Lease Agreement

This Lease Agreement, dated October 22, 2003, by and between WINTHROP RESOURCES CORPORATION (the “Lessor”) with an office located at 11100 Wayzata Boulevard, Suite 800, Minnetonka, Minnesota 55305 and NCI INFORMATION SYSTEMS, INC. (the “Lessee”) with an office located at 11730 Plaza America Drive, Reston, VA 20190 .

Lessor hereby leases or grants to the Lessee the right to use and Lessee hereby rents and accepts the right to use the equipment listed by serial number and related services, and software and related services on the Lease Schedule(s) attached hereto or incorporated herein by reference from time to time (collectively, the equipment, software and services are the “Equipment”), subject to the terms and conditions hereof, as supplemented with respect to each item of Equipment by the terms and conditions set forth in the appropriate Lease Schedule. The term “Lease Agreement” shall include this Lease Agreement and the various Lease Schedule(s) identifying each item of Equipment or the appropriate Lease Schedule(s) identifying one or more particular items of Equipment.

This Lease Agreement is effective from the date it is executed by both parties. The term of this Lease Agreement, as to all Equipment designated on any particular Lease Schedule, shall commence on the Installation Date for all Equipment on such Lease Schedule and shall continue for an initial period ending that number of months from the Commencement Date as set forth in such Lease Schedule (the “Initial Term”) and shall continue from year to year thereafter until terminated. The term of this Lease Agreement as to all Equipment designated on any particular Lease Schedule may be terminated without cause at the end of the Initial Term or any year thereafter by either party mailing written notice of its termination to the other party not less than one-hundred twenty (120) days prior to such termination date.

The Installation Date for each item of Equipment shall be the day said item of Equipment is installed at the Location of Installation, ready for use, and accepted in writing by the Lessee. The Commencement Date for any Lease Schedule is the first of the month following installation of all the Equipment on the Lease Schedule, unless the latest Installation Date for any Equipment on the Lease Schedule falls on the first day of the month, in which case that is the Commencement Date. The Lessee agrees to complete, execute and deliver a Certificate of Acceptance to Lessor upon installation of the Equipment.

The lease charges for the Equipment leased pursuant to this Lease Agreement shall be the aggregate “Monthly Lease Charge(s)” as set forth on each and every Lease Schedule executed pursuant hereto (the aggregate “Monthly Lease Charge(s)” are the “Lease Charges”). Lessee agrees to pay to Lessor the Lease Charges in accordance with the Lease Schedule(s), and the payments shall be made at Lessor’s address indicated thereon.

1

The Lease Charges shall be paid by Lessee monthly in advance with the first full month’s payment due on the Commencement Date. The Lease Charge for the period from the Installation Date to the Commencement Date (the “Installation Period”) shall be an amount equal to the “Monthly Lease Charge” divided by thirty (30) and multiplied by the number of days from and including the Installation Date to the Commencement Date and such amount shall be due and payable upon receipt of an invoice from Lessor. Charges for taxes made in accordance with Section 4 and charges made under any other provision of this Lease Agreement and payable by Lessee shall be paid to Lessor at Lessor’s address specified on the Lease Schedule(s) on the date specified in invoices delivered to Lessee. If payment, as specified above, is not received by Lessor on the due date, Lessee agrees to and shall pay, to the extent permitted by law, on demand, as a late charge, an amount equal to one and one-half percent (1½ %), or the maximum percentage allowed by law if less, of the amount past due (“Late Charges”). Late Charges will accrue until billed by Lessor. Late Charges shall be charged and added to any past due amount(s) on the date such payment is due and every thirty (30) days thereafter until all past due amounts are paid in full to Lessor.

In addition to the Lease Charges set forth in Section 3, the Lessee shall reimburse Lessor for all license or registration fees, assessments, sales and use taxes, rental taxes, gross receipts taxes, personal property taxes and other taxes now or hereafter imposed by any government, agency, province or otherwise upon the Equipment, the Lease Charges or upon the ownership, leasing, renting, purchase, possession or use of the Equipment, whether the same be assessed to Lessor or Lessee (the “Taxes”). Lessor shall file all property tax returns and pay all Taxes when due. Lessee, upon notice to Lessor, may, in Lessee’s own name, contest or protest any Taxes, and Lessor shall honor any such notice except when in Lessor’s sole opinion such contest is futile or will cause a levy or lien to arise on the Equipment or cloud Lessor’s title thereto. Lessee shall, in addition, be responsible to Lessor for the payment and discharge of any penalties or interest as a result of Lessee’s actions or inactions. Nothing herein shall be construed to require Lessee to be responsible for any federal or state taxes or payments in lieu thereof, imposed upon or measured by the net income of Lessor, or state franchise taxes of Lessor, or except as provided hereinabove, any penalties or interest resulting from Lessor’s failure to timely remit such tax payments.

Lessee shall accept delivery of and install the Equipment before such time as the applicable vendor requires payment for such Equipment.

All transportation charges upon the Equipment for delivery to Lessee’s designated Location of Installation are to be paid by Lessee. All rigging, drayage charges, structural alterations, rental of heavy equipment and/or other expense necessary to place the Equipment at the Location of Installation are to be promptly paid by Lessee.

Lessee agrees to pay for the actual installation of the Equipment at Lessee’s site. Lessee shall make available and agrees to pay for all costs associated with providing a suitable place of installation and necessary electrical power, outlets and air conditioning required for operating the Equipment as defined in the Equipment manufacturer’s installation manual or instructions. All supplies consumed or required by the Equipment shall be furnished and paid for by Lessee.

2

On the day following the last day of the lease term associated with a Lease Schedule (the “Return Date”), Lessee shall cause and pay for the Equipment on that Lease Schedule to be deinstalled, packed using the manufacturer’s standard packing materials and shipped to a location designated in writing by Lessor (the “Return Location”). If the Equipment on the applicable Lease Schedule is not at the Return Location within ten (10) days of the Return Date, or Lessee fails to deinstall and ship the Equipment on the Return Date, then any written notice of termination delivered by Lessee shall become void, and the Lease Schedule shall continue in accordance with this Lease Agreement. Irrespective of any other provision hereof, Lessee will bear the risk of damage from fire, the elements or otherwise until delivery of the Equipment to the Return Location. At such time as the Equipment is delivered to the Lessor at the Return Location, the Equipment will be at the risk of Lessor.

Lessee, at its sole expense, shall maintain the Equipment in good working order and condition. Lessee shall enter into, pay for and maintain in force during the entire term of any Lease Schedule, a maintenance agreement with the manufacturer of the Equipment providing for continuous uninterrupted maintenance of the Equipment (the “Maintenance Agreement”). Lessee will cause the manufacturer to keep the Equipment in good working order in accordance with the provisions of the Maintenance Agreement and make all necessary adjustments and repairs to the Equipment. The manufacturer is hereby authorized to accept the directions of Lessee with respect thereto. Lessee agrees to allow the manufacturer full and free access to the Equipment. All maintenance and service charges, whether under the Maintenance Agreement or otherwise, and all expenses, if any, of the manufacturer’s customer engineers incurred in connection with maintenance and repair services, shall be promptly paid by Lessee. Lessee warrants that all of the Equipment shall be in good working order operating according to manufacturer’s specification and eligible for the manufacturer’s standard maintenance agreement upon delivery to and inspection and testing by the Lessor. If the Equipment is not free of physical defect or damage, operating according to manufacturer’s specification, in good working order and/or eligible for the manufacturer’s standard maintenance agreement, then Lessee agrees to reimburse Lessor for all costs, losses, expenses and fees associated with such equipment and the repair or replacement thereof.

The Equipment shall, at all times, be the sole and exclusive property of Lessor. Lessee shall have no right or property interest therein, except for the right to use the Equipment in the normal operation of its business at the Location of Installation, or as otherwise provided herein. The Equipment is and shall remain personal property even if installed in or attached to real property. Lessor shall be permitted to display notice of its ownership on the Equipment by means of a suitable stencil, label or plaque affixed thereto.

Lessee shall keep the Equipment at all times free and clear from all claims, levies, encumbrances and process. Lessee shall give Lessor immediate notice of any such attachment or other judicial process affecting any of the Equipment. Without Lessor’s written permission, Lessee shall not attempt to or actually: (i) pledge, lend, create a security interest in, sublet, exchange, trade, assign, swap, use for an allowance or credit or otherwise; (ii) allow another to use; (iii) part with possession; (iv) dispose of; or (v) remove from the Location of Installation, any item of Equipment. If any item of Equipment is exchanged, assigned, traded, swapped, used for an allowance or credit or otherwise to acquire new or different equipment (the “New Equipment”) without Lessor’s prior written

fconsent, then all of the New Equipment shall become Equipment owned by Lessor subject to this Lease Agreement and the applicable Lease Schedule.

Any feature(s) installed on the Equipment at the time of delivery which are not specified on the Lease Schedule(s) are and shall remain the sole property of the Lessor.

Lessee shall cause the Equipment to be operated in accordance with the applicable vendor’s or manufacturer’s manual of instructions by competent and qualified personnel.

Lessor is hereby authorized by Lessee to cause this Lease Agreement or other instruments, including Uniform Commercial Code Financing Statements, to be filed or recorded for the purposes of showing Lessor’s interest in the Equipment. Lessee agrees to execute any such instruments as Lessor may request from time to time.

Upon prior written notice to Lessor, Lessee may, at its own expense, make minor alterations in or add attachments to the Equipment, provided such alterations and attachments shall not interfere with the normal operation of the Equipment and do not otherwise involve the pledge, assignment, exchange, trade or substitution of the Equipment or any component or part thereof. All such alterations and attachments to the Equipment shall become part of the Equipment leased to Lessee and owned by Lessor. If, in Lessor’s sole determination, the alteration or attachment reduces the value of the Equipment or interferes with the normal and satisfactory operation or maintenance of any of the Equipment, or creates a safety hazard, Lessee shall, upon notice from Lessor to that effect, promptly remove the alteration or attachment at Lessee’s expense and restore the Equipment to the condition the Equipment was in just prior to the alteration or attachment.

Lessee shall assume and bear the risk of loss, theft and damage (including any governmental requisition, condemnation or confiscation) to the Equipment and all component parts thereof from any and every cause whatsoever, whether or not covered by insurance. No loss or damage to the Equipment or any component part thereof shall impair any obligation of Lessee under this Lease Agreement, which shall continue in full force and effect except as hereinafter expressly provided. Lessee shall repair or cause to be repaired all damage to the Equipment. In the event that all or part of the Equipment shall, as a result of any cause whatsoever, become lost, stolen, destroyed or otherwise rendered irreparably unusable or damaged (collectively, the “Loss”) then Lessee shall, within ten (10) days after the Loss, fully inform Lessor in writing of such a Loss and shall pay to Lessor the following amounts: (i) the Monthly Lease Charges (and other amounts) due and owing under this Lease Agreement at the time of the Loss, plus (ii) one-hundred twelve (112%) percent of the original cost of the Equipment subject to the Loss (or Event of Default, as defined hereinafter) amortized by the Monthly Lease Charges received by Lessor during the Initial Term using an amortization rate of 350 basis points over the interest rate of the three (3) year United States Treasury Note as reported by The Wall Street Journal on the Commencement Date (collectively, the sum of (i) plus (ii) shall be the “Casualty Loss Value”). Upon receipt by Lessor of the Casualty Loss Value: (i) the applicable Equipment shall be removed from the Lease Schedule; and (ii) Lessee’s obligation to pay Lease Charges associated with the applicable Equipment shall cease. Lessor may request, and Lessee shall complete, an affidavit(s) which swears out the facts supporting the Loss of any item of Equipment.

Until the Equipment is returned to Lessor or as otherwise herein provided, whether or not this Lease Agreement has terminated as to the Equipment, Les
