Page 6

3. Fixed Producing Fee. $[***] (which will be applicable against any FDAGR (defined below))

4. Contingent Compensation:

a. [***]% of the “Adjusted Accountable Receipts” (i.e., subject to Paragraph E.5 below, “Gross Receipts” remaining after deduction of “Third Party Distribution/Servicing Fees”, “Distribution Costs”, “Negative Cost” and any third-party contingent compensation payable prior to there being Adjusted Accountable Receipts, including box office and awards bonuses) until CBE [***]% (defined below);

b. Escalating to [***]% of “Adjusted Gross Receipts” at CBE [***]% (i.e., subject to Paragraph E.5 below, the point at which “Standard Net Proceeds” are first payable applying a [***]% distribution fee (unless an actual distribution fee is charged by any unaffiliated subdistributor in any particular territory with respect to the Gross Receipts derived by such subdistributor in such territory, in which case such distribution fee shall be included for purposes of such calculation));

c. Escalating to [***]% of Adjusted Gross Receipts at CBE [***]% (i.e., subject to Paragraph E.5 below, the point at which Standard Net Proceeds are first payable applying a [***]% distribution fee (unless an actual distribution fee is charged by any unaffiliated subdistributor in any particular territory with respect to the Gross Receipts derived by such subdistributor in such territory, in which case such distribution fee shall be included for purposes of such calculation));

d. Escalating to [***]% of Adjusted Gross Receipts at CBE [***]% (i.e., subject to Paragraph E.5 below, the point at which Standard Net Proceeds are first payable applying a [***]% distribution fee (unless an actual distribution fee is charged by any unaffiliated subdistributor in any particular territory with respect to the Gross Receipts derived by such subdistributor in such territory, in which case such distribution fee shall be included for purposes of such calculation));

Page 7

e. Escalating to [***]% of Adjusted Gross Receipts after IABE, reduced by an amount equal to the aggregate of all third party contingent compensation (howsoever characterized) payable in connection with the picture from and after IABE until LM’s percentage is reduced to an amount equal to [***]% of Adjusted Gross receipts from and after IABE; provided however, that the dollar amount of LM’s percentage of Adjusted Gross Receipts shall never be less than an amount equal to [***]% of Adjusted Accountable Receipts.

If CBS Films elects, in its sole discretion, to pay a first-dollar Adjusted Gross Receipts participation to any other person (other than a financier and/or distributor) engaged to render services in connection with the picture, then, in lieu of the Contingent Compensation set forth above, LM will be entitled to receive [***]% of first-dollar Adjusted Gross Receipts until CBE [***]%; escalating to [***]% of Adjusted Gross Receipts at CBE [***]%; escalating to [***]% of Adjusted Gross Receipts at CBE [***]%; escalating to [***]% of Adjusted Gross Receipts at CBE [***]%; and escalating to [***]% of Adjusted Gross Receipts after IABE, reduced by an amount equal to the aggregate of all third party contingent compensation (howsoever characterized) payable in connection with the picture from and after IABE until LM’s percentage is reduced to an amount equal to [***]% of Adjusted Gross Receipts from and after IABE (collectively, the “FDAGR”). For the avoidance of doubt, any FDAGR payment to LM is subject to deduction of an amount equal to the Fixed Producing Fee. The FDAGR is subject to automatic reduction (on a pro-rata basis with other FDAGR participants) to stay inside an all-inclusive cap of [***]% of FDAGR, and there will be an overbudget penalty equal to [***]% of all such overbudget amounts deducted from [***]% of the FDAGR participation otherwise payable until such time as the overbudget amount is recouped by CBS Films. LM will be entitled to “recapture” such overbudget withheld amount out of an additional participation equal to [***]% of Adjusted Gross Receipts after CBE [***]%.

The percentages of Adjusted Accountable Receipts and Adjusted Gross Receipts above are consistent with CBS Films’ current general policy/practice for converting an “A+ producer” first-dollar gross

Page 8

receipts back-end precedent. If such general conversion policy/practice changes at CBS Films, then the parties shall discuss in good faith any adjustment to the above-referenced percentages of Adjusted Accountable Receipts and Adjusted Gross Receipts (any such agreed adjustments will apply prospectively — i.e., to subsequently “greenlit” films).

5. Definition: The definition of “Adjusted Accountable Receipts,” “Adjusted Gross Receipts,” “Standard Net Proceeds,” “CBE,” “IABE,” “Gross Receipts,” “Third Party Distribution/Servicing Fees,” “Distribution Costs,” and “Negative Cost,” as well as the over-budget penalty provision set forth in Paragraph 4 above, shall be no less favorable to LM than any definition accorded to third party producers, writers, directors or actors by CBS Films in the 3 years preceding the commencement of the Term. In calculating Adjusted Accountable Receipts, the video royalty shall be [***]%; and all VOD, SVOD; AVOD; FVOD; EST and other similar digital streaming shall be included in gross receipts at [***]% of revenues.

Net merchandising receipts will be defined as gross receipts received by CBS Films less a [***]% administration fee, direct costs (including payments to third parties), third party participations and third party collection fees.

c. Logo Credit.

i. Animated logo credit on screen in the main titles (at the beginning of the picture if CBS Films’ animated logo credit is there, and otherwise at the end of the picture; the order of all animated logos shall be determined by CBS Films (i.e., it may appear after the logo(s) of any financiers and/or distributors, but it must precede the logo of any other non-financing or non-distributing production company entity). Notwithstanding the foregoing, with respect to non-U.S. versions of the picture, if the addition of LM’s animated logo causes there to be more than three (3) animated logos (inclusive of CBS Films’ and any other financiers’ and/or distributors’ logos, but not counting logos to other production companies) on the picture, then CBS Films shall have the right (to be exercised in good faith and consistent with CBS Films’ customary practices for “A+ producers”) to remove LM’s animated logo and replace it with a static logo following the end titles of the picture. CBS Films is not obligated to accord LM an animated logo in any trailers, advertising “spots” or other publicity or promotional materials, but must appear if any third party logo appears (i.e., other than CBS Films’ logo).

ii. LM will be accorded a “bug” logo in the billing block of paid ads where CBS Films’ bug logo also appears.

iii. LM’s animated logo will be the same length (or shorter at LM’s election) as the CBS Films’ animated logo and LM’s “bug” logo will be the same size as CBS Films’ “bug” logo.

LM will have consultation on the initial theatrical advertising campaign and release pattern of the Picture (i) in the U.S. and (ii) in any major foreign territory, solely to the extent CBS Films has an approval or consultation right with respect thereto (if CBS Films only has a consultation right in a major foreign territory, such right will be shared with LM; and if CBS Films has neither an approval nor consultation right in a major foreign territory, then it will ask the applicable subdistributor to accord LM the aforementioned consultation right provided that CBS Films does not guarantee any such consultation right), but CBS Films’ decision shall be final and binding at all times.

10. Progress to Production/Turnaround and Derivative Works. No less favorable terms than those accorded to any other producer or director by CBS Films.

The parties agree that the foregoing will constitute the material terms of the production agreement contemplated in paragraph 12 of the employment agreement. In the event LM elects to provide services as a producer, a formal agreement will be negotiated in good faith and shall contain the above terms and such other provisions as are customary and comparable in agreements of this nature recognizing LM’s experience and his skills and understanding of Employer.

In the event of an Advisor Producer Period termination under 12(g)(iii) of the employment agreement, LM shall be entitled to receive his overhead reimbursement, television guaranteed compensation and network penalty payments for the duration of the Term of this production company agreement, subject to the existing provisions of 12(i).
