              tax counsel to the Purchaser, addressed to the Vendors,

               which any of them may desire or be obliged to make regarding this
               Agreement. Any other communication which the parties may make
               concerning the foregoing matters shall, subject to the
               requirements of law or any regulatory body or the rules and
               regulations of any recognised stock exchange, be consistent with
               any such formal announcement or circular as aforesaid. 

       9.2.2   Subject to Clause 9.2.1, no party shall pending Completion make
               or authorise or issue any formal announcement or circular
               concerning the subject matter of this Agreement or any other
               document or transaction referred to in or contemplated by this

customer of the Group nor employ or attempt to employ or divert an employee of
the Group and shall forthwith hand over, destroy (in which case the Purchaser
shall deliver a certificate of destruction signed by a director of the Purchaser
in such terms as the Vendors' Representative may reasonably request) or procure
the handing over or destruction of all 

                                      -26-
<PAGE>
 
accounts, records, documents and papers of or relating to the Vendors and each
Group Company which shall have been made available to it and all copies or other
records derived from such materials, and expunge any information derived from
such materials or otherwise concerning the subject matter of this Agreement from
any computer, wordprocessor or other device containing information. Provided
that this shall not apply:

       9.3.1  to information available from public records or information 
              acquired by the Purchaser otherwise than from the Vendors or their
              agents or any Group Company: or

       9.3.2  to information which was lawfully in the Purchaser's possession 
              prior to the disclosure of information disclosed to the Purchaser
              and/or its agents pursuant to the Confidentiality Agreement, so
              long as the Purchaser can demonstrate by written or other
              reasonable evidence that the source of such information was not
              known by the Purchaser or its agents, after reasonable
              investigation to be bound by a confidentiality agreement or was
              subject to other contractual, legal or fiduciary obligation of
              confidentiality to the Group with respect to such information, or

       9.3.3  to information which became available to the Purchaser on a non-
              confidential basis from a source other than the Group or its
              agents, provided that such source was not known by the Purchaser
              or any of its agents, after reasonable investigation to be bound
              by a confidentiality agreement with or other contractual, legal or
              fiduciary obligation of confidentiality to the Group or their
              agents with respect to such information.

9.4  Successors and Assigns

       9.4.1  Subject to Clause 9.4.2, this Agreement is personal to the parties
              to it. Accordingly, neither the Purchaser nor the Vendors nor the
              Company may, without the prior written consent of the others,
              assign the benefit of all or any of the others' obligations under
              this Agreement, nor any benefit arising under or out of this
              Agreement.

       9.4.2  Except as otherwise expressly provided in this Agreement, the 
              Purchaser may, without the consent of the Vendors or the Company,
              assign to a connected company the benefit of all or any of the
              Vendors' obligations under this Agreement provided that such
              assignment shall not be absolute but shall be expressed to have
              effect only for so long as the assignee remains a connected
              company. For the purposes of this sub-clause a connected company
              is a company which is a wholly-owned subsidiary of the party
              concerned or which is a holding company of such party or a
              subsidiary of such holding company.

9.5  Variation

No variation of this Agreement shall be effective unless in writing and signed
by or on behalf of each of the parties to this Agreement.

9.6  Time of the Essence

Any time, date or period referred to in any provision of this Agreement may be
extended by mutual agreement between the parties (the Vendors' Representative
acting on behalf of the Remaining Vendors) but as regards any time, date or
period originally fixed or any time, date or period so extended time shall be of
the essence.

9.7  Further Assurance

The Vendors severally agree with the Purchaser that, at any time after the date
of this Agreement, they shall and shall use their reasonable best endeavours to
procure that any necessary third party shall at the cost of the Purchaser
execute such documents and do such acts and things as the Purchaser may
reasonably require for the purpose of giving to the Purchaser the full benefit
of all the provisions of this Agreement.

9.8  Interest

If the Vendors or the Purchaser default in the payment when due of any sum
payable under this Agreement (whether determined by agreement or pursuant to an
order of a court or otherwise) the liability of the Vendors or the Purchaser (as
the case may be) shall be increased to include interest on such sum from the
date when such payment is due until the date of actual payment (as well after as
before judgment) at a rate per annum of 2 per cent. above the base rate from
time to time of Lloyds Bank PLC. Such interest shall accrue from day to day.

1.   Shelf Registration and Listing

1.1  The Purchaser shall prepare and file with the United States Securities and
     Exchange Commission (the "SEC"), as promptly as practicable after the
     Completion Date (but in no event later than the date which is 30 calendar
     days after the Completion), a registration statement pursuant to Rule 415
     under the Securities Act covering all of the Consideration Shares to be
     issued pursuant to this Agreement (the "Purchaser Registration Statement".
     The Purchaser Registration Statement shall be on Form S-3 or another
     appropriate form permitting registration of the Consideration Shares for
     resale by the Vendors. The Purchaser shall not permit any securities to be
     included in the Purchaser Registration Statement other than the
     Consideration Shares to be issued pursuant to this Agreement. The Purchaser
     shall use its reasonable best efforts to cause the Purchaser Registration
     Statement to be declared effective pursuant to the Securities Act as soon
     as practicable after the filing thereof and to keep the Purchaser
     Registration Statement continuously effective under the Securities Act
     until the earlier of (i) the date which is 24 months following the
     Completion Date, (ii) the date that all Consideration Shares covered by the
     Purchaser Registration Statement have been sold in the manner set forth and
     as contemplated in the Purchaser Registration Statement or (iii) the date
     on which each Vendor could sell all of its Consideration Shares issued
     pursuant to this Agreement at one time pursuant to Rule 144 (other than
     Rule 144(k)) promulgated under the Securities Act (the "Effectiveness
     Period"). Each Vendor shall notify Purchaser in writing of the date that
     all of its Consideration Shares have been sold in the manner set forth and
     as contemplated in the Purchaser Registration Statement.

1.2  The Purchaser shall use its reasonable best efforts to keep the Purchaser
     Registration Statement continuously effective during the Effectiveness
     Period by supplementing and amending the Purchaser Registration Statement
     if required by the rules, regulations or instructions applicable to the
     registration form used for such Purchaser Registration Statement. In the
     event of an issuance of any stop order suspending the effectiveness of the
     Purchaser Registration Statement, or any order suspending or preventing the
     use of any related prospectus or suspending the qualification of the
     Consideration Shares included in such Purchaser Registration Statement for
     sale in any jurisdiction, the Purchaser will use its reasonable best
     efforts promptly to obtain the withdrawal of such order. In the event of
     the issuance of any such stop order, the Effectiveness Period (if
     calculated under Section 1.1(i)) will be extended by the number of days
     such stop order is in effect.

1.3  The Purchaser may suspend sales under the Purchaser Registration Statement
     or defer the updating of the Purchaser Registration Statement and suspend
     sales thereunder for a reasonable period of time (not exceeding 60 days) if
     the Purchaser furnishes the Vendors (with such notice to be sent to the
     Vendors Representative in the case of the Remaining Vendors) with a notice
     signed by an executive officer of the Purchaser (a "Suspension Notice")
     stating that, in its good faith judgment, the Purchaser has determined that
     maintaining the effectiveness of the Purchaser Registration Statement and
     permitting offers and sales thereunder would require the Purchaser to make
     public disclosure of information not otherwise required to be publicly
     disclosed at such time, the public disclosure of which would have Material
     Adverse Effect upon the Purchaser or would adversely affect the ability of
     the Purchaser to consummate a material financing, acquisition, disposition
     of assets or stock, merger or other comparable transaction. Upon the
     receipt of any such notice from the Purchaser, each Vendor agrees to
     discontinue disposition of Consideration Shares pursuant to the Purchaser
     Registration Statement (a "Black Out") until the earlier of (i) such time
     as such Vendor receives copies of a supplemental or amended prospectus,
     (ii) such time as such Vendor receives notification from the Purchaser that
     such suspension is no longer required or (iii) 60 days, provided, that the 
     Purchaser may not suspend sales for more than aggregate of 90 days in any
     twelve-month period.

                                      -47-
<PAGE>
 

     In the event the Purchaser shall give a Suspension Notice, the
     Effectiveness Period will be extended by the number of days during the time
     period from and including the date of the giving of such Suspension Notice
     to and including the date when the Black-Out shall have terminated in
     accordance with the immediately preceding paragraph.

2.   Registration Procedures.

     In any offering hereunder, the Purchaser shall:

2.1  Before filing the Purchaser Registration Statement, any prospectus
     supplement or any pre- or post-effective amendment to the Purchaser
     Registration Statement in connection with the offering of Consideration
     Shares, the Purchaser will furnish to the Vendors Representative copies of
     all such documents proposed to be filed and a reasonable opportunity to
     comment thereon.

2.2  Subject to Section 2.1 above, prepare and file such post-effective
     amendments to the Purchaser Registration Statement as may be necessary to
     keep it continuously effective for the Effective Period (including any
     extensions thereof in accordance with Section 1.3); cause the related
     prospectus to be supplemented by any required prospectus supplement, and as
     so supplemented to be filed pursuant to Rule 424 (or any similar provisions
     then in force) under the Securities Act; and comply with the provisions of
     the Securities Act with respect to the disposition of all securities
     covered by the Purchaser Registration Statement during the applicable
     period in accordance with the intended methods of disposition by the
     sellers thereof set forth in such prospectus as so supplemented.

2.3  Notify the selling holders promptly, and (if required by any such person)
     confirm such notice in writing, (i) when the Purchaser Registration
     Statement has been filed and when the same has become effective, (ii) of
     the issuance by the SEC or any other federal or state governmental
     authority of any stop order suspending the effectiveness of the Purchaser
     Registration Statement or the initiation of any proceedings for that
     purpose, and (iii) of the occurrence of any event which makes any statement
     made in the Purchaser Registration Statement or related prospectus or
     prospectus supplement, or any document incorporated or deemed to be
     incorporated therein by reference, untrue in any material respect or which
     requires the making of any changes in the Purchaser Registration Statement,
     prospectus, any prospectus supplement or any such document so that, in the
     case of the Purchaser Registration Statement, it will not contain any
     untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary to make the statements therein
     not misleading and, in the case of the prospectus or prospectus supplement,
     it will not contain any untrue statement of a material fact or omit to
     state any material fact required to be stated or necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading.

2.4  If requested by the holders holding a majority of the Consideration Shares
     being registered, (i) promptly incorporate in a prospectus supplement or
     post-effective amendment such information as such holders agree should be
     included therein and (ii) make all required filings of such prospectus
     supplement or such post-effective amendment as soon as practicable after
     the Purchaser has received notification of the matters to be incorporated
     in such prospectus supplement or post-effective amendment; provided,
     however, that the Purchaser will not be required to take any actions under
     this Section 2.4 that are not, in the opinion of independent counsel
     retained by the Purchaser, in compliance with applicable law.

                                     -48-
<PAGE>

2.5  Deliver to each selling holder, without charge, as many copies of the
     prospectus or prospectuses relating to such Consideration Shares (including
     each preliminary prospectus) and any amendment or supplement thereto as
     such persons may reasonably request; and the Purchaser hereby consents to
     the use of such Prospectus or each amendment or supplement thereto by each
     of the selling holders in connection with the offering and sale of the
     Consideration Shares covered by such prospectus or any amendment or
     supplement thereto.

2.6  To register or qualify or cooperate with the selling holders in connection
     with the registration or qualification (or exemption from such registration
     or qualification) of such Consideration Shares for offer and sale under the
     securities or blue sky laws of such jurisdictions within the United States
     as any seller reasonably requests in writing; use all reasonable efforts to
     keep such registration or qualification (or exemption therefrom) effective
     during the period the Purchaser Registration Statement is required to be
     kept effective and do any and all other acts or things necessary or
     advisable to enable the disposition in each such jurisdiction of the
     Consideration Shares covered by the Purchaser Registration Statement;
     provided, however, that the Purchaser will not be required to (i) qualify
     to do business in any jurisdiction in which it is not then so qualified or
     (ii) take any action that would subject it to service of process in any
     such jurisdiction in which it is not then so subject.

2.7  Upon the occurrence of any event contemplated by Section 2.3(iii) hereof,
     prepare and file a supplement or post-effective amendment to the Purchaser
     Registration Statement or a supplement to the related prospectus or any
     document incorporated therein by reference or any other required document
     so that, as thereafter delivered to the purchasers of the Consideration
     Shares being sold thereunder, such prospectus will not contain an untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary to make the statements therein, in light of
     the circumstances under which they were made, not misleading.

2.8  The Purchaser may require each seller of Consideration Shares as to which
     any registration is being effected to furnish to the Purchaser such
     information regarding the distribution of such Consideration Shares as the
     Purchaser may, from time to time, reasonably request in writing in order to
     provide adequate disclosure in the Purchaser Registration Statement and the
     Purchaser may exclude from such registration the Consideration Shares of
     any seller who unreasonably fails to furnish such information within a
     reasonable time after receiving such request.

3.   Registration Expenses.

     All fees and expenses incident to the performance of or compliance with the
     terms of this Schedule 2 by the Purchaser will be borne by the Purchaser.
     Such fees and expenses will include, without limitation, (i) all
     registration and filing fees (including, without limitation, fees and
     expenses for compliance with securities or "blue sky" laws), (ii) printing
     expenses (including, without limitation, expenses of printing certificates
     of Consideration Shares in a form eligible for deposit with The Depository
     Trust Company and of printing a reasonable number of prospectuses and
     prospectus supplements if the printing thereof is requested by the holders
     of a majority of the Consideration Shares participating in the offering),
     (iii) messenger, telephone and delivery expenses, (iv) fees and
     disbursements of counsel for the Purchaser, (v) fees and disbursements of
     all independent certified public accountants of Purchaser and (vi) fees and
     expenses of all other persons retained by the Purchaser. In addition, the
     Purchaser will pay its internal expenses (including, without limitation,
     all salaries and expenses of its officers and employees performing legal or
     accounting duties), the expenses of any annual audit, the fees and expenses
     incurred in connection with the listing of the securities to be registered
     on any securities exchange on which similar securities issued by the
     Purchaser are then listed and the fees and expenses of any person,
     including special experts, retained by the Purchaser. In no event, however,
     will the Purchaser be responsible for any selling commission with respect
     to any sale of Consideration Shares pursuant to this Agreement, and the
     holders shall be responsible on a pro rata basis for any taxes of any kind
     (including, without limitation, transfer taxes) with respect to any
     disposition, sale or transfer of Consideration Shares and for any legal,
     accounting and other expenses incurred by them in connection with any
     offering of Consideration Shares hereunder.

4.   Indemnification.

4.1  Indemnification by the Purchaser. The Purchaser will indemnify and hold
     harmless each holder of Consideration Shares registered pursuant to this
     Agreement, the officers, directors, agents and employees of each of them,
     each person who controls such a holder (within the meaning of Section 15 of
     the Securities Act or Section 20 of the Exchange Act) and the officers,
     directors, agents and employees of any such controlling person, from and
     against all losses, claims, damages, liabilities, costs (including, without
     limitation, reasonable attorneys' fees and expenses, and the costs incurred
     in connection with defending any investigation) and expenses (collectively,
     "Losses"), arising out of or based upon any untrue or alleged untrue
     statement of a material fact contained in the Purchaser Registration
     Statement, prospectus or form of prospectus or in any amendment or
     supplement thereto or in any preliminary prospectus, or arising out of or
     based upon any omission or alleged omission to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading, except insofar as the same are based solely upon
     information furnished in writing to the Purchaser by such holder expressly
     for use therein.

4.2  Indemnification by Holders. In connection with the offering in which a
     holder is participating, such holder will furnish to the Purchaser in
     writing such information as the Purchaser may reasonably request for use in
     connection with the Purchaser Registration Statement, prospectus or any
     amendment or supplement thereto or preliminary prospectus and will
     indemnify, to the fullest extent permitted by law, the Purchaser, its
     respective directors and officers, agents and employees, each person who
     controls the Purchaser (within the meaning of Section 15 of the Securities
     Act and Section 20 of the Exchange Act), and the directors, officers,
     agents or employees of such controlling persons, from and against all
     Losses arising out of or based upon any untrue statement of a material fact
     contained in any Registration Statement, prospectus or any amendment or
     supplement thereto or preliminary prospectus or arising out of or based
     upon any omission of material fact required to be stated therein or
     necessary to make the statements therein not misleading, to the extent, but
     only to the extent, that such untrue statement or omission is contained in
     any information so furnished in writing by such holder to the Purchaser
     expressly for use in such Registration Statement, prospectus or any
     amendment or supplement thereto or preliminary prospectus.

4.3  Conduct of Indemnification Proceedings. If any person shall become entitled
     to indemnity hereunder (an "Indemnified Party"), such Indemnified Party
     shall give prompt notice to the party from which such indemnity is sought
     (the "Indemnifying Party") of any claim or of the commencement of any
     action or proceeding with respect to which such Indemnified Party seeks
     indemnification or contribution pursuant hereto; provided, however, that
     the failure to so notify the Indemnifying Party will not relieve the
     Indemnifying Party from any obligation or liability except to the extent
     that the Indemnifying Party has been prejudiced materially by such failure.
     In case any such action is brought against an Indemnified Party, unless in
     such Indemnified Party's reasonable judgment a conflict of interest between
     such Indemnified and Indemnifying Parties may exist in respect of such
     claim, the Indemnifying Party will be entitled to participate in and,
     jointly with any other Indemnifying Party similarly notified, to assume the
     defense thereof, to the extent that it may wish, with counsel reasonably
     satisfactory to such Indemnified Party, and after notice from the
     Indemnifying Party to such Indemnified Party of its election so to assume
     the defense thereof, the Indemnifying Party will not be liable to such
     Indemnified Party for any legal or other expenses subsequently incurred by
     the latter in connection with the defense thereof, unless in such
     Indemnified Party's reasonable judgment a conflict of interest between such
     Indemnified and Indemnifying Parties arises in respect of such claim after
     the assumption of the defense thereof, and the Indemnifying Party will not
     be subject to any liability for any settlement made without its consent
     (which consent shall not be unreasonably withheld). The Indemnifying Party
     will not consent to entry of any judgment or enter into any settlement or
     otherwise seek to terminate any action or proceeding in which any
     Indemnified Party is or could be a party and as to which indemnification or
     contribution could be sought by such Indemnified Party under this Section
     4, unless such judgment, settlement or other termination includes as an
     unconditional term thereof the giving by the claimant or plaintiff to such
     Indemnified Party of a release, in form and substance satisfactory to the
     Indemnified Party, from all liability in respect of such claim or
     litigation for which such Indemnified Party would be entitled to
     indemnification hereunder. An Indemnifying Party who is not entitled to, or
     elects not to, assume the defense of a claim will not be obligated to pay
     the fees and expenses of more than one counsel in any single jurisdiction
     for all parties indemnified by such Indemnifying Party with respect to such
     claim, unless in the reasonable judgment of any Indemnified Party a
     conflict of interest may exist between such Indemnified Party and any other
     of such Indemnified Parties with respect to such claim, in which event the
     Indemnifying Party shall be obligated to pay the fees and expenses of such
     additional counsel or counsels as may be reasonably necessary.
     Notwithstanding anything else to the contrary herein, and without limiting
     the rights set forth above, in any event any party will have the right to
     retain, at its own expense, counsel with respect to the defense of a claim.

4.4  Contribution. If the indemnification provided for in this Section 4 is
     unavailable to an Indemnified Party in respect of any Losses or is
     insufficient to hold such Indemnified Party harmless, then each applicable
     Indemnifying Party, in lieu of indemnifying such Indemnified Party, will,
     severally but not jointly, contribute to the amount paid or payable by such
     Indemnified Party as a result of such Losses, in such proportion as is
     appropriate to reflect the relative fault of the Indemnifying Party or
     Indemnifying Parties, on the one hand, and such Indemnified Party, on the
     other hand, in connection with the actions, statements or omissions that
     resulted in such Losses as well as any other relevant equitable
     considerations. The relative fault of such Indemnifying Party or
     Indemnifying Parties, on the one hand, and such Indemnified Party, on the
     other hand, will be determined by reference to, among other things, whether
     any action in question, including any untrue or alleged untrue statement of
     a material fact or omission or alleged omission of a material fact, has
     been taken or made by, or related to information supplied by, such
     Indemnifying Party or Indemnified Party, and the parties'

                                     -50-
<PAGE>
 

     relative intent, knowledge, access to information and opportunity to
     correct or prevent such action, statement or omission. The amount paid or
     payable by a party as a result of any Losses will be deemed to include any
     legal or other fees or expenses incurred by such party in connection with
     any action or proceeding.

     The parties hereto agree that it would not be just and equitable if
     contribution pursuant to this Section 4.4 were determined by pro rata
     allocation or by any other method of allocation that does not take into
     account the equitable considerations referred to in the immediately
     preceding paragraph. No person guilty of fraudulent misrepresentation
     (within the meaning of Section 11(f) of the Securities Act) will be
     entitled to contribution from any person who was not guilty of such
     fraudulent misrepresentation.

     Notwithstanding the provisions of this Section 4, an Indemnifying Party
     that is a selling holder will not be required to pay any amount in respect
     of indemnity hereunder or contribute any amount hereunder in excess of the
     amount by which the total price at which the Consideration Shares sold by
     such Indemnifying Party were offered to the public exceeds the amount of
     any damages which such Indemnifying Party has otherwise been required to
     pay by reason of such untrue or alleged untrue statement or omission or
     alleged omission.

     The indemnity, contribution and expense reimbursement obligations of the
     Purchaser hereunder will be in addition to any liability the Purchaser may
     otherwise have hereunder or otherwise. The provisions of this Section 4
     will survive so long as Consideration Shares remain outstanding,
     notwithstanding any permitted transfer of the Consideration Shares by any
     holder thereof or any termination of this Agreement.

5.   Transfer of Rights

5.1  In connection with a transfer of Purchaser's Ordinary Shares other than
     pursuant to the Purchaser Registration Statement or Rule 144, the rights of
     each holder of Consideration Shares under this Schedule 2 may be assigned
     by each holder (i) if the holder is a corporation (other than a publicly-
     held corporation), to a shareholder or shareholders of such holder, (ii) if
     the holder is a partnership (other than a publicly-held partnership), to a
     partner or partners of that partnership, (iii) if the holder is an
     individual, to a family member of that holder, (iv) upon the death of the
     holder, to the heirs of the holder by virtue of the holder's will or the
     laws of descent and distribution, (v) if the holder is a corporation or a
     partnership, to any person into or with which the holder is merged or
     consolidated or to which the holder sells all or substantially all of its
     assets, (vi) in connection with a bona fide pledge of Consideration Shares,
     to the pledgee or (vii) to an entity controlled by or under common control
     with the holder. No such assignment of rights shall be effective until
     Purchaser shall receive written notice thereof in the manner specified in
     the Agreement. In the event of any such permitted assignment, the assignee
     shall be entitled to further assign as permitted under this Section 5.

              terminate or modify, or result in the creation of any material
              Encumbrance under any agreement, licence or other instrument or
              result in a material breach of any order, judgment or decree of
              any Court, governmental agency or regulatory body to which the
              Company is a party or by which the Company or any of its assets is
              bound.

6.3  Arrangements with Connected Persons etc.

       6.3.1  There is no indebtedness (actual or contingent) nor any indemnity,
              guarantee or security arrangement between any Group Company or any

              director or any current or former consultant of any Group Company
              or any person connected with any of such persons.

       6.3.2  No Group Company is a party to any contract, arrangement or 
              understanding with any current or former employee, current or
              former director or any current or former consultant of any Group

       6.3.3  With the exception of the contracts and arrangements details of

              existing contracts or arrangements between or involving any Group
              Company and any of the Vendors and/or any director of any Group
              Company and/or any person connected with any of them other than on
              normal commercial terms in the ordinary course of business.

6.4  Contracts

No Group Company is party to any long-term commitments, contracts or
arrangements or any such not wholly on an arm's length basis in the ordinary
course of business. For these purposes, a long-term contract, commitment or
arrangement is one which is unlikely to have been fully performed in accordance
with its terms more than six months after the date it was entered into or

<PAGE>
 
       7.7.2  The Final Salary Scheme is sufficiently and effectively funded on
              an on-going basis using the actuarial assumptions which were used

              currently, prospectively and contingently payable under the Final
              Salary Scheme at least to the extent to which they have accrued at
              the date of this Agreement.

              Scheme on retirement, death or leaving service and each Group
              Company may terminate any obligation it may have to contribute to

              any agreement or arrangement with the member.

       7.7.5  No power or discretion to augment benefits under any of the 
              Schemes has been exercised in favour of an Employee in the last 5
              years as there is no obligation in respect of any employee to do
              so.

7.8  Disclosed Schemes - compliance

       7.8.1  The Schemes are Approved and none of the Vendors is aware of any
              circumstances which might give the Board of Inland Revenue reason
              to withdraw Approval.

       7.8.2  The Schemes are contracted-out schemes for the purposes of the
              Pension Schemes Act 1993 and have been administered in accordance
              with the contracting-out requirements of Part III of that Act.

       7.8.3  The Disclosed Schemes and the Executive Pension Plan have at all
              times been operated in accordance with their governing
              documentation and in accordance with all applicable laws and
              regulatory requirements including, without limitation, the
              requirements of Article 119 of the Treaty of Rome relating to
              equal benefits and admission to membership (except insofar as it
              relates to GMPs) and the requirements of the Pensions Act 1995.

The rules of and a current benefit statement for the Executive Pension Plan have
been disclosed to the Purchaser. The Executive Pension Plan is a defined
contribution scheme, of which John Charman is the only member. No person is
principal employer of the Executive Pension Plan other than CUAL, and no person
is a participating employer in the Executive Pension Plan other than CUAL. There
are no circumstances in which the liability (whether actual or contingent) of
CUAL (or any other Group Company) to the Executive Pension Plan could (in
aggregate) exceed 40 per cent. of the basic 

                                      -62-
<PAGE>
 
annual salary of John Charman. Other than in the ordinary course of business,
there are no contributions to the Executive Pension Plan which have fallen due
but are unpaid.

8  Taxation Matters

8.1  Returns, Information and Clearances

       8.1.1  All returns, computations, notices and information which are or 
              have been required to be made or given by each Group Company for
              any Taxation purpose (i) have been made or given within the
              requisite periods and on a proper basis and are up-to-date and

              of any dispute with the Inland Revenue or other Taxation
              authorities.

       8.1.2  Each Group Company is in possession of sufficient information to
              enable it to compute its liability to Taxation insofar as it
              depends on any Transaction occurring on or before Completion.

8.2  Taxation Claims, Liabilities and Reliefs

       8.2.1  There are set out in the Vendors' Disclosure Letter, with express
              reference to this paragraph, details of all matters relating to
              Taxation in respect of which each Group Company (either alone or
              jointly with any other person) has, or at Completion will have, an
              outstanding entitlement to make: any claim (including a
              supplementary claim) for relief; any election, including an
              election for one type of relief, or one basis, system or method of
              Taxation, as opposed to another; any appeal or further appeal
              against an assessment to Taxation; any application for the
              postponement of, or payment by instalments of, Taxation; or to
              disclaim or require the postponement of any allowance or relief.
              Such details are reasonably sufficient to enable the Purchaser to
              procure that any time limit to such entitlement expiring within
              six months after Completion can be met.

       8.2.2  No relief (whether by way of deduction, reduction, set-off, 
              exemption, postponement, roll-over, hold-over, repayment or
              allowance or otherwise) from, against or in respect of any
              Taxation has been claimed and/or given to any Group Company which
              could or might be effectively withdrawn, postponed, restricted,
              clawed back or otherwise lost as a result of any act, omission,
              event or circumstance arising or occurring in the ordinary course

nowhere else at all times since its incorporation and will be so resident at
Completion.

8.5  Acquisitions from Members of the same Group

The entry into or Completion of this Agreement will not result in any profit or
gain being deemed to accrue to any Group Company for Taxation purposes, whether
pursuant to Section 179 of the Taxation of Chargeable Gains Act 1992 (TCGA) or
otherwise.

8.6  Replacement of Business Assets

No claim has been made under Section 152, 153, 154 or 175 TCGA or any other
section which would affect the amount of any gain accruing or being treated as
accruing on a disposal of an asset of any Group Company.

8.7  Base Values and Costs of Acquisition

If each of the assets (other than trading stock) or the plant and machinery
taken as a whole of each Group Company was disposed of for a consideration equal
to the book value of that asset or, as appropriate, plant and machinery in, or
adopted for the purpose of, the Audited Accounts, no liability to corporation
tax on chargeable gains or balancing charge under the Capital Allowances Act
1990 not fully provided for in the Audited Accounts would arise; and, for the
purpose of determining corporation tax on chargeable gains, there shall be
disregarded any relief and allowances available to the Group Company concerned
other than amounts falling to be deducted under Section 38 TCGA.

8.8  Rebasing

No Group Company has made a disposal to which Section 35 TCGA applies.

8.9  PAYE and National Insurance

Each Group Company has properly operated the PAYE and National Insurance
contributions systems by making such deductions as are required by law from all
payments made or deemed to be or treated as made by it or on its behalf, and by
duly accounting to the Inland Revenue for all sums so deducted and for all other
amounts for which it is required to account under the PAYE and National
Insurance contributions systems.

8.10  Depreciatory Transactions and Value Shifting

No asset owned by any Group Company has at any time since its acquisition by
that or any other Group Company or any company which has at any time been a
member of a group (as defined from time to time for any Taxation purpose) of
which the Group Company has at any time been a member 

                                      -64-
<PAGE>
 
been subjected to a reduction in value such that any allowable loss arising on
its disposal is likely to be reduced or eliminated or any chargeable gain
arising on its disposal is likely to be increased.

8.11  Value Added Tax (VAT)

       8.11.1  Each Group Company has complied fully with all statutory 
               requirements, orders, provisions, directions or conditions
               relating to VAT, including (for the avoidance of doubt) the terms
               of any agreement reached with the Commissioners of Customs &
               Excise.

       8.11.2  No Group Company is a "developer" as defined in paragraph 5 
               Schedule 10 Value Added Tax Act 1994 in relation to any building
               or work within paragraph 5(2) of that Schedule or any
               reconstructions, enlargements or extensions within paragraph 5(8)

June 4, 1998



To The Board of Directors and Shareholders of Tarquin Plc

We have audited the accompanying consolidated balance sheets of Tarquin plc and
subsidiaries as of December 31, 1997 and 1996, and the related consolidated
statements of income, of changes in stockholders' equity and of cash flows for
each of the three years in the period ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing standards
of the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Tarquin plc and its
subsidiaries at December 31, 1997 and 1996, and the results of their operations,
their changes in stockholders' equity and their cash flows for each of the three
years in the period ended December 31, 1997, in conformity with generally
accepted accounting principles of the United States of America.

     Notes to the Consolidated Financial Statements

1.   Summary of significant accounting policies

 (a) Basis of presentation, principles of consolidation and nature of operations

     These accounts have been prepared under generally accepted accounting
     principles of the United States of America ("U.S. GAAP"), using the Group's
     functional currency which is U.S. dollars.

     The Company is a worldwide speciality lines insurer and reinsurer. The
     principal activity of Tarquin plc is that of a corporate underwriting
     member of Lloyd's of London ("Lloyds"), being the sole member of Syndicate
     2488, and of a Lloyd's managing agent for syndicates 2488 and 488.
     Syndicate 2488 commenced underwriting for the 1995 year of account with a
     capacity of $264 million which was increased to $313.5 million for the 1996
     year of account and to $330 million for the 1997 year of account.

     The consolidated financial statements include the accounts of Tarquin plc,
     a holding company, its wholly owned subsidiaries, Tarquin Underwriters
     Limited, a corporate member of Lloyd's, and its dedicated corporate
     syndicate, 2488. The consolidated financial statements also include the
     accounts of Charman Underwriting Agencies Limited, a Lloyd's managing
     agent, and its holding company, Charman Group Limited. Tarquin plc and its
     subsidiaries are collectively referred to as "Tarquin" or "the Company".
     All significant inter-company transactions and balances have been
     eliminated. The 1995 income statement includes the results of the Company's
     operations since the purchase of Charman Group Limited by Tarquin plc,
     which occurred on November 30, 1994. Accordingly, the results of operations
     in the 1995 income statement are for 13 months, however the 1994 results
     are immaterial to the results of that period.
     
     The preparation of financial statements requires management to make
     estimates and assumptions that affect the reported amounts of assets and
     liabilities and disclosure of contingent asset and liabilities at the date
     of the financial statements and the reported amounts of revenues and claims
     and expenses during the reporting period. Actual results could differ from
     those estimates.

     Accounting Policies

 (b) Underwriting results

     Underwriting results are recognised on an annual accounting basis, which
     requires estimates for underwriting years which have not yet closed under
     the Lloyd's three year accounting convention.

 (c) Premiums and unearned premiums reserves

     Premiums are accounted for in the period in which the risk commences.
     Unearned premiums relating to risks in future periods of account are
     calculated on a pro-rata basis over the period of the risk.

 (d) Outstanding claims, losses and loss adjustment expenses

     Claims and claim adjustment expense reserves represent estimated provision
     for both reported and unreported claims incurred and related expenses. The
     reserves are adjusted regularly based on experience.


                                                                          Page 8
<PAGE>
 
     TARQUIN PLC
     
     Notes to the Consolidated Financial Statements

1.   Summary of significant accounting policies (continued)

     In determining claims and claim adjustment expense reserves, the Company
     carries out a continuous review of its overall position, its reserving
     techniques and its reinsurance. These reserves represent the estimated
     ultimate cost of all incurred claims and claim adjustment expenses. Since
     the reserves are based on estimates, the ultimate liability may be more or
     less than such reserves. The effects of changes in such estimated reserves
     are included in the results of operations in the period in which the
     estimates are changed. Such changes may be material to the results of
     operations and could occur in a future period.
     
 (e) Amounts due from intermediaries

     Amounts due from intermediaries are amounts of premium which, it is
     estimated, are due to the syndicate from policyholders. These amounts of
     premium are estimated based on underwriting signings and brokers estimates,
     and are presented gross of brokerage and commissions. These premium
     estimates are adjusted periodically to reflect current experience.
     
 (f) Accrued profit commission

     The company earns fees and profit commissions from managing Syndicate 488.
     Under the Lloyd's three year accounting convention, profit commission is
     only due and payable upon the closure of an underwriting account. Estimated
     amounts of profit commission, based on underwriting results, are therefore
     accrued in the year to which they relate. Accrued profit commissions are
     adjusted to reflect current experience, and are included within other
     income in the revenue account and other assets in the balance sheet.

 (g) Reinsurance receivables

     Amounts receivable from reinsurers are estimated and recorded in a manner
     consistent with the claim liability associated with the reinsured business.
     The Company evaluates and monitors the financial condition of its
     reinsurers to minimize its exposure to significant losses from reinsurer
     insolvencies.

 (h) Deferred policy acquisition costs

     Commissions and premium taxes, which vary with and are primarily related to
     the production of new business, are deferred and amortised pro rata over
     the contract periods in which the related premiums are earned. Deferred
     acquisition costs are reviewed to determine if they are recoverable from
     future income, and if not, are charged to expense. All other acquisition
     expenses are charged to operations as incurred.
     
 (I) Investments

     Fixed maturities and equity securities

     Fixed maturities include bonds, notes and redeemable preferred stocks.
     Equity securities consist solely of common stock. Fixed maturities and
     equity securities are classified as "available for sale" and are reported
     at fair value, with unrealised investment gains and losses, net of income
     taxes, charged or credited directly to stockholders' equity. Fixed
     maturities and equity securities are valued based upon quoted market
     prices. Investment income is presented net of investment expenses.

                                                                          Page 9

     Notes to the Consolidated Financial Statements

1.   Summary of significant accounting policies (continued)

     Cash and cash equivalents
     Cash and cash equivalents include cash on hand and highly liquid debt
     instruments purchased with an original maturity of three months or less.

     In the normal course of business, the Company enters into transactions
     involving various types of financial instruments, including debt
     investments such as fixed maturities and equity securities. These
     instruments involve credit risk and also may be subject to risk of loss due
     to interest rate fluctuation. The Company evaluates and monitors each
     financial instrument individually and, when appropriate, obtains collateral
     or other security to minimise losses.

 (j) Realised investment gains and losses

     Realised investment gains and losses are included as a component of pre-tax
     revenues based upon specific identification of the investments sold on the
     trade date. Other than temporary declines in the market value of
     investments are included in realised investment losses.
     
 (k) Goodwill and other intangible assets

     Goodwill is amortised on a straight-line basis over a 25 year period.

     The Company has purchased participation rights on Syndicate 488 in the
     Lloyd's capacity auctions of 1996 and 1997 and in a special offer to Names
     in 1997 to participate in all future underwriting years. The costs of
     capacity purchases have been capitalised and are written off over three
     years on a straight line basis against future underwriting income
     commencing in the first underwriting year of participation.
     
     The carrying amount of intangible assets is reviewed regularly for
     indications of other than temporary impairment in value. Impairments would
     be recognised in operating results if a permanent diminution in value has
     deemed to have occurred.
     
 (l) Income taxes

     Tarquin is a UK tax registered group which is liable for UK income tax on
     its operating profits. In addition, syndicate 2488 is liable for U.S.
     Federal income tax on its underwriting profits which are deemed to have
     arisen in the U.S., which may be offset against UK taxes when calculating
     total tax liabilities. Deferred income taxes are generally recognised when
     assets and liabilities have different values for financial statement and
     tax reporting purposes. These differences result primarily from tax exempt
     interest income and disallowable interest expense.
     
 (m) Foreign exchange

     Amounts expressed in foreign currencies are translated into U.S. dollars.
     Assets and liabilities denominated in sterling are translated into U.S.
     dollars generally using current rates of exchange and the related
     translation adjustments are recorded as a separate component of
     shareholders equity net of any related taxes. Income statement amounts
     expressed in sterling are translated using average exchange rates. Exchange
     gains and losses resulting from foreign currency transactions are recorded
     in other income. The consolidated statement of income contains an aggregate
     transaction gain/(loss) of $170,736, $4,256,199 and ($870,565) in 1997,
     1996 and 1995, respectively.

                                                                         Page 10

1.    Summary of significant accounting policies (continued)

  (n) Fixed assets

      Leasehold improvements, equipment and motor vehicles are stated at cost,
      less accumulated depreciation and amortisation. Depreciation is provided
      using the straight-line or accelerated method over the estimated useful
      lives of the related assets which generally range from 2 to 5 years.
      Amortisation of leasehold improvements is provided using the straight-line
      method over the term of the lease.

2.    Significant transactions

      During 1996 Lloyd's successfully initiated it's Reconstruction and Renewal
      Plan ("R&R"), establishing a dedicated run-off company, Equitas
      Reinsurance Limited to assume the liabilities of the 1992 and prior
      underwriting years of all syndicates. As part of R&R, Managing Agents were
      required by Lloyd's to pay a one time contribution to Lloyd's. The
      contribution payable by the Company was based on the early release of
      profit commission from the 1995 underwriting year and amounted to
      $7,652,129. This was recognised as an expense in 1996.

      The Company held no derivative financial instruments in its investment
      portfolio during the three year period ended December 31, 1997.

      As of December 31, 1997, the Company had no concentration of investments
      in a single investee exceeding 10% of shareholders' equity, except for UK
      and U.S. government issues.

4.    Fair value disclosures of financial instruments

      SFAS No 107, "Disclosures about Fair Value of Financial Instruments",
      requires disclosure of fair value information about certain financial
      instruments (insurance contracts and taxes are excluded) for which it is
      practicable to estimate such values, whether or not these instruments are
      included in the balance sheet. The fair values presented for certain
      financial instruments are estimated which, in many cases, may differ
      significantly from the amounts which could be realised upon immediate
      liquidation. In cases where market prices are not available, estimates of
      fair value are based on discounted cash flow analyses which utilise
      current interest rates for similar financial instruments which have
      comparable terms and credit quality.

      The following methods and assumptions were used to estimate the fair value
      of each class of financial instruments:

      Cash and Cash Equivalents

      For these short-term investments, the carrying amount approximates fair
      value.

      Fixed maturities

      Fair values are based on quoted market prices.

                                                                         Page 14

4.    Fair value disclosures of financial instruments (continued)

      Equity Securities
      Fair values are based on quoted market prices.
      Long Term Debt
      Fair values are estimated by discounting future contractual cash flows
      using the current rates at which the Company could borrow.

      The estimated fair values of the financial instruments as of December 31,
      were as follows:

</TABLE>

      Deposits made to the Joint Asset Trust Fund are calculated by reference to
      the Syndicates' gross liabilities in respect of U.S. situs surplus lines
      and reinsurance business (i.e. risks geographically located in the U.S.).
      The fund is a requirement for the Syndicate to write this type of business
      in the U.S.

      The Syndicate is required to lodge a deposit with Additional Securities
      Limited in order to comply with the statutory requirements of various
      countries in which it does business.

      Kentucky is the only state in the U.S. where all Lloyd's syndicates are
      licensed to write insurance business. With effect from January 1, 1996,
      all underwriting members of Lloyd's conducting licensed Kentucky business
      are required to maintain a joint asset trust fund in Kentucky to meet
      certain capital and surplus requirements. Each syndicate year of account
      has also been required to establish trust funds in respect of the
      liabilities for the Kentucky licensed business written by its Names. These
      liabilities based trust funds are adjusted quarterly according to a
      liabilities calculation agreed to with the Kentucky Insurance Department.

6.    Fixed assets

      July 31, 1997. Names were offered 16.5 cents for every $1.65 of capacity
      and a total capacity of $70,361,948 was acquired.

8.    Reinsurance

      In the normal course of business, the Company seeks to reduce the loss
      that may arise from catastrophes or other events that cause unfavourable
      underwriting results by reinsuring certain levels of risk in various areas
      of exposure with other Lloyd's Syndicates, insurance companies or
      reinsurers. Reinsurance transactions are accounted for in accordance with
      the provisions of SFAS No. 113.

      Amounts recoverable from reinsurers are estimated in a manner consistent
      with the claim liability associated with the reinsured policy. Reinsurance
      contracts do not relieve the Company from its obligations to
      policyholders. Failure of reinsurers to honour their obligations could
      result in losses to the Company; consequently, allowances are established
      for amounts deemed uncollectible. The Company determines the appropriate
      amount of reinsurance based on market conditions (including the
      availability and pricing of reinsurance). The company also believes that
      the terms of its reinsurance contracts are consistent with industry
      practice in that they contain standard terms with respect to lines of
      business covered, limit and retention, arbitration and occurrence. Based
      on its review of its reinsurers' financial statements and reputations in
      the reinsurance marketplace, the Company believes that its reinsurers are
      financially sound.

      The Company is subject to credit concentration risk with respect to
      reinsurance ceded. The Company's three largest reinsurers accounted for
      approximately 69.7% and 63.7% of reinsurance receivables on outstanding
      claims, losses and loss adjustment expenses at December 31, 1997 and 1996,
      respectively. See Note 17 for a discussion of litigation in which the
      company is involved with respect to its reinsurance programs.

      The effect of reinsurance on premiums written was as follows:

10.   Reconciliation of net liability for claims and adjustment expenses

      The Company regularly updates its reserve estimates as new information
      becomes available and further events occur which may impact the resolution
      of unsettled claims. As the Company has not previously prepared accounts
      on an annual basis, nor estimated their liability for claims and
      adjustment expenses on an annual basis, these accounts reflect no prior
      year development. The table below provides a reconciliation of the
      beginning and ending reserves for unpaid losses and loss adjustment
      expenses (LAE) for the years ended December 31, as follows:

      UK corporation tax is payable at the rate of 33% on group trading profits
      earned in calendar years 1995 and 1996. The corporation tax rate was
      reduced to 31% for profits earned after April 1, 1997, therefore the
      trading profits of 1997 are subject to two different rates of taxation,
      depending on when they were realised. Tax on the underwriting profits of
      Tarquin Underwriters Limited is not payable until one year after the
      closure of the underwriting year to which it relates. An underwriting
      account will normally close after three years.

      Tarquin Underwriters Limited is liable for U.S. Federal Income tax (USFIT)
      on underwriting profits determined to have arisen from U.S. underwriting.
      Under the existing UK double taxation rules, this USFIT can be offset
      against the UK tax payable when the underwriting year closes. Included in
      the figure of other assets as at December 31, 1997 is USFIT paid of
      $2,004,135, $2,104,051 and $2,334,544 in respect of the 1997, 1996 and
      1995 underwriting years, respectively.

      No UK tax computations for the Company have been agreed to by the Revenue
      since the inception of the Company.

      Tax on the profit commission receipts of Charman Underwriting Agencies
      Limited is not payable until one year after receipt which is after the
      closure of the underwriting year to which it relates.

      The income taxes attributable to the consolidated results of operations
      are different from the amounts determined by multiplying income before
      income taxes by the statutory income tax rate. The sources of the
      difference were as follows:

      Notes to the Consolidated Financial Statements

13.   Capital structure (continued)

      Earn-out provision

      Upon the first occurrence of an Exit Event, which is defined as the
      earlier of December 31, 1999, an initial public offering or sale of the
      Company, additional shares may become available which may be distributed
      at the sole discretion of Charman Trustees Limited, an indirectly but
      wholly owned subsidiary of Tarquin plc. The amount of additional shares to
      become available is based upon the internal rate of return of the "B"
      ordinary and "C" ordinary shares of the Company measured at the date of
      the Exit Event, but will not exceed 7% of the ordinary shares in issue
      immediately prior to the Exit Event. As these shares have not been granted
      to specific employees, no compensation expense has been recorded in these
      financial statements.

      Dividend Distribution Restrictions

      Charman Underwriting Agencies Limited is a Lloyd's managing agent. All
      Lloyd's managing agencies are subject to solvency provisions which place
      effective limits on the amounts of distributable profits. These limits are
      designed to ensure that the agencies retain sufficient funds to manage
      their businesses. Charman Underwriting Agencies Limited must maintain its
      level of net current assets (on a UK GAAP basis) at each balance sheet
      date so that it equals or exceeds 25% of the agency's recurring
      expenditure, after deducting certain expenses. The agency must also
      maintain its net assets (on a UK GAAP basis) at each balance sheet date so
      that they are equal to or greater than the higher of minimum qualifying
      capital (currently (Pounds)325,000) or .275% of aggregate syndicate
      allocated capacity. Charman Underwriting Agencies Limited can meet the
      solvency requirements from amounts of retained earnings as at December 31,
      1997 which means that post-tax earnings from that date onwards will be
      fully distributable subject only to changes in the solvency requirements.

14.   Pension plans

      The Company operates both a defined contribution scheme and a defined
      benefit scheme to provide benefits for the staff of Charman Underwriting
      Agencies Limited. Both schemes are fully insured.

      The defined benefit scheme is a final salary scheme contracted-out of the
      State Earnings Related Pensions Scheme under the provisions of the
      Pensions Schemes Act 1995. It is an exempt approved scheme under Chapter 1
      of part XIV of the Income and Corporation Taxes Act 1988 and is
      established and governed by a trust deed and rules which have been
      approved by the Occupational Pensions Board and the Pensions Schemes
      Office.

      Components of net pension expense for the years ended December 31 were as
      follows:

      Determination of the projected benefit obligation was based on a weighted
      average discount rate of 7.5% in 1997 and 6.5% in 1996, and the assumed
      long-term rate of return on plan assets was 9.0%. The actuarial present
      value of the projected benefit obligations was determined using assumed
      rates of increase in future compensation levels ranging from 5% to 6%.
      Plan assets are invested in a with profits deposit administration
      insurance contract.

      The company also has a defined contribution pension plan for its
      employees. This plan is a contracted-out money purchase scheme. The plan
      expense in 1997, 1996 and 1995 was $181,000, $162,000 and $146,000,
      respectively.

</TABLE>

      Charman Underwriting Agencies Limited charges the providers of capital on
      its two managed syndicates a fixed fee (based on syndicate capacity) which
      encompasses the managing agent's fee and syndicate expenses. This flat fee
      covers all normal expenses which managing agents, in accordance with best
      practice, are able to recover from a syndicate, including, but not limited
      to, staff and property costs, computer charges, travel and Lloyd's
      charges. Items not included are those which are incurred as a direct
      consequence of business transactions such as commissions, a 1.1% premium
      levy (on the 1997 account and onwards), claims adjusters and related legal
      fees, foreign exchange variances and overseas premium taxes. No further
      amount is charged to the syndicates provided that they close in the normal
      manner at the end of 36 months.

      For 1995, 1996 and 1997 the flat fee was 2.5% of capacity. This was
      increased in 1998 to 2.75% subject to a minimum aggregate fee of
      (Pounds)9,075,000 or approximately $15,000,000.

      Managed syndicates are charged a profit commission which is based on the
      underwriting profits of a closed underwriting account. Profit commission
      for the 1995, 1996 and 1997 accounts has been and will be charged at the
      rate of 15%. For the 1998 underwriting year this will be increased to
      17.5%.

      The amount of profit commission and management fee income from Syndicate
      488 was $11,526,000, $16,251,000 and $11,585,000 in 1997, 1996 and 1995,
      respectively. The amount of profit commission accrued at December 31, 1997
      and 1996 was $18,940,000 and $29,358,000, respectively.

      In addition, the Company has outstanding debt with Aeneas Venture
      Corporation, a related party. See Note 16 for further information on this
      related party debt.

       Loan - Bank of Boston

       The Bank of Boston advanced $15,370,000 to the Company on November 27,
       1995. Interest on the loan is payable at a rate of 1 1/2% per annum above
       LIBOR rates at one, three or six monthly intervals, at the Company's
       discretion. The loan is repayable in instalments of between 10% and 30%
       of the amount advanced with the last instalment being repayable on the
       earlier of seven days after the release to Charman Underwriting Agencies
       Limited of profit commission in respect of the 1997 underwriting year of
       account or June 30, 2000.

       This loan agreement contains covenants which limit the Company's ability
       to pay dividends and enter into certain transactions. Additionally, this
       loan agreement requires that the tangible net worth of the Company (under
       Lloyd's 3 year accounting rules) not be less than $46,200,000 from the
       period July 1, 1997 through June 30, 1998 and $88,020,000, from July 1,
       1998 onward.

       Related Party Loan - Aeneas Venture Corporation

       A loan of $35,172,000 was advanced to the company by Aeneas Venture
       Corporation, a company whose sole shareholder is the President and
       Fellows of Harvard University, on November 30, 1994. The President and
       Fellows of Harvard University are also the sole shareholder of Phemus
       Corporation which holds all of the US$1 "B" ordinary shares in the
       Company.

       Interest payable on the loan is calculated by two methods; a base rate of
       13% per annum is payable annually in arrears; an additional rate of up to
       12% will become payable on the "Final Repayment Date" which is the
       earlier of:

       1.  the date of an initial public offering ("IPO");
    
       2.  the date of a sale of shares of Tarquin plc to a third party or
           parties who are not connected persons with any of the existing
           shareholders of the company which, when aggregated with all previous
           such sales comprises more than 50% of the shares subscribed for by
           the investors;

       3.  the seventh anniversary of the date of the original loan agreement
           (which was December 22, 1994); or
    
       4.  in the absence of an IPO or sale prior to such seventh anniversary,
           such later date, not exceeding 36 months from the date of the seventh
           anniversary as the lender may determine.
      
                                                                         Page 27

     TARQUIN PLC

     Notes to the Consolidated Financial Statements

16.  Debt (continued)

     The additional rate payable will be determined by a formula which is
     dependent on the internal rate of return which accrues to "B" and "C" US$1
     ordinary shares upon the "Final Repayment Date".

     The additional interest amount has been accrued at the full 12% as an
     evaluation of the internal rate of return has indicated that it is in
     excess of the amount which would cause the full 12% to become payable.
     However, no amount is payable until the "Final Repayment Date". Additional
     interest expense of $4,220,640 has been recognised in each of the three
     years ended December 31, 1997.

     This loan agreement also contains covenants which limit the Company's
     ability to pay dividends and enter into certain transactions.

17.  Contingencies

     The terms of certain reinsurance contracts for Syndicate 2488, for which
     Tarquin Underwriters Limited is the sole capital provider, are being
     disputed by reinsurers. Current legal advice confirms the contracts are
     fully enforceable and, therefore, no provision has been made. As at
     December 31, 1997, the amounts due under the contracts in question was
     $10,768,870 and reinsurance receivables on unpaid losses and IBNR was
     $30,578,736.

PRO FORMA FOOTNOTES WITH RESPECT TO THE CAT ACQUISITION


(1)  Reflects the acquisition by CAT of Hamilton Services Limited for $1.6
     million immediately prior to the CAT Acquisition. This acquisition was
     accounted for under the purchase method of accounting.

(2)  Under the terms of the Stock purchase Agreement, dated 25 March, 1998,
     between ACE, CAT and the Shareholders of CAT (the "Stock Purchase
     Agreement"), CAT's ownership in Enterprise Reinsurance Holdings Corporation
     ("Enterprise") was distributed to CAT's existing shareholders prior to the
     acquisition of CAT by the Company in return for CAT shares. This adjustment
     reflects the disposition of Enterprise for $69 million. The shares received
     by CAT were retired.

(3)  As part of the financing of the acquisition, ACE borrowed $385 million of
     short-term bank borrowings from its undrawn credit facility established in
     December 1997, and from cash on hand. The interest rate on the short-term
     borrowing was approximately 6%.
     
(4)  Under the terms of the Stock Purchase Agreement, ACE paid a total purchase
     price of approximately $691 million (the total aggregate purchase of $711
     million includes an estimate of CAT earnings for first quarter of calendar
     1998 of $20 million). ACE also incurred direct transaction expenses of
     approximately $3 million.
     
(5)  Under purchase accounting, the total purchase price was allocated to the
     acquired assets and liabilities assumed based on their fair values. The
     difference between the cost of the transaction and the fair value of CAT
     net assets acquired was recorded as goodwill. Based on the purchase price
     paid, ACE recorded goodwill of approximately $217 millions from this
     transaction. This goodwill is being amortized over 25 years.     

(6)  To eliminate CAT's shareholder's equity.

PRO FORMA FOOTNOTES WITH RESPECT TO THE SHARE OFFERING

(7)  On April 14, 1998, the Company sold 16.5 million ordinary shares for net
     proceeds of approximately $605.9 million. A portion of the proceeds was
     used to repay the $385 million of short-term bank borrowings used to
     finance the CAT Acquisition (see note 3 above).
