Re:      Results of Independent Engineer's Review
         Restructuring of Phase I
         Selkirk Cogeneration Facility


Ladies and Gentlemen:

In our capacity as Independent  Engineer under the Indenture  (defined below) we
have  performed  a review of the  impact of the Phase I  Restructuring  (defined
below)  on the  Selkirk  Project  projected  economics.  For  purposes  of  this
Independent  Engineer's  Certificate "Phase I Restructuring"  means and includes
the following  transactions:  (1) the restructuring of the current Phase I power
purchase  agreement  ("Existing PPA") between Selkirk Cogen Partners,  L.P. (the
"Partnership")  and Niagara Mohawk Power  Corporation  ("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  Attachment  A to  this  Independent
Engineer's Certificate,  and (3) the completion of the other transactions listed
on Attachment A.  Capitalized  terms used and not defined  herein shall have the
meanings assigned to such terms in Attachment A and in the Trust Indenture dated
as of May 1, 1994 among Selkirk Cogen Funding  Corporation,  the Partnership and
Bankers Trust Company, as Trustee (the "Indenture").

R. W. Beck, Inc., the Independent Engineer under the Indenture, hereby certifies
to you as follows:

         1.   The  undersigned  officer of R. W. Beck,  Inc.  is its  Authorized
              Representative, has read the provisions of Sections 6.20(a)(i) and

          2.   Our  analyses  focused  on  the  preparation  and  comparison  of
               projected  economics  through the terms of the bonds for the case
               with the  Existing  PPA and the case that would  result  from the
               proposed  Phase  I  Restructuring.   For  both  cases,  projected
               economics  were prepared  utilizing  the Selkirk Cogen  Partner's
               Long-Term  Production  Model  which  is  the  model  used  in the
               preparation of the Annual Independent Engineer's Report delivered
               to  the  Trustee  under  the  Indenture.   However,   the  Annual
               Independent   Engineer's   Reports  are   prepared   utilizing  a
               short-term (i.e.,  monthly) model for the first two years,  which
               was not necessary as part of these analyses.  Further, as part of
               our  analyses,  the projected  economics  presented in the Annual
               Independent Engineer's Report dated November 1997 (i.e., with the
               Existing  PPA),  were  updated  to reflect  recent  and  proposed
               assumptions  by the  Partnership.  The  resultant  case  with the
               Existing  PPA is referred to herein as the  "Existing  PPA Case."
               The  projected  economics  for  the  Phase I  Restructuring  (the
               "Amended PPA Case")  include  modeling the impact of the proposed
               Amended  PPA,  as  well as the  resultant  changes  to  projected
               electric dispatch and operating expenses.

               We have not  reviewed  the  Selkirk  Project  Agreements  for gas
               supply and  transportation  including those Phase I Restructuring
               agreements  indicated as numbers 5, 6, 7, and 8 on  Attachment A,
               but have  relied  upon the  review  of the  fuel  agreements  and
               projections  of the Selkirk  Cogeneration  Facility fuel costs as
               reviewed by the Gas  Consultant,  C. C. Pace.  The details of our
               comparative  analyses  are  described  in  Attachment  B to  this
               letter.

          3.   We believe  that the  projected  economics  for the two cases use
               reasonable  assumptions  consistent in all material respects with
               the  Selkirk  Project  Agreements  and the  historical  operating
               results of the project,  and that the  resultant  Projected  Debt
               Service   Coverage   Ratios  are  reasonable  in  light  of  such
               assumptions.

          4.   Subject  to the  foregoing  and  Attachment  B, we have  made the
               following determinations:

               .  We find,  and  concur  with the  Partnership's  determination
                  pursuant to Section 6.20(a)(i) and (c)(i) of the Indenture set
                  forth in Attachment C, that the  implementation of the Phase I
                  Restructuring  could not reasonably be expected to result in a
                  "Material   Adverse   Change"   within  the   meaning  of  the
                  Partnership's  Indenture and, to the extent applicable,  would
                  not  impair  the  ability of the  Partnership  to perform  its
                  obligations under the other Project Agreements.

                . We find,  and  concur  with the  Partnership's  determination
                  pursuant to Section  6.20(a)(ii) of the Indenture set forth in
                  Attachment  C,  that,  after  giving  effect  to the  Phase  I
                  Restructuring,    the   debt   service   coverage   thresholds
                  established in the Indenture are satisfied -- a minimum annual

                  Projected Debt Service Coverage Ratio of at least 1.5:1 and an

                  remaining term of the Bonds of at least 1.75:1.

                                  ATTACHMENT B

Following  is a summary of the  detailed  analyses  utilized  in  preparing  the
Existing  PPA Case  and the  Amended  PPA  Case.  Also  attached  are Pro  Forma
summaries for each of the cases.

EXISTING PPA CASE

The  Existing  PPA  Case is  based  on the  assumption  that  the  overall  NiMo
restructuring  represented by the Master Restructuring  Agreement among NiMo and
certain IPP's (the "MRA") is not implemented. Further, the Existing PPA case was
prepared in order to reflect the Partnership's  updated assumptions in operation
and pricing conditions for each of Phases I and II from that which was projected
and included in our November 1997 Independent  Engineers Report (the "IER"). The
changes between the IER conditions and assumptions  include the following items:
(1) a  reduction  in the O&M Fee after year 2000;  (2) an  increase in the steam
demand from GE; (3) Phase I gas capacity  release through the term of the Bonds;
(4) additional  gas peak shaving for Phase I; (5) additional gas  transportation
revenue,   and;   (6)  changes  in  the  Iroquois   transportation   demand  and
transportation commodity costs for Phase I and Phase II. The assumptions related
to gas were reviewed and concurred with by C.C. Pace, the Fuel Consultant.

Basic   assumptions  used  in  the  Projected   Operating   Results,   including
availability,  fuel pricing, and dispatch reflect assumptions  commensurate with
long-term projections.

AMENDED PPA CASE

The July 29, 1998 draft of the Amended and  Restated  Power  Purchase  Agreement
between NiMo and the  Partnership  (the "Amended  PPA") provides for the project
term to be reduced to 10 years from June 30,  1998.  The  Existing PPA is set to
expire on April 16, 2012.  Under the terms of the Amended PPA that contract will
expire on June 30, 2008.

The Amended PPA provides for revenues to be  compressed  into a shorter term and
includes a monthly  contract payment  ("Monthly  Contract  Payment"),  the fixed
portion of which is payable by NiMo, regardless of the operation of Phase I. The
variable portion of the Monthly Contract Payment is based on energy and capacity
actually  sold to NiMo under the  Amended  PPA.  The  Monthly  Contract  Payment
consists of four indexed  pricing  components;  the capacity  component  and the
fixed portion of the energy component are offset by actual market prices. Market
prices  will  be  established  by  the  marketplace  in  conjunction   with  the
Independent  System  Operator  and/or Power  Exchange  ("ISO/PE") for each of 11
regions within New York State.  Market prices will be determined  based on daily
bids for quantity  and price of energy as put by each willing  supplier and will
establish the price at which each generator will be paid for energy  supplied to
the region. Prior to the establishment of such market prices, the initial market
pricing for energy will be a proxy market price based on NiMo's tariff for power
purchases from QF's.

The Amended PPA also provides that the Selkirk  project may require NiMo to take
and purchase defined quantities of energy and capacity, at market prices, during
the period before the ISO/PE is fully  functional.  This energy and capacity may
be produced by Phase I, Phase II or third party sources. NiMo also has the right
to call Phase I's energy and capacity,  up to the defined  contract  quantities,
during the period prior to the

Page 2

implementation  by the ISO/PE of market pricing (or 24 months,  if earlier).  If
NiMo exercises this right, the purchase price will be the greater of the initial
market price or the project's variable costs of production.

As a result of the MRA many of the power purchase agreements which NiMo has with
NUGs will be restructured or bought out. Therefore, the level of dispatch of the
remaining  units  including  Selkirk Phase I and Phase II will be modified.  The
Partnership  has provided a dispatch  analysis  conducted  by Slater  Consulting
which models the dispatch of Selkirk's  Phases I and II after the  restructuring
in New York State.  Dispatch factors increased from that assumed in the Existing
PPA  Case,  principally  due to the  retirement  of  approximately  1,050  MW of
existing  NUG  units.  Slater's  analysis  also  includes  a  market  price  for
electricity after restructuring which is the projected price for electricity for
the  region in which  the  Selkirk  facility  is  located.  The  "Market  Price"
projected  by Slater  has been  used in  pricing  both the  fixed  and  variable
portions of the energy component of the monthly contract payment.

The higher  dispatch  projections  for  Selkirk  Phase I and II will result in a
change in the schedule of major  maintenance  expenditures;  therefore,  we have
estimated a revised schedule of major maintenance deposits.

We believe that the non-fuel operating and maintenance  expenses for the Amended
PPA Case will not increase  materially over those for the Existing PPA Case, and
therefore have not revised their costs for the Amended PPA Case. We examined the
impact of a marginal  increase  to normal  non-fuel  operating  and  maintenance
expenses and find that it has little impact on the debt service  coverage  ratio
for the Amended PPA Case.


         REVENUES

The Amended PPA provides the Partnership three potential sources of revenue. The
first  revenue  source  will be  Monthly  Contract  Payments  to be paid by NiMo
regardless  of Phase I  output,  except in the event  that the  Market  Price or
Market Capacity Price (which offset the capacity component and the fixed portion
of the energy  component) are so high as to reduce the Monthly  Contract Payment
below zero. In such case the Partnership  would be obligated to make payments to
NiMo.

The Partnership has two options for augmenting the fixed portions of the Monthly
Contract Payment:  (1) it can exercise its option, prior to the establishment of
a fully  functioning  ISO/PE  to  require  NiMo to take and  purchase  up to the
contract  quantity of energy or  capacity,  at the Market  Energy  Price  ("Sale
Option"); and (2) in lieu of or in addition to sales to Nimo, it can make market
sales of Phase I energy or  capacity.  In 1998 there is an  additional  one-time
adjustment  which  represents  revenue to  Selkirk  in 1998  only.  A new set of
inputs,  as described  below,  exists in the model which  addresses  the changed
revenue structure as proposed in the Amended PPA.

Contract  Quantities.  The Annual  Contract  Volumes  in MWh,  which are used to
calculate the fixed portions of the Monthly  Contract  Payment and establish the
maximum  quantities


Selkirk Cogen Partners, L.P.
August 27, 1998
Page 3

of energy  and  capacity  which NiMo can be  obligated  to  purchase  or Selkirk
obligated to sell, are as shown in Table 1. The Amended PPA specifies applicable
monthly  quantities  (the  "Monthly  Contract  Quantity")  based  on the  Annual
Contract Volumes.

                     9                                 473,400
                     10                                485,200
 .

MONTHLY CONTRACT   PAYMENTS The Monthly  Contract Payment is the sum of four (4)
components:  (1) a Capacity Payment; (2) an Energy Payment; (3) a Transportation
Payment; and (4) an Operation and Maintenance Payment. NiMo will be obligated to
pay the  Partnership  the monthly payment to the extent such number is positive,
and the  Partnership  will be obligated  to pay NiMo the monthly  payment to the
extent such number is negative.  In the Amended PPA Case,  this number is always
positive.

1.   The "Capacity  Payment" will be an amount equal to the  difference  between
     (A) the Contract Capacity Payment and (B) the Market Capacity Payment.

     A.   The  "Contract  Capacity  Payment"  will equal the  product of (i) the
          Contract  Capacity Rate, (ii) the Monthly Contract  Quantity and (iii)
          the DMNC Adjustment. The Contract Capacity Rates are as follows:






Selkirk Cogen Partners, L.P.
August 27, 1998
Page 4

                   Contract Year        Capacity Rate

                         1              $73.83/MWh
                         2              $73.60/MWh
                         3              $75.73/MWh
                         4              $75.76/MWh
                         5              $76.10/MWh
                         6              $76.45/MWh
                         7              $76.82/MWh
                         8              $77.23/MWh
                         9              $77.79/MWh
                        10              $78.42/MWh

         The DMNC Adjustment is a quotient, the numerator of which is the tested
         Phase I DMNC and the denominator of which is 79.9 MW.


          B.   The  "Market  Capacity  Payment"  will be an amount  equal to the
               product  of (x) the  Market  Capacity  Price  in $/MW and (y) the
               weighted averaged capacity  associated with the notional quantity
               of capacity  corresponding to the applicable  contract  quantity.
               The Market  Capacity  Price will be: (i) equal to zero during the
               period  prior to the  establishment  of the  ISO/PE  and any time
               thereafter  when no separate  capacity  market  exists;  and (ii)
               after the ISO/PE is established  and only if a separate  capacity
               market  exists,  equal to the market  price  paid to sellers  for
               capacity at the project's location.

2.   The "Energy  Payment"  will be equal to the sum of (A) the Contract  Energy
     Payment,  (B) the Delivered  Energy  Payment,  (C) the  Delivered  Capacity
     Payment and (D) the Call Energy Payment.

     A.   The "Contract  Energy  Payment" will be an amount equal to the product
          of (i) the difference between the Contract Energy Price and the Market
          Energy Price,  (ii) the Monthly  Contract  Quantity and (iii) the DMNC
          Adjustment. The Contract Energy Price for the first two Contract Years
          will be fixed as follows:  $15.80/MWh  for the first contract year and
          $15.95/MWh  for the second  contract year. In contract years 3 through
          10, the Contract  Energy Price will consist of the heat rate of 10,950
          MMBtu/MWh  multiplied by 105% of the current month's spot gas price at
          the Empress  border.  This spot gas price is  currently  assumed to be
          equal to the Pan Can Commodity  Negotiated T2 rate, times 10,950 MMBtu
          per MWh and is  estimated by the  Partnership  to be $18.25 per MWh in
          year    3    and     $19.70     per    MWh    in    year    4.

          The Market  Energy  Price is defined as the  locational  based  market
          price  ("LBMP") for energy for the next day which is applicable to the
          Selkirk  Project.  Prior to the  establishment  of the  ISO/PE and its
          implementation of LBMP pricing, the Market Energy Price will be NiMo's
          short-term  avoided energy and capacity costs, as stated in its tariff
          for the purchase of power from QF's ("SC-6 Rate").

     B.   The "Delivered  Energy Payment" will be an amount equal to the product
          of (i) the Delivered  Energy  Quantity  (which is the amount of energy
          actually sold to NiMo) and (ii) the Market Energy Price.

     C.   The "Delivered  Capacity  Payment" will be equal to the product of (i)
          the  Delivered  Capacity  Quantity  (which is the  amount of  capacity
          actually sold to NiMo) and (ii) the Market Capacity Price in $/MW.

     D.   The "Call  Energy  Payment"  will be equal to the  product  of (i) the
          Delivered Call Quantity  (which is the amount of energy  actually sold
          to NiMo in  connection  with its exercise of the Call Option) and (ii)
          the Call  Energy  Price in $/MW.  The Call  Energy  Price  will be the
          higher of the SC-6 rate and the project's  variable fuel and operation
          and maintenance cost of production.

3.   The "Transportation  Payment" will be an amount equal to the product of (A)
     the  Transportation  Price, (B) the Monthly  Contract  Quantity and (C) the
     DMNC Adjustment.  The Transportation Price for the first two contract years
     is fixed;  it will be $7.15/MWh in the first contract year and $7.35/MWh in
     the  second.  Beginning  on July 1 of the  year  2000 and  thereafter,  the
     Transportation Price will be equal to $7.15/MWh adjusted to reflect changes
     since July 1, 1998 in the consumer  price index for urban  consumers in New
     York-Northern New Jersey-Long Island ("CPI").

4.   The "Operation and Maintenance  Payment" will be the product of (A) the O&M
     Price, (B) the Monthly Contract  Quantity and (C) the DMNC Adjustment.  The
     O&M Price for the first two  contract  years will be fixed as  $6.70/MWh in
     the  first  contract  year  and  $6.89/MWh  in the  second  contract  year.
     Beginning  on July 1 of the year 2000 and  continuing  thereafter,  the O&M
     Price will be $6.70/MWh  adjusted to reflect  changes since July 1, 1998 in
     CPI.  For  purposes of this report we have assumed that the rate of general
     inflation is the same as  contained in the Existing PPA Case,  which is 3.1
     percent per year.

The pricing  components  are  summarized for each of the first five years of the
Amended PPA in Table 2.

For  purposes of this  analysis,  we have  utilized  the Slater  forecast of the
Market  Energy  Price,  which is the  clearing  price  for  energy  for Phase I.
Slater's  forecast  of the Market  Energy  Price is that  provided  to us by the
Partnership on March 19, 1998. The Market Energy Price as estimated by Slater is
summarized in Table 3.

Power Sales to NiMo and the Marketplace.  From the effective date of the Amended
PPA until an ISO/PE is established and fully  functioning,  the Partnership will
have  the  option  to sell  and  deliver  energy  and  capacity  to NiMo up to a
specified  Monthly  Contract  Quantity,  plus up to 5% of the  Monthly  Contract
Quantity.  NiMo will be required to take and pay for such energy and capacity as
the Partnership delivers to it under the Sale Option at the Market Energy Price,
and, if applicable, the Market Capacity Price.


Selkirk Cogen Partners, L.P.
August 27, 1998
Page 7


For any time-period  during which the Partnership  does not sell to NiMo, it may
sell such energy and  associated  capacity to third  parties,  provided  that it
first offers NiMo the  opportunity  to purchase  that energy and capacity at the
Market  Energy  Price,  and,  if  applicable,  the Market  Capacity  Price.  The
Partnership  is free to sell  energy  and  capacity  in  excess  of the  Monthly
Contract Quantity to third parties without giving NiMo a right of first refusal.


In the Amended PPA Case, Selkirk receives revenues from the exercise of the Sale
Option.  Additionally,  there is a market for the energy  generated from Phase I
which is in excess of the Monthly  Contract  Quantity.  Under  Slater's  revised
dispatch for the Amended PPA Case, in 1998 Phase I will  generate  approximately
624,892  MWh  assuming  capacity  of 79.9 MW,  availability  of 93 percent and a
dispatch of 96 percent. For purposes of this analysis,  we have assumed that all
of Phase I's  energy not sold to NiMo is sold to the  marketplace  at the Slater
forecasted Phase I Market Price.


Total  revenues from  projected  Phase I energy sales over the term of the Bonds
are shown in Table 4.

The Partnership may also choose to sell capacity to NiMo or to the  marketplace.
Assuming that the New York Power Pool does not have adequate capacity for either
existing load or to meet reserve requirements, Phase I capacity not sold to NiMo
may be sold to the  marketplace.  For purposes of the analysis,  we have assumed
that the notional  capacity  corresponding to the Monthly  Contract  Quantity is
fully committed to NiMo. Any excess capacity is calculated as the nominal rating
of the unit of 79.9 MW less the capacity sold to NiMo. In 1998,  the Amended PPA
calls  for Phase I to have a maximum  of 45 MW for sale to NiMo.  The  remaining
capacity of (79.9-45.0) 34.9 MW is assumed to be available for sale in 1998.

The market  capacity  price was estimated by Slater to be $3.2877 per MWh in the
fall of 1997.  This  price is used as the  revenue  basis for the sale of excess
capacity of Phase I. In 1998,  the  capacity of 34.9 MW is valued at $3.3896 per
MWh. The resulting  revenue to Selkirk is approximately  $1,036,279 in 1998. The
future capacity price is assumed to increase at the rate of general inflation of
3.1 percent per year.

1998  NIMO  SETTLEMENT  ADJUSTMENTS.  In  1998  there  are  additional  one-time
adjustments  to the  revenues  under  the NiMo  Settlement  Agreement  which the
Partnership has provided and we have not independently  verified. The net effect
of these  adjustment has been estimated by the  Partnership to be an increase in
1998 NiMo revenue of $8,054,041.


         DISPATCH ASSUMPTIONS

The  operation  of  Phases I and II under  the MRA  required  that the  dispatch
factors be adjusted to account for the changing  treatment of utility generation
in New York State as a result of the MRA. The  principal  impact on the dispatch
due to the MRA is that  many of the  units  competing  with  Phases I and II for
dispatch  would be  shutdown  or  restructured  as  merchant  plants.  A revised
dispatch  forecast was provided to us by the  Partnership  as prepared by Slater
Consulting  and dated March 19, 1998.  The revised  dispatch is a change to that
used in the Existing PPA Case and represents a dramatic increase in the dispatch
factors used for Phase I and  somewhat  less  dramatic  change for those used in
Phase II from those used in the Existing PPA Case. The dispatch factors for each
of Phase I and II under both the  existing PPA Case and the Amended PPA Case are
shown in Table 5.

         MAJOR MAINTENANCE

We have  accounted  for the  changes to the Major  Maintenance  expenditures  by
estimating  the Equivalent  Operating  Hours under the Amended PPA Case dispatch
assumptions  and have  calculated  a schedule of deposits at a level which would
keep the major  maintenance  reserve fund from dropping to a level below $0 and,
after inclusion of interest income,  will be adequate to continue to perform the
necessary  maintenance under the proposed  conditions.  The required deposit and
scheduled expenditures are shown in Table 6.

1.   Represents the Phase I and Phase II contract  capacity  tested output under
     the Niagara Mohawk PPA and the Con Edison PPA.

2.   Availability as estimated by Beck.

3.   Capacity  factors  based on annual  dispatch  factor as estimated by Slater
     Consulting adjusted for the assumed availability.  For the Amended PPA Case
     the capacity  factor for 1998 is a weighted  average  based on the dispatch
     factors for the Existing and Amended PPA Cases.

4.   Existing  PPA Energy  Sales is equal to the energy  sales to NiMo under the
     existing  PPA in MWh  calculated  as the  capacity  of  79,900 kW times the
     capacity  factor.  For the Amended PPA Case, in 1998 this is based on sales
     between January 1 and June 30, 1998.

5.   Delivered Energy Sales is equal to the energy sales to NiMo and potentially
     third  parties  under the Amended PPA in MWh  calculated as the capacity of
     79,900 kW times the capacity factor. For the Amended PPA Case, in 1998 this
     is based on sales between July 1 and December 31, 1998.

6.   Fixed Energy Sales is equal to the contract  year (July 1 - June 30) Annual
     Contract  Volume  in MWh  per  Attachment  I-A in the  Amended  PPA,  which
     quantity has been prorated on a calendar year basis.

7.   Delivered  Capacity  Sales is equal to the DMNC  less the  maximum  Monthly
     Contract Quantity of Capacity.

8.   Steam sales as  estimated by the  Partnership  based on 237,750 pph in 1998
     and assumed to increase at the rate of 3.1 percent per year,  minus  80,000
     pph supplied by GEP.


9.   Contract  fuel  purchased at the Facility for Phase I and Phase II based on
     net   purchases  of  21,357  MMBtu  per  day  and  55,935  MMBtu  per  day,
     respectively,  less a reduction in the Phase I Paramount  contract quantity
     of 6,000 MMBtu per day.


10.  Contract  fuel  purchased  for Phase I and Phase II based on  purchases  of
     23,391  MMBtu  per day and  60,308  MMBtu  per  day,  respectively,  less a
     reduction  in the Phase I  Paramount  contract  quantity  for the  capacity
     release of 6,000 MMBtu per day.

11.  No auxiliary fuel  consumption has been projected by the Partnership  since
     the dispatch factors  projected by Slater are sufficiently high to forecast
     that at least one unit will be on line at all times.


12.  Fuel  consumption at the Facility is based on varying levels of dispatch of
     Phase I and Phase II and upon the level of steam sales and Phase I start-up
     fuel as estimated by the Partnership.


13.  Fuel for Resale is equal to (1) Phase I net fuel  purchases at the Facility
     of  21,357  MMBtu  per day  less the  reduction  in the  Phase I  Paramount
     contract  quantity of 6,000 MMBtu per day,  less the fuel consumed by Phase
     I, plus;  (2) Phase II net fuel  purchases  at the Facility of 55,935 MMBtu
     per day less the fuel consumed by Phase II.

14.  Fuel  for  supplemental  firing  is  included  in  Fuel  Consumption.   The
     Partnership  estimates that enough  contract fuel will be available to meet
     supplemental  firing fuel  requirements  and that no spot market  purchases
     will be necessary.


15.  The fixed  component  from the  Existing  Niagara  Mohawk  PPA  includes  a
     contractual  capacity payment of $12.54 per kW-month  through 2002,  $13.19
     per kW-month through 2007, and $13.29 per kW-month through the remainder of
     the term of the Existing  Niagara  Mohawk PPA, all less a discount of $2.05
     per kW-month for those hours Phase I is  dispatched  on line;  plus a fixed
     transportation charge of $6.4157 per kW-month in January 1990 escalating at
     one-half  the rate of change in the  CPI-NJ,  assumed to be 3.1 percent per
     year for the period  beyond which actual  indices  were  available,  plus a
     fixed O&M payment of $3.1158 per kW-month in January 1990 escalating at the
     rate of change in the CPI-NJ.  For the Amended  PPA Case the  Existing  PPA
     Fixed Component is based on an annual weighted  average dispatch factor for
     the Existing and Amended PPA Case.

                      and the Amended PPA Case (continued)

16.  The  variable  component  Existing  Niagara  Mohawk PPA  includes an energy
     payment of $1.4286 per MMBtu on April 1, 1988 escalated each April 1 by the
     rate of change in Niagara Mohawk's  weighted average cost of No. 6 fuel oil
     and  natural  gas,  which is assumed to escalate at the rate of 3.1 percent
     per year for the period beyond which actual indices were available;  plus a
     variable  transportation  charge equal to $6.6732 per MWh in December  1993
     escalated  monthly at  one-half  the rate of change in the  CPI-NJ,  plus a
     variable O&M payment of $4.013 per MWh on March 1, 1989  escalating  at the
     rate of change in the CPI-NJ.  For the Amended  PPA Case the  Existing  PPA
     Variable  Component is based on an annual weighted  average dispatch factor
     for the Existing and Amended PPA Cases.

17.  The  Amended PPA  Delivered  Energy  payment is equal to the Market  Energy
     Price which is based upon an economic  dispatch analysis prepared by Slater
     Consulting.

     Contract  Capacity  Payment,  plus; (2) the Energy  Payment,  plus; (3) the
     Transportation  Payment,  plus; (4) the Operation and Maintenance  Payment;
     (5) less the Market Energy Price which has been deducted. Each component is
     adjusted  by  the  DMNC  Adjustment.   The  Contract  Capacity  Payment  is
     stipulated for the term of the Agreement and is equal to $73.83 per MWh and
     $73.60  per MWh for the first 2  contract  years.  The  Energy  Payment  is
     stipulated by the Agreement to be $15.80 per MWh and $15.95 per MWh for the
     first 2  contract  years,  or until  the  Independent  System  Operator  is
     established.  The Transportation  Payment is stipulated by the Agreement to
     be $7.15 per MWh and $7.35 per MWh for the first 2 contract years, or until

     Maintenance  Payment is stipulated by the Agreement to be $6.70 per MWh and
     $6.89  per MWh for the first 2  contract  years,  or until the  Independent
     System  Operator is  established.  The DMNC adjustment is a factor which is
     equal to the current DMNC divided by 79.9 MW. The Transportation  Price and
     the O&M Price are  adjusted by the  Inflation  Escalation  Factor  which is
     equal to the latest CPI - All Urban  Consumers  for New York - Northern New
     Jersey-Long  Island,  all Items  divided  by the CPI for July 1998 which is
     173.0.  The  Market  Energy  Price is equal to $26.30  per MWh in the first
     contract year as estimated by Slater.


19.  The Amended PPA  Delivered  Capacity  payment is equal to the Slater market
     price for capacity  which is estimated to be $2.40 per kW-month in 1997 and
     is  escalated  at the assumed  rate of change in the CPI of 3.1 percent per
     year.


20.  The  fixed  component  from the Con  Edison  PPA is equal to  $10.0476  per
     kW-month  in June 1992  escalated  monthly be a factor of  1.00407,  plus a
     fixed O&M component of $1.90 per kW-month  escalated  from March 1, 1989 at
     the rate of change in the  CPI-NJ,  plus a fixed  transportation  charge of
     $37.1083  per  MMBtu on March 1, 1989  escalated  at  one-half  the rate of
     change in the CPI-NJ based on: (1) the  contractual  base daily quantity of
     gas of 48,250 MMBtu, (corresponding to a DMNC of 252.3 MW) adjusted for the
     actual  DMNC of 265 MW, up to a maximum  DMNC of 265 MW; and (2) the annual
     availability.

21.  The variable  component Con Edison PPA includes a fuel payment of $1.49 per
     MMBtu on April 1, 1988  escalated  at the rate of  change  of the  NY-RWAP,
     which is assumed to  escalate  at the rate of 3.1  percent per year for the
     period beyond which the actual indices were available;  plus a variable O&M
     payment of $2.00 per MWh on March 1, 1989 escalated  monthly at the rate of
     change in the CPI-NJ;  plus a savings  component equal to 50 percent of the
     difference  between the aggregate fuel supply and  transportation  costs of
     Selkirk Phase II and the aggregate ceiling price under the Con Edison PPA.

22.  Steam  price is equal to GEP's  avoided  cost of  producing  steam which is
     calculated  as the sum of an  overhead  component  of $0.179  per Mlb and a
     variable  component of $0.89 per Mlb, both in March 1989,  and escalated at
     the rate of change in the CPI-NJ;  plus a fuel  component of $3.218 per Mlb
     in March 1989 escalated at the rate of change in Niagara Mohawk's  weighted
     average  cost of  fossil  fuel  assumed  to be 3.1  percent  per  year,  as
     estimated by the Partnership and reviewed by the Gas Consultant.

23.  Natural gas contract price  represents the weighted  average of Phase I and
     Phase II  contract  prices  calculated  by Beck based on  contract  pricing
     estimated by the Partnership and reviewed by the Gas Consultant.

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   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

               24 Power Park Drive, Selkirk, New York 12158-2299
                Telephone (518) 475-5773 Telefax (518) 475-5199



                                                                              SC


     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.

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