The Notes will be issued pursuant to an indenture (the "Indenture"), to be dated as of May 19, 2010, by and among the Company, the Guarantors party thereto and Wilmington Trust FB, as trustee (the "Trustee"). Capitalized terms used, but not defined herein, shall have the meanings set forth in the "Description of the Notes" section of the Final Offering Memorandum (as hereinafter defined).

The Notes will be offered and sold to the Initial Purchasers pursuant to an exemption from the registration requirements of the Securities Act of 1933, as amended, and the rules and regulations of the Securities and Exchange Commission (the "SEC") thereunder (collectively, the "Securities Act"). Upon original issuance thereof, and until such time as the same is no longer required under the applicable requirements of the Securities Act, the Notes shall bear the legends set forth in the final offering memorandum, dated the date hereof (the "Final Offering Memorandum"). The Company has prepared a preliminary offering memorandum, dated May 3, 2010 (the "Preliminary Offering Memorandum"), (ii) a pricing term sheet, dated the date hereof, attached hereto as Schedule II, which includes pricing terms and other information with respect to the Notes (the "Pricing Supplement"), and (iii) the Final Offering Memorandum, in each case, relating to the offer and sale of the Notes (the "Offering").

There exists no condition that, with the passage of time or otherwise, would constitute (a) a violation of such Charter Documents or Applicable Laws, (b) a breach of or default or a "Debt Repayment Triggering Event" (as defined below) under any Applicable Agreement or (c) result in the imposition of any penalty or the acceleration of any indebtedness. As used herein, a "Debt Repayment Triggering Event" means any event or condition that gives, or with the giving of notice or lapse of time would give, the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder's behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company, any of its Subsidiaries, any Gichner Entity or any of their respective properties.

(u): No Conflicts. Neither the execution, delivery or performance of the Documents nor the consummation of any of the Transactions will conflict with, violate, constitute a breach of or a default (with the passage of time or otherwise) or a Debt Repayment Triggering Event under, or result in the imposition of a Lien on any assets of the Company, any of its Subsidiaries and, upon consummation of the Acquisition, any Gichner Entity (except for Permitted Liens or Liens pursuant to the Collateral Agreements), the imposition of any penalty or a Debt Repayment Triggering Event under or pursuant to (i) the Charter Documents, (ii) any Applicable Agreement, (iii) any Applicable Law or (iv) any order, writ, judgment, injunction, decree, determination or award binding upon or affecting the Company, its Subsidiaries or, upon consummation of the Acquisition, any Gichner Entity. After consummation of the Offering and the Transactions, no Default or Event of Default will exist.
(v): No Consents. No consent, approval, authorization, order, filing or registration of or with any Governmental Authority or third party is required for execution, delivery or performance of the Documents or the consummation of the Transactions, except such (i) those that have been official or made, as the case may be, that are in full force and effect, (ii) as may be required under the securities or "Blue Sky" laws of U.S. state or non-U.S. jurisdictions or other non-U.S. laws applicable to the purchase of the Securities outside the U.S. in connection with the Transactions, (iii) those contemplated by the Registration Rights Agreement and the Collateral Agreements; and (iv) or the filing of a Current Report on Form 8-K with the SEC as may be required under the Securities Act and the Exchange Act, as the case may be, regarding the Documents and the Transactions.
(w): No Material Applicable Laws or Proceedings. Except as disclosed in the Time of Sale Document and the Final Offering Memorandum, there is no action, claim, suit, demand, hearing, notice of violation or deficiency, or proceeding pending or, to the knowledge of the Company or any of its Subsidiaries, after due inquiry, threatened or contemplated by Governmental Authorities or threatened by others (collectively, "Proceedings") that, would, as of the date hereof and at the Closing Date, restrain, enjoin, prevent or interfere with the consummation of the Offering or any of the Transactions or (B) would, individually or in the aggregate, have a Material Adverse Effect.

(x): All Necessary Permits. Each of the Company, its Subsidiaries and each Gichner Entity possesses all licenses, permits, certificates, consents, orders, approvals and other authorizations from, and has made all declarations and filings with, all Governmental Authorities, presently required or necessary to own or lease, as the case may be, and to operate its properties and to carry on its businesses as now or proposed to be conducted as described in the Time of Sale Document and the Final Offering Memorandum ("Permits"), except where the failure to possess such Permits would not, individually or in the aggregate, have a Material Adverse Effect; each of the Company, its Subsidiaries and each Gichner Entity has fulfilled and performed all of its obligations with respect to such Permits; no event has occurred which allows, or after notice or lapse of time would allow, revocation or termination of any such Permit or has resulted, or after notice or lapse of time would result, in any other material impairment of the rights of the holder of any such Permit; and none of the Company, any of its Subsidiaries or any Gichner Entity has received or has any reason to believe it will receive any notice of any proceeding relating to revocation or modification of any such Permit, except as described in the Time of Sale Document and the Final Offering Memorandum or except where such revocation or modification would not, individually or in the aggregate, have a Material Adverse Effect.
(y): Title to Properties. The Company and Subsidiaries do not own any real property. Each of the Company, its Subsidiaries and Gichner has good title to all personal property owned by it and good and valid title to all leasehold estates in real and personal property being leased by it and, as of the Closing Date, will be free and clear of all Liens other than Permitted Liens. All Applicable Agreements to which the Company or any of its Subsidiaries is a party or by which any of them is bound are valid and enforceable against each of the Company or such Subsidiary, as applicable, and are valid and enforceable against the other party or parties thereto and are in full force and effect with only such exceptions as would not, individually or in the aggregate, have a Material Adverse Effect.
(z): Tax Law Compliance. All Tax (as hereinafter defined) returns required to be filed by the Company, each of its Subsidiaries and each Gichner Entity have been filed and all such returns are true, complete and correct in all material respects. All material Taxes that are due from the Company, its Subsidiaries and Gichner have been paid other than those (i) currently payable without penalty or interest or (ii) being contested in good faith and by appropriate proceedings and for which adequate accruals have been established in accordance with generally accepted accounting principles of the United States, applied on a consistent basis throughout the periods involved ("GAAP"). To the knowledge of the Company, after due inquiry, there are no actual or proposed Tax assessments against the Company, any of its Subsidiaries or any Gichner Entity that would, individually or in the aggregate, have a Material Adverse Effect. The accruals on the books and records of the Company, its Subsidiaries and Gichner in respect of any material Tax liability for any period not finally determined are adequate to meet any assessments of Tax for any such period. For purposes of this Agreement, the term "Tax" and "Taxes" shall mean all U.S. and non-U.S. federal, state, local and taxes, and other assessments of a similar nature (whether imposed directly or through withholding), including any interest, additions to tax or penalties applicable thereto.

None of the Company, its Subsidiaries or any Gichner Entity is a party to, or bound by, any options, licenses or agreements with respect to the intellectual property rights of any other person

or entity that are necessary to be described in the Time of Sale Document or the Final Offering Memorandum to avoid a material misstatement or omission and are not described therein. No claims or notices of any potential claim have been asserted by any person challenging the use of any such Intellectual Property by the Company, any of its Subsidiaries or any Gichner Entity or questioning the validity or effectiveness of any Intellectual Property or any license or agreement related thereto, other than any claims that, if successful, would not, individually or in the aggregate, have a Material Adverse Effect. None of the intellectual property used by the Company, any of its Subsidiaries or any Gichner Entity has been obtained or is hereby used by the Company, any of its Subsidiaries or any Gichner Entity in violation of any contractual obligation binding on the Company, any of its Subsidiaries or any Gichner Entity or, to the Company or any of its Subsidiaries' knowledge, their respective officers, directors or employees or otherwise in violation of the rights of any person.

(dd): Compliance with Environmental Laws. Except as disclosed in the Time of Sale Document and the Final Offering Memorandum, each of the Company, its Subsidiaries and Gichner is (i) in compliance with any and all applicable U.S. or non-U.S. federal, state and local laws and regulations relating to health and safety, or the pollution or the protection of the environment or hazardous or toxic substances of wastes, pollutants or contaminants ("Environmental Laws"), (ii) has received and is in compliance with all permits, licenses or other approvals required of them under applicable Environmental Laws to conduct its respective businesses and (iii) has not received notice of, and is not aware of, any actual or potential liability for damages to natural resources or the investigation or remediation of any disposal, release or existence of hazardous or toxic substances or wastes, pollutants or contaminants, in each case except where such non-compliance with Environmental Laws, failure to receive and comply with required permits, licenses or other approvals, or liability would not, individually or in the aggregate, have a Material Adverse Effect. Except as disclosed in the Time of Sale Document and the Final Offering Memorandum, none of the Company, any of its Subsidiaries or any Gichner Entity has been named as a "potentially responsible party" under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended, or any similar U.S. or non-U.S. state or local Environmental Laws or regulation requiring the Company, any of its Subsidiaries or any Gichner Entity to investigate or remediate any pollutants or contaminants, except where such requirements would not, individually or in the aggregate, have a Material Adverse Effect, whether or not arising from transactions in the ordinary course of business. In the ordinary course of its business, the Company and Gichner periodically reviews the effects of Environmental Laws on the business, operations and properties of the Company and its Subsidiaries and Gichner, respectively, in the course of which it identifies and evaluates associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws, or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties). On the basis of such review, the Company and, to the Company's knowledge, Gichner have reasonably concluded that such associated costs would not have a Material Adverse Effect.
(ee): Insurance. Each of the Company, its Subsidiaries and each Gichner Entity is insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which it is engaged. All policies of insurance insuring the Company, any of its Subsidiaries or any Gichner Entity or their respective businesses, assets, employees, officers and directors are in full force and effect. The Company, its Subsidiaries and Gichner are in compliance with the terms of such policies and instruments in all material respects, and there are no claims by the Company, any of its Subsidiaries or any Gichner Entity under any such policy or instrument as to which any insurance company is denying liability or defending under a reservation of rights clause. None of the Company, any of its Subsidiaries or any Gichner Entity has been refused any insurance coverage sought or applied for, and none of the Company, any of its Subsidiaries or any Gichner Entity has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not, individually or in the aggregate, have a Material Adverse Effect.
(ff): Accounting System.

material differences. The Company's management concluded that the Company's internal control over financial reporting was effective as of December 27, 2009, and since that date the independent auditors and board of directors of the Company have been advised of: (i) all "material weaknesses" and "significant deficiencies" (each, as defined in Rule 12b-2 of the Exchange Act), if any, in the design or operation of the Company's internal control over financial reporting which are reasonably likely to adversely affect the Company's ability to record, process, summarize and report financial information and (ii) any fraud, whether or not material, that involves management or other employees who have a role in the Company's internal control over financial reporting (whether or not remediated). Except as disclosed in the Time of Sale Document and the Final Offering Memorandum, as of the date hereof there are no material weaknesses in the Company's internal control over financial reporting. Since the date of the most recent evaluation of the Company's disclosure controls and procedures and internal control over financial reporting, there have been no changes in the Company's internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

The relative benefits received by the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, shall be deemed to be in the same proportion as the total proceeds from the Offering (before deducting expenses) received by the Company bear to the total discounts and commissions received by the Initial Purchasers. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or the Initial Purchasers pursuant to Section 8(b) above, on the other hand, the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or alleged statement or omissions, and any other equitable considerations appropriate in the circumstances.

(f): Equitable Consideration. The Company, the Guarantors and the Initial Purchasers agree that it would not be equitable if the amount of such contribution determined pursuant to Section 8(e) were determined by pro rata or per capita allocation or by any other method of allocation that does not take into account the equitable considerations referred to in Section 8(e). Notwithstanding any other provision of this Section, the Initial Purchasers shall not be obligated to make contributions hereunder that in the aggregate exceed the total discounts, commissions and other compensation received by such Initial Purchasers under this Agreement, less the aggregate amount of any damages that such Initial Purchasers have otherwise been required to pay by reason of the untrue or alleged untrue statements or the omissions or alleged omissions to state a material fact. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers' obligation to contribute hereunder shall be several in proportion to their respective purchase obligations hereunder and not joint. For purposes of Section 8(e), each director, officer and employee of each Initial Purchaser, and each person, if any, who controls the Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Initial Purchasers, and each director, officer and employee of the Company and the Guarantors, and each person, if any, who controls the Company or any of the Guarantors within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company and the Guarantors.

9. Termination. Jefferies may terminate this Agreement at any time prior to the Closing Date by written notice to the Company if any of the events described in Sections 7(h) (No Material Adverse Change), 7(i) (No Hostilities) or 7(j) (No Suspension in Trading; Banking Moratorium) shall have occurred or if the Initial Purchasers shall decline to purchase the Securities for any reason permitted by this Agreement. Any termination pursuant to this Section shall be without liability on the part of (a) the Company or the Guarantors to the Initial Purchasers, except that the Company and the Guarantors shall be obligated to reimburse the expenses of the Initial Purchasers pursuant to Section 5(f) hereof or (b) the Initial Purchasers to the Company or the Guarantors, except, in the case of each of clauses (a) and (b), that the provisions of Sections 9 and 10 hereof shall at all times be effective and shall survive such termination.

10. Survival. The representations and warranties, covenants, indemnities and contribution and expense reimbursement provisions and other agreements of the Company and the Guarantors set forth in or made pursuant to this Agreement shall remain operative and in full force and effect, and will survive, regardless of (i) any investigation, or statement as to the results thereof, made by or on behalf of the Initial Purchasers, (ii) the acceptance of the Securities, and payment for them hereunder, and (iii) any termination of this Agreement.

11. Defaulting Initial Purchaser. If, on the Closing Date, any one of the Initial Purchasers shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities which such defaulting Initial Purchaser agreed but failed or refused to purchase is not more than one tenth of the aggregate principal amount of Securities to be purchased on such date, the other Initial Purchasers shall be obligated severally in the proportions that the principal amount of Securities set forth opposite their respective names in Schedule I hereto bears to the aggregate principal amount of Securities set forth opposite the names of all such non defaulting Initial Purchasers to purchase the Securities which such defaulting Initial Purchaser agreed but failed or refused to purchase on such date. If, on the Closing Date any Initial Purchaser shall fail or refuse to purchase Securities which it or they have agreed to purchase hereunder on such date and the aggregate principal amount of Securities with respect to which such default occurs is more than one tenth of the aggregate principal amount of Securities to be purchased on such date, and arrangements satisfactory to the non-defaulting Initial Purchasers and the Company for the

purchase of such Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of the non-defaulting Initial Purchasers or of the Company or any Guarantor. Any action taken under this Section shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

12. No Fiduciary Relationship. The Company and the Guarantors hereby acknowledge that each Initial Purchaser is acting solely as initial purchaser in connection with the purchase and sale of the Securities. The Company and the Guarantors further acknowledge that the Initial Purchaser is acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm's length basis, and in no event do the parties intend that the Initial Purchaser act or be responsible as a fiduciary to either the Company, the Guarantors or their respective management, stockholders or creditors or any other person in connection with any activity that the Initial Purchaser may undertake or have undertaken in furtherance of the purchase and sale of the Securities, either before or after the date hereof. The Initial Purchasers hereby expressly disclaim any fiduciary or similar obligations to either the Company or the Guarantors, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Company and the Guarantors hereby confirm their understanding and agreement to that effect. The Company, the Guarantors and the Initial Purchasers agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by the Initial Purchasers to the Company and the Guarantors regarding such transactions, including, but not limited to, any opinions or views with respect to the price or market for the Securities, do not constitute advice or recommendations to the Company and the Guarantors. The Company and the Guarantors hereby waive and release, to the fullest permitted by law, any claims that either of the Company or the Guarantors may have against the Initial Purchasers with respect to any breach or alleged breach of any fiduciary or similar duty to the Company or the Guarantors in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.

13. Information Supplied by Initial Purchasers. Each of the Company and the Guarantors hereby acknowledges that, for purposes of Section 4(c) and Section 8, the only information that the Initial Purchasers have furnished to the Company specifically for use in the Preliminary Offering Memorandum or the Final Offering Memorandum are the statements set forth in (a) the first sentence of the fourth paragraph and (b) the third sentence of the fifth paragraph under the caption "Plan of Distribution" in the Preliminary Offering Memorandum and the Final Offering Memorandum.

(b): Beneficiaries. This Agreement has been and is made solely for the benefit of and shall be binding upon the Company, the Guarantors, the Initial Purchasers and to the extent provided in Section 8 hereof, the controlling persons, affiliates, officers, directors, partners, employees, representatives and agents referred to in Section 8 hereof and their respective heirs, executors, administrators, successors and assigns, all as and to the extent provided in this Agreement, and no other person shall acquire or have any right under or by virtue of this Agreement. The term "successors and assigns" shall not include a purchaser of any of the Securities from the Initial Purchasers merely because of such purchase. Notwithstanding the foregoing, it is expressly understood and agreed that each purchaser who purchases Securities from the Initial Purchasers is intended to be a beneficiary of the covenants of the Company and the Guarantors contained in the Registration Rights Agreement to the same extent as if the Securities were sold and those covenants were made directly to such purchaser by the Company and the Guarantors, and each such purchaser shall have the right to take action against the Company and the Guarantors to enforce, and obtain damages for any breach of, those covenants.
(c): Governing Law; Jurisdiction; Waiver of Jury Trial; Venue. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York. Each of the Company and the Guarantors hereby expressly and irrevocably (i) submits to the non-exclusive jurisdiction of the federal and state courts sitting in the Borough of Manhattan in the City of New York in any suit or proceeding arising out of or relating to this Agreement or the Transactions, and (ii) waives (a) its right to a trial by jury in any legal action or proceeding relating to this Agreement, the Transactions or any course of conduct, course of dealing, statements (whether verbal or written) or actions of the Initial Purchasers and for any counterclaim related to any of the foregoing and

(b) any obligation which it may have or hereafter may have to the laying of venue of any such litigation brought in any such court referred to above and any claim that any such litigation has been brought in an inconvenient forum.

(d): Entire Agreement; Counterparts. This Agreement, together with the Engagement Letter, constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.
(e): Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.
(f): Separability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their reasonable best efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.
(g): Amendment. This Agreement may be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may be given, provided that the same are in writing and signed by all of the signatories hereto.
(h): Agreement Among Initial Purchasers. Any action by the Initial Purchasers hereunder may be taken by Jefferies on behalf of the Initial Purchasers, and any such action taken by Jefferies shall be binding upon each of the Initial Purchasers.
