On May 12, 2011 (the “Closing Date”), Sensata Technologies B.V. (the “Issuer”), an indirect, wholly-owned subsidiary of Sensata Technologies Holding N.V. (the “Company”), completed a series of financing transactions to refinance all of its existing indebtedness. The transactions included the private sale of $700.0 million aggregate principal amount of the Issuer’s 6.5% Senior Notes due 2019 (the “Notes”) and the execution of the New Senior Credit Facilities (as defined below) that provide the Issuer with a $1,100.0 million term loan and a $250.0 million revolving credit facility. The net proceeds from the issuance and sale of the Notes and borrowings under the term loan of the New Senior Credit Facilities together with cash on hand were or will be promptly used to (i) repay all of the amounts then outstanding under the Issuer’s existing term loans under the Existing Credit Agreement (as defined below), 8% Senior Notes due 2014 (the “Dollar Notes”) and 9% Senior Subordinated Notes due 2016 (the “Euro Notes” and together with the Dollar Notes, the “Existing Notes”), (ii) pay all accrued interest on such indebtedness and related redemption premiums and (iii) pay all fees and expenses in connection with these refinancing transactions.

Indenture

The Notes were issued pursuant to an indenture, dated May 12, 2011 (the “Indenture”), among the Issuer, certain of the Issuer’s subsidiaries party thereto, as guarantors (the “guarantors”), and The Bank of New York Mellon, as trustee (the “Trustee”). The Notes were offered at an original issue price of 100.0%.

Interest and Maturity

The Notes bear interest at a rate of 6.5% and mature on May 15, 2019. Interest is payable on the Notes on May 15 and November 15 of each year, commencing November 15, 2011.

Guarantees

The Issuer’s obligations under the Notes are guaranteed by the all of the Issuer’s existing and future wholly-owned subsidiaries that guarantee the Issuer’s obligations under the New Senior Credit Facilities. The Notes and the guarantees are unsecured senior obligations of the Issuer and the guarantors.

Covenants

The Indenture contains restrictive covenants that limit the ability of the Issuer and the Issuer’s restricted subsidiaries (as defined in the Indenture) to, among other things: incur additional debt or issue preferred stock; create liens; create restrictions on the Issuer’s subsidiaries’ ability to make payments to the Issuer; pay dividends and make other distributions in respect of the Issuer’s and its restricted subsidiaries’ capital stock; redeem or repurchase the Issuer’s capital stock or the capital stock of the Company or any other direct or indirect parent company of the Issuer or prepay subordinated indebtedness; make certain investments or certain other restricted payments; guarantee indebtedness; designate unrestricted subsidiaries; sell certain kinds of assets; enter into certain types of transactions with affiliates; and effect mergers or consolidations. These covenants are subject to important exceptions and qualifications set forth in the Indenture.

Certain of these covenants will be suspended if the Notes are assigned an investment grade rating by Standard & Poor’s Rating Services or Moody’s Investors Service, Inc. and no default has occurred and is continuing. The suspended covenants will be reinstated if the Notes are no longer rated investment grade by either rating agency and an event of default has occurred and is continuing at such time.

Events of Default

The Indenture provides for events of default (subject in certain cases to customary grace and cure periods) which include, among others, nonpayment of principal or interest when due, breach of covenants or other agreements in the Indenture, defaults in payment of certain other indebtedness, certain events of bankruptcy or insolvency and when the guarantees of significant subsidiaries (as defined in the Indenture) cease to be in full force and effect. Generally, if an event of default occurs,

the Trustee or the holders of at least 25% in principal amount of the then outstanding Notes may declare the principal and accrued but unpaid interest on all of the Notes to be due and payable immediately. All provisions regarding remedies in an event of default are subject to the Indenture.

Redemption

The Issuer may redeem the Notes, in whole or in part, at any time prior to May 15, 2015 at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to the redemption date, plus the “make-whole” premium set forth in the Indenture. The Issuer may redeem the Notes, in whole or in part, at any time on or after May 15, 2015 at the redemption prices set forth in the Indenture, plus accrued and unpaid interest, if any, to the redemption date. In addition, at any time on or prior to May 15, 2014, on one or more occasions, the Issuer may redeem up to 40% of the aggregate principal amount of the Notes with the net proceeds of certain equity offerings, as described in the Indenture, at a redemption price equal to 106.5% of the principal amount thereof, plus accrued and unpaid interest, if any, to the redemption date. If the Issuer experiences certain change of control events, holders of the Notes may require it to repurchase all or part of their Notes at 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the repurchase date.

The Notes are not registered under the Securities Act of 1933, as amended, and, unless so registered, may not be offered or sold in the United States absent an applicable exemption from registration requirements.

A copy of the Indenture is attached as Exhibit 4.1 to this Current Report on Form 8-K and is incorporated by reference herein. The description of the material terms of the Notes and the Indenture is qualified in its entirety by reference to such exhibit.

New Senior Credit Facilities

On the Closing Date, the Issuer, Sensata Technologies Finance Company, LLC and Sensata Technologies Intermediate Holding B.V. entered into a credit agreement (the “New Credit Agreement” or the “New Senior Credit Facilities”) with Morgan Stanley Senior Funding, Inc., as administrative agent, the initial l/c issuer and initial swing line lender named therein, and the other lenders party thereto. The New Senior Credit Facilities consists of a $1,100.0 million term loan and a $250.0 million revolving credit facility. The term loan was issued at 99.5% of par.

Amounts under the revolving credit facility may be borrowed, repaid and re-borrowed to fund the Borrowers’ (as defined below) working capital needs. No amounts under the term loans, once repaid, may be reborrowed.

Borrowers and Guarantors

The borrowers under the New Senior Credit Facilities are the Issuer and Sensata Technologies Finance Company, LLC (collectively, the “Borrowers”). All obligations under the New Senior Credit Facilities are or will be unconditionally guaranteed by certain of the Borrowers’ material U.S. subsidiaries and certain material subsidiaries located in the Netherlands, Mexico, Japan, South Korea and Malaysia (collectively, the “Credit Agreement Guarantors”).

Maturity and Amortization

The maturity date of the revolving credit facility is May 12, 2016. Loans made pursuant to the revolving credit facility must be repaid in full on or prior to such date, and all letters of credit issued thereunder will terminate unless cash collateralized prior to such time. The maturity date of the term loan facility is May 12, 2018. The principal amount of the term loan amortizes in equal quarterly installments in an aggregate annual amount equal to approximately 1% of the original principal amount, with the balance payable at maturity.

Subject to certain exceptions, the New Senior Credit Facilities are subject to mandatory prepayments equal to (a) 100% of the net cash proceeds from certain non-ordinary course sales or certain other dispositions of assets of the Borrowers and their restricted subsidiaries, subject to customary reinvestment provisions and certain other restrictions, (b) 100% (subject to reductions to 50% and 0% based on achievement of a Senior Secured Net Leverage Ratio (as defined below) of 1.5:1.0 and 1.0:1.0, respectively) of the net cash proceeds from issuances of certain indebtedness of the Borrowers and their restricted

subsidiaries (other than indebtedness permitted under the New Senior Credit Facilities), and (c) beginning with the fiscal year ending December 31, 2012, 50% (subject to reductions to 25% and 0% based on achievement of a Senior Secured Net Leverage Ratio of 1.5:1.0 and 1.0:1.0, respectively) of annual excess cash flow of the Issuer and its restricted subsidiaries.

Revolving credit facility borrowings denominated in Euros are maintained from time to time as EURIBOR Loans, which bear interest at the Applicable Rate in excess of EURIBOR (plus mandatory costs) as determined by the administrative agent for the respective interest period. The Eurodollar Rate applicable to term loans is subject to a 1.00% LIBOR floor.

For purposes of the New Senior Credit Facilities:

The incremental facilities may rank pari passu or junior in right of payment and security with the other borrowings under the New Senior Credit Facilities and mature no sooner than the final maturity of the term loan facility and the revolving credit facility, respectively. The incremental borrowing facilities may be incurred at any time with consent required only from those lenders that agree, at their sole discretion, to participate in such incremental facility and subject to certain conditions.
