                             [LETTER HEAD OF N2H2]

                    SEPARATION AGREEMENT AND GENERAL RELEASE

         This Separation Agreement and General Release (this "Separation
Agreement") is entered into by and between Cher Paige (subsequently referred to
as Paige) and N2H2, Inc. (subsequently collectively referred to as the
"Company").

         Both parties to this Agreement wish to clearly set forth the terms and
conditions of Paige's termination of employment with the Company.

         In exchange for the Enhanced Separation Package as outlined herein, the
Company and Paige agree as follows:

         1.       EMPLOYMENT/FINAL PAY: Because of a reorganization and
reduction in force, Paige's employment with the Company is discontinued as of
September 9, 2002. The Company agrees to pay Paige his/her normal salary through
September 9, 2002, less all required or agreed upon withholding. Paige
acknowledges that he/she has been paid through September 9, 2002, and that
he/she is owed no additional compensation of any kind except as described in
this Separation Agreement.

         2.       VACATION LEAVE:  The Company will pay to Paige all of his/her
accrued but unused vacation leave with the paycheck which corresponds to the
payroll period which included Paige's termination date. All normal and agreed
upon withholding will be deducted from this payment.

         3.       COMMISSIONS:  If Paige is generally compensated in all or part
by commissions, Company will pay Paige his/her quarterly commissions consistent
with the standard commission payment schedule, generally within 30 days of the
end of the quarter, September 30, 2002.

         4.       SEPARATION PAY:  The Company will also pay Paige 3 months base
salary, less normal or agreed upon withholding as Separation Pay. This amount
shall be paid in a lump sum no later than 7 days after the effective date of
this Separation Agreement.

         5.       COBRA: Until September 30, 2002, Company will continue its
contributions towards Paige's group medical and dental insurance, as well as
Paige's group long term and short term disability insurance. As of October 1,
2002, Paige and any eligible dependents shall have the right to purchase group
medical &/or dental continuation coverage through the Company pursuant to
his/her rights under the COBRA statute and regulations. If Paige elects COBRA
continuation coverage, the Company will pay 100% of the premium for coverage of
Paige and 100% of Paige's dependent premiums for up to three months. After three
months of COBRA, Paige must self-pay to continue his/her COBRA coverage.

         6.       STOCK OPTIONS: Paige may exercise vested stock options he/she
is entitled to receive under the terms of the Company's Stock Option Plan and
Paige's Stock Option Agreement. If Paige desires to exercise any vested options,
he/she will do so according to the Plan terms. All unvested stock options will
expire according to the Plan terms.

Agreement to any person other than Paige's attorneys, accountants, tax advisors
