                              CALLAWAY GOLF COMPANY
                            1991 STOCK INCENTIVE PLAN
                   (as Amended and Restated - August 15, 2000)

1.      PURPOSES OF THE PLAN

           The purposes of this Stock Incentive Plan ("Plan") of Callaway Golf
Company, a Delaware corporation (the "Company"), are to enable the Company to
attract, retain and motivate their officers, directors, key employees and
consultants with compensatory arrangements and benefits that make use of or are
measured by Company stock so as to provide for or increase the proprietary
interests of such persons in the Company or to align their interests with those
of the Company's shareholders.

2.      PLAN AWARDS

           To carry out the purposes of the Plan, the Company will from time to
time enter into various arrangements with persons eligible to participate
therein and confer various benefits upon them. The following such arrangements
or benefits are authorized under the Plan if their terms and conditions are not
inconsistent with the provisions of the Plan: Stock Options, Restricted Stock,
Sales of Securities, Stock Bonuses, Performance Shares, Performance Units, Stock
Appreciation Rights, Phantom Stock, Dividend Equivalents and Other Stock-Based
Benefits. Such arrangements and benefits pursuant to the Plan are sometimes
herein referred to as "Awards." The authorized categories of benefits for which
Awards may be granted are defined as follows:

           Stock Options: A Stock Option is a right granted under the Plan to
purchase a specified number of shares of Common Stock at such exercise price, at
such times, and on such other terms and conditions as are specified in the
Award. A Stock Option may but need not (a) provide for the payment of some or
all of the option exercise price in cash or by promissory note or by delivery of
previously owned shares (including the technique known as "pyramiding") or other
property or by withholding some of the shares which are being purchased; (b)
include arrangements to facilitate the grantee's ability to borrow funds for
payment of the exercise price; or (c) be an Incentive Stock Option.

           Restricted Stock: Restricted Stock is Common Stock sold under the
Plan (other than through the exercise of a Stock Option) at a substantial
discount from its Fair Market Value or at its par value, but subject during
specified periods of time to such restrictions on its transferability and
repurchase rights as are expressed in the Award and as may constitute a
substantial condition of forfeiture while in effect.

           Sales of Securities: A Sale of Securities is a sale under the Plan of
unrestricted shares of Common Stock or of debt or other securities which are
convertible into shares of Common Stock upon such terms and conditions as may be
established in the terms of the Award.

           Stock Bonuses: A Stock Bonus is the issuance or delivery of
unrestricted or restricted shares of Common Stock under the Plan as a bonus for
services rendered or for any other valid consideration under applicable law.

           Performance Shares: A Performance Share is an Award that represents a
fixed number of shares of Common Stock which vests at a specified time or over a
period of time in accordance with performance criteria established in connection
with the granting of the Award. Such criteria may measure the performance of the
grantee, of the business unit in which the grantee is employed, or of the
Company, or a combination of any of the foregoing. The vested portion of the
Award is payable to the grantee either in the shares it represents or in cash in
an amount equal to the Fair Market Value of those shares on the date of vesting,
or a combination thereof, as specified in the

<PAGE>

Award.

           Performance Units: A Performance Unit is an Award that represents a
fixed amount of cash which vests at a specified time or over a period of time in
accordance with performance criteria established in connection with the granting
of the Award. Such criteria may measure the performance of the grantee, of the
business unit in which the grantee is employed, or of the Company or a
combination of any of the foregoing. The vested portion of the Award is payable
to the grantee either in cash or in shares valued at their Fair Market Value on
the date of vesting, or a combination thereof, as specified in the Award.

           Stock Appreciation Rights: A Stock Appreciation Right is a right
granted under the Plan to receive a payment that is measured with reference to
the amount by which the Fair Market Value of a specified number of shares of
Common Stock appreciates from a specified date, such as the date of grant of the
Award, to the date of exercise. Payment of a Stock Appreciation Right may be
made in cash or in shares valued at their Fair Market Value on the date of
exercise, or combination thereof, as specified in the Award. A Stock
Appreciation Right may but need not be granted in tandem with a Stock Option and
require the surrender of that Stock Option or a portion thereof in connection
with the exercise of the Stock Appreciation Right.

           Phantom Stock: Phantom Stock is a cash bonus granted under the Plan
measured by the Fair Market Value of a specified number of shares of Common
Stock on a specified date, or measured by the excess of such Fair Market Value
over a specified minimum, which may but need not include a Dividend Equivalent.

           Dividend Equivalents: A Dividend Equivalent is a right granted under
the Plan to receive an amount in cash equivalent to the dividends that are paid,
if any, on a specified number of shares of Common Stock during a certain period
of time.

           Other Stock-Based Benefits: An Other Stock-Based Benefit is any
arrangement granted under the Plan not otherwise described above which (a) by
its terms might involve the issuance or sale of Common Stock or (b) involves a
benefit that is measured, in whole or in part, by the value, appreciation,
dividend yield or other features attributable to a specified number of shares of
Common Stock.

           An Award may consist of one such arrangement or benefit or two or
more of them in tandem or in the alternative. Subject to the provisions of the
Plan, any Award granted pursuant to the Plan may contain such additional terms
and provisions as those administering the Plan for the Company may consider
appropriate. Among other things, any such Award may but need not also provide
for (i) the satisfaction of any applicable tax withholding obligation by the
retention of shares to which the grantee would otherwise be entitled or by the
grantee's delivery of previously owned shares or other property and (ii)
acceleration of vesting, lapse of restrictions, cash settlement or other
adjustment to the terms of the Award in the event of a merger, sale of assets or
change of control of the Company.

3.      STOCK SUBJECT TO THE PLAN

           The kind and maximum number of shares of stock that may be sold or
issued under the Plan, whether upon exercise of Stock Options or in settlement
of other Awards, shall be 10,000,000 shares of Common Stock (this number
reflects all stock splits through August 15, 2000, and is subject to further
adjustments set forth hereinbelow). If the outstanding shares of stock of the
class then subject to the Plan are increased or decreased, or are changed into
or are exchanged for a different number or kind of shares or securities or other
forms of consideration, as a result of one or more recapitalizations,
restructurings, reclassifications, stock splits, reverse stock splits, stock
dividends or the like, appropriate adjustments shall be made in the number
and/or kind of shares or securities or other forms of consideration which may
thereafter be sold or issued under the Plan and for which Awards (including
Incentive Stock Options) may thereafter be granted and for which outstanding
Awards previously granted under the Plan may thereafter be exercised or settled.

           If, on or before termination of the Plan, any shares of Common Stock
subject to an Award shall not be issued or transferred and shall cease to be
issuable or transferable for any reason, or if such shares shall have been
reacquired by the Company pursuant to restrictions imposed on such shares under
the Plan or the terms of an Award,

<PAGE>

the shares not so issued or transferred and the shares so reacquired shall no
longer be charged against the limitation provided for in this Section 3 and may
be again made the subject of Awards under this Plan. The shares of stock sold or
issued under the Plan may be obtained from the Company's authorized but unissued
shares, from reacquired or treasury shares, or from outstanding shares acquired
in the market or from private sources.

4.      ADMINISTRATION OF THE PLAN

           (a) The Plan shall be administered by the Board of Directors of the
Company (the "Board') or, in the discretion of the Board, a committee appointed
thereby (the "Committee '). Subject to the provisions of the Plan, the Board, or
the Committee, shall have full and final authority in its discretion to select
the eligible persons to whom Awards shall be granted hereunder, to grant such
Awards, to determine the terms and provisions of such Awards and the number of
shares to be sold or issued pursuant thereto. The Board (and the Committee)
shall also be empowered with full and final authority to adopt, amend, and
rescind such rules and regulations as, in its opinion, may be advisable in the
administration of the Plan. The Board or the Committee, as the case may be, may
delegate to Company officers or others in authority with respect to any Awards
that may be granted to Employees who are not then officers of the Company or
subject to Section 16 of the 1934 Act, subject to applicable legal requirements.
The interpretation and construction by the Board or the Committee of any term or
provision of the Plan or of any Award granted thereunder shall be final and
binding upon all participants in the Plan.

           (b) Pursuant to the authority described above, the Board or the
Committee may adopt such amendments to, and rules and regulations governing, the
Plan as may be considered advisable for purposes of compliance with applicable
federal or state securities laws. The Board of Directors has established the
following rules applicable to all Awards made pursuant to the Plan: No Award
granted hereunder (other than an Award expressly granting unrestricted shares)
may be transferred by the grantee except (i) by will or the laws of descent and
distribution, (ii) upon dissolution of marriage pursuant to a qualified domestic
relations order or division of community or marital property or (iii) with the
express written approval of the Board or Committee in its sole discretion. No
such permitted transfer shall, by itself, affect any vesting restrictions which
then apply to the Award. Persons who are subject to Section 16 of the 1934 Act
are also subject to the restrictions on transferability set forth in Section
7(a) of the Plan.

           (c) The Company may assist any person to whom an Award is granted
hereunder (including any officer or eligible director of the Company) in the
payment of the purchase price or other amounts payable in connection with the
receipt or exercise of that Award, by lending such amounts to such person on
such terms and at such rates of interest and upon such security (if any) as
shall be approved by the Board or the Committee.

5.      PERSONS ELIGIBLE TO PARTICIPATE

           Directors, officers and key employees of the Company shall be
eligible for the grant of Awards under the Plan at the discretion of the Board
or Committee provided -that no director of the Company who is not also an
employee of the Company shall be eligible to receive any Award hereunder.
Non-employee consultants to the Company who are deemed by the Board or Committee
to be of such significance to the Company that Awards hereunder are appropriate
in the interest of the Company shall also be eligible on ad hoc basis for the
grant of Awards hereunder.

6.      PLAN EFFECTIVENESS AND DURATION

           The Plan shall become effective as of the date designated by the
Board, and shall continue (unless earlier terminated by the Board) until its
expiration as set forth below; provided that this Plan shall be submitted for
the approval of each class of capital stock eligible to vote on matters
submitted to a vote of the Company's shareholders as soon as reasonably
practicable; and provided further that any Awards granted prior to such
shareholder approval shall be considered subject to such approval. Unless
previously terminated, the Plan will expire ten years after its effective date,
but such expiration shall not affect any Award previously made or granted which
is then outstanding.

<PAGE>

7.      SECTION 16 PERSONS

           Notwithstanding any other provision herein, any Award granted
hereunder to an officer or director of the Company who is then subject to
Section 16 of the 1934 Act shall be subject to the following limitations:

           (a) The Award may provide for the issuance of shares of Common Stock
as a Stock Bonus for no consideration other than services rendered. In the event
of an Award under which shares of Common Stock are or may in the future be
issued for any other type of consideration, the amount of such consideration
shall either (i) be equal to the amount required to be received by the Company
in order to assure compliance with applicable state law or (ii) be equal to or
greater than 50% of the Fair Market Value of such shares on the date of grant of
such Award.

           (b) Any derivative security (as defined in the rules and regulations
of the Securities and Exchange Commission with respect to Section 16 of the 1934
Act) granted under this Plan shall be transferable by the recipient thereof only
to the extent such transfer is not prohibited by Rule 16b-3 under Section 16 of
the 1934 Act, by any other provision of this Plan or by any rule or regulation,
adopted by the Board or Committee pursuant to the Plan.

8.      AMENDMENT AND TERMINATION

           The Board may amend, suspend or terminate the Plan, provided that no
amendment of the Plan may, unless approved by the shareholders of the Company,
increase the maximum number of shares that may be made subject to sale or
issuance or may be sold or issued under the Plan, or alter the class of persons
eligible to participate in the Plan. The Board may in its discretion determine,
with respect to any amendments of the Plan (whether or not requiring shareholder
approval under this Plan or applicable law), that such amendments shall become
effective upon approval by the shareholders of the Company.

9.      CERTAIN DEFINITIONS

           The authorized categories of benefits for which Awards may be granted
under this Plan are defined in Section 2 above. In addition, the following terms
used in this Plan shall have the following meanings:

           "Common Stock" is the Company's common stock, as constituted on the
effective date of this Plan, and as thereafter adjusted as a result of any one
or more events requiring adjustment of outstanding Awards under Section 3 above.

           "Fair Market Value" of shares of stock shall be calculated (a) during
such time as the Company is not a publicly-traded company, by the Board based on
its good faith determination, and (b) at such times as the Company is
publicly-traded, on the basis of the closing price of stock of that class on the
day in question (or, if such day is not a trading day in the U.S. securities
markets, on the nearest preceding trading day), as reported with respect to the
principal market (or the composite of the markets, if more than one) in which
such shares are then traded; or, if no such closing prices are reported, on the
basis of the mean between the high bid and low asked prices that day on the
principal market or national quotation system on which such shares are then
quoted; or, if not so quoted, as furnished by a professional securities dealer
making a market in such shares selected by the Board or the Committee; or if no
such dealer is available, then the Fair Market Value shall be determined in good
faith by the Board.

           An "Incentive Stock Option" is a Stock Option that qualifies as an
"incentive stock option" as defined under Section 422 (or any applicable
successor provisions) of the Internal Revenue Code and that includes an express
provision that it is intended to be an Incentive Stock Option.

           A "Person" shall mean any individual, firm, partnership, corporation,
trust, estate, association, group (as such term is used in Rule 13d-5 under the
1934 Act) or other entity, and shall include any successor (by merger or
otherwise) to such entity.

           A "Subsidiary" of the Company is any corporation, partnership or
other entity in which the Company directly or indirectly owns 50% or more of the
total combined power to cast votes in the election of directors, trustees,
managing partners or similar officials.
