–

Facility #1 is available by way of:

	–		Prime-based loans in Canadian dollars

–

Notwithstanding the amount of Facility #1 (and except as otherwise provided in the Repayment section hereof), advances will be limited to the amount equal to the lesser of:

	–		the maximum principal amount of Facility #1; and

	–		an amount equal to 50% of the Tangible Asset Value of Tangible Assets then subject to the Security Documents.

–

Facility #1 is to be used for the acquisition of Tangible Assets. Each advance shall be supported by an officer’s certificate detailing the Tangible Asset being acquired, and shall not exceed 100% of the cost of the asset being acquired less GST and all appropriate taxes. The initial advance can be used to reimburse Borrower for the cost of Tangible Assets previously acquired by it, subject to the approval of Lender as to the assets, including their acquisition date.

2.		INTEREST RATES AND PREPAYMENT:

		Facility #1:

–

Pricing applicable to Facility #1 is as follows:

	–		Prime-based loans: Interest is payable in Canadian dollars at Prime plus the Applicable Facility #1 Margin per 365-day period

	–		Guaranteed Notes: Acceptance fee is payable in Canadian dollars at the Applicable Facility #1 Margin per 365-day period

The Applicable Facility #1 Margin shall be equal to the percentage rate per annum set out in the following table opposite the applicable ratio for the Borrower at the time of determination:

Ratio of Tangible Asset
Value to outstanding Borrowings	Prime-based loans	Guaranteed Notes
≤ 3.00:1	0%	1.50%
>2.50 but < 3.00:1	0.25%	1.75%
> 2.00:1 but < 2.50:1	0.50%	2.00%

	–		The effective date of any change to the Applicable Facility #1 Margin shall be the 1st day of the fiscal quarter immediately following the last day of the period during which the Borrower is required to deliver financial statements hereunder. If financial statements are not delivered as required hereunder, the Applicable Facility #1 Margin shall immediately be the highest rate applicable, until such time as such financial statements are delivered and the ratio determined. If the Applicable Facility #1 Margin changes during the term of any Guaranteed Note, the acceptance fee paid shall be adjusted to reflect the Applicable Facility #1 Margin for the remaining term, and the parties shall forthwith make whatever payments are necessary to reflect such adjustment.

	–		The Applicable Facility #1 Margin shall be subject to a 0.50% increase on and after the Term Date.

	–		Facility #1 may be prepaid in whole or in part at any time (subject to the notice periods provided hereunder) without penalty, except that Guaranteed Notes cannot be prepaid prior to their maturity.

	–		The “Term Date” is initially February 28, 2008, subject to extension as herein provided.

	–		Prior to the Term Date, Facility #1 may revolve in multiples as permitted hereunder, and Borrower may borrow, repay, reborrow and convert between types of Borrowings, up to the amount and subject to the notice periods provided herein.

	–		On the Term Date, any unutilized amount of Facility #1 will be cancelled, and the amount of Facility #1 will be reduced to the aggregate Borrowings outstanding on that date. On and after the Term Date, Facility #1 is non-revolving, and amounts repaid may not be re-borrowed, but Borrower can convert between types of Borrowings subject to the notice periods provided hereunder. All amounts outstanding under Facility #1 are due and payable in full on the date falling one (1) year after the Term Date.

	–		Borrower may request an extension of the Term Date by sending Lender a written request for extension in the form attached as Schedule “C” by no later than 90 days prior to the

Page 3

then current Term Date, and Lender may in its sole discretion agree to extend the Term Date for a further period of up to 364 days. Lender shall advise Borrower of its decision regarding the extension by no later than 30 days prior to the then current Term Date.

FEES:

	–		Non-refundable application fee of $45,000 is payable on acceptance of this offer. Lender is hereby authorized to debit Borrower’s current account for any unpaid portion of the fee.

	–		Any amount in excess of established credit facilities may be subject to a fee where Lender in its sole discretion permits excess Borrowings, if any.

–

Interest on Prime-based loans is calculated on the daily outstanding principal balance, and is payable on the last day of each month.



Midfield Supply ULC		May 17, 2007
Page 10

	–		If Guaranteed Notes are available hereunder, Borrower will issue non-interest bearing promissory notes to Lender in multiples of $100,000, subject to a minimum of $1,000,000, with a minimum term of 30 days and up to 90 day maturity dates. Borrower agrees to be bound by the power of attorney set out in Schedule “B” hereto. On the date of drawdown, Lender shall make an advance to Borrower in an amount equal to the proceeds which would have been realized from a hypothetical sale of those Guaranteed Notes at the Discount Rate, less the acceptance fees payable hereunder. Lender is authorized to hold or negotiate any such promissory notes. Guaranteed Notes shall remain in effect until the maturity of the term selected and notwithstanding anything to the contrary contained herein, may not be repaid prior to their maturity. On the maturity date thereof, Borrower shall pay Lender the face amount of each Guaranteed Note. If Lender does not receive written instructions from Borrower prior to maturity concerning the renewal of the Guaranteed Notes, then the face amount of the Guaranteed Notes shall be automatically deemed to be outstanding as a Prime-based loan under the relevant Facility until written instructions are received from Borrower.

	–		Borrower shall monitor its Borrowings (including the face amount and maturity date of each Guaranteed Note) to ensure that the Borrowings hereunder do not exceed the maximum amount available hereunder. Lender shall have no obligation to make any Borrowing available in excess of amounts available hereunder.

	–		Borrower shall provide notice to Lender prior to requesting an advance or making a repayment or conversion of Borrowings hereunder, as follows:

			For Borrowings:

	–		under Cdn. $5,000,000 – same day notice

	–		Cdn. $5,000,000 and over – one Business Day prior written notice

	–		Borrower may cancel the availability of any unused portion of a Facility on five Business Days’ notice. Any such cancellation is irrevocable.

	–		The annual rates of interest or fees to which the rates calculated in accordance with this agreement are equivalent, are the rates so calculated multiplied by the actual number of days in the calendar year in which such calculation is made and divided by 365.

	–		If any amount due hereunder is not paid when due, Borrower shall pay interest on such unpaid amount (including without limitation, interest on interest) if and to the fullest extent permitted by applicable law, at a rate per annum equal to Prime plus 5%.

	–		The branch of Lender (the “Branch of Account”) where Borrower maintains an account and through which the Borrowings will be made available is located at 219 — 2nd Street West, Brooks, Alberta T1R 1B5. Funds under the Credit Facilities will be advanced into and repaid from account no. 752-1090003-24 at the Branch of Account, or such other branch or account as Borrower and Lender may agree upon from time to time.

	–		Lender shall open and maintain at the Branch of Account accounts and records evidencing the Borrowings made available to Borrower by Lender under this agreement. Lender shall record the principal amount of each Borrowing and the payment of principal, interest and fees and all other amounts becoming due to Lender under this agreement. Lender’s accounts and records constitute, in the absence of manifest error,



Midfield Supply ULC		May 17, 2007
Page 11

			conclusive evidence of the indebtedness of Borrower to Lender pursuant to this agreement.

	–		Borrower authorizes and directs Lender to automatically debit, by mechanical, electronic or manual means, any bank account of Borrower for all amounts payable by Borrower to Lender pursuant to this agreement. Any amount due on a day other than a Business Day shall be deemed to be due on the Business Day next following such day, and interest shall accrue accordingly.

14.		EVENTS OF DEFAULT:

		If any of the events set forth below (an “Event of Default”) occurs and is continuing, Lender may at its option, by notice to Borrower, terminate any or all of the Facilities hereunder and demand immediate payment in full of all or any part of the amounts owed by Borrower thereunder:

	(a)		if Borrower defaults in paying when due all or any part of the principal amount due hereunder;

	(b)		if Borrower or any Guarantor defaults in paying when due all or any part of its indebtedness or other liability to Lender (other than as provided under section (a) above) and such default continues for 3 business days after notice from Lender;

	(c)		if Borrower or any Guarantor defaults in the observance or performance of any of its covenants or obligations hereunder or in any of the Security Documents (other than as provided under section (a) or (b) above), or in any other document under which Borrower or such Guarantor is obligated to Lender, and in any such cases, the default continues for 15 days after notice from Lender;

	(d)		if any charge or encumbrance on any Tangible Assets of Borrower or any Guarantor becomes enforceable and steps are taken to enforce it;

	(e)		if any charge or encumbrance on any property of Borrower or any Guarantor (other than the Tangible Assets) having a fair market value in excess of $5,000,000 becomes enforceable and steps are taken to enforce it;

	(f)		if Borrower or any Guarantor defaults in any obligation under the Syndicated Facility;

	(g)		if a Remedial Action Notice (as defined in the Intercreditor Agreement) is delivered under the Intercreditor Agreement;

	(h)		if an Activation Notice (as defined in the Blocked Account Agreement) is delivered under the Blocked Account Agreement;

	(i)		if Borrower or any Guarantor defaults in any obligation to any person (other than Lender or under the Syndicated Facility) which involves or may involve a sum exceeding $5,000,000, and the default has not been cured within 5 days of the date Borrower first knew or should have known of the default;

	(j)		if any other creditor of Borrower or any Guarantor takes collection steps against Borrower or such Guarantor or its assets;



Midfield Supply ULC		May 17, 2007
Page 12

	(k)		if final judgment or judgments should be entered against Borrower or any Guarantor for the payment of any amount of money exceeding $5,000,000, and the judgment or judgments are not discharged within 20 days after entry;

	(l)		if an order is made, an effective resolution passed, or a petition is filed for the winding up the affairs of Borrower or any Guarantor or if a receiver or liquidator of Borrower or any Guarantor or any part of its assets is appointed;

	(m)		if Borrower or any Guarantor becomes insolvent or makes a general assignment for the benefit of its creditors or an assignment in bankruptcy or files a proposal or notice of intention to file a proposal under the Bankruptcy and Insolvency Act or otherwise acknowledges its insolvency or if a bankruptcy petition is filed or receiving order is made against Borrower or any Guarantor and is not being disputed in good faith;

	(n)		if Borrower or any Guarantor ceases or threatens to cease to carry on its business or makes a bulk sale of its assets;

	(o)		if any of the licences, permits or approvals granted by any government or governmental authority or agency and material to the business of Borrower or any Guarantor is withdrawn, cancelled, suspended or adversely amended;

	(p)		if Red Man and Midfield Holdings cease to be shareholders of Borrower or there is any other change in the ownership or control of Borrower which is not acceptable to Lender, acting reasonably. A change in the ownership or control of Borrower will mean any person acquiring more than 50% of the outstanding shares of Borrower; or

	(q)		if any event or circumstance occurs which has or would reasonably be expected to have a Material Adverse Effect (as determined by Lender in its sole discretion).

		Failing such immediate payment, Lender may, without further notice, realize under the Security Documents to the extent Lender chooses.

15.		MISCELLANEOUS:

	(a)		All legal and other costs and expenses incurred by Lender in respect of the Facilities, the Security Documents and other related matters will be paid or reimbursed by Borrower on demand by Lender.
