The information in this prospectus is not complete and may be changed. We may not sell these securities until the registration statement filed with the Securities and Exchange Commission is effective. This prospectus is not an offer to sell these securities and it is not soliciting an offer to buy these securities in any state where the offer or sale is not permitted.

SUBJECT TO COMPLETION, DATED February 18, 2015

PRELIMINARY PROSPECTUS

US$400,000,000

PRECISION DRILLING CORPORATION

Offer to Exchange all outstanding US$400,000,000 5.250% Senior Notes due 2024 (the “Outstanding Notes”) for an equal amount of 5.250% Senior Notes due 2024, which have been registered under the Securities Act (the “Exchange Notes”).

The Exchange Offer

| • |  | We will exchange all Outstanding Notes that are validly tendered and not validly withdrawn for an equal principal amount of Exchange Notes that are freely tradable in the United States.

| • |  | You may withdraw tenders of Outstanding Notes at any time prior to the expiration date of the exchange offer.

| • |  | The exchange offer expires at 11:59 p.m., New York City time, on , 2015, unless extended. We do not currently intend to extend the expiration date.

| • |  | The exchange of Outstanding Notes for Exchange Notes in the exchange offer will not be a taxable event for U.S. federal income tax purposes.

| • |  | We will not receive any proceeds from the exchange offer.

The Exchange Notes

| • |  | The Exchange Notes are being offered in order to satisfy certain of our obligations under the registration rights agreement entered into in connection with the placement of the Outstanding Notes.

| • |  | The terms of the Exchange Notes to be issued in the exchange offer are substantially identical to the Outstanding Notes, except that the Exchange Notes will be freely tradable in the United States.

| • |  | Certain of Precision Drilling Corporation’s United States and Canadian subsidiaries jointly and severally, irrevocably and unconditionally guarantee, on a senior basis, the performance and full and punctual payment when due, whether at maturity, by acceleration or otherwise, of all obligations of Precision Drilling Corporation under the Outstanding Notes, the Exchange Notes and the indenture governing the notes.

Resales of Exchange Notes

| • |  | The Exchange Notes may be sold in the over-the-counter market, in negotiated transactions or through a combination of such methods. We do not plan to list the Exchange Notes on a national market.

All untendered Outstanding Notes will continue to be subject to the restrictions on transfer set forth in the Outstanding Notes and in the indenture governing the notes. In general, the Outstanding Notes may not be offered or sold, unless registered under the Securities Act, except pursuant to an exemption from, or in a transaction not subject to, the Securities Act, and applicable state securities laws. Other than in connection with the exchange offer, we do not currently anticipate that we will register the Outstanding Notes under the Securities Act.

You should consider carefully the risk factors beginning on page 13 of this prospectus before participating in the exchange offer.

This offering is made by a foreign issuer that is permitted, under a multijurisdictional disclosure system adopted by the United States, to prepare this prospectus in accordance with Canadian disclosure requirements. Prospective investors should be aware that such requirements are different from those of the United States. Financial statements included or incorporated herein have been prepared in accordance with International Financial Reporting Standards, as issued by the International Accounting Standards Board (“IFRS”), and thus may not be comparable to financial statements of United States companies.

Prospective investors should be aware that the acquisition of the securities described herein may have tax consequences both in the United States and in Canada. Such consequences for investors who are resident in, or citizens of, the United States may not be described fully herein.

Your ability to enforce civil liabilities under the United States federal securities laws may be affected adversely because we are incorporated in Canada, most of our officers and directors and some of the experts named in this prospectus are not residents of the United States, and many of our assets and all or a substantial portion of the assets of such persons are located outside of the United States.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of the Exchange Notes to be distributed in the exchange offer or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

Prospective investors should be aware that, during the period of the exchange offer, the registrant or its affiliates, directly or indirectly, may bid for or make purchases of Notes to be distributed or to be exchanged, or certain related debt securities, as permitted by applicable laws or regulations of Canada, or its provinces or territories.

Each broker-dealer that receives Exchanges Notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes. The letter of transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of the Exchange Notes received for the Outstanding Notes where such Outstanding Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities. Precision Drilling Corporation has agreed that, for a period of 180 days after the Expiration Date (as defined herein), it will make this prospectus available to any broker-dealer for use in connection with any such resale. See “Plan of Distribution.”

The date of this prospectus is , 2015.

This prospectus does not constitute an offer to sell, or a solicitation of an offer to buy, any of the Exchange Notes to any person in any jurisdiction where it is unlawful to make such an offer or solicitation. The information contained or incorporated by reference in this prospectus speaks only as of the date of this prospectus or the date of such incorporated document unless the information specifically indicates that another date applies. No dealer, salesperson or other person has been authorized to give any information or to make any representations other than those contained or incorporated by reference in this prospectus in connection with the offer contained herein and, if given or made, such information or representations must not be relied upon as having been authorized by Precision Drilling Corporation (“Precision”).

ENFORCEABILITY OF CIVIL LIABILITIES AGAINST FOREIGN PERSONS

Precision is a corporation amalgamated under the laws of the Province of Alberta and is governed by the applicable provincial and federal laws of Canada. A majority of our directors and officers and some of the experts named in this prospectus and the documents incorporated by reference herein reside principally in Canada. Because most of these persons are located outside the United States, it may not be possible for you to effect service of process within the United States on these persons. Furthermore, it may not be possible for you to enforce against us or them, in the United States, judgments obtained in U.S. courts, because a portion of our assets and a substantial portion of the assets of these persons are located outside the United States.

There is doubt as to the enforceability, in original actions in Canadian courts, of liabilities based on the United States federal securities laws or “blue sky” laws of any state within the U.S. and as to the enforceability in Canadian courts of judgments of U.S. courts obtained in actions based on the civil liability provisions of the United States federal securities laws or any such state securities or blue sky laws. Therefore, it may not be possible to enforce those judgments against us, our directors and officers or some of the experts named in this prospectus or the documents incorporated by reference herein.

PRESENTATION OF FINANCIAL INFORMATION

In this prospectus references to “C$” and “Canadian dollars” are to Canadian dollars and references to “US$” and “U.S. dollars” are to U.S. dollars. See “Currency Translation” below.

Rounding adjustments have been made in calculating some of the financial information included in this prospectus or incorporated by reference herein. As a result, numerical figures shown as totals in some tables may not be exact arithmetic aggregations of the figures that precede them.

The financial statements and financial information included and incorporated by reference in this prospectus have been prepared in accordance with IFRS. IFRS differs in some material respects from U.S. generally accepted accounting principles (“U.S. GAAP”), and so these financial statements and financial information may not be comparable to the financial statements and financial information of U.S. companies.

The audited financial statements of Precision as of December 31, 2013 and December 31, 2012 and for the years ended December 31, 2013, 2012 and 2011 and the unaudited financial statements of Precision as of September 30, 2014 and for the three and nine months ended September 30, 2014 and 2013 incorporated by reference in this prospectus have been prepared in accordance with IFRS and have not been reconciled to U.S. GAAP.

The financial results of Precision’s subsidiaries that have guaranteed the obligations of Precision under the Outstanding Notes, the Exchange Notes and the indenture governing the notes are included in the consolidated financial results of Precision.

The Exchange Offer

On June 3, 2014, Precision completed the private offering of US$400,000,000 aggregate principal amount of our 5.250% Senior Notes due 2024 (the “private offering”), which we refer in this prospectus as the “Outstanding Notes.” The term “Exchange Notes” refers to the 5.250% Senior Notes due 2024 as registered under the Securities Act of 1933, as amended (the “Securities Act”). References to the “notes” in this prospectus are references to both the Outstanding Notes and the Exchange Notes. This prospectus is part of a registration statement covering the exchange of the Outstanding Notes for the Exchange Notes.

Precision and the guarantors of the Outstanding Notes (the “guarantors”) entered into a registration rights agreement with the initial purchasers in the private offering in which Precision and the guarantors agreed to file a registration statement with the Securities and Exchange Commission (the “SEC”) with respect to a registered offer to exchange the Outstanding Notes for the Exchange Notes, use commercially reasonable efforts to consummate the exchange offer within 365 days after the issue date of the Notes, and keep the exchange offer open for not less than 20 business days after the date notice of the exchange offer is mailed to the holders of the Notes. You are entitled to exchange in the exchange offer your Outstanding Notes for Exchange Notes which are identical in all material respects to the Outstanding Notes except that the Exchange Notes have been registered under the Securities Act and will not contain terms with respect to transfer restrictions in the United States, and are not entitled to registration rights and additional interest provisions applicable to the Outstanding Notes.

The Exchange Offer | We are offering to exchange up to US$400,000,000 aggregate principal amount of our 5.250% Senior Notes due 2024, which have been registered under the Securities Act, for up to US$400,000,000 aggregate principal amount of our existing 5.250% Senior Notes due 2024. Outstanding Notes may be exchanged only in denominations of US$2,000 and integral multiples of US$1,000 in excess of US$2,000.

Resale | Based on an interpretation by the staff of the SEC set forth in no-action letters issued to third parties, we believe that the Exchange Notes issued pursuant to the exchange offer in exchange for the Outstanding Notes may be offered for resale, resold and otherwise transferred by you (unless you are our “affiliate” within the meaning of Rule 405 under the Securities Act) in the United States without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that:

| • |  | you are acquiring the Exchange Notes in the ordinary course of your business; and

| • |  | you have not engaged in, do not intend to engage in, and have no arrangement or understanding with any person to participate in, a distribution of the Exchange Notes.

| Each broker-dealer that receives Exchange Notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes. The letter of transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes received in exchange for Outstanding Notes where

6

##### Table of Contents

| such Outstanding Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities. Precision has agreed that, for a period of 180 days after the expiration date (as defined herein), it will make this prospectus available to any broker-dealer for use in connection with any such resale. See “Plan of Distribution.”

| Any holder of Outstanding Notes who:

| • |  | is our affiliate;

| • |  | does not acquire Exchange Notes in the ordinary course of its business; or

| • |  | tenders its Outstanding Notes in the exchange offer with the intention to participate, or for the purpose of participating, in a distribution of Exchange Notes;

| cannot rely on the position of the staff of the SEC enunciated in Morgan Stanley & Co. Incorporated (available June 5, 1991) and Exxon Capital Holdings Corporation (available May 13, 1988), as interpreted in Shearman & Sterling (available July 2, 1993), or similar no-action letters and, in the absence of an exemption therefrom, must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale of the Exchange Notes in the United States.

Expiration Date; Withdrawal of Tender | The exchange offer will expire at midnight, New York City time, on , 2015, unless extended by us. We do not currently intend to extend the expiration date. You may withdraw the tender of your Outstanding Notes at any time prior to the expiration of the exchange offer. We will return to you any of your Outstanding Notes that are not accepted for any reason for exchange, without expense to you, promptly after the expiration or termination of the exchange offer.

Interest on the Exchange Notes | The Exchange Notes will accrue interest at a rate of 5.250% per annum. On the first interest payment date following the exchange, holders of Exchange Notes will receive interest for the period from and including the last interest payment date on which interest was paid on the Outstanding Notes. No additional or other interest relating to such period will be paid to such holders.

Conditions to the Exchange Offer . | The exchange offer is subject to customary conditions, which we may waive. See “The Exchange Offer — Conditions to the Exchange Offer” of this prospectus for more information.

Procedures for Tendering Outstanding Notes | If you wish to participate in the exchange offer, you must complete, sign and date the accompanying letter of transmittal according to the

7

##### Table of Contents

| instructions contained in this prospectus and the letter of transmittal. You must then mail or otherwise deliver the letter of transmittal together with your Outstanding Notes and any other required documents, to the exchange agent at the address set forth on the cover page of the letter of transmittal.

| If you hold Outstanding Notes through The Depository Trust Company (“DTC”) and wish to participate in the exchange offer, you must comply with the Automated Tender Offer Program procedures of DTC by which you will agree to be bound by the letter of transmittal. By signing, or agreeing to be bound by, the letter of transmittal, you will represent to us that, among other things:

| • |  | you are not our “affiliate” within the meaning of Rule 405 under the Securities Act;

| • |  | you do not have an arrangement or understanding with any person or entity to participate in the distribution of the Exchange Notes;

| • |  | you are acquiring the Exchange Notes in the ordinary course of your business; and

| • |  | if you are a broker-dealer that will receive Exchange Notes for your own account in exchange for Outstanding Notes that were acquired as a result of market-making activities, you will deliver a prospectus, as required by law, in connection with any resale of such Exchange Notes in the United States.

Special Procedures for Beneficial Owners | If you are a beneficial owner of Outstanding Notes which are registered in the name of a broker, dealer, commercial bank, trust company or other nominee, and you wish to tender such Outstanding Notes in the exchange offer, you should contact such registered holder promptly and instruct such registered holder to tender on your behalf. If you wish to tender on your own behalf, you must, prior to completing and executing the letter of transmittal and delivering your Outstanding Notes, either make appropriate arrangements to register ownership of the Outstanding Notes in your name or obtain a properly completed bond power from the registered holder. The transfer of registered ownership may take considerable time and may not be able to be completed prior to the expiration date.

Guaranteed Delivery Procedures | If you wish to tender your Outstanding Notes and your Outstanding Notes are not immediately available or you cannot deliver your Outstanding Notes, the letter of transmittal or any other required documents, or you cannot comply with the procedures under DTC’s Automated Tender Offer Program for transfer of book-entry interests prior to the expiration date, you must tender your Outstanding Notes according to the guaranteed delivery procedures set forth in this prospectus under “The Exchange Offer — Guaranteed Delivery Procedures.”

##### Table of Contents

Effect on Holders of Outstanding Notes | As a result of the making of, and upon acceptance for exchange of all validly tendered Outstanding Notes pursuant to the terms of the exchange offer, we and the guarantors will have fulfilled a covenant contained in the registration rights agreement and, accordingly, there will be no increase in the interest rate on the Outstanding Notes under the circumstances described in the registration rights agreement. If you are a holder of Outstanding Notes and you do not tender your Outstanding Notes in the exchange offer, you will continue to hold such Outstanding Notes and you will be entitled to all the rights and limitations applicable to the Outstanding Notes as set forth in the indenture governing the notes, except we and the guarantors will not have any further obligations to you to provide for the exchange and registration of untendered Outstanding Notes under the registration rights agreement. To the extent that Outstanding Notes are tendered and accepted in the exchange offer, the trading market, if any, for Outstanding Notes that are not so tendered and accepted could be adversely affected.

Consequences of Failure to Exchange | All untendered Outstanding Notes will continue to be subject to the restrictions on transfer provided for in the Outstanding Notes and in the indenture governing the notes. In general, the Outstanding Notes may not be offered or sold in the United States, unless registered under the Securities Act, except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. Other than in connection with the exchange offer, we and the guarantors do not currently anticipate that we will register the Outstanding Notes under the Securities Act.

Certain Federal Income Tax Consequences | The exchange of Outstanding Notes in the exchange offer will not constitute a taxable event for United States federal income tax purposes and no Canadian federal income tax will be payable in respect of the exchange by a Non-Canadian Holder (as defined under the heading “Certain Canadian Federal Income Tax Considerations”. See “Certain United States Federal Income Tax Considerations” and “Certain Canadian Federal Income Tax Considerations”.

Accounting Treatment | We will record the Exchange Notes in our accounting records at the same carrying value as the Outstanding Notes, which is the aggregate principal amount as reflected in our accounting records on the date of exchange. Accordingly, we will not recognize any gain or loss for accounting purposes upon the consummation of the exchange offer. We will record the expenses of the exchange offer as incurred.

Regulatory Approvals | Other than compliance with the Securities Act and other applicable securities laws and qualification of the indenture governing the notes under the Trust Indenture Act, there are no federal or state regulatory requirements that must be complied with or approvals that must be obtained in connection with the exchange offer.

We may redeem the notes in whole or in part at any time on or after May 15, 2019, at the redemption prices described under the heading “Description of the Exchange Notes — Optional Redemption”, plus accrued and unpaid interest, if any.

Additional Amounts and Redemption for Changes in Canadian Withholding Taxes | Except as required by law, we will make payments on the notes free of withholding or deduction for Canadian taxes. If withholding or deduction for Canadian taxes is required, we will, subject to certain customary exceptions, be required to pay additional amounts so that the net amounts you receive will equal the amount you would have received if withholding or deduction had not been imposed. If, as a result of a change in law occurring on or after the date of the indenture that will govern the notes offered hereby, we are required to pay such additional amounts, we may redeem the notes in whole but not in part, at any time at 100% of their principal amount, plus

10

##### Table of Contents

| accrued and unpaid interest, if any, to the redemption date. See “Description of the Exchange Notes — Payment of Additional Amounts” and “Description of the Exchange Notes — Optional Redemption — Redemption for Changes in Tax Law.”

Change of Control Repurchase | Upon specified change of control events, each holder of a note will have the right to sell to us all or a portion of its notes at a purchase price in cash equal to 101% of the principal amount, plus accrued and unpaid interest, if any, to the date of purchase.

Ranking | The notes are:

| • |  | our senior unsecured obligations;

| • |  | equal in ranking (“pari passu”) with all of our existing and future senior unsecured indebtedness; and

| • |  | senior in right of payment to our future subordinated indebtedness.

| Our secured debt, including borrowings under our revolving credit facility, and all of our other secured obligations in effect from time to time are effectively senior to the notes to the extent of the value of the assets securing such debt or other obligations.

| The notes are effectively subordinated to all existing and future obligations, including indebtedness and trade payables, of any of our subsidiaries that do not guarantee the notes.

| Each guarantee of the notes is:

| • |  | a senior unsecured obligation of that guarantor;

| • |  | pari passu in right of payment with all existing and future senior indebtedness of that guarantor; and

| • |  | senior in right of payment to future subordinated indebtedness of that guarantor.

| Secured debt of that guarantor, including guarantees of borrowings under our revolving credit facility, and all other secured obligations of that guarantor in effect from time to time will be effectively senior to the guarantee to the extent of the value of the assets securing such debt or other obligations.

Certain Covenants | The indenture governing the notes limits our ability and the ability of certain of our subsidiaries to, among other things:

| • |  | incur additional indebtedness and issue preferred stock;

| • |  | create liens;

| • |  | make restricted payments;

| • |  | create or permit to exist restrictions on our ability or the ability of certain of our subsidiaries to make certain payments and distributions;

11

##### Table of Contents

| • |  | engage in amalgamations, mergers or consolidations;

| • |  | make certain dispositions and transfers of assets; and

| • |  | engage in transactions with affiliates.

| These covenants are subject to important exceptions and qualifications, which are described under “Description of the Exchange Notes — Certain Covenants” in this prospectus.

| If the notes receive an investment grade rating by Standard & Poor’s or Moody’s Investors Service and we and our subsidiaries are not in default under the indenture governing the notes, we and our subsidiaries will not be required to comply with particular covenants contained in the indenture. See “Description of the Exchange Notes — Certain Covenants.”

No Prior Market | The Exchange Notes will be new securities for which there is currently no market. Although the initial purchasers in the private offering have informed us that they intend to make a market in the Outstanding Notes and, if issued, in the Exchange Notes, they are not obligated to do so and they may discontinue any market making activities at any time without notice. Accordingly, we cannot assure you that a liquid market for the Outstanding Notes or Exchange Notes will develop or be maintained.

Use of Proceeds | There will be no cash proceeds to us from the exchange offer.

In evaluating an investment in the Exchange Notes, prospective investors should carefully consider, along with the other information in this prospectus and the documents incorporated by reference herein, the specific factors set forth under “Risk Factors” for risks involved with an investment in the Exchange Notes.

12

##### Table of Contents

RISK FACTORS

You should carefully consider the risk factors set forth below as well as the other information contained in this prospectus and the documents incorporated by reference herein before you decide to tender Outstanding Notes in the exchange offer, including, without limitation, the risk factors discussed under the heading “Risk Factors” in the AIF of Precision dated March 14, 2014 for the year ended December 31, 2013 (filed on EDGAR on Form 40-F on March 14, 2014 and incorporated by reference herein). The risks described below are not the only risks that may affect us. Additional risks and uncertainties not currently known to us or those we currently view to be immaterial may also materially and adversely affect our business, financial condition or results of operations. Any of the following risks could materially and adversely affect our business, financial condition or results of operations. In such a case, you may lose all or a part of your investment.

Our substantial indebtedness could adversely affect our financial condition and prevent us from fulfilling our obligations under our revolving credit facility, our existing notes and the notes offered hereby.

Our substantial debt could have a material adverse effect on our financial condition and results of operations as well as our ability to fulfill obligations under our revolving credit facility, our existing notes and the notes offered hereby. In particular, it could:

| • |  | increase our vulnerability to general adverse economic and industry conditions and require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of our cash flow to fund working capital, capital expenditures, acquisitions, other debt service requirements and other general corporate purposes;

| • |  | decrease our ability to satisfy our obligations under our revolving credit facility, our existing notes and the notes offered hereby;

| • |  | increase our vulnerability to covenants relating to our indebtedness which may limit our ability to obtain additional financing for working capital, capital expenditures and other general corporate activities;

| • |  | increase our exposure to risks inherent in interest rate fluctuations and changes in credit ratings or statements from rating agencies because certain of our borrowings (including borrowings under our revolving credit facility) are at variable rates of interest, which would result in higher interest expense to the extent we have not hedged these risks against increases in interest rates;

| • |  | increase our exposure to exchange rate fluctuations because a change in the value of the Canadian dollar against the U.S. dollar will result in an increase or decrease in our U.S. dollar denominated debt, as expressed in Canadian dollars, as well as in the related interest expense;

| • |  | limit our flexibility in planning for, or reacting to, changes in our business or the industry in which we operate;

| • |  | place us at a competitive disadvantage compared to our competitors that have less debt;

| • |  | limit our ability to borrow additional funds to meet our operating expenses, to make acquisitions and for other purposes; and

| • |  | limit our ability to construct, purchase or acquire new rigs.

We may incur substantial additional debt in the future, including additional secured debt. This could further exacerbate the risks associated with our substantial debt.

The notes and guarantees are unsecured and effectively subordinated to our and our subsidiaries’ existing and future secured indebtedness.

Our obligations under the notes are not secured and the guarantors’ obligations under the guarantees are not secured, while our obligations under our revolving credit facility and each guarantor’s obligations under their respective guarantees under our revolving credit facility are secured by substantially all of our tangible and

13

##### Table of Contents

intangible assets, including our shares of our U.S. and Canadian subsidiaries. Therefore, the lenders under our revolving credit facility and holders of any other secured debt that we may incur in the future will have claims with respect to these assets that have priority over the claims of holders of the notes.

In the event that we are declared bankrupt, become insolvent or are liquidated or reorganized, or if there is an event of default under our revolving credit facility, the lenders could declare all of the funds borrowed thereunder, together with accrued interest, to be immediately due and payable and terminate all commitments to extend further credit. If we were unable to repay such indebtedness, the lenders could foreclose or otherwise realize on the pledged assets to the exclusion of holders of the notes, even if an event of default exists under the indenture governing the notes. Furthermore, if the lenders foreclose or otherwise realize upon and sell the pledged equity interests in any guarantor under the notes, then that guarantor will be released from its guarantee of the notes automatically and immediately upon such sale. In any such events, because the notes are not secured by any of our assets or the equity interests in guarantors, it is possible that there would be no assets remaining from which your claims could be satisfied or, if any assets remained, they might be insufficient to satisfy your claims fully.

We need significant amounts of cash to service our indebtedness, including our obligations under the notes. If we are unable to generate a sufficient amount of cash to service our indebtedness, our financial condition and results of operations could be negatively impacted.

We need significant amounts of cash in order to service and repay our indebtedness. Our ability to generate cash in the future will be, to a certain extent, subject to general economic, financial, competitive and other factors that may be beyond our control. In addition, our ability to borrow funds in the future to service our debt, if necessary, will depend on covenants in the indenture that will govern the notes offered hereby, the credit agreement governing our revolving credit facility, the indentures governing our existing notes and other debt agreements we enter into in the future. Future borrowings may not be available to us under our revolving credit facility or from the capital markets in amounts sufficient to enable us to pay our obligations as they mature or to fund other liquidity needs. If we are not able to obtain such borrowings or generate cash flow from operations in an amount sufficient to enable us to service and repay our indebtedness, we will need to refinance our indebtedness or be in default under the agreements governing our indebtedness and could be forced to reduce or delay investments and capital expenditures or to dispose of material assets. Such refinancing or alternative measures may not be available on favorable terms or at all. The inability to service, repay and/or refinance our indebtedness could negatively impact our financial condition and results of operations.

In addition, we conduct a substantial portion of our operations through our subsidiaries, certain of which will not be guarantors of the notes or our other indebtedness. Accordingly, repayment of our indebtedness, including the notes, is dependent on the generation of cash flow by our subsidiaries and their ability to make such cash available to us, by dividend, debt repayment or otherwise. Unless they are guarantors of the notes or our other indebtedness, our subsidiaries do not have any obligation to pay amounts due on the notes or our other indebtedness or to make funds available for that purpose. Our subsidiaries may not be able to, or may not be permitted to, make distributions to enable us to make payments in respect of our indebtedness, including the notes. Each subsidiary is a distinct legal entity, and, under certain circumstances, legal and contractual restrictions may limit our ability to obtain cash from our subsidiaries. While the indenture governing the notes limits, and the agreements governing certain of our other existing indebtedness limit, the ability of our subsidiaries to incur consensual restrictions on their ability to pay dividends or make other intercompany payments to us, these limitations are subject to qualifications and exceptions. In the event that we do not receive distributions from our subsidiaries, we may be unable to make required principal and interest payments on our indebtedness, including the notes.

Our inability to generate sufficient cash flows to satisfy our debt obligations, or to refinance our indebtedness on commercially reasonable terms or at all, would materially and adversely affect our financial position and results of operations and our ability to satisfy our obligations under the notes.

14

##### Table of Contents

If we cannot make scheduled payments on our debt, we will be in default and the holders of the notes could declare all outstanding principal and interest to be due and payable, the holders of our existing notes could declare all outstanding principal and interest on our existing notes to be due and payable, the lenders under our revolving credit facility could declare all amounts outstanding under our revolving credit facility to be due and payable and could terminate their commitments to lend money and foreclose against the assets securing their borrowings and we could be forced into bankruptcy or liquidation. All of these events could result in you losing your investment in the notes.

Despite our current level of indebtedness, we and our subsidiaries may still be able to incur substantially more debt. This could further exacerbate the risks to our financial condition described above.

We and our subsidiaries may be able to incur significant additional indebtedness in the future. Although the indentures governing our existing notes and the credit agreement governing our revolving credit facility contain, and the indenture that will governs the notes contains restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of qualifications and exceptions, and the additional indebtedness incurred in compliance with these restrictions could be substantial. If we incur any additional indebtedness that ranks equally with the notes, subject to collateral arrangements, the holders of that debt will be entitled to share ratably with you in any proceeds distributed in connection with any insolvency, liquidation, reorganization, dissolution or other winding up of our company. These restrictions also will not prevent us from incurring obligations that do not constitute indebtedness. In addition, all future borrowings under our revolving credit agreement would be secured indebtedness and would be effectively senior to the notes to the extent of the value of the assets securing such indebtedness. If new debt is added to our current debt levels, the related risks that we and the guarantors now face could intensify. See “Description of the Exchange Notes”.

Our indebtedness contains restrictive covenants.

The indentures governing our existing notes and the credit agreement governing our revolving credit facility impose, and the indenture that governs the notes imposes, significant operating and financial restrictions on us. These restrictions limit our ability and that of our restricted subsidiaries to, among other things:

| • |  | pay dividends on, repurchase or make distributions in respect of our capital stock or make other restricted payments;

| • |  | incur additional indebtedness and issue preferred or disqualified stock;

| • |  | create liens;

| • |  | create or permit to exist restrictions on the ability of our restricted subsidiaries to make certain payments and distributions;

| • |  | engage in amalgamations, mergers or consolidations or sell or otherwise dispose of all or substantially all of our assets;

| • |  | make certain dispositions and transfers of assets;

| • |  | alter the businesses we conduct;

| • |  | engage in transactions with affiliates; and

| • |  | designate subsidiaries as unrestricted subsidiaries.

In addition, under the credit agreement governing our revolving credit facility, we are required to satisfy and maintain certain financial ratio tests. Our ability to meet such tests could be affected by events beyond our control, and we may not be able to meet such tests. These ratios may be changed by the lenders in certain circumstances.

15

##### Table of Contents

A breach of any of these covenants could result in a default under the credit agreement governing our revolving credit facility, the indentures governing our existing notes or the indenture governing the notes. Upon the occurrence of an event of default under the credit agreement governing our revolving credit facility, the lenders could elect to declare all amounts outstanding under our revolving credit facility to be immediately due and payable and terminate all commitments to extend further credit. Upon the occurrence of an event of default under our existing notes, the noteholders could elect to declare all amounts outstanding under our existing notes to be immediately due and payable. If we are unable to repay those amounts, the lenders under our revolving credit facility could proceed to foreclose or otherwise realize upon the collateral granted to them to secure that indebtedness. If the lenders under our revolving credit facility or the noteholders of our existing notes accelerate the repayment of borrowings, we may not have sufficient assets to repay our revolving credit facility as well as our unsecured indebtedness, including our existing notes and the notes. The acceleration of our indebtedness under one agreement may permit acceleration of indebtedness under other agreements that contain cross-default or cross-acceleration provisions. If our indebtedness is accelerated, we may not be able to repay our indebtedness or borrow sufficient funds to refinance it. Even if we are able to obtain new financing, it may not be on commercially reasonable terms or on terms that are acceptable to us. The restrictions contained in the credit agreement governing our revolving credit facility, the indentures governing our existing notes and the indenture governing the notes may adversely affect our ability to finance our future operations and capital needs and to pursue available business opportunities. Moreover, any new indebtedness we incur may impose financial restrictions and other covenants on us that may be more restrictive than the credit agreement governing our revolving credit facility, the indentures governing our existing notes or the indenture governing the notes.

Our variable rate indebtedness subjects us to interest rate risk, which could cause our debt service obligations to increase significantly.

Borrowings under our revolving credit facility are at variable rates of interest and expose us to interest rate risk. If interest rates increase, our debt service obligations on the variable rate indebtedness will increase even though the amount borrowed remains the same, and our net income and cash flows, including cash available for servicing our indebtedness, will correspondingly decrease. From time to time, we may enter into interest rate swaps that involve the exchange of floating for fixed rate interest payments in order to reduce interest rate volatility. However, we may not maintain interest rate swaps with respect to all of our variable rate indebtedness, and any swaps we enter into may not fully mitigate our interest rate risk.

Claims of noteholders will be structurally subordinated to claims of creditors of our subsidiaries that do not guarantee the notes.

The notes are not guaranteed by any of our non-U.S. and non-Canadian subsidiaries or certain other subsidiaries. Accordingly, claims of holders of the notes are structurally subordinated to the claims of creditors of these non-guarantor subsidiaries, including trade creditors. All obligations of these subsidiaries will have to be satisfied before any of the assets of such subsidiaries would be available for distribution, upon a liquidation or otherwise, to us or creditors of us, including the holders of the notes.

In addition, the indenture that governs the notes, subject to some limitations, permits these subsidiaries to incur additional indebtedness and does not contain any limitation on the amount of other liabilities, such as trade payables, that may be incurred by these subsidiaries.

In addition, our subsidiaries that provide, or will provide, guarantees of the notes will be automatically released from those guarantees upon the occurrence of certain events, including the following:

| • |  | the designation of that guarantor as an unrestricted subsidiary;

| • |  | the release or discharge of any guarantee or indebtedness that resulted in the creation of the guarantee of the notes by such guarantor; or

| • |  | the sale or other disposition, including the sale of substantially all of the assets, of that guarantor.

##### Table of Contents

If any guarantor is released, no holder of the notes will have a claim as a creditor against that subsidiary, and the indebtedness and other liabilities, including trade payables and preferred stock, if any, whether secured or unsecured, of that subsidiary will be effectively senior to the claim of any holders of the notes. See “Description of the Exchange Notes — Guarantees.”

U.S. federal and state statutes (and Canadian federal and provincial statutes) may allow courts, under specific circumstances, to void the guarantees and require noteholders to return payments received from guarantors.

Under U.S. federal bankruptcy law and comparable provisions of state fraudulent transfer laws, a guarantee could be deemed a fraudulent transfer if the guarantor received less than a reasonably equivalent value in exchange for giving the guarantee and:

| • |  | was insolvent on the date that it gave the guarantee or became insolvent as a result of giving the guarantee;

| • |  | was engaged in business or a transaction, or was about to engage in business or a transaction, for which property remaining with the guarantor was an unreasonably small capital; or

| • |  | intended to incur, or believed that it would incur, debts that would be beyond the guarantor’s ability to pay as those debts matured.

Similarly, under Canadian federal bankruptcy law and comparable provisions of provincial fraudulent preference and fraudulent conveyance laws, a guarantee or a payment under a guarantee could be deemed to be a fraudulent preference or fraudulent conveyance, or could be otherwise avoided if:

| • |  | the guarantor becomes bankrupt and was insolvent or on the eve of insolvency at the time the guarantee was given or the payment was made or has an “Initial Bankruptcy Event” as defined in the Bankruptcy and Insolvency Act (Canada) within one year of giving us the guarantee or making the payment under the guarantee;

| • |  | we were a creditor of the guarantor when the guarantee or payment was given; and

| • |  | (1) the guarantee or the payment under the guarantee was found to have been given with a view to giving us a preference over other of the guarantor’s creditors; or (2) the guarantee or the payment under the guarantee has the effect of giving us a preference over any of guarantor’s other creditors (in which case it is subject to a rebuttable presumption that a preference was intended).

A payment under a guarantee could also be deemed a fraudulent preference or conveyance if it is found by a court to have been given with the purpose of hindering, delaying or defrauding any entity to which the guarantor was or became indebted, on or after the date the guarantee was given (and, in the case of fraudulent preferences, if the guarantor was insolvent or on the eve of insolvency at that time). The measures of insolvency for purposes of the foregoing considerations will vary depending upon the law applied in any proceeding with respect to the foregoing. Generally, however, a guarantor would be considered insolvent if:

| • |  | the sum of its debts, including contingent liabilities, is greater than all its assets, at a fair valuation;

| • |  | the present fair saleable value of its assets is less than the amount that would be required to pay its probable liability on its existing debts, including contingent liabilities, as they become absolute and mature; or

| • |  | it could not pay its debts as they become due.

The indenture governing the notes contains a provision intended to limit each guarantor’s liability under its guarantee to the maximum amount that it could incur under applicable laws without causing the guarantee or a payment thereunder to be a fraudulent transfer. This provision may not be effective to protect the guarantees or a payment thereunder from being voided under applicable fraudulent transfer law. If a guarantee is deemed to be a

17

##### Table of Contents

fraudulent transfer it could be voided altogether, or it could be subordinated to all other debts of the guarantor. In such case, any payment by the guarantor pursuant to its guarantee could be required to be returned to the guarantor or to a fund for the benefit of the creditors of the guarantor. If a guarantee is voided or held unenforceable for any other reason, holders of the notes would cease to have a claim against the guarantor based on the guarantee and would be creditors only of us and any guarantor whose guarantee was not similarly voided or otherwise held unenforceable.

Certain bankruptcy and insolvency laws may impair your ability to enforce your rights or remedies under the indenture governing the notes.

Your ability and the rights of the trustee, or any co-trustee, who represents the holders of the notes to enforce your rights or remedies under the indenture governing the notes may be significantly impaired by the provisions of applicable Canadian federal bankruptcy, insolvency and other restructuring legislation or by Canadian federal or provincial receivership laws. For example, the Bankruptcy and Insolvency Act (Canada), the Companies’ Creditors Arrangement Act (Canada) and the Winding-up and Restructuring Act (Canada) contain provisions enabling an insolvent debtor to obtain a stay of proceedings against its creditors and others and to prepare and file a proposal or a plan of arrangement and reorganization for consideration by all or some of its creditors, to be voted on by the various classes of creditors affected thereby. Such a restructuring proposal or arrangement and reorganization, if accepted by the requisite majority of each class of affected creditors and if approved by the relevant Canadian court, would be binding on all creditors of the debtor within the affected classes, including those creditors who vote against such a proposal. Moreover, certain provisions of the relevant Canadian insolvency legislation permit an insolvent debtor to retain possession and administration of its property in certain circumstances, subject to court oversight, even though such debtor may be in default in respect of certain of its obligations during the period that the stay of proceedings remains in place. Further, it is typical in such case for the court to grant priority charges in favor of professionals and other parties involved in the restructuring or similar proceeding.

The powers of the court under Canadian bankruptcy, insolvency and restructuring legislation and Canadian federal and provincial receivership laws, and particularly under the Companies’ Creditors Arrangement Act (Canada), are exercised broadly to protect a debtor and its estate from actions taken by creditors and others. We cannot predict whether payments under the notes would be made during any proceedings in bankruptcy, receivership, insolvency or other restructuring, whether or when you or the trustee, or any co-trustee, could exercise their rights under the indenture governing the notes or whether, and to what extent, the holders of the notes would be compensated for any delays in payment of principal, interest and costs, including fees and disbursements of the trustee, or any co-trustee. Accordingly, if we were to become subject to such proceedings, we may cease making payments on the notes and you and the trustee, or any co-trustee, may not be able to exercise your rights under the indenture governing the notes following commencement of or during such proceedings without leave of the court.

You might have difficulty enforcing your rights against us, certain of the guarantors and our directors and officers.

We and certain of the guarantors are incorporated or otherwise organized under the laws of the province of Alberta, Canada and the federal laws of Canada, as applicable. The majority of our directors and officers and certain of the experts named in this prospectus and the documents incorporated by reference herein reside principally in Canada or otherwise outside the United States. Because we, certain of the guarantors and these persons are located outside the United States, it may not be possible for you to effect service of process within the United States on us or them. Furthermore, it may not be possible for you to enforce against us or them, in the United States, judgments obtained in United States courts, because a substantial portion of our and their assets are located outside the United States. We have been advised by Norton Rose Fulbright Canada LLP, our Canadian counsel, that there is doubt as to the enforceability, in original actions in Canadian courts, of liabilities based on the United States federal securities laws or the securities or “blue sky” laws of any state within the United States and as to the enforceability in Canadian courts of judgments of United States courts obtained in

18

##### Table of Contents

actions based on the civil liability provisions of the United States federal securities laws or any such state securities or blue sky laws. Therefore, it may not be possible to enforce those judgments against us, our directors and officers or some of the experts named in this prospectus or the documents incorporated by reference herein.

We may not have the ability to finance the change of control repurchase offer required by the indenture governing the notes.

Upon certain change of control events, as that term is defined in the indenture governing the notes, including a change of control caused by an unsolicited third party, we will be required to make an offer in cash to repurchase all or any part of each holder’s notes at a price equal to 101% of the aggregate principal amount thereof, plus accrued interest. The source of funds for any such repurchase would be our available cash or cash generated from operations or other sources, including borrowings, sales of equity or funds provided by a new controlling person or entity. We cannot assure you that sufficient funds will be available at the time of any change of control event to repurchase all tendered notes pursuant to this requirement. Our failure to offer to repurchase notes, or to repurchase notes tendered, following a change of control will result in a default under the indenture governing the notes, which could lead to a cross-default under the credit agreement governing our revolving credit facility, the indentures governing our existing notes and under the terms of our other indebtedness. Additionally, we may be prohibited from repurchasing the notes by the terms of our indebtedness. The credit agreement governing our revolving credit facility also provides that a change of control, as defined therein, will be a default that permits the lenders to accelerate the maturity of borrowings thereunder and, if such debt is not repaid, to enforce the security interests in the collateral securing such debt. The indentures governing our existing notes also provide that upon certain change of control events, we will be required to make an offer to repurchase those notes at a price equal to 101% of the aggregate principal amount thereof, plus accrued interest. For further information, see “Description of the Exchange Notes.”

One of the events which would trigger a change of control is a sale of “all or substantially all” of our assets. The phrase “all or substantially all” as used in the definition of “change of control” has not been interpreted under New York law (which is the governing law of the indenture governing the notes) to represent a specific quantitative test. As a consequence, investors may not be able to determine when a change of control has occurred, giving rise to the repurchase obligations under the indenture governing the notes. It is possible, therefore, that there could be a disagreement between us and some or all of the holders of the notes over whether a specific asset sale or sales is a change of control triggering event and that holders of the notes might not receive a change of control offer in respect of that transaction. In addition, in the event the holders of the notes elected to exercise their rights under the indenture governing the notes and we elected to contest such election, there could be no assurance as to how a court interpreting New York law would interpret the phrase “all or substantially all.” In addition, certain important corporate events, such as leveraged recapitalizations that would increase the level of our indebtedness, would not constitute a “change of control” under the indenture governing the notes.

Your ability to transfer the notes may be limited by the absence of an active trading market, and there is no assurance that any active trading market will develop for the notes.

We do not intend to apply for a listing of the Exchange Notes on a securities exchange or on any automated dealer quotation system. There is currently no established market for the Exchange Notes, and we cannot assure you as to the liquidity of markets that may develop for the Exchange Notes, your ability to sell the Exchange Notes or the price at which you would be able to sell the Exchange Notes. If such markets were to exist, the Exchange Notes could trade at prices that may be lower than their principal amount or purchase price depending on many factors, including prevailing interest rates, the market for similar notes, our financial and operating performance and other factors. The initial purchasers in the private offering of the Outstanding Notes have advised us that they intend to make a market with respect to the Exchange Notes as permitted by applicable laws and regulations. However, these initial purchasers are not obligated to do so, and any market making with respect to the Exchange Notes may be discontinued at any time without notice. In addition, such market making activity may be limited during the pendency of the exchange offer or the effectiveness of a shelf registration statement in lieu thereof. Therefore, we cannot assure you that an active market for the Exchange Notes will develop or, if

19

##### Table of Contents

developed, that it will continue. Historically, the market for non-investment grade debt has been subject to disruptions that have caused substantial volatility in the prices of securities similar to the Exchange Notes. The market, if any, for the Exchange Notes may experience similar disruptions and any such disruptions may adversely affect the prices at which you may sell your Exchange Notes.

Certain covenants contained in the indenture that governs the notes will no longer be applicable if the notes are rated investment grade by Moody’s or S&P.

The indenture that governs the notes provides that certain covenants will no longer be applicable if the notes are rated investment grade by either Moody’s or S&P. These covenants restrict, among other things, our ability to pay dividends, incur debt, incur liens, sell assets, enter into transactions with affiliates, enter into business combinations and enter into other transactions. There can be no assurance that the notes will ever be rated investment grade.

However, termination of these covenants would allow us to engage in certain transactions that would not be permitted while these covenants were in force, even if the notes are subsequently downgraded below investment grade. See “Description of the Exchange Notes — Certain Covenants — Covenant Termination.”

Credit ratings will not reflect all risks of an investment in the notes and may change.

Any credit ratings applied to the notes are an assessment of our ability to pay our obligations, including obligations under the notes. Consequently, real or anticipated changes in the credit ratings will generally affect the market value of the notes. We cannot assure you that any credit rating assigned to the notes will remain in effect for any given period of time or that any rating will not be lowered or withdrawn entirely by the relevant rating agency. However, credit ratings will not reflect all risks associated with an investment in the notes. Credit ratings, for example, may not reflect the potential impact of risks related to structure, market or other factors discussed herein on the value of the notes.

USE OF PROCEEDS

We will not receive any cash proceeds from the issuance of the Exchange Notes pursuant to the exchange offer. In consideration for issuing the Exchange Notes as contemplated in this prospectus, we will receive in exchange a like principal amount of Outstanding Notes, the terms of which are identical in all material respects to the Exchange Notes, except that the Exchange Notes are registered under the Securities Act, are not entitled to the registration rights which are applicable to the Outstanding Notes, and are not subject to certain additional interest rate provisions applicable to the Outstanding Notes. The Outstanding Notes surrendered in exchange for the Exchange Notes will be retired and canceled and cannot be reissued. Accordingly, issuance of the Exchange Notes will not result in any material change in our capitalization.

THE EXCHANGE OFFER

Purpose and Effect of the Exchange Offer

We and the guarantors have entered into a registration rights agreement with the initial purchasers of the Outstanding Notes in which we and the guarantors agreed, under some circumstances, to file a registration statement relating to an offer to exchange the Outstanding Notes for Exchange Notes and to use our commercially reasonable efforts to consummate the exchange offer within 365 days after the issue date of the Outstanding Notes and to keep the exchange offer open for at least 20 business days (or longer, if required by the federal securities laws). The Exchange Notes will have terms substantially identical to the Outstanding Notes, except that the Exchange Notes will not contain terms with respect to transfer restrictions in the United States, registration rights and additional interest for failure to observe certain obligations in the registration rights agreement. The Outstanding Notes were issued on June 3, 2014.

Under the circumstances set below, we will use our commercially reasonable efforts to cause the SEC to declare effective a shelf registration statement with respect to the resale of the Outstanding Notes within the time periods specified in the registration rights agreement and to keep such shelf registration statement continuously effective until the earlier of (A) two years from the Issue Date or (B) the date on which all notes registered thereunder are disposed of in accordance therewith. These circumstances include:

(1) applicable interpretations of the staff of the SEC do not permit us to effect this exchange offer; or

(2) for any other reason we do not consummate the exchange offer within 365 days of the issue date of the Outstanding Notes; or

(3) any initial purchaser of the Outstanding Notes shall notify us following consummation of the exchange offer that notes held by it are not eligible to be exchanged for Exchange Notes in the exchange offer; or

(4) certain holders are not eligible to participate in the exchange offer.

Under the registration rights agreement, in the event that (i) the exchange offer registration has not been consummated or, if required in lieu thereof, such shelf registration statement has not become effective or been declared effective by the SEC within the time periods described above, or (iii) if any exchange offer registration statement or shelf registration statement is filed and declared effective but shall thereafter cease to be effective or usable (except as specifically permitted in the registration rights agreement) (each such event referred to in clauses (i) and (ii), a “Registration Default” and each period during which Registration Default has occurred and is continuing, a “Registration Default Period”), then, additional interest shall accrue in a rate equal to 0.25% per annum for the first 90 days of the Registration Default Period, and such rate will increase by an additional 0.25% per annum with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum additional interest rate of 1.00% per annum. A copy of the registration rights agreement has been filed as an exhibit to the registration statement of which this prospectus is a part.

If we fail to comply with certain obligations under the registration rights agreement, we will be required to pay additional interest to holders of the Outstanding Notes.

If you wish to exchange your Outstanding Notes for Exchange Notes in the exchange offer, you will be required to make the following written representations:

| • |  | you are not our affiliate or an affiliate of any guarantor within the meaning of Rule 405 of the Securities Act;

| • |  | you have no arrangement or understanding with any person to participate in a distribution (within the meaning of the Securities Act) of the Exchange Notes in violation of the provisions of the Securities Act;

24

##### Table of Contents

| • |  | you are not engaged in, and do not intend to engage in, a distribution of the Exchange Notes; and

| • |  | you are acquiring the Exchange Notes in the ordinary course of your business.

Each broker-dealer that receives Exchange Notes for its own account in exchange for Outstanding Notes, where the broker-dealer acquired the Outstanding Notes as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes in the United States. See “Plan of Distribution.”

Resale of Exchange Notes

Based on interpretations by the SEC set forth in no-action letters issued to third parties, we believe that you may resell or otherwise transfer Exchange Notes issued in the exchange offer in the United States without complying with the registration and prospectus delivery provisions of the Securities Act if:

| • |  | you are not our affiliate or an affiliate of any guarantor within the meaning of Rule 405 under the Securities Act;

| • |  | you do not have an arrangement or understanding with any person to participate in a distribution of the Exchange Notes;

| • |  | you are not engaged in, and do not intend to engage in, a distribution of the Exchange Notes; and

| • |  | you are acquiring the Exchange Notes in the ordinary course of your business.

If you are our affiliate or an affiliate of any guarantor, or are engaging in, or intend to engage in, or have any arrangement or understanding with any person to participate in, a distribution of the Exchange Notes, or are not acquiring the Exchange Notes in the ordinary course of your business:

| • |  | you cannot rely on the position of the SEC set forth in Morgan Stanley & Co. Incorporated (available June 5, 1991) and Exxon Capital Holdings Corporation (available May 13, 1988), as interpreted in the SEC’s letter to Shearman & Sterling, dated July 2, 1993, or similar no-action letters; and

| • |  | in the absence of an exception from the position stated immediately above, you must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale of the Exchange Notes in the United States.

This prospectus may be used for an offer to resell, resale or other transfer of Exchange Notes only as specifically set forth in this prospectus. With regard to broker-dealers, only broker-dealers that acquired the Outstanding Notes as a result of market-making activities or other trading activities may participate in the exchange offer. Each broker-dealer that receives Exchange Notes for its own account in exchange for Outstanding Notes, where such Outstanding Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of the Exchange Notes in the United States. Please read “Plan of Distribution” for more details regarding the transfer of Exchange Notes.

Terms of the Exchange Offer

On the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal, we will accept for exchange in the exchange offer any Outstanding Notes that are properly tendered and not withdrawn prior to the expiration date. Outstanding Notes may only be tendered in minimum denominations of US$2,000 and integral multiples of US$1,000 in excess of US$2,000. We will issue Exchange Notes in a principal amount identical to Outstanding Notes surrendered in the exchange offer.

The form and terms of the Exchange Notes will be substantially identical to the form and terms of the Outstanding Notes except the Exchange Notes will be registered under the Securities Act, will not bear legends

restricting their transfer in the United States and will not provide for any additional interest upon our failure to fulfill our obligations under the registration rights agreement to complete the exchange offer, or file, and cause to be effective, a registration statement, if required thereby, within the specified time periods described above. The Exchange Notes will evidence the same continuing debt as is evidenced by the Outstanding Notes and will not constitute a new debt. The Exchange Notes will be issued under and entitled to the benefits of the same indenture that authorized the issuance of the Outstanding Notes. Consequently, the Outstanding Notes and the Exchange Notes will be treated as a single class of debt securities under the indenture. For a description of the indenture, see “Description of the Exchange Notes.”

The exchange offer is not conditioned upon any minimum aggregate principal amount of Outstanding Notes being tendered for exchange.

As of the date of this prospectus, US$400 million aggregate principal amount of the 5.250% Senior Notes due 2024 are outstanding. This prospectus and a letter of transmittal are being sent to all registered holders of Outstanding Notes. There will be no fixed record date for determining registered holders of Outstanding Notes entitled to participate in the exchange offer. We intend to conduct the exchange offer in accordance with the provisions of the registration rights agreement, the applicable requirements of the Securities Act, the Exchange Act and other applicable securities laws, and the rules and regulations of the SEC. Outstanding Notes that are not tendered for exchange in the exchange offer will remain outstanding and continue to accrue interest and will be entitled to the rights and benefits the holders have under the indenture relating to the Outstanding Notes and the registration rights agreement, except for any rights under the registration rights agreement that by their terms terminate upon the consummation of the exchange offer.

We will be deemed to have accepted for exchange properly tendered Outstanding Notes when we have given written notice of the acceptance to the exchange agent. The exchange agent will act as agent for the tendering holders for the purposes of receiving the Exchange Notes from us and delivering Exchange Notes to holders. Subject to the terms of the registration rights agreement, we expressly reserve the right to amend or terminate the exchange offer and to refuse to accept for exchange any Outstanding Notes not previously accepted for exchange, upon the occurrence of any of the conditions specified below under “— Conditions to the Exchange Offer.”

If you tender your Outstanding Notes in the exchange offer, you will not be required to pay brokerage commissions or fees or, subject to the instructions in the letter of transmittal, transfer taxes with respect to the exchange of Outstanding Notes. We will pay all charges and expenses, other than certain applicable taxes described below in connection with the exchange offer. It is important that you read “— Fees and Expenses” below for more details regarding fees and expenses incurred in the exchange offer.

Expiration Date, Extensions and Amendments

As used in this prospectus, the term “expiration date” means midnight, New York City time, on, , 2015. However, if we, in our sole discretion, extend the period of time for which the exchange offer is open, the term “expiration date” will mean the latest time and date to which we shall have extended the expiration of the exchange offer.

To extend the period of time during which the exchange offer is open, we will notify the exchange agent of any extension by written notice, followed by notification by press release or other public announcement to the registered holders of the Outstanding Notes no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration date.

We reserve the right, in our sole discretion:

| • |  | to delay accepting for exchange any Outstanding Notes (only in the case that we amend or extend the exchange offer);

26

##### Table of Contents

| • |  | to extend the exchange offer or to terminate the exchange offer and refuse to accept Outstanding Notes not previously accepted if any of the conditions set forth below under “— Conditions to the Exchange Offer” have not been satisfied, by giving written notice of such delay, extension or termination to the exchange agent; and

| • |  | subject to the terms of the registration rights agreement, to amend the terms of the exchange offer in any manner. In the event of a material change in the exchange offer, including the waiver of a material condition, we will extend the offer period, if necessary, so that at least five business days remain in such offer period following notice of the material change.

Any delay in acceptance, extension, termination or amendment will be followed as promptly as practicable by written notice to the registered holders of the Outstanding Notes. If we amend the exchange offer in a manner that we determine to constitute a material change, we will promptly disclose the amendment in a manner reasonably calculated to inform the holders of the Outstanding Notes of that amendment.

Without limiting the manner in which we may choose to make public announcements of any delay in acceptance, extension, termination or amendment of the exchange offer, we will have no obligation to publish, advertise, or otherwise communicate any public announcement, other than by making a timely release to a financial news service.

Conditions to the Exchange Offer

Despite any other term of the exchange offer, we will not be required to accept for exchange, or to issue Exchange Notes in exchange for, any Outstanding Notes and we may terminate or amend the exchange offer as provided in this prospectus prior to the expiration date if in our reasonable judgment:

| • |  | the exchange offer or the making of any exchange by a holder violates any applicable law or interpretation of the SEC; or

| • |  | any action or proceeding has been instituted or threatened in writing in any court or by or before any governmental agency with respect to the exchange offer that, in our judgment, would reasonably be expected to impair our ability to proceed with the exchange offer.

In addition, we will not be obligated to accept for exchange the Outstanding Notes of any holder that has not made to us:

| • |  | the representations described under “— Purpose and Effect of the Exchange Offer,” “— Procedures for Tendering Outstanding Notes” and “Plan of Distribution”; or

| • |  | any other representations as may be reasonably necessary under applicable SEC rules, regulations or interpretations to make available to us an appropriate form for registration of the Exchange Notes under the Securities Act.

We expressly reserve the right at any time or at various times to extend the period of time during which the exchange offer is open. Consequently, we may delay acceptance of any Outstanding Notes by giving written notice of such extension to their holders. We will return any Outstanding Notes that we do not accept for exchange for any reason without expense to their tendering holder promptly after the expiration or termination of the exchange offer.

We expressly reserve the right to amend or terminate the exchange offer and to reject for exchange any Outstanding Notes not previously accepted for exchange, upon the occurrence of any of the conditions of the exchange offer specified above. We will give written notice of any extension, amendment, non-acceptance or termination to the exchange agent and holders of the Outstanding Notes as promptly as practicable. In the case of any extension, such notice will be issued no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration date.

27

##### Table of Contents

These conditions are for our sole benefit, and we may assert them regardless of the circumstances that may give rise to them or waive them in whole or in part at any or at various times prior to the expiration date in our sole discretion. If we fail at any time to exercise any of the foregoing rights, this failure will not constitute a waiver of such rights. Each such right will be deemed an ongoing right that we may assert at any time or at various times prior to the expiration date.

In addition, we will not accept for exchange any Outstanding Notes tendered, and will not issue Exchange Notes in exchange for any such Outstanding Notes, if at such time any stop order is threatened or in effect with respect to the registration statement of which this prospectus constitutes a part or the qualification of the indenture under the Trust Indenture Act of 1939, as amended (the “TIA”).

Interest on the Exchange Notes

The Exchange Notes will accrue interest at the rate of 5.250% per annum. On the first interest payment date following the exchange, holders of Exchange Notes will receive interest for the period from and including the last interest payment date on which interest was paid on the Outstanding Notes; provided that holders of Outstanding Notes who become holders on or after the record date for an interest payment date and who participate in the exchange will receive interest from and including such interest payment date. Interest on the Exchange Notes is payable on May 15 and November 15, beginning on May 15, 2015. No additional or other interest relating to such period will be paid to such holders.

Procedures for Tendering Outstanding Notes

To tender your Outstanding Notes in the exchange offer, you must comply with either of the following:

| • |  | complete, sign and date the letter of transmittal and have the signature(s) on the letter of transmittal guaranteed if required by the letter of transmittal and mail or deliver such letter of transmittal (or a copy thereof if the letter of transmittal does not require a signature guarantee), to the exchange agent at the address set forth below under “— Exchange Agent” prior to the expiration date; or

| • |  | comply with DTC’s Automated Tender Offer Program procedures described below.

In addition, either:

| • |  | the exchange agent must receive certificates for the Outstanding Notes along with the letter of transmittal prior to the expiration date;

| • |  | the exchange agent must receive a timely confirmation of book-entry transfer of the Outstanding Notes into the exchange agent’s account at DTC according to the procedures for book-entry transfer described below and a properly transmitted agent’s message prior to the expiration date; or

| • |  | you must comply with the guaranteed delivery procedures described below.

Your tender, if not withdrawn prior to the expiration date, constitutes an agreement between us and you upon the terms and subject to the conditions described in this prospectus and in the letter of transmittal.

The method of delivery of Outstanding Notes, letter of transmittal and all other required documents to the exchange agent is at your election and risk. We recommend that instead of delivery by mail, you use an overnight or hand delivery service, properly insured. In all cases, you should allow sufficient time to assure timely delivery to the exchange agent before the expiration date. You should not send letters of transmittal or certificates representing Outstanding Notes to us. You may request that your broker, dealer, commercial bank, trust company or nominee effect the above transactions for you.

28

##### Table of Contents

If you are a beneficial owner whose Outstanding Notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and you wish to tender your Outstanding Notes, you should promptly contact the registered holder and instruct the registered holder to tender on your behalf. If you wish to tender the Outstanding Notes yourself, you must, prior to completing and executing the letter of transmittal and delivering your Outstanding Notes, either:

| • |  | make appropriate arrangements to register ownership of the Outstanding Notes in your name; or

| • |  | obtain a properly completed bond power from the registered holder of Outstanding Notes.

The transfer of registered ownership may take considerable time and may not be able to be completed prior to the expiration date. Signatures on the letter of transmittal or a notice of withdrawal, as the case may be, must be guaranteed by a member firm of a registered national securities exchange or of the Financial Industry Regulatory Authority, Inc., a commercial bank or trust company having an office or correspondent in the United States or another “eligible guarantor institution” within the meaning of Rule 17A(d)-15 under the Exchange Act unless the Outstanding Notes surrendered for exchange are tendered:

| • |  | by a registered holder of the Outstanding Notes who has not completed the box entitled “Special Registration Instructions” or “Special Delivery Instructions” on the letter of transmittal; or

| • |  | for the account of an eligible guarantor institution.

If the letter of transmittal is signed by a person other than the registered holder of any Outstanding Notes listed on the Outstanding Notes, such Outstanding Notes must be endorsed or accompanied by a properly completed bond power. The bond power must be signed by the registered holder as the registered holder’s name appears on the Outstanding Notes, and an eligible guarantor institution must guarantee the signature on the bond power.

If the letter of transmittal, any certificates representing Outstanding Notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, those persons should also indicate when signing and, unless waived by us, they should also submit evidence satisfactory to us of their authority to so act.

The exchange agent and DTC have confirmed that any financial institution that is a participant in DTC’s system may use DTC’s Automated Tender Offer Program to tender Outstanding Notes. Participants in the program may, instead of physically completing and signing the letter of transmittal and delivering it to the exchange agent, electronically transmit their acceptance of the exchange by causing DTC to transfer the Outstanding Notes to the exchange agent in accordance with DTC’s Automated Tender Offer Program procedures for transfer. DTC will then send an agent’s message to the exchange agent. The term “agent’s message” means a message transmitted by DTC, received by the exchange agent and forming part of the book-entry confirmation, which states that:

| • |  | DTC has received an express acknowledgment from a participant in its Automated Tender Offer Program that is tendering Outstanding Notes that are the subject of the book-entry confirmation;

| • |  | the participant has received and agrees to be bound by the terms of the letter of transmittal, or in the case of an agent’s message relating to guaranteed delivery, that such participant has received and agrees to be bound by the notice of guaranteed delivery; and

| • |  | we may enforce that agreement against such participant.

DTC is referred to herein as a “book-entry transfer facility.”

##### Table of Contents

Acceptance of Exchange Notes

In all cases, we will promptly issue Exchange Notes for Outstanding Notes that we have accepted for exchange under the exchange offer only after the exchange agent timely receives:

| • |  | Outstanding Notes or a timely book-entry confirmation of such Outstanding Notes into the exchange agent’s account at the book-entry transfer facility; and

| • |  | a properly completed and duly executed letter of transmittal and all other required documents or a properly transmitted agent’s message.

By tendering Outstanding Notes pursuant to the exchange offer, you will represent to us that, among other things:

| • |  | you are not our affiliate or an affiliate of any guarantor within the meaning of Rule 405 under the Securities Act;

| • |  | you do not have an arrangement or understanding with any person or entity to participate in a distribution of the Exchange Notes; and

| • |  | you are acquiring the Exchange Notes in the ordinary course of your business.

In addition, each broker-dealer that is to receive Exchange Notes for its own account in exchange for Outstanding Notes must represent that such Outstanding Notes were acquired by that broker-dealer as a result of market-making activities or other trading activities and must acknowledge that it will deliver a prospectus that meets the requirements of the Securities Act in connection with any resale of the Exchange Notes in the United States. The letter of transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. See “Plan of Distribution.”

We will interpret the terms and conditions of the exchange offer, including the letter of transmittal and the instructions to the letter of transmittal, and will resolve all questions as to the validity, form, eligibility, including time of receipt and acceptance of Outstanding Notes tendered for exchange. Our determinations in this regard will be final and binding on all parties. We reserve the absolute right to reject any and all tenders of any particular Outstanding Notes not properly tendered or to not accept any particular Outstanding Notes if the acceptance might, in our or our counsel’s judgment, be unlawful. We also reserve the absolute right to waive any defects or irregularities as to any particular Outstanding Notes prior to the expiration date.

Unless waived, any defects or irregularities in connection with tenders of Outstanding Notes for exchange must be cured within such reasonable period of time as we determine. Neither we, the exchange agent nor any other person will be under any duty to give notification of any defect or irregularity with respect to any tender of Outstanding Notes for exchange, nor will any of them incur any liability for any failure to give notification. Any Outstanding Notes received by the exchange agent that are not properly tendered and as to which the irregularities have not been cured or waived will be returned by the exchange agent to the tendering holder, unless otherwise provided in the letter of transmittal, promptly after the expiration date.

Book-Entry Delivery Procedures

Promptly after the date of this prospectus, the exchange agent will establish an account with respect to the Outstanding Notes at DTC, as the book-entry transfer facility, for purposes of the exchange offer. Any financial institution that is a participant in the book-entry transfer facility’s system may make book-entry delivery of the Outstanding Notes by causing the book-entry transfer facility to transfer those Outstanding Notes into the exchange agent’s account at the facility in accordance with the facility’s procedures for such transfer. To be timely, book-entry delivery of Outstanding Notes requires receipt of a confirmation of a book-entry transfer, a “book-entry confirmation,” and an agent’s message prior to the expiration date, or the guaranteed delivery

30

##### Table of Contents

procedure described below must be complied with. Book-entry tenders will not be deemed made until the book-entry confirmation and agent’s message are received by the exchange agent. Delivery of documents to the book-entry transfer facility does not constitute delivery to the exchange agent.

Holders of Outstanding Notes who are unable to deliver confirmation of the book-entry tender of their Outstanding Notes into the exchange agent’s account at the book-entry transfer facility or all other documents required by the letter of transmittal to the exchange agent on or prior to the expiration date may tender their Outstanding Notes according to the guaranteed delivery procedures described below.

Guaranteed Delivery Procedures

If you wish to tender your Outstanding Notes but your Outstanding Notes are not immediately available or you cannot deliver your Outstanding Notes, the letter of transmittal or any other required documents to the exchange agent or comply with the procedures under DTC’s Automatic Tender Offer Program in the case of Outstanding Notes, prior to the expiration date, you may still tender if:

| • |  | the tender is made through an eligible guarantor institution;

| • |  | prior to the expiration date, the exchange agent receives from such eligible guarantor institution either a properly completed and duly executed notice of guaranteed delivery, by facsimile transmission (if the notice of guaranteed delivery does not require a signature guarantee), mail, or hand delivery or a properly transmitted agent’s message, that (1) sets forth your name and address, the certificate number(s) of such Outstanding Notes and the principal amount of Outstanding Notes tendered; (2) states that the tender is being made thereby; and (3) guarantees that, within three New York Stock Exchange trading days after the expiration date, the letter of transmittal, or copy thereof, together with the Outstanding Notes, and any other documents required by the letter of transmittal, or a book-entry confirmation and an agent’s message will be deposited by the eligible guarantor institution with the exchange agent; and

| • |  | the exchange agent receives the properly completed and executed letter of transmittal or copy (if the letter of transmittal does not require a signature guarantee) thereof and all other documents required by the letter of transmittal, as well as certificate(s) representing all tendered Outstanding Notes in proper form for transfer or a book-entry confirmation of transfer of the Outstanding Notes into the exchange agent’s account at DTC and agent’s message within three New York Stock Exchange trading days after the expiration date.

Upon request, the exchange agent will send to you a notice of guaranteed delivery if you hold certificated notes and you wish to tender your Outstanding Notes according to the guaranteed delivery procedures.

Withdrawal Rights

Except as otherwise provided in this prospectus, you may withdraw your tender of Outstanding Notes at any time prior to midnight, New York City time, on the expiration date.

For a withdrawal to be effective:

| • |  | the exchange agent must receive a written notice of withdrawal at its address set forth below under “— Exchange Agent”, such notice of withdrawal may be delivered by mail or hand delivery or by facsimile transmission (if no medallion guarantee of signatures is required); or

| • |  | you must comply with the appropriate procedures of DTC’s Automated Tender Offer Program system.

Any notice of withdrawal must:

| • |  | specify the name of the person who tendered the Outstanding Notes to be withdrawn;

31

##### Table of Contents

| • |  | identify the Outstanding Notes to be withdrawn, including the certificate numbers and principal amount of the Outstanding Notes; and

| • |  | where certificates for Outstanding Notes have been transmitted, specify the name in which such Outstanding Notes were registered, if different from that of the withdrawing holder.

If certificates for Outstanding Notes have been delivered or otherwise identified to the exchange agent, then, prior to the release of such certificates, you must also submit the serial numbers of the particular certificates to be withdrawn and the signatures in the notice of withdrawal must be guaranteed by an eligible institution unless you are an eligible guarantor institution.

If Outstanding Notes have been tendered pursuant to the procedures for book-entry transfer described above, any notice of withdrawal must specify the name and number of the account at the book-entry transfer facility to be credited with the withdrawn Outstanding Notes and otherwise comply with the procedures of the facility. We will determine all questions as to the validity, form and eligibility, including time of receipt of notices of withdrawal, and our determination will be final and binding on all parties. Any Outstanding Notes so withdrawn will be deemed not to have been validly tendered for exchange for purposes of the exchange offer. Any Outstanding Notes that have been tendered for exchange but that are not exchanged for any reason will be returned to their holder, without cost to the holder, or, in the case of book-entry transfer, the Outstanding Notes will be credited to an account at the book-entry transfer facility, promptly after withdrawal, rejection of tender or termination of the exchange offer. Properly withdrawn Outstanding Notes may be retendered by following the procedures described under “— Procedures for Tendering Outstanding Notes” above at any time on or prior to the expiration date.

Exchange Agent

The Bank of New York Mellon has been appointed as the exchange agent for the exchange offer. You should direct all executed letters of transmittal and any notices of guaranteed delivery and all questions and requests for assistance, requests for additional copies of this prospectus or of the letter of transmittal and requests for notices of guaranteed delivery to the exchange agent addressed as follows:

By Registered or Certified Mail: The Bank of New York Mellon Corporate Trust Operations — Reorganization Unit 111 Sanders Creek Pkwy East Syracuse, NY 13057 Attn: Dacia Brown-Jones Telephone: 315-414-3349 |  | By Regular Mail: The Bank of New York Mellon Corporate Trust Operations — Reorganization Unit 111 Sanders Creek Pkwy East Syracuse, NY 13057 Attn: Dacia Brown-Jones Telephone: 315-414-3349 By Facsimile Transmission (eligible institutions only): 732-667-9408 |  | By Overnight Courier or Hand Delivery: The Bank of New York Mellon Corporate Trust Operations — Reorganization Unit 111 Sanders Creek Pkwy East Syracuse, NY 13057 Attn: Dacia Brown-Jones Telephone: 315-414-3349

If you deliver the letter of transmittal or the notice of guaranteed delivery to an address other than the one set forth above or transmit instructions via facsimile (if the letter of transmittal or the notice of guaranteed delivery does not require a signature guarantee) to a number other than the one set forth above, that delivery or those instructions will not be effective.

Fees and Expenses

The registration rights agreement provides that we will bear all expenses in connection with the performance of our obligations relating to the registration of the Exchange Notes and the conduct of the exchange offer. These expenses include registration and filing fees, accounting and legal fees and printing costs, among

32

##### Table of Contents

others. We will pay the exchange agent reasonable and customary fees for its services and reasonable out-of-pocket expenses as well as the reasonable fees and expenses of its counsel. We will also reimburse brokerage houses and other custodians, nominees and fiduciaries for customary mailing and handling expenses incurred by them in forwarding this prospectus and related documents to their clients that are holders of Outstanding Notes and for handling or tendering for such clients.

We have not retained any dealer-manager in connection with the exchange offer and will not pay any fee or commission to any broker, dealer, nominee or other person, other than the exchange agent, for soliciting tenders of Outstanding Notes pursuant to the exchange offer.

Accounting Treatment

We will record the Exchange Notes in our accounting records at the same carrying value as the Outstanding Notes, which is the aggregate principal amount as reflected in our accounting records on the date of exchange. Accordingly, we will not recognize any gain or loss for accounting purposes upon the consummation of the exchange offer. We will record the expenses of the exchange offer as incurred.

Transfer Taxes

We will pay all transfer taxes, if any, applicable to the exchange of Outstanding Notes under the exchange offer. The tendering holder, however, will be required to pay any transfer taxes, whether imposed on the registered holder or any other person, if:

| • |  | certificates representing Outstanding Notes for principal amounts not tendered or accepted for exchange are to be delivered to, or are to be issued in the name of, any person other than the registered holder of Outstanding Notes tendered;

| • |  | tendered Outstanding Notes are registered in the name of any person other than the person signing the letter of transmittal; or

| • |  | a transfer tax is imposed for any reason other than the exchange of Outstanding Notes under the exchange offer.

If satisfactory evidence of payment of such taxes is not submitted with the letter of transmittal, the amount of such transfer taxes will be billed to that tendering holder.

Holders who tender their Outstanding Notes for exchange will not be required to pay any transfer taxes. However, holders who instruct us to register Exchange Notes in the name of, or request that Outstanding Notes not tendered or not accepted in the exchange offer be returned to, a person other than the registered tendering holder will be required to pay any applicable transfer tax.

Consequences of Failure to Exchange

If you do not exchange your Outstanding Notes for Exchange Notes under the exchange offer, your Outstanding Notes will remain subject to the restrictions on transfer of such Outstanding Notes:

| • |  | as set forth in the legend(s) printed on the Outstanding Notes as a consequence of the issuance of the Outstanding Notes pursuant to the exemption from, or in transactions not subject to, the registration requirements of the Securities Act and/or applicable state and other securities laws; and

| • |  | as otherwise set forth in the offering circular distributed in connection with the private offering.

In general, you may not offer or sell your Outstanding Notes in the United States unless they are registered under the Securities Act or if the offer or sale is exempt from registration under the Securities Act and applicable state securities laws. Except as required by the registration rights agreement, we do not intend to register resales of the Outstanding Notes under the Securities Act.

Other

Participating in the exchange offer is voluntary, and you should carefully consider whether to accept. You are urged to consult your financial and tax advisors in making your own decision on what action to take.

We may in the future seek to acquire untendered Outstanding Notes in open market or privately negotiated transactions, through subsequent exchange offers or otherwise. We have no present plans to acquire any Outstanding Notes that are not tendered in the exchange offer or to file a registration statement to permit resales of any untendered Outstanding Notes.

DESCRIPTION OF THE EXCHANGE NOTES

Precision Drilling Corporation issued the Outstanding Notes, and will issue the Exchange Notes, described in this prospectus under an Indenture dated as of June 3, 2014 (the “Indenture”), among the Issuer, the Guarantors, The Bank of New York Mellon, as trustee (the “U.S. Trustee”) and Valiant Trust Company, as Canadian co-trustee (the “Canadian Trustee” and, together with the U.S. Trustee, the “Trustee”). The term “Notes” refers to the Outstanding Notes and the Exchange Notes. Except as set forth herein, the terms of the Notes are substantially identical and include those set forth in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. You may obtain a copy of the Indenture or the Registration Rights Agreement from the Issuer at its address set forth elsewhere in this prospectus.

The following is a summary of the material terms and provisions of the Notes and the Indenture. The following summary does not purport to be a complete description of the Notes and the Indenture, and is subject to the detailed provisions of, and qualified in its entirety by reference to, the Notes and the Indenture. You can find definitions of certain terms used in this description under the heading “— Certain Definitions.” References to “US$” are to U.S. dollars and to “C$” are to Canadian dollars. The Notes will be denominated in U.S. dollars and all payments on the Notes will be made in U.S. dollars.

Principal, Maturity and Interest

The Notes will mature on November 15, 2024. The Notes bear interest at the rate shown on the cover page of this prospectus, payable in cash semi-annually in arrears on May 15 and November 15 of each year to Holders of record at the close of business on May 1 or November 1, as the case may be (whether or not a Business Day), immediately preceding the related interest payment date. Interest on the Exchange Notes will accrue from and including the most recent date to which interest has been paid on the Outstanding Notes surrendered in exchange therefor or, if no interest has been paid on such Outstanding Notes, from and including the date of issuance of such Outstanding Notes; provided that if Outstanding Notes are surrendered for exchange on or after a record date for an interest payment date that will occur on or after the date of such exchange and as to which interest will be paid, interest on the Exchange Notes received in exchange therefor will accrue from the date of such interest payment date. Interest on the Notes will be computed on the basis of a 360-day year of twelve 30-day months.

If an interest payment date falls on a day that is not a Business Day, the interest payment to be made on such interest payment date will be made on the next succeeding Business Day with the same force and effect as if made on such interest payment date, and no additional interest will accrue solely as a result of such delayed payment. Interest on overdue principal and interest will accrue at the applicable interest rate on the Notes.

The Notes are issued in registered form, without coupons, and in denominations of US$2,000 and integral multiples of US$1,000 in excess thereof.

An aggregate principal amount of Outstanding Notes equal to US$400.0 million was issued in a private transaction that was not subject to the registration requirements of the Securities Act. The Issuer may issue additional Notes having identical terms and conditions to the Notes, except for issue date, issue price and first interest payment date, in an unlimited aggregate principal amount (the “Additional Notes”), subject to compliance with the covenant described under “— Certain Covenants — Limitation on Additional Indebtedness.” Any Additional Notes will be part of the same issue as the Notes and will be treated as one class with the Notes, including for purposes of voting, redemptions and offers to purchase. For purposes of this “Description of the Exchange Notes,” except for the covenant described under “— Certain Covenants —Limitation on Additional Indebtedness,” references to the Notes include Additional Notes, if any.

Payment of Additional Amounts

All payments made by or on behalf of the Issuer under or with respect to the Notes or by or on behalf of any Guarantor pursuant to its Guarantee, will be made without withholding or deduction for or on account of any taxes imposed or levied by or on behalf of any Canadian taxing authority, unless required by law or the interpretation or administration thereof. If the Issuer or a Guarantor is obligated to withhold or deduct any amount on account of taxes imposed by any Canadian taxing authority from any payment made with respect to the Notes, the Issuer or such Guarantor will:

(1) make such withholding or deduction;

(2) remit the full amount deducted or withheld to the relevant government authority in accordance with the applicable law;

(3) subject to the limitations below, pay to each Holder, as additional interest, such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by each Holder (including Additional Amounts) after such withholding or deduction will not be less than the amount such Holder would have received if such taxes had not been withheld or deducted;

(4) make commercially reasonable efforts to obtain and furnish to the Trustee for the benefit of the Holders, within 60 days after the date payment of any taxes is due pursuant to applicable law, certified copies of an official receipt of the relevant government authorities for all amounts deducted or withheld pursuant to applicable law, or if such receipts are not obtainable, other evidence of payment by the Issuer or such Guarantor of those taxes; and

(5) at least 15 days prior to each date on which any Additional Amounts are payable, deliver to the Trustee an Officer’s Certificate setting forth the calculation of the Additional Amounts to be paid and such other information as the U.S. Trustee may request to enable the U.S. Trustee to pay such Additional Amounts to Holders on the payment date.

Notwithstanding the foregoing, none of the Issuer or a Guarantor will pay Additional Amounts with respect to a payment made to any Holder or beneficial owner of a Note (an “Excluded Holder”):

(1) with which the Issuer or such Guarantor does not deal at arm’s length (within the meaning of the Income Tax Act (Canada)) at the time of making such payment;

(2) which is subject to such taxes by reason of the Holder or the beneficial owner being a resident, domicile or national of, or engaged in business or maintaining a permanent establishment or other physical presence in or otherwise having some present or former connection with, Canada or any province or territory thereof otherwise than by the mere acquisition, holding, enforcement or disposition of the Notes or the receipt of payments thereunder;

(3) for or on account of any taxes imposed or deducted or withheld by reason of the failure of the Holder or beneficial owner of the Notes to complete, execute and deliver to the Issuer or a Guarantor, as the case may be, any form or document, to the extent applicable to such Holder or beneficial owner, that may be required by law (including any applicable tax treaty) or by reason of administration of such law and which is reasonably requested in writing to be delivered to the Issuer or such Guarantor in order to enable the Issuer or such Guarantor to make payments on the Notes or pursuant to any Guarantee, as the case may be, without deduction or withholding for taxes, or with deduction or withholding of a lesser amount, which form or document shall be delivered within 60 days of a written request therefor by the Issuer or such Guarantor;

(4) for or on account of any estate, inheritance, gift, sales, transfer, capital gains, excise, personal property or similar tax, assessment or other governmental charge;

(5) for or on account of any tax, duty, assessment or other governmental charge that is payable otherwise than by withholding from payments under or with respect to the Notes (other than taxes payable pursuant to Regulation 803 of the Income Tax Act (Canada), or any similar successor provision);

(6) where the payment could have been made without deduction or withholding if the beneficiary of the payment had presented the Note for payment within 30 days after the date on which such payment or such Note became due and payable or the date on which payment thereof is duly provided for, whichever is later;

(7) if the Holder is a fiduciary, partnership or person other than the sole beneficial owner of that payment, to the extent that such payment would be required to be included in income under the laws of the relevant taxing jurisdiction for tax purposes, of a beneficiary or settler with respect to the fiduciary, a member of that partnership or a beneficial owner who would not have been entitled to such Additional Amounts had that beneficiary, settler, partner or beneficial owner been the Holder thereof;

(8) that is a “specified non-resident shareholder” of the Issuer or such Guarantor or a non-resident person who does not deal at arm’s length with a specified shareholder of the Issuer, both for the purposes of subsection 18(5) of the Income Tax Act (Canada);

(9) in respect of amounts imposed as a result of the failure of the Holder or beneficial owner to properly comply with their obligations imposed under the Income Tax Act (Canada) as a result of the Canada United States Enhanced Tax Information Exchange Agreement Implementation Act (Canada); or

(10) any combination of items (1) through (9) above.

Any reference in the Indenture to the payment of principal, premium, if any, interest, purchase price, redemption price or any other amount payable under or with respect to any Note, will be deemed to include the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. The Issuer’s and the Guarantors’ obligation to make payments of Additional Amounts will survive any termination of the Indenture or the defeasance of any rights thereunder.

The Issuer and each Guarantor, jointly and severally, will indemnify and hold harmless each Holder (other than an Excluded Holder) and upon written request reimburse each such Holder for the amount of (x) any Canadian taxes so levied or imposed and paid by such Holder as a result of payments made under or with respect to the Notes, and (y) any Canadian taxes levied or imposed and paid by such Holder with respect to any reimbursement under (x) above, but excluding any such taxes with respect to which such Holder is an Excluded Holder.

Methods of Receiving Payments on the Notes

If a Holder has given wire transfer instructions to the U.S. Trustee at least ten Business Days prior to the applicable payment date, the Issuer will make all payments on such Holder’s Notes by wire transfer of immediately available funds to the account in New York specified in those instructions. Otherwise, payments on the Notes will be made at the office or agency of the paying agent (the “Paying Agent”) and registrar (the “Registrar”) for the Notes within the City and State of New York unless the Issuer elects to make interest payments by check mailed to the Holders at their addresses set forth in the register of Holders. The Issuer has initially designated the U.S. Trustee in New York, New York to act as Paying Agent and Registrar. The Issuer may change the Paying Agent or Registrar without prior notice to the Holders, and the Issuer and/or any Restricted Subsidiary may act as Paying Agent or Registrar.

Ranking

The Notes are senior unsecured obligations of the Issuer. The Notes rank senior in right of payment to all future obligations of the Issuer that are, by their terms, expressly subordinated in right of payment to the Notes and equal in right of payment with all existing and future obligations of the Issuer that are not so subordinated (including the Existing Notes). Each Guarantee is a general unsecured obligation of the applicable Guarantor and ranks senior in right of payment to all future obligations of such Guarantor that are, by their terms, expressly subordinated in right of payment to the applicable Guarantee and equal in right of payment with all existing and future senior obligations of such Guarantor that are not so subordinated (including such Guarantor’s guarantee of the Existing Notes).

37

##### Table of Contents

The Notes and each Guarantee are effectively subordinated to secured Indebtedness of the Issuer and the applicable Guarantor to the extent of the value of the assets securing such Indebtedness. The Credit Agreement is secured by substantially all of the assets of the Issuer and its material U.S. and Canadian Subsidiaries and, if necessary in order to adhere to covenants in the Credit Agreement, will be secured by certain assets of certain Subsidiaries organized in a jurisdiction outside of the United States or Canada.

The Notes are effectively subordinated to all existing and future obligations, including Indebtedness and trade payables, of any Subsidiaries of the Issuer that do not guarantee the Notes, including any Unrestricted Subsidiaries. Claims of creditors of these Subsidiaries, including trade creditors, generally have priority as to the assets of these Subsidiaries over the claims of the Issuer and the holders of Indebtedness of the Issuer and its other Subsidiaries, including the Notes.

Although the Indenture contains limitations on the amount of additional secured Indebtedness that the Issuer and the Restricted Subsidiaries may incur, under certain circumstances, the amount of this Indebtedness could be substantial. See “— Certain Covenants — Limitation on Additional Indebtedness” and “— Certain Covenants — Limitation on Liens.”

Guarantees

The Issuer’s obligations under the Notes and the Indenture are unconditionally, jointly and severally guaranteed, on a senior unsecured basis, by each U.S. or Canadian Restricted Subsidiary that guarantees any Indebtedness of the Issuer or any Guarantor under a Credit Facility or under debt securities issued in the capital markets (including the Existing Notes), except for any such Subsidiary if the Fair Market Value of the assets of such Subsidiary together with the Fair Market Value of the assets of any other Subsidiaries that guaranteed such Indebtedness of the Issuer or any Guarantor but did not guarantee the Notes, does not exceed US$20.0 million in the aggregate, and each other Restricted Subsidiary that the Issuer shall otherwise cause to become a Guarantor pursuant to the terms of the Indenture. The Guarantors have agreed to pay, in addition to the amount stated above, any and all costs and expenses (including reasonable counsel fees and expenses) incurred by the Trustee or the Holders in enforcing any rights under the Guarantees.

Not all of the Issuer’s Subsidiaries will guarantee the Notes. In the event of a bankruptcy, liquidation or reorganization of any of these non-Guarantor Subsidiaries, the non-Guarantor Subsidiaries will pay the holders of their debt and their trade creditors before they will be able to distribute any of their assets to the Issuer.

As of the Issue Date, all of the Issuer’s Subsidiaries were “Restricted Subsidiaries.” However, under the circumstances described below under the subheading “— Certain Covenants — Limitation on Designation of Unrestricted Subsidiaries,” the Issuer will be permitted to designate any of the Issuer’s Subsidiaries as “Unrestricted Subsidiaries.” The effect of designating a Subsidiary as an “Unrestricted Subsidiary” will be that:

(1) an Unrestricted Subsidiary will not be subject to any of the restrictive covenants in the Indenture;

(2) an Unrestricted Subsidiary will not guarantee the Notes;

(3) a Subsidiary that has previously been a Guarantor and that is designated an Unrestricted Subsidiary will be released from its Guarantee and its obligations under the Indenture and the Registration Rights Agreement; and

(4) the assets, income, cash flows and other financial results of an Unrestricted Subsidiary will not be consolidated with those of the Issuer for purposes of calculating compliance with the restrictive covenants contained in the Indenture.

The obligations of each Guarantor under its Guarantee are limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor (including, without limitation, any guarantees under the Credit Agreement and the Existing Notes) and after giving effect to any collections from or

38

##### Table of Contents

payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to its contribution obligations under the Indenture, result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent conveyance, fraudulent preference, transfer at undervalue, or fraudulent transfer or otherwise reviewable transaction under applicable law. Nonetheless, in the event of the bankruptcy, insolvency or financial difficulty of a Guarantor, such Guarantor’s obligations under its Guarantee may be subject to review and avoidance under applicable fraudulent conveyance, fraudulent preference, fraudulent transfer and insolvency laws. Among other things, such obligations may be avoided if a court concludes that such obligations were incurred for less than a reasonably equivalent value or fair or sufficient consideration at a time when the Guarantor was insolvent, was rendered insolvent, was on the eve of insolvency or was left with inadequate capital to conduct its business, or were incurred with the intent to defraud, defeat, or delay a creditor of the Guarantor or prefer the Issuer over a creditor of the Guarantor. A court may conclude that a Guarantor did not receive reasonably equivalent value or fair or sufficient consideration to the extent that the aggregate amount of its liability on its Guarantee exceeds the economic benefits it receives from the issuance of the Guarantee. If a Guarantee was rendered voidable, it could be subordinated by a court to all other indebtedness (including guarantees and other contingent liabilities) of the Guarantor, and, depending on the amount of such indebtedness, a Guarantor’s liability on its Guarantee could be reduced to zero. See “Risk Factors — Risks Related to the Notes — U.S. federal and state statutes (and Canadian federal and provincial statutes) may allow courts, under specific circumstances, to void the guarantees and require noteholders to return payments received from guarantors.”

Each Guarantor that makes a payment for distribution under its Guarantee is entitled upon payment in full of all guaranteed obligations under the Indenture to a contribution from each other Guarantor in a pro rata amount of such payment based on the respective net assets of all the Guarantors at the time of such payment in accordance with IFRS.

A Guarantor shall be released from its obligations under its Guarantee and its obligations under the Indenture and the Registration Rights Agreement upon:

(1) (a) any sale, exchange or transfer (by merger, amalgamation, consolidation or otherwise) of the Equity Interests of such Guarantor after which the applicable Guarantor is no longer a Restricted Subsidiary, which sale, exchange or transfer is made in compliance with the applicable provisions of the Indenture;

(b) the proper designation of any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary;

(c) the release or discharge of a Guarantor’s guarantee of Indebtedness outstanding under the Credit Agreement and any other agreements relating to Indebtedness of the Issuer and its Restricted Subsidiaries (including the Existing Indentures); provided that such Guarantor has not incurred any Indebtedness in reliance on its status as a Guarantor under the covenant “— Certain Covenants — Limitation on Additional Indebtedness” or such Guarantor’s obligations under such Indebtedness are satisfied in full and discharged or are otherwise permitted to be incurred by a Restricted Subsidiary (other than a Guarantor) under the second paragraph of “— Certain Covenants — Limitation on Additional Indebtedness”; or

(d) legal defeasance or satisfaction and discharge of the Indenture as provided below under the captions “— Legal Defeasance and Covenant Defeasance” and “Satisfaction and Discharge”; and

(2) the Issuer delivering to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for in the Indenture relating to the release of such Guarantor’s Guarantee have been complied with.

Optional Redemption

General

Except as set forth below, the Issuer is not entitled to redeem the Notes at its option prior to May 15, 2019.

At any time or from time to time on or after May 15, 2019, the Issuer, at its option, may redeem the Notes, in whole or in part, at the redemption prices (expressed as percentages of principal amount of the Notes to be redeemed) set forth below, together with accrued and unpaid interest and Additional Interest thereon, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period beginning on May 15 of the years indicated:

Year |  | Optional redemption price |
2019 |  |  | 102.625 | %
2020 |  |  | 101.750 | %
2021 |  |  | 100.875 | %
2022 and thereafter |  |  | 100.000 | %

Redemption with Proceeds from Equity Offerings

At any time or from time to time prior to May 15, 2017, the Issuer, at its option, may on any one or more occasions redeem up to 35.0% of the principal amount of the outstanding Notes issued under the Indenture (calculated after giving effect to any issuance of Additional Notes) with the net cash proceeds of one or more Qualified Equity Offerings at a redemption price equal to 105.250% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest and Additional Interest thereon, if any, to the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided that:

(1) at least 65.0% of the aggregate principal amount of Notes issued under the Indenture (calculated after giving effect to any issuance of Additional Notes) remains outstanding (unless all of such Notes are redeemed or repurchased pursuant to another provision of the Indenture) immediately after giving effect to any such redemption; and

(2) the redemption occurs not more than 90 days after the date of the closing of any such Qualified Equity Offering.

Redemption at Applicable Premium

The Notes may also be redeemed, in whole or in part, at any time prior to May 15, 2019 at the option of the Issuer, at a redemption price equal to 100.0% of the principal amount of the Notes redeemed plus the Applicable Premium (calculated by the Issuer) as of, and accrued and unpaid interest and Additional Interest, if any, to, the applicable redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date). “Applicable Premium” means, with respect to any Note on any applicable redemption date, the greater of:

(1) 1.0% of the principal amount of such Note; and

(2) the excess, if any, of:

(a) the present value at such redemption date of (i) the redemption price of such Note at May 15, 2019 (such redemption price being set forth in the table appearing above under the caption “— Optional Redemption — General”) plus (ii) all required interest payments (excluding accrued and unpaid interest to such redemption date) due on such Note through May 15, 2019, computed using a discount rate equal to the Treasury Rate as of such redemption date plus 50 basis points; over

(b) the principal amount of such Note.

40

##### Table of Contents

Calculation of the Applicable Premium will be made by the Issuer or on behalf of the Issuer by such Person as the Issuer shall designate; provided that such calculation or the correctness thereof shall not be a duty or obligation of the Trustee.

“Treasury Rate” means, as of any redemption date, the yield to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) which has become publicly available at least two Business Days prior to the redemption date (or, if such Statistical Release is no longer published, any publicly available source or similar market data)) most nearly equal to the period from the redemption date to May 15, 2019; provided, however, that if the period from the redemption date to May 15, 2019 is not equal to the constant maturity of a United States Treasury security for which a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for which such yields are given, except that if the period from the redemption date to May 15, 2019 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used.

The Issuer may acquire Notes by means other than a redemption, whether pursuant to a tender offer, open market purchase, negotiated transactions or otherwise, in accordance with applicable securities laws, so long as such acquisition does not otherwise violate the terms of the Indenture.

Redemption for Changes in Tax Law

If the Issuer or a Guarantor becomes obligated to pay any Additional Amounts as a result of a change in the laws or regulations of Canada or any Canadian taxing authority, or a change in any official position regarding the application or interpretation thereof (including a holding by a court of competent jurisdiction), which is publicly announced or becomes effective on or after the date of the Indenture and such Additional Amounts cannot (as certified in an Officer’s Certificate to the Trustee) be avoided by the use of reasonable measures available to the Issuer or any Guarantor, then the Issuer may, at its option, redeem the Notes, in whole but not in part, upon not less than 30 nor more than 60 days’ notice (such notice to be provided not more than 90 days before the next date on which it or the Guarantor would be obligated to pay Additional Amounts), at a redemption price equal to 100.0% of the principal amount thereof, plus accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date). Notice of the Issuer’s intent to redeem the Notes shall not be effective until such time as it delivers to the Trustee an Opinion of Counsel stating that the Issuer or a Guarantor is obligated to pay Additional Amounts because of an amendment to or change in law or regulation or position as described in this paragraph.

Selection and Notice of Redemption

In the event that less than all of the Notes are to be redeemed at any time pursuant to an optional redemption, the U.S. Trustee will select the Notes for redemption in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not then listed on a national security exchange, on a pro rata basis, by lot or by such method as the U.S. Trustee in its sole discretion shall deem fair and appropriate; provided, however, that no Notes of a principal amount of US$2,000 in original principal amount or less shall be redeemed in part and after any redemption, a Holder may only hold an authorized principal amount of Notes. In addition, if a partial redemption is made pursuant to the provisions described under “— Optional Redemption — Redemption with Proceeds from Equity Offerings,” selection of the Notes or portions thereof for redemption shall be made by the U.S. Trustee only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to the procedures of The Depository Trust Company (“DTC”)), unless that method is otherwise prohibited.

Notice of redemption will be delivered to the Holders at least 15, but not more than 60, days before the date of redemption, except that redemption notices may be delivered more than 60 days prior to a redemption date if

41

##### Table of Contents

the notice is issued in connection with a satisfaction and discharge of the Indenture. If any Note is to be redeemed in part only, the notice of redemption that relates to that Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon cancellation of the original Note. On and after the applicable date of redemption, interest will cease to accrue on Notes or portions thereof called for redemption so long as the Issuer has deposited with the Paying Agent for the Notes funds in satisfaction of the applicable redemption price (including accrued and unpaid interest on the Notes to be redeemed) pursuant to the Indenture.

Any redemption or notice may, at the Issuer’s discretion be subject to the satisfaction of one or more conditions precedent, including, without limitation, the occurrence of a Change of Control or the completion of a Qualified Equity Offering.

Change of Control

Upon the occurrence of any Change of Control, unless the Issuer has previously or concurrently exercised its right to redeem all of the Notes as described under “— Optional Redemption,” each Holder will have the right to require that the Issuer purchase all or any portion (equal to US$2,000 or an integral multiple of US$1,000 in excess thereof) of that Holder’s Notes for a cash price (the “Change of Control Purchase Price”) equal to 101.0% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of purchase.

Within 30 days following any Change of Control, the Issuer will deliver, or caused to be delivered, to the Holders, with a copy to the Trustee, a notice:

(1) describing the transaction or transactions that constitute the Change of Control;

(2) offering to purchase, pursuant to the procedures required by the Indenture and described in the notice (a “Change of Control Offer”), on a date specified in the notice, which shall be a Business Day not earlier than 30 days, nor later than 60 days, from the date the notice is delivered (the “Change of Control Payment Date”), and for the Change of Control Purchase Price, all Notes properly tendered by such Holder pursuant to such Change of Control Offer; and

(3) describing the procedures, as determined by the Issuer, consistent with the Indenture, that Holders must follow to accept the Change of Control Offer.

On the Business Day immediately preceding the Change of Control Payment Date, the Issuer will, to the extent lawful, deposit with the Paying Agent an amount equal to the Change of Control Purchase Price in respect of the Notes or portions of Notes properly tendered.

On the Change of Control Payment Date, the Issuer will, to the extent lawful:

(1) accept for payment all Notes or portions of Notes (of US$2,000 or integral multiples of US$1,000 in excess thereof) properly tendered pursuant to the Change of Control Offer; and

(2) deliver or cause to be delivered to the U.S. Trustee the Notes so accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer.

The Paying Agent will promptly deliver to each Holder who has so tendered Notes the Change of Control Purchase Price for such Notes, and the U.S. Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes so tendered, if any; provided that each such new Note will be in a principal amount of US$2,000 or integral multiples of US$1,000 in excess thereof.

42

##### Table of Contents

If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest, if any, will be paid on the relevant interest payment date to the Person in whose name a Note is registered at the close of business on such record date.

A Change of Control Offer will be required to remain open for at least 20 Business Days or for such longer period as is required by law. The Issuer will publicly announce the results of the Change of Control Offer on or as soon as practicable after the date of purchase.

In the event that Holders of not less than 90% of the aggregate principal amount of the outstanding Notes accept a Change of Control Offer and the Issuer purchases all of the Notes held by such Holders, the Issuer will have the right, upon not less than 30 days’ nor more than 60 days’ prior notice, which notice shall be delivered not more than 30 days following the purchase pursuant to the Change of Control Offer, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to the Change of Control Purchase Price plus, to the extent not included in the Change of Control Purchase Price, accrued and unpaid interest on the Notes to the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date).

If a Change of Control Offer is made, there can be no assurance that the Issuer will have available funds sufficient to pay for all or any of the Notes that might be delivered by Holders seeking to accept the Change of Control Offer. See “Risk Factors — Risks Related to the Notes — We may not have the ability to finance the change of control repurchase offer required by the indenture governing the notes.” In addition, in the event of a Change of Control the Issuer may not be able to obtain the consents necessary to consummate a Change of Control Offer from the lenders under agreements governing outstanding Indebtedness which may prohibit the offer. If we fail to repurchase all of the Notes tendered for purchase upon a Change of Control, such failure will constitute an Event of Default. In addition, the occurrence of certain of the events which would constitute a Change of Control may constitute an event of default under the Credit Agreement and the Existing Indentures and may constitute an event of default under future Indebtedness. Moreover, the exercise by the Holders of their right to require the Issuer to purchase the Notes could cause a default under such Indebtedness, even if the Change of Control itself does not, due to the financial effect of the repurchase on the Issuer. Finally, the Issuer’s ability to pay cash to the Holders upon a Change of Control may be limited by its then existing financial resources.

The provisions described above that require the Issuer to make a Change of Control Offer following a Change of Control will be applicable regardless of whether any other provisions of the Indenture are applicable to the transaction giving rise to the Change of Control. The Change of Control purchase feature of the Notes may in certain circumstances make more difficult or discourage a sale or takeover of us and, thus, the removal of incumbent management. The Change of Control purchase feature is a result of negotiations between the Issuer and the initial purchasers. The Issuer does not have the present intention to engage in a transaction involving a Change of Control, although it is possible that we could decide to do so in the future. Subject to the limitations discussed below, we could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a Change of Control under the Indenture, but that could increase the amount of Indebtedness outstanding at such time or otherwise affect our capital structure or credit ratings. Restrictions on our ability to incur additional Indebtedness are contained in the covenants described under “— Certain Covenants — Limitation on Additional Indebtedness” and “— Certain Covenants — Limitation on Liens.” Except as described above with respect to a Change of Control, the Indenture does not contain provisions that permit the Holders to require that the Issuer purchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction.

The Issuer’s obligation to make a Change of Control Offer will be satisfied if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Notes properly tendered and not withdrawn under such Change of Control Offer.

43

##### Table of Contents

With respect to any disposition of assets, the phrase “all or substantially all” as used in the Indenture (including as set forth under the definition of “Change of Control” and “— Certain Covenants — Limitation on Mergers, Consolidations, Etc.” below) varies according to the facts and circumstances of the subject transaction, has no clearly established meaning under New York law (which governs the Notes and the Indenture) and is subject to judicial interpretation. Accordingly, there may be a degree of uncertainty in ascertaining whether a particular transaction would involve a disposition of “all or substantially all” of the assets of the Issuer and the Restricted Subsidiaries, and therefore it may be unclear as to whether a Change of Control has occurred and whether the Holders have the right to require the Issuer to purchase Notes.

The Issuer will comply with all applicable securities legislation in Canada and the United States, including, without limitation, the requirements of Rule 14e-1 under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any applicable securities laws or regulations conflict with the “Change of Control” provisions of the Indenture, the Issuer shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the “Change of Control” provisions of the Indenture by virtue of such compliance.

The provisions under the Indenture relating to the Issuer’s obligation to make a Change of Control Offer may be waived, modified or terminated prior to the occurrence of the triggering Change of Control with the written consent of the Holders of a majority in principal amount of the Notes then outstanding.

Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

Certain Covenants

Covenant Termination

Following the first date that the Notes have a Moody’s rating of Baa3 or higher or an S&P rating of BBB- or higher and no Default or Event of Default has occurred and is then continuing, the Issuer and the Restricted Subsidiaries will no longer be subject to the following covenants:

(1) “— Certain Covenants — Limitation on Additional Indebtedness”;

(2) “— Certain Covenants — Limitation on Restricted Payments (except to the extent applicable under the definition of “Unrestricted Subsidiary”)”;

(3) “— Certain Covenants — Limitation on Dividend and Other Restrictions Affecting Restricted Subsidiaries”;

(4) “— Certain Covenants — Limitation on Transactions with Affiliates”;

(5) “— Certain Covenants — Limitation on Asset Sales”;

(6) clause (3) of the covenant described under “— Certain Covenants — Limitation on Mergers, Consolidations, Etc.”; and

(7) “ — Certain Covenants — Conduct of Business.”

Limitation on Additional Indebtedness

The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, incur any Indebtedness (including Acquired Indebtedness); provided that the Issuer or any Restricted Subsidiary may incur additional Indebtedness (including Acquired Indebtedness), in each case, if, after giving effect thereto on a pro forma basis, the Consolidated Interest Coverage Ratio would be at least 2.00 to 1.00 (the “Coverage Ratio Exception”).

44

##### Table of Contents

Notwithstanding the above, each of the following incurrences of Indebtedness shall be permitted (the “Permitted Indebtedness”):

(1) Indebtedness of the Issuer and any Restricted Subsidiary under the Credit Facilities in an aggregate principal amount at any time outstanding, including the issuance and creation of letters of credit and bankers’ acceptances thereunder (with letters of credit and bankers’ acceptances being deemed to have a principal amount equal to the face amount thereof) not to exceed the greater of (a) US$1,000.0 million and (b) 25.0% of the Issuer’s Consolidated Tangible Assets;

(2) Indebtedness under (a) the Notes and the Guarantees issued on the Issue Date and (b) the Exchange Notes and the Guarantees in respect thereof issued pursuant to the Registration Rights Agreement;

(3) Indebtedness of the Issuer and its Restricted Subsidiaries to the extent outstanding on the Issue Date, including without limitation, the Existing Notes and the guarantees thereof (other than Indebtedness referred to in clauses (1), (2), (4), (6), (7), (8), (9), (10), (12) and (16));

(4) (a) guarantees by the Issuer or Guarantors of Indebtedness permitted to be incurred in accordance with the provisions of the Indenture; provided that in the event such Indebtedness that is being guaranteed is Subordinated Indebtedness, then the related guarantee shall be subordinated in right of payment to the Notes or the Guarantees, as the case may be, and (b) guarantees of Indebtedness incurred by Restricted Subsidiaries that are not Guarantors in accordance with the provisions of the Indenture;

(5) Indebtedness under Hedging Obligations entered into for bona fide hedging purposes of the Issuer or any Restricted Subsidiary and not for the purpose of speculation; provided that in the case of Hedging Obligations relating to interest rates, (a) such Hedging Obligations relate to payment obligations on Indebtedness otherwise permitted to be incurred by this covenant, and (b) the notional principal amount of such Hedging Obligations at the time incurred does not exceed the principal amount of the Indebtedness to which such Hedging Obligations relate;

(6) Indebtedness of the Issuer owed to and held by a Restricted Subsidiary and Indebtedness of any Restricted Subsidiary owed to and held by the Issuer or any other Restricted Subsidiary; provided, however, that:

(a) if the Issuer is the obligor on Indebtedness and a Restricted Subsidiary that is not a Guarantor is the obligee, such Indebtedness is expressly subordinated to the prior payment in full in cash of all obligations with respect to the Notes;

(b) if a Guarantor is the obligor on such Indebtedness and a Restricted Subsidiary that is not a Guarantor is the obligee, such Indebtedness is subordinated in right of payment to the Guarantee of such Guarantor; and

(c)

provided, however, that at the time such Person or assets is/are acquired by the Issuer or a Restricted Subsidiary, or merged or consolidated with the Issuer of any Restricted Subsidiary and after giving pro forma effect to the incurrence of such Indebtedness pursuant to this clause (18) and any other related Indebtedness, either (i) the Issuer would have been able to incur US$1.00 of additional Indebtedness pursuant to the first paragraph of this covenant; or (ii) the Consolidated Interest Coverage Ratio of the Issuer

and its Restricted Subsidiaries would be greater than or equal to such Consolidated Interest Coverage Ratio immediately prior to such acquisition, merger or consolidation; and

(19) Indebtedness representing deferred compensation to directors, officers, members of management or employees (in their capacities as such) of the Issuer or any Restricted Subsidiary and incurred in the ordinary course of business.

For purposes of determining compliance with this covenant, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness described in clauses (1) through (19) above or is entitled to be incurred pursuant to the Coverage Ratio Exception, the Issuer shall, in its sole discretion, classify such item of Indebtedness and may divide and classify such Indebtedness in more than one of the types of Indebtedness described, except that Indebtedness incurred under the Credit Agreement on or prior to the Issue Date shall be deemed to have been incurred under clause (1) above, and may later reclassify any item of Indebtedness described in clauses (1) through (19) above (provided that at the time of reclassification it meets the criteria in such category or categories). In addition, for purposes of determining any particular amount of Indebtedness under this covenant, (i) guarantees, Liens or letter of credit obligations supporting Indebtedness otherwise included in the determination of such particular amount shall not be included so long as incurred by a Person that could have incurred such Indebtedness; and (ii) the amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with IFRS.

For the purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the U.S. dollar-equivalent principal amount of such Indebtedness incurred pursuant thereto shall be calculated based on the relevant currency exchange rate in effect on the earlier of the date that such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such Refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

In addition, the Issuer will not permit any of its Unrestricted Subsidiaries to incur any Indebtedness other than Non-Recourse Debt. If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary as of such date (and, if such Indebtedness is not permitted to be incurred as of such date under this “— Limitation on Additional Indebtedness” covenant, the Issuer shall be in Default of this covenant).

Limitation on Restricted Payments

The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, make any Restricted Payment if at the time of such Restricted Payment:

(1) a Default shall have occurred and be continuing or shall occur as a consequence thereof;

(2) the Issuer is not able to incur at least US$1.00 of additional Indebtedness pursuant to the Coverage Ratio Exception; or

(3) the amount of such Restricted Payment, when added to the aggregate amount of all other Restricted Payments made after the Issue Date (other than Restricted Payments made pursuant to clauses (2), (3), (4), (5), (6) or (10) of the next paragraph), exceeds the sum (the “Restricted Payments Basket”) of (without duplication):

(a) 50.0% of Consolidated Net Income of the Issuer and the Restricted Subsidiaries for the period (taken as one accounting period) commencing on October 1, 2010 to and including the last day of the fiscal quarter ended immediately prior to the date of such calculation for which consolidated financial statements are available (or, if such Consolidated Net Income shall be a deficit, minus 100.0% of such deficit),

plus

(b) 100.0% of (A) (i) the aggregate net cash proceeds and (ii) the Fair Market Value of (x) marketable securities (other than marketable securities of the Issuer), (y) Equity Interests of a Person (other than the Issuer or an Affiliate of the Issuer) engaged in a Permitted Business and (z) other assets used in any Permitted Business, received by the Issuer or its Restricted Subsidiaries after the Issue Date, in each case as a contribution to its common equity capital or from the issue or sale of Qualified Equity Interests or from the issue or sale of convertible or exchangeable Disqualified Equity Interests or convertible or exchangeable debt securities of the Issuer that have been converted into or exchanged for such Qualified Equity Interests (other than Equity Interests or debt securities sold to a Subsidiary of the Issuer or net cash proceeds received by the Issuer from Qualified Equity Offerings to the extent applied to redeem the Notes in accordance with the provisions set forth under “Optional Redemption — Redemption with Proceeds from Equity Offerings”), and (B) the aggregate net cash proceeds, if any, received by the Issuer or any of its Restricted Subsidiaries upon any conversion or exchange described in clause (A) above, plus

(c) 100.0% of the aggregate amount by which Indebtedness (other than any Subordinated Indebtedness or Indebtedness held by a Subsidiary of the Issuer) of the Issuer or any Restricted Subsidiary is reduced on the Issuer’s consolidated balance sheet upon the conversion or exchange after the Issue Date of any such Indebtedness into or for Qualified Equity Interests, plus

(d) in the case of the disposition or repayment of or return on any Investment that was treated as a Restricted Payment made by the Issuer or any Restricted Subsidiary after the Issue Date (other than the release of any guarantee), an amount (to the extent not included in the computation of Consolidated Net Income) equal to the lesser of (i) 100.0% of the aggregate amount received by the Issuer or any Restricted Subsidiary in cash or other property (valued at the Fair Market Value thereof) as the return of capital with respect to such Investment and (ii) the amount of such Investment that was treated as a Restricted Payment, in either case, less the cost of the disposition of such Investment and net of taxes, plus

(e) in the case of the release of any guarantee that was treated as a Restricted Payment made by the Issuer or any Restricted Subsidiary after the Issue Date, an amount equal to the amount of such guarantee that was treated as a Restricted Payment less any amount paid under such guarantee, plus

(f) upon a Redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary, an amount (to the extent not included in the computation of Consolidated Net Income) equal to the lesser of (i) the Fair Market Value of the Issuer’s proportionate interest in such Subsidiary immediately following such Redesignation, and (ii) the aggregate amount of the Issuer’s Investments in such Subsidiary to the extent such Investments reduced the Restricted Payments Basket and were not previously repaid or otherwise reduced.

(5) the redemption, repurchase or other acquisition or retirement for value of Equity Interests of the Issuer held by officers, directors or employees or former officers, directors or employees (or their transferees, estates or beneficiaries under their estates), either (x) upon any such individual’s death, disability, retirement, severance or termination of employment or service or (y) pursuant to any equity subscription agreement, stock option agreement, stockholders’ agreement or similar agreement; provided, in any case, that the aggregate cash consideration paid for all such redemptions, repurchases or other acquisitions or retirements shall not exceed (A) US$5.0 million during any calendar year (with unused amounts in any calendar year being carried forward to succeeding calendar years) plus (B) the amount of any net cash proceeds received by or contributed to the Issuer from the issuance and sale after the Issue Date of Qualified Equity Interests to its officers, directors or employees that have not been applied to the payment of Restricted Payments pursuant to this clause (5), plus (C) the net cash proceeds of any “key-man” life insurance policies that have not been applied to the payment of Restricted Payments pursuant to this clause (5); and provided, further, that cancellation of Indebtedness owing to the Issuer from members of management of the Issuer or any Restricted Subsidiary in connection with a repurchase of Equity Interests of the Issuer will not be deemed to constitute a Restricted Payment for purposes of this covenant or any other provision of the Indenture;

(6) (a) repurchases, redemptions or other acquisitions or retirements for value of Equity Interests of the Issuer deemed to occur upon the exercise of stock options, warrants, rights to acquire Equity Interests of the Issuer or other convertible securities to the extent such Equity Interests of the Issuer represent a portion of the exercise or exchange price thereof and (b) any repurchases, redemptions or other acquisitions or retirements for value of Equity Interests of the Issuer made in lieu of withholding taxes in connection with any exercise or exchange of stock options, warrants or other similar rights;

For the purposes of determining compliance with any U.S. dollar-denominated restriction on Restricted Payments denominated in a foreign currency, the U.S. dollar-equivalent amount of such Restricted Payment shall be calculated based on the relevant currency exchange rate in effect on the date that such Restricted Payment was made.

The Issuer will not permit any Unrestricted Subsidiary to become a Restricted Subsidiary except pursuant the covenant described under “— Limitation on Designations of Unrestricted Subsidiaries.” For purposes of designating any Restricted Subsidiary as an Unrestricted Subsidiary, all outstanding Investments by the Issuer and its Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated will be deemed to be Restricted Payments in an amount determined as set forth in the definition of “Investment.” Such designation will be permitted only if a Restricted Payment in such amount would be permitted at such time and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

For purposes of determining compliance with this covenant, in the event that a proposed Restricted Payment (or a portion thereof) meets the criteria of clauses (1) through (12) above or is entitled to be made pursuant to the Restricted Payments Basket or as a Permitted Investment, the Issuer will be entitled to divide, classify or later reclassify (based on circumstances existing on the date of such reclassification) such Restricted Payment (or portion thereof) among such clauses (1) through (12), the Restricted Payments Basket and any such Permitted Investments in a manner that otherwise complies with this covenant, and following such reclassification such Restricted Payment or Permitted Investment shall be treated as having been made pursuant to only the clause or clauses of this covenant to which such Restricted Payment or Permitted Investment has been reclassified.

Limitation on Dividend and Other Restrictions Affecting Restricted Subsidiaries

The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, create or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary to:

(a) pay dividends or make any other distributions on or in respect of its Equity Interests to the Issuer or any of its Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on Common Stock shall not be deemed a restriction on the ability to make distributions on Equity Interests);

Limitation on Transactions with Affiliates

The Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, in one transaction or a series of related transactions, sell, lease, transfer or otherwise dispose of any of its assets to, or purchase any assets from, or enter into any contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (an “Affiliate Transaction”) involving aggregate payments or consideration in excess of US$2.5 million, unless:

(1) the terms of such Affiliate Transaction are no less favorable in all material respects to the Issuer or such Restricted Subsidiary, as the case may be, than those that would have been obtained in a comparable transaction at the time of such transaction in arm’s length dealings with a Person who is not such an Affiliate; and

(2) the Issuer delivers to the Trustee, with respect to any Affiliate Transaction involving aggregate value in excess of US$25.0 million, an Officer’s Certificate certifying that such Affiliate Transaction complies with clause (1) above and a Secretary’s Certificate which sets forth and authenticates a resolution that has been adopted by the Independent Directors approving such Affiliate Transaction.

The foregoing restrictions shall not apply to:

Limitation on Liens

The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, incur, assume or permit or suffer to exist any Lien (other than Permitted Liens) upon any of their property or assets (including Equity Interests of any Restricted Subsidiary), whether owned at the Issue Date or thereafter acquired, which Lien secures Indebtedness or trade payables, unless contemporaneously with the incurrence of such Lien:

(1) in the case of any Lien securing an obligation that ranks pari passu with the Notes or a Guarantee, effective provision is made to secure the Notes or such Guarantee, as the case may be, at least equally and ratably with or prior to such obligation with a Lien on the same collateral; and

(2) in the case of any Lien securing an obligation that is subordinated in right of payment to the Notes or a Guarantee, effective provision is made to secure the Notes or such Guarantee, as the case may be, with a Lien on the same collateral that is senior to the Lien securing such subordinated obligation,

in each case, for so long as such obligation is secured by such Lien.

Limitation on Asset Sales

The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Sale unless:

(1) the Issuer or such Restricted Subsidiary, as the case may be, receives consideration at least equal to the Fair Market Value (such Fair Market Value to be determined on the date of contractually agreeing to such Asset Sale) of the shares and assets subject to such Asset Sale; and

(2) at least 75.0% of the total consideration from such Asset Sale received by the Issuer or such Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents.

For purposes of clause (2) above and for no other purpose, the following shall be deemed to be cash:

(a) the amount (without duplication) of any Indebtedness (other than Subordinated Indebtedness or intercompany Indebtedness) of the Issuer or such Restricted Subsidiary that is expressly assumed by the transferee of any such assets pursuant to a written novation agreement that releases the Issuer or such Restricted Subsidiary from further liability therefor,

(b) the amount of any securities, notes or other obligations received from such transferee that are within 180 days after such Asset Sale converted by the Issuer or such Restricted Subsidiary into cash (to the extent of the cash actually so received),

(c) any Designated Non-cash Consideration received by the Issuer or any of its Restricted Subsidiaries in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (c) that is at that time outstanding, not to exceed the greater of (i) US$100.0 million and (ii) 2.5% of the Issuer’s Consolidated Tangible Assets at the time of receipt of such Designated Non-cash Consideration, with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value, and

(d) the Fair Market Value of (i) any assets (other than securities) received by the Issuer or any Restricted Subsidiary to be used by it in a Permitted Business, (ii) Equity Interests in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the acquisition of such Person by the Issuer or (iii) a combination of (i) and (ii).

If at any time any non-cash consideration received by the Issuer or any Restricted Subsidiary, as the case may be, in connection with any Asset Sale is repaid or converted into or sold or otherwise disposed of for cash

53

##### Table of Contents

(other than interest received with respect to any such non-cash consideration), then the date of such repayment, conversion or disposition shall be deemed to constitute the date of an Asset Sale hereunder and the Net Available Proceeds thereof shall be applied in accordance with this covenant.

Any Asset Sale pursuant to a condemnation, expropriation, appropriation or other similar taking, including by deed in lieu of condemnation, or pursuant to the foreclosure or other enforcement of a Permitted Lien or exercise by the related lienholder of rights with respect thereto, including by deed or assignment in lieu of foreclosure shall not be required to satisfy the conditions set forth in clauses (1) and (2) of the first paragraph of this covenant.

Notwithstanding the foregoing, the 75.0% limitation referred to above shall be deemed satisfied with respect to any Asset Sale in which the cash or Cash Equivalents portion of the consideration received therefrom, determined in accordance with the foregoing provision on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75.0% limitation.

If the Issuer or any Restricted Subsidiary engages in an Asset Sale, the Issuer or such Restricted Subsidiary shall, no later than 365 days following the consummation thereof (or, if with respect to clause (3) below, within 365 days after the receipt of any Net Available Proceeds from any Asset Sale the Issuer or any Restricted Subsidiary entered into a contractual commitment, pursuant to a binding agreement, to apply any such Net Available Proceeds, then, within 545 days following the consummation thereof), apply all or any of the Net Available Proceeds therefrom to:

(1) permanently reduce (and permanently reduce commitments with respect thereto): (x) obligations under the Credit Agreement and/or (y) Indebtedness of the Issuer or a Restricted Subsidiary that is secured by a Lien (in each case other than any Disqualified Equity Interests or Subordinated Indebtedness, and other than Indebtedness owed to the Issuer or an Affiliate of the Issuer);

(2) permanently reduce obligations under other Indebtedness of the Issuer or a Restricted Subsidiary (in each case other than any Disqualified Equity Interests or Subordinated Indebtedness, and other than Indebtedness owed to the Issuer or an Affiliate of the Issuer); provided that the Issuer shall equally and ratably reduce obligations under the Notes as provided under “— Optional Redemption,” through open market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or by making an offer (in accordance with the procedures set forth below for a Net Proceeds Offer) to all Holders to purchase their Notes at 100% of the principal amount thereof, plus the amount of accrued but unpaid interest, if any, on the amount of Notes that would otherwise be prepaid; or

(3) (A) make any capital expenditure or otherwise invest all or any part of the Net Available Proceeds thereof in the purchase of assets (other than securities and excluding working capital or current assets for the avoidance of doubt) to be used by the Issuer or any Restricted Subsidiary in a Permitted Business, (B) acquire Qualified Equity Interests held by a Person other than the Issuer or any of its Restricted Subsidiaries in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the consummation of such acquisition or (C) a combination of (A) and (B).

The amount of Net Available Proceeds not applied or invested as provided in clauses (1) through (3) of the preceding paragraph will constitute “Excess Proceeds.”

When the aggregate amount of Excess Proceeds equals or exceeds US$50.0 million, the Issuer will be required to make an offer to purchase or redeem (a “Net Proceeds Offer”) from all Holders (unless the Issuer has previously or concurrently exercised its right to redeem all of the Notes as described under “— Optional Redemption”) and, to the extent required by the terms of other Pari Passu Indebtedness of the Issuer, to all holders of other Pari Passu Indebtedness outstanding with similar provisions requiring the Issuer to make an offer to purchase or redeem such Pari Passu Indebtedness with the proceeds from any Asset Sale, to purchase or redeem the maximum principal amount of Notes and any such Pari Passu Indebtedness to which the Net Proceeds

Offer applies that may be purchased or redeemed out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount of Notes and Pari Passu Indebtedness plus accrued and unpaid interest thereon, if any, to the date of purchase, in accordance with the procedures set forth in the Indenture or the agreements governing the Pari Passu Indebtedness, as applicable, in each case in denominations of US$2,000 or integral multiples of US$1,000 in excess thereof.

To the extent that the sum of the aggregate principal amount of Notes and Pari Passu Indebtedness so validly tendered pursuant to a Net Proceeds Offer is less than the Excess Proceeds, the Issuer may use any remaining Excess Proceeds, or a portion thereof, for any purposes not otherwise prohibited by the provisions of the Indenture. If the aggregate principal amount of Notes and Pari Passu Indebtedness so validly tendered pursuant to a Net Proceeds Offer exceeds the amount of Excess Proceeds, the Issuer shall select the Notes and Pari Passu Indebtedness to be purchased on a pro rata basis on the basis of the aggregate outstanding principal amount of Notes and Pari Passu Indebtedness. Upon completion of such Net Proceeds Offer in accordance with the foregoing provisions, the amount of Excess Proceeds with respect to which such Net Proceeds Offer was made shall be deemed to be zero.

The Net Proceeds Offer will remain open for a period of 20 Business Days following its commencement, except to the extent that a longer period is required by applicable law (the “Net Proceeds Offer Period”). No later than five Business Days after the termination of the Net Proceeds Offer Period (the “Net Proceeds Purchase Date”), the Issuer will purchase the principal amount of Notes and Pari Passu Indebtedness required to be purchased pursuant to this covenant (the “Net Proceeds Offer Amount”) or, if less than the Net Proceeds Offer Amount has been so validly tendered, all Notes and Pari Passu Indebtedness validly tendered in response to the Net Proceeds Offer.

If the Net Proceeds Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Net Proceeds Offer.

Pending the final application of any Net Available Proceeds pursuant to this covenant, the holder of such Net Available Proceeds may apply such Net Available Proceeds temporarily to reduce Indebtedness outstanding under a revolving Credit Facility or otherwise invest such Net Available Proceeds in any manner not prohibited by the Indenture.

On or before the Net Proceeds Purchase Date, the Issuer will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Net Proceeds Offer Amount of Notes and Pari Passu Indebtedness or portions of Notes and Pari Passu Indebtedness so validly tendered and not properly withdrawn pursuant to the Net Proceeds Offer, or if less than the Net Proceeds Offer Amount has been validly tendered and not properly withdrawn, all Notes and Pari Passu Indebtedness so validly tendered and not properly withdrawn, in each case in denominations of US$2,000 and integral multiples of US$1,000 in excess thereof. The Issuer will deliver to the Trustee an Officer’s Certificate stating that such Notes or portions thereof were accepted for payment by the Issuer in accordance with the terms of this covenant and, in addition, the Issuer will deliver all certificates and notes required, if any, by the agreements governing the Pari Passu Indebtedness. The Issuer or the Paying Agent, as the case may be, will promptly (but in any case not later than five Business Days after termination of the Net Proceeds Offer Period) mail or deliver to each tendering Holder and the Issuer will mail or deliver to each tendering holder or lender of Pari Passu Indebtedness, as the case may be, an amount equal to the purchase price of the Notes or Pari Passu Indebtedness so validly tendered and not properly withdrawn by such holder or lender, as the case may be, and accepted by the Issuer for purchase, and the Issuer will promptly issue a new Note, and the U.S. Trustee, upon delivery of an Officer’s Certificate from the Issuer, will authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered; provided that each such new Note will be in a principal amount of US$2,000 or an integral multiple of US$1,000 in excess thereof. In addition, the Issuer will take any and all other actions required by the agreements governing

55

##### Table of Contents

the Pari Passu Indebtedness. Any Note not so accepted will be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer will publicly announce the results of the Net Proceeds Offer on the Net Proceeds Purchase Date.

Notwithstanding the foregoing, the sale, conveyance or other disposition of all or substantially all of the assets of the Issuer and its Restricted Subsidiaries, taken as a whole, will be governed by the provisions of the Indenture described under the caption “— Change of Control” and/or the provisions described under the caption “— Limitation on Mergers, Consolidations, Etc.” and not by the provisions of the Asset Sale covenant.

The Issuer will comply with all applicable securities laws and regulations in Canada and the United States, including, without limitation, the requirements of Rule 14e-1 under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any applicable securities laws or regulations conflict with the “— Limitation on Asset Sales” provisions of the Indenture, the Issuer shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the “— Limitation on Asset Sales” provisions of the Indenture by virtue of such compliance.

The Credit Facilities may limit, and future credit agreements or other agreements relating to Indebtedness to which the Issuer (or one of its Affiliates) becomes a party may prohibit or limit, the Issuer from purchasing any Notes pursuant to this covenant. In the event the Issuer is contractually prohibited from purchasing the Notes, the Issuer could seek the consent of its lenders to the purchase of the Notes or could attempt to refinance the borrowings that contain such prohibition. If the Issuer does not obtain such consent or repay such borrowings, it will remain contractually prohibited from purchasing the Notes. In such case, the Issuer’s failure to purchase tendered Notes would constitute a Default under the Indenture.

Limitation on Designation of Unrestricted Subsidiaries

The Board of Directors of the Issuer may designate any Subsidiary (including any newly formed or newly acquired Subsidiary or a Person becoming a Subsidiary through merger or consolidation or Investment therein) of the Issuer as an “Unrestricted Subsidiary” under the Indenture (a “Designation”) only if:

(1) no Default shall have occurred and be continuing at the time of or after giving effect to such Designation; and

(2) the Issuer would be permitted to make, at the time of such Designation, (a) a Permitted Investment or (b) an Investment pursuant to the first paragraph of “— Limitation on Restricted Payments” above, in either case, in an amount (the “Designation Amount”) equal to the Fair Market Value of the Issuer’s proportionate interest in such Subsidiary on such date.

No Subsidiary shall be Designated as an “Unrestricted Subsidiary” unless:

(1) all of the Indebtedness of such Subsidiary and its Subsidiaries shall, at the date of Designation, consist of Non-Recourse Debt, except for any guarantee given solely to support the pledge by the Issuer or any Restricted Subsidiary of the Equity Interests of such Unrestricted Subsidiary, which guarantee is not recourse to the Issuer or any Restricted Subsidiary;

(2) on the date such Subsidiary is Designated an Unrestricted Subsidiary, such Subsidiary is not party to any agreement, contract, arrangement or understanding with the Issuer or any Restricted Subsidiary unless the terms of the agreement, contract, arrangement or understanding are no less favorable in any material respect to the Issuer or the Restricted Subsidiary than those that would be obtained at the time from Persons who are not Affiliates of the Issuer;

(3) such Subsidiary is a Person with respect to which neither the Issuer nor any of its Restricted Subsidiaries has any direct or indirect obligation (a) to subscribe for additional Equity Interests of such Person or (b) to maintain or preserve the Person’s financial condition or to cause the Person to achieve any specified levels of operating results; and

56

##### Table of Contents

(4) such Subsidiary has not guaranteed or otherwise directly or indirectly provided credit support for any Indebtedness of the Issuer or any Restricted Subsidiary, except for any guarantee given solely to support the pledge by the Issuer or any Restricted Subsidiary of the Equity Interests of such Unrestricted Subsidiary, which guarantee is not recourse to the Issuer or any Restricted Subsidiary.

Any such Designation by the Board of Directors of the Issuer shall be evidenced to the Trustee by filing with the Trustee a resolution of the Board of Directors of the Issuer giving effect to such Designation and an Officer’s Certificate certifying that such Designation complies with the foregoing conditions. If, at any time, any Unrestricted Subsidiary fails to meet the preceding requirements as an Unrestricted Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for purposes of the Indenture and any Indebtedness of the Subsidiary and any Liens on assets of such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary at such time and, if the Indebtedness is not permitted to be incurred under the covenant described under “— Limitation on Additional Indebtedness” or the Lien is not permitted under the covenant described under “— Limitation on Liens,” the Issuer shall be in default of the applicable covenant.

The Board of Directors of the Issuer may redesignate an Unrestricted Subsidiary as a Restricted Subsidiary (a “Redesignation”) only if:

(1) no Default shall have occurred and be continuing at the time of and after giving effect to such Redesignation; and

(2) all Liens, Indebtedness and Investments of such Unrestricted Subsidiary outstanding immediately following such Redesignation would, if incurred or made at such time, have been permitted to be incurred or made for all purposes of the Indenture.

Any such Redesignation shall be evidenced to the Trustee by filing with the Trustee a resolution of the Board of Directors of the Issuer giving effect to such designation and an Officer’s Certificate certifying that such Redesignation complies with the foregoing conditions.

Limitation on Mergers, Consolidations, Etc.

The Issuer will not, directly or indirectly, in a single transaction or a series of related transactions, consolidate, amalgamate or merge with or into or wind up or dissolve into another Person (whether or not the Issuer is the surviving Person), or sell, lease, transfer, convey or otherwise dispose of or assign all or substantially all of the assets of the Issuer and its Restricted Subsidiaries (taken as a whole) unless:

(1) either:

(a) the Issuer will be the surviving or continuing Person; or

(b) the Person (if other than the Issuer) formed by or surviving or continuing from such consolidation, merger, amalgamation, winding up or dissolution or to which such sale, lease, transfer, conveyance or other disposition or assignment shall be made (collectively, the “Successor”) is a corporation, limited liability company or limited partnership organized and existing under the laws of Canada or any province thereof or the United States of America or of any State of the United States of America or the District of Columbia, and the Successor expressly assumes, by agreements in form and substance reasonably satisfactory to the U.S. Trustee, all of the obligations of the Issuer under the Notes and the Indenture and expressly assumes all of the obligations of the Issuer under the Registration Rights Agreement; provided, that if the Successor is not a corporation, a Restricted Subsidiary that is a corporation expressly assumes as co-obligor all of the obligations of the Issuer under the Indenture and the Notes pursuant to a supplemental indenture to the Indenture executed and delivered to the Trustee;

(2) immediately after giving effect to such transaction and the assumption of the obligations as set forth in clause (1)(b) above and the incurrence of any Indebtedness to be incurred in connection therewith, and the use of any net proceeds therefrom on a pro forma basis, no Default shall have occurred and be continuing;

57

##### Table of Contents

(3) immediately after giving pro forma effect to such transaction and the assumption of the obligations as set forth in clause (1)(b) above and the incurrence of any Indebtedness to be incurred in connection therewith, and the use of any net proceeds therefrom on a pro forma basis, (i) the Issuer or its Successor, as the case may be, could incur US$1.00 of additional Indebtedness pursuant to the Coverage Ratio Exception or (ii) the Consolidated Interest Coverage Ratio for the Issuer or its Successor, as the case may be, and its Restricted Subsidiaries would be greater than or equal to such Consolidated Interest Coverage Ratio prior to such transaction; and

(4) the Issuer shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such merger, amalgamation, consolidation or transfer and such agreement and/or supplemental indenture (if any) comply with the Indenture.

For purposes of this covenant, any Indebtedness of the Successor which was not Indebtedness of the Issuer immediately prior to the transaction shall be deemed to have been incurred in connection with such transaction.

Subject to certain limitations governing releases of Guarantors described in the sixth paragraph under the caption “— Guarantees,” no Guarantor will, and the Issuer will not permit any Guarantor to, directly or indirectly, in a single transaction or a series of related transactions, consolidate, amalgamate or merge with or into or wind up or dissolve into another Person (whether or not the Guarantor is the surviving Person), or sell, lease, transfer, convey or otherwise dispose of or assign all or substantially all of its assets to any Person unless either:

(1) (a) (i) such Guarantor will be the surviving or continuing Person; or (ii) the Person (if other than such Guarantor) formed by or surviving any such consolidation, merger, amalgamation, winding-up or dissolution is another Guarantor or assumes, by agreements in form and substance reasonably satisfactory to the U.S. Trustee, all of the obligations of such Guarantor under the Guarantee of such Guarantor and the Indenture and assumes all of the obligations of such Guarantor under the Registration Rights Agreement;

(b) immediately after giving effect to such transaction, no Default shall have occurred and be continuing; and

(c) the Issuer shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such merger, amalgamation, consolidation or transfer and such agreements and/or supplemental indenture (if any) comply with the Indenture; or

(2) the transaction is made in compliance with the covenant described under “— Limitation on Asset Sales.”

For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Restricted Subsidiaries of the Issuer, the Equity Interests of which constitute all or substantially all of the properties and assets of the Issuer, will be deemed to be the transfer of all or substantially all of the properties and assets of the Issuer.

Upon any consolidation, amalgamation or merger of the Issuer or a Guarantor, or any transfer of all or substantially all of the assets of the Issuer in accordance with the foregoing, in which the Issuer or such Guarantor is not the continuing obligor under the Notes or its Guarantee, as applicable, the surviving entity formed by such consolidation or amalgamation or into which the Issuer or such Guarantor is merged or the Person to which the sale, conveyance, lease, transfer, disposition or assignment is made will succeed to, and be substituted for, and may exercise every right and power of, the Issuer or such Guarantor under the Indenture, the Notes and the Guarantees with the same effect as if such surviving entity had been named therein as the Issuer or such Guarantor and, except in the case of a lease, the Issuer or such Guarantor, as the case may be, will be released from the obligation to pay the principal of and interest on the Notes or in respect of its Guarantee, as the case may be, and all of the Issuer’s or such Guarantor’s other obligations and covenants under the Notes, the Indenture and its Guarantee, if applicable.

58

##### Table of Contents

Notwithstanding the foregoing, (i) any Restricted Subsidiary may consolidate, merge or amalgamate with or into or convey, transfer or lease, in one transaction or a series of transactions, all or substantially all of its assets to the Issuer or another Restricted Subsidiary and (ii) any Guarantor may consolidate, merge or amalgamate with or into or convey, transfer or lease, in one transaction or a series of transactions, all or part of its properties and assets to the Issuer or another Guarantor or merge with a Restricted Subsidiary of the Issuer solely for the purpose of reincorporating the Guarantor in Canada or a province thereof, a State of the United States or the District of Columbia, as long as the amount of Indebtedness of the Issuer or such Guarantor and its Restricted Subsidiaries is not increased thereby.

Additional Guarantees

If any Restricted Subsidiary of the Issuer shall guarantee any Indebtedness of the Issuer or any Guarantor under a Credit Facility or under debt securities issued in the capital markets (including the Existing Notes) except for any such Subsidiary if the Fair Market Value of the assets of such Subsidiary together with the Fair Market Value of the assets of any other Subsidiaries that guaranteed such Indebtedness of the Issuer or any Guarantor but did not guarantee the Notes, does not exceed US$20.0 million in the aggregate, then the Issuer shall cause such Restricted Subsidiary to:

(1) execute and deliver to the Trustee a supplemental indenture pursuant to which such Restricted Subsidiary shall unconditionally guarantee, on a joint and several basis, the full and prompt payment of the principal of, premium, if any, and interest (including Additional Interest, if any) in respect of the Notes on a senior basis and all other obligations of the Issuer under the Indenture; and

(2) deliver to the Trustee one or more Opinions of Counsel that such supplemental indenture (a) has been duly authorized, executed and delivered by such Restricted Subsidiary and (b) constitutes a valid and legally binding obligation of such Restricted Subsidiary in accordance with its terms.

Conduct of Business

The Issuer will engage, and will cause its Restricted Subsidiaries to engage, only in businesses that, when considered together as a single enterprise, are primarily the Permitted Business.

Reports

Whether or not required by the SEC, so long as any Notes are outstanding, the Issuer will furnish to the Trustee and the Holders of Notes, or, to the extent permitted by the SEC, file electronically with the SEC through the SEC’s Electronic Data Gathering, Analysis and Retrieval System (or any successor system) within the time periods specified in the SEC’s rules and regulations applicable to a foreign private issuer subject to the Multijurisdictional Disclosure System:

(1)

(a) all annual financial information that would be required to be contained in a filing with the SEC on Forms 40-F or 20-F (or any successor form), as applicable, containing the information required therein (or required in such successor form) including a report on the annual financial statements by the Issuer’s certified independent accountants as if the Issuer was required to file such forms and was a reporting issuer under the securities laws of the Province of Alberta or Ontario; and

(b) for the first three quarters of each year, all quarterly financial information that the Issuer would be required to file with or furnish to the SEC on Form 6-K (or any successor form), if the Issuer were required to file or furnish, as applicable, such forms and as if the Issuer was a reporting issuer under the securities laws of the Province of Alberta or Ontario,

in each case including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations”; and

59

##### Table of Contents

(2) all current reports that would otherwise be required to be filed or furnished by the Issuer with the SEC on Form 6-K if the Issuer were required to file or furnish, as applicable, such form as if the Issuer was a reporting issuer under the securities laws of the Province of Alberta or Ontario.

If the Issuer has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by the preceding paragraph will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Issuer and its Restricted Subsidiaries excluding the Unrestricted Subsidiaries.

In addition, whether or not required by the SEC, the Issuer will file a copy of all of the information and reports referred to in clauses (1) and (2) above with the SEC for public availability within the time periods specified in the SEC’s rules and regulations applicable to such reports applicable to a foreign private issuer subject to the Multijurisdictional Disclosure System (unless the SEC will not accept the filing) and make the information available to securities analysts and prospective investors upon request. If, notwithstanding the foregoing, the SEC will not accept the Issuer’s filings for any reason, the Issuer will post the reports referred to in clauses (1) and (2) above on its website within the time periods that would apply if the Issuer were required to file those reports with the SEC.

The Issuer and the Guarantors have agreed that, for so long as any Notes remain outstanding and “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act and not eligible to be resold pursuant to Rule 144(b)(1) of the Securities Act, the Issuer will furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act (for so long as such information is required in order to permit resales of the Notes pursuant to Rule 144A).

Notwithstanding anything to the contrary contained herein, the Issuer will be deemed to have complied with its obligations under this covenant following the filing of this registration statement and prior to the effectiveness hereof if this registration statement includes the information specified in clause (1) above at the times it would otherwise be required to file such Forms.

Events of Default

Each of the following is an “Event of Default”:

(1) failure to pay interest on, or Additional Interest with respect to, any of the Notes when the same becomes due and payable and the continuance of any such failure for 30 days;

(2) failure to pay principal of or premium, if any, on any of the Notes when it becomes due and payable, whether at Stated Maturity, upon redemption, upon purchase, upon acceleration or otherwise;

(3) failure by the Issuer or any of its Restricted Subsidiaries to comply with any of their respective agreements or covenants described above under “— Certain Covenants — Limitation on Mergers, Consolidations, Etc.,” or failure by the Issuer to comply in respect of its obligations to make a Change of Control Offer as described under “— Change of Control”;

(4) (a) except with respect to the covenant described under the heading “— Certain Covenants — Reports,” failure by the Issuer or any Restricted Subsidiary to comply with any other agreement or covenant in the Indenture and continuance of this failure for 60 days after notice of the failure has been given to the Issuer by the U.S. Trustee or to the Issuer and the Trustee by the Holders of at least 25.0% of the aggregate principal amount of the Notes then outstanding, or (b) failure by the Issuer for 120 days after notice of the failure has been given to the Issuer by the U.S. Trustee or by the Holders of at least 25.0% of the aggregate principal amount of the Notes then outstanding to comply with the covenant described under the heading “— Certain Covenants — Reports”;

60

##### Table of Contents

(5) default by the Issuer or any Significant Subsidiary under any mortgage, indenture or other instrument or agreement under which there may be issued or by which there may be secured or evidenced Indebtedness for borrowed money by the Issuer or any Restricted Subsidiary, whether such Indebtedness now exists or is incurred after the Issue Date, which default:

(a) is caused by a failure to pay at its Stated Maturity principal on such Indebtedness within the applicable express grace period and any extensions thereof, or

(b) results in the acceleration of such Indebtedness prior to its Stated Maturity (which acceleration is not rescinded, annulled or otherwise cured within 30 days of receipt by the Issuer or such Restricted Subsidiary of notice of any such acceleration),

and, in each case, the principal amount of such Indebtedness, together with the principal amount of any other Indebtedness with respect to which an event described in clause (a) or (b) has occurred and is continuing, aggregates US$50.0 million or more;

(6) one or more judgments (to the extent not covered by insurance) for the payment of money in an aggregate amount in excess of US$50.0 million shall be rendered against the Issuer, any of its Significant Subsidiaries or any combination thereof and the same shall remain undischarged for a period of 60 consecutive days during which execution shall not be effectively stayed;

(7) certain events of bankruptcy affecting the Issuer or any Significant Subsidiary of the Issuer or group of Restricted Subsidiaries of the Issuer that, taken together (as of the latest audited consolidated financial statements for the Issuer and its Restricted Subsidiaries), would constitute a Significant Subsidiary; or

(8) any Guarantee ceases to be in full force and effect (other than in accordance with the terms of such Guarantee and the Indenture) or is declared null and void and unenforceable or found to be invalid or any Guarantor denies its liability under the Guarantee of such Guarantor (other than by reason of release of such Guarantor from its Guarantee in accordance with the terms of the Indenture and the Guarantee).

If an Event of Default (other than an Event of Default specified in clause (7) above), shall have occurred and be continuing under the Indenture, the U.S. Trustee, by written notice to the Issuer, or the Holders of at least 25.0% in aggregate principal amount of the Notes then outstanding by written notice to the Issuer and the U.S. Trustee, may declare (an “acceleration declaration”) all amounts owing under the Notes to be due and payable. Upon such acceleration declaration, the aggregate principal of and accrued and unpaid interest on the outstanding Notes shall become due and payable immediately; provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of such outstanding Notes may, under certain circumstances, rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal and interest, have been cured or waived as provided in the Indenture. If an Event of Default specified in clause (7) occurs, all outstanding Notes shall become due and payable without any further action or notice to the extent permitted by applicable law.

Holders of the Notes may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any Default or Event of Default (except an Event of Default relating to the payment of principal or interest or Additional Interest) if it determines that withholding notice is in their interest.

61

##### Table of Contents

The Holders of a majority in principal amount of the then outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the U.S. Trustee. However, the U.S. Trustee may refuse to follow any direction that conflicts with law or the Indenture, that may involve the U.S. Trustee in personal liability, or that the U.S. Trustee determines in good faith may be unduly prejudicial to the rights of Holders of Notes not joining in the giving of such direction and may take any other action it deems proper that is not inconsistent with any such direction received from Holders of Notes. A Holder may not pursue any remedy with respect to the Indenture or the Notes unless:

(1) the Holder gives a Responsible Officer of the U.S. Trustee written notice of a continuing Event of Default;

(2) the Holder or Holders of at least 25.0% in aggregate principal amount of outstanding Notes make a written request to the U.S. Trustee to pursue the remedy;

(3) such Holder or Holders offer the U.S. Trustee indemnity satisfactory to the U.S. Trustee against any costs, liability or expense;

(4) the U.S. Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and

(5) during such 60-day period, the Holders of a majority in aggregate principal amount of the outstanding Notes do not give a Responsible Officer of the U.S. Trustee a direction that is inconsistent with the request.

However, such limitations do not apply to the right of any Holder of a Note to receive payment of the principal of, premium or Additional Interest, if any, or interest on, such Note or to bring suit for the enforcement of any such payment, on or after the due date expressed in the Notes, which right will not be impaired or affected without the consent of the Holder.

The Holders of a majority in aggregate principal amount of the Notes then outstanding by written notice to the U.S. Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest or premium or Additional Interest on, or the principal of, the Notes.

The Issuer is required to deliver to a Responsible Officer of the U.S. Trustee annually a statement regarding compliance with the Indenture and, upon any Officer of the Issuer becoming aware of any Default, a statement specifying such Default and what action the Issuer is taking or proposes to take with respect thereto. The Issuer will also be obligated to notify a Responsible Officer of the U.S. Trustee of any default or defaults in the performance of any covenants or agreements under the Indenture.

Legal Defeasance and Covenant Defeasance

The Issuer may, at its option and at any time, elect to have its obligations discharged with respect to the outstanding Notes and all obligations of any Guarantors discharged with respect to their Guarantees (“Legal Defeasance”). Legal Defeasance means that the Issuer and the Guarantors shall be deemed to have paid and discharged the entire obligations represented by the Notes and the Guarantees, and the Indenture shall cease to be of further effect as to all outstanding Notes and Guarantees, except as to:

(1) rights of Holders of outstanding Notes to receive payments in respect of the principal of and interest and Additional Interest, if any, on such Notes when such payments are due from the funds referred to below;

(2) the Issuer’s obligations with respect to the Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes, and the maintenance of an office or agency for payment and money for security payments held in trust;

(3) the rights, powers, trust, duties, and immunities of the Trustee, and the obligations of the Issuer and the Guarantors in connection therewith; and

(4) the Legal Defeasance provisions of the Indenture.

62

##### Table of Contents

In addition, the Issuer may, at its option and at any time, elect to have its obligations and the obligations of the Guarantors released with respect to the provisions of the Indenture described above under “— Change of Control” and under “— Covenants” (other than the covenant described under “— Covenants — Limitation on Mergers, Consolidations, Etc.,” except to the extent described below) and the limitation imposed by clause (3) under “— Covenants — Limitation on Mergers, Consolidations, Etc.” (such release and termination being referred to as “Covenant Defeasance”), and thereafter any omission to comply with such obligations or provisions will not constitute a Default or Event of Default. Covenant Defeasance will not be effective until the date 92 days after the date of deposit of funds provided for in clause (1) of the paragraph below, and then only if no bankruptcy, receivership, rehabilitation and insolvency event has occurred and is continuing. In the event Covenant Defeasance occurs in accordance with the Indenture, the Events of Default described under clauses (3) through (8) under the caption “— Events of Default” will no longer constitute an Event of Default. The Issuer may exercise its Legal Defeasance option regardless of whether it previously exercised Covenant Defeasance.

In order to exercise either Legal Defeasance or Covenant Defeasance:

(1) the Issuer must irrevocably deposit with the U.S. Trustee in trust solely for the benefit of the Holders, U.S. legal tender, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest) in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants selected by the Issuer delivered to the Trustee, to pay the principal of and interest and Additional Interest, if any, on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be,

(2) in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the U.S. Trustee confirming that:

(a) the Issuer has received from, or there has been published by the Internal Revenue Service, a ruling, or

(b) since the date of the Indenture, there has been a change in the applicable U.S. federal income tax law,

in either case to the effect that, and based thereon this Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred,

(3) in the case of Covenant Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the U.S. Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the Covenant Defeasance had not occurred,

(4) in the case of Legal Defeasance or Covenant Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the U.S. Trustee and qualified to practice in Canada or a ruling from Canada Revenue Agency to the effect that Holders of the outstanding Notes who are not resident in Canada should not recognize income, gain or loss for Canadian federal, provincial or territorial income tax purposes as a result of the Legal Defeasance or Covenant Defeasance, as applicable, and should be subject to Canadian federal, provincial or territorial income tax on the same amounts, in the same manner and at the same times as would have been the case if the Legal Defeasance or Covenant Defeasance, as applicable, had not occurred,

(5) no Default shall have occurred and be continuing, either (a) on the date of such deposit (other than a Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings) or (b) insofar as Defaults from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit,

(6) the Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under any other material agreement or instrument to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound,

(7) the Issuer has delivered to the Trustee an Opinion of Counsel to the effect that after the 91st day following the deposit, no trust funds will be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally,

(8) the Issuer shall have delivered to the Trustee an Officer’s Certificate stating that the deposit was not made by it with the intent of preferring the Holders over any other of its creditors or with the intent of defeating, hindering, delaying or defrauding any other of its creditors or others, and

(9) the Issuer shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that the conditions precedent provided for in clauses (1) through (8) have been complied with.

If the funds deposited with the U.S. Trustee to effect Covenant Defeasance are insufficient to pay the principal of and interest on the Notes when due, then the Issuer’s obligations and the obligations of the Guarantors under the Indenture will be revived and no such defeasance will be deemed to have occurred.

Satisfaction and Discharge

The Indenture will be discharged and will cease to be of further effect (except as to rights of registration of transfer or exchange of Notes which shall survive until all Notes have been canceled and the rights, protections and immunities of the Trustee) as to all outstanding Notes when either:

(1) all the Notes that have been authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from this trust) have been delivered to the Trustee for cancellation, or

(2) (a) all Notes not delivered to the Trustee for cancellation otherwise (i) have become due and payable, (ii) will become due and payable, or may be called for redemption, within one year or (iii) have been called for redemption pursuant to the provisions described under “— Optional Redemption,” and, in any case, the Issuer has irrevocably deposited or caused to be deposited with the Trustee as trust funds, in trust solely for the benefit of the Holders, U.S. legal tender, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest) to pay and discharge the entire Indebtedness (including all principal and accrued interest and Additional Interest, if any) on the Notes not theretofore delivered to the Trustee for cancellation,

(b) the Issuer has paid all other sums payable by it under the Indenture, and

(c) the Issuer has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or on the date of redemption, as the case may be.

In addition, the Issuer must deliver an Officer’s Certificate and an Opinion of Counsel stating that all conditions precedent to satisfaction and discharge of the Indenture have been complied with.

Transfer and Exchange

A Holder is able to register the transfer of or exchange Notes only in accordance with the provisions of the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. Without the prior consent of the Issuer, the Registrar is not required (1) to register the transfer of or exchange any Note selected for redemption, (2) to register the transfer of or exchange any Note for a period of 15 days before a selection of Notes to be redeemed or (3) to register the transfer or exchange of a Note between a record date and the next succeeding interest payment date.

64

##### Table of Contents

The Notes are issued in registered form and the registered Holder will be treated as the owner of such Note for all purposes (except as required by applicable tax laws).

Amendment, Supplement and Waiver

Except as otherwise provided in the next three succeeding paragraphs, the Indenture, the Guarantees or the Notes may be amended with the consent (which may include consents obtained in connection with a tender offer or exchange offer for Notes) of the Holders of at least a majority in principal amount of the Notes then outstanding, and any existing Default under, or compliance with any provision of, the Indenture may be waived (other than any continuing Default in the payment of the principal or interest on the Notes) with the consent (which may include consents obtained in connection with a tender offer or exchange offer for Notes) of the Holders of a majority in principal amount of the Notes then outstanding.

Without the consent of each Holder affected, an amendment or waiver may not (with respect to any Notes held by a non-consenting Holder):

(1) reduce, or change the maturity of, the principal of any Note;

(2) reduce the rate of or extend the time for payment of interest on any Note;

(3) reduce any premium payable upon redemption of the Notes or change the date on which any Notes are subject to redemption (other than the notice provisions) or waive any payment with respect to the redemption of the Notes; provided, however, that solely for the avoidance of doubt, and without any other implication, any purchase or repurchase of Notes (including pursuant to the covenants described above under the captions “— Change of Control” and “— Certain Covenants — Limitation on Asset Sales”) shall not be deemed a redemption of the Notes;

(4) make any Note payable in money or currency other than that stated in the Notes;

(5) modify or change any provision of the Indenture or the related definitions to affect the ranking of the Notes or any Guarantee in a manner that adversely affects the Holders;

(6) reduce the percentage of Holders necessary to consent to an amendment or waiver to the Indenture or the Notes;

(7) waive a default in the payment of principal of or premium or interest or Additional Interest, if any, on any Notes (except a rescission of acceleration of the Notes by the Holders thereof as provided in the Indenture and a waiver of the payment default that resulted from such acceleration);

(8) impair the rights of Holders to receive payments of principal of or interest or Additional Interest, if any, on the Notes on or after the due date therefor or to institute suit for the enforcement of any payment on the Notes;

(9) release any Guarantor from any of its obligations under its Guarantee or the Indenture, except as permitted by the Indenture; or

(10) make any change in these amendment and waiver provisions.

Notwithstanding the foregoing, the Issuer and the Trustee may amend the Indenture, the Guarantees or the Notes without the consent of any Holder:

(1) to cure any ambiguity, defect or inconsistency;

(2) to provide for uncertificated Notes in addition to or in place of certificated Notes;

(3) to provide for the assumption of the Issuer’s or a Guarantor’s obligations to the Holders in the case of a merger, amalgamation, consolidation or sale of all or substantially all of the Issuer’s or such Guarantor’s assets, or winding-up or dissolution or sale, lease, transfer, conveyance or other disposition or assignment in accordance with “— Certain Covenants — Limitation on Mergers, Consolidations, Etc.”;

65

##### Table of Contents

(4) to add any Guarantee or to effect the release of any Guarantor from any of its obligations under its Guarantee or the provisions of the Indenture (to the extent in accordance with the Indenture);

(5) to make any change that would provide any additional rights or benefits to the Holders or does not materially adversely affect the rights of any Holder;

(6) to effect or maintain the qualification of the Indenture under the Trust Indenture Act;

(7) to secure the Notes or any Guarantees or any other obligation under the Indenture;

(8) to evidence and provide for the acceptance of appointment by a successor Trustee;

(9) to conform the text of the Indenture or the Notes to any provision of this Description of the Notes to the extent that such provision in this Description of the Notes was intended to be a substantially verbatim recitation of a provision of the Indenture, the Guarantees or the Notes; or

(10) to provide for the issuance of Additional Notes or Exchange Notes in accordance with the Indenture and the Registration Rights Agreement, as the case may be.

The consent of the Holders of the Notes is not necessary under the Indenture to approve the particular form of any proposed amendment or waiver. It is sufficient if such consent approves the substance of the proposed amendment or waiver.

After an amendment under the Indenture becomes effective, the Issuer is required to deliver to Holders of the Notes a notice briefly describing such amendment. However, the failure to give such notice to all Holders of the Notes, or any defect therein, will not impair or affect the validity of the amendment.

No Personal Liability of Directors, Officers, Employees and Stockholders

No director, officer, employee, incorporator, or stockholder of the Issuer or any Guarantor or an annuitant under a plan of which a stockholder of the Issuer is a trustee or carrier will have any liability for any indebtedness, obligations or liabilities of the Issuer under the Notes or the Indenture or of any Guarantor under its Guarantee or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes and the Guarantees. The waiver may not be effective to waive liabilities under the federal securities laws. It is the view of the SEC that this type of waiver is against public policy.

Concerning the Trustee

The U.S. Trustee has been appointed by the Issuer as Registrar and Paying Agent with regard to the Notes. The Indenture contains certain limitations on the rights of the Trustee, should it become a creditor of the Issuer, to obtain payment of claims in certain cases, or to realize on certain assets received in respect of any such claim as security or otherwise. The Trustee is permitted to engage in other transactions; however, if it acquires any conflicting interest (as defined in the Indenture), it must eliminate such conflict within 90 days, apply to the SEC for permission to continue (if the Indenture has been qualified under the Trust Indenture Act) or resign.

The Holders of a majority in principal amount of the then outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee, subject to certain exceptions. The Indenture provides that, in case an Event of Default occurs and is not cured, the Trustee will be required, in the exercise of its power, to use the degree of care of a prudent person in similar circumstances in the conduct of his own affairs. The Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request of any Holder, unless such Holder shall have offered to the Trustee security and indemnity satisfactory to the Trustee.

Governing Law

The Indenture, the Notes, and the Guarantees are governed by, and construed in accordance with, the laws of the State of New York.

Enforceability of Judgments

Since a substantial portion of the Issuer’s assets and the assets of many of the Guarantors are outside the United States, any judgment obtained in the United States against the Issuer or any non-U.S. domiciled Guarantor in respect of its Guarantee, including judgments with respect to the payment of principal, or interest on the Notes may not be collectible within the United States.

The Issuer has been informed by its Alberta counsel, Norton Rose Fulbright Canada LLP, that the laws of the Province of Alberta permit an action to be brought against the Issuer or a Guarantor over which it has jurisdiction in a court of competent jurisdiction in such province in accordance with its normal procedural rules on any final and conclusive civil judgment in personam of any federal or state court located in the Borough of Manhattan in The City of New York (“New York Court”) for a sum certain with respect to the Indenture, the Notes or a Guarantee, that has not been stayed or satisfied, is not under appeal or appealable, is not impeachable as void or voidable under the internal laws of the State of New York and in respect of which there is no other subsisting judgment in any other jurisdiction relating to the same cause of action if (1) the New York Court rendering such judgment has jurisdiction over the judgment debtor and the subject matter of the action under the laws of New York and the Province of Alberta (and submission by the Issuer or a Guarantor in the Indenture or in a supplemental indenture to the non-exclusive jurisdiction of the New York Court will be sufficient for the latter purpose); (2) such judgment was not obtained by fraud or in a manner contrary to natural justice and the enforcement thereof would not be inconsistent with public policy, as such term is understood under the laws of the Province of Alberta and the laws of Canada applicable therein, for example because that would be contrary to any order made by the Attorney General of Canada under the Foreign Extraterritorial Measures Act (Canada) or the Competition Tribunal under the Competition Act (Canada), or the enforcement of such judgment would constitute, directly or indirectly, the enforcement of foreign revenue, expropriatory, penal or other public laws; (3) the New York Court did not assume jurisdiction or render judgment as a result of a fraud practice on such court; (4) there is no new evidence that the judgment was obtained by fraud as to the merits of the claim which was not discoverable with due diligence before the judgment was granted; (5) there is no manifest error on the face of the judgment; (6) no new admissible evidence, right or defense relevant to the action accrues or is discovered prior to the rendering of judgment by a court of the Province of Alberta; and (7) the action to enforce such judgment is commenced within the applicable limitation period under the law of the Province of Alberta or the federal laws of Canada applicable therein for avoiding enforcement of such judgments of New York Courts under the Indenture, the Notes or a Guarantee based upon public policy. An Action in the Province of Alberta to enforce such judgment of the New York Court may be affected by Canadian laws relating to bankruptcy, insolvency or the enforcement of creditors’ rights generally and to general principles of equity including the availability of defenses such as laches, waiver or estoppel. If the judgment of the New York Court includes an interest component, such interest component to the date of the judgment of the New York Court would be included in the principal amount of the applicable court judgment in respect thereof, with interest accruing on the amount of the New York Court judgment to the date of the applicable court judgment at the applicable pre-judgment interest rate under the laws of the Province of Alberta and from the date of such applicable court judgment at the applicable post-judgment interest rate under the laws of the Province of Alberta. Further, any order of a court in the Province of Alberta will only be payable in Canadian dollars and the exchange rate used by such court may be different than that specified in the Indenture, the Notes or a Guarantee, as applicable.

Indemnification for Judgment Currency Fluctuations

If for the purposes of obtaining judgment in any court it is necessary to convert a sum due under the Indenture to the Holder from U.S. dollars to another currency, the Issuer has agreed, and each Holder by holding such Note will be deemed to have agreed, to the fullest extent that the Issuer and they may effectively do so, that

67

##### Table of Contents

the rate of exchange used shall be that at which in accordance with normal banking procedures such Holder could purchase U.S. dollars with such other currency in New York City, New York on the Business Day preceding the day on which final judgment is given.

The Issuer’s obligations to any Holder will, notwithstanding any judgment in a currency (the “judgment currency”) other than U.S. dollars, be discharged only to the extent that on the Business Day following receipt by such Holder or the Trustee, as the case may be, of any amount in such judgment currency, such Holder or Trustee may in accordance with normal banking procedures purchase U.S. dollars with the judgment currency. If the amount of the U.S. dollars so purchased is less than the amount originally to be paid to such Holder or the Trustee in the judgment currency (as determined in the manner set forth in the preceding paragraph), as the case may be, each of the Issuer and the Guarantors, jointly and severally, agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Holder and the Trustee, as the case may be, against any such loss. If the amount of the U.S. dollars so purchased is more than the amount originally to be paid to such Holder or the Trustee, as the case may be, such Holder or the Trustee, as the case may be, will pay the Issuer such excess; provided that such Holder or the Trustee, as the case may be, shall not have any obligation to pay any such excess as long as a Default under the Notes or the Indenture has occurred and is continuing or if the Issuer shall have failed to pay any Holder any amounts then due and payable under such Note or the Indenture, in which case such excess may be applied by such Holder to such obligations.

Consent to Jurisdiction and Service

Each of the Issuer and each non-U.S. Guarantor has appointed CT Corporation System, 111 Eighth Avenue, New York, New York, 10011 as its agent for service of process in any suit, action or proceeding with respect to the Indenture, the Notes or the Guarantees and for actions brought under federal or state securities laws brought in any federal or state court located in The City of New York and each of the Issuer and the Guarantors have submitted to the non-exclusive jurisdiction of such courts.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following discussion pertains to the material United States federal income tax consequences of the exchange of Outstanding Notes for Exchange Notes pursuant to the exchange offer, and the ownership and disposition of Exchange Notes acquired pursuant to the exchange offer, but does not purport to be a complete analysis of all the potential tax considerations. Except where noted, this discussion deals only with U.S. holders (as defined below) that acquired the Outstanding Notes at their initial public offering price, that acquire Exchange Notes pursuant to the exchange offer, and that held the Exchange Notes and will hold the Outstanding Notes as capital assets for U.S. federal income tax purposes (generally, property held for investment).

A “U.S. holder” means a beneficial owner of the notes that is: (1) an individual who is a citizen or resident of the United States as determined for United States federal income tax purposes, (2) a corporation (or any other entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (3) an estate the income of which is subject to United States federal income taxation regardless of its source, or (4) a trust if it (A) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust or (B) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person.

This discussion is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), and Treasury regulations, rulings and judicial decisions as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in United States federal income tax consequences different from those summarized below. This discussion does not address all aspects of United States federal income taxes that may be relevant to U.S. holders in light of their personal circumstances. In addition, it does not represent a detailed description of the United States federal income tax consequences applicable to you if you are subject to special treatment under the United States federal income tax laws. For example, this discussion does not address: (1) tax consequences to holders that may be subject to special tax treatment, such as dealers in securities or currencies, traders in securities that elect to use the mark-to-market method of accounting for their securities, financial institutions, regulated investment companies, real estate investment trusts, partnerships or other pass-through entities for United States federal income tax purposes, tax-exempt entities or insurance companies, (2) tax consequences to persons holding the notes as part of a hedging, integrated, constructive sale or conversion transaction or a straddle, (3) tax consequences to holders of the notes whose “functional currency” is not the United States dollar, (4) alternative minimum tax consequences, if any, or (5) any United States federal estate and gift tax consequences or any state, local or foreign tax consequences.

If a partnership or other pass-through entity holds the Exchange Notes, the tax treatment of a partner in or owner of the partnership or pass-through entity will generally depend upon the status of the partner or owner and the activities of the entity. If you are a partner in or owner of a partnership or other pass-through entity that is considering holding Exchange Notes, you are urged to consult your own tax advisors.

If you are considering the exchange of Outstanding Notes for Exchange Notes, you are urged to consult your own tax advisors concerning the particular United States federal income tax consequences to you of the exchange and the ownership and disposition of the Exchange Notes, as well as the consequences to you arising under the laws of any other taxing jurisdiction.

Exchange Offer

The exchange of an Outstanding Note for an Exchange Note in the exchange offer will not be treated as a taxable event to U.S. holders for United States federal income tax purposes. Consequently, you will not recognize gain or loss upon receipt of an Exchange Note, the holding period of the Exchange Note will include the holding period of the Outstanding Note exchanged therefor and the basis of the Exchange Note will be the same as the basis of the Outstanding Note immediately before the exchange.

89

##### Table of Contents

Payments of Stated Interest

Stated interest on an Exchange Note will generally be taxable to you as ordinary income at the time it is paid or accrued in accordance with your method of accounting for United States federal income tax purposes. In addition to interest on the Exchange Notes (which includes any foreign tax withheld from the interest payments you receive), you will be required to include in income any Additional Amounts (as described under “Description of the Notes — Payment of Additional Amounts”) paid in respect of such foreign tax withheld. You may be entitled to deduct or credit this tax, subject to certain limitations (including that the election to deduct or credit foreign taxes applies to all of your foreign taxes for a particular tax year). Interest income (including any Additional Amounts) on an Exchange Note generally will be considered foreign source income and, for purposes of the United States foreign tax credit, generally will be considered passive category income. You will generally be denied a foreign tax credit for foreign taxes imposed with respect to the Exchange Notes where you do not meet a minimum holding period requirement during which you are not protected from risk of loss. The rules governing the foreign tax credit are complex. You are urged to consult your own tax advisors regarding the availability of the foreign tax credit under your particular circumstances.

Sale, Exchange or Retirement of Notes

Your adjusted tax basis in a note will, in general, be your cost for that Exchange Note. Upon the sale, exchange, retirement or other taxable disposition of an Exchange Note, you will recognize gain or loss equal to the difference between the amount you realize upon the sale, exchange, retirement or other disposition (less an amount equal to any accrued but unpaid stated interest, which will be taxable as interest income to the extent not previously included in income) and your adjusted tax basis in the Exchange Note. Such gain or loss will be capital gain or loss and will generally be treated as United States source gain or loss. Capital gains of non-corporate holders, including individuals, derived in respect of capital assets held for more than one year are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations.

Backup Withholding and Information Reporting

Generally, information reporting requirements will apply to all payments we make to you, and the proceeds from a sale of an Exchange Note paid to you, unless you are an exempt recipient. Additionally, if you fail to provide your taxpayer identification number, or in the case of interest payments, fail either to report in full dividend and interest income or to make certain certifications, you may be subject to backup withholding.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against your United States federal income tax liability provided that the required information is timely furnished to the Internal Revenue Service.

Certain U.S. holders that are individuals may be required to report information relating to an interest in Exchange Notes subject to certain exceptions (including an exception for notes held in accounts maintained by domestic financial institutions). You are urged to consult your own tax advisors regarding your reporting requirements.

Additional Tax on Passive Income

Certain U.S. holders that are individuals, estates or trusts will be required to pay a 3.8 percent tax on, among other things, interest income and capital gains from the sale or other disposition of Exchange Notes.

The following is, as of the date hereof, a general summary of the principal Canadian federal income tax considerations generally applicable to a Non-Canadian Holder (as defined below) who acquires, as beneficial owner, Exchange Notes issued in exchange for Outstanding Notes pursuant to this exchange offer. This summary is based on the current provisions of the Income Tax Act (Canada) and the regulations thereunder (collectively, the “Tax Act”), relevant jurisprudence, and our understanding of the current administrative policies and assessing practices of the Canada Revenue Agency (the “CRA”) published in writing and publicly available, all as in effect as of the date hereof. Except for specifically proposed amendments to the Tax Act that have been publicly announced by or on behalf of the Canadian Minister of Finance prior to the date hereof, this summary does not otherwise take into account or anticipate proposed or possible changes in law, whether by judicial or legislative action, or changes in the administrative policies and assessing practices of the CRA nor does it consider the income tax legislation of any province, territory or foreign jurisdiction. This summary is not exhaustive of all possible Canadian federal income tax considerations and is of a general nature only and is not intended to be, and should not be construed to be, legal or tax advice to any particular Non-Canadian Holder. The tax considerations applicable to a Non-Canadian will depend on such Non-Canadian Holder’s personal circumstances. Accordingly, prospective Non-Canadian Holders are urged to consult their own tax advisors regarding the income tax consequences associated with the exchange of Outstanding Notes for Exchange notes pursuant to this exchange offer, having regard to their own particular circumstances.

This summary is only applicable to a holder of Outstanding Notes who, at all relevant times, for the purposes of the Tax Act and any relevant income tax treaty or convention is not resident in Canada and is not deemed to be resident in Canada and who, at all relevant times for the purposes of the Tax Act: (i) does not use or hold, and is not deemed to use or hold, Outstanding Notes or Exchange Notes in, or in the course of, carrying on a trade or business in Canada; (ii) is not an insurer who carries on an insurance business, or is deemed to carry on an insurance business, in Canada or elsewhere; (iii) deals at arm’s length with us, the guarantors, and with any transferee who is resident in Canada for the purposes of the Tax Act and to whom the holder assigns or otherwise transfers an Exchange Note; (iv) is not affiliated with us or the guarantors; (v) holds the Outstanding Notes and Exchange Notes as capital property; and (vi) is not a “specified non-resident shareholder” of us or a guarantor, or a person that does not deal at arm’s length for purposes of the Tax Act with a “specified shareholder” of us or a guarantor, in each case, for purposes of subsection 18(5) of the Tax Act (each such holder is referred to herein as a “Non-Canadian Holder”). Generally, Outstanding Notes and Exchange Notes will be capital property to a Non-Canadian Holder, provided such holder does not acquire or hold such notes in the course of carrying on a business of trading or dealing in securities or as part of an adventure in the nature of trade. No representation or warranty is made as to the tax consequences to a Canadian resident of acquiring Exchange Notes in exchange for Outstanding Notes. Canadian residents are advised that acquiring Exchange Notes in exchange for Outstanding Notes may give rise to particular tax consequences affecting them and are strongly encouraged to consult with their tax advisors.

This summary assumes that no interest paid on the Exchange Notes will be in respect of a debt or other obligation to pay an amount to a person with whom we or a guarantor does not deal at arm’s length within the meaning of the Tax Act.

CERTAIN ERISA CONSIDERATIONS

The following is a summary of certain considerations associated with the holding of Exchange Notes by employee benefit plans that are subject to Title I of the U.S. Employee Retirement Income Security Act of 1974, as amended (“ERISA”), plans, individual retirement accounts and other arrangements that are subject to Section 4975 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), or provisions under any other federal, state, local, non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Code (collectively, “Similar Laws”), and entities whose underlying assets are considered to include “plan assets” of any such employee benefit plan, plan, account or arrangement (each, a “Plan”).

General Fiduciary Matters

ERISA and the Code impose certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA or Section 4975 of the Code (an “ERISA Plan”) and prohibit certain transactions involving the assets of an ERISA Plan and its fiduciaries or other interested parties. Under ERISA and the Code, any person who exercises any discretionary authority or control over the administration of such an ERISA Plan or the management or disposition of the assets of such an ERISA Plan, or who renders investment advice for a fee or other compensation to such an ERISA Plan, is generally considered to be a fiduciary of the ERISA Plan.

In considering an investment in the Exchange Notes of a portion of the assets of any Plan, a fiduciary should determine whether the investment is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code or any Similar Law relating to a fiduciary’s duties to the Plan including, without limitation, the prudence, diversification and prohibited transaction provisions of ERISA, the Code and any other applicable Similar Laws.

Prohibited Transaction Issues

Section 406 of ERISA and Section 4975 of the Code prohibit ERISA Plans from engaging in specified transactions involving plan assets with persons or entities who are “parties in interest,” within the meaning of ERISA, or “disqualified persons,” within the meaning of Section 4975 of the Code, unless an exemption is applicable to the transaction. A party in interest or disqualified person who engaged in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code. In addition, the fiduciary of the ERISA Plan that engaged in such a non-exempt prohibited transaction may be subject to penalties and liabilities under ERISA and the Code. The acquisition and/or holding of an interest in the Exchange Notes by an ERISA Plan with respect to which we are considered a party in interest or a disqualified person may constitute or result in a direct or indirect prohibited transaction under Section 406 of ERISA and/or Section 4975 of the Code, unless the investment is acquired and is held in accordance with an applicable statutory, class or individual administrative prohibited transaction exemption. In this regard, the U.S. Department of Labor has issued prohibited transaction class exemptions, or “PTCEs,” that may apply to the acquisition and holding of an interest in the notes (or the Exchange Notes). These class exemptions include, without limitation, PTCE 84-14 respecting transactions determined by independent qualified professional asset managers, PTCE 90-1 respecting insurance company pooled separate accounts, PTCE 91-38 respecting bank collective investment funds, PTCE 95-60 respecting life insurance company general accounts and PTCE 96-23 respecting transactions determined by in-house asset managers. In addition, Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code provide limited relief from the prohibited transaction provisions of ERISA and Section 4975 of the Code for certain transactions between an ERISA Plan and certain “service provider” parties in interest or disqualified persons with respect to the Plan, provided that neither the service provider nor any of its affiliates (directly or indirectly) have or exercise any discretionary authority or control or render any investment advice with respect to the assets of the ERISA Plan involved in the transaction and provided further that the ERISA Plan pays no more than, and receives no less than, adequate consideration in connection with the transaction. There can be no assurance that all of the conditions of any of the foregoing exemptions, or any other exemption, will be satisfied with respect to any transaction involving an interest in the Exchange Notes.

##### Table of Contents

Plans such as non U.S. plans, governmental plans and certain church plans not subject to the fiduciary responsibility and prohibited transaction provisions of ERISA or the Code may nevertheless be subject to Similar Laws. Before purchasing any interest in the Exchange Notes, fiduciaries of such Plans should confirm that such purchase and holding will satisfy applicable Similar Laws and determine the need for, and the availability of, if necessary, any exemptive relief under any applicable Similar Laws.

Because of the foregoing, no interest in the Exchange Notes should be acquired or held by any person investing “plan assets” of any Plan, unless the exchange of Outstanding Notes for Exchange Notes) and holding will not constitute a non-exempt prohibited transaction under ERISA and the Code or a similar violation of any applicable Similar Laws.

Representation

Accordingly, by exchanging an Outstanding Note for an Exchange Note, each purchaser and subsequent transferee will be deemed to have represented and warranted that either (i) no portion of the assets used by such purchaser or transferee to acquire or hold the Exchange Notes constitutes assets of any Plan or (ii) the acquisition and holding of the Exchange Notes by such purchaser or transferee will not constitute a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a similar violation under any applicable Similar Laws.

The foregoing discussion is general in nature and is not intended to be all inclusive. Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries, or other persons considering exchanging Outstanding Notes for Exchange Notes) on behalf of, or with the assets of, any Plan, consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code and any Similar Laws to such investment and whether an exemption would be applicable to the purchase and holding of an interest in the Exchange Notes.

Any such resale may be made directly to purchasers or through brokers or dealers who may receive compensation in the form of commissions or concessions from any broker-dealer and/or the purchasers of any Exchange Notes. Any broker-dealer that resells Exchange Notes that were received by it for its own account pursuant to the exchange offer and any broker or dealer that participates in a distribution of the Exchange Notes may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit of any resale of Exchange Notes and any commissions or concessions received by these persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

For a period of 180 days after the expiration date, we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the letter of transmittal.

Grey Wolf International Drilling Corporation is incorporated under the Canada Business Corporations Act.

Pursuant to the provisions of the Canada Business Corporations Act (the “CBCA”), a CBCA corporation may indemnify a current or former director or officer or any other individual who, at the request of the corporation, acts or has acted as a director or officer, or in any similar capacity, of the corporation or any other entity. Such indemnity may include all costs, charges and expenses reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual becomes involved as a result of having acted as a director or officer, or in any similar capacity, of the corporation or such other entity.

the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, the individual had reasonable grounds for believing that their conduct was lawful. Current and former directors and officers, and those acting in a similar capacity, will be entitled to indemnification from a CBCA corporation if they have not been judged by a court or other competent authority to have committed any fault or omitted to do anything they ought to have done and conditions (a) and (b) set out above in this paragraph have been fulfilled. A CBCA corporation may advance moneys to an indemnified individual for the costs, charges and expenses of a proceeding; however, such individual must repay the moneys if they do not satisfy conditions (a) and (b) set out above in this paragraph. CBCA corporations may purchase and maintain liability insurance for the benefit for those individuals entitled to indemnification under the CBCA. In the case of a derivative action, indemnification may only be made with court approval.

Except as otherwise required by the CBCA and provided for in the bylaws, the corporation may from time to time indemnify and save harmless any person who was or is a party or is threatened to be made a party to any threatened, pending or contemplated action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he is or was an employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee, agent of or participant in another body corporate, partnership, joint venture, trust or other enterprise, against expenses (including legal fees), judgments, fines and any amount actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted honestly and in good faith with a view to the best interests of the corporation and, with respect to any criminal or administrative action or proceeding that is enforced by a monetary penalty, had reasonable grounds for believing that his conduct was lawful. The termination of any action, suit or proceeding by judgment, order, settlement or conviction shall not, of itself, create a presumption that the person did not act honestly and in good faith with a view to the best interests of the corporation and, with respect to any criminal or administrative action or proceeding that is enforced by a monetary penalty, had no reasonable grounds for believing that his conduct was lawful. The provisions for indemnification contained in the bylaws of the corporation shall not be deemed exclusive of any other rights to which any person seeking indemnification may be entitled under any agreement, vote of shareholders or directors or otherwise, both as to action in his official capacity and as to action in another capacity, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs and legal representatives of such a person.

The certificate of incorporation of each of Murco Drilling Corporation, Precision Completion & Production Services Ltd. and Precision Drilling, Inc. indemnifies and advances expenses to all current and former officers of the corporation to the fullest extent permitted by applicable laws, as such laws exist and to such greater extent as they may provide in the future and provides that the liability of the directors of the corporation to the corporation or its stockholders for monetary damages shall be limited to the fullest extent permitted by applicable laws, as such laws exist and to such greater extent as they may provide in the future. Each of the bylaws of Murco Drilling Corporation, Precision Completion & Production Services Ltd. and Precision Drilling, Inc. further state that each person who was or is a party or is threatened to be made a party to or is involved in any threatened, pending or completed action, by reason of the fact that he is or was a director or officer of the corporation or is or was serving at the request of the corporation in any other shall be indemnified and held harmless by the corporation to the fullest extent permitted by law and with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful; provided, however, that the corporation shall indemnify any such person seeking indemnification in connection with a proceeding initiated by such person only if such proceeding was authorized by the Board of Directors of the corporation. With respect to actions by or in the right of the corporation, each of the bylaws provide that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been finally adjudged to be liable for negligence or misconduct in the performance of his duty to the corporation unless and only to the extent that the court in which such action is brought or any other court of competent jurisdiction, shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses as such court shall deem proper.

Nevada Registrant

Precision Drilling Holdings Company is incorporated under the laws of Nevada.

Section 78.138(7) of Chapter 78 of the Nevada Revised Statutes (“NRS”), which Chapter is entitled “Private Corporations” (“Nevada Corporation Law”), provides that with certain specified statutory exceptions or unless the articles of incorporation provide for greater individual liability, a director or officer of a Nevada corporation is not individually liable to the corporation or its stockholders or creditors for any damages as a result of any act or failure to act in his or her capacity as a director or officer unless it is proven that: (a) the director’s or officer’s act or failure to act constituted a breach of his or her fiduciary duties as a director or officer; and (b) the breach of those duties involved intentional misconduct, fraud or a knowing violation of law.

Under NRS 78.7502(1) a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative (except an action by or in the right of the corporation), by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving, at the request of the corporation, as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, or other enterprise, against expenses, including attorneys’ fees, judgments, fines, and amounts paid in settlement, actually and reasonably incurred by the person in connection with the action, suit, or proceeding, if the person (a) is not liable pursuant to NRS 78.138(7) or (b) acted in good faith and in a manner which he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the conduct was unlawful.

Under NRS 78.7502(2) a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation or another entity at the request of the corporation, including amounts paid in settlement and attorneys’ fees actually and reasonably incurred by the person in the defense or settlement of the action or suit if the person (a) is not liable pursuant to NRS 78.138(7) or (b) acted in good faith and in a manner which he or she reasonably believed to be in, or not opposed to, the best interests of the corporation. However, indemnification may not be made for any claim, issue or matter as to which the person seeking indemnification has been adjudged by a court of competent jurisdiction, after all exhaustion of appeals therefrom, to be liable to the corporation or for amounts paid in settlement to the corporation unless the court in which the action or suit was brought or other court of competent jurisdiction determines that in view of all of the circumstances, the person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper.

Under NRS 78.7502(3) a corporation shall indemnify a director, officer, employee or agent to the extent he or she has been successful on the merits or otherwise in defense of any action, suit, or proceeding referred to in NRS 78.7502(1) or (2), against expenses, including attorneys’ fees, actually and reasonably incurred by him or her in connection with the defense.

Under NRS 78.751(1) any discretionary indemnification pursuant to NRS 78.7502, unless ordered by a court or advanced by a corporation upon the receipt of an undertaking by or on behalf of the indemnified party in accordance with NRS 78.751(2), may be made by the corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances. The determination must be made (a) by the stockholders; (b) by the board of directors by a majority vote of a quorum consisting of directors who were not parties to the action, suit or proceeding; (c) if a majority vote of a quorum consisting of directors who were not parties to the action, suit or proceeding so orders, by independent legal counsel in a written opinion; or (d) if a quorum consisting of directors who were not parties to the action, suit or proceeding cannot be obtained, by independent legal counsel in a written opinion.

Under NRS 78.751(2) the articles of incorporation, the bylaws or an agreement made by the corporation may provide that the corporation will advance expenses incurred by directors or officers in defending a civil or

criminal action, suit, or proceeding as they are incurred and in advance of the final disposition of the action, suit, or proceeding, upon receipt of an undertaking that is provided by or on behalf of such directors or officers to repay such advances if it is ultimately determined by a court of competent jurisdiction that they are not entitled to indemnification by the corporation.

Pursuant to NRS 78.751(3), a right to indemnification or to advancement of expenses arising under a provision of the articles of incorporation or any bylaw is not eliminated or impaired by an amendment to such provision after the occurrence of the act or omission that is the subject of the civil, criminal, administrative or investigative action, suit or proceeding for which indemnification or advancement of expenses is sought, unless the provision in effect at the time of such act or omission explicitly authorizes such elimination or impairment after such action or omission has occurred.

The Articles of Incorporation of Precision Drilling Holdings Company provide that it shall, to the fullest extent permitted by the Nevada Corporation Law, as the same may be amended or supplemented, indemnify any and all persons whom it shall have power to indemnify under Nevada Corporation Law from and against any and all of the expenses, liabilities or other matters referred to in or covered by Nevada Corporation Law, and that such indemnification shall not be deemed exclusive of any other rights to which those indemnified may be entitled under Precision Drilling Holding Company’s Articles of Incorporation or under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to actions in his or her official capacity and as to actions in another capacity while holding such office and said indemnification shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such person. The Bylaws of Precision Drillings Holding Corporation contain similar provisions for indemnification of the directors and officers of the corporation.

Texas Registrants

DI Energy, Inc., DI/Perfensa Inc., Grey Wolf International, Inc., PD Supply Inc., Precision Drilling (US) Corporation and Precision Directional Services, Inc. are corporations incorporated under the laws of Texas. Precision Drilling Company, LP is a limited partnership formed under the laws of Texas.

Pursuant to Chapter 8 of the Texas Business Organizations Code (the “TBOC”), controlling persons, directors or officers of the registrants formed under the laws of Texas may be insured or indemnified against liability which may be incurred in their capacities as such. The following paragraphs describe the general effect of certain provisions of Chapter 8 of the TBOC and are qualified in their entirety by reference to Chapter 8 of the Texas Business Organizations Code.

Under Section 8.101 of TBOC, a corporation or limited partnership (an “enterprise”), and a predecessor to any such enterprise may indemnify a person serving as part of the governing authority (including the board of directors, general partners, managers, members) of the enterprise (a “governing person”), a former governing person, or a person who, while serving as a governing person of the enterprise, is or was serving at the enterprise’s request as a representative of another enterprise, organization, or employee benefits plan (a “delegate”) who was, is, or is threatened to be made a named defendant or respondent in a proceeding against judgment and reasonable expenses (including court costs, penalties, settlements, fines, excise and similar taxes, and reasonable attorney’s fees) actually incurred by the person in connection with the proceeding if it is determined that (a) the person seeking indemnification acted in good faith, reasonably believed that his or her conduct was in (or, if not acting in the person’s official capacity, at least not opposed to) the best interests of the enterprise and, in the case of a criminal proceeding, has no reasonable cause to believe his or her conduct was unlawful, (b) expenses (other than a judgment) are reasonable, and (c) indemnification should be paid, except that if the person is found liable to the enterprise or improperly received a personal benefit, the enterprise may indemnify such person only for reasonable expenses (including court costs, settlements, and reasonable attorney’s fees, but excluding judgments, penalties, fines, excise and similar taxes) actually incurred by the person in connection with the proceeding. Section 8.102 of the TBOC prohibits an enterprise from indemnifying

F-4 - II-6

##### Table of Contents

any such person in respect of any such proceeding in which the person is found liable (as established by a non-appealable court order) for willful or intentional misconduct in the performance of the person’s duties to the enterprise, breach of the person’s duty of loyalty owed to the enterprise, or an act or omission not in good faith that constitutes a breach of a duty owed by such person to the enterprise. Under Section 8.105 of the TBOC, an enterprise may indemnify and advance expenses to an officer, employee, agent, or other person that is not a governing person as provided by (i) the enterprise’s governing documents, (ii) action of the enterprise’s board of directors or other governing authority, (iii) resolution of the enterprise’s owners or members, (iv) contract, or (v) common law. A person who is not a governing person also may seek indemnification or advancement of expenses to the same extent that a governing person may seek indemnification or advancement under Chapter 8 of the TBOC. Section 8.105 of the TBOC also provides that an enterprise may pay or reimburse, in advance of the final disposition of a proceeding and on terms the enterprise considers appropriate, reasonable expenses incurred by a former governing person or delegate, or present or former employee, agent, officer or other person that is not a governing person, who was or is threatened to be made a named defendant or respondent in the proceeding.

An enterprise is required by Sections 8.051 and 8.105 of the TBOC to indemnify a governing person, former governing person, delegate, or officer against reasonable expenses (including court costs, judgments, penalties, settlements, fines, excise and similar taxes, and reasonable attorney’s fees) actually incurred by the person in connection with a proceeding in which the person is a named defendant or respondent due to the fact that the person is or was in that position if the person has been wholly successful, on the merits or otherwise, in the defense of the proceeding. Under Section 8.052 of the TBOC, on application and after notice is provided, a court may order an enterprise to indemnify a governing person, former governing person, or delegate to the extent the court determines that the person is fairly and reasonably entitled to indemnification in view of all the relevant circumstances, without regard to whether the governing person, former governing person, or delegate applying to the court satisfies the requirements of Section 8.101 of the TBOC or has been found liable to the enterprise or for improperly receiving a personal benefit whether or not resulting from action taken in such person’s official capacity; however, if the person is found liable to the enterprise or is found liable on the basis that a personal benefit was improperly received by the person, the indemnification will be limited to reasonable expenses (including court costs, judgments, penalties, settlements, fines, excise and similar taxes, and reasonable attorney’s fees).

Under Section 8.151 of the TBOC, an enterprise may maintain insurance or another arrangement to indemnify or hold harmless an existing or former governing person, delegate, officer, employee, or agent against liability asserted against or incurred by the person in that capacity or arising out of the person’s status in that capacity, without regard to whether the enterprise otherwise would have had the power to indemnify the person against that liability under Chapter 8 of the TBOC, subject to certain conditions. Additionally, an enterprise may also take certain other steps for the benefit of the persons to be indemnified such as creating a trust fund, establishing self-insurance, granting a security interest in the enterprise’s assets to secure the indemnity obligation, or establishing a letter of credit, guaranty, or surety arrangement.

Under Section 8.104 of the TBOC, an enterprise may pay or reimburse reasonable expenses (including court costs, judgments, penalties, settlements, fines, excise and similar taxes, and reasonable attorney’s fees) incurred by a present governing person or delegate who was, is, or is threatened to be made a named defendant or respondent in a proceeding in advance of the final disposition of the proceeding upon the enterprise’s receipt of a written affirmation by the person of the person’s good faith belief that the person has met the standard of conduct necessary for indemnification and a written undertaking by or on behalf of the person to repay the amount paid or reimbursed if the final determination is that the person has not met that standard or that indemnification is prohibited under Section 8.102 of the TBOC. Subject to Section 8.003 of the TBOC and to the extent consistent with law, Section 8.105 of the TBOC provides that an enterprise may advance expenses to an officer, employee, agent, or other person that is not a governing person as provided by (i) the enterprise’s governing documents, (ii) action of the enterprise’s board of directors or other governing authority, (iii) resolution of the enterprise’s owners, (iv) contract, or (v) common law.

Under Section 8.106 of the TBOC, an enterprise may pay or reimburse reasonable expenses incurred by a governing person, officer, employee, agent, delegate, or other person in connection with that person’s appearance as a witness or other participant in a proceeding at a time when the person is not a named defendant or respondent in the proceeding.

Under Section 8.003 of the TBOC, the circumstances in which an enterprise may or is required to indemnify, or may advance expenses to, a person under the TBOC may be restricted by the enterprise’s certificate of formation or partnership agreement.

The certificates, bylaws, articles and agreement of limited partnership of the registrants formed under the laws of Texas include certain provisions under which controlling persons, directors, or officers of such entities may be insured or indemnified against liability which may be incurred in their capacity as such, the general effect of which is described below.

Each of the certificates of formation of PD Supply Inc. and of Precision Drilling (US) Corporation provides that no director of the corporation shall be personally liable to the corporation or its shareholders for monetary damages for an act or omission in the director’s capacity as a director, except to the extent otherwise expressly provided by a statute of the State of Texas. All directors of the corporation shall be entitled to indemnification by the corporation to the maximum extent permitted by the TBOC (or such comparable statutory provision governing indemnification by a Texas corporation of its directors as may from time to time be applicable). If the TBOC or the Texas Miscellaneous Corporation Laws Act hereafter is amended to authorize the further elimination or limitation of the liability of directors, then the liability of a director of the corporation, in addition to the limitation on personal liability provided herein, shall be eliminated or limited to the fullest extent permitted by the amended statute.

The bylaws of PD Supply Inc. and of Precision Drilling (US) Corporation provide that each person who at any time shall serve, or shall have served, as a director, officer, employee or agent of the corporation, or any person who, while a director, officer, employee or agent of the corporation, is or was serving at the request of the corporation as a director, officer, partner, venturer, proprietor, trustee, employee, agent, member, manager or similar functionary of another foreign or domestic corporation, partnership, limited partnership, joint venture, sole proprietorship, trust, limited liability company, employee benefit plan or other enterprise (each such person referred to herein as an “indemnitee”), shall be entitled to indemnification as and to the fullest extent permitted by Chapter 8 of the TBOC or any successor statutory provision, as from time to time amended. The foregoing right of indemnification shall not be deemed exclusive of any other rights to which those to be indemnified may be entitled as a matter of law or under any agreement, other provision of such bylaws, vote of shareholders or directors, or other arrangement. The corporation may enter into indemnification agreements with its executive officers and directors that contractually provide to them the benefits of the indemnification provisions of Article 8 of such bylaws and include related provisions meant to facilitate the indemnitees’ receipt of such benefits and such other indemnification protections as may be deemed appropriate. The foregoing rights of an indemnitee shall include, but not be limited to, the right to be indemnified and to have expenses advanced in all proceedings to the fullest extent permitted by Chapter 8 of the TBOC or any successor statutory provisions, as from time to time amended. In the event that an indemnitee is not wholly successful, on the merits or otherwise, in a proceeding but is successful, on the merits or otherwise, as to any claim in such proceeding, the corporation shall indemnify the indemnitee against all expenses actually and reasonably incurred by the indemnitee or on the indemnitee’s behalf relating to each claim. To the extent an indemnitee is, by reason of his corporate status, a witness or otherwise participates in the proceeding at a time when the indemnitee is not a named defendant or respondent in the proceeding, he or she shall be indemnified against all expenses actually and reasonably incurred by the indemnitee or on the indemnitee’s behalf in connection with the proceeding. The bylaws further provide that if a person seeks a judicial adjudication to enforce the indemnitee’s rights under or to recover damages for breach of rights created pursuant to Article 8 of the bylaws, the indemnitee shall be entitled to recover from and be indemnified by the corporation against any and all expenses actually and reasonably incurred by the indemnitee in such judicial adjudication but only if the indemnitee prevails. The corporation also

may purchase and maintain insurance on behalf of a person who is or was a director, officer, employee, or agent of the corporation or who is or was serving at the request of the corporation as a director, officer, partner, venture, proprietor, trustee, employee, agent, or similar function of another enterprise against any liability asserted against or incurred by the person in that capacity or arising out of his or her status as such a person, regardless of whether the corporation would have the power to indemnify the person against that liability under the TBOC or Article 8 of the bylaws.

The bylaws of DI Energy, Inc. and Grey Wolf International, Inc. provide that the corporation shall indemnify every director or officer or former director or officer of the corporation or any person who may have served at its request as a director or officer of the corporation or any person who may have served at its request as a director or officer (or in a similar capacity) of another corporation, partnership, joint venture, trust, other enterprise or employee benefit plan, against reasonable expenses (including attorneys’ fees), damages, fines, penalties, judgments, amounts paid in settlement, and other liabilities actually and reasonably incurred by him in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, to which he may be made a party or in which he may become involved by reason of his being or having been such a director or officer (whether or not involving action in his official capacity as director or officer), except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable for gross negligence, recklessness or willful misconduct in the performance of his duty to the corporation, unless and only to the extent that a court of appropriate jurisdiction shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity. Any indemnification (unless ordered by a court of appropriate jurisdiction) shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of the director or officer is proper in the circumstances because he is not guilty of gross negligence, recklessness or willful misconduct in the performance of his duty to the corporation. In the event such a determination is made under the bylaws that the director or officer has met the applicable standard of conduct as to some matters but not as to others, amounts to be indemnified may be reasonably prorated. Expenses incurred in appearing at, participating in or defending any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative or investigative, shall be paid by the corporation at reasonable intervals in advance of the final disposition of such action, suit or proceeding after a determination is made in the manner specified in the bylaws that the information then known to those making the determination does not establish that indemnification would not be permissible under such bylaws and upon receipt by the corporation of a written affirmation by the director or officer of his good faith belief that he has met the standard of conduct necessary for indemnification by the corporation and a written undertaking by or on behalf of the director or officer to repay such amount unless it shall ultimately be determined that he is entitled to be indemnified by the corporation. The bylaws further provide that it is the intent of the corporation to indemnify persons referenced therein to the fullest extent permitted by law, and that the indemnification provided in such bylaws shall not be deemed exclusive of any other rights to which those seeking indemnification may be entitled and shall continue after a person has ceased to be a director or officer and shall inure to the benefit of the heirs, executors, and administrators of such person.

The articles of incorporation of DI/Perfensa Inc. provide that a director of the corporation shall not be personally liable to the corporation or its shareholders for monetary damages for any act or omission in his capacity as a director, except to the extent otherwise expressly provided by a statute of the State of Texas.

The bylaws of DI/Perfensa Inc. provide that the corporation shall indemnify every present or former director, advisory director, or officer of the corporation, any person who while serving in any such capacity served at the corporation’s request as a director, officer, partner, venturer, proprietor, trustee, employee, agent, or similar functionary of another foreign or domestic corporation, partnership, joint venture, trust, employee benefit plan, or other enterprise, and any person nominated or designated by the board of directors or any committee of the board to serve in such capacities (each an “indemnitee”), against all judgments, penalties (including excise and similar taxes), fines, amounts paid in settlement and reasonable expenses (including court costs and attorneys’ fees and disbursements) actually incurred by the indemnitee in connection with any proceeding in

which he was, is or is threatened to be named a defendant or respondent, or in which he was or is a witness without being named a defendant or respondent, by reason, in whole or in part, of his serving or having served, or having been nominated or designated to serve, in any of the capacities referred to, if it is determined that the indemnitee conducted himself in good faith, reasonably believed, in the case of conduct in his official capacity, that his conduct was in the corporation’s best interests and, in all other cases, that his conduct was at least not opposed to the corporation’s best interest, and in the case of any criminal proceeding, had no reasonable cause to believe that his conduct was unlawful; provided, however, that in the event that an indemnitee is found liable to the corporation or is found liable on the basis that personal benefit was improperly received by the indemnitee the indemnification is limited to reasonable expenses actually incurred by the indemnitee in connection with the proceeding and shall not be made in respect of any proceeding in which the indemnitee shall have been found liable for willful or intentional misconduct in the performance of his duty to the corporation. Except as provided above, no indemnification shall be made in respect of any proceeding in which such indemnitee shall have been found liable on the basis that personal benefit was improperly received by him, whether or not the benefit resulted from an action taken in the indemnitee’s official capacity, or found liable to the corporation. The indemnification provided in such bylaws shall be applicable whether or not negligence or gross negligence of the indemnitee is alleged or proven. The corporation shall indemnify every indemnitee against reasonable expenses incurred by such person in connection with any proceeding in which he is a witness or a named defendant or respondent because he served in any of the capacities referred to, if such person has been wholly successful, on the merits or otherwise, in defense of the proceeding. Reasonable expenses (including court costs and attorney’s fees) incurred by an indemnitee who was or is a witness or was, is, or is threatened to be made a named defendant or respondent in a proceeding shall be paid by the corporation at reasonable intervals in advance of the final disposition of such proceeding and without making the determination of proper indemnification specified in the bylaws, after receipt by the corporation of a written affirmation by the indemnitee of his good faith belief that he has met the standard of conduct necessary for indemnification by the corporation under the bylaws and a written undertaking by or on behalf of the indemnitee to repay the amount paid or reimbursed by the corporation if it is ultimately determined that he is not entitled to be indemnified by the corporation. The bylaws further provide that the corporation may pay or reimburse expenses incurred by an indemnitee in connection with his appearance as a witness or other participant in a proceeding at a time when he is not a named defendant or respondent in the proceeding. The bylaws further provide that such indemnification shall not be deemed exclusive of, or preclude, any other rights to which those seeking indemnification may at any time be entitled and shall continue as to a person who has ceased to be in the capacity by reason of which he was an indemnitee with respect to matters arising during the period he was in such capacity, and inure to the benefit of the heirs, executors, and administrators of such person.

The certificate of formation and bylaws of Precision Directional Services, Inc. provide that each person who at any time is or was a director or officer of the company, and who was, is or is threatened to be made a party to any proceeding (as defined in the TBOC), by reason of the fact that such person is or was a director or officer of the company, or is or was a director or officer of the company serving at the request of the company as a director, officer, partner, venturer, proprietor, trustee, employee, agent or similar functionary of another foreign or domestic corporation, partnership, joint venture, sole proprietorship, trust, employee benefit plan or other enterprise shall be indemnified by the company to the fullest extent that an enterprise is permitted to indemnify and advance expenses to such a person under the TBOC, or any amendment thereto or enactment of other applicable law as may from time to time be in effect (but, in the case of any such amendment or enactment, only to the extent that such amendment or law permits the company to provide broader indemnification rights than such law prior to such amendment or enactment permitted the company to provide), against judgments, penalties (including excise and similar taxes), fines, settlements and reasonable expenses (including court costs and attorneys’ fees) actually incurred by such person in connection with such proceeding. Expenses incurred in defending a proceeding shall be paid by the company in advance of the final disposition of such proceeding to the fullest extent permitted by the TBOC or any other applicable laws as may from time to time be in effect. The company’s obligation to indemnify and advance expenses shall arise, and all rights granted hereunder shall vest, at the time of the occurrence of the transaction or event to which the proceeding relates, or at the time that the action or conduct to which such proceeding relates was first taken or engaged in (or omitted to be taken or

F-4 - II-10

engaged in), regardless of when such proceeding is first threatened, commenced, or completed. The rights to indemnification and prepayment of expenses which are conferred upon the company’s directors and officers by the certificate of formation and bylaws may be conferred upon any employee or agent of the company if, and to the extent, authorized by the company’s board of directors. The company may purchase and maintain insurance or make other arrangements, at its expense, to protect itself and any such director, officer, employee, agent or person as specified in the certificate of formation and bylaws of the company, against any such expense, liability or loss, whether or not the company would have the power to indemnify against such expense, liability or loss under the TBOC. To the greatest extent permitted by applicable law, a director or officer of the company shall not be liable to the company or its shareholders for monetary damages for an act or omission in the director’s or officer’s capacity as a director or officer of the company except to the extent that the director or officer is found to be liable under applicable law for: (a) a breach of the person’s duty of loyalty to the company or its shareholders; (b) an act or omission not committed in good faith that (i) constitutes a breach of a duty owed by the person to the company or its shareholders or (ii) involves intentional misconduct or a knowing violation of law; (c) a transaction from which the person received an improper benefit, regardless of whether the benefit resulted from an action taken within the scope of the person’s duties; or (d) an act or omission for which the liability of the person is expressly provided by an applicable statute.

Pursuant to the agreement of limited partnership of Precision Drilling Company, LP, the partnership shall indemnify the general partner if it is named as a defendant or respondent in a proceeding because it was acting within the scope of its official capacity with the partnership. The partnership shall indemnify the limited partners and their officers, directors, employees and agents, the general partner and its officers, directors, employees and agents and any person serving at the request of the partnership, acting through the general partner, as director, officer, partner, trustee, employee or agent of another corporation, partnership, joint venture, trust or other enterprise (each an “indemnitee”) who is made a named defendant or respondent in a proceeding because such indemnitee was acting within the scope of his official capacity with the partnership, provided such indemnitee acted in good faith and reasonably believed that his conduct was in the best interest of the partnership. An indemnittee may be indemnified in a criminal proceeding only if he had no reasonable basis to believe his conduct was unlawful. The partnership shall not indemnify an indemnitee who is found liable on the basis that he improperly received personal benefit in violation of a fiduciary duty or that he committed other willful or intentional misconduct. Without limiting the foregoing provisions, the partnership may be required to indemnify an indemnitee to the full extent allowed by the TBOC. The partnership shall, with respect to claims for indemnity, be governed by the provisions of the TBOC in effect at the time the conduct subject to the indemnity claim arose.

Indemnification Agreements

In addition to the indemnification provisions included in the various corporate and organizational documents, Precision Drilling Corporation maintains indemnification agreements with individuals that are or have been officers or directors of Precision Drilling Corporation and its affiliates and individuals that are, have been or may become, at the request of Precision Drilling Corporation, an officer, director or trustee for a body corporate, limited liability company, partnership, unincorporated association, unincorporated syndicate, unincorporated organization, joint venture or trust. The indemnification agreements provide that Precision Drilling Corporation will indemnify and save harmless a party, the party’s estate, heirs and legal representatives against all costs, charges and expenses (including, without limitation, legal expenses), including an amount paid to settle an action or satisfy a judgment or any fines levied, reasonably incurred by him or her in respect of any actual or threatened civil, criminal or administrative action or proceeding to which he or she is made a party or threatened to be made a party by reason of being or having been an officer or director if (i) the party acted honestly and in good faith with a view to the best interests of the corporation or entity to which the party served as an officer or director and (ii) in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, the party had reasonable grounds for believing that his conduct was lawful. In respect of an actual or threatened action by or on behalf of a corporation that is a body corporate to procure a judgment in its favor to which the party, or the party’s estate, heirs or legal representations, is made a party or threatened to be

Should a party be compelled by law or requested by Precision Drilling Corporation or a related entity to participate in any action or proceeding without having been named as a party, by reason of being or having been an officer or director of a company, and thereby incur or become liable for any costs, charges or expenses (including, without limitation, legal expenses, counsel and witness fees), then, Precision Drilling Corporation shall forthwith assume and pay, or promptly reimburse the party for and indemnify the party from, any and all such costs, charges or expenses.

The exhibits to this registration statement are listed in the exhibit index, which appears elsewhere herein.

Item 22. | Undertakings.

(a) Each of the undersigned registrants hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering;

(4) To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Act need not be furnished, provided, that the Registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements;

(5) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser: each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other

F-4 - II-12

##### Table of Contents

than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use;

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities: The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(6) that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Each of the undersigned registrants hereby undertakes to: (i) respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means; and (ii) to arrange or provide for a facility in the U.S. for the purpose of responding to such requests. The undertaking in subparagraph (i) above includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

Each of the undersigned registrants hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
