ARTICLE II

Effect of the Merger on the Capital Stock of the
Constituent Corporations; Exchange of Certificates

          SECTION 2.1. Effect on Capital Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares (the “Shares”) of common stock, par value $1.00 per share, of Ntera (“Ntera Common Stock"):

          (a) Cancellation of Treasury Stock. Each share of Ntera Common Stock that is owned by Ntera or by any subsidiary of Ntera shall automatically be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor.

          (b) Conversion of Company Common Stock. Except as set forth in Section 2.2(a) and subject to Section 2.3, each issued and outstanding share of Ntera Common Stock shall be converted into the right to receive such number of fully paid and nonassessable shares of WorldQuest Common Stock (rounded up to the nearest whole number of shares) as is equal to the Exchange Ratio (the “Merger Consideration”). As of the Effective Time, all such shares of Ntera Common Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such shares of Ntera Common Stock shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration upon surrender of such certificate in accordance with Section 2.2(a). For purposes of this Agreement, “Exchange Ratio” means the quotient obtained by dividing (i) the difference obtained by subtracting (A) the number of shares of Fully Diluted WorldQuest Common Stock immediately prior to the Effective Time from (B) the quotient obtained by dividing the number of shares of Fully Diluted WorldQuest Common Stock immediately prior to the Effective Time by .20, by (ii) the total number of shares of Ntera Common Stock outstanding immediately prior to the Effective Time. In order to avoid confusion, an illustration of the calculation of the Exchange Ratio is set forth on Section 2.1 of the WorldQuest Disclosure Schedule (as defined below). For purposes of this Agreement, the term “Fully-Diluted WorldQuest Common Stock” shall mean all of the outstanding WorldQuest Common Stock, assuming conversion or exchange of all outstanding securities that are convertible into or exchangeable for WorldQuest Common Stock, including all warrants and stock options provided that such securities are then “in the money.” For purposes of this Section 2.1(b), a convertible security shall be considered “in the money” if, the exercise price per share for such option or warrant is less than $6.00 (as adjusted for any stock split, combination or similar corporate event after the date hereof).

          SECTION 2.2. Exchange of Certificates.

          (a) Exchange Procedure. At the Closing, subject to Section 2.3, each holder of record of a certificate or certificates that immediately prior to the Effective Time represented shares of Ntera Common Stock (the “Certificates”) shall surrender the Certificates held by such holder in such form as WorldQuest may reasonably specify in exchange for the Merger Consideration. Subject to Section 2.3, upon surrender of a Certificate for cancellation together with such other

7

documents as may reasonably be required by WorldQuest, the holder of such Certificate shall receive in exchange therefor, and the Surviving Corporation shall pay the Merger Consideration for each share of Ntera Common Stock formerly evidenced by such Certificate, and such Certificate shall thereupon be canceled. If payment of the Merger Consideration is to be made to a person other than the person in whose name the surrendered Certificate is registered on the stock transfer books of Ntera, it shall be a condition of payment to the holder of a Certificate that it be endorsed properly or otherwise be in proper form for transfer and that the person requesting such payment shall have paid all transfer and other taxes required by reason of the payment of the Merger Consideration to a person other than the registered holder thereof or shall have established to the satisfaction of the Surviving Corporation that such taxes are not applicable.

          (b) No Liability. Notwithstanding anything to the contrary in this Section 2.2 neither the Surviving Corporation nor any party hereto shall be liable to a holder of shares of Ntera Common Stock for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law.

          (c) No Further Ownership Rights in Ntera Common Stock. All Merger Consideration paid upon the surrender of Certificates in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Ntera Common Stock represented by such Certificates, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Ntera Common Stock which were outstanding immediately prior to the Effective Time.

          SECTION 2.3. Holdback of Shares.

          (a) At Closing, notwithstanding any other provision of this Article II, upon the surrender of Certificates in accordance with the terms of this Article II, the Surviving Corporation shall hold back a number of shares of WorldQuest Common Stock equal to 15% of the aggregate Merger Consideration for all of the shares of Ntera Common Stock (rounded to the nearest whole number of shares) (the “Holdback Shares”), including any shares issued to a former holder that is not a Participating Stockholder (as defined below). The Holdback Shares shall be held back on a pro rata basis from the Merger Consideration issuable to all holders of Ntera Common Stock other than the holder identified on Section 2.3(a) of the Ntera Disclosure Schedule (the “Participating Stockholders”). The Holdback Shares shall be held by the Surviving Corporation for a period (the “Holdback Period”) beginning on the Closing Date through the Final Determination Date (as defined below).

          (b) Within 30 days of the end of the twelve month period (the "Determination Period”) beginning on the first day of the month immediately following the Closing Date, the Surviving Corporation shall cause its auditors, at the Surviving Corporation’s expense, to prepare and deliver to the Surviving Corporation and the Principal Shareholder, as the representative of the Participating Stockholders, its calculation of the Surviving Corporation’s earnings before interest, taxes, depreciation and amortization (“EBITDA”) during the Determination Period. The calculation of EBITDA shall be prepared by the auditors in accordance with the procedures set forth on Section 2.3(b) of the Ntera Disclosure Schedule. The Surviving Corporation shall give the Principal

8

Shareholder access to the Surviving Corporation’s books and records and the supporting documentation for the calculations of the auditors reasonably necessary for the Principal Shareholder to review and confirm the calculation of the auditors. In the event that the Principal Shareholder disputes the correctness of the calculation of EBITDA, the Principal Shareholder shall notify the Surviving Corporation and its auditors within 20 business days after receipt of the calculation and shall set forth, in writing and in reasonable detail, the reason for the Principal Shareholder’s objections. If the Principal Shareholder fails to deliver a notice of objections within 20 business days after receipt of the calculation from the Surviving Corporation’s auditors, the Principal Shareholder shall be deemed to have accepted the calculation. The Surviving Corporation and the Principal Shareholder shall endeavor in good faith to resolve any disputed matters within 20 business days after receipt by the Surviving Corporation of the Principal Shareholder’s notice of objections. If the parties are unable to resolve the disputed matters, they shall jointly select a nationally known independent accounting firm (which firm shall not be the then regular auditors of the Surviving Corporation) to resolve the matters in dispute, and the determination of such firm in respect of the correctness of each matter remaining in dispute shall, except as described in Section 2.3(b) of the Ntera Disclosure Schedule, be conclusive and binding. The date on which a final determination of EBITDA is made, whether by acceptance of the initial calculation or resolution of any disputes, is herein referred to as the “Final Determination Date.”

          (c) If the ultimate calculation of EBITDA is equal to $8,500,000 or more (the “Target Amount”), then the Surviving Corporation shall release to the Participating Stockholders (less any Holdback Shares cancelled in accordance with Section 9.5), together with all dividends and distributions declared thereon during the Holdback Period, within three business days of the Final Determination Date. If the ultimate calculation of EBITDA is less than the Target Amount, then any remaining Holdback Shares shall automatically be forfeited, canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor, and the Surviving Corporation shall retain any dividends declared thereon during the Holdback Period.

          (d) During the Holdback Period, each Participating Stockholder may exercise any and all voting and other consensual rights pertaining to such holder’s Holdback Shares (other than any Holdback Shares that are cancelled in accordance with Section 9.5). During the Holdback Period, the Surviving Corporation shall retain all dividends and distributions paid or payable in respect of the Holdback Shares (other than any Holdback Shares that are cancelled in accordance with Section 9.5) for the benefit of such holders and in the event the Target Amount is met, such dividends and distributions will be paid to such holders in accordance with Section 2.3(c) above. The Holdback Shares shall be subject to adjustment to take into account any stock split, stock dividend, recapitalization or other similar event effecting the capital stock of the Surviving Corporation.

Except for the capital stock of its subsidiaries, Ntera does not own, directly or indirectly, any capital stock or other ownership interest in any person.

               (G) With respect to each Ntera Employee Benefit Plan that is not subject to United States law (a “Foreign Benefit Plan”): (i) all employer and employee contributions to each Foreign Benefit Plan required by law or by the terms of such Foreign Benefit Plan have been made, or, if applicable, accrued in accordance with normal accounting practices and a pro rata contribution for the period prior to and including the Effective Time has been made or accrued; (ii) the fair market value of the assets of each funded Foreign Benefit Plan, the liability of each insurer for any Foreign Benefit Plan funded through insurance or the book reserve established for any Foreign Benefit Plan, together with any accrued contributions, is sufficient to procure or provide for the benefits determined on any ongoing basis (actual or contingent) accrued to the Effective Time with respect to all current and former participants under such Foreign Benefit Plan according to the actuarial assumptions and valuations most recently used to determine employer contributions to such Foreign Benefit Plan, and none of the Transactions shall cause such assets or insurance obligations to be less than such benefit obligations; and (iii) each Foreign Benefit Plan required to be registered has been registered and has been maintained in good standing with applicable regulatory authorities. Each Foreign Benefit Plan is now and always has been operated in full compliance with all applicable non-United States laws.

               (H) No Ntera Employee Benefit Plan provides, nor does Ntera, or any Ntera Affiliate have an obligation to provide, medical, life or other welfare benefits (whether or not insured) with respect to current or former employees after retirement or other termination of service, other than as required pursuant to Section 4980B of the Code.

               (I) At the effective time, each outstanding option to purchase WorldQuest Common Stock, whether or not granted under the WorldQuest Networks, Inc. 2002 Stock Option Plan, shall by virtue of the Merger be assumed by WorldQuest in its capacity as the Surviving Corporation. Each option so assumed under this Agreement will continue to have, and be subject to the same terms and conditions of such options immediately prior to the Effective Time.

All such tax returns are correct and

15

complete in all material respects. All taxes shown as due and payable on the Tax Returns have been paid and all other taxes of Ntera or any of its subsidiaries have been adequately reserved for in the Ntera Financial Statements. There are no Liens on any of the assets of Ntera or any of its subsidiaries that arose in connection with any failure (or alleged failure) to timely pay any tax.

               (ii) No dispute or claim concerning any tax liability of Ntera or any of its subsidiaries has been proposed or claimed in writing or, to the knowledge of Ntera or the Principal Shareholder, threatened by any authority.

               (iii) Neither Ntera nor any of its subsidiaries has waived any statute of limitations in respect of taxes or agreed to any extension of time with respect to a tax assessment or deficiency.

To the knowledge of Ntera, Ntera and its subsidiaries own or have a valid right to use all Intellectual Property (as defined in this Section 3.1(l)) that is individually or in the aggregate material to the conduct of the businesses of Ntera and its subsidiaries (the "Ntera Intellectual Property”), except where the failure to so own or have a valid right to use such Ntera Intellectual Property would not, individually or in the aggregate, be reasonably likely to have a Ntera Material Adverse Effect. Neither Ntera nor any of its subsidiaries is or is alleged to be in default (or with the giving of notice or lapse of time or both, would be in default) in any material respect under any license to use Ntera Intellectual Property, and to the

16

knowledge of Ntera, neither Ntera nor any subsidiary of Ntera is infringing any Intellectual Property of any third party, except for such defaults and infringements which, individually or in the aggregate, would not reasonably be expected to have a Ntera Material Adverse Effect. There are no (i) circumstances which, with the giving of notice or the lapse of time, or both, or the failure of Ntera to act in a timely fashion, would cause the loss or materially impair the validity of any Ntera Intellectual Property, or (ii) notices of any material claim of infringement with respect to any item of Ntera Intellectual Property, or notices of any contested patent or other contested item of Ntera Intellectual Property, except for such circumstances or notices which individually or in the aggregate would not reasonably be expected to have a Ntera Material Adverse Effect.

          (n) Change of Control. Except as described in Section 3.1(n) of the Ntera Disclosure Schedule, the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby will not (i) result in any payment (including severance, unemployment compensation, tax gross-up, bonus or otherwise) becoming due to any current or former director, employee or independent contractor of Ntera or any of its subsidiaries, from Ntera or any of its subsidiaries under any Stock Plan, benefit plan, agreement or otherwise, (ii) materially increase any benefits otherwise payable under any Stock Plan, benefit plan, agreement or otherwise or (iii) result in the acceleration of the time of payment, exercise or vesting of any such benefits.

          SECTION 3.2. Representations and Warranties of WorldQuest. Except as set forth in the written disclosure schedule dated as of the date of this Agreement and previously delivered by WorldQuest to Ntera (the “WorldQuest Disclosure Schedule”) (it being understood that the WorldQuest Disclosure Schedule shall be arranged in sections corresponding to the sections contained in this Agreement, and the disclosures in any section of the WorldQuest Disclosure Schedule shall qualify all of the representations and warranties in the corresponding sections of this Section 3.2 and, in addition, all other sections in this Section 3.2 to the extent it is reasonably clear from a reading of the disclosure that such disclosure is applicable to such other sections), WorldQuest represents and warrants to Ntera as follows:

          (a) Organization, Standing and Corporate Power. WorldQuest is a corporation duly organized, validly existing and in good standing under the laws of the state of Delaware and has the requisite corporate power and authority to carry on its business as now being conducted.

20

WorldQuest is duly qualified or licensed to do business and is in good standing in each jurisdiction in which the nature of its business or the ownership or leasing of its properties makes such qualification or licensing necessary, other than in such jurisdictions where the failure to be so qualified or licensed (individually or in the aggregate) would not reasonably be expected to have a material adverse effect on the financial condition, business, assets or results of operations of WorldQuest and its subsidiaries taken as a whole except that occurrences due solely to a disruption of WorldQuest’s or its subsidiaries’ business solely as a result of the announcement of the execution of this Agreement and the transactions proposed to be consummated hereunder shall be excluded from consideration for purposes of determining the existence of a material adverse effect on WorldQuest and its subsidiaries taken as a whole (a "WorldQuest Material Adverse Effect”). WorldQuest has provided Ntera with complete and correct copies of its certificate of incorporation and by-laws.

          (b) Subsidiaries. Section 3.2(b) of the WorldQuest Disclosure Schedule lists each subsidiary of WorldQuest and its respective jurisdiction of incorporation. All the outstanding shares of capital stock of each such subsidiary have been validly issued and are fully paid and nonassessable and are owned by WorldQuest, by another subsidiary of WorldQuest or by WorldQuest and another such subsidiary, free and clear of all Liens and free of any other limitation or restriction (including any restriction on the right to vote, sell or otherwise dispose of such capital stock). Except for the capital stock of its subsidiaries, WorldQuest does not own, directly or indirectly, any capital stock or other ownership interest in any person.

          (c) Capital Structure. As of the date of this Agreement, the authorized capital stock of WorldQuest consists of 50,000,000 shares of WorldQuest Common Stock and 10,000,000 shares of preferred stock, par value $.01 per share (“WorldQuest Preferred Stock”). At the close of business on March 15, 2004, (i) 6,466,399 shares of WorldQuest Common Stock were issued and outstanding, (ii) no shares of WorldQuest Preferred Stock were issued and outstanding, (iii) no shares of WorldQuest Common Stock were held by WorldQuest in its treasury, (iv) approximately 783,086 shares of WorldQuest Common Stock were reserved for future issuance pursuant to WorldQuest’s various stock option and stock purchase plans described in, or incorporated by reference in, the WorldQuest SEC Documents (defined below in Section 3.2(e)) and (v) 720,775 shares of WorldQuest Common Stock were subject to issuance upon exercise of outstanding warrants to purchase WorldQuest Common Stock (“WorldQuest Warrants”). 963,981 of the WorldQuest Warrants and the outstanding options to purchase WorldQuest Common Stock were “in the money” (as defined in Section 2.1(b)) as of the date hereof. Except as set forth above, at the close of business on March 15, 2004, no shares of capital stock or other voting securities of WorldQuest were issued, reserved for issuance or outstanding. All outstanding shares of capital stock of WorldQuest are, and all shares which may be issued pursuant to this Agreement will be, when issued, duly authorized, validly issued, fully paid and nonassessable and not subject to preemptive rights. As of the date of this Agreement, there are outstanding no bonds, debentures, notes or other indebtedness of WorldQuest having the right to vote (or convertible into, or exchangeable for, securities having the right to vote) on any matters on which stockholders of WorldQuest may vote. As of the date of this Agreement there are outstanding no securities of WorldQuest which contain any anti-dilution provisions that would be triggered by the transactions

21

contemplated by this Agreement or that are based upon the issue price of any securities of WorldQuest.

          (d) Authority; Noncontravention. WorldQuest has the requisite corporate power and authority to enter into this Agreement and, subject to the approval of this Agreement by the affirmative votes of the holders of a majority of the outstanding shares of WorldQuest Common Stock (the “WorldQuest Shareholder Vote”) with respect to the Merger and the issuance of WorldQuest Common Stock, to consummate the transactions contemplated by this Agreement. The execution and delivery of this Agreement by WorldQuest and the consummation by WorldQuest of the transactions contemplated by this Agreement have been duly authorized by all necessary corporate action on the part of WorldQuest, subject, in the case of the Merger if required under Delaware Law, and in the case of the issuance of WorldQuest Common Stock if required by the rules of The Nasdaq Stock Market (“Nasdaq”), to approval of this Agreement by the WorldQuest Shareholder Vote. This Agreement has been duly executed and delivered by WorldQuest and constitutes a valid and binding obligation of WorldQuest, enforceable against it in accordance with its terms, except as enforceability may be limited by any applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditor’s rights generally and the application of general principals of equity (regardless of whether that enforceability is considered in a proceeding at law or in equity). The execution and delivery of this Agreement does not, and the consummation of the transactions contemplated by this Agreement and compliance with the provisions of this Agreement will not, conflict with, or result in any violation of, or default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation or acceleration of any obligation or to loss of a material benefit under, or result in the creation of any Lien upon any of the properties or assets of WorldQuest or any of its subsidiaries under, (i) the certificate of incorporation or by-laws of WorldQuest, (ii) any loan or credit agreement, note, bond, mortgage, indenture, lease or other agreement, instrument, permit, concession, franchise or license applicable to WorldQuest or any of its subsidiaries or their respective properties or assets or (iii) subject to the governmental filings and other matters referred to in the following sentence, any judgment, order, decree, statute, law, ordinance, rule or regulation applicable to WorldQuest or any subsidiary of WorldQuest or their respective properties or assets, other than, in the case of clause (ii) or (iii), any such conflicts, violations, defaults, rights, losses or Liens that individually or in the aggregate would not reasonably be expected to have a WorldQuest Material Adverse Effect. No Consent is required by or with respect to WorldQuest in connection with the execution and delivery by WorldQuest of this Agreement or the consummation by WorldQuest of the transactions contemplated by this Agreement, except for (i) if required, the filing of a premerger notification and report form by WorldQuest under the HSR Act and any applicable filings under similar foreign antitrust or competition laws and regulations, (ii) the filing with the SEC of (A) a proxy statement in preliminary and definitive form relating to the WorldQuest Stockholders Meeting (as defined below) (as amended and supplemented from time to time, the “WorldQuest Proxy Statement”), and (B) such reports under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) as may be required in connection with this Agreement and the transactions contemplated hereby, (iii) such filings as may be required under state securities or “blue sky” laws, (iv) the filing of the Certificate of Merger with the Delaware Secretary of State and appropriate documents with the relevant authorities of other states in which Ntera is qualified to do

          (e) SEC Documents; Financial Statements; No Undisclosed Liabilities. WorldQuest has filed all required reports, forms and other documents with the SEC since January 1, 2001 (the “WorldQuest SEC Documents”). As of their respective dates, the WorldQuest SEC Documents complied in all material respects with the requirements of the Securities Act or the Exchange Act, as the case may be, and the rules and regulations of the SEC promulgated thereunder applicable to such WorldQuest SEC Documents, and none of the WorldQuest SEC Documents contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The financial statements of WorldQuest included in the WorldQuest SEC Documents as of their respective dates comply as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto, have been prepared in accordance with generally accepted accounting principles (except, in the case of unaudited statements, as permitted by Form 10-Q of the SEC) applied on a consistent basis during the periods involved and fairly present in all material respects the consolidated financial position of WorldQuest and its consolidated subsidiaries as of the dates thereof and the consolidated results of their operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal and recurring year-end audit adjustments not material in amount). Except as reflected in the financial statements of WorldQuest included in the WorldQuest SEC Documents, neither WorldQuest nor any of its subsidiaries has any liabilities or obligations of any nature (whether accrued, absolute or contingent) which are required by generally accepted accounting principles to be set forth on a consolidated balance sheet of WorldQuest and its consolidated subsidiaries or in the notes thereto other than any liabilities and obligations incurred since September 30, 2003 in the ordinary course of business or which, individually or in the aggregate, would not have a WorldQuest Material Adverse Effect.

          (f) Information Supplied. None of the information supplied or to be supplied by WorldQuest or its subsidiaries or representatives in writing for inclusion or incorporation by reference in the WorldQuest Proxy Statement will, at the time it is filed with the SEC, first published, sent or given to shareholders or, at the time of the WorldQuest Stockholders Meeting, knowingly contain any untrue statement of a material fact or knowingly omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading. No representation or warranty is made by WorldQuest with respect to statements made or incorporated by reference therein based on information supplied by Ntera for inclusion or incorporation by reference therein.

          (g) Absence of Certain Changes or Events. Except for liabilities incurred in connection with or expressly permitted by this Agreement, since September, 2003, there has not been (i) any event, occurrence or development (other than those relating to the economy or

          (h) Litigation. Except as disclosed in the WorldQuest SEC Documents, there is no suit, action or proceeding pending or, to the knowledge of WorldQuest, threatened against or affecting WorldQuest or any of its subsidiaries that, individually or in the aggregate, would reasonably be expected to (i) have a WorldQuest Material Adverse Effect, (ii) impair the ability of WorldQuest to perform its obligations under this Agreement or (iii) prevent or materially delay the consummation of the transactions contemplated by this Agreement, nor is there any judgment, decree, injunction, rule or order of any Governmental Entity or arbitrator outstanding against WorldQuest or any of its subsidiaries having, or which is reasonably likely to have, any such effect.

          (i) Brokers. Except as disclosed in Schedule 3.2(i) of the WorldQuest Disclosure Schedule, no broker, investment banker, financial advisor or other person, is entitled to any broker’s, finder’s, financial advisor’s or other similar fee or commission in connection with the transactions contemplated by this Agreement based upon arrangements made by or on behalf of WorldQuest.

          (j) Pension and Benefit Plans; ERISA.

               (A) Section 3.2(j)(A) of the Worldquest Disclosure Letter contains a true and complete list of each “employee pension benefit plan” (as defined in Section 3(2) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”)) (hereinafter a “Worldquest Pension Plan"), “employee welfare benefit plan” (as defined in Section 3(l) of ERISA), stock option, stock purchase, restricted stock, phantom stock or other equity-based incentive plan, deferred compensation plan or arrangement, and other employee fringe benefit plan or arrangement maintained, contributed to or required to be maintained or contributed to by Worldquest or any other person or entity that together with Worldquest is treated as a single employer under Section 414(b), (c), (m) or (o) of the Code (each a “Worldquest Affiliate") for the benefit of any present or former officers, employees, directors or independent contractors of Worldquest or any Worldquest Affiliate (all the foregoing being herein referred collectively as “Worldquest Employee Benefit Plans"). Worldquest has made available to Ntera true, complete and correct copies of (1) each of the Worldquest Employee Benefit Plans and amendments thereto, (2) the three most recent annual reports on Form 5500 filed with the Internal Revenue Service with respect to each of the Worldquest Employee Benefit Plans (if any such report was required by applicable law), (3) the most recent summary plan description and any summaries of material modification for each of the Worldquest Employee Benefit Plans for which such a summary plan

24

description is required by applicable law and (4) each trust agreement and insurance or annuity contract relating to the Worldquest Employee Benefit Plans.

               (B) Each WorldQuest Employee Benefit Plan has been administered in all material respects in accordance with its terms. WorldQuest, WorldQuest Affiliates and all WorldQuest Employee Benefit Plans are in compliance with the applicable provisions of ERISA and the Code. Except as disclosed in Section 3.2(j)(B) of the WorldQuest Disclosure Letter, all reports, returns, notices and similar documents with respect to the WorldQuest Employee Benefit Plans required to be filed with any governmental agency or distributed to any WorldQuest Employee Benefit Plan participant have been duly, timely and accurately filed or distributed. Except as disclosed in Section 3.2(j)(B) of the WorldQuest Disclosure Letter, there are no investigations by any governmental agency, termination proceedings or other claims (except claims for benefits payable in the normal operation of WorldQuest Employee Benefit Plans), suits or proceedings against or involving any of the WorldQuest Employee Benefit Plans or asserting any rights or claims to benefits under any of the WorldQuest Employee Benefits Plans that could give rise to any liability, and there are not any facts to WorldQuest’s knowledge that could give rise to any material liability in the event of any such investigation, claim, suit or proceeding. No prohibited transactions (as defined in ERISA Section 406 or Code Section 4975) and no violations of ERISA Section 407 for which an applicable statutory or administrative exemption does not exist and for which WorldQuest or any WorldQuest Affiliate could be subject to any liability have occurred with respect to any WorldQuest Employee Benefit Plans.

               (C) Except as disclosed in Section 3.2(j)(C) of the Worldquest Disclosure Letter, none of the Worldquest Pension Plans are subject to Title IV of ERISA and none of Worldquest or any Worldquest Affilate has maintained or been required to contribute to a plan that is subject to Title IV of ERISA during the past six years.

               (D) Except as disclosed in Section 3.2(j)(D) of the WorldQuest Disclosure Letter, each WorldQuest Pension Plan intended to be qualified has been the subject of a determination letter from the Internal Revenue Service to the effect that such WorldQuest Pension Plan is qualified and exempt from Federal income taxes under Sections 401(a) and 501(a), respectively, of the Code; no such determination letter has been revoked, and, to the knowledge of WorldQuest, revocation has not been threatened; and such WorldQuest Pension Plan has not been amended since the effective date of its most recent determination letter in any respect that might adversely affect its qualification or materially increase its cost. WorldQuest has made available to Ntera a copy of the most recent determination letter received from the Internal Revenue Service with respect to each WorldQuest Pension Plan for which such a letter has been issued, as well as a copy of any pending application for a determination letter.

               (E) Except as disclosed on Section 3.2(j)(E) of the WorldQuest Disclosure Letter, no stock or other security issued by WorldQuest or any WorldQuest Affiliate forms or has formed a part of the assets of any of the WorldQuest Employee Benefit Plan or the WorldQuest Pension Plan.

25

               (F) Except as disclosed on Section 3.2(j)(F) of the WorldQuest Disclosure Letter, no payment that is owed or may become due to any director, officer, employee or agent of WorldQuest or a WorldQuest Affiliate will be non-deductible to WorldQuest or a WorldQuest Affiliate or be subject to the tax under section either Section 280G or 4999 of the Code.

               (G) With respect to each Worldquest Employee Benefit Plan that is not subject to United States law (a “Foreign Benefit Plan”): (i) all employer and employee contributions to each Foreign Benefit Plan required by law or by the terms of such Foreign Benefit Plan have been made, or, if applicable, accrued in accordance with normal accounting practices and a pro rata contribution for the period prior to and including the Effective Time has been made or accrued; (ii) the fair market value of the assets of each funded Foreign Benefit Plan, the liability of each insurer for any Foreign Benefit Plan funded through insurance or the book reserve established for any Foreign Benefit Plan, together with any accrued contributions, is sufficient to procure or provide for the benefits determined on any ongoing basis (actual or contingent) accrued to the Effective Time with respect to all current and former participants under such Foreign Benefit Plan according to the actuarial assumptions and valuations most recently used to determine employer contributions to such Foreign Benefit Plan, and none of the Transactions shall cause such assets or insurance obligations to be less than such benefit obligations; and (iii) each Foreign Benefit Plan required to be registered has been registered and has been maintained in good standing with applicable regulatory authorities. Each Foreign Benefit Plan is now and always has been operated in full compliance with all applicable non-United States laws.

               (H) No Worldquest Employee Benefit Plan provides, nor does Worldquest, or any Worldquest Affiliate have an obligation to provide, medical, life or other welfare benefits (whether or not insured) with respect to current or former employees after retirement or other termination of service, other than as required pursuant to Section 4980B of the Code.

          (k) Taxes. Except as would not reasonably be expected to have a WorldQuest Material Adverse Effect:

          (i) WorldQuest and each of its subsidiaries have timely filed all Tax Returns and in accordance in all material respects with all applicable laws. All such Tax Returns are correct and complete in all material respects. All taxes shown as due and payable on the Tax Returns have been paid and all other taxes of WorldQuest or any of its subsidiaries have been adequately reserved for in the financial statements included in the WorldQuest SEC Documents. There are no Liens on any of the assets of WorldQuest or any of its subsidiaries that arose in connection with any failure (or alleged failure) to timely pay any tax.

ARTICLE IX

Indemnification

          SECTION 9.1 Indemnity Obligations of Ntera and the Ntera Shareholders. Subject to the provisions of this Article IX, Ntera and the shareholders of Ntera hereby agree jointly and severally to indemnify and hold the Surviving Corporation (which for purposes of this Section shall include all directors, officers, employees, agents, affiliates and representatives of the Surviving Corporation) harmless from, and to reimburse the Surviving Corporation, for, any Indemnity Claim arising under the terms and conditions of this Agreement. For purposes of this Agreement, the term “Indemnity Claim” shall mean any loss, damage, deficiency, claim, liability, obligation, suit, action, fee, cost or expense of any nature whatsoever, including costs of investigation and settlement, incurred by the Surviving Corporation, resulting from:

          (a) any breach of any representation and warranty of Ntera or the Principal Shareholder which is contained in this Agreement;

          (b) any matter relating to, arising from or in connection with the Internal Revenue Service audit investigation of Radiant Telecom, Inc., which is more fully described on Section 3.1(j) of the Ntera Disclosure Schedule; or

47

          (c) the failure of any of Ntera’s subsidiaries to be at any time since their formation qualified subchapter S subsidiaries within the meaning of Section 1361(b)(3) of the Code.

          SECTION 9.2. Notification of Claims. Subject to the provisions of this Article IX, in the event of the occurrence of an event which the Surviving Corporation asserts constitutes an Indemnity Claim, the Surviving Corporation shall provide the Principal Shareholder, as the representative of the Ntera shareholders, with prompt notice of such event and shall otherwise make available to the Principal Shareholder all relevant information which is material to the claim, including information with respect to the availability of insurance coverage, and which is in the possession of the Indemnified Party. If such event involves the claim of any third party (a “Third Party Claim”), the Principal Shareholder shall have the right to elect to join in the defense, settlement, adjustment or compromise of any such Third Party Claim, and to employ counsel to assist the Surviving Corporation in connection with the handling of such claim, at the sole expense of the Principal Shareholder, and no such claim shall be settled, adjusted or compromised, or the defense thereof terminated, without the prior consent of the Principal Shareholder unless and until the Principal Shareholder shall have failed, after the lapse of a reasonable period of time, but in no event more than 30 days after written notice to it of the Third Party Claim, to join in the defense, settlement, adjustment or compromise of the same. Upon receipt of written notice of any Third Party Claim, the Surviving Corporation shall promptly, but in no event later than 15 days prior to the date a response or answer thereto is due (unless a response or answer is due within fewer than 15 days from the date the Surviving Corporation received notice thereof and then so long as reasonably possible prior to the due date thereof), inform the Principal Shareholder in writing thereof. The Surviving Corporation’s failure to give timely notice as provided above or to furnish the Principal Shareholder with any relevant data and documents in connection with any Third Party Claim shall not constitute a defense (in part or in whole) to any claim for indemnification by such party, except and only to the extent that such failure shall result in any material prejudice to the Ntera shareholders. The Principal Shareholder may elect, at his sole expense, to assume control of the defense, settlement, adjustment or compromise of any Third Party Claim, with counsel reasonably acceptable to the Surviving Corporation, insofar as such claim relates to the liability of the Ntera shareholders. In connection with any Third Party Claim, the Surviving Corporation, or the Principal Shareholder if he has assumed the defense of such claim pursuant to the preceding sentence, shall diligently pursue the defense of such Third Party Claim and the Surviving Corporation shall cooperate with the Principal Shareholder in connection with such claim, make available personnel, witnesses, books and records relevant thereto and grant such authorizations to the agents, representatives and counsel of the Surviving Corporation as the Principal Shareholder may request.

          SECTION 9.3. Survival. All representations and warranties contained in or made pursuant to this Agreement shall expire on the Final Determination Date. This Article IX shall survive the Closing and shall remain in effect (a) with respect to Sections 9.1(a) and (b), until the Final Determination Date, and (b) with respect to Section 9.1(c), indefinitely.

          SECTION 9.4 Limitations.

48

          (a) The Ntera shareholders shall not be required to indemnify the Surviving Corporation under Section 9.1 unless the aggregate of all amounts for which indemnity would otherwise be payable by the Ntera shareholders exceeds $100,000, and in such event, the Ntera shareholders shall be responsible for only such amount in excess of $100,000.

          (b) After the Closing, Section 9.1 hereof shall be the exclusive remedy for any breach of any representation and warranty contained in this Agreement, except for any breach resulting from the fraud of one of the Parties.

          (c) No Indemnity Claim shall include indirect, consequential, special or exemplary damages or any claim for a multiplier effect or any capitalization of out-of-pocket expenses or lost profits.

          SECTION 9.5. Satisfaction of Indemnity Obligations. Except as otherwise provided in this Section 9.5, the Surviving Corporation’s sole means for satisfying the indemnification obligations of Ntera and the Ntera shareholders shall be through the cancellation of Holdback Shares. In the event that the Ntera Shareholders are obligated to indemnify the Surviving Corporation pursuant to Section 9.1, the Surviving Corporation shall cancel and retire, without any further consideration therefor, a number of Holdback Shares equal to the quotient obtained by dividing (a) the total amount of the indemnification obligation of the Ntera shareholders calculated in accordance with this Article IX by (b) the average closing sale price on Nasdaq for a share of WorldQuest Common Stock over the ten trading days prior to the date on which the total amount of the indemnification obligation is determined. Any Holdback Shares cancelled and retired in accordance with this Section 9.5 shall affect the number of Holdback Shares of each Participating Stockholder on a pro rata basis. Notwithstanding the foregoing, the Surviving Corporation’s right to receive indemnification from the Ntera shareholders pursuant to Section 9.1(c) shall not be limited to the Holdback Shares. In the event that the Holdback Shares are not sufficient to cover any indemnifiable loss under Section 9.1(c) or in the event that the Holdback Shares have been released to the Participating Stockholders in accordance with Section 2.3, the Principal Shareholder, on behalf of the Ntera shareholders, shall fully indemnify the Surviving Corporation for such indemnifiable loss.

          NOW, THEREFORE, in consideration of the foregoing, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, the parties do hereby agree as follows:

Telecom and each of the Shareholders hereby grant to WorldQuest the following non-cancelable, irrevocable options: (i) an option to purchase the Shares (the “Telecom Purchase Option”) for a purchase price of $100,000 (the “Total Purchase Price”) in cash, payable pro rata among the Shareholders according to each such Shareholder’s percentage interest as set forth on Annex A hereto (the “Percentage Interests”), (ii) an option to purchase all right, title and interest in and to the assets used or held for use in connection with the Point-of-Sale Business (the “Point-of-Sale Assets”), free and clear of all liens and encumbrances (the “Asset Purchase Option”), for a purchase price of $50,000 (the “Asset Purchase Price”) in cash, payable to Telecom in exchange for the transfer, conveyance, assignment, sale and delivery of the Point-of-Sale Assets, and (iii) an option to purchase the Shares at any time during the Exercise Period (as defined in Section 2(a)) following the exercise by WorldQuest of, and the transfer of the Point-of- Sale Assets to WorldQuest pursuant to, the Asset Purchase Option (the “Share Purchase Option,”

F-4

               (d) Use commercially reasonable efforts to register or qualify the shares covered by such registration statement under such other securities or blue sky or other applicable laws of such jurisdictions within the United States as the Holders may reasonably request, to enable the Holders to consummate the public sale in such jurisdictions of the shares covered by the registration statement; provided, however, that the Company will not be required to (i) qualify generally to do business or subject itself to taxation in any jurisdiction where it would not otherwise be required to qualify or be subject but for this paragraph (d), or (ii) consent to general service of process in any such jurisdiction; and

who controls any of such Persons within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each, an “Holder Indemnitee”), against all claims, losses, damages and liabilities, or actions in respect thereof, arising out of or caused by any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement relating to the Registrable Securities or any related prospectus or arising out of or caused by 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 in the light of the circumstances in which they were made, and will reimburse the Holder Indemnitee for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action; provided, however, that the indemnity agreement contained in this paragraph (a) will not apply to amounts paid in settlement of any such claim, loss, damage, liability or action if such settlement is effected without the consent of the Company nor will the Company be liable in any such case to the extent that any such claim, loss, damage or liability arises out of or is caused by any untrue statement (or alleged untrue statement) or omission (or alleged omission) in any such document made in reliance on and in conformity with written information (including written negative responses to inquiries) furnished to the Company by or on behalf of such Holder Indemnitee for use in such registration statement or prospectus, and except that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such untrue statement (or alleged untrue statement) or omission (or alleged omission) made in the preliminary prospectus but eliminated or remedied in the amended prospectus on file with the SEC at the time the registration statement becomes effective or in any amendment or supplement thereto (the “Final Prospectus”), such indemnity agreement shall not inure to the benefit of any Holder Indemnitee, if a copy of the Final Prospectus was not furnished to the Person asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act.

               (b) Each Holder, severally but not jointly, shall indemnify the Company, each officer and director of the Company, the Company’s legal counsel and independent accountants, and each Person, if any, who controls any of such Persons within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each, a “Company Indemnitee”), against all claims, losses, damages and liabilities, or actions in respect thereof, arising out of or caused by any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement relating to the Registrable Securities or any related prospectus or arising out of or caused by 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 in the light of the circumstances in which they were made, and will reimburse each Company Indemnitee for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action; provided, however, that this paragraph (b) will apply only if (and only to the extent that) such untrue statement (or alleged untrue statement) or omission (or alleged omission) was made in reliance upon and in conformity with written information (including written negative responses to inquiries) furnished to the Company by or on behalf of such Holder Indemnitee for use in such registration or prospectus, and except that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such untrue statement (or alleged untrue statement) or omission (or alleged omission) made in the preliminary prospectus but eliminated or remedied in the amended prospectus on file with the SEC at the time the registration statement becomes effective or in the Final Prospectus, such indemnity agreement shall not inure to the benefit of

F-6

the Company Indemnitee, if a copy of the Final Prospectus was not furnished to the Person asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act; provided further that the indemnity agreement contained in this paragraph (b) will not apply to amounts paid in settlement of any such claim, loss, damage, liability or action if such settlement is effected without the consent of such Holder.

               (c) Each Holder Indemnitee or Company Indemnitee (the “indemnified party”) will give notice to the party required to provide indemnification hereunder (the “indemnifying party”) promptly after such indemnified party has actual knowledge of any claim as to which indemnity may be sought, and will permit the indemnifying party (at its expense) to assume the defense of any claim or any litigation resulting therefrom; provided, however, that counsel for the indemnifying party, who will conduct the defense of such claim or litigation, will be reasonably satisfactory to the indemnified party, and the indemnified party may participate in such defense at such party’s expense; provided further that the omission by any indemnified party to give notice as provided herein will not relieve the indemnifying party of its obligations under this Section 2.6 except to the extent that the omission is materially prejudicial to the ability of the indemnifying party to defend. No indemnifying party, in the defense of any such claim or litigation, will, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement which 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.

               (d) If the indemnification provided for in this Section 2.6 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage or expense referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, will contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage or expense, in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions which resulted in such loss, liability, claim, damage or expense, as well as any other relevant equitable considerations.

          2.7 Effect of Lock-Up Agreements. Notwithstanding anything to the contrary contained herein, (a) the Registration of Registrable Securities in accordance with this Agreement shall not limit or otherwise remove the restrictions on the transferability of any Holder’s Common Shares under the Lock-Up Agreements and (b) no Registrable Securities shall be transferable until such time as the restrictions on transferability with respect to such Registrable Securities, if any, shall lapse in accordance with the terms and conditions of the Lock-Up Agreements.

ARTICLE III

Termination

          3.1 Termination. This Agreement shall terminate with respect to each Holder and be of no further force and effect on the earlier of (i) the date on which the Shelf Registration Statement filed by the Company pursuant to a Registration ceases to be effective in accordance

F-7

with the terms of this Agreement, (ii) the first date on which there are no Registrable Securities subject to this Agreement held by such Holder or (iii) upon the first day on which all of the Holder’s Registrable Securities may be sold, within a 90-day period, without registration under the Securities Act, pursuant to Rule 144.

ARTICLE IV

Miscellaneous

          4.1 Recapitalization, Exchanges, etc. Affecting the Common Shares. The provisions of this Agreement shall apply to the full extent set forth herein with respect to (a) the Registrable Securities and (b) any and all shares of the Company or any successor or assign of the Company (whether by merger, consolidation, sale of assets or otherwise) which may be issued in respect of, in exchange for, or in substitution for the Registrable Securities, by reason of any dividend, split, reverse split, combination, recapitalization, reclassification, merger, consolidation or otherwise. In the event of any change in the capitalization of the Company as a result of any capital split, dividend or combination, the provisions of this Agreement shall be appropriately adjusted.

          4.2 Specific Performance; Jurisdiction for Service of Process. Each of the parties hereto acknowledges and agrees that any breach of the agreements and covenants contained in this Agreement would cause irreparable injury to the other parties for which such parties would have no adequate remedy at law. In addition to any other remedy for which a Person may be entitled, each of the parties hereto agrees that temporary and permanent injunctive and other equitable relief and specific performance may be granted without proof of actual damages or inadequacy of legal remedy in any proceeding that may be brought to enforce any of the provisions of this Agreement. Each of the parties hereto irrevocably consents to the jurisdiction of the courts of the State of Delaware and of any federal court located in such state in connection with any action or proceeding arising out of or relating to this Agreement or a breach of this Agreement. Each party hereby waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of venue of any action or proceeding arising out of or relating to this Agreement brought in the State of Delaware, and further irrevocably waives, to the fullest extent permitted by law, any claim that any such action or proceeding brought in such state has been brought in an inconvenient forum.

          4.3 Expenses. Except as otherwise expressly provided herein, all costs and expenses incurred in connection with this Agreement shall be paid by the party incurring such costs and expenses.

          4.4 Successors and Assigns. All the terms and provisions of this Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable by the respective successors, heirs, executors, administrators, legal representatives and permitted assigns of the parties hereto. No party hereto shall assign this Agreement or any part hereof or any benefit or interest herein without the prior written consent of the other parties hereto, except that a Holder may assign its rights under this Agreement in connection with any transfer of any Registrable Securities either during his or her lifetime, or on death by will or intestacy, to his or her immediate family or to a trust or family limited partnership, the beneficiaries of which are

F-8

exclusively the undersigned and/or members of his or her immediate family; provided, however, that prior to any such assignment and transfer, each such transferee shall execute an agreement, satisfactory in form and substance to the Company, pursuant to which each such transferee shall agree to be bound by the provisions of this Agreement. For the purposes of this paragraph, “immediate family” shall mean spouse, lineal descendant, father, mother, brother or sister of the transferor.

          4.5 Survival. The respective indemnities, agreements, representations, warranties and each other provision set forth in this Agreement or made pursuant hereto shall remain in full force and effect regardless of any investigation (or statements as to the results thereto) made by or on behalf of the Holders of Registrable Securities, any director, officer or partner of such Holder, any agent or underwriter or any director, officer or partner thereof, or any controlling Person of any of the foregoing, and shall survive delivery of and payment for the Registrable Securities to the Holders and the transfer of Registrable Securities by the Holders.

          4.6 Amendment; Waiver.

               (a) This Agreement may be amended only by a written instrument signed by the Company and a majority of the Holders with Registrable Securities then outstanding and subject to this Agreement. This Agreement may not be amended by oral agreement, even if supported by new consideration.

               (b) No provision of this Agreement may be waived orally, but only by a written instrument signed by the party against whom enforcement of such waiver is sought. No failure or delay on the part of the Company or any Holder in exercising any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. No course of dealing between the Company and the Holder nor any delay in exercising any rights hereunder shall operate as a waiver of any rights of the Company or the Holder. The Holder shall be bound from and after the date of the receipt of a written notice from the Company setting forth such amendment or waiver, whether or not the Registrable Securities shall have been marked to indicate such amendment or waiver.

          4.7 Notices. Except as otherwise provided in this Agreement, notices and other communications under this Agreement shall be in writing (including a writing delivered by facsimile transmission) and shall be deemed to have been duly given if delivered personally, or sent by either certified or registered mail, return receipt requested, postage prepaid, or by overnight courier guaranteeing next day delivery, or by telex or facsimile, at the following addresses:

F-9

Each party may, by written notice given to the Company in accordance with this Section 4.7, change the address to which such notice or other communications are to be sent to it. All such notices and communications shall be deemed to have been given on the date of delivery thereof, if delivered by hand, on the fifth day after the mailing thereof, if mailed, on the next day after the sending thereof, if by overnight courier and when receipt is acknowledged, if telecopied.

          4.8 APPLICABLE LAW. THIS AGREEMENT SHALL BE DEEMED TO BE A CONTRACT MADE UNDER THE LAWS OF THE STATE OF DELAWARE AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, AND THE RIGHTS OF THE PARTIES SHALL BE GOVERNED BY THE LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO THE CONFLICTS OF LAW PRINCIPLES THEREOF.

          4.9 Headings. Article, section and paragraph headings are inserted for convenience only and do not constitute a part of this Agreement. Unless the context requires otherwise: (i) the gender (or lack of gender) of all words used in this Agreement includes the masculine, feminine and neuter; (ii) references to Articles and Sections (other than in connection with the Securities Act or the Exchange Act) refer to Articles and Sections of this Agreement; (iii) all references to days or months shall be deemed references to calendar days or months; (iv) the words “hereof,” “herein” or “hereunder” or words of similar import referring to this Agreement refer to this Agreement as a whole and not to any particular provision of this Agreement; (v) unless otherwise specifically provided for herein, the term “or” shall not be deemed to be exclusive; and (vi) the words “include,” “includes” or “including” shall be deemed to be followed by the words “without limitation.”

          4.10 Definition of Beneficial Ownership. For purposes of this Agreement, a Person shall be deemed to be a “beneficial owner” of any Registrable Securities of the Company (i) which such Person or any of its Affiliates beneficially owns, directly or indirectly; or (ii) which such Person or any of its Affiliates has, directly or indirectly, (a) the right or obligation to acquire (whether such right or obligation is exercisable immediately or only after the passage of time or the occurrence of an event), pursuant to any agreement or arrangement or upon the exercise of conversion rights, exchange rights, warrants or options, or otherwise, or (b) the right to vote or dispose of, including pursuant to any agreement or arrangement; (iii) which is beneficially owned, directly or indirectly, by any other Person (or any Affiliate thereof) with which such Person or any of its Affiliates has any agreement or arrangement for the purpose of acquiring, holding, voting or disposing of such Registrable Securities; or (iv) of which such Person would be considered the beneficial owner pursuant to Rule 13d-3 (or any successor thereto) under the Exchange Act.

          4.11 Severability. If any provision of this Agreement, or the application of any such provision to any Person or circumstance, shall be declared judicially to be invalid, unenforceable or void, such decision shall not have the effect of invalidating or voiding the

F-10

remainder of this Agreement, it being the intent and agreement of the parties that this Agreement shall be deemed amended by modifying such provision to the extent necessary to render it valid, legal and enforceable while preserving its intent or, if such modification is not possible, by substituting therefor another provision that is legal and enforceable and that achieves the same objective.

          4.12 Integration. This Agreement and the documents referred to herein or delivered pursuant hereto which form a part hereof contain the entire understanding of the parties with respect to the subject matter hereof. There are no restrictions, agreements, promises, representations, warranties, covenants or undertakings with respect to the subject matter hereof other than those expressly set forth or referred to herein. This Agreement supersedes all prior agreements and understandings between the parties with respect to this subject matter.

          4.13 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which shall constitute one and the same instrument, and it shall not be necessary in making proof of this Agreement to produce or account for more than one such counterpart.
