<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On November&nbsp;29, 2016, Celldex Therapeutics,&nbsp;Inc., a Delaware corporation (&#147;<i>Celldex</i>&#148;), announced that it consummated the transactions contemplated by that certain Agreement and Plan of Merger dated as of November&nbsp;1, 2016 (the &#147;<i>Merger Agreement</i>&#148;) by and among Celldex, Kolltan Pharmaceuticals,&nbsp;Inc., a Delaware corporation (&#147;<i>Kolltan</i>&#148;), Connemara Merger Sub 1 Inc. a Delaware corporation and a wholly-owned subsidiary of Celldex (&#147;<i>Merger Sub 1</i>&#148;) and Connemara Merger Sub 2 LLC., a Delaware limited liability company and a wholly-owned subsidiary of Celldex (&#147;<i>Merger Sub 2</i>&#148; and together with Merger Sub 1, the &#147;<i>Merger Subsidiaries</i>&#148;).</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Upon consummation of the transactions contemplated by the Merger Agreement, Kolltan became a wholly-owned subsidiary of Celldex.&#160; Prior to the merger, Kolltan was a privately-held clinical-stage company focused on the discovery and development of novel, antibody-based drug candidates targeting reception tyrosine kinases, or RTKs. </font>Kolltan&#146;s programs include: (i)&nbsp;KTN0158, a humanized monoclonal antibody that is a potent inhibitor of KIT activation and receptor dimerization in tumor cells and mast cells, which is currently in a Phase 1 dose escalation study in refractory gastrointestinal stromal tumors (GIST); (ii)&nbsp;KTN3379, a human monoclonal antibody designed to block the activity of ErbB3 (HER3), which recently completed a Phase 1b study with combination cohorts where meaningful responses and stable disease were observed in cetuximab (Erbitux<font size="1" style="font-size:6.5pt;position:relative;top:-3.0pt;">&#174;</font>) refractory patients in head and neck squamous cell carcinoma and in BRAF-mutant non-small cell lung cancer (NSCLC); and (iii)&nbsp;a multi-faceted TAM program, a broad antibody discovery effort underway to generate antibodies that modulate the TAM family of RTKs, comprised of Tyro3, AXL and MerTK, which are expressed on tumor-infiltrating macrophages, dendritic cells and some tumors. Research supports TAMs having broad application and potential across immuno-oncology and inflammatory diseases.&#160; Following the merger, the combined company has 209 employees.</p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Under the terms of the Merger Agreement, upon consummation of the transactions contemplated by the Merger Agreement, Kolltan&#146;s investors received, in exchange for their share and debt interests in Kolltan, an aggregate of 18,257,996 shares of Celldex&#146;s common stock with a calculated value of $62.5 million, based on the average closing price of Celldex&#146;s stock for the five trading day period ending on October&nbsp;28, 2016, the third calendar day prior to the date of the Merger Agreement, as adjusted downward pursuant to the terms of the Merger Agreement. The Merger Agreement provides that the number of shares that can be issued at the closing can be increased or decreased by no more than 5% in either direction based on the comparable average closing prices over the five trading days prior to the closing date.&#160; Therefore, because the average closing price of Celldex&#146;s stock over the five trading days prior to the closing date was higher than the comparable average closing prices over the five trading days prior to the date of the Merger Agreement, there was a full 5% downward adjustment in the number of shares issued at closing.&#160; In addition, following closing, certain officers of Kolltan will receive an aggregate of 437,901 shares of Celldex&#146;s common stock in lieu of cash severance obligations owed to them by Kolltan.&#160; In addition, in the event that certain specified preclinical and clinical development milestones related to Kolltan&#146;s development programs and/or Celldex&#146;s development programs and certain commercial milestones related to Kolltan&#146;s product candidates are achieved, Celldex will be required to pay Kolltan&#146;s stockholders milestone payments of up to $172.5 million, which milestone payments may be made, at Celldex&#146;s sole election, in cash, in shares of Celldex&#146;s common stock or a combination of both, subject to NASDAQ listing requirements and provisions of the Merger Agreement.&#160; The number of shares of Celldex common stock issued in connection with a milestone payment, if any, will be determined based on the average closing price per share of Celldex common stock for the five trading day period ending three calendar days prior to the achievement of such milestone. Pursuant to applicable NASDAQ listing rules, Celldex is required to obtain stockholder approval of such issuances of Celldex&#146;s common stock to the extent that such issuances exceed 19.9% of its common stock outstanding prior to the merger.&#160; If Celldex does not obtain stockholder approval of such common stock issuances, Celldex may elect to pay the milestone consideration in cash to maintain compliance with applicable NASDAQ listing standards.&#160; Celldex may still decide to pay cash even if Celldex obtains stockholder approval.</font></p>

Moreover, certain representations and warranties may not be complete or accurate as of a particular date because they are subject to a contractual standard of materiality that is different from those generally applicable to stockholders and/or were used for the purpose of allocating risk among the parties rather than establishing certain matters as facts.

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">HAMPTON, N.J.&#151;November&nbsp;29, 2016&#151;Celldex Therapeutics,&nbsp;Inc. (Nasdaq: CLDX) announced today it has completed its previously announced acquisition of Kolltan Pharmaceuticals,&nbsp;Inc., a privately held company focused on the discovery and development of novel, antibody-based drugs targeting receptor tyrosine kinases (RTKs).</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&#147;Celldex has added a unique platform of antibodies targeting receptor tyrosine kinases, which are validated targets in oncology, to our pipeline. Clinical and preclinical data suggest these candidates can help overcome tumor resistance mechanisms associated with current tyrosine kinase inhibitors and seen in patients who have failed other cancer therapies,&#148; said Anthony Marucci, Co-founder, President and Chief Executive Officer of Celldex. &#147;We believe these programs are highly compatible with our scientific approach and can be developed independently and in combination with Celldex&#146;s existing product candidates. We are finalizing our integrated clinical development strategy and look forward to outlining these plans in the coming weeks.&#148;</font></p>
