Item 5.01. Changes in Control of Registrant

On December 22, 2010, pursuant to the terms of an Agreement and Plan of Merger (the “Merger Agreement”) by and among NightHawk Radiology Holdings, Inc., a Delaware corporation (the “Company”), Virtual Radiologic Corporation, a Delaware corporation (“vRad”), and Eagle Merger Sub Corporation (“Merger Sub”), a Delaware corporation and a wholly-owned subsidiary of vRad, vRad completed its acquisition of the Company via the merger of Merger Sub with and into the Company, with the Company continuing as the surviving corporation in the merger and becoming a wholly-owned subsidiary of vRad (the “Merger”). The Merger Agreement and the transactions contemplated thereby, including the Merger, were approved by the Company’s board of directors and its stockholders. The Company stockholders approved the Merger Agreement at a special meeting of the Company stockholders held on December 22, 2010.

At the effective time and as a result of the Merger, each share of common stock of the Company issued and outstanding immediately prior to the effective time of the Merger (other than shares owned by vRad, Merger Sub and their affiliates, stockholders who have perfected and not withdrawn a demand for appraisal rights under Delaware law) was converted into the right to receive $6.50 in cash, without interest. In addition, outstanding options vested in full, were canceled immediately prior to the effective time, and each option holder received, with respect to each canceled option, the amount by which the $6.50 per share merger consideration exceeded the option exercise price, without interest and less any applicable withholding for taxes.

The foregoing summary does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which is included as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by this reference.

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

In connection with the completion of the Merger, the Company notified the NASDAQ Stock Market on December 22, 2010 that the Merger has been completed, and has been advised that trading of Company common stock on the NASDAQ Global Market will be suspended. The Company intends to file a certification on Form 15 requesting that the Company’s reporting obligations under Sections 13 and 15(d) of the Securities Exchange Act of 1934, as amended, be suspended.

Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

On December 22, 2010, at the effective time of the Merger, each of Charles Bland, David Engert, Peter Chung, David Brophy and Jeff Terrill, who constituted the board of directors of the Company prior to the Merger (the “Prior Directors”), resigned from their directorships of the Company and from all committees of which they were members. The resignation of the Prior Directors did not result from any disagreements with the Company regarding any matter related to the Company’s operations, policies or practices. Immediately following the resignation of the Prior Directors and pursuant to the Merger Agreement, at the effective time of the Merger on December 22, 2010, the directors of Merger Sub immediately prior to the effective time of the Merger became the directors of the Company. In addition, pursuant to the terms of the Merger Agreement, at the effective time of the Merger, the officers of Merger Sub immediately prior to the effective time of the Merger became the officers of the Company.

Pursuant to the terms of the Merger Agreement, at the effective time of the Merger on December 22, 2010, the Certificate of Incorporation of the Company was amended and restated. Pursuant to the terms of the Merger Agreement, at the effective time of the Merger on December 22, 2010, the bylaws of Merger Sub as in effect at the Effective Time became the bylaws of the Company.
