1 Exhibit 2.1 Encore Orthopedics, Inc. 8900 Shoal Creek Boulevard Building 300 Austin, Texas 78757 Attention: Nicholas Cindrich, Chairman of the Board of Directors and Chief Executive Officer October 11, 1996 Ladies and Gentlemen: This Letter of Intent describes our understanding as to a proposed transaction pursuant to which Encore Orthopedics, Inc. will conclude a merger ("Merger") with a newly formed subsidiary of Healthcare Acquisition Corp. 1. The Parties. A. Healthcare Acquisition Corp., a Delaware corporation,("Healthcare"). B. HCAC Acquisition Company, a Texas corporation to be formed ("Acquisition Co."), the issued and outstanding capital stock of which will be common stock ("Acquisition Common Stock") owned solely by Healthcare. C. Encore Orthopedics, Inc., a Texas corporation ("Encore"). Encore's authorized capital stock consists of 15,000,000 shares of common stock, $0.01 par value ("Encore Common Stock"), and 5,000,000 shares of Preferred Stock, par value $1.00 ("Encore Preferred Stock"), 1,000,000 shares of which have been designated as Series A Preferred Stock. In addition, Encore has issued warrants and options (including, but not limited to, options under certain stock option plans) that are currently outstanding (collectively, the "Encore Warrants"). All Encore Warrants other than those identified on Exhibit A hereto, are hereinafter referred to as the "Encore Included Warrants," and all the Encore Warrants identified on Exhibit A hereto are hereinafter referred to as the "Encore Excluded Warrants." 2. The Merger. On the effective date ("Effective Date") of the Merger (currently anticipated to occur on or about December 31, 1996), and pursuant to the definitive Merger Agreement ("Merger Agreement") described below, Encore and Acquisition will merge with one another in a statutory merger under Texas law in which Encore will be the surviving entity. Upon consummation of the Merger, the 2 Board of Directors of Healthcare will consist of Joel Kanter, Jay Haft and John Abeles, plus seven additional board members designated by Encore in the Merger Agreement and its officers will be designated by Encore in the Merger Agreement from among its current officers. It is contemplated that, upon consummation of the Merger, Healthcare will change its name to one that includes the "Encore" mark. 3. Conversion of Securities. On the Effective Date, all the Acquisition Common Stock will be converted on a one share-for-one share basis into common stock of the surviving entity, and the surviving entity will become a wholly owned subsidiary of Healthcare. On the Effective Date, the Encore Common Stock, Encore Preferred Stock and Encore Warrants shall be converted as follows: A. Encore Common Stock, Encore Preferred Stock and Encore Included Warrants. (1) Holders of Encore Common Stock and Encore Preferred Stock will receive, upon conversion of those securities in the Merger, shares of Healthcare common stock, $.001par value ("Healthcare Common Stock") and New Healthcare $7.00 Warrants (as described below). Each Encore Included Warrant shall, by virtue of the Merger, cease to be exercisable for Encore Common Stock and shall instead be exercisable for one Unit (as hereinafter defined) for each share of Encore Common Stock for which it was exercisable immediately prior to the Merger. A "Unit" shall be the number of shares of Healthcare Common Stock and New Healthcare $7.00 Warrants into which a share of Encore Common Stock is converted by virtue of the Merger. The total number of shares of Healthcare Common Stock available for issuance upon conversion of the Encore Common Stock and Encore Preferred Stock in the Merger and upon exercise of the Encore Included Warrants ("New Healthcare Common Stock") shall be, collectively, that number of shares of Healthcare Common Stock that is equal to the amount obtained by dividing $40,000,000 by the Per Share Amount (as hereinafter defined). The "Per Share Amount" shall be equal to Healthcare's cash on hand as of the Effective Date (including the amounts held in trust that will be distributed to Healthcare upon consummation of the Merger) divided by the total issued and outstanding Healthcare Common Stock as of the Effective Date (but prior to the Merger). The "New Healthcare $7.00 Warrants" shall be warrants for Healthcare Common Stock at an exercise price of $7.00 per share, and will be exercisable for a period of four years beginning on the Effective Date. The total number of shares of Healthcare Common Stock underlying those certain New Healthcare $7.00 Warrants to be issued in the Merger upon conversion of the Encore Common Stock or Encore Preferred Stock and those certain New Healthcare $7.00 Warrants issuable upon exercise of the Encore Included Warrants, collectively, shall be equal to 15% of the number of shares of New Healthcare Common Stock. (2) An amount of the New Healthcare Common Stock issued in exchange for the Encore Common Stock equal to 10% of all the New Healthcare Common Stock ("Escrow Stock") shall be delivered by certain principal Encore shareholders to be identified in the Merger Agreement to an escrow agent to be appointed by the parties, and shall be held in escrow pending completion 3 of the audit of Encore's financial statements for its fiscal year ending December 31, 1996 ("1996 Financial Statements"). If Encore's sales for 1996 as reflected in the 1996 Financial Statements ("1996 Sales"), are less than $16,200,000, Escrow Stock shall be forfeited to the Company for cancellation and return to the Company's authorized but unissued common stock. The number of shares of Escrow Stock to be so forfeited shall be the amount obtained by dividing (i) the product of 2.22 multiplied by the amount by which 1996 Sales is less than $16,200,000; by (ii) the Per Share Amount. The foregoing calculation shall be made promptly after the audit of the 1996 Financial Statements, and, promptly thereafter, the remaining Escrow Stock will be distributed to its owners. The order of forfeiture of Escrow Stock, and appropriate indemnities and releases from the holders of Escrow Stock, will be set forth in the Escrow Agreement with respect thereto to be entered into at or prior to the Effective Date. (3) The definitive Merger Agreement (described below) shall set forth the precise manner in which the New Healthcare Common Stock and New Healthcare $7.00 Warrants will be converted. Encore shall assure that the number of shares of Healthcare Common Stock and New Healthcare $7.00 Warrants issuable upon exercise of all the Encore Warrants complies with the terms of the Encore Warrants. B. Encore Excluded Warrants. The Encore Excluded Warrants will cease to be exercisable for Encore Common Stock. Each Encore Excluded Warrant shall thereafter be exercisable for one Unit per each share of Encore Common Stock for which it was exercisable immediately prior to the Merger, and the exercise price per Unit shall be the exercise price per share of Encore Common Stock in effect immediately prior to the Merger. The Encore Excluded Warrants and the Encore Included Warrants and the plans, if any, under which they were issued will be amended to the extent necessary to accomplish the foregoing and to reduce the number of options authorized under such plan to those that have been issued as of the Effective Date. 4. Adoption of Stock Option Plan. The Merger Agreement will provide that, upon the Effective Date, Healthcare will adopt one or more Stock Option Plan(s) for employees and such other persons, providing for the issuance of such Healthcare Common Stock options as shall be determined by agreement of the parties and set forth in the Merger Agreement. 5. Definitive Agreement. The transactions contemplated by this Letter of Intent are subject to the execution by all parties of the definitive Merger Agreement superseding this Letter of Intent and providing for the transactions contemplated herein.
