2.5		Exclusive Option and Exclusive License Acknowledgements
		2.5.1 Licensee acknowledges and agrees that the exclusive options granted under Sections 2.2 and 2.3.2 only apply to Research Targets and Pre-Clinical Targets under this Agreement, and that such exclusive options shall not preclude IIPH from granting, for any use and to any Third Party, exclusive options to any Targets that are not a Research Target, Pre-Clinical Target, or Clinical Target under this Agreement.
		2.5.2 Licensee acknowledges and agrees that the exclusive license granted under Section 2.4 is limited to Clinical Targets under this Agreement, and that such exclusive license shall not preclude IIPH from granting, for any use and to any Third Party, exclusive licenses to any Targets that are not a Research Target, Pre-Clinical Target, or Clinical Target under this Agreement.
2.6		Limited Right to Extend Certain Rights Granted Hereunder to Alliance Partners The grant of rights to Licensee in Sections 2.1, 2.3.1, and 2.4 (in the case of Sections 2.3.1 and 2.4, only upon activation of such rights by exercise of a Pre-Clinical Option or Clinical Option and payment therefor, respectively) includes the right for Licensee to extend to Alliance Partners the following rights:

	(a)		the rights under Section 2.1 to use and import Licensed Products for Research Targets, and
	(b)		the rights under Section 2.3.1 to use and import Licensed Products for Pre-Clinical Targets, and
	(c)		the rights under Section 2.4 to use, import, offer for sale, and sell Licensed Products for Clinical Targets,

provided that in all cases such rights are extended only in conjunction with equivalent or greater rights to Licensee Technology pursuant to a written agreement between such Alliance Partner and Licensee, which written agreement (i) contains restrictions on the use of Licensed Products no less stringent than those contained in this Agreement, (ii) restricts further transfer of any Licensed Products to any Third Party (other than the sale of Licensed Products for Clinical Targets), (iii) grants to IIPH and its Affiliates the right to audit under the terms and conditions in Section 5.2, and (iv) requires that such Alliance Partner agree in writing to transfer to Licensee or destroy any Licensed Products in its possession upon completion or termination of its activities for Licensee under such written agreement.

Licensee agrees that continued extension by Licensee of rights pursuant to this Section 2.6 to an Alliance Partner which Licensee is aware is using such Licensed Product other than as permitted shall constitute a material breach by Licensee under this Agreement. Notwithstanding the foregoing, Licensee shall remain responsible for its own, its Affiliates, and its Alliance Partners’ performance under this Agreement.

2.7		Assurance of Supply Starting from the date of Licensee’s first exercise of a Pre-Clinical Option and continuing for the Term, IIPH agrees to make commercially reasonable licensing terms available to at least one Third Party supplier of Licensed Products for the Pre-Clinical Field. If Licensee is unable to obtain, from Invitrogen or a Third Party licensed by IIPH or Invitrogen, a supply of Licensed Products that meet reasonable specifications for quality, quantity, or timely delivery, Licensee shall notify IIPH in writing (in accordance with Section 12.2) of such fact and shall provide a written explanation of such issue. In the event that IIPH or its Affiliates is unable to provide, either directly or indirectly through a licensed Third Party supplier, a supply of Licensed Products that meet reasonable specifications for quality, quantity, or timely delivery within one hundred twenty (120) days following receipt of such notice, Licensee shall have the right to make (but not have made) Licensed Products for use under the terms of this Agreement until the earlier of such time as (i) IIPH or its Affiliates is able to provide, either directly or indirectly through a licensed Third Party supplier, a supply of Licensed Products that meet reasonable specifications for quality, quantity, or timely delivery, or (ii) this Agreement is terminated.
2.8		No Other Rights No other rights are provided by implication or otherwise beyond those expressly provided in this Agreement.
2.9		Reservation of Rights Except as is specifically provided herein, this Agreement shall not limit the rights of IIPH itself or through its Affiliates to practice under Licensed Patents and to license, assign or otherwise transfer such rights to others for any purpose whatsoever.
3.		Research Target Addition and Removal
3.1		Research Target Addition. No more than once per calendar quarter, Licensee shall have the right to request the addition of one or more Targets to the list of Research Targets set forth in Exhibit A by notifying IIPH in writing of the gene target name and any other information (including the Genbank accession number, if any) useful for identifying the Target to be added. IIPH shall respond in writing within thirty (30) days of receipt of Licensee’s request indicating its decision to grant or withhold consent for each Target identified in such request, such consent only to be withheld if the requested Target (i) is the subject of a license negotiation or evaluation pursuant to a license negotiation between IIPH and a Third Party, which negotiation or evaluation was initiated prior to Licensee’s notification of IIPH or (ii) has been licensed to a Third Party prior to Licensee’s notification of IIPH. For those Targets, if any, for which IIPH grants the foregoing consent, the date of Licensee’s receipt of IIPH’s written consent (“Consent Date”) shall constitute the effective date of addition of such Target(s) as a Research Target(s) under this Agreement. In the event that IIPH refuses consent, it shall notify Licensee in writing that the requested Target is already subject to either (i) a license negotiation or evaluation or (ii) a license agreement with a Third Party as previously set forth in this paragraph. Failure by IIPH to respond or decline to grant any request within thirty (30) days of receipt shall not be interpreted as consent by IIPH to such request. In those cases in which IIPH has already granted to a Third Party a non-exclusive license in the Clinical Field to a Target requested by Licensee, Licensee shall have the right to obtain a non-exclusive license in the Clinical Field to such Target under terms and

CONFIDENTIAL		EXECUTION VERSION

		conditions equivalent to such Third Party non-exclusive license for such Target. For any exclusive licenses or exclusive license options to Targets granted by IIPH to Third Parties under Licensed Patents in the Clinical Field, IIPH agrees hereby to use reasonable efforts, consistent with sound business practice, to grant such licenses or license options (as the case will be) to such Targets under terms which are comparable or greater in value on an aggregate basis to the terms set forth in this Agreement.
3.2		Research Target Removal Any existing Research Target may be removed by Licensee from the list in Exhibit A at any time upon written notice to IIPH in accordance with Section 12.2. The removal of such Research Target shall automatically terminate all licenses and options granted for such Research Target under this Agreement and shall become effective upon receipt by IIPH of such written notice from Licensee. Research Targets removed from this Agreement prior to the anniversary of the Consent Date shall not be subject to the corresponding annual fee set forth in Section 4.2.2.
4.		Financial Terms
4.1		Upfront License Fee and Annual Maintenance Fees
		4.1.1 Upfront License Fee Licensee shall pay to IIPH a non-refundable Upfront License Fee of two hundred fifty thousand U.S. dollars ($250,000.00). The obligation to pay such Upfront License Fee vests on the Effective Date, and Licensee shall make payment within thirty (30) days of the Effective Date.

Annual Maintenance Fees due in any single year shall be creditable only toward those Research Target and Option Fees set forth in Section 4.2 which are due and payable in the twelve (12) months subsequent to such October 30. For clarity, Annual Maintenance Fees shall not be creditable against any milestones or fees due under this Agreement other than the Research Target and Option Grant Fees set forth in Section 4.2.
		Licensee shall have an option to make a payment to IIPH under this Section 4.1.2 of three hundred and seventy-five thousand dollars ($375,000.00) every year (instead of $250,000), which shall entitle Licensee to reduce the fully stacked royalty rate otherwise due to IIPH in Section 5.1.2 to no less than one and a half percent (1.5%) for as long as Licensee’s yearly payments under this Section 4.1.2 continue to be three hundred and seventy-five thousand dollars ($375,000.00). If in any year Licensee fails to pay IIPH three hundred and seventy-five thousand dollars ($375,000.00) under this Section 4.1.2, then the fully stacked royalty rate otherwise due to IIPH in Section 5.1.2 shall remain at or revert to no less than two percent (2%) for the remainder of the Term.
		If Licensee intends to exercise the foregoing option, Licensee shall so advise Licensor in writing no later than forty five (45) days prior to the scheduled payment date. If Licensee elects to reduce the payments under this Section 4.1.2 to two hundred and fifty thousand

CONFIDENTIAL		EXECUTION VERSION

		dollars ($250,000.00) per year, Licensee shall provide notice to Licensor in writing no less than forty five (45) days prior to the next scheduled payment date. If Licensee exercises the foregoing option, and later reduces the payments under this Section 4.1.2 to two hundred and fifty thousand dollars ($250,000.00) per year, Licensee shall thereafter have no right to reduce the fully stacked royalty rate below two percent (2%).

5.2		Records Licensee shall keep, and shall require its Affiliates and Alliance Partners to keep, full, true and accurate books of account containing all particulars which may be necessary for the purpose of showing the amount payable by way of royalty or by way of any other provision under this Agreement. Such books and the supporting data shall be open at all reasonable times during normal business hours and upon reasonable advance notice, for three (3) years following the end of the calendar quarter to which they pertain (and access shall not be denied thereafter, if such records are reasonably available), to the inspection of an independent certified public accountant retained by IIPH and reasonably acceptable to Licensee for the purpose of verifying Licensee’s royalty statements in respect of sales by Licensee, its Affiliates, and/or Alliance Partners, or Licensee’s, its Affiliates, or its Alliance Partners compliance in other respects with this Agreement. Such inspection may take place no more often than once in any calendar year. If in dispute, such records shall be kept until the dispute is settled. IIPH acknowledges that the information provided by Licensee, its Affiliates, and/or Alliance Partners to any such independent certified public accountant for inspection purposes may be confidential, and that Licensee may require such independent certified public accountant to enter into an appropriate confidentiality agreement that protects the confidentiality of Licensee’s, its Affiliates, and/or Alliance Partners’ confidential information. The inspection of records shall be at IIPH’s sole cost unless the inspector concludes that royalties reported by Licensee for the period being audited are understated by five percent (5%) or more from actual royalties, in which case the underpayment will be due immediately and the costs and expenses of such inspection shall be paid by Licensee.
