5. Prosecution; Infringement.

5.1 Appointment and Cooperation. With respect to the rights and activities of ESLR1 set forth in this Section 5, TISICS hereby appoints ESLR1 as its agent for such purposes with the authority to act on TISICS’ behalf with respect to the TISICS IP relating to the PV Field. TISICS shall cooperate with ESLR1 in the exercise of ESLR1’s authority granted herein, and shall execute such documents and take such additional action as ESLR1 may reasonably request in connection therewith.

5.2 Patent Prosecution and Maintenance.

(a) By TISICS. TISICS shall, at its sole cost, be solely responsible for and make all decisions with respect to the preparation, prosecution (including any interferences, oppositions, reissue proceedings and reexaminations) and maintenance of the TISICS Patents. TISICS shall provide to ESLR1 copies of any papers relating to the filing, prosecution or maintenance of TISICS Patents within the PV Field promptly upon receipt and shall provide ESLR1 with a reasonable opportunity to review and comment on such papers with respect to applications within the PV Field.

(b) By ESLR1. TISICS shall not knowingly permit any of the TISICS Patents within the PV Field to be abandoned in any country without ESLR1 first being given an opportunity to assume full responsibility for the continued prosecution and maintenance of same. In the event that TISICS decides not to continue the prosecution or maintenance of any TISICS Patent within the PV Field in any country, TISICS shall provide ESLR1 with notice of this decision at least [****] days prior to any pending lapse or abandonment thereof. In the event that ESLR1 elects to assume responsibility for such prosecution and maintenance within [****] days of TISICS’ notice, Section 5.2(a) shall thereafter apply to such TISICS Patent(s) except that the role of TISICS and ESLR1 shall be reversed thereunder (including that ESLR1 shall be solely responsible for all costs arising from those activities). Such TISICS Patent(s) shall otherwise continue to be subject to all of the terms and conditions of the Agreement in the same way as the other TISICS Patents within the PV Field.

5.3 Enforcement of TISICS IP.

(a) Notice of Infringement. In the event that either Party becomes aware of a suspected infringement or misappropriation of the subject matter of any TISICS IP in the PV Field, or any such TISICS IP is challenged in any action or proceeding (other than any patent interferences, oppositions, reissue proceedings or reexaminations, which are addressed in Section 5.2), such Party shall notify the other Party promptly, and following such notification, the Parties shall confer.

(b) Enforcement. In the case of infringement or misappropriation of the TISICS IP in the PV Field, ESLR1 shall have the right, but not the obligation, to initiate and prosecute such legal action or proceeding or to control the defense of any action or proceeding relating to the ESLR1 IP (other than any patent interferences, oppositions, reissue proceedings or reexaminations, which are addressed in Section 5.2), in its own discretion and at its own expense. If ESLR1 fails to take steps reasonable under the circumstances to resolve such actual or suspected infringement or misappropriation or initiate a lawsuit within [****] days of receiving written notice of such actual or suspected infringement or misappropriation from TISICS or delivering written notice of such actual or suspected infringement to TISICS, as applicable, TISICS shall have the right, but not the obligation, to initiate an action or proceeding, in its own discretion and at its own expense.

(c) Withdrawal. If either Party brings an action or proceeding under this Section 5.3 and subsequently ceases to pursue or withdraws from such action or proceeding, it shall promptly notify the other Party and the other Party may substitute itself for the withdrawing Party under the terms of this Section 5.3.

(d) Recovery Allocation. In the event that either Party exercises the rights conferred in this Section 5.3 and recovers any damages or other sums in such action or proceeding or in settlement thereof, such damages or other sums recovered shall first be applied to all out-of-pocket costs and expenses incurred by the Parties in connection therewith (including attorneys’ fees), unless not reimbursable hereunder. If such recovery is insufficient to cover all such costs and expenses of both Parties, the controlling Party’s costs shall be paid in full first before any of the other Party’s costs. If after such reimbursement any funds shall remain from such damages or other sums recovered, such funds shall be retained by the Party that controlled the action or proceeding under this Section 5.3.

6. Confidentiality.

6.1 Definition of Confidential Information. “Confidential Information” means, subject to the exceptions set forth below in Section 6.2, any information or data, regardless of whether it is in tangible form, of a Party (the “Disclosing Party”) that the Disclosing Party has either marked as confidential or proprietary, or has identified in writing as confidential or proprietary within thirty (30) days of disclosure to the other Party (the “Receiving Party”), and has provided to the Receiving Party under this Agreement; provided that any Disclosing Party’s business plans, strategies, Technology, customers, customer lists, billing records and products shall be deemed Confidential Information of the Disclosing Party even if not so marked or identified and the terms of this Agreement will be deemed Confidential Information. For the avoidance of doubt, any trade secrets contained within the TISICS IP with application in the PV Field shall be deemed the Confidential Information of both Parties, subject to the provisions of this Section 6.

6.2 Exceptions. The obligations in Section 6.1 shall not apply with respect to any portion of the Confidential Information that the Receiving Party can show by competent proof: (i) is publicly disclosed by the Disclosing Party, either before or after it is disclosed to the Receiving Party hereunder; (ii) was known to the Receiving Party or any of its Affiliates, without any obligation to keep it confidential or any restriction on its use, prior to disclosure by the Disclosing Party; (iii) is subsequently disclosed to the Receiving Party or any of its Affiliates by a Third Party lawfully in possession thereof and without any obligation to keep it confidential or any restriction on its use; (iv) is published by a Third Party or otherwise becomes publicly available or enters the public domain, either before or after it is disclosed to the Receiving Party; or (v) has been independently developed by employees or contractors of the Receiving Party or any of its Affiliates without the aid, application or use of Confidential Information of the Disclosing Party.

6.3 Confidentiality Obligations. Except as expressly provided herein, each of the Parties agrees that, for itself and its Affiliates, and for as long as this Agreement is in effect and thereafter, a Party and its Affiliates (the “Receiving Party”) receiving Confidential Information of the other Party or its Affiliates (the “Disclosing Party”) shall not (i) use any such Confidential Information in any way, for its own account or the account of any Third Party, except for the

exercise of its rights and performance of its obligations under this Agreement, or (ii) disclose any such Confidential Information to any party, other than furnishing such Confidential Information to (a) its employees and consultants who are required to have access to the Confidential Information in connection with the exercise of its rights and performance of its obligations under this Agreement, (b) investors, prospective acquirers and professional advisers and (c) ESLR1 Sublicensees and TISICS Sublicensees; provided that such employees and consultants, investors, prospective acquirers and professional advisers and ESLR1 Sublicensees and TISICS Sublicensees are bound by written agreements or, in the case of professional advisers, ethical duties respecting such Confidential Information in accordance with the terms of this Section 6. The Receiving Party agrees that it will not allow any unauthorized Person access to such Confidential Information, and that the Receiving Party will use reasonable measures to protect the confidentiality of such Confidential Information, including implementing and enforcing procedures to minimize the possibility of unauthorized use or copying of such Confidential Information. In the event that the Receiving Party is required by law to make any disclosure of any of such Confidential Information, by subpoena, judicial or administrative order or otherwise, the Receiving Party shall first give written notice of such requirement to the Disclosing Party, and shall permit the Disclosing Party to intervene in any relevant proceedings to protect its interests in such Confidential Information, and provide reasonable cooperation and assistance to the Disclosing Party in seeking to obtain such protection. Notwithstanding the foregoing, ESLR1 and ESLR1 Sublicensees may make such disclosures of Technology covered by the TISICS IP specifically concerning SiC Fiber and relating to the PV Field as any of them may deem reasonably necessary for the purpose of Exploiting the SiC Fiber in the PV Field.

6.4 Terms of this Agreement; Publicity. The Parties agree that the terms of this Agreement shall be treated as Confidential Information of both Parties, and thus may be disclosed only as permitted by Section 6.3.

Subject to the foregoing, neither Party shall make any public announcements relating to the terms, conditions or existence of this Agreement without the prior written consent of the other Party.

6.5 Return of Confidential Information. The Receiving Party agrees that, upon the termination of this Agreement, the Receiving Party will immediately return all Confidential Information of the Disclosing Party and any tangible expression thereof (including all copies, summaries and notes of the contents or parts thereof) to the Disclosing Party and no part thereof shall be retained by the Receiving Party in any form and/or for any reason; provided that the Receiving Party may retain one copy of such Confidential Information for archival purposes to satisfy the Receiving Party’s obligations under any applicable laws. Notwithstanding the foregoing, ESLR1 shall not be obligated to return any Confidential Information of TISICS that is in whole or in part the subject of the license grant set forth in Section 2.1(a), the license granted to ESLR1 in the Composite Field License Agreement or the license granted to ESLR1 in the Other Fields License Agreement, in each case, only for so long as such license is effective.

9.2 ESLR1 Indemnity. ESLR1 on its own behalf and on behalf of its successors, executors, administrators, estate, heirs and assigns, hereby agrees to indemnify, defend and hold TISICS, and each of its Affiliates and direct and indirect partners and members, stockholders, directors, officers, employees and agents and each person who controls any of them within the meaning of Section 15 of the Securities Act or 1933, as amended, or Section 20 of the Exchange Act of 1934, as amended, (each a “TISICS Indemnitee,” and collectively, the “TISICS Indemnitees”) harmless from and against all Losses, arising from (i) any Third Party claim that any use of any Technology embodying the TISICS IP (excluding Joint IP) not in accordance with this Agreement or alteration of any such Technology, in each case, by any of ESLR1 or ESLR1 Sublicensees infringes on, constitutes a misappropriation of the subject matter of, or otherwise violates any Third Party IP, solely to the extent that such Loss would not have arisen but for such alteration or improper or unauthorized use, (ii) any breach or alleged breach of any of the representations or warranties of ESLR1 set forth in Section 7 or (iii) the gross negligence, recklessness or willful misconduct of ESLR1 or ESLR1 Sublicensees.

9.3 The ESLR1 Indemnitees and the TISICS Indemnitees are together referred to in the remainder of this section 9 as “the Indemnitees” and ESLR1 and TISICS each as an “Indemnifying Party” as the context requires.

9.4 Notice of Loss. An Indemnitee shall give the Indemnifying Party notice of any matter which an Indemnitee has determined has given or could give rise to a right of indemnification under this Agreement, within 60 days of such determination, stating the amount of the Loss, if known, and method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises.

9.5 Third Party Claims. If an Indemnitee shall receive notice of any action, audit, demand or assessment (each, a “Third Party Claim”) against it or which may give rise to a claim for Loss under this Section 9, within [****] days of the receipt of such notice, the Indemnitee shall give the Indemnifying Party notice of such Third Party Claim; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations

under this Section 9 except to the extent that the Indemnifying Party is materially prejudiced by such failure. Subject to the following sentence, the Indemnifying Party may assume control of the defense of any Third Party Claim provided that (i) the Indemnifying Party shall (within [****] business days of notice from Indemnitee) deliver to the Indemnitee an unconditional written agreement to defend, and satisfy if the defense is unsuccessful, such Third Party Claim at the Indemnifying Party’s sole cost and expense and (ii) the Indemnifying Party provides adequate assurances that it is financially capable for providing indemnification for such Third Party Claim; provided, however, in any defense assumed by it, the Indemnifying Party will promptly engage qualified reputable attorneys, who shall be subject to the reasonable approval of the Indemnitee; and provided, further, if at any time the Indemnitee determines that it is in its best interests to assume and control the defense of such Third Party Claim, the Indemnitee shall be entitled to assume and control such defense (without limiting the Indemnifying Party’s other indemnification obligations hereunder). Notwithstanding the foregoing, if there exists a conflict of interest that would make it inappropriate for the same counsel to represent both the Indemnitee and the Indemnifying Party as determined in the reasonable judgment of the Indemnitee, then the Indemnitee shall be entitled to retain its own counsel in each jurisdiction for which the Indemnitee determines counsel is required, at the expense of the Indemnifying Party. In the event that the Indemnifying Party exercises the right to undertake any such defense against any such Third Party Claim as provided above, the Indemnitee shall cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party, at the Indemnifying Party’s expense, all witnesses, pertinent records, materials and information in the Indemnitee’s possession or under the Indemnitee’s control relating thereto as is reasonably required by the Indemnifying Party. Similarly, in the event the Indemnitee is, directly or indirectly, conducting the defense against any such Third Party Claim, the Indemnifying Party shall cooperate with the Indemnitee in such defense and make available to the Indemnitee, at the Indemnifying Party’s expense, all such witnesses, records, materials and information in its possession or under its control relating thereto as is reasonably required by the Indemnitee. No such Third Party Claim may be settled by the Indemnifying Party without the prior written consent of the Indemnitee unless the settlement contains a full and complete release of the Indemnitee and does not impose any equitable relief or any other restriction or condition on any of them.

9.6 Indemnification Procedure. If (and to the extent) an Indemnifying Party is responsible pursuant hereto to indemnify an Indemnitee in respect to Third Party Claims, then within ten days after the occurrence of a final determination, finding, order, and/or judgment (a “Final Determination”) (or sooner if required by such determination), the Indemnifying Party shall pay the Indemnitee , in immediately available funds denominated in US Dollars, the amount of any Losses (or such portion thereof as the Indemnifying Party shall be responsible for pursuant to the provisions hereof). In the event that any Losses incurred by the Indemnitee do not involve payment by the Indemnitee of a Third Party claim, then, if (and to the extent) the Indemnifying Party is responsible pursuant hereto to indemnify the Indemnitee against such Losses, the Indemnifying Party shall within ten days after agreement on the amount of the Losses, or the occurrence of a Final Determination of such amount, pay to the Indemnitee, in immediately available funds the amount of such Losses (or such portion thereof as the Indemnifying Party shall be responsible for pursuant to the provisions hereof).

9.7 Cost Offsets. Each of ESLR1 or TISICS as an Indemnitee shall have the right to reduce any payments owed by it to the other under any written agreement between ESLR1 and TISICS by the amount of any indemnifiable Losses suffered by any such Indemnitee (including investigation, defense, settlement or judgment satisfaction and all professional fees).

10. Term; Termination.

10.1 Term. This Agreement shall commence as of the Effective Date and, unless sooner terminated in accordance with the terms hereof or by mutual written consent, shall continue until the later of the end of Period 6 or [****] (as defined in Exhibit D) (the “Term”).

In the event an Abandonment of Construction of ESLR1 Facilities (as defined below) occurs prior to the completion of the initial construction of manufacturing facilities for the Exploitation of SiC Fiber owned or controlled by ESLR1, TISICS may terminate this Agreement immediately upon written notice to ESLR1. “Abandonment of Construction of ESLR1 Facilities” means ESLR1’s failure, manifested over a period of [****] or more consecutive days during the Term, to use reasonable efforts to perform activities relating to the design, construction and/or development of manufacturing facilities for the Exploitation of SiC Fiber, excluding any failure due to (i) a breach by TISICS of its obligations under this Agreement or the Facilities and Start Up Agreement or (ii) causes beyond ESLR1’s reasonable control, such as any of the following events (each, a “Force Majeure Event”): (A) any fire, explosion, unusually severe weather, natural disaster or Act of God; (B) epidemic; any nuclear, biological, chemical, or similar attack; any other public health or safety emergency; any act of terrorism; and any action reasonably taken in response to any of the foregoing; (C) any act of declared or undeclared war or of a public enemy, or any riot or insurrection; (D) damage to machinery or equipment; any disruption in transportation, communications, electric power or other utilities, or other vital infrastructure; or any means of disrupting or damaging internet or other computer networks or facilities; (E) any strike, lockout or other labor dispute or action; or (F) any action taken in response to any of the foregoing events by any civil or military authority. In the event that ESLR1 ceases to manufacture SiC Fiber for use within the PV Field for more than a period of [****] consecutive months following completion of the initial construction of the SiC Facilities, TISICS may terminate this Agreement immediately upon written notice to ESLR1, except if such cessation is due to (1) a breach by TISICS of its obligations under this Agreement or the Facilities and Start Up Agreement or (2) causes beyond ESLR1’s reasonable control, such as a Force Majeure Event.

10.3 Termination Damages. Without prejudice to any other remedies either Party may expressly have hereunder in respect of any breach of this Agreement, neither Party shall be liable

to the other for damages by solely reason of the termination or cancellation of this Agreement in accordance with the provisions set forth above.

10.4 Continuing Obligations. The following shall survive the expiration or termination hereof: (i) the obligation of ESLR1 to pay any accrued, but unpaid, payments due to TISICS hereunder (subject to Section 4.4), (ii) the obligation of TISICS to pay any accrued, but unpaid, taxes, duties, and other levies (if any) applied by any government authority on payments made by ESLR1 to TISICS hereunder (in accordance with Section 4.3(a)), and (iii) the provisions of this Section 10.4, Sections 1 (and any other definitions contained herein), 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 3.1(b), 3.1(e), 3.3, 3.4, 4.2(c), 4.3, 4.4, 5, 6, 7, 8, 9, 10.3, 10.5 and 11 and the last sentence of Section 3.1, provided that, subject to Section 4.4, if TISICS terminates this Agreement for Abandonment of Construction of ESLR1 Facilities, the provisions of Section 2.1 shall not survive such termination except as otherwise set forth in Section 10.5.

10.5 Inventory Sell-Down Period. Without limiting Section 4.4, upon any termination of this Agreement pursuant to Section 10.2(b), ESLR1 may continue to distribute its then-current inventory of SiC Fiber and manufacture and distribute any inventory of SiC Fiber for orders then-confirmed by ESLR1. During this period, the provisions of this Agreement shall continue in force to the extent required for the limited purpose of permitting ESLR1 to distribute its inventory of SiC Fiber in accordance with the foregoing.

11.1 Fees and Expenses. The Parties shall pay all of their own costs, fees and expenses incurred in connection with this Agreement and the consummation (or the preparation for the consummation) of the transactions contemplated hereby (including fees and expenses of legal counsel, accountants and other representatives and consultants and advisors and due diligence (including travel-related) costs, fees and expenses).

11.2 Remedies. Each Party acknowledges and agrees that the other Party would be damaged irreparably in the event any of the provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached. Accordingly, each Party agrees that the other Party shall be entitled to an injunction or injunctions to prevent breaches of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions hereof in any action instituted in any court of the United States or any state thereof having jurisdiction over the Parties and the matter.

11.6 Governing Law; Venue. All issues and questions concerning the construction, validity, enforcement and interpretation of this Agreement (including the Exhibits and Schedules hereto) shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware. In furtherance of the foregoing, the internal law of the State of Delaware shall control the interpretation and construction of this Agreement (including the Exhibits and Schedules hereto), even though under that jurisdiction’s choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily apply. Any and all disputes between the Parties which may arise pursuant to this Agreement will be heard and determined before an appropriate federal court located in Boston, Massachusetts. The Parties hereto acknowledge that such court has the jurisdiction to interpret and enforce the provisions of this Agreement and the parties waive any and all objections that they may have as to personal jurisdiction or venue in the above courts.

11.7 Assignment and Benefit.

(a) ESLR1 may not assign this Agreement without the prior written consent of TISICS to any Third Party, which consent will not be unreasonably withheld, except that ESLR1 may assign this Agreement in whole without the prior written consent of TISICS to any Third Party, including a TISICS Competitor or any Affiliate of a TISICS Competitor, if such Third Party succeeds to all or substantially all the assets and business of ESLR1 or Evergreen by merger or purchase.

(b) TISICS may not assign this Agreement without the prior written consent of ESLR1 to any Third Party, which consent will not be unreasonably withheld, except that TISICS may assign this Agreement in whole without the prior written consent of ESLR1 to any Third Party, including a ESLR1 Competitor or any Affiliate of a ESLR1 Competitor, if such Third Party succeeds to all or substantially all the assets and business of TISICS by merger or purchase.

(c) Any attempted assignment, delegation or transfer by an assigning Party in violation hereof shall be null and void. Subject to the foregoing, this Agreement shall be binding on the Parties and their successors and assigns.

11.8 Consequences of Bankruptcy. All licenses and rights of granted under or pursuant to this Agreement shall be deemed to be, for the purposes of Section 365(n) of the United States Bankruptcy Code (the “Bankruptcy Code”), licenses to rights in “intellectual property” as defined under the Bankruptcy Code.

11.9 Successors and Assigns; Third-Party Beneficiaries. Except as provided herein to the contrary, this Agreement and all of the covenants and agreements contained herein and rights, interests or obligations hereunder, by or on behalf of any of the Parties hereto, shall bind and inure to the benefit of the respective successors and assigns of the Parties hereto whether so expressed or not. This Agreement is for the sole benefit of the Parties and their permitted successors and assigns and nothing herein expressed or implied shall give or be construed to give any non-Party any rights, benefits or claims hereunder; provided, however, that each Indemnitee is intended to be, and is expressly made, a third party beneficiary of this Agreement, entitled to enforce its rights under Section 9 in its own name.

11.10 Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable Law, but if any provision of this Agreement or the application of any such provision to any Person or circumstance shall be held to be prohibited by, illegal or unenforceable under applicable Law in any respect by a court of competent jurisdiction, such provision shall be ineffective only to the extent of such prohibition or illegality or unenforceability, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

11.11 Counterparts. This Agreement may be executed simultaneously in counterparts (including by means of telecopied signature pages), any one of which need not contain the signatures of more than one Party, but all such counterparts taken together shall constitute one and the same Agreement.

11.12 No Waiver. Failure by either Party to enforce any provision of this Agreement shall not be deemed a waiver of future enforcement of that or any other provision.

11.13 Descriptive Headings; Interpretation. The headings and captions used in this Agreement and the table of contents to this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Any capitalized terms used in any Schedule or Exhibit attached hereto and not otherwise defined therein shall have the meanings set forth in this Agreement. The use of the word “including” herein shall mean “including without limitation.” The Parties intend that each representation, warranty and covenant contained herein shall have independent significance. If any Party has breached any representation, warranty or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which the Party has not breached shall not detract from or mitigate the fact that the Party is in breach of the first representation, warranty or covenant.

11.14 Entire Agreement. This Agreement and the agreements and documents referred to herein contain the entire agreement and understanding between the Parties with respect to the subject matter hereof and supersede all prior agreements and understandings, whether written or oral, relating to such subject matter in any way.

11.15 Exhibits and Schedules. All Exhibits and Schedules attached hereto or referred to herein are hereby incorporated in and made a part of this Agreement as if set forth in full herein.

11.16 No Strict Construction. The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties, and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement.
