Item 3.01 Notice of Delisting or Failure to Satisfy a Continuing Listing Rule or Standard; Transfer of Listing.

On January 5, 2010, Quest Resource Corporation (the “Company”) received a determination letter (the “Determination Letter”), which the Company expected, from The NASDAQ Stock Market (“NASDAQ”) stating that the Company’s common stock is subject to delisting since the Company failed to hold the required 2009 annual meeting of stockholders by December 31, 2009, and therefore was not in compliance with NASDAQ Listing Rules 5620(a) and 5620(b).

In the Determination Letter, NASDAQ advised that the Company may request an appeal of this determination by making a hearing request to the NASDAQ Listing Qualifications Hearings Panel, which will stay the suspension of the Company’s securities and the filing of a Form 25-NSE with the Securities and Exchange Commission (the “SEC”). The request for a hearing must be received by NASDAQ by January 12, 2010, and the Company intends to timely submit such a request.

The Company delayed the 2009 annual meeting in order to reduce costs by combining the 2009 annual meeting with the stockholder meeting to vote on the proposed recombination of the Company with Quest Midstream Partners, L.P. (“Quest Midstream”) and Quest Energy Partners, L.P. (“Quest Energy”), which is discussed below and in Amendment No. 1 to PostRock Energy Corporation’s (“PostRock”) registration statement on Form S-4/A that was filed with the SEC on December 17, 2009. The Company intends to hold the 2009 annual meeting, which will include the stockholder vote on the proposed recombination, promptly after the SEC completes its review and declares the registration statement effective.

A copy of the press release announcing receipt of the Determination Letter is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

Additional Information and Where to Find It

Pursuant to the Agreement and Plan of Merger, dated as of July 2, 2009, as amended (the “Merger Agreement”), by and among the Company, Quest Midstream, Quest Energy and the other parties listed on the signature pages thereto, the entities have agreed to form PostRock as a new, publicly-traded corporation that, through a series of mergers and entity conversions, would wholly-own all three entities (the “Recombination”). In connection with the proposed Recombination, PostRock filed an amended registration statement on Form S-4/A with the SEC on December 17, 2009. The registration statement covers the shares of PostRock common stock to be issued to the Company’s stockholders, Quest Energy common unitholders (other than the Company) and Quest Midstream common unitholders at the completion of the Recombination and includes a preliminary joint proxy statement/prospectus. INVESTORS ARE URGED TO CAREFULLY READ THE REGISTRATION STATEMENT AND THE DEFINITIVE JOINT PROXY STATEMENT/PROSPECTUS AND OTHER DOCUMENTS FILED WITH THE SEC REGARDING THE TRANSACTION CONTEMPLATED BY THE MERGER AGREEMENT WHEN THEY BECOME AVAILABLE, BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT THE PARTIES TO THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT.
