Section  2.08      Subcontracting . Any and all subcontracts entered into by the RECIPIENT in relation to the performance of activities under the Project shall be in writing and shall be subject to the requirements of this Contract.

For purposes of this section, an assignment or transfer of this Contract by the RECIPIENT in connection with a merger, transfer or sale of all or substantially all of the RECIPIENT’s assets or business related to this Contract or a consolidation, change of control or similar transaction involving the RECIPIENT shall not be deemed to constitute a transfer or assignment, so long as such action does not impair or otherwise negatively impact the revenue sharing terms in Attachment D.

Section  2.11      Reliance upon Representations . By awarding the Grant and executing this Contract, the INSTITUTE is relying, and will continue to rely throughout the term of this Contract, upon the truthfulness, accuracy, and completeness of the RECIPIENT’s written assurances, certifications and representations. Moreover, the INSTITUTE would not have entered into this Contract with the RECIPIENT but for such written assurances, certifications and representations. The RECIPIENT acknowledges that the INSTITUTE is relying upon such assurances, certifications and representations and acknowledges their materiality and significance.

Section  2.12      Contingent upon Availability of Grant Funds . This Contract is contingent upon funding being available for the term of the Contract and the RECIPIENT shall have no right of action against the INSTITUTE in the event that the INSTITUTE is unable to perform its obligations under this Contract as a result of the suspension, termination, withdrawal, or failure of funding to the INSTITUTE or lack of sufficient funding of the INSTITUTE for this Contract. If funds become unavailable to the INSTITUTE during the term of the Contract, Section 8.01(c) shall apply. For the sake of clarity, and except as otherwise provided by this Contract, if this Contract is not funded, then both parties are relieved of all of their obligations under this Contract. The INSTITUTE acknowledges and agrees that the Project is a multiyear project subject to Tex. Health & Safety Code, Ch. 102, Section 102.257.

Section  2.13      Confidentiality of Documents and Information . In connection with work contemplated for the Project or pursuant to complying with various provisions of this Contract, the RECIPIENT may disclose its confidential business, financial, technical, scientific information and other information to the INSTITUTE (“Confidential Information”). To assist the INSTITUTE in identifying such information, the RECIPIENT shall mark or designate the information as “confidential,” provided however that the failure to so designate does not operate as a waiver to protections provided by applicable law or this Contract. The INSTITUTE shall use no less than reasonable care to protect the confidentiality of the Confidential Information to the fullest extent permissible under the Texas Public Information Act, Texas Government Code, Chapter 552 (the “ TPIA ”), and, except as otherwise provided in the TPIA to prevent the disclosure of the Confidential Information to third parties for a period of time equal to three (3) years from the termination of the contract, unless the INSTITUTE and the RECIPIENT agree in writing to extend such time period, provided that this obligation shall not apply to information that:

The INSTITUTE shall hold the Confidential Information in confidence, shall not use such Confidential Information except as provided by the terms of this Contract, and shall not disclose such Confidential Information to third parties without the prior written approval of the RECIPIENT or as otherwise allowed by the terms of the Contract. Subject in all respects to the terms of this Contract and the TPIA, the INSTITUTE has the right to use and disclose the Confidential Information reasonably in connection with the exercise of its rights under the Contract.

In the event that the INSTITUTE is requested or required (by oral questions, interrogatories, requests for information or documents in legal proceedings, subpoena, civil investigative demand or other similar process by a court of competent jurisdiction or by any administrative, legislative, regulatory or self-regulatory authority or entity) to disclose any Confidential Information, the INSTITUTE shall provide the RECIPIENT with prompt written notice of any such request or requirement so that the RECIPIENT may seek a protective order or other appropriate remedy. If, in the absence of a protective order or other remedy, the INSTITUTE is nonetheless legally compelled to make any such disclosure of Confidential Information to any person, the INSTITUTE may, without liability hereunder, disclose only that portion of the Confidential Information that is legally required to be disclosed, provided that the INSTITUTE will use reasonable efforts to assist the RECIPIENT, at the RECIPIENT’s expense, in obtaining an appropriate protective order or other reliable assurance that confidential treatment will be accorded the Confidential Information. To the extent that such Confidential Information does not become part of the public domain by virtue of such disclosure, it shall remain Confidential Information hereunder.

Article III

DISBURSEMENT OF GRANT AWARD PROCEEDS

Section  3.01      Payment of Grant Award Proceeds . The INSTITUTE will advance Grant award proceeds upon request by the RECIPIENT, consistent with the amounts and schedule as provided in Attachment B. If the RECIPIENT does not request or the Oversight Committee does not authorize advancement of funds for some or the entire Grant award proceeds, disbursement of Grant award proceeds for services performed and allowable expenses and costs incurred pursuant to the Scope of Work will be on a reimbursement basis. To the extent that completion of certain milestones is associated with a specific tranche of funding as reflected in the Scope of Work, those milestones shall be accomplished before funding may be provided for next tranche of funding. The INSTITUTE reserves the right to terminate the Contract should a key milestone not be met.

Section  3.02      Requests for Reimbursement and Quarterly Financial Status Reports . If the RECIPIENT does not receive an advance disbursement of Grant proceeds, the RECIPIENT’s requests for reimbursement shall be made on INSTITUTE Form 269a (Financial Status Report). If the RECIPIENT has elected to receive an advance disbursement of Grant proceeds, RECIPIENT shall submit INSTITUTE Form 269a (Financial Status Report) to document all costs and allowable expenses paid with Grant proceeds. The RECIPIENT shall submit the INSTITUTE Form 269a quarterly to the INSTITUTE within 90 days following the end of the quarter covered by the bill. A final INSTITUTE Form 269a shall be submitted by RECIPIENT not later than 90 days after the Termination Date. An extension of time for submission deadlines specified herein must be expressly authorized in writing by the INSTITUTE.

Section  3.03      Actual Costs and Allowable Expenses . Because the Approved budget for the Project(s) as set forth in Attachment B is only an estimate, the parties agree that the RECIPIENT’s billings under this Contract will reflect the actual costs and expenses incurred in performing the Project(s), regardless of the Approved Budget, up to the total contracted amount specified in Section 2.01 “Award of Monies.” The RECIPIENT shall use Grant proceeds only for allowable expenses consistent with state law and agency administrative rules. Allowable expenses for the Project(s) shall be only as outlined in the Approved Budget and any modifications to same.

Section  3.04      Travel Expenses . Reimbursement for travel expenditures shall be in accordance with the Approved Budget. Prior written approval from the INSTITUTE must be obtained before travel that exceeds the amount included in the Approved Budget commences. Failure to obtain such prior written approval shall result in such excess travel costs constituting expenses that may not be taken into account for the purposes of calculating expenditure of Grant funds under this Contract.

Section  3.05      Budget Modifications . The total Approved Budget and the assignment of costs may be adjusted based on implementation of the Scope of Work, spending patterns, and unexpended funds, but only by an amendment to the Approved Budget. In no event shall an amendment to the Approved Budget result in payments in excess of the aggregate amount specified in Section 2.01 “Award of Monies” or in approved supplemental funding for the Project, if any. The RECIPIENT may make transfers between or among lines within budget categories without prior written approval provided that:

All other budget changes or transfers require the INSTITUTE’s express prior written approval. Transfer of funds between categories in the Project’s Approved Budget may be allowed if requests are in writing, fit within the Scope of Work and the total Approved Budget, are beneficial to the achievement of the objectives of the Project, and appear to be an efficient, effective use of the INSTITUTE’s funds.

Section  3.06      Withholding Payment. The INSTITUTE may withhold Grant award proceeds from RECIPIENT if required Financial Status Reports (Form 269a) are not on file for previous quarters or for the final period, if material program requirements are not met and remain uncured after a reasonable time period to cure, if the RECIPIENT is in breach of any material term of this Contract, or in accordance with provisions of this Contract as well as applicable state or federal laws, regulations or administrative rules, and the breach remains uncured after a reasonable time period to cure. The INSTITUTE shall have the right to withhold all or part of any future payments to the RECIPIENT to offset any prior advance payments made to the RECIPIENT for ineligible expenditures that have not been refunded to the INSTITUTE by the RECIPIENT.

Section  3.07      Grant Funds as Supplement to Budget . The RECIPIENT shall use the Grant proceeds awarded pursuant to this Contract to supplement its overall budget. These funds will in no event supplant existing funds currently available to the RECIPIENT that have been previously budgeted and set aside for the Project. The RECIPIENT will not bill the INSTITUTE for any costs under this Contract that also have been billed or should have been billed to any other funding source.

Section  3.08      Buy Texas . The RECIPIENT shall apply good faith efforts to purchase goods and services from suppliers in Texas to the extent reasonably possible, to achieve a goal of more than 50 percent of such purchases from suppliers in Texas.

Section  3.09      Historically Underutilized Businesses . The RECIPIENT shall use reasonable efforts to purchase materials, supplies or services from a Historically Underutilized Business (HUB). The Texas Procurement and Support Services website will assist in finding HUB vendors (http://www.window.state.tx.us/procurement.) The RECIPIENT shall complete a HUB report with each annual report submitted to the INSTITUTE in accordance with Attachment E.

Section  3.10      Limitation on Use of Grant Award Proceeds to Pay Indirect Costs . The RECIPIENT shall not spend more than five percent of the Grant award proceeds for Indirect Costs.

Section  3.11      Carry Forward of Unspent Funds and No Cost Extension . RECIPIENT may request to carry forward unspent funds into the budget for the next year. Carryover of unspent funds must be specifically approved by the INSTITUTE. The INSTITUTE may approve a no cost extension for the Contract for a period not to exceed six (6) months after the Termination Date if additional time beyond the Termination date is required to ensure adequate completion of the approved project. The Contract must be in good fiscal and programmatic standing. All terms and conditions of the Contract shall continue during any extension period and if such extension is approved, notwithstanding Section 2.03, all references to the “Termination Date” shall be deemed to mean the date of expiration of such extension period.

The RECIPIENT, each Collaborator whose costs are funded in all or in part by the Grant shall maintain or cause to be maintained books, records, documents and other evidence (electronic or otherwise) pertaining in any way to its performance under and compliance with the terms and conditions of this Contract (“ Records ”).

Section  4.05      Duty to Resolve Deficiencies . If an audit and/or inspection under this Article IV finds there are deficiencies that should be remedied, then the RECIPIENT shall resolve and/or cure such deficiencies within a reasonable time frame specified by the INSTITUTE. Failure to do so shall constitute an Event of Default pursuant to Section 8.03 “Event of Default.” Upon the RECIPIENT’S request, the parties agree to negotiate in good faith, specific extensions so that the RECIPIENT can cure such deficiencies.

Section  4.06      Repayment of Grant Proceeds for Improper Use . In no event shall RECIPIENT retain Grant funds that have not been used by the RECIPIENT for purposes for which the Grant was intended or in violation of the terms of this Contract. The RECIPIENT shall repay any portion of Grant proceeds used by the RECIPIENT for purposes for which the Grant was not intended, as determined by the final results of an audit conducted pursuant to the provisions of this Contract. Unless otherwise expressly provided for in writing and appended to this Contract, the repayment shall be made to the INSTITUTE no later than forty-five (45) days upon a written request by the INSTITUTE specifying the amount to be repaid and detailing the basis upon which such request is being made and the amount shall include interest calculated at an amount not to exceed five percent (5%) annually.

If the INSTITUTE intends to terminate for an Event of Default under Section 8.01(b) by the RECIPIENT, as described in Section 8.03 “Event of Default”, the INSTITUTE shall provide written notice to the RECIPIENT pursuant to Section 9.21 “Notices” and shall include a reasonable description of the Event of Default and, if applicable, the steps necessary to cure such Event of Default.

Abstract and Significance

Multiple myeloma accounts for 10% of all hematological malignancies in the United States. An estimated 26,850 people were diagnosed with the disease in the United States in 2015 with an estimated 11,200 deaths resulting from the disease (SEER Cancer Statistics, 2015). The five-year survival rate for myeloma is only 45%.

Historically, there have been three major classes of therapeutics used to treat multiple myeloma: steroids, proteasome inhibitors, and the thalidomide-derived immunomodulatory drugs (IMiDs). In 2015, daratumumab, an antibody to CD38, and elotuzumab, an antibody to CS1, became the first biologics approved for multiple myeloma. Daratumumab in particular has shown robust single-agent activity (29% response rate) in relapsed/refractory patients indicating that CD38 plays an important role in myeloma disease progression.

Because of the generally poor outcome in myeloma patients, there is a high need for new therapeutics to treat the disease. Molecular Templates has developed a novel scaffold of biologics against cancer by fusing the single chain variable fragment of an antibody (scFv) to a proprietarily modified form of the Shiga-like toxin A subunit (SLTA), an enzymatic inactivator of ribosome activity. These compounds combine the specificity of an antibody with a novel and potent direct mechanism of cell-kill. Molecular Templates’ first compound, MT-3724 targets CD20 and is in a first-in-human dose-escalation study at MD Anderson and Memorial Sloan Kettering in heavily pre-treated patients with non-Hodgkins lymphoma (NHL). To date, there have been twelve patients treated with no dose-limiting toxicities seen. Of the eleven patients evaluable for efficacy, there has been one complete metabolic response (patient to undergo allogeneic transplant), one partial response, one mixed response, three stable diseases (all with tumor regression), and five patients with progressive disease. This efficacy is especially impressive since MT-3724 has not yet reached linear pharmacokinetics in its dose escalation.

Molecular Templates has designed MT-4019ND for the treatment of multiple myeloma. MT-4019ND has a high-affinity scFv that specifically targets CD38 fused to a proprietary de-immunized form of SLTA. MT-4019ND has shown extremely potent in vitro and in vivo activity against tumor cells expressing CD38. MT-4019ND has shown potent synergistic activity in combination with pomalidomide, the standard of care for refractory myeloma patients. MT-4019ND mirrors MT-3724 in terms of scaffold construction with similar absorption, distribution, metabolism and excretion (ADME) and pharmacokinetics (PK) characteristics.

CD38 was chosen as a target because of the clinical activity of daratumumab. Daratumumab works primarily by directing complement dependent cytotoxicity (CDC) and antibody-dependent cell-mediated cytotoxicity (ADCC) to CD38+ myeloma cells. Although immune recruitment can be a potent mechanism of cell-kill, roughly 70% of CD38+ refractory patients fail to respond to daratumumab monotherapy.

There is strong precedence in oncology for developing different mechanisms of action against the same validated target. There is an approved antibody, small molecule, and antibody-drug conjugate targeting HER2 in breast cancer, for example as well as multiple small molecules and antibodies to EGFR. In multiple myeloma, three different IMiDs (lenalidomide, pomalidomide, and thalidomide) are used sequentially in treatment. MT-4019ND was engineered to provide a different mechanism of destruction targeting CD38+ myelomas. In in vitro and in vivo studies, MT-4019ND shows excellent specificity, potency and safety as well as synergistic activity in combination with an IMiD. MT-3724 is administered as an infusion and has predictable PK and ADME characteristics. MT-4019ND shares a scaffold with MT-3724 which has shown excellent safety and notable efficacy in its first-in-human study.

pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended.

This application outlines a strategy to move MT-4019ND into clinical studies and rapidly characterize its activity in myeloma patients with no other treatment options. The development plan outlined in this application follows that of daratumumab and has the potential to show early signs of safety and efficacy and to form the basis of an accelerated FDA approval. Molecular Templates has successfully demonstrated that it can efficiently move pre-clinical leads into first-in-human studies. The early clinical data seen the company’s lead compound MT-3724 strongly suggest the scaffold used to construct MT-4019ND is safe and effective.

Layperson’s Summary

In 2015, there were approximately 27,000 new cases of multiple myeloma diagnosed in the US making it the second most prevalent blood cancer. The five-year survival rate for multiple myeloma is 45% and the median survival is approximately 4 years.

CD38 is a protein expressed on the surface of myeloma cells. Recently, daratumumab, an antibody that specifically targets CD38, was approved for the treatment of patients with multiple myeloma. Daratumumab works primarily by binding myeloma cells and recruiting an immune response to them. Most patients’ immune system will ultimately stop responding to daratumumab allowing the disease to progress.

Molecular Templates, a venture-backed biopharmaceutical company in Georgetown, TX, has developed a novel multiple myeloma drug that targets CD38 but works in a different way from daratumumab. MT-4019ND is a fusion of an antibody fragment that binds CD38 with a highly toxic bacterial protein. MT-4019ND binds CD38 on the surface of myeloma cells but instead of recruiting an immune response, it directly kills the myeloma cell through its toxin component. MT-4019ND has shown a potent ability to kill myeloma cell lines in the laboratory and in animal models of myeloma. Molecular Templates has a similar compound in the clinic for lymphoma that appears safe and effective in patients.

Molecular Templates seeks $15.3M in CPRIT financing to move MT-4019ND through clinical studies in patients with refractory multiple myeloma.

Section D3.02      Commercialization Efforts . The RECIPIENT shall, including whether through its own efforts or the efforts of a licensee under a License Agreement allowed by the terms of this Attachment, use diligent and commercially reasonable efforts to commercialize at least one Commercial Product or Commercial Service or otherwise bring to practical application the Project Results in accordance with the commercial development plan submitted with the Application and including any changes to such commercial development plan in accordance with Section D3.01. For the avoidance of doubt, partnering or licensing activities shall be considered to be efforts to commercialize.

Section D3.03      Licensing of Project Results . Each License Agreement entered into by the RECIPIENT shall include an acknowledgement by the licensee that (i) such License Agreement is subject to the INSTITUTE’s licenses, interests and other rights under this Contract, and (ii) to the extent that there is a conflict between the terms of the License Agreement and the terms of this Contract, the terms of this Contract shall prevail. In addition, all License Agreements shall include terms obligating the licensee to report to the RECIPIENT such information as is required for the RECIPIENT to fully comply with the terms of the Contract, including without limitation the reporting obligations set forth in Attachment E, and to allow RECIPIENT to make the grants specified in Sections D2.02.

Such written notice must identify the Project Results and provide a reasonable explanation of the reasons for the RECIPIENT’s election. Upon receipt of such notice, the INSTITUTE and RECIPIENT shall meet within [***] to review the Project Results and rationale for the RECIPIENT’s election. Provided that RECIPIENT’s determination to cease its efforts was not based on material safety concerns related to the Project Results, the INSTITUTE and RECIPIENT shall engage in good faith negotiations regarding an alternative commercialization strategy and/or revenue sharing approach.

The INSTITUTE and RECIPIENT may consider, among other options, an award of equity in the RECIPIENT, expansion or modification of the Institute Funded Activity to cover other commercial products or commercial services being advanced by the RECIPIENT, or some combination thereof. Unless otherwise agreed, if the INSTITUTE and RECIPIENT are unable to achieve an alternative strategy or agreement within [***] of the RECIPIENT’s initial notice of election, and provided that RECIPIENT’s determination to cease its efforts was not based on material safety concerns related to the Project Results, the INSTITUTE shall have the right, but not the obligation, to exercise its rights in Section D5.01 in relation to the Project Results at the INSTITUTE’s expense. If the INSTITUTE elects to exercise its rights under Section D5.01 in relation to the Project Results, the INSTITUTE shall notify the RECIPIENT in writing within the later of [***] of INSTITUTE’s receipt of the RECIPIENT’s initial notice of election or [***] following a declaration by one of the Parties that good faith negotiations have failed.

For clarity, so long as the RECIPIENT is making efforts to commercialize at least one Commercial Product or Commercial Service, RECIPIENT shall have no obligation to provide the written notice as described in this Section D3.06.

PART 4

REVENUE SHARING

Section D4.01      Revenue Sharing Percentages . In consideration for the Grant Award Proceeds paid to the RECIPIENT by the INSTITUTE under the Contract:

a.    RECIPIENT shall pay to the INSTITUTE during the Revenue Term the following payments until the INSTITUTE receives the aggregate amount of four hundred percent (400%) of the Grant Award Proceeds:

(i)      a revenue sharing percentage of [***] of Revenue for Cumulative Revenue greater than [***] and less than or equal to [***];

(ii)     a revenue sharing percentage of [***] of Revenue for Cumulative Revenue greater than [***] and less than or equal to [***]; and

(iii)    a revenue sharing percentage of [***] of Revenue for Cumulative Revenue greater than [***].

For clarity, no payments will be made by the RECIPIENT to the INSTITUTE under this Section D4.01(a) until the Cumulative Revenue of the Recipient is greater than [***].

b. In the event the RECIPIENT and/or its licensee is required to obtain a license under Intellectual Property Rights of one or more Third Parties in order to make Sales of Commercial Products and/or Commercial Services in any given country (“ Participating License Sources ”), then the revenue sharing percentages set forth under Section D4.01(a)(i)-(iii) may be reduced by [***] for every [***] royalty paid to such Third Parties on Commercial Products and/or Commercial Services in such country, as applicable, provided that in no event will the payments otherwise due to the INSTITUTE under Section D4.01(a) be less than [***] of the payments that would be payable to the INSTITUTE absent the effects of this Section D4.01(b). By way of example, if the RECIPIENT is required to obtain such a license from a Third Party in a country wherein the RECIPIENT pays a [***] royalty for Intellectual Property Rights that cover Commercial Products and Commercial Services in such country, the revenue sharing percentages under Section D4.01(a)(i), (ii), and (iii) would be reduced to [***] in such country, respectively.

Section D4.02      Continued Revenue Sharing . In the event the INSTITUTE receives during the Revenue Term the aggregate amount of four hundred percent (400%) of the Grant Award Proceeds from the RECIPIENT, the RECIPIENT will continue to pay the INSTITUTE a revenue sharing percentage of one-half percent (0.5%) of Revenue for all Revenue generated during the remainder of the Revenue Term. For clarity, this revenue sharing percentage cannot be reduced as set forth in Section D4.01(b).

Section D4.03      Equity . Nothing herein prohibits the INSTITUTE from negotiating with the RECIPIENT for an equity share in the RECIPIENT in addition to or in lieu of the revenue sharing set forth in Sections D4.01 and D4.02, when mutually agreed to by the INSTITUTE and the RECIPIENT. But under no circumstances is the INSTITUTE obligated to negotiate for an equity share in the RECIPIENT in lieu of the revenue sharing set forth herein.

Section D4.04      Statements and Timing of Payments . All payments owed pursuant to this Part 4 shall be made to the Cancer Prevention and Research Institute of Texas, and are payable on or before the thirtieth day following the end of the calendar quarter in which the Revenue is received or, in the case of Section D4.05, the monetary recovery is received. For each payment specified in Sections D4.01 and D4.02, the payment shall be accompanied by a statement specifying for such calendar quarter: (i) the Contract to which the payment relates, (ii) the identities of, royalty percentages, and amounts actually paid to any Participating License Sources, (iii) the License Agreements, if any, to which the payment relates, (iv) the quantity of all Sales of each Commercial Product and Commercial Service since the last payment, if Sales are applicable to the current payment, (v) the gross consideration from all such Sales, if Sales are applicable to the current payment, and (vi) a calculation of the amount of the payment to the Cancer Prevention and Research Institute of Texas.

Section D4.05      Recoveries in Enforcement Actions . In the event that the RECIPIENT receives any monetary recovery from its enforcement of Institute-Funded IPR against infringement by a third party, then it shall pay to the State of Texas a share of such monetary recovery, including any punitive damages, less the documented fees and expenses that are directly associated with such enforcement and are paid by RECIPIENT to third parties, at the same rate and in the same manner as it shares Revenue pursuant to Sections D4.01 and D4.02 (including any adjustments allowed by Section D4.01(b)). For clarity, if the enforcement action is resolved by way of the execution of a License Agreement with the allegedly infringing third party and such License Agreement is consistent with this Part 4, then this Section D4.05 is not intended to apply to such License Agreement or the consideration specified therein.

Section D4.06      Revenue-Related Records . In addition to satisfying the requirements of Article IV of the Contract and Section E1.03 of Attachment E, the RECIPIENT shall keep complete and accurate Revenue-related records until the fourth anniversary of the date of the payment of the last payment owed hereunder, in sufficient detail to permit the INSTITUTE to confirm the accuracy of the statements delivered to the INSTITUTE under Section D4.04 and the calculation of the payments owed hereunder.

Section D4.07      Audit of Revenue-Related Records . Upon at least fifteen (15) days’ advance written notice, the RECIPIENT shall permit the INSTITUTE or its representatives or agents, at the INSTITUTE’s expense, to examine the Revenue-related records of the RECIPIENT pursuant to Section D4.06 once per calendar year during regular business hours for the purpose of and to the extent necessary to verify the RECIPIENT’s compliance with this Part 4. The rights of the INSTITUTE under this Section D4.07 shall terminate on the fourth anniversary of the date of the payment of the last payment owed hereunder. In the event that any such examination reveals an underpayment to the INSTITUTE of greater than [***] of the amounts previously paid by the RECIPIENT to the INSTITUTE, then the RECIPIENT shall reimburse the INSTITUTE for the cost of such examination.

PART 5

OPT-OUT AND DEFAULT

Section D5.01      RECIPIENT Opt-Out . If the INSTITUTE elects to exercise its rights in relation to the Project Results under Section D3.06, the INSTITUTE shall have the right, but not the obligation, to pursue protection of the Applicable Institute-Funded IPR on its own behalf, including directing the filing, prosecution and maintenance of patents covering the applicable Institute-Funded Inventions and/or to commercialize or otherwise bring to practical application Project Results covered by the Applicable Institute-Funded IPR, at its own cost, either directly or through one or more licensees. For the purposes of this Part 5, “Applicable Institute-Funded IPR” shall mean all Project Results. If the INSTITUTE elects to exercise any such rights under this Section D5.01, it shall notify RECIPIENT in writing pursuant to the notification requirements in Section D3.06 and RECIPIENT shall thereafter comply with the terms of Section D5.03 with regard to the Applicable Institute-Funded IPR.

Section D5.02      RECIPIENT Default. In the event that the INSTITUTE notifies RECIPIENT in writing of RECIPIENT’s failure to materially comply with its obligations under Section D3.02, and RECIPIENT fails within [***] of such notice either: (a) to cure such failure, or in the event that such failure cannot be reasonably cured within such [***] period, to provide to INSTITUTE a plan to cure such failure that INSTITUTE deems acceptable, (b) to provide written notice to the INSTITUTE that such failure was due to material safety concerns, or (c) to provide proper notice pursuant to Section 3.06, then without further action on the part of the RECIPIENT or INSTITUTE, the RECIPIENT shall be deemed to have provided the INSTITUTE the complete, written notice of its cessation of efforts as described in Section 3.06, and the INSTITUTE shall be free to exercise its rights under Section 3.06.

Section D5.03      RECIPIENT Cooperation upon Opt-Out or Default . In the event that the INSTITUTE exercises any of its rights under Section D5.01, the RECIPIENT shall:

If the INSTITUTE exercises its rights under Sections D5.01, the RECIPIENT shall have no further claim to or interest in the applicable Project Results, except as set forth in Section D2.01 of this Attachment and shall not be entitled to any share of Revenue or any other compensation with respect to such Project Results, except to the minimum extent required by law, if any. To the extent that the INSTITUTE has exercised its rights under Section D5.01 and RECIPIENT is unable to transfer all of its right, title and interest in and to the applicable Project Results to the INSTITUTE as specified in D5.03(1), then the INSTITUTE’s license set forth in D5.03(2) includes the right, but not the obligation, for the INSTITUTE at its cost to: (i) direct the filing, prosecution and maintenance of patents covering the applicable Project Results, and (ii) enforce all Applicable Institute-Funded IPR relevant to the Project Results against any infringement by a third party. Subject to the statutory duties of the Texas Attorney General, if any, RECIPIENT shall cooperate fully with the INSTITUTE in any action brought by the INSTITUTE to enforce the Institute-Funded IPR in the applicable Project Results, at the INSTITUTE’s cost, including without limitation, joining the enforcement action in name as a party plaintiff after all required approvals are obtained; provided that the INSTITUTE or its designee shall have full control over such enforcement action and shall receive and retain all monetary and other recoveries resulting from such enforcement actions, including any punitive damages.
