Subject to the terms and conditions of this Agreement, at the Effective Time, Merger Subsidiary shall be merged with and into Landmark in accordance with the provisions of, and with the effects provided in, Subchapter IX of the DGCL. Landmark shall be the surviving corporation (the “Surviving Corporation”) resulting from the Merger and shall continue to be governed by the Laws of the State of Delaware and shall succeed to and assume all of the rights and obligations of Merger Subsidiary and the separate corporate existence of Merger Subsidiary shall cease.

(b) If at any time after the Effective Time of the Merger, the Surviving Corporation shall consider or be advised that any further assignments or assurances in Law or otherwise are necessary or desirable to vest, perfect or confirm, of record or otherwise, in the Surviving Corporation, all rights, title and interests in all real estate and other property and all privileges, powers and franchises of Landmark and Merger Subsidiary, then the Surviving Corporation and its proper officers and directors, in the name and on behalf of Landmark and Merger Subsidiary, shall execute and deliver all such proper deeds, assignments and assurances in Law and do all things necessary and proper to vest, perfect or confirm title to such property or rights in the Surviving Corporation and otherwise to carry out the purpose of this Agreement, and the proper officers and directors of the Surviving Corporation are fully authorized in the name of Landmark and Merger Subsidiary or otherwise to take any and all such action.

SECTION 2.2. Certificate of Incorporation and Bylaws.

(a) The Certificate of Incorporation of Landmark, as in effect immediately prior to the Effective Time of the Merger, shall be the Certificate of Incorporation of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law.

(b) The Bylaws of Landmark, as in effect immediately prior to the Effective Time of the Merger, shall be the Bylaws of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law.

SECTION 2.3. Board of Directors.

(a) At the Effective Time, the Board of Directors of Parent shall be as listed on Exhibit 2.3 attached hereto. The persons named as members of the Board of Directors of Parent

on Exhibit 2.3 shall be named in Parent’s Proxy Statement/Prospectus for the Parent Special Meeting, subject to receipt of the consent of such individuals to be so named.

(b) The Board of Directors of the Surviving Corporation as of the Effective Time shall be as set forth on Exhibit 2.3.

SECTION 2.4. Management.

The principal officers of the Surviving Corporation at the Effective Time shall be as set forth on Exhibit 2.4.

SECTION 2.5. Effect on Capital Stock.

As of the Effective Time of the Merger, by virtue of the Merger and without any action on the part of any holders of Landmark Shares or capital stock of Merger Subsidiary:

(a) Subject to the other provisions of this Section 2.5, each issued and outstanding Landmark Share shall be converted into the right to receive, upon the surrender of the certificate formerly representing such share of Landmark Common Stock, 25 shares of Parent Common Stock (the “Merger Consideration”); provided that in no event shall more than 250,000 shares of Parent Common Stock in the aggregate be issued to the holders of Landmark Shares pursuant to such exchange.

(b) No fractional shares of Parent Common Stock shall be issued in the Merger. A holder of Landmark Shares that would otherwise be entitled to receive a fractional share of Parent Common Stock as a result of the Merger shall be entitled to receive for such fractional share either (i) nothing, if such fractional share is equal to less than 0.5 of a share of Parent Common Stock or (ii) one share of Parent Common Stock if such fractional share is equal to 0.5 or greater of a share of Parent Common Stock. The parties acknowledge that payment of the above described fractional share consideration in lieu of issuing fractional shares was not separately bargained-for consideration but merely represents a mechanical rounding-off for purposes of simplifying the corporate and accounting complexities which would otherwise be caused by the issuance of fractional shares.

(c) Each share of Merger Subsidiary Common Stock issued and outstanding immediately prior to the Effective Time of the Merger will be converted into one share of the common stock, par value $.01 per share, of the Surviving Corporation, and such common stock of the Surviving Corporation issued on that conversion will constitute all of the issued and outstanding shares of capital stock of the Surviving Corporation.

(d) Notwithstanding any provision contained in this Agreement to the contrary, Landmark Shares outstanding immediately prior to the Effective Time of the Merger and held by a holder who has not voted in favor of the Merger or consented thereto in writing and who has demanded appraisal for such shares (“Dissenting Shares”) in accordance with the DGCL (a “Landmark Dissenting Holder”) shall not be converted into a right to receive the Merger Consideration, but shall, from and after the Effective Time, have only such rights as are afforded to the holders thereof by the provisions of Section 262 of the DGCL, unless such Landmark Dissenting Holder fails to perfect or withdraws or otherwise loses such Landmark Dissenting

Holder’s right to appraisal. If, after the Effective Time of the Merger, such Landmark Dissenting Holder fails to perfect or withdraws or loses such Landmark Dissenting Holder’s right to appraisal, such shares shall be treated as if they had been converted as of the Effective Time of the Merger into a right to receive the Merger Consideration payable in respect of such shares pursuant to Section 2.5(a). Landmark shall give Parent prompt notice of (i) any demands received by Landmark for appraisal of shares, withdrawals of such demands, and any other instruments served pursuant to the DGCL and received by Landmark and (ii) all negotiations and proceedings with respect to such demands. Landmark shall not, except with the prior written consent of Parent, make any payment with respect to any demands for appraisal, or offer to settle, or settle any such demands. If any payments by Landmark are made to Landmark Dissenting Holders with respect to demands for appraisal of Dissenting Shares, then the Parent Common Stock otherwise issuable in exchange for such Dissenting Shares pursuant to Section 2.5(a). shall be issued to the remaining holders of Landmark Shares on a pro rata basis; provided that (i) in no event shall more than 250,000 shares of Parent Common Stock in the aggregate be issued to the holders of Landmark Shares, (ii) after such payment and the payment to Third Security, LLC set forth below (or reserves for one or more of them), as of the Effective Time Landmark shall have at least $200,000 of cash and cash items (the “Minimum Cash”).

(e) Landmark will not, without the prior written consent of Parent, make any payment to Landmark Dissenting Holders (or incur any legal fees or expenses) which would, on a pro forma basis (after reserves) cause it to have less than the Minimum Cash as of the Effective Time.

(f) If Parent makes any cash payment with respect to Landmark Dissenting Shareholders (or incurs any legal expenses in connection therewith), then the shares of Parent Common Stock that would have been issuable to such Landmark Dissenting Shareholders shall be retained by Parent.

SECTION 2.6. Exchange of Common Certificates.

(a) On or before the Effective Time of the Merger, Parent shall mail to each holder of record of a certificate or certificates that immediately prior to the Effective Time of the Merger represented outstanding shares of Landmark Common Stock (the “Common Certificates”), other than Parent, Landmark and any wholly owned Subsidiary of Landmark or Parent, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Common Certificates shall pass, only upon receipt of the Common Certificates by Parent and shall be in a form and have such other provisions as Parent may reasonably specify) and (ii) instructions for use in effecting the surrender of the Common Certificates in exchange for the Merger Consideration. Upon surrender of a Common Certificate to Parent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by Parent, (i) the holder of such Common Certificate shall receive from Parent, as soon as reasonably practicable, the Merger Consideration payable with respect to the number of shares of Landmark Common Stock represented by such Common Certificate and (ii) the Common Certificate so surrendered shall forthwith be canceled. If any shares of Parent Common Stock that a holder of a Common Certificate has a right to receive are to be issued to a Person other than the Person in whose name such Common Certificate so surrendered is registered, it shall be a condition of exchange that

such Common Certificate shall be properly endorsed or otherwise in proper form for transfer and that the Person requesting such exchange shall pay any transfer or other taxes required by reason of the exchange to a Person other than the registered holder of such Common Certificate or establish to the reasonable satisfaction of Parent that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.6, each Common Certificate shall be deemed as of the Effective Time of the Merger to represent only the right to receive, upon surrender of such Common Certificate in accordance with this Section 2.6(a), Merger Consideration.

(b) No dividends or other distributions declared or made after the Effective Time of the Merger with respect to the Parent Common Stock shall be paid to the holder of any unsurrendered Common Certificate with respect to the Parent Common Stock represented thereby. No shares of Parent Common Stock with respect to Landmark Common Stock shall be paid to any Person until the holder of record of the Common Certificate representing the right to receive such shares of Parent Common Stock shall have been surrendered in accordance with Section 2.6(a).

(c) All shares of Parent Common Stock issued upon the surrender of Common Certificates in accordance with the terms of this Article II, together with any dividends payable thereon to the extent contemplated by this Section 2.6, shall be deemed to have been exchanged and paid in full satisfaction of all rights pertaining to the Landmark Common Stock theretofore represented by such Common Certificates and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Landmark Common Stock that were outstanding immediately prior to the Effective Time of the Merger. If, after the Effective Time of the Merger, Common Certificates are presented to Parent for any reason, they shall be canceled and exchanged as provided in this Article II.

(d) Neither Parent nor Landmark nor any of their Subsidiaries shall be liable to any holder of Landmark Shares or Parent Common Stock, as the case may be, for such shares (or dividends or distributions with respect thereto) delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(e) Parent or the Surviving Corporation shall be entitled to deduct and withhold, or cause the exchange agent, if any, to deduct and withhold, from consideration otherwise payable pursuant to this Agreement to any Landmark Stockholder such amounts as are required to be deducted and withheld with respect to the making of such payment under the Code, or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld, (i) such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Common Certificates in respect of which such deduction and withholding was made, and (ii) Parent shall provide, or cause its exchange agent to provide, to the holders of such securities written notice of the amounts so deducted or withheld.

SECTION 2.7. Appointment of Stockholders’ Representative

(a) The Landmark Stockholders hereby irrevocably appoint ▇▇▇▇▇▇ ▇. ▇▇▇▇ as the Stockholders’ Representative to act as the agent of such stockholders with respect to, and with the full power to resolve, all questions, disputes, to authorize the payments of amounts for expenses, to defend, negotiate and/or settle such claims, to employ such agents, consultants and

professionals, to delegate authority to his agents, and to take such actions, to grant such consents and waivers and execute such documents on their behalf in connection with this Agreement as the Stockholders’ Representative, in his sole discretion, deems best and to perform all of the functions of the Stockholders’ Representative under this Agreement.

(b) Parent may rely upon written directions and notices received from the Stockholders’ Representative with respect to the matters described herein. In the event ▇▇▇▇▇▇ ▇. ▇▇▇▇ ceases to be able to perform his duties as a Stockholders’ Representative as a result of his death, incapacity or resignation, the former Landmark Stockholders (voting in proportion to each stockholder’s former holdings of Landmark Shares as of the Effective Time) shall designate an individual to serve as his successor and to assume all of his duties and obligations as a Stockholders’ Representative hereunder and shall so notify Parent in writing of any such designation. The parties acknowledge and agree that ▇▇▇▇▇▇ ▇. ▇▇▇▇, or any successors designated pursuant to this Section 2.7, is acting as the Stockholders’ Representative for the stockholders of Landmark for the limited administrative purposes set forth herein and nothing in this Agreement is intended to, nor shall, impose any personal liability on ▇▇▇▇▇▇ ▇. ▇▇▇▇ or any other Person who serves as Stockholders’ Representative. At any time, Landmark Stockholders who held immediately prior to the Effective Time a majority of the Landmark Shares may remove or replace the person serving as the Stockholders’ Representative and name a substitute for such person by written notice to Parent.

(c) The Stockholders’ Representative shall not be liable for any act done or omitted in such capacity while acting in good faith, except for any act done or omitted which constitutes gross negligence or willful misconduct. Any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith and of the absence of gross negligence or willful misconduct.

(d) Each of the Landmark Stockholders hereby agrees, jointly and severally, to indemnify, defend and forever hold the Stockholders’ Representative harmless, from and against any and all losses, demands, causes of action, judgments, liabilities, claims, costs, damages and expenses (including, without limitation, fines, forfeitures, reasonable attorneys’ fees, disbursements and administrative or court costs) directly or indirectly arising out of, resulting from, or in connection with, any claim or alleged claim with respect to the Stockholders’ Representative’s obligations under this Agreement or any other agreement contemplated hereby or thereby, except for claims or alleged claims arising out of the gross negligence or willful misconduct of the Stockholders’ Representative.

(e) Parent shall provide the Stockholders’ Representative with such information and assistance as he may reasonably request, including making employees available on a mutually convenient basis.

SECTION 2.8. Anti-Dilution Provisions.

Except with respect to the 25% Parent Stock Dividend (which has already been taken into account in determining the Merger Consideration), in the event Parent changes the number of shares of Parent Common Stock issued and outstanding prior to the Effective Date as a result of a stock split, stock dividend, recapitalization or similar transaction with respect to the

outstanding Parent Common Stock and the record date therefor shall be prior to the Effective Time, the number of shares of Parent Common Stock constituting the Merger Consideration shall be proportionately adjusted.

REPRESENTATIONS AND WARRANTIES OF LANDMARK

Except as specifically set forth in the disclosure schedule of Landmark attached hereto (the “Landmark Disclosure Schedule”), Landmark represents and warrants to Parent and Merger Subsidiary as follows:

SECTION 4.1. Organization and Authority of Landmark.

Landmark is duly organized, validly existing and in good standing under the laws of the State of Delaware. Landmark has the full corporate power to carry on its Business as it is now being conducted and to own, operate and hold under lease its assets and properties as, and in the places where, such properties and assets now are owned, operated or held. Landmark is duly qualified as a foreign entity to do business, and is in good standing, in each jurisdiction where the failure to be so qualified would have a Material Adverse Effect on Landmark. The copies of the Certificate of Incorporation and Bylaws of Landmark, which have been delivered to Parent, are complete and correct and in full force and effect on the date hereof, and no amendment or other modification has been filed, recorded or is pending or contemplated thereto.

SECTION 4.2. Capitalization.

Landmark’s authorized equity capitalization consists of 50,000 shares of Landmark Common Stock. As of the close of business on the date hereof, 10,000 shares of Landmark Common Stock were issued and outstanding. Such shares of Landmark capital stock constituted all of the issued and outstanding shares of capital stock of Landmark as of such date. All issued and outstanding Landmark Shares have been duly authorized and validly issued and are fully paid and nonassessable, are not subject to and have not been issued in violation of any preemptive rights and have not been issued in violation of any federal or state securities laws. Except as provided in Section 8.2(m) hereof, Landmark has not declared or paid any dividend on, or declared or made any distribution with respect to, or authorized or effected any split-up or any other recapitalization of, any of the Landmark Shares, or directly or indirectly redeemed, purchased or otherwise acquired any of its outstanding capital stock or agreed to take any such action and will not take any such action during the period between the date of this Agreement and the Effective Time. Section 4.2 of the Landmark Disclosure Schedule lists all of the stockholders of Landmark as of the date hereof and sets forth the respective holdings of each such stockholder. There are no outstanding options, warrants, notes, subscriptions or other rights to purchase or acquire any capital stock of Landmark, nor are there any outstanding securities that are convertible into or exchangeable for any capital stock of Landmark. There are no contracts, commitments, understandings, arrangements or restrictions by which Landmark is bound to sell or issue any shares of its capital stock.

SECTION 4.3. Authority Relative to this Agreement; Recommendation.

The execution, delivery and performance of this Agreement and of all of the other documents and instruments required hereby by Landmark are within the corporate power and authority of Landmark. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly and validly authorized and approved by the Board of Directors of Landmark, and no other corporate proceeding on the part of Landmark other than obtaining the Landmark Stockholder Approval is necessary to authorize this Agreement or to consummate the transactions contemplated herein. This Agreement and all of the other documents and instruments required hereby have been or will be duly and validly executed and delivered by Landmark and (assuming the due authorization, execution and delivery hereof and thereof by Parent and Merger Subsidiary) constitute or will constitute valid,

legal and binding agreements of Landmark, enforceable against Landmark in accordance with their respective terms.

(g) by Landmark in the event that Parent fails to file the Certificate of Merger with the Secretary of State of the State of Delaware in accordance with Section 9.2 hereof within 24 hours of the Effective Time, unless the failure to file is the result of (i) the failure of Landmark to satisfy all of the conditions to the consummation of the Merger set forth in Section 8.1 or (ii) the office of the Secretary of State of the State of Delaware being closed, provided that the filing is completed as soon as practicable upon the reopening of such office.

SECTION 9.2. Effect of Termination.

If this Agreement is so terminated and the Merger is not consummated, this Agreement shall forthwith become void and have no effect, without any liability on the part of any party or its directors, officers, employees, agents or stockholders, other than the confidentiality provisions of Section 7.4. Nothing contained in this Section 9.2 shall relieve any party from liability for any breach of this Agreement.

SECTION 9.3. Amendment.

This Agreement and the Certificate of Merger may be amended by action taken by Merger Subsidiary, Landmark and Parent at any time before or after adoption of this Agreement by the stockholders of each of Parent and Landmark; provided, however, that after such stockholder approval no amendment shall be made which under applicable Law requires the approval of such stockholders without the approval of stockholders. This Agreement may not be amended except by an instrument in writing signed on behalf of both of the parties hereto.

SECTION 9.4. Extension; Waiver.

At any time prior to the Effective Time, either party hereto may, to the extent legally allowed, (i) extend the time for the performance of any of the obligations or other acts of the other party hereto, (ii) waive any inaccuracies in the representations and warranties contained herein or in any document, certificate or writing delivered pursuant hereto by the other party hereto or (iii) waive compliance with any of the agreements or conditions contained herein by the other party hereto. Any agreement on the part of any party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. The failure of any party hereto to assert any of its rights hereunder shall not constitute a waiver of such rights.

SECTION 9.5. Procedure for Termination, Amendment, Extension or Waiver.

A termination of this Agreement pursuant to Section 9.1, an amendment of this Agreement pursuant to Section 9.3 or an extension or waiver pursuant to Section 9.4 shall, in order to be effective, require in the case of Parent or Landmark, action by its respective Board of Directors or the duly authorized designee of such Board of Directors.
