Definitions. As used in this Agreement: "Commission" shall mean the Securities and Exchange Commission, or any other federal agency at the time administering the Securities Act. "Common Stock" shall mean the Corporation's $1.00 par value Common Stock. "Person" shall mean and include an individual, a corporation, a partnership, a trust, an unincorporated organization and a government or any department, agency or political subdivision thereof. "Restricted Common Stock" shall mean shares of Common Stock constituting Restricted Securities. "Restricted Securities" shall mean the Shares, including any shares of Common Stock or other securities convertible into or exchangeable for Common Stock or received as a stock dividend or other distribution in respect to any of the foregoing, held by the Stockholder or its successors and assigns evidenced by certificates bearing a restrictive legend prohibiting transfer of such Restricted -1- Securities unless the transfer of the Restricted Securities evidenced thereby is registered under the Securities Act or the transfer complies with an exemption from such registration (a "Restrictive Legend"). "Securities Act" shall mean the Securities Act of 1933, as amended, or any similar federal statute, and the rules and regulations of the Commission thereunder, all as the same shall be in effect at the time. "Transfer" shall include any disposition of any shares of Restricted Securities or of any interest therein which would constitute a sale thereof within the meaning of the Securities Act. 2. Required Registration. If at any time the Corporation shall be requested in writing by the Stockholder, or any holder of not less than 250,000 shares of Restricted Common Stock, to effect the registration under the Securities Act of not less than an aggregate of 250,000 shares of Restricted Common Stock, such request shall be deemed an offer (the "Offer") to sell to the Corporation or its assigns for cash all of the shares of Restricted Common Stock for which registration is requested (the "Offered Securities") at a price equal to the average of the daily "market price" (as hereinafter defined) per share of the Common Stock for the ten consecutive trading days immediately preceding the date of receipt of such request by the Corporation. The "market price" for each trading day shall be the last reported sale price regular way of the Common Stock on the Composite Tape of the New York Stock Exchange on each such trading day upon which such a sale shall have been effected, or if no sale takes place on any such day on such exchange, the average of the closing bid and asked prices on such day as officially quoted on such exchange. The Offer shall remain open for a period of ten calendar days immediately following the date of receipt by the Corporation of the registration request (the "Offer Period"). To accept the Offer, the Corporation or its assigns must give written notice (the "Notice of Acceptance") to the requesting holder prior to the end of the Offer Period of the Corporation's intention to accept the Offer. The Corporation shall purchase from the requesting holder(s), and the requesting holder(s) shall sell to the Corporation, upon the terms of the Offer, the Offered Securities pursuant to the Notice of Acceptance within ten business days after the date that the Notice of Acceptance is received by the requesting holder(s). If the Corporation does not accept the Offer prior to the expiration of the Offer Period, the Corporation shall promptly give written notice of such proposed registration to all other holders of Restricted Securities, including the Stockholder, and thereupon the Corporation shall promptly use its best efforts to effect the registration under the Securities Act of the shares of Restricted Common Stock that the Corporation has been requested to register by any holder in any response received by the Corporation within 30 days after the date of the written notice by the Corporation; provided, however, that the Corporation shall not be obligated to effect any registration under the Securities Act except in accordance with the following provisions: -2- (a) The Corporation shall not be obligated to file any registration statement with respect to Restricted Common Stock if in the opinion of counsel satisfactory to the Corporation and the holder of such securities the proposed transfer may be effected without registration under the Securities Act, and any certificate evidencing the shares so to be transferred need not bear a Restrictive Legend. (b) The Corporation shall not be obligated to effect any registration except at the request of the holder or holders of Restricted Common Stock who shall request registration of Restricted Common Stock then owned or obtainable by them representing in the aggregate not less than 250,000 shares of outstanding Restricted Common Stock. (c) The Corporation shall not be obligated to file and cause to become effective (i) more than two registration statements in which shares of Restricted Common Stock are registered under the Securities Act pursuant to this Section 2 at the request of the Stockholder, or (ii) any registration statement within three months after the effective date of any other registration statement filed by the Corporation relating to any public offering of securities of the Corporation for cash for the Corporation's own account. 3. Incidental Registration. If the Corporation at any time proposes for any reason to register any of its Common Stock under the Securities Act in connection with a proposed offering to the general public, the Corporation shall at such time promptly give written notice to all holders of Restricted Common Stock of its intention to do so, and, upon the written request, received by the Corporation within 30 days after the date of any such notice, of the holders of any Restricted Common Stock to register any shares of Restricted Common Stock, the Corporation shall use its best efforts to cause all such shares of Restricted Common Stock the holders of which shall have so requested registration thereof to be registered under the Securities Act promptly upon receipt of the written request of such holders for such registration, all to the extent necessary to permit the sale or other disposition by the prospective seller or sellers of the shares of Restricted Common Stock so registered. In the event that the proposed registration by the Corporation is, in whole or in part, an underwritten public offering of securities of the Corporation, any request pursuant to this Section 3 to register shares of Restricted Common Stock may specify that such shares are to be included in the underwriting on the same terms and conditions as the shares of Common Stock, if any, otherwise being sold through underwriters under such registration; provided, however, that if the managing underwriter determines and advises the holders thereof in writing that the inclusion of all shares of the Restricted Common Stock and other Common Stock of the Corporation entitled to be included in the registration ("Other Registrable Stock") originally covered by a request for registration would interfere with the successful marketing of such securities, the number of shares of Restricted Common Stock and Other Registrable Stock that may, in the sole discretion of the managing underwriter, be included in the underwritten public offering on behalf of the holders thereof, if any, shall be allocated: first, to the Stockholder, second to the -3- holders of the Restricted Common Stock in proportion, as nearly as practicable, to the respective number of shares of Restricted Common Stock which they had requested to be included in such underwritten public offering and, thereafter, among the holders of the Other Registrable Securities in proportion, as nearly as practicable, to the respective number of shares of Other Registrable Stock which they had requested to be included in such underwritten public offering. 4. Preparation and Filing. If and whenever the Corporation is under an obligation pursuant to the provisions of this Agreement to use its best efforts to effect the registration of any shares of Restricted Common Stock, the Corporation shall, as expeditiously as practicable: (a) prepare and file with the Commission a registration statement with respect to such shares (on Commission Form S-3 to the extent the Corporation is eligible to use Form S-3) and use its best efforts to cause such registration statement to become and remain effective; (b) prepare and file with the Commission such amendments and supplements to such registration statements and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for at least six months (two years to the extent such registration statement was prepared and filed on Form S-3) and to comply with the provisions of the Securities Act with respect to the sale or other disposition of all shares of Restricted Common Stock covered by such registration statement; (c) furnish to each seller such number of copies of a summary prospectus or other prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act and such other documents as such seller may reasonably request in order to facilitate the public sale or other disposition of such shares of Restricted Common Stock; (d) use its best efforts to register or qualify the shares of Restricted Common Stock covered by such registration statement under the securities or blue sky laws of such jurisdictions as each such seller shall reasonably request and do any and all other acts or things that may be necessary or advisable to enable such seller to consummate the public sale or other disposition in such jurisdictions of such shares; (e) notify each seller of shares of Restricted Common Stock covered by such registration statement, at any time when a prospectus relating thereto is required to be delivered under the Securities Act within the appropriate period mentioned in clause (b) of this Section 4, of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and, at the request of any such seller, prepare and furnish to such seller a reasonable number of copies of a -4- supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such shares, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; and (f) file, on a timely basis, all reports and other documents required to be filed by it pursuant to the Securities Exchange Act of 1934. 5. Expenses. The Corporation shall pay all expenses incurred in complying with Sections 2, 3 and 4 hereof, including, without limitation, all registration and filing fees, fees and expenses of complying with securities and blue sky laws, printing expenses, and fees and disbursements of the Corporation's counsel; provided, however, that all underwriting discounts and selling commissions applicable to the Restricted Common Stock covered by any such registration shall be borne by the respective sellers thereof, in proportion to the respective number of shares of Restricted Common Stock sold by each of them. 6. Holdback Agreements. (a) EA and each other holder of Restricted Common Stock agrees not to effect any public sale or distribution of equity securities of the Corporation, or any securities convertible into or exchangeable or exercisable for such securities, during the seven days prior to and during the 90-day period beginning on the effective date of any underwritten registration effected by the Corporation (except as part of such underwritten registration), unless the managing underwriter otherwise agrees. (b) The Corporation agrees not to effect any public sale or distribution of equity securities, or any securities convertible into or exchangeable or exercisable for such securities, during the seven days prior to and during the 90-day period beginning on the effective date of any underwritten registration pursuant to a registration statement in which any shares of Restricted Common Stock are included, unless the managing underwriters otherwise agrees. 7.

In case any such action is brought against an indemnified person, the indemnifying person will be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying person similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such indemnified person, and after notice from the indemnifying person to such indemnified person of its election so to assume the defense thereof, the indemnifying person shall be responsible for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof. 9.
