                        1(a)(iii) hereof that ultimately results in such an
                        Event, or a tender or exchange offer or proxy contest is
                        commenced which ultimately results in an Event described

                        demonstrates that such event (x) was requested by a
                        party other than the Board of Directors of the Company
                        that had previously taken other steps reasonably
                        calculated to result in an Event described in Section
                        1(a)(i), 1(a)(ii), 1(a)(iii) or 1(a)(iv) hereof and
                        which ultimately results in an Event described in

                        1(a)(ii), 1(a)(iii) or 1(a)(iv) hereof that ultimately
                        occurs.

        Notwithstanding anything stated in this Section 1(a), an Event shall not
        be deemed to occur with respect to Executive if (x) the acquisition or

        acting in concert, that includes Executive.

               (b) For purposes of this Agreement, a "subsidiary" of the Company
        shall mean any entity of which securities or other ownership interests

of this Agreement, then the Executive shall be entitled to receive from the
Company or its successor (which term as used herein shall include any person

        of the First Event and prior to the end of the Transition Period, the
        employment of Executive with the Company is voluntarily or involuntarily
        terminated for any reason (unless such termination is a voluntary
        termination by Executive other than for Good Reason, is on account of
        the death or Disability of the Executive or is a termination by the
        Company for Cause), subject to the limitations set forth in Sections
        2(d) and 2(e), Executive shall be entitled to the following:

                        (i)     The Company shall pay Executive's full base
                                salary through the Termination Date at the rate
                                then in effect.

                        (ii)    The Company or its successor, within 90 days
                                after the Termination Date, shall make a cash
                                payment to Executive in an amount equal to one
                                (1) times the sum of (A) the annual base salary
                                of Executive in effect immediately prior to the
                                First Event plus (B) the cash bonus or cash

                        (iii)   For a 12-month period after the Termination
                                Date, the Company shall allow Executive to

                                insurance plan or program in which the Executive
                                was entitled to participate immediately prior to
                                the First Event as if Executive were an employee
                                of the Company during such 12-month period;
                                provided, however, that in the event that
                                Executive's participation in any such health,
                                disability or life insurance plan or program of

                                Executive with benefits substantially similar to
                                those which Executive would be entitled to
                                receive under such plan or program if Executive
                                were not barred from participation. Benefits
                                otherwise receivable by Executive pursuant to
                                this section 2(a)(iii) shall be reduced to the
                                extent comparable benefits are received by
                                Executive from another employer or other third
                                party during such 12-month period, and Executive
                                shall promptly report receipt of any such
                                benefits to the Company.

                        (iv)    Any outstanding and unvested stock options
                                granted to Executive shall be accelerated and
                                become immediately exercisable by Executive (and
                                shall remain exercisable for the terms specified
                                in the applicable stock option agreements) and
                                any restricted stock awarded

                                to Executive and subject to forfeiture shall be
                                fully vested and shall no longer be subject to
                                forfeiture.

                (b)     The Company shall also pay to Executive all legal fees
        and expenses incurred by the Executive as a result of such termination,
        including, but not limited to, all such fees and expenses, if any,
        incurred in contesting or disputing any such termination or in seeking
        to obtain or enforce any right or benefit provided by this Agreement.

                (c)     In addition to all other amounts payable to Executive
        under this Section 2, Executive shall be entitled to receive all
        benefits payable to Executive under any other plan or agreement relating
        to retirement benefits.

                (d)     Executive shall not be required to mitigate the amount
        of any payment or other benefit provided for in Section 2 by seeking
        other employment or otherwise, nor shall the amount of any payment or
        other benefit provided for in Section 2 be reduced by any compensation
        earned by Executive as the result of employment by another employer
        after the Termination Date or otherwise, except as specifically provided
        in this Agreement.

                (e)     Notwithstanding any other provision of this Agreement,
        the Company will not pay to Executive, and Executive will not be
        entitled to receive, any payment pursuant to Section 2(a)(ii) unless and
        until:

                        (i)     Executive executes, and there shall be effective
                                following any statutory period for revocation or
                                rescission, a release that irrevocably and
                                unconditionally releases the Company, any
                                company acquiring the Company or its assets, and
                                their past and current shareholders, directors,
                                officers, employees and agents from and against
                                any and all claims, liabilities, obligations,
                                covenants, rights and damages of any nature
                                whatsoever, whether known or unknown,
                                anticipated or unanticipated; provided, however,
                                that the release shall not adversely affect
                                Executive's rights to receive benefits to which
                                he is entitled under this Agreement or
                                Executive's rights to indemnification under
                                applicable law, the charter documents of the
                                Company, any insurance policy maintained by the
                                Company or any written agreement between the
                                Company and Executive; and

                        ii)     Executive executes an agreement prohibiting
                                Executive for a period of one (1) year following
                                the Termination Date from soliciting, recruiting
                                or inducing, or attempting to solicit, recruit
                                or induce, any employee of the Company or of any
                                company acquiring the Company or its assets to
                                terminate the employee's employment.

                (f)     The obligations of the Company under this Section 2
        shall survive the termination of this Agreement.

        3.      CERTAIN REDUCTION OF PAYMENTS BY THE COMPANY.

                (a)     Notwithstanding anything contained herein to the
        contrary, prior to the payment of any amounts pursuant to Section 2(a)
        hereof, an independent national accounting firm designated by the
        Company (the "Accounting Firm") shall compute whether there would be any
        "excess parachute payments" payable to Executive, within the meaning of
        Section 280G of the Internal Revenue Code of 1986, as amended (the
        "Code"), taking into account the total "parachute payments," within the
        meaning of Section 280G of the Code, payable to Executive by the Company
        or any successor thereto under this Agreement and any other plan,
        agreement or otherwise. If there would be any excess parachute payments,
        the Accounting Firm will compute the net after-tax proceeds to
        Executive, taking into account the excise tax imposed by Section 4999 of
        the Code, if (i) the payments hereunder were reduced, but not below
        zero, such that the total parachute payments payable to Executive would
        not exceed three (3) times the "base amount" as defined in Section 280G
        of the Code, less One Dollar ($1.00), or (ii) the payments hereunder
        were not reduced. If reducing the payments hereunder would result in a
        greater after-tax amount to Executive, such lesser amount shall be paid
        to Executive. If not reducing the payments hereunder would result in a
        greater after-tax amount to Executive, such payments shall not be
        reduced. The determination by the Accounting Firm shall be binding upon
        the Company and Executive subject to the application of Section 3(b)
        hereof.

                (b)     As a result of uncertainty in the application of
        Sections 280G of the Code, it is possible that excess parachute payments
        will be paid when such payment would result in a lesser after-tax amount
        to Executive; this is not the intent hereof. In such cases, the payment
        of any excess parachute payments will be void ab initio as regards any
        such excess. Any excess will be treated as an overpayment by the Company
        to Executive. Executive will return the overpayment to the Company,
        within fifteen (15) business days of any determination by the Accounting
        Firm that excess parachute payments have been paid when not so intended,
        with interest at an annual rate equal to the rate provided in Section
        1274(d) of the Code (or 120% of such rate if the Accounting Firm
        determines that such rate is necessary to avoid an excise tax under
        Section 4999 of the Code) from the date Executive received the excess
        until it is repaid to the Company.

                (c)     All fees, costs and expenses (including, but not limited
        to, the cost of retaining experts) of the Accounting Firm shall be borne
        by the Company and the Company shall pay such fees, costs, and expenses
        as they become due. In performing the computations required hereunder,
        the Accounting Firm shall assume that taxes will be paid for state and
        federal purposes at the highest possible marginal tax rates which could
        be applicable to Executive in the year of receipt of the payments,
        unless Executive agrees otherwise.

        4.      DEFINITION OF CERTAIN ADDITIONAL TERMS.

                (a)     "Cause" shall mean, and be limited to, (i) willful and
        gross neglect of duties by the Executive or (ii) an act or acts
        committed by the Executive constituting a felony and substantially
        detrimental to the Company or its reputation.

                (b)     "Disability" shall mean Executive's absence from his
        duties with the Company on a full time basis for 180 consecutive
        business days, as a result of Executive's incapacity due to physical or
        mental illness, unless within 30 days after written notice of intent to
        terminate is given by the Company following such absence Executive shall
        have returned to the full time performance of Executive's duties.

                (c)     "Good Reason" shall mean if, without Executive's express
        written consent, any of the following shall occur:

                        (i)     the assignment to Executive of any material
                                duties inconsistent with Executive's status or
                                position with the Company, or any other action
                                by the Company that results in a substantial
                                diminution in such status or position, excluding
                                any isolated, insubstantial, or inadvertent
                                action not taken in bad faith and which is
                                remedied by the Company promptly after receipt
                                of notice thereof from Executive;
                                notwithstanding the foregoing, a change in title
                                and/or reporting relationship alone shall not
                                constitute a substantial diminution in an
                                Executive's status or position.

                        (ii)    a material reduction by the Company in
                                Executive's annual base salary or target
                                incentive in effect immediately prior to the
                                First Event;

                        (iii)   the failure by the Company to continue to
                                provide Executive with benefits at least as
                                favorable in the aggregate to those enjoyed by
                                Executive under the Company's pension, life
                                insurance, medical, health and accident,
                                disability, deferred compensation, incentive
                                awards, employee stock options or savings plans
                                in which Executive was participating at the time
                                of the First Event, the taking of any action by
                                the Company that would directly or indirectly
                                materially reduce any of such benefits or
                                deprive Executive of any material fringe benefit
                                enjoyed at the time of the First Event, or the
                                failure by the Company to provide Executive with
                                the number of paid vacation days to which
                                Executive is entitled at the time of the First
                                Event, but excluding any failure or action by
                                the Company that is not taken in bad faith and
                                which is remedied by the Company promptly after
                                receipt of notice thereof from Executive; or

                                any place other than a location within forty
                                miles of the location at which Executive
                                performed his primary duties immediately prior
                                to the First Event or, if Executive is based at
                                the Company's principal executive offices, the
                                relocation of the Company's principal executive
                                offices to a location more than forty miles from
                                its location immediately prior to the First
                                Event, except for required travel on the
                                Company's business to an extent substantially
                                consistent with Executive's prior business
                                travel obligations;

                        (v)     the failure of the Company to obtain agreement
                                from any successor to assume and agree to
                                perform this Agreement, as contemplated in
                                Section 5(b).

                (d)     As used herein, other than in Section 1(a) hereof, the
        term "person" shall mean an individual, partnership, corporation,
        estate, trust or other entity.

                (e)     "Termination Date" shall mean the date of termination of
        Executive's employment, which in the case of termination for Disability
        shall be the 30th day after notice is given as required in Section 4(b).

                (f)     "Transition Period" shall mean the one-year period
        commencing on the date of the earliest to occur of an Event described in
        Section 1(a)(i), 1(a)(ii), 1(a)(iii) or 1(a)(iv) hereof (the
        "Commencement Date") and ending on the first anniversary of the
        Commencement Date.

        5.      SUCCESSORS AND ASSIGNS.

                (a)     This Agreement shall be binding upon and inure to the
        benefit of the successors, legal representatives and assigns of the
        parties hereto; provided, however, that the Executive shall not have any
        right to assign, pledge or otherwise dispose of or transfer any interest
        in this Agreement or any payments hereunder, whether directly or
        indirectly or in whole or in part, without the written consent of the
        Company or its successor.

                (b)     The Company will require any successor (whether direct
        or indirect, by purchase of a majority of the outstanding voting stock
        of the Company or all or substantially all of the assets of the Company,
        or by merger, consolidation or otherwise), by agreement in form and
        substance satisfactory to Executive, to assume expressly and agree to
        perform this Agreement in the same manner and to the same extent that
        the Company would be required to perform it if no such succession had
        taken place. Failure of the Company to obtain such agreement prior to
        the effectiveness of any such succession (other than in the case of a
        merger or consolidation) shall be a breach of this Agreement and shall
        entitle Executive to compensation from the Company in the same amount
        and on the same terms as Executive

                                      -9-

<PAGE>
        would be entitled hereunder in the event of termination by Executive for
        Good Reason, except that for purposes of implementing the foregoing, the
        date on which any such succession becomes effective shall be deemed the
        Termination Date. As used in this Agreement, "Company" shall mean the
        Company as hereinbefore defined and any successor to its business and/or
        assets as aforesaid that is required to execute and deliver the
        agreement as provided for in this Section 5(b) or that otherwise becomes
        bound by all the terms and provisions of this Agreement by operation of
        law.

        6.      GOVERNING LAW. This Agreement shall be construed in accordance
with the laws of the State of Minnesota.

        7.      NOTICES. All notices, requests and demands given to or made
pursuant to this Agreement shall be in writing and shall be deemed to have been
duly given when delivered or mailed by United States registered or certified
mail, return receipt requested, postage pre-paid, addressed to the last known
residence address of Executive or in the case of the Company, to its principal
executive office to the attention of each of the then directors of the Company
with a copy to its Secretary, or to such other address as either party may have
furnished to the other in writing in accordance herewith, except that notice of
change of address shall be effective only upon receipt.

        8.      REMEDIES AND CLAIM PROCESS. If Executive disputes any
determination made by the Company regarding Executive's eligibility for any
benefits under this Agreement, the amount or terms of payment of any benefits
under this Agreement, or the Company's application of any provision of this
Agreement, then Executive shall, before pursuing any other remedies that may be
available to Executive, seek to resolve such dispute by submitting a written
claim notice to the Company. The notice by Executive shall explain the specific
reasons for Executive's claim and basis therefor. The Board of Directors shall
review such claim and the Company will notify Executive in writing of its
response within 60 days of the date on which Executive's notice of claim was
given. The notice responding to Executive's claim will explain the specific
reasons for the decision. Executive shall submit a written claim hereunder
before pursuing any other process for resolution of such claim. This Section 8
does not otherwise affect any rights that Executive or the Company may have in
law or equity to seek any right or benefit under this Agreement.

        9.      SEVERABILITY. In the event that any portion of this Agreement is
held to be invalid or unenforceable for any reason, it is hereby agreed that
such invalidity or unenforceability shall not affect the other portions of this
Agreement and that the remaining covenants, terms and conditions or portions
hereof shall remain in full force and effect.

        10.     INTEGRATION. The benefits provided to Executive under this
Agreement shall be in lieu of any other severance pay or benefits available to
Executive under any other agreement, plan or program of the Company. In the
event that any payments or benefits become payable to Executive pursuant to
Section 2 of this Agreement, then this Agreement will supersede and replace any
other agreement, plan or program applicable to Executive to the extent that such
other

                                      -10-

<PAGE>
agreement, plan or program provides for payments or benefits to Executive
arising out of the involuntary termination of Executive's employment or
termination by Executive for Good Reason. In addition, the acceleration of stock
options and lapsing of forfeiture provisions of restricted stock provided
pursuant to Section 2(a)(iv) of this Agreement shall not be subject to the
provisions of Article 13 of the Company's 1992 Long-Term Incentive Plan (or
similar successor provision or plan).

        11.     MISCELLANEOUS. No provision of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing and signed by the parties. No waiver by either party hereto at any
time of any breach by the other party to this Agreement of, or compliance with,
any condition or provision of this Agreement to be performed by such other party
shall be deemed a waiver of similar or dissimilar provisions or conditions at
the same or at any prior to similar time.

        12.     TERM. This Agreement shall commence on the date of this
Agreement and shall terminate, and the Term of this Agreement shall end, on the
later of (A) December 31, 2007, provided that such period shall be automatically
extended for one year and from year to year thereafter until notice of
termination is given by the Company or Executive to the other party hereto at
least 60 days prior to December 31, 2007 or the one-year extension period then
in effect, as the case may be, or (B) if the Commencement Date occurs on or
prior to December 31, 2007 (or prior to the end of the extension year then in
effect as provided for in clause (A) hereof), the first anniversary of the
Commencement Date.

        IN WITNESS WHEREOF, the parties hereto have executed this Agreement as

                Premises in its then "AS IS" condition upon Substantial

                       FIRST AMENDMENT TO OFFICE BUILDING
                                      LEASE
                             between PACCOR PARTNERS
                                  and HNC, INC.

        This First Amendment To Office Building Lease between PacCor Partners
and HNC, Inc. ("First Amendment"), is made and entered into effective February
1, 1994 between PACCOR PARTNERS, a California general partnership
("Landlord") and HNC, INC., a California corporation ("Tenant"), with
regard to the following:

A.  Landlord and Tenant entered into an Office Building Lease dated December 1,
    1993 ("Lease").

B.  The Work Letter (Exhibit "C" of the Lease) names Roel Construction Company,
    Inc. ("Roel") as the general contractor.

C.  Tenant has requested to substitute Bycor General Contractors, Inc., a
    California corporation ("Bycor"), for Roel as the general contractor to
    complete the Work on the Premises.

D.  Changing general contractors may delay Substantial Completion (defined in
    Paragraph 5.1 of the Lease) and/or create a claim for damages by Roel.
    Tenant desires to assume both of the aforementioned liabilities and
    indemnify and defend Landlord from any such claim(s).

E.  Landlord and Tenant desire to amend the Lease as set forth in this First
    Amendment.

    NOW, THEREFORE, for valuable consideration the receipt and sufficiency of
which are hereby acknowledged, the parties agree to amend the Lease as follows:

1.  The Lease and Work Letter are hereby amended to replace Roel with Bycor as
    the general contractor. Wherever the term "Roel" appears in the Work Letter
    or Lease, it shall be substituted by "Bycor".

2.  Landlord and Tenant agree that the change of general contractor from Roel to
    Bycor shall be considered Tenant's delay of the Schedule by seven (7) days
    for purposes of paragraph 1.4 of the Lease.

3.  Tenant agrees to indemnify and defend Landlord for all claims directly or
    indirectly arising from this substitution of general contractors,
    specifically, any claim Roel may have for it not being retained as the
    general contractor. Tenant shall not indemnify and defend Landlord for any
    claims directly or indirectly arising from Landlord's sole negligence.
    Landlord shall use reasonable efforts to resolve any claim Roel may have at
    no cost to Landlord or Tenant.

4.  Except as specifically set forth in this First Amendment, all other terms
    and conditions of the Lease, as amended, shall remain in full force and
    effect.

"Expiration Date" shall mean the last day of the initial Term of this Lease. The
Commencement Date and Expiration Date shall be confirmed in writing by Landlord
and Tenant within fifteen (15) days after the Commencement Date.

        3.2 OPTION TO EXTEND TERM:

            (a) Option to Extend Term: As a material part of the consideration
for the execution of this Lease by Tenant, Tenant is hereby granted an option to
extend the Term for the Premises for one (1) five (5) year period ("Extended
Term") following the Expiration Date, by giving Landlord written notice
of Tenant's exercise of the option ("Option Notice") at least six (6) months
before the Expiration Date. If the option to extend is exercised, the "Option
Commencement Date" shall be one day after the Expiration Date and the term of
this Lease shall be extended to the fifth anniversary of the Expiration Date
("Option Expiration Date").

            (b) Provisions Applicable to the Option: The option to extend the
Term of this Lease set forth in the preceding Section may be exercised by Tenant
provided that, at the time Landlord receives the Option Notice, Tenant is not in
material default under this Lease. Notwithstanding Section 3.2(a), if Tenant is
in material default of this Lease on the date Landlord receives the Option
Notice, the Option Notice shall be void and the Extended Term shall not commence
unless Landlord notifies the Tenant in writing within ten (10) days after
receipt of the Option Notice that the Option Notice is accepted and will operate
to extend the Term of this Lease as provided in this Section 3.2. If Tenant is
in material default under this Lease on the date the Extended Term is to
commence and Tenant has not commenced any cure of such default within the cure
periods set forth in Section 12 below, then, in Landlord's sole election, the
Extended Term shall not commence and this Lease shall expire upon the Expiration
Date.

<PAGE>

Notwithstanding any provision to the contrary in this Lease, Tenant shall in no
event be deemed in material default of this Lease if curative action has
occurred pursuant to Section 12.

            (c) Provisions Applicable To The Extended Term: The Extended Term
shall be upon the same terms and conditions as set forth in this Lease except as
follows:

              (i) The Base Rent for the Extended Term shall be adjusted to
ninety-five percent (95%) of the then fair market rental value as more
specifically set forth in Sections 4.3 and 4.4.

              (ii) Tenant will have no option to extend the Term of this Lease
beyond the Option Expiration Date unless the parties agree so in writing.

              (iii) Tenant shall accept the Premises in its then "AS IS"
condition at the Option Commencement Date.

              (iv) If the Lease is extended, then "Term" as used in this Lease
shall include the Term and the Extended Term unless specifically provided to the
contrary in this Lease.

              (v) Landlord shall deliver to Tenant an amendment to this Lease
which shall include the Base Rent for the Extended Term as set forth in Section
4.3. Base Rent for the Extended Term shall be as set forth in Sections 4.3 and

the Base Rent for the Extended Term, provided, however, that the execution of
such amendment shall not be a condition precedent to Tenant's obligation to pay
Base Rent as set forth in Sections 4.3 and 4.4 of this Lease. If the parties do
not agree on the Base Rent for the Extended Term, it shall be determined in
accordance with Section 4.3 of this Lease.

the Term pursuant to Section 3.2, Landlord shall provide Tenant an allowance of
not to exceed One Hundred Fourteen Thousand Six Hundred Eighty and no/100

addition to the Tenant Improvement Allowance and shall be a reimbursement to
Tenant within ten (10) days of Tenant's completing the refurbishments and
actually incurring expenses for such refurbishment of the Premises and
submitting invoices to Landlord indicating the work completed. Refurbishment
and/or alterations shall be in accordance with Section 7.9 of this Lease.

        3.3 CANCELLATION OF LEASE: Tenant shall have the right to cancel this

            (c) "Common Area" (as shown on Exhibit "B") shall mean all areas and
facilities within the Project designated from time to time by Landlord for the
general use and convenience of Tenant and other users of the Project. Common
Area includes, without limitation, walkways, parking lots (as designated by
landlord for non-exclusive tenant parking), landscape areas, sidewalks, and all
other areas of the Project intended for use by Tenant in common with the Project
tenants, their authorized representatives and invitees. Tenant has the
non-exclusive right to use the Common Area along with others so entitled,
subject to rules and regulations promulgated from time to time by Landlord.

            (d) "Common Area Operating Expenses" shall mean all costs and
expenses paid or incurred by Landlord or on Landlord's behalf with respect to
the maintenance and operation of the Common Area and which include but are not
limited to the categories listed in the definition of Building Operating

Building Operating Expenses or (ii) any expense attributable to the maintenance
and/or operation of any interior portion of any building except Building.

            (e) "Lease Expenses" shall mean the sum of (i) Tenant's
proportionate share of Building Operating Expenses which is fifty-two and
3/10ths percent (52.3%) (defined as Rentable Square Footage of 25,259 divided by
48,327 rentable square feet of the Building), and (ii) Tenant's proportionate
share of Common Area Operating Expenses which is twenty-six percent (26%)

Project Rentable Area of 97,311 rentable square feet).

            (f) "Lease Year" shall mean each twelve (12) month period during
the Term after the Base Year.

            (g) "Project Rentable Area" shall mean 97,311 rentable square feet.

            (h) "Real Property Taxes" shall mean all real property taxes and
general and special assessments levied or assessed against real property of the
Premises, including without limitation any tax, fee or excise on (i) rents, (ii)
the square footage, (iii) the act of entering into this Lease, or (iv) the
occupancy of Tenant, or any other tax, or excise, however described including
without limitation value-added tax, levied or assessed by the United States, the
State of California or any political subdivision of the State of California,
including without limitation any county, city and county, public corporation,
district, or any other political entity or public corporation of the State of

                                    Page 15
<PAGE>

California as a direct substitution in whole or in part for, or in addition to,
any real property taxes or general or special assessments. Notwithstanding
anything to the contrary in the preceding sentence, "Real Property Taxes" shall
not mean any municipal, county, state, or federal income, excise, franchise,
estate, succession, inheritance or transfer taxes of Landlord. If any Real
Property Taxes are assessed or collected on the basis of a fiscal period, a
portion of which occurs during the Term and the remainder of which occurs before
or after the Term, then the Real Property Taxes payable for such fiscal period
shall be apportioned between such periods based upon the number of days during
such fiscal period that occur during the Term and the number of days that occur
before or after the Term. Real Property Taxes shall also not include, so long as
Proposition 13 remains in effect in California, any increase in taxes
attributable to any sale or transfer of or change of ownership in the Project
(or any part thereof) which occurs during the initial five (5) years of the
Term. If Real Property Taxes are assessed in combination with the Adjacent
Building, then (for purposes of determining Building Operating Expenses and
Common Area Operating Expenses) the Real Property Taxes shall be allocated on
the basis of the ratio of the Rentable Square Footage to the Project Rentable
Area.

        6.2 ADJUSTMENTS TO COMMON AREA OPERATING EXPENSES: Common Area Operating
Expenses during the Term (including the Base Year) shall be "grossed up" ("Gross
Up") if the Project is less than ninety-five percent (95%) leased and occupied,
in accordance with reasonable and generally accepted accounting principles
consistently applied to reflect what Common Area Operating Expenses would have
been had the Project been ninety-five percent (95%) leased and occupied and
fully assessed for tax purposes as leased and occupied buildings provided that
in no event shall the Gross Up result in Landlord receiving payment or
reimbursement from Tenant for costs or expenses not actually incurred by
Landlord.

        6.3 RENT ADJUSTMENT: If Lease Expenses for any Lease Year are greater
than Lease Expenses for the Base Year (after the Gross Up of Common Area
Operating Expenses), Tenant shall pay such increase in Lease Expenses pursuant
to this Section 6.3 beginning not earlier than the first Lease Year after the
Base Year. Landlord shall deliver to Tenant, at least thirty (30) days prior to
the commencement of each subsequent Lease Year during the Term, a written
statement ("Estimated Statement") setting forth Landlord's estimate of the
amount by which the Lease Expenses for the upcoming Lease Year will be greater
or less than the Lease Expenses for the Base Year (the "Lease Expenses
Difference"). If the Lease Expenses for the upcoming Lease Year ("Next Year")
are estimated to be greater than the Lease Expenses for the Base Year, then
Tenant shall pay to Landlord, on the first day of each month of the Next Year
during the Term, an amount ("Monthly Payment") equal to one-twelfth (1/12th) of
the Lease Expenses Difference, as estimated by Landlord in the most recently
delivered Estimated Statement. Landlord may, at its election, no more than one
(1) time during any Lease Year, deliver to Tenant a revised Estimated Statement,
revising Landlord's estimate of the Lease Expenses, in accordance with
Landlord's most current estimate. No later than one hundred twenty (120) days
after the end of

                                    Page 16
<PAGE>

each Lease Year, Landlord shall deliver to Tenant a written statement ("Actual
Statement") setting forth the actual Lease Expenses Difference allocable to such
Lease Year. If the sum of Monthly Payments actually paid by Tenant during any
Lease Year exceeds the actual Lease Expenses Difference allocable to such Lease
Year, then such excess shall be refunded to Tenant within thirty (30) days after
delivery of the Actual Statement to Tenant. If Tenant has made Monthly Payments
and the sum of Monthly Payments actually paid by Tenant during any Lease Year is
less than the actual Lease Expenses Difference allocable to such Lease Year,
then Tenant shall, within thirty (30) days after receipt of the Actual
Statement, pay to Landlord the amount of such deficiency. The payment by Tenant
of any Monthly Payment or any year-end deficiency of Lease Expenses Difference
shall not be deemed a waiver of Tenant's right to contest Landlord's calculation
of Lease Expenses.

        6.4 LEASE EXPENSES DIFFERENCE CAP: Notwithstanding anything to the
contrary in this Lease, Lease Expenses Difference shall not include more than
one hundred eight percent (108%) of Controllable Operating Expenses of the
preceding Lease Year, or in the case of the first Lease Year, the Base Year.
"Controllable Operating Expenses" shall mean landscaping maintenance, parking
lot sweeping, plumbing, Tri-Water System maintenance, janitorial services and
supplies, trash removal, security and life safety, pest control, elevator
maintenance, parking and walkways, locks and keys, window washing, lighting
maintenance, roof maintenance, painting and sealing, general maintenance, paving
maintenance, windows, doors and screens, signs, common area maintenance, and
management fees.

        6.5 OPERATING EXPENSE RECORDS: Landlord shall maintain all operating
expense records for a period of five (5) years. Tenant or Tenant's
Representative shall have the right to inspect and photocopy any or all of the
operating expense records at the office of PacCor Management Company during
normal working hours upon twenty-four (24) hours written notice. Tenant shall
have the right to require an audit of Lease Expenses. Any amounts of Lease
Expenses Difference overpaid by Tenant shall be immediately refunded or shall be
credited against the Base Rent next due by Tenant. In the event Tenant's audit
determines that Lease Expense Difference for any Lease Year is overstated by Six
Thousand Two Hundred Fifty and no/100ths Dollars ($6,250.00) or more and the
Actual Statement did not reasonably disclose the facts underlying the
overstatement, then Landlord shall pay the reasonable cost of Tenant's audit.

                                    SECTION 7
                      USE AND MAINTENANCE OF THE PREMISES

        7.1 PERMITTED USE: Tenant may use the Premises for general office use
and for any other legally permitted use compatible with comparable office
buildings in the Sorrento Mesa area of San Diego, California, including software
development and testing.

                                    Page 17

<PAGE>

        7.2 INSURANCE: Tenant shall not do, bring or keep anything in or about
the Premises which is outside the scope of that which is normally contemplated
for the use specified in Section 7.1, that will cause a cancellation of any
insurance covering the Premises or the Project. If the rate of any insurance
carried by Landlord is increased as a result of Tenant's use (except as
contemplated by Section 7.1), Tenant shall pay to Landlord, within ten (10) days
after Landlord delivers to Tenant a notice of such increases, the amount of such
increase.

        7.3 COMPLIANCE WITH LAWS: Tenant shall comply with all laws concerning
the Premises and Tenant's use of the Premises. Landlord represents and warrants
that, as of the Commencement Date of this Lease, there are no violations within
the Project of the Americans With Disabilities Act 42 U.S.C. Section 1281 et.
seq. ("ADA") and any similar state and federal laws and that the Building and
Common Areas shall comply with ADA and any similar state and federal laws on the
Commencement Date. To the extent that the foregoing representation and warranty
is inaccurate or untrue, Landlord shall, at its sole expense and not as an
expense which shall be added to Building Operating Expenses or Common Area
Operating Expenses, be responsible for compliance with the ADA and any similar
state or federal law. The Work shall comply with the requirements of the ADA and
any similar state and federal laws. If the Premises do not comply with the ADA
or similar state or federal law during the Term of the Lease due to a change in
the ADA or similar state or federal law after the Commencement Date that
requires Tenant to comply with such changes as a condition to Tenant's continued
use of the Premises, then Tenant shall at its sole cost be responsible for
compliance with the ADA or any similar state and federal laws.

        7.4 HAZARDOUS WASTE OR NUISANCE: Landlord represents that to its
knowledge the Project is free of Hazardous Materials as defined below. Tenant
shall not use the Premises in any manner that will constitute waste, nuisance or
unreasonable annoyance to other tenants of the Project, or to owners or
occupants of nearby properties. Tenant shall not use the Premises for sleeping,
washing clothes, or the preparation, manufacture, or mixing of anything that
might emit any odor or objectionable noises or lights onto the Building or
nearby properties. Tenant shall neither bring into the Premises, nor permit the
bringing into the Premises of, any animal, motorcycle or other vehicle, except
for guide dogs or wheelchairs. Tenant and Landlord shall each strictly comply
with all statutes, laws, ordinances, rules, regulations, and precautions now or
hereafter mandated or advised by any federal, state or local law, regulation,
ordinance or rule or by any governmental agency with respect to the use,
generation, treatment, storage, disposal, release or threatened release of
hazardous, toxic or radioactive substance, materials or waste (collectively
"Hazardous Materials"). As used in this Section 7.4, Hazardous Materials
includes without limitation those substances identified in Section 66680 through
66685 of Title 22 of the California Administrative Code, Division 4, Chapter 30,
as amended from time to time, and those substances defined as "hazardous
substances," "hazardous materials," "hazardous wastes," "pollutants,"
"contaminants," "chemicals known to the State to cause cancer or reproductive
toxicity," "asbestos," "hydrocarbons (including

                                    Page 18

without limitation oil)," "toxic bearing dust" or other similar designations in
the Comprehensive Environmental Response, Compensation and Liability Act of
1980, as amended, 42 U.S.C. Sections 9601, et seq., the Hazardous Materials
Transportation Act, 49 U.S.C. Sections 1801, et seq., the Hazardous Substance
Account Act, Health & Safety Code Sections 25300, et seq., the Safe Drinking
Water and Toxic Enforcement Act of 1986, Health & Safety Code Sections 25249.5,
et seq., and any other federal, state or local statutes, laws, ordinances,
rules, regulations and precautions. Tenant shall not cause or allow any Tenant's
Representatives and/or Tenant's Invitees to cause any Hazardous Materials to be
used, generated, treated, stored, disposed of or released in, on or about the
Premises, except as allowed by law. Tenant shall indemnify, protect, defend by
counsel acceptable to Landlord, and hold Landlord and its successors, assigns
and mortgagees harmless from and against any and all claims, losses,
liabilities, costs and expenses, including all foreseeable and unforeseeable
consequential damages, except to the extent caused by Landlord's or Landlord's
Representative's negligence, willful misconduct, omission or breach of
obligations under this Lease, directly or indirectly arising out of the use,
generation, treatment, storage, disposal, release or threatened release of
Hazardous Materials by Tenant or any Tenant's Representatives and/or Tenant's
Invitees claiming under Tenant of Hazardous Materials at, on, beneath or from
the Project based on the Comprehensive Environmental Response, Compensation and
Liability Act, 42 U.S.C. Sections 9601, et seq., the Resource Conservation and
Recovery Act, 42 U.S.C. Sections 6901, et seq., the California Hazardous
Substance Account Act, Health & Safety Code Sections 25300, et seq., the
California Hazardous Waste Control Law, Health & Safety Code Sections 25100, et
seq., the Porter-Cologne Water Quality Control Act, Water Code Sections 13000,
et seq., or any other federal, state or local statute, law, regulation,
ordinance or rule. Landlord shall indemnify, protect, defend by counsel
acceptable to Tenant, and hold Tenant, Tenant's Representatives (as defined in
4.5) and Tenant's successors, assigns and mortgagees harmless from and against
any and all claims, losses, liabilities, costs and expenses, including all
foreseeable and unforeseeable consequential damages, except to the extent caused
by Tenant or Tenant's Representative's negligence, willful misconduct or breach
of its obligations under this Lease, directly or indirectly arising out of the
past, present or future use, generation, treatment, storage, disposal, release
or threatened release of Hazardous Materials at, on, beneath or from the Project

Porter-Cologne Water Quality Control Act, Water Code Sections 13000, et seq., or
any other federal, state or local statute, law, regulation, ordinance or rule.
Neither the written consent by Landlord to the use, generation, storage or
disposal of Hazardous Materials nor the strict compliance by Tenant with all
statutes, laws, ordinances, rules, regulations and precautions pertaining to
Hazardous Materials shall excuse Tenant from Tenant's obligations pursuant to
this Section 7.4. Likewise, neither the written consent by Tenant to the use,
generation, storage or disposal of Hazardous

                                    Page 19

<PAGE>

Materials nor the strict compliance by Landlord with all statutes, laws,
ordinances, rules, regulations and precautions pertaining to Hazardous Materials
shall excuse Landlord from Landlord's obligations pursuant to this Section 7.4.
Tenant's obligations pursuant to this Section 7.4 shall survive the termination
of this Lease. Tenant shall notify Landlord, as required by California Health &
Safety Code Section 25359.7, if Tenant knows or has reasonable cause to believe
that any Hazardous Material has come to be located on or beneath the Building.
On or before January 1, 1995, and each January 1 thereafter during the Term,
Tenant shall provide Landlord with a written list of all Hazardous Materials
used, generated, treated, stored, disposed of and released in, on or about the
Premises by Tenant during the prior calendar year and those Hazardous Materials
Tenant proposes to use, generate, treat, store, dispose of and release during
the next calendar year, except for substances which are customarily used or
found in typical offices, including without limitation copier and printer toner,
cleaning supplies, correction fluid and ink.

        7.5 DAMAGE AND OVERLOADING: Tenant shall be responsible for any damage
to the Premises or the Project caused by Tenant's Invitees and/or Tenant's
Representatives. No machinery, apparatus, or other appliance shall be used or
operated in or on the Premises that will in any manner injure the Premises or
Project. If Tenant, Tenant's Representatives or Tenant's Invitees cause damage
to the Premises or the Project, then Landlord shall have the right but not the
obligation to repair such damage and Tenant shall promptly reimburse Landlord
for Landlord's actual costs of such repair (to the extent that such costs exceed
available insurance proceeds) as Rent.

        7.6 ACCESS BY LANDLORD:

            (a) Landlord and/or Landlord's agent(s), employee(s), officer(s) or
independent contractor(s) of or retained by Landlord ("Landlord's
Representatives") shall have the right to enter the Premises at all reasonable
times upon twenty-four (24) hour prior written notice to Tenant (i) to determine
whether the Premises are in Good Condition (defined in Section 7.15) or whether
Tenant is complying with its obligations under this Lease, (ii) to do any
necessary maintenance or make any restoration to the Premises that the Landlord
has the right or obligation to perform under this Lease, (iii) to serve, post,
or keep posted any notices required or allowed under this Lease, (iv) to show
the Premises to brokers, agents, buyers, tenants or other persons interested in
a listing of, financing, sale or exchange of, or occupancy of the Premises or
the Project, and (v) to shore the foundations, footings, and walls of the
Premises and other improvements on the Real Property and to erect scaffolding
and protective barricades around and about the Premises or the Project, but not
so as to prevent entry to or use of the Premises and to do any other act or
thing necessary for the safety or preservation of the Premises or the Project if
any excavation or other construction is undertaken or is about to be undertaken
on any adjacent property or nearby street. Landlord shall have the right at any
and all times to enter the Premises for emergency purposes.

                                    Page 20

<PAGE>

            (b) Landlord shall not be liable for any inconvenience, disturbance,
loss of business, nuisance, or other damage arising out of Landlord's entry on
the Premises as provided in this Section 7.6, except damage resulting directly
from the negligent act, omission or willful misconduct of Landlord or Landlord's
Representatives. No provision of this Lease shall be construed as obligating
Landlord to perform any repairs, alterations or decorations except as otherwise
provided in this Lease or as expressly agreed in writing to be performed by
Landlord. Landlord shall have the right to run utility or other services and
facilities through the Premises as may be reasonably required, whether to
service the Premises or other premises, provided that the use of such space does
not have a materially adverse effect on or unreasonably interfere with Tenant's
use and enjoyment of the Premises. If during the last month of the Term, Tenant
shall have removed substantially all of its Personal Property and personnel from
the Premises, Landlord may enter the Premises and repair, alter and redecorate
the same without abatement of Base Rent or liability to Tenant and such acts
shall have no effect on this Lease. Any entry to the Premises obtained by
Landlord pursuant to this Section 7.6 shall not under any circumstances be
construed or deemed to be a forcible or unlawful entry into or detainer of the
Premises, or an eviction of Tenant from the Premises or any portion thereof.
Tenant shall not be entitled to an abatement or reduction of Base Rent because
of the exercise by Landlord of any rights under this Section 7.6. Landlord shall
conduct its activities on the Premises as allowed in this Section 7.6 in a
manner that will cause as little inconvenience, annoyance, or disturbance to
Tenant as reasonably feasible.

        7.7 SIGN: Tenant shall have the right to place, construct and maintain
one sign, not to exceed twenty-five (25) square feet in size and located as
mutually agreed to by Landlord and Tenant, at the top of the Building
("Sign"). The design, construction and maintenance of the Sign shall be
solely at Tenant's expense. Landlord makes no representation with respect to
Tenant's ability to obtain such approvals under applicable laws and regulations
or pursuant to that certain Declaration of Covenants, Conditions and
Restrictions for Unit No. 1 of Pacific Corporate Center, dated May 14, 1985 and
recorded as Instrument #85-169398 ("CC&R's", Exhibit "J"). In any event, the
Sign shall comply with all laws, regulations, CC&R's, and PID (Exhibit "K").
Tenant shall obtain any approvals required by laws, regulations and CC&R's. All
costs to remove the Sign upon the Expiration Date, Option Expiration Date or
earlier termination of the Lease shall be the liability of Tenant.

        7.8 PARKING: Subject to the terms of this Section 7.8 and so long as
Tenant is not in default under this Lease, Landlord grants to Tenant the right
to the non-exclusive use in common with other Project tenants of the parking lot
adjacent to and serving the Building of ninety (90) parking spaces, five (5) of
which will be reserved solely for Tenant, except for reserved parking granted to
any other tenants in the Project. Tenant's use of the parking lot shall be
subject to such reasonable rules which do not favor other Project tenants to the
detriment of Tenant, as Landlord may, in its sole discretion, adopt from time to
time with respect to use of the parking lot. Landlord shall cooperate with
Tenant, and shall take all reasonable steps necessary, to ensure that

                                    Page 21

<PAGE>

Tenant and Tenant's Representatives and Tenant's Invitees shall have access to
all parking spaces to which Tenant is entitled. Tenant shall not be charged for
the use of the parking lot unless the City of San Diego or other governmental
entity after the execution of this Lease assesses a tax, fee and/or excise on
the parking of motor vehicles in the parking lot, and then Tenant shall pay to
Landlord that portion of the tax, fee and/or excise based on Tenant's right to
non-exclusive parking of the entitled parking spaces.

        7.9 ALTERATIONS:

            (a) Tenant shall not make any alterations, improvements, repairs,
additions, installations, or changes of any nature in or to the Premises
(individually and collectively, "Alterations") without Landlord's prior written
consent, which consent shall not be unreasonably withheld or delayed more than
ten (10) days after Landlord's receipt of Tenant's request for Landlord's
consent. If written consent is obtained from Landlord, any construction
undertaken by Tenant in or to the Premises shall comply with all the terms and
provisions of Sections 7.9(b) and 7.9(c). Unless otherwise agreed to in writing
by Landlord and Tenant before such Alterations are made, all Alterations made by
Tenant shall become the property of Landlord and a part of the realty and shall
be surrendered to Landlord upon the Expiration Date, Option Expiration Date or
sooner termination of the Lease, or, at Landlord's election shall be removed
before the last day of the Term after receiving ninety (90) days prior written
notice from Landlord to Tenant or thirty (30) days after notice of Landlord's
election is given to Tenant in the event of earlier termination of the Lease.
All damage caused by such removal shall be repaired with all due diligence by
Tenant at its sole cost and expense.

            (b) Tenant must utilize only bondable licensed contractors for any
Alterations proposed to be made in or to the Premises. Tenant shall promptly
provide Landlord with copies of bid solicitations and bids received for all such
work.

            (c) Alterations whether installed by Tenant or Tenant's
Representatives at any time prior to or during the Term shall be completed only
in compliance with the following:

                (i) Except as to Alterations which are reasonably expected to
cost less than Ten Thousand Dollars ($10,000.00), no work shall commence without
(A) Landlord's prior written approval or written waiver of right to approve
Tenant's contractor, (B) certificates of insurance acceptable to Landlord from a
company or companies approved by Landlord, furnished to Landlord by Tenant's
contractor, for general liability and automobile liability with limits of not
less than $500,000.00 combined single limit, builder's risk insurance for the
value at risk, workers' compensation as required, endorsed to include Landlord
as an additional insured, (C) Landlord's prior written approval of detailed
plans and specifications for such work which approval may not be unreasonably
withheld or delayed more than ten (10) days after Landlord's receipt of Tenant's
request for approval, and (D) with respect to any

                                    Page 22

<PAGE>

after Landlord's receipt of Tenant's request for approval, and (D) with respect
to any work estimated to cost more the $30,000.00, procurement by Tenant or its
contractor, if required by Landlord, of both a performance and labor and
materials payment bond (or a single bond including such coverage) guaranteeing
lien-free completion of the work of improvements.

                (ii) Notwithstanding Section 7.9(c)(i), all work on any
Alterations shall be performed in conformity with a valid permit and all other
applicable permits or licenses when and where required by cognizant government
authority or agency, copies of which shall be furnished to Landlord before the
work is commenced, and any work not acceptable to any governmental authority or
agency having or exercising jurisdiction over such work, or not reasonably
satisfactory to Landlord, shall be promptly corrected at Tenant's sole cost and
expense. Notwithstanding any failure by Landlord to object to any such work,
Landlord shall have no responsibility thereof either to Tenant or to third
parties.

                (iii) Notwithstanding Section 7.9(c)(i), all work or any
Alterations shall be performed at such time and in such manner as Landlord may
reasonably schedule or designate. Tenant shall pay to Landlord, subject to
Tenant's prior written approval, any extraordinary costs incurred for monitoring
any substantial changes to the Premises.

                (iv) Tenant shall reimburse Landlord subject to Tenant's prior
written approval, for any extraordinary expense actually incurred by Landlord by
reason of faulty work performed by Tenant or its contractors, or by reason of
delays caused by such work, or by reason of inadequate cleanup.

                (v) Tenant or its contractors will in no event be allowed to
install plumbing, mechanical equipment, electrical wiring or fixtures,
acoustical or integrated ceilings, or partitions, unless such installation is
consistent with plans and specifications previously approved in writing by
Landlord.

                (vi) All data processing, photocopying, copying and other
special electrical equipment shall have a separate duplex outlet and to the
extent such equipment requires electrical power in excess of that allotted to
the Premises, such equipment shall be installed only under the supervision of
Landlord or its electrical contractor. Tenant assumes the risk of all damage,
costs, and expense which is incurred by Landlord or other Premises tenants as
the result of Tenant's installation of electrical equipment in the Premises
without the supervision of Landlord or its electrical contractor. Tenant shall
pay any additional costs on account of any increased support to the floor load
necessary thereof or for any other equipment.

                (vii) Tenant or its contractors shall, before the commencement
of any Alterations by Tenant in, on or around the Premises, give sufficient
notice thereof to Landlord for Landlord's preparation, posting and recordation
of any appropriate notices

                                    Page 23

successor or similar provision of law. Within ten (10) days after substantial
completion of any Alterations or repairs, Tenant or its contractor shall file
for record in the Office of the County Recorder in and for the county in which
the Premises is located, a notice of completion as permitted by law.

                (viii) All Alterations shall conform to the then applicable
Building Standards. The Building Standards may be reasonably amended during the
Term of the Lease.

        7.10 MECHANICS' LIEN: Tenant shall pay all costs for Alterations and
other construction done or caused to be done by it on the Premises. Tenant shall
keep the Premises free and clear of all mechanics' liens resulting from such
Alterations or other construction. Tenant shall have the right to contest the
correctness or validity of any such lien if, immediately on demand by Landlord,
Tenant procures and records a lien release bond, issued by a corporation
satisfactory to Landlord and authorized to issue surety bonds in California, in
an amount equal to one hundred fifty percent (150%) of the amount of the claim
of lien. The bond shall meet the requirements of California Civil Code Section
3143, shall indemnify Landlord against liability for such claim of lien and
shall hold the Project free from the effect of such claim of lien. In addition,
Landlord may require Tenant to pay Landlord's reasonable and necessary
attorneys' fees and costs in participating in such an action.

        7.11 INDEMNITY AND EXEMPTION OF LANDLORD FROM LIABILITY:

             (a) Except to the extent caused by the negligence or willful
misconduct of Landlord or Landlord's Representatives, Tenant shall indemnify,
protect and defend Landlord against all claims arising from (i) the use of the
Premises by Tenant, Tenant's Representatives and/or Tenant's Invitees, (ii) the
conduct of Tenant's business, (iii) any activity, work or things done, permitted
or suffered by Tenant or any of Tenant's Representatives in or about the
Premises or elsewhere, (iv) any breach or default in the performance of any
obligation to be performed by Tenant under this Lease, or (v) any negligence of
Tenant, Tenant's Representatives and/or Tenant's Invitees, and against all
reasonable costs, attorneys' fees, expenses and liabilities incurred in the
defense of any such claim and any action or proceeding brought on such claim.
Notwithstanding any other provision of this Lease, Tenant shall not indemnify,
protect or defend Landlord with respect to any past, present or future act or
omission relating to the use, generation, storage, discharge or disposal of
Hazardous Materials on or about the Project caused by any person other than
Tenant, Tenant's Representatives or Tenant's Invitees. If any action or
proceeding is brought against Landlord by reason of any such claim, Tenant upon
written notice from Landlord shall defend such action or proceeding at Tenant's
sole cost by counsel reasonably satisfactory to Landlord. Tenant assumes all
risk of damage to property and injury to persons in, upon or about the Premises
arising from any cause, and Tenant waives all claims against Landlord in respect
of such damage or injury, except to the extent caused by Landlord's or
Landlord's Representative's sole and exclusive gross negligent acts or willful
misconduct.

                                    Page 24

Representative's sole and exclusive gross negligent acts or willful misconduct.
Tenant's obligations pursuant to this Section 7.11 shall survive the termination
of this Lease.

             (b) Landlord shall not be liable for injury to Tenant's business or
any loss of income from such business or for damage or injury to the goods,
wares, merchandise, or other property or the person of Tenant, Tenant's
Representatives or Tenant's Invitees or any other persons in, upon or about the
Premises, whether such damage, loss or injury is caused by or results from
criminal acts, fire, steam, electricity, gas, water or rain, or from the
breakage, leakage, obstruction or other defects of pipes, sprinklers, wires,
appliances, plumbing, air conditioning or lighting fixtures; or from any other
cause, whether such damage, loss or injury results from conditions arising upon
the Premises or from other sources or places and regardless of whether the cause
of such damage, loss or injury or the means of repairing such damages, loss or
injury is inaccessible to Tenant.

        7.12 PREMISES CHANGES: This Lease shall not be affected or impaired by
any physical change to any part of the Project or any sidewalks, streets or
improvements nearby the Project, provided that access to the Premises, parking
for the Premises and Tenant's use of the Premises are not adversely materially
affected by such change and provided that such changes do not significantly and
adversely affect the safety of the Project. This Lease shall not be affected or
impaired by any change in the use of the Project, provided the Project is for
general office use and for any other legally permitted use compatible with
comparable office buildings in the Sorrento Mesa area of San Diego, California.

        7.13 SERVICES AND UTILITIES:

             (a) Heating, Ventilation, Air Conditioning System:

                 (i) Landlord has installed that portion of the water source

                 (iv) Upon Tenant's written request to Landlord, Landlord shall
install as a component of the Work and as part of the Tenant Improvement
Allowance a monitoring device to measure off-peak hours use of the Tri-Water
System or a bypass system to allow Tenant to operate the Tri-Water System during
off-peak hours to a portion of the Premises.

             (b) Landlord's Responsibility: Landlord shall provide to the
Building telephone service and electrical service to the utilities equipment
room in the Building. Landlord shall install water line(s) to the Building at
Landlord's expense. Landlord shall furnish elevator service consisting of
non-attended automatic elevators, lighting replacement for exterior standard

machines or equipment in the Premises which affect the temperature otherwise
maintained by the Tri-Water System for the Premises, Landlord reserves the right
to install supplementary air conditioning units in the Premises and the cost
thereof, including the cost of installation, operation and maintenance thereof,
shall be paid by Tenant to Landlord upon written demand by Landlord.

             (c) Interruption of Services: In the event of any interruption of
service required to be provided by Landlord hereunder, where such interruption
is caused by the negligence or willful misconduct of Landlord, Tenant shall be
entitled to abatement of Base Rent and Lease Expenses Difference in proportion
to the reasonable denial of use caused by the interruption, beginning on the
later of the third day after Tenant provides Landlord with notice of the
interruption or the actual date when Tenant stops using all or any affected
portion of the Premises because of the interruption, and continuing until the
restoration of the interrupted service. Notwithstanding the foregoing, Tenant
acknowledges that services to be supplied by Landlord hereunder may be
temporarily interrupted because of accidents, repairs, alterations, improvements
or other reasons beyond the reasonable control of Landlord. Except as set forth
in the next sentence of this Section 7.13(c) no such interruption shall (i) be
considered an eviction or disturbance of Tenant's use and possession of the
Premises; (ii) make Landlord liable to Tenant for damages; (iii) abate Basic
Rent or Lease Expenses Difference or (iv) relieve Tenant from performing its
obligations hereunder. Notwithstanding the preceding sentence, if any essential
services (such as Tri-Water System, passenger elevators, electricity or water)
supplied by Landlord are interrupted and the interruption does not result from
the negligence or willful misconduct of Landlord or Landlord's Representatives,
Tenant shall only be entitled to an abatement of Base Rent and Lease Expenses
Difference beginning on the fourth consecutive business day of the interruption
and continuing until the interrupted services are restored.

within the Premises during the Term.

               (e) Excessive Consumption: Tenant shall not connect any apparatus

Project using their premises as general office space, including limited
lunchroom facilities (as reasonably determined by Landlord), without first
procuring the written consent of Landlord, which will not be unreasonably
withheld provided that Tenant shall be responsible to pay for such excess use,
and in the event of consent, Landlord may cause to be installed a water meter
for the Premises to measure the amount of water consumed. The cost of any such
meter and of its installation, maintenance and repair shall be paid for by the
Tenant and Tenant agrees to pay Landlord promptly upon demand for all such water
consumed as shown by said meter, at the rates charged for such services by the
local public utility company plus any additional reasonable and necessary
expense incurred by Landlord in keeping account of the water so consumed. If a
separate meter is not installed, the excess cost for such water shall be
established by an estimate made by a utility company hired by Landlord at
Tenant's expense,

        7.14 RULES: Tenant and Tenant's Representatives shall observe faithfully
and comply strictly with the rules and regulations that are set forth in

janitorial services are supplied by Landlord as set forth in the janitorial

condition, with allowances for reasonable wear and tear ("Good Condition"), all
portions of the Premises, except those portions of the Premises to be maintained
by Landlord as expressly described in Section 7.15(b). Tenant shall be liable
for any damage to the Project resulting from the acts or omissions of Tenant or
Tenant's Representatives. If Tenant fails to maintain the Premises as provided
above, then after applicable periods of notice and periods to cure as set forth
in Section 12.1(b), Landlord shall have the right but not the obligation to
maintain the Premises and Tenant shall promptly reimburse Landlord for
Landlord's actual cost of such maintenance.

               (b) Landlord shall maintain, repair, replace and repaint (i) the
structural parts of the Building, which are limited to foundations, bearing and
exterior walls

                                    Page 27

(excluding glass doors which are part of Tenant's Premises), subflooring, and

provisions of California Civil Code Sections 1941 and 1942 with respect to
Landlord's obligations for tenantability of the Premises and Tenant's right to
make repairs and deduct the expenses of such repairs from rent.

        7.16 TENANT TO PAY PERSONAL PROPERTY TAXES: Tenant shall pay before
delinquent all taxes, assessments, license fees, and other charges levied or
assessed against, or based upon the value of Tenant's Personal Property
("Personal Property Taxes") that become payable during the Term. On written
demand by Landlord, Tenant shall furnish Landlord with written satisfactory
evidence of such payments. If any Personal Property Taxes are levied against
Landlord or Landlord's property, or if the assessed value of the Project is
increased by the inclusion of a value placed on Tenant's Personal Property, and
if Landlord pays such Personal Property Taxes or any taxes based on the
increased assessments caused by such Tenant's Personal Property, then Tenant, on
demand, shall immediately reimburse Landlord for the sum of the Personal
Property Taxes so levied against Landlord, or the proportion of taxes resulting
from such increase in Landlord's assessment. Landlord shall have the right to
pay such Personal Property Taxes or such proportion, and receive such
reimbursement, regardless of the validity of the levy.

                                    INSURANCE

        8.1 TENANT'S INSURANCE:

               (a) Public Liability and Property Damage Insurance: Tenant shall
procure at its sole cost and expense and keep in effect from the date of this
Lease at all times until the end of the Term, comprehensive general liability
insurance insuring against liability of Tenant, Tenant's Representatives,
Landlord, and Landlord's Representatives, arising out of or in connection with
Tenant's use or occupancy of the Premises or any part thereof, or the Project by
Tenant or Tenant's Representative. Such insurance shall include contractual
liability insurance coverage insuring Tenant's indemnity obligations under this
Lease. Such coverage shall have a minimum combined single limit of liability of
not less than $1,000,000 with a minimum general aggregate limit of
$1,000,000.00. Such policies shall be written to apply to property damage,
bodily injury, personal injury, premises medical payments, fire legal liability,

                                    Page 28
<PAGE>
general liability and other covered losses, however occasioned, occurring during
the policy term, naming the Landlord and Landlord's lender as additional
insureds, providing that such coverage shall be primary and that any insurance
maintained by Landlord shall be excess insurance only. Such coverage shall also
(i) delete any employee exclusion on personal injury coverage; (ii) include
employees as insureds, (iii) include liquor liability and (iv) include
employer's automobile non-ownership liability. All such insurance shall provide
for severability of interests or contain a cross-liability endorsement and shall
provide that an act or omission of one of the named insureds shall not reduce or
avoid coverage to the other named insureds; and shall afford coverage for all
claims based on acts, omissions, injury and damage, which claims occurred or
arose (or the onset of which occurred or arose) in whole or in part during the
policy period.

               (b) Automobile Liability Insurance: Tenant shall procure at its
sole cost and expense and keep in effect from the date of this Lease at
all times until the end of the Term, if applicable, Comprehensive Automobile
Liability insurance covering owned, non-owned and hired vehicles. Such coverage
shall have a minimum combined single limit of liability of not less than
$1,000,000.

               (c) Workers' Compensation Insurance: Tenant shall, if applicable,
maintain Workers' Compensation insurance in accordance with California law, and
employer's liability insurance with a limit of not less than $1,000,000.
Workers' Compensation insurance shall be endorsed to waive the insurer's right
of subrogation against Landlord.

               (d) Business Personal Property and Loss of Income Insurance:
Tenant shall, if applicable, maintain business personal property insurance to
pay for damage to or destruction of the Tenant's property from damage to or
destruction of the Premises. Such insurance shall insure against losses on an
"all-risk" type policy to the extent of at least one hundred percent (100%) of
the full replacement value of business personal property.

               (e) Maintaining Insurance: If Tenant fails during the Term to
maintain any insurance required to be maintained by Tenant under this Lease,
then Landlord may, at its option and in addition to Landlord's other remedies in
the event of default by Tenant, arrange for any such insurance, and Tenant shall
reimburse Landlord for any premiums for any such insurance within five (5)
business days after Tenant receives a copy of the premium notice. If such
premiums are allocable to a period, a portion of which occurs during the Term
and the remainder of which occurs before or after the Term, then such premiums
shall be apportioned between Landlord and Tenant based upon the number of days
during such period that occurred during the Term and the number of days that
occurred before or after the Term, such that Tenant pays for the premiums that
are allocable to the period during the Term. Insurance required to be maintained
by Tenant under this Lease (i) shall be issued as a primary policy by insurance
companies authorized to do business in the State of California with a Best's
rating of a least "A"

                                     Page 29
<PAGE>
and a Best's financial size category rating of at least "VIII", as set forth in
the most current edition of Best's insurance reports or such higher rating as
may be required by Landlord's lender, (ii) shall name the Additional Insureds as
additional named insureds as required by the Lease, (iii) shall constitute
"occurrence" based coverage, without provision for subsequent conversion to
"claims" based coverage, and (iv) shall not be cancelable or subject to
reduction of coverage or other modification except after thirty (30) days' prior
written notice to Landlord and any lender. Tenant shall, at least thirty (30)
days prior to the expiration of any such policy, furnish Landlord with a renewal
or binder of such policy. Tenant shall, upon request from Landlord, promptly
deliver to Landlord copies of such policy or policies or certificates evidencing
the existence and amounts of such insurance together with evidence of payment of
premiums. Any policy required to be maintained by Landlord or Tenant under this
Lease may be maintained under a so-called "blanket policy" insuring other
parties and/or other locations, so long as the amount of insurance and type of
coverage required to be provided under this Lease is not thereby diminished,
changed or adversely affected.

               (f) All insurance coverage, terms and conditions described in
this Section 8.1 shall be evidenced by a Certificate of Insurance issued to
Landlord. A copy of all insurance policies issued to Tenant during the Term
shall be forwarded to Landlord within sixty (60) days after the Commencement
Date.

               (g) If at any time during the Term the amount or coverage of
insurance which Tenant is required to carry under this Section 8.1 is, in
Landlord's reasonable judgment, materially less than that amount or type of
insurance coverage typically carried by owners or tenants of properties located
in San Diego, California, which are similar in size and used for similar
purposes as the Premises, Landlord shall have the right to require Tenant to
increase the amount or change the types of insurance coverage required under
this Section 8.1.

        8.2 Landlord's Insurance: Landlord shall, at its expense, maintain in
effect at all times during the Term: a policy or policies of "all risk" fire,
general liability and extended coverage insurance, including at least six (6)
months rental interruption insurance, with vandalism and malicious mischief
endorsements, coverage with respect to increased costs due to building
ordinances, demolition coverage, boiler and machinery insurance, sprinkler
leakage coverage, in each case to the extent of at least one hundred percent
(100%) of the full replacement value of the Building and Adjacent Building and
any future building on the Project. If Landlord fails during the Term to
maintain any insurance required to be maintained by Landlord under this Lease,
then Tenant may, at its election, arrange for any such insurance, and Tenant may
require that Landlord reimburse Tenant for any premiums for any such insurance
within five (5) days after Landlord or Tenant's receipt of the premium notice.
Insurance required to be maintained by Landlord under this Lease (a) shall be
issued as a primary policy by insurance companies authorized to do business in
California with a Best's Rating of at least "A" and a Best's Financial Size
Category rating of at least "VIII," as set forth in the most current edition of
"Best's Insurance Reports, or such higher rating as may be

                                    Page 30
<PAGE>

required by any lender, (b) shall name Tenant and any lender or other party as
Tenant may elect as additional named insureds, (c) shall constitute "occurrence"
based coverage, without provision for subsequent conversion to "claims" based
coverage, and (d) shall not be cancelable or subject to reduction of coverage or
other modification except after thirty (30) days' prior written notice to Tenant
and any lender. Landlord shall, at least thirty (30) days prior to the
expiration of each such policy, furnish Tenant with a renewal or "binder" of
such policy. Landlord shall, upon request from Tenant, promptly deliver to
Tenant copies of such policy or policies or certificates evidencing the
existence and amounts of such insurance together with evidence of payment of
premiums. The premiums, costs and expenses and deductibles of and/or with
respect to any such insurance shall be included in the Building Operating
Expenses. Landlord shall not increase the amount of insurance coverage beyond
that which was in place during the Base Year, other than reasonable increases to
reflect inflation or an increase in value of the insured property. Landlord
shall not increase the types of insurance coverages beyond that which was in
place during the Base Year unless commercially reasonable and in such event the
Operating Expenses for the Base Year shall be increased by the insurance premium
that would have been paid had the insurance been obtained by Landlord.

                                   SECTION 9
                                  DESTRUCTION

        9.1 RISK COVERED BY INSURANCE:

               (a) If during the Term the premises is totally or partially
destroyed, rendering the Premises totally or partially inaccessible or unusable,
Landlord shall, subject to Sections 9.1(b) and 9.1(c), restore the Premises to
substantially the same condition as it was in immediately before the
destruction. Such destruction shall not terminate this Lease except as provided
in this Section. If, however, then-existing laws do not permit such restoration,
Landlord or Tenant may terminate this Lease by giving written notice to the
other party.

               (b) If Landlord determines that the cost of such restoration
exceeds the amount of proceeds received by Landlord from any insurance
maintained by Landlord, then Landlord may elect to terminate this Lease by
giving notice to Tenant within sixty (60) days after such destruction or within
sixty (60) days after Landlord's receipt of such proceeds, whichever is later.
If Landlord gives such notice of termination, then this Lease shall terminate as
of forty-five (45) days after Landlord's notice of termination, unless Tenant
provides Landlord with written notice of its election to pay the amount by which
the cost of such restoration exceeds the amount of proceeds received by Landlord
("Notice To Restore"), in which event this Lease shall remain in full force and
effect. Tenant shall have thirty (30) days after Notice To Restore to pay the
excess cost of restoration either to Landlord or to an escrow account to be used
for restoration.

               (c) Within thirty (30) days after such destruction, Landlord
shall notify

                                    Page 31
<PAGE>

Tenant in writing whether or not, based on Landlord's determination, the
Premises can be restored within six (6) months after the date of such
destruction. If such restoration cannot be completed within such six (6) month
period, either party may terminate this Lease by giving written notice to the
other party within twenty (20) days after the date of Landlord's written notice.
If Landlord determines that the Premises can be restored within such six (6)
month period and neither party terminates this Lease pursuant to this Section 9,
Landlord shall use its reasonable efforts to restore the Premises within such
six (6) month period to substantially the same condition as it was in
immediately before the destruction. Notwithstanding the foregoing, if due to any
delay or fault on the part of Landlord the Premises are not in fact restored
within seven (7) months from the date of destruction, then Tenant may terminate
this Lease without further liability to Landlord by giving Landlord written
notice of termination, such termination to be effective immediately upon the
giving of such notice.

        9.2 ABATEMENT OR REDUCTION OF RENT: Except as otherwise provided herein,
in case of any destruction to the Premises, all obligations of Tenant under this
Lease shall remain in effect, except that Base Rent and Lease Expenses
Difference shall be abated or reduced, between the date of such destruction and
the date of completion of restoration, by the ratio of (a) the area of the
Premises rendered unusable or inaccessible by the destruction to (b) the area of
the Premises prior to such destruction.

        9.3 LOSS DURING LAST PART OF TERM OR EXCEEDING TWENTY-FIVE PERCENT (25%)
OF REPLACEMENT VALUE: Notwithstanding any other provision of this Lease, if any
destruction to the Premises occurs during the last year of the Term, or if, at
any time during the Term, there is any destruction to the Premises that exceeds
twenty-five percent (25%) of the then replacement value of the Premises,
Landlord or Tenant may terminate this Lease by giving written notice to the
other not more than thirty (30) days after such destruction, in which case (a)
neither Landlord nor Tenant shall have any obligation to restore the Premises,
(b) Landlord shall retain all insurance proceeds relating to such destruction
except for insurance proceeds relating to the loss of or damage to Tenant's
Personal Property or loss of business, and (c) this Lease shall terminate as of
thirty (30) days after such notice of termination.

        9.4 LIMITATION ON LANDLORD'S RESTORATION OBLIGATION: If Landlord is
required or elects to restore the Premises as provided in Section 9.1, Landlord
shall not be required to restore any of Tenant's Alterations which were
constructed without Landlord's written consent or any of Tenant's Personal
Property, unless they are an integral part of the Premises and specifically
covered by insurance proceeds received by Landlord, such excluded items being
the sole responsibility of Tenant to restore.

                                   SECTION 10

               (c) "Award" shall mean all compensation, sums or anything of
value awarded, paid, or received on a total or partial Condemnation of the
Project; and

               (d) "Condemnor" shall mean any public or quasi-public authority,
or private corporation or individual, having the power of Condemnation.

        10.2 GOVERNED BY LEASE: If during the Term, or during the period of time
between the execution of this Lease and the Commencement Date, there is any
taking of all or any part of the Project or any interest in this Lease by
Condemnation, the rights and obligations of Landlord and Tenant shall be
determined pursuant to this Section 10.

        10.3 TOTAL TAKING: If greater than fifty percent (50%) of the Premises
are taken by Condemnation or more than thirty percent (30%) of the available
parking area is taken by Condemnation, this Lease shall terminate on the Date of
Taking.

        10.4 PARTIAL TAKING: if any portion, but not all, of the Premises is
taken by Condemnation, this Lease shall remain in effect, except that Tenant may
elect to terminate this Lease if the remaining portion of the Premises is, in
Tenant's reasonable opinion, rendered unsuitable for Tenant's continued use of
the Premises. If Tenant elects to so terminate this Lease, Tenant must exercise
its right to terminate by giving notice to Landlord within sixty (60) days after
the date that the nature and the extent of the taking have been finally
determined ("Determination Date"), which notice shall set forth the date of
termination. Such termination date shall not be earlier than thirty (30) days
nor later than ninety (90) days after Tenant has notified Landlord of its
election to terminate; except that this Lease shall terminate on the Date of
Taking if the Date of Taking falls on a date before the date of termination as
designated by Tenant. If Tenant does not so notify Landlord within sixty (60)
days after the Determination Date, all obligations of Tenant under this Lease
shall remain in effect, except that Base Rent and Lease Expenses shall be
reduced by the ratio of (a) the area of the Premises taken to (b) the area of
the Premises immediately prior to the Date of Taking.

        10.5 AWARD: The Award shall belong to and be paid to Landlord, Tenant
shall have no right to any part of the Award, and Tenant assigns to Landlord all
of Tenant's right, title and interest in and to any part of the Award, except
that Tenant shall receive from the Award an amount equal to the value of
Tenant's leasehold interest and any

                                    Page 33
<PAGE>

sum paid expressly to Tenant from the Condemnor for relocation, the cost of
tenant improvements which were paid for by Tenant and not part of the Tenant
Improvement Allowance, the value of Alterations and loss of goodwill.

        10.6 TEMPORARY TAKING: The taking of the Premises or any part of the
Premises by military or other public authorities shall constitute a taking of
the Premises by Condemnation only when the use and occupancy by the taking
authority is continued for longer than one hundred eighty (180) consecutive
days. During the one hundred eighty (180) day period, all obligations of Tenant
under this Lease shall remain in effect, except that Base Rent shall be abated
or reduced during such period of taking by the ratio of (a) the area of the
Premises taken to (b) the area of the Premises immediately prior to the Date of
Taking, and Landlord shall be entitled to any Award related to such taking.

        10.7 WAIVER OF STATUTE: Landlord and Tenant waive the provision of
California Code of Civil Procedure Section 1265.130 allowing Landlord or Tenant
to petition the superior court to terminate this Lease in the event of a partial
taking of the Premises.

                                   SECTION 11
                            ASSIGNMENT AND SUBLETTING

        11.1 ASSIGNMENT:

               (a) If Tenant is not in default of the Lease, Tenant may assign
any portion of Premises to any related entity, parent company, subsidiary or
affiliate ("Affiliate") without Landlord's consent.

               () Except for an Affiliate, Tenant shall not assign, enter into a
license or concession agreement for, hypothecate or otherwise divest itself of
this Lease or any of its rights under this Lease or permit any third party or
parties other than Tenant to occupy the Premises or any portion thereof without
Landlord's prior written consent, which consent shall not be unreasonably
withheld or delayed, but is subject to the terms and conditions contained in
this Section 11.

               (c) For purposes of this Lease, each of the following events
shall be deemed to constitute an assignment of this Lease:

                      (i) any assignment or transfer of this Lease, or any
interest in this Lease, voluntarily, involuntarily, by operation of law or
otherwise;

                      (ii) any mortgage, hypothecation, pledge, or collateral
assignment of this Lease or any interest in this Lease;

                                    Page 34
<PAGE>

                      (iii) any sale, transfer, grant of concessions or
licenses, or other disposition of this Lease, any interest in this Lease or all
or any portion of the Premises;

                      (iv) any assignment, transfer, disposition, sale, or
acquisition of more than fifty percent (50%) of the shares of Tenant's voting
stock by any person, entity, or group of related persons or affiliated entities,
whether in a single transaction or in a series of related or unrelated
transactions that results in a Change of Control (as hereinafter defined). For
purposes of this Lease, a "Change of Control" shall mean a change in the
identity of the person or persons exercising, or who may exercise, effective
control of the management of Tenant's business, unless such change (a) does not
materially impair Tenant's financial condition immediately after such change has
occurred; or (b) the change results from either (i) a registered public offering
of shares of Tenant's stock; (ii) the acquisition of Tenant by a company whose
shares are publicly traded; (iii) the trading of shares of Tenant listed on a
recognized national securities exchange or a nationally recognized automated
quotation system (such as the NASDAQ quotation system); or (iv) the transfer of
an equity interest in Tenant for purposes of estate or tax planning or by reason
of a distribution of shares held by a partnership to its partners; and

                      (v) any issuance of voting stock of Tenant to any person,
entity, or group of related persons or affiliated entities, whether in a single
transaction or in a series of related or unrelated transactions, which results
in Change of Control as defined above.

               (d) At least fifteen (15) days prior to entering into any
assignment of this Lease of all or any portion of the Premises, Tenant shall
submit to Landlord the form of such proposed assignment, and a written notice
("Tenant's Notice") setting forth in reasonable detail (i) the name and address
of the proposed assignee, (ii) the terms and conditions of the proposed
assignment, including without limitation the proposed effective date of the
assignment, which shall be at least thirty (30) days after Tenant's notice is
given, (iii) the nature and character of the business of the proposed assignee,
and (iv) current banking, financial, and other credit information, including
prior year's federal tax return, if available, (all of which information
Landlord agrees to treat as strictly confidential and not disclose or
disseminate to third parties) relating to the proposed assignee, in reasonably
sufficient detail, to enable Landlord to determine the proposed assignee's
financial responsibility.

               (e) Within twenty (20) days after Landlord's receipt of Tenant's
Notice and the form of assignment, Landlord shall notify Tenant whether Landlord
has consented to the proposed assignment. Any consent granted by Landlord in any
instance shall not constitute a consent with respect to any other instance or
request. If Landlord consents to any proposed assignment and Tenant fails to
consummate such assignment within one hundred eighty (180) days after such
consent, then such

                                    Page 35
<PAGE>

consent shall be deemed withdrawn and Tenant shall be required again to comply
with this Section 11 before assigning this Lease or any portion of the Premises.

               (f) Landlord shall not have unreasonably withheld its consent
with respect to any assignment if (i) Landlord shall not have received Tenant's
Notice as provided above, (ii) the nature and character of the proposed assignee
and the proposed use and occupancy of the Premises by the proposed assignee is
not in keeping with the dignity and character of the Premises and the
surrounding area, (iii) the proposed assignment will result in the diminution of
the value or marketability of the Premises, or (iv) the proposed assignee's use
of the Premises may reasonably conflict with other uses in the Premises. Tenant
acknowledges that Tenant's Notice shall be ineffective if Tenant is in material
default with respect to any provision under this Lease.

               (g) Notwithstanding any provision of this Lease to the contrary,
a merger or consolidation of Tenant with or into another corporation (including
a merger or consolidation that results in assignment or transfer of this Lease)
will not require the consent of Landlord, provided that the financial condition
of the surviving entity is equal to or greater than Tenant's financial condition
immediately prior to the Change of Control.

        11.2 SUBLEASE:

               (a) If Tenant is not in default of the Lease, Tenant may sublet
all or a portion of the Premises to an Affiliate without Landlord's consent.

               (b) If Tenant is not in default of the Lease, Tenant may sublease
all or a portion of the Premises to anyone, upon Landlord's prior written
consent, which consent shall not be unreasonably withheld.

               (c) Any sublease of all or a portion of the Premises shall be in
accordance with the terms and conditions of this Section 11 and all other
applicable terms and conditions of this Lease. Tenant's request to sublease all
or a portion of the Premises to anyone other than an Affiliate shall be in the
form of the Tenant's Notice as set forth in Section 11.1(d).

               (d) Any sublease of all or any portion of the Premises must
contain the following provisions, which provisions, whether contained in such
sublease nor not, shall apply to such sublessee:

                      (i) Such sublease shall be subject and subordinate to all
of the provisions of this Lease (including all exhibits) and any subsequent
amendments of this Lease;

                                    Page 36
<PAGE>

                      (ii) At Landlord's option, in the event of cancellation or
termination of this Lease for any reason or the surrender of this Lease, whether
voluntarily, involuntarily, or by operation of law, prior to the expiration of
such sublease, the subtenant shall make full and complete attornment to Landlord
for the balance of the term of such sublease, provided that Landlord agrees in
writing not to disturb subtenant's right to occupy the subleased area as long as
such sublessee is in compliance with its obligations under such sublease. The
subtenant shall execute and deliver to Landlord an agreement of attornment
reasonably satisfactory to Landlord within five (5) days after requested by
Landlord; and

                      (iii) No sublessee shall be permitted to further sublet
all or any portion of the subleased space without Landlord's prior written
consent.

               (e) Tenant shall submit all subleases to Landlord prior to
execution for Landlord's review and approval, which shall not be unreasonably
withheld or delayed more than seven (7) days after Landlord's receipt of any
sublease.

        11.3 TENANT AND ASSIGNEE OR SUBLESSEE FULLY LIABLE: No assignment of
this Lease nor any sublease of all or any portion of the Premises shall release
or discharge Tenant from any liability, whether past, present, or future, under
this Lease and Tenant shall continue to remain primarily liable under this Lease
except as may be executed by Tenant and Landlord in writing. The assignee of any
assignment of this Lease, and the sublessee of any sublease of all or any
portion of the Premises, shall execute, acknowledge, and deliver to Landlord an
agreement satisfactory to Landlord in which the assignee or sublessee assumes
and agrees to be bound by all of the provisions of this Lease.

        11.4 ASSIGNMENT OF RENTS: Tenant irrevocably assigns to Landlord, as
security for Tenant's obligations under this Lease, all rent from any subletting
of all or any portion of the Premises, and Landlord, as assignee and as special
attorney-in-fact for Tenant, or a receiver for Tenant appointed on Landlord's
application, may collect such rent and apply it toward Tenant's obligations
under this Lease, except that, unless Tenant defaults under this Lease, Tenant
shall have the sole right to collect such rent.

        11.5 EQUAL DIVISION OF SUBLEASE PREMIUM: Landlord and Tenant shall share
equally any "Premium" (as defined below) arising from the sublease of any
portion of the Premises to any entity which is not an Affiliate. For purposes of
this paragraph "Premium" shall mean all sums received by Tenant under the
sublease which exceed the Rent attributable to the subleased portion of the
Premises, after deducting (a) all reasonable expenses of Tenant incurred in
connection with such sublease amortized on a straight line basis over the
initial term of the sublease, including without limitation legal costs,
brokerage commissions, rent abatement and other concessions, lease takeover,
subtenant improvement costs, the unamortized value of Tenant's leasehold
improvements, downtime, and cash payments, (b) any utility costs paid by Tenant
which is attributable to such subleased premises, and (c) any Additional Rent
paid by

                                    Page 37
<PAGE>

Tenant which is attributable to such subleased premises. The determination of
Base Rent attributable to the subleased portion of the Premises shall be made on
the basis of the ratio of the rentable square footage in the subleased portion
to the Rentable Square Footage.

                                   SECTION 12
                              DEFAULT AND REMEDIES

        12.1 DEFAULT: The occurrence of any of the following shall constitute a
material default and breach of this Lease by Tenant:

               (a) the failure by Tenant to pay Rent as and when due, where such
failure shall continue for a period of five (5) business days after written
notice of such failure from Landlord to Tenant. In the event that Landlord
serves Tenant with a Notice to Pay Rent or Quit pursuant to applicable statutes
set forth in California Code of Civil Procedure, such Notice to Pay Rent or Quit
shall also constitute the notice of such failure;

               (b) the failure by Tenant to observe or perform any of the
provisions of this Lease to be observed or performed by Tenant, other than
described in Section 12.1(a), where such failure shall continue for a period of
thirty (30) days after written notice of such failure from Landlord to Tenant;
provided, however, that if the nature of Tenant's default is such that more than
thirty (30) days are required for its cure, then Tenant shall not be deemed to
be in default if Tenant commenced such cure within such thirty (30) day period
and thereafter diligently prosecutes such cure to completion within sixty (60)
days after Landlord's written notice; or

               (c) the making by Tenant of any general arrangement or assignment
for the benefit of creditors; Tenant's becoming bankrupt, insolvent or a
"debtor" as defined in 11 U.S.C. Section 101, or any successor statute (unless,
in the case of a petition filed against Tenant, such petition is dismissed
within sixty (60) days after its original filing); the institution of
proceedings under bankruptcy or similar laws in which Tenant is the debtor or
bankrupt; the appointing of a trustee or receiver to take possession of
substantially all of Tenant's assets located at the Premises or of Tenant's
interest in this Lease (unless possession is restored to Tenant within sixty
(60) days after such taking); or the attachment, execution of judicial seizure
of substantially all of Tenant's assets located at the Premises or Tenant's
interest in this Lease (unless such attachment, execution or judicial seizure is
discharged within sixty (60) days after such attachment, execution or judicial
seizure).

        12.2 LANDLORD'S REMEDIES: Landlord shall have the following remedies if
Tenant commits a default or breach under this Lease; these remedies are not
exclusive, but are cumulative in addition to any remedies provided elsewhere in
this Lease or now or later allowed by law.

                                    Page 38
<PAGE>

               (a) Continuation of Lease: No act by Landlord (including without
limitation the acts set forth in this Section 12.2(a)) shall terminate Tenant's
right to possession unless Landlord notifies Tenant in writing that Landlord
elects to terminate Tenant's right to possession. As long as Landlord does not
terminate Tenant's right to possession, Landlord may (i) continue this Lease in
effect, (ii) continue to collect rent when due and enforce all the other
provisions of this Lease, (iii) enter the Premises and relet them, or any part
of them, to third parties for Tenant's account, for a period shorter or longer
than the remaining term of this lease, and (iv) have a receiver appointed to
collect rent. Tenant shall immediately pay to Landlord all costs Landlord
reasonably incurs in such reletting, including, without limitation, brokers'
commissions, attorneys' fees, advertising costs and expenses of remodeling the
Premises of such reletting.

               (b) Rent from Reletting: If Landlord elects to relet all or any
portion of the Premises as permitted by Section 12.2(a), rent that Landlord
receives from such reletting shall be applied to the payment of, in the
following order and priority, (i) any indebtedness due from Tenant to Landlord
(other than Base Rent), (ii) all costs reasonably incurred by Landlord in such
reletting, including without limitation any brokers', finders', or leasing
agents' commissions, charges or fees, and (iii) Base Rent due and unpaid under
this Lease. After applying such payments as referred to above, any sum remaining
from the rent Landlord receives from such reletting shall be held by Landlord
and applied in payment of future Base Rent as it becomes due under this Lease.
In no event shall Tenant be entitled to any excess rent received by Landlord.

               (c) Termination of Tenant's Right to Possession: Landlord may
terminate Tenant's right to possession of the Premises at any time, by notifying
Tenant in writing that Landlord elects to terminate Tenant's right to
possession. On termination of this Lease, Landlord has the right to recover
from Tenant (i) the worth at the time of the award of the unpaid Base Rent which
had been earned at the time of such termination, (ii) the worth at the time of
the award of the amount by which the unpaid Base Rent which would have been
earned after such termination until the time of award exceeds the amount of such
loss of Base Rent that Tenant proves could have been reasonably avoided, (iii)
the worth at the time of the award of the amount by which the unpaid Base Rent
for the balance of the Term after the time of award (had there been no such
termination) exceeds the amount of such loss of Base Rent that Tenant proves
could be reasonably avoided, and (iv) any other amount necessary to compensate
Landlord for all detriment proximately caused by Tenant's failure to perform
Tenant's obligations under this Lease or in the ordinary course of things would
be likely to result therefrom. The "worth at the time of the award" of the
amounts referred to in Sections 12.2(c)(i) and 12.2(c)(ii) is to be computed by
allowing interest at a rate equal to ten percent (10%) per annum, but in no
event greater than the maximum rate permitted by applicable law. The "worth at
the time of the award" of the amount referred to in Section 12.2(c)(iii) is to
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 (1%), but in
no event greater than the maximum rate permitted by applicable law.

                                    Page 39
<PAGE>

               (d) Landlord's Right to Cure Default: Landlord, at any time after
Tenant commits a default or breach under this Lease, may cure such default or
breach at Tenant's sole cost. If Landlord at any time, by reason of Tenant's
default or breach, pays any sum or does any act that requires the payment of any
sum, such sum shall be due immediately from Tenant to Landlord at the time such
sum is paid, and shall be deemed additional rent under this Lease.

        12.3 INTEREST AND LATE CHARGES: Rent not paid within five (5) days after
its due date shall bear interest from the date due at a rate equal to ten
percent (10%) per annum, but in no event greater than the maximum rate permitted
by applicable law. Late payment by Tenant to Landlord of Rent will cause
Landlord to incur cost not contemplated by this Lease, the exact amount of which
would be impracticable or extremely difficult to fix. Such costs include,
without limitation, processing, collection and accounting charges, and late
charges that may be imposed on Landlord by the terms of any Mortgage covering
the Premises. Therefore, if any Rent is not received by Landlord within five (5)
business days after notice to Tenant of such overdue payment from Landlord to
Tenant, Tenant shall pay to Landlord an additional sum of five percent (5%) of
such overdue amount as a late charge ("Late Charge"). Landlord and Tenant agree
that the Late Charge represents a fair and reasonable estimate of the costs that
Landlord will incur by reason of any late payment by Tenant, and therefore this
Section 12.3 is reasonable under the circumstances existing at the time this
Lease is executed. Acceptance of the Late Charge by Landlord shall not
constitute a waiver of Tenant's default with respect to such overdue amount, nor
prevent Landlord from exercising any of the other rights and remedies available
to Landlord under this Lease.

        12.4 QUARTERLY PAYMENTS: In the event that a Late Charge is payable
under this Lease, whether or not collected, for three (3) consecutive
installments of Rent or in the event Rent is paid more than thirty (30) days
late twice due under this Lease during any twelve (12) month period, then Base
Rent, and Monthly Payment, shall , at Landlord's election by written notice to
Tenant, become due and payable quarterly in advance, rather than monthly, for a
period of six (6) months. If a Late Charge is payable under the Lease, whether
or not collected, for two (2) installments of Rent during the twelve (12)
calendar months following such six (6) month period, then Base Rent and Monthly
Payment shall automatically become due and payable quarterly in advance for a
period of one (1) year, after which time Rent shall revert back to monthly
payments. If any payment is not timely paid during such one year period, then
Base Rent and Monthly Payment shall automatically become due and payable
quarterly in advance for the remaining Term of the Lease. All monies paid to
Landlord under this Section 12.4 may be commingled with other monies of Landlord
and shall not bear interest.

        12.5 WAIVER: No delay or omission in the exercise of any right or remedy
of Landlord in the event of any default by Tenant shall impair such right or
remedy of be construed as a waiver. The receipt and acceptance by Landlord of
delinquent Rent shall not constitute a waiver of any default other than the
particular rent payment accepted. Landlord's receipt and acceptance from Tenant,
on any date ("Receipt

                                    Page 40
<PAGE>

Date"), of an amount less than rent due on such Receipt Date, or to become due
(pursuant to Section 4 or Section 6) at a later date but applicable to a period
prior to such Receipt Date, shall not release Tenant of its obligation (a) to
pay the full amount of such rent due on such Receipt Date or (b) to pay when due
the full amount of such rent to become due at a later date but applicable to a
period prior to such Receipt Date. No act or conduct of Landlord, including
without limitation, the acceptance of the keys to the Premises, shall constitute
an acceptance by Landlord of the surrender of the Premises by Tenant before the
Expiration Date or Option Expiration Date. Only a written notice from Landlord
to Tenant stating Landlord's election to terminate Tenant's right to possession
of the Premises shall constitute acceptance of the surrender of the Premises and
accomplish a termination of this Lease. Landlord's consent to or approval of any
act by Tenant requiring Landlord's consent or approval shall not be deemed to
waive or render unnecessary Landlord's consent to or approval of any other or
subsequent act by Tenant. Any waiver by Landlord of any default by Tenant must
be in writing and shall not be a waiver of any other default concerning the same
or any other provision of this Lease.

        12.6 NOTICE OF DEFAULT: Landlord shall not be deemed to be in default in
the performance of any obligation required to be performed by Landlord unless
and until it has failed to perform such obligation within thirty (30) days after
Landlord's receipt of written notice from Tenant specifying Landlord's failure
to perform such obligation. However, if the nature of Landlord's obligation is
such that more than thirty (30) days are required for its performance, then
Landlord shall not be deemed to be in default if it shall commence such
performance within such thirty (30) day period and thereafter diligently
prosecutes the same to completion.

                                   SECTION 13
             SUBORDINATION, ATTORNMENT, ESTOPPEL, AND NON-DISTURBANCE

        13.1 SUBORDINATION: This Lease and Tenant's rights under this Lease are
subject and subordinate to any mortgage, loan secured by a deed of trust, or
other written security instrument or agreement affecting the Project that
constitutes security for the payment of a debt or performance of an obligation
(each, a "Mortgage"), and to all renewals, modifications, consolidations,
replacements or extensions thereof, now or hereafter affecting the Premises. The
provisions of this Section 13.1 shall be self-operative, and no further
instrument of subordination shall be required. Within fifteen (15) days after
written notice from Landlord, Tenant shall execute and deliver any instruments
that Landlord and the holder of any Mortgage may reasonably request to evidence
such subordination so long as the instruments do not modify this Lease, decrease
or adversely affect Tenant's rights under this Lease, or increase Tenant's
duties or obligations hereunder. If Tenant fails to execute and deliver any such
instrument(s) within fifteen (15) days after such notice, Tenant irrevocably
appoints Landlord as Tenant's special attorney-in-fact to execute and deliver
such instruments on behalf of Tenant. If Landlord executes documents on behalf
of Tenant pursuant to

                                    Page 41
<PAGE>

the special power-of-attorney, it shall be deemed that Tenant has not waived any
rights against Landlord solely due to the use of the special power-of-attorney
by Landlord.

        13.2 ATTORNMENT: If the holder of any Mortgage shall hereafter succeed
to the Landlord under this Lease, Tenant shall attorn to and recognize such
successor as the Landlord under this Lease, and shall promptly execute and
deliver any instruments that may be necessary to evidence such attornment. If
Tenant fails to execute and deliver any such instrument(s) within fifteen (15)
days after written notice from Landlord, Tenant irrevocably appoints Landlord as
Tenant's special attorney-in-fact to execute and deliver such instruments on
behalf of Tenant. If Landlord executes documents on behalf of Tenant pursuant to
the special power-of-attorney, it shall be deemed that Tenant has not waived any
rights against Landlord or such successor solely due to the use of the special
power-of-attorney by Landlord. Upon such attornment, this Lease shall continue
in effect as a direct lease between such successor landlord and Tenant upon and
subject to all of the provisions of this Lease.

        13.3 ESTOPPEL CERTIFICATES: Within fifteen (15) days after written
notice from Landlord, Tenant shall execute and deliver to Landlord, in
recordable form, a certificate in the form of Exhibit "H" stating (i) that this
Lease is unmodified and in effect, or in effect as amended, and stating all
amendments; (ii) the amount of Base Rent; (iii) the date to which Base Rent has
been paid in advance; (iv) the amount of any security deposit, prepaid rent or
other payment constituting rent which has been paid; (v) whether or not Tenant
or Landlord is in default under this Lease; and (vi) such other matters as
Landlord shall reasonably request. Tenant's failure to deliver such estoppel
certificate within such fifteen (15) day period shall be conclusive upon Tenant
for the benefit of Landlord, and any successor in interest to Landlord, that
this Lease is in effect and has not been amended except as may be represented by
Landlord, no rent has been paid more than thirty (30) days in advance and
neither Landlord nor Tenant is in default under this Lease. If Tenant fails to
deliver such estoppel certificate within such fifteen (15) day period, then
Tenant irrevocably appoints Landlord as its special attorney-in-fact to execute
and deliver such certificate to any third party. If Landlord executes documents
on behalf of Tenant pursuant to the special power-of-attorney, it shall be
deemed that Tenant has not waived any rights against Landlord by reason of the
contents of the estoppel certificate signed pursuant to the special
power-of-attorney by Landlord.

        13.4 NON-DISTURBANCE AGREEMENT: Landlord shall, within twenty (20) days
after the date of this Lease, obtain from Paul Revere Insurance Company and each

customers), the one that causes the other to become involved in such litigation
shall be liable to the other for reasonable attorneys' fees, court costs, and

recover from the losing party reasonable attorneys' fees, court costs, and other
expenses incurred by the prevailing party in such litigation.

        16.6 MERGER: A voluntary or other surrender of this Lease by Tenant, or

Lease shall not affect the interpretation of any provision thereof.

        16.12 PROVISIONS ARE COVENANTS AND CONDITIONS: All provisions, whether
covenants or conditions, to be performed or observed by Landlord and Tenant
shall be deemed to be both covenants and conditions.

be unenforceable or invalid for any reason, the remaining provisions of this
Lease shall be unaffected by such holding.

        16.15 LIMITATIONS ON LANDLORD'S LIABILITY: If Landlord is in default
under this Lease, and as a consequence, Tenant recovers a money judgment against
Landlord, such judgment shall be satisfied only out of the proceeds of sale
received upon execution of such judgment and levy against the right, title and
interest of Landlord in the Project, and out of rent or other income from the
Project receivable by Landlord or out of the consideration received by Landlord
from the sale or other disposition of or any part of Landlord's right, title and
interest in the Project, except for that portion of the judgment that

insurance, (ii) failure to refund Tenant's security deposit, (iii) fraudulent,
willful or intentional acts or misrepresentations, (iv) failure to apply

Section, neither Landlord nor the partners comprising Landlord (if any) shall be
personally liable for any deficiency.

Lease shall have no effect on its interpretation. Any exhibits referred to in

Landlord, any lender or buyer. Such financial statements shall include the past

steps necessary to ensure such confidentiality.

representative for examination or execution by Tenant does not constitute an

properly review a specific Change Order, and (ii) Tenant consents to the

Representatives and the Project free and harmless of any and all costs, claims,

                                   EXHIBIT D
<PAGE>

All defined terms in this Exhibit D shall have the same meaning as in the Lease.

I.      GENERAL

        A.      Pacific Corporate Park is designed to be a highly successful
                office building center. It is expected that tenant improvements
                and signage may represent a variety of design styles. PacCor
                Partners ("Landlord") intends to provide Tenant with reasonable
                latitude with this aspect of design. At the same time, Landlord
                will discourage tenant improvements and signage design that
                would conflict significantly with the general design of the
                buildings. These matters are more fully addressed in section VI
                of these Building/Tenant Improvement Standards For Pacific
                Corporate Park ("Building Standards").

                In providing the Building Standards, it is Landlord's intent to
                simplify the effort of Tenant in securing Landlord's approval of
                tenant improvements and/or alterations to be constructed by
                Tenant through a clear understanding of the responsibility of
                each party. The Building Standards are intended to aid Tenant in
                designing its improvements in a timely manner, with the least
                disruption to other tenants, Landlord, and Landlord's
                contractors and agents.

                In the event of any conflict between the Building Standards, the
                Office Lease (the "Lease"), and the Work Letter, the provisions
                of the Lease and Work Letter will govern.

II.     LANDLORD'S RESPONSIBILITIES

                Landlord accepts the responsibility of providing assistance to
                Tenant, Tenant's architects, engineers and other consultants,
                and to Tenant's contractors, subcontractors and suppliers
                (collectively "Tenant's Contractors") to complete their work in
                the shortest time. To this end, Landlord may stringently enforce
                the provisions of the Building Standards and any other
                reasonable rules of conduct for design and construction.

        B.      Other responsibilities of Landlord are as follows:

                1.      Make available to Tenant and Tenant's Representatives a
                        person designated by the Landlord to be responsible for
                        providing information, review of Tenant's drawings, to
                        have final approval authority for all submittals, and to
                        resolve disputes between tenants.

                2.      Meet with Tenant and Tenant's Representatives in a
                        preliminary meeting to clarify details of Tenant's
                        tenant improvement process.

                3.      Provide Tenant and Tenant's Representatives with copies
                        of Landlord's construction documentation reasonably
                        required by Tenant to design Tenant's tenant
                        improvements.

                4.      Define the improvements in the Premises provided by
                        Landlord.

                5.      When necessary, refer Tenant and Tenant's
                        Representatives to Landlord's engineering and design
                        agents.

                6.      Review Tenant's submittals in accordance with the time
                        periods set forth herein and specify any elements which
                        are disapproved.

                7.      Use Landlord's best effort to ensure that Tenant's Work
                        is not unreasonably affected by the work of other
                        tenants or their agents.

III.    TENANT'S RESPONSIBILITIES

        A.      "Tenant's Work" shall include all work in the Premises other
                than improvements provided by Landlord described in Section IV

        B.      Tenant shall review Landlord's construction documentation,
                inspect the Premises, and promptly indicate any deficiencies of
                work to be completed by Landlord.

        C.      Tenant and Tenant's Representatives are responsible for
                requesting additional documentation or clarifications from
                Landlord if they feel that construction documentation provided
                by Landlord is inadequate or incomplete.

        D.      Tenant shall be thoroughly familiar with all aspects of the
                Lease applicable to Tenant's Work and the contents of these
                Building Standards.

        E.      Tenant shall be aware of the improvements provided by Landlord
                ("Landlord's Work").

        F.      Tenant shall select qualified and professional persons to act as
                design consultants and as Tenant's Contractors.

        G.      Tenant shall ensure that Tenant's design consultants and
                Tenant's Contractors are familiar with and comply with the
                contents of these Building Standards, applicable provisions of
                the Lease, and all City, County, State, and other governmental
                ordinances, rule, regulations, and codes pertaining to Tenant's
                work.

        H.      Tenant shall insure that the contractors engaged by Tenant to
                perform Tenant's Work shall be bondable and licensed in the
                State of California. The selection of such firm(s) are in the
                discretion of Tenant, subject to the reasonable approval of
                Landlord. By approving Tenant's Contractors, Landlord assumes no
                liability for the work completed by, or other obligations of,
                Tenant's Contractors.

        I.      Tenant shall ensure the cooperation of Tenant's Representatives
                with Landlord and Landlord's agents and other Tenants and their
                agents while at Pacific Corporate Park.

        J.      Tenant shall ensure that all submittals and resubmittals of
                Tenant's plans and specifications are made properly and in
                accordance with the timetables set forth in Section VIII of
                these Building Standards. After Landlord's approval of Tenant's
                plans and specifications, such drawings shall become
                "Construction Documents".

        K.      Tenant shall ensure that Construction Documents are in a
                condition that reasonably illustrate the design intent to
                construct and maintain the Premises. Tenant shall, upon request,
                provide Landlord with a color board of finishes set forth in the
                Construction Documents.

        L.      Tenant shall obtain and transmit to Landlord prior to
                commencement of Tenant's Work copies of all permits with respect
                to Tenant's Work required by the City, County of San Diego,
                and/or any utility service.

        M.      If required by Landlord in its sole discretion, Tenant or
                Tenant's Contractors shall furnish a bond or other security in
                form satisfactory to Landlord covering the prompt and faithful
                performance of Tenant's Work in an amount equal to one hundred
                twenty-five percent (125%) of the cost thereof.

        N.      Tenant shall not allow the Premises to be occupied until
                Tenant's sprinkler system has been inspected, approved and put
                into operation, and Tenant has received a Certificate of
                Occupancy from the Building Department of the City of San Diego.
                Tenant shall deliver to Landlord the Original Certificate of
                Occupancy immediately upon receipt from the City of San Diego.

        O.      Tenant and Tenant's Contractors shall be responsible for the
                security of the Premises during the period of construction,
                including re-keying, if required, of Tenant's doors after
                completion of construction. Landlord shall have no liability for
                any loss or damage, including theft of building materials,
                equipment or supplies.

        P.      Tenant shall, within ten (10) working days after the completion
                of Tenant's Work, execute and file of record, or cause to be
                filed of record, a notice of completion with respect thereto in
                a form complying with the applicable provisions of the
                California Civil Code specifying the names of Tenant's
                Contractors and the location of the work done. Tenant shall
                furnish to Landlord a conformed copy thereof after recordation.

        Q.      Tenant shall ensure that Tenant's Contractors exercise caution
                in matters relating to public safety and to prevent damage to
                the Common Areas and other leased areas. Tenant shall be
                responsible for any damage or liability occurring by reason of
                the acts or omissions of Tenant's Contractors.

        R.      Tenant shall require that Tenant's Contractors and other
                Representatives cause all supplies, materials, equipment, or
                trash being delivered to or removed from the Premises across the
                Common Areas or within the elevators, which requires the use of
                dollies or hand trucks, to be transported on dollies or hand
                trucks with soft rubber tires.

                        this limit.

                2.      Columns on the interior or on the periphery of the

                        Design Criteria set forth in Section VI hereof as
                        follows:

                        Electrical      Paragraph D
                        Plumbing        Paragraph E

                        Sprinklers      Paragraph G

                8.      Tenant agrees that Tenant's acceptance of the Premises
                        after completion of Landlord's Work shall constitute
                        Tenant's approval of same, except for any deficiencies
                        which Tenant has advised Landlord in writing within ten
                        (10) business days of the time when Tenant accepts the
                        Premises. Except as described in such notice, Tenant

                        right to claim or bring an action of any kind, direct or
                        indirect, latent or patent, against Landlord arising out
                        of the condition of the Premises, appurtenances thereto,
                        the improvements therein or the equipment therein, and
                        Landlord shall have no liability therefor.
                        Notwithstanding the foregoing, Landlord shall warrant
                        the Premises against defects in workmanship in
                        connection with Landlord's Work for a period of one (1)
                        year from the date of completion thereof. Tenant shall
                        not refuse to accept delivery of the Premises as a
                        result of a "punchlist," unless any such defect
                        unreasonably precludes Tenant's Contractors from
                        proceeding with Tenant's Work.

                9.      The work to be done by Landlord in satisfying its
                        obligation to construct the Premises shall be limited
                        only to those improvements described in this Section IV
                        hereof unless agreed by Landlord in writing.

                        and approval, subject to the Lease and Exhibit L. Tenant
                        shall not proceed with the fabrication or installation
                        of signage without the prior written approval by
                        Landlord of Tenant's final sign plans, which approval

                construction contracts prior to the commencement of Tenant's
                Work. Landlord's review of Tenant's contracts in no way implies
                Landlord's approval of such contracts, Tenant's Construction
                Documents, or that the contracts properly reflect the
                requirements of these Building Standards.

        B.      Tenant's Contractors shall construct Tenant's Work in accordance
                with Tenant's Construction Documents which have been approved by
                Landlord and must comply with all City, County, State and
                governmental ordinances, rule, regulations and codes relating
                thereto. If the Premises have not been constructed in accordance
                with approved Tenant's Construction Documents, Landlord may
                refuse to permit Tenant to open the Premises for business until
                the Premises do so comply, but Tenant shall not be excused from
                the performance of all other obligations of Tenant under the
                Lease.

        C.      Tenant's Contractors shall construct the Premises in accordance
                with Tenant's Construction Documents as soon as practically

                agree to pursue Tenant's Work diligently to completion.

        D.      All work performed by Tenant or Tenant's Contractors shall be
                performed in a manner so as to avoid any labor dispute which
                results or could result in a stoppage or impairment of work,
                deliveries, or any other services in the Project. If there shall
                be any such stoppage or impairment or threat thereof as a result
                of any such labor dispute, Tenant shall immediately undertake
                such action as may be necessary to eliminate such dispute or
                potential dispute, including any of the following:

                1.      Remove all disputants from the job site until such time
                        as the labor dispute no longer exists;

                        event of a union jurisdictional dispute.

                the building permit from said agency. Tenant will pay for the
                plan check and building permit fees required on the permit

                permission from Tenant, Landlord, the City Building Department,

                being delivered to or removed from the Premises across the
                Common Areas or within the elevators, which requires the use of
                dollies or hand trucks, to be transported on dollies or hand
                trucks with soft rubber tires.

        S.      Tenant and Tenant's Contractors shall comply with all applicable

                agreed upon roofing contractor at Tenant's expense. Such
                penetration shall be subject to Landlord's approval as to
                construction details, size, configuration, location and support.

        W.      Tenant's Contractors shall obtain approval from Landlord prior
                to penetrating any floor slab. Landlord's approval shall not
                relieve Tenant from responsibility for damage to Landlord's Work
                and/or any other tenant's work because of penetration by Tenant.

        X.      In addition to the requirements of the Lease, and without any
                limitation thereof, Tenant's Contractors shall (i) comply with
                all governmental rules and regulations including applicable OSHA
                standards and (ii) carry worker's compensation and public
                liability insurance (including property damage), with limits, in
                form and issued by insurance companies approved in advance by
                Landlord. Landlord, Tenant, Tenant's Contractor and/or
                subcontractors procuring the insurance shall be named insured
                (or named as additional insured) in each policy of said
                liability insurance, which policy shall have a cross-liability
                endorsement or its equivalent. Certificates evidencing the
                foregoing insurance shall be delivered to Landlord before any
                work is commenced by Tenant's Contractors and before any
                equipment and/or materials are moved into the Building.

        Y.      Tenant's Contractors shall guarantee that portion of Tenant's
                Work for which they are responsible against any defects in
                workmanship and materials for a period of not less than one (1)
                year after the date of completion of Tenant's Work. This
                guarantee shall include, without limitation, all expenses and
                costs incurred in the repair or replacement of the structure of
                the Building or the Common Areas should the Building or Common
                Areas be damaged or affected by the defective work, or by the
                repair or replacement of such defective work. All such
                warranties or guarantees as to materials or workmanship with
                respect to Tenant's Work shall be contained in a written
                agreement between Tenant and Tenant's Contractors. Tenant shall
                require Tenant's Contractors to include such guarantees in each
                subcontract, and all such guarantees shall be so written so that
                same shall inure to the benefit of both Tenant and Landlord, as
                their respective interests may appear, and so that same may be
                directly enforced by Tenant or Landlord. Tenant shall provide
                Landlord with an assignment or other assurance necessary to
                perfect Landlord's right to enforce any such guarantee.

        AA.     Tenant shall be required to settle and/or bond against any
                mechanic's or materialman's liens, or other similar liens, filed
                against the Building as a result of Tenant's Work in accordance
                with the provisions relating to such liens in the Lease and the
                Work Letter. Except to the extent caused by the Landlord's
                negligence or wrongful failure to make payments required under
                this Lease or the Work Letter, Tenant shall reimburse Landlord
                in full and indemnify, defend, and hold Landlord harmless from
                and against any liability, cost or expense incurred by Landlord
                in connection with any such lien.

        BB.     Tenant's Contractors shall keep the exterior Common Areas in an
                absolutely clean and neat condition at all times. If Tenant's
                Contractors violate this regulation on more than one (1)
                occasion, or fail to immediately cure such default, Landlord may
                prohibit Tenant's Contractors from entering the Building.

        CC.     Tenant's Contractors shall use restrooms only for personal
                functions. Cleaning of tools or painting equipment will not be
                allowed. Any utility sinks will contain water supply, but may
                not be used for tool or painting equipment cleaning or other
                construction work,

        DD.     Tenant's Contractors shall provide Landlord with a key for

                of emergencies, and permit the construction of service lines by
                other tenants, which service lines have been approved by Tenant.

        B.      Tenant's Construction Documents:

                1.      After Landlord's approval of Tenant's preliminary design
                        drawings, and subject to Tenant's field measurement of
                        the Premises, Tenant shall, at Tenant's expense, submit
                        to Landlord for approval three (3) sets of plans and one
                        (1) set of reproducible plans of Tenant's Construction

                        elevations, interior partitions; trade fixtures;
                        reflected ceiling plan, including ceiling height(s);

                        plumbing, electrical, telephone, security and sprinkler
                        systems, including the details of the hookup of these
                        systems to Landlord's Work; and all other improvements
                        to be performed by Tenant as a part of Tenant's Work.

                        these Building Standards for each component addressed
                        therein.

                2.      Construction of the improvements specified on Tenant's
                        Construction Documents shall not commence until Tenant's
                        Construction Documents have been approved by Landlord in
                        writing.

                3.      If Tenant's Construction Documents are in conflict with
                        terms and conditions of these Building Standards, the
                        Building Standards shall control. If Landlord approves
                        Tenant's Construction Documents and there is a conflict
                        between the Building Standards and the Construction
                        Documents as approved, to the extent the conflict does
                        not affect health and safety or the structural integrity
                        of the Building, the Construction Documents shall
                        control.

                        arising by reason of any subsequent change, modification
                        or alteration of Tenant's Construction Documents, made
                        at the request of Landlord, shall be at the expense of
                        the Tenant. No changes, modifications or alterations
                        shall be made to Tenant's Construction Documents without
                        the prior written consent of Landlord.

                5.      Landlord's approval of Tenant's Construction Documents
                        or any work or installation made by Tenant shall not
                        constitute a warranty or representation by Landlord that
                        Tenant's drawings, work or installations comply with the
                        requirements of any applicable law, ordinance or
                        regulation, or are safe, sound, merchantable or fit for
                        the purpose intended. Landlord shall have no liability
                        to Tenant in the event Tenant is required to change its
                        drawings or Tenant's Work after the approval thereof by
                        Landlord on account of the failure of such drawings or
                        Tenant's Work to meet applicable governmental
                        requirements or in the event that such drawings or
                        Tenant's Work, directly or indirectly, are defective or
                        cause injury to persons or property.

                        within thirty (30) days after completion or Tenant's
                        Work. If any clarifications or additions to the as-built
                        plans and specifications are required by Landlord,
                        Tenant shall cause such revisions to be completed within
                        thirty (30) days after request therefor.

Attn: Terry Arnett

Re: Pacific Corporate Park
    5930 and 5935 Cornerstone Court
    HVAC System

Dear Terry:

The subject buildings are serviced by a "Tri-Water" water source heat pump
system. The central plant, which houses a separate cooling tower, boiler and
recirculating pump for each building, is located in the parking area north of
building A. The condenser water is piped underground to each building and
connected to the fire sprinkler system which is routed throughout both
buildings. The individual water source heat pumps are then connected to the fire
sprinkler piping as a part of the tenant improvement.

The cooling towers installed are rated @ 350 GMP which would provide the
equivalent of approximately 140 tons of air conditioning capability for each
building. There is a 4 wire energy management loop that is routed from the
central plant to each building for connection to future tenant Water Source Heat
Pump ("WSHP") units. This allows the tenant to communicate with the central
plant to provide after hours cooling.

As part of the tenant improvement buildout, the following should be utilized as
guidelines for a minimum standard:

        1. Suspend WSHP units above the ceiling utilizing 1 in. spring isolation
for vibration and sound attenuation.

        2. Type L copper piping with hard solder should be utilized for the
condenser water piping to the individual WSHP units. Automatic flow controls are
required for each unit.

        3. The return air must be ducted and both supply and return ducts must
be insulated.

        4 Rigid duct to be utilized with flex duct on the last 7 ft. only.

                                    EXHIBIT F
<PAGE>

        5. Check valves must be installed on the condenser piping to the
individual WSHP units.

        6. Duct shall be sized at .1 in. pressure drop per 100 ft. of duct.

        7. Perimeter and interior zones shall not be combined.

        8. WSHP units shall be equivalent to Carrier, Trane or AAF.

        9. Outside air shall be provided @ 20 CFM/person.

Should you have any additional questions or comments, please do not hesitate to
call.

Sincerely,

of which are hereby acknowledged, the parties agree as follows:

        1. Lender agrees that:

                (a) Unless Tenant is in material breach of the Lease, Tenant
shall not be named or joined as a party defendant or otherwise in any lawsuit,
action or proceeding under the Deed of Trust or to enforce any rights of Lender
under the Deed of Trust or under any note or other obligation secured thereby;

                (b) So long as Tenant is not in default (beyond any period given
Tenant to cure such default) in the payments of rent or in the performance of
any of the terms, covenants or conditions of the Lease on Tenant's part to be

                                   ARTICLE IV

                            COVENANT FOR ASSESSMENTS

            4.01 Creation of Liens: The Developer, for each Lot owned, hereby
covenants, and each Owner of a Lot by acceptance of a deed therefor, whether or
not it shall be so expressed in such deed, is deemed to covenant and agrees to
pay to the Association: (i) Regular Assessments, (ii) Special Assessments, and
(iii) Capital Improvement Assessments, such Assessments to be established and
collected as provided herein. The Regular, Special and Capital Improvement
Assessments, together with interest, cost, penalties and reasonable attorney's
fees, shall be a charge on the Lot and shall be a continuing lien upon the Lot
against which each such Assessment is made. Each such Assessment, together with
interest, costs, penalties and reasonable attorney's fees, shall also be the
personal obligation of the person who was the Owner of such Lot at the time when
the Assessment fell due.

            4.02 Purpose of Assessments: The Assessments levied by the
Association shall be used exclusively for the purpose of promoting the health,
safety and welfare of the Members of the Association, to provide funds for the
Association to carry out its duties and obligations and, in particular, for the
improvement, landscaping and maintenance of the Association Maintenance Area and
other services and facilities devoted to this purpose, if any.

            4.03 Regular Assessments: The amount of Regular Assessments for a
fiscal year of the Association shall be determined by the Board of Directors of
the Association pursuant to the Articles of Incorporation and Bylaws of said
Association after giving duo consideration to the current maintenance costs and
future needs, including the buildup of reserves for working capital and
contingencies, of the Association. The Board of Directors of the Association
shall fix the, amount of Regular Assessment against each Lot for each fiscal
year at least thirty (30) days in advance of such year. Written notice of the
Regular Assessments shall be sent to every Owner subject thereto at least
fifteen (15) days prior to each fiscal year of the Association. The Regular
Assessments shall be paid in monthly installments.

            4.04 Special Assessments: Each Owner shall be liable to the
Association by way of Special Assessment for any damages to the Association
Maintenance Area or to any of the equipment or improvements thereon which may be
sustained

                                       8
<PAGE>
 by reason of the negligence or willful misconduct of said Owner or of his
employees, agents, guests or invitees, both minor and adult. Any expense
incurred by the Association in repairing such damage, together with costs and
attorneys' fees, shall be a debt of the Owner causing the same, and the Board
may specifically assess, by way of Special Assessment, said Owner for the amount
thereof to the extant that any such damage shall not be covered by a policy of
insurance. The Board may also levy Special Assessments: (i) to reimburse the
Association for steps taken pursuant to Sections 6.07 or 10.01 of this
Declaration; (ii) for Owners who are specifically found to be excessive users of
the services or facilities furnished or provided by the Association, including,
but not limited to, trash removal or parking facilities, or (iii) for steps
taken by the Association to remedy any wrongful violation of this Declaration.

            4.05 Capital Improvement Assessments: In addition to the Regular and
Special Assessments, the Association may levy in any calendar year, a Capital
Improvement Assessment applicable to that year only, provided that any such
Assessment shall have the approval by vote or written consent of Members
entitled to exercise not less than two-thirds (2/3) of the voting power of the
membership of the Association.

            The Board of Directors shall fix the amount of all Capital
Improvements Assessments at least thirty (30) days in advance of the date such
Assessments shall become due and shall give written notice at least fifteen (15)
days in advance of the date such Assessments shall become due to each Owner
subject thereto.

            4.06 Uniform Rate of Collection: The Regular and Capital Improvement
Assessments may be combined and collected on a monthly basis and shall be fixed
at a uniform formula rate for all Lots based upon the Net Useable Square Footage
of each Lot. Fixing Assessments at a uniform formula rate for all Lots does not
apply with respect to Special Assessments.

            4.07 Date of Commencement of Regular Assessments: The Regular
Assessments shall commence as to all Lots on the first day of the month
following the close of escrow for the first conveyance by Developer of any Lot
to any Class A Member of the Association.

            4.08 Certificate of Payment: The Association shall, upon demand,
furnish to any Owner liable for any Assessment, a certificate in writing signed
by an officer of the Association, setting forth whether the Regular and Special
and Capital Improvement Assessments on that Owner's Lot have been paid, and the
amount of the delinquency, if any. A reasonable charge may be made by the Board
for the issuance of these certificates. Such certificate shall be conclusive
evidence of payment of any Assessment therein stated to have been paid.

            4.09 Exempt Property: A11 properties dedicated to and accepted by a
local public authority shall be exempt from assessments.

            4.10 Waiver of Use: No Member may exempt himself by any means
whatsoever from personal liability for assessments duly levied by the
Association, nor release the Lot owned by him from the liens and charges
thereof, by abandonment of his Lot or otherwise.

                                    ARTICLE V

                            NONPAYMENT OP ASSESSMENTS

            5.01 Delinquency: Any Assessment which is not paid when due shall be
delinquent. With respect to each Assessment not paid within fifteen (15) days
after the due date, the Association may, at its election, require the Owner to
pay a "late charge" in a sum to be determined by the Association, but not to
exceed ten percent (10%) of the amount of the delinquent Assessment per each
delinquent Assessment. If any such Assessment is not paid within thirty (30)
days after the delinquency date, the Assessment shall bear interest from the
date of delinquency at the maximum rate permitted by law, and the Association
may, at its option, bring an action at law against the Owner personally
obligated to pay the same, or upon compliance with the notice provisions set
forth in Section 5.02 hereof, to foreclose the lien (provided for in Section
4.01 hereof) against the Lot, and there shall be added to the amount of such
Assessment the late charge, the costs of preparing and filing the complaint in
such action, and in the event a judgment is obtained, such judgment shall
include interest and reasonable attorneys' fees, together with the costs of
action. Each Owner vests in the Association or its assigns, the right and power
to bring all actions at law or lien foreclosure against such Owner to other
Owners for the collection of such delinquent Assessments.

            5.02 Notice of Lien: No action shall be brought to foreclose said
Assessment lien or to proceed under the power of sale herein provided until
thirty (30) days from the date a notice of claim of lien is deposited in the
United States mail, certified or registered, postage prepaid, to the Owner of
said Lot, and a copy thereof is recorded by the Association in the Office of the
San Diego County Recorder; said notice of claim must recite a good and
sufficient legal description of any such Lot, the Owner or reputed Owner
thereof, the amount claimed (which shall include interest, reasonable attorneys'
fees and expenses of collection incurred in connection with the debt secured
by said lien and late charges as specified above), and the name and address of
the claimant.

            5.03 Foreclosure Sale: Any such sale provided for above is to be
conducted in accordance with provisions of the Civil Code of the State of
California, as it may hereafter be modified or amended, applicable to the
exercise of powers of sale in mortgages and deeds of trust, or in any other
manner permitted or provided by law. The Association, through its duly
authorized agents, shall have the right to bid on the Lot at foreclosure sale,
and to acquire and hold, mortgage and convey the same.

<PAGE>

            5.04 Curing of Default: Upon the timely payment or other
satisfaction of (a) all delinquent Assessments specified in the notice of claim
of lien, (b) all other Assessments which have become due and payable with
respect to the Lot as to which such notice of claim of lien was recorded, and
(c) interest, late charges, attorneys` fees and other costs of collection
pursuant to this Declaration which have accrued, officers of the Association or
any other persons designated by the Board are hereby authorized to file or
record, as the case may be, an appropriate release of such notice, upon payment
by the defaulting Owner of an amount, to be determined by the Association, to
cover the costs of preparing and filing or recording such release.

            5.05 Cumulative Remedies: The lien and the rights to foreclosure and
Sale thereunder shall be in addition to and not in substitution for all other
rights and remedies which the Association and its assigns may have hereunder and
by law, including a suit to recover a money judgment for unpaid Assessments, as
provided above.

            5.06 Subordination of Assessment Liens: If any Lot subject to a
monetary lien created by any provision hereof shall be subject to the lien of a
deed of trust: (a) the foreclosure of any lien created by anything set forth in
this Declaration shall not operate to affect or impair the lien of such deed of
trust, and (b) the foreclosure of the lien of died of trust or the acceptance of
a deed in lieu of foreclosure of the deed of trust shall not operate to affect
or impair the lien hereof, except that the lien hereof for said charges as shall
have accrued up to the foreclosure or the acceptance of the deed in lieu of
foreclosure shall be subordinate to the lien of the deed of trust, with the
foreclosure purchaser or deed-in-lieu grantee taking title free of the lien
hereof for all said charges that have accrued up to the time of the foreclosure
or deed given in lieu of foreclosure, but subject to the lien hereof for all
said charges that shall accrue subsequent to the foreclosure or deed given in
lieu of foreclosure.

                              ARCHITECTURAL CONTROL

            6.01 Architectural Committee: There shall be an Architectural
Committee consisting of three (3) persons to be appointed by the Developer.
Except as otherwise provided herein, the members of the Architectural Committee
shall be subject to removal by the Developer at any time, with or without cause.
All vacancies on the Architectural Committee shall be filled by appointment by
the Developer. In the event of failure of the Developer to appoint such
Committee or to fill any vacancies therein, the Board shall have the right by
written document to appoint the members of the Architectural Committee or to
fill any vacancies. The Developer shall surrender and the Board shall assume the
right to appoint and remove the members of the Architectural Committee on the
date that Developer no longer owns at least one (1) Undeveloped Lot, provided
that the Developer shall, at its election, be entitled at all times to appoint
at

                                       11
<PAGE>

least one (1) person to the Architectural Committee, whether or not the
Developer is an Owner of a Lot. The Architectural Committee shall act by
majority vote of its members, but a majority of the Architectural Committee may
designate a representative to act for it.

            6.02 Promulgation of Guidelines: The Architectural Committee may
promulgate, from time to time, Guidelines setting forth the procedure for
submission and approval of and the form and content of Submittals for the
erection, construction, installation or alteration of Improvements, including
Landscape Improvements. These rules and regulations shall be promulgated to
assist Members in the submission of plans and specifications. In promulgating
and changing Guidelines, the Architectural Committee shall apply standards
consistent with the Government Regulations and the purpose of this Declaration.

            6.03 Plan Review: No Improvement of any nature whatsoever
(including, but not limited to, any alteration or addition to any Improvements
existing from time to time) shall be constructed, installed, assembled,
maintained or permitted to remain on any Lot until plans and specifications for
such Improvement (the "Submittals") shall have been approved in writing by the
Architectural Committee. All Submittals shall be prepared by an architect and/or
engineer, licensed to practice in the State of California, and shall be
submitted in writing over the signature of the Owner or his authorized agent.
Each Submittal shall conform to the Guidelines and any restrictions contained in
the deed pursuant to which the Developer first conveyed title to the Lot for
which the Submittal is made. Three (3) copies of each Submittal are required.

            6.04 Approvals: The Architectural Committee shall base its approval
or disapproval of any Submittal on, among other things, the adequacy of site
dimensions; the adequacy of structural design; the conformity and harmony of
external design with the neighboring structures; the affect of location and use
of improvements on neighboring sites, operations and uses; the relation of the
topography, grade and finished ground elevation of the site being improved to
that of the neighboring sites; the proper facing of elevations with respect to
nearby streets; and the conformity of the Submittal to the Government
Regulations and the purpose and general plan and intent of this Declaration. The
Committee shall not arbitrarily or unreasonably withhold its approval of such
Submittal. If the Architectural Committee fails either to approve or to
disapprove any Submittal within sixty (60) days after the same has been
submitted to and received by the Architectural Committee, it shall be
conclusively presumed that the Architectural Committee has approved the
Submittal, provided that the Improvements discussed in the Submittal are in
accord with the Government Regulations. Notwithstanding anything herein to the
contrary, approval by the Architectural Committee is not exclusive and all plans
and specifications required to be approved by the City of San Diego, whether
through the building permit process or otherwise, shall be so approved prior to
the commencement of construction.

<PAGE>

            6.05 Variances: Where circumstances, such as topography, location of
lot lines, location of trees, or other matters require, the Architectural
Committee may allow reasonable variances as to any of the Restrictions contained
in this Declaration and under the jurisdiction of the Architectural Committee,
on such terms and conditions as it shall require; provided, however, that all
such variances shall be in keeping with the provisions of the Government
Regulations and the purpose of this Declaration.

            6.06 Construction: Upon receipt of approval from the Architectural
Committee pursuant to this Section, the Owner to whom the same is given shall,
as soon as practicable, satisfy all conditions thereof and diligently proceed
with the commencement and completion of all approved construction and
alterations. In all cases, work shall be substantially completed within
twenty-four (24) months from the date of such approval. If there is a failure to
comply with this Section, then the approval given pursuant to this Section shall
be deemed revolted unless the Architectural Committee, upon request made prior
to the expiration of said twenty-four (24) month period, extends the time for
completing the work.

            6.07 Certificates of Compliance: Upon completion of construction or
installation of any Improvements, the Owner shall supply the Architectural
Committee with a Notice of Completion from a duly licensed or registered
architect certifying that the Improvements as constructed or installed are in
compliance with the Submittal previously approved by the Architectural
Committee. In the case of work involving Landscape Improvements, a separate
Notice of Completion pertaining to the Landscape Improvements shall be filed by
a landscape architect. If the Architectural Committee determines that the
Improvements are not in compliance with the previously approved Submittals, it
shall notify the Owner in writing of such non-compliance within ninety (90) days
after the receipt of the Notice of Completion. If the Architectural committee
determines that the Owner has not remedied the non-compliance within thirty (30)
days from the date of the notice of non-compliance, the Architectural Committee
shall notify the Association of the non-compliance. The Association shall
thereafter have the right to take such steps to remedy the non-compliance as the
Board in its sole discretion deems reasonable and necessary.

            Unless the Architectural Committee determines within (90) days that
the Improvements are not in compliance with the previously approved Submittal,
the Notice of Completion shall be deemed accepted by the Architectural
Committee.

            6.08 Architectural Fee: The Architectural Committee may charge and
collect a reasonable fee for the examination of any Submittals. The amount of
such fee shall not exceed the cost of making such examination, including the
cost of any architect's or engineer's fees incurred in connection therewith.

            6.09 Waiver: The approval of the Architectural Committee of any
Submittals for any work done or proposed.

                                       13
<PAGE>

or for any other matter requiring the approval of said Committee, shall not be
deemed to constitute a waiver of any right to withhold approval of any similar
plans, drawings, specifications or other matters subsequently submitted for
approval.

            6.10 Nonliability for Decisions: Neither the Developer, the
Association, nor the Architectural Committee or the members thereof shall be
liable to anyone submitting plans to them for approval or to any Owner or lessee
of land affected by this Declaration, by reason of mistake in judgment,
negligence or nonfeasance arising out of or in connection with the approval or
disapproval or failure to approve any such plans. Approval or disapproval of any
Submittal by the Architectural Committee shall not constitute a determination as
to the structural integrity, adequacy or fitness of the Improvements
contemplated by such submittal, and neither the Developer, the Association, nor
the Architectural Committee or the members thereof shall be liable to anyone
submitting plans for approval or to any Owner or lessee of land affected by this
Declaration in the event the Improvements contemplated by such Submittal are
inadequate or unfit. Every person who submits plans to the Architectural
Committee for approval agrees, by submission of such plans, and every Owner or
lessee of any of the property agrees, by acquiring title thereto or interest
therein, that he will not bring any action or suit against the Developer, the
Association, the Architectural Committee or any members thereof to recover any
damages for any of the foregoing.

            6.11 General: The members of the Architectural Committee shall not
be entitled to any compensation for services performed pursuant to this
Declaration; however, any architect, engineer or similar party employed by the
Architectural Committee to assist in the review of Submittals shall be entitled
to a fee.

            6.12 Disclosure and Waiver of Conflict of Interest: The Developer
hereby discloses the following:

            (a) The members of the Architectural Committee may be affiliated
with and employed by the Developer.

            (b) Should the Developer submit plans and specifications to the
Architectural Committee, the members of the Architectural Committee appointed by
the Board may be in a conflict of interest in rendering their decisions.

            Neither the Developer nor any member of the Architectural Committee
shall have any liability to any Owner or other person by reason of decision
which may benefit the Developer rendered in good faith by the Architectural
Committee or any member thereof while in a conflict of interest, and each Owner
hereby waives any claim of liability against the Developer, the Architectural
Committee, or any member thereof based on such conflict of interest. Nothing
herein stated is intended to limit the application or meaning of Section 6.10
above or Section 1.03 below.

1. That the Planning Director adopts as the Findings of the Planning Director
those written Findings dated February 18, 1986, a copy of which is attached
hereto and by this reference incorporated herein.

No. 85-O830, a copy of which is attached hereto and made a part hereof.

FINDINGS

1. The proposed project will fulfill a need and will not adversely affect the
neighborhood, the General Plan, or the Community Plan. The Mire Mesa Community
Plan designates the area for light-industrial uses. The project is a phased
industrial-office development, which is consistent with this land use

<PAGE>
                                     O 1946

designation. The development would be compatible with surrounding land uses,
proposed and existing.

2. The proposed project, because of conditions that have been applied to it,
will not be detrimental to the health, safety and general welfare of persons
residing or working in the area, and will not adversely affect other property in
the vicinity. Land use limitations have been placed on specific lots in the
industrial development. This will ensure that traffic generated by the project
will not exceed the carrying capacity of the community transportation system.

3. The proposed protect will comply with all the relevant regulations in the
Municipal Code. The development meets all of the requirements of the Planned
Industrial Development Ordinance.

Road will be landscaped with ornamental naturalized groundcover which will
visually connect the roadway area with the adjacent native landscaped slopes.
The slopes and the transition area will be planted with trees which will provide
additional blending with the surrounding topography. The size of plant material
used will range from box size trees (e.g. California sycamore) and container
size groundcover in the transition area, to hydroseeded shrubs and container
size trees
