EXHIBIT C

LEASEHOLD IMPROVEMENTS TO BUILT-OUT SPACE

In
addition to the mutual covenants contained in the Lease Modification Agreement of which this Exhibit is a part, Lessor and Lessee further mutually agree as follows:





After
Lessee's Space Plans for any Leasehold Improvements have been approved in writing by Lessor, Lessor shall cause Lessee's Leasehold Improvements to be installed by Lessor's
contractor in accordance with the schedule in this Paragraph. Prior to commencing such Leasehold Improvements, Lessor shall submit to Lessee an itemized statement of the cost of such work if the cost
of such work exceeds $156,393.00, which cost shall include space planning expenses (Lessee shall cause its space planner to submit its cost for space plans no later than December 17, 1999) and
the contractor's fee. Lessor shall endeavor to provide Lessee with such itemized statement within ten (10) business days following Lessor's approval of Lessee's proposed Space Plans. If Lessee
approves such statement, Lessee shall sign the

5



statement
and return same to Lessor (along with the dollar amount of the total Excess Improvement Costs indicated in the statement) within three days after Lessee's receipt of such statement. Promptly
following Lessor's receipt of such payment and signed statement from Lessee, Lessor shall sign a copy of the statement and return same to Lessee, and Lessor shall direct its contractor to proceed with
such Leasehold Improvements and any Leasehold Improvements affected thereby. Any difference between Lessee's pre-payment for the Excess Improvement Costs (based on the aforementioned itemized
statement) and the actual final cost of same shall be reconciled between Lessor and Lessee, promptly following completion of such work and occupancy of the Premises by Lessee. If Lessee fails to sign
such itemized statement and return same to Lessor (along with the aforementioned pre-payment) within three days after Lessee's receipt of such statement from Lessor, such failure shall be deemed a
disapproval of such statement, Lessor shall no longer be bound by any of the cost figures for such Leasehold Improvements indicated in such statement, and Lessor's contractor shall not proceed with
such Leasehold Improvements or with any Leasehold Improvements affected thereby. In addition, Lessee shall be responsible for the resulting delay and increased cost, if any, in completing any
Leasehold Improvements affected thereby.

If
Lessee shall request any change(s), addition(s) or deletion(s), hereinafter collectively called "change(s)", to approved Space Plans for the Leasehold Improvements, Lessor shall
promptly (following written request by Lessee) give Lessee a written estimate of (i) the maximum cost of engineering and design services to prepare revised Space Plans in accordance with such
request and (ii) the time delay expected because of such request. Once Lessee has approved such estimate in writing (or has indicated in writing that it is willing to pay the full amount of such costs
for revised Space Plans and will accept any time delay caused by such change(s), without an estimate of the amount of such costs or delay), Lessor shall have revised Space Plans prepared (if needed),
and Lessee shall reimburse Lessor for the cost thereof, promptly following Lessee's receipt of an invoice or notice from Lessor indicating the actual final cost of the revised Space Plans. Lessor
shall endeavor to provide Lessee with an itemized statement indicating the cost (in addition to the cost of revising the Space Plans) which will be chargeable to Lessee by reason of such change(s). If
Lessee approves such statement, Lessee shall sign the statement and return same to Lessor (along with the dollar amount of the total cost of the change(s) indicated in the aforementioned statement and
the reimbursement for the cost of the revised Space Plans, if such reimbursement has not already been made) within three days after Lessee's receipt of such statement, if the cost of the changes plus
the original cost of the Leasehold Improvements exceeds $156,393.00. Promptly following Lessor's receipt of such payment and signed statement from Lessee, Lessor shall sign a copy of the statement and
return same to Lessee, and Lessor shall direct its
contractor to proceed with such change(s) and any Leasehold Improvements affected thereby. Any difference between Lessee's pre-payment (based on the aforementioned statement) for the change(s) and the
actual final cost of such change(s) shall be reconciled between Lessor and Lessee, promptly following completion of such change(s) and occupancy of the Premises by Lessee. If Lessee fails to sign such
statement and return same to Lessor, along with the aforementioned payment(s), within three (3) days after Lessee's receipt of such statement from Lessor, then (i) such failure shall be deemed
a disapproval of such statement, (ii) Lessor shall no longer be bound by any of the cost figures for such change(s) indicated in such statement, (iii) Lessor's contractor shall not
proceed with such change(s) or with any Leasehold Improvements affected thereby, and (iv) Lessee shall promptly reimburse Lessor for the cost of the revised Space Plans for such change(s), if
Lessee has not already done so. In addition, Lessee shall be responsible for the resulting delay and increased cost, if any, in completing any Leasehold Improvements affected thereby.

The
Commencement Date of the Lease term shall not be delayed by any of the following:

Accordingly,
Lessor may tender the Premises to Lessee on or after the Commencement Date (set forth in Paragraph 1 of the Lease Modification Agreement) not less than seven (7) days after Lessee
is served with a written notice stating that if it had not been for delay(s) which this Paragraph 5 states shall not postpone the Commencement Date of the Lease term, the Premises would be or
would have been ready for occupancy on the date specified in such notice, which date shall be prior to or within said seven (7) day period. In such event, Lessor's obligations under this Exhibit shall
be deemed completed, for the purpose of determining the Commencement Date and for any other purpose, as of the date on which the Premises are tendered to Lessee.

If
Lessee's requirements with respect to any of the Leasehold Improvements is less than the stated allowance, the cost savings which accrue therefrom may be applied to offset in whole
or in part Lessee's cost of any other Leasehold Improvement(s) described in Paragraph 2 hereof which exceeds the stated allowance. However, in no event shall Lessee be entitled to a cash
payment or credit against rent on account of allowances for Leasehold Improvements described in Paragraph 2 hereof which exceed Lessee's requirements.

Notwithstanding
any allowances set forth in Paragraph 2 hereof, Lessor's total contribution for Leasehold Improvements shall not exceed $156,393.00. All costs in excess of such
amount are to be paid by Lessee, pursuant to the provisions of this Exhibit "C".
