Dear Marchai:

On behalf of the combined Broadbase/Servicesoft Management and Board of Directors, we are pleased to detail your terms of employment. Our combined company is a major force in the eCRM market and its greatest asset is
employees like yourself. We are proud of the accomplishments of Broadbase and Servicesoft individually, and look forward to continued success as we combine two great institutions.

You will hold the position of VP Channel Alliances, reporting to Andy Kieffer.

This letter outlines the proposed terms of your anticipated employment with Broadbase.



| |  |  | Your annual salary will be $135,000.00 or $5,625.00 paid semi-monthly. This salary will be subject to review as part of the upcoming annual performance evaluation
review process to be completed for Servicesoft employees in January.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | You currently have 29696 Servicesoft options that will be converted to 42773 options of Broadbase Software upon the merger. The purchase price of the shares covered
by the option will be the existing exercise price of your respective options, divided by 1.4404 (the conversion ratio). Your original vesting schedule with respect to your existing Servicesoft options will carry over to the converted
Broadbase options.

| |  |  | In addition to the Broadbase options received from the conversion of your Servicesoft options, you will also be granted 15000 options to purchase Broadbase common
shares at a price equal to the closing price of Broadbase shares at the effective date of the grant (which will be on or shortly after the closing of the merger). The grant is subject to approval by the Board of Directors after the closing of the
merger and will be governed by the terms set forth in the Companys standard stock option agreement. Assuming you remain an employee, the option will vest over a 4-year period on a monthly basis commencing on December 15, 2000.

You employment at Broadbase is contingent upon your signing the attached Employee Invention Assignment, Confidentiality and Arbitration
Agreement. An executed copy of this Agreement will need to be submitted to Michael McCormack, Director of Human Resources, for holding on our behalf, by close of business on Wednesday, December 20, 2000.

The following is an amendment to your offer letter dated December 15, 2000. You will be eligible for separation benefits in one of the following two situations:

First, in the event of a Change in Control Event (as defined below), then (a) 100% of the unvested shares under the stock option described above at
the time of such Change in Control Event shall immediately vest, subject to the terms of the Companys stock option agreement, and (b) in such event, you will also receive a lump-sum separation payment of six (6) months annual base
salary. Second, in the event your employment is terminated without Cause, you will receive a lump sum separation payment of six (6) months annual base salary.

A Change in Control Event shall mean a change in control of 50% or more of the outstanding stock of the Company, and following such change you are not offered the same or a similar position with the combined entity as held prior
to the change of control, or you are terminated without Cause within six months following such change. The separation benefits identified herein shall not apply should your employment be terminated for Cause. Cause for your termination

(i) your gross negligence or willful misconduct in the
performance of, or his failure or refusal to perform, his duties with the Company, as determined by the Companys Board of Directors in good faith;
