AGREEMENT

The parties to this Agreement, intending to be legally bound, agree as follows:

SECTION 1. THE MERGER

1.1 MERGER OF MERGER SUB INTO THE COMPANY.

Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time (as defined in Section 1.3), Merger Sub shall be merged with and into the Company, and the separate corporate existence of Merger Sub shall cease. The Company will continue as the surviving corporation in the Merger (the “Surviving Corporation”) and will be a wholly-owned subsidiary of Parent.

1.2 EFFECT OF THE MERGER.

The Merger shall have the effects set forth in this Agreement and the applicable provisions of the DGCL and the GBCC.

1.3 CLOSING; EFFECTIVE TIME.

The consummation of the Merger (the “Closing”) shall take place at the offices of Heller Ehrman White & McAuliffe LLP, 275 Middlefield Road, Menlo Park, California at 10:00 a.m. on a date to be mutually agreed upon by Parent and the Company (the “Closing Date”), which date shall be no later than the third (3rd) business day after the conditions set forth in Section 6 shall have been satisfied or waived (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of such conditions), or

such other time as Parent and the Company shall mutually agree. Subject to the provisions of this Agreement, the certificate of merger in the form attached hereto as Exhibit E (the “Delaware Certificate of Merger”) and the certificate of merger in the form attached hereto as Exhibit F (the “Georgia Certificate of Merger”), together with such other documents as may be required by the relevant provision of the DGCL and the GBCC, shall be duly executed on behalf of the Company and simultaneously with the Closing delivered to the Secretary of State of the State of Delaware and the Secretary of State of the State of Georgia, respectively, for filing. The Merger shall become effective as of the date and time set forth in the Delaware Certificate of Merger and the Georgia Certificate of Merger (the “Effective Time”).

1.4 ARTICLES OF INCORPORATION AND BYLAWS.

(a) The articles of incorporation of the Surviving Corporation shall be amended and restated in the Merger in the form attached hereto as Exhibit G as set forth in the Georgia Certificate of Merger and the Delaware Certificate of Merger.

(b) The bylaws of the Surviving Corporation shall be amended and restated as of the Effective Time in the form attached hereto as Exhibit H.

(c) The directors and officers of the Surviving Corporation immediately after the Effective Time shall be the respective individuals who are the directors and officers of Merger Sub immediately prior to the Effective Time.

1.5 CONVERSION OF SHARES IN THE MERGER.

(a) At the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Merger Sub, the Company or any shareholder of the Company, subject to Section 1.5(b) and Section 1.5(c), each share of Company Common Stock then issued and outstanding, other than Excluded Shares, if any, shall be converted into the right to receive 0.4212 of a share (the “Exchange Ratio”) of Parent Common Stock (together with any cash in lieu of fractional shares of Parent Common Stock as set forth in Section1.5(c), the “Merger Consideration”).

(b) If, between the date of this Agreement and the Effective Time, the outstanding shares of Company Common Stock or Parent Common Stock are changed into a different number or class of shares by reason of any stock split, stock dividend, reverse stock split, reclassification, recapitalization or other similar transaction, including any such transaction with a record date between the date of this Agreement and the Effective Time, then the Exchange Ratio shall be appropriately adjusted to the extent the record date for any such event is between the date of this Agreement and the Effective Time, so as to provide the holders of Company Common Stock and Parent the same economic effect as contemplated prior to such stock split, stock dividend, reverse stock split, reclassification, recapitalization or other similar transaction.

(c) No fractional shares of Parent Common Stock shall be issued in connection with the Merger, and no certificates or scrip for any such fractional shares shall be issued. Any holder of Company Common Stock who would otherwise be entitled to receive a fraction of a share of Parent Common Stock pursuant to the Merger (after aggregating all fractional shares of Parent Common Stock issuable to such holder) shall, in lieu of such fraction of a share and upon surrender of such holder’s Company Stock Certificate(s) (as defined in Section 1.6), be paid in cash the dollar amount (rounded to the nearest whole cent), without interest, equal to the product obtained by multiplying (A) that fraction of a share of Parent Common Stock to which such shareholder would otherwise be entitled (after aggregating all fractional shares of Parent Common Stock otherwise issuable to such holder) by (B) the closing sales price of one (1) share of Parent Common Stock as reported on the Nasdaq (as reported in The Wall Street Journal or, if not reported therein, any other authoritative source) on the trading day immediately preceding the Effective Time.

(d) At the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Merger Sub, the Company or any stockholder of Merger Sub, each share of Common Stock, par value $.001 per share, of Merger Sub then issued and outstanding shall be converted into one validly issued, fully paid and nonassessable share of common stock, par value $.001 per share, of the Surviving Corporation and shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

1.6 CLOSING OF THE COMPANY’S TRANSFER BOOKS.

At the Effective Time: (a) all shares of Company Common Stock (“Shares”) outstanding immediately prior to the Effective Time shall automatically be canceled and shall cease to exist, each share of Company Common Stock shall represent only the right to receive the Merger Consideration and all holders of certificates representing Shares that were outstanding immediately prior to the Effective Time shall cease to have any rights as shareholders of the Company; and (b) the stock transfer books of the Company shall be closed with respect to all Shares outstanding immediately prior to the Effective Time. No further transfer of any such Shares shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any Shares (a “Company Stock Certificate”) is presented to the Exchange Agent (as defined in Section 1.7) or to the Surviving Corporation or Parent, such Company Stock Certificate shall be canceled and shall be exchanged as provided in this Section 1.

1.7 EXCHANGE OF CERTIFICATES.

(a) Prior to the Closing Date, Parent shall select a reputable bank or trust company reasonably acceptable to the Company to act as exchange agent in the Merger (the “Exchange Agent”). Within two (2) business days after the Effective Time, Parent shall deposit with the Exchange Agent, for the benefit of the holders of Shares, (i) certificates representing the shares of Parent Common Stock issuable pursuant to this Section 1, and (ii) cash sufficient to make payments in lieu of fractional shares in accordance with Section 1.5(c) (such cash and shares of Parent Common Stock, together with any dividends or distributions with respect thereto, being referred to as the “Exchange Fund”).

(b) As soon as reasonably practicable after the Effective Time, the Exchange Agent will mail to the record holders of Company Stock Certificates (i) a letter of transmittal in customary form and containing such provisions as Parent and the Company may reasonably specify (including a provision confirming that delivery of Company Stock Certificates shall be effected, and risk of loss and title to Company Stock Certificates shall pass, only upon delivery of such Company Stock Certificates to the Exchange Agent), and (ii) instructions for use in effecting the surrender of Company Stock Certificates in exchange for the Merger Consideration. Upon surrender of a Company Stock Certificate to the Exchange Agent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably required by the Exchange Agent or Parent, (A) the holder of such Company Stock Certificate shall be entitled to receive in exchange therefor the Merger Consideration, and (B) the Company Stock Certificate so surrendered shall be immediately canceled. Until surrendered as contemplated by this Section 1.7, each Company Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive the Merger Consideration and any distribution or dividend the record date for which is after the Effective Time. If any Company Stock Certificate shall have been lost, stolen or destroyed, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Company Stock Certificates the Merger Consideration; provided, however, that Parent may, in its discretion and as a condition precedent to the issuance of any certificate representing Parent Common Stock, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an appropriate affidavit and to deliver a bond (in such reasonable sum as Parent may reasonably direct) as indemnity against any claim that may be made against the Exchange Agent, Parent or the Surviving Corporation with respect to such Company Stock Certificate.

(c) No dividends or other distributions declared or made with respect to Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Company Stock Certificate with

respect to the shares of Parent Common Stock that such holder has the right to receive pursuant to the Merger until such holder surrenders such Company Stock Certificate in accordance with this Section 1.7.

(d) Any portion of the Exchange Fund that remains undistributed to holders of Company Stock Certificates as of the date one (1) year after the Effective Time shall be delivered to Parent upon demand, and any holders of Company Stock Certificates who have not theretofore surrendered their Company Stock Certificates to the Exchange Agent in accordance with this Section 1.7 shall thereafter look only to Parent for satisfaction of their claims for the Merger Consideration to which such holder is entitled pursuant hereto.

(e) Each of the Exchange Agent, Parent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Company Common Stock such amounts as may be required to be deducted or withheld therefrom under the Code or any provision of state, local or foreign tax law or under any other applicable Legal Requirement. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

(f) Neither Parent nor the Surviving Corporation shall be liable to any holder or former holder of Company Common Stock or to any other Person with respect to any shares of Parent Common Stock (or dividends or distributions with respect thereto), or for any cash amounts, properly delivered to any public official in compliance with any applicable abandoned property law, escheat law or similar Legal Requirement.

1.8 FURTHER ACTION.

If, at any time after the Effective Time, any further action is determined by Parent to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of Merger Sub and the Company, the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Merger Sub, in the name of the Company and otherwise) to take such action. Parent, Merger Sub and Surviving Corporation also shall take such further actions as may be necessary or desirable to ensure that the Exchange Agent sends out the letters of transmittal to the shareholders of the Company and issues certificates representing Parent Common Stock to such shareholders in accordance with Section 1.7.

1.9 TAX CONSEQUENCES.

For federal income tax purposes, the Merger is intended to constitute a reorganization within the meaning of Section 368 of the Code. The parties to this Agreement hereby adopt this Agreement as a “plan of reorganization” within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Treasury Regulations.

3.13 ENVIRONMENTAL MATTERS.

Each of the RITA Corporations is in compliance with, and has conducted its activities in compliance with, all applicable Environmental Laws, which compliance includes the possession by each of the RITA Corporations of all material permits and other Governmental Authorizations required under applicable Environmental Laws, and compliance with the terms and conditions thereof, except where the failure to so comply would not result in a material liability or clean up obligation on the RITA Corporations. The consummation of the transactions contemplated by this Agreement will not affect the validity of such material permits and Governmental Authorizations held by Parent or any of the RITA Corporations, and will not require any filing, notice, or remediation under any Environmental law. To the knowledge of Parent, there are no past or present events, conditions, activities, or practices which would reasonably be expected to prevent Parent’s or any of the RITA Corporations’ compliance in any material respect with any Environmental Law, or which would reasonably be expected to give rise to any material liability of Parent or any of the RITA Corporations under any Environmental Law. Within the past seven (7) years, none of the RITA Corporations has received any written notice, or to its knowledge, other communication (in writing or otherwise) that alleges that any of the RITA Corporations is not in material compliance with any Environmental Law, and Parent has no knowledge of any circumstances that would reasonably be expected to result in such claims or communications. To Parent’s

knowledge, no current or prior owner of any property owned, leased or controlled by any of the RITA Corporations has received any written notice or other communication (in writing or otherwise) that alleges that such current or prior owner or any of the RITA Corporations is not in compliance with any Environmental Law in such a manner as would be reasonably likely to would not result in a material liability or clean up obligation on any RITA Corporation. Neither Parent nor any of the RITA Corporations has assumed by contract, agreement or otherwise any liabilities or obligations arising under any Environmental Law, or is currently performing any required investigation, response or other corrective action under any Environmental Law. There are no underground storage tanks or related piping on any property owned, leased, controlled by or used by any of the RITA Corporations, and any former such tanks and piping have been removed or closed in accordance with applicable Environmental Laws. To Parent’s knowledge, all property that is owned by, leased to, controlled by or used by any of the RITA Corporations is free of any friable asbestos or asbestos-containing material.

3.14 LEGAL PROCEEDINGS; ORDERS.

Except as set forth in the Parent SEC Documents, there is no pending Legal Proceeding and, to Parent’s knowledge, within the past twenty-four (24) months no Person has threatened to commence any Legal Proceeding, that involves any of the RITA Corporations or any of the assets owned or used by any of the RITA Corporations, in each case which would be reasonably likely to be material to the RITA Corporations; and there is no Order to which any of the RITA Corporations, or any of the material assets owned or used by any of the RITA Corporations, is subject.

3.15 VOTE REQUIRED.

(a) The affirmative vote of a majority of the votes cast on the proposal to approve the issuance of Parent Common Stock pursuant to the Merger (provided that the total votes cast on the proposal represent over 50% in interest of all securities entitled to vote on the proposal) is the only vote of the holders of any class or series of Parent’s capital stock necessary to approve the issuance of Parent Common Stock pursuant to the Merger.

(b) The affirmative vote of Parent is the only vote of the holders of any class or series of Merger Sub’s capital stock necessary to approve this Agreement and otherwise approve and consummate the Merger as set forth herein.

3.16 NON-CONTRAVENTION; CONSENTS.

(a) contravene, conflict with or result in a violation of any of the provisions of the Parent Organization Documents or any resolution adopted by the stockholders, the Board of Directors or any committee of the Board of Directors of any of the RITA Corporations;

(c) contravene, conflict with or result in a violation of any of the terms or requirements of, or give any Governmental Body the right to revoke, withdraw, suspend, cancel, terminate or modify, any material Governmental Authorization that is held by any of the RITA Corporations or that is otherwise material to the business of any of the RITA Corporations or to any of the assets owned or used by any of the RITA Corporations; or

(d) contravene, conflict with or result in a violation or breach of, or result in a default under, any provision of any Parent Material Contract (except for any such violation or breach which by its terms can be cured and is so cured within the applicable cure period or where the non-breaching party has no right to accelerate or terminate as a result of such violation or breach), or give any Person the right to (i) declare a default or exercise any remedy under any Parent Material Contract, (ii) accelerate the maturity or performance of any Parent Material Contract, or (iii) cancel, terminate or modify any term of any Parent Material Contract.

Except as may be required by the Exchange Act, the DGCL and the rules and regulations of the Nasdaq (as such rules and regulations relate to the Registration Statement and the Proxy Statement) and such filings as may be required pursuant to the HSR and except for any Consent required under any Parent Material Contract, none of the RITA Corporations was, is or will be required to make any filing with or give any notice to, or obtain any Consent from, any Person in connection with (x) the execution, delivery or performance of this Agreement, or (y) the consummation of the Merger or any of the other transactions contemplated by this Agreement, except in the case of subsections (x) and (y), where the failure to make such filing, give such notice or obtain any such consent would not have a Material Adverse Effect on the RITA Corporations.

3.17 OPINION OF FINANCIAL ADVISOR.

The Parent’s Board of Directors has received the opinion of Wells Fargo Securities, LLC (“Wells Fargo”), financial advisor to Parent, that as of the date of this Agreement and subject to the assumptions, qualifications and limitations set forth therein, the Exchange Ratio is fair to Parent from a financial point of view. Parent will furnish an accurate and complete copy of said opinion to the Company.

3.18 FINANCIAL ADVISOR.

Except with respect to Wells Fargo, no broker, finder or investment banker is entitled to any brokerage, finder’s or other fee or commission in connection with the Merger or any of the other transactions contemplated by this Agreement based upon arrangements made by or on behalf of any of the RITA Corporations. Parent has furnished to the Company an accurate and complete copy of its agreement with Wells Fargo.

3.19 TAKEOVER STATUTES.

To Parent’s knowledge, no Takeover Laws (other than Section 203 of the DGCL) are applicable to the Merger, this Agreement, the Parent Voting Agreements or any of the transactions contemplated hereby and thereby. The action of the Board of Directors of Parent in approving this Agreement and the Parent Voting Agreements (and the transactions provided for herein and therein) is sufficient to render inapplicable to this Agreement and the Parent Voting Agreements (and the transactions provided for herein and therein) the restrictions on “business combinations” (as defined in Section 203 of the DGCL) as set forth in Section 203 of the DGCL. The provisions of Section 262 of the DGCL providing for appraisal rights do not apply to the Merger.

3.20 INFORMATION TO BE SUPPLIED.

None of the information supplied or to be supplied by or on behalf of Parent for inclusion or incorporation by reference in the Registration Statement will, at the time the Registration Statement is filed with the SEC or becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading. None of the information supplied or to be supplied by or on behalf of Parent for inclusion or incorporation by reference in the Parent Proxy Statement or the Company Proxy Statement will, at the time the Parent Proxy Statement or the Company Proxy Statement is mailed to the stockholders of Parent or the shareholders of the Company, as the case may be, or at the time of the Parent Stockholders’ Meeting or the Company’s Shareholders’ Meeting, contain any untrue statement of a material fact

or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading. The Parent Proxy Statement will comply as to form in all material respects with the applicable provisions of the Exchange Act and the rules and regulations promulgated by the SEC thereunder. Notwithstanding the foregoing, Parent makes no representation or warranty with respect to any information supplied by or to be supplied by the Company that is included or incorporated by reference in the foregoing documents.

3.21 FOREIGN CORRUPT PRACTICES ACT.

Neither Parent, any other RITA Corporation, any of the RITA Corporation’s officers, directors, nor, to Parent’s knowledge, any employees or agents (or stockholders), distributors, representatives or other persons acting on the express, implied or apparent authority of any RITA Corporation, have paid, given or received or have offered or promised to pay, give or receive, any bribe or other unlawful payment of money or other thing of value, any unlawful discount, or any other unlawful inducement, to or from any person or Governmental Body in the United States or elsewhere in connection with or in furtherance of the business of any of the RITA Corporations (including any unlawful offer, payment or promise to pay money or other thing of value (a) to any foreign official, political party (or official thereof) or candidate for political office for the purposes of influencing any act, decision or omission in order to assist any RITA Corporation in obtaining business for or with, or directing business to, any person, or (b) to any person, while knowing that all or a portion of such money or other thing of value will be offered, given or promised unlawfully to any such official or party for such purposes). Neither the business of Parent nor of any other RITA Corporation is in any manner dependent upon the making or receipt of such unlawful payments, discounts or other inducements. Neither Parent nor any other RITA Corporation has otherwise taken any action that could cause Parent or any other RITA Corporation to be in violation of the Foreign Corrupt Practices Act of 1977, as amended, the regulations thereunder, or any applicable Legal Requirements of similar effect.

3.22 REAL PROPERTY.

Parent has good and marketable title to, or a valid leasehold interest in, all of its real properties, in each case free and clear of all Encumbrances.

Schedule 3.22 of the Parent Disclosure Letter sets forth a true and correct list of all real property currently leased by each of the RITA Corporations identifying, with respect to each lease of such real property, the date of, the parties to, and any amendments, modifications, extensions or other supplements to such lease. No RITA Corporation has sent or received any written notice of any default under any of the leases of real property to which it is party. No RITA Corporation is in breach of, or in default under, any covenant, agreement, term or condition of or contained in any lease of real property to which it is a party and there has not occurred any event that with the lapse of time or the giving of notice or both could constitute such a default or breach.

3.23 INSURANCE POLICIES.

Parent has delivered to the Company prior to the date hereof a complete and accurate list of all insurance policies in force naming Parent, any of the other RITA Corporations or any director, officer or employee thereof as an insured or beneficiary or as a loss payable payee or for which Parent or any other RITA Corporation has paid or is obligated to pay all or part of the premiums. Neither Parent nor any other RITA Corporation has received notice of any pending or threatened cancellation or premium increase (retroactive or otherwise) with respect thereto, and each of the RITA Corporations is in compliance in all material respects with all conditions contained therein. There are no material pending claims against such insurance policies by Parent or any other RITA Corporation as to which insurers are defending under reservation of rights or have denied liability, and there exists no material claim under such insurance policies that has not been properly filed by Parent or any other RITA Corporation. Except for the self-insurance retentions or deductibles set forth in the policies contained in the aforementioned list, the policies are adequate in scope and amount to cover all prudent and reasonably foreseeable risks which may arise in the conduct of the business of the RITA Corporations that would reasonably be expected to have a Material Adverse Effect on the RITA Corporations.

(a) Effective as of the Effective Time, the Company Stock Option Plan and each Company Option that is outstanding immediately prior to the Effective Time, whether or not then exercisable or vested, shall be assumed by Parent. As of the Effective Time, each Company Option shall cease to represent a right to acquire shares of Company Common Stock and shall be converted automatically into an option to purchase shares of Parent Common Stock in an amount, at an exercise price and subject to such terms and conditions determined as provided below.

Each Company Warrant shall, to the full extent permitted by applicable law, be assumed by Parent in such a manner that it shall be exercisable upon the same terms and conditions as under the Company Warrant pursuant to which it was issued; provided that (A) each Company Warrant so assumed shall be exercisable for, and represent the right to acquire, that number of shares of Parent Common Stock (rounded down to the nearest whole share) equal to (i) the number of shares of Company Common Stock subject to such Company Warrant immediately prior to the Effective Time multiplied by (ii) the Exchange Ratio; (B) the exercise price per share of Parent Common Stock subject to each assumed Company Warrant shall be an amount equal to (i) the exercise price per share of Company Common Stock subject to such Company Warrant in effect immediately prior to the Effective Time divided by (ii) the Exchange Ratio (rounded up to the nearest whole cent). Prior to the Effective Time, the Company shall make all adjustments provided for in the Company Warrants with respect to the Company Warrants to facilitate the implementation of the provisions of this Section 5.4(d) and take such other action as may be necessary to effect this Section 5.4(d).

5.5 EMPLOYEE BENEFITS

(a) Welfare Plans. The Surviving Corporation will continue following the Effective Time to maintain each Company Welfare Plan for the benefit of the employees of the Acquired Corporations for a transition period to provide benefits that are comparable in the aggregate to the benefits provided under the Company Welfare Plans immediately prior to the Effective Time, and the transition period may be different for each such plan and will be set by Parent and/or the Surviving Corporation based on the time deemed necessary to effect a reasonable transition for such employees from participating in each Company Welfare Plan to participating in a comparable Parent and/or Surviving Corporation benefit arrangement maintained for similarly situated Parent employees, provided (i) no transition period for any Company Welfare Plan shall end before March 1, 2005 following the Effective Time, (ii) Parent and/or the Surviving Corporation shall adopt transition rules to prevent any loss of credit for participant contributions, payments, co-payments and the like if a transition period for a Company Welfare Plan ends before the end of the plan year for such plan and (iii) the Surviving Corporation will, subject to the obligations set forth in this Section 5.5(a), continue to maintain such each Company Welfare Plan subject to the same rights the Company had immediately before the Effective Time to administer, amend and terminate such plan.

(b) 401(k) Plan. Before the Effective Time, the Company will take all actions required to terminate the Company 401(k) Plan immediately before the Effective Time. Parent shall use its commercially reasonable efforts to cause the Parent 401(k) Plan to be amended to permit the employees who were eligible to participate in the Company 401(k) Plan immediately before the Effective Time to be eligible to participate in the Parent 401(k) Plan as of immediately following the Effective Time so that there will be no interruption in the rights of such employees to make pre-tax contributions under a Code Section 401(k) plan.

(c) Stock-Based Plans. Following the Effective Time, employees of the Acquired Corporations will be eligible to receive stock options and other stock-based awards under the stock-based plans maintained by the Parent and/or the Surviving Corporation on the same basis as similarly situated Parent employees.

(d) Employment Policies and Practices. The Surviving Corporation will continue following the Effective Time to maintain the generally applicable employment related policies and practices of the Acquired Corporations, including those related to vacation time, sick leave, personal time off and the like for a transition period, which transition period may be different for each such policy or practice and which period shall be set by Parent and/or Surviving Corporation based on the time deemed necessary to effect a reasonable transition for

such employees from being subject to any such policy or practice to being subject to a comparable Parent and/or Surviving Corporation policy or practice, if any, for similarly situated employees of Parent.

(e) Service and Vesting Credit. Parent and/or Surviving Corporation will treat an individual’s employment as an employee by the Acquired Corporations the same as employment as an employee by Parent and/or Surviving Corporation for purposes of satisfying any service requirement to participate in any Parent and/or Surviving Corporation benefit arrangement and to determine the extent to which a benefit earned under such a plan is non-forfeitable if such individual is employed as an employee by the Acquired Corporations at the Effective Time.

5.6 INDEMNIFICATION OF OFFICERS AND DIRECTORS.

(a) From and after the Effective Time, Parent and the Surviving Corporation, jointly and severally, shall honor all rights to indemnification existing as of the date of this Agreement in favor of (i) current and former directors, officers and employees of the Company (the “Indemnified Persons”) and (ii) those Persons who have indemnification agreements with the Company as of the date of this Agreement, for acts and omissions occurring prior to or at the Effective Time, as provided in the Company Organizational Documents and under each indemnification agreement with the Indemnified Persons to which the Company is a party (as each is in effect as of the date of this Agreement), for a period of six (6) years from the Effective Time. The articles of incorporation and Bylaws of the Surviving Corporation will contain provisions with respect to exculpation and indemnification that are at least as favorable to those contained in the Company Organizational Documents, which provisions will not be amended, repealed or otherwise modified for a period of six (6) years from the Effective Time in any manner that would adversely affect the rights thereunder of Indemnified Persons, unless such modification is required by applicable Legal Requirements.

(b) For a period of six (6) years from the Effective Time, Parent and the Surviving Corporation shall, jointly and severally, provide for officers’ and directors’ liability insurance for the benefit of each Person (other than the Company) named as an insured party in any officers’ and directors’ liability insurance policy held by the Company as of the date of this Agreement (the “Insured Parties”), on terms with respect to such coverage no less favorable than those of such policy in effect on the date of this Agreement, covering only those acts or omissions occurring prior to or at the Effective Time; provided that neither Parent nor the Surviving Corporation shall be required to maintain such policies to the extent the cost of maintaining the same shall increase by more than 175% from the cost most recently incurred by the Company for maintaining the same (the “Current D&O Insurance Cost”), in which case Parent or the Surviving Corporation shall maintain as much comparable insurance as can be obtained for such amount. Prior to the Effective Time, the Company shall take all reasonable actions requested by Parent to maintain such directors and officers liability insurance. The Company represents to Parent and Merger Sub that the Current D&O Insurance Cost is $342,133.

(c) The terms of this Section 5.6 are intended to be for the benefit of and shall be enforceable by the Indemnified Parties and the Insured Parties and their heirs and personal representatives and shall be binding on Parent and the Surviving Corporation and their successors and assigns. In the event Parent or the Surviving Corporation (or any of their successors and assigns) (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each case, proper provision shall be made so that the successor or assign of Parent or the Surviving Corporation, as the case may be, honors the obligation set forth with respect to Parent or the Surviving Corporation, as the case may be, in this Section 5.6.
