               provided, however, that such accommodations are available and
               eSat may apply for the upgrade.

        (e) Stock Options.

               (1)    Grant of Options. Executive shall receive 300,000
                      restricted shares of eSat common stock options (the
                      "Options") with an exercise price of the greater of $4.00
                      per share or the stock price at the time the Options are
                      exercised (the "Exercise Price"). All Options shall be
                      either qualified incentive stock options or non-qualified
                      stock options, as defined by and available pursuant to the
                      terms and conditions of the eSat executive stock option
                      plan in effect at the time the Options are issued at the
                      option of the Executive. All Options issued hereunder
                      shall be Unvested Options and will become Vested Options
                      only as provided in Section 5(e)(2) hereof. For purposes
                      hereof, "Vested Options" shall mean those Options that
                      vest pursuant to the terms of this Agreement. All other
                      Options shall be denoted "Unvested Options."

               (2)    Vesting. The Unvested Options shall vest 100,000 per each
                      year covered by this Agreement, commencing on the
                      Effective Date, and each one year anniversary of the
                      Effective Date thereafter, subject to Section 5(e)(3)
                      below.

               (3)    Accelerated Vesting.

                                            (a) Termination Without Cause. If
                             Executive is terminated without cause, all Unvested
                             Options shall immediately vest. If Executive is
                             terminated for cause (as defined in Section 6(c)
                             below), all Unvested Options shall be forfeited.

                                            (b) Change in Control. All Unvested
                             Options shall immediately vest upon the occurrence
                             of a change in control as defined in Section 7(a)
                             hereof.

                                            (c) Dissolution Event. All Unvested
                             Options shall immediately vest upon the occurrence
                             of a Dissolution Event as defined in Section 7(b)
                             hereof.

               (4)    Exercise of Options. eSat shall loan Executive money
                      sufficient to exercise each Vested Option in exchange for
                      payment obligations evidenced by promissory notes (each a
                      "Note" and collectively, the "Notes") each in the initial
                      principal amount equal to the Exercise

                                       3.
<PAGE>   4

                      Price for 100,000 shares of eSat common stock. The Notes
                      shall bear interest at a rate of 7% and shall be secured
                      by the shares of eSat common stock then being exercised
                      (the "Exercised Shares"). Executive will sign each Note
                      upon exercising each Vested Option. Each Note will be due
                      and payable upon the sale of the Exercised Shares (the
                      "Date of Payment"). If, at the Date of Payment of a Note,
                      the sale price of the Exercised Shares is less than the
                      Exercise Price, a "Shortfall" shall be deemed to exist.
                      For purposes herein, the "Shortfall Amount" shall mean the
                      difference between the sale price and the Exercise Price
                      multiplied by the number of Exercised Shares. Upon the
                      occurrence of a Shortfall, the Note shall be reduced by
                      the Shortfall Amount. The Executive will be under no
                      obligation to pay the Shortfall Amount in the event the
                      first proceeds are insufficient to cover the original
                      payment obligation under a Note.

               (5)    Registration Rights. Executive shall have piggyback
                      registration rights, the grant and terms of which are
                      subject to approval of the eSat Board of Directors.

        (f) Stock Appreciation Rights. eSat anticipates acquiring shares in a
to-be formed joint venture in Asia (the "eSat Asia JV"). In the event that such
shares are acquired by eSat, Executive shall receive 100% of the appreciation on
10% of such shares. For purposes hereof, the appreciation shall be equal to any
increase in value of the shares less the initial value of the shares when they
were acquired by eSat. The Board shall set the initial value and the increased
value of the shares in good faith based on a reasonable allocation of all costs
incurred in connection with the eSat Asia JV. Executive shall receive such
appreciation from eSat upon (i) termination of this Agreement, (ii) the end of
the Term as defined in Section 3 hereof, or (iii) transfer of eSat's interest in
the eSat Asia JV to another party or parties, whichever occurs first. Should the
eSat Asia JV fail to be formed, nothing herein shall be construed as giving
Executive any Stock Appreciation Rights (or similar rights) in eSat or any of
its affiliates.

        6. Termination. This Agreement and the Executive's employment hereunder
may be terminated without any breach of this Agreement at any time only by
reason of and in accordance with the following provisions:

        (a)     Death. The Executive's death.

        (b)     Total Disability. The Executive shall be prevented from
                performing the Executive's duties hereunder by reason of
                becoming totally disabled as hereinafter defined. For purposes
                of this Agreement, the Executive shall be deemed to have become
                totally disabled when (i) the Executive either receives "total
                disability benefits" under (a) Social Security, or (b) eSat's

                                       4.
<PAGE>   5

                disability plan, if any (whether funded with insurance or
                self-funded by eSat), or (ii) the Board of Directors of eSat,
                upon the written report of a qualified physician designated by
                the Board of Directors of eSat or its insurers, shall have
                determined that the Executive has become physically and/or
                mentally incapable of performing the Executive's duties under
                this Agreement on a permanent basis. The foregoing
                notwithstanding, if Executive suffers an illness or injury which
                prevents executive from attending to Executive's duties
                hereunder for a period of six consecutive months during any 12
                month period during the Term, or any subsequent Renewal Term,
                Executive will be considered "totally disabled".

        (c)     Termination by eSat for Cause. eSat may discharge the Executive
                for cause and terminate this Agreement immediately upon written
                notice to the Executive. For purposes of this Agreement, a
                "discharge for cause" shall mean termination of the Executive
                for one or more of the following reasons:

                (1)     Mismanagement or neglect of the Executive's duties as
                        determined by eSat's Board of Directors after notice to
                        the Executive of the particular details thereof and a
                        period of thirty (30) days thereafter within which to
                        cure each such act or acts of mismanagement or neglect,
                        and the failure of the Executive to cure such act or
                        acts within such 30-day periods;

                (2)     Conviction of the Executive by a court of competent
                        jurisdiction of a felony or a crime involving moral
                        turpitude; or

                (3)     The Executive's failure to comply with any material
                        provision of this Agreement that has not been cured
                        within 10 days after notice of such noncompliance has
                        been given by eSat to the Executive.

        (d)    Termination with Notice. Either party may terminate this
               Agreement, for a reason other than as set forth herein or without
               reason at any time upon 90 days written notice to the other
               party.

        (e)    Termination by the Executive for Cause. The Executive may
               terminate this Agreement at any time for Cause. For purposes of
               this Agreement, the term "Cause" shall mean, without the
               Executive's express written consent, the occurrence of any of the
               following circumstances:

               (1)    The assignment to the Executive of duties that are
                      materially inconsistent with the Executive's position with
                      eSat immediately prior to such change or a material
                      adverse alteration or diminution in the nature or status
                      of the Executive's authority, duties or responsibilities
                      from those in effect immediately prior thereto; or

                                       5.
<PAGE>   6

               (2)    Any failure by eSat to comply with any material provision
                      of this Agreement (including the failure by eSat to
                      materially comply with any of the provisions of Sections 4
                      or 5) that has not been cured within 30 days after notice
                      of such noncompliance has been given by the Executive to
                      eSat.

        7. Change of Control/Dissolution Event.

        (a)     In the event eSat merges into, combines or consolidates with, is
                acquired by, sells its assets to, or engages in any other
                transaction or series of related transactions with one or more
                third parties (the "Acquirer") through which, directly or
                indirectly, the Acquirer and its Affiliates (as defined in the
                Rules promulgated under the Securities Act of 1933, as amended)
                obtain beneficial ownership of more than 50% of eSat's
                outstanding voting equity securities (including pre-transaction
                shares or interests owned by the Acquirer and its Affiliates), a
                Change in Control shall have occurred. In the event this
                Agreement is terminated without cause following a Change in
                Control, Executive will receive the compensation set forth in
                Section 8(b).

        (b)     In the event eSat winds up, distributes assets or enters into
                any transaction or series of related transactions through which,
                directly or indirectly, eSat will dissolve, a Dissolution Event
                shall have occurred. In the event this Agreement is terminated
                without cause upon the occurrence of a Dissolution Event,
                Executive will receive the compensation set forth in Section
                8(b).

                sub-sections (a), (b) or (c), the Executive shall be entitled
                only to that compensation which is accrued through the effective
                date of termination. Such compensation includes Base Salary,
                reimbursement for any business expenses incurred prior to
                termination, accrued vacation and accrued earned bonus, if any.

        (b)     In the event this Agreement is terminated pursuant to Section 6,
                sub-sections (d) or (e) or Section 7 (in the event the
                Executive's employment is not continued by the successor entity)
                the Executive shall be entitled to all compensation and benefits
                for a 180-day period following such termination ("Severance
                Pay"). Severance Pay shall be paid by eSat immediately upon
                termination.

                maintain the Confidential Information in strict confidence and
                shall not divulge the Confidential Information to any person,
                corporation or other entity, or use in any manner, or knowingly
                allow another to have access to the Confidential Information.

        (c)     Executive agrees that, except as required in the performance of
                Executive's duties, Executive will not, at any time during
                Executive's employment or any time after the termination of
                Executive's employment, use, publish, or otherwise disclose in
                any way to any person, firm or corporation any Confidential
                Information of eSat or its subsidiaries, or of any other party
                to which eSat or its subsidiaries, owes an obligation of
                confidence, and which has not become a part of the public domain
                through no fault of Executive.

        (d)     All notes, reports, studies, data, computer printouts, financial
                information, business plans, analysis, or other documents
                created by or given to Executive during employment concerning or
                related to the eSat Business in all media forms, and whether or
                not containing or relating to Confidential Information, are the
                property of eSat and will be promptly delivered to eSat upon the
                termination of Executive's employment.

        (e)     Executive agrees that, at all times during Executive's
                employment with eSat and for a period of two years thereafter,
                Executive shall not hire any

                                       7.

                employee of eSat or its subsidiaries or to induce any employee
                of eSat or its subsidiaries to terminate his or her employment
                with eSat or its subsidiaries.

        (f)     Executive recognizes and affirms that in the event of breach by
                Executive of any of the provisions of this Section 9, money
                damages would be inadequate and eSat would have no adequate
                remedy at law. Accordingly, Executive agrees that eSat shall
                have the right, in addition to any other rights and remedies
                existing in its favor, to enforce its rights and Executive's
                obligations under this Section 9 not only by an action or
                actions for damages, but also by an action or actions for
                specific performance, injunction and/or other equitable relief
                to enforce or prevent any violations, whether anticipatory,
                continuing or future, of the provisions of this Section 9.

        (g)     If any of the provisions of this Section 9 are determined by
                arbitration or adjudicated to be excessively broad as to: (1)
                geographic area, (2) the nature of the business activity
                involved, (3) duration in time, or (4) any other attribute, the
                parties authorize the court construing the same to modify the
                excessively broad provisions to such limited extent as is
                reasonable, given the original express of intent of the parties,
                and to enforce the restriction as modified or to eliminate the
                restriction if it cannot be reasonably modified. Any provisions
                of this Agreement not so modified or eliminated shall remain in
                full force and effect.

        (h)     Executive agrees that, except as otherwise required by law and
                excluding proceedings under Section 10 hereof in which eSat and
                the Executive are adverse to one another, Executive will not at
                any time without the prior consent of eSat discuss or otherwise
                divulge to any person or entity other than Executive's legal
                counsel any opinion, information, evidence or testimony which
                Executive is to offer in any litigation, arbitration, or other
                adversarial proceeding in which eSat, its interests or the
                interests of its subsidiaries or shareholders are directly or
                indirectly involved. If Executive is contacted by or approached
                by any person or entity to discuss or disclose any such matters,
                Executive will immediately report the occurrence to eSat. If
                Executive is served with legal process of any kind which
                requires Executive to disclose any such matters, Executive will
                immediately report such service to eSat, provide eSat with
                copies of the process, and decline to respond to the process
                until: (1) the last date permitted for response to the process,
                or (2) eSat's counsel shall have determined how to proceed in
                eSat's best interest, whichever event shall first occur. The
                covenants given by Executive under this Section 9 will survive
                the termination of Executive's employment.

        10. Arbitration of Disputes.

        (a)     Arbitration. All Arbitration Claims (defined below) between the
                parties shall be resolved by submission to final and binding
                arbitration under the rules of the American Arbitration
                Association ("AAA"). The parties may agree on a retired judge
                from the AAA panel. If they are unable to agree, AAA will
                provide a list of three available judges and each party shall
                strike one. The remaining judge shall serve as the arbitrator
                for purposes of resolving such dispute. The parties agree that
                arbitration must be initiated within 60 days after a party
                delivers a notice of intention to arbitrate pursuant this
                Section 10.

        (b)     Initiation of Arbitration; Submission Agreement. Any party to
                this Agreement may initiate arbitration of a dispute subject to
                this Paragraph, by sending written notice of an intention to
                arbitrate by registered or certified mail to all other parties
                and to AAA. The notice shall contain a description of the
                Arbitration Claim(s) asserted by the party, the amount involved
                and the remedy sought. In the event a demand for arbitration is
                made by any party to this Agreement, the parties agree to
                execute a Submission Agreement provided by AAA, in a form
                customarily used by AAA, setting forth (i) the rights of the
                parties if the matter is arbitrated and (ii) the rules and
                procedures to be followed at the arbitration hearing.
                Notwithstanding anything to the contrary contained in this
                Agreement, each party shall bear its own legal, consulting and
                expert witness fees in connection with any arbitration
                proceeding under this Section 10.

        (c)     One-Year To Initiate Arbitration Claim. The parties agree that
                arbitration must be initiated within one year after the
                occurrence of the events on which any Arbitration Claim is
                based, and a party's failure to initiate arbitration within such
                one-year period constitutes an absolute bar to the institution
                of any new proceedings.

        (d)     "Arbitration Claim" Defined. For purposes of this Agreement,
                "Arbitration Claims" shall mean any contract, tort, statutory or
                other claim, demand, cause of action or dispute asserted by any
                party to this Agreement against any other party to this
                Agreement, arising out of or related to (i) this Agreement or
                any modification, amendment or supplement thereof, or (ii) the
                employment relationship between the parties.

        (e)     Intent of the Parties - Adequate Consideration. By this
                provision, it is the intent of the parties to establish
                procedures to accomplish the informal and inexpensive resolution
                of any Arbitration Claim between the parties without resort to
                litigation. The parties agree that their mutual, binding
                promises to arbitrate any Arbitration Claim between them
                represent

                                       9.
<PAGE>   10

                valuable and adequate consideration for the enforceability of
                this provision.

        (f)     Attorneys Fees. The prevailing party in any such arbitration
                shall be entitled to recover all costs incurred and reasonable
                attorneys fees from the other party in addition to any other
                relief granted or awarded.

        Either party hereto may designate a different address by providing
written notice of such new address to the other party hereto.

        (b)     Severability. If any provision contained in this Agreement is
                determined by a court of competent jurisdiction to be void,
                illegal or, subject to Section 9(g) hereof, unenforceable, in
                whole or in part, then the other provisions contained herein
                shall remain in full force and effect as if the provision which
                was determined to be void, illegal, or unenforceable had not
                been contained herein.

        (c)     Waiver, Modification, and Integration. The waiver by any party
                hereto of a breach of any provision of this Agreement shall not
                operate or be construed as a waiver of any subsequent breach by
                any party. This instrument contains the entire agreement of the
                parties concerning employment and supersedes all prior and
                contemporaneous representations, understandings and agreements,
                either oral or in writing, between the parties hereto with
                respect to the employment of the Executive by eSat and all such
                prior or contemporaneous representations, understandings and
                agreements, both oral and written, are hereby terminated. This
                Agreement may not be modified, altered or amended except by
                written agreement of all the parties hereto.

        (d)     Binding Effect. This Agreement shall be binding and effective
                upon eSat and its successors and permitted assigns, and upon the
                Executive and the Executive's heirs and representatives;
                provided, however, that eSat shall not assign this Agreement
                without the written consent of the Executive.

        (e)     Governing Law. The parties intend that the laws of the State of
                California should govern the validity of this Agreement, the
                construction of its terms, and the interpretation of the rights
                and duties of the parties hereto.

        (f)     Counterpart Execution. This Agreement may be executed in two or
                more counterparts, each of which shall be deemed an original,
                but all of which together shall constitute but one and the same
                instrument.

        (g)     Entire Agreement. This Agreement contains the entire
                understanding of

                the parties and supersedes any prior written or oral expressions
                of the subject matter hereof.

        (h)     Assignment. This Agreement is not assignable by either party and
                neither party may delegate its duties hereunder without securing
                the prior written consent of the other party; provided, however,
                that eSat may assign this Agreement to a successor entity in the
                course of any transaction or series of related transactions in
                which eSat sells or disposes of its assets or is not a surviving
                entity and a Change in Control occurs, if and only if, the
                successor entity upon consummation of the Change in Control
                transactions assumes eSat's obligations hereunder in writing.

        The parties have executed this Agreement as of the Effective Date.

                              ARTICLE 2. PREMISES

       Landlord hereby leases to Tenant and Tenant hereby leases from Landlord
the Premises as shown on Exhibit A attached hereto, subject to all the terms
and conditions of this Lease.

                                ARTICLE 3. TERM

       The Term of this Lease shall commence on the Scheduled Term Commencement
Date and shall continue until the Expiration Date or earlier termination as
herein provided. Landlord agrees to use due diligence to complete Landlord's
construction obligations as set forth in Section 7.2 and as shown on Exhibit B
attached hereto on or before the Scheduled Term Commencement Date, but in case
of delays due to inclement weather, governmental regulation, scarcity of or
inability to obtain materials, labor difficulties, casualty, acts of God or
other causes beyond Landlord's reasonable control, the Scheduled Term
Commencement Date shall be extended by a period equal to such delays up to 60
days without liability on the part of Landlord and without extending the
Expiration Date. THE PREPAID RENT IN THE AMOUNT OF $11,949.56 SHALL BE APPLIED
TO THE FIRST THIRTY DAYS AFTER ANY SUCH REVISED SCHEDULED TERM COMMENCEMENT
DATE. ANY PARTIAL MONTH SHALL BE PRORATED AS DEFINED IN ARTICLE 4 BELOW.
Landlord's construction obligations are not completed and possession of the
Premises is not given or tendered to Tenant by Landlord on or before the 60th
day following the Scheduled Term Commencement Date, subject to extension as
provided above, Tenant's sole right shall be to terminate this Lease by giving
written notice of termination to Landlord within five (5) days after the end of
such 60-day period, and Landlord shall in no case be liable in any manner for
failure to have the Premises ready for occupancy. Upon such termination, the
parties shall be released from all duties, obligations and liabilities
hereunder, Tenant shall have no further right or interest in respect to the
Premises, and any Security Deposit and Prepaid Rent shall be returned to
Tenant. Tenant's failure to complete construction and installation of any
leasehold improvements and fixtures as described in Section 7.2 or on Exhibit C
attached hereto shall not affect commencement of the Term or Tenant's rent
obligations.

                            ARTICLE 4. MONTHLY RENT

     4.1  On or before the first day of each calendar month during the Term,
Tenant shall pay to Landlord the Monthly Rent, subject to the adjustments set
forth below. Tenant shall pay the Monthly Rent to Landlord in advance, without
deduction or offset and without notice or demand, in lawful money of the United
States of America at Landlord's Address, or at such other place or to such
other person as Landlord may designate from time to time by written notice. If
this Lease commences or ends on a day other than the first day of a calendar
month, then the rental for such partial month will be computed on a daily basis
in an amount equal to one-thirtieth (1/30) of the Monthly Rent for each such
day. In addition to the Monthly Rent, Tenant further agrees to pay to Landlord
with each installment of Monthly Rent any excise, sales or transaction
privilege tax imposed or levied by any government or governmental agency upon
Landlord on account of such rent payment and any other payments made hereunder
by Tenant.

     4.2  If Tenant fails to pay Monthly Rent when due or fails to pay when due
any other amounts of any kind payable by Tenant under this Lease, such unpaid
sum shall bear interest at the Default Interest Rate from the date due to the
date of payment. In addition, if Tenant fails to pay Monthly Rent by the fifth
(5th) day of the month in which such installment is due, the Late Fee shall be
added to the Monthly Rent. Any Late Fee and all such interest shall be payable
together with Monthly Rent. The Default Interest Rate and Late Fee provisions
contained herein are intended to reimburse Landlord for the additional costs
and expenses Landlord will incur by reason of such late payment and are in
addition to and not in lieu of any or all of Landlord's rights and remedies
under Article 23 or other provisions hereof. In addition, in the event Tenant
is late on two occasions within any 12-month period in the payment of Monthly
Rent or other sums due hereunder, at its sole option, upon not less

                                       2

<PAGE>   3
than thirty (30) days prior notice to Tenant, Landlord may require Tenant
promptly to execute and deliver to Landlord any documents, instruments,
authorizations, or certificates required by Landlord to give effect to an
automated debiting system whereby payments by Tenant (as designated from time
to time by Landlord) of whatsoever nature required or contemplated by this
Lease shall be debited monthly or from time to time, as determined by Landlord,
from Tenant's account in a bank or financial institution designated by Tenant
and credited to Landlord's bank account as Landlord shall designate from time
to time. Tenant shall promptly pay all service fees and other charges connected
therewith, including, without limitation, any charges resulting from
insufficient funds in Tenant's bank account or any charges imposed on the
Landlord. In the event that Tenant elects to designate a different bank or
financial institution from which any Monthly Rent, additional rent, or other
charges under the Lease are automatically debited, notification of such change
and the required documents, instruments, authorizations, and certificates must
be received by Landlord no later than thirty (30) days prior to the date such
change is to become effective. Tenant agrees that it shall remain responsible
to Landlord for all payments of Monthly Rent, additional rent, and other
charges pursuant to the Lease, even if Tenant's bank account is incorrectly
debited in any given month. Such Monthly Rent, additional rent, and other
charges shall be immediately payable to Landlord upon written demand. Tenant's
failure properly to designate a bank or financial institution or promptly to
provide appropriate information in accordance with this Section 4.2 shall
constitute a default of this Lease.

                 ARTICLE 5. IMPOSITIONS AND OPERATING EXPENSES

     5.1  Tenant shall pay to Landlord as additional rent Tenant's Percentage
of the sum equal to (i) the amount by which, if any, the Property's operating
expenses exceed the annual operating expense base, plus (ii) the amount by
which, if any, the Property's impositions exceed the annual imposition base.
The term "operating expenses" as used herein shall include (a) all reasonable
and necessary costs and expenses incurred by Landlord for the servicing,
operation, maintenance and repair of the building and related interior and
exterior appurtenances of which the Premises is a part, (b) the costs incurred
in order to achieve a reduction of or to minimize the increase in operating
expenses, including without limitation management fees, (c) capital
expenditures for equipment or systems installed to reduce or minimize increases
in operating expenses, (d) capital expenditures required by any governmental
ordinance or act, (e) depreciation or amortization based on the useful life
expectancy of such equipment or systems or expenditures, and (f) the cost of
contesting the validity or amount of real estate taxes. The term "impositions"
shall include all forms of real property taxes and assessments, license fees
and taxes, commercial rental taxes, levies, charges, penalties and other taxes
and similar impositions imposed upon the Property or Landlord by any city,
county, state or federal government or any school, agricultural, lighting,
drainage or other improvement or special assessment district or similar taxing
authority, or any other imposition which after the date hereof shall be
assessed, levied or imposed or becomes due and payable from, or becomes a lien
on, the Premises, the Property or the facilities and appurtenances used in
connection therewith. "Impositions" shall not include Landlord's federal or
state income, franchise, inheritance or estate taxes or any excise, sales or
privilege tax otherwise payable by Tenant under Section 4.1. By way of
illustration but not limitation, operating expenses shall include the cost or
charges for the following items: Utilities and services not separately metered
or billed to tenants, materials, supplies, equipment and tools, service or
maintenance agreements, management fees and costs, accounting and legal
expenses, insurance premiums (including without limitation premiums for
insurance coverage which Landlord, or any ground lessor or lender with a lien
affecting the Premises, requires or deems desirable), repair, maintenance and
all other costs connected with the parking and other common areas, repair and
maintenance costs incurred by Landlord under Article 8, depreciation on
personal property and extraordinary nonrecurring costs normally capitalized
under recognized accounting principles, which costs shall be included as annual
operating expenses in the amount amortized in each year over the useful life of
such capitalized item.

     5.2  Tenant shall pay the additional rent required by Sections 5.1 upon
demand by Landlord. Landlord shall have the right to demand periodic payments
in advance, with underpayments or overpayments to be adjusted annually or on
such other basis as Landlord may select. Notwithstanding anything to the
contrary herein, no credit or other adjustment for overpayment shall ever be
applicable to reduce Monthly Rent.

<PAGE>   4
                           ARTICLE 6. USE OF PREMISES

     6.1  Tenant shall use the Premises for the Permitted Uses and for no other
purpose. Tenant in its use of the Premises shall not commit, or suffer to be
committed, any nuisance or other act which may disturb the quiet enjoyment of
any other tenant of the Property, and Tenant agrees not to deface or damage the
Premises or any other portion of the Property in any manner or overload the
floors of the Premises. Tenant will not use or permit the use of the Premises or
any part thereof for any purposes that in Landlord's opinion impairs the
reputation of the Property or that is prohibited by law, and Tenant at its sole
expense will comply with and conform to all requirements of all governmental
authorities relating in any way to Tenant's use or occupancy of the Premises.
Tenant shall discontinue and thereafter refrain from making any such use of the
Premises upon Tenant's receipt of written notice from Landlord.

     6.2  No flammable or other hazardous goods, merchandise or materials shall
be kept by Tenant on or about the Premises, and Tenant shall not otherwise
suffer or permit any acts of omission or commission which could increase the
premiums for fire or liability insurance. If the fire or liability insurance
premiums are increased by any such act of Tenant, then the increased premium
cost shall be paid by Tenant to Landlord forthwith upon demand. Tenant, at its
sole expense, shall comply with any and all requirements of any insurance
organization or company necessary for the maintenance of reasonable fire and
public liability insurance covering the Premises and the Property.

                             ARTICLE 7. ALTERATIONS

     7.1  Except as provided in Section 7.2, Tenant will not make or allow to be
made to the Premises any alteration of any kind without the prior written
consent of Landlord. All of Tenant's approved work shall be done by duly
licensed contractors in accordance with all applicable laws, codes, ordinances,
rules and regulations, and Tenant shall obtain at its cost any required permits,
licenses or inspections for performance of its work. If any mechanic's or
materialman's lien at any time, whether before, during or after the Lease term,
shall be filed against any part of the building housing the Premises by reason
of work, labor, services or materials performed for or furnished to Tenant,
Tenant shall forthwith cause the lien to be discharged of record or bonded off
to the satisfaction of Landlord. If Tenant shall fail to cause such lien to be
discharged or bonded off within five (5) days after being notified of the filing
thereof, then, in addition to any other right or remedy of Landlord, Landlord
may discharge the lien by paying the amount claimed to be due. The amount paid
by Landlord, and all costs and expenses, including reasonable attorneys' fees
incurred by Landlord in procuring the discharge of the lien, shall be due and
payable by Tenant to Landlord as additional rent promptly, upon demand.

     7.2  Subject to the terms and conditions herein contained, Tenant shall
have the right, but shall not be obligated to, construct and install at its sole
expense in accordance with generally accepted construction standards and
architectural/engineering plans approved in advance by Landlord (which approval
shall not constitute a warranty that the proposed improvements conform to laws
or applicable building codes) the leasehold improvements and fixtures described
on Exhibit C. Tenant shall be solely responsible for obtaining occupancy permits
and other permits or licenses necessary for its lawful occupancy of the
Premises. Landlord's sole construction obligation is to construct and install,
in accordance with generally accepted construction standards, the walls, doors,
flooring and such finished partitioning, electrical outlets and electrical
fixtures as may be shown on Exhibit B. Tenant shall keep the Premises and the
improvements thereon free and clear of all liens arising out of or claimed by
reason of any work performed, material furnished or obligations incurred by or
at the instance of Tenant, and by its execution hereof Tenant hereby indemnifies
and saves Landlord, the Premises and the Property harmless of all such liens or
claims of lien and all attorneys' fees and other costs and expenses incurred by
reason thereof.

     7.3  All alterations, installations, including without limitation wall to
wall carpet and drapery accessories, changes, replacements, repairs, additions,
or improvements to or within the Premises (whether with or without Landlord's
consent), shall at the election of Landlord remain upon the Premises and be
surrendered with the Premises at the expiration of this Lease without
disturbance, molestation or injury. Should Landlord elect that alterations,
installations, changes, replacements, repairs, additions to or improvements made
by or for Tenant upon the Premises be removed upon termination of this Lease or
upon termination of any renewal period hereof, Tenant hereby agrees that
Landlord shall have the right to cause same to be removed at Tenant's sole cost
and expense. Tenant hereby agrees to reimburse Landlord for the cost of such
removal, together with the cost of repairing

                                       4
<PAGE>   5
any damage resulting therefrom and the cost of restoring the Premises to its
condition at the commencement of the term of this Lease as initially improved by
Landlord. Approximately sixty (60) days prior to Tenant's scheduled exit from
the Premises, Landlord and Tenant shall meet to decide what items shall be
removed and what items shall remain. At such time, Tenant shall deposit with
Landlord an amount equal to the estimated costs of removal and/or restoration of
the Premises, which work shall be performed by or for Landlord at Tenant's
expense.

     7.4  In the event that either Landlord or Tenant shall be required during
the Term, by the order or decree of any court, or any other governmental
authority, or by law, code or ordinance to repair, alter, remove, reconstruct,
or improve any part of the Premises or Property, then Tenant shall make or
Tenant shall permit Landlord to perform such repairs, alterations, removals,
reconstructions or improvements without effect whatsoever to the obligations or
covenants of Tenant herein contained, and Tenant hereby waives all claims for
damages or abatement of Monthly Rent because of such repairing, alteration,
removal, reconstruction, or improvement. Tenant hereby agrees that any
construction upgradings required by any governmental authority as a result of
Tenant's work, either in the Premises or in any other part of the Property, will
be paid for by Tenant.

     7.5  Tenant shall not install any equipment of any kind which will or may
necessitate any changes, replacements or additions to the water system, plumbing
system, heating system, air conditioning system or the electrical system of the
Premises or the building housing same without the prior written consent of the
Landlord. Tenant shall not install or use in the Property any air conditioning
unit, engine, boiler, generator, machinery, heating unit, stove, water cooler
(other than for portable bottled water), ventilator, radiator or any other
similar apparatus without the prior written consent of Landlord, and then only
as Landlord may direct.

     7.6  Landlord shall have the right at any time to alter, repair or improve
the Premises or the Property, and Landlord and its representatives for that
purpose may enter on and about the Premises and the Property with such material
as Landlord may deem necessary, and may erect scaffolding and all other
necessary structures on or about the Premises and the Property. Tenant waives
any claim for damages, including without limitation, loss of business resulting
therefrom. In the exercise of its rights under this Section, Landlord shall use
good faith efforts not unreasonably to interfere with the conduct of Tenant's
business on the Premises.

                             ARTICLE 8. MAINTENANCE

     8.1  Except as provided in Section 8.2 and Article 11, Landlord will
maintain in good condition and repair the structural portions of the building of
which the Premises are a part along with the common areas of same and the
unexposed electrical and plumbing systems and the heating, ventilating and air
conditioning system servicing the Premises; provided, however, the cost of any
maintenance or repairs necessitated by the negligence of Tenant and performed by
Landlord shall be reimbursed directly to Landlord by Tenant promptly upon
demand. Landlord shall have no other duty or obligation to maintain or repair
any portion of the Premises except as expressly provided herein, and such costs
of maintenance and repair shall be part of the expenses for which Tenant shall
reimburse Landlord under Article 5 of this Lease. There shall be no abatement of
or offset in rent, and Landlord will not be liable to Tenant for any damage
resulting from or caused by, Landlord's delay or failure to maintain or make
repairs.

     8.2  Except as provided in Section 8.1 and Article 11, Tenant at its
expense shall maintain in good condition and repair all portions of the
Premises, including without limitation: interior wall surfaces (painting the
same as often as Tenant deems necessary prior to the expiration of the Term)
partitions, floor coverings, and all glass and glazing to the extent same are
damaged or destroyed by Tenant's or its agents' affirmative acts.

                       ARTICLE 9. UTILITIES AND SERVICES

     9.1  Landlord will furnish to the Premises reasonable quantities of
electricity (110 volt), water, heating and cooling (8 A.M. to 6 P.M. Monday
through Friday and 8 A.M. to 12 noon Saturdays, excepting holidays) and
janitorial services (only ordinary dusting and cleaning and not shampooing of
carpets, cleaning draperies or furniture). All of the aforesaid services shall
be provided without cost to Tenant except as such expenses may be included in
calculating the additional rent pursuant to

                                       5

<PAGE>   6
the provisions of Article 5. Landlord shall not be liable for failure to
furnish, or for suspension or delays in furnishing, any of such services caused
by breakdown, maintenance or repair work, strike, riot, civil commotion,
governmental regulations or any other cause or reason whatever beyond the
control of Landlord. Suspension or interruption of services shall not result in
any abatement of rent, be deemed an eviction or relieve Tenant of performance of
Tenant's obligations under this Lease. Should Tenant require heating and cooling
services beyond the hours and/or days stipulated above, upon receipt of at least
72 hours prior written notice from Tenant, Landlord will furnish such additional
services at the then prevailing hourly rates, as established by Landlord from
time to time; provided, further, that there will be a minimum charge of four (4)
hours use each time overtime services are required. Tenant additionally agrees
that Tenant will not install or operate in the Premises any heavy duty
electrical equipment or machinery without first obtaining prior written consent
of Landlord. Landlord may, among other conditions, require as a condition to its
consent for the installation of such equipment or machinery, payment by Tenant
as additional rent for excess consumption of electricity that may be occasioned
by the operation of said equipment or machinery. Landlord may make periodic
inspections of the Premises at reasonable times to determine that Tenant's
electrically operated equipment and machinery complies with the provisions of
this Section. Tenant shall be deemed to consume electricity excessively when (i)
the total average consumption of electricity, including lighting, exceeds five
(5) watts per square foot for the Premises or (ii) when an individual piece of
electrically-operated machinery or equipment has a name plate rating in excess
of two (2) kilowatts. Landlord may require that one or more separate meters be
installed to record the consumption or use of electricity, or shall have the
right to cause a reputable independent electrical engineer to survey and
determine the quantity of electricity consumed by such excessive use. The cost
of any such survey or meters and of installation, maintenance and repair thereof
shall be paid for by Tenant. Tenant agrees to pay Landlord (or the utility
company, if direct service is provided by the utility company), promptly upon
demand, for all such electric consumption and demand as shown by said meters, or
a flat monthly charge determined by the survey, as applicable, at the rates
charged for such service by the local public utility company. If Tenant's cost
of electricity based on meter readings is to be paid to Landlord, Tenant shall
pay a service charge related thereto. Landlord shall not be liable for its
failure to maintain comfortable atmospheric conditions in all or any portion of
the Premises due to heat generated by any equipment, machinery or additional
lighting installed by Tenant (with or without Landlord's consent) that exceeds
design capabilities for the building housing the Premises. If Tenant desires
additional cooling to offset excessive heat generated by such equipment or
machinery, Tenant shall pay for auxiliary cooling equipment and its operating
costs, including without limitation electricity, gas, oil and water, or for
excess electrical consumption by the existing cooling system, as appropriate.

     9.2  Tenant shall timely pay for all water, electricity, telephone, sewage
disposal, refuse collection and other utilities or services separately metered
to the Premises or separately billed to Tenant by the person furnishing the
service. Landlord reserves the right to install separate meters for any utility
serving the Premises for which separate meters are not presently installed, and
Tenant shall pay the cost of such installation for the Premises. Utilities or
services not separately metered or billed (including those described in Section
9.1 above to be furnished by Landlord) shall be part of the operating expenses
described in Article 5.

     9.3  Any security measures Landlord undertakes are for the protection of
the Property only; Tenant acknowledges it does not and shall not rely on such
measures to protect Tenant or its property or employees (or the property of such
employees) at the Premises.

                ARTICLE 10. ACCEPTANCE AND SURRENDER OF PREMISES

     By entry hereunder, Tenant accepts the Premises, including without
limitation, the improvements made therein by Landlord pursuant to Section 7.2,
as being free from defects and in good, clean and sanitary order, condition and
repair, and Tenant agrees to keep the Premises in such condition. On the last
day of the Term, Tenant will surrender the Premises to Landlord in a state of
good repair, subject to Landlord's election in Section 7.1, excepting only
reasonable wear and tear, acts of God and damage by fire or the elements not
caused by Tenant's negligence.

                      ARTICLE 11. DESTRUCTION OF PREMISES

                                       6

<PAGE>   7
     11.1  In the event of partial or total destruction of the Premises during
the Term from any casualty insured against under a standard fire and extended
coverage policy, Landlord shall repair the Premises (subject to the provisions
of Section 11.2) and this Lease shall remain in full force and effect, except
that Tenant shall be entitled to a proportionate reduction of the Monthly Rent
while repairs are being made, such proportionate reduction to be based upon the
extent to which the destruction and the making of repairs interferes with the
business carried on by the Tenant in the Premises. Due allowance, however, shall
be given for reasonable time required for adjustment and settlement of
Landlord's insurance claims, and for such other delays as may result from
government restrictions and controls on construction, if any, and for strikes,
national emergencies and other conditions beyond the control of Landlord.
Restoration by Landlord shall not include replacement of furniture, equipment or
other items that do not become part of the building or any improvements to the
Premises in excess of those provided for as building standard items as of the
commencement of this Lease. Tenant shall be responsible for the repair and
restoration of the Premises and Tenant's property beyond Landlord's obligation
at no cost to Landlord, for which Tenant shall maintain adequate insurance
pursuant to Article 13. In the event of fire or casualty damage to the Premises
caused by the fault or neglect of Tenant, its agents, employees, invitees or
visitors, Landlord shall restore material damage at Tenant's cost and expense.

     11.2  In the event (a) the Premises are partially or totally destroyed by a
cause or casualty not fully covered by standard fire and extended coverage
insurance or (b) the building in which the Premises are situated is damaged or
destroyed by any cause or casualty to the extent of one-third (1/3) or more of
the then replacement cost thereof, or (c) the destruction to either the Premises
or its building occurs during the last twelve (12) months of the Term, or (d)
the holder of a deed of trust entitled to receive casualty insurance proceeds
elects not to permit the insurance proceeds payable upon damage to or
destruction of the Premises to be used for repair, reconstruction or
restoration, or (e) Tenant has vacated or abandoned the Premises, or otherwise
is in default under this Lease (or with the giving of notice or passage of time
or both will be in such default) Landlord may elect to terminate this Lease by
giving notice to Tenant within sixty (60) days after the occurrence of such
damage or destruction. If Landlord does not elect to terminate, then Landlord
shall repair the Premises and this Lease shall remain in full force and effect
except for a proportionate reduction of the Monthly Rent as provided above. No
compensation, or claim, or other diminution of rent will be allowed or paid by
Landlord, by reason of inconvenience, annoyance, or injury to business, arising
from the necessity of repairing the Premises or any portion of the building of
which they are a part.

                           ARTICLE 12. EMINENT DOMAIN

     If any part of the Premises shall be taken by exercise of the right of
eminent domain or transferred by agreement in lieu thereof with or without any
condemnation action or proceeding being instituted, this Lease shall terminate
as of the date title vests in the condemnor or grantee. In the event of any such
taking or transfer of a portion of the Property, but not any part of the
Premises, this Lease shall remain in full force and effect without abatement or
reduction of rent. All compensation or damages awarded upon any taking or
transfer of all or any portion of the Premises or the Property shall belong
totally to Landlord and Tenant shall have no claim thereto, Tenant hereby
assigning any such rights to Landlord. Notwithstanding the foregoing, Tenant
shall have the right to file a separate claim against the condemning authority
for the underdepreciated value of its leasehold improvements and relocation
expenses, provided no such award shall in any way diminish the award payable to
Landlord.

                   ARTICLE 13. INSURANCE; SUBROGATION WAIVER

     13.1  Tenant at its expense will maintain in full force during the Term
public liability and property damage insurance in the amount of the Insurance
Limits insuring against all liability of Tenant arising out of or in connection
with Tenant's use or occupancy of the Premises. Tenant's coverages shall include
business income and extra expense coverage for a minimum of six (6) months. All
public liability insurance and property damage insurance shall insure Tenant's
performance of the indemnity provisions of Section 14.1 below. Tenant will from
time to time, promptly upon request of Landlord furnish to Landlord true and
correct copies of Tenant's policy(ies) and the "additional insured" endorsement,
certified by Tenant as such, evidencing the facts that such insurance has been
obtained and is in full force and effect, that Tenant's insurance is primary to
Landlord's (so that Landlord's coverage is excess) and that Landlord and any
mortgagee or other person as Landlord may

                                       7
<PAGE>   8
designate are additional insureds thereunder, and that such insurance cannot be
canceled without thirty (30) days prior notice to Landlord and any other
additional insureds. Landlord will maintain standard fire and extent coverage
insurance on the building in which the Premises are situated in such amount and
under such terms and conditions as Landlord shall in its sole discretion elect.
Landlord shall have no obligation whatsoever to maintain any other insurance of
any kind, including without limitation, any insurance on property of the Tenant
or Tenant's improvements, and Tenant at its sole cost shall maintain insurance
coverage on its personal property, trade fixtures and improvements in, on or
about the Premises in an amount sufficient so that no co-insurance shall be
payable in the event of a loss.

     13.2  Anything in this Lease to the contrary notwithstanding, Landlord and
Tenant each hereby waives any and all rights of recovery, claim, action or cause
of action against the other for any loss or damage that may occur to the
Premises or any improvements thereto, or any personal property of Landlord or
Tenant, or any injury to persons arising from any cause (whether in tort or not)
that (a) would be insured against under the terms of any insurance required to
be carried hereunder; or (b) is insured against under the terms of any insurance
actually carried, regardless of whether the same is required hereunder. The
foregoing waiver shall apply regardless of the cause or origin of such claim,
including but not limited to the negligence of a party, or such party's agents,
officers, employees or contractors. The foregoing waiver shall not apply if it
would have the effect, but only to the extent of such effect, of invalidating
any insurance coverage of Landlord or Tenant. Each party shall obtain any
special endorsements, if any, required by their respective insurers to evidence
compliance with the aforementioned waiver.

                     ARTICLE 14. EXCULPATION AND INDEMNITY

     14.1  Tenant agrees that Landlord shall not at any time to any extent
whatsoever be liable, responsible or in any way accountable for loss, injury,
death or damage to persons or property on or about the Premises or the Property
from any cause or causes whatsoever, at any time suffered or sustained by Tenant
or any person whomsoever using, occupying or visiting the Premises, and Tenant
by executing this Lease indemnifies and saves Landlord harmless and agrees to
defend Landlord, by and through legal counsel satisfactory to Landlord, from any
and all claims, liabilities, losses, damages, costs and expenses whatsoever
arising out of any such loss, injury, death or damage except if such is a direct
result of the gross negligence or wilful misconduct of Landlord, its agents or
employees. Specifically but not by way of limitation, Landlord shall not be
liable in any manner to Tenant, its agents, employees, invitees or visitors for
any injury or damage to Tenant, Tenant's agents, employees, invitees or
visitors, or their property, caused by the criminal or intentional misconduct of
third parties or of Tenant, Tenant's employees, agents, invitees or visitors.
All claims against Landlord for any such damage or injury are hereby expressly
waived by Tenant, and Tenant hereby agrees to hold harmless and indemnify
Landlord from all such damages and the expense of defending all claims made by
Tenant's employees, agents, invitees, or visitors arising out of such acts.

                   ARTICLE 15. PARKING AND OTHER COMMON AREAS

     15.1  Landlord will keep or cause to be kept all parking and other common
areas (collectively "common areas") of the Property in a neat, clean and orderly
condition, but all costs and expenses thereof shall be charged and pro rated in
the manner hereinabove set forth in Article 5. Nothing herein contained shall be
construed to mean or imply that any portion of the sidewalks, driveways, parking
and common areas are being leased to Tenant, or that Tenant has any easement
rights therein, but it is agreed that Landlord will provide sidewalks,
driveways, parking and common areas, as such may from time to time be designated
and constituted by Landlord in its sole discretion, for use by Tenant in common
with other tenants and their employees and customers.

     15.2  Landlord at all times shall have the right and privilege of
determining the nature and extent of the common areas and of making such changes
therein and thereto from time to time which in Landlord's sole opinion are
desirable and in the best interests of all persons using the common areas,
including without limitation, the location and relocation of driveways,
entrances, exits, parking spaces, landscaped areas and equipment and facilities
on the common areas, the direction and flow of traffic, and the assignment of
parking spaces or areas for the use of particular tenants.

                                       8
<PAGE>   9
     15.3  Nothing contained herein shall be deemed to limit the effect of
Article 14 or to create any liability upon Landlord for any injury to persons or
loss or damage to motor vehicles or the contents thereof of any person using the
common areas unless caused by the gross negligence or wilful misconduct of
Landlord, its agents or employees.

                         ARTICLE 16. ENTRY BY LANDLORD

     Landlord and its representatives shall have the right to enter the Premises
at all reasonable times (a) to inspect the same or to make repairs and to
maintain the building of which the Premises are a part as provided in Section
7.3, (b) to post such reasonable notices as Landlord may desire to protect its
rights, to exhibit the Premises to prospective purchasers or mortgagees of the
Property, (c) during the ninety (90) days prior to the Expiration Date, to
exhibit the Premises to prospective tenants and to place upon the doors or in
the windows of the Premises any usual or ordinary "for rent" or "for lease"
signs, and (d) for any purpose relating to the safety, protection or
preservation of the Property.

                         ARTICLE 17. TENANT'S FIXTURES

     Tenant, at any time Tenant is not in default hereunder, may remove from the
Premises its movable trade fixtures and equipment, and upon expiration or
termination of this Lease, if so requested by Landlord, shall remove all
fixtures and equipment installed on the Premises by Tenant, whether or not such
fixtures and equipment are fastened to the building and regardless of the manner
in which they are so fastened; provided, however, that Tenant shall fully repair
damage of any kind or character occasioned by the removal of any such fixtures
or equipment and shall leave the Premises and building in a good, clean and
sanitary condition at the expiration of the Term.

                     ARTICLE 18. ABANDONMENT OF PERSONALTY

     Tenant shall not vacate or abandon the Premises at any time during the
Term; and, if Tenant shall vacate, abandon or surrender the Premises or be
dispossessed by process of law or otherwise, any personal property left on the
Premises shall at the option of the Landlord be deemed to be abandoned and
belong to Landlord free and clear of any further interest of Tenant;
alternatively, Tenant's property may be disposed of at public or private sale in
accordance with applicable law as Landlord sees fit. The proceeds of any public
or private sale of Tenant's property, or the then current fair market value of
any property retained by Landlord, shall be applied by Landlord against (i) the
expenses of Landlord for removal, storage or sale of the property; (ii) the
arrears of rent or future rent payable under this Lease; and (iii) any other
damages to which Landlord may be entitled hereunder. If Tenant vacates or
abandons the Premises, as defined above, Landlord may, upon presentation of
evidence of a claim valid upon its face of ownership or of a security interest
in any of Tenant's property abandoned in the Premises, turn over such property
to the claimant with no liability to Tenant.

                  ARTICLE 19. TRANSFER OF LANDLORD'S INTEREST

     Landlord reserves the right to sell, assign or transfer all or any part of
the Property and this Lease, and in such event, this Lease will remain in full
force and effect, and Tenant shall continue to perform and abide by all the
terms, covenants and conditions on its part to be performed. Upon any such sale,
assignment or transfer, other than merely as security, Tenant agrees to look
solely to the assignee or transferee with respect to all matters in connection
with this Lease, and the assignor or transferor shall be released from any
further duties, obligations and liabilities hereunder. Landlord may transfer any
Security Deposit to such assignee or transferee, and thereupon Landlord shall be
discharged from any further liabilities in reference thereto.

                     ARTICLE 20. ASSIGNMENT AND SUBLETTING

     20.1  Tenant shall not assign Tenant's rights or delegate Tenant's duties
under this Lease, nor sublet all or any portion of the Premises, nor encumber or
hypothecate the Premises, nor permit the use of all or any part of the Premises
by persons other than Tenant, its employees and agents including by operation of
law (alternatively, a "Transfer"), without the prior written consent of
Landlord, and any such Transfer without such consent shall be void. No Transfer
shall be made except for the entire Premises.

                                       9
<PAGE>   10
     20.2  a.  If the Tenant desires at any time to Transfer the Premises Tenant
shall submit to Landlord at least sixty (60) days before the proposed effective
date of the Transfer ("Proposed Effective Date"), in writing:

          (i)  A request for permission to Transfer, setting forth the Proposed
               Effective Date, which shall be no less than sixty (60) days after
               the sending of that notice;

         (ii)  The name of the proposed subtenant or assignee or other
               transferee;

        (iii)  The nature of the business to be conducted in the Premises after
               the Transfer;

         (iv)  The terms and provisions of the proposed Transfer;

          (v)  A copy of all proposed documentation pertaining to the Transfer;

         (vi)  Current financial statements (audited, if available) of Tenant
               and the proposed transferee; and

        (vii)  Such additional information that Landlord may reasonably request
               to make a reasoned judgment.

           b.  Without in any way limiting Landlord's right to refuse to consent
for any other reason or reasons, Landlord shall be deemed to have reasonably
withheld its consent to any Transfer if, in Landlord's reasonable opinion:

          (i)  The proposed use of the Premises by the transferee is not
               compatible with the operation of the building or the desired
               tenant mix of the building, would entail any but cosmetic
               improvements to the Premises, or would require increased services
               from Landlord;

         (ii)  The financial net worth of a proposed transferee does not meet
               the credit standards applied by Landlord for other tenants under
               leases with comparable terms or the character or business of the
               proposed transferee is inconsistent with the quality of other
               building tenancies;

        (iii)  The proposed transferee is a governmental agency or an
               instrumentality of a governmental agency;

         (iv)  The proposed Transfer would cause a violation of another lease
               for space in the building or would give an occupant of the
               building a right to cancel its lease or abate (or reduce) its
               rent;

          (v)  The proposed transferee's use of the Premises would involve the
               introduction of Hazardous Material to the Premises;

         (vi)  The proposed transferee is a current tenant of the building or an
               entity with whom Landlord is negotiating to lease space in the
               building; or

        (vii)  The Tenant is in default under any of the terms of this Lease as
               of the date Tenant notifies Landlord of the proposed Transfer or
               as of the Proposed Effective Date of the Transfer, or would be in
               default but for the pendency of a grace or cure period.

                                       10
<PAGE>   11
     20.3 Any subletting or assignment consented to by Landlord shall be
evidenced in writing in a form acceptable to Landlord. Consent by Landlord to
any assignment or subletting by Tenant shall not operate as a waiver of the
necessity for obtaining Landlord's consent in writing to any subsequent
assignment or subletting; nor shall the collection or acceptance of rent from
any such assignee, subtenant or occupant constitute a waiver or release of
Tenant of any covenant or obligation contained in this Lease.

     20.4 In the event that Tenant defaults under this Lease in the payment of
rent or additional rent, Tenant hereby assigns to Landlord the rent due from
any subtenant of Tenant and hereby authorizes each such subtenant to pay said
rent directly to Landlord.

     20.5 Within thirty (30) days of receipt of said notice, Landlord shall
have the right to terminate this Lease by giving Tenant not less than thirty
(30) days' notice. If Landlord exercises its right to terminate this Lease,
Tenant agrees that Landlord shall have access to all or a portion of the
Premises thirty (30) days prior to the effective termination date for
remodeling or redecorating purposes. In the event Landlord does not exercise
its right to terminate this Lease, and Landlord has granted its written
consent, Tenant may transfer all, but not a portion of, the Premises.

     20.6 Any rent accruing to Tenant as the result of a sublease which is in
excess of the pro rata share of rent then being paid by Tenant for the portion
of the Premises being sublet, shall be paid by Tenant to Landlord monthly as
additional rent. In the event of any subletting of the Premises or assignment
of this Lease by Tenant, with or without Landlord's consent, Tenant shall
remain liable to Landlord for payment of the rent stipulated herein and all
other covenants and conditions contained herein.

     20.7 Despite the provisions of Section 20.2 (a) and (b), Tenant may assign
this lease or sublet the premises, with notice to Landlord but without the
necessity of Landlord's consent and without creating any election in Landlord
pursuant to Section 20.5, to any corporation which controls, is controlled by,
or is under common control with Tenant, to any corporation resulting from the
merger or consolidation with Tenant, or to any person or entity which acquires
all the assets of Tenant as a going concern of the business being conducted on
the Premises.

                       ARTICLE 21. RULES AND REGULATIONS

     Landlord shall have the right from time to time to establish, alter and
amend rules and regulations, which, in Landlord's judgment, may be necessary or
desirable for the use, entry onto, operation and management of the Premises and
the Property, and Tenant agrees to comply with all such rules and regulations.
The existing rules and regulations are attached hereto as Exhibit D. Nothing
contained in this Lease shall be construed to impose upon Landlord any duty or
obligation to enforce such rules and regulations, or the terms, conditions or
covenants contained in any other lease, as against any other tenant, and
Landlord shall not be liable to Tenant for violation of the same by any other
tenant, its employees, agents, business invitees, licensees, customers,
clients, family members or guests. Further, it shall be Landlord's reasonable
judgment whether Tenant is in compliance with the Rules and Regulations.

                               ARTICLE 22. SIGNS

     Tenant shall not place or permit to be placed any sign, advertisement,
notice or other display on any part of the inside or outside of the Premises,
except of such color, size and style and in such locations as shall be
designated by Landlord. Tenant, upon request of Landlord, shall immediately
remove (and repair any damage caused by removal of) at Tenant's sole expense
any sign, advertisement, notice or other display which Tenant has placed or
permitted to be placed on any part of the inside or outside of the Premises (a)
if, in the opinion of Landlord, it is objectionable, offensive or not in good
taste (and if Tenant shall fail so to do, Landlord may enter the Premises and
remove the same at the expense of Tenant) and (b) at the end of the Term
hereof. Landlord shall have the right to prohibit any advertisement or
publication of Tenant on or off the Premises which in Landlord's opinion tends
to impair the reputation or character of the Property or Landlord. Tenant shall
refrain from and discontinue such advertisement or publication upon receipt of
written notice from Landlord or no later than three (3) days after mailing
thereof.

                                       11
<PAGE>   12
                              ARTICLE 23. DEFAULT

     23.1 If Tenant shall fail to pay any part of the Monthly Rent or additional
rent herein provided, or any other sum required by this Lease to be paid to
Landlord at the time or in the manner provided, and such failure continues for
five (5) days after written notice thereof from Landlord to Tenant, or if (i)
any proceedings under the Bankruptcy Code (or any amendment thereto) are
commenced by or against Tenant, (ii) Tenant is adjudged insolvent or makes an
assignment for the benefit of its creditors, or (iii) a writ of attachment or
execution is levied on the leasehold estate hereby created and is not released
or satisfied within five (5) days thereafter (with the events in (i) through
(iii) above being referred to herein as an "Event of Bankruptcy"), or if a
receiver is appointed in any proceeding or action to which Tenant is a party
with authority to take possession or control of the Premises or the business
conducted thereon by Tenant and such receiver is not discharged within a period
of five (5) days after appointment, or if Tenant shall fail to abide by or
perform any of the other covenants or conditions on Tenant's part agreed to be
observed or performed and such failure continues for thirty (30) days after
written notice thereof from Landlord to Tenant, then Landlord, in addition to
any other rights or remedies Landlord may have whether under this Lease or at
law or in equity, may:

          (a) Terminate Tenant's right to possession of the Premises by any
lawful means, in which case this lease and the term hereof shall terminate and
Tenant shall immediately surrender possession of the Premises to Landlord. In
such event, Landlord shall be entitled to recover from Tenant (i) the worth at
the time of the award of the unpaid rent which had been earned at the time of
termination; (ii) the worth at the time of award of the amount by which the
unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that the Tenant proves could have
been reasonably avoided; (iii) the worth at the time of award of the amount by
which the unpaid rent for the balance of the term after the time of award
exceeds the amount of such rental loss that the Tenant proves could be
reasonably avoided; and (iv) any other amount necessary to compensate Landlord
for all the detriment proximately caused by the Tenant's failure to perform its
obligations under this lease or which in the ordinary course of things would be
likely to result therefrom, including but not limited to the cost of recovering
possession of the Premises, expenses of reletting (including without limitation
brokerage fees and commissions and rent concessions), including necessary
renovation and alteration of the Premises, reasonable attorneys' fees, and that
portion of the leasing commission previously paid by Landlord applicable to the
unexpired term of this lease. The worth at the time of award of the amount
referred to in provision (iii) of the prior sentence shall be computed by
discounting such amount at the discount rate of the Federal Reserve Bank of San
Francisco at the time of award plus one percent. Efforts by Landlord to mitigate
damages caused by Tenant's default or breach of this lease shall not waive
Landlord's right to recover damages under this Paragraph. If termination of this
lease is obtained through the provisional remedy of unlawful detainer, Landlord
shall have the right to recover in such proceeding the unpaid rent and damages
as are recoverable therein, or Landlord may reserve therein the right to recover
all or any part thereof in a separate suit for such rent and/or damages. If a
notice and grace period is required hereunder and was not previously given, a
notice to pay rent or quit, or to perform or quit, as the case may be, given to
Tenant under any statute authorizing the forfeiture of leases for unlawful
detainer shall also constitute the applicable notice for grace period purposes
required.

          (b) re-enter the Premises by summary proceedings or otherwise, with
or without terminating this Lease, remove all persons and property from the
Premises without liability to any person for damages sustained by reason of
such removal and re-let the Premises at such rental and upon such other terms
and conditions as Landlord in its sole discretion may deem advisable. In such
event, unless Landlord elects to terminate this Lease (in which event the
provisions of subparagraph (a) immediately above shall apply) Tenant shall
remain liable for Monthly Rent and Operating Expenses and other amounts payable
by Tenant hereunder as well as the cost of obtaining possession of and
re-letting the Premises and of any repairs and alterations necessary to prepare
the Premises for re-letting, together with interest at the Default Interest
Rate, less the rents received from such re-letting, if any. Any and all monthly
deficiencies so payable by Tenant shall be paid monthly on the date herein
provided for the payment of Monthly Rent. No such re-entry or taking possession
of the Premises by Landlord shall be construed as an election by Landlord to
terminate this Lease or accept a surrender thereof unless a written notice of
such intention, signed by Landlord, is given to Tenant. Notwithstanding any
such re-letting without termination, Landlord may at any time thereafter elect
to terminate this Lease for such previous breach or any other breach; or

                                       12
<PAGE>   13
        (c) Exercise Landlord's remedies under Section 23.2 below, where
applicable.

Should Landlord at any time terminate this Lease for any breach, in addition to
any other remedies Landlord may have, Landlord may recover from Tenant all
damages Landlord may suffer or incur by reason of such breach, including the
cost of recovering the Premises, and including the worth at the time of such
termination of the excess, if any, if the amount of Monthly Rent and other
charges reserved in this Lease for the remainder of the Term over the reasonable
rental value of the Premises for the remainder of the Term, all of which
amounts shall be immediately due and payable from Tenant to Landlord.

     23.2  Upon occurrence of an Event of Bankruptcy, Landlord shall have the
right to terminate this Lease by giving written notice to Tenant; provided,
however, that this Section 23.2 shall have no effect while a case in which
Tenant is the subject debtor under the Bankruptcy Code is pending, unless
Tenant or its Trustee is unable to comply with the provisions below. At all
other times this Lease shall automatically cease and terminate, and Tenant
shall be immediately obligated to quit the Premises upon the giving of notice
pursuant to this Section. Any other notice to quit, or notice of Landlord's
intention to re-enter is hereby expressly waived. If Landlord elects to
terminate this Lease, everything contained in this Lease on the part of
Landlord to be done and performed shall cease without prejudice, subject,
however, to the rights of Landlord to recover from Tenant all rent and any
other sums accrued up to the time of termination or recovery of possession by
Landlord, whichever is later, and any other monetary damages or loss of reserved
rent sustained by Landlord. Upon termination of this Lease pursuant to this
Section 23.2, Landlord may proceed to recover possession under and by virtue of
the provisions of the laws of any applicable jurisdiction, or by such other
proceedings, including re-entry and possession, as may be applicable.

     Without regard to any action by Landlord as authorized by this Section
23.2, Landlord may at its discretion exercise all the additional provisions set
forth above in Section 23.1.

     In the event Tenant becomes the subject debtor in a case pending under the
Bankruptcy Code, Landlord's right to terminate this Lease pursuant to this
Section 23.2 shall be subject to the rights of the Trustee in Bankruptcy to
assume or assign this Lease. The Trustee shall not have the right to assume or
assign this Lease unless the Trustee (x) promptly cures all defaults under this
Lease, (y) promptly compensates Landlord for monetary damages, incurred as a
result of such default, and (z) provides adequate assurance of future
performance on the part of Tenant as debtor in possession or on the part of the
assignee Tenant.

     Landlord and Tenant hereby agree in advance that adequate assurance of
future performance, as used in this Section 23.2, shall mean that all of the
following minimum criteria must be met: (i) Tenant's gross receipts in the
ordinary course of business during the thirty-day period immediately preceding
the initiation of the case under the Bankruptcy Code must be at least two times
greater than the next payment of Monthly Rent due under this Lease; (ii) both
the average and median of Tenant's gross receipts in the ordinary course of
business during the six-month period immediately preceding the initiation of the
case under the Bankruptcy Code must be at least two times greater than the next
payment of Monthly Rent due under this Lease: (iii) Tenant must pay its
estimated pro rata share of the cost of all services provided by Landlord
(whether directly or through agents or contractors and whether or not previously
included as part of the Monthly Rent) in advance of the performance or provision
of such services; (iv) the Trustee must agree that Tenant's business shall be
conducted in a first class manner, and that no liquidating sales, auctions, or
other non-first class business operations shall be conducted on the Premises;
(v) the Trustee must agree that the use of the Premises as stated in this Lease
will remain unchanged and that only the Permitted Uses shall be permitted; and
(vi) the Trustee must agree that the assumption or assignment of this Lease will
not violate or affect the rights of other tenants at the Property. In the event
Tenant is unable to (a) cure its defaults, (b) reimburse the Landlord for its
monetary damages, (c) pay the rent due under this Lease, and all other payments
required of Tenant under this Lease on time (or within five (5) days, or (d)
meet the criteria and obligations imposed by this Section 23.2, Tenant agrees in
advance that it has not met its burden to provide adequate assurance of future
performance, and this Lease may be terminated by Landlord in accordance with
this Section.

     23.3  In addition to the foregoing rights and remedies and so long as this
Lease is not terminated, Landlord shall have the right but not the obligation
to remedy any default of Tenant and

                                       13
<PAGE>   14
Tenant shall pay to Landlord upon demand Landlord's costs in so doing together
with interest thereon from the date of expenditure until the same is repaid at
the Default Interest Rate.

     23.4  All rights and remedies herein conferred upon Landlord shall be
cumulative and not exclusive of any other right or remedy conferred herein or
by law. If Tenant is in default, Landlord may deny Tenant access to the
Premises without terminating this Lease and prevent removal of Tenant's
property from the Premises by any lawful means.

                          ARTICLE 24. ATTORNEYS' FEES

     If either Landlord or Tenant commences, engages in, or threatens to
commence or engage in any legal action or proceeding against the other party
(including, without limitation, litigation or arbitration) arising out of or in
connection with the Lease, the Premises, or the Property (including, without
limitation (a) the enforcement or interpretation of either party's rights or
obligations under this Lease (whether in contract, tort, or both) or (b) the
declaration of any rights or obligations under this Lease), the prevailing
party shall be entitled to recover from the losing party reasonable attorney's
fees, together with any costs and expenses, incurred in any such action or
proceeding, including any attorney's fees, costs and expenses incurred on
collection and on appeal.

                            ARTICLE 25. HOLDING OVER

     25.1  Should Tenant hold possession hereunder after the Expiration Date
without the express written consent of Landlord, Tenant shall be deemed a
tenant at sufferance, permitting Landlord to exercise all or any rights and
remedies available to Landlord hereunder or at law or in equity. Should Tenant
hold possession hereunder after the Expiration Date with the express written
consent of Landlord, Tenant shall be deemed a tenant on a month-to-month basis
upon all the terms, covenants and conditions herein specified unless and only
unless a different basis is expressly set forth in the consent.

     25.2  In the event that Tenant, without the consent of Landlord, shall
hold over the expiration of the Term, then Tenant hereby waives all notice to
quit and agrees to pay to Landlord for the period that Tenant is in possession
after the expiration of this Lease, a monthly rent which is three times the
total rent (Monthly Rent, as stipulated in Section 1.7, plus additional rent)
applicable to the last month of this Lease. Tenant expressly agrees to hold
Landlord harmless from all loss and damages, direct and consequential, which
Landlord may suffer in defense of claims by other parties against Landlord
arising out of the holding over by Tenant, including without limitation
attorneys' fees which may be incurred by Landlord in defense of such claims.
Acceptance of rent by Landlord subsequent to the expiration of the term of this
Lease shall not constitute consent to any holding over. Landlord shall have the
right to apply all payments received after the Expiration Date or any renewal
of this Lease toward payment for use and occupancy of the Premises subsequent to
the expiration of the Term and toward any other sums owed by Tenant to
Landlord. Landlord, at its option, may forthwith re-enter and take possession of
the Premises without process, or by any legal process in force.

              ARTICLE 26. SUBORDINATION AND ESTOPPEL CERTIFICATES

     26.1  This Lease, at the option of Landlord, shall be subject, subordinate
and inferior to the lien and estate of any liens, encumbrances or ground leases
and any renewals, extensions or replacement thereof, now or hereafter affecting
the Premises or the Property. Such subordination shall be effective without any
further act of Tenant, but Tenant agrees to execute, acknowledge and deliver
promptly upon demand such further instrument or instruments subordinating this
Lease to any such liens, encumbrances or ground leases as shall be desired by
Landlord, and hereby agrees that it shall be a material default hereunder
entitling Landlord to exercise its remedies pursuant to Section 23.1,
notwithstanding anything to the contrary in this Lease, if Tenant fails to do
so within ten (10) days after written request by Landlord. Notwithstanding the
foregoing any mortgage holder may at any time subordinate its mortgage to this
Lease without Tenant's consent by notice in writing to Tenant, and thereupon
this Lease shall be deemed prior to such mortgage without regard to their
respective dates of execution, delivery or recording and in that event such
mortgagee shall have the same rights with respect to this Lease as though the
Lease had been executed prior to the execution, delivery and recording of such
mortgage and had been assigned to such mortgagee. Tenant agrees that neither
any foreclosure of any such mortgage nor the institution of any such action or
proceeding

                                       14
<PAGE>   15
against Landlord, or any foreclosure or dispossession proceeding brought by the
holder of any such mortgage to recover possession of the Premises, building
and/or Property, shall by operation of law or otherwise except at the express
election of the holder result in the cancellation or termination of this Lease
or the obligations of Tenant hereunder and upon the request of any such holder
of any such mortgage Tenant covenants and agrees to execute an instrument in
writing satisfactory to such party or parties, or to the purchaser of the
mortgaged premises in foreclosure, whereby Tenant attorns to such successor in
interest.

     26.2      Tenant agrees from time to time within ten (10) days of receipt
of written request by Landlord, to execute, acknowledge and deliver to Landlord
a statement in writing certifying (a) that this Lease is unmodified and in full
force and effect, or if there have been any modifications, that the Lease is in
full force and effect as modified and stating the modifications, (b) that
Tenant has no defenses, offsets or counterclaims against its obligations to pay
Monthly Rent and other monies hereunder and to perform its other covenants
under this Lease, or if there are any defenses, offsets or counterclaims,
setting forth the same in reasonable detail, (c) the current amount of Monthly
Rent, (d) the dates to which the Monthly Rent has been paid and the amount of
any prepaid rent and Security Deposit, (e) the commencement and expiration
dates of the Term, and (f) such other matters as to which certification
reasonably is sought. Tenant hereby agrees that it shall be a material default
hereunder entitling Landlord to exercise its remedies pursuant to Section 23.1
hereof, notwithstanding anything to the contrary in this Lease, if Tenant fails
to do so within ten (10) days after written request by Landlord. Any such
statement delivered pursuant to this Section may be relied upon by any
prospective purchaser, ground lessor, mortgagor or other encumbrance of the
Premises or any prospective assignee of any mortgage, ground lease or
encumbrance upon the Premises.

                      ARTICLE 27. SUBSTITUTION OF PREMISES

     If the Premises contain less than two thousand (2,000) square feet,
Landlord reserves the right, on thirty (30) days written notice to Tenant, to
substitute other space within the Property for the Premises as though such
substitute space was originally leased to Tenant at the time of execution and
delivery of this Lease; provided, however, that the substituted premises shall
contain not less than the square footage of the Premises and there will be no
increase in rental by reason of the substitution. Landlord agrees to pay all
reasonable moving expenses of Tenant incidental to such substitution of
premises.

                              ARTICLE 28. NOTICES

     All notices or demands to be given, made or sent hereunder by either party
