AGREEMENT AND PLAN OF MERGER

This AGREEMENT AND PLAN OF MERGER is made and entered into as of September 30, 2005, by and among ▇▇▇▇ Innovations Incorporated, a Delaware corporation (“Parent”); ▇▇▇▇ Technologies Acquisition Corp., a Delaware corporation and wholly-owned subsidiary of Parent (“Sub”); ▇▇▇▇ Technologies, Inc., a Delaware corporation (the “Company”); and the Principal Stockholders identified on Annex A hereto. Capitalized terms used and not otherwise defined herein have the meanings given to them in Article 8.

RECITALS

A. The Boards of Directors of each of the Company, Parent and Sub have determined it to be advisable and in the best interests of each company and its respective stockholders that Parent acquire the Company through the statutory merger of the Company with and into Sub (the “Merger”) and, in furtherance thereof, have approved this Agreement and declared its advisability.

B. The Company, the Principal Stockholders, Parent and Sub desire to make certain representations, warranties, covenants and other agreements in connection with the Merger.

NOW, THEREFORE, in consideration of the covenants, promises, representations and warranties set forth herein, and for other good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged by the parties), intending to be legally bound hereby, the parties agree as follows:

ARTICLE 1

THE MERGER

1.1 The Merger. At the Effective Time, and upon the terms and subject to the conditions of this Agreement and the applicable provisions of Delaware Law, Sub shall be merged with and into the Company, the separate corporate existence of Sub shall cease, and the Company shall continue as the surviving corporation and as a wholly-owned subsidiary of Parent. The surviving corporation in the Merger is sometimes referred to herein as the “Surviving Corporation.”

1.2 Effective Time. The parties hereto shall consummate the Merger and the transactions contemplated hereby at a closing (the “Closing”) to be held immediately after the execution and delivery of this Agreement by the parties hereto at the offices of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇, Professional Corporation, ▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇, unless another time and/or place is mutually agreed upon in writing by Parent and the Company. The date upon which the Closing actually occurs is herein referred to as the “Closing Date.” On the Closing Date, the certificate of merger (the “Certificate of Merger”), substantially in the form of Exhibit A hereto, shall be duly prepared and executed by the Surviving Corporation and thereafter delivered to the Secretary of State of the State of Delaware for filing, as provided in Section 251 of Delaware Law, on the Closing Date. The parties shall make all other filings required under Delaware Law, and the Merger shall become effective at the time of the filing of the Certificate of Merger with the Secretary of State, or at such later time as may be agreed by Parent and the Company and stated in the Certificate of Merger (the date and time of such filing (or stated later time, if any) being referred to herein as the “Effective Time”).

1.3 Effect of the Merger on Constituent Corporations. At the Effective Time, the effects of the Merger shall be as provided in the applicable provisions of Delaware Law.

1.4 Certificate of Incorporation and Bylaws of Surviving Corporation.

(a) At the Effective Time, the Certificate of Incorporation of the Surviving Corporation shall be amended and restated in its entirety to read as set forth on Exhibit B hereto, which Exhibit B shall be filed with the Certificate of Merger.

(b) The Bylaws of Sub as in effect immediately prior to the Effective Time shall be the Bylaws of the Surviving Corporation at the Effective Time, until thereafter amended in accordance with Delaware Law and as provided in the Certificate of Incorporation of the Surviving Corporation and such Bylaws.

1.5 Directors and Officers of Surviving Corporation. The directors of Sub immediately prior to the Effective Time shall be the directors of the Surviving Corporation, each to hold office in accordance with the certificate of incorporation and bylaws of the Surviving Corporation. The officers of Sub immediately prior to the Effective Time shall be the officers of the Surviving Corporation, each to hold office in accordance with the bylaws of the Surviving Corporation.

1.6 Effect on Capital Stock.

(a) At the Effective Time, by virtue of the Merger and without any action on the part of Sub, the Company or any holder of Company Capital Stock, each share of Company Capital Stock issued and outstanding immediately prior to the Effective Time (other than any Dissenting Shares and any shares owned by Parent, the Company or any direct or indirect wholly-owned subsidiary thereof) shall be canceled and extinguished and shall be converted automatically into the right to receive, upon the terms and subject to the conditions set forth below and throughout this Agreement:

(i) in the case of each share of Company Series B Preferred Stock, a number of shares of Parent Class B Common Stock equal to the applicable Series B Exchange Ratio;

(ii) in the case of each share of Company Series A-1 Preferred Stock, a number of shares of Parent Class B Common Stock equal to the applicable Series A-1 Exchange Ratio;

(iii) in the case of each share of Company Series A Preferred Stock, a number of shares of Parent Class B Common Stock equal to the applicable Series A Exchange Ratio; and

-2-

(iv) in the case of each share of Company Common Stock, zero dollars ($0.00), it being understood that each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than any Dissenting Shares) shall be canceled and extinguished without payment of consideration and shall have no further value.

In connection with the conversion of the Company Series B Preferred Stock, Company Series A Preferred Stock, and Company Series A-1 Preferred Stock as provided above, and subject to the conditions set forth herein, including without limitation Section 1.9, Parent will issue 1,231,924 shares of Parent Class B Common Stock in the aggregate (as adjusted for stock splits, stock dividends and the like, the “Merger Consideration”).

(b) Cancellation of Parent-Owned and Company-Owned Stock. Notwithstanding anything expressed or implied to the contrary, each share of Company Capital Stock owned by Parent or the Company or any direct or indirect wholly-owned subsidiary of Parent or the Company immediately prior to the Effective Time shall be automatically canceled and extinguished without any conversion thereof and without any further action on the part of Parent or the Company and shall not be entitled to any portion of the Merger Consideration.

(c) Capital Stock of Sub. At the Effective Time, by virtue of the Merger and without any action on the part of any of the parties hereto, each share of capital stock of Sub issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation. Each stock certificate of Sub evidencing ownership of any such shares shall continue to evidence ownership of shares of capital stock of the Surviving Corporation.

(d) Company Options and Company Stock Plan. All unexpired and unexercised Company Options, Company Warrants and Company Stock Purchase Rights, then outstanding, whether vested or unvested, together with the Plans, shall be canceled and extinguished and shall have no further value.

(e) Company Warrants. All unexpired and unexercised Company Warrants then outstanding, whether vested or unvested, shall be assumed by Parent and then be deemed to be exercisable for the corresponding number of Parent Class B Common Stock that is equal to the number of shares of Series A Preferred Stock issuable upon exercise of such Company Warrant multiplied by the Warrant Exchange Ratio. Following the Merger, the Company Warrants shall have an aggregate exercise price equal to the aggregate exercise price immediately prior to the Effective Time. As soon as reasonably practicable following the Effective Time, Parent shall send a notice to the holders of Company Warrants informing them of the Merger, summarizing the effects thereof, and offering to exchange the Common Warrants for new Parent warrants of substantially like tenor (giving effect to the applicable changes) and describing the warrant exchange procedures therefor.

1.7 Fractional Shares. No fractional share of Parent Class B Common Stock shall be issued in the Merger. In lieu thereof, each holder of shares of Company Capital Stock that would otherwise be entitled to receive a fraction of a share of Parent Class B Common Stock (after aggregating all

-3-

fractional shares of Parent Class B Common Stock to be received by such holder) shall be entitled to receive the nearest whole number of shares of Parent Class B Common Stock (with .5 being rounded up).

1.8 Dissenting Shares.

(a) Notwithstanding any provision of this Agreement to the contrary, any shares of Company Capital Stock held by a holder that has demanded and perfected dissenters’ rights for such shares in accordance with Delaware Law and who, as of the Effective Time, has not effectively withdrawn or lost such dissenters’ rights (“Dissenting Shares”) shall not be converted into or represent the right to receive Parent Capital Stock pursuant to Section 1.6, but the holder thereof shall only be entitled to such rights as are granted by Delaware Law.

(b) Notwithstanding the provisions of Section 1.8(a), if any holder of Dissenting Shares shall effectively withdraw or lose (through failure to perfect or otherwise) his, her or its appraisal or dissenter’s rights, then, as of the later of the Effective Time and the occurrence of such event, such holder’s Dissenting Shares shall then cease to be Dissenting Shares and shall automatically be converted into and represent only the right to receive Parent Capital Stock as provided in Section 1.6, without interest thereon, upon surrender of the certificate representing such shares.

1.9 Escrow of Certain Shares of Parent Class B Common Stock Issued in the Merger.

(a) Second Closing Escrow. Subject to the terms and conditions set forth herein, in the event that a Second Closing (as defined in the Parent Purchase Agreement) may no longer occur (either because such right has expired by its terms or has been irrevocably waived or terminated by the parties) (a “Second Closing Termination Event”), a total of 123,174 shares of Parent Class B Common Stock (the “Second Closing Escrow Shares”) issued in the Merger shall be returned by the holders thereof to Parent. To secure such obligation, Certificates in the names of the applicable Principal Stockholders representing the Second Closing Escrow Shares that are issued pursuant to Section 1.6 above shall be held in escrow by Parent at the Effective Time subject to release as provided herein and will not be delivered to the former holders of Company Capital Stock entitled to receive shares of Parent Class B Common Stock under the terms of this Agreement. Such Second Closing Escrow Shares shall be contributed by the holders of Company Capital Stock receiving shares of Parent Class B Common Stock on a pro rata basis based on the number of shares of Parent Class B Common Stock issued pursuant to Section 1.6. For so long as these shares of Parent Class B Common Stock are held in escrow under this Section 1.9(a), the interests of the holders of Company Capital Stock in the Second Closing Escrow Shares may not be assigned or transferred by such holders. The holders of Company Capital Stock to which the Second Closing Escrow Shares have been allocated shall be entitled to any dividends or other distributions (other than dividends or distributions for which adjustment is made pursuant to the immediately following sentence) with respect to the Second Closing Escrow Shares. Additionally, the Second Closing Escrow Shares shall be appropriately adjusted for any stock splits, stock dividends or the like with respect to such shares. To the full extent that voting rights with respect to Parent Class B Common Stock may exist, the holders of Company Capital Stock to which the Second Closing Escrow Shares have been allocated

-4-

shall have the right to vote the Second Closing Escrow Shares. Upon the occurrence of a Second Closing, the Second Closing Escrow Shares shall be released from escrow and Parent shall deliver the certificates therefor. If a Second Closing Termination Event should occur, all Second Closing Escrow Shares shall be returned to the status of authorized but unissued shares of Parent Capital Stock and the holders of Company Capital Stock shall have no further right to such shares.

(b) Third Closing Escrow. Subject to the terms and conditions set forth herein, in the event that a Third Closing (as defined in the Parent Purchase Agreement) may no longer occur (either because such right has expired by its terms or has been irrevocably waived or terminated by the parties) (a “Third Closing Termination Event”), a total of 73,915 shares of Parent Class B Common Stock (the “Third Closing Escrow Shares”) issued in the Merger shall be returned by the holders thereof to Parent. To secure such obligation, Certificates in the names of the applicable Principal Stockholders representing the Third Closing Escrow Shares that are issued pursuant to Section 1.6 above shall be held in escrow by Parent at the Effective Time subject to release as provided herein and will not be delivered to the former holders of Company Capital Stock entitled to receive shares of Parent Class B Common Stock under the terms of this Agreement. Such Third Closing Escrow Shares shall be contributed by the holders of Company Capital Stock receiving shares of Parent Class B Common Stock on a pro rata basis based on the number of shares of Parent Class B Common Stock issued pursuant to Section 1.6. For so long as these shares of Parent Class B Common Stock, are held in escrow under this Section 1.9(b), the interests of the holders of Company Capital Stock in the Third Closing Escrow Shares may not be assigned or transferred by such holders. The holders of Company Capital Stock to which the Third Closing Escrow Shares have been allocated shall be entitled to any dividends or other distributions (other than dividends or distributions for which adjustment is made pursuant to the immediately following sentence) with respect to the Third Closing Escrow Shares. Additionally, the Third Closing Escrow Shares shall be appropriately adjusted for any stock splits, stock dividends or the like with respect to such shares. To the full extent that voting rights with respect to Parent Class B Common Stock may exist from time to time, the holders of Company Capital Stock to which the Third Closing Escrow Shares have been allocated shall have the right to vote the Third Closing Escrow Shares. Upon the occurrence of a Third Closing, the Third Closing Escrow Shares shall be released from escrow and Parent shall and Parent shall deliver the certificates therefor. If a Third Closing Termination Event should occur, all Third Closing Escrow Shares shall be returned to the status of authorized but unissued shares of Parent Capital Stock and the holders of Company Capital Stock shall have no further right to such shares.

(c) Parent agrees that it will not seek to circumvent its obligations to issue any of the Second Closing Escrow Shares or Third Closing Escrow Shares or to release them (or any of them) from the escrow described above to the former holders of Company Capital Stock by entering into or completing a transaction or transactions on terms that are substantially similar or better to those presently provided for as part of the Second Closing or Third Closing with any person (or affiliate or related party of any person) who presently is a party to the Parent Purchase Agreement and is a potential participant in either such closing.

1.10 Exchange Procedures.

(a) Parent Capital Stock. As promptly as practicable after the Closing Date, Parent shall make available for exchange in accordance with this Article 1 the aggregate number of shares of each of Parent Class B Common Stock issuable in exchange for outstanding shares of Company Capital Stock.

(b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, the Surviving Corporation shall cause to be mailed to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Company Capital Stock (the “Certificates”), (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to Parent and shall be in such form and have such other provisions as Parent may reasonably specify, to include, without limitation, representations as to such holder’s status as an accredited investor and other customary or commercially reasonable investor representations) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the consideration (if any) issuable in exchange therefor pursuant to this Agreement. Upon surrender of a Certificate for cancellation to Parent or to such other agent or agents as may be appointed by Parent together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holder of such Certificate shall be entitled to receive in exchange therefor a certificate representing the number and type of whole shares of Parent Capital Stock to which such holder is entitled pursuant to Section 1.6 (subject to Section 1.9), and the Certificate so surrendered shall be canceled. Until surrendered, each outstanding Certificate that, prior to the Effective Time, represented shares of Company Capital Stock will be deemed from and after the Effective Time, for all corporate purposes other than the payment of dividends, to evidence the ownership of the number and type of whole shares of Parent Capital Stock into which such shares of Company Capital Stock shall have been so converted (including, without limitation, any other shares of capital stock into which such shares may subsequently be or have been converted or exchanged). In the event that the Second Closing or Third Closing occurs, as soon as reasonably practicable following such Second Closing or Third Closing, as applicable, Parent shall issue certificates representing the Second Closing Escrow Shares or Third Closing Escrow Shares, as applicable, to the holders entitled to such shares pursuant to Section 1.9.

(c) Distributions With Respect to Unexchanged Shares of Company Capital Stock. Dividends or other distributions (including, without limitation, stock splits by way of a dividend) with respect to Parent Class B Common Stock that have a record date after the Effective Time shall accrue but shall not be paid to the holder of any unsurrendered Certificate with respect to the shares of Parent Class B Common Stock represented thereby until the holder of record of such Certificate shall surrender such Certificate. Subject to applicable Law, following surrender of any such Certificate, there shall be paid to the record holder of the certificates representing whole shares of Parent Class B Common Stock issued in exchange therefor, without interest, at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore payable (but for the provisions of this Section 1.10(c)) with respect to such whole shares of Parent Class B Common Stock.

-6-

(d) Transfers of Ownership. If any certificate for shares of Parent Class B Common Stock is to be issued pursuant to the Merger in a name other than that in which the Certificate surrendered in exchange therefor is registered, it will be a condition of the issuance thereof that the Certificate so surrendered be properly endorsed and otherwise in proper form for transfer and that the person requesting such exchange will have paid to Parent or any agent designated by it any transfer or other taxes required by reason of the issuance of a certificate for shares of Parent Class B Common Stock in any name other than that of the registered holder of the Certificate surrendered, or that it be established to the satisfaction of Parent or any such agent that such tax has been paid or is not payable.

1.11 No Further Ownership Rights in Company Capital Stock. All shares of Parent Class B Common Stock (or in the case of any Dissenting Shares, any other consideration) issued in exchange of shares of Company Capital Stock in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Company Capital Stock, and there shall be no further registration of transfers on the records of the Company of shares of Company Capital Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article 1

1.12 Lost, Stolen or Destroyed Certificates. Notwithstanding anything herein or otherwise to the contrary, in the event any Certificates evidencing shares of Company Capital Stock shall have been lost, stolen or destroyed, Parent shall issue in exchange for such lost, stolen or destroyed Certificates, upon execution and delivery of a Lost Certificate Affidavit and Indemnity Agreement in substantially the form of Exhibit C, a certificate or certificates representing the shares of Parent Class B Common Stock to which the holder of such shares of Company Capital Stock would be entitled under this Article 1. The execution and delivery of a Lost Certificate Affidavit and Indemnity Agreement as provided for in the immediately preceding sentence will be deemed to be the delivery of a Certificate for all purposes of this Article 1.

1.13 Taking of Necessary Action; Further Action. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right and title to and possession of all assets, property, rights, privileges, powers and franchises of the Company, then except to the extent provided elsewhere herein, officers and directors of the Surviving Corporation are fully authorized to take, and shall take, all such lawful and necessary or desirable action.

(c) To the extent permitted by Law, Parent will indemnify and hold harmless each Company Series B Investor, each of its officers, directors and partners, legal counsel, and accountants and each person controlling such Company Series B Investor within the meaning of Section 15 of the Securities Act, with respect to which registration, qualification, or compliance has been effected pursuant to this Section 5.2, and each underwriter, if any, and each person who controls within the meaning of Section 15 of the Securities Act any underwriter, against all expenses, claims, losses, damages, and liabilities (or actions, proceedings, or settlements in respect thereof) arising out of or based on: (i) any untrue statement (or alleged untrue statement) of a material fact contained or incorporated by reference in any prospectus, offering circular, or other document (including any related registration statement, notification, or the like) incident to any such registration, qualification, or compliance, (ii) any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any violation (or alleged violation) by Parent of the Securities Act, any state securities laws or any rule or regulation thereunder applicable to Parent and relating to action or inaction required of Parent in connection with any offering covered by such registration, qualification, or compliance, and Parent will reimburse each such Company Series B Investor, each of its officers, directors, partners, legal counsel, and accountants and each person controlling such Company Series B Investor, each such underwriter, and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating and defending or settling any such claim, loss, damage, liability, or action; provided that Parent will not be liable in any such case to the extent that any such claim, loss, damage, liability, or action arises out of or is based on any untrue statement or omission based upon written information furnished to Parent by such Company Series B Investor, any of such Company Series B Investor’s officers, directors, partners, legal counsel or accountants, any person controlling such Company Series B Investor, such underwriter or any person who controls any such underwriter and stated to be specifically for use

-21-

therein; and provided, further that, the indemnity agreement contained in this Section 5.2(c) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of Parent (which consent shall not be unreasonably withheld, conditioned or delayed).

(d) To the extent permitted by Law, each Company Series B Investor will, if Parent Capital Stock held by such Company Series B Investor is included in the securities as to which such registration, qualification, or compliance is being effected, indemnify and hold harmless Parent, each of its directors, officers, partners, legal counsel, and accountants and each underwriter, if any, of Parent’s securities covered by such a registration statement, each person who controls Parent or such underwriter within the meaning of Section 15 of the Securities Act, each other such Company Series B Investor, and each of their officers, directors, and partners, and each person controlling such Company Series B Investor, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on: (i) any untrue statement (or alleged untrue statement) of a material fact contained or incorporated by reference in any such registration statement, prospectus, offering circular, or other document, or (ii) any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse Parent and such Company Series B Investors, directors, officers, partners, legal counsel, and accountants, persons, underwriters, or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability, or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular, or other document in reliance upon and in conformity with written information furnished to Parent by such Company Series B Investor and stated to be specifically for use therein; provided, however, that the obligations of such Holder hereunder shall not apply to amounts paid in settlement of any such claims, losses, damages, or liabilities (or actions in respect thereof) if such settlement is effected without the consent of such Company Series B Investor (which consent shall not be unreasonably withheld, conditioned or delayed); and provided that in no event shall any indemnity under this Section 5.2(d) exceed the net proceeds from the offering received by such Company Series B Investor.

(e) Each party entitled to indemnification under this Section 5.2 (the “Registration Indemnified Party”) shall give notice to the party required to provide indemnification (the “Registration Indemnifying Party”) promptly after such Registration Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Registration Indemnifying Party to assume the defense of such claim or any litigation resulting therefrom; provided that counsel for the Registration Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld), and the Registration Indemnified Party may participate in such defense at such party’s expense; and provided further that the failure of any Registration Indemnified Party to give notice as provided herein shall not relieve the Registration Indemnifying Party of its obligations under this Section 5.2, to the extent such failure is not prejudicial. No Registration Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Registration Indemnified Party, consent to entry of any judgment or

-22-

enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. Each Registration Indemnified Party shall furnish such information regarding itself or the claim in question as a Registration Indemnifying Party may reasonably request in writing and as shall be reasonably required in connection with defense of such claim and litigation resulting therefrom.

(f) Parent shall keep any registration on Form S-3 effective until the earliest of (i) sixty (60) days following the effective date of the registration statement, (ii) such time as all shares registered thereunder have been sold or (iii) such time as the holders whose shares are registered on such Form S-3 agree to terminate such registration. Parent agrees that it will use commercially reasonable efforts to (x) obtain eligibility to use Form S-3 in accordance with SEC rules and regulations and (y) maintain and continue such eligibility such that the Company Series B Investors may enjoy the benefits of the registration rights provided under this Section 5.2.

(g) If (i) in the good faith judgment of the board of directors of Parent (the “Parent Board”), the filing of a registration statement pursuant to this Section 5.2 would be detrimental to Parent and the Parent Board concludes, as a result, that it is in the best interests of Parent to defer the filing of such registration statement at such time, and (ii) Parent shall furnish to such Company Series B Investors a certificate signed by the President of Parent stating that in the good faith judgment of the Parent Board, it would be detrimental to Parent for such registration statement to be filed in the near future and that it is, therefore, in the best interests of Parent to defer the filing of such registration statement, then (in addition to the limitations set forth in Section 5.2(a) above) Parent shall have the right to defer such filing for a period of not more than ninety (90) days after receipt of the request of the Company Series B Investors, and, provided further, that Parent shall not defer its obligation in this manner more than once in any twelve (12)-month period.

5.3 Market Standoff Agreements. Each Principal Stockholder receiving Parent Class B Common Stock pursuant to this Agreement agrees to execute a lock-up agreement with Parent in substantially the form attached hereto as Exhibit D (the “LUA”) pursuant to which such holders shall agree, if so requested by Parent or any underwriter’s representative in connection with an IPO, not to sell or otherwise transfer any securities of Parent during a period of up to one hundred eighty (180) days following the effective date of the registration statement, or such other period as specified in any lock-up agreement approved by Parent and its underwriters in connection with an IPO. Notwithstanding the foregoing, if any other stockholders of Parent are offered the opportunity to enter into a different lock-up agreement that contains terms or provisions that are materially more favorable to such stockholders (a “Preferential LUA”) than those contained in the LUA entered into or to be entered into by any Principal Stockholder hereunder, then each such Principal Stockholder shall be entitled at its option to enter into such Preferential LUA as well prior to the IPO.

5.4 Cooperation in Qualified IPO. Each Principal Stockholder receiving Parent Class B Common Stock pursuant to this Agreement agrees to take such other commercially reasonable actions as may be reasonably necessary to effectuate a Qualified IPO, including without limitation executing and delivering any stockholder consents, questionnaires, lock-up agreements (but in this

-23-

case subject to Section 5.3, above) and certificates reasonably requested by Parent or its underwriters, but only if and to the extent that such actions, consents, and the like do not contain terms that provide disparate treatment to the holders of Parent Class B Common Stock from those actions and consents required of Parent’s other stockholders.

5.5 Expenses. Except as otherwise provided herein, whether or not the Merger is consummated, all fees and expenses incurred in connection with the Merger including all legal, accounting, financial advisory, consulting and all other fees and expenses of third parties incurred by a party in connection with the negotiation and effectuation of the terms and conditions of this Agreement and the transactions contemplated hereby, shall be the obligation of the respective party incurring such fees and expenses, provided, however, that the Company shall pay the reasonable legal fees and expenses incurred by DLA ▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇ US LLP in its capacity as counsel for the Company, which fees shall not exceed $40,000.

5.6 Additional Documents and Further Assurances. Each party hereto, at the request of another party hereto, shall execute and deliver such other instruments and do and perform such other acts and things as may be necessary or desirable for effecting completely the consummation of this Agreement and the transactions contemplated hereby.

5.7 Indemnification. From and after the Effective Time, Parent shall (or shall cause the Surviving Corporation to) fulfill and honor in all respects the obligations of the Company to indemnity each Person who is or was a director or officer of the Company pursuant to any indemnification provisions of the Company’s charter or bylaws as in effect immediately prior to the Effective Time.

5.8 Certain Employee and Benefits Matters. Those employees of the Company who are hired by Parent or any of its affiliates will be full given credit for their service and tenure with the Company with respect to vacation accruals, non-applicability of waiting periods for Company benefits (insurance, participation in 401(k) plan and the like. Those employees of the Company who are not hired by Parent or its affiliates will be any and all accrued or otherwise applicable severance, accrued vacation and the like, in accordance with the Company’s historical practices and procedures.

5.9 Information Rights.

(a) Access to Records; Inspection. Each Principal Stockholder who receives at least 30,000 shares of Parent Class B Common Stock pursuant to this Agreement (each, a “Significant Holder”) shall have the right to visit and inspect any of the properties of Parent and to discuss the affairs, finances and accounts of Parent with its officers, and to review such information as is reasonably requested all during normal business hours. Parent shall make its officers available to the Significant Holders during all such visits and inspections. The Significant Holders agree to keep, and to use the same degree of care as such Significant Holders use to protect their own confidential information, confidential and not misuse any Parent information that Parent identifies as being confidential or proprietary (so long as such information is not in the public domain) that is obtained by a Significant Holder, except that a Significant Holder may disclose such proprietary or confidential information (i) to any partner, subsidiary, parent or such other agent of such Significant

- 24 -

Holder for the purpose of evaluating its ownership position in Parent as long as such partner, subsidiary, parent or agent is advised of and bound to the confidentiality provisions of this Agreement; (ii) at such time as it enters the public domain through not fault of such Significant Holder; (iii) that is communicated to it free of any obligation of confidentiality; or (iv) that is developed by such Significant Holder or its agents independently of and without reference to any confidential information communicated by Parent.

(b) Financials. As soon as reasonably practicable after the end of each quarterly accounting periods in each fiscal year of Parent, Parent will furnish to each Significant Holder, upon request from such Significant Holder, an unaudited consolidated balance sheet of Parent as of the end of each such quarterly period, and an unaudited consolidated statement of income and an unaudited statement of cash flows of Parent for such period and for the current fiscal year to date, prepared in accordance with GAAP (with the exception that no notes need be attached to such statements and period-end audit adjustments may not have been made).

ARTICLE 6

SURVIVAL OF REPRESENTATIONS AND WARRANTIES

6.1 Survival of Representations, Warranties and Covenants. All of the representations, warranties and covenants in this Agreement of the Company and the Principal Stockholders on the one hand, and Parent and Sub on the other hand, shall survive the Merger and continue until 5:00 p.m., Virginia time, on the date which is one year following the Closing Date (the “Expiration Date”); provided, however, that (a) the representations and warranties of the Company set forth in Sections 2.1 and 2.4 of this Agreement shall survive indefinitely and (b) the representations and warranties of the Company set forth in Sections 2.14 and 2.19 of this Agreement shall survive until the expiration of the applicable statutes of limitation.

6.2 Indemnification by the Principal Stockholders and the Company. Subject to the restrictions and limitations set forth elsewhere herein, the Principal Stockholders, severally but not jointly, in proportion to their respective Indemnification Pro Rata Shares, shall indemnify and hold harmless Parent and its officers, directors, employees, agents, Representatives and affiliates, including the Surviving Corporation after the Closing (Parent and such other persons, collectively, the “Parent Indemnified Parties”), against all Losses incurred directly or indirectly by one or more Parent Indemnified Parties as a result of (a) any inaccuracy or breach of any representation or warranty of the Company contained herein or (b) any failure by the Company prior to Closing or any failure by the Principal Stockholders to perform or comply with any covenant contained herein, provided, however, that no Principal Stockholder will be liable or responsible for, or have any indemnification obligations in respect of, any other Principal Stockholder’s breach of any covenant contained herein. No Principal Stockholder shall have any right of contribution from Parent or the Surviving Corporation with respect to any Loss claimed by Parent Indemnified Parties.

6.3 Claims for Indemnification.

(a) Upon receipt by a Principal Stockholder of a certificate signed by any officer of Parent (an “Officer’s Certificate”): (i) stating that Parent Indemnified Parties have paid or properly

-25-

accrued or reasonably anticipate that they will have to pay or accrue Losses, and (ii) specifying in reasonable detail the individual items of Losses included in the amount so stated, the date each such item was paid or properly accrued or the basis for such anticipated liability, and the nature of the misrepresentation or breach of warranty (which shall be based upon a representation or warranty of the Company that shall not have terminated as of the date such Officer’s Certificate is delivered to such Principal Stockholder) to which such item is related, such Principal Stockholder shall, subject to the provisions of Sections 6.3(b) and 6.4 hereof, deliver to Parent, as promptly as practicable, cash or Parent Capital Stock in an amount equal to such Losses, and Parent shall deliver such cash or Parent Capital Stock to such Parent Indemnified Parties as appropriate. Parent shall deliver an Officer’s Certificate concurrently to each Principal Stockholder from whom Parent intends to seek indemnification for the Losses specified in such Officers Certificates. If Parent shall not have delivered an Officer’s Certificate regarding such Losses to a Principal Stockholder within thirty (30) days of the delivery of the first Officer’s Certificate for such Losses, Parent shall not be entitled to seek indemnification hereunder for such Losses from such Principal Stockholder.

(b) A Principal Stockholder, at its option, may elect to satisfy Losses claimed under Section 6.3 by delivering cash, Parent Capital Stock or any combination thereof to Parent. For the purpose of determining the number of shares of Parent Capital Stock to be delivered to Parent pursuant to this Section 6.3, each share of Parent Capital Stock shall be valued at either (i) if publicly traded and listed or admitted for trading on any exchange or market (including, without limitation, Nasdaq or the NYSE) or traded over-the-counter, then the value shall be deemed to be the average of the closing bid or sale prices (whichever are applicable) over the ten (10)-day period ending three (3) trading days prior to the date of such delivery or (ii) otherwise, the Implied Share Price.

6.4 Objections to Claims; Resolution of Conflicts; Arbitration.

(a) Objections to Claims. Each Principal Stockholder shall be entitled, during the thirty-day period following the time of delivery of any Officer’s Certificate to such Principal Stockholder, to object to the claim made in such Officer’s Certificate by delivering a written statement of such objection to Parent. After the expiration of such thirty (30)-day period, provided that no such written statement of objection shall have been delivered to Parent, such Principal Stockholder shall make delivery of cash and/or shares of Parent Capital Stock to Parent in accordance with Section 6.3 hereof.

(b) Disputed Claims. In case a Principal Stockholder objects in writing to any claim or claims made in any Officer’s Certificate, Parent and each Principal Stockholder to whom an Officer’s Certificate shall have been delivered (and who shall not previously have satisfied such claim or claims) shall attempt in good faith to agree upon the rights of the respective parties with respect to each of such claims. If Parent and each such Principal Stockholder should so agree, a memorandum setting forth such agreement shall be prepared and signed by the parties. Such Principal Stockholder shall be entitled to rely on any such memorandum and deliver cash and/or shares of Parent Capital Stock to Parent in accordance with the terms thereof.

-26-

(i) If no agreement can be reached after the good faith negotiation contemplated by Section 6.4(b), any party to such negotiation may demand arbitration of the matter unless the amount of the damage or loss is at issue in pending litigation with a third party, in which event arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration; and in either such event the matter shall be settled by arbitration conducted by three arbitrators. Each party to such negotiation (with all Principal Stockholders treated for this purpose as one party) shall select one arbitrator, and the two arbitrators so selected shall select a third arbitrator. The arbitrators shall set a limited time period and establish procedures designed to reduce and minimize to the fullest extent practicable the cost and time for discovery while allowing the parties an opportunity, adequate in the sole judgment of the arbitrators, to discover relevant information from the opposing parties about the subject matter of the dispute. The arbitrators shall rule upon motions to compel or limit discovery and shall have the authority to impose sanctions, including attorneys’ fees and costs, to the same extent as a court of law or equity of competent jurisdiction, should the arbitrators determine that discovery was sought without substantial justification or that discovery was refused or objected to without substantial justification. The decision of a majority of the three arbitrators as to the validity and amount of any claim in such Officer’s Certificate shall be binding and conclusive upon the parties to this Agreement. Such decision shall be written and shall be supported by written findings of fact and conclusions that shall set forth the award, judgment, decree or order awarded by the arbitrators. Notwithstanding anything herein or otherwise to the contrary, the arbitrators shall (x) have no right or authority to award damages or costs against any person that exceed the limitations applicable to such person in accordance with the provisions of Section 6.6, or to award damages or costs that otherwise are not allocable to such person in pursuant to Section 6.2, and (y) describe the basis for any decision or award in reasonable detail.

(ii) Judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction. Any such arbitration shall be held under the rules then in effect of the American Arbitration Association.

6.5 Third-Party Claims. In the event Parent becomes aware of a third-party claim which Parent believes may result in a claim for indemnification under Section 6.3, Parent shall notify the Principal Stockholders of such claim, and one representative of the Principal Stockholders (which representative would be designated from time to time by, and serve in such role at the pleasure of, a majority in interest of the Principal Stockholders, measured by shares of Parent Class B Common Stock issuable to the Principal Stockholders at the Effective Time) shall be entitled, at the expense of the Principal Stockholders, to participate in, but not to determine or conduct, any defense of such claim. Parent shall have the right in its sole discretion to settle any such claim; provided, however, that except with the consent of the representative of the Principal Stockholders (which consent shall not be unreasonably withheld or delayed), no settlement of any such claim with third-party claimants shall alone be determinative of the amount payable by any Principal Stockholder as a result of any claim for indemnification under Section 6.3. In the event that the representative of the Principal Stockholders shall have consented to any such settlement, no Principal Stockholder shall have any power or authority to object under any provision of this Article 6 to the amount of any claim by Parent against such Principal Stockholder with respect to such settlement.

-27-

6.6 Limitations; Maximum Payments; Remedies.

(a) Notwithstanding anything herein or otherwise to the contrary, neither Parent nor any of the other Parent Indemnified Parties may seek indemnification with respect to any claim for Losses until the aggregate amount of all Losses for which indemnification under this Article 6 is sought exceeds $150,000 (the “Minimum Claims Amount”), whereupon Parent and such other Parent Indemnified Parties shall be entitled to seek indemnification with respect to all such Losses without regard to the Minimum Claims Amount from the first dollar of such Losses, subject to the limitations set forth in Section 6.6(b), provided, however, that no Parent Indemnified Party (other than Parent) shall be entitled or permitted to seek indemnification under this Article 6 unless Parent shall have consented in writing, in Parent’s sole discretion, to the assertion of such claim by such other Parent Indemnified Party.

(b) Except in the case of fraud, the maximum liability of each Principal Stockholder for his, her or its indemnification obligations pursuant to this Article 6 shall be limited to sixty percent (60%) of such Principal Stockholders’ Indemnification Pro Rata Share of the Merger Consideration, provided, however, that notwithstanding the foregoing, the liability of the Principal Stockholders for their indemnification obligations pursuant to this Article 6 shall be limited to one hundred percent (100%) of their Indemnification Pro Rata Share of the Merger Consideration with respect to breaches of the Company of the representations and warranties made in Section 2.11 hereof, provided, however, that for purposes of clarity, except in the case of fraud, in no event will the foregoing provisions be read to provide for indemnification in excess of one hundred percent (100%) of the respective Principal Stockholders’ Indemnification Pro Rata Share of the Merger Consideration. The indemnification rights of Parent and the other Parent Indemnified Parties provided for in this Article 6 shall be, except in the case of fraud, the sole and exclusive remedy available to them (or any person claiming through them) for any Losses that such persons (or any person claiming through them) have now or may have in the future, of any kind or nature whatsoever, whether in law, at equity or otherwise, and whether know or unknown, including, without limitation, any Losses attributable to any inaccuracy in or breach of any representation or warranty, any failure to perform any of the covenants, agreements or undertakings in this Agreement, the Company Disclosure Schedule, or as part of or in connection with any agreement or any other document provided for in or contemplated by this Agreement. For purposes of this Section 6, the number of shares constituting the “Merger Consideration” shall be adjusted and reduced as appropriate in the event of a Second Closing Termination Event or a Third Closing Termination Event by the number of shares of Parent Class B Common Stock cancelled by Parent upon such events.
