                  WHEREAS, the Company has made available to the Purchaser, the

                  WHEREAS, this Agreement is one of several other agreements

managers and directors of the Company or one of its subsidiaries and Associated
Entities (collectively, the "OTHER MANAGEMENT AND EMPLOYEE SHAREHOLDERS").

                  NOW, THEREFORE, to implement the foregoing and in
consideration of the mutual agreements contained herein, the parties hereto
hereby agree as follows:


<PAGE>

1. PURCHASE AND SALE OF ORDINARY SHARES.

                  (a) PURCHASE OF ORDINARY SHARES. Subject to all of the terms
and conditions of this Agreement, the Purchaser hereby subscribes for and shall
purchase, and the Company shall issue and sell to the Purchaser, the Purchased
Shares at a purchase price equal to the Per Share Purchase Price at the Closing
provided for in Section 2(a) hereof. Notwithstanding anything in this Agreement
to the contrary, the Company shall have no obligation to issue and sell any
Ordinary Shares to (i) any person who will not be either an employee or a
manager or director of the Company or a direct or indirect subsidiary of the
Company or of an Associated Entity (and for this purpose with regard to
employees resident in the United Kingdom, the term "subsidiary" will have the
meaning given in Section 736 of the United Kingdom Companies Act 1985)
immediately following the Closing or (ii) any person who is a resident of a
jurisdiction in which the sale of Ordinary Shares to such person would
constitute a violation of the securities, "blue sky" or other laws of such
jurisdiction.

                  (b) CONSIDERATION. Subject to all of the terms and conditions
of this Agreement, the Purchaser shall deliver to the Company at the Closing (by
means of either an official bank check, a check drawn on a London clearing bank
or an electronic funds transfer), in pounds sterling, in an amount equal to the
Subscription Price set forth on Annex A hereto.

                  (c) EXECUTION OF DOCUMENTS. Notwithstanding anything to the
contrary in this Section 1, the Company shall not have any obligation to issue
any Purchased Shares unless and until the Company is satisfied, in its sole
discretion, that (i) the Purchaser has duly executed and delivered this
Agreement and (ii) payment of the Subscription Price is made in accordance with
the provisions of Section 1(b) above.

2. CLOSING.

                  (a) TIME AND PLACE. Except as otherwise mutually agreed by the
Company and the Purchaser, the closing (the "CLOSING") of the transaction
contemplated by this Agreement shall be held at the offices of the Company
Secretary, Ten Trinity Square, London EC3P 3AX, England on or about December 20,
1999 (the "CLOSING DATE").

                  (b) CLOSING. At the Closing, (I) the Company shall deliver to
the Trinity Trustee a stock certificate registered in the Purchaser's name and
representing the number of Purchased Shares subscribed for pursuant hereto,
which certificate shall bear the legends set forth in Section 3(b) (which
certificate will be held by the Trinity Trustee until the Purchaser no longer
has an actual or contingent obligation to transfer Purchased Shares under this
Agreement or any agreement referred to in this Agreement; the Trinity Trustee
will deliver the certificate to the Company on behalf of the Purchaser when the
Purchaser is required to do so under this Agreement or any agreement referred to
in this Agreement), and (II) the Purchaser shall deliver to the Company (by
means of either an official bank check, a check drawn on a London clearing bank
or an electronic funds transfer), in pounds sterling, in an amount equal to the
Subscription Price set forth on Annex A hereto.

3. PURCHASER'S REPRESENTATIONS, WARRANTIES AND COVENANTS.

                  (a) The Purchaser agrees and acknowledges that the Purchaser
will not, directly or indirectly, offer, transfer, sell, assign, pledge,
hypothecate or otherwise dispose of (any such act being referred to herein as a
"TRANSFER") any Purchased Shares or, at the time of exercise, the Ordinary
Shares issuable upon exercise of the Options (the "OPTION SHARES" and,
collectively with the Purchased Shares, the "SHARES") unless such transfer
complies with Section 4 of this Agreement. If the Purchaser is an "AFFILIATE"
(as defined under Rule 405 of the rules and regulations promulgated under the
Act (as defined below) and as interpreted by the Board of Directors of the
Company (the "BOARD")) of the Company (an "AFFILIATE"), the Purchaser also
agrees and acknowledges that the Purchaser will not transfer any Shares unless:

                  (i) the transfer is pursuant to an effective registration
         statement under the Securities Act of 1933, as amended, and the rules
         and regulations in effect thereunder (the "ACT"), and in compliance
         with applicable provisions of U.S. state securities laws, OR

                  (ii) (A) counsel for the Purchaser (which counsel shall be
         reasonably acceptable to the Company) shall have furnished the Company
         with an opinion, satisfactory in form and substance to the Company,
         that no such registration is required because of the availability of an
         exemption from registration under the Act and (B) if the Purchaser is a
         citizen or resident of any country other than the United States, or the
         Purchaser desires to effect any transfer in any such country, counsel
         for the Purchaser (which counsel shall be reasonably satisfactory to
         the Company) shall have furnished the Company with an opinion or other
         advice reasonably satisfactory in form and substance to the Company to
         the effect that such transfer will comply with the securities laws of
         such jurisdiction.

Notwithstanding the foregoing, the Company acknowledges and agrees that any of
the following transfers are deemed to be in compliance with the Act and this
Agreement and no opinion of counsel is required in connection therewith: (x) a
transfer made pursuant to Section 5, 6 or 7 hereof, (y) a transfer upon the
death of the Purchaser to his or her executors, administrators, testamentary
trustees, legatees or beneficiaries (the "PURCHASER'S ESTATE") or a transfer to
the executors, administrators, testamentary trustees, legatees or beneficiaries
of a person who has become a holder of Shares in accordance with the terms of
this Agreement, provided that it is expressly understood that any such
transferee shall be bound by the provisions of this Agreement and the transferee
agrees in writing to be bound by the terms and conditions hereof and (z) a
transfer made after the Closing Date in compliance with the U.S. federal
securities laws and the securities laws of any other applicable jurisdiction to
a trust or custodianship the beneficiaries of which may include only the
Purchaser, his or her spouse or his or her lineal descendants (including
children by adoption and step children) (a "PURCHASER'S TRUST"), provided that
such transfer is made expressly subject to this Agreement and that the
transferee agrees in writing to be bound by the terms and conditions hereof.

                  (b) The certificate (or certificates) representing the
Shares shall bear the following legends:


                                       3

<PAGE>


                  "THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE
                  TRANSFERRED, SOLD, ASSIGNED, PLEDGED, HYPOTHECATED OR
                  OTHERWISE DISPOSED OF UNLESS SUCH TRANSFER, SALE, ASSIGNMENT,
                  PLEDGE, HYPOTHECATION OR OTHER DISPOSITION COMPLIES WITH THE
                  PROVISIONS OF THE MANAGEMENT AND EMPLOYEE SHAREHOLDERS' AND
                  SUBSCRIPTION AGREEMENT DATED AS OF DECEMBER 20, 1999 AMONG TA
                  I LIMITED (THE "COMPANY"), MOURANT & CO. TRUSTEES LIMITED, THE
                  TRUSTEE OF A TRUST ORGANIZED BY THE COMPANY, AND THE PURCHASER
                  NAMED ON THE FACE HEREOF AND THE MEMORANDUM AND ARTICLES OF
                  ASSOCIATION OF THE COMPANY (COPIES OF WHICH ARE ON FILE WITH
                  THE SECRETARY OF THE COMPANY)."

                  and, for Georgia residents:

                  "THE SHARES HAVE BEEN ISSUED OR SOLD IN RELIANCE ON PARAGRAPH
                  (13) OF CODE SECTION 10-5-9 OF THE "GEORGIA SECURITIES ACT OF
                  1973," AND MAY NOT BE SOLD OR TRANSFERRED EXCEPT IN A
                  TRANSACTION WHICH IS EXEMPT UNDER SUCH ACT OR PURSUANT TO AN
                  EFFECTIVE REGISTRATION UNDER SUCH ACT."

                  and, for any offering of sale in Italy:

                  "THE SHARES MAY BE NOT OFFERED, SOLD OR DELIVERED IN THE
                  REPUBLIC OF ITALY UNLESS THE OFFER IS IN COMPLIANCE WITH THE
                  REQUIREMENTS OF LAW NO. 216 OF 7 JUNE 1974, AS AMENDED, OR
                  ARTICLE 94 AND ONWARDS OF LEGISLATIVE DECREE NO. 58 OF 24
                  FEBRUARY 1998, ITS FULL IMPLEMENTATION. IN PARTICULAR, THE
                  SHARES SHOULD BE OFFERED EXCLUSIVELY THROUGH PRIVATE PLACEMENT
                  IN ITALY AND MAY NOT BE OFFERED OR SOLD OR RESOLD TO THE
                  PUBLIC IN ITALY IN CIRCUMSTANCES WHICH WOULD QUALIFY SUCH
                  OFFER OR SALE AS A PUBLIC OFFER AS DEFINED UNDER ITALIAN LAW."

                  (c) The Purchaser acknowledges that the Purchaser has been
advised that: (i) a restrictive legend in the form heretofore set forth shall be
placed on the certificates representing the Shares and (ii) a notation shall be
made in the appropriate records of the Company indicating that the Shares are
subject to restrictions on transfer and appropriate stop-transfer restrictions
will be issued to the Company's transfer agent with respect to the Shares. If
the Purchaser is an Affiliate, the Purchaser also acknowledges that (1) the
Shares must be held indefinitely and the Purchaser must continue to bear the
economic risk of the investment in the Shares unless they are subsequently
registered under the Act or an exemption from such registration is available,
(2) when and if Shares may be disposed of without registration in reliance on
Rule 144 of the rules and regulations promulgated under the Act, such
disposition can be made only in limited amounts in accordance with the terms and
conditions of such Rule and (3) if the Rule 144 exemption is not available,
public sale without registration will require compliance with some


                                       4

<PAGE>

other exemption under the Act. The Company acknowledges that a Purchaser who is
resident outside the United States may, subject to applicable law and the
restrictions on transfer set forth herein and in the Articles of Association of
the Company (the "ARTICLES"), transfer Shares outside the United States in
accordance with Regulation S under the Act.

                  (d) If any Shares are to be transferred in accordance with
Rule 144 or Regulation S under the Act or otherwise, the Purchaser shall
promptly notify the Company of such intended transfer and shall deliver to the
Company at or prior to the time of such transfer such documentation as the
Company may reasonably request in connection with such transfer and, in the case
of a transfer pursuant to Rule 144, shall deliver to the Company an executed
copy of any notice on Form 144 (or any successor form) required to be filed with
the Securities and Exchange Commission (the "SEC").

                  (e) The Purchaser agrees that, if any voting or non-voting
ordinary shares of the Company (together, the "COMMON SHARES") are offered to
the public pursuant to an effective registration statement under the Act (other
than registration of securities issued under an employee plan) and/or pursuant
to a floatation on the London Stock Exchange or other underwritten offering
outside the United States, the Purchaser will not effect any public sale or
distribution of any Ordinary Shares not covered by such registration statement
from the time of the receipt of a notice from the Company that the Company has
filed or imminently intends to file such registration statement or to commence
such floatation to, or within 180 days after, the effective date of such
registration statement or the completion of such floatation, unless otherwise
agreed to in writing by the Company.

                  (f) The Purchaser represents and warrants that (i) the
Purchaser has received and reviewed (a) the prospectus relating to the offer by
Willis Corroon Corporation to exchange all of its 9% Senior Subordinated Notes
due 2009 for its 9% Senior Subordinated Notes due 2009 that have been registered
under the Securities Act of 1933, (b) the 1998 year-end accounts of TA I
Limited, (c) the June 30, 1999 six-month accounts of TA I Limited, (d) the
Articles, (e) the Option Plan, (f) the Share Option Agreement, (g) the Sale
Participation Agreement, (h) the Registration Rights Agreement and (i) this
Agreement, certain of which documents set forth the rights, preferences, and
restrictions relating to the Shares, (ii) the Purchaser has been given the
opportunity to obtain any additional information or documents and to ask
questions and receive answers about such information, the Company and its
subsidiaries and Associated Entities and the business and prospects of the
Company and its subsidiaries and Associated Entities which the Purchaser deems
necessary to evaluate the merits and risks related to the Purchaser's investment
in the Shares and to verify the information received as indicated in this
Section 3(f), and he or she has relied solely on such information.

                  (g) The Purchaser further represents and warrants that (i) the
Purchaser's financial condition is such that the Purchaser can afford to bear
the economic risk of holding the Shares for an indefinite period of time and has
adequate means for providing for the Purchaser's current needs and personal
contingencies, (ii) the Purchaser can afford to suffer a complete loss of his or
her investment in the Shares, (iii) the Purchaser understands and has taken
cognizance of all risk factors related to the purchase of the Shares, (iv) the
Purchaser's knowledge and experience in financial and business matters are such
that the Purchaser is capable of evaluating the merits and risks of the
Purchaser's purchase of the Shares as contemplated by this Agreement


                                       5

<PAGE>

or, in the alternative, the Purchaser has obtained such professional advice as
the Purchaser determined was necessary to enable the Purchaser to evaluate such
merits and risks and (v) the Purchaser is an employee and/or a manager of the
Company or one of its subsidiaries or Associated Entities.

4. RESTRICTION ON TRANSFER. Except for transfers permitted by clauses (x), (y)
and (z) of Section 3(a) or sales of Shares pursuant to an effective registration
statement under the Act filed by the Company as contemplated by Section 10
hereof or pursuant to the Sale Participation Agreement, the Purchaser agrees
that the Purchaser will not transfer any Shares at any time prior to the sixth
anniversary of the Closing Date. No transfer of any such shares in violation
hereof shall be made or recorded on the books of the Company and any such
transfer shall be void and of no effect. The Articles require the Directors of
the Company to refuse to register a transfer attempted to be made in violation
of the terms hereof.

5. RIGHT OF FIRST REFUSAL. If, at any time after the sixth anniversary of the
Closing Date and prior to a Public Offering (as hereinafter defined), the
Purchaser receives a bona fide offer to purchase any or all of the Purchaser's
Shares (the "OFFER") from a third party (the "OFFEROR") which the Purchaser
wishes to accept, the Purchaser shall cause the Offer to be reduced to writing
and shall notify the Company in writing of the Purchaser's wish to accept the
Offer. The Purchaser's notice shall contain an irrevocable offer to sell such
Shares to the Trinity Trustee (in the manner set forth below) at a purchase
price equal to the price contained in, and on the same terms and conditions of,
the Offer, and shall be accompanied by a copy of the Offer (which shall identify
the Offeror). The Company shall forward such notice to the Trinity Trustee
within seven days of its receipt by the Company. At any time within 20 days
after the date of the receipt by the Trinity Trustee of the Purchaser's notice,
the Trinity Trustee shall have the right and option to purchase, or to arrange
for a third party to purchase, all of the Shares covered by the Offer either (i)
at the same price and on the same terms and conditions as the Offer or (ii) if
the Offer includes any consideration other than cash, then at the sole option of
the Trinity Trustee, at the equivalent all cash price, determined in good faith
by the Trinity Trustee, by delivering a certified bank check or checks in the
appropriate amount (and any such non-cash consideration to be paid) to the
Purchaser at the principal office of the Company against delivery of
certificates or other instruments representing the Shares so purchased (and such
other documents as the Trinity Trustee may reasonably require), appropriately
endorsed by the Purchaser. If at the end of such 20 day period, the Trinity
Trustee has not tendered the purchase price for such shares in the manner set
forth above, the Purchaser may during the succeeding 20 day period sell not less
than all of the Shares covered by the Offer to the Offeror at a price and on
terms no less favorable to the Purchaser than those contained in the Offer.
Promptly after such sale, the Purchaser shall notify the Company of the
consummation thereof and shall furnish such evidence of the completion and time
of completion of such sale and of the terms thereof as may reasonably be
requested by the Company. If, at the end of 20 days following the expiration of
the 20 day period for the Trinity Trustee to purchase the Shares, the Purchaser
has not completed the sale of such Shares as aforesaid, all the restrictions on
sale, transfer or assignment contained in this Agreement shall again be in
effect with respect to such Shares.

6. PURCHASER'S SALE OF SHARES TO THE TRINITY TRUSTEE AND PURCHASER'S SALE OF
OPTIONS TO THE COMPANY UPON THE PURCHASER'S DEATH OR DISABILITY. (a) Except as
otherwise provided herein, if, prior to the sixth anniversary of the Closing
Date, (x)(i) the Purchaser is still in the employ of, or still acts in a
managerial or directorial capacity in respect of, the Company or any subsidiary
or Associated Entity of the Company or (ii) the Purchaser has retired from the
Company or one of its subsidiaries or Associated Entities at age 65 or over (or
such other age as applies in the applicable jurisdiction or with respect to
certain classes of Purchasers pursuant to an existing, written Willis policy or
employment agreement, or as may be approved by the Board) after having been
employed by or having acted in a managerial or directorial capacity for the
Company or any subsidiary or Associated Entity of the Company for at least three
years after the Closing Date (retirement in such circumstances is referred to as
a "QUALIFIED RETIREMENT") and (y) the Purchaser either dies or becomes
"PERMANENTLY DISABLED" (as defined herein), then the Purchaser, the Purchaser's
Estate or a Purchaser's Trust (each, a "PURCHASER ENTITY"), shall, for twelve
(12) months following the date of death or permanent disability, have the right:

                  (A) with respect to the Shares, to sell to the Trinity
Trustee, and the Trinity Trustee shall be required to purchase, on one occasion,
all or any portion of the Shares then held by each of the applicable Purchaser
Entities, at the Section 6(a) Repurchase Price, as determined in accordance with
Section 8 hereof; and

                  (B) with respect to the exercisable Options, to require the
Company to pay to the applicable Purchaser Entities an additional amount equal
to the Option Excess Price (as defined in Section 9(b)), if any, as provided in
Section 9(b)(ii); PROVIDED, HOWEVER, that if the Purchaser is resident in the
United Kingdom for purposes of U.K. national insurance regulations, then the
Purchaser Entities shall not be entitled to receive the Option Excess Price with
respect to exercisable Options but shall instead be required to exercise their
exercisable Options in order to be entitled to receive payment for the Option
Shares issued in respect thereof upon purchase by the Trinity Trustee of such
Option Shares pursuant to the preceding clause (A). Notwithstanding anything to
the contrary provided herein, all Options will vest and become exercisable upon
the Purchaser's death or permanent disability only if such death or disability
occurs while the Purchaser is employed by the Company or a subsidiary thereof.
Options will be automatically terminated as set forth in Section 9(b)(i).

         (b) In the event the applicable Purchaser Entities intend to exercise
their rights pursuant to Section 6(a), such Purchaser Entities shall send a
single, combined written notice to the Company of their intention to sell Shares
in exchange for the payment referred in Section 6(a)(A) and/or to terminate such
Options in exchange for the payment referred to in Section 6(a)(B) and shall
indicate the number of Shares to be sold and the number of Options to be
terminated with payment in respect thereof (the "REDEMPTION NOTICE"). The
completion of the purchase shall take place at the principal office of the
Company on the tenth business day after the giving of the Redemption Notice to
the Trinity Trustee by the Company. The applicable Repurchase Price and any
payment with respect to the Options as described above shall be paid by delivery
to the applicable Purchaser Entities, of a certified bank check or checks in the
appropriate amount payable to the order of each of the applicable Purchaser
Entities, against delivery of certificates or other instruments representing the
Shares so purchased and appropriate documents cancelling the Options so
terminated (or such other documents as the Trinity Trustee


                                       7

<PAGE>

may reasonably require) appropriately endorsed or executed by the applicable
Purchaser Entities or any duly authorized representative.

         (c) Notwithstanding anything in Section 6(a) to the contrary and
subject to Section 11(a), if the Trinity Trustee requires financing from the
Company in order to make any payment contemplated by this Section 6 and if the
Company fails to provide financing on limited recourse terms reasonably
acceptable to the Trinity Trustee or if there exists and is continuing a default
or an event of default on the part of the Company or any subsidiary of the
Company under any loan, guarantee or other agreement under which the Company or
any subsidiary of the Company has borrowed money or if the purchase by the
Trinity Trustee or the Company, as the case may be, referred to in Section 6(a)
or the loan of funds to the Trinity Trustee by the Company on limited recourse
terms satisfactory to the Trinity Trustee would result in a default or an event
of default on the part of the Trinity Trustee, the Company or any subsidiary of
the Company under any such agreement or if a purchase by the Trinity Trustee or
the Company or the loan of funds to the Trinity Trustee by the Company on
limited recourse terms satisfactory to the Trinity Trustee would not be
permitted by law (each such occurrence being an "EVENT"), then the Trinity
Trustee shall not be obligated to purchase any of the Shares, and the Company
shall not be obligated to purchase any of the Options (or to pay any applicable
Option Excess Price in respect of such Options), from the applicable Purchaser
Entities until the first business day which is 10 calendar days after all of the
foregoing Events have ceased to exist (the "REPURCHASE ELIGIBILITY DATE");
PROVIDED, HOWEVER, that (i) the number of Shares subject to purchase under this
Section 6(c) shall be that number of Shares, and (ii) in the case of a purchase
pursuant to Section 6(a), the number of Exercisable Option Shares (as defined in
Section 9) for purposes of calculating the Option Excess Price payable under
this Section 6(c) shall be the number of Exercisable Option Shares, specified in
the Redemption Notice and held by the applicable Purchaser Entities, at the time
of delivery of a Redemption Notice in accordance with Section 6(b) hereof;
PROVIDED, FURTHER, that the Repurchase Calculation Date (as defined below) shall
be determined in accordance with Section 8 as of the Repurchase Eligibility Date
(unless, in a repurchase pursuant to Section 6(a), the Section 6(a) Repurchase
Price would be greater if the Repurchase Calculation Date had been determined as
if no Event had occurred in which case, solely for purposes of this PROVISO, the
Repurchase Calculation Date shall be determined as if no Event had occurred).
All Options exercisable as of the date of a Redemption Notice, in the case of a
purchase pursuant to Section 6(a), shall continue to be exercisable until the
purchase of such Options pursuant to such Redemption Notice, provided that to
the extent any Options are exercised after the date of such Redemption Notice,
the number of Exercisable Option Shares for purposes of calculating the Option
Excess Price shall be reduced (and the number of Option Shares to be purchased
in connection with such additional exercise of Options shall be correspondingly
increased) accordingly.

7. THE TRINITY TRUSTEE'S OPTION TO PURCHASE SHARES AND THE COMPANY'S OPTION TO
PURCHASE OPTIONS OF PURCHASER. (a) If, prior to the sixth anniversary of the
Closing Date, (i) the Purchaser's employment with and/or managerial or
directorial activities in favor of the Company or any subsidiary or Associated
Entity of the Company are terminated by the Company (or such subsidiary or
Associated Entity) with Cause (as defined in Section 8(f) below), (ii) the
beneficiaries of a Purchaser's Trust shall include any person or entity other
than the Purchaser, his or her spouse or his or her lineal descendants
(including children by adoption and step children), or (iii) the Purchaser shall
transfer or attempt to effect a transfer of any of the Shares


                                       8

<PAGE>

other than as permitted in this Agreement (each, a "SECTION 7(a) CALL EVENT"),
then:

                  (A) the Trinity Trustee shall have the right, with respect to
the Shares, to purchase all or any portion of the Shares then held by the
applicable Purchaser Entities at the Section 7(a) Repurchase Price determined in
accordance with Section 8 hereof; and

                  (B) with respect to the Options, if the Trinity Trustee
exercises the call rights granted under this Section 7(a), all Options (whether
or not then exercisable) held by the applicable Purchaser Entities will
terminate immediately without payment in respect thereof.

         (b) If, prior to the sixth anniversary of the Closing Date, (i) the
Purchaser's employment with and/or managerial or directorial activities in favor
of the Company or any subsidiary or Associated Entity of the Company are
terminated as a result of the death or permanent disability of the Purchaser or
(ii) if the Purchaser dies or becomes permanently disabled after the Qualified
Retirement of the Purchaser from the Company or any of its subsidiaries or
Associated Entities or (iii) the Purchaser's employment and/or managerial or
directorial activities are terminated as a result of the Qualified Retirement of
the Purchaser from the Company or any of its subsidiaries or Associated Entities
(each a "SECTION 7(b) CALL EVENT"), then:

                  (A) the Trinity Trustee shall have the right, with respect to
the Shares, to purchase all or any portion of the Shares then held by the
applicable Purchaser Entities at the Section 6(a) Repurchase Price determined in

exercises the call rights granted under this Section 7(b), all or any portion of
the exercisable Options shall automatically terminate upon payment by the
Company of an amount equal to the Option Excess Price, if any, as provided in
Section 9(b)(ii); provided, however, that if the Purchaser is resident in the
United Kingdom for purposes of U.K. national insurance regulations, then the
Purchaser Entities shall not be entitled to receive the Option Excess Price with
respect to exercisable Options but shall instead be required to exercise their
exercisable Options in order to be entitled to receive payment for the Option
Shares issued in respect thereof upon purchase by the Trinity Trustee of such
Option Shares pursuant to the preceding clause (A); all other Options will be
dealt with in accordance with the terms of Section 9(b)(i)(A) hereof.

         (c) If, prior to the sixth anniversary of the Closing Date, the
Purchaser's employment with and/or managerial or directorial activities in favor
of the Company or any subsidiary or Associated Entity of the Company are
terminated (i) by the Purchaser with Good Reason or (ii) by the Company (or such
subsidiary or Associated Entity) without Cause (each, a "SECTION 7(c) CALL

the Shares, to purchase all or any portion of the Shares then held by the
applicable Purchaser Entities at the Section 7(c) Repurchase Price determined in
accordance with Section 8 hereof; and

                  (B) with respect to the Options, if the Trinity Trustee
exercises the call rights granted under this Section 7(c), all or any portion of
the exercisable Options shall


                                       9

<PAGE>

automatically terminate upon payment by the Company of an amount equal to the
Option Excess Price, if any, as provided in Section 9(b)(iii); provided,
however, that if the Purchaser is resident in the United Kingdom for purposes of
U.K. national insurance regulations, then the Purchaser Entities shall not be
entitled to receive the Option Excess Price with respect to exercisable Options
but shall instead be required to exercise their exercisable Options in order to
be entitled to receive payment for the Option Shares issued in respect thereof
upon purchase by the Trinity Trustee of such Option Shares pursuant to the
preceding clause (A); all other outstanding Options will be dealt with in
accordance with the terms of Section 9(b)(i)(B) hereof.

         (d) If, prior to the sixth anniversary of the Closing Date, the
Purchaser's employment with and/or managerial or directorial activities in favor
of the Company or any subsidiary or Associated Entity are terminated by the
Purchaser without Good Reason (as defined below) (a "SECTION 7(d) CALL EVENT"),
then:

                  (i) the Trinity Trustee shall have the right, with respect to
the Shares, to purchase all or any portion of the Shares then held by the
applicable Purchaser Entities at the Section 7(d) Repurchase Price determined in
accordance with Section 8 hereof; and

                  (ii) with respect to the Options, if the Trinity Trustee
exercises the call rights granted under this Section 7(d), all or any portion of
the exercisable Options shall automatically terminate upon payment by the
Company of an amount equal to the Option Excess Price, if any, as provided in
Section 9(b)(iv); provided, however, that if the Purchaser is resident in the
United Kingdom for purposes of U.K. national insurance regulations, then the
Purchaser Entities shall not be entitled to receive the Option Excess Price with
respect to exercisable Options but shall instead be required to exercise their
exercisable Options in order to be entitled to receive payment for the Option
Shares issued in respect thereof upon purchase by the Trinity Trustee of such
Option Shares pursuant to the preceding clause (i); all other outstanding
Options will be dealt with in accordance with the terms of Section 9(b)(i)(B)
hereof.

         (e) The Trinity Trustee shall have a period of (i) twelve (12) months
from the date of a Section 7(b) Call Event and (ii) sixty (60) days from the
date of any other Call Event (or, if later, with respect to a Section 7(a) Call
Event, the date of discovery of an impermissible transfer constituting a Section
7(a) Call Event), in which to give notice in writing to the Purchaser of its
election to exercise its rights pursuant to this Section 7 ("CALL NOTICE"). The
completion of the purchases pursuant to the foregoing shall take place at the
principal office of the Company on the tenth business day after the giving of
the Call Notice. The applicable Repurchase Price and any payment with respect to
the Options as described in this Section 7 shall be paid by delivery to the
applicable Purchaser Entities of a certified bank check or checks (or through
effecting an electronic funds transfer) in the appropriate amount payable to the
order of each applicable Purchaser Entity against delivery of a share transfer
form and certificates or other instruments representing the Shares so purchased
and appropriate documents cancelling the Options so terminated, appropriately
endorsed or executed by the applicable Purchaser Entity or its authorized
representative.

         (f) Notwithstanding any other provision of this Section 7 to the
contrary and subject to Section 11(a), if there exists and is continuing any
Event, the Trinity Trustee or the Company, as the case may be, shall delay the
purchase of any of the Shares or the Options (or


                                       10

<PAGE>

the payment of the applicable Option Excess Price in respect of such Options)
(pursuant to a Call Notice timely given in accordance with Section 7(e) hereof)
from the applicable Purchaser Entities until the Repurchase Eligibility Date;
PROVIDED, HOWEVER, that (i) the number of Shares subject to purchase under this
Section 7 shall be that number of Shares, and (ii) in the case of a purchase
pursuant to Section 7(b), 7(c) or 7(d), the number of Exercisable Option Shares
for purposes of calculating the Option Excess Price payable under this Section 7
shall be the number of Exercisable Option Shares, held by the applicable
Purchaser Entities at the time of delivery of a Call Notice in accordance with
Section 7(e) hereof; and PROVIDED, FURTHER, that the Repurchase Calculation Date
shall be determined in accordance with Section 8 based on the Repurchase
Eligibility Date (unless (x) in the case of a Section 7(b) Call Event or a
Section 7(c) Call Event, the applicable Repurchase Price would be greater if the
Repurchase Calculation Date had been determined as if no Event had occurred, in
which case the Repurchase Calculation Date shall be determined as if no Event
had occurred, and (y) in the case of a Section 7(a) Call Event or a Section 7(d)
Call Event, the applicable Repurchase Price would be less if the Repurchase
Calculation Date had been determined as if no Event had occurred, in which case
the Repurchase Calculation Date shall be determined as if no Event had
occurred); and PROVIDED, FURTHER, that such delay shall in no event exceed
twelve months. All Options exercisable as of the date of a Call Notice, in the
case of a purchase pursuant to Section 7(b) or 7(c), shall continue to be
exercisable until the purchase of such Options pursuant to such Call Notice,
provided that to the extent that any Options are exercised after the date of
such Call Notice, the number of Exercisable Option Shares for purposes of
calculating the Option Excess Price shall be reduced (and the number of Option
Shares to be purchased in connection with such additional exercise of Options
shall be correspondingly increased) accordingly.

         (g) Section 7(a) Call Events, Section 7(b) Call Events, Section 7(c)
Call Events, and Section 7(d) Call Events shall be collectively referred to as
"CALL EVENTS."

8. DETERMINATION OF REPURCHASE PRICE. (a) The Section 6(a) Repurchase Price,
Section 7(a) Repurchase Price, Section 7(c) Repurchase Price and the Section
7(d) Repurchase Price are hereinafter collectively referred to as the
"REPURCHASE PRICE". The Repurchase Price shall be calculated as of the last day
of the month preceding the later of (i) the month in which the event giving rise
to the repurchase occurs and (ii) the month in which the Repurchase Eligibility
Date occurs (hereinafter called the "REPURCHASE CALCULATION DATE"). The event
giving rise to the repurchase shall be the death, permanent disability,
retirement or termination of employment or managerial or directorial activities,
as the case may be, of the Purchaser, not the giving of any notice required
pursuant to Section 6 or 7.

         (b) The Section 6(a) Repurchase Price shall be a per share Repurchase
Price equal to the Fair Market Value Per Share (as defined in Section 8(g)) as
of the Repurchase Calculation Date.

         (c) The Section 7(a) Repurchase Price shall be a per share Repurchase
Price equal to the lesser of (i) the Per Share Purchase Price and (ii) Fair
Market Value Per Share as of the Repurchase Calculation Date (but shall not be
less than zero); EXCEPT, HOWEVER, if the Purchaser is chargeable in the United
Kingdom under Case 1 of Schedule E as of the date hereof, then the Section 7(a)
Repurchase Price with respect to Shares other than Option Shares shall be a per
share Repurchase Price equal to Tax Fair Market Value Per Share.


                                       11

<PAGE>


         (d) The Section 7(c) Repurchase Price shall be a per share Repurchase
Price (i) with respect to all Shares other than Option Shares, equal to the Fair
Market Value Per Share and (ii) with respect to all Option Shares, equal to the
Book Value Per Share, in each case as of the Repurchase Calculation Date.

         (e) The Section 7(d) Repurchase Price shall be a per share Repurchase
Price (i) with respect to all Shares other than Option Shares, (A) if the Fair
Market Value Per Share is less than the Per Share Purchase Price, the Fair
Market Value Per Share, or (B) if the Per Share Purchase Price is less than the
Fair Market Value Per Share, the Per Share Purchase Price PLUS, (in the case of
(B) only) (1) the Applicable Percentage MULTIPLIED by (2) the excess of the Fair
Market Value Per Share over the Per Share Purchase Price, and (ii) with respect
to all Option Shares, (A) if the Book Value Per Share is less than the Per Share
Purchase Price, the Book Value Per Share, or (B) if the Per Share Purchase Price
is less than the Book Value Per Share, the Per Share Purchase Price PLUS (in the
case of (B) only) (1) the Applicable Percentage MULTIPLIED by (2) the excess, if
any, of Book Value Per Share over the Per Share Purchase Price; EXCEPT, HOWEVER,
that if the Purchaser is chargeable in the United Kingdom under Case 1 of
Schedule E as of the date hereof, then the Section 7(d) Repurchase Price with
respect to all Shares other than Option Shares shall be equal to the Tax Fair
Market Value Per Share. The "APPLICABLE PERCENTAGE" shall mean zero prior to the
second anniversary of the Closing Date, twenty percent (20%) during the period
commencing on the second anniversary of the Closing Date, forty percent (40%)
during the period commencing on the third anniversary of the Closing Date, sixty
percent (60%) during the period commencing on the fourth anniversary of Closing
Date, eighty percent (80%) during the period commencing on the fifth anniversary
of Closing Date, and on and after the sixth anniversary of the Closing Date, one
hundred percent (100%).

         (f) For purposes of this Agreement the following definitions shall
apply: "CAUSE" shall mean (i) the Purchaser's willful and continued failure to
perform Purchaser's material duties with respect to the Company or any
subsidiary or Associated Entity of the Company after reasonable notice and an
opportunity by the Purchaser to cure such conduct within 10 days after the
Purchaser's receipt of such notice, (ii) willful misconduct by the Purchaser in
connection with the Purchaser's employment or managerial or directorial duties
which is injurious to the Company or any subsidiary or Associated Entity of the
Company, (iii) conviction for any criminal act (other than road traffic
violations not involving imprisonment), or (iv) any breach by the Purchaser of
the provisions of Section 16 hereof or of any other non-compete agreement and/or
confidentiality agreement entered into between the Purchaser and the Company or
any subsidiary or Associated Entity of the Company (other than an insubstantial,
inadvertent, and non-recurring breach) or (v) any material violation of any
written Willis policy after reasonable notice and an opportunity to cure within
10 days of the Purchaser's receipt of such notice; "GOOD REASON" shall mean (i)
a reduction in the Purchaser's base salary or a material adverse reduction in
the Purchaser's benefits (other than (a) in the case of base salary, a reduction
that is offset by an increase in the Purchaser's bonus opportunity upon the
attainment of reasonable performance targets established by the Board, or (b) a
general reduction in the compensation or benefits of, or a shift in the general
compensation or benefits schemes affecting a broad group of, employees of the
Company or any of its subsidiaries or Associated Entities), (ii) a material
adverse reduction in Purchaser's principal duties and responsibilities, which
continues beyond 10 days after written notice by the Purchaser to the Company
(or, as the case


                                       12

<PAGE>

may be, a subsidiary or Associated Entity) of such reduction or (iii) a
significant transfer of the Purchaser away from the Purchaser's primary service
area or primary workplace, other than as permitted by the Purchaser's existing
service contracts; PROVIDED, HOWEVER, that a Purchaser shall have a period of 10
days following any of the foregoing occurrences, or the last event in a series
of events which culminates in providing the basis for such notice, during which
such Purchaser may claim that a basis for a Good Reason termination by the
Purchaser has occurred. For avoidance of doubt, neither the Company nor any
subsidiary nor Associated Entity shall be deemed to have terminated any
Purchaser without Cause unless the Company or any such subsidiary or Associated
Entity has served a formal termination notice on such employee.

         (g) As used herein, "FAIR MARKET VALUE PER SHARE" shall mean (i)
following a Public Offering, Market Price Per Share (as defined below), or (ii)
prior to a Public Offering, the fair market value per Common Share, as
determined no less than annually (or more frequently if the Board so determines)
in good faith by the Board, after it has taken into consideration certain
factors (including, without limitation, the general condition of the Company's
industry, the historical performance of the Company, and the Company's financial
and business prospects) and after it has consulted with an independent
investment banking firm selected with the consent of the Group Executive
Committee, such consent not to be unreasonably withheld. In addition, after
determining the Fair Market Value Per Share, except for purposes of determining
Tax Fair Market Value Per Share, the value of an individual Purchaser's Shares
on a per share basis shall not be reduced to reflect the illiquidity or minority
nature associated with such Purchaser's Shares or the fact that such Purchaser's
Shares are non-voting. "TAX FAIR MARKET VALUE PER SHARE" shall mean while the
shares are unquoted on a U.S. national securities exchange or the London Stock
Exchange, Fair Market Value Per Share adjusted by the Board to reflect the
illiquidity and minority nature associated with such Purchaser's Shares, which
valuation shall be determined in accordance with Section 273 of the U.K.
Taxation of Chargeable Gains Act 1992 and is expected to consist of a discount
to Fair Market Value Per Share presumed to be at least 35%; the Board may, but
shall not be required to, consult with any investment banking firm concerning
the appropriate size of any such discount. When the Shares are quoted on a U.S.
national securities exchange or the London Stock Exchange, "Tax Fair Market
Value Per Share" shall be determined in accordance with Section 272 of the U.K.
Taxation of Chargeable Gains Act 1992.

         (h) As used herein, "BOOK VALUE PER SHARE" shall mean (i) after a
Public Offering (as defined below), Market Price Per Share, or (ii) prior to a
Public Offering, the quotient of (a) (i) the aggregate amount invested in the
Company for Common Shares by Profit Sharing, the management of the Company and
its subsidiaries and Associated Entities (including any "roll-over" amounts
invested by management pursuant to the Willis Corroon Group Executive Deferred
Incentive Plan, the Willis Corroon Group Restricted Share Plan and the Willis
Corroon North American Restricted Share Plan), insurance company investors, and
other individuals or entities resulting in the acquisition of 100% of the
Company, PLUS (ii) the aggregate consolidated profit and loss (after taxes,
minority interests, and dividends), of the Company from and after the formation
of the Company, PLUS (iii) the aggregate amount contributed to (or credited to
shareholders' equity of) the Company after the Closing Date as equity of the
Company (including consideration to be received upon exercise of Options and
other share equivalents), PLUS (iv) the aggregate amount of any dividends
accrued on preference shares converted into Common Shares, PLUS or MINUS (v)
other adjustments for certain unusual or


                                       13

<PAGE>

other items recognized by the Company in the sole discretion of the Board,
DIVIDED BY (b) the sum of the number of Common Shares then outstanding and the
number of Common Shares issuable upon the exercise of all outstanding Options
and other rights to acquire Common Shares and the conversion of all securities
convertible into Common Shares. The items referred to in the calculations set
forth in clauses (a)(ii) through (b) of the immediately preceding sentence shall
be determined in good faith, and to the extent possible, in accordance with U.K.
generally accepted accounting principles applied on a basis consistent with any
prior periods as reflected in the consolidated financial statements of the
Company.

         (i) As used herein the term "PUBLIC OFFERING" shall mean the sale of
Common Shares to the public subsequent to the date hereof pursuant to a
registration statement under the Act which has been declared effective by the
SEC (other than a registration statement on Form S-8 or any other similar form)
or a public listing in the U.K., in either case, which results in an active
trading market in at least 35% of the issued and outstanding Common Shares. A
"QUALIFIED PUBLIC OFFERING" shall mean any offering of Common Shares to the
public pursuant to an effective registration statement and such registration
statement includes the sale of Common Shares held by Profit Sharing or its
affiliates.

         (j) As used herein, the term "MARKET PRICE PER SHARE" shall mean the
price per share equal to the average of the last sale price of the Common Shares
on each of the ten trading days prior to the Repurchase Calculation Date on each
exchange on which the Common Shares may at the time be listed or, if there shall
have been no sales on such exchange on any such trading day, the average of the
closing bid and asked prices on such exchange at the end of such trading day or
if there is no such bid and asked price on the next preceding date when such bid
and asked price occurred or, if the Common Shares shall not be so listed, the
average of the closing sales prices as reported by NASDAQ at the end of the
Repurchase Calculation Date in the over-the-counter market.

         (k) In determining the Repurchase Price, appropriate adjustments shall
be made for any stock dividends, splits, combinations, recapitalizations or any
other adjustment in the number of outstanding Common Shares in order to
maintain, as nearly as practicable, the intended operation of the provisions of
this Section 8.

9. SHARES ISSUED TO PURCHASER UPON EXERCISE OF OPTIONS; TERMINATION AND
EXPIRATION OF OPTIONS. (a) Options are subject to the terms of the Option Plan,
Stock Option Agreement and the terms set forth herein.

         (b) (i) (A) In the case of an exercise of the put rights described
above in Section 6(a)(B) or of the call rights described above in Section
7(b)(B), all outstanding exercisable Options that had been granted to the
Purchaser under any Option Plan for which such put or call is exercised will be
automatically terminated upon the payment by the Company to the Purchaser of an
amount equal to the applicable Option Excess Price, as provided below or, in the
case of a Purchaser that is resident in the United Kingdom for purposes of U.K.
national insurance regulations, then all exercisable Options, if not then
exercised, shall be automatically terminated upon payment by the Trinity Trustee
for the Shares (including Option Shares) of the amounts contemplated by Sections
6(a) or 7(b), as the case may be, PROVIDED, HOWEVER, in the event the Option
Excess Price is zero or a negative number, all outstanding exercisable Options


                                       14

<PAGE>

granted to the Purchaser (including any Purchaser resident in the United
Kingdom) under any Option Plan shall remain outstanding and exercisable until
expiration in accordance with the terms of such Option Plan. All outstanding
unexercisable Options shall be automatically terminated without any payment in
respect thereof.

         (B) In the case of an exercise of call rights described above in
Sections 7(c)(B) or 7(d)(ii), all outstanding exercisable Options for which such
call is exercised that had been granted to the Purchaser under any Option Plan
will be automatically terminated upon the payment by the Company to the
Purchaser of an amount equal to the applicable Option Excess Price, as provided
below or, in the case of a Purchaser that is resident in the United Kingdom for
purposes of U.K. national insurance regulations, then all exercisable Options,
if not then exercised, shall be automatically terminated upon payment by the
Trinity Trustee for the Shares (including Option Shares) of the amounts
contemplated by Sections 7(c) or 7(d), as the case may be; PROVIDED, HOWEVER, in

Option Exercise Price, such Option shall be automatically terminated without any
payment in respect thereof. All outstanding unexercisable Options shall be
automatically terminated without any payment in respect thereof.

                  (ii) In the case of an exercise of the put rights described
above in Section 6(a)(B) or of the call rights described above in Section
7(b)(B), with respect to each Option, the "OPTION EXCESS PRICE" is the excess,
if any, of the Section 6(a) Repurchase Price over the Option Exercise Price (as
defined below), MULTIPLIED by the number of Exercisable Option Shares
thereunder.

                  (iii) In the case of an exercise of the call rights described
above in Section 7(c), with respect to each Option, the "OPTION EXCESS PRICE" is
the excess, if any, of the Section 7(c) Repurchase Price applicable to Option
Shares over the Option Exercise Price, MULTIPLIED by the number of Exercisable
Option Shares thereunder.

                  (iv) In the case of an exercise of the call rights described
above in Section 7(d), with respect to each Option, the "OPTION EXCESS PRICE" is
the excess, if any, of the Section 7(d) Purchase Price applicable to Option
Shares over the Option Exercise Price, MULTIPLIED by the number of exercisable
Option Shares thereunder.

         For purposes hereof, "OPTION EXERCISE PRICE" shall mean the exercise
price of the Ordinary Shares covered by the applicable Option, and "EXERCISABLE
OPTION SHARES" shall mean the Ordinary Shares which, at the time of
determination of the Option Excess Price, could be purchased by the Purchaser
upon exercise of his or her outstanding Options.

10. "PIGGYBACK" REGISTRATION RIGHTS. (a) Effective upon the date of this
Agreement, until the later of (i) six years from the Closing Date and (ii) the
first occurrence of (x) a Qualified Public Offering or (y) the existence of an
active trading market in 35% or more of the Common Shares, the Purchaser hereby
agrees to be bound by all of the terms, conditions and obligations of the
Registration Rights Agreement, dated as of December 18, 1998, between the
Company and Profit Sharing (the "REGISTRATION RIGHTS AGREEMENT"), and, in the
case of a Qualified Public Offering, and only in the case of a Qualified Public
Offering, and subject to the limitations set forth in this Section 10, shall
have all of the rights, privileges and obligations of the Registration Rights
Agreement, in each case as if the Purchaser were an original party (other than
the Company) thereto; PROVIDED, HOWEVER, that at no time shall the Purchaser
have any rights to request registration under Section 3 of the Registration
Rights Agreement or be deemed to be a "Demand Party" for any purpose or in any
circumstance; and PROVIDED FURTHER, that the Purchaser shall not be bound by any
amendments to the Registration Rights Agreement that adversely affects their
rights in any way unless the Purchaser consents thereto provided that such
consent will not be unreasonably withheld. Notwithstanding anything to the
contrary contained in the Registration Rights Agreement, the Purchaser's rights
and obligations under the Registration Rights Agreement shall be subject to the
limitations and additional obligations set forth in this Section 10. All Shares
purchased or held by the Purchaser (or by a Purchaser Entity) pursuant to this
Agreement shall be deemed to be Registrable Securities as defined in the
Registration Rights Agreement.

         (b) The Company will promptly notify the Purchaser in writing (a
"NOTICE") of any proposed registration (a "PROPOSED REGISTRATION") in connection
with a Qualified Public Offering. If within 15 days of the receipt by the
Purchaser of such Notice, the Company receives from the applicable Purchaser
Entities a written request (a "REQUEST") to register Shares held by the
applicable Purchaser Entities (which Request will be irrevocable unless
otherwise mutually agreed to in writing by the Purchaser and the Company),
Shares will be so registered as provided in this Section 10; PROVIDED, HOWEVER,
that for each such registration statement only one Request, which shall be
executed by the applicable Purchaser Entities, may be submitted for all
Registrable Securities held by the applicable Purchaser Entities.

         (c) The maximum number of Ordinary Shares which will be registered
pursuant to a Request will be the lowest of (i) (A) the number of Shares then
held by the Purchaser, including all Shares which the Purchaser Entities are
then entitled to acquire under an unexercised Option to the extent then
exercisable multiplied by (B) a fraction, the numerator of which is the number
of Common Shares being sold by Profit Sharing and investment partnerships and
investment limited liability companies affiliated with Kohlberg Kravis Roberts &
Co. L.P. ("KKR") and the denominator of which is the number of Common Shares
owned by Profit Sharing and investment partnerships and investment limited
liability companies affiliated with KKR, (ii) the maximum number of Shares which
the Company can register in the Proposed Registration without adverse effect on
the offering in the view of the managing underwriters (reduced pro rata with all
Other Management and Employee Shareholders) as more fully described in
subsection (d) of this Section 10 or (iii) the maximum number of Ordinary Shares
which the Purchaser (pro rata based upon the aggregate number of Ordinary Shares
the Purchaser and all Other Management and Employee Shareholders have requested
to be registered) and all Other Management and Employee Shareholders are
permitted to register under the Registration Rights Agreement.

                                       16

<PAGE>

         (d) If a Proposed Registration involves an underwritten offering and
the managing underwriter advises the Company in writing that, in its opinion,
the number of Common Shares requested to be included in the Proposed
Registration exceeds the number which can be sold in such offering, so as to be
likely to have an adverse effect on the price, timing or distribution of the
Common Shares offered in such Qualified Public Offering as contemplated by the
Company, then the Company will include in the Proposed Registration (i) first,
either (x) 100% of the Common Shares the Company proposes to sell or (y) in the
case of a registration request by a "DEMAND PARTY" pursuant to (and as defined
in) Section 3 of the Registration Rights Agreement by and among certain
insurance carriers or their affiliates and the Company dated as of July 22,
1998, and as such agreement may be amended from time to time (the "CARRIER
REGISTRATION RIGHTS AGREEMENT"), 100% of the "REGISTRABLE SECURITIES" of the
requesting "HOLDERS" as contemplated by (and as defined in) Section 3 of the
Carrier Registration Rights Agreement and, in either event, (ii) second, to the
extent of the number of Common Shares requested to be included in such
registration which, in the opinion of such managing underwriter, can be sold
without having the adverse effect referred to above, the number of Common Shares
which the "HOLDERS" and "OTHER HOLDERS" (as defined in the Registration Rights
Agreement), including, without limitation, the Purchaser and Other Management
and Employee Shareholders have requested to be included in the Proposed
Registration, such amount to be allocated pro rata among all requesting Holders
and Other Holders on the basis of the relative number of Common Shares then held
by each such Holder and Other Holder (provided that any shares thereby allocated
to any such Holder that exceed such Holder's request will be reallocated among
the remaining requesting Holders in like manner).

         (e) Upon delivering a Request the Purchaser will, if requested by the
Company, execute and deliver a custody agreement and power of attorney in form
and substance satisfactory to the Company with respect to the Shares to be
registered pursuant to this Section 10 (a "CUSTODY AGREEMENT AND POWER OF
ATTORNEY"). The Custody Agreement and Power of Attorney will provide, among
other things, that the Purchaser will deliver to and deposit in custody with the
custodian and attorney-in-fact named therein a certificate or certificates

and attorney-in-fact with full power and authority to act under the Custody

11. PRO RATA REPURCHASES; DIVIDENDS. (a) Notwithstanding anything to the
contrary contained in Section 6, 7 or 8, if at any time consummation of all
purchases and payments to be made by the Trinity Trustee or the Company, as the
case may be, pursuant to this Agreement and the Other Management and Employee
Shareholders' Agreements would result in an Event, then the Trinity Trustee or
the Company, as the case may be, shall first make purchases from, and payments
to, any Purchaser's Estate and the estate of any Other Management and Employee
Shareholders who have died or become permanently disabled while employed (and/or
while acting in a managerial or directorial capacity) or following Qualified
Retirement pro rata and, second, to any other Purchaser and Other Management and
Employee Shareholders pro rata (in each case, on the basis of the proportion of
the number of Shares and the number of Options each such Purchaser's Estate and
such other estates, and each Purchaser and all Other Employee Shareholders, as
the case may be, have elected or are required to sell to the Trinity Trustee or
the Company, as the case may be) for the maximum number of Shares and shall pay
the Option Excess Price for the maximum number of Options permitted without
resulting in an Event (the "MAXIMUM REPURCHASE AMOUNT"). The provisions of
Section 6(c) and 7(f) shall apply in their entirety to payments and repurchases
with respect to Options and Shares which may not be made due to the limits
imposed by the Maximum Repurchase Amount under this Section 11(a). Until all of
such Shares and Options are purchased and paid for by the Trinity Trustee or the
Company, as the case may be, the Purchaser and the Other Management and Employee
Shareholders whose Shares and Options are not purchased in accordance with this
Section 11(a) shall have priority, on a pro rata basis, over other purchases of
Ordinary Shares and Options by the Trinity Trustee or the Company, as the case
may be, pursuant to this Agreement and Other Management and Employee
Shareholders' Agreements.

         (b) No dividends on the Ordinary Shares are expected to be paid by the
Company prior to a Public Offering. In the event any dividends are paid with
respect to the Ordinary Shares, the Purchaser will be treated in the same manner
as all other shareholders with respect to Ordinary Shares then owned by the
Purchaser.

12. RIGHTS TO NEGOTIATE PURCHASE PRICE. Nothing in this Agreement shall be
deemed to restrict or prohibit the Trinity Trustee or the Company, as the case
may be, from purchasing Shares or Options from the Purchaser at any time, upon
such terms and conditions, and for such price, as may be mutually agreed upon
between the parties, whether or not at the time of such purchase circumstances
exist which specifically grant the Trinity Trustee the right to purchase, or the
Purchaser the right to sell, Shares or the Company has the right to pay, or the
Purchaser has the right to receive, the Option Excess Price under the terms of
this Agreement.

13. ASSIGNABILITY OF CERTAIN RIGHTS BY THE TRINITY TRUSTEE. The Trinity Trustee
shall have the right to assign any or all of its rights or obligations to
purchase Shares pursuant to Sections 5, 6 and 7 hereof to the Company or Profit
Sharing or an affiliate of Profit Sharing.


                                       18

14. BOARD DISCRETION. In the event a Purchaser's employment and/or managerial or
directorial duties are terminated or, in the event a Purchaser experiences a
personal or financial hardship, the Board may, in its sole discretion, determine
to apply more favorable terms to such Purchaser's Shares and Options than those
established in this Agreement, and the relevant member of the Group Executive
Committee may recommend to the Board that more favorable terms be applied. In
addition, in the event of a sale or other disposition of any subsidiary,
Associated Entity, division or business by the Company (or any of its
subsidiaries), the Board shall, in its sole discretion, determine whether a
termination of employment of a Purchaser has occurred for purposes of this
Agreement and the conditions applicable to such termination, after consideration
of any recommendation by the Group Executive Committee.

15. REPRESENTATIONS AND WARRANTIES OF THE COMPANY AND THE TRINITY TRUSTEE. The
Company represents and warrants to the Purchaser that (A) this Agreement has
been duly authorized, executed and delivered by the Company and constitutes a
valid and legally binding obligation of the Company enforceable against the
Company in accordance with its terms, and (B) the Shares, when issued, delivered
and paid for in accordance with the terms hereof, will be duly and validly
issued, fully paid and nonassessable. The Trinity Trustee represents and
warrants to the Purchaser that this Agreement has been duly authorized, executed
and delivered by the Trinity Trustee and constitutes a valid and legally binding
obligation of the Trinity Trustee enforceable against the Trinity Trustee in
accordance with its terms.

16. COVENANT NOT TO COMPETE; SEVERANCE; CONFIDENTIAL INFORMATION. In
consideration of the Company entering into this Agreement with the Purchaser,
the Purchaser hereby agrees effective as of the Closing Date, without the
Company's prior written consent, the Purchaser shall not (i) directly or
indirectly, at any time during or after the Purchaser's employment with the
Company, a subsidiary or an Associated Entity, disclose any Confidential
Information (as defined below) and shall use his or her best efforts to prevent
the taking or disclosure of any Confidential Information pertaining to the
business of the Company or any of its subsidiaries or Associated Entities,
except when required by law; or (ii) unless the Purchaser and the Company (or
any of its subsidiaries or Associated Entities) are already party to a valid and
enforceable agreement which provides for a covenant not to compete (in which
case such agreement shall control), at any time during the Purchaser's
employment with the Company or a subsidiary or Associated Entity and for twelve
months thereafter, directly or indirectly (A) be engaged in or have financial
interest (other than an ownership position of less than 5% in any company whose
shares are publicly traded or any non-voting non-convertible debt securities in
any company) in any business in Competition (as defined below) with the
Restricted Group (as defined below) or (B) solicit, accept or perform, other
than on the Restricted Group's behalf, insurance or bond brokerage, agency, risk
management, claims administration, self-insurance, consulting or other business
performed by the Restricted Group for any client with whom the Purchaser has had
business dealings, or any prospective client from whom the Purchaser has
participated in soliciting business, in either case within the last 12 months of
the Purchaser's employment with the Company, a subsidiary or an Associated
Entity; PROVIDED, HOWEVER, that the Company may, at its option, pay the
Purchaser (if the Purchaser is subject to clause (ii) above) severance payments
in consideration for extending this restrictive covenant for an additional
twelve months; PROVIDED, FURTHER, that the Company may, at its option, require
the Purchaser (if the Purchaser is subject to clause (ii) above) to be on paid
leave for the entire or any portion of the foregoing 24 month period. As used in
this Agreement, the term "CONFIDENTIAL INFORMATION"


                                       19

<PAGE>

means all non-public information concerning the financial data, strategic
business plans, and other non-public, proprietary, and confidential information
of the Company or any of its subsidiaries or affiliated entities (the
"RESTRICTED GROUP") as in existence during the Purchaser's employment with, or
performance of managerial or directorial duties for, the Company (and/or a
subsidiary or Associated Entity) and as of the date of any termination of such
employment or the performance of such duties. As used in this Agreement, and
except as otherwise defined in a valid and enforceable agreement between the
Purchaser and the Company or a subsidiary or Associated Entity, a business shall
be in "COMPETITION" if it is principally engaged in any business active in the
insurance or surety or fidelity bond brokerage, agency, risk management, claims
administration, self-insurance, risk management consulting or other business
performed by the Company, a subsidiary or Associated Entity or if it is a
business in which any of the Company, a subsidiary or an Associated Entity has
taken steps toward engaging. This Section 16 shall not apply to a Purchaser who
is a UK or Irish employee. Any such Purchaser will, if so informed by the
Company, be required to enter into separate confidentiality and post employment
restraints as a condition of the Purchase of any Shares. A Purchaser shall be
considered a UK or Irish employee if and for so long as: (a) the contract of
employment of the Purchaser is with Willis Group or any of its UK or Irish
subsidiaries and the Purchaser ordinarily works in Great Britain or Ireland and
any work he or she may do outside Great Britain or Ireland is for the same
employer; or (b) the law which governs the Purchaser's contract of employment is
the law of England and Wales, the law of Scotland or the law of Ireland.

17. COVENANT REGARDING 83(b) ELECTION. Except as the Company may otherwise agree
in writing, the Purchaser hereby covenants and agrees that, if the Purchaser is
a U.S. taxpayer, he or she will make an election provided pursuant to Treasury
Regulation 1.83-2 with respect to the Shares, including without limitation, the
Shares to be acquired pursuant to Section 1 and the Shares to be acquired upon
each exercise of the Purchaser's Options; and the Purchaser further covenants
and agrees, if the Purchaser is a U.S. taxpayer, that he or she will furnish the
Company with copies of the forms of election the Purchaser files within 30 days
after the date hereof, and within 30 days after each exercise of Purchaser's
Options and with evidence that each such election has been filed in a timely
manner.

18. NOTICE OF CHANGE OF BENEFICIARY. Immediately prior to any transfer of Shares
to a Purchaser's Trust, the Purchaser shall provide the Company with a copy of
the instruments creating the Purchaser's Trust and with the identity of the
beneficiaries of the Purchaser's Trust. The Purchaser shall notify the Company
as soon as practicable prior to any change in the identity of any beneficiary of
the Purchaser's Trust.

19. EXPIRATION OF CERTAIN PROVISIONS. The provisions contained in Sections 5, 6
and 7 of this Agreement and the portion of any other provision of this Agreement
which incorporates the provisions of Sections 5, 6 and 7, shall terminate and be
of no further force or effect with respect to any Shares sold by the Purchaser
(i) pursuant to an effective registration statement filed by the Company
pursuant to Section 10 hereof or (ii) pursuant to the terms of the Sale
Participation Agreement of even date herewith between the Purchaser and Profit
Sharing.

         The provisions contained in Sections 4, 5, 6, 7 and 17 of this
Agreement, and the portion of any other provisions of this Agreement which
incorporate the provisions of such


                                       20

<PAGE>

Sections, shall terminate and be of no further force or effect upon a "CHANGE OF
CONTROL", as defined in the Option Plan.

         Except as set for the above, such provisions shall not terminate in the
event of any public offering or stock exchange listing of Common Shares.

20. RECAPITALIZATIONS, ETC. The provisions of this Agreement shall apply, to the
full extent set forth herein with respect to the Shares or the Options, to any
and all shares of capital stock of the Company or any capital stock, partnership
units or any other security evidencing ownership interests in any successor or
assign of the Company (whether by merger, consolidation, sale of assets or
otherwise) which may be issued in respect of, in exchange for, or substitution
of the Shares or the Options, by reason of any stock dividend, split, reverse
split, bonus issue, combination, recapitalization, liquidation,
reclassification, merger, consolidation or otherwise, with appropriate
adjustments to per share repurchase prices, as may be determined in good faith
by the Board of Directors in a manner consistent with any adjustments to the
Options.

21. U.S. STATE SECURITIES LAWS. The Company hereby agrees to use its reasonable
best efforts to comply with all U.S. state securities or "blue sky" laws which
might be applicable to the sale of the Shares and the issuance of the Options to
the Purchaser.

22. BINDING EFFECT. The provisions of this Agreement shall be binding upon and
accrue to the benefit of the parties hereto and their respective heirs, legal
representatives, successors and assigns. In the case of a transferee permitted
under Section 3(a) hereof, such transferee shall be deemed the Purchaser
hereunder; provided, however, that no transferee (including without limitation,
transferees referred to in Section 3(a) hereof) shall derive any rights under
this Agreement unless and until such transferee has delivered to the Company a
valid undertaking and becomes bound by the terms of this Agreement.

23. AMENDMENT. This Agreement may be amended only by a written instrument signed
by the Parties hereto.

24. NOTICES. All notices and other communications required or permitted to be

25. APPLICABLE LAW; SUBMISSION TO JURISDICTION. This Agreement and the rights
and duties of the parties hereunder shall be governed by and construed in
accordance with the laws of the State of New York. Any suit, action or
proceeding against the Purchaser with respect to this Agreement, or any judgment
entered by any court in respect of any thereof, may be brought (i) with respect
to any Purchaser who is a resident of the United States of America, in any court
of competent jurisdiction in the State of New York or located in the City of New
York, as the Company may elect in its sole discretion or (ii) with respect to
any other Purchaser, in any court of competent jurisdiction in England and
Wales, as the Company may elect in its sole discretion and the Purchaser hereby
submits accordingly to the nonexclusive jurisdiction of such courts for the
purpose of any such suit, action, proceeding or judgment. By the execution and
delivery of this Agreement, the Purchaser irrevocably appoints CT Corporation
System, at its office at 1633 Broadway, New York, New York or Willis Group
Limited, at its registered office for the time being, as the case may be, as his
or her agent upon which process may be served in any such suit, action or
proceeding. Service of process upon such agent, together with notice of such
service given to the Purchaser in the manner provided in Section 24 hereof shall
be deemed in every respect effective service of process upon him or her in any
suit, action or proceeding. Nothing herein shall in any way be deemed to limit
the ability of the Company or the Trinity Trustee to serve any such writs,
process or summonses in any other manner permitted by applicable law or to
obtain jurisdiction over the Purchaser, in such other jurisdictions, and in such
manner, as may be permitted by applicable law. The Purchaser hereby irrevocably
waives any objections which he or she may now or hereafter have to the laying of
the venue of any suit, action or proceeding arising out of or relating to this

Wales, if the Purchaser is a resident of any other jurisdiction, and hereby
further irrevocably waives any claim that any such suit, action or proceeding
brought in any such court has been brought in any inconvenient forum. No suit,
action or proceeding against the Company or the Trinity Trustee with respect to
this Agreement may be brought in any court, domestic or foreign, or before any
similar domestic or foreign authority other than in a court of competent
jurisdiction in the State of New York or in England or Wales, and the Purchaser
hereby irrevocably waives any right which he or she may otherwise have had to
bring such an action in any other court, domestic or foreign, or before any
similar domestic or foreign authority. The Company and the Trinity Trustee each
hereby submits accordingly to the jurisdiction of such courts for the purpose of
any such suit, action or proceeding.

26. SECTION AND OTHER HEADINGS, ETC. The section and other headings contained in
