         * to be adjusted based on actual square footage

4.       Additional Rent. Tenant will pay Tenant's Proportionate Share of
         Operating Expenses with respect to the Expansion Space. On the
         Effective Date, Tenant's Proportionate Share under the Lease for the
         Leased Premises shall be increased to 46.06%. The total square feet of
         Buildings 1 and 2 in the Project is 119,422 square feet.

5.       Tenant Improvements. Landlord shall cause The Bainey Group as general
         contractor to complete the Expansion Space in accordance with the plans
         or the description of improvements and the specifications to be
         prepared by WCL Associates, Inc. Prior to January 1, 2001, Tenant will
         submit complete and final space plans and specifications prepared by
         WCL Associates, Inc., to Landlord for review and approval. Landlord
         will use all reasonable efforts to cause all necessary construction to
         be substantially completed ready for use and occupancy by Tenant on the
         Effective Date, subject to extension for delays due to any cause beyond
         the reasonable control of Landlord or Landlord's contractors or
         suppliers. All construction shall be done in a good and workmanlike
         manner and shall comply at the time of completion with all applicable
         laws and requirements of the governmental authorities having
         jurisdiction. Landlord agrees to complete such construction at Tenant's
         sole expense equal to the aggregate of all costs, expenses and fees
         incurred by or on behalf of Landlord in connection therewith (the
         "Tenant's Cost"), including without limitation (i) architectural,
         engineering and design costs, (ii) the cost charged to Landlord by
         Landlord's general contractor and all subcontractors for performing
         such construction, (iii) the cost to Landlord of performing directly
         any portion of such construction, and (iv) an administrative and
         construction management fee for Landlord's supervision of such
         construction in an amount equal to ___________ percent (____%) of the
         aggregate costs incurred by or on behalf of Landlord in connection with
         such construction. Landlord agrees to credit Tenant with an allowance
         equal to the lesser of the Tenant's Cost or $10.00 per square foot of
         the Leased Premises (the "Tenant Allowance"),. Tenant agrees to pay to
         Landlord, within ten (10) days of being billed therefor, the excess (if
         any) of the Tenant's Cost above the Tenant Allowance. In addition,
         Landlord agrees to make repairs, replacements and maintenance to the
         existing mechanical and electrical systems in the Leased Premises not
         to exceed One Hundred Thousand Dollars ($100,000).

6.       Parking. Section 5 of the Lease is amended to provide that as of the
         Effective Date, there shall be 187 parking spaces available for Tenant
         at all times at the Building and no more


                                       2
<PAGE>


         than 187 parking spaces are to be occupied at any one time by the
         Tenant, its employees and invitees.

7.       Waiver. Tenant waives all rights of expansion and rights to renew under
         the Lease including but not limited to Section 32 of the Lease, and the
         rights to expand the Leased Premises, Cancellation Option, and Option
         to Renew as provided in the Amendment to Lease dated April 18, 1996.

8.       Remedies. The following language is hereby added to Section 15 of the
         Lease:

         "In the event of a Default, Landlord will have the following rights:

                  (i) To charge a late payment fee equal to the greater of $100
         or 5% of any amount owed to Landlord pursuant to the Lease which is not
         paid within 5 days after the due date; and

                  (ii) To enter and repossess the Leased Premises in compliance
         with all laws and remove all persons and all or any property therefrom,
         by action at law or otherwise, without being liable for prosecution or
         damages therefor, and Landlord may, at Landlord's option, make
         alterations and repairs in order to relet the Leased Premises and relet
         all or any part(s) of the Leased Premises for Tenant's account. Tenant
         agrees to pay to Landlord on demand any deficiency that may arise by
         reason of such reletting. In the event of reletting without termination
         of this lease, Landlord may at any time thereafter elect to terminate
         the Lease for such previous breach.

9.       Contingency. This Amendment is contingent upon vacation of the
         Expansion Space by G. N. Resound Corp., the current occupant of the
         Expansion Space.

10.      Right of First Opportunity. In the event any space at 5600 Rowland Road
         becomes available for lease at any time during the term of this Lease
         and any current occupants do not desire to remain in possession,
         Landlord shall give Tenant written notice of the availability of such
         space. Landlord will not enter into a binding agreement to lease such
         space to any third party for a period of 14 days following such notice
         of availability. The notice period is intended to afford Tenant the
         first opportunity to negotiate the lease of such space with Landlord.

11.      Lease in Full Force. Except as expressly amended by this Agreement, all
         of the terms and conditions the Lease remain unmodified and continue in
         full force and effect. All capitalized terms used herein and not
         separately defined herein shall bear the meaning assigned to them in
         the Lease.
