No interference, inter partes review, post-grant review, opposition, reissue, reexamination or other Legal Proceeding is or has been pending or, to the Knowledge of the Company, threatened in writing, in which the ownership, scope, validity or enforceability of any Owned Company Patent is being, has been or would be contested or challenged. To the Knowledge of the Company, no interference, inter partes review, post-grant review, opposition, reissue, reexamination or other Legal Proceeding is or has been pending or threatened in writing, in which the ownership, scope, validity or enforceability of any Company Intellectual Property other than Owned Company Patent is being, has been or would be contested or challenged.

To the Knowledge of the Company, there does not exist any material fact that the Company reasonably believes would (i) preclude the issuance of any patents from patent applications included in the Company Patents, (ii) render any (now- or hereafter-) issued patents included in the Company Patents invalid or unenforceable, or (iii) cause any claims included in the Company Patents to be materially narrowed.

g.The Company has taken all commercially reasonable steps and precautions to protect and maintain the confidentiality of all confidential know-how, trade secrets and other confidential items included within the Company Intellectual Property and otherwise to maintain and protect the value of all such confidential know-how, trade secrets and other confidential items.

j.The Company has never disclosed confidential information or other confidential items (including any tangible embodiment) included within Company Intellectual Property to a third party without having the recipient thereof execute a written agreement regarding the non-disclosure and non-use (other than research uses only) thereof, other than the disclosure of patent rights after the filing of any application in respect thereof.

k.Other than pursuant to the express terms of the Minotaur License and the Scripps License, there are no royalties, fees or other amounts payable by the Company to any Person by reason of the ownership (other than customary fees and amounts payable for filing, prosecuting and maintaining patents and patent applications), use, sale or disposition of Company Intellectual Property (or any tangible embodiment thereof), and there are no obligations to pay any such royalties, fees or other amounts that are currently payable or past due.

l.To the Knowledge of the Company, no Company Intellectual Property has been infringed or misappropriated by any third party.

m.The Company has never entered into any Contract to indemnify any other person against any charge of infringement of any Intellectual Property.

n.All current and former managers, officers and employees of the Company (including “leased employees”) have executed and delivered to the Company an agreement regarding the protection of proprietary information and assigning to the Company (and requiring the assignment to the Company of) any Intellectual Property arising from services performed for the Company by such persons, the form of which has been provided to Parent.

o.No university, Governmental Entity or other organization sponsored research and development conducted by the Company in such a way as to have any claim of right to or ownership of or other Encumbrance on any Owned Intellectual Property. No research and development conducted by the Company was performed by a graduate student or employee of any Governmental Entity.

22

p.The Transactions will not, with or without notice or lapse of time, result in, or give any other Person the right or option to cause or declare: (i) a loss of, or Encumbrance on, any Company Intellectual Property; (ii) the release, disclosure or delivery of any Company Intellectual Property by or to any escrow agent or other Person; or (iii) the grant, assignment or transfer to any other Person of any license or other right or interest under, to or in any of the Company Intellectual Property.

Section 4.14 Assets. The Company has good and valid title to all of its assets (tangible or intangible), free and clear of any Encumbrances, other than Permitted Encumbrances. (It is understood that for in-licensed intangible assets, “good and valid title” to the asset shall be understood to mean good and valid title to the in-license agreement.) There is no agreement or arrangement for any Person to provide (or “lease”) equipment or other personal property to or for the use of the Company, except for agreements or arrangements which the Company and the counterparty thereto have agreed are being wholly terminated (without liability to the Company) as of no later than the Closing.

Section 4.16 Insurance. A statement delivered by the Company to Parent before the date hereof, and so designated, sets forth, as of the date of this Agreement, a complete and accurate list of all policies or binders of insurance covering the Company, in each case held by the Company or any other Person (the “Insurance Policies”), setting forth, in respect of each such Insurance Policy: (a) the policy number; (b) the insurer and the named insured(s); (c) policy limits and deductibles; (d) the dates of premiums or payments due thereunder; and (e) the expiration date. Each Insurance Policy is in full force and effect. To the Knowledge of the Company, there have been no gaps in insurance coverage that could expose the Company to uninsured material liability for events that occurred before the date of this Agreement. There is no material claim pending under any Insurance Policy as to which coverage has been questioned, denied or disputed by the underwriters of such Insurance Policy. All premiums due and payable to date under all Insurance Policies have been paid and the Company is otherwise in compliance in all material respects with the terms of such policies and Contracts.

Section 4.17 Certain Business Relationships with Affiliates. No event has occurred, and, other than entry into the Minotaur License and the Minotaur Services Agreement, there has been no transaction, or series of similar transactions, agreements, arrangements or understandings to which the Company is a party, of the sort which, if the Company were a reporting company under the Exchange Act, would be required heretofore or ultimately to be reported pursuant to Item 404 of Regulation S-K promulgated by the SEC.

c.Notwithstanding the foregoing, no Member shall be in breach of this Section 6.5 as a result of any disclosure of Company Confidential Information that is required by applicable Legal Requirements or that is required by any Governmental Entity or under any subpoena, civil investigative demand or other similar process by a court of competent jurisdiction having jurisdiction over such Member; provided, however, that the applicable Member shall give advance written notice of such compelled disclosure to Parent, and shall cooperate with Parent in connection with any efforts to prevent or limit the scope of such disclosure; and provided further, that the applicable Member shall disclose no larger portion of such Company Confidential Information than that which is legally required to be disclosed.

Section 6.6 General Release.

Section 1542 of the California Civil Code reads as follows:

28

“A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS THAT THE CREDITOR OR RELEASING PARTY DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, AND THAT IF KNOWN BY HIM OR HER, WOULD HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR OR RELEASED PARTY.”

Notwithstanding the provisions of Section 1542 of the California Civil Code or any similar Legal Requirement or common law principle in any applicable jurisdiction, and for the purpose of implementing a full and complete release and discharge of the Released Parties, each Member, on behalf of himself, herself or itself and each Releasing Party, expressly acknowledges that the foregoing release is intended to include in its effect all claims which any Member or any Releasing Party does not know or suspect to exist in his, her or its favor against any of the Released Parties (including unknown and contingent claims), and that the foregoing release expressly contemplates the extinguishment of all such claims (except to the extent expressly set forth herein).

c.Each Member, on behalf of himself, herself or itself and each Releasing Party, acknowledges that he, she or it may hereafter discover facts in addition to or different from those which he, she or it now knows or believes to be true with respect to the subject matter of the Released Claims, but each Member, on behalf of himself, herself or itself and each Releasing Party, intends to and, by operation of this Agreement shall have, fully, finally and forever settled and released any and all Released Claims without regard to the subsequent discovery of existence of such different or additional facts.

d.Each Member, on behalf of himself, herself or itself and each Releasing Party, represents, warrants, covenants and agrees that such Releasing Party has not assigned or transferred and will not assign or transfer any Released Claim or possible Released Claim against any Released Party. Each Member, on behalf of himself, herself or itself and each Releasing Party, agrees to indemnify and hold the Released Parties harmless from any Losses or costs arising as a result of any such assignment or transfer by such Member.

e.Each Member, on behalf of himself, herself or itself and each Releasing Party, covenants and agrees not to, and agrees to cause his, her or its respective Affiliates not to, whether in his, her or its own capacity, as successor, by reason of assignment or otherwise, assert, commence, institute or join in, or assist or encourage any third party in asserting, commencing, instituting or joining in, any Legal Proceeding of any kind whatsoever, in law or equity, in each case against the Released Parties, or any of them, with respect to any Released Claims.

Section 6.7 Vaughn Smider Covenant Not to Compete.

a.For a period commencing on the Closing Date and ending on the fourth anniversary of the date of this Agreement (the “Restricted Period”), Vaughn Smider (the “Restricted Person”) shall not, nor shall he permit any of his Affiliates to, directly or indirectly: (i) engage in or assist others in engaging (whether through employment, consultation, advisory services, representation on a board of directors or other similar governing body or by any financial or other investment) in the Restricted Business in the Territory; (ii) have an interest in any Person that engages directly or indirectly in the Restricted Business in the Territory in any capacity, including as a partner, stockholder, manager, member, employee, principal, agent, trustee or consultant; or (iii) intentionally interfere in any material respect with the business relationships involving the Restricted Business (whether formed prior to or after the date of this Agreement) between the Surviving Company or Parent and any customer, supplier, licensee, licensor, client or distributor of the Surviving Company or Parent. Notwithstanding the foregoing, the Restricted Person may own, directly or indirectly, solely as an investment, securities of any Person traded on any national securities exchange if the Restricted Person is not a controlling Person of, or a member of a group which controls, such Person and does not, directly or indirectly, own 2% or more of any class of securities of such Person. For the avoidance of doubt, the Restricted Person may engage in the Restricted Business on behalf of Minotaur, solely to the extent that such engagement is necessary for and in compliance with the terms of any Contract entered into between the Surviving Company or Parent and Minotaur.

b.During the Restricted Period, the Restricted Person shall not, nor shall he permit any of his Affiliates to, directly or indirectly, solicit or entice, or attempt to solicit or entice, any customers, suppliers, vendors, licensees, licensors, clients or distributors of the Company or Parent or potential customers, suppliers, vendors, licensees, licensors, clients or distributors of the Company for purposes of diverting their business or services, to the extent relating to the Restricted Business, from the Surviving Company or Parent, respectively.

c.If the Restricted Person breaches, or threatens to commit a breach of, any of the provisions of this Section 6.7, Parent and the Surviving Company shall have the following rights and remedies not subject to any limitations under Article 7, each of which rights and remedies shall be independent of the others and severally enforceable, and each of which is in addition to, and not in lieu of, any other rights and remedies available to Parent or the Surviving Company under law or in equity:

i.the right and remedy to have such provision specifically enforced by any arbitration forum or court having jurisdiction (and with any requirement for posting a bond or other security in connection therewith being hereby waived by the Restricted Person), it being acknowledged and agreed that any such breach or threatened breach may cause irreparable injury to each of Parent and the Surviving Company and that money damages may not provide an adequate remedy to Parent and the Surviving Company; and

ii.the right and remedy to recover from the Restricted Person all monetary damages suffered by Parent or the Surviving Company, as the case may be, as the result of any acts or omissions constituting a breach of this Section 6.7.

d.The Restricted Person acknowledges that the restrictions contained in this Section 6.7 (i) are reasonable and necessary to protect the legitimate interests of Parent and the goodwill, customer relationships, and Intellectual Property purchased by Parent and (ii) constitute a material inducement to Parent to enter into this Agreement and consummate the Transactions. In the event that

30

any covenant contained in this Section 6.7 should ever be ruled or adjudicated to exceed the time, geographic, product or service, or other limitations permitted by applicable Legal Requirements in any jurisdiction, then any arbitration forum or court is expressly requested and empowered to “blue-pencil” and reform such covenant, and such covenant shall be deemed reformed, in such jurisdiction within the Territory to the maximum time, geographic, product or service, or other limitations permitted by applicable Legal Requirements. The covenants contained in this Section 6.7 and each provision hereof are severable and distinct covenants and provisions. The invalidity or unenforceability of any such covenant or provision (or portion thereof) as written shall not invalidate or render unenforceable the remaining covenants or provisions hereof (or the remaining portions of the subject covenant or provision), and any such invalidity or unenforceability in any jurisdiction shall not invalidate or render unenforceable such covenant or provision in any other jurisdiction.

Section 6.8 Members’ Representative.

By executing this Agreement, the Members’ Representative accepts such appointment, authority and power. Without limiting the generality of the foregoing, the Members’ Representative shall have the power to take any of the following actions on behalf of the Members: to give and receive notices, communications and consents under this Agreement and the CVR Agreement on behalf of the Members and holders of CVRs; to negotiate, enter into settlements and compromises of, resolve and comply with orders of courts and arbitration forums with respect to any disputes arising under this Agreement or the CVR Agreement; and to make, execute, acknowledge and deliver all such other agreements, guarantees, orders, receipts, endorsements, notices, requests, instructions, certificates, stock powers, letters and other writings, and, in general, to do any and all things and to take any and all action that the Members’ Representative, in Members’ Representative’s sole and absolute discretion, may consider necessary or proper or convenient in connection with or to carry out the activities described in this Section 6.8.

b.The appointment of the Members’ Representative by each Member and holder of CVRs by the Members’ collective adoption of this Agreement is coupled with an interest and may not be revoked in whole or in part (including upon the death or incapacity of any member). Such appointment shall be binding upon the heirs, executors, administrators, estates, personal representatives, officers, directors, security holders, successors and assigns of each Member. All decisions of the Members’ Representative shall be final and binding on all of the Members and holders of CVRs, and no Member or holder of CVRs, shall have the right to object, dissent, protest or otherwise contest the same. Parent shall be entitled to rely upon, without independent investigation, any act, notice, instruction or communication from the Members’ Representative and any document executed by the Members’ Representative on behalf of any Member or holder of CVRs and shall be fully protected in connection with any action or

31

inaction taken or omitted to be taken in reliance thereon by Parent absent willful misconduct by Parent. The Members’ Representative shall not be responsible for any Loss suffered by the Members or holders of CVRs arising out of any act done or omitted by the Members’ Representative in connection with the acceptance or administration of the Members’ Representative’s duties hereunder, unless such act or omission involves gross negligence or willful misconduct.

c.In the event that the Members’ Representative dies, becomes unable to perform the Members’ Representative’s responsibilities hereunder or resigns from such position, the holders of at least 50.1% of the then outstanding CVRs shall be authorized to and shall select another representative reasonably acceptable to Parent to fill such vacancy and such substituted representative shall be deemed to be the Members’ Representative for all purposes of this Agreement and the CVR Agreement. The newly-appointed Members’ Representative shall notify Parent, the Surviving Company and any other appropriate Person in writing of his or her appointment and provide appropriate contact information for purposes of this Agreement and the CVR Agreement. Parent shall be entitled to rely upon, without independent investigation, the identity and validity of such newly-appointed Members’ Representative as set forth in such written notice. If for any reason there is no Members’ Representative at any time, all references herein to the Members’ Representative shall be deemed to refer to all of the Members.

d.The Members’ Representative shall serve without compensation.

ARTICLE 7.

SURVIVAL AND INDEMNIFICATION

Section 7.1 Survival of Representations and Warranties. For purposes of determining each Indemnification Amount and the Total Indemnification Amount (as defined below), (a) all representations and warranties contained in Article 4 or any certificate, instrument or document delivered by the Company in connection with this Agreement (and all claims based upon preclosing covenants and agreements herein) shall survive the Closing, irrespective of any facts known to Parent at or before the Closing or any investigation at any time made by or on behalf of Parent, for a survival period of 48 months from the Effective Time, and (b) all representations and warranties contained in Article 3 or any certificate, instrument or document delivered by the Company or any Member in connection with this Agreement shall survive the Closing, irrespective of any facts known to Parent at or before the Closing or any investigation at any time made by or on behalf of Parent, until the date which is 60 days following the applicable status of limitations and no longer - provided, that if Parent delivers to the Members’ Representative, before expiration of such survival period, either a notice asserting a Loss that would constitute an Indemnification Amount, or a notice that, as a result of a Legal Proceeding instituted or claim made by a Person not a party to this Agreement, Parent reasonably expects that Parent or any other Indemnified Party may incur Losses which would constitute an Indemnification Amount, then the applicable representation, warranty, covenant or agreement will survive until, but only for purposes of, the resolution of the matter covered by such notice and the final determination of the actual Loss and the related Indemnification Amount, if any. This Section 7.1 and the determination of each of the Indemnification Amount and of the Total Indemnification Amount will not be affected by any investigation conducted with respect to, or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, by or on behalf of Parent.

Section 7.2 Parent Representations. All representations and warranties made by Parent and Merger Sub shall terminate and expire at the Effective Time, and any liability of Parent or Merger Sub with respect to such representations and warranties shall thereupon cease.

32

Section 7.3 Survival of Covenants. All covenants and agreements of the parties hereto contained herein shall survive the Effective Time until fully waived in writing, performed or complied with.

Section 7.4 Indemnification by the Members and Indemnification Amount. From and after the Effective Time (but subject to Section 7.1 and Section 7.5), the Members shall hold harmless and indemnify each of Parent, any of Parent’s Affiliates, the Surviving Company or any of their respective directors, managers, officers, employees, agents, consultants, advisors, representatives and equityholders (individually the “Indemnified Party” and collectively, the “Indemnified Parties”) from and against, and shall (subject to any limitations expressly set forth herein) compensate and reimburse each Indemnified Party for 100% of the monetary value of any and all Losses directly or indirectly arising out of, relating to or resulting from any of the following, and incurred or suffered by any Indemnified Party (the monetary value of each such Loss being an “Indemnification Amount” and the aggregate monetary value of all Indemnification Amounts being, on a cumulative basis, the “Total Indemnification Amount”):

a.any inaccuracy in or breach of any representation or warranty of the Company and the Members contained in Article 4 of this Agreement or in any certificate, instrument or document delivered by the Company in connection with this Agreement;

b.any breach or inaccuracy of any representation or warranty made by the Members in Article 3 of this Agreement; provided, however, that that the indemnification obligations for any such breach or inaccuracy by a Member shall be limited to the applicable Member;

c.the nonfulfillment, nonperformance or other breach of any covenant or agreement of the Company contained in this Agreement or in any certificate, instrument or document delivered pursuant hereto;

d.the nonfulfillment, nonperformance or other breach of any covenant or agreement of any Member contained in this Agreement or in any certificate, instrument or document delivered pursuant hereto; provided, however, that the indemnification obligations for such a breach or nonperformance by any Member shall be limited to the applicable breaching or nonperforming Member;

e.any Transaction Expenses which are not paid in full at or before the Closing or otherwise reflected as a deduction in the determination of the Merger Consideration;

f.any Indebtedness of the Company which is not paid in full at or before the Closing;

g.any Tax arising during, or payable with respect to, any period ending on or before the Closing (or any portion of any such period) or payable with respect to anything which occurred before the Closing, whether or not known as of the Closing to be owing; and

h.any claim by any actual or purported holder of a CVR, member or former member of the Company, or any other Person, against any of the Indemnified Parties or against any actual or purported holder of a CVR, member or former member of the Company, relating to the Transactions or seeking to assert, or based upon, (i) ownership or rights to ownership of any equity securities of the Company, (ii) any rights of a member of the Company (other than the right of any actual holder of a CVR to receive such member’s portion of the Total Merger Consideration pursuant to the express provisions of this Agreement), including any option, preemptive rights or rights to notice or to vote, (iii) any rights as a member of the Company under the DLLC Act or the Company Charter Documents, in effect as of immediately before the Effective Time, (iv) any fiduciary or statutory duties of the Company or any of its

33

managers, directors, officers or controlling persons, or (v) any claim that his, her or its equity securities of the Company were wrongfully repurchased by the Company.

Section 7.5 Limitations.

a.For purposes of Section 7.4, with respect to each representation, warranty, covenant or agreement contained in this Agreement that is subject to a “materiality,” “material,” “Material Adverse Effect,” “in all material respects” or similar qualification (but not including knowledge or Knowledge of the Company), any such qualification shall be disregarded for purposes of calculating the amount of any Losses that is subject to indemnification hereunder (but not for purposes of determining whether a breach of or inaccuracy in such representation, warranty, covenant or agreement has occurred).

b.Except in the case of fraud by such Member, the liability of each Member pursuant to Section 7.4 shall be capped at 100% of the applicable Member’s Holdback Amount Unpaid plus 50% of the Merger Consideration which would be payable to such Member pursuant to such Member’s CVRs plus (in the case of Vaughn Smider and his Affiliates only) 40% of any cash actually paid to Vaughn Smider and his Affiliates at the Closing and 40% of any Holdback Distribution Amount actually paid to Vaughn Smider and his Affiliates; provided, however, that these limits shall not apply (and, instead, the foregoing caps shall all be 100% instead of 40% or 50%) with respect to the following: (i) Section 7.4(b) (regarding any breach or inaccuracy of any representation or warranty made by the applicable Member in Article 3 of this Agreement); (ii) Section 7.4(d) (regarding the nonfulfillment, nonperformance or other breach of any covenant or agreement of the applicable Member contained in this Agreement or in any certificate, instrument or document delivered pursuant hereto); (iii) Section 7.4(g) (regarding any Tax arising during, or payable with respect to, any period ending on or before the Closing (or any portion of any such period) or payable with respect to anything which occurred before the Closing); and (iv) clause (i) of Section 7.4(h) (regarding any claim by any actual or purported holder of a CVR, member or former member of the Company, or any other Person, in each instance other than a Member, against any of the Indemnified Parties or against any actual or purported holder of a CVR, member or former member of the Company, seeking to assert, or based upon, ownership or rights to ownership of any equity securities of the Company).

c.The obligations of each respective Member under Section 7.4 shall be limited by the principle of several-but-not-joint liability.

d.Except in the case of fraud by such Member, the obligations of each respective Member (other than Vaughn Smider and his Affiliates) under Section 7.4 (as limited under Section 7.5(a)-(c)) may be enforced only by debiting (dollar-for-dollar, upon demand and as incurred) against the Member’s Holdback Amount Unpaid and by debiting (dollar-for-dollar, upon demand and as incurred) amounts that would otherwise have been payable to the Member under the Member’s CVRs (i.e., that would otherwise have been payable to the Member in such Member’s capacity as a “Holder” under the CVR Agreement). For avoidance of doubt: except in the case of fraud by such Member, the obligations of each respective Member (other than Vaughn Smider and his Affiliates) under Section 7.4 (as limited under Section 7.5(a)-(c)) may not be enforced against any cash actually paid to such Member at the Closing, against any Holdback Distribution payments made to such Member or against any cash actually paid to such Member in such Member’s capacity as a “Holder” under the CVR Agreement.

e.The obligations of Vaughn Smider and his Affiliates under Section 7.4 (as limited under Section 7.5(a)-(c)) may be enforced not only by debiting (dollar-for-dollar, upon demand

34

and as incurred) against the Holdback Amount Unpaid of Vaughn Smider and his Affiliates and by debiting (dollar-for-dollar, upon demand and as incurred) amounts that would otherwise have been payable to Vaughn Smider and his Affiliates under the CVRs of Vaughn Smider and his Affiliates (i.e., that would otherwise have been payable to Vaughn Smider and his Affiliates in the capacity as a “Holder” under the CVR Agreement), but also and in addition by a direct claim under Section 8.5 to recover such liability (dollar-for-dollar, upon demand and as incurred) in the form of cash (provided that, except in the case of fraud by Vaughn Smider, the amount of the recovery in the form of cash shall not exceed the sum of 40% of any cash actually paid to Vaughn Smider and his Affiliates at the Closing and 40% of any Holdback Distribution Amount actually paid to Vaughn Smider and his Affiliates). The Indemnified Party(ies) shall not be subject to any election of remedies or to any required sequencing of remedies. Notwithstanding the foregoing, no such direct claim under Section 8.5 to recover such liability shall be commenced after the date which is 24 months after the Effective Time, except in the case of fraud by Vaughn Smider.

Section 7.6 Nonpayment After and Pending Determinations. Parent shall have the right to, subject to any limitations expressly set forth herein, subtract and withhold from any sum that is or may be owed to any Member for the Holdback Distribution or in such Member’s capacity as a “Holder” under the CVR Agreement : (a) each Claimed Amount for which indemnifiability and the size of the Loss have been finally determined (and which has thereby become an established Indemnification Amount); and (b) pending final determination, each Claimed Amount for which final determination has not yet occurred.

Section 7.7 No Contribution. Without limiting the provisions of Section 6.3, no Member has and shall have, as a member or former member of the Company, (and by execution of this Agreement and acceptance of CVRs each Holder, as a member/former member of the Company, waives) any right of subrogation, indemnification or contribution against the Company or any of its pre-Merger managers or other officials with respect to any breach by the Company or any of its pre-Merger managers or other officials or any other Member of any of their respective representations, warranties, covenants or agreements in this Agreement or any duty owed by any of them to such Member (as a Holder or in a prior capacity as a member of the Company) or to the Members generally (as Holders or in their prior capacity as members of the Company), whether by virtue of any equitable, fiduciary, contractual or statutory right of indemnity or otherwise, and all claims to the contrary are hereby waived and released.

Section 7.8 Claim Procedure.

a.If an Indemnified Party determines to seek indemnification under this Article7, it shall give notice in writing to the Members’ Representative (each such notice, a “Claim Notice”), which notice shall set forth such material information with respect to such claim for indemnification as is then reasonably available to the Indemnified Party and shall contain a good faith, non-binding, preliminary estimate of the aggregate amount of the actual and potential Losses that the Indemnified Party believes have arisen and may arise as a result of such facts and circumstances (the aggregate amount of such estimate, as it may be modified by such Indemnitee in good faith from time to time, being referred to as the “Claimed Amount”). In the event that a Claim Notice is given with respect to an Indemnifiable Claim by Third Party, such notice shall be delivered to the Members’ Representative within 20 calendar days of the Indemnified Party becoming aware of such claim.

b.If the Members’ Representative disputes liability with respect to any Claimed Amount or disputes the size of the claimed Loss, the Members’ Representative shall, within 20 calendar days after receiving the Claim Notice (the “Dispute Period”), give written notice of such dispute to the Indemnified Party in which event the parties will negotiate in good faith to mutually agree to resolve such

35

dispute. If the parties are unable to resolve the indemnifiability of such Claimed Amount and the size of the Loss within 30 calendar days after the Members’ Representative delivers such notice, then (i) such dispute shall be settled in accordance with Section 8.5 hereof upon invocation of such procedure by the Indemnified Party or the Members’ Representative, and (ii) if such dispute relates to an Indemnifiable Claim by Third Party, then pending resolution of any such dispute, the Indemnified Party shall have the right to defend, compromise, or settle such Indemnifiable Claim By Third Party (although any compromise or settlement shall require the consent of the Members’ Representative, not to be unreasonably withheld, conditioned or delayed) – but all, if it is ultimately determined that the Indemnifiable Claim By Third Party was indemnifiable, with the same indemnification effect as if there had never been such an indemnifiability dispute. If no written notice of dispute is delivered by the Members’ Representative before the expiration of the Dispute Period, then the Members shall be conclusively deemed to have agreed that the full Claimed Amount is owed to the Indemnified Party (albeit subject in all instances to any limitations expressly set forth herein).

Section 7.9 Indemnifiable Claims By Third Party. A Claim Notice with respect to an Indemnifiable Claim By Third Party shall set forth such material information with respect to such Indemnifiable Claim By Third Party as is then reasonably available to the Indemnified Party. If any such liability is asserted against the Indemnified Party and the Indemnified Party notifies the Members’ Representative of such liability, the Members’ Representative shall be entitled, if the Members’ Representative so elects by written notice delivered to the Indemnified Party within 20 calendar days after receiving the Claim Notice, to assume the defense of such asserted liability with counsel reasonably satisfactory to the Indemnified Party (provided, that the Members’ Representative shall have no such entitlement if Parent reasonably determines, and notifies the Members’ Representative of such determination, that the Members’ Representative lacks the financial wherewithal to properly conduct such defense). If the Members’ Representative elects to assume the defense of such asserted liability, the claims made by such third party shall be conclusively established as being within the scope of and subject to the indemnification provisions of this Agreement. Notwithstanding the foregoing, the Indemnified Party shall have the right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be payable by the Indemnified Party, and the right to (in the scenario where the Members’ Representative shall fail to assume in a timely manner the defense of and reasonably defend such Indemnifiable Claim By Third Party or in the scenario where Parent reasonably determines, and notifies the Members’ Representative of such determination, that the Members’ Representative lacks the financial wherewithal to properly conduct such defense) control the defense and settlement. If the Members’ Representative shall be entitled to and does control the defense of any such Indemnifiable Claim By Third Party, the Members’ Representative shall have the right to settle such Indemnifiable Claim By Third Party; provided, that the Members’ Representative agrees to obtain the prior written consent (which shall not be unreasonably withheld, conditioned or delayed) of the Indemnified Party before entering into any settlement of (or resolving by consent to the entry of judgment upon) such Indemnifiable Claim By Third Party unless (A) there is no finding or admission of any violation of Applicable Law or any violation of the rights of any Person by an Indemnified Party, no requirement that the Indemnified Party admit fault or culpability, and no adverse effect on any other claims that may be made by or against the Indemnified Party and (B) the sole relief provided is monetary damages that are paid in full by the Members’ Representative and such settlement does not require the Indemnified Party to take (or refrain from taking) any action. With respect to any assertion of liability by a third party that results in an Indemnifiable Claim By Third Party, the parties shall make reasonably available to each other all relevant information in their possession that is material to any such assertion and otherwise cooperate in the defense of the Indemnifiable Claim By Third Party subject to their respective attorney-client privileges and work product doctrine protections.

Section 7.10 Exercise of Remedies Other Than by Parent. No Indemnified Party (other than Parent, the Surviving Company or any successor thereto or assign thereof) shall be permitted to assert any

36

indemnification claim or exercise any other remedy under this Agreement unless Parent, the Surviving Company or any successor thereto or assign thereof, as the case may be, shall have consented to the assertion of such indemnification claim or the exercise of such other remedy. The parties acknowledge and agree that, if the Surviving Company suffers, incurs or otherwise becomes subject to any Losses as a result of or in connection with any inaccuracy in or breach of any representation, warranty, covenant or obligation, then (without limiting any of the rights of the Surviving Company as an Indemnified Party) Parent shall also be deemed, by virtue of its ownership of the Ownership Interests of the Surviving Company, to have incurred Losses as a result of and in connection with such inaccuracy or breach; provided, that this Section 7.10 shall not, however, allow a duplicative recovery of the same Losses by Parent, on the one hand, and the Indemnified Parties other than Parent, on the other hand).

Section 7.11 Expenses of the Members’ Representative. The Members’ Representative shall be entitled to recover, on a dollar-for-dollar basis from the next payment(s) otherwise due (after application of all other provisions of the CVR Agreement) to the Holders (as defined in the CVR Agreement), any amounts expended by the Members’ Representative for indemnification/defense or other out-of-pocket costs and expenses pursuant to this Article 7.

Section 7.12 Characterization of Payments.  Any indemnity payments made pursuant to this Article 7 shall constitute an adjustment to the Total Merger Consideration for Tax purposes and shall be treated as such by the parties to this Agreement and the Members on their Tax Returns unless otherwise required by applicable law.

Section 7.13 Exclusive Remedy. Subject to Section 8.11, and except with respect to fraud, Parent and Merger Sub acknowledge and agree that the remedies provided for in this Article 7 shall be the sole and exclusive remedies of Parent, Merger Sub and any other Indemnified Parties with respect to any and all claims against or in respect of any Member relating to this Agreement or the Transactions (including, without limitation, the matters set forth in Section 7.4 as well as any breach, inaccuracy, misrepresentation or nonperformance of any representation, warranty, covenant, agreement or obligation).

Section 7.14 CVRs Catch-Up After Determination. Similarly to Section 2.10, if as of any CVR Payment Date (as defined in the CVR Agreement) there is any Claimed Amount for which final determination has not yet occurred (and for which the CVR Payment Amount (as defined in the CVR Agreement) is therefore reduced), then upon any final determination of non-indemnifiability or of a smaller size of Loss, within 30 days thereafter Parent shall pay each Holder the indicated Claimed Amount (or applicable portion thereof) that had been held back beyond such CVR Payment Date, plus interest as set forth in Section 2.4(a) of the CVR Agreement

ARTICLE 8.

MISCELLANEOUS PROVISIONS

Section 8.1 Amendment. This Agreement may be amended, modified or supplemented in any and all respects by (but only by) written agreement of the parties hereto; provided, that a majority in interest of the Members together with a majority per capita of the Members, both together, shall be and hereby are empowered and authorized to amend, modify, supplement or waive this Agreement or any provision thereof on behalf of all Members, so long as any such amendment, modification, supplement or waiver affects all Members equally or proportionately with respect to their Company Interests, and any such amendment, modification, supplement or waiver shall be binding on all Members, even Members who did not themselves agree to so amend, modify, supplement or waive (or who even opposed doing so).

37

Section 8.2 Waiver.

a.No failure on the part of any party to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any party in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy.

b.Subject to the proviso sentence of Section 8.1, no party shall be deemed to have waived any claim arising out of this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such party; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

Section 8.3 Entire Agreement; Counterparts. This Agreement, the CVR Agreement, any other agreements expressly referred to herein, and the Confidentiality Agreement constitute the entire agreement of the parties hereto and supersede all prior or contemporaneous agreements, commitments and understandings, both written and oral, among or between any of the parties hereto with respect to the subject matter hereof and thereof. This Agreement may be executed in counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument. Parent has made no promises, representations, warranties, covenants, or undertakings, other than those expressly set forth herein and in the CVR Agreement, to induce the Company or the Members to execute and deliver this Agreement, and the Company and each Member, respectively, acknowledges that the Company and such Member has not executed or delivered this Agreement in reliance upon any such promise, representation, or warranty, covenant or undertaking not contained herein. The Company has made no promises, representations, warranties, covenants, or undertakings, other than those expressly set forth herein and in the CVR Agreement, to induce Parent and Merger Sub to execute and deliver this Agreement, and Parent and Merger Sub acknowledge that Parent and Merger Sub have not executed or delivered this Agreement in reliance upon any such promise, representation, or warranty, covenant or undertaking of the Company not contained herein.

Section 8.4 Governing Law. This Agreement, and all claims or causes of action (whether in contract, tort or statute) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement), shall be governed by, construed in accordance with and enforced in accordance with the internal laws of the State of Delaware (including its statutes of limitations and of repose, and without giving effect to any conflicts of law principles that require the application of the law of a different state or country).

Section 8.5 Arbitration.

a.Any and all any disputes, controversies or claims between or among the parties (whether based on contract, tort or otherwise) arising out of or relating to this Agreement shall be exclusively and finally resolved by binding arbitration (using the English language) in accordance with the commercial arbitration rules and administration rules of JAMS then in effect, in San Diego, California, USA. The arbitration shall be conducted by an arbitrator reasonably knowledgeable about acquisition transactions in the pharmaceutical/biotechnology industry and reasonably acceptable to Parent and the Members’ Representative. If Parent and the Members’ Representative cannot agree on a single arbitrator within 30 days after a demand for arbitration has been made, Parent shall appoint an arbitrator, the Members’ Representative shall appoint an arbitrator, the two arbitrators shall appoint a third

38

arbitrator, and the three arbitrators shall hear and decide the issue in controversy. If a party fails to appoint an arbitrator within 45 days after service of the demand for arbitration, then the arbitrator appointed by the other party shall arbitrate any controversy in accordance with this Section 8.5(a). Except as to the selection of arbitrators, the arbitration proceedings shall be conducted promptly and in accordance with the commercial arbitration rules of JAMS then in effect. The expenses of any arbitration, including the reasonable attorney fees and expenses of the prevailing party, shall be awarded by the arbitrator(s) to the prevailing party against the other party.

b.All arbitration proceedings hereunder shall be confidential, and the arbitrator(s) shall issue appropriate protective orders to safeguard each party’s confidential information. Except as required by applicable Legal Requirements, neither Parent nor the Members’ Representative shall make (or instruct the arbitrator(s) to make) any public announcement with respect to the proceedings or decision of the arbitrator(s) without prior written consent of the other.

c.Each party recognizes that the covenants and agreements herein and their continued performance as set forth in this Agreement are necessary and critical to protect the legitimate interests of the other parties, that each other party would not have entered into this Agreement in the absence of such covenants and agreements and the assurance of continued performance as set forth in this Agreement, and that a party’s breach or threatened breach of such covenants and agreements (including, without limitation, Section 6.2, Section 6.5 and Section 6.7) may cause another party irreparable harm and significant injury, the amount of which will be extremely difficult to estimate and ascertain, thus potentially making any remedy at law or in damages inadequate. Therefore, each party confirms and agrees that, notwithstanding Section 8.5(a), any other party shall be entitled to seek (from the arbitrator(s) and/or from any court of competent jurisdiction) on an interim or permanent basis an order for specific performance, an order restraining any breach or threatened breach (of Section 6.2, Section 6.5, Section 6.7 and/or of any or all other provisions of this Agreement), and any other equitable relief (including but not limited to temporary, preliminary and/or permanent injunctive relief), all without need to post any bond or other security, and in addition to and not exclusive of any other remedy available to such other party at law or in equity.

d.No party shall commence any court proceeding or action against the other to resolve any dispute, except to enforce an arbitral award rendered pursuant to this Section 8.5 or for equitable relief. For all purposes of this Agreement (but subject to the preceding sentence), the parties hereby irrevocably consent to personal jurisdiction and venue in the state and federal courts located in San Diego County, California, USA, and irrevocably agree to service of process issued or authorized by any such court in any such action or proceeding. The parties hereby irrevocably waive any objection which they may now have or hereafter have to the laying of venue in the federal or state courts located in San Diego County, California, USA in any such action or proceeding, and hereby irrevocably waive and agree not to plead or claim in any such court that any such action or proceeding brought in any such court has been brought in an inconvenient forum. Notwithstanding anything in this Section 8.5, a party may seek to enforce an arbitral award or pursue equitable relief at any time in any court of competent jurisdiction.

e.The provisions of this Section 8.5 shall survive any termination of this Agreement, and shall be severable and binding on the parties hereto, notwithstanding that any other provision of this Agreement may be held or declared to be invalid, illegal or unenforceable.

Section 8.6 Payment of Expenses. Whether or not the Merger is consummated, each party hereto shall (subject to express provisions hereof resulting in reduction of the Total Merger Consideration) pay its own expenses incident to this Agreement and preparing for, and otherwise in connection with, the Transactions.

39

Section 8.7 Transfer Taxes. All transfer, documentary, sales, use, stamp, registration and other substantially similar Taxes and fees (including any penalties and interest) incurred in connection with this Agreement (collectively, “Transfer Taxes”) shall be paid by Parent and Merger Sub when due, and Parent and Merger Sub will, at their own expense, file all necessary Tax Returns and other documentation with respect to all such Transfer Taxes.

Section 8.8 Assignability; No Third Party Rights. Before the Effective Time, neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, in whole or in part, by operation of a Legal Requirement or otherwise, by any of the parties without the prior written consent of the other parties and any purported assignment without such consent shall be void. This Agreement shall be binding upon, and shall be enforceable by and inure to the benefit of, the parties hereto and their respective permitted successors and assigns. Except (a) any rights of holders of Company Interests to receive payment in accordance with Article 2 after the Effective Time, and (b) as set forth in Section 6.3 (Indemnification of D&O Indemnified Parties), nothing in this Agreement, express or implied, is intended to or shall confer upon any Person, other than the parties hereto, any right, benefit or remedy of any nature. To the extent permitted by applicable Legal Requirements, it is expressly agreed that in no event shall any former members of the Company (as opposed to the Members’ Representative in the name of and on behalf of such former member(s) of the Company) or any holders of CVRs (as opposed to the Members’ Representative in the name of and on behalf of such holder(s) of CVRs) have, after the Effective Time, any power or right to commence or join in any Legal Proceeding based on or arising out of the Transactions, this Agreement, the CVR Agreement or the CVRs.

Section 8.9 Notices. Any notice, request, approval, consent or other such communication required or permitted to be given under this Agreement or the CVR Agreement shall be in writing and shall be deemed to have been sufficiently given if and only if delivered in person, by email or by internationally recognized overnight courier service to the party to which it is directed at its physical or email address shown below or such other physical or email address as such Party shall have last given by such written notice to the other party in accordance with this Section:

Section 8.10 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court (or arbitration forum) of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court (or arbitration forum) making such determination shall have the power to limit the term or provision, to delete specific words or phrases or to replace any invalid or unenforceable term or provision with a term or provision that is valid and

41

enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. In the event such court (or arbitration forum) does not exercise the power granted to it in the prior sentence, the parties hereto agree to negotiate in good faith to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.

Section 8.11 Specific Performance. The parties hereto agree that irreparable damage would occur in the event any of the provisions of this Agreement were not to be performed in accordance with the terms hereof and that the parties shall be entitled to specific performance of the terms hereof and/or to temporary, preliminary and/or permanent injunctive relief, in addition to any other remedies at law or in equity. Each party agrees to waive any requirement for the posting of, or securing of, a bond in connection with any such remedy.

Section 8.12 Remedies. All rights and remedies of either party hereto are cumulative of each other and of every other right or remedy such party may otherwise have at law or in equity, and the exercise of one or more rights or remedies shall not prejudice or impair the concurrent or subsequent exercise of other rights or remedies.

Section 8.13 Construction.

a.For purposes of this Agreement, whenever the context requires: the singular number shall include the plural, and vice versa; the masculine gender shall include the feminine and neuter genders; the feminine gender shall include the masculine and neuter genders; and the neuter gender shall include the masculine and feminine genders.

b.The parties hereto agree that any rule of construction to the effect that ambiguities are to be resolved against the drafting party shall not be applied in the construction or interpretation of this Agreement.

c.As used in this Agreement, the words “include” and “including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation.”

d.Except as otherwise indicated, all references in this Agreement to “Articles,” “Sections” and “Exhibits” are intended to refer to Articles, Sections or Exhibits to this Agreement, as the case may be.

e.All references in this Agreement to “$” are intended to refer to U.S. dollars.

f.Unless otherwise specifically provided for herein, the term “or” shall not be deemed to be exclusive.
