                             CONSTRUCTION AGREEMENT

                                (Build to Suit)


                 Lessee and Lessor are executing, simultaneously with this
Build to Suit Construction Agreement ("Construction Agreement"), a Lease of
even date herewith (the "Lease").  This Construction Agreement is hereby
incorporated into the Lease as Exhibit "C."  Capitalized terms used and not
otherwise defined herein have the meanings set forth for them in the Lease.  In
consideration of the mutual covenants contained in the Lease, Lessee and Lessor
agree that the Premises shall be improved as set forth hereinafter.

         1.      BASE BUILDING.  The Base Building work shall be performed by
Lessor at Lessor's sole cost and expense prior to the Commencement Date.  The
term "Base Building" means the following elements of the Premises:  tilt-up
concrete building with concrete floors (without floor covering), roof and
unfinished perimeter walls; base sprinkler system (no extensions); utilities
stubbed to the building wall; landscaping; and parking.  All elements of the
initial construction of the Premises not included in the Base Building shall be
considered part of the Initial Improvements (as defined below).

         2.      PLANS AND SPECIFICATIONS.

                 (a)      Lessor and Lessee have approved the space plan (the
"Space Plan") for the Premises described in Schedule 1 attached hereto.

                 (b)      Based on the approved Space Plan, RGA Architects
("Lessor's Architect"), or another architect selected by Lessor and reasonably
acceptable to Lessee, shall prepare detailed plans, specifications and working
drawings ("Construction Documents") for the construction of leasehold
improvements in the Premises (the "Initial Improvements").  Lessee shall
approve the Construction Documents in writing within five (5) working days of
receipt thereof.  Lessee shall only have the right to disapprove the
Construction Documents due to errors and material deviations from the Space
Plan.

                 (c)      Lessee may disapprove the Construction Documents one
time without having delayed Lessor's space planner as described in Section
3(a), below.  Any subsequent disapprovals shall be considered a Tenant Delay
unless the disapproval is caused by errors made by Lessor's space planner or by
material deviations from the Space Plan that were noted in Lessee's initial
disapproval of the Construction Documents and that have not yet been corrected.




                                  Exhibit "C"
                                  Page 1 of 7

<PAGE>   2
         3.      INITIAL IMPROVEMENT COST.

                 (a)      Lessor shall enter into a contract with Oltman's
Construction Company ("Contractor"), or another contractor selected by Lessor
and reasonably acceptable to Lessee, to construct the Initial Improvements.
Based upon such contract, Lessor shall determine the cost of the Initial
Improvements (the "Initial Improvement Cost"), which may include the following:
cost of basic services for space plans, pricing plans, construction documents;
engineering fees; governmental agency plan check, permit and other fees; sales
and use taxes; Title 24 fees; testing and inspection costs and all other costs
to be expended by Lessor in the construction of the Initial Improvements, and a
Lessor construction management fee equal to five percent (5%) of the Initial
Improvement Cost (for purposes of which calculation such management fee shall
not be deemed included in the Initial Improvement Cost).  Within five (5)
working days of receipt by Lessee of the Initial Improvement Cost, Lessee shall
either approve the same in writing or shall provide Lessor with a detailed list
of revisions to the approved Construction Documents.  If Lessee would be
obligated under Section 3(b) to pay any excess cost, Lessee may revise the
Initial Improvement Cost one time without having caused a Tenant Delay as
described in Section 7 below in order to reduce such excess cost.  Any
subsequent revisions shall be considered a Tenant Delay unless the revision is
caused by Lessor's error.

                 (b)      Lessee shall be entitled to a construction allowance
in the amount of $350,000 ("Initial Improvement Allowance") for application
against the Initial Improvement Cost.  If the Initial Improvement Cost is in
excess of $350,000.00, Lessee shall pay such excess as provided herein.  No
more often than once per calendar month, Lessor shall provide Lessee with an
estimate of the Initial Improvement Costs payable during the following 30 days.
Lessor's estimate shall be based upon the Contractor's application for payment
for the Initial Improvements and upon Lessor's reasonable estimate of any other
elements of the Initial Improvement Costs payable during that period and shall
contain the architect's approval of that estimate.  With respect to the first
$700,000 of the Initial Improvement Costs, Lessee shall pay Lessor 50% of the
amount specified in Lessor's estimate.  The remaining 50% of that initial
$700,000 shall be advanced by Lessor out of the Initial Improvement Allowance.
At such time as Lessor has advanced the entire Initial Improvement Allowance,
Lessee shall be obligated to pay 100% of any Initial Improvement Costs
thereafter estimated by Lessor and incurred in connection with the construction
of the Initial Improvements monthly using the same procedure of Lessor's
estimates as provided for above in this Section 3(b).  All payments of Lessee's
share of the Initial Improvement Cost shall be paid to Lessor by Lessee within
five (5) business days after Lessor's delivery to Lessee of Lessor's estimate
of the amount





                                  Exhibit "C"
                                  Page 2 of 7

due.  If at any time Lessee does not timely pay to Lessor its share of the
Initial Improvement Costs when due under this Paragraph 3(b) (each, a "Late
Cost Payment"), time being of the essence of all such payments, Lessor shall
have the absolute right to stop all work and not resume that work unless and
until Lessee has paid Lessor (i) all tardy Initial Improvement Costs payments,
(ii) all damages caused by or resulting from Lessor's work stoppage under this
Paragraph 3(b), and (iii) if there occurs more than one Late Cost Payment, the
balance of the Initial Improvement Costs estimated to be payable by Lessee.
This remedy shall be in addition to Lessor's other remedies under the Lease for
such default by Lessee, including without limitation the right to terminate the
Lease.

                 (c)      If the Initial Improvement Cost increases, subsequent
to Lessee's approval, due to the requirements of any governmental agency,
Lessee shall pay Lessor the amount of such increase (except to the extent that
the estimated total Initial Improvement Cost then remains less than the amount
of the Initial Improvement Allowance) at the time and in the manner provided
for in Paragraph 3(b) of this Construction Agreement.

                 (d)      If Lessee requests a change in the Construction
Documents subsequent to approval of the Initial Improvement Cost, Lessor shall
notify Lessee promptly as to any increase in the Initial Improvement Cost and
as to any delay such change would cause in the construction of the Initial
Improvements.  Lessee shall approve or disapprove such change within five (5)
business days of Lessor's written notice; Lessor's failure to receive Lessee's
notice approving the same shall be deemed Lessee's disapproval of that change.
If Lessee approves such change, Lessee shall pay the amount of the increase
(except to the extent that the estimated total Initial Improvement Cost then
remains less than the amount of the Initial Improvement Allowance) at the time
and in the manner provided for in Paragraph 3(b) of this Construction
Agreement.

                 (e)      In the event that Lessee makes any such payments for
excess costs and, following the completion of the Initial Improvements and the
payment of the entire Initial Improvement Cost (as increased by any increases
under Paragraphs 3(c) or 3(b)), unexpended Initial Improvement Allowance funds
remain, Lessee shall be entitled to a credit against the initial Base Rent
otherwise payable by Lessee in the amount of the lesser of (i) the total of all
such payments made by Lessee or (ii) the amount of the unexpended Initial
Improvement Allowance funds.

         4.      CONSTRUCTION OF INITIAL IMPROVEMENTS.

                 (a)      Upon approval and payment (to the extent required
under this Agreement) by Lessee of the Initial Improvement Cost, Lessor shall
cause the Contractor





                                  Exhibit "C"
                                  Page 3 of 7
<PAGE>   4
to proceed to secure a building permit and commence construction of the Initial
Improvements.

                 (b)      Lessor shall endeavor to substantially complete
construction of the Initial Improvements as soon as is reasonably practicable.

         5.      COMMENCEMENT DATES.  Notwithstanding anything to the contrary
set forth in Paragraph 3 of the Lease, and subject to Section 6 below:

                 5.1    The date on which Lessee shall be entitled to occupy
the Office Area, and shall commence payment of rent therefor (whether or not
Lessee occupies the Office Area), under Paragraph 3.4 of the Lease (the "Office
Area Early Commencement Date") shall be the date that is the later of  March 1,
1997 or (ii) the date of Substantial Completion of the portion of the Initial
Improvements (the "Office Improvements") consisting of improvements to (or
improvements necessary for the occupancy of) the Office Area.  Notwithstanding
the foregoing, in the event that Lessee occupies the Office Area for its normal
business operations prior to the Office Area Early Commencement Date, Lessee
shall commence payment of rent and other payments for the Office Area on the
first date of such early occupancy.

                 5.2    The date on which the term of the Lease shall commence
under Paragraph 3.1 of the Lease (the "Commencement Date"), including for
purposes of Base Rent obligations (subject to Lessee's earlier obligation to
pay rent with respect to the Office Area as set forth above), shall be the date
that is the later of  June 1, 1997 or (ii) the date of Substantial Completion
of the remainder of the Initial Improvements.  In the event that the
Commencement Date occurs after June 1, 1997, the scheduled expiration date of
the Lease shall be extended for an equal number of days.  Notwithstanding the
foregoing, in the event that Lessee occupies any portion of the Premises
outside the Office Area for its normal business operations prior to the
Commencement Date, Lessee shall commence payment of rent for all portions of
the Premises outside the Office Area on the first date of such early occupancy.

For purposes of the Lease (including this Construction Agreement), "Substantial
Completion" of the Initial Improvements (or Office Improvements, as applicable)
shall occur upon (a) the completion of construction of the Initial Improvements
(or Office Improvements, as applicable) pursuant to the Construction Documents,
with the exception of any punch list items and any furniture, fixtures or
equipment to be installed by Lessee, and (b) the issuance of a temporary or
final Certificate of Occupancy for the entire Premises.





                                  Exhibit "C"
                                  Page 4 of 7
<PAGE>   5
         6.      DELAY IN SUBSTANTIAL COMPLETION.  If there shall be a delay or
there are delays in the Substantial Completion of the Office Improvements
and/or Initial Improvements as a result of Tenant Delays (as defined below),
then, notwithstanding anything to the contrary set forth in the Lease or this
Construction Agreement and regardless of the actual date of the Substantial
Completion of the Office Improvements and/or Initial Improvements, each of the
Office Area Early Commencement Date and the Commencement Date shall be deemed
to be the date the Office Area Early Commencement Date or Commencement Date, as
applicable, would have occurred but for the Tenant Delay or Delays.

         7.      TENANT DELAYS.  The following shall, to the extent that they
actually delay the Substantial Completion of the Office Improvements and/or
Initial Improvements, constitute "Tenant Delays" under the Lease and this
Agreement:

                 (a)      Lessee's failure to approve the Construction
Documents on or before the specified approval date, or Lessee's delay of
Lessor's space planner or architect in completion of the Construction
Documents; or

                 (b)      Lessee's delay in approval of the Initial Improvement
Cost, or failure to pay the excess Initial Improvement Cost within the time
limit provided; or

                 (c)      Lessee's modification of the Construction Documents
subsequent to its approval; or

                 (d)      Changes to the Base Building required by the
Construction Documents; or

                 (e)      A breach by Lessee of this Construction Agreement or
any other provision of the Lease; or

                 (f)      Any other unreasonable acts or omissions of Lessee,
or its agents, employees or contractors.

Lessor shall provide Lessee with written notice of any Tenant Delay within ten
(10) days of the occurrence thereof, and Lessor's failure to provide Lessee
with such written notice shall constitute Lessor's waiver of such Tenant Delay.
Only one such notice shall be required for each event constituting a Tenant
Delay.

         8.      NOTICE OF SUBSTANTIAL COMPLETION.  Lessor shall give Lessee at
least ten (10) business days' written notice of the date upon which Substantial
Completion of





                                  Exhibit "C"
                                  Page 5 of 7
<PAGE>   6
each of the Office Improvements and the Initial Improvements is estimated to
occur.

         9.      LESSEE'S LEASE DEFAULT.  Notwithstanding any provision to the
contrary contained in the Lease, if a material default as defined in the Lease,
or a default by Lessee under this Construction Agreement, has occurred at any
time on or before the Substantial Completion of the Initial Improvements, then
(a) in addition to all other rights and remedies granted to Lessor pursuant to
the Lease (including, without limitation, the right to terminate the Lease),
Lessor shall have the right to cause the Contractor to cease the construction
of the Initial Improvements (in which case Lessee shall be responsible for any
delay in the Substantial Completion of the Office Improvements and/or Initial
Improvements caused by such work stoppage as set forth in Section 7 of this
Construction Agreement and for all damages caused thereby), and (b) all other
obligations of Lessor under the terms of this Construction Agreement shall be
forgiven until such time as such default is cured pursuant to the terms of the
Lease.

         10.     PUNCHLISTS.  Within ten (10) business days after the later of
(a) Substantial Completion of the Office Improvements or (b) Lessee's occupancy
of the Office Area, Lessor, Lessee and the Contractor shall prepare a list (the
"First Punchlist") of remaining items to be completed by the Contractor with
respect to the Office Area.  Lessor shall cause the items on the First
Punchlist to be completed within thirty (30) days after delivery of the First
Punchlist to Lessee.  Within ten (10) business days after the later of (a)
Substantial Completion of the Initial Improvements or (b) Lessee's occupancy of
any portion of the Premises other than the Office Area, Lessor, Lessee and the
Contractor shall prepare a list (the "Second Punchlist") of remaining items to
be completed by the Contractor with respect to the portions of the Premises
outside the Office Area.  Lessor shall cause the items on the Second Punchlist
to be completed within thirty (30) days after delivery of the Second Punchlist
to Lessee.  Lessee shall permit reasonable access to the Premises by the
Contractor and Lessor so as to permit completion of the foregoing punchlist
items within the foregoing periods.

         11.     DETERMINATION OF RENTABLE AREA.  Upon the Substantial
Completion of the Initial Improvements, Lessor's Architect shall measure the
rentable square footage of the Premises (including without limitation the
mezzanine portion of the Office Area).  Such square footage shall be determined
by measuring to the outside finished surface of the permanent exterior building
walls (and, with respect to the mezzanine, to the outside finished surface of
the interior wall which demises the Office Area from the remainder of the
Premises), without deduction for columns or projections necessary to the
building.  Upon such determination of rentable area, all provisions of the
Lease which are dependent upon square footage (including without limitation the
calculation of Base Rent) shall be adjusted accordingly.
