ARTICLE II

CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

SECTION 2.01 The Merger

At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, Company or the holders of any of the securities referred to in this Section 2.01:

(a) Common Stock. Each share of Company Common Stock (excluding any shares described in Section 2.01(b) and any Dissenting Shares (as defined Section 2.01(d)) issued and outstanding immediately prior to the Effective Time shall cease to be outstanding and shall be converted into and exchanged for the right to receivean amount of cash equal to the Transaction Value divided by the Company Share Amount (subject to the amount to be withheld pursuant to Section 2.03). The aggregate amount of cash payable pursuant hereto is referred to herein as the “Merger Consideration”. All such shares of Company Common Stock shall cease to be outstanding and shall automatically be canceled and retired and shall cease to exist, and each certificate previously evidencing any such shares (each, a “Certificate” and, collectively, the “Certificates”) shall thereafter represent only the right to receive that portion of the Merger Consideration allocable to the shares of Company Common Stock represented by such Certificate. Except as otherwise provided herein or by applicable Law, the holders of Certificates shall cease to have any rights with respect to the shares of Company Common Stock represented by such Certificates except the right to receive that portion of the Merger Consideration allocable to the shares of Company Common Stock represented by such Certificates. Subject to Section

2.03, each Certificate (or, if any such Certificate has been lost, stolen or destroyed, an affidavit in accordance with Section 2.02(d)) shall be exchanged for that portion of the Merger Consideration allocable to the shares of Company Common Stock represented by such Certificate.

(b) Treasury Stock. All shares of capital stock of Company held in the treasury of Company immediately prior to the Effective Time shall be canceled and extinguished without any conversion thereof and no amount shall be delivered or deliverable in exchange therefor.

(c) Merger Sub Stock. Each share of common stock, par value $.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time (“Merger Sub Stock”) shall be converted into and exchanged for one (1) duly and validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation.

(d) Dissenters’ Rights. Notwithstanding anything in this Merger Agreement to the contrary, any issued and outstanding shares of Company Common Stock held by a Person (a “Dissenting Shareholder”) who duly demands appraisal of his shares of Company Common Stock pursuant to the VSCA and complies with all the provisions of the VSCA concerning the right of holders of Company Common Stock to demand appraisal of their shares in connection with the Merger (“Dissenting Shares”) shall not be converted as described in Section 2.01(a) but shall become the right to receive such cash consideration as may be determined to be due to such Dissenting Shareholder in accordance with the VSCA; provided, however, that, to the extent permissible under the VSCA, no such payment shall be made unless and until such Dissenting Shareholder has surrendered to Parent the Certificate representing the shares of Company Common Stock for which payment is being made or, if such Certificate has been lost, stolen or destroyed, an affidavit in accordance with Section 2.02(d). If, however, such Dissenting Shareholder withdraws his demand for appraisal or fails to perfect or otherwise loses his right of appraisal, in any case pursuant to the VSCA, his shares shall be deemed to be converted as of the Effective Time into the right to receive that portion of the Merger Consideration allocable to such shares, without interest, pursuant to Section 2.01(a). Company shall give Parent (i) prompt notice of any demands for appraisal of shares received by Company and (ii) the opportunity to participate in and direct all negotiations and proceedings with respect to any such demands. Except as otherwise required by applicable Law, Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle, offer to settle or otherwise negotiate, any such demands.

SECTION 2.02 Payment Procedure; Cancellation of Certificates

(a) Payment Procedures. At Closing, each Company Shareholder (other than any Company Shareholder who wishes to exercise such shareholder’s rights in accordance with Section 2.01(d)) shall surrender to Parent the Certificate or Certificates representing all of the shares of Company Common Stock owned by such Company Shareholder immediately prior to the Effective Time, together with a letter of transmittal and an IRS Substitute Form W-9 in substantially the form of Exhibit 2.02(a), and any other documents reasonably required by Parent. Upon surrender by a Company Shareholder of one or more Certificates at Closing, such Certificate shall forthwith be canceled and Parent shall promptly deliver to each such Company Shareholder such Company Shareholder’s allocable portion of the Merger Consideration,

calculated pursuant to Section 2.01 (minus the cash withheld pursuant to Sections 2.02(c) (if any) and 2.03(a)) based on the aggregate number of shares of Company Common Stock held by such Company Shareholder, by wire transfer of immediately available funds to an account designated by such Company Shareholder (such account information to be provided to Parent no less than five (5) business days prior to Closing) or, if such amount is less than $500,000, at Parent’s option, by delivery of a bank check payable to such Company Shareholder. Until surrendered in accordance with the provisions of this Section 2.02, after the Effective Time each Certificate shall represent for all purposes only the right to receive that portion of the Merger Consideration allocable to the shares of Company Common Stock represented by such Certificate, without any interest thereon.

(b) No Further Rights in Stock; No Further Ownership Rights in Company Common Stock. The Merger Consideration given upon the surrender for exchange of Certificates in accordance with the terms of Sections 2.01 and 2.02 shall be deemed to have been given (and paid) in full satisfaction of all rights pertaining to the shares of Company Common Stock theretofore represented by such Certificates, and there shall be no further registration of transfer on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock represented by such Certificates which were outstanding immediately prior to the Effective Time. If, after the Effective Time, any such Certificates are presented to Parent or the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article II, except as otherwise provided by Law.

(c) Withholding of Tax. Parent shall be entitled to deduct and withhold from the allocable portion of the Merger Consideration otherwise payable to any Company Shareholder such amounts as Parent (or any Affiliate thereof) is required to deduct and withhold 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 by Parent (or any Affiliate thereof), such withheld amounts shall be treated for all purposes of this Merger Agreement as having been paid to the Person in respect of whom such deduction and withholding was made by Parent (or any Affiliate thereof).

(d) Lost, Stolen or Destroyed Certificates. In the event any Certificate evidencing shares of Company Common Stock shall have been lost, stolen or destroyed, upon the making of an affidavit setting forth that fact by the Person claiming such lost, stolen or destroyed Certificate and, if required by Parent, the granting of an indemnity on reasonable terms (and, if required by Parent, if more than $20,000 is payable by Parent pursuant hereto with respect to any such Certificate, the posting by such Person of a bond in such reasonable amount as Parent may direct) against any claim that may be made against Parent or the Surviving Corporation with respect to such Certificate, Parent shall pay to such Person that portion of the Merger Consideration allocable to the shares represented by such lost, stolen or destroyed Certificate.

(e) No Liability. After the Closing Date, any holder of Company Common Stock who has not presented such holder’s Certificates to Parent for cancellation and exchange shall be entitled to look only to Parent or the Surviving Corporation (subject to abandoned property, escheat or other similar Laws) as general creditors thereof with respect to the payment of any portion of the Merger Consideration that may be payable upon surrender of any Certificates such holder holds, as

determined pursuant to this Merger Agreement, without any interest thereon. Notwithstanding the foregoing, neither Parent nor the Surviving Corporation shall be liable to any holder of a Certificate for any portion of the Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

SECTION 2.03 Escrow Fund; Shareholders’ Representative

(a) Escrow Fund. When making payments of cash to the Company Shareholders in exchange for their shares of Company Common Stock pursuant to Sections 2.01 and 2.02, Parent shall withhold an aggregate of Five Million Dollars ($5,000,000) in cash (the “Escrow Cash”), and at the Closing Parent shall deliver such Escrow Cash to SunTrust Bank as escrow agent (the “Escrow Agent”). The Escrow Cash shall be held pursuant to the provisions of an escrow agreement substantially in the form of Exhibit 2.03(a) (the “Escrow Agreement”) to be executed at Closing. Parent shall withhold the Escrow Cash by reducing the amount of cash otherwise payable to each Company Shareholder pursuant to Sections 2.01 and 2.02 by an amount equal to such Company Shareholder’s Pro Rata Portion of the Escrow Cash. The Escrow Cash shall be delivered to the Company Shareholders only in accordance with the terms of the Escrow Agreement and this Merger Agreement. The Escrow Cash together with any interest earned on the Escrow Cash shall be held as an escrow fund (the “Escrow Fund”) by the Escrow Agent pursuant to the terms of the Escrow Agreement to provide a source of payment, pursuant to the terms of this Merger Agreement and the Escrow Agreement, of amounts, if any, owing to the Parent Indemnified Persons under Section 9.02 and the reimbursement to Parent of amounts owed Parent under Section 5.11 (if any). In the event that the Merger and this Merger Agreement are approved by the requisite vote of the Company Shareholders pursuant to the VSCA, then all Company Shareholders shall, without any further act of any Company Shareholder, be deemed to have consented to and approved (i) the establishment of the Escrow Fund to be used as provided in this Merger Agreement and the Escrow Agreement to provide a source of payment, pursuant to the terms of the Escrow Agreement and this Merger Agreement, for amounts, if any, owing to Parent Indemnified Persons under Section 9.02 and the reimbursement to Parent of amounts owed Parent under Section 5.11 (if any), and (ii) the appointment of the Shareholders’ Representative as the representative under the Escrow Agreement of the Company Shareholders and as the attorney-in-fact and agent for and on behalf of each such Company Shareholder.

(b) Escrow Period. The Escrow Fund shall be held in escrow under the terms of the Escrow Agreement until the second anniversary of the Closing Date (the “Initial Escrow Period”). At the conclusion of the Initial Escrow Period, the Escrow Agent shall disburse all or such portion of the Escrow Fund not theretofore paid to Parent in accordance with the terms of, or subject to a pending claim under, the Escrow Agreement and this Merger Agreement to the Company Shareholders based upon each Company Shareholder’s Pro Rata Portion of the amount to be disbursed. To the extent that any portion of the Escrow Fund is subject to a pending claim under the Escrow Agreement, the Escrow Agent shall retain such portion of the Escrow Fund under the Escrow Agreement until such time as such pending claim is finally resolved (the “Additional Escrow Period”). The Initial Escrow Period, as and if extended by the Additional Escrow Period, is referred to herein as the “Escrow Period”.

(c) Appointment of Shareholders’ Representative. ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ shall, by virtue of the Merger, be appointed attorney-in-fact and authorized and empowered to act, for and on behalf of any or all of the Company Shareholders (with full power of substitution in the premises), in accordance with this Section 2.03(c) (the above named representative, as well as any subsequent representative of the Company Shareholders appointed by the Company Shareholders, being referred to herein as the “Shareholders’ Representative”). The Shareholders’ Representative shall have the authority to (i) execute and deliver the Escrow Agreement as the representative of the Company Shareholders, (ii) review all claims for indemnification asserted by a Parent Indemnified Person pursuant to Section 9.02 and the reimbursement to Parent of amounts owed Parent under Section 5.11 (if any), (iii) authorize the payment or disbursement of funds with respect to or to satisfy all or any portion of any such claims for indemnification asserted by a Parent Indemnified Person pursuant to Section 9.02 and the reimbursement to Parent of amounts owed Parent under Section 5.11 (if any), (iv) dispute, compromise, litigate or settle on behalf of the Company Shareholders any such claims for indemnification asserted by a Parent Indemnified Person pursuant to Section 9.02 and the reimbursement to Parent of amounts owed Parent under Section 5.11 (if any), (v) give and receive all notices required to be given under this Merger Agreement by or to each Company Shareholder, (vi) execute and deliver on behalf of the Company Shareholders any documents or Agreements contemplated by or necessary or desirable in connection with the foregoing, (vii) expend reasonable amounts in connection with the performance of the Shareholders’ Representative’s obligations pursuant to this Section 2.03(c) or to defend himself against any claim arising out of the proper exercise of his authority pursuant hereto and (viii) take such further actions, including coordinating and administering post-closing matters, related to the rights and obligations of the Company Shareholders as are authorized in this Merger Agreement and the Escrow Agreement.

In the event that ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ dies, becomes legally incapacitated or resigns from such position, ▇▇▇▇▇▇▇ ▇▇▇▇▇▇ shall fill such vacancy and shall be deemed to be the Shareholders’ Representative for all purposes of this Agreement. In the event that ▇▇▇▇▇▇▇ ▇▇▇▇▇▇ dies, becomes legally incapacitated or resigns from such position, a successor Shareholders’ Representative shall be elected by the affirmative vote of a majority of the Company Shareholders, with each such Company Shareholder entitled to cast one vote for each share of Company Common Stock held by such Company Shareholder immediately prior to the Closing Date.

The Shareholders’ Representative shall not be liable to any Company Shareholder, Parent, the Surviving Corporation or their respective Affiliates or any other Person with respect to any action taken or omitted to be taken by the Shareholders’ Representative in his role as Shareholders’ Representative under or in connection with this Merger Agreement and the Escrow Agreement unless such action or omission results from or arises out of fraud, gross negligence, willful misconduct or bad faith on the part of the Shareholders’ Representative. The Shareholders’ Representative shall be entitled to rely upon any instrument or writing believed by the Shareholders’ Representative to be genuine and sufficient and properly presented, and shall not be liable to the Company Shareholders, Parent, Merger Sub or the Surviving Corporation for any action taken or omitted to be taken by the Shareholders’ Representative in such reliance.

Parent, Merger Sub and the Surviving Corporation shall be entitled to rely on the appointment of the Shareholders’ Representative pursuant to this Section 2.03(c) and treat such Shareholders’ Representative as the duly appointed attorney-in-fact of each Company Shareholder.

Each Company Shareholder who votes in favor of the Merger and this Merger Agreement, by such vote and without any further action, and each Company Shareholder who receives any portion of the Merger Consideration in connection with the Merger, by acceptance thereof and without any further action, confirms the appointment and authority of the Shareholders’ Representative as set forth in this Section 2.03(c).

(d) Non-Transferability of Escrow Interests. Parent and the Shareholders’ Representative will jointly maintain a ledger to record the interest in the Escrow Fund held by each Company Shareholder. No certificates will be issued to evidence ownership of such interests. Such interests will be nontransferable, except by operation of Law or by will. Such interests will not entitle the Company Shareholder to any voting or dividend rights and will not bear interest (other than the right to receive a proportional amount of any interest earned on the Escrow Cash if such amounts are distributed in accordance with this Merger Agreement and the Escrow Agreement).

SECTION 2.04 Company Option Plan

The Company Stock Options (to the extent not exercised prior to the Effective Time), the Option Plan and any other plan, program or arrangement providing for the issuance or grant of any interest in respect of the capital stock of Company shall be terminated as of the Effective Time, and following the Effective Time no holder of a Company Stock Option nor any participant in any such plan, program or arrangement shall have any right thereunder to (i) acquire capital securities of the Surviving Corporation or of Parent or (ii) receive any other consideration as a result of such termination.

SECTION 6.06 Director Resignations

Company shall deliver to Parent at or prior to the Closing the resignation of each director of Company, effective as of the Effective Time.

SECTION 6.07 Indemnification

(a) To the fullest extent permitted by Law, from and after the Effective Time, Parent shall, and shall cause the Surviving Corporation to, indemnify, defend and hold harmless each Person who is now, or has been at any time prior to the date of this Merger Agreement or who becomes prior to the Effective Time, an officer, director, employee or fiduciary of Company (the “D&O Indemnified Parties”) against any and all losses, claims, damages, costs, expenses (including reasonable attorneys’ fees and expenses), fines, liabilities or judgments or amounts that are paid in settlement with the approval of Parent (which approval shall not be unreasonably withheld or delayed) of or in connection with any actual or threatened claim, action, suit, proceeding or investigation (each a “D&O Claim”) based in whole or in part on or arising in whole or in part out of, or pertaining to (A) the fact that such Person is or was a director, officer, employee or fiduciary of Company and (B) this Merger Agreement or any of the transactions contemplated hereby, in each case regardless of whether such D&O Claim pertains to any matter or fact arising, existing or occurring at or prior to the Effective Time and regardless of whether such D&O Claim is asserted or claimed prior to, or at or after, the Effective Time. Parent, Company and the Surviving Corporation, as the case may be, will pay all expenses of each D&O Indemnified Party in advance of the final disposition of any such D&O Claim to the fullest extent permitted by Law upon receipt of any undertaking contemplated by Section 13.1-699 of the VSCA. Without limiting the foregoing, in the event any such D&O Claim is brought against any D&O Indemnified Party (whether arising before or after the Effective Time), (i) the D&O Indemnified Parties may retain counsel reasonably satisfactory to them and Parent, (ii) Parent shall, and shall cause the Surviving Corporation to, pay all reasonable fees and expenses of such counsel for the D&O Indemnified Parties promptly as statements therefor are received, and (iii) Parent shall, and shall cause the Surviving Corporation to, use all reasonable efforts to assist and cooperate in the vigorous defense of any such matter, provided that none of Parent, Merger Sub or the Surviving Corporation shall be liable for any settlement of any claim effected without its written consent, which consent, however, shall not be unreasonably withheld or delayed. Any D&O Indemnified Party wishing to claim indemnification under this Section 6.07, upon learning of any such D&O Claim, shall notify Parent, Merger Sub or the Surviving Corporation (but the failure so to notify an indemnifying party shall not relieve such indemnifying party from any liability which it may have under this Section 6.07 except to the extent such failure materially prejudices such indemnifying party), and shall deliver to Parent and the Surviving Corporation the undertaking contemplated by Section 13.1-699 of the VSCA. The D&O Indemnified Parties

as a group may retain only one law firm (in addition to local counsel in each applicable jurisdiction if reasonably required) to represent them with respect to each such matter unless there is, under applicable standards of professional conduct, a conflict on any significant issue between the positions of any two or more D&O Indemnified Parties. In the event any D&O Indemnified Party is required to bring any action to enforce rights or to collect moneys due under this Merger Agreement and is successful in such action, Parent shall reimburse such D&O Indemnified Party for all its expenses in bringing and pursuing such action. Each D&O Indemnified Party shall be entitled to the advancement of expenses to the full extent contemplated in this Section 6.07(a) in connection with any such action.

(b) Successors. In the event Parent or any of its successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and Assets to any Person, then and in either such case, proper provisions shall be made so that the continuing or surviving entity or transferee, as appropriate, shall assume the obligations set forth in this Section 6.07.

(c) Survival of Indemnification. To the fullest extent not prohibited by Law, from and after the Effective Time, all rights to indemnification as of the date hereof in favor of the D&O Indemnified Parties with respect to their activities as such prior to the Effective Time, as provided in their respective articles of incorporation and bylaws or comparable documents in effect on the date hereof, or otherwise in effect on the date hereof, shall survive the Merger and shall continue in full force and effect for a period of not less than six years from the Effective Time, provided that in the event any D&O Claim or Claims are asserted or made within such six-year period, all such rights to indemnification in respect of such claim or claims shall continue until the final disposition thereof.

SECTION 6.08 Tax Information

Parent will, or will cause Surviving Corporation to, provide to a Company Shareholder such tax-related information with respect to Company or the Merger as such Company Shareholder may reasonably request to enable such Company Shareholder to accurately prepare and make any tax filings required by Law.

(a) Except as provided in and subject to Section 9.02(b), each Company Shareholder shall indemnify, defend and hold Parent, the Surviving Corporation and their respective officers and directors, and each Person, if any, who controls or may control Parent or the Surviving Corporation within the meaning of the Securities Act (all such Persons hereinafter are referred to individually as an “Parent Indemnified Person” and collectively as “Parent Indemnified Persons,” but in no event shall any Company Shareholder be such a Parent Indemnified Person) harmless against all Losses (excluding any such Losses to the extent recoverable by any Parent Indemnified Persons under any applicable insurance policy) resulting from, imposed upon or incurred by any Parent Indemnified Person, directly or indirectly, as a result of any of the following:

(i) the failure of any representation or warranty of Company given or made by Company in this Merger Agreement or in the Company Disclosure Schedule or in any certificate delivered by or on behalf of Company pursuant hereto to be true and correct as of the date of this Merger Agreement and true and correct in all material respects as of the Closing Date as though made as of the Closing Date (except for (A) representations and warranties which address matters only as of a particular date, which representations and warranties shall be true and correct in all material respects as of such date and (B) changes permitted by or consistent with this Merger Agreement);

(ii) any failure by Company to perform or comply in all material respects with any covenant or obligation contained in this Merger Agreement or in any certificate delivered by or on behalf of Company pursuant hereto; and

(iii) in accordance with Section 5.11, the amount, if any, by which $8,200,000 exceeds the Net Tangible Assets of Company set forth on the Closing Net Tangible Assets Statement.

(b) Notwithstanding anything in this Merger Agreement to the contrary:

(i) the Company Shareholders, collectively, shall have no obligation to indemnify the Parent Indemnified Persons from and against any Losses pursuant to Section 9.02(a) until the aggregate of such Losses for all Parent Indemnified Persons exceeds $150,000 (at which point the Company Shareholders will be obligated to indemnify the Parent Indemnified Persons from and against all such aggregate Losses (including those Losses that constitute such $150,000)); provided, however, that such $150,000 threshold shall not apply to the amount, if any, due to Parent in accordance with Section 5.11 and Section 9.02(a)(iii), which amount shall instead be paid in full out of funds held in the Escrow Fund as promptly as practicable after delivery by Company to Parent of the Closing Balance Sheet and the Closing Net Tangible Assets Statement (subject to the resolution of any dispute with respect thereto), and such amount shall not be deemed a Loss for purposes of determining whether the threshold has been met; provided, further, however, that if a holder of valid shares of Company Common Stock presents one or more Certificates representing such Company Common Stock to Parent after Parent commences the distribution of the Merger Consideration pursuant to this Merger Agreement, and the shares of Company Common Stock represented by such Certificate(s) were not included in the calculation of the pro rata portion of the Merger Consideration allocable to each share of Company Common Stock, then Parent shall be reimbursed out of the Escrow Funds for the amount Parent is required to pay to such holder with respect to such Certificate(s), without regard to the $150,000 threshold, as promptly as practicable after Parent pays such amount to such holder (subject to the resolution of any dispute with respect thereto), and such amount shall not be deemed a Loss for purposes of determining whether the threshold has been met; and

(ii) the Company Shareholders shall not be required to make any payment with respect to any claim for indemnification pursuant to Section 9.02(a), including any payment pursuant to Section 5.11, in excess of an aggregate of Five Million Dollars ($5,000,000) (after which point each such Company Shareholder shall have no obligation to indemnify the Parent Indemnified Persons from and against any further Losses or pay Parent any further amounts pursuant to this Merger Agreement (including, without limitation, Section 5.11)); provided, however, that this limitation shall not apply to the obligation of a Company Shareholder to indemnify Parent Indemnified Persons from and against any Losses arising out of misrepresentations, breaches or defaults that result from or are attributable to fraud or willful misconduct of such Company Shareholder.

SECTION 9.03 Offset Against Escrow Fund

(a) If a Parent Indemnified Person shall suffer any Losses for which such Parent Indemnified Person shall be entitled to recover Losses under Section 9.02, such Parent Indemnified Person shall seek reimbursement of such Losses out of the Escrow Fund pursuant to the procedures set forth in and the provisions of the Escrow Agreement, which shall be the Parent Indemnified Persons’ sole remedy for such Losses; provided, however, that this limitation shall not apply with respect to an obligation of a Company Shareholder to indemnify the Parent Indemnified Persons for Losses arising out of misrepresentations, breaches or defaults that result from or are attributable to fraud or willful misconduct of such Company Shareholder.

(b) Subject to subsections (c) and (d) of this Section 9.04, if the Indemnifying Party assumes responsibility for Losses arising out of such Third Party Claim, then the Indemnifying
