                    AMENDED BY THE DIRECTORS ON JANUARY 22, 
                    1998 (APPROVED BY THE INLAND REVENUE ON

                   ----------------------------------------- 



 
                           ARTHUR J. GALLAGHER & CO.
                                 UNITED KINGDOM
                     INCENTIVE STOCK OPTION PLAN (the Plan)

1.   Purpose

     The Plan has been established to enable the United Kingdom resident
     employees and directors of Arthur J. Gallagher & Co. (the Company) and
     companies in its group to obtain beneficial tax treatment under section 185
     of the Income and Corporation Taxes Act 1988 (Section 185) in respect of
     options granted to them over shares in the capital of the Company.

     The Plan shall be administered by the Committee of the Board of the Company
     appointed to administer the Arthur J. Gallagher & Co. Incentive Stock
     Option Plan (the US Plan) pursuant to the powers conferred on the Committee
     under the US Plan. The Plan accordingly reflects the terms and conditions
     of the US Plan and, for administrative convenience only, the rules of the
     Plan show in italics those provisions which are not contained in the US
     Plan.

     The Plan was approved by the Inland Revenue pursuant to Schedule 10 to the
     Finance Act 1984 (Schedule 10) on 28 May 1986.

     The purpose of the Plan is to promote the interests of Arthur J. Gallagher
     & Co., a Delaware corporation, and its shareholders by providing key
     employees resident in the United Kingdom on whom rests the major
     responsibility for the present and future success of the Company and its
     subsidiaries with an opportunity to acquire a proprietary interest in the
     Company and thereby develop a stronger incentive to put forth maximum
     effort for the continued success and growth of the Company and its
     subsidiaries. These goals are enhanced further by the fact that
     participants in the Plan who are subject to United Kingdom tax will be
     entitled to the beneficial tax treatment provided for in section 185 in
     respect of options granted to and exercised by them in accordance with the
     rules of the Plan and the provisions of section 185. In addition, the
     opportunity to acquire a proprietary interest in the Company will aid in
     attracting and retaining key personnel of outstanding ability.

2.   Administration

     All administrative duties hereunder shall rest with the Option Committee of
     the Board of Directors (hereinafter the Committee) which will consist of
     not less than two persons, each of whom will be a disinterested person as
     that term is used in Rule 16b-3 under the Securities Exchange Act 1934, as
     amended. The Committee shall have the duty and authority, subject to the
     provisions of the Plan and of Schedule 9 to the Income and Corporation
     Taxes Act 1988 (Schedule 9), to:

     (a)  determine which individuals shall receive options and how many options
          each individual shall receive;

                                       2

 
     (b)  grant the options;

     (c) at the time of a grant of options determine the terms and conditions of
     the options including exercise dates, limitations on exercise, and time
     periods for exercise, (Vesting Schedules) and the price and payment terms;

     (d) prescribe the form or forms of the instruments evidencing any options
     granted under the Plan and of any other instruments required under the
     Plan, and to change such forms from time to time; and

     (e) adopt such rules and regulations for the administration of the Plan as
     it deems appropriate.

     In making the foregoing determinations the Committee may take into account
     the nature of the services rendered by the respective individuals, their
     present and potential contributions to the Company's success, and such
     other factors as the Committee, in its discretion, shall deem relevant.

3.   Shares Subject to the Plan

     The shares that may be made subject to options under the Plan shall be
     shares of Common Stock of the Company, one dollar ($1.00) par value (Common
     Stock), and the total shares subject to option and issued pursuant to this
     Plan shall not exceed, in the aggregate, 720,000 share of the Common Stock
     of the Company. If any such option lapses or terminates for any reason
     without having been exercised in full, the shares covered by the
     unexercised portion of such option may again be made subject to options
     granted under the Plan. Shares issued upon exercise of options granted
     under the Plan may be shares held by the Company either as treasury shares
     or as authorized but previously unissued shares.

     The shares put under option pursuant to the Plan shall comply with the
     conditions contained in paragraphs 10 to 14 of Schedule 9.

4.   Eligibility

     Employees eligible to participate in the Plan shall be those salaried
     officers and other salaried key employees of the Company and its
     subsidiaries who, in the opinion of the Committee, are in a position to
     affect materially the profitability and growth of the Company and its
     subsidiaries. Directors who are salaried key employees within the meaning
     of the foregoing are eligible to participate in the Plan, provided however
     that members of the Committee shall not be eligible to receive options. An
     employee owning stock comprising over 10% of the combined voting power of
     the Company or any subsidiary (a 10% Shareholder) is not eligible to
     receive an option unless the option price offered is at least 110% of the
     fair market value of the stock at the time the option is granted, and
     unless the option by its terms expires not more than five years from the
     date of grant. For all purposes of the Plan, except where "wholly owned" is
     indicated, the term subsidiary shall mean a corporation 50% or more of the
     stock of which is owned directly

                                       3

 
     by the Company or indirectly through another corporation or corporations in
     which the Company owns 50% or more of the stock and which is, in addition,
     under the control of the Company, within the meaning of section 840 of the
     Income and Corporation Taxes Act 1988.

     Further, an option may only be granted under the Plan to a person if (and
     only if) he is a full-time executive director or qualifying employee of the
     Company and he does not fall within the provisions of paragraph 8 of
     Schedule 9.

     For the purpose of this paragraph a person shall be treated as a full-time
     executive director of the Company if he is employed by the Company or a
     subsidiary to work not less than 25 hours per week (excluding meal breaks).

     For the purpose of this paragraph a qualifying employee is an employee of
     the Company or a subsidiary who is not also a director of the Company or a
     subsidiary and who is required to work for that company under a contract of
     employment.

5.   Granting of Options

     Subject to the terms and conditions of the Plan, the Committee may from
     time to time prior to the termination of the Plan grant to eligible
     employees options to purchase the number of shares of Common Stock
     authorized by the Committee, subject to such terms and conditions as the
     Committee may determine. More than one option may be granted to the same
     employee. The day on which the Committee approves the granting of an option
     shall be considered as the date on which such option is granted.

6.   Option Price

     The purchase price per share of Common Stock subject to an option shall be
     fixed by the Committee, but shall not be less than 100% (110% in the case
     of a 10% Shareholder) of the fair market value of a share of Common Stock
     on the date the option is granted by the Committee. The fair market value
     of a share of Common Stock shall be the closing price for the Company's
     Common Stock on the New York Stock Exchange as listed in the Wall Street
     Journal for the date the option is granted.

7.   Terms of Options

     The term of each option shall be not more than 10 years commencing with the
     date of grant (5 years in the case of a 10% Shareholder). Each option shall
     also terminate as provided in paragraph 13.

8.   Method of Exercising Options

     Any option granted hereunder may be exercised by the optionee by delivering
     to the Company at is main office (attention of the Secretary) written
     notice of the number of shares with respect to which the option rights are
     being exercised and by paying in cash

                                       4

 
     the purchase price of the shares purchased in full, in exchange for the
     issuance and delivery of certificates therefor.

9.   Amount Exercisable

     Each option may be exercised, so long as it is valid and outstanding, from
     time to time in part or as a whole, subject to any limitations with respect
     to the number of shares for which the option may be exercised at a
     particular time and to such other conditions as the Committee in its
     discretion may specify upon granting the option, provided that any such
     conditions have been approved by the Inland Revenue prior to their
     imposition; and provided, however, that the partial exercise of an option
     or a combination of options shall in no event be for the smaller of (a) 100
     shares of Common Stock, or (b) 10 per cent of the shares of Common Stock
     subject to options held by the employee, unless a purchase of fewer shares
     would entirely exhaust the options held by the employee; and provided
     further that the optionee's cumulative purchases of Common Stock subject to
     this option may not exceed the following:




                                                    Percentage of
                                                     Common Stock          Percentage of
                                                  Subject to Option        Common Stock
               Years Following                       (Other than         Subject to Option
                Date of Grant                      10% Shareholder)      (10% Shareholder)
                                                                          
          remainder of calendar year                       0%                    0%
           following date of grant

      1/st/ calendar year following date                  10%                   20%

     10/th/ calendar year following date       100%                100%
             of grant

     and provided further that the Committee shall not attach conditions to the
     exercise of the option which would prevent the employee from being capable
     of satisfying the requirements of sub-section (5) of Section 185 at some
     time during the life of the option. Notwithstanding the provisions of this
     Paragraph 9, no option granted under the Plan shall be exercised at any
     time when the employee holding that option falls within the provisions of
     Paragraph 8 of Schedule 9.

     On the exercise or partial exercise of an option the shares will be
     allotted to the employee, a share certificate issued and his name
     registered as stockholder in the Company's books within the thirty days
     following the date of exercise of the option.

10.  Maximum Annual Amount

     No option shall be granted to an employee under the Plan if the aggregate
     market value (determined as in paragraph 6 above) of all shares of Common
     Stock the subject of outstanding options granted to him under the Plan, or
     granted to him under any other share option scheme approved under Schedule
     9 and established by the Company or an associated company would exceed
     (Pounds)30,000, or if different, such appropriate limit as shall from time
     to time apply to the Plan by virtue of paragraph 28 of Schedule 9.

     In order to calculate whether the aggregate fair market value of all shares
     of Common Stock the subject of any option (determined as in paragraph 6
     above) exceeds the limit referred to in this paragraph, the UK pounds
     sterling equivalent of such aggregate fair market value shall be calculated
     by applying the US$/UK(Pounds) spot exchange rate quoted in the London
     Financial Times on the date on which the relevant option was granted.

     For the purpose of this paragraph:

          associated company shall mean an associated company within the meaning
          of section 840 of the Income and Corporation Taxes Act 1988.

11.  Capital Adjustments Affecting Common Stock

     In the event of a capital adjustment resulting from a stock dividend, stock
     split, reorganization, merger, consolidation, or a combination or exchange
     of shares, the number of shares of Common Stock subject to the Plan and the
     number of shares under the option shall be adjusted in a manner consistent
     with such capital adjustment. The price of any shares under option shall be
     adjusted so that there will be no change in the aggregate purchase price
     payable upon exercise of any such option.

     Provided that no adjustment consequent on such an event shall be made
     pursuant to this paragraph 11 in respect of options granted under the Plan
     at any time while the Plan is approved by the Inland Revenue without the
     prior approval of the Inland Revenue.

                                       6

 
12.  TRANSFERABILITY OF OPTIONS

     Options shall not be transferable by the optionee otherwise than by will or
     under the laws of descent and distribution, and shall be exercisable,
     during his lifetime, only by him. Provided that an option granted under the
     Plan shall only be transferable in the circumstances set out in paragraph
     27(2) of Schedule 9.

13.  /1/TERMINATION OF EMPLOYMENT OR DEATH OF OPTIONEE

     Any termination of the employment relationship between the Company or a
     subsidiary and the optionee due to death, disability or retirement, as
     those events are provided for in (A), (B) and (C) below, shall not act to
     terminate an option grant.  A termination of the employment relationship
     for any reason other than those so provided in (A), (B) and (C) below shall
     act to terminate an option grant as of the effective date of such
     termination of the employment relationship, as reflected in the records of
     the Company.  The Committee shall have the authority to determine whether
     an authorized leave of absence or absence due to military or government
     service shall constitute a termination of the employment relationship for
     purposes hereof.

     (A) /1/DEATH If an optionee dies while in the employ of the Company or a
     subsidiary and before the date of expiration of such option, such option
     shall terminate on the earlier of such date of expiration or twelve months
     following the date of such death and any Vesting Schedule shall be
     accelerated so that the option shall be exercisable as to 100% of the
     Common Stock subject to the Option (notwithstanding that the conditions as
     to cumulative purchases referred to in paragraph 9 above would not
     otherwise be satisfied).  After the death of the optionee, his executors,
     administrators, or any person or persons to whom his option may be
     transferred by will or by the laws of descent and distribution shall have
     the right, at any time prior to such termination, to exercise the option,
     in whole or in part, subject to the terms and conditions of the Plan and of
     the option grant letter or stock option agreement entered into by the
     optionee as varied by this paragraph (A).

     (B) /1/RETIREMENT FOR DISABILITY  If, before the date of expiration of the
     option, the employment relationship between the Company or any subsidiary
     and the optionee is terminated at a time when the optionees' medical
     condition, upon such termination, would qualify the optionee to receive
     long term disability benefits under the Company's employee benefits plan
     such option shall not terminate on the termination of the employment
     relationship and any Vesting Schedule shall be accelerated so that the
     option shall be exercisable at any time until the expiration of the option
     in respect of 100% of the Common Stock then remaining subject to the Option
     (notwithstanding that the conditions as to cumulative purchases referred to
     in paragraph 9 above would not otherwise be satisfied).

     --------------------------
     /1/ The provisions of Rule 13 were amended with effect from the date of
         Inland Revenue approval on 16 July 1996 and are therefore applicable
         only to options granted after that date.

                                       7

 
     (C) /1/RETIREMENT  If, before the date of expiration of the option, the 
     holder of an option retires from the employment of the company or any
     subsidiary in circumstances other than those referred to in paragraph (B)
     above at a time when the optionee, upon such termination, would be
     immediately eligible to commence to receive retirement benefits under the
     Company's pension plan such option shall not terminate on the termination
     of the employment relationship and any Vesting Schedule shall be
     accelerated so that the option shall be exercisable at any time until the
     expiration of the option in respect of 100% of the Common Stock then
     remaining subject to the Option (notwithstanding that the conditions as to
     cumulative purchases referred to in paragraph 9 above would not otherwise
     be satisfied).

14.  REQUIREMENTS OF LAW

     In the event the shares issuable on exercise of an option are not
     registered under the Securities Act of 1933 of the USA, the Company shall
     imprint the following legend or any other legend which counsel for the
     Company considers necessary or advisable to comply with the Securities Act
     of 1933:

          "The shares of stock represented by this certificate have not been
          registered under the Securities Act of 1933 or under the securities
          laws of any State and may not be sold or transferred except upon such
          registration or upon receipt by the Corporation of an opinion of
          counsel in form and substance satisfactory to the Corporation that
          registration is not required for such sale or transfer."

     The Company may, but shall in no event be obligated to, register any
     securities covered hereby pursuant to the Securities Act of 1933 (as now in
     effect or as hereafter amended); and in the event an shares are so
     registered the Company may remove any legend on certificates representing
     such shares.  The Company shall make reasonable efforts to cause the
     exercise of an option or the issuance of shares pursuant thereto to comply
     with any law or regulation of any governmental authority.

15.  NO RIGHTS AS STOCKHOLDER

     No optionee shall have rights as a stockholder with respect to shares
     covered by his option until the date of issuance of a stock certificate for
     such shares; and, except as otherwise provided in paragraph 11 hereof, no
     adjustment for dividends, or otherwise, shall be made if the record date
     therefor is prior to the date of issuance of such certificate.

16.  EMPLOYMENT OBLIGATIONS

     The granting of any option shall not impose upon the Company or subsidiary
     any obligation to employ or continue to employ any optionee; and the right
     of the Company or 

- -----------------------
     /1/ The provisions of Rule 13 were amended with effect from the date of
         Inland Revenue approval on 16 July 1996 and are therefore applicable
         only to options granted after that date.

                                       8

 
     subsidiary to terminate the employment of any officer or other employee
     shall not be diminished or affected by reason of the fact that an option
     has been granted to him.

17.  WRITTEN AGREEMENT

     Each option granted hereunder shall be embodied in writing, the form and
     content of which shall be as the Committee in its discretion shall deem
     advisable.

18.  AMENDMENT, TERMINATION AND EFFECTIVE DATE

     This Plan shall be effective as of the date of its approval by the Inland
     Revenue and shall terminate on 29 May 2006.  The Board shall have the right
     to amend, suspend or terminate the Plan, provided that no termination or
     amendment of the Plan may, without the consent of the individual to whom
     any option shall have been therefore granted, adversely affect the rights
     of such individual under such option.  Unless in respect of (a), (b) and
     (c) below first approved by the shareholders of the Company, no amendment
     shall be made to the Plan which:

     (a)  materially modifies the eligibility requirements provided in paragraph
          4;

     (b)  changes the option price specified in Paragraph 6, except as provided
          in Paragraph 11; or

     (c)  changes the option period in Paragraph 7.

     Notwithstanding the provisions of this Paragraph 18, no amendment shall
     have effect at any time when the Plan is approved by the Inland Revenue
     until approved by the Inland Revenue.  However, the Committee may make such
     amendments as are required to obtain the approval by the Inland Revenue of
     the Plan pursuant to Schedule 9.

19.  CHANGE IN CONTROL

     In the event of a change in control of the Company, as defined below, each
     option outstanding shall immediately become exercisable in full.  For all
     purposes of the Plan, a "change in control of the Company" occurs if:

     (a)  any person or group, as defined in Sections 13(d) and 14(d)(2) of the
          Exchange Act, as amended, is or becomes the beneficial owner, directly
          or indirectly of securities of the Company representing 50 percent or
          more of the combined voting power of the Company's outstanding
          securities then entitled to vote for the election of directors; or

     (b)  during any period of two consecutive years, individuals who at the
          beginning of such period constitute the Board of Directors and any new
          directors whose election by the Board or nomination for election by
          the Company's Stockholders was approved by at least two-thirds of the
          directors then still in office who either were

                                       9

 
          directors at the beginning of the period or whose election was
          previously so approved cease for any reason to constitute at least a
          majority thereof; or
