(v) amounts written off by reason of uncollectible bad debt, but not to exceed [***] percent ([***]%) of the gross amount billed by COMPANY and its AFFILIATES and SUBLICENSEES for LICENSED PRODUCTS and LICENSED PROCESSES in a given REPORTING PERIOD.

No deductions shall be made for commissions paid to individuals whether they be with independent sales agencies or regularly employed by COMPANY and on its payroll, or for cost of collections. NET SALES shall occur on the date of billing for a LICENSED PRODUCT or LICENSED PROCESS. If a LICENSED PRODUCT or LICENSED PROCESS is distributed at a discounted price that is substantially lower than the customary price charged by COMPANY, or distributed for non-monetary consideration (whether or not at a discount), NET SALES shall be calculated based on the non-discounted amount of the LICENSED PRODUCT or LICENSED PROCESS, as applicable, charged to an independent third party during the same REPORTING PERIOD or, in the absence of such sales, on the fair market value of the LICENSED PRODUCT or LICENSED PROCESS, as applicable. NET SALES shall not include sales or transfers of reasonable amounts of LICENSED PRODUCTS or LICENSED PROCESSES without consideration for use in clinical trials or compassionate, named patient, indigent patient or similar uses.

NET SALES will be calculated only once with respect to each LICENSED PRODUCT and LICENSED PROCESS sold by COMPANY, any AFFILIATE and/or any SUBLICENSEE, even if such LICENSED PRODUCT or LICENSED PROCESS is sold more than once in the course of its transfer to the ultimate end-user. The foregoing notwithstanding, the transfer or sale of LICENSED PRODUCTS or LICENSED PROCESSES between COMPANY and an AFFILIATE and/or SUBLICENSEE, e.g., in a manufacturing or supply arrangement, shall not be included in NET SALES, unless such transfer or sale is a final purchase by COMPANY, AFFILIATE or SUBLICENSEE, without the intent to further sell, transfer or distribute to a third party.

In the event that non-monetary consideration is received for any LICENSED PRODUCTS or LICENSED PROCESSES by COMPANY or any AFFILIATE or SUBLICENSEE, NET SALES shall be calculated based on the fair market value of such non-monetary consideration, including all elements of such consideration. The fair market value of any non-monetary consideration used to calculate NET SALES shall be determined in good faith by the Board of Directors of COMPANY and COMPANY shall provide M.I.T. with a summary of the analysis used to determine such fair market value ; provided, however, that if M.I.T. reasonably and in good faith disputes such fair market value as determined by the Board of Directors of COMPANY, the parties shall promptly meet to discuss in good faith M.I.T.’s concerns, and if the parties cannot come to a resolution, shall submit the matter to a mutually agreeable independent valuation firm for a binding determination of valuation. The parties shall share equally the reasonable costs and fees of such firm in connection with such determination.

For clarification, NET SALES shall be based upon the final sale price of the entire LICENSED PRODUCT or LICENSED PROCESS, as applicable, without reduction or allocation by component or technology, whether sold by COMPANY, its AFFILIATES or SUBLICENSEES. No combination product discounts are allowed.

NET SALES shall not include SUBLICENSE INCOME, which shall be subject to SUBLICENSE INCOME sharing under Section 4.1(f).

1.14. “PATENT CHALLENGE” shall mean a challenge to the validity, patentability and/or enforceability of any of the PATENT RIGHTS (as defined below) or otherwise opposing any of the PATENT RIGHTS.

1.15. “PATENT RIGHTS” shall mean:

No fees will be due for the addition of any patent application on the MIT/BCH INVENTION DISCLOSURE so added to this Agreement.

2.3 Sublicenses.

(a) COMPANY shall have the right to grant sublicenses of its rights under Section 2.1 through multiple tiers subject to this Section 2.3(a), and provided that, notwithstanding the foregoing, if COMPANY becomes a non-exclusive licensee under any PATENT RIGHT in any country pursuant to Section 6.1, or an amendment to this Agreement, then COMPANY shall no longer have the right to grant sublicenses under such PATENT RIGHT in such country.

In any sublicense agreement with a SUBLICENSEE, COMPANY may grant to such SUBLICENSEE the right to grant further sublicenses of the PATENT RIGHTS sublicensed by COMPANY to SUBLICENSEE (“SUBLICENSEE SUBLICENSED RIGHTS”) on the following terms and conditions:

(i) Each person or entity that has been granted a sublicense of the SUBLICENSEE SUBLICENSED RIGHTS, a “SUBLICENSEE SUBLICENSED PARTY,” shall be considered a “SUBLICENSEE” for the purposes of this Agreement.

(ii) Any consideration that COMPANY or an AFFILIATE receives from a SUBLICENSEE in consideration of the sublicense of the licenses and rights granted COMPANY and AFFILIATES under Section 2.1, including without limitation in connection with the sublicense of such rights to a SUBLICENSEE SUBLICENSED PARTY, shall be considered SUBLICENSE INCOME hereunder to the extent described in the definition of such term.

(iii) Any agreement pursuant to which a SUBLICENSEE grants a sublicense of the SUBLICENSEE SUBLICENSED RIGHTS (a “SUBLICENSEE SUBLICENSE AGREEMENT”) shall satisfy the requirements of this Section 2.3(a); notwithstanding and without limiting the foregoing, any SUBLICENSEE SUBLICENSE AGREEMENT shall include terms that are sufficient to enable COMPANY to comply with this Agreement.

(iv) COMPANY shall, and ensures that SUBLICENSEE shall (I) furnish M.I.T. with a fully signed copy of any SUBLICENSEE SUBLICENSE AGREEMENT promptly after it is executed, which agreement may be redacted solely to preserve any confidential information of the parties thereto, and to the extent that it does not impair M.I.T.’s ability to ensure compliance with this Agreement, and (II) deliver to M.I.T. reports containing the information described in Article 5 with respect to any SUBLICENSEE SUBLICENSED PARTY.

COMPANY shall incorporate terms and conditions into its sublicense agreements sufficient to enable COMPANY to comply with this Agreement. If COMPANY is no longer the exclusive licensee of any PATENT RIGHT(S) in the FIELD or in any subset of the FIELD (e.g., if M.I.T. grants a license to a third party under the PATENT RIGHTS pursuant to Section 3.1(g)), then any exclusivity granted by COMPANY under its sublicense agreements with respect to such PATENT RIGHT(S) in the FIELD or in any such subset of the FIELD, as applicable, shall expire and such sublicenses to such PATENT RIGHTS shall become non-exclusive. COMPANY shall also include provisions in all sublicenses to provide that in the event that SUBLICENSEE brings a PATENT CHALLENGE or assists another party in bringing a PATENT CHALLENGE (except as required under a court order or subpoena) then COMPANY may terminate the sublicense.

COMPANY shall not structure sublicensing arrangements for the PATENT RIGHTS, either alone or in connection with other assets (e.g., technology and/or intellectual property rights) owned or controlled by COMPANY and/or an AFFILIATE in a single transaction or series of related transactions, in order to minimize or avoid payments to MIT for SUBLICENSE INCOME sharing under this Agreement. In the event that non-monetary consideration is received for any sublicense of the PATENT RIGHTS, SUBLICENSE INCOME shall be calculated based on the fair market value of such non-monetary consideration, including all elements of such consideration. The fair market value of any non-monetary consideration received by COMPANY in consideration of any sublicense hereunder shall be determined in good faith by the Board of Directors of COMPANY and COMPANY shall provide M.I.T. with a summary of the analysis used to determine such fair market value; provided, however, if M.I.T. reasonably and in good faith disputes such fair market value as determined by the Board of

Directors of COMPANY, the parties shall promptly meet to discuss in good faith M.I.T.’s concerns, and if the parties cannot come to a resolution, shall submit the matter to a mutually agreeable independent valuation firm for a binding determination of valuation. The parties shall share equally the reasonable costs and fees of such firm in connection with such determination. For the avoidance of doubt, (1) customary grant-back licenses and/or assignments of intellectual property with respect to improvements to the technology covered by the PATENT RIGHTS or the right to market and sell LICENSED PRODUCTS and/or LICENSED PROCESSES (e.g., co-promotion rights) and (2) diligence or other customary obligations from any SUBLICENSEE to COMPANY shall not be considered non-monetary consideration for a sublicense of the PATENT RIGHTS if such rights or obligations are granted or owed by a SUBLICENSEE to COMPANY in connection with reasonable, bona fide monetary consideration or securities in consideration of the grant of the sublicense agreement.

COMPANY shall promptly furnish M.I.T. with a copy of each sublicense agreement and any subsequent amendments thereof, which agreement may be redacted solely to preserve any confidential information of the parties thereto, and to the extent that it does not impair M.I.T.’s ability to ensure compliance with this Agreement.

(b) Sublicense Survival. In the event of termination of this Agreement by M.I.T., except pursuant to Section 12.5(b), M.I.T. agrees that, after the effective date of termination of this Agreement, each SUBLICENSEE shall be entitled to become a direct licensee of M.I.T. under the PATENT RIGHTS, provided that:

(1) Within [***] days of the effective date of termination of this Agreement, SUBLICENSEE and M.I.T. shall execute a new license agreement on substantially the same terms set forth in this Agreement as set forth in Section 2.3(b)(5) below (the “NEW LICENSE AGREEMENT”);

(2) M.I.T. shall not be obligated to grant to any such SUBLICENSEE any rights under the PATENT RIGHTS that are broader than the rights previously granted by COMPANY to SUBLICENSEE, or inconsistent with the rights granted to COMPANY under this Agreement;

(3) SUBLICENSEE is not in material breach under the sublicense agreement with COMPANY, or in default of any relevant provisions of this Agreement, at the date of termination of this Agreement;

(4) Unless otherwise agreed to in writing by M.I.T. and the SUBLICENSEE under the NEW LICENSE AGREEMENT, SUBLICENSEE shall be obligated to pay M.I.T. all of the payments M.I.T. would have been entitled to receive from COMPANY under Article 4 of this Agreement, including without limitation running royalties (Section 4.1(d)), and milestone payments (Section 4.1(e)) specified in this Agreement, as well as sharing of SUBLICENSE INCOME (Section 4.1(f)) and reimbursement of future PATENT EXPENSES (Sections 4.1(a) and 6.3), in each case as if the sublicense agreement between COMPANY and SUBLICENSEE and this Agreement were both still in full effect. For example, for a given milestone event achieved under Section 4.1(e) of this Agreement, the NEW LICENSE AGREEMENT shall require payment of the applicable amounts due under both Sections 4.1(e) and 4.1(f), with respect to consideration that would otherwise have been SUBLICENSE INCOME, of this Agreement, as if the sublicense agreement between COMPANY and SUBLICENSEE was still in full effect; and

(5) The NEW LICENSE AGREEMENT shall include substantially identical terms and conditions of the following provisions of this Agreement:

Subject to Sections 2.3(b)(2) above, Section 2.1 (License Grants);

Section 2.3(a) (Sublicenses);

Section 2.4 (U.S. Manufacturing);

Section 2.5 (Retained Rights);

Section 3.1 (Diligence Requirements);

Section 4.1(g) (Consequences of a PATENT CHALLENGE);

Article 5 (Reports and Records);

Section 6.1 (Responsibility for PATENT RIGHTS);

Section 6.3 (Payment of Expenses), provided that responsibility for payment of PATENT EXPENSES shall be equitably apportioned among all SUBLICENSEES of the PATENT RIGHTS that enter into a NEW LICENSE AGREEMENT with M.I.T.;

Article 7 (Infringement);

Article 8 (Indemnification and Insurance);

Article 9 (Representations or Warranties);

Article 11 (General Compliance with Laws);

Section 12.3 (Cessation of Business; Insolvency);

Section 12.4 (Termination for Default);

Section 12.5 (Termination as a Consequence of a PATENT CHALLENGE);

Article 13 (Dispute Resolution);

Section 15.1 (Notice); and

Section 15.2 (Governing Law and Jurisdiction).

2.4 U.S. Manufacturing. COMPANY agrees to comply with the requirements of 35 U.S.C. §204 “Preference for United States Industry,” as amended, or any successor statutes or regulations.

2.5 Retained Rights.

(a) Research and Educational Use. M.I.T. and BCH retain the right on behalf of themselves and all other non-profit research institutions to practice under the PATENT RIGHTS for non-profit research, teaching, and educational purposes, including sponsored research and collaborations.

(b) Federal Government. COMPANY acknowledges that the U.S. federal government retains a royalty-free, non-exclusive, non-transferable license to practice any government-funded invention claimed in any PATENT RIGHTS as set forth in 35 U.S.C. §§ 201-211, and the regulations promulgated thereunder, as amended, or any successor statutes or regulations.

2.6 No Additional Rights. Subject to Section 2.2, nothing in this Agreement shall be construed to confer any rights upon COMPANY by implication, estoppel, or otherwise as to any technology or patent rights of M.I.T. or any other entity other than the PATENT RIGHTS, regardless of whether such technology or patent rights shall be dominant or subordinate to any PATENT RIGHTS.

3. COMPANY DILIGENCE OBLIGATIONS.

3.1 Diligence Requirements. COMPANY shall use commercially reasonable efforts, or shall cause its AFFILIATES to use commercially reasonable efforts, to develop LICENSED PRODUCTS or LICENSED PROCESSES and to introduce LICENSED PRODUCTS or LICENSED PROCESSES into the commercial market; thereafter, COMPANY or its AFFILIATES shall make LICENSED PRODUCTS or LICENSED PROCESSES reasonably available to the public. Specifically, COMPANY or AFFILIATE shall fulfill the following obligations:

(a) Within [***] months after the EFFECTIVE DATE, COMPANY shall furnish M.I.T. with a written research and development plan describing the major tasks to be achieved in order to bring to market a LICENSED PRODUCT or a LICENSED PROCESS, specifying the resources intended to be devoted to such commercialization effort.

(b) Within [***] year of the EFFECTIVE DATE, COMPANY shall use commercially reasonable efforts to evaluate the PATENT RIGHTS with a view toward creating a LICENSED PRODUCT and/or LICENSED PROCESS for the treatment and/or prevention of diabetes and/or its complications in humans.

(c) Within [***] days after the end of each calendar year, COMPANY shall furnish M.I.T. with a written report (consistent with Section 5.1(a)) on the progress of its efforts during the immediately preceding calendar year to develop and commercialize LICENSED PRODUCTS or LICENSED PROCESSES. The report shall also contain any updates to the research and development plan as well as a discussion of intended efforts, if applicable, for the year in which the report is submitted.

(d) Fundraising.

(i) COMPANY shall raise at least [***] by [***] from the sale of equity securities for its own account; and

(ii) In the aggregate, COMPANY shall raise at least [***] by the [***] year anniversary of the EFFECTIVE DATE from (1) the sale of equity securities for its own account, (2) grants from government or non-government sources or (3) SUBLICENSE INCOME.

(e) COMPANY shall expend at least the amounts set forth below on research and/or development of LICENSED PRODUCTS and/or LICENSED PROCESSES in each [***] month period listed below and ending with the FIRST COMMERCIAL SALE of the first LICENSED PRODUCT or LICENSED PROCESS (the final [***] month period of which shall be pro-rated):

[*] months ending on the [*] anniversary of the EFFECTIVE DATE	$	[***]
[*] months ending on the [*] anniversary of the EFFECTIVE DATE	$	[***]
[*] months ending on the [*] anniversary of the EFFECTIVE DATE	$	[***]
[*] months ending on the [] anniversary of the EFFECTIVE DATE and every [**] month period thereafter	$	[***]

(f) THERAPEUTIC PRODUCTS.

(1) Within [***] years of the EFFECTIVE DATE, advance a DEVELOPMENT CANDIDATE for a THERAPEUTIC PRODUCT to appropriate studies in support of an Investigational New Drug application (“IND”) (or equivalent) for human studies.

(2) Within [***] years of the EFFECTIVE DATE, file an IND for a THERAPEUTIC PRODUCT.

(3) Within [***] years of the EFFECTIVE DATE, commence dosing of individuals in a PHASE I CLINICAL TRIAL for a THERAPEUTIC PRODUCT.

(4) Within [***] years of the EFFECTIVE DATE, commence dosing of individuals in a PHASE III CLINICAL TRIAL for a THERAPEUTIC PRODUCT.

(5) Within [***] years of the EFFECTIVE DATE, make a FIRST COMMERCIAL SALE of a THERAPEUTIC PRODUCT.

(g) MANDATORY SUBLICENSING. If, at any time after [***] years from the EFFECTIVE DATE, M.I.T. or COMPANY receives a bona fide request from a third party seeking a license under the PATENT RIGHTS to develop and commercialize a LICENSED PRODUCT and/or LICENSED PROCESS within one or more subsets of the FIELD (the “PROPOSED PRODUCT”), then the party receiving such inquiry will (i) obtain a written summary of the request from such third party, and (ii) upon receipt of such written request, promptly notify the other party in writing within [***] days of such inquiry (a “PATENT RIGHTS INQUIRY NOTICE”), setting forth the specific PATENT RIGHTS desired, the name

and contact information of the third party, the PROPOSED PRODUCT, and any other pertinent information relevant to the PROPOSED PRODUCT. Within [***] months after the date of receipt of a PATENT RIGHTS INQUIRY NOTICE, COMPANY shall:

(i) reasonably demonstrate to M.I.T. that (1) the PROPOSED PRODUCT would be directly competitive with a LICENSED PRODUCT or LICENSED PROCESS for which COMPANY or an AFFILIATE or SUBLICENSEE has already begun a FULLY FUNDED PROJECT and is diligently developing, (2) COMPANY, or an AFFILATE or SUBLICENSEE, has already begun a FULLY FUNDED PROJECT and is diligently researching, developing and/or commercializing the PROPOSED PRODUCT, or (3) based on competent evidence, such evidence to be provided to M.I.T., the third party does not have adequate financial and/or scientific resources, nor a reasonable strategy and/or ability to acquire same, to develop and commercialize such PROPOSED PRODUCT; or

(ii) provide M.I.T. with a business plan with mutually acceptable, reasonable diligence milestones (such diligence milestones to be added by amendment to this Agreement) for the commercial development of the PROPOSED PRODUCT, which shall include commencing a FULLY FUNDED PROJECT for the PROPOSED PRODUCT within [***] months of receipt of the PATENT RIGHTS INQUIRY NOTICE; or

(iii) negotiate in good faith with such third party and enter into a sublicense agreement containing commercially reasonable terms and conditions for the requested PATENT RIGHTS for the PROPOSED PRODUCT. Notwithstanding the foregoing, in the event that COMPANY and the third party continue to make reasonable progress in such negotiations, COMPANY may request to extend the [***] month period, as needed, for up to an additional [***] months to conclude such negotiations. COMPANY shall continue such negotiations in good faith until the earliest of (a) entering into such a sublicense agreement, (b) being notified by such third party that it no longer wishes to enter into such a sublicense for the PROPOSED PRODUCT, or (c) determining in good faith that continuing such negotiations will not reasonably lead to an agreement on the terms of such a sublicense. In the event that COMPANY discontinues negotiations pursuant to clause (c) above, COMPANY shall notify M.I.T. in writing and the parties shall meet to discuss the implications with respect to this Section 3.1(g).

If COMPANY does not perform any one of the foregoing three actions within [***] months after the date of receipt of a PATENT RIGHTS INQUIRY NOTICE, then M.I.T., at its sole discretion, may grant a license to such third party under the PATENT RIGHTS for the applicable PROPOSED PRODUCT within the applicable subset(s) of the FIELD, and upon the effective date of such license, COMPANY’s and AFFILIATE’s rights under the PATENT RIGHTS for the applicable PROPOSED PRODUCT within the FIELD shall be terminated, and this Agreement shall be amended to reflect the same. For the avoidance of doubt, COMPANY’s rights under the PATENT RIGHTS for all uses other than for the applicable PROPOSED PRODUCT within the FIELD shall remain in accordance with the terms of this Agreement.

Notwithstanding the foregoing, in the event that COMPANY is able to negotiate a sublicense agreement with a third party pursuant to this Section 3.1(g), and believes that the financial terms of such sublicense agreement are economically infeasible to COMPANY, for example, in view of COMPANY’s financial obligations to M.I.T. under this Agreement, COMPANY may notify M.I.T. in writing, providing a negotiated term sheet or substantially final draft of such sublicense agreement and the reasons why COMPANY believes the financial terms thereof to be infeasible (an “EXCEPTION NOTICE”), and the parties shall meet to discuss in good faith an adjustment to the financial terms of this Agreement solely as would apply to such sublicense agreement. COMPANY and M.I.T. will enter into a written amendment to this Agreement with respect to any mutually agreed upon change(s) to the relevant financial obligation(s) with respect to such sublicense agreement. If COMPANY and M.I.T. do not enter into an amendment with respect to the proposed sublicense agreement between COMPANY and such third party within [***] business days of M.I.T.’s receipt of an EXCEPTION NOTICE, and COMPANY therefore does not enter into such sublicense agreement, then, in the event that M.I.T. grants a license to such third party in accordance with this Section 3.1(g), M.I.T. shall not have the right to grant such license on financial terms the same as or any less favorable, in aggregate, than those offered to the third party by COMPANY and discussed with M.I.T. pursuant to the EXCEPTION NOTICE.

In the event that M.I.T. determines that COMPANY (or an AFFILIATE) has failed to fulfill any of its obligations under this Section 3.1, then M.I.T. may treat such failure as a material breach in accordance with Section 12.4(b), subject to Section 3.2 below. Notwithstanding the foregoing, any termination under Section 12.4(b) for breach of obligations under Section 3.1(b) shall be limited to COMPANY’s and its AFFILIATE’s licenses and rights under the PATENT RIGHTS in the DIABETES SUBFIELD. The termination of COMPANY’s

and AFFILIATE’s licenses and rights in the DIABETES SUBFIELD will not affect the remaining terms of this Agreement.

3.2 Changes to Diligence Requirements. In the event that COMPANY anticipates that a failure to meet an obligation set forth in Section 3.1(f) will occur, COMPANY will promptly notify M.I.T. in writing, and representatives of each party will meet to review the reasons for anticipated failure and discuss in good faith a potential revision to the diligence schedule.

In addition to the foregoing, if COMPANY provides written notice and reasonably demonstrates to M.I.T. that the anticipated failure to meet any one of the diligence obligations set forth in Section 3.1(f) is due to (i) an action, inaction, delay or ruling by the United States Food and Drug Administration or any comparable regulatory agency, or (ii) the existence of material technical or scientific difficulties or delays in pre-clinical or clinical studies (e.g., unfavorable toxicological or pharmacological test results or an adverse clinical event with respect to LICENSED PRODUCTS or LICENSED PROCESSES) that COMPANY or a SUBLICENSEE could not reasonably have predicted and/or avoided (each of (i) and (ii), a “DEVELOPMENT ISSUE”), then the parties shall meet to review the cause and nature of the DEVELOPMENT ISSUE as well as COMPANY’s proposed plan and timeline to address same, and the parties shall reasonably amend the relevant aspects of the diligence schedule to account for such DEVELOPMENT ISSUE.

COMPANY and M.I.T. will enter into a written amendment to this Agreement with respect to any mutually agreed upon change(s) to the relevant obligation.

4. ROYALTIES AND PAYMENT TERMS.

4.1 Consideration for Grant of Rights.

(a) License Issue Fee and Patent Cost Reimbursement. COMPANY shall pay to M.I.T. within [***] business days following the EFFECTIVE DATE a license issue fee of [***]. In addition, in accordance with Section 6.3, COMPANY shall reimburse M.I.T. for its actual expenses incurred as of the EFFECTIVE DATE in connection with obtaining the PATENT RIGHTS. These payments are nonrefundable.

(b) Option Fee and Patent Cost Reimbursement. COMPANY shall reimburse M.I.T. within [***] business days following the EFFECTIVE DATE in the amount of [***] for its actual expenses incurred as of the EFFECTIVE DATE in connection with obtaining the patent

rights set forth in Appendix C. In addition, within [***] days after M.I.T. invoices COMPANY, COMPANY shall reimburse M.I.T. for all reasonable patent-related expenses (including attorneys’ fees) incurred by M.I.T. during the OPTION PERIOD in connection with obtaining or maintaining the patent rights set forth in Appendix C.

(c) License Maintenance Fees. COMPANY shall pay to M.I.T. the following license maintenance fees on the dates set forth below:

[***]	$	[***]
[***]	$	[***]
[***]	$	[***]
[***]	$	[***]
[***]	$	[***]
[***]	$	[***]
[***]	$	[***]

This annual license maintenance fee is nonrefundable; however, the license maintenance fee may be credited to running royalties subsequently due on NET SALES earned during the same calendar year, if any. License maintenance fees paid in excess of running royalties due in such calendar year shall not be creditable to amounts due for future years.

(d) Running Royalties.

(i) THERAPEUTIC PRODUCTS. On a THERAPEUTIC PRODUCT-by-THERAPEUTIC PRODUCT and country-by-country basis, COMPANY shall pay to M.I.T. a running royalty of [***] percent ([***]%) of NET SALES of THERAPEUTIC PRODUCTS during the applicable ROYALTY TERM therefor.

(ii) DIAGNOSTIC PRODUCTS. On a DIAGNOSTIC PRODUCT-by-DIAGNOSTIC PRODUCT and country-by-country basis, COMPANY shall pay to M.I.T. a running royalty of [***] percent ([***]%) of NET SALES of DIAGNOSTIC PRODUCTS during the applicable ROYALTY TERM therefor.

Running royalties shall be payable for each REPORTING PERIOD and shall be due to M.I.T. within [***] days of the end of each REPORTING PERIOD.

(iii) Royalty Offset. If COMPANY or an AFFILIATE is required to pay royalties to one or more third parties in order to obtain a license or similar right necessary to make, use, or sell THERAPEUTIC PRODUCTS, COMPANY shall be entitled to credit up to [***] percent ([***]%) of the amounts actually paid by COMPANY or an AFFILIATE to such third parties for a THERAPEUTIC PRODUCT against the royalties due to M.I.T. under Section 4.1(d)(i) of this Agreement and up to [***] percent ([***]%) of the amounts actually paid by COMPANY or an AFFILIATE to such third parties for a DIAGNOSTIC PRODUCT against the royalties due to M.I.T. under Section 4.1(d)(ii) of this Agreement, in each case the same REPORTING PERIOD; provided, however, that (i) in no event will the royalties due to M.I.T. under Section 4.1(d)(i), when aggregated with any other offsets and credits allowed under this Agreement, be less than [***] percent ([***]%) of NET SALES of THERAPEUTIC PRODUCTS in any REPORTING PERIOD, (ii) in no event will the royalties due to M.I.T. under Section 4.1(d)(ii), when aggregated with any other offsets and credits allowed under this Agreement, be less than [***] percent ([***]%) of NET SALES of DIAGNOSTIC PRODUCTS in any REPORTING PERIOD, and (iii) payment of royalties by COMPANY or an AFFILIATE to such third party(ies) are required to be offset as a result of royalties payable to M.I.T. for THERAPEUTIC PRODUCTS by at least the same percentage as M.I.T. has offset its royalties under this Section 4.1(d)(iii). If in any REPORTING PERIOD, COMPANY is not able to fully recover the [***] percent ([***]%) portion or [***] percent ([***]%) portion, as applicable, of the payments due to such third party(ies) through a reduction in royalties hereunder as a result of the limitations in this Section 4.1(d)(iii), COMPANY shall be entitled to carry forward such right to offset to future REPORTING PERIODS with respect to the excess amount.

(e) Milestone Payments. COMPANY shall pay to M.I.T. the amounts set forth below upon the achievement by COMPANY or an AFFILIATE or SUBLICENSEE of certain milestone events as described below.

(1) THERAPEUTIC PRODUCTS.

Milestone Event	Payment
[***]	$	[***]
[***]	$	[***]
[***]	$	[***]
[***]	$	[***]

Notwithstanding the foregoing, if a THERAPEUTIC PRODUCT is a medical device that is not regulated as a drug, then the milestones due for such THERAPEUTIC PRODUCT shall be as follows:

Milestone Event	Payment
[***]	$	[***]
[***]	$	[***]
[***]	$	[***]

(2) DIAGNOSTIC PRODUCTS.

Milestone Event	Payment
[***]	$	[***]
[***]	$	[***]
[***]	$	[***]
[***]	$	[***]

Payments will be only due in respect of the first achievement of the milestone events in the tables above for the first [***] THERAPEUTIC PRODUCTS and DIAGNOSTIC PRODUCTS, respectively.

The milestone events set forth above are intended to be successive. In the event that any milestone is reached without achieving a preceding milestone, then the amount which would have been payable on achievement of the preceding milestone shall also be payable upon achievement of the next successive milestone.

COMPANY shall notify M.I.T. within [***] days of the achievement of any of the above milestones by COMPANY or any of its SUBLICENSEES, such notice to specifically identify the payment obligation. COMPANY shall make such non-creditable, non-refundable milestone payments within [***] days after receipt of an invoice from M.I.T. for same.

(f) Sharing of SUBLICENSE INCOME. COMPANY shall pay M.I.T. the percentage of all SUBLICENSE INCOME received by COMPANY or its AFFILIATES based on the date of execution of the sublicense agreement as set forth below:

Date of execution of the sublicense agreement	Percentage of SUBLICENSE INCOME due to M.I.T.
[***]	[***]	%
[***]	[***]	%
[***]	[***]	%

For clarity, for purposes of this Section 4.1(f), [***]. Notwithstanding the foregoing, in the event that a given sublicense agreement covers only DIAGNOSTIC PRODUCTS (and not THERAPEUTIC PRODUCTS), then COMPANY shall pay M.I.T. a total of [***] percent ([***]%) of all SUBLICENSE INCOME received by COMPANY or AFFILIATES in connection with such DIAGNOSTIC PRODUCT sublicense agreement.

Such amounts shall be payable for each REPORTING PERIOD and shall be due to M.I.T. within [***] days of the end of each REPORTING PERIOD.

(g) Consequences of a PATENT CHALLENGE. In the event that (i) COMPANY or any of its AFFILIATES brings a PATENT CHALLENGE, or (ii) COMPANY or any of its AFFILIATES assists another party in bringing a PATENT CHALLENGE (except as required under a court order or subpoena), and (iii) M.I.T. does not choose to exercise its rights to terminate this Agreement pursuant to Section 12.5, then all payments due under Article 4 shall be [***] for the remainder of the TERM. In the event that such a PATENT CHALLENGE is successful, COMPANY will have no right to recoup any royalties paid during the period of challenge. In the event that a PATENT CHALLENGE is unsuccessful, COMPANY shall reimburse M.I.T. for all reasonable legal fees and expenses incurred in its defense against the PATENT CHALLENGE.

(h) Equity.

(i) Initial Grant. COMPANY shall issue to M.I.T. and BCH (each a “SHAREHOLDER” and collectively the “SHAREHOLDERS”), as M.I.T. shall direct, a total of [***] shares of Common Stock of COMPANY, $.001 par value per share, (the “SHARES”). M.I.T. and BCH shall execute an investment letter in a form mutually agreeable to M.I.T., BCH and COMPANY in connection with such issuance. Such issuances shall be recorded on the Stock Transfer Ledger of COMPANY on the EFFECTIVE DATE and stock certificates representing

the SHARES shall be delivered to the Shareholders within [***] days of the EFFECTIVE DATE.

COMPANY represents to M.I.T. that, as of the EFFECTIVE DATE, the aggregate number of SHARES equals [***] Percent ([***]%) of COMPANY’s issued and outstanding Common Stock calculated on a “FULLY DILUTED BASIS”. For purposes of this Section 4.1(h), “FULLY DILUTED BASIS” shall mean the total number of issued and outstanding shares of COMPANY’s Common Stock calculated to include conversion of all issued and outstanding securities convertible into Common Stock, the exercise of all outstanding options and warrants to purchase shares of Common Stock whether or not then exercisable, the conversion or exercise of all rights to purchase or acquire Common Stock, whether or not then convertible or exercisable, and shall assume the issuance or grant of all securities reserved for issuance pursuant to any COMPANY stock or stock option plan in effect on the date of the calculation.

(ii) Anti-Dilution Protection Through Funding Threshold. COMPANY from time to time shall issue additional shares of Common Stock to the Shareholders, pro rata in accordance with their respective ownership of the SHARES, as may be necessary to ensure that the SHARES (together with any and all shares issued pursuant to this Section 4.1(h)(ii)) continue to represent in the aggregate at least [***] Percent ([***] %) of COMPANY’s issued and outstanding Common Stock calculated on a FULLY DILUTED BASIS, as calculated after giving effect to the anti-dilutive issuance. Such issuances shall continue until and including the date upon which a total of [***] in cash in exchange for COMPANY’s capital stock (the “FUNDING THRESHOLD”) shall be received by COMPANY (and, for the avoidance of doubt, on such date only with respect to such [***] of fundraising and not with respect to amounts in excess of such threshold). Thereafter, no additional shares shall be due to the SHAREHOLDERS pursuant to this Section 4.1(h)(ii).

(iii) Participation in Private Equity Offerings After Funding Threshold. After the date of the Funding Threshold, M.I.T. shall have the right to purchase additional shares of COMPANY’s capital stock in exchange for cash in any private offering by COMPANY of such capital stock in exchange for cash, to maintain its pro rata ownership as calculated immediately prior to such offering on a FULLY DILUTED BASIS, to the extent any preferred stockholders have such rights in any such private offering (the “PARTICIPATION RIGHTS”). In connection with being granted the PARTICIPATION RIGHTS, M.I.T. shall become a party to any agreement requested by COMPANY that is between COMPANY and preferred stockholders of COMPANY and that contains a right to participate in any such private offering solely for the

purpose of such PARTICIPATION RIGHTS on the same terms as such other stockholders in satisfaction of COMPANY’S obligation under this Section 4.1(h)(iii). All rights granted to M.I.T. pursuant to this Section 4.1(h)(iii) shall terminate immediately prior to a firm commitment underwritten public offering of COMPANY’s common stock resulting in gross proceeds to COMPANY of at least [***]. M.I.T. shall not transfer or assign the PARTICIPATION RIGHTS to a third party without the prior written consent of COMPANY, which consent may be withheld by COMPANY in its sole discretion. [***].

(iv) Anti-Dilution Protection After Funding Threshold. The provisions of Annex 4.1(h)(iv) (attached hereto as Appendix D) are incorporated herein by reference. All rights granted to the Shareholders pursuant to this Section 4.1(h)(iv) shall terminate immediately prior to a firm commitment underwritten public offering of COMPANY’s common stock resulting in gross proceeds to COMPANY of at least [***].

(v) Miscellaneous.

(A) The SHARES, and all other shares of Common Stock and other securities of COMPANY that may be issued to the Shareholders pursuant to this Section 4.1(h), shall be duly authorized, validly issued, fully paid and nonassessable.

(B) COMPANY acknowledges that certain written policies of BCH, Harvard Medical School and affiliated organizations existing as of the EFFECTIVE DATE, relating to, inter alia, conflicts of interest and intellectual property, may cover certain direct and indirect arrangements between inventors and COMPANY or related organizations. BCH has provided COMPANY with copies of the relevant policies prior to the EFFECTIVE DATE. During the TERM, COMPANY shall notify BCH in writing at least [***] calendar days before COMPANY or any AFFILIATE enters into any agreement (other than this Agreement) that is covered by such written policies with or involving the inventor(s) of the invention covered by the PATENT RIGHTS licensed hereunder that are employees of BCH, or their family, relatives or members or staff of their laboratories, whether relating to sponsored research, consulting, board membership, securities, or otherwise. COMPANY’s notice to BCH shall include a reasonably detailed description of the material proposed terms and conditions. COMPANY shall not enter into such an agreement if it would violate such policies unless the terms and conditions of the agreement have been duly approved pursuant to such policies.

(i) No Multiple Royalties. If the manufacture, use, lease or sale of any LICENSED PRODUCT or the performance of any LICENSED PROCESS is covered by more than one of the PATENT RIGHTS, multiple royalties shall not be due. In addition, if any

product, process or service under this Agreement constitutes both a LICENSED PRODUCT and a LICENSED PROCESS, multiple royalties shall not be due.

4.2 Payments.

(a) Method of Payment. All payments under this Agreement should be made payable to “Massachusetts Institute of Technology” and sent to the address identified in Section 15.1. Each payment should reference this Agreement and identify the obligation under this Agreement that the payment satisfies. Unless otherwise stated on the invoice, payments sent by wire transfer shall be paid to:

Account Holder: MIT

[***]

(b) Payments in U.S. Dollars. All payments due under this Agreement shall be drawn on a United States bank and shall be payable in United States dollars. Conversion of foreign currency to U.S. dollars shall be made at the conversion rate existing in the United States (as reported by the Federal Reserve Bank of St. Louis) on the last working day of the calendar quarter of the applicable REPORTING PERIOD. Such payments shall be without deduction of exchange, collection, or other charges, and, specifically, without deduction of withholding or similar taxes or other government imposed fees or taxes, except as permitted in the definition of NET SALES.

(c) Late Payments. Any payments by COMPANY that are not paid on or before the date such payments are due under this Agreement shall bear interest, to the extent permitted by law, at [***] above the Prime Rate of interest as reported by the Federal Reserve Bank of St. Louis on the last business day of the calendar quarterly reporting period to which such royalty payments relate.

5. REPORTS AND RECORDS.

5.1 Reports.

(a) Progress Reports. COMPANY shall deliver progress reports to M.I.T. annually, within [***] days of the end of each calendar year, containing information concerning the immediately preceding calendar year, specifically including the following information:

6. PATENT PROSECUTION.

6.1 Responsibility for PATENT RIGHTS. M.I.T. shall prepare, file, prosecute, and maintain all of the PATENT RIGHTS. COMPANY shall have reasonable opportunities to advise M.I.T. and shall cooperate with M.I.T. in such filing, prosecution and maintenance.

In the event that COMPANY desires to discontinue its support of any patent or patent application within the PATENT RIGHTS in any particular country or countries, COMPANY shall provide M.I.T. with at least [***] days prior written notice of such intended discontinuance of support. In such event, on a country-by-country basis, (i) any such patent or patent application (the “RETURNED RIGHTS”) shall be removed from the definition of PATENT RIGHTS under this Agreement, (ii) the licenses granted to COMPANY and its AFFILIATES as to such RETURNED RIGHTS shall terminate, (iii) COMPANY shall have no further obligation with respect to such RETURNED RIGHTS pursuant to Section 6.3, and (iv) M.I.T. shall have the unrestricted right to license such RETURNED RIGHTS to third parties.

country-by-country basis, as an alternative to terminating the licenses granted to COMPANY and its AFFILIATES to such RETURNED RIGHTS as set forth in clause (ii) above, (I) to terminate the exclusivity of the license with respect to such RETURNED RIGHTS in the applicable country and (II) to continue to prosecute and maintain the RETURNED RIGHTS at its own expense. If M.I.T. makes such election, COMPANY and its AFFILIATES (A) shall retain a non-exclusive license under the RETURNED RIGHTS in the applicable country, and (B) will be obligated to pay a royalty on NET SALES of LICENSED PRODUCTS and LICENSED PROCESSES at a rate that is [***] percent ([***]%) of the rates set forth in Section 4.1(d) in the countries where it has non-exclusive rights, and M.I.T. shall have the unrestricted right to grant to third parties non-exclusive licenses under the RETURNED RIGHTS in such countries.

6.2 International (non-United States) Filings. Appendix B is a list of countries in which patent applications corresponding to the United States patent applications listed in Appendix A shall be filed, prosecuted, and maintained. Appendix B may be amended by mutual agreement of COMPANY and M.I.T.

7.2 Right to Prosecute Infringements.

(a) COMPANY Right to Prosecute. So long as COMPANY remains the exclusive licensee of the PATENT RIGHTS in any subset of the FIELD in the TERRITORY, COMPANY, to the extent permitted by law, shall have the first right, under its own control and at its own expense, to prosecute any third party infringement of the PATENT RIGHTS in such

subset of the FIELD in the TERRITORY, subject to Sections 7.4 and 7.5. If required by law, M.I.T. and BCH, as applicable, shall permit any action under this Section 7.2(a) to be brought in its name, including being joined as a party-plaintiff, provided that COMPANY shall hold M.I.T. and BCH, as applicable, harmless from, and indemnify M.I.T. and BCH, as applicable, against, any costs, expenses, or liability that M.I.T. and/or BCH, as applicable, incurs in connection with such action.

Prior to commencing any such action, COMPANY shall consult with M.I.T. and shall consider the views of M.I.T. regarding the advisability of the proposed action and its effect on other licensees of the PATENT RIGHTS and on the public interest. COMPANY shall not enter into any settlement, consent judgment, or other voluntary final disposition of any infringement action under this Section 7.2(a) without the prior written consent of M.I.T. (subject to concurrence of BCH, as applicable). COMPANY’s selection of counsel (to represent COMPANY and M.I.T. in such an action) shall be subject to M.I.T.’s approval, which shall not be unreasonably withheld, conditioned or delayed.

(b) M.I.T. Right to Prosecute. In the event that COMPANY is unsuccessful in persuading the alleged infringer to desist or fails to have initiated an infringement action within [***] days after COMPANY first becomes aware of the basis for such action, M.I.T. shall have the right, at its sole discretion, to prosecute such infringement under its sole control and at its sole expense, and any recovery obtained shall belong to M.I.T. M.I.T. shall consult with COMPANY prior to commencing any such action.

7.3 Third Party Patent Challenges. In the event that a PATENT CHALLENGE is brought by a third party, the parties shall promptly consult and determine a mutually acceptable strategy for the defense of such action at COMPANY’s expense using attorneys mutually acceptable to the parties.

7.4 Offsets. COMPANY may offset a total of [***] percent ([***]%) of any expenses incurred under Sections 7.2 and 7.3 against any payments due to M.I.T. under Article 4, provided that in no event shall such payments under Article 4, when aggregated with any other offsets and credits allowed under this Agreement, be reduced by more than [***] percent ([***]%) in any REPORTING PERIOD.

7.5 Recovery. Any recovery obtained in an action brought by COMPANY under Sections 7.2 or 7.3 shall be distributed as follows: (i) each party shall be reimbursed for any expenses incurred in the action (including the amount of any royalty or other payments withheld from M.I.T. as described in Section 7.4), (ii) as to ordinary damages, COMPANY shall receive an amount equal to its lost profits or a reasonable royalty on the infringing sales, or whichever measure of damages the court shall have applied, and COMPANY shall pay to M.I.T. based upon such amount a reasonable approximation of the royalties and other amounts that COMPANY would have paid to M.I.T. if COMPANY had sold the infringing products, processes and services rather than the infringer, and (iii) as to special or punitive damages, any award shall be shared [***] percent ([***]%) to M.I.T. and [***] percent ([***]%) to COMPANY.

7.6 Cooperation. Each party agrees to cooperate in any action under this Article which is controlled by the other party, provided that the controlling party reimburses the cooperating party promptly for any costs and expenses incurred by the cooperating party in connection with providing such assistance.

7.7 Right to Sublicense. So long as COMPANY remains the exclusive licensee of the PATENT RIGHTS in the FIELD in the TERRITORY, COMPANY shall have the sole right to sublicense any alleged infringer in the FIELD in the TERRITORY for future use of the PATENT RIGHTS in accordance with the terms and conditions of this Agreement relating to sublicenses. Any upfront fees as part of such sublicense shall be shared equally between COMPANY and M.I.T.; other revenues to COMPANY pursuant to such sublicense shall be treated as set forth in Article 4.

any product, process, or service that is made, used, sold, imported, or performed pursuant to any right or license granted under this Agreement, or (ii) arising out of or related to the exercise of any rights granted to COMPANY under this Agreement or any breach of this Agreement by COMPANY.

(b) Procedures. The INDEMNITEES agree to provide COMPANY with prompt written notice of any claim, suit, action, demand, or judgment for which indemnification is sought under this Agreement. COMPANY agrees, at its own expense, to provide attorneys reasonably acceptable to M.I.T. to defend against any such claim. The INDEMNITEES shall cooperate fully with COMPANY in such defense and will permit COMPANY to conduct and control such defense and the disposition of such claim, suit, or action (including all decisions relative to litigation, appeal, and settlement); provided, however, that any INDEMNITEE shall have the right to retain its own counsel, at the expense of COMPANY, if representation of such INDEMNITEE by the counsel retained by COMPANY would be inappropriate because of actual or potential differences in the interests of such INDEMNITEE and any other party represented by such counsel. COMPANY agrees to keep M.I.T. and BCH (as applicable) informed of the progress in the defense and disposition of such claim and to consult with M.I.T. and BCH (as applicable) with regard to any proposed settlement.

Notwithstanding anything to the contrary in this Agreement, COMPANY shall not enter into any settlement, consent judgment, or other voluntary final disposition of any claim that has a material adverse effect on the rights of any INDEMNITEE(S) hereunder or admits any wrongdoing or fault by any INDEMNITEE(S) or imposes on any INDEMNITEE(S) any payment or other liability, without the prior written consent of such INDEMNITEE(S).

COMPANY shall obtain and carry in full force and effect commercial general liability insurance, including products/completed operations coverage (subject to clause (iii) below) and errors and omissions liability insurance which shall protect COMPANY and INDEMNITEES with respect to events covered by Section 8.1(a) above. Such insurance (i) shall be issued by an insurer licensed to practice in the United States and will be provided by a company or companies having a financial rating of not less than A- Viii in the most current edition of Best’s Key Rating Guide, or an insurer pre-approved by M.I.T., such approval not to be unreasonably withheld, conditioned or delayed and (ii) shall list M.I.T. and BCH as additional insureds thereunder, for the commercial general liability policy only, and, if issued as a separate policy, product liability policy (iii) shall include product liability coverage at least [***] days prior to the earlier of (1) the initiation of a clinical trial with respect to any LICENSED PRODUCT or LICENSED PROCESS or (2) commercial distribution, sale, lease, transfer or

performance or use of any LICENSED PRODUCT or LICENSED PROCESS by COMPANY, or any AFFILIATE or SUBLICENSEE, and (iv) shall require [***] days written notice to be given to M.I.T. prior to any cancellation or material change thereof. The limits of the commercial general liability insurance shall not be less than [***] per occurrence with an annual aggregate of [***] for bodily injury including death, property damage, and products/completed operations coverage. The limits of the errors and omissions liability insurance shall not be less than [***] per claim and in the aggregate. COMPANY shall continue to maintain such insurance after the expiration or termination of this Agreement during any period in which COMPANY or any AFFILIATE or SUBLICENSEE continues (i) to make, use, or sell a product that was a LICENSED PRODUCT under this Agreement or (ii) to perform a service that was a LICENSED PROCESS under this Agreement, and thereafter for a period of [***] years, if the coverage is under a claims-made policy.

If COMPANY desires to self-insure all or part of the limits described above (including deductibles or retentions which are in excess of [***] annual aggregate), such self-insurance program must be acceptable to M.I.T., BCH and the Risk Management Foundation of the Harvard Medical Institutions, Inc. The minimum amounts of insurance coverage required under this Section 8.2 shall not be construed to create a limit of COMPANY’s liability with respect to its indemnification under Section 8.1 of this Agreement. If there is a cancellation, non-renewal, or material change in insurance, and COMPANY does not obtain replacement insurance providing comparable coverage prior to the expiration of the [***] day notice period described above, M.I.T. shall have the right to terminate this Agreement effective at the end of such [***] day period without notice or any additional waiting periods.

Anti-Dilution Protection After Funding Threshold

1. Adjustments for Certain Dilutive Issuances.

(a) Definitions. For purposes of this Section 1, the following definitions shall apply:

(i) “Additional Shares of Common Stock” shall mean all shares of Common Stock issued (or, pursuant to Section 1(b) below, deemed to be issued) by the COMPANY after the Threshold Date, other than (1) the following shares of Common Stock and (2) shares of Common Stock deemed issued pursuant to the following Options and Convertible Securities (clauses (1) and (2), collectively, “Exempted Securities”):

(A) shares of Common Stock issued pursuant to the terms of this Section 1;

(B) shares of Common Stock, Options or Convertible Securities issued by reason of a dividend, stock split, split-up or other distribution on all then outstanding shares of Common Stock;

(C) shares of Common Stock or Convertible Securities actually issued upon the exercise of Options or shares of Common Stock actually issued upon the conversion or exchange of Convertible Securities, in each case provided such issuance is pursuant to the terms of such Option or Convertible Security;

(D) shares of Common Stock, Options or Convertible Securities issued as a dividend or distribution on any series of Preferred Stock of the COMPANY;

(E) shares of Common Stock or Options issued to employees or directors of, or consultants or advisors to, the COMPANY or any of its subsidiaries pursuant to a plan, agreement or arrangement approved by the Board of Directors of the COMPANY;

(F) shares of Common Stock, Options or Convertible Securities issued to banks, equipment lessors or other financial institutions, or to real property lessors, pursuant to a debt financing, equipment leasing or real property leasing transaction approved by the Board of Directors of the COMPANY;

(G) shares of Common Stock, Options or Convertible Securities issued to suppliers or third party service providers as consideration for the provision of goods or services pursuant to transactions approved by the Board of Directors of the COMPANY;

(H) shares of Common Stock, Options or Convertible Securities issued as consideration for the acquisition of another corporation by the COMPANY by merger, purchase of substantially all of the assets or other reorganization or to a joint venture agreement, provided that such issuances are approved by the Board of Directors of the COMPANY; or

(I) shares of Common Stock, Options or Convertible Securities issued as consideration in connection with sponsored research, collaboration, technology license,

development, marketing or other similar agreements or strategic partnerships approved by the Board of Directors of the COMPANY.

(ii) “Convertible Securities” shall mean any evidences of indebtedness, shares or other securities directly or indirectly convertible into or exchangeable for Common Stock, but excluding Options.

(iii) “Options” shall mean rights, options or warrants to subscribe for, purchase or otherwise acquire Common Stock or Convertible Securities.

(iv) “Share Price” shall mean the Threshold Share Price, subject to adjustment following the Threshold Date as provided in this Section 1.

(v) “Threshold Date” shall mean the date of the Funding Threshold.

(vi) “Threshold Share Price” shall mean the fair market value per share of the Common Stock as of the Threshold Date, as determined in good faith by the Board of Directors of the COMPANY by the reasonable application of a reasonable valuation method in accordance with the provisions of Treasury Regulation § 1.409A-1(b)(iv)(B), subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Common Stock occurring after the Threshold Date. On or as soon as reasonably practicable following the Threshold Date, the COMPANY shall give written notice to each Shareholder of the Threshold Share Price as determined in accordance with the foregoing, together with reasonable supporting details. Upon the reasonable request of a Shareholder, the COMPANY shall afford such Shareholder a reasonable opportunity to consult with management of the COMPANY in connection with the determination of the Threshold Share Price, whether prior to or after such determination has been made.

(vii) “Threshold Shares” shall mean, with respect to each Shareholder, the number of shares of Common Stock held by such Shareholder as of the Threshold Date, subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Common Stock occurring after the Threshold Date.

(b) Deemed Issue of Additional Shares of Common Stock.

(i) If the COMPANY at any time or from time to time after the Threshold Date shall issue any Options or Convertible Securities (excluding Options or Convertible Securities which are themselves Exempted Securities) or shall fix a record date for the determination of holders of any class of securities entitled to receive any such Options or Convertible Securities, then the maximum number of shares of Common Stock (as set forth in the instrument relating thereto, assuming the satisfaction of any conditions to exercisability, convertibility or exchangeability but without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Shares of Common Stock issued as of the time of such issue or, in case such a record date shall have been fixed, as of the close of business on such record date.

(ii) If the terms of any Option or Convertible Security, the issuance of which resulted in an adjustment to the Share Price pursuant to the terms of Section 1(c) below are revised

as a result of an amendment to such terms or any other adjustment pursuant to the provisions of such Option or Convertible Security to provide for either (1) any increase or decrease in the number of shares of Common Stock issuable upon the exercise, conversion and/or exchange of any such Option or Convertible Security or (2) any increase or decrease in the consideration payable to the COMPANY upon such exercise, conversion or exchange, then, effective upon such increase or decrease becoming effective, the Share Price computed upon the original issue of such Option or Convertible Security (or upon the occurrence of a record date with respect thereto) shall be readjusted to such Share Price as would have obtained had such revised terms been in effect upon the original date of issuance of such Option or Convertible Security. Notwithstanding the foregoing, no readjustment pursuant to this clause (ii) shall have the effect of increasing the Share Price to an amount which exceeds the lower of (A) the Share Price in effect immediately prior to the original adjustment made as a result of the issuance of such Option or Convertible Security, or (B) the Share Price that would have resulted from any issuances of Additional Shares of Common Stock (other than deemed issuances of Additional Shares of Common Stock as a result of the issuance of such Option or Convertible Security) between the original adjustment date and such readjustment date.

(iii) If the terms of any Option or Convertible Security (excluding Options or Convertible Securities which are themselves Exempted Securities), the issuance of which did not result in an adjustment to the Share Price pursuant to the terms of Section 1(c) (either because the consideration per share (determined pursuant to Section 1(e)) of the Additional Shares of Common Stock subject thereto was equal to or greater than the Share Price then in effect, or because such Option or Convertible Security was issued on or before the Threshold Date), are revised after the Threshold Date as a result of an amendment to such terms or any other adjustment pursuant to the provisions of such Option or Convertible Security to provide for either (1) any increase in the number of shares of Common Stock issuable upon the exercise, conversion or exchange of any such Option or Convertible Security or (2) any decrease in the consideration payable to the COMPANY upon such exercise, conversion or exchange, then such Option or Convertible Security, as so amended or adjusted, and the Additional Shares of Common Stock subject thereto (determined in the manner provided in Section 1(b)(i)) shall be deemed to have been issued effective upon such increase or decrease becoming effective.

(iv) Upon the expiration or termination of any unexercised Option or unconverted or unexchanged Convertible Security (or portion thereof) which resulted (either upon its original issuance or upon a revision of its terms) in an adjustment to the Share Price pursuant to the terms of Section 1(c), the Share Price shall be readjusted to such Share Price as would have obtained had such Option or Convertible Security (or portion thereof) never been issued.

(v) If the number of shares of Common Stock issuable upon the exercise, conversion and/or exchange of any Option or Convertible Security, or the consideration payable to the COMPANY upon such exercise, conversion and/or exchange, is calculable at the time such Option or Convertible Security is issued or amended but is subject to adjustment based upon subsequent events, any adjustment to the Share Price provided for in this Section 1(b) shall be effected at the time of such issuance or amendment based on such number of shares or amount of consideration without regard to any provisions for subsequent adjustments (and any subsequent adjustments shall be treated as provided in clauses (ii) and (iii) of this Section 1(b)). If the number of shares of Common Stock issuable upon the exercise, conversion and/or exchange of any Option or Convertible Security, or the consideration payable to the COMPANY upon such exercise,

conversion and/or exchange, cannot be calculated at all at the time such Option or Convertible Security is issued or amended, any adjustment to the Share Price that would result under the terms of this Section 1(b) at the time of such issuance or amendment shall instead be effected at the time such number of shares and/or amount of consideration is first calculable (even if subject to subsequent adjustments), assuming for purposes of calculating such adjustment to the Share Price that such issuance or amendment took place at the time such calculation can first be made.

(c) Adjustment of Share Price Upon Issuance of Additional Shares of Common Stock. In the event the COMPANY shall at any time after the Threshold Date issue Additional Shares of Common Stock (including Additional Shares of Common Stock deemed to be issued pursuant to Section 1(b)), without consideration or for a consideration per share less than the Share Price in effect immediately prior to such issue, then the Share Price shall be reduced, concurrently with such issue of Additional Shares of Common Stock, to a price (calculated to the nearest one-hundredth of a cent) determined in accordance with the following formula:

P2 = P1 * (A + B) ÷ (A + C).

For purposes of the foregoing formula, the following definitions shall apply:

(i) “P2” shall mean the Share Price in effect immediately after such issue of Additional Shares of Common Stock;

(ii) “P1” shall mean the Share Price in effect immediately prior to such issue of Additional Shares of Common Stock;

(iii) “A” shall mean the number of shares of Common Stock outstanding immediately prior to such issue of Additional Shares of Common Stock (treating for this purpose as outstanding all shares of Common Stock issuable upon exercise of Options outstanding immediately prior to such issue or upon conversion or exchange of Convertible Securities outstanding (assuming exercise of any outstanding Options therefor) immediately prior to such issue);

(iv) “B” shall mean the number of shares of Common Stock that would have been issued if such Additional Shares of Common Stock had been issued at a price per share equal to P1 (determined by dividing the aggregate consideration received by the COMPANY in respect of such issue by P1); and

(v) “C” shall mean the number of such Additional Shares of Common Stock issued in such transaction.

(d) Issuance of Anti-Dilution Shares Upon Adjustment of Share Price. In the event of any adjustment of the Share Price pursuant to this Section 1, then the COMPANY shall issue to each Shareholder, concurrently with such adjustment of the Share Price, a number of shares of Common Stock, rounded up to the nearest whole number of shares (any such shares issued pursuant to this Section 1(d), “Anti-Dilution Shares”) determined in accordance with the following formula (it being understood, for avoidance of doubt, that no such issuance shall be required unless the following formula results in a positive number):

S3 = S1 * (TSP ÷ SP) — S1 — S2.

For purposes of the foregoing formula, the following definitions shall apply:

(i) “S3” shall mean the number of new Anti-Dilution Shares to be issued to such Shareholder;

(ii) “S1” shall mean the Threshold Shares of such Shareholder;

(iii) “S2” shall mean the aggregate number of Anti-Dilution Shares, if any, issued to such Shareholder as determined immediately prior to such issue of new Anti-Dilution Shares (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Common Stock);

(iv) “TSP” shall mean the Threshold Share Price; and

(v) “SP” shall mean the Share Price then in effect (after giving effect to the adjustment thereto giving rise to this calculation under Section 1(d)).

(e) Determination of Consideration. For purposes of this Section 1, the consideration received by the COMPANY for the issue of any Additional Shares of Common Stock shall be computed as follows:

(i) Cash and Property: Such consideration shall:

(A) insofar as it consists of cash, be computed at the aggregate amount of cash received by the COMPANY, excluding amounts paid or payable for accrued interest;

(B) insofar as it consists of property other than cash, be computed at the fair market value thereof at the time of such issue, as determined in good faith by the Board of Directors of the COMPANY; and

(C) in the event Additional Shares of Common Stock are issued together with other shares or securities or other assets of the COMPANY for consideration which covers both, be the proportion of such consideration so received, computed as provided in (A) and (B) above, as determined in good faith by the Board of Directors of the COMPANY.

(ii) Options and Convertible Securities. The consideration per share received by the COMPANY for Additional Shares of Common Stock deemed to have been issued pursuant to Section 1(b), relating to Options and Convertible Securities, shall be determined by dividing:

(A) the total amount, if any, received or receivable by the COMPANY as consideration for the issue of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the COMPANY upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities, by

(B) the maximum number of shares of Common Stock (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities.

(f) Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Share Price pursuant to this Section 1, the COMPANY at its expense shall, as promptly as reasonably practicable, compute such adjustment or readjustment in accordance with the terms hereof and furnish to each Shareholder a certificate setting forth (i) such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based and (ii) the number of Anti-Dilution Shares issued or to be issued to such Shareholder as a result of such adjustment or readjustment. The COMPANY shall, as promptly as reasonably practicable after the written request at any time of any Shareholder, furnish or cause to be furnished to such holder a certificate setting forth the Share Price and the Threshold Share Price then in effect.
