Item 2.  Acquisition or Disposition of Assets.

         On January 4,  1999,  Iron  Mountain  Incorporated  ("Iron  Mountain"),
through a wholly owned  subsidiary,  purchased a majority  interest in Britannia
Data  Management  Limited,  a  corporation  formed under the laws of England and
Wales  ("BDM"),  from Mentmore  Abbey plc pursuant to an Agreement,  dated as of
December 2, 1998,  between Iron Mountain and Mentmore Abbey plc. The acquisition
will be accounted for as a purchase and BDM will be included in Iron  Mountain's
consolidated financial results from the date of acquisition.

         Consideration  for the 50.1 percent  interest in BDM was $47.7  million
and was comprised of cash and the capital  stock of Arcus Data Security  Limited
("ADS"),  Iron Mountain's  existing data security business in London.  The funds
used for the  consideration  were comprised of borrowings  under Iron Mountain's
$250 million  revolving credit  facility,  dated September 27, 1997, as amended,
among Iron Mountain,  various  financial  institutions  and The Chase  Manhattan
Bank, as administrative agent for such lenders.

         The assets acquired by Iron Mountain  included real property,  tangible
personal  property  (consisting  primarily of office  equipment,  furniture  and
fixtures, motor vehicles, racking and shelving) and intangible personal property
regularly used in BDM's records  management  business.  Iron Mountain intends to
use  the  acquired  property  and  equipment  in the  operation  of its  records
management business in the United Kingdom.

Abbey and BDM and their  respective  Subsidiaries;  they comply in all  material
respects  with  applicable  accounting  requirements,   have  been  prepared  in
accordance  with U.K.  GAAP  applied on a  consistent  basis  during the periods

the consolidated  financial position, and the consolidated results of operations
and cash flows (and changes in financial position, if any), of Britannia and BDM
and their respective  Subsidiaries  and the ARM Assets,  as of the times and for
the periods referred to therein.

                  Section 4.13 Books and Records.  To the Knowledge of Mentmore,
the books of account,  minute  books and share  register of Abbey (as relates to
the ARM Assets),  and Britannia and BDM and their respective  Subsidiaries,  are
complete  and  correct in all  material  respects  and have been  maintained  in
accordance with sound business practices.  The minute books of Abbey (as relates
to the ARM Assets), and Britannia and BDM and their respective  Subsidiaries (as
at the date of this  Agreement),  contain  accurate and complete  records of all
meetings held since October 8, 1996 of, and corporate action taken since October
8,  1996  by,  their  respective  shareholders,  and no  meeting  of any of such
shareholders has been held since October 8, 1996 for which minutes have not been
prepared and are not contained in such minute books.

                  Section  4.14  No  Undisclosed  Liabilities.   Except  (i)  as
disclosed in the Mentmore  Disclosure Letter,  (ii) as disclosed in the Combined
Financial  Statements,  or (iii) for liabilities and obligations incurred in the
ordinary course of business and consistent with past practice since the Combined
Balance  Sheet  Date,  neither  Britannia  nor BDM nor any of  their  respective
Subsidiaries  has any  liabilities or obligations of any nature,  whether or not
accrued,  contingent  or  otherwise.  The  reserves  reflected  in the  Combined
Financial  Statements  are adequate,  appropriate  and  reasonable and have been
calculated in a consistent manner with prior periods.

                  Section 4.15 Accounts  Receivable.  All accounts receivable of
Abbey (as relates to the ARM Assets),  and  Britannia  and BDM and each of their
respective  Subsidiaries,  reflected in the Combined  Balance  Sheet,  represent
sales  actually  made in the ordinary  course of  business,  and are current and
collectible net of any reserves shown on the Combined Balance Sheet.

                  Section 4.16 Interim  Operations.  Since the Combined  Balance
Sheet Date, the business of Abbey (as relates to the ARM Assets),  and Britannia
and BDM and each of their  respective  Subsidiaries,  has been conducted only in
the ordinary and usual course consistent with past practice.  Since the Combined
Balance  Sheet Date,  there have not been any  material  adverse  changes in the
financial condition, assets or results of operations of Abbey (as relates to the
ARM Assets), or Britannia or BDM or any of their respective Subsidiaries.  Since
the Combined  Balance Sheet Date,  such assets have not been affected in any way
as a result of flood, fire,  explosion or other casualty (whether or not covered
by insurance). To the best Knowledge of Mentmore, there is no circumstance which
is likely to cause Abbey (as relates to the ARM Assets), Britannia or BDM or any
of their respective  Subsidiaries,  to suffer any material adverse change in its
business, operations or prospects.

                  Section 4.17 Absence of Certain  Changes.  Except as set forth
in the Mentmore Disclosure Letter,  since the Combined Balance Sheet Date, Abbey
(as  relates  to the ARM  Assets),  and  Britannia  and BDM  and  each of  their

leasehold  estate  created  by  each  Arcus  Lease  is  free  and  clear  of all
Encumbrances.  There are no  existing  defaults  by Arcus under any of the Arcus
Leases.  No event has occurred that (whether  with or without  notice,  lapse of
time or the  happening or  occurrence  of any other  event)  would  constitute a
default under any Arcus Lease, including (by way of example only) the failure by
the lessee to perform all maintenance or repairs required to be performed by the

Property rights or any other proprietary right of any Person,  and Arcus has not
received any written  notice from any other Person  pertaining to or challenging

by the Abbey (as relates to the ARM Assets),  or Arcus,  Britannia or BDM or any
of their respective Subsidiaries,  or terminate or modify the terms of any lease
or other  contract  to which  Abbey (as  relates to the ARM  Assets),  or Arcus,

the provisions of Section 9.2(c)(iii) above) be liable for damages under Section

                           (d) IM's right to claim damages under Section  9.2(a)

                  Section 9.4 IM Notice of Third-Party Claim;  Defense. IM shall
give Mentmore prompt notice of any  third-party  claim that may give rise to any
claim by IM under this Article IX,  together with the  estimated  amount of such
claim,  and Mentmore  shall have the right to assume the defense (at  Mentmore's
expense) of any such claim  through  counsel of  Mentmore's  own  choosing by so
notifying IM within 30 days of the first receipt by Mentmore of such notice from
IM; provided, however, that any such counsel shall be reasonably satisfactory to
IM.  Failure  to  give  prompt  notice  shall  not  affect  the  indemnification
obligations hereunder in the absence of actual and material prejudice. If, under
applicable  standards of  professional  conduct,  a conflict with respect to any
significant  issue between IM and Mentmore exists in respect of such third-party
claim,  Mentmore shall pay the reasonable  fees and expenses of such  additional
counsel as may be required to be  retained  in order to resolve  such  conflict.
Mentmore shall be liable for the fees and expenses of counsel employed by IM for
any  period  during  which  Mentmore  does not  assume  the  defense of any such
third-party  claim (other than during any period in which IM will have failed to
give notice of the third-party  claim as provided  above).  If Mentmore  assumes
such defense,  IM shall have the right to participate in the defense thereof and
to employ  counsel,  at its own expense,  separate from the counsel  employed by
Mentmore,  it being  understood  that Mentmore  shall  control such defense.  If
Mentmore chooses to defend or prosecute a third-party  claim, IM shall cooperate
in the defense or  prosecution  thereof,  which  cooperation  shall  include the
retention,  and the provision to Mentmore, of records and information reasonably
relevant to such  third-party  claim, and making employees of BDM available on a
mutually  convenient basis to provide additional  information and explanation of
any materials provided hereunder.  If Mentmore elects to defend or prosecute any
third-party claim, IM shall agree to any settlement,  compromise or discharge of
such  third-party  claim that  Mentmore may  recommend  and that,  by its terms,
discharges  IM and IM  Indemnified  Persons from the full amount of liability in
connection with such third-party  claim;  provided,  however,  that, without the
consent of IM,  Mentmore  shall not  consent to, and IM shall not be required to
agree to,  the  entry of any  judgment  or enter  into any  settlement  that (i)
provides for  injunctive  or other  non-monetary  relief  affecting IM or any IM
Indemnified  Person,  or (ii) does not include as an unconditional  term thereof
the giving of a release  from all  liability  with respect to such claim by each
claimant or  plaintiff  to each of IM or any IM  Indemnified  Person that is the
subject of such third-party claim.

                  Section 9.5  Mentmore Indemnification.

                           (a) IM shall  indemnify,  defend  and  hold  harmless

Persons  from and against  and in respect of 100% of any and all actual  losses,
liabilities,  damages,  judgments,  settlements and expenses (including interest
and  penalties  recovered by a third party with respect  thereto and  reasonable
attorneys'  fees and  expenses  and  reasonable  accountants'  fees and expenses
incurred  in the  investigation  or defense of any of the same or in  asserting,
preserving or enforcing any of the rights of Mentmore arising under this Article
IX) incurred by Mentmore or any of the Mentmore Indemnified Persons,  that arise

and warranties contained in Sections 5.1, 5.2, 5.3, 5.4, and 5.7; or

representations and warranties contained in Section 5.27 or the existence of any
of the events,  circumstances or conditions described in Section 5.27 hereof, or
any pollution or threat to human health or the  environment  that (X) is related
in any way to Arcus's (or any other  owner's or  operator's),  management,  use,
control,  ownership or operation of the  properties or businesses of Arcus prior
to the Closing  Date,  including all on-site and off-site  activities  involving
Materials of Environmental Concern, and (Y) occurred,  existed, or arises out of
conditions or circumstances that occurred or existed, or was caused, in whole or
in part, on or before the Closing  Date,  whether or not the pollution or threat
to human health or the environment is described in the IM Disclosure Letter, and
(B) any  Environmental  Claim  against  Arcus has  assumed  or  retained  either
contractually  or by operation  of law  (collectively,  "Mentmore  Environmental
Losses"); provided, however, that the term "Mentmore Environmental Losses" shall
not include any such losses,  liabilities,  damages,  judgments,  settlements or
expenses incurred as a result of (m) any action taken by Arcus after the Closing
Date  which,  at the time such action was taken,  Arcus knew such  action  could
result in a Mentmore  Environmental Loss, or (n) any change in Environmental Law
occurring after the Closing Date.

                           (b) IM's  indemnification  obligations  arising under
Section  9.5(a)(i)  shall  survive  forever;  IM's  indemnification  obligations
relating to Mentmore Environmental Losses arising under Section 9.5(a)(ii) shall
survive until January 4, 2009.

                           (c) No claim for a recovery  under Section 9.5 may be
asserted  by  Mentmore in its  individual  capacity  or as trustee for  Mentmore
Indemnified  Persons  after the  expiration  of the  applicable  indemnification
period set forth in Section 9.5(b) above;  provided,  however, that claims first
asserted  in writing by Mentmore  in its  individual  capacity or as trustee for
Mentmore Indemnified Persons with reasonable specificity prior to the expiration
of the applicable  indemnification  period shall not thereafter be barred by the
expiration of the applicable indemnifica tion period.

                           (a) Mentmore  shall be entitled to claim damages from
IM in respect of 49.9% of any and all losses,  liabilities,  damages, judgments,

party with respect thereto and reasonable  attorneys' fees and expenses incurred
in the  investigation or defense of any of the same or in asserting,  preserving
or  enforcing  any of the rights of  Mentmore  arising  under this  Article  IX)

covenants contained in this Agreement;

                                   (i) any civil,  criminal,  administrative  or
arbitration  proceeding or  investigation by or before any court or governmental
or other regulatory or administrative  agency or commission against or involving
Arcus or relating to Arcus with respect to all periods prior to the date of this
Agreement; or

provisions  of Section  9.6(c)(iii)  above) be liable for damages  under Section

<PAGE>


Mentmore within 30 days of the first receipt by IM of such notice from Mentmore;

IM elects to defend or prosecute any third-party claim,  Mentmore shall agree to
any settlement,  compromise or discharge of such  third-party  claim that IM may
recommend and that, by its terms,  discharges  Mentmore and Mentmore  Affiliates
from the full amount of liability in  connection  with such  third-party  claim;
provided,  however,  that, without the consent of Mentmore, IM shall not consent
to, and Mentmore shall not be required to agree to, the entry of any judgment or
enter into any settlement that (i) provides for injunctive or other non monetary
relief affecting Mentmore or any Affiliate of Mentmore, or (ii) does not include
as an unconditional term thereof the giving of a release from all liability with
respect to such claim by each  claimant or  plaintiff to each of Mentmore or any
Affiliates of Mentmore that is the subject of such third-party claim.

                  Section 9.9  Procedure.  (a) IM shall provide  Mentmore with a

                  Section 9.11  Survival of Remedies.  The remedies set forth in
this  Article IX shall  survive  the  Closing  and shall  survive  the  proposed
transfer of the business and assets  (subject to the  liabilities))  of Arcus to
BDM after the Closing);  provided,  however,  that if there is an agreed sale of
BDM pursuant to the Strategic Alliance Agreement,  these remedies will terminate
and be of no further force or effect.

indemnity  payments made pursuant to this Agreement shall be treated for all Tax
purposes as adjustments to the consideration paid with respect to the Shares.

indemnification,  or  other  remedies  based  on any  representation,  warranty,
covenant or  obligation  contained in this  Agreement  or the Closing  Documents

knowledge acquired (or capable of being acquired) at any time, whether before or
after the  execution  and  delivery  of this  Agreement  or the date the Closing
occurs,  with respect to the accuracy or inaccuracy of or compliance  with,  any
such representation,  warranty,  covenant or obligation. The waiver by any party
of any condition to the obligation to consummate the  Transactions  contemplated
by this  Agreement,  where  such  condition  is  based  on the  accuracy  of any
representation  or warranty,  or on the  performance  of or compliance  with any
covenant  or   obligation,   shall  not  affect  the  right  by  such  party  to
indemnification,  or  other  remedy  based  on  such  representation,  warranty,
covenant or obligation.

                  Section 9.14 Duty to Mitigate. Nothing herein shall in any way

Britannia),  any  capital  requirements  of  Britannia,  BDM  or  any  of  their
respective  Subsidiaries,  arising solely out of actual monetary losses, damages
or  expenses   incurred  by  Britannia  or  BDM  (or  any  of  their  respective
Subsidiaries),  for which  payments are required to be made  pursuant to Section

not be  required to fund such  capital  requirements  (referred  to in the prior
sentence. In an amount which exceeds the payment it received pursuant to Section

against the party resisting such enforcement.

                           (f) This Agreement and the rights and  obligations of

contained in this  Agreement.  Any  agreement on the part of a party to any such

signed on behalf of such party.  The failure of any party to this  

                                    Page 63

Agreement  to assert any of its rights under this  Agreement or otherwise  shall
not constitute a waiver of those rights.

Party and  (iii)  permitting  Britannia  to decide  whether  or not the  Related
Transaction  is to be effected  by  Britannia  (the right to make such  decision
being a "Right of First Refusal").  The Chairman shall convene a Special Meeting
(a "Related Transaction  Meeting") within ten (10) Business Days of the date the
Chairman is informed of the  Related  Transaction.  The notice for such  Special
Meeting shall contain a reasonably  detailed summary of the Related  Transaction
as  communicated  to the  Chairman.  The  Shareholders  and the Parent  (and any
Subsidiary of either  Shareholder or the Parent other than  Britannia)  shall be
prohibited  from pursuing the Related  Transaction in any manner,  or taking any
action in connection  therewith,  until the  Britannia  Board shall have decided
whether or not to exercise its Right of First  Refusal,  which  decision must be
made within ten (10) days of the date of the Related Transaction Meeting. In the
event the Britannia Board decides such Related  Transaction is to be effected by
Britannia,  the  Shareholders  and the  Parent  (and any  Subsidiary  of  either
Shareholder or the Parent other than Britannia) shall be prohib ited from taking
any action  (other than  pursuant to this  Agreement  or to further the business
aims of, or to provide  assistance  to,  Britannia)  in respect of such  Related
Transaction  and  Britannia  shall be the  Parties'  (and  their  Subsidiaries')
exclusive channel for negotiating and effecting the Related  Transaction and for
the marketing and development of the Records Management  Business in the Related
Transaction  Market.  In the event the Britannia  Board decides that the Related
Transaction will not be effected by Britannia, a Shareholder that has caused its
representative(s)  on the Britannia Board to vote in favor of Britannia pursuing
the  Related  Transaction  (or any  Affiliate  of such  Shareholder  other  than
Britannia)  will  thereafter be free to effect the Related  Transaction on terms
that are not materially more favorable to such  Shareholder  than those on which
the Related  Transaction  was acted upon by the Britannia  Board. In such event,
(i) neither Britannia, nor the other Shareholder,  nor (if the other Shareholder
is IM) the Parent (nor any of their respective  Subsidiaries) shall individually
or jointly with any other Person  effect such  Related  Transaction,  enter into
discussions or negotiations with any Person relating thereto, provide technology
or  financial  assistance  to any Person in  connection  therewith  and (ii) the
Shareholder  effecting  the  Related  Transaction  (or  any  Affiliate  of  such
Shareholder  other than Britannia)  shall thereafter have the exclusive right to
discuss,  negotiate  or effect any  transaction  in or  related  to the  Records
Management Business in the Related Transaction Market; provided,  however, that,
if, after the Britannia Board has voted to cause Britannia to exercise its Right
of First  Refusal  or has  permitted  a  Shareholder  (or an  Affiliate  of such
Shareholder)  to  pursue  the  Related  Transaction,  either  Britannia  or  the
Shareholder  (or  an  Affiliate  of  such  Shareholder)   pursuing  the  Related
Transaction,  as the case may be,  does not enter  into a  definitive  agreement
relating to the Related Transaction

                                       12

within ninety (90) days of the Related  Transac tion Meeting and  consummate the
transaction  within sixty (60) days of entering into such definitive  agreement,
Britannia or such  Shareholder (or the relevant  Affiliate of such  Shareholder)
shall be deemed to have  abandoned the Related  Transaction  and shall  promptly
notify  the  other  Shareholder  or  Shareholders,  as the case  may be,  of its
decision to abandon the Related  Transaction (an  "Abandonment").  Following any
Abandonment,  neither  Shareholder  nor the Parent (nor any of their  respective
Subsidiaries other than Britannia) shall pursue any Related  Transactions in the
Related  Transaction  Market without  following the procedures set forth in this
Section 2.4(b).

                  (c) Any Breach of any  provision of this  Section  2.4,  other
than  with the  consent  of a  Nonbreaching  Shareholder  (as  defined  herein),
notwithstanding  any  declaration  of  invalidity  with  respect  thereto by any
competent governmental,  judicial or administrative authority, shall be deemed a
Breach of this Agreement entitling the Nonbreaching  Shareholder to the remedies
set forth in Article VII hereof.

                  (d) The  provisions  of this  Section 2.4 shall only remain in
effect for so long as this Agreement remains in effect.

                  2.5  Service Agreements; Other Agreements.

                  (a)  In  order  to  assist   Britannia  in  carrying  out  its
objectives as set forth in this Agreement,  the  Shareholders (or an appropriate
Affiliate  thereof) shall provide  Britannia  with, and Britannia shall pay for,
such support and assistance as Britannia reasonably require from time to time at
the fully-burdened  cost of the Shareholder or Affiliate  providing such support
and assistance.

                  (b) Subject to the provisions of Section 5.10(l)  hereof,  the
Sharehold ers expressly  agree and  acknowledge  that  customer  contract  terms
(including  pricing  terms)  of  Britannia  shall be  governed  by local  market
standards and shall not necessarily be subject to global contract conditions.

                  3.1  Declaration  of Dividends.  Subject to Section 7.2 hereof
and unless (i) prohibited by applicable law or any agreement to which  Britannia
is, or may become,  subject,  or (ii) the Board specifies  otherwise,  Britannia
shall distribute  annually to the Shareholders 100% of all amounts available for
distribution as Ordinary Dividends.

                            CAPITALIZATION; FINANCING

                  4.1 Debt  Financing.  The  Shareholders  hereby agree that any
expan sion or development of the Records Management  Business,  including by way
of acquisition or capital investment, shall be funded principally by Britannia's
incur rence of debt.

                  4.2 Equity Financing.  Each of the Shareholders  will, subject
to  applicable  UK law,  be required to invest  additional  equity,  beyond such
amounts as are contemplated in the Transaction Agreement and in such a manner as
will preserve the relative percentage shareholdings of each Shareholder upon the
comple tion of the transactions contemplated in the Transaction Agreement, up to
a cumula tive maximum per Shareholder of three million pounds ((pound)3,000,000)
(the  "Equity  Cap"),  in the  manner  and on the  time  schedule  set  forth in
Britannia's  Budget.  Subject to the  provisions  of such  Budget and subject to
Sections 4.3 and 7.2(b) below, each of the Shareholders will also be entitled to
invest additional equity in Britannia;  provided,  however,  that neither IM nor
Mentmore  nor any of their  Affiliates  shall  have any  obligation  to make any
equity investments in Britannia above the Equity Cap.

                  4.3 Budget.  Subject to Section 5.10 hereof,  Britannia  shall
prepare a budget  (the  "Budget")  on at least an  annual  basis  setting  forth
Britannia's  anticipated capital requirements and the amounts of such capital to
be  raised  as  debt  and  equity,   respectively,   together  with  Britannia's
anticipated  revenues  and  expenses,  its  targeted  new sales volume and other
operational  forecasts or  objectives.  Such Budget  shall  indicate the capital
intended to be raised  from the  Shareholders  and other  sources as well as the
timing  of  any  required  capital   contributions  by  the  Shareholders.   The
Shareholders  expressly agree that they shall not be obligated to contribute any
amounts to Britannia in the form of debt and that they shall not be obligated to
make any equity  investments  beyond the Equity Cap.  The  Shareholders  further
agree that any adjustment in the  Shareholders'  percentage  equity ownership of
Britannia   shall  

                                       14
<PAGE>

be subject to the unanimous approval of Britannia's Shareholders;  provided, how
ever,  that in the event  that any  Shareholder's  percentage  ownership  of the
Shares of Britannia  falls to or below twenty  percent (20%),  such  Shareholder
shall be deemed to be a  Withdrawing  Shareholder  pursuant to Section 7.6 below
and the other Shareholder shall be deemed a Nonwithdrawing  Shareholder pursuant
to such Section;  provided,  further, such deemed Nonwithdrawing Shareholder may
initiate  the  procedures  set forth in such  Section 7.6 by providing a Buy-Out
Notice to the deemed  Withdrawing  Shareholder and Britannia  within thirty (30)
days of the date such deemed Withdrawing  Shareholder's  percentage ownership of
the Shares of Britannia  falls to or below twenty percent  (20%);  and provided,
further,  the deemed  Nonwithdrawing  Shareholder  may  thereafter  purchase the
deemed Withdrawing  Shareholder's Shares in accordance with Sections 7.6 and 7.7
below.

                  4.4  Pledge  of  Shares.  In  addition  to  the  Shareholders'
obligation to provide equity investments up to the amount of the Equity Cap, the
Shareholders agree to pledge their Shares to Britannia's creditors to the extent
necessary  to obtain  the funds  identified  in  Britannia's  Budget;  provided,
however,  that  it  shall  not be a  breach  of  this  Section  4.4  for  either
Shareholder to fail to pledge its Shares to Britannia's creditors if such Shares
have previously  been pledged,  mortgaged,  assigned or otherwise  encumbered to
such Shareholder's  creditors. To the extent that Britannia's financing needs do
not  require  any  pledge of Shares at such time as either  Shareholder  (at its
discretion) desires to pledge, mortgage, assign or otherwise encumber its Shares
to its creditors,  each Shareholder shall be free to pledge, mortgage, assign or
otherwise  encumber its stock to banks or other financial institu tions. Save as
provided in this Section 4.4,  any failure of the  Shareholders  to pledge their
stock or any pledge of stock that is  inconsistent  with the  provisions of this
Section  4.4  shall be  deemed a Breach of this  Agreement  and  shall  give the
Nonbreaching Shareholder the rights set forth in Article VII hereof.

Mentmore or any Affiliate  thereof (other than Britannia).  The Parties agree to
take all action  necessary  to ensure  that the members of the  Britannia  Board

the  Chairman  shall have the right to adjourn such meeting for a period of time
designated by the Chairman, but not exceeding thirty (30) days.

                  5.8 Unanimous  Written  Consent.  Notwithstanding  anything in

if any  Shareholder  fails to pay in full any  contribution  to the  capital  of
Britannia  pursuant to this  Agreement,  the Articles,  or the Budget (each such
Shareholder  being  a  "Defaulting  Shareholder"),   such  failure  (a  "Payment
Default")  shall  constitute  a  Breach  of this  Agreement  by such  Defaulting
Shareholder.  A Payment  Default shall be deemed to have occurred on the date on

Business  Days of having  been  informed  of the  Payment  Default,  send notice
thereof to the Shareholders (such notice being a "Default Notice").

                  6.2 Cure of Payment Default. A Payment Default shall be deemed
to have been cured when (and only when) the full amount of the Payment  Default,
plus  interest  thereon at the  Default  Rate (as in effect  from time to time),
accruing from the date of the Payment  Default until the date of cure,  has been
paid by the curing Defaulting Shareholder.

capital, the creation of any new class of shares or the alteration or abrogation
of the rights  attaching to any class of shares in Britannia's  authorized share
capital,  issuance  of any new shares in  Britannia,  any  issuance of shares or
other  equity  interests   (whether  such  issuance  alters  or  may  alter  the
Shareholders'  percentage  equity  ownership in Britannia or  otherwise)  or any
requirement for the Shareholders to contribute  additional  capital to Britannia
beyond the Equity Cap;

                  (c) all  repurchases  of shares (of  whatever  class) or other

adminis  tration  order in respect of Britannia or any  Subsidiary of Britannia;
and

                  (f) the declaration of Ordinary Dividends.

                  7.3 Breach or Violation. (a) Subject to Section 2.1(b), if any
Shareholder or the Parent (such Shareholder, or if the Parent, the Parent and IM
collectively,  being referred to as a "Breaching  Shareholder")  is in breach of
any Material  obligation under this Agreement  (including,  without  limitation,
through any (i) violation of any Material  provision of the  Articles,  (ii) any
failure  to vote (or cause to be voted)  its  Shares in  Britannia  pursuant  to
Sections  7.1 or 7.2 above,  or take (or cause to be taken) any other  action in
respect of Britannia as required under this Agreement,  notwithstanding that the
action  taken or  omitted  may be valid and lawful  when  judged  under  another
instrument  (including  the  Articles),  when taken in  isolation or under a law
other than the law chosen in Section 9.1, (iii) any Payment  Default or (iv) any
inability or failure to perform its Material obligations  hereunder or under any
Exhibit hereto or to take (or cause to be taken) actions  generally  required to
be taken hereunder or under any Exhibit hereto (any of (i), (ii),  (iii) or (iv)
being  a  "Breach"),  then  the  non-breaching  Shareholder  (the  "Nonbreaching
Shareholder")  may give  written  notice  of such  Breach or  violation  to such
Breaching Shareholder (with a simultaneous copy to Britannia) (such notice being
a "Breach  Notice").  If such breach or violation  continues  unremedied  for at
least  thirty  (30)  days  after  delivery  of  the  Breach  Notice,   then  the
Nonbreaching  Shareholder  may give written notice to the Breaching  Shareholder
(with a  simultaneous  copy to Britannia) of activation of buy-out  rights under
Section  7.6(a)  below  with  respect  to the  Shares  owned  by such  Breaching
Shareholder (such notice being a "Breach Buy- Out Notice").

                                       22

                  (b) A Breaching Shareholder may cure any breach giving rise to
a Breach  Buy-Out  Notice (i) by ceasing any action  prohibited  by the terms of
this Agreement or by taking any action required to be taken  hereunder,  (ii) in
the case of a Payment  Default,  by making all  payments  required  pursuant  to
Section 6.2 and (iii) by reimbursing the Nonbreaching  Shareholder and Britannia
for any and all reason able,  out-of-pocket  expenses and costs  (including  all
reasonable legal costs) incurred by the  Nonbreaching  Shareholder and Britannia
as a result of the breach of any Material obligation hereunder.

                  7.4 Bankruptcy. (a) If any Shareholder or the Parent shall:

                           (i) have  commenced  a  receivership,  bankruptcy  or
         insolvency  proceeding,  or commenced or convened a meeting to consider
         dissolution,  liquidation,  administration  or (if  applicable)  made a
         proposal  for a voluntary  arrangement  or proposed or entered into any
         other  arrangement  or  composi  tion  with and to the  benefit  of its
         creditors  generally  or  commenced,  made or proposed  any  proceeding
         analogous to the foregoing;

                           (ii) had commenced against it such a proceeding,  and
         such  proceeding  has  resulted in the entry of an order  against  such
         Shareholder  which shall not have been vacated,  discharged,  stayed or
         bonded  pending  appeal within thirty (30) days from the entry thereof;
         or

                           (iii) be bankrupt or insolvent,  or generally  unable
         to pay its debts as they become due;

(any such Shareholder,  or if the Parent, the Parent and IM collectively,  being
referred  to as a  "Bankrupt  Shareholder"),  then the  other  Shareholder  (the
"Nonbankrupt  Shareholder") may immediately give written notice to such Bankrupt
Shareholder  (with a simultaneous  copy to Britannia),  of activation of buy-out
rights  under  Section  7.6(a)  with  respect  to the  Shares  of such  Bankrupt
Shareholder (such notice being a "Bankruptcy Buy-Out Notice").

                  (b) A Bankrupt  Shareholder may cure any situation giving rise
to a Bankruptcy  Buy-Out Notice (i) by  definitively  terminating any proceeding
referred to in Section 7.4(a)(i), or obtaining the vacation,  discharge, stay or
bonding pending appeal of the order for relief referred to in Section 7.4(a)(ii)
and (ii)  reimbursing the Nonbankrupt  Shareholder and Britannia for any and all
reasonable,  out-of-pocket  expenses and costs  (including all reasonable  legal
costs) incurred by the Nonbankrupt  Shareholder and Britannia as a result of the
situation giving rise to the Bankruptcy Buy-out Notice.

                                       23
<PAGE>

                  7.5 Change of Control.  (a) If a Change of Control occurs with
respect to any  Shareholder or the Parent (such  Shareholder  or, if the Parent,
the Parent and IM collectively,  being a "Change of Control  Shareholder")  then
the other Shareholder (the "Non-Change of Control  Shareholder") may immediately
give written  notice to the Change of Control  Shareholder  with a  simultaneous
copy to Britannia) of  activation  of buy-out  rights under Section  7.6(a) with
respect to the Shares of such Change of Control Shareholder (such notice being a
"Change of Control Buy-Out Notice").

                  (b) A Change of  Control  Shareholder  may cure the  situation
giving  rise to the  Change  of  Control  Buy-Out  Notice by (i)  obtaining  the
rescission of any  agreement or contract  giving rise to a Change of Control and
(ii) reimbursing the Non-Change of Control Shareholder and Britannia for any and
all reasonable, out-of-pocket expenses and costs (including all reasonable legal
costs) incurred by the Non-Change of Control  Shareholder and Britannia incurred
as a as a result of the situation  giving rise to the Change of Control  Buy-Out
Notice.

                  7.6 Share  Acquisition  in the Event of Breach,  Bankruptcy or
Change of Control.  (a) Upon delivery of a Buy-Out  Notice,  the  Nonwithdrawing
Share  holder  shall  have an  irrevocable  (except  to the  extent set forth in
paragraph (b) below) and exclusive option,  but not the obligation,  to purchase
all (but not less than all) of the Shares owned by the Withdrawing  Shareholder;
provided,  however,  that the  Withdrawing  Shareholder  may at any time  within
fourteen (14) days of delivery of a Buy-Out Notice invoke the  conciliation  and
arbitration provisions of Article IX hereof. If (i) the Withdrawing  Shareholder
fails both to cure the situation giving rise to the Buy-Out Notice and to invoke
such  conciliation  and  arbitration  provisions  within  fourteen  (14) days of
delivery of a Buy-Out Notice or (ii) the Conciliation  Committee or the arbitral
tribunal acting pursuant to Article IX hereof  concludes that the Buy-Out Notice
was appropriately delivered to the Withdrawing  Shareholder,  the Nonwithdrawing
Shareholder  may, at its option,  at the  expiration  of such  fourteen (14) day
period or upon notification of the final decision of the Conciliation Com mittee
or the arbitral  tribunal (X) waive its rights  hereunder and elect to leave the
Shareholders'  relative  shareholdings  in Britannia  unaffected by the event or
situation giving rise to the Buy-Out Notice, (Y) activate its option to purchase
the Withdraw ing  Shareholder's  Shares by delivery of notice to the Withdrawing
Shareholder  and  Britannia  (the  "Option  Exercise  Notice")  or (Z) declare a
Deadlock  and trigger  the  withdrawal  and sale  provisions  of Section  7.8(b)
hereof; provided, however, that in the event the delivery of the Option Exercise
Notice or the  declaration of a Deadlock  pursuant to the foregoing  sub-clauses
(Y) or (Z) is the  result of a Breach,  all deci  sions of the  Britannia  Board
shall  be  taken  solely  by  the  directors  appointed  by  the  Nonwithdrawing
Shareholder  and the  presence of the  directors  appointed  by the  Withdrawing
Shareholder  shall not be required  for any quorum  pursuant to Section 5.7. The
price of the shares to be  purchased  pursuant  to such  option  shall be agreed
among the Shareholders through discussions between the

                                       24
<PAGE>

Shareholders'  respective chief executive officers, or, if such agreement cannot
be reached  within  thirty  (30) days of the  delivery  of the  Option  Exercise
Notice,  pursuant to a valuation of such Shares by an independent  merchant bank
(or other third party) (the "Buy-Out Appraiser"). The Buy-Out Appraiser shall be
designated jointly by the Shareholders or, in the event the Shareholders  cannot
agree  on  such  Buy-Out   Appraiser  within  twenty  (20)  days  (the  "Initial
Designation Period") of the conclusion of the twenty (20) day negotiation period
described  above,  by an  independent  merchant  bank  (or  other  third  party)
designated by two  independent  merchant banks (one of which shall be designated
by one of the  Shareholders  and the other of which shall be  designated  by the
other  Shareholder)  within  twenty (20) days of the  conclusion  of the Initial
Designation  Period.  Within thirty (30) days of being selected,  the Buy-Out Ap
praiser  shall  determine  the price  (the  "Buy-Out  Price")  to be paid to the
Withdrawing  Shareholder  for its  Shares  on the  basis  of such  Shareholder's
proportionate  interest in the going  concern value of Britannia  (i.e.,  at the
price at which a willing  buyer and a willing  seller,  neither  being under any
compulsion  to buy or sell and both  having  reasonable  knowledge  of  relevant
facts,  would agree to buy and sell the Shares of Britannia  for cash,  free and
clear of all liens, claims and encumbrances),  and shall notify the Shareholders
of such  determination  and the bases on which such determi  nation was made. At
its own cost and expense, either Shareholder may, for a period of seven (7) days
following such determination,  indicate errors in the calculation of the Buy-Out
Price to the Buy-Out Appraiser, who shall make any necessary adjust ments to the
Buy-Out  Price within seven (7) days of receiving  notification  of such errors;
provided,  however,  that the  Buy-Out  Price as  ultimately  determined  by the
Buy-Out  Appraiser in its discretion  shall be final and binding on the Parties;
and  provided,  further,  that  the  Buy-Out  Price  shall be  decreased  by all
reasonable,  out-of-pocket  expenses and costs  (including all reasonable  legal
costs) incurred by the  Nonwithdrawing  Shareholder as a result of the situation
giving rise to the activation of buy-out  rights,  the costs of the valuation to
be performed  pursuant to this Section 7.6(a) and, in the event the  Withdrawing
Shareholder  is a Breaching  Shareholder,  by an amount equal to 5% of the price
determined by the appraiser.

                  (b)  Notwithstanding  the  irrevocability of the option of the
Nonwithdrawing  Shareholder  set forth in  Section  7.6(a),  the  Nonwithdrawing
Shareholder  shall have the right,  exercisable  by giving written notice to the
Withdrawing  Shareholder  within ten (10)  Business  Days  after  receipt of the
appraised price from the merchant bank or other third party designated  pursuant
to Section  7.6(a) (the  "Rejection  Notice"),  to elect not to proceed with the
purchase  of the  Withdrawing  Shareholder's  Shares.  In  such  an  event,  the
Nonwithdrawing  Shareholder  shall have the right (i) to leave the Shareholders'
relative shareholdings  unaffected by the event giving rise to the activation of
buy-out  rights  hereunder  or  (ii) to  declare  a  Deadlock  and  trigger  the
withdrawal and sale  provisions of Section 7.8(b).  Unless the Rejection  Notice
contains the Nonwithdrawing Shareholder's

                                       25
<PAGE>

election to declare a Deadlock,  it shall be deemed to have elected to leave the
Shareholders' relative shareholdings unaffected.

                  (c)  Notwithstanding  any other provision in this Agreement to
the  contrary,  the  exercise by the  Nonwithdrawing  Shareholder  of the option
specified  in Section  7.6(a) to purchase  the Shares  owned by the  Withdrawing
Shareholder  shall be deemed to have been  canceled  if at any time prior to the
determination of the price to be paid for the Withdrawing  Shareholder's  Shares
pursuant to Section 7.6(a) above,  the Withdrawing  Shareholder (i) remedies the
breach or violation giving rise to the Breach Buy-Out Notice (including,  in the
case of a Payment  Default,  by curing the Payment  Default  pursuant to Section
6.2),  (ii) cures the situation  giving rise to the  Bankruptcy  Buy-Out  Notice
(including  without  limitation  by  definitively   terminating  any  proceeding
referred to in Section 7.4(a)(i), or obtaining the vacation,  discharge, stay or
bonding  pending  appeal  of  the  order  for  relief  referred  to  in  Section
7.4(a)(ii)),  or (iii)  reverses  the  situation  giving  rise to the  Change of
Control (including without limitation  obtaining the rescission of any agreement
giving  rise to such  Change of  Control),  as the case may be, and (X) pays all
costs associated with the valuation  conducted  pursuant to Section 7.6(a) above
and (Y) reimburses the Nonwithdrawing  Shareholder and Britannia for any and all
reasonable,  out-of-pocket  expenses and costs  (including all reasonable  legal
costs)  incurred by such party as a result of the  situation  giving rise to the
activation of buy-out rights under Section 7.6(a).

                  7.7  Transfer  Mechanics.  (a) In the  event  of any  sale  or
purchase of Shares pursuant to this Article VII, each Shareholder  shall use its
best  efforts to do all  things  reasonably  necessary  to  consummate  any such
purchase as promptly as practicable,  including without limitation amending this
Agreement,  the Articles and any other agreement between the  Shareholders,  and
entering into  agreements and  instruments  with third parties and obtaining any
necessary shareholder and governmental approvals.  Each party to any purchase of
Shares  pursuant  to this  Section 7.7 shall bear its own  expenses  incurred in
connection with the consummation of such purchase of Shares.

                  (b) The completion of any purchase of Shares  pursuant to this
Article VII shall take place as promptly as  practicable  after the execution of
all necessary agreements and instruments,  the receipt of any necessary consents
and the comple tion of all matters  necessary  to  consummate  such  purchase in
accordance with Section 7.7(a) above. At such completion:

                           (i) the Withdrawing Shareholder, or in the event of a
         sale pursuant to Section  7.8(b) each  Shareholder,  shall transfer the
         Shares so purchased to the Purchaser  with full title  guarantee,  free
         and clear of all liens,  security  interests  or adverse  claims of any
         kind or nature,  and shall 

                                       26
<PAGE>


         deliver to such  purchaser  any  certificates  representing  the Shares
         purchased, duly endorsed for transfer;

                  (ii) the  Withdrawing  Shareholder,  or in the event of a sale
         pursuant to Section 7.8(b) each Shareholder,  shall cause the following
         persons to resign:

                           (A) each member of the Britannia  Board  nominated by
                  it; and

                           (B) any officer  nominated  by it or by any member of
                  the Britannia Board nominated by it;

                  (iii) the purchaser(s)  shall deliver to the Withdrawing Share
         holder,  or in the event of a sale  pursuant  to Section  7.8(b) to the
         accounts specified by each Shareholder, in full payment of the purchase
         price of the Shares purchased, the amount determined in accordance with
         Section 7.6(a) or 7.8(b);

                  (iv) the  Shareholders  shall amend this  Agreement,  the Arti
         cles  and  any  other  agreement   between  the   Shareholders  as  the
         Nonwithdrawing Shareholder may direct, in each case in such a manner so
         as to preserve the  Nonwithdrawing  Shareholder's  relative  rights and
         obligations under such documents;

                  (v) subject to stamping, Britannia shall enter the transfer of
         Shares in the Shareholders' Register;

                  (vi) neither  Shareholder  shall make any  representations  or
         warranties to the other  Shareholder in connection with any purchase of
         Shares  pursuant  to this  Article  VII other than  those  specifically
         identified in Section 7.7(b)(i);

                  (vii) any purchase  pursuant to this Article VII shall relieve
         the Withdrawing  Shareholder of its  liabilities and obligations  under
         this  Agreement  (other  than any  obligations  under  any  obligations
         pursuant to Article XI hereof); and

                  (viii) by signing this Agreement,  the Withdrawing Shareholder
         shall be deemed to have given a  power-of-attorney  to the Chair man of
         the  Board  to  take,  in  its  name  and on its  behalf,  all  actions
         contemplated  by this  Section  7.7(b);  provided,  however,  that such
         power-of-attorney  shall be valid  if,  and  only if,  the  Withdrawing
         Shareholder  shall  have  refused to take,  or shall have  unreasonably
         delayed the taking of, any action

                                       27

<PAGE>

         authorized by this Section  7.7(b);  and provided,  further,  that such
         power of attor ney shall not authorize  any act  prohibited by the laws
         of England and Wales,  the Listing  Rules of the Stock  Exchange or the
         City Code on Takeovers and Mergers.

                  (c) The Shareholders acknowledge and agree that they shall use
all reasonable  endeavors to obtain any shareholder  approval required by Law in
connec tion with any sale or purchase of Shares  pursuant to this  Article  VII.
Subject to Section 7.9(a) below, the Shareholders  further acknowledge and agree
that  neither  Shareholder  shall be  obligated to complete any sale or purchase
pursuant  to this  Article  VII  until  it  shall  have  obtained  any  required
shareholder  approval.  For  purposes of this  Article VII  (including,  for the
avoidance of doubt,  all previous and  subsequent  Sections of this Article VII)
and  subject  to the  foregoing  provisions  of  this  Section  7.7(c),  neither
Shareholder shall be deemed to be in breach of any obligations to act within set
time limits if such act requires  shareholder  approval,  until such time as any
required shareholder approval has been obtained, in which event such time limits
shall be deemed to run from the date on which such consent is obtained.

                  7.8  Deadlock.  In the event of the  occurrence of a Deadlock,
the Shareholders hereby agree as follows:

                  (a) Withdrawal by one Shareholder. In the event that, upon the
occurrence of a Deadlock, one Shareholder (the Withdrawing  Shareholder) desires
to terminate  its  participation  in Britannia  and the other  Shareholder  (the
Nonwithdrawing  Shareholder)  does not, the procedures set forth in Sections 7.6
and 7.7 above shall govern the transfer of such Withdrawing Shareholder's Shares
to  such  Nonwithdrawing   Shareholder;   provided,   that  such  Nonwithdrawing
Shareholder  shall initiate such procedures by providing a Buy-Out Notice within
thirty (30) days of the  occurrence of a Deadlock and such Buy-Out  Notice shall
constitute an Option Exercise Notice; and provided, further, that the price paid
by the Nonwithdrawing  Shareholder for the Shares of the Withdrawing Shareholder
shall not be reduced by the amount of any damages  suffered or costs incurred by
the Nonwithdrawing  Shareholder or by any discount factor provided for elsewhere
herein.

                  (b)   Withdrawal  by  both   Shareholders.   In  the  event  a
Nonwithdrawing   Shareholder   invokes  this  Section  7.8(b)  pursuant  to  the
provisions  of Sections 7.3 - 7.6 hereof or 7.6(b)  hereof or in the event that,
upon the occurrence of a Deadlock,  both Shareholders  desire to terminate their
participation  in the Strategic  Alliance  established  by this Agreement and to
sell  their  entire  shareholdings  in,  or  substantially  all the  assets  of,
Britannia to a third party, the Shareholders shall attempt,  through discussions
between their  respective chief executive  officers,  to agree upon the price at
which such shareholdings or such assets 

                                       28
<PAGE>

are to be sold. If such  agreement  cannot be reached within twenty (20) days of
the occurrence of a Deadlock or the  invocation of this Section 7.8(b)  pursuant
of  Sections  7.3 - 7.6 hereof,  an  independent  merchant  bank (or other third
party) shall be designated to organize the sale of Britannia's  entire  business
(whether through a sale of one hundred percent (100%) of the Shares in Britannia
or  otherwise)  through a competitive  open-market  auction or otherwise as such
independent  merchant  bank (or other third  party)  shall deem  appropriate  to
maximize the value to be obtained. The independent merchant bank (or other third
party) shall be designated  as provided in Section  7.6(a);  provided,  however,
that such  merchant  bank  shall be  designated  within  sixty  (60) days of the
occurrence  of such  Deadlock  and in no  event  shall  such  auction  or  other
disposition  process be  consummated  in less than one hundred and twenty  (120)
days from the date such Deadlock  occurs,  unless the  Shareholders  unanimously
agree in writing  otherwise;  and  provided,  further,  that the share  transfer
formalities  set forth in  Sections  7.7(a) and (b) above  shall in any event be
respected.

                  (c) Withdrawal by Neither Shareholder. In the event that, upon
the occurrence of a Deadlock,  neither  Shareholder  desires to sell or transfer
its interest in Britannia,  an  independent  merchant bank or other  independent
third party (the "Bid  Appraiser") to be designated  jointly by the Shareholders
or, if the  Shareholders  cannot  agree on the  designation  of a Bid  Appraiser
within twenty (20) days from the occurrence of such Deadlock,  by an independent
merchant  bank (or other third party)  designated  by two  independent  merchant
banks  to  be  designated  as  provided  in  Section  7.6(a),  shall  conduct  a
competitive  bidding  process  between the  Shareholders.  Britannia's  managing
director  shall  provide  the  Shareholders  with  such  information  concerning
Britannia  and  its  subsidiaries  (and  their  operations,  results,  financial
condition or prospects) as the Shareholders may reasonably require in connection
with such bidding  process.  Each of IM and Mentmore  shall  provide an all cash
sealed  bid for one  hundred  percent  (100%) of the  equity in  Britannia  (the
"Equity  Valuation")  to such Bid  Appraiser and the  Shareholder  providing the
highest  such  sealed bid the  ("Purchasing  Shareholder")  shall be required to

                  7.9 Other  Transfers.  (a) In the event any  Shareholder  (the
"Trans ferring  Shareholder") desires to transfer all (but not less than all) of
its Shares to any third party in any  circumstance not covered by the provisions
of Sections 7.1 - 7.8 above,  such  Shareholder must first offer in writing (the
"Initial  Offer") such Shares to the other  Shareholder  (the  "Non-Transferring
Shareholder") at a price to be determined by the Transferring Shareholder.  Such
Initial Offer must specify all material terms and conditions (including, without
limitation,   all   representations   and   warranties   to  be  made   and  any
indemnification to be provided) on which the Trans ferring Shareholder  proposes
to  transfer  its Shares and must  remain  open for a period of ninety (90) days
(the  "Initial  Offer  Period")  from the date on which  such  Initial  Offer is
received  by the  Non-Transferring  Shareholder.  In the event (i) such  Initial
Offer has not been accepted (such  acceptance to be  unconditional  save for any
requirement  that  shareholder  approval  be obtained in relation to the Initial
Offer) by the  Non-Transferring  Shareholder  at the  conclusion  of the Initial
Offer Period or (ii) such Initial Offer has been so accepted but the transfer of
Shares to the Non-Trans  ferring  Shareholder is not completed within forty-five
(45) days of the date of such acceptance (such period to be extended for as long
as any act or  decision  of any  governmental  authority  or body  prevents  the
completion of such  transfer,  and for the avoidance of doubt,  to be subject to
Section  7.7(c)),  the  Transferring  Shareholder  may offer  such  Shares  (the
"Subsequent  Offer")  to a third  party for a period of one  hundred  and eighty
(180) days after the  expiration  of the Initial  Offer Period (the "Third Party
Offer Period"), the Transferring Shareholder may not accept any offer at a price
below the  price at which,  or on terms and  conditions  more  favorable  to the
Transferring  Shareholder than those on which, such  Transferring  Shareholder's
Shares were offered to the Non-Transferring  Shareholder pursuant to the Initial
Offer.

                  (b) In the  event  (i)  the  Subsequent  Offer  has  not  been
accepted (such  acceptance to be  unconditional  save for any  requirement  that
shareholder  approval be obtained  in relation to the  Subsequent  Offer) at the
conclusion  of the Third Party Offer  Period or (ii) such  Subsequent  Offer has
been so accepted but the transfer of Shares to the Non-Transferring  Shareholder
is not  completed  within  forty-five  (45) days of the date of such  acceptance
(such  period  to be  extended  for as  long  as  any  act  or  decision  of any
governmental authority or body prevents the completion of such transfer and, for
the avoidance of doubt,  to be subject to Section  7.7(c) above) the  Subsequent
Offer shall lapse and the Transferring  Shareholder may only transfer its Shares
by recommencing and respecting the procedure set forth in Section 7.9(a) above.

                  7.10 Other Transfer  Conditions.  (a) No transfer of Shares to
any third  party  (including  a transfer  permitted  by the second  sentence  of
Section  7.10(b))  shall be permitted or registered in  Britannia's  shareholder
register unless and until any such third party has delivered to Britannia a Deed
of Adherence in the form attached as Exhibit I hereto.

                  (b) Except for a sale pursuant to and in  accordance  with the
provi sions of Section 7.1 - 7.9 or this Section  7.10(b),  or a pledge pursuant
to and in  accordance  with  Section  4.5, no  Shareholder  shall sell,  assign,
exchange,  encumber,  distribute,  transfer, pledge, or otherwise dispose of, by
gift or otherwise,  any Shares or any rights  associated  therewith  (including,
without limitation, any rights to receive dividends or other distributions owned
by  such   Shareholder   at  the  date   hereof  or  at  any  time   hereafter).
Notwithstanding the foregoing sentence,  either Shareholder may transfer all but
not less than all of its Shares to a Wholly  Owned  Subsidiary  of the Parent or
Mentmore,  as the case may be, subject to such Wholly Owned Subsidiary  entering
into a Deed of Adherence in the form attached as Exhibit I hereto; provided that
in the event any such transferee  ceases to be a Wholly Owned  Subsidiary of the
Parent or  Mentmore,  as the case may be, such  transferee  shall  transfer  the
relevant Shares to the Parent or Mentmore or another Wholly Owned  Subsidiary of
the Parent or Mentmore.

                  (b) The  execution  and  delivery  of this  Agreement  by each
Party, and the consummation of the transactions  contemplated hereby, (i) do not
require the consent,  approval,  authorization,  notification,  registration  or
qualification of or with any governmental authority, and (ii) do not result in a
breach or  violation  of any of the terms and  provisions  of, or  constitute  a
default under, (A) any Material indenture, mortgage, deed of trust, lease or any
other  agreement or  instrument  of  whatsoever  nature to which such Party is a
party or by which it or any of its  property  or assets  is  bound,  or (B) such
Party's  memorandum  or  articles  of  association,   charter,   certificate  of
incorporation,  by-laws  (or  similar  document)  or  any  of  its  constitutive

investigation  conducted  by any  Party or any  information  which any Party may
receive.
                                   ARTICLE IX

                        GOVERNING LAW; DISPUTE RESOLUTION

                  9.1  Governing  Law. This  Agreement  shall be governed by and
construed in accordance with the laws of England and Wales without giving effect
to the principles of conflicts of laws thereof.

                  9.2  Conciliation.  (a) Subject to the  provisions  of Section
7.6(a)  hereof,  any  dispute  arising  out of or  relating  to this  Agreement,
including,  without  limitation,  the  interpretation  of any  provision of this
Agreement  or the  breach,  termination  or  invalidity  of  this  Agreement  (a
"Dispute")  shall be submitted for resolution to a committee (the  "Conciliation
Committee") pursuant to this Section 9.2; provided,  however,  that in the event
any situation  giving rise to a Buy-Out Notice is submitted to the  Conciliation
Committee  prior to the  exercise  of  buy-out  or  withdrawal  and sale  rights
pursuant to Section  7.6(a),  the  Conciliation  Committee  shall only determine
whether or not the  situation  giving rise to the Buy-Out  Notice in fact exists
and has not  been  cured.  If the  Conciliation  Committee  determines  that the
Nonwithdrawing  Shareholder had no grounds for the delivery of a Buy-Out Notice,
such Nonwithdrawing  Shareholder shall be obligated to reimburse the Withdrawing
Shareholder for all out-of-pocket costs and expenses, including reasonable legal
expenses, incurred by the Withdrawing Shareholder as a result of the delivery of
the Buy-Out Notice.  The  Conciliation  Committee shall be composed of the chief
executive or other nominee of each Shareholder (or a delegate thereof) who shall
have full power and authority to resolve any Dispute. The Conciliation Committee
shall  meet as  necessary  in order to resolve  the  Dispute.  The  Conciliation
Committee shall attempt to resolve such Dispute by mutual  agreement  within ten
(10) Business Days of referral of such Dispute to it;  provided,  however,  that
the Parties may agree to lengthen  such period.  Decisions  of the  Conciliation
Committee shall be final and binding on the Parties.

                  (b) No  Shareholder  may  submit any  Dispute  to  arbitration
unless and until the procedure specified in Section 9.2(a) has been followed.

                  9.3 Arbitration. (a) Any dispute the Conciliation Committee is
unable to resolve within the period specified in Section 9.2(a) shall be finally
settled by arbitration  by three  arbitrators  appointed in accordance  with the
Rules of Arbitra tion of the  International  Chamber of Commerce ("ICC") then in
effect,  except as modified  herein.  The  arbitration  shall be held in London,
England. The arbitration proceedings shall be conducted,  and the award shall be
rendered, in English.

<PAGE>


                  (b) The  Parties  expressly  waive any rights they may have to
litigate or resolve any Dispute  otherwise than in accordance  with this Article
IX and the  Parties  hereby  waive any  rights of  application  or appeal to the
courts of England to the fullest extent  permitted by law in connection with any
question of law arising in the course of the  arbitration or with respect to any
award made,  except for actions to enforce an arbitral award and actions seeking
interim,  interlocutory  or other provi sional  relief in any court of competent
jurisdiction.

                  (c) The award shall be final and  binding  upon the Parties as
from the date rendered,  and shall be the sole and exclusive  remedy between the
Parties  regarding  any claims  (including,  without  limitation,  any claim for
specific perfor mance of any obligation  hereunder),  counterclaims,  issues, or
accounting presented to the arbitral tribunal and judgment upon any award may be
entered in any court having jurisdiction;  provided,  however, that in the event
any situation  giving rise to a Buy-Out Notice is referred to arbitration  prior
to the  exercise of buy-out or  withdrawal  and sale rights  pursuant to Section
7.6(a),  the arbitrators  shall only determine whether the situation giving rise
to the  Buy-Out  Notice in fact  exists and has not been  cured;  and  provided,
further,  that if the  arbitral  tribunal  determines  that  the  Nonwithdrawing
Shareholder  had  no  grounds  for  the  delivery  of  a  Buy-Out  Notice,  such
Nonwithdrawing  Shareholder  shall be  obligated to  reimburse  the  Withdrawing
Shareholder for all out-of-pocket costs and expenses, including reasonable legal
expenses, incurred by the Withdrawing Shareholder as a result of the delivery of
the Buy-Out Notice.

                  (d) Subject to 9.2(a) and (b) above, each of the Parties shall
bear its own costs  and  expenses  and an equal  share of the  arbitrators'  and
administrative fees of the arbitration.

                  (e) Any monetary  award shall be made and promptly  payable in
Pounds sterling free of any tax,  deduction or offset, and the arbitral tribunal
shall be authorized in its discretion to grant pre-award and post-award interest
at commercial  rates. Any costs,  fees, or taxes incident to enforcing the award
shall,  to the maximum  extent  permitted  by law, be charged  against the Party
resisting such enforcement.

                  (f) This  Agreement  and the  rights  and  obligations  of the
Parties  shall  remain  in full  force  and  effect  pending  the  award  in any
arbitration proceeding here under.

the  arbitration  shall be in  accordance  with the  provisions  of Section 13.4
hereof.

Information as defined in Section 11.2 hereof is disclosed to either Shareholder
or  the  Parent,  such  Shareholder  or  Parent  agrees  not  to  disclose  such
Confidential  Information to any other Person without the prior written  consent
of the owner of such Confidential Information; provided, however, that each such
Shareholder or the Parent may, subject to Section 11.3 and if necessary in order
to further its business  objectives,  disclose such Confidential  Information to
(i)  any  of  its   officers,   directors,   employees,   legal  or   accounting
representatives  who has a need to know such  Confidential  Information and (ii)
its investors and investment bankers and such investors' or investment  bankers'
respective  representatives,  it  being  understood  that the  Party  disclosing
Confidential  Information  to any such  person  shall be liable for any  further
disclosure  of  such  Confidential  Information  by  such  person  in  a  manner
inconsistent  with the provisions of this Article XI. The restrictions set forth
in this  


                                       34

this Agreement, "Confidential Information" shall mean any financial, commercial,
technical or other nonpublic  information of any Party or any Affiliate thereof,
which is disclosed  (whether  prior to or after the date hereof) to any Party or
any Affiliate thereof in connection with the Records  Management  Business or in
connection  with  the  activities  of  Britannia  or any  of  its  Subsidiaries,
including  without  limitation any  engineering or other  drawings,  data bases,
computer software,  designs,  specifications,  technical information,  know-how,
documentation,  price books, client lists and service material, of all kinds and
in whatsoever form; provided, however, that "Confidential Information" shall not
include any information so disclosed if:

                             (i) the  recipient of such  information  shall have
         had  knowledge  of such  information  prior to the  date on which  such
         recipient received it from a Party or an Affiliate of a Party;

                             (ii) such information shall have entered the public
         domain through no fault of such recipient; or

         information  from a third  party in such a manner  that such  recipient

         such information.

                  11.3  Disclosure  Required by Law or Court Order. In the event

Confidential  Information  supplied  to it by any other  Person,  the  recipient
required to make such disclosure  shall,  in a manner  consistent with such Law,
promptly  notify the other  Person or Persons  involved  so that such  Person or
Persons may seek an  appropriate  protective  order  and/or  waive the  required
recipient's  compliance  with Section  11.1.  In the event that such  protective
order or other  remedy is not  obtained,  then the  recipient or  recipients  so
required to disclose Confidential Information shall furnish only that portion of
such Confidential Information that is legally required to be disclosed.

                  11.4 Use of Confidential Information.  During the term of this

                                       35

                  13.5  Counterparts.  This  Agreement may be executed in one or
more counterparts,  each of which shall be considered one and the same agreement
and shall become  effective  when two or more  counterparts  have been signed by
each of the Parties and delivered to the other Parties.

                  13.6  Entire  Agreement;  No Third Party  Beneficiaries.  This
Agreement  (including the documents and the instruments referred to herein): (a)
constitutes  the  entire  agreement  and  supersede  all  prior  agreements  and
understandings,  both  written and oral,  among the Parties  with respect to the
subject  matter  hereof and thereof,  and (b) is not intended to confer upon any
Person  other  than the  Parties  hereto  and  thereto  any  rights or  remedies
hereunder.

                  13.7  Severability.  Any term or provision  of this  Agreement
that is held by a court  of  competent  jurisdiction  or other  authority  to be
invalid,  void or unenforceable  in any situation in any jurisdiction  shall not
affect the validity or  enforceability  of the  remaining  terms and  provisions
hereof or the validity or  enforceability  of the offending term or provision in
any other  situation or in any other  jurisdiction.  If the final  judgment of a
court of competent  jurisdiction  or other  authority  declares that any term or


                                       38

<PAGE>

provision hereof is invalid,  void or unenforceable,  the Parties agree that the
court  making  such  determination  shall  have the power to reduce  the  scope,
duration,  area or  applicability  of the term or provision,  to delete specific
words or  phrases,  or to replace any  invalid,  void or  unenforceable  term or
provision with a term or provision that is valid and  enforceable and that comes
closest to  expressing  the  intention of the invalid or  unenforceable  term or
provision.

                  13.8 Time of Essence.  Subject to Section 7.7(c) hereof,  each
of the Parties  hereto  hereby  agrees  that,  with regard to all dates and time
periods set forth or referred to in this Agreement, time is of the essence.

                  13.9  Extension;  Waiver.  At any time prior to the closing of
the transactions  contemplated in the Transaction Agreement, the Parties may (a)
extend the time for the  performance of any of the  obligations or other acts of
the other  Parties,  (b)  waive  any  inaccuracies  in the  representations  and
warranties of the other Parties  contained in this  Agreement or in any document
delivered  pursuant  to this  Agreement  or (c)  waive  compliance  by the other
Parties with any of the  agreements or conditions  contained in this  Agreement.
Any  agreement  on the part of a party to any such  extension or waiver shall be
valid only if set forth in an  instrument  in  writing  signed on behalf of such
party.  The failure of any party to this  Agreement  to assert any of its rights
under this Agreement or otherwise shall not constitute a waiver of those rights.

                  13.10  Assignment.  Neither  this  Agreement  nor  any  of the
rights,  interests  or  obligations  hereunder  shall be  assigned by any of the
Parties  hereto  (whether by  operation of law or  otherwise)  without the prior
written  consent of the other Party,  except that each of the  Shareholders  may
assign,  in its  sole  discretion,  any or all  of  its  rights,  interests  and
obligations  hereunder to any Wholly Owned Subsidiary;  provided any such Wholly
Owned Subsidiary must execute a Deed of Adherence in  substantially  the form of
Exhibit I hereto;  and  provided,  further,  that in the event any Wholly  Owned
Subsidiary  to whom such rights,  interests or  obligations  have been  assigned
ceases to be a Wholly Owned  Subsidiary,  the rights,  interests or  obligations
assigned  to such  Wholly  Owned  Subsidiary  must be  reassigned  either to the
relevant  Shareholder  or  another  Wholly  Owned  Subsidiary  of  the  relevant
Shareholder  (such  subsidiary  being required to execute a Deed of Adherence in
substantially the form of Exhibit I hereto).  Subject to the preceding sentence,
this Agreement shall be binding upon, inure to the benefit of and be enforceable
by the Parties and their respective permitted successors and assigns.

                  13.11 Headings.  The headings  contained in this Agreement are
for convenience of reference only and shall not affect in any way the meaning or
interpretation of this Agreement.


                  13.12  Section  References.  All  references  to Articles  and
Sections  herein are to the  Articles  and  Sections  of this  Agreement  unless
otherwise specified.

                  13.13  Relationship Between the Parties.

                  (a) No  provision  of this  Agreement  shall be  construed  as
creating a  partnership,  agency or  fiduciary  relationship  between any of the
Parties.

                  (b) The relationship of the Shareholders to Britannia shall be
that of shareholders, except as might otherwise be provided in any other written
agreement between one or more of the Shareholders and Britannia.  No Shareholder
shall  act  as  an  agent  for  or on  behalf  of  Britannia,  except  as  might
specifically be provided in any other written  agreement  between  Britannia and
such  Shareholder.  Each  Shareholder  shall  conduct its affairs with regard to
third parties so as to avoid the  appearance or creation of any other or greater
relationship  between such Shareholder and Britannia.  No Shareholder shall take
any action on behalf of or binding on Britannia  without the  explicit  approval
and authorization of Britannia.

                  (c) Any agreement  entered into by a Party which  violates any
provision  of  this  Agreement,  or is  otherwise  outside  the  scope  of  this
Agreement, shall not be binding on the other Party or on Britannia, and only the
Party entering into such agreement shall be subject to any liability which might
arise therefrom.

                  13.14 Voting.  Each  Shareholder  shall take,  and shall cause
each  member of the Board  nominated  by it to take,  all actions  necessary  to
implement  the  provisions  of  this  Agreement,  except  such  actions  as  are
indisputably illegal or invalid under applicable law.

                  13.15 News Releases.  Each  Shareholder  agrees that no public
release or  announcement  concerning  the execution of this  Agreement  shall be
issued  by  such  Shareholder  except  in  accordance  with  Section  6.6 of the
Transaction Agreement.

                  13.16 Precedence of Agreement.  Where the context so requires,
the provisions of this Agreement  shall have  precedence  over the provisions of
the Articles of Association as amended from time to time.
