AGREEMENT: NOW, THEREFORE, the parties hereto, for themselves, their successors and assigns, mutually covenant and agree as follows: 1. Subject Premises. Software AG hereby sublets to Systems Management, and Systems Management hereby sublets from Software AG, the Subject Premises for the term and upon the conditions hereafter provided. The Subject Premises is depicted in the diagram attached hereto as Exhibit A. 2. Specifications. Software AG is subletting the Subject Premises in its "as is" condition existing on the date possession is delivered to Systems Management. Except as otherwise specifically set forth herein, Systems Management is subletting the Subject Premises from Software AG without requiring any alterations, improvements, repairs, or decorations to be made by Software AG, Master Tenant, or Master Landlord, or at Software AG's, Master Tenant's, or Master Landlord's expense, either at the time possession is given to Systems Management or during the entire term of this Agreement, or any extension thereof. In connection therewith, Systems Management represents that it has thoroughly examined the Subject Premises. Software AG acknowledges that to the best of its knowledge the Subject Premises are in a structurally sound condition, and the heating, ventilation, and air conditioning systems and all other mechanical, electrical and plumbing systems serving the Subject Premises are in good working order and condition. Software AG shall deliver the Subject Premises to Systems Management in broom-clean condition. Page 1 of 9 3. Term. The term of this Agreement shall commence upon the earlier of Systems Management's actual occupancy for its intended use or July 15, 2001 (the "Commencement Date"), provided that Master Landlord and Master Tenant give their consents to the terms of this Agreement. The Agreement term shall end on September 30, 2005, or on such earlier date upon which said term may expire or be terminated pursuant to any of the conditions or limitations or other provisions of this Agreement or pursuant to law. In the event Master Landlord's or Master Tenant's consent has not been obtained within forty-five (45) days after full execution of this Agreement by both Software AG and Systems Management, or such later date as Software AG and Systems Management may agree to in writing, this Agreement shall be and will become null and void and of no further force or effect. 4. Monthly Base Rent. The monthly base rent which Systems Management hereby agrees to pay to Software AG in advance, in equal monthly installments, and which Software AG hereby agrees to accept, shall be the sum of Sixteen Thousand Seven Hundred Thirty-Seven and 75/100 Dollars ($16,737.75), commencing at the beginning of the term of this Agreement and continuing thereafter on the first day of each and every calendar month during the term of this Agreement. If the obligation of Systems Management to pay rent hereunder begins on a day other than on the first day of a calendar month, rent from such date until the first day of the following calendar month shall be prorated at the rate of one-thirtieth (1/30th) of the monthly installment for each day payable in advance. The monthly base rent, additional rent, and any other charges herein reserved or payable shall be paid to Software AG at its offices as noted in this Agreement, to the attention of the Accounts Receivable Department; or at such other address as Software AG may designate in writing. Such amounts shall be paid in lawful money of the United States of America without demand therefor and without any deduction, setoff, or abatement whatever, except as expressly provided in this Agreement. 5. Base Rental Increase. Upon each anniversary of the Commencement Date, the Monthly Base Rent shall be increased by three percent (3%) of the previous year's Monthly Base Rent payable by Systems Management. 6. Additional Rent. Systems Management agrees to pay to Software AG, as additional rent under this Agreement, its pro rata share of the amount of any additional rent payable by Software AG under the Sublease pursuant to the applicable sections of the Sublease pertaining to real estate taxes and operating costs during the calendar year 2001. Software AG shall give Systems Management copies of all relevant statements and bills received by it pursuant to the applicable provisions of the Sublease, together with a statement of the amount of additional rent, if any, which Systems Management is required to pay under this Section. Systems Management shall pay additional rent within thirty (30) days of receipt of this statement. Systems Management shall also pay to Software AG, as additional rent, its pro rata share of all charges for any additional services provided to Systems Management by the Master Landlord, including, without limitation, charges and fees for alterations and after-hours heating and air-conditioning services. Systems Management's obligation to pay additional rent shall survive the termination of this Agreement for twelve (12) months, but only with respect to the period prior to the termination date. Notwithstanding anything to the contrary in this Agreement or the Sublease, Systems Management shall not be obligated to pay any fees or costs charged by the Master Tenant for any penalties, interest, or other costs related to Software AG's failure to make timely payment of any amount owed under the Sublease. 7. Security Deposit. Systems Management shall pay to Software AG, on the Effective Date, a security deposit in the amount of Thirty-three Thousand Four Hundred Seventy-five and 50/100 Dollars ($33,475.50) (the "Security Deposit").

Software AG shall pay to Systems Management interest on the total amount of the Security Deposit at an interest rate equal to three percent (3%) per annum; such interest shall accrue during the entire term of this Agreement.

Page 2 of 9 9. Alterations. 9.1 Excepting for cosmetic or decorative alterations and any provisions herein to the contrary, Systems Management shall not make any alteration, improvement, or installation (hereinafter called "Alterations") in or to the Subject Premises, without in each instance obtaining the prior written consent of the Master Tenant and Software AG, which consent of Software AG shall not be unreasonably withheld. If any Alterations are made without consent, the Master Tenant or Software AG may require Systems Management to remove the same, and may require Systems Management to correct, repair, and restore the Subject Premises and any damage arising from such removal, and Systems Management shall be liable for any and all direct and incremental costs and expenses incurred by the Master Tenant or Software AG in the performance of this work. 9.2 Systems Management may have Alterations performed by contractors of its own choice, at its expense, provided that Systems Management has obtained written approval of the contractor by the Master Landlord, Master Tenant and Software AG, which consent of Software AG shall not be unreasonably withheld.

If, within fifteen (15) business days after written notice, Systems Management fails or refuses to remove such Alterations, or fails to correct, repair, and restore the Subject Premises, Software AG may cause the same to be removed, and repairs and restoration to be made, in which event, Systems Management shall reimburse the party that caused said Alterations to be removed and repairs to be made for the cost of such removal, repairs, and restoration, together with any and all damages that such party, the Master Landlord, the Master Tenant, or Software AG may suffer and sustain by reason of Systems Management's failure or refusal to remove said Alterations. 10. Systems Management's Personal Property.

The receipt and retention by Software AG of monthly base rent or additional rent from anyone other than Systems Management shall not be deemed a waiver of the breach by Systems Management of any covenant, agreement, term or provision of this Agreement, or as the acceptance of such other person as a tenant, or as a release of Systems Management from the further keeping, observance or performance by Systems Management of the covenants, agreements, terms, provisions and conditions herein contained. The receipt and retention by Software AG of monthly base rent or additional rent with knowledge of the breach of any covenant, agreement, term, provision or condition herein contained shall not be deemed a waiver of such breach. 19.
