     2. LOANS AND TERMS OF PAYMENT.

each Lender  agrees  (severally,  not jointly or jointly and  severally) to make
loans (the "Advances" and, collectively,  the "Loan") to Borrower on the Closing
Date in an amount equal to such Lender's Pro Rata Share of the Loan Amount;  (b)
Use of Proceeds.  The Borrower  shall use the proceeds of the Loan for a onetime
cash distribution to Abraxas, which shall include the repayment of existing debt
to Abraxas.

         2.2 Borrowing Procedures.

         (a) Making of Advances.

               (i) Each Lender  shall make the amount of such  Lender's Pro Rata
     Share of the Borrowing  available to Agent in immediately  available funds,
     to Agent's Account, not later than 10:00 a.m. (Calgary time) on the Closing
     Date.  After  Agent's  receipt  of the  proceeds  of  such  Advances,  upon
     satisfaction  of the  conditions  precedent  set forth in  Section 3, Agent
     shall make the proceeds  thereof  available to Borrower on the Closing Date
     by transferring immediately available funds equal to such proceeds received
     by Agent to Borrower's Designated Account;  provided,  however, that, Agent
     shall not request any Lender to make, and no Lender shall make, any Advance
     if Agent shall have  actual  knowledge  that one or more of the  conditions
     precedent  set forth in Section 3 will not be satisfied on the Closing Date
     unless such condition has been waived.


               (ii) Agent may assume  that each  Lender  will make the amount of
     that Lender's Pro Rata Share of the Loan  available to Agent in immediately
     available  funds on the Closing  Date  pursuant to Section  2.2(a)(i),  and
     Agent may (but shall not be so required), in reliance upon such assumption,
     make available to Borrower on such date a corresponding  amount.  If and to
     the extent  any Lender  shall not have made its full  amount  available  to
     Agent in  immediately  available  funds  pursuant to Section  2.2(a)(i) and
     Agent in such  circumstances  has made  available to Borrower  such amount,
     that Lender shall on the Business Day  following the Closing Date make such
     amount available to Agent,  together with interest at the Interest Rate for
     each day during such period. A notice submitted by Agent to any Lender with
     respect to amounts owing under this subsection shall be conclusive,  absent
     manifest error. If such amount is so made available,  such payment to Agent
     shall constitute such Lender's Advance on the date of the Borrowing for all
     purposes of this  Agreement.  If such amount is not made available to Agent
     on the Business Day following the Closing Date,  Agent will notify Borrower
     of such failure to fund and, upon demand by Agent,  Borrower shall pay such
     amount to Agent for Agent's  account,  together with  interest  thereon for
     each day elapsed since the date of the Borrowing, at a rate per annum equal
     to the Interest  Rate. The failure of any Lender to make any Advance on the
     Closing Date shall not relieve any other Lender of any obligation hereunder
     to make an Advance on the Closing Date,  but no Lender shall be responsible
     for the failure of any other  Lender to make the Advance to be made by such
     other Lender on the Closing Date.

               (iii) Agent shall not be  obligated  to transfer to a  Defaulting
     Lender any payment  made by Borrower to Agent for the  Defaulting  Lender's
     benefit  and, in the absence of such  transfer  to the  Defaulting  Lender,
     Agent shall transfer any such payment to each other  non-Defaulting  Lender
     member of the Lender Group  ratably in  accordance  with their  Commitments
     (but only to the extent that such Defaulting Lender's Advance was funded by
     the other  members of the Lender  Group) or, if so directed by Borrower and
     if no Default or Event of Default had  occurred and is  continuing  (and to
     the extent such  Defaulting  Lender's  Advance was not funded by the Lender
     Group),  retain same to be  re-advanced  to Borrower as if such  Defaulting
     Lender had made Advances to Borrower.  Subject to the foregoing,  Agent may
     hold and, in its Permitted Discretion,  re-lend to Borrower for the account
     of such  Defaulting  Lender the amount of all such  payments  received  and
     retained by it for the account of such  Defaulting  Lender.  Solely for the
     purposes  of voting or  consenting  to  matters  with  respect  to the Loan
     Documents,  such Defaulting Lender shall be deemed not to be a "Lender" and
     such  Lender's  Commitment  shall  be  deemed  to  be  zero.  This  Section
     2.2(a)(iii)  shall remain  effective  with respect to such Lender until (x)
     the Obligations under this Agreement shall have been declared or shall have
     become immediately due and payable, (y) the non-Defaulting  Lenders,  Agent
     and Borrower shall have waived such Defaulting  Lender's default in writing
     or (z) the  Defaulting  Lender  makes its Pro Rata Share of the Advance and
     pays to Agent  all  amounts  owing by such  Defaulting  Lender  in  respect
     thereof.  The operation of this Section  2.2(a)(iii) shall not be construed
     to increase or otherwise affect the Commitment of any Lender, to relieve or
     excuse the performance by such Defaulting Lender or any other Lender of its
     duties and obligations hereunder or to relieve or excuse the performance by



     Borrower  of its duties and  obligations  hereunder  to Agent or to Lenders
     other  than  such  Defaulting  Lender.  Any  such  failure  to  fund by any
     Defaulting  Lender shall  constitute a material  breach by such  Defaulting
     Lender of this  Agreement  and shall entitle  Borrower at its option,  upon
     written notice to Agent,  to arrange for a substitute  Lender to assume the
     Commitment  of  such  Defaulting  Lender,  such  substitute  Lender  to  be
     acceptable  to  Agent.  In  connection  with  the  arrangement  of  such  a
     substitute  Lender,  the Defaulting Lender shall have no right to refuse to
     be replaced hereunder and agrees to execute and deliver a completed form of
     Assignment and Acceptance  Agreement in favor of the substitute Lender (and
     agrees that it shall be deemed to have executed and delivered such document
     if it  fails  to do so)  subject  only to  being  repaid  its  share of the
     outstanding  Obligations  without  any  premium  or  penalty  of  any  kind
     whatsoever;  provided  further,  however,  that any such  assumption of the
     Commitment  of such  Defaulting  Lender shall not be deemed to constitute a
     waiver of any of the  Lender  Groups'  or  Borrower's  rights  or  remedies
     against any such  Defaulting  Lender  arising out of or in relation to such
     failure to fund.

         (b) Notation.  Agent shall record on its books the principal amount and
type of the Advances  owing to each Lender from time to time. In addition,  each
Lender is authorized,  at such Lender's  option,  to note the date and amount of
each payment or prepayment  of principal of such Lender's  Advances in its books
and records,  including  computer records,  such books and records  constituting
conclusive  evidence,  absent manifest error, of the accuracy of the information
contained therein.

         (c)  Lenders'  Failure to Perform.  All  Advances  shall be made by the
Lenders  contemporaneously  and in accordance with their Pro Rata Shares.  It is
understood  that (i) no Lender shall be responsible for any failure by any other
Lender to perform its  obligation  to make any Advance  (or other  extension  of
credit (if any)) hereunder,  nor shall any Commitment of any Lender be increased
or  decreased  as a result of any  failure by any other  Lender to  perform  its
obligations  hereunder,  and  (ii) no  failure  by any  Lender  to  perform  its
obligations  hereunder  shall  excuse  any  other  Lender  from its  obligations
hereunder.

         2.3 Payments.

         (a) Payments by Borrower.

               (i) Except as otherwise  expressly  provided herein, all payments
     by Borrower shall be made to Agent's  Account for the account of the Lender
     Group and shall be made in immediately available funds, no later than 11:00
     a.m. (Calgary time) on the date specified  herein.  Any payment received by
     Agent  later than 11:00 a.m.  (Calgary  time)  shall be deemed to have been
     received on the following  Business Day and any applicable  interest or fee
     shall continue to accrue until such following Business Day.

               (ii) Unless Agent receives notice from Borrower prior to the date
     on which any  payment is due to Lenders  that  Borrower  will not make such
     payment in full as and when  required,  Agent may assume that  Borrower has
     made  (or  will  make)  such  payment  in full  to  Agent  on such  date in



     immediately  available  funds and Agent may (but shall not be so required),
     in reliance  upon such  assumption,  distribute  to each Lender on such due
     date an amount  equal to the  amount  then due such  Lender.  If and to the
     extent  Borrower  does not make such  payment  in full to Agent on the date
     when due, each Lender  severally shall repay to Agent on demand such amount
     distributed  to  such  Lender,   together  with  interest  thereon  at  the
     Defaulting  Lender  Rate  for  each  day  from  the  date  such  amount  is
     distributed to such Lender until the date repaid.

         (b) Apportionment and Application of Payments.

               (i) Except as  otherwise  provided  with  respect  to  Defaulting
     Lenders and except as otherwise  provided in the Loan Documents  (including
     letter  agreements,  if any,  between and/or among Agent and/or  individual
     Lenders),  aggregate  principal and interest  payments shall be apportioned
     ratably among the Lenders (according to the unpaid principal balance of the
     Obligations held by each Lender) and payments of fees and expenses shall be
     apportioned  ratably among the Lenders (other than payments  received while
     no Unmatured Default or Event of Default has occurred and is continuing and
     which   relate  to  the  payment  of  principal  or  interest  of  specific
     Obligations),  and all proceeds of Accounts or other Collateral received by
     Agent,  shall be applied (unless  otherwise agreed by the Required Lenders)
     as follows:

                    (A) first,  to pay any  Lender  Group  Expenses  then due to
          Agent under the Loan Documents, until paid in full,

                    (B) second, to pay any Lender Group Expenses then due to the
          Lenders under the Loan  Documents,  on a ratable basis,  until paid in
          full,

                    (C)  third,  to pay any fees then due to Agent (in each case
          for its  separate  account  and  after  giving  effect  to any  letter
          agreements  between  Agent  and  individual  Lenders)  under  the Loan
          Documents, until paid in full,

                    (D)  fourth,  to pay any fees  then due to any or all of the
          Lenders  (after giving effect to any letter  agreements  between Agent
          and individual Lenders) under the Loan Documents,  on a ratable basis,
          until paid in full,

                    (E) fifth,  to pay interest due in respect of the  Advances,
          until paid in full,

                    (F) sixth, to pay the principal of all Advances,  until paid
          in full,

                    (G)  seventh,  to pay any other  Obligations,  until paid in
          full, and


                    (H)  eighth,  to  Borrower  (to be wired  to the  Designated
          Account) or such other Person entitled thereto under applicable law.

               (ii) Agent promptly shall distribute to each Lender,  pursuant to
     the applicable wire instructions received from each Lender in writing, such
     funds as it may be entitled to receive.

               (iii) In each instance,  so long as no Unmatured Default or Event
     of Default has occurred and is continuing,  Section  2.3(b)(i) shall not be
     deemed to apply to any payment by Borrower  specified by Borrower to be for
     the payment of  specific  Obligations  then due and payable (or  prepayable
     under any provision of this Agreement).

               (iv) For purposes of the foregoing,  "paid in full" means payment
     of all  amounts  owing  under  the Loan  Documents  according  to the terms
     thereof,  including loan fees, service fees,  professional  fees,  interest
     (and specifically  including interest accrued after the commencement of any
     Insolvency Proceeding),  default interest, interest on interest and expense
     reimbursements,  whether  or  not  the  same  would  be  or is  allowed  or
     disallowed in whole or in part in any Insolvency Proceeding.

               (v) In the  event  of a  direct  conflict  between  the  priority
     provisions of this Section 2.3 and other provisions  contained in any other
     Loan Document, it is the intention of the parties hereto that such priority
     provisions in such documents  shall be read together and construed,  to the
     fullest extent possible,  to be in concert with each other. In the event of
     any actual,  irreconcilable  conflict that cannot be resolved as aforesaid,
     the terms and provisions of this Section 2.3 shall control and govern.

         2.4 Repayment of Obligations.

         (a) Promise to Pay.  Borrower  hereby  promises to pay the  Obligations
(including  principal,  interest,  fees,  costs and expenses) in U.S. Dollars in
full to the  Lender  Group as and when due and  payable  under the terms of this
Agreement and the other Loan Documents.

         (b) Scheduled  Principal  Payments.  Without limiting  Sections 2.13 or
9.1(a), Borrower will make the following scheduled principal payments:

                    (i) on the first anniversary hereof, U.S. $1,750,000;

                    (ii) on the second anniversary hereof, U.S. $1,750,000;

                    (iii) on the third anniversary hereof, U.S. $1,750,000;

                    (iv) on the fourth anniversary hereof, U.S. $3,500,000; and

                    (v) on the  Maturity  Date,  the  principal  and  any  other
          amounts that remain outstanding hereunder.


         2.5 Interest Rates; Payments and Calculations.

         (a)  Interest  Rates.  Except as  provided  in clause  (b)  below,  all
Obligations,  whether or not charged to the Loan  Account  pursuant to the terms
hereof,  shall bear  interest on the Daily  Balance  thereof at a per annum rate
equal to the Interest Rate.

         (b) Default Rate. Upon the occurrence and during the continuation of an
Event of Default  (and at the election of Agent or the  Required  Lenders),  all
Obligations,  whether or not charged to the Loan  Account  pursuant to the terms
hereof,  shall bear  interest on the Daily  Balance  thereof at a per annum rate
equal to 4.00  percentage  points above the per annum rate otherwise  applicable
hereunder.

         (c) Payment.

               (i)  Interest  in  respect  of the  Obligations  shall be due and
     payable,  in arrears,  on the first Business Day of each calendar  quarter,
     beginning on January 1, 2005, at any time that  Obligations are outstanding
     (each such date, an "Interest  Payment Date").  All fees payable  hereunder
     shall be due and  payable  on the date  upon  which  such  fees are due and
     payable  hereunder.  Borrower hereby  authorizes  Agent,  from time to time
     without prior notice to Borrower,  to, and Agent agrees that it may (at its
     sole and absolute  discretion),  charge such interest and fees,  all Lender
     Group Expenses (as and when  incurred),  the fees and costs provided for in
     Section 2.10 (as and when accrued or  incurred)  and all other  payments as
     and when due and  payable  under  any Loan  Document,  to  Borrower's  Loan
     Account,  which amounts  thereafter shall be deemed to constitute  Advances
     hereunder and shall accrue interest at the rate then applicable to Advances
     hereunder.  Any  interest  not paid when due shall be  compounded  by being
     charged  to  Borrower's  Loan  Account  and shall  thereafter  be deemed to
     constitute an Advance  hereunder  and shall accrue  interest at a per annum
     rate equal to the Interest Rate in existence from time to time.

               (ii) All interest  accruing on Obligations  pursuant to the terms
     of this Agreement  shall be payable in immediately  available  funds on the
     respective Interest Payment Date.

         (d)  Computation.  All  interest  and fees  chargeable  under  the Loan
Documents shall be computed on the basis of a 360-day year for the actual number
of days  elapsed.  The  rates of  interest  hereunder  based  upon the Base Rate
automatically and immediately shall be increased or decreased by an amount equal
to any change in the Base Rate.

         (e) Maximum Rate of Return. Notwithstanding any provision herein to the
contrary,  in no event will the aggregate  "interest" (as defined in Section 347
of the Criminal Code (Canada))  payable under this Agreement  exceed the maximum
effective  annual rate of interest on the "credit  advanced" (as defined in that
Section 347)  permitted  under that section and, if any payment,  collection  or
demand  pursuant to this  Agreement in respect of "interest" (as defined in that
Section 347) is determined to be contrary to the provisions of that Section 347,
such  payment,  collection  or demand will be deemed to have been made by mutual



mistake of Borrower and the applicable Lenders and the amount of such payment or
collection  will be refunded to Borrower.  For purposes of this  Agreement,  the
effective  annual  rate  of  interest  will be  determined  in  accordance  with
generally  accepted  actuarial  practices and  principles  over the term of this
Agreement on the basis of annual  compounding of the lawfully  permitted rate of
interest and, in the event of dispute, a certificate of a Fellow of the Canadian
Institute of Actuaries appointed by Agent will be prima facie evidence,  for the
purposes of such determination.

         2.6 Cash  Management.  The Borrower  shall  establish and maintain cash
management services in accordance with the terms of the Collateral Documents.

         2.7 Crediting Payments.  The receipt of any payment item by Agent shall
not be  considered  a payment  on account  unless  such  payment  item is a wire
transfer of immediately  available  funds made to Agent's  Account or unless and
until such  payment  item is honored  when  presented  for  payment.  Should any
payment item not be honored when  presented for payment,  then Borrower shall be
deemed  not  to  have  made  such  payment  and  interest  shall  be  calculated
accordingly.  Anything to the contrary  contained  herein  notwithstanding,  any
payment  item  shall be deemed  received  by Agent only if it is  received  into
Agent's Account on a Business Day on or before 11:00 a.m. (Calgary time). If any
payment item is received  into Agent's  Account on a  non-Business  Day or after
11:00 a.m.  (Calgary  time) on a Business  Day,  it shall be deemed to have been
received by Agent as of the opening of  business  on the  immediately  following
Business Day.

         2.8 Designated Account.  Agent is authorized to make the Advances under
this Agreement based upon telephonic or other instructions  received from anyone
purporting to be an Authorized  Person,  or without  instructions if pursuant to
Section 2.5(c). Borrower agrees to establish and maintain the Designated Account
with the  Designated  Account Bank for the purpose of receiving  the proceeds of
the Advances made hereunder.  Unless otherwise agreed by Agent and Borrower, any
Advance made hereunder shall be made to the Designated Account.

         2.9 Maintenance of Loan Account; Statements of Obligations. Agent shall
maintain an account on its books in the name of Borrower (the "Loan Account") on
which  Borrower  will be charged with all Advances made by (or deemed to be made
by) Agent or the  Lenders to Borrower  or for  Borrower's  account and all other
payment  Obligations  hereunder  or under the other  Loan  Documents,  including
accrued  interest,  fees and expenses and Lender Group  Expenses.  In accordance
with Section 2.7, the Loan Account will be credited  with all payments  received
by Agent from Borrower or for Borrower's account.  Agent shall render statements
regarding the Loan Account to Borrower, including principal,  interest, fees and
an  itemization of all charges and expenses  constituting  Lender Group Expenses
owing, and each such statement shall be conclusively  presumed to be correct and
accurate and constitute an account stated between  Borrower and the Lender Group
unless, within 30 days after receipt thereof by Borrower, Borrower shall deliver
to Agent written objection  thereto  describing the error or errors contained in
any such statements.


         2.10 Fees and Charges.  Borrower  shall pay to Agent the following fees
and  charges,   which  fees  and  charges  shall  be  non-refundable  when  paid
(irrespective of whether this Agreement is terminated thereafter):

               (a) Closing Fees.  Borrower will pay or cause to be paid to Agent
a closing fee as and when due and payable under the terms of the Fee Letter.

               (b) Audit,  Appraisal  and  Valuation  Charges.  For the separate
account of Agent,  Borrower  shall pay audit,  appraisal and valuation  fees and
charges as follows,  a fee of U.S.  $850 per day, per auditor (such fees for all
auditors  for any  single  financial  audit  not to  exceed  U.S.  $5,000 in the
aggregate),  plus  out-of-pocket  expenses for each financial  audit of Borrower
performed by personnel  employed by Agent, (ii) a fee of U.S. $1,500 per day per
appraiser,  plus  out-of-pocket  expenses,  for each appraisal of the Collateral
performed by personnel  employed by Agent,  and (iii) the actual charges paid or
incurred  by Agent if it elects  to employ  the  services  of one or more  third
Persons to perform financial audits of Borrower, to appraise the Collateral,  or
any portion thereof, to review or examine the Oil and Gas Properties of Borrower
or to assess Borrower's business valuation,  provided, that, (x) with respect of
clause (i)  above,  so long as no Event of Default  shall have  occurred  and be
continuing,  Borrower shall not be obligated to pay for more than four financial
audits  during any  calendar  year and (y) with  respect to any  Reserve  Report
requested by Borrower or Agent (in addition to the Reserve  Reports  required to
be delivered semi-annually by Borrower to Agent pursuant to Section 6.2(e)), the
party  requesting  the issuance of such  Reserve  Report shall pay the costs and
expenses associated therewith in the absence of a continuing Default or Event of
Default (and during a continuing Default, Unmatured Default or Event of Default,
such Reserve Report shall be at Borrower's sole cost and expense).

               (c) Lender Group  Expenses.  Lender Group  Expenses in accordance
with Section 16.17, or, if earlier,  upon demand of Agent or any Lender entitled
thereto.

determines  that (i) the adoption of or change in any law,  rule,  regulation or
guideline regarding capital requirements for banks or bank holding companies, or
any change in the  interpretation  or  application  thereof by any  Governmental
Authority charged with the  administration  thereof,  or (ii) compliance by such
Lender or its  parent  bank  holding  company  with any  guideline,  request  or
directive of any such entity regarding  capital adequacy  (whether or not having
the force of law),  the effect of reducing  the return on such  Lender's or such
holding  company's  capital  as  a  consequence  of  such  Lender's  Commitments
hereunder to a level below that which such Lender or such holding  company could
have  achieved  but  for  such  adoption,  change  or  compliance  (taking  into
consideration  such Lender's or such holding  company's  then existing  policies
with  respect to capital  adequacy and  assuming  the full  utilization  of such
entity's capital) by any amount deemed by such Lender to be material,  then such
Lender may notify Borrower and Agent thereof.  Following receipt of such notice,
Borrower  agrees to pay such  Lender on demand the amount of such  reduction  of
return of capital as and when such  reduction is  determined,  payable within 90
days after  presentation by such Lender of a statement in the amount and setting
forth in reasonable detail such Lender's calculation thereof and the assumptions
upon which such  calculation was based (which statement shall be deemed true and



correct absent manifest error). In determining such amount,  such Lender may use
any reasonable averaging and attribution methods.

         2.12 Registered Loans and Registered  Notes.  Borrower agrees to record
each  Advance on the  Register  referred  to in Section  14.1(h).  Each  Advance
recorded  on  the  Register  (a  "Registered  Loan")  may  not be  evidenced  by
promissory  notes  other than  Registered  Notes (as  defined  below).  Upon the
registration of any Advance,  Borrower agrees,  at the request of any Lender, to
execute and deliver to such Lender a promissory  note,  in  conformity  with the
terms of this Agreement, in registered form to evidence such Registered Loan, in
form and  substance  reasonably  satisfactory  to Agent  and  such  Lender,  and
registered as provided in Section 14.1(h) (a "Registered Note"),  payable to the
order  of such  Lender  and  otherwise  duly  completed.  Once  recorded  on the
Register,  each  Advance may not be removed  from the  Register so long as it or
they  remain  outstanding,  and a  Registered  Note may not be  exchanged  for a
promissory note that is not a Registered Note.

         2.13 Repayment of Advances.  Without limiting Section 2.4(b),  Borrower
may prepay  Advances at any time without  payment of any  prepayment  premium or
other  prepayment  fee,  but subject to Section 3.4, if  applicable,  and to the
following terms and conditions:

               (a) Borrower shall have provided 10 days' prior written notice to
Agent of the prepayment date and the amount of such prepayment;

               (b) any such prepayment shall be in a minimum amount equal to the
lesser of (x) U.S.  $1,000,000 and (y) the aggregate  unpaid principal amount of
the Loan then outstanding;

               (c)  except  for any  such  prepayment  in  connection  with  the
termination  of this  Agreement  pursuant to Section 3.4,  each such  prepayment
shall occur on and be effective as of an Interest Payment Date; and

               (d) any such prepayment shall be applied to the principal amounts
payable in accordance with Section 2.4 in reverse order of maturity.

the Closing  Date,  as though made on and as of the Closing  Date (except to the
extent that such  representations  and  warranties  relate  solely to an earlier
date, in which case such representations and warranties shall have been true and
correct on and as of such earlier date);

               (r) no  Default or Event of Default  shall have  occurred  and be
continuing on the Closing  Date,  nor shall either result from the making of the
Loan; and

               (s) no injunction,  writ, restraining order or other order of any
nature prohibiting, directly or indirectly, the extending of the Loan shall have
been issued and remain in force by any Governmental  Authority against Borrower,
Agent, any Lender or any of their Affiliates.

         3.2 Term. This Agreement shall become  effective upon the execution and
delivery hereof by Borrower,  Agent and Lenders and shall continue in full force



and effect for a term  ending the day after the fifth (5th)  anniversary  of the
Closing Date (the "Maturity Date").  The foregoing  notwithstanding,  the Lender
Group,  upon the  election  of the  Required  Lenders,  shall  have the right to
terminate its  obligations  under this Agreement  immediately and without notice
upon the occurrence and during the continuation of an Event of Default.

         3.3  Effect  of  Termination.  On  the  date  of  termination  of  this
Agreement,  all  Obligations  immediately  shall become due and payable  without
notice or demand.  No termination of this Agreement,  however,  shall relieve or
discharge Borrower of its respective duties,  Obligations or covenants hereunder
and Agent's  Liens in the  Collateral  (with respect to the  Obligations)  shall
remain in effect until all  Obligations  have been fully and finally  discharged
and any  obligation of Lender to provide  additional  credit  hereunder has been
terminated.  When this Agreement has been  terminated and all of the Obligations
have been fully and finally  discharged  and any obligation of Lender to provide
additional  credit under the Loan  Documents  has been  terminated  irrevocably,
Agent will,  at  Borrower's  sole  expense,  execute  and  deliver any  personal
property  registry  discharge  statements,  lien  releases,  mortgage  releases,
re-assignments of trademarks, discharges of security interests and other similar
discharge or release  documents (and, if applicable,  in recordable form) as are
reasonably  necessary  to  release,  as of record,  the Liens of Agent,  and all
notices of security  interests and liens previously  filed,  with respect to the
Obligations.

         3.4 Early  Termination.  Without limiting Section 2.13,  Borrower shall
have the option,  at any time upon 10 days' prior  written  notice to Agent,  to
terminate this Agreement by paying to Agent, on any Business Day (which need not
be an Interest  Payment Date),  in cash, the then  outstanding  Obligations,  in
full. If Borrower has sent a notice of termination pursuant to the provisions of
this Section 3.4,  then  Borrower  shall be  irrevocably  obligated to repay the
Obligations,  in full, on the date set forth as the date of  termination of this
Agreement in such notice.

     4. SECURITY.

         4.1 Security.  The present and future Indebtedness of Borrower to Agent
and Lenders under the Loan and all other  Indebtedness  of Borrower to Agent and
Lenders,  howsoever arising or incurred hereunder and under the Documents,  will
be secured by the following (collectively, the "Security"):

               (a) a demand  debenture (the  "Debenture")  in the amount of Cdn.
$75,000,000  from Borrower  (the  Debenture to be  substantially  in the form of
Schedule 4.1), to be registered in all appropriate jurisdictions; and

               (b) such documents and instruments, as may be requested by Agent,
in its sole discretion,  providing a fixed Lien,  including without  limitation,
caveats,  security notices and such other similar documentation,  to be filed or
registered in such public registry offices in Canada or any province thereof.

         4.2 Sharing of  Security.  Borrower and Lenders  agree and  acknowledge
that the Security is being shared  equally among Lenders to secure  Indebtedness
of  Borrower  under the Loan and any hedging  transactions  with any Lender on a



pari passu basis; and that Agent will hold the Security for the benefit of Agent
and Lenders hereunder.

         4.3  Exclusivity  of  Remedies.  Nothing  herein  contained  or in  the
Security  now held or hereafter  acquired by Agent and  Lenders,  nor any act or
omission of Agent and Lenders with respect to any such Security, will in any way
prejudice  or affect the rights,  remedies  or powers of Agent and Lenders  with
respect to any other security at any time held by Agent and Lenders.

         4.4 Form of  Security.  The  Security  will be in such form or forms as
will be required by Agent,  acting  reasonably,  and will be  registered in such
offices in Canada or the U.S. or any province or state thereof as Agent may from
time to time  reasonably  require to protect the Liens created  thereby.  Should
Agent  determine  at any time and from time to time that the form and  nature of
the then  existing  Security is deficient  in any way or does not fully  provide
Agent  and  Lenders  with the  Liens  and  priority  to which  each is  entitled
hereunder,  Borrower will forthwith  execute and deliver or cause to be executed
and delivered to Agent, at Borrower's  expense,  such amendments to the Security
or provide such new security as Agent may reasonably request.

         4.5 After-Acquired  Property.  All property acquired by or on behalf of
Borrower  after the date of execution  of the  Security  which forms part of the
property of Borrower or any Subsidiary  (hereafter  collectively  referred to as
"After-Acquired  Property"), will be subject to the Security without any further
conveyance, mortgage, pledge, charge, assignment or other act on the part of the
parties hereto. Without limiting the effect of the preceding sentence,  Borrower
will,  or will cause such  Subsidiary  to, from time to time execute and deliver
and  Agent  will  register,   all  at  Borrower's   expense,   such  instruments
supplemental  to the  Security,  in form and  substance  satisfactory  to Agent,
acting reasonably,  as may be necessary or desirable to ensure that the Security
as  amended  and  supplemented  constitutes  in favour of Agent and  Lenders  an
effective Lien (including without  limitation,  a fixed Lien pursuant to Section
4.6) to the extent created by the Security over such After-Acquired  Property as
required  hereunder,   subject  only  to  Permitted   Encumbrances  which  under
applicable law rank in priority thereto.

         4.6  Undertaking  to Grant Fixed Charge  Security.  If Lenders,  acting
reasonably,  determine in their sole  discretion  that it is necessary for their
adequate protection,  Borrower, at the request of Agent, will forthwith grant or
cause to be  granted  to Agent for the  benefit  of Agent and  Lenders a further
fixed Lien (subject only to Permitted  Encumbrances  which under  applicable law
rank in priority  thereto) in such of Borrower's  property as Agent will, in its
sole  discretion,  determine  as  security  for  all  then  present  and  future
Indebtedness  of  Borrower  to  Agent  and  Lenders  under  the  Loan.  In  this
connection, Borrower will:

               (a) provide Agent with such information as is reasonably required
by Agent to identify the property to be charged pursuant to this Section 4.6;

               (b) do all such things as are  reasonably  required to grant,  in
favour  of  Agent  and  Lenders,   a  fixed  Lien  (subject  only  to  Permitted
Encumbrances  which under applicable law rank in priority thereto) in respect of



such property to be so charged pursuant to this Section 4.6;

               (c) provide Agent with all corporate or  partnership  resolutions
and other action,  as reasonably  required,  for Borrower or such  Subsidiary to
grant the  fixed  Lien  (subject  only to  Permitted  Encumbrances  which  under
applicable law rank in priority thereto) in the property  identified by Agent to
be so charged;

               (d)  provide  Agent  with  such  security  instruments  and other
documents which Agent, acting reasonably, deems are necessary to give full force
and effect to the provisions of this Section 4.6;

               (e)  assist  Agent  in the  registration  or  recording  of  such
agreements  and  instruments  in such public  registry  offices in Canada or any
province thereof as Agent, acting reasonably, deems necessary to give full force
and effect to the provisions of this Section 4.6; and

               (f) pay all  reasonable  costs and expenses  incurred by Agent in
connection with the  preparation,  execution and registration of all agreements,
documents and  instruments,  including any  amendments to the Security,  made in
connection with this Section 4.6.

         4.7  Discharge  of  Security.  Agent and  Lenders  will  discharge  the
Security at Borrower's  expense  forthwith after all of Borrower's  Indebtedness
under the Loan has been  unconditionally  and  irrevocably  paid or satisfied in
full and each such facility has been cancelled.

         4.8 Negotiable Collateral. In the event that any Collateral,  including
proceeds,  is evidenced by or consists of Negotiable  Collateral,  and if and to
the extent that perfection or priority of Agent's security interest is dependent
on or enhanced by possession,  Borrower,  immediately upon the request of Agent,
shall endorse and deliver physical  possession of such Negotiable  Collateral to
Agent.

         4.9  Collection  of  Accounts,  General  Intangibles,   and  Negotiable
Collateral.  At any time after the occurrence and during the  continuation of an
Event of Default,  Agent or Agent's  designee may (a) notify Account  Debtors of
Borrower  that the  Accounts,  chattel  paper or General  Intangibles  have been
assigned to Agent or that Agent has a security  interest  therein or (b) collect
the  Accounts,  chattel  paper or General  Intangibles  directly  and charge the
collection costs and expenses to the Loan Account.  Borrower agrees that it will
hold in trust for Lender Group, as Lender Group's trustee,  any Collections that
it receives and  immediately  will deliver  said  Collections  to Agent in their
original form as received by Borrower.

         4.10 Power of Attorney.  Borrower hereby irrevocably makes, constitutes
and appoints Agent (and any of Agent's officers,  employees or agents designated
by Agent), as Borrower's true and lawful attorney, with power to (a) if Borrower
refuses  to,  or fails  timely  to  execute  and  deliver  any of the  documents
described  in Section  4.4,  sign the name of Borrower  on any of the  documents



described  in Section 4.4, (b) at any time that an Event of Default has occurred
and is  continuing,  sign  Borrower's  name on any  invoice  or  bill of  lading
relating to the Collateral, drafts against Account Debtors or notices to Account
Debtors, (c) send requests for verification of Accounts,  (d) endorse Borrower's
name on any Collection item that may come into Lender Group's possession, (e) at
any time that an Event of Default has occurred and is continuing,  make,  settle
and  adjust all claims  under  Borrower's  policies  of  insurance  and make all
determinations  and decisions with respect to such policies of insurance and (f)
at any time that an Event of Default has occurred and is continuing,  settle and
adjust  disputes and claims  respecting  the Accounts,  chattel paper or General
Intangibles directly with Account Debtors, for amounts and upon terms that Agent
determines  to be  reasonable,  and Agent may cause to be executed and delivered
any  documents  and  releases  that  Agent  determines  to  be  necessary.   The
appointment  of Agent as  Borrower's  attorney,  and each and  every  one of its
rights and powers,  being coupled with an interest,  is irrevocable until all of
the Obligations  have been fully and finally repaid and performed and the Lender
Group's obligations to extend credit hereunder are terminated.

         4.11 Right to  Inspect.  Agent and each  Lender  (through  any of their
respective  officers,  employees or agents) shall have the right, upon notice to
Borrower,  which notice shall not be required upon the occurrence and during the
continuance  of an Event of Default,  from time to time hereafter to inspect the
Books and to check,  test and appraise the Collateral and review and examine the
Oil and Gas  Properties  of  Borrower  and its  Subsidiaries  in order to verify
Borrower's financial condition or the amount,  quality,  value, condition of, or
any other matter relating to, the Collateral.

         4.12  Control  Agreements.  Borrower  agrees that it will not  transfer
assets out of any Securities Accounts other than as permitted under Section 7.19
and,  if to another  securities  intermediary,  unless  Borrower,  Agent and the
substitute  securities  intermediary  have  entered  into a  Control  Agreement.
Borrower  hereby agrees to take any and all action that Agent  requests in order
for Agent to obtain control in accordance with Sections 9-104,  9-105, 9-106 and
9-107 of the New York Uniform  Commercial  Code with  respect to any  Securities
Accounts, DDA's, chattel paper, investment property and letter-of-credit rights.
No arrangement contemplated hereby or by any Control Agreement in respect of any
Securities  Accounts or other  investment  property or DDA,  electronic  chattel
paper or letter-of-credit rights shall be modified by Borrower without the prior
written  consent of Agent.  Upon the occurrence and during the  continuance of a
Default or Event of Default, the Agent may notify any securities intermediary or
depository  to  liquidate  the  applicable  Securities  Account  or any  related
investment property maintained or held thereby and remit the proceeds thereof to
Agent's Account.

     5. REPRESENTATIONS AND WARRANTIES.

         In order to induce  the  Lender  Group to enter  into  this  Agreement,
Borrower,  makes the  following  representations  and  warranties  to the Lender
Group,  which shall be true, correct and complete on and as of the Closing Date,
as though  made on and as of the  Closing  Date  (except to the extent that such
representations  and warranties  relate solely to an earlier date, in which case
such  representations  and warranties shall have been true and correct on and as



of such earlier date), and such representations and warranties shall survive the
execution and delivery of this Agreement:

         5.1 No Encumbrances.  Borrower has good and  indefeasible  title to the

Inventory,  including  Hydrocarbon  products (except for Hydrocarbon products in
transit), other than the locations identified on Schedules 5.3 and 5.22. Each of
Schedule  5.3 and  5.22  contains  a true,  correct  and  complete  list of each

Shares or any security convertible into or exchangeable for any of its Shares.

               (c)  Except  as set forth in  Schedule  5.6(c),  Borrower  has no
Subsidiaries  or other ownership  interest  (including the right to share in the

which it is a party have been duly  authorized  by all  necessary  action on the
part of Borrower.

               (b) The execution,  delivery and  performance by Borrower of this
Agreement  and the other Loan  Documents  to which it is a party do not and will

financing statements,  security notices and Mortgages,  the execution,  delivery
and  performance  by Borrower of this  Agreement and the other Loan Documents to

               (d) Borrower has duly executed and delivered  this Agreement and,
on the Closing Date,  each other Loan Document to which  Borrower is a party and
each other document contemplated hereby and thereby to which Borrower is a party
will be duly and validly executed by Borrower.  This Agreement constitutes,  and
each other Loan  Document to which  Borrower is a party and each other  document
contemplated  hereby and thereby to which Borrower is a party, when executed and
delivered by Borrower will constitute, a legally valid and binding obligation of
Borrower,  enforceable  against Borrower in accordance with its terms, except as
enforcement may be limited by equitable principles or by bankruptcy, insolvency,
reorganization,  moratorium or similar laws  relating to or limiting  creditors'
rights generally.

               (e) On and  after the  Closing  Date,  Agent  will have a validly
created,  first priority  perfected  (except for certain real property  filings)
Lien on all of the Collateral, subject only to Permitted Liens.


         5.8  Litigation.  Other than those  matters  disclosed on Schedule 5.8,
there are no actions,  suits or proceedings pending or, to the best knowledge of
Borrower,  threatened against Borrower except for matters that are fully covered
by insurance (subject to customary deductibles).

         5.9 No Material Adverse Change.  All financial  statements  relating to
Borrower  that have been  delivered  by Borrower  to the Lender  Group have been
prepared in  accordance  with GAAP (except,  in the case of unaudited  financial
statements,  for the lack of  footnotes  and being  subject  to  year-end  audit
adjustments) and present fairly in all material respects,  Borrower's  financial
condition as of the date thereof and results of  operations  for the period then
ended. There has not been a Material Adverse Change.

               (a) Borrower is Solvent.

               (b) No transfer  of  property  is being made by  Borrower  and no

hinder, delay or defraud either present or future creditors of Borrower.

         5.11 Employee Benefits. Borrower does not maintain or contribute to any
Benefit  Plan.  Borrower  has  satisfied  the minimum  funding  standards of the
Canadian Employee Benefit Laws and any other applicable law relating to employee
benefits  with  respect  to  each  Benefit  Plan to  which  it is  obligated  to
contribute.  No event  has  occurred  with  respect  to such  Benefit  Plan that
reasonably could be expected to result in a Material Adverse Change. Borrower is
not  required to provide  security to any Benefit Plan under  Canadian  Employee
Benefit Laws.

         5.12 Environmental Condition. Except as set forth on Schedule 5.12, (a)
to Borrower's  knowledge,  no assets of Borrower have ever been used by Borrower
or by previous  owners or operators  in the  disposal of, or to produce,  store,
handle,  treat,  release  or  transport,  any  Hazardous  Materials,  where such
production,  storage,  handling,  treatment,  release or  transportation  was in
violation,  in any material  respect,  of applicable  Environmental  Law, (b) to
Borrower's  knowledge,  no  properties  or  assets  of  Borrower  have ever been
designated  or  identified in any manner  pursuant to  environmental  protection

notice  that a Lien  arising  under any  Environmental  Law has  attached to any
revenues or to any Real Property  owned or operated by Borrower and (d) Borrower

Authority  concerning  any  action or  omission  by  Borrower  resulting  in the
releasing or disposing of Hazardous Materials into the environment.

         5.13 Brokerage Fees. Other than GCF and its Affiliates, neither Abraxas
nor Borrower  has  utilized  the services of any broker or finder in  connection
with Borrower's  obtaining financing from the Lender Group under this Agreement,



and, other than GCF and its Affiliates,  no brokerage commission or finders' fee
is payable by Borrower in connection herewith.

         5.14  Intellectual  Property.  Borrower owns, or holds licenses in, all
trademarks,  trade names,  copyrights,  patents, patent rights and licenses that
are  necessary to the conduct of its business as currently  conducted.  Attached
hereto as Schedule 5.14 is a true,  correct and complete listing of all material
patents, patent applications, trademarks, trademark applications, copyrights and
copyright  registrations  as to which  Borrower  is the  owner  or an  exclusive
licensee.

         5.15 Leases.  Borrower enjoys peaceful and undisturbed possession under
all leases  material to the  business of Borrower  and to which it is a party or
under which it is operating.  All of such leases are valid and subsisting and no
material  default by  Borrower  exists  under any of them.  There are no leases,
subleases,  contracts or other operating  agreements with respect to any Oil and
Gas Property that allocate  operating expenses to Borrower in excess of Borrower
working  interest of record in the  particular  Oil and Gas Property  subject to
such lease, the sublease, contract or other operating agreement.

         5.16  DDAs.  Set forth on  Schedule  5.16 are all of  Borrower's  DDAs,
including,  with  respect to each  depository  (i) the name and  address of such
depository  and (ii) the account  numbers of the accounts  maintained  with such
depository.

         5.17  Compliance  with the Law.  Borrower  has not  violated any law or
failed to obtain any material license,  permit, franchise or other authorization
from any  Governmental  Authority  necessary for the ownership of any of its Oil
and Gas Properties or the conduct of its business. The Oil and Gas Properties of
Borrower (and assets and properties  utilized  therewith) have been  maintained,
operated  and  developed  in a good and  workmanlike  manner and in  substantial
conformity with all applicable laws and all rules, regulations and orders of all
Governmental  Authorities having jurisdiction and in substantial conformity with
the provisions of all leases,  subleases or other contracts comprising a part of
the Hydrocarbon  Interests and other contracts and agreements  forming a part of
such Oil and Gas Properties;  specifically in this connection, (i) except as set
forth on Schedule 5.17,  after the Closing Date, no such Oil and Gas Property is
subject  to having  allowable  production  reduced  below  the full and  regular
allowable  production  (including the maximum permissible  tolerance) because of
any  overproduction  (whether or not the same was permissible at the time) prior
to the Closing Date and (ii) none of the wells comprising a part of such Oil and
Gas Properties (or assets and  properties  utilized  therewith) is deviated from
the vertical by more than the maximum permitted by applicable laws, regulations,
rules and orders of any Governmental Authority.

         5.18 Complete  Disclosure.  All factual  information (taken as a whole)
furnished  by or on  behalf  of  Borrower  in  writing  to Agent  or any  Lender
(including  all  information  contained in the schedules  hereto or in the other
Loan Documents) for purposes of or in connection with this Agreement,  the other
Loan Documents or any transaction  contemplated  herein or therein does not, and
all other such factual  information (taken as a whole) hereafter furnished by or
on behalf of  Borrower in writing to Agent or any Lender will not on the date as
of which such information is dated or certified  contain any untrue statement of



a material fact, and does not or will not on such date, as the case may be, omit
to state any material fact necessary to make such information (taken as a whole)
not  misleading  in  any  material   respect  at  such  time  in  light  of  the
circumstances under which such information was provided. As of the date on which
any  Projections  are  delivered  to  Agent,  such  Projections  will  represent
Borrower's  good faith best estimate of its future  performance  for the periods
covered thereby.

         5.19  Indebtedness.  Set forth on Schedule  5.19 is a true and complete
list of all  Indebtedness  of Borrower  which will be outstanding on the Closing
Date (after giving effect to the Loan),  and Schedule 5.19  accurately  reflects
the aggregate  principal  amount of such  Indebtedness  and the principal  terms
thereof.

         5.20 Oil and Gas Imbalances. Except as set forth on Schedule 5.20, on a
net  basis  there  are  not gas  imbalances,  take-or-pay  oil and gas or  other
prepayments  with respect to the Oil and Gas  Properties of Borrower which would
require  Borrower either to make cash settlements for such production or deliver
Hydrocarbons  produced  from such Oil and Gas  Properties  at some  future  time
without then or  thereafter  receiving  full  payments  therefor  exceeding  two
percent (2%) of the current  monthly  production of oil and gas from the Oil and
Gas Properties of Borrower in the aggregate.

         5.21 Hedging  Agreements.  Schedule 5.21 sets forth a true and complete
list of all  Hedging  Agreements  (including  commodity  price swap  agreements,
forward  agreements  or  contracts  of sale which  provide  for  prepayment  for
deferred shipment or delivery of Hydrocarbons or other commodities) of Borrower,
the  material  terms  thereof   (including  the  type,  term,   effective  date,
termination date and notional amounts or volumes), all credit support agreements
relating   thereto   (including  any  margin   required  or  supplied)  and  the
counterparty to each such agreement.

         5.22 Location of Real Property and Leased Premises.

               (a) (i) Part A of Schedule  5.22 lists  completely  and correctly
all Real Property (other than Oil and Gas  Properties)  owned in fee by Borrower
and the  respective  addresses  thereof,  (ii)  Part B of  Schedule  5.22  lists
completely and correctly all Real Property  (other than Oil and Gas  Properties)
leased by  Borrower  and the  respective  addresses  thereof and (iii) Part C of
Schedule  5.22 lists  completely  and  correctly  all Oil and Gas  Properties of
Borrower  with a PV-10 of at least  U.S.  $50,000,  whether  leased  or owned by
Borrower,  and the respective legal  descriptions,  addresses (if any), counties
and states thereof.

               (b)  Borrower  has a  valid  leasehold  interest  in  each of the
respective  leases  described on Schedule 5.22 and such schedule sets forth with
respect to each such lease, the commencement  date,  termination  date,  renewal
options (if any) and annual base rents. Each such lease is valid and enforceable
in accordance  with its terms in all material  respects and is in full force and
effect.  No  consent  or  approval  of any  landlord  or  other  third  party in
connection  with any such  lease is  necessary  for  Borrower  to enter into and
execute  the Loan  Documents  to which it is a  party,  except  as set  forth on
Schedule  5.22.  Borrower  is not in default of its  obligations  under any such
lease and, to the knowledge of Borrower,  no other party to any such lease is in
default of its obligations thereunder,  and neither Borrower nor any other party



to any such lease has at any time  delivered  or received  any notice of default
which remains uncured under any such lease and no event has occurred which, with
the giving of notice or the passage of time or both,  would constitute a default
under any such lease.

               (c) Borrower has good and defensible  title to all of its Oil and
Gas Properties set forth on Schedule 5.22 which  constitute  Real Property,  and
good  and  indefeasible  title  to all of  its  Oil  and  Gas  Properties  which
constitute  personal property,  except for (i) such imperfections of title which
do not in the aggregate materially detract from the value thereof to, or the use
thereof in, the business of Borrower and (ii) Permitted  Liens.  The quantum and
nature of the interest of Borrower in and to the Oil and Gas  Properties  as set
forth in the Initial  Reserve Report includes the entire interest of Borrower in
such Oil and Gas Properties as of the date of the Initial Reserve Report and are
complete  and  accurate in all  material  respects as of the date of the Initial
Reserve Report;  and there are no "back-in" or "reversionary"  interests held by
third parties which could materially reduce the interest of Borrower in such Oil
and Gas Properties  except as expressly set forth in the Initial Reserve Report.
The  ownership  of the Oil and  Gas  Properties  by  Borrower  shall  not in any
material respect  obligate any Borrower to bear the costs and expenses  relating
to the maintenance,  development or operations of each such Oil and Gas Property
in an amount in excess of the working interest of record of Borrower in each Oil
and Gas Property set forth in the Initial Reserve Report.

               (d) Borrower marketing, gathering, transportation, processing and
treating  facilities  and  equipment,  together with any  marketing,  gathering,
transportation,  processing and treating contract in effect between and/or among
Borrower and any other  Person,  are  sufficient to gather,  transport,  process
and/or treat reasonably  anticipated  volumes of production of Hydrocarbons from
the Oil and Gas Properties of Borrower.

         5.23 Material  Contracts.  Set forth on Schedule 5.24 is a complete and
accurate  list of all Material  Contracts  of Borrower,  showing the parties and
subject  matter  thereof and amendments  and  modifications  thereto.  Each such
Material  Contract  (i) is in full  force and  effect  and is  binding  upon and
enforceable  against  Borrower  thereto and, to the  knowledge of Borrower,  all
other parties thereto in accordance with its terms,  (ii) has not been otherwise
amended or  modified  and (iii) is not in default  due to the action of Borrower
or, to the knowledge of Borrower, any other party thereto.

         5.24  Permits,  Etc.  Borrower  has,  and is in  compliance  with,  all
permits, licenses,  authorizations,  approvals,  entitlements and accreditations
required for Borrower lawfully to own, lease,  manage or operate, or to acquire,
each  business  and the  Real  Property  currently  owned,  leased,  managed  or
operated,  or to be acquired,  by Borrower,  except for such permits,  licenses,
authorizations,  approvals, entitlements and accreditations the absence of which
could not  reasonably  be expected to result in a Material  Adverse  Change.  No
condition  exists or event has occurred  which,  in itself or with the giving of
notice or lapse of time or both,  would  result in the  suspension,  revocation,
impairment,   forfeiture   or   non-renewal   of  any  such   permit,   license,
authorization,  approval,  entitlement  or  accreditation,  and,  to  Borrower's
knowledge, there is no claim that any thereof is not in full force and effect.


         5.25 Employee and Labor Matters.  Except as set forth on Schedule 5.26,
there is (a) no unfair  labor  practice  complaint  pending  or,  to  Borrower's
knowledge,  threatened against Borrower before any Governmental Authority and no
grievance or arbitration proceeding pending or threatened against Borrower which
arises out of or under any collective bargaining agreement, (b) no strike, labor
dispute,  slowdown,  stoppage or similar action or grievance  pending or, to the
knowledge  of   Borrower,   threatened   against   Borrower  and  (c)  no  union
representation  question  existing with respect to the employees of Borrower and
no union  organizing  activity taking place with respect to any of the employees
of any of them. The hours worked and payments made to employees of Borrower have
not been in violation of the applicable Canadian provincial employment standards
legislation or any other applicable legal  requirements.  All material  payments
due from Borrower on account of workers compensation,  wages and employee health
and  welfare  insurance  and  other  benefits  have been  paid or  accrued  as a
liability on the books of Borrower.

         5.26 Bonds and  Insurance.  Schedule  5.27  contains  an  accurate  and
complete  description  of all  performance  bonds  related to  operations  on or
pertaining to the Oil and Gas  Properties  of Borrower  Parties and all material
policies of insurance owned or held by Borrower Parties.  Except as set forth on
Schedule 5.27, all such policies are in full force and effect, all premiums with
respect  thereto  covering all periods up to and including the Closing Date have
been paid, and no notice of  cancellation  or termination has been received with
respect to any such  policy.  Such bonds and  policies  (i) are  sufficient  for
compliance with all  requirements of law and of all agreements to which Borrower
is a party, (ii) are valid,  outstanding and enforceable policies, (iii) provide
adequate  coverage in at least such amounts and against at least such risks (but
including  in any  event  public  liability)  as are  required  by  Governmental
Authorities and/or usually insured or bonded against in the same general area by
companies  engaged  in the  same  or a  similar  business  for  the  assets  and
operations  of the Borrower  Parties,  (iv) will remain in full force and effect
through the  respective  dates set forth on Schedule 5.27 without the payment of
additional premiums except as set forth on Schedule 5.27 and (v) will not in any
way be  affected  by, or  terminate  or lapse by  reason  of,  the  transactions
contemplated  by this  Agreement.  Borrower  has not been  refused  any bonds or
insurance  with respect to its assets or  operations,  nor has its coverage been
limited below usual and customary bond or policy limits,  by any bonding company
or  insurance  carrier to which it has applied for any such bond or insurance or
with which it has carried insurance during the last three years.

         5.27 Nature of Business.  Borrower is not engaged in any business other
than the Oil and Gas Business within Canada.

               (b) Cause to be done all things necessary to preserve and keep in
good repair, working order and efficiency all the Oil and Gas Properties of each
Borrower Party and other material  assets  including,  without  limitation,  all

processing assets and, from time to time, will make all the reasonably necessary
repairs, renewals and replacements so that at all times the state and conditions
of such Oil and Gas Properties and other material assets will be fully preserved
and  maintained,  except  to the  extent a portion  of such  assets is no longer
capable of producing Hydrocarbons in economically reasonable amounts.

               (c) Promptly (i) pay and/or  discharge or cause to be paid and/or
discharged,  all rentals,  royalties,  expenses, taxes and Indebtedness accruing

economically reasonable amounts.

               (d)  Operate  its Oil  and  Gas  Properties  and  other  material
properties or cause or make  reasonable and customary  efforts to cause such Oil
and Gas Properties and other material  properties to be operated on a continuous

compliance in all material respects with all material laws.

               (e) Operate and produce,  as a reasonably  prudent operator,  the
Oil and Gas Properties of Borrower  Parties in accordance with good  engineering
practices  and the  following  requirements:  (i)  the  amount  of  Hydrocarbons
produced  from any well  shall  not  exceed  in any  month  the lower of (A) the
maximum  amount that such well is capable of producing at its maximum  efficient
rate of flow and (B) the  respective  allowable  rate of flow  under  applicable
orders,  rules,  regulations  or laws, if any;  (ii) the amount of  Hydrocarbons
produced  from  Borrower'  Parties  wells shall be  sufficient  to prevent a net
migration of  Hydrocarbons  from the  reservoirs  to which  Proved  Reserves are
attributed;  and (iii) subject to field rules  established  by any  Governmental
Authority having or asserting jurisdiction,  the amount of Hydrocarbons produced
from  Borrower'  Parties wells shall be equitable and ratable,  based on factors

               (f) To the extent the  interests in Oil and Gas  Properties  of a
Borrower Party (other than working  interests of record) are operated by Persons
other than a Borrower Party,  Borrower shall cause any owner or operator of such
Oil and Gas Properties to comply with this Section 6.4; provided,  however, that
it shall not be a breach of this Section 6.4 if such owners or operators are not
in  compliance  with this  Section 6.4 on Oil and Gas  Properties  of a Borrower
Party with an aggregate  PV-10 for all such Oil and Gas  Properties of less than
U.S. $100,000.

         6.5 Taxes.

         Cause  all  assessments,   remittances,  source  deductions  and  taxes

except to the extent that the validity of such Tax Payment  shall be the subject
of a Permitted Protest.  Each Borrower Party will make timely payment or deposit
of all Tax Payments  required of it by  Applicable  Laws,  including  those laws
concerning local, municipal, provincial and federal income taxes, and will, upon
request,  furnish Agent with proof  satisfactory  to Agent  indicating that such
Borrower  Party has made such Tax Payments or deposits.  Borrower  shall deliver
satisfactory evidence of payment of applicable excise taxes in each jurisdiction
in which a Borrower Party is required to pay any such excise tax.

         6.6 Insurance.

               (a) At Borrower's  expense,  maintain  insurance  respecting  its
assets wherever located,  covering loss or damage by fire, theft,  explosion and
all other hazards and risks as ordinarily  are insured  against by other Persons
engaged in the same or similar  businesses.  Borrower also shall maintain public
liability  insurance,  as well as insurance  against  larceny,  embezzlement and
criminal misappropriation to the extent Borrower maintains such insurance on the
Closing Date or is otherwise required by Agent, in its reasonable discretion, to
maintain  such  insurance  after the  Closing  Date to the extent  the  premiums
related thereto are not at levels commercially  unreasonable.  All such policies
of insurance  shall be in such amounts and with such insurance  companies as are



reasonably  satisfactory  to Agent.  Borrower  shall deliver  copies of all such
policies to Agent with a satisfactory  lender's loss payable  endorsement naming
Agent as first loss payee. Each policy of insurance or endorsement shall contain
a Section  requiring  the insurer to give not less than 30 days'  prior  written
notice  to Agent in the  event of  cancellation  of the  policy  for any  reason
whatsoever.  During the period of the drilling of wells and the  construction of
any other  improvements  comprising a part of the Oil and Gas  Properties of any
Borrower Party,  Borrower shall, or, as applicable,  shall cause its contractors
or  subcontractors  to,  obtain and maintain well control  insurance  (including
coverage for costs and redrilling) and builder's risk insurance,  as applicable,
in  such  form  and  amounts  as is  customary  in  the  industry  and  worker's
compensation  insurance  covering all Persons  employed by any Borrower Party or
its agents or  subcontractors  of any tier in connection  with any  construction
affecting such Oil and Gas Properties, including, without limitation, all agents
and  employees of any Borrower  Party and such Borrower  Party's  subcontractors
with respect to whom death or bodily injury claims could be asserted against any
Borrower Party.

               (b) Borrower  shall give Agent prompt  notice of any loss covered
by  such  insurance.  So  long  as no  Event  of  Default  has  occurred  and is
continuing,  Borrower  shall  have the  right  to  adjust  losses  of up to U.S.
$100,000 in the  aggregate.  If an Event of Default  shall have  occurred and is
continuing,  Agent shall have the exclusive  right to adjust any losses  payable
under any such  insurance  policies,  and in any event shall have the  exclusive
right to adjust all losses in excess of U.S.  $100,000 in the aggregate  without
any liability to any Borrower  Party  whatsoever in respect of such  adjustments
absent Agent's gross negligence or willful misconduct as finally determined by a
court of  competent  jurisdiction.  Any monies  received as payment for any loss
under any  insurance  policy  mentioned  above (other than  liability  insurance
policies) or as payment of any award or compensation  for condemnation or taking
by eminent  domain,  (i) in an amount not to exceed U.S.  $600,000  per year and
U.S. $1,800,000 in the aggregate over the term of this Agreement, shall, so long
as no Default or Event of Default has  occurred  and is  continuing,  be paid to
Borrower for repair,  replacement or restoration of the assets to which the loss
relates and (ii)  relating  to other  properties  or in excess of such  amounts,
shall be paid over to Agent to be applied at the option of the Required  Lenders
either to the  prepayment of the  Obligations  or shall be disbursed to Borrower
under staged payment terms  reasonably  satisfactory to the Required Lenders for
application  to the cost of repairs,  replacements,  or  restorations.  Any such
repairs,  replacements,  or  restorations  shall  be  effected  with  reasonable
promptness  and shall be of a value at least  equal to the value of the items of
property destroyed prior to such damage or destruction.

               (c) No Borrower Party will take out separate insurance concurrent
in form or contributing in the event of loss with that required to be maintained
under this Section 6.6,  unless Agent is included  thereon as named insured with
the loss payable to the Agent under a lender's loss payable  endorsement  or its
equivalent.  Borrower  immediately  shall notify Agent  whenever  such  separate
insurance is taken out,  specifying the insurer  thereunder and full particulars
as to the policies  evidencing  the same,  and copies of such policies  promptly
shall be provided to Agent.


         6.7 Location of Inventory and Equipment. Keep the Equipment only at the
locations identified on Schedule 5.3 and 5.22; provided,  however, that Borrower
may amend  Schedule 5.3 so long as such  amendment  occurs by written  notice to
Agent not less  than 30 days  prior to the date on which  Equipment  is moved to
such new location,  so long as such new location is within  Canada,  and so long
as, at the time of such  written  notification,  Borrower  provides any personal
property registry or other financing  statements or fixture filings necessary to
perfect and continue perfected Agent's Liens on such assets and also provides to
Agent a Collateral Access Agreement.

         6.8  Compliance  with  Laws.   Comply  with  the  requirements  of  all
Applicable Laws,  rules,  regulations and orders of any Governmental  Authority,
and other than laws,  rules,  regulations  and  orders the  non-compliance  with
which,  individually  or in the  aggregate,  would not result in and  reasonably
could not be expected to result in a Material Adverse Change.

         6.9 Leases.  Pay when due all rents and other amounts payable under any
lease to which any Borrower  Party is a party or by which any of the  properties
and assets of a Borrower  Party are bound,  unless such payments are the subject
of a Permitted Protest.

         6.10  Brokerage  Commissions.  Pay any and all brokerage  commission or
finders' fees incurred in connection with or as a result of Borrower's obtaining
financing  from the Lender  Group  under  this  Agreement.  Borrower  agrees and
acknowledges  that payment of all such  brokerage  commissions  or finders' fees
shall be the sole responsibility of Borrower,  and Borrower agrees to indemnify,
defend and hold Agent and the Lender Group  harmless  from and against any claim
of any broker or finder arising out of Borrower's  obtaining  financing from the
Lender Group under this Agreement.

         6.11 Existence. At all times preserve and keep in full force and effect

franchises material to each Borrower Party's businesses.

         6.12  Environmental.  (a) Keep any property either owned or operated by

evidenced by such  Environmental  Liens, (b) comply,  in all material  respects,
with  Environmental  Laws and provide to Agent  documentation of such compliance
which Agent reasonably  requests,  (c) promptly notify Agent of any release of a
Hazardous  Material in a quantity which is in violation of any Environmental Law
from or onto  property  owned or  operated  by any  Borrower  Party and take any
Remedial  Actions  required  to abate  said  release or  otherwise  to come into
compliance with applicable Environmental Law and (d) promptly provide Agent with
written notice within 10 days of the receipt of any of the following: (i) notice
that an  Environmental  Lien has been filed  against any of the real or personal
property of any Borrower Party, (ii) commencement of any Environmental Action or
notice that an Environmental Action will be filed against any Borrower Party and
(iii)  notice of a  violation,  citation,  or other  administrative  order which
reasonably could be expected to result in a Material Adverse Change.


         6.13 Disclosure Updates. Promptly and in no event later than 5 Business
Days  after  obtaining  knowledge  thereof,  (a)  notify  Agent  if any  written
information,  exhibit or report  furnished  to the Lender  Group  contained  any
untrue  statement  of a  material  fact or omitted  to state any  material  fact
necessary to make the  statements  contained  therein not misleading in light of
the  circumstances in which made and (b) correct any defect or error that may be
discovered therein or in any Loan Document or in the execution, acknowledgement,
filing or recordation thereof.

         6.14  After  Acquired  Properties.  With  respect  to any  Oil  and Gas
Property of Borrower with a PV-10 of at least U.S.  $50,000  acquired  after the
Closing Date by Borrower or any discovery  and/or  confirmation of the existence
of  Hydrocarbons  in any property owned or leased by Borrower,  promptly (and in
any event within 30 days after the acquisition thereof):  execute and deliver to
Agent such  amendments to the  Mortgages or such other  documents as Agent shall
deem  necessary or  advisable  to grant to Agent,  for the benefit of the Lender
Group, a perfected  first  priority Lien on such Oil and Gas Property;  take all
actions  necessary  or  advisable  to cause  such Lien to be duly  perfected  in
accordance with all applicable law, including, without limitation, the filing of
Mortgages or personal  property  registry or other financing  statements in such
jurisdictions  as may be  requested  by Agent;  and (C)  deliver to Agent  title
opinions and/or legal opinions relating to the matters described in Sections (A)
and (B)  immediately  preceding,  which opinions shall be in form and substance,
and from counsel, reasonably satisfactory to Agent.

         6.15 Protection  Against  Drainage.  To the extent that the Oil and Gas
Properties of any Borrower Party (i) are operated by a Borrower Party,  Borrower
Parties shall act as a reasonably  prudent operator in an effort to identify and
prevent the  occurrence  of any drainage of  Hydrocarbons  from such Oil and Gas
Properties and (ii) are not operated by a Borrower Party, Borrower Parties shall
utilize their property and contractual  rights as a reasonably  prudent owner in
an effort to identify and prevent the occurrence of any drainage of Hydrocarbons
from such Oil and Gas Properties.

         6.16 Additional  Collateral Reviews.  Borrower shall, from time to time
upon the reasonable  request of Agent, take such actions and execute and deliver
such documents and instruments as Agent, as applicable,  shall require to ensure
that Agent  shall,  at all  times,  have  received  satisfactory  title  reviews
(including,  if requested,  supplemental or new title opinions addressed to it),
which title opinions shall be in form and substance acceptable to Agent in their
sole  discretions  and shall  include  opinions  regarding the before payout and

maintain in effect one or more  Commodities  Hedging  Agreements with respect to
its Hydrocarbon  production  with one or more  counterparties  rated  investment
grade by Moody's and Standard & Poor's,  or the  equivalent  by a rating  agency
acceptable to Agent or with a counterparty  otherwise  reasonably  acceptable to
Agent.  The  aggregate   notional  volumes  of  Hydrocarbons   covered  by  such
Commodities  Hedging  Agreements shall constitute not less than 25% and not more
than 75% of the Borrower's Parties' aggregate estimated  Hydrocarbon  production



volumes on an mcf equivalent  basis (where one barrel of oil is equal to six mcf
of gas) for the succeeding  six calendar  months on a rolling six calendar month
basis for such period from Oil and Gas Properties classified as Proved Developed
Producing  Reserves as of the date of the most recent Reserve  Report  delivered
pursuant  to Section  6.2(e)  plus the  estimated  production  from  anticipated
drilling by Borrower  Parties during such succeeding six months.  Borrower shall
use such Commodities  Hedging Agreements solely as a part of its normal business
operations as a risk management  strategy and/or hedge against changes resulting
from market conditions related to the oil and gas operations of Borrower Parties
and not as a means to speculate for investment  purposes on trends and shifts in
financial or commodities markets.

and conditions of such  refinancings,  renewals or extensions do not, in Agent's
judgment,  materially  impair the prospects of repayment of the  Obligations  by
Borrower  or   materially   impair   Borrower's   creditworthiness,   (ii)  such
refinancings,  renewals  or  extensions  do not  result  in an  increase  in the
principal  amount of, or  interest  rate with  respect to, the  Indebtedness  so
refinanced, renewed or extended, (iii) such refinancings, renewals or extensions
do  not  result  in a  shortening  of  the  average  weighted  maturity  of  the

conditions that, taken as a whole, are materially more burdensome or restrictive
to Borrower,  (iv) if the Indebtedness  that is refinanced,  renewed or extended
was  subordinated  in right of  payment to the  Obligations,  then the terms and
conditions of the refinancing,  renewal or extension  Indebtedness  must include

Group as those that were  applicable  to the  refinanced,  renewed  or  extended
Indebtedness  and (v) if the Permitted Liens securing the  Indebtedness  that is
refinanced,  renewed or extended was subordinated to the Liens of Agent securing
the Obligations,  then the terms and conditions of such refinancing,  renewal or

Subsidiaries,  as the case may be, in order to  provide  security  for  workers'
compensation  claims,  payment  obligations in connection with self-insurance or
similar  requirements  in the ordinary  course of  business,  to the extent such
letters  of  credit  are  unsecured  and  subordinated,  in form  and  substance
satisfactory to Agent, to the Obligations; and

               (j)  other  unsecured  Indebtedness  of  Borrower  or  any of its

of shares of common stock to  employees,  officers and  directors of Borrower in
the ordinary course of business), whether in a public or private transaction and
whether  as an  initial  or  follow-on  issuance,  unless  such  issuance  is of
Qualified Stock and all of the net proceeds from such issuance are first applied
to satisfy any Obligations then outstanding.

               (b)  Borrower  agrees  that it will not enter into any  contract,
instrument,  agreement or other  arrangement  which conflicts with, or otherwise
restricts, the obligations of Borrower under this Section 7.24.


     8. EVENTS OF DEFAULT.

         Any one or more of the  following  events shall  constitute an event of
default  (other than any event  described in Sections  8.2 or 8.11,  which shall
constitute  an event of default  upon  notice to  Borrower  by Agent of any such
event) (each, an "Event of Default") under this Agreement:


         8.1 If Borrower fails to pay when due and payable, or when declared due

Codes,  would have  accrued on such  amounts),  fees and  charges due the Lender
Group,  reimbursement  of Lender Group  Expenses or other  amounts  constituting
Obligations);

         8.2 (i) If  Borrower  fails  to  perform,  keep or  observe  any  term,

6.8 and 6.15 of this  Agreement,  or  comparable  provisions  of the other  Loan
Documents,  and such failure  continues for 15 days,  (ii) if Borrower  fails to
perform, keep, or observe any term, provision,  condition, covenant or agreement
contained in Sections  6.2,  6.3, 6.7 and 6.9 of this  Agreement,  or comparable
provisions of the other Loan Documents, and such failure continues for 5 days or
(iii) if Borrower  otherwise  fails to perform,  keep or observe any other term,
provision,  condition,  covenant or agreement  contained in this Agreement or in
any of the other Loan Documents;


         8.3 If any material  portion of a Borrower  Party's assets is attached,

possession of any third Person;

         8.4 If an Insolvency Proceeding is commenced by a Borrower Party;

         8.5 If an Insolvency  Proceeding is commenced  against a Borrower Party

institution  of  such  Insolvency   Proceeding  against  it,  (b)  the  petition
commencing  the  Insolvency  Proceeding  is not  timely  controverted,  (c)  the
petition  commencing  the  Insolvency  Proceeding  is not  dismissed  within  45
calendar days of the date of the filing thereof; provided, however, that, during
the pendency of such period,  Agent  (including  any  successor  agent) and each
other member of the Lender Group shall be relieved of their obligations (if any)
to  extend  credit  hereunder,  (d) an  interim  trustee  is  appointed  to take
possession of all or any substantial  portion of the properties or assets of, or
to operate all or any  substantial  portion of the business of, a Borrower Party
or (e) an order for relief shall have been entered therein;

         8.6 If a Borrower Party is enjoined, restrained or in any way prevented
by court  order from  continuing  to  conduct  all or any  material  part of its
business affairs;

         8.7 If a notice of Lien,  levy or  assessment  is filed of record  with
respect to (a) any of  Borrower's  assets  (other  than their  Proved  Developed
Producing  Reserves)  in an amount or with  respect  to assets in excess of U.S.
$100,000, or (b) any of Borrower Party's Proved Developed Producing Reserves, by
the Province of Alberta or any department, agency or instrumentality thereof, or
by any state,  county,  municipal  or  governmental  agency , or if any taxes or
debts owing at any time hereafter to any one or more of such entities  becomes a
Lien,  whether  choate or otherwise,  upon (x) any of a Borrower  Party's assets
(other than their Proved  Developed  Producing  Reserves),  in an amount or with
respect to assets in excess of U.S.  $100,000  or (y) any of a Borrower  Party's
Proved  Developed  Producing  Reserves,  and the  same is not paid  before  such
payment is delinquent;

         8.8 If a judgment  or other  claim in excess of U.S.  $100,000  (to the
extent not bonded or insured by a bonding or  insurance  company  acceptable  to
Agent) in the aggregate  becomes a Lien or encumbrance upon any material portion
of a Borrower Party's assets;

         8.9 If there is a continuing  default  under any material  agreement to
which a  Borrower  Party is a party  and such  default  (a)  occurs at the final
maturity of the  obligations  thereunder  or (b) results in a right by the other
party thereto,  irrespective of whether exercised, to accelerate the maturity of
the obligations of a Borrower Party thereunder,  to terminate such agreement, or
to refuse  to renew  such  agreement  pursuant  to an  automatic  renewal  right
therein;

         8.10 If Borrower makes any payment on account of Indebtedness  that has

Obligations,  except to the extent such payment is permitted by the terms of the
subordination provisions applicable to such Indebtedness and except as permitted
under Section 7.8;


         8.11 If any material  misstatement or  misrepresentation  exists now or

member of the  Lender  Group by  Borrower  or any  officer,  employee,  agent or
director of a Borrower Party;

         8.12 If there is a loss,  suspension  or  revocation  of, or failure to
renew, any license or permit now held or hereafter  acquired by a Borrower Party

expected to have a Material Adverse Change;

         8.13 If this Agreement, any Collateral Document or any other agreement,
instrument or document that purports to create a Lien in favor of Agent, for the
benefit of the Lender  Group,  shall for any  reason,  fail or cease to create a
valid and perfected and,  except to the extent  permitted by the terms hereof or
thereof,  first priority Lien on or security interest in the Collateral  covered
hereby or thereby; or

         8.14  Any  provision  of any  Loan  Document  shall at any time for any
reason be declared by a court of competent  jurisdiction  to be null and void or
invalid or  unenforceable,  or the validity or  enforceability  thereof shall be
contested in a proceeding  by  Borrower,  or a proceeding  shall be commenced by
Borrower,  or by any Governmental  Authority having  jurisdiction over Borrower,
seeking to establish the  invalidity or  unenforceability  thereof,  or Borrower
shall deny that it has any liability or obligation purported to be created under
any Loan Document.

         8.15 If any Borrower Party fails to perform, keep, or observe any term,
provision,  condition,  covenant or agreement contained in clause (h) of Section

     9. THE LENDER GROUP'S RIGHTS AND REMEDIES.

         9.1  Rights  and  Remedies.   Upon  the  occurrence,   and  during  the
continuation,  of an Unmatured Default or Event of Default, the Required Lenders
(at their election but without notice of their election and without  demand) may
authorize and instruct Agent to do any one or more of the following on behalf of
the Lender  Group (and  Agent,  acting  upon the  instructions  of the  Required
Lenders,  shall do the same on behalf  of the  Lender  Group),  all of which are
authorized by Borrower:

               (a) Declare all Obligations, whether evidenced by this Agreement,
by any of the other Loan Documents or otherwise, immediately due and payable;

               (b)  Cease  advancing  money or  extending  credit  to or for the
benefit of Borrower  under this  Agreement,  under any of the Loan  Documents or
under any other agreement between Borrower and the Lender Group;

               (c) Terminate  this Agreement and any of the other Loan Documents
as to any future  liability  or  obligation  of the Lender  Group,  but  without
affecting any of the Liens of Agent in the Collateral and without  affecting the
Obligations;

               (d) Exercise any of its remedies under the Debenture;


               (e)  Without  notice to Borrower  (such  notice  being  expressly
waived),  and without constituting a retention of any collateral in satisfaction
of an obligation,  set off and apply to the Obligations any and all (i) balances
and deposits of Borrower  held by the Lender Group or (ii)  Indebtedness  at any
time owing to or for the credit or the  account of  Borrower  held by the Lender
Group;

               (f) Hold, as cash  collateral,  any and all balances and deposits
of Borrower held by the Lender Group,  to secure the full and final repayment of
all of the  Obligations  and apply,  to the extent  permitted by applicable law,
such cash collateral to repay the Obligations;

               (g) Without  limitation or exclusion to any other rights  granted
hereunder,  Agent and the Lender  Group shall have all other rights and remedies
available at law or in equity or pursuant to any other Loan Document.

         9.2  Remedies  Cumulative.  The  rights and  remedies  of Agent and the
Lender  Group  under  this  Agreement,  the other Loan  Documents  and all other
agreements shall be cumulative.  Agent and the Lender Group shall have all other
rights and remedies not inconsistent with this Agreement as provided,  by law or
in equity. No exercise by Agent or the Lender Group of one right or remedy shall
be deemed an  election,  and no waiver by Agent or the Lender Group of any Event
of Default shall be deemed a continuing  waiver. No delay by Agent or the Lender
Group shall constitute a waiver, election or acquiescence by it.

     10. TAXES AND EXPENSES.

         If  Borrower  fails  to pay any  monies  (whether  taxes,  assessments,
remittances,  source  deductions,  insurance  premiums or, in the case of leased
properties or assets,  rents or other amounts  payable under such leases) due to
third  Persons,  or fails to make any deposits or furnish any required  proof of
payment or deposit,  all as required  under the terms of this  Agreement,  then,
Agent, in its sole  discretion and without prior notice to Borrower,  may do any
or all of the following:  (a) make payment of the same or any part thereof,  (b)
set up such  reserves in  Borrower's  Loan  Account as Agent deems  necessary to
protect the Lender Group from the exposure created by such failure or (c) in the
case of the failure to comply  with  Section  6.6  hereof,  obtain and  maintain
insurance policies of the type described in Section 6.6 and take any action with
respect to such policies as Agent deems prudent.  Any such amounts paid by Agent
shall  constitute  Lender  Group  Expenses  and  any  such  payments  shall  not
constitute  an agreement  by the Lender  Group to make  similar  payments in the
future or a waiver by the  Lender  Group of any  Unmatured  Default  or Event of
Default  under  this  Agreement.  Agent need not  inquire as to, or contest  the
validity of, any such expense, tax or Lien and the receipt of the usual official
notice for the payment  thereof shall be  conclusive  evidence that the same was
validly due and owing.

     11. WAIVERS; INDEMNIFICATION.

         11.1 Demand;  Protest; etc. Borrower waives demand,  protest, notice of
protest,  notice of  default or  dishonor,  notice of  payment  and  nonpayment,
nonpayment at maturity, release, compromise,  settlement,  extension, or renewal



of documents,  instruments,  chattel  paper,  and guarantees at any time held by
Agent or the Lender Group on which Borrower may in any way be liable.

         11.2 The Lender  Group's  Liability  for  Collateral.  Borrower  hereby
agrees  that the  Lender  Group  shall  not in any way or  manner  be  liable or
responsible for: (i) the safekeeping of the Collateral,  (ii) any loss or damage
thereto occurring or arising in any manner or fashion from any cause,  (iii) any
diminution  in the value  thereof  or (iv) any act or  default  of any  carrier,
warehouseman,  bailee,  forwarding  agency or other  Person  and (b) all risk of
loss, damage or destruction of the Collateral shall be borne by Borrower.

         11.3  Indemnification.  Borrower shall pay, indemnify,  defend and hold
Agent-Related  Persons, the Lender-Related  Persons with respect to each Lender,
each Participant (subject to Section  14.1(e)(v)),  and each of their respective
officers,   directors,   employees,  agents,  and  attorneys-in-fact  (each,  an
"Indemnified Person") harmless (to the fullest extent permitted by law) from and
against  any  and  all  claims,   demands,   suits,   actions,   investigations,
proceedings,  and damages,  and all reasonable  lawyers fees (on a solicitor and
their own client basis) and  disbursements and other costs and expenses actually
incurred in connection therewith (as and when they are incurred and irrespective
of whether suit is brought),  at any time  asserted  against,  imposed  upon, or
incurred by any of them (a) in  connection  with or as a result of or related to
the  execution,  delivery,  enforcement,   performance,   amendment,  waiver  or
administration  of  this  Agreement,  any  of the  other  Loan  Document  or the
transactions  contemplated  hereby  or  thereby  and  (b)  with  respect  to any
investigation,  litigation or proceeding  related to this  Agreement,  any other
Loan  Document  or the use of the  proceeds  of the  credit  provided  hereunder
(irrespective of whether any Indemnified Person is a party thereto), or any act,
omission,  event  or  circumstance  in  any  manner  related  thereto  (all  the
foregoing,  collectively,  the "Indemnified Liabilities").  The foregoing to the
contrary  notwithstanding,  Borrower shall have no obligation to any Indemnified
Person under this Section 11.3 with respect to any Indemnified  Liability that a
court of competent  jurisdiction  finally  determines  to have resulted from the
gross  negligence  or  willful  misconduct  of  such  Indemnified  Person.  This
provision  shall survive the  termination of this Agreement and the repayment of
the  Obligations.  If any  Indemnified  Person  makes any  payment  to any other
Indemnified Person with respect to an Indemnified Liability as to which Borrower
was required to indemnify the  Indemnified  Person  receiving such payment,  the
Indemnified  Person  making  such  payment is  entitled  to be  indemnified  and
reimbursed by Borrower with respect thereto.  WITHOUT LIMITATION,  THE FOREGOING
INDEMNITY  SHALL APPLY TO EACH  INDEMNIFIED  PERSON WITH RESPECT TO  INDEMNIFIED
LIABILITIES  WHICH IN WHOLE OR IN PART  CAUSED BY OR ARISE OUT OF ANY  NEGLIGENT
ACT OR OMISSION OF SUCH INDEMNIFIED PERSON OR OF ANY OTHER PERSON.

         11.4 Annual  Rates of  Interest.  For the  purposes of the Interest Act
(Canada),  whenever interest payable pursuant to this Agreement is calculated on
the basis of a period other than a calendar year (the "Interest  Period"),  each
rate of interest determined pursuant to such calculation  expressed as an annual
rate is equivalent to such rate as so determined multiplied by the actual number
of days in the calendar year in which the same is to be ascertained  and divided
by the number of days in the Interest Period.


12.      NOTICES.

         Unless otherwise  provided in this Agreement,  all notices,  demands or
service  of  documents  by  Borrower  or Agent  to the  other  relating  to this
Agreement,  any other Loan Document and any action or proceeding related thereto

     13. CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER.

         (a) THE VALIDITY OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS (UNLESS
EXPRESSLY  PROVIDED TO THE CONTRARY IN ANOTHER LOAN  DOCUMENT IN RESPECT OF SUCH
OTHER LOAN DOCUMENT), THE CONSTRUCTION,  INTERPRETATION,  AND ENFORCEMENT HEREOF
AND  THEREOF,  AND THE RIGHTS OF THE PARTIES  HERETO AND THERETO WITH RESPECT TO
ALL MATTERS  ARISING  HEREUNDER OR THEREUNDER OR RELATED HERETO OR THERETO SHALL
BE DETERMINED  UNDER,  GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF
THE PROVINCE OF ALBERTA WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICTS OF LAW.


         (b)  EACH OF THE  PARTIES  HEREBY  AGREES  THAT  ANY  LEGAL  ACTION  OR
PROCEEDING  AGAINST BORROWER WITH RESPECT TO THIS AGREEMENT,  OR ANY OF THE LOAN
DOCUMENTS  MAY BE  BROUGHT IN THE  COURTS OF THE  PROVINCE  OF ALBERTA OR IN THE
STATE AND FEDERAL  COURTS  LOCATED IN THE COUNTY OF NEW YORK,  STATE OF NEW YORK
AND EACH PARTY  SUBMITS AND ATTORNS TO, THE  NON-EXCLUSIVE  JURISDICTION  OF THE
AFORESAID COURTS.

         (c) EACH PARTY  WAIVES  ANY RIGHT TO STAY OR TO  DISMISS  ANY ACTION OR
PROCEEDING  BROUGHT  BEFORE  SAID  COURTS ON THE BASIS OF FORUM NON  CONVENIENS.
NOTHING  HEREIN SHALL  AFFECT THE RIGHT OF THE LENDER GROUP TO SERVE  PROCESS IN
ANY OTHER  MANNER  PERMITTED BY LAW OR SHALL LIMIT THE RIGHT OF THE LENDER GROUP
TO BRING PROCEEDINGS AGAINST BORROWER IN THE COURTS OF ANY JURISDICTION.

         (d) BORROWER AND THE LENDER GROUP HEREBY WAIVE THEIR RESPECTIVE  RIGHTS
TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY
OF THE LOAN DOCUMENTS OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING
CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR
STATUTORY CLAIMS. BORROWER AND THE LENDER GROUP REPRESENT THAT EACH HAS REVIEWED
THIS WAIVER AND EACH  KNOWINGLY  AND  VOLUNTARILY  WAIVES ITS JURY TRIAL  RIGHTS
FOLLOWING CONSULTATION WITH LEGAL COUNSEL. IN THE EVENT OF LITIGATION, A COPY OF
THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

         13.2 Waiver of Judgment Interest Act (Alberta). To the extent permitted
by applicable  Law, the  provisions of the Judgment  Interest Act (Alberta) will
not apply to the Loan Documents and are hereby expressly waived by Borrower.

         13.3  Deemed  Reinvestment  Not  Applicable.  For the  purposes  of the

     14. ASSIGNMENTS AND PARTICIPATIONS; SUCCESSORS.

         14.1 Assignments and Participations.

               (a) Any Lender may, with the written  consent of Agent  (provided
that no written  consent  of Agent  shall be  required  in  connection  with any
assignment  and  delegation by a Lender to an Eligible  Transferee),  assign and
delegate to one or more assignees (each an "Assignee")  all, or any part of all,
of the Obligations, the Commitments and the other rights and obligations of such
Lender hereunder and under the other Loan Documents, in a minimum amount of U.S.
$1,000,000  (except  such minimum  amount shall not apply to any  Affiliate of a



Lender or to a Related Fund or account managed by a Lender); provided,  however,
that  Borrower  and Agent may  continue  to deal solely and  directly  with such
Lender in  connection  with the  interest so  assigned to an Assignee  until (i)
written  notice  of  such  assignment,   together  with  payment   instructions,
addresses, and related information with respect to the Assignee, have been given
to Borrower and Agent by such Lender and the Assignee,  (ii) such Lender and its
Assignee have  delivered to Borrower and Agent a fully  executed  Assignment and
Acceptance,  and (iii) the  assignor  Lender or  Assignee  has paid to Agent for
Agent's separate account a processing fee in the amount of U.S. $5,000. Anything
contained herein to the contrary notwithstanding, the consent of Agent shall not
be  required  (and  payment  of any  fees  shall  not be  required)  if (x) such
assignment is in connection with any merger,  consolidation,  sale,  transfer or
other  disposition  of all or any  substantial  portion of the  business or loan
portfolio  of such Lender or (y) the  assignee is an  Affiliate of a Lender or a
Related Fund.

               (b) From and after  the date that  Agent  notifies  the  assignor
Lender  (with  a copy  to  Borrower)  that  it has  received  a  fully  executed
Assignment and Acceptance  and payment (if  applicable) of the  above-referenced
processing fee, (i) the Assignee  thereunder shall be a party hereto and, to the
extent that rights and  obligations  hereunder have been assigned to it pursuant
to such  Assignment and  Acceptance,  shall have the rights and obligations of a
Lender under the Loan  Documents,  and (ii) the assignor  Lender  shall,  to the
extent that rights and obligations  hereunder and under the other Loan Documents
have been assigned by it pursuant to such Assignment and Acceptance,  relinquish
its rights (except with respect to Section 11.3 hereof) and be released from its
obligations  under  this  Agreement  (and  in  the  case  of an  Assignment  and
Acceptance covering all or the remaining portion of an assigning Lender's rights
and obligations  under this Agreement and the other Loan Documents,  such Lender
shall cease to be a party hereto and thereto),  and such assignment shall affect
a novation between Borrower and the Assignee.

               (c) By executing and delivering an Assignment and Acceptance, the
assigning  Lender  thereunder and the Assignee  thereunder  confirm to and agree
with each  other and the other  parties  hereto as  follows:  (1) other  than as
provided in such  Assignment  and  Acceptance,  such  assigning  Lender makes no
representation  or warranty  and assumes no  responsibility  with respect to any
statements,  warranties or  representations  made in or in connection  with this
Agreement or the execution,  legality,  validity,  enforceability,  genuineness,
sufficiency  or value of this  Agreement  or any other Loan  Document  furnished
pursuant hereto,  (2) such assigning Lender makes no  representation or warranty
and  assumes no  responsibility  with  respect  to the  financial  condition  of
Borrower or the  performance or observance by Borrower of any of its obligations
under this Agreement or any other Loan Document  furnished  pursuant hereto, (3)
such Assignee  confirms that it has received a copy of this Agreement,  together
with such other documents and  information as it has deemed  appropriate to make
its own  credit  analysis  and  decision  to  enter  into  such  Assignment  and
Acceptance,  (4) such Assignee  will,  independently  and without  reliance upon
Agent,  such assigning  Lender or any other Lender,  and based on such documents
and information as it shall deem  appropriate at the time,  continue to make its
own credit  decisions in taking or not taking action under this  Agreement,  (5)
such Assignee appoints and authorizes Agent to take such actions and to exercise
such powers under this Agreement as are delegated to Agent, by the terms hereof,



together with such powers as are  reasonably  incidental  thereto,  and (6) such
Assignee agrees that it will perform all of the  obligations  which by the terms
of this Agreement are required to be performed by it as a Lender.

               (d) Immediately  upon each  Assignee's  making its processing fee
payment under the Assignment and Acceptance and receipt and  acknowledgement  by
Agent of such fully executed Assignment and Acceptance,  this Agreement shall be
deemed to be amended to the extent, but only to the extent, necessary to reflect
the addition of the Assignee and the  resulting  adjustment  of the  Commitments
arising therefrom.  The Commitment  allocated to each Assignee shall reduce such
Commitments of the assigning Lender pro tanto.

               (e) Any  Lender  may at any time,  with the  written  consent  of
Agent,  sell to one or more commercial  banks,  financial  institutions or other
Persons not Affiliates of such Lender (a "Participant")  participating interests
in its Obligations owing to such Lender,  the Commitment of such Lender, and the
other rights and interests of that Lender (the "Originating  Lender")  hereunder
and under the other Loan Documents  (provided  that no written  consent of Agent
shall  be  required  in  connection  with  any  sale of any  such  participating
interests by a Lender to an Eligible  Transferee);  provided,  however, that (i)
the  Originating  Lender  shall  remain  a  "Lender"  for all  purposes  of this
Agreement  and the  other  Loan  Documents  and the  Participant  receiving  the
participating interest in the Obligations, the Commitments, and the other rights
and  interests  of the  Originating  Lender  hereunder  shall not  constitute  a
"Lender"  hereunder  or under  the  other  Loan  Documents  and the  Originating
Lender's  obligations  under this  Agreement  shall remain  unchanged,  (ii) the
Originating  Lender shall remain solely  responsible for the performance of such
obligations,  (iii) Borrower,  Agent,  and Lenders shall continue to deal solely
and directly  with the  Originating  Lender in connection  with the  Originating
Lender's  rights  and  obligations  under  this  Agreement  and the  other  Loan
Documents,  (iv) no originating Lender shall transfer or grant any participating
interest under which the  Participant has the right to approve any amendment to,
or any consent or waiver  with  respect  to,  this  Agreement  or any other Loan
Document,  except to the extent  such  amendment  to, or consent or waiver  with
respect to this  Agreement  or of any other Loan  Document  would (A) extend the
final maturity date of the  Obligations  hereunder in which such  Participant is
participating,  (B) reduce  the  interest  rate  applicable  to the  Obligations
hereunder  in which  such  Participant  is  participating,  (C)  release  all or
substantially  all of the Collateral  (except to the extent  expressly  provided
herein or in any of the Loan Documents)  supporting the Obligations hereunder in
which such Participant is participating,  (D) postpone the payment of, or reduce
the amount of, the interest or fees payable to such Participant,  (E) change the
amount or due dates of scheduled principal repayments or prepayments or premiums
in  respect  of  the  Obligations   hereunder  in  which  such   Participant  is
participating  or (F)  subordinate  the Liens of Agent to the Liens of any other
creditor of Borrower,  and all amounts  payable by Borrower  hereunder  shall be
determined  as if such Lender had not sold such  participation,  except that, if
amounts  outstanding under this Agreement are due and unpaid, or shall have been
declared  or  shall  have  become  due and  payable  upon the  occurrence  of an
Unmatured Default or Event of Default,  each Participant shall be deemed to have
the right of set-off in respect of its  participating  interest in amounts owing
under this  Agreement  to the same extent as if the amount of its  participating
interest were owing directly to it as a Lender under this Agreement.  The rights
of any Participant only shall be derivative  through the Originating Lender with



whom such  Participant  participates  and no  Participant  shall have any rights
under this  Agreement or the other Loan Documents or any direct rights as to the
other Lenders,  Agent,  Borrower, the Collections or the Collateral or otherwise
in  respect  of  the  Obligations.  No  Participant  shall  have  the  right  to
participate directly in the making of decisions by Lenders among themselves. The
provisions  of this  Section  14.1(e)  are solely for the  benefit of the Lender
Group,  and Borrower  shall not have any rights as a third party  beneficiary of
such provisions.

               (f) In connection  with any such assignment or  participation  or
proposed assignment or participation, a Lender may disclose to a third party all
documents  and  information  which  it now or  hereafter  may have  relating  to
Borrower or Borrower's business.

               (g) Any other  provision in this Agreement  notwithstanding,  any
Lender residing in the United States may at any time create a security  interest
in, or  pledge,  all or any  portion of its rights  under and  interest  in this
Agreement in favor of any Federal  Reserve Bank in accordance  with Regulation A
of the Federal Reserve Bank or U.S. Treasury  Regulation 31 CFR ss. 203.14,  and
such Federal  Reserve  Bank may enforce such pledge or security  interest in any
manner permitted under applicable law.

               (h)  Borrower  shall  maintain,  or  cause  to be  maintained,  a
register  (the  "Register")  on which  it  enters  the  name of a Lender  as the
registered owner of each Advance held by such Lender. A Registered Loan (and the
Registered  Note, if any,  evidencing the same) may be assigned or sold in whole
or in part only by  registration of such assignment or sale on the Register (and
each Registered Note shall expressly so provide).  Any assignment or sale of all
or part of such Registered Loan (and the Registered Note, if any, evidencing the
same) may be effected  only by  registration  of such  assignment or sale on the
Register, together with the surrender of the Registered Note, if any, evidencing
the same duly endorsed by (or accompanied by a written  instrument of assignment
or sale duly executed by) the holder of such Registered Note, whereupon,  at the
request  of  the  designated  assignee(s)  or  transferee(s),  one or  more  new
Registered  Notes in the same aggregate  principal amount shall be issued to the
designated assignee(s) or transferee(s). Prior to the registration of assignment
or sale of any Registered  Loan (and the Registered  Note, if any evidencing the
same),  Borrower shall treat the Person in whose name such  Registered Loan (and
the  Registered  Note, if any,  evidencing  the same) is registered as the owner
thereof  for the purpose of  receiving  all  payments  thereon and for all other
purposes,  notwithstanding  notice to the contrary. In the case of an assignment
or delegation covered by Section 14.1(a)(y), the assigning Lender shall maintain
a comparable Register on behalf of Borrower.

               (i) In  the  event  that a  Lender  sells  participations  in the
Registered  Loan,  such Lender shall  maintain a register on which it enters the
name of all  participants in the Registered  Loans held by it (the  "Participant
Register").  A Registered Loan (and the Registered Note, if any,  evidencing the
same)  may be  participated  in whole or in part  only by  registration  of such
participation  on the  Participant  Register  (and each  Registered  Note  shall
expressly  so  provide).  Any  participation  of such  Registered  Loan (and the
Registered  Note,  if any,  evidencing  the  same) may be  effected  only by the
registration of such participation on the Participant Register.


         14.2 Successors.  This Agreement shall bind and inure to the benefit of
the respective  successors and assigns of each of the parties hereto;  provided,
however,  that  Borrower  may not assign this  Agreement or any rights or duties
hereunder  without Lenders' prior written consent and any prohibited  assignment
shall be  absolutely  void ab initio.  No consent to assignment by Lenders shall
release  Borrower from its  Obligations.  A Lender may assign this Agreement and
the other Loan  Documents  and its rights and duties  hereunder  and  thereunder
pursuant to Section 14.1 hereof and,  except as expressly  required  pursuant to
Section  14.1  hereof,  no  consent or  approval  by  Borrower  is  required  in
connection with any such assignment.

     15. AMENDMENTS; WAIVERS.

         15.1 Amendments and Waivers. No amendment or waiver of any provision of
this  Agreement or any other Loan  Document,  and no consent with respect to any
departure by Borrower therefrom,  shall be effective unless the same shall be in
writing and signed by the Required  Lenders (or by Agent at the written  request
of the Required  Lenders) and Borrower and then any such waiver or consent shall
be  effective  only in the specific  instance  and for the specific  purpose for
which given; provided, however, that no such waiver, amendment or consent shall,
unless in writing  and signed (or  otherwise  authorized)  by all of the Lenders
affected thereby and Borrower, do any of the following:

               (a) increase or extend any Commitment of any Lender,

               (b)  postpone  or delay any date fixed by this  Agreement  or any
other Loan  Document  for any  payment  of  principal,  interest,  fees or other
amounts due hereunder or under any other Loan Document,

               (c) reduce the principal of, or the rate of interest on, any loan
or other  extension  of credit  hereunder,  or reduce any fees or other  amounts
payable hereunder or under any other Loan Document,

               (d) change the percentage of the Commitments  that is required to
take any action hereunder,

               (e) amend,  modify or waive this  Section 15 or any  provision of
the Agreement providing for consent or other action by all Lenders,

               (f) [Intentionally omitted],

               (g) change the  definition  of  "Required  Lenders"  or "Pro Rata
Share",

               (h) [Intentionally omitted],

               (i)  release  Borrower  from any  obligation  for the  payment of
money,

               (j) change,  modify or waive the definition of "PV-10",  "Related
Indebtedness" or "Proved Developed Reserves Amount", or


               (k)  amend,  modify or waive any of the  provisions  of  Sections
2.3(b),  3.4 or 16 (or change any definition of a term used in such Section in a
manner adverse to any such Lender),

and,  provided  further,  however,  that no amendment,  waiver or consent shall,
unless in writing and signed by Agent,  affect the rights or duties of Agent, as
applicable,  under this  Agreement  or any other Loan  Document.  The  foregoing
notwithstanding,  any amendment,  modification,  waiver, consent, termination or
release of, or with  respect to, any  provision  of this  Agreement or any other
Loan  Document that relates only to the  relationship  of the Lender Group among
themselves,  and that does not  affect the rights or  obligations  of  Borrower,
shall not,  subject to Section  14.1(a),  require consent by or the agreement of
Borrower.

         15.2 Replacement of Holdout Lender.

               (a)  If  any  action  to be  taken  by the  Lender  Group,  Agent
hereunder  or under any other Loan  Document  requires  the  unanimous  consent,
authorization or agreement of all Lenders, and a Lender ("Holdout Lender") fails
to give its consent,  authorization  or agreement,  then Agent,  upon at least 5
Business Days' prior irrevocable  notice to the Holdout Lender,  may permanently
replace  the  Holdout  Lender  with  one or more  substitute  Lenders  (each,  a
"Replacement  Lender"),  and the Holdout Lender shall have no right to refuse to
be replaced  hereunder.  Such notice to replace the Holdout Lender shall specify
an effective  date for such  replacement,  which date shall not be later than 15
Business Days after the date such notice is given.

               (b) Prior to the effective date of such replacement,  the Holdout
Lender and each  Replacement  Lender shall execute and deliver an Assignment and
Acceptance Agreement,  subject only to the Holdout Lender being repaid its share
of the  outstanding  Obligations  without  any  premium  or  penalty of any kind
whatsoever.  If the Holdout  Lender  shall refuse or fail to execute and deliver
any such Assignment and Acceptance Agreement prior to the effective date of such
replacement,  the Holdout  Lender shall be deemed to have executed and delivered
such Assignment and Acceptance Agreement.  The replacement of any Holdout Lender
shall be made in accordance  with the terms of Section 14.1.  Until such time as
the  Replacement  Lenders  shall  have  acquired  all  of the  Obligations,  the
Commitments and the other rights and obligations of the Holdout Lender hereunder
and under the other Loan Documents, the Holdout Lender shall remain obligated to
make the Holdout Lender's Pro Rata Share of Advances (if any).

         15.3 No Waivers; Cumulative Remedies. No failure by Agent or any Lender
to exercise any right,  remedy or option under this  Agreement or any other Loan
Document,  or delay by Agent or any Lender in exercising the same,  will operate
as a waiver thereof.  No waiver by Agent or any Lender will be effective  unless
it is in writing,  and then only to the extent specifically stated. No waiver by
Agent or any Lender on any occasion  shall  affect or diminish  Agent's and each
Lender's  rights  thereafter to require  strict  performance  by Borrower of any
provision  of this  Agreement  or any  other  Loan  Document.  Agent's  and each
Lender's  rights  under  this  Agreement  and the other Loan  Documents  will be
cumulative  and not  exclusive  of any other  right or remedy  that Agent or any
Lender may have.


     16. AGENT; LENDER GROUP.

         16.1  Appointment  and  Authorization  of  Agent.  Each  Lender  hereby
designates and appoints GCF as its  representative  under this Agreement and the
other Loan Documents and each Lender hereby irrevocably authorizes Agent to take
such action on its behalf under the  provisions of this Agreement and each other
Loan  Document  and to  exercise  such  powers and  perform  such  duties as are
expressly  delegated  to Agent by the terms of this  Agreement or any other Loan
Document,  together with such powers as are reasonably incidental thereto. Agent
agrees to act as such on the express  conditions  contained  in this Section 16.
Except as otherwise  specifically  provided in Section 16.17,  the provisions of
this  Section 16 are solely for the benefit of Agent and  Lenders,  and Borrower
shall  have no  rights as a third  party  beneficiary  of any of the  provisions
contained  herein.  Any  provision to the contrary  contained  elsewhere in this
Agreement or in any other Loan  Document  notwithstanding,  Agent shall not have
any duties or  responsibilities,  except those  expressly set forth herein,  nor
shall  Agent  have or be  deemed  to have any  fiduciary  relationship  with any
Lender,  and  no  implied  covenants,   functions,   responsibilities,   duties,
obligations or  liabilities  shall be read into this Agreement or any other Loan
Document or otherwise  exist against Agent;  it being  expressly  understood and
agreed that the use of the word  "Agent" is for  convenience  only,  that GCF is
merely the  representative of Lenders,  and only has the contractual  duties set
forth herein.  Except as expressly  otherwise provided in this Agreement,  Agent
shall  have  and may use its sole  discretion  with  respect  to  exercising  or
refraining from exercising any discretionary rights or taking or refraining from
taking any actions  that Agent  expressly is entitled to take or assert under or
pursuant to this Agreement and the other Loan  Documents.  Without  limiting the
generality of the  foregoing,  or of any other  provision of the Loan  Documents
that provides rights or powers to Agent, Lenders agree that Agent shall have the
right to exercise  the  following  powers as long as this  Agreement  remains in
effect:  (a) maintain,  in accordance  with its  customary  business  practices,
ledgers and records  reflecting the status of the  Obligations,  the Collateral,
the Collections and related  matters,  (b) execute or file any and all financing
or similar statements or notices, amendments, renewals, supplements,  documents,
instruments,  proofs of claim, notices and other written agreements with respect
to the Loan Documents,  (c) make Advances, for itself or on behalf of Lenders as
provided in the Loan Documents,  (d) exclusively  receive,  apply and distribute
the  Collections as provided in the Loan  Documents,  (e) open and maintain such
bank  accounts and cash  management  arrangements  as Agent deems  necessary and
appropriate  in accordance  with the Loan  Documents for the foregoing  purposes
with respect to the Collateral and the  Collections,  (f) perform,  exercise and
enforce any and all other  rights and  remedies of the Lender Group with respect
to Borrower,  the  Obligations,  the Collateral or the  Collections or otherwise
related to any of same as provided in the Loan Documents,  and (g) incur and pay
such Lender Group Expenses as Agent may deem  necessary or  appropriate  for the
performance  and  fulfillment  of its functions and powers  pursuant to the Loan
Documents.

         16.2  Delegation  of Duties.  Agent may execute any of its duties under
this  Agreement or any other Loan  Document by or through  agents,  employees or
attorneys-in-fact  and shall be  entitled  to advice of counsel  concerning  all
matters  pertaining  to such  duties.  Agent  shall not be  responsible  for the
negligence  or misconduct  of any agent or  attorney-in-fact  that it selects as
long as such selection was made without gross negligence or willful misconduct.


         16.3  Liability of Agent  Persons.  None of the  Agent-Related  Persons
shall (i) be liable for any  action  taken or omitted to be taken by any of them
under or in  connection  with this  Agreement or any other Loan  Document or the
transactions contemplated hereby or thereby (except for its own gross negligence
or  willful  misconduct)  or (ii) be  responsible  in any  manner  to any of the
Lenders for any recital, statement,  representation or warranty made by Borrower
or any Subsidiary or Affiliate of Borrower,  or any officer or director thereof,
contained  in  this  Agreement  or  in  any  other  Loan  Document,  or  in  any
certificate, report, statement or other document referred to or provided for in,
or received by Agent under or in connection  with,  this  Agreement or any other
Loan Document, or the validity,  effectiveness,  genuineness,  enforceability or
sufficiency of this Agreement or any other Loan Document,  or for any failure of
Borrower  or any other party to any Loan  Document  to perform  its  obligations
hereunder or thereunder.  No Agent-Related  Person shall be under any obligation
to any Lender to ascertain or to inquire as to the  observance or performance of
any of the  agreements  contained  in, or conditions  of, this  Agreement or any
other Loan  Document,  or to inspect the Books or  properties of Borrower or the
books or records or properties of any of Borrower's Subsidiaries or Affiliates.

         16.4 Reliance by Agent.  Agent shall be entitled to rely,  and shall be
fully  protected in relying,  upon any  writing,  resolution,  notice,  consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement  or other  document or  conversation  believed by it to be genuine and
correct and to have been signed,  sent or made by the proper  Person or Persons,
and upon advice and statements of legal counsel  (including  counsel to Borrower
or counsel to any Lender), independent accountants and other experts selected by
Agent.  Agent shall be fully justified in failing or refusing to take any action
under this Agreement or any other Loan Document unless Agent shall first receive
such advice or concurrence of the Lenders as it deems appropriate and until such
instructions are received,  Agent shall act, or refrain from acting, as it deems
advisable. If Agent so requests, it shall first be indemnified to its reasonable
satisfaction  by Lenders  against any and all  liability and expense that may be
incurred by it by reason of taking or continuing to take any such action.  Agent
shall in all cases be fully  protected in acting,  or in refraining from acting,
under this Agreement or any other Loan Document in accordance  with a request or
consent of  Lenders,  and such  request  and any action  taken or failure to act
pursuant thereto shall be binding upon all of Lenders.

         16.5 Notice of Default or Event of  Default.  Agent shall not be deemed
to have knowledge or notice of the occurrence of any Default,  Unmatured Default
or Event  of  Default,  except  with  respect  to  defaults  in the  payment  of
principal,  interest,  fees and  expenses  required  to be paid to Agent for the
account of the Lenders and with  respect to  Defaults,  Unmatured  Defaults  and
Events of Default of which Agent has actual  knowledge,  unless Agent shall have
received  written notice from a Lender or Borrower  referring to this Agreement,
describing such Default, Unmatured Default or Event of Default, and stating that
such notice is a "notice of default".  Agent promptly will notify the Lenders of
its receipt of any such notice or of any  Unmatured  Default or Event of Default
of which Agent has actual  knowledge.  If any Lender obtains actual knowledge of
any Unmatured Default or Event of Default, such Lender promptly shall notify the
other  Lenders and Agent of such  Unmatured  Default or Event of  Default.  Each
Lender shall be solely  responsible for giving any notices to its  Participants,
if any.  Subject to Section  16.4,  Agent shall take such action with respect to



such  Unmatured  Default or Event of Default as may be requested by the Required
Lenders in accordance with Section 9; provided,  however,  that unless and until
Agent has received any such  request,  Agent may (but shall not be obligated to)
take such  action,  or refrain  from taking such  action,  with  respect to such
Default, Unmatured Default or Event of Default as it shall deem advisable.

         16.6  Credit  Decision.  Each  Lender  acknowledges  that  none  of the
Agent-Related Persons has made any representation or warranty to it, and that no
act by Agent hereinafter taken,  including any review of the affairs of Borrower
and  its  Subsidiaries  or  Affiliates,   shall  be  deemed  to  constitute  any
representation  or warranty  by any  Agent-Related  Person to any  Lender.  Each
Lender represents to Agent that it has,  independently and without reliance upon
any  Agent-Related  Person and based on such documents and information as it has
deemed  appropriate,  made  its own  appraisal  of and  investigation  into  the
business,  prospects,  operations,  property,  financial and other condition and
creditworthiness  of Borrower and any other Person (other than the Lender Group)
party to a Loan Document,  and all applicable  bank  regulatory laws relating to
the transactions  contemplated  hereby,  and made its own decision to enter into
this  Agreement  and to extend credit to Borrower.  Each Lender also  represents
that it will,  independently and without reliance upon any Agent-Related  Person
and based on such documents and information as it shall deem  appropriate at the
time,  continue to make its own credit  analysis,  appraisals  and  decisions in
taking or not taking action under this  Agreement and the other Loan  Documents,
and to make such investigations as it deems necessary to inform itself as to the
business,  prospects,  operations,  property,  financial and other condition and
creditworthiness  of Borrower and any other Person (other than the Lender Group)
party to a Loan  Document.  Except for  notices,  reports,  and other  documents
expressly  herein required to be furnished to the Lenders by Agent,  Agent shall
not have any duty or  responsibility  to provide  any Lender  with any credit or
other  information  concerning the business,  prospects,  operations,  property,
financial  and other  condition  or  creditworthiness  of Borrower and any other
Person party to a Loan Document that may come into the  possession of any of the
Agent-Related Persons.

         16.7  Costs  and  Expenses;  Indemnification.  Agent  may incur and pay
Lender  Group  Expenses  to the  extent  Agent  reasonably  deems  necessary  or
appropriate for the  performance  and  fulfillment of its functions,  powers and
obligations  pursuant to the Loan Documents,  including court costs,  reasonable
lawyers' fees and expenses,  costs of collection by outside collection  agencies
and auctioneer fees and costs of security  guards or insurance  premiums paid to
maintain the Collateral, whether or not Borrower is obligated to reimburse Agent
or Lenders for such expenses pursuant to the Loan Agreement or otherwise.  Agent
is authorized and directed to deduct and retain sufficient amounts from received
by Agent to reimburse Agent for such  out-of-pocket  costs and expenses prior to
the distribution of any amounts to Lenders. In the event Agent is not reimbursed
for such costs and  expenses  from  Collections  received by Agent,  each Lender
hereby agrees that it is and shall be obligated to pay to or reimburse Agent for
the  amount  of  such  Lender's  Pro  Rata  Share  thereof.  Whether  or not the
transactions  contemplated  hereby are consummated,  the Lenders shall indemnify
upon demand the  Agent-Related  Persons (to the extent not  reimbursed  by or on
behalf of Borrower and without  limiting the  obligation  of Borrower to do so),
according  to their Pro Rata  Shares,  from and against any and all  Indemnified
Liabilities;  provided,  however, that no Lender shall be liable for the payment



to any  Agent-Related  Person of any  portion  of such  Indemnified  Liabilities
resulting  solely from such  Agent-Related  Person's gross negligence or willful
misconduct nor shall any Lender be liable for the  obligations of any Defaulting
Lender in failing to make an Advance or other extension of credit  hereunder (if
any).  Without  limitation of the foregoing,  each Lender shall  reimburse Agent
upon  demand  for such  Lender's  ratable  share of any  costs or  out-of-pocket
expenses  (including  lawyers  fees' and  expenses on a solicitor  and their own
client basis) incurred by Agent in connection with the  preparation,  execution,
delivery,  administration,   modification,  amendment  or  enforcement  (whether
through  negotiations or legal  proceedings or otherwise) of, or legal advice in
respect of rights or  responsibilities  under,  this  Agreement,  any other Loan
Document or any document  contemplated  by or referred to herein,  to the extent
that Agent is not reimbursed for such expenses by or on behalf of Borrower.  The
undertakings  in this  Section  shall  survive  the  payment of all  Obligations
hereunder and the resignation or replacement of Agent.

         16.8  Agent-Related  Persons  in  Individual  Capacity.   Agent-Related
Persons may make loans to,  issue  letters of credit for the account of,  accept
deposits from,  acquire equity interests in, and generally engage in any kind of
banking, lending, trust, financial advisory, underwriting or other business with
Borrower and its  Subsidiaries  and  Affiliates and any other Person (other than
the  Lender  Group)  party to any Loan  Document  as though  GCF was not a party
hereto,  and, in each case, without notice to or consent of the other members of
the  Lender  Group.  The other  members of the Lender  Group  acknowledge  that,
pursuant to such  activities,  Agent-Related  Persons  may  receive  information
regarding Borrower or its Affiliates and any other Person (other than the Lender
Group) party to any Loan Document that is subject to confidentiality obligations
in favor of Borrower or such other Person and that  prohibit the  disclosure  of
such  information  to the Lenders,  and the Lenders  acknowledge  that,  in such
circumstances  (and  in  the  absence  of  a  waiver  of  such   confidentiality
obligations, which waiver Agent will use its reasonable best efforts to obtain),
Agent shall not be under any obligation to provide such information to them. The
terms "Lender" and "Lenders" include GCF in its individual capacity.

         16.9 Successor Agent.

               (a)  Agent  may  resign  as  Agent  upon 45 days'  notice  to the
Lenders.  If Agent resigns under this Agreement,  the Required Lenders and Agent
shall  appoint a  successor  Agent for the  Lenders.  If no  successor  Agent is
appointed  prior to the effective date of the  resignation  of Agent,  Agent may
appoint a successor Agent. If Agent has materially breached or failed to perform
any material  provision of this  Agreement  or of  applicable  law, the Required
Lenders may agree in writing to remove and replace Agent with a successor  Agent
from among the Lenders.

               (b) Nothing  contained in this Section 16.9 shall be construed to
limit or eliminate  Agent's right to resign as an Agent in accordance  with this
Section  16.9. In any such event,  upon the  acceptance  of its  appointment  as
successor Agent hereunder, such successor Agent shall succeed to all the rights,
powers and duties of the  retiring  Agent and the term  "Agent"  shall mean such
successor Agent and the retiring Agent's appointment, powers and duties as Agent
shall be terminated.  After any retiring Agent's resignation hereunder as Agent,



the  provisions  of this Section 16 shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Agent under this  Agreement.  If
no  successor  Agent has accepted  appointment  as Agent by the date which is 45
days following a retiring  Agent's notice of resignation,  the retiring  Agent's
resignation shall nevertheless  thereupon become effective and the Lenders shall
perform  all of the duties of Agent  hereunder  until such time,  if any, as the
Lenders appoint a successor  Agent as provided for above.  Each of the resigning
Agent and Borrower agrees to cooperate with the successor Agent in effecting the
appointment  of such  successor  Agent,  including  executing such documents and
instruments  of transfer,  and taking such other  actions,  in each case without
recourse,  representation  or warranty to the  resigning  Agent,  as  reasonably
requested by such successor Agent.

         16.10  Lender in  Individual  Capacity.  Any Lender and its  respective
Affiliates may make loans to, issue letters of credit for the account of, accept
deposits from,  acquire equity  interests in and generally engage in any kind of
banking, trust, financial advisory, underwriting or other business with Borrower
and its  Subsidiaries and Affiliates and any other Person (other than the Lender
Group)  party to any Loan  Document  as  though  such  Lender  were not a Lender
hereunder without notice to or consent of the other members of the Lender Group.
The other  members  of the  Lender  Group  acknowledge  that,  pursuant  to such
activities,  such Lender and its respective  Affiliates may receive  information
regarding Borrower or its Affiliates and any other Person (other than the Lender
Group) party to any Loan Document that is subject to confidentiality obligations
in favor of Borrower or such other Person and that  prohibit the  disclosure  of
such  information  to the Lenders,  and the Lenders  acknowledge  that,  in such
circumstances  (and  in  the  absence  of  a  waiver  of  such   confidentiality
obligations,  which waiver such Lender will use its  reasonable  best efforts to
obtain),  such  Lender  not  shall be  under  any  obligation  to  provide  such
information to them.

         16.11 Withholding Taxes.

               (a) Until the Agent is delivered an opinion,  acceptable to it in
its sole discretion, of a nationally recognized Canadian law firm that no amount
is required  to be withheld or deducted  pursuant to Part XIII of the Income Tax
Act  (Canada)  with respect to payment of the  Obligations;  for the purposes of
Subsection  16.11(b),  the Borrower  acknowledges and agrees that subject to the
application of the Canada - United States Tax Convention  (1980), it is required
to withhold and remit pursuant to Part XIII of the Income Tax Act (Canada),  25%
of the amount of each  payment of the  Obligations  (other than a  repayment  of
principal) made to a Non-Resident  Lender;  and further the Borrower agrees that
it shall  withhold and remit such amounts in  accordance  with the  provision of
Subsection 16.11(b) and Part XIII of the Income Tax Act (Canada).

               (b) All payments of the  Obligations  made hereunder or under the
other Loan Documents by or on behalf of the Borrower to Non-Resident  Lenders or
to Agent on their behalf will be made free and clear of and without  withholding
or  deduction  for or on account of any  Withholding  Tax unless the Borrower is
required to withhold or deduct Taxes by Applicable Law or by the  interpretation
or administration  thereof.  If the Borrower or Agent is so required to withhold
or deduct any amount for or on account of Withholding  Taxes from any payment of
the  Obligations,  the Borrower will pay as additional  interest such additional
amounts  ("Additional  Amounts")  as may be  necessary  so that  the net  amount



received  by  each  affected  Non-Resident  Lender  after  such  withholding  or
deduction  (including with respect to Additional  Amounts) will not be less than
the amount such Lender  would have  received if such  Withholding  Taxes had not
been withheld or deducted; provided, however, that no Additional Amounts will be
payable with respect to a payment made to a  Non-Resident  Lender (an  "Excluded
Lender") (i) with which the Borrower does not deal at arm's length (for purposes
of the Income Tax Act (Canada)) at the time of the making of such payment,  (ii)
which is subject to such  Withholding  Taxes by reason of its  failure to comply
with any  certification,  identification,  information,  documentation  or other
reporting  requirement if compliance is required by Applicable Law,  regulation,
administrative  practice or an applicable  treaty as a precondition to exemption
from,  or a  reduction  in  the  rate  of  deduction  or  withholding  of,  such
Withholding Taxes, or (iii) which is subject to such Withholding Taxes by reason
of its carrying on business in or being connected with Canada or any province or
territory thereof otherwise than by the mere holding of its interest in the Loan
to which  payments  relate or the receipt of payments  thereunder.  The Borrower
will make such  withholding  or deduction and remit the full amount  deducted or
withheld to the relevant Authorized Authority as and when required in accordance
with  Applicable  Law.  The  Borrower  will pay all  Taxes,  interest  and other
liabilities  which arise by virtue of any failure of the  Borrower to  withhold,
deduct and remit to the relevant Authorized Authority on a timely basis the full
amount  required in accordance with Applicable Law. The Borrower will furnish to
the relevant  Non-Resident  Lender and Agent,  within 30 days after the date the
payment of any Withholding  Taxes is due pursuant to Applicable  Law,  certified
copies of tax receipts evidencing such payment by the Borrower.

               (c) If any Non-Resident  Lender is required to pay Tax under Part
XIII of the Income Tax Act (Canada) or any  successor  provisions  in respect of
any payment of the Obligations by or on behalf of the Borrower in  circumstances
where the  Borrower is not required to make a  withholding  with respect to such
Tax (for  instance,  in accordance  with Section 803 of the  Regulations  to the
Income Tax Act  (Canada)),  then the  Borrower  shall,  upon  demand by any such
Non-Resident  Lender indemnify such Non-Resident Lender (other than a Lender (i)
with which the  Borrower  does not deal at arm's  length  (for  purposes  of the
Income Tax Act (Canada)) at the time of the making of such  payment,  (ii) which
is  subject  to  such  Taxes  by  reason  of its  failure  to  comply  with  any
certification,  identification,  information,  documentation  or other reporting
requirement   if  compliance  is  required  by   Applicable   Law,   regulation,
administrative  practice or an applicable  treaty as a precondition to exemption
from, or a reduction in the rate of deduction of withholding  of, such Taxes, or
(iii) which is subject to such  Withholding  Taxes by reason of its  carrying on
business in or being connected with Canada or any province or territory  thereof
otherwise  than by the mere  holding of its  interest in the Credit  Facility to
which payments  relate or the receipt of payments  thereunder for the payment of
any such Taxes, together with any interest, penalties and expenses in connection
therewith. All such amounts shall be payable by the Borrower on demand and shall
bear interest at the rate borne by the Credit Facility  calculated from the date
incurred by the applicable Non-Resident Lender to the date paid by the Borrower.

               (d) If the Borrower pays any amount pursuant to Section  16.11(b)
with respect to any payment to a Non-Resident  Lender or, with the prior written
consent of such Lender,  provides any security  therefor  pursuant to Applicable



Law, and the Borrower at its expense  wishes to contest the  exigibility  of the
relevant  Taxes and  furnishes  to such  Non-Resident  Lender an  opinion of tax
counsel  satisfactory to such Non-Resident  Lender,  acting  reasonably,  to the
effect that there  exists a  reasonable  basis for  contesting  such Taxes,  the
Borrower may contest such Taxes, provided that:

               (i) the Borrower has otherwise complied with this Section 16.11;

               (ii) the Borrower has delivered to such Non-Resident  Lender such
additional  security or  assurances  as such  Non-Resident  Lender may  require,
acting reasonably,  in order to be satisfied that such Non-Resident  Lender will
not incur any  liability by reason of any  contestation,  including  legal fees,
disbursements, interest and penalties; and

               (iii)  the   institution,   conduct  and   continuation  of  such
proceedings  (including the settlement or compromise of same) will remain within
the sole discretion of such Non-Resident  Lender and will forthwith be abandoned
if such Non-Resident Lender so requires, acting reasonably, having regard to its
overall tax and related interests.

                    (e) If, following any payment made by the Borrower  pursuant
to Section  16.11(b)  hereof to a  Non-Resident  Lender,  any such  Non-Resident
Lender shall  receive or be granted a material  credit  against or remission for
any  other tax  payable  by it by  reason  of the  payment  of the tax which the
Borrower has  indemnified  the  Non-Resident  Lender for (and such  Non-Resident
Lender  is  able  to  readily   identify  such  credit  or  remission  as  being
attributable  to its loan  hereunder),  such  Non-Resident  Lender shall, to the
extent that it can do so without  prejudice  to the  retention  of the amount of
such credit or remission and without prejudice to the right of such Non-Resident
Lender to obtain any other  relief or  allowance  which may be  available to it,
reimburse  the Borrower  with such amount as such  Non-Resident  Lender,  acting
reasonably,  determines to be the amount of money attributable to such credit or
remission that may be paid by such  Non-Resident  Lender to leave it (after such
reimbursement) in no worse position than it would have been in had there been no
such  deduction or  withholding  or payment of tax which resulted in the payment
under  Section  16.11(b)  above.  Such  Non-Resident  Lender  may  charge to the
Borrower (and may deduct from amounts  reimbursable to the Borrower hereunder) a
fee reasonably  determined by such Non-Resident  Lender to compensate it for any
additional  effort  expended  or cost  incurred  in  determining  such credit or
remission or allocating it to the Borrower.  Notwithstanding  the foregoing,  no
Non-Resident  Lender shall be obligated to disclose to the  Borrower,  or any of
its agents, any computation made by such Non-Resident  Lender in connection with
this Section 16.11(e) or any information  regarding such  Non-Resident  Lender's
tax status or affairs.

         16.12 Collateral Matters

               (a) Lenders hereby irrevocably authorize Agent, at its option and
in its sole  discretion,  to  release  any Lien on any  Collateral  (i) upon the
termination of the Commitments and payment and  satisfaction in full by Borrower
of all Obligations,  (ii)  constituting  property being sold or disposed of if a
release is  required  or  desirable  in  connection  therewith  and if  Borrower
certifies to Agent that the sale or disposition is not prohibited  under Section



7.4 (and Agent may rely  conclusively on any such  certificate,  without further
inquiry), (iii) constituting property in which Borrower owned no interest at the
time  the  security  interest  was  granted  or at any time  thereafter  or (iv)
constituting  property  leased to Borrower  under a lease that has expired or is
terminated in a transaction permitted under this Agreement.  Notwithstanding the
foregoing,  so long no Unmatured Default or Event of Default shall have occurred
and be continuing,  Agent shall, for the benefit and at the request of Borrower,
release  its  Lien on  Collateral  in a  transaction  constituting  a  Permitted
Disposition.  Except as  provided  above,  Agent will not  execute and deliver a
release of any Lien on any Collateral without the prior written authorization of
(y) if the release is of all or substantially all of the Collateral,  all of the
Lenders  or (z)  otherwise,  the  Required  Lenders.  Upon  request  by Agent or
Borrower at any time, the Lenders will confirm in writing Agent's authority,  as
the case may be,  to  release  any such  Liens on  particular  types or items of
Collateral pursuant to this Section 16.12; provided, however, that (1) the Agent
shall not be required to execute any document necessary to evidence such release
on terms that,  in Agent's  opinion,  as the case may be,  would expose Agent to
liability  or create any  obligation  or entail any  consequence  other than the
release of such Lien without  recourse,  representation or warranty and (2) such
release shall not in any manner  discharge,  affect or impair the Obligations or
any Liens (other than those  expressly  being  released) upon (or obligations of
Borrower  in respect of) all  interests  retained by  Borrower,  including,  the
proceeds of any sale,  all of which shall  continue  to  constitute  part of the
Collateral.

               (b) Agent  shall  not have any  obligation  whatsoever  to any of
Lenders to assure that the Collateral exists or is owned by Borrower or is cared
for,  protected or insured or has been  encumbered,  or that Agent's  Liens have
been  properly or  sufficiently  or lawfully  created,  perfected,  protected or
enforced or are entitled to any particular priority, or to exercise at all or in
any particular manner or under any duty of care,  disclosure or fidelity,  or to
continue  exercising,  any of the  rights,  authorities  and  powers  granted or
available to Agent pursuant to any of the Loan  Documents,  it being  understood
and agreed  that in respect of the  Collateral,  or any act,  omission  or event
related thereto, subject to the terms and conditions contained herein, Agent may
act in any manner it may deem appropriate,  absent Agent's,  as the case may be,
gross  negligence  or willful  misconduct  as finally  determined  by a court of
competent jurisdiction, in its sole discretion given Agent's own interest in the
Collateral  in its capacity as one of Lenders and that Agent shall have no other
duty or liability whatsoever to any Lender as to any of the foregoing, except as
otherwise provided herein.

         16.13 Restrictions on Actions by Lenders; Sharing of Payments.


               (a) Each of the  Lenders  agrees  that it shall not,  without the
express  consent  of Agent,  and that it  shall,  to the  extent it is  lawfully
entitled to do so, upon the request of Agent,  set off against the  Obligations,
any amounts owing by such Lender to Borrower or any deposit accounts of Borrower
now or hereafter maintained with such Lender. Each of the Lenders further agrees
that it shall not,  unless  specifically  requested  to do so by Agent,  take or
cause to be taken  any  action,  including,  the  commencement  of any  legal or
equitable  proceedings,  to  foreclose  any Lien on, or  otherwise  enforce  any
security  interest in, any of the  Collateral  the purpose of which is, or could
be, to give such Lender any  preference  or priority  against the other  Lenders
with respect to the Collateral.


               (b) If,  at any time or times any  Lender  shall  receive  (i) by
payment,  foreclosure  or setoff or otherwise  any proceeds of Collateral or any
payments with respect to the  Obligations  arising  under,  or relating to, this
Agreement or the other Loan Documents,  except for any such proceeds or payments
received by such Lender from Agent pursuant to the terms of this  Agreement,  or
(ii)  payments  from Agent in excess of such  Lender's Pro Rata Share portion of
all such  distributions  by Agent,  such Lender promptly shall (1) turn the same
over to  Agent,  in kind,  and with  such  endorsements  as may be  required  to
negotiate the same to Agent, or in immediately  available  funds, as applicable,
for the account of all of the Lenders and for  application to the Obligations in
accordance with the applicable  provisions of this  Agreement,  or (2) purchase,
without  recourse or warranty,  an undivided  interest and  participation in the
Obligations owed to the other Lenders so that such excess payment received shall
be  applied  ratably  as among the  Lenders  in  accordance  with their Pro Rata
Shares;  provided,  however, that if all or part of such excess payment received
by the  purchasing  party is thereafter  recovered  from it, those  purchases of
participations  shall be rescinded in whole or in part, as  applicable,  and the
applicable portion of the purchase price paid therefor shall be returned to such
purchasing party, but without interest except to the extent that such purchasing
party is required to pay interest in connection  with the recovery of the excess
payment.

         16.14 Agency for Perfection. Agent hereby appoints each other Lender as
its agent (and each Lender hereby accepts such  appointment)  for the purpose of
perfecting the Liens of Agent in assets which,  in accordance with Section 35 of
the  PPSA  can be  perfected  only  by  possession.  Should  any  Lender  obtain
possession of any such Collateral,  such Lender shall notify Agent thereof, and,
promptly upon the request of Agent  therefor  shall  deliver such  Collateral to
Agent.

         16.15 Payments to Lenders.  All payments to be made by Agent to Lenders
shall  be made  by bank  wire  transfer  or  internal  transfer  of  immediately
available  funds pursuant to such wire transfer  instructions  as each party may
designate  for itself by written  notice to Agent.  Concurrently  with each such
payment,  Agent shall  identify  whether such  payment (or any portion  thereof)
represents principal, premium, or interest of the Obligations.

         16.16 Concerning the Collateral and Related Loan Documents. Each member
of the Lender Group  authorizes and directs Agent to enter into this  Agreement,
and the other Loan Documents relating to the Collateral,  for the benefit of the
Lender  Group.  Each member of the Lender  Group agrees that any action taken by
Agent  in  accordance  with the  terms  of this  Agreement,  or the  other  Loan
Documents relating to the Collateral and the exercise by Agent of its powers set
forth  therein or herein,  together  with such other powers that are  reasonably
incidental thereto, shall be binding upon all of Lenders.

         16.17   Field   Audits  and   Examination   Reports;   Confidentiality;
Disclaimers by Lenders;  Other Reports and  Information.  By becoming a party to
this Agreement, each Lender:

               (a) is deemed to have  requested  that Agent furnish such Lender,
promptly after it becomes  available,  a copy of each field audit or examination
report  (each a "Report"  and  collectively,  "Reports")  prepared  by or at the
request of Agent, and Agent shall so furnish each Lender with such Reports,


               (b)  expressly  agrees and  acknowledges  that Agent does not (i)
make any  representation  or warranty as to the  accuracy of any Report and (ii)
shall not be liable for any information contained in any Report,

               (c) expressly  agrees and  acknowledges  that the Reports are not
comprehensive  audits or examinations,  that Agent or other party performing any
audit or examination will inspect only specific  information  regarding Borrower
and will rely  significantly  upon the Books, as well as on  representations  of
Borrower's personnel,

               (d)   agrees,   for  the   benefit  of  the  Lender   Group  and,
notwithstanding  Section 16.1,  the Loan Parties,  to keep all Reports and other
material,  non-public  information  regarding  Borrower and its Subsidiaries and
their  operations,  assets,  and existing and  contemplated  business plans in a
confidential  manner;  it being  understood  and agreed by Borrower  that in any
event such Lender may make  disclosures  (a) to counsel for and other  advisors,
accountants  and auditors to such Lender,  (b)  reasonably  required by any bona
fide  potential  or  actual  Assignee  or  Participant  in  connection  with any
contemplated  or actual  assignment  or  transfer  by such Lender of an interest
herein or any participation  interest in such Lender's rights hereunder,  (c) of
information  that has become  public by  disclosures  made by Persons other than
such Lender,  its Affiliates,  assignees,  transferees or Participants or (d) as
required or  requested  by any court,  governmental  or  administrative  agency,
pursuant  to any  subpoena  or other  legal  process,  or by any  law,  statute,
regulation  or court  order;  provided,  however,  that,  unless  prohibited  by
applicable law,  statute,  regulation,  or court order, such Lender shall notify
Borrower of any request by any court  governmental or administrative  agency, or
pursuant  to any  subpoena or other legal  process  for  disclosure  of any such
non-public material information concurrent with, or where practicable,  prior to
the disclosure thereof, and

               (e) without limiting the generality of any other  indemnification
provision  contained in this Agreement,  agrees: (i) to hold Agent and any other
Lender preparing a Report harmless from any action the  indemnifying  Lender may
take or conclusion the indemnifying  Lender may reach or draw from any Report in
connection with any loans or other credit  accommodations  that the indemnifying
Lender  has  made  or  may  make  to  Borrower,  or  the  indemnifying  Lender's
participation  in, or the indemnifying  Lender's purchase of, a loan or loans of
Borrower, and (ii) to pay and protect, and indemnify, defend and hold Agent, and
any such other Lender preparing a Report harmless from and against,  the claims,
actions,  proceedings,  damages,  costs, expenses, and other amounts (including,
attorneys fees and costs) incurred by Agent and any such other Lender  preparing
a Report as the direct or indirect  result of any third parties who might obtain
all or part of any Report through the indemnifying Lender.

         In  addition  to the  foregoing:  (x) any  Lender may from time to time
request of Agent in  writing  that  Agent  provide to such  Lender a copy of any
report  or   document   provided   by  Borrower  to  Agent  that  has  not  been
contemporaneously provided by Borrower to such Lender, and, upon receipt of such
request,  Agent promptly shall provide a copy of same to such Lender, (y) to the
extent that Agent is entitled,  under any  provision of the Loan  Documents,  to
request  additional  reports or information from Borrower,  any Lender may, from
time to time,  reasonably  request  Agent to exercise such right as specified in
such  Lender's  notice to Agent,  whereupon  Agent  promptly  shall  request  of



Borrower the  additional  reports or  information  reasonably  specified by such
Lender, and, upon receipt thereof from Borrower,  Agent promptly shall provide a
copy of same to such Lender,  and (z) any time that Agent  renders to Borrower a
statement regarding the Loan Account,  Agent shall send a copy of such statement
to each Lender.

         16.18 Several Obligations;  No Liability.  Notwithstanding that certain
of the Loan Documents now or hereafter may have been or will be executed only by
or in  favor of Agent  in its  capacity  as such,  and not by or in favor of the
Lenders,  any and all  obligations on the part of the Lenders to make any credit
available  hereunder shall constitute the several (and not joint) obligations of
the  respective  Lenders  on a  ratable  basis,  according  to their  respective
Commitments,  to make an amount  of such  credit  not to  exceed,  in  principal
amount, at any one time outstanding, the amount of their respective Commitments.
Nothing  contained  herein  shall  confer  upon any Lender any  interest  in, or
subject any Lender to any liability for, or in respect of, the business, assets,
profits, losses, or liabilities of any other Lender. Each Lender shall be solely
responsible for notifying its  Participants of any matters  relating to the Loan
Documents  to the extent any such notice may be  required,  and no Lender  shall
have any obligation,  duty, or liability to any Participant of any other Lender.
Except as provided in Section 16.7, no member of the Lender Group shall have any
liability for the acts or any other member of the Lender Group.  No Lender shall
be  responsible  to  Borrower  or any other  Person for any failure by any other
Lender to fulfill its  obligations to make credit  available  hereunder,  nor to
advance for it or on its behalf in connection with its  Commitment,  nor to take
any other action on its behalf  hereunder or in  connection  with the  financing
contemplated herein.

     17. JUDGMENT CURRENCY.

         17.1  Deficiency.  If, for the  purposes of  obtaining  judgment in any
court or any other  related  purpose  hereunder,  it is  necessary to convert an
amount  due  hereunder  in  the  currency  in  which  it is due  (the  "Original
Currency") into another currency (the "Second  Currency"),  the rate of exchange
applicable  will be the daily noon day rate  quoted by the Bank of Canada on the
relevant  date to purchase in Calgary,  Alberta the Original  Currency  with the
Second  Currency and  includes any premium and costs of exchange  payable by the
purchaser  in  connection  with such  purchase.  Each Party (the "First  Party")
agrees that its  obligations in respect of any Original  Currency due from it to
another Party  hereunder  will,  notwithstanding  any judgment or payment in the
Second  Currency,  be  discharged  only to the extent  that on the  Banking  Day
following  the  receipt  of any sum so paid in the  Second  Currency,  the other
Parties  may, in  accordance  with normal  banking  procedures,  purchase in the
Calgary,  Alberta foreign exchange market the Original  Currency with the amount
of the second  Currency so paid;  and if the amount of the Original  Currency so
purchased is less than the amount originally due in the Original  Currency,  the
First  Party  agrees  that the  deficiency  will be a  separate  and  continuing
obligation of it,  independent  from its obligations  under this Agreement,  and
will  constitute  in favour of the other  Parties a cause of action  which  will
continue in full force and effect notwithstanding any such judgment, or order to
the contrary, and the First Party agrees,  notwithstanding any such judgment, or
order to the  contrary,  and the First Party  agrees,  notwithstanding  any such
payment or judgment,  to indemnify  the other  Parties  against any such loss or



deficiency.  The Borrower  acknowledges  and agrees that any Indebtedness it may
incur or suffer  under this  Section 17 will be secured by the  Security  unless
earlier discharged as provided herein.

         17.2 Excess. The Lenders through the Agent will pay to the Borrower the
amount,  if any,  after  netting out all amounts due by the Borrower  hereunder,
which the Lenders may realize in excess of what is owed to them by virtue of the
conversion of the Original Currency into the Second Currency.

     18. GENERAL PROVISIONS.

         18.1  Effectiveness.   This  Agreement  shall  be  binding  and  deemed
effective  when executed by Borrower,  Agent and each Lender whose  signature is
provided for on the signature pages hereof.

         18.2 Section Headings.  Headings and numbers have been set forth herein
for  convenience  only.  Unless  the  contrary  is  compelled  by  the  context,
everything contained in each Section applies equally to this entire Agreement.

         18.3  Interpretation.  Neither this  Agreement nor any  uncertainty  or
ambiguity  herein  shall be  construed  against  the Lender  Group or  Borrower,
whether  under any rule of  construction  or otherwise.  On the  contrary,  this
Agreement  has  been  reviewed  by  all  parties  and  shall  be  construed  and
interpreted  according  to the  ordinary  meaning  of the  words  used  so as to
accomplish fairly the purposes and intentions of all parties hereto.

         18.4 Severability of Provisions. Each provision of this Agreement shall
be severable  from every other  provision of this  Agreement  for the purpose of
determining the legal enforceability of any specific provision.

         18.5  Amendments in Writing.  This  Agreement  only can be amended by a
writing signed by Agent (on behalf of the requisite Lenders) and Borrower.

         18.6  Counterparts;  Telefacsimile  Execution.  This  Agreement  may be
executed  in any number of  counterparts  and by  different  parties on separate
counterparts,  each of which, when executed and delivered, shall be deemed to be
an original, and all of which, when taken together, shall constitute but one and
the same  Agreement.  Delivery of an executed  counterpart  of this Agreement by
telefacsimile or electronic mail shall be equally as effective as delivery of an
original  executed  counterpart  of this  Agreement.  Any  party  delivering  an
executed  counterpart of this Agreement by telefacsimile or electronic mail also
shall deliver an original executed counterpart of this Agreement but the failure
to deliver  an  original  executed  counterpart  shall not affect the  validity,
enforceability,  and binding effect of this Agreement. The foregoing shall apply
to each other Loan Document mutatis mutandis.

         18.7 Revival and  Reinstatement  of  Obligations.  If the incurrence or
payment of the  Obligations  by Borrower  or  Guarantor  or the  transfer to the
Lender Group of any property  should for any reason  subsequently be declared to
be void or  voidable  under any state or  federal  law  relating  to  creditors'
rights,  including  provisions of the  Bankruptcy  Codes  relating to fraudulent



conveyances,  preferences or other voidable or recoverable  payments of money or
transfers of property (collectively,  a "Voidable Transfer"),  and if the Lender
Group is required to repay or restore,  in whole or in part,  any such  Voidable
Transfer, or elects to do so upon the reasonable advice of its counsel, then, as
to any such Voidable  Transfer,  or the amount  thereof that the Lender Group is
required  or  elects  to  repay  or  restore,  and as to all  reasonable  costs,
expenses,  and attorneys fees of the Lender Group related thereto, the liability
of  Borrower  or  Guarantor  automatically  shall be  revived,  reinstated,  and
restored and shall exist as though such Voidable Transfer had never been made.

         18.8  Integration.   This  Agreement,  together  with  the  other  Loan
Documents,  reflects the entire understanding of the parties with respect to the
transactions  contemplated  hereby and shall not be contradicted or qualified by
any other agreement, oral or written, before the date hereof.
