 Exhibit 10.3 
 ABIOMED, Inc. 
 Restricted Stock Agreement 
 This Restricted Stock Agreement (this “Agreement”) is made effective as of
                    , between ABIOMED, Inc. (the “Company”), and
                     (the “Employee”), pursuant to the Company’s 2008 Stock Incentive Plan, as it may be amended from
time to time (the “Plan”). This Agreement is expressly subject to all of the terms and conditions contained in the Plan, which is hereby incorporated herein by reference. In the event that any of the terms and conditions contained
in this Agreement are inconsistent with the Plan, the terms of the Plan shall control. All capitalized terms not defined in this Agreement have the meanings specified in the Plan. 
 WITNESSETH: 
 WHEREAS, on
                     the Committee granted a Restricted Stock Award under Section 7 of the Plan to the Employee in the amount of
             shares of its Common Stock, $.01 par value of the Company (the “Shares”), subject to the restrictions set forth herein, including restrictions related
to the ability of the Employee to transfer the Shares and the forfeiture of any unvested Shares in the event of the termination of the Employee’s employment with the Company; and 
 WHEREAS, the Plan provides that a participant who is granted a Restricted Stock Award shall have no rights with respect to the Award unless the
participant shall have accepted the Award within sixty (60) days following the award date by making payment to the Company of the specified purchase price of the shares covered by the Award and by executing and delivering to the Company a
written instrument that sets forth the terms and conditions applicable to the Restricted Stock in such form as the Committee shall determine (the “Written Instrument”); 
 WHEREAS, the Committee has specified that the Shares be acquired at no cost; 
 WHEREAS, this Agreement constitutes the required Written Instrument the Employee must deliver to accept the Restricted Stock Award; and

 WHEREAS, the Employee wishes to accept the Restricted Stock Award by delivery to the Company of this Agreement; 
 NOW, THEREFORE, for valuable consideration, the receipt of which is hereby acknowledged, the Company and the Employee agree as follows:

 1. Forfeiture; Vesting. If the Employee ceases to be an employee, consultant or advisor to the Company or a subsidiary of the
Company at any time for any reason (the date this occurs being hereafter referred to as the “Termination Date”), whether because of any action of the Company or the Employee, the death or incapacity of the Employee or otherwise, all
Unvested Shares (as defined below) shall automatically be forfeited to the Company. For purposes of this Agreement, “Unvested Shares” means any Shares that are not Vested Shares, and “Vested Shares” means any Shares
that have vested in accordance with the following schedule: 
 [                                ] 
 [                                ] 
 [                                ] 
 [                                ] 

 Shares shall vest in each case only to the extent that the Employee remains an employee, consultant or
advisor to the Company or a subsidiary of the Company at such time. 
 2. Deposit of Shares. Simultaneously with the execution of this
Agreement, the Employee shall deposit with the Company the certificate or certificates representing all of the Stock and shall promptly upon acquisition of any additional shares of stock, as described in Section 6 hereof, deposit with the
Company the certificate or certificates for such additional shares. Any such additional shares shall for all purposes be deemed Shares under this Agreement. To all certificates deposited by the Employee with the Company, there shall be attached a
stock power or stock powers, duly executed by the Employee in blank, constituting and appointing the Company his attorney to transfer such stock on the books of the Company. The Company shall hold such certificates and stock powers for the purposes
of this Agreement. The Employee shall continue to be the owner of the Shares, despite such deposit and stock powers, and shall be entitled to exercise all rights of ownership in such Shares, subject, however, to the provisions of this Agreement.

 3. Restriction on Transfer. Other than as set forth in Section 1 with respect to forfeitures to the Company, the Employee
shall not sell, assign, transfer, pledge, hypothecate, mortgage, encumber or otherwise dispose of, voluntarily or involuntarily, by operation of law or otherwise (collectively, “transfer”), any of the Unvested Shares or any interest
therein, unless and until such Shares are no longer subject to the Repurchase Option. 
 4. Lock-Up Agreement. The Employee agrees
that upon the request of the Company or the managing underwriter(s) of any offering of securities of the Company that is the subject of a registration statement filed under the Securities Act of 1933, as amended, for a period of time (not to exceed
180 days, plus such additional number of days (not to exceed 35) as may reasonably be requested to enable the underwriter(s) of such offering to comply with Rule 2711(f) of the Financial Industry Regulatory Authority or any amendment or successor
thereto) from the effective date of the registration statement under the Act for such offering, the Employee will not sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any Shares, without the prior
written consent of the Company and such underwriters. 
 5. Restrictive Legends. All certificates representing the Shares shall have
affixed thereto legends in substantially the following form, in addition to any other legends that may be required under federal or state securities laws: 
 “The securities represented by this certificate are subject forfeiture and the restrictions on transfer set forth in an agreement between the Corporation and the registered holder hereof, a copy of which will be
provided to the holder hereof by the Corporation upon written request and without charge.”

 6. Adjustments for Stock Splits, Stock Dividends, etc. 
 6.1 If from time to time there is any stock split, stock dividend, stock distribution or other reclassification of the Common Stock of the Company, any
and all new, substituted or additional securities to which the Employee is entitled by reason of the Employee’s ownership of the Shares shall be immediately subject to the Repurchase Option and the restrictions on transfer and the other
provisions of this Agreement in the same manner and to the same extent as the Shares. 
 6.2 If the Shares are converted into or exchanged
for, or stockholders of the Company receive by reason of any distribution in total or partial liquidation, securities of another corporation, or other property (including cash), pursuant to any merger of the Company or acquisition of its assets,
then the rights of the Company under this Agreement shall inure to the benefit of the Company’s successor and this Agreement shall apply to the securities or other property received upon such conversion, exchange or distribution in the same
manner and to the same extent as to the Shares. 
 7. Change in Control. In order to preserve the Employee’s rights under this
Agreement in the event of a change in control of the Company, the Committee in its discretion may take one or more of the following actions: (i) provide for the acceleration of any time period relating to the vesting of the Shares,
(ii) adjust the terms of this Agreement in a manner determined by the Committee to reflect the change in control, (iii) cause this Agreement to be assumed, or new rights substituted therefor, by another entity, or (iv) make such other
provision as the Committee may consider equitable and in the best interests of the Company. 
 8. Discretion of the Committee. Unless
otherwise provided, the Committee shall make all determinations required to be made hereunder, including determinations required to be made by the Company, and shall interpret all provisions of this Agreement, as it deems necessary or desirable, in
its sole and unfettered discretion. Such determinations and interpretations shall be binding and conclusive to the Company and the Employee. If there shall be no Compensation Committee of the Corporation’s Board of Directors or if the Board of
Directors shall determine that the Board of Directors shall administer this Agreement, all references herein to the Committee shall be deemed references to the Board of Directors. 
 9. Withholding Taxes; No Section 83(b) Election. 
 9.1 The Employee acknowledges and agrees that the Company has the right to deduct from payments of any kind otherwise due to the Employee any federal, state or local taxes of any kind required by law to be withheld
with respect to the lapse of the Repurchase Option. 
 9.2 The Employee has reviewed with the Employee’s own tax advisors the federal,
state, local and foreign tax consequences of this investment and the transactions contemplated by this Agreement. The Employee is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. The
Employee 

  

 - 3 - 

 
understands that the Employee (and not the Company) shall be responsible for the Employee’s own tax liability that may arise as a result of the
Restricted Stock Award or the transactions contemplated by this Agreement. The Employee understands that no election under Section 83(b) of the Code has been, or will be, made with the IRS with respect to the Restricted Stock Award. 

10. No Rights To Employment. Nothing contained in this Agreement shall be construed as giving the Employee any right to continued employment
with the Company, or to establish or maintain an on-going business relationship with the Company. The Employee acknowledges and agrees that the transactions contemplated hereunder and the vesting schedule set forth herein do not constitute an
express or implied promise of continued engagement as a consultant or employee for the vesting period, for any period, or at all. 
 11.
Remedies. No transfer of Shares shall be effective or given effect on the books of the Company unless all of the applicable provisions of this Agreement have been duly complied with. If any transfer of Shares is made or attempted in violation
of the foregoing restrictions the Company shall have the right to cause the forfeiture of such Shares from the owner thereof or his transferee at any time before or after the transfer, as herein provided. In addition to any other legal or equitable
remedies which it may have, the Company may enforce its rights by actions for specific performance (to the extent permitted by law) and may refuse to recognize any transferee as one of its stockholders for any purpose, including, without limitation,
for purposes of dividend and voting rights, until all applicable provisions hereof have been complied with. 
 12. Fractional Shares.
No fractional shares shall vest under this Agreement and any calculation of Vested Shares that results in a fractional share shall be rounded down to a whole Share. 
 13. Assignment. The Company may assign any or all of its rights under this Agreement to one or more persons or entities. 
 14. Severability. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, and each other provision of this
Agreement shall be severable and enforceable to the extent permitted by law. 
 15. Waiver. Any provision for the benefit of the
Company contained in this Agreement may be waived, either generally or in any particular instance, by the Committee. 
 16. Binding
Effect. This Agreement shall be binding upon and inure to the benefit of the Company and the Employee and their respective heirs, executors, administrators, legal representatives, successors and assigns, subject to the restrictions on transfer
set forth in this Agreement. 
 17. Amendment. Subject to Section 14 of the Plan, the Committee may amend any conditions of this
Agreement. In all other cases, this Agreement may only be modified or amended by a writing signed by both parties.

 - 7 -Form of Change of Control Agreement

 Exhibit 10.4 
 AGREEMENT 
 AGREEMENT by and between ABIOMED, INC., a Delaware corporation (the “Company”), and
[                    ] (the “Executive”), dated as of the [    ] day of
[                    ], 2008. 
 The
Compensation Committee of the Board of Directors of the Company (the “Compensation Committee”), has determined that it is in the best interests of the Company and its shareholders to assure that the Company will have the continued
dedication of the Executive, notwithstanding the possibility, threat, or occurrence of a Change of Control (as defined below) of the Company. The Compensation Committee believes it is imperative to diminish the inevitable distraction of the
Executive by virtue of the personal uncertainties and risks created by a pending or threatened Change of Control and to encourage the Executive’s full attention and dedication to the Company currently and in the event of any threatened or
pending Change of Control, and to provide the Executive with compensation and benefits arrangements upon a Change of Control which ensure that the compensation and benefits expectations of the Executive will be satisfied and which are competitive
with those of other corporations. Therefore, in order to accomplish these objectives, the Compensation Committee has caused the Company to enter into this Agreement. 
 NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS: 
 1. Certain Definitions. (a) The “Effective
Date” shall be the first date during the “Change of Control Period” (as defined in Section 1(b)) on which a Change of Control (as defined in Section 2) occurs. Anything in this Agreement to the contrary notwithstanding, if
the Executive’s employment with the Company is terminated or the Executive ceases to be an officer of the Company prior to the date on which a Change of Control occurs, and it is reasonably demonstrated that such termination of employment
(1) was at the request of a third party who has 

 
taken steps reasonably calculated to effect the Change of Control or (2) otherwise arose in connection with or anticipation of the Change of Control,
then for all purposes of this Agreement the “Effective Date” shall mean the date immediately prior to the date of such termination of employment. 
 (b) The “Change of Control Period” is the period commencing on the date hereof and ending on the second anniversary of such date; provided, however that commencing on the date one year after the date hereof,
and on each annual anniversary of such date (such date and each annual anniversary thereof is hereinafter referred to as the “Renewal Date”), the Change of Control Period shall be automatically extended without any further action by the
Company or the Executive so as to terminate two years from such Renewal Date; provided, however, that if the Company shall give notice in writing to the Executive, at least sixty days prior to the Renewal Date, stating that the Change of Control
Period shall not be extended, then the Change of Control Period shall expire two years from the last effective Renewal Date. 
 2. Change
of Control. For the purpose of this Agreement, a “Change of Control” shall mean: 
 (a) The acquisition by any
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”)), of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the
Exchange Act) of thirty percent or more of the then outstanding shares of stock of the Company entitled to vote in the election of directors (the “Outstanding Company Common Stock”), whether in one transaction or in multiple transactions
which in the aggregate equal or exceed thirty percent of the Outstanding Company Common Stock; provided, however, 

  

 -2- 

 
that (i) any acquisition by the Company or its subsidiaries, or any employee benefit plan (or related trust) of the Company or its subsidiaries of
thirty percent or more of the Outstanding Company Common Stock shall not constitute a Change of Control; (ii) any acquisition by any individual, entity or group of beneficial ownership of thirty percent or more but less than forty percent of
the Outstanding Company Common Stock may be deemed by the Incumbent Board (as hereinafter defined), excluding any members of the Incumbent Board affiliated with the acquiror, to not constitute a Change of Control, in the Incumbent Board’s sole
and absolute discretion; and (iii) any acquisition by a corporation with respect to which, following such acquisition, more than fifty percent of the then outstanding shares of common stock of such corporation, is then beneficially owned,
directly or indirectly, by all or substantially all of the individuals and entities who were the beneficial owners of the Outstanding Company Common Stock immediately prior to such acquisition in substantially the same proportion as their ownership,
immediately prior to such acquisition, of the Outstanding Company Common Stock, shall not constitute a Change of Control; or 
 (b) Individuals who, as of the date of this Agreement, constitute the Board of the Directors (the “Board”) of the Company (together with any individuals deemed members of the Incumbent Board as set forth in this Section 2(b),
the “Incumbent Board”) cease for any reason to constitute at least a majority of the Board, provided that any individual becoming a director subsequent to the date of this Agreement whose election, or nomination for election by the
Company’s shareholders, was approved by a vote of at least a majority of the 

  

 -3- 

 
directors then comprising the Incumbent Board shall be considered as though such individual were a member of the Board on the date of this Agreement and a
member of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of office is in connection with either an actual or threatened election contest or other actual or threatened solicitation of proxies or
consents by or on behalf of a person other than the Board; or 
 (c) Approval by the stockholders of the Company of (i) a
reorganization, merger or consolidation, in each case, with respect to which all or substantially all of the individuals and entities who were the beneficial owners of the Outstanding Company Common Stock immediately prior to such reorganization,
merger or consolidation will not, following such reorganization, merger or consolidation, beneficially own, directly or indirectly, more than fifty percent of the then outstanding shares of common stock of the corporation resulting from such a
reorganization, merger or consolidation, other than a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no “person” (as such term is used in Sections 13(d) of the Exchange
Act) acquires thirty percent or more of Outstanding Company Common Stock; or (ii) the sale or other disposition of all or substantially all of the assets of the Company, excluding a sale or other disposition of assets to a subsidiary of the
Company and excluding a sale or license of a portion of the business of the Company which is deemed by the Incumbent Board, acting in its sole and absolute discretion, to not constitute a Change of Control. 
  

 -4- 

 Anything in this Agreement to the contrary notwithstanding, if an event that would, but for this
paragraph, constitute a Change of Control results from or arises out of a purchase or other acquisition of the Company, directly or indirectly, by a corporation or other entity in which the Executive has a greater than ten percent direct or indirect
equity interest, such event shall not constitute a Change of Control. 
 3. Employment Period. Subject to the terms and conditions
hereof, the Company hereby agrees to continue the Executive in its employ for the period commencing on the Effective Date and ending on the last day of the twenty-fourth month following the month in which the Effective Date occurs (the
“Employment Period”). The Executive hereby agrees to remain in the employ of the Company for the period commencing on the Effective Date and ending on the last day of the sixth month following the month in which the Effective Date occurs
(the “Six Month Period”). 
 4. Terms of Employment. (a) Position and Duties. (i) Except as provided in
Section 4(c) below, during the Employment Period, (A) the Executive’s position (including status, offices, titles and reporting requirements), authority, duties and responsibilities shall be at least commensurate in all material
respects with the most significant of those held, exercised and assigned at any time during the one hundred and eighty-day period immediately preceding the Effective Date and (B) the Executive’s services shall be performed at the location
where the Executive was employed immediately preceding the Effective Date or any office or location less than thirty-five miles from such location. 
 (ii) During the Employment Period, and excluding any periods of vacation and sick leave to which the Executive is entitled, the Executive agrees to devote his full business time to the business and affairs of the Company and, to the extent
necessary to discharge the 

  

 -5- 

 
responsibilities assigned to the Executive hereunder, to use the Executive’s reasonable best efforts to perform faithfully and efficiently such
responsibilities. During the Employment Period it shall not be a violation of this Agreement for the Executive to (A) serve on corporate, civic or charitable boards or committees, (B) deliver lectures, fulfill speaking engagements or teach
at educational institutions and (C) manage personal investments, so long as such activities do not significantly interfere with the performance of the Executive’s responsibilities as an employee of the Company in accordance with this
Agreement. It is expressly understood and agreed that to the extent that any such activities have been conducted by the Executive prior to the Effective Date, the continued conduct of such activities (or the conduct of activities similar in nature
and scope thereto) subsequent to the Effective Date shall not thereafter be deemed to interfere with the performance of the Executive’s responsibilities to the Company. 
 (b) Compensation. (i) Base Salary. During the Employment Period, the Executive shall receive an annual base salary (“Annual Base
Salary”), which shall be paid at a monthly rate, at least equal to twelve times the highest monthly base salary paid or payable to the Executive by the Company in respect of the twelve-month period immediately preceding the month in which the
Effective Date occurs. Any increase in Annual Base Salary shall not serve to limit or reduce any other obligation to the Executive under this Agreement. Annual Base Salary shall not be reduced after any such increase and the term Annual Base Salary
as utilized in this Agreement shall refer to Annual Base Salary as so increased. 
 (ii) Annual Bonus. In addition to Annual Base
Salary, the Executive shall be awarded, for each fiscal year during the Employment Period, an annual bonus (the “Annual Bonus”) in cash at least equal to the target bonus of the Executive (annualized for any fiscal year consisting of less
than twelve full months or with respect to which the Executive has been 

  

 -6- 

 
employed by the Company for less than twelve full months) in respect of the fiscal year in which the Effective Date occurs (the “Target Bonus”).
Each such Annual Bonus shall be paid no later than the fifteenth day of the third month of the fiscal year next following the fiscal year for which the Annual Bonus is awarded. 
 (iii) Incentive, Savings and Retirement Plans. In addition to Annual Base Salary and Annual Bonus payable as hereinabove provided, the Executive
shall be entitled to participate during the Employment Period in all incentive, savings and retirement plans, practices, policies and programs applicable to other peer executives of the Company, but in no event shall such plans practices, policies
and programs provide the Executive with incentive, savings and retirement benefits opportunities, in each case, less favorable, in the aggregate, than the most favorable of those provided by the Company for the Executive under such plans, practices,
policies and programs as in effect at any time during the one-year immediately preceding the Effective Date. 
 (iv) Welfare Benefit
Plans. During the Employment Period, the Executive and/or the Executive’s family, as the case may be, shall be eligible for participation in and shall receive all benefits under welfare benefit plans, practices, policies and programs
provided by the Company (including, without limitation, medical, prescription, dental, disability, salary continuance, employee life, group life, accidental death and travel accident insurance plans and programs) and applicable to other peer
executives of the Company, but in no event shall such plans, practices, policies and programs provide benefits which are less favorable, in the aggregate, than the most favorable of such plans, practices, policies and programs in effect at any time
during the one-year period immediately preceding the Effective Date. 
  

 -7- 

 (v) Expenses. During the Employment Period, the Executive shall be entitled to receive prompt
reimbursement for all reasonable expenses incurred by the Executive in the conduct of the Company’s business upon submission of appropriate accountings in accordance with the most favorable policies, practices and procedures of the Company in
effect at any time during the one-year period immediately preceding the Effective Date. Notwithstanding anything in this Agreement to the contrary, to the extent necessary to comply with Code Section 409A, (a) the amount of any expenses
eligible for reimbursement under this Agreement in any taxable year of the Executive shall not affect the expenses eligible for reimbursement in any other taxable year, and (b) the reimbursement of expenses under this Agreement shall be made no
later than on or before the last day of the Executive’s taxable year following the taxable year in which the expense was incurred, except to the extent earlier reimbursement is required under this Agreement or Company policies and procedures.

 (vi) Fringe Benefits. During the Employment Period, the Executive shall be entitled to fringe benefits in accordance with the most
favorable plans, practices, programs and policies of the Company in effect at any time during the one-year period immediately preceding the Effective Date. If at the end of the Employment Period, the Company elects not to continue to employ the
Executive for reasons other than for Cause, death or Disability, or if the Executive shall terminate employment hereunder, the Company will provide to the Executive up to $10,000 in fees paid for out-placement assistance. 
 (vii) Office and Support Staff. During the Employment Period, the Executive shall be entitled to an office or offices of a size and with
furnishings and other appointments, and to exclusive personal secretarial and other assistance, at least equal to the most favorable of the foregoing provided to the Executive by the Company at any time during the one-year period immediately
preceding the Effective Date. 
  

 -8- 

 (viii) Vacation. During the Employment Period, the Executive shall be entitled to paid vacation in
accordance with the most favorable plans, policies, programs and practices of the Company as in effect at any time during the one-year period immediately preceding the Effective Date. 
 (c) Six Month Period. Notwithstanding anything to the contrary in this Section 4, during the Six Month Period, the Company’s obligations
under this Agreement with respect to the duties and responsibilities of the Executive are limited to employing the Executive in any capacity reasonably assigned to the Executive by the Company to assist in the transition caused by the Change of
Control at the location where the Executive was employed immediately preceding the Effective Date or at any office or location less than thirty-five miles from such location and providing to the Executive compensation and benefits as set forth in
Section 4(b) hereof in accordance with the most favorable plans, practices, policies and programs provided by the Company for the Executive as in effect at any time during the one year period immediately preceding the Effective Date.

 (d) Change of Control; Acceleration in Connections with Cancellations. If in connection with a Change of Control, the Board or the
Compensation Committee of the Board shall exercise its authority under any stock option or stock incentive plan of the Company to cancel outstanding stock options, stock appreciation rights or restricted stock as of the time when such Change of
Control shall occur, then to the extent Executive shall hold any stock options, stock appreciation rights or restricted stock that is to be so cancelled, all such to-be-cancelled unvested stock options or stock appreciation rights of the Executive
shall be immediately and 

  

 -9- 

 
automatically exercisable for ten days before such Change of Control and all such to-be-cancelled restricted stock held by the Executive shall be fully
vested as of a time immediately before such Change of Control. 
 5. Termination of Employment. (a) Death or Disability.
The Executive’s employment shall terminate automatically upon the Executive’s death during the Employment Period. If the Company determines in good faith that the Disability of the Executive has occurred during the Employment Period
(pursuant to the definition of “Disability” set forth below), it may give to the Executive written notice in accordance with Section 12(b) of this Agreement of its intention to terminate the Executive’s employment. In such event,
the Executive’s employment with the Company shall terminate effective on the thirtieth day after receipt of such notice by the Executive (the “Disability Effective Date”), provided that, within the thirty days after such receipt, the
Executive shall not have returned to full-time performance of the Executive’s duties. For purposes of this Agreement, “Disability” means the absence of the Executive from the Executive’s duties with the Company on a full-time
basis for 180 consecutive business days as a result of incapacity due to mental or physical illness which is determined to be total and permanent by a physician selected by the Company or its insurers and acceptable to the Executive or the
Executive’s legal representative (such agreement as to acceptability not to be withheld unreasonably). 
 (b) Cause. The Company
may terminate the Executive’s employment during the Employment Period for “Cause”. For purposes of this Agreement, “Cause” means (i) an act or acts of personal dishonesty taken by the Executive and intended to result in
substantial personal enrichment of the Executive at the expense of the Company, (ii) repeated violations by the Executive of the Executive’s obligations under Section 4(a) of this Agreement (other than as a 

  

 -10- 

 
result of incapacity due to physical or mental illness) which are demonstrably willful and deliberate on the Executive’s part, which are committed in
bad faith or without reasonable belief that such violations are in the best interests of the Company and which are not remedied in a reasonable period of time after receipt of written notice from the Company or (iii) the commission by the
Executive of a crime (other than routine traffic offenses). 
 (c) Good Reason. The Executive’s employment may be terminated
during the Employment Period by the Executive for Good Reason. For purposes of this Agreement, “Good Reason” means: 
 (i) the assignment to the Executive of any duties inconsistent in any respect with the Executive’s position (including status, offices, titles and reporting requirements), authority, duties or responsibilities as contemplated by
Section 4(a) of this Agreement, or any other action by the Company which results in a diminution in such position, authority, duties or responsibilities, excluding for this purpose an isolated, insubstantial and inadvertent action not taken in
bad faith and which is remedied by the Company promptly after receipt of notice thereof given by the Executive; 
 (ii) any
failure by the Company to comply with any of the provisions of Section 4(b) of this Agreement, other than an isolated, insubstantial and inadvertent failure not occurring in bad faith and which is remedied by the Company promptly after receipt
of notice thereof given by the Executive; 
 (iii) any failure by the Company to fulfill its obligations to the Executive
during the Six Month Period, as set forth in Section 4(c) of this Agreement, other than an isolated, insubstantial and inadvertent failure not occurring in bad faith and which is remedied by the Company promptly after receipt of notice thereof
given by the Executive; 
  

 -11- 

 (iv) the Company’s requiring the Executive to be based at any office or location
other than the location where the Executive was employed immediately preceding the Effective Date or any office or location less than thirty-five miles from such location; 
 (v) any purported termination by the Company of the Executive’s employment otherwise than as expressly permitted by this Agreement;
or 
 (vi) any failure by the Company to comply with and satisfy Section 10(c) of this Agreement. 
 Notwithstanding the foregoing, during the Six Month Period, “Good Reason” shall mean (iii), (iv), (v) or (vi) above only. For
purposes of this Section 5(c), any good faith determination of “Good Reason” after the Six Month Period made by the Executive shall be conclusive. 
 (d) Notice of Termination. Any termination by the Company for Cause or without Cause or by the Executive for Good Reason shall be communicated by Notice of Termination to the other party hereto given in
accordance with Section 12(b) of this Agreement. For purposes of this Agreement, a “Notice of Termination” means a written notice which (i) indicates the specific termination provision in this Agreement relied upon, if
applicable, (ii) to the extent applicable, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive’s employment under the provision so indicated, and (iii) if the Date of
Termination (as defined below) is other than the date of receipt of such notice, specifies the termination date (which date shall be not more than fifteen days after the giving of such notice). The failure by the Executive or the Company to set
forth in the Notice of Termination any fact or 

  

 -12- 

 
circumstance which contributes to a showing of Good Reason or Cause shall not waive any right of the Executive or the Company hereunder or preclude the
Executive or the Company from asserting such fact or circumstance in enforcing the Executive’s or the Company’s rights hereunder. 
 (e) Date of Termination. “Date of Termination” means the date of receipt of the Notice of Termination or any later date specified therein, as the case may be; provided however, that (i) if the Executive’s
employment is terminated by the Company other than for Cause, death or Disability, the Date of Termination shall be the date on which the Company notifies the Executive of such termination and (ii) if the Executive’s employment is
terminated by reason of death or Disability, the Date of Termination shall be the date of death of the Executive or the Disability Effective Date, as the case may be. 
 6. Obligations of the Company upon Termination. 
 (a) Death. If the Executive’s employment
is terminated by reason of the Executive’s death during the Employment Period, this Agreement shall terminate without further obligations to the Executive’s legal representatives under this Agreement, other than payment of the sum of the
following amounts: (i) the Executive’s Annual Base Salary through the Date of Termination to the extent not theretofore paid, (ii) the product of (A) the greater of (x) the Annual Bonus paid or payable (and annualized for
any fiscal year consisting of less than twelve full months or for which the Executive has been employed for less than twelve full months) to the Executive for the Company’s most recently completed fiscal year, and (y) the Target Bonus and
(B) a fraction, the numerator of which is the number of days in the current fiscal year through the Date of Termination, and the denominator of which is 365, and (iii) any accrued bonus amounts or vacation pay, in each case, to the extent
not yet paid by the Company (the amounts described in 

  

 -13- 

 
subparagraphs (i), (ii), and (iii) are hereafter referred to as “Accrued Obligations” and shall be paid to the Executive’s estate or
beneficiary, as applicable, in a lump sum in cash within sixty days of the Date of Termination. Subject to the provisions of Section 9 hereof, but, otherwise, anything herein to the contrary notwithstanding, the Executive’s family shall be
entitled to receive benefits at least equal to the most favorable benefits provided by the Company to surviving families of peer executives of the Company under such plans, programs, practices and policies relating to family death benefits, if any,
as in effect with respect to other peer executives and their families at any time during the one year period immediately preceding the Effective Date. 
 (b) Disability. If the Executive’s employment is terminated by reason of the Executive’s Disability during the Employment Period, this Agreement shall terminate without further obligations of the
Company to the Executive, other than for payment of the Accrued Obligations (which shall be paid in a lump sum in cash within sixty days of the Date of Termination). Subject to the provisions of Section 9 hereof, but, otherwise, anything herein
to the contrary notwithstanding, the Executive shall be entitled after the Disability Effective Date to receive disability and other benefits at least equal to the most favorable of those provided by the Company to disabled executives and/or their
families in accordance with such plans, programs, practices and policies relating to disability, if any, as in effect with respect to other peer executives and their families at any time during the one year period immediately preceding the Effective
Date. 
 (c) Cause. If the Executive’s employment shall be terminated by the Company for Cause during the Employment Period, this
Agreement shall terminate without further obligations of the Company to the Executive other than the obligation to pay to the Executive Annual Base 

  

 -14- 

 
Salary through the Date of Termination, plus any accrued and awarded bonus amounts or vacation pay, in each case, to the extent theretofore unpaid. In such
case, such amounts shall be paid to the Executive in a lump sum in cash within thirty days of the Date of Termination, except that accrued and awarded bonus amounts, if any, shall be paid as previously scheduled at the time of the award. The
Executive shall, in such event, also be entitled to any benefits required by law that are not otherwise provided by this Agreement. 
 (d)
Other Than for Cause, Death or Disability; Termination by the Executive. If, during the Employment Period, the Company shall terminate the Executive’s employment other than for Cause, death or Disability or if the Executive shall
terminate employment under this Agreement (other than during the Six Month Period): 
 (i) the Company shall pay to the
Executive in a lump sum in cash within thirty days after the Date of Termination the aggregate of the following amounts: 
 A.
all Accrued Obligations; and 
 B. the amount (such amount shall be hereinafter referred to as the “Severance
Amount”) equal to the product of (I) [            ] and (II) the Executive’s then-effective Annual Base Salary plus the applicable Target Bonus; 
 (ii) the Company shall timely pay and provide, for twenty-four months from the Date of Termination, medical and dental benefits to the
Executive and/or the Executive’s family at least equal to those which would have been provided in accordance with the applicable plans, programs, practices and policies described in Section 4(b)(iv) of this Agreement as if the
Executive’s employment had not been terminated in accordance with the most favorable plans, practices, programs 

  

 -15- 

 
or policies of the Company as in effect and applicable generally to other peer executives and their families during the one year period immediately preceding
the Effective Date, provided, however, that if the Executive becomes re-employed with another employer and is eligible to receive medical and dental benefits under another employer provided plan, the medical and dental benefits described herein
shall be secondary to those provided under such other plan during such applicable period of eligibility and provided, further, that if any Company plan would not allow the Executive to participate, the Company shall provide to the Executive
comparable tax-adjusted payments of an equivalent amount; and 
 (iii) to the extent not theretofore paid or provided, the
Company shall timely pay or provide to the Executive and/or the Executive’s family any other amounts or benefits required to be paid or provided or which the Executive and/or the Executive’s family is eligible to receive pursuant to this
Agreement and under any plan, program, policy or practice or contract or agreement of the Company as in effect and applicable generally to other peer executives of the Company and their families, including up to $10,000 in fees paid for
out-placement assistance (such other amounts and benefits shall be hereinafter referred to as the “Other Benefits”); and 
 (iv) in the case the Company shall terminate the Executive’s employment other than for Cause, death or Disability or in the case the Executive shall terminate employment under this Agreement for Good Reason (but not otherwise), all
remaining unvested stock options or stock appreciation rights which the Executive then holds to acquire securities from the Company shall be 

  

 -16- 

 
immediately and automatically exercisable as of the Date of Termination and all restricted stock of the Company which the Executive then holds shall be fully
vested as of such Date. 
 7. Non-exclusivity of Rights. Except as provided in Section 6, nothing in this Agreement shall prevent
or limit the Executive’s continuing or future participation in any benefit, bonus, incentive or other plans, programs, policies or practices, provided by the Company and for which the Executive may qualify, nor shall anything herein limit or
otherwise affect such rights as the Executive may have under any other agreements with the Company. Amounts which are vested benefits or which the Executive is otherwise entitled to receive under any plan, policy, practice or program of the Company
at or subsequent to the Date of Termination shall be payable in accordance with such plan, policy, practice or program except as explicitly modified by this Agreement. 
 8. Full Settlement. (a) The Company’s obligation to make the payments provided for in this Agreement and otherwise to perform its obligations hereunder shall not be affected by any set-off,
counterclaim, recoupment, defense or other claim, right or action which the Company may have against the Executive or others. In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the
amounts payable to the Executive under any of the provisions of this Agreement and, except as provided in Section 6(d)(ii), such amounts shall not be reduced whether or not the Executive obtains other employment. The Company agrees to pay
promptly as incurred, to the full extent permitted by law, all legal fees and expenses which the Executive may reasonably incur as a result of any contest (regardless of the outcome thereof) by the Company, the Executive or others of the validity or
enforceability of, or liability under, any provision of this Agreement or any guarantee 

  

 -17- 

 
of performance thereof (including as a result of any contest by the Executive about the amount of any payment pursuant to this Agreement, unless a court of
competent jurisdiction determines that the Executive made such effort in bad faith), plus in each case interest at the applicable Federal rate provided for in Section 7872(f)(2)(A) of the Internal Revenue Code of 1986, as amended (the
“Code”). 
 (b) If there shall be any dispute between the Company and the Executive (i) in the event of any termination of the
Executive’s employment by the Company, whether such termination was for Cause, or (ii) in the event of any termination of employment by the Executive, whether Good Reason existed, then, unless and until there is a final, nonappealable
judgment by a court of competent jurisdiction declaring that such termination was for Cause or that the determination by the Executive of the existence of Good Reason was not made in good faith, the Company shall pay all amounts, and provide all
benefits, to the Executive and/or the Executive’s family or other beneficiaries, as the case may be, that the Company would be required to pay or provide pursuant to Section 6(d) as though such termination were by the Company without
Cause, or by the Executive with Good Reason, as applicable; provided, however, that the Company shall not be required to pay any disputed amount pursuant to this paragraph except upon receipt of an undertaking by or on behalf of the Executive to
repay all such amounts to which the Executive is ultimately adjudged by such court not to be entitled. 
 9. Certain Additional Payments
by the Company. 
 (a) Anything in this Agreement to the contrary notwithstanding, in the event that it shall be determined that any
payment or distribution by the Company to or for the benefit of the Executive (determined without regard to any additional payments required under this Section 9)(a “Payment”), would be subject to the excise tax imposed by
Section 4999 of the Code or any 

  

 -18- 

 
interest or penalties are incurred by the Executive with respect to such excise tax (such excise tax, together with any such interest and penalties, are
hereinafter collectively referred to as the “Excise Tax”), the Company shall make an additional payment with respect to such Excise Tax (a “Gross-Up Payment”) to the Executive in an amount such that, after payment by the
Executive of all taxes (including any interest or penalties imposed with respect to such taxes), including, without limitation, any income taxes (and any interest and penalties imposed with respect thereto) and Excise Tax imposed upon the Gross-Up
Payment, the Executive retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments; provided, however, that if the amount of the Payment subject to the Excise Tax exceeds the amount of the Severance Payment specified
under Section 6(d)(i)(B), the Gross-Up Payment shall be reduced to an amount equal to the amount calculated pursuant to the above provisions as if the Payment subject to the Excise Tax were equal to the amount of the Severance Payment specified
under Section 6(d)(i)(B). 
 (b) Subject to the provisions of Section 9(c), all determinations required to be made under this
Section 9, including whether and when a Gross-Up Payment is required and the amount of such Gross-Up Payment and the assumptions to be utilized in arriving at such determination, shall be made by the Company’s independent registered public
accounting firm, unless such firm shall be the accounting firm of the individual, entity or group effecting the Change of Control or such firm declines the engagement, in which case such determinations shall be made by an accounting firm of national
standing agreed to by the Company and the Executive, or, if the Company does not so agree within 10 days of the Date of Termination, such an accounting firm shall be selected by the Executive, (the “Accounting Firm”) which shall provide
detailed supporting calculations both to the Company and the Executive within fifteen business 

  

 -19- 

 
days of the date such firm is selected or such earlier time as is requested by the Company. All fees and expenses of the Accounting Firm shall be borne
solely by the Company. Any Gross-Up Payment, as determined pursuant to this Section 9, shall be paid by the Company to the Executive within five days of the receipt of the Accounting Firm’s determination. If the Accounting Firm determines
that no Excise Tax is payable by the Executive, it shall furnish the Executive with a written opinion that failure to report the Excise Tax on the Executive’s applicable federal income tax return would not result in the imposition of a
negligence, accuracy-related or similar penalty. Any such determination by the Accounting Firm shall be binding upon the Company and the Executive. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the
initial determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments which will not have been made by the Company should have been made (“Underpayment”), consistent with the calculations required to be made
hereunder. In the event that the Company exhausts its remedies pursuant to Section 9(c) and the Executive thereafter is required to make a payment of any Excise Tax, the Accounting Firm shall determine that amount of the Underpayment that has
occurred and any such Underpayment shall be promptly paid by the Company to or for the benefit of the Executive. 
 (c) The Executive shall
notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by the Company of the Gross-Up Payment. Such notification shall be given as soon as practicable but no later than ten business
days after the Executive is informed in writing of such claim and shall apprise the Company of the nature of such claim and the date on which such claim is requested to be paid. The Executive shall not pay such claim prior to the expiration of the
30-day period following the date on which it gives such notice to the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies the Executive in writing prior to the
expiration of such period that it desires to contest such claim, the Executive shall: 
 (i) give the company any information
reasonably requested by the Company relating to such claim, 
  

 -20- 

 (ii) take such action in connection with contesting such claim as the Company shall
reasonably request in writing from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company, 
 (iii) cooperate with the Company in good faith in order effectively to contest such claim, and 
 (iv) permit the Company to participate in any proceedings relating to such claim; 
 provided, however, that the Company shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with such
contest and shall indemnify and hold the Executive harmless, on an after-tax basis, for any Excise Tax or income tax (including interest and penalties with respect thereto) imposed as a result of such representation and payment of costs and
expenses. Without limitation on the foregoing provisions of this Section 9(c), the Company shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forgo any and all administrative appeals,
proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct the Executive to pay the tax claimed and sue for a refund or contest the claim in any permissible manner, and the
Executive agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine; provided, however, that if the 

  

 -21- 

 
Company directs the Executive to pay such claim and sue for a refund, the Company shall advance the amount of such payment to the Executive, on an
interest-free basis and shall indemnify and hold the Executive harmless, on an after-tax basis, from any Excise Tax or income tax (including interest or penalties with respect thereto) imposed with respect to such advance; and further provided that
any extension of the statute of limitations relating to payment of taxes for the taxable year of the Executive with respect to which such contested amount is claimed to be due is limited solely to such contested amount. Furthermore, the
Company’s control of the contest shall be limited to issues with respect to which a Gross-Up Payment would be payable hereunder and the Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal
Revenue Service or any other taxing authority. 
 (d) If, after the receipt by the Executive of an amount advanced by the Company pursuant to
Section 9(c), the Executive becomes entitled to receive any refund with respect to such claim, the Executive shall (subject to the Company’s complying with the requirements of Section 9(c)) promptly pay to the Company the amount of
such refund (together with any interest paid or credited thereon after taxes applicable thereto). If, after the receipt by the Executive of an amount advanced by the Company pursuant to Section 9(c), a determination is made that the Executive
shall not be entitled to any refund with respect to such claim and the Company does not notify the Executive in writing of its intent to contest such denial of refund prior to the expiration of 30 days after such determination, then such advance
shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the extent thereof, the amount of Gross-Up Payment required to be paid. 
 10. Successors. (a) This Agreement is personal to the Executive and without the prior written consent of the Company shall not be assignable
by the Executive otherwise than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by the Executive’s legal representatives. 
  

 -22- 

 (b) This Agreement shall inure to the benefit of and be binding upon the Company and its successors and
assigns. 
 (c) The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all
or substantially all of the business and/or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken
place. As used in this Agreement, “Company” shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law, or otherwise.
In addition, the Executive shall be entitled, upon exercise of any outstanding stock options or stock appreciation rights of the Company, to receive in lieu of shares of the Company’s stock, shares of such stock or other securities of such
successor as the holders of shares of the Company’s stock received pursuant to the terms of the merger, consolidation or sale. 
 11.
Compliance with Code Section 409A. It is the intent of the parties that the payment of all amounts under this Agreement shall either qualify for exemption from or comply with the requirements of Code Section 409A, and any
ambiguities herein will be interpreted to so comply. Notwithstanding anything in this Agreement to the contrary, if the Executive is a “specified employee” for purposes of Code Section 409A at the time of a “termination of
employment” (as determined in accordance with regulations issued pursuant to Code Section 409A), payments made by reason of such termination of employment shall, to the extent such payments are considered to be “deferred
compensation” (within the meaning of Treasury 

  

 -23- 

 
Regulation Section 1.409A-1(b)(1)), be made within ten (10) days after the end of the six-month period beginning on the date of the
Executive’s separation from service (as defined under Section 409A) or, if earlier, the appointment of the personal representative or executor of the Executive’s estate upon his death, to the extent the delay contemplated by the foregoing
is required to avoid a prohibited distribution under Code Section 409A(a)(2). To the extent that any amount of any payment that would otherwise be made upon termination of employment is delayed as provided in this Section 11, (i) upon
payment such amount shall include interest at the applicable federal rate as determined pursuant to Code Section 1274(d) from the date of such termination of employment through the date of payment; and (ii) if all or any portion of such
amount is not paid as provided in this Section 11 and the Executive brings suit or otherwise takes action to recover such amount or enforce the provisions of this Agreement, the Executive shall be reimbursed by the Company for any reasonable
attorneys’ fees incurred in connection with such suit or action. 
 12. Miscellaneous. (a) This Agreement shall be governed
by and construed in accordance with the laws of The Commonwealth of Massachusetts, without reference to principles of conflict of laws. The captions of this Agreement are not part of the provisions hereof and shall have no force or effect. This
Agreement may not be amended or modified otherwise than by a written agreement executed by the parties hereto or their respective successors and legal representatives. 
 (b) All notices and other communications hereunder shall be in writing and shall be given by hand delivery to the other party or by registered or certified mail, return receipt requested, postage prepaid, addressed as
follows: 
 If to the Executive: 
 [                    ] 
 [                    ] 
 [                    ]

 If to the Company: 
 ABIOMED, Inc. 
 33 Cherry Hill Drive 
 Danvers, MA 01923 
 Attention: Chief Executive Officer 
 or to
such other address as either party shall have furnished to the other in writing in accordance herewith. Notices and communications shall be effective when actually received by the addressee. 
 (c) The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this
Agreement. 
 (d) The Company may withhold from any amounts payable under this Agreement such Federal, state or local taxes as shall be
required to be withheld pursuant to any applicable law or regulation. 
 (e) The Executive’s or the Company’s failure to insist
upon strict compliance with any provision hereof shall not be deemed to be a waiver of such provision or any other provision thereof. 
 (f)
This Agreement and the employment agreement between the Company and the Executive (the “Employment Agreement”) contain the entire understanding of the Company and the Executive with respect to the subject matter hereof and by entering into
this Agreement the Executive waives all rights he may have under the Company’s separation policy, provided that if the Company’s separation policy would provide greater benefits to the Executive than this 

  

 -25- 

 
Agreement, than the Executive may elect to receive benefits under the Company’s separation policy in lieu of the benefits provided hereunder. In the
event of any conflict between a provision of the Employment Agreement and a provision of this Agreement, the provision of this Agreement shall control. Without limiting the generality of the foregoing, it is expressly acknowledged that the
definition of “Cause” in this Agreement shall be controlling in all respects with respect to the Executive’s employment following the Effective Date. 
 (g) The Executive and the Company acknowledge that, except as may otherwise be provided under the Employment Agreement, prior to the Effective Date and following the end of the Employment Period, the employment of the
Executive by the Company is “at will” and may be terminated by either the Executive or the Company at any time. Moreover, if prior to the Effective Date, the Executive’s employment with the Company terminates, then the Executive shall
have no further rights under this Agreement. 
 (h) As used in this Agreement, “Company” shall mean the Company as hereinbefore
defined and any successor to its business or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law, or otherwise. 
  

 -26- 

 IN WITNESS WHEREOF, the Executive has hereunto set his hand and, pursuant to the authorization from its
Compensation Committee of the Board, the Company has caused these presents to be executed in its name on its behalf, all as of the day and year first above written.
