PATENT SUBLICENSE AGREEMENT

THIS PATENT SUBLICENSE AGREEMENT ("Agreement") is entered into by and among:

LiFePO4+C Licensing AG, a Swiss corporation having a place of business at Rothausstrasse 61, 4132 Muttenz, Switzerland ("Licensor"); and

A123 Systems, Inc., a Delaware corporation having a place of business at 200 West Street, Waltham, MA, United States of America 02451 ("A123"; A123 and its Related Corporations shall be collectively referred to as "Licensee").

Licensor and Licensee shall each be a "Party" and shall be collectively referred to as the "Parties".

BACKGROUND

A. Licensor has obtained a worldwide license or sublicense from Hydro-Québec, the Université de Montréal and the Centre National de la Recherche Scientifique to the Licensor Licensed Patent Rights (as defined below) for the manufacture, importation, exportation, sale and use of Licensed Products (as defined below) (the "Head License Agreement"). Licensor's Head License Agreement includes the limited right to grant sublicenses to third parties under the Licensor Licensed Patent Rights for certain fields of application.

B. Licensee is interested in obtaining a worldwide non-exclusive sublicense to the Licensor Licensed Patent Rights in said fields of application in order to have the right to sell Licensed Products in specific circumstances and to incorporate Licensed Products into Electrode Systems, Cells, Complex Systems and other products (as set forth below) and to market and sell such products.

C. Licensee is prepared and intends to use commercially reasonable efforts to continue existing and to further develop commercially effective, reasonably funded (as compared to other similarly situated companies), ongoing and active manufacturing, marketing and sales programs in connection with the products.

D. In the course of negotiations leading to the execution of this Agreement, Licensors offered to Licensee the choice of being granted a license to the Goodenough Patent Rights, the NTT Patent Rights, and the Carbon Coating Patent Rights separately without being obliged to be granted a license to all of these patents as a package. For commercial reasons, Licensee has chosen to be granted a license to all of these patents.

E. A123 and Hydro-Québec are engaged, with others, in a number of judicial and administrative disputes pending in the courts and agencies of the United States of America. The Parties wish to resolve these disputes and settle the claims pending therein through, in part, the creation of this Agreement and the performance of the obligations set forth herein.

5. PATENT RIGHTS.

5.1 Claims or Challenges. A123 acknowledges that it has been provided Sections 9.4 and 9.7 of the license agreement between NTT and HQ regarding the NTT Patent License, such Sections 9.4 and 9.7 being attached hereto as Appendix E.

5.2 Information. Licensee shall immediately notify Licensor, in writing, if it becomes aware of any suspected infringement of the Licensor Licensed Patent Rights.

5.3 Cooperation between the Parties. Each Party shall cooperate fully as reasonably necessary with the other in connection with any litigation (except with respect to litigation against an existing customer or business partner of such Party) asserting the Licensor Licensed Patent Rights or the A123 Patent Rights in a manner that will preserve attorney-client privilege, professional secret and attorney work protection thereto. Unless

prohibited by applicable laws, each Party shall cooperate fully in such litigation with all discovery requests permissible under applicable laws, regardless of whether such compliance is legally required by applicable laws. Excepted "existing customers or business partners" of Licensee shall include, without limitation, Licensee's customers or business partners or entities to whom Licensee has submitted a written proposal or with whom Licensee has a product evaluation agreement or confidentiality agreement at the time such litigation is initiated or such assistance is requested, whichever is earlier.

With respect to a Party's excepted existing customers or business partners, no duty of cooperation shall exist and any information available to that Party regarding the excepted existing customer or business partner or the Party's relationship with that entity must be obtained through third party discovery processes as provided by the relevant court or judicial body. This Section 5.3 provides no special exemptions from such discovery processes with respect to information available to a Party regarding an excepted existing customer or business partner. or the Party's relationship with that entity.

5.4 Enforcement. If after the Effective Date of this Agreement, Licensee provides written notice to Licensor (the "Infringement Notice") that it has actual knowledge or good faith belief that a Third Party, who is a direct competitor of Licensee in phosphate-based products for a material business opportunity, is infringing the Licensor Licensed Patent Rights based upon grounds identified and described in the Infringement Notice, that, to Licensee's knowledge such Third Party is not a licensee of the Licensor Licensed Patent Rights, and that Licensee entered a competitive bid and was forced to lower its bid price due to a lower bid by the Third Party, as demonstrated by written evidence, then Licensor will be required to inform Licensee in writing within [***] of receiving such Infringement Notice whether it will elect to commence enforcement actions against such Third Party for such infringement (the "Response Notice") and shall actually execute such enforcement action(s) as soon as reasonably possible, in no event later than [***] after the date that Licensor received the Infringement Notice (the "Enforcement Period"). Such enforcement actions may include [***], but are not required to include [***]. For purposes of clarity, Licensee shall further be required to identify, in the Infringement Notice, the jurisdictions served by the competitive bid. If Licensor fails to undertake such enforcement actions by the end of the Enforcement Period, then [***] with respect to any sales of Electrode Systems, Cells or Complex Systems to which Licensee commits in connection with that material business opportunity. Licensor in the Response Notice shall identify the jurisdictions identified in the applicable Infringement Notice in which enforcement actions are not possible due to lack of Licensor Licensed Patent Rights covering the Third Party's products. If Licensor, after good faith investigation, determines that enforcement is not legally warranted in a jurisdiction identified, Licensor shall then promptly advise Licensee, who agrees to discuss to determine the appropriate measures to be taken, if any. If Licensor is unable to undertake any enforcement action due to lack of Licensor Licensed Patent Rights in any jurisdiction identified by Licensee, [***] with respect to sales of Electrode Systems, Cells and Complex Systems that are

intended for final use in that jurisdiction. For purposes of this Section 5.4, a "material business opportunity" shall mean a transaction that Licensee reasonably expects, at the time of the Infringement Notice, to result in aggregate revenue of more than [***].

7.1.2 royalties anywhere in the world during any Calendar Quarter between January 1, 2012 and [***], equal to [***] of Net Sales during such Calendar Quarter, with respect to:

a) any Cell, Electrode System, or Complex System sold or Have Sold by Licensee (or Procter & Gamble, as provided in Section 2.4) to a Third Party ("Licensee-Supplied Components"), excluding Cells, Electrode Systems, or Complex Systems supplied to a Joint Venture (1) that were sold by Licensee to the Joint Venture at prices which do not reflect an arms length transaction or (2) for which Licensee chooses not to pay royalties on Net Sales arising from such sale of the applicable Licensee-Supplied Components to such Joint Venture (clauses (1) and (2), collectively and separately, "Excluded JV Sales"); and

b) any Cell, Electrode System, or Complex System sold or Have Sold by a Joint Venture to another Third Party ("JV Products") which incorporate

Cells, Electrode Systems, or Complex Systems that were Excluded JV Sales.

7.1.3 royalties anywhere in the world during any Calendar Quarter starting after [***], equal to the product of the applicable royalty rate specified in Section 7.2 below and [***] of Net Sales during such Calendar Quarter, with respect to:

a) any Cell, Electrode System, or Complex System sold or Have Sold by Licensee (or Procter & Gamble, as provided in Section 2.4) to a Third Party, excluding Excluded JV Sales; and

b) any JV Products sold or Have Sold by a Joint Venture to another Third Party which incorporate Cells, Electrode Systems, or Complex Systems that were Excluded JV Sales.

No royalties shall be payable by Licensee on any Cell, Electrode System, or Complex System sold or Have Sold by Licensee, a Related Corporation, or a Joint Venture to a Third Party anywhere in the world prior to December 31, 2011 inclusively.

7.1.4 For the avoidance of doubt, royalties shall not be due in connection with the transfer of any [***] due to limits placed on Licensee's, Procter & Gamble's, Toll Manufacturers', and Joint Ventures' rights to transfer [***] which require its ultimate inclusion in a Cell, Electrode System, or Complex System that is royalty-bearing under this Agreement.

7.2 Calculation of Applicable Royalty. At any time during each calendar year during the Term starting after [***], the applicable royalty for calculation of Licensor's consideration stated in Article 7.1 shall be determined as follows:

7.2.1 Until Licensee has accrued total royalties owed to Licensor equal to [***] in that calendar year on Net Sales of Cells, Electrode Systems, or Complex Systems that are made during this time frame, the applicable royalty shall be [***] of such Net Sales.

7.2.2 After Licensee has accrued total royalties owed to Licensor greater than [***] in that calendar year but before Licensee has accrued total royalties owed to Licensor equal to [***] in that calendar year on Net Sales of Cells, Electrode Systems, or Complex Systems that are made during this time frame, the applicable royalty shall be [***] of such Net Sales.

7.2.3 After Licensee has accrued total royalties owed to Licensor greater than [***] in that calendar year but before Licensee has accrued total royalties owed to Licensor equal to [***] in that calendar year, on Net Sales of Cells, Electrode Systems, or Complex Systems that are made during this time frame, the applicable royalty shall be [***] of such Net Sales.

7.2.4 After Licensee has accrued total royalties owed to Licensor greater than [***] in that calendar year but before Licensee has accrued total royalties owed to Licensor equal to [***] in that calendar year, on Net Sales of Cells, Electrode Systems, or Complex Systems that are made during this time frame, the applicable royalty shall be [***] of such Net Sales.

7.2.5 After Licensee has accrued total royalties owed to Licensor greater than [***] in that calendar year until the end of that calendar year, on Net Sales of Cells, Electrode Systems, or Complex Systems that are made during this time frame, the applicable royalty shall be [***] of such Net Sales.

7.3 Change in the relative percentage of sale of Cells, Electrode Systems, and Complex Systems. In the event the present relative percentage of Licensee's sales (including all royalty-bearing sales of Related Corporations or Joint Ventures under Section 7.1 and 7.2) of Electrode Systems and Cells, in the aggregate compared to the percentage of Licensee's sales of Complex Systems (including all royalty-bearing sales of Related Corporations or Joint Ventures under Section 7.1 and 7.2), in the aggregate being currently estimated by Licensee to be under [***] for [***] and over [***] for [***], increases substantially so that Licensee's revenue for sales of [***] (including all royalty-bearing sales of Related Corporations or Joint Ventures under Section 7.1 and 7.2) represent more than [***] of Licensee's overall business in Cells, Electrode Systems, and Complex Systems (including all royalty-bearing sales of Related Corporations or Joint Ventures under Section 7.1 and 7.2) within any given period of four consecutive Calendar Quarters, Licensee agrees to promptly notify Licensor and the Parties shall enter into good faith negotiations to determine whether it shall still be appropriate for the royalties applicable on such sales of Electrode Systems, Complex Systems and Cells to be calculated on only [***] of the applicable Net Sales of Licensee or whether such percentage should be raised to account for the increased relative value of the Licensed Product within Licensee's total revenue. The obligations of this Section 7.3 shall survive any Change of Control of A123.

7.4 Change of Control of A123.

7.4.1 In the event a Third Party, which is (A) currently legally engaged in making Licensed Products, including Complex Systems, Cathode Powder, Cells, or Electrode Systems incorporating Licensed Products, or (B) a potential sublicensee with whom Licensor has executed a confidentiality agreement, and which has not entered into a sublicense agreement on Licensor Licensed Patent Rights with Licensor (a "Competitive Acquirer"), acquires the Control of A123, the royalties payable in respect to all sales of Cells, Electrode Systems, and/or Complex Systems taking place after the date of acquisition of Control shall be as provided in Sections 7.1.2, 7.1.3 and 7.2 until the aggregate royalties paid by Licensee (including any royalties paid by Licensee in connection with any JV Products or any Net Sales arising from NET SALES of Procter & Gamble pursuant to Section 2.4) under this Agreement reach [***], at which time royalties payable shall be as provided in Sections 7.1, 7.2 and 7.7 with the exception that royalties on sales of

Complex Systems, Cells and Electrode Systems shall be based on [***] Net Sales of such Complex Systems, Cells and Electrode Systems (instead of [***] Net Sales), subject in all respects to Section 7.14 and 7.15.

7.4.2 In event a Third Party who is not a Competitive Acquirer, acquires Control of A123, the royalties payable in respect to all sales of Cells, Electrode Systems, and/or Complex Systems taking place after the date of acquisition of Control shall be as provided in Sections 7.1 and 7.2.

7.5 Royalty Accrual Date. For purposes of determining the rates for the applicable running royalty on sales of Cells, Electrode Systems, and/or Complex Systems and calculating the correct royalties owed for any calendar year, royalties for a particular sale of Cells, Electrode Systems, and/or Complex Systems shall accrue on the date that the Net Sales of each one of the Cells, Electrode Systems, and/or Complex Systems is invoiced by Licensee.

7.6 Calculation of Quarterly Payments after [***] until [***]. During the calendar years starting respectively on [***], Licensee shall, subject to Section 7.11 below, pay to Licensor the royalties as accrued in each Calendar Quarter following the end of such Calendar Quarter.

7.7 Calculation of Quarterly Payments after [***]. During the calendar year starting on [***], Licensee shall, subject to Section 7.11 below, pay to Licensor the royalties as accrued in each Calendar Quarter following the end of such Calendar Quarter. During each successive calendar year, Licensee shall, subject to Section 7.11 below, pay to Licensor for each Calendar Quarter an estimated royalty for sales of Cells equal to [***] of the product of [***] of the Net Sales of Cells, Electrode Systems and/or Complex Systems made during that Calendar Quarter by the average royalty rate applied on Cells during the prior calendar year.

7.8 Annual True up Payments. Licensee shall also pay to Licensor on the 30th day following the end of each calendar year starting after [***], a true up payment equal to the difference between, on the one hand, the sum of the four quarterly payments of the estimated royalty for Cells, Electrode Systems and/or Complex Systems and, on the other hand, the actual royalties accrued from sales of Cells, Electrode Systems and/or Complex Systems as calculated using the applicable royalties set forth herein. In the case where the sum of the four quarterly payments of the estimated royalty for Cells, Electrode Systems and/or Complex Systems is greater than the actual royalties accrued from sales of Cells, Electrode Systems and/or Complex Systems, the difference shall be credited against royalty payments for the successive calendar year or years as the case may be until such credit is exhausted, or refunded if no further royalties are payable.

7.9 Term of Royalty Payment Obligation. The royalties under this Section 7 are payable during the Term.

7.10 Payment. The royalties calculated pursuant to Sections 7.1.1a) and 7.1.3 and to Sections 7.2.1 to 7.8 shall be paid to Licensor on a Calendar Quarterly basis within thirty (30) days

after the end of each Calendar Quarter during the Term. All amounts payable hereunder by Licensee must be paid in US Dollars without deduction for taxes, assessment, fees or charges of any kind unless expressly allowed herein.

7.11 Interest. Licensee shall pay Licensor interest on any amounts not paid when due. Such interest shall accrue from the fifteenth day after the payment was due, at a rate of twelve percent (12%) per year compounded monthly and the interest payment shall be due and payable on the first day of each month after interest begins to accrue until full payment of all amounts due to Licensor pursuant to this Agreement is made.

7.12 Tax Withholding. To the extent required by law, Licensee may retain from all payments payable to the Licensor hereunder, any required withholding taxes and shall forward such retained payments to the competent tax authorities, provided, however, the following conditions are met: (a) the respective tax is an income tax and not any consumption tax, use tax, sales tax or other tax; (b) Licensor is liable for such taxes under applicable laws; and (c) Licensee is required by applicable laws to withhold the tax from payments due to the Licensor and to forward such tax to the competent tax authorities. If taxes have to be withheld, Licensee shall give notice to that effect to Licensor, without undue delay, at the latest five (5) business days before the payment is made, make the necessary withholding and make timely payment of the amount withheld to the appropriate governmental authority. If the Licensee's entity making a payment under this Agreement will be other than United States tax resident, Licensee shall provide notice of the tax residence of the payer to Licensor at least ninety (90) days before the payment is made.

Licensor shall take such actions as permitted under applicable law to obtain an exemption or reduction of withholding taxes on any payments hereunder. If Licensee is United States tax resident, Licensor shall provide Licensee with the appropriate US-tax forms duly completed and signed (e.g. W8-BEN and/or W8-IMY as the case may be) showing that Licensor is tax-exempt or entitled to a reduction of withholding taxes under applicable tax laws or under the applicable tax treaty provisions.

All taxes so withheld shall be paid before penalties attached thereto or interest accrued thereon. If any such penalties or interest nonetheless become due, Licensee shall make prompt payment thereof to the appropriate governmental authority.

If Licensor becomes liable for, and pays any amounts in respect of taxes on any payment due by Licensee hereunder or in respect of penalties or interests thereon, Licensee shall reimburse Licensor in the currency in which Licensor shall be liable to pay such amount in respect of taxes, penalties or interests.

If Licensor is or becomes entitled under any applicable law or treaty to a reduced withholding rate on amounts payable by Licensee under this Agreement, or a complete exemption from withholding with respect to taxes on amounts payable by Licensee under this Agreement, Licensor shall complete and deliver from time to time to Licensee, as soon as possible after Licensee's request, any form (e.g.. if Licensee is United States tax resident, Forms W8-BEN and/or W8-IMY as the

case may be) that Licensee is required to obtain to give effect to the reduced rate or exemption.

Licensee shall pay forthwith to Licensor any additional amount necessary to ensure that the amount actually received by Licensor from any payment made by Licensee hereunder, after any withholding tax, is equal to the amount that Licensor would have received had no tax amount been required to be withheld on that payment; provided that, if the Licensor is not tax resident in Switzerland, the maximum additional amount the Licensee is required to pay under this Section 7.12 shall be the amount that would have been due if the Licensor had been tax resident in Switzerland.

Licensee and Licensor each represents, warrants and agrees that it will take all necessary steps to obtain the lowest available rate for withholding taxes under all applicable tax treaties and under domestic law. Licensee further represents, warrants and agrees that it will withhold taxes at the lowest rate available under such treaties and domestic law provisions; provided Licensor complies with all applicable requirements for such lowest rate.

Licensee shall issue or provide to Licensor the documents required under applicable law (such as tax assessment notices, proof of payment/bank statements) attesting the withholding tax amounts withheld and remitted by Licensee to the competent tax authorities in connection with any and all payments hereunder. These documents shall be issued or provided without undue delay, at the latest within sixty (60) calendar days following the end of each calendar year.

7.13 Foreign Sales. The conversion of foreign sales and the respective royalty payments into US Dollars shall occur as the sales are invoiced according to Generally Accepted Accounting Principles in the United States. For all royalty payments the conversion ratio from the respective currency to US Dollars shall be based on the applicable exchange rate on the business day of invoicing (or, if such day is not a business day in the United States, on the immediately following business day in the United States) as reflected on Statistical Release H.10 issued by the Board of Governors of the Federal Reserve System for conversion of such currency to US Dollars. The conversion ratio from another currency to the US Dollar for any other payment to Licensor pursuant to this Agreement shall be based upon the arithmetic mean of the exchange rates for each day in the relevant period as reflected on Statistical Release H.10 issued by the Board of Governors of the Federal Reserve System for conversion of such currency to US Dollars.

7.14 Most Favored Licensee. Licensor shall ensure that the terms of this Agreement, taken as a whole, shall be no less favorable than the terms taken as a whole provided to any Third Party licensee of the Licensor Licensed Patent Rights. In the event that a sublicense is granted under the Licensor Licensed Patent Rights for the development, manufacture, use and/or sale of Cathode Powder, Cells, Electrode Systems, and/or Complex Systems on terms that are, taking this Agreement and the proposed Third Party sublicense agreement as a whole, more favorable for such Third Party than the terms of this Agreement as applied to Licensee, then Licensor shall inform License of such agreement within thirty (30) days of entering into such an agreement with any Third Party, and, at Licensee's

option, there shall be imposed an adjustment of the terms of this Agreement on a prospective basis so that Licensee's terms are not materially less favorable than the terms granted to the Third Party sublicense in light of the relevant factors. Unless permitted by the confidentiality terms of the Third Party sublicense agreement, Licensee shall not be entitled to directly review such agreement, but instead may provide the Third Party agreement to an independent auditor selected by Licensee who shall report to Licensee whether the terms, taken as a whole, are more or less favorable than those of this Agreement. Should the auditor conclude that the terms, taken as a whole, are more favorable than those of this Agreement, auditor shall also, upon Licensee's request, identify such terms that together are more favorable to Licensor, who will disclose such terms to Licensee at that time. Upon not less than thirty (30) days advance written notice to Licensor, Licensee is entitled to have an independent appointed auditor have access to such books and records of Licensor as necessary to conduct a review or audit of Licensor's compliance with this Section 7.14. For the avoidance of doubt, the terms of the licenses with Sony Corporation, the terms of the Head License Agreement and the terms of any settlement agreement with a Third Party regarding the Licensor Licensed Patent Rights shall not be taken into consideration under this Section 7.14.

7.15 Notice of Alliance Licenses; Preserving Licensee's Discount from Licensor's Royalty Structure.

7.15.1 Licensor shall provide Licensee with an abstract of the financial terms of each sublicense, or any amendment to a previous sublicense, granted by Licensor on or after the Effective Date, under any of the Licensor Licensed Patent Rights, for the development, manufacture, use and/or sale of Cathode Powder, Cells, Electrode Systems, and/or Complex Systems, excluding those set forth in Section 7.15.6 below. Such abstract need not provide the identity of the parties to the relevant agreement, but shall provide sufficient financial information to enable Licensee to apply the terms of this Section 7.15 to such agreement. Although certain reductions in royalty rates or up-front payments may result from the application of this Section 7.15 involving future licenses governing the sale of Cathode Powder, nothing herein shall be construed to expand the licenses granted in Sections 2.1 and 2.2 with respect to the sale of Cathode Powder by A123.

7.15.2 Licensor acknowledges that Licensee is entering into this Agreement based on an understanding that in general, as of the time of the Effective Date, Licensor licenses the Licensor Licensed Patent Rights to its licensees subject to the Royalty Schedule and the Powder Royalty Schedule (as defined in Section 7.15.3), and subject to a standard up-front, non-creditable license fee payable by such third party licensees of [***] ("Standard Up Front Fee"), effective from the commencement of each of its agreements which sublicense the Licensor Licensed Patent Rights.

7.15.3 If, at any time during the Term, a sublicense is granted to any Third Party by Licensor, under the Licensor Licensed Patent Rights, for the development, manufacture, use and/or sale of Cathode Powder, Cells, Electrode Systems, and/or

Complex Systems, in which the applicable licensee is required to pay any royalty rates ("Lower Rates"), with respect to Cells, Electrode Systems, and/or Complex Systems, less than the royalty rates set forth in the Royalty Schedule (which are [***] as provided in each of Sections 7.2.1 through 7.2.5, respectively) or, with respect to Cathode Powder, less than the royalty rates set forth in the "Powder Royalty Schedule" ([***] at the same royalty amount owed set forth in Sections 7.2.1 through 7.2.5, but as applied to Net Sales of Cathode Powder) (collectively, the "Standard Rates") for any of the same threshold of Net Sales, but with an upfront fee that is not higher than the Standard Up Front Fee, then Licensor shall provide Licensee with written notice describing such Lower Rates, and, prior to [***], the royalty rate of [***] set forth in Section 7.12 shall be reduced by an amount proportional to the proportion of the Lower Rates to the Standard Rates or, subsequent to [***], the Royalty Schedule under this Agreement shall be reduced by an amount to be the same as the Lower Rates or, in the case of Lower Rates applicable to the Powder Royalty Schedule, the rates in the Royalty Schedule shall be reduced by an amount proportional to the proportion of the Lower Rates to the Standard Rates. Any recalculated royalty rates applicable under this Section 7.15.3 will only be applied to sales after the date of any such sublicense granted to a Third Party that results in such recalculated rates. The application of such recalculated rates shall never result in the refund of any amounts accrued prior to the date of any such sublicense granted to a Third Party that results in such recalculated rates.

7.15.4 If, prior to two (2) calendar years from the Effective Date, a sublicense is granted to any Third Party by Licensor, under the Licensor Licensed Patent Rights, for the development, manufacture, use and/or sale of Cathode Powder, Cells, Electrode Systems, and/or Complex Systems or similar products, in which the applicable licensee is required to pay any up front fee (the "Lower Up-Front Fee") that is less than the Standard Up-Front Fee, the total of Five Million U.S. Dollars ($5,000,000) due in Section 7.1 shall be reduced by an amount proportional to the proportion of the Lower Up-Front Fee to the Standard Up-Front Fee. Subsequent to this two-year period, no adjustments to the amount due in Section 7.1.1 shall be made.

7.15.5 Should any reduction under this Section 7.15 in royalties due under this Agreement or in the up-front payment due under Section 7.1.1 result in Licensee having previously paid Licensor an amount in excess of the amount actually due under this Section 7 (an "Overpayment"), Licensor shall hold such Overpayment as credit against future royalties due and shall provide Licensee with an accounting of any Overpayment within four (4) weeks of its establishment. Licensee shall reduce the subsequent royalty payment(s) by the amount of the Overpayment.

7.15.6 The net effect of reduction in royalty rate applicable to Net Sales arising from any application of royalty rates to less than [***] of such other licensee's Net Sales from Cathode Powder, Cells or Electrode Systems, or less than [***] of such

other licensee's Net Sales from Complex Systems, shall be deemed a reduction in the Standard Rates for that license for the purposes of this Section 7.15. For the avoidance of doubt, the terms of [***], the terms of [***] and the terms of [***] regarding the Licensor Licensed Patent Rights shall not be taken into consideration under this Section 7.15. Furthermore, any royalty-free, non-exclusive license to all or part of the Licensor Licensed Patent Rights granted to [***] shall not be taken into consideration under this Section 7.15.

8. REPORTING; BOOKS AND RECORDS.

8.1 Calendar Quarterly Reporting and Payment. Within [***] after the end of each Calendar Quarter, Licensee shall provide Licensor with a true and accurate report on royalties due hereunder for such Calendar Quarter; and during the first Calendar Quarter of each [***] with an [***] report of the royalties that were payable in respect of sales made during the preceding [***]. The royalty report shall identify and report separately:
