                             STOCK OPTION AGREEMENT
                         YORK INTERNATIONAL CORPORATION
                             2002 OMNIBUS STOCK PLAN

      THIS AGREEMENT is entered into as of the "Date", by and between YORK
INTERNATIONAL CORPORATION, a Delaware corporation ("Company") and "Name"
("Optionee"). Except as otherwise provided in this Agreement, all capitalized
terms shall have the meanings prescribed by the York International Corporation
Amended and Restated 2002 Omnibus Stock Plan ("Plan").

      1.    GRANT OF STOCK OPTION. The Company hereby confirms its grant on
("Grant Date") to Optionee pursuant to the Plan of a stock option ("Option") to
purchase up to "Amount" shares of the Company's Common Stock, par value $0.005
per share ("Common Stock") upon the terms and subject to the terms and
conditions set forth herein and in the Plan.

      2.    OPTION PRICE. The option price per share of Common Stock subject to
the Option shall be "Price", which price is not less than one hundred percent
(100%) of the Fair Market Value of a share of Common Stock on the Grant Date.

      3.    TYPE OF OPTION. The Option shall not be treated as an "incentive
stock option" within the meaning of Section 422 of the Code.

      4.    EXERCISABILITY OF OPTION. Prior to termination pursuant to Section 5
below, the Option shall become exercisable with respect to one-third of the
shares subject to the Option on each of the first three anniversaries of the
Grant Date. In the event the Option is not divisible by three, the first two
portions vesting will be rounded down to the nearest whole number and the last
portion will be rounded up to the nearest whole number.

      5.    TERMINATION OF OPTION. Any unexercised portions of the Option shall
terminate and cease to be exercisable on the earliest of the occurrence of any
of the following events: (i) the tenth anniversary of the Grant Date; (ii) the
third anniversary of the Optionee's Retirement; (iii) the day immediately
preceding the Optionee's termination of employment for Cause; (iv) the third
anniversary of the date on which the Optionee terminates employment on account
of Disability; (v) the ninetieth day after the Optionee terminates employment
with the Company for any reason other than Retirement, Cause, Disability or
Death; and (vi) the third anniversary of the date of the Optionee's death which
occurs prior to his termination of employment. Notwithstanding the foregoing, if
the Optionee dies within the period following termination of employment with the
Company during which the Option was exercisable pursuant to clause (ii), (iv) or
(v) of this Section 5, such period shall be extended until the first anniversary
of the Optionee's death, subject to earlier termination pursuant to clause (i)
of this Section 5.

      6.    PERSONS WHO MAY EXERCISE OPTION. To the extent the Option is
exercisable during the Optionee's lifetime, it may be exercised only by the
Optionee, unless the Optionee has suffered a Disability, in which event the
Option may be exercised only by his legally appointed guardian or legal
representative. To the extent the Option is exercisable after the Optionee's
death, the Option may be exercised only by the Optionee's personal
representative, legatee or distributee, as the case may be.

      7.    MANNER OF EXERCISE AND PAYMENT OF OPTION PRICE. To the extent
exercisable, the Option may be exercised, in whole or in part, by written notice
of the exercise given to the Company at its principal office accompanied by
payment of the exercise price of the shares to be acquired. Payment may be made
in cash or, unless otherwise determined by the Company, in shares or a
combination of cash and shares of Common Stock. The Fair Market Value of shares
of Common Stock delivered on exercise of the Option shall be the Fair Market
Value on the date of exercise. Shares of Common Stock delivered in payment of
the exercise price must be already owned shares that have been held for at least
six months. Any fractional share will be paid in cash. Unless otherwise
determined by the Company and subject to such rules as the Company may
prescribe, the Optionee also may deliver Common Stock, including shares acquired
upon exercise of the Option, in satisfaction of the minimum amount the Company
or any subsidiary is required to withhold for taxes in connection with the
exercise of the Option subject, if the Optionee is subject to Section 16(b) of
the Securities Exchange Act of 1934, to such restrictions as may be imposed from
time to time by the Securities and Exchange Commission to comply with Section
16(b). The withholding tax obligation that may be paid by withholding or
delivery of shares of Common Stock may not exceed the Optionee's minimum
federal, state and local income tax obligations in connection with the exercise
of the Option or the sale of shares of Common Stock received upon exercise of
the Option. The Fair Market Value of the shares of Common Stock to be withheld
or delivered will be the Fair Market Value on the date as of which the amount of
tax to be withheld is determined.

      8.    TRANSFERABILITY. The Option shall not be transferable by the
Optionee other than by will or laws of descent and distribution.

      9.    RELATIONSHIP TO PLAN. The Option contained in this Agreement has
been granted pursuant to the Plan and is in all respects subject to the terms
and conditions of the Plan. The Optionee hereby accepts the Option subject to
all of the terms and conditions of the Plan and agrees that all decisions and
interpretations of the Plan and this Agreement by the Committee or the Board of
Directors of the Company shall be final, binding and conclusive upon the
Optionee and his heirs and distributees.

      10.   NONCOMPETITION/NONSOLICITATION. In consideration of the grant of the
Option, the Optionee agrees as follows:

            (a)   For two years after the termination of the Optionee's
employment with the Company for Cause or as a result of a voluntary resignation,
Optionee will not directly or indirectly, own, manage, operate, control or
participate in the ownership, management, operation or control of or be
connected as an officer, employee, partner, director, consultant or otherwise
with, or have any financial interest in, any business which is in competition
with the business conducted by the Company or its affiliates anywhere in the
world where the Company or its affiliates does business. Ownership for personal
investment purposes only of less than 2% of the voting stock of any publicly
held corporation shall not constitute a violation hereof.

            (b)   For two years after the termination of the Optionee's
employment with the Company for Cause or as a result of a voluntary resignation,
the Optionee will not, directly or indirectly, on behalf of the Optionee or any
other person or entity, solicit for employment or other commercial engagement
any person employed by the Company or its affiliates as of the date of the
solicitation or for the preceding six months.

            (c)   During the period the Optionee is employed by the Company and
at any time thereafter, the Optionee shall not, directly or indirectly, engage
in any conduct or make any statement, whether in commercial or noncommercial
speech, disparaging or criticizing in any way the Company or its affiliates, or
any products or services offered by any of these, nor shall he engage in any
other conduct or make any other statement that could be reasonably expected to
impair the goodwill of any of them.

            (d)   (i)   The Optionee acknowledges and agrees that the
restrictions contained in this Section 10 are reasonable and necessary to
protect and preserve the legitimate interests, properties, goodwill and business
of the Company, and that irreparable injury will be suffered by the Company
should the Optionee breach any of the provisions of this Section 10. The
Optionee represents and acknowledges that (1) the Optionee has been advised by
the Company to consult the Optionee's own legal counsel in respect of this
Agreement, (2) the Optionee has had full opportunity, prior to execution of this
Agreement, to review thoroughly this Agreement with the Optionee's counsel, and
(3) the provisions of this Section 10 are reasonable and these restrictions do
not prevent the Optionee from earning a reasonable livelihood.

                  (ii)  The Optionee further acknowledges and agrees that a
breach of any of the restrictions in this Section 10 cannot be adequately
compensated by monetary damages. The Optionee agrees that the Company shall be
entitled to preliminary and permanent injunctive relief, without the necessity
of proving actual damages, as well as provable damages and an equitable
accounting of all earnings, profits and other benefits arising from any
violation of this Section 10 which rights shall be cumulative and in addition to
any other rights or remedies to which the Company may be entitled. In the event
that any of the provisions of this Section 10 should ever be adjudicated to
exceed the time, geographic, service, or other limitations permitted by
applicable law in any jurisdiction, it is the intention of the parties that the
provision shall be amended to the extent of the maximum time, geographic,
service, or other limitations permitted by applicable law, that such amendment
shall apply only within the jurisdiction of the court that made such
adjudication and that the provision otherwise be enforced to the maximum extent
permitted by law. The time periods set forth above shall be tolled during any
period of violation by the Optionee.

                  (iii) The Optionee irrevocably and unconditionally (1) agrees
that any suit, action or other legal proceeding arising out of this Section 10,
including without limitation, any action commenced by the Company for
preliminary and permanent injunctive relief and other equitable relief, may be
brought in the Court of Common Pleas of York County, Pennsylvania or if such
court does not have jurisdiction or will not accept jurisdiction, in any court
of general jurisdiction in Pennsylvania, (2) consents to the non-exclusive
jurisdiction of any such court in any such suit, action or proceeding, and (3)
waives any objection which the Optionee may have to the laying of venue of any
such suit, action or proceeding in any process, pleadings, notices or other
papers in a manner permitted by the notice provisions of this Section 10.

      11.   GOVERNING LAW. This Agreement shall be subject to and construed in
accordance with the substantive laws (and not the laws of conflicts) of the
State of Delaware, with the exception of Section 10, which shall be construed in
accordance with the substantive laws (and not the laws of conflicts) of the
Commonwealth of Pennsylvania.
