§1 Products

1.1 ASPEN agrees to sell and deliver exclusively to BASF and BASF agrees to purchase and receive Products from ASPEN on the terms and conditions of this Agreement for incorporation into value added products and systems for sale to customers making use of the Products within the BASF Markets identified in Annex 1. BASF will not sell or otherwise supply Product to third parties who BASF knows, or reasonably should know, intend to use the Products in any markets other than the BASF Markets. For the sake of clarity, BASF acknowledges that nothing in this Agreement restricts ASPEN’s ability to sell its products other than Products to any third party or within any market anywhere in the world.

1.2 The Products to be delivered shall be in accordance with the Specifications set forth in Annex 1 as of the date of delivery. The Specifications may be modified only upon the mutual written consent of both Parties.

1.3 ASPEN shall inform BASF at least [***], or such shorter period as may be agreed by both Parties in writing, in advance of any changes that recognizably affect the quality of a Product as set forth in the Specifications. In particular, ASPEN shall inform BASF of changes to processes involving the introduction of new technologies, changes to raw materials and transfer of production to another location. Products that are affected by such changes may only be shipped after ASPEN has obtained the written consent of BASF.

1.4 Through the Term, ASPEN may develop Successor Products that would be supplied to BASF subject to the Parties reaching agreement as to revised specifications, pricing, volumes, and related terms.

1.5 In case (i) BASF is not able to profitably meet the requirements of its customers or (ii) alternative product characteristics or specifications are required for BASF to meet legal requirements, in each case, with respect to Products, then BASF will immediately inform ASPEN thereof and provide ASPEN with a description of the specifications and characteristics of new products necessary to meet the requirements of BASF’s customers.

only to the extent that the efforts could be reasonably expected to achieve the desired specifications and characteristics of such enhanced products within a period of [***]. If successfully developed, and on agreement of the Parties as to revised specifications, pricing, volumes, and related terms for such enhanced products as provided in Section 1.4, such enhanced products will be deemed Successor Products. If ASPEN cannot develop such enhanced products within a period of [***], the Parties will consider development of such enhanced products for inclusion as a project under the JDA.

§2 Volumes and Forecasting

2.1 During the Term, ASPEN will sell and deliver to BASF volumes of Product within the Total Volume Range for use in the BASF Markets, pursuant to §2.2 and §2.3.

2.2 During the Pre-Marketing Phase, BASF may elect to purchase Products within the Total Volume Range applicable to each calendar year in its sole discretion. BASF shall provide purchase orders for Product, in volumes, in the aggregate, within the applicable Total Volume Range, for delivery within calendar years [***]. The Parties will within [***] of ASPEN’s receipt of each order develop a mutually agreeable delivery schedule for delivery of such Product consistent with ASPEN’s lead times then in effect.

2.3 On or before [***] and each [***] thereafter, the Target Volume of Product to be purchased by BASF for the following calendar year, which shall be within the applicable Total Volume Range defined in Annex 2, shall be defined and ordered by BASF from ASPEN. The Parties will, within [***] of BASF’s order, develop a mutually agreeable delivery schedule for delivery of Product aggregating to the Total Volume Range in the following calendar year consistent with ASPEN lead times. The purchase and sale of the Target Volume thus ordered for each calendar year shall be binding upon the Parties. BASF orders for Product in volumes in excess of the Target Volume for each calendar year shall be binding on ASPEN only on Aspen’s express written acceptance of such orders.

§3 Safety Stock

3.1 ASPEN will build a Safety Stock of Product on or before [***] equivalent to [***] of the agreed Target Volume (see example in Annex 3) applicable to calendar year [***]. Such Safety Stock will be adjusted on or before [***] of each successive calendar year to [***] of the applicable Target Volume for such calendar year. At BASF’s direction, Safety Stock may be utilized to meet Target Volume in the event of a Force Majeure as defined in Section 7.

3.2 In addition, BASF will be entitled to direct ASPEN to sell and deliver Safety Stock to BASF once in any calendar year in the event that BASF’s requirements for Product exceed Target Volume and ASPEN is unable to meet BASF’s additional requirements. After any delivery and

Page 7 of 30

sale of Products from Safety Stock to BASF, ASPEN will take commercially reasonable efforts to replenish Safety Stock within a six month period. ASPEN shall use commercially reasonable efforts to rotate Safety Stock to reduce aging of such Safety Stock.

§4 Prices and Conditions

4.1 The Price for Product sold hereunder shall be calculated as set forth in the Side Agreement. The terms of this Agreement and the Side Agreement shall be the exclusive terms and conditions with respect to purchase and supply of Products under this Agreement and take precedence over any additional or different terms and conditions provided by either Party, to which notice of objection by the other Party is hereby given. Neither the commencement of performance, delivery nor receipt of products or payment shall be deemed an acceptance of any additional or different terms and conditions. None of the terms and conditions contained herein may be added to, modified, superseded or otherwise altered except in writing by duly authorized representatives of the parties.

4.2 All Prices are in United States dollars. Prices are exclusive of all charges or levies of any nature, including all applicable federal, state, provincial, municipal or other governmental excise, sales, use, value added, occupational, import duties, or similar taxes or tariffs now in force or enacted in the future (collectively, the “Additional Charges”) and, therefore, are subject to an increase in an amount equal to any such Additional Charges that ASPEN may be required to collect or pay upon sale or delivery of Products purchased. A certificate of exemption or similar document in appropriate form for the jurisdiction of BASF’s place of business and any jurisdiction to which Products are to be directly shipped hereunder is required in order to exempt the sale from sales or use tax liability. BASF shall obtain and furnish evidence of such exemption at the time of placement of order. BASF agrees to indemnify and hold harmless ASPEN and its successors and assigns from and against any liability for tax in connection with the sale or use, as well as the collection or withholding thereof, including penalties and interest. ASPEN will provide a certificate of origin with any shipment of Products. ASPEN and BASF will work together to ensure (including providing any reasonable declaration) the transactions pursuant to this Agreement can benefit from the anticipated Transatlantic Trade and Investment Partnership.

4.3 On request of BASF, ASPEN’s books and records as they relate to annual Price calculations may be audited by an independent third party auditor without a prior business relationship with either BASF or ASPEN. Such audit will be to examine whether Price has been calculated by ASPEN in accordance with the provisions of this Agreement in all material respects. ASPEN will make available or provide access to all relevant documents to the third party auditor. The independent auditor will provide a summary report to BASF and ASPEN on whether ASPEN’s Price calculations are consistent in all material respects with the provisions of this

Portions of this Exhibit, indicated by the xxxx “[***],” were omitted and have been filed separately with the

Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential

Agreement. The third party auditor will keep all other information of ASPEN strictly confidential and will not disclose such information to BASF or any other third party. ASPEN shall bear the costs of the third party auditor in the event ASPEN’s Price calculations are not consistent in all material respects with the provisions of this Agreement. Otherwise BASF shall bear such audit costs.

4.4 All orders must be placed in writing and verbal orders shall be confirmed in writing. All orders must include requested delivery dates, quantities, shipment destination and complete description of Products being ordered. After receipt of an order, ASPEN will confirm its acceptance in writing and may also inform BASF of an estimated ship date simultaneously or at a later date. Orders accepted or acknowledged by ASPEN cannot be cancelled without the prior written consent of ASPEN. No order can be cancelled after the order is shipped.

4.5 All Products will be shipped [***] (Incoterms 2010) from ASPEN’s applicable facility in the U.S. to [***] (“Delivery Point”) and further to [***] (“Destination Point” which, if not specified in the relevant order, will be [***]), unless agreed otherwise in writing. All shipping, handling, transportation, and insurance costs incurred following the release of Product from ASPEN’s applicable facility in the U.S. to the Destination Point shall, to the extent paid by ASPEN, be either included as a separate item in the invoice for Products, or separately invoiced and payable by BASF. In no event shall ASPEN be liable for any delay in delivery caused between Delivery Point and Destination Point, nor shall the carrier selected by ASPEN for the transport from Delivery Point to Destination Point be deemed an agent of ASPEN. ASPEN may make partial shipments against an order in its sole discretion. Each such shipment shall constitute a separate sale, and BASF shall pay for the units shipped whether such shipment is in whole or partial fulfilment of an order. Title to Products shall pass to BASF upon delivery of Products at the Delivery Point.

4.6 BASF shall examine the Products as soon as possible after their arrival at the BASF’s facility, and in any event not more than [***] following the Product’s arrival at BASF’s designated facility. BASF shall notify ASPEN in writing (i) with respect to missing Products, immediately upon receipt by reference to the accompanying xxxx of lading, and (ii) with respect to Products that do not conform to applicable specifications or are damaged in transit due to inadequate packaging, within [***]. The Products will be deemed to conform to the applicable specifications despite minor discrepancies that are usual in the trade, and BASF will not be entitled to abatement of the Price for such minor discrepancies. Where the Products are materially non-conforming, the remedies provided in the limited warranty set forth herein shall serve as BASF’s exclusive remedy.

§5 Pre-Payment and Payment Terms

5.1 In order to support ASPEN’s investment in Plant Two, BASF (or its Affiliate) will provide the Pre-Payment to ASPEN in accordance with Annex 4. The Parties agree that a specified portion of the Pre-Payment will be credited as provided in Annex 4 by ASPEN against payment due on sales and deliveries of Product by ASPEN to BASF between October 1, 2018 and the Target Date. If by the Target Date, credits associated with the sale and delivery of Product by ASPEN to BASF have not fully covered the value of the Pre-Payment, BASF shall be entitled to request from ASPEN the repayment of the remainder of the Pre-Payment Balance to BASF as specified in Annex 4 (“BASF Request”). The BASF Request may be executed at any time after the Target Date until the Pre-Payment has been fully repaid by Aspen upon [***] prior written notice and reflecting the current value of the Pre-Payment Balance.

5.2 As collateral for the Pre-Payment, ASPEN will provide BASF with a Security Interest in ASPEN’s assets in accordance with Annex 4.

5.3 ASPEN shall invoice all orders for Product on shipment. BASF shall settle all invoiced amounts due to ASPEN within [***] of the date of the corresponding invoice. On BASF’s instruction, ASPEN will apply an amount (if available) of the Pre-Payment Balance against payment of up to twenty five and three tenths percent (25.3%) of the invoiced Price of Product. BASF shall remit the remainder in cash in United States dollars by wire transfer. Cash payments not received within the prescribed time shall be assessed a finance charge at the annual rate of [***], starting from the invoice date. BASF shall be liable for any costs or expenses incurred by ASPEN in collecting any late payment, including, but not limited to, administrative and personnel costs, collection agency fees and expenses, court costs, and attorney’s fees and expenses.

5.4 To the extent a BASF Affiliate orders and purchases Products pursuant to this Agreement, ASPEN shall send the respective invoice(s) directly to such Affiliate and such BASF Affiliate shall be responsible for payment of such invoices, subject to the partial credit against Pre-Payment Balance as described in § 5.1.

§6 Warranty

6.1 ASPEN warrants to BASF that the Products supplied pursuant to this Agreement are free from defects in workmanship and materials for a period of one (1) year from the date of shipment to BASF. This limited warranty does not apply to fitness for any particular purpose or for use in any application. Since BASF may obtain devices which have the capability of testing whether Product meets the specifications, no claim of any kind with respect to the conformance of Product to the specifications, whether or not based on negligence, warranty, strict liability or any other theory of law, will be greater than the Price of the quantity of nonconforming Product in respect to which such claim is made. The foregoing constitutes BASF’s exclusive remedy and ASPEN’s sole obligation with respect to any such claim. This limited warranty does not extend to any Product that has been damaged or rendered defective (a) as a result of accident, misuse, abuse,

Page 10 of 30

negligence, installation, act of God, disaster, or other external cause, (b) by the use of parts not manufactured or sold by ASPEN, or (c) by modification or service by anyone other than (i) ASPEN or (ii) anyone authorized by ASPEN. ASPEN is not responsible for damage that occurs as a result of (i) BASF’s failure to follow the instructions that accompany the Products or otherwise provided by ASPEN or (ii) by operation outside the usage parameters specified by ASPEN. No credit shall be allowed for repair work performed by BASF or unauthorized parties. BASF shall notify ASPEN of any non-conformance during the warranty period, obtain from ASPEN a return material authorization (“RMA”) for the non-conforming Products, and return the non-conforming Products to ASPEN, freight prepaid, within [***] of receipt of the RMA, with a statement describing in reasonable specificity the non-conformity for which the Products are returned. ASPEN’s exclusive obligation with respect to the non-conforming Products shall be, at ASPEN’s option, to repair or replace any Product determined to be defective. Products that are repaired or replaced hereunder shall be warranted as set forth above for the remainder of the original warranty period or for [***] after the replacement Products are shipped to BASF, whichever is later.

6.2 NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY OR ANY APPLICABLE LAW OR REGULATION, THE FOREGOING IS BASF’S SOLE AND EXCLUSIVE REMEDY FOR BREACH OF WARRANTY BY ASPEN WITH RESPECT TO THE PRODUCTS. ASPEN MAKES NO OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, AND ALL OTHER WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE ARE HEREBY EXCLUDED. IMPLIED WARRANTIES THAT MAY BE IMPOSED BY LAW AND CANNOT BE DISCLAIMED ARE LIMITED IN DURATION TO THE LIMITED WARRANTY PERIOD SET FORTH HEREIN. BASF PURCHASES AND ACCEPTS THE PRODUCTS SOLELY ON THE BASIS OF THE LIMITED WARRANTY EXPRESSED HEREIN. UNDER NO CIRCUMSTANCES SHALL ASPEN BE LIABLE BY VIRTUE OF THIS LIMITED WARRANTY OR OTHERWISE FOR ANY SPECIAL, INDIRECT, SECONDARY, INCIDENTAL OR CONSEQUENTIAL DAMAGES (INCLUDING BUT NOT LIMITED TO LOSS OF PRODUCTION TIME) TO ANY PERSON OR PROPERTY ARISING OUT OF THE USE OR INABILITY TO USE THE PRODUCTS. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THE ABOVE LIMITATION OR EXCLUSION MAY NOT APPLY. THE LIABILITY OF ASPEN HEREUNDER FOR ALL CLAIMS SHALL NOT EXCEED THE SUM OF BASF’S PAYMENTS FOR THE PRODUCTS THAT ARE THE SUBJECT OF DISPUTE. EXCEPT IN CONNECTION WITH AN AUTHORIZED SALE, FOR ANY PRODUCTS THAT ARE DIVERTED FROM ASPEN’S INTENDED COUNTRY OF DESTINATION TO ANOTHER COUNTRY OR JURISDICTION, THE WARRANTY IS HEREBY VOIDED.

7.2 If a Force Majeure event occurs, the Party affected shall inform the other Party as soon as practical indicating the expected duration and extent of such contingency. Moreover, the affected Party shall promptly take commercially reasonable efforts to settle such contingencies so that the performance of the obligations under this Agreement can be resumed as soon as possible.

§8 Good Faith

8.1 Both Parties recognise that they cannot anticipate all future technical and economic developments that could affect the rights, obligations and commitments contemplated herein. Therefore, ASPEN and BASF agree to cooperate and work with one another in good faith during the Term, taking into account any and all unanticipated developments and occurrences to minimise any undesired impact on the intent of this Agreement.

Therefore, BASF Affiliates shall be entitled to order Product from ASPEN or ASPEN’s Affiliates in their own name and on their own account at the terms laid down in this Agreement. In case BASF and BASF Affiliates have placed orders pursuant to the terms and conditions of this Agreement, the Target Volumes set out in Section 2 shall be fulfilled to the extent of the quantity invoiced to BASF and the respective BASF Affiliates.

Annex 4 – Pre-Payment and Security Interest

Pre-Payment

1. BASF will remit to ASPEN by wire transfer in eight equal consecutive quarterly installments a Pre-Payment amount in the aggregate of twenty two million U.S. Dollars ($22,000,000) as set forth in this Annex 4.

2. The obligation of BASF to make the Pre-Payment as set forth above is conditioned upon (i) the security interest as described in this Annex 4 being effective, (ii) ASPEN’s board of directors having approved the construction of Plant Two, (iii) ASPEN having received a commitment from a third party lender for a term loan or revolving line of credit of at least $30 million, and (iv) pursuant to Section 1.2 of the Supply Agreement, the Parties having agreed to final specification values for Products reasonably reflecting, as of the Effective Date, Products’ current characteristics, ASPEN’s current manufacturing capability and the yield levels assumed in arriving at [***] Cost for [***]. Parties acknowledge that an agreement on final values for certain Product characteristics (including shear strength, compressive strength and long and short term water absorption) is not a condition to BASF’s obligation to make the Pre-Payment. While the parties anticipate that the obligation of BASF to make the Pre-Payment will commence on October 1, 2016, the obligation to make the Pre-Payment will commence on the later of (a) October 1, 2016, or (b) the first day of the calendar quarter following that in which all of the conditions described in this Section 2 have been satisfied, if such date is later than September 30, 2016.

3. On or before the first day of the calendar quarter in which the first payment of the Pre-Payment amount is due, ASPEN shall provide to BASF, on a confidential basis, the projected date of completion of construction of Plant Two at the time of approval of ASPEN’s board of directors. Thereafter, on or before the first day of each calendar quarter in which a portion of the Pre-Payment is due, ASPEN shall provide to BASF a statement of ASPEN’s good faith projection of the date of completion of construction of Plant Two along with a summary report of amounts expended on the Plant Two project at that time. Should the projected date of completion of construction encounter delays of three months or more in any material respect, for each month of such delay, BASF’s obligation to make its next quarterly payment shall be postponed by a commensurate number of months.

4. After October 1, 2018, on BASF’s instruction, ASPEN will credit up to twenty five and three tenths percent (25.3%) of any amounts invoiced by ASPEN for Product sold and delivered to BASF pursuant to this Agreement against the available Pre-Payment Balance, if any.

5. Upon BASF Request pursuant to §5.1, the Pre-Payment Balance, if any, will be refunded by ASPEN by wire transfer to BASF in four equal quarterly installments.

6. The Pre-Payment Balance may be repaid by ASPEN to BASF at any time in whole or in part and for any reason. The Pre-Payment Balance will not bear interest.

7. Should the schedule for construction of Plant Two be delayed by more than six months, the Parties will reasonably re-negotiate dates, prices and volume commitments established in this Agreement to reflect the revised schedule in a manner substantially preserving the intent of the parties as of the Effective Date.

• A first priority leasehold mortgage on all of ASPEN’s rights under the lease between ASPEN and the Authority by which ASPEN leases the real estate and buildings constituting the Georgia Plant, including a consent from the Authority which would allow BASF to become the lessee under the lease in the event of a default by ASPEN in its obligation to repay the Payment Balance to BASF;

• A first priority security interest in all of ASPEN’s rights under any lease between Aspen and the Authority by which the Authority leases machinery and equipment to ASPEN that is located at the Georgia Plant, including a consent from the Authority which would allow BASF to become the lessee under the lease in the event of a default by ASPEN in its obligation to repay the Payment Balance to BASF; and

• A first priority security interest in ASPEN’s right to exercise an option to purchase from the Authority the real property constituting the Georgia Plant and the machinery and equipment leased from the Authority which is located at the Georgia Plant, including a consent from the Authority which recognizes BASF’s rights to exercise the option instead of ASPEN. Upon exercise, the purchase price is a nominal $10.

• Supply agreement for Aspen Aerogel’s Spaceloft^® A2 insulation product initially targeting the global building materials market

• Partnership supports capacity expansion at Aspen Aerogels’ planned Statesboro, GA manufacturing plant

• Joint development agreement for next generation aerogel products to accelerate market expansion

LUDWIGSHAFEN, GERMANY and NORTHBOROUGH, MA, June XX, 2016—BASF SE (“BASF”) and Aspen Aerogels, Inc. (“Aspen”) (NYSE: ASPN) announced today the expansion of their strategic partnership with the signing of an exclusive supply agreement and a joint development agreement. The agreements are designed to increase market penetration, enhance product profitability and facilitate the development of next generation materials.

As part of the supply agreement, Aspen will commit to the exclusive supply of its Spaceloft^® A2 product for incorporation within BASF’s aerogel enhanced Slentex™ wall system for the building materials market. In turn, BASF will invest in the construction of Aspen’s new manufacturing plant and BASF will become a base load customer for Aspen’s capacity expansion. In addition, BASF will provide technical support to Aspen targeting manufacturing productivity, product cost and profit margins.

Initially, the supply agreement will support BASF’s efforts to drive growth in the global building materials market of its Slentex™ wall system incorporating Aspen’s patented technology. BASF may also directly sell or incorporate Spaceloft^® A2 into other systems for applications in certain building, transportation, consumer and industrial markets worldwide. The agreement will run through 2027.

“We chose to partner with Aspen because of their superior aerogel technology platform, which we can enhance as partners in various ways,” said Xxxxxx Xxxx, President of BASF’s Performance Materials division. “The new agreements will accelerate adoption of aerogel technology as an eco-efficient insulation material globally.”

The Joint Development Agreement establishes a framework to develop new aerogel products and technologies. The agreement will give BASF targeted access to Aspen’s world leading technology platform while Aspen will gain access to BASF’s technical expertise, sales channels and financial resources. The partnership will both further Aspen’s market diversification and growth strategy and support BASF’s objective to provide innovative solutions to meet current and future customer needs.

“BASF has played an important role in our development as a company and this next phase of our relationship will support us technically, commercially and financially and will accelerate our diversification into the building materials market,” said Xxx Xxxxx, President and CEO of Aspen. “As our track record in the energy infrastructure and subsea markets has demonstrated, our preferred model is to partner with industry leaders to benefit from their technical, commercial, and financial resources. BASF is a world class company dedicated to promoting energy efficiency by delivering next generation products to the global marketplace. For these reasons, BASF is a perfect partner for Aspen Aerogels.”

The origin of the partnership dates to 2010 when BASF Venture Capital made an equity investment in Aspen and the two companies began to explore technology development and commercialization opportunities within the building materials market. This work led to the development of Aspen’s Spaceloft^® A2 insulation product.
