LONG-TERM EQUITY INCENTIVE PLAN
(2006 Plan) The CH
Energy Group, Inc. Long-Term Equity Incentive Plan (the Plan) is amended,
effective December 31, 2007, as follows: 1.     The
introductory language to the definition of Change in Control contained in
Section 2 of the Plan is hereby superseded and replaced in its entirety as set
forth below: Change in
Control means if at any time any of the following events
shall have occurred (except as may be otherwise prescribed by the Board in an
Evidence of Award): 2.     The
definition of Subsidiary contained in Section 2 of the Plan is hereby
superseded and replaced in its entirety as set forth below: Subsidiary
 means a corporation, company or other entity which is designated by the Board
 and in which the Company has a direct or indirect ownership or other equity
 interest, provided, however, that (i) for purposes of determining whether any
 person may be a Participant with respect to any grant of Incentive Stock
 Options, the term Subsidiary has the meaning given to such term in Section
 424 of the Code, as interpreted by the regulations thereunder and applicable
 law; and (ii) for purposes of determining whether any person may be a
 Participant with respect to any grant of Option Rights or Appreciation Rights
 that are intended to be exempt from Section 409A of the Code, the term
 Subsidiary means any corporation or other entity as to which the Company is an
 eligible issuer of service recipient stock (within the meaning of 409A of the Code).3.       Section
 12 of the Plan is hereby superseded and replaced in its entirety as set forth
 below:12.          Adjustments.
 The Board shall make or provide for such adjustments in the numbers of Common
 Shares covered by outstanding Option Rights, Appreciation Rights, Performance
 Shares, Restricted Stock Units and share-based awards described in Section 10
 of this Plan granted hereunder, in the Option Price and Base Price provided
 in outstanding Option Rights and Appreciation Rights, and in the kind of
 shares covered thereby, as the Board, in its sole discretion, exercised in
 good faith, may determine is equitably required to prevent dilution or
 enlargement of the rights of Participants or Optionees that otherwise would
 result from (a) any stock dividend, stock split, combination of shares,
 recapitalization or other change in the capital structure of the Company, or (b)
 any merger, consolidation, spin-off, split-off, spin-out, split-up,
 reorganization, partial or complete liquidation or other distribution of
 assets (including, without limitation, a special or large non-recurring
 dividend), issuance of rights or    warrants to purchase securities, or (c) any other corporate
 transaction or event having an effect similar to any of the foregoing.
 Moreover, in the event of any such transaction or event, the Board, in its
 discretion, may provide in substitution for any or all outstanding awards
 under this Plan such alternative consideration (including cash) as it, in
 good faith, may determine to be equitable in the circumstances and may
 require in connection therewith the surrender of all awards so replaced. The
 Board may also make or provide for such adjustments in the numbers of shares
 specified in Section 3 of this Plan as the Board in its sole discretion,
 exercised in good faith, may determine is appropriate to reflect any
 transaction or event described in this Section 12; provided, however, that
 any such adjustment to the number specified in Section 3(c)(i) shall be made
 only if and to the extent that such adjustment would not cause any Option
 Right intended to qualify as an Incentive Stock Option to fail so to qualify.
 In no event shall any adjustment be required under this Section 12 if the
 Board determines that such action could cause an award to fail to satisfy the
 conditions of an applicable exception from the requirements of Section 409A
 of the Code or otherwise could subject a Participant to the additional tax
 imposed under Section 409A of the Code in respect of an outstanding award.4.       Section
 18 of the Plan is hereby superseded and replaced in its entirety as set forth
 below:18. Compliance
 with Section 409A of the Code. Awards granted under this Plan
 shall be designed and administered in such a manner that they are either
 exempt from the application of, or comply with, the requirements of Section
 409A of the Code. To the extent that the Board determines that any award
 granted under the Plan is subject to Section 409A of the Code, the Evidence
 of Award shall incorporate the terms and conditions necessary to avoid the
 imposition of an additional tax under Section 409A of the Code upon a
 Participant. Notwithstanding any other provision of the Plan or any Evidence
 of Award (unless the Evidence of Award provides otherwise with specific
 reference to this Section), an award shall not be granted, deferred,
 accelerated, extended, paid out, settled, substituted or modified under this
 Plan in a manner that would result in the imposition of an additional tax
 under Section 409A of the Code upon a Participant. Although the Company
 intends to administer the Plan so that awards will be exempt from, or will
 comply with, the requirements of Section 409A of the Code, the Company does
 not warrant that any award under the Plan will qualify for favorable tax
 treatment under Section 409A of the Code or any other provision of federal,
 state, local, or non-United States law. Neither the Company, its
 Subsidiaries, nor their respective directors, officers, employees or advisers
 shall be liable to any Participant or any other person for any tax, interest,
 or penalties the Participant might owe as a result of the grant, holding,
 vesting, exercise, or payment of any award under the Plan. Any reference in
 this Plan to Section 409A of the Code will also include the applicable
 proposed, temporary or final regulations, or any other guidance, issued with
 respect to such Section by the U.S. Department of the Treasury or the
 Internal Revenue Service.2
