Exhibit (10) (i) 63

This PARTICIPATION AGREEMENT, dated as of June 1, 1977, between the New York
         State Energy Research and Development Authority, a body corporate and
         politic, constituting a public benefit corporation, established and
         existing under and by virtue of the laws of the State of New York (the
         "Authority") and Central Hudson Gas & Electric Corporation, a
         corporation duly organized and existing and qualified to do business as
         a public utility under the laws of the State of New York (the
         "Corporation"),

                              W I T N E S S E T H:

         WHEREAS, pursuant to special act of the Legislature of the State of New
York (Title 9 of Article 8 of the Public Authorities Law of New York, as from
time to time amended and supplemented, herein called the "Act"), the Authority
has been established, as a body corporate and politic, constituting a public
benefit corporation; and

         WHEREAS, pursuant to the Act, the Authority is empowered to contract
with any power company to participate in the incorporation of features in power
plants and the construction of associated facilities to the extent required by
the public interest in development, health, recreation, safety, conservation of
natural resources and aesthetics; and

         WHEREAS, the Authority is also authorized under the Act to borrow money
and issue its negotiable bonds and notes to provide sufficient moneys for
achieving its corporate purposes; and

         WHEREAS, the Authority is also authorized under the Act to enter into
any contracts and to execute all instruments necessary or convenient for the
exercise of its corporate powers and the fulfillment of its corporate purposes;
and

         WHEREAS, the Corporation is a public utility corporation doing business
in the State of New York and operates power plants in the State of New York; and

         WHEREAS, the Legislature of the State of New York has determined that,
because interest costs incurred by public utilities are reflected in the rates
paid by the customers of such utilities and because governmental action has
mandated the installation of pollution control facilities, it is in the public
interest to enable utilities to obtain the lowest possible interest rate on
bonds sold to provide pollution control facilities; and

         WHEREAS, the Corporation has requested that the Authority participate
in financing the acquisition, construction and installation of pollution control
facilities, and other facilities required by the public interest in development,
health, recreation, safety, conservation of natural resources and aesthetics at
certain of its power plants and, as part of such participation, that the
Authority issue bonds pursuant to the Act to provide funds to finance

                                        2

such facilities in an aggregate principal amount not exceeding the cost of such
facilities and the expenses incurred in connection with the authorization,
issuance and sale of such bonds; and

         WHEREAS, the Authority proposes to issue its Pollution Control Revenue
Bonds (Central Hudson Gas & Electric Corporation Projects), in series from time
to time, for the purpose of defraying the cost of such facilities, all such
bonds to be issued under and secured by a Bond Resolution adopted by the
Authority on May 26, 1977 (the "Resolution"); and

         WHEREAS, the Authority proposes to issue an initial series of such
bonds in the principal amount of $4,500,000, designated Pollution Control
Revenue Bonds (Central Hudson Gas & Electric Corporation Projects), Series A, in
order to reimburse the Corporation for its costs for the construction of certain
pollution control and other facilities in certain power plants operated by the
Corporation;

                                   ARTICLE III

                   Construction of Projects; Issuance of Bonds

         SECTION 3.01. Construction of Projects. 1. The Corporation has
completed construction of Project A and will proceed with due diligence to
complete construction of any Additional Project with all reasonable dispatch and
in accordance with the plans and specifications therefor. Each Project shall
belong to and be the property of the Corporation. In order to effectuate the
purposes of this Participation Agreement, the Corporation, in its own name, will
do or cause to be done all things requisite or proper for the construction of
each Project and the fulfillment of the obligations of the Corporation under
this Participation Agreement.

         2. Notwithstanding any other provisions of this Participation Agreement
to the contrary, the Corporation shall not be required to complete the
construction of any component of a Project if the Corporation shall determine in
good faith that either:

         (a) the completion of such component is no longer necessary in order to
         achieve its intended purpose for any reason, including changes in law
         or regulations or technological developments or a change in the design
         or mode of operation of, or abandonment of operation of, the plant with
         which such component is associated; or

         (b) such component, if completed, will fail to achieve its intended
         purpose; or

         (c) the completion of construction of such component or the operation
         of such component would result in the incurrence of unreasonable
         expenses or liabilities by the Corporation which were not anticipated
         at the date of the execution and delivery
<PAGE>

                                        5

         of the Supplemental Participation Agreement relating to any Additional
         Project, and, in the opinion of an Authorized Corporation
         Representative (who shall be a licensed professional engineer), the
         plant with which such component is associated may be operated in
         compliance with applicable regulatory standards without the inclusion
         of such component.

         3. Whenever the Corporation shall make a determination referred to in
subsection 2 above, the Corporation shall deliver to the Trustee and the
Authority a certificate of an Authorized Corporation Representative setting
forth such determination. Not less than 30 days prior to the delivery of such
certificate the Corporation shall notify the Authority and the Trustee of its
intention to make such determination and shall describe in reasonable detail the
basis therefor.

         SECTION 3.02. Sale of Series A Bonds and deposit of proceeds;
Additional Bonds; Liability under Bonds. 1. In order to provide funds for
payment of the Cost of Construction of Project A, the Authority, as soon as
practicable after the execution of this Participation Agreement, and
concurrently with the issuance and delivery to the Trustee of the Series A First
Mortgage Bonds as provided in Section 4.01, will issue, sell and deliver the
Series A Bonds to the initial purchasers thereof, all pursuant to and as
provided in the Purchase Contract for the Series A Bonds between the Authority
and Kidder, Peabody & Co. Incorporated and White, Weld & C o. Incorporated, as
Representatives, and will deposit the proceeds of such sale of the Series A
bonds and a sum equal to the accrued interest, if any, paid by the initial
purchasers of the Series A Bonds with the Trustee, in the separate account with
respect to Project A in the Project Fund.

         2. So long as the Corporation shall not be in default hereunder and
whenever the Corporation so requests, the Authority may, but shall not be
obligated to, issue Additional Bonds in aggregate principal amounts specified
from time to time by the corporation (i) to finance the Cost of Construction of
any Additional Project, or (ii) to refund any Bonds, provided that the authority
shall comply with the requirements of Article III of the Resolution, the
Corporation shall comply with the requirements of Section 4.01 hereof and the
Authority and the Corporation shall enter into a Supplemental Participation
Agreement with respect to the issuance of such Additional Bonds. Each such
Supplemental Participation Agreement shall contain such provisions as the
Authority and the Corporation shall agree upon and, in the case of a
Supplemental Participation Agreement with respect to the issuance of Additional
bonds to finance the Cost of Construction of an Additional Project, shall
contain (in one or more exhibits) a description of such Additional Project.

         3. The Bonds shall not be general obligations of the Authority, and
shall not constitute an indebtedness of or a charge against the general credit
of the Authority or give rise to any pecuniary liability of the Authority. The
liability of the Authority under the Bonds shall be enforceable only to the
extent provided in the Resolution, and the Bonds shall be payable solely from
the First Mortgage Bond Payments and any other funds held by the Trustee under
the Resolution and available for such payment. The Bonds shall not be a debt of
the State of New York and the State of New York shall not be liable thereon.

         SECTION 3.03. Disbursements from Project Fund. 1. The Authority has, in
the Resolution, authorized and directed the Trustee to make payments from the
Project Fund, in accordance with Section 5.03 of the Resolution, to pay the Cost
of Construction of each Project upon receipt from time to time of requisitions
signed by an Authorized Corporation Representative, stating with respect to each
payment to be made for such Project:

         (a) the separate account in the Project Fund to which such requisition
relates;

         (b) the requisition number;

         (c) the component or components of such Project to which the
disbursement relates or has been allocated and the nature of the disbursement;

         (d) the payee, which may be the corporation in the case of
reimbursements for advances and payments made or costs incurred or work done by
the Corporation;

         (e) the amount of such payment;

         (f) that the disbursement will be used to pay, or reimburse the
Corporation for, a Cost of Construction of such Project and that it is a proper
charge against the separate account for such Project in the Project Fund;

         (g) that none of the items for which the disbursement is requested has
formed the basis for any disbursement theretofore made from the Project Fund;

         (h) that the disbursement will not be used in a manner that would
result in a violation of any covenant contained in Sections 3.10 or 5.04; and

         (i) that no event of default as defined in the Corporation Indenture
shall have occurred and be continuing and that no event which with the lapse of
time alone would become such a default has occurred and is continuing.

         The Corporation will cause such requisitions to be submitted to the
Trustee as may be necessary to effect payments out of the Project Fund in
accordance with the provisions of the Resolution.

         Concurrently with the delivery by the Corporation of each requisition
to the Trustee, the Corporation will deliver to the Authority a copy of such
requisition and any attachments thereto. The Authority and the Trustee may rely
as to the completeness and accuracy of all statements in such requisition and
the Corporation will indemnify and save harmless the Authority and the Trustee
from any liability incurred in connection with any requisition so delivered and
the payment of funds in reliance thereon.

         2. Except for amounts retained by the Trustee at the written direction
of an Authorized Corporation Representative for payment of items included in the
Cost of
<PAGE>

                                        7

Construction of any Project but not then due and payable or the liability for
payment of which is being contested or disputed by the Corporation, all moneys
attributable to any single issue of Bonds remaining in the separate account for
such Project in the Project Fund after the Completion Date with respect to such
Project shall, at the written direction of an Authorized Corporation
Representative, be paid (A) into the Bond Fund for application to (i) the
redemption of the issue of Bonds used to finance such Project pursuant to the
optional redemption, mandatory redemption or default provisions of the
Resolution, (ii) payment of interest on the issue of Bonds used to finance such
Project to the extent that the sum of (a) such interest payments and any prior
interest payments on such Bonds pursuant to this clause (ii) and (b) the amount
expended from the proceeds of any such single issue of Bonds on the Cost of
Construction of Other Project Facilities (other than issuance expenses of such
single issue of Bonds attributable thereto), is less than one-ninth of the
amount of the proceeds expended from any such single issue of Bonds on the Cost
of Construction of Pollution Control Facilities (other than issuance expenses of
such single issue of Bonds attributable thereto), or (iii) the purchase of the
issue of Bonds used to finance such Project, or any portion thereof, at a price
or prices not in excess of the then current or first applicable optional
redemption price (and, pending any such application under this clause (A), be
invested in securities provided that such investment will not be in violation of
the certifications and representations made to the Authority by the Corporation
in Section 3.11) or (B) into any other separate account (established by the
Authority pursuant to subsections 2 or 3 of Section 5.01 of the Resolution) in
the Project Fund for application solely to the Cost of Construction of any
Additional Project to be financed from such separate account. Any balance
remaining of such retained amounts to the extent not disbursed in accordance
with subsection 1 above, shall, at the written direction of an Authorized
Corporation Representative, be similarly applied.

         SECTION 3.04. Revision of plans and specifications. The Corporation may
revise the plans and specifications for a Project at any time and from time to
time; provided, however that no such revision shall be made prior to the
Completion Date with respect to such Project which would render the description
of such Project inaccurate, except in accordance with the following procedure:

         (a) Prior to any such revision the Corporation shall deliver to the
         Trustee and the Authority (1) a certificate of an Authorized
         Corporation Representative, setting forth the text of the change in the
         description of such Project which would be necessary to accurately
         reflect the proposed revision in plans and specifications, and
         certifying that, notwithstanding such revision, such Project will still
         be designed to serve the purposes which would have been served by such
         Project in the absence of such revision, and (2) an unqualified opinion
         of counsel, who shall be satisfactory to the Trustee, experienced in
         matters relating to tax exemption of interest on bonds issued by states
         and their political subdivisions, that such revisions of such Project
         description and the expenditure of moneys from the Project Fund under
         the provisions of the Resolution to pay the Cost of Construction of
         such Project in accordance with the revised description of such Project
         will not impair the
<PAGE>

                                        8

         exemption of interest on any of the Bonds then outstanding from Federal
         income taxation.

         (b) Ten days after the receipt by the Authority and the Trustee of the
         certificate and opinion referred to in paragraph (a) above, such
         Project description shall be deemed amended to include such revision
         for all purposes of this Participation Agreement and the Resolution.
         Upon the request of either party or the Trustee, the Authority and the
         Corporation shall enter into an appropriate instrument reflecting such
         amendment.

         SECTION 3.05. Certification of completion of Projects. When a Project
has been completed (except for components as to which the Corporation has
delivered to the Trustee and the Authority pursuant to subsection 3 of Section
3.01 a certificate of an Authorized Corporation Representative to the effect
that the Corporation has determined not to complete such components), the
Corporation shall promptly deliver to the Trustee and the Authority a
certificate of an Authorized Corporation Representative to the effect that, as
of a specified date, such Project has been completed (except as aforesaid). Such
certificate shall specify the components of such Project, if any, the completion
of which has been excused and the date or dates of the certificate or
certificates delivered pursuant to subsection 3 of Section 3.01 with respect to
such components. The certificate delivered pursuant to this Section 3.05 shall
also contain an appropriate direction to the Trustee with respect to any amount
in the separate account relating to such Project in the Project Fund which is to
be retained or thereupon disposed of as provided in subsection 2 of Section
3.03. The Trustee may rely as to the accuracy and completeness of all statements
in such certificate.

         Notwithstanding the foregoing, such certificate may state that it is
given without prejudice to any rights against third parties which exist at the
date thereof or which may subsequently come into being.

         SECTION 3.06. Completion of Projects in event Project Fund inadequate.
If the moneys in the separate account relating to a Project in the Project Fund
created by the Resolution shall not be sufficient to pay the Cost of
Construction of such Project in full (whether due to investment losses or
otherwise), the Corporation shall, subject to the provisions of Section 3.01,
complete such Project and pay (whether through financing or otherwise) all that
portion of the Cost of Construction thereof in excess of the moneys available
therefor in such separate account in the Project Fund. The Authority does not
make any warranty, either express or implied, that the moneys which will be paid
into the Project Fund will be sufficient to pay the Cost of Construction on any
Project. If the Corporation shall pay any portion of the Cost of Construction of
any Project pursuant to the provisions of this Section, it shall not be entitled
to any reimbursement therefor from the Authority, the Trustee or the holders of
any of the Bonds, nor shall it be entitled to any diminution in or postponement
of the payments required to be paid by the Corporation pursuant to this
Participation Agreement or the First Mortgage Bonds.

                                        9

         SECTION 3.07 Ownership and Possession of Projects. Issuance of the
Bonds will not vest in the holders thereof, the Trustee or any other person,
ownership, or the right to possession, of the Project related thereto.

         SECTION 3.08 Operation, maintenance and repair. The Authority and the
Corporation recognize that the Projects constitute integrated portions of the
power plants of the Corporation and that it is not feasible to administer the
Projects separately from such plants. The Corporation shall operate the Projects
(with such changes, improvements or additions as the Corporation may deem
desirable) as part of such plants for the joint useful lives of the Projects and
such plants, and shall maintain and repair the Projects in conformity with the
Corporation's normal maintenance and repair programs for such plants; provided
that the Corporation shall have no obligation to operate, maintain or repair any
element or item of any Project the operation, maintenance, or repair any element
or item of any Project the operation, maintenance, or repair of which becomes
uneconomic to the Corporation because of damage or destruction by a cause not
within the control of the Corporation, or obsolescence (including economic
obsolescence), or change in government standards and regulations, or the
termination or transfer by the Corporation of the operation of the electric
power generation facilities to which the element or item of the Project is an
adjunct. Prior to the transfer by the Corporation of the operation of the
electric power generation facilities to which an element or item of the Project
is an adjunct, the Corporation, the Authority and the Trustee shall receive an
agreement in writing by the transferee that it shall maintain and repair the
Projects in the manner prescribed by this Section 3.08.

         SECTION 3.09. Investment of moneys in funds under the Resolution. Any
moneys held as part of any fund created under the Resolution shall, at the
direction of an Authorized Corporation Representative, be invested or reinvested
by the Trustee as provided in Article VII of the Resolution.

         SECTION 3.10. Disposition of Series A Bond Proceeds. The Corporation
agrees that it will not submit any requisition pursuant to Section 3.03 hereof
which, if paid, would result (upon the expenditure to pay Exempt Costs of the
balance of the proceeds of the Bonds on deposit in the Project Fund after
payment of such requisition) in less than 90 percent of the Net Proceeds of the
Bonds being used to pay Exempt Costs. The Corporation agrees that income on Bond
proceeds held in the Project Fund shall, if not transferred to the Bond Fund
pursuant to Section 5.02 of the Resolution, be used to pay any item of the Cost
of Construction of the Pollution Control Facilities.

         SECTION 3.11. Arbitrage certification with respect to Series A Bonds.
The Corporation hereby certifies and represents to the Authority that it is not
expected that the proceeds of the Series A Bonds will be used in a manner that
would cause the Series A Bonds to be "arbitrage bonds" under Section 103(c) of
the Internal Revenue Code of 1954, as amended, Temporary Treasury Regulations
section 13.4 and Proposed Treasury Regulations section section 1.103-13 and
1.103-14. To the best of the knowledge and belief of the Corporation, there are
no facts, estimates or circumstances that would materially change the foregoing

conclusion.

                                   ARTICLE IV

                        FIRST MORTGAGE BONDS AND PAYMENTS

         SECTION 4.01. Execution and delivery of First Mortgage Bonds to
Trustee. Concurrently with the authentication and delivery by the Authority of
any series of the Bonds and in order to evidence the obligation of the
Corporation to the Authority to repay the advance of the proceeds of such series
of Bonds, the Authority hereby directs the Corporation, and the Corporation
hereby agrees, to execute and deliver to the Trustee its First Mortgage Bonds,
duly and validly authenticated and issued under the Corporation Indenture,
relating to such series of Bonds. Such First Mortgage Bonds shall be in
substantially the form included in the Supplemental Corporation Indenture and
shall:

         (a) be in an aggregate principal amount equal to the aggregate
principal amount of the Bonds then being authenticated and delivered (the
"related Bonds");

         (b) provide for payments of interest equal to the payments of interest
on the related Bonds;

         (c) require payments of principal, or principal plus a premium, if any,
equal to the payments required to be made on the related Bonds;

         (d) contain redemption provisions, including premium, if any, or
provisions with respect to amortization of principal, together with premium, if
any, identical to the redemption or amortization provisions of the related
Bonds; and

         (e) require that all payments of principal, premium, if any, and
interest on the First Mortgage Bonds be made to the Trustee in such coin or
currency of the United States of America as at the time of payment shall be
legal tender for the payment of public and private debts, and that each such
payment be made on or before the due date for the corresponding payment on the
related Bonds.

         The Corporation shall receive a credit against its obligation to pay
the principal of and premium, if any, and interest on, as the case may be, the
Series A First Mortgage Bonds as provided in Section 15.07 of the Resolution.

         SECTION 4.02. Prepayment to redeem Bonds. Whenever any series of the
Bonds is redeemable in whole or in part, the Authority will redeem the same at
the written direction of an Authorized Corporation Representative, and the
Corporation will pay, as a prepayment of the amount due on the First Mortgage
Bonds corresponding to such series of the Bonds, an amount equal to the total
cost of such redemption, less the amount, if any, in the Bond Fund on the date
fixed for such redemption and available and designated for such redemption

         SECTION 4.03. Obligation for payment absolute; deficiencies. The
Corporation agrees that its obligation to make the First Mortgage Bond Payments
at the times and in the amounts provided in the First Mortgage Bonds shall be
absolute, irrevocable and unconditional and shall not be subject to any defense
(other than payment) or any right of setoff, counterclaim or recoupment for any
reason, including, without limitation, the unenforceability (because of judicial
decision or otherwise) or the impossibility of performance of the First Mortgage
Bond obligations, or any breach by the Authority of any obligation to the
Corporation, whether under this Participation Agreement or otherwise, or
inaccuracy of any representation by the Authority to the Corporation under this
Participation Agreement, or any indebtedness or liability at any time owing to
the Corporation by the Authority or any failure to complete any Project, or the
destruction by fire or other casualty of any Project or any portion thereof, or
the taking of title thereto or the use thereof by the exercise of the power of
eminent domain, provided, however, that the foregoing shall not be deemed to be
a waiver of any right of recourse the Corporation may have against the
Authority. If for any reason First Mortgage Bond Payments, together with other
moneys held by the Trustee and then available for such purpose, would not be
sufficient to make the corresponding payments of principal (including sinking
fund installments) of and premium, if any, either at maturity, upon redemption,
by declaration or otherwise and interest on, the Bonds when such payments are
due, the Corporation will pay the amounts required from time to time to make up
any such deficiency.

         SECTION 4.04. Administration Fees; expenses, etc. In order to defray a
portion of the expenses incurred by the Authority in conducting and
administering its programs for the acquisition and construction of pollution
control facilities and the development of advanced technologies, the Corporation
shall pay to the Authority Administration Fees in the following amounts and on
the following dates:

         (a) On the date of authentication and delivery of the Series A Bonds to
the initial purchasers, $22,500; and

         (b) On the date of authentication and delivery of the Series A Bonds,
and on June 1 of each year thereafter so long as any Series A Bonds are
outstanding, the sum of $2,500.

         In addition to such Administration Fees, the Corporation will pay or
reimburse the Authority upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Authority (including printing
costs and the reasonable fees, expenses and disbursements of its counsel and
bond counsel) in connection with (i) the issuance, exchange, registration or
transfer of the Bonds, the temporary Bonds, Additional Bonds or Bonds
representing the unredeemed portion of Bonds called for redemption; (ii) the
performance of Sections 4.02, 4.03, 9.02, 9.03, 9.04 and 9.05 of the Resolution;
(iii) the obtaining and furnishing of information or advice to the Trustee
pursuant to Section 11.04 of the Resolution; (iv) the appointment of successor
Trustees, Paying Agents and successor Paying Agents; (v) the execution and
delivery of Supplemental Participation Agreements; (vi) the adoption of
resolutions supplementing or amending the Resolution;
<PAGE>

and (vii) the release of the Resolution pursuant to Section 14.01 thereof.

         SECTION 4.05. Compensation of Trustee and Paying Agents. The
Corporation agrees to pay to the Trustee until the principal of and premium, if
any, and interest on the Bonds shall have been fully paid: (i) an amount equal
to the initial or acceptance fee of the Trustee and the annual fee of the
Trustee for its ordinary and reasonable services rendered and its ordinary and
reasonable expenses incurred as Trustee under the Resolution, as and when the
same become due; (ii) reasonable fees and charges of the Trustee, as Bond
Registrar, and any Paying Agent, as provided in the Resolution, as and when the
same become due; and (iii) the reasonable fees and charges of the Trustee for
the necessary extraordinary services rendered by it and extraordinary expenses
incurred by it under the Resolution, as and when the same become due, provided
that the Corporation will not be required to pay for any such extraordinary
services or extraordinary expenses so long as it is contesting the same in good
faith.

         SECTION 4.06. Projects not security for Bonds. It is expressly
recognized by the parties that the Projects will not constitute any part of the
security for the Bonds, except to the extent that Project A is subject to the
lien of the Corporation Indenture for the benefit of the holders of all of the
Corporation's first mortgage bonds, including the Series A First Mortgage Bonds.
The principal security for the Bonds shall be the First Mortgage Bonds and the
absolute, irrevocable and unconditional obligation of the Corporation to make
the First Mortgage Bond Payments.

         SECTION 4.07. Payment of taxes and assessments; no liens or charges.
The Corporation will (a) pay, when the same shall become due, all taxes and
assessments, including income, profits, property or excise taxes, if any, or
other municipal or governmental charges, imposed, levied or assessed by the
Federal, state or any municipal government upon the Authority or the Trustee in
respect of any payments (other than payments made pursuant to Sections 4.04 and
4.05) made or to be made pursuant to this Participation Agreement or the First
Mortgage Bonds, and (b) pay or cause to be discharged, within sixty (60) days
after the same shall accrue, any lien or charge upon any such payment made or to
be made under this Participation Agreement, provided that the Corporation shall
not be required to pay any such tax or assessment so long as (i) the Corporation
at its expense contests by appropriate legal proceedings conducted in good faith
and with due diligence the amount, validity or application of any such tax,
assessment or charge, (ii) such proceedings shall have the effect of suspending
the collection thereof from the Authority and the Trustee, and (iii) the
Corporation shall indemnify and hold the Authority and the Trustee harmless from
any losses, costs, charges, expenses (including reasonable attorneys' fees and
disbursements), judgments and liabilities arising in respect of such tax,
assessment or charge and the nonpayment thereof.

         SECTION 4.08. Indemnification of Authority and Trustee. Any obligation
of the Authority created by or arising out of this Participation Agreement shall
be a limited obligation of the Authority, payable solely from the First Mortgage
Bond Payments and any other funds held by the Trustee under the Resolution and
available for such payment, and
<PAGE>

                                       13

shall not constitute an indebtedness of or a charge against the general credit
of the Authority and shall not constitute or give rise to any pecuniary
liability of the Authority; nevertheless, if the Authority shall incur any such
pecuniary liability, then in such event the Corporation shall indemnify and hold
the Authority harmless by reason thereof. The Corporation releases the Authority
and the Trustee from, agrees that the Authority and the Trustee shall not be
liable for, and agrees to indemnify and hold the Authority and the Trustee
harmless from, any liability for any loss or damage to property or any injury to
or death of any person that may be occasioned by any cause whatsoever arising
out of the construction or operation of any Project. The Corporation agrees to
indemnify and hold the Authority, its members, officers and employees and the
Trustee harmless from any losses, costs, charges, expenses (including reasonable
attorneys' fees and disbursements), judgments and liabilities incurred by it or
them, as the case may be, in connection with any action, suit or proceeding
instituted or threatened in connection with the transactions contemplated by
this Participation Agreement so long as it or they, as the case may be, have
acted in good faith to carry out the transactions contemplated by this
Participation Agreement.

         SECTION 4.09. Corporation to pay attorneys' fees and disbursements. If
the Corporation shall default under any of the provisions of this Participation
Agreement and the Authority or the Trustee or both shall employ attorneys or
incur other expenses for the collection of payments due under this Participation
Agreement or for the enforcement of performance or observance of any obligation
or agreement on the part of the Corporation contained in this Participation
Agreement, the Corporation will on demand therefor reimburse the reasonable fees
of such attorneys and such other reasonable disbursements so incurred.

         SECTION 4.10. No abatement of Administration Fees and other charges. It
is understood and agreed that so long as any Bonds are outstanding under the
Resolution, Administration Fees and other charges payable to the Authority
pursuant to this Participation Agreement shall continued to be payable at the
times and in the amounts herein specified, whether or not any Project, or any
portion thereof, shall have been destroyed by fire or other casualty, or title
thereto or the use thereof shall have been taken by the exercise of the power of
eminent domain and that there shall be no abatement of any such Administration
Fees and other charges by reason thereof.

         SECTION 4.11. Prepayment of First Mortgage Bonds. The Corporation shall
not prepay any First Mortgage Bonds or any portion thereof except in connection
with a permitted redemption or repurchase prior to maturity of all or a portion
of the related Bonds or pursuant to Article XIV of the Resolution.

(To Participation Agreement dated as of June 1, 1977 between New York State
Energy Research and Development Authority and Central Hudson Gas & Electric
Corporation)

                            DESCRIPTION OF PROJECT A
                          POLLUTION CONTROL FACILITIES

         The Project A Pollution Control Facilities consist of certain air and
water pollution control facilities and sewage and solid waste disposal
facilities which, together with other facilities, have been constructed at the
Roseton Electric Generating Plant (owned, as tenants in common, by the
Corporation, Consolidated Edison Company of New York, Inc. and Niagara Mohawk
Power Corporation) and at the Corporation's Danskammer Electric Generating
Plant. Both such Plants are located in Orange County, New York, in the
Corporation's franchise area.

ROSETON PLANT

         Dust Collection and Fly Ash Reinjection System. This system is designed
to remove fly ash from boiler exhaust gases and reinject the ash into the boiler
for burning. The dust collector on each boiler consists of a structural
foundation, a support structure, casing inlet and outlet duct connections,
internal dust and gas separating elements, dust collector hoppers, internal flow
dividers, hopper level sensors, hopper outlet valving and interlocking, and
automatic control and sequencing equipment for continual removal of residue
collected in the hoppers. The fly ash reinjection system on each boiler consists
of a transport piping system from the dust collector hoppers to the boiler,
motor driven air blowers and air heaters to supply hot transport air, controls
and instrumentation for motors and heaters, and associated electrical and
pneumatic equipment.

         Waste Water Treatment System. The facilities are designed to remove
pollutants from the process discharge water and consist of lift stations, a
gravity transport line to the waste treatment area, four waste water treatment,
settling and neutralizing basins, transfer pumps, piping, chemical injectors,
skimming and final settling facilities, and associated pumps, piping, controls,
instrumentation and electrical equipment.

         Sewage Treatment System. The sewage treatment system is designed to
treat raw sanitary sewage and consists of a lift station, gravity transport
line, wet wells, a package type sewage treatment plant equipped with aerating
blowers, skimmer, electrical controllers and instrumentation, and associated
piping, pumps, chemical feeders and other controls.

         Fuel Oil Spill Control Facilities. The fuel oil spill control equipment
is designed to prevent spilled oil from contaminating the Hudson River and
consists of a floating boom used to encircle fuel ships and barges during
unloading, a motorboat to tow the boom into place, oil separating and monitoring
pits for drainage from fuel oil storage tank areas, and welded steel envelopes
around storage tanks. A sheet piling baffle extending from above
<PAGE>

                                       18

the river water surface to the river bottom encloses the outlet of the storm and
storage tank farm drain to entrap any oil which may escape from anywhere on the
plant property.

DANSKAMMER PLANT

         Waste Water Treatment Facilities. The facilities are designed to remove
pollutants from the process discharge water. The treatment plant consists of
three basins for settlement of solids and equalization of pH, pumps, piping,
controls and instrumentation.

(To Participation Agreement dated as of June 1, 1977 between New York State
Energy Research and Development Authority and Central Hudson Gas & Electric
Corporation)

                    DESCRIPTION OF OTHER PROJECT A FACILITIES

         The Other Project A Facilities consist of facilities of the Corporation
which are required by the public interest in development, health, recreation,
safety, conservation of natural resources or aesthetics and which have been
constructed at the Roseton Electric Generating Plant (owned by the Corporation,
Consolidated Edison Company of New York, Inc. and Niagara Mohawk Power
Corporation) and at the Corporation's Danskammer Electric Generating Plant. Both
such Plants are located in Orange County, New York, in the Corporation's
franchise area.

ROSETON PLANT

         Smoke Density Meters. These meters will measure the opacity of stack
gases in order to indicate the presence of abnormal boiler burning conditions
which could lead to unacceptable emissions to the atmosphere.

         Yard Drainage System, Fuel Oil Trench and Oil Tank Berm. The yard
drainage system is designed to collect drainage water and channel it to the
Hudson River after any contaminant oil has been separated from the drainage
flow. The fuel oil drainage trench serves to trap any leaks from sunken oil
pipelines and thus prevents the seepage of oil into underground water streams.
The oil tank berm is designed to contain spillage from the Roseton Plant's fuel
oil storage tanks.

DANSKAMMER PLANT

         Fly Ash Reinjection System. The system will serve to collect fly ash
precipitated out of the furnace vent stream and reinject the collected ash into
the furnace chamber. It will consist of positive displacement air blowers, air
heaters and associated valves and piping.

         Stack Testing Platforms. These platforms, which gird the plant stacks
at the level of the stack testing ports, are required in order to facilitate
testing periodically required by the New York State Department of Environmental
Conservation to check compliance with the Department's emission standards.

         Oil Spill Containment System. This system is composed of a boom and
launch that serve to contain and collect oil spills in the Hudson River.

                         THE PROJECT; ISSUANCE OF BONDS

                  SECTION 3.01. THE PROJECT. The Corporation represents that the
Project is complete. The Project belongs to and is the property of the
Corporation. In order to effectuate the purposes of this Participation
Agreement, the Corporation will do or cause to be done all things requisite or
proper for the fulfillment of the obligations of the Corporation under this
Participation Agreement.

practicable after the execution of this Participation Agreement will issue, sell
and deliver the Bonds to the Underwriters thereof, all pursuant to and as
provided in the Bond Purchase Agreement for the Bonds among the Authority, the
Corporation and the Underwriters and will deposit the proceeds of such sale of
the Bonds with the Trustee in the Proceeds Fund.

                  (b) The Bonds shall not be general obligations of the
Authority, and shall not constitute an indebtedness of, or a charge against the
general credit of, the Authority or give rise to any pecuniary liability of the
Authority. The liability of the Authority under the Bonds shall be enforceable
only to the extent provided in the Indenture, and the Bonds shall be payable
solely from the Corporation Note Payments, any payments by the Corporation under
Section 4.11, and any other funds held by the Trustee under the Indenture and
available for such payment. The Bonds shall not be a debt of the State of New
York, and the State of New York shall not be liable thereon.

                  SECTION 3.03. NO INTEREST IN PROJECT CONFERRED. Neither the
Authority nor the Trustee shall be entitled to any interest in the Project by
reason of the advance of Bond proceeds pursuant to this Participation Agreement.

may deem desirable) as part of such facilities for the joint useful life of the
Project and such facilities, shall maintain and repair the Project or cause the
Project to be maintained and repaired in conformity with the Corporation's and
its co-tenants' normal maintenance and repair programs for such facilities and
shall proceed in good faith to maintain the availability of the Project for use
as an authorized project under the Act; but the Corporation and its co-tenants
shall have no obligation to operate, maintain or repair or cause to be operated,
maintained, or repaired, or proceed in good faith to maintain the availability
of the Project for use as an authorized project under the Act with respect to,
any element or item of the Project the operation, maintenance, or repair of
which becomes uneconomic to the Corporation because of damage or destruction or
obsolescence

                                        6
<PAGE>

(including physical, functional and economic obsolescence), or change in
government standards and regulations, or the termination of the operation of the
portion of such facilities to which the element or item of the Project is an
adjunct, or the sale, transfer or other disposition by the Corporation of its
interest in such facilities.

                  SECTION 3.05. SECURITIES DEPOSITORY. The Corporation
acknowledges that the Authority and the Trustee, at the request of the
Corporation, have arranged for the initial deposit of the Bonds with The
Depository Trust Company ("DTC") which will act as Securities Depository in
order to effectuate a book-entry-only system and that this system may be
discontinued or, if discontinued, reinstituted (with DTC or another Securities
Depository) in accordance with the Indenture. The Corporation agrees to take all
actions necessary, and to refrain from taking actions contrary to the
effectuation of a book-entry-only system established pursuant to the Indenture
and any arrangements among the Authority, the Trustee and any Securities
Depository. The Authority shall not enter into any written agreements with a
Securities Depository without receipt and acceptance of such agreements by the
Corporation.

                  SECTION 3.06. INVESTMENTS UNDER THE INDENTURE. Any money held
in any fund under the Indenture shall be invested and reinvested as provided in
the Tax Regulatory Agreement and Article IX of the Indenture.

                                   ARTICLE IV

                  CORPORATION NOTE AND PAYMENTS; CREDIT SUPPORT

                  SECTION 4.01. EXECUTION AND DELIVERY OF CORPORATION NOTE TO
TRUSTEE. (a) Concurrently with the authentication by the Trustee and delivery by
the Authority of the Bonds and in order to evidence the obligation of the
Corporation to the Authority to repay the advance of the proceeds of the Bonds,
the Authority hereby directs the Corporation, and the Corporation hereby agrees,
to execute and deliver to the Trustee its Corporation Note and to duly and
punctually pay the principal of, premium, if any, and interest on, the
Corporation Note at the place, the times and in the manner provided therein. The
Corporation Note shall be substantially in the form attached hereto as Exhibit
A.

                  (b) The obligation of the Corporation to make any payment of
principal of, and premium, if any, and interest on, the Corporation Note shall
not be deemed satisfied and discharged by any payment under the Policy.

                  SECTION 4.02. REDEMPTION OF BONDS. Whenever Bonds are
redeemable in whole or in part, the Authority will redeem the same at the
written direction of an Authorized Corporation Representative given in
accordance with Section 5.01 of the Indenture. Expenses in connection with the
redemption of Bonds shall be paid by the Corporation.

                  SECTION 4.03. OBLIGATION FOR PAYMENT ABSOLUTE; DEFICIENCIES.
The Corporation agrees that its obligation to make the Corporation Note Payments
and payments under Section 4.11 at the times and in the amounts provided in the
Corporation Note and this Participation Agreement shall be absolute, irrevocable
and unconditional and shall not be subject to any defense (other than payment)
or any right of set-off, counterclaim or recoupment for any reason, including,
without limitation, the unenforceability (because of judicial decision or
otherwise) or the impossibility of performance of the Corporation Note
obligations, or any breach by the Authority of any obligation to the
Corporation, whether under this Participation Agreement or otherwise, or
inaccuracy of any representation by the Authority to the Corporation under this
Participation Agreement or in any other instrument, or any indebtedness or
liability at any time owing to the Corporation by the Authority, or the
destruction by fire or other casualty of the Project or any portion thereof, or
the taking of title thereto or the use thereof by the exercise of the power of
eminent domain. If for any reason Corporation Note Payments, together with other
money held by the Trustee and then available for such purpose, would not be
sufficient to make the corresponding payments of principal of, and premium, if
any, and interest on, the Bonds when such payments are due, the Corporation will
pay the amounts required from time to time to make up any such deficiency.

                  SECTION 4.04. ADMINISTRATION FEES; EXPENSES, ETC. In order to
defray a portion of the expenses incurred by the Authority in conducting and
administering its programs for the acquisition and construction of facilities
for the furnishing of electricity, special energy projects and the development
of advanced technologies, the Corporation shall pay to the Authority an initial
Administration Fee in the amount of $83,500 on the date of the authentication
and delivery of the

                                        8

Bonds and an annual fee equal to $130 per million dollar principal amount of the
Bonds on August 1 of each year commencing August 1, 2000, based upon the amount
of Bonds Outstanding as of such August 1 and for purposes of the calculation of
such fee, rounding up to the nearest whole million dollars, and all reasonable
expenses, disbursements, advances, taxes, assessments or impositions, not
otherwise paid under this Participation Agreement or the Indenture, incurred by
or imposed upon the Authority in connection with its administration and
enforcement of, and compliance with, this Participation Agreement and the
Indenture, which amounts the Company is obligated to pay, including, but not
limited to, reasonable attorneys' fees.. In addition, the Corporation shall pay
to the State of New York with respect to the Bonds a bond issuance charge in the
amount of $116,900 on the date of authentication and delivery of the Bonds.

                  SECTION 4.05. COMPENSATION OF FIDUCIARIES. The Corporation
agrees:

                  (1) to pay to the Trustee from time to time upon its request
         reasonable compensation for all services rendered by it in any capacity
         under the Indenture (which compensation shall not be limited by any
         provision of law in regard to the compensation of a trustee of an
         express trust);

                  (2) except as so otherwise expressly provided herein, to
         reimburse the Trustee upon its request for all reasonable expenses,
         disbursements and advances incurred by it in any capacity under the
         Indenture (including the reasonable compensation and the expenses and
         disbursements of its agents and counsel), except any such expense,
         disbursement or advance as may be attributable to its negligence, bad
         faith or willful misconduct; and

                  (3) to pay to the Fiduciaries, other than the Trustee, from
         time to time upon their request, reasonable compensation for all
         services rendered by them under the Indenture and reimburse them for
         their reasonable expenses incurred under the Indenture (including
         reasonable compensation and expenses and disbursements of their agents
         and counsel), except any such expense as may be attributable to their
         negligence, bad faith or willful misconduct.

                  SECTION 4.06. PROJECT NOT SECURITY FOR BONDS. It is expressly
recognized by the parties hereto that neither the Project nor any other property
of the Corporation will constitute any part of the security for the Bonds.

                  SECTION 4.07. PAYMENT OF TAXES AND ASSESSMENTS; NO LIENS OR
CHARGES. The Corporation will (a) pay, when the same shall become due, all taxes
and assessments, including income, profits, property or excise taxes, if any, or
other municipal or governmental charges, imposed, levied or assessed by the
Federal, state or any municipal government upon the Authority or any Fiduciary
in respect of any payments (other than payments made pursuant to Sections 4.04
and 4.05) made or to be made pursuant to this Participation Agreement or the
Corporation Note and (b) pay or cause to be discharged, within 60 days after the
same shall accrue, any lien or charge upon any such payment made or to be made
under this Participation Agreement, provided that the Corporation shall not be
required to pay any such tax or assessment so long as (i) the

                                        9
<PAGE>

Corporation at its expense contests, by appropriate legal proceedings conducted
in good faith and with due diligence, the amount, validity or application of any
such tax, assessment or charge, (ii) such proceedings shall have the effect of
suspending the collection thereof from the Authority or such Fiduciary, and
(iii) the Corporation shall indemnify and hold the Authority and each Fiduciary
harmless from any losses, costs, charges, expenses (including reasonable
attorneys' fees and disbursements), judgments and liabilities arising in respect
of such tax, assessment or charge and the nonpayment thereof.

                  SECTION 4.08. INDEMNIFICATION OF AUTHORITY AND FIDUCIARIES.
Any obligation of the Authority created by or arising out of this Participation
Agreement shall be a limited obligation of the Authority, payable solely from
the Corporation Note Payments, any payments by the Corporation under Section
4.11, funds paid under the Policy and any other funds held by the Trustee under
the Indenture and available for such payment, and shall not constitute an
indebtedness of or a charge against the general credit of the Authority and
shall not constitute or give rise to any pecuniary liability of the Authority;
nevertheless, if the Authority shall incur any such pecuniary liability, then in
such event the Corporation shall indemnify and hold the Authority harmless by
reason thereof. The Corporation releases the Authority and the Fiduciaries from,
agrees that the Authority and the Fiduciaries and the Indexing Agents shall not
be liable for, and agrees to indemnify and hold the Authority and the
Fiduciaries harmless from, any liability for any loss or damage to property or
any injury to or death of any person that may be occasioned by any cause
whatsoever arising out of the construction or operation of the Project. The
Corporation agrees to indemnify and hold the Authority, its members, officers
and employees and the Fiduciaries harmless from any losses, costs, charges,
expenses (including reasonable attorneys' fees and disbursements), judgments and
liabilities incurred by it or them, as the case may be, in connection with any
claims made, or any action, suit or proceeding instituted or threatened, in
connection with the transactions contemplated by this Participation Agreement or
the Indenture (i) so long as, in the case of the Authority, its members,
officers and employees, it or they, as the case may be, have acted in good faith
to carry out the transactions contemplated by this Participation Agreement and
the Indenture and (ii) so long as, in the case of the Fiduciaries, it or they
shall not have acted negligently, in bad faith or with willful misconduct in
carrying out the transactions contemplated by this Participation Agreement and
the Indenture.

the Project, or as to the suitability of the Project for the Corporation's
purposes or needs.

this Participation Agreement.

                  SECTION 5.03. CORPORATION CONSENT TO AMENDMENT OF INDENTURE.
The Authority shall not enter into any indenture supplemental to or amendatory

provision hereof, the Corporation covenants and agrees that it will not take or
authorize or permit any action to be taken with respect to the Project, or the
proceeds of Bonds, including any amounts treated as proceeds of the Bonds for
any purpose of Section 103 of the Code, which will result in the loss of the
exclusion of interest on the Bonds from gross income for Federal income tax
purposes under Section 103 of the Code (except for any Bond during any period
while any such Bond is held by a person referred to in Section 147(a) of the
Code). This provision shall control in case of conflict or ambiguity with any
other provision of this Participation Agreement. In furtherance of such covenant
and agreement, the Authority and the Corporation have entered into the Tax

assessments, and governmental liens, claims and other charges at any time
lawfully imposed or accruing upon or against the Corporation or upon or against
its properties or any part thereof, or upon the income derived therefrom or from
the operations of the Corporation, provided that the Corporation shall not be
required to pay or discharge, or cause to be paid or discharged, any such
obligation, tax, rate, levy, assessment, lien, claim or other charge so long as
in good faith and by appropriate legal proceedings the validity thereof shall be
contested.

                  SECTION 5.09. MAINTENANCE OF PROPERTIES. The Corporation will
at all times make or cause to be made such expenditures for repairs, maintenance

good repair, working order and condition as an operating system or systems to
the extent necessary to meet the Corporation's obligations under the Public
Service Law of the State of New York and this Participation Agreement; provided,
however, that nothing herein contained shall be construed to prevent the
Corporation from ceasing to own or operate any of its plants or any other
property, if, in the judgment of the Corporation, it is advisable not to own or
operate the same and the ownership or operation thereof shall not be essential
to the maintenance and continued operation of the rest of the operating system
or systems, and the security under the Indenture afforded by the Corporation
Note will not be substantially impaired by the termination of such operation.

                  SECTION 5.10. INSURANCE. The Corporation will keep or cause to
be kept such parts of its properties as, in the opinion of an Authorized
Corporation Representative (who shall for this purpose be a professional
experienced in corporate risk management or a licensed professional engineer),
are of an insurable nature, insured against loss or damage by fire or other
casualties, the risk of which is customarily insured against by companies
similarly situated and operating like properties, to the extent that property of
similar character is customarily insured against by such companies, either (a)
by reputable insurers or (b) in whole or in part in the form of reserves or of
one or more insurance funds created by the Corporation, whether alone or with
other corporations.

keeping accounts or the rules, regulations or orders prescribed by a regulatory
commission with

his knowledge, information and belief, the Corporation has kept, observed,
performed and fulfilled or caused to be kept, observed, performed and fulfilled
each and every one of its covenants and obligations contained in this
Participation Agreement and in the Corporation Note and, to the best of his
knowledge, information and belief, there does not exist at the date of such
certificate any default by the Corporation under this Participation Agreement or
any event of default hereunder or other event which, with notice or the lapse of
time specified in Section 6.01, or both, would become an event of default or, if
any such default or event of default or other event shall so exist, specifying
the same and the nature and status thereof.

instrumentality of any government or political subdivision thereof (each, a
"Person") or Persons or convey, transfer, lease or otherwise dispose of all or
substantially all of its properties and assets (any such conveyance, transfer,
lease or other disposition, a "Transfer"), except in the manner and upon the
terms and conditions set forth in this Section 5.14.

                  (b) Nothing contained in this Participation Agreement shall

authorizing) any lawful consolidation or merger of the Corporation with or into
any other Person lawfully authorized to acquire and operate the properties of
the Corporation, or a series of consolidations or mergers, or successive
consolidations or mergers, in which the Corporation or its successor or
successors shall be a party, or any Transfer to a Person lawfully authorized to
acquire and operate the same; provided that upon any consolidation, merger or
Transfer, the Person formed by such consolidation, or into which such merger may
be made if other than the Corporation, or the Person that is a transferee in a
Transfer shall execute and deliver to the Trustee an instrument, in form
satisfactory to the Trustee, whereby such Person shall effectually assume the
due and punctual payment of the principal of, and premium, if any, and interest
on, the Corporation Note according to its tenor and the due and punctual
performance and observance of all covenants and agreements to be performed by
the Corporation pursuant to this Participation Agreement, the Tax Regulatory

                  (c) Every such successor Person (or transferee Person under
Section 7.06) shall possess, and may exercise, from time to time, each and every
right and power of the Corporation hereunder and under the Note, in its name or
otherwise; and any act, proceeding, resolution or certificate by any of the
terms of this Participation Agreement, the Tax Regulatory Agreement and the
Corporation Note required or provided to be done, taken and performed or made,
executed or verified by any board or officer of the Corporation shall and may be
done, taken and performed or made, executed or verified with like force and

                  SECTION 5.16. COMPLIANCE WITH LAWS. The Corporation agrees to
use its best efforts to comply in all material respects with all applicable
laws, rules and regulations and orders of any governmental authority,

Agreement or the Corporation Note, except laws, rules, regulations or orders
being contested in good faith or laws, rules, regulations or orders for which
the Corporation has applied for variances from or exceptions to.

                        DEFAULTS BY CORPORATION; REMEDIES

                  SECTION 6.01. EVENTS OF DEFAULT; ACCELERATION. In case one or
more of the following events of default (each, an "event of default") shall have
occurred and be continuing:

                  (a) failure by the Corporation to pay when due any amount
         required to be paid under this Participation Agreement or the
         Corporation Note, which failure causes a default in the payment when
         due of the interest on any of the Bonds and continuance of such default
         for five Business Days;

                  (b) failure by the Corporation to pay when due any amount
         required to be paid under this Participation Agreement or the
         Corporation Note, which failure causes a default in the payment when
         due of the principal of, or premium, if any, on any of the Bonds;
         provided that, with respect to any payment of principal of, or premium,
         if any, payable on Bonds called for redemption, such failure by the
         Corporation shall continue for five Business Days; or

                  (c) failure on the part of the Corporation duly to observe or
         perform any other of the covenants or agreements on the part of the
         Corporation contained in this Participation Agreement (other than
         failure to pay amounts required to be paid under Sections 4.04, 4.05,
         4.07, 4.08, 4.09 or 4.10) or in the Corporation Note for a period of 90
         days after the date on which written notice of such failure, requiring
         the Corporation to remedy the same, shall have been given to the
         Corporation by the Authority or the Trustee, provided, however, that,
         if such failure is such that it cannot be corrected within such 90-day
         period, it shall not constitute an event of default if corrective
         action is instituted by the Corporation within such 90-day period and
         diligently pursued until such failure is corrected; or

                  (d) an Act of Bankruptcy relating to the Corporation;

then, and in any such event, the Trustee with the consent of the Bond Insurer,
may, and upon the written request of the Bond Insurer or the owners of at least
25% in aggregate principal amount of the Bonds then outstanding with the consent
of the Bond Insurer shall, by notice in writing to the Corporation and the Bond
Insurer and provided that the default has not theretofore been cured, declare
the Corporation Note to be due and payable immediately, and upon any such
declaration the same shall become and shall be immediately due and payable,
anything contained in this Participation Agreement or in the Corporation Note to
the contrary notwithstanding. Any amounts collected by the Trustee pursuant to
action taken under this Section 6.01 shall be applied in accordance with the
Indenture. In addition, if at any time the principal of the Bonds shall have
been declared to be due and payable by acceleration pursuant to the terms of the
Indenture, the Corporation Note shall thereupon become and be immediately due
and payable, subject to such declaration with respect to the Bonds being
rescinded or annulled pursuant to the Indenture.

                                       16
<PAGE>

                  The right or obligation of the Trustee to make any such
declaration as aforesaid, however, is subject to the condition that if, at any
time after declaration, but before all the Bonds shall have matured by their
terms, the principal of, premium, if any, and interest on, the Corporation Note
which shall have become due and payable otherwise than by such declaration, and
all other sums payable hereunder, except the principal of, and interest on, the
Corporation Note which shall have become due and payable by such declaration,
shall have been paid or provision satisfactory to the Trustee shall have been
made for such payment, and the reasonable expenses of the Trustee and of the
owners of the Bonds incurred pursuant to the Indenture shall have been paid,
including reasonable attorneys' fees paid or incurred, and all defaults
hereunder and under the Bonds or under the Indenture, except as to the payment
of principal and interest due and payable solely by reason of such declaration,
shall be made good or be secured to the satisfaction of the Trustee or provision
deemed by the Trustee to be adequate shall be made therefor, then and in every
such case the owners of a majority in aggregate principal amount of the Bonds
then outstanding, by written notice to the Authority and to the Trustee, may
rescind such declaration and annul such default in its entirety, or, if the
Trustee shall have acted in the absence of a written request of the owners of at
least 25% in aggregate principal amount of the outstanding Bonds, and if there
shall not have been theretofore delivered to the Trustee written direction to
the contrary by the owners of at least 25% in aggregate principal amount of the
outstanding Bonds, then any such declaration shall ipso facto be deemed to be
rescinded and any such default and its consequences shall ipso facto be deemed
to be annulled, but no such rescission and annulment shall extend to or affect
any subsequent default or impair or exhaust any right or power consequent
thereon.

                  Anything in this Participation Agreement to the contrary
notwithstanding, upon the occurrence and continuance of an event of default as
defined herein, the Bond Insurer (if not in default) shall be entitled to
control and direct the enforcement of all rights and remedies granted to the
Bondholders or the Trustee for the benefit of the Bondholders under this
Participation Agreement, including, without limitation: (i) the right to
accelerate the principal of the Corporation Note as described in this
Participation Agreement, and (ii) the right to rescind any declaration of
acceleration, and the Bond Insurer shall also be entitled to approve all waivers
of events of default.

                  In case the Trustee shall have proceeded to enforce any right
under this Participation Agreement or the Corporation Note and such proceedings
shall have been discontinued or abandoned for any reason or shall have been
determined adversely to the Trustee, then and in every such case the
Corporation, the Authority and the Trustee shall be restored respectively to
their former positions and rights hereunder, and all rights, remedies and powers
of the Corporation, the Authority and the Trustee shall continue as though no
such proceedings had been taken.

                  In the event of any Act of Bankruptcy, reorganization or
liquidation, the Bond Insurer shall have the right to vote on behalf of all
Bondholders absent a default by the Bond Insurer under the Policy.

                  SECTION 6.02. CERTAIN EVENTS OF DEFAULT; AUTHORITY OR TRUSTEE
MAY TAKE CERTAIN ACTIONS. In case the Corporation shall have failed to comply
with its obligations under Article III or under Sections 4.04, 4.08, 4.09, 4. 10
or 5.16, which event shall have continued for a period of 90 days after the date
on which written notice of such failure, requiring the Corporation to remedy the
same, shall have been given to the Corporation by the Authority or the Trustee,
the Authority or the Trustee may take whatever action at law or in equity as may
appear necessary or desirable to enforce performance or observance of any
obligations or agreements of the Corporation under said Article or Sections. In
case the Corporation shall have failed to comply with its obligations under
Section 4.05, which event shall have continued for a period of 90 days after the
date on which written notice of such failure, requiring the Corporation to
remedy the same, shall have been given to the Corporation by the Trustee, the
Trustee may take whatever action at law or in equity as may appear necessary or
desirable to the Trustee to enforce performance or observance of any obligations
or agreements of the Corporation under said Section.

                  SECTION 6.03. JUDICIAL PROCEEDINGS BY TRUSTEE. Upon the
occurrence and continuance of an event of default (as defined in Section 6.01)
the Trustee may, and upon the written request of the owners of at least 25% in
aggregate principal amount of the Bonds then outstanding and receipt by the
Trustee of indemnity satisfactory to it shall, institute any actions or
proceedings at law or in equity for the collection of any amounts then due and
unpaid on the Corporation Note, and may prosecute any such action or proceeding
to judgment or final decree, and may collect in the manner provided by law the
money adjudged or decreed to be payable.

Agreement shall inure to the benefit of and shall be binding upon the Authority,

the amendment thereof, to the Trustee pursuant to the Indenture, as security for
payment of the principal of, and premium, if any, and interest on, the Bonds. In
addition, the Trustee shall have the same power as the Authority to enforce from
time to time the rights of the Authority set forth in Article III and Section
5.16, subject to the provisions of this Participation Agreement relating to the

not sell, assign, transfer, convey or otherwise dispose of its interest in this
Participation Agreement during the term of this Participation Agreement.

dispose of the Project provided that such conveyance, transfer, lease or other
disposition will not release the Corporation from its obligations under this
Participation Agreement except in accordance with the next paragraph.

                  The Corporation may convey, transfer, lease or otherwise
dispose of the Project and be released from its obligations under this
Participation Agreement, the Tax Regulatory Agreement and the Corporation Note,

         transfer, lease or other disposition upon receipt of (i) Opinion of
         Bond Counsel to the effect that the conveyance, transfer, lease or
         other disposition will not have an adverse effect on the exclusion of
         interest on such Bonds from gross income for federal income tax
         purposes and (ii) other legal opinions and documents satisfactory to it
         under the circumstances.

                  (b) The Person that is a transferee of the Project shall
         execute and deliver to the Trustee an instrument, in form satisfactory
         to the Authority and the Trustee, whereby such Person shall effectually
         assume the due and punctual payment of the principal of, and premium,

                  Central Hudson Gas & Electric Corporation (the "Corporation"),
a New York corporation, for value received, hereby promises to pay, on or before
the dates set forth below, the amounts set forth below, to United States Trust
Corporation of New York, New York, New York, as trustee or its successor or
successors as trustee (the "Trustee") under the Trust Indenture dated as of July
15, 1999, between the New York State Energy Research and Development Authority
(the "Authority"), a body corporate and politic, constituting a public benefit
corporation, established and existing under and by virtue of the laws of the
State of New York, and the Trustee. Such Trust Indenture, as it may be amended
or supplemented from time to time, is herein called the "Indenture." Unless
otherwise defined herein, the terms used in this promissory note (the
"Corporation Note") which are defined in Section 1.01 of the Indenture shall
have the meanings, respectively, herein which such terms are given in said
Section 1.01 of the Indenture.

                  This Corporation Note is issued pursuant to the Participation
Agreement in order to evidence the obligation of the Corporation to the
Authority to repay the advance of the proceeds of the Bonds. In accordance with
the Participation Agreement, the Authority has authorized and directed the
Corporation to issue this Corporation Note payable to the order of the Trustee
as security for the payment of principal of, premium, if any, and interest on,

and insofar as the obligations of the Corporation under Section 4.07 relate to
taxes and assessments imposed upon the Authority and not the Fiduciaries,
Section 4.07 thereof), subject to the provisions of the Participation Agreement
relating to the amendment thereof, have been assigned to the Trustee pursuant to
the Indenture. In addition, the Authority has granted the Trustee the same power
as the Authority to enforce from time to time the rights of the Authority set
forth in said Article III and Section 5.16, subject to the provisions of the
Participation

Agreement relating to the amendment thereof. All of the terms, conditions and
provisions of the Participation Agreement are, by this reference thereto,
incorporated herein as part of this Corporation Note.

                  This Corporation Note shall be payable as to principal,
premium, if any, and interest as follows:

                  (a) On or before each Interest Payment Date, a sum which
         together with other money then available for such purpose in the Bond
         Fund will enable the Trustee to pay the interest on the Bonds coming
         due on such date;

                  (b) On or before any redemption date for the Bonds (other than
         a redemption date pursuant to Section 5.05 of the Indenture), a sum
         which together with other money then available for such purpose in the
         Bond Fund will enable the Trustee to pay the principal of, premium, if
         any, and interest on the Bonds which are to be redeemed on such date;
         and

                  (c) On or before August 1, 2027, a sum which together with
         other money then available for such purpose in the Bond Fund will
         enable the Trustee to pay the outstanding principal amount of the
         Bonds;

provided that, if the Bonds are redeemed pursuant to Section 5.05 of the
Indenture, the amounts that would otherwise have been payable on this
Corporation Note if not for such redemption, shall continue to be payable at the
times and in the amounts set forth above as if such redemption had not occurred;
and provided further that if the Bonds are redeemed pursuant to Section 5.05 of
the Indenture the Corporation shall have the right at any time thereafter to
prepay this Corporation Note by paying the amount due on this Corporation Note
at the time of such prepayment together with unpaid interest accrued thereon to
the date of such prepayment.

                  The obligation of the Corporation to make any payment of
principal of, and premium, if any, and interest on, this Corporation Note shall
not be deemed satisfied and discharged to the extent of any corresponding
payment made by the Bond Insurer.

                  All payments of principal of, and premium, if any, and
interest on, this Corporation Note shall be made by wire transfer in immediately
available funds to the Trustee at its corporate trust office, 114 West 47th

                  The Corporation has agreed in the Participation Agreement that
if for any reason Corporation Note Payments, together with other moneys held by
the Trustee and then available for such purpose would not be sufficient to make
the corresponding payments of principal of, and premium, if any, and interest
on, the Bonds when such payments are due, the Corporation will pay the amounts
required from time to time to make up any such deficiency.

                  In the event that payment has been made in respect of the
principal of and premium, if any, and interest on, all of the Bonds, or
provision therefor has been made in accordance with the Indenture, then this
Corporation Note shall be deemed paid in full and shall be cancelled and
returned to the Corporation; provided that this Corporation Note shall not be
deemed paid in full if the Bonds are redeemed pursuant to Section 5.05 of the
Indenture.

                  No reference herein to the Participation Agreement shall
impair the obligation of the Corporation to pay the principal of and premium, if
any, and interest on this Corporation Note at the time and place and in the
amounts herein prescribed, which obligation is absolute, irrevocable and
unconditional and is not subject to any defense (other than payment) or any
right of set-off, counterclaim or recoupment for any reason, including, without
limitation, any breach by the Authority of any obligation to the Corporation,
whether under the Participation Agreement or otherwise, or inaccuracy of any
representation by the Authority to the Corporation under the Participation
Agreement, or any indebtedness or liability at any time owing to the Corporation
by the Authority or any failure to complete the Project or the destruction by
fire or other casualty of the Project or any portion thereof, or the taking of
title thereto or the use thereof by the exercise of the power of eminent domain.

                  In case of an event of default (as defined in Section 6.01 of
the Participation Agreement), the principal of and interest to the date of
payment of this Corporation Note may be declared immediately due and payable as
provided in the Participation Agreement. In addition, if at any time the
principal of the Bonds shall have been declared to be due and payable by
acceleration pursuant to the terms of the Indenture, this Corporation Note shall
thereupon become and be immediately due and payable, subject to such declaration
with respect to the Bonds being annulled pursuant to the Indenture.

                  This Corporation Note may not be amended except by an
instrument in writing signed by the Corporation, by the Authority and by the
Trustee, on behalf of the owners of the Bonds, in the manner and subject to the
conditions provided in the Indenture.

                  This Corporation Note may not be transferred by the Trustee
except to effect an assignment to a successor Trustee under the Indenture or
pursuant to Section 5.05 of the Indenture.
