 Exhibit 10.6 
 AMERICAN SUPERCONDUCTOR CORPORATION 
 Amended and Restated Executive Severance Agreement

 THIS AMENDED AND RESTATED EXECUTIVE SEVERANCE AGREEMENT by and between American Superconductor Corporation, a
Delaware corporation (the “Company”), and Daniel P. McGahn (the “Executive”) is made as of December 23, 2008 (the “Effective Date”). 
 WHEREAS, the Board of Directors of the Company (the “Board”) has determined that appropriate steps should be taken to reinforce and encourage the continued employment and dedication of
the Executive and to minimize the distraction from the possibility of an unwarranted termination of employment. 
 WHEREAS,
the Company and the Executive acknowledge and agree that the benefits described in this Agreement are not intended to, and shall not, constitute a severance plan, and shall confer no benefit on anyone other than the parties hereto. 
 WHEREAS, the Company and the Executive originally entered into this Executive Severance Agreement on January 24, 2008, and now
desire to amend and restate it to reflect certain developments in the tax law. 
 NOW, THEREFORE, as an inducement for and in
consideration of the Executive remaining in its employ, the Company agrees that the Executive shall receive the severance benefits set forth in this Agreement in the event the Executive’s employment with the Company is terminated under the
specific circumstances described below.

 (a) the acquisition by an individual, entity or group (within the meaning of Section 13(d)(3) or
14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) (a “Person”) of beneficial ownership of any capital stock of the Company if, after such acquisition, such Person beneficially owns (within the
meaning of Rule 13d-3 promulgated under the Exchange Act) 50% or more of either (x) the then-outstanding shares of common stock of the Company (the “Outstanding Company Common Stock”) or (y) the combined voting power of the
then-outstanding securities of the Company entitled to vote generally in the election of directors (the “Outstanding Company Voting Securities”); provided, however, that for purposes of this subsection (a), the following
acquisitions shall not constitute a Change in Control: (i) any acquisition directly from the Company, or (ii) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or any corporation
controlled by the Company; or 







 (b) the Continuing Directors (as defined below) no longer constituting a majority of the
Board (or, if applicable, the Board of Directors of a successor corporation to the Company), where the term “Continuing Director” means at any date a member of the Board (i) who was a member of the Board on the date of the execution
of this Agreement or (ii) who was nominated or elected subsequent to such date by at least a majority of the directors who were Continuing Directors at the time of such nomination or election or whose election to the Board was recommended or
endorsed by at least a majority of the directors who were Continuing Directors at the time of such nomination or election; provided, however, that there shall be excluded from this clause (ii) any individual whose initial
assumption of office occurred as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents, by or on behalf of a person other than the
Board; or 
 (c) the consummation of a merger, consolidation, reorganization, recapitalization or statutory share exchange
involving the Company or a sale or other disposition of all or substantially all of the assets of the Company in one or a series of related transactions (a “Business Combination”), other than a Business Combination in which all or
substantially all of the individuals and entities who were the beneficial owners of the Outstanding Company Common Stock and Outstanding Company Voting Securities immediately prior to such Business Combination beneficially own, directly or
indirectly, immediately following such Business Combination, more than 50% of the then-outstanding shares of common stock and the combined voting power of the then-outstanding securities entitled to vote generally in the election of directors,
respectively, of the resulting or acquiring corporation in such Business Combination (which shall include, without limitation, a corporation which as a result of such transaction owns the Company or substantially all of the Company’s assets
either directly or through one or more subsidiaries) in substantially the same proportions as their ownership, immediately prior to such Business Combination, of the Outstanding Company Common Stock and Outstanding Company Voting Securities,
respectively. 
 1.2 “Change in Control Date” means the first date during the Term (as defined in
Section 2) on which a Change in Control occurs. 
 1.3 “Cause” means: 
 (a) the Executive’s failure to perform his reasonable assigned duties to the standards reasonably required by the Company (other
than any such failure resulting from incapacity due to physical or mental illness), which failure is not cured within 30 days after a written notice is received by the Executive from the Company describing in reasonable detail the manner in which
the Board of Directors believes the Executive has not performed the Executive’s duties to the standards reasonably required by the Company; or 
 (b) the Executive’s willful engagement in illegal conduct or gross misconduct that is materially injurious to the Company. For purposes of this Section 1.3(b), no act or failure to act by the Executive shall
be considered “willful” unless it is done intentionally and without reasonable belief that the Executive’s action was in the best interests of the Company.

 1.4 “Good Reason” means the occurrence, without the Executive’s
written consent, of any of the following events or circumstances:

(c) a material change in the geographic location at which the Executive must perform his duties; or 
 (d) any other action or inaction of the Company which constitutes a material breach by the Company of this Agreement. 
 Any termination by the Executive for Good Reason shall be communicated by means of a written notice delivered by the Executive to the
Company within 90 days of the initial existence of the occurrence or condition on which the Executive bases his claim for Good Reason. If the condition is capable of being corrected, the Company shall have 30 days during which it may remedy the
condition (the “Cure Period”). Notwithstanding the occurrence of any such event or circumstance, such occurrence shall not be deemed to constitute Good Reason if such event or circumstance has been fully corrected within the Cure
Period and the Executive has been reasonably compensated for any losses or damages resulting therefrom. If the condition is not corrected, the Executive must leave employment within one (1) year after the Company fails to cure the condition
giving rise to the Executive’s claim for Good Reason during the Cure Period. 
 1.5 “Disability” means
the Executive’s absence from the full-time performance of the Executive’s duties with the Company for 180 consecutive calendar days as a result of incapacity due to mental or physical illness which is determined to be total and permanent

 1.6 “Severance Period” shall mean the period of 12 months immediately following the Date of Termination (as defined in Section 3.2(a) below). 
 2. Term of Agreement. This Agreement, and all rights and obligations of the parties hereunder, shall take effect upon the
Effective Date and shall expire upon the first to occur of (a) the expiration of the Term (as defined below) if neither a termination of employment covered by Section 4.1(a) below nor a Change in Control occurred during the Term, or
(b) the fulfillment by the Company of all of its obligations under Section 4 following a termination of the Executive’s employment with the Company. “Term” shall mean the period commencing as of the Effective Date and
continuing in effect through March 31, 2011; provided, however, that commencing on April 1, 2011 and each April 1 thereafter (each hereinafter referred to as a “Renewal Date”), the Term shall be automatically extended
for one additional year so as to terminate four years from such Renewal Date, unless at least 90 days prior to such Renewal Date, the Company shall have given the Executive written notice that the Term will not be extended.

 3. Employment Status; Termination Following Change in Control. 
 3.1 Not an Employment Contract. The Executive acknowledges that this Agreement does not constitute a contract of employment or
impose on the Company any obligation to retain the Executive as an employee and that this Agreement does not prevent the Company or the Executive from terminating his employment at any time, before or after a Change in Control. 
 3.2 Termination of Employment. 
 (a) Any termination of the Executive’s employment by the Company at any time during the Term or at any time after the Change in Control Date, or by the Executive within 12 months following the Change in Control
Date (other than due to the death of the Executive) shall be communicated by a written notice to the other party hereto (the “Notice of Termination”), given in accordance with Section 6.2. Any Notice of Termination shall:

Reason, (ii) to the extent applicable, set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive’s employment for Cause or for Good Reason and (iii) specify the Date of
Termination (as defined below). The effective date of an employment termination (the “Date of Termination”) shall be the close of business on the date specified in the Notice of Termination (which date may not be less than 15 days or more
than 120 days after the date of delivery of such Notice of Termination), in the case of a termination other than one due to the Executive’s death, or the date of the Executive’s death, as the case may be. 
 (b) The failure by the Executive or the Company to set forth in the Notice of Termination any fact or circumstance which contributes to
a showing of Good Reason or Cause shall not waive any right of the Executive or the Company, respectively, hereunder or preclude the Executive or the Company, respectively, from asserting any such fact or circumstance in enforcing the
Executive’s or the Company’s rights hereunder. 
 (c) Any Notice of Termination for Cause given by the Company
must be given within 90 days of the occurrence of the event(s) or circumstance(s) that constitute(s) Cause. 
 (d) Any
Notice of Termination for Good Reason given by the Executive must be given within 90 days of the occurrence of the event(s) or circumstance(s) that constitute(s) Good Reason. 
 4. Benefits to Executive.

to the extent such health insurance benefits cannot be provided to non-employees, then the cash equivalent thereof, based on the cost thereof to the Company, which cash amount shall be paid proportionately over the Severance Period, monthly in
advance); provided, however: (1) that if the Executive becomes reemployed with another employer and is eligible to receive a particular type of benefits (e.g., health insurance benefits) from such employer on terms at least as favorable
to the Executive and his family as those being provided by the Company, then the Company shall no longer be required to provide those particular benefits to the Executive and his family; and (2) to the extent that such payments are taxable to

to the extent such health benefits cannot be provided to non-employees, then the cash equivalent thereof, based on the cost thereof to the Company, which cash amount shall be paid proportionately over the Severance Period, monthly in advance);
provided, however: (1) that if the Executive becomes reemployed with another employer and is eligible to receive a particular type of benefits (e.g., health insurance benefits) from such employer on terms at least as favorable to the
Executive and his family as those being provided by the Company, then the Company shall no longer be required to provide those particular benefits to the Executive and his family; and (2) to the extent that such payments are taxable to the

 6 








 
cash amount shall be paid proportionately over the Severance Period, monthly in advance); provided, however: (1) that if the Executive becomes
reemployed with another employer and is eligible to receive a particular type of benefits (e.g., health insurance benefits) from such employer on terms at least as favorable to the Executive and his family as those being provided by the Company,
then the Company shall no longer be required to provide those particular benefits to the Executive and his family; and (2) to the extent that such payments are taxable to the Executive and/or extend beyond the COBRA continuation period, then
such payments shall be made monthly in advance. 
 (c) Other Terminations. If, following the Change in Control Date,
the Executive’s employment with the Company is terminated other than under the circumstances described in Section 4.2(a) or Section 4.2(b), then the Company shall (i) pay the Executive (or his estate, if applicable), in a lump
sum in cash on the Date of Termination, the Accrued Obligations and (ii) to the extent not previously paid or provided, timely pay or provide to the Executive the Other Benefits, the distribution of which shall be subject to the provisions of
Section 4.7. 
 (d) Expenses. Subject to Section 4.7, the Company agrees to reimburse the Executive for all
legal and other fees and expenses that the Executive reasonably incurs as a result of any claim or dispute regarding the benefits due to the Executive pursuant to this Section 4.2 if the Executive prevails in such claim or dispute. 

4.3 Section 280G Provisions. 
 (a) Notwithstanding any other provision of this Agreement, in the event that the Company undergoes a Change in Ownership or Control (as defined below), the Company shall not be obligated to
provide to the Executive a portion of any Contingent Compensation Payments (as defined below) that the Executive would otherwise be entitled to receive to the extent necessary to eliminate Excess Parachute Payments (as defined below) for the
Executive, except as set forth in Section 4.3(b). For purposes of this Section 4.3, the Contingent Compensation Payments so eliminated shall be referred to as the “Eliminated Payments” and the aggregate amount (determined in
accordance with Treasury Regulation Section 1.280G-1, Q/A-30 or any successor provision) of the Contingent Compensation Payments so eliminated shall be referred to as the “Eliminated Amount.” 
 (b) Notwithstanding the provisions of Section 4.3(a), no such reduction in Contingent Compensation Payments shall be made if
(i) the Eliminated Amount (computed without regard to this sentence) exceeds (ii) 110% of the aggregate present value (determined in accordance with Treasury Regulation Section 1.280G-1, Q/A-31, Q/A-32, Q/A-33 or any successor
provisions) of the amount of any additional taxes that would be incurred by the Executive if the Eliminated Payments (determined without regard to this sentence) were paid to him (including, state and federal income taxes on the Eliminated Payments,
the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”, which term shall include applicable Treasury Regulations), payable with respect to all of the Contingent Compensation Payments in
excess of the Executive’s “base amount” (as defined in Section 280G(b)(3) of the Code), and any withholding taxes). The override of such reduction in Contingent Compensation Payments pursuant to this Section 4.3(b) shall be
referred to as a 

  

 7 








 
“Section 4.3(b) Override.” For purposes of this paragraph, if any federal, state or local income taxes would be attributable to the receipt of
any Eliminated Payment, the amount of such taxes shall be computed by multiplying the amount of the Eliminated Payment by the maximum combined federal, state and local income tax rate provided by law. 
 (c) For purposes of this Section 4.3 the following terms shall have the following respective meanings: 
 (i) “Change in Ownership or Control” shall mean a change in the ownership or effective control of the Company or in the
ownership of a substantial portion of the assets of the Company determined in accordance with Section 280G(b)(2) of the Code. 
 (ii) “Contingent Compensation Payment” shall mean any payment (or benefit) in the nature of compensation that is made or made available (under this Agreement or otherwise) to a “disqualified individual” (as defined in
Section 280G(c) of the Code) and that is contingent (within the meaning of Section 280G(b)(2)(A)(i) of the Code) on a Change in Ownership or Control of the Company. 
 (iii) “Excess Parachute Payment” shall mean a payment described in Section 280G(b)(1) of the Code. 
 (d) Any payments or other benefits otherwise due to the Executive following a Change in Ownership or Control that could reasonably be characterized (as determined by the Company) as Contingent
Compensation Payments (the “Potential Payments”) shall not be made until the dates provided for in this Section 4.3(d). 
 (i) In the event that the Company undergoes a Change in Ownership or Control, and the Executive becomes entitled to receive Contingent Compensation Payments relating to such Change in Ownership or Control, the Company
shall (A) determine at such time or times as may be necessary to comply with the requirements under Section 280G of the Code whether such Contingent Compensation Payments constitute in whole or in part Excess Parachute Payments and
(B) in the event the Company determines that such Contingent Compensation Payments constitute in whole or in part Excess Parachute Payments, notify the Executive (within 30 days after each such determination and with reasonable detail regarding
the basis for its determinations) of the following: (1) which Potential Payments constitute Contingent Compensation Payments, (2) the Eliminated Amount and (3) whether the Section 4.3(b) Override is applicable. 
 (ii) Within 30 days after delivery of such notice to the Executive, the Executive shall deliver a response to the Company (the
“Executive Response”) stating either (A) that he agrees with the Company’s determination pursuant to the preceding sentence, or (B) that he disagrees with such determination, in which case he shall set forth (1) which
Potential Payments should be characterized as Contingent Compensation Payments, (2) the Eliminated Amount, or (3) whether the Section 4.3(b) Override is applicable. 
 (iii) If and to the extent that any Contingent Compensation Payments are required to be treated as Eliminated Payments pursuant to this
Section 4.3, then the Payments shall be reduced or eliminated, as determined by the Company, in the following order: 

  

 8 








 
(A) any cash payments, (B) any taxable benefits, (C) any nontaxable benefits, and (D) any vesting of equity awards, in each case in reverse
order beginning with payments or benefits that are to be paid the farthest in time from the date that triggers the applicability of the excise tax, to the extent necessary to maximize the Eliminated Payments. 
 (iv) If the Executive fails to deliver an Executive Response on or before the required date, the Company’s initial determinations
shall be final, and the Company shall make the Potential Payments (other than the Eliminated Payments) to the Executive within 10 business days following the due date for delivery to the Company of the Executive Response (except for any Potential
Payments which are not due to be made until after such date, which Potential Payments shall be made on the date on which they are due). 
 (v) If the Executive states in the Executive Response that he agrees with the Company’s determinations, the Company’s initial determinations shall be final, the Contingent Compensation Payments that shall be
treated as Eliminated Payments shall be as set forth in the Executive Response, and the Company shall make the Potential Payments (other than the Eliminated Payments) to the Executive within 10 business days following delivery to the Company of the
Executive Response (except for any Potential Payments which are not due to be made until after such date, which Potential Payments shall be made on the date on which they are due). 
 (vi) If the Executive states in the Executive Response that he disagrees with the Company’s determinations, then, for a period of
60 days following delivery of the Executive Response, the Executive and the Company shall use good faith efforts to resolve such dispute. If such dispute is not resolved within such 60-day period, such dispute shall be settled exclusively by
arbitration in Boston, Massachusetts, in accordance with the rules of the American Arbitration Association then in effect. Judgment may be entered on the arbitrator’s award in any court having jurisdiction. The Company shall, within 10 business
days following delivery to the Company of the Executive Response, make to the Executive those Potential Payments as to which there is no dispute between the Company and the Executive regarding whether they should be made (except for any such
Potential Payments which are not due to be made until after such date, which Potential Payments shall be made on the date on which they are due). The balance of the Potential Payments (other than Eliminated Payments) shall be made within 10 business
days following the resolution of such dispute. 
 (vii) Subject to the limitations contained in Sections 4.3(a) and
(b) hereof, the amount of any payments to be made to the Executive following the resolution of such dispute shall be increased by amount of the accrued interest thereon computed at the prime rate announced from time to time by Bank of America,
compounded monthly from the date that such payments originally were due. 
 (viii) In the event the Company is required to
perform a redetermination in accordance with Treas. Reg. 1.280G-1 Q/A-33(b) with respect to any Contingent Compensation Payments, this Section 4.3(d) shall apply with respect to such redetermination and the parties shall make such adjustments
as may be necessary as a result of such redetermination including, if appropriate, the payment by the Company of Contingent Compensation Payments previously treated as Eliminated Payments if the Section 4.3(b) Override applies as a result of
such redetermination. 
  

 9 








 (e) The provisions of this Section 4.3 are intended to apply to any and all
payments or benefits available to the Executive under this Agreement or any other agreement or plan of the Company under which the Executive receives Contingent Compensation Payments. 
 4.4 Release. The obligation of the Company to make the payments and provide
the benefits to the Executive under Section 4.1(a), Section 4.2(a) or Section 4.2(b) is conditioned upon the Executive signing a release of claims in the form attached hereto as Exhibit A, or such other form as may be agreed to
by the Company and the Executive (the “Employee Release”), within 21 days (the “Release Period”) following the Date of Termination and upon the Executive not revoking the Employee Release in a timely manner thereafter. Provided
that the Employee Release has become binding, the payments to the Executive under Section 4.1(a), Section 4.2(a) or Section 4.2(b) shall be payable or shall commence on the 30th
 day following the Date of Termination. Notwithstanding the foregoing, the provisions of benefits under Section 4.1(a)(iii), Section 4.2(a)(iii) or Section 4.2(b)(iii) shall continue during
the Release Period and any applicable revocation period. 
 4.5 Exclusive Severance Benefits. The making of the
payments and the provision of the benefits by the Company to the Executive under Section 4.1(a), Section 4.2(a) or Section 4.2(b) shall constitute the entire obligation of the Company to the Executive as a result of the termination of
his employment under the circumstances set forth in such Sections, and the Executive shall not be entitled to additional payments or benefits under any other plan, program, policy, practice, contract or agreement of the Company or its subsidiaries.

 4.6 Mitigation. The Executive shall not be required to mitigate the amount of any payment or benefits provided for
in Section 4.1(a), Section 4.2(a) or Section 4.2(b) by seeking other employment or otherwise. Further, except as provided in Section 4.1(a)(iii), Section 4.2(a)(iii) or Section 4.2(b)(iii), the amount of any payment or
benefits provided for in Section 4.1(a), Section 4.2(a) or Section 4.2(b) shall not be reduced by any compensation earned or benefits received by the Executive as a result of employment by another employer. 
 4.7 Section 409A. Subject to this Section 4.7, any severance payments or benefits under this Agreement shall begin only
upon the date of the Executive’s “separation from service” (as determined below), which occurs on or after the date of the Executive’s termination. The following rules shall apply with respect to distribution of the payments and
benefits, if any, to be provided to the Executive under Sections 4.1 or 4.2, as applicable: 
 (a) It is intended that each
installment of the payments and benefits provided under Sections 4.1 and 4.2 shall be treated as a separate “payment” for purposes of Section 409A of the U.S. Internal Revenue Code of 1986, as amended, and the guidance issued
thereunder (“Section 409A”). Neither the Company nor the Executive shall have the right to accelerate or defer the delivery of any such payments or benefits except to the extent specifically permitted or required by Section 409A;

  

 10 








 (b) If, as of the date of the “separation from service” of the Executive from
the Company (within the meaning of Section 4.7(d) below), the Executive is not a “specified employee” (within the meaning of Section 409A), then each installment of the payments and benefits shall be made on the dates and terms
set forth in Sections 4.1 or 4.2, as applicable; and 
 (c) If, as of the date of the separation from service of the
Executive from the Company, the Executive is a specified employee, then: 
 (i) Each installment of the payments and
benefits due under Sections 4.1 or 4.2 that, in accordance with the dates and terms set forth herein, will in all circumstances, regardless of when the separation from service occurs, be paid within the short-term deferral period (as defined under
Section 409A) shall be treated as a short-term deferral within the meaning of Treasury Regulation Section 1.409A-1(b)(4) to the maximum extent permissible under Section 409A. 
 (ii) Each installment of the payments and benefits due under Sections 4.1 or 4.2 that is not described in Section 4.7(c)(i), above,
and that would, absent this subsection, be paid within the six-month period following the separation from service of the Executive from the Company shall not be paid until the date that is six months and one day after such separation from service
(or, if earlier, the Executive’s death), with any such installments that are required to be delayed being accumulated during the six-month period and paid in a lump sum on the date that is six months and one day following the Executive’s
separation from service and any subsequent installments, if any, being paid in accordance with the dates and terms set forth herein; provided, however, that the preceding provisions of this sentence shall not apply to any installment
of payments and benefits if and to the maximum extent that that such installment is deemed to be paid under a separation pay plan that does not provide for a deferral of compensation by reason of the application of Treasury
Regulation 1.409A-1(b)(9)(iii) (relating to separation pay upon an involuntary separation from service). Any installments that qualify for the exception under Treasury Regulation Section Section 1.409A-1(b)(9)(iii) must be paid no later
than the last day of the Executive’s second taxable year following his taxable year in which the separation from service occurs. 
 (d) The determination of whether and when a separation from service from the Company has occurred shall be made and in a manner consistent with and based on the presumptions set forth in, Treasury Regulation
Section 1.409A-1(h). Solely for purposes of this Section 4.7(d), “Company” shall include all persons with whom the Company would be considered a single employer as determined under Treasury Regulation Section 1.409A-1(h)(3).

 (e) All reimbursements and in-kind benefits provided under the Agreement shall be made or provided in accordance with the
requirements of Section 409A to the extent that such reimbursements or in-kind benefits are subject to Section 409A, including, where applicable, the requirement that (i) any reimbursement is for expenses incurred during the
Executive’s lifetime (or during a shorter period of time specified in this Agreement), (ii) the amount of expenses eligible for reimbursement during a calendar year may not affect the expenses eligible for reimbursement in any other
calendar year, (iii) the reimbursement of an eligible expense will be made on or before the last day of the calendar year following the year in which the expense is incurred and (iv) the right to reimbursement is not subject to set off or
liquidation or exchange for any other benefit.

 Exhibit A 
 RELEASE 
 In consideration of the payment to me of the severance benefits pursuant to
Section 4.1(a), 4.2(a) or 4.2(b) of my Executive Severance Agreement with American Superconductor Corporation (the “Company”) dated
                     [    ], 20     (the “Agreement”), I hereby agree as
follows: 
 1. I, on behalf of myself and my representatives, agents, estate, heirs, successors and assigns, hereby irrevocably and
unconditionally release, remise and discharge the Company, its officers, directors, stockholders, affiliates (within the meaning of the Securities Act of 1933), attorneys, agents and employees, and their respective predecessors, successors and
assigns (collectively, the “Company Releasees”), from any and all actions or causes of action, suits, claims, complaints, liabilities, contracts, torts, debts, damages, controversies, rights and demands, whether existing or contingent,
known or unknown, arising up to and through the date of this Release out of my employment, or the termination of my employment, with the Company, including, but not limited to, all employment discrimination claims under the Age Discrimination in

to any non-vested ownership interest in the Company, contractual or otherwise, including, but not limited to, claims to stock or stock options. Notwithstanding the foregoing, (a) nothing in this Release prevents me from filing, cooperating
with, or participating in any proceeding before the EEOC or a state Fair Employment Practices Agency (except that I acknowledge that I may not recover any monetary benefits in connection with any such claim, charge or proceeding), (b) this
Release does not extend to any rights I have that arise after the date hereof under the Agreement and (c) this Release does not extend to any rights I may have to indemnification as an officer or director of the Company under the provisions of

 5. This Release shall not become effective and in force until eight days after I sign, provided I have
not timely revoked my acceptance.
