Termination Depending upon the reason for your employment with GXS ending, you will be
covered by one of the following: (1) Cause or Voluntarily Quit If your employment terminates because you voluntarily quit or because GXS

compensation. Cause shall include, but not be limited to: willful or
unreasonable neglect of your job duties, committing fraud, misappropriation or
embezzlement; dishonesty; insubordination; being convicted of a felony; willful
unauthorized disclosure of GXS confidential information; and willfully or
unreasonably engaging in conduct materially injurious to GXS. (2) Termination Without Cause If you are terminated without cause you would receive, as severance,
continuation of your then current salary and medical benefits for twelve months
and a pro rated portion of your most recent annual bonus payment. This payment
would be subject to your signing GXSs standard termination agreement, which
would include (i) non-competition and non-solicitation commitments by you for a
period of twelve months, and (ii) a complete release for the benefit of GXS. In the event of a Change of Control (as defined in the GXS Holdings, Inc. Stock
Incentive Plan) and you are not offered a position comparable to your position
as Senior Vice President for GXSs Global Operations and Global Information
Technology organizations following the Change in Control and you terminate your
employment with GXS, or its successor, as a result then such termination will
be deemed to be a Termination Without Cause. In the event of any termination of your employment, you will be required to
reimburse GXS for any outstanding monies owed to GXS that have not been repaid
by the time employment is terminated. Acceptance of this letter will be your
authorization to permit GXS, to the extent permitted by law, to deduct and
offset any payments, including payment for salary, bonus, expenses, or vacation
pay, otherwise owed to you upon termination of employment. Confidentiality/Integrity This offer is made in the strictest confidence. You are required to maintain
