Second Amendment to Allis-Chalmers
Energy Second Amended and
Restated Credit Agreement

“Applicable Rate means the following percentages per annum set forth in the table below, on any date of determination, with respect to the Type of Credit Extension or commitment fee that corresponds to the Leverage Ratio at such date of determination, as calculated based on the quarterly Compliance Certificate most recently delivered pursuant to Section 6.02(a):

						Commitment				Letter of Credit
Pricing						Fee				and Eurodollar Rate				Base Rate
Level				Leverage Ratio		+ (basis points)				+ (basis points)				+ (basis points)
	1			Less than 2.50:1.00			75.0				400.0				300.0
	2			Less than 3.00:1.00 but greater than or equal to 2.50:1.00			85.0				425.0				325.0
	3			Less than 3.50:1.00 but greater than or equal to 3.00:1.00			95.0				500.0				400.0
	4			Greater than or equal to 3.50:1.00			105.0				650.0				550.0

Any increase or decrease in the Applicable Rate resulting from a change in the Leverage Ratio shall become effective as of the first day of the fiscal quarter of the Borrower immediately following the date of a Compliance Certificate delivered pursuant to Section 6.02(a); provided, however, that if no Compliance Certificate is delivered during a fiscal quarter within 10 days after such Compliance Certificate is due in accordance with such Section, Pricing Level 4 shall apply as of the first day of such following fiscal quarter.

In the event that any Compliance Certificate delivered hereunder is shown to be inaccurate (regardless of whether this Agreement or the Aggregate Revolving Commitment is in effect when such inaccuracy is discovered), and such inaccuracy, if corrected, would have led to the application of a higher Applicable Rate based upon the foregoing pricing grid (the “Accurate Applicable Rate”) for any period that such Compliance Certificate covered, then (i) the Borrower shall immediately deliver to the Administrative Agent a Compliance Certificate for such period, (ii) the Applicable Rate shall be adjusted such that after giving effect to the corrected Compliance Certificate the Applicable Rate shall be reset to the Accurate Applicable Rate based upon the foregoing pricing grid for such period as set forth in the foregoing pricing grid and (iii) if the Accurate Applicable Rate is higher than the Applicable Rate based upon the foregoing pricing grid, the Borrower shall immediately pay to the Administrative Agent, for the account of the Lenders, the accrued additional interest owing as a result of such Accurate Applicable Rate for such period.”

“Base Rate means for any day a fluctuating rate per annum equal to the highest of (a) the Federal Funds Rate plus ¹/2 of 1%, (b) the Prime Rate for such day, and (c) the Eurodollar Rate for a one-month Interest Period on such day (or if such day is not a Business Day, the immediately preceding Business Day) plus one and one-quarter percent (1.25%); provided that, for the avoidance of doubt, the Eurodollar Rate for any day shall be based on the rate appearing on the LIBOR I screen (or any successor thereto) that displays an average British Bankers Association Interest Settlement Rate for deposits in Dollars at approximately 11:00 a.m. (London time) on such day. Any change in the Base Rate due to a change in the Prime Rate, Federal Funds Rate or the Eurodollar Rate shall be effective automatically and without notice to Borrower or any Lender on the effective date of such change in the Prime Rate, Federal Funds Rate or Eurodollar Rate, respectively.”

Second Amendment to Allis-Chalmers

(b) if the rate referenced in the preceding subsection (a) is not available, the rate per annum determined by the Administrative Agent as the rate of interest (rounded upward to the next 1/100th of 1%) at which deposits in Dollars for delivery on the first day of such Interest Period in same day funds in the approximate amount of the Eurodollar Rate Loan being made, continued or converted by the Administrative Agent and with a term equivalent to such Interest Period would be offered by the Administrative Agent’s London Branch to major banks in the offshore Dollar market at their request at approximately 11:00 a.m. (London time) two Business Days prior to the first day of such Interest Period.”

“Prime Rate means for any day, the rate of interest in effect for such day as publicly announced from time to time by the Administrative Agent as its “prime rate.” Such rate is a rate set by the Administrative Agent based upon various factors including the Administrative Agent’s costs and desired return, general economic conditions and other factors, and is used as a reference point for pricing some loans, which may be priced at, above, or below such announced rate.”
