Dear Peter:

     This letter agreement (the "Agreement") confirms the agreement that we 
have reached regarding the termination of your employment from Primix 
Solutions Inc. (the "Company"). The purpose of this Agreement is to establish 
an amicable arrangement for ending your employment relationship, to release 
the Company from any claims that you may have against it or any related 
companies, to release you from any claims that the Company or any related 
companies may have against you, and to permit you to receive separation pay 
and related benefits.

     With those understandings and in exchange for the promises of you and 
the Company set forth below, you and the Company agree as follows:

     1. TERMINATION

     Your employment with the Company will terminate effective February 15, 
1999 (the "Termination Date"). To the extent that the Company has not already 
done so, the Company shall pay to you on the Termination Date all base salary 
accrued to and including the Termination Date and 1.25 days of vacation pay, 
constituting all accrued but unused vacation pay due to you to and including 
the Termination Date.

     2. SEVERANCE PAY

     The Company shall mail a check to you in the amount of $120,000.00, less 
applicable taxes and withholdings the Company determines to be required for 
tax purposes. The check shall be made payable to you. The Company shall mail 
the check within five (5) business days of February 15, 1999.

     3. BENEFITS

     Your eligibility to participate in the Company's health and dental plans 
ceases on or after the Termination Date in accordance with the terms and 
conditions of each of the health and dental plans, subject to your rights to 
continue certain benefits in accordance with and subject to the law known as 
COBRA. The Company agrees to pay all COBRA payments for the period beginning 
on February 15, 1999 and concluding on October 15, 1999. You will be notified 
of your rights under COBRA within thirty (30) days after the Termination Date.

     4. CONSULTING FEES

     Beginning on February 16, 1999, the Company and you agree that the Company 
will be obligated to pay you for two months of consulting fees, at a rate of 
$20,000 per month. The fees will be paid to you in the lump sum of $40,000, 
less applicable taxes and withholdings the Company determines to be required 
for tax purposes. The Company shall mail the check within five (5) business 
days of February 15, 1999. The consulting fees paid to you will be 
non-refundable, unless you materially breach the terms of this agreement. The 
scope of services rendered shall be agreed upon between you and Lennart 
Mengwall, the Company's Chairman and Chief Executive Officer. You will have 
no obligation to perform consulting services to the Company under this 
agreement. Your election to not perform consulting services under this 
agreement does not release the Company from its obligation to pay the 
consulting fees as defined herein.

     5. EXPENSE REIMBURSEMENT

     The Company shall reimburse you for any job-related expenses you incurred 
through the Termination Date or as a result of consulting work you perform for 
the Company, consistent with the Company's expense reimbursement policy. In 
order to receive reimbursement for any such expenses, you must submit any and 
all expense reports in writing to David Chapman, Chief Financial Officer 
prior to May 15, 1999.

     6. CLAIMS

     You on the one hand and the Company and any of its affiliates, 
subsidiaries, predecessors, successors, and assigns of each of them, and the 
current and former officers, directors, employees and agents of each of the 
foregoing (any and all of which are referred to as the "Company and its 
Related Parties") on the other hand agree voluntarily to release and 
discharge each other generally from all charges, complaints, claims, 
promises, agreements, causes of action, damages, and debts of any nature 
whatsoever, known or unknown, up to the date of this Agreement, which either 
you or the Company and its Related Parties have, claim

to have, ever had, or ever claimed to have had against the other. 
Notwithstanding anything in the preceding sentence to the contrary, this 
mutual general release shall not be construed to limit your right to enforce 
this Agreement.

     7. STOCK OPTIONS

     You acknowledge and agree that none of the Stock Options granted to 
you pursuant to March 13, 1998 Incentive Stock Option Agreement and March 13, 
1998 Non-Qualified Stock Option Agreement entered into between you and the 
Company have vested as of the Termination Date. The Stock Options therefore 
terminated as of the Termination Date. You do not have any claim or 
entitlement to the Company's stock.

voluntarily. You also acknowledge that you are not relying on any 
representations by me or any other representative of the Company concerning
