Item 1.01               Entry into a Material Definitive Agreement

Issuance and Sale of New Notes and Execution of Second Supplemental Indenture

On February 7, 2007, TransDigm Inc. (“TransDigm”), a wholly-owned subsidiary of TransDigm Group Incorporated (“TD Group”), issued and sold $300 million aggregate principal amount of its 7 ¾% Senior Subordinated Notes due 2014 (the “New Notes”) to Credit Suisse Securities (USA) LLC and Lehman Brothers Inc. (the “Initial Purchasers”).  The New Notes were issued by TransDigm pursuant to that certain Indenture, dated as of June 23, 2006 (as supplemented from time to time, the “Indenture”), by and among TD Group, TransDigm, the subsidiaries of TransDigm named therein and The Bank of New York Trust Company, N.A., as trustee (the “Trustee”).  The terms of the New Notes are substantially identical to the terms of the 7 ¾% Senior Subordinated Notes due 2014 that were issued and sold by TransDigm on June 23, 2006 pursuant to the terms of the Indenture (the “Existing Notes” and, together with the New Notes, the “Notes”).  The New Notes will be treated under the Indenture as a single class of notes with the Existing Notes, including for purposes of waivers, amendments, redemptions and offers to purchase.  Certain material terms and conditions of the Indenture and the Notes were described in the Current Report on Form 8-K that was filed by TD Group with the Securities and Exchange Commission on June 28, 2006 (the “Prior 8-K”), and such description is incorporated herein by reference.

TransDigm used the proceeds from the issuance and sale of the New Notes, together with the proceeds from its borrowing pursuant to the Additional Term Loan (as defined in the Amendment (as defined below)) and a portion of its available cash balances to fund the ATI Acquisition (as defined below) and to pay related transaction expenses.

As further described under Item 2.01 below, on February 7, 2007, TransDigm completed the ATI Acquisition.  In connection with the consummation of the ATI Acquisition, and in accordance with the terms of the Indenture, TransDigm, TD Group, the subsidiaries of TransDigm named therein, ATI (as defined below) and its direct and indirect subsidiaries, Avtech Corporation, Transicoil Corp., West Coast Specialties, Inc. and Malaysian Aerospace Services, Inc. (such subsidiaries and ATI are collectively referred to herein as the “ATI Entities”) and the Trustee entered into that certain Second Supplemental Indenture to the Indenture (the “Supplemental Indenture”), dated as of February 7, 2007.  Pursuant to the terms of the Supplemental Indenture, the ATI Entities agreed to become Guarantors (as defined in the Indenture) under the Indenture for all purposes thereof and to be bound by the terms applicable to Guarantors thereunder; accordingly, pursuant to the terms of the Supplemental Indenture, each of the ATI Entities agreed to, among other things, guarantee all of the indebtedness of TransDigm outstanding from time to time under the Indenture, including in respect of the New Notes.

The above summary of the Supplemental Indenture is qualified in its entirety by reference to the Supplemental Indenture, which is attached hereto as Exhibit 10.1 and incorporated herein by reference.

On February 7, 2007, TransDigm, TD Group and the subsidiaries of TransDigm named therein (including the ATI Entities) entered into that certain Registration Rights Agreement (the “Registration Rights Agreement”) with the Initial Purchasers.  Pursuant to the terms of the Registration Rights Agreement, TransDigm, TD Group and the subsidiaries of TransDigm named therein (including the ATI Entities) have agreed to, among other things, file with the Securities and Exchange Commission, within 180 days of the closing of the sale of the New Notes, a registration statement (the “Registration Statement”) to allow the holders of the New Notes to exchange the New Notes for registered notes with substantially identical terms as the New Notes and evidencing the same indebtedness of TransDigm as the New Notes.  TransDigm, TD Group and the subsidiaries of TransDigm named therein (including the ATI Entities) are further obligated under the terms of the Registration Rights Agreement to use their reasonable best efforts to cause the Registration Statement to become effective under the Securities Act of 1933, as amended, within 270 days of the closing of the sale of the New Notes.  If the foregoing obligations in respect of the Registration Statement are not complied with or if certain other events occur (as specified in the Registration Rights Agreement), TransDigm may be required to pay additional interest, as calculated in the Registration Rights Agreement, with respect to the New Notes.

The above summary of the Registration Rights Agreement is qualified in its entirety by reference to the Registration Rights Agreement, which is attached hereto as Exhibit 10.2 and incorporated herein by reference.

Amendment to the Credit Agreement

In connection with the ATI Acquisition, TransDigm, TD Group, the subsidiaries of TransDigm named therein, Credit Suisse, as administrative agent and collateral agent, and the other agents and lenders named therein entered into Amendment No. 1, Consent and Agreement (the “Amendment”), dated as of January 25, 2007, to the Credit Agreement, dated as of June 23, 2006 (the “Credit Agreement”), among TransDigm, TD Group, the subsidiaries of TransDigm named therein, Credit Suisse and the other agents and lenders named therein.

Pursuant to the terms of the Amendment, on February 7, 2007, each Additional Term Lender (as defined in the Amendment) made an Additional Term Loan (as defined in the Amendment) to TransDigm in an aggregate principal amount of $130 million.  As disclosed above, TransDigm used the proceeds from the Additional Term Loan, together with the proceeds from the issuance and sale of the New Notes and a portion of its available cash balances to fund the ATI Acquisition and to pay related transaction expenses.  The Additional Term Loan is governed by the terms of the Credit Agreement, as amended by the Amendment.  Certain material terms and conditions of the Credit Agreement were described in the Prior 8-K, and such description is incorporated herein by reference.

In addition, pursuant to the terms of the Amendment, and effective as of the closing date of the ATI Acquisition, the Revolving Credit Commitment (as defined in the Credit Agreement) was increased by $50 million, resulting in an aggregate Revolving Credit Commitment under the Credit Agreement of $200 million, of which approximately $198.8 million is available as of the

3

The Amendment also provided for a modification to the terms of the secured debt covenant that is contained in the Credit Agreement.  Under the terms of the Credit Agreement, the ratio (the “Secured Debt Ratio”) of (a) total indebtedness of TransDigm on a consolidated basis on the applicable determination date that is secured by first-priority liens on the same collateral as the collateral securing the indebtedness outstanding under the Credit Agreement to (b) Consolidated EBITDA (as defined in the Credit Agreement) for a period of four consecutive fiscal quarters most recently ended on or prior to the applicable determination date may not be greater than certain specified ratios.  Pursuant to the terms of the Amendment, the Secured Debt Ratio was modified as follows: (i) for the period from June 30, 2006 through December 31, 2006, the Secured Debt Ratio may not be greater than 4.75 to 1.00; (ii) for the period from January 1, 2007 through September 30, 2007, the Secured Debt Ratio may not be greater than 5.50 to 1.00; (iii) for the period from October 1, 2007 through June 30, 2008, the Secured Debt Ratio may not be greater than 5.25 to 1.00; (iv) for the period from July 1, 2008 through December 31, 2008, the Secured Debt Ratio may not be greater than 4.75 to 1.00; and (v) after December 31, 2008, the Secured Debt Ratio may not be greater than 4.50 to 1.00.

The above summary of the Amendment is qualified in its entirety by reference to the Amendment, which is attached hereto as Exhibit 10.3 and incorporated herein by reference.

Joinder Agreement and Supplement to Guarantee and Collateral Agreement

In connection with the consummation of the ATI Acquisition, and in accordance with the terms of the Credit Agreement and the related Guarantee and Collateral Agreement, dated as of June 23, 2006, among TransDigm, TD Group, Credit Suisse, as administrative agent and collateral agent, and the other parties named therein (as supplemented from time to time, the “Guarantee and Collateral Agreement”), the ATI Entities and Credit Suisse entered into (x) Supplement No. 2 to the Guarantee and Collateral Agreement (“Supplement No. 2”) and (y) a Joinder Agreement to the Credit Agreement (the “Joinder Agreement”).  Pursuant to the terms of Supplement No. 2, the ATI Entities agreed to, among other things, guarantee all of the indebtedness of TransDigm outstanding under the Credit Agreement from time to time, including in respect of the Additional Term Loan.  In addition, under the terms of Supplement No. 2, the ATI Entities pledged substantially all of their assets to secure their guaranteed obligations under the Credit Agreement.  Pursuant to the terms of the Joinder Agreement, each ATI Entity has agreed that it will deemed to be a “Loan Party” and a “Loan Guarantor” for all purposes of the Credit Agreement.

The above summary of Supplement No. 2 and the Joinder Agreement is qualified in its entirety by reference to Supplement No. 2 and the Joinder Agreement, which are attached hereto as Exhibits 10.4 and 10.5, respectively, and incorporated herein by reference.

Item 2.01               Completion of Acquisition or Disposition of Assets

On February 7, 2007, pursuant to the terms and that certain Agreement and Plan of Merger, dated as of January 9, 2007 (the “Merger Agreement”), among TransDigm, Project Coffee Acquisition Co. (“Merger Sub”) and Aviation Technologies, Inc. (“ATI”), Merger Sub

4

merged with and into ATI, with ATI continuing as the surviving corporation and a wholly-owned subsidiary of TransDigm (the “ATI Acquisition”).  The purchase price paid by TransDigm in connection with this transaction was approximately $430 million.  A copy of the Merger Agreement was filed by TD Group with the Securities and Exchange Commission on a Current Report on Form 8-K on January 10, 2007.  ATI, which is based in Seattle, WA, supplies innovative aerospace products to a diverse fleet of commercial and military aircraft, including the entire fleet of Boeing commercial aircraft, the Airbus A380 and A320, Embraer and Canadair regional jets as well as a broad range of business jets.  Prior to the ATI Acquisition, the stock of ATI was held primarily by Odyssey Investment Partners (“Odyssey”) and related parties.

As previously disclosed, Odyssey was the principal owner of TransDigm prior to July 2003.  Based on their working relationship with Odyssey arising from Odyssey’s investment in TransDigm, Mr. W. Nicholas Howley, Chairman and Chief Executive Officer of TransDigm Group, and Mr. Douglas Peacock, a director of TransDigm Group, co-invested with Odyssey in ATI in 2003.  Each of Mr. Howley and Mr. Peacock indirectly owned less than one-half of 1% of ATI’s outstanding equity on a fully diluted basis.  In addition, because of their working relationship and their expertise in the aerospace industry, Odyssey asked both Mr. Howley and Mr. Peacock to serve on ATI’s board of directors.  Prior to the ATI Acquisition, Mr. Howley and Mr. Peacock were directors of ATI commencing in 2003, and Mr. Peacock served as ATI’s Chairman during that time.  Due to the relationship of Mr. Howley and Mr. Peacock with ATI, the ATI Acquisition was evaluated and recommended by a special committee of disinterested directors of the board of directors of TD Group.  In addition, Messrs. Howley and Peacock abstained from the vote of the full board of directors of TD Group in approving the transaction.

WHEREAS, the Company and the Existing Guarantors have heretofore executed and delivered to the Trustee an indenture (as supplemented by the First Supplemental Indenture thereto, dated as of November 2, 2006, the “INDENTURE”), dated as of June 23, 2006, providing for the issuance by the Company of 7-3/4% Senior Subordinated Notes due 2014 (the “NOTES”) and the guarantees thereof by each of the Existing Guarantors;

WHEREAS, the Indenture provides that under certain circumstances described therein, newly created or acquired Domestic Restricted Subsidiaries shall execute and deliver to the Trustee a supplemental indenture to the Indenture providing for a senior subordinated guarantee of payment of the Notes by such Domestic Restricted Subsidiary (the “SUBSIDIARY GUARANTEE”); and

WHEREAS, pursuant to Section 9.01(g) of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture without the consent of the Holders Notes.

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiaries covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:

1.  CAPITALIZED TERMS.  Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.

Dear Sirs:

TransDigm Inc., a Delaware corporation (the “Issuer”), proposes to issue and sell to the several initial purchasers (collectively, the “Initial Purchasers”) listed on Schedule A to a purchase agreement, dated January 31, 2007 (the “Purchase Agreement”), upon the terms set forth in such Purchase Agreement, $300,000,000 aggregate principal amount of its 7¾% Senior Subordinated Notes due 2014 (the “Initial Securities”) to be unconditionally guaranteed (the “Guarantees”) by TransDigm Group Incorporated and the subsidiaries of the Issuer listed on Schedule I hereto (such subsidiaries are hereinafter collectively referred to as the “Company Guarantors”) and, immediately following the Merger (as defined in the Purchase Agreement), by the parties listed on Schedule II hereto (the “ATI Guarantors”).  TransDigm Group Incorporated, the Company Guarantors and the ATI Guarantors are collectively referred to herein as the “Guarantors” and the Issuer and the Guarantors are collectively referred to herein as the “Company”.  The Initial Securities will be issued as additional securities under the Indenture, dated as of June 23, 2006 (as supplemented from time to time, the “Indenture”), among the Issuer, the Guarantors and The Bank of New York Trust Company, N.A., a national banking association, as trustee (the “Trustee”).  As an inducement to the Initial Purchasers, the Company agrees with the Initial Purchasers, for the benefit of the holders of the Initial Securities (including, without limitation, the Initial Purchasers), the Exchange Securities (as defined below) and the Private Exchange Securities (as defined below) (collectively the “Holders”), as follows:

1.  Registered Exchange Offer.  The Company shall, at its own cost, prepare and, not later than 180 days (or if the 180th day is not a business day, the first business day thereafter) after the date of original issue of the Initial Securities (the “Issue Date”), file with the Securities and Exchange Commission (the “Commission”) a registration statement (the “Exchange Offer Registration Statement”) on an appropriate form under the Securities Act of 1933, as amended (the “Securities Act”), with respect to a

proposed offer (the “Registered Exchange Offer”) to the Holders of Transfer Restricted Securities (as defined in Section 6(d) hereof), who are not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer, to issue and deliver to such Holders, in exchange for the Initial Securities, an equal aggregate principal amount of debt securities (the “Exchange Securities”) of the Issuer issued under the Indenture and identical in all material respects to the Initial Securities (except for the transfer restrictions relating to the Initial Securities and the provisions relating to the matters described in Section 6 hereof) that would be registered under the Securities Act.  The Company shall use its reasonable best efforts to cause such Exchange Offer Registration Statement to become effective under the Securities Act within 270 days (or if the 270th day is not a business day, the first business day thereafter) after the Issue Date and shall keep the Exchange Offer Registration Statement effective for not less than 30 days (or longer, if required by applicable law) after the date notice of the Registered Exchange Offer is mailed to the Holders (such period being called the “Exchange Offer Registration Period”).

If the Company effects the Registered Exchange Offer, the Company will be entitled to close the Registered Exchange Offer 30 days after the commencement thereof provided that the Company has accepted all the Initial Securities theretofore validly tendered in accordance with the terms of the Registered Exchange Offer.

As soon as practicable after the declaration of the effectiveness of the Exchange Offer Registration Statement, the Company shall commence the Registered Exchange Offer, it being the objective of such Registered Exchange Offer to enable each Holder of Transfer Restricted Securities (as defined in Section 6(d) hereof) electing to exchange the Initial Securities for Exchange Securities (assuming that such Holder is not an affiliate of the Company within the meaning of the Securities Act, acquires the Exchange Securities in the ordinary course of such Holder’s business and has no arrangements with any person to participate in the distribution of the Exchange Securities and is not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer) to trade such Exchange Securities from and after their receipt without any limitations or restrictions under the Securities Act and without material restrictions under the securities laws of the several states of the United States.

The Company acknowledges that, pursuant to current interpretations by the Commission’s staff of Section 5 of the Securities Act, in the absence of an applicable exemption therefrom, (i) each Holder which is a broker-dealer electing to exchange Initial Securities, acquired for its own account as a result of market making activities or other trading activities, for Exchange Securities (an “Exchanging Dealer”), is required to deliver a prospectus containing the information set forth in (a) Annex A hereto on the cover, (b) Annex B hereto in the “Exchange Offer Procedures” section and the “Purpose of the Exchange Offer” section, and (c) Annex C hereto in the “Plan of Distribution” section of such prospectus in connection with a sale of any such Exchange Securities received by such Exchanging Dealer pursuant to the Registered Exchange Offer and (ii) an Initial Purchaser that elects to sell Exchange Securities acquired in exchange for Initial Securities constituting any portion of an unsold allotment is required to deliver a prospectus containing the information required by Items 507 or 508 of Regulation S-K under the Securities Act, as applicable, in connection with such sale.

The Company shall use its reasonable best efforts to keep the Exchange Offer Registration Statement effective and to amend and supplement the prospectus contained therein, in order to permit such prospectus to be lawfully delivered by all persons subject to the prospectus delivery requirements of the Securities Act for such period of time as such persons must comply with such requirements in order to resell the Exchange Securities; provided, however, that (i) in the case where such prospectus and any amendment or supplement thereto must be delivered by an Exchanging Dealer or an Initial Purchaser, such period shall be the lesser of 180 days and the date on which all Exchanging Dealers and the Initial Purchasers have sold all Exchange Securities held by them (unless such period is extended pursuant to Section 3(j) below) and (ii) the Company shall make such prospectus and any amendment or supplement thereto, available to any broker-dealer for use in connection with any resale of any Exchange Securities for a period of not less than 180 days after the consummation of the Registered Exchange Offer.

If, upon consummation of the Registered Exchange Offer, any Initial Purchaser holds Initial Securities acquired by it as part of its initial distribution, the Company, simultaneously with the delivery of the Exchange Securities pursuant to the Registered Exchange Offer, shall issue and deliver to such Initial Purchaser upon the written request of such Initial Purchaser, in exchange (the “Private Exchange”) for the Initial Securities held by such Initial Purchaser, an equal principal amount of debt securities of the Company issued under the Indenture and identical in all material respects (including the existence of restrictions on transfer under the Securities Act and the securities laws of the several states of the United States, but excluding provisions relating to the matters described in Section 6 hereof) to the Initial Securities (the “Private Exchange Securities”).  The Initial Securities, the Exchange Securities and the Private Exchange Securities are herein collectively called the “Securities”.

In connection with the Registered Exchange Offer, the Company shall:

(a)  mail, or cause to be mailed, to each Holder a copy of the prospectus forming part of the Exchange Offer Registration Statement, together with an appropriate letter of transmittal and related documents;

(b)  keep the Registered Exchange Offer open for not less than 30 days (or longer, if required by applicable law) after the date notice thereof is mailed to the Holders;

(c)  utilize the services of a depositary for the Registered Exchange Offer with an address in the Borough of Manhattan, The City of New York, which may be the Trustee or an affiliate of the Trustee;

(d)  permit Holders to withdraw tendered Securities at any time prior to the close of business, New York time, on the last business day on which the Registered Exchange Offer shall remain open; and

(e)  otherwise comply in all material respects with all applicable laws.

As soon as practicable after the close of the Registered Exchange Offer or the Private Exchange, as the case may be, the Company shall:

(x)  accept for exchange all the Securities validly tendered and not withdrawn pursuant to the Registered Exchange Offer and the Private Exchange;

(y)  deliver to the Trustee for cancellation all the Initial Securities so accepted for exchange; and

(z)  cause the Trustee to authenticate and deliver promptly to each Holder of the Initial Securities, Exchange Securities or Private Exchange Securities, as the case may be, equal in principal amount to the Initial Securities of such Holder so accepted for exchange.

The Indenture provides that the Exchange Securities are not subject to the transfer restrictions set forth in the Indenture and that all the Securities vote and consent together on all matters as one class and that none of the Securities have the right to vote or consent as a class separate from one another on any matter.

Interest on each Exchange Security and Private Exchange Security issued pursuant to the Registered Exchange Offer and in the Private Exchange will accrue from the last interest payment date on which interest was paid on the Initial Securities surrendered in exchange therefor or, if no interest has been paid on the Initial Securities, from January 15, 2007.

3

Each Holder participating in the Registered Exchange Offer shall be required to represent to the Company that at the time of the consummation of the Registered Exchange Offer (i) any Exchange Securities received by such Holder will be acquired in the ordinary course of business, (ii) such Holder will have no arrangements or understanding with any person to participate in the distribution of the Securities or the Exchange Securities within the meaning of the Securities Act, (iii) such Holder is not an “affiliate,” as defined in Rule 405 of the Securities Act, of the Company or if it is an affiliate, such Holder will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable, (iv) if such Holder is not a broker-dealer, that it is not engaged in, and does not intend to engage in, the distribution of the Exchange Securities and (v) if such Holder is a broker-dealer, that it will receive Exchange Securities for its own account in exchange for Initial Securities that were acquired as a result of market-making activities or other trading activities and that it will be required to acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities.

Notwithstanding any other provisions hereof, the Company will ensure that (i) any Exchange Offer Registration Statement and any amendment thereto and any prospectus forming part thereof and any supplement thereto complies in all material respects with the Securities Act and the rules and regulations thereunder, (ii) any Exchange Offer Registration Statement and any amendment thereto does not, when it becomes effective, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading and (iii) any prospectus forming part of any Exchange Offer Registration Statement, and any supplement to such prospectus, does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

2.  Shelf Registration.  If, (i) because of any change in law or in applicable interpretations thereof by the staff of the Commission, the Company is not permitted to effect a Registered Exchange Offer, as contemplated by Section 1 hereof, (ii) the Registered Exchange Offer is not consummated within 310 days of the Issue Date, (iii) any Initial Purchaser so requests with respect to the Initial Securities (or the Private Exchange Securities) not eligible to be exchanged for Exchange Securities in the Registered Exchange Offer and held by it following consummation of the Registered Exchange Offer or (iv) any Holder (other than an Exchanging Dealer) is not eligible to participate in the Registered Exchange Offer or, in the case of any Holder (other than an Exchanging Dealer) that participates in the Registered Exchange Offer, such Holder does not receive freely tradeable Exchange Securities on the date of the exchange and any such Holder so requests, the Company shall take the following actions:

(a)  The Company shall, at its cost, as promptly as practicable (but in no event more than 60 days after so required or requested pursuant to this Section 2) file with the Commission and thereafter shall use its reasonable best efforts to cause to be declared effective (unless it becomes effective automatically upon filing) a registration statement (the “Shelf Registration Statement” and, together with the Exchange Offer Registration Statement, a “Registration Statement”) on an appropriate form under the Securities Act relating to the offer and sale of the Transfer Restricted Securities (as defined in Section 6(d) hereof) by the Holders thereof from time to time in accordance with the methods of distribution set forth in the Shelf Registration Statement and Rule 415 under the Securities Act (hereinafter, the “Shelf Registration”), it being agreed that in the case the Company is filing a Shelf Registration Statement due to (x) the occurrence of the events specified in clause (i) of this Section 2, the Company shall use its reasonable best efforts to have such Shelf Registration Statement declared effective on or prior to the 270th day after the Issue Date or (y) the occurrence of the events specified in clause (ii), (iii) or (iv) of this Section 2, the Company shall use its reasonable best efforts to have such Shelf Registration Statement declared effective on or prior to the 60th day after the date on which the Shelf Registration Statement is required to be filed; provided, however, that no Holder (other than an Initial Purchaser) shall be entitled to have the Securities held by it covered by such Shelf Registration Statement unless such Holder agrees in writing to be bound by all the provisions of this Agreement applicable to such Holder.

4

(b)  The Company shall use its reasonable best efforts to keep the Shelf Registration Statement continuously effective in order to permit the prospectus included therein to be lawfully delivered by the Holders of the relevant Securities, for a period of two years (or for such longer period if extended pursuant to Section 3(j) below) from the Issue Date or such shorter period that will terminate when all the Securities covered by the Shelf Registration Statement (i) have been sold pursuant thereto or (ii) are no longer restricted securities (as defined in Rule 144 under the Securities Act, or any successor rule thereof).  The Company shall be deemed not to have used its reasonable best efforts to keep the Shelf Registration Statement effective during the requisite period if it voluntarily takes any action that would result in Holders of Securities covered thereby not being able to offer and sell such Securities during that period, unless such action is required by applicable law.

(c)  Notwithstanding any other provisions of this Agreement to the contrary, the Company shall cause the Shelf Registration Statement and the related prospectus and any amendment or supplement thereto, as of the effective date of the Shelf Registration Statement, amendment or supplement, (i) to comply in all material respects with the applicable requirements of the Securities Act and the rules and regulations of the Commission and (ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

3.  Registration Procedures.  In connection with any Shelf Registration contemplated by Section 2 hereof and, to the extent applicable, any Registered Exchange Offer contemplated by Section 1 hereof, the following provisions shall apply:

(a)  The Company shall (i) furnish to each Initial Purchaser, prior to the filing thereof with the Commission, a copy of the Registration Statement and each amendment thereof and each supplement, if any, to the prospectus included therein and, in the event that an Initial Purchaser (with respect to any portion of an unsold allotment from the original offering) is participating in the Registered Exchange Offer or the Shelf Registration Statement, the Company shall use its best efforts to reflect in each such document, when so filed with the Commission, such comments as such Initial Purchaser reasonably may propose; (ii) include the information set forth in Annex A hereto on the cover, in Annex B hereto in the “Exchange Offer Procedures” section and the “Purpose of the Exchange Offer” section and in Annex C hereto in the “Plan of Distribution” section of the prospectus forming a part of the Exchange Offer Registration Statement and include the information set forth in Annex D hereto in the Letter of Transmittal delivered pursuant to the Registered Exchange Offer; (iii) if requested by an Initial Purchaser, include the information required by Items 507 or 508 of Regulation S-K under the Securities Act, as applicable, in the prospectus forming a part of the Exchange Offer Registration Statement; (iv) include within the prospectus contained in the Exchange Offer Registration Statement a section entitled “Plan of Distribution,” reasonably acceptable to the Initial Purchasers, which shall contain a summary statement of the positions taken or policies made by the staff of the Commission with respect to the potential “underwriter” status of any broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of Exchange Securities received by such broker-dealer in the Registered Exchange Offer (a “Participating Broker-Dealer”), whether such positions or policies have been publicly disseminated by the staff of the Commission or such positions or policies, in the reasonable judgment of the Initial Purchasers based upon advice of counsel (which may be in-house counsel), represent the prevailing views of the staff of the Commission; and (v) in the case of a Shelf Registration Statement, include in the prospectus included in the Shelf Registration Statement (or, if permitted by Commission Rule 430B(b), in a prospectus supplement that becomes a part thereof pursuant to Commission Rule 430B(f)) that is delivered to any Holder pursuant to Section 3(d)

5

and (f), the names of the Holders, who propose to sell Securities pursuant to the Shelf Registration Statement, as selling securityholders.

(b)  The Company shall give written notice to the Initial Purchasers, the Holders of the Securities and any Participating Broker-Dealer from whom the Company has received prior written notice that it will be a Participating Broker-Dealer in the Registered Exchange Offer (which notice pursuant to clauses (ii)-(v) hereof shall be accompanied by an instruction to suspend the use of the prospectus until the requisite changes have been made):

(i)  when the Registration Statement or any amendment thereto has been filed with the Commission and when the Registration Statement or any post-effective amendment thereto has become effective;

(ii)  of any request by the Commission for amendments or supplements to the Registration Statement or the prospectus included therein or for additional information;

(iii)  of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose, of the issuance by the Commission of a notification of objection to the use of the form on which the Registration Statement has been filed, and of the happening of any event that causes the Company to become an “ineligible issuer,” as defined in Commission Rule 405.

(iv)  of the receipt by the Company or its legal counsel of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(v)  of the happening of any event that requires the Company to make changes in the Registration Statement or the prospectus in order that the Registration Statement or the prospectus do not contain an untrue statement of a material fact nor omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the prospectus, in light of the circumstances under which they were made) not misleading.

(c)  The Company shall make every reasonable effort to obtain the withdrawal at the earliest possible time, of any order suspending the effectiveness of the Registration Statement.

(d)  The Company shall furnish to each Holder of Securities included within the coverage of the Shelf Registration, without charge, at least one copy of the Shelf Registration Statement and any post-effective amendment or supplement thereto, including financial statements and schedules, and, if the Holder so requests in writing, all exhibits thereto (including those, if any, incorporated by reference).  The Company shall not, without the prior consent of the Initial Purchasers, make any offer relating to the Securities that would constitute a “free writing prospectus,” as defined in Commission Rule 405.

(e)  The Company shall deliver to each Exchanging Dealer and each Initial Purchaser, and to any other Holder who so requests in writing, without charge, at least one copy of the Exchange Offer Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if any Initial Purchaser or any such Holder so requests, all exhibits thereto (including those incorporated by reference).

(f)  The Company shall, during the period of effectiveness of the Shelf Registration Statement, deliver to each Holder of Securities included within the coverage of the Shelf Registration, without charge, as many copies of the prospectus (including each preliminary

6

prospectus) included in the Shelf Registration Statement and any amendment or supplement thereto as such person may reasonably request in writing. The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by each of the selling Holders of the Securities in connection with the offering and sale of the Securities covered by the prospectus, or any amendment or supplement thereto, included in the Shelf Registration Statement.

(g)  The Company shall deliver to each Initial Purchaser, any Exchanging Dealer, any Participating Broker-Dealer and such other persons required to deliver a prospectus following the Registered Exchange Offer, without charge, as many copies of the final prospectus included in the Exchange Offer Registration Statement and any amendment or supplement thereto as such persons may reasonably request.  The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by any Initial Purchaser, if necessary, any Participating Broker-Dealer and such other persons required to deliver a prospectus following the Registered Exchange Offer in connection with the offering and sale of the Exchange Securities covered by the prospectus, or any amendment or supplement thereto, included in such Exchange Offer Registration Statement.

(h)  Prior to any public offering of the Securities pursuant to any Registration Statement, the Company shall register or qualify or cooperate with the Holders of the Securities included therein and their respective counsel in connection with the registration or qualification of the Securities for offer and sale under the securities or “blue sky” laws of such states of the United States as any Holder of the Securities reasonably requests in writing and do any and all other acts or things reasonably necessary or advisable to enable the offer and sale in such jurisdictions of the Securities covered by such Registration Statement; provided, however, that the Company shall not be required to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified as of the date hereof or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise subject as of the date hereof.

(i)  The Company shall cooperate with the Holders of the Securities to facilitate the timely preparation and delivery of certificates representing the Securities to be sold pursuant to any Registration Statement free of any restrictive legends and in such denominations and registered in such names as the Holders may request a reasonable period of time prior to sales of the Securities pursuant to such Registration Statement.

(j)  Upon the occurrence of any event contemplated by paragraphs (ii) through (v) of Section 3(b) above during the period for which the Company is required to maintain an effective Registration Statement, the Company shall promptly prepare and file a post-effective amendment to the Registration Statement or a supplement to the related prospectus and any other required document so that, as thereafter delivered to Holders of the Securities or purchasers of Securities, the prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.  If the Company notifies the Initial Purchasers, the Holders of the Securities and any known Participating Broker-Dealer in accordance with paragraphs (ii) through (v) of Section 3(b) above to suspend the use of the prospectus until the requisite changes to the prospectus have been made, then the Initial Purchasers, the Holders of the Securities and any such Participating Broker-Dealers shall suspend use of such prospectus, and the period of effectiveness of the Shelf Registration Statement provided for in Section 2(b) above and the Exchange Offer Registration Statement provided for in Section 1 above shall each be extended by the number of days from and including the date of the giving of such notice to and including the date when the Initial Purchasers, the Holders of the Securities and any known Participating Broker-Dealer shall have received such amended or supplemented prospectus pursuant to this Section 3(j).  During the period during which the

7

Company is required to maintain an effective Shelf Registration Statement pursuant to this Agreement, the Company will prior to the three-year expiration of that Shelf Registration Statement file, and use its reasonable best efforts to cause to be declared effective (unless it becomes effective automatically upon filing) within a period that avoids any interruption in the ability of Holders of Securities covered by the expiring Shelf Registration Statement to make registered dispositions, a new registration statement relating to the Securities, which shall be deemed the “Shelf Registration Statement” for purposes of this Agreement.

(k)  Not later than the effective date of the applicable Registration Statement, the Company will provide a CUSIP number for the Initial Securities, the Exchange Securities or the Private Exchange Securities, as the case may be, and provide the applicable trustee with printed certificates for the Initial Securities, the Exchange Securities or the Private Exchange Securities, as the case may be, in a form eligible for deposit with The Depository Trust Company.

(l)  The Company will comply in all material respects with all rules and regulations of the Commission to the extent and so long as they are applicable to the Registered Exchange Offer or the Shelf Registration and will make generally available to its security holders (or otherwise provide in accordance with Section 11(a) of the Securities Act) an earning statement satisfying the provisions of Section 11(a) of the Securities Act, no later than 45 days after the end of a 12-month period (or 90 days, if such period is a fiscal year) beginning with the first month of the Company’s first fiscal quarter commencing after the effective date of the Registration Statement, which statement shall cover such 12-month period.

(m)  The Company shall cause the Indenture to be qualified under the Trust Indenture Act of 1939, as amended, in a timely manner and containing such changes, if any, as shall be necessary for such qualification.  In the event that such qualification would require the appointment of a new trustee under the Indenture, the Company shall appoint a new trustee thereunder pursuant to the applicable provisions of the Indenture.

(n)  The Company may require each Holder of Securities to be sold pursuant to the Shelf Registration Statement to furnish to the Company such information regarding the Holder and the distribution of the Securities as the Company may from time to time reasonably require for inclusion in the Shelf Registration Statement, and the Company may exclude from such registration the Securities of any Holder that unreasonably fails to furnish such information within a reasonable time after receiving such request.

(o)  The Company shall enter into such customary agreements (including, if requested, an underwriting agreement in customary form) and take all such other action, if any, as any Holder of the Securities shall reasonably request in order to facilitate the disposition of the Securities pursuant to any Shelf Registration.

(p)  In the case of any Shelf Registration, the Company shall (i) make reasonably available for inspection by the Holders of the Securities, any underwriter participating in any disposition pursuant to the Shelf Registration Statement and any attorney, accountant or other agent retained by the Holders of the Securities or any such underwriter all relevant financial and other records, pertinent corporate documents and properties of the Company and (ii) cause the Company’s officers, directors, employees, accountants and auditors to supply all relevant information reasonably requested by the Holders of the Securities or any such underwriter, attorney, accountant or agent in connection with the Shelf Registration Statement, in each case, as shall be reasonably necessary to enable such persons, to conduct a reasonable investigation within the meaning of Section 11 of the Securities Act; provided, however, that the foregoing inspection and information gathering shall be coordinated on behalf of the Initial Purchasers by you and on behalf of the other parties, by one counsel designated by and on behalf of such other parties as described in Section 4 hereof.

8

(q)  In the case of any Shelf Registration, the Company, if requested by any Holder of Securities covered thereby, shall cause (i) its counsel to deliver an opinion and updates thereof relating to the Securities in customary form addressed to such Holders and the managing underwriters, if any, thereof and dated, in the case of the initial opinion, the effective date of such Shelf Registration Statement (it being agreed that the matters to be covered by such opinion shall include, without limitation, the due incorporation and good standing of the Company; the qualification of the Company to transact business as foreign corporations; the due authorization, execution and delivery of the relevant agreement of the type referred to in Section 3(o) hereof; the due authorization, execution, authentication and issuance, and the validity and enforceability, of the applicable Securities; the absence of material legal or governmental proceedings involving the Company; the absence of governmental approvals required to be obtained in connection with the Shelf Registration Statement, the offering and sale of the applicable Securities, or any agreement of the type referred to in Section 3(o) hereof; the compliance in all material respects, as to form of such Shelf Registration Statement and any documents incorporated by reference therein and of the Indenture with the requirements of the Securities Act and the Trust Indenture Act, respectively; and (A) as of the date of the opinion and as of the effective date of the Shelf Registration Statement or most recent post-effective amendment thereto, as the case may be, the absence, to the knowledge of such counsel, from such Shelf Registration Statement and the prospectus included therein, as then amended or supplemented, and from any documents incorporated by reference therein and (B) as of an applicable time identified by such Holders or managing underwriters, the absence, to the knowledge of such counsel, from such prospectus taken together with any other documents identified by such Holders or managing underwriters, in the case of (A) and (B), of an untrue statement of a material fact or the omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any such documents, in the light of the circumstances existing at the time that such documents were filed with the Commission under the Exchange Act); (ii) its officers to execute and deliver all customary documents and certificates and updates thereof reasonably requested by any underwriters of the applicable Securities and (iii) its independent public accountants and the independent public accountants with respect to any other entity for which financial information is provided in the Shelf Registration Statement to provide to the selling Holders of the applicable Securities and any underwriter therefor a comfort letter in customary form and covering matters of the type customarily covered in comfort letters in connection with primary underwritten offerings, subject to receipt of appropriate documentation as contemplated, and only if permitted, by Statement of Auditing Standards No. 72.

(r)  In the case of the Registered Exchange Offer, if requested by any Initial Purchaser or any known Participating Broker-Dealer, the Company shall cause (i) its counsel to deliver to such Initial Purchaser or such Participating Broker-Dealer a signed opinion in the form set forth in Section 7(e) of the Purchase Agreement with such changes as are customary in connection with the preparation of a Registration Statement and (ii) its independent public accountants and the independent public accountants with respect to any other entity for which financial information is provided in the Registration Statement to deliver to such Initial Purchaser or such Participating Broker-Dealer a comfort letter, in customary form, meeting the requirements as to the substance thereof as set forth in Section 7(a) and (b) of the Purchase Agreement, with appropriate date changes.

(s)  If a Registered Exchange Offer or a Private Exchange is to be consummated, upon delivery of the Initial Securities by Holders to the Company (or to such other Person as directed by the Company) in exchange for the Exchange Securities or the Private Exchange Securities, as the case may be, the Company shall mark, or caused to be marked, on the Initial Securities so exchanged that such Initial Securities are being canceled in exchange for the Exchange Securities or the Private Exchange Securities, as the case may be; in no event shall the Initial Securities be marked as paid or otherwise satisfied.

9

(t)  The Company will use its reasonable best efforts to (a) if the Initial Securities have been rated prior to the initial sale of such Initial Securities, confirm such ratings will apply to the Securities covered by a Registration Statement, or (b) if the Initial Securities were not previously rated, cause the Securities covered by a Registration Statement to be rated with the appropriate rating agencies, if so requested by Holders of a majority in aggregate principal amount of Securities covered by such Registration Statement, or by the managing underwriters, if any.

(u)  In the event that any broker-dealer registered under the Exchange Act shall underwrite any Securities or participate as a member of an underwriting syndicate or selling group or “assist in the distribution” (within the meaning of the Conduct Rules (the “Rules”) of the National Association of Securities Dealers, Inc. (“NASD”)) thereof, whether as a Holder of such Securities or as an underwriter, a placement or sales agent or a broker or dealer in respect thereof, or otherwise, the Company will assist such broker-dealer in complying with the requirements of such Rules, including, without limitation, by (i) if such Rules, including Rule 2720, shall so require, engaging a “qualified independent underwriter” (as defined in Rule 2720) to participate in the preparation of the Registration Statement relating to such Securities, to exercise usual standards of due diligence in respect thereto and, if any portion of the offering contemplated by such Registration Statement is an underwritten offering or is made through a placement or sales agent, to recommend the yield of such Securities, (ii) indemnifying any such qualified independent underwriter to the extent of the indemnification of underwriters provided in Section 5 hereof and (iii) providing such information to such broker-dealer as may be required in order for such broker-dealer to comply with the requirements of the Rules.

(v)  The Company shall use its reasonable best efforts to take all other steps necessary to effect the registration of the Securities covered by a Registration Statement contemplated hereby.

4.  Registration Expenses.  The Company shall bear all fees and expenses incurred by it in connection with the performance of its obligations under Sections 1 through 3 hereof and shall also pay the reasonable fees and expenses, if any, of Cravath, Swaine & Moore LLP, counsel for the Initial Purchasers, incurred in connection with the Registered Exchange Offer, whether or not the Registered Exchange Offer is filed or becomes effective, and, in the event a Shelf Registration Statement is required to be filed hereunder, shall bear or reimburse the Holders of the Securities covered thereby for the reasonable fees and disbursements of one firm of counsel designated by the Holders of a majority in principal amount of the Initial Securities covered thereby to act as counsel for the Holders of the Initial Securities in connection therewith.

5.  Indemnification.  (a)  The Company agrees to indemnify and hold harmless each Holder of the Securities, any Participating Broker-Dealer and each person, if any, who controls such Holder or such Participating Broker-Dealer within the meaning of the Securities Act or the Exchange Act (each Holder, any Participating Broker-Dealer and such controlling persons are referred to collectively as the “Indemnified Parties”) from and against any losses, claims, damages or liabilities, joint or several, or any actions in respect thereof (including, but not limited to, any losses, claims, damages, liabilities or actions relating to purchases and sales of the Securities) to which each Indemnified Party may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus or “issuer free writing prospectus,” as defined in Commission Rule 433 (“Issuer FWP”), relating to a Shelf Registration, or arise out of, or are based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse, as incurred, the Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action in respect thereof; provided, however, that (i) the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon any untrue

10

statement or alleged untrue statement or omission or alleged omission made in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus or Issuer FWP relating to a Shelf Registration in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein and (ii) with respect to any untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus relating to a Shelf Registration Statement, the indemnity agreement contained in this subsection (a) shall not inure to the benefit of any Holder or Participating Broker-Dealer from whom the person asserting any such losses, claims, damages or liabilities purchased the Securities concerned, to the extent that a prospectus relating to such Securities was required to be delivered (including through satisfaction of the conditions of Commission Rule 172) by such Holder or Participating Broker-Dealer under the Securities Act in connection with such purchase and any such loss, claim, damage or liability of such Holder or Participating Broker-Dealer results from the fact that there was not conveyed to such person, at or prior to the time of the sale of such Securities to such person, an amended or supplemented prospectus or, if permitted by Section 3(d), an Issuer FWP correcting such untrue statement or omission or alleged untrue statement or omission if the Company had previously furnished copies thereof to such Holder or Participating Broker-Dealer; provided further, however, that this indemnity agreement will be in addition to any liability which the Company may otherwise have to such Indemnified Party.  The Company shall also indemnify underwriters, their officers and directors and each person who controls such underwriters within the meaning of the Securities Act or the Exchange Act to the same extent as provided above with respect to the indemnification of the Holders of the Securities if requested by such Holders.

(b)  Each Holder of the Securities, severally and not jointly, will indemnify and hold harmless the Company and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act from and against any losses, claims, damages or liabilities or any actions in respect thereof, to which the Company or any such controlling person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus or Issuer FWP relating to a Shelf Registration, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or omission or alleged untrue statement or omission was made in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein; and, subject to the limitation set forth immediately preceding this clause, shall reimburse, as incurred, the Company for any legal or other expenses reasonably incurred by the Company or any such controlling person in connection with investigating or defending any loss, claim, damage, liability or action in respect thereof.  This indemnity agreement will be in addition to any liability which such Holder may otherwise have to the Company or any of its controlling persons.

(c)  Promptly after receipt by an Indemnified Party under this Section 5 of notice of the commencement of any action or proceeding (including a governmental investigation), such Indemnified Party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 5, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an Indemnified Party otherwise than under subsection  (a) or (b) above.  In case any such action is brought against any Indemnified Party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Party (who shall not, except with the consent of the Indemnified Party, be counsel to the indemnifying party), and after notice from the indemnifying party to such Indemnified Party of its election so to assume the defense thereof the indemnifying party will not be liable to such Indemnified Party under this Section 5 for any legal or other

expenses, other than reasonable costs of investigation, subsequently incurred by such Indemnified Party in connection with the defense thereof.  No indemnifying party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending or threatened action in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party unless such settlement (i) includes an unconditional release of such Indemnified Party from all liability on any claims that are the subject matter of such action, and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any Indemnified Party.

(d)  If the indemnification provided for in this Section 5 is unavailable or insufficient to hold harmless an Indemnified Party under subsections (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such Indemnified Party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the Indemnified Party on the other from the exchange of the Securities, pursuant to the Registered Exchange Offer, or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the indemnifying party or parties on the one hand and the Indemnified Party on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof) as well as any other relevant equitable considerations.  The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or such Holder or such other Indemnified Party, as the case may be, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  The amount paid by an Indemnified Party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any action or claim which is the subject of this subsection (d).  Notwithstanding any other provision of this Section 5(d), the Holders of the Securities shall not be required to contribute any amount in excess of the amount by which the net proceeds received by such Holders from the sale of the Securities pursuant to a Registration Statement exceeds the amount of damages which such Holders have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  For purposes of this paragraph (d), each person, if any, who controls such Indemnified Party within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as such Indemnified Party and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as the Company.

(e)  The agreements contained in this Section 5 shall survive the sale of the Securities pursuant to a Registration Statement and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any Indemnified Party.

6.  Additional Interest Under Certain Circumstances.  (a)  Additional interest (the “Additional Interest”) with respect to the Initial Securities shall be assessed as follows if any of the following events occur (each such event in clauses (i) through (v) below a “Registration Default”:

(i)  If on or prior to August 6, 2007, the Exchange Offer Registration Statement has not been filed with the Commission;

(ii)  If the Company is required to file a Shelf Registration Statement pursuant to the terms of Section 2(a) above, the Shelf Registration Statement has not been filed with the

12

Commission on or prior to the 60th day after the date on which the obligation to file such Shelf Registration Statement arises, determined in accordance with the terms of Section 2(a) above;

(iii)  If on or prior to November 5, 2007, neither the Registered Exchange Offer nor, if required in lieu thereof, the Shelf Registration Statement, is declared effective by the Commission;

(iv)  if the Exchange Offer is not consummated on or before the 40th day after the Exchange Offer Registration Statement is declared effective or, if obligated to file a Shelf Registration Statement pursuant to the terms of Section 2(a) above, the Shelf Registration Statement is not declared effective on or prior to the 60th day after the date of the filing of the Shelf Registration Statement; or

(v)  If after either the Exchange Offer Registration Statement or the Shelf Registration Statement is declared (or becomes automatically) effective (A) such Registration Statement thereafter ceases to be effective; or (B) such Registration Statement or the related prospectus ceases to be usable (except as permitted in paragraph (b) immediately below) in connection with resales of Transfer Restricted Securities during the periods specified herein because either (1) any event occurs as a result of which the related prospectus forming part of such Registration Statement would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, (2) it shall be necessary to amend such Registration Statement or supplement the related prospectus, to comply with the Securities Act or the Exchange Act or the respective rules thereunder, or (3) such Registration Statement is a Shelf Registration Statement that has expired before a replacement Shelf Registration Statement has become effective.

Additional Interest shall accrue on the Initial Securities over and above the interest set forth in the title of the Securities from and including the date on which any such Registration Default shall occur to but excluding the date on which all such Registration Defaults have been cured, at a rate of $0.05 per week per $1,000 principal amount of the Initial Securities for the first 90-day period immediately following the occurrence of a Registration Default, and such rate will increase by an additional $0.05 per week per $1,000 principal amount of the Initial Securities with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum additional interest rate of 1.0% per annum.

(b)  A Registration Default referred to in Section 6(a)(v)(B) hereof shall be deemed not to have occurred and be continuing in relation to a Shelf Registration Statement or the related prospectus if (i) such Registration Default has occurred solely as a result of (x) the filing of a post-effective amendment to such Shelf Registration Statement to incorporate annual audited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared effective to permit Holders to use the related prospectus or (y) other material events with respect to the Company that would need to be described in such Shelf Registration Statement or the related prospectus and (ii) in the case of clause (y), the Company is proceeding promptly and in good faith to amend or supplement such Shelf Registration Statement and related prospectus to describe such material events; provided, however, that in any case if such Registration Default occurs for a continuous period in excess of 30 days, Additional Interest shall be payable in accordance with the above paragraph from the day such Registration Default occurs until such Registration Default is cured.

(c)  Any amounts of Additional Interest due pursuant to clause (i), (ii), (iii), (iv) or (v) of Section 6(a) above will be payable in cash on the regular interest payment dates with respect to the Initial Securities. The amount of Additional Interest will be determined on the basis of the number of days that Additional Interest is payable hereunder and on the basis of a 360-day year comprised of twelve 30-day months.

(d)  “Transfer Restricted Securities” means each Security until (i) the date on which such Transfer Restricted Security has been exchanged by a person other than a broker-dealer for a freely transferable

13

Exchange Security in the Registered Exchange Offer, (ii) following the exchange by a broker-dealer in the Registered Exchange Offer of an Initial Security for an Exchange Security, the date on which such Exchange Security is sold to a purchaser who receives from such broker-dealer on or prior to the date of such sale a copy of the prospectus contained in the Exchange Offer Registration Statement, (iii) the date on which such Transfer Restricted Security has been effectively registered under the Securities Act and disposed of in accordance with the Shelf Registration Statement or (iv) the date on which such Transfer Restricted Security is distributed to the public pursuant to Rule 144 under the Securities Act or is saleable pursuant to Rule 144(k) under the Securities Act.

7.  Rules 144 and 144A.  So long as it is required to do so by the Indenture, the Company shall use its reasonable best efforts to file the reports required to be filed by it under the Securities Act and the Exchange Act in a timely manner and, if at any time the Company is not required to file such reports, it will, upon the request of any Holder of Initial Securities, make publicly available other information so long as necessary to permit sales of their securities pursuant to Rules 144 and 144A.  The Company covenants that it will take such further action as any Holder of Initial Securities may reasonably request, all to the extent required from time to time to enable such Holder to sell Initial Securities without registration under the Securities Act within the limitation of the exemptions provided by Rules 144 and 144A (including the requirements of Rule 144A(d)(4)).  The Company will provide a copy of this Agreement to prospective purchasers of Initial Securities identified to the Company by the Initial Purchasers upon written request.  Upon the written request of any Holder of Initial Securities, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the Company to register any of its securities pursuant to the Exchange Act.

8.  Underwritten Registrations.  If any of the Transfer Restricted Securities covered by any Shelf Registration are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will administer the offering (“Managing Underwriters”) will be selected by the Holders of a majority in aggregate principal amount of such Transfer Restricted Securities to be included in such offering.

No person may participate in any underwritten registration hereunder unless such person (i) agrees to sell such person’s Transfer Restricted Securities on the basis reasonably provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.

9.  Miscellaneous.

(a)  Amendments and Waivers.  The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, except by the Company and the written consent of the Holders of a majority in principal amount of the Securities affected by such amendment, modification, supplement, waiver or consents.

(b)  Notices.  All notices and other communications provided for or permitted hereunder shall be made in writing by hand delivery, first-class mail, facsimile transmission, or air courier which guarantees overnight delivery:

ANNEX A

Each broker-dealer that receives Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities.  The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.  This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Initial Securities where such Initial Securities were acquired by such broker-dealer as a result of market-making activities or other trading activities.  The Company has agreed that, for a period of 180 days after the Expiration Date (as defined herein), it will make this Prospectus available to any broker-dealer for use in connection with any such resale.  See “Plan of Distribution.”

ANNEX B

Each broker-dealer that receives Exchange Securities for its own account in exchange for Initial Securities, where such Initial Securities were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities.  See “Plan of Distribution.”

ANNEX C

PLAN OF DISTRIBUTION

Each broker-dealer that receives Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a Prospectus in connection with any resale of such Exchange Securities.  This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Initial Securities where such Initial Securities were acquired as a result of market-making activities or other trading activities.  The Company has agreed that, for a period of 180 days after the Expiration Date, it will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale.  In addition, until [     ], 20[  ], all dealers effecting transactions in the Exchange Securities may be required to deliver a prospectus.(1)

(1) In addition, the legend required by Item 502(e) of Regulation S-K will appear on the back cover page of the Exchange Offer prospectus.

The Company will not receive any proceeds from any sale of Exchange Securities by broker-dealers.  Exchange Securities received by broker-dealers for their own account pursuant to the Exchange Offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the Exchange Securities or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices.  Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any such Exchange Securities.  Any broker-dealer that resells Exchange Securities that were received by it for its own account pursuant to the Exchange Offer and any broker or dealer that participates in a distribution of such Exchange Securities may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit on any such resale of Exchange Securities and any commission or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act.  The Letter of Transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

For a period of 180 days after the Expiration Date the Company will promptly send additional copies of this Prospectus and any amendment or supplement to this Prospectus to any broker-dealer that requests such documents in the Letter of Transmittal.  The Company has agreed to pay all of its expenses incident to the Exchange Offer and the reasonable expenses of one counsel for the Holders of the Securities other than commissions or concessions of any brokers or dealers and will indemnify the Holders of the Securities (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

Exhibit 10.3

AMENDMENT NO. 1, CONSENT AND AGREEMENT dated as of January 25, 2007 (this “Amendment”), to the Credit Agreement dated as of June 23, 2006 (the “Credit Agreement”), among TRANSDIGM INC. (the “Borrower”), TRANSDIGM GROUP INCORPORATED (“Holdings”), each subsidiary of the Borrower from time to time party thereto, the Lenders (as defined therein) and CREDIT SUISSE, as administrative agent and collateral agent (in such capacities, the “Agent”) for the Lenders.

A.            Pursuant to the Credit Agreement, the Lenders have extended, and have agreed to extend, credit to the Borrower.

B.            The Borrower has requested that (i) one or more Persons (including one or more existing Lenders) (all such Persons, “Additional Term Lenders”) make term loans (the “Additional Term Loans”) to the Borrower in an aggregate principal amount of $130,000,000 and (ii) one or more Persons (including one or more existing Lenders) (all such Persons, “Increasing Revolving Credit Lenders”) agree to provide additional Revolving Credit Commitments in an aggregate amount of $50,000,000, in each case on the Acquisition Closing Date (as defined below) and subject to the terms and conditions set forth herein.

C.            The Borrower has further requested certain amendments to the Credit Agreement as set forth herein.

D.            The proceeds of the Additional Term Loans will be used by the Borrower on the Acquisition Closing Date, together with the proceeds of the issuance by the Borrower of $300,000,000 in aggregate principal amount of senior subordinated notes (the “Senior Subordinated Notes”) and cash on hand, to pay the purchase price for the acquisition (the “Acquisition”) of Aviation Technologies, Inc. (the “Company”) and related transaction costs (including the payment of fees and expenses in connection with the Acquisition and this Amendment).

E.             The Requisite Lenders (as defined below) are willing to agree to such amendments on the terms and subject to the conditions set forth herein.

F.             The Additional Term Loan Commitments and the additional Revolving Credit Commitments will not constitute Incremental Term Loan Commitments or Incremental Revolving Credit Commitments, respectively.  The Incremental Term Loan Commitments and Incremental Revolving Credit Commitments will not be reduced as a result of this Amendment or the transactions contemplated hereby.

G.            Capitalized terms used but not defined herein shall have the meanings assigned to them in the Credit Agreement.

Accordingly, in consideration of the mutual agreements herein contained and other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, the parties hereto agree as follows:

SECTION 1.  Additional Term Loans and Additional Revolving Credit Commitments.  (a)  Subject to the terms and conditions set forth herein and relying upon the representations and warranties set forth herein and in the other Loan Documents, each Additional Term Lender, effective upon (i) the Acquisition Closing Date and (ii) such Additional Term Lender entering into an Assumption Agreement substantially in the form attached hereto as Exhibit A (or such other form as shall be acceptable to the Borrower, the Agent and such Additional Term Lender) (an “Assumption Agreement”), hereby agrees, severally and not jointly, to make an Additional Term Loan to the Borrower on the Acquisition Closing Date in a principal amount not to exceed the commitment (the “Additional Term Loan Commitment”) of such Additional Term Lender to make Additional Term Loans as set forth in the related Assumption Agreement (or in the Assignment and Acceptance pursuant to which such Additional Term Lender assumed its Additional Term Loan Commitment).

(b)  The Borrower will use the proceeds of the Additional Term Loans only for the purposes specified in the recitals to this Amendment.

(c)  Unless the context shall otherwise require, the term “Term Loans” as used in the Credit Agreement shall include the Additional Term Loans, the term “Term Loan Commitment” shall include the Additional Term Loan Commitments and the terms “Lenders” and “Term Lenders” shall include each Additional Term Lender.  For purposes of determining the initial interest rate on the Additional Term Loans when made, the Additional Term Loans of each Additional Term Lender shall be allocated ratably to each outstanding Term Borrowing and shall bear interest at the same rate as the outstanding Term Borrowing to which such Additional Term Loans are allocated for the remainder of the then current Interest Period, notwithstanding any provision to the contrary contained in the Credit Agreement.

(d)  Each Increasing Revolving Credit Lender, effective upon (i) the Acquisition Closing Date and (ii) such Increasing Revolving Credit Lender entering into an Assumption Agreement, hereby agrees that (x) in respect of each Increasing Revolving Credit Lender that is a Revolving Credit Lender immediately prior to the effective date specified in the related Assumption Agreement (the “Increase Effective Date”), such Increasing Revolving Credit Lender’s Revolving Credit Commitment in effect immediately prior to the Increase Effective Date shall be increased by the amount specified for such Increasing Revolving Credit Lender in the related Assumption Agreement, and (y) in respect of each Increasing Revolving Credit Lender that is not a Revolving Credit Lender immediately prior to the Increase Effective Date, such Increasing Revolving Credit Lender’s Revolving Credit Commitment shall be the amount specified for such Increasing Revolving Credit Lender in the related Assumption Agreement (in each case, as the same may change after the date thereof by assignments by or to such Lender in accordance with Section 9.04 of the Credit Agreement).  All such additional Revolving Credit Commitments shall constitute “Revolving Credit Commitments” and all Increasing Revolving Credit Lenders shall constitute “Revolving Credit Lenders” and “Lenders”, in each case for all purposes of the Credit Agreement and the other Loan Documents.

2

(e)  In order to effectuate the increase in Revolving Credit Commitments contemplated hereby, each of the parties hereto hereby agrees that the Agent may take any and all actions as may be reasonably necessary to ensure that, after giving effect to any such increase in Revolving Credit Commitments, the outstanding Revolving Loans (if any) are held by the Revolving Credit Lenders in accordance with their new applicable Pro Rata Percentages.  This may be accomplished at the discretion of the Agent, following consultation with the Borrower, (i) by requiring the outstanding Revolving Loans to be prepaid with the proceeds of a new Revolving Credit Borrowing to be made on any Increase Effective Date, (ii) by causing non-Increasing Revolving Credit Lenders to assign portions of their outstanding Revolving Loans to Increasing Revolving Credit Lenders or (iii) by any combination of the foregoing.  Any prepayment or assignment described in this paragraph (e) shall be subject to Section 2.14 of the Credit Agreement, but shall otherwise be without premium or penalty.

SECTION 2.  Amendments. (a)  As of the Acquisition Closing Date, the definition of the term “Incremental Revolving Credit Amount” set forth in Section 1.01 of the Credit Agreement is hereby amended by replacing the reference to “$250,000,000” with a reference to “$300,000,000”.

(b)  As of the Acquisition Closing Date, the definition of the term “Incremental Term Loan Amount” set forth in Section 1.01 of the Credit Agreement is hereby amended by replacing the reference to “$250,000,000” with a reference to “$300,000,000”.

(c)  As of the Acquisition Closing Date, Section 2.09(a) of the Credit Agreement is hereby amended by replacing the reference to “September 30, 2007” with a reference to “September 30, 2008”.

(d)  As of the Acquisition Closing Date, Section 6.14(a) of the Credit Agreement is hereby amended by replacing the table therein with the following table:

Date or Period	Ratio
June 30, 2006 through December 31, 2006	4.75 to 1.00
January 1, 2007 through September 30, 2007	5.50 to 1.00

Thereafter	4.50 to 1.00

“the Loan Parties shall not be required to grant a security interest in any personal property of a type that would not constitute Pledged Collateral or Article 9 Collateral (each as defined in the Guarantee and Collateral Agreement) pursuant to Section 3.01 or Section 4.01 of the Guarantee and Collateral Agreement.”.

SECTION 3.  Representations and Warranties.  To induce the other parties hereto to enter into this Amendment, each Loan Party represents and warrants to the Agent, the Issuing Bank and each of the Lenders that, as of the Amendment Effective Date (as defined below):

(a)  This Amendment has been duly authorized, executed and delivered by each Loan Party, and the Credit Agreement, as amended hereby, constitutes a legal, valid and binding obligation of each Loan Party party thereto, and this Amendment constitutes a legal, valid and binding obligation of each Loan Party.

(b)  The representations and warranties set forth in Article III of the Credit Agreement are true and correct in all material respects on and as of the Amendment Effective Date with the same effect as though made on and as of the Amendment Effective Date, except to the extent such representations and warranties expressly relate to an earlier date (in which case such representations and warranties were true and correct in all material respects as of such earlier date).

(c)  No Default or Event of Default has occurred and is continuing.

SECTION 4.  Effectiveness.  This Amendment shall become effective as of the date first set forth above on the date (the “Amendment Effective Date”) occurring on or prior to February 2, 2007, that:

(a)  The Agent (or its counsel) shall have received counterparts of this Amendment that, when taken together, bear the signatures of the Borrower, each Subsidiary Guarantor, the Agent and the Requisite Lenders.  As used herein, the term “Requisite Lenders” shall mean (x) the Required Lenders and (y) the Required Revolving Lenders.

(b)  The representations and warranties set forth in Sections 3(b) and (c) hereof shall be true and correct, and the Agent shall have received a certificate to that effect dated as of the Amendment Effective Date and executed by the chief financial officer of the Borrower.

(c)  The Agent shall notify the Borrower and the Lenders of the effectiveness of this Amendment.

SECTION 5.  Conditions Precedent to Additional Term Loans and Additional Revolving Credit Commitments.  The obligations of the Additional Term Lenders to make Additional Term Loans and the Increasing Revolving Credit Lenders to provide additional Revolving Credit Commitments, as the case may be, on the closing date of the Acquisition (the “Acquisition Closing Date”), are subject to the satisfaction of each of the following conditions:

(b)  On the Acquisition Closing Date, the representations and warranties set forth in Section 3(b) hereof shall be true and correct as if made as of the Acquisition Closing Date; provided that this condition shall be deemed satisfied (other than with respect to the Specified Representations (as defined below)) if and to the extent the conditions in the Agreement and Plan of Merger dated as of January 9, 2007, among the Company, the Borrower and Project Coffee Acquisition Co. (the “Merger Agreement”) relating to (a) the accuracy of the representations and warranties of the Company and (b) the absence of a Material Adverse Effect (as defined in the Merger Agreement)after January 9, 2007 shall have been satisfied (without giving effect to any waiver, amendment or other modification to such conditions in a manner materially adverse to the Lenders effected without the consent of the Agent). For purposes of this paragraph (b), “Specified Representations” shall mean the representations and warranties set forth in Sections 3.01, 3.02, 3.03(b), (c) (only with respect to the constitutional documents of any Loan Party or its subsidiaries) and (d), 3.08, 3.16, 3.18 and 3.19 of the Credit Agreement.

(c)  On the Acquisition Closing Date and immediately thereafter, no Event of Default of a type described in paragraph (a), (b), (f) or (g) of Article VII of the Credit Agreement shall have occurred and be continuing.

(d)  The Agent shall have received a certificate dated as of the Acquisition Closing Date and executed by the chief financial officer of the Borrower that the conditions set forth in paragraphs (b) and (c) of this Section 5 have been satisfied.

(e)  The Agent shall have received such legal opinions, board resolutions and other closing certificates, documentation, approvals and consents as shall be reasonably requested by the Agent, in each case consistent with those delivered on the Closing Date under Section 4.02 of the Credit Agreement.

(f)  The Lenders and the Agent shall have received all fees required to be paid, and all expenses for which invoices have been presented (including the reasonable documented fees and expenses of legal counsel), on or before the Acquisition Closing Date.

(g)  The Agent shall have received the results of recent lien and judgment searches in each of the jurisdictions contemplated by the Company Perfection Certificate (as defined below), and such searches shall reveal no material judgments and no liens on any of the assets of the Loan Parties except for Permitted Liens or Liens discharged on or prior to the Acquisition Closing Date pursuant to the pay-off letter referred to in paragraph (h) below.

(h)  None of the Company and its subsidiaries (the “Company Loan Parties”) shall have any Indebtedness for borrowed money outstanding.  The Agent shall have a received pay-off letter reasonably satisfactory to it in respect of the repayment of

5

the Company’s existing credit agreement, confirming that all Liens upon any of the property of the Company Loan Parties, if any, will be terminated concurrently with such payment and all letters of credit issued for the account of a Company Loan Party thereunder will be cash collateralized or supported by a letter of credit issued under the Credit Agreement.

(i)  The Agent shall have received a customary certificate from the chief financial officer of Holdings certifying that Holdings and its Subsidiaries, on a consolidated basis after giving effect to the transactions contemplated hereby to occur on the Acquisition Closing Date, are solvent (within the meaning of Section 3.13 of the Credit Agreement).

(k)  With respect to the Company Loan Parties, (i) the Agent shall have received a completed perfection certificate (the “Company Perfection Certificate”) dated the Acquisition Closing Date and signed by a Responsible Officer of the Borrower, together with all attachments contemplated thereby, in form and substance reasonably satisfactory to the Agent, (ii) each document (including any Uniform Commercial Code financing statement) required by the Collateral Documents or under law or reasonably requested by the Agent to be filed, registered or recorded in order to create in favor of the Agent, for the benefit of the Lenders, a perfected Lien on the Collateral described therein, prior and superior in right to any other Person (other than with respect to Permitted Liens), shall be in proper form for filing, registration or recordation and (iii) the Agent, on behalf of the Lenders, shall have a security interest in the Collateral of the type and priority described in the Collateral Documents (subject to Liens expressly permitted by Section 6.06 of the Credit Agreement); it being understood that with respect to any Collateral the security interest in which may not be perfected by the filing of a UCC financing statement or the delivery of stock certificates, if the perfection of the Agent’s security in such Collateral may not be accomplished prior to the Acquisition Closing Date after the use of commercially reasonable efforts to do so, then such perfection shall not constitute a condition under this paragraph (k) and the Borrower agrees to take or cause to be taken such actions as may be required to perfect such security interests within 15 days after the Acquisition Closing Date.  Pursuant to Section 5.11 of the Credit Agreement and Section 7.16 of the Guarantee and Collateral Agreement, each Company Loan Party shall have executed and delivered a Joinder Agreement and a supplement in the form of Exhibit A to the Guarantee and Collateral Agreement and shall be a Loan Party, Subsidiary Guarantor and Grantor for all purposes of this Amendment and each other Loan Document.

(m)  The Merger (as defined in the Merger Agreement) shall have been, or substantially simultaneously with the funding of Additional Term Loans on the Acquisition Closing Date shall be, consummated in accordance with the Merger Agreement and applicable law, without giving effect to any waiver of any material terms or conditions of the Merger Agreement not approved by the Agent. The Agent shall have received copies of the Merger Agreement and all certificates and other documents delivered thereunder, certified by a Responsible Officer as being complete and correct.  There shall not have occurred after the date of the Merger Agreement any change, event or effect that has had, or is reasonably likely to have, individually or in the aggregate, a Material Adverse Effect; provided that  no Person shall be able to assert that any condition set forth in this paragraph has not been satisfied unless Credit Suisse shall also make such assertion.

(n)  The Borrower shall have received gross cash proceeds of not less than $300,000,000 from the issuance of the Senior Subordinated Notes.  The terms and conditions of the Senior Subordinated Notes, the indenture related thereto and all other documents executed and delivered with respect to the Senior Subordinated Notes or the indenture related thereto (collectively, the “Senior Subordinated Note Documents”) shall be reasonably satisfactory to the Agent. The Agent shall have received copies of the Senior Subordinated Note Documents, certified by a Responsible Officer as being complete and correct.

(b)  Subject to Section 5 above, Project Coffee Acquisition Co. shall not be required to become a Loan Party (and no Loan Party shall be required to pledge any

7

equity interest in Project Coffee Acquisition Co.) unless the Acquisition fails to occur within 15 Business Days after the Amendment Effective Date, in which case, within 20 Business Days after the Amendment Effective Date, Project Coffee Acquisition Co. shall be required to satisfy the requirements of Section 5.11 of the Credit Agreement.

SECTION 7.  Effect of Amendment.  Except as expressly set forth herein, this Amendment shall not by implication or otherwise limit, impair, constitute a waiver of, or otherwise affect the rights and remedies of the Lenders, the Issuing Bank or the Agent under the Credit Agreement or any other Loan Document, and shall not alter, modify, amend or in any way affect any of the terms, conditions, obligations, covenants or agreements contained in the Credit Agreement or any other Loan Document, all of which are ratified and affirmed in all respects and shall continue in full force and effect.  Nothing herein shall be deemed to entitle any Loan Party to a consent to, or a waiver, amendment, modification or other change of, any of the terms, conditions, obligations, covenants or agreements contained in the Credit Agreement or any other Loan Document in similar or different circumstances.  This Amendment shall apply and be effective only with respect to the provisions of the Credit Agreement specifically referred to herein.  After the date hereof, any reference to the Credit Agreement shall mean the Credit Agreement, as modified hereby.  This Amendment shall constitute a “Loan Document” for all purposes of the Credit Agreement and the other Loan Documents.

SECTION 8.  Counterparts.  This Amendment may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed an original, but all such counterparts together shall constitute but one and the same contract.  Delivery of an executed counterpart of a signature page of this Amendment by facsimile transmission shall be as effective as delivery of a manually executed counterpart hereof.

SECTION 9.  Applicable Law.  THIS AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

SECTION 10.  Headings.  The headings of this Amendment are for purposes of reference only and shall not limit or otherwise affect the meaning hereof.

SECTION 11.  Acknowledgment of Subsidiary Guarantors.  Each of the Subsidiary Guarantors hereby acknowledges receipt and notice of, and consents to the terms of, this Amendment, and affirms and confirms its guarantee of the Obligations and, if applicable, the pledge of and/or grant of a security interest in its assets as Collateral to secure the Obligations, all as provided in the Guarantee and Collateral Agreement and the other Security Documents, and acknowledges and agrees that such guarantee, pledge and/or grant of security interest continue in full force and effect in respect of, and to secure, the Obligations under the Credit Agreement, as amended hereby, and the other Loan Documents and that such Obligations shall include all Obligations in respect of the Additional Term Loans or Revolving Loans made pursuant to the additional Revolving Credit Commitments.

Exhibit 10.4

SUPPLEMENT NO. 2 dated as of February 7, 2007, to the Guarantee and Collateral Agreement dated as of June 23, 2006 (the “Guarantee and Collateral Agreement”), among TRANSDIGM INC., a Delaware corporation (the “Borrower”), TRANSDIGM GROUP INCORPORATED, a Delaware corporation (“Holdings”), each subsidiary of the Borrower listed on Schedule I thereto (each such subsidiary individually a “SubsidiaryGuarantor” and collectively, the “SubsidiaryGuarantors”; the Subsidiary Guarantors, Holdings and the Borrower are referred to collectively herein as the “Grantors”) and CREDIT SUISSE as administrative agent and collateral agent (in such capacity, the “Agent”) for the Secured Parties (as defined herein).

A.  Reference is made to the Credit Agreement dated as of June 23, 2006, as amended by Amendment No. 1, dated as of January 25, 2007 (as amended, supplemented or otherwise modified from time to time, the “Credit Agreement”), among the Borrower, Holdings, each subsidiary of the Borrower from time to time party thereto, the lenders named therein (the “Lenders”), and Credit Suisse, as administrative agent and collateral agent (in such capacity, the “Agent”) for the Lenders.

B.  Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to such terms in the Credit Agreement or the Guarantee and Collateral Agreement referred to therein, as applicable.

C.  The Grantors have entered into the Guarantee and Collateral Agreement in order to induce the Lenders to make Loans and the Issuing Bank to issue Letters of Credit.  Section 7.16 of the Guarantee and Collateral Agreement provides that additional Domestic Subsidiaries of the Loan Parties may become Subsidiary Guarantors and Grantors under the Guarantee and Collateral Agreement by execution and delivery of an instrument in the form of this Supplement.  Each undersigned Subsidiary (each a “New Subsidiary” and collectively, the “New Subsidiaries”) is executing this Supplement in accordance with the requirements of the Credit Agreement to become a Subsidiary Guarantor and a Grantor under the Guarantee and Collateral Agreement in order to induce the Lenders to make additional Loans and the Issuing Bank to issue additional Letters of Credit and as consideration for Loans previously made and Letters of Credit previously issued.

Accordingly, the Agent and each New Subsidiary agree as follows:

SECTION 1.  In accordance with Section 7.16 of the Guarantee and Collateral Agreement, each New Subsidiary by its signature below becomes a Grantor and Subsidiary Guarantor under the Guarantee and Collateral Agreement with the same force and effect as if originally named therein as a Grantor and Subsidiary Guarantor and each New Subsidiary hereby (a) agrees to all the terms and provisions of the Guarantee and Collateral Agreement applicable to it as a Grantor and Subsidiary Guarantor thereunder and (b) represents and warrants that the representations and warranties made by it as a Grantor and Subsidiary Guarantor thereunder are true and correct in all material respects on and as of the date hereof.  In furtherance of the foregoing, each New Subsidiary, as security for the payment and performance in full of the Secured Obligations (as defined in the Guarantee and Collateral Agreement), does hereby create

and grant to the Agent, its successors and assigns, for the benefit of the Secured Parties, their successors and assigns, a security interest in and lien on all of each New Subsidiary’s right, title and interest in and to the Collateral (as defined in the Guarantee and Collateral Agreement) of each New Subsidiary.  Each reference to a “Grantor” or a “Subsidiary Guarantor” in the Guarantee and Collateral Agreement shall be deemed to include each New Subsidiary.  The Guarantee and Collateral Agreement is hereby incorporated herein by reference.

SECTION 2.  Each New Subsidiary represents and warrants to the Agent and the other Secured Parties that this Supplement has been duly authorized, executed and delivered by it and constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms.

SECTION 3.  This Supplement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Supplement shall become effective when the Agent shall have received counterparts of this Supplement that, when taken together, bear the signatures of each New Subsidiary and the Agent.  Delivery of an executed signature page to this Supplement by facsimile transmission shall be as effective as delivery of a manually signed counterpart of this Supplement.
