                            2000 CASH BONUS PLAN FOR:
                                   CEO AND COO

         Two (2) individuals will be eligible to participate in this plan.

1.       BONUS AWARD AMOUNT. The CEO's and COO's cash incentive compensation
         will be based on a percent of the Company's consolidated pretax income
         before accrual for bonuses; in the year 2000, these bonus awards will
         be 3% and 3%, respectively -- except in the event that the Company's
         performance is less than 50% of the Company's business plan, in which
         case they will be discretionary. These bonus awards are subject to
         annual review by the Compensation Committee of the Board of Directors.

         Participants will be notified annually through a participation letter
         of their eligibility to participate in the plan and their bonus
         opportunity.

2.       BONUS ELIGIBILITY AND PAY DATES. To be eligible to receive their
         respective cash bonus awards, each of the CEO and COO must be employed
         on BOTH of the following dates for the applicable bonus: (a) 12-31 year
         end, AND (b) bonus payment date.

         The CEO's and COO's bonuses will be paid over two (2) years after
         completion of the Company's applicable annual audits, with 75% paid the
         first year, and 25% paid the second year. Bonuses for the prior year's
         results will be payable after approximately the third week in February
         each year, when the audit typically is concluded. The balance payable
         in the second year will be forfeited if the CEO's or COO's employment
         at the Company is terminated for any reason other than retirement,
         death or disability.

3.       FACTORS THAT MAY AFFECT BONUS AMOUNT PAID. The Compensation Committee
         of the Board of Directors retains the discretion to increase or reduce
         awards in the event of depressed business years or in the event of
         extraordinary or substandard performance of an individual, which may be
         made on the basis of either objective or subjective criteria.

         All bonus awards will be prorated downward if the sum of all calculated
         awards exceeds 20% of the Company's consolidated pretax income before
         bonuses. The proration factor is equal to 20% of pretax income for the
         Company divided by the sum of all calculated awards from all plans.

         in this plan.

1.       BONUS AWARD AMOUNT. Division Presidents' cash incentive compensation
         will be based on Division performance, as compared to the Division's
         2000 Business Plan:

         a.       If Division performance is 100% or more of the Division's 2000
                  Business Plan, the bonus amount will be the greater of: 3% of
                  Division pretax, pre-bonus annual income, OR 100% of salary.

         b.       If Division performance is 50% to 99% of the Division's 2000
                  Business Plan, the bonus amount will be the greater of: 3% of
                  Division pretax, pre-bonus annual income, OR the % of annual
                  salary that corresponds to % of Division business plan
                  achieved (i.e., if performance = 75% of plan, bonus = 75% of
                  annual salary).

         c.       If Division performance is less than 50% of the Division's
                  2000 Business Plan, the bonus amount will be discretionary.

         Participants will be notified annually through a participation letter
         of their eligibility to participate in the plan and their bonus
         opportunity.

2.       BONUS ELIGIBILITY AND PAY DATES. To be eligible to receive any cash
         bonus award, Division Presidents must be employed on BOTH of the
         following dates for the applicable bonus: (a) 12-31 year end, AND (b)
         bonus payment date.

         Division Presidents' bonuses will be paid over two (2) years after
         completion of the Company's applicable annual audits, with 75% paid the
         first year, and 25% paid the second year. Bonuses for the prior year's
         results will be payable after approximately the third week in February
         each year, when the audit typically is concluded. The balance payable
         in the second year will be forfeited if the Division President's
         employment at the Company is terminated for any reason other than
         retirement, death or disability.

3.       FACTORS THAT MAY AFFECT BONUS AMOUNT PAID. The Board of Directors, CEO
         and COO retain the discretion to increase or reduce awards in the event
         of depressed business years or in the event of extraordinary or
         substandard performance of an individual, which may be made on the
         basis of either objective or subjective criteria.

         All bonus awards will be prorated downward if the sum of all calculated
         awards exceeds 20% of the Company's consolidated pretax income before
         bonuses. The proration factor is equal to 20% of pretax income for the
         Company divided by the sum of all calculated awards from all plans.

                            2000 CASH BONUS PLAN FOR:
                       FIELD CONSTRUCTION SUPERINTENDENTS

         Superintendents and Assistant Superintendents acting in a
Superintendent capacity will be eligible to participate in this plan.

1.       BONUS AWARD AMOUNT. Superintendents' incentive compensation will be
         based on bonus targets set as a % of annual salary, ranging up to 25%,
         within the applicable ranges set forth below. These targets will be
         re-evaluated and reset annually, and assigned to each participant based
         upon: (a) management level and position impact within the Company; (b)
         competitive pay level for the position; (c) the total short-term
         compensation target for the position; and (d) the current salary of the
         incumbent in the position.

         Participants will be notified annually through a participation letter
         of their eligibility to participate in the plan and their bonus
         opportunity.

2.       BONUS ELIGIBILITY AND PAY DATES. To be eligible to receive any cash
         bonus award, Superintendents must be employed on BOTH of the following
         dates for the applicable bonus: (a) 12-31 year end, AND (b) bonus
         payment date.

         Superintendents' bonuses will be paid according to two separate
         schedules as follows:

         a.       50% of Award is based on Individual Performance and payable in
                  four (4) Quarterly Installments during the applicable year,
                  per individual quarterly goals.

         b.       50% of Award is based on Division Performance and payable
                  after completion of the applicable annual audit. Bonuses for
                  the prior year's results will be payable after approximately
                  the third week in February each year, when the audit typically
                  is concluded, per Division performance measured against its
                  business plan, as described below.

3.       FACTORS THAT MAY AFFECT BONUS AWARD AMOUNT. The Board of Directors, CEO
         and COO retain the discretion to increase or reduce awards in the event
         of depressed business years or in the event of extraordinary or
         substandard performance of an individual, which may be made on the
         basis of either objective or subjective criteria.

         All bonus awards will be prorated downward if the sum of all calculated
         awards exceeds 20% of the Company's consolidated pretax income before
         bonuses. The proration factor is equal to 20% of pretax income for the
         Company divided by the sum of all calculated awards from all plans.

4.       BONUS CALCULATION. Superintendents' bonus calculation will be based on
         TWO factors: 50% on Division Performance, and 50% on Individual
         Performance, as follows:

         a. 50% ON DIVISION PERFORMANCE. The applicable Division's actual
         performance will be measured against its business plan, as related to
         annually set measures of performance level designated as follows:
         Superior, Goal (Business Plan) and Threshold. Guidelines for relating
         actual performance to payout are as follows:

         (1)  The percentage difference of threshold from goal and superior
              from goal will vary depending upon specific circumstances
              affecting the performance of each operating division.

         (2)  Interpolate for performance between discrete points.

         b. 50% ON INDIVIDUAL PERFORMANCE. All individual performance awards
         (per results of individual Score Cards) will be subject to meeting the
         applicable Company/Division performance threshold of 50% of Business
         Plan. Assuming the business plan threshold is met, awards for
         performance on individual measures will vary with performance. Specific
         individual performance measures will be determined by each
         Superintendent's direct supervisor (similar to the examples which are
         shown below), and approved by the Division President:

Lessor's prior consent, but in compliance with all Applicable Law, use any
ordinary and customary materials reasonably required to be used by Lessee in the
normal course of Lessee's business permitted on the Premises, so long as such
use is not a Reportable Use and does not expose the Premises or neighboring
properties to any meaningful risk of contamination or damage or expose Lessor to
any liability therefore. In addition, Lessor may (but without any obligation to
do so) condition its consent to the use or presence of any Hazardous Substance,
activity or storage tank by Lessee upon Lessee's giving Lessor such additional
assurances as Lessor, in its reasonable discretion, deems necessary to protect
itself, the public, the Premises and the environment against damage,
contamination or injury and/or liability therefrom or therefore, including, but
not limited to, the installation (and removal on or before Lease expiration or
earlier termination) of reasonably necessary protective modifications to the

notice to Lessor of Lessee's commitment to pay for the repair of such damage
totally at Lessee's expense and without reimbursement from Lessor. Lessee shall
provide Lessor with the required funds or satisfactory assurance thereof within
thirty (30) days following Lessee's said commitment. In such event this Lease
shall continue in full force and effect, and Lessor shall proceed to make such
repairs as soon as reasonably possible and the required funds are available. If
Lessee does not give such notice and provide the kinds or assurance thereof
within the times specified above, this Lease shall terminate as of the date
specified in Lessor's notice of termination.

     9.4 TOTAL DESTRUCTION. Notwithstanding any other provision hereof, if a
Premises Total Destruction occurs (including any destruction required by any
authorized public authority), this Lease shall terminate on the date of such
Premises Total Destruction, whether or not the damage or destruction is an
Insured Loss or was caused by a negligent or willful act by Lessee. In the
event, however, that the damage or destruction was caused by Lessee, Lessor
shall have the right to recover Lessor's damages from Lessee except as released
and waived in Paragraph 8.6.

     9.5 DAMAGE NEAR END OF TERM. If at any time during the last six (6) months
of this Lease there is damage for which the cost to repair exceeds one (1)
month's Base Rent, whether or not an insured loss, Lessee or Lessor may, at its
option, terminate this Lease effective on the date of occurrence of such damage
by giving written notice to Lessee of Lessors election to do so within thirty
(30) days alter the date of occurrence of such damage. Provided, however, if
Lessee at that time has an exercisable option to extend this Lease or to
purchase the Premises, then Lessee may preserve this Lease by, within twenty
(20) days following the occurrence of the damage, or before the expiration of
the time provided in such option for its exercise, whichever is earlier
("Exercise Period"), (i) exercising such option and (if) providing Lessor with
any shortage in insurance proceeds for adequate assurance thereof) needed to
make the repairs. If Lessee duly exercises such option during said Exercise
Period and provides Lessor with funds (or adequate assurance thereof) to cover
any shortage in insurance proceeds, Lessor shall, at Lessor's expense repair
such damage as soon as reasonably possible and this Lease shall continue in full
force and effect. If Lessee fails to exercise such option and provide such funds
or assurance during said Exercise Period, then Lessor may at Lessor's option
terminate this Lease as of the occurrence of such damage by giving written
notice to Lessee of Lessor's election to do so within ten (10) days after the
expiration of the Exercise Period, notwithstanding any term or provision in the
grant of option to the contrary.

the Premises, the Base Rent, Real Property Taxes, insurance premiums, and other
charges, if any payable by Lessee hereunder for the period during which such
damage, its repair or the restoration continues shall be abated in proportion to
the degree to which Lessee's use of the Premises is impaired. Except for
abatement of Base Rent, Real Property Taxes, insurance premiums, and other
charges, if any, as aforesaid, all other obligations of Lessee hereunder shall
be performed by Lessee, and Lessee shall have no claim against Lessor for any
damage suffered by reason of any such repair or restoration.

     (b) If Lessor shall be obligated to repair or restore the Premises under
the provisions of this Paragraph 9 and shall not commence/in a substantial and
meaningful way, the repair or restoration of the Premises within forty-five (45)
days after such obligation shall accrue, Lessee may, at any time prior to the
commencement of such repair or restoration, give written notice to Lessor and to
any Lenders of which Lessee has actual notice of Lessee's election to terminate
this Lease on the date of such notice. "Commence" as used in this Paragraph
shall mean either the unconditional authorization of the preparation of the
required plans, or the beginning of the actual work on the Premises, whichever
first occurs.

     9.7 HAZARDOUS SUBSTANCE CONDITIONS. If a Hazardous Substance Condition
occurs, unless Lessee is legally responsible therefore (in which case Lessee
shall make the investigation and remediation thereof required by Applicable Law
and this Lease shall continue in full force and effect, but subject to Lessor's
rights under Paragraph 13) Lessor shall investigate and remediate such Hazardous
Substance Condition, if required, as soon as reasonably possible at Lessor's
expense. If a Hazardous Substance Condition occurs for which Lessee is not
legally responsible, there shall be abatement of Lessee's obligations under this
Lease to the same extent as provided in Paragraph 9.6(a) for a period of not to
exceed twelve months.

     9.8 TERMINATION-ADVANCE PAYMENTS. Upon termination of this Lease pursuant
to this Paragraph 9, an equitable adjustment shall be made concerning advance
Base Rent and any other advance payments made by Lessee to Lessor. Lessor shall,

been, or is not then required to be, used by Lessor under the terms of this
Lease.

     9.9 WAIVE STATUTES. Lessor and Lessee agree that the terms of this Lease
shall govern the effect of any damage to or destruction of the Premises with
respect to the termination of this Lease and hereby waive the provisions of any
present or future statute to the extent inconsistent herewith.

10.  REAL PROPERTY TAXES.

     10.1 (a) PAYMENT OF TAXES. Lessee shall pay the Real Property Taxes, as
defined in Paragraph 10.2, applicable to the Premises during the term of this
Lease. Subject to Paragraph 10.1(b), all such payments shall be made prior to
the delinquency date of the applicable installment. Lessee shall promptly
furnish Lessor with satisfactory evidence that such taxes have been paid. If any
such taxes to be paid by Lessee shall cover any period of time prior to or after
the expiration or earlier termination of the term hereof, Lessee's share of such
taxes shall be equitably prorated to cover only the period of time within the
tax fiscal year this Lease is in effect, and Lessor shall reimburse Lessee for
any overpayment after such proration. If Lessee shall fail to pay any Real
Property Taxes required by this Lease to be paid by Lessee. Lessor shall have
the right to pay the same, and Lessee shall reimburse Lessor therefore upon
demand.

     (b) ADVANCE PAYMENT. In order to insure payment when due and before
delinquency of any or all Real Property Taxes. Lessor reserves the right, at
Lessor's option, to estimate the current Real Property Taxes applicable to the
Premises, and to require such current year's Real Property Taxes to be paid in
advance to Lessor by Lessee, either: (i) in a lump sum amount equal to the
installment due, at least twenty (20) days prior to the applicable delinquency
date, or (ii) monthly in advance with the payment of the Base Rent. If Lessor
elects to require payment monthly in advance, the monthly payment shall be that
equal monthly amount which, over the number of months remaining before the month
in which the applicable tax installment would become delinquent (and without
interest thereon), would provide a fund large enough to fully discharge before
delinquency the estimated installment of taxes to be paid. When the actual
amount of the applicable tax bill is known, the amount of such equal monthly
advance payment shall be adjusted as required to provide the fund needed to pay
the applicable taxes before delinquency. If the amounts paid to Lessor by Lessee
under the provisions of this Paragraph are insufficient to discharge the
obligations of Lessee to pay such Real Property Taxes as the same become due,
Lessee shall pay to Lessor, upon Lessor's demand, such additional sums as are
necessary to pay such obligations. All moneys paid to Lessor under this
Paragraph may be intermingled with other moneys of Lessor and shall not bear
interest in the event of a Breach by Lessee in the performance of the
obligations of Lessee under this Lease, then any balance of funds paid to Lessor
under the provisions of this Paragraph may, subject to proration as provided in
Paragraph 10.1(a), at the option of Lessor, be treated as an additional Security
Deposit under Paragraph 5.

     10.2 DEFINITION OF "REAL PROPERTY TAXES." As used herein, the term "Real
Property Taxes" shall include any form of real estate tax or assessment,
general, special, ordinary or extraordinary, and any license fee, commercial
rental tax, improvement bond or bonds, levy or tax (other than inheritance,
personal income or estate taxes) imposed upon the Premises by any authority

government, or any school, agricultural, sanitary, fire, street, drainage or
other improvement district thereof, levied against any legal or equitable
interest of Lessor in the Premises or in the real property of which the Premises
are a part. Lessor's right to rent or other income therefrom, and/or Lessor's
business of leasing the Premises. The term "Real Property Taxes" shall also

imposed by reason of events occurring, or changes in applicable law taking
effect, during the term of this Lease, including but not limited to a change in
the ownership of the Premises or in the improvements thereon, the execution of
this Lease, or any modification, amendment or transfer thereof, and whether or
not contemplated by the Parties.

     10.3 JOINT ASSESSMENT. If the Premises are not separately assessed,
Lessee's liability shall be an equitable proportion of the Real Property Taxes
for all of the land and improvements included within the tax parcel assessed,
such proportion to be determined by Lessor from the respective valuations
assigned in the assessor's work sheets or such other information as may be
reasonably available. Lessors reasonable determination thereof, in good faith,
shall be conclusive.

     10.4 PERSONAL PROPERTY TAXES. Lessee shall pay prior to delinquency all
taxes assessed again. end levied upon Lessee Owned Alterations. Utility
Installations. Trade Fixtures, furnishings. equipment and all personal property
of Lessee contained in the Premises or elsewhere. When possible. Lessee shall

alter receipt of a written statement setting forth the taxes applicable to
Lessee's property or, at Lessor's option, as provided m Paragraph 10.1(b).

11. UTILITIES. Lessee shall pay for all water, gas, heat, light, power,
telephone, trash disposal and other utilities and services supplied to the
Premises, together with any taxes thereon. If any such services are not
separately metered to Lessee, Lessee shall pay a reasonable proportion, to be
determined by Lessor, of all charges jointly metered with other premises.

12.  ASSIGNMENT AND SUBLETTING.

     12.1 LESSOR'S CONSENT REQUIRED.

     (a) Lessee shall not voluntarily or by operation of law assign, transfer,
mortgage or otherwise transfer or encumber (collectively, "assignment") or
sublet all or any part of Lessee's interest in this a Lease or in the Premises
without Lessor's prior consent given under and subject to the terms of Paragraph
36. Lessor shall respond to requests for consent within ten (10) days, and any
refusal of consent shall by accompanied by a detailed written explanation
thereof.

     (b) A change in the control of Lessee shall constitute an assignment
requiring Lessor's consent. The transfer, on a cumulative basis, of 50% or more
of the voting control of Lessee shall constitute a change in control for this
purpose. See Addendum.

     (c) The involvement of Lessee or its assets in any transaction, or series
of transactions (by way of merger, sale, acquisition, financing, refinancing,
transfer, leveraged buy-out or otherwise), whether or not a formal assignment or
hypothecation of this Lease or Lessee's assets occurs, which results in a
reduction of the Net Worth of Lessee, as hereinafter defined, by an amount equal
to or less than twenty-five percent (25%) of such Net Worth of Lessee as it was
represented to Lessor at the time of the execution by Lessor of this Lease or at
the time of the most recent assignment to which Lessor has consented, or as it
exists immediately prior to said transaction or transactions constituting such
reduction, at whichever time said Net Worth of Lessee was or shall be considered
an assignment of this Lease by Lessee to which Lessor may reasonably withhold
its consent. "Net Worth of Lessee" for purposes of this Lease shall be the net
worth of Lessee (excluding any guaranties) established under generally accepted
accounting principles consistently applied.

     (d) An assignment or subletting of Lessee's interest in this Lease without
Lessor's specific prior written consent shall, at Lessor's option, be a Default
curable after notice per Paragraph 13.1(c). or a non-curable Breach without the
necessity of any notice and grace period. If Lessor elects to treat such
unconsented to assignment or subletting as a non-curable Breach, Lessor shall
have the right to either: (i) terminate this Lease, or (ii) upon thirty (30)
days written notice ("Lessor's Notice"), increase the monthly Base Rent to fair
market rental value or one hundred ten percent (110%) of the Base Rent then in
effect, whichever is greater. Pending determination of the new fair market
rental value, if disputed by Lessee, Lessee shall pay the amount set forth in
Lessor's Notice, with any overpayment credited against the next installment(s)
of Base Rent coming due, and any underpayment for the period retroactively to
the effective date of the adjustment being due and payable immediately upon the
determination thereof. Further, in the event of such Breach and market value
adjustment, (i) the purchase price of any option to purchase the Premises held
by Lessee shall be subject to similar adjustment to the then fair market value
(without the Lease being considered an encumbrance or any deduction for
depreciation or obsolescence. and considering the Premises at its highest and
best use and in good condition), or one hundred ten percent (110%) of the price
previously in effect, whichever is greater. (ii) any index-oriented rental or
price adjustment formulas contained in this Lease shall be adjusted to require
that the base index be determined with reference to the index applicable to the
time of such adjustment, and (iii) any fixed rental adjustments scheduled during
the remainder of the Lease term shall be increased in the same ratio as the new
market rental bears to the Base Rent in effect immediately prior to the market
value adjustment.

     12.2 TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

     (a) Regardless of Lessor's consent, any assignment or subletting shall not:
(i) be effective without the express written assumption by such assignee or
sublessee of the obligations of Lessee under this Lease. (ii) release Lessee of
any obligations hereunder. or (iii) alter the primary liability of Lessee for
the payment of Base Rent and other sums due Lessor hereunder or for the
performance of any other obligations to be performed by Lessee under this Lease.

     (b) Lessor may accept any rent or performance of Lessee's obligations from
any person other than Lessee pending approval or disapproval of an assignment.
Neither a delay in the approval or disapproval of such assignment nor the
acceptance of any rent or performance shall constitute a waiver or estoppel of
Lessor's right to exercise its remedies for the Default or Breach by Lessee of
any of the terms, covenants or conditions of this Lease.

     (c) The consent of Lessor to any assignment or subletting shall not
constitute a consent to any subsequent assignment or subletting by Lessee or to
any subsequent or successive assignment or subletting by the sublessee. However,
Lessor may consent to subsequent sublettings and assignments of the sublease or
any amendments or modifications thereto without notifying Lessee or anyone else
liable

<PAGE>   7

on the Lease or sublease and without obtaining their consent, and such action
shall not relieve such persons from liability under this Lease or sublease.

     (d) In the event of any Default or Breach of Lessee's obligations under
this Lease, Lessor may proceed directly against Lessee, any Guarantors or any
one else responsible for the performance of the Lessee's obligations under this
Lease, including the sublessee, without first exhausting Lessor's remedies
against any other person or entity responsible therefore to Lessor, or any
security held by Lessor or Lessee.

     (e) Each request for consent to an assignment or subletting shall be in
writing, accompanied by information relevant to Lessor's determination as to the
financial and operational responsibility and appropriateness of the proposed
assignee or sublessee, including but not limited to the intended use and/or
required modification of the Premises, if any, together with a non-refundable
deposit of $500, as reasonable consideration for Lessor's considering and
processing the request for consent. Lessee agrees to provide Lessor with such
other or additional information and/or documentation as may be reasonably
requested by Lessor.

     (f) Any assignee of, or sublessee under, this Lease shall, by reason of
accepting such assignment or entering into such sublease, be deemed, for the
benefit of Lessor, to have assumed and agreed to conform and comply with each
and every term, covenant, condition and obligation herein to be observed or
performed by Lessee during the term of said assignment or sublease, other than
such obligations as are contrary to or inconsistent with provisions of an
assignment or sublease to which Lessor has specifically consented in writing.

     12.3 ADDITIONAL TERMS AND CONDITIONS APPLICABLE TO SUBLETTING. The
following terms and conditions shall apply to any subletting by Lessee of all or
any part of the Premises and shall be deemed included in all subleases under
this Lease whether or not expressly incorporated therein:

     (a) Lessee hereby assigns and transfers to Lessor all of Lessee's interest
in all rentals and income arising from any sublease of all or a portion of the
Premises heretofore or hereafter made by Lessee, and Lessor may collect such
rent and income and apply same toward Lessee's obligations under this Lease;
provided, however, that until a Breach (as defined m Paragraph 13.1) shall occur
in the performance of Lessee's obligations under this Lease. Lessee may, except
as otherwise provided in this Lease, receive, collect and enjoy the rents
accruing under such sublease. Lessor shall not, by reason of this or any other
assignment of such sublease to Lessor, nor by reason of the collection of the
rents from a sublessee, be deemed liable to the sublessee for any failure of
Lessee to perform and comply with any of Lessee's obligations to such sublessee
under such sublease. Lessee hereby irrevocably authorizes and directs any such
sublessee, upon receipt of a written notice from Lessor stating that a Breach
exists in the performance of Lessee's obligations under this Lease, to pay to
Lessor the rents and other charges due and to become due under the sublease.
Sublessee shall rely upon any such statement and request from Lessor and shall
pay such rents and other charges to Lessor without any obligation or right to
inquire as to whether such Breach exists and notwithstanding any notice from or
claim from Lessee to the contrary. Lessee shall have no right or claim against
said sublessee, or, until the Breach has been cured, against Lessor, for any
such rents and other charges so paid by said sublessee to Lessor.

     (b) In the event of a Breach by Lessee in the performance of its
obligations under this Lease, Lessor, at its option and without any obligation
to do so, may require any sublessee to attorn to Lessor, in which event Lessor
shall undertake the obligations of the sublessor under such sublease from the
time of the exercise of said option to the expiration of such sublease;
provided, however, Lessor shall not be liable for any prepaid rents or security
deposit paid by such sublessee to such sublessor or for any other prior Defaults
or Breaches of such sublessor under such sublease.

     (c) Any matter or thing requiring the consent of the sublessor under a
sublease shall also require the consent of Lessor hereon.

     (d) No sublessee shall further assign or sublet all or any part of the
Premises without Lessor's prior written consent.

     (e) Lessor shall deliver a copy of any notice of Default or Breach by
Lessee to the sublessee, who shall have the right to cure the Default of Lessee
within the grace period, if any, specified in such notice. The sublessee shall
have a right of reimbursement and offset from and against Lessee for any such
Defaults cured by the sublessee.

13.  DEFAULT; BREACH; REMEDIES.

comply with or perform any of the terms, covenants, conditions or rules
applicable to a party under this Lease. A "Breach" is defined as the occurrence
of any one or more of the following Defaults, and, where a grace period for cure
after notice is specified herein, the failure by Lessee to cure such Default
prior to the expiration of the applicable grace period, and shall entitle Lessor
to pursue the remedies set forth in Paragraphs 13.2 and/or 13.3: (a) The
abandonment of the Premises accompanied by nonpayment of Base Rent for 14
consecutive days or longer. (b) Except as expressly otherwise provided in this
Lease, the failure by Lessee to make any payment of Base Rent or any other

Default by Lessee as to the terms, covenants, conditions or provisions of this
Lease, or of the rules adopted under Paragraph 10 hereof, that are to be
observed, complied with or performed by Lessee, other than those described in
subparagraphs (a), (b) or (c), above, where such Default continues for a period
of thirty (30) days after written notice thereof by or on behalf of Lessor to
Lessee: provided, however, that if the nature of Lessee's Default is such that
more than thirty (30) days are reasonably required for its cure, then it shall
not be deemed to be a Breach of this Lease by Lessee, if Lessee commences such
cure within said thirty (30) day period and thereafter diligently prosecutes
such cure to completion. (e) The occurrence of any of the following events: (i)
The making by Lessee of any general arrangement or assignment for the benefit of
creditors. (ii) Lessee's becoming a "debtor" as deleted in 11 U.S.C. Section 101

appointment of a trustee or receiver to take possession of substantially all of
Lessee's assets located at the Premises or of Lessee's interest in this Lease,
where possession is not restored to Lessee within sixty (60) days; or (iv) the
attachment, execution or other judicial seizure of substantially all of Lessee's
assets located at the Premises or of Lessee's interest in this Lease, where such
seizure is not discharged within sixty (60) days; provided, however, in the
event that any provision of this subparagraph (e) is contrary to any applicable
law, such provision shall be of no force or effect, and not affect the validity
of the remaining provisions. (f) The discovery by Lessor that any financial
statement given to Lessor by Lessee or any Guarantor of Lessee's obligations
hereunder was materially false. (g) If the performance of Lessee's obligations
under this Lease is guaranteed: (i) the death of a guarantor, (ii) the
termination of a guarantor's liability with respect to this Lease other than in
accordance with the terms of such guaranty, (iii) a guarantor's becoming
insolvent or the subject of a bankruptcy filing, (iv) a guarantor's refusal to
honor the guaranty, or (v) a guarantor's breach of its guaranty obligation on an
anticipatory breach basis, and Lessee's failure, within sixty (60) days
following written notice by or on behalf of Lessor to Lessee of any such event,
to provide Lessor with written alternative assurance or security, which, when
coupled with the then existing resources of Lessee, equals or exceeds the
combined financial resources of Lessee and the guarantors that existed at the
time of execution of this Lease, and such failure is a Breach.

     13.2 REMEDIES. If Lessee fails to perform any affirmative duty or
obligation of Lessee under this Lease and such failure is a Breach, Lessor may
at its option (but without obligation to do so), perform such duty or obligation
on Lessee's behalf including but not limited to the obtaining of reasonably
required bonds, insurance policies, or governmental licenses, permits or
approvals. The accrual and reasonable costs and expenses of any such performance
by Lessor shall be due and payable by Lessee to Lessor upon invoice therefore.
If any check given to Lessor by Lessee shall not be honored by the bank upon
which it is drawn, Lessor, at its option may require all future payments to be
made under this Lease by Lessee to be made only by cashier's check. In the event
of a Breach of this Lease by Lessee, as defined in Paragraph 13.1, with or
without further notice or demand,and without limiting Lessor in the exercise of
any right or remedy which Lessor may have by reason of such Breach, Lessor may:

<PAGE>   8

     (a) Terminate Lessee's right to possession of the Premises by any lawful
means, in which case this lease and the term hereof shall terminate and Lessee
shall immediately surrender possession of the Premises to Lessor. In such event
Lessor shall be entitled to recover from lessee: (i) the worth at the time of
the award of the unpaid rent which had been earned at the time of termination;
(ii) the worth at the time of award of the amount by which the unpaid rent which
would have been earned after termination until the time of award exceeds the
amount of such rental loss that the Lessee proves could have been reasonably
avoided; (iii) the worth at the time of award of the amount by which the unpaid
rent for the balance of the term after the time of award exceeds the amount of
such rental loss that the Lessee proves could be reasonably avoided; and (iv)
any other amount necessary to compensate Lessor for all the detriment
proximately caused by the Lessee's failure to perform its obligations under this
Lease or which in the ordinary course of things would be likely to result
therefrom, including but not limited to the cost of recovering possession of the
Premises, expenses of reletting, if allowed by law, reasonable attorneys' fees,
and that portion of the leasing commission paid by Lessor applicable to the
unexpired term of this Lease. The worth at the lime of award of the amount
referred to in provision (iii) of the prior sentence shall be computed by
discounting such amount at the discount rate of the Federal Reserve Bank of San
Francisco at the time of award plus one percent. Efforts by Lessor to mitigate
damages caused by Lessee's Default or Breach of this Lease shall not waive
Lessor's right to recover damages under this Paragraph. If termination of this
Lease is obtained through the provisional remedy of unlawful detainer, Lessor
shall have the right to recover in such proceeding the unpaid rent and damages
as are recoverable therein, or Lessor may reserve therein the right to recover
all or any part thereof in a separate suit for such rent and/or damages. If a
notice and grace period required under subparagraphs 13.1(b), (c) or (d) was not
previously given, a notice to pay rent or quit, or to perform or quit, as the
case may be, given to Lessee under any statute authorizing the forfeiture of
leases for unlawful detainer shall also constitute the applicable notice for
grace period purposes required by subparagraphs 13.11(b), (c) or (d). In such
case, the applicable grace period under subparagraphs 13.1(b), (c) or (d) and
under the unlawful detainer statute shall run concurrently after the one such
statutory notice, and the failure of Lessee to cure the Default within the
greater of the two such grace periods shall constitute both an unlawful detainer
and a Breach of this Lease entitling Lessor to the remedies provided for in this
lease and/or by said statute.

     (b) Continue the Lease and Lessee's right to possession in effect (in
California under California Civil Code Section 1951.1) after Lessee's Breach and
abandonment and recover the rent as it becomes due, provided Lessee has the
right to sublet or assign, subject only to reasonable limitations. See
Paragraphs 12 and 36 for the limitations in assignment and subletting which
limitations Lessee and Lessor agree are reasonable. Acts of maintenance or
preservation, efforts to relet the Premises, or the appointment of a receiver to
protect the Lessor's interest under the Lease, shall not constitute a
termination of the Lessee's right to possession.

     (c) Pursue any other remedy now or hereafter available to Lessor under the
laws or judicial decisions of the state wherein the Premises are located.

     (d) The expiration or termination of this Lease and/or the termination of
Lessee's right to possession shall not relieve Lessee from liability under any
indemnity provisions of this lease as to matters occurring or accruing during
the term hereof or by reason of Lessee's occupancy of the Premises.

     13.4 LATE CHARGES. Lessee hereby acknowledges that (ate payment by Lessee
to Lessor of rent and other sums due hereunder will cause Lessor to incur costs
not contemplated by this lease, the exact amount of which will be extremely
difficult to ascertain. Such costs include, but are not limited to, processing
and accounting charges, and late charges which may be imposed upon Lessor by the
terms of any ground lease, mortgage or trust deed covering the Premises.
Accordingly, if any installment of rent or any other sum due from Lessee shall
not be received by Lessor or Lessor's designee within live (5) days after such
amount shall be due. then, without any requirement for notice to Lessee. Lessee
shall pay to Lessor a late charge equal to six percent (6%) of such overdue
amount. The parties hereby agree that such late charge represents a fair and
reasonable estimate of the costs Lessor will incur by reason of late payment by
lessee. Acceptance of such late charge by Lessor shall in no event constitute a
waiver of Lessee's Default or Breach with respect to such overdue amount nor
prevent Lessor from exercising any of the other rights and remedies granted
hereunder. In the event that a late charge is payable hereunder, whether or not

as are pertinent only to and applicable only during the initial Term or any
prior extension Term of this Lease, and except that the Base Rent during the
extension period shall be equal to the Base Rent in effect immediately preceding
the extension period increased by the same percentage, if any, by which the
Consumer Price Index figure for the last calendar month preceding the extension
period shall have increased over the Consumer Price Index figure for the same
calendar month of the preceding calendar year. "Consumer Price Index" shall
refer to the Consumer Price Index:, All Urban Consumers, Los Angeles - Anaheim -
Riverside Metropolitan Area (All Items), compiled by the U.S. Department of
Labor, Bureau of Labor Statistics (1982-1984 = 100). If the 1982-1984 base of
the Consumer Price index should be changed, then the new base shall be converted
to the 1982-1984 base and the base as so converted shall be used. In the event
the Bureau shall cease to publish the Consumer Price Index:, then the successor
or most nearly comparable index, shall be used. In no event shall the Base Rent
be decreased at any time pursuant to the provisions of this paragraph
notwithstanding any decrease in the Consumer Price Index. In the event an
increase in Base Rent for an extension period is not, because of the publishing
date of the applicable Consumer Price Index, determinable as of the beginning of
the extension period, Lessee shall continue to pay the Base Rent then in effect
until the applicable increase is determined, at which time Lessee shall pay
Lessor an amount equal to such increase multiplied by the number of months since
the beginning of the extension period for which Lessee had not yet paid the
increased Base Rent.
