Exterran Senior Secured Credit Facility

As of September 30, 2014, we had $386.5 million in outstanding borrowings and $126.4 million in outstanding letters of credit under our senior secured revolving credit facility (the “Credit Facility”). At September 30, 2014, taking into account guarantees through letters of credit, we had undrawn and available capacity of $387.1 million under the Credit Facility.

The Partnership Revolving Credit Facility and Term Loan

In March 2013, the Partnership amended its senior secured credit agreement (the “Partnership Credit Agreement”) to reduce the borrowing capacity under its revolving credit facility by $100.0 million to $650.0 million and extend the maturity date of the term loan and revolving credit facilities to May 2018. As a result of the March 2013 amendment, we expensed $0.7 million of unamortized deferred financing costs, which is reflected in interest expense in our condensed consolidated statements of operations. The Partnership incurred transaction costs of approximately $4.3 million related to the amendment to the Partnership Credit Agreement. These costs were included in intangible and other assets, net, and are being amortized over the terms of the facilities. As of September 30, 2014, the Partnership had undrawn and available capacity of $270.0 million under its revolving credit facility.

The Partnership 6% Senior Notes Due April 2021

In March 2013, the Partnership issued $350.0 million aggregate principal amount of 6% senior notes due April 2021 (the “Partnership 2013 Notes”). The Partnership used the net proceeds of $336.9 million, after original issuance discount and issuance costs, to repay borrowings outstanding under its revolving credit facility. The Partnership incurred $7.6 million in transaction costs related to this issuance. These costs were included in intangible and other assets, net, and are being amortized to interest expense over the term of the Partnership 2013 Notes. The Partnership 2013 Notes were issued at an original issuance discount of $5.5 million, which is being amortized using the effective interest method at an interest rate of 6.25% over their term. In January 2014, holders of the Partnership 2013 Notes exchanged their Partnership 2013 Notes for registered notes with the same terms.

The Partnership 6% Senior Notes Due October 2022

In April 2014, the Partnership issued $350.0 million aggregate principal amount of the Partnership 2014 Notes. The Partnership received net proceeds of $337.4 million, after original issuance discount and issuance costs, from this offering, which it used to fund a portion of the April 2014 MidCon Acquisition and repay borrowings under its revolving credit facility. The Partnership 2014 Notes were issued at an original issuance discount of $5.7 million, which is being amortized using the effective interest method at an interest rate of 6.25% over their term. The Partnership incurred $6.9 million in transaction costs related to this issuance. These costs were included in intangible and other assets, net, and are being amortized to interest expense over the term of the Partnership 2014 Notes. The Partnership 2014 Notes have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws, and unless so registered, may not be offered or sold in the U.S. except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws. The Partnership offered and issued the Partnership 2014 Notes only to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to persons outside the U.S. pursuant to Regulation S. Pursuant to a registration rights agreement, the Partnership is required to register the Partnership 2014 Notes no later than 365 days after April 7, 2014.

The Partnership 2014 Notes are guaranteed on a senior unsecured basis by all of the Partnership’s existing subsidiaries (other than EXLP Finance Corp., which is a co-issuer of the Partnership 2014 Notes) and certain of the Partnership’s future subsidiaries. The Partnership 2014 Notes and the guarantees, respectively, are the Partnership’s and the guarantors’ general unsecured senior obligations, rank equally in right of payment with all of the Partnership’s and the guarantors’ other senior obligations, and are effectively subordinated to all of the Partnership’s and the guarantors’ existing and future secured debt to the extent of the value of the collateral securing such indebtedness. In addition, the Partnership 2014 Notes and guarantees are effectively subordinated to all existing and future indebtedness and other liabilities of any future non-guarantor subsidiaries.

Prior to April 1, 2018, the Partnership may redeem all or a part of the Partnership 2014 Notes at a redemption price equal to the sum of (i) the principal amount thereof, plus (ii) a make-whole premium at the redemption date, plus accrued and unpaid interest, if any, to the redemption date. In addition, the Partnership may redeem up to 35% of the aggregate principal amount of the Partnership 2014 Notes prior to April 1, 2017 with the net proceeds of one or more equity offerings at a redemption price of 106.000% of the principal amount of the Partnership 2014 Notes, plus any accrued and unpaid interest to the date of redemption, if at least 65% of the aggregate principal amount of the Partnership 2014 Notes issued under the indenture remains outstanding after such redemption and the redemption occurs within 180 days of the date of the closing of such equity offering. On or after April 1, 2018, the Partnership may redeem all or a part of the Partnership 2014 Notes at redemption prices (expressed as percentages of principal amount) equal to 103.000% for the twelve-month period beginning on April 1, 2018, 101.500% for the twelve-month period beginning on April 1, 2019 and 100.000% for the twelve-month period beginning on April 1, 2020 and at any time thereafter, plus accrued and unpaid interest, if any, to the applicable redemption date of the Partnership 2014 Notes.

4.25% Convertible Senior Notes

In June 2009, we issued $355.0 million aggregate principal amount of 4.25% convertible senior notes due June 2014 (the “4.25% Notes”). The 4.25% Notes, after taking into consideration dividends declared, were convertible upon the occurrence of certain conditions into shares of our common stock at a conversion rate of 43.5084 shares of our common stock per $1,000 principal amount of the convertible notes, equivalent to a conversion price of approximately $22.98 per share of common stock. In June 2014, we completed our redemption of the 4.25% Notes in exchange for $370.0 million in cash and 6.8 million shares of our common stock. We financed the cash payment to redeem the 4.25% Notes through borrowings under our revolving credit facility.

In connection with the offering of the 4.25% Notes, we purchased call options on our stock at approximately $22.98 per share of common stock, after taking into consideration dividends declared, and sold warrants on our stock at approximately $32.33 per share of common stock, after taking into consideration dividends declared. These transactions economically adjust the effective conversion price to $32.33 for $325.0 million of the 4.25% Notes. In June 2014, we exercised our call options to acquire 6.5 million shares of our common stock. The cost of the common shares acquired was recorded as treasury stock in our condensed consolidated balance sheets based on the original cost of the call options of $89.4 million. Counterparties to our warrants have the right to exercise the warrants in equal installments for 80 trading days beginning in September 2014. During the third quarter of 2014, 498,254 common shares were issued out of treasury stock pursuant to warrants exercised.

4.75% Convertible Senior Notes

In January 2013, we redeemed for cash all $143.8 million principal amount outstanding of our 4.75% convertible senior notes (the “4.75% Notes”) at a redemption price of 100% of the principal amount thereof plus accrued but unpaid interest to, but excluding, the redemption date. Upon redemption, the 4.75% Notes were no longer deemed outstanding, interest ceased to accrue thereon and all rights of the holders of the 4.75% Notes ceased to exist. We financed the redemption of the 4.75% Notes through borrowings under our revolving credit facility. As a result of the redemption, we expensed $0.9 million of unamortized deferred financing costs in the first quarter of 2013, which is reflected in interest expense in our condensed consolidated statements of operations.
