Article 2: REPRESENTATIONS AND WARRANTIES OF CENTECH

CENTECH represents and warrants to CACI and Parent as follows:


2.1	Corporate Status of CENTECH. CENTECH is a corporation duly organized, validly existing and in good standing under the laws of the District of Columbia. CENTECH is duly qualified to do business as a foreign corporation and is in good standing in all jurisdictions in which the character of the properties owned, leased or operated by it or the nature of the business transacted by it makes such qualification necessary, except where failure to be so qualified would not have a materially adverse effect on the financial condition, business, assets, properties or results of operations of CENTECH.


2.2	Subsidiaries. CENTECH has no Subsidiaries.


2.3	Authority for Agreement . CENTECH has the full corporate power to own, lease and operate its properties and to conduct its business as currently owned, leased, operated and conducted and to execute, deliver, and perform this Agreement and to carry out its obligations hereunder. The execution, delivery and performance of this Agreement and the other transactions contemplated hereby have been duly and validly authorized by CENTECH's Board of Directors and its stockholders, and no other corporate proceedings on the part of CENTECH are necessary to authorize the execution, delivery and performance of this Agreement and the other transactions contemplated hereby. CENTECH's Board of Directors has determined that, subject to the fulfillment of the terms and conditions of this Agreement, the transactions contemplated hereby are in the best interest of the stockholders of CENTECH. This Agreement has been duly executed and delivered by CENTECH and constitutes a valid and binding obligation of CENTECH, enforceable against CENTECH in accordance with its terms.


2.4	No Default or Violation .

2.9	Litigation


	2.9.1	To the best of CENTECH's knowledge, there is no investigation, inquiry or review by any governmental entity or authority with respect to CENTECH pending or, to the best of CENTECH's knowledge, threatened, nor has any governmental entity indicated to CENTECH an intention to conduct the same;


	2.9.2	there is no claim, action, suit, arbitration, or proceeding pending or, to the best of CENTECH's knowledge, threatened against or affecting CENTECH or any of its assets or properties, at law or in equity, or before any court, arbitrator, or governmental entity or authority, that either singly or in the aggregate may have any material adverse effect on the financial condition, business, operations, properties or prospects of CENTECH;


	2.9.3	there is no claim, action, suit, labor dispute, investigation or proceeding of any kind, pending or, to the best of CENTECH's knowledge, threatened, that involves, affects or relates to CENTECH or any of its officers, employees or directors in connection with the business and affairs of CENTECH that either singly or in the aggregate may have any material adverse effect on the business, operations, assets, financial condition, results of operations, or properties of CENTECH; and

2.10	Tax Matters . CENTECH has complied in all material respects with the requirements for filing federal, state, local and foreign tax returns and reports required to be filed by it or on its behalf. All taxes shown by the returns to be due and payable have been paid or are reflected as a liability on the CENTECH balance sheets included in the CENTECH Financial Statements. All tax returns of CENTECH that have been audited by any governmental authority since December 31, 1997 are identified on Schedule 2.10 along with the respective authority; CACI has been provided with a copy of all returns and any assessments resulting from such examinations and all assessments, penalties and interest have been paid in full. CENTECH has not been notified in writing or otherwise by any taxing authority of any pending actions, claims, suits or assessments for any tax deficiency. The accruals for taxes reflected on the 1999 Balance Sheet are adequate under generally accepted accounting principles for all unpaid federal, state, local or foreign taxes (including but not limited to interest, charges, fees, levies, or other assessments, gross receipts, excise and franchise taxes and penalties, if any, thereon) due or that will become due for any period commencing prior to the date of the Closing. CENTECH has no material liability, contingent or otherwise, for unpaid federal, state, local or foreign taxes (including but not limited to interest, charges, fees, levies or other assessments, gross receipts, excise and franchise taxes and penalties, if any, thereon) due or that will become due for any period commencing prior to the date of the 1999 Balance Sheet that is not reflected on the 1999 Balance Sheet. CENTECH is not a party to any tax indemnity or tax sharing agreement.


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 persons employed by CENTECH and maintained at any time by CENTECH 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 CENTECH (as defined for purposes of Section 414(b), (c) and (m) of the Code) (collectively, the "CENTECH Plans"). CENTECH has made available to CACI true, correct and complete copies of all CENTECH 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 CENTECH Plans, CENTECH has made available the latest Forms 5500. Neither CENTECH nor any Affiliate has ever been obligated to contribute to any "multi-employer plan," as defined in Section 3(37) of ERISA. Neither CENTECH nor any Affiliate has incurred any "withdrawal liability" calculated under Section 4211 of ERISA and, to the best knowledge of CENTECH, there has been no event or circumstance which would cause them to incur any such liability. Neither CENTECH nor any Affiliate has ever maintained a CENTECH Plan providing health or life insurance benefits to former employees. No plan previously maintained by CENTECH 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 such CENTECH Plan, and no liability to the Pension Benefit Guaranty Corporation has been incurred. With respect to all the CENTECH Plans, CENTECH 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. Neither CENTECH nor any Affiliate, nor any of their directors, officers, employees or agents, nor any trustee or administrator of any trust created under the CENTECH Plans, have engaged in or been a party to any "prohibited transaction" as defined in Section 4975 of the Code and Section 406 of ERISA which could subject CENTECH or CACI or their affiliates, directors or employees or the CENTECH Plans or the trusts relating thereto or any party dealing with any of the CENTECH Plans or trusts to any material tax or penalty on "prohibited transactions" imposed by Section 4975 of the Code. Neither the CENTECH 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 CENTECH 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; and, to the best knowledge of CENTECH, nothing has occurred since the date of such determination letters which might cause the loss of such qualification or exemption. With respect to each CENTECH Plan which is a qualified profit sharing or stock bonus plan, all employer contributions accrued for plan years ending prior to the Closing Date under the CENTECH Plan terms and applicable law have been made or accrued.


	2.11.3	There are no actions, suits or claims pending or, to the best knowledge of CENTECH, threatened, with respect to any of the CENTECH Plans, and there are no outstanding written requests, other than routine requests for information concerning such CENTECH Plans, by participants, beneficiaries or any government agency. All of the liabilities with respect to all of the CENTECH Plans are accurately reflected in the 1999 Balance Sheet.


2.12	Employment-Related Matters . (i) CENTECH is in compliance in all material respects with all applicable laws respecting employment, consulting, employment practices, wages, hours, and terms and conditions of employment; (ii) CENTECH 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 CENTECH; (iii) there is no labor strike, dispute, slowdown, work stoppage, lockout or other labor controversy in effect, that is pending or, to the knowledge of CENTECH, threatened against or otherwise affecting CENTECH and CENTECH has not experienced any labor controversy within the past three years; (iv) no labor organization has claimed to represent any of the employees of CENTECH for collective bargaining, and no one has sought any election or other proceeding to establish a collective bargaining representation; (v) CENTECH has not closed any plant or facility, effectuated any layoffs (except for layoffs due to reductions in work at certain facilities, which have not at any time involved a sufficient number of employees to impose any obligation on CENTECH under the Worker Adjustment and Retraining Notification Act) of employees or implemented any early retirement, separation or window program at any time from or after January 1, 1999, nor has CENTECH planned or announced any action or program for the future with respect to which CENTECH has any material liability; and (vi) CENTECH is in compliance in all material respects with its and their obligations 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) CENTECH is in full compliance in all material respects with all applicable Environmental Laws (as hereinafter defined in Section 7.1), (ii) CENTECH has not received any communication (written or oral), whether from a governmental authority, employee, or any other person that alleges that CENTECH is not in such full compliance, (iii) to CENTECH'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 CENTECH pursuant to the Environmental Laws are in full force and effect and no other permits are required by CENTECH.


	2.13.2	To the knowledge of CENTECH, there is no Environmental Claim pending or threatened against or involving CENTECH or against any person or entity whose liability for any Environmental Claim CENTECH 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 CENTECH or by any other person to CENTECH's knowledge that could form the basis of any Environmental Claim against CENTECH or, to the knowledge of CENTECH, against any person or entity whose liability for any Environmental Claim CENTECH 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 by CENTECH at any storage facility leased by CENTECH and no polychlorinated biphenyls are or have been used or stored at any other property leased by CENTECH and (ii) no friable asbestos or asbestos-containing material is present at any property leased by CENTECH.


2.14	No Broker's or Finder's Fees . Except as described in Schedule 2.14, CENTECH has not 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 CENTECH.


2.15	Assets Other Than Real Property .


	2.15.1	Except as set forth on Schedule 2.15, CENTECH has good marketable title to, or a valid leasehold interest in, all of the assets other than real property shown on the 1999 Balance Sheet, except as to assets disposed of since December 31, 1999 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 1999 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 CENTECH.


	2.15.2	The inventories shown on the 1999 Balance Sheet, and all inventories acquired since such date, consist of items of a quantity and quality usable or saleable in the normal course of business of CENTECH, and the aggregate fair market value of the inventories shown on the 1999 Balance Sheet was, as of such date, at least equal to the dollar amount shown on the 1999 Balance Sheet for such inventories. All receivables have been collected or are collectible in the amounts shown, less any allowances for doubtful accounts shown on the 1999 Balance Sheet. To the best of CENTECH's knowledge, all plant and equipment and personal property owned by CENTECH and included in the Assets are in good operating condition and repair (other than fully-depreciated Assets).


2.16	Real Property .


	2.16.1	CENTECH does not own any real property.


	2.16.2	Schedule 2.16 sets forth a true, correct and complete list as of the date hereof of all leases of real property useful to CENTECH to which CENTECH is a party (the "Leases"); CENTECH is not a party to any ground lease. True, correct and complete copies of the Leases, and all amendments, modifications and supplemental agreements thereto (which are identified on Schedule 2.16), have previously been delivered by CENTECH to CACI. The Leases grant leasehold estates free and clear of all mortgages, liens, claims, charges, security interests, encumbrances or other restrictions or limitations whatsoever granted by or caused by the actions of CENTECH, and CENTECH enjoys a right of quiet possession as against any lien or other encumbrance on the property. The Leases are in full force and effect, are binding and enforceable against each of the parties thereto in accordance with their respective terms and have not been modified or amended since the date of delivery to CACI. No party to any Lease has sent written notice to the other claiming that such party is in default thereunder, which remains uncured. There has not occurred any event that would constitute a breach of or default in the performance of any material covenant, agreement or condition contained in any Lease, nor to CENTECH's knowledge has there occurred any event that with the passage of time or the giving of notice or both would constitute such a breach or material default. CENTECH is not obligated to pay any leasing or brokerage commission relating to any Lease and will not have any enforceable obligation to pay any leasing or brokerage commission upon the renewal of any Lease. No material construction, alteration or other leasehold improvement work with respect to any of the Leases remains to be paid for or to be performed by CENTECH.


	2.16.3	CENTECH is not in violation of any law, regulation or ordinance (including, without limitation, laws, regulations or ordinances relating to building, zoning, environmental, city planning, land use or similar matters) relating to its respective real properties, whether owned or leased, where such violation has or could reasonably be expected to have a material adverse effect on the ability of CACI to use and employ the Assets in substantially the way that CENTECH now does. There are no proceedings materially affecting any of such real properties that are pending or, to the best of CENTECH's knowledge, threatened and that could have a materially adverse effect on the present or future use of any such real property for the purpose for which it is used or the purpose for which it is intended to be used. All buildings, structures and fixtures used by CENTECH in the conduct of the business of CENTECH, are, to the best of CENTECH's actual knowledge without special inquiry, in good operating condition and repair and are insured with coverages that are usual and customary for similar properties and similar businesses.


	2.16.4	CENTECH has access to its respective properties, whether owned or leased, by way of public ways or to the best of CENTECH's actual knowledge without special inquiry, valid easements or rights of way sufficient to conduct the business of CENTECH as presently conducted.


2.17	Agreements, Contracts and Commitments .

CACI and Parent jointly and severally represent and warrant to CENTECH as follows:


3.1	Corporate Status of CACI and its Subsidiaries . CACI and Parent are corporations duly organized, validly existing and in good standing under the laws of Delaware. CACI and Parent are duly qualified to do business as foreign corporations and are in good standing in all jurisdictions in which the character of the properties owned, leased or operated by each or the nature of the business transacted by each makes such qualification necessary, except where failure to be so qualified would not have a materially adverse effect on the business, operations, assets, financial condition, results of operations, properties or prospects of Parent and its Subsidiaries considered as a whole.


3.2	Subsidiaries . Parent has 15 significant Subsidiaries: They are listed in Exhibit 21 to Parent's Annual Report (Form 10-K) for the year ended June 30, 1999, as filed with the SEC. Parent owns all of the outstanding shares of capital stock of its Subsidiaries, free and clear of all liens, charges, pledges, security interests, encumbrances, and other restrictions and agreements with respect thereto. All outstanding shares of capital stock have been duly authorized and validly issued, were not issued in violation of any person's preemptive rights, and are fully paid and nonassessable. There are no outstanding subscriptions, options, warrants, conversion rights or other rights, securities, agreements or commitments obligating Parent or any of its Subsidiaries to issue, sell or otherwise dispose of any shares of capital stock, or any securities or obligations convertible into, or exercisable or exchangeable for, any shares of capital stock, of any of Parent's Subsidiaries. Other than shares of its Subsidiaries, Parent does not own, directly or indirectly, any capital stock or other equity interest in any business organization, entity or enterprise.

CACI and Parent have the full corporate power to own, lease and operate their properties and to conduct their businesses as currently owned, leased, operated and conducted and to execute, deliver, and perform this Agreement and to carry out their obligations hereunder. The execution, delivery and performance of this Agreement and the other transactions contemplated hereby have been duly and validly authorized by the Boards of Directors of CACI and Parent and no other corporate proceedings on the part of CACI or Parent including, without limitation, stockholder approval, are necessary to authorize the execution, delivery and performance of this Agreement and the other transactions contemplated hereby. This Agreement has been duly executed and delivered by CACI and Parent and constitutes a valid and binding obligation of each of them, enforceable against each of them in accordance with its terms.


3.4	No Default or Violation . The execution, delivery and performance of this Agreement and the other transactions contemplated hereby do not and will not (i) conflict with or result in a violation of any provision of the Certificate of Incorporation or By-Laws or other organizational documents of Parent or any of its Subsidiaries, or (ii) with or without the giving of notice or the lapse of time, or both, conflict with, or result in any violation or breach of or constitute a default under, or require the consent of any other party to, or result in any right to accelerate or the creation of any lien, charge or encumbrance pursuant to, or right of termination under, any provision of any note, mortgage, indenture, lease, agreement or other instrument, permit, concession, grant, franchise, license, judgment, order, decree, statute, law, ordinance, rule or regulation to which Parent or any of its Subsidiaries is a party or by which any of them or any of their assets or properties may be bound or which is applicable to any of them or any of their assets or its properties. No authorization, consent, approval, license, order, or permit of, or declaration of, or filing with or notice to, any governmental body or authority or any other person or entity is necessary for the execution and delivery of this Agreement by CACI or Parent or the consummation by CACI and Parent of the other transactions contemplated hereby or to enable Parent and its Subsidiaries to continue to conduct their business after the Closing in a manner consistent in all material respects with that in which they are currently conducted.

Each of the balance sheets included in the CACI Reports (including any related notes and schedules) fairly presents the consolidated financial position of the Parent and its consolidated subsidiaries, including CACI, as of its date and the other financial statements included in the CACI Reports (including any related notes and schedules) fairly present the consolidated results of operations or other information included therein of the Parent and its consolidated subsidiaries, including CACI, for the periods or as of the dates therein set forth, in each case in accordance with generally accepted accounting principles consistently applied during the periods involved. None of the CACI Reports contained as of its date any untrue statement of a material fact or any omission to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or (b) is required to be amended or supplemented as of the date of this Agreement. Since December 31, 1999, the Parent has filed all required forms, reports and documents with the SEC required to be filed by it pursuant to the federal securities laws and the rules and regulations thereunder, all of which have complied as of their respective filing dates in all material respects with all applicable requirements of the Securities Act, the Exchange Act and the rules and regulations under each such act.

CACI and CENTECH shall consult each other before issuing any press release or other public announcement referring to this Agreement or the terms and conditions of the transactions contemplated hereby.


4.5	Restricted Activities and Transactions . CENTECH 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 (an "Acquisition Proposal"). Notwithstanding the foregoing, the party may discuss, negotiate, enter into an agreement with or furnish information concerning its business, properties or assets to any person or entity ("entertain an Acquisition Proposal") if that party has received an Acquisition Proposal without prior solicitation and the party's outside legal counsel advises the party'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 CENTECH accepts an Acquisition Proposal from any person or entity other than CACI or that CENTECH's Board of Directors fails to approve or withdraws or modifies its approval of the transaction contemplated by this Agreement except in response to a failure of CACI to satisfy any condition precedent to CENTECH's obligation to consummate the purchase and sale, CENTECH shall pay to CACI the sum of $300,000 as compensation for the effort and expense incurred by CACI in negotiating this Agreement and otherwise preparing to consummate the transactions contemplated hereby.

Each party will provide the other party with same-day notice of any Acquisition Proposal that the party 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 the other party with same-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.


4.7	Notification of Certain Matters . At all times until the Effective Time, 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 Effective Time, or (b) will or may result in the failure to satisfy any of the conditions specified in Article V.


4.8	Indemnification . Subject to the terms this Section 4.8, CENTECH (hereinafter sometimes referred to as the "Indemnifying Party") hereby agrees to indemnify CACI and its directors, officers, employees, Affiliates, representatives, successor and 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 CENTECH in this Agreement or any Exhibits or Schedules hereto or the certificates delivered pursuant to this Agreement; and


		(b)	any breach of any covenant, agreement or obligation CENTECH contained in this Agreement, or any Exhibits or Schedules hereto, to be performed by CENTECH at or prior to Closing.


	4.8.1	Claims for Indemnification . Whenever any claim shall arise for indemnification hereunder, the Indemnified Party seeking indemnification, shall promptly notify CENTECH 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's ability to raise a substantial defense to the claim and except to the extent of any liabilities or obligations caused by or arising out of such failure to notify. 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. The Indemnifying Party may settle any matter (in whole or in part) without the Indemnified Party's prior consent, if such settlement includes a complete and unconditional release of the Indemnified Party.


	4.8.2	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 4.8.1 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 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.


	4.8.3	Application of Escrow; Release of Escrow Funds . Any claim by CACI or 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 or Parent in payment of resolved claims for indemnification and by disbursement to CENTECH of the following amounts at the following times:


		(a)	The amount of Two Hundred Fifty Thousand Dollars ($250,000) or such lesser amount as may be necessary so that the undisbursed balance of the Escrow Fund is sufficient to cover the sum of all claims resolved in CACI's or the Parent's favor and not theretofore paid and all claims asserted but not then resolved (the "Minimum Escrow Balance") shall be released on the date that is six months after the Novation Date; and


		(b)	The amount of the Escrow Fund in excess of the then Minimum Escrow Balance shall be released on the date that is one year after the Novation Date.


	4.8.4	Limitation of Liability . Notwithstanding any other provision of this Agreement, the Indemnifying Party shall have no liability to the Indemnified Party under this Section 4.8 until the aggregate amount of all Losses claimed by the Indemnified Party exceeds Seventy-five Thousand Dollars ($75,000) and then only for Losses in excess of that amount. In no event shall CENTECH be liable for any amount in excess of the aggregate Purchase Price, except to the extent of Losses arising from a fraudulent or knowing violation on the part of CENTECH.


	4.8.5	Treatment of Indemnification Payments . All indemnification payments under this Section 4.8 shall be deemed adjustments to the Merger Price.


4.9	Benefit Plans


	4.9.1	All employees of CENTECH who become employees of CACI from and after the Closing shall receive full credit for any service which they performed for and on behalf of CENTECH, for purposes of eligibility to participate, accrual of benefits, and vesting schedules under any of CACI's employee benefit plans or programs.


	4.9.2	Upon presentation of satisfactory confirming documentation, for calendar year 2000, all employees of CENTECH who become employees of CACI and who choose to be covered under CACI's PPO/Indemnity Group Health Insurance Plan shall receive full credit for any deductible or out-of-pocket expenses which they have incurred under the CENTECH group health plan.


	4.9.3	All employees of CENTECH who become employees of CACI shall be able to carry over all leave which they had accrued, but not used, prior to the Closing.

If any CENTECH employee continues to occupy and use any of the Holdover Space after the Holdover Period, CENTECH will be liable to CACI for compensation in an amount equal to three times the monthly rent for which CACI is obligated with respect to the Silver Spring premises, prorated for the portion of the premises constituting the Holdover Space and the number of days of occupancy after the Holdover Period. CACI may assert CENTECH's liability for compensation as an indemnification claim against the Escrow Fund. In no event may any employee of CENTECH occupy or use any part of the Silver Spring premises after the Holdover Period.


4.11	Assignment and Assumption of Contracts


	4.11.1	Assignment and Assumption of Executory Contracts . At closing, CENTECH will assign to CACI, and CACI will assume all responsibilities of CENTECH under, all executory contracts listed in Schedule 1.1 to which CENTECH is a party and which may be assigned by CENTECH to CACI.

Arlington, Va., April 3, 2000 -- CACI International Inc (NASDAQ: CACI) announced today that it had completed the purchase of substantially all of the assets of Century Technologies, Incorporated (CENTECH), a privately-held information technology (IT) company based in Maryland. The acquisition augments CACI capabilities in network services and e-commerce, fits CACI's strategic plan for growth in the state & local market, and complements current offerings for federal and commercial clients. The terms of the acquisition were not disclosed. The transaction was financed through bank borrowings.

CENTECH is headquartered in Silver Spring, Maryland, with facilities in Texas, Ohio, and Oklahoma. The company provides full-service IT solutions for networking and telecommunications, e-commerce, geospatial technologies, and software engineering. The company's client base includes the federal government, state governments, and the military services. CENTECH revenues for its fiscal year ending March 31, 1999 were $23.7 million, up 16% from 1998.

CENTECH offerings include high-level IT solutions for network services and e-commerce. For example, CENTECH supports, operates, and maintains networks and network systems infrastructure for the U.S. Department of State.

This CENTECH support ranges across the entire spectrum of IT activities, including systems design and development, implementation, and EBT field support.

CACI Chairman and CEO Dr. J.P. (Jack) London said, "CENTECH is a terrific fit with our strategic plans. I anticipate CACI's acquisition of CENTECH to contribute to rapid growth in our network services and e-commerce lines of business. CENTECH also brings an outstanding culture of client responsiveness that perfectly complements CACI's own focus on quality client service. We expect the transaction to be accretive immediately."

There are statements made above which do not address historical facts and, therefore, could be interpreted to be forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995. Such statements are subject to factors that could cause actual results to differ materially from anticipated results. The factors that could cause actual results to differ materially from those anticipated include, but are not limited to, the following: changes in interest rates; the risks and uncertainties associated with client interest in and purchases of new products and/or services; continued funding of U.S. Government or other public sector projects in the event of a priority need for funds; government contract procurement (such as bid protest) and termination risks; individual business decisions of our clients; paradigm shifts in technology; competitive factors such as pricing pressures and/or competition to hire and retain employees; our ability to complete acquisitions and/or divestitures appropriate to achievement of our strategic plans; and other risks described in the Company's Securities and Exchange Commission filings.
