INC., a Florida corporation and a wholly owned subsidiary of Parent (“Acquisition Sub”) and TYLER TECHNOLOGIES, INC., a Delaware corporation (“Shareholder”), a shareholder of Lake, a Florida corporation (the “Company”).

WITNESSETH:

WHEREAS Parent, Acquisition Sub and the Company are entering into an Agreement and Plan of Merger, dated as of the date hereof (as it may be amended from time to time, the “Merger Agreement”; capitalized terms used and not otherwise defined in this Agreement have the respective meanings ascribed to such terms in the Merger Agreement), pursuant to which (i) Acquisition Sub shall commence a cash tender offer (as such tender offer may hereafter be amended from time to time in accordance with the Merger Agreement, the “Offer”) to acquire all of the issued and outstanding shares of common stock, par value $0.01 per share, of the Company (“Common Stock”) in exchange for $7.00 per share in cash (the “Offer Price”) in accordance with and subject to the terms and conditions of the Merger Agreement and the Offer; and (ii) following consummation of the Offer, Acquisition Sub shall merge with and into the Company (the “Merger”);

WHEREAS, Shareholder is the record or beneficial owner of 5,618,952 shares of Common Stock (all such shares of Common Stock and any shares of Common Stock hereafter acquired by such Shareholder, the “Shares”); and

WHEREAS, Shareholder desires to participate in the Offer by tendering the Shares pursuant to the terms and conditions of the Offer Documents and this Agreement in exchange for its receipt of the Offer Price for each of its Shares.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements contained herein, and intending to be legally bound hereby, the parties hereto agree as follows:

ARTICLE I

TENDER OF SHARES

SECTION 1.01  Tender of Shares.    The Shareholder hereby agrees, from and after the date hereof and until the earlier of (x) the acceptance of Shareholder’s Shares on the Offer Closing Date, (y) the Effective Time or (z) the termination of the Merger Agreement pursuant to its terms (such earlier date, the “Termination Date”) to promptly (and, in any event, not later than five (5) business days after commencement of the Offer) tender or cause to be tendered into the Offer, pursuant to and in accordance with the terms of the Offer, and not withdraw or cause to be withdrawn (except following the termination of the Offer in accordance with its terms), all of Shareholder’s Shares. The Shareholder

acknowledges and agrees that Acquisition Sub’s obligation to accept for payment shares of Common Stock in the Offer, including any Shares tendered by the Shareholder, is subject to the terms and conditions of the Merger Agreement and the Offer.

ARTICLE II

VOTING AGREEMENT

SECTION 2.01  Voting Agreement.    Shareholder hereby agrees that, from and after the date hereof and until the Termination Date: (a) at any meeting of the shareholders of the Company, however called, it will cause the Shares Shareholder beneficially owns to be counted as present (or absent if requested by Parent or Acquisition Sub) thereat for purposes of establishing a quorum and (b) at any meeting of the shareholders of the Company, however called, and in any action by consent of the shareholders of the Company, Shareholder shall vote (or cause to be voted) all of Shareholder’s Shares (i) in favor of the approval and adoption of the Merger Agreement, the Merger and all the transactions contemplated by the Merger Agreement (but only if the Offer Documents and Merger Agreement are not amended so as to reduce the Offer Price except for adjustments made as contemplated by Section 6.05(a) of this Agreement) and this Agreement and otherwise in such manner as may be necessary to consummate the Merger at the Offer Price; (ii) against any action, proposal, agreement or transaction that would result in a breach of any covenant, obligation, agreement, representation or warranty of Shareholder contained in this Agreement; and (iii) against any action, agreement, transaction (other than the Merger Agreement or the transactions contemplated thereby) or proposal (including any Acquisition Proposal) that could reasonably be expected, to impede, interfere, delay, discourage or adversely affect the the Offer, the Merger or this Agreement. Any vote by Shareholder that is not in accordance with this Section 2.01 shall be considered null and void. The parties acknowledge and agree that the Shareholder does not have voting rights with respect to the Shares under the Florida Business Corporation Act (“FBCA”) and that the provisions of this Section shall only be applicable if, and to the extent that, a court of competent jurisdiction determines that the Shareholder has voting rights with respect to the Shares.

SECTION 2.02  Irrevocable Proxy.    Pursuant to Section 607.0722 of the Florida Business Corporation Act, Shareholder hereby irrevocably constitutes and appoints Parent, Lawrence A. Gross and Richard C. Tarbox (collectively, “Proxy Agents”) from and after the date hereof and until the Termination Date (at which point such constitution and appointment shall automatically be revoked) as Shareholder’s attorney, agent and proxy (such constitution and appointment, the “Irrevocable Proxy”), with full power of substitution, to vote and otherwise act with respect to all Shareholder’s Shares at any meeting of the shareholders of the Company (whether annual or special and whether or not an adjourned or postponed meeting), however called, and in any action by written consent of the shareholders of the Company, on the matters and in the manner specified in Section 2.01. Without limiting the foregoing, in any such vote or other action pursuant to such proxy, neither Parent nor any other person listed in the immediately preceding sentence shall in any event have the right (and such proxy shall not confer the right) to vote against

2

the Merger or to vote to reduce the Offer Price. THIS PROXY AND POWER OF ATTORNEY ARE IRREVOCABLE AND COUPLED WITH AN INTEREST AND, TO THE EXTENT PERMITTED UNDER APPLICABLE LAW, SHALL BE VALID AND BINDING ON ANY PERSON TO WHOM SHAREHOLDER MAY TRANSFER ANY OF ITS SHARES IN BREACH OF THIS AGREEMENT. THIS PROXY AND POWER OF ATTORNEY SHALL BE VALID DURING THE TERM OF THIS AGREEMENT, REGARDLESS OF WHETHER SUCH TERM EXCEEDS ELEVEN (11) MONTHS. Shareholder hereby revokes all other proxies and powers of attorney with respect to all Shareholder’s Shares that may have heretofore been appointed or granted, and no subsequent proxy or power of attorney shall be given (and if given, shall not be effective) by Shareholder with respect to Shareholder’s Shares. All authority herein conferred or agreed to be conferred shall survive the death or incapacity of Shareholder and any obligation of Shareholder under this Agreement shall be binding upon the heirs, personal representatives, successors and assigns of Shareholder. The parties acknowledge and agree that the Shareholder does not have voting rights with respect to the Shares under the FBCA and that the provisions of this Section shall only be applicable if, and to the extent that, Proxy Agents have voting rights with respect to the Shares under the FBCA.

Any assignment prohibited under this Section shall be null and void.

SECTION 6.15  Severability.    Any term or provision of this Agreement that is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction or other authority declares that any term or provision hereof is invalid, void or unenforceable, the parties agree that the court making such determination shall have the power to reduce the scope, duration, area or applicability of the term or provision, to delete specific words or phrases, or to replace any invalid, void or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision.
