In the ordinary course of its business, the officers of Customer consider the effect of Environmental Laws on the business of Customer or any Business Guarantor, in the course of which they identify and evaluate potential risks and liabilities accruing to Customer due to Environmental Laws. On the basis of this consideration, Customer has concluded that Environmental Laws cannot reasonably be expected to have a material adverse

effect on the business, property, prospects, condition (financial or otherwise) or results of operations of Customer or any Business Guarantor. Neither Customer nor any Business Guarantor has received any notice to the effect that its operations are not in material compliance with any of the requirements of applicable Environmental Laws or are the subject of any federal or state investigation evaluating whether any remedial action is needed to respond to a release of any toxic or hazardous waste or substance into the environment, which non-compliance or remedial action could reasonably be expected to have a material adverse effect on the business, property, prospects, condition (financial or otherwise) or results of operations of Customer or any Business Guarantor. "Environmental Laws" shall mean any Federal, foreign, state or local law, rule or regulation pertaining to the protection of the environment, including, but not limited to, the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 ("CERCLA") (42 U.S.C. section 9601 et seq.), the Hazardous Material Transportation Act (49 U.S.C. section 1801 et seq.), the Federal Water Pollution Control Act (33 U.S.C. section 1251 et seq.), the Resource Conservation and Recovery Act (42 U.S.C. section 6901 et seq.), the Clean Air Act (42 U.S.C. section 7401 et seq.), the Toxic Substances Control Act (15 U.S.C. section 2601 et seq.), the Federal Insecticide, Fungicide, and Rodenticide Act (7 U.S.C. section 1361 et seq.), and the Occupational Safety and Health Act (19 U.S.C. section 651 et seq.), as these laws have been amended or supplemented, and any analogous foreign, Federal, state or local statutes, and the regulations promulgated pursuant thereto.

(n) Investment Company Act. Neither Customer nor any Business Guarantor is an "investment company" or a company "controlled" by an "investment company", within the meaning of the Investment Company Act of 1940, as amended.

(o) Public Utility Holding Company Act. Neither Customer nor any Business Guarantor is a "holding company" or a "subsidiary company" of a "holding company", or an "affiliate" of a "holding company" or of a "subsidiary company" of a "holding company", within the meaning of the Public Utility Holding Company Act of 1935, as amended.

Each of the foregoing representations and warranties: (i) has been and will be relied upon as an inducement to MLC to make the Loan, and (ii) is continuing and shall be deemed remade by Customer on the Closing Date.

(c) Performance of Obligations. Customer shall perform all of its obligations owing on account of or with respect to the Collateral; it being understood that nothing herein, and no action or inaction by MLC, under this Loan Agreement or otherwise, shall be deemed an assumption by MLC of any of Customer's said obligations.

(g) Location. On the Closing Date, Customer shall deliver to MLC a certificate signed by an authorized officer of Customer describing the physical location of each rig that comprises the Collateral. In no event shall Customer cause or permit any material tangible Collateral to be removed from the United States without the express prior written consent of MLC.

(h) Insurance.

Coverage. Without limiting any of the other obligations or liabilities of Customer under the Loan Documents, Customer shall, during the term of this Loan Agreement, carry and maintain, with respect to Collateral listed hereunder, at its own expense, at least the minimum insurance coverage as stated below, with insurers having a minimum A.M.

Customer shall also carry and maintain any other insurance that MLC may reasonably require from time to time.

(i) All risk or special form property insurance, insuring the Collateral against physical loss or damage from perils including but not limited to fire and extended coverage, windstorm, collapse, flood, and earth movement.

(iv) Other insurance in such amounts as may from time to time be reasonably required by MLC.

Endorsements. Customer shall cause all insurance policies carried and maintained in accordance with this Loan Agreement to endorse MLC, its successors and assigns as indicated below.

(i) As the sole loss payee as its interest may appear with respect to the Collateral under the all risk/special form. Any obligation imposed upon Customer, including but not limited to the obligation to pay premiums and/or coverage deductibles, shall be the sole obligation of Customer and not an obligation of MLC.

(ii) Inasmuch as such policies are written to cover more than one insured, all terms, conditions, insuring agreements and endorsements, with the exception of the limits of liability, shall operate in the same manner as if there were a separate policy covering each insured. This provision applies only to Section 3.4(h)(ii) and Section 3.4(h)(iii).

(iii) The insurers providing the coverage required hereunder shall waive all rights of subrogation against MLC, any right of setoff or counterclaim and any other right to deduction, whether by attachment or otherwise.

(iv) Such insurance shall be primary without right of contribution of any other insurance carried by or on behalf of MLC with respect to its interests as such in the Collateral.

(v) If such insurance is canceled for any reason whatsoever, including nonpayment of premium, or any material changes are made in the coverage which affect the interests of MLC, such cancellation or change shall not be effective as to MLC until 30 days, except for non-payment of premium which shall not be effective as to MLC until 10 days, after receipt by MLC of written notice sent by registered mail from such insurer.

(vi) Upon the occurrence of a Default hereunder, Customer irrevocably, appoints MLC as Customer's true and lawful attorney (and agent-in fact) for the purpose of making, settling and adjusting claims under such policies, endorsing the name of Customer on any check, draft, instrument or other item of payment for the proceeds of such policies and for making all determinations and decisions with respect to such policies.

(vii) MLC shall be named as an additional insured with respect to the Commercial General Liability and Excess or Umbrella Liability. Any obligation imposed upon Customer, including but not limited to the obligation to pay premiums and/or coverage deductibles, shall be the sole obligation of Customer and not an obligation of MLC.

Certifications. On the Closing Date with respect to the Collateral hereunder as of such date, and at each policy renewal, but not less than annually with respect to all Collateral, Customer shall provide to MLC an ▇▇▇▇▇ 27—Evidence of Property Insurance and loss payable endorsements for Property, and an ▇▇▇▇▇ 25 Certificate of Liability Insurance for General Liability, Umbrella or Excess Liability policies. All certificates shall identify the insurance carriers, the type of insurance, the limits, deductibles, and terms thereof and shall specifically list the special provisions delineated for such insurance required by this Section. Customer shall furnish to MLC a certificate signed by a duly authorized representative of the insurer, showing the insurance then maintained by or on behalf of Customer pursuant to this Section and stating that such insurance complies in all material aspects with the terms hereof, together with evidence of payment of premiums.

Forced Placement. In the event that at any time the insurance required by this Section shall be reduced or cease to be maintained, then (without limiting the rights of MLC hereunder in respect of the Default which arises as a result of such failure) MLC may at its option, maintain the insurance required hereby in such event. Customer shall reimburse MLC upon demand for the cost thereof with interest thereon at a rate per annum equal to the Default Rate, but in no event shall the rate of interest exceed the maximum rate permitted by law.

(i) Use. Customer agrees that the tangible Collateral will be used by Customer solely in the conduct of its business and in a manner complying in all material respects with all applicable laws and any applicable insurance policies. All tangible Collateral shall at all times remain personal property of Customer regardless of the degree of its annexation to any real property and shall not by reason of any installation in, or affixation to, real or personal property become a part thereof. Customer shall obtain and deliver to MLC (to be recorded at Customer's expense) from any Person having an interest in the property where the tangible Collateral is to be located, waivers of any lien, encumbrance or interest which such Person might have or hereafter obtain or claim with respect to the tangible Collateral.

(j) Event of Loss. Customer shall at its expense promptly repair all repairable damage to any tangible Collateral. In the event that there is an Event of Loss and the affected Collateral had a value prior to such Event of Loss of $500,000 or more, then, on or before the first to occur of (i) 90 days after the occurrence of such Event of Loss, or (ii) 10 Business Days after the date on which either Customer or MLC shall receive any proceeds of insurance on account of such Event of Loss, or any underwriter of insurance on such Collateral shall advise either Customer or MLC that it disclaims liability in respect of such Event of Loss, Customer shall, at Customer's option, either replace the Collateral subject to such Event of Loss with comparable Collateral free of all

liens other than Permitted Liens (in which event Customer shall be entitled to utilize the proceeds of insurance on account of such Event of Loss for such purpose, and may retain any excess proceeds of such insurance), or permanently prepay the Obligations by an amount equal to the actual cash value of such Collateral as determined by either the insurance company's payment (plus any applicable deductible) or, in absence of insurance company payment, as reasonably determined by MLC; it being further understood that any such permanent prepayment shall cause an immediate permanent reduction in the Loan in the amount of such prepayment and shall not reduce the amount of any future reductions in the Loan that may be required hereunder. Notwithstanding the foregoing, if at the time of occurrence of such Event of Loss or any time thereafter prior to replacement or line reduction, as aforesaid, an Event of Default shall have occurred and be continuing hereunder, then MLC may at its sole option, exercisable at any time while such Event of Default shall be continuing, require Customer to either replace such Collateral or prepay the Obligations, as aforesaid.

(k) Notice of Certain Events. Customer shall give MLC immediate notice of any attachment, lien, judicial process, encumbrance or claim affecting or involving the Collateral.

(l) INDEMNIFICATION. CUSTOMER SHALL INDEMNIFY, DEFEND AND SAVE MLC HARMLESS FROM AND AGAINST ANY AND ALL CLAIMS, LIABILITIES, LOSSES, COSTS AND EXPENSES (INCLUDING, WITHOUT LIMITATION, REASONABLE ATTORNEYS' FEES AND EXPENSES) OF ANY NATURE WHATSOEVER WHICH MAY BE ASSERTED AGAINST OR INCURRED BY MLC ARISING OUT OF OR IN ANY MANNER OCCASIONED BY (I) THE OWNERSHIP, COLLECTION, POSSESSION, USE OR OPERATION OF ANY COLLATERAL, OR (II) ANY FAILURE BY CUSTOMER TO PERFORM ANY OF ITS OBLIGATIONS HEREUNDER OR UNDER THE OTHER LOAN DOCUMENTS; EXCLUDING, HOWEVER, FROM SAID INDEMNITY ANY SUCH CLAIMS, LIABILITIES, ETC. ARISING DIRECTLY OUT OF THE WILLFUL WRONGFUL ACT OR ACTIVE GROSS NEGLIGENCE OF MLC AS DETERMINED IN A FINAL NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION. THIS INDEMNITY SHALL SURVIVE THE EXPIRATION OR TERMINATION OF THIS LOAN AGREEMENT AS TO ALL MATTERS ARISING OR ACCRUING PRIOR TO SUCH EXPIRATION OR TERMINATION.

The existence of such a material impairment shall be determined in a manner consistent with the intent of Section 1-208 of the UCC.

(l) Dissolution. The dissolution or the filing for dissolution of any Credit Party.

(i) Termination. MLC may without notice terminate its obligation to extend any credit to or for the benefit of Customer (it being understood, however, that upon the occurrence of

any Bankruptcy Event all such obligations shall automatically terminate without any action on the part of MLC).

(ii) Acceleration. MLC may declare the principal of and interest and any premium on the Note, and all other Obligations to be forthwith due and payable, whereupon all such amounts shall be immediately due and payable, without presentment, demand for payment, protest and notice of protest, notice of dishonor, notice of acceleration, notice of intent to accelerate or other notice or formality of any kind, all of which are hereby expressly waived; provided, however, that upon the occurrence of any Bankruptcy Event all such principal, interest, premium and other Obligations shall automatically become due and payable without any action on the part of MLC.

(iii) Exercise Other Rights. MLC may exercise any or all of the remedies of a secured party under applicable law and in equity, including, but not limited to, the UCC, and any or all of its other rights and remedies under the Loan Documents.

(iv) Possession. MLC may require Customer to make the Collateral and the records pertaining to the Collateral available to MLC at a place designated by MLC which is reasonably convenient to Customer, or may take possession of the Collateral and the records pertaining to the Collateral without the use of any judicial process and without any prior notice to Customer. MLC's sole duty with respect to the custody, safe-keeping, and physical preservation of any Collateral in its possession, under Section 9.207 of the UCC or otherwise, shall be to deal with such Collateral in the same manner as MLC deals with similar property for its own account.

(v) Sale. MLC may sell any or all of the Collateral at public or private sale upon such terms and conditions as MLC may reasonably deem proper, whether for cash, on credit, or for future delivery, in bulk or in lots. MLC may purchase any Collateral at any such sale free of Customer's right of redemption, if any, which Customer expressly waives to the extent not prohibited by applicable law. The net proceeds of any such public or private sale and all other amounts actually collected or received by MLC pursuant hereto, after deducting all costs and expenses incurred at any time in the collection of the Obligations and in the protection, collection and sale of the Collateral, will be applied to the payment of the Obligations, with any remaining proceeds paid to Customer or whoever else may be entitled thereto, and with Customer and each Guarantor remaining jointly and severally liable for any amount remaining unpaid after such application. MLC has no obligation to repair, refurbish or otherwise prepare the Collateral for sale, lease or other use or dispostiion as authorized herein. If MLC sells any Collateral upon credit, Customer will receive credit against the Obligations only for cash payments made by the purchaser to MLC. If the purchaser fails to pay the purchase price, then MLC may resell the Collateral.

(vi) Delivery of Cash, Checks, Etc. MLC may require Customer to forthwith upon receipt, transmit and deliver to MLC in the form received, all cash, checks, drafts and other instruments for the payment of money (properly endorsed, where required, so that such items may be collected by MLC) which may be received by Customer at any time in full or partial payment of any Collateral, and require that Customer not commingle any such items which may be so received by Customer with any other of its funds or property but instead hold them separate and apart and in trust for MLC until delivery is made to MLC.

(vii) Notification of Account Debtors. MLC may notify any account debtor that its Account or Chattel Paper has been assigned to MLC and direct such account debtor to make payment directly to MLC of all amounts due or becoming due with respect to such Account or Chattel Paper; and MLC may enforce payment and collect, by legal proceedings or otherwise, such Account or Chattel Paper.

(viii) Control of Collateral. MLC may otherwise take control in any lawful manner of any cash or non-cash items of payment or proceeds of Collateral and of any rejected, returned, stopped in transit or repossessed goods included in the Collateral and endorse Customer's name on any item of payment on or proceeds of the Collateral.

(b) Set-Off. MLC shall have the further right upon the occurrence and during the continuance of an Event of Default to set-off, appropriate and apply toward payment of any of the Obligations, in such order of application as MLC may from time to time and at any time elect, any cash, credit, deposits, accounts, financial assets, investment property, securities and any other property of Customer which is in transit to or in the possession, custody or control of MLC, MLPF&S or any agent, bailee, or affiliate of MLC or MLPF&S. Customer hereby collaterally assigns and grants to MLC a continuing security interest in all such property as Collateral and as additional security for the Obligations. Upon the occurrence and during the continuance of an Event of Default, MLC shall have all rights in such property available to collateral assignees and secured parties under all applicable laws, including, without limitation, the UCC.

(c) Power of Attorney. Effective upon the occurrence and during the continuance of an Event of Default, Customer hereby irrevocably appoints MLC as its attorney-in-fact, with full power of substitution, in its place and stead and in its name or in the name of MLC, to from time to time in MLC's sole discretion take any action and to execute any instrument which MLC may deem necessary or advisable to accomplish the purposes of this Loan Agreement and the other Loan Documents, including, but not limited to, to receive, endorse and collect all checks, drafts and other instruments for the payment of money made payable to Customer included in the Collateral. The powers of attorney granted to MLC in this Loan Agreement are coupled with an interest and are irrevocable until the Obligations have been indefeasibly paid in full and fully satisfied and all obligations of MLC under this Loan Agreement have been terminated.

(d) Remedies are Severable and Cumulative. All rights and remedies of MLC herein are severable and cumulative and in addition to all other rights and remedies available in the Note, the other Loan Documents, at law or in equity, and any one or more of such rights and remedies may be exercised simultaneously or successively.

(e) No Marshalling. MLC shall be under no duty or obligation to (i) preserve, protect or ▇▇▇▇▇▇▇▇ the Collateral, except to the extent that MLC has taken possession of the Collateral and as provided in Section 3.6(a)(iv) hereof; (ii) preserve or protect the rights of any Credit Party or any other Person claiming an interest in the Collateral; (iii) realize upon the Collateral in any particular order or manner, (iv) seek repayment of any Obligations from any particular source; (v) proceed or not proceed against any Credit Party pursuant to any guaranty or security agreement or against any Credit Party under the Loan Documents, with or without also realizing on the Collateral; (vi) permit any substitution or exchange of all or any part of the Collateral; or (vii) release any part of the Collateral from the Loan Agreement or any of the other Loan Documents, whether or not such substitution or release would leave MLC adequately secured.

(f) Notices. To the fullest extent permitted by applicable law, Customer hereby irrevocably waives and releases MLC of and from any and all liabilities and penalties for failure of MLC to comply with any statutory or other requirement imposed upon MLC relating to notices of sale, holding of sale or reporting of any sale, and Customer waives all rights of redemption or reinstatement from any such sale. Any notices required under applicable law shall be reasonably and properly given to Customer if given by any of the methods provided herein at least 5 Business Days prior to taking action. MLC shall have the right to postpone or adjourn any sale or other disposition of Collateral at any time without giving notice of any such postponed or adjourned date. In the event MLC seeks to take possession of any or all of the Collateral by court process, Customer further irrevocably waives to the fullest extent permitted by law any bonds and any surety or security relating thereto required by any statute, court rule or otherwise as an incident to such possession, and any demand for possession prior to the commencement of any suit or action.

Section 3.7 Miscellaneous.

(a) Non-Waiver. No failure or delay on the part of MLC in exercising any right, power or remedy pursuant to this Loan Agreement, the Note or any of the other Loan Documents shall operate as a waiver thereof, and no single or partial exercise of any such right, power or remedy shall preclude any other or further exercise thereof, or the exercise of any other right, power or remedy. Neither any waiver of any provision of this Loan Agreement, the Note or any of the other Loan Documents, nor any consent to any departure by Customer therefrom, shall be effective unless the same shall be in writing and signed by MLC. Any waiver of any provision of this Loan Agreement, the Note or any of the other Loan Documents and any consent to any departure by Customer from the terms of this Loan Agreement, the Note or any of the other Loan Documents shall be effective only in the specific instance and for the specific purpose for which given. Except as otherwise expressly provided herein, no notice to or demand on Customer shall in any case entitle Customer to any other or further notice or demand in similar or other circumstances.

(b) Disclosure. Customer hereby irrevocably authorizes MLC and each of its affiliates, to at any time (whether or not an Event of Default shall have occurred) obtain from and disclose to each other any and all financial and other information about Customer. Customer further irrevocably authorizes MLC to contact, investigate, inquire and obtain references and other information on Customer from credit reporting services and agencies, former or current creditors, and other persons and sources (including, without limitation, any Affiliate of MLC) and to provide to any references, credit reporting services and agencies, creditors and other persons and sources (including, without limitation, Affiliates of MLC) all financial, credit and other information obtained by MLC relating to the Customer.

Notices may be addressed to Customer as set forth at its address shown in the preamble hereto, or to any office to which billing or account statements are sent; to MLC at its address shown in the preamble hereto, or at such other address designated in writing by MLC. Any such communication shall be deemed to have been given upon, in the case of personal delivery the date of delivery, one Business Day after deposit with an overnight courier, two (2) Business Days after deposit in the United States by certified mail (return receipt required), or receipt of electronic transmission (which shall be presumed to be three hours after the time of transmission unless an error message is received by the sender), except that any notice of change of address shall not be effective until actually received.

(d) Fees, Expenses and Taxes. Customer shall upon demand pay or reimburse MLC for: (i) all UCC, real property or other filing, recording and search fees and expenses incurred by MLC in connection with the verification, perfection or preservation of MLC's rights hereunder or in any Collateral or any other collateral for the Obligations; (ii) any and all stamp, transfer, mortgage, intangible, document, filing, recording and other taxes and fees payable or determined to be payable in connection with the borrowings hereunder or the execution, delivery, filing and/or recording of the Loan Documents and any other instruments or documents provided for herein or delivered or to be delivered hereunder or in connection herewith; and (iii) all reasonable fees and out-of-pocket expenses (including reasonable attorneys' fees and legal expenses) incurred by MLC in connection with the preparation, execution, administration, collection, enforcement, protection, waiver or amendment of this Loan Agreement, or under any of the other Loan Documents and such other instruments or documents, and the rights and remedies of MLC thereunder and all

other matters in connection therewith. The obligations of Customer under this paragraph shall survive the expiration or termination of this Loan Agreement and the discharge of the other Obligations.

(e) Right to Perform Obligations. If Customer shall fail to do any act or thing which it has covenanted to do under this Loan Agreement or any of the Loan Documents, or any representation or warranty on the part of Customer contained in this Loan Agreement or any of the Loan Documents shall be breached, MLC may, in its sole discretion, after 5 Business Days written notice is sent to Customer (or such lesser notice, including no notice, as is reasonable under the circumstances), do the same or cause it to be done or remedy any such breach, and may expend its funds for such purpose. Any and all reasonable amounts so expended by MLC shall be repayable to MLC by Customer upon demand, with interest at the "Interest Rate" (as that item is defined in the Note) during the period from and including the date funds are so expended by MLC to the date of repayment, and all such amounts shall be additional Obligations. The payment or performance by MLC of any of Customer's obligations hereunder shall not relieve Customer of said obligations or of the consequences of having failed to pay or perform the same, and shall not waive or be deemed a cure of any Default.

(f) Late Charge. Any payment required to be made by Customer pursuant to this Loan Agreement or any of the Loan Documents not paid within ten (10) days of the applicable due date shall be subject to a late charge in an amount equal to the lesser of: (i) 5% of the overdue amount, or (ii) the maximum amount permitted by applicable law. Such late charge shall be payable on demand.

(h) Binding Effect. This Loan Agreement, the Note and the other Loan Documents shall be binding upon, and shall inure to the benefit of MLC, Customer and their respective successors and assigns.

MLC also reserves the right at any time to pool the Loan with one or more other loans originated by MLC or any other Person, and to securitize or offer interests in such pool on whatever terms and conditions MLC shall determine. Customer consents to MLC releasing financial and other information regarding Credit Parties, the Collateral and the Loan in connection with any such sale, pooling, securitization or other offering. Customer shall not assign any of its rights or delegate any of its obligations under this Loan Agreement, the Note or any of the other Loan Documents without the prior written consent of MLC. Unless otherwise expressly agreed to in a writing signed by MLC, no such consent shall in any event relieve Customer of any of its obligations under this Loan Agreement, the Note or any of the other Loan Documents.
