SECTION 1.03 Effective Time. Prior to the Closing, the Company shall prepare, and on the Closing Date or as soon as practicable thereafter, the Company shall file with the Secretary of State of the State of Delaware a certificate of merger (the "Certificate of Merger") executed in accordance with the relevant provisions of the DGCL, and Parent and the Company shall make all other filings or recordings required under the DGCL in connection with the Merger. The Merger shall become effective on such date as the Certificate of Merger is duly filed with the Secretary of State of the State of Delaware, or on such later date as the parties hereto may agree and specify in the Certificate of Merger (the date and time the Merger becomes effective being the "Effective Time"). SECTION 1.04 Effects of the Merger. The Merger shall have the effects set forth in the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the property, rights, privileges, immunities, powers, franchises and authority of the Company and Sub will be vested in the Surviving Corporation, and all debts, liabilities and duties of the Company and Sub will become the debts, liabilities and duties of the Surviving Corporation. SECTION 1.05 Certificate of Incorporation and Bylaws.

(b) The Bylaws of Sub, as in effect immediately prior to the Effective Time, shall be the Bylaws of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law. SECTION 1.06. Directors and Officers of the Surviving Corporation.

The parties hereto adopt this Agreement as a "plan of reorganization" within the meaning of Sections 354 and 361 of the Code and Sections 1.368-2(g) and 1.368-3(a) of the Treasury Regulations and for all relevant Tax purposes. ARTICLE II EFFECT OF THE MERGER ON THE SHARES OF THE CONSTITUENT CORPORATIONS; SURRENDER OF CERTIFICATES AND PAYMENT SECTION 2.01. Certificate Amendments. Prior to the Closing, (i) Parent shall amend its Certificate of Incorporation to (A) effect a 1-for-1.67 reverse split of the shares of Parent Common Stock outstanding as of May 24, 2007 and (B) increase the number of authorized shares of Parent Common Stock from 40,000,000 to 100,000,000 (the "Parent Certificate Amendments") and (ii) the Company shall, by means of the Company Certificate Amendments described in Section 3.01(c), (A) convert its outstanding convertible preferred stock into Company Common Shares and (B) increase the number of authorized Company Common Shares. SECTION 2.02. Merger Consideration. Subject to the terms and conditions of this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of Parent, Sub or any holder of shares of the Company: (a) Each common share, par value $.01 per share, of the Company ("Company Common Share") issued and outstanding immediately prior to the Effective Time (other than Company Common Shares held directly or indirectly by the Company ("Treasury Shares"), Dissenting Shares and Company Common Shares owned by Parent, Sub or any other wholly owned subsidiary of Parent) will be extinguished, cancelled and automatically converted into the right to receive 0.0358493 (the "Exchange Ratio") fully paid and nonassessable shares of Parent Common Stock ("Merger Consideration"). (b) Each Company Common Share that, immediately prior to the Effective Time, is a Treasury Share or is owned directly by Parent, Sub or any other wholly owned subsidiary of Parent will be canceled and retired and will cease to exist, and no exchange or payment will be made therefor. (c) At the Effective Time, each common share, par value $.01 per share, of Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one fully paid and nonassessable common share, par value $.01 per share, of the Surviving Corporation. SECTION 2.03. Rights as Shareholders; Share Transfers. At the Effective Time, holders of Company Common Shares will cease to be, and will have no rights as, shareholders of the Company, other than the right to receive (a) any dividend or other distribution with respect to such Company Common Shares with a record date occurring prior to the Effective Time and (b) the Merger Consideration provided under Section 2.02, provided that in the case of holders of Dissenting Shares, such shareholders shall have the rights described in Section 2.07 in lieu of any rights to the Merger Consideration. After the Effective Time, there will be no transfers of Company Common Shares on the share transfer books of the Surviving Corporation. If, after the Effective Time, any certificates formerly representing Company Common Shares are presented to Parent, the Surviving Corporation or the Exchange Agent for any reason, they shall be canceled and exchanged as provided in this Article II. SECTION 2.04. Fractional Shares. Notwithstanding any other provision in this Agreement, no fractional shares of Parent Common Stock, and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Merger. Any fractional share interests to which a holder of Company Common Shares would otherwise be entitled under Section 2.02 shall be rounded to the nearest whole number. No cash shall be issued in lieu of any fractional shares. SECTION 2.05. Exchange of Certificates. (a) Exchange Agent. Prior to the Effective Time, Parent and Company will designate a national bank, trust company or transfer agent to act as agent of Parent for purposes of, among other things, mailing and receiving transmittal letters and distributing the Merger Consideration to the Company stockholders (the "Exchange Agent"). As of the Effective Time, Parent and the Exchange Agent shall enter into an agreement which will provide that Parent shall deposit with the Exchange Agent as of the Effective Time, for the benefit of the holders of Company Common Shares, for exchange in accordance with this Article II, through the Exchange Agent, certificates representing the shares of Parent Common Stock (such shares of Parent Common Stock, together with any dividends or distributions with respect thereto with a record date after the Effective Time, being hereinafter referred to as the "Exchange Fund") issuable pursuant to Section 2.02 in exchange for outstanding Company Common Shares. (b) Exchange Procedures. (i) As promptly as practicable after the Effective Time, the Exchange Agent will mail to each holder of record of a certificate formerly representing Company Common Shares (a "Company Certificate") whose Company Common Shares were converted into the right to receive the Merger Consideration (A) a letter of transmittal (which will specify that delivery will be effected, and risk of loss and title to the Company Certificates will pass, only upon proper delivery of the Company Certificates to the Exchange Agent and will be in such form and have such other provisions as Parent and the Company may specify consistent with this Agreement) and (B) instructions for use in effecting the surrender of the Company Certificates in exchange for the Merger Consideration. (ii) After the Effective Time, and upon surrender in accordance with Section 2.05(b)(i) of a Company Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Company Certificate will be entitled to receive in exchange therefor the Merger Consideration that such holder has the right to receive pursuant to the provisions of this Article II, and certain dividends or other distributions, if any, in accordance with this Article II, and the Company Certificate so surrendered will forthwith be canceled. In the event of a transfer of ownership of Company Common Shares that are not registered in the transfer records of the Company, payment may be issued to a person other than the person in whose name the Company Certificate so surrendered is registered (the "Transferee") if such Company Certificate is properly endorsed or otherwise in proper form for transfer and the Transferee pays any transfer or other Taxes required by reason of such payment to a person other than the registered holder of such Company Certificate or establishes to the satisfaction of the Exchange Agent that such Tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.05, each Company Certificate will be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration that the holder thereof has the right to receive in respect of such Company Certificate pursuant to the provisions of this Article II, and certain dividends or other distributions, if any, in accordance with Section 2.05(c). (c) Dividends; Other Distributions. No dividends or other distributions with respect to Parent Common Stock with a record date after the Effective Time will be paid to the holder of any unsurrendered Company Certificate with respect to the shares of Parent Common Stock represented thereby, and all such dividends and other distributions will be paid by Parent to the Exchange Agent and will be included in the Exchange Fund, in each case until the surrender of such Company Certificate in accordance with this Article II. Subject to the effect of applicable escheat or similar Laws, following surrender of any such Company Certificate in accordance herewith, there will be paid to the holder of the certificate representing whole shares of Parent Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Parent Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such whole shares of Parent Common Stock. (d) No Further Ownership Rights in Company Common Shares. All shares of Parent Common Stock issued in accordance with the terms of this Article II (including any cash paid pursuant to Section 2.05(c)) will be deemed to have been issued or paid, as the case may be, in full satisfaction of all rights pertaining to the Company Common Shares theretofore represented by such Company Certificates, and there will be no further registration of transfers on the stock transfer books of the Surviving Corporation of Company Common Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Company Certificates are presented to Parent, the Surviving Corporation or the Exchange Agent for any reason, they will be canceled and exchanged as provided in this Article II. (e) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of the Company Certificates for six months after the Effective Time will be delivered to Parent, upon demand, and any holders of Company Certificates who have not theretofore complied with this Article II may thereafter look only to Parent for payment of their claim for Merger Consideration and any dividends or distributions, if any, with respect to Parent Common Stock. (f) No Liability. None of Parent, the Surviving Corporation or the Exchange Agent will be liable to any person in respect of any shares of Parent Common Stock, any dividends or distributions with respect thereto, in each case, delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. (g) Lost Certificates. If any Company Certificate has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Company Certificate to be lost, stolen or destroyed and, if required by Parent or the Surviving Corporation, as the case may be, the posting by such person of a bond in such reasonable amount as Parent or the Surviving Corporation, as the case may be, may direct as indemnity against any claim that may be made against it with respect to such Company Certificate, the Exchange Agent shall issue, in exchange for such lost, stolen or destroyed Company Certificate, the Merger Consideration and, if applicable, any unpaid dividends and distributions on shares of Parent Common Stock deliverable in respect thereof, in each case, due to such person pursuant to this Agreement. SECTION 2.06. Anti-Dilution Adjustments. Except with respect to the transactions contemplated by the Parent Certificate Amendments, should Parent change (or establish a record date for changing) the number of shares of Parent Common Stock issued and outstanding prior to the Effective Time by way of a split, dividend, combination, recapitalization, exchange of shares or similar transaction with respect to the outstanding Parent Common Stock having a record date preceding the Effective Time, the Exchange Ratio will be adjusted appropriately to provide to the holders of Company Common Shares the same economic effect as contemplated by this Agreement prior to such split, dividend, combination, recapitalization, exchange of shares or similar transaction. SECTION 2.07. Dissenter's Rights. Company Common Shares that have not been voted for adoption of this Agreement and with respect to which appraisal has been properly demanded in accordance with Section 262 of the DGCL ("Dissenting Shares") will not be converted into the right to receive the Merger Consideration at or after the Effective Time unless and until the holder of such shares withdraws such demand for such appraisal (in accordance with Section 262(k) of the DGCL) or becomes ineligible for such appraisal. If a holder of Dissenting Shares withdraws such demand for appraisal (in accordance with Section 262(k) of the DGCL) or becomes ineligible for such appraisal, then, as of the Effective Time or the occurrence of such event, whichever last occurs, each of such holder's Dissenting Shares will cease to be a Dissenting Share and will be converted into and represent the right to receive the Merger Consideration, without interest thereon. The Company shall give Parent prompt notice of any demands for appraisal, attempted withdrawals of such demands and any other instruments received by the Company relating to stockholders' rights of appraisal. Parent shall conduct all negotiations and proceedings with respect to demand for appraisal under the DGCL and the Company will be entitled to participate in such negotiations only as and to the extent requested by Parent. The Company shall not, except with the prior written consent of Parent, make any payment with respect to any demands for appraisal of Dissenting Shares, compromise or offer to settle or settle any such demands or approve any withdrawal of any such demands. SECTION 2.08. Restrictions on Transfer. The shares of Parent Common Stock that are being issued in connection with the Merger (the "New Parent Shares"), and any shares of Parent Common Stock issuable upon exercise of options issued pursuant to Section 5.03 (collectively, with the New Parent Shares, the "New Parent Securities") are being issued pursuant to an exemption from registration provided for in Section 4(2) of the Securities Act of 1933, as amended (the "Securities Act"). Each certificate representing any New Parent Securities shall be subject to stop transfer instructions and shall bear all legends required under all applicable securities Laws.

SECTION 4.02. No Solicitation by the Company. (a) Other than as set forth in Section 4.02 of the Company Disclosure Letter, from and after the date of this Agreement, the Company shall not, nor shall it permit any Company Subsidiary to, nor shall it authorize or knowingly permit any officer, director or employee of or any investment banker, attorney, accountant or other advisor or representative (collectively, the "Company Representatives") of, the Company or any Company Subsidiary to, (i) solicit, initiate or knowingly encourage the submission of any Company Takeover Proposal, (ii) enter into any agreement with respect to any Company Takeover Proposal or (iii) other than informing persons of the existence of this Section 4.02, provide any non-public information regarding the Company to any third party or engage in any negotiations or substantive discussions in connection with any Company Takeover Proposal; provided, however, that prior to receipt of the Company Shareholder Approval, the Company and the Company Representatives may, in response to a Company Takeover Proposal that was not solicited by the Company, provide any non-public information regarding the Company to any third party or engage in any negotiations or substantive discussions with such person regarding any Company Takeover Proposal, in each case only if the Company's Board of Directors determines in good faith, after consultation with counsel and its financial advisor, that such actions could result in a Company Superior Proposal. For purposes of this Agreement, "Company Takeover Proposal" means (i) any inquiry, proposal or offer for a merger, consolidation, business combination or other similar transaction involving the Company, (ii) any inquiry, proposal or offer to acquire in any manner, directly or indirectly, more than 25% of the outstanding Company Common Shares or (iii) any inquiry, proposal or offer to acquire in any manner, directly or indirectly, assets of the Company or the Company Subsidiaries representing more than 25% of the consolidated assets of the Company, in each case other than the transactions contemplated by this Agreement.

(b) At any time after the date hereof and prior to receipt of the Company Shareholder Approval, (x) in response to a Company Takeover Proposal which was not solicited by the Company, the Board of Directors of the Company may terminate this Agreement pursuant to Section 7.01(d) and cause the Company to enter into an agreement with respect to any Company Superior Proposal, and (y) the Board of Directors of the Company may withdraw or modify in a manner adverse to Parent its recommendation to the Company's shareholders that they give the Company Shareholder Approval, but only if and to the extent that the Company's Board of Directors determines in good faith, after consultation with counsel and its financial advisor, that failing to take any such action could result in a breach of the fiduciary duties of the Company's Board of Directors. The term "Company Superior Proposal" means a Company Takeover Proposal that the Company's Board of Directors determines in good faith, after consultation with counsel and its financial advisor and taking into account all legal, financial and regulatory and other aspects of the Company Takeover Proposal, the person making the Company Takeover Proposal and all relevant material terms of such Company Takeover Proposal and this Agreement (including any changes to this Agreement proposed by Parent in response to a Company Takeover Proposal), is more favorable to the shareholders of the Company than the Merger and the other transactions contemplated by this Agreement and for which financing, to the extent required, is then committed or may reasonably be expected to be committed. SECTION 4.03. No Solicitation by Parent. (a) From and after the date of this Agreement, Parent shall not, nor shall it authorize or knowingly permit any officer, director or employee of or any investment banker, attorney, accountant or other advisor or representative (collectively, the "Parent Representatives") of, Parent to, (i) solicit, initiate or knowingly encourage the submission of any Parent Takeover Proposal, (ii) enter into any agreement with respect to any Parent Takeover Proposal or (iii) other than informing persons of the existence of this Section 4.02, provide any non-public information regarding Parent to any third party or engage in any negotiations or substantive discussions in connection with any Parent Takeover Proposal.

Parent shall immediately cease and cause to be terminated any existing activities, discussions or negotiations by Parent or any Parent Representative, with any parties conducted heretofore with respect to any of the foregoing. (b) Parent promptly shall advise the Company orally and in writing of the receipt of any Parent Takeover Proposal and of the material terms of any such Parent Takeover Proposal and of any changes thereto. Parent promptly shall advise the Company orally and in writing of the commencement of any discussions with any third party or its representatives regarding a Parent Takeover Proposal by such third party. ARTICLE V ADDITIONAL AGREEMENTS SECTION 5.01. Access to Information; Confidentiality. Each party shall, upon reasonable notice, afford to the other party and to the officers, directors, employees, accountants, counsel, financial advisors and other representatives of such other party, reasonable access during normal business hours during the period prior to the Effective Time to all their respective books, records, properties and other assets. Each party shall be entitled to make extracts and copies of such books and records. Each party shall, with the prior consent of the other (which consent shall not be unreasonably withheld or delayed), be permitted to contact and communicate with the other party's customers, employees, distributors and suppliers. All reviews conducted pursuant to this Section 5.01 shall be conducted in such manner as shall not interfere unduly with the operations of the parties' respective businesses, and information disclosed in connection therewith shall be held in confidence. SECTION 5.02. Reasonable Best Efforts; Notification. (a) Upon the terms and subject to the conditions set forth in this Agreement, each of the parties shall use reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Merger and the other transactions contemplated by this Agreement, including (i) the obtaining of all necessary actions or nonactions, waivers, consents and approvals from Governmental Entities and the making of all necessary registrations and filings (including filings with Governmental Entities, if any) and the taking of all reasonable steps as may be necessary to obtain an approval or waiver from, or to avoid an action or proceeding by, any Governmental Entity, (ii) the obtaining of all necessary consents, approvals or waivers from third parties, (iii) the defending of any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated by this Agreement including seeking to have any stay or temporary restraining order entered by any court or other Governmental Entity vacated or reversed, and (iv) the execution and delivery of any additional instruments necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement. Each party will consult with counsel for the other parties as to, and will permit such counsel to participate in, any litigation referred to in clause (iii) above. In connection with and without limiting the foregoing, Parent, the Company and their respective Boards of Directors shall (x) take all action necessary so that no takeover statute or similar statute or regulation is or becomes applicable to the Merger, this Agreement or any other transaction contemplated by this Agreement and (y) if any takeover statute or similar statute or regulation becomes applicable to the Merger, this Agreement or any other transaction contemplated by this Agreement, take all action necessary so that the Merger and the other transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on the Merger and the other transactions contemplated by this Agreement. Notwithstanding any provision to the contrary in this Section 5.02, the Company and the Company Representatives shall not be prohibited under this Section 5.02 from taking any action permitted by Section 4.02. (b) Each of Parent and the Company will (x) promptly notify the other party of any written communication to that party from any Governmental Entity located in the United States and, to the extent practicable, outside of the United States, in each case, with respect to this Agreement and the Merger, and, subject to applicable Law, permit the other party to review in advance any proposed written communication to any such Governmental Entity and incorporate the other party's reasonable comments, (y) not agree to participate in any substantive meeting or discussion with any such Governmental Entity in respect of any filing, investigation or inquiry concerning this Agreement or the Merger unless it consults with the other party in advance and, to the extent permitted by such Governmental Entity, gives the other party the opportunity to attend or participate and (z) furnish the other party with copies of all correspondence, filings and written communications between them and their affiliates and their respective representatives on one hand, and any such Governmental Entity or its respective staff on the other hand, with respect to this Agreement and the Merger. If any administrative or judicial action or proceeding is instituted (or threatened to be instituted) challenging any transaction contemplated by this Agreement as violative of any applicable competition, merger control, antitrust or similar Law, or if any statute, rule, regulation, executive order, decree, injunction or administrative order is enacted, entered, promulgated or enforced by a Governmental Entity that would make the Merger or the other transactions contemplated by this Agreement illegal or would otherwise prohibit or materially impair or delay the consummation of the Merger or the other transactions contemplated by this Agreement, each of Parent and the Company shall cooperate in all respects with the other and use its reasonable best efforts to contest and resist any such action or proceeding and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the Merger or the other transactions contemplated by this Agreement and to have such statute, rule, regulation, executive order, decree, injunction or administrative order repealed, rescinded or made inapplicable so as to permit consummation of the transactions contemplated by this Agreement. (c) The Company shall give prompt notice to Parent, and Parent and Sub shall give prompt notice to the Company, of (i) any representation or warranty made by it or contained in this Agreement becoming untrue in any material respect, or (ii) the failure by it to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of the parties under this Agreement. SECTION 5.03. Stock Options. (a) Assumption of Company Stock Options. At the Effective Time, (i) each outstanding Company Stock Option set forth in Section 5.03 of the Company Disclosure Letter (the "Assumed Options"), whether vested or unvested immediately prior to the Effective Time, to purchase Company Common Shares, and (ii) the Company Share Plans and all agreements relating to the Assumed Options shall be assumed by Parent. Each Assumed Option shall continue to have, and be subject to, substantially the same terms and conditions as were applicable under the Company Share Plans and the documents governing the Company Stock Options immediately before the Effective Time, except that (x) each Assumed Option will be exercisable for that number of whole shares of Parent Common Stock equal to the product of the number of shares of Company Common Shares that were issuable upon exercise of such option immediately prior to the Effective Time multiplied by the Exchange Ratio (rounded to the nearest whole number of shares of Parent Common Stock) and (y) the per share exercise price for the shares of Parent Common Stock issuable upon exercise of such Assumed Option will be equal to the quotient determined by dividing the per share exercise price of the Company Stock Option by the Exchange Ratio (rounded up to the nearest whole cent). The date of grant of each Assumed Option will be the date on which the corresponding Company Stock Option was granted. Notwithstanding the foregoing, with respect to each Company Stock Option that is an incentive stock option (within the meaning of Section 422(b) of the Code), no adjustment will be made that would be a modification (within the meaning of Section 424(h) of the Code) to such option. (b) Stock Plans. The Company and Parent agree that the Company Share Plans and all relevant stock plans of Parent ("Parent Stock Plans") will be amended, to the extent necessary, to reflect the transactions contemplated by this Agreement, including conversion of Company Common Shares held or to be awarded or paid pursuant to such benefit plans, programs or arrangements into shares of Parent Common Stock on a basis consistent with the transactions contemplated by this Agreement. The Company and Parent agree to submit the amendments to the Parent Stock Plans or the Company Share Plans to their respective stockholders if such submission is determined to be necessary by counsel to the Company or Parent after consultation with one another; provided, however, that such approval will not be a condition to the consummation of the Merger. (c) Reservation of Shares. Parent will (i) reserve for issuance the number of shares of Parent Common Stock that will become subject to the benefit plans, programs and arrangements referred to in this Section 5.03 and (ii) issue or cause to be issued the appropriate number of shares of Parent Common Stock, pursuant to applicable plans, programs and arrangements, upon the exercise or maturation of rights existing thereunder at the Effective Time or thereafter granted or awarded. (d) Notices. As soon as practicable after the Effective Time, Parent will deliver to the holders of the Assumed Options appropriate notices setting forth such holders' rights pursuant to the Company Share Plans and the agreements evidencing the grants of such Company Stock Options and that such Company Stock Options and the related agreements will be assumed by Parent and will continue in effect on the same terms and conditions (subject to the adjustment required by this Section 5.03 after giving effect to the Merger). As soon as practicable after the Effective Time and no later than 15 days thereafter, Parent will file the Certificate of Compliance with the Bankruptcy Court and provide written confirmation of the completion of reverse merger to the holders of the Parent Common Stock. SECTION 5.04. Indemnification. (a) Parent shall, and shall cause the Surviving Corporation to, jointly and severally, honor all the Company's obligations to indemnify (including any obligations to advance funds for expenses) the current or former directors and officers of the Company for acts or omissions by such directors and officers occurring prior to the Effective Time to the extent that such obligations of the Company exist on the date of this Agreement, whether pursuant to the Company's Amended and Restated Certificate of Incorporation, Amended and Restated Bylaws, individual indemnity agreements or otherwise, and such obligations shall survive the Merger and shall continue in full force and effect in accordance with the terms of such Amended and Restated Certificate of Incorporation, Amended and Restated Bylaws and individual indemnity agreements from the Effective Time until the expiration of the applicable statute of limitations with respect to any claims against such directors or officers arising out of such acts or omissions. (b) For a period of six years commencing immediately after the Effective Time, Parent shall cause to be maintained in effect the current policies of directors' and officers' liability insurance maintained by the Company with respect to claims arising from or related to facts or events which occurred at or before the Effective Time. (c) From and after the Effective Time, to the fullest extent permitted by Law, Parent shall, and shall cause the Surviving Corporation to, indemnify and hold harmless the present and former officers and directors of the Company and the Company Subsidiaries (each an "Indemnified Party") against all losses, claims, damages, liabilities, fees and expenses (including attorneys' fees and disbursements), judgments, fines and amounts paid in settlement (in the case of settlements, with the approval of the indemnifying party (which approval shall not be unreasonably withheld)) (collectively, "Losses"), as incurred (payable monthly within 5 business days after the written request by the Indemnified Party, which request shall include reasonable evidence of the Losses set forth therein) to the extent arising from, relating to, or otherwise in respect of, any actual or threatened action, suit, proceeding or investigation, in respect of actions or omissions occurring at or prior to the Effective Time in connection with such Indemnified Party's duties as an officer or director of the Company or any Company Subsidiary, including in respect of this Agreement, the Merger and the other transactions contemplated by this Agreement; provided, however, that an Indemnified Party shall not be entitled to indemnification under this Section 5.04(c) for Losses arising out of actions or omissions by the Indemnified Party constituting criminal conduct. (d) The provisions of this Section 5.04 are (i) intended to be for the benefit of, and will be enforceable by, each Indemnified Party, his or her heirs and his or her representatives and (ii) in addition to, and not in substitution for, any other rights to indemnification or contribution that any such person may have by contract or otherwise. (e) If the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any person, then, and in each such case, to the extent necessary proper provisions will be made so that the successors or assigns of the Surviving Corporation, as the case may be, shall assume the obligations set forth in this Section 5.04. (f) In the event any action, suit, proceeding or investigation is asserted or made, any determination required to be made with respect to whether an Indemnified Party's conduct complies with the standards set forth under the DGCL, the applicable organizational documents of the Company or the Company Subsidiaries or any indemnification agreements or arrangements of the Company or the Company Subsidiaries, as the case may be, shall be made by independent legal counsel selected by Parent and reasonably acceptable to such Indemnified Party; provided, however, that nothing in this Section 5.04 shall impair any rights of any current or former director or officer of the Company or any Company Subsidiary, including pursuant to the respective certificates of incorporation of the Surviving Corporation or the Company, or their respective subsidiaries, under the DGCL or otherwise. (g) Each of Parent, the Surviving Corporation and the Indemnified Parties shall cooperate, and cause their respective affiliates to cooperate, in the defense of any action, suit, proceeding or investigation and shall provide access to properties and individuals as reasonably requested and furnish or cause to be furnished records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials or appeals, as may be reasonably requested in connection therewith. (h) The obligations of Parent and the Surviving Corporation under this Section 5.04 shall not be terminated or modified in such a manner as to adversely affect any Indemnified Party to whom this Section 5.04 applies without the consent of the affected Indemnified Party (it being expressly agreed that the Indemnified Parties to whom this Section 5.04 applies shall be third party beneficiaries of this Section 5.04). SECTION 5.05. Fees and Expenses. All fees and expenses, including any fees payable to any broker, investment banker, counsel or financial advisor, incurred in connection with the Merger, this Agreement and the transactions contemplated by this Agreement shall be paid by the party incurring such fees or expenses, whether or not the Merger is consummated.

Each of Parent, Sub and the Company shall use its reasonable best efforts to cause the Merger to qualify as a reorganization under the provisions of Section 368(a) of the Code, including forbearing from taking any action that would cause the Merger not to qualify as a reorganization under the provisions of Section 368(a) of the Code.
