                              EMPLOYMENT AGREEMENT

                              (Christopher G. Kuhn)

This EMPLOYMENT AGREEMENT, dated December 16, 2002 (this "AGREEMENT"), is
between Verticalnet, Inc., a Pennsylvania corporation (the "COMPANY"), and
Christopher G. Kuhn (the "EMPLOYEE").

The Company and the Employee, each intending to be legally bound by this
Agreement, agree as follows:

1. Employment

This Agreement is effective December 16, 2002 (the "EFFECTIVE DATE"). The
Employee shall be Vice President and General Counsel of the Company and shall
perform duties consistent with this position as are assigned by the Chief
Executive Officer or the Board of Directors of the Company (the "BOARD"). The
Employee shall report directly to the Chief Executive Officer and be an officer
of the Company.

2. Performance

The Employee shall devote substantially all of his business time and efforts to
the performance of his duties under this Agreement, however, the Employee may
(a) serve on civic or charitable boards or committees, (b) serve on corporate
boards as a non-employee board member and (c) manage Employee's personal
investments. The Employee must inform the Company of any corporate boards on
which he serves. The Employee cannot serve on any corporate board that would
violate the Employee's non-competition restrictions.

3. Term

The initial term of employment under this Agreement (the "INITIAL TERM") begins
on the Effective Date and extends for 1 year. This Agreement renews
automatically for one year renewal terms (a "RENEWAL TERM") unless either the
Employee or the Company gives the other party written notice of non-renewal at
least one year before the end of the Initial Term or any Renewal Term then in
effect. The Agreement renews automatically for a 1 year Renewal Term upon a
Change of Control, as defined in Section 12, beginning on the date of the Change
of Control. The Initial Term plus any Renewal Term then in effect are the term
of this Agreement (the "EMPLOYMENT TERM"). The Employment Term may be terminated
early as provided in Sections 7 through 12 of this Agreement.

4. Salary

The Employee's annual salary (the "SALARY") is payable in installments when the
Company customarily pays its officers (but no less often than twice per month).
The Salary is at the initial rate of $165,000 (the "INITIAL SALARY"), effective
retroactively to October 1, 2002. The portion of the Salary due from October 1,
2002 through and including December 31, 2002 shall be paid in a single, lump sum
payment on January 1, 2003 or the pay date encompassing such date. The Board or
the Compensation Committee shall review the Salary at least once a year. The
Salary shall never be less than the Initial Salary.

5. Bonus and Benefits

The Employee shall be entitled to participate in any bonus programs established
by the Board or the Compensation Committee for officers generally. All bonus
programs are at the discretion of the Board or the Compensation Committee.

Benefits and perquisites under this agreement will, at a minimum, be consistent
with other Company Vice Presidents. Vacation shall be in accordance with Company
policy, but not less than 4 weeks per year.

6. Confidential Information, Non-Competition and Non-Solicitation.

The Employee agrees to be covered by the terms of the Confidential Information,
Invention and Non-Competition Agreement that the Employee has entered into upon
the commencement of employment with the Company (the "CONFIDENTIAL INFORMATION,
INVENTION AND NON-COMPETITION AGREEMENT"), which subject to the next following
paragraph, includes a one year

<PAGE>

period of non-solicitation of employees and customers, and non-competition after
termination of employment.

7.   Death

If the Employee dies during the Employment Term, then the Employment Term shall
terminate, and thereafter the Company shall not have any further liability or
obligation to the Employee, the Employee's executors, administrators, heirs,
assigns or any other person claiming under or through the Employee, except (a)
that the Employee's estate shall receive any unpaid Salary that has accrued
through the date of termination, and a pro rata portion of any bonus that the
Employee would have earned for the fiscal year of the Company in which the
Employee died, evaluated and paid in the case of individual MBOs for the
Employee, no later than one month after the date of termination, and in the case
of MBOs applying generally to senior officers, no later than March 31st of the
year following the calendar year to which the bonus relates or, if earlier, when
bonuses for such year are paid to executives generally, (b) the Employee's
outstanding options are accelerated for an additional period of 6 months so that
any of the Employee's options that were scheduled to vest over the 6 month
period after the Employee's death shall accelerate and be vested on the date of
death. By the terms of the options, all vested options (included accelerated
options) are exercisable for one year from the date of death.

8.   Total Disability

If the Employee becomes "totally disabled," then the Employment Term shall
terminate, and thereafter the Company shall have no further liability or
obligation to the Employee hereunder, except as follows: the Employee shall
receive (a) any unpaid Salary that has accrued through the date of termination,
(b) continued Salary for 3 months following the date the Employee is considered
totally disabled, (c) a pro rata portion of any bonus that the Employee would
have earned for the fiscal year of the Company in which the Employee became
totally disabled, evaluated and paid in the case of individual MBOs for the
Employee, no later than one month after the date of termination, and in the case
of MBOs applying generally to officers, no later than March 31st of the year
following the calendar year to which the bonus relates or, if earlier, when
bonuses for such year are paid to officers generally, (d) whatever benefits that
he may be entitled to receive under any then existing disability benefit plans
of the Company.

The term "TOTALLY DISABLED" means: (a) if the Employee is considered totally
disabled under the Company's group disability plan in effect at that time, if
any, or (b) in the absence of any such plan, under applicable Social Security
regulations.

9.   Termination for Cause

The Company may terminate the Employee for "cause" immediately upon notice from
the Company. If the Employee is terminated for "cause", then the Employment Term
shall terminate and thereafter the Company shall not have any further liability
or obligation to the Employee, except that the Employee shall receive any unpaid
Salary that has accrued through the date of termination.

The term "CAUSE" means: (a) the Employee is convicted of a felony, or (b) in the
reasonable determination of the Board, the Employee has done any one of the
following: (1) committed an act of fraud, embezzlement, or theft in connection
with the Employee's duties in the course of his employment with the Company, (2)
caused material intentional, wrongful damage to the property of the Company, (3)
materially breached (other than by reason of illness, injury or incapacity) the
Employee's obligations under this Agreement or under any written
confidentiality, non-competition, or non-solicitation agreement between the
Employee and the Company, that the Employee shall not have remedied within 30
days after receiving written notice from the Board specifying the details of the
breach, or (4) engaged in gross misconduct or gross negligence in the course of
the Employee's employment with the Company.

10.  Termination by the Employee

The Employee may terminate this Agreement by giving the Company written notice
of termination two weeks in advance of the termination date. The Company may
waive this notice period and set an earlier termination date. If the Employee
terminates this Agreement, then on the termination date, the Employment Term
shall terminate and thereafter the Company shall have no further liability or
obligation to the Employee under this Agreement, except that the Employee shall
receive

<PAGE>

any unpaid Salary that has accrued through the termination date. After the
termination date, the Employee shall be required to adhere to the covenants
against non-competition and non-solicitation described in Section 6 of this
Agreement.

Notwithstanding the first paragraph of this Section 10, if without the
Employee's prior written consent or resignation, the Company or the Board takes
an action that constitutes "Good Reason," as defined in Section 12, then during
the period beginning with any such action and ending 6 months thereafter, the
Employee shall have the right to terminate this Agreement by giving the Company
written notice of termination, and upon termination the Employee shall receive
the same compensation and benefits as if the Employee were terminated without
"cause" by the Company under Section 11.

11.  Termination without Cause by the Company

The Company may terminate the Employee without "cause" by giving the Employee
written notice of termination one month in advance of the termination date. The
Employee may waive this notice period and set an earlier termination date.

If the Employee is terminated without "cause", then the Employment Term shall
terminate and thereafter the Employee shall be entitled only to the following
under this Agreement:

          a.   The Company will pay to the Employee a lump sum severance payment
               in the amount equal to one-quarter (i.e. three (3) months) of the
               Salary then in effect; and

          b.   The Company will also pay to the Employee the pro rata portion of
               any Bonus that the Employee would have earned for the fiscal year
               of the Company in which the Employee was terminated, which shall
               be paid within 90 days after the end of such fiscal year, or at
               the time that bonuses are paid to officers for such fiscal year,
               if earlier than 90 days after the fiscal year; and

          c.   The Employee's group healthcare (medical, dental, vision and
               prescription drug) coverage for himself, his spouse and his
               dependents will be continued for 6 months after termination on
               the same basis and cost to the Employee as then participating
               before termination, and

          d.   Unvested options granted to the Employee on the Effective Date
               shall be accelerated in full, and

          e.   All options granted on the Effective Date that are vested
               (including accelerated vesting) at termination will remain
               exercisable by their terms for 90 days after termination of
               employment, but not longer than the total life of the options,
               and

          f.   The Employee and the Company will enter into a mutual general
               release.

12. Change of Control

During the 1 year period after a Change of Control, if the Company terminates
the Employee without cause, or if the Employee terminates this Agreement for
"Good Reason" by giving the Company written notice of termination 2 weeks in
advance of the termination date (which the Employee shall have the right to do
during this 1 year period), then, in such event:

          a.   The Company will pay to the Employee a lump sum severance payment
               in the amount equal to one-half (i.e. six (6) months) of
               the annual Salary then in effect; and

          b.   The Company will also pay to the Employee the pro rata portion of
               any Bonus that the Employee would have earned for the fiscal year
               of the Company in which the Employee was terminated, which shall
               be paid within 90 days after the end of such fiscal year, or at
               the time that bonuses are paid to officers for such fiscal year,
               if earlier than 90 days after the fiscal year; and

          c.   The Employee's group healthcare (medical, dental, vision and
               prescription drug) coverage for himself, his spouse and his
               dependents will be continued for 6 months after termination on
               the same basis and cost to the Employee as then participating
               before termination, and

<PAGE>

     d.   Unvested options granted to the Employee on the Effective Date shall
          be accelerated in full, and

     e.   All options granted on the Effective Date that are vested (including
          accelerated vesting) at termination will remain exercisable by their
          terms for 90 days after termination of employment, but not longer than
          the total life of the options, and

     f.   The Employee and the Company will enter into a mutual general release.

The term "CHANGE OF CONTROL" means:

     a.   Any sale, lease, exchange, or other transfer of all or substantially
          all of the assets of the Company to any other person or entity other
          than a wholly-owned subsidiary of the Company (in one transaction or a
          series of related transactions),

     b.   Dissolution or liquidation of the Company,

     c.   When any person or entity, including a "group" as contemplated by
          Section 13(d)(3) of the Securities Exchange Act of 1934, as amended,
          acquires or gains ownership or control (including, without limitation,
          power to vote) of more than 50% of the outstanding shares of the
          Company's voting securities (based upon voting power), or

     d.   Any reorganization, merger, consolidation, or similar transaction or
          series of transactions that results in the record holders of the
          voting stock of the Company immediately prior to such transaction or
          series of transactions holding immediately following such transaction
          or series of transactions less than 50% of the outstanding shares of
          any of the voting securities (based upon voting power) of any one of
          the following: (1) the Company, (2) any entity which owns (directly or
          indirectly) the stock of the Company, (3) any entity with which the
          Company has merged, or (4) any entity that owns an entity with which
          the Company has merged.

The term "GOOD REASON" means:

     a.   The transfer, without the Employee's prior written consent, to a
          location that is more than 50 miles from the Employee's principal
          place of business immediately preceding the transfer (which shall be
          Malvern, Pennsylvania as of the Effective Date),

     b.   If without the Employee's prior written consent or resignation, the
          Company or the Board takes an action resulting in the Employee no
          longer being the General Counsel of the Company,

     c.   A material reduction of the Employee's authority, duties or
          responsibilities after the Employee has provided the Company with
          reasonable notice and an opportunity to cure,

     d.   Any failure of the Company materially to comply with and satisfy the
          terms of this Agreement, or

     e.   The nonrenewal of this Agreement by the Company.

13. Parachute Payment

Notwithstanding anything to the contrary in this Agreement, if the Employee is a
"disqualified individual" (as defined in Section 280G(c) of the Code), and any
severance benefit provided for in this Agreement, together with any other
payments or benefits that the Employee has the right to receive from the Company
and its affiliates, would constitute a "parachute payment" (as defined in
Section 280G(b)(2) of the Code), then the payments under this Agreement (the
Employee shall have the right to specify which) shall be either:

     a.   Reduced (but not below zero) so that the present value of the total
          amount to be received by the Employee under this Agreement and
          otherwise will be one dollar ($1.00) less than three times the
          Employee's "base amount" (as defined in Section 280G of the Code) and
          so that no portion of such amounts received by the Employee shall be
          subject to the excise tax imposed by Section 4999 of the Code or

<PAGE>

     b.   Paid in full, whichever of (a) or (b) produces the better net
          after-tax position for the Employee (taking into account any
          applicable excise tax under Section 4999 of the Code and any
          applicable income tax).

The determination as to whether the reduction provided in clause (a) shall occur
shall be made initially by the Company in good faith. If a reduced payment is
made and through error or otherwise that payment, when aggregated with other
payments from the Company (or its affiliates) used in determining if a
"parachute payment" exists, exceeds one dollar ($1.00) less than three times the
Employee's base amount, then the Employee shall immediately repay such excess to
the Company upon notification that an overpayment has been made and in the event
that the reduction was more than was required, the Company shall immediately pay
the amount that should have been paid to the Employee in the first instance.

14.  Governing Law

This Agreement is governed by Pennsylvania law.

15.  Entire Agreement; Amendments

This Agreement, the Confidential Information, Invention and Non-Competition
Agreement and the option grant letter dated the Effective Date, set forth the
entire understanding among the parties hereto, and shall supercede all prior
employment, severance and change of control agreements and any related
agreements that the Employee has with the Company or any subsidiary, or any
predecessor company.

This Agreement may not be modified or amended in any way except by a written
amendment executed by the Employee and the Company.

16. No Assignment

All of the terms and provisions of this Agreement shall be binding upon and
inure to the benefit and be enforceable by the respective heirs,
representatives, successors (including any successor as a result of a merger or
similar reorganization) and assigns of the parties hereto, except that the
duties and responsibilities of the Employee hereunder are of a personal nature
and shall not be assignable in whole or in part by the Employee.

IN WITNESS WHEREOF, the parties hereto, intending to be legally bound, have
hereunto duly executed this Employment Agreement as of the day and year first
written above.
