Exhibit 99(3) AGREEMENT, dated as of February 5, 1999, among TheBetterPlan ("TBP"), Inc., a Florida corporation ("Buyer"), and the holders (the "Stockholders") of the shares of common stock, $0.01 par value (the "Shares") of Computer Management Sciences, Inc., a Florida corporation (the "Company"), listed on the signature pages hereof. In order to induce Buyer and certain of its affiliates to enter into an agreement and plan of merger (the "Merger Agreement") with the Company, Buyer has requested the Stockholders, and the Stockholders have agreed, to enter into this Agreement. The parties hereto agree as follows: ARTICLE I STOCK OPTION SECTION 1.1. GRANT OF STOCK OPTION. Each of the Stockholders hereby grants to Buyer an irrevocable option (the "Option") to purchase the number of shares opposite such Stockholder's name on the signature pages hereto and any additional Shares acquired by such Stockholder in any capacity (whether by exercise of options, warrants or rights, the conversion or exchange of convertible or exchangeable securities or by means of a purchase, dividend, distribution or otherwise) (such "Stockholder's Shares" and, collectively, the "Stockholder Shares") at a purchase price of $28.00 per Stockholder Share (as adjusted pursuant to Section 1.6, the "Purchase Price"). With respect to each Stockholder, such Stockholder's Shares do not include Shares held pursuant to (i) the Company's Employee Stock Ownership Plan and Trust (the "ESOP") created pursuant to the Trust Agreement, dated as of November 17, 1989, between the Company and the trustee thereof or (ii) the Company's Profit Sharing-401(k) Plan dated December 30, 1994 (the "401(k) Plan"). SECTION 1.2. EXERCISE OF OPTION. (a) Subject to the conditions set forth in Section 1.5 hereof, the Option may be exercised by Buyer, in whole or in part, at any time or from time to time after the date hereof and prior to the 30th business day after the termination of the Merger Agreement in accordance with the terms thereof. In the event Buyer wishes to exercise the Option for all or some of the Stockholder Shares other than pursuant to the Offer (as defined in the Merger Agreement), Buyer shall send a written notice (the "Exercise Notice") to the Stockholders specifying the total number of Stockholder Shares it wishes to purchase pursuant to such exercise (and the corresponding number of each such Stockholder's Shares) and the place, the date (not less than one nor more than 20 business days from the date of the Exercise Notice) and the time for the closing of such purchase, provided that such date and time may be earlier than one day after the Exercise Notice if reasonably practicable. Each closing of a purchase of Stockholder Shares pursuant to this Section 1.2(a) (a "Closing") shall take place at the place, on the date and at the time designated by Buyer in its Exercise Notice, provided that if, at the date of the Closing herein provided for, the conditions set forth in Section 1.5 shall not have been satisfied (or waived), Buyer may postpone the Closing until a date within five business days after such conditions are satisfied. (b) Except to the extent otherwise provided in Section 1.2(c) below, Buyer shall not be under any obligation to deliver any Exercise Notice and may allow the Option to terminate without purchasing any Stockholder Shares hereunder; provided however that once Buyer has delivered to the Stockholders an Exercise Notice, subject to the terms and conditions of this Agreement, Buyer shall be bound to effect the purchase as described in such Exercise Notice. (c) Buyer agrees that, if Buyer shall have accepted Shares for payment and purchased Shares pursuant to the Offer, Buyer shall, within ten business days of such purchase, exercise the Option in its entirety (or any remaining portion of the Option). SECTION 1.3. CLOSING. At the Closing, (a) each Stockholder shall deliver to Buyer (in accordance with Buyer's instructions) a certificate or certificates (the "Certificates") representing all of such Stockholder's Shares, duly endorsed or accompanied by stock powers duly executed in blank and (b) Buyer shall deliver to such Stockholder a certified or bank cashier's check or checks payable to or upon the order of such Stockholder in an amount equal to (i) the number of such Stockholder's Shares being purchased at such Closing multiplied by (ii) the Purchase Price (the "Purchase Amount"). SECTION 1.4. AGREEMENT TO TENDER. Each of the Stockholders hereby agrees to validly tender (or cause the record owner of such shares to validly tender) upon the request of Buyer such Stockholder Shares. Upon receipt of instructions from the Buyer, each Stockholder shall deliver to the depositary (the "Depositary") designated in the Offer (i) a letter of transmittal with respect to such Stockholder's Shares complying with the terms of the Offer together with instructions directing the Depositary to make payment for such Shares directly to the Stockholder (but if such Shares are not accepted for payment or are withdrawn and are to be returned pursuant to the Offer, to return such Shares to such Stockholder whereupon they shall continue to be held by such Stockholder subject to the terms and conditions of this Agreement), (ii) the Certificates and (iii) all other documents or instruments required to be delivered pursuant to the terms of the Offer (such documents in clauses (i) through (iii) collectively being hereinafter referred to as the "Tender Documents"). No tender pursuant to this Section 1.4 will excuse any of the obligations of the Stockholders hereunder. SECTION 1.5. CONDITIONS. The obligation of each Stockholder to sell Stockholder Shares at any Closing is subject to the following conditions: (i) The representations and warranties of Buyer contained in Article IV shall be true and correct in all material respects on the date thereof as if made on such date; (ii) All waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the rules and regulations promulgated thereunder (the "HSR Act") applicable to such exercise of the Option shall have expired or been terminated; (iii) There shall be no preliminary or permanent injunction or other order, decree or ruling issued by a court of competent jurisdiction or by a governmental, regulatory or administrative agency or commission, nor any statute, rule, regulation or order -2- promulgated or enacted by any governmental authority, prohibiting or otherwise restraining such exercise of the Option; and (iv) The Buyer shall have commenced the Offer. SECTION 1.6. ADJUSTMENT UPON CHANGES IN CAPITALIZATION OR MERGER. (a) In the event of any change in the Company's capital stock by reason of stock dividends, stock splits, mergers, consolidations, recapitalizations, combinations, conversions, exchanges of shares, extraordinary or liquidating dividends, or other changes in the corporate or capital structure of the Company which would have the effect of diluting or changing the Buyer's rights hereunder, the number and kind of shares or securities subject to the Option and the purchase price per Stockholder Share (but not the total purchase price) shall be appropriately and equitably adjusted so that the Buyer shall receive upon exercise of the Option the number and class of shares or other securities or property that the Buyer would have received in respect of the Stockholder Shares purchasable upon exercise of the Option if the Option had been exercised immediately prior to such event. Each Stockholder shall take such steps in connection with such consolidation, merger, liquidation or other such action as may be necessary to assure that the provisions hereof shall thereafter apply as nearly as possible to any securities or property thereafter deliverable upon exercise of the Option. (b) In the event the consideration per Share to be paid by Buyer pursuant to the Offer is increased, the Purchase Price shall be similarly increased and in the event the Closing hereunder shall have occurred, Buyer shall promptly pay to each Stockholder the product of the amount of such increase in the Purchase Price multiplied by the number of such Stockholder's Shares as to which the Option has been exercised. ARTICLE II GRANT OF PROXY SECTION 2.1. PROXY. Each Stockholder hereby revokes any and all previous proxies granted with respect to such Stockholder's Shares. Each Stockholder, by this Agreement, with respect to such Stockholder's Shares, does hereby constitute and appoint Buyer, or any nominee of Buyer, with full power of substitution, as its true and lawful attorney and proxy, for and in its name, place and stead, to vote each of such Stockholder's Shares as its proxy, at every annual, special or adjourned meeting, or solicitation of consents, of the stockholders of the Company (including the right to sign its name (as stockholder) to any consent, certificate or other document relating to the Company that the law of the State of Florida may permit or require) (i) in favor of the adoption of the Merger Agreement and this Agreement and approval of the Merger and the other transactions contemplated hereby and by the Merger Agreement, (ii) against any proposal for any recapitalization, merger, sale of assets or other business combination between the Company and any person or entity (other than the Merger) or any other action or agreement that would result in a breach of any covenant, representation or warranty or any other obligation or agreement of the Company under the Merger Agreement not being fulfilled, and (iii) in favor of any other matter relating to consummation of the transactions contemplated by the Merger Agreement and this Agreement. Each Stockholder further agrees to cause such Stockholder's -3- Shares that are outstanding and owned by it beneficially to be voted in accordance with the foregoing. The proxy granted by each Stockholder pursuant to this Article II is irrevocable and is granted in consideration of Buyer's entering into this Agreement and the Merger Agreement; PROVIDED, HOWEVER, that such proxy shall be revoked upon termination of this Agreement in accordance with its terms. ARTICLE III REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDERS Each of the Stockholders severally represents and warrants to the Buyer that: SECTION 3.1. VALID TITLE.
