Each holder of Dissenting Shares who is entitled to exercise the rights granted by Section 1300 of the California Code pursuant to the immediately preceding sentence and who becomes entitled to payment for such shares pursuant to Section 1303 of the California Code shall receive payment therefor from the Surviving Corporation in accordance with the California Code; provided, however, that (i) if any such holder of Dissenting Shares shall have failed to establish such holder’s entitlement to appraisal rights as provided in Sections 1301 and 1302 of the California Code, or (ii) if any such holder of Dissenting Shares shall have effectively withdrawn such holder’s demand for appraisal of such shares or lost such holder’s right to appraisal and payment for such holder’s shares under Sections 1304 or 1309 of the California Code, such holder shall forfeit the right to appraisal of such shares and each such share shall not constitute a Dissenting Share and shall be treated in the same manner as a share of Common Stock that was not a Dissenting Share and converted, as of the Effective Time, into a right to receive from the Surviving Corporation the consideration deliverable in respect of a share of Common Stock, as determined in accordance with Section 2.7(b), without any interest

(f)    Stock of Merger Sub. Each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into one (1) validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation and all such shares together shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

Until so surrendered, outstanding Certificates (other than

those representing Dissenting Shares, unless the holder thereof loses its right to appraisal) will be deemed from and after the Effective Time, for all corporate purposes, to evidence the right to receive the Merger Consideration into which such securities shall have been so converted. Each Optionholder shall have delivered to the Company an executed Optionholder Consent Agreement as of the Closing, as required by Section 2.7(d) and each holder of Restricted Stock shall have delivered to the Company an executed Letter of Transmittal as required by Section 2.7(c).
(ii)    At the Effective Time, and by virtue of the operation of Section 8.2(a), each Company Equityholder shall be deemed to have contributed an amount to the Escrow Fund equal to the product of (x) the total number of shares of Common Stock held by such Company Equityholder immediately prior to the Effective Time plus the total number of shares of Common Stock underlying any Company Options held by such Company Equityholder immediately prior to the Effective Time, multiplied by (y) the Escrow Per Share Payment Amount.
(iii)    At the Effective Time, and by virtue of the operation of Section 8.2(b), each Company Equityholder shall be deemed to have contributed an amount to the Shareholders’ Representative Expense Fund equal to the product of (x) the total number of shares of Common Stock held by such Company Equityholder immediately prior to the Effective Time plus the total number of shares of Common Stock underlying any Company Options held by such Company Equityholder immediately prior to the Effective Time, multiplied by (y) the Shareholders’ Representative Expense Fund Per Share Payment Amount.

2.9    Milestone Payment Amount.
(a)    Definitions Related to Milestones.
(i)    Antibody” means any antibody, including conventional and novel formats thereof (including multi-specific formats), or fragment thereof, all of the foregoing whether naturally occurring, artificially produced, raised in an artificial system or created through modification of an antibody produced in any of the foregoing ways or otherwise.

-16-





(ii)    Derivative” means, with respect to any given Antibody (including any Antibody fragment), all derivatives, fragments, and modified forms or versions of such Antibody, including each of the following: (a) any heavy chain, light chain, subunit, or fragment of such Antibody or fragment thereof (which heavy chain, light chain, subunit, or fragment may include amino acid or nucleic acid substitutions relative to the original heavy chain, light chain, subunit, or fragment); (b) any Antibody or fragment thereof containing any of the foregoing; and (c) any chemically modified version of any of the foregoing. Without limiting the generality of the foregoing: (x) all humanized versions of a given Antibody or Antibody fragment are Derivatives of that Antibody or Antibody fragment; (y) linking such Antibody or Antibody fragment to a toxin or other active pharmaceutical ingredient produces a Derivative of such Antibody or Antibody fragment (even if one (1) or more nucleic acid or amino acid substitutions are introduced in connection with such linkage or otherwise); and (z) all antibodies or antibody fragments containing one or more of the CDRs of such Antibody or Antibody fragment are Derivatives of such Antibody or Antibody fragment, including multi-specific antibodies that also include specificities originating with a different Antibody or Antibody fragment. For purposes of this definition, “CDR” means a complementarity determining region of an antibody.
(iii)    Fixed Light Chain Chicken” means a genetically engineered chicken or progeny of a genetically engineered chicken in which the antibody genes are such that the same light chain V region amino acid sequence is used in the majority of antibodies that such chicken produces.
(iv)    HuMab Chicken” means any genetically engineered chicken, or progeny of a genetically engineered chicken, that produces chimeric Antibodies, having one or more human variable regions (i.e. the sequence of which is of human origin). For clarity, HuMab Chickens include Fixed Light Chain Chickens, and Syn VH-SD Chickens and their alternative versions.
(v)    Initiation” (and related terms such as “Initiated”) of a given Product Campaign means the first immunization of one or more Company Chicken(s) with antigen under such Product Campaign. In addition, if Antibody/ies to a given antigen are generated in a Company Chicken, prior to contracting with a Partner, but a Partner is later granted rights to such Antibody/ies and/or Derivatives thereof, then the discovery work to generate such antibody/ies qualifies as a Product Campaign and “Initiation” with respect thereto occurs upon the grant to the Partner of rights to the applicable Antibody/ies and/or Derivatives to the Partner. In the case of a Product Campaign in which immunization has occurred prior to contracting with the Partner (such as in the case that Surviving Corporation generates titers in Company Chickens to a given antigen, freezes resulting materials, and later contracts with Partners to apply the GEM assay to such materials to discover Antibodies), then Initiation occurs as of the date of agreement with the Partner for the Product Campaign, or as of the date that such Product Campaign is added to the Partner’s agreement for the Product Campaign, and in any event no later than the date upon which GEM assays commence as part of such Product Campaign.

-17-





(vi)    New Deal” means any agreement signed after the Closing Date, that (1) is not with any of Existing Collaborators 1-4 or a Parent Existing Collaborator, and (2) (a) involves a financial commitment or obligation for discovery work related to Antibodies generated in a chicken, whether HuMab Chicken or wild type chicken (“Company Chicken”) (which work may include a Product Campaign) or involves the acquisition of, or rights of any kind in or to use, Antibody/ies that were generated in a Company Chicken, or Derivative(s) thereof, or Intellectual Property rights in any of the foregoing, or permits the use of any Company Chicken by a Partner, or (b) grants rights related to a Product Campaign using a Company Chicken, and does not grant rights related to any other type of Antibody discovery. A New Deal may be created through various agreements granting rights of any kind, including, as non-limiting examples, license to the Company Intellectual Property, assignments of Company Intellectual Property, a covenant not to sue related to the Company Intellectual Property or an option to acquire or use Company Intellectual Property. For clarity, New Deal excludes the situation in which rights are granted only for use of the GEM assay with respect to Antibodies generated in mammals. Notwithstanding the foregoing definition, any agreement that (x) upon signing contains only discretionary rights, but no financial commitment or obligation, to have any Product Campaign conducted using a Company Chicken, (y) does not include any right to acquire or obtain rights to already-generated Antibodies from a Company Chicken, nor Derivatives thereof, nor to acquire rights to use a Company Chicken, and (z) does include an financial commitment or obligation for Antibody discovery or Antibodies not generated in a Company Chicken, shall not be classified as a New Deal, until and unless such discretionary right for a Product Campaign using a Company Chicken becomes an obligation (for example, upon exercise of an option for such a Product Campaign), or upon Initiation of such Product Campaign in connection with such agreement, whichever is earlier.
(vii)    New Deal Date” means, as to a given New Deal, the date that the later-signing party to such New Deal agreement signed it, or if earlier the date upon which the New Deal agreement became effective. The New Deal Date remains the same as to any given New Deal, even if its status as a New Deal is not known until sometime after the New Deal Date (which may be an extended period). Signing for this purpose may occur by exchange of electronic signatures (including PDF and facsimile exchanges). Later exchange of hard copy original signatures shall not negate the earlier date of exchange of electronic signatures. To avoid doubt, it is understood that it may not be known on or before December 31, 2019 whether certain agreements will ultimately be classified as New Deals, however, if after December 31, 2019 and before December 31, 2022 an agreement is classified as a New Deal and has a New Deal date prior to December 31, 2019, such a New Deal will count towards Milestone 12 below and if Milestone 12 is earned prior to December 31, 2022, it will be paid at such time.
(viii)    Partner” means, for purposes of this Section 2.9 only, any Person who is not a party to this Agreement and is not an Affiliate of a party to this Agreement. Notwithstanding the foregoing, if an Affiliate of the Surviving Corporation and/or Parent that is not a wholly owned Subsidiary of Parent’s corporate family engages in or holds rights to what would be considered a Product Campaign if such Affiliate were considered a Partner, then for purposes of the definition of Product Campaign, such not-wholly-owned Affiliate shall be considered a Partner.

-18-





(ix)    Product Campaign” means: (1) a project conducted by or for the Surviving Corporation, Parent, or any Affiliate of either of the foregoing, under contract with a Partner, to discover Antibodies to a given antigen, which Antibodies were generated in a Company Chicken; or (2) the granting of rights by the Company to a Partner with respect to Antibody/ies to a given antigen, which Antibody/ies were discovered in whole or in part prior to contracting with the Partner to grant the Partner rights in such Antibody/ies and were generated in a Company Chicken. For clarity: (A) projects for different Partners with respect to the same antigen each constitute a different Product Campaign; and (B) projects for different antigens conducted for the same Partner each constitute a different Product Campaign.
(x)    Syn VH-SD Chicken” means a genetically engineered chicken, or the progeny of a genetically engineered chicken, having an immunoglobulin heavy chain gene that is a functional VH3-23 gene the sequence of which is of human origin, more than one D‑gene the sequence of which is of human origin, and a single JH-gene in unrearranged format, and the same or another non-wild-type allele at the heavy chain locus.
(b)    Deferred Payments.
(i)    Milestones. In addition to the Initial Merger Consideration, Parent shall deliver or cause to be delivered to the Company Equityholders in accordance with the Closing Date Allocation Schedule (subject to Section 2.9(d) below), the amounts set forth in the table below, in cash (each, a “Milestone Payment Amount ”), in each case following the achievement by the Surviving Corporation, Parent or any of their respective Affiliates, transferees, successors or assigns of the corresponding events set forth below (each, a “Milestone”):

(ii)    Revenue Sharing.
(1)    Existing Collaborations 1-3 Revenue. Parent will pay to the Company Equityholders ten percent (10%) of all Revenue, FTE Fees, and Technology Access Fees that are Contractually Earned by Parent, Company, Surviving Corporation, or any Affiliate of either of them, during the period commencing on the Closing Date and ending on December 31, 2022, pursuant to any of Existing Collaborator Agreements 1-3, but excluding the first fifteen million dollars ($15,000,000) in such cumulative Revenue, FTE Fees, and Technology Access Fees (no share shall be due to the Company Equityholders with respect to such first fifteen million dollars ($15,000,000) of such Revenue, FTE Fees, and Technology Access Fees (collectively)).
(2)    Existing Collaboration 4 Revenue. Parent will pay to the Company Equityholders the following portion of all Revenue (which excludes FTE Fees as defined in Section 2.9(b)(ii)(4)) and Technology Access Fees that are Contractually Earned by the Company, Parent, Surviving Corporation, or any Affiliate of either of them, during the period commencing on September 8, 2017 and ending on December 31, 2022 pursuant to that certain Research Collaboration and License Agreement between the Company and Janssen Biotech Inc. dated September 8, 2017: (x) one hundred percent (100%) of such Revenue for the first one million five hundred thousand dollars ($1,500,000) in such cumulative Revenue and Technology Access Fees (it being understood that such amount is deemed paid and satisfied at Closing by virtue of the inclusion of the one million five hundred thousand dollars ($1,500,000) amount under the “J&J Tech Access Fee” entry in Schedule 1 hereto); (y) zero percent (0%) of such Revenue and Technology Access Fees for the second one million five hundred thousand dollars ($1,500,000) in such cumulative Revenue and Technology Access Fees; and (z) twenty percent (20%) of such Revenue for the remainder of such cumulative Revenue and Technology Access Fees.
(3)    Notwithstanding Sections 2.9(b)(ii)(1) and (2), Parent shall not be required to make payment to the Company Equityholders of their share of any Revenue, FTE Fees, and/or Technology Access Fees that were Contractually Earned in the applicable time period, until and unless Parent, Surviving Corporation, or any Affiliate or designee of either or both of them receives the underlying Revenue, FTE Fees, and/or Technology Access Fees.
(4)    For purposes of this Section 2.9(b)(ii):
(i)    Contractually Earned” means, with respect to a payment, that all contractual requirements for such payment to become due under the contract,

-21-





other than any requirement of invoicing and the passage of time. Any contrary definition or connotation in accounting or finance terms of art as to what “earned” means shall not apply to the interpretation of Contractually Earned. As a non-limiting example of when a payment is Contractually Earned, Revenue in the form of a milestone payment from a Partner is Contractually Earned as of the date that the corresponding milestone event is achieved, not the later date upon which the Partner is required to report upon the achievement of such milestone event, and not the later date upon which the Partner is required to make payment, which may be measured relative to the date upon which Surviving Corporation (or the entity to whom payment is due) provides an invoice, which may be divorced from the date that the underlying milestone event was achieved. For further clarity and further non-limiting example, if the fifteen million dollar ($15,000,000) exclusion under Section 2.9(b)(ii)(1) has been satisfied, and then: a milestone event for one of the deals identified in Section 2.9(b(ii)(1) is achieved on December 31, 2019, the Surviving Corporation learns of this through a notice from the Partner on January 1, 2020, the Surviving Corporation invoices for the corresponding milestone payment on February 1, 2020, and the corresponding milestone payment is actually received on April 1, 2020, that milestone payment is subject to sharing as provided for in Section 2.9(b)(ii)(1) and Parent will be required to pay ten percent (10%) thereof to the Company Equityholders after April 1, 2020 (the date on which such payment was received in this example).
(ii)    Revenue” shall mean all payments, fees and milestones (including, but not limited to, exclusivity fees, success fees, and any intellectual property, development, regulatory, or sales milestones) to be paid to Parent, Surviving Corporation, or any Affiliate or designee of either of them following the Closing Date, under the applicable Existing Collaboration (or any amendment thereto or under any agreement that may supersede or replace such agreement), but excluding any FTE Fees and/or Technology Access Fees.
(iii)    Revenue Sharing Amount” shall mean the aggregate amount payable to the Company Equityholders pursuant to Section 2.9(b)(ii)(1) and Section 2.9(b)(ii)(2).
(iv)    FTE Fees” shall mean amounts to be paid to Parent, Company, Surviving Corporation, or any Affiliate or designee of any of them, under the applicable Existing Collaboration (or any amendment thereto or under any agreement that may supersede or replace such Existing Collaboration), to fund the costs of the services of an employee or consultant performed under such agreement, at the fully burdened rate, not to exceed three hundred thousand dollars ($300,000) per FTE per year for FTEs actually devoted to performing such services.
(v)    Existing Collaborators 1-3” means those Persons listed in Section 2.9(b)(ii)(4)(vi) of the Company Disclosure Letter.
(vi)    Existing Collaborator 4” means that Person listed in Section 2.9(b)(ii)(4)(vii) of the Company Disclosure Letter.

-22-





(vii)    Existing Collaborator Agreements 1-3” means those agreements listed in Section 2.9(b)(ii)(4)(viii) of the Company Disclosure Letter.
(viii)    Parent Existing Collaborators” means those Persons listed on Schedule 3 attached hereto.
(ix)    Technology Access Fees” shall mean any payment received in consideration for execution of a license agreement for access to the Company’s proprietary technology and that is due within ninety (90) days after the signing of such Existing Collaborator Agreement 1-3 or the agreement referenced in Section 2.9(b)(ii)(2) (ignoring the timing upon which any invoice is provided – i.e., contingency upon receipt of an invoice and/or the possibility of late invoicing or actual late invoicing shall not alter whether a payment is considered a Technology Access Fee or not).
(c)    Copies of Amendments and Agreements. In connection with the delivery of an Earn-Out Statement, Parent shall provide to the Shareholders’ Representative a copy of each any every amendment to an Existing Collaboration, and each New Deal and/or other document that will govern or may give rise to a payment obligation under this Section 2.9 (including research plan amendments or amendments to similar ancillary documents that may affect whether any given payment(s) will be due), and each and every amendment to any of the foregoing documents executed since the delivery of the prior Earn-Out Statement.
(d)    Payment.
(i)    Subject to Section 2.9(d)(ii) and 2.9(d)(iv) below, Milestone Payment Amounts and Revenue Sharing Amounts due in accordance with this Section 2.9 will be payable by Parent to the Company Equityholders on a semi-annual basis, on or before the end of the calendar half year following the accounting period the underlying Milestone was achieved or Revenue, FTE Fees and/or Technology Access Fees were received.
(ii)    With respect to each accounting period during the Earn-Out Period, Parent will prepare at its expense and deliver to the Shareholders’ Representative, no later than thirty (30) calendar days after each Earn-Out Reporting Date, a statement (each an “Earn-Out Statement”), setting forth in reasonable detail Parent’s good faith calculation of any Milestone Payment Amounts or Revenue Sharing Amounts that will be due for such period, including a description of all Milestones achieved and all Revenue, FTE Fees, and Technology Access Fees that are received under Section 2.9(b)(ii) and any amounts subject to Right of Setoff. If no such amounts are to be paid for such period, Parent will nevertheless provide the Shareholders’ Representative with an Earn-Out Statement for such period indicating the lack of any such amounts being due. Parent will, upon the written request of the Shareholders’ Representative, promptly make available to the Shareholders’ Representative as reasonably necessary or appropriate to confirm the amounts set forth in such Earn-Out Statement (1) a copy of relevant workpapers, commercial contracts, financial information and any other relevant books and records utilized by Parent in the preparation of such Earn-Out Statement, subject to redactions to preserve attorney-client privilege of such records, and (2) employees of Parent involved in the preparation of such Earn-Out Statement. The Shareholders’ Representative shall

-23-





have the right to disclose, in confidence, all such documents received by it to its chosen legal and accounting professionals, and to have its legal and financial professionals (including outside counsel and an outside accountant or accounting firm) audit Parent’s and its Affiliates’ records on-site.
(iii)    Each Milestone Payment Amount and Revenue Sharing Amount shall be subject to the Right of Setoff and payable: (x) only one time, (y) only for the first achievement of the applicable Milestone or item of Revenue, FTE Fees, and Technology Access Fees, as applicable and (z) subject to the limitations set forth in Section 2.8 and the reductions set forth in Section 2.9(d)(iv).
(iv)    Subject to the Right of Setoff and reductions set forth in this Section 2.9(d)(iv), any amounts that Parent is required to pay under this Section 2.9 shall be paid in full no later than thirty (30) days after final determination of such payment pursuant to Section 2.9(e); provided, however, that if the Company shall timely deliver an Earnout Payment Dispute Notice to Parent, then Parent shall remit payment of the undisputed portion(s) of any Milestone Payment Amount and/or Revenue Sharing Amount within thirty (30) days of its receipt of the Earnout Payment Dispute Notice, and shall reserve any disputed amounts that are or would be effected by the resolution of the disputed items until a final determination is made with respect to such amounts per Section 2.9(e). Each Milestone Payment Amount and/or Revenue Sharing Amount shall be reduced by (1) the amount of Taxes payable by Parent, the Company, the Surviving Corporation or their Subsidiaries with respect to the amounts payable to the Company Optionholders in respect of the applicable Milestone Payment Amount and/or Revenue Sharing Amount, and (2) any Post-Closing Transaction Expenses attributable to such Milestone Payment Amount and/or Revenue Sharing Amount (the amount payable to the Equityholders after such reductions, the “Adjusted Milestone Payment Amount” or “Adjusted Revenue Sharing Amount,” as applicable). Any Adjusted Milestone Payment Amount and/or Adjusted Revenue Sharing Amount shall be paid to the Equityholders according to the following procedures: Parent shall (1) pay or cause to be paid to each of the Company Shareholders, by wire transfer of immediately available funds, an amount per share of Common Stock held by such Company Shareholder immediately prior to the Effective Time equal to the Milestone Per Share Consideration and/or Revenue Sharing Per Share Consideration, as applicable, payable upon the achievement of the applicable Milestone or Revenue Sharing Amount threshold in accordance with the Closing Date Allocation Schedule, and (2) cause the Surviving Corporation to pay to each of the Company Optionholders an amount per share of Common Stock underlying any Company Options held by such Company Optionholder immediately prior to the Effective Time equal to the Milestone Per Share Consideration and/or Revenue Sharing Per Share Consideration, as applicable, payable upon the achievement of the applicable Milestone or Revenue Sharing Amount threshold in accordance with the Closing Date Allocation Schedule, subject to all applicable withholding Taxes; provided, that Parent shall be under no obligation to pay any amounts under this Section 2.9 until it has received an updated Closing Date Allocation Schedule from the Shareholders’ Representative setting forth the amounts of such Adjusted Milestone Payment Amount and/or Adjusted Revenue Sharing Amount that each Company Equityholder is entitled to receive from such payments and any Post-Closing Transaction Expenses attributable to such payments.

-24-





(v)    If any audit or review reveals an underpayment by Parent with respect to any payments due under this Section 2.9, Parent shall promptly pay to the Company Equityholders the amount of such underpayment. If any such audit or review reveals that the undisputed monies owed by Parent to the Company Equityholders has been understated by more than five percent (5%) for any accounting period, Parent shall, in addition, pay the costs of such audit or review. Any overpayment shall be credited against the next payment due hereunder, and shall not be required to be disgorged by the Company Equityholders.
(vi)    It is expressly understood and agreed that Parent, the Surviving Corporation and their respective Affiliates shall have no liability to any Company Equityholder for its portion of any amounts due under this Section 2.9, which amount has been paid or delivered, as applicable, in full by or on behalf of Parent in accordance with the Closing Date Allocation Schedule as updated by the Shareholders’ Representative in accordance with Section 2.9(d)(iv) and Section 6.12.
(e)    Earnout Payment Dispute Resolution.
(i)    Earnout Payment Disputes.
(1)    Earnout Payment Dispute Notice. In the event that the Shareholders’ Representative shall dispute the purported occurrence or non-occurrence of a Milestone, then the Shareholders’ Representative may provide written notice to Parent (the “Earnout Payment Dispute Notice”) specifying the amount disputed and the basis for the dispute, together with supporting documentation reflecting the analysis and justification thereof. Parent and the Shareholders’ Representative shall thereafter attempt to resolve the dispute as set forth in Section 2.9(e)(ii)-(iii). Parent and the Surviving Corporation shall provide the Shareholders’ Representative with reasonable and timely access to information with respect to the subject matter of the dispute, at no charge, other than actual out-of-pocket external costs incurred by Parent or the Surviving Corporation for photocopying, faxes, postage and the like, which costs shall be reimbursed by the Shareholders’ Representative.
(2)    The Shareholders’ Representative and Parent shall attempt to resolve any dispute arising out of or relating to this Agreement promptly by negotiation in good faith between the Shareholders’ Representative and an officer of Parent who has authority to settle the dispute. Parent shall give the Shareholders’ Representative written notice of any dispute not resolved in the ordinary course of business (the “Other Dispute Notice”). Within twenty (20) Business Days following delivery of such notice, the Shareholders’ Representative shall submit to Parent a written response thereto. If a dispute regarding this Section 2.9 is not resolved in the ordinary course of business, but Parent does not provide the Other Dispute Notice, then the Shareholders’ Representative shall be entitled to provide the Other Dispute Notice to Parent, and Parent will be required to respond in writing within twenty (20) Business Days. In all cases, the notice and the response shall include: (i) a statement of each party’s position(s) regarding the matter(s) in dispute and a summary of arguments in support thereof; and (ii) the name and title of the officer who will represent Parent and any other Person who will accompany that officer, in the case of Parent, or the name of the agent who will represent the

-25-





Company Equityholders and any other Person who will accompany that agent, in the case of the Company Equityholders.
(ii)    In Person Meeting. Within thirty (30) days following delivery of a Earnout Payment Dispute Notice or an Other Dispute Notice, the agent who will represent the Company Equityholders and the designated officer of Parent shall meet at a mutually acceptable time and place, and thereafter, as often as they reasonably deem necessary, to attempt to resolve the dispute. All negotiations conducted pursuant to this Section 2.9(e)(ii) (and any of the parties’ submissions in contemplation hereof) shall be kept confidential by the Parties and shall be treated by the Parties and their representatives as compromise and settlement negotiations under the Federal Rules of Evidence and any similar state rules.
(iii)    Mediation. In the event that the Shareholders’ Representative and Parent are unable to resolve any dispute arising out of this Agreement in accordance with the provisions of this Section 2.9(e)(iii), the parties shall attempt in good faith to resolve such dispute by confidential, non-binding mediation submitted to JAMS, or its successor, in San Diego, California before resorting to arbitration. If the parties have not agreed on a mediator within fourteen (14) days after the dispute was referred for mediation, the mediator shall, upon request of any party, be appointed pursuant to the JAMS mediation procedures. The cost of mediation shall be borne equally by the parties. No statements made by any party during the mediation may be used by another party or referred to in any subsequent proceedings. Any dispute not resolved within forty-five (45) days (or within such other time period as may be agreed to by parties in writing) after appointment of a mediator shall be finally resolved by binding arbitration, which may be demanded by either Party by providing a notice of arbitration (“Arbitration Request”) to the other party.
(iv)    Arbitration. Within ten (10) days following the delivery of an Arbitration Request, the parties shall submit the dispute for binding arbitration. The binding arbitration shall be held in San Diego, California in accordance with the Commercial Arbitration Rules and the Expedited Procedures of the American Arbitration Association (“AAA”) then in effect (the “Commercial Rules”), except as modified herein. The arbitration shall be held and the award shall be issued in San Diego, California before three (3) arbitrators, agreed to by Parent and the Shareholders’ Representative or, if they are unable to agree, appointed by the AAA in accordance with listing, ranking and striking provisions in the Commercial Rules. Any arbitrator appointed by the AAA shall be a retired judge or a practicing attorney with no less than twenty (20) years of experience with large, complex, commercial cases and an experienced arbitrator; provided that at least one of the arbitrators shall be a retired judge. Notwithstanding any contrary provision of the Commercial Rules, the parties shall be entitled to complete discovery in any arbitration proceeding, including reasonable document requests, interrogatories, and depositions in any manner and to the extent permitted or authorized by the Federal Rules of Civil Procedure in the United States as interpreted by the U.S. Federal courts. In rendering the award, the arbitrators shall be required to apply the substantive Law of the State of California to the express terms of this Agreement. The award of the arbitrators shall be in writing and shall briefly state the findings of fact and conclusions of Law on which it is based. The award shall be final and binding upon the parties and shall be the sole and exclusive remedy between the parties

-26-





regarding any claims, counterclaims, issues or accountings presented to the arbitrators. Judgment upon the award may be entered and enforced in any court having jurisdiction.
(v)    Payment of Fees. There shall be no fee-shifting and the arbitral panel shall not be empowered to award attorneys’ fees and costs. The parties shall share equally the fees of the arbitrators and the AAA.
(f)    Conduct of the Business. During the Earn-Out Period, Parent shall use Commercially Reasonable Efforts to achieve all Milestones and generate Revenues, Technology Access Fees, and FTE Fees that would result in payments under Section 2.9(b). For purposes of this Section 2.9(f), “Commercially Reasonable Efforts” means, with respect to activities directed at the achievement of Milestones and generation of Revenues, Technology Access Fees, and FTE Fees that would result in payments under Section 2.9(b), the carrying out of such activities using efforts and resources comparable to the efforts and resources commonly used by a similarly sized company of the Company as of the Closing Date in the research-based bio pharmaceutical industry for technologies, compounds or products of similar commercial and scientific potential at a similar stage in development or product life, taking into account relevant factors, including the competitive landscape, the nature and extent of market exclusivity (including patent coverage and regulatory exclusivity), the likelihood, timing or existence of generic products, technical, legal, scientific, and medical factors, a product’s safety and efficacy, its time and cost to develop, the likelihood of regulatory approval, regulatory concerns (including anticipated or approved labeling and anticipated or approved post-approval requirements), strategic planning, present and future market and commercial potential (including competitive market conditions, the size of the particular market in the applicable country for the relevant indication, and the probability of profitability of the relevant product or service in light of existing and anticipated competitive products and services, including the amounts of marketing and promotional expenditures with respect to achievement of the Milestones, its reasonably expected or actual pricing, reimbursement and formulary status, and the cost of any studies necessary or reasonably useful to obtain favorable pricing, reimbursement or formulary status for any product, the advantages of a discovery technology over other available discovery technologies, and all other relevant factors, including commercial, technical, legal, scientific, or medical factors. To avoid doubt, Commercially Reasonable Efforts shall be evaluated without reference to the payments under this Section 2.9 (i.e., the fact that achieving the Milestones and Contractually Earning the applicable revenues will lead to a payment obligation by Parent under this Section 2.9 shall not be used to lessen the activities and effort that must be put forth by Parent, on the theory that it is “Commercially Reasonable” to avoid the payments). Without limiting the generality of the foregoing in this Section 2.9(f), applying Commercially Reasonable Efforts in accordance with the first sentence of this Section requires all of the following:
(i)    Parent, Surviving Corporation and their Affiliates shall not delay the Initiation of any Product Campaign or the signing of any New Deal for the purpose of avoiding payment of a milestone under Section 2.9(a) that would otherwise have come due in the absence of the delay;

-27-





(ii)    Parent, Surviving Corporation and their Affiliates shall not delay the Contractual Earning of any Revenue, FTE Payment, or Technology Access Fees for the purpose of avoiding sharing of such Revenue, FTE Payment, or Technology Access Fees under Section 2.9(b);
(iii)    Parent, Surviving Corporation and their Affiliates shall not delay invoicing for any Revenue, FTE Payment, or Technology Access Fee that is subject to sharing under Section 2.9(b) and has been Contractually Earned during the Earn-Out Period for the purpose of avoiding sharing of such Revenue, FTE Payment, or Technology Access Fees under Section 2.9(b);
(iv)    Parent, Surviving Corporation and their Affiliates shall not amend any of Existing Collaboration Agreements 1-3 nor the agreement referenced in Section 2.9(b)(ii)(2) in each case for the purpose of reducing payments due in connection with Section 2.9(b)(ii); and
(v)    Parent, Surviving Corporation and their Affiliates shall not structure any transaction involving Company Intellectual Property, HuMab Chicken(s), Antibody/ies discovered, generated, or identified using any Company Intellectual Property and/or HuMab Chicken(s), Derivative(s) of any such Antibodies, and/or Intellectual Property in any of the foregoing, for the purpose of avoiding any milestone payable pursuant to this Section 2.9, including (without limitation) through the use of an Affiliate holding any rights related to any of the foregoing, and/or through the grant of right to acquire the Affiliate rather than a direct grant of rights in the applicable Intellectual Property, Product Campaign, technology, or subject matter to the Third Party.
(g)    Certain Limitations. The parties understand and agree that the amounts payable under this Section 2.9 are an integral part of the Merger Consideration, and the rights to receive such amounts will not be represented by any form of certificate. The rights to receive such amounts are not transferable, except by operation of law or by will or the laws of descent and distribution, by or to a trust or other estate planning vehicle, and/or to family member(s). The rights to receive such amounts do not possess any attributes of capital stock of the Company, Parent or the Surviving Corporation or constitute an equity or ownership interest in the Company, Parent or the Surviving Corporation, and no Company Equityholder will have rights as a shareholder, option holder or warrant holder of the Surviving Corporation or Parent as a result of his, her or its right to receive a portion of the Milestone Payment Amount or Revenue Sharing Amount and no interest is payable with respect to the Milestone Payment Amount or Revenue Sharing Amount. Any attempted transfer of any right to receive a Milestone Payment Amount or Revenue Sharing Amount by any Company Equityholder (other than as permitted by the second sentence of this Section 2.9(g)) shall be null and void.
2.10    No Further Ownership Rights in Common Stock. All consideration paid upon the surrender for exchange of shares of Common Stock (including Restricted Stock) in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Common Stock, and there shall be no further registration of transfers on the records of the Surviving Corporation of shares of Common Stock which were outstanding

-28-





immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article II.
2.11    Lost, Stolen or Destroyed Certificates.  In the event any Certificates shall have been lost, stolen, mutilated, defaced or destroyed, upon the making of an affidavit of fact reasonably acceptable to Parent by the Person claiming such Certificate to be lost, stolen, mutilated, defaced or destroyed, and, if required by Parent, an agreement by such Person to indemnify Parent against any claim that may be made against it with respect to such Certificate, the Surviving Corporation shall, subject to Section 2.8(a), pay in exchange for such lost, stolen, mutilated, defaced or destroyed Certificate the amount of Merger Consideration such Person would have been entitled to receive had such Person surrendered such lost, stolen, mutilated, defaced or destroyed Company Certificate to the Surviving Corporation pursuant to Section 2.8(a).
2.12    Purchase Price Adjustment
(a)    Closing Notice.
(i)    At least two (2) Business Days prior to the Closing Date, the Company shall deliver to Parent a written notice executed by an authorized officer of the Company (the “Closing Notice”), setting forth good faith estimates of: (1) the Final Estimated Net Closing Cash Amount, (2) the Company’s Transaction Expenses that are unpaid as the Effective Time, and (3) any Change in Control Payments that are unpaid as of the Effective Time, in each case as of the Effective Time (clauses (1) through (4) collectively the “Initial Merger Consideration Inputs”) (for the avoidance of doubt, in no event will any amounts under (2) or (3) also be included in the calculations for (1) to the extent it would cause such amounts to be double counted).
(b)    Draft Closing Statement.
(i)    As soon as practicable following the Effective Time, Parent will cause the Surviving Corporation to prepare a report setting forth the actual amounts of the Initial Merger Consideration Inputs as of the date hereof and the Effective Time, along with a summary showing in reasonable detail the Surviving Corporation’s calculation of such amounts (the “Draft Closing Statement”). Parent shall deliver the Draft Closing Statement to the Shareholders’ Representative not later than ninety (90) days following the Closing Date.
(ii)    The Draft Closing Statement shall also set forth the determination of Net Closing Cash and the Net Closing Cash True-Up Amount, if any.
(c)    Review by Shareholders’ Representative. As soon as practicable, but in any event within thirty (30) days of receipt of the Draft Closing Statement, the Shareholders’ Representative shall provide to Parent a written report indicating its agreement with, or specific, itemized and quantified objections to, the Draft Closing Statement (the “Shareholders’ Representative’s Report”), including the calculation of the Initial Merger Consideration Inputs,

-29-





Net Closing Cash and the Net Closing Cash True-Up Amount, if any. During such period, Parent shall permit the Shareholders’ Representative reasonable access to the Surviving Corporation’s books and records and personnel to the extent necessary to review the Draft Closing Statement; provided, that the Shareholders’ Representative shall treat all such information as confidential information of Parent. All other items on the Draft Closing Statement which have not been cited in the Shareholders’ Representative’s Report shall be deemed accepted by the Shareholders’ Representative. Failure by the Shareholders’ Representative to object to the Draft Closing Statement within such period shall be deemed to be the Shareholders’ Representative’s acceptance of the entire Draft Closing Statement and all items therein.
(d)    Agreement on Closing Statement.
(i)    Within fifteen (15) days of the receipt by Parent of the Shareholders’ Representative’s Report, the Shareholders’ Representative and Parent shall endeavor in good faith to agree on any matters in dispute. Any matter that Parent chooses not to dispute on the Shareholders’ Representative’s Report within such fifteen (15) day period shall be deemed accepted by Parent.
(ii)    If Parent and the Shareholders’ Representative are unable to agree on any remaining matters in dispute within fifteen (15) days after Parent’s receipt of the Shareholders’ Representative’s Report, then the matters in dispute will be submitted for resolution to a nationally recognized certified public accounting firm that has not performed accounting, tax or auditing services for Parent, the Company or any of their respective Affiliates during the previous five (5) years, as may be mutually acceptable to Parent and the Shareholders’ Representative (any of the foregoing selected to resolve the dispute, an “Appraiser”),which shall within thirty (30) days of such submission determine and issue a written report to the Shareholders’ Representative and Parent upon such disputed items (in no event enlarging or adding any new or additional item to those set forth in the Shareholders’ Representative’s Report and not accepted by Parent), and such written decision shall be final and binding upon the parties hereto. The Shareholders’ Representative and Parent shall cooperate reasonably with each other and each other’s representatives to enable the Appraiser to render a written decision as promptly as possible. The fees and expenses of the Appraiser shall be borne by the Shareholders’ Representative and Parent in inverse proportion to their respective success on the merits and such allocation of fees and expenses shall be calculated by the Appraiser and shall be final and binding on the parties. At any time, Parent and the Shareholders’ Representative may agree to settle any objections raised in the Shareholders’ Representative’s Report, which agreement shall be in writing and binding upon each of Parent and the Shareholders’ Representative with respect to the subject matter of any such objection so resolved.
(iii)    The Draft Closing Statement, revised to incorporate the resolution of any matters in dispute pursuant to Sections 2.12(c), 2.12(d)(i) and/or 2.12(d)(ii), as applicable, or the Closing Notice in the event that Parent does not deliver a Draft Closing Statement not later than sixty (60) days following the Closing Date, is referred to as the “Closing Statement.” The Closing Statement shall have the legal effect of an arbitral award and shall be final, binding and conclusive on the parties hereto.

-30-





(e)    Adjustment to Merger Consideration.
(i)    Net Closing Cash Adjustment.

There is not, under any of the Leases, any material default by the Company, nor, to the Knowledge of the Company, by any other party thereto, and no event has occurred that with the lapse of time or the giving of notice or both would constitute a material default thereunder.

Each of Parent and Merger Sub is a corporation duly organized, validly existing and in good standing under the laws of their state of incorporation, has the requisite power and authority to own, lease and operate its properties and to carry on its business as now being conducted and is duly qualified or licensed and in good standing to do business in each jurisdiction in which the nature of its business or the ownership or leasing of its properties makes such qualification or licensing necessary, other than in such jurisdictions where the failure to be so qualified or licensed or to be in good standing, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect on Parent.
4.2    Merger Sub. The authorized capital stock of Merger Sub consists of 1,000 shares of common stock, par value $0.001 per share, of which 1,000 shares are issued and outstanding. Parent is the sole shareholder of Merger Sub and is the legal and beneficial owner of all issued and outstanding shares of Merger Sub.

-54-





the performance by Parent and Merger Sub of their respective obligations hereunder, and the consummation of the Transactions have been duly authorized by all necessary corporate action on the part of Parent and Merger Sub and no other corporate or other proceedings or actions on the part of Parent or Merger Sub are necessary to authorize the execution and delivery of this Agreement or to consummate the Merger and the other Transactions, subject only to the filing of the Agreement of Merger pursuant to the California Code.

4.4    Compliance. Neither Parent nor any of its Subsidiaries is or has been in conflict with, or in default or in violation of, any Legal Requirement applicable to Parent or any of its Subsidiaries or by which Parent or any of its Subsidiaries or any of their respective businesses or properties is bound or affected, except for those conflicts, defaults or violations that, individually or in the aggregate, would not cause Parent to lose any material benefit or incur any material Liability. Parent has not received any written notice of or been charged with any material default

-55-





or violation of any such Legal Requirements. There is no judgment, injunction, order or decree binding upon Parent or any of its Subsidiaries which has or would reasonably be expected to have the effect of prohibiting or materially impairing the businesses conducted by Parent or any of its Subsidiaries as of the date hereof or the acquisition of material property by Parent or any of its Subsidiaries.
4.5    Litigation. There are no claims, suits, actions, proceedings or investigations of any nature pending or, to the knowledge of Parent, threatened in writing against, relating to or affecting Parent, Merger Sub or any of Parent’s other Subsidiaries, or the assets or properties of Parent or Merger Sub, before any court, governmental department, commission, agency, instrumentality or authority, or any arbitrator that seeks to restrain or enjoin the consummation of the Transactions or which would reasonably be expected, either singularly or in the aggregate with all such claims, actions or proceedings, to have a Material Adverse Effect on the ability of Parent and Merger Sub to perform their respective obligations under this Agreement or consummate the Transactions, nor, to Parent’s knowledge, is there any reasonable basis therefor, or any facts, threats, claims or allegations that would reasonably be expected to result in any such threatened or pending action, suit, proceeding or investigation.

6.6    Tax Matters.
(a)    Tax Returns.
(i)    The Company shall prepare and timely file, or cause to be prepared or timely filed, all Tax Returns of the Company that are required to be filed (taking into account any extension) on or before the Closing Date, and shall pay, or cause to be paid, all Taxes of the Company due on or before the Closing Date. Such Tax Returns shall be prepared by treating items on such Tax Returns in a manner consistent with the past practices of the Company, except as required by applicable law. At least ten (10) Business Days prior to filing any such Tax Return, the Company shall submit a copy of such Tax Return to Parent for Parent’s review and approval, which approval shall not be unreasonably withheld.
(ii)    Parent shall prepare and timely file, or cause to be prepared and timely filed, all Tax Returns for the Company for any periods ending on or prior to the Closing Date that are filed after the Closing Date and all Tax Returns for the Company for any Straddle Periods. Parent shall deliver to the Shareholders’ Representative for the Shareholders’ Representative’s review and comment a copy of each such Tax Return at least fifteen (15) Business Days prior to the due date for the filing of such Tax Return (taking into account any extension). Parent shall consider in good faith any comments that are received from the Shareholders’ Representative at least five (5) Business Days prior to the due date for the filing of such Tax Return. The Company Equityholders shall be responsible for all Taxes relating to the Pre-Closing Tax Period payable in connection with such Tax Returns but only to the extent such Taxes were included in the calculation of Net Closing Cash. The Shareholders’ Representative and Parent shall instruct the Escrow Agent to release from the Escrow Fund the amount due to Parent for the Company Equityholders’ share of Taxes relating to the Pre-Closing Tax Period under this Section 6.6(a)(ii) at least two (2) Business Days before payment of Taxes (including estimated Taxes) is due to the Tax Authority, except to the extent such Taxes were taken into account in the calculation of Net Closing Cash. For purposes of this Agreement, the pre-closing portion of any Taxes that are payable with respect to any Straddle Period will be: (1) in the case of Property Taxes, deemed to be the amount of such Taxes for the entire Straddle Period multiplied by a fraction, the numerator of which is the number of calendar days of such Straddle Period in the Pre-Closing Tax Period and the denominator of which is the number of calendar days in the entire Straddle Period; provided, however, that only property that was owned by the Company as of the Closing shall be included in this calculation; and (2) in the case of all other Taxes, determined as though the taxable year of the Company terminated at the close of business on the Closing Date.
(b)    Tax Contests. Parent and the Surviving Corporation, on the one hand, and the Shareholders’ Representative, on the other hand, shall promptly notify each other upon receipt by such party of written notice of any inquiries, claims, assessments, audits or similar events with respect to Taxes relating to a Pre-Closing Tax Period (any such inquiry, claim, assessment, audit or similar event, a “Tax Contest”). Any failure to so notify the other party of any Tax Contest shall not limit any of the indemnification obligations under Article VIII (except to the extent such failure actually prejudices the defense of such Tax Contest). Parent shall have

-62-





the right to control the conduct of all Tax Contests, including any settlement or compromise thereof; provided, however, that the Parent shall keep Shareholders’ Representative reasonably informed of the progress of any such Tax Contest and Parent shall not effect any such settlement or compromise with respect to which the Company Equityholders are liable without Shareholders’ Representative’s written consent, which consent shall not be unreasonably withheld, conditioned or delayed. Each party shall bear its own costs for participating in such Tax Contest, except that Parent may be entitled to indemnification for its costs pursuant to this Agreement. In the event of any conflict or overlap between the provisions of this Section 6.6(a)(ii) and Section 8.6, the provisions of this Section 6.6(a)(ii) shall control.

Parent, the Surviving Corporation and the Shareholders’ Representative 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 Agreement and any Tax Contest. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information which may be reasonably relevant to any such Tax Return or Tax Contest and making appropriate persons available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.
(d)    Transfer Taxes. All transfer, stamp, documentary, sales, use, registration, value-added and other similar Taxes (including all applicable real estate transfer Taxes) incurred in connection with this Agreement and the Transactions (“Transfer Taxes”) will be borne by the Company Equityholders. The Company (or Surviving Corporation, as applicable) hereby agrees to file, or cause to be filed, in a timely manner all necessary documents (including, but not limited to, all Tax Returns) with respect to such Transfer Taxes. The Company (or Surviving Corporation, as applicable) shall provide Parent with evidence satisfactory to Parent that such Transfer Taxes have been paid by (or on behalf of) the Company Equityholders.
6.7    FIRPTA Compliance. On the Closing Date, the Company shall deliver to Parent a properly executed statement, dated as of the Closing Date, in a form reasonably acceptable to Parent and that satisfies the requirements of Treasury Regulation Sections 1.1445‑2(c)(3) and 1.897-2(h), together with the required notice to the IRS and written authorization for Parent to deliver such notice and a copy of such statement to the IRS on behalf of the Company upon the Closing.
6.8    Third Party Consents. Prior to the Closing Date, (a) the Company shall obtain and provide to Parent all consents and waivers required in connection with the Merger from third parties to all Company Material Contracts, and (b) the Company shall use commercially reasonable efforts to obtain and provide to Parent all consents and waivers required in connection with the Merger from third parties to all other Contracts to which the Company is a party and which are listed in Section 6.8 of the Company Disclosure Letter. If the lessor or licensor under any Lease conditions its grant of a consent (including by threatening to exercise a “recapture” or other termination right) upon, or otherwise requires in response to a notice or consent request regarding this Agreement, the payment of a consent fee, “profit sharing” payment or other consideration (including increased rent payments), or the provision of additional security

-63-





(including a guaranty), the Company shall be solely responsible for making all such payments or providing all such additional security.
6.9    Merger Sub Compliance. Parent shall cause Merger Sub to comply with all of Merger Sub’s obligations, as applicable, under or relating to this Agreement. Neither Merger Sub shall engage in any business which is not in connection with the Merger pursuant to this Agreement.
6.10    Notification of Certain Matters. The Company shall give prompt written notice to Parent of (a) any notice or other communication from any third party alleging that the consent of such third party is or may be required in connection with the Transactions, (b) any notice or other communication from any third party whose consent is required in connection with the Transactions that such third party refuses to give such consent, (c) any Material Adverse Effect on the Company, (d) any breach of any of the Company’s representations, warranties, agreements, obligations or covenants pursuant to this Agreement or (e) the occurrence or existence of any event that results, or with notice or the passage of time or otherwise, is reasonably likely to result, in the failure of the conditions set forth in Article VII; provided, however, that the delivery of notice pursuant to this Section 6.10 shall not limit or otherwise affect the remedies available hereunder to Parent.
6.11    Section 280G of the Code.
(a)    Parent and the Company acknowledge that the consideration payable pursuant to this Agreement and certain other amounts which may be received by any person in connection with the Transactions may be deemed to constitute “parachute payments” (within the meaning of Section 280G of the Code and the regulations promulgated thereunder (“Section 280G”)). The Company shall obtain and deliver to Parent, prior to the solicitation of the requisite approval of the Company’s shareholders described in Section 6.11(b), a Section 280G Waiver from each person who is a “disqualified individual” (within the meaning of Section 280G), as determined immediately prior to the initiation of the solicitation of the requisite approval of the Company’s shareholders described in Section 6.11(b), and who might otherwise receive or have the right or entitlement to receive a parachute payment under Section 280G in connection with the Transactions, unless the requisite approval of the Company’s shareholders of such parachute payments is obtained pursuant to Section 6.11(b).
(b)    As soon as practicable following the delivery by the Company to Parent of the Section 280G Waivers, the Company shall submit to the Company’s shareholders for approval in accordance with Section 280G(b)(5)(B) of the Code any payments and/or benefits that are subject to a Section 280G Waiver, such that such payments and benefits shall not be deemed to be “parachute payments” under Section 280G, and prior to the Effective Time the Company shall deliver to Parent evidence reasonably satisfactory to Parent (i) that a vote of the Company’s shareholders was solicited in conformance with Section 280G, and the requisite approval of the Company’s shareholders was obtained with respect to any payments and/or benefits that were subject to such vote (the “Section 280G Approval”) or (ii) that the Section 280G Approval was not obtained and as a consequence, pursuant to the Section 280G Waiver, such “parachute payments” shall not be made or provided.

-64-





(c)    The form of the Section 280G Waiver and any materials to be submitted to the Company’s shareholders in connection with the Section 280G Approval (the “Section 280G Soliciting Materials”) shall be subject to review and approval by Parent, which approval shall not be unreasonably withheld.
6.12    Closing Date Allocation Schedule. At least three (3) Business Days prior to the Closing, the Company shall deliver to Parent the Closing Date Allocation Schedule, and thereafter through the Closing any interim updates to the Closing Date Allocation Schedule as necessary for the information reflected thereon to be accurate in all material respects as of the Closing Date.

(c)    The obligations of Parent and the Surviving Corporation under this Section 6.13 shall not be terminated or modified in such a manner as to adversely affect any Company Indemnified Party to whom this Section 6.13 applies without the consent of such affected Company Indemnified Party unless such termination or modification is required by applicable law. The provisions of this Section 6.13 are intended to be for the benefit of, and shall be enforceable by, each Company Indemnified Party, his or her heirs and his or her representatives, and are in addition to, and not in substitution for, any other rights to which each Company Indemnified Party is entitled, whether pursuant to law, contract or otherwise.

ARTICLE VIII.    
SURVIVAL OF REPRESENTATIONS AND WARRANTIES; INDEMNIFICATION; ESCROW
8.1    Survival of Representations and Warranties
(a)    All representations and warranties of the Company contained in this Agreement and any certificate delivered by the Company pursuant to this Agreement shall survive the consummation of the Merger and continue until the Escrow Termination Date, at which time such representations and warranties shall terminate; provided, however, that the representations and warranties in Section 3.8(h)(i) (Intellectual Property) (the “Specified IP Representation”) and related indemnity obligations shall survive until the date that is two (2) years following the Closing Date (the “Specified IP Representation Survival Period”); provided, further ,that Section 3.1 (Organization; Standing and Power; Governing Documents; Subsidiaries), Section 3.2 (Capital Structure), Section 3.3 (Authority; Non-Contravention; Necessary Consents), the representations and warranties in Section 3.7 (Taxes) and Section 3.11 (Brokers’ and Finder’s Fees; Fees and Expenses) (together, the “Fundamental Representations”) and related indemnity obligations will survive until thirty (30) days after the expiration of the applicable statute of limitations (the “Survival Period”); provided, further, that if at any time prior to the termination of any specific representation or warranty, an Indemnified Party has duly delivered to the Shareholders’ Representative a valid Indemnification Demand or Claim Notice (with such Indemnification Demand or Claim Notice satisfying the requirements set forth in Sections 8.6(a) or 8.7(a), as applicable) relating to such representation or warranty, then the representation or warranty underlying the claim asserted in such Indemnification Demand or Claim Notice shall survive until such time as such claim is resolved. The Company and Parent expressly agree pursuant to this Section 8.1 to shorten the statutes of limitation applicable to all claims and causes of action based directly or indirectly upon inaccuracies in or breaches of the representations and warranties other than the Fundamental Representations made by the Company in this Agreement. The respective covenants, agreements and obligations of the parties contained in this Agreement shall survive (i) until fully performed or fulfilled, unless non-compliance with such covenants, agreements or obligations is waived in writing by the party or parties entitled to such performance, or (ii) if not fully performed or fulfilled, until the later of the end of the applicable statute of limitations and any extensions thereof. Notwithstanding the fact that the Specified IP Representation Survival Period extends past the Escrow Termination Date, in no event shall any amounts withheld from the Company Equityholders under the Right of Setoff with respect to breaches of the Specified IP Representation, when combined with all amounts recovered by Parent from the Escrow Fund, exceed the Escrow Amount.
(b)    The representations, warranties, agreements, obligations and covenants of the Company, and the rights and remedies that may be exercised by the Indemnified Parties, shall

-70-





not be limited or otherwise affected by or as a result of any information furnished to, or any investigation made by or knowledge of, the Indemnified Parties or their representatives.
8.2    Escrow Deposits.
(a)    Escrow Fund. Promptly at the Closing, and without any act of any Company Equityholder, Parent shall deposit the Escrow Amount with the Escrow Agent. For purposes of determining the reduction in the amount of Merger Consideration payable to each Company Equityholder pursuant to Section 2.7, Parent will be deemed to have contributed on behalf of each Company Equityholder, his, her or its pro rata portion of the Escrow Amount to the Escrow Fund to be governed under the terms set forth in this Agreement and in the Escrow Agreement.
(b)    Shareholders’ Representative Expense Fund. Promptly at the Closing, Parent shall cause to be deposited with the Shareholders’ Representative an aggregate amount equal to the Shareholders’ Representative Expense Fund to be held for the purpose of funding any reasonable expenses of the Shareholders’ Representative arising in connection with the administration of the Shareholders’ Representative’s duties in this Agreement and any agreements ancillary hereto after the Effective Time, as determined in the sole discretion of the Shareholders’ Representative.
8.3    Indemnification; Escrow Fund; Right of Setoff.
(a)    From and after the Closing Date (but subject to Section 8.1 and the limitations set forth in Section 8.3(d)), each Indemnified Party shall be defended and held harmless, severally and not jointly, by the Company Equityholders and shall be indemnified, severally and not jointly, by the Company Equityholders from and against any Losses which are suffered or incurred by any Indemnified Party or to which any Indemnified Party may otherwise become subject (regardless of whether or not such Losses relate to any Third-Party Claim) and which arise from or as a result of:
(i)    any inaccuracy in or breach of any representation or warranty of the Company contained in this Agreement or any certificate delivered by the Company pursuant to this Agreement;
(ii)    any failure by the Company to perform or comply with any agreement, obligation or covenant of the Company contained in this Agreement;
(iii)    (1) any Taxes of the Company with respect to any Pre-Closing Tax Period to the extent such Taxes were not included in the calculation of Net Closing Cash, (2) any Taxes for which the Company (or a predecessor thereof) is held liable under Treasury Regulations Section 1.1502-6 (or any similar provision of state, local or foreign law) by reason of such entity being included in any consolidated, affiliated, combined or unitary group at any time before the Closing Date to the extent such Taxes were not included in the calculation of Net Closing Cash, and (3) the Taxes of any Person (other than the Company) imposed on the

-71-





Company as a transferee or successor, by Contract or otherwise, in each case as a result of a transaction consummated before the Closing Date;
(iv)    any claim by any holder or former holder of Common Stock exercising dissenters’ rights or rights of appraisal in respect of such holder’s Dissenting Shares, together with all reasonable costs and expenses (including reasonable attorneys’ fees, costs and expenses) incurred by Parent in respect of such holder’s exercise;
(v)    any inaccuracy in the Closing Date Allocation Schedule, including to the extent any Company Equityholder is entitled to receive any amounts in connection with the Merger (in such Company Equityholder’s capacity as an Company Equityholder) in excess of the amounts indicated on the Closing Date Allocation Schedule; and
(vi)    fraud, intentional misrepresentation or willful misconduct on the part of the Company.
(b)    In the event any Indemnified Party shall suffer any Losses for which such Indemnified Party is entitled to indemnification under this Article VIII, subject to Section 8.3(d), such Indemnified Party shall be entitled to recover such Losses by obtaining the amount from the Escrow Fund equal in value to the aggregate amount of such Losses. Notwithstanding the forgoing, if an Indemnified Party is entitled to indemnification under this Article VIII as a result of any inaccuracy or breach of any representation or warranty set forth in Section 3.8(h)(i) (Intellectual Property) or of a Fundamental Representation (collectively, the “Special Claims”), Parent shall have the right to setoff (the “Right of Setoff”), on a dollar for dollar basis, the amount of Losses arising from such Special Claim against Milestone Payment Amounts or Revenue Sharing Amounts payable (but not any Milestone Payment Amounts or Revenue Sharing Amounts previously paid) to the Company Equityholders. Once a Special Claim is finally determined in accordance with this Agreement, if the Losses relating to such Special Claim are determined to be less than the amount setoff against the applicable Milestone Payment Amounts or Revenue Sharing Amounts, Parent shall pay to the Company Equityholders in accordance with the Closing Date Allocation Schedule the remaining amount of such Milestone Payment Amounts or Revenue Sharing Amounts via wire transfer of immediately available funds.
(c)    Notwithstanding anything to the contrary contained herein, the Escrow Fund shall not be available to compensate any of the Indemnified Parties for any Losses, and no Indemnified Party shall be entitled to recover from the Escrow Fund unless and until the Indemnified Parties have incurred Losses in excess of $100,000 in the aggregate (the “Deductible Amount”), in which event the Indemnified Parties shall, subject to the other limitations contained herein, be entitled to be indemnified only against the portion of such Losses in excess of the Deductible Amount. The Deductible Amount shall not apply to (i) any inaccuracy in or breach of any Fundamental Representations or (ii) the matters referenced in Sections 8.3(a)(ii) through 8.3(a)(vi).
(d)    Notwithstanding anything to the contrary contained herein: (i) any Losses recoverable from the Right of Setoff and the Escrow Fund hereunder shall be reduced in amount

-72-





by any insurance proceeds actually realized by any Indemnified Party that are directly attributable to such Losses (provided that the Indemnified Party shall not be required to litigate any dispute, or otherwise bring any claim, lawsuit or other proceeding to obtain such insurance proceeds); and (ii) no Losses (other than Losses from Third Party Claims) shall be recoverable from the Escrow Fund hereunder that constitute punitive or consequential damages, or any damages related to diminution in value.
(e)    All claims for recovery for any Loss or Losses from the Escrow Fund shall be made pursuant to and in accordance with, and be governed by the terms of, this Agreement and the Escrow Agreement.
8.4    Limitation on Remedies.
(a)    The Right of Setoff, where applicable, and recovery from the Escrow Fund shall be the sole and exclusive remedies of the Indemnified Parties under this Agreement or for any Losses incurred by any Indemnified Party (other than claims for injunctive relief and/or specific performance of covenants that require performance after the Closing), and the Indemnified Parties shall in all cases proceed against the Escrow Fund until it has been exhausted prior to exercising the Right of Setoff (provided that any amounts in the Escrow Fund subject to a claim by an Indemnified Party pursuant to Section 8.3 shall be considered exhausted for this purpose). Notwithstanding the foregoing, (i) liability for any Losses based on any inaccuracy in or breach of any Fundamental Representations or the matters referenced in Sections 3.8(h)(i) and 8.3(a)(ii) through 8.3(a)(vi) shall not be limited to the Right of Setoff and recovery from the Escrow Fund, and instead shall be limited to the aggregate amount of the Merger Consideration paid, or due and payable, under this Agreement, and (ii) a Company Equityholder’s liability for his, her or its own fraud, intentional misrepresentation or willful misconduct shall not be limited under this Article VIII. For the avoidance of doubt, in no event will any Company Equityholder be liable to the Indemnified Parties for any amounts in excess of the portion of the Merger Consideration actually received by, or in the case of the Escrow Fund and the Shareholders’ Representative Expense Fund, allocated to, such Company Equityholder (except in circumstances of fraud, intentional misrepresentation or willful misconduct by such Company Equityholder).
8.5    Shareholders’ Representative; Advisory Committee.
(a)    By virtue of the approval and adoption of this Agreement by the requisite consent of the Company Shareholders, each of the Company Equityholders shall be deemed to have agreed to appoint (i) Shareholder Representative Services LLC as its exclusive agent and attorney-in-fact (the “Shareholders’ Representative”) for and on behalf of the Company Equityholders to give and receive notices and communications; to authorize payment to any Indemnified Party from the Escrow Fund in satisfaction of claims by any Indemnified Party; to object to such payments; to challenge any determination of Parent or the Surviving Corporation with respect to amounts alleged as due as Milestone Payment Amounts or Revenue Sharing Amounts; to agree to, negotiate, enter into settlements and compromises of, and demand arbitration and comply with orders of courts and awards of arbitrators with respect to claims; to assert, negotiate, enter into settlements and compromises of, and demand arbitration and comply

-73-





with orders of courts and awards of arbitrators with respect to, any claim by any Indemnified Party against any Company Equityholder or by any such Company Equityholder against any Indemnified Party, or any claim against Parent or the Surviving Corporation with respect to any alleged Milestone Payment Amount or Revenue Sharing Amount; or any dispute between any Indemnified Party and any such Company Equityholder, or between Parent or the Surviving Corporation and any Company Equityholder with respect to any alleged Milestone Payment Amount or Revenue Sharing Amount, in each case relating to this Agreement or the Transactions, and to take all other actions that are either (1) necessary or appropriate in the judgment of the Shareholders’ Representative for the accomplishment of the foregoing or (2) specifically mandated by the terms of this Agreement or the Escrow Agreement; and (ii) Robert Etches and Robert Cochran as the members of an advisory committee (the “Advisory Committee”) to exercise discretionary decision-making authority over the actions of the Shareholders’ Representative with respect to its obligations under this Agreement. Notwithstanding the foregoing, the Shareholders’ Representative shall have no obligation to act on behalf of the Company Equityholders, except as expressly provided herein, in the Escrow Agreement and in the SRS Engagement Letter, and for purposes of clarity, there are no obligations of the Shareholders’ Representative in any ancillary agreement, schedule, exhibit or the Company Disclosure Letter. Such agency may be changed by the Company Equityholders with the right to a majority in interest of the Escrow Fund from time to time. Notwithstanding the foregoing, the Shareholders’ Representative or any member of the Advisory Committee may resign at any time by providing written notice of intent to resign to the Company Equityholders, which resignation shall be effective upon the earlier of (1) thirty (30) calendar days following delivery of such written notice or (2) the appointment of a successor by the holders of a majority in interest of the Escrow Fund. The immunities and rights to indemnification shall survive the resignation or removal of the Shareholders’ Representative, any member of the Advisory Committee and the Closing and/or any termination of this Agreement, the Escrow Agreement and the SRS Engagement Letter. No bond shall be required of the Shareholders’ Representative or the Advisory Committee. Further rights, responsibilities and limitations of the Shareholders’ Representative and the Advisory Committee shall be as set forth in the SRS Engagement Letter.
(b)    The Shareholders’ Representative shall be entitled to: (i) rely upon the Closing Date Allocation Schedule, (ii) rely upon any signature reasonably believed by it to be genuine, and (iii) reasonably assume that a signatory has proper authorization to sign on behalf of the applicable Company Equityholder or other party. A decision, act, consent or instruction of the Shareholders’ Representative under this Agreement, the Escrow Agreement or the SRS Engagement Letter, including an amendment, extension or waiver of this Agreement pursuant to Sections 9.4 or 9.5 hereof, shall constitute a decision of the Company Equityholders and shall be final, binding and conclusive upon the Company Equityholders and such Company Equityholder’s successors as if expressly confirmed and ratified in writing by such Company Equityholder. The powers, immunities and rights to indemnification granted to the Shareholders’ Representative and the Advisory Committee hereunder: (i) are coupled with an interest and shall be irrevocable and survive the death, incompetence, bankruptcy or liquidation of any Company Equityholder and shall be binding on any successor thereto, and (ii) shall survive the delivery of an assignment by any Company Equityholder of the whole or any fraction of his, her or its interest in the Escrow Fund.

-74-





(c)    The Shareholders’ Representative shall be entitled to withdraw amounts from the Shareholders’ Representative Expense Fund as are reasonably necessary for the performance of the Shareholders’ Representative’s duties under this Section 8.5, including, without limitation, amounts necessary to retain and compensate representatives of the Shareholders’ Representative, including, without limitation, such legal, financial and accounting advisors as the Shareholders’ Representative deems necessary and proper, in each case at the sole discretion of the Shareholders’ Representative Agent. The Company Equityholders will not receive any interest or earnings on the Shareholders’ Representative Expense Fund and irrevocably transfer and assign to the Shareholders’ Representative any ownership right that they may otherwise have had in any such interest or earnings. The Shareholders’ Representative will not be liable for any loss of principal of the Shareholders’ Representative Expense Fund other than as a result of its gross negligence or willful misconduct. The Shareholders’ Representative will hold these funds separate from its corporate funds, will not use these funds for its operating expenses or any other corporate purposes and will not voluntarily make these funds available to its creditors in the event of bankruptcy. As soon as practicable following the completion of the Shareholders’ Representative’s responsibilities, the Shareholders’ Representative will deliver any amounts remaining in the Shareholders’ Representative Expense Fund (the “Remaining Expense Fund”) to Parent for further distribution to the Company Equityholders according to the following procedures: (1) Parent shall distribute or cause to be distributed to the Company Shareholders their proportionate share of an amount equal to (A) the Remaining Expense Fund, less (B) the amounts payable to the Company Optionholders in respect of the Remaining Expense Fund, less (C) the amount of Taxes payable by Parent, the Company, the Surviving Corporation or their Subsidiaries with respect to the amounts payable to the Company Optionholders in respect of the Remaining Expense Fund, and (2) Parent shall pay to the Surviving Corporation, and the Surviving Corporation shall pay to the Company Optionholders the proportionate amounts payable to them in respect of the Remaining Expense Fund (after deduction of the amount in clause (C) above) through the Surviving Corporation’s payroll, subject to all applicable withholding Taxes; provided, that Parent shall be under no obligation to pay any amounts under this Section 8.5(c) until it has received an updated Closing Date Allocation Schedule from the Shareholders’ Representative setting forth the proportion (expressed as a percentage) of such amounts that each Company Equityholder is entitled to receive from such payments. For Tax purposes, the Shareholders’ Representative Expense Fund shall be treated as having been received and voluntarily set aside by the Company Equityholders at the time of Closing.
(d)    Neither the Shareholders’ Representative nor the Advisory Committee (in its capacity as such) will incur any liability of any kind with respect to any action or omission by the Shareholders’ Representative or the Advisory Committee in connection with the Shareholders’ Representative’s or the Advisory Committee’s services pursuant to this Agreement and any agreements ancillary hereto, except in the event of liability directly resulting from the Shareholders’ Representative’s or the Advisory Committee’s gross negligence or willful misconduct; provided that the foregoing shall not limit the Shareholders’ Representative’s right to indemnification from the members of the Advisory Committee in their capacity as Company Equityholders. Neither the Shareholders’ Representative nor the Advisory Committee shall be liable to the Company Equityholders for any action or omission pursuant to the advice of

-75-





counsel. The Company Equityholders will indemnify, defend and hold harmless the Shareholders’ Representative and the Advisory Committee from and against any and all losses, liabilities, damages, claims, penalties, fines, forfeitures, actions, fees, costs and expenses (including the fees and expenses of counsel and experts and their staffs and all expense of document location, duplication and shipment) (collectively, “Representative Losses”) arising out of or in connection with the Shareholders’ Representative’s execution and performance of this Agreement, the Advisory Committee’s performance of this Agreement and execution and performance of the SRS Engagement Letter, and any agreements ancillary hereto, in each case as such Representative Loss is suffered or incurred; provided, that in the event that any such Representative Loss is finally adjudicated to have been directly caused by the gross negligence or willful misconduct of the Shareholders’ Representative or the Advisory Committee, the Shareholders’ Representative or the Advisory Committee, as the case may be, will reimburse the Company Equityholders the amount of such indemnified Representative Loss to the extent attributable to such gross negligence or willful misconduct. If not paid directly to the Shareholders’ Representative or the Advisory Committee by the Company Equityholders, any such Representative Losses may be recovered by the Shareholders’ Representative and the Advisory Committee from (i) the funds in the Shareholders’ Representative Expense Fund, (ii) the amounts in the Escrow Fund at such time as remaining amounts would otherwise be distributable to the Company Equityholders, and (iii) from any Milestone Payment Amount at such time as any such amounts would otherwise be distributable to the Company Equityholders; provided, that while this section allows the Shareholders’ Representative and the Advisory Committee to be paid from the aforementioned sources of funds, this does not relieve the Company Equityholders from their obligation to promptly pay such Representative Losses as they are suffered or incurred, nor does it prevent the Shareholders’ Representative or the Advisory Committee from seeking any remedies available to it at law or otherwise. In no event will the Shareholders’ Representative or the Advisory Committee (in its capacity as such) be required to advance its own funds on behalf of the Company Equityholders or otherwise. Notwithstanding anything in this Agreement to the contrary, any restrictions or limitations on liability or indemnification obligations of the Company Equityholders set forth elsewhere in this Agreement are not intended to be applicable to the indemnities provided to the Shareholders’ Representative and the Advisory Committee under this Section. The foregoing indemnities will survive the Closing, the resignation or removal of the Shareholders’ Representative or the Advisory Committee or the termination of this Agreement.
8.6    Third-Party Claims
(a)    In the event that an Indemnified Party becomes aware of a third-party claim (a “Third-Party Claim”) that the Indemnified Party reasonably believes may result in a demand against the Escrow Fund or for other indemnification pursuant to this Article VIII, Parent shall promptly notify the Shareholders’ Representative and the Escrow Agent, if the Escrow Fund has not ceased to exist, of such claim (a “Claim Notice”); provided, however, that no delay or failure on the part of an Indemnified Party in delivering any Claim Notice shall relieve the Company Equityholders from any liability hereunder except and to the extent the Company Equityholders have been actually prejudiced by such delay or failure.

(b)    Parent may, at its election, undertake and conduct the defense of such Third-Party Claim (except to the extent such Claim may be controlled by the Shareholders’ Representative pursuant to Section 6.6(a)(ii)) upon written notice of such election to the Shareholders’ Representative within thirty (30) days after delivery of the Claim Notice. The Shareholders’ Representative shall be entitled to participate in, but not to determine or conduct, the defense of such Third-Party Claim, unless such participation would affect any privilege of Parent in respect of such Third-Party Claim; provided, however, that Parent shall have the right in its reasonable discretion to settle any such claim; provided, further, that except with the prior written consent of the Shareholders’ Representative (which consent shall not be unreasonably withheld, delayed or conditioned), no settlement of any such Third-Party Claim with third-party claimants shall be determinative of any Losses relating to such matter. Notwithstanding the foregoing, the Shareholders’ Representative shall have the right to receive copies of all pleadings, notices and communications with respect to the Third-Party Claim to the extent that receipt of such documents by the Shareholders’ Representative does not affect any privilege relating to the Indemnified Party.
(c)    If Parent does not so elect to undertake and conduct the defense of such Third-Party Claim, the Shareholders’ Representative may undertake the defense of and use all reasonable efforts to defend such claim and shall consult with Parent regarding the strategy for defense of such claim, including with respect to the Shareholders’ Representative choice of legal counsel; provided, however, that the Shareholders’ Representative shall have the right in their reasonable discretion to settle any such claim; provided, further, that except with the prior written consent of Parent (which consent shall not be unreasonably withheld, delayed or conditioned), no settlement of any such Third-Party Claim with third-party claimants shall be determinative of any Losses relating to such matter. Notwithstanding the foregoing, in the event that (i) the control of the defense by the Shareholders’ Representative would be inappropriate due to a conflict of interest or because the Indemnified Party has been advised by counsel that in such counsel’s opinion it has claims or defenses that are unavailable to the Company Equityholder which the Shareholders’ Representative is unable or unwilling to assert, (ii) such Third-Party Claim (or the facts or allegations related to such Third-Party Claim) involves criminal allegations or seeks equitable or injunctive relief, or (iii) the Shareholders’ Representative fail at any time to conduct the defense of such proceeding, claim or demand in a reasonably active and diligent manner, then Parent shall have the right to assume the control of such defense. Until the Shareholders’ Representative assumes the defense of any such Third-Party Claim, the Indemnified Party may defend against such Third-Party Claim in any manner the Indemnified Party reasonably deems appropriate at cost and expense of the Company Equityholder if the Company Equityholder are liable for indemnification hereunder. Notwithstanding any other provision of this Article VIII, the Shareholders’ Representative shall not enter into any compromise, settlement agreement or consent decree with respect to any such Third-Party Claim without the prior written consent of Parent (which consent shall not be unreasonably withheld, delayed or conditioned) unless such compromise, settlement agreement or consent decree (x) provides solely for the payment of money in an amount that is less than the amount of the Escrow Amount then remaining in the Escrow Fund, (y) contains a complete and unconditional release by the third party asserting the Third-Party Claim of the Indemnified Party and (z) does

-77-





not contain any direct or indirect requirements upon or provisions for or impose any obligations on the Indemnified Party.
(d)    The party controlling the defense of a Third-Party Claim (the “Controlling Party”) shall (i) keep the other party (the “Non-Controlling Party”) advised of the status of such claim and the defense thereof (including all material developments and events relating thereto) and shall consider in good faith recommendations made by the Non-Controlling Party with respect thereto and (ii) make available to the Non-Controlling Party any documents or materials in its possession or control that may be necessary to understand the defense of such claim (subject to protection of the attorney-client privilege). If requested by the Controlling Party, the Non-Controlling Party shall furnish the Controlling Party with such information as it may have with respect to such Third-Party Claim (including copies of any summons, complaints or other pleadings which may have been served on such party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and shall otherwise reasonably cooperate with and assist the Controlling Party in the defense of such Third-Party Claim.
8.7    Notice of Indemnity Claims Other than Third-Party Claims.
(a)    In order to seek indemnification under this Article VIII other than with respect to a Third-Party Claim, the applicable Indemnified Party shall deliver a written demand (an “Indemnification Demand”) to the Shareholders’ Representative and to the Escrow Agent, if the Escrow Fund has not ceased to exist. The Indemnification Demand shall contain (i) a description and the amount of any Losses incurred or reasonably expected to be incurred by the Indemnified Party, (ii) a statement that the Indemnified Party is entitled to indemnification under Section 8.3(a) for such Losses and a reasonable explanation of the basis therefor and (iii) a demand for payment in the amount of such Losses.
(b)    The Shareholders’ Representative may object to any liability claim set forth in an Indemnification Demand by delivering written notice to Parent of the Shareholders’ Representative’s objection (an “Indemnification Dispute Notice”). Such Indemnification Dispute Notice will describe the grounds (to the extent known) for such objection in reasonable detail. If the Shareholders’ Representative fail to deliver an Indemnification Dispute Notice to the Indemnified Party within thirty (30) days following receipt of an Indemnification Demand from a Indemnified Party that it disputes the indemnity claimed therein, the indemnity claim set forth in the Indemnification Demand shall be conclusively deemed a liability to be indemnified under this Article VIII, and such Indemnified Party shall, subject to the limitations contained in this Article VIII, be indemnified for the amount of the Losses stated in such Indemnification Demand on demand. If an Indemnification Dispute Notice is delivered, the parties shall thereafter comply with the following dispute resolution provisions:
(i)    The Shareholders’ Representative and the Indemnified Party shall attempt to resolve such dispute promptly by negotiation in good faith. Each such party shall give the other party involved written notice of any dispute not so resolved within ten (10) days following delivery of an Indemnification Dispute Notice. Within five (5) days following delivery of such notice, the party receiving notice shall submit to the other a written response

-78-





thereto. The notice and response shall include the name and title of the Person who will represent the Indemnified Party and any other Person who will accompany that Person, in the case of the Indemnified Party, or the name of the agent, if other than Shareholders’ Representative, who will represent the Company Equityholders and any other Person who will accompany that agent, in the case of the Shareholders’ Representative.
(ii)    Within ten (10) days following delivery of the notice pursuant to Section 8.7(b)(i), the designated officer of the Indemnified Party and the Shareholders’ Representative or other designated agent of the Company Equityholders shall meet at a mutually agreed time and place, and thereafter, as often as they reasonably deem necessary, to attempt to resolve the dispute. All negotiations conducted pursuant to this Section 8.7(b) (and any of the parties’ submissions in contemplation thereof) shall be kept confidential by the parties.
(c)    In the event the Shareholders’ Representative and the Indemnified Party are unable to resolve any dispute identified in an Indemnification Dispute Notice in accordance with provisions (i) and (ii) of this Section 8.7(b) within thirty (30) days after delivery of any Indemnification Dispute Notice, either the Indemnified Party or the Shareholders’ Representative may seek to resolve the matter through litigation brought in accordance with Section 10.8.
8.8    No Circular Recovery. After the Closing, and except as provided for in Section 6.14, and other than with respect to fraud, intentional misrepresentation or willful misconduct on the part of Parent or the Surviving Corporation, the Company Equityholders shall not have any right of contribution, right of indemnity or other right or remedy against Parent or the Surviving Corporation, or any of their directors, officers or employees, for any breach of any representation, warranty, covenant or agreement of the Company.
8.9    Determination of Indemnifiable Losses. For the purpose of determining the amount of the Losses resulting from a breach or inaccuracy of a representation or warranty (but not for the purpose of determining the existence of such breach or inaccuracy), any “material,” “materiality” or “Material Adverse Effect” qualifiers or words of similar import contained in such representation or warranty giving rise to the claim of indemnity hereunder shall in each case be disregarded and without effect (as if such standard or qualification were deleted from such representation or warranty).
8.10    Tax Consequences of Indemnification Payments.  Any payments made to an Indemnified Party pursuant to any indemnification obligations under this Article VIII will be treated as adjustments to the purchase price for all Tax purposes, the parties shall file their respective Tax Returns accordingly and such agreed treatment will govern for purposes of this Agreement, unless otherwise required by law.
ARTICLE IX.

-79-

(b)    by either the Company or Parent if the Merger shall not have been consummated by October 31, 2017 (the “End Date”); provided, that the right to terminate this Agreement under this Section 9.1(b) shall not be available to any party whose action or failure to act (including the failure to act in compliance with Section 6.4) has been a principal cause of or resulted in the failure of the Merger to occur on or before such date and such action or failure to act constitutes a breach of this Agreement;
(c)    by either the Company or Parent if a Governmental Entity shall have issued an order, decree or ruling or taken any other action (including the failure to have taken an action), in any case having the effect of (i) permanently restraining, enjoining or otherwise prohibiting the Merger, (ii) prohibiting Parent’s or the Company’s ownership or operation of any portion of the business of the Company, or (iii) compelling Parent or any of its Affiliates or the Company to dispose of or hold separate, as a result of the Merger, any portion of the business or assets of Parent or any of its Affiliates or the Company, which order, decree, ruling or other action is final and nonappealable;
(d)    by the Company upon a breach of any representation, warranty, covenant or agreement on the part of Parent or Merger Sub set forth in this Agreement, or if any representation or warranty of Parent or Merger Sub shall have become untrue, in either case such that the conditions set forth in Sections 7.2(a) or 7.2(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become untrue, provided that the Company may not terminate this Agreement under this Section 9.1(d) prior to the later of the End Date and thirty (30) days following the receipt of written notice by Parent from the Company of such breach (it being understood that the Company may not terminate this Agreement pursuant to this Section 9.1(d) if the Company is in material breach of this Agreement or if such breach by Parent is cured so that such conditions would then be satisfied);
(e)    by Parent, upon a breach of any representation, warranty, covenant or agreement on the part of the Company set forth in this Agreement, or if any representation or warranty of the Company shall have become untrue, in either case such that the conditions set forth in Sections 7.3(a) or 7.3(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become untrue, provided that Parent may not terminate this Agreement under this Section 9.1(e) prior to the later of the End Date and thirty (30) days following the receipt of written notice by the Company from Parent of such breach (it being understood that Parent may not terminate this Agreement pursuant to this Section 9.1(e) if Parent is in material breach of this Agreement or if such breach by the Company is cured so that such conditions would then be satisfied); or
9.2    Notice of Termination; Effect of Termination. Any termination of this Agreement under Section 9.1 will be effective immediately upon the delivery of a valid written notice of the terminating party to the other party hereto (taking into consideration any cure periods provided in Section 9.1). In the event of the termination of this Agreement as provided in Section 9.1, this Agreement shall be of no further force or effect, except (a) as set forth in Section 6.2(a), this

-80-





Section 9.2, Section 9.3 and Article X, each of which shall survive the termination of this Agreement and (b) nothing herein shall relieve any party to this Agreement from liability for any willful breach of this Agreement. No termination of this Agreement shall affect the obligations of the parties contained in the Confidentiality Agreement, all of which obligations shall survive termination of this Agreement in accordance with their terms.
9.3    Fees and Expenses. Except as otherwise set forth in this Agreement, all fees and expenses incurred in connection with this Agreement and the Transactions, including fees and expenses of financial advisors, financial sponsors, legal counsel and other advisors (“Transaction Expenses”), shall be paid by the party incurring such expenses whether or not the Merger is consummated. For the avoidance of doubt, the cost of an audit of the Surviving Corporation’s financial statements relating to any period prior to the Closing Date, if any, shall be paid by the Parent.
9.4    Amendment. Subject to applicable Legal Requirements, this Agreement may be amended by the parties hereto, by action duly authorized by the parties, at any time before or after approval and adoption of this Agreement by the shareholders of the Company, provided that no amendment shall be made which requires further approval by the shareholders of the Company without such further shareholder approval. This Agreement may not be amended except by execution of an instrument in writing signed on behalf of each of Parent, Merger Sub, Shareholders’ Representative and the Company.
9.5    Extension; Waiver. At any time prior to the Effective Time either party hereto, by action duly authorized by such party, may, to the extent legally allowed: (a) extend the time for the performance of any of the obligations or other acts of the other parties hereto; (b) waive any inaccuracies in the representations and warranties made to such party contained herein or in any document delivered pursuant hereto; and (c) waive compliance with any of the agreements or conditions for the benefit of such party contained herein.

Delay in exercising any right under this Agreement shall not constitute a waiver of such right.

For purposes of this Agreement; (i) the words “include,” “includes” and “including,” when used herein, shall be deemed in each case to be followed by the words “without limitation”; (ii) “hereof”, “hereto”, “hereby”, “herein” and “hereunder” and words of similar import when used in this Agreement refer to this Agreement as a whole and not to any particular provision of this Agreement; (iii) “date hereof” refers to the date of this Agreement; (iv) “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase does not mean simply “if”; (v) definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms; (vi) references to an agreement or instrument mean such agreement or instrument as from time to time amended, modified or supplemented; (vii) references to a Person are also to its permitted successors and assigns; (viii) words importing the masculine gender include the feminine or neuter and, in each case, vice versa; and (ix) references to a law or Legal Requirement include any amendment or modification to such law or Legal Requirement and any rules or regulations issued thereunder, if such amendment or modification, or such rule or regulation is effective, on or before the date on which the compliance with such law or Legal Requirement is at issue. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. When reference is made herein to “the business of” an entity, such reference shall be deemed to include the business of such entity and its Subsidiaries, taken as a whole. The Company Disclosure Letter shall be arranged in sections and subsections corresponding to the numbered and lettered sections and subsections contained in this Agreement. An exception or disclosure made in the Company Disclosure Letter with regard to a representation of the Company in any section or subsection of the Company Disclosure Letter shall qualify only the corresponding section or subsection of Article III.
10.3    Counterparts. This Agreement may be executed in two (2) or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other party, it being understood that all parties need not sign the same counterpart.
10.4    Entire Agreement; Third-Party Beneficiaries. This Agreement and the documents and instruments and other agreements among the parties hereto as contemplated by or referred to herein, including the Company Disclosure Letter, the Escrow Agreement and the certificates delivered by the Company in connection herewith (a) constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof, it being understood that the Confidentiality Agreement shall continue in full force and effect until the Closing and shall survive any termination of this Agreement and (b) are not intended to confer upon any other Person any rights or remedies hereunder and no Person is or shall be deemed to be a third party beneficiary hereunder.
10.5    Severability. In the event that any provision of this Agreement or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and the application of such provision to other Persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto. The parties further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the greatest extent possible, the economic, business and other purposes of such void or unenforceable provision.
10.6    Other Remedies. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will 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 will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Accordingly, each of the parties agrees that, without posting bond or other undertaking, the other parties will be entitled to seek an injunction or injunctions to prevent breaches or violations of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions hereof in any proceeding instituted in any court of the United States or any state thereof having jurisdiction over the parties and the matter in the state courts in the State of California (or, in the case of any claim as to which the federal courts have exclusive subject matter jurisdiction, the United States District Court for the Southern District of California, located in the City of San Diego), this being in addition to any other remedy to which it may be entitled, at law or in equity. Each party further agrees that, in the event of any action for specific performance in respect of such breach or violation, it will not assert the defense that a remedy at law would be adequate.
10.7    Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of California regardless of the laws that might otherwise govern under applicable principles of conflicts of law thereof.
10.8    Consent to Jurisdiction. Except with respect to the disputes contemplated in Section 2.12(d)(ii) and subject to the provisions of Section 2.9(e), the parties (a) hereby irrevocably and unconditionally submit to the jurisdiction of the state courts of California and to the jurisdiction of the United States District Court for the Southern District of California, in each case located in the City of San Diego, for the purpose of any Action arising out of or based upon this Agreement, (b) agree not to commence any suit, action or other proceeding arising out of or based upon this Agreement except in the state courts of California or the United States District Court for the Southern District of California in each case located in the City of San Diego, (c) hereby waive, and agree not to assert, by way of motion, as a defense, or otherwise, in any Action, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court. Each of the parties hereto agrees that a final judgment in any such action or proceeding may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 10.1. Nothing in this Agreement shall affect the right of any party to this Agreement to serve process in any other manner permitted by law.
10.9    Waiver of Jury Trial. Each of the parties irrevocably waives the right to trial by jury in connection with any matter based upon or arising out of this Agreement, the Escrow Agreement or the Transactions contemplated hereby and thereby.
10.10    Rules of Construction. The parties hereto agree that they have been represented by counsel during the negotiation and execution of this Agreement and, therefore, waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.
10.11    Assignment. No party may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written approval of the other parties. Any purported assignment in violation of this Section 10.11 shall be void. Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns. Notwithstanding the foregoing, Parent may sell, transfer or assign its rights under this Agreement to any third party, as part of a sale or transfer of substantially all of Parent’s assets or of the assets of the Surviving Corporation; provided that such third party agrees in writing to be bound by the terms and conditions of this Agreement.
10.12    No Waiver. No failure or delay on the part of any party hereto in the exercise of any right hereunder will impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor will any single or partial exercise of any such right preclude other or further exercise thereof or of any other right.
10.13    Waiver of Conflicts. Each of the parties hereto acknowledges and agrees, on its own behalf and on behalf of its directors, stockholders, partners, officers, employees and Affiliates that the Company, and not any of the individual Company Equityholders, is the client of VLP Law Group LLP and Spiegelman Life Sciences PC (collectively, the “Firms”). After the Closing, it is possible that either or both of the Firms will represent the Company Equityholders, the Shareholders’ Representative, the Advisory Committee and their respective Affiliates (individually and collectively, the “Seller Group”) in connection with the transactions contemplated herein or in the Escrow Agreement, the Escrow Fund and any claims made thereunder pursuant to this Agreement or the Escrow Agreement. Parent and the Company hereby agree that the Firms (or any successors) may represent the Seller Group (and/or any subset thereof) after the Closing in connection with issues that may arise under this Agreement or the Escrow Agreement, the administration of the Escrow Fund and any claims that may be made thereunder pursuant to this Agreement or the Escrow Agreement. After the Closing, the Firms (or any successors) may serve as counsel to all or a portion of the Seller Group or any director, stockholder, partner, officer, employee, representative or Affiliate of the Seller Group, in connection with any litigation, claim or obligation arising out of or relating to this Agreement, the Escrow Agreement or the transactions contemplated hereby or thereby. Each of the parties hereto consents thereto, and waives any conflict of interest arising from such representation.
