Exhibit 10.1

CHANGE OF CONTROL SEVERANCE PLAN

As amended and restated effective December 10, 2008

Introduction

The Board of Directors of Coherent, Inc., a Delaware corporation (“Company”), has evaluated the economic and social impact of an acquisition or other change of control on its key employees.  The Board recognizes that the potential of such an acquisition or change of control can be a distraction to its key employees and can cause them to consider alternative employment opportunities.  The Board has determined that it is in the best interests of the Company and its stockholders to assure that the Company will have the continued dedication and objectivity of its key employees.  The Board believes that the adoption of this amended and restated Plan will enhance the ability of the Company’s key employees’ to assist the Board in objectively evaluating potential acquisitions or other changes of control.

Furthermore, the Board believes a change of control severance plan of this kind will aid the Company in attracting and retaining the highly qualified, high performing individuals who are essential to its success.  The plan’s assurance of fair treatment will ensure that key employees will be able to maintain productivity, objectivity and focus during the period of significant uncertainty that is inherent in an acquisition or other change of control.

Accordingly, the following plan has been developed and is hereby adopted.

ARTICLE III

ELIGIBILITY

3.1                               Participation in Plan.  As of the Effective Date, only Employees who are Non-Officer Vice-Presidents, Officer Vice-Presidents or the Chief Executive Officer shall be Participants in the Plan.  Following the Effective Date, new Officers of the Company shall automatically become Participants in the Plan; provided, however, that new Non-Officer Vice-Presidents shall only become Participants in the Plan if the Board, in its sole discretion, affirmatively determines that they are eligible Participants.  A Participant shall cease to be a Participant in the Plan when he or she ceases to be an Employee of an Employer, unless such Participant is then entitled to payment of a Severance Payment as provided in the Plan.  A Participant entitled to payment of a Severance Payment shall remain a Participant in the Plan until the full amount of the Severance Payment has been paid to the Participant.

ARTICLE IV

SEVERANCE BENEFITS

4.1                               Right to Severance Payment.  A Participant shall be entitled to receive from the Company a Severance Payment in the amount provided in Section 4.3 if there has been a Change of Control of the Company and if, within two (2) years of the Change of Control, the Participant’s employment by an Employer shall terminate for any reason specified in Section 4.2, whether the termination is voluntary or involuntary.  A Participant shall not be entitled to a Severance Payment if termination occurs for reasons not specified in Section 4.2, including (but not limited to) death, voluntary retirement at or after age 65, total and permanent disability, or for Just Cause.

4.2                               Good Reasons for Termination.  Following a Change of Control, and subject to a Participant’s entering into and not revoking a Release of Claims in favor of the Company or any successor company in substantially the form attached hereto as Exhibit A (the “Release”), a Participant shall be entitled to a Severance Payment and to the benefits described in Section 4.5 if his or her employment by an Employer is terminated, voluntarily or involuntarily, following any one or more of the following events:

(a)           The Employer reduces the Participant’s Base Pay as in effect immediately prior to the Change of Control.

(b)           Without the Participant’s express written consent, the Employer requires the Participant to change the location of his or her job or office, so that he or she will be based at a location more than twenty-five (25) miles from the location of his job or office immediately prior to the Change of Control.

(c)           The Employer decreases its cost of Employer-provided benefits, under plans, arrangements, policies and procedures, taken as a whole, compared to the Employer-provided cost of

4

such benefits immediately prior to the Change of Control, or the Employer increases the cost of such benefits to the Participant compared to the Participant cost immediately prior to the Change of Control; provided, however, that if such decrease or increase results from the Employer’s good faith exercise of business judgment or in response to changes in federal or state law, such decrease or increase shall not be a Good Reason for termination.

(d)           The Participant incurs a significant reduction in duties and responsibilities as determined by the Review Committee.

(e)           A successor company fails or refuses to assume the Company’s obligations under this Plan, as required by Article VII.

(f)            The Company or any successor company breaches any of the provisions of this Plan.

(g)           The Employer terminates the employment of a Participant other than for Just Cause.

Provided, however, that such events shall not constitute grounds for a Good Reason termination unless the Participant has provided notice to the Company of the existence of the one or more of the above conditions within 90 days of its initial existence and the Company has been provided at least 30 days to remedy the condition.

4.3                               Amount of Severance Payment.  Each Participant entitled to a Severance Payment under this Plan shall receive from the Company a cash payment as follows:

(a)           Chief Executive Officer.  The Severance Payment for the Company’s Chief Executive Officer shall equal the product of 2.99 times the sum of the Chief Executive Officer’s Base Pay and Bonus Pay.

(b)           Officer Vice-Presidents.  The Severance Payment for the Company’s Officer Vice-Presidents shall equal the product of two times the sum of the Officer Vice-President’s Base Pay and Bonus Pay.

(c)           Non-Officer Vice-Presidents.  The Severance Payment for the Company’s Non-Officer Vice-Presidents shall equal the product of one times the sum of the Non-Officer Vice-President’s Base Pay and Bonus Pay.

(d)           Non-U.S. Participants.  In the case of a Participant who performs all or substantially all of his or her employment services outside of the United States, the Company may, in its discretion, reduce the Severance Payment otherwise calculated under Section 4.3(a), (b) or (c) by the amount of severance-type benefits to which such Participant is then entitled under the laws of the country or countries in which such services are performed.

4.4                               Time of Severance Payment.  Subject to section 4.5(e) hereof, the Severance Payment to which a Participant is entitled shall be paid by the Company to the Participant, in cash and in full, not later than the later of (i) ten calendar days after the termination date or, (ii) two business days

5

following the date of effectiveness of the Release (the “Payment Date”).  If such a Participant should die before all amounts payable to him or her have been paid, such unpaid amounts shall be paid to the Participant’s designated beneficiary, if living, otherwise to the personal representative of the Participant’s estate.

4.5                               Other Severance Provisions.  In the event a Severance Payment obligation is triggered under this Plan for a Participant, such Participant shall also receive the following benefits:

(a)           Equity Compensation Acceleration.  One hundred percent of Participant’s outstanding unvested equity compensation awards shall automatically accelerate their vesting so as to become fully vested and, with respect to stock options and stock appreciation rights, exercisable.

(b)           Health Insurance.  In addition, for a period set forth below, the Company shall be obligated to continue to make available to the Participant and to pay directly or reimburse premiums for Participant and his or her covered dependents within thirty (30) days of the premium due date for all group health, dental, vision and life insurance plans existing on the date of the Participant’s termination at the same level and with the same employee premium cost as provided to such Participant immediately prior to the Participant’s termination (the “Company-Paid Coverage”); provided, however that such payments or reimbursements shall be delayed six months and one day from the date of termination (and then paid in full in arrears) to the extent required to avoid the imposition of additional tax under Internal Revenue Code Section 409A (“Code Section 409A”).  If a Participant’s coverage under such plans coverage included the Participant’s dependents immediately prior to the Participant’s termination, such dependents shall also be covered at Company expense.  Company-Paid Coverage shall continue for three years for the Company’s Chief Executive Officer, for two years for the Company’s Officer Vice-Presidents and for one year for the Company’s non-Officer Vice Presidents.  For purposes of the continuation health coverage required under Section 4980B of the Code (“COBRA”), the date of the “qualifying event” giving rise to a Participant’s COBRA election period (and that of his “qualifying beneficiaries”) shall be the last date on which the Participant receives Company-Paid Coverage under this Plan.

(c)           Outplacement Assistance.  On termination, the Participant shall be entitled to reasonable, pre-approved Company-paid outplacement assistance, including job counseling and referral services.

(d)           Golden Parachute Excise Taxes.

(i)       Chief Executive Officer — Reduction if Parachute Payments Are Less than 3.59 x Base Amount.  In the event that the benefits provided for in this Plan or otherwise payable to the Company’s Chief Executive Officer (a) constitute “parachute payments” within the meaning of Code Section 280G, (b) would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), and (c) the aggregate value of such parachute payments, as determined in accordance with Section 280G of the Code and the Treasury Regulations thereunder is less than the product obtained by multiplying 3.59 by Chief Executive Officer’s “base amount” within the meaning of Code Section 280G(b)(3), then the benefits under this Plan shall be reduced to the extent necessary (but only to that extent) so that no portion of such benefits will be subject to the Excise Tax.

6

(ii)      Chief Executive Officer — Full Excise Tax Gross-Up if Parachute Payments Equal to or Greater than 3.59 x Base Amount.  In the event that the benefits provided for in this Plan or otherwise payable to the Company’s Chief Executive Officer (a) constitute “parachute payments” within the meaning of Code Section 280G, (b) would be subject to the Excise Tax, and (c) the aggregate value of such parachute payments, as determined in accordance with Section 280G of the Code and the Treasury Regulations thereunder is equal to or greater than the product obtained by multiplying 3.59 by the Chief Executive Officer’s “base amount” within the meaning of Code Section 280G(b)(3), then the Chief Executive Officer shall receive (i) a payment from the Company sufficient to pay such Excise Tax, plus (ii) an additional payment from the Company sufficient to pay the Excise Tax and federal and state income and employment taxes arising from the payments made by the Company to its Chief Executive Officer pursuant to this sentence.  The Executive shall receive such payments no later than the end of the Executive’s taxable year following the taxable year in which the Executive remitted the applicable taxes.

(iii)     Best Results Approach for Participants other than Chief Executive Officer.  In the event that the severance and other benefits provided for in this Plan or otherwise payable or provided to a Participant other than the Company’s Chief Executive Officer (i) constitute “parachute payments” within the meaning of Section 280G of the Code, and (ii) but for this Section 4.5(d)(iii), would be subject to the Excise Tax, then the Participant’s Plan benefits shall be either (a) delivered in full, or (b) delivered as to such lesser extent which would result in no portion of such severance benefits being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the Excise Tax, results in the receipt by the Participant on an after-tax basis, of the greatest amount of severance benefits, notwithstanding that all or some portion of such severance benefits may be taxable under Section 4999 of the Code.

(iv)     General 280G.  Unless the Company and Employee otherwise agree in writing, any determination required under this Section 4.5(d) will be made in writing by a national “Big Four” accounting firm selected by the Company or such other person or entity to which the parties mutually agree (the “Accountants”), whose determination will be conclusive and binding upon Employee and the Company for all purposes.  For purposes of making the calculations required by this Section 4.5(d) the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code.  The Company and the Participants shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this Section.  The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section 4.5(d)(iii) Any reduction in payments and/or benefits required by this Section4.5(d) shall occur in the following order: (1) reduction of cash payments; and (2) reduction of equity acceleration (full-value awards first, then stock options), and (3) other benefits paid to Executive.  In the event that acceleration of vesting of equity awards is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of grant for Executive’s equity awards.

7

(e)           Internal Revenue Code Section 409A.

(i)       Notwithstanding anything to the contrary in this Plan, if Participant is a “specified employee” within the meaning of Section 409A of the Code, and the final regulations and any guidance promulgated thereunder (“Section 409A”) at the time of Participant’s separation from service (as such term is defined in Section 409A), then the cash severance benefits payable to Participant under this Agreement, if any, and any other severance payments or separation benefits that may be considered deferred compensation under Section 409A (together, the “Deferred Compensation Separation Benefits”) otherwise due to Participant on or within the six (6) month period following Participant’s separation from service shall accrue during such six (6) month period and shall become payable in a lump sum payment on the date six (6) months and one (1) day following the date of Participant’s separation from service.  All subsequent payments, if any, shall be payable in accordance with the payment schedule applicable to each payment or benefit.  Notwithstanding anything herein to the contrary, if Participant dies following his separation from service but prior to the six (6) month anniversary of his date of separation from service, then any payments delayed in accordance with this Section shall be payable in a lump sum as soon as administratively practicable after the date of Participant’s death and all other Deferred Compensation Separation Benefits shall be payable in accordance with the payment schedule applicable to each payment or benefit.

(f)    It is the intent of this Agreement to comply with the requirements of Section 409A so that none of the severance payments and benefits to be provided hereunder shall be subject to the additional tax imposed under Section 409A, and any ambiguities herein shall be interpreted to so comply.  The Company and Participant agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions which are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition under Section 409A prior to actual payment to Participant.

(g)   Notwithstanding any other provisions of this Agreement, Participant’s receipt of severance payments and benefits under this Agreement is conditioned upon Participant signing and not revoking the Release and subject to the Release becoming effective within sixty (60) days following Participant’s termination of employment (the “Release Period”).  No severance will be paid or provided until the Release becomes effective.  No severance will be paid or provided unless the Release becomes effective during the Release Period.  In the event Participant’s separation from service occurs on or after November 1 of any year, any severance hereunder will be paid in arrears on the first payroll date to occur during the following calendar year, or such later time as required by Section 409A.

ARTICLE V

OTHER RIGHTS AND BENEFITS NOT AFFECTED

benefit, incentive, retirement, stock option, stock bonus, stock purchase plan, or any employment agreement or other plan or arrangement.

5.2           Employment Status.  This Plan does not constitute a contract of employment or impose on the Participant or the Participant’s Employer any obligation to retain the Participant as an Employee, to change the status of the Participant’s employment, or to change the Company’s policies regarding termination of employment.

10.2         An employee or former employee of an Employer who disagrees with their allotment of benefits under this Plan may file a written appeal with the designated Human Resources representative.  Any claim relating to this Plan shall be subject to this appeal process.  If an employee or former employee of an Employer, or their representative (the “Claimant”) submits a written claim for a benefit under the Plan and the claim is denied in whole or in part, the Employer shall provide the Claimant with a written or electronic notification that complies with Department of Labor Regulation Section 2520.104b-1(c)(1).

(c)           Claim Review Procedure.  The Claimant may request review of the denial at any time within sixty (60) days following the date the Claimant received notice of the denial of his or her claim.  The Employer shall afford the Claimant a full and fair review of the decision denying the claim and, if so requested, shall:

(ii)      provide that the Claimant shall be provided, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information (other than documents, records and other information that is legally-privileged) relevant to the Claimant’s claim for benefits; and

(iii)     provide for a review that takes into account all comments, documents, records and other information submitted by the Claimant relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination.

(d)           If the claim is subsequently also denied by the Employer, in whole or in part, then the Claimant shall be furnished with a denial notice that shall contain the following:

(i)       specific reason(s) for the denial;

10.3         If the appeal of an employee or former employee of an employer appeal is denied, such employee or former employee shall have the right and option to elect (in lieu of litigation) to have any dispute or controversy arising under or in connection with the Plan settled by arbitration, conducted before a panel of three arbitrators sitting in a location selected by the employee within fifty (50) miles from the location of his or her job with an Employer, in accordance with rules of the American Arbitration Association then in effect.  Judgment may be entered on the award of the arbitrator in any court having jurisdiction.  All expenses of such arbitration, including the fees and expenses of the counsel for the employee, shall be borne by the Employer.
