ARTICLE 3

ENFORCEMENT

 

Section 3.1                Remedies.

 

None of the Secured Creditors nor the Trustee on behalf of the Secured
Creditors is bound to exhaust its recourse against any Issuer or any other
Person or realize on any security it may hold in respect of the Note
Obligations before being entitled to (i) enforce payment and performance
under this Guarantee or (ii) pursue any other remedy against the
Guarantor, and the Guarantor renounces all benefits of discussion and division.

 

Section 3.2                Amount of Note Obligations.

 

Any account settled or stated by or between the Trustee and the
Issuers, or if any such account has not been settled or stated immediately
before demand for payment under this Guarantee, any account stated by the
Trustee shall, in the absence of manifest mathematical error, be accepted by
the Guarantor as presumptively correct evidence of the amount of the Note
Obligations which is due by the Issuers to the Secured Creditors or remains
unpaid by the Issuers to the Secured Creditors.

 

Section 3.3                Payment on Demand.

 

The Guarantor will pay and perform the Note Obligations and pay all
other amounts payable by it to the Secured Creditors or the Trustee on behalf
of the Secured Creditors under this Guarantee, and the obligation to do so
arises, immediately after demand for such payment or performance is made in
writing to it.  The liability of the
Guarantor bears interest from the date of such demand at the rate or rates of
interest then applicable to the Note Obligations under and calculated in the
manner provided in the Indenture Documents (including any adjustment to give
effect to the provisions of the Interest Act (Canada)).

 

7

 

Section 3.4                Suspension of Guarantor Rights.

 

So long as there are any Note Obligations, the Guarantor will not
exercise any rights which it may at any time have by reason of the performance
of any of its obligations under this Guarantee (i) to be indemnified by
any Issuer, (ii) to claim contribution from any other guarantor of the
debts, liabilities or obligations of any Issuer, or (iii) subject to Section 3.6,
to take the benefit (in whole or in part and whether by way of subrogation or
otherwise) of any rights of the Secured Creditors or the Trustee under any of
the Indenture Documents.

 

Section 3.5                No Prejudice to Secured Creditors or Trustee.

 

None of the Secured Creditors nor the Trustee on behalf of the Secured
Creditors are prejudiced in any way in the right to enforce any provision of
this Guarantee by any act or failure to act on the part of the Issuers, the
Secured Creditors or the Trustee on behalf of the Secured Creditors.  The Trustee and the other Secured Creditors
may, at any time and from time to time, in such manner as any of them may
determine is expedient, without any consent of, or notice to, the Guarantor and
without impairing or releasing the obligations of the Guarantor (i) change
the manner, place, time or terms of payment or performance of the Note
Obligations, (ii) renew or alter the Note Obligations, (iii) amend,
vary, modify, supplement or replace any Indenture Document or any other related
document or instrument, (iv) discontinue, reduce, renew, increase, abstain
from renewing or otherwise vary any credit or credit facilities to, any
transaction with, any Issuer or any other Person, (v) release, compound or
vary the liability of any Issuer or any other Person liable in any manner under
or in respect of the Note Obligations, (vi) take or abstain from taking
securities or collateral from any other Person, or from perfecting securities
or collateral of any other Person, (vii) exercise or enforce or refrain
from exercising or enforcing any right or security against any Issuer, the
Guarantor or any other Person, (viii) accept compromises or arrangement
from any Person, (ix) apply any sums from time to time received to the
Note Obligations, or any part thereof, and change any such application in whole
or in part from time to time, (x) otherwise deal with, or waive or modify
their right to deal with, any Person and security, in each case, in accordance
with the Indenture Documents, if applicable. 
In their dealings with the Issuers, the Trustee and the other Secured
Creditors need not enquire into the authority or power of any Person purporting
to act for or on behalf of the Issuers.

 

Section 3.6                Rights of Subrogation.

 

Any rights of subrogation acquired by the Guarantor by reason of
payment under this Guarantee shall not be exercised until the Note Obligations
(other than contingent indemnity obligations)  have
been paid or repaid in full and such rights of subrogation shall be no greater
than the rights held by the Trustee and the other Secured Creditors.  In the event (i) of the liquidation, winding
up or bankruptcy of any Credit Party (whether voluntary or compulsory), (ii) that
any Credit Party makes a bulk sale of any of its assets within the provisions
of any bulk sales legislation, or (iii) that any Credit Party makes any
composition with creditors or enters into any scheme of arrangement, the
Trustee and the other Secured Creditors have the right to rank in priority to
the Guarantor for their full claims in respect of the Note Obligations and
receive all dividends and other payments until their claims have been paid in
full.  The Guarantor will continue to be
liable, less any payments made by it, for any balance which may be owing to the
Secured Creditors by the Issuers.  No
valuation or retention of their security by the Secured Creditors or the
Trustee 

 

8

 

on behalf of the Secured Creditors shall, as between any Credit Party,
the Trustee and the other Secured Creditors and the Guarantor, be considered as
a purchase of such security or as payment or satisfaction or reduction of all
or any part of the Note Obligations.  If
any amount is paid to the Guarantor in violation of this Section at any
time when all the Note Obligations (other than contingent indemnity
obligations) have not been paid in full, the amount will be held in trust for
the benefit of the Trustee on behalf of the Secured Creditors and immediately
paid to the Trustee to be credited and applied to the Note Obligations, whether
matured or unmatured.  The Guarantor does
not have any recourse against any Secured Creditor for any invalidity,
non-perfection or unenforceability of any security held by the Secured
Creditors or the Trustee on behalf of the Secured Creditors or any irregularity
or defect in the manner or procedure by which the Secured Creditors or the
Trustee realize on such security.

 

Section 3.7                No Set-off.

 

To the fullest extent permitted by law, the Guarantor makes all
payments under this Guarantee without regard to any defence, counter-claim or
right of set-off available to it.

 

Section 3.8                Successors of the Issuers.

 

This Guarantee will not be revoked by any change in the constitution of
any Credit Party.

 

Section 3.9                Continuing Guarantee and Continuing Note Obligations.

 

The obligation of the Guarantor under Section 2.1 is a continuing
guarantee, and the obligation of the Guarantor under Section 2.2 is a
continuing obligation.  Each of Section 2.1
and Section 2.2 extends to all present and future Note Obligations,
applies to and secures the ultimate balance of the Note Obligations due or
remaining due to the Trustee and the other Secured Creditors (other than
contingent indemnity obligations)  and is binding
as a continuing obligation of the Guarantor until the Trustee on behalf of the
Secured Creditors releases the Guarantor, or until payment in full of the Note
Obligations (other than contingent indemnity obligations).  This Guarantee will continue to be effective
or be reinstated, as the case may be, if at any time any payment of any of the
Note Obligations is rescinded or must otherwise be returned by any Secured
Creditors upon the insolvency, bankruptcy or reorganization of any Issuer or
otherwise, all as though the payment had not been made.

 

Section 3.10             Supplemental Security.

 

This Guarantee is in addition and without prejudice to and supplemental
to all other guarantees, indemnities, obligations and security now held or
which may hereafter be held by any Secured Creditor or the Trustee on behalf of
the Secured Creditors.

 

Section 3.11             Security for Guarantee.

 

The Guarantor acknowledges that this Guarantee is intended to secure
payment and performance of the Note Obligations and that the payment and
performance of the Note Obligations and the other obligations of the Guarantor
under this Guarantee are secured pursuant to the terms and provisions of the
Guarantor Security Documents.

 

9

 

Section 3.12             Interest Act (Canada).

 

The Guarantor acknowledges that certain of the rates of interest
applicable to the Note Obligations may be computed on the basis of a year of
360 days or 365 days, as the case may be and paid for the actual number of days
elapsed.  For purposes of the Interest Act
(Canada), whenever any interest is calculated using a rate based on a year of
360 days or 365 days, as the case may be, such rate determined pursuant to such
calculation, when expressed as an annual rate is equivalent to (i) the
applicable rate based on a year of 360 days or 365 days, as the case may be, (ii) multiplied
by the actual number of days in the calendar year in which the period for such
interest is payable (or compounded) ends, and (iii) divided by 360 or 365,
as the case may be.

 

Section 3.13             Taxes.

 

(1)           All payments made by the Guarantor under this
Guarantee or under any of the Guarantor Security Documents will be made free
and clear of and without withholding or deduction for or on account of any
present or future Taxes imposed or levied by or on behalf of any Taxing
Authority in the Relevant Taxing Jurisdiction, unless the Guarantor is required
to withhold or deduct Taxes by law or by the interpretation or administration
thereof.  If the Guarantor is required to
withhold or deduct any amount for or on account of Taxes imposed by a Relevant
Taxing Jurisdiction, from any payment made under or with respect to this
Guarantee or under any of the Guarantor Security Documents, the Guarantor will
pay as additional interest the Additional Amounts as may be necessary so that
the net amount received by each Noteholder (including Additional Amounts) after
such withholding or deduction will equal the amount the Noteholder would have received
if such Taxes had not been withheld or deducted; provided, however, that no
Additional Amounts will be payable with respect to any Tax that would not have
been imposed, payable or due:

 

(a)                                  but for the Noteholder or
beneficial owner of Notes not dealing at arm’s length with the Guarantor (for
purposes of the Income Tax Act (Canada)) at the
time of the making of such payment;

 

(b)                                 but for the existence of any present
or former connection between the Noteholder (or the beneficial owner of, or
person ultimately entitled to obtain an interest in, such Notes, including a
fiduciary, settler, beneficiary, member, partner, shareholder or other equity
interest owner of, or possessor of power over, such Noteholder or beneficial
owner, if such Noteholder or beneficial owner is an estate, trust, partnership,
limited liability company, corporation or other entity) and the Relevant Taxing
Jurisdiction (including being a citizen or resident or national of, or carrying
on a business or maintaining a permanent establishment in, or being physically
present in, the Relevant Taxing Jurisdiction) other than the mere holding of
the Notes or enforcement of rights thereunder or the receipt of payments in
respect thereof; or

 

(c)                                  but for the failure by the
Noteholder to satisfy any certification, identification, information,
documentation or other reporting requirements concerning the nationality,
residence, identity or connection with the 

 

10

 

Relevant Taxing Jurisdiction or arm’s-length relationship with the
Guarantor of the Holder or beneficial owner or otherwise establishing the right
to the benefit of an exemption from, or reduction in the rate of, withholding
or deduction, if (a) such compliance is required by law, regulation,
administrative practice or an applicable treaty of the Relevant Taxing
Jurisdiction as a precondition to exemption from, or a reduction in the rate of
deduction of withholding of, such Taxes and (b) the Guarantor have
provided the Trustee with thirty (30) days’ prior written notice of such requirement.

 

(2)           Additional Amounts will not be payable if the
beneficial owner of, or person ultimately entitled to obtain an interest in,
such Notes is not the sole beneficial owner of such payments, or is a fiduciary
or partnership (including any entity or arrangement treated as a partnership by
the Relevant Taxing Jurisdiction), to the extent that any beneficial owner,
beneficiary or settler with respect to such fiduciary or any partner or member
of such partnership would not have been entitled to such Additional Amounts
with respect to such payments had such beneficial owner, beneficiary, settler,
partner or member received directly its beneficial or distributive shares of
such payments.  In addition, Additional
Amounts will not be payable with respect to (i) any Tax which is payable
otherwise than by withholding from payments of, or in respect of principal of,
or any interest on, the Notes, this Guarantee or any of the Guarantor Security
Documents, (ii) any withholding or deduction that relates to any estate,
inheritance, gift or similar tax, duty, assessment or governmental charge, (iii) any
withholding or deduction imposed on a payment to an individual and required to
be made pursuant to European Union Directive on the taxation of savings income
which was adopted by the ECOFIN Council (the Council of EU Finance and Economic
Ministers), or any law implementing or complying with, or introduced to conform
to, such directive, or pursuant to related measures entered into on a
reciprocal basis between member states of the European Union and certain
non-European Union countries and dependent or associated territories and (iv) any
Tax imposed or levied by, or on behalf of, the United States of America or any
State or other political subdivision thereof.

 

(3)           Whenever in this Guarantee or any of the
Guarantor Security Documents there is mentioned, in any context, the payment of
Note Obligations or other amounts based upon the principal amount of the Notes
or of principal, interest or of any other amount payable under or with respect
to any of the Notes, such mention shall be deemed to include mention of the
payment of Additional Amounts to the extent that, in such context, Additional
Amounts are, were or would be payable in respect thereof.

 

(4)           Upon request, the Guarantor will provide the
Trustee with documentation satisfactory to the Trustee evidencing the payment
of Additional Amounts.

 

(5)           The Guarantor will pay any present or future
stamp, court or documentary taxes, or any other excise or property taxes,
charges or similar levies which arise in a Relevant Taxing Jurisdiction from
the execution, delivery or registration of the Notes, this 

 

11

 

Guarantee or under any of the Guarantor Security Documents and any such
taxes, charges or similar levies imposed by any jurisdiction resulting from, or
required to be paid in connection with the enforcement of the Notes, this
Guarantee or under any of the Guarantor Security Documents or any other such
document or instrument following the occurrence of any Event of Default with
respect to the Notes.

 

(6)           The provisions of this Section 3.13
survive the termination of this Guarantee.

 

Section 3.14             Judgment Currency.

 

(1)           If for the purposes of obtaining judgment in
any court it is necessary to convert all or any part of the Note Obligations or
any other amount due to a Secured Creditor in respect of the Guarantor’s
obligations under this Guarantee in any currency (the “Original
Currency”) into another currency (the “Other
Currency”), the Guarantor, to the fullest extent that it may
effectively do so, agrees that the rate of exchange used shall be that at
which, in accordance with normal banking procedures, the Secured Creditor could
purchase the Original Currency with the Other Currency on the Business Day
preceding that on which final judgment is paid or satisfied.

 

(2)           The obligations of the Guarantor in respect
of any sum due in the Original Currency from it to any Secured Creditor shall,
notwithstanding any judgment in any Other Currency, be discharged only to the
extent that on the Business Day following receipt by such Secured Creditor of
any sum adjudged to be so due in such Other Currency such Secured Creditor may,
in accordance with its normal banking procedures, purchase the Original
Currency with such Other Currency.  If
the amount of the Original Currency so purchased is less than the sum originally
due to the Secured Creditor in the Original Currency, the Guarantor agrees, as
a separate obligation and notwithstanding any such judgment, to indemnify the
Secured Creditor against such loss, and if the amount of the Original Currency
so purchased exceeds the sum originally due to the Secured Creditor in the
Original Currency, the Secured Creditor agrees to remit such excess to the
Guarantor.

 

ARTICLE 4

GENERAL

 

Section 4.1                Notices, etc.

 

Any notices, directions or other communications provided for in this
Guarantee must be in writing and given in accordance with the Indenture.

 

Section 4.2                No Merger, Survival of Representations and Warranties.

 

The covenants of the Guarantor in this Guarantee survive the execution
and delivery of this Guarantee and the issuance of Notes under the
Indenture.  Notwithstanding any
investigation made by or on behalf of the Trustee or the other Secured
Creditors, the covenants in this Guarantee continue in full force and effect.

 

Section 4.3                Further Assurances.

 

(1)           The Guarantor will do all acts and things and
execute and deliver, or cause to be executed and delivered, all documents and
instruments that the Trustee may 

 

12

 

reasonably request to give full effect to this Guarantee and to perfect
and preserve the rights and powers of the Trustee and the other Secured
Creditors under this Guarantee, including any acknowledgements and
confirmations of this Guarantee and the Guarantor Security Documents.

 

(2)           The Guarantor acknowledges and confirms that
the Guarantor itself has established its own adequate means of obtaining from
each Issuer on a continuing basis all information desired by the Guarantor
concerning the financial condition of such Issuer and that the Guarantor will look
to such Issuer and not to the Trustee or the other Secured Creditors, in order
for the Guarantor to keep adequately informed of changes in such Issuer’s
financial condition.

 

Section 4.4                Successors and Assigns.

 

This Guarantee is binding upon the Guarantor, its successors and
assigns, and enures to the benefit of each of the Secured Creditors and each of
their respective successors permitted transferees and permitted assigns.  No other Person (including any other creditor
of the Guarantor) shall have any interest herein or any right or benefit with
respect hereto.  Without limiting the
generality of the foregoing, any Secured Creditor may assign or otherwise
transfer any indebtedness held by it secured by this Guarantee to any other
Person, and such other Person shall thereupon become vested with all the
benefits in respect thereof granted to such Secured Creditor, herein or
otherwise.  The Guarantor may not assign,
transfer or delegate any of its rights or obligations under this Guarantee
without the prior written consent of the Trustee which may be unreasonably
withheld, except pursuant to transactions permitted under the Indenture.

 

Section 4.5                Amendment.

 

This Guarantee may only be amended, supplemented or otherwise modified
by written agreement executed by the Trustee and the Guarantor.

 

Section 4.6                Waivers, etc.

 

(1)           No consent or waiver by the Trustee or the
other Secured Creditors in respect of this Guarantee is binding unless made in
writing and signed by an authorized officer of the Trustee.  Any consent or waiver given under this
Guarantee is effective only in the specific instance and for the specific
purpose for which given.  No waiver of
any of the provisions of this Guarantee constitutes a waiver of any other
provision.

 

(2)           A failure or delay on the part of the Trustee
or any other Secured Creditor in exercising a right under this Guarantee does
not operate as a waiver of, or impair, any right of the Trustee or such other
Secured Creditor however arising.  A
single or partial exercise of a right on the part of the Trustee or the other
Secured Creditors does not preclude any other or further exercise of that right
or the exercise of any other right by the Trustee or such other Secured
Creditors.

 

Section 4.7                Severability.

 

If any court of competent jurisdiction from which no appeal exists or
is taken, determines that any provision of this Guarantee is illegal, invalid
or unenforceable, that 

 

13

 

provision will be severed from this Guarantee and the remaining
provisions will remain in full force and effect.

 

Section 4.8                Enforcement.

 

The Trustee on behalf of the Secured Creditors agrees that the
enforcement of this Guarantee is subject to the terms of the Indenture,
including Section 6.06 thereof.

 

Section 4.9                Application of Proceeds.

 

All monies collected by the Trustee or any other Secured Creditor under
this Guarantee will be applied as provided in the Indenture.  To the extent any other Indenture Document
requires proceeds of collateral under such Indenture Document to be applied in
accordance with the provisions of this Guarantee, the Trustee or holder under
such other Indenture Document shall apply such proceeds in accordance with this
Section.

 

Section 4.10             Governing Law.

 

(1)           This Guarantee will be governed by,
interpreted and enforced in accordance with the laws of the Province of Alberta
and the federal laws of Canada applicable therein.

 

(2)           The Guarantor irrevocably attorns and submits
to the exclusive jurisdiction of any court of competent jurisdiction of the
Province of Alberta sitting in Calgary, Alberta in any action or proceeding
arising out of or relating to this Guarantee and the other Indenture Documents
to which it is a party.  The Guarantor irrevocably
waives objection to the venue of any action or proceeding in such court or that
such court provides an inconvenient forum. 
Nothing in this Section limits the right of the Trustee to bring
proceedings against the Guarantor in the courts of any other jurisdiction.

 

(3)           The Guarantor hereby irrevocably
consents to the service of any and all process in any such action or proceeding
by the delivery of copies of such process to the Guarantor at the address set
forth in Section 4.1 hereof.  Nothing in this Section affects the right of
the Trustee to serve process in any manner permitted by law.

 

Section 4.11             General Limitation on Guarantee Obligations

 

In any action or proceeding involving any state corporate limited
partnership or limited liability company law, or any applicable state, federal
or foreign bankruptcy, insolvency, reorganization or other law affecting the
rights of creditors generally, if the obligations of the Guarantor under Article 2
would otherwise be held or determined to be void, voidable, invalid or
unenforceable, or subordinated to the claims of any other creditors, on account
of the amount of its liability under Article 2, then, notwithstanding any
other provision to the contrary, the amount of such liability shall, without
any further action by the Guarantor, any Credit Party or any other person, be
automatically limited and reduced to the highest amount (after giving effect to
any right of contribution established hereunder) that is valid and enforceable
and not subordinated to the claims of other creditors as determined in such
action or proceeding.

 

14

 

Section 4.12             Release of the Guarantor.

 

The Guarantor shall be released from its obligations under this
Guarantee and its obligations under the other Indenture Documents upon payment
in full of the principal of, and accrued and unpaid interest and premium, if
any, and Additional Interest, if any, on the Notes and payment in full of all
other Note Obligations with respect to such Notes that are due and payable at
or prior to the time such principal, accrued and unpaid interest and premium
are paid.

 

Section 4.13             Business Corporations Act

 

To the extent required pursuant to Section 45 of the Business Corporations Act (Alberta), the Guarantor hereby
consents to the entering into of the transactions contemplated in the Indenture
and in this Guarantee (including the giving of guarantees and the granting of
security) by each of the other Credit Parties.

ENFORCEMENT

 

Section 3.1                                               Remedies.

 

None of the Secured Creditors nor the Trustee
on behalf of the Secured Creditors is bound to exhaust its recourse against any
Issuer or any other Person or realize on any security it may hold in respect of
the Note Obligations before being entitled to (i) enforce payment and
performance under this Guarantee or (ii) pursue any other remedy against
each of the Guarantors, and each of the Guarantors renounces all benefits of
discussion and division.

 

Section 3.2                                               Amount of Note Obligations.

 

Any account settled or stated by or between the
Trustee and the Issuers, or if any such account has not been settled or stated
immediately before demand for payment under this Guarantee, any account stated
by the Trustee shall, in the absence of manifest mathematical error, be
accepted by the Guarantors as presumptively correct evidence of the amount of
the Note Obligations which is due by the Issuers to the Secured Creditors or
remains unpaid by the Issuers to the Secured Creditors.

 

Section 3.3                                               Payment on Demand.

 

Each of the Guarantors will pay and perform the
Note Obligations and pay all other amounts payable by it to the Secured
Creditors or the Trustee on behalf of the Secured Creditors under this
Guarantee, and the obligation to do so arises, immediately after demand for
such payment or performance is made in writing to it.  The liability of each of the Guarantors bears
interest from the date of such demand at the rate or rates of interest then
applicable to the Note Obligations under and calculated in the manner provided
in the Indenture Documents (including any adjustment to give effect to the
provisions of the Interest Act (Canada)).

 

Section 3.4                                               Suspension of Guarantor Rights.

 

So long as there are any Note Obligations, no
Guarantor will exercise any rights which it may at any time have by reason of
the performance of any of its obligations under 

 

8

 

this Guarantee (i) to
be indemnified by any Issuer, (ii) to claim contribution from any other
guarantor of the debts, liabilities or obligations of any Issuer, or (iii) subject
to Section 3.6, to take the benefit (in whole or in part and whether by
way of subrogation or otherwise) of any rights of the Secured Creditors or the
Trustee under any of the Indenture Documents.

 

Section 3.5                                               No Prejudice to Secured Creditors or Trustee.

 

None of the Secured Creditors nor the Trustee
on behalf of the Secured Creditors are prejudiced in any way in the right to
enforce any provision of this Guarantee by any act or failure to act on the
part of the Issuers, the Secured Creditors or the Trustee on behalf of the
Secured Creditors.  The Trustee and the
other Secured Creditors may, at any time and from time to time, in such manner
as any of them may determine is expedient, without any consent of, or notice
to, any of the Guarantors and without impairing or releasing the obligations of
any of the Guarantors (i) change the manner, place, time or terms of
payment or performance of the Note Obligations, (ii) renew or alter the
Note Obligations, (iii) amend, vary, modify, supplement or replace any
Indenture Document or any other related document or instrument, (iv) discontinue,
reduce, renew, increase, abstain from renewing or otherwise vary any credit or
credit facilities to, any transaction with, any Issuer or any other Person, (v) release,
compound or vary the liability of any Issuer or any other Person liable in any
manner under or in respect of the Note Obligations, (vi) take or abstain
from taking securities or collateral from any other Person, or from perfecting
securities or collateral of any other Person, (vii) exercise or enforce or
refrain from exercising or enforcing any right or security against any Issuer,
any Guarantor or any other Person, (viii) accept compromises or
arrangement from any Person, (ix) apply any sums from time to time
received to the Note Obligations, or any part thereof, and change any such
application in whole or in part from time to time, (x) otherwise deal
with, or waive or modify their right to deal with, any Person and security, in
each case, in accordance with the Indenture Documents, if applicable.  In their dealings with the Issuers, the
Trustee and the other Secured Creditors need not enquire into the authority or
power of any Person purporting to act for or on behalf of the Issuers.

 

Section 3.6                                               Rights of Subrogation.

 

Any rights of subrogation acquired by any
Guarantor by reason of payment under this Guarantee shall not be exercised
until the Note Obligations (other than contingent indemnity obligations)  have been paid or repaid in full and such rights of
subrogation shall be no greater than the rights held by the Trustee and the
other Secured Creditors.  In the event (i) of
the liquidation, winding up or bankruptcy of any Credit Party (whether
voluntary or compulsory), (ii) that any Credit Party makes a bulk sale of
any of its assets within the provisions of any bulk sales legislation, or (iii) that
any Credit Party makes any composition with creditors or enters into any scheme
of arrangement, the Trustee and the other Secured Creditors have the right to
rank in priority to each of the Guarantors for their full claims in respect of
the Note Obligations and receive all dividends and other payments until their
claims have been paid in full.  Each of
the Guarantors will continue to be liable, less any payments made by it, for
any balance which may be owing to the Secured Creditors by the Issuers.  No valuation or retention of their security
by the Secured Creditors or the Trustee on behalf of the Secured Creditors
shall, as between any Credit Party, the Trustee and the other Secured Creditors
and the Guarantors, be considered as a purchase of such security or as payment
or satisfaction or reduction of all or any part of the Note Obligations.  If any amount is paid to any Guarantor in
violation of this Section at any time when all the 

 

9

 

Note Obligations
(other than contingent indemnity obligations) have not been paid in full, the
amount will be held in trust for the benefit of the Trustee on behalf of the
Secured Creditors and immediately paid to the Trustee to be credited and
applied to the Note Obligations, whether matured or unmatured.  No Guarantor has any recourse against any
Secured Creditor for any invalidity, non-perfection or unenforceability of any
security held by the Secured Creditors or the Trustee on behalf of the Secured
Creditors or any irregularity or defect in the manner or procedure by which the
Secured Creditors or the Trustee realize on such security.

 

Section 3.7                                               No Set-off.

 

To the fullest extent permitted by law, each of
the Guarantors makes all payments under this Guarantee without regard to any
defence, counter-claim or right of set-off available to it.

 

Section 3.8                                               Successors of the Issuers.

applies to and secures the ultimate balance of the Note Obligations due or
remaining due to the Trustee and the other Secured Creditors (other than
contingent indemnity obligations)  and is binding
as a continuing obligation of each Guarantor until the Trustee on behalf of the
Secured Creditors releases such Guarantor, or until payment in full of the Note
Obligations (other than contingent indemnity obligations).  This Guarantee will continue to be effective
or be reinstated, as the case may be, if at any time any payment of any of the
Note Obligations is rescinded or must otherwise be returned by any Secured
Creditors upon the insolvency, bankruptcy or reorganization of any Issuer or
otherwise, all as though the payment had not been made.

 

Section 3.10                                        Supplemental Security.

 

This Guarantee is in addition and without
prejudice to and supplemental to all other guarantees, indemnities, obligations
and security now held or which may hereafter be held by any Secured Creditor or
the Trustee on behalf of the Secured Creditors.

 

Section 3.11                                        Security for Guarantee.

 

Each of the Guarantors acknowledges that this
Guarantee is intended to secure payment and performance of the Note Obligations
and that the payment and performance of the Note Obligations and the other
obligations of the Guarantors under this Guarantee are secured pursuant to the
terms and provisions of the Guarantor Security Documents.

 

Section 3.12                                        Interest Act (Canada).

 

Each of the Guarantors acknowledges that
certain of the rates of interest applicable to the Note Obligations may be
computed on the basis of a year of 360 days or 365 days, as 

 

10

 

the case may be and
paid for the actual number of days elapsed. 
For purposes of the Interest Act (Canada), whenever any interest is calculated
using a rate based on a year of 360 days or 365 days, as the case may be, such
rate determined pursuant to such calculation, when expressed as an annual rate
is equivalent to (i) the applicable rate based on a year of 360 days or
365 days, as the case may be, (ii) multiplied by the actual number of days
in the calendar year in which the period for such interest is payable (or
compounded) ends, and (iii) divided by 360 or 365, as the case may be.

 

Section 3.13                                        Taxes.

 

(1)                                  All payments made by the Guarantors under this Guarantee or under any of
the Guarantor Security Documents will be made free and clear of and without
withholding or deduction for or on account of any present or future Taxes imposed
or levied by or on behalf of any Taxing Authority in the Relevant Taxing
Jurisdiction, unless a Guarantor is required to withhold or deduct Taxes by law
or by the interpretation or administration thereof.  If a Guarantor is required to withhold or
deduct any amount for or on account of Taxes imposed by a Relevant Taxing
Jurisdiction, from any payment made under or with respect to this Guarantee or
under any of the Guarantor Security Documents, such Guarantor will pay as
additional interest the Additional Amounts as may be necessary so that the net
amount received by each Noteholder (including Additional Amounts) after such
withholding or deduction will equal the amount the Noteholder would have received
if such Taxes had not been withheld or deducted; provided, however, that no
Additional Amounts will be payable with respect to any Tax that would not have
been imposed, payable or due:

 

(a)                                  but for the Noteholder or beneficial owner of Notes not dealing at arm’s
length with the Guarantors (for purposes of the Income Tax
Act (Canada)) at the time of the making of such payment;

 

(b)                                 but for the existence of any present or former connection between the
Noteholder (or the beneficial owner of, or person ultimately entitled to obtain
an interest in, such Notes, including a fiduciary, settler, beneficiary,
member, partner, shareholder or other equity interest owner of, or possessor of
power over, such Noteholder or beneficial owner, if such Noteholder or
beneficial owner is an estate, trust, partnership, limited liability company,
corporation or other entity) and the Relevant Taxing Jurisdiction (including being
a citizen or resident or national of, or carrying on a business or maintaining
a permanent establishment in, or being physically present in, the Relevant Taxing
Jurisdiction) other than the mere holding of the Notes or enforcement of rights
thereunder or the receipt of payments in respect thereof; or

 

(c)                                  but for the failure by the Noteholder to satisfy any certification,
identification, information, documentation or other reporting requirements
concerning the nationality, residence, identity or connection with the Relevant
Taxing Jurisdiction or arm’s-length relationship with the Guarantors of the
Holder or beneficial owner or otherwise establishing the right to the benefit
of an exemption from, or reduction in the rate of,

 

11

 

withholding or
deduction, if (a) such compliance is required by law, regulation,
administrative practice or an applicable treaty of the Relevant Taxing
Jurisdiction as a precondition to exemption from, or a reduction in the rate of
deduction of withholding of, such Taxes and (b) the Guarantors have
provided the Trustee with thirty (30) days’ prior written notice of such requirement.

 

(2)                                  Additional Amounts will not be payable if the beneficial owner of, or
person ultimately entitled to obtain an interest in, such Notes is not the sole
beneficial owner of such payments, or is a fiduciary or partnership (including
any entity or arrangement treated as a partnership by the Relevant Taxing
Jurisdiction), to the extent that any beneficial owner, beneficiary or settler
with respect to such fiduciary or any partner or member of such partnership
would not have been entitled to such Additional Amounts with respect to such
payments had such beneficial owner, beneficiary, settler, partner or member
received directly its beneficial or distributive shares of such payments.  In addition, Additional Amounts will not be
payable with respect to (i) any Tax which is payable otherwise than by
withholding from payments of, or in respect of principal of, or any interest
on, the Notes, this Guarantee or any of the Guarantor Security Documents (ii) any
withholding or deduction that relates to any estate, inheritance, gift or
similar tax, duty, assessment or governmental charge, (iii) any withholding
or deduction imposed on a payment to an individual and required to be made
pursuant to European Union Directive on the taxation of savings income which
was adopted by the ECOFIN Council (the Council of EU Finance and Economic
Ministers), or any law implementing or complying with, or introduced to conform
to, such directive, or pursuant to related measures entered into on a
reciprocal basis between member states of the European Union and certain
non-European Union countries and dependent or associated territories, and (iv) any
Tax imposed or levied by, or on behalf of, the United States of America or any
State or other political subdivision thereof.

 

(3)                                  Whenever in this Guarantee or any of the Guarantor Security Documents
there is mentioned, in any context, the payment of Note Obligations or other
amounts based upon the principal amount of the Notes or of principal, interest
or of any other amount payable under or with respect to any of the Notes, such
mention shall be deemed to include mention of the payment of Additional Amounts
to the extent that, in such context, Additional Amounts are, were or would be
payable in respect thereof.

 

(4)                                  Upon request, the Guarantors will provide the Trustee with documentation
satisfactory to the Trustee evidencing the payment of Additional Amounts.

 

(5)                                  The Guarantors will pay any present or future stamp, court or
documentary taxes, or any other excise or property taxes, charges or similar
levies which arise in a Relevant Taxing Jurisdiction from the execution,
delivery or registration of the Notes, this Guarantee or under any of the
Guarantor Security Documents and any such taxes, charges or similar levies
imposed by any jurisdiction resulting from, or required to be paid in
connection with the enforcement of the Notes, this Guarantee or under 

 

12

 

any of the Guarantor
Security Documents or any other such document or instrument following the occurrence
of any Event of Default with respect to the Notes.

 

(6)                                  The provisions of this Section 3.13 survive the termination of this
Guarantee.

 

Section 3.14                                        Judgment Currency.

 

(1)                                  If for the purposes of obtaining judgment in any court it is necessary
to convert all or any part of the Note Obligations or any other amount due to a
Secured Creditor in respect of any Guarantor’s obligations under this Guarantee
in any currency (the “Original Currency”)
into another currency (the “Other Currency”),
each of the Guarantors, to the fullest extent that it may effectively do so,
agrees that the rate of exchange used shall be that at which, in accordance
with normal banking procedures, the Secured Creditor could purchase the
Original Currency with the Other Currency on the Business Day preceding that on
which final judgment is paid or satisfied.

 

(2)                                  The obligations of any Guarantor in respect of any sum due in the
Original Currency from it to any Secured Creditor shall, notwithstanding any
judgment in any Other Currency, be discharged only to the extent that on the
Business Day following receipt by such Secured Creditor of any sum adjudged to
be so due in such Other Currency such Secured Creditor may, in accordance with
its normal banking procedures, purchase the Original Currency with such Other
Currency.  If the amount of the Original
Currency so purchased is less than the sum originally due to the Secured
Creditor in the Original Currency, each of the Guarantors agrees, as a separate
obligation and notwithstanding any such judgment, to indemnify the Secured
Creditor against such loss, and if the amount of the Original Currency so
purchased exceeds the sum originally due to the Secured Creditor in the
Original Currency, the Secured Creditor agrees to remit such excess to the
Guarantor.

 

ARTICLE 4

GENERAL

 

Section 4.1                                               Notices, etc.

 

Any notices, directions or other communications
provided for in this Guarantee must be in writing and given in accordance with
the Indenture.

 

Section 4.2                                               Addition of Guarantors.

 

Each of the Guarantors shall cause each
Subsidiary of such Guarantor which, from time to time, after the date hereof
shall be required, pursuant to the provisions of the Indenture or which the
Issuers elect pursuant to the terms of the Indenture to have guarantee the Note
Obligations in favour of the Trustee on behalf of the Secured Creditors
pursuant to the terms of this Guarantee, to execute and deliver to the Trustee
on behalf of the Secured Creditors a Joinder Agreement substantially in the
form of Schedule “B” within thirty (30) days of the date on which it was
acquired or created.  Effective from and
after the date of the execution and delivery by any Person to the Trustee and
the other Secured Creditors of a Joinder Agreement, such Person shall be, and
shall be deemed for all purposes to be, a Guarantor under this Guarantee with
the same force and effect, and 

 

13

 

subject to the same
agreements, representations, guarantees, indemnities, liabilities and
obligations, as if such Person were, effective as of such date, an original
signatory to this Guarantee as a Guarantor. 
The execution and delivery of a Joinder Agreement by any Person shall
not require the consent of any other Guarantor and all of the obligations of each
Guarantor under this Guarantee shall remain in full force and effect
notwithstanding the addition of any additional Guarantor to this Guarantee.

 

Section 4.3                                               No Merger, Survival of Representations and Warranties.

 

The covenants of each of the Guarantors in this
Guarantee survive the execution and delivery of this Guarantee and the issuance
of Notes under the Indenture. 
Notwithstanding any investigation made by or on behalf of the Trustee or
the other Secured Creditors, the covenants in this Guarantee continue in full
force and effect.

 

Section 4.4                                               Further Assurances.

 

(1)                                  Each of the Guarantors will do all acts and things and execute and
deliver, or cause to be executed and delivered, all documents and instruments
that the Trustee may reasonably request to give full effect to this Guarantee
and to perfect and preserve the rights and powers of the Trustee and the other
Secured Creditors under this Guarantee, including any acknowledgements and
confirmations of this Guarantee and the Guarantor Security Documents.

 

(2)                                  Each of the Guarantors acknowledges and confirms that the Guarantor
itself has established its own adequate means of obtaining from each Issuer on
a continuing basis all information desired by such Guarantor concerning the
financial condition of such Issuer and that such Guarantor will look to such
Issuer and not to the Trustee or the other Secured Creditors, in order for such
Guarantor to keep adequately informed of changes in such Issuer’s financial
condition.

 

Section 4.5                                               Successors and Assigns.

 

This Guarantee is binding upon each of the
Guarantors, their respective successors and assigns, and enures to the benefit
of each of the Secured Creditors and each of their respective successors
permitted transferees and permitted assigns. 
No other Person (including any other creditor of any Guarantor) shall
have any interest herein or any right or benefit with respect hereto.  Without limiting the generality of the
foregoing, any Secured Creditor may assign or otherwise transfer any
indebtedness held by it secured by this Guarantee to any other Person, and such
other Person shall thereupon become vested with all the benefits in respect
thereof granted to such Secured Creditor, herein or otherwise.  No Guarantor may assign, transfer or delegate
any of its rights or obligations under this Guarantee without the prior written
consent of the Trustee which may be unreasonably withheld, except pursuant to
transactions permitted under the Indenture.

 

Section 4.6                                               Amendment.

 

This Guarantee may only be amended, supplemented
or otherwise modified by written agreement executed by the Trustee and each of
the Guarantors affected by such amendment, supplement or modification.

 

14

 

Section 4.7                                               Waivers, etc.

 

(1)                                  No consent or waiver by the Trustee or the other Secured Creditors in
respect of this Guarantee is binding unless made in writing and signed by an
authorized officer of the Trustee.  Any
consent or waiver given under this Guarantee is effective only in the specific
instance and for the specific purpose for which given.  No waiver of any of the provisions of this
Guarantee constitutes a waiver of any other provision.

 

(2)                                  A failure or delay on the part of the Trustee or any other Secured
Creditor in exercising a right under this Guarantee does not operate as a
waiver of, or impair, any right of the Trustee or such other Secured Creditor
however arising.  A single or partial
exercise of a right on the part of the Trustee or the other Secured Creditors
does not preclude any other or further exercise of that right or the exercise
of any other right by the Trustee or such other Secured Creditors.

 

Section 4.8                                               Severability.

 

If any court of competent jurisdiction from
which no appeal exists or is taken, determines that any provision of this
Guarantee is illegal, invalid or unenforceable, that provision will be severed
from this Guarantee and the remaining provisions will remain in full force and
effect.

 

Section 4.9                                               Enforcement.

 

The Trustee on behalf of the Secured Creditors
agrees that the enforcement of this Guarantee is subject to the terms of the
Indenture, including Section 6.06 thereof.

 

Section 4.10                                        Application of Proceeds.

 

All monies collected by the Trustee or any
other Secured Creditor under this Guarantee will be applied as provided in the
Indenture.  To the extent any other
Indenture Document requires proceeds of collateral under such Indenture
Document to be applied in accordance with the provisions of this Guarantee, the
Trustee or holder under such other Indenture Document shall apply such proceeds
in accordance with this Section.

 

Section 4.11                                        Governing Law.

 

(1)                                  This Guarantee will be governed by, interpreted and enforced in
accordance with the laws of the Province of Alberta and the federal laws of
Canada applicable therein.

 

(2)                                  Each Guarantor irrevocably attorns and submits to the exclusive
jurisdiction of any court of competent jurisdiction of the Province of Alberta
sitting in Calgary, Alberta in any action or proceeding arising out of or
relating to this Guarantee and the other Indenture Documents to which it is a
party.  Each Guarantor irrevocably waives
objection to the venue of any action or proceeding in such court or that such
court provides an inconvenient forum. 
Nothing in this Section limits the right of the Trustee to bring
proceedings against any Guarantor in the courts of any other jurisdiction.

 

(3)                                  Each Guarantor hereby irrevocably consents to the service of any and all
process in any such action or proceeding by the delivery of copies of such
process to such 

 

15

 

Guarantor at the
address set forth in Section 4.1 hereof. 
Nothing in this Section affects
the right of the Trustee to serve process in any manner permitted by law.

 

Section 4.12                                        General
Limitation on Guarantee Obligations

 

In any action or proceeding involving any state
corporate limited partnership or limited liability company law, or any
applicable state, federal or foreign bankruptcy, insolvency, reorganization or
other law affecting the rights of creditors generally, if the obligations of
any Guarantor under Article 2 would otherwise be held or determined to be
void, voidable, invalid or unenforceable, or subordinated to the claims of any
other creditors, on account of the amount of its liability under Article 2,
then, notwithstanding any other provision to the contrary, the amount of such
liability shall, without any further action by such Guarantor, any Credit Party
or any other person, be automatically limited and reduced to the highest amount
(after giving effect to any right of contribution established hereunder) that
is valid and enforceable and not subordinated to the claims of other creditors
as determined in such action or proceeding.

 

Section 4.13                                        Release of Guarantors.

 

A Guarantor shall be released from its
obligations under its Guarantees and its obligations under the other Indenture
Documents:

 

(1)                                  in the event of a sale or other disposition of all or substantially all
of the assets of such Guarantor, by way of merger, consolidation or otherwise,
or a sale or other disposition of all of the Equity Interests of such Guarantor
then held by Gibson Energy and the Restricted Subsidiaries;

 

(2)                                  if such Guarantor is designated as an Unrestricted Subsidiary, otherwise
becomes an Excluded Subsidiary or otherwise ceases to be a Restricted
Subsidiary, in each case in accordance with the provisions of the Indenture,
upon effectiveness of such designation or when it first becomes an Excluded
Subsidiary or ceases to be a Restricted Subsidiary, respectively in each case
in accordance with the Indenture; or

 

(3)                                  upon payment in full of the principal of, and accrued and unpaid
interest and premium, if any, and Additional Interest, if any, on the Notes and
payment in full of all other Note Obligations with respect to such Notes that
are due and payable at or prior to the time such principal, accrued and unpaid
interest and premium are paid.

 

Section 4.14                                        Right of Contribution

 

Each Guarantor hereby agrees that to the extent
that a Guarantor shall have paid more than its proportionate share of any
payment made hereunder or under the other Indenture Documents, such Guarantor
shall be entitled to seek and receive contribution from and against any other
Guarantor hereunder which has not paid its proportionate share of such
payment.  Each Guarantor’s right of
contribution shall be subject to the terms and conditions of Section 3.6.  The provisions of this Section 4.14
shall in no respect limit the obligations and liabilities of any Guarantor to
the Agent and each Guarantor shall remain liable to the Agent and the Lenders
for the full amount guaranteed by such Guarantor hereunder.

 

16

 

Section 4.15                                        Business Corporations Act

 

To the extent required pursuant to Section 45
of the Business Corporations Act (Alberta),
each of the Guarantors hereby consents to the entering into of the transactions
contemplated in the Indenture and this Guarantee (including the giving of
guarantees and the granting of security) by each of the other Credit Parties.

Ladies and Gentlemen:

 

Reference is made to the Guarantee-Subsidiary Guarantors
(as amended, amended and restated, supplemented or otherwise modified from time
to time, the “Guarantee”; capitalized terms used
but not otherwise defined herein shall have the meanings assigned to such terms
in the Guarantee), dated as of ·,
2009 made by Moose Jaw
Refinery Partnership, Moose Jaw Refinery ULC, CanWest Propane Partnership,
CanWest Propane ULC, MP Energy Partnership, MP Energy ULC, Gibson Energy
Partnership, GEP ULC, Link Petroleum Services Ltd., Chief Hauling Contractors
ULC, Gibson GCC Inc., Battle River Terminal GP Inc., Battle River Terminal LP
and Bridge Creek Trucking Ltd. (each an “Guarantor”
and together the “Guarantors”) in
favour of The Bank of New York Mellon, as Trustee (in such capacity and
together with any successors and permitted assigns in such capacity, the “Trustee”) and the other Secured Creditors (as defined
therein).

 

This Joinder Agreement supplements the Guarantee and
is delivered by the undersigned, [                    ]
(the “New Guarantor”), pursuant to Section 4.2
of the Guarantee. The New Guarantor hereby agrees to be bound as a Guarantor
party to the Guarantee by all of the terms, covenants and conditions set forth
in the Guarantee to the same extent that it would have been bound if it had
been a signatory Guarantor to the Guarantee on the date of the Guarantee. Without
limiting the generality of the foregoing, the New Guarantor guarantees to each
of the Secured Creditors the due and punctual payment, and the due performance,
whether at stated maturity, by acceleration or otherwise, of the Note
Obligations. The New Guarantor also expressly assumes all obligations and
liabilities of a Guarantor thereunder. The New Guarantor hereby makes each of
the representations and warranties and agrees to each of the covenants
applicable to the Guarantors contained in the Guarantee.

 

Annexed hereto are supplements to each of the
schedules to the Guarantee with respect to the New Guarantor. Such supplements
shall be deemed to be part of the Guarantee.

 

This Joinder Agreement and any amendments, waivers,
consents or supplements hereto may be executed in any number of counterparts
and by different parties hereto in separate counterparts, each of which when so
executed and delivered shall be deemed to be an original, but all such
counterparts together shall constitute one and the same agreement.

 

 

This Joinder Agreement will be governed by,
interpreted and enforced in accordance with, the laws of the Province of
Alberta and the federal laws of Canada applicable therein.

 

IN WITNESS WHEREOF, the New
Guarantor has caused this Joinder Agreement to be executed and delivered by its
duly authorized officer as of the date first above written.
