Exhibit 10.3







EMPLOYMENT AGREEMENT


This Employment Agreement (the "Agreement") is entered into as of March 8, 2016 (the "Effective Date"), by and between MacroGenics, Inc., a Delaware corporation, including its successors and assigns (the "Employer" or "Company"), and Ezio Bonvini, M.D. ("Executive").


In consideration of the promises and the respective undertakings of Employer and Executive set forth below, Employer and Executive hereby agree as follows:


1. Employment.  Employer hereby employs Executive, and Executive hereby accepts such employment and agrees to perform services for Employer, for the period and on the other terms and subject to the conditions set forth in this Agreement.


2. Employment at Will.  Executive is employed "at-will" which means that Executive's employment is not for any defined term and may be terminated by either Executive or the Company at any time, with or without cause, for any or no reason, subject to the notice provisions in Section 5.


3. Position and Duties.


3.01. Service with Employer.  Employer hereby employs Executive in an executive capacity with the title of Senior Vice President, Research ("Title"), and Executive hereby accepts such employment and undertakes and agrees to serve in such capacity.  Subject to the overall policy directives of the Board of Directors (the "Board") and applicable law, in Executive's capacity as Title, Executive shall have such powers, perform such duties and fulfill such responsibilities as are typically associated with such position in other similarly situated companies.


3.02. Performance of Duties.  Executive agrees to: (i) devote substantially all of Executive's business time, attention and efforts to the business and affairs of Employer while employed; and (ii) adhere to all Employer's written employment policies and procedures as shall be in force from time to time.  Executive shall perform Executive's duties primarily at the Company's headquarters in Rockville, Maryland, but is expected to travel as Company business necessitates.


3.03. Outside Activities.  During the term of Executive's employment with the Company pursuant to this Agreement, Executive shall not, except as set forth below: (i) accept other employment; (ii) render or perform services for compensation to any Person (as hereinafter defined) other than Employer; (iii) serve as an officer or on the board of directors (or similar governing body) of any entity other than Employer, whether or not for compensation; or (iv) engage in any other business or professional activity that will require any effort on the part of Executive that, in the sole discretion of Employer, could reasonably be expected to materially detract from the ability of Executive to perform Executive's duties to Employer pursuant to this Agreement; provided, however, Executive may engage in the activities (x) set forth in Schedule 1 hereto (as may be amended from time to time by mutual written agreement of the parties) so long as in doing so Executive is not in any way competing with the Company and such outside activities do not materially detract from Executive's performance of his duties hereunder or (y) described in clause (iii) or (iv) above if prior to engaging in such activity described in clause (iii) or (iv), Executive has disclosed such activity to the Board and received written approval to engage in such activity from the Board.  Executive may engage in personal investments without disclosure to or written approval from the Board provided Executive is not required or expected to serve as a board member, advisor or consultant and Executive shall, at any time, own beneficially less than 5% of the outstanding securities of any issuer and such personal investment shall not otherwise interfere with Executive's performance of duties hereunder and/or the provisions of Executive's written agreements with Employer.  Although Executive may be engaged in outside activities pursuant to this section, nothing herein is intended to limit or waive Executive's fiduciary duties.


3.04. Executive Representations.  Executive represents that Executive is not subject to any restrictive covenant, confidentiality agreement, or any other agreement that would prevent Executive from accepting employment with Employer, and based on the information provided to Employer by Executive, Employer accepts such representation.


4. Compensation.


4.01. Base Salary.  Employer shall pay to Executive an annual base salary for all services to be rendered by Executive under this Agreement of $360,500 (the "Base Salary"), which Base Salary shall be paid in accordance with Employer's normal payroll schedule, procedures and policies (which schedule, procedures and policies may be modified from time to time) and subject to applicable deductions as required by law.  Employer shall review Executive's salary on an annual basis and may, in its discretion, consider and declare from time to time increases in the Base Salary that it pays Executive.  Any and all increases in Executive's salary pursuant to this section shall cause the level of Base Salary to be increased by the amount of each such increase for purposes of this Agreement.  The increased level of Base Salary as provided in this section shall become the level of Base Salary for the remainder of the term of this Agreement unless there is a further increase in Base Salary as provided herein.


4.02. Annual Bonus.  Executive shall also be eligible to receive, in addition to the Base Salary, an annual bonus having a target amount equal to 35% of Executive's Base Salary ("Target Bonus"), with the actual amount being determined by the Compensation Committee of the Board in its discretion taking into account the Company's performance and Executive's individual performance.  In order to receive a Target Bonus, Executive must be employed by Employer on the date the bonus is paid. 


4.03. Participation in Benefit Plans.  Executive shall be entitled to participate in all employee benefit plans or programs offered to other senior executives from time to time (to the extent that Executive meets the requirements for each such plan or program), including participation in any health insurance plan, disability insurance plan, dental plan, eye care plan, 401(k) plan, life insurance plan, or other similar plans (all such benefits, the "Benefit Plans").


4.04. Expenses.  Employer shall reimburse Executive for all ordinary and necessary business expenses reasonably incurred by Executive in the performance of Executive's duties under this Agreement, subject to the presentment and approval of appropriate itemized expense statements, receipts, vouchers or other supporting documentation in accordance with Employer's normal policies for expense verification in effect from time to time.


4.05. Vacation.  Executive shall be entitled to twenty (20) vacation days per calendar year, accruing in accordance with the Company's vacation policy.  Executive may carry over up to a maximum of 200 hours of annual leave (including sick pay) at any time, and any unused vacation time beyond that will be forfeited.


4.06. Total Compensation.  Other than as may be approved by the Board, Executive shall not receive any other compensation or benefits from the Company other than as provided in Sections 4.01 through 4.06 hereof.


5. Payments Upon Termination.


5.01. Voluntary Resignation without Good Reason.  Executive may terminate Executive's employment by providing Employer with 30 days' advance written notice, which notice period may be waived by the Company in its discretion and will be deemed to be waived in the case of the Executive's effective resignation due to death or Disability (as defined below).  If Executive terminates Executive's employment (other than for Good Reason (as defined below) or by reason of death or Disability (as defined below)) (i) Employer shall pay to Executive the Accrued Obligations (as defined below), (ii) Executive's participation in the Benefit Plans shall terminate as of the Termination Date, and (iii) Employer shall have no other obligations to Executive under this Agreement, other than those provided in this Section 5.01.

The Accrued Obligations payable hereunder shall be paid no later than sixty (60) days following Executive's Termination Date.








	
(b)

	
For purposes of this Agreement, "Termination Date" means: the effective date of Executive's "separation from service" as defined in Section 409A of the Internal Revenue Code, or any applicable successor provision in effect at the Termination Date (the "Code").







5.02. Termination by Employer For Cause.  If Executive is terminated for Cause: (i) Employer shall pay to Executive the Accrued Obligations, (ii) Executive's participation in the Benefit Plans shall terminate as of the Termination Date, and (iii) Employer shall have no further obligations to Executive under this Agreement, other than those provided in this Section 5.02.  For purposes of this Agreement, "Cause" means: (a) Executive's failure to substantially perform Executive's duties with the Company (if Executive has not cured such failure to substantially perform, if curable, within thirty (30) days after Executive's receipt of written notice thereof from the Board that specifies the conduct constituting Cause under this clause (a)); (b) Executive's willful misconduct, or gross negligence in the performance of Executive's duties hereunder; (c) the conviction of Executive, or the entering by Executive of a guilty plea or plea of no contest with respect to, any crime that constitutes a felony or involves fraud, dishonesty or moral turpitude; (d) Executive's commission of an act of fraud, embezzlement or misappropriation against the Company; (e) Executive's material breach of the fiduciary duty owed by Executive to Company; (f) Executive's engaging in any improper conduct that has or is likely to have an adverse economic or reputational impact on the Company; or (g) Executive's material breach of this Agreement (if Executive has not cured such breach, if curable, within thirty (30) days after Executive's receipt of written notice thereof from the Board that specifies the conduct constituting Cause under this clause (g)).


5.03. Termination by Employer Without Cause or by Executive for Good Reason.  If Executive is terminated by Employer without Cause or by Executive for Good Reason: (i) Employer shall pay to Executive the Accrued Obligations, (ii) Executive shall be entitled to receive the Severance Benefits (as defined below in Section 5.05 and subject to the conditions described therein and in Section 5.06,  (iii) Employer shall pay to Executive any earned, but unpaid, bonus obligation relating to the prior fiscal year payable at the same time as bonuses are paid to the senior management team (but not later than March 15 of the subsequent fiscal year) and (iv) Employer shall have no further obligations to Executive under this Agreement, other than those provided in this Section 5.03. For purposes of this Agreement, "Good Reason" means the occurrence of any of the following events (without Executive's consent):



	
(a)

	
a material adverse change in Executive's functions, duties, or responsibilities as Title with the Company, which change would cause Executive's position to become one of materially lesser responsibility, importance, or scope;








	
(b)

	
a material change in the geographic location at which Executive must perform services to the Company of 50 miles or more from the Company's headquarters in Rockville, Maryland (unless Executive is permitted to telecommute rather than work at the Company's new headquarters); or








	
(c)

	
a material breach of this Agreement by the Company.







Notwithstanding the foregoing, no such event shall constitute "Good Reason" unless (A) Executive shall have given written notice of such event to the Company within six (6) months after the initial occurrence thereof, (B) the Company shall have failed to cure the condition constituting Good Reason within thirty (30) days following the delivery of such notice (or such longer cure period as may be agreed upon by the parties), and (C) Executive terminates employment within thirty (30) days after expiration of such cure period.


5.04. Termination by Employer due to Executive's Death or Disability.  If Executive's employment is terminated by reason of death or Disability (as defined below): (i) Employer shall pay to Executive the Accrued Obligations, (ii) Employer shall pay to Executive any earned, but unpaid, bonus obligation relating to the prior fiscal year payable at the same time as bonuses are paid to the senior management team (but not later than March 15 of the subsequent fiscal year), (iii) Executive's participation in the Benefit Plans shall terminate as of the Termination Date (except to the extent Executive is eligible for continued death or disability benefits under the applicable Employer plan), and (iv) Employer shall have no further obligations to Executive under this Agreement, other than those provided in this Section 5.04.  For the purposes of clarity, nothing in this Section 5.04 is to be construed as limiting Executive's right to recover insurance proceeds under the Company's life or disability insurance benefit plans that would otherwise be applicable to Executive's death or Disability. For purposes of this Agreement, "Disability" means (a) Executive being determined to be totally disabled as defined by guidelines of the then-existing Company disability insurance plan in which Executive is participating, or (b) a determination by the Social Security Administration that the Executive is "totally disabled" or (c) Executive's inability to engage in comparable professional activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than twelve months.


5.05. Severance Benefits:  "Severance Benefits" means:



	
(a)

	
The payment to Executive of the Severance Amount in substantially equal installments over one year (with the first payment commencing on the first payroll date that occurs at least 28 days following the Termination Date), in accordance with Employer's normal payroll practices ("Severance Period").  If the Executive's termination is in connection with or in the twelve (12) months following a Change of Control, then Severance Amount means (i) one year of Executive's then-current Base Salary plus (ii) the Target Bonus multiplied by the Executive's then-current Base Salary. If the Executive's termination precedes a Change of Control, then Severance Amount means (x) one year of Executive's then-current Base Salary plus (y) the Target Bonus multiplied by the Executive's then-current Base Salary, prorated for the number of days that have elapsed between January 1 of the calendar year of termination and the Termination Date.








	
(b)

	
The continuation of Executive's participation in the Company's medical, dental, and vision benefit plans at the same premium cost to Executive as charged to Executive immediately prior to the Termination Date for a period of twelve (12) months immediately following the Termination Date, or if earlier, until Executive obtains other employment which provides the same type of benefit; provided, however, that (a) it is understood and agreed that such continued medical, dental and vision benefits may at the election of the Company be provided by Executive electing the continuation of such coverage pursuant to COBRA with the Company reimbursing Executive for COBRA premiums to the extent required so that Executive's premium cost for the coverage in effect for Executive prior to the Termination Date is substantially the same as immediately prior to the Termination Date, and (b) if the Company determines, in its reasonable judgment, that providing medical, dental, and/or vision benefits in accordance with the preceding provisions of this Section 5.05(b) would result in a violation of applicable law, the imposition of any penalties under applicable law, or adverse tax consequences for participants covered by the Company's medical, dental, and/or vision plans, the Company may terminate such coverage (or reimbursement) with respect to Executive and instead pay to Executive taxable cash payments at the same time and in the same amounts as the Company would have paid as premiums (or as COBRA premium reimbursements) to provide such coverage. 








	
(c)

	
If the Termination Date occurs upon or within one year after the occurrence of a Change in Control, each stock option granted by the Company to Executive that is outstanding as of the Termination Date and is not fully vested as of the date of the Termination Date shall, as of the date Executive provides the Company with the Irrevocable Release provided for in Section 5.06 (but only if the Irrevocable Release is provided within the period provided for by Section 5.06), become vested with respect to 100% of the shares with respect to which the stock option is not vested as of the Termination Date; provided, however that in no event shall any such option vest to the extent the option has expired prior to the date Executive provides the Company with the Irrevocable Release.  For the avoidance of doubt, in the event that any of Executive's unvested stock options are to be terminated in connection with a Change of Control, Executive shall nonetheless be entitled to the accelerated vesting of 100% of the unvested stock options described in and subject to the conditions of this clause (c).








	
(i)

	
For purposes of this Agreement, "Change of Control" means, and shall be deemed to have occurred, if:








	
a.

	
any Person, excluding (i) employee benefit plans of the Company or any of its Affiliates, is or becomes the "beneficial owner" (as defined in Rules 13d-3 and 13d-5 under the Exchange Act, which Rules shall apply for purposes of this clause (a) whether or not the Company is subject to the Exchange Act), directly or indirectly, of Company securities representing more than fifty percent (50%) of the combined voting power of the Company's then outstanding securities ("Voting Power");








	
b.

	
the Company consummates a merger, consolidation, share exchange, division or other reorganization or transaction of the Company (a "Fundamental Transaction") with any other corporation, other than a Fundamental Transaction that results in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) at least fifty percent (50%) of the combined Voting Power immediately after such Fundamental Transaction of (i) the Company's outstanding securities, (ii) the surviving entity's outstanding securities, or (iii) in the case of a division, the outstanding securities of each entity resulting from the division;








	
c.

	
the stockholders of the Company approve a plan of complete liquidation or winding‐up of the Company or the consummation of the sale or disposition (in one transaction or a series of transactions) of all or substantially all of the Company's assets; or








	
d.

	
during any period of 24 consecutive months, individuals who at the beginning of such period constituted the Board (including for this purpose any new director whose election or nomination for election by the Company's stockholders was approved by a vote of at least two-thirds (2/3) of the directors then still in office who were directors at the beginning of such period or whose appointment, election or nomination was previously so approved or recommended) cease for any reason to constitute at least a majority of the Board.













	
(d)

	
The foregoing payment of Severance Benefits are expressly conditioned on receipt by the Company of an Irrevocable Release (as defined below) and the expiration of any statutory revocation period without any such revocation. To the extent such an Irrevocable Release has not been received by the Company, the time periods for payment of the Severance Benefits may be tolled by the Company until receipt of such an Irrevocable Release and expiration of such revocation period, at which point the Company may make a one-time catch-up payment for the applicable time period and then resume the regular periodic payment of Severance Benefits as provided in this Section 5.05.







5.06 Required Delivery of Irrevocable Release; Compliance with Section 6 Obligations.  Notwithstanding the provisions of Section 5.05, as a condition to entitlement to the Severance Benefits, Executive must provide to the Company an Irrevocable Release not later than the twenty-first (21st) day after the Date of Termination (or longer, to the extent there is an applicable statutory period pursuant to which Executive may consider and/or revoke such release and such period has lapsed without any such revocation).  In the event Executive fails to provide an Irrevocable Release to the Company within such period, the Company will immediately cease to pay or provide any further Severance Benefits and no accelerated vesting of stock options pursuant to Section 5.05(c) shall occur.   "Irrevocable Release" means a confidential separation agreement and release of claims, in the form attached Exhibit A (as may be modified to reflect any change in laws or regulations that would pertain to such an agreement and release at the time of separation) that has been executed by Executive, delivered to the Company, and become irrevocable by Executive.  In addition, in the event that Executive breaches the obligations under Section 6 of this Agreement at any time during the Severance Period, Executive will cease to be entitled to any further Severance Benefits.

6.01. Confidential Information and Goodwill.  In consideration of Executive's promises and covenants contained in this Agreement, including Executive's promise and covenant not to disclose Confidential Information, Employer will provide Executive with Confidential Information.

To the extent that Executive's duties involve sales or customer relations, the Company will permit Executive to utilize the Goodwill in Executive's sales efforts and will provide sales support to Executive similar to that which it provides to its sales representatives.


6.02. Duties.  While employed by Company, Executive shall perform the duties required of Executive hereunder and shall devote Executive's best efforts and, subject to the matters set forth on Schedule 1 (as amended from time to time by mutual written agreement of the parties), exclusive business time, energy and skill to performing such duties; not make any disparaging remarks regarding Company to any person with whom Company has business relations, including any employee or vendor of Company; use the Goodwill solely for the benefit of Company; and not interfere in such Goodwill, either during or following Executive's employment with Company.

The parties acknowledge that Company is the sole and exclusive owner of Confidential Information, and that Company has legitimate business interests in protecting Confidential Information.  The parties further acknowledge that Company has invested, and continues to invest, considerable amounts of time and money in obtaining, developing, and preserving the confidentiality of Confidential Information and that, by reason of the trust relationship arising between Executive and Company, Executive owes Company a fiduciary duty to preserve and protect Confidential Information from all unauthorized disclosure and unauthorized use.  Executive shall not, directly or indirectly, disclose Confidential Information to any third party (except to Executive's attorneys, the Company's personnel, other persons designated in writing by the Company, or except as otherwise provided by law) or use Confidential Information for any purpose other than for the direct benefit of Company while in Company's employ and thereafter.


6.05. Inventions and Assignment.  Executive agrees that he will promptly disclose to the Company any and all Company Inventions and that Executive hereby irrevocably assigns to the Company all ownership rights in and to any and all Company Inventions.

The term "Inventions" means discoveries; developments; trade secrets; processes; formulas; data; lists; software programs; graphics; artwork; logos, and all other works of authorship, ideas, concepts, know-how, designs, and techniques, whether or not any of the foregoing is or are patentable, copyrightable, or registrable under any intellectual property laws or industrial property laws in the United States.  The term "Company Inventions" means all Inventions that (a) relate to the business or proposed business of the Company or any of its predecessors or that are discovered, developed, created, conceived, reduced to practice, made, learned or written by Executive, either alone or jointly with others, in the course of Executive's  employment; (b) utilize, incorporate or otherwise relate to Confidential Information; or (c) are discovered, developed, created, conceived, reduced to practice, made, or written by him using property or equipment of the Company or any of its predecessors.  Executive agrees to promptly and fully communicate in writing to the Company (to such department or officer of the Company and in accordance with such procedures as the Company may direct from time to time) any and all Company Inventions.  Executive acknowledges and agrees that any work of authorship by Executive or others comprising Company Inventions shall be deemed to be a "work made for hire," as that term is defined in the United States Copyright Act (17 U.S.C.  § 101 (2000)).  To the extent that any such work of authorship may not be deemed to be a work made for hire, Executive hereby irrevocably assigns any ownership rights Executive may have in and to such work to the Company.  This Agreement does not apply to any Inventions Executive made or to which Executive contributed before Executive's employment with the Company.

the time periods covered by the promises and covenants will not include any period(s) of violation of, or any period(s) of time required for litigation brought by Company to enforce any such promise or covenant, it being understood that the extension of time provided in this paragraph may not exceed two (2) years.







6.09. [Reserved.]


6.10. Independent Elements.  The parties acknowledge that the promises and covenants contained in Section 6 above are essential independent elements of this Agreement and that, but for Executive agreeing to comply with them, Company would not employ Executive.  Accordingly, the existence or assertion of any claim by Executive against Company, whether based on this Agreement or otherwise, shall not operate as a defense to Company's enforcement of the promises and covenants in Section 6.  An alleged or actual breach of the Agreement by Company will not be a defense to enforcement of any such promise or covenant, or other obligations of Executive to Company.  The promises and covenants in Section 6 will remain in full force and effect whether Executive is terminated by Company or voluntarily resigns.


6.11. Remedies for Breach of Agreement.  Executive acknowledges that Executive's breach of any promise or covenant contained in Section 6 will result in irreparable injury to Company and that Company's remedies at law for such a breach will be inadequate. Accordingly, Executive agrees and consents that Company, in addition to all other remedies available at law and in equity, shall be entitled to both preliminary and permanent injunctions to prevent and/or halt a breach or threatened breach by Executive of any such promise or covenant, and Executive waives the requirement of the posting of any bond in connection with such injunctive relief.  Executive further acknowledges and agrees that the promises and covenants contained in Section 6 are enforceable, reasonable, and valid.


6.12 Directors and Officers Insurance.  During Executive's period of employment with the Company (and for any applicable "tail-period" thereafter), Executive shall be covered under a director and officer's liability insurance policy that provides insurance coverage for Executive on substantially the same terms and conditions as the other senior executives of the Company.







7. Miscellaneous.


7.01. Governing Law; Arbitration



	
(a)

	
This Agreement is made under and shall be governed by and construed in accordance with the laws of Maryland, without regard to its conflicts of law principles.








	
(b)

	
With respect to claims by the Company against Executive related to Executive's threatened or actual breach of Section 6 of this Agreement, each Party hereby irrevocably agrees that all actions or proceedings concerning such disputes may be brought by the Company in (a) the United States District Court for the District of Maryland; or (b) in any court of the State of Maryland sitting in Montgomery County, provided that the United States District Court lacks subject matter jurisdiction over such action or proceeding.  Executive consents to jurisdiction of and venue in the courts in the State of Maryland set forth in this Section, and hereby waives to the maximum extent permitted by applicable law any objection which Executive may have based on improper venue or forum non conveniens.








	
(c)

	
Except to the extent provided for in subsection (b) above,  the Company and Executive agree that any claim, dispute or controversy arising under or in connection with this Agreement, or otherwise in connection with Executive's employment by the Company or termination of his employment (including, without limitation, any such claim, dispute or controversy arising under any federal, state or local statute, regulation or ordinance or any of the Company's employee benefit plans, policies or programs) shall be resolved solely and exclusively by binding, confidential, arbitration.  The arbitration shall be held in Rockville, MD (or at such other location as shall be mutually agreed by the parties).  The arbitration shall be conducted in accordance with the Commercial Rules of the American Arbitration Association (the "AAA") in effect at the time of the arbitration, including the Expedited Procedures.  All fees and expenses of the arbitration, including a transcript if either requests, shall be borne equally by the parties.  Each party is responsible for the fees and expenses of its own attorneys, experts, witnesses, and preparation and presentation of proofs and post-hearing briefs (unless the party prevails on a claim for which attorney's fees are recoverable under law).  In rendering a decision, the arbitrator shall apply all legal principles and standards that would govern if the dispute were being heard in court.  This includes the availability of all remedies that the parties could obtain in court.  In addition, all statutes of limitation and defenses that would be applicable in court, will apply to the arbitration proceeding.  The decision of the arbitrator shall be set forth in writing, and be binding and conclusive on all parties.  Any action to enforce or vacate the arbitrator's award shall be governed by the Federal Arbitration Act, if applicable, and otherwise by applicable state law.  If either the Company or Executive improperly pursues any claim, dispute or controversy against the other in a proceeding other than the arbitration provided for herein, the responding party shall be entitled to dismissal or injunctive relief regarding such action and recovery of all costs, losses and attorney's fees related to such action. If Company and Executive cannot mutually agree on selection of an arbitrator, the AAA rules then in effect regarding arbitrator selection will be used to select an arbitrator.







7.02. Entire Agreement.  This Agreement and the documents referenced herein (including applicable stock option agreements and the equity plans to which they relate) contain the entire agreement of the parties relating to the employment of Executive by Employer and the ancillary matters discussed herein and supersedes all prior agreements, negotiations and understandings with respect to such matters, including, without limitation, any term sheet between the parties hereto with respect to such matters, and the parties hereto have made no agreements, representations or warranties relating to such employment or ancillary matters which are not set forth herein.


7.03. Withholding Taxes.  Employer may withhold from any compensation and Benefits payable under this Agreement all federal, state, city or other taxes as shall be required pursuant to any law or governmental regulation or ruling.


7.04. Golden Parachute Limit.  Notwithstanding any other provision of this Agreement, in the event that any portion of the Severance Benefits or any other payment or benefit received or to be received by Executive (whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement) (collectively, the "Total Benefits") would be subject to the excise tax imposed under Section 4999 of the Code (the "Excise Tax"), the Total Benefits shall be reduced to the extent necessary so that no portion of the Total Benefits is subject to the Excise Tax; provided, however, that no such reduction in the Total Benefits shall be made if by not making such reduction, Executive's Retained Amount (as hereinafter defined) would be more than ten percent (10%) greater than Executive's Retained Amount if the Total Benefits are so reduced.  All determinations required to be made under this Section 7.04 shall be made by tax counsel selected by the Company and reasonably acceptable to Executive ("Tax Counsel"), which determinations shall be conclusive and binding on Executive and the Company absent manifest error.  All fees and expenses of Tax Counsel shall be borne solely by the Company.  Prior to any reduction in Executive's Total Benefits pursuant to this Section 7.04, Tax Counsel shall provide Executive and the Company with a report setting forth its calculations and containing related supporting information.  In the event any such reduction is required, the Total Benefits shall be reduced in the following order: (i) the Severance Amount (in reverse order of payment), (iii) any other portion of the Total Benefits that are not subject to Section 409A of the Code (other than Total Benefits resulting from any accelerated vesting of equity awards), (iv) other Total Benefits that are subject to Section 409A of the Code in reverse order of payment, and (v) Total Benefits that are not subject to Section 409A and arise from any accelerated vesting of any equity awards.  "Retained Amount" shall mean the present value (as determined in accordance with sections 280G(b)(2)(A)(ii) and 280G(d)(4) of the Code) of the Total Benefits net of all federal, state and local taxes imposed on Executive with respect thereto.


7.05. Compliance With Section 409A.  This Agreement is intended to comply with the requirements of Section 409A of the Code (including the exceptions thereto), to the extent applicable, and shall be interpreted accordingly.  If any provision contained in this Agreement conflicts with the requirements of Section 409A of the Code (or the exemptions intended to apply under this Agreement), this Agreement shall be deemed to be reformed to comply with the requirements of Section 409A of the Code (or applicable exemptions thereto).  Notwithstanding anything to the contrary herein, for purposes of determining Executive's entitlement to the Severance Benefits under Section 5 hereof, (a) Executive's employment shall not be deemed to have terminated unless and until Executive incurs a "separation from service" as defined in Section 409A of the Code, and (b) the effective date of any termination or resignation of employment (or any similar term) shall be the effective date of Executive's separation from service.  Reimbursement of any expenses provided for in this Agreement shall be made in accordance with the Company's policies (as applicable) with respect thereto as in effect from time to time (but in no event later than the end of calendar year following the year such expenses were incurred) and in no event shall (i) the amount of expenses eligible for reimbursement hereunder during a taxable year affect the expenses eligible for reimbursement in any other taxable year or (ii) the right to reimbursement be subject to liquidation or exchange for another benefit.  Notwithstanding anything to the contrary herein, if a payment or benefit under this Agreement is due to a "separation from service" for purposes of the rules under Treas. Reg. § 1.409A-3(i)(2) (payments to specified employees upon a separation from service) and Executive is determined to be a "specified employee" (as determined under Treas. Reg. § 1.409A-1(i)), such payment shall, to the extent necessary to comply with the requirements of Section 409A of the Code, be made on the later of (x) the date specified by the foregoing provisions of this Agreement or (y) the date that is six (6) months after the date of Executive's separation from service (or, if earlier, the date of Executive's death).  Any installment payments that are delayed pursuant to the provisions of this section shall be accumulated and paid in a lump sum on the first day of the seventh month following Executive's separation from service (or, if earlier, upon Executive's death) and the remaining installment payments shall begin on such date in accordance with the schedule provided in this Agreement.   To the extent permitted by Section 409A, each payment hereunder shall be deemed to be a separate payment for purposes of Section 409A of the Code. Notwithstanding the foregoing, to the extent this Agreement (or any provision of this Agreement) is determined not to be compliant with Section 409A of the Code, the Company shall not be liable for any resulting taxes to be paid by Executive.


7.06. Amendments.  No amendment or modification of the terms of this Agreement shall be valid unless made in writing and signed by both Executive and Employer.


7.07. Severability; Reformation.  Whenever possible, each provision of this Agreement shall be interpreted in such a manner as to be effective and valid under applicable Law but if any provision of this Agreement is held to be invalid, illegal or unenforceable under any applicable Law or rule, the validity, legality and enforceability of the other provisions of this Agreement will not be affected or impaired thereby.  If any provision of this Agreement is found invalid, illegal or unenforceable because it is too broad in scope, too lengthy in duration or violates any Law or regulation, it shall be reformed by limiting its scope, limiting its duration or construing it to avoid such violation (as the case may be) while giving the greatest effect to the intent of the parties as is legally permissible.


7.08. No Waiver.  No waiver of any provision of this Agreement shall in any event be effective unless the same shall be in writing and signed by the party against whom such waiver is sought to be enforced, and any such waiver shall be effective only in the specific instance and for the specific purpose for which given.


7.09. Assignment; No Third Party Beneficiary.  This Agreement is a personal service contract, and shall not be assignable by Executive.  This Agreement shall be assignable by Employer to any affiliate of Employer without the written consent of the Executive. This Agreement shall be assignable by Employer to any successor to the business of Employer, without the written consent of Executive; provided, however, that the assignee or transferee is the successor to all or substantially all of the business assets of Employer and such assignee or transferee expressly assumes all the obligations, duties, and liabilities of Employer set forth in this Agreement.  Any purported assignment of this Agreement in violation of this Section 7.09 shall be null and void.  This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns, and no other Person shall have any right, benefit or obligation hereunder.


7.10. Counterparts; Facsimile Signatures.  This Agreement may be executed in separate counterparts, each of which will be an original and all of which taken together shall constitute one and the same agreement, and any party hereto may execute this Agreement by signing any such counterpart.  A facsimile signature by any party on a counterpart of this Agreement shall be binding and effective for all purposes.  Such party shall subsequently deliver to the other party an original, executed copy of this Agreement; provided, however, that a failure of such party to deliver an original, executed copy shall not invalidate Executive's  or its signature.


7.11. Notices.  All notices and other communications relating to this Agreement will be in writing and will be deemed to have been given when personally delivered, three (3) days following mailing by certified or registered mail, return receipt requested, and one (1) Business Day following delivery to a reliable overnight courier or immediately following transmission by electronic facsimile.
