     THIS  AMENDMENT  NO.  11  (this  "Agreement") is entered into as of June 4,
2010,  by and among BEST ENERGY SERVICES, INC (f/k/a HYBROOK RESOURCES CORP.), a
corporation organized under the laws of the State of Nevada ("Best"), BOB BEEMAN
DRILLING  COMPANY,  a  corporation organized under the laws of the State of Utah
("BBD")  and  BEST WELL SERVICE, INC., a corporation organized under the laws of
the  State  of  Kansas  ("BWS")  (Best,  BBD  and  BWS,  each  a "Borrower", and
collectively  "Borrowers"),  the  financial  institutions  party  hereto
(collectively, the "Lenders" and individually a "Lender") and PNC BANK, NATIONAL
ASSOCIATION  ("PNC"), as agent for Lenders (PNC, in such capacity, the "Agent").

                                   BACKGROUND

Borrowers,  Lenders and Agent are parties to that certain Revolving Credit, Term
Loan and Security Agreement dated as of February 14, 2008 (as amended, restated,
supplemented  or  otherwise  modified  from  time to time, the "Loan Agreement")
pursuant  to  which  Agent  and Lenders provide Borrowers with certain financial
accommodations.

Borrowers  have requested that Agent and Lenders amend certain provisions of the
Loan Agreement as hereafter provided, and Agent and Lenders are willing to do so
on  the  terms  and  conditions  hereafter  set  forth.

NOW,  THEREFORE,  in  consideration  of  any  loan or advance or grant of credit
heretfore  or  hereafter  made  to  or  for the account of Borrowers by Agent or
Lenders,  and  for  other  good  and  valuable  consideration,  the  receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as
follows:

1.     Definitions.  All  capitalized  terms  not  otherwise  defined or amended
herein  shall  have  the  meanings  given  to  them  in  the  Loan  Agreement.

2.     Reservation  of  Rights: Borrowers acknowledge that the Events of Default
set  forth  on  Schedule  I  hereto (collectively, the "Existing Defaults") have
occurred  and  are  continuing  under  the  Loan  Agreement.

     (a) As a result of the Existing Defaults, Agent has the immediate right to
     exercise its rights and remedies under the Loan Agreement, the Other
     Documents or at law.

     (b) To the extent Agent makes any additional Advances after the date
     hereof, such Advances shall not constitute either a waiver of, nor
     agreement to forbear by Agent with respect to the Existing Defaults or any
     future violation or Event of Default under the Loan Agreement or the Other
     Documents, including, without limitation, the Existing Defaults. No such
     additional Advances by Agent shall, directly or indirectly, in any way
     whatsoever, impair, prejudice or otherwise adversely effect Agent's right
     at any time and from time to time to exercise any right, privilege or
     remedy in connection with the Loan Agreement or related documents or amend
     or alter the provisions of the Loan Agreement or the Other Documents or

<PAGE>
     constitute a course of dealing or other basis for altering any Obligation
     of Borrowers or any other Person or any right, privilege or remedy of Agent
     under the Loan Agreement or the Other Documents.

     (c) Although Agent is not presently taking any immediate action with
     respect to the Existing Defaults except as set forth above, Agent hereby
     reserves all its rights and remedies under the Loan Agreement, the Other
     Documents and applicable law, and its election not to exercise any such
     right or remedy at the present time shall not (a) preclude Agent from
     ceasing at any time to make Advances, (b) limit in any manner whatsoever
     Borrowers' obligation to comply with, and Agent's right to insist on
     Borrowers' compliance with, each and every term of the Loan Agreement and
     the Other Documents or (c) constitute a waiver of any Event of Default or
     any right or remedy available to Agent under the Loan Agreement, the Other
     Documents or applicable law, and Agent hereby expressly reserves its rights
     with respect to the same.

     (d) No failure or delay on the part of Agent in exercising any right or
     remedy under the Loan Agreement and no course of dealing between Borrowers
     and Agent shall operate as a waiver of any such right or remedy nor shall
     any single or partial exercise of any right or remedy under the Loan
     Agreement preclude any other or further exercise thereof or the exercise of
     any other right or remedy under the Loan Agreement. Agent expressly
     reserves all of its rights and remedies under the Loan Agreement.

3.     Amendments  to  Loan Agreement.  Subject to the satisfaction of Section 4
below,  and  effective  as of June 1, 2010, Section 2.4 of the Loan Agreement is
hereby  amended  by amending and restating the third sentence thereof to read in

2009, (b) $125,000 per month, from January 1, 2010 through December 31, 2010
(provided, however, that the Term Loan payment with respect to the months of
May, 2010 and June, 2010 shall be in the amount of $50,000 payable on May 3,
2010 and June 1, 2010, respectively), and (c) $150,000 per month thereafter,
with the balance payable upon expiration of the Term, subject to acceleration
upon the occurrence of an Event of Default under this Agreement or termination
of this Agreement."

remedies under the Loan Agreement and the Other Documents.  Accordingly, for and

indirect, and of whatever nature or description, and whether in law or in
equity, under contract, tort, statute or otherwise, which any Releasor has
heretofore had or now or hereafter can, shall or may have against any Released
Party by reason of any act, omission or thing whatsoever done or omitted to be
done on or prior to the date hereof arising out of, connected with or related in
any way to this Agreement, the Loan Agreement or any Other Document, or any act,
event or transaction related or attendant thereto, or Agent's or any Lender's
agreements contained therein, or the possession, use, operation or control of
any of the assets of agreements contained therein, or the possession, use,
operation or control of any of the assets of the Borrowers, or the making of any
advance, or the management of such advance or the Collateral.

     8.     Governing  Law.  This  Agreement  shall be binding upon and inure to
the  benefit  of  the parties hereto and their respective successors and assigns
and  shall be governed by and construed in accordance with the laws of the State
of  New  York  (other  than  those conflict of law rules that would defer to the
substantive  law  of  another  jurisdiction).

9.     Cost  and Expenses.   Borrowers hereby agree to pay the Agent, on demand,
all  costs  and  reasonable  expenses  (including reasonable attorneys' fees and
legal  expenses)  incurred in connection with this Agreement and any instruments
or  documents  contemplated  hereunder.

10.     Headings.  Section  headings  in  this Agreement are included herein for
convenience  of reference only and shall not constitute a part of this Agreement
for  any  other  purpose.

11.     Counterparts;  Facsimile  Signatures.  This Agreement may be executed by
