(b) Committee Authority. The Committee shall have the sole authority to (i) determine the Employees, Consultants and Non-Employee Directors to whom Grants shall be made under the Plan; (ii) determine the type, size and terms of the Grants to be made to each Participant; (iii) determine the time when the Grants will be made and the duration of any applicable exercise or restriction period, including the criteria for exercisability and the acceleration of exercisability and vesting; (iv) amend the terms of any previously issued Grant, subject to the provisions of Section 19; (v) adopt guidelines separate from the Plan that set forth the specific terms and conditions for Grants under the Plan; and (vi) deal with any other matters arising under the Plan. However, the Board may ratify or approve any Grants as it deems appropriate and has the authority to administer the Plan. To the extent that the Board makes Grants and administers the Plan, references in the Plan to the “Committee” shall be deemed to refer to the Board.

(c) Committee Determinations. The Committee shall have full power and express discretionary authority to administer and interpret the Plan, to make factual determinations and to adopt or amend such rules, regulations, agreements and instruments for implementing the Plan and for the conduct of its business as it deems necessary or advisable, in its sole discretion. The Committee’s interpretations of the Plan and all determinations made by the Committee pursuant to the powers vested in it hereunder shall be conclusive and binding on all persons having any interest in the Plan or in any Grants awarded hereunder. All powers of the Committee shall be executed in its sole discretion, in the best interest of Verticalnet, not as a fiduciary, and in keeping with the objectives of the Plan and need not be uniform as to similarly situated individuals.

Section 4. Grants

Grants under the Plan may consist of Options, SARs, Stock Units, Performance Shares, Stock Awards and Other Stock-Based Awards. All Grants shall be subject to the terms and conditions set forth herein and to such other terms and conditions consistent with the Plan as the Committee deems appropriate and as are specified in writing by the Committee in separate guidelines or to the individual in the Grant Letter or an amendment to the guidelines or Grant Letter. The Committee shall approve the form and provisions of each Grant Letter. Grants under a particular Section of the Plan need not be uniform as among the Participants. All Grants shall be made

conditional upon the Participant’s acknowledgement, in writing or by acceptance of the Grant, that all decisions and determinations of the Committee shall be final and binding on the Participant, his or her beneficiaries, and any other person having or claiming an interest under such Grant.

Section 5. Shares of Stock Subject to the Plan

(a) Shares Authorized. Subject to adjustment as described below, the aggregate number of shares of Stock that may be issued or transferred under the Plan is 4,000,000 shares. The Shares may be authorized, but unissued, shares of Stock or reacquired shares of Stock, including shares purchased by Verticalnet on the open market for purposes of the Plan. Grants paid in cash shall not count against the foregoing share limits.

(b) Share Counting. For administrative purposes, when the Committee makes a Grant payable in Stock, the Committee shall reserve shares of Stock equal to the maximum number of shares of Stock that may be payable under the Grant. If and to the extent Options or SARs granted under the Plan terminate, expire, or are canceled, forfeited, exchanged or surrendered without having been exercised or if any Stock Awards, Stock Units, Performance Shares or Other Stock-Based Awards are forfeited or terminated, or otherwise not paid in full, the shares subject to such Grants which have not been issued shall again be available for purposes of the Plan. To the extent any Grants are paid in cash, and not in shares of Stock, any shares previously reserved for issuance or transfer pursuant to such Grants shall again be available for issuance or transfer under the Plan.

(c) Individual Limits. All Grants under the Plan shall be expressed in shares of Stock. The maximum aggregate number of shares of Stock with respect to which all Grants may be made under the Plan to any individual during any calendar year shall be 500,000 shares, subject to adjustment as described below. The individual limit described in this subsection (c) shall apply without regard to whether the Grants are to be paid in Stock or in cash. All cash payments shall equal the Fair Market Value of the shares of Stock to which the cash payment relates.

(d) Adjustments. If there is any change in the number or kind of shares of Stock outstanding (i) by reason of a stock dividend, spinoff, recapitalization, stock split, or combination or exchange of shares; (ii) by reason of a merger, reorganization or consolidation; (iii) by reason of a reclassification or change in par value; or (iv) by reason of any other extraordinary or unusual event affecting the outstanding Stock as a class without Verticalnet’s receipt of consideration, or if the value of outstanding shares of Stock is substantially reduced as a result of a spinoff or Verticalnet’s payment of an extraordinary dividend or distribution, the maximum number of shares of Stock available for issuance under the Plan, the maximum number of shares of Stock for which any individual may receive pursuant to Grants in any year, the number of shares covered by outstanding Grants, the kind of shares to be issued or transferred under the Plan, and the price per share or the applicable market value of such Grants shall be appropriately adjusted by the Committee to reflect any increase or decrease in the number of, or change in the kind or value of, issued shares of Stock to preclude, to the extent practicable, the enlargement or dilution of rights and benefits under such Grants; provided, however, that any fractional shares resulting from such adjustment shall be eliminated. Any adjustments determined by the Committee shall be final, binding and conclusive.

Section 6. Eligibility for Participation

(a) Eligible Persons. All Employees, including Employees who are officers or members of the Board, and all Non-Employee Directors shall be eligible to participate in the Plan. Consultants are eligible to participate in the Plan if they perform bona fide services for the Company, the services are not in connection with the offer or sale of securities in a capital-raising transaction, and the Consultants do not directly or indirectly promote or maintain a market for Verticalnet’s securities.

(b) Selection of Participants. The Committee shall select the Employees, Consultants and Non-Employee Directors to receive Grants and shall determine the terms and conditions of the Grant and the number of shares of Stock subject to each Grant.

Section 7. Options

(a) General Requirements. The Committee may grant Options to any Employee, Consultant or Non-Employee Director upon such terms and conditions as the Committee deems appropriate under this Section 7.

(b) Number of Shares. The Committee shall determine the number of shares of Stock that will be subject to each Grant of Options to Employees, Consultants and Non-Employee Directors.

(c) Type of Option and Price.

(i) The Committee may grant Incentive Stock Options or Nonqualified Stock Options or any combination of Incentive Stock Options and Nonqualified Stock Options. Incentive Stock Options may be granted only to Employees of Verticalnet or its Parent or Subsidiaries. Nonqualified Stock Options may be granted to Employees, Consultants and Non-Employee Directors.

(ii) The Option Price shall be determined by the Committee and may be equal to or greater than the Fair Market Value of the shares of Stock subject to the Grant on the Date of Grant; provided, however, that an Incentive Stock Option may not be granted to an Employee who, at the Date of Grant, owns stock possessing more than 10% of the total combined voting power of all classes of stock of Verticalnet or any Parent or Subsidiary, unless the Option Price is not less than 110% of the Fair Market Value on the Date of Grant.

(d) Option Term. The Committee shall determine the term of each Option. The term of an Option shall not exceed ten years from the Date of Grant. However, an Incentive Stock Option that is granted to an Employee who, at the Date of Grant, owns stock possessing more than 10% of the total combined voting power of all classes of stock of Verticalnet, or any Parent or Subsidiary, may not have a term that exceeds five years from the Date of Grant.

(e) Exercisability of Options. Options shall become exercisable in accordance with such terms and conditions as may be determined by the Committee and specified in the Grant Letter. The Committee may accelerate the exercisability of any or all outstanding Options at any time for any reason.

(f) Termination of Employment or Service. Except as provided in the Grant Letter, an Option may only be exercised while the Participant is employed by, or providing service to, the Company. The Committee shall specify in the Grant Letter under what circumstances and during what time periods a Participant may exercise an Option after termination of employment or service.

(g) Exercise of Options. A Participant may exercise an Option that has become exercisable, in whole or in part, by delivering a notice of exercise to Verticalnet or its designated agent. The Participant shall pay the Option Price and any withholding taxes for the Option (i) in cash or by certified or cashier’s check; (ii) with the approval of the Committee, by delivering shares of Stock owned by the Participant and having a Fair Market Value on the date of exercise equal to the Option Price or by attestation (on a form prescribed by the Committee) to ownership of shares of Stock having an aggregate Fair Market Value on the date of exercise equal to the Option Price; (iii) in cash, on the T+3 settlement date that occurs after the exercise date specified in the notice of exercise, provided that the Participant exercises the Option through an irrevocable agreement with a registered broker and the payment is made in accordance with procedures permitted by Regulation T of the Federal Reserve Board and such procedures do not violate applicable law; or (iv) by such other method as the Committee may approve, to the extent permitted by applicable law. Shares of Stock used to exercise an Option pursuant to subsection (ii) shall have been held by the Participant for the requisite period of time to avoid adverse accounting consequences to Verticalnet with respect to the Option. Payment for the shares pursuant to the Option, and any required withholding taxes, must be received by the time specified by the Committee depending on the type of payment being made.

(h) Limits on Incentive Stock Options. Each Incentive Stock Option shall provide that if the aggregate Fair Market Value on the Date of Grant with respect to which Incentive Stock Options are exercisable for the first

time by a Participant during any calendar year, under the Plan or any other stock option plan of Verticalnet or a Parent or Subsidiary, exceeds $100,000, then the Option, as to the excess, shall be treated as a Nonqualified Stock Option.

Section 8. SARs

(a) General Requirements. The Committee may grant SARs to any Employee, Consultant or Non-Employee Director, upon such terms and conditions as the Committee deems appropriate under this Section 8. Each SAR shall represent the right of the Participant to receive, upon settlement of the SAR, shares of Stock or cash equal to the amount by which the Fair Market Value of a share of Stock on the date of exercise of the SAR exceeds the base amount of the SAR as described below in Section 8(c).

(b) Terms of SARs. The Committee shall determine the terms and conditions of SARs and may grant SARs separately from or in tandem with any Option (for all or a portion of the applicable Option). Tandem SARs may be granted either at the time the Option is granted or any time thereafter while the Option remains outstanding; provided, however, that in the case of an Incentive Stock Option, SARs may be granted only at the time of the grant of the Incentive Stock Option. The Committee will determine the number of SARs to be granted, the base amount, the vesting and other restrictions applicable to SARs and the period during which SARs will remain exercisable.

(c) Base Amount. The Committee shall establish the base amount of the SAR at the time the SAR is granted; provided, however, that the base amount shall not be less than the Fair Market Value of a share of Stock on the Date of Grant.

(d) Payment With Respect to SARs. The Committee shall determine whether the appreciation in an SAR shall be paid in the form of cash, in Stock, or in a combination of the two, in such proportion as the Committee deems appropriate. For purposes of calculating the number of shares of Stock to be received, Stock shall be valued at its Fair Market Value on the date of exercise of the SAR. If shares of Stock are to be received upon exercise of an SAR, cash shall be delivered in lieu of any fractional share.

(e) Requirement of Employment or Service. The Committee shall determine in the Grant Letter under what circumstances a Participant may retain SARs after termination of the Participant’s employment or service, and the circumstances under which SARs may be forfeited.

Section 9. Stock Units

(a) General Requirements. The Committee may grant Stock Units to any Employee, Consultant or Non-Employee Director, upon such terms and conditions as the Committee deems appropriate under this Section 9. Each Stock Unit shall represent the right of the Participant to receive a share of Stock or an amount based on the value of a share of Stock. All Stock Units shall be credited to accounts on Verticalnet’s records for purposes of the Plan.

(b) Terms of Stock Units. The Committee may grant Stock Units that are payable if specified performance goals or other conditions are met, or under other circumstances. Stock Units may be paid at the end of a specified period, or payment may be deferred to a date authorized by the Committee. The Committee shall determine the number of Stock Units to be granted and the requirements applicable to such Stock Units.

(c) Payment With Respect to Stock Units. Payment with respect to Stock Units shall be made in cash, in Stock, or in a combination of the two, as determined by the Committee. The Grant Letter shall specify the maximum number of shares that shall be paid under the Stock Units.

(d) Requirement of Employment or Service. The Committee shall determine in the Grant Letter under what circumstances a Participant may retain Stock Units after termination of the Participant’s employment or service, and the circumstances under which Stock Units may be forfeited.

Section 10. Performance Shares

(a) General Requirements. The Committee may grant Performance Shares to an Employee, Consultant or Non-Employee Director, upon such terms and conditions as the Committee deems appropriate under this Section 10. Each Performance Share shall represent the right of the Participant to receive a share of Stock or an amount based on the value of a share of Stock, if specified performance goals are met. All Performance Shares shall be credited to accounts on Verticalnet’s records for purposes of the Plan.

(b) Terms of Performance Shares. The Committee shall establish the performance goals and other conditions for payment of Performance Shares. Performance Shares may be paid at the end of a specified performance or other period, or payment may be deferred to a date authorized by the Committee. The Committee shall determine the number of Performance Shares to be granted and the requirements applicable to such Performance Shares.

(c) Payment With Respect to Performance Shares. Payment with respect to Performance Shares shall be made in cash, in Stock, or in a combination of the two, as determined by the Committee. The Committee shall establish in the Grant Letter a target amount to be paid under a Performance Share based on achievement of the performance goals.

(d) Requirement of Employment or Service. The Committee shall determine in the Grant Letter under what circumstances a Participant may retain Performance Shares after termination of the Participant’s employment or service, and the circumstances under which Performance Shares may be forfeited.

Section 11. Stock Awards

(a) General Requirements. The Committee may issue or transfer shares of Stock to an Employee, Consultant or Non-Employee Director under a Stock Award, upon such terms and conditions as the Committee deems appropriate under this Section 11. Shares of Stock issued or transferred pursuant to Stock Awards may be issued or transferred for cash consideration or for no cash consideration, and subject to restrictions or no restrictions, as determined by the Committee. The Committee may establish conditions under which restrictions on Stock Awards shall lapse over a period of time or according to such other criteria as the Committee deems appropriate, including restrictions based upon the achievement of specific performance goals.

(b) Number of Shares. The Committee shall determine the number of shares of Stock to be issued or transferred pursuant to a Stock Award and any restrictions applicable to such shares.

(c) Requirement of Employment or Service. The Committee shall determine in the Grant Letter under what circumstances a Participant may retain Stock Awards after termination of the Participant’s employment or service, and the circumstances under which Stock Awards may be forfeited.

(d) Restrictions on Transfer. While Stock Awards are subject to restrictions, a Participant may not sell, assign, transfer, pledge or otherwise dispose of the shares of a Stock Award except upon death as described in Section 16. Each certificate, or electronic book entry equivalent, for a share of a Stock Award shall contain a legend giving appropriate notice of the restrictions in the Grant. The Participant shall be entitled to have the legend removed when all restrictions on such shares have lapsed. The Committee may retain possession of any stock certificates for Stock Awards until all restrictions on such shares have lapsed.

(e) Right to Vote and to Receive Dividends. Unless the Committee determines otherwise, the Participant shall have the right to vote shares subject to Stock Awards and to receive any dividends or other distributions paid on such shares during the restriction period. The Committee may determine that a Participant’s entitlement to dividends or other distributions with respect to a Stock Award shall be subject to achievement of performance goals or other conditions.

Section 12. Other Stock-Based Awards

The Committee may grant other awards that are cash-based or based on, measured by or payable in Stock to Employees, Consultants or Non-Employee Directors, on such terms and conditions as the Committee deems appropriate under this Section 12. Other Stock-Based Awards may be granted subject to achievement of performance goals or other conditions and may be payable in Stock or cash, or in a combination of the two, as determined by the Committee in the Grant Letter.

Section 13. Qualified Performance-Based Compensation

(a) Designation as Qualified Performance-Based Compensation. The Committee may determine that Stock Units, Performance Shares, Stock Awards or Other Stock-Based Awards granted to an Employee shall be considered “qualified performance-based compensation” under section 162(m) of the Code. The provisions of this Section 13 shall apply to any such Grants that are to be considered “qualified performance-based compensation” under section 162(m) of the Code. To the extent that Grants of Stock Units, Performance Shares, Stock Awards or Other Stock-Based Awards designated as “qualified performance-based compensation” under section 162(m) of the Code are made, no such Grant may be made as an alternative to another Grant that is not designated as “qualified performance based compensation” but instead must be separate and apart from all other Grants made.

(b) Performance Goals. When Stock Units, Performance Shares, Stock Awards or Other Stock-Based Awards that are to be considered “qualified performance-based compensation” are granted, the Committee shall establish in writing (i) the objective performance goals that must be met; (ii) the period during which performance will be measured; (iii) the maximum amounts that may be paid if the performance goals are met; and (iv) any other conditions that the Committee deems appropriate and consistent with the Plan and the requirements of section 162(m) of the Code for “qualified performance-based compensation.” The performance goals shall satisfy the requirements for “qualified performance-based compensation,” including the requirement that the achievement of the goals be substantially uncertain at the time they are established and that the performance goals be established in such a way that a third party with knowledge of the relevant facts could determine whether and to what extent the performance goals have been met. The Committee shall not have discretion to increase the amount of compensation that is payable upon achievement of the designated performance goals, but the Committee may reduce the amount of compensation that is payable upon achievement of the designated performance goals.

(c) Criteria Used for Objective Performance Goals. The Committee shall use objectively determinable performance goals based on one or more of the following criteria: Stock price, earnings per share of Stock, net earnings, operating earnings, return on assets, shareholder return, return on equity, growth in assets, unit volume, sales, market share, or strategic business criteria consisting of one or more objectives based on meeting specific revenue goals, market penetration goals, geographic business expansion goals, cost goals, or goals relating to acquisitions or divestitures. The performance goals may relate to the Participant’s business unit or the performance of Verticalnet, a Subsidiary, or Verticalnet and its Subsidiaries as a whole, or any combination of the foregoing. Performance goals need not be uniform as among Participants.

(d) Timing of Establishment of Goals. The Committee shall establish the performance goals in writing either before the beginning of the performance period or during a period ending no later than the earlier of (i) 90 days after the beginning of the performance period or (ii) the date on which 25% of the performance period has been completed, or such other date as may be required or permitted under applicable regulations under section 162(m) of the Code.

(e) Certification of Results. The Committee shall certify and announce the results for the performance period to all Participants after Verticalnet announces Verticalnet’s financial results for the performance period. The Committee shall determine the amount, if any, to be paid pursuant to each Grant based on the achievement of the performance goals and the terms of each Grant Letter.

(f) Death, Disability or Other Circumstances. The Committee may provide in the Grant Letter that Grants shall be payable, in whole or in part, in the event of the Participant’s death or disability, a Change in Control or under other circumstances consistent with the Treasury regulations and rulings under section 162(m) of the Code.

Section 14. Deferrals

The Committee may permit or require a Participant to defer receipt of the payment of cash or the delivery of shares of Stock that would otherwise be due to the Participant in connection with any Grant. The Committee shall establish rules and procedures for such deferrals, which shall be consistent with the requirements of section 409A of the Code and the corresponding Treasury regulations and rulings.

Section 15. Withholding of Taxes

(a) Required Withholding. All Grants under the Plan shall be subject to applicable federal (including FICA), state and local tax withholding requirements. Verticalnet may (i) require that the Participant or other person receiving or exercising Grants pay to the Company the amount of any federal, state or local taxes that the Company is required to withhold with respect to such Grants, or (ii) deduct from other wages paid by the Company the amount of any withholding taxes due with respect to such Grants.

(b) Election to Withhold Shares. If the Committee so permits, a Participant may elect to satisfy the Company’s tax withholding obligation with respect to Grants paid in Stock by having shares withheld, at the time such Grants become taxable, up to an amount that does not exceed the minimum applicable withholding tax rate for federal (including FICA), state and local tax liabilities. The elections described in this subsection (b) must be in a form and manner prescribed by the Committee and may be subject to the prior approval of the Committee.

Section 16. Transferability of Grants

(a) In General. Except as provided in this Section 16, only the Participant may exercise rights under a Grant during the Participant’s lifetime. A Participant may not transfer those rights except by will or by the laws of descent and distribution, or, with respect to Grants other than Incentive Stock Options, if permitted in any specific case by the Committee, pursuant to a domestic relations order. When a Participant dies, the Successor Participant may exercise such rights in accordance with the terms of the Plan. A Successor Participant must furnish proof satisfactory to Verticalnet of his or her right to receive the Grant under the Participant’s will or under the applicable laws of descent and distribution.

(b) Transfer of Nonqualified Stock Options. Notwithstanding the foregoing, the Committee may provide in a Grant Letter that a Participant may transfer Nonqualified Stock Options to family members or other persons or entities, consistent with applicable securities laws, according to such terms as the Committee may determine; provided that the Participant receives no consideration for the transfer of a Nonqualified Stock Option and the transferred Nonqualified Stock Option shall continue to be subject to the same terms and conditions as were applicable to the Nonqualified Stock Option immediately before the transfer.

Section 17. Consequences of a Change in Control

(a) Assumption of Grants. Upon a Change in Control where Verticalnet is not the surviving corporation (or survives only as a subsidiary of another corporation), unless the Committee determines otherwise, all outstanding Options and SARs that are not exercised shall be assumed by, or replaced with comparable options and rights by, the surviving corporation (or a parent or subsidiary of the surviving corporation), and other Grants that remain outstanding shall be converted to similar grants of the surviving corporation (or a parent or subsidiary of the surviving corporation).

(b) Other Alternatives. Notwithstanding the foregoing, in the event of a Change in Control, the Committee may take any of the following actions with respect to any or all outstanding Grants, without the consent of any Participant: (i) determine that outstanding Options and SARs shall accelerate and become exercisable, in whole

or in part; (ii) determine that the restrictions and conditions on outstanding Stock Awards shall lapse, in whole or in part; (iii) provide that Participants holding outstanding Performance Shares shall receive payment, in whole or in part, in settlement of such Performance Shares, in an amount determined by the Committee, based on the Participant’s target payment for the performance period and the portion of the performance period that precedes the Change in Control; (iv) determine that outstanding Stock Units shall become payable, in whole or in part, in cash, Stock or other property in an amount not less than their target amount, as determined by the Committee; (v) provide that Other Stock-Based Awards shall become fully payable, in whole or in part, in cash, Stock or other property, in amounts determined by the Committee; (vi) the Committee may require that Participants surrender their outstanding Options and SARs in exchange for a payment by Verticalnet, in cash, Stock or other property, as determined by the Committee, in an amount equal to the amount by which the then Fair Market Value subject to the Participant’s unexercised Options and SARs exceeds the Option Price of the Options or the base amount of the SARs, as applicable; (vii) after giving Participants an opportunity to exercise their outstanding Options and SARs, the Committee may terminate any or all unexercised Options and SARs at such time as the Committee deems appropriate; and/or (viii) with respect to Participants holding Stock Units, Performance Shares or Other Stock-Based Awards, the Committee may determine that such Participants shall receive a payment in settlement of such Stock Units, Performance Shares or Other Stock-Based Awards, in such amount and form as may be determined by the Committee. Such acceleration, surrender, termination or settlement shall take place as of the date of the Change in Control or such other date as the Committee may specify.

Section 18. Requirements for Issuance of Shares

No shares of Stock shall be issued or transferred in connection with any Grant hereunder unless and until all legal requirements applicable to the issuance of such shares have been complied with to the satisfaction of the Committee. The Committee shall have the right to condition any Grant made to any Participant hereunder on such Participant’s undertaking in writing to comply with such restrictions on his or her subsequent disposition of such shares of Stock as the Committee shall deem necessary or advisable, and certificates representing such shares may be legended to reflect any such restrictions. Certificates representing shares of Stock issued or transferred under the Plan will be subject to such stop-transfer orders and other restrictions as may be required by applicable laws, regulations and interpretations, including any requirement that a legend be placed thereon.

Section 19. Amendment and Termination of the Plan

(a) Amendment. The Board may amend or terminate the Plan at any time; provided, however, that the Board shall not amend the Plan without approval of the shareholders of Verticalnet if such approval is required in order to comply with the Code or applicable laws, or to comply with applicable stock exchange requirements. No amendment or termination of this Plan shall, without the consent of the Participant, impair any rights or obligations under any Grant previously made to the Participant, unless such right has been reserved in the Plan or the Grant Letter, or except as provided in Section 20(b) below.

(b) No Repricing Without Shareholder Approval. Notwithstanding anything in the Plan to the contrary, without the prior approval of Verticalnet’s shareholders, no Grant under the Plan may be repriced, replaced, regranted through cancellation or modified if the effect would be to reduce the exercise price for the shares underlying such Grant; provided, however, that the foregoing shall not apply to any adjustment made to a Grant pursuant to Section 5(d) of the Plan. In addition, without the prior approval of Verticalnet’s shareholders, the Committee may not cancel an outstanding Grant that is underwater for the purpose of granting a replacement Grant of a different type.

(c) Shareholder Approval for “Qualified Performance-Based Compensation.” If Stock Units, Performance Shares, Stock Awards or Other Stock-Based Awards are granted as “qualified performance-based compensation” under Section 13 above, the Plan must be reapproved by Verticalnet’s shareholders no later than the first shareholders meeting that occurs in the fifth year following the year in which the shareholders previously approved the provisions of Section 13, if additional Grants are to be made under Section 13 and if required by section 162(m) of the Code or the regulations thereunder.

(d) Termination of Plan. The Plan shall terminate on the day immediately preceding the tenth anniversary of its Effective Date, unless the Plan is terminated earlier by the Board or is extended by the Board with the approval of the shareholders. The termination of the Plan shall not impair the power and authority of the Committee with respect to an outstanding Grant.

Section 20. Miscellaneous

(a) Grants in Connection with Corporate Transactions and Otherwise. Nothing contained in this Plan shall be construed to (i) limit the right of the Committee to make Grants under this Plan in connection with the acquisition, by purchase, lease, merger, consolidation or otherwise, of the business or assets of any corporation, firm or association, including Grants to employees thereof who become Employees, or for other proper corporate purposes, or (ii) limit the right of Verticalnet to grant stock options or make other awards outside of this Plan. Without limiting the foregoing, the Committee may make a Grant to an employee of another corporation who becomes an Employee by reason of a corporate merger, consolidation, acquisition of stock or property, reorganization or liquidation involving Verticalnet in substitution for a grant made by such corporation. The terms and conditions of the substitute Grants may vary from the terms and conditions required by the Plan and from those of the substituted stock incentives. The Committee shall prescribe the provisions of the substitute Grants.

(b) Compliance with Law. The Plan, the exercise of Options and the obligations of Verticalnet to issue or transfer shares of Stock under Grants shall be subject to all applicable laws and to approvals by any governmental or regulatory agency as may be required. With respect to persons subject to section 16 of the Exchange Act, it is the intent of Verticalnet that the Plan and all transactions under the Plan comply with all applicable provisions of Rule 16b-3 or its successors under the Exchange Act. In addition, it is the intent of Verticalnet that the Plan and applicable Grants comply with the applicable provisions of sections 162(m), 409A and 422 of the Code. To the extent that any legal requirement of section 16 of the Exchange Act or sections 162(m), 409A or 422 of the Code as set forth in the Plan ceases to be required under section 16 of the Exchange Act or sections 162(m), 409A or 422 of the Code, that Plan provision shall cease to apply. The Committee may revoke any Grant if it is contrary to law or modify a Grant to bring it into compliance with any valid and mandatory government regulation. The Committee may also adopt rules regarding the withholding of taxes on payments to Participants. The Committee may, in its sole discretion, agree to limit its authority under this Section.

(c) Enforceability. The Plan shall be binding upon and enforceable against Verticalnet and its successors and assigns.

(d) Funding of the Plan; Limitation on Rights. This Plan shall be unfunded. Neither Verticalnet nor any other Company shall be required to establish any special or separate fund or to make any other segregation of assets to assure the payment of any Grants under this Plan. Nothing contained in the Plan and no action taken pursuant hereto shall create or be construed to create a fiduciary relationship between Verticalnet or any other Company and any Participant or any other person. No Participant or any other person shall under any circumstances acquire any property interest in any specific assets of Verticalnet or any other Company. To the extent that any person acquires a right to receive payment from Verticalnet hereunder, such right shall be no greater than the right of any unsecured general creditor of Verticalnet.

(e) Rights of Participants. Nothing in this Plan shall entitle any Employee, Consultant, Non-Employee Director or other person to any claim or right to receive a Grant under this Plan. Neither this Plan nor any action taken hereunder shall be construed as giving any individual any rights to be retained by or in the employment or service of the Company.

(f) No Fractional Shares. No fractional shares of Stock shall be issued or delivered pursuant to the Plan or any Grant. The Committee shall determine whether cash, other awards or other property shall be issued or paid in lieu of such fractional shares or whether such fractional shares or any rights thereto shall be forfeited or otherwise eliminated.

(g) Employees Subject to Taxation Outside the United States. With respect to Participants who are subject to taxation in countries other than the United States, the Committee may make Grants on such terms and conditions as the Committee deems appropriate to comply with the laws of the applicable countries, and the Committee may create such procedures, addenda and subplans and make such modifications as may be necessary or advisable to comply with such laws.

(h) Governing Law. The validity, construction, interpretation and effect of the Plan and Grant Letters issued under the Plan shall be governed and construed by and determined in accordance with the laws of the Commonwealth of Pennsylvania, without giving effect to the conflict of laws provisions thereof.
