This Confirmation shall supplement, form a part of, and be subject to an agreement in the form of the 2002 ISDA Master Agreement (the “Agreement”) as if Dealer and Company had executed an agreement in such form (but without any Schedule except for the election of the laws of the State of New York as the governing law) on the Trade Date. In the event of any inconsistency between provisions of that Agreement and this Confirmation, this Confirmation will prevail for the purpose of the Transaction to which this Confirmation relates. The parties hereby agree that no Transaction other than the Transaction to which this Confirmation relates shall be governed by the Agreement.

		shall make adjustments, if applicable, to the Daily Number of Warrants or shall reduce such Daily Number of Warrants to zero for which such day shall be an Expiration Date and shall designate a Scheduled Trading Day or a number of Scheduled Trading Days as the Expiration Date(s) for the remaining Daily Number of Warrants or a portion thereof for the originally scheduled Expiration Date; and provided further that if such Expiration Date has not occurred pursuant to this clause as of the eighth Scheduled Trading Day following the last scheduled Expiration Date under this Transaction, the Calculation Agent shall have the right to declare such Scheduled Trading Day to be the final Expiration Date and the Calculation Agent shall determine its good faith estimate of the fair market value for the Shares as of the Valuation Time on that eighth Scheduled Trading Day or on any subsequent Scheduled Trading Day, as the Calculation Agent shall determine using commercially reasonable means.

Notwithstanding the foregoing, if (i) any Expiration Date is a Disrupted Day and (ii) the Calculation Agent determines that such Expiration Date shall be an Expiration Date for fewer than the Daily Number of Warrants, as described above, then the Settlement Price for the relevant Valuation Date shall be the volume-weighted average price per Share on such Valuation Date on the Exchange, as determined by the Calculation Agent based on such sources as it deems appropriate using a volume-weighted methodology, for the portion of such Valuation Date for which the Calculation Agent determines there is no Market Disruption Event.
Settlement Date(s):		As determined in reference to Section 9.4 of the Equity Definitions, subject to Section 9(n)(i) hereof.

The representations and warranties of Company set forth in Section 3 of the Purchase Agreement (the “Purchase Agreement”) dated as of May 10, 2007 between Company and X.X. Xxxxxx Securities Inc. and Banc of America Securities LLC as representatives of the Initial Purchasers party thereto are true and correct and are hereby deemed to be repeated to Dealer as if set forth herein. Company hereby further represents and warrants to Dealer that:

(a) Company has all necessary corporate power and authority to execute, deliver and perform its obligations in respect of this Transaction; such execution, delivery and performance have been duly authorized by all necessary corporate action on Company’s part; and this Confirmation has been duly and validly executed and delivered by Company and constitutes its valid and binding obligation, enforceable against Company in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights to indemnification and contribution hereunder may be limited by federal or state securities laws or public policy relating thereto.

(b) Neither the execution and delivery by Company of this Confirmation nor the incurrence or performance of obligations of Company hereunder will result in a breach or violation of the

7

certificate of incorporation or by-laws of Company, or any applicable law or regulation, or any order, writ, injunction or decree of any court or governmental authority or agency, or result in the creation of any lien (other than any lien existing or arising under the Credit and Security Documents (as defined below)) under, or (except as may result from any Credit Agreement Matters (as defined below) with respect to the performance of obligations of Company hereunder) breach or constitute a default under any agreements and contracts of Company and its significant subsidiaries filed as exhibits to Company’s Annual Report on Form 10-K for the year ended June 30, 2006, and to Company’s Quarterly Reports on Form 10-Q for the quarters ended September 30, 2006, December 31, 2006 and March 31, 2007, as updated by any exhibits to any Current Report on Form 8-K filed after March 31, 2007 and on or before the date hereof. As used herein, “Credit and Security Documents” means the Credit Agreement dated as of May 3, 2004, as amended by the First Amendment dated as of May 18, 2005 and by the Second Amendment dated as of (or about) May 9, 2007 (as so amended, the “Credit Agreement”), by and among the Company, the Guarantors identified therein, the Lenders identified therein and Bank of America, N.A., as Administrative Agent, and the Security Agreement (as defined therein) entered into in connection therewith. As used herein, “Credit Agreement Matters” means (i) the restrictions set forth in Section 8.06(d) of the Credit Agreement on Company’s ability to make Restricted Payments (as defined in the Credit Agreement) as provided in such section, (ii) the restrictions set forth in Section 8.06(g) of the Credit Agreement on the Company’s ability to make cash payments pursuant to this Confirmation upon or following the conversion of any of the Convertible Notes (or any portion of Company’s obligations thereunder) as provided in such section, and (iii) any potential cross default that might arise under Section 9.01(e)(iii) of the Credit Agreement based on the occurrence of an early termination date hereunder as provided in such section.

(c) No consent, approval, authorization, or order of, or filing with, any United States governmental agency or body or any court is required in connection with the execution, delivery or performance by Company of this Confirmation, except such as have been obtained or made and such as may be required under the Securities Act of 1933, as amended (the “Securities Act”), the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or state securities laws.

(d) The Shares of Company initially issuable upon exercise of the Warrant by the net share settlement method (the “Warrant Shares”) have been reserved for issuance by all required corporate action of Company. The Warrant Shares have been duly authorized and, when delivered against payment therefor (which may include Net Share Settlement in lieu of cash) and otherwise as contemplated by the terms of the Warrant following the exercise of the Warrant in accordance with the terms and conditions of the Warrant, will be validly issued, fully-paid and non-assessable, and the issuance of the Warrant Shares will not be subject to any preemptive or similar rights imposed by Company’s certificate of incorporation or by-laws or the Delaware General Corporation Law.

Company is a corporation, partnership, proprietorship, organization, trust or other entity and:

(A) Company has total assets in excess of USD 10,000,000;

(C) Company has a net worth in excess of USD 1,000,000 and has entered into this Agreement in connection with the conduct of Company’s business or to manage the risk associated with an asset or liability owned or incurred or reasonably likely to be owned or incurred by Company in the conduct of Company’s business.

8

(f) Company and each of its affiliates is not, on the date hereof, in possession of any material non-public information with respect to Company.

9. Other Provisions:

(a) Opinions. Company shall deliver an opinion or opinions of counsel, dated as of the Trade Date, to Dealer with respect to the matters set forth in Sections 8(a) through (d) of this Confirmation, subject to the limitations and exceptions set forth in the Purchase Agreement.

(b) Amendment. If the Initial Purchasers party to the Purchase Agreement exercise their right to receive additional Senior Subordinated Convertible Notes due 2014, (the “Convertible Notes”) pursuant to the Initial Purchasers’ option to purchase additional Convertible Notes, then, at the discretion of Company, Dealer and Company will either enter into a new confirmation or amend this Confirmation to provide for additional Warrants in proportion to such additional Convertible Notes (but on pricing terms acceptable to Dealer and Company) (such additional confirmation or amendment to this Confirmation to provide for the payment by Dealer to the Company of the additional premium related thereto).

(c) Repurchase Notices. Company shall, on any day on which Company effects any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a “Repurchase Notice”) on such day if following such repurchase, the quotient of (x) the product of (a) the Number of Warrants and (b) the Warrant Entitlement divided by (y) the number of Company’s outstanding Shares (such quotient expressed as a percentage, the “Warrant Equity Percentage”) would be (i) greater than 6.0% or (ii) 0.5% greater than the Warrant Equity Percentage included in the immediately preceding Repurchase Notice. Company agrees to indemnify and hold harmless Dealer and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all losses (including losses relating to Dealer’s hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to this Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person actually may become subject to, as a result of Company’s failure to provide Dealer with a Repurchase Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any reasonable legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person, such Indemnified Person shall promptly notify Company in writing, and Company, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Company may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding. Company shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Company agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Company shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then Company under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities. The

9

remedies provided for in this paragraph are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity. The indemnity and contribution agreements contained in this paragraph shall remain operative and in full force and effect regardless of the termination of this Transaction.

(d) Regulation M. Company is not on the date hereof engaged in a distribution, as such term is used in Regulation M under the Exchange Act, of any securities of Company, other than a distribution meeting the requirements of the exception set forth in Rules 101(b)(10) and 102(b)(7) of Regulation M. Company shall not, until the second Scheduled Trading Day immediately following the Trade Date, engage in any such distribution.

(e) No Manipulation. Company is not entering into this Transaction to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) or otherwise in violation of the Exchange Act.

(f) Board Authorization. This Transaction was approved by Company’s board of directors, and was publicly announced, solely for the purposes stated in its public disclosure. Company further represents that there is no internal policy, whether written or oral, of Company that would prohibit Company from entering into any aspect of this Transaction, including, but not limited to, the issuance of Shares to be made pursuant hereto.

(g) Transfer or Assignment. Company may not transfer any of its rights or obligations under this Transaction without the prior written consent of Dealer. Dealer may, without Company’s consent, transfer or assign all or any part of its rights or obligations under this Transaction to any third party. If after Dealer’s commercially reasonable efforts, Dealer is unable to effect such a transfer or assignment on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer of a sufficient number of Warrants to reduce (i) Dealer’s “beneficial ownership” (within the meaning of Section 13 of the Exchange Act and rules promulgated thereunder) to 7.5% of Company’s outstanding Shares or less or (ii) the Warrant Equity Percentage to 14.5% or less, Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion (the “Terminated Portion”) of this Transaction, such that (i) its “beneficial ownership” following such partial termination will be equal to or less than 7.5% or (ii) the Warrant Equity Percentage following such partial termination will be equal to or less than 14.5%. In the event that Dealer so designates an Early Termination Date with respect to a portion of this Transaction, a payment shall be made pursuant to Section 6 of the Agreement as if (i) an Early Termination Date had been designated in respect of a Transaction having terms identical to this Transaction and a Number of Warrants equal to the Terminated Portion, (ii) Company shall be the sole Affected Party with respect to such partial termination and (iii) such Transaction shall be the only Terminated Transaction (and, for the avoidance of doubt, the provisions of paragraph 9(m) shall apply to any amount that is payable by Dealer to Company pursuant to this sentence). Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities to or from Company, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities and otherwise to perform Dealer’s obligations in respect of this Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Company to the extent of any such performance. Any transfer, assignment or early termination of this Transaction by Dealer shall be in full compliance with the Securities Act and other applicable laws.

(h) Early Unwind. In the event the sale of Convertible Notes is not consummated with the initial purchasers for any reason by the close of business in New York on May 16, 2007 (or such later date as agreed upon by the parties) (May 16, 2007 or such later date, if any, as agreed upon being the “Early Unwind Date”), this Transaction shall automatically terminate (the “Early Unwind”), on the Early Unwind Date and (i) the Transaction and all of the respective rights and obligations of Dealer and Company under the Transaction shall be cancelled and terminated and (ii) each party shall be released and discharged by the other party from and agrees not to make any claim against

10

the other party with respect to any obligations or liabilities of the other party arising out of and to be performed in connection with the Transaction either prior to or after the Early Unwind Date; provided that Company shall purchase from Dealer on the Early Unwind Date all Shares purchased by Dealer or one or more of its affiliates and shall, notwithstanding anything to the contrary in the Equity Definitions, reimburse Dealer for any costs or expenses (including market losses) relating to the unwinding of its hedging activities in connection with the Transaction (including any loss or cost incurred as a result of its terminating, liquidating, obtaining or reestablishing any hedge or related trading position). The amount of any such reimbursement shall be determined by Dealer in its sole good faith discretion. Dealer shall notify Company of such amount and Company shall pay such amount in immediately available funds on the Early Unwind Date. Dealer and Company represent and acknowledge to the other that, subject to the proviso included in this Section, upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged.

(i) Dividends. If at any time during the period from but excluding the Trade Date, to and including the Expiration Date, an ex-dividend date for a cash dividend occurs with respect to the Shares (an “Ex-Dividend Date”), and that dividend is greater than the Regular Dividend on a per Share basis, then the Calculation Agent will adjust any of the Strike Price, Number of Warrants and/or Daily Number of Warrants to preserve the fair value of the Options to Dealer after taking into account such dividend or lack thereof. “Regular Dividend” shall mean for any calendar quarter, USD 0.00 per Share.

(j) Role of Agent. Each party agrees and acknowledges that (i) X.X. Xxxxxx Securities Inc., an affiliate of JPMorgan (“JPMSI”), has acted solely as agent and not as principal with respect to this Transaction and (ii) JPMSI has no obligation or liability, by way of guaranty, endorsement or otherwise, in any manner in respect of this Transaction (including, if applicable, in respect of the settlement thereof). Each party agrees it will look solely to the other party (or any guarantor in respect thereof) for performance of such other party’s obligations under this Transaction.

(A) Company sells all or substantially all of its assets in a transaction pursuant to which the Shares are converted into cash, securities or other property.

(B) There is a default by Company or any subsidiary in the payment of the principal or interest on any mortgage, agreement or other instrument which results in the acceleration of maturity of any indebtedness for money borrowed in excess of $40 million in the aggregate of Company and/or any subsidiary, whether such indebtedness now exists or shall hereafter be created resulting in such indebtedness becoming or being declared due and payable, and such acceleration shall not have been rescinded or annulled within 10 days after written notice of such acceleration has been received by Company or such subsidiary.

(C) Any “person” or “group” within the meaning of Section 13(d) of the Exchange Act other than the Company, any of its subsidiaries or its employee benefit plans, files a Schedule TO or any schedule, form or report under the Exchange Act disclosing that such person or group has become the direct or indirect ultimate “beneficial owner”, as defined in Rule 13d-3 under the Exchange Act, of the common equity of the Company representing more than 50% of the voting power of such common equity.

(D) Dealer, despite using commercially reasonable efforts, is unable or reasonably determines that it is impractical or illegal, to hedge its obligations pursuant to this Transaction in the public market without registration under the Securities Act or as a result of any legal, regulatory or self-regulatory requirements or related policies and procedures (whether or not such requirements, policies or procedures are imposed by law or have been voluntarily adopted by Dealer).

(l) No Collateral or Setoff. Notwithstanding any provision of the Agreement or any other agreement between the parties to the contrary, the obligations of Company hereunder are not secured by any collateral. Obligations under this Transaction shall not be set off by Company against any other obligations of the parties, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise. Any provision in the Agreement with respect to the satisfaction of Company’s payment obligations to the extent of Dealer’s payment obligations to Company in the same currency and in the same Transaction (including, without limitation Section 2(c) thereof) shall not apply to Company and, for the avoidance of doubt, Company shall fully satisfy such payment obligations notwithstanding any

12

payment obligation to Company by Dealer in the same currency and in the same Transaction. In calculating any amounts under Section 6(e) of the Agreement, notwithstanding anything to the contrary in the Agreement, (1) separate amounts shall be calculated as set forth in such Section 6(e) with respect to (a) this Transaction and (b) all other Transactions, and (2) such separate amounts shall be payable pursuant to Section 6(d)(ii) of the Agreement.

(m) Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If, in respect of this Transaction, an amount is payable by Company to Dealer, (i) pursuant to Section 12.7 or Section 12.9 of the Equity Definitions (except in the event of an Insolvency, Nationalization, Tender Offer or Merger Event in which the consideration or proceeds to be paid to holders of shares consists solely of cash) or (ii) pursuant to Section 6(d)(ii) of the Agreement (except in the event of an Event of Default in which Company is the Defaulting Party or a Termination Event in which Company is the Affected Party, other than an Event of Default of the type described in (x) Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or (y) a Termination Event of the type described in Section 5(b) of the Agreement, in the case of both (x) and (y), resulting from an event or events outside Company’s control) (a “Payment Obligation”), Company shall have the right, in its sole discretion, to satisfy any such Payment Obligation by the Share Termination Alternative (as defined below) by giving irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 12:00 p.m. New York local time on the Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable; provided that if Company does not validly elect to satisfy its Payment Obligation by the Share Termination Alternative, Dealer shall have the right to require Company to satisfy its Payment Obligation by the Share Termination Alternative. Notwithstanding the foregoing, Company’s or Dealer’s right to elect satisfaction of a Payment Obligation in the Share Termination Alternative as set forth in this clause shall only apply to Transactions under this Confirmation and, notwithstanding anything to the contrary in the Agreement, (1) separate amounts shall be calculated with respect to (a) Transactions hereunder and (b) all other Transactions under the Agreement, and (2) such separate amounts shall be payable pursuant to Section 6(d)(ii) of the Agreement, subject to, in the case of clause (a), Company’s Share Termination Alternative right hereunder.

Share Termination Alternative:		If applicable, Company shall deliver to Dealer the Share Termination Delivery Property on the date (the “Share Termination Payment Date”) on which the Payment Obligation would otherwise be due pursuant to Section 12.7 or Section 12.9 of the Equity Definitions, subject to paragraph (n)(i) below, in satisfaction, subject to paragraph (n)(ii) below, of the Payment Obligation in the manner reasonably requested by Dealer free of payment.
Share Termination Delivery Property:		A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the amount of Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price.
Share Termination Unit Price:		The value to Dealer of property contained in one Share Termination Delivery Unit on the date such Share Termination Delivery Units are to be delivered as Share Termination Delivery Property, as determined by the Calculation Agent in its discretion

13

		by commercially reasonable means. The Calculation Agent shall notify Company of such Share Termination Unit Price at the time of notification of the Payment Obligation. In the case of a Private Placement of Share Termination Delivery Units that are Restricted Shares (as defined below), as set forth in paragraph (n)(i) below, the Share Termination Unit Price shall be determined by the discounted price applicable to such Share Termination Delivery Units. In the case of a Registration Settlement of Share Termination Delivery Units that are Restricted Shares (as defined below) as set forth in paragraph (n)(ii) below, the Share Termination Unit Price shall be the Settlement Price on the Merger Date, the Announcement Date (in the case of a Nationalization, Insolvency or Delisting) or the Early Termination Date, as applicable.
Share Termination Delivery Unit:		In the case of a Termination Event, Event of Default or Delisting, one Share or, in the case of Nationalization, Insolvency, Tender Offer or Merger Event, a unit consisting of the number or amount of each type of property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Nationalization, Insolvency, Tender Offer or Merger Event. If such Nationalization, Insolvency, Tender Offer or Merger Event involves a choice of consideration to be received by holders, such holder shall be deemed to have elected to receive the maximum possible amount of cash.
Failure to Deliver:		Inapplicable
Other applicable provisions:		If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9, 9.11, 9.12 and 10.5 (as modified above) of the Equity Definitions will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share Termination Settled” in relation to this Transaction means that Share Termination Alternative is applicable to this Transaction.

(n) Registration/Private Placement Procedures. If, in the reasonable opinion of Dealer, following any delivery of Shares or Share Termination Delivery Property to Dealer hereunder, such Shares or Share Termination Delivery Property would be in the hands of Dealer subject to any applicable restrictions with respect to any registration or qualification requirement or prospectus delivery requirement for such Shares or Share Termination Delivery Property pursuant to any applicable federal or state securities law (including, without limitation, any such requirement arising under Section 5 of the Securities Act as a result of such Shares or Share Termination Delivery Property being “restricted securities”, as such term is defined in Rule 144 under the Securities Act, or as a result of the sale of such Shares or Share Termination Delivery Property being subject to

14

paragraph (c) of Rule 145 under the Securities Act) (such Shares or Share Termination Delivery Property, “Restricted Shares”), then delivery of such Restricted Shares shall be effected pursuant to either clause (i) or (ii) below at the election of Company, unless Dealer waives the need for registration/private placement procedures set forth in (i) and (ii) below. Notwithstanding the foregoing, solely in respect of any Daily Number of Warrants exercised or deemed exercised on any Expiration Date, Company shall elect, prior to the first Settlement Date for the first Expiration Date, a Private Placement Settlement or Registration Settlement for all deliveries of Restricted Shares for all such Expiration Dates which election shall be applicable to all Settlement Dates for such Warrants and the procedures in clause (i) or clause (ii) below shall apply for all such delivered Restricted Shares on an aggregate basis commencing after the final Settlement Date for such Warrants. The Calculation Agent shall make reasonable adjustments to settlement terms and provisions under this Confirmation to reflect a single Private Placement or Registration Settlement for such aggregate Restricted Shares delivered hereunder.

(i) If Company elects to settle the Transaction pursuant to this clause (i) (a “Private Placement Settlement”), then delivery of Restricted Shares by Company shall be effected in customary private placement procedures with respect to such Restricted Shares reasonably acceptable to Dealer and Company; provided that Company may not elect a Private Placement Settlement if, on the date of its election, it has taken, or caused to be taken, any action that would make unavailable either the exemption pursuant to Section 4(2) of the Securities Act for the sale by Company to Dealer (or any affiliate designated by Dealer) of the Restricted Shares or the exemption permitting resales of the Restricted Shares by Dealer (or any such affiliate of Dealer). The Private Placement Settlement of such Restricted Shares shall include customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Dealer, due diligence rights (for Dealer or any designated buyer of the Restricted Shares by Dealer), opinions and certificates, and such other documentation as is customary for private placement agreements, all reasonably acceptable to Dealer. In the case of a Private Placement Settlement, Dealer shall determine the appropriate discount to the Share Termination Unit Price (in the case of settlement of Share Termination Delivery Units pursuant to paragraph (m) above) or any Settlement Price (in the case of settlement of Shares pursuant to Section 2 above) applicable to such Restricted Shares in a commercially reasonable manner and appropriately adjust the number of such Restricted Shares to be delivered to Dealer hereunder; provided that in no event shall such number be greater than 3,705,528 (the “Maximum Amount”). Notwithstanding the Agreement or this Confirmation, the date of delivery of such Restricted Shares shall be the Exchange Business Day following notice by Dealer to Company, of such applicable discount and the number of Restricted Shares to be delivered pursuant to this clause (i). For the avoidance of doubt, delivery of Restricted Shares shall be due as set forth in the previous sentence and not be due on the Share Termination Payment Date (in the case of settlement of Share Termination Delivery Units pursuant to paragraph (m) above) or on the Settlement Date for such Restricted Shares (in the case of settlement in Shares pursuant to Section 2 above).

In the event Company shall not have delivered the full number of Restricted Shares otherwise applicable as a result of the proviso above relating to the Maximum Amount (such deficit, the “Deficit Restricted Shares”), Company shall be continually obligated to deliver, from time to time until the full number of Deficit Restricted Shares have been delivered pursuant to this paragraph, Restricted Shares when, and to the extent, that (i) Shares are repurchased, acquired or otherwise received by Company or any of its subsidiaries after the Trade Date (whether or not in exchange for cash, fair value or any other consideration), (ii) authorized and unissued Shares reserved for issuance in respect of other transactions prior to such date which prior to the relevant date become no longer so reserved and (iii) Company additionally authorizes any unissued Shares that are not reserved for other transactions. Company shall immediately notify Dealer of the occurrence of any of the foregoing events (including the number of Shares subject to clause (i), (ii) or (iii) and the corresponding number of Restricted Shares to be delivered) and promptly deliver such Restricted Shares thereafter.

15

In the event of a Private Placement Settlement, the Net Share Settlement Amount or the Payment Obligation, respectively, shall be deemed to be the Net Share Settlement Amount or the Payment Obligation, respectively, plus an additional amount (determined from time to time by the Calculation Agent in its commercially reasonable judgment) attributable to interest that would be earned on such Net Share Settlement Amount or the Payment Obligation, respectively, (increased on a daily basis to reflect the accrual of such interest and reduced from time to time by the amount of net proceeds received by Dealer as provided herein) at a rate equal to the open Federal Funds Rate plus the Spread for the period from, and including, such Settlement Date or the date on which the Payment Obligation is due, respectively, to, but excluding, the related date on which all the Restricted Shares have been sold and calculated on an Actual/360 basis. The foregoing provision shall be without prejudice to Dealer’s rights under the Agreement (including, without limitation, Sections 5 and 6 thereof).

As used in this Section, “Spread” means, with respect to any Net Share Settlement Amount or Payment Obligation, respectively, the credit spread over the applicable overnight rate that would be imposed if Dealer were to extend credit to Company in an amount equal to such Net Share Settlement Amount, all as determined by the Calculation Agent using its commercially reasonable judgment as of the related Settlement Date or the date on which the Payment Obligation is due, respectively. Commercial reasonableness shall take into consideration all factors deemed relevant by the Calculation Agent, which are expected to include, among other things, the credit quality of Company (and any relevant affiliates) in the then-prevailing market and the credit spread of similar companies in the relevant industry and other companies having a substantially similar credit quality.

(ii) If Company elects to settle the Transaction pursuant to this clause (ii) (a “Registration Settlement”), then Company shall promptly (but in any event no later than the beginning of the Resale Period) file and use its reasonable best efforts to make effective under the Securities Act a registration statement or supplement or amend an outstanding registration statement in form and substance reasonably satisfactory to Dealer, to cover the resale of such Restricted Shares in accordance with reasonable customary resale registration procedures, including covenants, conditions, representations, underwriting discounts (if applicable), commissions (if applicable), indemnities, due diligence rights, opinions and certificates, and such other documentation as is reasonably customary for equity resale underwriting agreements, all reasonably acceptable to Dealer. If Dealer, in its sole reasonable discretion, is not satisfied with such procedures and documentation Private Placement Settlement shall apply. If Dealer is satisfied with such procedures and documentation, it shall sell the Restricted Shares pursuant to such registration statement during a period (the “Resale Period”) commencing on the Exchange Business Day following delivery of such Restricted Shares (which, for the avoidance of doubt, shall be (x) any Settlement Date in the case of an exercise of Warrants prior to the first Expiration Date pursuant to Section 2 above, (y) the Share Termination Payment Date in case of settlement in Share Termination Delivery Units pursuant to paragraph (m) above or (z) the Settlement Date in respect of the final Expiration Date for all Daily Number of Warrants) and ending on the earliest of (i) the Exchange Business Day on which Dealer completes the sale of all Restricted Shares or, in the case of settlement of Share Termination Delivery Units, a sufficient number of Restricted Shares so that the realized net proceeds of such sales equals or exceeds the Payment Obligation (as defined above), (ii) the date upon which all Restricted Shares have been sold or transferred pursuant to Rule 144 (or similar provisions then in force) or Rule 145(d)(1) or (2) (or any similar provision then in force) under the Securities Act and (iii) the date upon which all Restricted Shares may be sold or transferred by a non-affiliate pursuant to Rule 144(k) (or any similar provision then in force) or Rule 145(d)(3) (or any similar provision then

16

in force) under the Securities Act. If the Payment Obligation exceeds the realized net proceeds from such resale, Company shall transfer to Dealer by the open of the regular trading session on the Exchange on the Exchange Trading Day immediately following the last day of the Resale Period the amount of such excess (the “Additional Amount”) in cash or in a number of Shares (“Make-whole Shares”) in an amount that, based on the Settlement Price on the last day of the Resale Period (as if such day was the “Valuation Date” for purposes of computing such Settlement Price), has a dollar value equal to the Additional Amount. The Resale Period shall continue to enable the sale of the Make-whole Shares. If Company elects to pay the Additional Amount in Shares, the requirements and provisions for Registration Settlement shall apply. This provision shall be applied successively until the Additional Amount is equal to zero. In no event shall Company deliver a number of Restricted Shares greater than the Maximum Amount.

(iii) Without limiting the generality of the foregoing, Company agrees that any Restricted Shares delivered to Dealer, as purchaser of such Restricted Shares, (i) may be transferred by and among Dealer and its affiliates, if applicable, and Company shall effect such transfer without any further action by Dealer and (ii) after the minimum “holding period” within the meaning of Rule 144(d) under the Securities Act has elapsed after any Settlement Date for such Restricted Shares, Company shall promptly remove, or cause the transfer agent for such Restricted Shares to remove, any legends referring to any such restrictions or requirements from such Restricted Shares upon delivery by Dealer (or such affiliate of Dealer) to Company or such transfer agent of seller’s and broker’s representation letters customarily delivered by Dealer in connection with resales of restricted securities pursuant to Rule 144 under the Securities Act, without any further requirement for the delivery of any certificate, consent, agreement, opinion of counsel, notice or any other document, any transfer tax stamps or payment of any other amount or any other action by Dealer (or such affiliate of Dealer).

If the Private Placement Settlement or the Registration Settlement shall not be effected as set forth in clauses (i) or (ii), as applicable, then failure to effect such Private Placement Settlement or such Registration Settlement shall constitute an Event of Default with respect to which Company shall be the Defaulting Party.

(o) Limit on Beneficial Ownership. Notwithstanding any other provisions hereof, Dealer may not exercise any Warrant hereunder or be entitled to take delivery of any Shares deliverable hereunder, and Automatic Exercise shall not apply with respect to any Warrant hereunder, to the extent (but only to the extent) that, after such receipt of any Shares upon the exercise of such Warrant or otherwise hereunder, JPMorgan Chase & Co. would directly or indirectly beneficially own (as such term is defined for purposes of Section 13(d) of the Exchange Act) in excess of 8.0% of the outstanding Shares. Any purported delivery hereunder shall be void and have no effect to the extent (but only to the extent) that, after such delivery, JPMorgan Chase & Co. would directly or indirectly so beneficially own in excess of 8.0% of the outstanding Shares. If any delivery owed to Dealer hereunder is not made, in whole or in part, as a result of this provision, Company’s obligation to make such delivery shall not be extinguished and Company shall make such delivery as promptly as practicable after, but in no event later than one Business Day after, Dealer gives notice to Company that, after such delivery, JPMorgan Chase & Co. would not directly or indirectly so beneficially own in excess of 8.0% of the outstanding Shares.

(p) Share Deliveries. Company acknowledges and agrees that, to the extent the holder of this Warrant is not then an affiliate and has not been an affiliate for 90 days (it being understood that Dealer will not be considered an affiliate under this paragraph solely by reason of its receipt of Shares pursuant to this Transaction), and otherwise satisfies all holding period and other requirements of Rule 144 of the Securities Act applicable to it, any delivery of Shares or Share Termination Property hereunder at any time after 2 years from the Trade Date shall be eligible for resale under Rule 144(k) of the Securities Act and Company agrees to promptly remove, or cause the transfer agent for such Shares or Share Termination Property, to remove, any legends referring to any restrictions on resale under the Securities Act from the Shares or Share Termination Property.

17

Company further agrees, for any delivery of Shares or Share Termination Property hereunder at any time after 1 year from the Trade Date but within 2 years of the Trade Date, to the extent the holder of this Warrant then satisfies the holding period and other requirements of Rule 144 of the Securities Act, to promptly remove, or cause the transfer agent for such Restricted Share to remove, any legends referring to any such restrictions or requirements from such Restricted Share upon delivery by Dealer (or such affiliate of Dealer) to Company or such transfer agent of customary seller’s and broker’s representation letters in connection with resales of restricted securities pursuant to Rule 144 of the Securities Act, without any further requirement for the delivery of any certificate, consent, agreement, opinion of counsel, notice or any other document, any transfer tax stamps or payment of any other amount or any other action by Dealer (or such affiliate of Dealer). Company further agrees that any delivery of Shares or Share Termination Delivery Property prior to the date that is 1 year from the Trade Date, may be transferred by and among Dealer and its affiliates and Company shall effect such transfer without any further action by Dealer. Notwithstanding anything to the contrary herein, Company agrees that any delivery of Shares or Share Termination Delivery Property shall be effected, to the extent eligible, by book-entry transfer through the facilities of DTC, or any successor depositary, if at the time of delivery, such class of Shares or class of Share Termination Delivery Property is in book-entry form at DTC or such successor depositary. Notwithstanding anything to the contrary herein, to the extent the provisions of Rule 144 of the Securities Act or any successor rule are amended, or the applicable interpretation thereof by the Securities and Exchange Commission or any court change after the Trade Date, the agreements of Company herein shall be deemed modified to the extent necessary, in the opinion of outside counsel of Company, to comply with Rule 144 of the Securities Act, including Rule 144(k) as in effect at the time of delivery of the relevant Shares or Share Termination Property.

(q) Governing Law. New York law (without reference to choice of law doctrine).

(r) Waiver of Jury Trial. Each party waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any suit, action or proceeding relating to this Transaction. Each party (i) certifies that no representative, agent or attorney of the other party has represented, expressly or otherwise, that such other party would not, in the event of such a suit, action or proceeding, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other party have been induced to enter into this Transaction, as applicable, by, among other things, the mutual waivers and certifications provided herein.

(s) Tax Disclosure. Effective from the date of commencement of discussions concerning the Transaction, Company and each of its employees, representatives, or other agents may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the Transaction and all materials of any kind (including opinions or other tax analyses) that are provided to Company relating to such tax treatment and tax structure.

(t) Maximum Share Delivery. Notwithstanding any other provision of this Confirmation or the Agreement, in no event will Company be required to deliver more than the Maximum Amount of Shares in the aggregate to Dealer in connection with this Transaction, subject to the provisions regarding Deficit Restricted Shares. If, on any Valuation Date, the sum (for the Warrants and for all other similar warrants issued on the same date hereof) of (i) the aggregate Share Delivery Quantity with respect to each Valuation Date on or prior to such date and (ii) the product of (A) the Number of Warrants to be exercised on the immediately following Valuation Date and (B) the Warrant Entitlement exceeds the number of Shares that, if issued by Company without approval by its common stockholders, would violate certain listing standards of The New York Stock Exchange as set forth in the Indenture to be dated May 16, 2007 between Counterparty and The Bank of New York, as trustee, Company shall deliver the Net Share Settlement Amount in cash in lieu of delivering the Share Delivery Quantity with respect to each of the remaining Valuation Dates; provided that Company shall notify Dealer before 5:00 p.m. (New York City time) on such Valuation Date.

18

(u) Right to Extend. Dealer may postpone, in whole or in part, any Expiration Date or any other date of valuation or delivery with respect to some or all of the relevant Warrants (in which event the Calculation Agent shall make appropriate adjustments to the Daily Number of Warrants with respect to one or more Expiration Dates) if Dealer determines, in its commercially reasonable judgment, that such extension is reasonably necessary or appropriate to preserve Dealer’s hedging or hedge unwind activity hereunder in light of existing liquidity conditions or to enable Dealer to effect purchases of Shares in connection with its hedging, hedge unwind or settlement activity hereunder in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to Dealer.

(v) Status of Claims in Bankruptcy. Dealer acknowledges and agrees that this Confirmation is not intended to convey to Dealer rights against Company with respect to the Transaction that are senior to the claims of common stockholders of Company in any U.S. bankruptcy proceedings of Company; provided that nothing herein shall limit or shall be deemed to limit Dealer’s right to pursue remedies in the event of a breach by Company of its obligations and agreements with respect to the Transaction; provided, further, that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transactions other than the Transaction.

(w) Securities Contract; Swap Agreement. The parties hereto intend for: (a) the Transaction to be a “securities contract” and a “swap agreement” as defined in the Bankruptcy Code (Title 11 of the United States Code) (the “Bankruptcy Code”), and the parties hereto to be entitled to the protections afforded by, among other Sections, Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560 of the Bankruptcy Code; (b) a party’s right to liquidate the Transaction and to exercise any other remedies upon the occurrence of any Event of Default under the Agreement with respect to the other party to constitute a “contractual right” as described in the Bankruptcy Code; and (c) each payment and delivery of cash, securities or other property hereunder to constitute a “margin payment” or “settlement payment” and a “transfer” as defined in the Bankruptcy Code.

Re: Warrants

This letter agreement (the “Amendment”) amends the terms and conditions of the Transaction (the “Transaction”) entered into between JPMorgan Chase Bank, National Association, London Branch (“Dealer”) and CACI International Inc (“Company”), pursuant to a letter agreement dated May 10, 2007 (the “Confirmation”), pursuant to which Dealer has purchased from Company a Number of Warrants equal to 1,235,176. This Amendment relates to, and sets forth the terms of, the purchase by Dealer from Company of an additional Number of Warrants (the “Additional Number of Warrants”).

Upon the effectiveness of this Amendment, all references in the Confirmation to the “Number of Warrants” will be deemed to be to the Number of Warrants as amended hereby and all references in the Confirmation to the “Transaction” will be deemed to be to the Transaction as amended hereby. Except to the extent specified below, all other provisions of the Confirmation shall apply to the Additional Number of Warrants as if such Additional Number of Warrants were originally subject to the Confirmation.

1. The “Trade Date” with respect to the Additional Number of Warrants will be May 11, 2007.

3. The “Premium” for the Transaction will be $14,122,500 reflecting an increase of the premium payable by Dealer to Company in the amount of $1,412,250 for the Additional Number of Warrants.

4. Section 9(t) of the Confirmation is hereby amended by deleting the phrase “(for the Warrants and for all other similar warrants issued on the same date hereof)” and replacing it with the phrase “(for the Warrants and for all other similar warrants issued on May 10, 2007 and May 11, 2007).”

5. Each of Dealer and Company hereby repeats the representations, warranties and agreements made by such party in the Confirmation, with respect to the Amendment or with respect to the Confirmation, as amended by the Amendment, as the context requires.
