                                 OFFICE LEASE

     This Lease is entered into between John D. Walker, II ("Landlord"), and
Biolynx ("Tenant").

     In consideration of the mutual covenants and agreements of this lease, and
other good and valuable consideration, Landlord demises and leases to Tenant,
and Tenant leases from Landlord, suite number 110, comprising approximately 2650
square feet of space, located on the first floor of the Building A, 5617 Grissom
Road, San Antonio, Bexar County, Texas, legally described on Exhibit A attached
to this lease, and made a part of this lease for all purposes. The premises are
referred to in this lease as "the premises" or "the leased premises."

                                ARTICLE 1. TERM

                                 Term of Lease

     1.01.  The term of this lease is 36 (thirty-six), months beginning on
November 9, 1998, and ending on November 9, 2001, unless terminated sooner or
extended as provided in this lease.

                              Option to Extend Term

     1.02.  Tenant may extend the term of this lease beyond the expiration date
provided in (S) 1.01 on the following conditions:

     a.  Tenant may, if it is not in default either on the date required for the
notice or on the date such extension commences, extend the lease term for
additional periods of n/a months each. The extended term will begin on the day
following the expiration date of the lease term specified in (S) 1.01, and for
n/a additional periods of the same length, each to begin on the day following
the expiration date of the immediately preceding extended term. But if, on the
date the original term or any extended term expires, Tenant is in default beyond
any grace period provided in this lease in performing any of the terms of this
lease, the remaining option or options are void. All the terms and covenants of
the original lease term apply to all extended lease terms; provided, however,
that in no event shall this lease be in force and effect after n/a, unless
pursuant to holdover under (S) 1.03.

     b. Tenant may exercise each option to extend this lease by giving Landlord
notice of its intention to do so not later than sixty (60) days before the then
current lease term expires, in the case of the initial option to extend, or
before the extended lease term expires, in the case of successive options to
extend. Notice of an intention to exercise an option under this lease must, to
be effective, be sent by mail or fax to Landlord as provided in (S) 15.02 no
later than the latest date provided in this section for Tenant's exercising the
option.

                                    Holdover

     1.03.  If Tenant holds over and continues in possession of the premises
after the lease term (or any extension of it) expires, other than as provided in
(S) 1.02, Tenant will be considered to be occupying the premises on a month-to-
month tenancy, subject to all of the terms of this lease.

                                 ARTICLE 2. RENT

                                   Basic Rent

     2.01.  Tenant will pay Landlord $3,000.00 per month, from the beginning of
the lease term and throughout the original lease term, in advance on the 9th
(ninth) day of each month without deduction or setoff. This amount is the "basic
rent." Rent for any fractional month at the beginning or end of the lease term
will be prorated on a per-day basis. This basic rent will increase by n/a
percent for each extended lease term, so that the basic rent during the first
extended term will be $ n/a; the basic rent during second extended term will be
$ n/a; and so forth.

                               Security Deposit

     2.02. a. Tenant has deposited with Landlord the additional sum, equal to
one month's rent, of ________________ and 00/100 Dollars ($__________) which
Landlord acknowledges receiving, as security for Tenant fully and faithfully
performing the terms and covenants of this lease to be performed and kept on
Tenant's part. This deposit does not constitute advance payment of the final
rental payment due under this lease.

     b.    Landlord will hold the deposit for Tenant, and it is understood
that Tenant's claim to the deposit is prior that of any creditor of Landlord's,
excluding a trustee in bankruptcy.

     c.    Excluding the final rental payment to be made under this lease,
if, at any time during the lease term, Tenant defaults in paying rent or any
portion of rent reserved in this lease, or any other sums expressly constituting
rent, other than advance rental payments, Landlord may appropriate and apply any
portion of the security deposit as may be necessary to pay the overdue rent or
other sums expressly constituting rent under this lease.

     d.    If, at any time during this lease term, Tenant fails to repair any
damage to the premises that Tenant must repair under this lease for a period
greater than ten (10) days after Landlord serves on Tenant written demand to
make the repair, the Landlord may appropriate and apply any portion of the
security deposit as may be reasonably necessary to make the repairs.

     e.    If, on termination of this tenancy for any reason, Tenant does not
leave the premises in reasonably clean condition and in good repair, excluding
normal wear and tear, then Landlord may appropriate and apply any portion of the
security deposit as may be reasonably necessary to put the premises in clean
condition and good repair. As used in this lease, "normal wear and tear" means
deterioration that results from the intended use of the Property, and does not
include deterioration that results from negligence, carelessness, accident, or
abuse of the premises by Tenant, Tenant's employee, or Tenant's guest.

     f.    If there is actual cause for retaining all or any portion of the
security deposit, Landlord will return to Tenant the balance, if any, together
with a written description and itemized list of all deductions. Such deductions
will be limited to damages and charges for which Tenant are legally liable under
this agreement or as a result of breaching it. Landlord is not required to
furnish a description and itemized list of deductions if any rentals are due and
unpaid when Tenant surrenders possession of the premises and there is no
controversy over the amount of rentals due and unpaid.

     g.    Within thirty (30) days Tenant surrenders the premises, any
remaining portion of the security deposit, after any lawful deductions as above,
will be returned to Tenant at the address left by Tenant specifically for that
purpose. BUT TENANT IS NOT ENTITLED TO ANY PORTION OF THE SECURITY DEPOSIT AS A
REFUND UNLESS TENANT GIVE LANDLORD SIXTY (60) DAYS NOTICE OF SURRENDERING THE
PREMISES.

     h.    If Landlord transfers Landlord's interest under this lease in any
manner, Landlord or his agent must do one of the following, either of which will
relieve Landlord or his agent of further liability with respect to the deposit:

         (1)  Transfer the portion of the deposit remaining after any lawful
     deductions, as above, to the successor in interest, and then notify Tenant
     by registered mail of the transfer and of the transferee's name and
     address. On receiving the remaining deposit, Landlord's successor in
     interest will have all of Landlord's rights with respect to the deposit. On
     Tenant's receiving a statement signed by the successor in interest
     acknowledging receipt of and responsibility for the security deposit,
     Landlord's successor in interest will have all of Landlord's obligations
     with respect to the deposit.

         (2)  Return to Tenant the portion of the deposit remaining after any
     lawful deductions have been made.

threatened breach by Employee of any of his or her covenants herein and that any
such breach by Employee will cause the Company irreparable damage. Accordingly,

additional remedies otherwise available to it, to injunctive and other equitable
relief in the event of a breach or threatened breach. The validity and
interpretation of this agreement and legal relations of the parties shall be
