          The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A hereto. The Notes may be issued in the form of Definitive Notes or Global Notes, as specified by the Company. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note shall be dated the date of its authentication. The Notes shall be in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

          The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture and the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

          Notes issued in global form shall be substantially in the form of Exhibit A attached hereto (including the Global Note Legend and the “Schedule of Exchanges in the Global Note” attached thereto). Notes issued in definitive form shall be substantially in the form of Exhibit A attached hereto (but without the Global Note Legend and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby shall be made by the Trustee or the Note Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof.

          The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the “General Terms and Conditions of Clearstream Banking” and “Customer Handbook” of Clearstream shall be applicable to interests in the Regulation S Global Notes that are held by the Agent Members through Euroclear or Clearstream.

Section 2.02 Execution and Authentication.

          Two Officers shall sign the Notes for the Company by manual or facsimile signature.

          If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid.

          A Note shall not be valid until authenticated by the manual signature of the Trustee. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture.

          The Trustee shall, upon a written order of the Company signed by two Officers, authenticate the Initial Notes for original issue up to $1.0 billion in aggregate principal amount and, upon receipt of an authentication order in accordance with this Section 2.02, at any time and from time to time thereafter, the Trustee shall authenticate Additional Notes and Exchange Notes for original issue in an aggregate principal amount specified in such authentication order. Such Additional Notes will be consolidated and form a single series with, and will have the same terms as to ranking, redemption, offers to purchase, waivers, amendments or otherwise as the Initial Notes (except for the issue date and, if applicable, the payment of interest accruing prior to the issue date of such Additional Notes and the first payment of interest following the issue date of such Additional Notes), and will vote together as one class on all matters with respect to the Initial Notes. Issuance of Additional Notes shall not require notice to or the consent of the Holders.

          The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent.

The Company shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture.

          The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium or Special Interest, if any, or interest on the Notes, and will notify the Trustee of any default by the Company in

making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes.

Section 2.05 Holder Lists.

          The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA § 312(a).

     (iii) A Holder of Unrestricted Definitive Notes may transfer such Notes to a Person who takes delivery thereof in the form of an Unrestricted Definitive Note. Upon receipt of a request for such a transfer, the Registrar shall register the Unrestricted Definitive Notes pursuant to the instructions from the Holder thereof. Unrestricted Definitive Notes cannot be exchanged for or transferred to Persons who take delivery thereof in the form of a Restricted Definitive Note.

          (f) Exchange Offer. Upon the occurrence of the Exchange Offer in accordance with the Registration Rights Agreement, the Company shall issue and, upon receipt of an authentication order in accordance with Section 2.02, the Trustee shall authenticate (i) one or more Unrestricted Global Notes in an aggregate principal amount equal to the principal

The Company may request from Holders such information it reasonably determines is required in order to be able to deliver such Officers’ Certificate and Opinion of Counsel. Upon such exchange of beneficial interests pursuant to this Section 2.06(g), the Registrar shall reflect on its books and records the date of such transfer and a decrease and increase, respectively, in the principal amount of the applicable Restricted Global Notes and the Unrestricted Global Notes, respectively, equal to the principal amount of beneficial interests transferred. Following any such transfer pursuant to this Section 2.06(g) of all of the beneficial interests in a Restricted Global Note, such Restricted Global Note shall be cancelled.

          (h) Transfers of Notes Held by Affiliates. Any certificate (i) evidencing a Note that has been transferred to an affiliate (as defined in Rule 405 of the Securities Act) of the Company, as evidenced by a notation on the certificate of transfer and certificate of exchange for such transfer or in the representation letter delivered in respect thereof or (ii) evidencing a Note that has been acquired from an affiliate (other than by an affiliate) in a transaction or a chain of transactions not involving any public offering, shall, until one year after the last date on which either the Company or any affiliate of the Company was an owner of such Note, in each case, be in the form of a permanent definitive security and bear the private placement legend subject to the restrictions in this Section 2.06. The Registrar shall retain copies of all letters, notices and other written communications received pursuant to this Section 2.06. The Company, at its sole cost and expense, shall have the right to inspect and make copies of all such letters, notices or

other written communications at any reasonable time upon the giving of reasonable advance written notice to the Trustee.

          (i) Legends. The following legends shall appear on the face of all Global Notes and Definitive Notes issued under this Indenture unless specifically stated otherwise in the applicable provisions of this Indenture.

“THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THE SECURITY EVIDENCED HEREBY IS HEREBY NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. THE HOLDER OF THE SECURITY EVIDENCED HEREBY AGREES FOR THE BENEFIT OF L-3 COMMUNICATIONS CORPORATION THAT (A) SUCH SECURITY MAY BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1)(a) TO A PERSON WHO THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (b) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144 UNDER THE SECURITIES ACT, (c) OUTSIDE THE UNITED STATES TO A FOREIGN PERSON IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 903 OR 904 UNDER THE SECURITIES ACT OR (d) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL IF L-3 COMMUNICATIONS CORPORATION SO REQUESTS), (2) TO L-3 COMMUNICATIONS CORPORATION OR (3) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT AND, IN EACH CASE, IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER FROM IT OF THE SECURITY EVIDENCED HEREBY OF THE RESALE RESTRICTIONS SET FORTH IN (A) ABOVE.”

     (B) Notwithstanding the foregoing, any Global Note or Definitive Note issued pursuant to subparagraphs (b)(iv), (c)(ii), (c)(iii), (d)(ii), (d)(iii), (e)(ii), (e)(iii) or (f) to this Section 2.06 (and all Notes issued in exchange therefor or substitution thereof) shall not bear the Private Placement Legend.

“THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 2.07 OF THE INDENTURE, (II) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.06(a) OF THE INDENTURE, (III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.11 OF THE INDENTURE AND (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE COMPANY.”

          (j) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note, by the Trustee or by the Depositary at the direction of the Trustee, to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note, by the Trustee or by the Depositary at the direction of the Trustee, to reflect such increase.

          (k) General Provisions Relating to Transfers and Exchanges.

     (i) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Global Notes and Definitive Notes upon the Company’s order or at the Registrar’s request.

     (ii) No service charge shall be made to a holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 4.11 and 9.05 hereof).

     (iii) The Registrar shall not be required to register the transfer of or exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

     (iv) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

     (v) The Company shall not be required (A) to issue, to register the transfer of or to exchange Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date.

     (vi) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary.

     (vii) The Trustee shall authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof.

     (viii) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among depositary participants or beneficial owners of interests in any Global Note) 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 Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Section 2.07 Replacement Notes.

          If any mutilated Note is surrendered to the Trustee, or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon the written order of the Company signed by two Officers of the Company, shall authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note.

          Every replacement Note is an additional obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

Section 2.08 Outstanding Notes.

          The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note.

          If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser.

          If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

          If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest.

Section 2.09 Treasury Notes.

          In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded.

Section 2.10 Temporary Notes.

          Until Definitive Notes are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Notes upon a written order of the Company signed by two Officers of the Company. Temporary Notes shall be substantially in the form of Definitive Notes but may have variations that the Company considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive Notes in exchange for temporary Notes.

          Holders of temporary Notes shall be entitled to all of the benefits of this Indenture.

Section 2.11 Cancellation.

          The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Notes

surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of such canceled Notes (subject to the record retention requirement of the Exchange Act) in its customary manner. Certification of the destruction of all canceled Notes shall be delivered to the Company. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest.

          If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix or cause to be fixed each such special record date and payment date, provided that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

Section 2.13 CUSIP Numbers.

          The Company in issuing the Notes may use CUSIP numbers (if then generally in use), and, if so, the Trustee shall use CUSIP numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the CUSIP numbers.

ARTICLE 3.

Section 3.02 Selection of Notes to Be Redeemed.

          If less than all of the Notes are to be redeemed at any time, the Trustee shall select Notes for redemption on a pro rata basis (or, in the case of Global Notes, based on a method that most nearly approximates a pro rata selection as the Trustee deems fair and appropriate) unless otherwise required by law or applicable stock exchange or depositary requirements; provided

that no Notes of $2,000 or less shall be redeemed in part. Notices of redemption shall be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address. Notices of redemption may not be conditional. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion thereof shall be issued in the name of the Holder thereof upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption.

          The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

Section 3.03 Notice Of Redemption.

          Subject to the provisions of Section 3.09 hereof, at least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address.

          The notice shall identify the Notes to be redeemed (including CUSIP Numbers, if any) and shall state:

(a) the redemption date;

(b) the redemption price;

(c) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note;

(d) the name and address of the Paying Agent;

(e) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

(f) that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date;

(g) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and

(h) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes.

          At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company shall have delivered to the Trustee, at least 5 days prior to the date of the giving of the notice, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

Section 3.04 Effect Of Notice Of Redemption.

          Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional.

Section 3.05 Deposit Of Redemption Price.

          Prior to 11:00 a.m. on the Business Day prior to the redemption date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued interest on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued interest on, all Notes to be redeemed.

          If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.

Section 3.06 Notes Redeemed In Part.

          Upon surrender of a Note that is redeemed in part, the Company shall issue and, upon the Company’s written request, the Trustee shall authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed portion of the Note surrendered.

Section 3.07 Optional Redemption.

          (a) The Company may, at its option, redeem the notes in whole at any time or in part from time to time, on at least 30 but not more than 60 days’ prior notice, at a redemption price equal to the greater of:

     (i) 100% of the principal amount of the Notes being redeemed, and

     (ii) the present value of the Remaining Scheduled Payments on the Notes being redeemed on the redemption date, discounted to the date of redemption, on a semiannual basis, at the Treasury Rate plus 30 basis points.

          (b) If the Company elects to redeem the Notes pursuant to this Section 3.07, it shall also pay accrued and unpaid interest (including Special Interest), if any, to the date of redemption, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date.

          (c) In determining the redemption price and accrued interest pursuant to this Section 3.07, interest will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

Section 3.08 Mandatory Redemption.

          Except as set forth under Section 4.11, the Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

          The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

          The Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 2.03.

     (ii) all current reports on Form 8-K required to be filed by companies that are subject to the periodic reporting requirements of the Exchange Act.

          (b) If, at any time, the Company is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Company shall nevertheless continue to prepare the financial statements and a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” substantially similar to that which would have been required to be included in each of the reports specified in clause (i) of Section 4.03(a) had the Company been subject to such Exchange Act reporting requirements (with all such financial statements prepared in accordance with Regulation S-X promulgated by the SEC and all such annual financial statements, including a report thereon from the Company’s certified independent accountants) and post copies thereof to its website for public availability within the time periods that would have been applicable to filing such reports with the SEC in the rules and regulations applicable to such reports if the Company had been required to file those reports with the SEC; provided, however, that if the Company is no longer subject to the periodic reporting requirements of the Exchange Act, the Company shall not be required to comply with Section 302 or Section 404 of the Sarbanes-Oxley Act of 2002, or related Items 307 and 308 of Regulation S-K promulgated by the SEC, or Item 10(e) of Regulation S-K (with respect to any non-GAAP financial measures contained therein).

          (d) The Company shall furnish (or cause the Trustee to furnish) to Holders, prospective investors, broker-dealers and securities analysts, upon their request, any information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as the Notes are not freely transferable under the Securities Act.

          (e) Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

Section 4.04 Compliance Certificate.

          (a) The Company shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officers’ Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of or interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action the Company is taking or proposes to take with respect thereto.

          (b) The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee, as soon as possible and in any event within five Business Days after any Officer becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto.

Section 4.05 Taxes.

          The Company shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are

contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.

Section 4.06 Stay, Extension and Usury Laws

          The Company and each of the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and, to the extent that it may lawfully do so, the Company and each of the Guarantors hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted.

Section 4.07 Sale and Leaseback Transactions.

     The Company will not, and will not permit any of its Subsidiaries to, enter into any arrangement with any other Person pursuant to which the Company or any of its Subsidiaries leases any property that has been or is to be sold or transferred by the Company or the Subsidiary to such other Person (a “Sale and Leaseback Transaction”), except that a Sale and Leaseback Transaction is permitted if the Company or such Subsidiary would be entitled to incur Indebtedness secured by a Lien on the property to be leased (without equally and ratably securing the Notes) in an aggregate principal amount equal to the Attributable Debt with respect to such Sale and Leaseback Transaction.

     In addition, the following Sale and Leaseback Transactions are not subject to the limitation in the immediately preceding paragraph and the provisions described in Section 4.08:

     (i) temporary leases for a term, including renewals at the option of the lessee, of not more than three years;

     (iv) leases of property executed by the time of, or within 270 days after the latest of, the acquisition, the completion of construction or improvement, or the commencement of commercial operation, of the subject property.

Section 4.08 Liens.

          The Company shall not, and shall not permit any of its Wholly Owned Domestic Subsidiaries to, create, incur, assume or permit to exist any Lien (except Permitted Liens) on (1) any Principal Property or (2) the Capital Stock of any Subsidiary, in each case to secure Indebtedness of the Company, any Subsidiary of the Company or any other Person, unless the Notes are secured, equally and ratably with such other Indebtedness (or on a senior basis if the Obligations so secured are subordinated Indebtedness), for so long as such other Indebtedness is so secured. Any Lien that is granted to secure the Notes pursuant to this Section 4.08 shall be automatically released and discharged at the same time as the release of the Lien that gave rise to the obligation to secure the Notes pursuant to this Section 4.08.

Section 4.09 Future Subsidiary Guarantees.

          (a) If the Company or any of its Subsidiaries acquires or creates a Domestic Subsidiary after the Issue Date, including if a Subsidiary that is not a Domestic Subsidiary becomes a Domestic Subsidiary after the Issue Date, and such Domestic Subsidiary guarantees any other Indebtedness of the Company, then such Domestic Subsidiary will become a Guarantor and will execute a supplemental indenture and deliver an Opinion of Counsel satisfactory to the Trustee within thirty (30) Business Days of the date on which it was acquired or created. The obligations of each Guarantor under its Subsidiary Guarantee will be limited so as not to constitute a fraudulent conveyance under applicable law.

          (b) If any Guarantor that is released from its Subsidiary Guarantee pursuant to Section 10.04 thereafter guarantees any Indebtedness of the Company (other than the Notes), then that former Guarantor (to the extent it is a Domestic Subsidiary) shall again guarantee the Notes on the terms and conditions set forth in this Indenture.

integral multiple of $1,000 in excess thereof) of such Holder’s Notes pursuant to the offer described below (the “Change of Control Offer ”) at an offer price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest and Special Interest, if any, to the date of purchase (the “Change of Control Payment ”), subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date; provided, that the Company will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in Article III and this Section 4.11 applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

All remedies are cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults.

          Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium or Special Interest, if any, or interest on, the Notes including in connection with an offer to purchase; provided, however, that the Holders of a majority in aggregate principal amount at maturity of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration.

Section 6.05 Control By Majority.

(e) during such 60-day period the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request.

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note.

Section 6.07 Rights of Holders of Notes to Receive Payment.

          Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium and Special Interest, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 6.08 Collection Suit by Trustee.

          If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium and Special Interest, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities.

          (m) in no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

Section 7.03 Individual Rights of Trustee.

          The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

Section 7.04 Trustee’s Disclaimers.

Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes.

Section 7.06 Reports by Trustee to Holders of the Notes.

          Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted).

determined to have been caused by its own negligence or willful misconduct. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense.

          If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee (at the Company’s expense), the Company, or the

Holders of Notes of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

          If the Trustee, after written request by any Holder of a Note who has been a Holder of a Note for at least six months, fails to comply with Section 7.10, such Holder of a Note may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

ARTICLE 8.
LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

          The Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, at any time, elect to have either Section 8.02 or

8.03 hereof be applied to all outstanding Notes and the Subsidiary Guarantees upon compliance with the conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

          Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their respective obligations with respect to all outstanding Notes (including the Subsidiary Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive solely from the trust fund described in Section 8.04 hereof, and as more fully set forth in such Section, payments in respect of the principal of, premium and Special Interest, if any, and interest on such Notes when such payments are due, (b) the Company’s obligations with respect to such Notes under Sections 2.06, 2.07, 2.10 and 4.02 hereof, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s and the Subsidiary Guarantors obligations in connection therewith and (d) this Article 8. Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

Section 8.03 Covenant Defeasance.

          Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and the Guarantors, as applicable, shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations under Sections 4.03, 4.07, 4.08, 4.09, 4.11 and Article 5 hereof with respect to the outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company and the Guarantors, as applicable, may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction

of the conditions set forth in Section 8.04 hereof, Sections 6.01(d) through 6.01(f) hereof shall not constitute Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

(a) the Company must irrevocably deposit with the trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium and interest (including Special Interest, if any) on the outstanding Notes on the Stated Maturity thereof;

(b) in the case of an election under Section 8.02 hereof, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(c) in the case of an election under Section 8.03 hereof, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(d) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings);

(e) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(f) the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and

(g) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

          Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to Company.

          Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium and Special Interest, if any, or interest on any Note and remaining unclaimed for two years after such principal, premium and Special Interest, if any, or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as a secured creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in The New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 8.07 Reinstatement.

          If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors,’ as applicable, obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE 9.
AMENDMENT, SUPPLEMENT AND WAIVER

(a) to cure any ambiguity, defect or inconsistency;

(b) to provide for uncertificated Notes in addition to or in place of certificated Notes;

(c) to provide for the assumption of the Company’s obligations to the Holders of the Notes in the case of a merger or consolidation pursuant to Article 5 hereof;

(d) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any Holder of the Note;

(e) to secure the Notes or to add additional Guarantors;

(f) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; or

(g) to conform the text of this Indenture or the Notes to any provision of the “Description of the Notes” section of the Company’s Offering Memorandum, dated September 29, 2009, related to the initial offering of the Notes, to the extent that such provision in that “Description of the Notes” section was intended to be a verbatim recitation of a provision of this Indenture, the Subsidiary Guarantees or the Notes.

          Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company in the execution of any amended or supplemental Indenture authorized or

permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental Indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

Section 9.02 With Consent of Holders of Notes.

          Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture (including Sections 3.09 and 4.11 hereof) and the Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes).

          Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental Indenture.

          The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Persons entitled to consent to any indenture supplemental hereto. If a record date is fixed, the Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to consent to such supplemental indenture, whether or not such Holders remain Holders after such record date; provided, that unless such consent shall have become effective by virtue of the requisite percentage having been obtained prior to the date which is 180 days after such record date, any such consent previously given shall automatically and without further action by any Holder be canceled and of no further effect.

          It shall not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof.

          After an amendment, supplement or waiver under this Section becomes effective, the Company shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a

majority in aggregate principal amount of the Notes then outstanding may waive compliance in a particular instance by the Company with any provision of this Indenture or the Notes. However, without the consent of each Holder affected, an amendment or waiver may not (with respect to any Notes held by a non-consenting Holder):

(a) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver;

(b) reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption of the Notes except as provided above with respect to Section 4.11 hereof;

(c) reduce the rate of or change the time for payment of interest, including default interest, on any Note;

(d) waive a Default or Event of Default in the payment of principal of, or premium and Special Interest, if any, or interest on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration);

(e) make any Note payable in money other than that stated in the Notes;

(f) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of or premium and Special Interest, if any, or interest on the Notes;

(g) waive a redemption payment with respect to any Note (other than a payment required by Sections 3.09 and 4.11 hereof); or

(h) make any change in Section 6.04 or 6.07 hereof or in the foregoing amendment and waiver provisions.

Section 9.03 Compliance with Trust Indenture Act.

          Every amendment or supplement to this Indenture or the Notes shall be set forth in a amended or supplemental Indenture that complies with the TIA as then in effect.

Section 9.04 Revocation and Effect of Consents.

          Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

Section 9.05 Notation on or Exchange of Notes.

          The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver.

          Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

Section 9.06 Trustee to Sign Amendments, Etc.

          The Trustee shall sign any amended or supplemental Indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amendment or supplemental indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be provided with and (subject to Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

ARTICLE 10.

          Each of the Guarantors hereby agrees as follows:

          (a) Such Guarantor, jointly and severally with all other Guarantors, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee its successors and assigns, regardless of the validity and enforceability of this Indenture, the Notes or the Obligations of the Company under this Indenture or the Notes, that:

     (i) the principal of, premium, interest and Special Interest, if any, on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium, interest and Special Interest, if any, on the Notes, to the extent lawful, and all other Obligations of the Company to the Holders or the Trustee thereunder or under this Indenture will be promptly paid in full, all in accordance with the terms thereof; and

relevant jurisdiction, the liability of the Guarantors under this Indenture shall be reduced to the maximum amount permissible under such fraudulent conveyance or similar law.

Section 10.02 Execution and Delivery of Subsidiary Guarantees.

          (a) The Subsidiary Guarantee of a Guarantor shall be evidenced by the execution and delivery of this Indenture by an Officer of such Guarantor.

          (c) The delivery of any Note by the Trustee, after the authentication thereof under this Indenture, shall constitute due delivery of the Guarantee set forth in this Indenture on behalf of each Guarantor.

          (d) Each Guarantor hereby agrees that its obligations hereunder shall be unconditional, regardless of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor.

          (e) Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that its Guarantee made pursuant to this Indenture will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

          (f) If any Holder or the Trustee is required by any court or otherwise to return to the Company or any Guarantor, or any custodian, Trustee, liquidator or other similar official acting in relation to either the Company or such Guarantor, any amount paid by either to the Trustee or such Holder, the Guarantee made pursuant to this Indenture, to the extent theretofore discharged, shall be reinstated in full force and effect.

          (g) Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between such Guarantor, on the one hand, and the Holders and the Trustee, on the other hand:

shall forthwith become due and payable by such Guarantor for the purpose of the Guarantee made pursuant to this Indenture.

          (h) Each Guarantor shall have the right to seek contribution from any other non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders or the Trustee under the Guarantee made pursuant to this Indenture.

Section 10.03 Guarantors May Consolidate, Etc. on Certain Terms.

          (a) Except as set forth in Article 5 of this Indenture, nothing contained in this Indenture or in the Notes shall prevent any consolidation or merger of any Guarantor with or into the Company or any other Guarantor or shall prevent any transfer, sale or conveyance of the property of any Guarantor as an entirety or substantially as an entirety, to the Company or any other Guarantor.

          (b) Except as set forth in Article 5 of this Indenture, nothing contained in this Indenture or in the Notes shall prevent any consolidation or merger of any Guarantor with or into any entity other than the Company or any other Guarantor (in each case, whether or not affiliated with the Guarantor), or successive consolidations or mergers in which a Guarantor or its successor or successors shall be a party or parties, or shall prevent any sale or conveyance of the property of any Guarantor as an entirety or substantially as an entirety, to any entity other than the Company or any other Guarantor (in each case, whether or not affiliated with the Guarantor) authorized to acquire and operate the same; provided, however, that no Guarantor may consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person (except the Company or another Guarantor) unless: (i) subject to the provisions of Section 10.04(c), the Person formed by or surviving any such consolidation or merger (if other than such Guarantor) assumes all the obligations of such Guarantor under the Notes and this Indenture pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee; and (ii) immediately after giving effect to such transaction, no Default or Event of Default exists.

          (c) In case of any consolidation, merger, sale or conveyance in which the successor entity assumes all the obligations of a Guarantor under the Notes and this Indenture pursuant to the proviso to Section 10.03(b), such successor entity shall succeed to and be substituted for such Guarantor with the same effect as if it had been named herein as one of the Guarantors. Such successor entity thereupon may cause to be signed any or all of the Guarantees to be endorsed upon the Notes issuable under this Indenture which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Guarantees so issued shall in all respects have the same legal rank and benefit under this Indenture as the Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Guarantees had been issued at the date of the execution hereof.

Section 10.04 Releases.

          (a) Upon the release of all guarantees by a Guarantor under all the outstanding Indebtedness of the Company (other than the Notes) that is guaranteed by that Guarantor, the

Subsidiary Guarantee of that Guarantor will automatically and unconditionally be released and discharged, without any further action required by such Guarantor or the Trustee.

          (b) The Subsidiary Guarantee of any Guarantor shall automatically and unconditionally be released and discharged, without any further action required by such Guarantor or the Trustee, if at any time such Guarantor is no longer a Domestic Subsidiary.

          (c) In the event of a sale or other disposition of all of the assets of any Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of stock of any Guarantor such that the Guarantor is no longer a Subsidiary of the Company, then such Guarantor (in the event of a sale or other disposition, by way of such a merger, consolidation or otherwise) or the entity acquiring the property (in the event of a sale or other disposition of all of the assets of such Guarantor) shall be automatically and unconditionally released and relieved of any obligations under its Subsidiary Guarantee, without any actions required on the part of the Guarantor or Trustee.

Section 10.05 No Recourse Against Others.

          No past, present or future director, officer, employee, incorporator, stockholder or agent of any Subsidiary of the Company, as such, shall have any liability for any obligations of the Company or any Subsidiary of the Company under the Notes, any Guarantees, this Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the Securities and Exchange Commission that such a waiver is against public policy.

EACH PURCHASER OF THE SECURITY EVIDENCED HEREBY IS HEREBY NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER.

THE SECURITY EVIDENCED HEREBY OF THE RESALE RESTRICTIONS SET FORTH IN (A) ABOVE.

          Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

     1. Interest. L-3 Communications Corporation, a Delaware corporation (the “Company”), promises to pay interest on the principal amount of this Note at 5.20% per annum from October 2, 2009 until maturity and shall pay the Special Interest payable pursuant to Section 5 of the Registration Rights Agreement referred to below. The Company will pay interest and Special Interest, if any, semi-annually on April 15 and October 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”), with the same force and effect as if made on the date for such payment. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from 1:00 p.m. October 2, 2009; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be April 15, 2010.

     2. Method Of Payment. The Company will pay interest on the Notes (except defaulted interest) and Special Interest, if any, to the Persons who are registered Holders of Notes at the close of business on the April 1 and October 1 next (whether or not a Business Day) preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium and Special Interest, if any, and interest at the office or agency of the Company maintained for such purpose within The City and State of New York, or, at the option of the Company, payment of interest and Special Interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest, premium and Special Interest on, all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Company or the Paying Agent if such Holders shall be registered Holders of at least $250,000 in principal amount of the Notes. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

     3. Paying Agent And Registrar. Initially, The Bank of New York Mellon, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

     4. Indenture. The Company issued the Notes under an Indenture dated as of October 2, 2009 (“Indenture”) among the Company, the Guarantors named therein and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and

such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

     5. Optional Redemption.

          (a) The Company may, at its option, redeem the Notes in whole at any time or in part from time to time, on at least 30 but not more than 60 days’ prior notice, at a redemption price equal to the greater of:

     (i) 100% of the principal amount of the Notes being redeemed, and

     (ii) the present value of the Remaining Scheduled Payments on the Notes being redeemed on the redemption date, discounted to the date of redemption, on a semiannual basis, at the Treasury Rate plus 30 basis points.

          (b) If the Company elects to redeem the Notes, it will also pay accrued and unpaid interest (including Special Interest), if any, to the date of redemption, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date. In determining the redemption price and accrued interest, interest will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

     6. Mandatory Redemption.

          Except as set forth in paragraph 7 below, the Company shall not be required to make mandatory redemption payments with respect to the Notes.

     7. Repurchase At Option Of Holder.

          Upon the occurrence of a Change of Control Triggering Event, unless the Company has exercised its right to redeem the Notes as described above, each Holder will have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s Notes pursuant to the offer described below (the “Change of Control Offer ”) at an offer price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest and Special Interest, if any, to the date of purchase (the “Change of Control Payment ”), subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date; provided, that the Company will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. Within 30 days following the date upon which any Change of Control Triggering Event occurs, or at the Company’s option, prior to any Change of Control Triggering Event but subject to the occurrence of a Change of Control Triggering Event, the Company will mail a notice to each Holder describing the events constituting a Change of Control Triggering Event (including the transaction or transactions that constitute the Change of Control) and offering to repurchase Notes on the date specified in such notice, which date will be no earlier than 30 days and no later than 60 days from the date such

notice is mailed (the “Change of Control Payment Date”), pursuant to the procedures required by the Indenture and described in such notice. The notice, if mailed prior to the occurrence of the Change of Control Triggering Event, will state that the Change of Control Offer is conditioned on the occurrence of a Change of Control Triggering Event on or prior to the Change of Control Payment Date. The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event.

     8. Notice Of Redemption. Notice of redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date interest ceases to accrue on Notes or portions thereof called for redemption.

     9. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, it need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date.

     10. Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes.

     11. Amendment, Supplement And Waiver. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the then outstanding Notes, and any existing default or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes). Without the consent of any Holder of a Note, the Indenture or the Notes may be amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company’s obligations to Holders of the Notes in case of a merger or consolidation, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder, to secure the Notes or to add additional Guarantors, to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act or to conform the text of the Indenture or the Notes to any provision in the Offering Memorandum, dated September 29, 2009, with respect to the Notes, under the caption “Description of the Notes,” to the extent

that such provision was intended to be a verbatim recitation of the Indenture, the Subsidiary Guarantees or the Notes.

     12. Defaults And Remedies. An “Event of Default” occurs if: (i) default for 30 days in the payment when due of interest (including Special Interest, if any) with respect to, the Notes; (ii) default in payment when due of the principal of or premium, if any, on the Notes; (iii) failure by the Company to comply with the covenants contained in sections 4.11 or 5.01 of the Indenture; (iv) failure by the Company to comply with any of its other agreements in the Indenture or the Notes for 90 days after written notice is received by the Company and the Trustee from the Holders of at least 25% in aggregate principal amount of the Notes then outstanding; (v) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness of the Company or any of its Subsidiaries (or the payment of which is guaranteed by the Company or any of its Subsidiaries) whether such Indebtedness or guarantee now exists, or is created after the Issue Date, which default relates to a payment at final maturity or results in the acceleration of such Indebtedness prior to its express maturity and, in each case, the principal amount of such Indebtedness, together with the principal amount of all other Indebtedness that is not paid at final maturity or results in the maturity of which has been so accelerated, aggregates $100.0 million or more; (vi) failure by the Company or any of its Subsidiaries to pay final judgments aggregating in excess of $100.0 million, which judgments are not paid, discharged or stayed for a period of 60 days; (vii) certain events of bankruptcy or insolvency with respect to the Company or any of its Significant Subsidiaries; and (viii) except as permitted by the Indenture, any Subsidiary Guarantee of a Significant Subsidiary shall be held in any judicial proceeding to be unenforceable or invalid.

     If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, with respect to the Company or any Significant Subsidiary, all outstanding Notes will become due and payable without further action or notice. Holders of the Notes may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal, premium or interest, including Special Interest, if any) if it determines that withholding notice is in their interest.

     The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest on, or the principal of, the Notes.

     13. Trustee Dealings With Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee.

     14. No Recourse Against Others. A director, officer, employee, incorporator or stockholder, of the Company or any Subsidiary of the Company, as such, shall not have any liability for any obligations of the Company or any Subsidiary of the Company under the Notes, the Indenture or the Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.

Such Guaranteeing Subsidiary, jointly and severally with all other current and future guarantors of the Notes (collectively, the “Guarantors” and each, a “Guarantor”), unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, regardless of the validity and enforceability of the Indenture, the Notes or the Obligations of the Company under the Indenture or the Notes, that:

(i)

the principal of, premium, interest and Special Interest, if any, on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium, interest and Special Interest, if any, on the Notes, to the extent lawful, and all other Obligations of the Company to the Holders

	(d)		The delivery of any Note by the Trustee, after the authentication thereof under the Indenture, shall constitute due delivery of the Subsidiary Guarantee set forth in this Supplemental Indenture on behalf of each Guaranteeing Subsidiary.

	(f)		Each Guaranteeing Subsidiary hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that its Subsidiary Guarantee made pursuant to this Supplemental Indenture will not be discharged except by complete performance of the Obligations contained in the Notes and the Indenture.

	(i)		Each Guaranteeing Subsidiary shall have the right to seek contribution from any other non-paying Guaranteeing Subsidiary so long as the exercise of such right does not impair the rights of the Holders or the Trustee under the Subsidiary Guarantee made pursuant to this Supplemental Indenture.

	(c)		In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor entity, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Subsidiary Guarantee made pursuant to this Supplemental Indenture and the due and punctual performance of all of the covenants and conditions of the Indenture and this Supplemental Indenture to be performed by such Guaranteeing Subsidiary, such successor entity shall succeed to and be substituted for such Guaranteeing Subsidiary with the same effect as if it had been named herein as the Guaranteeing Subsidiary. Such successor entity thereupon may cause to be signed any or all of the Subsidiary Guarantees to be endorsed upon the Notes issuable under the Indenture which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Subsidiary Guarantees so issued shall in all respects have the same legal rank and benefit under the Indenture and this Supplemental Indenture as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of the Indenture and this Supplemental Indenture as though all of such Subsidiary Guarantees had been issued at the date of the execution hereof.
	5.		Releases.
	(a)		Upon the release of a Guarantor from its Guarantees of, and all pledges and security interests granted in connection with, all other Indebtedness of the Company, such Guaranteeing Subsidiary shall be released and relieved of its Obligations under its Subsidiary Guarantee and this Supplemental Indenture. Any Guaranteeing Subsidiary not released from its Obligations under its Subsidiary Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the other Obligations of any Guaranteeing Subsidiary under the Indenture as provided herein.

(b)

Each Guaranteeing Subsidiary shall be released and relieved of its obligations under this Supplemental Indenture in accordance with, and subject to, Sections 4.09 and 10.04 of the Indenture.

     6. No Recourse Against Others. No past, present or future director, officer, employee, incorporator, stockholder or agent of any Subsidiary of the Company, as such, shall have any liability for any Obligations of the Company or any Subsidiary of the Company under the Notes, any Subsidiary Guarantees, the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such Obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy.

     7. NEW YORK LAW TO GOVERN. THIS SUPPLEMENTAL INDENTURE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

     8. Counterparts. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.

     9. Effect Of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof.

     10. The Trustee. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Subsidiaries and the Company.

          IN WITNESS WHEREOF, the parties hereto have caused this Supplemental Indenture to be duly executed, all as of the date first above written.
