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 “CONFIDENTIAL INFORMATION” shall mean any confidential or proprietary information furnished by one party (the “Disclosing Party”) to the other party (the “Receiving Party”) in connection with this Agreement, provided that such information is specifically designated as confidential. 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 2.4.

1.3 “DEVELOPING COUNTRIES” shall mean, within the TERRITORY, the countries designated by The World Bank (www.worldbank.org) as Low-Income Economies, as such list may change from time to time, or any subsequent list that may be mutually agreed to by M.I.T. and COMPANY.

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.

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.

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 an exclusive (subject to Sections 2.2, 2.6 and 3.1(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), 2.6, and 3.1(a), 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.

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 VACCINE PRODUCT for PANDEMIC FLU 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 fifteen (15) days of such inquiry (an “INQUIRY NOTICE”), setting forth the type of VACCINE PRODUCT desired, the commercialization area desired, the name and contact information of the third party, and any other pertinent information. Within six (6) months of such INQUIRY NOTICE, COMPANY or an AFFILIATE shall enter into a sublicense agreement containing commercially reasonable terms and conditions with such third party for the requested VACCINE PRODUCT for PANDEMIC FLU in the requested DEVELOPING COUNTRY(IES). If COMPANY or an AFFILIATE does not grant a sublicense under the PATENT RIGHTS to the third party within six (6) 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 VACCINE PRODUCTS for PANDEMIC FLU 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. For clarity, any license granted by M.I.T. under this Section 2.2(b) shall be solely for bringing VACCINE PRODUCTS for PANDEMIC FLU to market in the requested DEVELOPING COUNTRY(IES) (and other countries mutually agreed to by M.I.T. and COMPANY or AFFILIATE) 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 VACCINE PRODUCTS for PANDEMIC FLU from such DEVELOPING COUNTRY(IES) (and other mutually agreed upon counties) 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 VACCINE PRODUCTS for PANDEMIC FLU from a DEVELOPING COUNTRY(IES) into any other DEVELOPING

COUNTRY(IES) during any period of time in which an adequate supply of such VACCINE PRODUCTS for PANDEMIC FLU at accessible pricing is not available in such other DEVELOPING COUNTRY(IES).

(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 other than a VACCINE PRODUCT for PANDEMIC FLU at affordable prices in one or more DEVELOPING COUNTRIES, M.I.T. and COMPANY shall discuss the request in good faith.

2.3 Option to IMPROVEMENTS. To the extent that an IMPROVEMENT is available for licensing, M.I.T. hereby grants to COMPANY a first option to add any IMPROVEMENT to the PATENT RIGHTS.

M.I.T. shall notify COMPANY in writing, in reasonable detail, of such IMPROVEMENT, furnishing COMPANY a copy of the invention disclosure and/or any related patent application(s). Such notification shall be made within [**] after the M.I.T. Technology Licensing Office receives disclosure of such IMPROVEMENT. Such invention disclosure and any related patent application(s) shall be kept confidential. Notwithstanding the foregoing, M.I.T. shall be under no obligation to file a patent application for any IMPROVEMENT unless COMPANY exercises its option with respect to such IMPROVEMENT.

COMPANY may exercise its right to add such IMPROVEMENT to the PATENT RIGHTS by notifying M.I.T. thereof in writing within [**] months after M.I.T.’s notice of such IMPROVEMENT, provided, however, that COMPANY may, upon written notice to M.I.T., extend such period for up to an additional [**] if the licensing of such IMPROVEMENT remains under bona fide, active consideration by COMPANY (as it may be so extended, the “OPTION PERIOD”). For each IMPROVEMENT so elected, COMPANY shall pay an Improvement Addition Fee of [**] Dollars ($[**]). Upon COMPANY’s exercise of such right and payment of the Improvement Addition Fee, Appendix A shall be deemed to have been amended to add the invention disclosure (and any related patent applications) covering such IMPROVEMENT, and such IMPROVEMENT and any resulting patent applications and patents shall thereafter be included in PATENT RIGHTS for all purposes

of this Agreement. Upon request, M.I.T. shall provide COMPANY with an updated Appendix A for its records.

If COMPANY does not exercise its option within the OPTION PERIOD, M.I.T. shall be free to license its rights to such IMPROVEMENT to any third party.

2.4 Sublicenses.

(a) COMPANY shall have the right to grant sublicenses of its rights under Section 2.1 only during 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 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).

(b) Survival of Sublicense Agreements. M.I.T. agrees that upon termination of this Agreement for any reason, and at the written request of any SUBLICENSEE, M.I.T. will assume COMPANY’s duties and obligations solely with respect to the PATENT RIGHTS under each sublicense agreement granted by COMPANY to such SUBLICENSEE, effective as of the termination date of this Agreement, provided that:

(i) such SUBLICENSEE is not in default of its sublicense agreement with COMPANY at the date of such termination;

(ii) such SUBLICENSEE agrees in writing to be bound to M.I.T. for all obligations, including the payment of royalties, specified in the sublicense agreement;

(iii) M.I.T. shall not assume any obligation of COMPANY to such SUBLICENSEE pursuant to any representation, warranty or indemnification provision; and

(iv) notwithstanding anything to the contrary in the sublicense agreement with

COMPANY, such SUBLICENSEE agrees in writing to M.I.T. within [**] days of the termination of this Agreement to be bound to M.I.T. by the terms and conditions of the following provisions of this Agreement: Articles 3, 5, 8, 9 and 11, and Sections 2.2(b), 6.4, 12.2, 12.3, 12.4, 15.1 and 15.2.

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. If COMPANY desires to seek a waiver of such requirements, upon request of COMPANY, M.I.T. agrees to provide reasonable assistance in the application process for such waiver, however issuance of any such waiver is not guaranteed.

2.6 Retained Rights.

(a) M.I.T. M.I.T. retains the right 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.

(c) Non-assert. COMPANY (including its AFFILIATES) and M.I.T. agree that the PATENT RIGHTS shall not be asserted against any not-for-profit entity using the technology for research purposes only and not for the benefit for any for-profit entity.

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 in OTHER COUNTRIES; thereafter, COMPANY or its AFFILIATES or SUBLICENSEES shall make LICENSED PRODUCTS or LICENSED PROCESSES reasonably available to the public in OTHER COUNTRIES. 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 in OTHER COUNTRIES, specifying the number of staff and other resources to be devoted to such commercialization effort.

(vii) By the [**] anniversary of the EFFECTIVE DATE, COMPANY (or an AFFILIATE or SUBLICENSEE) shall [**].

In the event that COMPANY (or an AFFILIATE or SUBLICENSEE) has failed to fulfill any of its obligations under this Section 3.1(a) at any time prior to COMPANY raising Ten Million Dollars ($10,000,000) from a combination of one or more of the following: the sale of COMPANY’s equity securities for its own account; research and development funds, license fees and/or payments from corporate partners or SUBLICENSEES; and grants from government and non-government sources (the “TERMINATION THRESHOLD”), M.I.T. may treat such failure as a material breach in accordance with Section 12.3(b).

If, at any time after achievement of the TERMINATION THRESHOLD, COMPANY (or an AFFILIATE or SUBLICENSEE) has failed to fulfill any of its obligations under either of Sections 3.1(a)(vi) or 3.1(a)(vii) and such failure has not been remedied within [**] days after receiving written notice thereof from M.I.T., M.I.T. may by written notice to COMPANY convert the license granted to COMPANY pursuant to Section 2.1 hereof to a non-exclusive license, and, in such event, Sections 2.2(a), 6.3 and 7.3 shall have no further effect. Notwithstanding the foregoing, in the event that COMPANY (or an AFFILIATE or SUBLICENSEE) has failed to fulfill any of its obligations under any of Sections 3.1(a)(i),

3.1(a)(ii), 3.1(a)(iv) and 3.1(a)(v) at any time after achievement of the TERMINATION THRESHOLD, M.I.T. may treat such failure as material breach in accordance with Section 12.3(b).

Notwithstanding the foregoing, at any time that M.I.T. notifies COMPANY of its finding that COMPANY has failed to fulfill any of its obligations under this Section 3.1(a), if COMPANY notifies M.I.T. within ten (10) business days that any such failure was the result of circumstances beyond COMPANY’s reasonable control, then, in lieu of M.I.T.’s right to treat such failure as a material breach or to convert this license to a non-exclusive license, respectively, in accordance with this Section, M.I.T. and COMPANY shall negotiate in good faith an amendment to COMPANY’s obligations under this Section 3.1(a). If the parties are unable to negotiate such an amendment within sixty (60) days from the date of COMPANY’s notification pursuant to this Section, then M.I.T. may either treat such failure as a material breach or convert this license to a non-exclusive license in accordance with this Section.

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

(i) Within [**] 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 VACCINE PRODUCTS for PANDEMIC FLU 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 VACCINE PRODUCTS for PANDEMIC FLU in DEVELOPING COUNTRIES in accordance with such plan.

(ii) Within [**] days after 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 VACCINE PRODUCTS for PANDEMIC FLU in DEVELOPING COUNTRIES.

(iii) COMPANY shall use reasonable efforts to either (x) obtain the commitment of its SUBLICENSEES to use diligent efforts to develop and commercialize VACCINE PRODUCTS for PANDEMIC FLU in DEVELOPING COUNTRIES in a manner that is designed to enable availability and accessibility at reasonable cost, or (y) retain rights to develop and commercialize VACCINE PRODUCTS for PANDEMIC FLU in DEVELOPING COUNTRIES.

In addition to the remedies set forth in Section 2.2(b) with respect to VACCINE PRODUCTS, 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 breach in accordance with Section 12.3(b), provided that any termination under Section 12.3(b) 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 VACCINE PRODUCTS for PANDEMIC FLU 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 VACCINE PRODUCTS for PANDEMIC FLU will not affect the remaining terms of this Agreement.

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. on the EFFECTIVE DATE a license issue fee of [**] dollars ($[**]), and, in accordance with Section 6.4, 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) License Maintenance Fees. COMPANY shall pay to M.I.T. the following license maintenance fees during the TERM on the dates set forth below:


January 1, 2009	[	**]
January 1, 2010	[	**]
January 1, 2011	[	**]
January 1, 2012	[	**]


January 1, 2013		[**]
January 1, 2014		[**]
January 1, 2015		[**]
And each January 1^st of every year thereafter	$	150,000

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) COMPANY shall pay to M.I.T. the following amounts upon the first achievement of the following milestones, whether by COMPANY or any of its AFFILIATES or SUBLICENSEES:


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

(ii) The milestone events set forth in Section 4.1(c)(i) above are intended to be successive. In the event that [**]. In addition and notwithstanding the foregoing, if any milestone with respect to a particular LICENSED PRODUCT is reached without achieving a preceding milestone with respect to the

same LICENSED PRODUCT, then the amount which would have been payable on achievement of the preceding milestone shall be payable upon achievement of the next successive milestone. COMPANY shall make such non-refundable, non-creditable milestone payments within [**] days after achievement of each of the milestones. For clarity, each of the milestones set forth above shall be payable only once.

(iii) Notwithstanding the foregoing, in the event that COMPANY receives a milestone payment from a SUBLICENSEE based upon the achievement of a milestone event by the SUBLICENSEE that is essentially equivalent to a milestone event described in Section 4.1(c)(i) above and for which a payment is due to M.I.T. under this Section 4.1(c), COMPANY shall pay to M.I.T. the greater of either (1) the amount set forth in Section 4.1(c)(i) above, or (2) the amount determined in accordance with Section 4.1(e). All other milestone payments from SUBLICENSEES shall be treated in accordance with Section 4.1(e).

(d) Running Royalties. COMPANY shall pay to M.I.T. a running royalty of [**] percent ([**]%) of NET SALES by COMPANY, AFFILIATES and SUBLICENSEES. Running royalties shall be payable for each REPORTING PERIOD and shall be due to M.I.T. within sixty (60) days of the end of each REPORTING PERIOD.

Royalties shall not be due to M.I.T. on NET SALES of (i) VACCINE PRODUCTS in DEVELOPING COUNTRIES, or (ii) any other LICENSED PRODUCTS to the public sector (i.e., governmental, quasi-governmental or non-profit entities providing LICENSED PRODUCTS at a COST BASED PRICE) in DEVELOPING COUNTRIES. As used in this subsection, the term “COST BASED PRICE” means, in respect of each LICENSED PRODUCT, a price not exceeding that which fairly reflects the direct cost of manufacture of such LICENSED PRODUCT plus a typical margin for a generic pharmaceutical product for the respective market. In addition, if, the payment of the royalties set forth in this subsection 4.1(d) on: (1) LICENSED PRODUCTS in DEVELOPING COUNTRIES (other than VACCINE PRODUCTS and sales of LICENSED PRODUCTS to the public sector) or (2) LICENSED PRODUCTS in countries other than MAJOR MARKET COUNTRIES, causes the continued development and commercialization of such LICENSED PRODUCTS in such markets to be economically infeasible in the reasonable judgment of COMPANY, COMPANY shall notify M.I.T., and the parties agree to discuss in good faith a reduction in such royalties in such

markets. 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 royalty obligation. As used in this subsection, the term “MAJOR MARKET COUNTRIES” means the United States, Canada, Japan and the member states of the European Union.

(e) Sharing of SUBLICENSE INCOME. COMPANY shall pay M.I.T. a total of [**] percent ([**]%) of all SUBLICENSE INCOME received by COMPANY or AFFILIATES. Such amount shall be payable for each REPORTING PERIOD in which SUBLICENSE INCOME is received and shall be due to M.I.T. within sixty (60) days of the end of each REPORTING PERIOD.

(f) Consequences of a PATENT CHALLENGE. In the event that (i) COMPANY or any of its AFFILIATES brings a PATENT CHALLENGE against M.I.T., or (ii) COMPANY or any of its AFFILIATES assists another party in bringing a PATENT CHALLENGE against M.I.T. (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 12.4, then: 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.

(g) 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.

(h) Equity.

(i) Initial Grant. COMPANY shall issue a total of Four Hundred and Sixty Thousand (460,000) shares of Common Stock of COMPANY, $.0001 par value per share (“the Shares”), in the name of M.I.T. and of such persons as M.I.T. shall direct (“M.I.T. Holder”), and each M.I.T. Holder shall receive such number of shares as M.I.T. shall direct. Such issuance shall be recorded on the Stock Transfer Ledger of COMPANY on the EFFECTIVE DATE and the Shares shall be delivered to M.I.T. and M.I.T. Holders, if any, within thirty (30) 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 the 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 that the total number of issued and outstanding shares of the COMPANY’s Common Stock shall be calculated to include conversion of all issued and outstanding securities then convertible into Common Stock, the exercise of all then outstanding options and warrants to purchase shares of Common Stock, whether or not then 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, provided that the shares of Common Stock issuable under the terms of the WARRANT described in Section 4.3 shall not be included in such calculation.

(ii) Anti-Dilution Protection. COMPANY shall issue additional shares of Common Stock to M.I.T. and each M.I.T. Holder pro rata, such that M.I.T.’s and each M.I.T. Holders’ aggregate ownership of outstanding Common Stock shall not fall below Five Percent (5%) 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 Five Million Dollars ($5,000,000) in cash in exchange for COMPANY’s capital stock (the “Funding Threshold”) shall be received by COMPANY. Thereafter, no additional shares shall be due to M.I.T. or any M.I.T. Holder pursuant to this Section. For clarity, if a single COMPANY financing causes COMPANY to reach and exceed more than $5,000,000 in cumulative funds raised, then the provisions of this Section shall apply with respect to that portion of such financing up to $5,000,000 and not for that portion of such financing that exceeds such $5,000,000 threshold.

(iii) Participation in Future Private Equity Offerings. After the date of the Funding Threshold, M.I.T. (specifically not including M.I.T. Holders) shall have the right to purchase additional shares of the COMPANY’s equity securities in any private offering by the COMPANY of its equity securities in exchange for cash, to maintain its pro rata ownership as calculated immediately prior to such offering on a Fully Diluted Basis, pursuant to the terms and conditions at least as favorable as those granted to the other offerees. 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 the COMPANY’s Common Stock resulting in gross proceeds to the COMPANY of at least $[**]. M.I.T.’s rights under this Section shall not apply to the

following equity securities: (i) shares of Common Stock issued or issuable to employees, consultants or directors of COMPANY pursuant to an option plan (including shares issued or issuable upon exercise of options already granted); (ii) securities issued in connection with any stock split or stock dividend by COMPANY; (iii) shares of Common Stock issued upon conversion of COMPANY Preferred Stock; (iv) securities issued in consideration for the acquisition or licensing of technology or a corporate partnership transaction or acquisition of another entity; or (v) securities issued in equipment leasing or other debt financing transactions.

(iv) Adjustments for Punitive Round Financings. After the date of the Funding Threshold (the “Funding Threshold Date”) and through the date at which COMPANY has raised a total of Seven Million Five Hundred Thousand Dollars ($7,500,000) in cash in exchange for COMPANY stock, if COMPANY issues Common Stock, or any equity security exercisable for or convertible into Common Stock, such that the price per share of COMPANY’s Common Stock is less than the M.I.T. Share Price (as defined below) (a “Dilutive Issuance”), then immediately following such Dilutive Issuance, COMPANY shall issue to M.I.T. shares of Common Stock such that the M.I.T. Share Number (as defined below) equals the product obtained by multiplying the M.I.T. Share Number in effect immediately before the Dilutive Issuance by the Adjustment Fraction defined below. The M.I.T. Share Price in effect immediately after the Dilutive Issuance shall be adjusted to equal the result obtained by dividing the M.I.T. Share Price in effect immediately before the Dilutive Issuance by the Adjustment Fraction defined below.

The Adjustment Fraction equals:

(A + C)

(A + B)

where:

A = the number of shares of Common Stock issued and outstanding on a Fully Diluted Basis immediately prior to the Dilutive Issuance

B = the number of shares of Common Stock that could be purchased at the M.I.T. Share Price immediately prior to the Dilutive Issuance using the net aggregate consideration received by COMPANY in connection with the Dilutive Issuance

C = the number of shares of Common Stock or of a security exercisable for or convertible into Common Stock issued, on a Fully Diluted Basis, pursuant to the Dilutive Issuance.

Notwithstanding the foregoing, M.I.T.’s rights under this Section shall not apply to the following equity securities: (i) shares of Common Stock issued or issuable to employees, consultants or directors of COMPANY pursuant to an option plan (including shares issued or issuable upon exercise of options already granted); (ii) securities issued in connection with any stock split or stock dividend by COMPANY; (iii) shares of Common Stock issued upon conversion of COMPANY Preferred Stock; (iv) securities issued in consideration for the acquisition or licensing of technology or a corporate partnership transaction or acquisition of another entity; or (v) securities issued in equipment leasing or other debt financing transactions.

In addition, the following definitions shall apply to this Section 4.1(h)(iv):

“Fair Market Value” of a share of Common Stock shall be the highest price per share that the COMPANY could obtain from a willing buyer (not a current employee or director) for shares of Common Stock sold by the COMPANY, from authorized but unissued shares, as determined in good faith by the Board of Directors of the COMPANY, unless the COMPANY shall become subject to a merger, acquisition or other consolidation pursuant to which the COMPANY is not the surviving party, in which case the current fair market value of a share of Common Stock shall be deemed to be the value received by the holders of the COMPANY’s Common Stock for each share of Common Stock pursuant to the COMPANY’s acquisition.

“M.I.T. Share Number” shall mean the number of shares of COMPANY’s Common Stock that M.I.T. owns on the date of the Dilutive Issuance, as adjusted from time to time pursuant to this Section. Notwithstanding the foregoing, any shares of Common Stock acquired by M.I.T. pursuant to Section 4.1(h)(iii) shall not be included in the M.I.T. Share Number.

“M.I.T. Share Price” shall mean the value per share of the shares of Common Stock included in the M.I.T. Share Number, as adjusted from time to time pursuant to this Section. For purposes of this Section, the initial M.I.T. Share Price to be used in an adjustment resulting from the first Dilutive Issuance to occur after the Funding Threshold Date shall be the Fair Market

Value per share of the Common Stock of the COMPANY effective on the Funding Threshold Date.

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.

(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 in the Wall Street Journal) 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 in the Wall Street Journal on the date payment is due.

4.3 Issuance of Warrant. In further consideration of the licenses granted in this Agreement, COMPANY shall, within [**] days after the EFFECTIVE DATE, issue a stock purchase warrant (as described below) to M.I.T. (the “WARRANT”). The WARRANT will be for the purchase of [**] shares of COMPANY Common Stock at a per share exercise price of $[**], and will be exercisable for [**] years after the EFFECTIVE DATE.

5.4 Records. COMPANY shall maintain, and shall cause its AFFILIATES and SUBLICENSEES to maintain, complete and accurate records relating to the rights and obligations under this Agreement and any amounts payable to M.I.T. in relation to this Agreement, which records shall contain sufficient information to permit M.I.T. to confirm the accuracy of any reports delivered to M.I.T. and compliance in other respects with this Agreement. The relevant party shall retain such records for at least [**] years following the end of the calendar year to which they pertain, during which time M.I.T., or M.I.T.’s appointed agents, shall have the right, at M.I.T.’s expense, to inspect such records during normal business hours, and not more than once in any twelve month period, to verify any reports and payments made or compliance in other respects under this Agreement. In the event that any audit performed under this Section reveals an underpayment in excess of [**] percent ([**]%), COMPANY shall bear the full cost of such audit and shall remit any amounts due to M.I.T. within thirty (30) days of receiving notice thereof from M.I.T.

6. PATENT PROSECUTION.

6.1 Responsibility for PATENT RIGHTS. M.I.T. shall prepare, file, prosecute, and maintain all of the PATENT RIGHTS.

7. INFRINGEMENT.

7.1 Notification of Infringement. Each party agrees to provide written notice to the other party promptly after becoming aware of any infringement of the PATENT RIGHTS.

7.2 Right to Prosecute Infringements.

(a) COMPANY Right to Prosecute. So long as COMPANY remains the exclusive licensee of the PATENT RIGHTS in the FIELD in the TERRITORY, COMPANY, to the extent permitted by law, shall have the right, under its own control and at its own expense, to prosecute any third party infringement of the PATENT RIGHTS in the FIELD in the TERRITORY, subject to Sections 7.4 and 7.5. If required by law, M.I.T. shall permit any action under this Section to be brought in its name, including being joined as a party-plaintiff, provided that COMPANY shall hold M.I.T. harmless from, and indemnify M.I.T. against, any costs, expenses, or liability that M.I.T. 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 the public interest. COMPANY shall not enter into any settlement, consent judgment, or other voluntary final disposition of any infringement action under this Section without the prior written consent of M.I.T., not to be unreasonably withheld.

(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. Prior to commencing any such actions, M.I.T. shall consult with COMPANY and shall consider the views of COMPANY regarding the advisability of the proposed action. Further, M.I.T. shall not enter into any settlement, consent judgment, or other voluntary final disposition of any infringement action under this Section without first consulting with and considering the views of 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 revenues to COMPANY pursuant to such sublicense shall be treated as set forth in Article 4.

8. INDEMNIFICATION AND INSURANCE

8.1 Indemnification.

(a) Indemnity. COMPANY shall indemnify, defend, and hold harmless M.I.T. and its trustees, officers, faculty, students, employees, and agents and their respective successors, heirs and assigns (the “Indemnitees”), against any liability, damage, loss, or expense (including reasonable attorneys’ fees and expenses) (collectively, “LOSSES”) incurred by or imposed upon any of the Indemnitees in connection with any claims, suits, investigations, actions, demands or judgments 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; provided, however, that COMPANY shall have no obligation pursuant to the foregoing with respect to any LOSSES that result from the gross negligence or willful misconduct of any Indemnitee.

(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. informed of the progress in the defense and disposition of such claim and to consult with M.I.T. with regard to any proposed settlement.

SUBLICENSEE is making, using or selling a LICENSED PRODUCT or a LICENSED PROCESS, including conducting clinical trials or obtaining any required regulatory approvals, 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 such insurance shall not be less than [**] Dollars ($[**]) per occurrence with an aggregate of [**] Dollars ($[**]) for bodily injury including death; and [**] Dollars ($[**]) per occurrence with an aggregate of [**] Dollars ($[**]) for property damage; and [**] Dollars ($[**]) per occurrence with an aggregate of [**] Dollars ($[**]) for errors and omissions, provided that such errors and omissions coverage shall only be required to be obtained if COMPANY or an AFFILIATE or SUBLICENSEE provides services in connection with a LICENSED PRODUCT or LICENSED PROCESS. In the alternative, COMPANY may self-insure subject to prior approval of M.I.T.

COMPANY shall provide M.I.T. with Certificates of Insurance evidencing compliance with this Section. COMPANY shall continue to maintain such insurance or self-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.

9. NO REPRESENTATIONS OR WARRANTIES

M.I.T. hereby represents and warrants to COMPANY as of the EFFECTIVE DATE that, subject to Section 2.6, to its knowledge (i) all inventors of record that are employees of M.I.T. have assigned or are obligated to assign to M.I.T. their entire right, title and interest in the PATENT RIGHTS, and M.I.T. has the authority to grant the licenses as granted herein; and (ii) it has not granted to any third party any rights under the PATENT RIGHTS that would conflict with this Agreement.

M.I.T.’s total liability under the representations and warranties of this Agreement shall be limited to an amount equal to the total sum that has been paid by COMPANY to M.I.T. under the provisions of Article 4 of this Agreement.

EXCEPT AS MAY OTHERWISE BE EXPRESSLY SET FORTH IN THIS AGREEMENT, M.I.T. MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE PATENT RIGHTS, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A

PARTICULAR PURPOSE, NONINFRINGEMENT, VALIDITY OF PATENT RIGHTS CLAIMS, WHETHER ISSUED OR PENDING, AND THE ABSENCE OF LATENT OR OTHER DEFECTS, WHETHER OR NOT DISCOVERABLE. Specifically, and not to limit the foregoing, M.I.T. makes no warranty or representation (i) regarding the validity or scope of the PATENT RIGHTS, and (ii) that the exploitation of the PATENT RIGHTS or any LICENSED PRODUCT or LICENSED PROCESS will not infringe any patents or other intellectual property rights of M.I.T. or of a third party.

IN NO EVENT SHALL M.I.T., ITS TRUSTEES, DIRECTORS, OFFICERS, EMPLOYEES AND AFFILIATES BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY KIND, INCLUDING ECONOMIC DAMAGES OR INJURY TO PROPERTY AND LOST PROFITS, REGARDLESS OF WHETHER M.I.T. SHALL BE ADVISED, SHALL HAVE OTHER REASON TO KNOW, OR IN FACT SHALL KNOW OF THE POSSIBILITY OF THE FOREGOING.

10. ASSIGNMENT.

This Agreement is personal to COMPANY and no rights or obligations may be assigned by COMPANY without the prior written consent of M.I.T. Notwithstanding the foregoing, COMPANY may assign its rights and obligations under this Agreement to an AFFILIATE or to a successor in connection with the merger, consolidation, or sale of all or substantially all of its assets or that portion of its business to which this Agreement relates; provided, however, that (i) COMPANY shall deliver written notice to M.I.T. within [**] days of any such assignment, such notice to include the assignee’s contact information, and (ii) this Agreement shall immediately terminate if the assignee fails to agree in writing to M.I.T. to be bound by the terms and conditions of this Agreement within [**] days of the effective date of the assignment.

(c) Pre-termination Obligations. In no event shall termination of this Agreement release COMPANY, AFFILIATES, or SUBLICENSEES from the obligation to pay any amounts that became due on or before the effective date of termination.

13. DISPUTE RESOLUTION.

13.1 Mandatory Procedures. The parties agree that any dispute arising out of or relating to this Agreement shall be resolved solely by means of the procedures set forth in this Article, and that such procedures constitute legally binding obligations that are an essential provision of this Agreement. If either party fails to observe the procedures of this Article, as may be modified by their written agreement, the other party may bring an action for specific performance of these procedures in any court of competent jurisdiction.

13.2 Equitable Remedies. Although the procedures specified in this Article are the sole and exclusive procedures for the resolution of disputes arising out of or relating to this Agreement, either party may seek a preliminary injunction or other provisional equitable relief if, in its reasonable judgment, such action is necessary to avoid irreparable harm to itself or to preserve its rights under this Agreement.

13.3 Dispute Resolution Procedures

(a) Mediation. In the event any dispute arising out of or relating to this Agreement remains unresolved within [**] days from the date the affected party informed the other party of such dispute, either party may initiate mediation upon written notice to the other party (“Notice Date”), whereupon both parties shall be obligated to engage in a mediation proceeding under the then current Center for Public Resources (“CPR”) Model Procedure for Mediation of Business Disputes (http://www.cpradr.org), except that specific provisions of this Article shall override inconsistent provisions of the CPR Model Procedure. The mediator will be selected from the CPR Panels of Neutrals. If the parties cannot agree upon the selection of a mediator within fifteen (15) business days after the Notice Date, then upon the request of either party, the CPR shall appoint the mediator. The parties shall attempt to resolve the dispute through mediation until the first of the following occurs: (i) the parties reach a written settlement; (ii) the mediator notifies the parties in writing that they have reached an impasse; (iii) the parties agree in writing that they have reached an impasse; or (iv) the parties have not reached a settlement within [**] days after the Notice Date.

(b) Trial Without Jury. If the parties fail to resolve the dispute through mediation, or if neither party elects to initiate mediation, each party shall have the right to pursue any other remedies legally available to resolve the dispute, provided, however, that the parties expressly waive any right to a jury trial in any legal proceeding under this Article.

13.4 Performance to Continue. Each party shall continue to perform its undisputed obligations under this Agreement pending final resolution of any dispute arising out of or relating to this Agreement; provided, however, that a party may suspend performance of its undisputed obligations during any period in which the other party fails or refuses to perform its undisputed obligations. Nothing in this Article is intended to relieve COMPANY from its obligation to make undisputed payments pursuant to Articles 4 and 6 of this Agreement.

13.5 Statute of Limitations. The parties agree that all applicable statutes of limitation and time-based defenses (such as estoppel and laches) shall be tolled while the procedures set forth in Sections 13.3(a) are pending. The parties shall cooperate in taking any actions necessary to achieve this result.

14. CONFIDENTIAL INFORMATION

14.1 Designation. CONFIDENTIAL INFORMATION that is disclosed in writing shall be marked with a legend indicating its confidential status (such as “Confidential” or “Proprietary”). CONFIDENTIAL INFORMATION that is disclosed orally or visually shall be documented in a written notice prepared by the Disclosing Party and delivered to the Receiving Party within [**] days of the date of disclosure; such notice shall summarize the CONFIDENTIAL INFORMATION disclosed to the Receiving Party and reference the time and place of disclosure.

14.2 Obligations. For a period of [**] years after termination or expiration of this Agreement, the Receiving Party shall (i) maintain such CONFIDENTIAL INFORMATION in strict confidence, except that the Receiving Party may disclose or permit the disclosure of any CONFIDENTIAL INFORMATION to its directors, officers, employees, consultants, and advisors who are obligated to maintain the confidential nature of such CONFIDENTIAL INFORMATION and who need to know such CONFIDENTIAL INFORMATION for the purposes of this Agreement; (ii) use such CONFIDENTIAL INFORMATION solely for the purposes of this Agreement; and (iii) allow its trustees or directors, officers, employees, consultants, and advisors to reproduce the CONFIDENTIAL INFORMATION only to the extent necessary for the purposes of this Agreement, with all such reproductions being considered CONFIDENTIAL INFORMATION.

14.3 Exceptions. The obligations of the Receiving Party under Section 14.2 above shall not apply to the extent that the Receiving Party can demonstrate that certain CONFIDENTIAL INFORMATION (i) was in the public domain prior to the time of its disclosure under this Agreement; (ii) entered the public domain after the time of its disclosure under this Agreement through means other than an unauthorized disclosure resulting from an act or omission by the Receiving Party; (iii) was independently developed or discovered by the Receiving Party without use of the CONFIDENTIAL INFORMATION; (iv) is or was disclosed to the Receiving Party at any time, whether prior to or after the time of its disclosure under this Agreement, by a third party having no fiduciary relationship with the Disclosing Party and having no obligation of confidentiality with respect to such CONFIDENTIAL INFORMATION; or (v) is required to be disclosed to comply with applicable laws or regulations, or with a court or

administrative order, provided that the Disclosing Party receives reasonable prior written notice of such disclosure.

14.4 Ownership and Return. The Receiving Party acknowledges that the Disclosing Party (or any third party entrusting its own information to the Disclosing Party) claims ownership of its CONFIDENTIAL INFORMATION in the possession of the Receiving Party. Upon the expiration or termination of this Agreement, and at the request of the Disclosing Party, the Receiving Party shall return to the Disclosing Party all originals, copies, and summaries of documents, materials, and other tangible manifestations of CONFIDENTIAL INFORMATION in the possession or control of the Receiving Party, except that the Receiving Party may retain one copy of the CONFIDENTIAL INFORMATION in the possession of its legal counsel solely for the purpose of monitoring its obligations under this Agreement.

(b) The state and federal courts having jurisdiction over Cambridge, MA, USA, provide the exclusive forum for any PATENT CHALLENGE and/or any court action between the parties relating to this Agreement. COMPANY and M.I.T. each submits to the jurisdiction of such courts and waives any claim that such court lacks jurisdiction over COMPANY or its AFFILIATES (on the one hand) or M.I.T. (on the other hand) or constitutes an inconvenient or improper forum.

15.3 Force Majeure. Neither party will be responsible for delays resulting from causes beyond the reasonable control of such party, including without limitation fire, explosion, flood, war, strike, or riot, provided that the nonperforming party uses commercially reasonable efforts to avoid or remove such causes of nonperformance and continues performance under this Agreement with reasonable dispatch whenever such causes are removed.

15.4 Amendment and Waiver. This Agreement may be amended, supplemented, or otherwise modified only by means of a written instrument signed by both parties. Any waiver of

any rights or failure to act in a specific instance shall relate only to such instance and shall not be construed as an agreement to waive any rights or fail to act in any other instance, whether or not similar.

15.5 Severability. In the event that any provision of this Agreement shall be held invalid or unenforceable for any reason, such invalidity or unenforceability shall not affect any other provision of this Agreement, and the parties shall negotiate in good faith to modify the Agreement to preserve (to the extent possible) their original intent. If the parties fail to reach a modified agreement within [**] days after the relevant provision is held invalid or unenforceable, then the dispute shall be resolved in accordance with the procedures set forth in Article 13. While the dispute is pending resolution, this Agreement shall be construed as if such provision were deleted by agreement of the parties.

15.6 Binding Effect. This Agreement shall be binding upon and inure to the benefit of the parties and their respective permitted successors and assigns.

15.7 Headings. All headings are for convenience only and shall not affect the meaning of any provision of this Agreement.

15.8 Entire Agreement. This Agreement constitutes the entire agreement between the parties with respect to its subject matter and supersedes all prior agreements or understandings between the parties relating to its subject matter.

IN WITNESS WHEREOF, the parties have caused this Agreement to be executed by their duly authorized representatives.

The EFFECTIVE DATE of this Agreement is April 28, 2008.

CONFLICT AVOIDANCE STATEMENT

Dept. or Lab:		Biological Engineering

Company:		Parasol

Address:		1000 Winter Street Waltham, MA 02451

Licensed Technology: [**]

Because of the M.I.T. license granted to the above company and my equity* position and continuing relationship with this company, I acknowledge the potential for a possible conflict of interest between the performance of research at M.I.T. and my contractual or other obligations to this company. Therefore, I will not:

use students at M.I.T. for research and development projects for the company;

restrict or delay access to information from my M.I.T. research;

take direct or indirect research support from the company in order to support my activities at M.I.T.; or

employ students at the company, except in accordance with Section 4.5.2, “Faculty and Students,” in the Policies and Procedure Guide.

In addition, in order to avoid the appearance of a conflict, I will attempt to differentiate clearly between the intellectual directions of my M.I.T. research and my contributions to the company. To that end, I will expressly inform my department head/laboratory director annually of the general nature of my activities on behalf of the company.
