     indirectly, controls, is controlled by or is under common control with such
     Person (excluding any trustee under, or any committee with responsibility
     for administering, any Pension Plan or Welfare Plan). A Person shall be
     deemed to be "controlled by" any other Person if such other Person
     possesses, directly or indirectly, power to direct or cause the direction
     of the management and policies of such Person whether by contract or
     otherwise.

     "Authorised Representative" means, relative to the Guarantor, those of its
     officers and employees whose signatures and incumbency shall have been

     to invest in, a debtor, or otherwise to assure a creditor against loss) the
     indebtedness, obligation or any other liability of any other Person (other

     Contingent Liability shall (subject to any limitation set forth therein) be
     deemed to be the outstanding principal amount of the debt, obligation or
     other liability guaranteed thereby; provided, however, that if the maximum
     amount of the debt, obligation or other liability guaranteed thereby has
     not been established, the amount of such Contingent Liability shall be the
     maximum reasonably anticipated amount of the debt, obligation or other
     liability; provided further, however, that any agreement to limit the
     maximum amount of such Person's obligation under such Contingent Liability

     secured or supported by a guarantee, letter of credit or other form of
     credit enhancement. If Moody's or S&P shall have changed its system of

     considered to be at or above a specified level if it is at or above the new
     rating which most closely corresponds to the specified level under the old
     rating system.

     (whether or not known to the Facility Agent, any Bank or the Guarantor)
     other than the irrevocable payment to the Banks of all amounts payable
     hereunder. Nothing shall impair or discharge the Guarantor's liability or
     obligations under this Guarantee and this shall apply, without limitation,
     in relation to:

     2.2.1  anything which would have discharged the Guarantor (wholly or in
            part) whether as surety, co-obligor or otherwise or which would have
            afforded the Guarantor any legal or equitable defence; or

     2.2.2  the existence or validity or the taking or renewal of any other
            guarantee or security taken by the Banks in relation to the Facility
            Agreement, or any enforcement of or failure to enforce or the

            security or other document relating to the Facility Agreement, or

            with or without the consent of the Guarantor; or

     2.2.4  any release of, or granting of time or any other indulgence to, the
            Borrower or any other person; or

     2.2.5  any winding up, dissolution, reconstruction, arrangement or
            reorganisation, legal limitation, disability, incapacity or lack of
            corporate power or authority or other circumstances of, or any
            change in the constitution or corporate identity or loss of
            corporate identity by, the Borrower or any other person (or any act
            taken by the Guarantor or the Borrower in relation to any such
            event); or

     2.2.6  any other circumstances which might render void or unenforceable the
            obligations, commitments and undertakings of the Borrower under the
            Facility Agreement, or which might affect the Banks' ability to
            recover amounts from the Borrower thereunder; or

     2.2.7  any defence or counterclaim which the Borrower may be able to assert
            against the Banks.

2.3  Any amounts payable under this Guarantee shall be paid in full without any
     deduction or withholding whatsoever (whether in respect of set-off,
     counterclaim, duties, charges, Taxes or otherwise) unless such deduction or
     withholding is required by law. If such a deduction or withholding is
     required the Guarantor shall forthwith pay to the Facility Agent an
     additional amount calculated to ensure that the net amount received by the
     Banks (taking into account any deduction or withholding required on the
     additional amount) will equal the full amount which would have been
     received by it had no such deduction or withholding been made.

2.4  As a separate, additional continuing and primary obligation, the Guarantor,
     unconditionally and irrevocably, undertakes to indemnify the Banks on
     demand by the Facility Agent (without requiring the Facility Agent to first
     take steps against the Borrower or any other person) against any loss
     suffered or incurred by the Banks should the amounts which would otherwise
     be due under Clause 2.1 above not be recoverable for any reason whatsoever,
     including (but not limited to) the Facility Agreement being or

--------------------------------------------------------------------------------
<PAGE>

     becoming void, voidable or unenforceable, the amount of that loss being the
     amount expressed to be payable by the Borrower in respect of the relevant
     sum.

2.5  Demands may be made by the Facility Agent under this Guarantee from time to
     time and irrespective of whether any demands, steps or proceedings are
     being or have been taken against the Borrower or any other person.

2.6  The Guarantor's obligations under this Guarantee are and will remain in
     full force and effect by way of continuing security until no sum remains to
     be lent under the Facility Agreement and the Finance Parties have received
     or recovered all sums payable under the Facility Agreement.

2.7  So long as any sum remains to be lent or remains payable under the Facility
     Agreement, the Guarantor shall not, after a claim has been made or by
     virtue of any payment or performance by it under this Guarantee for or on
     account of the liabilities of the Borrower:

     2.7.1  be subrogated to any rights, security or moneys held, received or
            receivable by the Facility Agent or any of the other Finance Parties
            or be entitled to any right of contribution or indemnity in respect
            of any payment made or monies received on account of the Guarantor's
            liability under this Guarantee;

     2.7.2  claim, rank, prove or have the benefit of any payment, distribution
            or security from or on account of the Borrower or exercise any right
            of set-off as against the Borrower

     unless the Facility Agent otherwise directs.

            (i)    contravene the Guarantor's Organic Documents;

--------------------------------------------------------------------------------
<PAGE>

            (ii)   contravene any law, governmental regulation, court decree or
                   order or material Contractual Obligation binding on or
                   affecting the Guarantor; or

            (iii)  result in, or require the creation or imposition of, any Lien
                   on any of the Guarantor's properties.

     3.1.3  Governmental Approval; Regulation:

            (i)    No authorisation, consent, approval, licence, exemption of or
                   filing or registration with any court or governmental
                   authority or regulatory body ("Governmental Approval") is
                   required for the Guarantor to execute and perform its
                   obligations under this Guarantee, except for those which have
                   been duly obtained or effected. No material Governmental
                   Approval is required for the Guarantor to carry on its
                   business, except for those which have been duly obtained or
                   effected.

            (ii)   The Guarantor is not subject to any regulation as an
                   "investment company" subject to the U.S. Investment Company
                   Act of 1940, as amended, or as a "holding company" or a
                   "subsidiary company" or an "affiliate" of a "holding company"
                   subject to the U.S. Public Utility Holding Company Act of
                   1935, as amended ("PUHCA"), except that the Guarantor is a
                   "subsidiary company" of Edison International which is a
                   "holding company" that is exempt from all regulation under
                   PUHCA (except Section 9(a)(2) thereof) pursuant to Section
                   3(a) thereof. The Guarantor is not otherwise subject to any
                   regulation as a "public utility" under any other applicable
                   law, rule or regulation, which would have Material Adverse
                   Effect.

     3.1.4  Validity: This Guarantee constitutes the legal, valid and binding
            obligations of the Guarantor enforceable in accordance with its
            terms (except as may be limited by bankruptcy, insolvency or other
            similar laws affecting the enforcement of creditors' rights
            generally and general principles of equity).

     3.1.5  Financial Information: The consolidated balance sheets of the
            Guarantor (as at 31 December 1997 and 31 December 1998, and the
            related consolidated statements of income and cash flows of the
            Guarantor, copies of which have been furnished to the Facility
            Agent, have been prepared in accordance with US GAAP consistently
            applied, and present fairly the consolidated financial condition of
            the Guarantor and its Subsidiaries as at the dates thereof and the
            results of their operations for the periods then ended.

     3.1.6  No Material Adverse Change: There has not occurred any event or
            condition having a Material Adverse Effect since 31 December 1998.

     3.1.7  Litigation: There is no pending or, to the knowledge of the
            Guarantor, threatened litigation, action, proceeding, or labour
            controversy affecting the Guarantor, or any of its properties,
            businesses, assets or revenues, which, if adversely determined
            (taking into account any insurance proceeds payable under a policy
            where the insurer has accepted coverage without any reservations),
            would have a Material

--------------------------------------------------------------------------------
<PAGE>

            Adverse Effect or which purports to affect adversely the legality,
            validity or enforceability of this Guarantee.

     3.1.8  Ownership of Properties: The Guarantor owns good and marketable
            title to, or a valid leasehold interest in or other enforceable
            interest in all properties and assets, real and personal, tangible
            and intangible, of any nature whatsoever (including patents,
            trademarks, trade names, service marks and copyrights) purported to
            be owned, leased or held by it, free and clear of all Liens, charges
            or claims (including infringement claims with respect to patents,
            trademarks, copyrights and the like) except as permitted pursuant to
            Clause 4.2.2.

     3.1.9  Taxes: The Guarantor has filed all tax returns and reports required
            by law to have been filed by it and has paid all taxes and
            governmental charges thereby shown to be owing, except any such
            taxes or charges which are being diligently contested in good faith
            by appropriate proceedings and for which adequate reserves in
            accordance with US GAAP shall have been set aside on its books.

     3.1.10 Pension and Welfare Plans: During the consecutive 12 month period
            prior to the date of the execution and delivery of this Guarantee
            and prior to the Issue Date (as defined in the Facility Agreement),
            no steps have been taken to terminate any Pension Plan, and no
            contribution failure has occurred with respect to any Pension Plan
            sufficient to give rise to a Lien under Section 302(f) of ERISA. No
            condition exists or event or transaction has occurred with respect
            to any Pension Plan which could reasonably be expected to result in
            the incurrence by the Guarantor or any member of the Controlled
            Group of any material liability (other than liabilities incurred in
            the ordinary course of maintaining the Pension Plan), fine or
            penalty. Neither the Guarantor nor any member of the Controlled
            Group has any contingent liability with respect to any post-
            retirement benefit under a Welfare Plan which could reasonably be
            expected to have a Material Adverse Effect, other than liability for
            continuation coverage described in Part 6 of Title I of ERISA.

     3.1.11 Environmental Warranties:

            (i)    All facilities and property owned or leased by the Guarantor
                   or any of its Subsidiaries or Partnerships have been, and
                   continue to be, owned or leased by the Guarantor, its
                   Subsidiaries or Partnership, as the case may be, in
                   compliance with all Environmental Laws, except where the
                   failure so to comply would not have, or be reasonably
                   expected to have, a Material Adverse Effect.

            (ii)   There are no pending or, to the knowledge of the Guarantor,
                   threatened:

                   (a)  material claims, complaints, notices or requests for
                        information received by the Guarantor from governmental
                        authorities with respect to any alleged violation by the
                        Guarantor of any Environmental Law; or

--------------------------------------------------------------------------------
<PAGE>

                   (b)  material complaints, notices or inquiries to the
                        Guarantor from governmental authorities regarding
                        potential liability under any Environmental Law.

            (iii)  There have been no Releases (as defined under any
                   Environmental Law) of Hazardous Materials at, on or under any
                   property now or previously owned or leased by the Guarantor
                   that, singly or in the aggregate, have, or may reasonably be
                   expected to have, a Material Adverse Effect.

            (iv)   The Guarantor has obtained and is in compliance with all
                   permits, certificates, approvals, licences and other
                   authorisations relating to environmental matters and
                   necessary for the Guarantor's business, except where the
                   failure to obtain, maintain or comply with such permits,
                   certificates, approvals, licences or other authorisations
                   would not have, or be reasonably expected to have, a Material
                   Adverse Effect.

            (vi)   No property now or previously owned or leased by the
                   Guarantor is listed or proposed for listing (with respect to
                   owned property only) on the U.S. National Priorities List
                   pursuant to any Environmental Law, on the CERCLIS or on any
                   similar state list of sites requiring investigation or clean-
                   up.

            (vi)   No conditions exist at, on or under any property now or
                   previously owned or leased by the Guarantor which, with the
                   passage of time, or the giving of notice or both, would give
                   rise to liability under any Environmental Law which liability
                   would have, or may reasonably be expected to have, a Material
                   Adverse Effect.

     3.1.12 Regulations T, U and X: The Guarantor is not engaged in the business
            of extending credit for the purpose of purchasing or carrying margin
            stock, and no proceeds of any Advances will be used for a purpose
            which violates, or would be inconsistent with, F.R.S. Board
            Regulation T, U or X. Terms for which meanings are provided in
            F.R.S. Board Regulation T, U or X or any regulations substituted
            therefor, as from time to time in effect, are used in this Clause
            3.1.12 with such meanings.

     3.1.13 Accuracy of Information: All factual information heretofore or
            contemporaneously furnished by the Guarantor in writing to the
            Facility Agent or any Bank for purposes of or in connection with
            this Guarantee or any transaction contemplated hereby is, and all
            other such written factual information hereafter furnished by the
            Guarantor in writing to the Facility Agent or any Bank will be, true
            and materially accurate in every material respect on the date as of
            which such information is dated or certified and as of the date of
            execution and delivery of this Guarantee by the Facility Agent and
            such information is not, or shall not be, as the case may be,
            incomplete by omitting to state any material fact necessary to make
            such information not materially misleading.

     3.1.14 The Obligations: The Obligations are senior, unsecured Indebtedness
            of the Guarantor ranking at least pari passu with all other senior,
            unsecured Indebtedness of the Guarantor.

--------------------------------------------------------------------------------

     3.1.15 Year 2000 Matters: The Guarantor has reviewed its operations and
            those of its Subsidiaries with a view to assessing whether its
            businesses or the businesses of any of its Subsidiaries will, in the
            receipt, transmission, processing, manipulation, storage, retrieval,
            retransmission or other utilisation of data, be vulnerable to a Year
            2000 Problem or will be vulnerable to the effects of a Year 2000
            Problem suffered by any of the Guarantor's or any of its
            Subsidiaries' major commercial counterparties. Based on such review
            the Guarantor has no reason to believe that a Material Adverse
            Effect will occur with respect to its businesses or operations or
            the businesses or operations of any of its Subsidiaries resulting
            from a Year 2000 Problem.

3.2  The representations and warranties set out in Clause 3.1 shall be deemed to
     be repeated on the date of drawdown of each Advance (unless stated to
     relate solely to an earlier date, in which case such representations and
     warranties shall be true and correct as of such earlier date). The
     representations and warranties set out in Clause 3.1.1 to 3.1.5 (inclusive)
     shall be deemed to be repeated by the Guarantor on the first day of each
     Interest Period with reference to the facts and circumstances then
     existing.

4    Covenants

4.1  Affirmative Covenants: The Guarantor agrees with the Facility Agent (on
     behalf of itself and each Bank) that, until the Total Commitments have
     terminated and all obligations of the Borrower under the Facility Agreement
     have been paid and performed in full, the Guarantor will perform the
     obligations set forth in this Clause 4.1.

     4.1.1  Financial Information, Reports, Notices: The Guarantor will furnish,
            or will cause to be furnished, to the Facility Agent copies of the

                   Guarantor and its Subsidiaries as of the end of such Fiscal

                   of the Guarantor and its Subsidiaries for such Fiscal Quarter

                   Fiscal Year and ending with the end of such Fiscal Quarter,
                   certified by an Authorised Representative with responsibility
                   for financial matters;

                   and its Subsidiaries, including therein consolidated balance
                   sheets of the Guarantor and its Subsidiaries as of the end of
                   such Fiscal Year and consolidated statements of income and
                   cash flows of the Guarantor and its Subsidiaries for such
                   Fiscal Year, and accompanied by the unqualified opinion of
                   Arthur Andersen & Co. or other internationally recognised
                   independent auditors selected by the Guarantor which report
                   shall state that such consolidated financial statements
                   present fairly in all material respects the financial
                   position for the periods

--------------------------------------------------------------------------------

                   indicated in conformity with US GAAP applied on a basis
                   consistent with prior periods;

            (iii)  concurrently with the delivery of the financial statements

                   calculations and computations in all respects satisfactory to
                   the Facility Agent) compliance with the financial covenant
                   set forth in Clause 4.2.3;

            (iv)   as soon as possible and in any event within 5 Business Days

                   occurrence of each Default, a statement of such Authorised
                   Representative setting forth details of such Default or
                   default and the action which the Guarantor has taken and
                   proposes to take with respect thereto;

            (v)    as soon as possible and in any event within 5 Business Days
                   after (1) the occurrence of any material adverse development
                   with respect to any litigation, action, proceeding, or labour
                   controversy of the type described in Clause 3.1.7 or (2) the
                   commencement of any labour controversy, litigation, action,

                   thereof and, upon request of the Facility Agent, copies of

            (vi)   promptly after the sending or filing thereof, copies of all
                   reports and registration statements which the Guarantor files
                   with the Securities and Exchange Commission or any national
                   securities exchange;

            (vii)  immediately upon becoming aware of the institution of any
                   steps by the Guarantor or any other Person to terminate any
                   Pension Plan (other than a standard termination under ERISA
                   Section 4041(b)), or the failure to make a required
                   contribution to any Pension Plan if such failure is
                   sufficient to give rise to a Lien under Section 302(f) of
                   ERISA, or the taking of any action with respect to a Pension
                   Plan which could result in the requirement that the Guarantor
                   furnish a bond or other security to the PBGC or such Pension
                   Plan, or the occurrence of any event with respect to any
                   Pension Plan which could result in the incurrence by the
                   Guarantor or any member of the Controlled Group of any
                   material liability (other than liabilities incurred in the
                   ordinary course of maintaining the Pension Plan), fine or
                   penalty, or any increase in the contingent liability of the
                   Guarantor with respect to any post-retirement Welfare Plan
                   benefit which has a Material Adverse Effect, notice thereof
                   and copies of all documentation relating thereto; and

            (viii) as soon as known, any changes in Guarantor's Debt Rating by
                   Moody's or S&P or any other rating agency which maintains a
                   Debt Rating on the Guarantor which is used in the Pricing
                   Grid.

     4.1.2  Compliance with Laws: The Guarantor will comply in all material
            respects with all applicable law, rules, regulations and orders,
            such compliance to include the

--------------------------------------------------------------------------------
<PAGE>

            payment, before the same become delinquent, of all taxes,
            assessments and governmental charges imposed upon it or upon its
            property (except to the extent such assignments and charges are
            being diligently contested in good faith by appropriate proceedings
            and for which adequate reserves in accordance with US GAAP shall
            have been set aside on its books).

     4.1.3  Maintenance of Properties: The Guarantor will, and will use
            reasonable efforts to cause each of its Subsidiaries and
            Partnerships to, maintain, preserve, protect and keep its property
            and equipment in good repair, working order and condition (ordinary
            wear and tear excepted), and make necessary and proper repairs,
            renewals and replacements so that its business carried on in
            connection therewith may be properly conducted at all times unless
            the Guarantor determines in good faith that the continued
            maintenance of any of its properties or equipment is no longer
            economically desirable and except where the failure so to do would
            not have a Material Adverse Effect.

     4.1.4  Insurance: The Guarantor will maintain or cause to be maintained
            with responsible insurance companies insurance with respect to its
            properties and business against such casualties and contingencies
            and of such types and in such amounts as is customary in the case of
            similar businesses.

     4.1.5  Books and Records: The Guarantor will, and will cause each of its
            active Subsidiaries to, keep books and records which accurately
            reflect all of its business affairs and transactions and permit the
            Facility Agent and each Bank or any of their respective
            representatives (at the Facility Agent's or such Bank's expense), at
            reasonable times and intervals upon reasonable prior notice, to
            visit all of its offices, to discuss its financial matters with its
            officers and independent public accountant. The Guarantor will at
            any reasonable time and from time to time upon reasonable prior
            notice, permit the Facility Agent and the Banks or any of their
            respective agents or representatives to examine and make copies of
            and abstracts from the records and books of account of the
            Guarantor; provided that by virtue of this Clause 4.1.5 the
            Guarantor shall not be deemed to have waived any right to
            confidential treatment of the information obtained, subject to the
            provisions of applicable law or court order.

     4.1.6  Environmental Covenant: The Guarantor will, and will use best
            efforts to cause each of its Subsidiaries and Partnerships to:

                   Hazardous Materials in material compliance with all
                   applicable Environmental Laws, in each case where the failure

                   Adverse Effect;

            (ii)   promptly cure and have dismissed to the reasonable
                   satisfaction of the Facility Agent any actions and

                   expected to have a Material Adverse Effect; provided that the
                   Guarantor or such Subsidiary or Partnership may postpone such
                   cure and dismissal during any period in which it is
                   diligently pursuing any available appeals in such action or
                   proceeding so long as such postponement would not be

                   obligations, leases and contracts (other than for borrowed

                   permitted thereby, provided that the Guarantor's Obligations
                   shall be equally and rateably secured with any and all such
                   Indebtedness and with any other Indebtedness similarly

            (vii)  any Lien existing on the property of the Guarantor on the
                   Effective Date.

            In the event that the Guarantor shall propose to create, incur,
            assume or suffer to exist any Lien upon any property at any time
            directly owned by it to secure any Indebtedness as contemplated by
            Clause 4.2.2(vi) above, the Guarantor will give prior written notice
            thereof to the Facility Agent, who shall give notice to the Banks,
            and the Guarantor will, prior to or simultaneously with the creation
            of such Lien, effectively secure the Guarantor's Obligations equally
            and rateably with such Indebtedness.

     4.2.3  Financial Condition: The Guarantor will not permit its Tangible Net
            Worth to be less than $400,000,000 plus 25% of the Guarantor's and

            quarter ending after 30 September 1992.

     4.2.4  Investments: The Guarantor will not, and will not permit any of its
            Subsidiaries to, make, incur, assume or suffer to exist any
            Investment in any other Person, except:

--------------------------------------------------------------------------------
<PAGE>

            (i)    Investments existing on the Effective Date;

            (ii)   Cash Equivalent Investments provided, however, that any
                   Investment which when made complies with the requirements of
                   the definition of the term "Cash Equivalent Investment" may
                   continue to be held notwithstanding that such Investment if
                   made thereafter would not comply with such requirements;

            (iii)  without duplication, Investments permitted as Indebtedness
                   pursuant to Clause 4.2.1;

            (iv)   otherwise in the ordinary course of business; and

            (v)    Investments permitted pursuant to Clause 4.2.5(ii).

     4.2.5  Consolidation Merger: The Guarantor will not, and will not permit
            any of its Subsidiaries to, liquidate or dissolve, consolidate with,
            or merge into or with, any other corporation, or purchase or
            otherwise acquire all or substantially all of the assets of any
            Person (or of any division thereof) except:

            (i)    any such Subsidiary may liquidate or dissolve voluntarily
                   into, and may merge with and into, the Guarantor or any other
                   Subsidiary, and the assets or stock of any Subsidiary may be
                   purchased or otherwise acquired by the Guarantor or any other
                   Subsidiary;

            (ii)   so long as no Default (by reason of the violation of Clause
                   4.2.3) has occurred and is continuing or would occur after
                   giving effect thereto, the Guarantor or any of its
                   Subsidiaries may purchase all or substantially all of the
                   assets of any Person, or (in the case of any such Subsidiary)
                   acquire such person by merger; and

            (iii)  provided that no Default has occurred and is continuing or
                   would occur after giving effect thereto (including, without
                   limitation, a Change in Control), the Guarantor may
                   consolidate with or merge into any other Person, or convey,
                   transfer or lease its properties and assets substantially as
                   an entirety to any person, or permit any Person to merge into
                   or consolidate with the Guarantor if the Guarantor is the
                   surviving corporation or the surviving corporation or
                   purchaser or lessee is a corporation incorporated under the
                   laws of the United States of America or Canada and assumes
                   the Guarantor's Obligations.

     4.2.6  Asset Dispositions: The Guarantor will not, and will not permit any
            of its Subsidiaries to, sell, transfer, lease, contribute or

            respect to, all or any substantial part of its assets (including
            accounts receivable and capital stock of Subsidiaries) to any
            Person, unless:

            (i)    such sale, transfer, lease, contribution or conveyance is the
                   ordinary course of its business; or

            (ii)   the net book value of such assets, together with the net book
                   value of all other assets sold, transferred, leased,
                   contributed or conveyed otherwise

--------------------------------------------------------------------------------
<PAGE>

                   than in the ordinary course of business by the Guarantor or
                   any of its Subsidiaries pursuant to this Clause 4.2.6(ii)
                   during the most recent 12 month period since the Effective
                   Date, does not exceed 10% of Net Tangible Assets computed as
                   of the end of the most recent quarter preceding such sale;
                   provided, however, that any such sales shall be disregarded
                   for purposes of the limitation of this Clause 4.2.6(ii) if
                   the proceeds are invested in assets in similar or related
                   lines of business of the Guarantor, and provided further,
                   that the Guarantor may sell or otherwise dispose of assets in
                   excess of such 10% if the proceeds from such sales or
                   dispositions, which are not so reinvested, are retained by
                   the Guarantor as cash or Cash Equivalent Investments.

     4.2.7  Transactions with Affiliates: The Guarantor will not enter into, or
            cause, suffer or permit to exist any arrangement or contract with
            any of its Affiliates unless such arrangement or contract is fair
            and equitable to the Guarantor and is an arrangement or contract of
            the kind which would be entered into by a prudent Person in the
            position of the Guarantor with a Person which is not one of its
            Affiliates.

     4.2.8  Restrictive Agreements: The Guarantor will not, and will not permit
            any of its Subsidiaries to, enter into any agreement (excluding any
            Loan Document and any agreement governing any Indebtedness permitted
            by Clause 4.2.1(ii) as to the assets financed with the proceeds of
            such Indebtedness) prohibiting:

            (i)    the ability of the Guarantor to amend or otherwise modify any
                   Loan Document; or

            (ii)   the ability of any Subsidiary to make any payments, directly
                   or indirectly, to the Guarantor by way of dividend, advances,
                   repayments of loans or advances, reimbursements of management
                   and other intercompany charges, expenses and accruals or
                   other returns on investments, or any other agreement or
                   arrangement which restricts the ability of any such
                   Subsidiary to make any payment, directly or indirectly, to
                   the Guarantor where such prohibition or restriction has a
                   Material Adverse Effect.

4.3  ERISA: The Guarantor will not engage in any prohibited transactions under
     Section 406 of ERISA or under Section 4975 of the Internal Revenue Code,
     which would subject the Guarantor to any tax, penalty or other liabilities
     having a Material Adverse Effect.

5    Invalidity

     If any provision of this Guarantee is held to be invalid or unenforceable,
     then such provision shall (so far as it is invalid or unenforceable) be
     given no effect and shall be deemed not to be included in this Guarantee
     but without invalidating any of the remaining provisions of this Guarantee.
     The parties shall then use all reasonable endeavours to replace the invalid
     or unenforceable provision with a valid provision the effect of which is as
     close as possible to the intended effect of the invalid or unenforceable
     provision.
