Teltrend Inc. (the "Company" or "Registrant") submits the following information:

ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

        On September 18, 1997 (the "Closing Date"), the Company consummated the
purchase of all the outstanding shares (the "Shares") in the capital of
Securicor 3 Net Limited of Basingstoke, England and its U.S. affiliate
Securicor 3Net Inc. (collectively, "3Net") from 3 Net Holdings Limited of
Surrey, England ("3Net Holdings").  3Net Holdings is a subsidiary of Securicor
Communications Limited of Surrey, England ("Securicor Communications").  With
operations in England, New Zealand, China and the United States, 3Net is a
leading developer of Integrated Services Digital Network ("ISDN") products for
communications equipment and service providers.  3Net also supplies LAN
internetworking, ISDN Remote Access and secure Virtual Private Networking
solutions for business customers worldwide.  The Company believes 3Net will
help it to expand into foreign markets and will allow the Company to deliver
ISDN products for the infrastructure and terminal equipment markets.

        Pursuant to a Share Purchase Agreement, dated August 28, 1997, 
negotiated and entered into among the Company, Securicor 3 Net Limited, 3 Net
Holdings, Securicor Communications and Security Services plc (the parent
company of 3Net Holdings and Securicor Communications), the Company acquired
all of the Shares for U.S. $14,445,000 in cash paid on the Closing Date.  3Net
will adopt Teltrend's name and identity, but the Company does not expect any
redundancies or major organization changes due to the acquisition. The Company
funded its acquisition of 3Net with its cash and cash equivalents on hand and
the proceeds from the sale of certain of its investments in debt securities.

ITEM 7. FINANCIAL STATEMENTS.  Pro Forma Financial Information and Exhibits.

        (a) Financial Statements of Businesses Acquired.  The financial 
statements of the business acquired required by Item 7 of Form 8-K shall be 
filed on or about December 1, 1997, as an amendment to this report.

        (b) Pro Forma Financial Information.  The pro forma financial 
information with respect to the business acquired required by Item 7 of 
Form 8-K shall be filed on or about December 1, 1997, as an amendment to this 
report.

conditions set forth herein, at the Closing 3Net Holdings shall (and the other
Sellers shall cause it to) sell and transfer with full title guarantee to
Teltrend, and Teltrend shall purchase from 3Net Holdings, all of the Shares,
free and clear of any Encumbrances and together with all rights now or

         2.2 PURCHASE PRICE AND ADJUSTMENT.

         (a) PURCHASE PRICE. The aggregate purchase price to be paid for the
Shares (the "PURCHASE PRICE") shall be pound sterling 9,000,000, payable in 
dollars at the Closing (the amount of such dollar payment to be determined by 
applying the Closing Exchange Rate to pound sterling 9,000,000); provided, 
however, that (i) if the Closing Exchange Rate is greater than $1.722 per 
pound, the Purchase Price shall nonetheless be $15,498,000, and (ii) if the 
Closing Exchange Rate is less than $1.558 per pound, the Purchase Price shall

and reflecting the application of the Pro Forma Adjustments to the Closing
Balance Sheet (to the extent they affect the Closing Balance Sheet), the
amounts of which shall be determined as of the Closing. The

<PAGE>   23



Closing Balance Sheet shall be accompanied by an opinion (the "ERNST & YOUNG
CLOSING OPINION") of Ernst & Young, Chartered Accountants ("ERNST & YOUNG"),
to the effect that such firm has audited the Closing Balance Sheet in
accordance with generally accepted auditing standards in the United Kingdom
and that the Closing Balance Sheet has been prepared in accordance with GAAP,
consistently applied, and gives a true and fair view of the combined financial
position of the Company and the Subsidiaries as at the Closing in accordance
with GAAP. The expenses of Ernst & Young in connection with their audit of the
Closing Balance Sheet and preparation of the Pro Forma Closing Balance Sheet
shall be shared equally by Teltrend, on the one hand, and Sellers, on the
other hand.

         (c) REVIEW OF AND RESOLUTION OF DISPUTES RELATING TO CLOSING AND PRO
FORMA CLOSING BALANCE SHEETS. Sellers and their accountants shall complete
their review of the Closing Balance Sheet and Pro Forma Closing Balance
Sheet within 30 days after the later of (i) the date on which the Pro
Forma Closing Balance Sheet, Closing Balance Sheet and the Ernst & Young
Closing Opinion are delivered to Sellers, and (ii) the date on which the
Ernst & Young work papers supporting the Closing Balance Sheet and Pro
Forma Closing Balance Sheet are first made available to Sellers and their
accountants. In the event that Sellers determine that any item reflected
on the Pro Forma Closing Balance Sheet has not been determined on the
basis set forth in this Agreement, Sellers shall so inform Teltrend in
writing (the "OBJECTION"), on or before the last day of such 30-day
period, setting forth a specific description of the basis or bases of the
Objection and the adjustments to the Pro Forma Closing Balance Sheet which
Sellers believe should be made. Teltrend shall have 30 days after its
receipt of the Objection to review and respond to the Objection and the
parties shall attempt in good faith to reach an agreement with respect to
any matters in dispute. If Sellers and Teltrend are unable to resolve all
of their differences within 45 days after delivery of the Objection, they
shall refer their remaining differences to an internationally recognized
firm of independent chartered accountants as to which Sellers and Teltrend
shall mutually agree or, in the event that they are unable so to agree, to
such a firm to be selected by the President for the time being of the
Institute of Chartered Accountants in England and Wales (the "CPA FIRM").
the CPA Firm shall, acting as binding experts and not as arbitrators,
determine, on the basis of the standards set forth in this Agreement, and
only with respect to the remaining differences so submitted, whether and
to what extent, if any, the items reflected on the Pro Forma Closing
Balance Sheet require adjustment. The CPA Firm's determination shall be
conclusive and binding upon Sellers and Teltrend and shall be set forth in
a written determination of the CPA Firm. The fees and disbursements of the
CPA Firm shall be shared equally by Sellers, on the one hand, and
Teltrend, on the other hand. Teltrend and Sellers shall each make readily
available to the CPA Firm all relevant books and records and any work
papers (including those of their respective accountants) relating to the
Balance Sheet, Pro Forma Closing Balance Sheet and Closing Balance Sheet,
and all other items reasonably requested by the CPA Firm. As used herein,
the term "FINAL PRO FORMA CLOSING BALANCE SHEET" means (i) the Pro Forma
Closing Balance Sheet in the event that no Objection is delivered to
Sellers during the 30-day period specified above, (ii) the Pro Forma
Closing Balance Sheet, adjusted in accordance with the Objection in the
event that Teltrend does not respond to the Objection within the 30-day
period



                                     17



<PAGE>   24



following receipt by Teltrend of the Objection, (iii) the Pro Forma Closing
Balance Sheet, as adjusted by the mutual agreement of Sellers and Teltrend, or
(iv) the Pro Forma Closing Balance Sheet as determined by the CPA Firm in
accordance with the terms hereof if Sellers and Teltrend are unable to reach
any mutual agreement regarding their differences concerning the Pro Forma
Closing Balance Sheet and, pursuant to the terms of this SECTION 2.2(C), refer
their remaining differences to the CPA Firm.

         (d) Access TO INFORMATION AND PARTICIPATION IN AUDIT. Sellers shall, to
the extent they remain in possession or control thereof at or after the
Closing Date, provide (or cause to be provided) to Teltrend and its
accountants all Books and Records and any other information or data relating
to the pre-Closing operation of the Business and shall otherwise reasonably
cooperate with Teltrend and, to the extent necessary for Teltrend's
preparation of the Closing Balance Sheet and Pro Forma Closing Balance Sheet,
grant Teltrend access to their personnel familiar with the pre-Closing
operation of the Business. Teltrend shall provide Sellers and their
accountants reasonable access to the Books and Records and any other
information relating to the pre-Closing operation of the Business in
accordance with SECTION 5.14(b) hereof to the extent necessary for Sellers and
their accountants to review the Closing Balance Sheet and Pro Forma Closing
Balance Sheet. In connection with their review of the Closing Balance Sheet
and Pro Forma Closing Balance Sheet, Sellers and their accountants shall have
full access to all information used by Ernst & Young and/or Teltrend in
preparing or causing to be prepared the Closing Balance Sheet and Pro Forma
Closing Balance Sheet. Upon completion of the audit by Ernst & Young of the
Closing Balance Sheet and preparation of the Pro Forma Closing Balance Sheet,
Sellers and their accountants shall have the opportunity to review Ernst &
Young's work papers and to discuss proposed adjustments and other matters
related to the audit with Ernst & Young.

         (e) PURCHASE PRICE ADJUSTMENT. The Purchase Price shall be adjusted on
a pound-for-pound basis (the "ADJUSTMENT") to the extent that the "Net Assets"
reflected on the Final Pro Forma Closing Balance Sheet have decreased by more
than pound sterling 100,000 from the amount of "Net Assets" reflected on the 
Pro Forma Balance Sheet. Sellers shall pay to Teltrend within five Business Days
following the determination of the Final Pro Forma Closing Balance Sheet an
amount in cash equal to the Adjustment, if any, plus interest thereon from the
date of delivery of the Ernst & Young Closing Opinion to the date of payment at
an annual rate equal to the London Interbank Offer Rate in effect on the
Closing Date as reflected in The Financial Times ("LIBOR"), by wire transfer
of immediately available funds to an account or accounts designated by
Teltrend; provided, however, that if such payment is not made within the
aforesaid five Business Days, interest thereon shall accrue thereafter at an
annual rate equal to LIBOR plus 100 basis points to the date of payment. The
Adjustment and interest payment shall be payable in dollars, the amount of
such dollar payment to be determined by applying the Closing Exchange Rate to
the amount of the Adjustment and interest payment as denominated in pounds.

(including the Business) as now being and as heretofore been conducted. 3Net
Delaware is duly qualified to do business and is in good standing as a foreign
corporation in the State of New Jersey, and there are no other foreign
jurisdictions in which the conduct of its business or activities or its
ownership of assets as currently carried out requires any other qualification

Subsidiary is pending or threatened, and no corporate action in view of any
such transaction or arrangement has been taken. Neither the Company nor any of
the Subsidiaries has stopped payment to its creditors, is unable to pay its

each Subsidiary, any amendment to the memorandum or articles of association,
certificate of incorporation, bylaws, constitution or other governing
documents of the Company and each Subsidiary and the passing of resolutions

not entered into any transaction ultra vires the Company or such Subsidiary,
as applicable, or outside of the authority or powers of the directors of the
Company or such Subsidiary, as applicable, and has at all times operated in
accordance with the provisions of its governing documents. Except as set forth
on SCHEDULE 3.7 to the Disclosure Memorandum, the statutory and minute books
of the Company and each Subsidiary have been properly kept and contain an
accurate and complete record of the matters which should be dealt with in
those books and no notice or allegation that any of them is incorrect or
should be rectified has been received.

     3.8 CAPITALIZATION OF COMPANY AND SUBSIDIARIES. SCHEDULE 3.8 to the
Disclosure Memorandum sets forth the entire authorized share capital or
capital stock (or other form of ownership interest, in the case of 3Net China)
of the Company and each Subsidiary, indicating in each case which shares in
the capital or of capital stock (or other form of ownership interest, in the
case of 3Net China) are issued (allotted) and the owners thereof. Neither the
Company nor any Subsidiary has any direct or indirect equity or other
ownership interest in any corporation, company, joint venture, partnership,
business association, entity, enterprise or other Person other than another

such issued shares in the capital or of capital stock (or other ownership
interests)

                     a true and complete list of (A) all real property used or
                     occupied by the Company or any Subsidiary or otherwise in

                     letter agreements and assignments relating thereto (the

              (ii)   Each Lease is legal, valid, binding and enforceable, and
                     in full force and effect. Neither the Company nor any
                     Subsidiary and, to the best knowledge of the Sellers, no
                     other party is in default, breach or violation in any

                     Lease, and no event, to the best knowledge of Sellers, has
                     occurred and is continuing that constitutes, or with
                     notice and/or the passage of time would constitute, a
                     default, violation or breach in any respect under any
                     Lease or any lease superior to such Lease; provided,
                     however, that any warranties relating to any lease
                     superior to the Leases of the Leased Real Property shall
                     only be so far as the Sellers are liable to perform any
                     obligations in such superior lease under the terms of the
                     Leases of the Leased Real Property or so far as the
                     Sellers have been given notice that there has been any
                     default, breach or violation of any of the terms of any    
                     leases superior to the Leases of the Leased Real Property.

              (iii)  Each Lease grants the tenant under the Lease the exclusive
                     right to use and occupy the demised premises thereunder.
                     The Company and each Subsidiary has good and valid title
                     to the leasehold estate under each Lease to which it is a
                     party, free and clear of all Encumbrances other than
                     Permitted Encumbrances. The Company and each       
                     Subsidiary enjoys peaceful and undisturbed possession
                     under its respective Leases of the Leased Real Property.

              (iv)   There are no forfeiture or other similar proceedings 
                     pending or, to the best knowledge of Sellers, threatened 
                     affecting any portion of the Leased Real Property. There 
                     is no writ, injunction, decree, order, award, ruling, 
                     stipulation or judgment outstanding, nor any action,

                     claim, suit or proceeding pending or, to the best
                     knowledge of the Sellers, threatened relating to the
                     ownership, lease, use, occupancy or operation by any
                     Person of any Leased Real Property; provided, however,
                     that this warranty is given on the basis that the Sellers
                     have not been notified of any such matters relating to any
                     lease superior to the Leases of the Leased Real Property,
                     have made no specific enquiry relating to such matters 
                     affecting any such superior lease and shall not be obliged
                     to make any such enquiry.

              (v)    Except as set forth on SCHEDULE 3.16(a)(v) to the 
                     Disclosure Memorandum, the use and operation of the Leased 
                     Real Property in the conduct of the Business does not
                     violate in any Material respect any agreement to or of
                     which the Company, any Subsidiary or any of their
                     Affiliates is a party or is aware affecting the Leased
                     Real Property. To the best knowledge of Sellers, there are
                     no matters affecting the Leased Real Property which might
                     curtail or interfere with the use of the Leased Real

result in any such assessment.

     (b) The Company and each Subsidiary has paid (or Sellers or Sellers'

     3.26   MATERIAL CONTRACTS. SCHEDULE 3.26(a) to the Disclosure Memorandum
contains a true and complete list of all Contracts (such Contracts, or those
which should have been listed on SCHEDULE 3.26(a), are the "MATERIAL

of Business and contracts terminable by the Company or a Subsidiary on 30
days' notice or less without penalty.

     Each Material Contract is a valid and binding obligation of the Company
or the Subsidiary party thereto, and, to the best knowledge of the Sellers,
each other party thereto, enforceable against each of them in accordance with
its terms, and is in full force and effect. The Company and each Subsidiary
has performed all obligations required to be performed by it under each
Material Contract to which it is a party and neither the Company nor any
Subsidiary nor, to the knowledge of the Sellers, any other party to any
Material Contract, is (with or without the lapse of time or the giving of
notice, or both) in breach or default in any Material respect thereunder and
there exists no condition which, to the knowledge of the Sellers, would
constitute a breach or default thereunder. Neither the Company, the Sellers
nor any Subsidiary has been notified or is aware that any party to any
Material Contract intends to cancel, terminate, not renew or exercise an
option under any Material Contract, whether in connection with the
transactions contemplated hereby or otherwise.

     None of the Sellers, the Company or the Subsidiaries has released any of
its rights under any Material Contract. No Contract requires from the Company
or any Subsidiary the payment or performance of material obligations on or
after the Closing Date without receipt by such company of consideration of
commensurate value on or after the Closing Date. No advance payments have been
made under any Material Contract. No Material Contract is currently of a
loss-making nature after taking into account costs directly allocable thereto.
There has been no offer given or made by the Company or any Subsidiary on or
before the date of this Agreement and still outstanding which is capable of
giving rise to a Material Contract merely by the unilateral act of another
Person. Except as set forth on SCHEDULE 3.15(c)(ii) to the Disclosure
Memorandum, no amounts shall become payable and no benefits shall accrue to
any Person under any Contract as a result of the execution of this Agreement
or any Ancillary Agreement and the consummation of the transactions
contemplated hereby and thereby. None of the Company or the Subsidiaries is or
has been party to any agreement (as defined in the RTPA) which has been
furnished to the Director General of Fair Trading as provided for in the RTPA
or which was subject to registration under the RTPA and has not been so
furnished. There is no pending warranty claim against any member of the 3Net
Group, other than claims the burden of which the relevant member of the 3Net
Group is able to pass on to the manufacturer of the product in question, nor
is there any basis for any such claim to be asserted.

     3.27  U.K. PENSION SCHEMES.

     (a)   The Pension Schemes are the only retirement benefit schemes (as
defined in Section 611 of ICTA) in which any U.K. Company participates for the
purpose of providing relevant benefits (as defined in Section 612(1) of ICTA)
to or in respect of the employees of any U.K. Company. Other than pursuant to
the Pension Schemes, there are no legal or moral obligations to pay any
pension, gratuity, superannuation allowance, death benefit, retirement
gratuity or like benefit or make any other payment after disability,
retirement or death or contribute to any life assurance in respect of any
current or former employee of any U.K. Company.

     (b)   The Pension Schemes are approved as exempt approved schemes (within
the meaning of Chapter I of Part XIV of ICTA) and the Sellers are not aware of
any reason why the Inland Revenue might withdraw or vary such approval.

     (c)   True and complete copies of all documents establishing and comprising
the Pension Schemes and full particulars of the benefit entitlements under the
Pension Schemes have been delivered to Teltrend as well as a list of the
employees of the Company who participate in the Securicor Scheme and a list of
employees and former employees of each U.K. Company who participate in the
Save and Prosper Scheme and there is no obligation to provide benefits under
the Pension Schemes other than is revealed in such documents and particulars.

     (d)   There are no claims against the trustees or administrators of the
Pension Schemes or any U.K. Company arising out of or in connection with the
Pension Schemes save for the routine payment of benefits.

     (e)   The Company has paid to the trustees of the Save and Prosper Scheme
all contributions due and payable under the Save and Prosper Scheme.

     (f)   The Save and Prosper Scheme is a fully insured paid up scheme with
Save & Prosper Group Limited.

accordance with the contribution rates recommended by the Actuary to the
Securicor Scheme and a true and complete copy of the last actuarial valuation
report and of the latest accounts relating to the Securicor Scheme has been
delivered to Teltrend. The Securicor Scheme has sufficient assets to meet its
current liabilities to its beneficiaries on the basis used in the last
actuarial valuation. No circumstances or events have occurred since the last
actuarial valuation that rendered any U.K. Company liable to pay increased
contributions to the Securicor Scheme.

     (b)

     (i)   All contributions required to be made under the terms of any 
Employee Benefit Plan have been timely made.

     (ii)  The Company and each Subsidiary has made all required contributions

specified benefits) with respect to all employees and former employees of the
Company and the Subsidiaries and Prior Subsidiaries, whether managed by
governmental or quasi-governmental entities or otherwise, other than
contributions not yet payable for which (A) all provisions (reserves) required
in accordance with GAAP have been made in the Balance Sheet, and (B) as of the
Closing Date all provisions (reserves) required in accordance with GAAP shall 
have been made in the Closing Balance Sheet.

employees) with respect to all employees and former employees of the Company
and the Subsidiaries and Prior Subsidiaries, either (A) by transfers of
sufficient funds to reputable insurance companies or other independent
organizations which have undertaken to pay all such pensions, retirement
benefits or indemnities (and to assume all financial and actuarial risks
involved therewith), or (B) or through contributions to trusts or similar
funds.  To the extent that any such plan is funded through contributions to a 
trust or similar entity, the actuarial present value, determined in accordance 
with the actuarial assumptions specified for accounting purposes in such plan's
most recent actuarial valuation report, of the accumulated plan benefit 
obligations does not exceed the amount of the fair market value of the assets 
of such trust or similar fund.

     (c)   Each Employee Benefit Plan which is intended to be qualified under
Section 401(a) of the U.S. Code has received a favorable determination letter

Sellers, there are no circumstances likely to result in revocation of any
such favorable determination letter.

<PAGE>   64


Disclosure Memorandum (or in any other Ancillary Agreement if it were executed
at Closing) shall continue to be true and correct in all material respects on
and as of the Closing as if made on and as of the Closing, and shall promptly
give to the other parties written notice of (i) any fact, event, condition or
circumstance that would constitute a violation or breach of this Agreement or
any Ancillary Agreement by it or of any inaccuracy in its representations and
warranties herein or in the Disclosure of any inaccuracy in its representations
and warranties herein or in the Disclosure Memorandum (or in any other
Ancillary Agreement if it were executed at Closing) or (ii) any fact, event,
condition or circumstance that will or might give rise to a claim under the Tax
Deed (if it were executed at Closing).  No disclosure by a party hereto
pursuant to the provisions of this SECTION 5.4 shall be deemed to amend or
supplement this Agreement, the Disclosure Memorandum or any other Ancillary
Agreement or to cure any misrepresentation or breach or to limit the remedies
available to the party to which such disclosure is made.

          5.5   CONFIDENTIALITY.  The Sellers shall not, and shall not permit
any of their Affiliates, employees or agents to, use any of the Confidential
Information (as defined below) or disclose any Confidential Information to any 
Person (except, for periods prior to the Closing only, in the Ordinary Course
of the Business).  As used herein, the term "CONFIDENTIAL INFORMATION" means
all trade secrets and other confidential information of or about the Company,
the Subsidiaries and/or the Business, including, without limitation, any such
information regarding the business, methods of operation, products, financial

exclusive of any such information which (a) is or becomes publicly known
through no wrongful act of any of the Sellers or their respective Affiliates,
employees or agents, (b) is rightfully received by any of the Sellers from a
third party after the Closing without similar restrictions and without breach
of its or a similar agreement, (c) is approved in advance for such use or
disclosure in writing by Teltrend or (d) is required pursuant to Law.  In the
event any of the Sellers or any of their respective Affiliates, employees or
agents becomes legally required to disclose any Confidential Information, such
Seller shall provide Teltrend with prompt notice so that Teltrend may seek a
protective order or other appropriate remedy.  Such Seller will, or will cause
its respective Affiliate, employee or agent to, cooperate with Teltrend, at the
expense of Teltrend, in seeking any such order or other remedy. Such Seller
shall not, and shall not permit its respective Affiliate, employee or agent to,
disclose any more of the Confidential Information than in the opinion of its
legal counsel it is legally required to disclose.  If any confidentiality or
nondisclosure agreements of Sellers or any of its Affiliates exist relating to
the Company, any Subsidiary or the Business, Sellers shall, at the request and
expense of Teltrend, take (or cause their Affiliates to take) all actions
reasonably requested by Teltrend to enforce such agreements or assign such
agreements to Teltrend.

          5.6   PUBLIC ANNOUNCEMENTS.  Each of Sellers, on the one hand, and
Teltrend, on the other hand, will consult with each other before issuing or
permitting the issuance of any press releases or otherwise making or permitting

this Agreement and the transactions contemplated hereby, and none of them shall
issue or permit the issuance of any such press release or make or permit the
making of any such public or trade

any Subsidiary shall have any Liability with respect to any Employee Benefit
Plan which is or in the Ordinary Course of Business has been maintained,
sponsored, offered, insured, secured or provided by, on behalf of or as part of
a general program maintained, offered, sponsored, insured, secured or provided
by any Seller or any Affiliate of any Seller other than the Company or a 
Subsidiary (a "SELLER PLAN"), except to the extent expressly provided in this 
SECTION 5.7, and all such Liabilities shall constitute Retained Liabilities 
hereunder.

          (b)   TRANSITIONAL ACCESS TO SELLER PLANS.

          (i)   PENSION SCHEME.

                (1)  the continued participation of the Company in the 
                     Securicor Scheme during the Participation Period; and

                (2)  the continued participation of the Member Employees in the
                     Securicor Scheme during the Participation Period.

          (B)   The Seller shall, so long as the payment of contributions to 
the Securicor Scheme as set forth in SECTION (b)(i)(C) is being made:-

                (1)  procure that prior to the Closing Date and during the 
                     Participation Period no action is taken or any announcement
                     made by any Person (except as required by Law) which would
                     cause the Securicor Scheme to be terminated or would alter
                     any of its provisions or result in the exercise of any 
                     discretion thereunder, in each case to the detriment of
                     Teltrend, the Company or the Member Employees, without the
                     prior written consent of Teltrend (such consent not to be
                     unreasonably delayed or withheld);

                (2)  ensure that all lump sum death in-service benefits of the
                     Member Employees under the Securicor Scheme are fully 
                     insured; and

<PAGE>   66


                (3)  use all reasonable endeavors to ensure that the Securicor 
                     Scheme remains Approved and contracted-out of the state 
                     earnings related pension scheme.

          (C)   During the Participation Period Teltrend will use all reasonable
endeavors to procure that the Company will:-
     
                (1)  while the Member Employees remain active members of the 
                     Securicor Scheme deduct from the pay of such Member
                     Employees any contributions payable by them under the
                     Securicor Scheme (including any additional voluntary
                     contributions) and promptly pay to the Securicor Scheme
                     such contributions together with employer contributions in
                     relation to such Member Employees (but the Company shall
                     not be required to pay contributions determined on a basis
                     inconsistent with the determination of those payable by
                     other employers participating in the Securicor Scheme); and

                (2)  perform in all other material respects its obligations
                     under the Securicor Scheme.

          (D)   Teltrend shall use its reasonable endeavors to procure that the
Company will give any necessary withdrawal notice at the requisite time under
the Securicor Scheme in relation to the termination of the Company's
participation in the Securicor Scheme at the end of the Participation Period.

          (ii)  OTHER SELLER PLANS. Until November 1, 1997 (other than in the 
case of the Western Provident Association health care scheme, which shall be 
until September 30, 1997), Sellers shall, and shall cause their respective
Affiliates to, permit employees of the Company or any Subsidiary to continue
to participate in those Seller Plans not identified in clause (i) above which
Teltrend may request on the same terms and conditions as such employees 
participate in such Seller Plans as of the date hereof. Teltrend shall 
reimburse each Seller and each of its respective Affiliates for its reasonable 
costs and expenses incurred in connection with the provision of such continued 
participation. Sellers shall use all reasonable commercial efforts to obtain 
prior to Closing all requisite third party Consents in respect of the foregoing.

          (iii) CONSENTS. To the extent any requisite third party Consent is not
obtained prior to Closing as contemplated by clauses (i) and (ii) above,
Teltrend shall have the right to delay the Closing until such time as it can
procure adequate (in its sole discretion) alternative arrangements to those
contemplated by this SECTION 5.7(b).

          5.8   FURTHER ASSURANCES. From and after the Closing, Teltrend, on 
the one hand, and each of the Sellers, on the other hand, shall use all         
reasonable commercial efforts to take or cause to be taken, all actions and to
do, or cause to be done, all things necessary, proper or advisable to carry out
the provisions hereof and


                                      60

to consummate and make effective the transactions contemplated hereby,
including, without limitation, the execution of further instruments of transfer
and assignment.

          5.9   COVENANT NOT TO COMPETE.  Each of the Sellers covenants with
Teltrend that it will not either on its own account or in conjunction with or
on behalf of any other Person or Persons, whether directly or indirectly, for
the period of:

          (a)   three years from the Closing Date, solicit or endeavour to
solicit in respect of any goods designed, manufactured or distributed, or any
services offered, by or on behalf of the Business the custom of any Person
which was at the Closing Date, or which during the period of 12 months prior to
the Closing had been, a customer or client of any member of the 3Net Group or
the Business in respect of such goods and/or services;

          (b)   18 months from the Closing Date, solicit or entice away, or
endeavour to solicit or entice away, from Teltrend, the Company, any Subsidiary
or the Business any Person who was at the Closing Date, or who during the
period of six months prior to the Closing Date had been, employed by any member
of the 3Net Group or the Business, whether or not such Person would commit a
breach of his or her contract of employment by reason of leaving service, save
that this clause shall not apply to any individual employed by any member of
the 3Net Group or the Business in a purely secretarial or non-managerial
administrative role; and

          (c)   three years from the Closing Date, carry on or be engaged,
concerned or interested in any business which competes with the Business (other
than as a holder of securities listed or dealt in on a recognized investment
exchange provided that such holding shall not exceed five percent of the class
of securities of which the said holding forms part).

          Each of the undertakings contained in this SECTION 5.9 is a separate
undertaking by each Seller in relation to itself and its interests and shall be
enforceable by Teltrend separately and independently of its right to enforce any
one or more of the other covenants contained in this SECTION 5.9 and in the
event that any such undertaking shall be found to be void but would be valid if
some part were deleted or the period or area of application were reduced, then
such undertaking shall apply with such modification as may be necessary to make
it valid and effective.

          5.10  NO SHOP CLAUSE.  Prior to termination of this Agreement in
accordance with ARTICLE VIII, neither Sellers nor any of their Affiliates
(including the Company), through any of their employees, officers, agents or

          5.11  ASSIGNMENT OF CERTAIN AGREEMENT.  At or prior to the Closing, 
Sellers shall cause Axiom Inc. (as successor to Securicor Telesciences Inc.)
to assign and transfer to 3Net Delaware all right, title and interest in and to
the Product Development and Technology Transfer Agreement, dated 8 December 
1994, between the Company and Securicor Telesciences Inc., on terms and
conditions satisfactory to Teltrend.

used by the Business on stationery, signage, invoices, receipts, forms, supplies
advertising and promotional materials, product, training and service 
literature and materials, computer programs or like materials existing as of

otherwise) as of the Closing Date, the Company and Subsidiaries may use such 
Marked Materials after the Closing for a period of 60 days and sell such 
Inventory (packaged or otherwise) after the Closing for a period of one year
without altering or modifying such Marked Materials or Inventory, or removing
such Securicor Trademarks. In addition, Teltrend agrees to remove the word
"Securicor" from the corporate name of the Company and each Subsidiary within
30 days following the Closing, or as soon thereafter as practicable (but in any
event within 90 days, except in the case of 3Net China), and the Company and 
each Subsidiary shall have the right to use the word "Securicor" in its         
corporate  name pending such removal. The Company and Subsidiaries shall not
use the  Securicor Trademarks after the Closing in any other manner without the
consent of Securicor.
             
          5.13  PURCHASER NAMES.  After the Closing, no Seller will, directly 
or  indirectly, use or do business, or allow any of its Affiliates to use or    
do  business, or assist any third party in using or doing business, under the
name and mark "3NET", OR "TELTREND" (or any other name or mark confusingly
similar  to either of such names and marks).

          5.14  BOOKS AND RECORDS.

          (a)   Sellers shall, and shall cause its Affiliates to, deliver to the
Company and the Subsidiaries at or prior to the Closing all Book and Records in
their possession that relate primarily to the Company, any Subsidiary or the 
Business except to the extent such items are already in the possession of the
Company or a Subsidiary.

          (b)   Teltrend will retain all Books and Records in existence on the
Closing Date and make the same reasonably available after the Closing Date for
inspection and copying by Sellers, at Sellers' expense during the normal        
business hours of the Company or Subsidiaries, as applicable, upon reasonable
request and upon reasonable notice. No such Books and Records shall be
destroyed by any of Teltrend, the Company or the Subsidiaries for a period of
seven years after the Closing without first advising Sellers in writing and
giving Sellers a reasonable

opportunity to obtain possession thereof. Without prejudice to the generality
of the foregoing, Teltrend will, and will cause the Company and each of the
Subsidiaries to, make available to Sellers and their respective
representatives all information for pre-Closing periods deemed necessary or
desirable by any Seller in preparing its respective financial statements.

          (c)   Sellers will, and will cause each of their Affiliates to,
retain all books and records and other documents pertaining to the Company, any 
Subsidiary or the Business in existence on the Closing Date not delivered to
the Company or a Subsidiary pursuant to SECTION 5.14(a) hereof and to make the
same reasonably available after the Closing Date for inspection and copying by
Teltrend, at Teltrend's expense during the normal business hours of Sellers or
such Affiliate, as applicable, upon reasonable request and upon reasonable
notice. No such books, records or documents shall be destroyed by Sellers or
any of their Affiliates for a period of seven years after the Closing without
first advising Teltrend in writing, and giving Teltrend a reasonable
opportunity to obtain possession thereof. Without prejudice to the generality
of the foregoing, Sellers will, and will cause each of their Affiliates to,
make available to Teltrend and its representatives all information deemed
necessary or desirable by Teltrend in preparing its financial statements and
the financial statements of any member of the 3Net Group.

          5.15  CERTAIN COVENANTS REGARDING REPRESENTATIONS AND WARRANTIES.

          (a)   No information of which Teltrend has knowledge (actual or
constructive) shall prejudice any claim made by Teltrend in respect of the
representations and warranties given by the Sellers pursuant to this
Agreement, any Ancillary Agreement or any other Transaction Document (the
"SELLERS' WARRANTIES") or operate to reduce any amount recoverable. No
information of which any Seller has knowledge (actual or constructive) shall
prejudice any claim made by such Seller in respect of the representations and
warranties made by Teltrend pursuant to this Agreement, any Ancillary
Agreement or any other Transaction Document (the "PURCHASER'S WARRANTIES") or
operate to reduce any amount recoverable.

          (b)   Where any statement in the Sellers' Warranties or Purchaser's
Warranties (collectively, the "WARRANTIES") is qualified by the expression "to
the best knowledge" or "is aware" or any similar expression, the party making
the statement shall be deemed to have knowledge of anything of which it would
have had knowledge had it made due and careful enquiry immediately before
giving the Warranties and of anything of which it ought reasonably to have
knowledge including, in the case of the Sellers, due and careful enquiry of
the directors, officers, employees and agents of the Company, Subsidiaries and
Business.

<PAGE>   70

          (c)   A disclosure in the Disclosure Memorandum with respect to a
particular lettered or numbered paragraph (or portion thereof) in ARTICLE 3
shall not be deemed to be an adequate disclosure or exception with respect to
any representation or warranty of any Seller contained in any other lettered
or numbered paragraph (or portion thereof) in ARTICLE 3 unless (i) such other
lettered or numbered paragraph (or portion thereof) is specifically referenced
in the disclosure, or (ii) based upon the nature of the disclosure and the
facts described therein, it would be clear to a reasonably prudent business
person that such disclosure is also related to and is an exception or
qualification with respect to such other representation or warranty.

          (d)   The Sellers shall be deemed to warrant and represent again to
Teltrend, its successors and assigns in the terms of the Sellers' Warranties
as of the Closing, and Teltrend shall be deemed to warrant and represent again
to the Sellers, their successors and assigns in terms of Purchaser's
Warranties as of the Closing, in each case with reference to the facts and
circumstances then subsisting (save that a reference to any fact, matter,
event or circumstance existing, occurring or having occurred at or before the
date of this Agreement shall also be construed as a reference to its existing,
occurring or having occurred at or before Closing).

          5.16  SET OFF. The Sellers undertake not to exercise any right of
counterclaim or set-off or any other claim or right of recovery against
Teltrend, the Company or any of the Subsidiaries, or any of their respective
officers, employees, auditors or advisers, in relation to any claim which may
be made in respect of this Agreement, any Ancillary Agreement or any other
Transaction Document.

          5.17  PREPARATION OF FINANCIAL STATEMENTS. The Sellers hereby 
acknowledge that the Financial Statements were initially prepared by Ernst & 
Young, acting as advisers to Teltrend. The Sellers acknowledge and agree that 
they had a full and fair opportunity to review the Financial Statements in
consultation with their advisers, Ernst & Young and Teltrend. The Sellers
further acknowledge and agree that the Financial Statements were initially
prepared by Ernst & Young for the sake of convenience alone and nothing
surrounding the circumstances under which the Financial Statements were
prepared shall in any way (i) limit or otherwise affect the representations,
warranties and other statements made by any Seller herein, in any Ancillary
Agreement or in any other Transaction Document regarding the Financial
Statements or (ii) limit or otherwise affect any rights which Teltrend may
have against any Seller hereunder or under any Ancillary Agreement or other
Transaction Document.

          5.18  GUARANTEES. On or as soon as practicable following Closing, 
Teltrend shall use all reasonable commercial efforts to obtain the release of 
Securicor from the sureties given by Securicor pursuant to (i) Section 8.1 of 
the U.K. Lease relating to the Ground, First and Second Floors, and (ii) 
Section 9.1 of the U.K. Lease relating to the Third Floor, and pending such 
release indemnify and hold harmless Securicor as from Closing against any 
Losses arising in respect of such sureties for any act or omission which 
occurs or is alleged to have occurred after the Closing Date.

          5.19  RESTRICTIVE TRADE PRACTICES ACT 1976. Where this Agreement is or
forms part of any agreement which is subject to registration under the RTPA,
no restriction accepted or information provision made under that agreement
shall come into effect until the day after particulars of the agreement have
been furnished to the Director General of Fair Trading under Section 24 RTPA. If
any party shall wish to furnish such particulars, the other parties will
render such co-operation and undertake such action as may reasonably be
required of them for such purpose so that particulars may be furnished as soon
as practicable following the signature of this Agreement and each of the
parties consents to the disclosure of all information so furnished. In this
SECTION 5.19 the words and terms "agreement" and "subject to registration"
shall have the meanings respectively given to them by the RTPA and the
reference to "restrictions accepted" or "information provisions made" under
the agreement shall be to restrictions accepted or information provisions made
by virtue of which the agreement is subject to registration.

          5.20  COMMERCIAL FILINGS. At the request of Teltrend, the Sellers 
shall use their best efforts to update, or cause to be updated, the filings with

Subsidiaries into compliance in all material respects with applicable Law
prior to the Closing.

          5.21  ELIMINATION OF CERTAIN ENCUMBRANCES. At or prior to the Closing,
Sellers shall cause those Encumbrances identified on SCHEDULE 5.21 to the

shall cause evidence thereof to be recorded with the appropriate registry) and
such Encumbrances shall not be considered "Permitted Encumbrances" for
purposes of any representation, warranty or agreement made pursuant to any
Transaction Document as of or after the Closing; provided, however, that the
fact that the Encumbrance identified at Item 3 of SCHEDULE 5.21 to the
Disclosure Memorandum is not so fully discharged at or prior to Closing shall
not constitute a failure to satisfy Teltrend's condition to Closing set forth
in SECTION 6.2 hereof so long as it is the result of circumstances reasonably
beyond the control of any of the Sellers and Sellers agree at Closing to
indemnify Teltrend to its satisfaction against any Loss or other Liability
related to such Encumbrance.

          5.22  BAKER TILLY FINANCIAL STATEMENTS. At or prior to Closing,

audit of the Baker Tilly Financial Statements. Teltrend shall deliver, or shall
cause to be delivered, to Sellers and Baker Tilly drafts of the financial
information to be contained in the Baker Tilly Financial Statements for
consideration and audit by Baker Tilly no later than five Business Days prior
to Closing. The costs and expenses of Teltrend and/or its representatives
incurred in connection with the preparation of the financial information for
inclusion in the Baker Tilly Financial Statements as contemplated by this
SECTION 5.22, and the costs and expenses of Baker Tilly incurred in connection
with the audit of the Baker Tilly Financial Statements, shall be borne and paid
50% by Teltrend and 50% by the Sellers. From and after the Closing, Sellers
shall, and shall use their best efforts to cause Baker Tilly to, assist and
cooperate with Teltrend in the

filing made by Teltrend pursuant to the U.S. securities laws.

          5.23  TAX ELECTIONS FOR PURPOSES OF U.S. CODE SECTION 338. The parties
acknowledge that Teltrend may, in its sole discretion, make one or more
elections under Section 338 of the U.S. Code with respect to the purchase of
the Shares contemplated hereby. Sellers hereby agree to (i) cooperate, and to
cause their Affiliates to cooperate, with Teltrend in respect of any such
election which Teltrend determines it is necessary or advisable to make and
(ii) not take, and not permit any of their Affiliates to take, any action
inconsistent with, or which would jeopardize the benefits to Teltrend
contemplated by, any such election.

Company pursuant to the U.K. Leases, and shall use all reasonable commercial

due and owing to such lessor as of a date no earlier than five Business Days
prior to Closing and, if so determined, shall pay all such amounts, in full and
final settlement of any disputes which may be existing between the Company and
such lessor.

          5.25  CERTAIN ACTIONS WITH RESPECT TO NDL. Prior to the Closing,
Sellers shall cause all amounts payable to the former shareholders of NDL       
on October 1, 1997 under that certain Memorandum of Agreement, dated March
1996, among the Company, the minority shareholders named therein, Richard Bruce
Ash, Aslan Solutions Limited and NDL, to be paid in full, which shall be funded
through a cash contribution by 3Net Holdings to the capital of the Company in
an amount equal to such amounts payable.

          5.26  REGULATORY FILINGS. As soon as practicable following the date
of this Agreement, the parties shall make or cause to be made such filings
as Teltrend determines may be required under the Anticompetition Acts with
respect to the consummation of the transactions contemplated hereby, and shall
thereafter file or cause to be filed any supplementary information as may be
requested pursuant to the Anticompetition Acts by the Governmental Authority
charged with administration and/or enforcement thereof.  Each of the parties
shall use all reasonable commercial efforts to obtain any Consent Teltrend
determines is required under the Anticompetiton Acts (provided no party shall
be required to dispose of any assets, lines of business or equity interests in
order to obtain such Consents) with respect to the consummation of the
transactions contemplated hereby.

          5.27  3NET AUSTRALIA LEASE ARRANGEMENTS. Prior to Closing, the Sellers

Miller Street, North Sydney, New South Wales, Australia; and (ii) Part Level
20, Waterfront Place, I Eagle Street, Brisbane, Queensland, Australia;
provided, however, that the fact that any Liability under either of such Leases
is not so fully paid and discharged prior to Closing shall not constitute a
failure to satisfy Teltrend's condition to Closing

set forth in SECTION 6.2 hereof so long as it is the result of circumstances 
reasonably beyond the control of any Seller.

material respects as of the Closing as if made as of the Closing (it being

failure of such representations and warranties to be true and accurate in all

representations and warranties as deemed to be given as of the Closing pursuant
to SECTION 5.15 hereof are to be true and accurate in all respects for purposes
of each other covenant, agreement or provision contained herein or in any other

Company, any Subsidiary or the Business after Closing. Any Consent determined 
by Teltrend to be required under any Anticompetition Act shall have been duly 
obtained.

failure of such representations and warranties to be true and accurate in all
material respects shall constitute a failure to satisfy Sellers' condition to
Closing set forth in this Section 7.1, such representations and warranties as

          (b)   by Teltrend, if the conditions set forth in ARTICLE VI hereof

the transactions contemplated hereby are not consummated as provided above,
each and every representation, warranty and covenant contained in this
Agreement, any Ancillary Agreement or any other Transaction Document shall
expire and none of the parties hereto shall be under any liability whatsoever
with respect to any such representation, warranty or covenant; provided
however, that notwithstanding the foregoing, (i) the agreements contained in
SECTIONS 5.5, 5.6, 5.16 and ARTICLE X (and those provisions of ARTICLE I or
other definitions necessary for interpretation thereof) shall survive
termination of this Agreement, and (ii) subject to SECTION 10.10 hereof, each
party shall be and remain liable to the others in the event that the failure
so to close hereunder shall occur as a consequence of the failure of such
party to perform fully its covenants and agreements hereunder or the material
breach by such party of its representations or warranties contained in this
Agreement, any Ancillary Agreement or any other Transaction Document (except 
that no party shall be liable to any other party under this SECTION 8.2 for 
loss of profits or any other consequential damage of any kind or if Teltrend 
terminates the Agreement because the Consent described in Item 4 of SCHEDULE 
1.6 to the Disclosure Memorandum is not received on or prior to such 
termination).

any Losses imposed on, sustained, incurred or suffered by or asserted against 
any Purchaser Indemnified Party, directly or indirectly, with respect to, in
connection with, arising from or alleged to result from or arise out of or in
connection with:

          (i)   a breach by any of the Sellers of any representation or warranty
made by any of the Sellers in this Agreement, any Ancillary Agreement or any 
other Transaction Document;

          (ii)  a breach by any of the Sellers or the Company of any covenant or

such amounts (subject to SECTION 9.1(c) below) shall be payable.

          (c)   Except as set forth in SECTION 9.1(d) hereof, no Purchaser
Indemnified Party shall make any claim under SECTION 9.1(a) above unless the
individual claim exceeds $15,000, save that for the purposes of satisfying
this de minimis limit each Purchaser Indemnified Party shall be entitled to
aggregate a series of similar individual claims arising out of the same set of
facts and circumstances.

          (d)   The provisions of Sections 9.1(b) and 9.1(c) hereof shall not 
apply to any Losses arising from or relating to, or alleged to arise from or 
relate to, any of the Retained Liabilities, and no such Losses shall be counted
against the dollar limitations contained in SECTION 9.1(b) hereof.

          (e)   None of the Sellers shall be liable in respect of a claim made
pursuant to SECTION 9.1(a) hereof to the extent that it arises or is increased
as a result only of (i) any change in generally accepted accounting practice
after the Closing Date, or (ii) any change in the date to which the Company or
any of the Subsidiaries make up their accounts.

          9.2   INDEMNIFICATION OF SELLER.

          (a)   Teltrend shall indemnify, defend and hold harmless each of the
Sellers and their respective officers, directors, employees, agents,
representatives and shareholders, and their respective heirs, executors,
personal representatives, successors and assigns (the "SELLER INDEMNIFIED
PARTIES") from and against any and all Losses imposed on, sustained, incurred
or suffered by or asserted against any Seller Indemnified Party with respect
to, in connection with, arising from or alleged to result from or arise out of
or in connection with:

          (i)   a breach by Teltrend of any representation or warranty made by 
          Teltrend contained in this Agreement, any Ancillary Agreement or any 
          other Transaction Document; and


                                      71
                                      


<PAGE>   78


          (ii)  a breach by Teltrend of any covenant or agreement made by
          Teltrend contained in this Agreement, any Ancillary Agreement or any
          other Transaction Document.

          (b)   The aggregate liability of Teltrend in respect of SECTION 9.2(a)
above shall not exceed $1,000,000. No liability shall attach to Teltrend in
respect of Losses pursuant to SECTION 9.2(a) above unless the aggregate amount
of the liability of Teltrend in respect of all such Losses shall exceed
$100,000, in which event this limitation shall cease to apply and the whole of
such amounts (subject to SECTION 9.2(c) below) shall be payable.

          (c)   No Seller Indemnified Party shall make any claim under SECTION 
9.2(a) above unless the individual claim exceeds $15,000, save that for the 
purposes of satisfying this de minimis limit each Seller Indemnified Party 
shall be entitled to aggregate a series of similar individual claims arising 
out of the same set of facts and circumstances.

          9.3   FOREIGN CURRENCY ADJUSTMENTS. Payments under this ARTICLE IX 
shall be made in dollars. In the event that any indemnification payment 
required to be made under this ARTICLE IX shall be denominated in a currency 
other than dollars, the amount of such payment shall be translated into dollars
using the foreign exchange rate for such currency as reported by The Financial 
Times determined in accordance with the following rules:

          (a)   with respect to any Indemnifiable Losses arising from the
                payment by a financial institution under a guarantee, comfort
                letter, letter of credit, foreign exchange contract or similar
                instrument, the foreign exchange rate for such currency shall be
                determined as of the date on which such financial institution
                shall have been reimbursed; and

          (b)   with respect to any other Indemnifiable Losses, the foreign
                exchange rate for such currency shall be determined as of the
                date that notice of the claim with respect to such Indemnifiable
                Losses shall be given to the Indemnitee.

          9.4   PROCEDURES FOR INDEMNIFICATION.

          (a)   NOTICE OF THIRD PARTY CLAIMS. If a claim or demand is made
against  a Person entitled to indemnification under SECTION 9.1 or 9.2 hereof
(an "INDEMNITEE") by any third party (a "THIRD PARTY CLAIM") as to which such
Indemnitee is entitled to indemnification pursuant to this Agreement, such
Indemnitee shall notify the party with such indemnification obligation (the
"INDEMNIFYING PARTY") in writing, and in reasonable detail, of the Third Party
Claim promptly (and in any event within 30 Business Days) after receipt by such
Indemnitee of written notice of the Third Party Claim; provided, however, that
failure to give such notification shall not affect the Indemnitee's right to
indemnification hereunder except to the extent the Indemnifying Party shall
have been actually prejudiced as a result of such failure. Thereafter, the
Indemnitee shall deliver to the Indemnifying Party, promptly (and in any event
within 30 Business Days) after the Indemnitee's receipt thereof, copies of all
notices and documents (including court papers) received by the Indemnitee
relating to the Third Party Claim.

          (b)   LEGAL DEFENSE OF THIRD PARTY CLAIMS. If a Third Party Claim is
made against an Indemnitee, the Indemnifying Party shall be entitled to
participate with the Indemnitee in the defence thereof at its own expense and
assisted by counsel of its own choosing (such counsel being subject to the
consent of the Indemnitee, which consent shall not be unreasonably withheld or
delayed), subject to the Indemnitee's right to settle, compromise and discharge
the Third Party Claim as provided in SECTION 9.4(c) hereof.

          (c)   SETTLEMENT OF THIRD PARTY CLAIMS. In no event shall an 
Indemnitee settle, compromise or discharge a Third Party Claim without 
providing prior written notice to the Indemnifying Party, which shall have the
option within 15 Business Days following receipt of such notice to:

          (i)   approve and agree to pay the settlement;

          (ii)  approve and agree to pay the amount of the settlement,
          reserving the right to contest the Indemnitee's right to indemnity; or
          
          (iii) disapprove the settlement and assume in writing all past and
          future responsibility for the Losses related to such Third Party
          Claim (including all of Indemnitee's prior expenditures in
          connection therewith).


                                      73
                                      
<PAGE>   80

          (d)   OTHER CLAIMS. Any claim on account of an Indemnifiable Loss 
which does not result from a Third Party Claim shall be asserted by written 
notice given by the Indemnitee to the applicable Indemnifying Party.  Such 
Indemnifying Party shall have a period of 15 Business Days after the receipt 
of such notice within which to respond thereto. If such Indemnifying Party 
does not respond within such 15 Business-Day period, such Indemnifying Party 
shall be deemed to have refused to accept responsibility to make payment. If 
such Indemnifying Party does not respond within such 15 Business-Day period or 
rejects such claim in whole or in part, such Indemnitee shall be free to 
pursue such remedies as may be available to such party under applicable Law or 
under this Agreement.

          9.5   INDEMNIFICATION PAYMENTS. Indemnification required by this
ARTICLE IX shall be made by periodic payments of the amount thereof during the
course of the investigation or defense, as and when bills are received or Loss
is incurred. If any Indemnifying Party makes any payment to an Indemnitee
pursuant to SECTION 9.1 or 9.2 hereof with respect to an Indemnifiable Loss and
such Indemnitee subsequently recovers from a third party any amount (whether by
way of payment, discount, credit, set-off or otherwise) in respect of that
Indemnifiable Loss, such Indemnitee shall, once it has received such amount,
immediately repay or procure the repayment to the Indemnifying Party so much of
the amount paid by such Indemnifying Party as does not exceed the sum recovered
from the third party less all reasonable costs, charges and expenses paid,
incurred or accrued by such Indemnitee or its Affiliates (as the case may be)
in recovering that sum from the third party and less any Taxation paid,
incurred or accrued by such Indemnitee or its Affiliates on the money recovered
from the third party. Nothing in this SECTION 9.5 shall be deemed to require
any Indemnitee to make any claim for insurance or other third party recovery in
respect of any Loss which is or may be subject to indemnification under this
ARTICLE IX.
         
          9.6   OBLIGATIONS ABSOLUTE. The foregoing contractual obligations of
indemnification set forth in this ARTICLE IX shall:

          (i)  also apply to any and all Third Party Claims that allege that any
               Indemnitee is independently, directly, vicariously or jointly 
               and severally liable to such third party;

          (ii) to the extent permitted by applicable Law, apply even if the
               Indemnitee is partially negligent or otherwise partially
               culpable or at fault, whether or not such Liability arises under 
               any doctrine of strict liability; and

          (iii) be in addition to any Liability that an Indemnifying
                Party may have other than pursuant to this Agreement.


                                      
                                      74
<PAGE>   81

          9.7   REMEDIES CUMULATIVE. The remedies provided in this ARTICLE IX
shall be cumulative and shall be in addition and without prejudice to any other
rights or the seeking of any and all other remedies by an Indemnitee against
any Indemnifying Party.

          9.8   EXCHANGE OF INFORMATION. In connection with the handling of
current or future actions or Third Party Claims, the parties may determine that
it is in their mutual interest to exchange privileged or confidential
information. If so, the parties agree to discuss whether it is in their mutual
interest to enter into a joint defense agreement or information exchange
agreement to maintain the confidentiality of their communications and to permit
them to maintain the confidentiality of proprietary information or information
that is otherwise confidential or subject to any applicable privilege,
including but not limited to the attorney-client, work product, executive,
deliberative process or self-evaluation privileges.

          9.9   CONTRIBUTION. To the extent that any indemnification provided 
for hereunder is unavailable to an Indemnitee or is insufficient in respect of
any the Indemnifiable Losses of such Indemnitee then the Indemnifying Party, in
lieu of indemnifying such Indemnitee hereunder, shall contribute to the amount
paid or payable by such Indemnitee as a result of such Indemnifiable Losses (i)
in such proportion as is appropriate to reflect the relative benefits received
by the Indemnifying Party on the one hand and the Indemnitee on the other hand
from the transaction or other matter which resulted in the Indemnifiable Losses
or (ii) if the allocation provided by clause (i) above is not permitted by
applicable Law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault
of the Indemnifying Party on the one hand and of the Indemnitee on the other
hand in connection with the action, inaction, statements or omissions that
resulted in such Indemnifiable Losses as well as any other relevant equitable
considerations.

          9.10  SURVIVAL.  All covenants and agreements of any party hereto set
forth herein or in any Ancillary Agreement or other Transaction Document shall
survive and continue in full force and effect after the Closing.  Further, all
representations and warranties contained in this Agreement, any Ancillary
Agreement or any other Transaction Document shall survive the Closing and shall
remain in effect for a period of two years after the Closing Date
(after which time no claims shall be made pursuant to this ARTICLE IX in
respect thereof);  provided, however, that  (i) any representations or
warranties relating to Taxation or matters under any Environmental Law or with
respect to any Environmental Claim shall not expire until the running of their
respective statutes of limitation, (ii) any representation or warranty which is
not true when made and which is made fraudulently or with intent to defraud or
mislead shall survive for a period six years after the Closing Date, and (iii)
the representations and warranties contained in SECTIONS 3.7, 3.8 and 3.9
hereof shall survive indefinitely.  Each of the Sellers agrees that,
notwithstanding any right of any of Teltrend to fully investigate the affairs of
each of the Company and Subsidiaries and notwithstanding any knowledge of facts
determined or determinable by Teltrend pursuant to such investigation or right
of investigation, Teltrend has the right to rely fully upon the
representations, warranties, indemnities, covenants and agreements of each of
the Sellers and the Company (as applicable) contained in this Agreement, any
Ancillary Agreement or any other Transaction Document, all of which are
material and none of which supersedes any obligation of any of the Sellers or
the Company (as applicable) under any of such representations, warranties,
indemnities, covenants or agreements.  Nothing contained herein shall in any
way be deemed to limit or otherwise compromise by reference to the passage of
time, a time limitation or a specified date the ability of any Purchaser
Indemnified Party to obtain indemnification from any Seller pursuant to this
ARTICLE IX with respect to any Retained Liability or breach of any covenant or
agreement of any Seller and/or the Company contained herein or in any other
Transaction Document.

          9.11  RELATIONSHIP TO TAX DEED.  The indemnification provided in this
ARTICLE IX shall be in addition to, and shall in no way limit or compromise,
any indemnification provided under the terms of the Tax Deed, and vice versa.


                                  ARTICLE X

                                MISCELLANEOUS

          10.1  WRITTEN AGREEMENT TO GOVERN.  This Agreement and the Ancillary

dicussions among them.

          10.2  SEVERABILITY. In the event any one or more of the provisions

enforceability of the remaining provisions contained herein and therein shall
not in any way be affected or impaired thereby.  The parties shall endeavour in

       as occurring in a Pre-Closing Period and (ii) depreciation, amortization
       and depletion for any Straddle Period shall be apportioned on a daily

       Taxation purposes, Taxation items for any Straddle Period shall be 
       apportioned between the Pre-Closing Period and the Post-Closing Period

     achieve the method of apportionment described in the preceding sentence.

     jointly and severally agree with and undertake to the Purchaser and as a

               to be or have been received for taxation purposes; or

          (c)  the supply of any service or business facility of any kind
               (including a loan of money or the letting, hiring, licensing or

               received for taxation purposes; or

          (d)  any Event which gives rise to a Liability to
               Taxation on deemed (as opposed to actual) Profits; or

          (e)  any Event which results in a Group Company becoming liable
               to pay or bear a Liability to Taxation directly or primarily
               chargeable against or

               which is not expressed to be exclusive of any Value Added Tax
               payable in respect of the supply in circumstances where the
               supply was stated or agreed, under the terms of the contract or
               on the invoice receipt or other document relating to the supply,
               to be exempt or zero-rated for Value Added Tax purposes but
               which is subsequently determined or found to have been a
               standard-rated supply; or

          (i)  the failure by a Group Company to pay all income tax and
               National insurance premiums (both employer's and employees') due
               under the system commonly known in the United Kingdom as the

     Group Company to indemnify, defend and hold harmless each Group Company
     and the Purchaser, and keep indemnified each Group Company and the
     Purchaser, against any depletion in or reduction in value of its or their
     assets or increase in its or their liabilities as a result of any
     inheritance tax which:


          (a)  at the Closing Date is a charge on any of the shares or
               assets of any Group Company or gives rise to a power to sell,
               mortgage or charge any of the shares or assets of the Group
               Company; or

          (b)  after the Closing Date becomes a charge on or gives rise

               additional inheritance tax payable on the death of any person

               existed at the Closing Date or would, if the death had occurred
               immediately before the Closing Date and the inheritance tax

     determined in accordance with sub-clauses 4.2 to 4.6 provided that
     where any Relevant Amount is paid to any person under this Deed in
     respect of any Claim for Taxation any other Relevant Amount which may also
     be due under this Deed to such person in respect of the same Claim for
     Taxation shall be reduced by the amount of such payment. There shall, in
     addition to any Relevant Amount calculated in accordance with this clause,
     be paid to the Purchaser such further amounts as may be due under
     sub-clause 3.6, clause 6, and clause 8 and sub-clause 10.6.

4.2  Where a Group Company is placed under a liability to make a payment of
     or in respect of Taxation, the Relevant Amount shall be the amount of
     such payment.

4.3  Where a Group Company suffers the loss in whole or in part, of any
     Relief, or a Relief is deducted from or in computing or is set off
     against Profits or Taxation:

          (a)  if the Relief is deducted from or set off against
               Taxation, the Relevant Amount shall be the amount of the Relief
               so deducted or set off;

          (b)  if the Relief is deducted from or in computing or is set
               off against Profits, the Relevant Amount shall be the amount of
               Taxation saved as a consequence of such deduction or set off;
               and


          (c)  if the Group Company loses the Relief, the Relevant Amount
               shall be the amount of Taxation which would have been saved had
               such Relief been available on the assumption that Profits or
               Taxation in respect of the earliest period for which such Relief
               is available are such that the Relief could have been fully
               utilized and that such Relief would have been utilized by set
               off against or by deduction from or in computing any such
               Profits or Taxation. For this purpose any amount of Taxation
               actually payable as a result of the loss, denial or deprivation
               of Relief referred to in this paragraph (c) shall be disregarded.


                                     -17-

<PAGE>   108


4.4  Where as a result of or in consequence of a Claim for Taxation a
     Group Company has a right to the repayment of any Taxation nullified,
     canceled or reduced or has any such right to set off against any
     Liability to Taxation arising as a result of or in consequence of any
     Claim for Taxation for which a claim may be made, the Relevant Amount
     shall be the amount of the repayment which would otherwise have been
     obtained or the amount by which such repayment is reduced, as the case
     may be.

4.5  Where a Group Company is placed under a liability to make a
     repayment as described in clause 3.4, the Relevant Amount shall be the
     amount of such repayment.

4.6  In any other case the Relevant Amount shall be the amount of the
     depletion in or reduction in value of the assets or increase in the
     liabilities of the Purchaser or the relevant Group Company as reasonably
     determined by the Purchaser.


5.   POWER TO SELL: INHERITANCE TAX


     In determining for the purposes of sub-clause 3.3 whether a charge on or
     power to sell, mortgage or charge any of the shares or assets of any
     Group Company exists at any time the fact that any Taxation is not yet
     payable or may be paid by instalments shall be disregarded and such
     Taxation shall be treated as becoming due and a charge or power to sell,
     mortgage or charge as arising on the date of the transfer of value or
     other date or event on or in respect of which it becomes payable or
     arises and the provisions of Section 213 of the Inheritance Tax Act 1984
     shall not apply thereto.

6.   WITHHOLDINGS AND DEDUCTIONS

6.1  All sums payable by the Sellers under this Deed shall be paid free and
     clear of all deductions or withholdings whatsoever save only as may be
     required by Law. If any such deductions or withholdings are required by
     Law the Sellers shall be obliged to pay such sum as will after such
     deduction or withholding has been made leave the amount the recipient
     would have been entitled to receive in the absence of any such
     requirement to make a deduction or withholding.


                                     -18-

<PAGE>   109

6.2  In the event that a Tax Authority seeks to charge to tax any sum
     paid to the Purchaser or any Group Company hereunder as a result of the
     indemnities or other obligations contained in this Deed or in the
     Agreement the Sellers shall be obligated to pay such sum as will after
     payment of the tax so charged leave a sum equal to the amount that would
     otherwise be payable under any such indemnity or obligation.

7.   REFUNDS OF TAXATION; AMENDED RETURNS; CARRYOVERS.

7.1  Subject to Section 7.3 hereof, if Purchaser or any Group Company
     receives a Taxation refund with respect to Taxation arising in a
     Pre-Closing Period, Purchaser shall pay, within the ninety (90) days
     following the receipt of such Taxation refund, the amount of such Taxation
     refund to the Sellers. If Sellers receive a Taxation refund with respect
     to Taxation arising in any Post-Closing Tax Period, within ninety (90)
     days following the receipt of such Taxation refund, Sellers will pay the
     amount of such Taxation refund to Purchaser.

7.2  Amended Tax Returns.

          (a)  Subject to Section 7.3 hereof, any amended Tax Return or
     claim for Taxation refund for any Pre-Closing Period other than a Straddle
     Period shall be filed, or caused to be filed, only by Sellers. Sellers
     shall not, without the prior written consent of Purchaser (which consent
     shall not be unreasonably withheld or delayed), make or cause to be made
     any such filing, to the extent such filing, if accepted, reasonably might
     change the Liability to Taxation of Purchaser or any Group Company for any
     Tax Period.

          (b) An amended Tax Return or claim for Taxation refund for
     any Straddle Period shall be filed by the Party responsible for filing the
     original Tax Return hereunder if either Purchaser or Seller so requests,
     except that such filing shall not be done without the consent (which shall
     not be unreasonably withheld or delayed) of Purchaser (if the request is
     made by Sellers) or of Sellers (if the request is made by Purchaser).


                                     -19-

<PAGE>   110

          (c) Any amended Tax Return or claim for Taxation refund for any
     Post-Closing Period other than a Straddle Period shall be filed, or caused
     to be filed, only by Purchaser, who shall not be obligated to make (or
     cause to be made) such filing. Purchaser shall not, without the prior
     written consent of Sellers (which consent shall not be unreasonably
     withheld or delayed) file, or cause to be filed, any amended Tax Return or
     claim for Taxation refund for any Post-Closing Period to the extent that
     such filing, if accepted, reasonably might change the Liability to
     Taxation of any Seller for any Pre-Closing Period.

7.3  If any Taxation loss or credit with respect to the Group Companies
     arising a Post-Closing Period may be carried back and included in any Tax
     Return filed or caused to be filed by any Seller or any Affiliate of any
     Seller (other than a Group Company) with respect to any of the Group
     Companies for any Pre-Closing Period, Purchaser may elect (at its expense)
     to carry back such Taxation items (subject to Sellers' consent, which
     consent shall not be unreasonably withheld or delayed), in which case
     Sellers shall pay to Purchaser amount equal to the Tax Benefit resulting
     from such carryback of Taxation loss or credit, provided that Sellers
     shall not be required to file any carryback claim unless Purchaser so
     requests in writing and agrees to pay the reasonable expenses related to
     the claim for refund.

8.   CONDUCT OF CLAIMS

8.1  Within thirty (30) Business Days of the Purchaser or any of the
     Group Companies becoming aware of a Claim for Taxation relevant for the
     purposes of this Deed, the Purchaser or such Group Company (as the case
     may be), shall give written notice of the Claim for Taxation to the
     Sellers; provided, however, that failure to give such notification shall
     not affect the Purchaser's or any Group Company's right to indemnification
     hereunder except to the extent the Sellers have actually been prejudiced 
     as a result of such failure. If the Sellers shall indemnify and secure the
     relevant Group Company or Group Companies to their reasonable satisfaction
     against all losses, costs, damages and expenses (including, without 
     limitation, interest on overdue Taxation), which may be incurred by the 
     relevant Group Company or Group Companies, then the Purchaser and the 
     relevant

                                      
                                     -20-
                                      

<PAGE>   111


     Group Company or Group Companies shall take such action and give such
     information and assistance in connection with the affairs of the relevant
     Group Company or Group Companies as the Sellers may reasonably and
     promptly by written notice request to avoid, resist, appeal or compromise
     the Claim for Taxation.

8.2  No Group Company shall be obliged to appeal against any Taxation
     Assessment raised on it if, having given the Sellers written notice of
     the receipt of that Taxation Assessment in accordance with sub-clause
     8.1, it has not within twenty (20) Business Days of the giving of such
     notice received instructions in writing from the Sellers, in accordance
     with sub-clause 8.1, to make that appeal.

8.3  The Sellers shall not be entitled to request the Purchaser or a Group
     Company to take any action under this clause if in respect of any Claim
     for Taxation notified under sub-clause 8.1 it appears to the Purchaser
     (and would appear to a reasonably prudent business person) that either
     the Sellers or the relevant Group Company, whilst it was under the
     control of the Sellers, has committed acts or omissions which may
     constitute fraud or misfeasance.

8.4  For the avoidance of doubt, the actions which the Sellers may reasonably
     request under sub-clauses 8.1 and 8.2 shall include the relevant Group
     Company or Group Companies applying to postpone (so far as legally
     possible) the payment of any Taxation but the Sellers shall not be
     entitled under sub-clauses 8.1 and 8.2 to request that it be allowed to
     take on or take over the conduct of all or any proceedings arising in
     connection with the Claim for Taxation in question. The Purchaser and the
     relevant Group Company or Group Companies shall provide the Sellers with
     copies of all correspondence entered into and notes of any conversations
     or meetings with any Tax Authority to the extent that such correspondence
     or notes relate to the Claim for Taxation in question. The Sellers shall
     keep all such information confidential.


                                     -21-

<PAGE>   112


8.5  The relevant Group Company or the Purchaser (as the case may be) shall
     be at liberty without reference to the Sellers to admit, compromise,
     settle, discharge or otherwise deal with any Claim for Taxation after
     whichever is the earliest of:

     (a)  the service of a notice in writing on the relevant Group
          Company or the Purchaser by any of the Sellers to the effect that it
          considers the Claim for Taxation should no longer be resisted;

     (b)  the expiry of a period of ten (10) Business Days following
          the service of a notice by the relevant Group Company or the
          Purchaser (as the case may be) on the Sellers requiring the Sellers
          to clarify or explain the terms of any request made under sub-clause
          8.1; and

     (c)  if appropriate, the expiration of any period prescribed by
          applicable legislation for the making of any appeal against either
          the Claim for Taxation in question or the decision of any court or
          tribunal in respect of any such Claim for Taxation, as the case may
          be.

8.6  The Sellers shall be bound to accept for the purposes of this Deed any
     admission, compromise, settlement or discharge of any Claim for Taxation
     (and the outcome of any proceedings relating thereto) made or arrived at
     in accordance with the provisions of this clause 8.

9.   PREPARATION AND FILING OF TAX RETURNS.


9.1  Sellers' Responsibilities. Sellers shall have the right and obligation to 
     timely prepare and file, or cause to be timely prepared and filed, when 
     due:

     (a)  any Tax Return that is required to include the operations,
          ownership, assets or activities of the Group Companies for Tax
          Periods ending on or before the Closing Date; and

     (b)  all Tax Returns for any transfer Taxes or other related
          transfer costs to be paid by Sellers pursuant to the term hereof or
          the Agreement.


                                     -22-

<PAGE>   113


9.2  Purchaser's Rights and Responsibilities.

     (a)  Purchaser shall have the right and obligation to timely prepare
          and file, or cause to be timely prepared and filed, when due, all Tax
          Returns that are required to include the operations, ownership,
          assets or activities of the Group Companies for any Tax Periods
          ending after the Closing Date (including all Straddle Period Tax
          Returns).

9.3  Preparation of Tax Returns.

     (a)  Sellers shall prepare or cause to be prepared and provide
          to Purchaser such Taxation information as is reasonably requested by
          Purchaser with respect to the operations, ownership, assets or
          activities of the Group Companies for Pre-Closing Periods.

     (b)  Each of the Sellers shall, on the one hand, and Purchaser
          shall, on the other, with respect to any Tax Return which such party
          is responsible hereunder for preparing and filing, or causing to be
          prepared and filed, make such Tax Return and related work papers
          available for review by the other parties if the Tax Return (A) is
          with respect to Taxation for which any of the other parties or one
          of its Affiliates may be liable hereunder or under Applicable Tax
          Law, or (B) claims Taxation Benefits which any of the other parties
          or one of its Affiliates is entitled to receive hereunder. The
          filing party shall use its reasonable best efforts to make Tax
          Returns available for review as required under this paragraph
          sufficiently in advance of the due date for filing such Tax Returns
          to provide the non-filing party or parties with a meaningful
          opportunity to analyze and comment on such Tax Returns and have such
          Tax Returns modified before filing, and such non-filing party shall
          accept the position of the filing party unless such position is
          contrary to the provisions of Section 9.4 hereof.

9.4. Consistency of Accounting Method.  Any Tax Return which includes or is 
     based on the operations, ownership, assets or activities of any Group 
     Company for any Pre-Closing


                                     -23-

<PAGE>   114

     Period, and any Tax Return which includes or is based on the
     operations, ownership, assets or activities of any Group Company for any
     Post-Closing Period to the extent the items reported on such Tax Return
     might reasonably increase any Taxation liability of any Seller for any
     Pre-Closing Period or any Straddle Period shall be prepared in accordance
     with past Taxation accounting practices used with respect to the Tax
     Returns in question (unless such past practices are no longer permissible
     under the Applicable Tax Law), and to the extent any items are not covered
     by past practices (or in the event such past practices are no longer
     permissible under the Applicable Tax Law), in accordance with reasonable
     Taxation accounting practices selected by the filing party with respect to
     such Tax Return under this Deed with the consent (not to be unreasonably
     withheld or delayed) of the non-filing party or parties.

10.  PROTECTION OF PURCHASER AND THE GROUP COMPANIES

     Notwithstanding anything to the contrary in clause 8, neither the
     Purchaser nor any Group Company shall be obliged to take any action, the
     effect of which is, or is reasonably likely, to increase the amount of
     Taxation payable by the Group Companies or the Purchaser in respect of
     accounting periods ending after the Closing Date beyond what that
     liability would have been but for the taking of that action, and shall not
     be obliged to take any action the effect of which is reasonably
     foreseeable to be likely to prejudice the ability of the Group Companies
     to order their affairs in such a way as to minimize their liability to
     Taxation in respect of any such later accounting periods.

11.  DUE DATE FOR PAYMENT

11.1 Where a Liability to Taxation to which this Deed applies involves the
     Purchaser or the relevant Group Company being placed under a liability to
     make a payment or increased payment of Taxation (including, without
     limitation, any case where a payment under this Deed itself results in
     further Taxation becoming due), the Sellers shall pay to the Purchaser (or
     the relevant Group Company) in cleared funds the amount claimed in
     respect of that Liability to Taxation under this Deed or any further
     amount which the


                                     -24-
                                      
<PAGE>   115

     Sellers are liable to pay by virtue of clause 6 on or before the date
     which is the later of the date five (5) Business Days after demand is made
     by the Purchaser and the second Business Day prior to the date on which
     the Taxation in question is payable to the Tax Authority demanding the
     same.

11.2 Where a Claim for Taxation to which this Deed applies involves the
     reduction, nullification or cancellation of a right to a repayment of
     Taxation, the Sellers shall pay to the Purchaser (or the relevant Group
     Company) the amount claimed under this Deed in respect of that Claim for
     Taxation on or before the date which is the later of the date five (5)
     Business Days after demand is made by the Purchaser and, in the case of a
     reduced repayment, the date such reduced repayment is received, or in the
     case of a nullified or canceled repayment the date when such repayment
     would have been due were it not for its nullification or cancellation
     (which latter date for the purposes of this Deed shall, where no due date
     for repayment is specified by any applicable legislation, be deemed to be
     the date fifteen (15) Business Days after the date on which the relevant
     claim for repayment has been made or, if no such claim was required, the
     date fifteen Business Days after the date on which all the relevant facts
     giving rise to the repayment were provided or available to the Tax
     Authority concerned).

11.3 Where a Claim for Taxation to which this Deed applies involves the loss,
     deduction or set off of any Relief, the Sellers shall pay to the
     Purchaser (or the relevant Group Company) the amount claimed under this
     Deed in respect of that Claim for Taxation on or before the date
     whichever is the later of the date five (5) Business Days after demand is
     made by the Purchaser or the Group Company concerned, as the case may be,
     and:

          (a)  in a case where such Relief is deducted from or in computing
               or is set off against Profits or Taxation, the date when the
               Taxation saved as a result would otherwise have been payable to
               the Taxation Authority demanding the same; and


                                     -25-

<PAGE>   116


          (b)  in a case where a Group Company loses (in whole or in
               part) such Relief, the date when the Taxation (for which the
               Group Company would be liable as a result of such loss) would be
               payable to the Tax Authority demanding the same on the
               assumption that such Taxation would be payable in respect of the
               earliest period for which the relevant Relief would have been
               available. For this purpose, any actual Claim for Taxation which
               results from the loss of the Relief shall be disregarded.

11.4 Where an amount is claimed under this Deed by virtue of the provisions
     of sub-clause 3.4, the Sellers shall pay to the Purchaser the amount
     claimed under the said sub-clause on or before the date whichever is the
     later of five (5) Business Days after demand is made by the Purchaser and
     the fifth Business Day prior to the date on which an amount is repaid to
     the person demanding the same in the circumstances described in
     sub-clause 3.4.

11.5 Where an amount is claimed under sub-clause 3.6 the Sellers shall pay
     to the Purchaser or the relevant Group Company the amount claimed on or
     before the date which is five (5) Business Days after demand is made for
     the same.

11.6 Any sums not paid by the Sellers on the date specified in
     sub-clauses 11.1 to 11.5 for payment of the same (the "Due Date") shall
     bear interest (which shall accrue from day to day after as well as before
     any judgment for the same) from the Due Date at the rate per annum of the
     base rate of National Westminster Bank plc applicable from time to time
     (or in, the absence of such rate at such similar rate as the Purchaser
     shall select) plus four percent to and including the day of actual payment
     of such sums, such interest to be compounded quarterly. Such interest
     shall be paid on the demand of the Purchaser or the relevant Group Company
     concerned.

12.1 Any notice to be given under this Deed shall be given in accordance with
     the notice provisions of Section 10.3 of the Agreement.

12.2 This Deed shall be governed by English law and the parties submit to the
     exclusive jurisdiction of the English Courts.

13.  SPECIAL PROVISIONS REGARDING GROUP RELIEF

     If requested to do so by Securicor, the Company, subject to the
     restrictions imposed by Sections 402 to 413 inclusive ICTA, agrees to
     consent to the surrender of losses, in respect of the financial year to
     30th September 1997, to Securicor or any Affiliate of Securicor and in
     consideration for giving such consent the Company shall be paid an amount
     equal to 33% of the amount of losses surrendered, such payment to be made
     on 1st July 1998. In the event that the amount of losses which Securicor is
     requesting the Company to surrender is not determined by 1st July 1998
     then payment when made (such payment to be made in any event by 30
     September 1999 or the date the losses are determined, whichever is the
     earlier), will be subject to an interest charge from 1 July 1998 to the
     actual date of payment at the annual rate of LIBOR (as defined in the
     Agreement) plus 100 basis points compounded annually.
