Each Installment shall be paid to Grantee within five (5) business days of the
applicable Vesting Date for such Installment as follows: 60% of the value of the
Installment shall be in the form of shares of Common Stock and 40% of the value
of the Installment (inclusive of withholding of any required income tax

Installment shall be the product of (i) the number of shares for such
Installment as set out in the above table, and (ii) the closing price of the
shares of Common Stock on The New York Stock Exchange, Inc. Composite
Transactions Reporting System ("NYSE") on the Vesting Date or, if the Vesting
Date is not a day on which the NYSE is open for trading, the last business day
preceding the 


                                       1
   2

Vesting Date when the NYSE is open for trading. Except as otherwise provided in
subparagraph (d) through (e) below, Grantee shall not be entitled to any payment
with respect to any Installment unless Grantee is employed by the Company on the
applicable Vesting Date.

                  (c) If, prior to any Vesting Date, Grantee elects to
discontinue his employment with the Company, or his employment with the Company
is terminated for cause, as defined in that certain Employment Agreement between
Grantee and the Company dated June 6, 1988, then Grantee shall forfeit all
Installments of the Award for which a Vesting Date has not occurred as of the
date of termination as provided above.

                  (d) If, prior to any Vesting Date, the Company elects to
terminate Grantee's employment with the Company other than for cause as defined
in subparagraph (c) above, or Grantee dies or becomes totally disabled, then
Grantee (or his beneficiary, as stated below in the case of death) shall be
entitled to receive payment, as provided in this subparagraph (d), for the value
of all Installments for which a Commencement Date has occurred on or prior to
the date of termination, death or total disability, as applicable. The payment
for the value of such Installment(s) shall be made to Grantee within thirty (30)
days of the date of termination, death or disability, as applicable, shall be
solely in cash, with the value of such Installment(s) being the product of (i)
the number of shares for such Installment or Installments as set out in the
above table, and (ii) the closing price of the shares of Common Stock on the
NYSE on the date of termination, death or disability, as applicable, or, if such
date is not a day on which the NYSE is open for trading, the last business day
preceding such date when the NYSE is open for trading. Grantee may name a
beneficiary or beneficiaries to receive any payment which he would otherwise be
entitled to hereunder in the event of his death while in the employ of the
Company. Such designation shall be made on a form to be provided by and filed
with the Corporate Secretary of the Company. If Grantee fails to designate a
beneficiary or no designated beneficiary survives Grantee, such payment shall be
made to the legal representative of Grantee's estate. Grantee shall not be
entitled to receive payment under this subparagraph (d) for any Installment for
which a Commencement Date has not occurred as of the date of termination, death
or disability, as applicable.

                  (e) If, prior to any Vesting Date, an individual other than
Grantee or the current Chief Executive Officer of the Company, becomes the Chief
Executive Officer of the Company (which, for purposes of this subparagraph,
shall include any entity which comes to control the Company), then Grantee, upon
written request to the Company, is entitled to receive payment, as provided in
this subparagraph (e), for the value of all Installments for which a
Commencement Date has occurred on or prior to the date of the written request
The payment for such Installment(s) shall be made to Grantee within thirty (30)
days of receipt of Grantee's notice, shall be solely in cash, with the value of
such Installment(s) being the product of (i) the number of shares for such
Installment or Installments as set out in the above table, and (ii) the closing
price of the shares of Common Stock on the NYSE on the date of such written
request or if such date is not a day on which the NYSE is open for trading, the
last business day preceding such date when the NYSE is open for trading.

                  RESTRICTIONS CONTAINED IN A CONDITIONAL STOCK GRANT AGREEMENT
                  DATED AS OF DECEMBER 17, 1998, BY AND BETWEEN APACHE

to execute a blank stock power with respect to the stock certificate
representing the share portion of any Installment.

         6.       ADJUSTMENTS.

                  (a) If the Company shall at any time increase or decrease the
number of its outstanding shares of Common Stock or change in any way the rights
and privileges of such shares by means of a stock dividend or any other
distribution upon such shares payable in shares of Common Stock, or through a
stock split, subdivision, consolidation, combination, reclassification or
recapitalization involving the outstanding shares of Common Stock (hereinafter a
"capital restructuring"), then upon the occurrence of a capital restructuring,
the number of shares of Common Stock of each unvested Installment shall be
appropriately increased, decreased or changed in like manner as if the number of
shares of Common Stock of each unvested Installment had been issued,
outstanding, fully paid and non-assessable at the record date for the capital
restructuring.

                  (b) In the event that the Company is merged or consolidated
with another corporation and the Company is not the surviving corporation, or if
all or substantially all of the assets or more than 50 percent of the
outstanding shares of Common Stock of the Company is acquired by any other
corporation, business entity or person, or in case of a reorganization (other
than a reorganization under the United States Bankruptcy Code) or liquidation of
the Company, and if the provisions of subparagraph (c) hereof do not apply, the
Board of Directors, or the board of directors of any corporation assuming the
obligations of the Company, shall either (i) make appropriate provision for the
adoption and continuation of this Agreement by the acquiring or successor
corporation and for the protection of Grantee by the substitution on an
equitable basis of appropriate stock of the Company or of the merged,
consolidated or otherwise reorganized corporation which will be issuable with
respect to any outstanding Installment, provided that no additional benefits
shall be conferred upon Grantee as a result of such substitution, or (ii) upon
written notice to Grantee, the Board of Directors, in its sole discretion, if it
so elects, may accelerate the vesting of any unvested Installment so that all
unvested Installments are fully vested and payable prior to any such event.

                  (c) In the event of a change in control of the Company as
defined below, then the Board of Directors may, in its sole discretion, if it so
elects, take any of the following actions: (i) accelerate the vesting of the
unvested Installments so that the unvested Installments become fully vested and
payable, which acceleration may be conditional upon the occurrence of subsequent
events including, without limitation, a change in control, and may be made
irrevocable, either conditionally or unconditionally; and (ii) make any other
adjustments or amendments to the unvested Installments as the Board of Directors
deems appropriate.

                  (d) For purposes of this Agreement, a "change in control"
shall mean any of the events specified in the Company's Income Continuance Plan
or any successor plan which constitute a change in control within the meaning of
such plan.
