amendment or supplement thereto, (B) Blue Sky application or other document prepared or executed by the Company (or based upon any written information furnished by the Company) specifically for the purpose of qualifying any or all of the Notes under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”), or (C) materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Notes (“Marketing Materials”), including any road show or investor presentations made to investors by the Company (whether in person or electronically) or (ii) the omission or alleged omission to state in any Free Writing Offering Document, the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum, or in any amendment or supplement thereto, or in any Blue Sky Application or in any Marketing Materials, any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and shall reimburse the Initial Purchaser and each such affiliate, director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by the Initial Purchaser, affiliate, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Offering Memorandum, the Pricing Disclosure Package or Offering Memorandum, or in any such amendment or supplement thereto, or in any Blue Sky Application or in any Marketing Materials, in reliance upon and in conformity with written information concerning the Initial Purchaser furnished to the Company through the Initial Purchaser by or on behalf of the Initial Purchaser specifically for inclusion therein, which information consists solely of the information specified in Section 8(e). The foregoing indemnity agreement is in addition to any liability that the Company may otherwise have to the Initial Purchaser or to any affiliate, director, officer, employee or controlling person of the Initial Purchaser.

(b)    The Initial Purchaser hereby agrees to indemnify and hold harmless the Company, its officers and employees, each of its directors, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any (A) Free Writing Offering Document, Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto, (B) Blue Sky Application, or (C) Marketing Materials, or (ii) the omission or alleged omission to state in any Free Writing Offering Document, Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum, or in any amendment or supplement thereto, or in any Blue Sky Application or in any Marketing Materials any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning the Initial Purchaser furnished to the Company

through the Initial Purchaser by or on behalf of the Initial Purchaser specifically for inclusion therein, which information is limited to the information set forth in Section 8(e). The foregoing indemnity agreement is in addition to any liability that the Initial Purchaser may otherwise have to the Company or any such director, officer, employee or controlling person.

(c)    Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under paragraphs (a) or (b) above except to the extent it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure and; provided, further, that the failure to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to an indemnified party otherwise than under paragraphs (a) or (b) above. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 8, if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its directors, officers, employees and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the indemnified party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. No indemnifying party shall (x) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include a statement as to, or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party, or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there

be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 8(a) or 8(b) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement.

(d)    If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company, on the one hand, and the Initial Purchaser, on the other, from the offering of the Notes, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Initial Purchaser, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Initial Purchaser, on the other hand, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Notes purchased under this Agreement (before deducting expenses) received by the Company, on the one hand, and the total discounts and commissions received by the Initial Purchaser with respect to the Notes purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Notes under this Agreement as set forth on the cover page of the Offering Memorandum. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company, or the Initial Purchaser, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Initial Purchaser agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by any method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), the Initial Purchaser shall not be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by the Initial Purchaser with respect to the offering of the Notes exceeds the amount of any damages that the Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person

guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e)    The Initial Purchaser confirms and the Company acknowledges and agrees that the statements with respect to the offering of the Notes by the Initial Purchaser set forth in the sixth paragraph of the section entitled “Plan of Distribution” in the Pricing Disclosure Package and the Offering Memorandum are correct and constitute the only information concerning such Initial Purchaser furnished in writing to the Company by or on behalf of the Initial Purchaser specifically for inclusion in the Preliminary Offering Memorandum, the Pricing Disclosure Package and the Offering Memorandum or in any amendment or supplement thereto or in any Blue Sky Application or in any Marketing Materials.

9.    Termination. The obligations of the Initial Purchaser hereunder may be terminated by the Initial Purchaser by notice given to and received by the Company prior to delivery of and payment for the Notes if, prior to that time, any of the events described in Sections 7(g) or 7(k)) shall have occurred or if the Initial Purchaser shall decline to purchase the Notes for any reason permitted under this Agreement.

10.    Reimbursement of Initial Purchaser’s Expenses. If (a) the Company for any reason fails to tender the Notes for delivery to the Initial Purchaser, or (b) the Initial Purchaser declines to purchase the Notes for any reason permitted under this Agreement, the Company shall reimburse the Initial Purchaser for all reasonable out-of-pocket expenses (including fees and disbursements of counsel for the Initial Purchaser) incurred by the Initial Purchaser in connection with this Agreement and the proposed purchase of the Notes, and upon demand the Company shall pay the full amount thereof to the Initial Purchaser.

In rendering such opinion, such counsel may state that its opinion is limited to matters governed by the federal laws of the United States of America, the laws of the States of New York and California and the Delaware General Corporate Law.

The undersigned understands that you (the “Initial Purchaser”) propose to enter into a Purchase Agreement (the “Purchase Agreement”) providing for the purchase by the Initial Purchaser of Convertible Senior Notes due 2022 (the “Notes”) of Maxwell Technologies, Inc., a Delaware corporation (the “Company”). The Notes will be convertible into cash, shares of the Company’s common stock, par value $0.10 per share (the “Common Stock”), or a combination of cash and shares of Common Stock, at the Company’s election. The Initial Purchaser proposes to reoffer the Notes in Exempt Resales (as such term is defined in the Purchaser Agreement) (the “Offering”).

In consideration of the execution of the Purchase Agreement by the Initial Purchaser, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, during the period beginning from the date hereof and continuing to and including the date 90 days after the date of the preliminary offering memorandum relating to the Offering (the “Lock-Up Period”), the undersigned will not, directly or indirectly, (1) offer for sale, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise transfer or dispose of any shares of Common Stock, including but not limited to any securities that are convertible into or exchangeable for, or that represent the right to receive, shares of Common Stock or any such substantially similar securities, or any options or warrants to purchase any shares of Common Stock (collectively, “Securities”), (2) enter into any swap or other agreement or transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of shares of the Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Securities, in cash or otherwise, (3) make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock or any other securities of the Company, or (4) publicly disclose the intention to do any of the foregoing.

In furtherance of the foregoing, the Company and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

Notwithstanding the foregoing, the undersigned may transfer the undersigned’s Securities (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, (iii) pursuant to any contract, instruction or plan complying with Rule 10b5-1 under the Exchange Act (a “10b5-1 Plan”) that has been entered into by the undersigned prior to the date of this Lock-Up Letter Agreement and of which the Initial Purchaser or their counsel have been made aware, (iv) in the case of an option to purchase shares of Common Stock expiring during the Lock-Up Period or restricted stock units or performance stock units vesting during the Lock-Up Period, the sale or surrender of shares of Common Stock to the Company to pay the exercise price or withholding tax obligations in connection with the exercise of such option or vesting of such restricted stock units or performance stock units (but only to such extent) or (v) with the prior written consent of the Initial Purchaser; provided, that in the case of (i) and (ii) above, such transfer is not required to be reported under Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and provided further, that in the case of (iv) above, any report required to be filed in connection with such transaction under the Exchange Act shall include an explanatory note reflecting the circumstances of such surrender. This Lock-Up Letter Agreement shall not prohibit the establishment of a 10b5-1 Plan for the transfer of shares of Common Stock, provided that such plan does not provide for the transfer of Common Stock during the Lock-Up Period and no public announcement or filing under the Exchange Act regarding the establishment of such plan shall be required of or voluntarily made by or on behalf of the undersigned or the Company. For purposes of this Lock-Up Letter Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. The undersigned now has, and, except as contemplated by this paragraph, for the duration of this Lock-Up Letter Agreement will have, good and marketable title to the undersigned’s Securities, free and clear of all liens, encumbrances, and claims whatsoever. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s Securities except in compliance with the foregoing restrictions.

It is understood that if (i) the Company notifies the Initial Purchaser prior to the execution of the Purchase Agreement that it does not intend to proceed with the Offering, (ii) the Purchase Agreement is terminated prior to payment for and delivery of the Notes, or (iii) the Purchase Agreement has not been executed prior to October 15, 2017, then this Lock-Up Letter Agreement shall be of no further force or effect.

The undersigned understands that the Company and the Initial Purchaser will proceed with the Offering in reliance on this Lock-Up Letter Agreement.

Any Offering will only be made pursuant to a Purchase Agreement, the terms of which are subject to negotiation between the Company and the Initial Purchaser.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, legal representatives, successors and assigns of the undersigned.
