3. Subleased Premises and Rent:

      3.1 Subleased Premises:

of Fourteen Thousand Two Hundred fifty-nine and 80/100 Dollars ($14,259.80)

subleased to Sublessee on a gross/full service basis and that Sublessee 
shall not be liable for the payment of any costs or expenses relating to 
Operating Expenses. Taxes, Insurance, Utilities or repairs (as those terms

each calendar month during the Sublease Term. If the Sublease commencement 
date or the termination date of the Sublease occurs on a date other than the

calendar month in which the Sublease termination date occurs, respectively.

      3.3 Security Deposit:
In addition to the Rent specified above, Sublessee shall pay to Sublessor an

receipt of notice from the Lessor of an Event of Default or actual knowledge 
of such impairment. If Sublessor terminates the Master Lease, Sublessor 
shall so notify Sublessee by giving at least 30 days notice prior to the 
effective date of such termination.

7. Broker Fee:
Upon execution of the Sublease, Sublessor shall pay Cornish & Carey

improvements, alterations or other work required on or to the Subleased 
Premises or to any other portion of the property and/or building of which 
the Subleased Premises are a part, required or reasonably necessary because 
of: (1) Sublessee's use of the Subleased Premises or any portion thereof; 
(2) the use by a Sublessee by reason of assignment or sublease; or (3) both, 
including any improvements, alterations or other work required under the 
Americans With Disabilities Act of 1990. Compliance with the provisions of 
this Section 8 shall be a condition of Sublessor granting its consent to any 
assignment or Sublease of all or a portion of this Sublease and the 
Subleased Premises described in this Sublease.

9. Compliance With Nondiscrimination Regulations:
It is understood that it is illegal for Sublessor to refuse to display or 
sublease the Subleased Premises, or to assign, surrender or sell the Master 
Lease, to any person because of race, color, religion, national origin, sex, 
sexual orientation, marital status or disability.

10. Toxic Contamination Disclosure:
Sublessor and Sublessee each acknowledge that they have been advised that 
numerous federal, state, and/or local laws, ordinances and regulations 
("Laws") affect the existence and removal, storage, disposal, leakage of and 
contamination by materials designated as hazardous or toxic, or in any way a 
danger to human health or the environment ("Toxics"). Many materials, some 
utilized in everyday business activities and property maintenance, are 
designated as hazardous or toxic.

Some of the Laws require that Toxics be removed or cleaned up by landowners, 
future landowners or former landowners without regard to whether the party 
required to pay for "clean up" caused the contamination, owned the property 
at the time the contamination occurred or even knew about the contamination. 
Some items, such as asbestos or PCBs, which were legal when installed, now 
are classified as Toxics, and are subject to removal requirements. Civil 
lawsuits for damages resulting from Toxics may be filed by third parties in 
certain circumstances.

Sublessor and Sublessee each acknowledge that Broker has no specific 
expertise with respect to environmental assessment or physical condition of 
the Subleased Premises, including, but not limited to,


                                      3


<PAGE>    58




matters relating to: (i) problems which may be posed by the presence or 
disposal of hazardous or toxic substances on or from the Subleased Premises, 
(ii) problems which may be posed by the Subleased Premises being within the 
Special Studies Zone as designated under the Alquist-Priolo Special Studies 
Zone Act (Earthquake Zones), Section 2621-2630, inclusive of California 
Public Resources Code, and (iii) problems which may be posed by the 
Subleased Premises being within a HUD Flood Zone as set forth in the U.S. 
Department of Housing and Urban Development "Special Flood Zone Area Maps," 
as applicable. 

Sublessor and Sublessee each acknowledge that Broker has not made an 
independent investigation or determination of the physical or environmental 
condition of the Subleased Premises, including, but not limited to, the 
existence or nonexistence of any underground tanks, sumps, piping, toxic or 
hazardous substances on the Subleased Premises. Sublessee agrees that it 
will rely solely upon its own investigation and/or the investigation of 
professionals retained by it or Sublessor, and neither Sublessor nor 
Sublessee shall rely upon Broker to determine the physical and environmental 
condition of the Subleased Premises or to determine whether, to what extent 
or in what manner, such condition must be disclosed to potential sublessees, 
assignees, purchasers or other interested parties.

11. Rent Abatement and Damages to Personal Property:
In the event Sublessor, pursuant to the terms of the Master Lease, is 
entitled to and receives rent abatement, then to the extent such rent 
abatement affects the subleased premises, Sublessee shall be entitled to 
rent abatement in an amount that the net rentable area of the subleased 
premises bears to the total net rentable area of the Master Lease, and only 
to the extent any such abatement applies to the sublease term. In addition, 
any amounts paid or credited to Sublessor under the terms of the Master 
Lease for damage to personal property shall be credited to Sublessee, 
subject to the same limitations set forth above.
