1.3 Non Assignable Contracts.

(a) Notwithstanding anything to the contrary in this Agreement, this Agreement shall not constitute an agreement to transfer or assign any Assumed Contract or any claim, right or benefit arising under or resulting from any such Assumed Contract if a transfer or an assignment, or attempted transfer or assignment, of the same without the consent of a third party would constitute a material breach or other contravention of the rights of such third party, would be ineffective with respect to an agreement concerning such Assumed Contract or would in any way impair the rights of Poseida or Transposagen with respect thereto. If any assignment of any such Assumed Contract by Transposagen to Poseida, or any assumption by Poseida of any interest, liability, obligation or commitment under, any such Assumed Contract requires any such consent or approval, then such assignment or assumption shall be made subject to such consent or approval being obtained and, after receipt of such consent or approval, such assignment and assumption shall be deemed to have been effected in accordance with the terms of this Agreement.

(b) Transposagen or Poseida, as the case may be, shall use its commercially reasonable efforts (it being understood that such efforts shall not include any requirement of Poseida or Transposagen to expend money or offer or grant any financial accommodation), to

2

obtain all consents, approvals and waivers and to resolve all impracticalities of assignments or transfers necessary to convey to Poseida the Assumed Contracts so to be conveyed pursuant to Section 1.1.

(c) If any consent, approval or waiver necessary to assign or transfer to Poseida any Assumed Contract as contemplated by clause (b) is not obtained, then, pending the attainment of such consent, approval or waiver pursuant to clause (b), Transposagen and Poseida will cooperate in a mutually agreeable arrangement under which Poseida would obtain the benefits and assume the obligations with respect thereto as contemplated by this Agreement and as reasonably permitted under the terms of such Assumed Contract, at no cost to Poseida (other than the reimbursement of all reasonable costs and expenses directly incurred by Transposagen or any of its Subsidiaries in performing under the terms of such Assumed Contract under this clause (c), including costs and expenses associated with payments made to third parties in respect of any Assumed Contract that is the subject of this clause (c)).

1.4 Shared Assets. Each Party shall use commercially reasonable efforts to determine the extent, if any, to which an asset, property or right described in Section 1.1 or Section 1.2, as applicable, is necessary to retain, control or use both a Contributed Asset and a Retained Asset, including those items so designated on the schedules in Sections 1.1 and 1.2 (a “Shared Asset”). For each such Shared Asset for which the Parties have not already agreed how to apportion, divide or use pursuant to the License Agreements, the Services Agreement or the Trademark License Agreements, the Parties shall cooperate in good faith to provide, as appropriate, for (i) the allocation and division of such Shared Asset between the Parties prior to the Closing to the extent commercially practicable; or (ii) if such Shared Asset is not capable of being so allocated and divided, then the Parties shall provide for the shared use or ownership of any such Shared Asset, from one Party to the other, whether by lease, sublease, license, sublicense or similar agreement under an appropriate agreement providing for use by the other Party on commercially reasonable terms and without cost (other than, if applicable, the reimbursement of all reasonable costs and expenses directly incurred by one Party in making such Shared Asset available to the other Party, including all costs and expenses associated with payments made to third parties in respect of such Shared Asset).

This Agreement has been duly executed and delivered by Transposagen and, assuming the due authorization, execution and delivery of this Agreement by Poseida, constitutes a legal, valid and binding obligation of Transposagen, enforceable against Transposagen in accordance with its terms, subject to bankruptcy, insolvency, moratorium, reorganization or similar laws affecting the rights of creditors generally and the availability of equitable remedies.

(c) No Conflict. The execution, delivery, and performance of and compliance with this Agreement will not, with or without the passage of time or giving of notice, (a) conflict with, or result in any violation of or default or loss of any benefit under, any provision of the certificate of incorporation or bylaws of Transposagen; (b) conflict with, or result in any violation of or default or loss of any benefit under, any permit, concession, grant, franchise, law, rule or regulation, or any order to which Transposagen is a party or to which any of its property is subject; (c) conflict with, or result in a breach or violation of or default or loss of any benefit under, or accelerate the performance required by, the terms of any agreement, contract, indenture or other instrument to which Transposagen is a party or to which any of its property is subject, or constitute a default or loss of any right thereunder or an event that, with the lapse of time or notice or both, might result in a default or loss of any right thereunder or the creation of any Encumbrance upon

Poseida is duly qualified or licensed to do business and is in good standing in each jurisdiction in which the nature of its business or the ownership, leasing or operation of its properties makes such qualification or licensing necessary, other than in such jurisdictions where the failure to be so qualified or licensed individually or in the aggregate has not had and would not reasonably be expected to have a material adverse effect on Poseida.

The Indemnifying Party shall be responsible for the fees and expenses of counsel employed by the Indemnitee; provided, however, that in no event shall the Indemnifying Party be liable for the fees and expenses of more than one counsel (in addition to any local counsel) for all Indemnitees in connection with any one action or separate but similar or related actions arising out of the same general allegations or circumstances; and provided, further, that if the Indemnifying Party elects to assume the defense of the Third Party

11

Claims in accordance with clause (ii) below, the Indemnifying Party shall not be liable to any Indemnitee for any legal expenses subsequently incurred by such Indemnitee in connection with the defense thereof.

(ii) The Indemnifying Party shall be entitled to participate in the defense of a Third Party Claim through its counsel, at its own expense, and, if it so chooses, to assume the defense thereof (at the expense of the Indemnifying Party) with counsel selected by the Indemnifying Party and reasonably satisfactory to the Indemnitee. If the Indemnifying Party assumes such defense, the Indemnitee shall have the right to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnifying Party, it being understood that the Indemnifying Party shall control all proceedings taken in connection with such Third Party Claim and, without limiting the foregoing, may in its sole discretion, subject to the last sentence of this paragraph (ii), pursue or forego any and all administrative appeals, proceedings, hearings and conferences with any Governmental Entity with respect thereto, and, subject to the last sentence of this paragraph (ii), may in its sole discretion, either pay the amount claimed and sue for a refund where applicable law permits such refund suits, settle or contest the Third Party Claim in any permissible manner. Notwithstanding the foregoing, the Indemnifying Party shall not be entitled to assume the defense of any Third Party Claim (and shall be liable for the reasonable fees and expenses of counsel incurred by the Indemnitee in defending such Third Party Claim) if (1) the Third Party Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the Indemnitee which the Indemnitee reasonably determines, after conferring with its counsel, cannot be separated from any related claim for money damages, or (2) the settlement of, or an adverse judgment with respect to, the Third Party Claim is reasonably likely to, in the good faith judgment of the Indemnitee, establish a precedential custom or practice adverse to the continuing business interests of the Indemnitee, (3) the Third Party Claim relates to any Intellectual Property of the Indemnitee or any of its affiliates, or (4) the Third Party Claim is reasonably likely to lead to criminal charges against the Indemnitee or any of its affiliates. If the Indemnifying Party chooses to defend or prosecute a Third Party Claim, the Indemnitee will agree to any settlement, compromise or discharge of such Third Party Claim which the Indemnifying Party may recommend and which by its terms obligates the Indemnifying Party to pay the full amount of the liability in connection with such Third Party Claim; provided, however, that, without the Indemnitee’s consent, the Indemnifying Party shall not consent to entry of any judgment or enter into any settlement (x) that provides for injunctive or other nonmonetary relief affecting the Indemnitee or (y) that does not include as an unconditional term thereof the giving by each claimant or plaintiff to such Indemnitee of a release from all liability with respect to such claim.

(iii) So long as the Indemnitee is participating in the defense of a Third Party Claim in good faith, the Indemnifying Party shall reasonably cooperate with the Indemnitee by providing records and information on a timely basis that are reasonably relevant to such Third Party Claim, and shall in good faith regularly consult with counsel for the Indemnitee and include such counsel in relevant conferences and proceedings to the extent requested by such counsel. If the Indemnifying Party has assumed the defense of a Third Party Claim, the Indemnitee shall not settle, compromise or voluntarily pay any Third Party Claim without the written consent of the Indemnifying Party, which consent will not be unreasonably withheld, delayed or conditioned. No such consent will be required if the Indemnitee agrees in writing to forego all claims for indemnification from the Indemnifying Party with respect to such Third Party Claim, or the

12

Indemnitee reasonably believes itself to be potentially or actually exposed to (A) Losses in excess of amounts reasonably expected to be received from the Indemnifying Party or (B) to non-monetary remedies; provided, however, that the Indemnitee uses reasonable efforts to obtain in such settlement a release of the Indemnifying Party and other Indemnitees with respect to all such Third Party Claims.

(b) In the event any Indemnitee should have a claim against any Indemnifying Party that does not involve a Third Party Claim being asserted against or sought to be collected from such Indemnitee (a “Direct Claim”), the Indemnitee shall deliver notice of such Direct Claim, in writing and in reasonable detail and with reasonable promptness, to the Indemnifying Party. The failure by any Indemnitee to so notify the Indemnifying Party hereunder shall not relieve the Indemnifying Party of its obligations hereunder except to the extent (and only to the extent) that the Indemnifying Party is actually and materially prejudiced by such failure. If the Indemnifying Party does not notify the Indemnitee within 30 calendar days following its receipt of such notice that such Indemnifying Party disputes its liability to the Indemnitee, such Direct Claim specified by the Indemnitee in such notice shall be conclusively deemed a liability subject to indemnification pursuant to this Agreement. If the Indemnifying Party has timely disputed its liability with respect to such Direct Claim as provided above, the Indemnitee and the Indemnifying Party shall attempt to resolve in good faith such dispute within 60 days of the Indemnifying Party providing notice to the Indemnitee of the dispute of liability (it being understood that such good faith attempt shall not require either party to submit the dispute to arbitration). If such dispute is not so resolved within such 60-day period, then either party may initiate a lawsuit with respect to the subject matter of such dispute.

8.4 Successors.

(a) None of Poseida or any of the Poseida Subsidiary Indemnitors shall consolidate with or merge with or into, or sell, convey, transfer or lease, in one transaction or a series of transactions, all or substantially all of its assets to, any person (including through a dividend or distribution of all or substantially all of its assets to a parent entity), unless the resulting, surviving or transferee person (the “Poseida Successor”) shall expressly assume by written instrument all the obligations of such Poseida Indemnitor under this Agreement. The Poseida Successor shall be the successor to Poseida or such Poseida Subsidiary Indemnitor, as applicable, and shall succeed to, and be substituted for, such Poseida or Poseida Subsidiary Indemnitor, as applicable, under this Agreement, but, in the case of any such sale, conveyance, transfer or lease, Poseida or such Poseida Subsidiary Indemnitor, as applicable, shall not be released from its obligations hereunder.

(b) None of Transposagen or any of Transposagen Subsidiary Indemnitors shall consolidate with or merge with or into, or sell, convey, transfer or lease, in one transaction or a series of transactions, all or substantially all of its assets to, any person (including through a dividend or distribution of all or substantially all of its assets to a parent entity), unless the resulting, surviving or transferee person (the “Transposagen Successor”) shall expressly assume all the obligations of such Transposagen Indemnitor under this Agreement. Transposagen Successor shall be the successor to Transposagen or such Transposagen Subsidiary Indemnitor, as applicable, and shall succeed to, and be substituted for, Transposagen or such Transposagen Subsidiary Indemnitor, as applicable, under this Agreement, but, in the case of any such sale,

13

conveyance, transfer or lease, Transposagen or such Transposagen Subsidiary Indemnitor, as applicable, shall not be released from its obligations hereunder.

8.5 Third Party Rights.

(a) In the event that after the Closing Poseida or any of its Subsidiaries holds any right to indemnification or any other contractual or other right (collectively, a “Poseida Recourse Right”) with respect to any Retained Liability or any Assumed Liability for which any Transposagen Indemnitee is held responsible, or for which any Poseida Indemnitee is entitled to indemnification pursuant to Section 8.2, then Poseida or the applicable Subsidiary of Poseida shall use its commercially reasonable efforts (based on Poseida’s or such Subsidiary’s reasonable business judgment exercised in a manner consistent with its ordinary course business practices with respect to similar rights, including elections to forego exercising any such rights) to exercise such rights and, for purposes of the indemnities provided by Transposagen and Transposagen Subsidiary Indemnitors pursuant to Section 8.2, any Losses hereunder shall be net of any amount received by the Poseida Indemnitee in respect of such rights (after giving effect to any expenses or other costs (including all fees and expenses of counsel) incurred by the Indemnitee in exercising such rights). Poseida hereby agrees that the terms of this Section 8.5(a) shall require Poseida and its Subsidiaries to exercise any Poseida Recourse Right to the extent that the failure to exercise such right would result in any Poseida Indemnitor being unable to satisfy all or any portion of its indemnification obligations under Section 8.1(a).

(b) In the event that after the Closing Transposagen or any of its Subsidiaries holds any right to indemnification or any other contractual or other right (collectively, a “Transposagen Recourse Right”) with respect to any Assumed Liability or any Retained Liability for which any Poseida Indemnitee is held responsible, or for which any Transposagen Indemnitee is entitled to indemnification under Section 8.1, then Transposagen shall use its commercially reasonable efforts to exercise such rights and, for purposes of the indemnities provided by Poseida and the Poseida Subsidiary Indemnitors pursuant to Section 8.1, any Losses hereunder shall be net of any amount received by Transposagen Indemnitee in respect of such rights (after giving effect to any expenses or other costs (including all fees and expenses of counsel) incurred by the Indemnitee in exercising such rights). Transposagen hereby agrees that the terms of this Section 8.5(b) shall require Transposagen and its Subsidiaries to exercise any Transposagen Recourse Right to the extent that the failure to exercise such right would result in any Transposagen Indemnitor being unable to satisfy all or any portion of its indemnification obligations under Section 8.2(a).

8.6 Other Payments. For purposes of the indemnities provided in this Agreement, any Losses of any Indemnitee hereunder shall be net of any amount actually recovered by such Indemnitee with respect to such Losses under any insurance policies.
