Company's average headcount to the total Titan Group average headcount as of the
last day of the last fiscal year and as of the end date of each of the four
quarters of the current fiscal year ("Human Resources Fee"). Prior to the

for such fiscal year and Company shall pay Titan the estimated annual Corporate
Services Fee in twelve equal monthly installments. At the end of each fiscal

Services Fee for the new fiscal year and invoice the Company for any

Titan's sole and exclusive liability for any breach of by Titan of Section 2,
and for any damages of the Company suffered or incurred directly or indirectly
in connection with the provision of Services by Titan (whether any claim related

basis or as required in the event that the Company is unable to arrange for
another source for such services or as otherwise required by Titan in acting in
its capacity as the majority stockholder of the Company, then Titan shall charge
the Company, and the Company shall pay Titan, on a monthly basis, a fee equal to
the market rate for comparable services. The obligations in this Section 5.3

3.       OTHER FACILITIES OBLIGATIONS.

         (a) This Agreement is subject and subordinate to all of the terms and
conditions of the Master Leases. Except for the direct payment of rent, landlord
pass-through expenses or other payment under the Master Lease below, the Company
shall perform the obligations of Titan as Tenant under the Master Lease to the
extent such obligations are applicable to the Subleased Premises pursuant to the
Agreement. Subject to Paragraph 4 of this Agreement, in the event of the
termination of the Titan's interest as Tenant under the Master Lease for any
reason, then this Agreement shall terminate coincidentally therewith without any
liability of Titan to the Company.

         (b) All applicable terms and conditions contained in the Master Lease
are incorporated in this Agreement by reference, and made a part hereof as if
set forth herein at length; with Titan being substituted for the "Landlord"
under the Master Lease, and Subleased Premises being substituted for "Premises"
under the Master Lease. Notwithstanding the foregoing, it is understood and
agreed that Titan shall not be obligated to perform any of the obligations of
Landlord under the Master Lease with respect to the provisions of the Master
Lease incorporated into this Agreement and the Company agrees to look solely to
Landlord for the performance of such obligations. Subject to Paragraph 3(d) of
this Agreement, Titan will not be liable to the Company for any failure by
Landlord to perform its obligations under the Master Lease, nor will such
failure by Landlord excuse performance by the Company of its obligations
hereunder.

         (c) The Company hereby agrees to indemnify and hold Titan harmless from
and against any and all claims, liabilities, losses, damages and expenses
(including reasonable attorneys' fees) incurred by Titan arising out of, from or
in connection with (i) the use or occupancy of the Subleased Premises by the
Company, (ii) any breach or default by the Company under this Agreement, or
(iii) the failure of the Company to perform any obligation under the terms and
provisions of the Master Lease assumed by the Company hereunder or required to
be performed by the Company as provided herein from and after the Commencement
Date of this Agreement.

                                       2.
