(ii) Members of, or participants in, the Depository (“Agent Members”) shall have no rights under this Agreement with respect to any Global Warrant held on their behalf by the Depository or by the Warrant Agent as the custodian of the Depository or under such Global Warrant, and the Depository may be treated by the Company, the Warrant Agent and any agent of the Company or the Warrant Agent as the absolute owner of such Global Warrant for all purposes whatsoever. Notwithstanding the foregoing, nothing in this Agreement shall prevent the Company, the Warrant Agent or any agent of the Company or the Warrant Agent from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practices of the Depository governing the exercise of the rights of a Holder of a beneficial interest in any Global Warrant.

Unless limited by the terms of such appointment, such agent may countersign Warrant Certificates whenever the Warrant Agent may do so.

Such agent will have the same rights as the Warrant Agent for service of notices and demands.

(d) At any time and from time to time after the execution of this Agreement, the Warrant Agent or an agent reasonably acceptable to the Company shall upon receipt of a written order of the Company signed by two (2) Officers of the Company manually countersign for original issue a Warrant Certificate evidencing the number of Warrants specified in such order; provided, however, that the Warrant Agent shall be entitled to receive an Officers’ Certificate that it may reasonably request in connection with such countersignature of Warrants. Such order shall specify the number of Warrants to be evidenced on the Warrant Certificate to be countersigned, the date on which such Warrant Certificate is to be countersigned and the number of Warrants then authorized.

(e) The Warrants evidenced by a Warrant Certificate shall not be valid until an authorized signatory of the Warrant Agent or its agent as provided above manually countersigns the Warrant Certificate. The signature shall be conclusive evidence that the Warrant Certificate has been countersigned under this Agreement.

Section 2.03. Certificate Register. The Warrant Agent shall keep a register (the “Certificate Register”) of the Warrant Certificates and of their transfer and exchange. The Certificate Register shall show the names and addresses of the respective Holders and the date and number of Warrants evidenced on the face of each of the Warrant Certificates.

At any time prior to such cancellation, if any beneficial interest in a

Global Warrant is exchanged for certificated Warrants, redeemed, repurchased or canceled, the number of Warrants represented by such Global Warrant shall be reduced and an adjustment shall be made on the books and records of the Warrant Agent (if it is then the Warrant Custodian for such Global Warrant) with respect to such Global Warrant, by the Warrant Agent, to reflect such reduction.

(d) Obligations with Respect to Transfers and Exchanges of Warrants.

owners in any Global Warrant) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Agreement, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Section 2.05. Certificated Warrants.

(a) A Global Warrant deposited with the Depository or with the Warrant Agent as custodian for the Depository pursuant to Section 2.01 shall be transferred to the beneficial owners thereof in the form of certificated Warrants in a number equal to the number of Warrants represented by such Global Warrant, in exchange for such Global Warrant, only if such transfer complies with Section 2.04 and (i) the Depository notifies the Company that it is unwilling or unable to continue as depositary for such Global Warrant or if at any time the Depository ceases to be a “clearing agency” registered under the Exchange Act and, in each such case, a successor depositary is not appointed by the Company within ninety (90) days of such notice or (ii) the Company, with the consent of the Required Warrant Holders, notifies the Warrant Agent in writing that it elects to cause the issuance of Certificated Warrants under this Agreement.

(b) Any Global Warrant that is transferable to the beneficial owners thereof pursuant to this Section 2.05 shall be surrendered by the Depository to the Warrant Agent, to be so transferred, in whole or from time to time in part, without charge, and the Warrant Agent shall countersign and deliver, upon such transfer of each portion of such Global Warrant, an equal number of Certificated Warrants. Any Certificated Warrants delivered in exchange for an interest in the Global Warrant shall bear the legends set forth in Section 2.04(b).

(c) Subject to the provisions of Section 2.05(b), the registered Holder of a Global Warrant may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Agreement or the Warrants.

(d) In the event of the occurrence of either of the events specified in Section 2.05(a), the Company will promptly make available to the Warrant Agent a reasonable supply of Certificated Warrants in definitive, fully registered form.

Section 2.06. Replacement Certificates. If a mutilated Warrant Certificate is surrendered to the Warrant Agent or if the Holder of a Warrant Certificate claims that the Warrant Certificate has been lost, destroyed or wrongfully taken, the Company shall issue and the Warrant Agent shall countersign a replacement Warrant Certificate if the reasonable requirements of the Warrant Agent and of Section 8-405 of the Uniform Commercial Code as in effect in the State of New York are met. If required by the Warrant Agent or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Warrant Agent to protect the Company and the Warrant Agent from any loss which either of them may suffer if a Warrant Certificate is replaced. The Company and the Warrant Agent may charge the Holder for their reasonable out-of-pocket expenses in replacing a Warrant Certificate. Every replacement Warrant Certificate evidences an additional obligation of the Company.

Section 2.07. Outstanding Warrants. Warrants outstanding at any time are all Warrants evidenced on all Warrant Certificates authenticated by the Warrant Agent except for those canceled by it and those delivered to it for cancellation. A Warrant does not cease to be outstanding because an Affiliate of the Company holds the Warrant. A Warrant ceases to be outstanding and shall no longer be exercisable if the Company or any Subsidiary of the Company holds the Warrant.

If a Warrant Certificate is replaced pursuant to Section 2.06 of this Agreement, the Warrants evidenced thereby cease to be outstanding and shall no longer be exercisable unless the Warrant Agent and the Company receive proof satisfactory to them that the replaced Warrant Certificate is held by a bona fide purchaser.

Section 2.08. Cancellation.

(a) In the event the Company or any Subsidiary of the Company shall purchase or otherwise acquire Certificated Warrants, the same shall thereupon be delivered to the Warrant Agent for cancellation.

(b) The Warrant Agent and no one else shall cancel and destroy all Warrant Certificates surrendered for transfer, exchange, replacement, exercise or cancellation and deliver a certificate of such destruction to the Company unless the Company directs the Warrant Agent to deliver canceled Warrant Certificates to the Company. The Company may not issue new Warrant Certificates to replace Warrant Certificates to the extent they evidence Warrants which have been exercised or Warrants which the Company or any Subsidiary of the Company has purchased or otherwise acquired.

Section 2.09. CUSIP Numbers. The Company in issuing the Warrants shall use “CUSIP” numbers and the Warrant Agent shall use “CUSIP” numbers in notices as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Warrant Certificates or as contained in any notice and that reliance may be placed only on the other identification numbers printed on the Warrant Certificates.

Section 2.10. Registration.

(a) Filing of Shelf Registration. The Company covenants and agrees that, within fifteen (15) Business Days of the execution of this Agreement (the “Required Filing Date”), it shall file one or more “shelf” registration statements pursuant to Rule 415 (or similar rule that may be adopted by the SEC) under the Securities Act (collectively, the “Shelf Registration Statement”) to permit on a continuous basis (i) resales of the Warrants by the Holders thereof who may be deemed Affiliates of the Company, (ii) the issuance of Warrant Shares upon the exercise of the Warrants by the Holders thereof, (iii) the resale of Warrant Shares by the Holders thereof who may be deemed Affiliates of the Company, (iv) resales of the Warrants issued to the Supporting Noteholders in connection with the Second Lien Term Loan and the resale of Warrant Shares issued to the Supporting Noteholders upon the exercise of such Warrants and (v) resales of the Warrants issued to ASOF in connection with the ASOF CTO Funding and the resale of Warrant Shares issued to ASOF upon the exercise of such Warrants

(the “Registrable Securities”). The Company shall use its reasonable best efforts to cause the Shelf Registration Statement to become effective as promptly as possible after the filing thereof, but in no event later than sixty (60) days after the Required Filing Date.

(b) The Shelf Registration Statement shall be on Form S-3. In the event Form S-3 is not available for the registration of the resale of Registrable Securities hereunder, the Company shall (i) register the resale of the Registrable Securities on Form S-1 or another appropriate form in accordance herewith as the Holders may consent and (ii) attempt to register the Registrable Securities on Form S-3 as soon as such form is available, provided, that, the Company shall maintain the effectiveness of the Shelf Registration Statements then in effect until such time as a Shelf Registration Statement on Form S-3 covering the Registrable Securities has been declared effective by the SEC.

(c) The Company shall use commercially reasonable best efforts to cause the Shelf Registration Statement to be declared effective by the SEC as promptly as reasonably possible after the filing thereof, but in any event within sixty (60) days of such filing (it being understood that the Company does not guarantee that the Registration Statement will be declared effective by the SEC within such time), and shall use commercially reasonable best efforts to keep the Shelf Registration Statement continuously effective under the Securities Act until such time as this Section 2.10 no longer survives following expiration of all of the Warrants pursuant to Section 3.04 hereof (the “Effectiveness Period”).

(d) The Company shall notify the Holders in writing as promptly as reasonably possible (and in any event within one (1) Business Day) after receiving notification from the SEC that the Shelf Registration Statement has been declared effective.

(e) Prior to the filing of the Shelf Registration Statement, any Prospectus or any amendments or supplements thereto, the Company shall furnish to the Holders’ Counsel copies of all such documents proposed to be filed, which documents will be subject to the review and reasonable approval of the Holders.

(f) The Company shall (i) prepare and file with the SEC such amendments, including post-effective amendments, to each Shelf Registration Statement and Prospectus as may be necessary to keep the Shelf Registration Statement continuously effective as to the applicable Registrable Securities for the Effectiveness Period (including as may be necessary to permit compliance with the requirements of Section 10(a)(3) of the Securities Act) and prepare and file with the SEC such additional Shelf Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities; (ii) cause the related Prospectus to be amended or supplemented by any required supplement, and as so supplemented or amended to be filed pursuant to Rule 424 under the Securities Act; (iii) respond as promptly as reasonably possible to any comments (other than non-substantive comments) received from the SEC with respect to the Shelf Registration Statement or any amendment thereto and provide the Holders’ Counsel with true and complete copies of all correspondence from and to the SEC relating to the Shelf Registration Statement as promptly as possible; provided, however, that the Company shall not provide copies of any correspondence that would result in the disclosure of material non-public information concerning the Company (it being understood that the Company shall provide such information to the Holders’ Counsel at such time as it is no longer material non-public

information); and (iv) comply in all material respects with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by the Shelf Registration Statement in accordance with the intended methods of disposition by the Holders set forth in the Shelf Registration Statement or Prospectus (in each case, as amended or supplemented).

(g) The Company shall notify the Warrant Agent and the Holders’ Counsel in the event that: (i) any Shelf Registration Statement or any post-effective amendment is declared effective; (ii) the SEC issues any stop order suspending the effectiveness of any Shelf Registration Statement or initiates any proceedings for that purpose; (iii) the Company receives notice of any suspension of the qualification or exemption from qualification of any Registrable Securities for sale in any jurisdiction, or the initiation or threat of any proceeding for such purpose; or (iv) the financial statements included or incorporated by reference in any Shelf Registration Statement become ineligible for inclusion or incorporation therein or any statement made in any Shelf Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference is untrue in any material respect or any revision to a Shelf Registration Statement, Prospectus or other document is required so that it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Company shall notify the Holders’ Counsel in the event that the SEC or any other federal or state Governmental Authority requests any amendment or supplement to any Shelf Registration Statement or Prospectus or requests additional information related thereto.

(h) Upon the occurrence of any event described in paragraph (g) above, the Company shall as promptly as reasonably possible, prepare a supplement or amendment, including a post-effective amendment, to the affected Shelf Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, neither the Shelf Registration Statement will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, nor such Prospectus will contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(i) The Company shall be permitted to suspend the availability of the Shelf Registration Statement and the use of any Prospectus only if the Company furnishes to the Holders a certificate signed by the chief executive or chief financial officer of the Company stating that in the good faith judgment of the Company’s Board of Directors: (A) any resale of Registrable Securities could reasonably be expected to materially interfere with an acquisition, corporate reorganization, financing or other material transaction then under consideration by the Company or (B) there is some other material development relating to the operations or condition (financial or other) of the Company that has not been disclosed to the general public and as to which it is in the Company’s best interests not to disclose; provided, however, that any period during which the availability of the Shelf Registration Statement and any Prospectus may be suspended pursuant to this clause (i) may not exceed forty-five (45) days in the aggregate during any twelve (12) month period; provided, further, that the Company may not so suspend the Shelf

Registration Statement or cause the Holders or any other holder of Registrable Securities to discontinue sales under the Shelf Registration Statement or Prospectus more than once in any calendar year.

(j) The Company shall use its commercially reasonable best efforts to avoid the issuance of or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of any Shelf Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, as soon as practicable.

(k) The Company shall promptly deliver to the Holders and each other holder of Registrable Securities, without charge, as many copies of the Prospectus and each amendment or supplement thereto as such Persons may reasonably request. The Company hereby consents to the use of such Prospectus and each amendment or supplement thereto by the Holders and each other holder of Registrable Securities in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto.

(l) The Company shall cooperate with the Holders and each other holder or transferee of Registrable Securities (i) to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to a Shelf Registration Statement, which certificates shall be free of all restrictive legends, and (ii) to enable such Registrable Securities to be in such denominations (permitted by any indenture governing such securities to the extent a debt security) and registered in such names as the Holders and each other holder or transferee of Registrable Securities may request.

(m) The Company shall pay all fees and expenses incident to the preparation and filing of the registration statements contemplated by this Section 2.10 by the Company, including (i) all registration and filing fees and expenses, including without limitation those related to filings with the SEC and in connection with applicable state securities or blue sky laws, (ii) printing expenses, (iii) messenger, telephone and delivery expenses, and (iv) reasonable and documented legal fees and expenses of the Holders’ Counsel (or reimburse the Holders for such fees and expenses of the Holders’ Counsel).

(n) Holder Information. Prior to filing the Shelf Registration Statement, the Company shall provide each Holder with a copy of the questionnaire in the form attached hereto as Annex A (the “Questionnaire”). In order to be named as a selling securityholder in the Prospectus at the time of effectiveness of the Shelf Registration Statement, each Holder must, before the effectiveness of the Shelf Registration Statement, have furnished a completed Questionnaire containing no material misstatement of fact and not omitting any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. From and after the date that the Shelf Registration Statement is first declared effective by the SEC, upon receipt of a completed Questionnaire from the Holders who had not prior to such time furnished a completed Questionnaire to the Company, the Company will use its reasonable best efforts to file within fifteen (15) Business Days thereafter any amendments or supplements to the Shelf Registration Statement necessary for such Holder to be named as a selling securityholder in the Shelf Registration Statement. Each Holder named as a selling securityholder in the Shelf Registration

Statement agrees to promptly furnish to the Company an updated Questionnaire in order to make information previously furnished to the Company by the Holder not materially misleading.

ARTICLE III

Exercise Terms

Section 3.01. Exercise.

(a) Each Warrant, when exercised, shall initially entitle the Holder thereof, subject to adjustment pursuant to the terms of this Agreement (including pursuant to Section 4.09), to purchase [·] shares of Common Stock. The exercise price of each Xxxxx Warrant is equal to $0.01 per share, subject to the adjustments provided for in this Agreement (the “Exercise Price”).

(b) Reserved.

(d) Reserved.

Section 3.02. Exercise Periods.

(a) Subject to the terms and conditions set forth in this Agreement, the Warrants shall be exercisable, in whole or in part, at any time and from time to time on or after the Closing Date.

(b) Reserved.

(d) Reserved.

(e) No Warrant shall be exercisable after [·], 2024 (the “Expiration Date”).

Section 3.03. Reserved.

Section 3.04. Expiration. A Warrant shall terminate and become void as of the earlier of (i) the close of business New York City time on the Expiration Date or (ii) the date such Warrant is exercised in full. The Company shall give notice not less than thirty (30), and not more than sixty (60), days prior to the Expiration Date to the Holders of all then outstanding Warrants to the effect that the Warrants will terminate and become void as of the close of business on the Expiration Date; provided, however, that if the Company fails to give notice as provided in this Section 3.04, the Warrants will nevertheless expire and become void on the Expiration Date.

Section 3.05. Manner of Exercise.

(a) Warrants may be exercised upon (i) delivery of the form of election to purchase Common Stock attached hereto as Exhibit C duly completed and signed by the Holder

and, with respect to certificated Warrants, the surrender to the Warrant Agent at the office of the Warrant Agent of the related Warrant Certificate and (ii) payment to the Warrant Agent, for the account of the Company, of the applicable Exercise Price for each Warrant Share issuable upon the exercise of such Warrants then exercised (a “Cash Exercise”). Such payment shall be made in cash or by certified or official bank check payable to the order of the Company or by wire transfer of funds to an account designated by the Company for such purpose.

(b) Warrants may also be exercised without the payment of cash, by reducing the number of shares of Common Stock obtainable upon the exercise of a Warrant so as to yield a number of shares of Common Stock upon the exercise of such Warrant equal to the product of (a) the number of shares of Common Stock issuable as of the Exercise Date upon the exercise of such Warrant (if payment of the applicable Exercise Price were being made in cash) and (b) the Cashless Exercise Ratio. An exercise of a Warrant in accordance with the immediately preceding sentence is herein called a “Cashless Exercise.” Upon surrender of a Warrant Certificate representing more than one Warrant in connection with the Holder’s option to elect a Cashless Exercise, the number of shares of Common Stock deliverable upon a Cashless Exercise shall be equal to the number of shares of Common Stock issuable upon the exercise of Warrants that the Holder specifies are to be exercised pursuant to a Cashless Exercise multiplied by the Cashless Exercise Ratio. All provisions of this Agreement shall be applicable with respect to a surrender of a Warrant Certificate pursuant to a Cashless Exercise for less than the full number of Warrants represented thereby.

(c) Subject to Section 3.02, the rights represented by the Warrants shall be exercisable at the election of the Holders thereof either in full at any time or from time to time in part and in the event that a Warrant Certificate is surrendered for exercise of less than all the Warrants represented by such Warrant Certificate at any time prior to the Expiration Date, a new Warrant Certificate representing the remaining Warrants shall be issued. In the case of certificated Warrants, the Warrant Agent shall countersign and deliver to the Holders the required new Warrant Certificates, and the Company, at the Warrant Agent’s request, shall supply the Warrant Agent with Warrant Certificates duly signed on behalf of the Company for such purpose.

Section 3.06. Issuance of Shares of Common Stock. Subject to Section 2.06, upon the exercise of Warrants in accordance with the terms of this Agreement, the Company shall issue and cause a transfer agent for the Common Stock (the “Stock Transfer Agent”) to countersign and deliver to or upon the written order of the Holder and in such name or names as the Holder may designate, a certificate or certificates for the number of full shares of Common Stock so purchased upon the exercise of such Warrants or other securities or property to which it is entitled, registered or otherwise, to the Person or Persons entitled to receive the same (including any depositary institution so designated by a Holder), together with cash as provided in Section 3.07 in respect of any fractional shares of Common Stock otherwise issuable upon such exercise; provided, however, that if, at such date, the transfer books for the shares of Common Stock shall be closed, the certificates for the Common Stock in respect of which such Warrants are then exercised shall be issuable as of the date on which such books shall next be opened and until such date the Company shall be under no duty to deliver any certificates for such Common Stock; provided further, however, that such transfer books, unless otherwise required by law, shall not be closed at any one time for a period longer than twenty (20) calendar days. Such certificate or certificates

shall be deemed to have been issued and any Person so designated to be named therein shall be deemed to have become a holder of record of such shares of Common Stock as of the date of the exercise of Warrants pursuant to the terms of this Agreement. Upon the exercise of any Warrant and the receipt by a Holder of the shares of Common Stock as a result thereof, the Holder will be deemed to be bound by, and covenants to thereupon execute a joinder to, the Stockholders’ Agreement in accordance with the terms thereof.

Section 3.07. Fractional Shares of Common Stock. The Company shall not be required to issue fractional shares of Common Stock on the exercise of Warrants. If more than one (1) Warrant shall be exercised in full at the same time by the same Holder, the number of full shares of Common Stock which shall be issuable upon such exercise shall be computed on the basis of the aggregate number of shares of Common Stock which may be purchasable pursuant thereto. If any fraction of a shares of Common Stock would, except for the provisions of this Section 3.07, be issuable upon the exercise of any Warrant (or specified portion thereof), the Company shall be entitled to pay an amount in cash equal to the Current Market Value per share of Common Stock, as determined on the day immediately preceding the date the Warrant is presented for exercise, multiplied by such fraction, computed to the nearest whole cent.

Section 3.08. Reservation of Shares of Common Stock.

(a) The Company shall at all times keep reserved out of its authorized shares of Common Stock a number of shares of Common Stock sufficient to provide for the exercise of all outstanding Warrants. The registrar for the Common Stock (the “Registrar”) shall at all times until the Expiration Date reserve such number of authorized shares as shall be required for such purpose. The Company will keep a copy of this Agreement on file with the Stock Transfer Agent. The Company will supply such Stock Transfer Agent with duly executed stock certificates for such purpose and will itself provide or otherwise make available any cash which may be payable as provided in Section 3.07. The Company will furnish to such Stock Transfer Agent a copy of all notices of adjustments (and certificates related thereto) transmitted to each Holder.

(b) Reserved.

(c) The Company covenants that all shares of Common Stock which may be issued upon exercise of and payment for Warrants in accordance with the provisions of this Agreement shall, upon issue, be fully paid, nonassessable, free from all stamp and documentary taxes and free from all liens, charges and security interests with respect to the issue thereof.

Section 3.09. Compliance with Law. Notwithstanding anything in this Agreement to the contrary, in no event shall a Holder be entitled to exercise a Warrant unless (i) a registration statement filed under the Securities Act in respect of the issuance of the Warrant Shares is then effective or (ii) in the opinion of counsel to the Company addressed to the Warrant Agent the exercise of such Warrants is exempt from the registration requirements of the Securities Act and such securities are qualified for sale or exempt from qualification under the applicable securities laws of the states or other jurisdictions in which such Holders reside.

Section 3.10. Reserved.

Section 3.11. Right of First Offer. In the event of a ROFO Sale (as such term is defined in the Stockholders’ Agreement) Holders shall have the rights and be subject to all of the obligations set forth in Section 2.2 of the Stockholders’ Agreement, which section is incorporated herein by reference mutatis mutandis.

Section 3.12. Reserved.

Section 3.13. Preemptive Rights.

(a) In the event that the Company proposes to sell or otherwise issue New Securities that vote with the Common Stock for the election of directors generally and the Holders would not be entitled to (i) receive such New Securities as a dividend or distribution or (ii) receive an adjustment in the number of Warrant Shares issuable upon exercise of such Holders’ Warrants as provided in ARTICLE IV (a “Preemptive Rights Issuance”), each Holder holding Warrants representing five percent (5%) of the aggregate Warrant Shares to be received upon the exercise of all then outstanding Warrants (a “Significant Holder”) shall have the right to acquire up to that number or amount of such New Securities, at the price and upon substantially the same terms and conditions as such New Securities are to be sold or otherwise issued by the Company, as shall enable such Significant Holder to maintain the percentage of voting power for the election of directors generally with the Common Stock such Significant Holder would hold in the Company upon exercise of such Significant Holder’s Warrants prior to such sale or other issuance of New Securities (assuming the exercise, exchange or conversion of all Convertible Securities in accordance with their terms). In the event that the Company proposes to sell or otherwise issue New Securities that generally do not vote with the Common Stock for the election of directors generally, each Significant Holder shall have the right to acquire up to that number or amount of such New Securities, at the price and upon substantially the same terms and conditions as such New Securities are to be sold or otherwise issued by the Company, equal to the product of (i) the number or amount of such New Securities being sold or otherwise issued times (ii) the percentage of voting power for the election of directors generally with the Common Stock of such Significant Holder immediately prior to such sale or other issuance of such New Securities (assuming the exercise, exchange or conversion of all Convertible Securities in accordance with their terms). For purposes of this Section 3.13, “New Securities” means any Common Equivalent Shares, including any such securities issued by the Company in connection with the ESOP.

(b) In the event that the Company proposes to undertake a Preemptive Rights Issuance, the Company shall give each Significant Holder and the Warrant Agent written notice (the “Preemptive Rights Notice”) of its intention, stating (i) the type of New Securities, (ii) the purchase price, number and general terms upon which the Company proposes to issue or sell such New Securities and (iii) the estimated or actual closing date, as applicable, of the sale or issuance of New Securities. The Preemptive Rights Notice shall be given to (x) in the case of sales or issuances of New Securities other than in connection with Participant Elective Deferrals, each Significant Holder and the Warrant Agent at least twenty (20) Business Days prior to the first closing of the proposed sale or issuance or (y) in the case of issuances of New Securities in connection with Participant Elective Deferrals, the Warrant Agent within ten (10) Business Days

following the first issuance of such New Securities. Each Significant Holder shall have the right, for a period of thirty (30) Business Days after receipt of the Preemptive Rights Notice (the “Preemptive Rights Acceptance Period”), to agree to purchase up to its pro rata share of such New Securities. Such acceptance shall be made by delivering a written notice to the Company, the Warrant Agent and the ESOP Trustee within the Preemptive Rights Acceptance Period specifying the number of New Securities that such Significant Holder shall purchase. For purposes of this Section 3.13, the “pro rata share” of a Significant Holder shall mean the number or amount of New Securities which shall enable such Significant Holder to maintain, assuming the conversion of all Convertible Securities in accordance with their terms, the percentage equity interest such Significant Holder would hold in the Company upon exercise of such Significant Holder’s Warrants immediately prior to such sale or other issuance of New Securities at the purchase price and on the terms stated in the Preemptive Rights Notice. The Company shall include in any filings with the SEC on Form 8-K regarding a Preemptive Rights Issuance in connection with Participant Elective Deferrals a disclosure that such sale or issuance is subject to the provisions of this Section 3.13 and that Significant Holders have the rights set forth herein.

(c) In the event the Company delivers the Preemptive Rights Notice in accordance with Section 3.13(b), the Company shall have a period of sixty (60) Business Days (the “New Securities Sale Period”) from the date of the first closing specified in the Preemptive Rights Notice to sell to third parties all such New Securities not purchased by Holders pursuant to this Section 3.13 at a price and upon general terms no more favorable to the purchasers thereof than the price and terms specified in the Preemptive Rights Notice. In the event the Company has not sold all such New Securities within the New Securities Sale Period, then the Company shall not thereafter make any Preemptive Rights Issuance without first offering the New Securities to be sold or issued pursuant to such Preemptive Rights Issuance to the Significant Holders in accordance with this Section 3.13.

(d) If the purchase price in connection with any Preemptive Rights Issuance includes consideration other than cash, then the Significant Holders exercising their preemptive rights pursuant to this Section 3.13 shall pay to the Company, in lieu of paying such non-cash consideration, an amount in cash equal to the fair market value of such non-cash consideration as of the date such non-cash consideration would have been delivered in exchange for such New Securities, as determined by an independent nationally recognized investment bank with experience in transactions of comparable size and magnitude (an “Independent Financial Expert”) selected by the Company and acceptable the Requisite Holders (as defined in the Stockholders’ Agreement).

(e) The closing of any Preemptive Rights Issuance shall take place at such time and place as specified in the Preemptive Rights Notice. At the closing of Preemptive Rights Issuance, the Company shall issue and deliver to each Significant Holder stock certificates (or, if applicable, executed agreements) representing that number of fully paid and nonassessable New Securities that each Significant Holder has purchased pursuant to this Section 3.13 (duly endorsed, or with stock (or equivalent) powers duly endorsed, for transfer with signature guaranteed, free and clear of any liens or encumbrances, with any stock (or equivalent) transfer tax stamps affixed), or other appropriate transfer instruments, if the New Securities are uncertificated, and each such Significant Holder shall pay to the Company by wire transfer of immediately available funds the aggregate consideration for such New Securities.

Notwithstanding the foregoing or anything in this Section 3.13 to the contrary, to the extent the New Securities are not being sold pursuant to a registration statement under the Securities Act, the Company shall not be required to sell any New Securities to a Significant Holder unless an exemption from the registration requirements of the Securities Act is available without additional expense to the Company.

Section 3.14. Purchase of Warrants by Company; No Redemption. Subject to complying with all restrictions contained in any other agreement to which they are parties (including the Revolving Credit Facility, the First Lien Term Loan, the Second Lien Term Loan or the Third Lien Notes Indenture), the Company and its Subsidiaries may purchase in the open market, by private contracts or otherwise, all or any portion of the Warrants on such terms as the Company may obtain. Notwithstanding anything to the contrary in this Agreement, the Company shall have no right to redeem the Warrants.

Section 3.15. Restrictions on Transfer. Notwithstanding anything to the contrary in this Agreement, including Section 3.11, absent the written consent of the Board, no Holder shall Transfer any Warrants to any Person:

(i) If such Transfer would (A) violate any applicable securities or other laws, (B) unless the Common Stock is registered pursuant to Section 12(b) or 12(g) of the Exchange Act, result in the Company having, if such Warrant were exercised, stockholders of record exceeding in number either (1) 2,000 or (2) 500 or more persons who are not Accredited Investors, or (C) limit, impair or eliminate the Company’s net operating losses either upon Transfer or upon the exercise of such Warrant;

(ii) If the transferee is determined by the Board, in its good faith judgment, to be a competitor, customer or supplier of the Company or any Subsidiary of the Company and such transfer would be adverse to the Company and its Subsidiaries taken as a whole; or

(iii) if such Transfer would have adverse regulatory consequences on the Company or any Subsidiary, including (A) subjecting the Company to review or investigation conducted by the Committee on Foreign Investment in the United States, (B) creating a situation where the Company or any Subsidiary of the Company would operate, or would be deemed to operate, under foreign ownership, control or influence as determined within the meaning of the National Industrial Security Program Operating Manual, (C) creating an actual or potential organizational conflict of interest that cannot be mitigated, or (D) subjecting the Company or any Subsidiary to suspension or debarment from receiving contracts with the United States.

ARTICLE IV

Antidilution Provisions

Section 4.01. Cash Dividends and Distributions. In the event that at any time and from time to time the Company shall distribute to all holders of Common Stock any dividend or other distribution (including any dividend or distribution made in connection with a consolidation or

merger in which the Company is the continuing corporation or any repurchase, redemption or other acquisition of Common Stock by the Company or any subsidiary of the Company) in cash, then the Company shall pay and distribute such dividends and distributions to the Holders of any outstanding Warrants on the record date for such dividends or other distributions as if such Warrants had been exercised immediately prior to such record date.

Section 4.02. Other Dividends and Distributions. In the event that at any time and from time to time the Company shall distribute to all holders of Common Stock any dividend or other distribution of (including any dividend or distribution made in connection with a consolidation or merger in which the Company is the continuing corporation) or otherwise issue to all holders of Common Stock (i) evidences of its indebtedness, shares of its Capital Stock or any other properties or securities or (ii) any options, warrants or other rights to subscribe for or purchase any of the foregoing (other then in the case of clauses (i) and (ii) above, (A) any dividend or distribution described in Section 4.03 or (B) any rights, options, warrants or securities described in Section 4.04 or Section 4.05), then the number of Warrant Shares issuable upon the exercise of each Warrant immediately prior to such record date for any such dividend or distribution shall, automatically and without the requirement of further action by the Company or any Holder, be increased to a number determined by multiplying the number of Warrant Shares issuable upon the exercise of such Warrant immediately prior to such record date for any such dividend or distribution by a fraction, the numerator of which shall be the Current Market Value per share of Common Stock on the record date for such dividend or distribution (less any cash paid to Holders pursuant to Section 4.01 as part of the same transaction), and the denominator of which shall be such Current Market Value per share of Common Stock less the then fair value of the portion, if any, of the distribution applicable to one share of Common Stock consisting of evidences of indebtedness, securities, other property, warrants, options or subscription or purchase rights. Such adjustments shall be made, and shall only become effective, whenever any dividend or distribution is made; provided, however, that the Company is not required to make an adjustment pursuant to this Section 4.02 if at the time of such distribution the Company makes the same distribution to Holders as it makes to holders of Common Stock pro rata based on the number of shares of Common Stock for which such Warrants are exercisable (whether or not currently exercisable). Notwithstanding anything to the contrary in this Section 4.02, no adjustment shall be made pursuant to this Section 4.02 which shall have the effect of decreasing the number of Warrant Shares issuable upon exercise of each Warrant or increasing the Exercise Price.

Section 4.03. Changes in Common Stock. In the event that at any time and from time to time the Company shall (i) pay a dividend or make a distribution on the Common Stock with shares of Common Stock or other shares of Capital Stock, (ii) subdivide its outstanding shares of Common Stock into a larger number of shares of Common Stock, (iii) combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock or (iv) increase or decrease the number of shares of Common Stock outstanding by reclassification of its Common Stock, then the number of shares of Common Stock issuable upon exercise of each Warrant immediately after the happening of such event and the Exercise Price shall be adjusted so that, after giving effect to such adjustment, the Holder of each Warrant shall be entitled to receive the number of shares of Common Stock or other shares of Capital Stock upon exercise of such Warrant that such Holder would have owned or would have been entitled to receive had such Warrants been exercised (whether or not currently exercisable) immediately prior to the happening of the events described above (or, in the case of a dividend or distribution on the

Common Stock, immediately prior to the record date therefor). An adjustment made pursuant to this Section 4.03 shall become effective immediately after the distribution date, retroactive to the record date therefor in the case of a dividend or distribution in shares of Common Stock or other shares of Capital Stock, and shall become effective immediately after the effective date in the case of a subdivision, combination or reclassification.

Section 4.04. Common Stock Issue. In the event that at any time or from time to time the Company shall issue shares of Common Stock, the number of shares of Common Stock issuable upon the exercise of each Warrant immediately after such issuance date shall be determined by multiplying the number of shares of Common Stock issuable upon exercise of each Warrant immediately prior to such issuance date by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately preceding the issuance of such shares plus the number of additional shares of Common Stock to be issued in such transaction, and the denominator of which shall be the number of shares of Common Stock outstanding immediately preceding the date for the issuance of such shares. Adjustments shall be made, and shall only become effective, whenever shares are issued. No adjustment shall be made pursuant to this Section 4.04 (i) which shall have the effect of decreasing the number of Warrant Shares issuable upon exercise of each Warrant or increasing the applicable Exercise Price or (ii) on account of the Company’s issuance of any Common Stock (a) in accordance with terms of a Qualified Incentive Plan or (b) upon the exercise of any rights, options or warrants issued in accordance with terms of a Qualified Incentive Plan.

Section 4.05. Issuance of Rights, Options, Warrants or Common Stock. In the event that at any time or from time to time the Company shall issue (i) rights, options or warrants to acquire (provided, however, that no adjustment shall be made under Section 4.04 or this Section 4.05 upon the exercise of such rights, options or warrants), or (ii) securities convertible, exchangeable or exercisable into (provided, however, that no adjustment shall be made under Section 4.04 or this Section 4.05 upon the conversion, exchange or exercise of such securities (other than issuances specified in clauses (i) or (ii) which are made as the result of anti-dilution adjustments in such securities)), Common Stock, the number of shares of Common Stock issuable upon the exercise of each Warrant immediately after such issuance shall be determined by multiplying the number of shares of Common Stock issuable upon exercise of each Warrant immediately prior to such issuance by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to the issuance of such rights, options, warrants or securities plus the number of additional shares of Common Stock offered for subscription or purchase or into which such securities are convertible or exchangeable, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to the issuance of such rights, options, warrants or securities. Such adjustment shall be made, and shall only become effective, whenever such rights, options, warrants or securities are issued. No adjustment shall be made pursuant to this Section 4.05 (i) which shall have the effect of decreasing the number of Warrant Shares issuable upon exercise of each Warrant or increasing the Exercise Price or (ii) on account of the Company’s issuance of any rights, options or warrants in accordance with the terms of a Qualified Incentive Plan.

Section 4.06. Voluntary Increases. The Company may, but shall not be obligated to, make increases in the number of Warrant Shares, in addition to those required by Section 4.01 through Section 4.05 of this ARTICLE IV, as it considers to be advisable in order that any event

treated for United States federal income tax purposes as a dividend of stock or stock rights shall not be taxable to the recipients, or if that is not possible, to diminish any income taxes that are otherwise payable because of such event; provided that no such adjustment shall be made without the consent of the Required Warrant Holders if such adjustment would result in the increase of income tax liabilities of the Holders.

Section 4.07. Combination; Liquidation.

(a) Except as provided in Section 4.07(b), in the event that at any time a Liquidity Event occurs, then, to the extent any Warrants will remain outstanding immediately following such Liquidity Event, as a condition of the consummation of the Liquidity Event, lawful and adequate provision shall be made so that each Holder, upon the exercise thereof at any time on or after the consummation of the Liquidity Event, shall be entitled to receive, and such Warrant shall thereafter represent the right to receive, in lieu of the Common Stock or securities, cash or other property issuable upon exercise of the Warrant prior to such consummation, the securities, cash or other property to which such Holder would have been entitled upon consummation of the Liquidity Event if such Holder had exercised such Warrant immediately prior thereto (whether or not currently exercisable and subject to adjustments from and after the consummation date as nearly equivalent as possible to the adjustments provided for in this ARTICLE IV). Subject to paragraph (b) of this Section 4.07, the Company will not effect any Liquidity Event unless prior to the consummation thereof each corporation or entity (other than the Company) which may be required to deliver any securities or other property upon the exercise of the Warrants as provided in this Agreement shall assume, by written instrument delivered to each Holder of the Warrants, the obligation to deliver to such Holder such securities or other property as in accordance with the foregoing provisions such Holder may be entitled to receive, and such corporation or entity shall have similarly mailed or delivered to each Holder of the Warrants an opinion of counsel for such corporation or entity, reasonably satisfactory to the Required Warrant Holders, which opinion shall state that all of the outstanding Warrants, including the provisions of this ARTICLE IV, shall thereafter continue in full force and effect and shall be enforceable against the Company and such corporation or entity in accordance with the terms hereof and thereof, together with such other matters as such Holders may reasonably request. The foregoing provisions of this Section 4.07 shall similarly apply to successive mergers, consolidations, sales of assets, liquidations and recapitalizations.

(b) In the event of (i) a Liquidity Event where consideration to all holders of the Common Stock (or any other security into which the Warrants are then exercisable) in exchange for their securities is payable solely in cash or (ii) the dissolution, liquidation or winding-up of the Company, the Holders shall be entitled to receive, upon surrender of their Warrants, only such cash distributions (or, in the case of in-kind distributions upon dissolution, liquidation or winding-up of the Company, such other consideration as is being so distributed) on an equal basis with the holders of Common Stock (or any other security into which the Warrants are then exercisable) in exchange for their securities, as if the Warrants had been exercised immediately prior to such event (whether or not currently exercisable), less the Exercise Price.

(c) In the event of any Liquidity Event described Section 4.07(b), the surviving or acquiring Person and, in the event of any dissolution, liquidation or winding-up of the Company, the Company, shall deposit promptly with the Warrant Agent the funds, if any,

necessary to pay the Holders the amounts to which they are entitled as described above. After such funds and the surrendered Warrants are received, the Warrant Agent shall make payment to the Holders by delivering a check or wire transfer in such amount as is appropriate (or, in the case of consideration other than cash, such other consideration as is appropriate) to such Person or Persons as it may be directed in writing by the Holders surrendering such Warrants.

Section 4.08. 2010 Warrants. If at any time or from time to time on or before March 15, 2017 a Liquidity Event occurs, then the number of shares of Common Stock issuable upon the exercise of each Warrant immediately prior to such event shall, automatically and without the requirement of further action by the Company or any Holder, be increased to a number determined by multiplying the number of shares of Common Stock issuable upon exercise of each Warrant immediately prior to such event by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately preceding such event plus the number of additional shares of Common Stock that would have been issuable upon exercise of the 2010 Warrants pursuant to antidilution adjustments under Article IV of the 2010 Warrant Agreement (the “Additional 2010 Warrant Shares”) if all of the Warrants (whether or not the Warrants are then exercisable) were exercised immediately prior to such Liquidity Event and the denominator of which shall be the number of shares of Common Stock outstanding immediately preceding such Liquidity Event plus the number of shares of Common Stock which the aggregate exercise price for the Additional 2010 Warrant Shares would purchase at the price per share of Common Stock to be paid to the Company’s stockholders or to be received by the Company in connection with such Liquidity Event. No adjustments shall be made pursuant to this Section 4.08 which shall have the effect of decreasing the number of Warrant Share issuable upon exercise of each Warrant.

Section 4.09. Prior Period ESOP Issuance. In the event of a Prior Period ESOP Issuance, the number of shares of Common Stock issuable upon exercise of the Warrants shall, automatically and without the requirement of further action by the Company or any Holder, be increased by a number determined as follows, which adjustment shall be treated as an adjustment to the purchase price to be paid in acquiring property for U.S. federal income tax purposes:

(a) the number of shares issuable upon exercise of each Warrant shall be increased by an amount equal to:

	(Aggregate number of shares of Common Stock issued or purchased
	in such Prior Period ESOP Issuance / 0.6) x 0.4
	[·](1)

(b) Reserved.

(1) Will be the aggregate number of Xxxxx Warrants issued on the date of this Agreement

(d) Reserved.

Section 4.10. Superseding Adjustment. Upon the expiration of any rights, options, warrants or conversion or exchange privileges which resulted in adjustments pursuant to this ARTICLE IV, if any thereof shall not have been exercised, the number of Warrant Shares issuable upon the exercise of each Warrant shall be readjusted pursuant to the applicable section of ARTICLE IV as if (i) the only Warrant Shares issuable upon exercise of such rights, options, warrants, conversion or exchange privileges were the Warrant Shares, if any, actually issued upon the exercise of such rights, options, warrants or conversion or exchange privileges and (ii) Warrant Shares actually issued, if any, were issuable for the consideration actually received by the Company upon such exercise plus the aggregate consideration, if any, actually received by the Company for the issuance, sale or grant of all such rights, options, warrants or conversion or exchange privileges whether or not exercised and the Exercise Price shall be readjusted inversely; provided, however, that no such readjustment (except by reason of an intervening adjustment under any other provision of this ARTICLE IV) shall have the effect of decreasing the number of Warrant Shares issuable upon the exercise of each Warrant or increasing the Exercise Price by an amount in excess of the amount of the adjustment initially made in respect of the issuance, sale or grant of such rights, options, warrants or conversion or exchange privileges.

Section 4.11. Minimum Adjustment. The adjustments required by the preceding sections of this ARTICLE IV shall be made whenever and as often as any specified event requiring an adjustment shall occur, except that no adjustment of the applicable Exercise Price or the number of Warrant Shares issuable upon exercise of the Warrants that would otherwise be required shall be made unless and until such adjustment either by itself or with other adjustments not previously made increases or decreases by at least one percent (1%) of the applicable Exercise Price or the number of Warrant Shares issuable upon exercise of the Warrants immediately prior to the making of such adjustment. Any adjustment representing a change of less than such minimum amount shall be carried forward and made as soon as such adjustment, together with other adjustments required by this ARTICLE IV and not previously made, would result in a minimum adjustment. For the purpose of any adjustment, any specified event shall be deemed to have occurred at the close of business on the date of its occurrence. In computing adjustments under this Article IV, fractional interests in Common Stock shall be taken into account to the nearest one-ten millionth (1/10,000,000th) of a share.

Section 4.12. Notice of Adjustment. Whenever the Exercise Price or the number of Warrant Shares issuable upon exercise of the Warrants is adjusted, as herein provided, the Company shall deliver to the Warrant Agent a certificate of the Company’s chief executive officer or chief financial officer setting forth, in reasonable detail, the event requiring the adjustment and the method by which such adjustment was calculated (including a description of the basis and all supporting documentation on which (i) the Board determined the then fair value of any evidences of indebtedness, other securities or property or warrants, options or other subscription or purchase rights and (ii) the Current Market Value of the Common Stock was determined, if either of such determinations were required), and specifying the Exercise Price and the number and type of shares of Common Stock issuable upon exercise of the Warrants after giving effect to such adjustment. The Company shall promptly cause the Warrant Agent to deliver such certificate to each Holder in accordance with Section 5.02(g). The Warrant Agent shall be entitled to rely on such certificate and shall be under no duty or responsibility with respect to any such certificate,

except to exhibit the same from time to time, to any Holder desiring an inspection thereof during reasonable business hours. The Warrant Agent shall not at any time be under any duty or responsibility to any Holder to determine whether any facts exist which may require any adjustment of the Exercise Price or the number of Warrant Shares issuable on exercise of the Warrants, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed in making such adjustment or the validity or value of any Warrant Shares.

Section 4.13. Notice of Certain Transactions. In the event that the Company shall propose to (a) pay any dividend payable in securities of any class to the holders of its Common Stock or to make any other non-cash dividend or distribution to the holders of its Common Stock, (b) offer the holders of its Common Stock rights to subscribe for or to purchase any securities convertible into shares of Common Stock or shares of stock of any class or any other securities, rights or options, (c) issue any (i) shares of Common Stock, (ii) rights, options or warrants entitling the holders thereof to subscribe for shares of Common Stock or (iii) securities convertible into or exchangeable or exercisable for Common Stock (in the case of (i), (ii) and (iii), if such issuance or adjustment would result in an adjustment hereunder), (d) effect any capital reorganization, reclassification, consolidation or merger, (e) effect the voluntary or involuntary dissolution, liquidation or winding-up of the Company or (f) make a tender offer or exchange offer with respect to the Common Stock, the Company shall within five (5) Business Days after any such action or offer send to the Warrant Agent a notice of such proposed action or offer and the Warrant Agent shall send the Holders a notice thereof in accordance with Section 5.02(g) (in such form as shall be furnished to the Warrant Agent by the Company). Such notice shall specify the record date for the purposes of such dividend, distribution or rights, or the date such issuance or event is to take place and the date of participation therein by the holders of Common Stock, if any such date is to be fixed, and shall briefly indicate the effect, if any, of such action on the Common Stock and on the number and kind of any other shares of stock and on other property, if any, and the number of shares of Common Stock and other property, if any, issuable upon exercise of each Warrant and the Exercise Price after giving effect to any adjustment pursuant to ARTICLE IV which will be required as a result of such action. Such notice shall be given as promptly as possible and (x) in the case of any action covered by clause (a) or (b) above, at least ten (10) days prior to the record date for determining holders of the Common Stock for purposes of such action or (y) in the case of any other such action, at least twenty (20) days prior to the date of the taking of such proposed action or the date of participation therein by the holders of Common Stock, whichever shall be the earlier.

Section 4.14. Adjustment to Warrant Certificate. The form of Warrant Certificate need not be changed because of any adjustment made pursuant to this ARTICLE IV, and Warrant Certificates issued after such adjustment may state the same applicable Exercise Price and the same number of shares of Common Stock issuable upon exercise of the Warrants as are stated in the Warrant Certificates initially issued pursuant to this Agreement. The Company, however, may at any time in its sole discretion make any change in the form of Warrant Certificate that it may deem appropriate to give effect to such adjustments and that does not affect the substance of the Warrant Certificate, and any Warrant Certificate thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant Certificate or otherwise, may be in the form as so changed.

Section 4.15. No Dilution or Impairment; Reference to Common Stock.

(a) The Company will not, by amendment of its certificate of incorporation or through reorganization, consolidation, merger, dissolution, issue or sale of securities, sale of assets or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Agreement, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate in order to protect the rights of the Holders against dilution or other impairment. Without limiting the generality of the foregoing, the Company will take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable shares of Common Stock upon the exercise of a Warrant pursuant to this Agreement.

(b) If as a result of any adjustment made pursuant to this ARTICLE IV a Holder may receive upon exercise of a Warrant shares of one (1) or more classes or series of Capital Stock of the Company (other than the Common Stock), the number of shares of each such class or series of Capital Stock issuable upon the exercise of a Warrant, and the Exercise Price with respect to each such class or series of Capital Stock, shall prior to the exercise of a Warrant be subject to further adjustment on terms comparable to those applicable to the Common Stock in this ARTICLE IV and references to Common Stock in ARTICLE IV shall include each such class or series of Capital Stock.

(e) Not Responsible for Adjustments or Validity of Stock.

The Warrant Agent shall not be accountable with respect to the validity or value of any shares of Common Stock or of any securities or property which may at any time be issued or delivered upon the exercise of any Warrant or upon any adjustment pursuant to ARTICLE IV, and it makes no representation with respect thereto. The Warrant Agent shall not be responsible for any failure of the Company to make any cash payment or to issue, transfer or deliver any shares of Common Stock or stock certificates upon the surrender of any Warrant Certificate for the purpose of exercise or upon any adjustment pursuant to ARTICLE IV, or to comply with any of the covenants of the Company contained in ARTICLE IV.

(f) Reserved.

The Warrant Agent shall, at the Company’s expense, deliver all demands, notices, requests, consents and other communications and information delivered to it (collectively, “Notices”), in its capacity as Warrant Agent, by the Company, any Holder or any holder of Common Stock pursuant to the terms of the Stockholders’ Agreement or this Agreement, to the Holders or any subset thereof (as provided in the Stockholders’ Agreement or this Agreement, as applicable) promptly following receipt of such Notices, but in no event later than two (2) Business Days following such receipt for Warrants held of record by the Depository (which notice shall be delivered electronically) or five (5) Business Days following such receipt for Warrants held of record by Persons other than the Depositary (which notice shall be delivered by mail).

The Company need not reimburse any expense or indemnify against any loss or liability incurred by the Warrant Agent through willful misconduct, gross negligence or bad faith. The Company’s payment obligations pursuant to this Section 5.05 shall survive the termination of this Agreement.

To secure the Company’s payment obligations under this Agreement, the Warrant Agent shall have a lien prior to the Holders on all money or property held or collected by the Warrant Agent.

Section 5.06. Successor Warrant Agent.

(a) The Company To Provide and Maintain Warrant Agent. The Company agrees for the benefit of the Holders that there shall at all times be a Warrant Agent hereunder until all the Warrants have been exercised or cancelled or are no longer exercisable. Any Warrant Agent to qualify as the Warrant Agent hereunder must be able to qualify as the trustee under the indenture relating to the Third Lien Notes.

(b) Resignation and Removal. The Warrant Agent may at any time resign by giving written notice to the Company and the Holders (in accordance with Section 5.02(g)) of such intention on its part, specifying the date on which its desired resignation shall become effective, provided, however, that such date shall not be less than sixty (60) days after the date on which such notice is given unless the Company otherwise agrees. The Warrant Agent hereunder may be removed at any time by the filing with it of an instrument in writing signed by or on behalf of the Required Warrant Holders and specifying such removal and the date when it shall become effective, which date shall not be less than sixty (60) days after such notice is given

unless the Warrant Agent otherwise agrees. Any removal under this Section 5.06 shall take effect upon the appointment by the Company as hereinafter provided of a successor Warrant Agent (which shall be a bank or trust company authorized under the laws of the jurisdiction of its organization to exercise corporate trust powers) and the acceptance of such appointment by such successor Warrant Agent.

In the event that at any time the Warrant Agent shall resign, or shall be removed, or shall become incapable of acting, or shall be adjudged bankrupt or insolvent, or shall commence a voluntary case under the Federal bankruptcy laws, as now or hereafter constituted, or under any other applicable U.S. Federal or state bankruptcy, insolvency or similar law or shall consent to the appointment of or taking possession by a receiver, custodian, liquidator, assignee, trustee, sequestrator (or other similar official) of the Warrant Agent or its property or affairs, or shall make an assignment for the benefit of creditors, or shall admit in writing its inability to pay its debts generally as they become due, or shall take corporate action in furtherance of any such action, or a decree or order for relief by a court having jurisdiction in the premises shall have been entered in respect of the Warrant Agent in an involuntary case under the Federal bankruptcy laws, as now or hereafter constituted, or any other applicable Federal or state bankruptcy, insolvency or similar law, or a decree or order by a court having jurisdiction in the premises shall have been entered for the appointment of a receiver, custodian, liquidator, assignee, trustee, sequestrator (or similar official) of the Warrant Agent or of its property or affairs, or any public officer shall take charge or control of the Warrant Agent or of its property or affairs for the purpose of rehabilitation, conservation, winding up or liquidation, a successor Warrant Agent, qualified as aforesaid, acceptable to the Required Warrant Holders shall be appointed by the Company by an instrument in writing, filed with the successor Warrant Agent. Upon the appointment as aforesaid of a successor Warrant Agent and acceptance by the successor Warrant Agent of such appointment, the Warrant Agent shall cease to be Warrant Agent hereunder; provided, however, that in the event of the resignation of the Warrant Agent under this subsection (c), such resignation shall be effective on the earlier of (i) the date specified in the Warrant Agent’s notice of resignation and (ii) the appointment and acceptance of a successor Warrant Agent hereunder.

(d) Successor To Expressly Assume Duties. Any successor Warrant Agent appointed hereunder shall execute, acknowledge and deliver to its predecessor and to the Company an instrument accepting such appointment hereunder, and thereupon such successor Warrant Agent, without any further act, deed or conveyance, shall become vested with all the rights and obligations of such predecessor with like effect as if originally named as Warrant Agent hereunder, and such predecessor, upon payment of its charges and disbursements then unpaid, shall thereupon become obligated to transfer, deliver and pay over, and such successor Warrant Agent shall be entitled to receive, all monies, securities and other property on deposit with or held by such predecessor, as Warrant Agent hereunder.

(e) Successor by Merger.

(a) Reserved.

(b) Reserved.

(d) Except as otherwise provided in this Agreement, Holders are not entitled to exercise any rights whatsoever as stockholders of the Company.

(e) No Holders nor any of their respective Affiliates (collectively, the “Identified Persons” and, individually, an “Identified Person”), shall, to the fullest extent permitted by law, have any duty to refrain from directly or indirectly (i) engaging in the same or similar business activities or lines of business in which the Company or any Subsidiary is engaged or proposes to engage or (ii) otherwise competing with the Company or any Subsidiary, and, to the fullest extent permitted by law, no Identified Person shall be liable to the Company or its equity holders or to any Subsidiary of the Company for breach of any fiduciary duty solely by reason of the fact that such Identified Person engages in any such activities.

(f) The Company does not renounce its interest in any Relevant Corporate Opportunity presented to any Identified Person if such Relevant Corporate Opportunity is expressly presented to such person solely in his or her capacity as a member of the Board of the Company, and the provisions of Section 6.03(e) shall not apply to any such Relevant Corporate Opportunity.

Section 6.04. Amendment.

WARRANTS TO PURCHASE COMMON STOCK OF
ALION SCIENCE AND TECHNOLOGY CORPORATION

THIS CERTIFIES THAT [ ], or its registered assigns, is the registered holder of the number of Warrants set forth above (the “Warrants”). Each Warrant entitles the holder thereof (the “Holder”), at its option and subject to the provisions contained herein and in the Warrant Agreement referred to below, to purchase from ALION SCIENCE AND TECHNOLOGY CORPORATION, a Delaware corporation (the “Company”), [ ] shares of Common Stock, par value of $0.01 per share, of the Company (the “Common Stock”) at an exercise price of $0.01 per share (the “Exercise Price”), or by Cashless Exercise referred to below. This Warrant Certificate shall terminate and become void as of the close of business on [ ], 2024 (the “Expiration Date”) or upon the exercise hereof as to all the shares of Common Stock subject hereto. The number of shares issuable upon exercise of the Warrants shall be subject to adjustment from time to time as set forth in the Warrant Agreement.

This Warrant Certificate is issued under and in accordance with a Warrant Agreement dated as of [ ], 2014 (the “Warrant Agreement”), between the Company and Wilmington Trust, National Association (in such capacity, the “Warrant Agent”, which term includes any successor Warrant Agent under the Warrant Agreement), and is subject to the terms and provisions contained in the Warrant Agreement, to all of which terms and provisions the Holder of this Warrant Certificate consents by acceptance hereof. The Warrant Agreement is hereby incorporated herein by reference and made a part hereof. Reference is hereby made to the Warrant Agreement for a full statement of the respective rights, limitations of rights, duties and obligations of the Company, the Warrant Agent and the Holders. Capitalized terms used but not defined herein shall have the meanings ascribed thereto in the Warrant Agreement. A copy of the Warrant Agreement may be obtained for inspection by the Holder hereof upon written request to the Warrant Agent at 0000 Xxxxx Xxxxxx Xxxxxx, Xxxxxxxxxx, XX 00000-0000, Attention: Corporate Capital Markets.

Subject to the terms of the Warrant Agreement, the Warrants may be exercised in whole or in part (i) by presentation of this Warrant Certificate with the Election to Purchase attached hereto duly executed and with the simultaneous payment of the Exercise Price in cash (subject to adjustment) to the Warrant Agent for the account of the Company at the office of the Warrant Agent or (ii) by Cashless Exercise. Payment of the Exercise Price in cash shall be made by certified or official bank check payable to the order of the Company or by wire transfer of funds to an account designated by the Company for such purpose. Payment by Cashless Exercise shall be made without the payment of cash by reducing the amount of Common Stock that would be obtainable upon the exercise of a Warrant and payment of the Exercise Price in cash so as to yield a number of shares of Common Stock upon the exercise of such Warrant equal to the product of (1) the number of shares of Common Stock for which such Warrant is exercisable as of the Exercise Date (if the Exercise Price were being paid in cash) and (2) a fraction, the numerator of which is the excess of the Current Market Value per share of Common Stock on the

A-2

Exercise Date over the Exercise Price per share as of the Exercise Date and the denominator of which is the Current Market Value per share of the Common Stock on the Exercise Date.

As provided in the Warrant Agreement and subject to the terms and conditions therein set forth, the Warrants shall be exercisable at the time specified in the Warrant Agreement; provided, however, that Holders will be able to exercise their Warrants only if (i) the exercise is pursuant to an effective registration statement under the Securities Act or (ii) in the opinion of counsel to the Company addressed to the Warrant Agent the exercise of such Warrants is exempt from the registration requirements of the Securities Act of 1933 and such securities are qualified for sale or exempt from qualification under the applicable securities laws of the states or other jurisdictions in which such Holders reside; provided further, however, that no Warrant shall be exercisable after Expiration Date.

In the event of a Liquidity Event, the Holder hereof will be entitled to receive upon exercise of the Warrants the kind and amount of shares of Capital Stock or other securities, cash or other property as the Holder would have received had the Holder exercised its Warrants immediately prior to such Liquidity Event; provided, however, that in the event that, in connection with such Liquidity Event, consideration to holders of Common Stock in exchange for their shares is payable solely in cash or in the event of the dissolution, liquidation or winding-up of the Company, the Holder hereof will be entitled to receive such cash distributions on an equal basis with the holders of Common Stock or other securities issuable upon exercise of the Warrants, as if the Warrants had been exercised immediately prior to such Liquidity Event, less the Exercise Price.

As provided in the Warrant Agreement, the number of shares of Common Stock issuable upon the exercise of the Warrants is subject to adjustment upon the happening of certain events.

If a Holder proposes to transfer its Warrants to an unaffiliated third party, such Holder must first offer to Persons beneficially owning more than five percent (5%) of the Common Stock the option to purchase such Warrants on the same terms and conditions as provided in the proposed sale to such third party. The right of first offer will remain open for a period of twenty two (22) days, following which the Company will have the option to acquire any remaining Warrants not purchased by such Holders.

Except in the case of a sale or issuance for which the Holders are entitled to receive an adjustment pursuant to Article IV of the Warrant Agreement, the Significant Holders shall have a preemptive right to purchase their pro rata share of all New Securities offered for sale by the Company at a price and upon substantially the same terms as such New Securities are to be sold or issued by the Company.

The Company may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges in connection with the registration of the transfer or exchange of the Warrant Certificates pursuant to Section 2.04 of the Warrant Agreement, but not for any exchange or original issuance (not involving a transfer) with respect to temporary Warrant Certificates, the exercise of the Warrants or the Common Stock.

A-3

Upon any partial exercise of the Warrants in certificated form, there shall be countersigned and issued to the Holder hereof a new Warrant Certificate representing those Warrants which were not exercised. This Warrant Certificate may be exchanged at the office of the Warrant Agent by presenting this Warrant Certificate properly endorsed with a request to exchange this Warrant Certificate for other Warrant Certificates evidencing an equal number of Warrants. No fractional shares of Common Stock will be issued upon the exercise of the Warrants, but the Company shall pay an amount in cash equal to the Current Market Value per share of Common Stock on the day immediately preceding the date the Warrant is exercised, multiplied by the fraction of such share of Common Stock that would be issuable on the exercise of any Warrant, computed to the nearest whole cent.

All shares of Common Stock issuable by the Company upon the exercise of the Warrants and payment therefor shall, upon such issue, be duly and validly issued and fully paid and non-assessable.

The Holder in whose name the Warrant Certificate is registered may be deemed and treated by the Company and the Warrant Agent as the absolute owner of the Warrant Certificate for all purposes whatsoever and neither the Company nor the Warrant Agent shall be affected by notice to the contrary.

This Warrant Certificate shall not be valid or obligatory for any purpose until it shall have been countersigned by the Warrant Agent.
