On November 2, 2006, and in accordance with the terms of that certain Indenture, dated as of June 23, 2006, by and among TransDigm, TD Group, The Bank of New York Trust Company, N.A., as trustee (the “Trustee”), and the other parties named therein (the “Indenture”), TransDigm, TD Group, CDA, certain other direct and indirect subsidiaries of TransDigm named therein and the Trustee entered into that certain First Supplemental Indenture to the Indenture (the “First Supplemental Indenture”). In addition, on November 2, 2006, and in accordance with the terms of that certain (i) Credit Agreement, dated as of June 23, 2006, among TransDigm, TD Group and the other parties named therein (the “Credit Agreement”), and (ii) 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 (the “Guarantee and Collateral Agreement”), CDA and Credit Suisse entered into (x) Supplement No. 1 to the Guarantee and Collateral Agreement (“Supplement No. 1”) and (y) a Joinder Agreement to the Credit Agreement (the “Joinder Agreement”).

Pursuant to the terms of the First Supplemental Indenture and Supplement No. 1, CDA agreed to, among other things, guarantee all of the indebtedness of TransDigm outstanding under the Indenture and the Credit Agreement, respectively. In addition, under the terms of Supplement No. 1, CDA pledged substantially all of its assets to secure its guaranteed obligations under the Credit Agreement.  Pursuant to the terms of the Joinder Agreement, CDA has agreed that it will deemed to be a “Loan Party” and a “Loan Guarantor” for all purposes of the Credit Agreement.

Item 8.01               Other Events

On October 6, 2006, the Board of Directors of TD Group granted a waiver of its conflict of interest policy to W. Nicholas Howley, TD Group’s Chairman and Chief Executive Officer, to permit Mr. Howley to serve on the board of directors of Satair A/S, a Danish company listed on the Copenhagen Stock Exchange. The waiver of the conflict of interest policy was necessary because Satair A/S is a distributor of TD Group’s products, purchasing approximately $20 million of its products annually. In connection with the grant of the waiver, the Board of Directors determined that it was worthwhile and in TD Group’s best interests for Mr. Howley to serve as a director of Satair. Mr. Howley was elected to the Satair A/S board of directors on October 26, 2006.

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.

EXECUTION COPY

SUPPLEMENT NO. 1 (this “Supplement”) dated as of November 2, 2006, 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 “Subsidiary Guarantor” 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, 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 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.  The undersigned Subsidiary (the “New Subsidiary”) 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 the New Subsidiary agree as follows:

SECTION 1.           In accordance with Section 7.16 of the Guarantee and Collateral Agreement, the 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 the 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, the 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 the New Subsidiary’s right, title and interest in and to the Collateral (as defined in the Guarantee and Collateral Agreement) of the New Subsidiary.  Each reference to a “Grantor” or a “Subsidiary Guarantor” in the Guarantee and Collateral Agreement shall be deemed to include the New Subsidiary.  The Guarantee and Collateral Agreement is hereby incorporated herein by reference.

SECTION 2.           The 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 the 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.

SECTION 4.           The New Subsidiary hereby represents and warrants that (a) set forth on Schedule I attached hereto is a true and correct schedule of the location of any and all Collateral of the New Subsidiary and (b) set forth under its signature hereto, is the true and correct legal name of the New Subsidiary, its jurisdiction of formation and the location of its chief executive office.

SECTION 5.           Except as expressly supplemented hereby, the Guarantee and Collateral Agreement shall remain in full force and effect.

SECTION 6.           THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

SECTION 7.           In case any one or more of the provisions contained in this Supplement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and in the Guarantee and Collateral Agreement shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

SECTION 8.           All communications and notices hereunder shall be in writing and given as provided in Section 7.01 of the Guarantee and Collateral Agreement.

2

All communications and notices hereunder to the New Subsidiary shall be given to it at the address set forth under its signature below.
