          requirement in any such jurisdiction (other than, with respect to such
          first resales, any restrictions on transfer by reason of, among other
          things, a holder being a "control person" of Empire or Commonwealth
          for purposes of Canadian federal, provincial or territorial securities
          Laws).

     (b) As promptly as practicable after the date hereof, Empire shall file, if
     determined to be necessary, a registration statement on Form SB2 (or other
     applicable form) (the "Form SB2") in order to register under the 1933 Act
     the Empire Common Shares to be issued from time to time after the Effective
     Time upon exchange of the Exchangeable Shares (and redemption of the
     Redeemable Voting Shares) and shall use its reasonable efforts to cause the
     Form SB2 to become effective and to maintain the effectiveness of such
     registration for the period that such Exchangeable Shares remain
     outstanding.

     (c) As promptly as practicable after the Effective Date, Empire shall file
     a registration statement on Form S-8 (or other applicable form) (the "Form
     S-8") in order to register under the 1933 Act those Empire Common Shares to
     be issued from time to time after the Effective Time upon the exercise of
     the Replacement Options.

     (d) Commonwealth and Empire shall take all such steps as may be required to
     cause the transactions contemplated by Part 2 hereof and any other
     dispositions of Commonwealth equity securities and/or acquisitions of
     Empire equity securities (including, in each case derivative securities) in
     connection with this Agreement or the transactions contemplated hereby by
     any individual who is a director or officer of Commonwealth, to be exempt
     under Rule 16b-3 promulgated under the United States Securities Exchange
     Act of 1934, as amended (the "Exchange Act").

Preparation of Filings

2.7 Empire and Commonwealth shall cooperate in:

     (a) the preparation of any application for the orders and the preparation
     of any required registration statements and any other documents reasonably

     the Arrangement or the exercise of the Replacement Options; provided,
     however, that with respect to the United States "blue sky" and Canadian
     provincial qualifications neither Empire nor Commonwealth shall be required
     to register or qualify as a foreign corporation or to take any action that
     would subject it to service of process in any jurisdiction where such
     entity is not now so subject, except as to matters and transactions arising
     solely from the offer and sale of the Exchangeable Shares and the
     Redeemable Voting Shares; and

     (c) the taking of all such action as may be required under the CBCA in
     connection with the transactions contemplated by this Agreement and the
     Plan of Arrangement.

2.8 Each of Empire and Commonwealth shall furnish to the other all such
information concerning it and its shareholders as may be required (and, in the
case of its shareholders, available to it) for the effectuation of the actions
described in sections 2.5 and 2.6 and the foregoing provisions of this ss.2.7,
and each covenants that no information furnished by it (to its knowledge in the
case of information concerning its shareholders) in connection with such actions
or otherwise in connection with the consummation of the Arrangement and the
other transactions contemplated by this Agreement will contain any untrue
statement of a material fact or omit to state a material fact required to be
stated in any such document or necessary in order to make any information so
furnished for use in any such document not misleading in the light of the
circumstances in which it is furnished.

2.9 Empire and Commonwealth shall each promptly notify the other if at any time
before or after the Effective Time it becomes aware that the Circular or an
application for an order or a registration statement described in ss.2.6
contains any untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements contained
therein not misleading in light of the circumstances in which they are made, or
that otherwise requires an amendment or supplement to the Circular or such
application or registration statement. In any such event, Empire and
Commonwealth shall cooperate in the preparation of a supplement or amendment to
the Circular or such other document, as required and as the case may be, and, if
required, shall cause the same to be distributed to shareholders of Empire or
Commonwealth and/or filed with the relevant securities regulatory authorities.

<PAGE>


2.10 Commonwealth shall ensure that the Circular complies with all applicable
Laws and, without limiting the generality of the foregoing, that the Circular
does not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
contained therein not misleading in light of the circumstances in which they are
made (other than with respect to any information relating to and provided by the
Empire Parties or any third party that is not an affiliate of Commonwealth).
Without limiting the generality of the foregoing, Commonwealth shall ensure that
the Circular provides holders of Commonwealth Common Shares with information in
sufficient detail to permit them to form a reasoned judgment concerning the
matters to be placed before them at the Commonwealth Meeting and Empire shall
provide all information regarding it necessary to do so.

2.11 Empire shall ensure that the Form SB2 and Form S-8 comply with all
applicable Laws and, without limiting the generality of the foregoing, that such
documents do not contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements contained therein not misleading in light of the circumstances in
which they are made (other than with respect to any information relating to and
provided by Commonwealth or any third party that is not an affiliate of Empire)
and Commonwealth shall provide all information regarding it necessary to do so.

                                     Part 3

                         REPRESENTATIONS AND WARRANTIES

Representations and Warranties of Commonwealth

3.1 Commonwealth represents and warrants to and in favour of the Empire Parties
as follows and acknowledges that the Empire Parties are relying upon such
representations and warranties in connection with the matters contemplated by
this Agreement:

     (a) Organization.

          (i) Each of Commonwealth and the Material Subsidiaries has been duly
          incorporated or formed under all applicable Laws, is validly
          subsisting and has full corporate or legal power and authority to own
          its properties and conduct its businesses as currently owned and
          conducted. All of the outstanding shares and other ownership interests
          of the Material Subsidiaries which are held directly or indirectly by
          Commonwealth are validly issued, fully paid and non-assessable and all
          such shares and other ownership interests are owned directly or
          indirectly by Commonwealth, free and clear of all material liens,
          claims or encumbrances, except as set forth in the Commonwealth
          Disclosure Letter or pursuant to restrictions on transfers contained
          in constating documents, and except as aforesaid there are no
          outstanding options, rights, entitlements, understandings or
          commitments (contingent or otherwise) regarding the right to acquire
          any such shares or other ownership interests in any of the Material
          Subsidiaries. Commonwealth has disclosed in the Commonwealth
          Disclosure Letter the names and jurisdictions of incorporation of each
          of the Material Subsidiaries.

<PAGE>


          (ii) Neither Commonwealth nor any Material Subsidiary has any minority
          interest in any other corporation or entity, which minority interest
          is material in relation to the consolidated financial position of
          Commonwealth.

     (b) Capitalization. The authorized capital of Commonwealth consists of an
     unlimited number of Commonwealth Common Shares and an unlimited number of
     preferred shares, issuable in series. As of the date of this Agreement
     there are 34,578,544 Common Shares issued and outstanding, nil preferred
     shares issued and the number of Common Shares issuable on the exercise of
     Commonwealth Options and Warrants is 5,903,116 as more particularly
     described in Schedule G and including a 2 million unit private placement
     which will close before the Effective Date. Except as described in the
     preceding sentences of this ss.3.1(b), there are no options, warrants,
     conversion privileges or other rights, agreements, arrangements or
     commitments (pre-emptive, contingent or otherwise) obligating Commonwealth
     or any Material Subsidiary to issue or sell any shares of Commonwealth or
     any of the Material Subsidiaries or securities or obligations of any kind
     convertible into or exchangeable for any shares of Commonwealth, any
     Material Subsidiary or any other Person, nor is there outstanding any stock
     appreciation rights, phantom equity or similar rights, agreements,
     arrangements or commitments based upon the book value, income or any other
     attribute of Commonwealth or any subsidiary. There have been no
     Commonwealth Common Shares issued or purchased for cancellation since
     December 31, 1998. All outstanding Commonwealth Common Shares have been
     duly authorized and are validly issued and outstanding as fully paid and
     non-assessable shares, free of pre-emptive rights (except the 2 million
     units for which all funds have not yet been received). There are no
     outstanding bonds, debentures or other evidences of indebtedness of
     Commonwealth or any subsidiary having the right to vote (or that are
     convertible for or exercisable into securities having the right to vote)
     with the holders of the Commonwealth Common Shares on any matter. Except as
     set forth in the Commonwealth Disclosure Letter, there are no outstanding
     contractual obligations of Commonwealth or any of the Material Subsidiaries
     to repurchase, redeem or otherwise acquire any of its outstanding
     securities or with respect to the voting or disposition of any outstanding
     securities of any of the Material Subsidiaries.

     (c) Authority and No Violation.

          (i) Commonwealth has the requisite corporate power and authority to
          enter into this Agreement and to perform its obligations hereunder.
          The execution and delivery of this Agreement by Commonwealth and the
          consummation by Commonwealth of the transactions contemplated by this
          Agreement have been duly authorized by its Board of Directors and no
          other corporate proceedings on its part are necessary to authorize
          this Agreement, or the transactions contemplated hereby other than:

<PAGE>


               (A) with respect to the Circular and other matters relating
               solely thereto, including the implementation of the Arrangement,
               the approval of the Board of Directors of Commonwealth; and

               (B) with respect to the completion of the Arrangement, the
               approval of the Commonwealth Securityholders.

          (ii) This Agreement has been duly executed and delivered by
          Commonwealth and constitutes its legal, valid and binding obligation,
          enforceable against it in accordance with its terms, subject to
          bankruptcy, insolvency and other applicable Laws affecting creditors'
          rights generally, and to general principles of equity and to the fact
          that the Currency Act (Canada) precludes a court in Canada from giving
          judgment in' any currency other than Canadian currency.

          (iii) The Board of Directors of Commonwealth has

               (A) determined unanimously that the Arrangement is fair to the
               holders of the Commonwealth Common Shares and is in the best
               interests of Commonwealth,

               (B) received an opinion from Ross Glanville & Associates Ltd. to
               the effect that, as of the date of this Agreement, the Exchange
               Ratio or the Arrangement is fair from a financial point of view
               to the holders of the Commonwealth Common Shares, and

               (C) determined unanimously to recommend that the holders of the
               Commonwealth Common Shares vote in favour of the Arrangement.
               Commonwealth is not subject to a shareholder rights plan or
               "poison pill" or similar plan.

          (iv) The approval of this Agreement, the execution and delivery by
          Commonwealth of this Agreement and the performance by it of its
          obligations hereunder and the completion of the Arrangement and the
          transactions contemplated thereby, will not, except as disclosed in

                    incorporation, articles, by-laws or other charter documents,
                    including any unanimous shareholder agreement or any other
                    agreement or understanding relating to ownership of shares
                    or other interests or to corporate governance with any party
                    holding an ownership interest in any Material Subsidiary;

<PAGE>


                    (II) subject to obtaining the Appropriate Regulatory
                    Approvals relating to Commonwealth, any Laws, judgment or
                    decree except to the extent that the violation or breach of,
                    or failure to obtain any consent under, any Laws, judgment
                    or decree would not, individually or in the aggregate, have
                    a Material Adverse Effect on Commonwealth; or

                    (III) subject to obtaining the Appropriate Regulatory
                    Approvals relating to Commonwealth and except as would not,

               available credit of Commonwealth or any subsidiary to cease to be
               available other than as would not, individually or in the
               aggregate, have a Material Adverse Effect on Commonwealth;

               (C) except as would not, individually or in the aggregate, have a
               Material Adverse Effect on Commonwealth, result in the imposition
               of any encumbrance, charge or lien upon any of its assets or the
               assets of any Material Subsidiary, or restrict, hinder, impair or

     relating to Commonwealth and except as disclosed in the Commonwealth
     Disclosure Letter, neither Commonwealth nor any of its subsidiaries is in

     after notice or lapse of time or both, would constitute such a default

     Effect.

          subject to:

               (A) any Environmental Laws which requires or may require any
               work, repairs, construction, change in business practices or
               operations, or expenditures, including capital expenditures for
               facility upgrades, environmental investigation and remediation
               expenditures, or any other such expenditures;

               (B) any written demand or written notice with respect to the
               breach of or liability under any Environmental Laws applicable to
               Commonwealth or any subsidiary, including any regulations
               respecting the use, storage, treatment, transportation or
               disposition (including disposal or arranging for disposal) of
               Hazardous Substances;

               (C) any written demand or written notice with respect to
               liability, by contract or operation of applicable Laws, under
               Environmental Laws applicable to Commonwealth or any current or
               former subsidiary or any of their respective predecessor
               entities, divisions or any formerly owned, leased or operated
               properties or assets of the foregoing, including liability with
               respect to the presence, release or discharge of Hazardous
               Substances; or

               (D) any changes in the terms or conditions of any Environmental
               Permits or any renewal, modification, revocation, re-issuance,
               alteration, transfer or amendment of such Environmental Permits,
               or any review by, or approval of, any Governmental Entity of such
               Environmental Permits that are required in connection with the
               execution or delivery of this Agreement, the consummation of the
               transactions contemplated hereby or the continuation of business
               of Commonwealth or any subsidiaries following such consummation.

     (k) Tax Matters. Except as set forth in the Commonwealth Disclosure Letter:

          (i) Commonwealth and each of its subsidiaries have filed, or caused to
          be filed, all material Tax Returns required to be filed by them (all
          of which returns were correct and complete in all material respects)
          and have paid, or caused to be paid, all material amounts of Taxes
          shown to be due and payable thereon, and Commonwealth's most recently
          published financial statements contain an adequate provision in
          accordance with generally accepted accounting principles for all
          material amounts of Taxes payable in respect of each period covered by
          such financial statements and all prior periods to the extent such
          Taxes have not been paid, whether or not due and whether or not shown
          as being due on any Tax Returns. Commonwealth and each of its
          subsidiaries have made adequate provision in accordance with generally
          accepted accounting principles in their books and records for any
          material amounts of Taxes accruing in respect of any accounting period
          which has ended subsequent to the period covered by such financial
          statements.

<PAGE>


          (ii) Neither Commonwealth nor any subsidiary has received any written
          notification that any issues involving a material amount of Taxes have
          been raised (and are currently pending) by Revenue Canada, the United
          States Internal Revenue Service or any other taxing authority,
          including, without limitation, any sales tax authority, in connection
          with any of the Tax Returns referred to above and no waivers of
          statutes of limitations have been given or requested with respect to
          Commonwealth or any Material Subsidiary. To the best of the knowledge
          of Commonwealth, there are no proposed in writing (but unassessed)
          additional Taxes involving a material amount of Taxes and none has
          been asserted in writing. No Tax liens have been filed for material
          amounts of Taxes other than for Taxes not yet due and payable. Neither
          Commonwealth nor any of its subsidiaries (i) has made an election to
          be treated as a "consenting corporation" under Section 341(f) of the
          United States Internal Revenue Code (the "Code") or (ii) is a party to
          any Tax sharing or other similar agreement or arrangement of any
          nature with any other person (other than Commonwealth or any of its
          subsidiaries) pursuant to which Commonwealth or any of its
          subsidiaries has or could have any material liabilities in respect of
          Taxes, other than any liability arising under an agreement providing
          for the sale or other disposition of property by Commonwealth or any
          of its subsidiaries. Commonwealth has not made an election under
          Section 897(i) of the Code to be treated as a domestic corporation for
          purposes of Sections 897, 1445 and 6039C of the Code.

          (iii) "Urax" and "Taxes" means, with respect to any entity, all income
          taxes (including any tax on or based upon net income, gross income,
          income as specially defined, earnings, profits or selected items of
          income, earnings or profits) and all capital taxes, gross receipts
          taxes, environmental taxes, sales taxes, use taxes, ad valorem taxes,
          value added taxes, transfer taxes, franchise taxes, license taxes,
          withholding taxes, payroll taxes, employment taxes, Canada Pension
          Plan premiums, excise, severance, social security premiums, workers'
          compensation premiums, unemployment insurance or compensation
          premiums, stamp taxes, occupation taxes, premium taxes, property
          taxes, windfall profits taxes, alternative or add-on minimum taxes,
          goods and services tax, customs duties or other taxes, fees, imports,
          assessments or charges of any kind whatsoever, together with any
          interest and any penalties or additional amounts imposed by any taxing
          authority (domestic or foreign) on such entity, and any interest,
          penalties, additional taxes and additions to tax imposed with respect
          to the foregoing. For purposes of this ss.3.1(k), the term "material
          amount of Taxes" shall mean an amount of Taxes that is material to
          Commonwealth and its subsidiaries taken as a whole.

     (l) Pension and Employee Benefits.

          (i) Commonwealth has made available to Empire a list of all employee
          benefit, health, welfare, supplemental unemployment benefit, bonus,
          pension, profit sharing, deferred compensation, stock compensation,
          stock purchase, retirement, hospitalization insurance, medical,
          dental, legal, disability and similar plans or arrangements or
          practices, whether written or oral, which are maintained by
          Commonwealth and/or a Material Subsidiary (collectively referred to as
          the "Commonwealth Plans"). The Commonwealth Disclosure Letter states
          that none of the Commonwealth Plans constitute "employee pension
          benefit plans" (as defined in section 3(2) of the United States
          Employee Retirement Income Security Act of 1974, as amended ("ERISA"))
          or "employee welfare benefit plans" (as defined in section 3(1) of
          ERISA).

          (ii) No step has been taken, no event has occurred and no condition or
          circumstance exists that has resulted in or could reasonably be
          expected to result in any Commonwealth Plan being ordered or required
          to be terminated or wound up in whole or in part or having its
          registration under applicable Laws refused or revoked, or being placed
          under the administration of any trustee or receiver or regulatory
          authority or being required to pay any material Taxes, fees, penalties
          or levies under applicable Laws. There are no actions, suits, claims
          (other than routine claims for payment of benefits in the ordinary
          course), trials, demands, investigations, arbitrations or other
          proceedings which are pending or threatened in respect of any of the
          Commonwealth Plans or their assets which individually or in the
          aggregate would have a Material Adverse Effect on Commonwealth.

          (iii) Commonwealth has made available to Empire true, correct and
          complete copies of all of the Commonwealth Plans as amended (or, in
          the case of any unwritten Commonwealth Plan, a description thereof)
          together with all related documentation including, without limitation,
          funding agreements, actuarial reports, funding and financial
          information returns and statements with respect to each Commonwealth
          Plan, and current plan summaries, booklets and personnel manuals.
          Commonwealth has made available to Empire a true and complete copy of
          the most recent annual report on Form 5500 filed with the United
          States Internal Revenue Service with respect to each Commonwealth Plan
          in respect of which such a report was required.

          (iv) Other than as disclosed in the Commonwealth Disclosure Letter,
          all of the Commonwealth Plans are and have been established,.
          registered, qualified, invested and administered, in all material
          respects, in accordance with all applicable Laws, and in accordance
          with their terms and the terms of agreements between Commonwealth
          and/or a subsidiary, as the case may be, and their respective
          employees. To the knowledge of Commonwealth, no fact or circumstance
          exists that could adversely affect the existing tax status of a
          Commonwealth Plan.

<PAGE>


          (v) All obligations of Commonwealth or a Material Subsidiary regarding
          the Commonwealth Plans have been satisfied in all material respects.
          All contributions or premiums required to be made by Commonwealth
          and/or a Material Subsidiary, as the case may be, under the terms of
          each Commonwealth Plan or by applicable Laws have been made in a
          timely fashion in accordance with applicable Laws and the terms of the
          Commonwealth Plans.

          (vi) Other than as set forth in the Commonwealth Disclosure Letter or
          Publicly Disclosed by Commonwealth, each Commonwealth Plan is fully
          insured or fully funded and in good standing with such regulatory
          authorities as may be applicable and, as of the date hereof, no notice
          of under-funding, non-compliance, failure to be in good standing or
          otherwise has been received by Commonwealth or its subsidiaries from
          any such regulatory authority.

          (vii) There have been no improper withdrawals, applications or
          transfers of assets from any Commonwealth Plan or the trusts or other
          funding media relating thereto that remain outstanding and unremedied,
          and neither Commonwealth, nor any Material Subsidiary, nor any of
          their respective agents has been in breach of any fiduciary obligation
          with respect to the administration of the Commonwealth Plans or the
          trusts or other funding media relating thereto.

          (viii) No insurance policy or any other contract or agreement
          affecting any Commonwealth Plan requires or permits a retroactive
          increase in premiums or payments due thereunder.

     (m) Reports. Commonwealth has filed with the BCSC true and complete copies
     of all forms, reports, schedules, statements and other documents required
     to be filed by it since December 31, 1998 (such forms, reports, schedules,
     statements and other documents, including any financial statements or other
     documents, including any schedules included therein, are referred to as the
     "Commonwealth Documents"). The Commonwealth Documents at the time filed (i)
     did not contain any misrepresentation (as defined in the Securities Act)
     and (ii) complied in all material respects with the requirements of
     applicable securities Laws. Commonwealth has not filed any confidential
     material change report with the BCSC or any other securities authority or
     regulator or any stock exchange or other self-regulatory authority which at
     the date hereof remains confidential.

     (n) Compliance with Laws. Except as disclosed in the Commonwealth
     Disclosure Letter or Publicly Disclosed by Commonwealth, Commonwealth and
     the Material Subsidiaries have complied with and are not in violation of
     any applicable Laws, orders, judgments and decrees other than
     non-compliance or violations which would not, individually or in the
     aggregate, have a Material Adverse Effect on Commonwealth. Without limiting
     the generality of the foregoing, all securities of Commonwealth (including,
     all options, rights or other convertible or exchangeable securities) have
     been issued in compliance, in all material respects, with all applicable
     securities Laws and all securities to be issued upon exercise of any such
     options, rights and other convertible or exchangeable securities will be
     issued in compliance with all applicable securities Laws.

<PAGE>


     (o) Restrictions on Business Activities. Except as set forth in the
     Commonwealth Disclosure Letter or Publicly Disclosed by Commonwealth, there
     is no agreement, judgment, injunction, order or decree binding upon
     Commonwealth or any Material Subsidiary that has or could reasonably be
     expected to have the effect of prohibiting, restricting or materially
     impairing any business practice of Commonwealth or any Material Subsidiary,
     any acquisition of property by Commonwealth or any Material Subsidiary or
     the conduct of business by Commonwealth or any Material Subsidiary as
     currently conducted other than such agreements, judgments, injunctions,
     orders or decrees which would not, individually or in the aggregate, have a
     Material Adverse Effect on Commonwealth.

     (p) Material Customers. There is no single customer of Commonwealth or its
     subsidiaries, the loss of which would have a Material Adverse Effect on
     Commonwealth.

     (q) Intellectual Property. Except as set forth in the Commonwealth
     Disclosure Letter, Commonwealth and its subsidiaries own, or are validly
     licensed or otherwise have the right to use, all patents, patent rights,
     trade-marks, trade names, service marks, copyrights, know how and other
     proprietary intellectual property rights that are material to the conduct
     of the business, as presently conducted, of Commonwealth and its
     subsidiaries taken as a whole.

     (r) Insurance. Commonwealth has policies of insurance in force as of the
     date hereof naming Commonwealth as an insured which, having regard to the
     nature of such risk and the relative cost of obtaining insurance,
     Commonwealth believes are reasonable.

     (s) Property. Except as disclosed in the Commonwealth Disclosure Letter,
     Commonwealth and each Material Subsidiary have good and sufficient title to
     the real property interests including leases, easements, rights of way,
     permits or licences from land owners or authorities permitting the use of
     land by Commonwealth or such Material Subsidiary, necessary to permit the
     operation of its businesses as presently owned and conducted except for
     such failure of title that would individually or in the aggregate not have
     a Material Adverse Effect on Commonwealth.

     (t) Licences, Etc. Except as disclosed in the Commonwealth Disclosure
     Letter, Commonwealth and each Material Subsidiary owns, possesses, or has
     obtained and is in compliance with, all licences, permits, certificates,
     orders, grants and other authorizations of or from any Governmental Entity
     necessary to conduct its businesses as now conducted or as proposed to be
     conducted except for such failure that would individually or in the
     aggregate not have a Material Adverse Effect on Commonwealth.

     any right to compel Commonwealth to register or otherwise qualify such
     securities for public sale in Canada or the United States.

     or indirectly by Empire are validly issued, fully paid and non-assessable
     and all such shares and other ownership interests are owned directly or
     indirectly by Empire, free and clear of all material liens, claims or
     encumbrances except as disclosed by Empire to Commonwealth or pursuant to
     restrictions on transfer contained in constating documents, and there are
     no outstanding options, rights, entitlements, understandings or commitments
     (pre-emptive, contingent or otherwise) regarding the right to acquire any
     such shares of capital stock or other ownership interests in any of its
     subsidiaries.

     (b) Capitalization. The authorized capital of Empire consists of 50 million

     Other than under employee stock option plans, there are no outstanding
     contractual obligations of Empire to repurchase, redeem or otherwise
     acquire any of its outstanding securities or with respect to the voting or

          its part are necessary to authorize this Agreement, the Support
          Agreement and the Exchange Trust Agreement or the transactions
          contemplated hereby or thereby.

<PAGE>

                    incorporation, articles, by-laws or other charter documents,
                    including any unanimous shareholder agreement or any other
                    agreement or understanding relating to ownership of shares

                    (II) subject to obtaining the Appropriate Regulatory
                    Approvals relating to the Empire Parties, any Laws, judgment
                    or decree except to the extent that the violation or breach
                    of, or failure to obtain any consent under, any Laws,
                    judgment or decree would not, individually or in the
                    aggregate, have a Material Adverse Effect on Empire; or

                    (III) subject to obtaining the Appropriate Regulatory
                    Approvals relating to the Empire Parties and except as would
                    not, individually or in the aggregate, have a Material
                    Adverse Effect on Empire, any material contract, agreement,
                    license, franchise or permit to which it is party or by
                    which it is bound or is subject or is the beneficiary;

               (B) give rise to any right of termination or acceleration of
               indebtedness of any Empire Party or any Empire Material
               Subsidiary, or cause such indebtedness to come due before its
               stated maturity or cause any available credit of any Empire Party
               or any Empire Material Subsidiary to cease to be available; or

<PAGE>


               (C) except as would not, individually or in the aggregate, have a
               Material Adverse Effect on Empire, result in the imposition of
               any encumbrance, charge or lien upon any of its assets, or
               restrict, hinder, impair or limit its ability to carry on its
               business as and where it is now being carried on.

     No consent, approval, order or authorization of, or declaration or filing
     with, any Governmental Entity is required to be obtained by any of the
     Empire Parties or the Empire Material Subsidiaries in connection with the
     execution and delivery of this Agreement, the Support Agreement and the
     Exchange Trust Agreement or the consummation by any of the Empire Parties
     of the transactions contemplated hereby or thereby other than (A) the
     Appropriate Regulatory Approvals relating to the Empire Parties, (B) any
     filings required in connection with the creation and issue of the
     Redeemable Voting Share, (C) any approval required in connection with the
     amendment of the articles of Empire Exchangeco to create the Exchangeable
     Shares and (D) any other consents, approvals, orders, authorizations,
     declarations or filings of or with a Governmental Entity which, if not
     obtained, would not, individually or in the aggregate, have a Material
     Adverse Effect on Empire.

     (d) Absence of Certain Changes or Events. Except as Publicly Disclosed by
     Empire, since December 31, 1998 through to the date hereof each of the
     Empire Parties and each Empire Material Subsidiary has conducted its
     business only in the ordinary and regular course of business consistent
     with past practice and there has not occurred:

          (i) a Material Adverse Change with respect to Empire;

          (ii) any agreement or arrangement to take any action which, if taken
          prior to the date hereof, would have made any representation or
          warranty set forth in this Agreement materially untrue or incorrect as
          of the date when made;

          (iii) any resolution to approve a split, combination or
          reclassification of the Empire Common Shares; or

          (iv) any material change in its accounting methods, principles or
          practices.

     (e) Financial Statements. The audited consolidated financial statements for
     Empire as at and for each of the 12-month periods ended on December 31,
     1999 and 1998 and the unaudited consolidated financial statements for the
     nine-months ended September 30, 2000 have been prepared in accordance with
     United States generally accepted accounting principles, the requirements of
     applicable Governmental Entities and applicable securities Laws; such
     financial statements present fairly, in all material respects, the
     consolidated financial position and results of operations of Empire and its
     subsidiaries as of the respective dates thereof and for the respective
     periods covered thereby.

     Shares and Redeemable Voting Shares to be issued in connection with the
     Arrangement will be duly and validly issued by Empire Exchangeco and
     Empire, respectively, on the Effective Date as fully paid and
     non-assessable shares.

     (h) Empire Common Shares. The Empire Common Shares to be issued pursuant to
     the Arrangement or upon the exchange from time to time of the Exchangeable
     Shares or upon the exercise from time to time of the Replacement Options
     will, in all cases, be duly and validly issued by Empire on their
     respective dates of issue as fully paid and non-assessable shares.

     (i) Compliance with Laws. Except as disclosed in writing by Empire to
     Commonwealth or Publicly Disclosed by Empire, Empire and the Empire
     Material Subsidiaries have complied with and are not in violation of any
     applicable Laws, orders, judgments and decrees other than non-compliance or
     violations which would not, individually or in the aggregate, have a
     Material Adverse Effect on Empire. Without limiting the generality of the
     foregoing, all securities of Empire (including all options, rights or other
     convertible or exchangeable securities) have been issued in compliance in
     all material respects with all applicable securities Laws and all
     securities to be issued upon exercise of any such options, rights and other
     convertible or exchangeable securities will be issued in compliance with
     all applicable securities Laws.

     (j) Litigation, Etc. Except as disclosed in writing by Empire to
     Commonwealth or Publicly Disclosed by Empire, there is no claim, action,
     proceeding or investigation (including any native land claims) pending or,
     to the knowledge of Empire, threatened against Empire or any Empire
     Material Subsidiary before any court or Governmental Entity that, if
     adversely determined, would reasonably be expected to have a Material
     Adverse Effect on Empire, or prevent or materially delay consummation of
     the transactions contemplated by this Agreement or the Arrangement. Neither
     Empire nor any Empire Material Subsidiary, nor their respective assets and
     properties, is subject to any outstanding judgment, order, writ, injunction
     or decree that has had or is reasonably likely to have a Material Adverse
     Effect on Empire or that would prevent or materially delay consummation of
     the transactions contemplated by this Agreement or the Arrangement.

     (k) Tax Matters. Except as disclosed in writing by Empire to Commonwealth
     or Publicly Disclosed by Empire:

          (i) Empire and each of its subsidiaries have timely filed, or caused
          to be filed, all material Tax Returns required to be filed by them
          (all of which returns were correct and complete in all material
          respects) and have paid, or caused to be paid, all material amounts of
          Taxes shown to be due and payable thereon, and Empire's most recently
          published financial statements contain an adequate provision in
          accordance with generally accepted accounting principles for all
          material amounts of Taxes payable in respect of each period covered by
          such financial statements and all prior periods to the extent such
          Taxes have not been paid, whether or not due and whether or not shown
          as being due on any Tax Returns. Empire and each of its subsidiaries
          have made adequate provision in accordance with generally accepted
          accounting principles in their respective books and records for any
          Taxes accruing in respect of any accounting period which has ended
          subsequent to the period covered by such financial statements.

<PAGE>


          (ii) Neither Empire nor any subsidiary has received any written
          notification that any issues involving a material amount of Taxes have
          been raised (and are currently pending) by Revenue Canada, the United
          States Internal Revenue Service or any other taxing authority,
          including, without limitation, any sales tax authority, in connection
          with any of the Tax Returns referred to above and no waivers of
          statutes of limitations have been given or requested with respect to
          Empire or any subsidiary. To the best of the knowledge of Empire,
          there are no proposed (but unassessed) additional Taxes involving a
          material amount of Taxes and none has been asserted in writing. No Tax
          liens have been filed other than for Taxes not yet due and payable.
          Neither Empire nor any of its subsidiaries (i) has made an election to
          be treated as a "consenting corporation" under Section 341(f) of the
          Code or (ii) is a party to any Tax sharing or other similar agreement
          or arrangement of any nature with any other person (other than
          Commonwealth or any of its subsidiaries) pursuant to which Empire or
          any of its subsidiaries has or could have any material liabilities in
          respect of Taxes. Empire has not made an election under Section 897(i)
          of the Code to be treated as a domestic corporation for purposes of
          Sections 897, 1445 and 6039C of the Code.

     (l) Environmental. Except for matters that, individually or in the
     aggregate, would not have a Material Adverse Effect on Empire:

          (i) all operations of Empire and the Empire Material Subsidiary have
          been conducted, and are now, in compliance with all Environmental
          Laws; and

          (ii) Empire and the Empire Material Subsidiaries are in possession of,
          and in compliance with, all permits, authorizations, certificates,
          registrations, approvals and consents necessary under Environmental
          Laws to own, lease and operate their properties and conduct their
          respective businesses as they are now being conducted or as proposed
          to be conducted.

representations and warranties of another party to this Agreement.

               contained in this Agreement; and

     (f) the Empire Parties shall not take any action which may jeopardise the
     exchange of the Commonwealth Common Shares by holders of the Commonwealth
     Common Shares resident in Canada for the purposes of the Income Tax Act
     (Canada) from being treated on a tax deferred basis under the Income Tax
     Act (Canada) for holders who are otherwise eligible for such treatment.

Covenants Regarding Non-Solicitation

4.5  (a) Subject to ss.4.6, Commonwealth shall not, directly or indirectly,
     through any officer, director, employee, representative or agent of
     Commonwealth or any of its subsidiaries, (i) solicit, initiate or knowingly
     encourage (including by way of furnishing information or entering into any
     form of agreement, arrangement or understanding) the initiation of any
     inquiries or proposals regarding an Acquisition Proposal, (ii) participate
     in any discussions or negotiations regarding any Acquisition Proposal,
     (iii) withdraw or modify in a manner adverse to Empire the approval of the
     Board of Directors of Commonwealth of the transactions contemplated hereby,
     (iv) approve or recommend any Acquisition Proposal or (v) enter into any
     agreement, arrangement or understanding related to any Acquisition
     Proposal. Notwithstanding the preceding part of this ss.4.5(a) and any
     other provision of this Agreement, nothing shall prevent the Board of
     Directors of Commonwealth prior to the issuance of the Final Order from
     considering, participating in any discussions or negotiations, or entering
     into a confidentiality agreement and providing information pursuant to
     ss.4.5(c), regarding an unsolicited bona fide written Acquisition Proposal

<PAGE>


     that did not otherwise result from a breach of this ss.4.5 and that the
     Board of Directors of Commonwealth determines in good faith, after
     consultation with financial advisors and outside counsel, is reasonably
     likely to result in a Superior Proposal; provided, however, that prior to
     taking such action, the Board of Directors must receive advice of outside
     counsel that it is appropriate that the Board of Directors of Commonwealth
     take such action in order to discharge properly its fiduciary duties.
     Commonwealth shall not consider, negotiate, accept, approve or recommend an
     Acquisition Proposal after the date of the issuance of the Final Order.
     Commonwealth shall, and shall cause the officers, directors, employees,
     representatives and agents of Commonwealth and its subsidiaries to, cease
     immediately all discussions and negotiations regarding any proposal that
     constitutes, or may reasonably be expected to lead to, an Acquisition
     Proposal.

     (b) Commonwealth shall promptly notify Empire, at first orally and then in
     writing, of any Acquisition Proposal and any inquiry that could lead to an
     Acquisition Proposal, or any amendments to the foregoing, or any request
     for non-public information relating to Commonwealth or any Material
     Subsidiary in connection with an Acquisition Proposal or for access to the
     properties, books or records of Commonwealth or any Material Subsidiary by
     any Person that informs Commonwealth or such Material Subsidiary that it is
     considering making, or has made, an Acquisition Proposal. Such notice shall
     include a description of the material terms and conditions of any proposal,
     the identity of the Person making such proposal, inquiry or contact and
     provide such other details of the proposal, inquiry or contact as Empire
     may reasonably request. Commonwealth shall (i) keep Empire fully informed
     of the status including any change to the material terms of any such
     Acquisition Proposal or inquiry and (ii) provide to Empire as soon as
     practicable after receipt or delivery thereof with copies of all
     correspondence and other written material sent or provided to Commonwealth
     or any Material Subsidiary from any Person in connection with any
     Acquisition Proposal sent or provided by Commonwealth to any Person in
     connection with any Acquisition Proposal.

     (c) If Commonwealth receives a request for material non-public information
     from a Person who has made an unsolicited bona fide written Acquisition
     Proposal and Commonwealth is permitted, as contemplated under the second
     sentence of ss.4.5(a), to negotiate the terms of such Acquisition Proposal,
     then, and only in such case, the Board of Directors of Commonwealth may,
     subject to the execution by such Person of a confidentiality agreement
     containing a standstill provision substantially similar to that contained
     in the confidentiality agreement then in effect between Commonwealth and
     Empire, provide such Person with access to information regarding
     Commonwealth; provided, however, that the Person making the Acquisition
     Proposal shall not be precluded under such confidentiality agreement from
     making the Acquisition Proposal (but not any material amendment thereto)
     and provided further that Commonwealth sends a copy of any such
     confidentiality agreement to Empire promptly upon its execution and Empire
     is provided with a list of or copies of the information provided to such
     Person and immediately provided with access to similar information to which
     such Person was provided.

     (d) Commonwealth shall ensure that its officers, directors and employees
     and its subsidiaries and their officers, directors and employees and any
     financial advisors or other advisors or representatives retained by it are
     aware of the provisions of this ss.4.5, and it shall be responsible for any
     breach of this ss.4.5 by its officers, directors, employees, financial
     advisors or other advisors or representatives.

<PAGE>


     (e) Notwithstanding ss.4.5(a)(iii), the Board of Directors of Commonwealth
     may withdraw or modify in a manner adverse to Empire the approval of the
     Board of Directors of Commonwealth of the transactions contemplated hereby
     if a Specified Empire Event has occurred and is continuing.

Notice by Commonwealth of Superior Proposal Determination

4.6 Notwithstanding sections 4.5(a), (b), (d) and (e), Commonwealth may accept,
approve, recommend or enter into any agreement, understanding or arrangement in
respect of a Superior Proposal if, and only if, (i) it has provided Empire with
a copy of the Superior Proposal document, (ii) five Business Days shall have
elapsed from the later of the date Empire received written notice advising
Empire that Commonwealth's Board of Directors has resolved, subject only to
compliance with this ss.4.6 and termination of this Agreement, to accept,
approve, recommend or enter into an agreement in respect of such Superior
Proposal, specifying the terms and conditions of such Superior Proposal and
identifying the Person making such Superior Proposal, and the date Empire
received a copy of such Superior Proposal and (iii) it has previously or
concurrently will have (A) paid to Empire the break fee, if any, payable under
ss.6.4 and (B) terminated this Agreement pursuant to ss.6.3. Any information
provided by Commonwealth to Empire pursuant to this ss.4.6 or pursuant to ss.4.5
shall constitute "Information" under ss.4.7(b).

During such five Business Day period, Commonwealth agrees that Empire shall have
the right, but not the obligation, to offer to amend the terms of this
Agreement. The Board of Directors of Commonwealth will review any offer by
Empire to amend the terms of this Agreement in good faith in order to determine,
in its discretion in the exercise of its fiduciary duties, whether Empire's
offer upon acceptance by Commonwealth would result in such Superior Proposal
ceasing to be a Superior Proposal. If the Board of Directors of Commonwealth so
determines, it will enter into an amended agreement with Empire reflecting
Empire's amended proposal. If the Board of Directors of Commonwealth continues
to believe, in good faith and after consultation with financial advisors and
outside counsel, that such Superior Proposal remains a Superior Proposal and
therefore rejects Empire's amended proposal, Commonwealth may terminate this
Agreement pursuant to ss.6.3(c)(iv); provided, however, that Commonwealth must
concurrently pay to Empire the break fee, if any, payable to Empire under ss.6.4
and must concurrently with termination enter into a definitive agreement with
respect to such Acquisition Proposal. Commonwealth acknowledges and agrees that
payment of the break fee, if any, payable under ss.6.4 is a condition to valid
termination of this Agreement under ss.6.3(c)(iv) and this ss.4.6. Commonwealth
also acknowledges and agrees that each successive modification of any
Acquisition Proposal shall constitute a new Acquisition Proposal for purposes of
the requirement under clause (ii) of this ss.4.6 to initiate an additional five
Business Day notice period.

Access to Information

4.7  (a) Subject to sections 4.7(b) and (c) and applicable Laws, upon reasonable
     notice, each of Commonwealth and Empire shall (and shall cause each of
     their subsidiaries to) afford the other's officers, employees, counsel,
     accountants and other authorized representatives and advisors
     ("Representatives") access, during normal business hours from the date
     hereof and until the earlier of the Effective Date or the termination of
     this Agreement, to their properties, books, contracts and records as well
     as to its management personnel, and, during such period, Commonwealth and

<PAGE>


     Empire shall (and shall cause each of their subsidiaries to) furnish
     promptly to the other all information concerning that party's business,
     properties and personnel as the other may reasonably request. Nothing in
     the foregoing shall require a party to disclose information subject to a
     written confidentiality agreement with third parties or customer-specific
     or competitively sensitive information relating to areas or projects where
     a party is in direct competition with the other.

     (b) In accordance with the Confidentiality Agreement, each of Empire and
     Commonwealth acknowledges that certain information provided to it under
     ss.4.7(a) above will be non-public and/or proprietary in nature (the
     "Information"). Except as permitted below, each of Empire and Commonwealth
     will keep Information confidential and will not, without the prior written
     consent of the other, disclose it, in any manner whatsoever, in whole or in
     part, to any other Person, and will not use it for any purpose other than
     to evaluate the transactions contemplated by this Agreement. Each of Empire
     and Commonwealth will make all reasonable, necessary and appropriate
     efforts to safeguard the Information from disclosure to anyone other than
     as permitted hereby and to control the copies, extracts or reproductions
     made of the Information. The Information may be provided to the
     Representatives of each of Empire and Commonwealth who require access to
     the same to assist it in proceeding in good faith with the transactions
     contemplated by this Agreement and whose assistance is required for such
     purposes, provided that it has first informed such Representatives to whom
     Information is provided that the Representative has the same obligations,
     including as to confidentiality, restricted use and otherwise, that it has
     with respect to such Information. This provision shall not apply to such
     portions of the Information that: (i) are or become generally available to
     the public otherwise than as a result of disclosure by a party or its
     Representatives; or (ii) become available to a party on a non-confidential
     basis from a source other than, directly or indirectly, the other party or
     its Representatives, provided that such source is not to the knowledge of
     the first party, upon reasonable inquiry, prohibited from transmitting the
     Information by a contractual, legal or fiduciary obligation; (iii) were
     known to a party or were in its possession on a non-confidential basis
     prior to being disclosed to it by the other party or by someone on its
     behalf; or (iv) are required by applicable Laws or court order to be
     disclosed. The provisions of this ss.4.7(b) shall survive the termination
     of this Agreement.

     (c) The parties acknowledge that certain Information may be competitively
     sensitive and that disclosure thereof shall be limited to that which is
     reasonably necessary for the purpose of (i) preparing submissions or
     applications in order to obtain the Appropriate Regulatory Approvals, (ii)
     preparing the Circular, (iii) avoiding conflicts and (iv) integrating the
     operations of Empire and Commonwealth.

Closing Matters

4.8 Each of the Empire Parties and Commonwealth shall deliver, at the closing of
the transactions contemplated hereby, such customary certificates, resolutions
and other closing documents as may be required by the other parties hereto,
acting reasonably.

Indemnification

4.9  (a) Empire agrees that all rights to indemnification or exculpation now
     existing in favour of the directors or officers of Commonwealth or any
     subsidiary as provided in its articles of incorporation or by-laws in
     effect on the date hereof shall survive the Arrangement and shall continue
     in full force and effect for a period of not less than three years from the
     Effective Time and Empire hereby assumes, effective upon consummation of
     the Arrangement, all such liability with respect to any matters arising
     prior to the Effective Time.

     (b) There shall be maintained in effect, for not less than three years from
     the Effective Time, coverage equivalent to that in effect under the current
     policies of the directors' and officers' liability insurance maintained by
     Commonwealth or any of its subsidiaries, as the case may be, which is no
     less advantageous, and with no gaps or lapses in coverages with respect to
     matters occurring prior to the Effective Time.

Employment Agreements and Related Matters

4.10 Empire covenants and agrees, and after the Effective Time will cause
Commonwealth or any of its subsidiaries, as the case may be, and any successor
to Commonwealth to agree, to honour and comply with the terms of those existing
employment and severance agreements of Commonwealth or any of its subsidiaries,
as the case may be, which Commonwealth has disclosed in the Commonwealth
Disclosure Letter.

Prohibition on Voluntary Liquidation

4.11 The Empire Parties shall not, and agree to cause Empire Holdings to not,
take any action relating to a voluntary liquidation, dissolution or winding-up
of Empire Exchangeco or its successors or Empire Holdings or its successors, as
the case may be, prior to the Redemption Date (as defined in the Plan of
Arrangement).

                                   CONDITIONS

Mutual Conditions Precedent

5.1 The respective obligations of the parties hereto to complete the
transactions contemplated by this Agreement shall be subject to the

     Common Shares who are represented at the Commonwealth Meeting as well as

     accordance with any conditions in addition to those set out in ss.5.1(a)
     which may be imposed by the Interim Order;

     (c) the Interim Order and the Final Order shall each have been obtained in
     form and terms satisfactory to each of Commonwealth and Empire, acting

     unacceptable to such parties on appeal or otherwise;

     (d) there shall not be in force any order or decree restraining or
     enjoining the consummation of the transactions contemplated by this
     Agreement and there shall be no proceeding (other than an appeal made in
     connection with the Arrangement), of a judicial or administrative nature or
     otherwise, brought by a Governmental Entity in progress or threatened that
     relates to or results from the transactions contemplated by this Agreement
     that would, if successful, result in an order or ruling that would preclude
     completion of the transactions contemplated by this Agreement in accordance
     with the terms hereof or would otherwise be inconsistent with the
     Appropriate Regulatory Approvals which have been obtained;

     (e) Empire will have received conditional approval for the Empire Shares to
     be listed on either the AMEX market or the CDNX;

     (f) this Agreement shall not have been terminated pursuant to Part 6; and

<PAGE>

     Governmental Entity (including the Appropriate Regulatory Approvals), and
     the expiry of any waiting periods, in connection with, or required to
     permit, the consummation of the Arrangement, the failure of which to obtain
     or the non-expiry of which would constitute a criminal offence, or would
     have a Material Adverse Effect on Empire or Commonwealth, as the case may
     be, shall have been obtained or received on terms that will not have a
     Material Adverse Effect on Empire and/or Commonwealth; there shall not be
     pending or threatened any suit, action or proceeding by any Governmental
     Entity, in each case that has a reasonable likelihood of success, (i)
     seeking to prohibit or restrict the acquisition by Empire or any of its
     subsidiaries of any Commonwealth Common Shares, seeking to restrain or
     prohibit the consummation of the Plan of Arrangement or seeking to obtain
     from Commonwealth or Empire any damages that are material in relation to
     Commonwealth and its subsidiaries taken as a whole, (ii) seeking to
     prohibit or materially limit the ownership or operation by Empire or any of
     its subsidiaries of any material portion of the business or assets of
     Commonwealth or any of its subsidiaries or to compel Empire or any of its
     subsidiaries to dispose of or hold separate any material portion of the
     business or assets of Commonwealth or any of its subsidiaries, as a result
     of the Plan of Arrangement, (iii) seeking to impose limitations on the
     ability of Empire or any of its subsidiaries to acquire or hold, or

     Empire.

Additional Conditions Precedent to the Obligations of the Empire Parties

5.2 The obligations of the Empire Parties to complete the transactions
contemplated by this Agreement shall also be subject to the fulfilment of each
of the following conditions precedent (each of which is for the Empire Parties'
exclusive benefit and may be waived by Empire on behalf of the Empire Parties):

     (a) all covenants of Commonwealth under this Agreement to be performed on
     or before the Effective Date shall have been duly performed by Commonwealth
     in all material respects;

     (b) the representations and warranties of Commonwealth shall be true and
     correct in all material respects as of the Effective Date as if made on and
     as of such date (except to the extent such representations and warranties
     speak as of an earlier date, in which event such representations and
     warranties shall be true and correct in all material respects as of such
     earlier date, or except as affected by transactions contemplated or
     permitted by this Agreement) and the Empire Parties shall have received a
     certificate of Commonwealth addressed to the Empire Parties and dated the
     Effective Date, signed on behalf of Commonwealth by two senior executive
     officers of Commonwealth, confirming the same as at the Effective Date;

     (c) between the date hereof and the Effective Date, there shall not have
     occurred a Material Adverse Change to Commonwealth; and

     (d) the Board of Directors of Commonwealth shall have adopted all necessary
     resolutions, and all other necessary corporate action shall have been taken
     by Commonwealth and the subsidiaries to permit the consummation of the
     Arrangement.

The Empire Parties may not rely on the failure to satisfy any of the above
conditions precedent as a basis for non-compliance by the Empire Parties with
their obligations under this Agreement if the condition precedent would have
been satisfied but for a material default by the Empire Parties in complying
with their obligations hereunder.

Additional Conditions Precedent to the Obligations of Commonwealth

5.3 The obligations of Commonwealth to complete the transactions contemplated by
this Agreement shall also be subject to the following conditions precedent (each
of which is for the exclusive benefit of Commonwealth and may be waived by
Commonwealth):

<PAGE>


     (a) all covenants of the Empire Parties under this Agreement to be
     performed on or before the Effective Date shall have been duly performed by
     the Empire Parties in all material respects;

     (b) all representations and warranties of the Empire Parties under this
     Agreement shall be true and correct in all material respects as of the
     Effective Date as if made on and as of such date (except to the extent such
     representations and warranties speak as of an earlier date, in which event
     such representations and warranties shall be true and correct in all
     material respects as of such earlier date, or except as affected by
     transactions contemplated or permitted by this Agreement) and Commonwealth
     shall have received a certificate of each of the Empire Parties addressed
     to Commonwealth and dated the Effective Date, signed on behalf of each of
     the Empire Parties by two senior executive officers of the relevant Empire
     Party, confirming the same as at the Effective Date;

     (c) between the date hereof and the Effective Date, there shall not have
     occurred a Material Adverse Change to Empire; and

     (d) the Boards of Directors of the Empire Parties shall have adopted all
     necessary resolutions, and all other necessary corporate action shall have
     been taken by the Empire Parties to permit the consummation of the
     Arrangement and the issue of the Exchangeable Shares and Redeemable Voting
     Shares contemplated thereby and the issue of Empire Common Shares pursuant
     to the Arrangement and upon the exchange from time to time of the
     Exchangeable Shares and the exercise from time to time of the Replacement
     Options.

Commonwealth may not rely on the failure to satisfy any of the above conditions
precedent as a basis for non-compliance by Commonwealth with its obligations
under this Agreement if the condition precedent would have been satisfied but
for a material default by Commonwealth in complying with its obligations
hereunder.

Notice and Cure Provisions

5.4 The Empire Parties and Commonwealth will give prompt notice to the other of
the occurrence, or failure to occur, at any time from the date hereof until the
Effective Date, of any event or state of facts which occurrence or failure
would, or would be likely to:

     (a) cause any of the representations or warranties of the other party
     contained herein to be untrue or inaccurate in any material respect on the
     date hereof or on the Effective Date; or

     (b) result in the failure in any material respect to comply with or satisfy
     any covenant, condition or agreement to be complied with or satisfied by
     the other hereunder prior to the Effective Date.

Neither the Empire Parties nor Commonwealth may elect not to complete the
transactions contemplated hereby pursuant to. the conditions precedent contained
in sections 5.1, 5.2 and 5.3, or exercise any termination right arising
therefrom, unless forthwith and in any event prior to the filing of the Final
Order for acceptance by the Director, the Empire Parties or Commonwealth, as the
case may be, have delivered a written notice to the other specifying in
reasonable detail all breaches of covenants, representations and warranties or
other matters which the Empire Parties or Commonwealth, as the case may be, are
asserting as the basis for the non-fulfilment of the applicable condition

<PAGE>


precedent or the exercise of the termination right, as the case may be. If any
such notice is delivered, provided that the Empire Parties or Commonwealth, as
the case may be, are proceeding diligently to cure such matter, if such matter
is susceptible to being cured, the other may not terminate this Agreement as a
result thereof until the later of January 31, 2001 and the expiration of a
period of 30 days from such notice. If such notice has been delivered prior to
the date of the Commonwealth Meeting, such meeting shall be postponed until the
expiry of such period. If such notice has been delivered prior to the making of
the application for the Final Order or the filing of the Articles of Arrangement
with the Director, such application and such filing shall be postponed until the
expiry of such period. For greater certainty, in the event that such matter is
cured within the time period referred to herein, this Agreement may not be
terminated.

Satisfaction of Conditions

5.5 The conditions precedent set out in ss.5.1, ss.5.2 and ss.5.3 shall be
conclusively deemed to have been satisfied, waived or released when, with the
agreement of Empire and Commonwealth, a certificate of arrangement in respect of
the Arrangement is issued by the Director.

                                     Part 6

                            AMENDMENT AND TERMINATION

Amendment

6.1 This Agreement may, at any time and from time to time before or after the
holding of the Commonwealth Meeting but not later than the Effective Date, be
amended by mutual written agreement of the parties hereto, and any such
amendment may, without limitation:

     (a) change the time for performance of any of the obligations or acts of
     the parties;

     (b) waive any inaccuracies or modify any representation contained herein or
     in any document delivered pursuant hereto;

     (c) waive compliance with or modify any of the covenants herein contained
     and waive or modify performance of any of the obligations of the parties;
     and

     (d) waive compliance with or modify any conditions precedent herein
     contained; provided, however, that any such change, waiver or modification
     does not invalidate any required security holder approval of the
     Arrangement.

Mutual Understanding Regarding Amendments

6.2  (a) The parties will continue, from and after the date hereof and through
     and including the Effective Date, to use their respective reasonable
     efforts to maximize present and future financial and tax planning
     opportunities for the shareholders of Commonwealth, and for Empire and for
     Commonwealth as and to the extent that the same shall not prejudice any
     party or its security holders. The parties will ensure that such planning
     activities do not impede the progress of the Arrangement in any material
     way.

<PAGE>


     (b) The parties agree that if the Empire Parties or Commonwealth, as the
     case may be, propose any amendment or amendments to this Agreement or to
     the Plan of Arrangement, the other will act reasonably in considering such
     amendment and if the other and its shareholders are not prejudiced by
     reason of any such amendment the other will co-operate in a reasonable
     fashion with the Empire Parties or Commonwealth, as the case may be, so
     that such amendment can be effected subject to applicable Laws and the
     rights of the security holders.

Termination

6.3  (a) If any condition contained in ss.5.1 or ss.5.2 is not satisfied at or
     before the Effective Date to the satisfaction of the Empire Parties, then
     Empire on behalf of the Empire Parties may by notice to Commonwealth
     terminate this Agreement and the obligations of the parties hereunder
     except as otherwise herein provided, but without detracting from the rights
     of the Empire Parties arising from any breach by Commonwealth but for which
     the condition would have been satisfied.

     (b) If any condition contained in ss.5.1 or ss.5.3 is not satisfied at or
     before the Effective Date to the satisfaction of Commonwealth, then
     Commonwealth may by notice to Empire on behalf of the Empire Parties
     terminate this Agreement and the obligations of the parties hereunder
     except as otherwise herein provided, but without detracting from the rights
     of Commonwealth arising from any breach by the Empire Parties but for which
     the condition would have been satisfied.

     (c) This Agreement may:

          (i) be terminated by the mutual agreement of Commonwealth and the
          Empire Parties (without further action on the part of the Commonwealth
          Securityholders if terminated after the holding of the Commonwealth
          Meeting);

          (ii) be terminated by either Commonwealth or Empire, if there shall be
          passed any law or regulation that makes consummation of the
          transactions contemplated by this Agreement illegal or otherwise
          prohibited or if any injunction, order or decree enjoining Empire or
          Commonwealth from consummating the transactions contemplated by this
          Agreement is entered and such injunction, order or decree shall become
          final and non-appealable;

          (iii) be terminated by Empire if (A) the Board of Directors of
          Commonwealth shall have failed to recommend or withdrawn or modified
          or changed in a manner adverse to Empire its approval or
          recommendation of this Agreement or the Arrangement or shall have
          recommended an Acquisition Proposal or (B) through the fault of
          Commonwealth (whether by commission or omission), this Arrangement is
          not, prior to 14 days prior to the Termination Date, submitted for the
          approval of the Commonwealth Securityholders at the Commonwealth
          Meeting;

<PAGE>


          (iv) be terminated by Commonwealth in order to enter into a definitive
          written agreement with respect to a Superior Proposal, subject to
          compliance with ss.4.6 and the payment of any fee required to be paid
          pursuant to ss.6.4(a); or

          (v) be terminated by Commonwealth or Empire if Commonwealth
          Securityholder approval shall not have been obtained by reason of the
          failure to obtain the required vote at the Commonwealth Meeting; in
          each case, prior to the Effective Date.

     (d) If the Effective Date does not occur on or prior to the Termination
     Date, then this Agreement shall terminate.

     (e) If this Agreement is terminated in accordance with the foregoing
     provisions of this ss.6.3, no party shall have any further liability to
     perform its obligations hereunder except as provided in ss.6.4 and as
     otherwise contemplated hereby, and provided that, subject to ss.6.5,
     neither the termination of this Agreement nor anything contained in this
     ss.6.3(e) shall relieve any party from any liability for any breach by it
     of this Agreement, including from any inaccuracy in its representations and
     warranties and any non-performance by it of its covenants made herein.

Break Fee

6.4  (a) If:

          (i) Commonwealth shall terminate this Agreement pursuant
          toss.6.3(c)(iv), unless at the time of such termination, a Specified
          Empire Event has occurred and is continuing;

          (ii) Empire shall terminate this Agreement pursuant to ss.6.3(c)(iii),
          unless at the time of such failure to recommend, withdrawal or adverse
          modification or change, or recommendation of an Acquisition Proposal,
          a Specified Empire Event has occurred and is continuing; or

          (iii) either Commonwealth or Empire shall terminate this Agreement
          pursuant to ss.6.3(c)(v) in circumstances where Commonwealth
          Securityholder approval has not been obtained at the Commonwealth
          Meeting, and (x) a bona fide Acquisition Proposal has been made by any
          person other than a Empire Party prior to the Commonwealth Meeting and
          not withdrawn more than five days prior to the vote of the
          Commonwealth Securityholders and (y) Commonwealth enters into an
          agreement with respect to an Acquisition Proposal, or an Acquisition
          Proposal is consummated, after the date hereof and prior to the
          expiration of 18 months following termination of this Agreement,
          unless at the time of the Commonwealth Meeting a Specified Empire
          Event has occurred and is continuing;

     then in any such case Commonwealth shall pay to Empire US$10,000 in
     immediately available funds to an account designated by Empire. Such
     payment shall be due (A) in the case of a termination specified in clause
     (i), prior to the termination of this Agreement, (B) in the case of a
     termination specified in clause (ii), within five Business Days after
     written notice of termination by Empire or (C) in the case of a termination
     specified in clause (iii), at or prior to the earlier of the entering into
     of the agreement and the consummation of the transaction referred to
     therein. Commonwealth shall not be obligated to make more than one payment
     pursuant to this ss.6.4(a).

<PAGE>


     (b) If the holders of the Commonwealth Common Shares shall fail to approve
     the Arrangement (unless a Specified Empire Event has occurred and is
     continuing) at the Commonwealth Meeting, then at 11:00 a.m., Vancouver
     time, on the first Business Day following the Commonwealth Meeting,
     Commonwealth shall pay to Empire US$10,000 as payment in full of the Empire
     Parties' out-of-pocket costs and expenses in connection with the
     transaction contemplated by this Agreement in immediately available funds
     to an account designated by Empire. Any payment due under ss.6.4(a) shall
     be reduced dollar-for-dollar by any payment previously made under this
     ss.6.4(b).

Effect of Break Fee Payment

6.5 For greater certainty, the parties hereto agree that if Commonwealth pays to
Empire amounts required by ss.6.4(a) as a result of the occurrence of any of the
events referenced in ss.6.4(a), the Empire Parties shall have no other remedy
for any breach of this Agreement by Commonwealth.

Remedies

6.6 Subject to ss.6.5, the parties hereto acknowledge and agree that an award of
money damages would be inadequate for any breach of this Agreement by any party
or its representatives and any such breach would cause the non-breaching party
irreparable harm. Accordingly, the parties hereto agree that, in the event of
any breach or threatened breach of this Agreement by one of the parties, the
non-breaching party will also be entitled, without the requirement of posting a
bond or other security, to equitable relief, including injunctive relief and
specific performance. Such remedies will not be the exclusive remedies for any
breach of this Agreement but will be in addition to all other remedies available
at law or equity to each of the parties.

                                   SCHEDULE A
                           Form of Affiliate's Letter
Dear Sirs:

The undersigned, a holder of common shares ("Commonwealth Common Shares") of
Commonwealth Energy Corp. ("Commonwealth"), a corporation existing under the
laws of Canada is entitled to receive in connection with the arrangement
pursuant to Section 192 of the Canada Business Corporations Act, R.S.C. 1995, c.
C-44 (the "Arrangement") to be entered into pursuant to the Merger Agreement
dated as of December __, 2000 among Commonwealth, Empire Energy Corporation, a
corporation existing under the laws of the State of Utah ("Empire"), and Empire
Exchangeco Ltd., a company existing under the laws of Canada ("Empire
Exchangeco"), exchangeable shares (the "Exchangeable Shares") of Empire
Exchangeco. The undersigned acknowledges that the undersigned may be deemed an
"affiliate" of Empire within the meaning of Rule 145 ("Rule 145") promulgated
under the U.S. Securities Act of 1933, as amended (the "Securities Act"), by the
U.S. Securities and Exchange Commission (the "SEC"), although nothing contained
herein should be construed as an admission of such fact or a waiver of any
rights the undersigned may have to object to any claim that the undersigned is
such an affiliate. If in fact the undersigned were such an affiliate, the
undersigned's ability to sell, assign or transfer:

     (a) the Exchangeable Shares received by the undersigned in exchange for any
     Commonwealth Common Shares in connection with the Arrangement; and

     (b) any shares of common stock of Empire (collectively, with the
     Exchangeable Shares, the "Securities") for which the Exchangeable Shares
     may be exchanged;

may be restricted unless such transaction is registered under the Securities Act
or an exemption from such registration is available. The undersigned understands
that such exemptions are limited and the undersigned has obtained or will obtain
advice of counsel as to the nature and conditions of such exemptions, including
information with respect to the applicability to the sale of the Securities of
Rules 144 and 145(d) promulgated under the Securities Act. The undersigned
understands that Empire will not be required to maintain the effectiveness of
any registration statement under the Securities Act for the purpose of resale of
Securities by the undersigned.

The undersigned hereby represents and covenants with Empire that the undersigned
will not sell, assign or transfer any of the Securities received by the
undersigned in exchange for Commonwealth Common Shares in connection with the
Arrangement except:

     (a) pursuant to an effective registration statement under the Securities
     Act;

     (b) in conformity with Rule 145; or

     (c) in a transaction which, in the opinion of the general counsel of Empire
     or other counsel reasonably satisfactory to Empire or as described in a
     "no-action" or interpretative letter from the staff of the SEC specifically
     issued with respect to a transaction to be engaged in by the undersigned,
     is not required to be registered under the Securities Act.

In the event of a sale or other disposition by the undersigned of Securities
pursuant to Rule 145, the undersigned will supply Empire with evidence of
compliance with such Rule, in the form of a letter substantially in the form of
Annex I hereto.

Empire covenants that it will take all such actions as may be reasonably
available to it to permit the sale or other disposition of Securities by the
undersigned under Rule 145 in accordance with the terms thereof.

<PAGE>


The undersigned also understands that there will be placed on any certificates
for the Securities issued to the undersigned a legend stating in substance:

"THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION TO
WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES. THE
SECURITIES REPRESENTED BY THIS CERTIFICATE MAY BE SOLD, TRANSFERRED OR OTHERWISE
DISPOSED OF ONLY IN ACCORDANCE WITH THE TERMS OF A LETTER AGREEMENT BETWEEN THE
REGISTERED HOLDER HEREOF AND EMPIRE ENERGY CORP., A COPY OF WHICH AGREEMENT IS
ON FILE AT THE PRINCIPAL OFFICES OF EMPIRE ENERGY CORPORATION."

The undersigned also understands that unless a sale or transfer by the
undersigned of the undersigned's Securities has been registered under the Act or
is a sale made in conformity with the provisions of Rule 145 under the Act,
Empire reserves the right to put the following legend on the certificates issued
to the undersigned's transferee:

"THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM A PERSON WHO RECEIVED SUCH
SECURITIES IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES
ACT OF 1933 APPLIES. THE SECURITIES HAVE NOT BEEN ACQUIRED BY THE HOLDER WITH A
VIEW TO, OR FOR RESALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE
MEANING OF THE SECURITIES ACT OF 1933 AND MAY NOT BE SOLD, TRANSFERRED OR
OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT OR
IN ACCORDANCE WITH AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
SECURITIES ACT OF 1933."

It is understood and agreed that the legends set forth above shall be removed by
delivery of substitute certificates without such legend if (i) the securities
represented thereby have been registered for sale by the undersigned under the
Securities Act or (ii) Empire has received either an opinion of counsel, which
opinion and counsel shall be reasonably satisfactory to Empire, or a "no-action"
letter obtained by the undersigned from the staff of the Commission, to the
effect that the restrictions imposed by Rule 145 under the Act no longer apply
to the undersigned. The undersigned acknowledges that:

     (a) the undersigned has carefully read this letter and understands the
     requirements hereof and the limitations imposed upon the distribution,
     sale, transfer or other disposition of the Securities, and

     (b) the receipt by Empire and Empire Exchangeco of this letter is an
     inducement to Empire and Empire Exchangeco to consummate the Agreement.

Very truly yours,



DATED:


Accepted and agreed to this _____ day of ___________, 2000.
