Explanation of Responses:

1. The filing of this Form 4 shall not be construed as an admission that any of BlueMountain Capital Management, LLC ("BMCM"), GP Holdings (as defined in Footnote 5) or the General Partners (as defined in Footnote 5) is or was for the purposes of Section 16(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise the beneficial owner of any of the shares of Common Stock, par value $0.0001 per share (the "Common Stock"), Series B convertible preferred stock ("Series B Stock"), or Series D Warrants to purchase shares of Common Stock ("Series D Warrants") of SAExploration Holdings, Inc. (the "Issuer"). Pursuant to Rule 16a-1(a)(4) of the Exchange Act, each of BMCM, GP Holdings and the General Partners disclaims such beneficial ownership, except to the extent of its respective pecuniary interest in such securities.

2. BMCM is the investment manager of each of: (i) Blue Mountain Credit Alternatives Master Fund L.P. ("BMCA"), which was the direct owner of 149,045 shares of Series B Stock which converted into 3,239,910 Series D Warrants; (ii) BlueMountain Guadalupe Peak Fund L.P. ("BMGP"), which was the direct owner of 7,181 shares of Series B Stock which converted into 156,099 Series D Warrants; (iii) BlueMountain Kicking Horse Fund L.P. ("BMKH"), which was the direct owner of 5,468 shares of Series B Stock which converted into 118,862 Series D Warrants (iv) BlueMountain Summit Trading L.P. ("BMST" and, together with BMCA, BMGP and BMKH, the "Partnerships"), which was the direct owner of 14,260 shares of Series B Stock which converted into 309,981 Series D Warrants (v) BlueMountain Timberline Ltd. ("BMT"), which was the direct owner of 8,630 shares of Series B Stock which converted into 187,597 Series D Warrants; and

3. (vi) BlueMountain Montenvers Fund SCA SICAV-SIF ("BMM" and, together with the Partnerships and BMT, the "Funds"), which was the direct owner of 33,239 shares of Series B Stock which converted into 722,543 Series D Warrants. BMCM, although it directs the voting and disposition of the securities held by the Funds, only receives an asset-based fee relating to the securities held by the Funds.

4. (i) Blue Mountain CA Master Fund GP, Ltd. ("BMCA GP") is the general partner of BMCA and has an indirect profits interest in the securities beneficially owned by it; (ii) BlueMountain Summit Opportunities GP II, LLC ("BMST GP") is the general partner of BMST and has an indirect profits interest in the securities beneficially owned by it; (iii) BlueMountain Long/Short Credit GP, LLC ("BMGP GP") is the general partner of BMGP and has an indirect profits interest in the securities beneficially owned by it; (iv) BlueMountain Montenvers GP S.a r.l. ("BMM GP") is the general partner of BMM and has an indirect profits interest in the securities beneficially owned by it; and

5. (v) BlueMountain Kicking Horse Fund GP, LLC ("BMKH GP" and, together with BMCA GP, BMST GP, and BMGP GP, the "General Partners") is the general partner of BMKH and has an indirect profits interest in the securities beneficially owned by it. BlueMountain GP Holdings, LLC ("GP Holdings") is the sole owner of each of the General Partners and thus has an indirect profits interest in the securities beneficially owned by the Partnerships. BMCM is the sole owner of BMM GP and thus has an indirect profits interest in the securities beneficially owned by BMM.

6. The Reporting Persons are jointly filing this Form 4 pursuant to Rule 16(a)-3(j) under the Exchange Act. The Form 4 for certain additional Reporting Persons is being filed separately and simultaneously with this Form 4 due to the limitation of ten Reporting Persons per filing.

7. On March 8, 2018, the Reporting Person received the Series D Warrants to purchase shares of Common Stock in connection with a mandatory conversion of the Series B Preferred Stock. As a result of the mandatory conversion, the Issuer converted all of Reporting Person's outstanding shares of the Series B Preferred Stock into Series D Warrants.

8. Each Series D Warrant is immediately exercisable at the option of the holder for one share of Common Stock at a price equal to $0.0001. The Series D Warrants are also exercisable at the option of the Issuer in connection with a full redemption of the Series A Preferred Stock or upon a change of control of the Issuer. At all times a holder of Series D Warrants, who is not a beneficial owner of 10% or more of the outstanding Common Stock, may exercise only up to that number of Series D Warrants so that, upon exercise, the aggregate beneficial ownership of Common Stock of such holder and all persons affiliated with such holder, is not more than 9.99% of Common Stock then outstanding (other than in connection with a change of control of the Issuer). As of the filing date, Reporting Persons may be deemed to beneficially own more than 10% of the outstanding Common Stock.
