Manoogian Executive Vice President President 4 September 20, 1985 Mr. Richard G. Mosteller Masco Corporation 21001 Van Born Road Taylor, Michigan 48180 Re: Restricted Stock Incentive Plans Dear Mr. Mosteller: This will confirm (i) our arrangements regarding reimbursement of costs relating to unvested incentive award shares of Masco Corporation ("Masco") common stock and Masco Industries, Inc. ("Industries") common stock upon transfers of employment and consulting relationships between Masco and Industries, (ii) our arrangements regarding reimbursement upon forfeitures of such shares, and (iii) our prior understandings on the implementation of the Stock Repurchase Agreement dated May 1, 1984 between Masco and Industries with respect to Industries' repurchases of its common stock from Masco following the forfeiture of shares of Industries common stock granted under either Masco's or Industries' restricted stock incentive plan (the "Industries Stock Incentive Plans") and following open market repurchases of such stock by Industries. These procedures have been established in order to attribute the cost of such incentive shares in respect of the employees of consultants to Masco and Industries and to permit Masco, among other things, to achieve its expressed objective of maintaining its equity ownership in Industries at not more than 50% after any forfeiture of Industries incentive award shares. These procedures are not intended to alter the rights of the parties under the Corporate Restructuring Plan or the Stock Repurchase Agreement except as expressly provided herein, and may be terminated by Masco or Industries at any time without cause, effective ten days after notice of termination. 5 Mr. Richard G. Mosteller September 20, 1985 Page Two 1. Transfers. If a person changes employment or a consulting relationship from Masco to Industries or from Industries to Masco, the new employer will reimburse the former employer for the cost on the books of the former employer which is associated with unvested shares of Masco common stock or Industries common stock awarded under a Masco or Industries incentive plan, to the extent such shares may continue to vest while the person is engaged by the new employer. 2. Forfeitures By Industries Employees and Consultants. A. Shares of Industries common stock forfeited by an Industries employee or consultant which were granted pursuant to either of the Industries Stock Incentive Plans are deemed automatically acquired by Industries from the employee or consultant as of the date of the forfeiture notwithstanding any contrary provision in either of the Industries Stock Incentive Plans. Industries waives its right under Paragraph 4.02 of the Corporate Restructuring Plan to require Masco to pay Industries an amount equal to the unamortized cost of Industries shares forfeited by Industries employees which were granted under Masco's Industries Stock Incentive Plan and no amount is payable by Industries to Masco on account of Industries' acquisition of such forfeited shares. B. Shares of Masco common stock that were granted under the Masco Restricted Stock Incentive Plan are forfeited by Industries employees and consultants to Masco upon termination of employment or the consulting relationship. Masco will reimburse Industries for the cost on Industries' books which is associated with such forfeited Masco shares. 3. Forfeitures By Masco Employees and Consultants. If Masco's equity ownership in Industries would exceed 50% at the end of any month, shares of Industries common stock forfeited by Masco employees and consultants during such month are deemed automatically acquired by Industries from those employees and consultants (notwithstanding any contrary provision in Masco's Industries Stock Incentive Plan) on the last day of such month to the extent necessary so that Masco's ownership will not exceed 50% as of such date. Industries will reimburse Masco for its loss arising from such forfeiture by paying to Masco an amount equal to the fair market value of such shares (as determined under Paragraph 4 hereof) on the last trading day of such month. 6 Mr. Richard G. Mosteller September 20, 1985 Page Three 4. Repurchase Of Industries Shares On Account of Forfeitures. If Masco's equity ownership in Industries would exceed 50% at the end of any month in which forfeited Industries shares are deemed automatically acquired by Industries, Industries is deemed to repurchase from Masco, on the last day of such month, additional shares of Industries common stock to the extent necessary so that Masco's ownership of Industries common stock does not exceed 50% as of the last day of such month. Pursuant to Paragraph 2(b) of the Stock Repurchase Agreement, the price for the Industries shares so repurchased from Masco is the fair market value of such shares at the close of trading on the last trading day of such month (which is determined by the last sale price for Industries shares as reported in the NASDAQ National Market System). 5. Repurchase of Industries Shares On Account Of Open Market Purchases. If Masco's equity ownership in Industries would exceed 50% at the end of any month in which Industries makes open market purchases of its common stock in connection with awards of shares under its Industries Stock Incentive Plan or in connection with employee stock options, Industries is deemed to repurchase from Masco, on the last day of such month, shares of Industries common stock to the extent necessary so that Masco's ownership of Industries common stock does not exceed 50% as of the day of such month. Notwithstanding Paragraph 2(a) of the Stock Repurchase Agreement, the price for the Industries shares so repurchased from Masco is the weighted average price paid by Industries for its open market share purchases during such month. If Masco's equity ownership of Industries would exceed 50% at the end of any month in which forfeited Industries shares are deemed automatically acquired by Industries and in which Industries makes open market purchases of the types contemplated under Paragraph 5 hereof, shares shall be deemed to be repurchased by Industries first pursuant to paragraph 4. If, after such repurchases pursuant to paragraph 4, Masco's equity ownership would still exceed 50%, shares shall then be deemed to be repurchased by Industries pursuant to this Paragraph 5. 6. Quarterly Settlement. Masco and Industries will effect a quarterly settlement of the amounts required hereunder to be (i) reimbursed upon the transfer of employment or a consulting relationship between Masco and Industries, (ii) reimbursed to Masco upon the forfeiture of Industries shares by Masco employees and consultants, (iii) reimbursed to Industries upon the forfeiture of Masco shares by Industries employees and consultants, and (iv) paid to Masco for any repurchase of Industries shares pursuant to Paragraphs 4 and 5 hereof. 7 Mr. Richard G. Mosteller September 20, 1985 Page Four 7. Additional Provisions. A. Appropriate instructions will be given to Industries' transfer agent to reflect Industries' ownership of forfeited Industries shares and repurchase of additional Industries shares. B. Masco and Industries will promptly notify each other of forfeitures of shares which are subject to these procedures. C. These procedures are deemed to be effective as of May 1, 1984, notwithstanding the fact that certain reports prepared prior to the date hereof are inconsistent herewith, and this letter supersedes any prior arrangements with respect to such procedures. Please confirm your agreement with the foregoing procedures. Sincerely, /s/James J. Sigouin James J. Sigouin Vice President - Finance Confirmed by Masco Corporation: By /s/Richard G. Mosteller Richard G.
