(a) This Schedule 13D is jointly filed by Nokomis
Capital and Mr. Brett Hendrickson. Because Mr. Hendrickson is the principal of Nokomis Capital (with Mr. Hendrickson and Nokomis Capital hereinafter referred to as the Reporting Persons), the Reporting Persons may be
deemed, pursuant to Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the Act), to be the beneficial owners of all of the shares of Common Stock held by the Nokomis Accounts. The Reporting Persons are filing this Schedule
13D jointly, as they may be considered a group under Section 13(d)(3) of the Act. However, neither the fact of this filing nor anything contained herein shall be deemed to be an admission by the Reporting Persons that such a group
exists.

(b) The principal place of business for each of the Reporting Persons is 2305 Cedar Springs Rd., Suite 420, Dallas, TX 75201.

(c) The principal occupation of Mr. Hendrickson is serving as the principal of Nokomis Capital. The principal business of Nokomis Capital

(f) Nokomis Capital is

As of April 4, 2017, the Nokomis Accounts had
invested $16,040,951.49 (inclusive of brokerage commissions) in the Common Stock of the Issuer. The source of these funds was the working capital of the Nokomis Accounts.

The Reporting Persons purchased the Common Stock for
the Nokomis Accounts based on the Reporting Persons belief that the Common Stock, when purchased, was undervalued and represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities
available to the Reporting Persons, and the availability of Common Stock at prices that would make the purchase or sale of Common Stock desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among
other things, the purchase or sale of Common Stock on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

The Reporting Persons have engaged, and intend to continue to engage, in discussions with the Issuers management and board of directors
(the Board) regarding the composition of the Board and senior management team as well as means to enhance stockholder value, including capital allocation, operational improvements and strategic alternatives.

No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) –
(j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. The Reporting Persons intend to review their investment in the
Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuers financial position and investment strategy, the price levels of the Common Stock, conditions in the securities markets and general economic
and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in communications with management and the Board of the
Issuer, engaging in discussions with stockholders of the Issuer and others about the Issuer and the Reporting Persons investment, making proposals to the Issuer concerning changes to the capitalization, ownership structure, board structure
(including board composition) or operations of the Issuer, purchasing additional Common Stock, selling some or all of their Common Stock, engaging in short selling of or any hedging or similar transaction with respect to the Common Stock, or
changing their intention with respect to any and all matters referred to in Item 4.

(a) The aggregate percentage of Common
Stock reported to be owned by the Reporting Persons is based upon 82,814,322 shares of Common Stock outstanding, which is the total number of shares of Common Stock outstanding as of March 30, 2017, as reported in the Issuers Form 10-K
filed with the Securities and Exchange Commission on March 30, 2017.

Nokomis Capital, as the investment adviser of the Nokomis
Accounts, may be deemed to beneficially own the 12,774,251 shares of Common Stock held by the Nokomis Accounts, representing approximately 15.4% of the issued and outstanding shares of Common Stock of the Issuer.

In addition, Mr. Hendrickson, as principal of Nokomis Capital, the investment adviser of the Nokomis Accounts, may also be deemed to
beneficially own the 12,774,251 shares of Common Stock beneficially owned by the Nokomis Accounts, representing approximately 15.4% of the issued and outstanding shares of Common Stock of the Issuer.

Nokomis Capital and Mr. Hendrickson disclaim beneficial ownership of the Common Stock held by the Nokomis Accounts except to the extent
of their pecuniary interest therein.

(b) Nokomis Capital and Mr. Hendrickson has the shared power to vote and dispose of the Common
Stock owned by the Nokomis Accounts reported in this Schedule 13D.

The filing of this Schedule 13D shall not be construed as admission
that Nokomis Capital or Mr. Hendrickson is, for the purposes of Section 13(d) or 13(g) of the Act, or otherwise, the beneficial owner of any of the 12,774,251 shares of Common Stock owned by the Nokomis Accounts. Pursuant to Rule 13d-4,
Nokomis Capital and Mr. Hendrickson disclaim all such beneficial ownership.

(c) There have been no transactions in the Common Stock
during the past sixty (60) days by the Reporting Persons.

to receive, or the power to direct the receipt of dividends from, or proceeds from the sale of, the Common Stock.
