 11% SENIOR SECURED NOTE DUE 2015 

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

 (1) INTEREST. Forbes Energy Services LLC, a Delaware limited liability company and
Forbes Energy Capital Inc., a Delaware corporation (collectively, the “Issuers”), promise to pay interest on the principal amount of this Note at a rate of 11% per annum, from February 12, 2008 until maturity. The Issuers
will pay interest semi-annually in arrears on February 15 and August 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 August 15, 2008. The Issuers 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 Issuers 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 Issuers 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 Issuers (or, upon the written request of the Issuers, the Trustee in the name and at the expense of the Issuers) 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 Issuers 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 Issuers will pay interest on the Notes (except defaulted interest) to the Persons who are Holders at the close
of business on February 1 or August 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 Section 2.12 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 Issuers maintained for such purpose, or, at the option of the Issuers, 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 Issuers 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 Issuers may change any Paying Agent or Registrar without notice to any
Holder. The Issuers or any of their Subsidiaries may act in any such capacity; provided no Event of Default is continuing. 

(4) INDENTURE; REGISTRATION RIGHTS AGREEMENT AND
COLLATERAL AGREEMENT. The Issuers issued the Notes under an Indenture dated as of February 12, 2008 (the “Indenture”) among the Issuers, 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 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 and the Collateral Agreements. 

(5) RANKING. This Note shall constitute a senior obligation of the Issuers and the Obligations of
the Issuers under the Indenture and this Note shall be secured pursuant to the Collateral Documents and will be subject to the Intercreditor Agreement, if any. 
 (6) OPTIONAL REDEMPTION AND PURCHASE. The Notes are subject to redemption and purchase as provided in Article III of the
Indenture. 
 (7) MANDATORY REDEMPTION. The Issuers are not required to make
mandatory redemption or sinking fund payments with respect to the Notes. 
 (8) REPURCHASE AT
THE OPTION OF HOLDER. 
 (a) If
there is a Change of Control, the Issuers will be required to make a Change of Control Offer to each Holder to repurchase all or any part (equal to minimum amounts of $2,000 and integral multiples of $1,000) of each Holder’s Notes at a purchase
price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest
due on the relevant interest payment date (the “Change of Control Payment”). Within 10 days following any Change of Control or, at the Issuers’ option, prior to such Change of Control but after public announcement thereof, the
Issuers 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 Issuers or a Restricted Subsidiary of the Issuers consummates an Asset Sale, the Issuers 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 respect to offers to purchase or redeem with the proceeds of sales of assets an Asset Sale Offer
pursuant to Section 3.09 of the Indenture to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of
the principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of purchase, in accordance with the procedures set forth in the Indenture. Holders of Notes that are the subject of an offer to
purchase will receive an Asset Sale Offer from the Issuers prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes.

 (c) If any New Parent and its Restricted Subsidiaries or the Company and its
Restricted Subsidiaries has Excess Cash Flow for any fiscal year commencing with the fiscal year ending December 31, 2008, each Holder will have the right to require the Issuers to repurchase all or any part of that Holder’s Notes (in
minimum amounts of $2,000 and integral multiples of $1,000) at a purchase price in cash equal to 101% of the principal amount of the Notes repurchased, plus any accrued and unpaid interest and Additional Interest, if any, to the date of purchase
(subject to the rights of Holders of Notes on the relevant Record Date to receive interest due on the relevant Interest Payment Date that is on or prior to the date of repurchase), with 50% of Excess Cash Flow of such New Parent and its Restricted
Subsidiaries or the Company and its Restricted Subsidiaries, in each case, on a consolidated basis for such fiscal year (less the amount of any open market purchases and any redemptions of Notes pursuant to the Indenture made during such fiscal
year). 
 (9) NOTICE OF REDEMPTION. Notice of redemption will
be mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the
notice is issued in connection with a defeasance of the Notes or a satisfaction or discharge of the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a
Holder are to be redeemed. 
 (10) DENOMINATIONS, TRANSFER,
EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the
Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuers may require a Holder to pay any taxes and fees required by law or permitted by the
Indenture. The Issuers 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. Also, the Issuers need not exchange or register the
transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date. 

(11) PERSONS DEEMED OWNERS. The Holder of a Note may be treated as its
owner for all purposes. Only Holders have rights under the Indenture and this Note. 
 (12) AMENDMENT,
SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture, the Notes or the Note Guarantees may be amended or supplemented with the consent of the Holders of at least a
majority in aggregate principal amount of the then outstanding Notes, voting as a single class, and any existing Default or Event or Default or compliance with any provision of the Indenture, the Notes or the Note Guarantees may be waived with the
consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes, voting as a single class. Without the consent of any Holder of a Note, the Indenture, the Notes or the Note Guarantees may be amended or supplemented
to cure any ambiguity, defect or inconsistency and to effect certain other changes as set forth in the Indenture. 
 (13)
DEFAULTS AND REMEDIES. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without
further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. 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. The Issuers are required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Issuers are required, upon becoming aware of any
Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 
 (14)
TRUSTEE DEALINGS WITH THE ISSUERS. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services
for the Issuers or their Affiliates, and may otherwise deal with the Issuers or their Affiliates, as if it were not the Trustee. 
 (15) NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator or equity holder of any New Parent, the
Company, Capital or any Guarantor, as such, will have any liability for any obligations of any New Parent, the Company, Capital or the Guarantors under the Notes, the Indenture or the Note Guarantees or for any claim based on, in respect of, or by
reason of, such obligations or their creation. 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. 

(16) AUTHENTICATION. This Note will not be valid until authenticated by the manual signature of the
Trustee or an authenticating agent.
