The MAC Group Syndicated Facility Agreement

Effective September 18, 2012, The MAC Services Group Pty Limited (the "Australian Borrower"), an Australian proprietary limited company and wholly owned subsidiary of Oil States International, Inc. ("Oil States"), entered into a AUD$300 million revolving loan facility governed by a Syndicated Facility Agreement (the "MAC Group Facility Agreement"), between the Australian Borrower, J.P. Morgan Australia Limited, as Australian agent and security trustee, JPMorgan Chase Bank, N.A., as U.S. agent, and the lenders party thereto. The MAC Group Facility Agreement replaces the Australian Borrower's existing AUD$150 million revolving loan facility.

Under the terms of the MAC Group Facility Agreement, loans bear interest for a particular interest period at a rate per annum equal to the sum of the average interest rate paid by banks for loans of the equivalent period and an applicable percentage ranging from 2.00% to 3.00% based upon the Australian Borrower's leverage ratio.

The MAC Group Facility Agreement contains representations, warranties and covenants that are customary for similar credit arrangements, including, among other things, covenants relating to financial reporting and notification, payment of obligations, and notification of certain events.

Financial covenants in the MAC Group Facility Agreement also require the Australian Borrower not to permit:

(i) the Interest Coverage Ratio (the ratio of Consolidated EBITDA to Consolidated Interest Expense) to be less than 4.0 to 1.0 for any period of four consecutive fiscal quarters of the Australian Borrower; and

(ii) the Leverage Ratio (the ratio of Total Debt to Consolidated EBITDA) to be greater than 3.0 to 1.0 for any period of four consecutive fiscal quarters of the Australian Borrower.

The MAC Group Facility Agreement contains various customary restrictive covenants, subject to certain exceptions, that prohibit the Australian Borrower and its subsidiaries from, among other things, incurring additional indebtedness or guarantees, creating liens or other encumbrances on property, entering into a merger or similar transaction, selling or transferring certain property, making certain restricted payments and entering into transactions with affiliates.

The failure to comply with the foregoing covenants will constitute an event of default (subject, in the case of certain covenants, to applicable notice and/or cure periods) under the MAC Group Facility Agreement. Other events of default under the MAC Group Facility Agreement include, among other things, the failure to timely pay principal or interest, the inaccuracy of representations or warranties in any material respect, the occurrence of certain bankruptcy or insolvency events and the occurrence of an event of default under the Credit Agreement (as defined below). The occurrence and continuance of an event of default could result in, among other things, termination of the lender's commitment and acceleration of all amounts outstanding. The Australian Borrower's obligations under the MAC Group Facility Agreement are guaranteed by certain of the Australian Borrower's subsidiaries, as well as Oil States. In addition, the Australian Borrower's obligations under the MAC Group Facility Agreement, subject to certain exceptions, are secured on a first-priority basis by liens on substantially all of the material personal property of the Australian Borrower and the Australian Borrower's subsidiaries.

A copy of the MAC Group Facility Agreement is attached hereto as Exhibit 10.1 and is incorporated herein by reference. The foregoing summary description of the MAC Group Facility Agreement is qualified in its entirety by reference to the MAC Group Facility Agreement filed as Exhibit 10.1.
