9% SENIOR NOTES DUE 2019

Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

(1)         INTEREST.  Forbes Energy Services Ltd., a Bermuda exempt company ( the “Issuer”), promises to pay interest on the principal amount of this Note at a rate of 9% per annum, from June 7, 2011 until maturity. The Issuer will pay interest semi-annually in arrears on June 15 and December 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof (each, a “Record Date”) and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be December 15, 2011. The Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal, premium, if any, and interest (without regard to any applicable grace period), from time to time on demand at a rate equal to 2% per annum in excess of the then applicable interest rate on the Notes to the extent lawful. The Issuer will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuer will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the expense of the Issuer) will mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. The Issuer will pay Additional Interest, if any, to Holders of Notes pursuant to the Registration Rights Agreement. Defaulted interest and Additional Interest, if any, will be paid on regular Interest Payment Dates in the same manner as other interest is paid on the Notes. All reference to “interest” in this Note and the Indenture mean the initial interest rate borne by the Notes and any increases in that rate due to defaulted interest or Additional Interest (unless the Indenture states otherwise). Defaulted interest and Additional Interest will be in addition to any other interest payable from time to time with respect to the Notes. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

(2)         METHOD OF PAYMENT.  The Issuer will pay interest on the Notes (except defaulted interest) to the Persons who are Holders at the close of business on June 1 or December 1 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Sections 2.12 and 6.01 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Issuer maintained for such purpose, or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that (1) payment by wire transfer of immediately available funds will be required with respect to principal of, interest and premium, if any, on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Issuer or the Paying Agent and (2) such payment by check may only be paid so long as no event of default under the Indenture is continuing. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. The principal of

the Notes shall be payable only upon surrender of any Note at the specified offices of the Paying Agent. If the due date for payment of the principal in respect of any Note is not a Business Day at the place in which it is presented for payment, the Holder thereof shall not be entitled to payment of the amount due until the next succeeding Business Day at such place.

(3)         PAYING AGENT AND REGISTRAR.  Initially, Wells Fargo Bank, National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer or any of its Subsidiaries may act in any such capacity; provided no Event of Default is continuing.

(4)         INDENTURE; REGISTRATION RIGHTS AGREEMENT.  The Issuer issued the Notes under an Indenture dated as of June 7, 2011 (the “Indenture”) among the Issuer, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, which applies to the Indenture and is incorporated by reference therein. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are unsecured obligations of the Issuer. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder. Holders are entitled to the benefits of the Registration Rights Agreement.

Within 10 days following any Change of Control or, at the Issuer’ option, prior to such Change of Control but after public announcement thereof, the Issuer will mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture.

(b) If the Issuer or a Restricted Subsidiary of the Issuer consummates an Asset Sale, the Issuer in circumstances specified in the Indenture may be required to commence an offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in the Indenture with

The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Issuer need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part.

Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest or premium, if any,) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest or premium, if any, on, or the principal of, the Notes.

Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.
