                                                            Page 11 of 258 Pages
<PAGE>
 
future violations of, or prohibiting or mandating activities subject
to, federal or state securities laws or finding any violation with respect to
such laws.

Item 3.  Source and Amount of Funds or Other Consideration.
         ------------------------------------------------- 

     The Filing Parties used their working capital funds to purchase the shares
of Common Stock of the Company (the "Shares") to which this statement relates.

     The amount of funds used to date to acquire the Shares is approximately
$1,858,100 (exclusive of brokerage fees and commissions).

Item 4.  Purpose of Transaction.
         ---------------------- 

     The Filing Parties acquired their holdings of the Common Stock because they
believed that the Common Stock represented a favorable investment opportunity.
The Filing Parties believe that the current market valuation of the Common Stock
does not fully reflect the inherent value of the Company's business. The Filing
Parties have come to believe that the policies followed by the Board of
Directors (the "Board") in recent years have failed to maximize shareholder
value and that current management of the Company has failed to capitalize on, or
consider thoroughly, potential opportunities to enhance shareholder value
through, among other options, a business combination or sale of the Company or
its assets.

     Therefore, to seek to enhance shareholder value, the Filing Parties intend
to support Mr. Paul R. Dupee, Jr. (the "Soliciting Shareholder") in connection
with his commencement of a formal solicitation of consents in accordance with
applicable proxy regulations (the "Consent Solicitation"). The Consent
Solicitation seeks to enact certain proposals that would elect a majority of the
Company's Board who are committed, subject to their fiduciary duties, to
pursuing strategic alternatives to enhance shareholder value, including a
business combination or a sale of the Company or its assets.

     J O Hambro & Company, J O Hambro Asset Management, J O Hambro Investment 
Management and GFS are not participants in the Consent Solicitation but may be 
deemed to be members of a group with the other Filing Parties, the Soliciting 
Shareholder and the other participants in the Consent Solicitation (the "Group")
by virtue of their beneficial ownership of the Common Stock and their 
relationship to certain participants in the Consent Solicitation.

     The Filing Parties believe that the Company could increase shareholder
value by engaging in a business combination with, or sale to, another company in
the managed health care business because the memberships in the Company's HMOs
are likely to be given a higher market value in such a transaction than is
reflected in the current market price for the Company's Common Stock. In
addition, the Filing Parties believe that such a transaction would improve the
utilization of the Company's net operating loss carryforward, which is presently
providing little value to the Company because of the Company's low level of
profitability.

     On April 8, 1998, the Soliciting Shareholder filed a revised preliminary
consent solicitation statement (the "Preliminary Statement") with the Securities
and Exchange Commission pursuant to the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and the applicable rules thereunder. The
Preliminary Statement described the proposals of the Soliciting Shareholder,
which would, in part, add ten new directors to the Board, thereby increasing the
authorized number of directors to seventeen and fill the resulting new
directorships with the Soliciting Shareholder Nominees (as defined below), who
would constitute a majority of the Board. The Soliciting Shareholder has also
proposed repealing any bylaw amendments adopted by the Board since February 1,
1998.

                                                            Page 12 of 258 Pages
<PAGE>
 
     According the Preliminary Statement, the Soliciting Shareholder has
proposed for election ten people (the "Soliciting Shareholder Nominees") to fill
the newly-created directorships including Christopher H. B. Mills, Enrique F.
Gittes and Claudia M. Perkins (collectively, the "J O Hambro Nominees"). Mr.
Mills is a Filing Party. Mr. Gittes has served as Director of NASCIT, a Filing
Party, since 1993, and Ms. Perkins has served as a Director of J O Hambro
Capital Management, a Filing Party, since 1995.

     Mr. Mills, along with the Soliciting Shareholder and another Soliciting
Shareholder Nominee, will solicit individuals, brokers, banks, bank nominees and
other institutional holders in connection with the Consent Solicitation and will
not receive additional compensation for such solicitation.

     The J O Hambro Nominees have no present intention to change the existing
senior management of the Company and intend to support the appointment of a 
committee to oversee the implementation of the plan to pursue strategic 
alternatives.

     The Soliciting Shareholder, J O Hambro Capital Management, NASCIT and
American Opportunity Trust have entered into an oral agreement under which the
costs of the Consent Solicitation will be shared 40% by the Soliciting
Shareholder, 40% by NASCIT and 20% by American Opportunity Trust. The J O Hambro
Nominees expect to join the other Soliciting Shareholder Nominees in supporting
the Soliciting Shareholder's request for reimbursement of costs and expenses in
connection with the Consent Solicitation. None of the Filing Parties will
receive any fee in connection with the Consent Solicitation.

     Although certain of the Filing Parties have agreed to share the costs
associated with the Consent Solicitation, the Filing Parties have not agreed,
and are not contractually obligated, to vote the shares of Common Stock
beneficially owned by such Filing Parties in any manner in connection with the
Consent Solicitation or with respect to any other vote of the shareholders of
the Company. The Filing Parties reserve the right to participate in or initiate,
alone or with others, any other plans, proposals or transactions of a similar or
different nature with respect to the Company or its securities.

     The Filing Parties intend to review their investment in the Company on a
continuing basis and, depending on various factors, including the Company's
business, affairs and financial position, other developments concerning the
Company, the price level of the Common Stock, conditions in the securities
markets and general economic and industry conditions, as well as other
investment opportunities available to the Filing Parties, may in the future take
such actions with respect to their investment in the Company as they deem
appropriate in light of the circumstances existing from time to time. Such
actions may include the purchase of additional Common Stock in the open market,
in privately negotiated transactions or otherwise, or the sale at any time of
all or a portion of the Common Stock now owned or hereafter acquired by the
Filing Parties to one or more purchasers. The Filing Parties may revise the
proposals or submit additional proposals for action by shareholders by written
consent or for adoption by shareholders at any meeting of shareholders.

     Except as described in this Item 4, as of the date of this statement none
of the Filing Parties has formulated any plans or proposals that relate to or
would result in: (a) the acquisition by any person of additional securities of
the Company, or the disposition of securities of the

                                                            Page 13 of 258 Pages
<PAGE>
 
Company; (b) an extraordinary corporate transaction, such as a merger,
reorganization or liquidation of the Company or its subsidiaries, if any; (c) a
sale or transfer of a material amount of assets of the Company or its
subsidiaries, if any; (d) any change in the present board of directors or
management of the Company, including any change in the number or term of
directors or the filling of any existing vacancies on the board; (e) any
material change in the present capitalization or dividend policy of the Company;
(f) any other material change in the Company's business or corporate structure;
(g) changes in the Company's charter or bylaws or other actions that may impede
the acquisition of control of the Company by any person; (h) causing a class of
securities of the Company to be delisted from a national securities exchange or
to cease to be authorized to be quoted in an interdealer quotation system of a
registered national securities association; (i) causing a class of equity
securities of the Company to become eligible for termination of registration
pursuant to Section 12(g)(4) of the Exchange Act; or (j) any action similar to
those enumerated above.

Item 5.  Interest in Securities of the Issuer.
         ------------------------------------ 

     (a) - (b) The aggregate number and percentage of the outstanding Common
Stock of the Company beneficially owned (i) by each of the Filing Parties, and

     Secondment Services Agreement in its original form) of the Company and its
     subsidiaries on the last day of the preceding financial period of the
     Company and (b) the amount of the Fee payable to GIM pursuant to Clause
     5(1) of the Secondment Services Agreement in respect of that financial

(2)  In addition, the Company shall pay to the Manager a transaction fee of
     (Pounds) 200 per transaction effected for the Portfolio by the Manager, as
     evidenced by a contract note.

(3)  The Company shall bear the expenses of any kind incurred by or on behalf of
     the Manager in the carrying out of its duties and the provision of services
     and facilities hereunder, save for telex, telephone and other routine

     accommodation and secretarial and clerical staff for the normal performance

     January in each year (in this sub-clause referred to as "Payment Dates")
     but if the amount of the fee in respect of any financial period is not
     ascertained by 30th April in that financial period, the Company shall pay

     securities or any reorganisation, redemption, consolidation, sub-division

(6)  An amount equal to any amount payable to the Manager pursuant to this
     Clause shall be paid by the Company to the Manager promptly after delivery
     to the Company by the Manager of an invoice giving reasonable details in
     respect thereof.  Notwithstanding the foregoing, the Manager shall be
     entitled, without delivery of an invoice as 

                                                            Page 62 of 258 Pages

     aforesaid, to charge any such amount to the Portfolio subject to notifying
     the Company in writing of the amount thereof promptly thereafter.

9.   Subsidiaries
     ------------

     If the Company has at any time one or more subsidiaries then, unless
     otherwise directed by the Board, the Manager shall in addition provide the
     same services to such subsidiaries as it provides hereunder to the Company.

10.  Freedom to act
     --------------

     The services of the Manager to the Company under this Agreement shall not
     be exclusive and the Manager shall be free to render similar services to

     (b)  either party shall have a receiver or administrator appointed over the
          whole or any party of their assets or a resolution is passed or an
          order made for the winding-up of such party other than as mentioned in
          sub-clause (2) below;

     the other party shall be entitled to terminate the appointment under this
     Agreement forthwith by giving written notice of termination to such party.

(2)  On termination of the appointment of the Manager, the Manager shall be
     entitled to receive all fees and other money accrued due up to the date of
     such termination but shall not be entitled to compensation in respect of
     termination (except where such appointment is terminated by the Manager in
     accordance with sub-clause (1)(a) of this Clause or by the Company in
     breach of Clause 2) and the Manager shall deliver to the Company or as it
     shall direct, all books of account, records, registers, correspondence,
     documents and assets belonging to the Company or any subsidiary in
     possession of or under the control of the Manager and take all necessary
     steps to vest in the Company any assets previously held in the name of or

and conditions hereof, in relation to the Client's investments and cash which

Portfolio and to make investments and changes in investments on the Client's
behalf and as the Client's agent within the investment policy agreed between
JOHP and the Client and set out in Part I of Schedule II. Such policy shall be

Portfolio JOHP shall seek best execution at all times and may (subject to the
investment policy set out in Part I of Schedule II) deal on such markets or
exchanges and with such counterparties as it thinks fit. The Client agrees that

regulations of the relevant market or exchange and that JOHP may take all such
steps as may be required or permitted by such rules and regulations and/or by
good market practice.

lent by JOHP to a third party except as otherwise agreed between the Client and
JOHP in writing.

6.  JOHP may supplement the funds in the Portfolio by borrowing on the Client's
behalf but only for the purpose of funding short-term deficiencies arising in
the normal course of JOHP's duties hereunder to an extent which is not material
in the context of the Portfolio taken as a whole. JOHP will not borrow money on
the Client's behalf against the security of any of the Client's investments,
documents of title or property.

7.  JOHP may commit the Client to underwrite any issue or offer for sale of
securities without the Client's prior written consent.

8.  JOHP may act as principal in any transaction for the Client provided that
JOHP shall secure for the Client best execution of such transaction.

9.  Subject to the IMRO Rules, JOHP may, without prior reference to the Client,
enter into a transaction on behalf of more than one client collectively.

10.  JOHP has the right under this Agreement to effect transactions on the
Client's behalf in investments the price of which may be being stabilised. The
attention of the Client is referred to the statement contained in Schedule II
relating to stabilisation. Signature of this Agreement by or on behalf of the
Client shall act as acknowledgment by the Client of receipt of such statement
prior to entry into this Agreement.

CONFLICTS OF INTEREST

11.  Subject to paragraphs 12 and 13, JOHP shall not undertake any transactions
on the Client's behalf in which JOHP has directly or indirectly a material
interest or have any relationship with another party which may involve a
conflict with JOHP's duty to the Client unless that interest or relationship is
disclosed in writing to the Client.

12.  The Client's Portfolio may contain securities of which the issue or offer
for sale is underwritten, managed or arranged by an Associate (as defined in the
Rules of IMRO) of JOHP during the preceding twelve months.

                                                            Page 82 of 258 Pages

13.  The Client understands that JOHP's directors or staff may from time to time
hold shares or securities including holdings that may be in the Portfolio, and
that JOHP's directors or staff may from time to time be directors of companies
whose shares are held in the Portfolio.

14.  The Client acknowledges that JOHP may acquire or dispose of on the Client's
behalf shares or units in any fund, company, trust or Collective Investment
Scheme (as defined by the Rules of IMRO) under JOHP's management (or in a fund,
company, trust or Collective Investment Scheme connected with JOHP) if JOHP
considers such an investment to be appropriate for inclusion in or exclusion
from the Portfolio.

CUSTODIAL SERVICES

15.  (a)  Save where the Client has notified JOHP in accordance with paragraph
          15(b), in those cases where the Client is situated in the United
          Kingdom registerable investments will be registered in the name of an
          Eligible Custodian (as defined in the Rules of IMRO) situated in the
          United Kingdom and nominated by JOHP.

     (b)  In those cases where the Client is situated overseas or where the
          Client so requests by notice in writing to JOHP, registerable
          investments will be registered in the name of an Eligible Custodian
          situated outside the United Kingdom and nominated by JOHP.

     (c)  All documents of title (including those in bearer form) will be
          retained in the custody of an Eligible Custodian nominated by JOHP and
          situated in the United Kingdom or overseas as applicable.

     (d)  None of the Eligible Custodians as aforesaid shall be Associates of
          JOHP. However, the Client's registerable investments may at any time
          be registered in the name of a nominee company which is an Associate
          of JOHP and Client's documents of title may be held by that Associate
          at any time after JOHP shall have given the Client written notice of
          its intention to do so. Such notice shall specify the nature of its
          association with such Associate.

ACCOUNTS, INTEREST AND DIVIDENDS

16.  The following Client accounts, together with such others that may be
required, will be maintained by JOHP.

(1)  INVESTMENT ACCOUNT

          The Client's investments will be held in this account.  Subject to
          paragraphs 5 and 6, JOHP shall not lend the Client's investments to
          any third party and shall not borrow money on the Client's behalf
          against the security of the Client's investments.

(2)  CAPITAL ACCOUNT

<PAGE>
 
          All uninvested cash will be held in this account by a bank chosen by
          JOHP. The account will be debited with the cost of purchases on the
          Client's behalf and with sums due and payable by the Client to JOHP
          and will be credited with the net proceeds of sales on the Client's
          behalf. Money drawn on behalf of the Client from the account shall not
          exceed the total of money held in the account on behalf of the Client
          at that time. Interest will be paid on sums standing to the credit of
          the account and held on the Client's behalf at the prevailing market
          rate. The interest will be paid quarterly and will be credited to the
          Income Account on the Client's behalf.

(3)  SETTLEMENT ACCOUNT

          Money debited to the Capital Account in respect of the cost of
          purchases made on the Client's behalf and money received and
          receivable upon settlement of each sale made on the Client's behalf
          will be credited to this account and held there until the relevant
          settlement date.

(4)  INCOME ACCOUNT

          Dividends and interest received on investments within the Portfolio
          will be credited to this account. Balances on the account will be paid
          away quarterly in accordance with the Client's instructions or, in the
          absence of such instructions, will be transferred quarterly to the
          Capital Account as soon as reasonably practicable after the last day
          of each such quarter being 5th April, 30th June, 5th October and 31st
          December in each year. Money drawn on behalf of the Client from the
          account shall not exceed the total of money held in the account on
          behalf of the Client at that time. Interest will not be paid on monies
          held in this account.

     (e)  OFF-SHORE FUNDS

          In those cases where the Client is situated overseas or if the Client
          notifies JOHP in writing that the Client wishes cash in the Portfolio
          to be held outside the United Kingdom, JOHP will be (subject to
          applicable laws and regulations) hold such cash in a bank account
          outside the United Kingdom.

17.  The Client may at any time instruct JOHP to realize any or all of the
investments in the Portfolio and may withdraw any sum standing to the credit of
the Capital Account and held on the Client's behalf.

reasonably practicable after that date.

<PAGE>
 
19.  In the interests of proper administration of the Portfolio and for related
investment purposes JOHP, its representatives or employees, may call upon the
Client by telephone, visit or otherwise communicate orally with the Client
without express invitation. The Client's attention is drawn to the fact that the
Client will forfeit any right conferred by section 56 of the Financial Services
Act 1986 to treat as unenforceable any investment agreement entered into in the
course of or in consequence of such a call.

ADMINISTRATION

20.  Contract notes in respect of every purchase and sale on the Client's behalf
will be sent to the Client before the close of business on the day next
following the day on which the transaction was effected.

21.  JOHP will on the Client's request forward details of all transactions on
the Client's behalf to the Client's tax advisor without additional charge.

22.  The Client may (upon giving reasonable notice) inspect all copy contract
notes, vouchers and copies of entries in books or electronic recording media
kept by JOHP or to which JOHP has access relating to the transactions effected
by JOHP on the Client's behalf and those records will be maintained by JOHP or
JOHP will ensure that they are maintained for not less than seven years from the
date of the relevant transaction.

23.  All documents will be sent to the Client at the address given above unless
and until otherwise directed in writing. The Client agrees that it will
immediately notify JOHP in writing of any change of address, and that JOHP will
not be responsible for any consequences which may arise from failure to do so.

REVIEWS AND VALUATIONS

24.  JOHP will prepare reviews of the Portfolio incorporating an up-to-date
valuation of each investment comprised in the Portfolio and a statement of the
basis on which it was valued on a six monthly basis or at such other frequency
as may be agreed between JOHP and the Client. Such reviews shall be prepared as
at such half yearly or other dates as shall be agreed between JOHP and the
client from time to time (each such date being referred to as a "Valuation
Date"), and JOHP will send such reviews to the Client within twenty-five
business days of each Valuation Date.

25.  On each Valuation Date cash will be valued at its face value and each
investment will be valued at its middle market price on the relevant stock
exchange at the close of business on such day or (if not a business day) on the
nearest prior business day as is supplied by "Exshare" or any other suitable
information service chosen by JOHP (which figures shall be binding save for
manifest error). For the purpose of valuing in sterling any foreign currency or
any security listed on a foreign stock exchange the price of which is quoted in
currency other than sterling, the valuation and middle market exchange rates
supplied by "Exshare" or any other suitable information service chosen by JOHP
shall be applied. In the absence of that valuation or exchange rate, the middle
market price as determined by the Daily Official List of The Stock Exchange or
the equivalent list for any relevant stock exchange will be applied. If none of
the foregoing methods of valuation are available, the investments in question
will be

                                                            Page 85 of 258 Pages
<PAGE>
 
valued in such other manner (by JOHP or such other person selected by
JOHP) as shall in JOHP's opinion be fair.

26.  JOHP accepts no liability for any period longer than 25 business days
between any Valuation Date and the despatch of a review to the Client of his
Portfolio which has elapsed as result of any act or omission of any third party.

VOTING AND OTHER RIGHTS

27.  JOHP will be entitled at its discretion and without notice to the Client to
procure or to refrain from procuring the exercise of voting and other rights and
privileges attaching to the investments comprised in the Portfolio and to accede
or refrain from acceding to any compromise or arrangement in relation to any
scheme of arrangement or scheme for reconstruction or amalgamation involving any
such investment. JOHP will not forward to the Client any circulars, notices or
proxy cards received in respect of investments comprised in the Portfolio.

FEES, COMMISSIONS AND EXPENSES

28.   (a) The Client will pay a management fee to JOHP in respect of the period
          beginning with first receipt by JOHP of any investments or money from
          the Client and ending with a Valuation Date (as defined in paragraph
          24) and each period thereafter starting with the day after any
          Valuation Date and ending on the next Valuation Date (or the
          Termination Date as defined in paragraph 39 if sooner).

     (b)  The management fee shall be calculated in accordance with the 'Scale
          Rates and Charges' set out in Schedule III.

     (c)  The management fee shall be payable not later than 14 days after
          despatch to the Client of an invoice which shall be sent to the Client
          as soon as is reasonably practicable after each Valuation Date. Unless
          otherwise instructed the Client's Capital Account will be debited with
          the amounts due to JOHP on the l4th day after despatch of such
          invoice.

     (d)  In addition the Client shall reimburse JOHP for any expenses or
          liabilities which it may incur in properly carrying out its duties
          hereunder.

29.  The management fee shall be deemed to have accrued on a day-to-day basis,
so that, if this Agreement commences or terminates other than on a Valuation
Date (as defined in paragraph 24), the amount of the fee shall be duly
apportioned.

30.  Commissions (as set out in Schedule III) will be payable by the Client on
purchases and sales of investments together with all expenses including stamp
duties, stamp duty reserve tax and VAT thereon (if applicable). The Client
recognizes that JOHP may gain a commission benefit from dealing in a bulk
purchase or sale on behalf of JOHP's clients, one of whom may be the Client, or
from return commissions which benefit JOHP shall be entitled to retain. JOHP
will be free to accept and retain as an addition to its fees and commissions any
other

commissions which it receives in the course of its dealing on the Client's
behalf: all such benefits and receipts shall supplement any other remuneration
receivable by JOHP in connection with transactions effected by JOHP with or for
the Client under this or any other agreement with the Client and the Client
consents to all such benefits and receipts as are referred to above without
prior disclosure of the same to the Client on a case-by-case basis provided that
JOHP undertakes to secure for the Client best execution of all transactions
affected with or through a party from whom JOHP receives such benefits and
commissions, disregarding any benefit which the Client might obtain directly or
indirectly as a result of such arrangements.

31.  JOHP shall be entitled to alter the manner of computing or charging its
fees, commissions and expenses or of paying interest on the money held on the
Client's behalf in the Capital Account (including with prejudice to the
generality of the foregoing its scale rates and charges) by giving one month's
prior notice in writing to the Client.

RESPONSIBILITY AND INSURANCE

32.  JOHP will indemnify the Client in respect of any loss incurred as a result
of negligence, wilful default or fraud by JOHP or any of its employees. Subject
to the above, JOHP will not be responsible or liable for any claim, loss,
damage, expense or costs arising by reason of any of the following:

(1)  any investment decision taken and acted upon in accordance with the terms
     of this Agreement; or

(2)  any delay or default in the performance of its obligations under this
     Agreement arising in consequence of any event or circumstance beyond the
     reasonable control of JOHP; or

(3)  any act or omission on the part of any of the banks or nominee companies
     controlled by them or other eligible custodians as referred to in paragraph
     15 or any other person to which any of them shall have delegated its
     function or on the part of any other third party whatsoever; or

(4)  any consequential loss suffered in consequence of any act or omission of
     JOHP or any breach of JOHP of any term of this Agreement.

33.  The Client agrees to indemnify and keep indemnified JOHP from and against
all demands, claims, liabilities, losses, damages, costs and expenses whatsoever
incurred by JOHP arising out of the breach by the Client of any warranty or by
reason of any failure by the Client to comply with and/or perform any of the
terms and conditions contained in this Agreement.

34.  Where the Client is a joint account (whether or not a trust account) JOHP
shall unless and until otherwise directed in writing by all the persons named in
the joint account, be entitled to act on the instructions of any of them and
shall not in any whatsoever be liable to the others for doing so.

<PAGE>
 
35.  JOHP has effected insurance to provide for the protection of the Client
against losses arising from any negligence of JOHP or any dishonesty of
employees of JOHP.

36.  Under Section 54 of the Financial Services Act 1986 The Securities and
Investments Board has established a scheme for compensating investors by which
the Client may be entitled to compensation in the event of JOHP's inability to
meet any liabilities to the Client.  JOHP will make available to the Client upon
request a statement describing the Client's rights to compensation under the
scheme.

DELEGATION AND USE OF AGENTS

37.  JOHP may delegate any of its functions under this Agreement to an Associate
and may provide information about the Client and the Portfolio to any such
Associate but JOHP's liability to the Client for all matters so delegated shall
not be affected thereby.  JOHP shall give to the Client written notice of any
delegation of a function which involves the exercise of its discretionary
investment management powers.

38.  JOHP may employ agents (including Associates) to perform any
administrative, dealing, custodial and ancillary services required to enable
JOHP to perform its services under this Agreement.  JOHP undertakes to act in
good faith and with due diligence in the choice and use of such agents.

TERMINATION OF AGREEMENT

39.  This Agreement may be terminated by either party by giving written notice
of termination to the other at any time.  Termination shall take effect on the
day upon which the other party actually receives the notice (the "Termination
Date") provided that, where the client is a joint account, notice of termination
by JOHP shall be given to every person named in the joint account and in such
circumstances the Termination Date shall be deemed to be the day after the date
of posting by first class recorded delivery or other appropriate means to all
persons named in the joint account.

40.  Upon the Termination Date, JOHP will complete expeditiously all
transactions in progress at termination but will not execute any further
transactions for the Client.  Upon all fees, commissions, expenses and other
sums due to it and any other liabilities for which it may be or become liable in
connection with the management of the Portfolio being settled or adequately
secured to the satisfaction of JOHP, JOHP will ensure that all investments and
cash balances held on the Client's behalf will, after any outstanding security
registration, stock exchange settlements and other administrative matters have
been completed and as soon as reasonably practicable, be transferred to the
Client or dealt with in accordance with the Client's instructions, in all cases
at the cost of the Client.

41.  Termination will not affect accrued rights, existing commitments or any
contractual provision intended to survive termination and will be without
penalty or other additional payment except that JOHP may charge the Client an
amount equal to:

                                                            Page 88 of 258 Pages
<PAGE>
 
(1)  the relevant proportion of the management fee, corresponding to that part
     of the period ending on a Valuation Date by reference to which fees are
     payable, which has expired when this Agreement is terminated;

(2)  any additional expenses which JOHP necessarily incurs in terminating this
     Agreement; and

(3)  any losses necessarily realized in settling or concluding outstanding
     obligations.

42.  The death, bankruptcy or other incapacity or, in the case of a body
corporate, the cessation of business of the Client or a petition being presented
or a meeting being convened to consider a resolution for the liquidation of the
Client shall not of itself terminate JOHP's appointment; but JOHP may at its
discretion treat its receipt of actual notice of any such events as if it were a
written notice of termination from the Client.

43.  If the Client is a joint account the Client's obligations under this
Agreement shall be joint and several. On the death of any of the persons
constituting the Client (being survived by any such other person), the Agreement
shall not terminate and, except in the case of trustees, the interest of the
deceased in the Portfolio shall automatically enure to the benefit of the
survivor(s) unless otherwise specified by notice in writing to JOHP.

CLIENT WARRANTIES

44.  The Client warrants that the Client is the beneficial owner (or the duly
authorized agent of the beneficial owner) of the whole of the Portfolio free
from all liens, charges, encumbrances and restrictions on transfer except
insofar as advised by the Client to JOHP, and will so remain during the currency
of this Agreement.

45.  The Client warrants that the Client is empowered to enter into this
Agreement without the consent or authority of any other party and in the case of
a Client being a body corporate the Client warrants that by entering into this
Agreement it is not nor will it be in breach of its Memorandum or Articles of
Association or any other relevant document.

GENERAL

46.  Terms and expressions defined in the rules of IMRO for the time being in
force shall where the context so admits bear the same meaning in this Agreement.

47.  The Clause headings in this Agreement are included for ease of reference

Agreement or as may be required by law, or where requested by regulatory

                                 THE PORTFOLIO

                    Valuation and composition of Portfolio
          (see attached letter/opening valuation - where applicable)


                                  SCHEDULE II

                INVESTMENT POLICY, GUIDELINES AND RESTRICTIONS

                  PART I - Investment Policy including basis
                         of measurement of performance

The investment objectives are to maintain a maximum total return commensurate
with safety and the protection of the underlying value of the capital of the
fund.



The performance will be measured against the F.T. All Share Index, any other
appropriate Index or measure of performance agreed upon by JOHP and the Client.



                     PART II - Guidelines and Restrictions

1.   There will be no restrictions placed on the types of investment in which
     the money comprised in the Portfolio will be invested provided that the
     services to be provided by JOHP will not include advising on or effecting
     Contingent Liability Transactions, nor will they, without the express
     authority of the Client, relate to options, futures or contracts for
     differences (or to any right or interest in such investments).


2.   The contents of the Portfolio may be invested in any market save for the
     following:


     There shall be no restriction on the amount of monies or proportion of the
     Portfolio invested in any one investment or type of investment permitted
     hereunder provided that, subject to the provisions relating to overdraft
     contained in paragraph 6 of this Agreement, under no circumstances will
     JOHP make investments on behalf of the Client to a value in excess of the
     aggregate of the value of the funds and securities held by JOHP on behalf
     of the Client in the accounts referred to in paragraph 16 of this
     Agreement.

<PAGE>
 
            PART III - Risk Warnings and Risk Disclosure Statement


                 Investments Denominated in Foreign Currencies

If a liability of the Client in one currency is to be matched by an asset in a
different currency, or if JOHP provides services under this Agreement relating
to an investment denominated in a foreign currency, a movement in exchange rates
may have an effect which may be either favorable or unfavorable on the
investment, which effect may be separate from the gain or loss otherwise
experienced on such investment.

                      Investments not readily realisable

Certain categories of investments comprised in the Portfolio may not be readily
realisable.  You should be aware that there can be no certainty that market
makers or brokers will be prepared to deal in such investments and that proper
information for determining their current value may not be available.

                                   Warrants

A warrant is a right to subscribe for shares, debentures, loan stock or
government securities, and is exercisable against the original issuer of the
securities.  Warrants often involve a high degree of gearing so that a
relatively small movement in the price of the underlying security results in a
disproportionately large movement, unfavorable as well as favorable, in the
price of the warrant.  The prices of warrants can therefore be volatile.

                                 Stabilisation

This statement is made in compliance with Rule 14 of Chapter IV of the rules of
IMRO.

"We or our representatives may from time to time effect on your behalf or
recommend to you transactions in securities which are the subject of a recent
new issue where the price of those transactions may have been influenced by bids
made or transactions effected for the purpose of stabilising the price of those
securities.  You should read the explanation below carefully.  Its purpose is to
enable you to judge whether you wish your funds to be invested at all in such
securities, or, if so, whether you wish to authorize us generally to effect
transactions in such securities on your behalf without further reference to you
or whether you wish to be consulted before any particular transaction is
effected on your behalf.

Stabilisation is a process whereby the market price of a security is pegged or
fixed during the period in which a new issue of securities is sold to the
public.  Stabilisation may take place in the new issue or in other securities
related to the new issue in such a way that the price of the other securities
may affect the price of the new issue or vice versa.

The reason stabilisation is permitted is that when a new issue is brought to
market the sudden glut will sometimes force the price lower for a period of time
before buyers are found for the securities on offer.

                                                            Page 92 of 258 Pages
<PAGE>
 
As long as he obeys a strict set of rules the "stabilising manager", normally
the issuing house chiefly responsible for bringing a new issue to market, is
entitled to buy securities in the market that he has previously sold to
investors or allotted to institutions who were included in the new issue but who
have decided not to continue participating.  The effect of this may be to keep
the price at a higher level than would otherwise be the case during the period
of stabilising.

The rules limit the period in which he may stabilise, fix the price at which he
may stabilize (in the case of shares and warrants but not bonds), and require
him to disclose that he may be (but not that he is) stabilising.

The fact that a new issue or a related security is being stabilized does not in
itself mean that investors are not interested in the issue, but neither should
the existence of transactions in an issue where stabilising may take place be
relied upon as an indication that investors are interested in the new issue or
interested in purchasing at the price at which transactions are taking place".

     (hereafter known as the "Client")

     of 3 Chester Street, London SWIX 7BB
        ----------------------------------------------------

                                                                     (address)
     -------------------------------------------------------             

NOW IT IS HEREBY AGREED as follows:

APPOINTMENT AND STATUS OF CLIENT

1.   The Client, a Private Customer as defined in the Rules of IMRO, hereby
     appoints JOHP to act as discretionary investment manager, subject to the
     terms and conditions hereof, in relation to the Client's investments and
     cash which are from time to time placed under the management of JOHP (the
     "Portfolio") and JOHP hereby agrees to manage and administer the Portfolio.
     The appointment will commence on the date on which this Agreement is
     delivered to JOHP by the Client having been signed first by the Client then
     by JOHP.  The assets comprising the Portfolio and their opening value are
     set out in Schedule 1.

MANAGEMENT OF INVESTMENTS

2.   JOHP shall have complete discretion, power and authority to manage the
     Portfolio and to make investments and changes in investments on the
     Client's behalf and as the Client's agent within the investment policy
     agreed between JOHP and the Client and set out in Part 1 of Schedule II.
     Such policy shall be subject to the guidelines and restrictions set out in
     Part II of Schedule II and to any guidelines, restrictions and instructions
     specified in writing from time to time by the Client or by the Client's
     duly authorized agent (written notice of whose authority shall have been
     received by JOHP).  The Client's attention is specifically drawn to the
     warnings set out in Part III of Schedule II.

<PAGE>
 
3.   JOHP shall not be obliged to undertake the management of investments the
     management of which would in its opinion be onerous to it.

DEALING TERMS

4.   Subject as set out in paragraph 9, in effecting transactions for the
     Portfolio JOHP shall seek best execution at all times and may (subject to
     the investment policy set out in Part I of Schedule II) deal on such
     markets or exchanges and with such counterparties as it thinks fit.  The
     Client agrees that all such transactions will be effected in accordance
     with the rules and regulations of the relevant market or exchange and that
     JOHP may take all such steps as may be required or permitted by such rules
     and regulations and/or by good market practice.

5.   The Client's investments or documents of title or certificates evidencing
     title to investments or any other property belonging to the Client will not
     be lent by JOHP to a third party except as otherwise agreed between the
     Client and JOHP in writing.

6.   JOHP may supplement the funds in the Portfolio by borrowing on the Client's
     behalf but only for the purpose of funding short-term deficiencies arising
     in the normal course of JOHP's duties hereunder to an extent which is not
     material in the context of the Portfolio taken as a whole.  JOHP will not
     borrow money on the Client's behalf against the security of any of the
     Client's investments, documents of title or property.

7.   JOHP may commit the Client to underwrite any issue or offer for sale of
     securities without the Client's prior written consent.

8.   JOHP may act as principal in any transaction for the Client provided that
     JOHP shall secure for the Client best execution of such transaction.

9.   Subject to the IMRO Rules, JOHP may, without prior reference to the Client,
     enter into a transaction on behalf of more than one client collectively.

10.  JOHP has the right under this Agreement to effect transactions on the
     Client's behalf in investments the price of which may be being stabilized.
     The attention of the Client is referred to the statement contained in
     Schedule II relating to stabilization.  Signature of this Agreement by or
     on behalf of the Client shall act as acknowledgment by the Client of
     receipt of such statement prior to entry into this Agreement.

CONFLICTS OF INTEREST

11.  Subject to paragraphs 12 and 13, JOHP shall not undertake any transactions
     on the Client's behalf in which JOHP has directly or indirectly a material
     interest or have any relationship with another party which may involve a
     conflict with JOHP's duty to the Client unless that interest or
     relationship is disclosed in writing to the Client.

     for sale is underwritten, managed or arranged by an Associate (as defined
     in the Rules of IMRO) of JOHP during the preceding twelve months.

<PAGE>
 
13.  The Client understands that JOHP's directors or staff may from time to time
     hold shares or securities including holdings that may be in the Portfolio,
     and that JOHP's directors or staff may from time to time be directors of
     companies whose shares are held in the Portfolio.

14.  The Client acknowledges that JOHP may acquire or dispose of on the Client's
     behalf shares or units in any fund, company, trust or Collective Investment
     Scheme (as defined by the Rules of IMRO) under JOHP's management (or in a
     fund, company, trust or Collective Investment Scheme connected with JOHP)
     if JOHP considers such an investment to be appropriate for inclusion in or
     exclusion from the Portfolio.

CUSTODIAL SERVICES

15.  (a)  Save where the Client has notified JOHP in accordance with paragraph
          15(b), in those  cases where the Client is situated in the United
          Kingdom registerable investments will be registered in the name of an
          Eligible Custodian (as defined in the Rules of IMRO) situated in the
          United Kingdom and nominated by JOHP.

     (b)  In those cases where the Client is situated overseas or where the
          Client so requests by notice in writing to JOHP, registerable
          investments will be registered in the name of an Eligible Custodian
          situated outside the United Kingdom and nominated by JOHP.

     (c)  All documents of title (including those in bearer form) will be
          retained in the custody of an Eligible Custodian nominated by JOHP and
          situated in the United Kingdom or overseas as applicable.

     (d)  None of the Eligible Custodians as aforesaid shall be Associates of
          JOHP.  However, the Client's registerable investments may at any time
          be registered in the name of a nominee company which is an Associate
          of JOHP and Client's documents of title may be held by that Associate
          at any time after JOHP shall have given the Client written notice of
          its intention to do so.  Such notice shall specify the nature of its
          association with such Associate.

ACCOUNTS, INTEREST AND DIVIDENDS

16.  The following Client accounts, together with such others that may be
     required, will be maintained by JOHP.

     (a)  INVESTMENT ACCOUNT

          The Client's investments will be held in this account.  Subject to
          paragraphs 5 and 6, JOHP shall not lend the Client's investments to
          any third party and shall not borrow money on the Client's behalf
          against the security of the Client's investments.

     (b)  CAPITAL ACCOUNT


                                                            Page 99 of 258 Pages
<PAGE>
 
          All uninvested cash will be held in this account by a bank chosen by
          JOHP.  The account will be debited with the cost of purchases on the
          Client's behalf and with sums due and payable by the Client to JOHP
          and will be credited with the net proceeds of sales on the Client's
          behalf.  Money drawn on behalf of the Client from the account shall
          not exceed the total of money held in the account on behalf of the
          Client at that time.  Interest will be paid on sums standing to the
          credit of the account and held on the Client's behalf at the
          prevailing market rate.  The interest will be paid quarterly and will
          be credited to the Income Account on the Client's behalf.

     (c)  SETTLEMENT ACCOUNT

          Money debited to the Capital Account in respect of the cost of
          purchases made on the Client's behalf and money received and
          receivable upon settlement of each sale made on the Client's behalf
          will be credited to this account and held there until the relevant
          settlement date.

     (d)  INCOME ACCOUNT

          Dividends and interest received on investments within the Portfolio
          will be credited to this account.  Balances on the account will be
          paid away quarterly in accordance with the Client's instructions or,
          in the absence of such instructions, will be transferred quarterly to
          the Capital Account as soon as reasonably practicable after the last
          day of each such quarter being 5th April, 30th June, 5th October and
          31st December in each year.  Money drawn on behalf of the Client from
          the account shall not exceed the total of money held in the account on
          behalf of the Client at that time.  Interest will not be paid on
          monies held in this account.

     (d)  OFF-SHORE FUNDS

          In those cases where the Client is situated overseas or if the Client
          notifies JOHP in writing that the Client wishes cash in the Portfolio
          to be held outside the United Kingdom, JOHP will be (subject to
          applicable laws and regulations) hold such cash in a bank account
          outside the United Kingdom.

17.  The Client may at any time instruct JOHP to realise any or all of the
     investments in the Portfolio and may withdraw any sum standing to the
     credit of the Capital Account and held on the Client's behalf.

18.  JOHP shall maintain separate ledger accounts on the Client's behalf.  All
     debits from and credits to the Investment Account and/or Capital Account
     and/or Income Account on the Client's behalf shall be recorded in the
     ledger accounts, and statements of account showing all transactions,
     payments and receipts up to and including 5th April of each year will be
     sent to the Client as soon as reasonably practicable after that date.

<PAGE>
 
19.  In the interests of proper administration of the Portfolio and for related
     investment purposes JOHP, its representatives or employees, may call upon
     the Client by telephone, visit or otherwise communicate orally with the
     Client without express invitation.  The Client's attention is drawn to the
     fact that the Client will forfeit any right conferred by section 56 of the
     Financial Services Act 1986 to treat as unenforceable any investment
     agreement entered into in the course of or in consequence of such a call.

ADMINISTRATION

20.  Contract notes in respect of every purchase and sale on the Client's behalf
     will be sent to the Client before the close of business on the day next
     following the day on which the transaction was effected.

21.  JOHP will on the Client's request forward details of all transactions on
     the Client's behalf to the Client's tax advisor without additional charge.

22.  The Client may (upon giving reasonable notice) inspect all copy contract
     notes, vouchers and copies of entries in books or electronic recording
     media kept by JOHP or to which JOHP has access relating to the transactions
     effected by JOHP on the Client's behalf and those records will be
     maintained by JOHP or JOHP will ensure that they are maintained for not
     less than seven years from the date of the relevant transaction.

23.  All documents will be sent to the Client at the address given above unless
     and until otherwise directed in writing.  The Client agrees that it will
     immediately notify JOHP in writing of any changes of address, and that JOHP
     will not be responsible for any consequences which may arise from failure
     to do so.

REVIEWS AND VALUATIONS

24.  JOHP will prepare reviews of the Portfolio incorporating an up-to-date
     valuation of each investment comprised in the Portfolio and a statement of
     the basis on which it was valued on a six monthly basis or at such other
     frequency as may be agreed between JOHP and the Client.  Such reviews shall
     be prepared as at such half yearly or other dates as shall be agreed
     between JOHP and the Client from time to time (each such date being
     referred to as a "Valuation Date"), and JOHP will send such reviews to the
     Client within twenty-five business days of each Valuation Date.

25.  On each Valuation Date cash will be valued at its face value and each
     investment will be valued at its middle market price on the relevant stock
     exchange at the close of business on such day or (if not a business day) on
     the nearest prior business day as is supplied by "Exshare" or any other
     suitable information service chosen by JOHP (which figures shall be binding
     save for manifest error).  For the purpose of valuing in sterling any
     foreign currency or any security listed on a foreign stock exchange the
     price of which is quoted in currency other than sterling, the valuation and
     middle market exchange rates supplied by "Exshare" or any other suitable
     information service chosen by JOHP shall be applied.  In the absence of
     that valuation or exchange rate, the middle market price as determined by
     the Daily Official List of The Stock 


                                                           Page 101 of 258 Pages
<PAGE>
 
     Exchange or the equivalent list for any relevant stock exchange will be
     applied. If none of the foregoing methods of valuation are available, the
     investments in question will be valued in such other manner (by JOHP or
     such other person selected by JOHP) as shall in JOHP's opinion be fair.

26.  JOHP accepts no liability for any period longer than 25 business days
     between any Valuation Date and the despatch of a review to the Client of
     his Portfolio which has elapsed as a result of any act or omission of any
     third party.

VOTING AND OTHER RIGHTS

27.  JOHP will be entitled at its discretion and without notice to the Client to
     procure or to refrain from procuring the exercise of voting and other
     rights and privileges attaching to the investments comprised in the
     Portfolio and to accede or refrain from acceding to any compromise or
     arrangement in relation to any scheme of arrangement or scheme for
     reconstruction or amalgamation involving any such investment.  JOHP will
     not forward to the Client any circulars, notices or proxy cards received in
     respect of investments comprised in the Portfolio.

FEES, COMMISSIONS AND EXPENSES

28.  (a)  The Client will pay a management fee to JOHP in respect of the period
          beginning with first receipt by JOHP of any investments or money from
          the Client and ending with a Valuation Date (as defined in paragraph
          24) and each period thereafter starting with the day after any
          Valuation Date and ending on the next Valuation Date (or the
          Termination Date as defined in paragraph 39 if sooner).

     (b)  The management fee shall be calculated in accordance with the 'Scale
          Rates and Charges' set out in Schedule III.

     (c)  The management fee shall be payable not later than 14 days after
          despatch to the Client of an invoice which shall be sent to the Client
          as soon as is reasonably practicable after each Valuation Date.
          Unless otherwise instructed the Client's Capital Account will be
          debited with the amounts due to JOHP on the 14th day after despatch of
          such invoice.

     (d)  In addition the Client shall reimburse JOHP for any expenses or
          liabilities which it may incur in properly carrying out its duties
          hereunder.

29.  The management fee shall be deemed to have accrued on a day-to-day basis,
     so that, if this Agreement commences or terminates other than on a
     Valuation Date (as defined in paragraph 24), the amount of the fee shall be
     duly apportioned.

30.  Commissions (as set out in Schedule III) will be payable by the Client on
     purchases and sales of investments together with all expenses including
     stamp duties, stamp duty reserve tax and VAT thereon (if applicable).  The
     Client recognises that JOHP may gain a commission benefit from dealing in a
     bulk purchase or sale on behalf of JOHP's 


                                                           Page 102 of 258 Pages
<PAGE>
 
     clients, one of whom may be the Client, or from return commissions which
     benefit JOHP shall be entitled to retain. JOHP will be free to accept and
     retain as an addition to its fees and commissions any other commissions
     which it receives in the course of its dealing on the Client's behalf: all
     such benefits and receipts shall supplement any other remuneration
     receivable by JOHP in connection with transactions effected by JOHP with or
     for the Client under this or any other agreement with the Client and the
     Client consents to all such benefits and receipts as are referred to above
     without prior disclosure of the same to the Client on a case-by-case basis
     provided that JOHP undertakes to secure for the Client best execution of
     all transactions effected with or through a party from whom JOHP receives
     such benefits and commissions, disregarding any benefit which the Client
     might obtain directly or indirectly as a result of such arrangements.

31.  JOHP shall be entitled to alter the manner of computing or charging its
     fees, commissions and expenses or of paying interest on the money held on
     the Client's behalf in the Capital Account (including with prejudice to the
     generality of the foregoing its scale rates and charges) by giving one
     month's prior notice in writing to the Client.

RESPONSIBILITY AND INSURANCE

32.  JOHP will indemnify the Client in respect of any loss incurred as a result
     of negligence, wilful default or fraud by JOHP or any of its employees.
     Subject to the above, JOHP will not be responsible or liable for any claim,
     loss, damage, expense or costs arising by reason of any of the following:

     (a)  any investment decision taken and acted upon in accordance with the
          terms of this Agreement; or

     (b)  any delay or default in the performance of its obligations under this
          Agreement arising in consequence of any event or circumstance beyond
          the reasonable control of JOHP; or

     (c)  any act or omission on the part of any of the banks or nominee
          companies controlled by them or other eligible custodians as referred
          to in paragraph 15 or any other person to which any of them shall have
          delegated its function or on the part of any other third party
          whatsoever; or

     (d)  any consequential loss suffered in consequence of any act or omission
          of JOHP or any breach of JOHP of any term of this Agreement.

33.  The Client agrees to indemnify and keep indemnified JOHP from and against
     all demands, claims, liabilities, losses, damages, costs and expenses
     whatsoever incurred by JOHP arising out of the breach by the Client of any
     warranty or by reason of any failure by the Client to comply with and/or
     perform any of the terms and conditions contained in this Agreement.

<PAGE>
 
34.  Where the Client is a joint account (whether or not a trust account) JOHP
     shall unless and until otherwise directed in writing by all the persons
     named in the joint account, be entitled to act on the instructions of any
     of them and shall not in any whatsoever be liable to the others for doing
     so.

35.  JOHP has effected insurance to provide for the protection of the Client
     against losses arising from any negligence of JOHP or any dishonesty of
     employees of JOHP.

36.  Under Section 54 of the Financial Services Act 1986 The Securities and
     Investments Board has established a scheme for compensating investors by
     which the Client may be entitled to compensation in the event of JOHP's
     inability to meet any liabilities to the Client.  JOHP will make available
     to the Client upon request a statement describing the Client's rights to
     compensation under the scheme.

DELEGATION AND USE OF AGENTS

37.  JOHP may delegate any of its functions under this Agreement to an Associate
     and may provide information about the Client and the Portfolio to any such
     Associate but JOHP's liability to the Client for all matters so delegated
     shall not be affected thereby.  JOHP shall give to the Client written
     notice of any delegation of a function which involves the exercise of its
     discretionary investment management powers.

38.  JOHP may employ agents (including Associates) to perform any
     administrative, dealing, custodial and ancillary services required to
     enable JOHP to perform its services under this Agreement.  JOHP undertakes
     to act in good faith and with due diligence in the choice and use of such
     agents.

TERMINATION OF AGREEMENT

39.  This Agreement may be terminated by either party by giving written notice
     of termination to the other at any time.  Termination shall take effect on
     the day upon which the other party actually receives the notice (the
     "Termination Date") provided that, where the Client is a joint account,
     notice of termination by JOHP shall be given to every person named in the
     joint account and in such circumstances the Termination Date shall be
     deemed to be the day after the date of posting by first class recorded
     delivery or other appropriate means to all persons named in the joint
     account.

40.  Upon the Termination Date, JOHP will complete expeditiously all
     transactions in progress at termination but will not execute any further
     transactions for the Client.  Upon all fees, commissions, expenses and
     other sums due to it and any other liabilities for which it may be or
     become liable in connection with the management of the Portfolio being
     settled or adequately secured to the satisfaction of JOHP, JOHP will ensure
     that all investments and cash balances held on the Client's behalf will,
     after any outstanding security registration, stock exchange settlements and
     other administrative matters have been completed and as soon as reasonably
     practicable, be transferred to the Client or dealt with in accordance with
     the Client's instructions, in all cases at the cost of the Client.


                                                           Page 104 of 258 Pages
<PAGE>
 
41.  Termination will not affect accrued rights, existing commitments or any
     contractual provision intended to survive termination and will be without
     penalty or other additional payment except that JOHP may charge the Client
     an amount equal to:

     (a)  the relevant proportion of the management fee, corresponding to that
          part of the period ending on a Valuation Date by reference to which
          fees are payable, which has expired when this Agreement is terminated;

     (b)  any additional expenses which JOHP necessarily incurs in terminating
          this Agreement; and

     (c)  any losses necessarily realised in settling or concluding outstanding
          obligations.

42.  The death, bankruptcy or other incapacity or, in the case of a body
     corporate, the cessation of business of the Client or a petition being
     presented or a meeting being convened to consider a resolution for the
     liquidation of the Client shall not of itself terminate JOHP's appointment;
     but JOHP may at its discretion treat its receipt of actual notice of any
     such events as if it were a written notice of termination from the Client.

43.  If the Client is a joint account the Client's obligations under this
     Agreement shall be joint and several.  On the death of any of the persons
     constituting the Client (being survived by any such other person), the
     Agreement shall not terminate and, except in the case of trustees, the
     interest of the deceased in the Portfolio shall automatically enure to the
     benefit of the survivor(s) unless otherwise specified by notice in writing
     to JOHP.

CLIENT WARRANTIES

44.  The Client warrants that the Client is the beneficial owner (or the duly
     authorised agent of the beneficial owner) of the whole of the Portfolio
     free from all liens, charges, encumbrances and restrictions on transfer
     except insofar as advised by the Client to JOHP, and will so remain during
     the currency of this Agreement.

45.  The Client warrants that the Client is empowered to enter into this
     Agreement without the consent or authority of any other party and in the
     case of a Client being a body corporate the Client warrants that by
     entering into this Agreement it is not nor will it be in breach of its
     Memorandum or Articles of Association or any other relevant document.

     force shall where the context so admits bear the same meaning in this
     Agreement.

47.  The Clause headings in this Agreement are included for ease of reference
     only and shall not affect its interpretation.

     the money comprised in the Portfolio will be invested provided that the
     services to be provided by JOHP will not include advising on or effecting
     Contingent Liability Transactions, nor will they, without the express prior
     authority of the Client, relate to options, futures or contracts for
     differences (or to any right or interest in such investments).


2.   The contents of the Portfolio may be invested in any market save for the
     following.


     There shall be no restriction on the amount of monies or proportion of the
     Portfolio invested in any one investment or type of investment permitted
     hereunder provided that, subject to the provisions relating to overdraft
     contained in paragraph 6 of this Agreement, under no circumstances will
     JOHP make investments on behalf of the Client to a value in excess of the
     aggregate of the value of the funds and securities held by JOHP on behalf
     of the Client in the accounts referred to in paragraph 16 of this
     Agreement.


            PART III - Risk Warnings and Risk Disclosure Statement



                                                           Page 107 of 258 Pages
<PAGE>
 
                 Investments Denominated in Foreign Currencies

If a liability of the Client in one currency is to be matched by an asset in a
different currency, or if JOHP provides services under this Agreement relating
to an investment denominated in a foreign currency, a movement in exchange rates
may have an effect which may be either favourable or unfavourable on the
investment, which effect may be separate from the gain or loss otherwise
experienced on such investment.

                      Investments not readily realisable

Certain categories of investments comprised in the Portfolio may not be readily
realisable.  You should be aware that there can be no certainty that market
makers or brokers will be prepared to deal in such investments and that proper
information for determining their current value may not be available.

                                   Warrants

A warrant is a right to subscribe for shares, debentures, loan stock or
government securities, and is exercisable against the original issuer of the
securities.  Warrants often involve a high degree of gearing so that a
relatively small movement in the price of the underlying security results in a
disproportionately large movement, unfavourable as well as favourable, in the
price of the warrant.  The prices of warrants can therefore be volatile.

                                 Stabilisation

This statement is made in compliance with Rule 14 of Chapter IV of the rules of
IMRO.

"We or our representatives may from time to time effect on your behalf or
recommend to you transactions in securities which are the subject of a recent
new issue where the price of those transactions may have been influenced by bids
made or transactions effected for the purpose of stabilising the price of those
securities.  You should read the explanation below carefully.  Its purpose is to
enable you to judge whether you wish your funds to be invested at all in such
securities or, if so, whether you wish to authorise us generally to effect
transactions in such securities on your behalf without further reference to you
or whether you wish to be consulted before any particular transaction is
effected on your behalf.

Stabilisation is a process whereby the market price of a security is pegged or
fixed during the period in which a new issue of securities is sold to the
public.  Stabilisation may take place in the new issue or in other securities
related to the new issue in such a way that the price of the other securities
may affect the price of the new issue or vice versa.

The reason stabilisation is permitted is that when a new issue is brought to
market the sudden glut will sometimes force the price lower for a period of time
before buyers are found for the securities on offer.

As long as he obeys a strict set of rules the "stabilising manager", normally
the issuing house chiefly responsible for bringing a new issue to market, is
entitled to buy securities in the market that he has previously sold to
investors or allotted to institutions who were included in 


                                                           Page 108 of 258 Pages
<PAGE>
 
the new issue but who have decided not to continue participating. The effect of
this may be to keep the price at a higher level than would otherwise be the case
during the period of stabilising.

The rules limit the period in which he may stabilise, fix the price at which he
may stabilise (in the case of shares and warrants but not bonds), and require
him to disclose that he may be (but not that he is) stabilising.

The fact that a new issue or a related security is being stabilised does not in
itself mean that investors are not interested in the issue, but neither should
the existence of transactions in an issue where stabilising may take place be
relied upon as an indication that investors are interested in the new issue or
interested in purchasing at the price at which transactions are taking place".

         19

BETWEEN:

(1)  J O HAMBRO & PARTNERS LIMITED ("JOHP")  a member of the Investment

     conduct of investment business by it, whose registered office is at 10 Park
     Place, London SW1A, 1LP; and

           --------------------------------------------------------
     Basingstoke, Hamps RG21 2SZ
     --------------------------------------------------------------    (address)

NOW IT IS HEREBY AGREED as follows:

APPOINTMENT AND STATUS OF CLIENT

1.   The Client, a Private Customer as defined in the Rules of IMRO, hereby
     appoints JOHP to act as discretionary investment manager, subject to the
     terms and conditions hereof, in relation to the Client's investments and
     cash which are from time to time placed under the management of JOHP (the
     "Portfolio") and JOHP hereby agrees to manage and administer the Portfolio.
     The appointment will commence on the date on which this Agreement is
     delivered to JOHP by the Client having been signed first by the Client then
     by JOHP. The assets comprising the Portfolio and their opening value are
     set out in Schedule 1.

MANAGEMENT OF INVESTMENTS

2.   JOHP shall have complete discretion, power and authority to manage the
     Portfolio and to make investments and changes in investments on the
     Client's behalf and as the Client's agent within the investment policy
     agreed between JOHP and the Client and set out in Part I of Schedule II.
     Such policy shall be subject to the guidelines and restrictions set out in
     Part II of Schedule II and to any guidelines, restrictions and instructions
     specified in writing from time to time by the Client or by the Client's
     duly authorised agent (written notice of whose authority shall have been
     received by JOHP.) The Client's attention is specifically drawn to the
     warnings set out in Part III of Schedule II.

                                                           Page 113 of 258 Pages
<PAGE>
 
3.   JOHP shall not be obliged to undertake the management of investments the
     management of which would in its opinion be onerous to it.

DEALING TERMS

4.   Subject as set out in paragraph 9, in effecting transactions for the
     Portfolio JOHP shall seek best execution at all times and may (subject to
     the investment policy set out in Part I of Schedule II) deal on such
     markets or exchanges and with such counterparties as it thinks fit.  The
     Client agrees that all such transactions will be effected in accordance
     with the rules and regulations of the relevant market or exchange and that
     JOHP may take all such steps as may be required or permitted by such rules
     and regulations and/or by good market practice.

5.   The Client's investments or documents of title or certificates evidencing
     title to investments or any other property belonging to the Client will not
     be lent by JOHP to a third party except as otherwise agreed between the
     Client and JOHP in writing.

6.   JOHP may supplement the funds in the Portfolio by borrowing on the Client's
     behalf but only for the purpose of funding short-term deficiencies arising
     in the normal course of JOHP's duties hereunder to an extent which is not
     material in the context of the Portfolio taken as a whole.  JOHP will not
     borrow money on the Client's behalf against the security of any of the
     Client's investments, documents of title or property.

7.   JOHP may commit the Client to underwrite any issue or offer for sale of
     securities without the Client's prior written consent.

8.   JOHP may act as principal in any transaction for the Client provided that
     JOHP shall secure for the Client best execution of such transaction.

9.   Subject to the IMRO Rules, JOHP may, without prior reference to the Client,
     enter into a transaction on behalf of more than one client collectively.

10.  JOHP has the right under this Agreement to effect transactions on the
     Client's behalf in investments the price of which may be being stabilised.
     The attention of the Client is referred to the statement contained in
     Schedule II relating to stabilisation.  Signature of this Agreement by or
     on behalf of the Client shall act as acknowledgment by the Client of
     receipt of such statement prior to entry into this Agreement.

CONFLICTS OF INTEREST

11.  Subject to paragraphs 12 and 13, JOHP shall not undertake any transactions
     on the Client's behalf in which JOHP has directly or indirectly a material
     interest or have any relationship with another party which may involve a
     conflict with JOHP's duty to the Client unless that interest or
     relationship is disclosed in writing to the Client.

12.  The Client's Portfolio may contain securities of which the issue or offer
     for sale is underwritten, managed or arranged by an Associate (as defined
     in the Rules of IMRO) of JOHP during the preceding twelve months.

                                                           Page 114 of 258 Pages
<PAGE>
 
13.  The Client understands that JOHP's directors or staff may from time to time
     hold shares or securities including holdings that may be in the Portfolio,
     and that JOHP's directors or staff may from time to time be directors of
     companies whose shares are held in the Portfolio.

14.  The Client acknowledges that JOHP may acquire or dispose of on the Client's
     behalf shares or units in any fund, company, trust or Collective Investment
     Scheme (as defined by the Rules of IMRO) under JOHP's management (or in a
     fund, company, trust or Collective Investment Scheme connected with JOHP)
     if JOHP considers such an investment to be appropriate for inclusion in or
     exclusion from the Portfolio.

CUSTODIAL SERVICES

15.  (a)  Save where the Client has notified JOHP in accordance with paragraph
          15(b), in those cases where the Client is situated in the United
          Kingdom registerable investments will be registered in the name of an
          Eligible Custodian (as defined in the Rules of IMRO) situated in the
          United Kingdom and nominated by JOHP.

     (b)  In those cases where the Client is situated overseas or where the
          Client so requests by notice in writing to JOHP, registerable
          investments will be registered in the name of an Eligible Custodian
          situated outside the United Kingdom and nominated by JOHP.

     (c)  All documents of title (including those in bearer form) will be
          retained in the custody of an Eligible Custodian nominated by JOHP and
          situated in the United Kingdom or overseas as applicable.

     (d)  None of the Eligible Custodians as aforesaid shall be Associates of
          JOHP.  However, the Client's registerable investments may at any time
          be registered in the name of a nominee company which is an Associate
          of JOHP and Client's documents of title may be held by that Associate
          at any time after JOHP shall have given the Client written notice of
          its intention to do so.  Such notice shall specify the nature of its
          association with such Associate.

ACCOUNTS, INTEREST AND DIVIDENDS

16.  The following Client accounts, together with such others that may be
     required, will be maintained by JOHP.

     (a)  INVESTMENT ACCOUNT

          The Client's investments will be held in this account.  Subject to
          paragraphs 5 and 6, JOHP shall not lend the Client's investments to
          any third party and shall not borrow money on the Client's behalf
          against the security of the Client's investments.

     (b)  CAPITAL ACCOUNT

                                                           Page 115 of 258 Pages
<PAGE>
 
          All uninvested cash will be held in this account by a bank chosen by
          JOHP.  The account will be debited with the cost of purchases on the
          Client's behalf and with sums due and payable by the Client to JOHP
          and will be credited with the net proceeds of sales on the Client's
          behalf.  Money drawn on behalf of the Client from the account shall
          not exceed the total of money held in the account on behalf of the
          Client at that time.  Interest will be paid on sums standing to the
          credit of the account and held on the Client's behalf at the
          prevailing market rate.  The interest will be paid quarterly and will
          be credited to the Income Account on the Client's behalf.

     (c)  SETTLEMENT ACCOUNT

          Money debited to the Capital Account in respect of the cost of
          purchases made on the Client's behalf and money received and
          receivable upon settlement of each sale made on the Client's behalf
          will be credited to this account and held there until the relevant
          settlement date.

     (d)  INCOME ACCOUNT

          Dividends and interest received on investments within the Portfolio
          will be credited to this account.  Balances on the account will be
          paid away quarterly in accordance with the Client's instructions or,
          in the absence of such instructions, will be transferred quarterly to
          the Capital Account as soon as reasonably practicable after the last
          day of each such quarter being 5th April, 30th June, 5th October and
          31st December in each year.  Money drawn on behalf of the Client from
          the account shall not exceed the total of money held in the account on
          behalf of the Client at that time.  Interest will not be paid on
          monies held in this account.

     (d)  OFF-SHORE FUNDS

          In those cases where the Client is situated overseas or if the Client
          notifies JOHP in writing that the Client wishes cash in the Portfolio
          to be held outside the United Kingdom, JOHP will be (subject to
          applicable laws and regulations) hold such cash in a bank account
          outside the United Kingdom.

17.  The Client may at any time instruct JOHP to realize any or all of the
     investments in the Portfolio and may withdraw any sum standing to the
     credit of the Capital Account and held on the Client's behalf.

18.  JOHP shall maintain separate ledger accounts on the Client's behalf.  All
     debits from and credits to the Investment Account and/or Capital Account
     and/or Income Account on the Client's behalf shall be recorded in the
     ledger accounts, and statements of account showing all transactions,
     payments and receipts up to and including 5th April of each year will be
     sent to the Client as soon as reasonably practicable after that date.

COMMUNICATIONS

<PAGE>
 
19.  In the interests of proper administration of the Portfolio and for related
     investment purposes JOHP, its representatives or employees, may call upon
     the Client by telephone, visit or otherwise communicate orally with the
     Client without express invitation.  The Client's attention is drawn to the
     fact that the Client will forfeit any right conferred by section 56 of the
     Financial Services Act 1986 to treat as unenforceable any investment
     agreement entered into in the course of or in consequence of such a call.

ADMINISTRATION

20.  Contract notes in respect of every purchase and sale on the Client's behalf
     will be sent to the Client before the close of business on the day next
     following the day on which the transaction was effected.

21.  JOHP will on the Client's request forward details of all transactions on
     the Client's behalf to the Client's tax advisor without additional charge.

22.  The Client may (upon giving reasonable notice) inspect all copy contract
     notes, vouchers and copies of entries in books or electronic recording
     media kept by JOHP or to which JOHP has access relating to the transactions
     effected by JOHP on the Client's behalf and those records will be
     maintained by JOHP or JOHP will ensure that they are maintained for not
     less than seven years from the date of the relevant transaction.

23.  All documents will be sent to the Client at the address given above unless
     and until otherwise directed in writing.  The Client agrees that it will
     immediately notify JOHP in writing of any changes of address, and that JOHP
     will not be responsible for any consequences which may arise from failure
     to do so.

REVIEWS AND VALUATIONS

24.  JOHP will prepare reviews of the Portfolio incorporating an up-to-date
     valuation of each investment comprised in the Portfolio and a statement of
     the basis on which it was valued on a six monthly basis or at such other
     frequency as may be agreed between JOHP and the Client.  Such reviews shall
     be prepared as at such half yearly or other dates as shall be agreed
     between JOHP and the Client from time to time (each such date being
     referred to as a "Valuation Date"), and JOHP will send such reviews to the
     Client within twenty-five business days of each Valuation Date

25.  On each Valuation Date cash will be valued at its face value and each
     investment will be valued at its middle market price on the relevant stock
     exchange at the close of business on such day or (if not a business day) on
     the nearest prior business day as is supplied by "Exshare" or any other
     suitable information service chosen by JOHP (which figures shall be binding
     save for manifest error).  For the purpose of valuing in sterling any
     foreign currency or any security listed on a foreign stock exchange the
     price of which is quoted in currency other than sterling, the valuation and
     middle market exchange rates supplied by "Exshare" or any other suitable
     information service chosen by JOHP shall be applied.  In the absence of
     that valuation or exchange rate, the middle market price as determined by
     the Daily Official List of The Stock 

                                                           Page 117 of 258 Pages
<PAGE>
 
     Exchange or the equivalent list for any relevant stock exchange will be
     applied. If none of the foregoing methods of valuation are available, the
     investments in question will be valued in such other manner (by JOHP or
     such other person selected by JOHP) as shall in JOHP's opinion be fair.

26.  JOHP accepts no liability for any period longer than 25 business days
     between any Valuation Date and the despatch of a review to the Client of
     his Portfolio which has elapsed as result of any act or omission of any
     third party.

VOTING AND OTHER RIGHTS

27.  JOHP will be entitled at its discretion and without notice to the Client to
     procure or to refrain from procuring the exercise of voting and other
     rights and privileges attaching to the investments comprised in the
     Portfolio and to accede or refrain from acceding to any compromise or
     arrangement in relation to any scheme of arrangement or scheme for
     reconstruction or amalgamation involving any such investment.  JOHP will
     not forward to the Client any circulars, notices or proxy cards received in
     respect to investments comprised in the Portfolio.

FEES, COMMISSIONS AND EXPENSES

28.  (a)  The Client will pay a management fee to JOHP in respect of the period
          beginning with first receipt by JOHP of any investments or money from
          the Client and ending with a Valuation Date (as defined in paragraph
          24) and each period thereafter starting with the day after any
          Valuation Date and ending on the next Valuation Date (or the
          Termination Date as defined in paragraph 39 if sooner).

     (b)  The management fee shall be calculated in accordance with the 'Scale
          Rates and Charges' set out in Schedule III.

     (c)  The management fee shall be payable not later than 14 days after
          despatch to the Client of an invoice which shall be sent to the Client
          as soon as is reasonably practicable after each Valuation Date.
          Unless otherwise instructed the Client's Capital Account will be
          debited with the amounts due to JOHP on the 14th day after despatch of
          such invoice.

     (d)  In addition the Client shall reimburse JOHP for any expenses or
          liabilities which it may incur in properly carrying out its duties
          hereunder.

29.  The management fee shall be deemed to have accrued on a day-to-day basis,
     so that, if this Agreement commences or terminates other than on a
     Valuation Date (as defined in paragraph 24), the amount of the fee shall be
     duly apportioned.

30.  Commissions (as set out in Schedule III) will be payable by the Client on
     purchases and sales of investments together will all expenses including
     stamp duties, stamp duty reserve tax and VAT thereon (if applicable).  The
     Client recognizes that JOHP may gain a commission benefit from dealing in a
     bulk purchase or sale on behalf of JOHP's

     clients, one of whom may be the Client, or from return commissions which
     benefit JOHP shall be entitled to retain. JOHP will be free to accept and
     retain as an addition to its fees and commissions any other commissions
     which it receives in the course of its dealing on the Client's behalf: all
     such benefits and receipts shall supplement any other remuneration
     receivable by JOHP in connection with transactions effected by JOHP with or
     for the Client under this or any other agreement with the Client and the
     Client consents to all such benefits and receipts as are referred to above
     without prior disclosure of the same to the Client on a case-by-case basis
     provided that JOHP undertakes to secure for the Client best execution of
     all transactions effected with or through a party from whom JOHP receives
     such benefits and commissions, disregarding any benefit which the Client
     might obtain directly or indirectly as a result of such arrangements.

31.  JOHP shall be entitled to alter the manner of computing or charging its
     fees, commissions and expenses or of paying interest on the money held on
     the Client's behalf in the Capital Account (including with prejudice to the
     generality of the foregoing its scale rates and charges) by giving one
     month's prior notice in writing to the Client.

RESPONSIBILITY AND INSURANCE

32.  JOHP will indemnify the Client in respect of any loss incurred as a result
     of negligence, wilful default or fraud by JOHP or any of its employees.
     Subject to the above, JOHP will not be responsible or liable for any claim,
     loss, damage, expense or costs arising by reason of any of the following:

     (a)  any investment decision taken and acted upon in accordance with the
          terms of this Agreement; or

     (b)  any delay or default in the performance of its obligations under this
          Agreement arising in consequence of any event or circumstance beyond
          the reasonable control of JOHP; or

     (c)  any act or omission on the part of any of the banks or nominee
          companies controlled by them or other eligible custodians as referred
          to in paragraph 15 or any other person to which any of them shall have
          delegated its function or on the part of any other third party
          whatsoever; or

     (d)  any consequential loss suffered in consequence of any act or omission
          of JOHP or any breach of JOHP of any term of this Agreement.

33.  The Client agrees to indemnify and keep indemnified JOHP from and against
     all demands, claims, liabilities, losses, damages, costs and expenses
     whatsoever incurred by JOHP arising out of the breach by the Client of any
     warranty or by reason of any failure by the Client to comply with and/or
     perform any of the terms and conditions in this Agreement.

<PAGE>
 
34.  Where the Client is a joint account (whether or not a trust account) JOHP
     shall unless and until otherwise directed in writing by all the persons
     named in the joint account, be entitled to act on the instructions of any
     of them and shall not in any whatsoever be liable to the others for doing
     so.

35.  JOHP has effected insurance to provide for the protection of the Client
     against losses arising from any negligence of JOHP or any dishonesty of
     employees of JOHP.

36.  Under Section 54 of the Financial Services Act 1986 The Securities and
     Investments Board has established a scheme for compensating investors by
     which the Client may be entitled to compensation in the event of JOHP's
     inability to meet any liabilities to the Client.  JOHP will make available
     to the Client upon request a statement describing the Client's rights to
     compensation under the scheme.

DELEGATION AND USE OF AGENTS

37.  JOHP my delegate any of its functions under this Agreement to an Associate
     and may provide information about the Client and the Portfolio to any such
     Associate but JOHP's liability to the Client for all matters so delegated
     shall not be affected thereby.  JOHP shall give to the Client written
     notice of any delegation of a function which involves the exercise of its
     discretionary investment management powers.

38.  JOHP may employ agents (including Associates) to perform any
     administrative, dealing, custodial and ancillary services required to
     enable JOHP to perform its services under this Agreement.  JOHP undertakes
     to act in good faith and with due diligence in the choice and use of such
     agents.

TERMINATION OF AGREEMENT

39.  This Agreement may be terminated by either party by giving written notice
     of termination to the other at any time.  Termination shall take effect on
     the day upon which the other party actually receives the notice (the
     "Termination Date") provided that, where the Client is a joint account,
     notice of termination by JOHP shall be given to every person named in the
     joint account and in such circumstances the Termination Date shall be
     deemed to be the day after the date of posting by first class recorded
     delivery or other appropriate means to all persons named in the joint
     account.

40.  Upon the Termination Date, JOHP will complete expeditiously all
     transactions in progress at termination but will not execute any further
     transactions for the Client.  Upon all fees, commissions, expenses and
     other sums due to it and any other liabilities for which it may be or
     become liable in connection with the management of the Portfolio being
     settled or adequately secured to the satisfaction of JOHP, JOHP will ensure
     that all investments and cash balances held on the Client's behalf will,
     after any outstanding security registration, stock exchange settlements and
     other administrative matters have been completed and as soon as reasonably
     practicable, be transferred to the Client or dealt with in accordance with
     the Client's instructions, in all cases at the cost of the Client.

<PAGE>
 
41.  Termination will not affect accrued rights, existing commitments or any
     contractual provision intended to survive termination and will be without
     penalty or other additional payment except that JOHP may charge the Client
     an amount equal to:

     (a)  the relevant proportion of the management fee, corresponding to that
          part of the period ending on a Valuation Date by reference to which
          fees are payable, which has expired when this Agreement is terminated;

     (b)  any additional expenses which JOHP necessarily incurs in terminating
          this Agreement; and

     (c)  any losses necessarily realized in settling or concluding outstanding
          obligations.

42.  The death, bankruptcy or other incapacity or, in the case of a body
     corporate, the cessation of business of the Client or a petition being
     presented or a meeting being convened to consider a resolution for the
     liquidation of the Client shall not of itself terminate JOHP's appointment;
     but JOHP may at its discretion treat its receipt of actual notice of any
     such events as if it were a written notice of termination from the Client.

43.  If the Client is a joint account the Client's obligations under this
     Agreement shall be joint and several.  On the death of any of the persons
     constituting the Client (being survived by any such other person), the
     Agreement shall not terminate and, except in the case of trustees, the
     interest of the deceased in the Portfolio shall automatically enure to the
     benefit of the survivor(s) unless otherwise specified by notice in writing
     to JOHP.

CLIENT WARRANTIES

44.  The Client warrants that the Client is the beneficial owner (or the duly
     authorized agent of the beneficial owner) of the whole of the Portfolio
     free from all liens, charges, encumbrances and restrictions on transfer
     except insofar as advised by the Client to JOHP, and will so remain during
     the currency of this Agreement.

45.  The Client warrants that the Client is empowered to enter into this
     Agreement without the consent or authority of any other party and in the
     case of a Client being a body corporate the Client warrants that by
     entering into this Agreement it is not nor will it be in breach of its
     Memorandum or Articles of Association or any other relevant document.

                                  SCHEDULE I

                                 THE PORTFOLIO

                    Valuation and composition of Portfolio
          (see attached letter/opening valuation - where applicable)

                                  SCHEDULE II

                INVESTMENT POLICY, GUIDELINES AND RESTRICTIONS

                  PART I - Investment Policy including basis
                         of measurement of performance

The investment objectives are to maintain a maximum total return commensurate
with safety and the protection of the underlying value of the capital of the
fund.


The performance will be measured against the F.T. All Share Index, any other
appropriate Index or measure of performance agreed upon by JOHP and the Client.

                    PART II -  Guidelines and Restrictions

1.   There will be no restrictions placed on the types of investment in which
     the money comprised in the Portfolio will be invested provided that the
     services to be provided by JOHP will not include advising on or effecting
     Contingent Liability Transactions, nor will they, without the express prior
     authority of the Client, relate to options, futures or contracts for
     differences (or to any right or interest in such investments).

2.   The contents of the Portfolio may be invested in any market save for the
     following.

     There shall be no restriction on the amount of monies or proportion of the
     Portfolio invested in any one investment or type of investment permitted
     hereunder provided that, subject to the provisions relating to overdraft
     contained in paragraph 6 of this Agreement, under no circumstances will
     JOHP make investment on behalf of the Client to a value in excess of the
     aggregate of the value of the funds and securities held by JOHP on behalf
     of the Client in the accounts referred to in paragraph 16 of this
     Agreement.

            PART III - Risk Warnings and Risk Disclosure Statement

                 Investments denominated in foreign Currencies

If a liability of the Client in one currency is to be matched by an asset in a
different currency, or if JOHP provides services under this Agreement relating
to any investment denominated in a foreign currency, a movement in exchange
rates may have an effect which may be either favorable or unfavorable on the
investment, which effect may be separate from the gain or loss otherwise
experienced on such investment.

                       Investments not readily realisable

Certain categories of investments comprised in the Portfolio may not be readily
realisable.  You should be aware that there can be no certainty that market
makers or brokers will be prepared to deal in such investments and that proper
information for determining their current value may not be available.

                                    Warrants

A warrant is a right to subscribe for shares, debentures, loan stock or
government securities, and is exercisable against the original issuer of the
securities.  Warrants often involve a high degree of gearing so that a
relatively small movement in the price of the underlying security results in a
disproportionately large movement, unfavorable as well as favorable, in the
price of the warrant.  The prices of warrants can therefore be volatile.

                                 Stabilisation

This statement is made in compliance with Rule 14 of Chapter IV of the rules of
IMRO.

"We or our representatives may from time to time effect on your behalf or
recommend to you transactions in securities which are the subject of a recent
new issue where the price of those transactions may have been influenced by bids
made or transactions effected for the purpose of stabilising the price of those
securities.  You should read the explanation below carefully.  Its purpose is to
enable you to judge whether you wish your funds to be invested at all in such
securities or, if so, whether you wish to authorize us generally to effect
transaction in such securities on your behalf without further reference to you
or whether you wish to be consulted before any particular transaction in
effected on your behalf.

Stabilisation is a process whereby the market price of a security is pegged or
fixed during the period in which a new issue of securities is sold to the
public.  Stabilisation may take place in the new issue or in other securities
related to the new issue in such a way that the price of the other securities
may affect the price of the new issue or vice versa.

The reason stabilisation is permitted is that when a new issue is brought to
market the sudden glut will sometimes force the price lower for a period of time
before buyers are found for the securities on offer.

As long as he obeys a strict set of rules the "stabilising manager", normal the
issuing house chiefly responsible for bringing a new issue to market, is
entitled to buy securities in the market that he has previously sold to
investors or allotted to institutions who were included in the new issue but who
have decided not to continue participating.  The effect of this may be to keep
the price at a higher level than would otherwise be the case during the period
of stabilising.

The rules limit the period in which he may stabilise, fix the price at which he
may stabilize (in the case of shares and warrants but not bonds), and require
him to disclose that he may be (but not that he is) stabilising.



                                                           Page 124 of 258 Pages

<PAGE>
 
The fact that a new issue or a related security is being stabilised does not in
itself mean that investors are not interested in the issue, but neither should
the existence of transactions in an issue where stabilising may take place be
relied upon as an indication that investors are interest in the new issue or
interested in purchasing at the price at which transactions are taking place".

(address)
NOW IT IS HEREBY AGREED as follows:

APPOINTMENT AND STATUS OF CLIENT

1.   The Client, a Private Customer as defined in the Rules of IMRO, hereby
     appoints JOHP to act as discretionary investment manager, subject to the
     terms and conditions hereof, in relation to the Client's investments and
     cash which are from time to time placed under the management of JOHP (the
     "Portfolio") and JOHP hereby agrees to manage and administer the Portfolio.
     The appointment will commence on the date on which this Agreement is
     delivered to JOHP by the Client having been signed first by the Client then
     by JOHP.  The assets comprising the Portfolio and their opening value are
     set out in Schedule 1.

MANAGEMENT OF INVESTMENTS

2.   JOHP shall have complete discretion, power and authority to manage the
     Portfolio and to make investments and changes in investments on the
     Client's behalf and as the Client's agent within the investment policy
     agreed between JOHP and the Client and set out in Part 1 of Schedule II.
     Such policy shall be subject to the guidelines and restrictions set out in
     Part II of Schedule II and to any guidelines, restrictions and instructions
     specified in writing from time to time by the Client or by the Client's
     duly authorized agent (written notice of whose authority shall have been
     received by JOHP).  The Client's attention is specifically drawn to the
     warnings set out in Part III of Schedule II.

<PAGE>
 
3.   JOHP shall not be obliged to undertake the management of investments the
     management of which would in its opinion be onerous to it.

DEALING TERMS

4.   Subject as set out in paragraph 9, in effecting transactions for the
     Portfolio JOHP shall seek best execution at all times and may (subject to
     the investment policy set out in Part I of Schedule II) deal on such
     markets or exchanges and with such counterparties as it thinks fit.  The
     Client agrees that all such transactions will be effected in accordance
     with the rules and regulations of the relevant market or exchange and that
     JOHP may take all such steps as may be required or permitted by such rules
     and regulations and/or by good market practice.

5.   The Client's investments or documents of title or certificates evidencing
     title to investments or any other property belonging to the Client will not
     be lent by JOHP to a third party except as otherwise agreed between the
     Client and JOHP in writing.

6.   JOHP may supplement the funds in the Portfolio by borrowing on the Client's
     behalf but only for the purpose of funding short-term deficiencies arising
     in the normal course of JOHP's duties hereunder to an extent which is not
     material in the context of the Portfolio taken as a whole.  JOHP will not
     borrow money on the Client's behalf against the security of any of the
     Client's investments, documents of title or property.

7.   JOHP may commit the Client to underwrite any issue or offer for sale of
     securities without the Client's prior written consent.

8.   JOHP may act as principal in any transaction for the Client provided that
     JOHP shall secure for the Client best execution of such transaction.

9.   Subject to the IMRO Rules, JOHP may, without prior reference to the Client,
     enter into a transaction on behalf of more than one client collectively.

10.  JOHP has the right under this Agreement to effect transactions on the
     Client's behalf in investments the price of which may be being stabilized.
     The attention of the Client is referred to the statement contained in
     Schedule II relating to stabilization.  Signature of this Agreement by or
     on behalf of the Client shall act as acknowledgment by the Client of
     receipt of such statement prior to entry into this Agreement.

CONFLICTS OF INTEREST

11.  Subject to paragraphs 12 and 13, JOHP shall not undertake any transactions
     on the Client's behalf in which JOHP has directly or indirectly a material
     interest or have any relationship with another party which may involve a
     conflict with JOHP's duty to the Client unless that interest or
     relationship is disclosed in writing to the Client.

12.  The Client's Portfolio may contain securities of which the issue or offer
     for sale is underwritten, managed or arranged by an Associate (as defined
     in the Rules of IMRO) of JOHP during the preceding twelve months.


                                                           Page 130 of 258 Pages
<PAGE>
 
13.  The Client understands that JOHP's directors or staff may from time to time
     hold shares or securities including holdings that may be in the Portfolio,
     and that JOHP's directors or staff may from time to time be directors of
     companies whose shares are held in the Portfolio.

14.  The Client acknowledges that JOHP may acquire or dispose of on the Client's
     behalf shares or units in any fund, company, trust or Collective Investment
     Scheme (as defined by the Rules of IMRO) under JOHP's management (or in a
     fund, company, trust or Collective Investment Scheme connected with JOHP)
     if JOHP considers such an investment to be appropriate for inclusion in or
     exclusion from the Portfolio.

CUSTODIAL SERVICES

15.  (a)  Save where the Client has notified JOHP in accordance with paragraph
          15(b), in those  cases where the Client is situated in the United
          Kingdom registerable investments will be registered in the name of an
          Eligible Custodian (as defined in the Rules of IMRO) situated in the
          United Kingdom and nominated by JOHP.

     (b)  In those cases where the Client is situated overseas or where the
          Client so requests by notice in writing to JOHP, registerable
          investments will be registered in the name of an Eligible Custodian
          situated outside the United Kingdom and nominated by JOHP.

     (c)  All documents of title (including those in bearer form) will be
          retained in the custody of an Eligible Custodian nominated by JOHP and
          situated in the United Kingdom or overseas as applicable.

     (d)  None of the Eligible Custodians as aforesaid shall be Associates of
          JOHP.  However, the Client's registerable investments may at any time
          be registered in the name of a nominee company which is an Associate
          of JOHP and Client's documents of title may be held by that Associate
          at any time after JOHP shall have given the Client written notice of
          its intention to do so.  Such notice shall specify the nature of its
          association with such Associate.

ACCOUNTS, INTEREST AND DIVIDENDS

16.  The following Client accounts, together with such others that may be
     required, will be maintained by JOHP.

     (a)  INVESTMENT ACCOUNT

          The Client's investments will be held in this account.  Subject to
          paragraphs 5 and 6, JOHP shall not lend the Client's investments to
          any third party and shall not borrow money on the Client's behalf
          against the security of the Client's investments.

     (b)  CAPITAL ACCOUNT


                                                           Page 131 of 258 Pages
<PAGE>
 
          All uninvested cash will be held in this account by a bank chosen by
          JOHP.  The account will be debited with the cost of purchases on the
          Client's behalf and with sums due and payable by the Client to JOHP
          and will be credited with the net proceeds of sales on the Client's
          behalf.  Money drawn on behalf of the Client from the account shall
          not exceed the total of money held in the account on behalf of the
          Client at that time.  Interest will be paid on sums standing to the
          credit of the account and held on the Client's behalf at the
          prevailing market rate.  The interest will be paid quarterly and will
          be credited to the Income Account on the Client's behalf.

     (c)  SETTLEMENT ACCOUNT

          Money debited to the Capital Account in respect of the cost of
          purchases made on the Client's behalf and money received and
          receivable upon settlement of each sale made on the Client's behalf
          will be credited to this account and held there until the relevant
          settlement date.

     (d)  INCOME ACCOUNT

          Dividends and interest received on investments within the Portfolio
          will be credited to this account.  Balances on the account will be
          paid away quarterly in accordance with the Client's instructions or,
          in the absence of such instructions, will be transferred quarterly to
          the Capital Account as soon as reasonably practicable after the last
          day of each such quarter being 5th April, 30th June, 5th October and
          31st December in each year.  Money drawn on behalf of the Client from
          the account shall not exceed the total of money held in the account on
          behalf of the Client at that time.  Interest will not be paid on
          monies held in this account.

     (d)  OFF-SHORE FUNDS

          In those cases where the Client is situated overseas or if the Client
          notifies JOHP in writing that the Client wishes cash in the Portfolio
          to be held outside the United Kingdom, JOHP will be (subject to
          applicable laws and regulations) hold such cash in a bank account
          outside the United Kingdom

17.  The Client may at any time instruct JOHP to realise any or all of the
     investments in the Portfolio and may withdraw any sum standing to the
     credit of the Capital Account and held on the Client's behalf.

18.  JOHP shall maintain separate ledger accounts on the Client's behalf.  All
     debits from and credits to the Investment Account and/or Capital Account
     and/or Income Account on the Client's behalf shall be recorded in the
     ledger accounts, and statements of account showing all transactions,
     payments and receipts up to and including 5th April of each year will be
     sent to the Client as soon as reasonably practicable after that date.

<PAGE>
 
19.  In the interests of proper administration of the Portfolio and for related
     investment purposes JOHP, its representatives or employees, may call upon
     the Client by telephone, visit or otherwise communicate orally with the
     Client without express invitation.  The Client's attention is drawn to the
     fact that the Client will forfeit any right conferred by section 56 of the
     Financial Services Act 1986 to treat as unenforceable any investment
     agreement entered into in the course of or in consequence of such a call.

ADMINISTRATION

20.  Contract notes in respect of every purchase and sale on the Client's behalf
     will be sent to the Client before the close of business on the day next
     following the day on which the transaction was effected.

21.  JOHP will on the Client's request forward details of all transactions on
     the Client's behalf to the Client's tax advisor without additional charge.

22.  The Client may (upon giving reasonable notice) inspect all copy contract
     notes, vouchers and copies of entries in books or electronic recording
     media kept by JOHP or to which JOHP has access relating to the transactions
     effected by JOHP on the Client's behalf and those records will be
     maintained by JOHP or JOHP will ensure that they are maintained for not
     less than seven years from the date of the relevant transaction.

23.  All documents will be sent to the Client at the address given above unless
     and until otherwise directed in writing.  The Client agrees that it will
     immediately notify JOHP in writing of any changes of address, and that JOHP
     will not be responsible for any consequences which may arise from failure
     to do so.

REVIEWS AND VALUATIONS

24.  JOHP will prepare reviews of the Portfolio incorporating an up-to-date
     valuation of each investment comprised in the Portfolio and a statement of
     the basis on which it was valued on a six monthly basis or at such other
     frequency as may be agreed between JOHP and the Client.  Such reviews shall
     be prepared as at such half yearly or other dates as shall be agreed
     between JOHP and the Client from time to time (each such date being
     referred to as a "Valuation Date"), and JOHP will send such reviews to the
     Client within twenty-five business days of each Valuation Date.

25.  On each Valuation Date cash will be valued at its face value and each
     investment will be valued at its middle market price on the relevant stock
     exchange at the close of business on such day or (if not a business day) on
     the nearest prior business day as is supplied by "Exshare" or any other
     suitable information service chosen by JOHP (which figures shall be binding
     save for manifest error).  For the purpose of valuing in sterling any
     foreign currency or any security listed on a foreign stock exchange the
     price of which is quoted in currency other than sterling, the valuation and
     middle market exchange rates supplied by "Exshare" or any other suitable
     information service chosen by JOHP shall be applied.  In the absence of
     that valuation or exchange rate, the middle market price as determined by
     the Daily Official List of The Stock 


                                                           Page 133 of 258 Pages
<PAGE>
 
     Exchange or the equivalent list for any relevant stock exchange will be
     applied. If none of the foregoing methods of valuation are available, the
     investments in question will be valued in such other manner (by JOHP or
     such other person selected by JOHP) as shall in JOHP's opinion be fair.

26.  JOHP accepts no liability for any period longer than 25 business days
     between any Valuation Date and the despatch of a review to the Client of
     his Portfolio which has elapsed as a result of any act or omission of any
     third party.

VOTING AND OTHER RIGHTS

27.  JOHP will be entitled at its discretion and without notice to the Client to
     procure or to refrain from procuring the exercise of voting and other
     rights and privileges attaching to the investments comprised in the
     Portfolio and to accede or refrain from acceding to any compromise or
     arrangement in relation to any scheme of arrangement or scheme for
     reconstruction or amalgamation involving any such investment.  JOHP will
     not forward to the Client any circulars, notices or proxy cards received in
     respect of investments comprised in the Portfolio.

FEES, COMMISSIONS AND EXPENSES

28.  (a)  The Client will pay a management fee to JOHP in respect of the period
          beginning with first receipt by JOHP of any investments or money from
          the Client and ending with a Valuation Date (as defined in paragraph
          24) and each period thereafter starting with the day after any
          Valuation Date and ending on the next Valuation Date (or the
          Termination Date as defined in paragraph 39 if sooner).

     (b)  The management fee shall be calculated in accordance with the 'Scale
          Rates and Charges' set out in Schedule III.

     (c)  The management fee shall be payable not later than 14 days after
          despatch to the Client of an invoice which shall be sent to the Client
          as soon as is reasonably practicable after each Valuation Date.
          Unless otherwise instructed the Client's Capital Account will be
          debited with the amounts due to JOHP on the 14th day after despatch of
          such invoice.

     (d)  In addition the Client shall reimburse JOHP for any expenses or
          liabilities which it may incur in properly carrying out its duties
          hereunder.

29.  The management fee shall be deemed to have accrued on a day-to-day basis,
     so that, if this Agreement commences or terminates other than on a
     Valuation Date (as defined in paragraph 24), the amount of the fee shall be
     duly apportioned.

30.  Commissions (as set out in Schedule III) will be payable by the Client on
     purchases and sales of investments together with all expenses including
     stamp duties, stamp duty reserve tax and VAT thereon (if applicable).  The
     Client recognises that JOHP may gain a commission benefit from dealing in a
     bulk purchase or sale on behalf of JOHP's 


                                                           Page 134 of 258 Pages

<PAGE>
 
     clients, one of whom may be the Client, or from return commissions which
     benefit JOHP shall be entitled to retain. JOHP will be free to accept and
     retain as an addition to its fees and commissions any other commissions
     which it receives in the course of its dealing on the Client's behalf: all
     such benefits and receipts shall supplement any other remuneration
     receivable by JOHP in connection with transactions effected by JOHP with or
     for the Client under this or any other agreement with the Client and the
     Client consents to all such benefits and receipts as are referred to above
     without prior disclosure of the same to the Client on a case-by-case basis
     provided that JOHP undertakes to secure for the Client best execution of
     all transactions effected with or through a party from whom JOHP receives
     such benefits and commissions, disregarding any benefit which the Client
     might obtain directly or indirectly as a result of such arrangements.

31.  JOHP shall be entitled to alter the manner of computing or charging its
     fees, commissions and expenses or of paying interest on the money held on
     the Client's behalf in the Capital Account (including with prejudice to the
     generality of the foregoing its scale rates and charges) by giving one
     month's prior notice in writing to the Client.

RESPONSIBILITY AND INSURANCE

32.  JOHP will indemnify the Client in respect of any loss incurred as a result
     of negligence, wilful default or fraud by JOHP or any of its employees.
     Subject to the above, JOHP will not be responsible or liable for any claim,
     loss, damage, expense or costs arising by reason of any of the following:

     (a)  any investment decision taken and acted upon in accordance with the
          terms of this Agreement; or

     (b)  any delay or default in the performance of its obligations under this
          Agreement arising in consequence of any event or circumstance beyond
          the reasonable control of JOHP; or

     (c)  any act or omission on the part of any of the banks or nominee
          companies controlled by them or other eligible custodians as referred
          to in paragraph 15 or any other person to which any of them shall have
          delegated its function or on the part of any other third party
          whatsoever; or

     (d)  any consequential loss suffered in consequence of any act or omission
          of JOHP or any breach of JOHP of any term of this Agreement.

33.  The Client agrees to indemnify and keep indemnified JOHP from and against
     all demands, claims, liabilities, losses, damages, costs and expenses
     whatsoever incurred by JOHP arising out of the breach by the Client of any
     warranty or by reason of any failure by the Client to comply with and/or
     perform any of the terms and conditions contained in this Agreement.

<PAGE>
 
34.  Where the Client is a joint account (whether or not a trust account) JOHP
     shall unless and until otherwise directed in writing by all the persons
     named in the joint account, be entitled to act on the instructions of any
     of them and shall not in any whatsoever be liable to the others for doing
     so.

35.  JOHP has effected insurance to provide for the protection of the Client
     against losses arising from any negligence of JOHP or any dishonesty of
     employees of JOHP.

36.  Under Section 54 of the Financial Services Act 1986 The Securities and
     Investments Board has established a scheme for compensating investors by
     which the Client may be entitled to compensation in the event of JOHP's
     inability to meet any liabilities to the Client.  JOHP will make available
     to the Client upon request a statement describing the Client's rights to
     compensation under the scheme.

DELEGATION AND USE OF AGENTS

37.  JOHP may delegate any of its functions under this Agreement to an Associate
     and may provide information about the Client and the Portfolio to any such
     Associate but JOHP's liability to the Client for all matters so delegated
     shall not be affected thereby.  JOHP shall give to the Client written
     notice of any delegation of a function which involves the exercise of its
     discretionary investment management powers.

38.  JOHP may employ agents (including Associates) to perform any
     administrative, dealing, custodial and ancillary services required to
     enable JOHP to perform its services under this Agreement.  JOHP undertakes
     to act in good faith and with due diligence in the choice and use of such
     agents.

TERMINATION OF AGREEMENT

39.  This Agreement may be terminated by either party by giving written notice
     of termination to the other at any time.  Termination shall take effect on
     the day upon which the other party actually receives the notice (the
     "Termination Date") provided that, where the Client is a joint account,
     notice of termination by JOHP shall be given to every person named in the
     joint account and in such circumstances the Termination Date shall be
     deemed to be the day after the date of posting by first class recorded
     delivery or other appropriate means to all persons named in the joint
     account.

40.  Upon the Termination Date, JOHP will complete expeditiously all
     transactions in progress at termination but will not execute any further
     transactions for the Client.  Upon all fees, commissions, expenses and
     other sums due to it and any other liabilities for which it may be or
     become liable in connection with the management of the Portfolio being
     settled or adequately secured to the satisfaction of JOHP, JOHP will ensure
     that all investments and cash balances held on the Client's behalf will,
     after any outstanding security registration, stock exchange settlements and
     other administrative matters have been completed and as soon as reasonably
     practicable, be transferred to the Client or dealt with in accordance with
     the Client's instructions, in all cases at the cost of the Client.


                                                           Page 136 of 258 Pages

<PAGE>
 
41.  Termination will not affect accrued rights, existing commitments or any
     contractual provision intended to survive termination and will be without
     penalty or other additional payment except that JOHP may charge the Client
     an amount equal to:

     (a)  the relevant proportion of the management fee, corresponding to that
          part of the period ending on a Valuation Date by reference to which
          fees are payable, which has expired when this Agreement is terminated;

     (b)  any additional expenses which JOHP necessarily incurs in terminating
          this Agreement; and

     (c)  any losses necessarily realised in settling or concluding outstanding
          obligations.

42.  The death, bankruptcy or other incapacity or, in the case of a body
     corporate, the cessation of business of the Client or a petition being
     presented or a meeting being convened to consider a resolution for the
     liquidation of the Client shall not of itself terminate JOHP's appointment;
     but JOHP may at its discretion treat its receipt of actual notice of any
     such events as if it were a written notice of termination from the Client.

43.  If the Client is a joint account the Client's obligations under this
     Agreement shall be joint and several.  On the death of any of the persons
     constituting the Client (being survived by any such other person), the
     Agreement shall not terminate and, except in the case of trustees, the
     interest of the deceased in the Portfolio shall automatically enure to the
     benefit of the survivor(s) unless otherwise specified by notice in writing
     to JOHP.

CLIENT WARRANTIES

44.  The Client warrants that the Client is the beneficial owner (or the duly
     authorised agent of the beneficial owner) of the whole of the Portfolio
     free from all liens, charges, encumbrances and restrictions on transfer
     except insofar as advised by the Client to JOHP, and will so remain during
     the currency of this Agreement.

45.  The Client warrants that the Client is empowered to enter into this
     Agreement without the consent or authority of any other party and in the
     case of a Client being a body corporate the Client warrants that by
     entering into this Agreement it is not nor will it be in breach of its
     Memorandum or Articles of Association or any other relevant document.

     Agreement.

     only and shall not affect its interpretation.

1.   There will be no restrictions placed on the types of investment in which
     the money comprised in the Portfolio will be invested provided that the
     services to be provided by JOHP will not include advising on or effecting
     Contingent Liability Transactions, nor will they, without the express prior
     authority of the Client, relate to options, futures or contracts for
     differences (or to any right or interest in such investments).


2.   The contents of the Portfolio may be invested in any market save for the
     following.


     There shall be no restriction on the amount of monies or proportion of the
     Portfolio invested in any one investment or type of investment permitted
     hereunder provided that, subject to the provisions relating to overdraft
     contained in paragraph 6 of this Agreement, under no circumstances will
     JOHP make investments on behalf of the Client to a value in excess of the
     aggregate of the value of the funds and securities held by JOHP on behalf
     of the Client in the accounts referred to in paragraph 16 of this
     Agreement.


            PART III - Risk Warnings and Risk Disclosure Statement

<PAGE>
 
                 Investments Denominated in Foreign Currencies

If a liability of the Client in one currency is to be matched by an asset in a
different currency, or if JOHP provides services under this Agreement relating
to an investment denominated in a foreign currency, a movement in exchange rates
may have an effect which may be either favourable or unfavourable on the
investment, which effect may be separate from the gain or loss otherwise
experienced on such investment.

                      Investments not readily realisable

Certain categories of investments comprised in the Portfolio may not be readily
realisable.  You should be aware that there can be no certainty that market
makers or brokers will be prepared to deal in such investments and that proper
information for determining their current value may not be available.

                                   Warrants

A warrant is a right to subscribe for shares, debentures, loan stock or
government securities, and is exercisable against the original issuer of the
securities.  Warrants often involve a high degree of gearing so that a
relatively small movement in the price of the underlying security results in a
disproportionately large movement, unfavourable as well as favourable, in the
price of the warrant.  The prices of warrants can therefore be volatile.

                                 Stabilisation

This statement is made in compliance with Rule 14 of Chapter IV of the rules of
IMRO.

"We or our representatives may from time to time effect on your behalf or
recommend to you transactions in securities which are the subject of a recent
new issue where the price of those transactions may have been influenced by bids
made or transactions effected for the purpose of stabilising the price of those
securities.  You should read the explanation below carefully.  Its purpose is to
enable you to judge whether you wish your funds to be invested at all in such
securities or, if so, whether you wish to authorise us generally to effect
transactions in such securities on your behalf without further reference to you
or whether you wish to be consulted before any particular transaction is
effected on your behalf.

Stabilisation is a process whereby the market price of a security is pegged or
fixed during the period in which a new issue of securities is sold to the
public.  Stabilisation may take place in the new issue or in other securities
related to the new issue in such a way that the price of the other securities
may affect the price of the new issue or vice versa.

The reason stabilisation is permitted is that when a new issue is brought to
market the sudden glut will sometimes force the price lower for a period of time
before buyers are found for the securities on offer.

As long as he obeys a strict set of rules the "stabilising manager", normally
the issuing house chiefly responsible for bringing a new issue to market, is
entitled to buy securities in the market that he has previously sold to
investors or allotted to institutions who were included in 

                                                           Page 140 of 258 Pages

<PAGE>
 
the new issue but who have decided not to continue participating. The effect of
this may be to keep the price at a higher level than would otherwise be the case
during the period of stabilising.

The rules limit the period in which he may stabilise, fix the price at which he
may stabilise (in the case of shares and warrants but not bonds), and require
him to disclose that he may be (but not that he is) stabilising.

The fact that a new issue or a related security is being stabilised does not in
itself mean that investors are not interested in the issue, but neither should
the existence of transactions in an issue where stabilising may take place be
relied upon as an indication that investors are interested in the new issue or
interested in purchasing at the price at which transactions are taking place".

NOW IT IS HEREBY AGREED as follows:

APPOINTMENT AND STATUS OF CLIENT

1.   The Client, a Private Customer as defined in the Rules of IMRO, hereby
     appoints JOHP to act as discretionary investment manager, subject to the
     terms and conditions hereof, in relation to the Client's investments and
     cash which are from time to time placed under the management of JOHP (the
     "Portfolio") and JOHP hereby agrees to manage and administer the Portfolio.
     The appointment will commence on the date on which this Agreement is
     delivered to JOHP by the Client having been signed first by the Client then
     by JOHP.  The assets comprising the Portfolio and their opening value are
     set out in Schedule 1.

MANAGEMENT OF INVESTMENTS

2.   JOHP shall have complete discretion, power and authority to manage the
     Portfolio and to make investments and changes in investments on the
     Client's behalf and as the Client's agent within the investment policy
     agreed between JOHP and the Client and set out in Part 1 of Schedule II.
     Such policy shall be subject to the guidelines and restrictions set out in
     Part II of Schedule II and to any guidelines, restrictions and instructions
     specified in writing from time to time by the Client or by the Client's
     duly authorized agent (written notice of whose authority shall have been
     received by JOHP).  The Client's attention is specifically drawn to the
     warnings set out in Part III of Schedule II.

                                                           Page 145 of 258 Pages
<PAGE>
 
3.   JOHP shall not be obliged to undertake the management of investments the
     management of which would in its opinion be onerous to it.

DEALING TERMS

4.   Subject as set out in paragraph 9, in effecting transactions for the
     Portfolio JOHP shall seek best execution at all times and may (subject to
     the investment policy set out in Part I of Schedule II) deal on such
     markets or exchanges and with such counterparties as it thinks fit.  The
     Client agrees that all such transactions will be effected in accordance
     with the rules and regulations of the relevant market or exchange and that
     JOHP may take all such steps as may be required or permitted by such rules
     and regulations and/or by good market practice.

5.   The Client's investments or documents of title or certificates evidencing
     title to investments or any other property belonging to the Client will not
     be lent by JOHP to a third party except as otherwise agreed between the
     Client and JOHP in writing.

6.   JOHP may supplement the funds in the Portfolio by borrowing on the Client's
     behalf but only for the purpose of funding short-term deficiencies arising
     in the normal course of JOHP's duties hereunder to an extent which is not
     material in the context of the Portfolio taken as a whole.  JOHP will not
     borrow money on the Client's behalf against the security of any of the
     Client's investments, documents of title or property.

7.   JOHP may commit the Client to underwrite any issue or offer for sale of
     securities without the Client's prior written consent.

8.   JOHP may act as principal in any transaction for the Client provided that
     JOHP shall secure for the Client best execution of such transaction.

9.   Subject to the IMRO Rules, JOHP may, without prior reference to the Client,
     enter into a transaction on behalf of more than one client collectively.

10.  JOHP has the right under this Agreement to effect transactions on the
     Client's behalf in investments the price of which may be being stabilized.
     The attention of the Client is referred to the statement contained in
     Schedule II relating to stabilization.  Signature of this Agreement by or
     on behalf of the Client shall act as acknowledgment by the Client of
     receipt of such statement prior to entry into this Agreement.

CONFLICTS OF INTEREST

11.  Subject to paragraphs 12 and 13, JOHP shall not undertake any transactions
     on the Client's behalf in which JOHP has directly or indirectly a material
     interest or have any relationship with another party which may involve a
     conflict with JOHP's duty to the Client unless that interest or
     relationship is disclosed in writing to the Client.

12.  The Client's Portfolio may contain securities of which the issue or offer
     for sale is underwritten, managed or arranged by an Associate (as defined
     in the Rules of IMRO) of JOHP during the preceding twelve months.

                                                           Page 146 of 258 Pages
<PAGE>
 
13.  The Client understands that JOHP's directors or staff may from time to time
     hold shares or securities including holdings that may be in the Portfolio,
     and that JOHP's directors or staff may from time to time be directors of
     companies whose shares are held in the Portfolio.

14.  The Client acknowledges that JOHP may acquire or dispose of on the Client's
     behalf shares or units in any fund, company, trust or Collective Investment
     Scheme (as defined by the Rules of IMRO) under JOHP's management (or in a
     fund, company, trust or Collective Investment Scheme connected with JOHP)
     if JOHP considers such an investment to be appropriate for inclusion in or
     exclusion from the Portfolio.

CUSTODIAL SERVICES

15.  (a)  Save where the Client has notified JOHP in accordance with paragraph
          15(b), in those  cases where the Client is situated in the United
          Kingdom registerable investments will be registered in the name of an
          Eligible Custodian (as defined in the Rules of IMRO) situated in the
          United Kingdom and nominated by JOHP.

     (b)  In those cases where the Client is situated overseas or where the
          Client so requests by notice in writing to JOHP, registerable
          investments will be registered in the name of an Eligible Custodian
          situated outside the United Kingdom and nominated by JOHP.

     (c)  All documents of title (including those in bearer form) will be
          retained in the custody of an Eligible Custodian nominated by JOHP and
          situated in the United Kingdom or overseas as applicable.

     (d)  None of the Eligible Custodians as aforesaid shall be Associates of
          JOHP.  However, the Client's registerable investments may at any time
          be registered in the name of a nominee company which is an Associate
          of JOHP and Client's documents of title may be held by that Associate
          at any time after JOHP shall have given the Client written notice of
          its intention to do so.  Such notice shall specify the nature of its
          association with such Associate.

ACCOUNTS, INTEREST AND DIVIDENDS

16.  The following Client accounts, together with such others that may be
     required, will be maintained by JOHP.

     (a)  INVESTMENT ACCOUNT

          The Client's investments will be held in this account.  Subject to
          paragraphs 5 and 6, JOHP shall not lend the Client's investments to
          any third party and shall not borrow money on the Client's behalf
          against the security of the Client's investments.

     (b)  CAPITAL ACCOUNT



                                                           Page 147 of 258 Pages
<PAGE>
 
          All uninvested cash will be held in this account by a bank chosen by
          JOHP.  The account will be debited with the cost of purchases on the
          Client's behalf and with sums due and payable by the Client to JOHP
          and will be credited with the net proceeds of sales on the Client's
          behalf.  Money drawn on behalf of the Client from the account shall
          not exceed the total of money held in the account on behalf of the
          Client at that time.  Interest will be paid on sums standing to the
          credit of the account and held on the Client's behalf at the
          prevailing market rate.  The interest will be paid quarterly and will
          be credited to the Income Account on the Client's behalf.

     (c)  SETTLEMENT ACCOUNT

          Money debited to the Capital Account in respect of the cost of
          purchases made on the Client's behalf and money received and
          receivable upon settlement of each sale made on the Client's behalf
          will be credited to this account and held there until the relevant
          settlement date.

     (d)  INCOME ACCOUNT

          Dividends and interest received on investments within the Portfolio
          will be credited to this account.  Balances on the account will be
          paid away quarterly in accordance with the Client's instructions or,
          in the absence of such instructions, will be transferred quarterly to
          the Capital Account as soon as reasonably practicable after the last
          day of each such quarter being 5th April, 30th June, 5th October and
          31st December in each year.  Money drawn on behalf of the Client from
          the account shall not exceed the total of money held in the account on
          behalf of the Client at that time.  Interest will not be paid on
          monies held in this account.

     (d)  OFF-SHORE FUNDS

          In those cases where the Client is situated overseas or if the Client
          notifies JOHP in writing that the Client wishes cash in the Portfolio
          to be held outside the United Kingdom, JOHP will be (subject to
          applicable laws and regulations) hold such cash in a bank account
          outside the United Kingdom

17.  The Client may at any time instruct JOHP to realise any or all of the
     investments in the Portfolio and may withdraw any sum standing to the
     credit of the Capital Account and held on the Client's behalf.

18.  JOHP shall maintain separate ledger accounts on the Client's behalf.  All
     debits from and credits to the Investment Account and/or Capital Account
     and/or Income Account on the Client's behalf shall be recorded in the
     ledger accounts, and statements of account showing all transactions,
     payments and receipts up to and including 5th April of each year will be
     sent to the Client as soon as reasonably practicable after that date.

<PAGE>
 
19.  In the interests of proper administration of the Portfolio and for related
     investment purposes JOHP, its representatives or employees, may call upon
     the Client by telephone, visit or otherwise communicate orally with the
     Client without express invitation.  The Client's attention is drawn to the
     fact that the Client will forfeit any right conferred by section 56 of the
     Financial Services Act 1986 to treat as unenforceable any investment
     agreement entered into in the course of or in consequence of such a call.

ADMINISTRATION

20.  Contract notes in respect of every purchase and sale on the Client's behalf
     will be sent to the Client before the close of business on the day next
     following the day on which the transaction was effected.

21.  JOHP will on the Client's request forward details of all transactions on
     the Client's behalf to the Client's tax advisor without additional charge.

22.  The Client may (upon giving reasonable notice) inspect all copy contract
     notes, vouchers and copies of entries in books or electronic recording
     media kept by JOHP or to which JOHP has access relating to the transactions
     effected by JOHP on the Client's behalf and those records will be
     maintained by JOHP or JOHP will ensure that they are maintained for not
     less than seven years from the date of the relevant transaction.

23.  All documents will be sent to the Client at the address given above unless
     and until otherwise directed in writing.  The Client agrees that it will
     immediately notify JOHP in writing of any changes of address, and that JOHP
     will not be responsible for any consequences which may arise from failure
     to do so.

REVIEWS AND VALUATIONS

24.  JOHP will prepare reviews of the Portfolio incorporating an up-to-date
     valuation of each investment comprised in the Portfolio and a statement of
     the basis on which it was valued on a six monthly basis or at such other
     frequency as may be agreed between JOHP and the Client.  Such reviews shall
     be prepared as at such half yearly or other dates as shall be agreed
     between JOHP and the Client from time to time (each such date being
     referred to as a "Valuation Date"), and JOHP will send such reviews to the
     Client within twenty-five business days of each Valuation Date.

25.  On each Valuation Date cash will be valued at its face value and each
     investment will be valued at its middle market price on the relevant stock
     exchange at the close of business on such day or (if not a business day) on
     the nearest prior business day as is supplied by "Exshare" or any other
     suitable information service chosen by JOHP (which figures shall be binding
     save for manifest error).  For the purpose of valuing in sterling any
     foreign currency or any security listed on a foreign stock exchange the
     price of which is quoted in currency other than sterling, the valuation and
     middle market exchange rates supplied by "Exshare" or any other suitable
     information service chosen by JOHP shall be applied.  In the absence of
     that valuation or exchange rate, the middle market price as determined by
     the Daily Official List of The Stock 

                                                           Page 149 of 258 Pages
<PAGE>
 
     Exchange or the equivalent list for any relevant stock exchange will be
     applied. If none of the foregoing methods of valuation are available, the
     investments in question will be valued in such other manner (by JOHP or
     such other person selected by JOHP) as shall in JOHP's opinion be fair.

26.  JOHP accepts no liability for any period longer than 25 business days
     between any Valuation Date and the despatch of a review to the Client of
     his Portfolio which has elapsed as a result of any act or omission of any
     third party.

VOTING AND OTHER RIGHTS

27.  JOHP will be entitled at its discretion and without notice to the Client to
     procure or to refrain from procuring the exercise of voting and other
     rights and privileges attaching to the investments comprised in the
     Portfolio and to accede or refrain from acceding to any compromise or
     arrangement in relation to any scheme of arrangement or scheme for
     reconstruction or amalgamation involving any such investment.  JOHP will
     not forward to the Client any circulars, notices or proxy cards received in
     respect of investments comprised in the Portfolio.

FEES, COMMISSIONS AND EXPENSES

28.  (a)  The Client will pay a management fee to JOHP in respect of the period
          beginning with first receipt by JOHP of any investments or money from
          the Client and ending with a Valuation Date (as defined in paragraph
          24) and each period thereafter starting with the day after any
          Valuation Date and ending on the next Valuation Date (or the
          Termination Date as defined in paragraph 39 if sooner).

     (b)  The management fee shall be calculated in accordance with the 'Scale
          Rates and Charges' set out in Schedule III.

     (c)  The management fee shall be payable not later than 14 days after
          despatch to the Client of an invoice which shall be sent to the Client
          as soon as is reasonably practicable after each Valuation Date.
          Unless otherwise instructed the Client's Capital Account will be
          debited with the amounts due to JOHP on the 14th day after despatch of
          such invoice.

     (d)  In addition the Client shall reimburse JOHP for any expenses or
          liabilities which it may incur in properly carrying out its duties
          hereunder.

29.  The management fee shall be deemed to have accrued on a day-to-day basis,
     so that, if this Agreement commences or terminates other than on a
     Valuation Date (as defined in paragraph 24), the amount of the fee shall be
     duly apportioned.

30.  Commissions (as set out in Schedule III) will be payable by the Client on
     purchases and sales of investments together with all expenses including
     stamp duties, stamp duty reserve tax and VAT thereon (if applicable).  The
     Client recognises that JOHP may gain a commission benefit from dealing in a
     bulk purchase or sale on behalf of JOHP's

     clients, one of whom may be the Client, or from return commissions which
     benefit JOHP shall be entitled to retain. JOHP will be free to accept and
     retain as an addition to its fees and commissions any other commissions
     which it receives in the course of its dealing on the Client's behalf: all
     such benefits and receipts shall supplement any other remuneration
     receivable by JOHP in connection with transactions effected by JOHP with or
     for the Client under this or any other agreement with the Client and the
     Client consents to all such benefits and receipts as are referred to above
     without prior disclosure of the same to the Client on a case-by-case basis
     provided that JOHP undertakes to secure for the Client best execution of
     all transactions effected with or through a party from whom JOHP receives
     such benefits and commissions, disregarding any benefit which the Client
     might obtain directly or indirectly as a result of such arrangements.

31.  JOHP shall be entitled to alter the manner of computing or charging its
     fees, commissions and expenses or of paying interest on the money held on
     the Client's behalf in the Capital Account (including with prejudice to the
     generality of the foregoing its scale rates and charges) by giving one
     month's prior notice in writing to the Client.

RESPONSIBILITY AND INSURANCE

32.  JOHP will indemnify the Client in respect of any loss incurred as a result
     of negligence, wilful default or fraud by JOHP or any of its employees.
     Subject to the above, JOHP will not be responsible or liable for any claim,
     loss, damage, expense or costs arising by reason of any of the following:

     (a)  any investment decision taken and acted upon in accordance with the
          terms of this Agreement; or

     (b)  any delay or default in the performance of its obligations under this
          Agreement arising in consequence of any event or circumstance beyond
          the reasonable control of JOHP; or

     (c)  any act or omission on the part of any of the banks or nominee
          companies controlled by them or other eligible custodians as referred
          to in paragraph 15 or any other person to which any of them shall have
          delegated its function or on the part of any other third party
          whatsoever; or

     (d)  any consequential loss suffered in consequence of any act or omission
          of JOHP or any breach of JOHP of any term of this Agreement.

33.  The Client agrees to indemnify and keep indemnified JOHP from and against
     all demands, claims, liabilities, losses, damages, costs and expenses
     whatsoever incurred by JOHP arising out of the breach by the Client of any
     warranty or by reason of any failure by the Client to comply with and/or
     perform any of the terms and conditions contained in this Agreement.

<PAGE>
 
34.  Where the Client is a joint account (whether or not a trust account) JOHP
     shall unless and until otherwise directed in writing by all the persons
     named in the joint account, be entitled to act on the instructions of any
     of them and shall not in any whatsoever be liable to the others for doing
     so.

35.  JOHP has effected insurance to provide for the protection of the Client
     against losses arising from any negligence of JOHP or any dishonesty of
     employees of JOHP.

36.  Under Section 54 of the Financial Services Act 1986 The Securities and
     Investments Board has established a scheme for compensating investors by
     which the Client may be entitled to compensation in the event of JOHP's
     inability to meet any liabilities to the Client.  JOHP will make available
     to the Client upon request a statement describing the Client's rights to
     compensation under the scheme.

DELEGATION AND USE OF AGENTS

37.  JOHP may delegate any of its functions under this Agreement to an Associate
     and may provide information about the Client and the Portfolio to any such
     Associate but JOHP's liability to the Client for all matters so delegated
     shall not be affected thereby.  JOHP shall give to the Client written
     notice of any delegation of a function which involves the exercise of its
     discretionary investment management powers.

38.  JOHP may employ agents (including Associates) to perform any
     administrative, dealing, custodial and ancillary services required to
     enable JOHP to perform its services under this Agreement.  JOHP undertakes
     to act in good faith and with due diligence in the choice and use of such
     agents.

TERMINATION OF AGREEMENT

39.  This Agreement may be terminated by either party by giving written notice
     of termination to the other at any time.  Termination shall take effect on
     the day upon which the other party actually receives the notice (the
     "Termination Date") provided that, where the Client is a joint account,
     notice of termination by JOHP shall be given to every person named in the
     joint account and in such circumstances the Termination Date shall be
     deemed to be the day after the date of posting by first class recorded
     delivery or other appropriate means to all persons named in the joint
     account.

40.  Upon the Termination Date, JOHP will complete expeditiously all
     transactions in progress at termination but will not execute any further
     transactions for the Client.  Upon all fees, commissions, expenses and
     other sums due to it and any other liabilities for which it may be or
     become liable in connection with the management of the Portfolio being
     settled or adequately secured to the satisfaction of JOHP, JOHP will ensure
     that all investments and cash balances held on the Client's behalf will,
     after any outstanding security registration, stock exchange settlements and
     other administrative matters have been completed and as soon as reasonably
     practicable, be transferred to the Client or dealt with in accordance with
     the Client's instructions, in all cases at the cost of the Client.

<PAGE>
 
41.  Termination will not affect accrued rights, existing commitments or any
     contractual provision intended to survive termination and will be without
     penalty or other additional payment except that JOHP may charge the Client
     an amount equal to:

     (a)  the relevant proportion of the management fee, corresponding to that
          part of the period ending on a Valuation Date by reference to which
          fees are payable, which has expired when this Agreement is terminated;

     (b)  any additional expenses which JOHP necessarily incurs in terminating
          this Agreement; and

     (c)  any losses necessarily realised in settling or concluding outstanding
          obligations.

42.  The death, bankruptcy or other incapacity or, in the case of a body
     corporate, the cessation of business of the Client or a petition being
     presented or a meeting being convened to consider a resolution for the
     liquidation of the Client shall not of itself terminate JOHP's appointment;
     but JOHP may at its discretion treat its receipt of actual notice of any
     such events as if it were a written notice of termination from the Client.

43.  If the Client is a joint account the Client's obligations under this
     Agreement shall be joint and several.  On the death of any of the persons
     constituting the Client (being survived by any such other person), the
     Agreement shall not terminate and, except in the case of trustees, the
     interest of the deceased in the Portfolio shall automatically enure to the
     benefit of the survivor(s) unless otherwise specified by notice in writing
     to JOHP.

CLIENT WARRANTIES

44.  The Client warrants that the Client is the beneficial owner (or the duly
     authorised agent of the beneficial owner) of the whole of the Portfolio
     free from all liens, charges, encumbrances and restrictions on transfer
     except insofar as advised by the Client to JOHP, and will so remain during
     the currency of this Agreement.

45.  The Client warrants that the Client is empowered to enter into this
     Agreement without the consent or authority of any other party and in the
     case of a Client being a body corporate the Client warrants that by
     entering into this Agreement it is not nor will it be in breach of its
     Memorandum or Articles of Association or any other relevant document.

GENERAL

46.  Terms and expressions defined in the rules of IMRO for the time being in
     force shall where the context so admits bear the same meaning in this
     Agreement.

47.  The Clause headings in this Agreement are included for ease of reference
     only and shall not affect its interpretation.

48.  The Schedules to this Agreement are an integral part of it.

     served by the Client from within the United Kingdom and of notice served
     upon the Client at an address within the United Kingdom the notice shall be

     Investment Manager who was not involved in the circumstances relating to
     the complaint and who will investigate such circumstances.  Upon the
     conclusion of his investigation he shall make a written report to the
     Client and take any action he deems necessary to rectify the matter which
     is the subject of the complaint.  The Client has the right to refer any
     complaint to IMRO if the Client is not satisfied with the action taken by
     the Chief Executive or Senior Investment Manager, and in any event has the
     right to make the complaint direct to IMRO or the Investment Ombudsman

                                   SCHEDULE I

                                 THE PORTFOLIO

                     Valuation and composition of Portfolio
           (see attached letter/opening valuation - where applicable)


                                  SCHEDULE II

                 INVESTMENT POLICY, GUIDELINES AND RESTRICTIONS

                   PART I - Investment Policy including basis
                         of measurement of performance

The investment objectives are to maintain a maximum total return commensurate
with safety and the protection of the underlying value of the capital of the
fund.



The performance will be measured against the F.T. All Share Index, any other
appropriate Index or measure of performance agreed upon by JOHP and the Client.


                     PART II - Guidelines and Restrictions

1.   There will be no restrictions placed on the types of investment in which
     the money comprised in the Portfolio will be invested provided that the
     services to be provided by JOHP will not include advising on or effecting
     Contingent Liability Transactions, nor will they, without the express prior
     authority of the Client, relate to options, futures or contracts for
     differences (or to any right or interest in such investments).


2.   The contents of the Portfolio may be invested in any market save for the
     following.


     There shall be no restriction on the amount of monies or proportion of the
     Portfolio invested in any one investment or type of investment permitted
     hereunder provided that, subject to the provisions relating to overdraft
     contained in paragraph 6 of this Agreement, under no circumstances will
     JOHP make investments on behalf of the Client to a value in excess of the
     aggregate of the value of the funds and securities held by JOHP on behalf
     of the Client in the accounts referred to in paragraph 16 of this
     Agreement.


            PART III - Risk Warnings and Risk Disclosure Statement



                                                           Page 155 of 258 Pages
<PAGE>
 
                 Investments Denominated in Foreign Currencies

If a liability of the Client in one currency is to be matched by an asset in a
different currency, or if JOHP provides services under this Agreement relating
to an investment denominated in a foreign currency, a movement in exchange rates
may have an effect which may be either favourable or unfavourable on the
investment, which effect may be separate from the gain or loss otherwise
experienced on such investment.

                      Investments not readily realisable

Certain categories of investments comprised in the Portfolio may not be readily
realisable.  You should be aware that there can be no certainty that market
makers or brokers will be prepared to deal in such investments and that proper
information for determining their current value may not be available.

                                   Warrants

A warrant is a right to subscribe for shares, debentures, loan stock or
government securities, and is exercisable against the original issuer of the
securities.  Warrants often involve a high degree of gearing so that a
relatively small movement in the price of the underlying security results in a
disproportionately large movement, unfavourable as well as favourable, in the
price of the warrant.  The prices of warrants can therefore be volatile.

                                 Stabilisation

This statement is made in compliance with Rule 14 of Chapter IV of the rules of
IMRO.

"We or our representatives may from time to time effect on your behalf or
recommend to you transactions in securities which are the subject of a recent
new issue where the price of those transactions may have been influenced by bids
made or transactions effected for the purpose of stabilising the price of those
securities.  You should read the explanation below carefully.  Its purpose is to
enable you to judge whether you wish your funds to be invested at all in such
securities or, if so, whether you wish to authorise us generally to effect
transactions in such securities on your behalf without further reference to you
or whether you wish to be consulted before any particular transaction is
effected on your behalf.

Stabilisation is a process whereby the market price of a security is pegged or
fixed during the period in which a new issue of securities is sold to the
public.  Stabilisation may take place in the new issue or in other securities
related to the new issue in such a way that the price of the other securities
may affect the price of the new issue or vice versa.

The reason stabilisation is permitted is that when a new issue is brought to
market the sudden glut will sometimes force the price lower for a period of time
before buyers are found for the securities on offer.

As long as he obeys a strict set of rules the "stabilising manager", normally
the issuing house chiefly responsible for bringing a new issue to market, is
entitled to buy securities in the market that he has previously sold to
investors or allotted to institutions who were included in 

                                                           Page 156 of 258 Pages
<PAGE>
 
the new issue but who have decided not to continue participating. The effect of
this may be to keep the price at a higher level than would otherwise be the case
during the period of stabilising.

The rules limit the period in which he may stabilise, fix the price at which he
may stabilise (in the case of shares and warrants but not bonds), and require
him to disclose that he may be (but not that he is) stabilising.

The fact that a new issue or a related security is being stabilised does not in
itself mean that investors are not interested in the issue, but neither should
the existence of transactions in an issue where stabilising may take place be
relied upon as an indication that investors are interested in the new issue or
interested in purchasing at the price at which transactions are taking place".

            Regulated by IMRO in the conduct of Investment Business
                         DISCRETIONARY CLIENT AGREEMENT
THIS INVESTMENT MANAGEMENT AGREEMENT is made the 25th day of February 1998
BETWEEN:
(1)  JO HAMBRO CAPITAL MANAGEMENT LIMITED ("JOHCMP") a member of the Investment
     Management Regulatory Organization Limited ("IMRO") and regulated in the
     conduct of investment business by it, whose registered office is at 10 Park
     Place, London SW1A 1LP; and
(2)  City of Joy Ltd.            (portfolio name)
     (hereafter known as the "Client")
     of Merrill Lynch Bank and Trust Company (Cayman) Ltd.
     P.O. Box 1164 British American Building, Phase III, 5th Floor, Dr. Roy's
     Drive, George Town, Grand Cayman, British West Indies            (address)

NOW IT IS HEREBY AGREED as follows:

APPOINTMENT AND STATUS OF CLIENT

1.   The Client, a Private Customer as defined in the Rules of IMRO, hereby
     appoints JOHCM to act as discretionary investment manager, subject to the
     terms and conditions hereof, in relation to the Client's investments and
     cash which are from time to time placed under the management of JOHCM (the
     "Portfolio") and JOHCM hereby agrees to manage and administer the
     Portfolio.  The appointment will commence on the date on which this
     Agreement is delivered to JOHCM by the Client having been signed first by
     the Client then by JOHCM.  The assets comprising the Portfolio and their
     opening value are set out in Schedule 1.

MANAGEMENT OF INVESTMENTS

2.   JOHCM shall have complete discretion, power and authority to manage the
     Portfolio and to make investments and changes in investments on the
     Client's behalf and as the Client's agent within the investment policy
     agreed between JOHCM and the Client and set out in Part 1 of Schedule II.
     Such policy shall be subject to the guidelines and restrictions set out in
     Part II of Schedule II and to any guidelines, restrictions and instructions
     specified in writing from time to time by the Client or by the Client's
     duly authorized agent (written notice of whose authority shall have been
     received by 

                                                           Page 161 of 258 Pages
<PAGE>
 
     JOHCM).  The Client's attention is specifically drawn to the
     warnings set out in Part III of Schedule II.

3.   JOHCM shall not be obliged to undertake the management of investments the
     management of which would in its opinion be onerous to it.

DEALING TERMS

4.   Subject as set out in paragraph 9, in effecting transactions for the
     Portfolio JOHCM shall seek best execution at all times and may (subject to
     the investment policy set out in Part I of Schedule II) deal on such
     markets or exchanges and with such counterparties as it thinks fit.  The
     Client agrees that all such transactions will be effected in accordance
     with the rules and regulations of the relevant market or exchange and that
     JOHCM may take all such steps as may be required or permitted by such rules
     and regulations and/or by good market practice.

5.   The Client's investments or documents of title or certificates evidencing
     title to investments or any other property belonging to the Client will not
     be lent by JOHCM to a third party except as otherwise agreed between the
     Client and JOHCM in writing.

6.   JOHCM may supplement the funds in the Portfolio by borrowing on the
     Client's behalf but only for the purpose of funding short-term deficiencies
     arising in the normal course of JOHCM's duties hereunder to an extent which
     is not material in the context of the Portfolio taken as a whole.  JOHCM
     will not borrow money on the Client's behalf against the security of any of
     the Client's investments, documents of title or property.

7.   JOHCM may commit the Client to underwrite any issue or offer for sale of
     securities without the Client's prior written consent.

8.   JOHCM may act as principal in any transaction for the Client provided that
     JOHCM shall secure for the Client best execution of such transaction.

9.   Subject to the IMRO Rules, JOHCM may, without prior reference to the
     Client, enter into a transaction on behalf of more than one client
     collectively.

10.  JOHCM has the right under this Agreement to effect transactions on the
     Client's behalf in investments the price of which may be being stabilized.
     The attention of the Client is referred to the statement contained in
     Schedule II relating to stabilization.  Signature of this Agreement by or
     on behalf of the Client shall act as acknowledgment by the Client of
     receipt of such statement prior to entry into this Agreement.

CONFLICTS OF INTEREST

     on the Client's behalf in which JOHCM has directly or indirectly a material
     interest or have any relationship with another party which may involve a
     conflict with JOHCM's duty to the Client unless that interest or
     relationship is disclosed in writing to the Client.

12.  The Client's Portfolio may contain securities of which the issue or offer
     for sale is underwritten, managed or arranged by an Associate (as defined
     in the Rules of IMRO) of JOHCM during the preceding twelve months.

13.  The Client understands that JOHCM's directors or staff may from time to
     time hold shares or securities including holdings that may be in the
     Portfolio, and that JOHCM's directors or staff may from time to time be
     directors of companies whose shares are held in the Portfolio.

14.  The Client acknowledges that JOHCM may acquire or dispose of on the
     Client's behalf shares or units in any fund, company, trust or Collective
     Investment Scheme (as defined by the Rules of IMRO) under JOHCM's
     management (or in a fund, company, trust or Collective Investment Scheme
     connected with JOHCM) if JOHCM considers such an investment to be
     appropriate for inclusion in or exclusion from the Portfolio.

CUSTODIAL SERVICES

15.  (a)  Save where the Client has notified JOHCM in accordance with paragraph
          15(b), in those  cases where the Client is situated in the United
          Kingdom registerable investments will be registered in the name of an
          Eligible Custodian (as defined in the Rules of IMRO) situated in the
          United Kingdom and nominated by JOHCM.

     (b)  In those cases where the Client is situated overseas or where the
          Client so requests by notice in writing to JOHCM, registerable
          investments will be registered in the name of an Eligible Custodian
          situated outside the United Kingdom and nominated by JOHCM.

     (c)  All documents of title (including those in bearer form) will be
          retained in the custody of an Eligible Custodian nominated by JOHCM
          and situated in the United Kingdom or overseas as applicable.

     (d)  None of the Eligible Custodians as aforesaid shall be Associates of
          JOHCM. However, the Client's registerable investments may at any time
          be registered in the name of a nominee company which is an Associate
          of JOHCM and Client's documents of title may be held by that Associate
          at any time after JOHCM shall have given the Client written notice of
          its intention to do so.  Such notice shall specify the nature of its
          association with such Associate.

ACCOUNTS, INTEREST AND DIVIDENDS

16.  The following Client accounts, together with such others that may be
     required, will be maintained by JOHCM.

     (a)  INVESTMENT ACCOUNT

          The Client's investments will be held in this account.  Subject to
          paragraphs 5 and 6, JOHCM shall not lend the Client's investments to

                                                           Page 163 of 258 Pages

          Client's investments.

     (b)  CAPITAL ACCOUNT

          All uninvested cash will be held in this account by a bank chosen by
          JOHCM. The account will be debited with the cost of purchases on the
          Client's behalf and with sums due and payable by the Client to JOHCM
          and will be credited with the net proceeds of sales on the Client's
          behalf.  Money drawn on behalf of the Client from the account shall
          not exceed the total of money held in the account on behalf of the
          Client at that time.  Interest will be paid on sums standing to the
          credit of the account and held on the Client's behalf at the
          prevailing market rate.  The interest will be paid quarterly and will
          be credited to the Income Account on the Client's behalf.

     (c)  SETTLEMENT ACCOUNT

          Money debited to the Capital Account in respect of the cost of
          purchases made on the Client's behalf and money received and

          will be credited to this account and held there until the relevant
          settlement date.

     (d)  INCOME ACCOUNT

          Dividends and interest received on investments within the Portfolio
          will be credited to this account.  Balances on the account will be
          paid away quarterly in accordance with the Client's instructions or,
          in the absence of such instructions, will be transferred quarterly to
          the Capital Account as soon as reasonably practicable after the last
          day of each such quarter being 5th April, 30th June, 5th October and
          31st December in each year.  Money drawn on behalf of the Client from
          the account shall not exceed the total of money held in the account on
          behalf of the Client at that time.  Interest will not be paid on
          monies held in this account.

     (d)  OFF-SHORE FUNDS

          In those cases where the Client is situated overseas or if the Client
          notifies JOHCM in writing that the Client wishes cash in the Portfolio
          to be held outside the United Kingdom, JOHCM will be (subject to
          applicable laws and regulations) hold such cash in a bank account
          outside the United Kingdom

17.  The Client may at any time instruct JOHCM to realise any or all of the
     investments in the Portfolio and may withdraw any sum standing to the
     credit of the Capital Account and held on the Client's behalf.

18.  JOHCM shall maintain separate ledger accounts on the Client's behalf.  All
     debits from and credits to the Investment Account and/or Capital Account
     and/or Income Account on the Client's behalf shall be recorded in the
     ledger accounts, and statements of 

                                                           Page 164 of 258 Pages
<PAGE>
 
     account showing all transactions, payments and receipts up to and including
     5th April of each year will be sent to the Client as soon as reasonably
     practicable after that date.

COMMUNICATIONS

19.  In the interests of proper administration of the Portfolio and for related
     investment purposes JOHCM, its representatives or employees, may call upon
     the Client by telephone, visit or otherwise communicate orally with the
     Client without express invitation.  The Client's attention is drawn to the
     fact that the Client will forfeit any right conferred by section 56 of the
     Financial Services Act 1986 to treat as unenforceable any investment
     agreement entered into in the course of or in consequence of such a call.

ADMINISTRATION

20.  Contract notes in respect of every purchase and sale on the Client's behalf
     will be sent to the Client before the close of business on the day next
     following the day on which the transaction was effected.

21.  JOHCM will on the Client's request forward details of all transactions on
     the Client's behalf to the Client's tax advisor without additional charge.

22.  The Client may (upon giving reasonable notice) inspect all copy contract
     notes, vouchers and copies of entries in books or electronic recording
     media kept by JOHCM or to which JOHCM has access relating to the
     transactions effected by JOHCM on the Client's behalf and those records
     will be maintained by JOHCM or JOHCM will ensure that they are maintained
     for not less than seven years from the date of the relevant transaction.

23.  All documents will be sent to the Client at the address given above unless
     and until otherwise directed in writing.  The Client agrees that it will
     immediately notify JOHCM in writing of any changes of address, and that
     JOHCM will not be responsible for any consequences which may arise from
     failure to do so.

REVIEWS AND VALUATIONS

24.  JOHCM will prepare reviews of the Portfolio incorporating an up-to-date
     valuation of each investment comprised in the Portfolio and a statement of
     the basis on which it was valued on a six monthly basis or at such other
     frequency as may be agreed between JOHCM and the Client.  Such reviews
     shall be prepared as at such half yearly or other dates as shall be agreed
     between JOHCM and the Client from time to time (each such date being
     referred to as a "Valuation Date"), and JOHCM will send such reviews to the
     Client within twenty-five business days of each Valuation Date.

25.  On each Valuation Date cash will be valued at its face value and each
     investment will be valued at its middle market price on the relevant stock
     exchange at the close of business on such day or (if not a business day) on
     the nearest prior business day as is supplied by "Exshare" or any other
     suitable information service chosen by JOHCM 

                                                           Page 165 of 258 Pages
<PAGE>
 
     (which figures shall be binding save for manifest error). For the purpose
     of valuing in sterling any foreign currency or any security listed on a
     foreign stock exchange the price of which is quoted in currency other than
     sterling, the valuation and middle market exchange rates supplied by
     "Exshare" or any other suitable information service chosen by JOHCM shall
     be applied. In the absence of that valuation or exchange rate, the middle
     market price as determined by the Daily Official List of The Stock Exchange
     or the equivalent list for any relevant stock exchange will be applied. If
     none of the foregoing methods of valuation are available, the investments
     in question will be valued in such other manner (by JOHCM or such other
     person selected by JOHCM) as shall in JOHCM's opinion be fair.

26.  JOHCM accepts no liability for any period longer than 25 business days
     between any Valuation Date and the despatch of a review to the Client of
     his Portfolio which has elapsed as a result of any act or omission of any
     third party.

VOTING AND OTHER RIGHTS

27.  JOHCM will be entitled at its discretion and without notice to the Client
     to procure or to refrain from procuring the exercise of voting and other
     rights and privileges attaching to the investments comprised in the
     Portfolio and to accede or refrain from acceding to any compromise or
     arrangement in relation to any scheme of arrangement or scheme for
     reconstruction or amalgamation involving any such investment.  JOHCM will
     not forward to the Client any circulars, notices or proxy cards received in
     respect of investments comprised in the Portfolio.

FEES, COMMISSIONS AND EXPENSES

28.  (a)  The Client will pay a management fee to JOHCM in respect of the period
          beginning with first receipt by JOHCM of any investments or money from
          the Client and ending with a Valuation Date (as defined in paragraph
          24) and each period thereafter starting with the day after any
          Valuation Date and ending on the next Valuation Date (or the
          Termination Date as defined in paragraph 39 if sooner).

     (b)  The management fee shall be calculated in accordance with the 'Scale
          Rates and Charges' set out in Schedule III.

     (c)  The management fee shall be payable not later than 14 days after
          despatch to the Client of an invoice which shall be sent to the Client
          as soon as is reasonably practicable after each Valuation Date.
          Unless otherwise instructed the Client's Capital Account will be
          debited with the amounts due to JOHCM on the 14th day after despatch
          of such invoice.

     (d)  In addition the Client shall reimburse JOHCM for any expenses or
          liabilities which it may incur in properly carrying out its duties
          hereunder.

                                                          Pages 166 of 258 Pages
<PAGE>
 
29.  The management fee shall be deemed to have accrued on a day-to-day basis,
     so that, if this Agreement commences or terminates other than on a
     Valuation Date (as defined in paragraph 24), the amount of the fee shall be
     duly apportioned.

30.  Commissions (as set out in Schedule III) will be payable by the Client on
     purchases and sales of investments together with all expenses including
     stamp duties, stamp duty reserve tax and VAT thereon (if applicable). The
     Client recognises that JOHCM may gain a commission benefit from dealing in
     a bulk purchase or sale on behalf of JOHCM's clients, one of whom may be
     the Client, or from return commissions which benefit JOHCM shall be
     entitled to retain. JOHCM will be free to accept and retain as an addition
     to its fees and commissions any other commissions which it receives in the
     course of its dealing on the Client's behalf: all such benefits and
     receipts shall supplement any other remuneration receivable by JOHCM in
     connection with transactions effected by JOHCM with or for the Client under
     this or any other agreement with the Client and the Client consents to all
     such benefits and receipts as are referred to above without prior
     disclosure of the same to the Client on a case-by-case basis provided that
     JOHCM undertakes to secure for the Client best execution of all
     transactions effected with or through a party from whom JOHCM receives such
     benefits and commissions, disregarding any benefit which the Client might
     obtain directly or indirectly as a result of such arrangements.

31.  JOHCM shall be entitled to alter the manner of computing or charging its
     fees, commissions and expenses or of paying interest on the money held on
     the Client's behalf in the Capital Account (including with prejudice to the
     generality of the foregoing its scale rates and charges) by giving one
     month's prior notice in writing to the Client.


RESPONSIBILITY AND INSURANCE

32.  JOHCM will indemnify the Client in respect of any loss incurred as a result
     of negligence, wilful default or fraud by JOHCM or any of its employees.
     Subject to the above, JOHCM will not be responsible or liable for any
     claim, loss, damage, expense or costs arising by reason of any of the
     following:

     (a)  any investment decision taken and acted upon in accordance with the
          terms of this Agreement; or

     (b)  any delay or default in the performance of its obligations under this
          Agreement arising in consequence of any event or circumstance beyond
          the reasonable control of JOHCM; or

     (c)  any act or omission on the part of any of the banks or nominee
          companies controlled by them or other eligible custodians as referred
          to in paragraph 15 or any other person to which any of them shall have
          delegated its function or on the part of any other third party
          whatsoever; or

     (d)  any consequential loss suffered in consequence of any act or omission
          of JOHCM or any breach of JOHCM of any term of this Agreement.

<PAGE>
 
33.  The Client agrees to indemnify and keep indemnified JOHCM from and against
     all demands, claims, liabilities, losses, damages, costs and expenses
     whatsoever incurred by JOHCM arising out of the breach by the Client of any
     warranty or by reason of any failure by the Client to comply with and/or
     perform any of the terms and conditions contained in this Agreement.

34.  Where the Client is a joint account (whether or not a trust account) JOHCM
     shall unless and until otherwise directed in writing by all the persons
     named in the joint account, be entitled to act on the instructions of any
     of them and shall not in any whatsoever be liable to the others for doing
     so.

35.  JOHCM has effected insurance to provide for the protection of the Client
     against losses arising from any negligence of JOHCM or any dishonesty of
     employees of JOHCM.

36.  Under Section 54 of the Financial Services Act 1986 The Securities and
     Investments Board has established a scheme for compensating investors by
     which the Client may be entitled to compensation in the event of JOHCM's
     inability to meet any liabilities to the Client. JOHCM will make available
     to the Client upon request a statement describing the Client's rights to
     compensation under the scheme.


DELEGATION AND USE OF AGENTS

37.  JOHCM may delegate any of its functions under this Agreement to an
     Associate and may provide information about the Client and the Portfolio to
     any such Associate but JOHCM's liability to the Client for all matters so
     delegated shall not be affected thereby. JOHCM shall give to the Client
     written notice of any delegation of a function which involves the exercise
     of its discretionary investment management powers.

38.  JOHCM may employ agents (including Associates) to perform any
     administrative, dealing, custodial and ancillary services required to
     enable JOHCM to perform its services under this Agreement. JOHCM undertakes
     to act in good faith and with due diligence in the choice and use of such
     agents.


TERMINATION OF AGREEMENT

39.  This Agreement may be terminated by either party by giving written notice
     of termination to the other at any time. Termination shall take effect on
     the day upon which the other party actually receives the notice (the
     "Termination Date") provided that, where the Client is a joint account,
     notice of termination by JOHCM shall be given to every person named in the
     joint account and in such circumstances the Termination Date shall be
     deemed to be the day after the date of posting by first class recorded
     delivery or other appropriate means to all persons named in the joint
     account.

40.  Upon the Termination Date, JOHCM will complete expeditiously all
     transactions in progress at termination but will not execute any further
     transactions for the Client. Upon all fees, commissions, expenses and other
     sums due to it and any other liabilities for which it may be or become
     liable in connection with the management of the Portfolio being settled or
     adequately secured to the satisfaction of JOHCM, JOHCM


                                                           Page 168 of 258 Pages

<PAGE>
 
     will ensure that all investments and cash balances held on the Client's
     behalf will, after any outstanding security registration, stock exchange
     settlements and other administrative matters have been completed and as
     soon as reasonably practicable, be transferred to the Client or dealt with
     in accordance with the Client's instructions, in all cases at the cost of
     the Client.

41.  Termination will not affect accrued rights, existing commitments or any
     contractual provision intended to survive termination and will be without
     penalty or other additional payment except that JOHCM may charge the Client
     an amount equal to:

     (a)  the relevant proportion of the management fee, corresponding to that
          part of the period ending on a Valuation Date by reference to which
          fees are payable, which has expired when this Agreement is terminated;

     (b)  any additional expenses which JOHCM necessarily incurs in terminating
          this Agreement; and

     (c)  any losses necessarily realised in settling or concluding outstanding
          obligations.

42.  The death, bankruptcy or other incapacity or, in the case of a body
     corporate, the cessation of business of the Client or a petition being
     presented or a meeting being convened to consider a resolution for the
     liquidation of the Client shall not of itself terminate JOHCM's
     appointment; but JOHCM may at its discretion treat its receipt of actual
     notice of any such events as if it were a written notice of termination
     from the Client.

43.  If the Client is a joint account the Client's obligations under this
     Agreement shall be joint and several. On the death of any of the persons
     constituting the Client (being survived by any such other person), the
     Agreement shall not terminate and, except in the case of trustees, the
     interest of the deceased in the Portfolio shall automatically enure to the
     benefit of the survivor(s) unless otherwise specified by notice in writing
     to JOHCM.


CLIENT WARRANTIES

44.  The Client warrants that the Client is the beneficial owner (or the duly
     authorised agent of the beneficial owner) of the whole of the Portfolio
     free from all liens, charges, encumbrances and restrictions on transfer
     except insofar as advised by the Client to JOHCM, and will so remain during
     the currency of this Agreement.

45.  The Client warrants that the Client is empowered to enter into this
     Agreement without the consent or authority of any other party and in the
     case of a Client being a body corporate the Client warrants that by
     entering into this Agreement it is not nor will it be in breach of its
     Memorandum or Articles of Association or any other relevant document.

          (see attached letter/opening valuation - where applicable)


                                  SCHEDULE II

      PART I - Investment Policy, Benchmarks, Guidelines and Restrictions

Investment Policy, Benchmarks, Guidelines and Restrictions are to be recorded on
the accompanying Investment Strategy Schedule which forms a part of the Client
Questionnaire. JOHCM may from time to time require this form to be updated in
order that the Client's requirements are accurately recorded.

                     Soft Commission Disclosure Statement


                 Investments Denominated in Foreign Currencies

If a liability of the Client in one currency is to be matched by an asset in a
different currency, or if JOHCM provides services under this Agreement relating
to an investment denominated in a foreign currency, a movement in exchange rates
may have an effect which may be either favourable or unfavourable on the
investment, which effect may be separate from the gain or loss otherwise
experienced on such investment.


                       Investments not readily realisable

Certain categories of investments comprised in the Portfolio may not be readily
realisable. You should be aware that there can be no certainty that market
makers or brokers will be prepared to deal in such investments and that proper
information for determining their current value may not be available.


                                    Warrants

A warrant is a right to subscribe for shares, debentures, loan stock or
government securities, and is exercisable against the original issuer of the
securities. Warrants often involve a high degree of gearing so that a relatively
small movement in the price of the underlying security results in a
disproportionately large movement, unfavourable as well as favourable, in the
price of the warrant. The prices of warrants can therefore be volatile.


                                 Stabilisation

This statement is made in compliance with Rule 14 of Chapter IV of the rules of
IMRO.

"We or our representatives may from time to time effect on your behalf or
recommend to you transactions in securities which are the subject of a recent
new issue where the price of those transactions may have been influenced by bids
made or transactions effected for the purpose of stabilising the price of those
securities. You should read the explanation below carefully. Its purpose is to
enable you to judge whether you wish your funds to be invested at all in such
securities or, if so, whether you wish to authorise us generally to effect
transactions in such securities on your behalf without further reference to you
or whether you wish to be consulted before any particular transaction is
effected on your behalf.

Stabilisation is a process whereby the market price of a security is pegged or
fixed during the period in which a new issue of securities is sold to the
public. Stabilisation may take place in the new issue or in other securities
related to the new issue in such a way that the price of the other securities
may affect the price of the new issue or vice versa.

The reason stabilisation is permitted is that when a new issue is brought to
market the sudden glut will sometimes force the price lower for a period of time
before buyers are found for the securities on offer.

As long as he obeys a strict set of rules the "stabilising manager", normally
the issuing house chiefly responsible for bringing a new issue to market, is
entitled to buy securities in the market that he has previously sold to
investors or allotted to institutions who were included in the new issue but who
have decided not to continue participating. The effect of this may be to keep
the price at a higher level than would otherwise be the case during the period
of stabilising.

The rules limit the period in which he may stabilise, fix the price at which he
may stabilise (in the case of shares and warrants but not bonds), and require
him to disclose that he may be (but not that he is) stabilising.

The fact that a new issue or a related security is being stabilised does not in
itself mean that investors are not interested in the issue, but neither should
the existence of transactions in an issue where stabilising may take place be
relied upon as an indication that investors are interested in the new issue or
interested in purchasing at the price at which transactions are taking place".


                                Soft Commission

JOHCM has entered into agreements with each of Southcoast Capital Corporation
and Wheat First Butcher Singer (US brokers), whereby they have agreed to pay the
costs of JOHCM's on-line Reuters and First Call computerised analysis services.
These arrangements are known as soft commission agreements.

It is JOHCM's policy to enter into soft commission agreements where it believes
that such arrangements will benefit its clients. The existence of these soft
commission agreements does not deflect from JOHCM's obligation to provide best
execution in respect of any transaction JOHCM executes on behalf of it Clients.

Any uninvested cash in the Client's Portfolio not invested in US Treasury Bills
will be held in designated client bank accounts with Bank of Scotland (Isle of
Man) Ltd. The Bank of Scotland (Isle of Man) Ltd. has acknowledged in writing
that (i) all money held to the credit of such accounts is held by JOHCM as
trustee, and that it is not entitled to combine the accounts with any other
account or to exercise any right of set-off or counterclaim against money in
those accounts in respect of any sum owed on any of JOHCM's other accounts, (ii)
that interest earned on these accounts shall be accredited to such accounts or
to accounts of that type, and (iii) that the title of these accounts
sufficiently distinguishes those accounts from any accounts containing money
belonging to JOHCM, and are in the form requested by JOHCM.

By signing and returning this contract the Client agrees that it is happy for
its uninvested cash to be held in accounts with the Bank of Scotland (Isle of
Man) Ltd. on the terms set out in this agreement.

BETWEEN:

(1)  JO HAMBRO CAPITAL MANAGEMENT LIMITED ("JOHCMP") a member of the Investment

NOW IT IS HEREBY AGREED as follows:

APPOINTMENT AND STATUS OF CLIENT

1.   The Client, a Private Customer as defined in the Rules of IMRO, hereby
     appoints JOHCM to act as discretionary investment manager, subject to the
     terms and conditions hereof, in relation to the Client's investments and
     cash which are from time to time placed under the management of JOHCM (the
     "Portfolio") and JOHCM hereby agrees to manage and administer the
     Portfolio.  The appointment will commence on the date on which this
     Agreement is delivered to JOHCM by the Client having been signed first by
     the Client then by JOHCM.  The assets comprising the Portfolio and their
     opening value are set out in Schedule 1.

MANAGEMENT OF INVESTMENTS

2.   JOHCM shall have complete discretion, power and authority to manage the
     Portfolio and to make investments and changes in investments on the
     Client's behalf and as the Client's agent within the investment policy
     agreed between JOHCM and the Client and set out in Part 1 of Schedule II.
     Such policy shall be subject to the guidelines and restrictions set out in
     Part II of Schedule II and to any guidelines, restrictions and instructions
     specified in writing from time to time by the Client or by the Client's
     duly authorized agent (written notice of whose authority shall have been
     received by JOHCM).  The Client's attention is specifically drawn to the
     warnings set out in Part III of Schedule II.

<PAGE>
 
3.   JOHCM shall not be obliged to undertake the management of investments the
     management of which would in its opinion be onerous to it.

DEALING TERMS

4.   Subject as set out in paragraph 9, in effecting transactions for the
     Portfolio JOHCM shall seek best execution at all times and may (subject to
     the investment policy set out in Part I of Schedule II) deal on such
     markets or exchanges and with such counterparties as it thinks fit.  The
     Client agrees that all such transactions will be effected in accordance
     with the rules and regulations of the relevant market or exchange and that
     JOHCM may take all such steps as may be required or permitted by such rules
     and regulations and/or by good market practice.

5.   The Client's investments or documents of title or certificates evidencing
     title to investments or any other property belonging to the Client will not
     be lent by JOHCM to a third party except as otherwise agreed between the
     Client and JOHCM in writing.

6.   JOHCM may supplement the funds in the Portfolio by borrowing on the
     Client's behalf but only for the purpose of funding short-term deficiencies
     arising in the normal course of JOHCM's duties hereunder to an extent which
     is not material in the context of the Portfolio taken as a whole.  JOHCM
     will not borrow money on the Client's behalf against the security of any of
     the Client's investments, documents of title or property.

7.   JOHCM may commit the Client to underwrite any issue or offer for sale of
     securities without the Client's prior written consent.

8.   JOHCM may act as principal in any transaction for the Client provided that
     JOHCM shall secure for the Client best execution of such transaction.

9.   Subject to the IMRO Rules, JOHCM may, without prior reference to the
     Client, enter into a transaction on behalf of more than one client
     collectively.

10.  JOHCM has the right under this Agreement to effect transactions on the
     Client's behalf in investments the price of which may be being stabilized.
     The attention of the Client is referred to the statement contained in
     Schedule II relating to stabilization.  Signature of this Agreement by or
     on behalf of the Client shall act as acknowledgment by the Client of
     receipt of such statement prior to entry into this Agreement.

CONFLICTS OF INTEREST

11.  Subject to paragraphs 12 and 13, JOHCM shall not undertake any transactions
     on the Client's behalf in which JOHCM has directly or indirectly a material
     interest or have any relationship with another party which may involve a
     conflict with JOHCM's duty to the Client unless that interest or
     relationship is disclosed in writing to the Client.

<PAGE>
 
12.  The Client's Portfolio may contain securities of which the issue or offer
     for sale is underwritten, managed or arranged by an Associate (as defined
     in the Rules of IMRO) of JOHCM during the preceding twelve months.

13.  The Client understands that JOHCM's directors or staff may from time to
     time hold shares or securities including holdings that may be in the
     Portfolio, and that JOHCM's directors or staff may from time to time be
     directors of companies whose shares are held in the Portfolio.

14.  The Client acknowledges that JOHCM may acquire or dispose of on the
     Client's behalf shares or units in any fund, company, trust or Collective
     Investment Scheme (as defined by the Rules of IMRO) under JOHCM's
     management (or in a fund, company, trust or Collective Investment Scheme
     connected with JOHCM) if JOHCM considers such an investment to be
     appropriate for inclusion in or exclusion from the Portfolio.

CUSTODIAL SERVICES

15.  (a)  Save where the Client has notified JOHCM in accordance with paragraph
          15(b), in those cases where the Client is situated in the United
          Kingdom registerable investments will be registered in the name of an
          Eligible Custodian (as defined in the Rules of IMRO) situated in the
          United Kingdom and nominated by JOHCM.

     (b)  In those cases where the Client is situated overseas or where the
          Client so requests by notice in writing to JOHCM, registerable
          investments will be registered in the name of an Eligible Custodian
          situated outside the United Kingdom and nominated by JOHCM.

     (c)  All documents of title (including those in bearer form) will be
          retained in the custody of an Eligible Custodian nominated by JOHCM
          and situated in the United Kingdom or overseas as applicable.

     (d)  None of the Eligible Custodians as aforesaid shall be Associates of
          JOHCM. However, the Client's registerable investments may at any time
          be registered in the name of a nominee company which is an Associate
          of JOHCM and Client's documents of title may be held by that Associate
          at any time after JOHCM shall have given the Client written notice of
          its intention to do so.  Such notice shall specify the nature of its
          association with such Associate.

ACCOUNTS, INTEREST AND DIVIDENDS

16.  The following Client accounts, together with such others that may be
     required, will be maintained by JOHCM.

     (a)  INVESTMENT ACCOUNT

          The Client's investments will be held in this account.  Subject to
          paragraphs 5 and 6, JOHCM shall not lend the Client's investments to
          any third party and

                                                           Page 179 of 258 Pages
<PAGE>
 
          shall not borrow money on the Client's behalf against the security of
          the Client's investments.

     (b)  CAPITAL ACCOUNT

          All uninvested cash will be held in this account by a bank chosen by
          JOHCM. The account will be debited with the cost of purchases on the
          Client's behalf and with sums due and payable by the Client to JOHCM
          and will be credited with the net proceeds of sales on the Client's
          behalf.  Money drawn on behalf of the Client from the account shall
          not exceed the total of money held in the account on behalf of the
          Client at that time.  Interest will be paid on sums standing to the
          credit of the account and held on the Client's behalf at the
          prevailing market rate.  The interest will be paid quarterly and will
          be credited to the Income Account on the Client's behalf.

     (c)  SETTLEMENT ACCOUNT

          Money debited to the Capital Account in respect of the cost of
          purchases made on the Client's behalf and money received and
          receivable upon settlement of each sale made on the Client's behalf
          will be credited to this account and held there until the relevant
          settlement date.

     (d)  INCOME ACCOUNT

          Dividends and interest received on investments within the Portfolio
          will be credited to this account.  Balances on the account will be
          paid away quarterly in accordance with the Client's instructions or,
          in the absence of such instructions, will be transferred quarterly to
          the Capital Account as soon as reasonably practicable after the last
          day of each such quarter being 5th April, 30th June, 5th October and
          31st December in each year.  Money drawn on behalf of the Client from
          the account shall not exceed the total of money held in the account on
          behalf of the Client at that time.  Interest will not be paid on
          monies held in this account.

     (d)  OFF-SHORE FUNDS

          In those cases where the Client is situated overseas or if the Client
          notifies JOHCM in writing that the Client wishes cash in the Portfolio
          to be held outside the United Kingdom, JOHCM will be (subject to
          applicable laws and regulations) hold such cash in a bank account
          outside the United Kingdom.

17.  The Client may at any time instruct JOHCM to realise any or all of the
     investments in the Portfolio and may withdraw any sum standing to the
     credit of the Capital Account and held on the Client's behalf.

18.  JOHCM shall maintain separate ledger accounts on the Client's behalf.  All
     debits from and credits to the Investment Account and/or Capital Account
     and/or Income Account on the Client's behalf shall be recorded in the
     ledger accounts, and statements of 

                                                           Page 180 of 258 Pages
<PAGE>
 
     account showing all transactions, payments and receipts up to and including
     5th April of each year will be sent to the Client as soon as reasonably
     practicable after that date.

COMMUNICATIONS

19.  In the interests of proper administration of the Portfolio and for related
     investment purposes JOHCM, its representatives or employees, may call upon
     the Client by telephone, visit or otherwise communicate orally with the
     Client without express invitation.  The Client's attention is drawn to the
     fact that the Client will forfeit any right conferred by section 56 of the
     Financial Services Act 1986 to treat as unenforceable any investment
     agreement entered into in the course of or in consequence of such a call.

ADMINISTRATION

20.  Contract notes in respect of every purchase and sale on the Client's behalf
     will be sent to the Client before the close of business on the day next
     following the day on which the transaction was effected.

21.  JOHCM will on the Client's request forward details of all transactions on
     the Client's behalf to the Client's tax advisor without additional charge.

22.  The Client may (upon giving reasonable notice) inspect all copy contract
     notes, vouchers and copies of entries in books or electronic recording
     media kept by JOHCM or to which JOHCM has access relating to the
     transactions effected by JOHCM on the Client's behalf and those records
     will be maintained by JOHCM or JOHCM will ensure that they are maintained
     for not less than seven years from the date of the relevant transaction.

23.  All documents will be sent to the Client at the address given above unless
     and until otherwise directed in writing.  The Client agrees that it will
     immediately notify JOHCM in writing of any changes of address, and that
     JOHCM will not be responsible for any consequences which may arise from
     failure to do so.

REVIEWS AND VALUATIONS

24.  JOHCM will prepare reviews of the Portfolio incorporating an up-to-date
     valuation of each investment comprised in the Portfolio and a statement of
     the basis on which it was valued on a six monthly basis or at such other
     frequency as may be agreed between JOHCM and the Client.  Such reviews
     shall be prepared as at such half yearly or other dates as shall be agreed
     between JOHCM and the Client from time to time (each such date being
     referred to as a "Valuation Date"), and JOHCM will send such reviews to the
     Client within twenty-five business days of each Valuation Date.

25.  On each Valuation Date cash will be valued at its face value and each
     investment will be valued at its middle market price on the relevant stock
     exchange at the close of business on such day or (if not a business day) on
     the nearest prior business day as is supplied by "Exshare" or any other
     suitable information service chosen by JOHCM 

                                                           Page 181 of 258 Pages
<PAGE>
 
     (which figures shall be binding save for manifest error). For the purpose
     of valuing in sterling any foreign currency or any security listed on a
     foreign stock exchange the price of which is quoted in currency other than
     sterling, the valuation and middle market exchange rates supplied by
     "Exshare" or any other suitable information service chosen by JOHCM shall
     be applied. In the absence of that valuation or exchange rate, the middle
     market price as determined by the Daily Official List of The Stock Exchange
     or the equivalent list for any relevant stock exchange will be applied. If
     none of the foregoing methods of valuation are available, the investments
     in question will be valued in such other manner (by JOHCM or such other
     person selected by JOHCM) as shall in JOHCM's opinion be fair.

26.  JOHCM accepts no liability for any period longer than 25 business days
     between any Valuation Date and the despatch of a review to the Client of
     his Portfolio which has elapsed as a result of any act or omission of any
     third party.

VOTING AND OTHER RIGHTS

27.  JOHCM will be entitled at its discretion and without notice to the Client
     to procure or to refrain from procuring the exercise of voting and other
     rights and privileges attaching to the investments comprised in the
     Portfolio and to accede or refrain from acceding to any compromise or
     arrangement in relation to any scheme of arrangement or scheme for
     reconstruction or amalgamation involving any such investment.  JOHCM will
     not forward to the Client any circulars, notices or proxy cards received in
     respect of investments comprised in the Portfolio.

FEES, COMMISSIONS AND EXPENSES

28.  (a)  The Client will pay a management fee to JOHCM in respect of the period
          beginning with first receipt by JOHCM of any investments or money from
          the Client and ending with a Valuation Date (as defined in paragraph
          24) and each period thereafter starting with the day after any
          Valuation Date and ending on the next Valuation Date (or the
          Termination Date as defined in paragraph 39 if sooner).

     (b)  The management fee shall be calculated in accordance with the 'Scale
          Rates and Charges' set out in Schedule III.

     (c)  The management fee shall be payable not later than 14 days after
          despatch to the Client of an invoice which shall be sent to the Client
          as soon as is reasonably practicable after each Valuation Date.
          Unless otherwise instructed the Client's Capital Account will be
          debited with the amounts due to JOHCM on the 14th day after despatch
          of such invoice.

     (d)  In addition the Client shall reimburse JOHCM for any expenses or
          liabilities which it may incur in properly carrying out its duties
          hereunder.

29.  The management fee shall be deemed to have accrued on a day-to-day basis,
     so that, if this Agreement commences or terminates other than on a
     Valuation Date (as defined in paragraph 24), the amount of the fee shall be
     duly apportioned.

30.  Commissions (as set out in Schedule III) will be payable by the Client on
     purchases and sales of investments together with all expenses including
     stamp duties, stamp duty reserve tax and VAT thereon (if applicable).  The
     Client recognises that JOHCM may gain a commission benefit from dealing in
     a bulk purchase or sale on behalf of JOHCM's clients, one of whom may be
     the Client, or from return commissions which benefit JOHCM shall be
     entitled to retain.  JOHCM will be free to accept and retain as an addition
     to its fees and commissions any other commissions which it receives in the
     course of its dealing on the Client's behalf:  all such benefits and
     receipts shall supplement any other remuneration receivable by JOHCM in
     connection with transactions effected by JOHCM with or for the Client under
     this or any other agreement with the Client and the Client consents to all
     such benefits and receipts as are referred to above without prior
     disclosure of the same to the Client on a case-by-case basis provided that
     JOHCM undertakes to secure for the Client best execution of all
     transactions effected with or through a party from whom JOHCM receives such
     benefits and commissions, disregarding any benefit which the Client might
     obtain directly or indirectly as a result of such arrangements.

31.  JOHCM shall be entitled to alter the manner of computing or charging its
     fees, commissions and expenses or of paying interest on the money held on
     the Client's behalf in the Capital Account (including with prejudice to the
     generality of the foregoing its scale rates and charges) by giving one
     month's prior notice in writing to the Client.

RESPONSIBILITY AND INSURANCE

32.  JOHCM will indemnify the Client in respect of any loss incurred as a result
     of negligence, wilful default or fraud by JOHCM or any of its employees.
     Subject to the above, JOHCM will not be responsible or liable for any
     claim, loss, damage, expense or costs arising by reason of any of the
     following:

     (a) any investment decision taken and acted upon in accordance with the
         terms of this Agreement; or

     (b)  any delay or default in the performance of its obligations under this
          Agreement arising in consequence of any event or circumstance beyond
          the reasonable control of JOHCM; or

     (c)  any act or omission on the part of any of the banks or nominee
          companies controlled by them or other eligible custodians as referred
          to in paragraph 15 or any other person to which any of them shall have
          delegated its function or on the part of any other third party
          whatsoever; or

     (d)  any consequential loss suffered in consequence of any act or omission
          of JOHCM or any breach of JOHCM of any term of this Agreement.

<PAGE>
 
33.  The Client agrees to indemnify and keep indemnified JOHCM from and against
     all demands, claims, liabilities, losses, damages, costs and expenses
     whatsoever incurred by JOHCM arising out of the breach by the Client of any
     warranty or by reason of any failure by the Client to comply with and/or
     perform any of the terms and conditions contained in this Agreement.

34.  Where the Client is a joint account (whether or not a trust account) JOHCM
     shall unless and until otherwise directed in writing by all the persons
     named in the joint account, be entitled to act on the instructions of any
     of them and shall not in any whatsoever be liable to the others for doing
     so.

35.  JOHCM has effected insurance to provide for the protection of the Client
     against losses arising from any negligence of JOHCM or any dishonesty of
     employees of JOHCM.

36.  Under Section 54 of the Financial Services Act 1986 The Securities and
     Investments Board has established a scheme for compensating investors by
     which the Client may be entitled to compensation in the event of JOHCM's
     inability to meet any liabilities to the Client.  JOHCM will make available
     to the Client upon request a statement describing the Client's rights to
     compensation under the scheme.

DELEGATION AND USE OF AGENTS

37.  JOHCM may delegate any of its functions under this Agreement to an
     Associate and may provide information about the Client and the Portfolio to
     any such Associate but JOHCM's liability to the Client for all matters so
     delegated shall not be affected thereby.  JOHCM shall give to the Client
     written notice of any delegation of a function which involves the exercise
     of its discretionary investment management powers.

38.  JOHCM may employ agents (including Associates) to perform any
     administrative, dealing, custodial and ancillary services required to
     enable JOHCM to perform its services under this Agreement.  JOHCM
     undertakes to act in good faith and with due diligence in the choice and
     use of such agents.

TERMINATION OF AGREEMENT

39.  This Agreement may be terminated by either party by giving written notice
     of termination to the other at any time.  Termination shall take effect on
     the day upon which the other party actually receives the notice (the
     "Termination Date") provided that, where the Client is a joint account,
     notice of termination by JOHCM shall be given to every person named in the
     joint account and in such circumstances the Termination Date shall be
     deemed to be the day after the date of posting by first class recorded
     delivery or other appropriate means to all persons named in the joint
     account.

40.  Upon the Termination Date, JOHCM will complete expeditiously all
     transactions in progress at termination but will not execute any further
     transactions for the Client. Upon all fees, commissions, expenses and other
     sums due to it and any other liabilities for which it may be or become
     liable in connection with the management of the Portfolio being settled or
     adequately secured to the satisfaction of JOHCM, JOHCM 

                                                           Page 184 of 258 Pages
<PAGE>
 
     will ensure that all investments and cash balances held on the Client's
     behalf will, after any outstanding security registration, stock exchange
     settlements and other administrative matters have been completed and as
     soon as reasonably practicable, be transferred to the Client or dealt with
     in accordance with the Client's instructions, in all cases at the cost of
     the Client.

41.  Termination will not affect accrued rights, existing commitments or any
     contractual provision intended to survive termination and will be without
     penalty or other additional payment except that JOHCM may charge the Client
     an amount equal to:

     (a)  the relevant proportion of the management fee, corresponding to that
          part of the period ending on a Valuation Date by reference to which
          fees are payable, which has expired when this Agreement is terminated;

     (b)  any additional expenses which JOHCM necessarily incurs in terminating
          this Agreement; and

     (c)  any losses necessarily realised in settling or concluding outstanding
          obligations.

42.  The death, bankruptcy or other incapacity or, in the case of a body
     corporate, the cessation of business of the Client or a petition being
     presented or a meeting being convened to consider a resolution for the
     liquidation of the Client shall not of itself terminate JOHCM's
     appointment; but JOHCM may at its discretion treat its receipt of actual
     notice of any such events as if it were a written notice of termination
     from the Client.

43.  If the Client is a joint account the Client's obligations under this
     Agreement shall be joint and several.  On the death of any of the persons
     constituting the Client (being survived by any such other person), the
     Agreement shall not terminate and, except in the case of trustees, the
     interest of the deceased in the Portfolio shall automatically enure to the
     benefit of the survivor(s) unless otherwise specified by notice in writing
     to JOHCM.

CLIENT WARRANTIES

44.  The Client warrants that the Client is the beneficial owner (or the duly
     authorised agent of the beneficial owner) of the whole of the Portfolio
     free from all liens, charges, encumbrances and restrictions on transfer
     except insofar as advised by the Client to JOHCM, and will so remain during
     the currency of this Agreement.

45.  The Client warrants that the Client is empowered to enter into this
     Agreement without the consent or authority of any other party and in the
     case of a Client being a body corporate the Client warrants that by
     entering into this Agreement it is not nor will it be in breach of its
     Memorandum or Articles of Association or any other relevant document.

     the complaint and who will investigate such circumstances.  Upon the
     conclusion of his investigation he shall make a written report to the
     Client and take any action he deems necessary to rectify the matter which
     is the subject of the complaint.  The Client has the right to refer any

                                 THE PORTFOLIO

                     Valuation and composition of Portfolio
           (see attached letter/opening valuation - where applicable)


                                  SCHEDULE II

      PART I - Investment Policy, Benchmarks, Guidelines and Restrictions

Investment Policy, Benchmarks, Guidelines and Restrictions are to be recorded on
the accompanying Investment Strategy Schedule which forms a part of the Client
Questionnaire. JOHCM may from time to time require this form to be updated in
order that the Client's requirements are accurately recorded.


             PART II - Risk Warnings, Risk Disclosure Statement and
                      Soft Commission Disclosure Statement


                 Investments Denominated in Foreign Currencies

If a liability of the Client in one currency is to be matched by an asset in a
different currency, or if JOHCM provides services under this Agreement relating
to an investment denominated in a foreign currency, a movement in exchange rates
may have an effect which may be either favourable or unfavourable on the
investment, which effect may be separate from the gain or loss otherwise
experienced on such investment.


                       Investments not readily realisable

Certain categories of investments comprised in the Portfolio may not be readily
realisable. You should be aware that there can be no certainty that market
makers or brokers will be prepared to deal in such investments and that proper
information for determining their current value may not be available.


                                    Warrants

A warrant is a right to subscribe for shares, debentures, loan stock or
government securities, and is exercisable against the original issuer of the
securities.  Warrants often involve a high degree of gearing so that a
relatively small movement in the price of the underlying security results in a
disproportionately large movement, unfavourable as well as favourable, in the
price of the warrant.  The prices of warrants can therefore be volatile.


                                 Stabilisation

This statement is made in compliance with Rule 14 of Chapter IV of the rules of
IMRO.

                                                           Page 187 of 258 Pages

"We or our representatives may from time to time effect on your behalf or
recommend to you transactions in securities which are the subject of a recent
new issue where the price of those transactions may have been influenced by bids
made or transactions effected for the purpose of stabilising the price of those
securities.  You should read the explanation below carefully.  Its purpose is to
enable you to judge whether you wish your funds to be invested at all in such
securities or, if so, whether you wish to authorise us generally to effect
transactions in such securities on your behalf without further reference to you
or whether you wish to be consulted before any particular transaction is
effected on your behalf.

Stabilisation is a process whereby the market price of a security is pegged or
fixed during the period in which a new issue of securities is sold to the
public.  Stabilisation may take place in the new issue or in other securities
related to the new issue in such a way that the price of the other securities
may affect the price of the new issue or vice versa.

The reason stabilisation is permitted is that when a new issue is brought to
market the sudden glut will sometimes force the price lower for a period of time
before buyers are found for the securities on offer.

As long as he obeys a strict set of rules the "stabilising manager", normally
the issuing house chiefly responsible for bringing a new issue to market, is
entitled to buy securities in the market that he has previously sold to
investors or allotted to institutions who were included in the new issue but who
have decided not to continue participating.  The effect of this may be to keep
the price at a higher level than would otherwise be the case during the period
of stabilising.

The rules limit the period in which he may stabilise, fix the price at which he
may stabilise (in the case of shares and warrants but not bonds), and require
him to disclose that he may be (but not that he is) stabilising.

The fact that a new issue or a related security is being stabilised does not in
itself mean that investors are not interested in the issue, but neither should
the existence of transactions in an issue where stabilising may take place be
relied upon as an indication that investors are interested in the new issue or
interested in purchasing at the price at which transactions are taking place".


                                Soft Commission

JOHCM has entered into agreements with each of Southcoast Capital Corporation
and Wheat First Butcher Singer (US brokers), whereby they have agreed to pay the
costs of JOHCM's on-line Reuters and First Call computerised analysis services.
These arrangements are known as soft commission agreements.

It is JOHCM's policy to enter into soft commission agreements where it believes
that such arrangements will benefit its clients.  The existence of these soft
commission agreements does not deflect from JOHCM's obligation to provide best
execution in respect of any transaction JOHCM executes on behalf of it Clients.

Any uninvested cash in the Client's Portfolio not invested in US Treasury Bills
will be held in designated client bank accounts with Bank of Scotland (Isle of
Man) Ltd.  The Bank of Scotland (Isle of Man) Ltd. has acknowledged in writing
that (i) all money held to the credit of such accounts is held by JOHCM as
trustee, and that it is not entitled to combine the accounts with any other
account or to exercise any right of set-off or counterclaim against money in
those accounts in respect of any sum owed on any of JOHCM's other accounts, (ii)
that interest earned on these accounts shall be accredited to such accounts or
to accounts of that type, and (iii) that the title of these accounts
sufficiently distinguishes those accounts from any accounts containing money
belonging to JOHCM, and are in the form requested by JOHCM.

By signing and returning this contract the Client agrees that it is happy for
its uninvested cash to be held in accounts with the Bank of Scotland (Isle of
Man) Ltd. on the terms set out in this agreement.

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

     THIS INVESTMENT MANAGEMENT AGREEMENT is made BETWEEN,

(1)  J O HAMBRO INVESTMENT MANAGEMENT LIMITED ("JOHIM") a member of the
     Investment Management Regulatory Organization Limited ("IMRO") whose
     registered office is at 30 Queen Anne's Gate London SW1H 9AL; and

(2)  R.C. Bonsor Will Trust (the "Client") of c/o Morley and Scott, Lynton
     House, 7-12 Tanstock Square, London WCIH 9LT

WHEREBY IT IS AGREED as follows:

56.  APPOINTMENT

The Client hereby appoints JOHIM to act as investment manager, subject to the
terms and conditions hereof in relation to the Client's investment and cash
which are from time to time placed under the management of JOHIM (the
"Portfolio") and JOHIM hereby agrees to manage and administer the Portfolio and
to render advice to the Client from time to time in connection with the
Portfolio. The Portfolio as at the date of this Agreement is comprised of the
investments and cash as set out and valued in Schedule I.

57.  AUTHORIZED BUSINESS

The business which JOHIM is authorized by IMRO to conduct is the giving of
investment advice in relation to, and the management of, the portfolios of
private and business customers and the arranging of transactions relating to
investments of any kind for all types of customers.

58.  MANAGEMENT OF INVESTMENTS

     (a) JOHIM shall, subject to paragraph 3.2, have complete discretion power
         and authority to manage the Portfolio and to make investments and
         changes in investments on the Client's behalf and as the Client's agent
         within the investment policy agreed between JOHIM and the Client and
         set out in Part I of Schedule II. Such policy shall be subject to the
         guidelines and restrictions set out in Part II of Schedule II and to
         any guidelines, restrictions and instructions specified in writing by
         the Client or by the Client's duly authorized agent (written notice of
         whose authority shall have been received by JOHIM). The Client's
         attention is specifically drawn to the warning set out in Part III of
         Schedule II.

     (b) JOHIM may, at its discretion, by telephone or by letter and upon either
         JOHIM's or the Client's instigation give advice and receive and act
         upon instructions given by the Client from time to time, upon the
         investment policy relating to the Portfolio and in relation to specific
         investments whether or not comprised in the Portfolio, which advice the
         client shall not be obliged to follow. JOHIM may refuse to carry out
         any such instructions which appear to it

                                                           Page 193 of 258 Pages
<PAGE>
 
     to be unreasonable or the carrying out of which would, in JOHIM's opinion,
     adversely affect the Portfolio, JOHIM may, but shall not be obliged to,
     inform the Client of the basis on which the judgment leading to such advice

     correspondents or agents or, if in bearer form will be held by the Bank,
     its correspondents or agents for the account of JOHIM clients.  Documents
     of title will be retained in the custody of the Bank, its correspondents or

          JOHIM's management (or in a fund, company, trust or Collective
          Investment Scheme connected with JOHIM) if JOHIM considers such an
          investment to be appropriate for inclusion in the Portfolio.

     (l)  The Client may (upon giving reasonable notice) inspect all copy
          contract notes, vouchers and copies of entries in books or electronic
          recording media kept by JOHIM or to which JOHIM has access relating to

     (b)  JOHIM shall not effect any transactions on behalf of the Client in
          securities, of which the issue or offer for sale was to JOHIM's

          ii.  Capital Account

               Client's behalf and with sums due and payable by the Client to
               JOHIM and will be credited with the net proceeds of sales on the
               Client's behalf. Money drawn on behalf of the Client from the
               account shall not exceed the total of money held in the account
               on behalf of the Client at that time. Interest will be paid on
               sums standing to the credit of the account and held on the

               behalf will be credited to this account and held there until the
               relevant settlement date.


          iv.  Income Account

               Dividends and interest received on investments within the
               Portfolio will be credited to this account. Balances on the
               account will be paid away quarterly in accordance with the
               Client's instructions or, in the absence of such instructions,
               will be transferred quarterly to the Capital Account on 5th
               April, 30th June, 30th September and 31st December in each year.
               Money drawn on behalf of the Client from the account shall not
               exceed the total money held in the account on behalf of the
               Client at that time. Interest will not be paid on monies held in
               this account.


          v.   Off-Shore Funds

               If the Client notifies JOHIM in writing that the Client wishes
               the investments and cash in the Portfolio to be held outside the
               United Kingdom, JOHIM may hold such investments and cash in a
               bank account outside the United Kingdom.

     (b)  The Client may at any time instruct JOHIM to realize any or all of the
          investments in the Portfolio and may withdraw any sum standing to the
          credit of the Capital Account and held on the Client's behalf.


                                                           Page 196 of 258 Pages

<PAGE>
 
     (c)  JOHIM shall maintain separate ledger accounts on the Client's behalf.
          All debits from and credits to the Investment Account and/or Capital
          Account and/or Income Account on the Client's behalf shall be recorded
          in the ledger accounts, and statements of account showing all
          transactions, payments and receipts up to and including 5th April of
          each year will be sent to the Client as soon as reasonably practicable
          after that date.


61.  FEES, COMMISSIONS AND EXPENSES

     (a)  The Client will pay to JOHIM from the date hereof a management fee in
          arrears on the lst May and lst November of each year in respect of the
          period of six months or any lesser period ending on the day prior to
          such date, and on the Termination Date (as defined in Clause 9.1) in
          respect of the period ending on that date, all in accordance with the
          'Scale Rates and Charges' set out in Schedule III. In addition the
          Client shall reimburse JOHIM for any expenses or liabilities which it
          may incur in property carrying out its duties hereunder.

     (b)  The management fee shall accrue on a day-to-day basis, so that, if
          this Agreement commences or terminates other than on lst May or lst
          November, the amount of the fee shall be duly apportioned.

     (c)  Commissions (as set out in Schedule III) will be payable by the Client
          on purchases and sales of investments, together with all expenses
          including stamp duties, stamp duty reserve tax and VAT thereon (if
          applicable). The Client recognizes that JOHIM may gain a commission
          benefit from dealing in a bulk purchase or sale on behalf of JOHIM's
          clients, one of whom may be the Client, or from return commissions,
          which benefit JOHIM shall be entitled to retain. JOHIM will be free to
          accept and retain as an addition to its fees and commissions any other
          commissions which it receives in the course of its dealing on the
          Client's behalf, all such benefits and receipts shall supplement any
          other remuneration receivable by JOHIM in connection with transactions
          effected by JOHIM with or for the Client under this or any other
          agreement with the Client and the Client consents to all such benefits
          and receipts as are referred to above without prior disclosure of the
          same to the Client on a case-by-case basis provided that JOHIM
          undertakes to secure for the Client best execution of all transactions
          effected with or through a party from which JOHIM receives such
          benefits and commissions, disregarding any benefit which might enure
          directly or indirectly to the Client as a result of such arrangements.

     (d)  JOHIM shall be entitled to alter the manner of computing or charging
          its fees, commissions and expenses or of paying interest on the money
          held on the Client's behalf in the Capital Account on the Client's
          behalf (including, without prejudice to the generality of the
          foregoing, its scale rates and charges) by giving one month's prior
          notice in writing to the Client.

     (e)  All sums due and payable by the Client to JOHIM will be transferred as
          soon as practicable from the money held on the Client's behalf in the
          Capital Account


                                                           Page 197 of 258 Pages

<PAGE>
 
          (and corresponding entire shall be made in the relevant ledger account
          maintained on the Client's behalf).

62.  REVIEWS AND VALUATIONS

     (a)  JOHIM will send to the Client on each Valuation Date (being in each
          year such half-yearly dates as are agreed between JOHIM and the Client
          from time to time) a review of the Portfolio incorporating an up-to-
          date valuation of each investment comprised in the Portfolio and a
          statement indicating how it was values.

     (b)  On each Valuation Date cash will be valued at its face value and each
          investment will be valued at its price on the relevant stock exchange
          at the close of business on such day or (if not a business day) on the
          nearest prior business day as is supplied by "Exshare" (which figures
          shall be biding save for manifest error). For the purpose of valuing
          in sterling any foreign currency or any security listed on a foreign
          stock exchange the price of which is quoted in currency other than
          sterling, the valuation and exchange rates supplied by "Exshare" shall
          be applied. In the absence of that valuation or exchange rate, the
          middle market price as determined by the Daily Official List of The
          Stock Exchange, London or the equivalent list for any relevant stock
          exchange will be applied. If none of the foregoing methods of
          valuation are available, the investments in question will be valued in
          such other manner (by JOHIM or such other person selected by JOHIM) as
          shall in JOHIM's opinion be fair.

     (c)  Each valuation will be made no more than 25 business days before the
          day on which the review incorporating it is sent to the Client
          provided that JOHIM accepts no liability for any longer period which
          may elapse as a result only of any act or omission of any third party.

63.  VOTING AND OTHER RIGHTS

     (a)  JOHIM will be entitled at its discretion and without notice to the
          Client to exercise or to refrain from exercising voting and other
          rights and privileges attaching to the investments comprised in the
          Portfolio and to accede or refrain from acceding to any compromise or
          arrangement in relation to any scheme of arrangement or schedule for
          reconstruction or amalgamation involving any such investment. JOHIM
          will not forward to the Client any circulars, notices or proxy cards
          received in respect of investments comprised in the Portfolio.

64.  TERMINATION OF AGREEMENT

     (a)  The Agreement is terminable by the Client without penalty and without
          prejudice to the completion of transaction already initiated and will
          continue until terminated by written notice of termination given at
          any time and in any circumstances by either party to the other. Notice
          of termination given by either party shall take effect on the day upon
          which the other party actually receives the notice (the "Termination
          Date") provided that, where the Client is a

                                                           Page 198 of 258 Pages
<PAGE>
 
          joint account, notice of termination by JOHIM shall be given to every
          person named in the joint account. In such circumstances the
          Termination Date shall be deemed to be the day after the date of
          posting by first class recorded delivery or other appropriate means to
          all persons named in the joint account.

     (b)  Upon the Termination Date, JOHIM's responsibility for the management
          of the portfolio will terminate forthwith and JOHIM will not execute
          any further transactions for the Client (except for transactions
          initiated, but not completed, upon the Termination Date). Upon all
          fees, commissions, expenses and other sums due to it and any other
          liabilities for which it may be or become liable in connection with
          the management of the portfolio being settled or adequately secured to
          the satisfaction of JOHIM, JOHIM will procure that all investments and
          cash balances held on the Client's behalf will, after any outstanding
          security registrations, stock exchange settlements and other
          administrative matters have been completed and as soon as reasonably
          practicable, be transferred to the Client or dealt with in accordance
          with the Client's instructions.

     (c)  No additional payment will be required to be made to JOHIM by the
          Client in respect of the termination of this Agreement, except that
          JOHIM may charge the Client an amount equal to:

          i.   the relevant proportion of the management fee, corresponding to
               that party of the period of six months ending on 30th April or
               31st October of each year by reference to which fees are payable,
               which has expired when this Agreement is terminated;

          ii.  any additional expenses which JOHIM necessarily incurs in
               terminating this Agreement; and

          iii  any losses necessarily realized in settling or concluding
               outstanding obligations.

     (d)  The death, bankruptcy or other incapacity or, in the case of a body
          corporate, the cessation of business of the Client or a petition being
          presented or a meeting being convened to consider a resolution for the
          liquidation of the Client shall not of itself terminate JOHIM's
          appointment; but JOHIM may at its discretion treat its receipt of
          actual notice of any such events as if it were a written notice of
          termination from the Client.

65.  RESPONSIBILITY AND INSURANCE

     (a)  JOHIM will indemnify the Client in respect of any loss incurred as a
          result of gross negligence, wilful default or fraud by JOHIM or any of
          its employees. Subject to the above, JOHIM will not be responsible or
          liable for any claim, loss, damage, expense or costs arising by reason
          of any of the following:

          i.   any investment decision taken and acted upon in accordance with
               the terms of this Agreement; or



                                                           Page 199 of 258 Pages
<PAGE>
 
          ii.  any delay or default in the performance of its obligations under
               this Agreement arising in consequence of any event or
               circumstance beyond the reasonable control of JOHIM; or

          iii  any act or omission on the part of the Bank or its nominee
               company or any person to which either of them shall have
               delegated its function or on the part of any other third party
               whatsoever; or

          iv.  any consequential loss suffered in consequence of any act or
               omission of JOHIM or any breach by JOHIM of any term of this
               Agreement.

     (b)  The Client agrees to indemnify and keep indemnified JOHIM from and
          against all demands, claims, liabilities, losses, damages, costs and
          expenses whatsoever incurred by JOHIM arising out of the breach by the
          Client of any warranty, by reason of any failure by the Client to
          comply with and/or perform any of the terms and conditions, contained
          in this Agreement.

     (c)  Where the Client is a joint account (whether or not a trust account)
          JOHIM shall unless and until otherwise directed in writing by all the
          persons named in the joint account, be entitled to act on the
          instructions of any of them and shall not in any way whatsoever be
          liable to the others for doing so.

     (d)  JOHIM has effected insurance to provide protection of the Client
          against losses arising from any negligence of JOHIM, any dishonest of
          employees of JOHIM or the dealing by JOHIM in any securities the
          documents of title to which have been stolen or forged.

     (e)  By Section 54 of the Finance Services Act 1986 The Securities and
          Investments Board may establish a scheme for compensating investors by
          which the Client may be entitled to compensation in the event of
          JOHIM's inability to meet any liabilities to the Client. Upon the
          establishment of such a scheme JOHIM will make available to the Client
          upon request a statement describing the Client's rights to
          compensation under the scheme.

66.  ACTING AS PRINCIPAL

JOHIM may act as principal in any transaction for the Client provided that JOHIM
shall secure for the Client best execution of such transaction and provided
that, in each instance, the Client's written consent is first obtained.

67.  GENERAL

     (a)  The Client warrants that the Client is the beneficial owner of the
          whole of the Portfolio free from all liens and encumbrances and will
          so remain during the currency of the Agreement.

                                                           Page 200 of 258 Pages

<PAGE>
 
     (b)  No part of the Portfolio or of the income therefrom shall be or become
          a beneficial asset of JOHIM except to the extent that the Capital
          Account is debited on the Client's behalf with the amount of fees,
          commissions, costs, expenses or other sums owed to JOHIM.

     (c)  The Client warrants that the Client is empowered to enter into this
          Agreement without the consent or authority of any other party and in
          the case of a Client being a body corporate the Client warrants that
          by entering into this Agreement it is not nor will it be in breach of
          its Memorandum or Articles of Association or any other relevant
          document.

     (d)  Documents will be sent to the Client at the address given above unless
          and until otherwise directed in writing. Copies of contract notes and
          statements may also be sent to other interested parties upon the
          Client's written request. The Client will immediately notify JOHIM in
          writing of any changes of address, and JOHIM cannot be held
          responsible for any consequences which may arise from failure to do
          so.

     (e)  Notice required or authorized to be served hereunder must be addressed
          to the address of the recipient stated above or to such other address
          as may have been notified in writing by either party hereto to the

          served by the client from outside the United Kingdom and of notice
          served upon the Client to an address outside the United Kingdom, the
          notice shall be sufficiently served if served by pre-paid letter,
          cable or telex. In the case of notice served by the Client from within
          the United Kingdom and of notice served upon the Client to an address
          within the United Kingdom, the notice shall be sufficiently served if
          served by pre-paid letter.

     (f)  This Agreement is subject to English law and the parties hereto hereby
          submit to the jurisdiction of the English courts in respect of it.

     (g)  Each party to this Agreement shall respect and protect the
          confidentiality of information acquired in consequence of it and shall
          not disclose such information to any third party save in the course of
          giving effect to this Agreement or as may be required by law.

     (h)  If the Client makes a complaint to JOHIM verbally or in writing about
          any service JOHIM has rendered to the Client under this Agreement the
          complain shall immediately be referred to JOHIM's Chief Executive or
          to a Senior Investment Manager who was not involved in the

          to rectify the matter complained of. The Client has the right to refer
          any complaint to IMRO if the Client is not satisfied with the action
          taken by the Chief Executive or Senior Investment Manager, and in any
          event has the right to make the complaint direct to IMRO without prior
          reference to JOHIM.

J O HAMBRO INVESTMENT
- ---------------------

THIS INVESTMENT MANAGEMENT AGREEMENT is made the 18th day of November 1991

BETWEEN:

(1)  J O HAMBRO INVESTMENT MANAGEMENT LIMITED ("JOHIM") a member of the
     Investment Management Regulatory Organisation Limited ("IMRO") whose
     registered office is at 30 Queen Anne's Gate London SW1H9AL; and

(2)  Viscount Althorp ("the Client") of The Falconry, Althorp, Northampton

NOW IT IS HEREBY AGREED as follows:

68.  APPOINTMENT

     The Client hereby appoints JOHIM to act as investment manager, subject to
     the terms and conditions hereof in relation to the Client's investments and
     cash which are from time to time placed under the management of JOHIM (the
     "Portfolio") and JOHIM hereby agrees to manage and administer the Portfolio
     and to render advice to the Client from time to time in connection with the
     Portfolio.  The Portfolio as at the date of this Agreement is comprised of
     the investments and cash as set out and valued in Schedule I.

69.  AUTHORISED BUSINESS

     The business which JOHIM is authorised by IMRO to conduct is the giving of
     investment advice in relation to, and the management of, the portfolios of
     private and business customers and the arranging of transactions relating
     to investments of any kind for all types of customers.

70.  MANAGEMENT OF INVESTMENTS

     (a)  JOHIM shall, subject to paragraph 3.2, have complete discretion, power
          and authority to manage the Portfolio and to make investments and
          changes in investments on the Client's behalf and as the Client's
          agent within the investment policy agreed between JOHIM and the Client
          and set out in Part I of Schedule II. Such policy shall be subject to
          the guidelines and restrictions set out in Part II of Schedule II and
          to any guidelines, restrictions and instructions specified in writing
          by the Client or by the Client's duly authorised agent (written notice
          of whose authority shall have been received by JOHIM). The Client's
          attention is specifically drawn to the warning set out in Part III of
          Schedule II.

     (b)  JOHIM may, at its discretion, by telephone or by letter and upon
          either JOHIM's or the Client's instigation give advice and receive and
          act upon instructions given by the Client from time to time, upon the
          investment policy relating to the portfolio and in relation to
          specific investments whether or not comprised in the Portfolio, which
          advice the Client shall not be obliged to follow. JOHIM may refuse to
          carry out any such instructions which appear to it to be unreasonable
          or the carrying out of which would, in JOHIM's opinion, adversely
          affect the Portfolio. JOHIM may, but shall not be obliged to, inform
          the Client of the basis on which the judgment leading to such advice
          is founded. (c) If in accordance with paragraph 3.2 JOHIM gives advice
          or receives and acts upon instructions in relation to specific
          investments, then JOHIM shall confirm such advice and/or action taken
          pursuant to such instructions in writing.

     (d)  JOHIM, its representatives and employees may, without the Client's
          express invitation, at any reasonable time call upon the Client either
          in person or by telephone whenever it considers it in the Client's
          interests to do so. The Client hereby forfeits its right under Section
          56 of the Financial Services Act 1986 to treat as unenforceable any
          investment agreement entered into in the course of or in consequence
          of such communication.

     (e)  JOHIM shall not be obliged to undertake the management of investments
          the management of which would in its opinion be onerous to it.
    
     (f)  (a)  Pursuant to the directions of the Client and save where the
               Client has notified JOHIM in accordance with paragraph 5.1(e), in
               those cases where the Client is situated in the United Kingdom
               registerable investments will be registered in the name of an
               eligible custodian situated in the United Kingdom and nominated
               by JOHIM.

     (b)  Pursuant to the directions of the Client, in those cases where the
          Client is situated overseas registerable investments will be
          registered in the name of an eligible custodian situated outside the
          United Kingdom and nominated by JOHIM.

     (c)  All documents of title (including those in bearer form) will be
          retained in the custody of an eligible custodian nominated by JOHIM
          and situated in the United Kingdom or overseas as applicable.

     (d)  None of the eligible custodians as aforesaid shall be Associates of
          JOHIM. However, the Client's registerable investments may at any time
          be registered in the name of an Associate of JOHIM and Client's
          documents of title may be held by an Associate of JOHIM, at any time
          after JOHIM shall have given the Client written notice of its
          intention to do so. Such notice shall specify the nature of its
          association with such Associate.

     (e)  JOHIM accepts no liability for any default by any eligible custodian
          as referred to in this paragraph.

                                                           Page 206 of 258 Pages
<PAGE>
 
     (g)  The Client's investments or documents of title or certificates
          evidencing title to investments or any other property belonging to the
          Client will not be lent by JOHIM to a third party except as otherwise
          agreed between the Client and JOHIM. JOHIM will not borrow money on
          the Client's behalf against the security of such investments,
          documents or property.

     (h)  Contract Notes in respect of every purchase and sale on the Client's
          behalf will be sent to the Client before the close of business on the
          day next following the day on which the transaction was effected.

     (i)  JOHIM will on the Client's request forward details of all transactions
          on the Client's behalf to the Client's tax advisor without additional
          charge.

     (j)  The Client understands that JOHIM's directors or staff may from time
          to time hold shares or securities including holdings that may be in
          the Portfolio.

     (k)  The Client acknowledges that JOHIM may acquire or dispose of on the
          Client's behalf shares or units in any fund, company, trust or
          Collective Investment Scheme (as defined by the Rules of IMRO) under
          JOHIM's management (or in a fund, company, trust or Collective
          Investment Scheme connected with JOHIM) if JOHIM considers such an
          investment to be appropriate for inclusion in the Portfolio.

     (l)  The Client may (upon giving reasonable notice) inspect all copy
          contract notes, vouchers and copies of entries in books or electronic
          recording media kept by JOHIM or to which JOHIM has access relating to
          the transactions effected by JOHIM on the Client's behalf and those
          records will be maintained by JOHIM or JOHIM will procure that they be
          maintained for not less than seven years from the date of the relevant
          transaction.

     (m)  JOHIM may, without prior reference to the Client, enter into a
          transaction on behalf of more than one client collectively.

     (n)  JOHIM has the right under this Agreement to effect transactions on the
          Client's behalf in investments the prices of which may be being
          stabilised. The attention of the Client is referred to the statement
          contained in Schedule II relating to stabilisation. Signature of this
          Agreement by or on behalf of the Client shall act as acknowledgment by
          the Client of receipt of such statement prior to entry into this
          Agreement.

71.  RESTRICTIONS AND PERMISSIONS

     (a)  Subject to paragraph 4.2, JOHIM shall not undertake any transactions
          on the Client's behalf in which JOHIM has directly or indirectly a
          material interest or have any relationship with another party which
          may involve a conflict with JOHIM's duty to the Client unless that
          interest or relationship has previously been disclosed in writing to
          the Client.

<PAGE>
 
     (b)  The Client's Portfolio may contain securities of which the issue or
          offer for sale is underwritten, managed or arranged by an Associate of
          JOHIM during the preceding twelve months.

     (c)  JOHIM may supplement the funds in the Portfolio by borrowing on the
          Client's behalf but only for the purpose of funding short-term
          deficiencies arising in the normal course of JOHIM's duties hereunder
          to an extent which is not material in the context of the Portfolio
          taken as a whole.

     (d)  JOHIM may commit the Client to any obligation to underwrite any issue
          or offer for sale of securities with the Client's prior written
          consent.

72.  ACCOUNTS, INTEREST AND DIVIDENDS

     (a)  The following Client accounts, together with such others that may be
          required, will be maintained by JOHIM. Such Client accounts will cover
          all Clients of JOHIM.

          i.   INVESTMENT ACCOUNT

          The Client's investments will be held in this account.  Subject to
          paragraphs 3.7 and 4.3, JOHIM shall not lend the Client's investments
          to any third party and shall not borrow money on the Client's behalf
          against the security of the Client's investments.

          ii.  CAPITAL ACCOUNT

          All uninvested cash will be held in this account by the Bank.  The
          account will be debited with the cost of purchases on the Client's
          behalf and with sums due and payable by the Client to JOHIM and will
          be credited with the net proceeds of sales on the Client's behalf.
          Money drawn on behalf of the Client from the account shall not exceed
          the total of money held in the account on behalf of the Client at that
          time.  Interest will be paid on sums standing to the credit of the
          account and held on the Client's behalf (as set out in Schedule III).
          The interest will be paid quarterly and will be credited to the Income
          Account on the Client's behalf.
      
          iii. SETTLEMENT ACCOUNT

          Money debited to the Capital Account in respect of the cost of
          purchases made on the Client's behalf and money received and

          will be credited to this account and held there until the relevant
          settlement date.

          iv.  INCOME ACCOUNT

          Dividends and interest received on investments within the Portfolio
          will be credited to this account.  Balances on the account will be
          paid away quarterly in accordance with the Client's instructions or,
          in the absence of such instructions, will be transferred quarterly to
          the Capital Account as soon as reasonably practicable after 

                                                           Page 208 of 258 Pages
<PAGE>
 
          the last day of each such quarter being 5th April, 30th June, 5th
          October and 31st December in each year. Money drawn on behalf of the
          Client from the account shall not exceed the total of money held in
          the account on behalf of the Client at that time. Interest will not be
          paid on monies held in this account.

          v.   OFF-SHORE FUNDS

          If the Client notifies JOHIM in writing that the Client wishes the
          investments and cash in the Portfolio to be registered or held outside
          the Untied Kingdom, JOHIM will (subject to applicable laws and
          regulations) hold such investments and cash in a bank account outside
          the United Kingdom.

     (b)  The Client may at any time instruct JOHIM to realise any or all of the
          investments in the Portfolio and may withdraw any sum standing to the
          credit of the Capital Account and held on the Client's behalf.

     (c)  JOHIM shall maintain separate ledger accounts on the Client's behalf.
          All debits from and credits to the Investment Account and/or Capital
          Account and/or Income Account on the Client's behalf shall be recorded
          in the ledger accounts, and statements of account showing all
          transactions, payments and receipts up to and including 5th April of
          each year will be sent to the Client as soon as reasonably practicable
          after that date.

73.  FEES, COMMISSIONS AND EXPENSES

     (a)  (a)  The Client will pay a management fee to JOHIM in respect of the
               period beginning with first receipt by JOHIM of any investments
               or money from the Client and ending with a Valuation Date (as
               defined in paragraph 7.2) and each period thereafter starting
               with the day after any Valuation Date and ending on the next
               Valuation Date (or the Termination Date [as defined in paragraph
               9.1] if sooner).

     (b)  The management fee shall be calculated in accordance with the "Scale
          Rates and Charges" set out in Schedule III.

     (c)  The management fee shall be payable within 14 days of dispatch to the
          Client of an invoice which shall be sent to the Client as soon as is
          reasonably practicable after each Valuation Date. Unless otherwise
          instructed the Client's Capital Account will be debited with the
          amounts due to JOHIM on the 14th day after dispatch of such invoice.

     (d)  In addition the Client shall reimburse JOHIM for any expenses or
          liabilities which it may incur in properly carrying out its duties
          hereunder.

     (b)  The management fee shall be deemed to have accrued on a day-to-day
          basis, so that, if this Agreement commences or terminates other than
          on a Valuation Date (as defined below), the amount of the fee shall be
          duly apportioned.

                                                           Page 209 of 258 Pages
<PAGE>
 
     (c)  Commissions (as set out in Schedule III) will be payable by the Client
          on purchases and sales of investments together with all expenses
          including stamp duties, stamp duty reserve tax and VAT thereon (if
          applicable). The Client recognises that JOHIM may gain a commission
          benefit from dealing in a bulk purchase or sale on behalf of JOHIM's
          clients, one of whom may be the Client, or from return commissions
          which benefit JOHIM shall be entitled to retain. JOHIM will be free to
          accept and retain as an addition to its fees and commissions any other
          commissions which it receives in the course of its dealing on the
          Client's behalf: all such benefits and receipts shall supplement any
          other remuneration receivable by JOHIM in connection with transactions
          effected by JOHIM with or for the Client under this or any other
          agreement with the Client and the Client consents to all such benefits
          and receipts as are referred to above without prior disclosure of the
          same to the Client on a case-by-case basis provided that JOHIM
          undertakes to secure for the Client best execution of all transactions
          effected with or through a party from whom JOHIM receives such
          benefits and commissions, disregarding any benefit which the Client
          might obtain directly or indirectly as a result of such arrangements.

     (d)  JOHIM shall be entitled to alter the manner of computing or charging
          its fees, commissions and expenses or of paying interest on the money
          held on the Client's behalf in the Capital Account on the Client's
          behalf (including without prejudice to the generality of the foregoing
          its scale rates and charges) by giving one month's prior notice in
          writing to the Client.

     (e)  All sums due and payable by the Client to JOHIM will be transferred as
          soon as practicable from the money held on the Client's behalf in the
          Capital Account (and corresponding entities shall be made in the
          relevant ledger account maintained on the Client's behalf).

74.  REVIEW AND VALUATIONS

     (a)  JOHIM will prepare six monthly statements of the Portfolio
          incorporating an up-to-date valuation of each investment comprised in
          the Portfolio and a statement of the basis on which it was valued.

     (b)  Such reviews shall be prepared as at such half yearly dates as shall
          be agreed between JOHIM and the Client from time to time (each such
          date being referred to as a "Valuation Date").

     (c)  JOHIM will send such six monthly reviews to the Client within twenty-
          five business days of each Valuation Date.

     (d)  On each Valuation Date cash will be valued at its face value and each
          investment will be valued at its middle market price on the relevant
          stock exchange at the close of business on such day or (if not a
          business day) on the nearest prior business day as is supplied by
          "Exshare" (which figures shall be binding save for manifest error).
          For the purpose of valuing in sterling any foreign currency or any
          security listed on a foreign stock exchange the price of which is
          quoted in currency

                                                           Page 210 of 258 Pages
<PAGE>
 
          other than sterling, the valuation and middle market exchange rates
          supplied by "Exshare" shall be applied. In the absence of that
          valuation or exchange rate, the middle market price as determined by
          the Daily Official List of The Stock Exchange or the equivalent list
          for any relevant stock exchange will be applied. if none of the
          foregoing methods of valuation are available, the investments in
          question will be valued in such other manner (by JOHIM or such other
          person selected by JOHIM) as shall in JOHIM's opinion be fair.

     (e)  JOHIM accepts no liability for any period longer than 25 business days
          between any Valuation Date and receipt by the Client of a review of
          his Portfolio which has elapsed as a result of any act or omission of
          any third party.
75.  VOTING AND OTHER RIGHTS

     JOHIM will be entitled at its discretion and without notice to the Client
     to exercise or to refrain from exercising voting and other rights and
     privileges attaching to the investments comprised in the Portfolio and to
     accede or refrain from acceding to any compromise or arrangement in
     relation to any scheme of arrangement or scheme for reconstruction or
     amalgamation involving any such investment. JOHIM will not forward to the
     Client any circulars, notices or proxy cards received in respect of
     investments comprised in the Portfolio.

76.  TERMINATION OF AGREEMENT

     (a)  This Agreement is terminable by the Client without penalty and without
          prejudice to the completion of transactions already initiated and will
          continue until terminated by written notice of termination given at
          any time and in any circumstances by either party to the other. Notice
          of termination given by either party shall take effect on the day upon
          which the other party actually receives the notice (the "Termination
          Date") provided that, where the Client is a joint account, notice of
          termination by JOHIM shall be given to every person named in the joint
          account. In such circumstances the Termination Date shall be deemed to
          be the day after the date of posting by first class recorded delivery
          or other appropriate means to all persons named in the joint account.

     (b)  Upon the Termination Date, JOHIM's responsibility for the management
          of the Portfolio will terminate forthwith and JOHIM will not execute
          any further transactions for the Client (except for transactions
          initiated, but not completed, upon the Termination Date). Upon all
          fees, commissions, expenses and other sums due to it and any other
          liabilities for which it may be or become liable in connection with
          the management of the Portfolio being settled or adequately secured to
          the satisfaction of JOHIM, JOHIM will ensure that all investments and
          cash balances held on the Client's behalf will, after any outstanding
          security registrations, stock exchange settlements and other
          administrative matters have been completed and as soon as reasonably
          practicable, be transferred to the Client or dealt with in accordance
          with the Client's instructions, in all cases at the cost of the
          Client.

<PAGE>
 
     (c)  No additional payment will be required to be made to JOHIM by the
          Client in respect of the termination of this Agreement, except that
          JOHIM may charge the Client an amount equal to:

          i.   the relevant proportion of the management fee, corresponding to
               that part of the period ending on a Valuation Date by reference
               to which fees are payable, which has expired when this Agreement
               is terminated;

          ii.  any additional expenses which JOHIM necessarily incurs in
               terminating this Agreement; and

          iii  any losses necessarily realised in settling or concluding
               outstanding obligations.

     (d)  The death, bankruptcy or other incapacity or, in the case of a body
          corporate, the cessation of business of the Client or a petition being
          presented or a meeting being convened to consider a resolution for the
          liquidation of the Client shall not of itself terminate JOHIM's
          appointment, but JOHIM may at its discretion treat its receipt of
          actual notice of any such events as if it were a written notice of
          termination from the Client.

77.  RESPONSIBILITY AND INSURANCE

     (a)  JOHIM will indemnify the Client in respect of any loss incurred as a
          result of gross negligence, wilful default or fraud by JOHIM or any of
          its employees. Subject to the above, JOHIM will not be responsible or
          liable fro any claim, loss, damage, expense or costs arising by reason
          of any of the following:

          i.   any investment decision taken and acted upon in accordance with
               the terms of this Agreement; or

          ii.  any delay or default in the performance of its obligations under
               this Agreement arising in consequence of any event or
               circumstance beyond the reasonable control of JOHIM; or

          iii  any act or omission on the part of any of the banks or nominee
               companies controlled by them or other eligible custodians as
               referred to in paragraph 3.6 or any other person to which any of
               them shall have delegated its function or on the part of any
               other third party whatsoever; or

          iv.  any consequential loss suffered in consequence of any act or
               omission of JOHIM or any breach by JOHIM of any term of this
               Agreement.

     (b)  The Client agrees to indemnify and keep indemnified JOHIM from and
          against all demands, claims, liabilities, losses, damages, costs and
          expenses whatsoever incurred by JOHIM arising out of the breach by the
          Client of any warranty, by reason of any failure by the Client to
          comply with and/or perform any of the terms and conditions contained
          in this Agreement.

<PAGE>
 
     (c)  Where the Client is a joint account (whether or not a trust account)
          JOHIM shall, unless and until otherwise directed in writing by all the
          persons named in the joint account, be entitled to act on the
          instructions of any of them and shall not in any way whatsoever be
          liable to the others for doing so.

     (d)  JOHIM has effected insurance to provide the protection of the Client
          against losses arising from any negligence of JOHIM, any dishonesty of
          employees of JOHIM or the dealing by JOHIM in any securities the
          documents of title to which have been stolen or forged.

     (e)  By Section 54 of the Financial Services Act 1986 The Securities and
          Investments Board may establish a scheme for compensating investors by
          which the Client may be entitled to compensation in the event of
          JOHIM's inability to meet any liabilities to the Client. Upon the
          establishment of such a scheme JOHIM will make available to the Client
          upon request a statement describing the Client's rights to
          compensation under the scheme.

78.  ACTING AS PRINCIPAL

     JOHIM may act as principal in any transaction for the Client provided that
     JOHIM shall secure for the Client best execution of such transaction and
     provided that, in each instance, the Client's written consent is first
     obtained.

79.  GENERAL

     (a)  The Client warrants that the Client is the beneficial owner of the
          whole of the Portfolio free from all liens and encumbrances, except
          insofar as instructed by the Client to JOHIM, and will so remain
          during the currency of this Agreement.

     (b)  No part of the Portfolio or of the income therefrom shall be or become
          a beneficial asset of JOHIM except to the extent that the Capital
          Account is debited on the Client's behalf with the amount of fees,
          commissions, costs, expenses or other sums owed to JOHIM.

     (c)  The Client warrants that the Client is empowered to enter into this
          Agreement without the consent or authority of any other party and in
          the case of a Client being a body corporate the Client warrants that
          by entering into this Agreement it is not nor will it be in breach of
          its Memorandum or Articles of Association or any other relevant
          document.

     (d)  Documents will be sent to the Client at the address given above unless
          and until otherwise directed in writing. Copies of contract notes and
          statements may also be sent to other interested parties upon the
          Client's written request. The Client will immediately notify JOHIM in
          writing of any changes of address, and JOHIM cannot be held
          responsible for any consequences which may arise from failure to do
          so.

     (e)  Notice required or authorised to be served hereunder must be addressed
          to the address of the recipient stated above or to such other address
          as may have been notified in writing by either party hereto to the
          other as its address for the service of notices. In the case of notice
          served by the Client from outside the United Kingdom and of notice
          served upon the Client to an address outside the United Kingdom, the
          notice shall be sufficiently served if served by pre-paid letter,
          cable or telex. In the case of notice served by the Client from within
          the United Kingdom and of notice served upon the Client to an address
          within the United Kingdom the notice shall be sufficiently served if
          served by pre-paid letter.

     (f)  This Agreement is subject to English law and the parties hereto hereby
          submit to the jurisdiction of the English Courts in respect of it.

     (g)  Each party to this Agreement shall respect and protect the
          confidentiality of information acquired in consequence of it and shall
          not disclose such information to any third party save in the course of
          giving effect to this Agreement or as may be required by law.

     (h)  If the Client makes a complaint to JOHIM verbally or in writing about
          any service JOHIM has rendered to the Client under this Agreement the
          complaint shall immediately be referred to JOHIM's Chief Executive or
          to a Senior Investment Manager who was not involved in the
          circumstances relating to the complaint and who will investigate such
          circumstances. Upon the conclusion of his investigation he shall make
          a written report to the Client and take any action he deems necessary
          to rectify the matter complained of. The Client has the fight to refer
          any complaint to IMRO if the Client is not satisfied with the action
          taken by the Chief Executive or Senior Investment Manager, and in any
          event has the right to make the complaint direct to IMRO without prior
          reference to JOHIM.

     (i)  If the Client is an individual this Agreement shall be binding on his
          legal personal representatives.
     
     (j)  This Agreement is personal to the parties  hereto and shall not be
          capable of assignment.

     (k)  No subsequent change, alteration or modification to this Agreement or
          the Schedules hereto shall be made unless in writing and signed by the
          parties hereto.
     
     (l)  JOHIM is a member of IMRO and as such is regulated by IMRO in the
          conduct of Investment Business (as defined in Section 1(2) of the
          Financial Services Act 1986).

     (m)  Terms and expressions defined in the rules of IMRO for the time being
          in force shall where the context so admits bear the same meaning in
          this Agreement.

     (n)  The Clause headings in this Agreement are included for ease of
          reference only and shall not affect its interpretation.

     (p)  This Agreement will come into force on the date and at the time on

                                 THE PORTFOLIO

    Valuation and composition of Portfolio as at the date of this Agreement
                    (See attached sheet - where applicable)

                      (Pounds)250,000 Received on 13-9-94

                                  SCHEDULE II

                INVESTMENT POLICY, GUIDELINES AND RESTRICTIONS

                  PART I - Investment Policy including basis
                         of measurement of performance

The investment objectives are to maintain a maximum total return commensurate
with safety and the protection of the underlying value of the capital of the
fund.

The performance will be measured against F.T. All Share Index or F.T.S.E. 100
Index or any other relevant World Market Index.

                     Part II - Guidelines and Restrictions

     There will be no restrictions placed on the types of investment in which
     the money comprised in the Portfolio will be invested provided that the
     services to be provided by JOHIM will not include advising on or effecting
     Margined Transactions, nor will they relate to futures or contracts for
     differences (or to any right or interest in such investments) save that we
     may in certain circumstances buy options on your behalf.  We may also close
     out an options contract at any time before its maturity, leave any such
     contract open until its maturity, exercise any option purchased through any
     options contract up to its expiry or allow any such option to expire
     unexercised.

     The contents of the Portfolio may be invested in any market save for the
     following:

     There shall be no restriction on the amount of monies or proportion of the
     Portfolio invested in any one investment or type of investment permitted
     hereunder provided that, subject to the provisions relating to overdraft
     contained in paragraph 4.3 of this Agreement, under no circumstances will
     JOHIM make investments on behalf of the Client to a value in excess of the
     aggregate of the value of the funds and securities held by JOHIM on behalf
     of the Client in the accounts referred to in paragraph 5.1 of this
     Agreement.

             PART II - Risk Warnings and Risk Disclosure Statement

                  Investment Denominated in Foreign Currencies

                                                           Page 216 of 258 Pages

<PAGE>
 
If a liability of the Client in one currency is to be matched by an asset in a
different currency, or if JOHIM provides services under this Agreement relating
to an investment denominated in a foreign currency, an investment in exchange
rates may have an effect which may be either unfavorable or favorable on the
investment, which effect may be separate from the gain or loss otherwise
experienced on such investment.

                      Investments not readily realisable

Certain categories of investments compromised in the Portfolio may not be
readily realisable. You should be aware that there can be no certainty that
market makers or brokers will be prepared to deal in such investments, and that
proper information for determining their current value may not be available.

                                    Options

The markets upon which options are traded can be highly volatile and such
investments carry a high risk of loss.  If we buy an option for the portfolio we
may, in our absolute discretion, and without prior reference to you, make
contractual or other arrangements or settle or close out outstanding
obligations.

                                 Stabilisation

This statement is made in compliance with Rule 14 of Chapter IV of the rules of
IMRO.

We or our representatives may from time to time recommend to you or effect on
your behalf transactions in securities the subject of a recent new issue the
price of which transactions may have been influenced by bids made or
transactions effected for the purpose of stabilising the price of those
securities.  You should read the explanation below carefully.  Its purpose is to
enable you to judge whether you wish your funds to be invested at all in such
securities or, if so, whether you wish to authorise us generally to effect
transactions in such securities on your behalf without further reference to you
or whether you wish to be consulted before any particular transaction is
effected on your behalf.

Stabilisation is a process whereby the market price of a security is pegged or
fixed during the period in which a new issue of securities is sold to the
public.  Stabilisation may take place in the new issue or in other securities
related to the new issue in such a way that the price of the other securities
may affect the price of the new issue or vice versa.

The reason stabilisation is permitted is that when a new issue is brought to
market the sudden glut will sometimes force the price lower for a period of time
before buyers are found for the securities on offer.

As long as he obeys a strict set of rules the "stabilising manager", normally
the issuing house chiefly responsible for bringing a new issue to market, is
entitled to buy securities in the market that he has previously sold to
investors or allotted to institutions who were included in the new issue but who
have decided not to continue participating.  The effect of this may be to keep
the price at a higher level than would otherwise be the case during the period
of stabilising.

                                                           Page 217 of 258 Pages

<PAGE>
 
These rules limit the period in which he may stabilise, fix the price at which
he may stabilise (in the case of shares and warrants but not bonds), and require
him to disclose that he may be (but not that he is) stabilising.

The fact that a new issue or a related security is being stabilised does not in
itself mean that investors are not interested in the issue, but neither should
the existence of transactions in an issue where stabilising may take place be
relied upon as an indication that investors are interested in the new issue or
interested in purchasing at the price at which transactions are taking place.

80.  APPOINTMENT

          agent within the investment policy agreed between JOHIM and the Client
          and set out in Part I of Schedule II. Such policy shall be subject to
          the guidelines and restrictions set out in Part II of Schedule II and
          to any guidelines, restrictions and instructions specified in writing
          by the Client or by the Client's duly authorised agent (written notice
          of whose authority shall have been received by JOHIM). The Client's
          attention is specifically drawn to the warning set out in Part III of
          Schedule II.

     (b)  JOHIM may, at its discretion, by telephone or by letter and upon
          either JOHIM's or the Client's instigation give advice and receive and
          act upon instructions given by the Client from time to time, upon the
          investment policy relating to the portfolio and in relation to
          specific investments whether or not comprised in the Portfolio,


                                                           Page 222 of 258 Pages

      which advice the Client shall not be obliged to follow. JOHIM may refuse
      to carry out any such instructions which appear to it to be unreasonable
      or the carrying out of which would, in JOHIM's opinion, adversely affect
      the Portfolio. JOHIM may, but shall not be obliged to, inform the Client
      of the basis on which the judgment leading to such advice is founded.

     (c)  If in accordance with paragraph 3.2 JOHIM gives advice or receives and
          acts upon instructions in relation to specific investments, then JOHIM
          shall confirm such advice and/or action taken pursuant to such
          instructions in writing.

     (d)  JOHIM, its representatives and employees may, without the Client's
          express invitation, at any reasonable time call upon the Client either
          in person or by telephone whenever it considers it in the Client's
          interests to do so. The Client hereby forfeits its right under Section
          56 of the Financial Services Act 1986 to treat as unenforceable any
          investment agreement entered into in the course of or in consequence
          of such communication.

     (e)  JOHIM shall not be obliged to undertake the management of investments
          the management of which would in its opinion be onerous to it.

     (f)  (a)  Pursuant to the directions of the Client and save where the
               Client has notified JOHIM in accordance with paragraph 5.1(e), in
               those cases where the Client is situated in the United Kingdom
               registerable investments will be registered in the name of an
               eligible custodian situated in the United Kingdom and nominated
               by JOHIM.

          (b)  Pursuant to the directions of the Client, in those cases where
               the Client is situated overseas registerable investments will be
               registered in the name of an eligible custodian situated outside
               the United Kingdom and nominated by JOHIM.

          (c)  All documents of title (including those in bearer form) will be
               retained in the custody of an eligible custodian nominated by
               JOHIM and situated in the United Kingdom or overseas as
               applicable.

          (d)  None of the eligible custodians as aforesaid shall be Associates
               of JOHIM. However, the Client's registerable investments may at
               any time be registered in the name of an Associate of JOHIM and
               Client's documents of title may be held by an Associate of JOHIM,
               at any time after JOHIM shall have given the Client written
               notice of its intention to do so. Such notice shall specify the
               nature of its association with such Associate. (e) JOHIM accepts
               no liability for any default by any eligible custodian as
               referred to in this paragraph.

          (g)  The Client's investments or documents of title or certificates
               evidencing title to investments or any other property belonging
               to the Client will not be lent by JOHIM to a third party except
               as otherwise agreed between the Client and


                                                           Page 223 of 258 Pages

               JOHIM. JOHIM will not borrow money on the Client's behalf
               against the security of such investments, documents or property.

          (h)  Contract Notes in respect of every purchase and sale on the
               Client's behalf will be sent to the Client before the close of
               business on the day next following the day on which the
               transaction was effected. 

          (i)  JOHIM will on the Client's request forward details of all
               transactions on the Client's behalf to the Client's tax advisor
               without additional charge.

          (j)  The Client understands that JOHIM's directors or staff may from
               time to time hold shares or securities including holdings that
               may be in the Portfolio.

          (k)  The Client acknowledges that JOHIM may acquire or dispose of on
               the Client's behalf shares or units in any fund, company, trust
               or Collective Investment Scheme (as defined by the Rules of IMRO)
               under JOHIM's management (or in a fund, company, trust or
               Collective Investment Scheme connected with JOHIM) if JOHIM
               considers such an investment to be appropriate for inclusion in
               the Portfolio.

          (l)  The Client may (upon giving reasonable notice) inspect all copy
               contract notes, vouchers and copies of entries in books or
               electronic recording media kept by JOHIM or to which JOHIM has
               access relating to the transactions effected by JOHIM on the
               Client's behalf and those records will be maintained by JOHIM or
               JOHIM will procure that they be maintained for not less than
               seven years from the date of the relevant transaction.

          (m)  JOHIM may, without prior reference to the Client, enter into a
               transaction on behalf of more than one client collectively.

          (n)  JOHIM has the right under this Agreement to effect transactions
               on the Client's behalf in investments the prices of which may be
               being stabilised. The attention of the Client is referred to the
               statement contained in Schedule II relating to stabilisation.
               Signature of this Agreement by or on behalf of the Client shall
               act as acknowledgment by the Client of receipt of such statement
               prior to entry into this Agreement.

83.  RESTRICTIONS AND PERMISSIONS

     (a)  Subject to paragraph 4.2, JOHIM shall not undertake any transactions
          on the Client's behalf in which JOHIM has directly or indirectly a
          material interest or have any relationship with another party which
          may involve a conflict with JOHIM's duty to the Client unless that
          interest or relationship has previously been disclosed in writing to
          the Client.

     (b)  The Client's Portfolio may contain securities of which the issue or
          offer for sale is underwritten, managed or arranged by an Associate of
          JOHIM during the preceding twelve months.

                                                           Page 224 of 258 Pages
<PAGE>
 
     (c)  JOHIM may supplement the funds in the Portfolio by borrowing on the
          Client's behalf but only for the purpose of funding short-term
          deficiencies arising in the normal course of JOHIM's duties hereunder
          to an extent which is not material in the context of the Portfolio
          taken as a whole. 

     (d)  JOHIM may commit the Client to any obligation to underwrite any issue
          or offer for sale of securities with the Client's prior written
          consent.

84.  ACCOUNTS, INTEREST AND DIVIDENDS

     (a)  The following Client accounts, together with such others that may be
          required, will be maintained by JOHIM. Such Client accounts will cover
          all Clients of JOHIM.

          i.   INVESTMENT ACCOUNT

          The Client's investments will be held in this account.  Subject to
          paragraphs 3.7 and 4.3, JOHIM shall not lend the Client's investments
          to any third party and shall not borrow money on the Client's behalf
          against the security of the Client's investments.

          ii.  CAPITAL ACCOUNT

          All uninvested cash will be held in this account by the Bank.  The
          account will be debited with the cost of purchases on the Client's
          behalf and with sums due and payable by the Client to JOHIM and will
          be credited with the net proceeds of sales on the Client's behalf.
          Money drawn on behalf of the Client from the account shall not exceed
          the total of money held in the account on behalf of the Client at that
          time.  Interest will be paid on sums standing to the credit of the
          account and held on the Client's behalf (as set out in Schedule III).
          The interest will be paid quarterly and will be credited to the Income
          Account on the Client's behalf.

          iii. SETTLEMENT ACCOUNT

          Money debited to the Capital Account in respect of the cost of
          purchases made on the Client's behalf and money received and
          receivable upon settlement of each sale made on the Client's behalf
          will be credited to this account and held there until the relevant
          settlement date.

          iv.  INCOME ACCOUNT

          Dividends and interest received on investments within the Portfolio
          will be credited to this account.  Balances on the account will be
          paid away quarterly in accordance with the Client's instructions or,
          in the absence of such instructions, will be transferred quarterly to
          the Capital Account as soon as reasonably practicable after the last
          day of each such quarter being 5th April, 30th June, 5th October and
          31st December in each year.  Money drawn on behalf of the Client from
          the account 


                                                           Page 225 of 258 Pages
<PAGE>
 
          shall not exceed the total of money held in the account on behalf of
          the Client at that time. Interest will not be paid on monies held in
          this account.

          v.   OFF-SHORE FUNDS

          If the Client notifies JOHIM in writing that the Client wishes the
          investments and cash in the Portfolio to be registered or held outside
          the Untied Kingdom, JOHIM will (subject to applicable laws and
          regulations) hold such investments and cash in a bank account outside
          the United Kingdom.

     (b)  The Client may at any time instruct JOHIM to realise any or all of the
          investments in the Portfolio and may withdraw any sum standing to the
          credit of the Capital Account and held on the Client's behalf.

     (c)  JOHIM shall maintain separate ledger accounts on the Client's behalf.
          All debits from and credits to the Investment Account and/or Capital
          Account and/or Income Account on the Client's behalf shall be recorded
          in the ledger accounts, and statements of account showing all
          transactions, payments and receipts up to and including 5th April of
          each year will be sent to the Client as soon as reasonably practicable
          after that date.

85.  FEES, COMMISSIONS AND EXPENSES

     (a)  (a)  The Client will pay a management fee to JOHIM in respect of the
               period beginning with first receipt by JOHIM of any investments
               or money from the Client and ending with a Valuation Date (as
               defined in paragraph 7.2) and each period thereafter starting
               with the day after any Valuation Date and ending on the next
               Valuation Date (or the Termination Date [as defined in paragraph
               9.1] if sooner).

     (b)  The management fee shall be calculated in accordance with the "Scale
          Rates and Charges" set out in Schedule III.

     (c)  The management fee shall be payable within 14 days of dispatch to the
          Client of an invoice which shall be sent to the Client as soon as is
          reasonably practicable after each Valuation Date. Unless otherwise
          instructed the Client's Capital Account will be debited with the
          amounts due to JOHIM on the 14th day after dispatch of such invoice.

     (d)  In addition the Client shall reimburse JOHIM for any expenses or
          liabilities which it may incur in properly carrying out its duties
          hereunder.

     (b)  The management fee shall be deemed to have accrued on a day-to-day
          basis, so that, if this Agreement commences or terminates other than
          on a Valuation Date (as defined below), the amount of the fee shall be
          duly apportioned.

     (c)  Commissions (as set out in Schedule III) will be payable by the Client
          on purchases and sales of investments together with all expenses
          including stamp duties, stamp


                                                           Page 226 of 258 Pages
<PAGE>
 
          duty reserve tax and VAT thereon (if applicable). The Client
          recognises that JOHIM may gain a commission benefit from dealing in a
          bulk purchase or sale on behalf of JOHIM's clients, one of whom may be
          the Client, or from return commissions which benefit JOHIM shall be
          entitled to retain. JOHIM will be free to accept and retain as an
          addition to its fees and commissions any other commissions which it
          receives in the course of its dealing on the Client's behalf: all such
          benefits and receipts shall supplement any other remuneration
          receivable by JOHIM in connection with transactions effected by JOHIM
          with or for the Client under this or any other agreement with the
          Client and the Client consents to all such benefits and receipts as
          are referred to above without prior disclosure of the same to the
          Client on a case-by-case basis provided that JOHIM undertakes to
          secure for the Client best execution of all transactions effected with
          or through a party from whom JOHIM receives such benefits and
          commissions, disregarding any benefit which the Client might obtain
          directly or indirectly as a result of such arrangements.

     (d)  JOHIM shall be entitled to alter the manner of computing or charging
          its fees, commissions and expenses or of paying interest on the money
          held on the Client's behalf in the Capital Account on the Client's
          behalf (including without prejudice to the generality of the foregoing
          its scale rates and charges) by giving one month's prior notice in
          writing to the Client.

     (e)  All sums due and payable by the Client to JOHIM will be transferred as
          soon as practicable from the money held on the Client's behalf in the
          Capital Account (and corresponding entities shall be made in the
          relevant ledger account maintained on the Client's behalf).

86.  REVIEW AND VALUATIONS

     (a)  JOHIM will prepare six monthly statements of the Portfolio
          incorporating an up-to-date valuation of each investment comprised in
          the Portfolio and a statement of the basis on which it was valued.

     (b)  Such reviews shall be prepared as at such half yearly dates as shall
          be agreed between JOHIM and the Client from time to time (each such
          date being referred to as a "Valuation Date").

     (c)  JOHIM will send such six monthly reviews to the Client within twenty-
          five business days of each Valuation Date.

     (d)  On each Valuation Date cash will be valued at its face value and each
          investment will be valued at its middle market price on the relevant
          stock exchange at the close of business on such day or (if not a
          business day) on the nearest prior business day as is supplied by
          "Exshare" (which figures shall be binding save for manifest error).
          For the purpose of valuing in sterling any foreign currency or any
          security listed on a foreign stock exchange the price of which is
          quoted in currency other than sterling, the valuation and middle
          market exchange rates supplied by "Exshare" shall be applied. In the
          absence of that valuation or exchange rate, the


                                                           Page 227 of 258 Pages
<PAGE>
 
          middle market price as determined by the Daily Official List of The
          Stock Exchange or the equivalent list for any relevant stock exchange
          will be applied. if none of the foregoing methods of valuation are
          available, the investments in question will be valued in such other
          manner (by JOHIM or such other person selected by JOHIM) as shall in
          JOHIM's opinion be fair.

     (e)  JOHIM accepts no liability for any period longer than 25 business days
          between any Valuation Date and receipt by the Client of a review of
          his Portfolio which has elapsed as a result of any act or omission of
          any third party.

87.  VOTING AND OTHER RIGHTS

     JOHIM will be entitled at its discretion and without notice to the Client
     to exercise or to refrain from exercising voting and other rights and
     privileges attaching to the investments comprised in the Portfolio and to
     accede or refrain from acceding to any compromise or arrangement in
     relation to any scheme of arrangement or scheme for reconstruction or
     amalgamation involving any such investment.  JOHIM will not forward to the
     Client any circulars, notices or proxy cards received in respect of
     investments comprised in the Portfolio.

88.  TERMINATION OF AGREEMENT

     (a)  This Agreement is terminable by the Client without penalty and without
          prejudice to the completion of transactions already initiated and will
          continue until terminated by written notice of termination given at
          any time and in any circumstances by either party to the other. Notice
          of termination given by either party shall take effect on the day upon
          which the other party actually receives the notice (the "Termination
          Date") provided that, where the Client is a joint account, notice of
          termination by JOHIM shall be given to every person named in the joint
          account. In such circumstances the Termination Date shall be deemed to
          be the day after the date of posting by first class recorded delivery
          or other appropriate means to all persons named in the joint account.

     (b)  Upon the Termination Date, JOHIM's responsibility for the management
          of the Portfolio will terminate forthwith and JOHIM will not execute
          any further transactions for the Client (except for transactions
          initiated, but not completed, upon the Termination Date). Upon all
          fees, commissions, expenses and other sums due to it and any other
          liabilities for which it may be or become liable in connection with
          the management of the Portfolio being settled or adequately secured to
          the satisfaction of JOHIM, JOHIM will ensure that all investments and
          cash balances held on the Client's behalf will, after any outstanding
          security registrations, stock exchange settlements and other
          administrative matters have been completed and as soon as reasonably
          practicable, be transferred to the Client or dealt with in accordance
          with the Client's instructions, in all cases at the cost of the
          Client.

     (c)  No additional payment will be required to be made to JOHIM by the
          Client in respect of the termination of this Agreement, except that
          JOHIM may charge the Client an amount equal to:

                                                           Page 228 of 258 Pages
<PAGE>
 
          i.   the relevant proportion of the management fee, corresponding to
               that part of the period ending on a Valuation Date by reference
               to which fees are payable, which has expired when this Agreement
               is terminated;

          ii.  any additional expenses which JOHIM necessarily incurs in
               terminating this Agreement; and

          iii. any losses necessarily realised in settling or concluding
               outstanding obligations.

     (d)  The death, bankruptcy or other incapacity or, in the case of a body
          corporate, the cessation of business of the Client or a petition being
          presented or a meeting being convened to consider a resolution for the
          liquidation of the Client shall not of itself terminate JOHIM's
          appointment, but JOHIM may at its discretion treat its receipt of
          actual notice of any such events as if it were a written notice of
          termination from the Client.

89.  RESPONSIBILITY AND INSURANCE

     (a)  JOHIM will indemnify the Client in respect of any loss incurred as a
          result of gross negligence, wilful default or fraud by JOHIM or any of
          its employees. Subject to the above, JOHIM will not be responsible or
          liable fro any claim, loss, damage, expense or costs arising by reason
          of any of the following:

          i.   any investment decision taken and acted upon in accordance with
               the terms of this Agreement; or

          ii.  any delay or default in the performance of its obligations under
               this Agreement arising in consequence of any event or
               circumstance beyond the reasonable control of JOHIM; or

          iii. any act or omission on the part of any of the banks or nominee
               companies controlled by them or other eligible custodians as
               referred to in paragraph 3.6 or any other person to which any of
               them shall have delegated its function or on the part of any
               other third party whatsoever; or

          iv.  any consequential loss suffered in consequence of any act or
               omission of JOHIM or any breach by JOHIM of any term of this
               Agreement.

     (b)  The Client agrees to indemnify and keep indemnified JOHIM from and
          against all demands, claims, liabilities, losses, damages, costs and
          expenses whatsoever incurred by JOHIM arising out of the breach by the
          Client of any warranty, by reason of any failure by the Client to
          comply with and/or perform any of the terms and conditions contained
          in this Agreement.

     (c)  Where the Client is a joint account (whether or not a trust account)
          JOHIM shall, unless and until otherwise directed in writing by all the
          persons named in the joint

          account, be entitled to act on the instructions of any of them and
          shall not in any way whatsoever be liable to the others for doing so.

     (d)  JOHIM has effected insurance to provide the protection of the Client
          against losses arising from any negligence of JOHIM, any dishonesty of
          employees of JOHIM or the dealing by JOHIM in any securities the
          documents of title to which have been stolen or forged.

     (e)  By Section 54 of the Financial Services Act 1986 The Securities and
          Investments Board may establish a scheme for compensating investors by
          which the Client may be entitled to compensation in the event of
          JOHIM's inability to meet any liabilities to the Client. Upon the
          establishment of such a scheme JOHIM will make available to the Client
          upon request a statement describing the Client's rights to
          compensation under the scheme.

90.  ACTING AS PRINCIPAL

     JOHIM may act as principal in any transaction for the Client provided that
     JOHIM shall secure for the Client best execution of such transaction and
     provided that, in each instance, the Client's written consent is first
     obtained.

91.  GENERAL

     (a)  The Client warrants that the Client is the beneficial owner of the
          whole of the Portfolio free from all liens and encumbrances, except
          insofar as instructed by the Client to JOHIM, and will so remain
          during the currency of this Agreement.

     (b)  No part of the Portfolio or of the income therefrom shall be or become
          a beneficial asset of JOHIM except to the extent that the Capital
          Account is debited on the Client's behalf with the amount of fees,
          commissions, costs, expenses or other sums owed to JOHIM.

     (c)  The Client warrants that the Client is empowered to enter into this
          Agreement without the consent or authority of any other party and in
          the case of a Client being a body corporate the Client warrants that
          by entering into this Agreement it is not nor will it be in breach of
          its Memorandum or Articles of Association or any other relevant
          document.

     (d)  Documents will be sent to the Client at the address given above unless
          and until otherwise directed in writing. Copies of contract notes and
          statements may also be sent to other interested parties upon the
          Client's written request. The Client will immediately notify JOHIM in
          writing of any changes of address, and JOHIM cannot be held
          responsible for any consequences which may arise from failure to do
          so.

     (e)  Notice required or authorised to be served hereunder must be addressed
          to the address of the recipient stated above or to such other address
          as may have been notified in writing by either party hereto to the
          other as its address for the service

          of notices. In the case of notice served by the Client from outside
          the United Kingdom and of notice served upon the Client to an address
          outside the United Kingdom, the notice shall be sufficiently served if
          served by pre-paid letter, cable or telex. In the case of notice
          served by the Client from within the United Kingdom and of notice
          served upon the Client to an address within the United Kingdom the
          notice shall be sufficiently served if served by pre-paid letter.

          submit to the jurisdiction of the English Courts in respect of it.

          not disclose such information to any third party save in the course of
          giving effect to this Agreement or as may be required by law.

     (h)  If the Client makes a complaint to JOHIM verbally or in writing about
          any service JOHIM has rendered to the Client under this Agreement the
          complaint shall immediately be referred to JOHIM's Chief Executive or
          to a Senior Investment Manager who was not involved in the
          circumstances relating to the complaint and who will investigate such
          circumstances. Upon the conclusion of his investigation he shall make
          a written report to the Client and take any action he deems necessary
          to rectify the matter complained of. The Client has the fight to refer
          any complaint to IMRO if the Client is not satisfied with the action
          taken by the Chief Executive or Senior Investment Manager, and in any
          event has the right to make the complaint direct to IMRO without prior
          reference to JOHIM.

     (i)  If the Client is an individual this Agreement shall be binding on his
          legal personal representatives.

     (j)  This Agreement is personal to the parties  hereto and shall not be
          capable of assignment.

     (k)  No subsequent change, alteration or modification to this Agreement or

          this Agreement.

     (n)  The Clause headings in this Agreement are included for ease of
          reference only and shall not affect its interpretation.

     (o)  The Schedules to this Agreement are an integral part of it.

     (p)  This Agreement will come into force on the date and at the time on

                                 THE PORTFOLIO

    Valuation and composition of Portfolio as at the date of this Agreement
                    (See attached sheet - where applicable)

                                  SCHEDULE II

                 INVESTMENT POLICY, GUIDELINES AND RESTRICTIONS

                   PART I - Investment Policy including basis
                         of measurement of performance

The investment objectives are to maintain a maximum total return commensurate
with safety and the protection of the underlying value of the capital of the
fund.

The performance will be measured against F.T. All Share Index or F.T.S.E. 100
Index or any other relevant World Market Index.

                     Part II - Guidelines and Restrictions

     There will be no restrictions placed on the types of investment in which
     the money comprised in the Portfolio will be invested provided that the
     services to be provided by JOHIM will not include advising on or effecting
     Margined Transactions, nor will they relate to futures or contracts for
     differences (or to any right or interest in such investments) save that we
     may in certain circumstances buy options on your behalf.  We may also close
     out an options contract at any time before its maturity, leave any such
     contract open until its maturity, exercise any option purchased through any
     options contract up to its expiry or allow any such option to expire
     unexercised.

     The contents of the Portfolio may be invested in any market save for the
     following:

     There shall be no restriction on the amount of monies or proportion of the
     Portfolio invested in any one investment or type of investment permitted
     hereunder provided that, subject to the provisions relating to overdraft
     contained in paragraph 4.3 of this Agreement, under no circumstances will
     JOHIM make investments on behalf of the Client to a value in excess of the
     aggregate of the value of the funds and securities held by JOHIM on behalf
     of the Client in the accounts referred to in paragraph 5.1 of this
     Agreement.

             PART II - Risk Warnings and Risk Disclosure Statement

                  Investment Denominated in Foreign Currencies


                                                           Page 233 of 258 Pages
<PAGE>
 
If a liability of the Client in one currency is to be matched by an asset in a
different currency, or if JOHIM provides services under this Agreement relating
to an investment denominated in a foreign currency, an investment in exchange
rates may have an effect which may be either unfavorable or favorable on the
investment, which effect may be separate from the gain or loss otherwise
experienced on such investment.

                      Investments not readily realisable

Certain categories of investments compromised in the Portfolio may not be
readily realisable. You should be aware that there can be no certainty that
market makers or brokers will be prepared to deal in such investments, and that
proper information for determining their current value may not be available.

                                    Options

The markets upon which options are traded can be highly volatile and such
investments carry a high risk of loss.  If we buy an option for the portfolio we
may, in our absolute discretion, and without prior reference to you, make
contractual or other arrangements or settle or close out outstanding
obligations.

                                 Stabilisation

This statement is made in compliance with Rule 14 of Chapter IV of the rules of
IMRO.

We or our representatives may from time to time recommend to you or effect on
your behalf transactions in securities the subject of a recent new issue the
price of which transactions may have been influenced by bids made or
transactions effected for the purpose of stabilising the price of those
securities.  You should read the explanation below carefully.  Its purpose is to
enable you to judge whether you wish your funds to be invested at all in such
securities or, if so, whether you wish to authorise us generally to effect
transactions in such securities on your behalf without further reference to you
or whether you wish to be consulted before any particular transaction is
effected on your behalf.

Stabilisation is a process whereby the market price of a security is pegged or
fixed during the period in which a new issue of securities is sold to the
public.  Stabilisation may take place in the new issue or in other securities
related to the new issue in such a way that the price of the other securities
may affect the price of the new issue or vice versa.

The reason stabilisation is permitted is that when a new issue is brought to
market the sudden glut will sometimes force the price lower for a period of time
before buyers are found for the securities on offer.

As long as he obeys a strict set of rules the "stabilising manager", normally
the issuing house chiefly responsible for bringing a new issue to market, is
entitled to buy securities in the market that he has previously sold to
investors or allotted to institutions who were included in the new issue but who
have decided not to continue participating.  The effect of this may be to keep
the price at a higher level than would otherwise be the case during the period
of stabilising.


                                                           Page 234 of 258 Pages
<PAGE>
 
These rules limit the period in which he may stabilise, fix the price at which
he may stabilise (in the case of shares and warrants but not bonds), and require
him to disclose that he may be (but not that he is) stabilising.

The fact that a new issue or a related security is being stabilised does not in
itself mean that investors are not interested in the issue, but neither should
the existence of transactions in an issue where stabilising may take place be
relied upon as an indication that investors are interested in the new issue or
interested in purchasing at the price at which transactions are taking place.

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

NOW IT IS HEREBY AGREED as follows:

APPOINTMENT AND STATUS OF CLIENT

92.  The Client, a private customer as defined in the rules of IMRO, hereby
     appoints JOHIM to act as discretionary investment manager, subject to the
     terms and conditions hereof, in relation to the Client's investments and
     cash which are from time to time placed under the management of JOHIM (the
     "Portfolio") and JOHIM hereby agrees to manage and administer the
     Portfolio.  The appointment will commence on the date on which this
     Agreement is delivered to JOHIM by the Client having been signed first by
     the Client then by JOHIM.  The assets comprising the Portfolio and their
     opening value are set out in Schedule 1.

MANAGEMENT OF INVESTMENTS

93.  JOHIM shall have complete discretion, power and authority to manage the
     Portfolio and to make investments and changes in investments on the
     Client's behalf and as the Client's agent within the investment policy
     agreed between JOHIM and the Client and set our in Part I of Schedule II.
     Such policy shall be subject to the guidelines and restrictions set out in
     Part II of Schedule II and to any guidelines, restrictions and instructions
     specified in writing from time to time by the Client or by the Client's
     duly authorised agent (written notice of whose authority shall have been
     received by JOHIM).  The Client's attention is specifically drawn to the
     warnings set out in Part III of Schedule II.

94.  JOHIM shall not be obliged to undertake the management of investments the
     management of which would in its opinion be onerous to it.

DEALING TERMS

95.  In effecting transactions for the Portfolio JOHIM shall seek best execution
     at all times and may (subject to the investment policy set out in Part I of
     Schedule II) deal on such

     Client agrees that all such transactions will be effected in accordance

     and regulations and/or by good market practice.

96.  The Client's investments or documents of title or certificates evidencing
     title to investments or any other property belonging to the Client will not
     be lent by JOHIM to a third party except as otherwise agreed between the
     Client and JOHIM.

97.  JOHIM may supplement the funds in the Portfolio by borrowing on the
     Client's behalf but only for the purpose of funding short-term deficiencies
     arising in the normal course of JOHIM's duties hereunder to an extent which
     is not material in the context of the Portfolio taken as a whole.  JOHIM
     will not borrow money on the Client's behalf against the security of any of
     the Client's investments, documents of title or property.

98.  JOHIM shall only commit the Client to any obligation to underwrite any
     issue or offer for sale of securities with the Client's prior written

     Client's behalf in investments the price of which may be being stabilised.
     The attention of the Client is referred to the statement contained in

     on behalf of the Client shall act as acknowledgment by the Client of
     receipt of such statement prior to entry into this Agreement.

     relationship is disclosed in writing to the Client.

103. The Client's Portfolio may contain securities of which the issue or offer
     for sale is underwritten, managed or arranged by an Associate (as defined
     in the Rules of IMRO) of JOHIM during the preceding twelve months.

104. The Client understands that JOHIM's directors or staff may from time to
     time hold shares or securities including holdings that may be in the
     Portfolio, and that JOHIM's directors or staff may from time to time be
     directors or companies whose shares are held in the Portfolio.

105. The Client acknowledges that JOHIM may acquire or dispose of on the
     Client's behalf shares or units in any fund, company, trust or Collective
     Investment Scheme (as 


                                                           Page 240 of 258 Pages
<PAGE>
 
     defined by the Rules of IMRO) under JOHIM's management (or in a fund,
     company, trust or Collective Investment Scheme connected with JOHIM) if
     JOHIM considers such an investment to be appropriate for inclusion in or
     exclusion from the Portfolio.

          Eligible Custodian (as defined in the Rules of IMRO) situated in the
          United Kingdom and nominated by JOHIM.

     (b)  In those cases where the Client is situated overseas or where the
          Client so requests by notice in writing to JOHIM, registerable

          situated outside the United Kingdom and nominated by JOHIM.

     (c)  All documents of title (including those in bearer form) will be
          retained in the custody of an Eligible Custodian nominated by JOHIM
          and situated in the United Kingdom or overseas as applicable.

     (d)  None of the Eligible Custodians as aforesaid shall be Associates of
          JOHIM. However, the Client's registerable investments may at any time
          be registered in the name of a nominee company which is an Associate
          of JOHIM and Client's documents of title may be held by that Associate
          at any time after JOHIM shall have given the Client written notice of
          its intention to do so. Such notice shall specify the nature of its
          association with such Associate.

ACCOUNTS, INTERESTS AND DIVIDENDS

107. The following Client accounts, together with such others that may be
     required, will be maintained by JOHIM.  Such Client accounts will cover all
     Clients of JOHIM:

     (a)  INVESTMENT ACCOUNT

          The Client's investments will be held in this account.  Subject to
          paragraphs 5 and 6, JOHIM shall not lend the Client's investments to
          any third party and shall not borrow money on the Client's behalf
          against the security of the Client's investments.

     (b)  CAPITAL ACCOUNT

          All uninvested cash will be held in this account by a bank chosen by
          JOHIM. The account will be debited with the cost of purchases on the
          Client's behalf and with sums due and payable by the Client to JOHIM
          and will be credited with the net proceeds of sales on the Client's
          behalf.  Money drawn on behalf of the Client from the account shall
          not exceed the total of money held in the 


                                                           Page 241 of 258 Pages
<PAGE>
 
          account on behalf of the Client at that time. Interest will be paid on
          sums standing to the credit of the account and held on the Client's
          behalf (as set our in Schedule III). The interest will be paid
          quarterly and will be credited to the Income Account on the Client's
          behalf.

     (c)  SETTLEMENT ACCOUNT

          Money debited to the Capital Account in respect of the cost of
          purchases made on the Client's behalf and money received and
          receivable upon settlement of each sale made on the Client's behalf
          will be credited to this account and held there until the relevant
          settlement date.

     (d)  INCOME ACCOUNT

          Dividends and interest received on investments within the Portfolio
          will be credited to this account.  Balances on the account will be
          paid away quarterly in accordance with the Client's instructions or,
          in the absence of such instructions, will be transferred quarterly to
          the Capital Account as soon as reasonably practicable after the last
          day of each such quarter being 5th April, 30th June, 5th October and
          31st December in each year.  Money drawn on behalf of the Client from
          the account shall not exceed the total of money held in the account on
          behalf of the Client at that time.  Interest will not be paid on
          monies held in this account.

     (e)  OFF-SHORE FUNDS

          In those cases where the Client is situated overseas or if the Client
          notifies JOHIM in writing that the Client wishes cash in the Portfolio
          to be held outside the United Kingdom, JOHIM will be (subject to
          applicable laws and regulations) hold such cash in a bank account
          outside the United Kingdom.

108. The Client may at any time instruct JOHIM to realise any or all of the
     investments in the Portfolio and may withdraw any sum standing to the
     credit of the Capital Account and held on the Client's behalf.

109. JOHIM shall maintain separate ledger accounts on the Client's behalf.  All
     debits from and credits to the Investment Account and/or Capital Account
     and/or Income Account on the Client's behalf shall be recorded in the ledge
     accounts, and statements of account showing all transactions, payments and
     receipts up to and including 5th April of each year will be sent to the
     Client as soon as reasonably practicable after that date.

COMMUNICATIONS

110. In the interests of proper administration of the Portfolio and for related
     investment purposes JOHIM, its representatives or employees, may call upon
     the client by telephone, visit or otherwise communicate orally with the
     Client without express invitation.  The Client's attention is drawn to the
     fact that the Client will forfeit any right conferred by section 56 of the
     Financial Services Act 1986 to treat as 


                                                           Page 242 of 258 Pages
<PAGE>
 
     unenforceable any investment agreement entered into in the course of or in
     consequence of such a call.

ADMINISTRATION

111. Contract Notes in respect of every purchase and sale on the Client's behalf
     will be sent to the Client before the close of business on the day next
     following the day on which the transaction was effected.

112. JOHIM will be on the Client's request forward details of all transactions
     on the Client's behalf to the Client's tax advisor without additional
     charge.

113. The Client may (upon giving reasonable notice) inspect all copy contract
     notes, vouchers and copies of entries in books or electronic recording
     media kept by JOHIM or to which JOHIM has access relating to the
     transactions effected by JOHIM on the Client's behalf and those records
     will be maintained by JOHIM or JOHIM will ensure that they are maintained
     for not less than seven years from the date of the relevant transaction.

114. All documents will be sent to the Client at the address given above unless
     and until otherwise directed in writing.  The Client agrees that it will
     immediately notify JOHIM in writing of any changes of address, and that
     JOHIM will not be responsible for any consequences which may arise from
     failure to do so.

REVIEWS AND VALUATIONS

115. JOHIM will prepare six monthly reviews of the Portfolio incorporating an
     up-to-date valuation of each investment comprised in the Portfolio and a
     statement of the basis on which it was valued.  Such reviews shall be
     prepared as at such half yearly dates as shall be agreed between JOHIM and
     the Client from time to time (each such date being referred to as a
     "Valuation Date"), and JOHIM will send six monthly reviews to the Client
     within twenty-five business days of each Valuation Date.

116. On each Valuation Date cash will be valued at its face value and each
     investment will be valued at its middle market price on the relevant stock
     exchange at the close of business on such day or (if not a business day) on
     the nearest prior business day as is supplied by "Exshare" or any other
     suitable information service chosen by JOHIM (which figures shall be
     binding save for manifest error).  For the purpose of valuing in sterling
     any foreign currency or any security listed on a foreign stock exchange the
     price of which is quoted in currency other than sterling, the valuation and
     middle market exchange rates supplied by "Exshare" or any other suitable
     information service chosen by JOHIM shall be applied.  In the absence of
     that valuation or exchange rate, the middle market price as determined by
     the Daily Official List of The Stock Exchange or the equivalent list for
     any relevant stock exchange will be applied.  If none of the foregoing
     methods of valuation are available, the investments in question will be
     valued in such other manner (by JOHIM or such other person selected by
     JOHIM) as shall in JOHIM's opinion be fair.


                                                           Page 243 of 258 Pages
<PAGE>
 
117. JOHIM accepts no liability for any period longer than 25 business days
     between any Valuation Date and the despatch of a review to the Client of
     his Portfolio which has elapsed as a result of any  act or omission of any
     third party.

VOTING AND OTHER RIGHTS

118. JOHIM will be entitled at its discretion and without notice to the Client
     to procure or to refrain from procuring the exercise of voting and other
     rights and privileges attaching to the investments comprised in the
     Portfolio and to accede or refrain from acceding to any compromise or
     arrangement in relation to any scheme of arrangement or scheme for
     reconstruction or amalgamation involving any such investment.  JOHIM will
     not forward to the Client any circulars, notices or proxy cards received in
     respect of investments comprised in the Portfolio.

FILES, COMMISSIONS AND EXPENSES

119.
     (a)  The Client will pay a management fee to JOHIM in respect of the period
          beginning with first receipt by JOHIM of any investments or money from
          the Client and ending with a Valuation Date (as defined in paragraph
          24) and each period thereafter starting with the day after any
          Valuation Date and ending on the next Valuation Date (or the
          Termination Date as defined in paragraph 39 if sooner).

     (b)  The management fee shall be calculated in accordance with the 'Scale
          Rates and Charges' set out in Schedule III.

     (c)  The management fee shall be payable not later than 14 days after
          despatch to the Client of an invoice which shall be sent to the Client
          as soon as is reasonably practicable after each Valuation Date. Unless
          otherwise instructed the Client's Capital Account will be debited with
          the amounts due to JOHIM on the 14th day after despatch of such
          notice.

     (d)  In addition the Client shall reimburse JOHIM for any expenses or
          liabilities which it may incur in properly carrying out its duties
          hereunder.

120. The management fee shall be deemed to have accrued on a day-to-day basis,
     so that, if this Agreement commences or terminates other than on a
     Valuation Date (as defined in paragraph 24), the amount of the fee shall be
     duly apportioned.

121. Commissions (as set out in Schedule III) will be payable by the Client on
     purchases and sales of investments together with all expenses including
     stamp duties, stamp duty reserve tax and VAT thereon (if applicable).  The
     Client recognises that JOHIM may gain a commission benefit from dealing in
     a bulk purchase or sale on behalf of JOHIM's clients, one of whom may be
     the Client, or from return commissions which benefit JOHIM shall be
     entitled to retain.  JOHIM will be free to accept and retain as an addition
     to its fees and commissions any other commissions which it receives in the
     course of dealing on the Client's behalf; all such benefits and receipts
     shall supplement 


                                                           Page 244 of 258 Pages
<PAGE>
 
     any other remuneration receivable by JOHIM in connection with transactions
     effected by JOHIM with or for the Client under this or any other agreement
     with the Client and the Client consents to all such benefits and receipts
     as are referred to above without prior disclosure of the same to the Client
     on a case-by-case basis provided that JOHIM undertakes to secure for the
     Client best execution of all transactions effected with or through a party
     from whom JOHIM receives such benefits and commissions, disregarding any
     benefit which the Client might obtain directly or indirectly as a result of
     such arrangements.

122. JOHIM shall be entitled to alter the manner of computing or charging its
     fees, commissions and expenses or of paying interest on the money held on
     the Client's behalf in the Capital Account (including with prejudice to the
     generality of the foregoing its scale rates and charges) by giving one
     month's prior notice in writing to the Client.

RESPONSIBILITY AND INSURANCE

123. JOHIM will indemnify the Client in respect of any loss incurred as a result
     of negligence, wilful default or fraud by JOHIM or any of its employees.
     Subject to the above, JOHIM will not be responsible or liable for any
     claim, loss, damage, expense or costs arising by reason of any of the
     following:

     (a)  any investment decision taken and acted upon in accordance with the
          terms of this Agreement; or

     (b)  any delay or default in the performance of its obligations under this
          Agreement arising in consequence of any event or circumstance beyond
          the reasonable control of JOHIM; or

     (c)  any act or omission on the part of any of the banks or nominee
          companies controlled by them or other eligible custodians as referred
          to in paragraph 156 or any other person to which any of them shall
          have delegated its function or on the part of any other third party
          whatsoever; or

     (d)  any consequential loss suffered in consequence of any act or omission
          or JOHIM or any breach of JOHIM of any term of this Agreement.

124. The Client agrees to indemnify and keep indemnified JOHIM from and against
     all demands, claims, liabilities, losses, damages, costs and expenses
     whatsoever incurred by JOHIM arising out of the breach by the Client of any
     warranty or by reason of any failure by the Client to comply with and/or
     perform any of the terms and conditions contained in this Agreement.

125. Where the Client is a joint account (whether or not a trust account) JOHIM
     shall unless and until otherwise directed in writing by all the persons
     named in the joint account, be entitled to act on the instructions of any
     of them and shall not in any way whatsoever be liable to the others for
     doing so.


                                                           Page 245 of 258 Pages
<PAGE>
 
126. JOHIM has effected insurance to provide for the protection of the Client
     against losses arising from any negligence of JOHIM or any dishonesty of
     employees of JOHIM.

127. Under Section 54 of the Financial Services Act 1986 The Securities and
     Investments Board has established a scheme for compensating investors by
     which the Client may be entitled to compensation in the event of JOHIM's
     inability to meet any liabilities to the Client.  JOHIM will make available
     to the Client upon request a statement describing the Client's rights to
     compensation under the scheme.

DELEGATION AND USE OF AGENTS

128. JOHIM may delegate any of its functions under this Agreement to an
     Associate and may provide information about the Client and the portfolio to
     any such Associate but JOHIM's liability to the Client for all matters so
     delegated shall not be affected thereby.  JOHIM shall give to the Client
     written notice of any delegation of a function which involves the exercise
     of its discretionary investment management powers.

129. JOHIM may employ agents (including Associates) to perform any
     administrative, dealing, custodial and ancillary services required to
     enable JOHIM to perform its services under this Agreement.  JOHIM
     undertakes to act in good faith and with due diligence in the choice and
     use of such agents.

TERMINATION OF AGREEMENT

130. This Agreement may be terminated by either party by giving written notice
     of termination to the other at any time.  Termination shall take effect on
     the day upon which the other party actually receives the notice (the
     "Termination Date") provided that, where the Client is a joint account,
     notice of termination by JOHIM shall be given to every person named in the
     joint account and in such circumstances the Termination Date shall be
     deemed to be the day after the date of posting by first class recorded
     delivery or other appropriate means to all persons named in the joint
     account.

131. Upon the Termination Date, JOHIM will complete expeditiously all
     transactions in progress at termination but will not execute any further
     transactions for the Client. Upon all fees, commissions, expenses and other
     sums due to it and any other liabilities for which it may be or become
     liable in connection with the management of the Portfolio being settled or
     adequately secured to the satisfaction of JOHIM, JOHIM will ensure that all
     investments and cash balances held on the Client's behalf will, after any
     outstanding security registration, stock exchange settlements and other
     administrative matters have been completed as soon as reasonably
     practicable, be transferred to the Client or dealt with in accordance with
     the Client's instructions, in all cases at the cost of the Client.

132. Termination will not affect accrued rights, existing commitments or any
     contractual provision intended to survive termination and will be without
     penalty or other additional payment except that JOHIM may charge the Client
     an amount equal to:


                                                           Page 246 of 258 Pages
<PAGE>
 
     (a)  the relevant proportion of the management fee, corresponding to that
          part of the period ending on a valuation Date by reference to which
          fees are payable, which has expired when this Agreement is terminated;

     (b)  any additional expenses which JOHIM necessarily incurs in terminating
          this Agreement; and

     (c)  any losses necessarily realized in settling or concluding outstanding
          obligations.

133. The death, bankruptcy or other incapacity or, in the case of a body
     corporate, the cessation of business of the Client or a petition being
     presented or a meeting being convened to consider a resolution for the
     liquidation of the Client shall not of itself terminate JOHIM's
     appointment; but JOHIM may at its discretion treat its receipt of actual
     notice of any such events as if it were a written notice of termination
     from the Client.

134. If the Client is a joint account the Client's obligations under this
     Agreement shall be joint and several.  On the death of any of the persons
     constituting the Client (being survived by any such other person), the
     Agreement shall not terminate and, except in the case of trustees, the
     interest of the deceased in the Portfolio shall automatically inure to the
     benefit of the survivor(s) unless otherwise specified by notice in writing
     to JOHIM.

CLIENT WARRANTIES

135. The Client warrants that the Client is the beneficial owner (or the duly
     authorized agent of the beneficial owner) of the whole of the Portfolio
     free from all liens, charges, encumbrances and restrictions on transfer
     except insofar as advised by the Client to JOHIM, and will so remain during
     the currency of this Agreement.

136. The Client warrants that the Client is empowered to enter into this
     Agreement without the consent or authority of any other party and in the
     case of a Client being a body corporate the Client warrants that by
     entering into this Agreement it is not nor will it be in breach of its
     Memorandum or Articles of Association or any other relevant document.

GENERAL

137. Terms and expressions defined in the rules of IMRO for the time being in
     force shall where the context so admits bear the same meaning in this
     Agreement.

138. The Clause headings in this Agreement are included for ease of reference
     only and shall not affect its interpretation.

139. The Schedules to this Agreement are an integral part of it.

140. If the Client is an individual this Agreement shall be binding on his legal
     personal representatives.

141. This Agreement is personal to the parties hereto and shall not be capable
     of assignment.

142. Subject to clause 31, no change, alteration or modification to this
     Agreement or the Schedules hereto shall be made unless in writing and
     signed by the parties hereto.

143. Notice required or authorized to be served hereunder must be addressed to
     the address of the recipient stated above or to such other address as may

     Client from outside the United Kingdom and of notice serviced upon the
     Client to an address outside the United Kingdom, the notice shall be
     sufficiently served if served by prepaid letter, cable or telex.  In the
     case of notice served by the Client from within the United Kingdom and of
     notice served upon the Client to an address within the United Kingdom the
     notice shall be sufficiently served if served by prepaid letter.

144. If the Client makes a complaint to JOHIM verbally or in writing about any
     service JOHIM has rendered to the Client under this Agreement the complaint
     shall immediately be referred to JOHIM's Chief Executive or to a Senior
     Investment Manager who was not involved in the circumstances relating to
     the complaint and who will investigate such circumstances.  Upon the
     conclusion of his investigation he shall make a written report to the
     Client and take any action he deems necessary to rectify the matter which
     is the subject of the complaint.  The Client has the right to refer any
     complaint to IMRO if the Client is not satisfied with the action taken by
     the Chief Executive or Senior Investment Manager, and in any event has the
     right to make the complaint direct to IMRO or the Investment Ombudsman
     without prior reference to JOHIM.

145. Each party to this Agreement shall respect and protect the confidentiality
     of information acquired in consequence of it and shall not disclose such
     information to any third party save in the course of giving effect to this
     Agreement or as may be required by law, or where requested by regulatory
     authorities, or to their professional advisors where reasonably necessary
     for the performance of their professional services.

146. This Agreement is subject to English law and the parties hereto hereby
     submit to the jurisdiction of the English Courts in respect of it.

                 INVESTMENT POLICY, GUIDELINES AND RESTRICTIONS


                   PART I - Investment Policy including basis
                         of measurement of performance

The investment objectives are to maintain a maximum total return commensurate
with safety and the protection of the underlying value of the capital of the
fund.

The performance will be measured against the F.T. All Share Index, any other
appropriate Index or measure of performance agreed upon by JOHIM and the Client.


                     PART II - Guidelines and Restrictions

1.   There will be no restrictions placed on the types of investment in which
     the money comprised in the Portfolio will be invested provided that the
     services to be provided by JOHIM will not include advising on or effecting
     Contingent Liability Transactions, nor will they relate to options, futures
     or contracts for differences (or to any right or interest in such
     investments).

2.   The contents of the Portfolio may be advised in any market save for the
     following.

     There shall be no restriction on the amount of monies or proportion of the
     Portfolio invested in any one investment or type of investment permitted
     hereunder provided that, subject to the provisions relating to overdraft
     contained in paragraph 6 of this Agreement, under no circumstances will
     JOHIM make investments on behalf of the Client to a value in excess of the
     aggregate of the value of the funds and securities held by JOHIM on behalf
     of the Client in the accounts referred to in paragraph 16 of this
     Agreement.


             PART III - Risk Warnings and Risk Disclosure Statement

                 Investments Denominated in Foreign Currencies

If a liability of the Client in one currency is to be matched by an asset in a
different currency, or if JOHIM provides services under this Agreement relating
to an investment denominated in a foreign currency, a movement in exchange rates
may have an effect which may be either favorable or unfavorable on the
investment, which effect may be separate from the gain or loss otherwise
experienced on such investment.

                       Investments not readily realisable

Certain categories of investments comprised in the Portfolio may not be readily
realizable. You should be aware that there can be no certainty that market
makers or brokers will be 


                                                           Page 249 of 258 Pages
<PAGE>
 
prepared to deal in such investments and that proper information for determining
their current value may not be available.

                                    Warrants

A warrant is a right to subscribe for shares, debentures, loan stock or
government securities, and is exercisable against the original issuer of the
securities.  Warrants often involve a high degree of gearing so that a
relatively small movement in the price of the underlying security results in a
disproportionately large movement, unfavorable as well as favorable, in the
price of the warrant.  The prices of warrants can therefore be volatile.

                                 Stabilisation

This statement is made in compliance with Rule 14 of Chapter IV of the rules of
IMRO.

"We or our representatives may from time to time effect on your behalf or
recommend to you transactions in securities which are the subject of a recent
new issue where the price of those transactions may have been influenced by bids
made or transactions effected for the purpose of stabilizing the price of those
securities.  You should read the explanation below carefully.  Its purpose is to
enable you to judge whether you wish your funds to be invested at all in such
securities or, if so, whether you wish to authorize us generally to effect
transactions in such securities on your behalf without further reference to you
or whether you wish to be consulted before any particular transaction is
effected on your behalf.

Stabilisation is a process whereby the market price of a security is pegged or
fixed during the period in which a new issue of securities is sold to the
public.  Stabilisation may take place in the new issue or in other securities
related to the new issue in such a way that the price of the other securities
may affect the price of the new issue or vice versa.

The reason stabilisation is permitted is that when a new issue is brought to
market the sudden glut will sometimes force the price lower for a period of time
before buyers are found for the securities on offer.

As long as he obeys a strict set of rules the "stabilizing manager", normally
the issuing house chiefly responsible for bringing a new issue to market, is
entitled to buy securities in the market that he has previously sold to
investors or allotted to institutions who were included in the new issue but who
have decided not to continue participating.  The effect of this may be to keep
the price at a higher level than would otherwise be the case during the period
of stabilizing.

The rules limit the period in which he may stabilize, fix the price at which he
may stabilise (in the case of shares and warrants but not bonds), and require
him to disclose that he may be (but not that he is) stabilising.

The fact that a new issue or a related security is being stabilised does not in
itself mean that investors are not interested in the issue, but neither should
the existence of transactions in an issue where stabilising may take place be
relied upon as an indication that investors are

interested in the new issue or interested in purchasing at the price at which
transactions are taking place".
