	$60,000,000.00	 	October 14, 2005

  
 FOR VALUE
RECEIVED, the undersigned, Bronco Drilling Company, Inc., a Delaware corporation (the “Borrower”), with an address at 14313 North May Avenue, Oklahoma City, Oklahoma 73134, hereby promises and agrees to pay to the order of Theta
Investors LLC, a Delaware limited liability company, with its main office located at c/o Wexford Capital LLC, 411 West Putnam Avenue, Greenwich, Connecticut 06830 (herein called the “Lender”) the principal sum of SIXTY MILLION
DOLLARS ($60,000,000), or so much thereof as may be advanced and remain unpaid hereunder, in lawful money of the United States of America and in immediately available funds together with all accrued interest thereon computed and payable in the
manner set forth below. The unpaid principal balance of, and all accrued interest on, this Note, unless sooner paid, shall be due and payable in full on the first anniversary of the date hereof or on such earlier date as provided herein (the
“Maturity Date”). 
  
 1. Payments.
Interest shall be payable monthly in arrears on the 15th day of each month commencing November 15, 2005 and on
maturity. The interest rate applicable at any time to the outstanding balance of the Note is herein referred to as the “Borrowing Rate”. From the date of this Note until December 31, 2005, the outstanding principal balance of
this Note, as the same shall exist from time to time, shall bear interest at the Borrowing Rate equal to LIBOR plus four hundred basis points (LIBOR + 4%); thereafter until the Maturity Date, the Borrowing Rate shall be LIBOR plus six hundred basis
points (LIBOR + 6%). All interest on this note shall be computed on the actual number of days elapsed over a three hundred sixty (360) day year. For purposes of this Note, LIBOR shall be the thirty (30) day Libor rate, determined as of
October 14, 2005 and on the 15th day of each month thereafter, commencing November 15, 2005, so long as
the Note remains outstanding. 
  
 2. Payments of principal and
interest of this Note are to be made in lawful money of the United States of America at the office of the Lender or at such other place as the Lender shall have designated by written notice to the Borrower. 
  
 If any installment of interest or principal on this Note is not paid by the
end of ten (10) calendar days after the date it is due, the Lender may, at any time thereafter, increase the interest rate applicable to the outstanding principal balance of this Note to a rate which is two percent (2%) in excess of the
Borrowing Rate specified above otherwise applicable to the principal of this Note (the “Default Rate”). The assessment or collection of Default Rate interest shall not constitute a waiver of any default resulting from any failure to
timely pay any payment due pursuant to this Note. In no event shall the applicable rate hereunder exceed the maximum rate of interest, if any, which may be collected from the undersigned under applicable law. In the event that any payment received
by the Lender shall be deemed in excess of the maximum legal rate of interest, then the dollar amount of any interest overpayment, over and above the maximum legal interest rate collectible by the Lender, shall be credited against the outstanding
principal balance hereof. The Default Rate shall apply retroactively to the first such Event of Default and shall continue until all such Events of Default have been cured. 







 3. Advances. The Lender agrees to make advances to the Borrower at any time and from time to time
after the date hereof up to Sixty Million Dollars ($60,000,000). Such periodic advances shall be made upon two (2) business days’ prior written request by the Borrower. Each advance shall bear interest from the date of the advance at the
rate prescribed in this Note and shall otherwise be subject to all terms and conditions expressed herein. Each borrowing shall be in minimum multiples of One Million Dollars ($1,000,000). All borrowings under and all payments made on account of
principal or interest on this Note shall be endorsed by Lender on the grid attached hereto as ANNEX I which is part of this Note and shall constitute prima facie evidence of the accuracy of the information endorsed. 
  
 4. Prepayment. The Borrower may prepay this Note, in whole or in part,
at any time and from time to time without penalty. Each such prepayment shall be accompanied by all accrued but unpaid interest to the date of prepayment. All payments shall be applied first to accrued and unpaid interest and then to principal.

  
 5. Restrictions on Business; Indebtedness. Except as
expressly permitted hereby, during the term of this Note, without the Lender’s prior written consent, the Borrower will not, directly or indirectly:
