	2.11.1.	Schedule 2.11 contains a true, correct and complete list of all pension, profit sharing, retirement, deferred compensation, welfare, insurance, disability, bonus, vacation pay, severance pay and other similar plans, programs or agreements, and every material personnel policy, whether reduced to writing or not, relating to any FSB Employees and maintained at any time by Federal or by any other member of a controlled group of corporations, group of trades or businesses under common control or affiliated service group which includes Federal (as defined for purposes of Section 414(b), (c) and (m) of the Code) (collectively, the "Federal Plans"). Federal has made available to CACI Sub true, correct and complete copies of all Federal Plans that have been reduced to writing, together with all documents establishing or constituting any related trust, annuity contract, insurance contract or other funding instrument, and summaries of those that have not been reduced to writing. With respect to all Federal Plans, Federal has made available to CACI Sub the latest Forms 5500. [Neither Federal nor any Affiliate has ever been obligated to contribute to any "multi-employer plan," as defined in Section 3(37) of ERISA.] Neither Federal nor any Affiliate has incurred any "withdrawal liability" calculated under Section 4211 of ERISA and, to Seller's Knowledge, there has been no event or circumstance which would cause Federal to incur any such liability. No plan previously maintained by Federal or its Affiliates which was subject to ERISA has been terminated; no proceedings to terminate any such plan have been instituted within the meaning of Subtitle C of Title IV of ERISA; and no reportable event within the meaning of Section 4043 of said Subtitle C has occurred with respect to any Federal Plan with respect to the FSB Employees, and no liability to the Pension Benefit Guaranty Corporation has been incurred with respect to the FSB Employees.

To Seller's Knowledge neither Federal nor any Affiliate, nor any of their directors, officers, employees or agents, nor any trustee or administrator of any trust created under the Federal Plans, has engaged in or been a party to any "prohibited transaction" as defined in Section 4975 of the Code and Section 406 of ERISA with respect to a Federal Plan which could subject CACI Sub or its Affiliates, directors or employees or the CACI plans or the trusts relating thereto or any party dealing with any of the CACI plans or trusts to any material tax or penalty on "prohibited transactions" imposed by Section 4975 of the Code. Neither the Federal Plans nor the trusts created thereunder have incurred any "accumulated funding deficiency," as such term is defined in Section 412 of the Code and regulations issued thereunder, whether or not waived.
	2.11.2.	Each Federal Plan intended to qualify under Section 401(a) of the Code has been determined by the Internal Revenue Service to so qualify, and the trusts created thereunder have been determined to be exempt from tax under Section 501(a) of the Code; copies of all determination letters have been delivered to CACI Sub; and, to Seller's Knowledge, nothing has occurred since the date of such determination letters which might cause the loss of such qualification or exemption. With respect to each Federal Plan which is a qualified profit sharing or stock bonus plan, all employer contributions accrued for the benefit of any FSB Employee for plan years ending prior to the Closing Date under the Federal Plan terms and applicable law have been made or accrued.
	2.11.3.	There are no actions, suits or claims pending or, to the Seller's Knowledge, threatened, with respect to any of the Federal Plans, and there are no outstanding written requests, other than routine requests for information concerning such Federal Plans, by participants, beneficiaries or any government agency. All of the liabilities of the FSB with respect to all of the Federal Plans are accurately reflected in the 2000 Balance Sheet.

There are no past or present actions, activities, circumstances, conditions, events or incidents, including, without limitation, the release, threatened release, emission, discharge or disposal of any Material of Environmental Concern by Federal or by any other person to Seller's Knowledge, that could form the basis of any Environmental Claim against the FSB or, to the Seller's Knowledge, against any person or entity whose liability for any Environmental Claim the FSB has retained or assumed either contractually or by operation of law.
	2.13.4.	Without in any way limiting the generality of the foregoing, (i) no polychlorinated biphenyls are or have been used or stored at any property owned or leased by the FSB and (ii) no friable asbestos or asbestos-containing material is present at any property owned or leased by FSB.
2.14.	No Broker's or Finder's Fees.

2.15.	Assets Other Than Real Property.
	2.15.1.	Federal has good marketable title to, or a valid leasehold interest in, all of the FSB assets other than real property shown on the 2000 Balance Sheet, except as to assets disposed of since August 25, 2000 in the ordinary course of business and in a manner consistent with past practice.

To Seller's Knowledge the inventories shown on the 2000 Balance Sheet, and all spare part inventories acquired since such date, consist of items of a quantity and quality usable or saleable in the normal course of business of the FSB, and to Seller's Knowledge the aggregate fair market value of the spare part inventories shown on the 2000 Balance Sheet was, as of such date, at least equal to the dollar amount shown on the 2000 Balance Sheet for such inventories. To Seller's Knowledge all receivables have been collected or are collectible in the amounts shown, less any allowances for doubtful accounts shown on the 2000 Balance Sheet.

	4.3.1.	Subject to terms and conditions herein provided and to the fiduciary duty of each party's Board of Directors and officers, each of the parties agrees to use its best efforts to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective the Agreement and the other transactions contemplated by this Agreement.

Federal and NET.COM will not, directly or indirectly, solicit or authorize the solicitation of, or enter into any agreement or understanding or engage in any discussions with, or disclose any nonpublic information concerning either party to, or otherwise cooperate in any way with, any person or entity with respect to any offer or possible offer from a third party concerning any tender offer, exchange offer, merger, business combination, sale of substantial assets, sale of shares of capital stock, or similar transaction relating to the FSB (an "Acquisition Proposal"). Notwithstanding the foregoing, Federal and NET.COM may discuss, negotiate, enter into an agreement with or furnish information concerning the business, properties or assets of the FSB to any person or entity ("entertain an Acquisition Proposal") if Federal or NET.COM, as the case may be, has received an Acquisition Proposal without prior solicitation and Federal's or NET.COM's outside legal counsel advises that entity's Board of Directors in writing that it would be a breach of their fiduciary responsibilities to refuse to entertain the Acquisition Proposal. In the event that Federal accepts an Acquisition Proposal from any person or entity other than CACI Sub or CACI Parent or that Federal's or NET.COM's Board of Directors fails to approve or withdraws or modifies its approval of the transaction contemplated by this Agreement otherwise than in response to a failure of CACI Sub to satisfy any condition precedent to Federal's obligation to consummate the purchase and sale, NET.COM shall pay to CACI Sub, as compensation for the effort and expense incurred by CACI Sub and CACI Parent in negotiating this Agreement and otherwise preparing to consummate the Acquisition, the sum that equals the greater of (i) the actual costs incurred by CACI Sub and CACI Parent, or (ii) Three Million Dollars ($3,000,000).

4.7.	Acquisition Proposals. Federal and NET.COM will provide CACI Sub and CACI Parent with next business day notice of any Acquisition Proposal that any of them receives from or on behalf of any third party, including in such notice the identity of the offeror and the complete terms of such offer, and will provide CACI Sub and CACI Parent with next business day notice of the receipt of any information that such an offer may be made and any available details with respect to such potential offer.
4.8.	Notification of Certain Matters. At all times until the Closing, each party shall promptly notify the other in writing of the occurrence or failure to occur of any event that (a) would be likely to cause any representation or warranty made by such party in this Agreement to be untrue or inaccurate at, or at any time prior to, the Closing Date, or (b) will or may reasonably be likely to result in the failure to satisfy any of the conditions specified in Article V.
4.9.	Indemnification. Subject to the terms of this Section 4.9, Federal and NET.COM (hereinafter sometimes collectively referred to as the "Indemnifying Parties" and each as "Indemnifying Party") hereby agree to jointly indemnify CACI Sub and CACI Parent and their respective directors, officers, employees, Affiliates, representatives, successors and permitted assigns (collectively "Indemnified Parties") from and against all Losses in connection with or otherwise relating to any of the following:
	(a)	any misrepresentation or inaccuracy in, or breach of, any representation or warranty made by Federal or NET.COM in this Agreement, any Exhibits or Schedules hereto, agreements and documents referred to in this Agreement or the certificates delivered pursuant to this Agreement; and
	(b)	any breach of any covenant, agreement or obligation Federal or NET.COM contained in this Agreement or any Schedule hereto, to be performed by Federal or NET.COM at or prior to Closing; and
	(c)	claims arising solely from the business of the FSB conducted before the Closing, other than claims relating to maintenance of products sold by the FSB.
		4.1.9.	Claims for Indemnification. Whenever any claim shall arise for indemnification hereunder, the Indemnified Party seeking indemnification, shall promptly notify Federal in writing of the claim and the facts believed to constitute the basis for such claim, all with reasonable specificity in light of the facts then known; provided, however, that, failure to so notify the Indemnifying Party shall not discharge the Indemnifying Party from any of its liabilities and obligations hereunder except and to the extent that the failure prejudices the Indemnifying Party, to the extent of such prejudice. The Indemnified Party shall not settle or compromise any claim by a third party for which it is entitled to indemnification hereunder without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld.
		4.9.2.	Defense by Indemnifying Party. In connection with any claims giving rise to indemnity hereunder resulting from or arising out of any claim or legal proceeding by a person who is a third party ("Third Party Claims"), the Indemnifying Party at its sole cost and expense may, upon written notice to the Indemnified Party, assume the defense of any such claim or legal proceeding; provided, however, that the Indemnified Party shall have the right to defend against such claim or legal proceedings at its expense and in such manner as it may deem appropriate, including but not limited to, settling such claim or legal proceedings on such terms as the Indemnified Party may deem appropriate, provided, however, that no such settlement shall be at the Indemnifying Party's expense unless it is approved in advance by the Indemnifying Party. If the Indemnifying Party does not assume the defense of any such claim or legal proceeding resulting therefrom within 30 days after the date of receipt of the notice referred to in Section 4.9.1 above, (a) the Indemnified Party may defend against such claim or legal proceeding at the expense of the Indemnifying Party and in such manner as it may reasonably deem appropriate, including but not limited to, settling such claim or legal proceeding at the expense of the Indemnifying Party and on such terms as the Indemnified Party may reasonably deem appropriate, and (b) the Indemnifying Party shall be entitled to participate in (but not control) the defense of such action, with its counsel and at its own expense. No settlement of any claim or legal proceeding by an Indemnified Party, shall be conclusive as to the amount of the Loss incurred by such Indemnified Party in connection with such claim or legal proceeding.
		4.9.3.	Application of Escrow; Release of Escrow Funds. Any claim by CACI Sub or CACI Parent for indemnification shall be recovered first by disbursement from the Escrow Fund under the provisions of the Escrow Agreement. The Escrow Fund shall be reduced from time to time by disbursement to CACI Sub or CACI Parent in payment of resolved claims for indemnification pursuant to the terms of the Escrow Agreement. The balance of the Escrow Fund in excess of such amount as may be necessary and sufficient to cover the sum of all claims resolved in CACI Sub's or the CACI Parent's favor and not theretofore paid and all claims asserted but not then resolved shall be released on the date that is one year from the Closing Date.
		4.9.4.	Treatment of Indemnification Payments. All indemnification payments under this Section 4.9 shall be deemed adjustments to the Purchase Price.
		4.9.5.	Limitation of Liability. In no event shall the aggregate liability of the Indemnifying Parties exceed an amount equal to twenty per cent (20%) of the amount of the Purchase Price actually paid to Federal.
4.10.	Assignment and Assumption of Contracts
	4.10.1.	Assignment and Assumption of Executory Contracts. At the Closing, Federal will assign to CACI Sub and CACI Sub will assume all responsibilities of Federal related to the provision of Services as defined in the Strategic Alliance Agreement under all executory contracts listed in Schedule 1.1 to which Federal is a party and which may be assigned by Federal to CACI Sub.
	4.10.2.	Performance of Non-Assignable Contracts. With respect to each contract listed in Schedule 1.1 which cannot be assigned at the Closing to CACI Sub for any reason, including any requirement for the consent of the other contracting party or for novation in the case of a contract with the federal government (herein referred to as a "Non-Assignable Contract"), after the Closing CACI Sub shall perform Federal's responsibilities thereunder as to the FSB until assignment (or novation in the case of contracts with the federal government) of such contract has been approved, the contract has been completed, or the contract has otherwise terminated all as provided in the subcontracting agreement substantially in the form of Exhibit E (the "Subcontract").
	4.10.3.	Payments Received from Non-Assignable Contracts. After the Closing, to the extent that CACI Sub performs the relevant services CACI Sub shall be entitled to any and all service related payments received by Federal or NET.COM under any Non-Assignable Contract, and such payments received by Federal or NET.COM shall be deemed to be held by Federal or NET.COM as agent solely for CACI Sub and shall be held in trust for the sole benefit of CACI Sub. Any payments received by Federal in the name of Federal for services related to efforts by the FSB with respect to such Non-Assignable Contracts may be endorsed, deposited, drawn against or otherwise used by CACI Sub as its property and Federal hereby authorizes CACI Sub to sign Federal's name or act in Federal's stead with full power of attorney with regard to such payments.
	4.10.4.	Assignment of Proceeds from all Contracts. As of the Closing and to the extent permitted by law Federal sells, assigns, conveys, grants, and transfers to CACI Sub all of Federal's right, title, and interest in and to all cash and non-cash proceeds from the FSB's receivables or other payment due to Federal for the FSB with respect to the contracts listed in Schedule 1.1, including the Non-Assignable Contracts, and including, without limitation, claims against governmental entities. All such proceeds shall automatically and immediately become the property of CACI Sub at the earliest moment allowed by law and shall be paid to CACI Sub immediately upon receipt by Federal or NET.COM. Any and all proceeds and payments for the FSB received by Federal or NET.COM after the Closing shall be deemed to be held by Federal or NET.COM as agent solely for CACI Sub and shall be held in trust for the sole benefit of CACI Sub.
