SEPARATION AGREEMENT

This SEPARATION AGREEMENT (“Agreement”) is made and entered into by Gary G. Greenfield (the “Executive”) and Avid Technology, Inc. (“the Company”) as of February 6, 2013.

1. SEPARATION DATE. The Company and the Executive have mutually agreed that the Executive's employment with the Company will terminate effective February 11, 2013 (the “Separation Date”). In furtherance thereof, the Executive hereby resigns (i) his positions as Chairman of the Company’s Board of Directors, Chief Executive Officer and President of the Company and (ii) his employment with the Company and each affiliate of the Company, in each case effective as of the Separation Date. The Executive and the Company each hereby waive any advance notice period which otherwise may have been required in connection with the Executive’s termination of employment. Executive will remain a member of the Company’s Board of Directors (the “Board”) following the Separation Date, subject to the Company’s Certificate of Incorporation and Amended and Restated Bylaws and shall be entitled to cash compensation as an outside director in respect of such service following the Separation Date in accordance with the compensation policy of the Board in effect from time to time; provided that the Executive agrees that he shall not be entitled to an initial director equity grant due to the change in his status to a non-employee member of the Board.

2. ELIGIBILITY FOR SEVERANCE BENEFITS UNDER EXISTING AGREEMENT. The Executive is currently party to an Amended and Restated Executive Employment Agreement with the Company, as amended March 14, 2011 (the "Employment Agreement"). Provided that the Release (as described in Paragraph 3) becomes effective, the parties hereto agree that the termination of the Executive's employment described in Paragraph 1 hereof will be treated as a termination of employment under Section 4.1.4 of the Employment Agreement, which will entitle the Executive to the severance payments and benefits described in Section 4.3.3 of the Employment Agreement (the "Severance Benefits"), which shall be paid or provided in such amounts and in such manner as is described in Paragraph 4 below.

3. EXECUTIVE'S RELEASE OF CLAIMS. Pursuant to the Employment Agreement, in order to receive the Severance Benefits, the Executive is required to execute and not revoke a release in favor of the Company in the form attached hereto as Exhibit A (the “Release”).

The payment in respect of the Executive’s accrued and unused vacation as of the date hereof is $108,000.

(b) Salary Continuation. Following the effectiveness of the Release, the Company shall pay the Executive salary continuation during the twelve (12) month period following the Separation Date as provided in Section 4.3.3(b) of the Employment Agreement, in the aggregate amount of $1,014,000, in accordance with the payment schedule described in Section 4.3.3(b); provided that not more than $510,000 of such amount shall be paid to the Executive with respect to such salary continuation during the six month period immediately following the Separation Date; further provided that any reductions made on account of the foregoing limitation shall be applied to the latest payment(s) during such period and any amounts so reduced shall be paid in the Company’s first payroll period immediately following the expiration of such six month period.

(c) Payment in Respect of Bonuses. The Company shall pay the Executive the sum of $936,000 and of $187,200 (resulting in a total payment of $1,123,200), within ten business days after the Release becomes irrevocable, as provided in Section 4.3.3(c) of the Employment Agreement.

(d) Payment in Respect of Section 4.3.3(d). Following the effectiveness of the Release, the Company shall pay the Executive the amount of $30,000 in full satisfaction of the Company’s obligations set forth in Section 4.3.3(d) of the Employment Agreement.

Except as set forth in this Paragraph 4(f)(i), each other time-vesting stock option award or portion thereof that is unvested as of the Separation Date shall be forfeited on the Separation Date.

(ii) Unvested Time-Vesting Restricted Stock Units. Upon the effectiveness of the Release, the Executive will become vested in (A) 25,000 of the restricted stock units granted to the Executive on February 24, 2012 and (B) an additional 24,610 of the restricted stock units granted to the Executive on February 16, 2011. Except as set forth in this Paragraph 4(f)(ii), each other time-vesting restricted stock unit award or portion thereof that is unvested as of the Separation Date shall be forfeited on the Separation Date.

(iii) Other Equity Awards; Unvested Performance Awards. Each equity or equity-based award held by the Executive which is unvested as of the Separation Date (after giving effect to the provisions of this Paragraph 4(f)), including, without limitation, all unvested awards the vesting of which is contingent upon the attainment of performance goals, shall be forfeited on the Separation Date.

Without limiting the generality of the foregoing, the Executive and the Company agree that the provisions of Sections 4.4, 4.5, Article V, Article VI of the Employment Agreement remain in effect in accordance with their terms. The Executive and the Company further agree that, except with respect to Section 4.4 and 4.5 of the Employment Agreement, the provisions of this Agreement supersede the provisions of Article IV of the Agreement and that any entitlement to severance payments or benefits upon or following a termination of the Executive’s employment with the Company shall be solely governed by this Agreement.

6. 409A COMPLIANCE. The Company and the Executive each hereby affirm that it is their mutual view that the provision of payments and benefits described or referenced herein are exempt from or in compliance with the requirements of Section 409A of the Internal Revenue Code of 1986, as amended and the Treasury regulations relating thereto ("Section 409A") and that each party’s tax reporting shall be completed in a manner consistent with such view. The Company and the Executive each agree that upon the Separation Date, the Executive will experience a "separation from service" for purposes of Section 409A.

7. RETURN OF PROPERTY AND COMPANY INFORMATION.
