              WHEREAS,  the  Stockholder  owns all of the issued and outstanding
shares of capital stock  (collectively,  the "SHARES") of CH Resources,  Inc., a
New York corporation (the "COMPANY"); and

              WHEREAS,  the Stockholder desires to sell and the Buyer desires to
purchase,  all of the  Shares at the  price  and upon the  terms and  conditions
hereinafter set forth.

              NOW,  THEREFORE,  in  consideration  of the  foregoing  and of the
mutual covenants and agreements hereinafter set forth, the parties hereto hereby
agree as follows:

1.     DEFINITIONS

<PAGE>

       2.03   PURCHASE PRICE ADJUSTMENT

              (a)    The Purchase  Price will be adjusted  following  Closing to
compensate  for (i) any excess or deficiency as of the Closing Date with respect
to (A) the amount  reflected on the  September 30, 2001  unaudited  consolidated
balance  sheet of the Company for current  assets (less the amount of $1,664,400
attributable to the current  portion of the  Transmission  Congestion  Contracts
("TCCS") as of  September  30, 2001) less  current  liabilities  (except for the

              (c)    The  values  or  amounts  for each  item  reflected  on the
Adjustment  Statement  shall be binding  upon the Buyer,  unless the Buyer gives
written notice within thirty (30) days after receipt  thereof,  of  disagreement
with any of the values or amounts shown on the Adjustment Statement,  specifying

agreed  between  Stockholder  and Buyer.  If the Buyer and the  Stockholder  are
unable to resolve any such  disagreement  within thirty (30) days after the date

disputed  issues as the  Accountants may request and are available to that party
(or its independent public  accountants) and will be afforded the opportunity to
present to the Accountants  any material  relating to the  determination  and to
discuss the  determination  with the Accountants;  (ii) the determination by the
Accountants,  as  set  forth  in a  notice  delivered  to  both  parties  by the
Accountants,  will be binding and conclusive on the parties; and (iii) the Buyer

be  deleted  from the  Adjustment  Statement  and the  correct  amount  shall be
inserted in lieu thereof.

              (d)    Immediately  upon the  expiration  of the  thirty  (30) day
period for giving  the  Dispute  Notice,  if a Dispute  Notice is not given,  or
within five (5)  business  days after the  determination  has been  completed in
accordance  with this Section 2.03, (i) the Buyer shall pay to  Stockholder  the

gain, and the  Stockholder  shall  indemnify  Buyer and the Company  against any
Losses arising out of any failure to pay the Taxes attributable to the Company.

       12.02  ALLOCATION OF PURCHASE PRICE

              Buyer,  the Company and the  Stockholder  agree that the  Purchase
Price and the  liabilities  of the Company (plus other  relevant  items) will be
allocated  to the Assets of the  Company  for all  purposes  (including  Tax and
financial  accounting) in accordance with their fair market values as reasonably
determined by Buyer in accordance  with the  applicable  rules of Section 338 of
the Code and the  regulations  thereunder  and  consented to by the  Stockholder
(which consent shall not be unreasonably  withheld),  which  allocation shall be
binding upon the

                                     - 38 -
<PAGE>

parties.   Within  ninety  (90)  days  following  the  Closing,  Buyer  and  the
Stockholder shall agree on a list of assets to which the "Aggregate Deemed Sales
Price" (as defined under applicable  Treasury  Regulations) of the assets of the
Company shall be allocated.  All allocations contained in such schedule shall be
used by each party in  preparing  the  Section  338 Forms and all  relevant  Tax
Returns (including amended returns and claims for refund), subject to adjustment
to reflect (a) Stockholder's  selling expenses as a reduction of sales proceeds,
and (b) Buyer's  acquisition  expenses as an addition to the Purchase  Price. In
the event that the parties  cannot  agree on mutually  satisfactory  allocations
within said time period, the Independent Accounting Firm shall, at Stockholder's
and Buyer's joint and equal expense, determine the appropriate allocations based
solely on presentations of Buyer and Stockholder (and not by independent review)
within sixty (60) days of its  engagement.  The  allocations  determined  by the
Independent  Accounting Firm shall be binding on the parties.  The parties shall
take no action  inconsistent  with, or fail to take any action necessary for the
validity of the  Section  338(h)(10)  Election,  and shall adopt and utilize the
asset values  determined in making such  allocations  for the purpose of all Tax
Returns filed by them, and shall not  voluntarily  take any action  inconsistent
therewith  upon  examination  of any Tax  Return,  in any refund  claim,  in any
litigation or otherwise with respect to such Tax Returns.  Buyer and Stockholder
shall notify and provide the other with reasonable assistance in the event of an
examination, audit or other proceeding regarding the agreed upon allocations.

       12.03  TAX RETURNS AND PAYMENTS

              The Stockholder shall prepare or cause to be prepared and/or cause
to be filed all Tax  Returns for the  Company  and each  Subsidiary  for all Tax
periods ending on or prior to the Closing Date ("PRE-CLOSING PERIODS") which are
due after the Closing Date,  including  (without  limitation) the Tax Returns on
which the deemed assets sales resulting from the Section 338(h)(10) Election are
reported.  Such  returns  shall  be  prepared  in a manner  consistent  with the
Company's prior practice. The income or loss shall be reported on the Tax Return
to be filed for the  Company  and the  Subsidiaries  for the period  that begins
January  1,  2002  and  ends  on the  Closing  Date,  consistent  with  Treasury
Regulation Section 1.1502-76(b).  At least fifteen (15) days prior to the filing
of each such return,  the Stockholder  shall provide the return to the Buyer for
its review and comment and the  Stockholder  shall make such  revisions  to such
return  as  are  reasonably  requested  by  the  Buyer.   Stockholder  shall  be
responsible for payment of any Taxes for any Pre-Closing  Periods,  and shall be
entitled to any refunds or credits  shown on such  returns  necessary to conform
the Tax Return with the preceding  sentence or to be consistent  with applicable
Law and shall provide the Tax Return, as revised,  to the Buyer for filing.  The
Buyer shall  prepare or cause to be prepared  and the Buyer shall timely file or
cause to be filed any Tax Returns of the  Company  for Tax  periods  which begin
before the Closing Date and end after the Closing Date (the "STRADDLE PERIODS").
Such Tax Returns  shall be prepared in a manner  consistent  with the  Company's
prior practice to the extent  consistent with applicable  Laws. At least fifteen
(15) days prior to the filing of each such Tax Return  with  respect to Straddle
Periods,  the Buyer shall provide  copies of such Tax Return to the  Stockholder
for the Stockholder's review and comment and the Buyer shall make such revisions
to such Tax Returns as are reasonably requested by the Stockholder.  For returns
relating to the Straddle Periods,  the Stockholder shall pay to the Buyer within
fifteen  (15) days  after the date on which  Taxes are paid the  portion of such
Taxes which relates to the portion of such Taxable  period ending on the

                                     - 39 -
<PAGE>

Closing  Date in excess of any reserve for such Tax  liability  (rather than any
reserve for deferred Taxes  established to reflect  timing  differences  between
book and Tax income)  shown on the  balance  sheet in the  Financial  Statements
(such excess  "STRADDLE  PERIOD  TAXES").  Such  Straddle  Period Taxes shall be
calculated as though the taxable year of the Company  terminated as of the close
of business on the Closing Date;  PROVIDED,  HOWEVER,  that in the case of a Tax
not based on income, receipts, proceeds, profits or similar items, such Straddle
Period  Taxes  shall  be  equal  to the  amount  of Tax for the  taxable  period
multiplied  by a fraction,  the  numerator  of which shall be the number of days
from the  beginning  of the taxable  period  through  the  Closing  Date and the
denominator  of which shall be the number of days in the taxable  period.  After
the  Closing,  Buyer  shall not amend any Tax Returns  filed  before the Closing
without Stockholder's consent.

       12.04  COOPERATION ON TAX MATTERS

              (a)    The Buyer and the  Stockholder  shall  cooperate fully with
each other and with each party's  accounting firms and legal counsel,  as and to
the extent  reasonably  requested by the other  party,  in  connection  with the
filing of Tax Returns  pursuant to this SECTION 12 and any audit,  litigation or
other  proceeding  with  respect  to Taxes  or  pertaining  to the  transactions
contemplated by this Agreement. Such cooperation shall include the retention and
(upon the other party's request) the provision of records and information  which
are  reasonably  relevant  to  any  such  filing,  audit,  litigation  or  other
proceeding  and making  employees  available on a mutually  convenient  basis to
provide  additional   information  and  explanation  of  any  material  provided
hereunder.  The  Stockholder  agrees  (i) to retain all books and  records  with
respect to Tax matters  pertinent  to each of the  Company  and each  Subsidiary
relating  to any taxable  period  beginning  before the  Closing  Date until the
expiration of the statute of  limitations  (and,  to the extent  notified by the
Buyer or the  Stockholder,  any extensions  thereof) of the  respective  taxable
periods,  and to abide by all record retention  agreements entered into with any
taxing  authority,  and (ii) to give the other party  reasonable  written notice
prior to transferring,  destroying or discarding any such books and records and,
if the other party so requests  the  Stockholder  shall allow the other party to
take possession of such books and records prior to such transfer, destruction or
discarding.

              (b)    The Buyer and the Stockholder  further agree, upon request,
to use their reasonable best efforts to obtain any certificate or other document
from any  Governmental  Authority  or any other  person as may be  necessary  to
mitigate, reduce or eliminate any Tax that could be imposed (including,  but not
limited to, with respect to the transactions contemplated hereby).

       12.05  CERTAIN TAXES

              Except as otherwise agreed, all transfer, documentary, sales, use,
stamp,  registration  and other such Taxes and fees (including any penalties and
interest)  incurred in connection with this Purchase Agreement  (including,  but
not  limited  to any real  estate  transfer  tax,  sales  and use tax,  mortgage
recording  tax,  and any other city  transfer  tax or any similar tax imposed in
other states or  subdivisions),  shall be paid by the Buyer when due. Subject to
the preceding  sentence,  the party  required by  applicable  law shall file all
necessary Tax Returns and

                                     - 40 -
<PAGE>

other documentation with respect to all such transfer,  documentary, sales, use,
stamp,  registration  and other Taxes and fees,  and, if required by  applicable
Laws, the other party or its  Affiliates  will join in the execution of any such
Tax Returns and other documentation.

       12.06  TAX SHARING AGREEMENTS

              The  obligations and liabilities of the Company and any Subsidiary
to the  Stockholder  and  its  other  Tax  Affiliates,  and the  obligations  of
Stockholder  and all its other Tax Affiliates to the Company and any Subsidiary,
under the Central Hudson Group Federal Income Tax Allocation  Agreement shall be
terminated as of the Closing Date.

       12.07  CONTESTS

              (a)    Stockholder  and the Buyer shall  notify the other party in
writing  within thirty (30) days of receipt of written  notice of any pending or
threatened tax examination, audit or other administrative or judicial proceeding
(a  "TAX  CONTEST")   that  could   reasonably  be  expected  to  result  in  an
indemnification  obligation of such other party pursuant to this  Agreement.  If
the  recipient  of such notice of a Tax Contest  fails to provide such notice to
the other  party,  it shall not be  entitled  to  indemnification  for any Taxes
arising in  connection  with such Tax Contest,  but only to the extent,  if any,
that such  failure  or delay  shall have  adversely  affected  the  indemnifying
party's  ability to defend  against,  settle,  or satisfy  any  action,  suit or
proceeding  against  it, or any  damage,  loss,  claim or  demand  for which the
indemnified party is entitled to indemnification hereunder.

              (b)    If a Tax  Contest  relates  to  any  Taxes  for  which  the
Stockholder is liable in full hereunder,  the Stockholder shall, at its expense,
control the  defense and  settlement  of such Tax  Contest.  If such Tax Contest
relates to any Taxes for which Buyer is liable in full  hereunder,  Buyer shall,
at its own expense,  control the defense and settlement of such Tax Contest. The
party not in control of the defense  shall have the right to observe the conduct
of any Tax Contest at its expense,  including  through its own counsel and other
professional  experts.  Buyer and the  Stockholder  shall jointly  represent the
Company or any  Subsidiary  in any Tax Contest  relating to Taxes for which both
are liable hereunder, and fees and expenses related to such representation shall
be paid by the Buyer  and the  Stockholder  in  proportion  to their  respective
liabilities.

              (c)    Notwithstanding   anything  to  the   contrary  in  Section
12.06(b),  to the extent that an issue raised in any Tax Contest  controlled  by
one party or jointly  controlled could materially affect the liability for Taxes
of the other party,  the  controlling  party shall not, and neither party in the
case of joint control shall,  enter into a final settlement  without the consent
of the other party,  which consent shall not be unreasonably  withheld.  Where a
party withholds its consent to any final settlement,  that party may continue to
initiate further proceedings, at its own expense, and the liability of the party
that wished to settle (as between the consenting and non-consenting party) shall
not  exceed the  liability  that would have  resulted  from the  proposed  final
settlement including interest, additions to Tax, and penalties that have accrued
at that time, and the non-consenting  party shall indemnify the consenting party
for such Taxes.

                                     - 41 -
<PAGE>

              (d)    Notwithstanding  any other  provision of this  Agreement to
the  contrary,  if a Tax  Contest  results in an increase in Taxes for which the
Stockholder  is  liable   hereunder,   and  such  increase  is  attributable  to
adjustments  based on timing  differences  which will reverse in taxable periods
ending  subsequent to the Closing Date, and, Buyer shall pay to the Stockholder,
upon the  Stockholder's  request,  an amount  equal to the present  value of the
reduction in Taxes  payable by the Buyer and its  Affiliates  in future  taxable
periods by reason of such  reversal,  determined by using a discount rate of 12%
and an assumed tax rate of 40%,  and by assuming  that such  reduction  in Taxes
will occur in the year or years of reversal.

       12.08  DISPUTES

              In the event that a dispute arises between the Stockholder and the
Buyer as to the  amount of  Taxes,  or  indemnification  with  respect  to Taxes
(whether or not attributable to the Company),  the parties shall attempt in good
faith to resolve such  dispute,  and any agreed upon amount shall be paid to the
appropriate  party. If such dispute is not resolved thirty (30) days thereafter,
the parties  shall  submit the dispute to the  Independent  Accounting  Firm for
resolution,  which  resolution  shall be final,  conclusive  and  binding on the
parties.  Notwithstanding  anything in this Agreement to the contrary,  the fees
and expenses of the  Independent  Accounting Firm in resolving the dispute shall
be borne in proportion to the determination of the Independent  Accounting Firm.
Any payment  required to be made as a result of the resolution of the dispute by
the  Independent  Accounting  Firm shall be made within ten (10) days after such
resolution (together with any interest determined by the Independent  Accounting
Firm to be appropriate).

contained in this Purchase  Agreement has been the cause of, or resulted in, the
failure of the Closing to occur by such date;

breach,  failure or misrepresentation is not cured within thirty (30) days after
notice thereof;

                                     - 42 -
<PAGE>

              (d)    by the  Stockholder  if the Buyer shall have  breached,  or

hereunder;  PROVIDED,  HOWEVER,  that  the  obligations  of  the  parties  as to
confidentiality  provided in SECTION 3.02 and the  provisions  of SECTION  14.03
relating to the payment of expenses, shall not be extinguished but shall survive
such  termination,  and nothing herein shall relieve any party for any breach of
this  Agreement.  The parties  hereto shall have any and all remedies to enforce
such obligations  provided at law or in equity (including,  without  limitation,
specific performance).

14.    MISCELLANEOUS

       14.01  ADDITIONAL ACTIONS AND DOCUMENTS

              Each of the parties  hereto  hereby  agrees to take or cause to be

otherwise,  without the prior written consent of the other parties  hereto,  and
any such  assignment  contrary to the terms hereof shall be null and void and of
no force  and  effect.  In no event  shall  the  assignment  by any party of its

                                FORM OF GUARANTY

              THIS GUARANTY (this "Guaranty") is made as of ________, 2002 by CH
Energy Group, Inc., a New York corporation ("Guarantor"),  in favor of WPS Power
Development, Inc., a Wisconsin corporation ("Buyer").

                                    RECITALS

              Concurrently  herewith  (such date the  "Closing  Date"),  Central
Hudson Energy Services, Inc., a New York corporation and wholly-owned subsidiary
of Guarantor ("Seller"), is consummating the sale to Buyer of all of the capital
stock of CH Resources,  Inc., a New York corporation and wholly-owned subsidiary
of Seller ("Company"),  pursuant to that certain Stock Purchase Agreement, dated
as of December __, 2001 (the  "Purchase  Agreement"),  between  Seller and Buyer
(any capitalized  terms used herein and not defined herein having the respective
meanings assigned in the Purchase Agreement).

              To  induce  Buyer  to  enter  into  the  Purchase   Agreement  and
consummate  the  transactions  contemplated  thereby,  Guarantor  has  agreed to
execute and deliver this Guaranty.

              The execution and  performance by Buyer of the Purchase  Agreement
and the transactions  contemplated thereby will benefit Guarantor.  Without this
Guaranty,  Buyer  would not  execute  and  deliver  the  Purchase  Agreement  or
consummate the transactions contemplated thereby. Therefore, in consideration of
the execution and delivery by Buyer of the Purchase  Agreement and  consummation
of the transactions  contemplated  thereby,  Guarantor has agreed to execute and
deliver this Guaranty.

              NOW,  THEREFORE,  in consideration of the premises,  and for other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, Guarantor agrees as follows:

1.            GUARANTY.   Guarantor   guarantees  to  Buyer  and  its  permitted
successors and assigns the full and prompt payment and  performance  when due of
all of the obligations of Seller under the Purchase Agreement (such obligations,
the "Guaranteed Obligations").

2.            UNCONDITIONAL OBLIGATIONS.  This Guaranty is a guaranty of payment
and  performance  and not of collection  and is an absolute,  unconditional  and
irrevocable guarantee of the full and prompt payment and performance when due of
all of the Guaranteed  Obligations,  whether or not from time to time reduced or
extinguished or hereafter increased or incurred, and whether or not recovery may
be, or hereafter may become,  barred by any statute of limitations or otherwise.
If any payment made by Seller or any other Person and applied to the  Guaranteed
Obligations is at any time annulled, set aside, rescinded, invalidated, declared
to be fraudulent or preferential or otherwise  required to be repaid or refunded
for any reason, including bankruptcy,  insolvency,  or reorganization,  then, to
the  extent of such  payment or  repayment,  the  liability  of

<PAGE>

Guarantor  will  continue to be in full force and effect (or be  reinstated,  if
applicable) as fully as if such payment had never been made. Guarantor covenants
that this Guaranty will not be fulfilled or  discharged,  except by the complete
payment and  performance of the Guaranteed  Obligations,  whether by the primary
obligor or Guarantor under this Guaranty. Without limiting the generality of the
foregoing, Guarantor's obligations hereunder will not be released, discharged or
otherwise affected by the following:

              (a)    any change in the Purchase  Agreement or the obligations of
Seller thereunder, or any insolvency, bankruptcy or similar proceeding affecting
Seller  or its  assets  or any  defense  that  may  arise  in  such  insolvency,
bankruptcy or similar proceeding;

              (b)    the  existence  of any claim or set-off  that seller has or
that Guarantor may have against Buyer,  whether in connection with this Guaranty
or any  unrelated  transaction,  provided  that nothing in this Guaranty will be
deemed a waiver by Guarantor of any claim or prevent the  assertion of any claim
by separate suit;

              (c)    any law now or  hereinafter  in effect in any  jurisdiction
affecting any of the terms of the Purchase Agreement or the rights of Buyer with
respect thereto;

              (d)    any  change  in  the  corporate  existence,   structure  or
ownership of Guarantor  or Seller or any  assignment  by Seller of its rights or
obligations under the Purchase Agreement;

              (e)    the existence of any default,  breach,  or  dissolution  in
connection with the Purchase Agreement;

              (f)    the  existence  of any release or amendment or waiver of or
consent to departure  from any other  guaranty for all or any of the  Guaranteed
Obligations;

              (g)    any  exchange  of,  release  of or  non-perfection  of  any
interest in any collateral,  or any release or amendment or waiver of or consent
to departure from any guaranty, for all or any of the obligations of Seller; and

              (h)    any other act,  omission  to act,  delay of any kind by any
party hereto or any other Person, or any circumstance whatsoever that might, but
for the provisions of this Section, constitute a legal or equitable discharge of
the obligations of Guarantor hereunder.

              This Guaranty will in all respects be a continuing,  absolute, and
unconditional guaranty irrespective of the genuineness,  validity, regularity or
enforceability  of  the  Guaranteed  Obligations  or  any  part  thereof  or any
instrument  or  agreement  evidencing  any of  the  Guaranteed  Obligations  ore
relating thereto, or the existence,  validity,  enforceability,  perfection,  or
extent of any  collateral  therefor or any other  circumstances  relating to the
Guaranteed  Obligations  which  might  otherwise  constitute  a  defense  to the
Guaranteed Obligations or this Guaranty.

3.            INDEPENDENT  OBLIGATIONS.  Guarantor  agrees  that the  Guaranteed
Obligations  are  independent  of the  obligations  of Seller under the Purchase
Agreement and if any default occurs hereunder,  a separate action or actions may
be brought  and  prosecuted  against  Guarantor  whether

                                     - 2 -
<PAGE>

or not Seller is joined therein. Buyer may maintain successive actions for other
defaults of Guarantor.  Buyer's  rights  hereunder  will not be exhausted by the
exercise of any of its rights or remedies or by any such action or by any number
of successive actions until and unless all Guaranteed Obligations have been paid
and fully performed.

              (a)    Guarantor  agrees that Buyer may enforce this Guaranty,  at
any  time and from  time to time,  without  the  necessity  of  resorting  to or
exhausting  any security or  collateral  and without the necessity of proceeding
against  Seller.  Guarantor  hereby waives the right to require Buyer to proceed
against Seller, to exercise any right or remedy under the Purchase Agreement, or
to pursue any other remedy or to enforce any other right.

              (b)    Guarantor  will  continue  to be subject  to this  Guaranty
notwithstanding:  (i) any modification,  agreement or stipulation  between Buyer
and Seller,  or their  respective  successors  and assigns,  with respect to the
Purchase Agreement or the Guaranteed Obligations;  (ii) any waiver of or failure
to enforce any of the terms,  covenants or conditions  contained in the Purchase
Agreement  or any  modification  thereof;  (iii) any  release of Seller from any
liability  with  respect  to the  Purchase  Agreement;  or (iv) any  release  or
subordination  of any  collateral  then  held  by  Buyer  as  security  for  the
performance by Seller of the Guaranteed Obligations.

              (c)    The   Guaranteed   Obligations   are  not   conditional  or
contingent upon the genuineness,  validity,  regularity or enforceability of the
Purchase  Agreement or the pursuit by Buyer of any  remedies  which Buyer either
now has or may hereafter have with respect thereto under the Purchase Agreement.

4.            LIABILITY OF GUARANTOR.

              (a)    Buyer may enforce this  Guaranty  upon the  occurrence of a
breach by  Seller  of any of the  Guaranteed  Obligations,  notwithstanding  the
existence of any dispute  between Seller and Buyer with respect to the existence
of any such breach.

              (b)    Guarantor's  performance  of  some,  but  not  all,  of the
Guaranteed  Obligations  will  in  no  way  limit,  affect,  modify  or  abridge
Guarantor's  liability  for  those  Guaranteed  Obligations  that  have not been
performed.

              (c)    Buyer,  upon such  terms as it deems  appropriate,  without
notice or demand and without  affecting the validity or  enforceability  of this
Guaranty or giving rise to any reduction,  limitation,  impairment, discharge or
termination of Guarantor's  liability hereunder,  from time to time may (i) with
respect to Seller's financial obligations,  renew, extend, accelerate,  increase
the rate of interest on, or otherwise change the time, place, manner or terms of
payment of financial obligations that are Guaranteed Obligations, or subordinate
the payment of the same to the payment of any other  obligations,  or any or all
of the above, (ii) settle, compromise, release or discharge, or accept or refuse
any offer of performance with respect to, or  substitutions  for, the Guaranteed
Obligations or any agreement  relating  thereto,  (iii) request and accept other
guarantees  of the  Guaranteed  Obligations  and take and hold  security for the
payment of this Guaranty or the Guaranteed Obligations, (iv) release, surrender,
exchange, substitute,  compromise, settle, rescind, waive, alter, subordinate or
modify,  with or without  consideration,

                                     - 3 -
<PAGE>

any security for performance of the Guaranteed Obligations, any other guarantees
of the  Guaranteed  Obligations,  or any other  obligation  of any  Person  with
respect  to the  Guaranteed  Obligations,  (v)  enforce  and apply any  security
hereafter held by or for the benefit of Buyer in respect of this Guaranty or the
Guaranteed  Obligations  and  direct  the  order or manner  of sale  thereof  or
exercise  of any other  right or remedy  that  Buyer may have  against  any such
security, as Buyer in its discretion may determine,  and (vi) exercise any other
rights available to it under the Purchase Agreement.

              (d)    This Guaranty and the  obligations  of Guarantor  hereunder
will be  valid  and  enforceable  and  will  not be  subject  to any  reduction,
limitation,  impairment,  discharge or  termination  for any reason  (other than
indefeasible  performance  in full  of the  Guaranteed  Obligations),  including
without  limitation  the  occurrence  of any of the  following,  whether  or not
Guarantor  will have had notice or knowledge of any of them:  (i) any failure or
omission to assert or enforce or agreement or election not to assert or enforce,
or the stay or enjoining,  by order of court,  by operation of law or otherwise,
of the  exercise or  enforcement  of any claim or demand or any right,  power or
remedy  (whether  arising  under the  Purchase  Agreement,  at law, in equity or
otherwise)  with  respect to the  Guaranteed  Obligations  or any  agreement  or
instrument  relating  thereto;  (ii)  any  rescission,   waiver,   amendment  or
modification  of,  or any  consent  to  departure  from,  any of  the  terms  or
provisions  (including  without  limitation  provisions  relating  to  events of
default) of the Purchase  Agreement  or any  agreement  or  instrument  executed
pursuant  thereto;  (iii)  Buyer's  consent  to the  change,  reorganization  or
termination  of the  corporate  structure  or  existence  of  Seller;  (iv)  any
defenses,  set-offs or  counterclaims  Seller or Guarantor  may allege or assert
against  Buyer in  respect  of the  Guaranteed  Obligations,  including  but not
limited to failure of  consideration,  breach of warranty,  payment,  statute of
frauds,  statute of limitations,  accord and satisfaction and usury; and (v) any
other act or thing or omission, or delay to do any other act or thing, which may
or might in any manner or to any extent vary the risk of Guarantor as an obligor
in respect of the Guaranteed Obligations.

5.            WAIVERS.  To the fullest extent permitted by law, Guarantor hereby
waives and agrees not to assert or take  advantage  of: (a) any right to require
Buyer to proceed  against  Seller or any other  Person or to proceed  against or
exhaust any security  held by Buyer at any time or to pursue any right or remedy
under the  Purchase  Agreement  or any  other  remedy in  Buyer's  power  before
proceeding  against  Guarantor;  (b) any defense that may arise by reason of the
incapacity,  lack of authority,  death or disability of, or revocation hereby by
Guarantor  or  Seller or any other  Person  or the  failure  of Buyer to file or
enforce a claim against the estate (either in administration,  bankruptcy or any
other  proceeding) of any such Person;  (c) any defense that may arise by reason
of any presentment,  demand for payment or performance or otherwise,  protest or
notice of any other kind or lack thereof;  (d) any right or defense  arising out
of an election of remedies by Buyer; (e) all notices to Guarantor, to Seller, or
to any other Person, including, but not limited to, notices of the acceptance of
this Guaranty or the creation, renewal, extension,  modification, accrual of any
of  Seller's  obligations  under the  Purchase  Agreement,  or of default in the
payment or  performance  of any such  obligations,  enforcement  of any right or
remedy with respect thereto or notice of any other matters relating thereto; (f)
any statute of  limitations  affecting  Guarantor's  liability  hereunder or the
enforcement thereof; (g) any requirements of diligence or promptness on the part
of  Buyer;  (h)  any  defense  arising  out  of  the  lack  of  validity  or the
unenforceability  of the  Guaranteed  Obligations or any agreement or instrument
relating

                                     - 4 -

thereto or by reason of the cessation of the  liability of Seller,  or any other
Person  from  any  cause  other  than  indefeasible  performance  in full of the
Guaranteed  Obligations;  (i) any defense  based upon any statute or rule of law
which  provides that the obligation of a surety must be neither larger in amount
nor in other  respects  more  burdensome  than  that of the  principal;  (j) any

results  in or aids the  discharge  or  release  of Seller or  Guarantor  or any
security given or held by Buyer in connection  with the Guaranteed  Obligations;
and (k) any and all surety ship defenses under applicable law.

6.            CUMULATIVE  RIGHTS.  All  rights  powers  and  remedies  of  Buyer

circumstances  bearing  upon the risk of non  payment or  nonperformance  of the
Guaranteed Obligations. Guarantor hereby waives and relinquishes any duty on the
part of Buyer to disclose any matter,  fact or thing  relating to the  business,

Guaranty are governed by and will be  construed in  accordance  with the laws of
the State of New York  applicable to contracts made and performed in such State,

Guarantor with respect to the transactions  contemplated  hereby, and supersedes

14.           CONSTRUCTION  OF AGREEMENT.  Ambiguities or  uncertainties  in the
wording of this  Guaranty  will not be construed  for or against any party,  but
will be  construed  in the manner that most  accurately  reflects  the  parties'
intent as of the date hereof.

15.           NO WAIVER.  Any forbearance or failure to exercise,  and any delay
by Buyer in exercising, any right, power or remedy hereunder will not impair any
such right, power or remedy or be construed to be a waiver thereof,  nor will it
preclude the further exercise of any such right,  power or remedy.  The remedies
herein  provided are  cumulative  and not exclusive of any remedies  provided by
law, by agreement or otherwise.

16.           BANKRUPTCY; POST-PETITION INTEREST.

              (a)    The  obligations of Guarantor  under this Guaranty will not
be reduced, limited, impaired, discharged,  deferred, suspended or terminated by
any proceeding, voluntary or involuntary,  involving the bankruptcy, insolvency,
receivership,  reorganization,  liquidation  or  arrangement of Seller or by any
defense which Seller may have by reason of the order,  decree or decision of any
court or  administrative  body resulting from any such proceeding.  Buyer is not
obligated to file any claim  relating to the  Guaranteed  Obligations  if Seller
becomes subject to a bankruptcy,  reorganization, or similar proceeding, and the
failure of Buyer so to file will not affect  Guarantor's  obligations under this
Guaranty.

              (b)    Guarantor  acknowledges and agrees that any interest on any
portion of the Guaranteed  Obligations  which accrues after the  commencement of
any  proceeding  referred to in clause (a) above (or, if interest on any portion
of the Guaranteed  Obligations ceases to accrue by

operation of law by reason of the commencement of said proceeding, such interest
as would have  accrued on such  portion of the  Guaranteed  Obligations  if said
proceedings  had  not  been  commenced)  will  be  included  in  the  Guaranteed
Obligations  because  it is the  intention  of  Guarantor  and  Buyer  that  the
Guaranteed Obligations should be determined without regard to any rule of law or
order that may  relieve  Seller of any portion of such  Guaranteed  Obligations.
Guarantor will permit any trustee in bankruptcy, receiver, debtor-in-possession,
assignee  for the benefit of creditors  or any similar  Person to pay Buyer,  or
allow the claim of Buyer in respect of any such interest accruing after the date
on which such proceeding is commenced.

              IN WITNESS WHEREOF, Guarantor has executed this Guaranty as of the
date first written above.

Ladies & Gentlemen:

We refer you to the two Transmission Congestion Contracts held by Central Hudson
Enterprises   Corporation  ("CHEC")  described  in  the  Confidential   Offering
Memorandum regarding CH Resources, Inc. dated September 2001 (the "TCCs").

This letter reflects our understanding and agreement  regarding the transfer and
assignment of the TCCs. CHEC shall transfer and assign all of its rights,  title
and  interest  in and to the TCCs to WPS  Energy  Services,  Inc.  or one of its
corporate  affiliates  ("ESI"),  and ESI shall assume all obligations  under the
TCCs, for a cash purchase price of $3,982,440  payable by ESI to CHEC at closing
subject to adjustment as provided below. Such transfer shall take place pursuant
to an Assignment and Assumption  Agreement  containing  reasonable and customary
terms and  conditions  to be agreed  between  the  parties.  The closing of such
transfer  shall take place no later than the  closing  under the Stock  Purchase
Agreement  dated as of  December  21, 2001 (the "SPA")  between  Central  Hudson
Energy Services, Inc. and us.

The purchase  price shall be adjusted as follows:  (i) if the closing is delayed
beyond May 15, 2002,  the price shall be reduced by $4,700 for each day from and
including May 16, 2002 through and including the date of the closing  subject to
the  limitation  set forth in Section  9.14 of the SPA;  and (ii) if the closing
occurs prior to April 16, 2002,  the price shall be increased by $4,700 for each
day after the closing  date to but not  including  April 16,  2002.  In no event
shall such adjustment exceed an aggregate amount of $625,000.

If this  letter  meets  with  your  understanding  of our  agreement,  please so
indicate by signing in the space  provided  below,  whereupon this will become a
binding agreement between us.

Very truly yours,
