others that deal with CuraGen to
seek to change existing business relationships with CuraGen. Retention of certain employees may be challenging during the pendency of the merger, as certain employees may experience uncertainty about
their future roles with Celldex. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with Celldex, Celldex's business

occurs without the consent of the other party. These restrictions may prevent each of Celldex and CuraGen from pursuing attractive business opportunities that may arise prior to the completion of the

addition to the restrictions described above, CuraGen is prohibited from soliciting or entering into an acquisition proposal with a third party during the pendency of the merger, but
CuraGen has the right to terminate the merger agreement in connection with a superior proposal. Please see the section entitled "Celldex Proposal&nbsp;1 and CuraGen Proposal&nbsp;1: The

anticipation of FDA approval of these products, Celldex will need to make substantial investments to establish sales, marketing, quality control, and regulatory compliance
capabilities. These investments will increase if and when any of these products receive FDA approval. Celldex cannot predict how quickly its lead products will progress through the regulatory approval

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The market price of Celldex's common stock has historically experienced and may continue to experience significant volatility. From
June 2008 through May 2009, the market price of Celldex's common stock has fluctuated from a high of $19.79 per share in the second quarter of 2008, to a low of $4.24 per share in the fourth quarter
of 2008. Celldex's progress in developing and commercializing its products, the impact of government regulations on Celldex's products and industry, the potential sale of a large volume of Celldex's
common stock by selling stockholders, Celldex's quarterly operating results, changes in general conditions in the economy or the financial markets and other developments affecting Celldex or its
competitors could cause the market price of Celldex's common stock to fluctuate substantially. In addition, in recent years, the stock market has experienced significant price and volume fluctuations.
This volatility has affected the market prices of securities issued by many companies for reasons unrelated to their operating performance and may adversely affect the price of Celldex's common stock.
In addition, Celldex could be subject to a securities class action litigation as a result of volatility in the price of Celldex's stock, which could result in substantial costs and diversion of
management's attention and Celldex's resources, which could harm Celldex's stock price, business prospects, results of operations and financial condition. </FONT></P>

2004 and as of December&nbsp;31, 2006, 2005 and 2004 is derived from Celldex's audited historical consolidated or combined financial statements, which are not included or incorporated by reference
into this joint proxy statement/prospectus. The consolidated financial information as of and for the three-month periods ended March&nbsp;31, 2008 and 2009 is derived from Celldex's unaudited
consolidated financial statements incorporated by reference into this joint proxy statement/prospectus. In Celldex's opinion, such unaudited consolidated financial statements include all adjustments
(consisting of normal recurring adjustments) necessary for a fair presentation of its financial position and results of operations for such
periods. Interim results for the three months ended March&nbsp;31, 2009 are not necessarily indicative of, and are not projections for, the results to be expected for the full year ending
December&nbsp;31, 2009. For more information regarding Celldex, see "Where You Can Find More Information" commencing on page&nbsp;105. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
selected historical financial data below should be read in conjunction with the consolidated or combined financial statements and their accompanying notes that are incorporated by
reference into this document. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
March&nbsp;7, 2008, the merger between Celldex (formerly known as AVANT Immunotherapeutics,&nbsp;Inc., "AVANT") and Celldex Research Corporation (formerly known as Celldex
Therapeutics,&nbsp;Inc., "Celldex Research"), became effective. The merger was accounted for using the purchase method of accounting and was treated as the acquisition of AVANT, a publicly
registered company, by Celldex Research, a private company. Accordingly, the financial information presented below for periods prior to March&nbsp;8, 2008 reflects the financial position and the
results of operations of Celldex Research alone, and for periods from March&nbsp;8, 2008 forward the combined financial position and combined results of operations of AVANT and Celldex Research.
AVANT changed its name to Celldex Therapeutics,&nbsp;Inc. on October&nbsp;1, 2008. All amounts are in thousands except per share data. </FONT></P>

selected historical financial data for the years ended December&nbsp;31, 2006, 2007 and 2008 should be read in conjunction with CuraGen's "Management's Discussion and Analysis of

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The following unaudited pro forma condensed combined financial statements give effect to the merger of Celldex and CuraGen in a
transaction to be accounted for under the acquisition method of accounting in accordance with Statement of Financial Accounting Standards ("SFAS") No.&nbsp;141(R), Business Combinations (Revised)
("SFAS&nbsp;141(R)"), with Celldex treated as the acquirer and surviving legal entity in the transaction. The unaudited pro forma condensed combined balance sheet is based on the individual
historical consolidated balance sheets of Celldex and CuraGen as of March&nbsp;31, 2009, and has been prepared to reflect the merger of Celldex and CuraGen as of March&nbsp;31, 2009. The unaudited
pro forma condensed combined statements of operations are based on the individual historical consolidated statements of operations of Celldex and CuraGen and combine the results of operations of
Celldex and CuraGen for the year ended December&nbsp;31, 2008 and the three months ended March&nbsp;31, 2009, giving effect to the merger as if it occurred on January&nbsp;1, 2008 for both pro
forma statements of operations, reflecting only pro forma adjustments expected to have a continuing impact on the combined results. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;These
unaudited pro forma condensed combined financial statements are for informational purposes only. They do not purport to indicate the results that would have actually been obtained
had the merger been completed on the assumed date or for the periods presented, or which may be realized in the future. To produce the pro forma financial information, Celldex allocated the purchase
price using its best estimates of fair value. These estimates are based on the most recently available information. To the extent there are significant changes to Celldex's or CuraGen's business,
including results from ongoing clinical trials, the assumptions and estimates herein could change significantly. The allocation is dependent upon certain valuation and other studies that are not yet
final. Accordingly, the pro forma purchase price adjustments are preliminary, subject to further adjustments as additional information becomes available and as additional analyses are performed. Upon
completion of the merger, final valuations will be performed. There can be no assurances that these final valuations will not result in material changes to the purchase price allocation. Furthermore,
the parties expect to have reorganization and restructuring expenses as well as potential operating efficiencies as a result of combining the companies. The pro forma financial information does not
reflect these potential expenses and efficiencies, except for the CuraGen severance obligation described below. The unaudited pro forma condensed combined financial statements should be read in
conjunction with: </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On May&nbsp;28, 2009, Celldex and CuraGen signed an Agreement and Plan of Merger under which a wholly owned subsidiary of Celldex will merge with and into
CuraGen in a transaction to be accounted for under the acquisition method of accounting in accordance with accounting principles generally accepted in the United States of America, with Celldex
treated as the accounting acquirer. Under the acquisition method of accounting, all of CuraGen's assets acquired and liabilities assumed in the transaction will be recorded by Celldex at their
acquisition date fair values while transaction costs associated with the transaction are expensed as incurred. The transaction is intended to qualify as a reorganization within
the meaning of Section&nbsp;368(a) of the Code. Under the terms of the merger agreement, each share of CuraGen common stock outstanding at the closing of the merger will be exchanged for shares of
Celldex common stock at an exchange ratio (the "Common Stock Exchange Ratio") determined as set forth in the merger agreement, plus cash in lieu of a fractional share of Celldex Common Stock. In
addition, each option to purchase CuraGen common stock issued under the 2007 Stock Plan that is outstanding on the closing date ("CuraGen 2007 Options") will be assumed by Celldex and will thereafter
constitute an option to acquire the number of shares of Celldex common stock determined by multiplying the number of shares of CuraGen common stock subject to the option immediately prior to the
merger by the Common Stock Exchange Ratio, rounded down to the nearest whole share, with an exercise price equal to the exercise price of the assumed CuraGen option divided by the Common Stock
Exchange Ratio, rounded up to the nearest whole cent. Each of these assumed options will be subject to the same terms and conditions that were in effect for the related CuraGen options. The merger is
subject to certain closing conditions, including approval by Celldex and CuraGen stockholders. </FONT></P>

fair value of the Celldex shares used in determining the purchase price was $8.13 per share based on the closing price for Celldex common stock on May&nbsp;28, 2009, the date prior
to the acquisition agreement announcement date. In accordance with SFAS&nbsp;141(R), the fair value of the Celldex shares issued as part of the consideration transferred will be measured using the
market price of Celldex common stock on the closing date. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;SFAS&nbsp;141(R)
requires that the fair value of replacement awards attributable to precombination service be included in the consideration transferred. Approximately 97% of the
CuraGen 2007 Options immediately vest upon change of control and 100% of the CuraGen 2007 Options immediately vest upon the employment termination of the option holder as a result of a change of
control. For purposes of preparing the pro forma condensed combined financial statements, Celldex has assumed that all CuraGen employees will be terminated, as discussed below under CuraGen Severance
Obligations, and that all CuraGen 2007 Options will immediately vest at the effective time of the merger. The fair value of the CuraGen 2007 Options has been attributed to precombination service and
included in the consideration transferred. </FONT></P>

estimated fair value attributed to in-process research and development ("IPR&amp;D") intangible assets represents an estimate of the fair value of purchased
in-process technology for CuraGen's research programs that, as of the expected closing date of the merger, will not have reached technological feasibility and have no alternative future
use. Only those research programs that had advanced to a stage of development where management believed reasonable net future cash flow forecasts could be prepared and a reasonable likelihood of
technical success existed were included in the estimated fair value. Accordingly, the IPR&amp;D programs primarily represent the estimated fair value of CuraGen's CR011 programs. The estimated fair value
of the IPR&amp;D programs was determined based on estimates of expected future net cash flows. These expected future net cash flows included estimates for revenue and associated costs for the IPR&amp;D
programs based on (i)&nbsp;relevant industry factors, (ii)&nbsp;current and expected trends in the product development life cycle, (iii)&nbsp;the ability to engage a strategic partner,

the products. The probability-adjusted future net cash flows which reflect the different stages of development of each program are then present valued utilizing an estimate of the
appropriate discount rate which is consistent with the uncertainties of the cash flows utilized. Finally, the expected future net cash flows were calculated assuming the Amgen Amendment (defined
below) was not entered into because the fair value attributable to the Amgen Amendment is separated from the fair value of the IPR&amp;D programs. At the time of the preparation of the unaudited pro forma
condensed combined financial statements, Celldex does not have complete information as to the amount, timing and risk of the net cash flows. For purposes of preparing the unaudited pro forma condensed
combined financial statements, Celldex used publicly available information, market participant assumptions, CuraGen's existing cost and development assumptions, and certain other
high-level assumptions. </FONT></P>

will periodically evaluate these IPR&amp;D indefinite-life intangible assets. If a project is completed, the carrying value of the related intangible asset will be
amortized over the remaining estimated life of the asset beginning in the period in which the project is completed. If a project becomes impaired or is abandoned, the carrying value of the related
intangible asset will be written down to its fair value and an impairment charge will be taken in the period in which the impairment occurs. These intangible assets will be tested for impairment on an
annual basis, or earlier if impairment indicators are present. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
estimated fair value attributed to the May 2009 amendment to the CuraGen and Amgen (successor in-interest to Abgenix) license agreement relates to CuraGen's exclusive
rights to develop and commercialize CR011 and 11 other licensed antigens ("Amgen Amendment"). Under the Amgen Amendment, CuraGen and Amgen agreed to modify the terms of their existing cross-license of
antigens whereby the amended license would be fully paid-up and royalty-free (except for any potentially required payments by CuraGen to the original licensor of CR011). The
estimated fair value of the Amgen Amendment was based on the increase in expected future net cash flows for the IPR&amp;D programs related to CR011 after the Amgen Amendment was entered into as compared
to the expected future net cash flows if the Amgen Amendment was not entered into. The estimated fair value attributed to the Amgen Amendment will be amortized over its estimated useful life of
approximately 16&nbsp;years on a straight-line
basis (no other method was deemed preferable) from the expected closing date of the merger through the date of the last expiring patent covering CR011. </FONT></P>

</UL>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;All of CuraGen's employees are eligible for severance payments upon termination of employment under certain circumstances, including
following a merger. Following the merger with Celldex, any or all of CuraGen's employees may continue to be employed by Celldex. The merger agreement requires Celldex to notify CuraGen of the identity
of the employees to whom it intends to make offers of employment no less than 40 business days prior to closing. However, no employment terms were negotiated in advance of the signing of the merger
agreement, and the merger is not conditioned on any such arrangements. SFAS&nbsp;141(R) requires severance obligations that are incurred by the acquiree for the benefit of the acquirer to be
recognized as an expense in the post-combination period. Because the offer of employment is at the option of Celldex, Celldex has deemed the severance obligations to be at its benefit. For purposes of
preparing the unaudited pro forma condensed combined financial statements, because no offers have been made or accepted, Celldex has assumed that (i)&nbsp;all CuraGen employees will be terminated
and (ii)&nbsp;no severance payouts will be made prior to the effective time of the merger. This results in an increase to retained earnings and accrued liabilities in the unaudited pro forma
condensed financial statements. Celldex has allocated estimated severance obligation of $4.7&nbsp;million from total consideration transferred as an expense and accrued liability in the
post-combination period. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The following table sets forth selected historical share information of Celldex and CuraGen and unaudited pro forma
share information after giving effect to the merger between Celldex and CuraGen, assuming that 11,624 shares of Celldex common stock had been issued in exchange for each outstanding share of CuraGen
common stock. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This
assumption is based on an estimate of the exchange ratio assuming that Celldex's stock price is $8.13 (which is the closing price for Celldex's
shares on May&nbsp;28, 2009 the date prior to the acquisition agreement announcement date) and that CuraGen's cash at closing will be $54.5&nbsp;million, resulting in a purchase price of
$94.5&nbsp;million and an exchange ratio of 0.1913406. The pro forma equivalent information of CuraGen was derived using the historical share information assuming that 11,624 shares of Celldex
common stock had been issued in exchange for each outstanding share of CuraGen common stock. You should read this information in conjunction with the selected historical financial information, the
unaudited pro forma condensed combined financial statements and the separate historical financial statements of Celldex and CuraGen and the notes thereto included elsewhere in or incorporated by

Celldex stockholder who has submitted a proxy may revoke it at any time before it is voted at the Celldex special meeting by executing and returning a proxy bearing a later date,
providing proxy instructions&nbsp;via the telephone or the Internet (your latest telephone or Internet proxy is counted), filing written notice of revocation with the Secretary of Celldex stating
that the proxy is revoked or attending the special meeting and voting in person. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In addition to solicitation by mail, the directors, officers, employees and agents of Celldex may solicit proxies from Celldex's
stockholders by personal interview, telephone, or otherwise. Celldex will bear the costs of the solicitation of proxies from its stockholders. Arrangements will also be made with brokerage firms and
other custodians, nominees and fiduciaries who are record holders of Celldex common stock for the forwarding of solicitation materials to the beneficial owners of Celldex common stock. Celldex will
reimburse these brokers, custodians, nominees and fiduciaries for the reasonable out-of-pocket expenses they incur in connection with the forwarding of solicitation materials.
Celldex has retained Georgeson&nbsp;Inc. to assist in soliciting proxies for the meeting for an estimated cost of $7,500 plus out of pocket expenses. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;CuraGen's board of directors believes that the terms of the merger agreement and the proposed merger are advisable and in the best
interests of CuraGen and its stockholders. </FONT><FONT SIZE=2><B>CuraGen's board of directors approved the merger agreement and unanimously recommends that you vote FOR the adoption of the merger

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;CuraGen's board of directors has fixed the close of business on [&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;], 2009 as the record date for
the CuraGen special meeting. Accordingly, only CuraGen's stockholders of record at the close of business on such date will be entitled to notice of and to vote at the CuraGen special meeting. Brokers
or other nominees who hold shares of our common stock in "street name" for customers who are the beneficial owners of those shares may not give a proxy to vote those customers' shares in the absence
of specific instructions from those
customers, resulting in broker "non-votes." On the record date, there were [&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;] shares of CuraGen common stock outstanding, held of
record by
approximately [&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;] registered holders. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
presence, in person or by proxy, of the holders of a majority of CuraGen's outstanding shares of common stock entitled to vote, as of the record date, will constitute a quorum for
the conduct of business at the CuraGen special meeting. Both abstentions and broker "non-votes" will be counted as present for purposes of determining the existence of a quorum. In the
event a quorum is not present at the CuraGen special meeting, CuraGen may propose adjournment of the CuraGen special meeting to solicit additional proxies. </FONT></P>

the merger agreement. Abstentions, the failure to submit an executed proxy by mail, fax, telephone or through the Internet or to vote in person at the CuraGen special meeting, and broker
non-votes have the effect of a vote "AGAINST" the adoption of the merger agreement. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
there is less than a quorum present at the CuraGen special meeting, the affirmative vote of the holders of a majority of CuraGen's outstanding shares of common stock present and
entitled to vote at the special meeting is required to approve the adjournment of the special meeting for the purpose of soliciting additional proxies if there are not sufficient votes at the time of
the CuraGen special meeting to adopt the merger agreement. If there is a quorum, approval of the adjournment requires the affirmative vote of the holders of a majority of the shares representing votes
cast affirmatively or negatively. Thus, if there is less than a quorum, an abstention will have the same effect as a vote "AGAINST" the proposal to adjourn the special meeting for the purpose of
soliciting additional proxies if there are not sufficient votes at the time of the CuraGen special meeting to adopt the merger agreement. If there is a quorum, an abstention will have no effect on the
outcome of the proposal. A failure to vote at the CuraGen special meeting or to submit an executed proxy by mail, fax, telephone or through the Internet, or a broker non-vote will have no
effect on the outcome of the proposal to adjourn the CuraGen special meeting to solicit additional proxies if there are not sufficient votes at the time of the CuraGen special meeting to adopt the
merger agreement. </FONT></P>

Internet and telephone voting procedures for submitting a proxy are designed to authenticate CuraGen stockholders' identities, to allow CuraGen stockholders to have their shares voted and to
confirm that their instructions have been properly recorded. CuraGen stockholders submitting proxies or voting instructions&nbsp;via the Internet should understand that there may be costs associated
with electronic access, such as usage charges from Internet access providers and telephone companies that would be borne by the CuraGen stockholder. Please note that there are separate arrangements
for submitting voting instructions if your shares are registered in CuraGen's stock records in the name of a broker, bank, or other nominee and held on your behalf in street name. CuraGen
stockholders, who own shares through a broker, bank or other nominee, should check the instructions forwarded by their broker, bank or other holder of record to see which methods are available for
submitting voting instructions. </FONT></P>

stockholder of record who has executed a proxy but is present at the CuraGen special meeting and who wishes to vote in person, may do so and by so doing will revoke any prior proxy such stockholder
had made. CuraGen Shares represented by validly submitted proxies, received in time for use at the CuraGen special meeting and not revoked at or prior to the CuraGen special meeting, will be voted at

statement/prospectus to such stockholders, will be borne by CuraGen. In addition, CuraGen will reimburse brokerage firms and other persons representing beneficial owners of CuraGen common stock for
their expenses in forwarding proxy material to such beneficial owners. Solicitation of proxies by mail may be supplemented by telephone, facsimile, email and personal solicitation by CuraGen's
directors, officers or employees. No additional compensation will be paid for such solicitation. In addition, CuraGen may request banks, brokers, and other custodians, nominees and fiduciaries to
solicit customers of theirs who have CuraGen shares registered in the name of the nominee. CuraGen will reimburse any such persons for their reasonable out-of-pocket expenses.
CuraGen has retained Laurel Hill Advisory Group,&nbsp;LLC, a proxy solicitation firm, to assist in the solicitation of proxies for CuraGen's special meeting for a fee of approximately $7,500 plus

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As part of its evaluation of its business, CuraGen regularly considers opportunities for certain business combinations and other
strategic transactions in order to enhance stockholder value. In particular, throughout 2008 and through May 2009, CuraGen, with the assistance of several different financial and strategic advisors,
evaluated a range of strategic alternatives for the company, including a sale of the company as a whole, a sale or licensing transaction with respect to CR011, liquidating the company and distributing
the proceeds to stockholders, and acquiring new assets or businesses. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Following
the sale of its belinostat asset in the second quarter of 2008, CuraGen was approached over the remainder of the year by several companies expressing interest in an acquisition
of CuraGen, a merger of equals, or an acquisition of an existing product or entity by CuraGen. Celldex and Party A were among the companies with whom CuraGen met in person or by phone several times
during the remainder of 2008. The focus of the meetings was primarily due diligence with respect to CuraGen's business and assets. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;12, 2008, Celldex and CuraGen entered into a confidentiality agreement with respect to any confidential information shared with the other. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;23, 2008, members of Celldex and CuraGen management held an introductory meeting at CuraGen's offices in Branford, Connecticut, during which they reviewed their respective
business operations and, at a high level, their respective clinical and pre-clinical development programs. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
June&nbsp;11, 2008 and June&nbsp;24, 2008, members of Celldex and CuraGen management met again to discuss their respective clinical and preclinical development programs in further
detail. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
July&nbsp;8, 2008, members of Celldex and CuraGen management participated in a conference call to review certain financial information regarding the companies. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
September&nbsp;15, 2008, Celldex's board of directors authorized Celldex to propose a non-binding letter of intent to acquire CuraGen, which Celldex and CuraGen executed
on October&nbsp;2, 2008. The letter of intent provided for the acquisition of CuraGen by Celldex for consideration of up to $100,000,000, payable in shares of Celldex common stock. The valuation
ascribed to CuraGen in the non-binding letter of intent was explicitly conditioned on CuraGen having net cash at the closing of the transaction of no less than $65,000,000 (for purposes of
this description, "net cash" means CuraGen's cash resources net of, among other things, the par value of CuraGen's outstanding convertible securities and any other indebtedness, severance payments to
executives, transaction and any other change of control expenses and other current liabilities as of the closing of the transaction) and reflected a technology value of between $25,000,000 and
$35,000,000, subject to completion of Celldex's due diligence on CuraGen's clinical and pre-clinical programs. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
October&nbsp;10, 2008, Lowenstein Sandler PC ("Lowenstein"), outside counsel to Celldex, sent a draft merger agreement based on the letter of intent to CuraGen's outside counsel,
Wilmer Cutler Pickering Hale and Dorr&nbsp;LLP ("WilmerHale"). That draft merger agreement included a cap on the amount of stock that Celldex would be required to issue in connection with the
acquisition, such that the stockholders of CuraGen would not own more than a to-be-determined percentage of the outstanding Celldex common stock immediately following the
closing. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
October&nbsp;15, 2008, CuraGen and Celldex held a meeting to discuss the proposed transaction. At the conclusion of the meeting, Celldex and CuraGen agreed to terminate discussions
concerning a transaction because the parties could not reach agreement on price. In addition, even if the price issues could be resolved, following the decline in global capital markets that occurred
in the third quarter of 2008, the parties believed that Celldex's then-current stock price would not support a mutually </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
November 2008, CuraGen had introductory meetings with Party B and Party C, each of whom expressed interest in a potential acquisition of CuraGen. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
late December 2008, a board member of Party A approached a board member of CuraGen expressing interest in resuming discussions, but no terms were proposed at that time. It was agreed
that the possibility of resuming discussions with Party A would be discussed by the CuraGen board at its meeting in January 2009. In January 2009, Celldex also approached CuraGen expressing interest
in initiating new discussions. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
January 2009, CuraGen had due diligence meetings with both Party&nbsp;B and Party&nbsp;C. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
January&nbsp;20 and 21, 2009, the board of directors of CuraGen held a meeting during which it was agreed that CuraGen should hire an investment banking firm in order to assist in
evaluating strategic alternatives for CuraGen and that CuraGen should hire a consultant in order to assist in evaluating alternatives for the license or sale of CR011. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
January and February 2009, members of CuraGen management contacted and evaluated the potential services of various investment banking firms in order to assist in evaluating strategic
alternatives for CuraGen, and contacted and evaluated the potential services of a consultant for assistance in licensing or selling CR011. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
February&nbsp;11, 2009, the board of directors of CuraGen evaluated potential investment banking firms and consultants and approved the engagement of Piper
Jaffray&nbsp;&amp;&nbsp;Co. ("Piper Jaffray") to evaluate the company's strategic alternatives and the engagement of JSB Partners to assist in the licensing or sale of CR011. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
February&nbsp;13, 2009, CuraGen hired JSB Partners to assist in the license or sale of CR011. During the rest of February, JSB Partners prepared and distributed marketing material
related to the CR011 Program for distribution to potential licensors or acquirors of the CR011 Program. During February, March and April 2009, JSB contacted hundreds of potential licensors and
acquirors of the CR011 Program. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
February&nbsp;19, 2009, CuraGen hired Piper Jaffray to assist in identifying and evaluating strategic transactions for CuraGen, and CuraGen issued a press release announcing that
CuraGen was considering a broad range of strategic alternatives to enhance stockholder value, ranging from selling or licensing CR011, to acquiring additional assets or business lines, to selling the
company. The press release also indicated that CuraGen would retain an investment bank to assist in its strategic review, and had retained JSB Partners to identify potential acquirors of CR011. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Upon
review of the press release noted above, Party A indicated it was no longer interested in pursuing discussions with CuraGen. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
February&nbsp;20, 2009, Party C submitted a bid for CuraGen. The consideration to CuraGen stockholders would be a combination of shares of Party C with value equal to CuraGen's net
cash at closing and a contingent value right for CR011. CuraGen responded by letter dated February&nbsp;28, 2009 indicating that offers for the acquisition of CuraGen would be evaluated through
Piper Jaffray as part of CuraGen's overall review of strategic alternatives. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
February&nbsp;24, 2009, CuraGen's board of directors met and discussed the process for identifying and evaluating strategic transactions for the company as a whole and for CR011.
The Board was advised by Piper Jaffray as to the process for identifying bids for the sale of CuraGen as well as opportunities for CuraGen to acquire other assets and business, and was advised by JSB
Partners as to a process for identifying buyers or licensors for CR011. </FONT></P>

licensors of CR011. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
March 2009, Piper Jaffray prepared and distributed marketing materials related to CuraGen to potential strategic and financial bidders. During March and April 2009, Piper Jaffray
contacted 65&nbsp;companies. Piper Jaffray's marketing materials expressly stated that bids for the acquisition of
CuraGen must be submitted through Piper Jaffray rather than CuraGen. A total of 22&nbsp;preliminary bids were received by Piper Jaffray for CuraGen through this process. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
March&nbsp;6, 2009, Celldex's CEO and a representative of WBB Securities,&nbsp;LLC ("WBB Securities") (Celldex's financial advisor) participated in a conference call with Piper
Jaffray to discuss CuraGen's process for evaluating its options with respect to CuraGen as a whole and CR011. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
March&nbsp;18 and 19, 2009, the board of directors of CuraGen held a meeting during which JSB Partners reviewed with the board the process for identifying and evaluating buyers or
licensors for CR011 and Piper Jaffray reviewed progress with respect to bids for a sale of the entire company. The board then discussed other strategic alternatives for CuraGen, including the
liquidation and dissolution of the company and the continuation of the Company as a standalone entity focused on the development of CR011. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
March&nbsp;24, 2009, Celldex entered into another confidentiality agreement with CuraGen in connection with its receipt of marketing materials from Piper Jaffray. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Also
in March 2009, diligence was resumed with Party A, which had again indicated interest in an acquisition of CuraGen but did not offer any proposed terms for the acquisition. On

April&nbsp;15, 2009, a telephonic meeting of CuraGen's board of directors was held. Piper Jaffray presented and discussed the merits of the 22 preliminary bids received by Piper
Jaffray for CuraGen. After reviewing the 22 preliminary bids, CuraGen's board instructed management and Piper Jaffray to negotiate with Celldex, Party A, Party B, Party C and Party D. Criteria for
selection included but were not limited to the potential acquiror being a public company; the viability of the combined entity as a public company (based on the following factors, among others:
technology and business model, near term risks and value drivers, management and board and additional financing requirements); valuation expectations (taking into account, among other things, relative
ownership / premium to CuraGen stockholders and potential for flexibility regarding structure or valuation); and expected liquidity for CuraGen stockholders. CuraGen's board also considered that the
JSB process focused on CR011 had resulted in over 20 companies entering into confidentiality agreements and conducting diligence, but no bids for the asset. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;During
the remainder of April 2009, CuraGen management and Piper Jaffray held meetings with Celldex, Party D, and Party C and an update diligence call with Party A. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
April&nbsp;21, 2009, the board of directors of CuraGen held a meeting during which CuraGen's CEO provided an update regarding the JSB Partners process with respect to CR011 and
Piper Jaffray provided an update on the company sale process. The board discussed the five remaining bidders, Celldex, Party A, Party B, Party C and Party D, and the timelines and process over the
next two weeks in an attempt to improve the bids, narrow the list of bidders to a smaller number and begin to negotiate definitive agreements. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
April&nbsp;26, 2009, the board of directors of CuraGen met by teleconference. The board discussed progress in the Piper Jaffray process, and decided not to proceed further with
negotiations with Party D due to the board's determination that Party D's bid was inadequate compared to other bids. The board also discussed next steps with respect to the remaining bidders. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
April&nbsp;27, 2009, Party B withdrew its bid. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
April&nbsp;28, 2009, Party A submitted a revised bid that increased the prior bid's premium paid to net cash to reflect technology value. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
April&nbsp;29, 2009, Piper Jaffray informed Celldex that its bid was not adequate and invited Celldex to submit an updated non-binding indication of interest. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;1, 2009, Celldex submitted a revised bid that provided for the acquisition of CuraGen for consideration of up to $97,500,000 in Celldex shares, assuming that CuraGen had
net cash at the closing of the transaction of no less than $57,000,000. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Also
on May&nbsp;1, 2009, a telephonic meeting of CuraGen's board of directors was held at which Piper Jaffray reviewed revised bids from Celldex, Party A, Party C and Party D.
Celldex's revised bid of May&nbsp;1 increased its prior bid by approximately 14% and included a potential upward adjustment based on net cash at closing. Party A's revised bid of April&nbsp;28
increased its prior bid by approximately 15% and eliminated certain restrictive terms contained in its initial bid. Party C's revised bid of April&nbsp;28 increased its prior bid by approximately
12%. Party D's revised bid of May&nbsp;1 increased its prior bid by approximately 11% and made certain changes to the proposed structure of the transaction. CuraGen's board instructed management and
Piper Jaffray to continue to negotiate with Celldex and Party A. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;During
the week of May&nbsp;4, Piper Jaffray informed Party A that their current bid was not adequate and that if they were unable to increase their bid that negotiations with Party A
would be terminated. Party A did not increase their bid and negotiations with Party A were terminated. Also during the week of May&nbsp;4, representatives of Piper Jaffray contacted representatives
of Party C and Party D to inform them that CuraGen would not be continuing negotiations with them. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;13, 2009, CuraGen's board met by teleconference for an update on negotiations with Celldex and to review outstanding issues. Representatives of CuraGen management, Piper

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;13, 2009, Lowenstein sent a revised draft merger agreement to WilmerHale. The revised draft reflected, among other things, a dollar-for-dollar
downward adjustment in the purchase price in the event CuraGen's net cash at closing was below $57,000,000; further modifications to the calculation of net cash; one representative for CuraGen on the
combined company board; and a ceiling on Celldex shares to be issued under the merger agreement of 49.9% of the outstanding shares of Celldex common stock (on a fully diluted basis) following the
closing of the transaction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;13, 2009, after discussions with its legal and financial advisors, CuraGen proposed, and Celldex indicated such changes were acceptable, certain changes to the revised
draft merger agreement,
including the inclusion of proceeds from exercise of CuraGen in-the-money options in the computation of net cash at closing, certain other changes to the calculation of net
cash at closing and the elimination of the 49.9% ceiling on the number of Celldex shares that could be issued pursuant to the merger. </FONT></P>

May&nbsp;15, 2009, WilmerHale and Lowenstein held a conference call to review the revised draft merger agreement sent by Lowenstein on May&nbsp;13. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;18, 2009, representatives of WilmerHale, Lowenstein, Piper Jaffray, WBB Securities, Celldex management and CuraGen management met at Lowenstein's offices in Roseland, New
Jersey, to negotiate the merger agreement. Among the issues discussed was an adjustment to the purchase price to reflect CuraGen's revised estimate of net cash at closing, which was approximately
$54,500,000 assuming an August&nbsp;31, 2009 closing date; the pricing at which CuraGen's convertible debt could be repurchased by CuraGen during the period between the announcement of the Merger
and the closing of the Merger; and the definition of "in-the-money" options for purposes of calculation of net cash at closing, which was determined to be all options
outstanding under CuraGen's 2007 Stock Incentive Plan with an exercise price less than or equal to $1.67. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On

downward adjustment to the purchase price on a greater than dollar-for-dollar basis in the event that CuraGen did not deliver a specified amount of net cash at closing. The
representatives also discussed various mechanisms that would permit CuraGen's stockholders to obtain greater assurance of
value in the merger, including a floor on the number of shares of Celldex common stock issuable in the transaction to ensure that CuraGen stockholders would receive a specified minimum percentage of
the combined company in the event of a significant increase in Celldex's stock price. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Later
in the day on May&nbsp;20, 2009, Lowenstein indicated to WilmerHale that in order for Celldex to continue to incur the significant time and expense required for conducting its

May&nbsp;21, 2009, a telephonic meeting of the CuraGen board of directors was held. CuraGen's management, WilmerHale and Piper Jaffray reviewed the terms of the draft merger
agreement and the status of existing open issues, including Celldex's request for an exclusivity agreement. The board of directors authorized CuraGen management to enter into an exclusivity agreement
with Celldex in exchange for Celldex's agreement on several outstanding issues, including a dollar-for-dollar downward adjustment to the purchase price based upon CuraGen's net
cash at closing, and a floor and sufficiently high ceiling on the issuance of Celldex shares pursuant to the merger. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;22, 2009, CuraGen's CEO and Celldex's CEO spoke by phone and reached agreement on several outstanding issues, and accordingly both parties signed an exclusivity agreement
in a form negotiated by the parties providing for exclusivity through May&nbsp;29, 2009. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;22, 2009, the audit committee of Celldex's board of directors met and discussed financial and tax due diligence with Celldex's management and with PricewaterhouseCoopers
and authorized PricewaterhouseCoopers to perform additional tax analysis with respect to CuraGen's operations. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;23, 2009, WilmerHale circulated a revised draft merger agreement reflecting the comments of CuraGen, including a ceiling of 58% on the percentage of Celldex shares to be
issued pursuant to the merger as well as a floor of 32.2%, which lower threshold was based upon an analysis by Piper Jaffray, calculated in each case by reference to the fully diluted number of shares
of Celldex's common stock. The revised draft also reflected CuraGen's position on net cash at closing, which was that the purchase price would be $94,500,000 if CuraGen delivered $54,500,000 of net
cash at closing, would increase by $1.30 for each additional dollar of net cash at closing above $54,500,000, up to $57,000,000, and would decrease on a dollar-for-dollar basis
for each dollar below $54,500,000 in net cash at closing. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On May&nbsp;25, 2009, Lowenstein sent WilmerHale a memo reflecting Celldex's concerns with the May&nbsp;23 revised draft merger agreement. The memo indicated
that Celldex's position was that the purchase price should decrease on a dollar-for-dollar basis for each dollar of CuraGen net cash at closing below $54,500,000 until it
reached $54,000,000, and by $1.30 per for each dollar thereafter, and that the purchase price should increase by $1.30 for each additional dollar of cash at closing until the purchase price reached a
ceiling of $97,500,000, and on a dollar-for-dollar basis thereafter to a maximum purchase price of $100,000,000. The memo also indicated that Celldex did not agree to the 32.2%
floor on the issuance of Celldex stock pursuant to the merger or the method of calculating the 58% ceiling. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;26, 2009, the audit committee of Celldex's board of directors met with Celldex management and PricewaterhouseCoopers to discuss the results of additional due diligence
performed by PricewaterhouseCoopers. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;After
consultation with their respective legal and financial advisors, on May&nbsp;27, 2009, Celldex and CuraGen, together with their legal and financial advisors, held a conference
call during which they reached agreement on the purchase price, purchase price adjustments based upon net cash at closing, including the removal of the adjustment of $1.30 per each dollar shortfall
for net cash at closing of less than $54,000,000, and the inclusion in the merger agreement of a floor for the issuance of Celldex stock, which was set at 32.5%. The parties also agreed that the
ceiling and the floor on the number of
shares of Celldex common stock issuable in connection with the merger would be calculated on the basis of the number of shares of Celldex common stock outstanding immediately after the closing. </FONT></P>

May&nbsp;27, 2009, a telephonic meeting of CuraGen's board of directors was held. Management, WilmerHale and Piper Jaffray reviewed and discussed developments in the terms of the

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At
the effective time of the merger, Cottrell Merger Sub, a wholly-owned subsidiary of Celldex, will merge with and into CuraGen with CuraGen surviving the merger as a wholly-owned
subsidiary of Celldex. CuraGen stockholders will be entitled to receive shares of Celldex common stock in exchange for the shares of CuraGen stock they own in accordance with the terms of the merger
agreement, described in more detail below. Additionally, at the effective time of the merger, all options to purchase common stock then outstanding under the 2007 Stock Plan will be assumed by Celldex
and converted into options to purchase shares of Celldex common stock in accordance with the terms of the merger agreement. All options outstanding under the 1997 Stock Plan that are not exercised
prior to the effective time of the merger will terminate and be of no further force and effect upon the effective time of the merger. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
terms of the merger agreement provide for Celldex to issue shares of its common stock to CuraGen stockholders in exchange for all of the outstanding shares of CuraGen, other than
shares of CuraGen common stock owned by Celldex or held in CuraGen's treasury immediately prior to the effective time of the merger, which shares will be canceled without payment. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Although

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In evaluating the merger, the Celldex board of directors consulted with Celldex's management, Celldex's outside financial and legal
advisors and external experts in various aspects of its review of CuraGen's clinical development programs, CuraGen's portfolio of oncology-focused, fully-owned antibodies and the potential market
therefor, Celldex's and CuraGen's respective
intellectual property portfolios, CuraGen's current cash position and various other market analyses. These consultations included, among other things, discussions regarding: (a)&nbsp;continuing to
operate the Celldex business without entering into a merger transaction; (b)&nbsp;the business and strategic plans and financial position of the combined company and of an independent Celldex;
(c)&nbsp;the risks associated with executing the business and strategic plans of the combined company and of an independent Celldex; (d)&nbsp;the historical trading prices of Celldex's and
CuraGen's common stock; and (e)&nbsp;the terms and conditions of the merger agreement. In evaluating the merger, Celldex's board of directors considered both Celldex's short-term and
long-term interests, as well as those of its stockholders, consulted with management and legal and financial advisors and considered the following factors which in the aggregate it deemed

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Pursuant to an engagement letter, dated May&nbsp;26, 2009, Celldex retained BMC to render an opinion to the board of directors of

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
May&nbsp;28, 2009, the Celldex board of directors met to review the proposed merger. During this meeting, BMC reviewed with the Celldex board of directors certain financial
analyses, which are summarized below. Also, at this meeting, BMC delivered its oral opinion, subsequently confirmed in writing as of the same date, to the effect that and subject to the various
assumptions set forth in its written opinion, as of May&nbsp;28, 2009, that the Common Stock Exchange Ratio was fair, from a financial point of view, to Celldex. The amount of the Common Stock
Exchange Ratio was determined pursuant to negotiations between Celldex and CuraGen and not pursuant to recommendations of BMC. The full text of the written opinion of BMC dated May&nbsp;28, 2009, is
attached as Annex&nbsp;B and is incorporated by reference. Holders of Celldex common stock are urged to read the opinion in its entirety for the assumptions made, procedures followed, other matters
considered and limits of the review by BMC. The summary of the written opinion of BMC set forth herein is qualified in its entirety by reference to the full text of such opinion. </FONT></P>

has been reasonably prepared on a basis reflecting the best then currently available estimates and judgments, and that such information provides a reasonable basis upon which it could make
an analysis and form an opinion. The projections used by BMC were prepared by Celldex management and CuraGen management and are not to be interpreted as projections of future performance (or
"guidance") by Celldex or CuraGen. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;BMC
assumed that the transaction will be consummated in a manner that complies in all respects with the applicable provisions of the Securities Act of 1933, as amended, the Securities
Exchange Act of 1934, as amended, and all other applicable federal and state statutes, rules and regulations. BMC also assumed that obtaining all regulatory approvals and third party consents, if any,
required for the consummation of the acquisition would not have an adverse impact on Celldex, CuraGen or on the anticipated benefits of the acquisition. BMC further assumed that the acquisition of
CuraGen as described in the merger agreement would be consummated in a timely manner without waiver or modification of any of the material terms or conditions contained therein. In arriving at its
opinion, BMC did not conduct a physical inspection of CuraGen's properties or facilities and did not make or obtain any evaluation or appraisal of the assets or liabilities of CuraGen. In addition,
BMC did not attempt to confirm whether Celldex and CuraGen had good title to their respective assets. BMC's opinion set forth herein is necessarily based upon financial, market, economic and other
conditions and circumstances as they existed and were disclosed on, and were evaluated as of May&nbsp;28, 2009. Accordingly, although subsequent developments may affect its opinion, BMC has not
assumed any obligation to update, review or reaffirm its opinion. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
summary set forth below does not purport to be a complete description of all the analyses performed by BMC. The preparation of a fairness opinion involves various determinations as
to the most appropriate and relevant methods of financial analyses and the application of these methods to the particular circumstances and, therefore, such an opinion is not readily susceptible to
partial analysis or summary description. BMC did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and
relevance of each analysis and factor. Accordingly, notwithstanding the separate factors summarized above, BMC believes, and has advised the Celldex board of directors, that its analyses must be
considered as a whole and that selecting portions of its analyses and the factors considered by it, without considering all analyses and factors, could create an incomplete view of the process
underlying its opinion. In performing its analyses, BMC made numerous assumptions with respect to industry performance, business and economic conditions and other matters, many of which are beyond the
control of Celldex and CuraGen. These analyses performed by BMC are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than suggested by
such analyses. In addition, analyses relating to the value of businesses do not purport to be appraisals or to reflect the prices at which businesses or securities may actually be sold. Accordingly,
such analyses and estimates are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors. None of Celldex, CuraGen,
BMC or any other person assumes responsibility if future results are materially different from those projected. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
analyses performed were prepared solely as part of BMC's analysis of the fairness, from a financial point of view, of the Common Stock Exchange Ratio to Celldex pursuant to Celldex's
acquisition of CuraGen, and were provided to the Celldex board of directors in connection with the delivery of BMC's opinion. The opinion of BMC was just one of the many factors taken into account by
the Celldex board of directors in making its determination to approve the transaction, including those described elsewhere in this joint proxy statement/prospectus. </FONT></P>

merger agreement ("Purchase Price") to the extent that CuraGen fails to deliver to Celldex net cash and related assets of $54.5&nbsp;million at closing ("Net Cash"). The anticipated
$40&nbsp;million difference between the Purchase Price and the Net Cash, implies the value that is being ascribed to CuraGen's technology in the merger ("CuraGen Technology Value"). </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;BMC considered in its analysis that the Common Stock Exchange Ratio may range between 0.36x ("Maximum Exchange Ratio", which represents the maximum number of
shares of Celldex common stock issuable pursuant to the merger as a result of the collar on the exchange ratio) and 0.13x ("Minimum Exchange Ratio", which represents the minimum number of shares of
Celldex common stock issuable pursuant to the merger as a result of the collar on the exchange ratio). BMC noted that the Common Stock Exchange Ratio became more favorable to Celldex as it decreased. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;BMC
considered and analyzed the acquisition of CuraGen in two parts, the receipt of cash (deemed comparable to an equity offering) and an acquisition of CuraGen technology and other
non-cash assets. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I> Comparable Offering Analysis&#151;Celldex  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As part of its analysis, BMC selected and evaluated 26 biotech common stock equity offerings completed between August 2008 to present
that were deemed by BMC to be comparable to what Celldex would encounter if it were required to raise a similar amount of funding currently. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;BMC
noted that the average cost of capital (or effective discount) to the 26 issuing companies was: </FONT></P>

<UL>
<DL compact>
<DT style='font-family:times;margin-bottom:-11pt;'><FONT SIZE=2>&#149;</FONT></DT><DD style="font-family:times;"><FONT SIZE=2>42.7% Mean  </FONT> <FONT SIZE=2>
<BR><BR></FONT></DD><DT style='font-family:times;margin-bottom:-11pt;'><FONT SIZE=2>&#149;</FONT></DT><DD style="font-family:times;"><FONT SIZE=2>32.7% Median </FONT></DD></DL>
</UL>

<P style="font-family:times;"><FONT SIZE=2>Based
on the above, BMC estimated that Celldex would incur a 40.0% cost of capital to raise net cash of $54.5&nbsp;million in a common stock equity offering without warrants. A 40.0% cost of capital
applied against Celldex's 30-day volume weighted average common stock price ("30-Day VWAP") of $8.34/share as of May&nbsp;26, 2009, equaled $5.00/share. As such, in order for
Celldex to raise $58.0&nbsp;million of gross proceeds (net proceeds of $54.5&nbsp;million after 6% transaction costs), Celldex would be required to issue 11.6&nbsp;million shares, which
constitutes 42.3% of its outstanding shares of common stock post-issuance ("Comparable Equity Offering"). </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Comparably,
if the share price of Celldex common stock used in the exchange ratio were to be at or above the 30-Day VWAP (assuming net cash of $54.5&nbsp;million at
closing) and, as a result, the exchange ratio were to be 0.19x, then the number of shares issued at Closing would be 11.33&nbsp;million&#151;substantially equivalent to that required to be
issued in a Comparable Equity Offering. As such, BMC calculated that at a Common Stock Exchange Ratio of 0.19x (or below), all CuraGen Technology Value would be accretive and obtained without
substantial cost to Celldex. BMC determined that this was supportive of BMC's conclusion that the Common Stock Exchange Ratio is fair, from a financial point of view, to Celldex. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Alternatively
and pursuant to the merger agreement, BMC's analysis showed that (i)&nbsp;at the Maximum Exchange Ratio (0.36x), the worst case scenario for purposes of its opinion,
Celldex would issue to CuraGen approximately 21.8&nbsp;million shares in the merger (representing 58% of the shares of Celldex common stock outstanding immediately post-Closing); and
(ii)&nbsp;that the Celldex share price would need to be 47% below the 30-Day VWAP in order to arrive at the share price ($4.33) necessary to reach the Maximum Exchange Ratio. BMC
determined that this was supportive of BMC's conclusion that the Common Stock Exchange Ratio is fair, from a financial point of view, to Celldex. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>This
analysis supported BMC's determination that the Common Stock Exchange Ratio was fair, from a financial point of view, to Celldex because the CuraGen technology value implied by the anticipated

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;BMC observed that at the Maximum Exchange Ratio possible pursuant to the terms of the merger agreement, CuraGen's implied Technology
Value equaled $85.5&nbsp;million. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Across

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Based on the information and analyses set forth above, BMC delivered its written opinion to Celldex's Board of Directors, which stated
that, as of May&nbsp;28, 2009, based upon and
subject to the assumptions made, matters considered, and limitations on its review as set forth in the opinion, the Common Stock Exchange Ratio was fair, from a financial point of view, to Celldex. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;BMC
was selected by the Celldex board of directors to render an opinion to the Celldex board because BMC is a nationally recognized investment banking firm and because, as part of its
investment banking business, BMC is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, secondary
distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. BMC is providing financial services for Celldex for which it will receive customary
fees. In addition, in the ordinary course of its business, BMC and its affiliates may trade the equity securities of Celldex and CuraGen for their own account and for the accounts of their customers,
and, accordingly, may at any time hold a long or short position in such securities. BMC and its affiliates in the ordinary course of business have, from time to time, provided, and in the future may
continue to provide, commercial and investment banking services to Celldex, including serving as a financial advisor on potential acquisitions and as an underwriter or private placement agent for
equity offerings, and may in the future receive, fees for the rendering of such services. Pursuant to the BMC engagement letter, BMC will be entitled to receive a customary fee. Additionally, Celldex
has agreed to indemnify BMC against certain liabilities, including liabilities under the federal securities laws. The terms of the fee arrangement with BMC, which are customary in transactions of this
nature, were negotiated at arm's length between Celldex and BMC, and the Celldex board of directors was aware of and approved the arrangement. </FONT></P>

requested, to render an opinion to it as to the fairness, from a financial point of view, of the purchase price to be paid by Celldex in connection with the merger. On May&nbsp;28, 2009, the CuraGen
board of directors met to review the proposed merger. During this meeting, Piper Jaffray reviewed with the CuraGen board of directors certain financial analyses, which are summarized below. Also at
this meeting, Piper Jaffray delivered its oral fairness opinion to CuraGen's board of directors, which was subsequently confirmed in writing, to the effect that, as of May&nbsp;28, 2009, and based
upon and subject to the factors, assumptions made, matters considered, procedures followed and limitations on the scope of the review undertaken by Piper Jaffray set forth in its written opinion, the
purchase price specified in the merger agreement is fair, from a financial point of view, to the holders of CuraGen common stock, other than Celldex and its affiliates, if any. </FONT></P>

Jaffray calculated the implied equity value for CuraGen by determining the enterprise values of the selected public and private biopharmaceutical companies based on the acquisition
value for such transaction adjusted, where applicable, for cash, net of debt, based on publicly available information and then added the estimate of CuraGen's cash, net of debt, at the expected
closing date of the merger as estimated by CuraGen management. The purchase price of $94.5&nbsp;million is above the $90.7&nbsp;million minimum value implied by the transactions included in this
analysis. In incorporating this analysis into Piper Jaffray's fairness opinion, Piper Jaffray considered that cash, net of debt, is a substantial portion of the value of CuraGen in this transaction. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Piper Jaffray considered the estimate of CuraGen's net cash at close, based on management's estimate of August&nbsp;31, 2009 for the

$54.5&nbsp;million. The purchase price of $94.5&nbsp;million is above the estimated net cash at the expected closing date of the merger. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Piper Jaffray conducted an analysis of the estimated liquidation value of CuraGen assuming an effective date concurrent with CuraGen
management's estimate of August&nbsp;31, 2009 for the closing date of the merger. Piper Jaffray relied on the management of CuraGen for estimates of, among other items, the expected cash balance as
of the estimated effective date of the liquidation, current and future obligations, and the potential liquidation value of CuraGen's technology and other assets on a base case and upside case
scenario. This analysis yielded a range of implied values for CuraGen of between $54.1&nbsp;million and $65.1&nbsp;million. The purchase price of $94.5&nbsp;million is above the estimated

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Although the summary set forth above does not purport to be a complete description of the analyses performed by Piper Jaffray, the
material analyses performed by Piper Jaffray in rendering its opinion have been summarized above. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to
partial analysis or summary description. Piper Jaffray believes that its analyses and the summary set forth above must be considered as a whole and that selecting portions of its analyses or of the
summary, without considering the analyses as a whole or all of the factors included in its analyses, would create an incomplete, misleading and/or inaccurate view of the processes underlying the
analyses set forth in the Piper Jaffray opinion. In arriving at its opinion, Piper Jaffray considered the results of all of its analyses and did not attribute any particular weight to any factor or
analysis considered by it, assign any relative weights to the factors or analyses or make any conclusion as to how the results of any given analysis, taken alone, supported its opinion. Instead Piper
Jaffray made its determination as to the fairness on the basis of its experience and financial judgment after considering the results of all of its analyses. The fact that any specific analysis has
been referred to in the summary above is not meant to indicate that this analysis was given greater weight than any other analysis. No company or transaction used in the above analyses as a comparison
is directly comparable to CuraGen, Celldex or the proposed merger. Accordingly, an analysis of the results of such a comparison is not purely mathematical, but instead involves complex considerations
and judgments concerning differences in historical and projected financial and operating characteristics of the selected companies and target companies in the selected transactions and other factors
that could affect the public trading value of the selected companies and target companies in the selected transactions. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
analyses were prepared solely for purposes of Piper Jaffray providing its opinion to the CuraGen board of directors that the purchase price set forth in the merger agreement to be
paid by Celldex was fair, from a financial point of view, to the holders of CuraGen common stock as of the date of the opinion. These analyses do not purport to be appraisals or to reflect the prices
at which CuraGen might actually be sold or the prices at which any securities may trade at the present time or at any time in the future. In performing its analyses, Piper Jaffray made numerous
assumptions with respect to CuraGen, Celldex, the proposed merger, industry performance, general business, economic, market and financial conditions and other matters. The analyses performed by Piper
Jaffray such as the net cash analysis and liquidation analysis discussed above are based upon forecasts by CuraGen management of future results, which are not necessarily indicative of actual values
or predictive of actual future results or values and may be significantly more or less favorable than suggested by these analyses. Additionally, analyses relating to the value of businesses or
securities of CuraGen or Celldex are not appraisals. These analyses are inherently subject to substantial uncertainty, being based upon </FONT></P>

Jaffray relied upon and assumed the accuracy, completeness and fairness of the financial, accounting and other information publicly available, furnished to it by CuraGen or
otherwise made available to it, and did not assume the liability or responsibility to independently verify this information. CuraGen has advised Piper Jaffray that it does not publicly disclose
internal financial information of the type provided to Piper Jaffray and used in the net cash analysis and liquidation analysis discussed above and that such information was prepared for financial
planning purposes and not with the expectation of public disclosure. Piper Jaffray also assumed, in reliance upon the assurances of the management of CuraGen and Celldex, that the information provided
to Piper Jaffray by CuraGen and Celldex was prepared on a reasonable basis in accordance with industry practice and, with respect to any financial forecasts, projections and other estimates and other
business outlook information, reflected the best currently available estimates and judgments of the management of CuraGen and Celldex as of the date of the opinion, is based on reasonable assumptions,
and that there is not, and the management of CuraGen and Celldex, was not aware of, any information or facts that would make the information provided to Piper Jaffray incomplete or misleading. Piper
Jaffray expresses no opinion as to any such financial forecasts, projections and other estimates and other business outlook information or the assumptions on which they are based. Piper Jaffray
relied, with CuraGen's consent, on advice of the outside counsel and the independent accountants to CuraGen, and on the assumptions of the management of CuraGen, as to all accounting, legal, tax and
financial reporting matters with respect to CuraGen, Celldex, the merger and the merger agreement. Without limiting the generality of the foregoing, Piper Jaffray assumed that CuraGen and Celldex were
not parties to any material pending transactions, including any external financing, recapitalization, acquisition or merger, divestiture or spinoff, other than the proposed merger, and did not
consider any other transactions in its analysis. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Piper
Jaffray assumed that the executed merger agreement would be in all material respects identical to the last drafts reviewed by it. Piper Jaffray assumed that the merger would be
completed on the terms set forth in the draft merger agreement dated May&nbsp;28, 2009 and all other related documents and instruments that are referred to therein, without amendments and with full
accuracy of the representations and warranties therein, and full and timely satisfaction of all covenants, agreements and conditions without any waiver. Piper Jaffray assumed that the potential
adjustment to the purchase price based on the amount of CuraGen cash at closing and the limitation on the amount of Celldex common stock to be issued as consideration for the merger shall not result
in any adjustment to the purchase price that is material to the analysis or opinion of Piper Jaffray. Without limiting the foregoing, Piper Jaffray assumed that the merger will qualify as a
tax-free reorganization pursuant to the Internal Revenue Code of 1986, as amended. In addition, Piper Jaffray assumed that all necessary regulatory approvals and consents required for the
merger will be obtained in a manner that will not result in the disposition of any material portion of the assets of CuraGen or Celldex, or otherwise adversely affect CuraGen or Celldex, and will not
affect the terms of the merger. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Piper
Jaffray did not assume responsibility for performing, and did not perform, any appraisals or valuations of specific assets or liabilities, either fixed, contingent or other, of
CuraGen or Celldex and was not furnished with any appraisals or valuations. Piper Jaffray expresses no opinion regarding the liquidation value of any entity. Piper Jaffray did not undertake any
independent analysis of any outstanding, pending or threatened litigation, regulatory action, possible unasserted claims or other contingent liabilities to which CuraGen, Celldex or any of CuraGen's
or Celldex's respective affiliates is a party or may be subject. At the direction of the CuraGen board of directors, and with its consent, Piper Jaffray's opinion made no assumption concerning, and
therefore did not consider, the potential effects of litigation, claims, investigations, or possible assertions of claims, or the outcomes or damages arising out of any such matters. </FONT></P>

relative to any alternative transaction or business strategy that may be available to CuraGen, (C)&nbsp;the structure of the merger, (D)&nbsp;Celldex's ability to issue shares of Celldex common
stock sufficient to fund the purchase price, or (E)&nbsp;any other terms contemplated by the merger agreement or the fairness of the merger to any other class of securities, creditor or other
constituency of CuraGen. Furthermore, Piper Jaffray expresses no opinion with respect to the amount or nature of any compensation to any officer, director or employee of any party to the proposed
transaction, or any class of such persons, relative to the consideration to be paid by Celldex in the proposed transaction or with respect to the fairness of any such compensation, including whether
such payments are reasonable in the context of the merger. </FONT></P>

Jaffray's opinion was provided to the CuraGen board of directors in connection with its consideration of the merger and is not intended to be and does not constitute a
recommendation to any stockholder of CuraGen as to how such stockholder should act or vote with respect to the merger or any other matter. As described above, Piper Jaffray's opinion was one of many
factors taken into consideration by the CuraGen board of directors in making its determination to approve the merger. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Prior
to approving the Celldex offer, CuraGen's board of directors engaged Piper Jaffray to assist CuraGen in reviewing, analyzing and evaluating strategic alternatives for CuraGen.
Piper Jaffray has, in the past, also provided financial advisory and financing services to CuraGen and/or its affiliates, for which Piper Jaffray did not receive compensation. Piper Jaffray may
continue to provide similar services, and may receive customary fees for the rendering of such services, in the future. Piper Jaffray may also, in the future, provide investment banking and financial
advisory services to CuraGen, Celldex or entities that are affiliated with CuraGen or Celldex, for which it would expect to receive compensation. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
addition, in the ordinary course of its business, Piper Jaffray and its affiliates may actively trade securities of CuraGen and Celldex for their own account or the account of their
customers and, accordingly, may at any time hold a long or short position in such securities. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The merger will be accounted for by applying the acquisition method in accordance with Statement of Financial Accounting Standards
("SFAS") No.&nbsp;141(R), Business Combinations (Revised) ("SFAS&nbsp;141(R)") with CuraGen considered the acquiree and Celldex the acquirer for accounting and financial reporting purposes.
CuraGen's assets, liabilities and other items will be adjusted to their estimated fair value on the closing date of the merger and combined with the historical book values of the assets and
liabilities of Celldex. The difference between the estimated fair value of CuraGen's assets, liabilities and other items (adjusted as discussed above) and the purchase price will be recorded as
goodwill on the financial statements of Celldex. The financial statements of Celldex issued after the merger will reflect the estimated fair values of CuraGen's assets, liabilities and other items
(adjusted as discussed above) and will not be restated retroactively to reflect the historical financial position or results of operations of CuraGen. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The consummation of the merger is conditioned on, among other things, the receipt by each of CuraGen and Celldex of tax opinions from
Wilmer Cutler Pickering Hale and Dorr&nbsp;LLP and Lowenstein Sandler PC, respectively, that for U.S. federal income tax purposes the merger will be treated as a reorganization within the meaning of
Section&nbsp;368(a) of the Code. These opinions will be based on certain assumptions and on representation letters to be provided by CuraGen and Celldex at the time of consummation. Neither of these
tax opinions will be binding on the Internal Revenue Service. Neither Celldex nor CuraGen intends to request any ruling from the Internal Revenue Service as to the U.S. federal income tax consequences
of the merger. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
the merger qualifies for U.S. federal income tax purposes as a reorganization within the meaning of Section&nbsp;368(a) of the Code, the material U.S. federal income tax

the merger is not completed pursuant to the terms of the merger agreement or if the assumptions or representations on which the tax opinions will be based are incorrect in certain
material respects, the tax consequences of the merger could differ materially from those set forth above. In particular, in such event, the exchange by U.S. holders of their CuraGen common stock for
Celldex common stock pursuant to the merger could be taxable depending on the particular facts surrounding the merger, some of which may not be known until completion of the merger. If the merger is
taxable, then a U.S. holder generally would recognize gain or loss on the exchange of CuraGen common stock for Celldex common stock measured by the difference between the fair market value of the
Celldex common stock (together with any cash received in lieu of a fractional interest in Celldex common stock) received by such U.S. holder and such U.S. holder's basis in the CuraGen common stock
surrendered. </FONT></P>

share pursuant to the merger and then
as having exchanged the fractional share for cash in a redemption by Celldex. As a result, a U.S. holder generally will recognize gain or loss equal to the difference between the amount of cash
received and the basis in his or her fractional share interest as set forth above. This gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if,
as of the effective date of the merger, the holding period for such fractional share is greater than one year. The deductibility of capital losses is subject to limitations. </FONT></P>

a rate of 28%), unless the holder provides proof of an applicable exemption or furnishes its taxpayer identification number, and otherwise complies with all applicable requirements of the backup
withholding rules. Any amount withheld from payments to a holder under the backup withholding rules is not an additional tax and will be allowed as a refund or credit against the holder's U.S. federal
income tax liability, provided the required information is timely furnished to the Internal Revenue Service. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A U.S. holder who receives shares of Celldex common stock as a result of the merger will be required to retain records pertaining to
the merger. Each U.S. holder who is required to file&nbsp;a United States federal income tax return and who is a "significant holder" that receives Celldex common stock generally will be required to
file&nbsp;a statement with such holder's United States federal income tax return setting forth the names and employer identification numbers of all of the parties to the merger, the date of the
merger, and the fair market value, determined immediately before the exchange, of all of the CuraGen common stock held by such significant holder that is transferred in the merger and such significant
holder's basis, determined immediately before the exchange, in the CuraGen common stock. A "significant holder" is a U.S. holder who immediately before the merger owned at least 5% (by vote or value)

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Following the merger, any or all of CuraGen's employees may continue to be employed by the surviving corporation. The merger agreement
requires Celldex to notify CuraGen of the identity of the employees to whom it intends to make offers of employment no less than 40 business days prior to closing. However, no employment terms were
negotiated in advance of the signing of the merger agreement, and the merger is not conditioned on any such arrangements. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I> D&amp;O Liability Insurance and Indemnification  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under the merger agreement, Celldex has agreed that for a period of six years after the completion of the merger, Celldex and the
surviving corporation will maintain CuraGen's current directors' and officers' liability insurance policies (or comparable replacement coverage) with respect to claims arising from facts or events
that existed or occurred prior to the effective time of the merger, subject to certain limitations. In addition, for six years, Celldex and the surviving corporation will indemnify CuraGen's directors
and executive officers to the fullest extent permitted under the General Corporation Law of the State of Delaware (which we sometimes refer to in this joint proxy statement/prospectus as the
"DGCL"), and Celldex and the surviving corporation will cause the surviving corporation to maintain indemnification provisions in the surviving corporation's organizational documents
which are not less favorable than in CuraGen's current organizational documents. See "The Merger Agreement&#151;Directors' and Officers' Indemnification and Liability Insurance commencing on
page&nbsp;89." </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I> Current Employment and Severance Arrangements  </I></FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;CuraGen has entered into an employment agreement with each of its executive officers. Under the terms of these agreements, the merger
will likely constitute a change in control of CuraGen. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Pursuant
to the employment agreements, if the executive officer is terminated for reasons other than cause (as defined in the agreement), disability or death within twelve months of a
change in control, or if the executive officer terminates his employment for good reason (as defined in the agreement) within twelve months of a change in control, the executive officer will be
entitled to receive salary continuation for twenty-four (24)&nbsp;months, an amount equal to two (2)&nbsp;times his target annual bonus under CuraGen's Executive Incentive Plan, paid
in an immediate lump sum, and insurance continuation under COBRA for any employee health and welfare benefit in which the executive officer was a participant prior to termination, with the applicable
premiums being paid by CuraGen at the same percentage as immediately prior to termination, for up to twenty-four (24)&nbsp;months following termination of his or her employment, provided
that, if COBRA continuation coverage is otherwise earlier terminated under applicable law, then, in lieu of coverage, the surviving corporation will pay its share of the monthly employer premium in
effect prior to the termination of COBRA continuation coverage directly to the executive officer each month for the remainder of the relevant period. The timing of severance payments made under the
employment agreements are subject to certain restrictions specified in the agreements for purposes of compliance with Section&nbsp;409A of the Code. In the event it is determined that any payment
under the agreements to an executive officer in the event of a change in control would be subject to Section&nbsp;280G of the Code or the excise tax imposed by Section&nbsp;4999 of the Code, such
executive officer will receive the greater of (i)&nbsp;the total value of the payments to be paid to the executive officer upon a change of control, reduced to an amount that will </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Prior to the closing of the merger, the compensation committee of CuraGen's board of directors may, in its sole discretion, decide to
grant cash bonuses to executive officers and other employees under the CuraGen Executive Incentive Plan for 2009 in a maximum aggregate amount of $1,156,833 if it determines that certain corporate
goals have been met. These broad goals include implementing strategic initiatives and transactions, maintaining financial and operational performance and advancing CuraGen's pipeline, and are similar
to CuraGen's corporate goals for 2008. Under the Executive Incentive Plan and his respective employment agreement, each CuraGen executive may receive from zero to two times his target annual cash
bonus set forth above, with the amount of the bonus to be determined in the sole discretion of the compensation committee. Any such bonuses would be in addition to amounts described above that the
executive officers may be entitled to under their employment agreements. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2><I> Merger Consideration  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;CuraGen's executive officers and directors will receive the same merger consideration per share as other CuraGen stockholders for each
share of CuraGen common stock that they hold. See "Security Ownership of Certain Beneficial Owners and Management of CuraGen" commencing on page&nbsp;100 for a summary of the shares of CuraGen
common stock held by CuraGen directors and executive officers. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under the terms of the executive employment agreements, the merger will likely constitute a change of control of CuraGen and all
unvested restricted common stock will become fully vested at the effective time and be treated like other shares of CuraGen common stock for purposes of the merger. As of May&nbsp;31, 2009, the
number of shares of restricted common stock held by the executive officers was as follows: </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;CuraGen's directors and executive officers hold options to purchase CuraGen's common stock. All options granted under CuraGen's 2007
Stock Plan will be assumed by Celldex and, following the merger, will represent options to purchase the number of shares of Celldex common stock equal to the merger consideration that would have been
received for the shares of CuraGen common stock issuable upon exercise of such options, with the exercise price proportionally adjusted. All options granted under CuraGen's 1997 Stock Plan will become
fully vested for a specified period prior to the effective time of the merger, and if not exercised, will be cancelled immediately prior to the merger. All options held by CuraGen
non-employee directors are currently vested, and all options held by CuraGen's executive officers, to the extent not currently vested, will vest in fully immediately prior to the effective
time of the merger in accordance with the terms of the executive employment agreements. As of the record date, options to purchase

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Following the announcement of the proposed acquisition by Celldex of CuraGen, a putative class action complaint, </FONT> <FONT SIZE=2><I>Margaret Capps v. Timothy Shannon, et
al.</I></FONT><FONT SIZE=2>, was filed in the
Connecticut Superior Court, Judicial District of New Haven, on June&nbsp;9, 2009. A second putative class action complaint, </FONT><FONT SIZE=2><I>Cheryl Smith v. CuraGen Corporation, et
al.</I></FONT><FONT SIZE=2>, was filed in the Court of Chancery of the State of Delaware on June&nbsp;15, 2009. Both lawsuits purport to be brought on behalf of all public stockholders of CuraGen,
and name CuraGen, all of its directors, Celldex, and Cottrell Merger Sub as defendants. The complaints allege, among other things, that the merger consideration to be paid to CuraGen stockholders in
the merger is unfair and undervalues CuraGen. In addition, the complaints allege that CuraGen's directors violated their fiduciary duties by, among other things, failing to maximize stockholder value
and failing to engage in a fair sale process. The complaints also allege that CuraGen and Celldex aided and abetted the alleged breach of fiduciary duties by CuraGen's directors. The complaints seek,
among other relief, an injunction preventing completion of the merger or, if the merger is consummated, rescission of the merger. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;These
lawsuits are in their preliminary stages. Celldex, Cottrell Merger Sub, CuraGen and the individual defendants filed answers to the putative class action complaint, </FONT> <FONT SIZE=2><I>Cheryl Smith v. CuraGen Corporation, et. al.</I></FONT><FONT
SIZE=2>, in the Chancery Court of the State of Delaware on June&nbsp;22, 2009. Both Celldex and CuraGen believe
the lawsuits are without merit and intend to defend vigorously against them. Additional lawsuits pertaining to the merger could be filed in the future. </FONT></P>

that contract between the parties and are subject to qualifications and limitations agreed by the parties in connection with negotiating the terms of that contract. The representations and warranties
have been qualified by certain disclosures that were made to the other party in connection with the negotiation of the merger agreement, which disclosures are not reflected in the merger agreement. In

<BR></FONT><FONT SIZE=2><B>  The Exchange Ratio    <BR>    </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The terms of the merger agreement provide for Celldex to issue shares of its common stock to CuraGen stockholders in exchange for all
of the outstanding shares of CuraGen, other than shares of CuraGen common stock owned directly or indirectly by Celldex or held in CuraGen's treasury immediately prior to the effective time of the
merger, which shares will be canceled without payment. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Although
the applicable exchange ratio cannot be definitively calculated until the closing, we currently estimate that the number of Celldex shares issuable in exchange for one CuraGen
share (also known as the "exchange ratio") will be [&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;]. This estimate assumes that the price of Celldex
common stock used in determining the exchange ratio is
[$&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;] (the most recent closing sales price before the mailing of this joint proxy statement/prospectus) and that CuraGen will have Cash at Closing (as
defined
below) equal to $54,500,000. The actual exchange ratio, however, may differ from this estimate. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under
the merger agreement, the exchange ratio will be determined by the following formula: </FONT></P>

<P ALIGN="CENTER" style="font-family:times;"><FONT SIZE=2>CuraGen
Common Stock Per Share value (as defined below)<BR>

<!-- COMMAND=ADD_LINERULETXT,NOSHADE  COLOR="#000000" SIZE="1.0PT" WIDTH="58%" ALIGN="CENTER" -->

<BR>
Celldex Common Stock Per Share Value (as defined below) </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>However,
if the formula results in an exchange ratio that would require Celldex to issue a number of shares of common stock (including shares issued upon exercise of CuraGen in-the-money options
assumed by Celldex in the merger) that would exceed 58% of the sum of the total number of shares of Celldex common stock outstanding immediately after the effective time of the merger (which number
includes the shares of CuraGen common stock outstanding immediately prior to the effective time of the merger that are converted into shares of Celldex common stock in the merger)
<U>plus</U> the maximum number of shares of Celldex common stock issuable upon exercise of CuraGen in-the-money options assumed by Celldex in the merger, the exchange ratio will
automatically be reduced so that Celldex will be required to issue a number of shares of common stock equal to 58% of such number of shares. Similarly, if the formula results in an exchange ratio that
would require Celldex to issue a number of shares of common stock (including shares issued upon exercise of CuraGen in-the-money options assumed by Celldex in the merger) that is less than 32.5% of
the sum of the total number of shares of Celldex common stock outstanding immediately after the effective time of the merger (which number includes the shares of CuraGen common stock outstanding
immediately prior to the effective time of the merger that are converted into shares of Celldex common stock in the merger) <U>plus</U> the maximum number of shares of Celldex
common stock issuable upon exercise of CuraGen in-the-money options assumed by Celldex in the merger, the exchange ratio will automatically be increased so that Celldex will be required to issue a
number of shares of Celldex common stock equal to 32.5% of such number of shares. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;After
the effective time of the merger, each of CuraGen's outstanding stock certificates or book-entry shares representing shares of CuraGen common stock converted in the
merger will represent only the right to receive the number of shares of Celldex common stock determined in accordance with the formula shown above without any interest. The consideration paid upon
surrender of each certificate or book-entry share will be paid in full satisfaction of all rights pertaining to the shares of CuraGen's common stock represented by that certificate or
book-entry share. </FONT></P>

persons to act for such stockholder by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. A proxy shall be
irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power. A stockholder may revoke any proxy which
is not irrevocable by attending the meeting and voting in person or by delivering to the Secretary of the corporation a revocation of the proxy or a new proxy bearing a later date. Voting at meetings
of stockholders need not be by written ballot. At all meetings of stockholders for the election of directors at which a quorum is present a plurality of the votes cast shall be sufficient to elect.
All other elections and questions presented to the stockholders at a meeting at which a quorum is present shall, unless otherwise provided by the certificate of incorporation, these bylaws, the rules
or regulations of any stock exchange applicable to the corporation, or applicable law or pursuant to any regulation applicable to the corporation or its securities, be decided by the affirmative vote

entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the
purpose of any other lawful action, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board
of Directors, and which record date: (1)&nbsp;in the case of determination of stockholders entitled to vote at any meeting of stockholders or adjournment thereof, shall, unless otherwise required by

prior to such other action. If no record date is fixed: (1)&nbsp;the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of
business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held; (2)&nbsp;the
record date for determining stockholders entitled to express consent to corporate action in writing without a meeting, when no prior action of the Board of Directors is required by law, shall be the
first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the corporation in accordance with applicable law, or, if prior action by the Board
of Directors is required by law, shall be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action; and (3)&nbsp;the record date for
determining stockholders for any other purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto. A determination of stockholders of
record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the
adjourned meeting. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>Dear
Sirs: </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
understand that Celldex Therapeutics,&nbsp;Inc., a Delaware corporation ("Celldex"), intends to purchase Curagen Corporation ("Curagen"), a Delaware company, listed on the Nasdaq
Global Market, pursuant to a merger (the "Merger") whereby Curagen would become a wholly-owned subsidiary of Celldex. The Merger will be effected pursuant to an Agreement and Plan of Merger between
Celldex, Curagen and Celldex's newly formed merger subsidiary, a draft copy of which has been provided to us on May&nbsp;27, 2009 (the "Merger Agreement"). The Merger Agreement provides, among other
things, for the merger (the "Proposed Transaction") of Curagen with and into a subsidiary of Celldex. The terms of the Proposed Transaction are set forth in more detail in the Merger Agreement. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;You
have requested our opinion, as investment bankers, as to the fairness from a financial point of view, of the Common Stock Exchange Ratio (as defined in the Merger Agreement) to
Celldex. Our opinion addresses only the fairness, from a financial point of view, of the Common Stock Exchange Ratio, and we do not express any views on any other terms of the Proposed Transaction.
Specifically, we have not been requested to opine as to, and our opinion does not in any manner address, the relative merits of the Proposed Transaction as compared to any alternative business
strategy that might exist for Celldex. </FONT></P>

arriving at our opinion, we have assumed and relied upon the accuracy and completeness of the financial and other information used by us and we have not independently verified (nor
have we assumed any responsibility for the independent verification of) any such information, and we have further relied upon the assurances of Celldex and Curagen that they are not aware of any facts
or circumstances that would make such information inaccurate or misleading. We have further assumed that the transactions described in the Proposal will be consummated in a timely manner without
waiver or modification of any of the material terms or conditions contained therein. With respect to the projected financial information, we have assumed that such projected financial information has
been prepared in good faith and on bases and assumptions reflecting the best currently available judgments and estimates of Celldex's management as to the expected future results of operations and
financial condition. We express no opinion with respect to such projected financial information or the assumptions upon which it is based. We have not reviewed any of the books and records of Celldex
or made any independent valuation or appraisal of the assets or liabilities of Celldex. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
rendering our opinion, we have, with your consent, made the following assumptions: (i)&nbsp;that each of Celldex and Curagen will comply with all material terms of the Agreement;
(ii)&nbsp;that the Proposed Transaction will be consummated in accordance with the terms of the Merger Agreement without waiver, modification or amendment; (iii)&nbsp;that the final executed form
of the Merger Agreement will not differ in any material respect from the draft of the Merger Agreement reviewed by us; and (iv)&nbsp;that all consents and approvals necessary for the consummation of
the Proposed Transaction will be obtained without any adverse effect on the Proposed Transaction. We have also assumed that the representations and warranties made by Celldex and Curagen in the Merger
Agreement will be true and correct in all respects material to our analysis. We are not legal, regulatory or tax experts and have relied on the assessments made by advisors to Curagen with respect to
such issues. </FONT></P>

be advised that, during the two years preceding the date of this letter, neither we nor our affiliates have had any other significant financial advisory or other significant commercial or investment

Stock</I></FONT><FONT SIZE=2>"), of CuraGen Corporation (the "</FONT><FONT SIZE=2><I>Company</I></FONT><FONT SIZE=2>"), of the Purchase Price (as defined below) pursuant to a draft of the Agreement
and Plan of Merger, dated as of May&nbsp;28, 2009 (the "</FONT><FONT SIZE=2><I>Agreement</I></FONT><FONT SIZE=2>"), to be entered into among the Company, Celldex Therapeutics,&nbsp;Inc. (the
"</FONT><FONT SIZE=2><I>Acquiror</I></FONT><FONT SIZE=2>") and Cottrell Merger Sub&nbsp;Inc. ("</FONT><FONT SIZE=2><I>Merger Sub</I></FONT><FONT SIZE=2>"), a newly formed wholly-owned subsidiary
of the Acquiror. The Agreement provides for, among other things, the merger (the "</FONT><FONT SIZE=2><I>Merger</I></FONT><FONT SIZE=2>") of the Merger Sub with and into the Company, pursuant to
which each outstanding share of Company Common Stock, other than shares of Company Common Stock held in treasury or owned by the Acquiror, will be converted into the right to receive shares of common
stock, par value $0.001 per share, of the Acquiror (the "</FONT><FONT SIZE=2><I>Acquiror Shares</I></FONT><FONT SIZE=2>"). The Acquiror Shares issued as consideration for the Merger shall be deemed
to have a value equal to the volume weighted average of the closing prices of the Acquiror Shares on The Nasdaq Stock Market on fifteen randomly selected days during the period of thirty trading days
ending on the date that is two trading days prior to the effective time of the Merger. The "</FONT><FONT SIZE=2><I>Purchase Price</I></FONT><FONT SIZE=2>" shall equal $94,500,000 in the aggregate. We
understand that the Purchase Price will be subject to adjustment based on and to the extent that the amount of the Company's Cash at Closing Amount (as defined in the Agreement) is more or less than
$54,500,000, as set forth in the Agreement; </FONT><FONT SIZE=2><I>provided</I></FONT><FONT SIZE=2>, that the Purchase Price shall not exceed $100,000,000 (the "</FONT><FONT SIZE=2><I>Net Cash
Adjustment</I></FONT><FONT SIZE=2>"). We also understand that the Agreement contains provisions providing for a minimum and maximum amount of Acquiror Shares that may be issued in connection with the
Merger (the "</FONT><FONT SIZE=2><I>Acquiror Share Limitation</I></FONT><FONT SIZE=2>"). The terms and conditions of the Merger are more fully set forth in the Agreement. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In

certain information, including financial forecasts, relating to the business, earnings, cash flow, assets, liabilities and prospects of the Company and the Acquiror that were publicly available, as

concerning the matters described in clauses&nbsp;(ii) and (iii)&nbsp;above, as well as their respective businesses and prospects before and after giving effect to the Merger; (v)&nbsp;reviewed
the current and historical reported prices and trading activity of Company Common Stock and the Acquiror Shares and similar information for certain other companies deemed by us to be comparable to the
Company; (vi)&nbsp;compared the financial performance of the Company and the Acquiror with that of certain other publicly-traded companies that we deemed relevant; and (vii)&nbsp;reviewed the

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
have relied upon and assumed, without assuming liability or responsibility for independent verification, the accuracy and completeness of all information that was publicly available
or was furnished, or otherwise made available, to us or discussed with or reviewed by us. We have further relied upon the assurances of the management of the Company and the Acquiror that the
financial information provided has been prepared on a reasonable basis in accordance with industry practice, and that they are not aware of any information or facts that would make any information
provided to us incomplete or misleading. Without limiting the generality of the foregoing, for the purpose of this opinion, we have assumed that with respect to financial forecasts, estimates and
other forward-looking information reviewed by us, that such information has been reasonably prepared based on assumptions reflecting the best currently available estimates and judgments of the
management of the Company and the Acquiror as to the expected future results of operations and financial condition of the Company and the Acquiror, respectively, to which such financial forecasts,
estimates and other forward-looking information relate. We express no opinion as to any such financial forecasts, estimates or forward-looking information or the assumptions on which they were based.
We have further assumed that the Merger will qualify as a tax-free reorganization for United States federal income tax purposes. We have relied, with your consent, on advice of the outside
counsel and the independent accountants to the Company, and on the assumptions of the management of the Company, as to all accounting, legal, tax and financial reporting matters with respect to the
Company, the Acquiror and the Agreement. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
arriving at our opinion, we have assumed that the executed Agreement will be in all material respects identical to the last draft reviewed by us. We have relied upon and assumed,
without independent verification, that (i)&nbsp;the representations and warranties of all parties to the Agreement and all other related documents and instruments that are referred to therein are
true and correct, (ii)&nbsp;each party to such agreements will fully and timely perform all of the covenants and agreements required to be performed by such party, (iii)&nbsp;the Merger will be
consummated pursuant to the terms of the Agreement without amendments thereto (iv)&nbsp;all conditions to the consummation of the Merger will be satisfied without waiver by any party of any
conditions or obligations thereunder (v)&nbsp;that the Acquiror Share Limitation will not result in any adjustment that is material to our analysis, and (vi)&nbsp;that the Net Cash Adjustment will
not result in any adjustment to the Purchase Price that is material to our analysis. Additionally, we have assumed that all the necessary regulatory approvals and consents required for the Merger will
be obtained in a manner that will not adversely affect the Company, the Acquiror or the contemplated benefits of the Merger. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
arriving at our opinion, we have not performed any appraisals or valuations of any specific assets or liabilities (fixed, contingent or other) of the Company or the Acquiror, and have
not been furnished or provided with any such appraisals or valuations, nor have we evaluated the solvency of the Company or the Acquiror under any state or federal law relating to bankruptcy,
insolvency or similar matters. The analyses performed by us in connection with this opinion were going concern analyses. We express no opinion regarding the liquidation value of the Company, the
Acquiror or any other entity. Without limiting the generality of the foregoing, we have undertaken no independent analysis of any pending or threatened litigation, regulatory action, possible
unasserted claims or other contingent liabilities, to which the Company, the Acquiror or any of their affiliates is a party or may be subject, and at the direction of the Company and with its consent,
our opinion makes no assumption concerning, and therefore does not consider, the possible assertion of claims, outcomes or damages arising out of any such matters. We have also assumed that neither
the Company nor the Acquiror is party to any material pending transaction, including without limitation any financing, recapitalization, acquisition or merger, divestiture or spin-off,
other than the Merger. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This
opinion is necessarily based upon the information available to us and facts and circumstances as they exist and are subject to evaluation on the date hereof; events occurring after
the date hereof </FONT></P>

materially affect the assumptions used in preparing this opinion. We are not expressing any opinion herein as to the price at which shares of Company Common Stock or Acquiror Shares may trade
following announcement of the Merger or at any future time. We have not undertaken to reaffirm or revise this opinion or otherwise comment upon any events occurring after the date hereof and do not
have any obligation to update, revise or reaffirm this opinion. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
have been engaged by the Company to act as its financial advisor and we will receive a fee from the Company for providing our services, a significant portion of which is contingent
upon the consummation of the Merger. We will also receive a fee for rendering this opinion. The opinion fee is not contingent upon the consummation of the Merger or the conclusions reached in our
opinion. The Company has also agreed to indemnify us against certain liabilities and reimburse us for certain expenses in connection with our services. We are currently engaged to assist the Company's
Board of Directors with strategic and financial alternatives for the Company and have, in the past, provided financial advisory and financing services to a subsidiary of the Company and may continue
to do so on behalf of the Company and its subsidiaries and have received, and may receive, fees for the rendering of such services. In addition, in the ordinary course of our business, we and our
affiliates may actively trade securities of the Company and the Acquiror for our own account or the account of our customers and, accordingly, may at any time hold a long or short position in such
securities. We may also, in the future, provide investment banking and financial advisory services to the Company, the Acquiror or entities that are affiliated with the Company or the Acquiror, for
which we would expect to receive compensation. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This
opinion is provided to the Board of Directors of the Company in connection with its consideration of the Merger and is not intended to be and does not constitute a recommendation to
any stockholder of the Company as to how such stockholder should act or vote with respect to the Merger or any other matter. Except with respect to the use of this opinion in connection with the proxy
statement relating to the Merger in accordance with our engagement letter with the Company, this opinion shall not be disclosed, referred to, published or otherwise used (in whole or in part), nor
shall any public references to us be made, without our prior written approval. This opinion has been approved for issuance by the Piper Jaffray Opinion Committee. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This
opinion addresses solely the fairness, from a financial point of view, to holders of Company Common Stock of the proposed Purchase Price set forth in the Agreement and does not
address any other terms or agreement relating to the Merger or any other terms of the Agreement. We were not requested to opine as to, and this opinion does not address, the basic business decision to
proceed with or effect the Merger, the merits of the Merger relative to any alternative transaction or business strategy that may be available to the Company, Acquiror's ability to fund the Purchase
Price or any other terms contemplated by the Agreement or the fairness of the Merger to any other class of securities, creditor or other constituency of the Company. Furthermore, we express no opinion
with respect to the amount or nature of compensation to any officer, director or employee of any party to
the Merger, or any class of such persons, relative to the Purchase Price to be received by holders of Company Common Stock in the Merger or with respect to the fairness of any such compensation,
including whether such payments are reasonable in the context of the Merger. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Based
upon and subject to the foregoing and based upon such other factors as we consider relevant, it is our opinion that the Purchase Price is fair, from a financial point of view, to
the holders of Company Common Stock (other than the Acquiror and its affiliates, if any) as of the date hereof. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Celldex is a Delaware corporation. In accordance with the Delaware General Corporation Law (the "DGCL"), Article Six of
the registrant's Third Restated Certificate of Incorporation, as amended, provides that no director of the registrant shall be personally liable to the registrant or its stockholders for breach of
fiduciary duty as a director, except for liability (i)&nbsp;for any breach of the director's duty of loyalty to Celldex or its stockholders, (ii)&nbsp;for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of the law, (iii)&nbsp;under Section&nbsp;174 of the DGCL, or (iv)&nbsp;for any transaction from which the director derived an
improper personal benefit. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
DGCL permits, but does not require, a corporation to indemnify its directors, officers, employees or agents and expressly provides that the indemnification provided for under the
DGCL shall not be deemed exclusive of any indemnification right under any bylaw, agreement, vote of stockholders or disinterested directors, or otherwise. The DGCL permits indemnification against
expenses and certain other liabilities arising out of legal actions brought or threatened against such persons for their conduct on behalf of the corporation, provided that each such person acted in
good faith and in a manner that he or she reasonably believed was in or not opposed to the corporation's best interests and in the case of a criminal proceeding, had no reasonable cause to believe his
or her conduct was unlawful. Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to directors and officers of Celldex pursuant to the
foregoing provision or otherwise, Celldex has been advised that, in the opinion of the Securities Exchange Commission, such indemnification is against public policy as expressed in the Securities
Exchange Act of 1934, as amended, and is therefore, unenforceable. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Celldex
currently carries a directors' and officers' liability insurance policy which provides for payment of expenses of Celldex directors and officers in connection with threatened,
pending or completed actions, suits or proceedings against them in their capacities as directors and officers, in accordance with the Bylaws and the DGCL.  </FONT></P>

foregoing provisions, 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 Act
and is, therefore, unenforceable. In the event that 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 such director, officer or controlling person in connection with the securities being
registered, 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 Act and will be governed by the final adjudication of such issue. </FONT></P>
