Senior Secured Notes

On July 2, 2014, the Corporation entered into an Indenture ("Indenture") under which it issued $150,000 of senior secured notes due July 15, 2019, in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to non-U.S. persons in offshore transactions pursuant to Regulation S under the Securities Act. On June 19, 2015, all outstanding senior secured notes were exchanged for an equal amount of new senior secured notes ("Notes"), which are substantially identical in terms to the existing senior secured notes except that the Notes are registered under the Securities Act. The Notes bear interest at the annual rate of 10% payable semi-annually in arrears on January 15 and July 15 of each year, commencing on January 15, 2015. For a complete discussion of the terms and security for the Notes, see Note 6 of Notes to Consolidated Financial Statements included in the Corporation's Annual Report on Form 10-K for the year ended December 31, 2014.

The proceeds from the original issuance of the senior secured notes were used to pay the amounts outstanding under the 2012 Credit Agreement, pay the note payable to the Former SAE common stockholders, pay related fees and expenses, fund the purchase of equipment related to the Corporation’s Alaska operations, and for general corporate purposes. The repayment and termination of the 2012 Credit Agreement resulted in a $17,157 charge to loss on early extinguishment of debt in the three and nine months ended September 30, 2014. The charge consisted of prepayment penalties of $8,877, write-off of unamortized loan discount and issuance costs totaling $7,983, and legal fees of $297.

On August 26, 2015, the Corporation entered into a privately-negotiated exchange agreement with certain funds managed by Fidelity Management & Research Company ("Holders") to exchange $10,000 principal amount of Notes ("Exchanged Notes") for 2,366,307 shares of the Corporation’s common stock ("Exchanged Stock"), as determined using a 30-day volume weighted average share price as of August 26, 2015. In connection with the exchange, the Corporation paid all accrued unpaid interest on the Exchanged Notes to the Holders in cash, and the Exchanged Notes were cancelled. The Exchanged Stock was valued at $6,602 based on the $2.79 average share price on August 27, 2015, the closing date ("Closing Date") of the exchange. The exchange resulted in a gain on early extinguishment of debt of $3,014 in the three and nine months ended September 30, 2015, consisting of the difference between the principal amount of the Exchanged Notes less the fair value of the Exchanged Stock, reduced by the Exchanged Notes prorata portion of the Notes unamortized deferred loan issuance costs on the Closing Date of $343 and legal fees of $41.

The Indenture contains covenants which include limitations on the Corporation's ability to: (i) transfer or sell assets; (ii) pay dividends, redeem subordinated indebtedness or make other restricted payments; (iii) incur or guarantee additional indebtedness or, with respect to the Corporation's restricted subsidiaries, issue preferred stock; (iv) create or incur liens; (v) incur dividend or other payment restrictions affecting its restricted subsidiaries; (vi) consummate a merger, consolidation or sale of all or substantially all of its or its subsidiaries’ assets; (vii) enter into transactions with affiliates; (viii) engage in business other than its current business and reasonably related extensions thereof; and (ix) take or omit to take any actions that would adversely affect or impair in any material respect the collateral securing the Notes. The Corporation is in compliance with the Indenture covenants as of September 30, 2015.

Equipment Note Payable

On November 18, 2014, the Corporation entered into a note payable to Sercel, Inc. in the amount of $1,838, bearing interest at the annual rate of 8%. The note payable is secured by geophones and related accessories which were delivered in December 2014. A payment of $184 was made upon delivery of the equipment with principal and interest payments of $144 due monthly thereafter until the note payable is fully paid on December 15, 2015.
