                        REPRESENTATIONS AND WARRANTIES
                          OF EACH OF THE SHAREHOLDERS
 
  Except as disclosed in the letter of disclosure (the "Shareholders
Disclosure Letter") delivered to Buyer in connection herewith and initialled
by the Buyer and each of the Shareholders for identification, each of the
Shareholders severally and not jointly represents and warrants to, and agrees
with, Buyer as follows:
 
  3.1 Title to Shares. Such Shareholder has good and marketable title, and
full beneficial ownership, in and to the ET Shares shown as being held of
record by such Shareholder on Exhibit A hereto, and such ET Shares are, and on

Shareholder and constitutes the legal, valid and binding obligations of such
Shareholder, enforceable against such Shareholder in accordance with its
terms, subject to applicable bankruptcy, insolvency, moratorium,
reorganization or similar laws affecting creditors' rights generally and
subject to general equitable principles (regardless of whether such
enforceability is considered in a proceeding in equity or at law).
 
  3.3 No Violation. The execution, delivery and performance of this Agreement
by such Shareholder and the consummation by such Shareholder of the
transactions contemplated hereby will not (a) violate any provision of law,
rule, regulation, order, writ, judgment, injunction, decree, determination or
award applicable to such Shareholder, (b) require the consent, waiver,
approval or authorization of or any filing by such Shareholder with any person
or governmental authority, or (c) violate, result (with or without notice or
the passage of time, or both) in a breach of, or give rise to the right to
terminate, accelerate or cancel any obligation under, or require the payment
of any fee, or constitute (with or without notice or the passage of time, or
both) a default under, any indenture, mortgage, lien, order, judgment,
ordinance, regulation, decree or other agreement or instrument to which such
Shareholder is subject or bound which, in any such case described in clauses
(a) through (c), could reasonably be expected to materially and adversely
affect or interfere in any way with such Shareholder's ability to consummate
the transactions contemplated by this Agreement, or (d) result in the creation
of any Encumbrance upon any of the ET Shares shown as being held of record by
such Shareholder on Exhibit A hereto. There are no actions, proceedings,
claims, complaints, grievances or investigations pending or, to the knowledge
of such Shareholder, threatened against such Shareholder that could be
reasonably expected to materially and adversely affect such Shareholder's
ability to consummate the transactions contemplated by this Agreement.

any merger, consolidation, liquidation, dissolution, recapitalization or other
reorganization of either Company or any Subsidiary or to enter into any
agreement with respect thereto.
 
                                       3

 
  3.6 Regulation S Representations and Covenants.
 
    (a) Such Shareholder understands and acknowledges that: (i) the Buyer
  Shares have not been and will not be registered under the Securities Act of
  1933, as amended (the "Securities Act"), or under any state securities or
  blue sky laws, and may not be offered, sold, transferred, pledged or
  otherwise disposed of in the United States or to, or for the account or
  benefit of, any "U.S. person" (as defined in Regulation S), unless they are
  registered under the Securities Act and any applicable state securities or
  blue sky laws in exemptions from such laws are available; and (ii) the
  Buyer Shares are being offered and sold in a manner intended to comply with
  the conditions contained in Regulation S, which permits securities to be
  sold in "offshore transactions" (as defined in Regulation S), subject to
  certain terms and conditions. Such Shareholder represents and warrants that
  he or she is not purchasing the Buyer Shares in any transaction or series
  of transactions that, although in technical compliance with Regulation S,
  is part of a plan or scheme to evade the registration provisions of the
  Securities Act.
 
    (b) Such Shareholder is not a "U.S. person" and is not acquiring the
  Buyer Shares for the benefit of any "U.S. person." Such Shareholder is
  knowledgeable, sophisticated and experienced in making, and qualified to
  make, decisions with respect to investments in securities such as the Buyer
  Shares and has requested, received, reviewed and considered all information
  he or she deems relevant in making a decision to acquire the Buyer Shares.
 
    (c) During the period of 40 days following the Closing (the "Restricted
  Period"), such Shareholder will not engage in any activity for the purpose
  of, or which may reasonably be expected to have the effect of, conditioning
  the market in the United States for the Buyer Shares, or offer, sell,
  transfer, pledge or otherwise dispose of the Buyer Shares in the United
  States or to, or for the account or benefit of a "U.S. person." Any
  proposed offer, sale, transfer, pledge or other disposition of any of the
  Buyer Shares prior to the end of the Restricted Period will be subject to
  the prior delivery by the Shareholder to the Buyer of: (i) a written
  certification that the Buyer Shares have not been offered or sold in the
  United States or to, or for the account or benefit of, any "U.S. person";
  and (ii) a written certification of the proposed transferee, reasonably
  acceptable to the Buyer, confirming that such transferee is outside the
  United States, is not a "U.S. person," and that the transfer is otherwise
  permissible under Regulation S. Such Shareholder will not, directly or
  indirectly, offer, sell, pledge, transfer or otherwise dispose of (or
  solicit any offers to buy, purchase or otherwise acquire or take a pledge
  of) the Buyer Shares otherwise than in compliance with the Securities Act,
  any applicable state securities or blue sky laws and any applicable
  securities laws of jurisdictions outside the United States, and the rules
  and regulations promulgated thereunder.
 
    (d) Such Shareholder acknowledges that if he or she sells all or any part
  of the Buyer Shares in the United States, he or she (and/or certain persons
  who participate in any such sale) may be deemed, under certain
  circumstances, to be an "underwriter," as defined in Section 2(11) of the
  Securities Act. Such Shareholder understands that he or she should consult
  with United States legal counsel prior to offering or selling all or any
  part of the Buyer Shares in the United States.
 
    (e) During the period that is five business days immediately prior to the

                        REPRESENTATIONS AND WARRANTIES
                          OF THE MAJORITY SHAREHOLDER
 
  Except as disclosed in the letter of disclosure (the "Company Disclosure
Letter") delivered to Buyer in connection herewith and initialled by the Buyer
and the Majority Shareholder for identification, the Majority Shareholder
represents and warrants to Buyer as follows:
 
  4.1 Corporate Organization. Each of the Companies is a corporation duly
organized, validly existing and in good standing under the laws of England,
with all requisite corporate power and authority to own, operate and lease its
properties and to carry on its business as it is now being conducted, and is
qualified or licensed to do business and is in good standing in each
jurisdiction in which the failure to be so qualified or licensed could
reasonably be expected, individually or in the aggregate, to have a material
adverse effect upon the financial condition, prospects or results of
operations of the Companies and the Subsidiaries considered as a whole (a
"Company Material Adverse Effect"). True and complete copies of the Memorandum
and Articles of each Company have been delivered to Buyer.
 
  4.2 Subsidiaries. A true and complete list of all direct and indirect
subsidiaries other than the Dormant Subsidiaries (each, a "Subsidiary" and
collectively, the "Subsidiaries") of each of the Companies is set forth in the
Company Disclosure Letter. The Company Disclosure Letter also identifies the
inactive subsidiaries of the Companies (the "Dormant Subsidiaries"). None of
the Dormant Subsidiaries has any material assets or liabilities (contingent or
absolute) and none presently engages in any business activity. Since March 31,
1996 no Company or Subsidiary has paid any amounts to any of the Dormant
Subsidiaries, no amounts will be so paid at any time hereafter, and any net
intercompany payables of the Company and its Subsidiaries to the Dormant
Subsidiaries shall be forgiven or cancelled at the closing. As used in this
Article IV, references to a "Company" or the "Companies" shall, if appropriate
given the context of the representations being made, include each relevant
Subsidiary, even though no specific reference to any Subsidiary is so made.
Each Subsidiary is a corporation duly organized, validly existing and in good
standing under the laws of its jurisdiction of incorporation, except that with
respect to the U.K. Subsidiaries, such Subsidiaries have been duly registered
in England and Wales under the Companies Act 1985. In each case such
Subsidiaries have all requisite corporate power and authority to own, operate
and lease its properties and to carry on its business as it is now being
conducted, and is qualified or licensed to do business and is in good standing
in each jurisdiction in which the failure to be so qualified or licensed could
reasonably be expected, individually or in the aggregate, to have a Company
Material Adverse
 
                                       5

 
Effect. All of the issued shares of capital stock of each such Subsidiary have
been duly and validly authorized and issued, are fully paid and non-
assessable, and are owned directly or indirectly by one of the Companies, free
and clear of any and all Encumbrances. Except with respect to the ownership of
the Subsidiaries by the Companies, neither Company nor any Subsidiary owns,
directly or indirectly, any stock, partnership interest, joint venture
interest or other security, investment or interest in any other corporation,
organization, partnership, limited liability company or entity.
 
  4.3 Share Capital; Title to ET Shares.
 
    (a) Capital Stock. As of the date hereof, the authorized share capital of
  (i) ET consists in its entirety of five hundred seventy five (575) shares
  of (Pounds)1 each, of which five hundred seventy (570) are issued and
  outstanding, and (ii) ETE consists in its entirety of ten thousand (10,000)
  shares of (Pounds)1 each, eighty-two (82) of which are Class A Shares and
  nine thousand nine hundred and eighteen (9,918) of which are Class B
  shares, all of which are issued and outstanding. All of the issued shares
  of each of the Companies have been duly authorized and validly issued and
  are fully paid and non-assessable and except as set forth in the Company
  Disclosure Letter, free of preemptive rights with respect thereto and were
  issued in compliance with all applicable securities laws and regulations.
  There are no voting trusts or other agreements, arrangements or
  understandings with respect to the voting of the shares of the Companies to
  which either Company or, to the best knowledge (as defined in Section 9.2
  hereof) of the Companies, any other person is a party. There are no
  registration rights, subscriptions, options, warrants, rights, convertible
  securities or other agreements or commitments of any character relating to
  the issued or unissued share capital or other securities of either of the
  Companies and there are no outstanding contractual obligations of either of
  the Companies to repurchase, redeem or otherwise acquire or sell, issue or
  otherwise transfer any of the share capital thereof.
 
    (b) Title to Shares. Exhibit A hereto sets forth the record ownership of
  the ET Shares. To the best knowledge of the Companies, (i) each Shareholder
  has good and marketable title in and to the respective ET Shares set forth
  opposite such Shareholder's name on Exhibit A hereto, (ii) the ET Shares
  are, and on the Closing Date will be, free and clear of any and all
  Encumbrances, and (iii) on the Closing, upon consummation of the
  transactions contemplated by this Agreement, including delivery by Buyer of
  the consideration set forth in Sections 1.3 and 1.4 hereof, Buyer will
  acquire good and marketable title to all of the ET Shares and the US
  Shares, free and clear of any and all Encumbrances.
 
  4.4 Authority. Each Company has the full corporate power and authority to
execute and deliver this Agreement and each other agreement contemplated
hereby, to carry out its obligations hereunder and thereunder and to
consummate the transactions contemplated on its part hereby and thereby. The
execution, delivery and performance by each Company of this Agreement and the
consummation of the transactions contemplated on its part hereby have been
duly authorized by its Board of Directors and by the shareholders thereof, and
no other corporate proceedings on the part of either Company are necessary to
authorize the execution and delivery of this Agreement by such Company to

executed and delivered by each Company and constitutes the legal, valid and
binding obligations of each Company, enforceable against each Company in
accordance with its terms, subject to applicable bankruptcy, insolvency,
moratorium, reorganization or similar laws affecting creditors' rights
generally and subject to general equitable principles (regardless of whether
such enforceability is considered in a proceeding in equity or at law). Each
other agreement to be executed in connection with this Agreement on or prior
to the Closing Date will be duly executed and delivered by each Company, and
will constitute a legal, valid and binding obligation of each Company,
enforceable against each Company in accordance with its respective terms,
subject to applicable bankruptcy, insolvency, moratorium, reorganization, or
similar laws affecting creditors' rights generally and subject to general
equitable principles (regardless of whether such enforceability is considered
in a proceeding in equity or at law).
 
  4.5 No Violations or Consents. The execution, delivery and performance of
this Agreement by the Companies and the consummation by them of the
transactions contemplated hereby will not (a) violate or conflict
 
                                       6

 
with any provision of any law specifically applicable to their business or by
which any property or asset of theirs is bound, (b) require the consent,
waiver, approval, license or authorization of or any filing by them with any
public authority (other than (i) if necessary, the filing of a pre-merger
notification report under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended (the "HSR Act") and applicable U.K./EEC antitrust statutes,
and (ii) any other filings and approvals expressly contemplated by this
Agreement), (c) violate, conflict with, result in a breach of or the
acceleration of any obligation under, or constitute a default (or an event
which with notice or the lapse of time or both would become a default) under,
or give to others any right of termination, amendment, acceleration or
cancellation of, or result in the creation of any Encumbrance on any property
or asset of theirs pursuant to any provision of any charter or by-law,
indenture, mortgage, lien, lease, agreement, contract, instrument, order,
judgment, ordinance, regulation or decree to which either of the Companies are
subject or by which either Company or its respective properties or assets are
bound, or (d) result in a loss or adverse modification of any license, permit,
certificate, franchise or contract granted to or otherwise held by either of
the Companies which, in any such case described in clauses (a) through (d),
could reasonably be expected to have, individually or in the aggregate, a
Company Material Adverse Effect.
 
  4.6 Litigation. There are no actions, proceedings, claims, complaints,
grievances, investigations or unfair labor practice complaints or grievances
or investigations (collectively, "Actions") pending or, to the best knowledge
of the Companies, threatened against either Company, any Subsidiary or any of
their assets or properties before any court or governmental or regulatory
authority or body or arbitrator (an "Authority") which could reasonably be
expected to have a Company Material Adverse Effect. There are no Actions
pending or, to the knowledge of the Companies, threatened against either
Company or any Subsidiary that could be reasonably expected to materially and
adversely affect on their part the consummation of the transactions
contemplated by this Agreement. None of the assets or property of either
Company or any Subsidiary is subject to any order, judgment, injunction, writ
or decree, which could reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect.
 
  4.7 Financial Statements. Each Company has previously delivered to Buyer its
financial statements for the years ended June 30, 1991, 1992, 1993, 1994 and
1995, as audited by Watts Gregory & Daniel, which financial statements
included (a) a consolidated profit and loss account for the year then ended,
(b) a consolidated balance sheet as at such date, (c) a company balance sheet
as at such date, (d) a consolidated cash flow statement for the year then
ended, (e) a consolidated schedule of tangible fixed assets as at such date,
(f) a company schedule of tangible fixed assets as at such date and (g) notes
to the accounts for the year then ended (collectively, the "Audited Financial
Statements"). Each Company has also previously delivered to Buyer its
unaudited management accounts at March 31, 1996 (the "Unaudited Financial
Statements," and collectively with the Audited Financial Statements, the
"Financial Statements"). The Audited Financial Statements give a true and fair
view of the Companies as at the date (the "Accounting Date") on which such
accounts were made up and of the profits of each of the Companies for the
accounting reference period ending on that date, comply with all current
SSAP's applicable to a United Kingdom company and with the requirements of the
Companies Act 1985 and with all other applicable legislation, and each of the
said Audited Financial Statements properly reflect the financial position of
each of the Companies as at the relevant Accounting Date and were prepared in
accordance with the historical cost convention. "SSAP" for this purpose means
a Statement of Standard Accounting Practice in force at the relevant
Accounting Date as issued by the Institute of Chartered Accountants in England
and Wales. The Unaudited Financial Statements have been prepared in accordance
with the books and records of the Companies, contain no material inaccuracies,
and follow the same principles as consistently applied to the Audited
Financial Statements.
 
  4.8 No Liabilities. Neither Company nor any Subsidiary has any material
liabilities, obligations or commitments of any nature (whether absolute,
accrued, contingent or otherwise and whether matured or unmatured), including
without limitation, any liabilities due or to become due to any taxing
authority having jurisdiction over such entities, except (a) liabilities
reflected in, reserved against, or disclosed in the footnotes of, the balance
sheet of such Company or Subsidiary at March 31, 1996 included in the
Unaudited Financial
 
                                       7

 
Statements, and (b) liabilities, obligations or commitments incurred since
March 31, 1996 in the ordinary course of such Company's or Subsidiary's
business or that are not material to the business of the Companies and the
Subsidiaries, taken as a whole.
 
  4.9 Absence of Certain Changes or Events. Since March 31, 1996, each of the
Companies and the Subsidiaries have conducted their respective businesses in
the ordinary course and, except pursuant to this Agreement and the
transactions contemplated hereby, there has not been any:
 
    (a) material adverse change in the financial condition, assets,
  liabilities, business, operations, results of operations or prospects of
  either Company or any Subsidiary or any other event or condition which in
  any one case or in the aggregate has materially and adversely affected
  either Company or any Subsidiary or any event or condition which it is
  reasonable to expect will individually or in the aggregate materially
  adversely affect the Companies and the Subsidiaries taken as a whole (any
  such event being herein referred to as a "Company Material Adverse
  Change");
 
    (b) declaration, waiver or payment of any dividend or other distribution
  or payment (whether in cash, shares or property) with respect to the share
  capital of either Company or any Subsidiary, or any redemption, purchase or
  other acquisition of any of the securities of any Company or Subsidiary, or
  any other payment to any shareholder of any Company or Subsidiary in its
  capacity as a shareholder;
 
    (c) issuance by either Company or any Subsidiary of, or commitment by any
  of them to issue, any share capital or obligations or any securities
  convertible into or exchangeable or exercisable for shares or other
  securities; or
 
    (d) indebtedness for borrowed money incurred by either Company or any
  Subsidiary or any commitment to incur indebtedness for borrowed money
  entered into by such Company or Subsidiary, or any loans made or agreed to
  be made to such Company or Subsidiary other than pursuant to commitments or
  credit facilities existing on March 31, 1996 and described in the Unaudited
  Financial Statements (or replacements thereof described in the Company
  Disclosure Letter).
 
  4.10 Insurance. Each Company and Subsidiary has in full force policies of
insurance issued by insurers of good repute insuring it and its properties and
business against such losses and risks, and in such amounts, as in its best
judgment, after advice from its insurance broker, are acceptable for the
nature and extent of such business and its resources. No Company or Subsidiary
is in default with respect to any material provision contained in any
insurance policy, and none has failed to give any notice or present any
existing claims it has under its insurance policies in a timely fashion.
 
  4.11 Employee Benefits and Pension Scheme.
 
    (a) Except as set forth in the Company Disclosure Letter, there are no
  agreements, arrangements, customs or practice (whether legally enforceable
  or not) in operation for the provision of, or payment or contributions
  towards, and no Company or Subsidiary has any liability or obligation to
  pay, any "relevant benefits" (as defined in Section 612 of the United
  Kingdom Income and Corporation Taxes Act 1988 (the "Taxes Act of 1988")),
  pensions, gratuities, allowances, lump sums or other like benefits on or
  after retirement or death or during periods of sickness, accident,
  incapacity or disablement for the benefit of any employee or former
  employee of either Company or of any Subsidiary (each, an "Employee") or
  such Employee's dependents, nor has any proposal been announced or promise
  made to establish any such agreement, arrangement or practice.
 
    (b) There have been disclosed to Buyer true and correct copies of (i) the
  current trust deed and rules governing the Companies' Retirement Benefit
  Scheme (the "Company's Scheme"), including deeds of alteration, (ii) the
  current explanatory booklet issued to members of the Company's Scheme,
  (iii) all announcements to members of the Company's Scheme (or to Employees
  concerning the Company's Scheme) other than announcements to members of the

  incorporated into the documents referred to in paragraph (d)(i) and (ii),

  Employees, indicating name, sex, date of birth, date of joining the
  Companies or a Subsidiary, and current salary and (vii) schedules of
  benefit structures indicating the relevant benefits provided or to be
  provided for Employees under the Company's Scheme in respect of all
  different categories of membership.
 
    (c) To the best knowledge of the Companies, the pension arrangements of
  each Company and Subsidiary, including without limitation, the Company's
  Scheme (collectively, the "Pension Arrangements"), have, at all times, been
  administered in all material respects in accordance with all applicable
  laws, rules and regulations.
 
    (d) To the best knowledge of the Companies, no discretion or power has
  been exercised under the Company's Scheme in respect of the Employees to at
  any time provide benefits in excess of those specifically provided for in
  the Company's Scheme.
 
    (e) No undertaking or assurance (whether or not constituting a legal
  binding commitment) has been given to any Employee about the continuation
  of the Company's Scheme or any alteration to or exception from its terms or
  the increase or improvement of benefits.
 
    (f) There are not, at the date of this Agreement, any outstanding
  contributions due to or under any Pension Arrangement, or that may become
  due to or under any Pension Arrangement with respect to any period prior to
  the Closing, from any Company or Subsidiary or any Employee or former
  Employee, except with respect to any such outstanding contributions that
  have been reserved against in the Financial Statements or that have
  occurred in the ordinary course of business since April 1, 1996.
 
    (g) The Company's Scheme is exempt approved (within the meaning of
  Section 592(1) of the Taxes Act of 1988) and is contracted out (for the
  purposes of the Pension Schemes Act 1993) and, to the best knowledge of the
  Companies, there are not facts or circumstances which may cause the
  withdrawal of approval by the Inland Revenue or cancellation of the
  contracted out status by the Occupational Pensions Board.
 
    (h) In respect of any of the Employees: there are no Actions in progress,
  pending or, to the best knowledge of the Companies, threatened against the
  Company's Scheme, any of the Companies or Subsidiaries or any of their
  trustees; and, to the best knowledge of the Companies, there are no
  investigations, inquiries, complaints or disciplinary proceedings by or
  before any government body or the Pensions Ombudsman concerning the
  Company's Scheme and none are pending or threatened.

  the Employees have in relation to the each Pension Arrangement in all
  material respects performed, observed and complied with, and each such

  such Pension Arrangement and all regulations, orders, contracts,
  agreements, licenses or obligations of whatsoever nature, including without
  limitation, requirements of the United Kingdom Inland Revenue or the
  Occupational Pensions Board and of trust law, which affect each such
  Pension Arrangement or its operation; and all exercises or purported
  exercises of powers or discretions in relation to each such Pension
  Arrangement, including without limitation, the power of amendment, have
  been in all material respects proper and valid exercises of those powers or
  discretions.
 
                                       9

 
  4.12 Material Contracts and Other Agreements. The Company Disclosure Letter
discloses (a) all agreements or contracts whether or not fully performed
pursuant to which either Company or any Subsidiary has since July 1, 1995
acquired or disposed of any business or assets exceeding (Pounds)75,000 in
value, other than sales of inventory or contracts with suppliers, each in the
ordinary course of business; (b) all agreements containing covenants not to
compete on the part of either Company or any Subsidiary or otherwise
restricting the ability of such Company or Subsidiary in any material way to
engage in its business; (c) all material notes, mortgages, indentures, letters
of credit, guarantees, performance bonds and other obligations and agreements
and other instruments for or relating to any lending or borrowing (including
assumed debt) entered into by either Company or any Subsidiary or pursuant to
which any properties or assets of any Company or Subsidiary are pledged or
mortgaged as collateral; and (d) all agreements to which any of the Companies
or Subsidiaries is a party containing provisions restricting or providing
exclusive rights with respect to the development, manufacture or marketing of
products which, after the Closing, would be applicable to the business or
products of the Buyer or Buyer's Subsidiary (as defined in Section 5.2) by
reason of the transactions contemplated by this Agreement.
 
  4.13 Suppliers and Customers. The Companies have delivered to Buyer a list
which accurately sets forth (a) the ten (10) largest suppliers of the
Companies and the Subsidiaries (considered as a whole) for the nine months
ended March 31, 1996 (the "Large Suppliers"), (b) the amount of all payments
made to each Large Supplier for such fiscal period, (c) the ten (10) largest
customers or groups of related customers of the Companies and the Subsidiaries
(considered as a whole) for the nine months ended March 31, 1996 (the "Large
Customers") and (d) the amount of all payments made by such Large Customers
for such fiscal period. No supplier is a sole source of supply of any good or
service used by the Companies or by any Subsidiary. None of the Large
Suppliers or Large Customers has canceled or otherwise terminated, or
threatened in writing, by notice to any Company or Subsidiary, to cancel or
otherwise terminate, its relationship with either Company or with any
Subsidiary or, since March 31, 1996, decreased materially, or threatened to
decrease or limit materially, its services, supplies or materials to either
Company or any Subsidiary or its usage or purchase of the products or services
of such Company or Subsidiary, which, in any case, would result in a Company
Material Adverse Change.
 
  4.14 Real Property. The Company Disclosure Letter sets forth all freehold
and leasehold real property of the Companies. All such freehold and leasehold
real property is collectively referred to herein as the "Real Property." The
Real Property comprises all land and premises owned, occupied or used by, or
in the possession of, the Companies and Subsidiaries. The Companies have good
and marketable title to the freehold Real Property, and true and correct
copies of all leases concerning the leasehold Real Property have been
delivered to the Buyer. There is appurtenant to the Real Property each right
and easement necessary in all material respects for its existing and continued
use.
 
  4.15 Condition of the Real Property; Rights of Use; Liabilities.
 
    (a) Neither the Real Property nor any of its title deeds is subject to an
  encumbrance, agreement, obligation, condition, right, easement, exception,
  reservation, overriding interest (as defined in sub-section 70(1) of the
  Land Registration Act 1925) or other interest. There is no person in
  possession or occupation of, or who has or claims a right or interest of
  any kind in, the Real Property adversely to any Company's or Subsidiary's
  interest.
 
    (b) No Action concerning any Real Property is pending or, to the best
  knowledge of any Company or Subsidiary, threatened. To the best knowledge
  of each Company and Subsidiary, no matter exists which may give rise to a
  proceeding of that type. To the best knowledge of the Companies, there is
  no outstanding notice affecting the Real Property.
 
    (c) To the best knowledge of each Company and Subsidiary, there is no
  resolution or proposal for compulsory acquisition of the Real Property by a
  local or other authority.
 
    (d) Subject to the terms and conditions of the applicable leasehold
  agreements, where any Company or Subsidiary holds Real Property under a
  lease, tenancy or license, no person, including without limitation, the
  landlord or licensor, may bring the term to an end before the expiry of the
  lease, tenancy or license by
 
                                      10

 
  effluxion of time (except by forfeiture). Subject to the terms and
  conditions of the applicable leasehold agreements, to the best knowledge of
  the Companies there is no matter which could (i) entitle or require a
  person, including without limitation, a landlord or licensor, to forfeit or
  enter on, or take possession of, or occupy, the Real Property, (ii)
  restrict or terminate the Company's or Subsidiary's continued and
  uninterrupted possession or occupation of the Real Property or (iii)
  prevent or restrict the Real Property's development for which planning
  permission has been or is expected to be obtained. No rent or fee payable
  in respect of any of the Real Property is, as of the date hereof, being
  reviewed except where such reviews could not reasonably be expected to
  result in rent increases exceeding (Pounds)150,000 annually, in the
  aggregate. No person, including without limitation, a landlord or licensor,
  has elected to waive an exemption from payment by any Company or Subsidiary
  of value added tax in respect of a payment made under the lease, tenancy or
  license.
 
  4.16 Compliance with Laws. The Companies and the Subsidiaries are in
compliance with applicable laws, statutes, ordinances, rules and regulations,
orders or other requirements, including without limitation, applicable
franchise, building, planning, health, environmental, sanitation, safety,
employment relations and other laws, ordinances or regulations, other than
violations, if any, which, individually or in the aggregate, could not
reasonably be expected to have a Company Material Adverse Effect. Neither
Company nor any Subsidiary has received any notice from any person asserting a
present or past failure by either Company or any Subsidiary to comply in any
material respect with such laws, statutes, ordinances, rules, regulations,
orders or other requirements.
 
  4.17 Licenses and Permits. Each Company and Subsidiary has all material
governmental or regulatory licenses, permits and authorizations (all of which
are in full force and effect) reasonably necessary to conduct its business as
it is now being conducted, except for such governmental or regulatory
licenses, permits and authorizations the absence of which could not reasonably
be expected to have, individually or in the aggregate, a Company Material
Adverse Effect, and none of such governmental or regulatory licenses, permits
and authorizations will be impaired as a result of the transactions
contemplated by this Agreement, except in any case that could not reasonably
be expected to have, individually or in the aggregate, a Company Material
Adverse Effect. No Company or Subsidiary has received any notice to the effect
that, or otherwise been advised that, it is not in compliance with, or that it
is in violation of, any such governmental or regulatory licenses, permits and
authorizations in a manner that could reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect, and, to
the best knowledge of each Company and Subsidiary, there are no currently
existing circumstances that are likely to result in a failure of any Company
or Subsidiary to comply with, or in a violation by any Company or Subsidiary
of, any such governmental or regulatory licenses, permits or authorizations
that could reasonably be expected to have, individually or in the aggregate, a
Company Material Adverse Effect.
 
  4.18 Title to Assets. The Companies and the Subsidiaries have good and
marketable title to all of the owned tangible personal property used in the
conduct of their businesses, free and clear of all Encumbrances, except for
assets disposed of in the ordinary course of business. Each Company and each
Subsidiary has good and valid leasehold title to all leased tangible personal
property leased by it from third parties, free and clear of all Encumbrances,
except for imperfections which individually or in the aggregate could not
reasonably be expected to cause a Company Material Adverse Effect, and subject
to the rights of the lessor in and to such tangible personal property as is
subject to hire, leasing or rental agreements.

  from all payments made, or treated as made, to its employees or former
  employees, and in all material respects accounted to the Inland Revenue for
  all tax so deducted and for all tax chargeable on benefits provided for its
  Employees or former Employees.
 
    (f) Each Company and Subsidiary is not nor will it become liable in any
  material respect to pay or make reimbursement or indemnity in respect of
  any taxation (or amounts corresponding thereto) in consequence of the
  failure by any person (other than either Company or any Subsidiary (the

  nor are there circumstances under
 
                                      12

  Except as disclosed in the Letter of Disclosure delivered to the Companies

all requisite corporate power and authority to own, operate and lease its
properties and to carry on its business as it is now being conducted, and is
qualified or licensed to do business and is in good standing in each
jurisdiction in which the failure to be so qualified or licensed could
reasonably be expected, individually or in the aggregate, to have a material
and adverse effect upon the financial condition, prospects or results of
operations of Buyer or Buyer's Subsidiary (as defined below), considered as a
whole (a "Buyer Material Adverse Effect"). True and complete copies of the
Certificate of Incorporation and the By-Laws of Buyer have been delivered to
the Shareholders.

incorporation, with all
 
                                      16

 
requisite corporate power and authority to own, operate and lease its
properties and to carry on its business as it is now being conducted, and is
qualified or licensed to do business and is in good standing in each
jurisdiction in which the failure to be so qualified or licensed could

all Encumbrances. Except with respect to its ownership of Buyer's Subsidiary,
its ownership of the capital stock of PMT CVD Partners, Inc. and its limited
partnership interest in PMT CVD Partners, L.P., Buyer does not own, directly
or indirectly, any stock, partnership interest, joint venture interest or
other security, investment or interest in any other corporation, organization,
partnership, limited liability company or entity. As used in this Article V,
references to "Buyer" shall include Buyer's Subsidiary, except to the extent
the context requires otherwise.
 
  5.3 Capital Stock. The authorized capital stock of Buyer consists in its
entirety of Fifty Million (50,000,000) shares of Buyer's Common Stock, of
which, as of the date hereof, 8,692,065 are issued and outstanding, and Twenty

Disclosure Letter, there are no preemptive rights, registration rights,
subscriptions, options, warrants, rights, convertible securities or other
agreements or commitments of any character relating to the issued or unissued
capital stock or other securities of Buyer and there are no outstanding
contractual obligations of Buyer to repurchase, redeem or otherwise acquire or
sell, issue or otherwise transfer any shares of capital stock thereof.

issued as contemplated hereby at the Closing, will be validly issued, fully
paid and non-assessable, will not be subject to any preemptive or other
similar rights and will be delivered to each Shareholder free and clear of all
Encumbrances, and each Shareholder will acquire good and marketable title to
the Buyer Shares acquired by such Shareholder, subject to any transfer
restrictions pursuant to applicable securities laws. The Buyer Shares are
being issued pursuant to an available exemption from registration under the
Securities Act of 1933, as amended, provided by Regulation S promulgated
thereunder.
 
  5.5 Authority. Buyer has the full corporate power and authority to execute
and deliver this Agreement and each other agreement contemplated hereby, to
carry out its obligations hereunder and thereunder and to consummate the
transactions contemplated on its part hereby and thereby. The execution,
delivery and performance by Buyer of this Agreement and the consummation of
the transactions contemplated hereby have been duly authorized by its Board of
Directors. Upon approval by Buyer's shareholders of the issuance of the Buyer
Shares to the Shareholders pursuant hereto, no other action on the part of
Buyer will be necessary to authorize the execution and delivery of this
Agreement by Buyer or the performance by Buyer of its obligations hereunder.
This Agreement has been duly executed and delivered by Buyer, and is a legal,
valid and binding obligation of Buyer, enforceable against Buyer in accordance
with its terms, except to the extent that its enforceability may be limited by
applicable bankruptcy, insolvency, reorganization or other laws affecting
creditors' rights generally or by general equitable principles (regardless of
whether such enforceability is considered in a proceeding in equity or at
law). Each other agreement to be executed in connection with this Agreement on
or prior to the Closing Date will be duly executed and delivered by Buyer, and
will constitute a legal, valid and binding obligation of Buyer, enforceable
against it in accordance with its respective terms, subject to applicable
bankruptcy, insolvency, moratorium, reorganization, or similar laws affecting
creditors' rights generally and subject to general equitable principles
(regardless of whether such enforceability is considered in a proceeding in
equity or at law).
 
  5.6 No Violations or Consents. The execution, delivery and performance of
this Agreement by Buyer and the consummation by it of the transactions
contemplated hereby will not (a) violate or conflict with any provision of any
law specifically applicable to Buyer or by which any property or asset of it
is bound, (b) require the
 
                                      17

right of termination, amendment, acceleration or cancellation of, or result in
the creation of any Encumbrance on any property or asset of Buyer pursuant to
any provision of any charter or by-law, indenture, mortgage, lien, lease,
agreement, contract, instrument, order, judgment, ordinance, regulation or
decree to which Buyer is subject or by which Buyer or any of its property or
assets is bound, or (d) result in a loss or adverse modification of any
license, permit, certificate, franchise or contract granted to or otherwise
held by Buyer which, in any such case described in clauses (a) through (d),
could reasonably be expected to have, individually or in the aggregate, a
Buyer Material Adverse Effect.
 
  5.7 Financial Statements and Reports. Buyer heretofore has delivered to each
Company true and complete copies of (a) the Company's Registration Statement
on Form S-1 (the "Registration Statement") as declared effective by the

to in this Agreement as the "SEC Filings." As of the respective times such
documents were filed with the Commission, the SEC Filings complied as to form
and content, in all material respects, with the requirements of the Securities
Act and the Exchange Act, as the case may be, and the rules and regulations
promulgated thereunder, and did not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading. The financial statements of Buyer
included in the SEC Filings ("Buyer's Financial Statements") were prepared in
accordance with generally accepted accounting principles ("GAAP"),
consistently applied, and (except as may be indicated therein or in the notes
thereto) present fairly the consolidated financial position, results of
operations and cash flows of Buyer as of the dates and for the periods
indicated (subject, in the case of unaudited interim consolidated financial

incurred in the ordinary course of business subsequent to March 31, 1996, (ii)
obligations under real and personal property leases disclosed in Buyer's

merger, consolidation or other business combination, or for the acquisition of
a substantial portion of the assets of any Company or Subsidiary (an
"Acquisition Proposal"). The Company and each Shareholder agree to immediately
communicate to the Buyer the identity of such other party and the initial

  6.4 Proxy Statement and Meeting of Buyer's Shareholders.
 
    (a) As soon as reasonably practicable following the date hereof, Buyer
  shall prepare and file with the Commission, and, within ten (10) business
  days following clearance with the Commission, mail to its shareholders the
  Proxy Statement with respect to a meeting of Buyer's shareholders to
  consider and vote,
 
                                      25

 
  among other things, upon this Agreement and the transactions contemplated
  hereby, including without limitation, Buyer's purchase of the US Shares and
  ET Shares and the issuance of the Buyer Shares in connection therewith.
  Each Company, Subsidiary and Shareholder agrees to assist and cooperate
  with the Buyer in the preparation of the Proxy Statement with respect to
  information therein concerning any such Company, Subsidiary or Shareholder.
 
    (b) The Buyer, on the one hand, and each Company and Subsidiary and the
  Majority Shareholder, on the other hand, hereby represents, warrants and
  agrees with the other that the Proxy Statement will not, at the time the
  Proxy Statement is mailed, and at the date of the meeting of the
  shareholders of the Buyer held to approve the matters described therein,
  contain any untrue statement of a material fact or omit to state any
  material fact required to be stated therein or necessary to make the
  statements therein, in light of the circumstances under which they are
  made, not misleading, or to correct any statement made in any earlier
  communication with respect to the solicitation of any proxy or approval of
  the transactions contemplated by this Agreement in connection with which
  the Proxy Statement shall be mailed, except that no representation or
  warranty is being made by either with respect to information supplied by
  the other for inclusion in the Proxy Statement. The Buyer further
  represents, warrants and agrees that the Proxy Statement will comply as to
  form in all material respects with the provisions of the Exchange Act. The
  letter to shareholders, notice of meeting, proxy statement and form of
  proxy, or any information statement filed under the Exchange Act, as the
  case may be, that may be provided to shareholders of the Buyer in
  connection with the transactions contemplated by this Agreement (including
  any supplements), and any schedules required to be filed with the
  Commission in connection therewith, as from time to time amended or
  supplemented, are collectively referred to as the "Proxy Statement."
 
    (c) Buyer shall take all actions necessary in accordance with the
  California Corporations Code and the bylaws of Buyer to duly call, give
  notice of, convene and hold a meeting of its shareholders within forty-five
  (45) calendar days after the mailing of the Proxy Statement to approve the
  transactions contemplated by this Agreement.
 
  6.5 Indemnification by Buyer.
 
    (a) Buyer agrees, upon and subject to the occurrence of the Closing, to
  indemnify the Companies and the Shareholders against and hold the Companies
  and each Shareholder harmless from any and all claims, obligations, costs
  and expenses, including without limitation, reasonable attorneys' fees and
  expenses, and liabilities of and damages thereto arising out of the
  material breach of any representation, warranty, covenant or agreement of
  Buyer contained in Sections 5.3 (Capital Stock), 5.4 (Buyer Shares),
  5.5 (Authority) and 6.4(b) (Proxy Statement matters) hereof (the "Surviving
  Buyer Warranties"). Buyer agrees to similarly indemnify the Majority
  Shareholder and Nigel Wheeler against and hold them harmless from any such
  claims, obligations, costs and expenses arising by reason that either such
  person becomes an officer and/or director of Buyer upon or after the
  Closing and based upon any alleged act, omission or misconduct of Buyer, or
  its officers, directors or other agents, prior to the Closing to the same
  extent as all other officers and directors of Buyer.
 
    (b) The indemnified parties agree to give Buyer prompt written notice of
  any claim, assertion, event or proceeding by or in respect of a third party
  of which they have knowledge concerning any liability or damage as to which
  they may request indemnification hereunder, provided that the failure to
  give such notice shall not impair the rights of the indemnified parties
  hereunder or otherwise if and to the extent that the Buyer is not
  prejudiced thereby. Buyer shall have the right to direct, through counsel
  of its own choosing, the defense or settlement of any such claim or
  proceeding (provided that Buyer shall have first acknowledged its
  indemnification obligations hereunder specifically in respect of such claim
  or proceeding) at its own expense, which counsel shall be reasonably
  satisfactory to the indemnified party or parties. If Buyer elects to assume
  the defense of any such claim or proceeding, the indemnified party or
  parties may participate in such defense, but in such case the expenses of
  the indemnified party or parties incurred in connection with such
  participation shall be paid by the indemnified party or parties, unless (i)
  the indemnified party or parties have legal defenses available to them
  which are different than those available
 
                                      26

 
  to the indemnifying party such that representation by counsel of Buyer's
  choosing would be inappropriate, or (ii) the indemnifying party agrees to
  pay such expenses, then in either such case such expenses shall be paid by
  the indemnifying party. Such expenses shall be paid as and when incurred.
  The indemnified party or parties shall cooperate with Buyer in the defense
  or settlement of any such claim, assertion, event or proceeding. If Buyer
  elects to direct the defense of any such claim or proceeding, the
  indemnified party or parties shall not pay, or permit to be paid, any part
  of any claim or demand arising from such asserted liability, unless Buyer
  consents in writing to such payment or unless Buyer withdraws from the
  defense of such asserted liability, or unless a final judgment from which
  no appeal may be taken by or on behalf of Buyer is entered against such
  indemnified party for such liability. If Buyer shall fail to defend, or if,
  after commencing or undertaking any such defense, Buyer fails to prosecute
  or withdraws from such defense, the indemnified party or parties shall have
  the right to undertake the defense or settlement thereof at Buyer's
  expense.
 
  6.6 Indemnification by the Shareholders.
 
  (a) Each Shareholder agrees, severally and not jointly, upon and subject to
the occurrence of the Closing, to indemnify Buyer against and hold Buyer
harmless from any and all claims, obligations, costs and expenses, including
without limitation, reasonable attorneys' fees and expenses and liabilities of
and damages thereto arising out of any material breach of any representation,
warranty, covenant or agreement of such Shareholder contained in Article III
hereof and, with respect solely to the Majority Shareholder, Sections 4.3
(Share Capital; Title to ET Shares), 4.4 (Authority), and 6.4(b) (Proxy
Statement matters) hereof (the "Shareholder Surviving Warranties").
 
  (b) Buyer agrees to give the Shareholders prompt written notice of any
claim, assertion, event or proceeding by or in respect of a third party of
which it has knowledge concerning any Loss as to which it may request
indemnification hereunder, provided that the failure to give such notice shall
not impair the rights of the Buyer hereunder or otherwise to the extent that
the Shareholders are not prejudiced thereby. The Shareholders shall have the
right to direct, through counsel of their own choosing, the defense or
settlement of any such claim or proceeding (provided that the Shareholders
shall have first acknowledged their indemnification obligations hereunder
specifically in respect of such claim or proceeding) at their own expense,
which counsel shall be reasonably satisfactory to Buyer. If the Shareholders
elect to assume the defense of any such claim or proceeding, Buyer may
participate in such defense, but in such case the expenses of Buyer incurred
in connection with such participation shall be paid by Buyer, unless (i) the
indemnified party or parties have legal defenses available to them which are
different than those available to the indemnifying party such that
representation by counsel of Buyer's choosing would be inappropriate, or (ii)
the indemnifying party agrees to pay such expenses, then in either such case
such expenses shall be paid by the indemnifying party. Such expenses shall be
paid as and when incurred. Buyer shall cooperate with the Shareholders in the
defense or settlement of any such claim, assertion, event or proceeding. If
the Shareholders elect to direct the defense of any such claim or proceeding,
Buyer shall not pay, or permit to be paid, any part of any claim or demand
arising from such asserted Loss, unless the Shareholders consent in writing to
such payment or unless the Shareholders withdraw from the defense of such
asserted Loss, or unless a final judgment from which no appeal may be taken by
or on behalf of the Shareholders is entered against Buyer for such Loss. If
the Shareholders shall fail to defend, or if, after commencing or undertaking
any such defense, the Shareholders fail to prosecute or withdraws from such
defense, Buyer shall have the right to undertake the defense or settlement
thereof at the Shareholders' expense.
 
  6.7 General Indemnification Provisions. If the indemnifying party is
controlling the defense of a claim, the indemnifying party will not, without
the prior written consent of the indemnified party or parties, enter into any
settlement of such claim which could reasonably be expected to lead to
liability or create any financial or other obligation on the part of the
indemnified party or parties. If the indemnified party or parties are
controlling the defense of a claim, the indemnified party or parties will not
enter into any settlement of such claim without the consent of the
indemnifying party, which consent shall not be unreasonably withheld. The
indemnifying party shall advance amounts to the indemnified party or parties
then payable by the indemnifying party upon notice to the indemnifying party
and upon the indemnified party or parties entering into an agreement to repay
amounts
 
                                      27

 
advanced that it is ultimately determined not to be entitled to. The
controlling party shall deliver, or cause to be delivered, to the other party
or parties copies of all correspondence, pleadings, motions, briefs, appeals
or other written statements relating to or submitted in connection with the
defense of any such claim and timely notices of, and the right to participate
in (as observer), any hearing or other court proceeding relating to such
claim.
 
  6.8 Best Efforts. Upon the terms and subject to the conditions herein
provided, Buyer, each Company and each Shareholder agrees to use its
reasonable efforts to take, or cause to be taken, all action, and to do, or
cause to be done, all things necessary, proper or advisable to consummate the
transactions contemplated by this Agreement including (a) to lift or rescind
any injunction or restraining order or other order adversely affecting the
ability of the parties to consummate the transactions contemplated hereby and
(b) to fulfill all conditions on its part to be fulfilled under this
Agreement. In case at any time after the Closing Date any further action is
reasonably necessary or desirable to carry out the purposes of this Agreement,
the proper officers or directors of each party or the proper persons to this
Agreement shall take all such reasonably necessary action, including without
limitation, the delivery by each Shareholder to Buyer of a proxy to vote the
ET Shares in favor of this Agreement and the transactions contemplated hereby,
if so requested by Buyer. No party hereto will take any action for the purpose
of delaying, impairing or impeding the receipt of any required consent,
authorization, order or approval or the making of any required filing. Each
Company and Shareholder, on the one hand, and the Buyer, on the other hand,
shall give prompt notice to the other of (i) the occurrence, or failure to
occur, of any event which occurrence or failure would be likely to cause any
of its representations or warranties contained in this Agreement to be untrue
or inaccurate in any material respect any time from the date hereof to the
Closing Date and (ii) any material failure by it to comply with or satisfy any
covenant, condition or agreement to be complied with or satisfied by it
hereunder, and each shall use all reasonable efforts to remedy such failure.
In addition, each shall give prompt notice to the other of any material
developments involving its operations or activities.
 
  6.9 Consents. The Buyer, each Company and each Shareholder will use its
reasonable best efforts to obtain all necessary waivers, consents and
approvals of all third parties and governmental authorities necessary to the
consummation of the transactions contemplated by this Agreement.
 
  6.10 No Transfer. Each Shareholder agrees that such Shareholder will not,
directly or indirectly, transfer, sell, assign, pledge, hypothecate, encumber
or otherwise dispose of any shares of either Company's share capital which
such Shareholder owns on and after the date hereof; provided, however, that
any Shareholder may transfer a portion of such shares (subject to his rights
and obligations hereunder with respect to such shares) to one or more trusts
established for the benefit of members of his family or established for
charitable purposes, provided that such trusts become a party hereto and
become otherwise bound hereby with respect to such transferred shares. ETE
agrees that it will not, directly or indirectly, transfer, sell, assign,
pledge, hypothecate, encumber or otherwise dispose of any of the US Shares.
 
  6.11 Environmental Investigations. Buyer shall conduct such environmental
investigations and reviews with respect to the Real Properties of the
Companies, including without limitation, Phase I investigations, as it shall
deem appropriate, in its sole discretion.
 
  6.12 Delivery of Financial Statements and Other Documents. Until the Closing
Date, each Company, on the one hand, and the Buyer, on the other hand, shall
deliver to the other:
 
    (a) as soon as practicable, but in any event within thirty (30) days
  after the end of each month, and within forty-five (45) days after the end
  of each quarter (with respect to the first three quarters of the applicable
  fiscal year) and within 60 days after the end of the last fiscal quarter,
  its unaudited consolidated profit and loss account, consolidated balance
  sheet and consolidated cash flow statement for such month or quarter, as
  the case may be, and for the fiscal year-to-date. Buyer's independent
  accountants, Ernst & Young, shall have reviewed all quarterly financial
  statements submitted by Buyer in compliance with the foregoing covenant;
 
    (b) as soon as practicable, but in any event within five (5) days of its
  receipt thereof, copies of any management letters and other correspondence
  of its independent auditors;
 
                                      28

 
    (c) prompt notice of any material defaults under any material contracts
  and of any litigation;
 
    (d) monthly updates to the backlog descriptions described in Section 4.20
  and 5.19, as applicable. Each such update shall serve to supersede and
  replace in its entirety all previous backlog descriptions, provided that
  such updated descriptions shall, thereafter, be subject to the
  representations and warranties set forth in Sections 4.20 and 5.19, as
  applicable;
 
    (e) as soon as practicable, all other information requested by the other,
  where such information is readily available and may be reduced to written
  form.
 
  6.13 Additional Payments at Closing. The Buyer agrees that, upon the Closing
and the purchase of the ET Shares and US Shares by Buyer hereunder, the Buyer
shall pay to Christopher D. Dobson the cash amount of US$500,000 pursuant to
the Noncompetition Agreement (the "Dobson Noncompetition Fee") and shall
deliver to the Companies (in such respective amounts as the Majority
Shareholder shall direct) the following aggregate amounts and property as
contributions to capital:
 
    (a) at the discretion of the Board of Directors of ET and ETE, the cash
  sum of approximately US$1,500,000, the precise amount of which shall be
  specified by the Majority Shareholder prior to the Closing as the amount
  which, when added to the cash amount paid by Buyer for the US Shares, as
  specified in Section 1.3, represents the U.S. Dollar equivalent (the
  "Employee Bonus Amount") of One Pound Sterling for each day that all
  employees of the Companies and the Subsidiaries as of the Closing shall
  have been continuously employed by such Company or Subsidiary, as
  applicable, as of the Closing (such that the price paid for the US Shares,
  together with the capital contribution pursuant to this clause (a), shall
  be equal to the Employee Bonus Amount);
 
    (b) a cash amount, the precise amount of which shall be specified by the
  Majority Shareholder prior to the Closing, calculated to result in an
  after-tax bonus payment (assuming the highest marginal income tax rates) to
  Nigel Wheeler of approximately Six Hundred Thousand Dollars (US$600,000)
  (such full pre-tax amount being referred to as the "Wheeler Bonus"), it
  being understood and agreed that Mr. Wheeler will take all appropriate
  action to minimize his actual income tax obligations in respect of the
  Wheeler Bonus and that the actual after-tax portion of such bonus may
  accordingly exceed US$600,000; and
 
    (c) the cash sum of US$7,000,000 (the "Dobson Negotiation Fee").
 
    The Companies agree to pay or deliver, or cause the Subsidiaries to pay
  or deliver, the following aggregate sums or consideration (subject to any
  applicable withholdings required by law) to the indicated persons at the
  indicated times.
 
      (i) to each employee of any Company or Subsidiary as of the Closing,
    a bonus for past services rendered in an amount equal to One Pound
    Sterling for each day that such employee shall have been continuously
    employed by such Company or Subsidiary, as applicable, as of the
    Closing, to be paid as soon as practicable after the Closing;
 
      (ii) to Nigel Wheeler for past services rendered, the Wheeler Bonus,
    to be paid at the Closing; and
 
      (iii) to Christopher D. Dobson, the Dobson Negotiation Fee, to be
    paid at the Closing.
 
  6.14 Company Employee Benefits and Stock Options.
 
    (a) At and following the Closing, the Buyer shall cause the Companies and
  Subsidiaries to, from and after the Closing, honor in accordance with their
  terms all existing employment arrangements with their respective directors,
  other officers and Employees, provided that such arrangements have been
  disclosed in accordance with the terms of this Agreement. Furthermore, the
  Buyer represents and warrants that it presently intends to cause the
  Companies and Subsidiaries to continue indefinitely to provide pension and
  welfare benefits to their Employees (considered as a group) which benefits
  are intended to be in the aggregate no less favorable than those currently
  provided by the Companies and Subsidiaries in the aggregate to such
  Employees. Nothing set forth above in this Section shall be deemed to
  constitute an amendment of any existing employee benefit plan, program or
  arrangement or to prevent the Buyer or any Company or any Subsidiary from
  making any change in any plan, program or arrangement, including any change
  required by law or deemed necessary or appropriate to comply with
  applicable law or regulation.
 
                                      29

 
    (b) Sufficiently prior to the Closing to facilitate the satisfaction of
  the condition to Closing set forth in Section 7.2(f), the Buyer shall
  recommend to its Board of Directors and Compensation Committee thereof the
  grant, under the Buyer's Stock Option Plan, of options covering an
  aggregate of approximately 800,000 shares of Buyer's Common Stock to such
  employees of the Companies and Subsidiaries, and in such respective
  individual amounts, as shall be jointly determined by the Buyer and the
  Majority Shareholder prior to the Closing. Such recommended option grants
  shall otherwise be at prices and upon such terms as are customarily
  contained in options generally granted under the Stock Option Plan.
 
  6.15 Use of Company Information. Buyer agrees that it shall not file with
the Securities and Exchange Commission of the United States any disclosure
document, including but not limited to the Proxy Statement, any document
relating to the financing referred to in Section 7.3(g), any report or other
document filed by the Buyer under the Exchange Act or otherwise made public,
that includes the names of either of the Companies, the Shareholders or any
Affiliate or Associate thereof, without the prior written consent of the
Majority Shareholder, except solely as and to the extent that the Buyer is
advised by its legal counsel that the same is required by law to be so filed
(in which case the Buyer shall use its best efforts to provide to the Majority
Shareholder, as early as possible prior to such filing, a copy of the document
proposed to be so filed, and shall give the Majority Shareholder, as and to
the extent practicable, reasonable opportunity to review and reasonably modify
such proposed filing).

  8.3 Effect of Termination. Except as otherwise provided in Section 8.2, in
the event of the termination of this Agreement as provided in Section 8.1
above, this Agreement shall forthwith become void and there shall be no
liability on the part of any party hereto, provided that nothing in this
Section 8.3 shall relieve any party of liability for any intentional breach of
the purchase and sale covenants herein, or the covenant to use reasonable
efforts to satisfy all conditions to Closing, which breach results in a
termination of this Agreement. Notwithstanding the foregoing, the covenant set
forth in Section 8.6 shall survive any termination of this Agreement for a
period of one year.
 
  8.4 Amendment. This Agreement may not be amended except by an instrument in
writing signed on behalf of each of the parties hereto.
 
  8.5 Waiver. At any time prior to the Closing Date, the parties hereto may
(a) extend the time for the performance of any of the obligations or other
acts of the other parties hereto, (b) waive any inaccuracies in the
representations and warranties contained herein or in any document delivered
pursuant hereto and (c) waive compliance with any of the agreements or
conditions herein, provided that any such waiver of or failure to insist on
strict compliance with any such representation, warranty, agreement or
condition shall not operate as a waiver of, or estoppel with respect to, any
subsequent or other failure. Any agreement on the part of a party hereto to
any such extension or waiver shall be valid only if set forth in an instrument
in writing signed on behalf of such party.
 
  8.6 Conduct Following Termination. Following any termination of this
Agreement, neither Buyer nor its representatives, on the one hand, nor any
Company or Subsidiary nor any of their respective representatives nor the
Shareholders, on the other hand, shall publicly state any disparaging or
similar remark regarding the other.

the best of its knowledge" or any substantially equivalent phrase is used in
this Agreement with respect to the representations and warranties of any
Company, Subsidiary or Shareholder, on the one hand, or the Buyer, on the
other hand, it shall mean both the actual knowledge of any such individual
person and, in the case of a corporation, the actual knowledge of each
executive officer thereof (including specifically the Majority Shareholder
with respect to each Company), and such knowledge as any such person, director
or officer could reasonably be expected to acquire in the course of reasonable
inquiry and investigation of the matters with respect to which such
representation and warranty is made.

  9.6 Entire Agreement. This Agreement, the Letter Agreement dated May 2, 1996
and the Mutual Non-Disclosure Agreement dated December 19, 1995, as amended by
that certain letter dated May 22, 1996 to ET's counsel from counsel to the
Buyer, constitute the entire agreement among the parties and supersede all
other prior agreements and understandings, both written and oral, among the

  9.7 Conveyance Taxes. The Buyer agrees to assume liability for and to hold
the Shareholders harmless against any sales, use, transfer, stamp, stock
transfer, real property transfer or gains, and value added taxes, any
transfer, registration, recording or other fees (including without limitation,
any stamp duties), and any similar taxes incurred as a result of the
transactions contemplated hereby, other than capital gains taxes imposed upon
the Shareholders by virtue of the disposal of the ET Shares or with respect to
a higher rate of taxes due on any pre-Closing dividends due by reason of the
transactions permitted by Section 9.8 hereof, as to which the Shareholders
agree severally and not jointly to assume liability for and to hold Buyer and
the Companies harmless against.
 
  9.8 Company Pre-Closing Dividends. The Companies may, prior to the Closing,
declare and pay cash dividends to the Shareholders up to an amount permitted
by law but not exceeding the net cash payment specified in Section 1.4(a)
hereof, in which case the parties agree that:
 
  (a) Buyer shall, immediately prior to the Closing, loan to the Companies an
amount equal to the sum of such dividends, plus all taxes required to be paid
by the Companies in connection with the payment of such dividends (the
"Dividend Taxes"), in order to fund the payment of such dividends immediately
prior to the Closing and the payment of the Dividend Taxes;
 
  (b) The cash portion of the Purchase Price payable to the Shareholders at
the Closing pursuant to Section 1.4 shall be reduced, prorata as to each
Shareholder, by an aggregate amount equal to such loan by the Buyer;
 
  (c) Immediately after the Closing, the indebtedness of the Companies to the
Buyer in respect of the loan referred to in clause (a) shall be forgiven by
the Buyer as a contribution to the capital of the Companies but subject to the
contingent obligation of the Companies to make the payments described in
clause (d) below; and
 
  (d) From time to time if and when the Companies are entitled to a credit for
the Dividend Taxes against other amounts due and payable for income taxes of
the Companies, then the Companies shall pay to the Shareholders (promptly
after such time as the Companies would have otherwise been required to pay to
the taxing authorities the amounts so reduced by such credit), prorata to each
Shareholder in the same proportion that the cash portion of the Purchase Price
was reduced under clause (b) above, the aggregate amount of such credit.
 
  9.9 Advance of Reimbursable Expenses. Within seven (7) days after
presentation to the Buyer by the Companies of invoices or other reasonable
evidence thereof, the Buyer shall advance to the Companies a sum equal to all
Reimbursable Expenses incurred by the Companies prior to the execution of this
Agreement in respect of amounts payable to third parties other than Hambrecht
& Quist, and excluding any internal charges or expenses of the Companies or
any Subsidiary. Such payments shall be considered an advance in respect of any
amounts ultimately owed by the Buyer to the Companies pursuant to Section 8.2
hereof and, if no amounts are ever owed by the Buyer to the Companies pursuant
to Section 8.2 hereof by reason of the occurrence of a No-Fee Termination of
this Agreement, the Companies shall, within seven (7) days following the
occurrence of such No-Fee Termination, refund to the Buyer all amounts
advanced to the Companies pursuant to this Section 9.9.
 
  9.10 Hold-back Agreement. Each of the Shareholders severally agrees that
such Shareholder will not offer, sell or contract to sell, or otherwise
dispose of, directly or indirectly, or announce an offering of any shares of
Buyer Common Stock beneficially owned by such Shareholder or any securities
convertible into, or exchangeable for, shares of Buyer Common Stock for a
period of 90 days following the Closing Date, without the prior written
consent of Salomon Brothers Inc, the lead investment banker engaged by the
Buyer in connection with the transaction described in Section 7.3(g).
