WHEREAS, COMPANY desires to obtain a license under the PATENT RIGHTS upon the terms and conditions hereinafter set forth.

NOW, THEREFORE, M.I.T. and COMPANY hereby agree as follows:

1. DEFINITIONS.

1.1 “AFFILIATE” shall mean any legal entity (including, but not limited to, a corporation, partnership, or limited liability company) that is controlled by COMPANY. For the purposes of this definition, the term “control” means (i) beneficial ownership of at least fifty percent (50%) of the voting securities of a corporation or other business organization with voting securities or (ii) a fifty percent (50%) or greater interest in the net assets or profits of a partnership or other business organization without voting securities.

1.2 “COLLABORATION INVENTION” shall mean any patentable invention that is jointly owned between the parties and which is:

(i) arising from collaborative research solely between the laboratory of ▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇▇ at M.I.T. and COMPANY, as reflected by both (a) ▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇▇ and (b) at least one employee of COMPANY being inventors of such invention, and directed to anti-dengue virus antibodies targeting the “A” b-strand of E protein domain III (EDIII) of the dengue virus; and

(ii) disclosed to the M.I.T. Technology Licensing Office and conceived and reduced to practice within [**] years of the EFFECTIVE DATE; and

(iii) dominated by claims of the PATENT RIGHTS licensed under this Agreement and listed in Appendix A as of the EFFECTIVE DATE; and

(iv) available for licensing after satisfaction of any obligations to third parties, including without limitation sponsors of the research leading to such invention.

For clarity, any invention that includes ownership rights of a third party or which includes inventors from laboratories at M.I.T. other than that of ▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇▇ shall not be considered a COLLABORATION INVENTION hereunder.

1.3 “CONFIDENTIAL INFORMATION” shall mean any confidential or proprietary information furnished by COMPANY (the “Disclosing Party”) to M.I.T. (the “Receiving Party”) in connection with this Agreement, provided that such information is specifically designated as confidential in accordance with Article 14. Such CONFIDENTIAL INFORMATION shall include, without limitation, any diligence reports furnished to M.I.T. under Section 3.1, royalty reports furnished to M.I.T. under Section 5.2, and copies of sublicenses furnished to M.I.T. under Section 2.3, provided that such information is designated as confidential.

1.4 “DEVELOPING COUNTRY(IES)” shall mean any countries that are currently eligible for support from the GAVI Alliance and identified at ▇▇▇▇://▇▇▇.▇▇▇▇▇▇▇▇▇▇▇▇.▇▇▇/▇▇▇▇▇▇▇/▇▇▇▇▇/▇▇▇▇▇▇▇▇▇-▇▇▇▇▇▇▇▇-▇▇▇-▇▇▇▇▇▇▇/, as such list may change from time to time, or any subsequent list that may be mutually agreed upon by M.I.T. and COMPANY.

1.5 “EXCLUSIVE PERIOD” shall mean the period of time set forth in Section 2.2.

1.6 “FIELD” shall mean treatment and/or prophylaxis of disease in humans.

1.7 “LICENSED PRODUCT” shall mean any product that, in whole or in part:

(i) absent the license granted hereunder, would infringe one or more claims of the PATENT RIGHTS; or

(ii) is manufactured by using a LICENSED PROCESS or that, when used, practices a LICENSED PROCESS.

In recognition of the value of the PATENT RIGHTS for M.I.T. Case No. [**] in identifying and/or designing related products, M.I.T. and COMPANY agree that any product that is identified, derived and/or designed by COMPANY or an AFFILIATE or SUBLICENSEE, in whole or in part, through the use of novel sequences, including without limitation variable heavy and variable light domain sequences, or a fragment thereof (e.g., a CDR sequence), disclosed in M.I.T. Case No. [**] (including without limitation, a molecule that comprises a derivative of a novel variable heavy and variable light domain sequence, or fragment thereof, described therein) shall be deemed a LICENSED PRODUCT for the purposes of this Agreement.

1.8 “LICENSED PROCESS” shall mean any process that, absent the license granted hereunder, would infringe one or more claims of the PATENT RIGHT’S or which uses a LICENSED PRODUCT.

1.9 “NET SALES” shall mean the gross amount billed by COMPANY and its AFFILIATES and SUBLICENSEES for LICENSED PRODUCTS and LICENSED PROCESSES, less the following:

(i) customary trade, quantity, or cash discounts to the extent actually allowed and taken;

(ii) amounts repaid or credited by reason of rejection or return:

(iii) to the extent separately stated on purchase orders, invoices, or other documents of sale, any taxes or other governmental charges levied on the production, sale,

transportation, delivery, or use of a LICENSED PRODUCT or LICENSED PROCESS which is paid by or on behalf of COMPANY; and

(iv) outbound transportation costs prepaid or allowed and costs of insurance in transit.

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 earlier of the receipt of payment or ninety (90) days after the date of billing for a LICENSED PRODUCT or LICENSED PROCESS. If a LICENSED PRODUCT or a LICENSED PROCESS is distributed at a discounted price that is substantially lower than the customary price charged by COMPANY (taking into account customary pricing for a governmental entity), or distributed for non-cash 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 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.

Non-monetary consideration shall not be accepted by COMPANY, any AFFILIATE, or any SUBLICENSEE for any LICENSED PRODUCTS or LICENSED PROCESSES without the prior written consent of M.I.T. In the event that non-monetary consideration is received for LICENSED PRODUCTS or LICENSED PROCESSES, NET SALES shall be calculated based on the fair market value of such non-monetary consideration, including all elements of such consideration, as determined by the parties in good faith.

NET SALES will be calculated only once with respect to each LICENSED PRODUCT or 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, NET SALES will not include transfers among COMPANY and any AFFILIATE and/or SUBLICENSEE unless the recipient does not intend to further sell or transfer the LICENSED PRODUCT or LICENSED PROCESS and is the end user thereof.

1.10 “OTHER COUNTRY(IES)” shall mean any country in the TERRITORY other than DEVELOPING COUNTRIES.

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

1.12 “PATENT RIGHTS” shall mean:

(a) the United States and international patents listed on Appendix A;

(b) the United States and international patent applications and/or provisional applications listed on Appendix A and the resulting patents;

(c) any patent applications resulting from the provisional applications listed on Appendix A, and any divisional, continuations, continuation-in-part applications, and continued prosecution applications (and their relevant international equivalents) of the patent applications listed on Appendix A and of such patent applications that result from the provisional applications listed on Appendix A, to the extent the claims are directed to subject matter specifically described in the patent applications listed on Appendix A, and the resulting patents;

(d) any patents resulting from reissues, reexaminations, or extensions (and their relevant international equivalents) of the patents described in (a), (b), and (c) above; and

(e) international (non-United States) patent applications and provisional applications filed after the EFFECTIVE DATE and the relevant international equivalents to divisionals, continuations, continuation-in-part applications and continued prosecution applications of the patent applications to the extent the claims are directed to subject matter specifically described in the patents or patent applications referred to in (a), (b), (c), and (d) above, and the resulting patents.

1.13 “REPORTING PERIOD” shall begin on the first day of each calendar quarter and end on the last day of such calendar quarter.

1.14 “RESEARCH SUPPORT PAYMENTS” shall mean payments to COMPANY from a SUBLICENSEE for the purposes of funding the costs of bona fide research and development activities with respect to LICENSED PRODUCTS and/or LICENSED PROCESSES covered by rights granted in the sublicense agreement to such SUBLICENSEE, and only to the extent that COMPANY can demonstrate that (i) such costs are incurred after the date of such sublicense agreement pursuant to a written research and development plan and budget, both as mutually agreed between COMPANY and such SUBLICENSEE, and (ii) such payments are only used to pay for: (a) the purchase, lease or use of equipment, supplies, raw materials, products or services, or (b) the use of employees and/or consultants, to achieve a bona fide research and/or development goal for the commercialization of such LICENSED PRODUCTS or LICENSED PROCESSES, as indicated by their inclusion as specific line items in the research and development plan.

1.15 “SUBLICENSE INCOME” shall mean any payments that COMPANY receives from a SUBLICENSEE in consideration of the sublicense of the rights granted COMPANY under Section 2.1, including without limitation license fees, milestone payments (net of any amount due to M.I.T. under Section 4.1(c) for a substantially identical milestone event), license maintenance fees, and other payments, but specifically excluding (i) royalties on NET SALES or payments as a sharing of profits from NET SALES of LICENSED PRODUCTS or LICENSED PROCESSES, (ii) RESEARCH SUPPORT PAYMENTS, (iii) reimbursement of out-of-pocket patent prosecution and defense expenses for PATENT RIGHTS, and (iv) payments made as consideration for the issuance of equity or debt securities of COMPANY at fair market value (excluding amounts in excess of the fair market value of such securities). As used herein a “substantially identical” milestone event shall mean the achievement of a functionally equivalent developmental goal for a LICENSED PRODUCT; for example, the commencement of a Phase 2 clinical trial is a substantially identical milestone event as completion of a Phase 1 clinical trial, as both are in recognition of a LICENSED PRODUCT having completed Phase 1 trials and entering into Phase 2 trials. In addition, with respect to “payments as a sharing of profits from NET SALES”, “profits” shall mean NET SALES less selling expenses and manufacturing costs of the product, and such payments shall not include milestone and/or bonus payments related to sales of LICENSED PRODUCTS or LICENSED PROCESSES.

Consideration for any and all sublicenses of the PATENT RIGHTS shall be on commercially reasonable terms and conditions. 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.

1.16 “SUBLICENSEE” shall mean any non-AFFILIATE sublicensee of the rights granted COMPANY tinder Section 2.1. For clarity, a sublicense shall include (i) any right granted, license given or agreement entered into by COMPANY to or with another person or entity, under or with respect to or permitting any use of the PATENT RIGHTS or otherwise granting rights to such person or entity under the rights granted COMPANY under Section 2.1, (ii) any option or other right granted by COMPANY to any other person or entity to negotiate for or receive any of the rights described under clause (i), or (iii) any standstill or similar obligation undertaken by COMPANY toward another person or entity not to grant any of the rights described in clause (i) or (ii) to any third party, in each case regardless of whether such grant of rights, license given or agreement entered into is referred to or is described as a sublicense.

1.17 “TERM” shall mean the term of this Agreement, which shall commence on the EFFECTIVE DATE and shall remain in effect until the expiration or abandonment of all issued patents and filed patent applications within the PATENT RIGHTS, unless earlier terminated in accordance with the provisions of this Agreement.

1.18 “TERRITORY” shall mean worldwide.

2. GRANT OF RIGHTS.

2.1 License Grants. Subject to the terms of this Agreement, M.I.T. hereby grants to COMPANY and its AFFILIATES for the TERM a royalty-bearing license under the PATENT RIGHTS to develop, make, have made, use, sell, offer to sell, lease, and import LICENSED PRODUCTS in the FIELD in the TERRITORY and to develop and perform LICENSED PROCESSES in the FIELD in the TERRITORY,

2.2 Exclusivity.

(a) In order to establish an exclusive period for COMPANY, M.I.T. agrees that, subject to Sections 2.2(b) and 2.6, it shall not grant any other license under the PATENT RIGHTS to make, have made, use, sell, lease and import LICENSED PRODUCTS in the FIELD in the TERRITORY or to perform LICENSED PROCESSES in the FIELD in the TERRITORY during the TERM (the “EXCLUSIVE PERIOD”), unless sooner terminated as provided in this Agreement.

(b) If M.I.T. or COMPANY or an AFFILIATE receives a bona fide request from a capable third party for a license under the PATENT RIGHTS to develop and commercialize a LICENSED PRODUCT and/or LICENSED PROCESS at affordable prices in one or more DEVELOPING COUNTRIES that is not being sold (including without limitation sufficient supply to meet market demand at reasonable costs) or diligently developed for sale by COMPANY or an AFFILIATE or SUBLICENSEE in such DEVELOPING COUNTRY(IES), then the party receiving such inquiry shall promptly notify the other party in writing within [**] days of such inquiry (an “INQUIRY NOTICE”), setting forth the type of LICENSED PRODUCT and/or LICENSED PROCESS desired, the commercialization area desired, the name and contact information of the third party, and any other pertinent information.

Within [**] months of such INQUIRY NOTICE, during which time COMPANY may consult with M.I.T. regarding the request, COMPANY shall enter into a sublicense agreement containing commercially reasonable terms and conditions with such third

party for the requested LICENSED PRODUCT and/or LICENSED PROCESS in the requested DEVELOPING COUNTRY(IES). If COMPANY does not grant a sublicense under the PATENT RIGHTS to the third party within [**] months of such INQUIRY NOTICE, and M.I.T., at its sole discretion, determines that a sublicense to the third party is reasonable under the totality of the circumstances (taking into account development efforts of COMPANY, AFFILIATES and SUBLICENSEES) to make LICENSED PRODUCTS and/or LICENSED PROCESSES available in DEVELOPING COUNTRIES, then M.I.T. shall have the right to grant a non-exclusive license under the PATENT RIGHTS to such third party for such purposes and shall notify COMPANY of any such license that is granted. For clarity, any license granted by M.I.T. under this Section 2.2(b) shall be solely for bringing LICENSED PRODUCTS and/or LICENSED PROCESSES to market in the requested DEVELOPING COUNTRY(IES) (and other countries mutually agreed to by M.I.T. and COMPANY) in a manner that enables availability and accessibility at reasonable cost, and shall specifically exclude the right of the third party licensee to export or sell LICENSED PRODUCTS and/or LICENSED PROCESSES from such DEVELOPING COUNTRY(IES) (and other countries mutually agreed to by M.I.T. and COMPANY) into other markets. Notwithstanding the foregoing, any such license granted by M.I.T. under this Section 2.2(b) shall allow the third party licensee to export or sell LICENSED PRODUCTS and/or LICENSED PROCESSES from a DEVELOPING COUNTRY(IES) into any other DEVELOPING COUNTRY(IES) during any period of time in which an adequate supply of such LICENSED PRODUCTS and/or LICENSED PROCESSES at accessible pricing is not available in such other DEVELOPING COUNTRY(IES).

2.3 Limited Term Option to COLLABORATION INVENTIONS.

(a) To the extent that a COLLABORATION INVENTION is available for licensing, and subject to (i) any obligations of M.I.T. to third parties and (ii) the consent of M.I.T.’s Investigator ▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇▇, M.I.T. hereby grants to COMPANY a first option (the “Option”) to add M.I.T.’s interest in such COLLABORATION INVENTION to this Agreement, by amendment, in accordance with this Section 2.3.

(b) Promptly after the M.I.T. Technology Incensing Office receives disclosure of a COLLABORATION INVENTION, the M.I.T. Technology Licensing Office shall notify COMPANY in writing of the COLLABORATION INVENTION, furnishing COMPANY a copy of the invention disclosure and/or any related patent application(s). Such invention disclosure and any related patent application(s) shall be kept confidential by COMPANY. Notwithstanding the foregoing, M.I.T. shall be under no obligation to file patent applications for any

COLLABORATION INVENTION unless COMPANY exercises its Option with respect to such COLLABORATION INVENTION.

(c) COMPANY may exercise its Option to obtain a license to patent rights on such COLLABORATION INVENTION by notifying M.I.T. thereof in writing within [**] days after M.I.T.’s notice of such COLLABORATION INVENTION (the “Option Period”). If COMPANY does not exercise its Option within the Option Period, COMPANY’S rights under this Section 2.3 shall expire and M.I.T. shall be free to license such COLLABORATION INVENTION to any third party.

(d) For each Option so exercised, COMPANY will pay M.I.T. an Improvement Addition Fee of [**] dollars ($[**]), and shall be responsible for the payment of fees and costs relating to the filing, prosecution and maintenance of the patent rights covering such COLLABORATION INVENTION. Upon COMPANY’s exercise of such right and payment of the fee, the parties shall amend this Agreement to add the patent application(s) covering such COLLABORATION INVENTION under applicable terms and conditions.

2.4 Sublicenses. COMPANY shall have the right to grant sublicenses of its rights under Section 2.1 only during the EXCLUSIVE PERIOD, Such sublicenses may extend past the expiration date of the EXCLUSIVE PERIOD, but any exclusivity of such sublicense shall expire upon the expiration of the EXCLUSIVE PERIOD, COMPANY shall incorporate terms and conditions into its sublicense agreements sufficient to enable COMPANY to comply with this Agreement. COMPANY shall also include provisions in all sublicenses to provide that in the event that SUBLICENSEE brings a PATENT CHALLENGE against M.I.T. or assists another party in bringing a PATENT CHALLENGE against M.I.T. (except as required under a court order or subpoena) then COMPANY may terminate the sublicense, COMPANY shall promptly furnish M.I.T. with a fully signed photocopy of any sublicense agreement, which may be redacted to preserve any confidential information of the parties thereto (except that terms directly relevant to COMPANY’s and AFFILIATE’s obligations under this AGREEMENT may not be redacted). Upon termination of this Agreement for any reason, any SUBLICENSEE not then in default shall have the right to seek a license from M.I.T. M.I.T. agrees to negotiate such licenses in good faith under reasonable terms and conditions.

2.5 U.S. Manufacturing. COMPANY agrees that any LICENSED PRODUCTS used or sold in the United States will be manufactured substantially in the United States to the extent required by applicable laws and/or regulations.

2.6 Retained Rights.

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

(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.

2.7 No Additional Rights. 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.

(a) General Diligence Requirements. COMPANY shall use diligent efforts, or shall cause its AFFILIATES and SUBLICENSEES to use diligent 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 or SUBLICENSEES shall make LICENSED PRODUCTS or LICENSED PROCESSES reasonably available to the public. Specifically, COMPANY or an AFFILIATE or SUBLICENSEE shall fulfill the following obligations:

(i) Within six (6) 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 number of staff and other resources to be devoted to such commercialization effort.

(ii) Within sixty (60) 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 a discussion of intended efforts and sales projections for the year in which the report is submitted.

(iii) COMPANY shall expend (either directly or through AFFILIATES or SUBLICENSEES) at least the amounts set forth below on research toward the development of LICENSED PRODUCTS or LICENSED PROCESSES in each calendar year (pro-rated for partial years) beginning in 2013 and ending with the first commercial sale of a LICENSED PRODUCT.


2013		[**]

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(a), then M.I.T. may treat such failure as a material breach in accordance with Section 12.3(b).

Notwithstanding the foregoing, in the event that COMPANY anticipates a failure to meet an obligation set forth in in Sections 3.1(a)(iv), 3.1(a)(v) or 3.1(a)(vi) due to unexpected technical, adverse events or regulatory difficulties, COMPANY will promptly notify M.I.T. in writing, in advance of the relevant deadline, and representatives of each party will meet to review the reasons for the anticipated failure (taking into accounted delays beyond the reasonable control of COMPANY) and discuss in good faith a potential reasonable revision to the diligence schedule under this Section 3.1(a). 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; for clarification, M.I.T. shall have no obligation to agree to amend the diligence obligations hereunder. If the parties are unable to negotiate such an amendment within [**] days from the date of COMPANY’s notification pursuant to this Section, then M.I.T. may treat such failure as a material breach in accordance with Section 12.3(b).

(b) Diligence Requirements for DEVELOPING COUNTRIES. M.I.T. and COMPANY agree that it is an important objective of both parties that LICENSED PRODUCTS and LICENSED PROCESSES be made available in DEVELOPING COUNTRIES on reasonable terms, both with respect to availability of sufficient quantities of LICENSED PRODUCTS and LICENSED PROCESSES and the cost thereof. Specifically, COMPANY or AFFILIATE shall fulfill the following obligations:

(i) Within twelve (12) months after the EFFECTIVE DATE, COMPANY shall furnish M.I.T. with a written development and commercialization plan describing the COMPANY’s strategy for bringing LICENSED PRODUCTS and LICENSED PROCESSES to market in DEVELOPING COUNTRIES in a manner that is designed to enable availability and accessibility at reasonable cost, and shall discuss with M.I.T. the plan and provide an opportunity for M.I.T. to comment on the plan. COMPANY shall use diligent efforts to develop and commercialize LICENSED PRODUCTS and LICENSED PROCESSES in DEVELOPING COUNTRIES in accordance with such plan.

(ii) Within sixty (60) days alter the end of each calendar year, COMPANY shall furnish M.I.T. with a written report on the progress of its efforts during the immediately preceding calendar year to develop and commercialize LICENSED PRODUCTS and LICENSED PROCESSES in DEVELOPING COUNTRIES.

(iii) COMPANY shall use reasonable efforts to either (I) obtain the commitment of its SUBLICENSEES to use diligent efforts to develop and commercialize LICENSED PRODUCTS and LICENSED PROCESSES in DEVELOPING COUNTRIES

in a manner that is designed to enable availability and accessibility at reasonable cost, or (II) retain rights to develop and commercialize LICENSED PRODUCTS and LICENSED PROCESSES in DEVELOPING COUNTRIES.

(iv) in the event that a LICENSED PRODUCT and/or LICENSED PROCESS has been approved for commercial sale in an OTHER COUNTRY(IES), but has not been approved for commercial sale in a DEVELOPING COUNTRY(IES), the parties shall promptly meet to discuss, and COMPANY shall commit to M.I.T., in writing with mutually agreed upon timelines (such timelines to be enforceable under this Agreement), that it or an AFFILIATE or SUBLICENSEE will (A) promptly apply for approval for commercial sale of such LICENSED PRODUCT and/or LICENSED PROCESS in such DEVELOPING COUNTRY(IES), and (B) promptly after receiving approval, begin and continue to sell such LICENSED PRODUCT and/or LICENSED PROCESS in such DEVELOPING COUNTRY(IES) at reasonably affordable prices in sufficient volume to meet market demand in such country(ies);

In addition to the remedies set forth in Section 2.2(b) with respect to LICENSED PRODUCTS and LICENSED PROCESSES, in the event COMPANY (or an AFFILIATE or SUBLICENSEE) has failed to fulfill any of its obligations under this Section 3.1(b), M.I.T. may treat such failure as a material reach in accordance with Section 12.3(b), provided that any termination under Section 12.3 for breach of obligations under this Section 3.1(b) shall be limited to COMPANY’s and its AFFILIATE’s licenses and rights under the PATENT RIGHTS for LICENSED PRODUCTS and LICENSED PROCESSES in DEVELOPING COUNTRIES in which such failure has occurred. The termination of COMPANY’s and AFFILIATE’s licenses and rights in such DEVELOPING COUNTRIES for LICENSED PRODUCTS and LICENSED PROCESSES will not affect the remaining terms of this Agreement.

4. ROYALTIES AND PAYMENT TERMS.

4.1 Consideration for Grant of Rights.

And each January 1^st of every year after the first commercial sale of a LICENSED PRODUCT or LICENSED PROCESS				$100,000

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.

(i) Subject to Article 10, COMPANY shall pay to M.I.T. the following amounts upon the first achievement of the following milestones for each LICENSED PRODUCT or LICENSED PROCESS, whether by COMPANY or any of its AFFILIATES or SUBLICENSEES:


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

COMPANY shall notify M.I.T. within [**] days of the achievement of any of the above milestones by COMPANY or any of its AFFILIATES or SUBLICENSEES, such notice to specifically identify the payment obligation.
