Subtenant further acknowledges that except as set forth in the Work Letter or expressly set forth in this Sublease, no representations as to the condition or repair of the Sublease Premises and no promises to alter, remodel or improve the Sublease Premises have been made by Landlord, Sublandlord or any agents of either party.

Subrental. --------- (a) Base Rental. Beginning with the Sublease Commencement Date and ----------- thereafter during the Sublease Term and ending on the Sublease Expiration Date, Subtenant shall pay to Sublandlord monthly installments of base rent ("Base Rental") as set forth below. The first monthly installment of Base Rental and Operating Expenses shall be paid by Subtenant upon the execution of this Sublease. Base Rental and additional rent shall hereinafter be collectively referred to as "Rent." 2 Monthly Base Rental Period (Per Square Foot) ------ ----------------- November 1, 2000 - July 31, 2001 $1.55 August 1, 2001 - July 31, 2002 $1.61 August 1, 2002 - July 31, 2003 $1.68 August 1, 2003 - April 30, 2004 $1.74 May 1, 2004 - April 30, 2005 $1.82 May 1, 2005 - April 30, 2006 $1.90 May 1, 2006 - April 30, 2007 $1.99 May 1, 2007 - April 30, 2008 $2.08 May 1, 2008 - April 30, 2009 $2.17 May 1, 2009 - April 30, 2010 $2.27 (b) Operating Expenses. Beginning with the Sublease Commencement ------------------ Date and thereafter during the Sublease Term, Subtenant shall pay to Sublandlord as additional rent under this Sublease, Subtenant's Proportionate Share of the amounts that Sublandlord, as Tenant, has to pay Landlord, pursuant to Paragraph 7 of the Phase B Lease. "Subtenant's Proportionate Share" shall mean the following: 100% of the Building in which the Phase B-2 Premises are located and 60% of Phase B of the Project. (c) Payment of Rent. Except as otherwise specifically provided in --------------- this Sublease, Rent shall be payable in lawful money without notice or demand, and without offset, counterclaim, or setoff in monthly installments, in advance, on the first day of each and every month during the Sublease Term. All of said Rent is to be paid to Sublandlord at its office at the address set forth in Paragraph 12 herein, or at such other place or to such agent and at such place as Sublandlord may designate by notice to Subtenant. Any additional rent payable on account of items which are not payable monthly by Sublandlord to Landlord under the Phase B Lease is to be paid directly to Sublandlord as and when such items are payable by Sublandlord to Landlord under the Phase B Lease unless a different time for payment is elsewhere stated herein. Sublandlord shall request that copies of all notices sent by Landlord pursuant to the Phase B Lease also be sent to Subtenant at the address set forth in Paragraph 12 below. In addition, Sublandlord agrees to provide Subtenant with copies of any notices, statements or invoices received by Sublandlord from Landlord pursuant to the terms of the Phase B Lease. (d) Security Deposit. Concurrently with the execution of this ---------------- Sublease, Subtenant shall deposit with Sublandlord the sum of One Hundred Thirty-Nine Thousand Five Hundred and no/100 Dollars ($139,500.00) ("Deposit"), which shall be held by Sublandlord as 3 security for the full and faithful performance by Subtenant of its covenants and obligations under this Sublease. The Deposit is not an advance Rent deposit, an advance payment of any other kind, or a measure of Sublandlord's damage in case of Subtenant's default. If Subtenant defaults in the full and timely performance of any or all of Subtenant's covenants and obligations set forth in this Sublease, then Sublandlord may, from time to time, without waiving any other remedy available to Sublandlord, use the Deposit, or any portion of it, to the extent necessary to cure or remedy the default or to compensate Sublandlord for all or a part of the damages sustained by Sublandlord resulting from Subtenant's default. Subtenant shall immediately pay to Sublandlord within five (5) days following demand, the amount so applied in order to restore the Deposit to its original amount, and Subtenant's failure to immediately do so shall constitute a default under this Sublease. If Subtenant is not in default with respect to the covenants and obligations set forth in this Sublease at the expiration or earlier termination of this Sublease, Sublandlord shall return the Deposit to Subtenant after the expiration or earlier termination of this Sublease. Sublandlord's obligations with respect to the Deposit are those of a debtor and not a trustee. Sublandlord shall not be required to maintain the Deposit separate and apart from Sublandlord's general and other funds and Sublandlord may commingle the Deposit with any of Sublandlord's general or other funds. Subtenant shall not at any time be entitled to interest on the Deposit. (e) Late Charge. In addition to any other remedies of Sublandlord ----------- hereunder, Subtenant shall, without notice or demand, add to the amount of any payment required to be made by Subtenant hereunder, and which is not paid and received by Sublandlord on or before the fifth (5th) business day of each calendar month, an amount equal to five percent (5%) of the delinquency for each month or portion thereof that the delinquency remains outstanding to compensate Sublandlord for the loss of the use of the amount not paid and the administrative costs caused by the delinquency; the parties agreeing that Sublandlord's damage by virtue of such delinquencies would be extremely difficult and impracticable to compute and the amount stated herein represents a reasonable estimate thereof. Any waiver by Sublandlord of any late charges or failure to claim the same shall not constitute a waiver of other late charges or any other remedies available to Sublandlord, such charge to accrue from the date upon which such amount was due until paid. 4. Signage. Subtenant shall have the right to install at ------- Subtenant's sole cost and expense up to two (2) business identification signs identifying Subtenant on the upper exterior of the building and adjacent to the building entrance doors of the building in which the Sublease Premises are located, subject to Landlord's prior written approval, which approval shall not be unreasonably withheld, delayed or conditioned. In addition, Subtenant shall have the right to install one (1) business identification sign on the Project's monument sign, subject to Landlord's prior written approval, which shall not be unreasonably withheld, delayed or conditions. Except for the foregoing, Subtenant shall have no right to install or keep Subtenant identification signs in any other location outside the Sublease Premises. The size, design, color and other physical aspects of all such permitted signs shall also be subject to Landlord's prior written approval, which approval shall not be unreasonably withheld, delayed or conditioned and shall also be subject to any covenants, conditions or restrictions encumbering the Sublease Premises and any applicable municipal or other governmental permits and approvals. The cost of all such signs, including the installation, maintenance and removal thereof, shall be at 4 Subtenant's sole cost and expense. If Subtenant fails to maintain its signs, or if Subtenant fails to remove same upon the expiration or earlier termination of this Sublease and repair any damage caused by such removal, Sublandlord may do so at Subtenant's expense and Subtenant shall reimburse Sublandlord for all actual costs incurred by Sublandlord to affect such removal. 5. Parking Density. 4.5 parking spaces per 1,000 square feet of the --------------- rentable area of the Sublease Premises. 6. Bonus Rent. Any Rent or other consideration realized by ---------- Subtenant under any sublease or assignment, in excess of the Rent payable hereunder, after amortization of all transaction costs reasonably incurred in connection therewith, including but not limited to reasonable brokerage commission incurred by Subtenant, legal fees, costs of improvements, shall be divided and paid, twenty-five percent (25%) to Subtenant, and seventy-five percent (75%) to Sublandlord ("Bonus Rent"). In any subletting or assignment undertaken by Subtenant, Subtenant shall diligently seek to obtain the maximum rental amount available in the marketplace for comparable space available for primary leasing. 7.

Subtenant agrees to indemnify Sublandlord, and hold it harmless, from and against any and all claims, damages, losses, expenses and liabilities (including reasonable attorneys' fees) incurred as a result of the non-performance, non-observance or non-payment of any of Sublandlord's obligations under the Phase B Lease applicable to the Sublease Premises which, as a result of this Sublease, became an obligation of Subtenant. Subtenant shall not do, nor permit to be done, any act or thing which is, or with notice or the passage of time would be, a default under this Sublease or the Phase B Lease (to the extent applicable to the Sublease Premises). Sublandlord agrees to indemnify Subtenant, and hold it harmless, from and against any and all claims, damages, losses, expenses and liabilities (including reasonable attorneys' fees) incurred as a result of the non-performance, non- observance or non-payment of any of Sublandlord's obligations under the Phase B Lease 9. Sublandlord's Obligations. Sublandlord agrees that Subtenant ------------------------- shall be entitled to receive all services and repairs to be provided by Landlord to Sublandlord under the Phase B Lease. Subtenant shall look solely to Landlord for all such services and shall not, under any circumstances, seek nor require Sublandlord to perform any of such services, nor shall Subtenant make any claim upon Sublandlord for any damages which may arise by reason of Landlord's default under the Phase B Lease. Any condition resulting from a default by Landlord shall not constitute as between Sublandlord and Subtenant an eviction, actual or constructive, of Subtenant and no such default shall excuse Subtenant from the performance or observance of any of its obligations to be performed or observed under this Sublease, or, except as otherwise provided in this Sublease, entitle Subtenant to receive any reduction in or abatement of the Rent provided for in this Sublease. In furtherance of the foregoing, and subject to Paragraph 11 hereof, Subtenant does hereby waive any cause of action and any right to bring any action 6 against Sublandlord by reason of any act or omission of Landlord under the Phase B Lease. Sublandlord covenants and agrees with Subtenant that Sublandlord will pay all fixed rent and additional rent payable by Sublandlord pursuant to the Phase B Lease to the extent that failure to perform the same would adversely affect Subtenant's use or occupancy of the Sublease Premises. In the event of a breach by Landlord of any term of the Phase B Lease, then Sublandlord's sole obligation in regard to its obligation under this Sublease shall be to diligently pursue the correction or cure by Landlord of Landlord's breach. Such efforts shall include, without limitation, upon Subtenant's request, (a) immediately notifying Landlord of its non-performance under the Phase B Lease and demanding that Landlord perform its obligations under the Phase B Lease and/or (b) assigning Sublandlord's rights under the Phase B Lease to Subtenant to the extent necessary to permit Subtenant to institute legal proceedings against Landlord to obtain the performance of Landlord's obligations under the Phase B Lease; provided, however, that if Subtenant commences a lawsuit or other action, Subtenant shall pay all costs and expenses incurred in connection therewith, and Subtenant shall indemnify Sublandlord against, and hold Sublandlord harmless from, all costs and expenses incurred by Sublandlord in connection therewith. 10. Default by Subtenant. In the event Subtenant shall be in default of -------------------- any covenant of, or shall fail to honor any obligation under, this Sublease, Sublandlord shall have available to it against Subtenant all of the remedies available (a) to Landlord under the Phase B Lease in the event of a similar default on the part of Sublandlord thereunder or (b) at law. 11. Quiet Enjoyment. So long as Subtenant pays all of the Rent due --------------- hereunder and performs all of Subtenant's other obligations hereunder, Sublandlord shall do nothing to affect Subtenant's right to peaceably and quietly have, hold and enjoy the Sublease Premises, and all of the rights, entitlements, and options granted to Subtenant hereunder. In the event, however, that Sublandlord defaults in the performance or observance of any of Sublandlord's obligations under this Sublease or Subtenant receives a notice of default on the part of Sublandlord from Landlord under the Phase B Lease, then Subtenant shall give written notice to Sublandlord specifying in what manner Sublandlord has defaulted. If such default shall not be cured within a reasonable time, but in no event later than thirty (30) days after Sublandlord's receipt of such written notice from Subtenant (except that if such default cannot be cured within said thirty (30) day period, this period shall be extended for an additional reasonable time, provided that Sublandlord commences to cure such default within such thirty (30) day period and proceeds diligently thereafter to effect such cure as quickly as possible), then Subtenant shall be entitled, at Subtenant's option, to cure such default and promptly collect from Sublandlord Subtenant's reasonable expenses in so doing (including, without limitation, reasonable attorneys' fees and court costs) unless such default by Sublandlord is caused by a default of Subtenant hereunder (in which case Sublandlord shall not be liable for Subtenant's costs to cure the default). Subtenant shall not be required to wait the entire cure period provided for herein if earlier action is required to prevent a termination by Landlord of the Phase B Lease and Sublandlord has failed to take such earlier action. Sublandlord shall not amend or modify the Phase B Lease in such a manner as to materially adversely affect Subtenant's use of the Sublease Premises or increase the obligations or decrease the rights of Subtenant hereunder, without the prior written consent of Subtenant, which may be granted or withheld at Subtenant's sole discretion. Anything contained in any provision of this Sublease to the contrary notwithstanding, Subtenant agrees, with respect 7 to the Sublease Premises, to comply with and remedy any default in this Sublease or the Phase B Lease which is Subtenant's obligation to cure, within the period allowed to Sublandlord under the Phase B Lease, even if such time period is shorter than the period otherwise allowed therein due to the fact that notice of default from Sublandlord to Subtenant is given after the corresponding notice of default from Landlord to Sublandlord. Sublandlord agrees to forward to Subtenant, promptly upon receipt thereof by Sublandlord, a copy of each notice of default received by Sublandlord in its capacity as Tenant under the Phase B Lease. Subtenant agrees to forward to Sublandlord, promptly upon receipt thereof, copies of any notices received by Subtenant from Landlord or from any governmental authorities. 12. Notices.

Termination of the Phase B Lease. If for any reason the term of the -------------------------------- Phase B Lease shall terminate prior to the Sublease Expiration Date, this Sublease shall automatically be terminated and Sublandlord shall not be liable to Subtenant by reason thereof unless said termination shall have been caused by the default of Sublandlord under the Phase B Lease, and said Sublandlord default was not as a result of a Subtenant default hereunder. To the extent that the Phase B Lease grants Sublandlord any discretionary right to terminate the Phase B Lease, whether due to casualty, condemnation, or otherwise, Sublandlord shall not exercise such right without the prior written consent of the Subtenant which may be withheld by Subtenant in its sole and absolute discretion. If Landlord seeks to terminate the Phase B Lease because of a default or alleged default by Sublandlord under the Phase B Lease (other than a default or alleged default caused by the default by Subtenant under this Sublease), Sublandlord shall take all action required to reinstate the Phase B Lease. Further, if Rent is abated under the Phase B Lease, Rent hereunder shall also be abated in the same proportion. 16. Limitation of Estate.
