In the event that the obligations under this Section 3.1 have not been fulfilled, then M.I.T. may treat such failure as a material breach in accordance with Section 12.3(b).

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 6.3,

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 on the dates set forth below:


January 1, 2003	$	[**]
January 1, 2004	$	[**]
and each January 1 of every year thereafter	$	[**]

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.

(c) Running Royalties. COMPANY shall pay to M.I.T. a running royalty of [**] percent ([**]%) of NET SALES by COMPANY and its AFFILIATES. 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. For each Licensed Product sold, COMPANY shall have the right to credit against Running Royalties due to M.I.T. [**] percent ([**]%) of the royalties paid to third parties for that Product; provided however, that the royalties paid to M.I.T. shall not be less than [**] percent ([**]%) of the Net Sales of that Licensed Product.

The foregoing notwithstanding, if, in any calendar year, the royalty proceeds to M.I.T. pursuant to this Section 4.1(c) reach the sum of [**] Dollars ($[**]), then the royalty rate that shall be applied to any additional NET SALES during that same calendar year shall be reduced to [**] of the amount specified in the first paragraph of this Section 4.1(c). Furthermore, if, in any calendar year, the royalty proceeds to M.I.T. pursuant to this Section 4.1(c) reach the sum of [**] Dollars ($[**]), then the royalty rate that shall be applied to any additional NET SALES during that same calendar year shall be reduced to [**] of the amount specified in the first paragraph of this Section 4.1(c).

(d) Sharing of SUBLICENSE INCOME. COMPANY shall pay M.I.T. a total of [**] percent ([**]%) of all SUBLICENSE INCOME received by COMPANY or AFFILIATES, excluding running royalties on NET SALES of SUBLICENSEES. Such amount shall be payable for each REPORTING PERIOD and shall be due to M.I.T. within [**] days of the end of each REPORTING PERIOD.

(e) 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.

(f) Equity.

(i) Initial Grant. COMPANY shall issue a total of Two Hundred Thousand (200,000) shares of Common Stock of COMPANY, $.001 par value per share, (the "Shares") in the name of M.I.T. and no more that five (5) 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.

COMPANY represents to M.I.T. that, as of the Effective Date, the aggregate number of Shares equals at least [**] Percent ([**]%) of the COMPANY's issued and outstanding Common Stock calculated on a "Fully Diluted Basis." For purposes of this Section 4.1(f), "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 and the exercise of all then

outstanding options and warrants to purchase shares of common stock, whether or not then exercisable.

(ii) Participation in Future Private Equity Offerings. M.I.T. (specifically not including M.I.T. Holders) shall have the right to purchase, pursuant to terms and conditions at least as favorable as those granted to other offerees, a sufficient number of shares of the COMPANY's equity securities in the first equity financing of the COMPANY after the date hereof such that immediately following such offering M.I.T. would own at least the same percentage, on a Fully Diluted Basis, of the COMPANY's issued and outstanding Common Stock that it owned immediately prior to such offering. M.I.T. shall be considered to have waived its participation right if it fails to respond within [**] business days following its receipt of a representative package of due diligence information and a term sheet for such an offering. In addition, whether or not M.I.T. elects to participate in such first equity offering, M.I.T. shall have the right to become a party the investors rights agreement, or the like, among the COMPANY and the purchasers of such equity securities to the extent it provides to M.I.T. preemptive rights to purchase a sufficient number of additional securities in future equity offerings to maintain its percentage ownership of the common stock of the COMPANY on a Fully Diluted Basis. Until such investors rights agreement is entered into in connection with an equity financing of the COMPANY, M.I.T. shall continue to maintain its rights in subsequent offerings to purchase a sufficient number of equity securities of the COMPANY such that immediately following such offering M.I.T. would own at least the same percentage, on a Fully Diluted Basis, of the COMPANY's issued and outstanding Common Stock that it owned immediately prior to such offering. All rights granted to M.I.T. pursuant to this Section 4.1(f)(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 $[**].

(iii) Adjustments for Punitive Round Financings. After the date of the Funding Threshold (the "Funding Threshold Date"), if, as a result of the issuance by the COMPANY of Common Stock, or any equity security exercisable for or convertible into Common Stock, the conversion rate into Common Stock of any outstanding shares of convertible preferred stock of the COMPANY issued on or before the Funding Threshold Date is adjusted pursuant to an antidilution adjustment included in the Certificate of Incorporation of the COMPANY, the COMPANY will issue to M.I.T. for each share of Common Stock issued pursuant to Section 4.1(f)(i) and held by M.I.T. a share and/or fractional share of Common Stock equal to the additional share and/or fractional share of Common Stock which a holder of such convertible preferred stock would be entitled to receive as a result of such adjustment of the conversion rate included in the COMPANY's Certificate of Incorporation as if such holder converted his share of convertible preferred stock into Common Stock immediately after such adjustment, whether or not such conversion is actually exercised at the time of the dilutive issuance adjustment.

Notwithstanding the above, if the issuance by the COMPANY of Common Stock, or any equity security exercisable for or convertible into Common Stock, would have caused an adjustment in the conversion rate included in the COMPANY's Certificate of Incorporation but for the waiver of such adjustment by the holders of such convertible preferred stock (the "Preferred Holders") or the effect of any so called "pay to play" provision, then upon such issuance, if M.I.T., in its own discretion, does not also waive such adjustment, the Company shall issue to M.I.T. such additional shares of Common Stock that M.I.T. would have been issued as set forth above had the Preferred Holders not waived such adjustment or the effect of the pay to play provision had not precluded such adjustment. Thereafter, the conversion rate of the preferred stock shall be deemed to have been adjusted notwithstanding the waiver

or preclusion of such adjustment for purposes of determining whether or not future issuances by the COMPANY of Common stock, or any equity security exercisable for or convertible into Common Stock, should require the COMPANY to issue additional shares of Common Stock to M.I.T.

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 14.1. Each payment should reference this Agreement and identify the obligation under this Agreement that the payment satisfies.

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 two percentage points above the Prime Rate of interest as reported in the Wall Street Journal on the date payment is due.

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.

(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 a reasonable time 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.

7.3 Declaratory Judgment Actions. In the event that a declaratory judgment action is brought against M.I.T. or COMPANY by a third party alleging invalidity, unenforceability, or non-infringement of the PATENT RIGHTS, M.I.T., at its option, shall have the right within [**] days after commencement of such action to take over the sole defense of the action at its own expense. If M.I.T. does not exercise this right, COMPANY may take over the sole defense of the action at COMPANY's sole expense, subject to Sections 7.4 and 7.5.

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 or had entered into a sublicense agreement with the infringer, and (iii) as to special or punitive damages, the parties shall share equally in any award.

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 Section 4.1(d).

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) incurred by or imposed upon any of the Indemnitees in connection with any claims, suits, actions, demands or judgments arising out of any theory of liability (including without limitation actions in the form of tort, warranty, or strict liability and regardless of whether such action has any factual basis) concerning any product, process, or service that is made, used, sold, imported, or performed pursuant to any right or license granted under this Agreement.

(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.

8.2 Insurance. COMPANY shall obtain and carry in full force and effect commercial general liability insurance, including product liability and errors and omissions 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 Commonwealth of Massachusetts or an insurer pre-approved by M.I.T., such approval not to be unreasonably withheld, (ii) shall list M.I.T. as an additional insured thereunder, (iii) shall be endorsed to include product liability coverage, and (iv) shall require thirty (30) 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 One Million Dollars ($1,000,000) per occurrence with an aggregate of Three Million Dollars ($3,000,000) for bodily injury including death; One Million Dollars ($1,000,000) per occurrence with an aggregate of Three Million Dollars ($3,000,000) for property damage; and One Million Dollars ($1,000,000) per occurrence with an aggregate of Three Million Dollars ($3,000,000) for errors and omissions. 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 five (5) years.

9. NO REPRESENTATIONS OR WARRANTIES

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 OR COMPANY, ITS DIRECTORS, OFFICERS, ADVISORS, 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 ANY SUCH ENTITY OR PERSON 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 this Agreement in connection with the sale or transfer of all or substantially all of COMPANY's business relating to the LICENSED PRODUCTS and LICENSED PROCESSES, whether by merger, consolidation, sale of assets or otherwise; provided that (a) the assignee shall agree in writing to be bound by the terms and conditions hereof prior to such assignment and (b) the total valuation of the COMPANY is at least [**] Dollars ($[**]). In the event that the total valuation of the COMPANY is less than $[**], then the assignment may be made only with M.I.T.'s written permission. Failure of such assignee to so agree to be bound by the terms and conditions hereof shall be grounds for termination by M.I.T. under Section 12.3.

11. GENERAL COMPLIANCE WITH LAWS

COMPANY hereby gives written assurance that it will comply with, and will cause its AFFILIATES and SUBLICENSEES to comply with, all United States export control laws and regulations, that it bears sole responsibility for any violation of such laws and regulations by itself or its AFFILIATES or SUBLICENSEES, and that it will indemnify, defend, and hold M.I.T. harmless (in accordance with Section 8.1) for the consequences of any such violation.

11.3 Non-Use of M.I.T. Name. COMPANY and its AFFILIATES and SUBLICENSEES shall not use the name of "Massachusetts Institute of Technology," "Lincoln Laboratory" or any variation, adaptation, or abbreviation thereof, or of any of its trustees, officers, faculty, students, employees, or agents, or any trademark owned by M.I.T., or any terms of this Agreement in any promotional material or other public announcement or disclosure without the prior written consent of M.I.T. The foregoing notwithstanding, without the consent of M.I.T., COMPANY may state that it is licensed by M.I.T. under one or more of the patents and/or patent applications comprising the PATENT RIGHTS.

11.4 Marking of LICENSED PRODUCTS. To the extent commercially feasible and consistent with prevailing business practices, COMPANY shall xxxx, and shall cause its AFFILIATES and SUBLICENSEES to xxxx, all LICENSED PRODUCTS that are manufactured or sold under this Agreement with the number of each issued patent under the PATENT RIGHTS that applies to such LICENSED PRODUCT.

12. TERMINATION

12.1 Voluntary Termination by COMPANY. COMPANY shall have the right to terminate this Agreement, for any reason, (i) upon at least six (6) months prior written notice to M.I.T., such notice to state the date at least six (6) months in the future upon which termination is to be effective, and (ii) upon payment of all amounts due to M.I.T. through such termination effective date.

(b) Material Breach. In the event COMPANY commits a material breach of its obligations under this Agreement, except for breach as described in Section 12.3(a), and fails to cure that breach within [**] days after receiving written notice thereof, M.I.T. may terminate this Agreement immediately upon written notice to COMPANY.

12.4 Effect of Termination.

(a) Survival. The following provisions shall survive the expiration or termination of this Agreement: Articles 1, 8, 9, 13 and 14, and Sections 4.1(f), 5.2 (obligation to provide final report and payment), 5.4, 11.1, 11.2 and 12.4.

(b) Inventory. Upon the early termination of this Agreement, COMPANY and its AFFILIATES and SUBLICENSEES may complete and sell any work-in-progress and inventory of LICENSED PRODUCTS that exist as of the effective date of termination, provided that (i) COMPANY pays M.I.T. the applicable running royalty or other amounts due on such sales of LICENSED PRODUCTS in accordance with the terms and conditions of this Agreement, and (ii) COMPANY and its AFFILIATES and SUBLICENSEES shall complete and sell all work-in-progress and inventory of LICENSED PRODUCTS within [**] months after the effective date of termination.

(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 (xxxx://xxx.xxxxxx.xxx), 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 [**] 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. MISCELLANEOUS.

questions affecting the construction and effect of any patent shall be determined by the law of the country in which the patent shall have been granted.

14.3 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.

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

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:

1): use students at M.I.T. for research and development projects for the company;
2): restrict or delay access to information from my M.I.T. research;
3): take direct or indirect research support from the company in order to support my activities at M.I.T.; or
4): employ students at the company, except in accordance with Section 4.5.2, "Faculty and Students," in the Policies and Procedures 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.

SECOND AMENDMENT

This Second Amendment is entered into this 25th day of July, 2008 (the "Effective Date") and amends the Exclusive Patent License Agreement dated December 4, 2001 (the "2001 License Agreement") by and between the Massachusetts Institute of Technology, a corporation duly organized and existing under the laws of the Commonwealth of Massachusetts and having its principal office at 00 Xxxxxxxxxxxxx Xxxxxx, Xxxxxxxxx, Xxxxxxxxxxxxx 00000, X.X.X. ("M.I.T."), and A123 Systems, Inc., a Delaware corporation having its principal office at 000 Xxxxxxx Xxxxxx, Xxxxxxxxx, XX 00000 ("COMPANY").

WHEREAS, M.I.T. and COMPANY wish to amend the 2001 License Agreement in order to redefine the royalty terms;

NOW, THEREFORE, in consideration of the premises and the mutual covenants contained herein, the parties agree to amend the 2001 License Agreement as follows:

1. Establish a new definition as follows and add as a new Section 1.13:

1.13 "ROYALTY BASE" shall mean the total manufacturing cost, as determined by Generally Accepted Accounting Principles (GAAP), of all battery cathode powder material produced or acquired by COMPANY and/or AFFILIATES where such battery cathode powder material is used in a battery electrode that is a LICENSED PRODUCT.

2. The present Section 4.1(c) shall be deleted in its entirety and replaced with the following new Section 4.1(c):

(c) Running Royalties. (i) Commencing as of the Effective Date, for any LICENSED PRODUCTS that include battery cathode powder material produced or acquired by COMPANY and/or AFFILIATES, COMPANY shall pay to M.I.T. a running royalty of [**] percent ([**]%) of the ROYALTY BASE. No other running royalties shall be due MIT with respect to such LICENSED PRODUCTS. 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. During each such REPORTING PERIOD, COMPANY shall have the right to credit against Running Royalties due to M.I.T. [**] percent ([**]%) of any other royalty COMPANY is required to pay for the same battery cathode powder material to (i) M.I.T. pursuant to another license agreement and/or (ii) a third party; provided that under no circumstance shall the royalty due to M.I.T. under this Section 4.1(c) be less that [**] percent ([**]%) of the ROYALTY BASE.

(ii) Should the COMPANY and its AFFILIATES have NET SALES of LICENSED PRODUCTS that do not contain battery cathode powder material produced or acquired by COMPANY and/or AFFILIATES and used in a battery electrode and for which the ROYALTY BASE is therefore not applicable, then the COMPANY and M.I.T. shall meet in good faith to revise and expand the definition of the ROYALTY BASE and the terms of this Section 4.1(c) to include such LICENSED PRODUCTS under mutually agreeable terms, provided that any running royalty applicable to such LICENSED PRODUCTS shall not exceed [**] percent ([**]%) of NET SALES.

3. The present Section 5.2 shall be deleted and replaced with the following new Section 5.2:

5.2 Content of Reports and Payments. Each report delivered by COMPANY to M.I.T. shall contain at least the following information for the immediately preceding REPORTING PERIOD, only to the extent that such information may be applicable to such REPORTING PERIOD:

(ii) a description of LICENSED PROCESSES performed by COMPANY and its AFFILIATES in each country as may be pertinent to a royalty accounting hereunder;

(iii) calculation of the ROYALTY BASE for the applicable REPORTING PERIOD;

(iv) calculation of NET SALES for the applicable REPORTING PERIOD in each country, including a listing of applicable deductions;

(v) total royalty payable on the ROYALTY BASE in U.S. dollars, together with the exchange rates used for conversion;

(vi) the amount of SUBLICENSE INCOME received by COMPANY and AFFILIATES from each SUBLICENSEE and the amount due to M.I.T. from such SUBLICENSE INCOME, including an itemized breakdown of the sources of income comprising the SUBLICENSE INCOME; and

(vii) the number of sublicenses entered into for the PATENT RIGHTS.

If no amounts are due to M.I.T. for any REPORTING PERIOD, the report shall so state.

Such report shall only include the information set forth in subparagraphs (i), (ii) and (iv) above if the running royalties are calculated in accordance with Section 4.1 (c) (ii) above.

4. COMPANY'S notice address in the present Section 14.1 shall be deleted in its entirety and replaced with the following:

A123 Systems, Inc. 000 Xxxxxxx Xxxxxx, Xxxxxxxxx, XX 00000 Attention: General Counsel
Tel: (617) 000- 0000

5. On or before [**], COMPANY shall make a [**] payment of [**] Dollars ($[**]) to M.I.T. in consideration of redefining the royalty terms under this Second Amendment.

6. The remaining terms and conditions of the 2001 License Agreement remain in effect.
