ITEM 2.   ACQUISITION OF ASSETS.

On December 6, 2000, CACI International Inc announced that it has completed its acquisition of the federal services business and related assets (the "Federal Services Busines") of N.E.T. Federal, Inc., a subsidiary of Network Equipment Technologies, Inc. (now doing business as net.com). The acquisition became effective at 12:01 a.m. EST on December 2, 2000. The consideration paid to net.com at closing was $25,000,000, and CACI also paid $1,000,000 to First Union Bank to be held in an escrow fund for one year. The purchase price was financed from CACI's line of credit with a group of banks. As described in the Asset Acquisition Agreement, attached hereto as Exhibit 99.2, additional sums will be paid to net.com upon (i) achievement of succession events relating to certain of net.com's contracts with the U.S. Government and (ii) pursuant to a Royalty Agreement that provides for royalty payment based on maintenance revenue earned by CACI following the acquisition.

The Federal Services Business includes approximately 185 employees, and provides secure network services offerings including network engineering and design, implementation, installation and integration, as well as network maintenance and management. Clients include intelligence agencies and major departments within the Federal Government. The acquisition of the Federal Services Business strengthens CACI's ability to serve as a single, focused provider of network services.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors of
Network Equipment Technologies, Inc.:

We have audited the accompanying statement of net assets to be sold of the Federal Services Business (the "Business") of N.E.T. Federal, Inc. ("Federal") (a subsidiary of Network Equipment Technologies, Inc.) ("N.E.T.") as of March 31, 2000, and the related statement of net sales, cost of sales and direct operating expenses for the year then ended. These financial statements are the responsibility of N.E.T.'s management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

The accompanying financial statements were prepared to present the net assets of the Business to be sold pursuant to the Asset Purchase Agreement (the "Agreement") described in Note 1 and net sales, cost of sales and direct operating expenses. Such financial statements are not intended to be a complete financial statement presentation of the Business to be sold and may not be indicative of conditions that would have existed or results that would have occurred had the Business operated as an unaffiliated entity.

In our opinion, such financial statements present fairly, in all material respects, the net assets as of March 31, 2000, of the Business to be sold pursuant to the Agreement, and the net sales, cost of net sales and direct operating expense for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

FEDERAL SERVICES BUSINESS OF N.E.T. FEDERAL, INC.

NOTES TO FINANCIAL STATEMENTS
YEAR ENDED MARCH 31, 2000

1.	BACKGROUND AND BASIS OF PRESENTATION
	N.E.T. Federal, Inc. ("Federal") is a supplier of multiservice wide area networks and associated services used by enterprises, government organizations and carriers worldwide.
	The accompanying financial statements have been prepared for the purpose of presenting the net assets of the Federal Services Business (the "Business") to be sold pursuant to the the Asset Acquisition Agreement (the "Agreement") dated October 18, 2000 between Network Equipment Technologies, Inc. ("N.E.T.") and CACI International Inc ("CACI"), and the net sales, cost of sales and direct operating expenses for the year ended March 31, 2000. The transaction was effective on December 2, 2000. Pursuant to the Agreement, Federal sold to CACI all the tangible and intangible assets constituting the Business, including identified spare parts related to the Business' installed base of products, and CACI assumed and discharged Federal of certain liabilities, as defined in the Agreement, in exchange for consideration totaling $40 million, of which $13 million will be payable contingent upon the earlier of the award of a successor contract, as defined, allowing CACI to continue to provide services and to perform work for DISA, a government agency, or the effective date of an arrangement that permits Federal or its successor to continue to provide services to perform work for DISA substantially similar to the work performed under the AFNET contract for a period extending beyond June 30, 2003. Additional payments of up to $3 million may be made to Federal subject to CACI's ability to continue the work performed by Federal on the AFNET contract beyond June 30, 2003.
	The net assets of the Business consist primarily of the assets and liabilities constituting the government service-related business of Federal. The Business' operations are exclusively conducted in the United States of America.
	Historically, financial statements have not been prepared for the Business and the accompanying financial statements are derived from the historical accounting records of Federal. The financial statements are not intended to be a complete presentation of the Business' financial position, results of operations and cash flows as of the date and for the period presented and may not be indicative of the results after the acquisition by CACI.
	The statement of net sales, cost of sales and direct operating expenses include all revenues and expenses directly attributable to the Business, including allocations for operating costs incurred by N.E.T. or Federal on behalf of the Business. General costs incurred by N.E.T. Corporate (treasury, corporate governance and overheads), interest and income tax expense have not been allocated to the Business as N.E.T. and Federal systems and procedures do not provide for a reasonable cost allocation. Accounts receivable, other assets, accounts payable and accrued liabilities have been reflected in the accompanying statement of net assets to be sold in compliance with the terms of the Agreement. Spare parts inventory and property, plant and equipment have been included on a specific identification basis.
	The accompanying unaudited financial information as of September 30, 2000 and for the six-month periods ended September 30, 2000 and 1999 reflect all adjustments which are, in the opinion of management, necessary to a fair statement of the results of the interim periods presented. Such adjustments are of a normal, recurring nature. Results for interim periods may not be indicative of results for a full year.
2.	SIGNIFICANT ACCOUNTING POLICIES
	Revenue Recognition: Federal recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable and collectibility is reasonably assured. Revenue includes revenue from service contracts, which is recognized ratably over the contract period, and revenue from other services, such as systems integration, installation and training, which is recognized when the service is performed.
	Spares Inventory: The Business inventory cost data has been combined with similar data from other Federal products for purposes of applying the FIFO method of accounting. The Business has been allocated a pro rata portion of the federal FIFO reserve based on the relative inventory levels of Federal. The Company amortizes spares inventory using the declining balance method over seven years.
	Property, Plant and Equipment: Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line method over estimated useful lives of generally three to ten years.
	Impairment of Long-Lived Assets and Long-Lived Assets To Be Disposed of: In accordance with Statement of Financial Accounting Standards ("SFAS") No. 121, "Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed Of", management reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Under SFAS No. 121, recoverability of assets to be held and used is measured by comparing the carrying amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying value of the assets exceeds the fair value of these assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.
	Financial Statement Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such management estimates include, but are not limited to, the allowances for potentially uncollectible accounts receivable, and certain reserves and accruals.
	Credit Risks: Federal's credit evaluation process and the reasonably short collection terms help to mitigate credit risk. Federal typically does not require collateral or other security to support accounts receivable. While Federal does maintain allowances for potential credit losses, actual bad debt losses have not been material or outside of management for potential credit losses, actual bad debt losses have not been material or outside of management's expectations.
	Recently Issued Accounting Standards: In December 1999, the SEC issued Staff Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in Financial Statements," which summarizes certain of the SEC staff's views in applying generally accepted accounting principles to revenue recognition in financial statements. Federal believes that its revenue recognition policy complies with the provisions of SAB No. 101.

The company also offers existing resources such as its Vision & Solution Center, a state-of-the-art technical facility that hosts a number of client networks and provides resources to evaluate alternative network solutions.

CACI Chairman and CEO Dr. J.P.

2.9.	Litigation.

Federal has not been notified in writing or otherwise by any taxing authority of any pending actions, claims, suits or assessments for any tax deficiency.
2.11.	Employee Benefit Plans; Compliance with ERISA.
	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. With respect to all the Federal Plans, Federal and every Affiliate are in material compliance with all requirements prescribed by all statutes, regulations, orders or rules currently in effect, and have in all material respects performed all obligations required to be performed by them 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.

(i) Federal is in compliance in all material respects with all applicable laws respecting employment, consulting, employment practices, wages, hours, and terms and conditions of employment with respect to the FSB; (ii) Federal is not a party to any collective bargaining agreement or other contract or agreement with any labor organization or other representative of any of the employees of Federal; (iii) there is no labor strike, dispute, slowdown, work stoppage, lockout or other labor controversy in effect, that is pending or, to Seller's Knowledge, threatened against or otherwise affecting the FSB, and the FSB has not experienced any labor controversy within the past three years; (iv) no labor organization has claimed to represent any of the employees of Federal for collective bargaining, and no one has sought any election or other proceeding to establish a collective bargaining representation; (v) Federal has not closed any plant or facility, effectuated any layoffs of employees or implemented any early retirement, separation or window program relating to the FSB at any time from or after March 31, 2000, nor has Federal planned or announced any action or program for the future with respect to which the FSB has any material liability; and (vi) Federal is in compliance in all material respects with its obligations relating to the FSB pursuant to the Worker Adjustment and Retraining Notification Act of 1988, and all other notification and bargaining obligations arising under any collective bargaining agreement or statute relating to employment; provided, however, that nothing in this Section 2.12 shall be construed as any representation or warranty relating to the Code or ERISA.
2.13.	Environmental.
	2.13.1.	(i) Federal is in full compliance in all material respects with all applicable Environmental Laws applicable to the FSB, (ii) Federal has not received any communication (written or oral), whether from a governmental authority, employee, or any other person that alleges that Federal is not in such full compliance, (iii) to Seller's Knowledge there are no circumstances that may prevent or interfere with such full compliance in the future, and (iv) all permits and other governmental authorizations currently held by Federal for the FSB pursuant to the Environmental Laws are in full force and effect and no other permits are required by Federal.
	2.13.2.	To Seller's Knowledge, there is no Environmental Claim pending or threatened against or involving the FSB or against any person or entity whose liability for any Environmental Claim the FSB has retained or assumed either contractually or by operation of law.
	2.13.3.	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. Neither NET.COM nor Federal has paid or become obligated to pay any fee or commission to any broker, finder, financial advisor or intermediary in connection with the transactions contemplated by this Agreement or any other acquisition transaction involving the FSB, except for Quarterdeck Investment Partners.
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. Except as described in Schedule 2.15, none of such assets is subject to any mortgage, pledge, lien, security interest, lease or other encumbrance, except as reflected in the 2000 Balance Sheet or except for those incurred or made in the ordinary course of business that do not materially impair the usefulness of such assets or properties in the conduct of the business of the FSB.
	2.15.2.	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. To Seller's Knowledge, all plant and equipment and personal property owned by Federal included in the Assets (other than fully-depreciated Assets) are in good operating condition and repair.

	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.
