Re:      GAS CONSULTANT REVIEW OF GAS CONTRACT MODIFICAITONS

Ladies and Gentlemen:

C.C. Pace  Resources  ("Pace") has reviewed the Second  Amended and Restated Gas
Purchase  Contract between  Paramount  Resources Ltd.  ("Paramount") and Selkirk
Cogen Partners,  L.P. ("Selkirk"),  dated as of May 6, 1998, ("Revised Paramount
Contract") and the other Gas Contract Modifications1 and the risk issues related
to the Gas Contract  Modifications  in our role as Fuel Consultant under the May
1, 1994 Trust  Indenture  (the  "Indenture").  Pace hereby  certifies  to you as
follows:

1.   The  undersigned  officer  of Pace  is its  Authorized  Representative  (as
     defined in the Indenture),  has read the provisions of Sections  6.20(a)(i)
     and 6.20(c)(i)  and related  definitions of the Indenture and has made such
     examination or investigation as is necessary to enable the expression of an
     informed  opinion  as to the  matters  addressed  in this Gas  Consultant's
     Certificate.

2.   Pace finds, and concurs with the Partnership's  determination,  pursuant to
     Sections  6.20(a)(i)  and  6.20(c)(i)  of the  Indenture  as set  forth  in
     Attachment  B, that the  implementation  of the Gas Contract  Modifications
     could not reasonably be expected to result in a "Material  Adverse  Change"
     within  the  meaning  of the  Indenture  ("No  MAC")  and,  to  the  extent
     applicable,  would not impair the ability of the Partnership to perform its
     obligations  under  the  other  Project   Agreements  (as  defined  in  the
     Indenture).

- ---------------------------
1  For   purposes  of  this  Gas   Consultant's   Certificate,   "Gas   Contract
Modifications"  means and includes the  execution,  delivery and  performance by
Selkirk of the Revised  Paramount  Contract and the other  agreements  listed on
Attachment   A  to  this  Gas   Consultant's   Certificate.   The  Gas  Contract
Modifications  are being undertaken in connection with the  restructuring of the
current Unit 1 power purchase agreement between Selkirk and Niagara Mohawk Power
Corporation ("NiMo") pursuant to the master Restructuring  Agreement dated as of
July 9, 1997 among NiMo, Selkirk and other IPP's (the "NiMo restructuring").

This finding is predicated on the NiMo restructuring and on specific  provisions
contained  in the  Amended  and  Restated  Power  Purchase  Agreement  with NiMo
("Amended  PPA"),  which are  under the  Indenture  purview  of the  Independent
Engineer.  The scope of our analysis as Gas  Consultant  is to opine,  given the
changes  in the  Amended  PPA,  on  the  proposed  change  in  the  fuel  supply
arrangement.

In summary,  Pace bases its No MAC  determination  on the following  conclusions
regarding the Gas Contract Modifications:

 .  Contracted firm supply of 16,400 Mcf/day under the Revised Paramount Contract
   is adequate to meet the maximum requirements of Unit 1.

 .  Strong linkage exists between natural gas costs and power revenues due to the
   use of an  identical  natural gas spot price  index in the Revised  Paramount
   Contract and the Amended PPA.

 .  Sufficiently  secure  firm gas supply is assured  through  spot  market-based
   pricing near the Western Canada gas production  area and reserve  dedication,
   liquidated damages, and additional Paramount obligations.

 .  Paramount's  obligations  are well  supported by  Paramount's  financial  and
   market position.

 .  Required  regulatory  approvals of the Revised  Paramount  Contract have been
   obtained.

Attachment C summarizes Pace's analysis supporting these findings.


IN  WITNESS  WHEREOF,   the  undersigned  has  executed  this  Gas  Consultant's
Certificate as of the date first written above.

Ladies and Gentlemen:


          This  Officer's  Certificate  is being  delivered by the  undersigned,
Selkirk   Cogen   Partners,   L.P.,   a  Delaware   limited   partnership   (the
"Partnership"),  pursuant to Section 6.20 of the Trust Indenture dated as of May
1, 1994 among the  Partnership,  Selkirk Cogen Funding  Corporation  and Bankers
Trust Company, as Trustee (the "Indenture").

          The  Partnership  has entered into the following  transactions,  which
collectively  are  referred  to in this  Officer's  Certificate  as the  "Unit l
Restructuring":  (1) the  restructuring  of the NIMO  Power  Purchase  Agreement
between the Partnership and NIMO pursuant to the Master Restructuring  Agreement
dated as of July 9,  1997  among  NIMO,  the  Partnership  and other  IPP's,  as
amended, (2) the execution, delivery and performance of the agreements listed on
Exhibit A to this  Officer's  Certificate,  and (3) the  completion of the other
transactions  listed on Exhibit A. Capitalized terms used and not defined herein
shall  have  the  meanings  assigned  to  such  terms  in  Exhibit  A and in the
Indenture.

          The Partnership hereby certifies to you as follows:

          1.   The  undersigned  officer  of JMC  Selkirk,  Inc.,  the  Managing
               General Partner, is its Authorized  Representative,  has read the
               provisions  of  Section  6.20  and  related  definitions  of  the
               Indenture and has reviewed the documents  which comprise the Unit
               1 Restructuring  and made such other examination or investigation
               as is necessary to enable the  Partnership to express an informed
               opinion  as  to  the   matters   addressed   by  this   Officer's
               Certificate.

          2.   The implementation of the Unit 1 Restructuring, including (a) the
               execution,  delivery and  performance of the Amended and Restated
               NIMO Power Purchase Agreement, the Amended Paramount Contract and
               the Amended  TransCanada  Agreement,  and the  termination of the
               NIMO  License  Agreement,  could not  reasonably  be  expected to
               result in a  Material  Adverse  Change.  As  required  by Section
               6.20(a)(i) of the

                                      B-1


               Indenture,  the foregoing  determination is concurred with by the
               Independent  Engineer in the Independent  Engineer's  Certificate
               addressed  to you and dated  August 31,  1998,  executed  by R.W.
               Beck, Inc. (the "Independent  Engineer's  Certificate") and, with
               respect  to  the  Amended  Paramount  Contract  and  the  Amended
               TransCanada   Agreement,   by  the  Gas  Consultant  in  the  Gas
               Consultant's  Certificate  addressed  to you and dated August 28,
               1998,  executed by C.C.  Pace  Resources  (the "Gas  Consultant's
               Certificate").

          3.   After  giving  effect  to  the   implementation  of  the  Unit  1
               Restructuring,  including the execution, delivery and performance
               of the Amended and Restated NIMO Power  Purchase  Agreement,  the
               Amended Paramount Contract and the Amended TransCanada Agreement,
               and the  termination of the NIMO License  Agreement,  the minimum
               annual  Projected Debt Service Coverage Ratio will be equal to or
               exceed  1.5:1  and the  average  annual  Projected  Debt  Service
               Coverage  Ratio for the remaining term of the Bonds will be equal
               to or exceed  1.75:1.  As required by Section  6.20(a)(ii) of the
               Indenture,  the foregoing  determination is concurred with in the
               Independent Engineer's  Certificate.  The full calculation of the
               Projected Debt Service  Coverage Ratio  (together with supporting
               documentation)  is set forth in  Attachment B to the  Independent
               Engineer's Certificate.

          4.   The Partnership's  entering into the Additional  Contracts listed
               on  Exhibit A could not  reasonably  be  expected  to result in a
               Material  Adverse  Change and would not impair the ability of the
               Partnership  to perform its  obligations  under the other Project
               Agreements.  As required by Section  6.20(c)(i) of the Indenture,
               the foregoing  determination is concurred with in the Independent
               Engineer's  Certificate and, to the extent such matters relate to
               the   Partnership's   fuel  supply,   in  the  Gas   Consultant's
               Certificate.

          5.   The  Partnership  will be furnishing to the Collateral  Agent the
               Ancillary Documents related to the Additional Contracts listed on
               Exhibit A within a  reasonable  period,  to the  extent  required
               under Section 6.20(c)(i)(B) of the Indenture. The Partnership was
               unable to obtain a Consent or Opinion of Counsel  with respect to
               the other IPP parties to the MRA or to the  Allocation  Agreement
               using commercially reasonable efforts, due to the large number of
               Persons involved.

          6.   With respect to each of the transactions  which comprise the Unit
               1 Restructuring,  the Partnership has complied with the covenants
               set  forth  in  Section  6.20 of the  Indenture,  and no Event of
               Default under this Indenture has occurred and is continuing.

                     ANALYSIS OF GAS CONTRACT MODIFICATIONS


Volume

Pace has  determined  that the Revised  Paramount  Contract total firm volume of
16,400  Mcf per day  ("Revised  MDQ") is  sufficient  to meet the  maximum  fuel
requirements  of Unit 1. The Revised MDQ  reflects a 6,600 Mcf  reduction in the
original quantity of 23,000 Mcf, which is due to a long-term assignment of 6,000
Mcf of Selkirk  transportation  capacity on TransCanada  PipeLines to Paramount.
Pace reviewed the long-term assignment and we find that the long-term assignment
would not likely introduce additional project risk.

The  primary  reasons  for this  finding  are that under the  Amended  PPA it is
Selkirk's  option  whether to run Unit 1 (except for the Call  Option  discussed
directly  below) and that  availability  requirements  have been struck from the
agreement.  Therefore,  Pace  concludes  that  Selkirk  can be expected to lower
electrical output of Unit 1 to match the available gas supply, without incurring
penalty or losses in capacity revenues.

The NiMo Call  Option  creates  an  obligation  for Unit 1 to  generate  certain
specified  amounts of electricity.  The Call Option exists only during the first
two years of the Amended PPA or until the SC-6 period expires,  whichever occurs
sooner. The Independent Engineer has calculated the maximum net incremental fuel
requirement  under the Unit 1 Call Option to be  approximately  9,800  MMBtu/day
based on winter ambient conditions and full load electric  generation of Unit 2.
Pace finds that Selkirk's firm gas supply under the Revised  Paramount  Contract
is more than sufficient to meet the maximum fuel requirement of the Call Option.

Additional  supporting  reasons for this finding  include the following  sources
available to Selkirk to supplement the firm contract gas supply:

1.   Selkirk could reliably  acquire spot natural gas supplies during summer and
     shoulder  periods  to  supplement  the firm  contract  supply  and spot gas
     supplies during these periods can be relied upon over the long-term.
2.   Selkirk can expect a maximum of 2%  tolerance  in  Tennessee  Gas  Pipeline
     daily  delivery  tolerances  for  long-term  planning  purposes.  Based  on
     Selkirk's  supply  of  70,000  Mcf  of  firm  capacity  on  Iroquois,  this
     flexibility would provide an additional 1,400 Mcf/day.
3.   The NiMo inadvertent  account  established by separate contract can be used
     to lower electric  output by 5 MW without penalty or reduction in revenues.
     Based on verification by the Independent  Engineer,  this provision results
     in fuel savings of 1,000 Dt/day.

- --------------------------------------------------------------------------------
                                      C-1



Price

The Revised Paramount  Contract price is based on a published  Empress,  Alberta
monthly spot price index.  The index is identical to the gas price  component in
the  Amended PPA except that the revenue  index is  multiplied  by 105  percent,
which benefits the project (the gas price component in the Amended PPA under the
Call Option is discussed  directly below). The Amended PPA price components have
been  verified  by the  Independent  Engineer.  Pace  finds that the use of this
identical gas price index creates strong linkage between  Selkirk's gas cost and
NiMo electric sales revenue.  In addition,  corresponding to the fixed nature of
the Amended  PPA,  gas  contract  price  re-determination  provisions  have been
removed  under the Revised  Paramount  Contract.  For these reasons and due to a
potential,  slight de-linkage risk under the original  Paramount Contract index,
linkage may be improved under the Revised Paramount Contract.

The Amended PPA gas price  component under the Call Option is based on published
New York market area spot gas index  prices.  Pace finds the use of the New York
indices  beneficial  to Selkirk  because the New York indices  should  always be
higher than the Empress,  Alberta index used in the gas supply  contract and the
use of the New York  indices  should  approximate  the  resale  prices  at which
Selkirk would have resold the Paramount gas supply if NiMo had not exercised the
Call Option.

Supply Security

Under the  Revised  Paramount  Contract,  assurance  of supply is  derived  from
dedicated reserves and liquidated damages that materially  obligate Paramount to
perform.  These same factors were also the primary  elements of supply  security
under the original  Paramount  Contract.  Pace finds that although the dedicated
reserve  provisions have been modified under the Revised  Paramount  Contract so
that Paramount may produce for any purpose from the dedicated  lands, the supply
security under the Revised Paramount Contract is sufficient due to the following
factors:

1.   The Revised Paramount Contract spot-market,  production-area-based  natural
     gas pricing terms make a SAP claim highly unlikely.
2.   The liquidated damages provided in the event Paramount fails to deliver the
     nominated  quantity  up to the  Revised  MDQ  are  large  and  the  Revised
     Paramount Contract also requires Paramount to make available to the project
     its transportation rights on NOVA, which provides access to alternative gas
     supplies.
3.   The  current  reserve  and  deliverability  status of the  dedicated  lands
     indicates  far greater  natural gas supply  capability  than is required to
     meet the reserve dedication contract requirements.
4.   The Revised Paramount Contract permits Paramount, under certain conditions,
     to deliver other gas supplies ("Alternate Sources"),  which gives Paramount
     more  flexibility to fulfill the Selkirk  contract and lowers the risk of a
     SAP claim.

- --------------------------------------------------------------------------------
                                      C-2


Pace  finds  that the risk of a SAP  claim is  significantly  reduced  under the
Revised Paramount  Contract because the contract commodity price is set to equal
a monthly spot market price near the Western Canadian production area applicable
to Paramount's gas supply. The potential for a SAP claim is nearly ruled out for
practical  purposes since the market-set price for natural gas in the production
area should  permit  producers to fully  recover all finding,  development,  and
replacement costs. While this may not be true at certain times due to short-term
market volatility and market disruptions, it is likely over the long run and the
SAP claim requires a determination five years in the future.

Security of supply is enhanced by the significant  liquidated  damages Paramount
faces in the event  Paramount  fails to deliver.  The project has an  additional
remedy in the event of Paramount  delivery  failure under the Revised  Paramount
Contract to use Paramount's NOVA  transportation to acquire supply at the AECO-C
market hub and deliver this gas to Empress.  Under this  scenario,  AECO-Empress
basis  pricing  risk would exist,  namely that gas prices at AECO would  diverge
from prices at Empress to the  detriment of the  project.  Pace finds that since
Selkirk  would  only be  charged  with the  commodity  cost  portion of the NOVA
transportation, AECO-Empress basis pricing risk is sufficiently mitigated.

In  addition,   Pace  finds  that  the  current   status  of  the  reserves  and
deliverability   capability   of  the   dedicated   lands  exceed  the  contract
requirements.  Pace reviewed the August 21, 1997 McDaniel reserve report and the
Gilbert  Lausten  October  1, 1997 audit of the  McDaniel  report.  In  summary,
approximately  98 Bcf of  reserves  remained  available  to  serve  the  Selkirk
contract as of November 1, 1997.  The total contract  requirements  based on the
Revised MDQ from  November 1, 1997 to the end of the primary term on November 1,
2007 are  approximately  60 BCF,  well under the estimated  remaining  reserves.
Similarly,  the deliverability based on the 1997 reserve report was adequate and
under  the  Revised  MDQ the  amount  of excess  deliverability  from  currently
producing fields would increase and extend into 2002.

Pace also examined  whether  Paramount could rapidly deplete the reserves in the
dedicated lands by maximizing  production and selling gas to other parties.  The
McDaniel's  report indicated the maximum possible  production from the dedicated
lands to be approximately 21 Bcf from November 1, 1997 through October 31, 1998.
McDaniel's  estimated  maximum  production  declines over time  consistent  with
normal field depletion characteristics.  Therefore, it would take more than four
and one-half  years to fully deplete the remaining  reserves even at the maximum
possible production rates providing ample advance notice of a reserve deficiency
that Paramount would be required to cure.

Finally,  in the unlikely event that the market-set price at Empress falls below
Paramount's  replacement costs, the Alternate Sources provision further enhances
supply  security.  Pace believes that  Paramount  could be expected to serve the
contract even in the case of an extended  collapse in Empress spot market prices
by acquiring "low" priced alternative gas supply in the marketplace.

PARAMOUNT FINANCIAL AND MARKET POSITION

Paramount's sound financial condition,  operating record, and growing asset base
provide  additional  comfort that  Paramount  can fulfill the Revised  Paramount
Contract.  Paramount boasts record operational and financial results in its 1997
Annual Report and its 1998 First Quarter Report.  Increased  production  coupled
with strong  commodity prices resulted in substantial  increases in revenue.  In
1997, Paramount's revenues increased 28 percent to $128 million.  Production for
the first  quarter 1998 rose 63 percent or 204 MMcf per day compared to the same
period for 1997.  Finally,  Paramount's  proven gas reserves have increased each
year since 1993 and reached 481.7 Bcf in 1997.

In addition,  trends in Paramount's gas sales portfolio  indicate that Paramount
will likely  have  market  incentives  to perform  under the  Revised  Paramount
Contract.  Selkirk's  share of  Paramount's  total  gas  sales  volume  has been
declining  over the past  several  years and sales to Selkirk  represented  11.1
percent of 1997 total  Paramount gas sales. A growing share of  Paramount's  gas
sales is  comprised  of spot market  volumes.  For  example,  spot market  sales
represented 38 percent of total sales in 1997 compared to 23 percent of sales in
1996.  Spot market sales now  represent an  important  component of  Paramount's
total  marketing  portfolio  and much of the spot volume is sold at Alberta spot
prices similar in nature to the pricing in the Revised Paramount Contract.

REGULATORY APPROVALS

Finally,  the  required  Canadian  and  U.S.  government   regulatory  approvals
pertaining to the Revised  Paramount  Contract have been obtained.  The National
Energy  Board  (Canada)  provided  its approval in a July 7, 1998 letter and the
Department of Energy (United States) acknowledged  Selkirk Cogen Partners,  L.P.
had met the notification  requirements  related to amendments to arrangements to
import natural gas in correspondence dated July 15, 1998.
