         The purpose of this Separation Agreement ("Agreement") is to set forth
the terms and conditions under which Employee and Employer will terminate their

         In consideration of the Recital stated above and the mutual promises
made below, the parties agree as follows:

         1.       TERMINATION OF EMPLOYMENT. Employer and Employee hereby agree
                  that the employment relationship between Employer and Employee
                  is terminated effective June 30, 2000 (the "Termination
                  Date"). In addition thereto, Employee hereby resigns all
                  officer and director positions held with Employer including
                  President, Secretary and Director, effective the Termination
                  Date. Unless otherwise agreed, Employer will provide to
                  prospective future employers of Employee a letter including
                  Employee's position with Employer and the beginning and ending
                  dates of employment only. Employee and Employer both agree to
                  refrain from any disparagement of the other party in
                  discussions with third parties. Employer and Employee agree
                  that with the exception of Employee's continuing obligations
                  pursuant to Sections 6 and 7 of this Agreement and Section 4
                  of the Employment Agreement, all rights and obligations of the
                  parties with respect to the employment

                  relationship and the Employment Agreement are terminated
                  effective June 30, 2000.

         2.       SEVERANCE. Employee will receive a severance settlement
                  consisting of Employee's normal salary through June 30, 2000
                  and a lump sum payment of $40,000.00 both subject to lawful
                  and customary withholding for tax and other purposes, which
                  lump sum will be paid to Employee with the payroll period
                  ending June 30, 2000.

         3.       INSURANCE. Employee may continue, to the extent provided by
                  COBRA and other applicable federal and state laws, to
                  participate in group health insurance programs offered by
                  Employer. Current levels of insurance coverage will be
                  maintained at Employer's expense through December 31, 2000.
                  Thereafter, Employee's continued participation shall be
                  dependent upon the timely monthly payment of the full actual
                  cost of the premiums and administrative fees for such
                  insurance.

         4.       COMPENSATION AND BENEFITS. Employee hereby acknowledges and
                  confirms that upon receipt of payments contemplated herein,
                  that he has been fully paid by Employer for all accrued
                  salary, bonuses, performance bonuses, severance pay, vacation
                  pay, sick pay and other compensation through the effective
                  date of termination as an Employee, except to the extent
                  provided in this Agreement, and that he has submitted requests
                  and been fully reimbursed by Employer for all expenses
                  incurred or advanced by him as an employee. Employee
                  specifically agrees that no performance bonuses are due nor
                  shall Employee be paid for any performance bonuses pursuant to
                  the Employment Agreement. Except as set forth below, to the
                  extent that Employee is a participant in employee benefit,
                  stock purchase or stock option plans through the Company, the
                  amount of any benefits or

                                       2
<PAGE>

                  stock purchase rights and options due or payable thereunder
                  and the timing thereof shall be governed by the terms of such
                  employee benefit or stock plans. Specifically, Employee shall
                  be vested in options for 87,917 shares granted to Employee
                  pursuant to an Option Agreement dated October 1, 1999. The
                  options shall be exercisable on December 31, 2000 and for a
                  period of five (5) years thereafter. Employee acknowledges
                  that the modification of the options as provided herein
                  results in the possible loss of favorable tax status accorded
                  statutory options. Notwithstanding any other provisions of the
                  Option Agreement to the contrary, no additional options shall
                  vest pursuant to the Option Agreement.

         5.       RETURN OF PROPERTY. Employee agrees to return to Employer all
                  tangible property of Employer, including financial and
                  business reports and records, price lists, catalogs, and sales
                  and marketing materials and any and all correspondence and
                  documents, that Employee has in his possession, on or before
                  June 30, 2000.

         6.       COOPERATION AND ASSISTANCE. Between the date hereof and June
                  30, 2000, the Employee agrees to provide reasonable
                  cooperation and assistance to the Employer in connection with
                  transition of Employee's duties with Employer, including,
                  without limitation, the submission of all information and the
                  performance of all duties and obligations as directed by the
                  Employer's Board of Directors and Chief Executive Officer.

         7.       PROPRIETARY INFORMATION. Proprietary Information means any
                  information or compilation of information not generally known,
                  relating to the Employer's business which is not readily
                  ascertainable by persons in Employer's line of business and
                  has been expressly or implicitly protected by the Employer
                  from

                  without the prior written consent of Employer. Further,
                  Employee agrees not to directly or indirectly disclose or make

                  reproductions in possession of Employee relating to Employer's
                  business. The provisions of this Section 7 shall be in

                  Section 5 of the Employment Agreement, to the extent
                  applicable, are hereby terminated in all respects upon
                  execution hereof; provided, however, the applicable provisions
                  of Section 4 of the Employment Agreement shall remain in full
                  force and effect.

         9.       RELEASE OF CLAIMS. In consideration of the severance payment
                  to be made to the Employee by Employer, the Employee does
                  hereby release, acquit and forever discharge Employer, and all
