(c)           At the Closing, Company and Merger Sub II shall cause a certificate of merger substantially in the form of Exhibit C-2 hereto (the “Second Certificate of Merger”) to be executed, acknowledged and filed with the Secretary of State of the State of Delaware promptly following the filing of the Certificate of Merger and make all other filings or recordings required by the DLLCA in connection with the Second Merger.  The Second Merger shall become effective at such time as the Second Certificate of Merger is duly filed with the Secretary of State of the State of Delaware (the “Second Effective Time”).

(a)           Each share of Company Common Stock and each share of Company Preferred Stock, if any, held immediately prior to the First Effective Time by Parent, Merger Sub or the Company (including shares held in treasury) shall be canceled and extinguished and no payment shall be made with respect thereto (collectively, the “Cancelled Shares”).

(c)           Notwithstanding anything to the contrary contained in this Agreement, in no event will the aggregate number of shares of Parent Common Stock (i) issuable in the Mergers as Closing Merger Consideration, (ii) payable as severance to ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇, ▇▇. or ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, Ph.D., and (iii) issued upon conversion of the New Debt exceed 19.9% of the number of shares of Parent Common Stock outstanding on the trading day immediately before the date hereof (as appropriately adjusted for any reclassification, recapitalization, stock split or combination, exchange or readjustment of shares, or any stock dividend thereon).

(b)           On the Closing Date, Parent shall deliver to the Exchange Agent for exchange and payment in accordance with this Article I shares of Parent Common Stock (which shall be in non-certificated book-entry form) and an amount of cash in U.S. dollars in lieu of fractional shares, if any, of Parent Common Stock sufficient to be issued and paid pursuant to Section 1.05, payable pursuant to the provisions of this Article I, in each case, in accordance with the provisions of an exchange agent agreement to be executed at the First Effective Time in forms reasonably acceptable to the Company.  Parent shall cause the Exchange Agent to make such payments of cash and shares of Parent Common Stock to the Stockholders in accordance with the terms of this Article I.

(c)           At the First Effective Time, (i) all shares of Company Stock outstanding immediately prior to the First Effective Time shall automatically be cancelled and retired and shall cease to exist, (ii) no holder of record of a certificate that immediately prior to the First Effective Time represented outstanding shares of the Company Stock (a “Certificate”) shall have any rights as a stockholder of the Company and (iii) each Certificate (x) representing any outstanding shares of Company Stock shall thereafter represent only the right to receive the Merger Consideration payable in respect of such shares as set forth in this Agreement and any dividends or distributions provided for in Section 1.06(h) below, and (y) representing any Dissenting Shares shall thereafter represent only the right to receive the payments described in Section 1.09.

(d)           Promptly after the First Effective Time (and in any event within five (5) Business Days after the Closing Date), Parent shall cause the Exchange Agent to mail to each holder of record of a Certificate immediately prior to the First Effective Time (i) a letter of transmittal in the form of Exhibit D attached hereto (the “Letter of Transmittal”) specifying that delivery shall be deemed to have occurred, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates (or affidavits of loss containing customary indemnification obligations in lieu thereof) to the Exchange Agent, (ii) instructions for use in effecting the surrender of the Certificates in exchange for payment of the Merger Consideration to which such holder may be entitled pursuant to Section 1.05 hereof and any dividends or distributions provided for in Section 1.06(h) below, (iii) solely with respect to the Persons identified on Exhibit E hereto (such Persons, the “Lock-up Persons”), a lock-up agreement (the “Lock-Up Agreement”) in the form attached hereto as Exhibit F; and (iv) an investor questionnaire (to the extent a completed and executed Investor Questionnaire has not been received by the Company prior to the Closing) in the form attached hereto as Exhibit G (the “Investor Questionnaire”).  Upon surrender of a Certificate for cancellation to the Exchange Agent (or delivery of affidavits of loss in lieu thereof), together with such Letter of Transmittal, Investor Questionnaire and, solely in the case of the Lock-up Persons, a Lock-Up Agreement, each duly executed and completed in accordance with the instructions thereto, the holder of such Certificate shall be entitled to receive in exchange therefor a payment of the applicable amount of Merger Consideration provided in Section 1.05 with respect to such Certificate and any dividends or distributions provided for in Section 1.06(h) below and the Certificate so surrendered shall forthwith be cancelled.  Parent shall, as promptly as practicable after receipt of each properly surrendered Certificate (or affidavits of loss in lieu thereof), cause the Exchange Agent to issue to such Stockholder the Closing Merger Shares (and cash in lieu of fractional shares, if any) representing that portion of the Closing Merger Consideration to which such Stockholder is entitled pursuant to Section 1.05, together with any dividends or distributions provided for in Section 1.06(h) below.  To each holder of a properly surrendered Certificate (or affidavit of loss containing customary indemnification

5

obligations delivered in lieu thereof), at the time and in the manner set forth in Section 1.05 and Section 1.08, Parent shall cause the Exchange Agent to, as applicable (i) pay the applicable amount of the Milestone Consideration provided in Section 1.08 to such holder, in cash, by wire transfer of immediately available funds to the account designated by such holder in the Letter of Transmittal delivered with such Certificate (or affidavit in lieu thereof), and (ii) issue to such Stockholder any shares of Parent Common Stock representing that portion of the Milestone Consideration to which such Stockholder is entitled pursuant to Section 1.05 and Section 1.08.  The Stockholders Representative shall provide the Parent with directions, in the form of an updated Consideration Spreadsheet, for further delivery to the Exchange Agent, as to whom, and the amount, to be paid to each Stockholder with respect to such Milestone Payment (recognizing that such instructions may change with respect to each Milestone Payment).  The Exchange Agent shall rely upon all tax forms used and collected by the Exchange Agent in connection with all payments made at Closing. If reasonably requested by Exchange Agent, Parent shall provide any additional information in its possession necessary to complete the required tax reporting. Until so surrendered, each outstanding Certificate that prior to the First Effective Time represented shares of Company Stock (other than Dissenting Shares) will be deemed from and after the First Effective Time, for all purposes, to evidence the right to receive payments of the applicable amounts provided in Sections 1.05 and 1.08, together with any dividends or distributions provided for in Section 1.06(h) below.  If, after the First Effective Time, any Certificate is presented to the Exchange Agent, Surviving Company or Parent, it shall be cancelled and exchanged as provided in this Section 1.06.  No interest shall be paid or accrued after the First Effective Time on any amount payable upon due surrender of the Certificates.  If payment is to be made to a Person other than the registered holder of the Certificate surrendered (or for which an affidavit of loss was delivered), it shall be a condition of such payment that the Certificate so surrendered (or affidavit of loss) shall be properly endorsed or otherwise in proper form for transfer and that the Person requesting such payment shall pay any transfer or other Taxes required by reason of the payment to a Person other than the registered holder of the Certificate surrendered or establish to the satisfaction of the Exchange Agent that such Tax was paid or is not applicable.

(e)           At the First Effective Time, the stock transfer books of the Company shall be closed, and there shall thereafter be no further registration of transfers of shares of Company Stock outstanding immediately prior to the First Effective Time on the records of the Company.  After the First Effective Time, no transfer of Company Stock shall thereafter be made on the stock transfer books of the Surviving Company or otherwise.  From and after the First Effective Time, the holders of Certificates representing such shares outstanding immediately prior to the First Effective Time shall cease to have any rights with respect to such shares except as otherwise provided herein or by any applicable Laws.

(f)            Any portion of the funds received by the Exchange Agent (including the proceeds of any investments thereof) which remains unclaimed by the Stockholders for one (1) year after the date of payment to the Exchange Agent shall be delivered to the Surviving Company.  Any Company Stockholder that has not theretofore surrendered any Certificate and submitted a Letter of Transmittal, Investor Questionnaire and, if applicable, a Lock-Up Agreement, in accordance with the requirements set forth therein and in this Article I, or otherwise received any portion of the Merger Consideration due and payable to such Stockholder pursuant to this Agreement, shall thereafter look only to Parent and the Surviving Company for payment of the applicable portion of the Merger Consideration upon due surrender of any applicable Certificate (or effective affidavits of loss in lieu thereof).

(g)           No Fractional Shares.  No certificate or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of Parent.  Each holder of shares of Company Stock converted pursuant to the First Merger who would otherwise have been

6

entitled to receive a fraction of a share of Parent Common Stock (after taking into account all Certificates delivered by such holder and the aggregate number of shares of Company Stock represented thereby) shall receive, in lieu thereof, cash (without interest and subject to applicable Tax withholding) in an amount equal to such fractional part of a share of Parent Common Stock multiplied by the Average Closing Price (in the case of Closing Merger Consideration), or the applicable Parent Stock Value (in the case of a Milestone Payment).

(h)           Distributions with Respect to Un-Exchanged Certificates.  No dividends or other distributions declared or made after the First Effective Time with respect to Parent Common Stock with a record date after the First Effective Time shall be paid to the holder of any un-surrendered Certificate until the holder of record of such Certificate shall surrender such Certificate in accordance with this Section 1.06.  Subject to the effect of applicable laws, following surrender of any such Certificate, there shall be issued and paid to the record holder of the Certificate, at the time of such surrender, the amount of dividends or other distributions with a record date after the First Effective Time previously paid with respect to such whole shares of Parent Common Stock, without interest, and at the appropriate payment date, the amount of dividends or other distributions having a record date after the First Effective Time but prior to surrender and a payment date subsequent to surrender that are payable with respect to such whole shares of Parent Common Stock.

1.07            Lost, Stolen or Destroyed Certificates .  In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by such record holder, Parent shall cause the Exchange Agent to pay to the record holder of such Certificate the applicable amounts of the Merger Consideration provided in Section 1.05 (together with any dividends or distributions provided for in Section 1.06(h) above) to be paid in respect of the shares represented by such Certificate pursuant to this Agreement; provided, however, that the Surviving Company may, in its discretion and as a condition precedent to the payment of such consideration, require such record holder to indemnify the Surviving Company against any claim that may be made against the Surviving Company with respect to such Certificate.

c)             If the Kolltan Product component of the Combination Product is not sold separately in such country, but the Other Active(s) are sold separately in such country, Net Sales shall be calculated by multiplying actual Net Sales of such Combination Product in such country as determined under the first paragraph of this Section 1.08(a)(xvi) by the fraction (C-D)/C, where C is the net invoice price of the Combination Product in such country, and D is the sum of the net invoice prices charged for the Other Active(s) in the Combination Product in such country.

d)            If none of the Kolltan Product component and the Other Active(s) are sold separately in such country, Net Sales for the purpose of determining royalties due hereunder for the Combination Product shall be reasonably determined in good faith by Parent taking into account the perceived relative value contributions of the Kolltan Product portion of the Combination Product and the Other Active(s) in the Combination Product.

9

For clarification, sale of Kolltan Product by Parent, its Affiliates or a Product Transferee to a Related Party for resale shall not be deemed a sale for purposes of this definition of “Net Sales,” provided that the subsequent resale to the first third party that is not a Related Party of Parent, its Affiliates or a Product Transferee is included in the computation of Net Sales.  Further, transfers or dispositions of Kolltan Product, without consideration: (A) in connection with patient assistance programs; (B) for charitable or promotional purposes; (C) for preclinical, clinical, regulatory or governmental purposes or under so-called “named patient” or other limited access programs; or (D) for use in any tests or studies reasonably necessary to comply with Law, regulation or request by a Regulatory Authority, shall not, in each case of (A) through (D), be deemed sales of such Kolltan Product for purposes of this definition of “Net Sales.”

(xvii)     “Other Active” shall mean any active pharmaceutical ingredient that is not a Kolltan Compound.

(xviii)    “Parent Stock Value” means, in the case of any Milestone Payment with respect to the achievement of the applicable Milestone, the average of the closing sale prices per share of Parent Common Stock as reported on the Nasdaq (or other national exchange upon which the Parent Common Stock is then listed) for the five (5) trading day period ending three (3) calendar days prior to the date such Milestone is achieved (as adjusted, if applicable and appropriate, to reflect any reclassification, stock split, reverse stock split, dividend, distribution or other like change with respect to Parent Common Stock effected (or for which a record date is established) on or after the first day of such five (5) trading day period and on or prior to the date such Milestone is achieved). In the event that (i) the Parent Common Stock is no longer listed on Nasdaq or another national exchange (whether as a result of a merger of Parent into another Person, the acquisition of Parent or otherwise) and (ii) the common stock of Parent’s acquirer or successor-in-interest is listed on Nasdaq or another national exchange, then such common stock shall be deemed to be Parent Common Stock for the purposes of this Agreement, including calculating the Parent Stock Value. In the event that at the time of the Milestone Payment, if any, the Parent Common Stock or the common stock of the Parent’s successor in interest, if any, is no longer listed on the Nasdaq or any other national exchange, the Parent Stock Value shall be the fair market value thereof as reasonably determined in good faith by the board of the Parent or its successor in interest, as the case may be.

(xix)      “Partnership Agreement” means, with respect to any Surviving Company Asset, a collaboration, joint venture or other similar arrangement with a third party entered into after the First Effective Time which provides both parties to such arrangement with an economic interest in the commercialization of such asset based upon a sharing of revenues or profits deriving from such asset through commercialization or by way of receiving payments (fixed in amount or otherwise) upon the occurrence of certain events in connection with commercialization of such asset.  For the avoidance of doubt, “Partnership Agreement” shall not include fee for service or comparable arrangements that do not involve a sharing of risks and benefits associated with the development and commercialization of a Surviving Company Asset.

(xx)       “Phase I Clinical Trial” means a human clinical trial, the principal purpose of which is a determination of safety, as described in 21 C.F.R. 312.21(a) or its successor regulation, including any equivalent clinical trial conducted in any country other than the United States.

(xxi)      “Phase II Clinical Trial” means a human clinical trial conducted to evaluate the effectiveness of a drug for a particular indication or indications in patients with the disease or condition under study and to determine the common short-term side effects and risks associated with the drug, as further described in 21 C.F.R. § 312.21(b) or its successor regulation, including any equivalent clinical trial conducted in any country other than the United States.  For clarity, “Phase II Clinical Trial” includes the Phase II portion of any phase I/II Clinical Trial and a Phase II(b) Clinical Trial refers to a second well-controlled Phase II Clinical Trial specifically designed to

10

evaluate efficacy for a particular indication or indications after an evaluation of safety and effectiveness has been performed based on a Phase II Clinical Trial.

(xxii)     “Phase III Clinical Trial” means a human clinical trial conducted to gather the additional information about effectiveness and safety that is needed to evaluate the overall benefit-risk relationship of the drug and to provide an adequate basis for physician labeling, as further described in 21 C.F.R. § 312.21(c) or its successor regulation, including any equivalent clinical trial conducted in any country other than the United States

(xxiii)    “Product Transferee” means any successor of Parent or any of its Affiliates, and/or any other Person who obtains from Parent or an Affiliate of Parent, any rights to develop and/or commercialize any Surviving Company Compound or any Surviving Company Product in a particular field or territory, whether by assignment, license, sublicense or any other grant or transfer of rights.

(xxiv)   “Related Party” means Parent, its Affiliates and any Product Transferee.

(xxv)    “Successful Completion” means, with respect to a Clinical Trial, achievement of the primary or secondary study endpoints, or other relevant results, of such Clinical Trial, as determined on the date that is the earlier of (A) (I) in the case of a Clinical Trial involving Kolltan Compounds, three (3) months following the database lock for such Clinical Trial, and (II) in the case of a Clinical Trial involving a Celldex Compound or Celldex Early Stage Compound, six (6) months following the database lock for such Clinical Trial or (B) public disclosure of any results of such Clinical Trial, in each case such that continued development of such Surviving Company Compound is warranted on the basis of the use of Commercially Reasonable Efforts.  Database lock would occur when a reasonable level of follow-up has been achieved to satisfy a positive or a negative determination of the primary endpoint of the study.  In the case of a pre-clinical study, Successful Completion shall mean the achievement of data (to be reviewed as promptly as practicable following its generation) which warrants the continuation of research efforts through the use of Commercially Reasonable Efforts.

(xxvi)   “Surviving Company Assets” means the Surviving Company Compounds and the Surviving Company Products.

(xxvii)  “Surviving Company Compound” means the Kolltan Compounds, the Celldex Compounds and the Celldex Early Stage Compounds.

(xxviii) “Surviving Company Product” means any pharmaceutical product or combination of co-administered pharmaceutical products that contain(s) any Surviving Company Compound as an active pharmaceutical ingredient, alone or in combination with one or more additional active pharmaceutical ingredients and including all formulations and line extensions thereof.

(xxix)   “TAM Program” means a research and development program relating to the antibody-based molecules targeting (A) one or more of the TAM RTK family members, those being Tyro3, Axl or MerTK, or (B) the ligand GAS6.

(xxx)    “Third-Party Payments” means, with respect to any Kolltan Product, any amounts that Parent, its Affiliates and/or Product Transferees are required to pay to a third party under agreements for patent rights or other intellectual property or technology reasonably required for a Kolltan Product and/or the development, manufacture, use, sale and/or offer for sale thereof or under agreements pursuant to which revenues or profits from the sale and distribution of a Kolltan Product  are shared with a co-promotion or other collaboration partner.

11

(xxxi)   “Upfront Payments” means, with respect to TAM Partnerships, if any, any compensation received (whether in cash, debt, equity or otherwise) by Parent or its Affiliates from the applicable third-party partner in connection with entering into or closing any such TAM Partnerships.

(b)      Milestone Payments.  Parent shall pay (or cause to be paid) to the Exchange Agent, for further distribution to the Stockholders, in accordance with and subject to the terms of Section 1.05, this Section 1.08 and Section 7.06 the following payments (each, a “Milestone Payment”) upon the achievement of the following milestone events set forth in Sections 1.08(b)(i) — 1.08(b)(iii) below by Parent, any of its Affiliates or Product Transferees after the Closing Date (each, a “Milestone”):

(i)    Development Milestones.

(ii)   Commercial Milestones.

(iii)  Other Milestones. In the event that Parent or Surviving Company enters into or closes one or more Partnership Agreements with respect to the TAM Program (each, a “TAM Partnership”) within eighteen (18) months after the Closing, or in the event that Parent or Surviving Company enters into or closes one or more TAM Partnerships within the six (6) months immediately thereafter with a third party with whom Parent or the Surviving Company was in negotiations or discussions during the initial eighteen (18) month period, then the Stockholders shall receive a payment equal to fifty percent (50%) of any Upfront Payments received by Parent or its Affiliates under the terms of each TAM Partnership; provided, however, that any such payments shall not exceed $10.0 million in the aggregate.

12

For the avoidance of doubt, each Milestone may be achieved only once and each Milestone Payment may be paid only one time, if at all. In addition, the first Milestone Payment to be paid (x) shall be accompanied by payment of the Closing Shortfall, if any, and (y) shall be reduced by Two Million Five Hundred Thousand Dollars ($2,500,000).

(c)        Payment of Milestone Payments.

(i)       Form of Payment.  Any Milestone Payment shall be payable at Parent’s sole election in cash, in shares of Parent Common Stock based on the Parent Stock Value, or a combination of both. Notwithstanding the preceding sentence, Parent agrees to use commercially reasonable efforts to cause a sufficient portion of each Milestone Payment and any payment due to Stockholders in connection with Section 1.13 to be paid in Parent Common Stock such that the Mergers will satisfy the “continuity of interest” requirements set forth in Treasury Regulation Section 1.368-1(e) and other applicable Law.  In furtherance thereof, Parent agrees to use commercially reasonable efforts to obtain, at the Parent’s 2017 annual stockholder meeting scheduled to commence in June of 2017, but in any event prior to August 31, 2017, any consent of the shareholders of Parent required to permit the issuance of sufficient Parent Common Stock in satisfaction of the Milestone Payments such that the Merger Consideration will so be comprised.  Any Stockholder that is unable to deliver an Investor Questionnaire with its Letter of Transmittal certifying such Stockholder’s status as an Accredited Investor shall not be entitled to any Milestone Consideration Shares, unless otherwise determined by Parent, but instead shall be paid cash in lieu of Milestone Consideration Shares; provided that, the allocation and distribution of Milestone Consideration shall be in compliance with Section 1.05 but with such Stockholder only receiving cash by wire of immediately available funds to an account designated in writing by such Stockholder.  In the event that any cash payment is made in lieu of the issuance of any Milestone Consideration Shares, Parent shall at all times take into account its obligations set forth above in this Section 1.08(c)(i) with respect to issuing a minimum percentage of the Merger Consideration in the aggregate, determined by value, in the form of Parent Common Stock.

(ii)      Notice of Achievement. Parent shall notify Stockholders Representative in writing of the achievement of each Milestone by Parent, its Affiliate, or a Product Transferee within ten (10) Business Days after the date of achievement of such Milestone (each, a “Milestone Notice”); provided that, with respect to the First Kolltan Commercial Milestone, the Milestone Notice, if any, shall be due to the Stockholders Representative within thirty (30) days of the end of the calendar month in which the First Kolltan Commercial Milestone is achieved.

(iii)     Delivery of Milestone Payments.  Subject to the provisions of Section 7.06, within ten (10) days following the delivery by Parent of the Milestone Notice related to the achievement of any Milestone, Parent shall deliver, or cause to be delivered, to the Exchange Agent, for further distribution to the applicable Stockholders, the total amount of the Milestone Payment, and shall cause the Exchange Agent to make such distributions. The Exchange Agent shall be responsible for distributing each Milestone Payment it receives, if any, to each Stockholder in accordance with an allocation (determined in accordance with Section 1.05) provided for such Milestone Payment by the Stockholders Representative.

(iv)     Adjustments.  Each Milestone Payment shall be subject to adjustment pursuant to the terms of Section 7.06 below.

(d)        Parent Obligations.

(i)       Commercially Reasonable Efforts.  During the Efforts Period, Parent shall, directly and/or through its Affiliates and/or Product Transferees, use Commercially Reasonable Efforts to develop and commercialize the Surviving Company Assets.  For the avoidance of doubt: (A) activities performed by or on behalf of

13

Parent’s Affiliates, and/or any Product Transferees and/or other contractors engaged by Parent (or any of its Affiliates or Product Transferees, as the case may be), shall be deemed to be activities performed by Parent for the purposes of assessing Parent’s fulfillment of its obligations under the preceding sentence to use Commercially Reasonable Efforts; (B) the obligations to use Commercially Reasonable Efforts set forth in this Section 1.08(d) shall not be deemed a representation, warranty, or guarantee that any Milestone will be achieved; (C)  Parent and the Surviving Company shall have sole discretion (but acting reasonably) over all matters relating to the Surviving Company Assets after the First Effective Time, including, but not limited to, any research, development, manufacturing, commercialization, clinical trial design, site selection, regulatory, quality standards, legal, intellectual property rights, marketing, licensing and sales decisions relating to the Surviving Company Assets; and (D) neither Parent nor the Surviving Company owes any fiduciary duty or express or implied duty to any Stockholder, and Parent hereby disclaims (on behalf of itself and its Affiliates and Product Transferees), and the Stockholders Representative (on behalf of the Stockholders) hereby irrevocably waives, any obligations with respect to development, seeking Marketing Approval for, or commercialization of, any Surviving Company Asset, or the achievement of any of the Milestones, whether arising under applicable Law or otherwise, except in the cases of each of clauses (A), (B), (C) and (D) above for the obligation to use Commercially Reasonable Efforts set forth in the first sentence of this Section 1.08(d)(i).

(e)           Milestone Abandonment.  In the event that Parent determines in good faith that a Milestone will not be achieved, Parent shall promptly notify the Stockholders Representative in writing of such determination (any such notice, a “Milestone Abandonment Notice”).  Upon the Stockholders Representative’s written request, Parent shall make available a representative of Parent with direct responsibility for the development of the Surviving Company Asset to which the abandoned Milestone relates and such other of its employees as Parent may reasonably deem appropriate, who will respond to reasonable inquiries of the Stockholders Representative with respect to such Milestone Abandonment Notice.  The Milestone Abandonment Notice shall specify in reasonable detail the reasons the applicable determination was made.

(f)            Disposal Restrictions. During the Efforts Period, neither Parent nor its Affiliates (including the Surviving Company) shall transfer, sell, license or assign, to any third Person who is not an Affiliate of Parent, all or any rights pertaining to the Surviving Company Assets, including as a part of a sale that includes all or any of the assets of the Surviving Company or all of the equity interests of, or a merger with, the Surviving Company, unless the transferee, licensee or assignee, as applicable, of such transfer, sale, license or assignment is reasonably determined to be financially capable of performing, and has the experience or expertise to perform, the obligations of Parent and such entity assumes the obligations of Parent under this Section 1.08, including payment of the Milestone Payments (except to the extent previously paid), in a writing in form and substance reasonably satisfactory to the Stockholders Representative and thereafter Parent shall no longer be responsible for the performance of such obligations.

(g)           Milestone Payments Not Certain.  Without limiting Parent’s obligations under this Section 1.08, each of Parent, on the one hand, and the Company and the Stockholders Representative (on behalf of themselves and each of the Stockholders), on the other, hereby acknowledge that the achievement of any Milestone is uncertain and it is therefore not assured that Parent will be required to pay (or cause to be paid) any Milestone Payment at all if no Milestone described in Section 1.08(b) is achieved by Parent, or any of its Affiliates or Product Transferees.

(h)           Milestone Payments Not a Security. The Parties do not intend the right of the Stockholders to receive any Milestone Payment to be a security.  Accordingly, the right of a Stockholder to receive any Milestone Payment (1) shall not be represented by a certificate, (2) does not represent an ownership interest in Parent or the Surviving Company, and (3) does not entitle a Stockholder to any rights

14

common to equity holders of Parent or the Surviving Company, other than as expressly set forth herein.  The right of a Stockholder to receive Milestone Payments pursuant to this Agreement shall not be transferable without the prior written consent of Parent, which consent shall not be unreasonably withheld, conditioned or delayed.  Any attempted or purported transfer in violation of this Section 1.08(h) will be null and void.

(i)            Stockholders Representative Audit Rights. Stockholders Representative, through its authorized employees, representatives, agents, partners and consultants, upon giving reasonable notice to Parent, shall have the right, upon reasonable advance notice and at its or the Stockholders’ sole expense, and during normal business hours, no more frequently than twice per calendar year, (A) to inspect at reasonable times and at reasonable places, all facilities, equipment, procedures, and practices employed by Parent or its Affiliates in connection with any matter relating any activity that could reasonably be related to, or could reasonably lead to, achievement of any Milestone or payment of any Milestone Payment or relates to the basis or facts upon which any Milestone is or is not achieved, any Milestone Payment is or is not earned, or any indemnification, holdback or set off claim against any Milestone Payment is made (the “Contingency Activities”), and (B) to examine and audit all books, records, files, notebooks, relevant operating procedures, and data of Parent and its Affiliates relating to (i) the Contingency Activities, including to assess the status of such activities and to assess whether any Milestone Payments should be paid, (ii) any indemnification or set-off claims pursuant to Article VII, including to determine the facts and circumstances thereof, and (iii) Parent and its Affiliates’ compliance with this Agreement.  The foregoing includes the right to speak to key personnel related to any Contingency Activity.  Any such inspection examination or audit shall be subject to appropriate and customary obligations of confidentiality and non-use and may only be performed by such entities and personnel to which Parent has no reasonable objection; provided, however, that the foregoing shall not restrict the Stockholders Representative from communicating information to the Stockholders to the extent reasonably necessary to the performance of its duties as the Stockholders Representative, subject to appropriate and customary undertakings of confidentiality and non-use.

1.09            Dissenting Shares.  Notwithstanding anything in this Agreement to the contrary and to the extent available under Section 262 of the DGCL, any share of Company Stock that is issued and outstanding immediately prior to the First Effective Time and that is held by a Company Common Stockholder or Company Preferred Stockholder who did not consent to or vote (by a valid and enforceable proxy or otherwise) in favor of the adoption of this Agreement, which Company Common Stockholder or Company Preferred Stockholder complies with all of the provisions of the DGCL relevant to the exercise and perfection of appraisal rights (such share being a “Dissenting Share,” and such Company Common Stockholder or Company Preferred Stockholder being a “Dissenting Stockholder”), shall not be converted into the right to receive the Merger Consideration to which the holder of such share of Company Stock would be entitled pursuant to Section 1.05 but rather shall be converted into the right to receive such consideration as may be determined to be due with respect to such Dissenting Share pursuant to Section 262 of the DGCL.  If any Dissenting Stockholder fails to perfect its appraisal rights under the DGCL or effectively withdraws or otherwise loses such rights with respect to any Dissenting Shares, such Dissenting Shares shall thereupon automatically be converted into the right to receive the Merger Consideration referred to in Section 1.05 (together with any dividends or distributions provided for in Section 1.06(h) above).  Notwithstanding anything to the contrary contained in this Agreement, if the First Merger is rescinded or abandoned, then the right of a Dissenting Stockholder to be paid the fair value of such holder’s Dissenting Shares pursuant to Section 262 of the DGCL shall cease.  The Company shall give Parent (a) notice of any demand for payment of the fair value of any shares of Company Stock or any attempted withdrawal of any such demand for payment and any other instrument served pursuant to the DGCL and received by the Company relating to any Stockholder’s appraisal rights and (b) the opportunity to participate in all negotiations and proceedings with respect to any such demands for payment under the DGCL.  The Company shall not (x) voluntarily make any

15

payment with respect to any demand for appraisal with respect to any Dissenting Shares and/or (y) offer to settle or settle any demand, in either case, without the prior written consent of Parent (which consent shall not be unreasonably conditioned, withheld or delayed).

1.10            Updated Consideration Spreadsheet and New Debt Conversion Spreadsheet.  At least five (5) Business Days prior to the Closing Date, the Company shall deliver to Parent an updated Consideration Spreadsheet and updated New Debt Conversion Spreadsheet, which updated Consideration Spreadsheet and updated New Debt Conversion Spreadsheet shall include any reasonable comments from Parent.  The Consideration Spreadsheet may continue to be updated following Closing by the Stockholders Representative for the benefit of the Stockholders in connection with any distribution of Merger Consideration to be made after the Closing Date.

1.11            Closing Cash Certificate.  At least three (3) Business Days prior to the Closing Date, the Company shall deliver to Parent a certificate (the “Closing Cash Certificate”), signed by its chief executive officer (in his capacity as such), certifying the Company’s good faith estimate of the Closing Cash (such estimate, as adjusted pursuant to the next sentence of this Section 1.11 “Estimated Closing Cash”), with reasonably detailed documentation supporting such amount. If prior to the Closing Date, Parent disputes all or any portion of the Closing Cash Certificate, an authorized officer of the Company and Parent shall promptly meet and seek in good faith to resolve the dispute(s) and if and to the extent that the Company and Parent are unable to resolve any such dispute(s), then the amount of the disputed item(s) so asserted by Parent in good faith shall be deemed to be the amount included as part of the Closing Cash Certificate for all purposes of this Agreement, including the calculation of the Closing Merger Consideration.

1.12        Final Calculations; Disputes.

(a)           As promptly as practicable following Closing, but in any event within six (6) months after the Closing Date, Parent will deliver a reasonably detailed statement setting forth Parent’s calculations of the Closing Cash (the “Closing Statement”).  After delivery of the Closing Statement, the Stockholders Representative and its accountants shall be permitted reasonable access during normal business hours to review the Company’s books and records and any work papers (including any work papers of Parent’s and the Company’s accountants) related to the preparation of the Closing Statement, subject to such confidentiality restrictions as the accountants shall reasonably request.  The Stockholders Representative and its accountants may make reasonable inquiries of Parent, the Surviving Company and their accountants and employees regarding questions concerning or disagreements with the Closing Statement arising in the course of their review thereof, and Parent shall use, and shall cause the Surviving Company to use, its commercially reasonable efforts to cause any such accountants and employees to cooperate with and respond to such inquiries.

(b)           If the Stockholders Representative has any objections to the Closing Statement, the Stockholders Representative shall deliver a written notice to Parent (the “Dispute Notice”) setting forth the basis for such objections in reasonable detail, including, to the extent practicable, (i) each item or amount on the Closing Statement to which the Stockholders Representative objects, and (ii) the Stockholders Representative’s calculation of each such objected item or amount.  If a Dispute Notice is not delivered to Parent within forty five (45) days after the Stockholders Representative’s receipt of the Closing Statement, the Stockholders Representative shall be deemed to have irrevocably consented to and accepted as final, on behalf of the Stockholders, the Closing Statement and the Closing Statement shall be final, binding and non-appealable by the Parties.  If a Dispute Notice is delivered to Parent within forty five (45) days after the Stockholders Representative’s receipt of the Closing Statement, the Stockholders Representative and Parent

16

shall negotiate in good faith to resolve any objections set forth in the Dispute Notice, but if they do not reach a final resolution within thirty (30) days after the delivery of the Dispute Notice, the Stockholders Representative and Parent shall submit such dispute to an independent accountant of nationally recognized standing reasonably satisfactory to Parent and the Stockholders Representative (who shall not be either party’s independent registered public accounting firm) (the “Independent Accountant”).  If any dispute is submitted to the Independent Accountant, each of Parent and the Stockholders Representative will furnish to the Independent Accountant such work papers and other documents and information relating to the disputed issues as the Independent Accountant may reasonably request and are available to such Party or its accountants (including information of the Company) and each of Parent and the Stockholders Representative shall be entitled to present the Independent Accountant material relating to its determination of the Closing Statement and to discuss, whether or not in the presence of any other Party, its determination of the Closing Statement with the Independent Accountant.

(c)           The Independent Accountant shall resolve only those matters that remain in dispute after the thirty (30) day resolution period.  It is the intent of Parent and the Stockholders Representative that the process set forth in this Section 1.12 and the activities of the Independent Accountant in connection herewith are not intended to be and, in fact are not, arbitration and that the Independent Accountant shall act solely as an auditor and not an arbitrator and no formal arbitration rules shall be followed (including rules with respect to procedures and discovery).  The Stockholders Representative and Parent shall use their commercially reasonable efforts to cause the Independent Accountant to resolve all such disagreements as soon as practicable but in no event later than forty-five (45) days after submission of the disputed issues to the Independent Accountant.  The resolution of the dispute by the Independent Accountant shall be final, binding upon the Parties and non-appealable by either of the Parties.  The Closing Statement shall be modified if necessary to reflect the Independent Accountant’s determination.  The fees and expenses of the Independent Accountant shall be borne by Parent, on the one hand, and the Stockholders Representative, on behalf of the Stockholders, on the other hand, in inverse proportion as they may prevail on the matters resolved by the Independent Accountant, which proportionate allocation shall be calculated on an aggregate basis based on the relative dollar values of the amounts in dispute and shall be determined by the Independent Accountant at the time the determination is rendered on the merits of the matters submitted to the Independent Accountant.

17

1.13                                    Adjustments.  Subject to Parent’s right to terminate under Section 9.01(g), if Estimated Closing Cash is less than negative four million five hundred thousand dollars (-$4,500,000), then Parent shall be entitled to reduce the Consideration Amount dollar-for-dollar to the extent the Estimated Closing Cash amount is less than negative four million five hundred thousand dollars (-$4,500,000).  In the event that (a) Estimated Closing Cash is less than negative four million five hundred thousand dollars (-$4,500,000), and (b) the Closing Cash amount, as finally determined by Section 1.12 is less than the Estimated Closing Cash amount, then Parent shall be entitled to set-off from any Milestone Consideration (but not against any Milestone Consideration for which payment to the Exchange Agent for further distribution to the Stockholders is past due)  payable to the Stockholders hereunder by such difference.  In the event that (x) Estimated Closing Cash is less than negative four million five hundred thousand dollars (-$4,500,000), and (y) the Closing Cash amount, as finally determined by Section 1.12 is greater than the Estimated Closing Cash amount, then Parent shall pay such difference (not to exceed the difference between Estimated Closing Cash and negative four million five hundred thousand dollars (-$4,500,000)) to the Exchange Agent for the benefit of the Stockholders at the time of payment of the next Milestone Payment to be paid after final determination of the Closing Cash as contemplated by Section 1.12. Subject to the requirements Section 1.08(c)(i) with respect to continuity of interest, any amount due to Stockholders in accordance with the preceding sentence shall be payable at Parent’s sole election in cash, in shares of Parent Common Stock based on the Parent Stock Value, or a combination of both.

1.14                                    Transaction Expenses.

(a)                                 No later than three (3) Business Days prior to the Closing Date, the Company shall provide to Parent the amount, in the aggregate, of all Transaction Expenses that have not been paid prior to Closing and shall provide Parent with a certificate setting forth (a) the identity of each Person that is owed such amounts; (b) the amount owed or to be owed to each such Person; and (c) the bank account and wire transfer information for each such Person.  The Parent shall pay all Transaction Expenses at the Closing. Parent shall also issue and deliver the Severance Shares to the intended recipients thereof at the Closing (the number of Severance Shares shall be determined using the same ratio and methodology as is used to calculate the Closing Merger Shares).

(b)                                 The Company shall have paid off and have no Indebtedness (other than the New Debt) as of the Closing Date.  The New Debt shall be converted into shares of Parent Common Stock (any such shares, the “New Debt Conversion Shares”) effective as of immediately following the Closing.

1.15                                    Withholding Rights.  Parent and the Surviving Company shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement to any Stockholder such amounts as are required to be deducted and withheld under any applicable provision of federal, state, local or foreign Tax Law.  To the extent that amounts are so withheld by Parent or the Surviving Company in accordance with the foregoing and paid over to the applicable Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Stockholder in respect of which such deduction and withholding was made.

1.16                                    Taking of Further Action.  If, at any time after the First Effective Time, any further action is necessary or desirable to carry out the purposes of this Article I and to vest the Surviving Company with full right, title and possession to all assets, rights, privileges, powers and franchises of the Company, Merger Sub and Merger Sub II, Parent and the Surviving Company are fully authorized in their respective names to take, and shall take, all such necessary or desirable action, so long as such action is not inconsistent with this Agreement, and all such action as may be required by Law.

18

1.17                                    Treatment of Options.

(a)                                 The Company shall take all action reasonably necessary to cause all Options issued by the Company to have been exercised or terminated no later than immediately prior to the First Effective Time.

(b)                                 The cancellation of an Option as provided above shall be deemed a release of any and all rights the holder thereof had or may have had in respect of such Option.

(c)                                  Prior to the Closing Date, the Board of Directors of the Company (or the compensation committee of the Company, as applicable), shall take all actions as may be reasonably necessary or required in accordance with applicable Laws, the Company Stock Plans or the award agreements applicable to such Options to effectuate all of the actions contemplated by this Section 1.17, including giving any required notice under the Company Stock Plan.

1.18                                    Specified Stockholder Support Agreements.  Concurrently with the execution of this Agreement, Company shall deliver to Parent a duly executed Support Agreement from the Stockholders set forth on Exhibit A (the “Specified Stockholders”).

ARTICLE II

44

discussions or negotiations regarding, or furnish to any Person (other than Parent or any of its Affiliates or Representatives) any non-public information for the purpose of encouraging or facilitating, any Company Acquisition Proposal, (iii) withdraw or modify in any manner adverse to Parent, the recommendation of its Board of Directors that the stockholders of the Company adopt this Agreement, or recommend, adopt or approve any Company Acquisition Proposal (any of the foregoing in this clause (iii), a “Recommendation Withdrawal”), (iv) grant (other than to Parent or any of its Affiliates or Representatives) any waiver or release under any standstill or similar agreement (except that the Company may grant a limited waiver of any provision of any such standstill or similar agreement solely to the extent necessary to permit a Person to submit a Company Acquisition Proposal), or (v) enter into any letter of intent or similar document or any understanding or agreement contemplating or otherwise relating to, or that is intended to or could reasonably be expected to lead to, any Company Acquisition Proposal.  The Company shall promptly (and in any event within one Business Day) notify Parent orally, with written confirmation to follow, of the Company’s receipt of any written Company Acquisition Proposal, which notice shall identify, except to the extent prohibited by a confidentiality agreement in existence as of the date hereof, the name of the Person making such Company Acquisition Proposal and the material terms and conditions of such Company Acquisition Proposal.

45

(c)                                  Any violation of this Section 4.03 by any of the Company’s Representatives shall be deemed to be a material breach of this Agreement by the Company.

Any such Recommendation Withdrawal or the entry by the Company into any Acquisition Agreement shall not change the approval of the Company Board of Directors for purposes of causing any state takeover statute or other state Law to be applicable to the Mergers.

(e)                                  Prior to the adoption of this Agreement by the requisite Stockholder Consent, the Company may terminate this Agreement and enter into an Acquisition Agreement with respect to a Superior Proposal, provided that, prior to any such termination, (i) the Company shall have provided Parent written notice that it intends to terminate this Agreement pursuant to this Section 4.03(e), identifying the Superior Proposal then determined to be more favorable, the parties thereto and the material terms and conditions of the Acquisition Agreement, (ii) within a period of three full Business Days following the delivery of the notice referred to in clause (i) above, Parent shall not have proposed adjustments in the terms and conditions of this Agreement which, after having negotiated or caused its financial and legal advisors to negotiate with Parent in good faith such proposed adjustments in the terms and conditions of this Agreement, the Company Board of Directors determines in its good faith judgment (after considering the advice of its financial advisor) to be as favorable to the Company’s stockholders as such Superior Proposal, and (iii) at least three full Business Days after the Company has provided the notice referred to in clause (i) above, the Company shall have delivered to Parent (A) a written notice of termination of this Agreement pursuant to this Section 4.03(e)

(f)                                   Nothing contained in this Agreement shall prohibit the Company or the Company’s Board of Directors from making any disclosure to the Company’s stockholders if, in the good faith judgment of the Company Board of Directors, after consultation with outside counsel to the Company, the failure to take such action would cause the Company’s Board of Directors to violate its fiduciary duties to the Company’s stockholders under applicable Law.

4.04                        Consents.  The Company shall use its commercially reasonable efforts to obtain all necessary consents, waivers and approvals of and deliver all required notices to any parties to any Contract listed in Section 2.03(f) of the Company Disclosure Schedules.

(a)                                 For six (6) years after the First Effective Time, Parent will and will cause the Surviving Company to fulfill and honor in all respects the obligations of the Company, in any case as in effect on the date of this Agreement, pursuant to the indemnification provisions of the Organizational Documents of the Company and pursuant to any indemnification agreements delivered to Parent prior to the First Effective Time, if any (collectively, the “Company Indemnification Provisions”) among the Company and the present and former directors and officers of the Company (the “D&O Indemnified Parties”).    In connection therewith, Parent shall advance expenses to the D&O Indemnified Parties as incurred to the fullest extent provided for under the Company Indemnification Provisions; provided, however, that the Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such person is not entitled to indemnification.  Parent shall ensure that the organizational documents of the Surviving Company shall contain indemnification provisions in favor of the D&O Indemnified Parties that are comparable in all material respects to those set forth in the Organizational Documents as in effect on the date of this Agreement.  Any claims for indemnification made under this Section 5.01 on or prior to the sixth (6th) anniversary of the First Effective Time shall survive such anniversary until the resolution thereof.

47

(b)                                 In connection with the Closing, the Company shall, at its own expense, purchase a directors’ and officers’ liability insurance or tail insurance policy on terms and conditions (including, without limitation, coverage limits) reasonably acceptable to Parent (the “D&O Tail”), that provides coverage for acts or omissions of the D&O Indemnified Parties occurring on or prior to the First Effective Time.  The premium for the D&O Tail shall be paid at the Closing, and Parent shall maintain such D&O Tail in effect for the full term thereof without any amendment or waiver of any provision therein that would adversely affect in any material respect the rights of the D&O Indemnified Parties.  Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to the Company or any of its subsidiaries for any of their respective directors, officers or other employees, it being understood and agreed that the indemnification provided for in this Section 5.01 is not prior to or in substitution for any such claims under such policies.

(c)                                  If Parent, the Surviving Company or any of its successors or assigns proposes to (i) consolidate with or merge into any other Person and Parent or the Surviving Company shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfer all or substantially all of its properties and assets to any Person, then, and in each case, proper provision shall be made prior to or concurrently with the consummation of such transaction so that the successors and assigns of Parent or the Surviving Company, as the case may be, shall, from and after the consummation of such transaction, honor the indemnification and other obligations set forth in this Section 5.01.

(d)                                 The Parties agree that all rights to exculpation, indemnification and advancement of expenses for acts or omissions occurring at or prior to the First Effective Time, whether asserted or claimed prior to, at or after the First Effective Time, now existing in favor of the current or former directors, officers or employees, as the case may be, of the Company and its subsidiaries as provided in their respective certificates of incorporation or by-laws or other organization documents or in any agreement shall survive the First Merger and shall continue in full force and effect.  The provisions of this Section 5.01 are intended to be in addition to the rights otherwise available to the current officers and directors of the Company and its subsidiaries by law, charter, statute, by-law or agreement, and shall operate for the benefit of, and shall be enforceable by, each of the D&O Indemnified Parties, their heirs and their representatives.  The obligations set forth in this Section 5.01 shall not be terminated, amended or otherwise modified in any manner that adversely affects any D&O Indemnified Parties, or any person who is a beneficiary under the policies referred to in this Section 5.01 and their heirs and representatives, without the prior written consent of such affected D&O Indemnified Party or other person.

(e)                                  The provisions of this Section 5.01 shall survive the consummation of the First Merger and Second Merger and the First Effective Time and Second Effective Time and (i) are intended to be for the benefit of, and shall be enforceable by, each D&O Indemnified Party, and his or her successors, heirs and Representatives and shall be binding on all successors and assigns of Parent and the Surviving Company and (ii) are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have by Contract or otherwise.  Parent and the Surviving Company shall pay all expenses, including reasonable attorneys’ fees and expenses, that may be incurred by a person in successfully enforcing such person’s rights provided in this Section 5.01.

5.02                        Efforts to Consummate.

(a)                                 Subject to the terms and conditions herein provided, from the date hereof until the earlier of the termination of this Agreement and the Closing Date, the Company shall use commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things reasonably

48

necessary, proper or advisable to consummate and make effective as promptly as practicable the transactions contemplated by this Agreement (including the satisfaction, but not waiver, of the Closing conditions set forth in Section 6.01).

(b)                                 Subject to the terms and conditions herein provided, from the date hereof until the earlier of the termination of this Agreement and the Closing Date, Parent, Merger Sub and Merger Sub II shall use commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things reasonably necessary, proper or advisable to consummate and make effective as promptly as practicable the transactions contemplated by this Agreement (including the satisfaction, but not waiver, of the Closing conditions set forth in Section 6.02).

5.03                        Notification.

(a)                                 From the date hereof until the earlier of the termination of this Agreement and the Closing Date, if the Company becomes aware of, or there occurs after the date of this Agreement, any fact or condition that constitutes a breach of any representation or warranty made by the Company in Article II or of any covenant that would cause the conditions set forth in Section 6.01(a) or Section 6.01(b), as applicable, not to be satisfied as of the Closing Date, the Company shall promptly disclose in writing to Parent such breach.

(b)                                 From the date hereof until the earlier of the termination of this Agreement and the Closing Date, if Parent becomes aware of, or there occurs after the date of this Agreement, any fact or condition that constitutes a breach of any representation or warranty made in Article III or any covenant that would cause the conditions set forth in Section 6.02(a) or Section 6.02(b), as applicable, not to be satisfied as of the Closing Date, Parent shall promptly disclose in writing to the Company such breach.

5.04                        Section 280G.  To the extent applicable payment rights are waived and 280G Waivers obtained or are otherwise not payable absent approval of the Stockholders, the Company shall promptly, but, in any event, no later than two (2) Business Days prior to the First Effective Time, submit for approval by the Stockholders by the requisite vote (and in a manner satisfactory to Parent), by such number of Stockholders as is required by the terms of Section 280G(b)(5)(B) of the Code, any payment and/or benefits that may, separately or in the aggregate, constitute a “parachute payment” within the meaning of Section 280G(b)(2) of the Code (“Section 280G Payments”) (which determination shall be made by the Company and shall be subject to review and approval by Parent), such that all such payments and benefits shall not be deemed to be Section 280G Payments (the “280G Approval”), and prior to the First Effective Time the Company shall deliver to Parent evidence satisfactory to Parent that a vote of Stockholders was solicited in conformance with Section 280G and the regulations promulgated thereunder and that (a) such requisite 280G Approval was obtained with respect to any Section 280G Payment, or (b) that the 280G Approval was not obtained with respect to any Section 280G Payment and as a consequence, that Section 280G Payment shall not be made or provided, pursuant to the waivers of those payments and/or benefits which were executed by the affected individuals prior to the vote of the Stockholders (the “280G Waivers”).  Prior to soliciting the 280G Approval, the Company shall use commercially reasonable efforts to obtain and deliver to Parent a 280G Waiver from each Person who the Company reasonably believes is, with respect to the Company, a “disqualified individual” (within the meaning of Section 280G of the Code) and who has received or could otherwise receive or have the right or entitlement to receive any Section 280G Payments.  Prior to obtaining the 280G Waivers described in the previous sentence, the Company shall provide, or cause to be provided, to Parent a draft of all solicitation and related documents (including any calculations of the Section 280G Payments) contemplated in this Section 5.04, including any disclosure documents.  The Company shall incorporate any reasonable comments into such documents that are made timely by Parent.

49

5.05                        Termination of Certain Company Benefit Plans.  Effective as of the Closing Date, the Company and any of its Subsidiaries shall terminate any and all group severance, separation or salary continuation plans, programs or arrangements and the Company Employee Benefit Plans identified on Section 5.05 of the Company Disclosure Schedule.  The Company shall provide Parent with evidence that such Company Employee Benefit Plans have been terminated (contingent upon the occurrence of and effective as of the Closing Date) pursuant to resolutions of the board of directors of the Company or such Subsidiary, as the case may be.  The form and substance of such resolutions shall be subject to review and approval of Parent.  For the avoidance of doubt, Parent or the Surviving Company shall be responsible for any compliance with COBRA, as applicable.

5.06                        Registration of Merger Shares, Severance Shares and New Debt Conversion Shares.

(a)                                 As promptly as practicable following the Closing Date (and in any event by not later than sixty (60) days following the Closing Date), Parent shall file with the SEC a Registration Statement under the Securities Act covering the resale of the Closing Merger Shares, the Severance Shares and the New Debt Conversion Shares (collectively, the “Initial Registration Shares”).  Parent shall use its reasonable best efforts to cause such Registration Statement filed under this Agreement to be declared effective as soon as reasonably practicable after filing and to maintain the continuous effectiveness of such Registration Statement until the earlier of (A) the date all such Initial Registration Shares have been sold pursuant to such Registration Statement, or (B) such time as all holders of such Initial Registration Shares may sell such Initial Registration Shares under Rule 144 of the Securities Act.  For purposes of this Section 5.06, Initial Registration Shares and Milestone Consideration Shares shall include any Parent Common Stock issued as a dividend or other distribution with respect to or in exchange for or in replacement of any such shares.

(b)                                 As promptly as practicable (and in any event within forty-five (45) days) following the issuance of any Milestone Consideration Shares under this Agreement, Parent shall file with the SEC, and use its reasonable best efforts to cause to be declared effective as soon as reasonably practicable after filing, either (i) a Registration Statement covering the resale of such Milestone Consideration Shares held by the Stockholders, or (ii) in the event Parent determines that it may register the resale of such Milestone Consideration Shares under an existing “shelf” Registration Statement, a prospectus supplement (a “Prospectus Supplement”) under such “shelf” Registration Statement covering the resale of such Milestone Consideration Shares.  Parent shall use its reasonable best efforts to maintain the continuous effectiveness of each Registration Statement or Prospectus Supplement, as applicable, until the earlier of (A) the date all such Milestone Consideration Shares have been sold pursuant to such Registration Statement or Prospectus Supplement, as applicable, or (B) such time as such time as all holders of such Milestone Consideration Shares may sell such Milestone Consideration Shares under Rule 144 of the Securities Act.

(c)                                  Parent shall use reasonable best efforts to comply with its obligations under the Securities Act and the Exchange Act to keep the Registration Statements or Prospectus Supplements referenced in clauses (a) and (b) effective through the dates referenced in clauses (a) and (b) and without limiting the foregoing, Parent shall (i) prepare and file with the SEC such amendments to such Registration Statements or Prospectus Supplements, as the case may be and amendments or supplements to the prospectus used in connection therewith as may be necessary to comply with the provisions of the Securities Act with respect to the sale or other disposition of all such Merger Shares included in such Registration Statements or Prospectus Supplements, as the case may be and (ii) register or qualify such Merger Shares included in such Registration Statements or Prospectus Supplements, as the case may be, under the applicable state securities or blue sky laws.  Parent shall also use reasonable best efforts to prevent the issuance of, or to secure the withdrawal of, any such stop order as promptly as practicable.  Parent shall notify the Stockholders

50

Representative, promptly after it shall receive notice thereof, of the date and time a Registration Statement and each post-effective amendment thereto shall have become or been declared effective or an amendment or supplement to any prospectus forming a part of the Registration Statement shall have been filed with the SEC.

(d)                                 Parent shall use commercially reasonable efforts to facilitate the resale of the Merger Shares under Rule 144 of the Securities Act when available to Stockholders, including (i) using commercially reasonable efforts to comply with its Exchange Act filing requirements, and (ii) upon receipt of representations reasonably acceptable to Parent’s counsel that such Stockholder meets the requirements for resale under Rule 144 of the Securities Act, obtaining a legal opinion from Parent’s counsel that such Merger Shares are eligible for resale under Rule 144 of the Securities Act and any legends or other restrictions on transfer of such shares may be removed.

(e)                                  Subject to the last sentence of Section 5.06(j), upon Parent’s request, each Stockholder shall furnish to Parent such information regarding such Stockholder, the Merger Shares held by such Stockholder and the offer and sale or other distribution proposed by such Stockholder as Parent may reasonably request, in connection with any registration of the Merger Shares and any resale of the Merger Shares under Rule 144 of the Securities Act. Parent shall have no liability hereunder to the extent any of the information supplied or to be supplied by a Stockholder expressly for inclusion or incorporation by reference in the Registration Statement, or Prospectus Supplement, as applicable, at the time the Registration Statement and each amendment or supplement thereto, if any, becomes effective under the Securities Act, contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading.

(f)                                   All costs, fees, and expenses incurred by Parent in connection with the preparation and filing of the Registration Statement and any amendments or supplements thereto, and any actions or filings necessary to maintain the effectiveness of the Registration Statement shall be at Parent’s expense, including all SEC fees, blue sky registration and filing fees, Nasdaq notices and filing fees, printing fees and expenses, transfer agents’ and registrars’ fees and expenses and all fees and expenses of Parent’s outside counsel and independent accountants; provided, however, that in no event shall Parent be required to pay any brokers’ fees or similar commissions on any sales of such shares by or on behalf of any Stockholders.

(g)                                  Parent may postpone the filing of any Registration Statement (or Prospectus Supplement) required hereunder for a reasonable period of time, not to exceed 180 days in the aggregate during any twelve month period, if in the good faith judgment of Parent following consultation with legal counsel, it would be detrimental to Parent or its stockholders for resales of Merger Shares to be made pursuant to any Registration Statement (or Prospectus Supplement) due to (i) the existence of a material development or potential material development involving Parent that Parent would be obligated to disclose or incorporate by reference in such Registration Statement (or Prospectus Supplement), which disclosure would be premature or otherwise inadvisable at such time or (ii) interference with an actual or potential material financing or business combination transaction involving Parent (a “Black Out Period”).  Upon notice of the existence of a Black Out Period from Parent to any Stockholders with respect to any Registration Statement (or Prospectus Supplement), such Stockholder shall refrain from selling its Merger Shares under such Registration Statement (or Prospectus Supplement) until such Black Out Period has ended.  There shall be no more than an aggregate of one hundred eighty (180) days of Black Out Period in any twelve (12) month period. In addition, Parent may postpone the filing of any Registration Statement (or Prospectus Supplement) required hereunder to the extent that such filing would occur during the period (A) beginning on February 11 of any given calendar year and (B) ending on the date that is three (3) Business Days after the date Parent files its audited financial statements on Form 10-K for the then most recently completed fiscal year.

51

(h)                                 Parent shall indemnify and hold harmless, to the extent permitted by applicable Law, the Stockholders, from and against any Losses to which any Stockholders may become subject (under the Securities Act or otherwise) to the extent such Losses arise out of, directly or indirectly, any untrue statement of a material fact contained in the Registration Statement or any other document filed in accordance with this Section 5.06, or any omission to state therein a fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that Parent will not be liable in any such case to the extent that any such Losses arising out of, directly or indirectly, any untrue statement or omission, made in reliance upon and in conformity with information furnished to Parent by or on behalf of any Stockholders specifically for use in the preparation of the Registration Statement.  Each Stockholder, on a several basis, shall indemnify and hold harmless, to the extent permitted by applicable Laws, Parent to the same extent as the foregoing indemnity from Parent, but only with reference to information furnished in writing by or on behalf of such Stockholder to Parent, specifically for use in the preparation of the Registration Statement.  Sections 7.04 and 7.05 shall apply, mutatis mutandis, to any claim for indemnification under this Section 5.06(h).

(i)                                     Notwithstanding anything contained in this Agreement to the contrary, Parent shall not be obligated to take any action under this Section 5.06 unless and until the following conditions shall have been met: (i) Parent shall have received any audited financial statements of Company and any other financial information of Company required for inclusion in the Registration Statement (or Prospectus Supplement) as reasonably determined by Parent, (ii) Parent shall have received all information it reasonably needs to prepare pro forma financial statements if required to be included in the Registration Statement (or Prospectus Supplement) under SEC rules, and (iii) Parent shall have received such auditor consents from its and the Company’s auditors as it reasonably deems necessary or desirable.  Parent shall use commercially reasonable best efforts, acting in good faith, to cause such conditions to be satisfied. If a Stockholder fails to furnish to Parent the information regarding such Stockholder as is necessary for inclusion in the Registration Statement within thirty (30) days of Stockholder’s receipt of Parent’s written request (including any such information requested in accordance with Section 5.06(e)), the Merger Shares held by such Stockholder and the offer and sale or other distribution proposed by such Stockholder as Parent may reasonably request, the Parent is not required to include any such Stockholder’s Merger Shares in the Registration Statement.

5.07                        Provision of Financial Statements.

(a)                                 Prior to the Closing, the Company shall deliver to Parent such financial statements of the Company as Parent shall reasonably request in order to enable Parent to comply with its reporting obligations under the Exchange Act (including its obligation to file with the SEC a Current Report on Form 8-K containing all information required by Items 2 and 9 of the SEC’s Form 8-K (without regard to the time period in which such information must be filed)), together with executed reports of the outside auditors with respect to all such financial statements that have been audited.  Such reports shall be in form and substance reasonably satisfactory to Parent.  The financial statements delivered pursuant to this Section 5.07 shall be prepared in accordance with GAAP and shall conform to all provisions of the SEC’s Regulation S-X, such that such financial statements are suitable for filing by Parent with the SEC in response to Items 2 and 9 of the SEC’s Current Report on Form 8-K.  The Company shall cause such outside auditors to deliver to Parent executed consents, in form and substance reasonably satisfactory to Parent and suitable for filing by Parent with the SEC, which consents shall authorize Parent to file with the SEC the reports referred to in this Section 5.07 and all other reports delivered by the Company hereunder; provided, however, that Parent must provide Company a final Form 8-K at least five (5) Business Days prior to the proposed filing date so it can be provided to its auditors to obtain the requested consent.

52

(b)                                 On or prior to November 9, 2016, the Company shall deliver to Parent unaudited consolidated balance sheet as of September 30, 2016 and the related consolidated statements of operations and comprehensive loss, consolidated statements of changes in convertible preferred stock and stockholders’ deficit and consolidated statements of cash flows for the nine (9) month period then ended, certified by the chief financial officer of the Company (solely in his or her capacity as such) as, to the knowledge and belief of such chief financial officer, complete and correct in all material respects, subject to year-end adjustments and lack of footnotes, as of the Closing Date; provided that such certificate shall not be deemed inaccurate or incorrect to the extent such inaccuracy or error arises out of or is related to any adjustments in such financial statement required by Parent to the extent not required by GAAP.

5.08                        Certain Employee Matters. Subject to the execution of a general release of claims in form and substance reasonably satisfactory to Parent within 21 days after presentation thereof (or such longer period as may be required by law), Parent shall offer each Employee (other than an Employee who is party to an Employee Agreement that provides for severance) terminated by Parent on, or within sixty (60) days following, the Closing Date, (i) that does not receive a transaction completion bonus granted by the Company prior to Closing (those persons who are receiving such transaction completion bonuses are set forth on Section 5.08(i) of the Company Disclosure Schedule) in connection with the Closing of the transactions contemplated by this Agreement two (2) months of severance payments at the rate such Employee is being paid on the date hereof as set forth on Section 2.13(a)(i) of the Company Disclosure Schedules (payable in accordance with Parent’s customary payroll practices commencing on the next regular payroll date following the effectiveness of the release), (ii) reimbursement for continuation of medical coverage in accordance with the provisions of COBRA at active employee rates under the applicable plan for two (2) months following the termination of the medical coverage in accordance with the terms of the applicable medical plan, subject to the applicable Employee’s timely election of continuation coverage and continued eligibility to receive COBRA coverage, and the terms and conditions of the Parent’s medical plan (the “Health Benefits”); provided, that such Health Benefits shall immediately cease as of the date the applicable Employee becomes eligible for coverage under the group medical plan of a new employer and (iii) a cash payout equal to such Employee’s accrued but unpaid vacation time at such Employee’s salary rate on the date hereof as set forth on Section 2.13(a)(i) of the Company Disclosure Schedules (payable in a lump sum on the next regular payroll date following the termination of employment, unless sooner required by law and, for the avoidance of doubt, the receipt of the amounts under this clause (iii) are not subject to execution of the release). Parent may modify its obligation to provide the Health Benefits if required by applicable law and/or to avoid any penalty or excise taxes imposed on it (or the Employee) in connection with the continued payment of premiums by the Company under the Code or the Patient Protection and Affordable Care Act of 2010, as amended, each as determined by Parent in its good faith reasonable discretion; provided that Parent will use reasonable commercial efforts to cause such modifications not to result in an increase in cost to the affected employee to acquire equivalent Health Benefits.

ARTICLE VII

INDEMNIFICATION

7.01                        Survival of Representations, Warranties, Covenants, Agreements and Other Provisions.

(a)                                 The representations and warranties of the Company contained in this Agreement or any other certificate or instrument delivered pursuant to this Agreement shall survive the Closing and shall terminate on the date which is eighteen (18) months after the Closing Date (the “Survival Date”); provided, however, that the Fundamental Representations (other than the Specified Intellectual Property Representations and the representations and warranties in Section 2.08 (Tax Matters)) shall survive the Closing and shall terminate upon the expiration of the applicable statute of limitations; provided further, however that (i) the Specified Intellectual Property Representations shall survive the Closing and shall terminate on the date which is five (5) years after the Closing Date and (ii) the representations and warranties in Section 2.08 (Tax Matters) shall survive the Closing and shall terminate upon the thirtieth (30th) day after the expiration of the applicable statute of limitations.   No claim for indemnification hereunder for breach of any such representations and warranties may be made after the expiration of such survival period; provided, however, that all representations and warranties of the Company contained in this Agreement or any other certificate or

57

instrument delivered pursuant to this Agreement shall survive beyond the survival periods specified above with respect to any inaccuracy therein or breach thereof if a claim is made hereunder prior to the expiration of the survival period for such representation and warranty, in which case such representation and warranty shall survive as to such claim until such claim has been finally resolved.

(b)                                 The agreements, covenants and other obligations of the Parties hereto shall survive the Closing and the First Effective Time in accordance with their terms.

7.02                        Indemnification by the Stockholders.                                       After the Closing, subject to the terms and conditions of this Article VII, the Company Indemnifying Parties, severally and not jointly, to the extent of a Company Indemnifying Party’s respective interest in the Milestone Consideration not yet paid to the Exchange Agent for the benefit of the Stockholders (but not against Milestone Consideration for which payment to the Exchange Agent for the benefit of the Stockholders is past due), solely by set-off pursuant to Section 7.06 against the Milestone Consideration, will indemnify and hold harmless Parent from and against, whether or not involving a third party claim, all Losses incurred by Parent, directly or indirectly, relating to or arising from (a) any breach or inaccuracy of any representation or warranty of the Company in Article II of this Agreement, (b) any Indemnified Tax, (c) any payments required to be made to any stockholder of the Company with respect to any claims arising from or with respect to the allocation or distribution of Merger Consideration following Parent’s payment to the Exchange Agent of the correct aggregate amount of Merger Consideration (collectively, the “Consideration Spreadsheet Losses”), (d) any payments made by the Surviving Company or Parent pursuant to any continuing obligation to indemnify any officer or director of the Company for actions taken, or omissions made, prior to the Closing Date or (e) any payments required to be made to any stockholder of the Company with respect to such stockholder’s appraisal rights under the DGCL (“Appraisal Rights Payments”) solely to the extent such payments are in excess of the Merger Consideration that such stockholder would otherwise have received and all reasonable costs and expenses incurred by the Surviving Company or Parent in connection with any Actions or settlements in connection therewith, provided, however, that if Parent settles any such Actions without the Stockholders Representative’s consent, then the cost of such settlement shall not be recoverable under this Article VII. Notwithstanding any provision herein to the contrary, Parent shall not be entitled to indemnification with respect to any Losses arising directly or indirectly from any post-Closing (i) acts or omissions by Parent or the Surviving Company which result in a change of facts or circumstances from the facts and circumstances underlying the Company’s representations and warranties contained in Article II hereof, when such representations and warranties were made or deemed made; or (ii) changes in Law.  Under no circumstances shall Parent be entitled to be indemnified hereunder for any punitive, exemplary, incidental or consequential damages.  Notwithstanding anything contained in this Agreement to the contrary, the Parent shall not have any right to indemnification as a result of a breach of a representation or warranty set forth in Section 2.08 (other than Sections 2.08(g), (h), (i), (k), (l), (o), and (p)) from and against any and all Taxes (or non-payment thereof) occurring in or related to periods after the Closing; provided, however, that (x) the preceding limitation shall not apply with respect to any indemnification obligation that arises hereunder without regard to Section 2.08 (e.g., indemnification for Indemnified Taxes), even if such obligation also arises in respect of a breach of a representation or warranty set forth in Section 2.08 and (y) for these purposes, penalties and interest attributable to a Tax attributable to a Pre-Closing Tax Period or attributable to a failure to comply with a requirement relating to the preparation or filing of any Tax Return filed or required to be filed before the Closing Date shall not be treated as a Tax of any of the Company or Company Subsidiaries for any taxable periods (or portions thereof) beginning after the Closing Date.

58

7.03                        Limitations on Indemnification.

(a)                                 Parent will not be entitled to be indemnified for Losses with respect to the matters described in Section 7.02 for any Loss except to the extent the total of all Losses with respect to such matters, in the aggregate, exceeds $400,000 (the “Basket”), at which time Parent shall have the right to set-off only the full amount of such Losses (i.e., and not just the excess over the Basket) in excess of the Basket against the Milestone Consideration in compliance with Section 7.06 in the order such Milestone Consideration becomes due, until the full amount of Parent’s indemnifiable Losses shall have been so set-off against the Milestone Consideration in compliance with Section 7.06.  Notwithstanding the foregoing, Appraisal Rights Payments shall not be subject to or counted towards such Basket and may be set-off against the Milestone Consideration in compliance with Section 7.06.    Notwithstanding anything to the contrary herein, the maximum amount of Losses that may be set-off against and reduce the Milestone Consideration pursuant to this Article VII is limited to $5,000,000 (the “Indemnity Cap”).  For the avoidance of doubt, in no event shall any Losses or other amounts be set-off against or reduce the Merger Consideration pursuant to this Article VII (individually or together with all previous amounts that were set-off against or reduced the Milestone Consideration) by an aggregate amount in excess of the Indemnity Cap.  Notwithstanding the foregoing, neither the Basket nor the Indemnity Cap shall apply to any Losses resulting from (1) fraud, (2) any breach of the Fundamental Representations, (3) the adjustments set forth in Section 1.13 with respect to Closing Cash and Estimated Closing Cash, (4) Indemnified Taxes or (5) Consideration Spreadsheet Losses.

(b)                                 In addition to the foregoing limits, except in the case of fraud, Parent acknowledges that, from and after the Closing, the sole and exclusive remedy of Parent with respect to claims for indemnifiable Losses pursuant to this Article VII shall be to set-off the amount of such Losses (subject to the Indemnity Cap, if applicable) against the Milestone Consideration not yet paid to the Exchange Agent for the benefit of the Stockholders (but not against Milestone Consideration for which payment to the Exchange Agent for further distribution to the applicable Stockholders is past due), in the order in which such Milestone Consideration becomes due, all in compliance with Section 7.06. Except in the case of fraud, no amount previously paid or delivered by the Parent or Surviving Company hereunder shall be subject to recovery by Parent, Merger Sub, Merger Sub II, Surviving Company, any Affiliate of Parent or Merger Sub or Merger Sub II or Surviving Company, or any Person claiming by or through Parent, Merger Sub, Merger Sub II, Surviving Company or any Affiliate of Parent or Merger Sub or Merger Sub II or Surviving Company.

(c)                                  Parent shall take, and cause its Affiliates to take, all commercially reasonable steps to mitigate any Loss upon becoming aware of any event or circumstance that would be reasonably expected to, or does, give rise thereto. Notwithstanding anything contained herein to the contrary, the amount of Losses subject to indemnification under this Article VII shall be calculated after giving effect to (i) any insurance proceeds actually received by Parent (or any of its Affiliates) with respect to such Losses, less costs incurred to obtain such insurance proceeds, (ii) any recoveries which are obtained by Parent (or any of its Affiliates) from any other third party, less costs to obtain such recoveries, or (iii) any Tax refunds or actual reductions in Taxes realized by Parent in the tax year in which the Loss was incurred or in the immediately succeeding tax year as a result of incurring such Loss.

(d)                                 The right of Parent to recover for indemnifiable Losses pursuant to this Article VII shall not be affected by any investigation conducted or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or inaccuracy of or compliance with any representation, warranty, covenant or obligation of Company herein.

(e)                                  For purposes of determining the amount of Losses subject to indemnification under this Article VII, but not for determining whether a breach of any representation or warranty has occurred, the

59

representations and warranties of the Parties in this Agreement shall not be deemed to be qualified by any references to materiality or Material Adverse Effect.

7.04                        Indemnification Procedures.

(a)                                 All claims for indemnification by Parent under this Article VII shall be brought in good faith and asserted and resolved in accordance with this Section 7.04 and be subject to the limitations set forth elsewhere in this Article VII.

(b)                                 If Parent intends to seek indemnification pursuant to this Article VII, Parent shall promptly notify the Stockholders Representative in writing of such claim, describing such claim in reasonable detail and the amount or estimated amount of such Losses (the “Claims Notice”); provided that, subject to the limitations in respect of the Survival Date, the failure of Parent to promptly notify the Stockholders Representative shall not relieve the Company Indemnifying Parties from liability for such claims except and only to the extent that the Company Indemnifying Parties were actually prejudiced by such delay.  In the event that Parent delivers a Claim Notice, Parent shall promptly provide, and shall cause Surviving Company to promptly provide, the Stockholders Representative with (x) all books, records and other materials and information reasonably requested by the Stockholders Representative related to the claims set forth in the Claims Notice, and (y) the right to speak to, ask questions of and receive responsive answers from key personnel of Parent and Surviving Company having responsibility for or knowledge of the matters set forth in the Claims Notice.

(c)                                  For a period of thirty (30) Business Days after receipt of a Claims Notice (the “Dispute Period”) in compliance with Section 7.04(a), Parent shall make no reduction to the Milestone Consideration with respect to the Losses alleged in such Claims Notice unless Parent shall have received written authorization from the Stockholders Representative to make such reduction. After the expiration of the Dispute Period, Parent shall reduce the Milestone Consideration by an amount equal to all or a portion of the Losses set forth in such Claims Notice only to the extent the Stockholders Representative has not objected in a written statement to the applicable portion of any claim or claims made in the Claims Notice, which written statement shall include in reasonable detail the basis for such objection, and such written statement shall have been delivered to Parent prior to the expiration of the Dispute Period.  Parent shall not set-off against or reduce the Milestone Consideration by the amount of any claimed Losses that are timely objected to by the Stockholders Representative.

(d)                                 If the Stockholders Representative objects in writing to any portion of the claim or claims by Parent made in any Claims Notice within the Dispute Period, Parent and the Stockholders Representative shall negotiate in good faith for forty-five (45) days after Parent’s receipt of such written objection (the “Negotiation Period”) to resolve such objection. If Parent and the Stockholders Representative shall so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties.  Parent shall be entitled to conclusively rely on any such memorandum and Parent shall reduce the Milestone Consideration in accordance with the terms of such memorandum.

(e)                                  If no such agreement can be reached during the Negotiation Period, but in any event upon the expiration of the Negotiation Period, either Parent or the Stockholders Representative may bring suit in a court having competent jurisdiction.  The final non-appealable decision of a court of competent jurisdiction as to the validity and amount of any claim in such Claims Notice shall be binding and conclusive upon the Parties to this Agreement.  Judgment upon any award rendered by the court may be entered in any other court having jurisdiction over the applicable Party.

60

7.05                        Third Party Claims

(a)                                 If any claim, action, suit or proceeding is made against Parent or the Surviving Company by a third party that will or could be the subject of a Claims Notice (a “Third Party Claim”), Parent shall give prompt written notice of such Third Party Claim to the Stockholders Representative.  The Stockholders Representative shall be entitled to participate in the defense thereof and to employ counsel, at the sole expense of the Stockholders, separate from the counsel employed by Parent.

(b)                                 Neither Parent nor Company shall consent to entry of a judgment, admit any liability with respect to, or settle, compromise or discharge, a Third Party Claim without the Stockholders Representative’s prior written consent, not to be unreasonably delayed or withheld.

(c)                                  Subject to Section 7.05(b), Parent and the Company shall prosecute, defend and settle any Third Party Claim.  Parent and the Company shall pursue, through counsel of their selection, the prosecution, defense or settlement of all Third Party Claims until such time, if any, that Parent shall elect not to pursue indemnification with respect to such Third Party Claim.  Parent agrees to, and to cause the Company to, act reasonably and in good faith in connection with the prosecution, defense or settlement of any Third Party Claim. The Company Indemnifying Parties will remain responsible for any Losses of Parent and the Company as a result of such Third Party Claims to the extent subject to indemnification under this Article VII, and Parent and the Company shall retain all remedies to which they are entitled under this Article VII.  Parent shall keep the Stockholders Representative reasonably informed of all material developments with respect thereto and shall allow the Stockholders Representative to participate in the prosecution, defense and settlement of such Third-Party Claim at the expense of the Stockholders.

7.06                        Set-off Right.  Subject to and after compliance with Sections 7.03, 7.04 and 7.05 herein, Parent shall have the right to set-off the amount of indemnifiable Losses pursuant to this Article VII (subject to the Indemnity Cap, if applicable) against the Milestone Consideration not yet paid to the Exchange Agent for further distribution to the Stockholders (but not against Milestone Consideration for which payment to the Exchange Agent for further distribution to the Stockholders is past due), in the order in which such Milestone Consideration becomes due,  in order to provide recourse to Parent with respect to Parent’s rights under this Agreement, including Parent’s indemnification rights under this Article VII.

7.07                        Sole and Exclusive Remedy.  From and after the Closing, this Article VII will provide Parent’s and Surviving Company’s sole and exclusive recourse and remedy for disputes, claims and Losses relating to or arising, directly or indirectly, from this Agreement and the transactions contemplated hereby, other than for fraud. This Article VII will not affect any remedy Parent may have under this Agreement prior to the Closing or upon termination of this Agreement prior to a Closing.

7.08                        Tax Treatment.  Any payment under this Article VII shall be treated by the parties for U.S. federal, state, local and non-U.S. income Tax purposes as a purchase price adjustment unless otherwise required by applicable Law.

61

ARTICLE VIII

TAX MATTERS

8.01                        Straddle Period

In the case of any Straddle Period, the amount of any income Taxes for the Pre-Closing Tax Period shall be determined based on an interim closing of the books as of the close of business on the Closing Date (and for such purpose, the taxable period of any partnership or other pass-through entity in which the Company or any of its Subsidiaries holds a beneficial interest shall be deemed to terminate at such time).  Any Property Taxes for any Straddle Period shall be allocated to the portion of the Straddle Period ending on the Closing Date on a per diem basis, and all other Taxes for any Straddle Period shall be allocated as if such Straddle Period ended on the Closing Date, except that exemptions, allowances or deductions that are calculated on an annual basis (including depreciation and amortization deductions), other than with respect to property placed in service after the Closing, shall be allocated on a per diem basis.

8.02                        Cooperation on Tax Matters

(a)                                 Parent, Surviving Company, Subsidiaries, the Stockholders Representative, and the Stockholders shall cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the filing of Tax Returns pursuant to this ARTICLE XIII and any audit, litigation or other proceeding with respect to Taxes.  Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information that are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.  Surviving Company, Stockholders Representative, the Subsidiaries and Stockholders agree (A) to retain all books and records with respect to Tax matters pertinent to Company and its Subsidiaries relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by Parent or the Stockholders Representative, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (B) to give the other Party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other Party so requests, Parent or Stockholders Representative, as the case may be, shall allow the other Party to take possession of such books and records.

(b)                                 Parent and the Stockholders Representative further agree, upon request, to use their commercially reasonable best efforts to obtain any certificate or other document from any governmental authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby).

8.03                        Transfer Taxes

All transfer, documentary, sales, use, stamp, registration and other such Taxes, and all conveyance fees, recording charges and other fees and charges (including any penalties and interest) incurred in connection with the consummation of the transactions contemplated by this Agreement shall be borne fifty percent (50%) by Parent and fifty percent (50%) by Stockholders.

8.04                        Certain Tax Covenants.

(a)                                 Parent shall prepare, or cause to be prepared, all Tax Returns of the Company and its Subsidiaries that are filed after the Closing Date.  All such Tax Returns shall be prepared in accordance with the Company’s and its Subsidiaries’ past practice, except as otherwise required by applicable Law.  Parent shall provide a copy of each such Tax Return relating to a period (or portion thereof) before the Closing Date to the Stockholders Representative as soon as reasonably practicable (and in any event at least twenty-five (25) calendar days) before the deadline for filing each such Tax Return and shall make all changes to such

62

Tax Returns reasonably requested by the Stockholders Representative if received by Parent at least five days prior to the deadline for filing each such Tax Return within such twenty day period.

(b)                                 Following the Mergers, neither Parent nor the Surviving Company will (and neither Parent nor the Surviving Company will allow any of its Affiliates to) (i) amend or modify a Tax Return of the Company or any of its Subsidiaries for any Pre-Closing Tax Period, (ii) take any action that would extend the applicable statute of limitations for any Taxes or Tax Return of the Company or any of its Subsidiaries for any Pre-Closing Tax Period, (iii) file, amend or revoke any Tax election of the Company or any of its Subsidiaries for a Pre-Closing Tax Period, (iv) make a voluntary disclosure to a Governmental Entity with respect to any Tax or Tax Return of the Company or any of its Subsidiaries for any Pre-Closing Tax Period, or (v) file an election under Section 338(g) of the Code with respect to the acquisition of Company Stock pursuant to the Mergers, in each case, without the prior written consent of the Stockholders Representative (such consent not be unreasonably withheld, conditioned or delayed), if any such action would result in any obligation of the Company Indemnifying Parties to indemnify Parent under this Agreement.  None of Parent, Company,  Merger Sub II (including, for the avoidance of doubt, the Surviving Company) will, and none of Parent, Company, Merger Sub II (including, for the avoidance of doubt, the Surviving Company) will allow any of its Affiliates to, take any action on the Closing Date after the First Effective Time, other than an action in the ordinary course of business or expressly contemplated by this Agreement, which would result in any Tax liability to the Stockholders or any indemnity for Taxes under this Agreement.

ARTICLE IX

9.01                        Termination.  This Agreement may be terminated at any time prior to the Closing:

(a)                                 by the mutual written consent of Parent and the Company;

(b)                                 by Parent, if any of the representations or warranties of the Company set forth in Article II shall not be true and correct, or if the Company has failed to perform any covenant or agreement on the part of the Company set forth in this Agreement (including an obligation to consummate the Closing), such that the conditions to Closing set forth in either Section 6.01(a) or Section 6.01(b) would not be satisfied as of the Closing Date and the breach or breaches causing such representations or warranties not to be true and correct, or the failures to perform any covenant or agreement, as applicable, are not cured within fifteen (15) Business Days after written notice thereof is delivered to the Company; provided, however, that Parent and/or Merger Sub is not then in breach of this Agreement so as to cause the condition to Closing set forth in either Section 6.02(a) or Section 6.02(b) to not be satisfied as of the Closing Date;

(c)                                  by the Company, if any of the representations or warranties of Parent or Merger Sub set forth in Article III shall not be true and correct, or if Parent or Merger Sub has failed to perform any covenant or agreement on the part of Parent or Merger Sub, respectively, set forth in this Agreement (including an obligation to consummate the Closing), such that the conditions to Closing set forth in either Section 6.02(a) or Section 6.02(b) would not be satisfied as of the Closing Date and the breach or breaches causing such representations or warranties not to be true and correct, or the failures to perform any covenant or agreement, as applicable, are not cured within fifteen (15) Business Days after written notice thereof is delivered to Parent or Merger Sub; provided, however, that the Company is not then in breach of this

63

Agreement so as to cause the condition to Closing set forth in Section 6.01(a) or Section 6.01(b) from being satisfied as of the Closing Date;

(d)                                 by Parent or the Company, if the transactions contemplated by this Agreement shall not have been consummated on or prior to the date that is six (6) months from the Effective Date (such date, the “Outside Date”) and the Party seeking to terminate this Agreement pursuant to this Section 9.01(d) shall not have (provided, however, that if such Party is Parent, neither Parent nor Merger Sub shall have) breached in any material respect its obligations under this Agreement in any manner that shall have been the principal cause of the failure to consummate the transactions contemplated by this Agreement on or before the Outside Date;

(e)                                  by Parent or the Company, if any Governmental Entity shall have enacted, issued, promulgated, enforced or entered, or threatens to enact, issue, promulgate, enforce or enter any statute, rule, regulation, executive order, decree, injunction, order or other legal restraint which is in effect and which has the effect of making the Mergers illegal;

(f)                                   by Company, prior to the adoption of this Agreement by the Stockholder Consent, in accordance with, and subject to the terms and conditions of, Section 4.03(e); or

(g)                                  by Parent, if Estimated Closing Cash is less than negative six million dollars (-$6,000,000).

9.02                        Effect of Termination.  In the event this Agreement is terminated by either Parent or the Company as provided above, the provisions of this Agreement shall immediately become void and of no further force and effect (other than this Section 9.02, Section 10.01(d), Section 10.01(e) and Article XII hereof which shall survive the termination of this Agreement), and there shall be no liability on the part of either Parent, Merger Sub, Merger Sub II, the Company, the Stockholders Representative or the Stockholders to one another, except for willful breaches of this Agreement prior to the time of such termination; provided, however, that if the Company terminated this Agreement pursuant to Section 9.01(f), then, no later than the next Business Day following the date of such termination, the Company shall pay to Parent, as Parent’s sole and exclusive remedy, the Termination Fee by wire transfer of immediately available funds to an account designated by Parent, pursuant to Section 4.03.  Each of the Company, Parent, Merger Sub and Merger Sub II acknowledges that the agreements contained in this Section 9.02 are an integral part of the transactions contemplated by this Agreement, that without these agreements the Company, Parent, Merger Sub and Merger Sub II would not have entered into this Agreement, and that any amounts payable pursuant to this Section 9.02 do not constitute a penalty.

12.13                             Counterparts.  This Agreement may be executed in multiple counterparts, any one of which need not contain the signature of more than one (1) Party, but all such counterparts taken together shall constitute one and the same instrument.

12.14                             Governing Law.  All issues and questions concerning the construction, validity, interpretation and enforceability of this Agreement and the Exhibits and Schedules hereto shall be governed by, and construed in accordance with, the Laws of the State of Delaware, without giving effect to any choice of Law or conflict of Law rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware.

85

12.15                             Jurisdiction.  Any Action seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby shall be brought and determined exclusively by the Court of Chancery of the State of Delaware; provided, however, that if the Court of Chancery of the State of Delaware does not have jurisdiction, any such Action shall be brought exclusively in the United States District Court for the District of Delaware or any other court of the State of Delaware, and each of the Parties hereby consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such Action and irrevocably waives, to the fullest extent permitted by Law, any objection which it may now or hereafter have to the laying of the venue of any such Action in any such court or that any such Action which is brought in any such court has been brought in an inconvenient forum.  Process in any such Action may be served on any Party anywhere in the world, whether within or without the jurisdiction of any such court.  Without limiting the foregoing, each Party agrees that service of process on such Party as provided in Section 12.03 shall be deemed effective service of process on such Party.

12.16                             Remedies Cumulative.  Except as otherwise provided herein, any and all remedies herein expressly conferred upon a Party shall be deemed cumulative with, and not exclusive of, any other remedy conferred hereby, or by Law or equity upon such Party, and the exercise by a Party of any one remedy shall not preclude the exercise of any other remedy.

12.17                             Specific Performance.  Each of the Parties acknowledges that the rights of each Party to consummate the transactions contemplated hereby are unique and recognizes and affirms that in the event of a breach of this Agreement by any Party, money damages may be inadequate and the non-breaching Party may have no adequate remedy at Law.  Accordingly, the Parties agree that prior to a valid termination of this Agreement in accordance with this Agreement, such non-breaching Party shall have the right, in addition to any other rights and remedies existing in its favor at Law or in equity, to enforce its rights and the other Party’s obligations hereunder not only by an Action or Actions for damages but also by an Action or Actions for specific performance, injunctive and/or other equitable relief (without posting of bond or other security).  Each of the Parties hereby waives any requirement under Law to post a bond, undertaking or other security as a prerequisite to obtaining equitable relief.

The Company hereby acknowledges, on behalf of itself and its affiliates, that it has had an opportunity to ask for and has obtained information relevant to such representation, including disclosure of the reasonably foreseeable adverse consequences of such representation, and it hereby waives any conflict arising out of such future representation.  Without limiting the foregoing, the Parties agree that they do not intend for the attorney-client privilege between the Firm and the Company to continue with the Company following the Closing.  Accordingly, none of Parent, the Company, Merger Sub, Merger Sub II or the Surviving Company shall have any rights with respect to the attorney-client privilege that existed between the Firm and the Company prior to the Closing and each of the Parent, the Company, Merger Sub, Merger Sub II or the Surviving Company agree not to waive or seek to waive such privilege or otherwise obtain, or seek to obtain, any information subject to attorney-client privilege with respect to any time period prior to the First Effective Time.
