Following the CSI Acquisition, the completion of the Compressco Partners offering of the additional 17,572,000 common units, and the contribution by Compressco Partners GP Inc., our aggregate ownership percentage in Compressco Partners was reduced to approximately 44% from approximately 82%. Through our Compressco Partners GP Inc. subsidiary, we will continue to manage and control Compressco Partners, and, accordingly, we will continue to consolidate the balance sheet of Compressco Partners, including the long-term debt of Compressco Partners, as part of our consolidated balance sheet. We and our subsidiaries, excluding Compressco Partners and its subsidiaries, are obligated under a bank credit agreement and senior notes, neither of which are obligations of Compressco Partners. Compressco Partners is obligated under a separate bank credit agreement and senior notes, neither of which are obligations of TETRA Technologies, Inc. and its other subsidiaries.

Our Bank Credit Facility - On August 4, 2014, in connection with the CSI Acquisition, we borrowed $40.0 million under our bank credit facility to fund the purchase of 1,391,113 common units of Compressco Partners and to fund a contribution of $7.3 million by our wholly owned subsidiary Compressco Partners GP Inc. to maintain its approximately 2% general partners interest in Compressco Partners.

On September 30, 2014, we entered into an amendment (the Third Amendment) of our bank credit facility. The Third Amendment amends our credit facility, which was scheduled to expire on October 29, 2015, by extending the maturity date of the credit facility until September 30, 2019 and decreasing the revolving commitment from $278 million to $225 million. The Third Amendment also revised certain financial covenants and the range of applicable interest rate spreads. The facility remains unsecured and guaranteed by certain of our material domestic subsidiaries. In connection with the reduction of the commitment capacity as part of the Third Amendment, we charged approximately $0.1 million of unamortized deferred financing costs to expense.

Compressco Partners 7.25% Senior Notes - On July 29, 2014, Compressco Partners, Compressco Finance Inc., a Delaware corporation and an indirect wholly owned subsidiary of Compressco Partners (Compressco Finance and, together with Compressco Partners, the Issuers), and the guarantors named therein (the Guarantors and, together with the Issuers, the Obligors), entered into the Note Purchase Agreement (the Note Purchase Agreement) with Merrill Lynch, Pierce, Fenner & Smith Incorporated on behalf of the initial purchasers named therein (collectively, the Initial Purchasers) related to the issuance and sale by the Issuers to the Initial Purchasers of $350.0 million aggregate principal amount of the Issuers’ 7.25% Senior Notes due 2022 (the Compressco Senior Notes) in a private offering (the Offering) exempt from the registration requirements under the Securities Act of 1933, as amended (the Securities Act). The Note Purchase Agreement contains customary representations and warranties of the parties thereto and indemnification and contribution provisions under which the Obligors, on one hand, and the Initial Purchasers, on the other, have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act.

The Issuers closed the Offering on August 4, 2014. Their obligations under the Compressco Senior Notes are jointly and severally, and fully and unconditionally, guaranteed on a senior unsecured basis initially by each of Compressco Partners’ domestic restricted subsidiaries (other than Compressco Finance) that guarantee Compressco Partners’ other indebtedness. The Compressco Senior Notes and the subsidiary guarantees thereof (together, the Compressco Securities) were issued pursuant to an indenture described below.

Compressco Partners used the net proceeds of the Offering of approximately $337.8 million (consisting of $350.0 million aggregate principal amount net of a $5.2 million discount and certain fees and offering expenses) to fund a portion of the $825.0 million cash purchase price for the CSI Acquisition, to pay certain acquisition expenses and to repay a portion of outstanding borrowings under the Compressco Partners’ then existing credit facility. During the three month period ended September 30, 2014, financing costs of approximately $8.4 million were incurred related to the Compressco Senior Notes. These costs are included in Other Assets and are being amortized over the term of the Compressco Senior Notes. The $5.2 million discount is being amortized using the effective interest method at an interest rate of 7.50% over the term of the Compressco Senior Notes. Approximately $0.1 million of discount amortization expense was recognized during the three months ended September 30, 2014.

Pursuant to the Note Purchase Agreement, CSI and any domestic subsidiaries of CSI required to guarantee the Compressco Senior Notes pursuant to the indenture governing the Compressco Senior Notes were joined as parties to the Note Purchase Agreement pursuant to a purchase agreement joinder, dated August 4, 2014.

The Obligors issued the Compressco Securities pursuant to the Indenture dated as of August 4, 2014 (the Indenture) by and among the Obligors and U.S. Bank National Association, as trustee (the Trustee). The Compressco Senior Notes accrue interest at a rate of 7.25% per annum. Interest on the Compressco Senior Notes is payable semi-annually in arrears on February 15 and August 15 of each year, beginning February 15, 2015. The Compressco Senior Notes are scheduled to mature on August 15, 2022.

On and after August 15, 2017, Compressco Partners may on one or more occasions redeem the Compressco Senior Notes, in whole or in part, upon not less than 30-days’ nor more than 60-days’ prior notice, at the following redemption prices (expressed as a percentage of principal amount), plus accrued and unpaid interest and liquidated damages thereon, if any, to the applicable redemption date, subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date, if redeemed during the 12-month period beginning on August 15 of the years indicated below:



Date	Price
2017	105.438	%
2018	103.625	%
2019	101.813	%
2020 and thereafter	100	%

In addition, any time or from time to time before August 15, 2017, Compressco Partners may redeem all or a part of the Compressco Senior Notes at a redemption price equal to 100% of the principal amount of the Compressco Senior Notes redeemed, plus an applicable "make whole" prepayment premium and interest up to the redemption date.

Prior to August 15, 2017, Compressco Partners may, on one or more occasions redeem up to 35% of the principal amount of the Compressco Senior Notes with an amount of cash not greater than the amount of the net cash proceeds from one or more equity offerings at a redemption price equal to 107.250% of the principal amount of the Compressco Senior Notes to be redeemed, plus accrued and unpaid interest and liquidated damages, if any, to the date of redemption, subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date, as long as (a) at least 65% of the aggregate principal amount of the Compressco Senior Notes originally issued on the issue date (excluding notes held by Compressco Partners and its subsidiaries) remains outstanding after each such redemption; and (b) the redemption occurs within 180 days after the date of the closing of the equity offering.

The Indenture contains customary covenants restricting Compressco Partners’ ability and the ability of its restricted subsidiaries to: (i) pay dividends and make certain distributions, investments and other restricted payments; (ii) incur additional indebtedness or issue certain preferred shares; (iii) create certain liens; (iv) sell assets; (v) merge, consolidate, sell or otherwise dispose of all or substantially all of its assets; (vi) enter into transactions with affiliates; and (vii) designate its subsidiaries as unrestricted subsidiaries under the Indenture. These covenants are subject to a number of important limitations and exceptions, including certain provisions permitting Compressco Partners, subject to the satisfaction of certain conditions, to transfer assets to certain of its unrestricted subsidiaries. Moreover, if the Compressco Senior Notes receive an investment grade rating from at least two rating agencies and no default has occurred and is continuing under the Indenture, many of the restrictive covenants in the Indenture will be terminated. The Indenture also contains customary events of default and acceleration provisions relating to such events of default, which provide that upon an event of default under the Indenture, the Trustee or the holders of at least 25% in aggregate principal amount of the Compressco Senior Notes then outstanding may declare all amounts owing under the Compressco Senior Notes to be due and payable.

The offer and sale of the Compressco Securities were not registered under the Securities Act or applicable state securities laws, and the Compressco Securities may not be offered or sold in the U.S. absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state laws. In connection with the Offering of the Compressco Senior Notes, the Obligors entered into the Registration Rights Agreement dated as of August 4, 2014 (the Registration Rights Agreement) with Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representative of the Initial Purchasers, obligating the Obligors to use commercially reasonable efforts to file a registration statement with the Securities and Exchange Commission (the SEC) registering an exchange offer by the Obligors that would allow holders of the Compressco Securities to exchange their restricted Compressco Securities for registered freely tradable notes and guarantees having substantially the same terms as the Compressco Securities and evidencing the same indebtedness as the restricted Compressco Securities. Under certain circumstances, in lieu of a registered exchange offer, the Obligors must use commercially reasonable efforts to file a shelf registration statement for the resale of the Compressco Securities. If, among other things, such exchange offer registration statement is not declared effective by the SEC on or prior to 365 days after the closing of the Offering, or the exchange offer has not been consummated within 30 business days following the expiration of the 365-day period following the closing of the Offering to have an exchange offer registration statement declared effective by the SEC, the Obligors will be required to pay to the holders of the Compressco Senior Notes liquidated damages in an amount equal to 0.25% per annum on the principal amount of the Compressco Senior Notes held by such holder during the 90-day period immediately following the occurrence of such registration default, and if such registration default is not cured, such amount of liquidated damages shall increase by 0.25% per annum at the end of such 90-day period, such that the maximum amount of liquidated damages for all registration defaults would be one-half of one percent (0.5%) per annum.

Compressco Partners New Bank Credit Facility - On August 4, 2014, in connection with the CSI Acquisition, Compressco Partners entered into a new credit agreement (the New Partnership Credit Agreement), and it borrowed $210.0 million, which was used to fund, in part, Compressco Partners' $825.0 million CSI Acquisition purchase price. In addition, the New Partnership Credit Agreement borrowings were used to pay fees and expenses related to the CSI Acquisition, the Compressco Senior Notes offering, and the New Partnership Credit Agreement, and to repay the $38.1 million balance outstanding under Compressco Partners' previous Partnership Credit Agreement dated October 15, 2013, which was then terminated. As a result, approximately $0.8 million of unamortized deferred financing costs associated with that terminated Partnership Credit Agreement was charged to earnings and reflected in other expense during the three month period ended September 30, 2014. Under the New Partnership Credit Agreement, Compressco Partners and Compressco Partners Sub, Inc. were named as the borrowers, and all obligations under the New Partnership Credit Agreement are guaranteed by all of Compressco Partners' existing and future, direct and indirect, domestic restricted subsidiaries, other than domestic subsidiaries that are wholly owned by foreign subsidiaries. We are not a borrower or a guarantor under the New Partnership Credit Agreement. The New Partnership Credit Agreement includes a maximum credit commitment of $400.0 million, and included within such amount is availability for letters of credit (with a sublimit of $20.0 million) and swingline loans (with a sublimit of $60.0 million). During the three month period ended September 30, 2014, Compressco Partners incurred financing costs of approximately $7.3 million related to the New Partnership Credit Agreement. These costs are included in Other Assets and are being amortized over the term of the New Partnership Credit Agreement.

On August 11, 2014, the underwriters exercised their option and purchased 2,292,000 additional common units for the Offering Price of $23.50 per common unit resulting in additional net proceeds of $51.7 million ($53.9 million gross proceeds less underwriting discount). Following the receipt of proceeds from this option exercise, a portion of the outstanding balance under the New Partnership Credit Agreement was repaid.

The New Partnership Credit Agreement is available to provide Compressco Partners' working capital needs, letters of credit, and for general partnership purposes, including capital expenditures and potential future expansions or acquisitions. So long as Compressco Partners is not in default, the New Partnership Credit Agreement can also be used to fund Compressco Partners’ quarterly distributions at the option of the board of directors of Compressco Partners' general partner (provided, that after giving effect to such distributions, the borrowers will be in compliance with the financial covenants). Borrowings under the New Partnership Credit Agreement are subject to the satisfaction of customary conditions, including the absence of a default. The maturity date of the New Partnership Credit Agreement is August 4, 2019.

Borrowings under the New Partnership Credit Agreement bear interest at a rate per annum equal to, at Compressco Partners' option, either (a) LIBOR (adjusted to reflect any required bank reserves) for an interest period equal to one, two, three, or six months (as selected by Compressco Partners), plus a leverage-based margin or (b) a base rate plus a leverage-based margin; such base rate shall be determined by reference to the highest of (1) the prime rate of interest per annum announced from time to time by Bank of America, N.A. (2) the Federal Funds rate plus 0.50% per annum and (3) LIBOR (adjusted to reflect any required bank reserves) for a one month interest period on such day plus 1.00% per annum. Initially, from the closing date until the delivery of the financial statements for the first full fiscal quarter after closing, LIBOR based loans will have an applicable margin of 2.75% per annum, and base rate loans will have an applicable margin of 1.75% per annum; thereafter, the applicable margin will range between 1.75% and 2.50% per annum for LIBOR based loans and 0.75% and 1.50% per annum for base rate loans based on Compressco Partners' consolidated total leverage ratio when financial statements are delivered. In addition to paying interest on outstanding principal under the New Partnership Credit Agreement, Compressco Partners is required to pay a commitment fee in respect of the unutilized commitments thereunder initially at the rate of 0.50% per annum until the delivery of the financial statements for the first full quarter after the closing date and thereafter at the applicable rate ranging from 0.375% to 0.50% per annum, paid quarterly in arrears based on Compressco Partners' consolidated total leverage ratio. Compressco Partners is also required to pay a customary letter of credit fee equal to the applicable margin on revolving credit LIBOR loans, fronting fees and other fees, agreed to with the administrative agent and lenders.

The New Partnership Credit Agreement requires Compressco Partners to maintain (i) a minimum consolidated interest coverage ratio (ratio of consolidated earnings before interest, taxes, depreciation, and amortization (EBITDA) to consolidated interest charges) of 3.0 to 1.0, (ii) a maximum consolidated total leverage ratio (ratio of consolidated total indebtedness to consolidated EBITDA) of 5.5 to 1.0 (with step downs to 5.0 to 1.0), and (iii) a maximum consolidated secured leverage ratio (consolidated secured indebtedness to consolidated EBITDA) of 4.0 to 1.0, in each case, as of the last day of each fiscal quarter, calculated on a trailing four quarters basis. In addition, the New Partnership Credit Agreement includes customary negative covenants that, among other things, limit Compressco Partners' ability to incur additional debt, incur, or permit certain liens to exist, or make certain loans, investments, acquisitions, or other restricted payments. The New Partnership Credit Agreement provides that Compressco Partners can make distributions to holders of its common and subordinated units, but only if there is no default or event of default under the facility.

All obligations under the New Partnership Credit Agreement and the guarantees of those obligations are secured, subject to certain exceptions, by a first lien security interest in substantially all of Compressco Partners' assets and the assets of its existing and future domestic subsidiaries, and all of the capital stock of its existing and future subsidiaries (limited in the case of foreign subsidiaries, to 65% of the voting stock of first tier foreign subsidiaries).
