Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(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 2) or the General Partner (as defined in Footnote 2) 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 (i) the shares of Common Stock, par value $0.0001 per share (the "Common Stock"), of Chart Acquisition Corp. (the "Issuer"), or (ii) the warrants to purchase Common Stock (the "Warrants"). Pursuant to Rule 16a-1(a)(4) of the Exchange Act, each of BMCM, GP Holdings, and the General Partner disclaims such beneficial ownership, except to the extent of its respective pecuniary interest.
(2) BMCM is the investment manager of BlueMountain Long/Short Credit Master Fund L.P. ("BMLSC"). BMCM, although it directs the voting and disposition of the Common Stock and Warrants held by BMLSC, only receives an asset-based fee relating to the Common Stock and Warrants held by BMLSC. BlueMountain Long/Short Credit GP, LLC (the "General Partner") is the general partner of BMLSC and has an indirect profits interest in the Common Stock and Warrants beneficially owned by it. BlueMountain GP Holdings, LLC ("GP Holdings") is the sole owner of the General Partner and thus has an indirect profits interest in the Common Stock and Warrants beneficially owned by BMLSC.
(3) No expiration date or date exercisable are provided because the Warrants may be exercised only subject to certain restrictions set forth in Exhibit 4.4 to the Issuer's report on Form 8-K filed with the Securities and Exchange Commission on December 19, 2012.
(4) In connection with a redemption offer by the Issuer that closed on June 18, 2015, BMLSC redeemed 75,768 shares of Common Stock, representing all of the Common Stock held by it.
(5) In connection with a tender offer by the Issuer that closed on June 18, 2015, BMLSC tendered to the Issuer 75,768 Warrants, representing all of the Warrants held by it.
(6) The Reporting Persons are jointly filing this Form 4 pursuant to Rule 16(a)-3(j) under the Exchange Act.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.

Potential persons who are to respond to the collection of information contained in this form are not required to respond unless the form displays a currently valid OMB number.
