Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions ( see General Instruction A.2. below):

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

Item 5.02(e). On March 29, 2011, the board of directors (the “Board”) of Union Drilling, Inc. (the “Company”) unanimously approved the form of Termination Protection Agreement (the “Agreement”) to be entered into between the Company and such senior executive officer of the Company as may be designated by the Board. The Agreement, among other things, provides:

The summary above does not purport to be complete and is qualified in its entirety by reference to the actual text of the Agreement filed as Exhibit 10.1 to this Current Report (being incorporated herein by reference).

Subsequent to its approval of the Agreement, the Board determined that the Company should enter into, as of March 30, 2011, such an Agreement with each of Mr. Christopher D. Strong, the Company’s President and Chief Executive Officer, Mr. David S. Goldberg, the Company’s Senior Vice President, General Counsel and Corporate Secretary, and Ms. Tina L. Castillo, the Company’s Senior Vice President, Chief Financial Officer and Treasurer.

On March 29, 2011, the Board also unanimously approved that the form of change of control provision for use in the Company’s officer stock option and officer restricted stock unit award agreements should be revised to add to the “Good Reason” definition a material change (60 miles or more) in the geographic location at which the officer must perform his/her services. Consequently, each outstanding equity award agreement between the Company and its corporate officers was amended by the Board to delete (i) the existing Section III.4.(v) of each stock option agreement and replace it with the complete text of the provision as set forth in Exhibit 10.2 (being incorporated herein by reference); and (ii) the existing Section 2.(g) of each restricted stock unit agreement and replace it with the complete text of the provision as set forth in Exhibit 10.3 (being incorporated herein by reference). Furthermore, the Board approved that the text as set forth in each of Exhibit 10.2 and 10.3 shall be the approved text for each change of control provision for any future equity award agreements between the Company and its corporate officers. As the Company has previously publicly filed its stockholder-approved form of stock option agreement and restricted stock unit agreement, only the respective language relating to the above-mentioned change of control provisions is being filed herewith.
