      to
      the original amount owing on a Receivable in accordance with its customary
      and
      commercially reasonable credit policies and collection practices in effect

        against
        such risks and casualties, in such amounts and with such insurers as required
        by
        the Note. Such insurance policy shall (i) contain a loss payable clause and
        a

    (b) If
      Grantor fails to obtain and keep in full force and effect the insurance coverage
      required by the Note or fails to pay the premiums therefor when due, Trustee
      may
      (but shall not be obligated to) do so for the account of Grantor (without
      waiving or releasing any obligation or default of Grantor hereunder), and the
      cost thereof shall be added to the Secured Obligations and shall be payable
      upon
      demand with interest accruing thereon at the Default interest rate provided
      from

    13. Rights
      in Collateral.

     

    (a) Other
      than the liens set forth on Schedule
      VI,
      Grantor
      represents, warrants and covenants that it has and shall have at all times
      valid
      title to all Collateral, free and clear of all liens, claims, charges and
      encumbrances (except for Permitted Liens), and Grantor shall defend such title
      against the claims and demands of all other Persons. Other than for the Stock
      Rights, vehicles and bank accounts, Grantor represents and warrants that this
      Agreement creates a valid security interest in the Collateral which, upon filing
      of proper financing statements in the jurisdictions and the taking of all other
      steps regarding perfection specified on Schedule
      VII
      attached
      hereto, shall constitute a valid perfected lien on and security interest in
      the
      Collateral, subject only to Permitted Liens which are accorded priority. Grantor
      represents and warrants that to the best of Grantor’s knowledge, except as
      previously disclosed, all Receivables are valid, binding and enforceable in
      accordance with their respective terms and that no party to any Receivable
      is in
      default with respect thereto, except to the extent of allowances for
      uncollectible accounts reflected on the financial statements of Grantor in
      accordance with generally accepted accounting principles consistently
      applied.

     

    (b) Except
      for dispositions permitted by the Indenture or in the ordinary course of
      business, Grantor shall not sell, transfer, assign, convey or otherwise dispose
      of, or extend, amend, terminate or otherwise modify any term or provision of,
      any Collateral, any interest therein or any Proceeds thereof, nor waive or
      release any right with respect thereto, without, the prior written consent
      of
      Trustee.

     

    (c) Grantor
      assumes full responsibility for taking any and all steps to preserve its rights
      with respect to the Collateral against all prior parties. Trustee shall be
      deemed to have exercised reasonable care in the preservation and custody of
      the
      portion of the Collateral as may be in Trustee’s possession if Trustee takes
      such action as is required by applicable law and as Grantor shall reasonably
      request in writing; provided that such requested action shall not, in the
      judgment of Trustee, impair Trustee’s prior security interest in such Collateral
      or its rights in or the value of such Collateral, and provided further that
      such
      written request is received by Trustee in sufficient time to permit Trustee
      to
      take the requested action. In the absence of such written request, Trustee
      shall
      be deemed to have exercised reasonable care in the custody and preservation
      of
      the Collateral in its possession if the Collateral is accorded treatment
      substantially equal to that which Trustee accords its own property.

      14. Records.
        With
        respect to Collateral in which it has rights or interests, Grantor shall
        at all
        times maintain accurate and complete records with respect to each item of
        Collateral constituting fixed assets, shall keep aggregate records regarding
        Inventory or Receivables, and shall otherwise keep books and records in
        accordance with the terms of the Indenture.

    

     

    15. Taxes
      and Charges.
      Grantor
      shall pay and discharge all taxes, levies and other impositions levied on any
      Collateral in which Grantor has rights or interests, in accordance with the
      terms of the Indenture, unless such failure to pay would not have a material
      adverse effect on the market value of the Collateral or if Grantor contest
      such
      tax, levy or imposition. If Grantor shall fail to do so, Trustee may (but shall
      not be obligated to) pay such taxes, levies or impositions for the account
      of
      Grantor (without waiving or releasing any obligation or default by Grantor
      hereunder), and the amount thereof shall be added to the Secured Obligations
      and
      shall be payable upon demand with interest accruing at the Default Interest
      Rate.

     

    16. Preservation
      and Protection of Security Interest.
      Except
      as otherwise provided herein, Grantor shall use its best efforts to diligently
      preserve and protect Trustee’s security interest in the Collateral in which
      Grantor has rights or interests and Borrower shall, at its expense, cause such
      security interest in such Collateral, other than the, vehicles and bank accounts
      (until required herein) owned by the Borrower to be perfected and continue
      perfected so long as the Secured Obligations or any portion thereof are
      outstanding
      and
      unpaid (including, without limitation, by means of the delivery of all
      instruments, documents of title and securities to Trustee with endorsements
      and
      documents of transfer satisfactory to Trustee), and for such purposes, Grantor
      shall from time to time at Trustee’s request and at its expense file or record,
      or cause to be filed or recorded, such instruments, documents and notices
      (including, without limitation, financing statements and continuation
      statements) as Trustee may deem necessary or advisable from time to time to
      perfect and continue perfected such security interests during the period, in
      accordance with the foregoing provision, that each Grantor has the obligation
      to
      cause such security interest to be perfected. Grantor shall do all such other
      acts and things and shall execute and deliver all such other instruments and
      documents (including, without limitation, further security agreements, pledge
      agreements, pledges, endorsements, assignments and notices) as Trustee may
      deem
      necessary or advisable from time to time to perfect and preserve the priority
      of
      Trustee’s security interest in the Collateral, as a perfected security interest
      in the Collateral (except as otherwise provided herein), prior to the rights
      of
      any other secured party or lien creditor, except with respect to Permitted
      Liens, which are accorded priority or as contemplated in the Intercreditor
      Agreement. Trustee, and its officers, employees and authorized agents, or any
      of
      them, are hereby irrevocably appointed the attorneys-in-fact of Grantor to
      do,
      at Grantor’s expense, all acts and things which Trustee may deem necessary or
      advisable to preserve, perfect and continue perfected Trustee’s security
      interest in the Collateral (including, without limitation, the signing of
      financing, continuation or other similar statements and notices on behalf of
      Grantor), which appointment is irrevocable and coupled with an interest.

      17. Federal
        Claims.
        Grantor
        shall notify Trustee of any Collateral which constitutes a claim against
        the
        United States government or any instrumentality or agency thereof, the
        assignment of which claim is governed by federal law. Upon the request of
        Trustee, Grantor shall at its expense take all actions required to comply,
        to
        Trustee’s satisfaction, with the Assignment of Claims Act of 1940, as amended,
        or any similar applicable law, with respect to any such Collateral having
        a
        value in excess of $10,000.

       

      18. Intercreditor
        Agreement.
        The
        Trustee hereby acknowledges and agrees that the exercise of remedies pursuant
        to
        paragraph 19 hereof and all other provisions of this Agreement are, and shall
        at
        all times be, subject to the limitations on the Trustee’s remedies set forth in
        the Intercreditor Agreement.

    

     

    19. Remedies
      on Default.
      Subject
      to the terms and conditions set forth in the Intercreditor
      Agreement:

     

    (a) If
      any
      Event of Default shall occur and be continuing or shall exist, Trustee may
      (i)
      to the full extent permitted by law, take possession and control of all or
      any
      part of the Collateral and Proceeds thereof and the books and records pertaining
      thereto, with or without judicial process, and (ii) after ten days prior written
      notice, proceed to exercise one or more of the rights and remedies accorded
      to a
      secured party by the UCC and otherwise by law or by the terms of the Indenture
      or this Agreement. Trustee’s rights and remedies shall include, without
      limitation, the power to (i) sell, lease, assign or otherwise dispose of and
      deliver all or any portion of the Collateral at public or private sale or sales
      at such place and time and on such terms as Trustee may see fit (subject to
      the
      requirements, including commercial reasonableness, of applicable law), (ii)
      endorse in the name of Grantor any Instrument representing Collateral, (iii)
      prosecute claims and legal actions regarding Accounts, other Receivables and
      General Intangibles, (iv) perform any agreement or contract which constitutes
      Collateral and (v) sell, assign, license, sublicense or otherwise dispose of,
      all right, title and interest in and to any General Intangibles included in
      the
      Collateral (including, without limitation, assignments, recordings,
      registrations and applications therefor in the United States Patent and
      Trademark Office, the United States Copyright Office or any similar domestic
      or
      foreign office or agency) and for the purpose of recording, registering and
      filing of, or accomplishing any other formality with respect to the foregoing,
      execute and deliver any and all agreements, documents, instruments of assignment
      or other papers necessary or advisable to effect such purpose. Without
      precluding any other methods of sale, the sale of Collateral shall be deemed
      to
      have been made in a commercially reasonable manner if conducted in conformity
      with reasonable commercial practices of secured lenders disposing of similar
      property, but in any event, Trustee may sell the Collateral on such terms as
      Trustee may choose without assuming any credit risk and without any obligation
      to advertise or give notice of any kind not expressly required under this
      Agreement or by the UCC or otherwise. All of the rights and remedies of Trustee
      under this Agreement shall be cumulative and not exclusive of other rights
      and
      remedies which it otherwise would have, whether under the Indenture, the UCC
      or
      otherwise. After the occurrence of an Event of Default, promptly upon the
      request of Trustee, Grantor shall assemble so much of the Collateral (including,
      without limitation, all books and records relating thereto) in its possession
      as
      is capable of physical delivery and make the same available to Trustee at such
      locations designated by Trustee reasonably convenient to both parties and shall
      permit Trustee, or Trustee’s representatives and agents, to enter any premises
      where all or any part of the Collateral, or the books and records relating
      thereto, or both, are located, to take possession of all or any part of the
      Collateral and to remove all or any part of the Collateral. The right of Trustee
      to have the Collateral assembled and made available to it is of the essence
      of
      this Agreement, and Trustee may, at its election, enforce such right by a bill
      in equity for injunctive relief for specific performance. Trustee shall not
      be
      under any obligation to marshal any assets in favor of Grantor or any other
      Person or against or in payment of all or any of the Secured
      Obligations.

    (b) Grantor
      agrees that in any sale of any of the Collateral, Trustee is authorized to
      comply with any limitation or restriction in connection with such sale which
      it
      is advised by its counsel is appropriate (i) to avoid violation of
      applicable law, or (ii) to obtain any required approval of such sale or of
      a
      purchase of such sale by any governmental regulatory authority or official.
      Grantor further agrees that such compliance shall not result in any such sale
      being deemed not to have been made in a commercially reasonable manner, nor
      shall Trustee be liable or accountable to Grantor for any discount allowed
      by
      reason of the fact that any Collateral is sold in compliance with any such
      limitation or restriction.

     

    (c) If
      any
      Event of Default shall occur and be continuing or shall exist, Trustee shall
      have the right, in addition to all other rights and remedies available to it
      hereunder or otherwise, without notice to Grantor, to set-off against and to
      appropriate and apply to the unpaid balance of the Notes and all other Secured
      Obligations, any obligations owing to Grantor by Trustee and any funds held
      in
      any manner for the account of Grantor by Trustee, and Trustee is hereby granted
      a security interest in and lien on all such obligations for such purpose. Such
      set-off rights shall exist whether or not Trustee shall have made any demand
      under this Agreement, the Indenture or any other Secured Obligations and whether
      the Notes and such other obligations are matured or unmatured.

     

    20. Further
      Funding; Expansion Debt.
      Section
      4.09 of the Indenture provides that Borrower may incur certain additional debt
      (herein called Expansion Debt as also defined in the Indenture) for the purpose
      of acquiring or constructing certain additional assets (herein called Expansion
      Assets as also defined in the Indenture). In the event that such Expansion
      Debt
      is incurred in accordance with the limitations of Section 4.09 of the Indenture
      but not issued in a manner that makes it part of the Indenture, as amended
      or
      modified, or issued under the Indenture but otherwise incurred with a separate
      lender, then Trustee agrees to release the security interest in the Secondary
      Equipment and Secondary Inventory not comprising the Rigs and, if required
      by
      the subsequent lender, the Stock Rights but only to the extent related to the
      Secondary Equipment and Secondary Inventory being released. 

     

    21. Application
      of Proceeds.
      Any
      Collateral or Proceeds of the Collateral received or realized upon at any time
      by Trustee shall be applied in the manner set forth in the Note (or if not
      so
      set forth, in a manner acceptable to, and at the election of, the Trustee).
      If
      the Proceeds of the Collateral together with the proceeds of any other
      collateral granted to Trustee by Borrower to secure the Secured Obligations,
      and
      of any sales or other dispositions thereof, shall be insufficient to fully
      discharge and satisfy the Secured Obligations, Borrower shall be liable for
      the
      deficiency, and if a surplus results after lawful application of such proceeds,
      either the Borrower or any other Grantor, to the extent such party has an
      entitlement to any such surplus.

      22. Bank
        Accounts.
        After
        the date of this Agreement, at the request of Trustee, Grantor shall execute
        and
        deliver to Trustee a depository account agreement or blocked account agreement,
        in form and substance reasonably satisfactory to Trustee and Grantor and
        accompanied by an appropriate executed acknowledgment, with respect to each
        bank
        or other financial institution where Grantor maintains accounts so that Trustee
        shall have control over the bank account upon the occurrence and continuance
        of
        an Event of Default, thereafter the Bank Account shall be subject to the
        terms
        of such depository account agreement of blocked account agreement.

    

     

    23. Continuing
      Validity of Obligations.

     

    (a) The
      agreements and obligations of the Grantor hereunder are continuing agreements
      and obligations and are absolute and unconditional irrespective of the
      genuineness, validity or enforceability of the Notes or any other instrument
      or
      instruments now or hereafter evidencing the Secured Obligations or any part
      thereof or of this Agreement or any other agreement or agreements now or
      hereafter entered into by Trustee and Grantor pursuant to which the Secured
      Obligations or any part thereof is issued or of any other circumstance which
      might otherwise constitute a legal or equitable discharge of such agreements
      and
      obligations other than payment in full of the Secured Obligations.

     

    (b) Without
      limitation upon the foregoing, such agreements and obligations of Grantor shall
      continue in full force and effect as long as the Secured Obligations or any
      part
      thereof remains outstanding and unpaid and shall remain in full force and effect
      without regard to and shall not be released, discharged or in any way affected
      by (i) any renewal, refinancing or refunding of the Secured Obligations in
      whole
      or in part, (ii) any extension of the time of payment of the Notes or other
      instrument or instruments now or hereafter evidencing the Secured Obligations
      or
      any part thereof, (iii) any amendment to or modification of the terms of the
      Notes or other instrument or instruments now or hereafter evidencing the Secured
      Obligations or any part thereof or any other agreement or agreements now or
      hereafter entered into by Trustee and Grantor pursuant to which the Secured
      Obligations or any part thereof is issued or secured, or (iv) any substitution,
      exchange or release of, or failure to preserve, perfect or protect, or other
      dealing in respect of, the Collateral or any other property or any security
      for
      the payment of the Secured Obligations or any part thereof. 

     

    (c) To
      the
      extent that Grantor makes a payment or payments to Trustee or Trustee receives
      any payment or proceeds of the Collateral, which payment or proceeds or any
      part
      thereof are subsequently invalidated, declared to be fraudulent or preferential,
      set aside or
      required to be repaid to Grantor or a trustee, receiver or any other party
      under
      any bankruptcy law, state or federal law, common law or equitable cause of
      action, then, to the extent of such payment or proceeds, the Secured Obligations
      or portion thereof intended to be satisfied and this Agreement shall be revived
      and continue in full force and effect, as if such payment or proceeds had not
      been received by such party.

      24. Defeasance.
        Upon
        payment in full of the Secured Obligations, this Agreement shall terminate
        and
        be of no further force and effect (except for the provisions of Sections
        25
        hereof which shall survive), and in such event Trustee shall, at Grantor’s
        expense and without recourse, representation or warranty, redeliver and reassign
        to Grantor the Collateral and take all action necessary to terminate Trustee’s
        security interest in the Collateral. This Agreement shall be binding upon
        and
        inure to the benefit of the parties hereto and their respective successors
        and
        assigns.

       

      25. Indemnification
        and Expenses.
        Grantor
        shall indemnify and hold harmless Trustee from and against any and all claims
        and losses arising out of or attributable to this Agreement, the Notes and
        all
        other related agreements, and the granting to Trustee of a security interest
        and
        lien in the Collateral hereunder, except claims and losses arising from
        Trustee’s breach hereof or Trustee’s gross negligence or willful misconduct.
        Grantor shall, jointly and severally, pay Trustee on demand the amount of
        any
        out-of-pocket expenses (including, without limitation, reasonable attorneys’
fees and other legal expenses) incurred by Trustee in connection with the
        enforcement of this Agreement, the Indenture and the Notes and as otherwise
        provided in this Agreement with interest accruing thereon at the Default
        Interest Rate.

    

     

    26. Saving
      Clause.
      Notwithstanding any other provision contained in this Agreement or the Notes,
      the aggregate interest rate per annum charged with respect to the Notes
      (including all charges and fees deemed to be interest pursuant to applicable
      law) shall not exceed the maximum rate per annum permitted by applicable law.
      In
      the event that the aggregate interest rate per annum payable with respect to
      the
      Notes (including all charges and fees deemed to be interest under applicable
      laws) exceeds the maximum legal rate, Borrower shall only pay Trustee interest
      at the maximum permitted rate, and Borrower shall continue to make such interest
      payments at the maximum permitted rate until all such interest payments and
      other charges and fees payable hereunder (in the absence of such legal
      limitations) have been paid in full.

     

    27. Modifications,
      Amendments or Waivers.
      The
      provisions of this Agreement may be modified, amended or waived, but only by
      a
      written instrument signed by Grantor and the Trustee.

     

    28. No
      Implied Waivers; Cumulative Remedies; Writing Required.
      No
      delay or failure of Trustee in exercising any right, power or remedy under
      this
      Agreement or the Indenture shall affect or operate as a waiver thereof, nor
      shall any single or partial exercise thereof or any abandonment or
      discontinuance of steps to enforce such a right, power or remedy preclude any
      further exercise thereof or of any other right, power or remedy. The rights
      and
      remedies of Trustee under this Agreement and the Indenture are cumulative and
      not exclusive of any rights or remedies which it would otherwise have,
      including, without limitation, any rights and remedies under any other
      agreement. Any waiver, permit, consent or approval of any kind or character
      on
      the part of Trustee of any breach or default or any such waiver of any provision
      or condition of this Agreement and the Indenture must be in writing and shall
      be
      effective only to the extent in such writing specifically set
      forth.

        of
        Texas or any other jurisdiction) that would cause the application of the

      be deemed to have exercised reasonable care in the custody and preservation
      of
      the Collateral in its possession if the Collateral is accorded treatment
      substantially equal to that which Trustee accords its own property.

      14. Records.
        With
        respect to Collateral in which it has rights or interests, Grantor shall
        at all
        times maintain accurate and complete records with respect to each item of
        Collateral constituting fixed assets, shall keep aggregate records regarding
        Inventory or Receivables, and shall otherwise keep books and records in
        accordance with the terms of the Indenture.

       

      15. Taxes
        and Charges.
        Grantor
        shall pay and discharge all taxes, levies and other impositions levied on
        any
        Collateral in which Grantor has rights or interests, in accordance with the
        terms of the Indenture, unless such failure to pay would not have a material
        adverse effect on the market value of the Collateral or if Grantor contest
        such
        tax, levy or imposition. If Grantor shall fail to do so, Trustee may (but
        shall
        not be obligated to) pay such taxes, levies or impositions for the account
        of
        Grantor (without waiving or releasing any obligation or default by Grantor
        hereunder), and the amount thereof shall be added to the Secured Obligations
        and
        shall be payable upon demand with interest accruing at the Default Interest
        Rate.

    

     

    16. Preservation
      and Protection of Security Interest.
      Except
      as otherwise provided herein, Grantor shall use its best efforts to diligently
      preserve and protect Trustee’s security interest in the Collateral in which
      Grantor has rights or interests and Borrower shall, at its expense, cause such
      security interest in such Collateral, other than the, vehicles and bank accounts
      (until required herein) owned by the Borrower to be perfected and continue
      perfected so long as the Secured Obligations or any portion thereof are
      outstanding
      and
      unpaid (including, without limitation, by means of the delivery of all
      instruments, documents of title and securities to Trustee with endorsements
      and
      documents of transfer satisfactory to Trustee), and for such purposes, Grantor
      shall from time to time at Trustee’s request and at its expense file or record,
      or cause to be filed or recorded, such instruments, documents and notices
      (including, without limitation, financing statements and continuation
      statements) as Trustee may deem necessary or advisable from time to time to
      perfect and continue perfected such security interests during the period, in
      accordance with the foregoing provision, that each Grantor has the obligation
      to
      cause such security interest to be perfected. Grantor shall do all such other
      acts and things and shall execute and deliver all such other instruments and
      documents (including, without limitation, further security agreements, pledge
      agreements, pledges, endorsements, assignments and notices) as Trustee may
      deem
      necessary or advisable from time to time to perfect and preserve the priority
      of
      Trustee’s security interest in the Collateral, as a perfected security interest
      in the Collateral (except as otherwise provided herein), prior to the rights
      of
      any other secured party or lien creditor, except with respect to Permitted
      Liens, which are accorded priority or as contemplated in the Intercreditor
      Agreement. Trustee, and its officers, employees and authorized agents, or any
      of
      them, are hereby irrevocably appointed the attorneys-in-fact of Grantor to
      do,
      at Grantor’s expense, all acts and things which Trustee may deem necessary or
      advisable to preserve, perfect and continue perfected Trustee’s security
      interest in the Collateral (including, without limitation, the signing of
      financing, continuation or other similar statements and notices on behalf of
      Grantor), which appointment is irrevocable and coupled with an interest.

     

    17. Federal
      Claims.
      Grantor
      shall notify Trustee of any Collateral which constitutes a claim against the
      United States government or any instrumentality or agency thereof, the
      assignment of which claim is governed by federal law. Upon the request of
      Trustee, Grantor shall at its expense take all actions required to comply,
      to
      Trustee’s satisfaction, with the Assignment of Claims
      Act of 1940, as amended, or any similar applicable law, with respect to any
      such
      Collateral having a value in excess of $10,000.

      18. Intercreditor
        Agreement.
        The
        Trustee hereby acknowledges and agrees that the exercise of remedies pursuant
        to
        paragraph 19 hereof and all other provisions of this Agreement are, and shall
        at
        all times be, subject to the limitations on the Trustee’s remedies set forth in
        the Intercreditor Agreement.

    

     

    19. Remedies
      on Default.
      Subject
      to the terms and conditions set forth in the Intercreditor
      Agreement:

     

    (a) If
      any
      Event of Default shall occur and be continuing or shall exist, Trustee may
      (i)
      to the full extent permitted by law, take possession and control of all or
      any
      part of the Collateral and Proceeds thereof and the books and records pertaining
      thereto, with or without judicial process, and (ii) after ten days prior written
      notice, proceed to exercise one or more of the rights and remedies accorded
      to a
      secured party by the UCC and otherwise by law or by the terms of the Indenture
      or this Agreement. Trustee’s rights and remedies shall include, without
      limitation, the power to (i) sell, lease, assign or otherwise dispose of and
      deliver all or any portion of the Collateral at public or private sale or sales
      at such place and time and on such terms as Trustee may see fit (subject to
      the
      requirements, including commercial reasonableness, of applicable law), (ii)
      endorse in the name of Grantor any Instrument representing Collateral, (iii)
      prosecute claims and legal actions regarding Accounts, other Receivables and
      General Intangibles, (iv) perform any agreement or contract which constitutes
      Collateral and (v) sell, assign, license, sublicense or otherwise dispose of,
      all right, title and interest in and to any General Intangibles included in
      the
      Collateral (including, without limitation, assignments, recordings,
      registrations and applications therefor in the United States Patent and
      Trademark Office, the United States Copyright Office or any similar domestic
      or
      foreign office or agency) and for the purpose of recording, registering and
      filing of, or accomplishing any other formality with respect to the foregoing,
      execute and deliver any and all agreements, documents, instruments of assignment
      or other papers necessary or advisable to effect such purpose. Without
      precluding any other methods of sale, the sale of Collateral shall be deemed
      to
      have been made in a commercially reasonable manner if conducted in conformity
      with reasonable commercial practices of secured lenders disposing of similar
      property, but in any event, Trustee may sell the Collateral on such terms as
      Trustee may choose without assuming any credit risk and without any obligation
      to advertise or give notice of any kind not expressly required under this
      Agreement or by the UCC or otherwise. All of the rights and remedies of Trustee
      under this Agreement shall be cumulative and not exclusive of other rights
      and
      remedies which it otherwise would have, whether under the Indenture, the UCC
      or
      otherwise. After the occurrence of an Event of Default, promptly upon the
      request of Trustee, Grantor shall assemble so much of the Collateral (including,
      without limitation, all books and records relating thereto) in its possession
      as
      is capable of physical delivery and make the same available to Trustee at such
      locations designated by Trustee reasonably convenient to both parties and shall
      permit Trustee, or Trustee’s representatives and agents, to enter any premises
      where all or any part of the Collateral, or the books and records relating
      thereto, or both, are located, to take possession of all or any part of the
      Collateral and to remove all or any part of the Collateral. The right of Trustee
      to have the Collateral assembled and made available to it is of the essence
      of
      this Agreement, and Trustee may, at its election, enforce such right by a bill
      in equity for injunctive relief for specific performance.
      Trustee shall not be under any obligation to marshal any assets in favor of
      Grantor or any other Person or against or in payment of all or any of the
      Secured Obligations.

    (b) Grantor
      agrees that in any sale of any of the Collateral, Trustee is authorized to
      comply with any limitation or restriction in connection with such sale which
      it
      is advised by its counsel is appropriate (i) to avoid violation of
      applicable law, or (ii) to obtain any required approval of such sale or of
      a
      purchase of such sale by any governmental regulatory authority or official.
      Grantor further agrees that such compliance shall not result in any such sale
      being deemed not to have been made in a commercially reasonable manner, nor
      shall Trustee be liable or accountable to Grantor for any discount allowed
      by
      reason of the fact that any Collateral is sold in compliance with any such
      limitation or restriction.

     

    (c) If
      any
      Event of Default shall occur and be continuing or shall exist, Trustee shall
      have the right, in addition to all other rights and remedies available to it
      hereunder or otherwise, without notice to Grantor, to set-off against and to
      appropriate and apply to the unpaid balance of the Notes and all other Secured
      Obligations, any obligations owing to Grantor by Trustee and any funds held
      in
      any manner for the account of Grantor by Trustee, and Trustee is hereby granted
      a security interest in and lien on all such obligations for such purpose. Such
      set-off rights shall exist whether or not Trustee shall have made any demand
      under this Agreement, the Indenture or any other Secured Obligations and whether
      the Notes and such other obligations are matured or unmatured.

     

    20. Further
      Funding; Expansion Debt.
      Section
      4.09 of the Indenture provides that Borrower may incur certain additional debt
      (herein called Expansion Debt as also defined in the Indenture) for the purpose
      of acquiring or constructing certain additional assets (herein called Expansion
      Assets as also defined in the Indenture). In the event that such Expansion
      Debt
      is incurred in accordance with the limitations of Section 4.09 of the Indenture
      but not issued in a manner that makes it part of the Indenture, as amended
      or
      modified, or issued under the Indenture but otherwise incurred with a separate
      lender, then Trustee agrees to release the security interest in the Secondary
      Equipment and Secondary Inventory not comprising the Rigs and, if required
      by
      the subsequent lender, the Stock Rights but only to the extent related to the
      Secondary Equipment and Secondary Inventory being released. 

     

    21. Application
      of Proceeds.
      Any
      Collateral or Proceeds of the Collateral received or realized upon at any time
      by Trustee shall be applied in the manner set forth in the Note (or if not
      so
      set forth, in a manner acceptable to, and at the election of, the Trustee).
      If
      the Proceeds of the Collateral together with the proceeds of any other
      collateral granted to Trustee by Borrower to secure the Secured Obligations,
      and
      of any sales or other dispositions thereof, shall be insufficient to fully
      discharge and satisfy the Secured Obligations, Borrower shall be liable for
      the
      deficiency, and if a surplus results after lawful application of such proceeds,
      either the Borrower or any other Grantor, to the extent such party has an
      entitlement to any such surplus.

     

    22. Bank
      Accounts.
      After
      the date of this Agreement, at the request of Trustee, Grantor shall execute
      and
      deliver to Trustee a depository account agreement or blocked account agreement,
      in form and substance reasonably satisfactory to Trustee and Grantor and
      accompanied by an appropriate executed acknowledgment, with respect to each
      bank
      or other financial institution where Grantor maintains accounts so that Trustee
      shall have control over the bank account upon the occurrence and continuance
      of
      an Event of Default, thereafter the Bank Account shall be subject to the terms
      of such depository account agreement of blocked account agreement.

      23. Continuing
        Validity of Obligations.

       

      (a) The
        agreements and obligations of the Grantor hereunder are continuing agreements
        and obligations and are absolute and unconditional irrespective of the
        genuineness, validity or enforceability of the Notes or any other instrument
        or
        instruments now or hereafter evidencing the Secured Obligations or any part
        thereof or of this Agreement or any other agreement or agreements now or
        hereafter entered into by Trustee and Grantor pursuant to which the Secured
        Obligations or any part thereof is issued or of any other circumstance which
        might otherwise constitute a legal or equitable discharge of such agreements
        and
        obligations other than payment in full of the Secured
        Obligations.

    

     

    (b) Without
      limitation upon the foregoing, such agreements and obligations of Grantor shall
      continue in full force and effect as long as the Secured Obligations or any
      part
      thereof remains outstanding and unpaid and shall remain in full force and effect
      without regard to and shall not be released, discharged or in any way affected
      by (i) any renewal, refinancing or refunding of the Secured Obligations in
      whole
      or in part, (ii) any extension of the time of payment of the Notes or other
      instrument or instruments now or hereafter evidencing the Secured Obligations
      or
      any part thereof, (iii) any amendment to or modification of the terms of the
      Notes or other instrument or instruments now or hereafter evidencing the Secured
      Obligations or any part thereof or any other agreement or agreements now or
      hereafter entered into by Trustee and Grantor pursuant to which the Secured
      Obligations or any part thereof is issued or secured, or (iv) any substitution,
      exchange or release of, or failure to preserve, perfect or protect, or other
      dealing in respect of, the Collateral or any other property or any security
      for
      the payment of the Secured Obligations or any part thereof. 

     

    (c) To
      the
      extent that Grantor makes a payment or payments to Trustee or Trustee receives
      any payment or proceeds of the Collateral, which payment or proceeds or any
      part
      thereof are subsequently invalidated, declared to be fraudulent or preferential,
      set aside or
      required to be repaid to Grantor or a trustee, receiver or any other party
      under
      any bankruptcy law, state or federal law, common law or equitable cause of
      action, then, to the extent of such payment or proceeds, the Secured Obligations
      or portion thereof intended to be satisfied and this Agreement shall be revived
      and continue in full force and effect, as if such payment or proceeds had not
      been received by such party.

     

    24. Defeasance.
      Upon
      payment in full of the Secured Obligations, this Agreement shall terminate
      and
      be of no further force and effect (except for the provisions of Sections 25
      hereof which shall survive), and in such event Trustee shall, at Grantor’s
      expense and without recourse, representation or warranty, redeliver and reassign
      to Grantor the Collateral and take all action necessary to terminate Trustee’s
      security interest in the Collateral. This Agreement shall be binding upon and
      inure to the benefit of the parties hereto and their respective successors
      and
      assigns.

      25. Indemnification
        and Expenses.
        Grantor
        shall indemnify and hold harmless Trustee from and against any and all claims
        and losses arising out of or attributable to this Agreement, the Notes and
        all
        other related agreements, and the granting to Trustee of a security interest
        and
        lien in the Collateral hereunder, except claims and losses arising from
        Trustee’s breach hereof or Trustee’s gross negligence or willful misconduct.
        Grantor shall, jointly and severally, pay Trustee on demand the amount of
        any
        out-of-pocket expenses (including, without limitation, reasonable attorneys’
fees and other legal expenses) incurred by Trustee in connection with the
        enforcement of this Agreement, the Indenture and the Notes and as otherwise
        provided in this Agreement with interest accruing thereon at the Default
        Interest Rate.

    

     

    26. Saving
      Clause.
      Notwithstanding any other provision contained in this Agreement or the Notes,
      the aggregate interest rate per annum charged with respect to the Notes
      (including all charges and fees deemed to be interest pursuant to applicable
      law) shall not exceed the maximum rate per annum permitted by applicable law.
      In
      the event that the aggregate interest rate per annum payable with respect to
      the
      Notes (including all charges and fees deemed to be interest under applicable
      laws) exceeds the maximum legal rate, Borrower shall only pay Trustee interest
      at the maximum permitted rate, and Borrower shall continue to make such interest
      payments at the maximum permitted rate until all such interest payments and
      other charges and fees payable hereunder (in the absence of such legal
      limitations) have been paid in full.

     

    27. Modifications,
      Amendments or Waivers.
      The
      provisions of this Agreement may be modified, amended or waived, but only by
      a
      written instrument signed by Grantor and the Trustee.

     

    28. No
      Implied Waivers; Cumulative Remedies; Writing Required.
      No
      delay or failure of Trustee in exercising any right, power or remedy under
      this
      Agreement or the Indenture shall affect or operate as a waiver thereof, nor
      shall any single or partial exercise thereof or any abandonment or
      discontinuance of steps to enforce such a right, power or remedy preclude any
      further exercise thereof or of any other right, power or remedy. The rights
      and
      remedies of Trustee under this Agreement and the Indenture are cumulative and
      not exclusive of any rights or remedies which it would otherwise have,
      including, without limitation, any rights and remedies under any other
      agreement. Any waiver, permit, consent or approval of any kind or character
      on
      the part of Trustee of any breach or default or any such waiver of any provision
      or condition of this Agreement and the Indenture must be in writing and shall
      be
      effective only to the extent in such writing specifically set
      forth.

        set
        forth in Section 29 hereof, and service so made shall be deemed to be completed
        on the seventh Business Day after the same shall have been deposited in the

        mails, postage prepaid. In addition, Grantor hereby waives, to the extent
        permitted by law, trial by jury, any objections based on
forum non conveniens and any objections to venue
        of any action arising out of, connected with, related to or incidental to
        the
        transactions contemplated by or the relationships established in connection
        with

    (c) Exclusive
      Jurisdiction.

      related to or incidental to the transactions contemplated by or the relationship
      established between them in connection with this Agreement and whether arising
      in contract, tort, equity or otherwise, shall be resolved only by state or
      federal courts located in the State of Texas, Harris County, and Grantor hereby
      consents and submits to the jurisdiction of any state or federal court located

      any
      appeals from those courts may be required to be heard by a court located outside
      the State of Texas, Harris County. Grantor waives in all disputes any objections
      that they may have to the location of the court considering the dispute. Nothing
      in this Section 31 shall affect the right of Trustee to serve legal process
      in
      any other manner permitted by law or affect the right of Trustee to bring any
      action or proceeding against Grantor or its property in the courts of any other
      jurisdiction.

      in
      any jurisdiction, such provision shall be ineffective only to the extent of
      such
      prohibition or invalidity, without invalidating any other provision of this
      Agreement.
