The amount of each annual bonus shall be determined by Company at its discretion; provided, that, your target bonus for each year of the

Term shall be $800,000 (or a pro rata portion of such amount for a portion of a year), based on the strength of your performance and on the performance of Company.”

6. Paragraph 7 of the Agreement is hereby amended in its entirety to read as follows:

“13. Termination by You for Good Reason; Consequences of Breach by Company or Non-renewal:

(a) Termination by You for Good Reason: (i) For purposes of this Paragraph 13(a), Company shall be in breach of its obligations to you hereunder if there shall have occurred any of the following events (each such event being referred to as a “Good Reason”): (A) a change in your title and position shall have been put into effect such that you are no longer either Chairman & CEO of Warner/Chappell Music or Executive Vice President and General Counsel of Company; (B) you shall have been required to report to anyone other than as provided in Paragraph 6 hereof; (C) any monies required to be paid to you hereunder shall not be paid when due; (D) Company assigns its rights and obligations under this Agreement in contravention of the provisions of Paragraph 18(e) below or (E) Company requires you to relocate your primary residence outside the greater Los Angeles or New York metropolitan area (if you are serving as the Chairman & CEO of Warner/Chappell Music) or the greater New York metropolitan area (if you are serving as the Executive Vice President and General Counsel of Company) in order to perform your duties to Company hereunder.

(ii) You may exercise your right to terminate the Term of this Agreement for Good Reason pursuant to this Paragraph 13(a) by notice given to Company in writing specifying the Good Reason for termination within sixty (60) days after the occurrence of any such event constituting Good Reason, otherwise your right to terminate this Agreement by reason of the occurrence of such event shall expire and shall be deemed to have permanently lapsed. Any such termination in compliance with the provisions of this Paragraph 13(b) shall be effective thirty (30) days after the date of your written notice of termination, except that if Company shall cure such specified cause within such thirty-day period, you shall not be entitled to terminate the term of this Agreement by reason

of such specified Good Reason and the notice of termination given by you shall be null and void and of no effect whatsoever.

(b) In the event of a “Special Termination” (as defined below) of your employment, your sole remedy shall be that, upon your execution of a Release (as defined below) Company shall promptly pay to you the “Special Termination Payments” (as defined below), and in the event of a “Qualifying Non-renewal” (as defined below), your sole remedy shall be that, upon your execution of a Release, Company shall pay to you the “Non-renewal Payments” (as defined below).

(c) The “Basic Termination Payments” shall mean any accrued but unpaid salary, awarded but unpaid annual bonuses, accrued vacation pay in accordance with Company policy, any unreimbursed expenses pursuant to Paragraph 8, plus any accrued but unpaid benefits in accordance with Paragraph 9, in each case to the date on which your employment terminates pursuant to an event described in subparagraph (e) or (g), below, as applicable (the “Termination Date”).

(d) A “Release” shall mean a release agreement in Company’s standard form, attached hereto as Exhibit A.

(e) A “Special Termination” shall have occurred in the event that (i) Company terminates your employment hereunder other than pursuant to Paragraphs 11 or 12 hereof or (ii) you terminate this Agreement for Good Reason in accordance with Paragraph 13(a).

(f) “Special Termination Payments” shall mean (i) the Basic Termination Payments; plus (ii) the greater of (A) the “Severance Amount” (as defined below) and (B) the sum of (I) $1,500,000, plus (II) an amount equal to $800,000 multiplied by a fraction, the numerator of which is the number of days in the period beginning on the first day of the fiscal year in which your termination occurs and ending on the date of your termination, and the denominator of which is 365.

(g) A “Qualifying Non-renewal” shall have occurred in the event that, at the end of the Term: (i) Company declines to offer you continued employment with Company or one of its affiliates; or (ii) Company offers you continued employment with Company or one of its affiliates at salary or target bonus lower than your salary or target bonus as in effect on the last day of the Term, or containing severance provisions less favorable to you than the severance provisions set out in this paragraph 13, and you elect to decline such offer and terminate your employment with Company.

(h) The “Non-renewal Payments” shall mean (i) the Basic Termination Payments; plus (ii) the greater of (A) the amount of severance pay (the

“Severance Amount”) that would have been payable to you under Company policy as in effect on the Termination Date had you not been subject to an employment agreement with Company and (B) the sum of (I) $1,500,000 plus (II) an amount equal to $800,000 multiplied by a fraction, the numerator of which is the number of days in the period beginning on the first day of the fiscal year in which your employment terminates and ending on the date on which your employment terminates, and the denominator of which is 365.

(i) Any Termination Payments payable to you under Paragraph 11(f) or (h) above shall be made by Company in accordance with its regular payroll practices by means of continued payments to you (i) of your salary at the same rate as was in effect as of the Termination Date for the applicable period as is necessary to cause the full amount due under such clause to be paid, or (ii) of salary for such other period as Company determines is necessary to prevent such amount from being deemed “deferred compensation” under applicable tax law; provided that in the event that the Payment Period is so modified, your rate of pay during such period shall be modified accordingly in order to cause the payment in full of the amounts required to be paid to you pursuant to this Paragraph 13 (the “Payment Period”). During the Payment Period, Company shall continue to provide you with coverage under Company’s medical plans in accordance with the terms of such plans, and you shall be entitled to no other benefits during such period.

(j) In the event you elect not to execute and deliver a Release in connection with a Special Termination or a Qualifying Non-renewal, Company shall only be obligated to pay to you the Basic Termination Payments. Following the delivery of an executed Release pursuant to this Paragraph 13, you shall have no duty to seek substitute employment, and Company shall have no right of offset against any amounts paid to you under this Paragraph 13 with respect to any compensation or fees thereafter received by you from any employment thereafter obtained or consultancy arrangement thereafter entered into by you.”

8. Paragraph 18(g) of the Agreement is hereby amended in its entirety to read as follows:

(g) This Agreement shall be governed by and construed according to the laws of the State of New York as applicable to agreements executed in and to be wholly performed within such State.

Except as expressly amended herein, the terms and provisions of the Agreement shall remain in full force and effect.

If the foregoing correctly sets forth our understanding, please sign below and return this agreement to Company.
