which are held in the name of BEI or any of its Subsidiaries (other than any
Subsidiary of Technologies), or any of their respective employees, officers,
directors, stockholders, agents, or otherwise, on behalf of Technologies (or its
Subsidiaries) shall be duly and validly transferred by BEI to Technologies (or
its Subsidiaries).

          (f) LEASE AMENDMENTS.  At or prior to the Effective Time, or as soon
as reasonably practicable thereafter, amendments shall be executed to each of
the leases to which BEI is a party and which provide for the lease of real or

Technologies for BEI as lessee or lessor, as the case may be, and excuse BEI
from any future liabilities or responsibilities with respect thereto.

          (g) TRANSFER OF AGREEMENTS.

              (i) BEI hereby agrees that at or prior to the Effective Time or as
soon as reasonably practicable thereafter, subject to the limitations set forth
in this Section 2.1(g) and the terms of the Ancillary Agreements, it will, and
it will cause its Subsidiaries (other than Technologies or any of its
Subsidiaries) to, assign, transfer and convey to Technologies all of BEI's or
such Subsidiaries' respective right, title and interest in and to any and all
agreements that, in BEI's sole judgment, relate exclusively to the Technologies
Business.

             (ii) Subject to the provisions of this Section 2.1(g) and the terms
of the Ancillary Agreements, any agreement to which either or both of the
parties hereto or any of their Subsidiaries is a party that inures, in BEI's
sole judgment, to the benefit of both the BEI Business and the Technologies
Business shall be assigned in part, on or prior to the Effective Time or as soon
as reasonably practicable thereafter, so that each party shall be entitled to
the rights and benefits inuring to its business under such agreement.

            (iii) The assignee of any agreement assigned, in whole or in part,
hereunder (an "Assignee"), shall assume and agree to pay, perform, and fully
discharge all obligations of BEI under such agreement or, in the case of a
partial assignment under paragraph (g) (ii), Technologies's related portion of
such obligations as determined in accordance with the terms of the relevant
agreement, where determinable on the face thereof, and otherwise as determined
in accordance with the practice of the parties prior to the Distribution.

            (iv)  Notwithstanding anything in this Agreement to the contrary,
this Agreement shall not constitute an agreement to assign any agreement, in
whole or in part, or any rights thereunder if the agreement to assign or attempt
to assign, without the consent of a third party, would constitute a breach
thereof or in any way adversely affect the rights of the Assignee thereof. Until
such consent is obtained, or if an attempted assignment thereof would be
ineffective or would adversely affect the rights of any party hereto so that the
Assignee would not, in fact, receive all such rights, the parties will cooperate
with each other in any arrangement designed to provide for the Assignee the
benefits of, and to permit the Assignee to assume liabilities under, any such
agreement.

with respect to the payment and administration of accounts payable and the
administration of accounts receivable, the purchase of capital assets and
equipment and the management of inventories.

                                       7

     2.4  CAPITAL STRUCTURE.  Each of BEI and Technologies agrees to use
commercially reasonable efforts to achieve both an allocation of consolidated
indebtedness of BEI and a capital structure of Technologies which substantially
reflects the capital structure after the Distribution of Technologies set forth
in the Information Statement under the heading "Capitalization."

     2.5  ASSUMPTION AND SATISFACTION OF LIABILITIES.  Except as otherwise
specifically set forth in any Ancillary Agreement, from and after the Effective
Time, (i) BEI shall, and shall cause its Subsidiaries to, assume, pay, perform
and discharge all BEI Liabilities, and (ii) Technologies shall, and shall cause
its Subsidiaries to, assume, pay, perform and discharge all Technologies
Liabilities.

     2.6  RESIGNATIONS.  BEI shall cause all its directors, officers and
employees, other than those continuing in their present roles, as described in
the Information Statement, to resign, effective as of the Effective Date, from
all positions as directors, officers and employees of BEI or as officers or
directors of BEI Medical or its subsidiaries.

     2.7  FURTHER ASSURANCES.  In case at any time after the Effective Time any
further action is reasonably necessary or desirable to carry out the purposes of
this Agreement and the Ancillary Agreements, the proper officers of each party
to this Agreement shall take all such necessary action.  Without limiting the
foregoing, BEI and Technologies shall use commercially reasonable efforts to
obtain all consents and approvals, to enter into all amendatory agreements and
to make all filings and applications that may be required for the consummation
of the transactions contemplated by this Agreement and the Ancillary Agreements,
including, without limitation, all applicable governmental and regulatory
filings and novations.

     2.8  NO REPRESENTATIONS OR WARRANTIES.  Each of the parties hereto
understands and agrees that, except as otherwise expressly provided, no party
hereto is, in this Agreement or in any other agreement or document contemplated
by this Agreement or otherwise, making any representation or warranty
whatsoever, including, without limitation, as to title, value or legal
sufficiency.  It is also agreed and understood that all assets either
transferred to or retained by the parties, as the case may be, shall be "as is,
where is" and that (subject to Section 2.7) the party to which such assets are
to be transferred hereunder shall bear the economic and legal risk that any
conveyances of such assets shall prove to be insufficient or that such party's
or any of the Subsidiaries' title to any such assets shall be other than good
and marketable and free from encumbrances.  Similarly, each party hereto
understands and agrees that no party hereto is, in this Agreement or in any
other agreement or document contemplated by this Agreement or otherwise,
representing or warranting in any way that the obtaining of any consents or
approvals, the execution and delivery of any amendatory agreements and the
making of any filings or applications contemplated by this Agreement will
satisfy the provisions of any or all applicable agreements or the requirements
of any or all applicable laws or judgments, it being agreed and understood that
the party to which any assets are transferred shall bear the economic and legal
risk that any necessary consents or approvals are not obtained or that any
requirements of laws or judgments are not complied with.

     2.9  ELIMINATION OF GUARANTEES.  Except as otherwise specified in any
Ancillary Agreement, BEI and Technologies shall use commercially reasonable
efforts to have, on or prior

                                       8
<PAGE>
 
to the Effective Time, or as soon as reasonably practicable thereafter, BEI and
any of its Subsidiaries removed as guarantor of or obligor for any Technologies
Liability or Liabilities.  To the extent that BEI or any of its Subsidiaries
cannot be removed as guarantor of or obligor for any such Technologies Liability
or Liabilities, Technologies agrees that until such Technologies Liability or
Liabilities shall have been discharged in full, Technologies will take no
action, and will not permit any of its Subsidiaries to take any action, which
will have the effect of increasing the contingent liability or exposure of BEI
or any of its Subsidiaries with respect to such Technologies Liability or
Liabilities.

     2.10 WITNESS SERVICES.  At all times from and after the Effective Time,
each of BEI and Technologies shall use commercially reasonable efforts to make
available to each other, upon reasonable written request, its and its
Subsidiaries' officers, directors, employees and agents as witnesses to the
extent that (i) such persons may reasonably be required in connection with the
prosecution or defense of any Action in which the requesting party may from time
to time be involved and (ii) there is no conflict in the Action between the
requesting party and itself.  A party providing witness services to the other
party under this Section shall be entitled to receive from the recipient of such
services, upon the presentation of invoices therefor, payments for such amounts
relating to supplies, disbursements and other out-of-pocket expenses and direct
and indirect costs of employees who are witnesses as may be reasonably incurred
in providing such witness services.

     2.11 CERTAIN POSTDISTRIBUTION TRANSACTIONS.  Each of BEI and Technologies
agrees that (i) it shall comply with and otherwise not take action inconsistent
with each representation and statement made, or to be made, to Davis, Polk &
Wardwell in connection with such firm's rendering an opinion to BEI and
Technologies as to certain tax aspects of the Distribution and (ii) until two
years after the Distribution Date, it will maintain its status as a company
engaged in the active conduct of a trade or business, as defined in Section
355(b) of the Code.

     2.12 TRANSFERS NOT EFFECTED PRIOR TO EFFECTIVE TIME; TRANSFERS DEEMED
EFFECTIVE AS OF EFFECTIVE TIME.  To the extent that any transfers contemplated
by this Article II shall not have been consummated at or prior to the Effective
Time, the parties shall cooperate to effect such transfers as promptly following
the Effective Time as shall be practicable.  Nothing herein shall be deemed to
require the transfer of any assets or the assumption of any Liabilities which by
their terms or operation of law cannot be transferred; provided, however, that
the parties hereto and their respective Subsidiaries shall cooperate to seek to
obtain any necessary consents or approvals for the transfer of all assets and
Liabilities contemplated to be transferred pursuant to this Article II.  In the
event that any such transfer of assets or Liabilities has not been consummated,
from and after the Effective Time, the party retaining such asset or Liability
shall hold such asset in trust for the use and benefit of the party entitled
thereto (at the expense of the party entitled thereto) or retain such Liability
for the account of the party by whom such Liability is to be assumed pursuant
hereto, as the case may be, and take such other action as may be reasonably
requested by the party to whom such asset is to be transferred, or by whom such
Liability is to be assumed, as the case may be, in order to place such party,
insofar as is reasonably possible, in the same position as would have existed
had such asset or Liability been transferred as contemplated hereby.  As and
when any such asset or Liability becomes transferable, such transfer shall be
effected forthwith.  The parties agree that, as of the Effective

                                       9
<PAGE>
 
Time, each party hereto shall be deemed to have acquired complete and sole
beneficial ownership over all of the assets, together with all rights, powers
and privileges incident thereto, and shall be deemed to have assumed in
accordance with the terms of this Agreement all of the Liabilities, and all
duties, obligations and responsibilities incident thereto, which such party is
entitled to acquire or required to assume pursuant to the terms of this
Agreement.

     2.13 ANCILLARY AGREEMENTS.  At or prior to the Effective Time, each of BEI
and Technologies shall enter into, and/or (where applicable) shall cause their
respective Subsidiaries to enter into, the Ancillary Agreements and any other
agreements in respect of the Distribution reasonably necessary or appropriate in
connection with the transactions contemplated hereby and thereby.

                                   ARTICLE 3

                             ACCESS TO INFORMATION

     3.1  PROVISION OF CORPORATE RECORDS.  After the Effective Time, upon the
prior written request by one party for specific and identified agreements,
documents, books, records or files including, without limitation, computer
files, microfiche, tape recordings and photographs (collectively, "Records"),
relating to or affecting the requesting party, the other party shall arrange, as
soon as reasonably practicable following the receipt of such request, for the
provision of appropriate copies of such Records (or the originals thereof if the
party making the request has a reasonable need for such originals) in the
possession of such other party or any of its Subsidiaries, but only to the
extent such items are not already in the possession of the requesting party.

     3.2  ACCESS TO INFORMATION.

          (a) From and after the Effective Time, BEI and Technologies shall
afford to the other and its authorized accountants, counsel and other designated
representatives (including governmental representatives and auditors in
connection with governmental claims or audits) reasonable access during normal
business hours, subject to appropriate restrictions for classified, privileged
or confidential information, to the personnel, properties, books and records of
such party and its Subsidiaries insofar as such access is reasonably required by
the other party.

          (b) For a period of five years following the Effective Time, each of
BEI and Technologies shall provide to the other, promptly following such time at
which such documents shall be filed with the Securities and Exchange Commission
(the "Commission"), all documents that shall be filed by it and by any of its
respective Subsidiaries with the Commission pursuant to the periodic and interim
reporting requirements of the Securities Exchange Act of 1934, and the rules and
regulations of the Commission promulgated thereunder.

     3.3  REIMBURSEMENT; OTHER MATTERS.

          (a) Except to the extent otherwise contemplated by any Ancillary
Agreement, a party providing Records or access to information to the other party
under this Article III shall

                                       10
<PAGE>
 
be entitled to receive from the recipient, upon the presentation of invoices
therefor, payments for such amounts relating to supplies, disbursements and
other out-of-pocket expenses as are reasonably incurred in providing such
Records or access to information.

          (b) The parties hereto shall comply with those document retention
policies set forth in Schedule 3.3(b) hereto or established and agreed to in
writing by their respective authorized officers on or prior to the Effective
Time in respect of Records and related matters.

     3.4  CONFIDENTIALITY.  Each of BEI and its Subsidiaries and Technologies
and its Subsidiaries shall not use or permit the use of (without the prior
written consent of the other) and shall hold, and shall cause its consultants
and advisors to hold, in strict confidence, all information concerning the other
parties in its possession, its custody or under its control (except to the
extent that (A) such information has been in the public domain or becomes part
of the public domain through no fault of such party, (B) such information has
been later lawfully acquired by such party, without an obligation of confidence,
from a third party who is legally free to disclose such information, (C) this
Agreement or any other Ancillary Agreement or any other agreement entered into
pursuant hereto permits such use or disclosure of such information or (D) such
information is independently developed by such party without reference to such
information) to the extent such information (x) relates to the period up to the
Effective Time, (y) relates to any Ancillary Agreement or (z) is obtained in the
course of performing services for the other party pursuant to any Ancillary
Agreement, and each party shall not (without the prior written consent of the
other) otherwise release or disclose such information to any other person,
except such party's auditors and attorneys, unless compelled to disclose such
information by judicial or administrative process or unless such disclosure is
required by law and such party has used commercially reasonable efforts to
consult with the other affected party or parties prior to such disclosure.  To
the extent that a party hereto is compelled by judicial or administrative
process to disclose such information under circumstances in which any
evidentiary privilege would be available, such party agrees to assert such
privilege in good faith prior to making such disclosure.  Each of the parties
hereto agrees to consult with each relevant other party in connection with any
such judicial or administrative process, including, without limitation, in
determining whether any privilege is available, and further agrees to allow each
such relevant party and its counsel to participate in any hearing or other
proceeding (including, without limitation, any appeal of an initial order to
disclose) in respect of such disclosure and assertion of privilege.

                                   ARTICLE 4

                               DISPUTE RESOLUTION

     In the event of a controversy, dispute or claim arising out of, in
connection with, or in relation to the interpretation, performance,
nonperformance, validity or breach of this Agreement or any of the Ancillary
Agreements or otherwise arising out of, or in any way related to this Agreement
or any of the Ancillary Agreements, including, without limitation, any claim
based on contract, tort, statute or constitution (collectively, "Agreement
Disputes"), the Presidents (or their designees) of the respective parties shall
negotiate in good faith for a reasonable period of time to settle such Agreement
Dispute.

                                       11
<PAGE>
 
     If after such reasonable period such Presidents (or their designees) are
unable to settle such Agreement Dispute (and in any event after 60 days have
elapsed from the time the parties began such negotiations), such Agreement
Dispute shall be determined, at the request of either party, by arbitration
before a single arbitrator conducted in San Francisco, California, before and in
accordance with the then-existing Rules of Practice and Procedure of the San
Francisco office of JAMS/Endispute, Inc. ("JAMS") (the "Rules"), and any
judgment or award rendered by the arbitrator shall be final, binding and
nonappealable (except upon grounds specified in 9 U.S.C. section 10 or
California Code of Civil Procedure section 1285 et seq. as in effect on the date
hereof), and judgment may be entered by any state or Federal court having
jurisdiction thereof in accordance with Section 7.19 hereof.  Each party shall
have the right to conduct the following discovery: one-time service of up to 25
document requests upon the other party, with receipt of all responsive documents
within 30 days; exchange of witness lists identifying any witnesses the party
intends to call at the arbitration hearing and any other persons with material
information about the dispute, including a brief description of each identified
person's knowledge; the taking of depositions of any fact (non-expert)
witnesses, however, the total time for all of each party's depositions of fact
witnesses shall not exceed ten eight-hour days, including breaks; and the
designation of up to three expert witnesses per party, with the right to depose
the opposing party's experts, however the total time for all of each party's
depositions of expert witnesses shall not exceed two eight-hour days, including
breaks.  Any controversy concerning whether an Agreement Dispute is an
arbitrable Agreement Dispute, whether arbitration has been waived, whether an
assignee of this Agreement is bound to arbitrate, or as to the interpretation of
enforceability of this Article 4 shall be determined by the arbitrator.  The
arbitrator shall be a retired or former judge of any Federal or California trial
or appellate court or such other qualified person as the parties may agree to
designate, provided such individual has had substantial professional experience
with regard to settling commercial disputes.  The arbitration hearing shall
commence no later than six months following the service of the Demand for
Arbitration.  The arbitrator shall make detailed findings of fact and law in
writing in support of his or her decision and shall serve his or her award and
findings of fact within 15 days following the later of the conclusion of the
arbitration hearing or submission of the final briefs.  The arbitrator shall be
entitled, if appropriate, to award any remedy in such proceedings, including,
without limitation, monetary damages, specific performance and all other forms
of legal and equitable relief; provided, however, the arbitrator shall not be
entitled to award punitive damages and shall not reform, modify or materially
change this Agreement or any of the Ancillary Agreements.  In his or her award
the arbitrator shall allocate, in his or her discretion, among the parties to
the arbitration all costs of the arbitration, including, without limitation, the
fees and expenses of the arbitrator and reasonable attorneys' fees, costs and
expert witness expenses of the parties.  The parties hereto agree to comply with
any award made in any such arbitration proceedings that has become final in
accordance with the Rules and agree to the entry of a judgment in any
jurisdiction upon any award rendered in such proceedings becoming final under
the Rules.

                                   ARTICLE 5

                                   INSURANCE

     5.1  COVERAGE.  As of the Effective Time, coverage of Technologies and its
Subsidiaries shall cease under current Company Policies, except as provided in
this Article 5.  From and after the Effective Time, Technologies and its
Subsidiaries will be responsible for obtaining and maintaining insurance
coverages for their own account, and, with respect to policies of commercial
general liability insurance, shall name BEI as an additional insured with
respect to liabilities assumed by BEI under the Indemnity Agreement.  To the
extent that liabilities arising from the activities of Technologies prior to the
Effective Time are covered by Company Policies, and result in the assertion of
claims against BEI after the Effective Time, it is the intention of the parties
that, without increasing or expanding the risks assumed by the insurer,
Technologies will have the benefit of such insurance coverage after the
Effective Time.  No assignment pursuant to Section 5.2 is intended to increase
the liability of any insurer under a Company Policy.  If and when such
assignment occurs, it is BEI's intention to assign only such coverage as would
have been available to BEI in respect of the Technologies Business if the
Distribution had not occurred.

     5.2  CLAIMS FOLLOWING THE EFFECTIVE TIME; WAIVER.

          (a) If, subsequent to the Effective Time, any person shall assert a
claim or institute a suit, action or proceeding against Technologies or any of
its Subsidiaries (including, without limitation, where Technologies or its
Subsidiaries are joint defendants with other persons) with respect to any
injury, loss, liability, damage or expense incurred or claimed to have been
incurred prior to the Effective Time in the course of or in connection with the
conduct of the Technologies Business and which injury, loss, liability, damage
or expense may constitute an insured or insurable occurrence under one or more
Company Policies, BEI shall, at the time such claim is asserted, be deemed,
without need of further documentation, to assign to Technologies or any of its
Subsidiaries an interest in the relevant Company Policies (unless such
assignment would render BEI's coverage for such occurrence thereunder void),
subject to any limitations or obligations of Technologies contemplated by this
Article 5, if necessary, and then only to the extent necessary, to convey to
Technologies or any of its Subsidiaries rights of indemnity and the right to be
defended by or at the expense of the insurer, with respect to any such claim,
suit, action, proceeding, injury, loss, liability, damage or expense provided,
however, that, with respect to Company Policies for which Technologies has
payment obligations pursuant to Section 5.5 or otherwise, Technologies and its
Subsidiaries shall only have the rights set forth under this Section 5.2(a) with
respect to such Company Policies if such payment obligations have been satisfied
by Technologies.

          (b) Notwithstanding any contrary provision contained herein, BEI shall
at all times retain the Company Policies, together with the rights, benefits and
privileges thereunder, including without limitation the right to invade or
exhaust any Company Policy by submission of claims, settlement or otherwise;
provided, that the retention of the Company Policies by BEI is not intended to
limit, inhibit or preclude any right granted pursuant to Section 5.2(a), and

                                       13
<PAGE>
 
provided further that Section 5.2(a) is not intended to limit, inhibit or
preclude any rights, benefits or privileges BEI may have under Company Policies.

     5.3  ADMINISTRATION.  From the Effective Time until one full policy year
after the end of the policy year in which the Effective Time occurs (the
"Insurance Transition Period"), Technologies shall be responsible for Claims
Administration with respect to BEI Liabilities and Technologies Liabilities.
BEI hereby appoints Technologies as its agent and attorney in fact to assert
claims against insurance carriers and to otherwise perform Claims Administration
with respect to BEI Liabilities during the Insurance Transition Period.
Technologies shall be responsible for Claims Administration with respect to
Technologies Liabilities with respect to which BEI is engaged in coverage
litigation as of the Effective Time.

     5.4  INSURANCE PROCEEDS.  Proceeds received with respect to claims made
under Company Policies shall be paid to BEI with respect to BEI Liabilities and
to Technologies with respect to Technologies Liabilities.

     5.5  RETROSPECTIVELY RATED POLICIES.  From and after the Effective Time,
any additional premiums payable or rebates of premiums previously paid in
respect of any retrospectively rated Company Policy shall be paid or collected
by BEI.  BEI shall be reimbursed by Technologies, or shall distribute to
Technologies, amounts equal to the portion of any such additional premium or
rebate, as applicable, which relates to the Technologies Business.  BEI shall
notify Technologies when it becomes aware of a proposed adjustment.

     5.6  AGREEMENT FOR WAIVER OF CONFLICT AND SHARED DEFENSE.  In the event
that Insured Claims of more than one of the parties hereto exist relating to the
same occurrence, the parties shall jointly defend and waive any conflict of
interest necessary to the conduct of the joint defense.  Nothing in this Section
5.6 shall be construed to limit or otherwise alter in any way the obligations of
the parties to this Agreement, including those created by this Agreement, by
operation of law or otherwise.

     5.7  COOPERATION.  The parties hereto agree to use commercially reasonable
efforts to cooperate with respect to the various insurance matters contemplated
by this Agreement.

     5.8  INDEMNITY AGREEMENT.  The parties hereto agree that the amount which
any indemnifying party is or may be required to pay to an indemnified party
pursuant to the Indemnity Agreement shall be reduced (including, without
limitation, retroactively) by any proceeds of insurance policies or other
amounts actually recovered by or on behalf of such indemnified party in
reduction of the related Liability (as defined in the Indemnity Agreement).  If
an indemnified party shall have received the payment (an "Indemnity Payment")
required by the Indemnity Agreement from an indemnifying party in respect of any
Liability (as defined in the Indemnity Agreement) and shall subsequently
actually receive proceeds of insurance policies or other amounts in respect of
such Liability, then such indemnified party shall repay to such indemnifying
party a sum equal to the amount actually received (up to but not in excess of
the amount of any Indemnity Payment made thereunder).  An insurer who would
otherwise be obligated to pay any claim shall not, solely by virtue of the
indemnification provisions contained in the Indemnity Agreement, be relieved of
its responsibility with respect thereto, or have any

                                       14
<PAGE>
 
subrogation rights with respect thereto, it being expressly understood and
agreed that no insurer or any other third party shall be entitled to a benefit
they would not otherwise be entitled to receive in the absence of the
indemnification provisions contained in the Indemnity Agreement by virtue
thereof.

                                   ARTICLE 6

                     EMPLOYEE OBLIGATIONS AND BENEFIT PLANS

     6.1  BEI RETIREMENT PLAN.  From the Effective Time, and through December
31, 1997, Technologies employees will continue to participate in the BEI
Retirement Plan.  Effective January 1, 1998, Technologies will establish a
qualified retirement plan with a salary deferral (401(k)) feature ("Technologies
401(k) Plan") for its and its Subsidiaries' employees.  Prior service with BEI
or any of its Subsidiaries shall be recognized under the Technologies 401(k)
Plan for the purpose of meeting all vesting, eligibility and other service-
related requirements thereunder.  Effective January 1, 1998, Technologies' and
its Subsidiaries' employees will no longer participate in the BEI Retirement
Plan but will become participants in the Technologies 401(k) Plan in accordance
with the terms of the Technologies 401(k) Plan.  Effective as of, or as soon as
administratively feasible following, January 1, 1998, the account balances of
the Technologies and its Subsidiaries' employees held in the BEI Retirement Plan
will be transferred to the Technologies 401(k) Plan in a trustee-to-trustee
transfer (the "Transferred Assets").  Technologies hereby agrees to assume, and
shall indemnify and hold harmless BEI from and against, any and all claims
brought against BEI or any of its Subsidiaries under the Technologies 401(k)
Plan or with respect to the Transferred Assets.

     6.2  SUPPLEMENTAL PLAN.  Effective as of the Effective Time, Technologies
shall adopt a plan substantially similar to the BEI Supplemental Plan (the
"Technologies Supplemental Plan").  Prior service with BEI or any of its
Subsidiaries shall be recognized under the Technologies Supplemental Plan for
the purpose of meeting all vesting, eligibility and other service-related
requirements thereunder.  As of, or as soon as administratively feasible
following, the Effective Time, assets, benefits and liabilities accrued under
the BEI Supplemental Plan, with respect to participants in the BEI Supplemental
Plan who become employees of Technologies or who become or remain employees of
any Subsidiary of Technologies, shall be transferred to, and thereafter
administered under, the terms of the Technologies Supplemental Plan.
Technologies hereby agrees to assume, and shall indemnify and hold harmless BEI
from and against, any and all claims brought against BEI or any of its
Subsidiaries under the Technologies Supplemental Plan or with respect to the
assets, benefits or liabilities transferred from the BEI Supplemental Plan to
the Technologies Supplemental Plan.

     6.3  STOCK OPTIONS AND RESTRICTED STOCK.

          (a) STOCK OPTIONS.  BEI and Technologies shall cause vested and
unvested incentive stock options and nonstatutory stock options to purchase BEI
Common Stock outstanding at the Effective Time to be converted to vested and
unvested incentive stock options and nonstatutory stock options, as appropriate,
to purchase Technologies Common Stock issued

                                       15
<PAGE>
 
under the Technologies Equity Plan.  The conversion will be accomplished
according to the following rules:

              (i) the excess of the aggregate fair market value of the shares of
Technologies Common Stock subject to the option after the conversion over the
aggregate option price of such shares shall be essentially equal to, and in any
event no more than, the excess of the aggregate fair market value of the shares
of BEI Common Stock subject to the option before such conversion over the
aggregate option price of such shares;

             (ii) on a share by share comparison, the ratio of the option price
to the fair market value of the shares of Technologies Common Stock subject to
the option immediately after the conversion may not be more favorable to the
optionee than the ratio of the option price to the fair market value of the
shares of BEI Common Stock subject to the option immediately before the
conversion; and

            (iii) the new option does not give the option holder additional
benefits that such holder did not have under the old option.

     For purposes of the calculation identified above, the fair market value of
Technologies Common Stock after the conversion shall be calculated in accordance
with accepted practices for such determinations, as determined by the management
of Technologies in consultation with its professional advisers.

          (b) RESTRICTED STOCK.  BEI and Technologies shall cause each holder as
of the Distribution Record Date of shares of BEI Common Stock issued pursuant to
the BEI Restricted Stock Plan ("BEI Restricted Stock") to receive as a result of
the Distribution vested and unvested shares of Technologies Common Stock equal
to the number of vested and unvested shares of BEI Restricted Stock held by such
holder on the Distribution Record Date.  Vesting of the unvested shares of
Technologies Common Stock so issued shall be in accordance with the vesting
requirements of the BEI Restricted Stock Plan; provided, however, that
employment by Technologies or Electronics or any of either company's respective
Subsidiaries shall be deemed to be employment by BEI or any of its Subsidiaries
for purposes of satisfying the vesting requirements of the BEI Restricted Stock
Plan.  For the purpose of vesting unvested shares of BEI Restricted Stock under
the vesting requirements of the BEI Restricted Stock Plan, employment by
Technologies or any of its Subsidiaries shall be deemed to be employment by BEI
or any of its Subsidiaries.

     6.4  OTHER BENEFITS.  From the Effective Time, and through December 31,
1997, Technologies employees and employees of its Subsidiaries will continue to
participate in the health, disability and other welfare benefit plans (other
than plans described in Section 6.5) sponsored by BEI.  Effective January 1,
1998, Technologies will adopt welfare benefit plans and programs (the
"Technologies Benefit Plans") affording benefits similar to those provided under
BEI's welfare benefit plans.  Effective January 1, 1998, Technologies employees
and employees of its Subsidiaries will no longer participate in the BEI welfare
benefit plans and programs but will become participants in the Technologies
Benefit Plans in accordance with the terms of the Technologies Benefit Plans.
BEI will not be responsible for and will incur no liability with

                                       16
<PAGE>
 
respect to the Technologies Benefit Plans.  The BEI group medical plan or plans
shall provide required group health continuation coverage under the Consolidated
Omnibus Budget Reconciliation Act of 1984 ("COBRA") for qualifying events that
occur prior to January 1, 1998.  Technologies, with respect to its and its
Subsidiaries' employees, shall provide COBRA coverage for qualifying events that
occur on or after January 1, 1998.  Technologies hereby agrees to assume, and
shall indemnify and hold harmless BEI from and against, all claims brought
against BEI or any of its Subsidiaries under the Technologies Benefit Plans,
including, without limitation, any claims under COBRA for qualifying events of
Technologies' and its Subsidiaries' employees and dependents that occur on or

                           DOCUMENT RETENTION POLICY


I.   GENERAL GUIDELINES AFFECTING DOCUMENT RETENTION

     Generally, the document retention policy is shaped by the following
requirements and issues:

     A.   LEGAL REQUIREMENTS.  The comprehensive document retention policy must
conform to legal requirements that affect the businesses.

     B.   INDUSTRY PRACTICE.  Standards and customs in the industries in which
the companies do business will often determine record retention policies.  These
standards and customs, coupled with accrued experience within the companies,
often provide a basis for decisions made concerning the relative utility of
competing policies.

     C.   INDIVIDUAL REQUIREMENTS.  Need for access and retrieval of documents
also determines the parameters of the document retention policy.

II.  PARTICULAR CATEGORIES OF DOCUMENTS AND THEIR RETENTION

     Several categories of documents that bear special consideration are
identified below.  While minimum retention periods are suggested, the retention
of the documents identified below and of documents not included in the
identified categories should be determined primarily by the application of the
general guidelines affecting document retention identified above, as well as any
other pertinent factors known to the respective company.

     A.   TAX RECORDS.  Tax records include, but may not be limited to,
documents concerning payroll, expenses, proof of deductions, business costs,
accounting procedures, and other documents concerning the Companies revenues.
Tax records should be retained for at least six years from the date of filing
the applicable return.

     B.   EMPLOYMENT RECORDS/PERSONNEL RECORDS.  State and federal statutes
require the companies to keep certain recruitment, employment and personnel
information.  The companies should also keep personnel files that reflect
performance reviews and any complaints brought against the Company or individual
employees under applicable state and federal statutes.  The companies should
also keep all final memoranda and correspondence reflecting performance reviews
and actions taken by or against personnel in the employee's personnel file.
Employment Records/Personnel Records should be retained for six years.

     C.   BOARD MATERIALS.  Meeting minutes should be retained in perpetuity in
the companies' respective minute books.  A clean copy of all Board materials
should be kept for no less than three years by each company.

                                       1.
<PAGE>
 
     D.   PRESS RELEASES/PUBLIC FILINGS.  The companies should retain permanent
copies of all press releases and publicly filed documents under the theory that
each company should have its own copy to test the accuracy of any document a
member of the public can theoretically produce against that company.

          With regard to Registration Statement materials or any periodic
reports filed with the SEC or any government agency, a copy of the materials
actually filed or publicly disseminated should be kept in a permanent file by
the company.

     E.   LEGAL FILES.  Counsel should be consulted to determine the retention
period of particular documents.

     F.   MARKETING AND SALES DOCUMENTS.  Each company should keep final copies
of marketing and sales documents for the same period of time it keeps other
corporate files --generally three years.

          An exception to the three year policy may be sales invoices,
contracts, leases, licenses and other legal documentation.  These documents
should be kept for at least three (3) years beyond the life of the agreement.

     G.   DEVELOPMENT/INTELLECTUAL PROPERTY AND TRADE SECRETS.  Development
documents are often subject to intellectual property protection in their final
form (e.g., patents and copyrights).  The documents detailing the development
process are often also of value to a company and are protected as a trade secret
where the company:

          (a)  derives independent economic value from the secrecy of the
               information; and

          (b)  the company has taken affirmative steps to keep the information
               confidential.

          Each company should keep all documents designated as containing trade
secret information for at least the life of the trade secret.

     H.   CONTRACTS.  Final, execution copies of all contracts entered into by a
company should be kept by that company.  Each company should retain copies of
the final contracts for at least three (3) years beyond the life of the
agreement, and longer in the case of publicly filed contracts.

     I.   ELECTRONIC MAIL.  Email that needs to be saved should be either:

          (a)  printed in hard copy and kept in the appropriate file; or

          (b)  downloaded to a computer file and kept electronically or on disk
               as a separate file.

                                       2.
<PAGE>
 
          The retention period depends upon the subject matter of the email, as
covered elsewhere in this policy.

pursuant to this Agreement.

     4.2  LIMITS ON DISCLOSURE.  The receiving Party shall treat such
Confidential Information in the same manner and with the same degree of care as
it uses with respect to its own Confidential Information of like nature and

consultants are bound to respect all confidentiality obligations provided for in
this Agreement.

not apply with respect to any Confidential Information that:

          4.3.1  PUBLIC KNOWLEDGE.  Is generally available to the public or

receiving Party of confidentiality obligations under this Agreement or prior
agreements between the Parties concerning the Confidential Information; or

          4.3.2  RECEIVED FROM THIRD PARTY.  Is received without a
confidentiality obligation from a third party who is legally free to disclose
such Confidential Information and who did not receive such Confidential
Information in confidence from the disclosing Party; or

the disclosing Party or its Subsidiaries; or

          4.3.4  SUCCESSOR IN INTEREST.  Is disclosed to any permitted assignee

the provisions of this Agreement; or

          4.3.5  INDEPENDENTLY DEVELOPED.  Is independently developed by the
receiving Party without reference to the Confidential Information received from
the disclosing Party or its Subsidiaries.

     4.4  PERMITTED DISCLOSURES.  The provisions of Sections 4.1 and 4.2
notwithstanding, in exercising the rights granted under this Agreement, any
Party may disclose Confidential Information to others for purpose of
sublicensing, provided that any sublicenses pursuant to which any Confidential
Information is disclosed shall have first entered into a written confidentiality
and non-use obligation at least as stringent as that imposed on the Parties
pursuant to this Agreement.

     4.5  SUBPOENA OR DEMAND.  The provisions of Sections 4.1 and 4.2
notwithstanding, a Party may disclose Confidential Information if compelled to
do so pursuant to a subpoena or

<PAGE>
 
similar demand for production of documents in connection with any suit or
arbitration proceeding, any administrative procedure or before a governmental or

disclosure any available evidentiary privilege, and (c) the receiving Party
shall use its best efforts to maintain the confidential nature of the
Confidential Information by protective order or other means.

Section 5.1, the rights and obligations set forth in Sections 2, 3, 4, and 9
shall survive.

     5.2  TERMINATION FOR MATERIAL BREACH.  If either Party or a Subsidiary of
either Party commits a material breach with respect to any of such entity's
obligations hereunder, the other Party may give written notice to the allegedly
breaching Party or Subsidiary, specifying the alleged material breach and an
intention to terminate this Agreement and all extant licenses.  The Party or
Subsidiary, charged with the alleged material breach shall have sixty (60) days
from the date of receipt of such written notice to cure the alleged material

period, the other Party may terminate this Agreement and any license still in

the termination of this Agreement.

of any procedure for the settlement or postponement of debts or be the subject

be canceled immediately by the Party terminating this Agreement and such
breaching Party shall promptly forward to the other Party all copies of
Confidential Information, blue prints, drawings and data which it may have in
written or graphic or machine readable form and which have been proposed or
reproduced by it from the Confidential Information received from the other
Party.  The termination of this Agreement pursuant to Section 5.2 shall not

performance of either Party under this Agreement, whether or not such
circumstances are excused pursuant to Section 7.1 above, such Party shall, when
it first becomes aware of such circumstances, promptly notify the other Party,

     Electronics and Technologies further desire to delineate their respective
trademark rights on a worldwide basis.

                                   AGREEMENT

     NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth below, the parties hereby agree as follows.

     1.   ASSIGNMENT OF MARKS.

          Electronics hereby assigns to Technologies all right, title, and
interest which it may have in and to the marks set forth in Schedule A (the
"Marks"), together with the goodwill of the business symbolized by the Marks.
Electronics will, at Technologies' expense, execute such further instruments and
take such further actions as may be necessary or appropriate to further effect,
evidence and record such assignments as necessary with governmental agencies.

     2.   DISCLAIMER OF WARRANTY.

          All Marks assigned pursuant to this Agreement are assigned "as-is"
with respect to any trademark, service mark, trade name, or other designation
subject to this Agreement.  Electronics makes no representation or warranty, and

service mark, trade name or other designation; (3) the registrability of any
term, designation, or other symbol as a trademark or service mark; (4) non-
infringement; or (5) any other right or interest pertaining to any trademark,
service mark, trade name, or other designation.

     3.  CONSENT TO OTHER PARTY'S USE OF BEI MARKS AND NAMES.

          3.1  Technologies may use or register, or attempt to register any
trademark, service mark, trade name, or other designation containing or
comprising the term BEI, or any

                                       2

transliteration or translation thereof, throughout the world in connection with
(1) electronic devices and equipment used in non-medical applications and (2)
services related to the sale or use of those goods (the "Technologies

          3.2  Electronics may use, register, or attempt to register any

sale or use of those goods (the "Electronics Medical Business").

          3.3  Technologies will not use, register or attempt to register
anywhere in the world:

          The BEI Triangular logo shown in Schedule B or any mark, logo or
designation confusingly similar thereto, provided that it may use the BEI
Rectangular logo shown in Schedule C without restriction;

          Any trademark, service mark, trade name or other designation
containing or comprising the term BEI in combination with the word "Medical" or
other term connoting the medical or health care fields or any transliteration or

          Any trademark, service mark, trade name or other designation

of, or attempt to register, any trademark, service mark, trade name, or other

3.4 herein.

          3.6  Electronics will not challenge Technologies' use of, registration
of, or attempt to register, any trademark, service mark, trade name, or other
designation comprising or containing the term BEI or any transliteration or
translation thereof in connection with the Technologies Business, unless such

herein.

          3.7  Neither party may use any trade name comprising the term BEI or
any transliteration or translation thereof solely in combination with any
geographic term to identify its business, goods, or services where doing so
would be likely to cause confusion with the other party.

          3.8  The parties will cooperate with each other as needed in providing
evidence of the consents given herein or otherwise in effecting trademark,
service mark, or business name registration or for other purposes for which such
evidence may be needed consistent with the terms of this Agreement.

          3.9  The parties believe that there is not likely to be confusion as
to their respective products or businesses if each party complies with the
foregoing terms governing use or registration of marks and names. In the event
such confusion occurs, the parties will cooperate as necessary and use all
commercially reasonable efforts to promptly resolve any such confusion and, if
appropriate, to direct third parties to the correct party. The parties agree to
use all commercially reasonable efforts to correct mistakes appearing in the
communications media regarding their respective corporate or trade names,
trademarks, or service marks and to respond to oral inquiries regarding the
parties' corporate or trade names, trademarks, or service marks by stating, to
the extent necessary to correct mistakes or respond to an inquiry, accurate
information about the parties' respective businesses or products.

     4.   TERM AND TERMINATION.

          4.1  This Agreement shall be effective on the Effective Date.  The
consent provisions as set forth in Section 3 shall continue in perpetuity unless
terminated in accordance with the provisions of this Agreement.

          4.2  If either party discontinues all use of the mark BEI in the
ordinary course of trade everywhere in the world, including all use by
subsidiaries, affiliates, or licensees for the benefit of that party, for a
period of three consecutive years, the limitations on the other party's use of
the mark BEI in Paragraph 3.3 or Paragraph 3.4 of this Agreement, as the case
may be, shall terminate.

          6.1  In the event that either party breaches any of its obligations
under this Agreement, the party claiming breach shall give notice in writing to
the other party.  If the breach is curable, the party claimed to have breached
the Agreement shall have 45 days to cure the breach before the party claiming
the breach may bring legal action.  Any statute of limitation governing such
claim shall be tolled pending the cure period.  Notwithstanding the foregoing,
where a party reasonably believes that a breach of an obligation under this
Agreement may result in immediate, irreparable harm, the party shall be entitled
to seek injunctive relief first.

     7.   ATTORNEYS' FEES AND COSTS.

          In the event either party hereto shall bring any action to enforce any
rights hereunder, the prevailing party in such action shall be entitled, in

writing signed by both parties.

     12.  SEVERABILITY.

          In the event any one or more of the provisions contained in this
Agreement should be held invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein and therein shall not in any way be affected or impaired thereby.  The

party, which consent shall not be unreasonably withheld, except to: a Subsidiary
of a party, or a successor to the business of such party to which this Agreement
relates, or a successor to all or substantially all of the assets of such party,
provided that the successor agrees in writing to accept the rights and to be
bound by the obligations of the assigning party, any other assignment being
void.

          13.2  VIOLATION. Any assignment in violation of this Section 13 shall
be void and any attempt to assign or actual assignment in derogation of this
prohibition shall be a material breach of this Agreement.

     14.  THIRD PARTY BENEFICIARIES.

          This Agreement is solely for the benefit of the parties hereto and
their respective Subsidiaries and should not be deemed to confer upon third
parties any remedy, claim, liability, reimbursement, claim of action or other
right in excess of those existing without reference to this Agreement.

     15.  FORCE MAJEURE.

          15.1 ACTS CONSTITUTING FORCE MAJEURE. Neither party shall be liable to
the other for a delay in its performance of this Agreement arising from causes
beyond its reasonable control. Without limiting the generality of the foregoing,
such events include any act of God; accident; explosion; fire; earthquake;
flood; strikes; labor disputes; riots; sabotage; embargo; equipment failure;
federal, state, or local legal restriction or limitation. Neither party shall be
required to resolve labor disputes, but shall use commercially reasonable
efforts to seek alternative sources to the extent practicable.

          15.2 NOTICE REQUIREMENT. When circumstances occur that delay the
performance of either party under this Agreement, whether or not such
circumstances are excused pursuant to Section 15.1 above, such party shall, when
it first becomes aware of such circumstances, promptly notify the other party,
by facsimile or by telephone confirmed in writing within two (2) business days
in the case of oral notice. Within ten (10) business days of the date when
either party first becomes aware of the event which it contends is responsible
for the delay, it shall supply to the other party in writing the reason(s) for
and anticipated duration of such delay, the measures taken and to be taken to
prevent or minimize the delay, and the timetable for the implementation of such
measures.

To the Purchasers named in Schedule I
  to this Agreement

Gentlemen:

     Reference is made to the Note Agreement dated as of August 15, 1993 (the
"Original Note Agreement"), among BEI Electronics, Inc., a Delaware corporation
("Electronics"), and each of you (the "Purchasers"), as amended by First
Amendment to Note Agreement dated as of April 1, 1994, Second Amendment to Note
Agreement dated as of September 30, 1994, Third Amendment to Note Agreement
dated as of December 29, 1995, and Fourth Amendment to Note Agreement dated as
of March 27, 1997 (as so amended, the "Note Agreement"), under and pursuant to
which Electronics issued and sold and you (and your predecessor as a holder of
some of the Original Notes referred to below) purchased an aggregate original
principal amount of $16,800,000 6.73% Series A Senior Notes due October 1, 2000,
and an aggregate original principal amount of $11,200,000 6.73% Series B Senior
Notes due November 15, 2000 (respectively, the "Original Series A Notes" and the
"Original Series B Notes" and collectively, the "Original Notes").

     Electronics has now formed a new subsidiary, the undersigned BEI
Technologies, Inc., a Delaware corporation ("Technologies" or the "Company"),
which will principally operate Electronics' established sensors and systems
business, and Electronics intends to distribute all of the common stock of
Technologies to the holders of the common stock of Electronics on a pro rata
basis, all as described in the Preliminary Registration Statement on Form 10
filed by Electronics with the Securities and Exchange Commission on July 2,
1997, 
<PAGE>
 
BEI Technologies, Inc.                                      Assumption Agreement

as amended (the "Preliminary Registration Statement").  The transaction
described in the Preliminary Registration Statement is herein sometimes referred
to as the "Spin-off".

     Electronics and Technologies have proposed that, concurrently with the
consummation of the Spin-off, the Note Agreement will be amended and restated as
herein set forth; the Original Notes will be amended to increase the interest
rate thereon to 7.23% per annum; Technologies will assume the indebtedness
evidenced by the Original Notes, as so amended, and the obligations of
Electronics under the Note Agreement, as so amended and restated; Technologies
will issue its Notes described in Section 1 hereof in exchange for the surrender
by you for cancellation of the Original Notes; and Electronics will be released
and discharged from its obligations and liabilities under the Note Agreement and
the Original Notes.  Based on the representations and warranties and subject to
the satisfaction of the conditions precedent hereinafter set forth, by your
execution and delivery hereof you accept such proposition of Electronics and
Technologies and you further waive any Default or Event of Default arising under
the Note Agreement as a result of the Spin-off.

  Section 1.3.  Several Obligations. The obligations of each Purchaser shall be
  ---------------------------------
several and not joint and no Purchaser shall be liable or responsible for the
acts of any other Purchaser.

SECTION 2. PREPAYMENT OF NOTES.

  Section 2.1.  Required Prepayments.
  ----------------------------------
     (a) Series A Notes.  On October 1 in each year, commencing October 1, 1997
         --------------
  and ending October 1, 1999, both inclusive, the Company will prepay and apply
  and there shall become due and payable on the principal indebtedness evidenced
  by the Series A Notes an amount equal to the lesser of (i) $3,360,000 and (ii)
  the principal amount of the Series A Notes then outstanding. The entire
  remaining principal amount of the Series A Notes shall become due and payable
  on October 1, 2000.

     (b) Series B Notes.  On November 15 in each year, commencing November 15,
         --------------
  1997 and ending November 15, 1999, both inclusive, the Company will prepay and

  evidenced by the Series B Notes an amount equal to the lesser of (i)

                                      -3-
<PAGE>
 
BEI Technologies, Inc.                                      Assumption Agreement

  The entire remaining principal amount of the Series B Notes shall become due
  and payable on November 15, 2000.

No premium shall be payable in connection with any required prepayment made
pursuant to this (S)2.1.  For purposes of this (S)2.1, any prepayment of less
than all of the outstanding Notes of any Series pursuant to (S)2.2 shall be
deemed to be applied first, to the amount of principal scheduled to remain
unpaid at the maturity of such Series, and then to the remaining scheduled
principal payments on the Notes of such Series in inverse chronological order.

     In the event of any purchase or other acquisition by the Company or
Electronics or by any Subsidiary or Affiliate of the Company or Electronics of
less than all of the Notes of either Series, the amount of the payments required
at maturity and each prepayment required to be made pursuant to this (S)2.1 on
the Notes of such Series shall be reduced in the proportion that the principal
amount of such purchase or other acquisition bears to the unpaid principal
amount of the Notes of such Series immediately prior to such purchase or other
acquisition (after giving effect to any prepayment of the Notes of such Series
made pursuant to this (S)2.1 on the date of such purchase or other acquisition).

  Section 2.2.  Optional Prepayment with Premium. In addition to the payments
  ----------------------------------------------
required by (S)2.1, upon compliance with (S)2.3 the Company shall have the
privilege, at any time and from time to time, of prepaying the outstanding
Notes, either in whole or in part (but if in part then in a minimum principal
amount of $100,000) by payment of the principal amount of the Notes, or portion
thereof to be prepaid, and accrued interest thereon to the date of such
prepayment, together with a premium equal to the Make-Whole Amount, determined
as of three business days prior to the date of such prepayment pursuant to this
(S)2.2.

  Section 2.3.  Notice of Optional Prepayments. The Company will give notice of
  --------------------------------------------
any prepayment of the Notes pursuant to (S)2.2 to each Holder not less than 30
days nor more than 60 days before the date fixed for such optional prepayment
specifying (i) such date, (ii) the principal amount of the Holder's Notes to be
prepaid on such date, (iii) that a premium may be payable, (iv) the date when
such premium will be calculated, (v) the estimated premium, and (vi) the accrued
interest applicable to the prepayment. Such notice of prepayment shall also
certify all facts, if any, which are conditions precedent to any such
prepayment. Notice of prepayment having been so given, the aggregate principal
amount of the Notes specified in such notice, together with accrued interest
thereon and the premium, if any, payable with respect thereto shall become due
and payable on the prepayment date specified in said notice. Not later than two
business days prior to the prepayment date specified in such notice, the Company
shall provide each Holder written notice of the premium, if any, payable in
connection with such prepayment and, whether or not any premium is payable, a
reasonably detailed computation of the Make-Whole Amount.

  Section 2.4. Application of Prepayments. All partial prepayments of the Notes
  ---------------------------------------
of either Series pursuant to (S)2.1 shall be allocated among all of the Notes of
such Series in accordance with the unpaid principal amounts thereof, and all
partial prepayments pursuant

                                      -4-
<PAGE>
 
BEI Technologies, Inc.                                      Assumption Agreement

to (S)2.2 shall be applied on all outstanding Notes of both Series ratably in
accordance with the unpaid principal amounts thereof.

  Section 2.5.  Direct Payment.  Notwithstanding anything to the contrary
  ----------------------------
contained in this Agreement or the Notes, in the case of any Note owned by any
Holder that is a Purchaser or any other Institutional Holder which has given
written notice to the Company requesting that the provisions of this (S)2.5
shall apply, the Company will punctually pay when due the principal thereof,
interest thereon and Make-Whole Amount, if any, due with respect to said
principal, without any presentment thereof, directly to such Holder at its
address set forth herein or such other address as such Holder may from time to
time designate in writing to the Company or, if a bank account with a United
States bank is so designated for such Holder, the Company will make such
payments in immediately available Federal funds to such bank account, marked for
attention as indicated, or in such other manner or to such other account in any
United States bank as such Holder may from time to time direct in writing.

SECTION 3. REPRESENTATIONS.

  Section 3.1. Representations of the Company. The Company represents and
  -------------------------------------------
warrants that all representations and warranties set forth in Exhibit B are true
and correct as of the date hereof and are incorporated herein by reference with
the same force and effect as though herein set forth in full.

  Section 3.2. Representations of the Purchasers. Each Purchaser (i) represents
  ----------------------------------------------
that it is an insurance company regulated as an insurer under the laws of a
jurisdiction within the United States of America, (ii) represents and in
entering into this Agreement the Company understands, that such Purchaser is
acquiring the Notes for the purpose of investment and not with a view to the
distribution thereof, and that such Purchaser has no present intention of
selling, negotiating or otherwise disposing of the Notes and (iii) acknowledges
that this Note has not been registered under the Securities Act of 1933, as
amended, or any state securities law, and may not be sold, assigned, transferred
or otherwise disposed of in the absence of an effective registration statement
under the Securities Act of 1933, as amended, and applicable state securities
laws, or an exemption from such registration; it being understood, however, that
the disposition of such Purchaser's property shall at all times be and remain
within its control. Such Purchaser further represents that the Original Notes to
be surrendered by it for cancellation are held in, and the Notes being acquired
by it are being acquired for, an "insurance company general account" within the
meaning of Department of Labor Prohibited Transaction Exemption 95-60 (issued
July 12, 1995) and there is no employee benefit plan, treating as a single plan,
all plans maintained by the same employer or employee organization, with respect
to which the amount of the general account reserves and liabilities for all
contracts held by or on behalf of such plan, exceeds ten percent (10%) of the
total reserves and liabilities of such general account (exclusive of separate
account liabilities) plus surplus, as set forth in the NAIC Annual Statement
filed with such Purchaser's state of domicile. As used in this (S)3.2, the terms
"employee benefit plan" and "separate account" shall have the respective
meanings assigned to such terms in Section 3 of ERISA.

  Section 4.2.  Waiver of Conditions.  If on the Closing Date the
  ----------------------------------
Company fails to tender to any Purchaser the Notes to be issued to such
Purchaser on such date or if the conditions specified in (S)4.1 have not been
fulfilled, such Purchaser may thereupon elect to be relieved of all further
obligations under this Agreement.  Without limiting the foregoing, if the
conditions specified in (S)4.1 have not been fulfilled, such Purchaser may waive
compliance by the Company with any such condition to such extent as such
Purchaser may in its sole discretion determine.  Nothing in this (S)4.2 shall
operate to relieve the Company of any of its obligations hereunder or to waive
any Purchaser's rights against the Company.

SECTION 5.    COMPANY COVENANTS.

     From and after the Closing Date and continuing so long as any amount
remains unpaid on any Note:

  Section 5.1. Corporate Existence, Etc. The Company will preserve and keep in
  -------------------------------------
full force and effect, and will cause each Restricted Subsidiary to preserve and
keep in full force and effect, its corporate existence and all licenses and
permits necessary to the proper conduct of its business; provided, however, that
                                                         --------  -------
the foregoing shall not prevent any transaction permitted by (S)5.13.

  Section 5.2. Insurance.  The Company will maintain, and will cause each 
  ----------------------
Restricted Subsidiary to maintain, insurance coverage by financially sound and
reputable insurers accorded a rating by A. M. Best Company, Inc. ("Best") of
A:XII or higher at the time of issuance of any such policy and in such forms and
amounts and against such risks as are 

                                      -7-
<PAGE>
 
BEI Technologies, Inc.                                      Assumption Agreement

customary for corporations of established reputation engaged in the same or a
similar business and owning and operating similar properties; provided, however,
that if during the term of any such insurance policy, the rating accorded the
insurer shall be less than A:XII, the Company, on the date of renewal of any
such policy (or, if such change in rating shall occur within 90 days prior to
such renewal date, within 90 days of the date of such change in rating), will
obtain such insurance policy from an insurer accorded such a rating; provided
                                                                     --------

Subsidiary, respectively, or upon or in respect of all or any part of the
property or business of the Company or such Restricted Subsidiary, all trade
accounts payable in accordance with usual and customary business terms, and all
claims for work, labor or materials, which if unpaid might become a Lien upon
any property of the Company or such Restricted Subsidiary; provided, however,
                                                           --------  -------
that the Company or such Restricted Subsidiary shall not be required to pay any
such tax, assessment, charge, levy, account payable or claim if (i) the
validity, applicability or amount thereof is being contested in good faith by
appropriate actions or proceedings which will prevent the forfeiture or sale of
any property of the Company or such Restricted Subsidiary or any material
interference with the use thereof by the Company or such Restricted Subsidiary,
and (ii) the Company or such Restricted Subsidiary shall set aside on its books,
reserves deemed by it to be adequate with respect thereto. The Company will

as amended, ERISA and all laws, ordinances, governmental rules and regulations
relating to environmental protection in all applicable jurisdictions, the
violation of which could materially and adversely affect the properties,
business, prospects, profits or condition of the Company and its Restricted
Subsidiaries or would result in any Lien not permitted under (S)5.9.

  Section 5.4. Maintenance, Etc. The Company will maintain, preserve and keep,

  Section 5.5.  Nature of Business.  Neither the Company nor any
  --------------------------------
Restricted Subsidiary will engage in any business (other than any activities
which are ancillary, incidental or necessary to the business engaged in by the
Company and its Restricted Subsidiaries on the date of the Spin-off) if, as a
result, the general nature of the business, taken on a

                                      -8-
<PAGE>
 
BEI Technologies, Inc.                                      Assumption Agreement

consolidated basis, which would then be engaged in by the Company and its
Restricted Subsidiaries would be substantially changed from the general nature
of the business engaged in by the Company and its Restricted Subsidiaries on the
date of the Spin-off.

  Section 5.6. Consolidated Adjusted Tangible Net Worth. The Company will at all
  -----------------------------------------------------
times keep and maintain a Consolidated Adjusted Tangible Net Worth at an amount

such sale, lease or other disposition, when added to the book value of all other

                                                                   --------

    any Person holding debt Securities of such Holder who shall have requested
    to inspect such information subject to the provisions of this paragraph (i);
    (v) the National Association of Insurance Commissioners; and (vi) any entity
    utilizing such information to rate or classify such Holder's debt or equity

Without limiting the foregoing, the Company will permit each Institutional
Holder (or such Persons as such Institutional Holder may designate), to visit
and inspect, under the Company's guidance, any of the properties of the Company
or any Restricted Subsidiary not requiring any level of official United States
Government security clearance, to examine all of their books of account, records
and reports, to make copies and extracts therefrom and to discuss their
respective affairs, finances and accounts with their respective officers and
independent public accountants (and by this provision the Company authorizes
said accountants to discuss with any Institutional Holder the finances and
affairs of the Company and its Restricted Subsidiaries) all at such reasonable
times and upon reasonable notice and as often as may be reasonably requested.
The Company shall not be required to pay or reimburse any such Institutional
Holder for expenses which any such Institutional Holder may incur in connection
with any such visitation or inspection, except that if such visitation or
inspection is made during any period when a Default or an Event of Default shall
have occurred and be continuing, the Company agrees to reimburse such
Institutional Holder for all such expenses promptly upon demand.

  Section 5.19.  Certain Changes in Accounting Principles.  In the
  -------------------------------------------------------
event a change after the date of this Agreement in (i) GAAP or (ii) any
regulation issued by the Securities and Exchange Commission (either such event
being referred to herein as an "Accounting Change"), which results in a material
change in the calculations of any financial covenant contained in (S)5 (the
"Affected Computation") in such a manner and to such an extent that, in the good
faith judgment of the Chief Financial Officer of the Company or the Holder or
Holders of not less than 50% of the unpaid principal amount of the Notes, as
evidenced by notice in writing from such Holder or Holders to the Company
(collectively, the "Holder Notice"), the application of the Accounting Change to
the Affected Computation would no longer reflect the intention of the parties to
the Agreements, then and in any such event:

       (a) the Company shall give written notice of such determination to the
  Holders promptly after making such determination or receiving a Holder Notice,
  which notice shall be accompanied by a copy of such Holder Notice or an

  the Company:

           (i) describing the Accounting Change in question and the particular
  covenant or covenants which will be affected by such Accounting Change;

           (ii) setting forth in reasonable detail (including detailed
  calculations) the manner and extent to which the covenant or covenants listed
  in the officer's certificate are affected by such Accounting Change; and

           (iii)  setting forth in reasonable detail (including detailed
  calculations) the information required in order to establish that the Company
  would be in compliance with the requirements of the covenant or covenants
  listed in the officer's certificate if such Accounting Change was not
  effective.

       (b) each Holder will enter into good faith negotiations with the Company
  for an equitable amendment of such covenant or covenants pursuant to (S)7 so
  as to place the parties, insofar as possible, in the same relative position as
  if such Accounting Change had not occurred; and

       (c) for the period from the date on which such Accounting Change becomes
  effective (the "Effective Date") to the effective date of an amendment to this
  Agreement pursuant to (S)7, the Company shall be deemed to be in compliance
  with the covenant or covenants listed in the officer's certificate if and so
  long as the Company would be in compliance with such covenant or covenants if
  such Accounting Change had not occurred, and if no amendment to this Agreement
  has become effective within 90 days after the Effective Date of such
  Accounting Change, then all accounting computations required to be made for
  purposes of this Agreement thereafter shall be done in accordance with GAAP as
  in effect immediately prior to that Effective Date.

by any Holder; or

notice within three business days of such event to all Holders.

  Section 6.3. Acceleration of Maturities. When any Event of Default described

in paragraph (a), (b) or (c) of (S)6.1 has happened and is continuing, any

accrued interest on the Notes held by such Holder to be, and all such Notes
shall thereupon become, forthwith due and payable, without any presentation,
demand, protest or other notice of any kind, all of which are hereby expressly

course of dealing on the part of a Holder nor any delay or failure on the part
of any Holder to exercise any right shall operate as a waiver of such right or
otherwise prejudice such Holder's rights, powers and remedies. The Company
further agrees, to the extent permitted by law, to pay to each Holder all costs
and expenses incurred by it in the collection of any Notes upon any default
hereunder or thereon, including

  Average Life to Maturity and for the published maturity next shorter than the
  Weighted Average Life to Maturity shall be interpolated from such yields on a
  straight-line basis, rounding in each of such relevant periods to the nearest
  month.

financial position or cash flows for such period.

                    (b) Since September 28, 1996, there has been no change in
        the condition, financial or otherwise, of the businesses to comprise the
        Company and its consolidated Subsidiaries as shown on the combined
        balance sheet as of such date except changes in the ordinary course of
        business, none of which individually or in the aggregate has had a
        Material Adverse Effect.

          5.        Indebtedness.  Sections 5.7(b)(1) and B-5 of the Disclosure
                    ------------
Letter correctly describe all Current Debt, Funded Debt, Capitalized Leases and
Long-Term Leases of the Company and its Restricted Subsidiaries outstanding on
the Closing Date, giving effect to the consummation of the Spin-off.

          6.        Full Disclosure.  Neither the financial statements referred
                    ---------------
to in paragraph 4 hereof nor the Agreement, the Preliminary Registration
Statement or any other written statement furnished by Electronics or
Technologies to such Purchaser in connection with the negotiation of the
issuance of the Notes, contains any untrue statement of a material fact or omits
a material fact necessary to make the statements contained therein or herein not
misleading.  There is no fact peculiar to the Company or its Subsidiaries which
Electronics or Technologies has not disclosed to such Purchaser in writing which
materially affects adversely nor, so far as Technologies can now foresee, will
have a Material Adverse Effect.

          7.        Pending Litigation.  Except as disclosed in Section B-7 of
                    ------------------
the Disclosure Letter, there are no proceedings pending or, to the knowledge of
the Company, threatened against or affecting the Company or any Restricted
Subsidiary in any court or before any governmental authority or arbitration
board or tribunal which would reasonably be expected to result in a Material
Adverse Effect.

          8.        Title to Properties.  The Company and each Restricted
                    -------------------
Subsidiary has good and marketable title in fee simple (or its equivalent under
applicable law) to all material parcels of real property and has good title to
all the other material items of property it purports to own, including that
reflected in the most recent balance sheet referred to in paragraph 4 hereof,
except as sold or otherwise disposed of in the ordinary course of business and
except for Liens permitted by the Agreement.

          9.        Patents and Trademarks.  The Company and each Restricted
                    ----------------------
Subsidiary owns or possesses all the patents, trademarks, trade names, service
marks, copyright, licenses and rights with respect to the foregoing necessary
for the present and planned future conduct of its business, without any known
conflict with the rights of others, which failure to own or possess would have a
Material Adverse Effect.

          10.       Sale is Legal and Authorized.  The issuance of the Notes by
                    ----------------------------
the Company and compliance by the Company with all of the provisions of the
Agreement and the Notes --

                    (a) are within the corporate powers of the Company;

                    (b) will not violate any provisions of any law or any order
        of any court or governmental authority or agency and will not conflict
        with or result in any breach of any of the terms, conditions or
        provisions of, or constitute a default under the Certificate of
        Incorporation or By-laws of the Company or any indenture or other
        agreement or instrument to which the Company is a party or by which it
        may be bound or result in the imposition of any Liens or encumbrances on
        any property of the Company; and

                    (c) have been duly authorized by proper corporate action on
        the part of the Company (no action by the stockholders of the Company
        being required by law, by the Certificate of Incorporation or By-laws of
        the Company or otherwise). The Agreement has been duly executed and
        delivered by the Company and constitutes the legal, valid and binding
        obligation, contract and agreement of the Company enforceable in
        accordance with its terms. On the Closing Date the Notes will have been
        duly executed and delivered by the Company and will constitute the
        legal, valid and binding obligations of the Company enforceable in
        accordance with their respective terms.

          11.       No Defaults.  No Default or Event of Default has occurred
                    -----------
and is continuing.  The Company is not in default in the payment of principal or
interest on any Funded Debt or Current Debt and is not in default under any
instrument or instruments or agreements under and subject to which any Funded
Debt or Current Debt has been issued, and no event has occurred and is
continuing under the provisions of any such instrument or agreement which with
the lapse of time or the giving of notice, or both, would constitute an event of
default thereunder.

          12.       Governmental Consent.  No approval, consent or withholding
                    --------------------
of objection on the part of any regulatory body, state, Federal or local, is
necessary in connection with the Spin-off or the execution and delivery by the
Company of the Agreement or the Notes or compliance by the Company with any of
the provisions of the Agreement or the Notes.

          13.       Taxes.  All tax returns required to be filed by the Company
                    -----
or any Restricted Subsidiary and their respective predecessors in any
jurisdiction have, in fact, been filed, and all taxes, assessments, fees and
other governmental charges upon the Company or any Restricted Subsidiary or
their respective predecessors or upon any of their respective properties, income
or franchises, which are shown to be due and payable in such returns have been
paid.  For all taxable years ending on or before ______________, the Federal
income tax liability of Electronics and its Subsidiaries has been satisfied and
either the period of limitations on assessment of additional Federal income tax
has expired or Electronics and its Subsidiaries have entered into an agreement
with the Internal Revenue Service closing conclusively the total tax liability
for the taxable year.  Technologies does 

                                      -3-
<PAGE>
 
not know of any proposed additional tax assessment against it for which adequate
provision has not been made on its accounts, and no material controversy in
respect of additional Federal or state income taxes due since said date is
pending or to the knowledge of the Company threatened. The provisions for taxes
on the books of the Company and each Restricted Subsidiary are adequate for all
open years, and for its current fiscal period.

          14.       Private Offering.  Neither the Company, directly or
                    ----------------
indirectly, nor any agent on its behalf has offered or will offer the Notes or
any similar Security or has solicited or will solicit an offer to acquire the
Notes or any similar Security from or has otherwise approached or negotiated or
will approach or negotiate in respect of the Notes or any similar Security with
any Person other than the Purchasers. Neither the Company, directly or
indirectly, nor any agent on its behalf has offered or will offer the Notes or
any similar Security or has solicited or will solicit an offer to acquire the
Notes or any similar Security from any Person so as to bring the issuance and
sale of the Notes within the provisions of Section 5 of the Securities Act of
1933, as amended.

          15.       ERISA.  The consummation of the Spin-off and of the
                    -----
transactions provided for in the Agreement and compliance by the Company with
the provisions thereof and the Notes issued thereunder will not involve any
prohibited transaction within the meaning of ERISA or Section 4975 of the
Internal Revenue Code of 1986, as amended.  Each Plan complies in all material
respects with all applicable statutes and governmental rules and regulations,
and (a) no Reportable Event has occurred and is continuing with respect to any
Plan, (b) neither the Company nor any ERISA Affiliate has withdrawn from any
Plan or Multiemployer Plan or instituted steps to do so, and (c) no steps have
been instituted to terminate any Plan.  No condition exists or event or
transaction has occurred in connection with any Plan which could result in the
incurrence by the Company or any ERISA Affiliate of any material liability, fine
or penalty.  No Plan maintained by the Company or any ERISA Affiliate, nor any
trust created thereunder, has incurred any "accumulated funding deficiency" as
defined in Section 302 of ERISA nor does the present value of all benefits
vested under all Plans exceed, as of the last annual valuation date, the value
of the assets of the Plans allocable to such vested benefits by an amount
greater than (i) $1,000,000 in the aggregate.  Neither the Company nor any ERISA
Affiliate has any contingent liability with respect to any post-retirement
"welfare benefit plan" (as such term is defined in ERISA) except as has been
disclosed to the Purchasers or which would not have a Material Adverse Effect.

          16.       Compliance with Law.  Neither the Company nor any Restricted
                    -------------------
Subsidiary (a) is in violation of any law, ordinance, franchise, governmental
rule or regulation to which it is subject; or (b) has failed to obtain any
license, permit, franchise or other governmental authorization necessary to the
ownership of its property or to the conduct of its business, which violation or
failure to obtain would have a Material Adverse Effect or impair the ability of
the Company to perform its obligations contained in the Agreement or the Notes.
Neither the Company nor any Restricted Subsidiary is in default with respect to
any order of any court or governmental authority or arbitration board or
tribunal.

          17.       Compliance with Environmental Laws.  Except as set forth in
                    ----------------------------------
paragraph 6 of Section B-7 of the Disclosure Letter, the Company is not in
violation of any applicable 

                                      -4-
<PAGE>
 
Federal, state, or local laws, statutes, rules, regulations or ordinances
relating to public health, safety or the environment, including, without
limitation, relating to releases, discharges, emissions or disposals to air,
water, land or ground water, to the withdrawal or use of ground water, to the
use, handling or disposal of polychlorinated biphenyls (PCBs), asbestos or urea
formaldehyde, to the treatment, storage, disposal or management of hazardous
substances (including, without limitation, petroleum, crude oil or any fraction
thereof, or other hydrocarbons), pollutants or contaminants, to exposure to
toxic, hazardous or other controlled, prohibited or regulated substances which
violation could have a material adverse effect on the business, prospects,
profits, properties or condition (financial or otherwise) of the Company and its
Restricted Subsidiaries, taken as a whole. The Company does not know of any
liability or class of liability of the Company or any Restricted Subsidiary
under the Comprehensive Environmental Response, Compensation and Liability Act
of 1980, as amended (42 U.S.C. Section 9601 et seq.), or the Resource
                                            -- ---
Conservation and Recovery Act of 1976, as amended (42 U.S.C. Section 6901 et

seq.) which would have a Material Adverse Effect.

               DESCRIPTION OF SPECIAL COUNSEL'S CLOSING OPINION

        The closing opinion of Chapman and Cutler, special counsel to the
Purchasers, called for by (S)4.1 of the Assumption Agreement in connection with
the Closing Date, shall be dated the Closing Date and addressed to the
Purchasers, shall be satisfactory in form and substance to the Purchasers and
shall be to the effect that:

          1.             The Company is a corporation, validly existing and in
        good standing under the laws of the State of Delaware and has the
        corporate power and the corporate authority to execute and deliver the
        Assumption Agreement and to issue the Notes.

          2.             The Assumption Agreement has been duly authorized by
        all necessary corporate action on the part of the Company, has been duly
        executed and delivered by the Company and constitutes the legal, valid
        and binding agreement of the Company enforceable in accordance with its
        terms, subject to bankruptcy, insolvency, fraudulent conveyance and
        similar laws affecting creditors' rights generally, and general
        principles of equity (regardless of whether the application of such
        principles is considered in a proceeding in equity or at law).

          3.             The Notes have been duly authorized by all necessary
        corporate action on the part of the Company, and the Notes being
        delivered on the Closing Date have been duly executed and delivered by
        the Company and constitute the legal, valid and binding obligations of
        the Company enforceable in accordance with their terms, subject to
        bankruptcy, insolvency, fraudulent conveyance and similar laws affecting
        creditors' rights generally, and general principles of equity
        (regardless of whether the application of such principles is considered
        in a proceeding in equity or at law).

          4.             The issuance and delivery of the Notes issued on the
        Closing Date under the circumstances contemplated by the Assumption
        Agreement do not, under existing law, require the registration of the
        Notes under the Securities Act of 1933, as amended, or the qualification
        of an indenture under the Trust Indenture Act of 1939, as amended.

        The opinion of Chapman and Cutler shall also state that the opinion of
Cooley Godward LLP is satisfactory in scope and form to Chapman and Cutler and
that, in their opinion, the Purchasers are justified in relying thereon.

        In rendering the opinion set forth in paragraph 1 above, Chapman and
Cutler may rely solely upon an examination of the Certificate of Incorporation
of the Company certified by, and a certificate of good standing of the Company
from, the Secretary of State of the State of Delaware and the By-laws of the
Company.

        With respect to matters of fact upon which such opinion is based,
Chapman and Cutler may rely on appropriate certificates of public officials and
officers of the Company.

                                   EXHIBIT C
                           (to Assumption Agreement)
<PAGE>
 
                        DESCRIPTION OF CLOSING OPINION
                           OF COUNSEL TO THE COMPANY

          The closing opinion of Cooley Godward LLP, counsel for the Company,
which is called for by  (S)4.1 of the Assumption Agreement in connection with
the Closing Date, shall be dated the Closing Date and addressed to the
Purchasers, shall be satisfactory in scope and form to the Purchasers and shall
be to the effect that:

          We have acted as counsel to BEI Technologies, Inc., a Delaware
corporation (the "Company"), in connection with the Assumption Agreement and the
Notes.  This opinion is rendered to you in compliance with Section 4.1(b) of the
Assumption Agreement.  Capitalized terms used herein without definition have the
same meanings as in the Assumption Agreement.

          In our capacity as such counsel, we have examined originals, or copies
identified to our satisfaction as being true copies, of such records, documents
or other instruments as in our judgment are necessary or appropriate to enable
us to render the opinions expressed below.  These records, documents and
instruments included the following:

                       A.  The Certificate of Incorporation of the Company, as
        amended to date;

                       B.  The Bylaws of the Company, as amended to date;

                       C.  The records of proceedings and actions of the Board
        of Directors of the Company relating to the Assumption Agreement and the
        transactions contemplated thereby;

                       D.  The Assumption Agreement;

                       E.  The Notes; and

                       F.  The contracts, agreements and instruments involving
        the borrowing of money to which the Company is subject or by which the
        Company or any of its assets are bound, identified to us by responsible
        officers of the Company as being all of such agreements material to the
        Company (the "Material Agreements").

          With your consent, in connection with this opinion, we have examined
and relied upon the representations and warranties of the Purchasers as to
factual matters contained in and made pursuant to the Assumption Agreement and
upon originals or copies certified to our satisfaction of such records,
documents, certificates, opinions, memoranda and other instruments as in our
judgment are necessary or appropriate to enable us to render the opinion
expressed below.

          In rendering this opinion, we have assumed the genuineness and
authenticity of all signatures on original documents (other than the signatures
of the Company on the Assumption Agreement and the Notes); the authenticity of
all documents submitted to us as 

                                   EXHIBIT D
                           (to Assumption Agreement)
<PAGE>
 
originals; the conformity to originals of all documents submitted to us as
copies; the accuracy, completeness and authenticity of certificates of public
officials; and the due authorization, execution and delivery of all documents
(except the due authorization, execution and delivery by the Company of the
Assumption Agreement and the Notes) where authorization, execution and delivery
are prerequisites to the effectiveness of such documents. We have also assumed
that all individuals executing and delivering documents in their individual
capacity had the legal capacity to so execute and deliver; that the Assumption
Agreement is an obligation binding upon you; and that there are no extrinsic
agreements or understandings among the parties to the Assumption Agreement that
would modify or interpret the terms of the Assumption Agreement or the
respective rights or obligations of the parties thereunder.

          Our opinion is expressed with respect only to United States federal
law, the laws of the State of California (without regard to laws regarding
choice of applicable law) and the General Corporation Law of the State of
Delaware.  We express no opinion as to whether the laws of any particular
jurisdiction apply.

          With regard to our opinion in paragraph III below, we have, with your
permission, assumed that Illinois law is same in all material respects as
California law.

          Except as set forth in paragraphs IV and VI, we express no opinion
relative to the applicability or effect of any law, rule or regulation relating
to securities or to the sale or issuance thereof.

          With regard to our opinion in paragraph V below with respect to
conflicts, breaches or defaults under the Material Agreements, we have relied
solely upon (a) inquiries of officers of the Company, (b) a list supplied to us
by the Company, a copy of which has been supplied to your counsel, Chapman and
Cutler, of the Material Agreements, and (c) an examination of the items on the
aforementioned list; we have made no further investigation.

          We express no opinion as to the applicability or effect of any rule or
regulation relating to fraudulent transfers.

          On the basis of the foregoing, and in reliance thereon, we are of the
opinion that:

          I.             The Company is a corporation duly organized, validly
        existing and in good standing under the laws of Delaware and has all
        requisite corporate power and authority to execute and perform the
        Assumption Agreement and to issue the Notes and to own and operate its
        properties and to carry on business and is duly qualified as a foreign
        corporation to do business in California.

          II.            The Assumption Agreement and the Notes have been duly
        authorized by all necessary corporate action on the part of the Company,
        and have been duly executed and delivered by the Company and constitute
        the legal, valid and binding obligations of the Company, enforceable
        against the Company in accordance with their respective terms, except as
        enforceability may be subject to or limited by (i) general 

                                      D-2
<PAGE>
 
        equity principles and to limitations on the availability of equitable
        relief including specific performance; (ii) the effect of applicable
        bankruptcy, insolvency, reorganization, moratorium or other laws
        relating to or affecting the rights of creditors generally; and (iii)
        limitations on a borrower's ability to waive rights or benefits given by
        statute or otherwise, but in our view such limitations will not, subject
        to the other exceptions, qualifications and limitations in this letter,
        render the Assumption Agreement or the Notes invalid as a whole or
        substantially interfere with the realization of the principal benefits
        provided by the Assumption Agreement and the Notes.

          III.           No governmental consents, approvals, authorizations,
        registrations, declarations or filings on the part of the Company are
        required under United States federal law or the laws of the State of
        California for the due execution and delivery by the Company of the
        Assumption Agreement or the Notes.

          IV.            The issuance of the Notes issued on the date hereof and
        the execution, delivery and performance by the Company of the Assumption
        Agreement do not conflict with or result in any breach of any of the
        provisions of or constitute a default under or result in the creation or
        imposition of any Lien upon any of the property of the Company pursuant
        to the provisions of its Certificate of Incorporation or bylaws or any
        of the Material Agreements.

          VI.            The offer and issuance of the Notes is exempt from the
        registration requirements of the Securities Act of 1933, as amended, and
        does not require the qualification of an indenture under the Trust
        Indenture Act of 1939, as amended.

          VII.  The Spin-off has been consummated.

        This opinion is rendered only to the Purchasers and is solely for
their benefit in connection with the above transactions.  This opinion may not
be relied upon by any other person, firm or corporation for any purpose without
our prior written consent.  You may, however, deliver a copy of this opinion to
transferees of the Notes in connection with such transfer and they may rely upon
it as if it were addressed and had been delivered to them on the date hereof.

                                   THE LOANS

         2.1    The Revolving Loans.
                ------------------- 

                (a) The Revolving Commitment. Each Lender agrees, severally and
                    ------------------------
not jointly, on the terms and conditions hereinafter set forth, to make loans
("Revolving Loans") to the Borrowers from time to time during the period from
  ---------------                                                            
the date hereof to and including the Maturity Date in an aggregate amount not to
exceed the amount set opposite such Lenders name on the signature pages hereof,
as such amount may be reduced pursuant to Sections 2.1(c).  Each borrowing under
this Section 2.1(a) (a "Borrowing") shall be in a minimum amount of $500,000 or
                        ---------                                              
in an integral multiple of $100,000 in excess hereof; provided that a Eurodollar
Rate Loan shall be in a minimum amount of $1,000,000 or in an integral multiple
of $1,000,000 in excess hereof.  Each Borrowing shall be made on the same day by
the Lenders ratably according to their respective Commitments.  Within the
limits of the Revolving Commitment and prior to the Maturity Date, the Borrowers
may borrow, repay pursuant to Section 2.2(b) and reborrow under this Section;
provided that at no time shall the sum of (i) the aggregate principal amount of
outstanding Revolving Loans plus (ii) the Letter of Credit Usage exceed the
                            ----                                           
Available Revolving Commitment at such time.

                (b)  Making the Revolving Loans.
                     -------------------------- 

                     (i) The Borrowers may borrow under the Revolving Commitment
on any Business Day if the Borrowing is to consist of a Base Rate Loan and on
any Eurodollar Business Day if the Borrowing is to consist of a Eurodollar Rate
Loan. Whenever the Borrowers desire that the Lenders make Revolving Loans
hereunder they shall deliver an irrevocable Notice of Borrowing to the Agent no
later than 12:30 P.M., New York time, (i) three (3) Eurodollar Business Days
prior to the requested Borrowing date in the case of a Eurodollar Rate Loan and
(ii) on or before the requested Borrowing date in the case of a Base Rate Loan,
specifying (A) the amount of the proposed Borrowing, (B) the requested date of
the Borrowing, (C) whether the Borrowing is to consist of a Eurodollar Rate Loan
or a Base Rate Loan, (D) if the

                                      15
<PAGE>
 
Loan is to be a Eurodollar Rate Loan, the length of the Interest Period
therefor, (E) the Borrower or Borrowers that are to receive the proceeds of such
Borrowing and (F) the amount of proceeds to be received by each such Borrower.
Promptly following receipt of such notice, the Agent shall notify each Lender of
the date of the Loan, whether the Loan will be a Base Rate Loan or a Eurodollar
Rate Loan, the amount of that Lender's pro rata share of the Loan and, if the
Loan is a Eurodollar Rate Loan of the applicable Interest Period.  Not later
than 2:00 P.M., New York time, on the date specified for any Loan, each Lender
shall deposit immediately available funds in the amount of its pro rata share of
the Loan to the account of the Agent set forth on the signature pages hereof.
Upon satisfaction of the applicable conditions set forth in Article IV, the
Agent will make available the proceeds of all such Loans to the applicable
Borrower or Borrowers by crediting the account of such Borrower or Borrowers on
the books of the Agent, or as otherwise directed by such Borrower or Borrowers.

                     (ii) The Notice of Borrowing may be given by telex or
facsimile transmission or telephonically; provided, however, that the Borrowers
shall promptly deliver to the Agent an original written Notice of Borrowing
initially given telephonically. Any conflict regarding a notice or between an
oral notice and a written notice applicable to the same Borrowing shall be
conclusively determined by the Agent's books and records. The Agent shall not
incur any liability to the Borrowers in acting upon any notice of Borrowing
which the Agent believes reasonably and in good faith to have been given by a
Person duly authorized to borrow on behalf of any of the Borrowers.

                     (iii) Unless the Agent shall have received notice from
a Lender prior to the date of any Borrowing that such Lender will not make
available to the Agent such Lender's ratable portion of such Borrowing, the
Agent may assume that such Lender has made such portion available to the Agent
on the date of such Borrowing in accordance with subsection (1) of this Section
2.1(b) and the Agent may, in reliance upon such assumption, make available to
the applicable Borrower or Borrowers on such date a corresponding amount.  If
and to the extent that such Lender shall not have so made such ratable portion
available to the Agent, such Lender and the applicable Borrower or Borrowers
severally agree to repay to the Agent forthwith on demand such corresponding
amount together with interest thereon, for each day from the date such amount is
made available to the applicable Borrower or Borrowers until the date such
amount is repaid to the Agent, at (i) in the case of a Borrower, the interest
rate applicable at the time to such Borrowing and (ii) in the case of such
Lender, the Federal Funds Rate.  If such Lender shall repay to the Agent such
corresponding amount, such amount so repaid shall constitute such Lender's pro
rata share of such Borrowing for purposes of this Agreement.  The failure of any
Lender to make available its pro rata share of any

                                      16
<PAGE>
 
Borrowing shall not relieve any other Lender of its obligation, if any,
hereunder, to make available its pro rata share of such Borrowing on the date of
such Borrowing, but no Lender shall be responsible for the failure of any other
Lender to make available its pro rata share of any Borrowing on the date of any
Borrowing.


          (c) Voluntary Reduction of the Revolving Commitment.  The Borrowers
              -----------------------------------------------                
shall have the right, upon at least two (2) Business Days' written notice to the
Agent, to terminate in whole or reduce in part the unused portion of the
Revolving Commitment, without premium or penalty, provided that each partial
                                                  --------                  
reduction shall be in the aggregate amount of $1,000,000 or in an integral
multiple of $1,000,000 in excess thereof and that such reduction shall not
reduce the Revolving Commitment to an amount less than the amount outstanding
hereunder on the effective date of the reduction.

          (d) Revolving Notes.  The Revolving Loans made by the Lenders pursuant
              ---------------                                                   
hereto shall be evidenced by promissory notes of the Borrowers, substantially in
the form of Exhibit A, with any appropriate insertions (the "Revolving Notes"),
                                                             ---------------   
payable to the order of each Lender and representing the obligation of the
Borrowers to pay the aggregate unpaid principal amount of all Revolving Loans
made by that Lender, with interest thereon as prescribed in Section 2.3.  Each
Lender is hereby authorized to record in its books and records and on any
schedule annexed to its Revolving Note the date and amount of each Revolving
Loan made by that Lender, and the date and amount of each payment of principal
thereof, and any such recordation shall constitute prima facie evidence of the
                                                   ----- -----                
accuracy of the information so recorded; provided that failure by any Lender to
                                         --------                              
effect such recordation shall not affect the Borrowers' obligations hereunder.

          (e) Commitment Fee.  The Borrowers agree to pay to the Agent for the
              --------------                                                  
ratable benefit of the Lenders a commitment fee on the average daily unused
portion of the Revolving Commitment from the date hereof until the Maturity Date
at a rate equal to the Commitment Fee Percentage.  The Commitment Fee Percentage
shall be determined as provided in the Pricing Grid and may change for each
Pricing Period.  Such commitment fees shall be payable on each Interest Payment
Date, commencing on the first such date occurring after the date of this
Agreement, and on the Maturity Date.  For the purposes of calculating a
commitment fee, the Letter of Credit Usage shall be deemed a usage of the
Revolving Commitment.  The commitment fee shall be calculated on the basis of a
365 or 366 day year, as the case may be, for the actual days elapsed.

          (f) Other Fees.  The Borrowers shall pay to the Agent such other fees
              ----------                                                       
at such times as have been separately agreed to in writing between the parties.

          (a) Mandatory Repayments.  The aggregate principal amount of the
              --------------------                                        
Revolving Loans outstanding on the Maturity Date, together with accrued interest
thereon, shall be due and payable in full on the Maturity Date.

          (b) Optional Prepayments.  Any Borrower may at its option prepay the
              --------------------                                            
Loans, in whole or in part, at any time and from time to time, provided that,
                                                               --------      
with respect to the prepayment of any Eurodollar Rate Loan, the Agent shall have
received from such Borrower written notice of any such prepayment at least one
(1) Business Day prior to the date of the proposed prepayment if such date is
not the last day of the then current Interest Period for each Loan being
prepaid, in each case specifying the date and the amount of prepayment.  Partial
prepayments hereunder shall be in an aggregate principal amount of the lesser of
(a) $1,000,000 or any integral multiple of $100,000 in excess thereof and (b)
the outstanding balance of the Loan being prepaid.

          (c) Mandatory Prepayment.  If, at any time, the sum of the aggregate
              --------------------                                            
principal amount of outstanding Revolving Loans plus the Letter of Credit Usage
exceeds the Revolving Commitment then in effect, the Borrowers shall immediately
repay Revolving Loans in an amount equal to the excess; provided, however, that
                                                        --------  -------      
if after repayment pursuant to this subsection of all Revolving Loans then
outstanding, the Letter of Credit Usage shall exceed the Revolving Commitment
then in effect, the Borrowers shall immediately deliver to the Agent, to hold as
cash collateral as security for the obligations of the Borrowers to reimburse
the Issuing Bank for the amount of any drawings honored under any outstanding
Letters of Credit, an amount such that the Letter of Credit Usage minus that
                                                                  -----     
amount that is less than or equal to the Revolving Commitment then in effect;
                                                                             
provided that in lieu of furnishing such cash collateral as aforesaid, the

Borrowers may deliver outstanding Letters of Credit for cancellation, so that
the resulting Letter of Credit Usage is less than or equal to the Revolving
Commitment then in effect.  If, at any time after such cash collateral is
delivered to the Agent, the Revolving Commitment then in effect exceeds (i) the
aggregate principal amount of Revolving Loans outstanding (ii) the Letter of
Credit Usage minus the cash collateral delivered to the Agent, then a portion of
             -----                                                              
the cash collateral held by the Agent for the purposes described above shall be
paid to the Borrowers immediately, in the amount by which the Revolving
Commitment exceeds the sum of clauses (i) and (ii) specified above.  Any amount
delivered to the Agent pursuant to this Section shall be held in an interest
bearing account established by the Agent and any interest paid on such account
shall be paid by the Agent to the Borrowers promptly following receipt thereof
by the Agent; provided, however, that noting herein shall require the Agent to

principal amount of each Loan from the date of such Loan until the maturity
thereof, at one of the following rates per annum:

              (i) With respect to Base Rate Loans, at a rate per annum equal to
the Base Rate; and

              (ii) With respect to Eurodollar Rate Loans, at a rate per annum
equal at all times during each Interest Period for such Eurodollar Rate Loan to
the Eurodollar Rate for such Interest Period plus the Applicable Margin
                                             ----
therefor, as the Applicable Margin shall change from time to time.

    2.4   Continuation and Conversion Options.  Any Borrower may elect from time
          -----------------------------------                         
to time to convert its outstanding Loans from Loans bearing interest at a rate
determined by reference to one basis to Loans bearing interest at a rate
determined by reference to an alternative basis by giving the Agent (i)
irrevocable written notice in the form of a Notice of Conversion/Continuation of
an election to convert Eurodollar Rate Loans to Base Rate Loans and (ii) at
least three (3) Eurodollar Business Days' prior irrevocable written notice in
the form of a Notice of Conversion/Continuation of an election to convert Base
Rate Loans to Eurodollar Rate Loans, provided that any conversion of Eurodollar
                                     --------                                  
Rate Loans shall only be made on the last day of an Interest Period with respect
thereto, provided, further that no Loan may be converted to a Eurodollar Rate
         --------  -------                                                   
Loan so long as an Event of Default or Potential Event of Default has occurred
and is continuing.  Any Borrower may elect from time to time to continue its
outstanding Eurodollar Rate Loans upon the expiration of the Interest Period(s)
applicable thereto by giving to the Agent at least three (3) Eurodollar Business
Days' prior irrevocable written notice of continuation in the form of a Notice
of Conversion/Continuation of a Eurodollar Rate Loan and the succeeding Interest
Period(s) of such continued Loan or Loans will commence on the last day of the
Interest Period of the Loan to be continued, provided that no Loan may be
                                             --------                    
continued as a Eurodollar Rate Loan so long as an Event of Default or Potential
Event of default has occurred and is continuing.  Each notice electing to
convert or continue a Loan shall be in the form of a Notice of
Conversion/Continuation and shall specify: (i) the proposed
conversion/continuation date; (ii) the amount of the Loan to be
converted/continued; (iii) the nature of the proposed continuation/conversion;
(iv) in the case of a conversion to, or continuation of, a Eurodollar Rate Loan,
the requested Interest

<PAGE>
 
Period; and (v) the Borrower electing to convert or continue the Loan; and shall
certify that no Event of Default or Potential Event of Default has occurred and
is continuing.  On the date on which such conversion or continuation is being
made each Lender shall take such action as is necessary to effect such
conversion or continuation. In the event that no notice of continuation or
conversion is received by the Agent with respect to outstanding Eurodollar Rate
Loans, upon expiration of the Interest Period(s) applicable thereto, such Loans
shall convert to Base Rate Loans. Subject to the limitations set forth in this
Section and in the definition of Interest Period, all or any part of outstanding
Loans may be converted or continued as provided herein, provided that partial
                                                        ---------            
conversions or continuations with respect to Eurodollar Rate Loans shall be in
an aggregate minimum amount of $1,000,000 and in an integral multiple of
$1,000,000 in excess hereof.

during the period from the date hereof through the Maturity Date that the
Issuing Bank issue Letters of Credit for the account of any of the Borrowers,
                                                                             
provided, however, as follows:

              (i) The aggregate amount available for drawing under all Letters
of Credit at any time outstanding shall not exceed the lesser of Three Million
Dollars ($3,000,000) or the Available Revolving Commitment at such time;

              (ii) Each Letter of Credit issued hereunder shall be in Dollars;

              (iii) Each Letter of Credit shall be governed by the Uniform
Customs and Practices for Documentary Credits as most recently published by the
International Chamber of Commerce (the "UCP") prior to the date of issuance of
                                        ---
such Letter of Credit and the terms of the UCP are hereby incorporated by
reference with respect to each Letter of Credit; and

              (iv) In no event shall the Issuing Bank issue any Letter of Credit
having an expiration date beyond the lesser of one (1) year or the Maturity
Date.

          (b) Request for Issuance:  Payments Under Letters of Credit.  Whenever
              -------------------------------------------------------           
any Borrower requests that the Issuing Bank issue a Letter of Credit, it shall
deliver to the Issuing Bank an executed application for such Letter of Credit in
the form customarily required by the Issuing Bank and the form of the Letter of
Credit requested, together with such other information or materials as the
Issuing Bank may request with respect to such Letter of Credit no later than
1:00 P.M., New York time, at least three (3) Business Days in advance of the
proposed date of issuance. IN DETERMINING WHETHER TO PAY UNDER

                                      20
<PAGE>
 
ANY LETTER OF CREDIT, THE ISSUING BANK SHALL BE RESPONSIBLE ONLY TO DETERMINE
THAT THE DOCUMENTS AND CERTIFICATES REQUIRED TO BE DELIVERED UNDER THAT LETTER
OF CREDIT HAVE BEEN DELIVERED AND THAT THEY COMPLY ON THEIR FACE WITH THE
REQUIREMENTS OF THAT LETTER OF CREDIT.

               (c) Issuance of Letters of Credit.  If the Issuing Bank elects to
                   -----------------------------                                
issue the requested Letter of Credit and upon the satisfaction of all relevant
conditions set forth in Sections 4.1 and 4.3, the Issuing Bank shall issue a
Letter of Credit by delivering the Letter of Credit to the beneficiary, and
shall promptly notify the Agent and the Lenders of the amount and terms thereof.
Any Letter of Credit issued hereunder shall be governed by the terms and
provisions hereof as well as by the terms and provisions of the application
executed in connection therewith pursuant to Section 2.5(b). If the Issuing Bank
declines to issue the requested Letter of Credit it shall promptly so notify the
Borrower requesting such Letter of Credit and such Borrower shall withdraw its
application therefor.

               (d) Participation by Lenders in Letters of Credit.
                   --------------------------------------------- 

                   (i) The Issuing Bank irrevocably agrees to grant and hereby
grants to each Lender, and, to induce the Issuing Bank to issue Letters of
Credit hereunder, each Lender irrevocably severally agrees to accept and
purchase and hereby severally accepts and purchases from the Issuing Bank, on
the terms and conditions hereinafter stated, for such Lender's own account and
risk an undivided interest equal to Lender's ratable share of the Revolving
Commitment in the Issuing Bank's obligations and rights under each Letter of
Credit issued hereunder by the Issuing Bank and each amount paid by the Issuing
Bank thereunder. Each Lender unconditionally and irrevocably severally agree
with the Issuing Bank that, if any amount is paid under any Letter of Credit for
which the Issuing Bank is not reimbursed in full by the Borrowers in accordance
with the terms of this Agreement, such Lender shall pay to the Agent, for the
account of the Issuing Bank, upon demand at the Agent's address for notices, an
amount equal to such Lender's pro rata share of such payment, or any part
thereof, which is not so reimbursed; such amount shall be due on the Business
Day upon which such demand shall be given, if such demand is given on or before
2:00 p.m., New York City time, on such day and, if such demand shall be given
later than such time, such amount shall be due on the next succeeding Business
Day. The Agent shall promptly pay over to the Issuing Bank all amounts so
received by it.

                  (ii) If any amount required to be paid by any Lender to the
Issuing Bank in respect of any unreimbursed portion of any payment made by the
Issuing Bank under any Letter of Credit is paid to the Agent for the account of
the Issuing Bank within three Business Days after the date such payment is due,
such Lender shall pay to the Issuing Bank on demand an

                                      21
<PAGE>
 
amount equal to the product of (A) such amount, times (B) the Federal Funds Rate
during the period from and including the date such payment is required to the
date on which such payment is immediately available to the Issuing Bank, times
(C) a fraction the numerator of which is the number of days that elapsed during
such period and the denominator of which is 360.  If any such amount required to
be paid by any Lender is not in fact made available to the Agent for the account
of the Issuing Bank after the date such payment is due, the Issuing Bank shall
be entitled to recover from such Lender, on demand, such amount with interest
thereon calculated from such due date at the rate per annum then applicable to
Base Rate Loans hereunder.  A certificate of the Issuing Bank submitted to any
Lender with respect to any amounts owing under this section shall be conclusive
in the absence of manifest error.

                  (iii) Whenever, at any time after the Issuing Bank has made
payment under any Letter of Credit and has received from any Lender its pro rata
share of such payment in accordance with this section, the Issuing Bank receives
any payment relate to the Letter of Credit (whether directly from any Borrower
or otherwise), or any payment on interest on account thereof, the Issuing Bank
will pay to the Agent for distribution to such Lender its pro rata share
thereof; provided, however, that in the event that any such payment received by
         --------  -------
the Issuing Bank shall be required to be returned by the Issuing Bank, such
Lender shall return to the Issuing Bank the portion thereof previously
distributed by the Issuing Bank to it.

          (e) Reimbursement of Amounts Drawn Under Letter of Credit.  The
              -----------------------------------------------------      
Issuing Bank shall notify the Borrowers and the Agent of a request for a drawing
under a Letter of Credit promptly after receipt thereof by the Issuing Bank;
                                                                            
provided, however, that the failure to so notify the Borrowers will not relieve
- --------  -------                                                              
the Borrowers from any obligation to reimburse the Issuing Bank hereunder, and
the Borrower for whose account the Letter of Credit was issued shall reimburse
the Issuing Bank for sum amount in immediately available funds prior to 3:00
P.M., New York time, on the date of the drawing.  In the event that the
applicable Borrower shall fail to so reimburse the Issuing Bank, the Issuing
Bank shall promptly notify the Agent who shall promptly notify each Lender.  The
Agent shall pay to the Issuing Bank the amount of the unpaid Letter of Credit
and, thereafter, the Borrower for whose account the Letter of Credit was issued
and the Lenders shall be obligated to reimburse the Agent in respect of such
Letter of Credit prior to 3;00 P.M., New York time, on the date of any such
notice, each Lender shall make a payment under its participation in such Letter
of Credit (which, except as provided in Section 2.5(f)(iii), shall constitute a
Revolving Loan to the Borrower for whose account the Letter of Credit was
issued) in an amount equal to that Lender's ratable share of the unreimbursed
amount of such drawing, by depositing immediately available funds in such amount
in the account of the Agent set forth on the signature pages hereof.  The Agent
shall

                                      22
<PAGE>
 
promptly pay to the Issuing Bank the proceeds of such Revolving Loans, which
shall be used by the Issuing Bank to repay the unreimbursed amount.  Such
Revolving Loans shall be evidenced by the Revolving Notes and shall initially be
Base Rate Loans.  The obligation of each Lender to reimburse the Issuing Bank is
absolute and unconditional and shall not be affected by the occurrence of an
Event of Default or any other occurrence or event.  Any such reimbursement shall
not relieve or otherwise impair the obligation of the Borrower for whose account
the Letter of Credit was issued to reimburse the Issuing Bank for the amount of
any payment made by the Issuing Bank under such Letter of Credit as set forth
herein.  If any Lender fails to make available to the Agent the amount of such
Lender's participation in such Letter of Credit as provided above, the Issuing
Bank shall be entitled to recover such amount on demand from such Lender
together with interest thereon, for each day from the date of notice to such
Lender to the date such amount is paid to the Issuing Bank at a rate which is at
all times equal to three percent (3%) per annum in excess of the Base Rate in
effect from time to time; provided that if the failure to pay is solely the
result of an administrative error (which determination shall be made by the
Agent in its sole discretion) or is solely the result of the Lender receiving
notice too late in the day to make payment to the Agent on that day, then the
interest rate for the first day of such delay shall be the Federal Funds Rate.

          (f) Compensation.  The Borrowers agree to pay the following amount to
              ------------                                                     
the Agent for the account of the Issuing Bank with respect to Letters of Credit:

              (i) with respect to each Letter of Credit, payable on the date of
issuance of such Letter of Credit and on the date of any extension or amendment
to such Letter of Credit, a nonrefundable Letter of Credit fee for the account
of the Issuing Bank equal to one-quarter of one percent (1/4 of 1%) per annum of
the stated amount of such Letter of Credit;

              (ii) with respect to each Letter of Credit, a Letter of Credit fee
for the ratable benefit of the Lenders at the rate of one percent (1%) per annum
on the stated amount of the letter of Credit for the period from and including
the date of issuance of the Letter of Credit to and including the date such
Letter of Credit is drawn in full, expires or is terminated, payable quarterly
in arrears on the last Business Day of each March, June, September and 
December;

              (iii) with respect to drawings made under any Letter of Credit, to
the extent a Revolving Loan is not made to reimburse the Issuing Bank for each
such drawing, interest, payable on demand, on the amount paid by the Issuing
Bank in respect of each such drawing from the date of the drawing through the
date such amount is reimbursed by the Borrower for whose account the Letter of
Credit was issued at a rate which is at all

                                      23
<PAGE>
 
times equal to three percent (3%) per annum in excess of the Base Rate in effect
from time to time; and

              (iv) with respect to the amendment or transfer of each Letter of
Credit and each drawing made thereunder documentary and processing charges for
the account of the Issuing Bank in accordance with the Issuing Bank's standard
schedule for such charges in effect at the time of amendment, transfer or
drawing, as the case may be, or other agreed upon rate.

          (g) Obligations Absolute.  The obligation of the Lenders under Section
              --------------------                                              
2.5(e) shall be unconditional and irrevocable and shall be paid strictly in
accordance with the terms of this Agreement under all circumstances including
the following circumstances:

              (i) any lack of validity or enforceability of any Letter of
Credit;

              (ii) the existence of any claim, set-off, defense or other right
which any Borrower may have at any time against the beneficiary or any
transferee of the Letter of Credit (or any Persons for whom any such transferee
may be acting), the Issuing Bank, the Agent or any other Person, whether in
connection with this Agreement, the transactions contemplated herein or any
unrelated transaction (including any underlying transaction between any Borrower
and the beneficiary for which the Letter of Credit was procured);

               (iii) any draft, certificate or any other document presented
under any Letter of Credit proving to be forged, fraudulent, invalid or
insufficient in any respect or any statement therein being untrue or inaccurate
in any respect; or

               (iv) payment against any draft, document or other demand for
payment that does not comply with the terns of the Letter of Credit, provided
that such payment does not constitute gross negligence or willful misconduct on
the part of the Issuing Bank as determined by a final judgment of a court of
competent jurisdiction; or

               (v) any other circumstance or happening whatsoever, whether or
not similar to any of the foregoing.

          (h) Payments Avoided.  If any payment received on account of any
              ----------------                                            
reimbursement obligation in respect of a Letter of Credit and distributed to a
Lender as a participant under this Section 2.5 is hereafter set aside, avoided
or recovered from the Issuing Bank in connection with any receivership,
liquidation, reorganization or bankruptcy proceeding relating to any Borrower,
each Lender that received a distribution in respect of such payment shall, upon
demand by the Agent, pay to the Issuing Bank the amount of such distribution
received by such Lender.

          (i) Issuing Bank. The Designated Issuer, to the extent that it issues
              ------------                                                     
Letters of Credit hereunder, shall be fully protected for its actions hereunder
and have all of the benefits and immunities provided to a Lender hereunder.


                                  ARTICLE III

                    GENERAL PROVISIONS CONCERNING THE LOANS

         3.1    Use of Proceeds. The proceeds of the Loans hereunder shall be
                ---------------                                              
used by the Borrowers for general corporate purposes

         3.2    Post Maturity Interest. Notwithstanding anything to the contrary
                ----------------------                                          
contained in Section 2.3, if all or a portion of the principal amount of any of
the Loans made hereunder or any interest accrued thereon shall not be paid when
due (whether at the stated maturity, by acceleration or otherwise), any such
overdue amount shall bear interest at a rate per annum which is equal to the
greater of (a) two percent (2%) above the highest rate which would otherwise be
applicable pursuant to Section 2.3 and (b) three percent (3%) above the Base
Rate, from the date of such nonpayment until paid in full (after as well as
before judgment), payable on demand. In addition, such Loan, if a Eurodollar
Rate Loan, shall be converted to a Base Rate Loan at the end of the then current
Interest Period therefor.

         3.3    Computation of Interest.
                ----------------------- 

                (a) Calculations. Interest in respect of the Base Rate Loans and
                    ------------
all fees payable by the Borrowers hereunder shall be calculated on the basis of
a 365 or 366 day year, as the case may be, for the actual days elapsed. Interest
in respect of the Eurodollar Rate Loans shall be calculated on the basis of a
360 day year for the actual days elapsed. Interest payable pursuant to Section
2.5 shall be calculated on the basis of a 365 or 366, as the case may be, day
year for the actual days elapsed. Any change in the interest rate on a Base Rate
Loan resulting from a change in the Base Rate shall become effective as of the
opening of business on the day on which such change in the Base Rate shall
become effective. Any change in the interest rate as a result of a change in the
Debt/Consolidated EBITDA Ratio shall be effective for each Loan on the first day
of each Pricing Period. In computing interest on any Loan, the date of the
making of the Loan shall be included and the date of payment shall be excluded;
provided that if a Loan is repaid on the same day on which it is made, one day's
- --------                                                                        
interest shall be paid on that Loan.

                (b) Determination by Agent. Each determination of an interest
                    ----------------------
rate or fee by the Agent pursuant to any provision of this Agreement shall be
conclusive and binding on the Borrowers in the absence of manifest error.

                                      25
<PAGE>
 
         3.4  Payments.  The Borrowers shall make each payment of principal,
              --------                                                      
interest and fees hereunder and under the Notes, without set-off or
counterclaim, not later than 3:00 P.M., New York time, on the day when due in
lawful money of the United States of America to the Agent at the office of the
Agent designated from time to time in immediately available funds; funds
received by the Agent after that time shall be deemed to have been paid by the
Borrowers on the next succeeding Business Day.  Each Borrower hereby authorizes
the Agent to charge its accounts with the Agent in order to cause timely payment
to be made to the Agent of all principal, interest, fees and expenses due
hereunder (subject to sufficient funds being available in its accounts for that
purpose). The Agent shall notify the Borrowers one (1) Business Day prior to the
date of any charge under this Section 3.4; provided, however, that the failure
                                           --------  -------                  
to so notify the Borrowers will not affect the Agent's right to charge such
accounts. The Agent shall promptly pay to each Lender its pro rata share of each
payment received by the Agent.  All prepayments shall be applied to payment of
accrued interest on the principal amount prepaid before application to
principal.  Any mandatory prepayment shall be applied first to Base Rate Loans
to the full extent thereof before application to Eurodollar Rate Loans.

         3.5    Payment on Non-Business Days.  Whenever any payment to be made
                ----------------------------                                  
hereunder or under the Notes shall be stated to be due on a day which is not a
Business Day, such payment may be made on the next succeeding Business Day and,
with respect to payments of principal, interest thereon shall be payable at the
then applicable rate during such extension

         3.6    Reduced Return. If any Lender or the Issuing Bank shall have
                --------------                                              
determined that any law, regulation, rule or regulatory requirement applicable
to financial institutions generally regarding capital adequacy ("Requirement"),
                                                                 -----------   
or any change therein, or any change in the interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by any Lender
or the Issuing Bank with any request or directive regarding capital adequacy
(applicable to financial institutions generally whether or not having the force
of law) of any such authority, central bank or comparable agent, has or would
have the effect of reducing the rate of return on such Lender's or the Issuing
Bank's capital as a consequence of its Commitment and obligations hereunder, the
Letters of Credit issued hereunder or its obligation to purchase a participation
in the Letters of Credit to a level below that which would have been achieved
but for such Requirement, change or compliance (taking into consideration such
Lender's or the Issuance Bank's, as the case may be, polices with respect to
capital adequacy) by an amount deemed by such Lender or the Issuing Bank, as the
case may be, to be material (which amount shall be determined by such Lender's
or the Issuing Bank's, as the case may be, reasonable allocation of the

                                      26
<PAGE>
 
aggregate of such reductions resulting from such events) then from time to time,
within five (5) Business Days after demand by such Lender or the Issuing Bank,
as the case may be, the Borrowers shall pay to that Lender or the Issuing Bank,
as the case may be, such additional amount or amounts as will compensate that
Lender or the Issuing Bank, as the case may be, for such reduction.

         3.7    Indemnities.
                ----------- 

                (a) General. Whether or not the transactions contemplated hereby
                    -------
shall be consummated, the Borrowers agree to indemnify, pay and hold the Agent,
the Issuing Bank and each Lender, and the shareholders, officers, directors,
employees and agents of the Agent, the Issuing Bank and each Lender (each, an
"Indemnified Person"), harmless from and against any and all claims,
 ------------------
liabilities, losses, damages, costs and expenses (whether or not any of the
foregoing Persons is a party to any ligation), including reasonable attorneys'
fees and costs (including the reasonable estimate of the allocated cost of in-
house legal counsel and staff) and including costs of investigation, document
production, attendance at a deposition, or other discovery, with respect to or
arising out of any proposed acquisition by BEI or any of its Subsidiaries of any
Person or any securities (including a self-tender), this Agreement or any use of
proceeds hereunder, the issuance of any Letter of Credit or the failure by the
Issuing Bank to honor a drawing under a Letter of Credit as a result of any act
or omission of any government or governmental authority, or any claim, demand,
action or cause of action being asserted against BEI or any of its Subsidiaries,
whether or not any Indemnified Person is a party thereto (collectively, the
"Indemnified Liabilities"), except to the extent such Indemnified Liabilities
- ------------------------                                                     
result from the gross negligence or willful misconduct of any such Indemnified
Person. If any claim is made, or any action, suit or proceeding is brought,
against any Indemnified Person, the Indemnified Person shall notify the
Borrowers of such claim or of the commencement of such action, suit or
proceeding, and the Borrowers at their option may, or at the request of the
Indemnified Person will, control and direct the defense of such action, suit or
proceeding, employing counsel selected by the Borrowers and reasonably
satisfactory to the Indemnified Person, and pay the fees and expenses of such
counsel; provided, however, that any Indemnified Person may at its own expense
         --------  -------                                                    
retain separate counsel to participate in such defense.  To the extent that the
undertaking to indemnify, pay and hold harmless set forth in his Section 3.7 may
be unenforceable because it is violative of any law or public policy, the
Borrowers shall contribute the maximum portion which they are permitted to pay
and satisfy under applicable law, to the payment and satisfaction of all
Indemnified Liabilities incurred by any Indemnified Person.

         (b) Funding Losses.  The Borrowers agree to indemnify each Lender and
             --------------                                                   
to hold each Lender harmless from any loss or

                                      27
<PAGE>
 
expense, including any such loss or expense arising from interest or fees
payable by such Lender to Lenders of funds obtained by it in order to maintain
its Eurodollar Rate Loans hereunder, which such Lender may sustain or incur as a
consequence of (i) default by any Borrower in payment of the principal amount of
or interest on the Eurodollar Rate Loans of such Lender, (ii) default by any
Borrower in making a conversion or continuation after such Borrower has given a
notice thereof (other than pursuant to Section 3.13), (iii) default by any
Borrower in making any prepayment after such Borrower has given a notice of
prepayment, or (iv) any Borrower making any payment of a Eurodollar Rate Loan on
a day other than the last day of the Interest Period for such Loan (other than
pursuant to Section 3.13).  For purposes of this Section 3.7, it shall be
assumed that the affected Lender had funded or would have funded 100%, as the
case may be, of each Eurodollar Rate Loan in the inter bank Eurodollar market
for a corresponding amount and term. In the event any Lender makes a claim for
payment under clause (iv) of this Section 3.7(b), the Borrowers shall be
credited with a reinvestment rate equal to the Eurodollar Reinvestment Rate.
Each Lender making a claim for payment under this Section 3.7(b) shall submit to
the Agent, who shall promptly transmit it to the Borrowers, an invoice for the
amount claimed to be owed by the Borrowers, showing in reasonable detail the
calculations necessary to determine the amount.  The determination of such
amount by such Lender shall be presumed correct in the absence of manifest
error.

         3.8    Funding Sources.  Nothing in this Agreement shall be deemed to
                ---------------                                               
obligate any Lender to obtain the funds for any Loan in any particular place or
manner or to constitute a representation by any Lender that it has obtained or
will obtain the funds for any Loan in any particular place or manner.

         3.9    Taxes.
                ----- 

                (a) Payments. Any and all payments by the Borrowers hereunder
                    --------
shall be made free and clear of and without deduction for any and all taxes,
levies, imposts, deductions, charges or withholdings, and all liabilities with
respect thereto, arising under any law, rule or regulation of the United States
or any state or political subdivision hereof, excluding, in the case of each
                                              ---------
Lender, the Agent, each assignee, each participant and the Issuing Bank, taxes
imposed on its net income, and franchise taxes imposed on it, by the
jurisdiction under the laws of which such Lender, Agent, assignee, participant
or Issuing Bank (as the case may be) is organized or any political subdivision
thereof and, in the case of each Lender, the Agent, each assignee, each
participant or the Issuing Bank, taxes imposed on its net income, and franchise
taxes imposed on it, by the jurisdiction of the office or branch in which such
Lender, Agent, assignee, participant or Issuing Bank books the Loans or the
Letters of Credit or in which it is deemed to be doing business or any political
subdivision thereof (all such non-excluded taxes, levies, imposts, deductions,
charges,

                                      28
<PAGE>
 
withholdings and liabilities being hereinafter referred to as "Taxes"). If the
                                                               -----          
Borrowers shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder to any Lender, the Agent, any assignee, any participant or
the Issuing Bank, (i) the sum payable shall be increased as may be necessary so
that after making all required deductions (including deductions applicable to
additional sums payable under this Section 3.9) such Lender, Agent, assignee,
participant or Issuing Bank, as the case may be, receives an amount equal to the
sum it would have received had no such deductions been made, (ii) the Borrowers
shall make such deductions and (iii) the Borrowers shall pay the full amount
deducted to the relevant taxation authority or other authority in accordance
with applicable law; provided that the Borrowers shall not be required pursuant
to clause (i) above to increase the sum payable to any Lender, Agent, assignee,
participant or Issuing Bank organized under the laws of a jurisdiction outside
of the United States if such Lender, Agent, assignee, participant or Issuing
Bank, as the case may be, shall have failed to provide the forms referred to in
Section 3.9(e).

          (b) Other Taxes.  In addition, the Borrowers agree to pay any present
              -----------                                                      
or future stamp or documentary taxes or any other taxes or property taxes,
charges or similar levies arising under any laws, rule or regulation of the
United States or any state or political subdivision hereof which arise from any
payment made hereunder or from the execution, delivery or registration of, or
otherwise with respect to, this Agreement, other than taxes, levies, impose,
deductions, charges or withholdings excluded under Section 3.4 (hereinafter
referred to as "Other Taxes").
                -----------   

          (c) Indemnity.  The Borrowers will indemnify each Lender, the Agent,
              ---------                                                       
each assignee, each participant and the Issuing Bank for the full amount of
Taxes or Other Taxes (including any Taxes or Other Taxes unposed by any
jurisdiction on amounts payable under this Section 3.9), paid by such Lender,
Agent, assignee, participant or Issuing Bank (as the case may be) and any
liability (including penalties, interest and expenses) arising therefrom or with
respect hereto, whether or not such Taxes or Other Taxes were correctly or
legally asserted.  Each Lender, the Agent, each assignee, each participant and
the Issuing Bank, as the case may be, shall notify the Agent, who shall promptly
notify the Borrowers, of the imposition of any such Taxes or Other Taxes within
a reasonable period of time prior to the required payment date of any such Taxes
or Other Taxes: provided, however that the failure to so notify the Borrowers
                --------  -------                                            
will not relieve the Borrowers from any liability hereunder. If the Borrowers
and the affected Lender, Agent, assignee, participant or Issuing Bank, as the
case may be, determining in good faith that the Taxes or Other Taxes are not
correctly or legally asserted, upon Borrowers written request such affected
party agrees to use reasonable efforts to contest the imposition of such Taxes
or Other Taxes, and, in the event of

                                      29
<PAGE>
 
any such contest, the Borrowers shall indemnify, pay and hold the affected party
harmless from and against any and all claims, liabilities, losses, damages,
costs and expenses, including attorneys' fees and costs, incurred by the
affected party in connection with or arising out of such contest within five (5)
Business Days of receipt by any Borrower of a statement from the affected party
setting forth a calculation of the unpaid losses, damages, costs or expenses
incurred to the date of such statement; provided, however, that no affected
                                        --------  -------                  
party shall be required under this Section 3.9(c) to initiate any action or
proceeding before any court or administrative agency. If any Lender, the Agent,
any assignee, any participant or the Issuing Bank makes a claim for payment
under this Section 3.9(c), it shall submit to the Agent, who shall promptly
transmit it to the Borrowers, an invoice for the amount claimed to be owed by
the Borrowers, showing in reasonable detail the calculations necessary to
determine the amount. The determination of such amount by such Lender, Agent,
assignee, participant or Issuing Bank (as the case may be) shall be presumed
correct in the absence of manifest error. This indemnification shall be made
within thirty (30) days from the date such Lender, Agent, assignee, participant
or Issuing Bank (as the case may be) makes written demand therefor. Each Lender,
the Agent, each assignee, each participant and the Issuing Bank agrees to
reimburse the Borrowers for amounts paid by the Borrowers pursuant to this
Section 3.9 to the extent that such Lender, Agent, assignee, participant or
Issuing Bank actually recovers all or any portion of such amounts from the
applicable taxing authority which recovery is specifically designated by such
taxing authority as being applicable to such amounts.

         (d) Evidence of Payment.  Within sixty (60) days after the date of any
             -------------------                                               
payment of Taxes, the Borrowers will furnish to the Agent, at its address
referred to in Section 10.2, the original or a certified copy of a receipt
evidencing payment thereof or other evidence of the payment hereof satisfactory
to the Agent.

         (e) IRS Forms.  Prior to the date of the initial Borrowing (and from
             ---------                                                       
time to time hereafter if requested by the Borrowers or the Agent) each Lender,
Agent, assignee, participant and Issuing Bank organized under the laws of a
jurisdiction outside the United States shall provide the Agent and the Borrowers
with the forms prescribed by the Internal Revenue Service of the United States
certifying as to the status of such Lender, Agent, assignee, participant or
Issuing Bank for purposes of determining exemption from United States
withholding taxes with respect to all payments to be made to such Lender, Agent,
assignee, participant or Issuing Bank hereunder or other documents satisfactory
to the Borrowers and the Agent indicating that all payments to be made to such
Lender, Agent, assignee, participant or Issuing Bank hereunder are subject to
such taxes at a rate reduced by an applicable tax treaty. Unless the Borrowers
and the Agent have received forms or other documents

                                      30
<PAGE>
 
satisfactory to them indicating that payments hereunder are not subject to
United States withholding tax, the Borrowers or the Agent shall withhold taxes
from such payments at the applicable statutory rate or such lower rate as
provided in an applicable tax treaty in the case of payments to or for any
Lender, assignee, participant or Issuing Bank organized under the laws of a
jurisdiction outside the United States.

         3.10   Sharing of Payments Etc.  If any Lender shall obtain any payment
                -----------------------                                         
(whether voluntary, involuntary, through the exercise of any right of set-off,
or otherwise) on account of the Loans owing to it in excess of its ratable share
of payments on account of the Loans obtained by all the Lenders, then such
Lender shall forthwith purchase from the other Lenders such participations in
the Loans owing to them as shall be necessary to cause such purchasing Lender to
share the excess payment ratably with each of them; provided, however, that if
                                                    --------  -------         
all or any portion of such excess payment is thereafter recovered from such
purchasing Lender, such purchase from each Lender shall be rescinded and such
Lender shall repay to the purchasing Lender the purchase price to the extent of
such recovery together with an amount equal to such Lender's ratable share
(according to the proportion of (i) the amount of such Lender's required
repayment to (ii) the total amount so recovered from the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect
of the total amount so recovered. The Borrowers agree at any Lender so
purchasing a participation from another Lender pursuant to this Section 3.10 or
any other provision of this Agreement may, to the fullest extent permitted by
law, exercise all of its rights of payment (including the right to set-off) with
respect to such participation as fully as if such Lender were the direct
creditor of the Borrowers in the amount of such participation.

         3.11   Inability to Determine Interest Rate.  In the event that the
                ------------------------------------                        
Agent or any Lender shall have determined (which determination shall be
conclusive and binding upon the Borrowers) that by reason of circumstances
affecting the inter bank Eurodollar market, adequate and reasonable means do not
exist for ascertaining the Eurodollar Rate applicable pursuant to Section 2.3
for any Interest Period with respect to a Eurodollar Rate Loan that will result
from a requested Eurodollar Rate Loan or that such rate of interest does not
adequately cover the cost of funding such Loan, and the result of any of the
foregoing is to increase the cost to any Lender or the Issuing Bank of making,
receiving or maintaining its Revolving Commitment or Eurodollar Rate Loans or of
issuing, renewing or maintaining the Letters of Credit or purchasing a
participation therein, or to reduce any amount receivable thereunder (which
increase or reduction shall be determined by such Lender's or the Issuing
Bank's, as the case may be, reasonable allocation of the aggregate of such cost
increases or reduced amounts receivable resulting from such events), then, in
any such case, the Borrowers shall pay to such Lender or the Issuing Bank, as
the case may be, within three (3)

                                      31
<PAGE>
 
Business Days of its demand, any additional amounts necessary to compensate such
Lender or the Issuing Bank, as the case may be, for such additional cost or
reduced amount receivable as determined by such Lender or the Issuing Bank, as
the case may be, with respect to this Agreement if any Lender or the Issuing
Bank becomes entitled to claim any additional amounts pursuant to this Section
3.12, it shall notify the Borrowers of the event by reason of which it has
become so entitled. A statement incorporating the calculation as to any
additional amounts payable pursuant to the foregoing sentence submitted by the
affected Lender or the Issuing Bank, as the case may be, to the Borrowers shall
be conclusive in the absence of manifest error.

         3.12   Illegality.  Notwithstanding any other provisions herein, if any
                ----------                                                      
law, regulation, treaty or directive or any change rein or in the interpretation
or application thereof shall make it unlawful, impossible or impracticable for
any Lender to make or maintain Eurodollar Rate Loans as contemplated by this
Agreement, (a) the commitment of such Lender hereunder to make Eurodollar Rate
Loans or convert Base Rate Loans to Eurodollar Rate Loans shall forthwith be
cancelled and (b) such Lender's Loans then outstanding as Eurodollar Rate Loans,
if any, shall be converted automatically to Base Rate Loans on the next
succeeding Interest Payment Date or within such earlier period as allowed by
law. The Borrowers hereby agree to pay any Lender, within three (3) Business
Days of its demand, any additional amounts necessary to compensate such Lender
for any costs (excluding loss of anticipated profits) incurred by such Lender in
making any conversion in accordance with this Section 3.13, including any
interest or fees payable by such Lender to lenders of funds obtained by it in
order to make or maintain its Eurodollar Rate Loans hereunder. Each Lender
making a claim for payment under this Section 3.13 shall submit to the Agent,
who shall promptly transmit it to the Borrowers, an invoice for the amount
claimed to be owed by the Borrowers, showing in reasonable detail the
calculations necessary to determine the amount.  The determination of such
amount by such Lender shall be presumed correct in the absence of manifest
error.

         3.13   Change of Booking Office.  Any Lender claiming any additional
                ------------------------                                     
amounts payable pursuant to Section 3.9 or 3.12 shall use its reasonable efforts
(consistent with its internal policy and legal and regulatory restrictions) to
change the jurisdiction of the office or branch in which it books the Loans if
the making of such a change would avoid the need for, or reduce the amount of,
any such additional amounts which may thereafter accrue and would not, in the
reasonable judgment of such Lender, be otherwise disadvantageous to such Lender;
                                                                                
provided, however, that such Lender shall not be obligated to use such other
- --------  -------                                                           
office or branch pursuant to this Section 3.14 unless the Borrowers agree to pay
all reasonable expenses incurred by such Lender in using such other office or
branch.

                                      32
<PAGE>
 
         3.14   Right to Replace Lender. If the Borrowers shall, as a result of
                -----------------------                                        
the requirements of Section 3.6 or 3.12, be required to pay any Lender the
additional costs referred to in such Section, the Borrowers shall have the right
to substitute another financial institution satisfactory to the Agent (whose
approval will not be unreasonably withheld) for such Lender which has submitted
an invoice for such additional costs. Any such substitution shall be on terms
and conditions satisfactory to the Agent. Until such time as such substitution
shall be consummated, the Borrowers shall continue to pay any additional costs
invoiced by such Lender and shall continue to pay all other amounts payable to
such Lender hereunder. Upon any such substitution, the Borrowers shall pay or
cause to be paid to the Lender that is being replaced all principal, interest
(to the date of such substitution) and other amounts owing hereunder to such
Lender.

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

guarantee or right of set-off at any time held by the Agent or any Lender for

Reasons for the              
 Distribution............... The Board of Directors of Electronics believes    
                             that the Distribution is in the best interests of 
                             Electronics and its shareholders for various      
                             reasons, including (a) improving Technologies'    
                             and Medical's ability to meet their respective    
                             financing needs by increasing Technologies' debt  
                             capacity and lowering the cost of equity for both 
                             Technologies and Medical, (b) offering incentives 
                             that are more attractive and appropriate for the  
                             recruitment, motivation and retention of          
                             Technologies' and Medical's respective key        
                             employees, (c) creating enhanced acquisition      
                             opportunities using stock of Technologies as      
                             consideration, and (d) permitting Technologies to 
                             pursue the development of its sensors and systems 
                             business without regard to the corporate and      
                             financial objectives and policies of Medical.      

Relationship Between
 Electronics and             
 Technologies After the      
 Distribution............... Immediately following the Distribution, all       
                             outstanding shares of Technologies Common Stock   
                             will be owned by stockholders of Electronics.     
                             Shares of the two companies will trade            
                             independently. Prior to the Distribution, the     
                             Company and Electronics will enter into a         
                             Distribution Agreement, a Technology Transfer and 
                             License Agreement, an Assumption of Liabilities   
                             and Indemnity Agreement, a Trademark Assignment   
                             and Consent Agreement, a Corporate Services       
                             Agreement, an Agreement Regarding Certain         
                             Representations and Covenants and a Tax           
                             Allocation and Indemnity Agreement governing the  
                             relationship between the parties subsequent to    
                             the Distribution. See "The Distribution--         
                             Relationship between Electronics and Technologies 
                             after the Distribution."                           

                                 
Related Transactions........ In connection with the Distribution, and subject 
                             to the noteholders' agreement, Technologies will 
                             assume Electronics' obligations related to the   
                             service and repayment of $22.4 million in Senior 
                             Notes. Management plans to transfer up to $9.0   
                             million in cash from Sensors & Systems to        
                             Electronics which will be funded through a       
                             combination of existing cash balances and        
                             borrowings by Sensors & Systems of up to $9.0    
                             million. The cash transfer will be made to repay 
                             a portion of amounts due from Sensors & Systems  
                             to Electronics resulting from recurring          
                             intercompany transactions. Management estimates  
                             that net intercompany obligations of Electronics 
                             to Sensors & Systems and Defense will be         
                             approximately $4.0 million at the Effective Date.
                             These net obligations will be assumed by         
                             Technologies in connection with the Distribution.
                             Technologies intends to establish a bank line of 
                             credit which would permit borrowings after the   
                             Distribution. See "Related Transactions--        
                             Financing Transactions" and "Financing--Bank     
                             Credit Facilities."                               
 
Management of the Company... Immediately after the Effective Date, all of the
                             executive officers of Technologies are expected
                             to be persons who currently serve as officers of
                             Electronics or Sensors & Systems. All such
                             persons will resign from their positions as
                             executives of Electronics, except Charles
                             Crocker, who will retain his position as Chairman
                             of the
 
                                       vi
<PAGE>
 
                             Board of Directors of Electronics, so that
                             Technologies and Electronics will otherwise have
                             no executive officers in common. See "Executive
                             Officers and Directors of the Company."
 
Post-Distribution Dividend
 Policy..................... Electronics has paid a cash dividend of $.02 per
                             share of Electronics Common Stock each quarter
                             since Electronics' initial public offering in
                             1989. The payment of future dividends, if any, by
                             Electronics or Technologies will be at the
                             discretion of their respective Boards of
                             Directors. See "The Distribution--Other
                             Consequences of the Distribution--Dividend
                             Policies."
 
                                  
Certain Federal Income Tax
 Consequences............... Prior to the Distribution, the Company will      
                             receive an opinion of counsel that, although the 
                             matter is not free from doubt, the Distribution   
                             will qualify as tax free to Electronics and its  
                             Stockholders. Opinions of counsel are not binding
                             on the Internal Revenue Service or the courts.   
                             See "The Distribution--Certain Federal Income Tax
                             Consequences of the Distribution" for a more     
                             detailed description of the opinion of counsel   
                             and federal income tax consequences of the       
                             Distribution.                                     
                             
Certain Provisions of
 Certificate of
 Incorporation and Bylaws;
 Rights Plan................ Certain provisions of Technologies' Certificate
                             of Incorporation and Bylaws, as each will be in
                             effect following the Distribution, may have the
                             effect of making more difficult an acquisition of
                             control of the Company in a transaction not
                             approved by its Board of Directors. See "Certain
                             Anti-takeover Effects of Certain Provisions of
                             the Certificate of Incorporation, Bylaws and
                             State Law." The Certificate of Incorporation
                             would eliminate certain liabilities of
                             Technologies' directors in connection with the
                             performance of their duties. See "Liability and
                             Indemnification of Directors and Officers." The
                             Preferred Share Purchase Rights Plan
                             ("Stockholder Rights Plan") will make more
                             difficult an acquisition of control of the
                             Company in a transaction not approved by its
                             Board of Directors. See "Stockholder Rights

                         SUMMARY FINANCIAL INFORMATION
 
                             BEI TECHNOLOGIES, INC.
 
                       SUMMARY HISTORICAL FINANCIAL DATA
                    (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
  The following summary historical balance sheet data at September 30, 1995 and
September 28, 1996 and statement of operations data for the three years in the
period ended September 28, 1996 have been derived from combined financial
statements of Technologies audited by Ernst & Young LLP, independent auditors,
included elsewhere herein. The following summary historical balance sheet data
at October 3, 1992, October 2, 1993 and October 1, 1994 and statement of
operations data for the two years in the period ended October 2, 1993 have been
derived from unaudited combined financial statements not included in this
Information Statement. The summary statement of financial data at June 28, 1997
and for the nine-month periods ended June 29, 1996 and June 28, 1997 have been
derived from unaudited interim combined financial statements included elsewhere
herein. In the opinion of management, the unaudited interim combined financial
statements include all adjustments, consisting only of normal recurring
adjustments, necessary for a fair presentation of the financial position of the
Company at June 29, 1996 and June 28, 1997, and the results of its operations
for the nine-month periods then ended. The historical combined financial
statements of the Company do not necessarily reflect the results of operations
or financial position that would have resulted had the Company been a separate,
independent company and are not necessarily indicative of the results to be
expected for any other interim period or any future fiscal year. The historical
financial data does not include the effect of anticipated financing
transactions in connection with the Distribution (See "The Distribution--
Related Transactions"). See "Selected Unaudited Pro Forma Financial Data,"
"Selected Historical Financial Data," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Summary Unaudited Pro forma
Financial Data" and "Combined Financial Statements" and accompanying notes
thereto. See also Note 1 of Notes to Combined Financial Statements for
explanation of shares used in pro forma earnings per share calculations.

                   SUMMARY UNAUDITED PRO FORMA FINANCIAL DATA
                (AMOUNTS IN THOUSANDS EXCEPT PER SHARE AMOUNTS)
   
  The following summary unaudited pro forma financial data of the Company give
effect to certain planned financing transactions in connection with the
Distribution as if such transactions had occurred at the beginning of each
period presented for statement of operations data, and as of the balance sheet
date for balance sheet data. The planned financing transactions include
borrowings by Sensors & Systems of up to $9.0 million and the transfer of up to
$9.0 million in cash to Electronics as repayment of a portion of amounts
payable from Sensors & Systems to Electronics. The planned financing
transactions also include the assumption by Technologies of net obligations
payable by Electronics to Sensors & Systems and Defense, estimated to be
approximately $4.0 million at the time of the Distribution. Interest charges on
net amounts payable to Electronics have not been significant.     
 
  The summary unaudited pro forma statement of operations data do not purport
to represent what the Company's results of operations would have been if the
financing transactions had occurred as of such dates or what such results will
be for any future periods. See "Selected Unaudited Pro forma Financial Data,"

                          FORWARD-LOOKING STATEMENTS
 
  This Information Statement may contain forward-looking statements that
involve risks and uncertainties. When used in this Information Statement, the
words "anticipate", "believe", "estimate", "expect" and similar expressions as
they relate to Electronics or the Company or their respective Boards of
Directors or management are intended to identify such forward-looking
statements. The Company's actual results, performance or achievements could
differ materially from the results expressed in, or implied by, these forward-
looking statements. Factors that could cause or contribute to such differences
include those discussed in "The Business," in "Risk Factors," in "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
elsewhere in this Information Statement.
 
                               THE DISTRIBUTION
 
REASONS FOR THE DISTRIBUTION
 
  The Board of Directors of Electronics, after careful study and analysis, has
concluded that it is in the best interests of Electronics and its stockholders
to undertake the Distribution based on its belief that each of its businesses
would enjoy substantially improved performance and access to capital markets
if its business, strategy, organization and employee incentives were tightly
focused on closely associated products and markets. The Board of Directors
believes that the Distribution should be beneficial to each of Electronics'
current businesses, because it will separate businesses with distinct
financial, investment and operating characteristics so that each can adopt
strategies and pursue objectives more appropriate to its specific businesses
than is possible under Electronics' present combined structure and so that
each company can be valued independently of the other. It is much easier for
management, employees and capital markets to focus on and understand the
business goals and objectives of a corporation that focuses on customers with
related needs and that specializes in products that have related engineering,
manufacturing, and marketing characteristics.
 
  The Board of Directors of Electronics believes strategic planning should
begin with a review of the business environment and a company's competitive
position with other industry participants. In that setting, organizational
structure, personnel selection and incentive systems (in particular, stock
options, which provide long-term motivation to employees) can properly be
based on the specific business goals and strategies for the specific industry
in which the company operates. The Board believes it is substantially easier
for employees to relate to, internalize and endorse the business strategy of a
specific industry rather than an aggregation of different industries.
 
  The Board of Directors of Electronics believes that Technologies' growth
will be better facilitated in several ways as a separate public company.
Foremost among the anticipated benefits is the expectation that, as a separate
public company, Technologies will be able to obtain needed financing on more
favorable terms than its businesses now can as a part of Electronics. In
addition, management believes that it will be better able to attract and
motivate existing and new key employees by providing stock-based incentive
compensation tied directly to the results of their efforts as reflected in the
market price of the Technologies Common Stock. The establishment of the
Technologies Common Stock as a separate, publicly-traded equity security
should provide Technologies enhanced acquisition opportunities by using
Technologies Common Stock as consideration.
 
  The Board of Directors of Electronics foresees similar benefits for Medical
if it were a separate company. Financing is expected to be more readily
available from that portion of the equity market that desires to specialize in
emerging medical device companies in contrast with the present condition in
which medical, industrial and defense businesses are all co-mingled inside
Electronics. The ability to attract and to provide incentives to employees who
wish to make a career with a medical products company should also be enhanced,
as will the ability to make acquisitions of medical companies using Medical
stock as currency.
 
  Finally, the Board of Directors of Electronics expects that the Distribution
will enable capital markets to better recognize and evaluate the different
merits of Technologies and Medical as separate public companies,
 
                                       1
<PAGE>
 
enhancing the likelihood that each will achieve appropriate market recognition
of its performance and prospects. Electronics' management believes that the
financial and investment communities do not fully value Electronics, in large
part because Electronics operates businesses in disparate industries. The
Board of Directors of Electronics believes that the separation of Technologies
and Medical would allow potential lenders and equity investors to understand
more clearly the business of each company and will thereby reduce each
company's cost of capital.
 
  For the reasons stated above, the Electronics Board of Directors believes
that the Distribution is in the best interests of Electronics and its
stockholders.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE DISTRIBUTION
   
  As a condition to the completion of the Distribution, Electronics and the
Company will receive an opinion from Davis Polk & Wardwell, special tax
counsel to Electronics, to the effect that, although the matter is not free
from doubt, the Distribution will qualify as tax-free to Electronics and its
stockholders under Section 355 of the Internal Revenue Code of 1986, as
amended (the "Code"). The tax opinion will be based upon factual
determinations and upon legal issues as to which there are no regulations,
published rulings or judicial decisions directly on point, and accordingly,
the opinion will be qualified as being not free from doubt. In addition,
opinions of counsel are not binding on the Service or the courts, and the
Service may challenge positions taken based upon this opinion. However, Davis
Polk & Wardwell is of the opinion that, although the matter is not free from
doubt, if the Service were to assert that the Distribution did not qualify as
tax-free, the Service would not prevail in a judicial proceeding in which the
issues and facts were properly presented.     
 
  Assuming that the Distribution qualifies as tax-free for federal income tax
purposes:
 
    (i) An Electronics stockholder will not recognize gain or loss as a
  result of the Distribution.
 
    (ii) An Electronics stockholder will apportion its tax basis for its
  Electronics Common Stock between its Electronics Common Stock and
  Technologies Common Stock received in the Distribution in proportion to the
  relative fair market values of the Electronics Common Stock and
  Technologies Common Stock on the Effective Date.
 
    (iii) An Electronics stockholder's holding period for the Technologies
  Common Stock received in the Distribution will include the period during
  which the stockholder held the Electronics Common Stock with respect to
  which the Distribution was made, provided that the Electronics Common Stock
  is held as a capital asset by the stockholder as of the Effective Date.
 
    (iv) Except to the extent of any excess loss accounts or deferred
  intercompany gains, no gain or loss will be recognized to Electronics as a
  result of the Distribution.
 
  The tax opinion will rely upon, among other things, certain representations
made by Electronics and Technologies to Davis Polk & Wardwell. If it were
subsequently determined that those representations were inaccurate or
incomplete, the conclusion in the tax opinion could not be relied upon.
 
  If the Distribution does not qualify as a tax-free distribution, the fair
market value of the shares of Technologies Common Stock received by the
Electronics stockholders would be taxable as a dividend. In that event, the
tax basis of the shares of Technologies Common Stock held by the Electronics
stockholders after the Distribution would not change and the tax basis of the
shares of Technologies Common Stock would be equal to their fair market value
on the Effective Date. In addition, Electronics would recognize a capital gain
equal to the difference between the fair market value of the shares of
Technologies Common Stock and Electronics' basis in the shares.
 
  Current U.S. Department of Treasury ("Treasury") regulations require each
Electronics stockholder who receives Technologies Common Stock pursuant to the
Distribution to attach to such stockholder's federal income tax return for the
year in which the Distribution occurs a descriptive statement concerning the
Distribution.
 
                                       2
<PAGE>
 
Electronics (or the Company on its behalf) will make available requisite
information to each Electronics stockholder of record as of the Record Date.
 
  ALL STOCKHOLDERS SHOULD CONSULT THEIR OWN TAX ADVISERS REGARDING THE
PARTICULAR FEDERAL, FOREIGN, STATE AND LOCAL TAX CONSEQUENCES OF THE
DISTRIBUTION TO THEM.
 
  For a description of agreements pursuant to which Electronics and the
Company have provided for certain tax sharing and other tax matters, see
"Relationship Between Electronics and Technologies After the Distribution--Tax
Agreement."
 
MANNER OF EFFECTING THE DISTRIBUTION
   
  Electronics will effect the Distribution on the Distribution Date by
delivering approximately 7,115,000 shares of Technologies Common Stock to
ChaseMellon Shareholder Services, L.L.C. as the distribution agent (the
"Distribution Agent"), for distribution to the holders of record of
outstanding shares of Electronics Common Stock on the Record Date. The
Distribution will be made on the basis of one share of Technologies Common
Stock for every one share of Electronics Common Stock outstanding on the
Record Date. All such shares will be fully paid, nonassessable and free of
preemptive rights. Upon completion of the Distribution, there will be
approximately 7,115,000 shares of Technologies Common Stock outstanding. No
portion of the shares that will be issued and outstanding upon completion of
the Distribution is being, or has been proposed to be, publicly offered by
Technologies. All of these shares will be immediately eligible for sale in the
public market without restriction under the Securities Act of 1933, as amended
(the "Securities Act"), except that any shares owned by affiliates of
Technologies may generally only be sold in compliance with the applicable
provisions of Rule 144 promulgated by the SEC under the Securities Act. See
"Description of Capital Stock."     
 
  The Distribution Agent will mail, beginning on or about October 10, 1997,
certificates representing Technologies Common Stock to the Electronics
stockholders. Electronics stockholders will not be required to pay for shares
of Technologies Common Stock received in the Distribution or to surrender or
exchange shares of Electronics Common Stock to receive shares of Technologies
Common Stock. No vote of Electronics stockholders is required or sought in
connection with the Distribution, and Electronics stockholders have no
appraisal rights in connection with the Distribution.
       
OPINION OF FINANCIAL ADVISOR
   
  Electronics retained SBC Warburg Dillon Read, Inc., formerly Dillon, Read &
Co. Inc. ("Dillon Read"), to act as Electronics' financial advisor in
connection with the Distribution and related matters based upon Dillon Read's
experience and expertise. Dillon Read rendered a written opinion to the Board
of Directors of Electronics that, as of the date of its opinion and subject to
the considerations set forth in such opinion, the proposed Distribution is
fair from a financial point of view to the holders of shares of Electronics
Common Stock.     
 
  THE FULL TEXT OF DILLON READ'S WRITTEN OPINION DATED SEPTEMBER 11, 1997,
WHICH SETS FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON
THE REVIEW UNDERTAKEN, IS ATTACHED AS ANNEX A TO THIS INFORMATION STATEMENT
AND IS INCORPORATED HEREIN BY REFERENCE. STOCKHOLDERS ARE URGED TO, AND
SHOULD, READ THE DILLON READ OPINION CAREFULLY AND IN ITS ENTIRETY. THE DILLON
READ OPINION IS DIRECTED TO THE BOARD OF DIRECTORS OF ELECTRONICS AND CONCERNS
THE FAIRNESS OF THE PROPOSED DISTRIBUTION FROM A FINANCIAL POINT OF VIEW TO
THE HOLDERS OF SHARES OF ELECTRONICS COMMON STOCK, AND IT DOES NOT ADDRESS ANY
OTHER ASPECT OF THE DISTRIBUTION. DILLON READ'S OPINION DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY CURRENT OR PROSPECTIVE STOCKHOLDER OF EITHER ELECTRONICS
OR TECHNOLOGIES AS TO ANY ACTION OR INVESTMENT DECISION SUCH PARTY OR PERSON
MAY TAKE. THE SUMMARY OF THE DILLON READ OPINION SET FORTH IN THIS INFORMATION
STATEMENT IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH
OPINION.
 
                                       3
<PAGE>
 
  In arriving at its opinion, Dillon Read (i) conducted discussions with
members of the senior management of Electronics and with the senior management
of Technologies with regard to the business and prospects of each company;
(ii) analyzed certain historical business and financial information related to
Electronics and Technologies prepared by Electronics management; (iii)
reviewed certain financial projections for Electronics and Technologies
prepared by Electronics management; (iv) reviewed public information relating
to Electronics, including Electronics' Annual Report and Form 10-K for the
five fiscal years ended September 28, 1996; (v) reviewed public information
with respect to certain other companies engaged in businesses which Dillon
Read believed to be generally comparable to certain of the businesses
conducted by Electronics and Technologies; (vi) reviewed the Information
Statement; and (vii) conducted such other studies, analyses and investigations
and reviewed such other economic and market data as Dillon Read deemed
necessary or appropriate.
 
  In connection with the delivery of its opinion, Dillon Read discussed with
the Board, among other things, Dillon Read's analysis of the possible post-
Distribution market values of Electronics Common Stock and Technologies Common
Stock. The analysis was based on a range of price/earnings multiples of 1997
and 1998 calendar year earnings estimates for the Company and equity market
capitalizations less cash for Electronics. The price/earnings multiples and
equity market capitalizations less cash used in the analysis were compared to
the price/earnings multiples and equity market capitalizations less cash for
certain publicly-traded companies which Dillon Read deemed generally
comparable to the Company and Electronics, respectively. The analysis
generally indicated that, on a post-Distribution basis, based on the earnings
estimates and price/earnings multiples and equity market capitalizations less
cash that were considered most appropriate, the combined implied market value
of one share of Electronics Common Stock and one share of Technologies Common
Stock would exceed the closing market price per share of Electronics Common
Stock on the day prior to the Board's determination to pursue the
Distribution.
   
  In addition, Dillon Read analyzed the financial effects of the Distribution,
including (i) the ability to enhance the value of the Company's businesses as
an independent company with a lower cost of new debt and equity financing,
simplified management structure and focused management incentives, (ii) the
ability to reposition Electronics with a greater emphasis on its medical
devices business, (iii) creating enhanced acquisition opportunities using
stock as consideration, (iv) the enhanced focus of Electronics' and the
Company's management teams, and (v) the tax-free nature of this transaction.
Dillon Read also discussed with the Board Dillon Read's view of certain
potential detriments of the Distribution, including potential redistribution
of Technologies Common Stock for a period of time following the Distribution.
    
  In rendering its opinion, Dillon Read with the Board's consent, assumed and
relied upon, without independent verification, the accuracy and completeness
of the information reviewed by Dillon Read for the purposes of its opinion.
With respect to the financial budgets and forecasts, Dillon Read, at the
Board's direction, assumed that they were reasonably prepared on bases
reflecting the best currently available estimates and judgments of the future
financial performance of Electronics and the Company. Dillon Read did not make
any independent valuation or appraisal of the assets or liabilities,
contingent or otherwise, of Electronics or the Company, nor has Dillon Read
been furnished with any such appraisals.
   
  Dillon Read noted that Electronics, as a condition to the Distribution,
expects to receive an opinion from Davis Polk & Wardwell to the effect that,
although the matter is not free from doubt, the Distribution will not be a
taxable transaction to Electronics or to the stockholders of Electronics under
federal income tax laws. In that regard, Dillon Read assumed that such opinion
will be delivered to Electronics.     
 
  Dillon Read's opinion was rendered on the basis of securities markets,
economic and general business and financial conditions prevailing as of the
date of its opinion, and the conditions and prospects, financial and
otherwise, of Electronics and the Company as they were represented to Dillon
Read as of the date of its opinion or as they were reflected in the
information and documents reviewed by Dillon Read. Dillon Read's opinion
assumed that the Distribution will be completed substantially on the basis set
out in the Information Statement.
 
                                       4
<PAGE>
 
  Dillon Read was not asked to, and did not, provide any opinion as to the
valuation or long-term viability of Electronics or the Company as independent
public companies following the Distribution. In rendering its opinion, Dillon
Read did not opine as to the price at which the common stock of Electronics or
the Company will trade after the Distribution is effected.
 
  As financial advisor to Electronics in connection with the Distribution,
Dillon Read has been paid an advisory fee of $100,000 which compensated Dillon
Read for the time and efforts expended in rendering advice in connection with
the Distribution and upon consummation of the Distribution, Dillon Read will
be paid a transaction fee of $400,000. Electronics has agreed to reimburse
Dillon Read for its out-of-pocket expenses incurred in connection with its
services as financial advisor. Electronics has also agreed to indemnify Dillon
Read and its affiliates, their respective directors, officers, agents and
employees and each person, if any, controlling Dillon Read or any of its
affiliates against certain liabilities, including liabilities under the
federal securities laws, and expenses related to Dillon Read's engagement.
 
  Dillon Read was selected by the Electronics' Board to act as Electronics'
financial advisor based upon Dillon Read's qualifications, expertise and
reputation. Dillon Read is a nationally recognized investment banking firm and
is regularly engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings and private
placements.
 
RELATIONSHIP BETWEEN ELECTRONICS AND TECHNOLOGIES AFTER THE DISTRIBUTION
 
  Immediately following the Distribution, all outstanding shares of
Technologies Common Stock will be owned by stockholders of Electronics. Shares
of the two companies will trade independently.
 
  Subsequent to the Distribution, Technologies will operate independently from
Electronics. Electronics and Technologies are not expected to become
competitors because the companies will be engaged in the development and
marketing of different types of products with different applications in
different markets. See "Description of the Business--Competition."
 
  Because Electronics has provided Sensors with treasury, management,
financial and other administrative services in the past, Technologies will
expand its financial, tax and administrative staffs as a result of the
Distribution.
   
  Distribution Agreement. The general terms and conditions of the Distribution
are set forth in the Distribution Agreement to be entered into between
Electronics and Technologies prior to the Distribution. The following is a
summary of the principal provisions of the Distribution Agreement.     
 
  The Distribution Agreement provides for the contribution to Technologies of
the equity interests of the Sensors & Systems business, the Defense Systems
business and miscellaneous other assets that relate to these businesses and
the executive office function which are held by Electronics in exchange for
the Technologies Common Stock. See "The Business--Introduction and Historical
Overview."
 
  The Distribution Agreement also provides for assumption by Technologies of
$22.4 million in Senior Note obligations of Electronics, the renegotiation and
assumption by Technologies of the existing credit agreement between
Electronics and Canadian Imperial Bank of Commerce ("CIBC"), the repayment of
certain intercompany accounts and the assumption by Technologies of
approximately $4.0 million in intercompany obligations due Electronics by
Sensors & Systems and Defense at the time of the Distribution. See "Related
Transactions--Assumption of Note Obligations," and "Financing--Bank Credit
Facilities" below.
 
  The Distribution Agreement provides that Technologies has the right to hire
certain individuals approved by Electronics who are or have been employees of
Electronics. Electronics will have no further responsibility or
 
                                       5
<PAGE>
 
liability with respect to the employment relationship of such employees upon
the effectiveness of the Distribution, other than with respect to the final
settlement of obligations with respect to such employees under existing
Electronics incentive and benefit plans.
 
  The Distribution Agreement provides that in connection with the transfer of
assets and the assumption of liabilities relating to the separation of the
businesses of Technologies and Electronics, Technologies and Electronics shall
execute or cause to be executed various conveyancing and assumption
instruments in such forms as the parties to the Distribution Agreement shall
agree.
 
  Pursuant to the Distribution Agreement, Electronics agrees to obtain all
consents, permits and authorizations necessary to transfer and agrees to
transfer to Technologies any assets associated with Technologies business that
have not been transferred by the Effective Date. In addition, Electronics
agrees to obtain consents, permits and authorizations necessary to permit
Technologies to assume any liabilities associated with Technologies business
that have not been assumed by Technologies by the Effective Date. There are no
material assets or liabilities related to the business of the Company that
will not be transferred to the Company effective on or shortly following the
Effective Date. The Distribution Agreement also provides that expenses
associated with the Distribution will be charged to and paid by Electronics
and allocated to the parties on an equitable basis.
   
  Assumption of Liabilities and Indemnification Agreement. Under the
Assumption of Liabilities and Indemnification Agreement, except as provided in
the Tax Agreement described below, Technologies and Electronics will each be
responsible for all claims and liabilities relating to their respective
businesses, whether or not such claims and liabilities are asserted prior to
the Distribution, and will each indemnify the other against such claims and
liabilities. Electronics will have no continuing financial interest in
Technologies, except that it may remain an obligor or guarantor for certain
existing obligations of Technologies pursuant to the Distribution Agreement.
Technologies has agreed to indemnify Electronics to the extent of any payments
made on those obligations. In connection with the Distribution, Electronics
will attempt to obtain releases from its existing guarantees relating to
certain of Technologies' obligations. To the extent it is unsuccessful,
Electronics will remain liable after the Distribution on such guarantees,
subject to Technologies' indemnification of Electronics.     
 
  Corporate Services Agreement. Electronics and Technologies will make
available to each other for a transition period generally not expected to
exceed the end of calendar year 1998 certain personnel, services and records,
with each party being reimbursed for any costs and expenses incurred in
connection therewith. The Corporate Services Agreement further provides for
Medical's continued use, during such period, of certain centralized staff
services and systems, such as health claims administration, oversight of
compliance with public company reporting requirements, the preparation and
filing of tax returns and the administration of retirement plan asset
investment services, with Technologies being paid on an arm's length basis for
such services.
 
  Tax Agreement. Prior to the Distribution, agreements will also be entered
into that reflect each party's rights and obligations with respect to
deficiencies and refunds of federal, state or other income taxes relating to
the business of Electronics that are attributable to periods ending prior to
or on the Effective Date (the "Tax Agreement"). The Tax Agreement also
expresses each party's intention with respect to certain tax attributes of
Technologies after the Distribution. The Tax Agreement provides that
Electronics shall be responsible for federal, state and local income taxes
relating to the Sensors & Systems and Defense Systems businesses of
Technologies for periods up to and including the Effective Date. The Tax
Agreement provides for payments between the two companies for certain audit
adjustments made after the Distribution that cover pre-Distribution tax
liabilities. Other provisions cover the handling of audits, settlements, stock
options, elections, accounting methods, and return filings in cases where both
companies have an interest in the results of these activities. In addition,
the Tax Agreement requires Electronics and Technologies to cooperate in
preparing those filings that cover overlapping taxable periods that include
the Effective Date.
 
  Pursuant to the Tax Agreement the Company will agree to refrain from
engaging in certain transactions for two years following the Effective Date
unless it shall first provide Electronics with a ruling from the Internal
 
                                       6
<PAGE>
 
Revenue Service or an unqualified opinion of nationally recognized tax counsel
that the transaction will not cause the Distribution to become taxable.
Transactions subject to these restrictions will include, among other things,
the liquidation, merger, or consolidation with another company, the issuance
or redemption of Company Common Stock, the sale, distribution or other
disposition of assets out of the ordinary course of business, and the
discontinuation of certain businesses, except as such transaction relates to
the discontinuation of the Defense business. The Company will generally agree
to indemnify Electronics against any tax liability resulting from the
Company's breach of any covenant or representation contained in the Tax
Agreement with respect to such transactions. In addition, the Company and
Electronics have each agreed that neither party will take any action
inconsistent with the information furnished by it in connection with the
rendering of the legal opinion regarding the tax-free nature of the
Distribution and, until the expiration of the statute of limitations period
applicable to the taxable year in which the Distribution occurs, neither party
will make or change any accounting method, amend any tax return or take any
tax position on any tax return, change the manner in which it conducts its
business, or take (or omit to take) another action that results in any
increased tax liability relating to a pre-Distribution tax period. The Company
and Electronics have each agreed to indemnify the other for liabilities
arising as a result of the breach by the Company or Electronics, as the case
may be, of the Tax Agreement.
 
  Technology Transfer and License Agreement. The Technology Transfer and
License Agreement provides for the assignment of intellectual property and
technology other than trademarks to the party that utilized it prior to the
Distribution. Technologies also grants Electronics an irrevocable, royalty
free, worldwide, nonexclusive license to utilize the intellectual property and
technology assigned to Technologies to produce medical devices if such
intellectual property and technology had been used by Electronics or its
subsidiaries prior to the Distribution.
   
  Trademark Assignment and Consent Agreement. The Trademark Assignment and
Consent Agreement assigns existing trademarks between the parties based upon
usage prior to the Distribution.     
   
  The foregoing summary of certain agreements is qualified in its entirety by
reference to the full text of such agreements, which have been filed as
Exhibits to the Registration Statement of which this Information Statement is
a part.     
 
RELATED TRANSACTIONS
 
  Assumption of Note Obligations. Electronics currently has $22.4 million of
outstanding Series A and Series B Senior Notes. The Series A Notes call for
principal repayments of $3.4 million on October 1 of each year through the
year 2000. The Series B Notes call for principal repayments of $2.2 million on
November 15 through the year 2000. The interest on the Notes was 6.73%. In
connection with the Distribution, Technologies will assume the Senior Note
obligations subject to the noteholders' agreement, at a revised rate of
interest of 7.23% and the modification of certain financial covenants to be
more favorable to the Company. The repayment terms on the Notes will not
change as a result of the assumption. See Note 5 of Notes to Combined
Financial Statements.
 
  Financing Transactions. Prior to the Distribution, Sensors & Systems plans
to transfer up to $9.0 million in cash to Electronics to repay a portion of
amounts due from Sensors & Systems to Electronics from recurring intercompany
transactions. The net balance of intercompany obligations owed to Electronics
by Sensors & Systems and Defense was $3.9 million on June 28, 1997. At the
Distribution date and including the effects of the cash transfer, management
estimates the net intercompany obligations of Electronics to Sensors & Systems
and Defense will be approximately $4.0 million. See Note 15 of Notes to
Combined Financial Statements.
 
  Management anticipates the cash transfer will be funded by a combination of
Sensors & Systems' existing cash balances and new borrowings by Sensors &
Systems of up to $9.0 million as described under "Financing--Bank Credit
Facilities" below. The net intercompany obligations of Electronics will be
assumed by Technologies and all the other assets and liabilities of Sensors &
Systems and Defense will be contributed to Technologies as

part of the Distribution. Technologies is establishing a credit facility with
Canadian Imperial Bank of Commerce ("CIBC"). There can be no assurance that
Sensors & Systems or the Company will be able to obtain such financing on
terms acceptable to the Company or that such financing, if obtained, will be
sufficient for the Company's needs.     
 
LISTING AND TRADING OF TECHNOLOGIES COMMON STOCK
 
  There is not currently a public market for Technologies Common Stock. Prices
at which Technologies Common Stock may trade prior to the Distribution on a
"when-issued" basis (see the following paragraph) or after the Distribution
cannot be predicted. Until Technologies Common Stock is fully distributed and
an orderly market develops, the prices at which trading in such stock occurs
may fluctuate significantly. The prices at which Technologies Common Stock
trades will be determined by the marketplace and may be influenced by many
factors, including, among others, the depth and liquidity of the market for
Technologies Common Stock, investor perception of Technologies and of the
industries in which Technologies operates, Technologies' dividend policy and
general economic and market conditions.
 
  In "when-issued" trading, contracts for the purchase and sale of shares of
stock are made prior to the issuance of such shares in the same manner as
currently issued shares, except that when-issued contracts are settled by
delivery of and payment for the shares on a date chosen by the particular
exchange on which such shares are to be listed. Ordinarily, in connection with
a distribution of stock such as described in this Information Statement, the
date fixed for settlement of when-issued contracts relating to such stock is
the sixth business day after distribution of such stock. Stockholders who may
wish to effect a when-issued trade in Technologies Common Stock should consult
their brokers for additional details.
   
  Technologies Common Stock has been approved for listing on the Nasdaq
National Market System, upon notice of issuance, under the symbol "BEIQ."
Technologies initially will have approximately 400 stockholders of record and
an additional 800 beneficial holders, based on the number of record holders
and the estimated number of beneficial holders of Electronics Common Stock at
September 22, 1997, and approximately 7,115,000 shares of Technologies Common
Stock will be outstanding. The Transfer Agent and Registrar for the
Technologies Common Stock will be ChaseMellon Shareholder Services, L.L.C. For
certain information regarding options to purchase Technologies Common Stock
that are expected to become outstanding after the Distribution, see "--Other
Consequences of the Distribution--Stock Options" and "New Incentive Plans of
BEI Technologies, Inc.--1997 Equity Incentive Plan."     
 
  It is anticipated that certain investment banking firms will make a market
in Technologies Common Stock following the Distribution. Any such market
making activity may be discontinued at any time, without notice. There can be
no assurance that an active trading market in Technologies Common Stock will
develop, or, if a market does develop, at what prices Technologies Common
Stock will trade.
 
  Shares of Technologies Common Stock distributed to Electronics stockholders
in the Distribution will be freely transferable, except for securities
received by persons who may be deemed to be "affiliates" of the Company under
the Securities Act. Persons who may be deemed to be affiliates of the Company
after the Distribution generally include individuals or entities that control,
are controlled by, or are under common control with, the Company and may
include certain officers and directors of the Company as well as principal
stockholders of the Company, if any. Persons who are affiliates of the Company
will be permitted to sell their shares of Technologies Common Stock only
pursuant to an effective registration statement under the Securities Act or
pursuant to Rule 144 or another exemption from the registration requirements
of the Securities Act.
 
OTHER CONSEQUENCES OF THE DISTRIBUTION
 
  Dividend Policies. Electronics has paid a cash dividend of $.02 per share of
Electronics Common Stock each quarter since its initial public offering in
1989. The payment of future dividends, if any, by Electronics or the Company
will be at the discretion of the Electronics Board of Directors and the
Company's Board of Directors, respectively.
 
                                       8

  Certain Anti-takeover Effects. The Certificate of Incorporation and Bylaws
of the Company contain several provisions that may make the acquisition of
control of the Company more difficult or expensive. With respect to certain of
these provisions, the Certificate of Incorporation of the Company differs from
the Certificate of Incorporation of Electronics. In addition, the Board of
Directors of the Company has adopted a Stockholder Rights Plan that has
certain anti-takeover effects. See "Certain Anti-takeover Effects of Certain
Provisions of the Certificate of Incorporation, the Bylaws and State Law" and
"Stockholder Rights Plan."
   
  Stock Options. Holders of vested incentive and nonstatutory stock options to
purchase Electronics Common Stock ("Vested Options") will be entitled to
exercise such Vested Options prior to the Record Date and thereafter to
receive shares of Technologies Common Stock as part of the Distribution.
Holders of Vested Options who do not exercise such Options prior to the Record
Date, together with holders of unvested incentive and nonstatutory stock
options to purchase Electronics Common Stock ("Unvested Options"), will have
such unexercised Vested Options and such Unvested Options converted to vested
and unvested incentive stock options and nonstatutory stock options, as
appropriate, to purchase Technologies Common Stock issued under the 1997
Technologies Equity Incentive Plan. As a result of the conversion to vested
and unvested incentive stock options and nonstatutory stock options to
purchase Technologies Common Stock, the Vested Options and Unvested Option to
purchase Electronics Common Stock will be cancelled. Based on options to
purchase Electronics Common Stock outstanding as of the Record Date, it is
anticipated that approximately 318,000 options to purchase shares of
Technologies Common Stock will be issued pursuant to the conversion. The
conversion will be based on the following criteria:     
 
    (i) the excess of the aggregate fair market value of the shares of
  Technologies Common Stock subject to the option immediately after the
  conversion over the aggregate option price of such shares may not be more
  than the excess of the aggregate fair market value of the shares of
  Electronics Common Stock subject to the option immediately before such
  conversion over the aggregate option price of such shares;
 
    (ii) on a share by share comparison, the ratio of the option price to the
  fair market value of the shares of Technologies Common Stock subject to the
  option immediately after the conversion may not be more favorable to the
  optionee than the ratio of the option price to the fair market value of the
  shares of Electronics Common Stock subject to the option immediately before
  the conversion; and
 
    (iii) the new option does not give the option holder additional benefits
  that such holder did not have under the old option.
   
  RESTRICTED STOCK. As of August 1, 1997, 352,550 shares of Electronics'
Common Stock had been issued and remain outstanding pursuant to awards of
restricted stock granted under the Electronics' 1992 Restricted Stock Plan
("Electronics' Restricted Stock"), including 94,636 shares issued to
individuals who will continue as directors or officers of the Company after
the Distribution. See "Executive Compensation--Executive Compensation Prior to
the Distribution--Summary Compensation Table." In addition, 257,914 shares of
Electronics Restricted Stock have been issued to individuals who will continue
as employees of the Company or a subsidiary of the Company after the
Distribution.     
 
  Each holder of the shares of Electronics Restricted Stock will receive as a
result of the Distribution of Technologies Common Stock vested and unvested
shares in amounts equal to the number of vested and unvested shares of
Electronics Restricted Stock held by such holder on the Record date. Based on
the number of shares of Electronics Restricted Stock outstanding on August 1,
1997, it is anticipated that a total of 352,550 shares of Technologies Stock
will be issued in connection with the Distribution to holders of Electronics
Restricted Stock.
 
  The Company has adopted a 1997 Equity Incentive Plan under which
consultants, employees and directors of the Company are eligible to receive
bonus stock awards. See "New Incentive Plans of BEI Technologies, Inc.--1997
Equity Incentive Plan."

                                   FINANCING
 
  Electronics' practice has been to incur long-term debt at the parent company
level rather than the subsidiary level, even when the funds obtained from such
borrowings have been used in the businesses of its subsidiaries. Accordingly,
financing requirements of Sensors & Systems generally have been funded through
intercompany accounts with Electronics.
 
BANK CREDIT FACILITIES
   
  In order to support its initial funding needs, including the transfer by
Sensors & Systems of up to $9.0 million to Electronics prior to the
Distribution to repay a portion of amounts payable to Electronics, Sensors &
Systems plans to borrow up to $9.0 million under a note from Canadian Imperial
Bank of Commerce. After the Distribution, Technologies is establishing a line
of credit with CIBC. See "The Distribution--Related Transactions--Financing
Transactions". Interest on borrowings under the line of credit will be based
upon either the Prime Commercial Lending Rate of CIBC or the rate which would
be offered by CIBC to prime banks in the interbank Eurodollar market,
depending on the term of the loan. Management believes that as a result of the
Distribution, Technologies will be able to obtain new financing on more
favorable terms than new financing Electronics could obtain absent the
Distribution. However, there can be no assurance that Sensors & Systems or
Technologies will be able to obtain such financing from CIBC or other sources
on terms acceptable to Technologies or that such financing if obtained will be
sufficient for Technologies needs.     
   
  Under the line of credit, CIBC will also issue standby letters of credit. At
the Effective Date, approximately $0.4 million is expected to be available to
fund letters of credit issued on behalf of the Company.

                                (IN THOUSANDS)
 
  The following table sets forth, as of June 28, 1997, the capitalization of
Technologies on a historical basis, and on a pro forma basis giving effect to
the Distribution, including the borrowing of up to $9.0 million by Sensors &
Systems, the transfer of up to $9.0 million in cash to Electronics to repay a
portion of amounts payable from Sensors & Systems to Electronics, and the
assumption by Technologies of net intercompany obligations of Electronics to
Sensors & Systems and Defense, estimated to be approximately $4.0 million at
the time of the Distribution. Technologies intends to establish a bank line of
credit. There can be no assurance that Sensors & Systems or Technologies will
be able to obtain such financing on terms acceptable to the Company or that
such financing, if obtained, will be sufficient for the Company's needs. This

                                 THE BUSINESS
 
                     INTRODUCTION AND HISTORICAL OVERVIEW
 
  Prior to the Effective Date, the distributing company, Electronics, operated
two separate businesses; namely, that of:
 
  1.) BEI Medical Systems Company, Inc., its 82% owned subsidiary (on a fully
diluted basis); and
 
  2.) BEI Sensors & Systems Company, Inc., its 100% owned subsidiary.
 
  In addition, Electronics produced rocket-propelled ordnance systems for
military use through its subsidiary, Defense Systems Company, Inc. ("Defense
Systems" or "Defense") in fiscal 1996 and prior years. (See Combined Financial
Statements and Note 2 thereto regarding discontinuance of the Defense Systems
segment.)
 
  The management and Board of Directors of Electronics have concluded that it
is in the best interests of Electronics and its stockholders for Electronics
to focus exclusively on the Medical Systems business and to create a separate
company to focus on and further grow the Sensors & Systems business and to
discontinue the operations of the Defense Systems segment. It will do so by
distributing all of the outstanding common stock of a newly formed, wholly
owned subsidiary, BEI Technologies, Inc., to Electronics' stockholders.
Electronics is distributing the shares of Technologies Common Stock based on
management's belief that each of its businesses would enjoy substantially
improved performance and access to capital markets if its business strategy,
organization and employee incentives were tightly focused on closely
associated products and markets. For a more complete discussion of the
business reasons for the distribution, see "The Distribution--Reasons for the
Distribution."
   
  BEI Technologies, Inc., a Delaware corporation newly organized in June 1997,
is currently a wholly-owned subsidiary of Electronics. As of the Effective
Date it will be the parent company of Sensors & Systems, a Delaware
corporation, which designs, manufactures and sells advanced electronic
products to control and drive the motion of machinery and equipment.
Technologies will also be the indirect parent company of Defense, a Delaware
corporation, which from inception through fiscal 1996 manufactured the HYDRA
70 rocket system. Sensors was originally incorporated in 1983, as Motion
Systems Company, Inc. Defense was originally incorporated in 1983 as Defense
Systems Company, Inc.     
 
  Technologies' principal executive offices are located at One Post Street,
Suite 2500, San Francisco, California 94104 (telephone number (415) 956-4477).
   
  "BEI" and "BEI GyroChip" are registered trademarks of the Company. Certain
other trademarks of the Company are used in this Information Statement.     
   
  Technologies has filed with the Commission the Registration Statement under
the Exchange Act with respect to its Common Stock described herein. The
Registration Statement became effective on September   , 1997. This
Information Statement does not contain all of the information set forth in the

Washington, D.C. 20549 or at branch locations listed on page iv, and copies of
all or any part thereof may be obtained from the Commission upon payment of
the charges prescribed by the Commission.     
 
  Following the Distribution, the Company will be required to comply with the
reporting requirements of the Exchange Act and will file annual, quarterly and
other reports with the Commission. The Company will also be subject to the
proxy solicitation requirements of the Exchange Act and, accordingly, will
furnish audited financial statements to its stockholders in connection with
its annual meeting of stockholders.

                          DESCRIPTION OF THE BUSINESS
                           OF BEI TECHNOLOGIES, INC.
 
BUSINESS SUMMARY AND STRATEGY
 
  The principal business of Technologies is carried out by its 100% owned
subsidiary, Sensors & Systems. Sensors & Systems designs, manufactures and
sells electronic devices that provide vital sensory input for the control
systems of advanced machinery and automation systems. These sensors, most of
which are concerned with physical motion, provide the information that is
essential to logical, safe and efficient operation of sophisticated machinery.
 
  The Company's long-term strategy is to provide, on a global basis, selected
advanced intelligent sensors based on proprietary technology. Technologies'
management believes that intelligent sensory input to machine control systems
and computers will be increasingly crucial to the productive functioning of a
modern economy. Accordingly, Sensors & Systems' goal is to maintain, develop
and acquire a diverse offering of advanced sensor products. In addition, the
Company will manufacture and sell certain products--such as brushless D.C.
motors--that are complementary to its sensor product line. Finally, the
Company will target proprietary, high margin niche markets for subsystems and
end products in which its sensors and complementary products play an enabling
role. The Company's near term initiatives include: (a) broad commercialization
of the "yaw" quartz rate sensor for the automotive industry (as described
below); (b) development and commercialization of internally developed
technologies that have broad applications and that management believes to be
promising; and (c) expansion of the product line through acquisitions of
complementary technologies.
 
  A key feature of the Company's strategy is to be widely recognized as the
most capable source for the sensor categories it has selected. Its traditional
emphasis is on highly engineered motion sensing components and assemblies. The
Company believes it differentiates itself by offering (a) appropriate
technology to solve a customer problem (including innovative proprietary
technology); (b) quality service; and (c) engineering assistance in
recommending and prescribing technical solutions for its customers'
applications. Sensors' product are not sold as commodities. Its strategy is to
provide technical advice and customer service that, together with the products
themselves, create value and give the customer confidence that the product has
been expertly prescribed and applied.
 
  By way of more specific examples, the Company's engineers regularly address
the following typical machine control requirements of customers:
 
  (1) A pick and place robot needs to know how far its elbow and wrist joints
have moved in order to control the speed and position of its "hand."
 
  (2) After a power outage, an elevator system needs to know exactly where
each car is before permitting motion to resume. (Is the car between floors or
not? Are the doors open or closed?) In both the foregoing examples, the
Company's encoders could measure speed, distance, or exact location.
 
  (3) An antenna on a moving ship needs to be actively stabilized so that the
antenna will continuously point at a satellite or another ship's pencil beam
laser signal. For such an application the Company might provide its
proprietary "GyroChip" quartz rate sensor. It might also provide motor-
encoders and actuators to drive the compensating action of such a system.
 
  (4) Some luxury automobiles now have computer-controlled stability
enhancement systems to assist drivers in maintaining control of the vehicle in
slippery conditions. In some of these systems one of the Company's sensors
tells the computer system the present direction and angle of the steering
wheels, while another of the Company's sensors instantly measures and reports
the presence of "yaw" forces which--if not corrected--could cause the vehicle
to spin out or "fishtail". The automation system in this case relies on
sensors to compare the driver's indicated directions and the actual result.
The system can then take corrective action automatically. Here the Company
provides special "GyroChip" quartz sensors as well as encoder and
potentiometer combinations.
 
                                      13
<PAGE>
 
   
  (5) Advanced engine control systems in tractors, trucks, and materials
handling and construction equipment need to know throttle position data in
order to assure efficient and clean combustion and safe and reliable gear
changes and other automated functions. The Company's potentiometers provide
the necessary throttle position data.     
 
  (6) Semiconductor production equipment requires extremely fast yet accurate
control of start-move-stop action on x-y positioners and tools. The Company's
magnetic actuators provide the energizing force for such tasks.
 
  (7) Process automation systems and various medical systems such as those for
cryosurgery and respiration therapy require compact, high reliability pressure
measurement and fast acting valves, which are accommodated by the Company's
silicon pressure sensors and/or magnetic actuators.
 
CUSTOMERS AND MARKETS
 
  The foregoing examples illustrate a few of the thousands of machine control
situations for which the sensors of the Company are used. Customers who buy
the Company's products are makers and users of many different kinds of
machinery and systems used in diverse markets and industries. Important market
categories include factory automation, process automation, transportation
(including cars, trucks, mass transit, construction and farm equipment),
health care and scientific equipment, and military, space and
telecommunications.
 
  The Company considers its large number of customers and the vast scope of
existing and potential applications for its products to be a source of the
Company's existing business strength and an opportunity for substantial long
term growth.
 
  The Company's brands have been well established in North America for many
years and were distributed during the past fiscal year through Sensors &
Systems' direct sales force to more than 6,400 different commercial customers,
principally in the United States. These customers included both end users and
original equipment manufacturers. The value of individual orders from
commercial customers--which account for approximately two thirds of total
sales--is typically less than $100,000.
 
  Sales from continuing operations to the U.S. Government (or prime
contractors who manage government funded projects) represented approximately
27% of the Company's sales in fiscal 1996, 32% in fiscal 1995 and 40% in
fiscal 1994. No commercial customer accounted for more than 10% of sales in
fiscal year 1996, 1995 or 1994. The Company sells approximately 10% of its
products in international markets. The Company has initiated actions which it
believes will increase its penetration of international markets.
 
  The Company also seeks to use its proprietary sensor capabilities to create
value-added subsystems or products. The goal is to make such high margin
products, enabled by the Company's proprietary technology, a growing part of
the Company's business. For example, the Company's success in providing
components for pointing and stabilizing telecommunications antennae has led to
it exploring the market for a unique stabilized platform for optical systems
that the Company may offer as a product.
 
PRODUCTS AND PROPRIETARY SYSTEMS
 
  The Company's main product groups may be categorized as follows:
 
  1. Sensors (for motion and pressure measurement),
  2. Products Complementary to Sensors (motors and actuators), and
 
  3. Engineered Subsystems (such as inertial guidance units, electronic servo
control systems, scanner assemblies and cryocoolers)
 
                                      14
<PAGE>
 
  A more detailed description of the products and systems designed,
manufactured and sold by the Company follows below:
 
 Sensors:
 
  Shaft Encoders. Shaft encoders translate the motion of rotating shafts
directly into digitally coded electronic signals. These digitally coded
signals facilitate interpretation of the sensed motion by microcomputer
processors that are used to control the operation of machinery and equipment.
Sensors & Systems offers a wide array of encoders to serve a variety of
applications. The most common applications are for factory automation, office
automation, and transportation equipment, but specialized versions are also
used for military and space hardware. Value-added assemblies which employ
shaft encoders include servo motors and servo drive electronic control
systems.
 
  Precision Potentiometers. Similar in basic function to encoders,
potentiometers measure motion by analog (not digital) changes in electrical
potential. These changes may sometimes be subsequently translated into digital
code. Potentiometers are used as economical motion or position-sensing devices
for throttle, steering, suspension, and seat and mirror position controls in
automobiles and in some heavy equipment, such as earth movers, and
construction and farm machinery. They are also used as position sensors in
such applications as actuators on molding presses, saw mills and numerous
other types of industrial equipment and in oil well logging calipers.
Incorporating Sensors & Systems' potentiometer technology with its proprietary
shaft encoder technology has resulted in a highly engineered steering wheel
position sensor used for intelligent stability control systems for automobiles
and potentially for other vehicles in the future.
 
  Rate Sensors and Accelerometers. These products provide precise and reliable
measurement of minute linear and angular motion for control, guidance and
instrumentation. In general, these devices operate without need for direct
linkage to the driving mechanisms. Such measurements are required for heading
and attitude reference instruments in aircraft and missiles, stabilization of
satellites, pointing and control of antennae on aircraft, ships and other
moving platforms, navigation of oil well drill bit assemblies, and for
intelligent vehicle stability and navigation systems in the automotive
industry.
 
  Mechanical accelerometers and rate sensors using traditional technology
(e.g., a moving mass suspended by a pivot and jewel mechanism) rely on the
movement of complex machined metallic parts to measure motion. In contrast,
Sensors & Systems' miniature, solid state accelerometers and rate sensors are
based on innovative and proprietary chemical micro-machining of a single
element from crystalline quartz using photolithographic methods similar to
those used in the manufacture of silicon semiconductor chips. The advantages
of quartz rate sensors and accelerometers over traditional mechanical units
are increased reliability, reduced size, and lower production and life cycle
costs.
   
  BEI GyroChip(R) Sensors. The Company's family of GyroChip quartz rate
sensors, developed primarily for commercial gyro applications, have found use
in such varied requirements as navigation of autonomous (robotic) guided
vehicles, ocean buoy and sea-state monitoring, and stabilization of pointing
systems for antennas and optical systems. The most frequent use of GyroChip
units is as yaw sensors in stability control or spin-out prevention systems
for automobiles. GyroChip sensors provide performance suitable for commercial
applications while offering ruggedness, longer life and smaller size at a
lower cost than military versions of quartz rates sensors.     
 
  Pressure Sensors. Pressure sensors measure absolute or differential pressure
from vacuum to 10,000 psi. Various sensing technologies are used such as thick
film potentiometric devices for high temperature applications; thin film
devices used for commercial/industrial systems; and silicon micromachined
structures used for high volume medical, commercial and automotive markets.
The Company provides standard products as well as application specific
solutions to pressure measurement requirements.

  Micro-Electromechanical Sensors (MEMS). MEMS are a new category of ultra
small devices, usually micro-machined from crystalline materials such as
quartz or silicon. The GyroChip sensors and other quartz devices discussed
above are examples of MEMS currently being sold by Electronics. Management
expects Sensors & Systems' MEMS research and development programs to lead to
new devices for sensing motion, pressure and other physical parameters.
 
 Products Complementary to Sensors:
 
  Brushless DC Motors. Brushless DC Motors give high performance and
efficiency in compact, lightweight packages and ease of interface with
microprocessors. The motors, which feature high energy magnets, are
characterized by long life and low acoustic and electrical noise. They are
well suited to high speed, high reliability applications, such as in operating
rooms where the risk of sparks from a brush motor would be hazardous or where
electrical noise could disrupt computers or computer-controlled equipment.
 
  Magnetic Actuators. Magnetic actuators are used in place of motors or
solenoids to achieve precise control of short stroke linear or limited rotary
motion. Actuators using very high energy magnets are also produced for
specialized applications requiring intense force, torque or acceleration
relative to the size of the device.
 
 Engineered Subsystems:
 
  Avionics Controls. In 1995, Electronics discontinued production of rocket
propelled ordnance systems. Certain avionics control units (electronic black
boxes), which were part of the rocket system product mix, continue in backlog,
however, and will in the future be reported as a part of Technologies'
continuing Sensors & Systems business.
 
  Cryocoolers. The Company's proprietary, compact and lightweight stirling
cycle refrigerators are designed for cooling advanced electronic vision
sensors to liquid nitrogen temperatures. These cryocoolers are utilized in
infrared cameras used in surveillance, night vision pilotage systems and
superconducting applications.
   
  Inertial Measurement Units (IMU's). These subsystems are a fundamental
element of virtually all inertial navigation and position or attitude
reporting systems. Even systems that rely on the Global Positioning Satellite
(GPS) network frequently must have an IMU built in to assure a back-up in case
the GPS signal is interrupted. Technologies' quartz rate sensors have made new
breakthroughs in size, reliability and cost for the proprietary IMU subsystems
Technologies builds.     
 
  Scanner Assemblies. Scanner assemblies are an integral subsystem of the
optics in military night vision systems that guide the infrared image to the
focal plane sensor array. These subsystems consist of spinning or
reciprocating mirrors, a motor and an encoder in a precision servo loop. The
Company's motion control know-how helps assure that the scanner delivers
jitter-free, well-resolved images.
 
  Servo Systems. Servo Systems are closed-loop electronic systems that control
the position or velocity of rotating shafts or other moving parts by accepting
a desired rate or position input from computers or keyboards, monitoring the
position or rate of movement (using an appropriate encoder or other sensor)
and constantly providing feedback that indicates whether the desired
performance has been achieved.
 
BACKLOG
 
  The Company's commercial operations typically ship standard products within
30 to 90 days after receipt of a purchase authorization. Management of the
Company believes that its competitive position depends in part on minimizing
the time that elapses between receipt and shipment of an order. Products that
require special analysis, design or testing, such as those produced for
customers in the aviation, defense or space technology markets, are generally
shipped from six to eighteen months after receipt of the purchase
authorization.

       Backlog.................................................. $47,197 $42,239
</TABLE>
 
  Backlog includes aggregate contract revenues remaining to be earned by the
Company over the next twelve months of scheduled deliveries under existing
contracts. Some contracts undertaken by Sensors & Systems extend beyond one
year. Accordingly, portions of such contracts are carried forward from one
year to the next as part of backlog. Approximately 46% of the backlog as of
June 28, 1997 is scheduled for shipment during fiscal 1997; all of the
remainder of the backlog is scheduled for shipment during fiscal 1998.
 
  In the case of U.S. Government contracts, backlog includes only the
applicable portion of contracts that are fully funded by a procuring
Government agency. All U.S. Government contracts and subcontracts are subject
to termination by the U.S. Government for convenience. There can be no
assurance that all existing contract backlog will eventually result in revenue
and, accordingly, the amount of backlog at any date is not necessarily a
reliable indicator of future revenue or profitability trends.
 
COMPETITION
 
  Competitors for various products offered by the Company are found among
certain divisions or product lines of large, diversified companies such as
Allied-Signal, Boeing, Danaher Corp., Litton, Northrop, Honeywell and
Rockwell. Smaller or product-specific companies, some of whose products
compete include Encoder Products, Kollmorgen, Kulite Semiconductor, Dynamics
Research Corp., Pacific Scientific, Papst, Renco Encoders, Axsys Technologies,
and Servo Magnetics.
 
  In its principal markets, the Company believes that competition is based
primarily on design, performance, reliability, price, delivery, service and
support. The Company believes that it competes favorably with respect to these
factors.
 
MANUFACTURING
 
  The Company's manufacturing operations provide a mix of standard catalog
products and products designed to meet the specialized requirements of a
particular customer. The Company's products, whether standard or "custom", are
normally manufactured in response to customers' orders and are in general not
held as finished goods. Most are assembled from parts or subassemblies that
are proprietary to the Company.
 
  A special code pattern generator designed by and proprietary to the Company
is used to produce shaft encoder parts. Special quartz micromachining
equipment is used for the production of QRS units. Special high throughput
automated or semi-automated equipment is used for the production of QRS
assemblies, brushless motors and potentiometers. Some parts are fabricated
under clean room conditions.
 
RESEARCH AND DEVELOPMENT
 
  The major research and development focus has been to improve performance and
yield of existing products, with special emphasis on the quartz sensors used
in high accuracy IMU's and high volume yaw rate sensors for the automotive
industry. Substantial effort has also been devoted to the development of
manufacturing methods necessary to deliver competitive prices and quality in
the automotive market. Other development has focused on expanding applications
of existing sensors.
 
  The Company has also produced prototypes of future products incorporating
silicon micro-electromechanical sensors (MEMS) geared towards next generation
requirements for automotive, medical, industrial and aerospace markets.
 
 
                                      17
<PAGE>
 
  Management of the Company believes that its future success will depend in
part on its ability to continue to enhance its existing products, and to
develop and introduce new products that maintain technological leadership,
meet a wider range of customer needs and achieve market acceptance.
Accordingly, the Company's internally funded research, development and related
engineering expenditures were approximately $3.6 million, $4.0 million and
$6.1 million in fiscal 1996, 1995 and 1994, respectively. In addition,
customer funded research and development expenditures charged to cost of sales
were $3.0 million, $6.3 million and $5.4 million, respectively, for the same
periods.
 
EMPLOYEES
   
  As of June 28, 1997, the units that will comprise Technologies had 948
employees, including 122 in research, development and engineering, 74 in
administration, 71 in marketing and sales, and 681 in operations. The Company
believes that its continued success depends on its ability to attract and
retain highly qualified personnel. The Company's employees are not covered by
collective bargaining agreements. The Company has not experienced any work
stoppages and considers its relationship with its employees to be good.     
 
INTELLECTUAL PROPERTY
 
  The Company relies primarily upon trade secrets and know-how to develop and
maintain its competitive position. In addition the Company and its
subsidiaries own 82 U.S. patents and 50 foreign patents with expiration dates
ranging from October 1997 to August 2014. Because many of these patents relate
to technology that is important to certain of the Company's products, the
Company considers these patents to be significant to its business.
 
  While management believes that the Company's intellectual property rights
are important, management also believes that because of the rapid pace of
technological change in the industries in which the Company competes, factors
such as innovative skills, technical expertise, the ability to adapt quickly
to technological change and evolving customer requirements, product support
and customer relations are of equal competitive significance.
 
ENVIRONMENTAL MATTERS
 
  The Company uses certain controlled or hazardous materials in its research
and manufacturing operations and, as a result, is subject to federal, state
and local regulations governing the storage, use and disposal of such
materials. Management of the Company believes that it is currently in
compliance with such laws and regulations.

             NOTES TO SELECTED UNAUDITED PRO FORMA FINANCIAL DATA
 
  The unaudited pro forma condensed combined balance sheet as of June 28, 1997
and combined statements of operations for the nine months ended June 28, 1997
and for the year ended September 28, 1996, give effect to the following
adjustments:
 
  (1) Reflects borrowing of $9.0 million by Sensors & Systems and transfer of
up to $9.0 million in cash to Electronics as repayment of a portion of amounts
payable by Sensors & Systems to Electronics.
 
  (2) Reflects the assumption by Technologies of net intercompany obligations
payable by Electronics to Sensors & Systems and Defense, estimated to be
approximately $4.0 million at the time of the Distribution.
   
  (3) Reflects interest expense incurred on the $9.0 million of proforma
indebtedness as if the debt was issued by the Company at the beginning of each
period presented using the Company's incremental borrowing rate, which is
based on the terms of Electronics' currently available line of credit.
Management believes that as a result of the Distribution, Technologies will be
able to obtain financing on more favorable terms than new financing
Electronics could obtain absent the Distribution. However, there can be no
assurance that Sensors & Systems or Technologies will be able to obtain such
financing on terms acceptable to the Company or that such financing , if
obtained, will be sufficient for the Company's needs. The pro forma income tax
benefit of such interest charges has been computed using the Company's
historical tax rate.     
 
  (4) Pro forma earnings from continuing operations per share as adjusted,
reflects the impact of the adjustments described above.
   
  (5) Pro forma earnings from continuing operations per common and common
equivalent share are computed using the weighted average number of shares of
common stock outstanding plus the dilutive effect of common equivalent shares
from stock options and restricted stock using the treasury stock method
assuming that upon exercise the holder would receive one share of Technologies
common stock for each share of Electronics common stock acquired through
exercise of such options.

COMPARISON OF NINE MONTHS ENDED JUNE 28, 1997 AND JUNE 29, 1996
 
RESULTS OF OPERATIONS
 
 Net Sales
 
  Net sales from continuing operations for the first nine months of fiscal
1997 increased $3.0 million or 4.3% from the prior year. Sales of automotive
and other commercial products increased $1.9 million and $6.7 million,
respectively, but were partially offset by decreases in sales to government
contractors or subcontractors of $5.5 million.
 
 Cost of Sales
 
  Continuing operations cost of sales as a percentage of net sales increased
from 62.2% to 65.0%. Continuing operations incurred cost overruns on the
development of some products for aerospace applications. In addition, average
costs of goods sold as a percentage of sales for new automotive applications
are higher than for other commercial products due to start-up efforts.
 
 Selling, General and Administrative Expenses
 
  Continuing operations selling, general and administrative expenses as a
percentage of net sales decreased from 25.8% in the first nine months of
fiscal 1996 to 25.5% in the first nine months of fiscal 1997. Actual selling,
 
                                      25
<PAGE>
 
   
general and administrative expenses increased from $18.5 million in the first
nine months of fiscal 1996 to $19.0 million in the first nine months of fiscal
1997, including $1.7 million in charges associated with the settlement of a
legal dispute by arbitration in the first quarter of fiscal year 1997. See
Note 11 of Notes to the Combined Financial Statements.     
 
 Research, Development and Related Expenses
 
  Research, development and related expenses as a percentage of net sales for
the first nine months of fiscal 1997 have increased 0.5% from the same period
in fiscal 1996 due to increased research spending to support the production of
MEMS and the development of automotive and other commercial products.
 
 Interest Expense and Other Income
 
  Interest costs in the first nine months of fiscal 1997 decreased by $0.5
million from the same period in fiscal 1996. The lower interest expense is the
result of the repayment of $5.6 million of debt in the first quarter of 1997.
 
 Income from Continuing Operations
 
  The decline in income from continuing operations, from $2.7 million in the
first nine months of fiscal 1996 to $1.8 million in the first nine months of
fiscal 1997, primarily reflects the after tax charge in fiscal year 1997 of
$1.1 million incurred in connection with an arbitration to settle a royalty
dispute and a 2.8% decrease in gross profit as a percentage of sales.
 
 Income from Discontinued Operations
 
  In June 1997, the Board of Directors of Electronics approved a formal plan
for discontinuation of the operations of the Defense Systems business segment.
This segment was primarily a manufacturer of Hydra 70 ("H 70") military
rockets whose production was shut down at the end of fiscal 1996. Accordingly,
the results of operations of the Defense Systems segment have been reported as
discontinued operations for all periods presented. Defense Systems' income
decreased slightly from $0.6 million in the third quarter of fiscal 1996 to
$0.5 million in the third quarter of fiscal 1997. Defense Systems' improved
gross profit on the non-H 70 products, together with a $1.3 million decline in
selling, general and administration expenses due to the closure of the H 70
production line, resulted in income from discontinued operations increasing to
$1.4 million in the first nine months of fiscal 1997 from $1.1 million in the
first nine months of fiscal 1996.
 
 Liquidity and Capital Resources
 
  During the first nine months of fiscal 1997, operations provided $2.9
million in cash. Operating cash inflows consisted primarily of income adjusted
for the positive impact of non-cash charges from depreciation and amortization
of $4.3 million, and changes in assets and liabilities of discontinued
operations of Defense Systems of $2.7 million. Offsetting these inflows were
inventory increases of $3.1 million, the negative impact of a change in
deferred taxes of $1.8 million, and a net decrease in trade payables and
accrued expenses and other liabilities of $3.6 million, primarily due to a
payment $5.3 million of amounts accrued in fiscal 1996 and in the first
quarter of fiscal 1997 in connection with the final settlement of an
arbitration. See Note 11 of Notes to the Combined Financial Statements.
 
  Cash used in investing activities in the first nine months of fiscal 1997
consisted primarily of $6.0 million for capital expenditures, which is
consistent with spending in the first nine months of the prior fiscal year.
Capital equipment requirements may increase in future periods and the Company
may expand the use of lease financing to fund such requirements.
 
  The Company had no material capital commitments at June 28, 1997.

  The Internal Revenue Service (IRS) audited Electronics' income tax returns
for the fiscal years 1993 through 1995. In the third quarter of fiscal year
1997, Electronics reached a settlement with the IRS for all issues raised for
these years, resulting in the payment of $1.7 million in additional taxes for
those years, of which approximately $1.0 million relates to Technologies. The
settlement related primarily to the timing of deductions resulting from
acquisitions made by Electronics. The payment of these additional taxes
resulted in an increase in deferred tax assets and did not affect the
provision for income taxes in the third quarter of fiscal year 1997.
 
  As of June 28, 1997, the Company was in compliance with all financial
covenants on outstanding debt.
   
  In connection with the Distribution and subject to the noteholders
agreement, the Company will assume existing indebtedness of Electronics in the
amount of approximately $22.4 million. In order to support its initial funding
needs, including the transfer by Sensors & Systems of up to $9.0 million to
Electronics prior to the Distribution to repay a portion of amounts payable to
Electronics, Sensors & Systems plans to borrow up to $9.0 million under a note
from Canadian Imperial Bank of Commerce. After the Distribution, Technologies
intends to establish a line of credit with CIBC. See "The Distribution--
Related Transactions--Financing Transactions". Interest on borrowings under
the line of credit will be based upon either the Prime Commercial Lending Rate
of CIBC or the rate which would be offered by CIBC to prime banks in the
interbank Eurodollar market, depending on the term of the loan. Management
believes that as a result of the Distribution, Technologies will be able to
obtain new financing on more favorable terms than new financing Electronics
could obtain absent the Distribution. However, there can be no assurance that
Sensors & Systems or Technologies will be able to obtain such financing from
CIBC or other sources on terms acceptable to the Company or that such
financing if obtained will be sufficient for the Company's needs.     
 
FISCAL YEARS 1996, 1995 AND 1994
 
 Net Sales
 
  In fiscal 1996, net sales from continuing operations increased 6.9% to $96.7
million from $90.5 million in fiscal 1995. This increase reflects the
continued growth in sales of commercial product lines, including those for
industrial, automotive and medical markets.
 
  In fiscal 1995, net sales from continuing operations increased 9.9% to $90.5
million from $82.4 million in fiscal 1994, primarily reflecting the continued
growth in sales of commercial product lines, including those for industrial,
automotive and medical markets.
 
  The Company's sales to international customers were approximately 11.3%,
10.7% and 9.6% of the Company's net sales from continued and discontinued
operations for fiscal 1996, 1995 and 1994, respectively.
 
 Cost of Sales
 
  During fiscal 1996, the Sensors & Systems segment cost of sales as a
percentage of sales from continuing operations remained relatively flat,
decreasing 0.3% to 62.5% from 62.8% in fiscal 1995. Cost of sales as a
percentage of sales increased 3.2% to 62.8% in fiscal 1995 from 59.6% in
fiscal 1994 primarily due to a lower priced product mix.
 
  Downward pressure on gross profit margins is expected to continue,
especially for military contracts. The Company's gross profit margins from
sales to the U.S. Government for military and space products are generally
lower than gross profit margins from sales of commercial and industrial
products. Management is continuing measures intended to reduce costs and
improve average margins.
 
 Selling, General and Administrative Expenses
 
  Selling, general and administrative expenses as a percentage of net sales
from continuing operations were 27.0%, 28.3% and 29.7% in fiscal 1996, 1995
and 1994, respectively.
 
                                      27
<PAGE>
 
  Fiscal 1996 selling, general and administrative expenses increased $0.6
million from $25.6 million in fiscal 1995 to $26.2 million. Selling, general
and administrative expenses increased to support operations selling commercial
products, with a portion of the increase offset by declines in operations
selling government products.
 
  Fiscal 1995 selling, general and administrative expenses increased to $25.6
million from $24.4 million in fiscal 1994. The Company experienced higher
selling, general and administrative expenses to support sales growth in
commercial product lines. In addition to selling, general and administrative
expense, the Company recorded a charge in the fourth quarter of fiscal 1995 in
the amount of 3.9% of net sales ($3.5 million) for royalty and related costs
incurred on the basis of an interim arbitration ruling.
 
 Research, Development and Related Expenses
 
  The Company's internally funded research, development and related expenses
as a percentage of net sales from continuing operations were 3.7%, 4.4% and
7.4% for fiscal 1996, 1995 and 1994, respectively.
 
  Research and development expenses declined slightly in fiscal 1996 as
engineering effort was shifted to manufacturing support as production of new
automotive sensors began to ramp up.
 
  Research and development spending in fiscal 1995 was concentrated in support
of the growth of the commercial product lines. Consequently, certain programs
were phased out while emphasis on development of sensors for the automotive
industry was increased.
 
  The Company believes that the continued timely development of new products
and enhancements to its existing products is essential to maintaining its
competitive position. Accordingly, the Company anticipates that such expenses
will increase in absolute amount, but may fluctuate as a percentage of sales
depending on the Company's success in acquiring customers or, in some cases,
U.S. Government funding.
 
 Interest Expense and Other Income
 
  Interest expense was $2.4 million, $2.3 million and $2.2 million in fiscal
1996, 1995 and 1994 respectively. Interest is paid primarily on the Senior
Note debt. There was no new long-term debt issued during fiscal 1996.
 
  Other income in fiscal 1996, 1995, and 1994 is comprised of royalty income
and interest income earned on highly liquid investments.
 
 Provision for Income Taxes for Continuing Operations
 
  The Company's effective tax (benefit) rate was 33.0%, (38.4%), and 50.2%,
for fiscal 1996, 1995 and 1994, respectively. The effective tax rate reflects
the statutory federal tax rate and the weighted average tax rate of the states
in which the Company conducts business. The fiscal 1996 tax rate reflects
realization of additional federal and state tax credits for research and
development identified in 1996. The fiscal 1995 effective tax rate was lower
than the effective rate in fiscal 1994 due to losses in certain states where
realization of the benefits of the losses is uncertain.
 
 Deferred Income Taxes
 
  At September 28, 1996, the Company had net deferred tax assets of $1,852,000
composed of deferred tax assets of $5,139,000, net of the valuation allowance
of $94,000, and deferred tax liabilities of $3,287,000. The Company believes
it is likely that the benefits of the deferred tax assets will be realized
through the reduction of future taxable income and the reversal of existing
deferred tax liabilities.
 
 Income (Loss) from Discontinued Operations
 
  Income (loss) for Defense Systems was $1.7 million, $(1.1) million and $0.4
million in fiscal 1996, 1995 and 1994, respectively. The fiscal 1996 income
reflects the receipt of a $3.6 million pre-tax settlement for a prior
 
                                      28
<PAGE>
 
year H 70 contract. The $(1.1) million loss in 1995 was due primarily to
additional contract completion costs of $1.5 million associated with the wind
up of rocket related business.
 
 Liquidity and Capital Resources
 
  During fiscal 1996, operations provided $13.5 million in cash, including
cash provided by discontinued operations of $6 million. Net income of $4.6
million plus non-cash charges for depreciation and amortization of $4.2
million and $1.7 million, respectively, and a decrease in deferred tax assets
of $0.7 million, were partially offset by inventory purchases of $2.2 million
and an increase in trade receivables of $0.8 million.
 
  Investing activities in fiscal 1996 consisted primarily of the purchase of
$3.6 million in capital equipment.
 
  The Company paid BEI Electronics, Inc. $4.3 million in fiscal 1996.
 
 Effects of Inflation
 
  Management believes that, for the periods presented, inflation has not had a
material effect on the Company's operations.
 
                                      29
<PAGE>
 
                                 RISK FACTORS
 
  The following factors are applicable to Technologies which is expected to
report as a single business segment. These factors should be considered in
evaluating Technologies and its business prospects. This Information Statement
contains forward-looking statements which involve risks and uncertainties. The
Company's actual results could differ materially from those anticipated in
these forward-looking statements as a result of certain factors, including
those set forth herein and elsewhere in this Information Statement.
 
COMPETITION
 
  Competitors for various products offered by Technologies' Sensors & Systems
business are noted above under "Description of the Business--Competition". In
addition, the Company also may compete with manufacturers of competing
technologies, such as resolvers, inductosyns, laser and fiber optic gyros and
magnetic encoders. Many of the Company's existing competitors in each market,
and also a number of potential entrants into these markets, have significantly
greater financial resources and manufacturing capabilities, are more
established, have larger marketing and sales organizations and larger
technical staffs. There can be no assurance that other companies will not
develop more sophisticated, more cost-effective or otherwise superior products
which could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
LIMITED MANUFACTURING EXPERIENCE; SCALE-UP RISK; PRODUCT RECALL RISK
 
  Technologies is in the process of scaling up production of its automotive
yaw sensors for the quantities required by the automobile market. The Company
has relatively limited experience in large-scale manufacturing. The Company
currently manufactures moderate quantities of its automotive yaw sensor in the
Concord, California facility and its steering sensor in the Tustin, California
facility. Manufacturers sometimes encounter difficulties in scaling up
production of new products, including problems involving production yields,
quality control and assurance, component supply and shortages of qualified
personnel. If such difficulties were encountered by the Company in
manufacturing scale-up, they could have a material adverse effect on its
business, financial condition and results of operations. There can be no
assurance that future manufacturing difficulties or product recalls, either of
which could have a material adverse effect on the Company's business,
financial condition and results of operations, will not occur.
 
CONTRACTING WITH THE U.S. GOVERNMENT
 
  Approximately 27%, 32% and 40% of the net sales of units comprising the
continuing operations of Technologies in fiscal 1996, 1995 and 1994,
respectively, were derived from contracts with the U.S. Government or under
subcontract to other prime contractors to the Government. Because a
significant portion of Technologies' business is derived from contracts with
the Department of Defense or other agencies of the Government, the Company's
business is sensitive to changes in Government spending policies, which can
have significant variations from year to year. At various times, the Company's
results have been adversely affected by contract cutbacks and there can be no
assurance that the Company's results of operations will not in the future be
materially and adversely affected by changes in Government procurement
policies or reductions in Government expenditures for products furnished by
the Company.
 
  Under applicable regulations, various audit agencies of the Government
conduct regular audits of contractors' compliance with a variety of Government
regulations. The Government also has the right to review retroactively the
cost records under most Government contracts. Contract prices may be adjusted
in the event the Government determines that the Company submits incomplete,
inaccurate or obsolete cost or pricing data. Government contracts and
subcontracts generally provide for either a fixed price, negotiated fixed
price or cost-plus-fixed-fee basis for remuneration. The majority of the
contracts with the Government are competitive fixed price or negotiated fixed
price contracts, although cost-plus-fixed-fee contracts were approximately 5%
of the Company's net sales from continuing operations in fiscal 1996. For
fixed price contracts, the Company bears the
 
                                      30
<PAGE>
 
risk of cost overruns and derives the benefits from cost savings. As a result,
greater risks are involved under fixed price contracts than under cost-plus
contracts because failure to anticipate technical problems, estimate costs
accurately or control costs during contract performance may reduce or
eliminate the contemplated profit or may result in a loss.
 
  All Government contracts contain termination clauses that allow the contract
to be terminated either for contractor default or for the convenience of the
Government. In the event of termination for the convenience of the Government,
the clause typically provides that the contractor will receive payment for
work-in-progress, including profit. To date, termination of Sensors & Systems'
contracts by the Government has not had any significant effect on the
Company's financial results. However, no assurance can be given that such
terminations will not have a materially adverse effect on the Company's
results of operations in the future.
 
  Portions of the Company's government business are sometimes classified. As a
result, the Company may be prohibited from disclosing the substance or status
of such business.
 
RESEARCH AND DEVELOPMENT
 
  The Company depends in part on its research and development initiatives to
provide new products and product improvements which will maintain the
Company's favorable reputation in its various markets. There can be no
assurance that the outcome of its research and development activity will yield
the desired results.
 
MANUFACTURING PROCESSES AND EQUIPMENT
 
  The Company manufactures certain products such as quartz rate sensors and
some shaft encoders using highly complex proprietary processes and equipment.
The possibility exists that equipment could be damaged or that process
disciplines and controls could be temporarily lost. Such events could disrupt
production, which could have a material adverse effect on the Company's
business and results of operations.
 
DEPENDENCE UPON KEY PERSONNEL
 
  The Company is dependent upon a number of key management and technical
personnel. The loss of the services of one or more key employees could have a
material adverse effect on the Company. The Company's success will also depend
on its ability to attract and retain additional highly qualified management
and technical personnel. The Company faces intense competition for qualified
personnel, many of whom are often subject to offers from competing employers.
There can be no assurance that the Company will be able to retain its key
employees, or that it will be able to attract or retain additional skilled
personnel as required. The Company does not currently maintain key person
insurance on any employee. See "Description of the Business of BEI
Technologies, Inc.--Employees" and "Directors and Executive Officers of the
Company."
 
DEPENDENCE UPON KEY SUPPLIERS
   
  Although the majority of the components used in Company products are
available from multiple sources, several components are built to Technologies'
specifications. Such components include quartz, supplied by Sawyer Research
Products, Inc. scanner motors, supplied by Litton Industries, Inc.; three
types of ASIC's, supplied by National Semiconductor Corporation, Honeywell
Inc. and Semtech Corp.; and two types of LED's, supplied by Optek Technology,
Inc. and Opto Diode Corp. While the Company currently relies on single
suppliers for these components, in each instance, the Company is aware of
alternative suppliers and believes the components could be manufactured by
these alternative suppliers with minimal supply reduction should the need
arise to change vendors. To date, the Company has not experienced any
significant interruptions in the supply of these components, but there can be
no assurance that there will not be a significant disruption in the supply of
such components in the future, or in the event of such disruption, that the
Company will be able to locate alternative suppliers of the components with
the same quality at an acceptable price. An interruption in the supply of
components used in the manufacture of the Company's products, particularly as
the Company scales up its manufacturing activities in support of commercial
sales, could have a material adverse effect on the Company's business,
financial condition and results of operations.     
 
                                      31
<PAGE>
 
AVAILABILITY AND COST OF ADDITIONAL FUNDS
 
  Management believes that new financing will be available to Technologies on
more favorable terms as a result of the Distribution than new financing for
Electronics absent the Distribution. However, Technologies has no assurance
that, as an independent public company, it will be able to obtain financing
upon terms as favorable as those obtained by Electronics prior to the
Distribution, or that available financing will be sufficient for the Company's
needs.
 
UNCERTAINTY OF TAX CONSEQUENCES
 
  As a condition to the completion of the Distribution, Electronics and the
Company will receive an opinion from Davis Polk & Wardwell to the effect that,
although the matter is not free from doubt, the Distribution will qualify as a
tax-free spin-off under Section 355 of the Code.
 
  The tax opinion will rely upon, among other things, certain representations
made by Electronics and Technologies to Davis Polk & Wardwell. If it were
subsequently determined that those representations were inaccurate or
incomplete, the conclusion in the tax opinion could not be relied upon. As
reflected in the tax opinion, the applicability of Section 355 to the
Distribution is complex and may be subject to differing interpretations.
Accordingly, there can be no assurance that the Internal Revenue Service will
not successfully challenge the applicability of Section 355 to the
Distribution, or assert that the Distribution fails the requirements of
Section 355 on the basis of facts either existing at the Effective Date or
that may arise after the Effective Date. See "The Distribution--Certain
Federal Income Tax Consequences of the Distribution."
 
NO PRIOR PUBLIC MARKET FOR COMMON STOCK; POTENTIAL VOLATILITY OF STOCK PRICE
 
  Prior to the Distribution, there has been no public market for Company
Common Stock, and there can be no assurance that an active public market for
the Common Stock will develop or will continue after the Distribution. Until
the Common Stock is fully distributed and an orderly market develops, the
prices at which the Common Stock trades may fluctuate significantly. The
market price of Electronics Common Stock has been subject to significant
fluctuation in recent years. Accordingly, the market price of Company Common
Stock may be subject to wide fluctuations in response to quarter-to-quarter
fluctuations in operating results, announcements of technological innovations
or new products by the Company or its competitors, general industry and market
conditions, changes in earnings estimates by analysts and other events or
factors.
 
ANTI-TAKEOVER EFFECTS OF DELAWARE LAW AND CERTAIN CHARTER PROVISIONS;
STOCKHOLDER RIGHTS PLAN
 
  The Company's Board of Directors has the authority to issue up to 2,000,000
shares of Preferred Stock and to determine the price, rights, preferences and
privileges of those shares without any further vote or action by the Company's
stockholders. The rights of the holders of Common Stock will be subject to,
and may be adversely affected by, the rights of the holders of any Preferred
Stock that may be issued in the future. While the Company has no present
intention to issue shares of Preferred Stock, such issuance, while providing
desirable flexibility in connection with possible acquisitions and other
corporate purposes, could have the effect of making it more difficult for a
third party to acquire a majority of the outstanding voting stock of the
Company. In addition, the Company is subject to the anti-takeover provisions
of Section 203 of the Delaware General Corporation Law (the "Delaware Law"),
and the Company's Certificate of Incorporation contains a fair price
provision, the combined effect of which prohibits the Company from engaging in
a "business combination" with an "interested stockholder" for a period of
three years after the date of the transaction in which the person became an
interested stockholder, unless the business combination is approved in a
prescribed manner. The application of Section 203 and the fair price provision
could have the effect of delaying or preventing a change of control of the
Company. The Company's Certificate of Incorporation provides for staggered
terms for the members of the Board of Directors. The staggered Board of
Directors and certain other provisions of the Company's Certificate of
Incorporation and Bylaws may have the effect of delaying or preventing changes
in control or management of the Company, which could adversely affect the
market price of the Company's
 
                                      32
<PAGE>
 
Common Stock. Furthermore, the Board of Directors of the Company has adopted a
Stockholder Rights Plan that has certain anti-takeover effects. Rights issued
under the plan will cause substantial dilution to a person or group that
attempts to acquire the Company on terms not approved by the Company's Board
of Directors. See "Certain Anti-Takeover Effects of Certain Provisions of the
Certificate of Incorporation, the Bylaws and State Law" and "Stockholder
Rights Plan."
 
UNCERTAINTY OF FUTURE PROFITABILITY
 
  As a subsidiary of Electronics, Sensors & Systems was profitable in fiscal
1994 and 1996, but sustained an operating loss in fiscal 1995. The Company's
ability to increase revenues and sustain profitability will be largely
dependent on the market acceptance of products currently under development as
well as the successful implementation of the Company's business and marketing
strategy. There can be no assurance that the Company will be able to sustain
or increase sales or sustain profitability. See "Selected Historical and Pro
Forma Financial Data" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
UNCERTAINTY OF DIVIDENDS
 
  No assurance can be given that the Company's Board of Directors will in the
future authorize the payment of dividends.

CLASSIFIED BOARD OF DIRECTORS
 
  The Company has a classified Board of Directors, which may have the effect
of deterring hostile takeovers or delaying changes in control of management of
the Company. For purposes of determining their term of office, directors are
divided into three classes, with the term of office of the first class to
expire at the 1998 annual meeting of stockholders, and the term of office of
the second class to expire at the 1999 annual meeting of stockholders and the
term of office of the third class to expire at the 2000 annual meeting of
stockholders. Class I consists of Mr. Brown and Mr. Crocker; Class II consists
of Mr. Giroir, Dr. Madni and Mr. Wrench; and Class III consists of Mr. Brooks,
Dr. Howard and Dr. Mehrabian. Directors elected to succeed those directors
whose terms expire will be elected to a three year term of office. All
directors hold office until the next annual meeting of stockholders at which
their terms expire and until their successors have been duly elected and
qualified. Executive officers serve at the discretion of the Board. There are
no family relationships among any of the officers and directors.
 
BOARD COMPENSATION AND BENEFITS
 
  Each non-employee director of the Company will receive a monthly fee of
$1,000. Each non-employee director of the Company will also receive a fee of
$500 for each Board or committee meeting attended and a fee of $250 for each
telephone conference Board meeting in which such director participated. The
members of the Board of Directors will also be eligible for reimbursement for
their expenses incurred in connection with attendance at Board meetings in
accordance with Company policy.
 
COMMITTEES OF THE BOARD OF DIRECTORS
 
  Technologies will establish Audit and Compensation Committees of the Board.
Members of the Audit and Compensation Committees will not be employees of
Technologies.
 
  Audit Committee. The Audit Committee will meet with the Company's
independent accountants at least annually to review the results of the annual
audit and to discuss the financial statements; will recommend to the Board the
independent accountants to be retained; will receive and consider the
accountants' comments as to controls, adequacy of staff and management
performance and procedures in connection with audit and financial controls;
and will periodically review the results of the Company's internal audit
program and responses by management. The Audit Committee will be composed of
four directors: Mr. Brooks, who will be the Chairman of the Committee,
Mr. Giroir, Dr. Howard and Dr. Mehrabian.
 
  Compensation Committee. The Compensation Committee will make recommendations

(1) As permitted by rules promulgated by the Commission, no amounts are shown
    for "Other Annual Compensation" because no Named Executive Officer
    received "perquisites" in an amount exceeding the lesser of 10 % of annual
    salary plus bonus or $50,000.
 
(2) Includes annual cash payments designated as automobile allowances, which
    did not exceed $11,400 for any individual in any year; also includes
    amounts earned but deferred at the election of the Named Executive Officer
    pursuant to Electronics' Retirement Savings Plan.
 
(3) Represents the dollar value of shares awarded, calculated by multiplying
    the market value based on the closing sales price on the date of grant by
    the number of shares awarded. At September 28, 1996, the aggregate
    holdings and value (based on the closing sales price at fiscal year-end
    1996 of Electronics' Common Stock as reported on the Nasdaq National
    Market multiplied by the number of shares held) of restricted stock of the
    Named Executive Officers was as follows: Mr. Wrench, 18,419 shares, valued
    at $202,609; Dr. Madni, 32,267 shares, valued at $354,937; Dr. Wan, 14,250
    shares, valued at $156,750; Mr. Corr, 9,700 shares, valued at $106,700.
    The restrictions on awards of restricted stock lapse with respect to 15%
    of the total number of shares per year on the first, second, third, fourth
    and fifth anniversaries of the date of grant and with respect to the
    remaining shares subject to such award on the sixth anniversary of the
    date of grant. Dividends are paid on shares of restricted stock when, as
    and if the Electronics' Board of Directors declares dividends on the
    Common Stock of Electronics.
 
(4) During fiscal 1996, Electronics did not grant any stock options
    or issue any stock appreciation rights to any Named Executive Officer.
 
(5) Includes $2,078, $3,000, $2,999, $3,164 and $2,988 paid in fiscal 1996 to
    Messrs. Crocker, Wrench, Madni, Wan and Corr, respectively, and $2,150,

   $2,790 and $2,471 paid in fiscal 1994 to Messrs. Crocker, Wrench, Wan and
   Corr, respectively, as a normal contribution pursuant to Electronics'
   Retirement Savings Plan. The remaining sum for each Named Executive Officer
   is attributable to premiums paid by Electronics for group term life
   insurance.
 
ELECTRONICS STOCK OPTION GRANTS AND EXERCISES
 
  Electronics granted options to its executive officers and key employees
under its Amended 1987 Incentive Stock Option Plan (the "Plan"). As of June

EMPLOYMENT AGREEMENTS
 
  The employment agreement between Electronics and Mr. Wrench, Senior Vice
President, Chief Financial Officer and a director of the Company, will be
assumed by Technologies. The employment agreement provides that if Mr. Wrench
is terminated by the Company, or a change in control occurs, he will receive
from the Company his then full-time current salary for twelve months after
such termination.
 
  The employment agreement between Electronics and Dr. Madni, President of
Sensors & Systems, will be assumed by Technologies. The employment agreement
renews annually on the anniversary date of the agreement. The agreement
provides that if the Company terminates Dr. Madni without cause or a change in
control of the Company occurs and Dr. Madni executes a general release of
liability, he will receive from the Company his then current full-time salary
and medical, dental and life insurance benefits for the 12 months following
the termination or change of control, his annual bonus prorated to the date of
termination or change in control and an amount equal to the average of the
bonuses paid Dr. Madni over the prior three completed fiscal years, including,
as applicable, bonuses paid by Electronics.
 
  The Company will enter into Executive Change in Control Benefit Agreements
with each of the Named Executive Officers. Under such an agreement, an
executive will receive a lump sum severance payment of one year's base pay
plus the average annual bonus over the preceding three fiscal years
(including, if applicable, prior service with Electronics) if the executive's
employment with the Company terminates voluntarily or involuntarily within
twelve months following a change in control of the Company, as defined in the
agreement, unless the termination is for cause, as defined in the agreement.
The Company will also pay for the executive's
 
                                      38
<PAGE>
 
and his/her dependents' health coverage for up to eighteen months following a
termination of employment for which the executive received a severance payment
under the agreement.
 
                 NEW INCENTIVE PLANS OF BEI TECHNOLOGIES, INC.
 
1997 EQUITY INCENTIVE PLAN
   
  The Company's 1997 Equity Incentive Plan (the "Incentive Plan") was adopted
by the Board of Directors in September 1997. The Incentive Plan provides for
the grant or issuance of incentive stock options to employees and nonstatutory
stock options, restricted stock purchase awards, and stock bonuses to
consultants, employees and directors (collectively, "Stock Awards"). A total
of 1,600,000 shares of common stock is available for stock awards under the
Incentive Plan. To date no options, awards or bonuses have been granted under
the Incentive Plan. Incentive stock options granted under the Incentive Plan
are intended to qualify as "incentive stock options" within the meaning of
Section 422 of the Code.     
 
  The Incentive Plan is administered by the Compensation Committee of the
Board of Directors which, in the case of stock options, determines optionees
and the terms of options granted, including the exercise price, the number of
shares subject to the option and the exercisability thereof.
   
  The terms of options granted under the Incentive Plan may not exceed ten
years from the date of grant. It is anticipated that shares covered by options
under the Incentive Plan will typically vest at the rate of 33% on the first
anniversary of the vesting start date, 33% on the second anniversary of the
vesting start date and 34% on the third anniversary of the vesting start date,
although shares may be subject to different vesting terms. No Stock Award
(including restricted stock purchase awards and stock bonuses for as long as
they remain subject to the agreements pursuant to which they were awarded) may
be transferred by the holder other than by will or the laws of descent or
distribution or (except for incentive stock options) pursuant to a "qualified
domestic relations order." An optionee whose relationship with the Company or
any of its subsidiaries ceases for any reason (other than by death or
permanent and total disability) may exercise options in the three-month period
following such cessation (unless such options terminate or expire sooner by
their terms) or in such shorter or longer period determined by the Board of
Directors.     
 
  Shares subject to Stock Awards granted under the Incentive Plan that have
lapsed or terminated may again be subject to Stock Awards granted under the
Plan. The Board of Directors has the authority to effect, with the consent of
affected holders, the cancellation of outstanding Stock Awards in return for
the grant of new Stock Awards for the same or a different number of Stock
Awards with an exercise price per share of 85%, 100% or, under certain
circumstances, 110% of fair market value of the Company Common Stock on the
new grant date, with the shares subject to the outstanding Stock Awards being
canceled again becoming available for grant under the Incentive Plan.
 
  In the event of a dissolution or liquidation of the Company, specified type
of merger or other corporate reorganization, to the extent permitted by law,
all outstanding Stock Awards will either be assumed by the surviving entity or
continue in full force and effect. In the event that the surviving entity
declines to assume or substitute similar awards, then the time during which
such Stock Awards may be exercised will be accelerated and the Awards
terminated if not exercised prior to the event. The acceleration of a Stock
Award in the event of an acquisition or similar corporate event may be viewed
as an anti-takeover provision, which may have the effect of discouraging a
proposal to acquire or otherwise to obtain control of the Company.
 
  The Incentive Plan will terminate on September 10, 2007 unless sooner
terminated by the Board of Directors.
   
  See "The Distribution--Other Consequences of the Distribution--Stock
Options" for information regarding the conversion of outstanding options to
purchase Electronics Common Stock into options to purchase Technologies Common
Stock and "The Distribution--Other Consequences of the Distribution--Restated
Stock" for information regarding the issuance of shares of restricted stock of
Technologies to holders of restricted stock of Electronics.

<PAGE>
  
401(K) PLAN
   
  The Company will adopt a tax qualified employee savings and retirement plan
(the "401(k) Plan") under which eligible employees may elect to defer their
current compensation by up to certain statutorily prescribed annual limits
($9,500 in 1997) and to contribute such amount to the 401(k) Plan. The 401(k)
Plan will permit, but not require, additional matching contributions to the
401(k) Plan by the Company on behalf of all participants in the 401(k) Plan.
The 401(k) Plan is intended to qualify under Section 401 of the Code, so that
contributions by employees or by the Company to the 401(k) Plan, and income
earned on the 401(k) Plan contributions, are not taxable to employees until
withdrawn from the 401(k) Plan, and so that contributions by the Company, if
any, will be deductible by the Company when made. The trustee under the 401(k)
Plan, at the direction of each participant, will invest the 401(k) Plan
employee salary deferrals in selected investment options.     
 
MANAGEMENT INCENTIVE BONUS PLAN
 
  Technologies' Board of Directors intends to adopt a Management Incentive
Bonus Plan for fiscal 1998 ("MIB Plan") covering employees of Technologies,
including Sensors & Systems. On the basis of goals relating to return on
equity, and subject to predetermined limits under the MIB Plan, the
Technologies Compensation Committee will in its discretion determine a bonus
fund for each company following the end of the year. Based upon
recommendations from management of each company, the Compensation Committee
may in its discretion approve individual awards to employees of the respective
companies, subject to final approval of the Technologies Board of Directors.
 
  Electronics has had management incentive bonus plans in place for over 8
years. Incentive awards totalling approximately $608,250 were made with
respect to fiscal year 1996. The amounts of such incentive payments to Messrs.
Crocker, Wrench and Corr and to Drs. Madni and Wan are included in the
"Summary Compensation Table" under "Compensation of Executive Officers--
Executive Compensation Prior to the Distribution."
 
            LIABILITY AND INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
ELIMINATION OF LIABILITY OF DIRECTORS
 
  The Certificate of Incorporation of the Company (the "Certificate") provides
that a director of the Company will not be personally liable to the Company or
its stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability (i) for any breach of the director's duty of
loyalty to the Company or its stockholders, (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the Delaware Law, which concerns unlawful
payments of dividends, stock purchases or redemptions, or (iv) for any
transaction from which the director derived an improper personal benefit. If
the Delaware Law is amended to authorize corporate action further eliminating
or limiting the personal liability of directors, then the liability of a
director of the Company shall be eliminated or limited to the fullest extent
permitted by the Delaware Law, as so amended from time to time.
 
  While the Certificate provides directors with protection from awards for
monetary damages for breaches of their duty of care, it does not eliminate
such duty. Accordingly, the Certificate will have no effect on the
availability of equitable remedies such as an injunction or rescission based
on a director's breach of his or her duty of care. The provisions of the
Certificate described above apply to an officer of the Company only if he or
she is a director of the Company and is acting in his or her capacity as
director, and do not apply to officers of the Company who are not directors.
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  The Company's Bylaws (the "Bylaws") provide that the Company will indemnify
its directors and executive officers and may indemnify its other officers,
employees and other agents to the extent not prohibited
 
                                      40
<PAGE>
 
by the Delaware Law. Under the Bylaws, indemnified parties are entitled to
indemnification to the fullest extent permitted by law. The Bylaws also
require the Company to advance litigation expenses in the case of stockholder
derivative actions or other actions, against an undertaking by the indemnified
party to repay such advances if it is ultimately determined that the
indemnified party is not entitled to indemnification.
 
               OWNERSHIP OF TECHNOLOGIES COMMON STOCK BY CERTAIN
                       BENEFICIAL OWNERS AND MANAGEMENT
 
  The following table sets forth the number of shares of Company Common Stock
expected to be owned following the Distribution, directly or indirectly by:
(i) each director; (ii) each of the Named Executive Officers; (iii) all
executive officers and directors of the Company as a group; and (iv) all those
known by the Company to be beneficial owners of more than five percent of its
Common Stock, based on the ownership by such persons of Electronics Common
Stock as of August 1, 1997. The ownership information presented below assumes

 (1) This table is based upon information supplied by officers, directors and
     principal stockholders of the Company and upon any Schedules 13D or 13G
     filed with the SEC. Unless otherwise indicated in the footnotes to this
     table and subject to community property laws where applicable, the
     Company believes that each of the stockholders named in this table has
     sole voting and investment power with respect to the shares indicated as
     beneficially owned.
 
 (2) Applicable percentages are based on 7,025,843 shares outstanding on
     August 1, 1997, adjusted as required by rules promulgated by the SEC.
     Outstanding shares do not include 934,424 shares held as Treasury Stock
     as of August 1, 1997.
 
 (3) Includes 400,000 shares held by Charles Crocker as trustee for his adult
     children, as to which Mr. Crocker disclaims beneficial ownership. Also

                         DESCRIPTION OF CAPITAL STOCK
 
AUTHORIZED CAPITAL STOCK
   
  The Company's authorized capital stock consists of 2,000,000 shares of
preferred stock, par value $.001 per share (the "Company Preferred Stock"),
and 20,000,000 shares of Company Common Stock. No shares of Company Preferred
Stock will be issued in connection with the Distribution. Based on the number
of shares of Electronics Common Stock outstanding at September 22 , 1997,
approximately 7,115,000 shares of Company Common Stock will be issued to the
stockholders of Electronics in the Distribution. All of the shares of Company
Common Stock issued in the Distribution will be validly issued, fully paid and
nonassessable.     
 
COMPANY COMMON STOCK
 
  The holders of Company Common Stock will be entitled to one vote for each
share on all matters voted on by stockholders, including elections of
directors, and, except as otherwise required by law or provided in any
resolution adopted by the Board with respect to any series of Company
Preferred Stock, the holders of such shares exclusively will possess all
voting power. The Certificate of Incorporation of the Company does not provide
for cumulative voting in the election of directors. Thus, under the Delaware
Law, the holders of more than one-half of the outstanding Company Common Stock
generally will be able to elect all of the directors of the Company then
standing for election. Subject to any preferential rights of any outstanding
series of Company Preferred Stock created by the Board from time to time, the
holders of Company Common Stock will be entitled to such dividends as may be
declared from time to time by the Board from funds available therefor, and
upon liquidation will be entitled to receive pro rata all assets of the
Company available for distribution to such holders.
 
COMPANY PREFERRED STOCK
 
  Under the Certificate, the Board will be authorized to provide for the issue
of shares of Company Preferred Stock, in one or more series, and to fix for
each such series such powers, designations, preferences and relative,
participating, optional and other special rights, and such qualifications,
limitations or restrictions, as are stated in the resolution adopted by the
Board providing for the issue of such series and as are permitted by the
Delaware Law. See "Certain Anti-takeover Effects of Certain Provisions of the
Certificate of Incorporation, the Bylaws and State Law--Preferred Stock" and
"Stockholder Rights Plan."
 
COMMON STOCK DIVIDEND POLICY
 
  The payment and amount of cash dividends on the Common Stock after the
Distribution will be subject to the discretion of the Company's Board of
Directors.
 
              CERTAIN ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS
                     OF THE CERTIFICATE OF INCORPORATION,
                           THE BYLAWS AND STATE LAW
 
  The Certificate and the Bylaws of the Company contain certain provisions
that could make more difficult the acquisition of the Company by means of a
tender offer, a proxy contest or otherwise. The description set forth below is
intended as a summary only and is qualified in its entirety by reference to
the Certificate and the Bylaws.
 
CLASSIFIED BOARD OF DIRECTORS
   
  The Certificate and Bylaws provide that the Board will be divided into three
classes of directors, with the classes to be as nearly equal in number as
possible. The Board consists of the persons referred to under "Directors and
Executive Officers of the Company" above. The Certificate and the Bylaws
provide that, of the initial directors of the Company, approximately one-third
will continue to serve until the 1998 annual meeting     
 
                                      43
<PAGE>
 
   
of stockholders, approximately one-third will continue to serve until the 1999
annual meeting of stockholders, and approximately one-third will continue to
serve until the 2000 annual meeting of stockholders. Of the initial directors,
Mr. Brown and Mr. Crocker will serve until the 1998 annual meeting of
stockholders, Mr. Giroir, Dr. Madni and Mr. Wrench will serve until the 1999
annual meeting of stockholders and Mr. Brooks, Dr. Howard and Dr. Mehrabian
will serve until the 2000 annual meeting of stockholders. Starting with the
1998 annual meeting of stockholders, one class of directors will be elected
each year for a three-year term.     
 
  The classification of directors will have the effect of making it more
difficult for stockholders to change the composition of the Board. At least
two annual meetings of stockholders, instead of one, will generally be
required to effect a change in a majority of the Board. Such a delay may help
ensure that the Company's directors, if confronted by a holder attempting to
force a proxy contest, a tender or exchange offer, or an extraordinary
corporate transaction, would have sufficient time to review the proposal as
well as any available alternatives to the proposal and to act in what they
believe to be the best interest of the stockholders. The classification
provisions will apply to every election of directors, however, regardless of
whether a change in the composition of the Board would be beneficial to the
Company and its stockholders and whether or not a majority of the Company's
stockholders believe that such a change would be desirable.
 
  The classification provisions could also have the effect of discouraging a
third party from initiating a proxy contest, making a tender offer or
otherwise attempting to obtain control of the Company, even though such an
attempt might be beneficial to the Company and its stockholders. The
classification of the Board could thus increase the likelihood that incumbent
directors will retain their positions. In addition, because the classification
provisions may discourage accumulations of large blocks of the Company's stock
by purchasers whose objective is to take control of the Company and remove a
majority of the Board, the classification of the Board could tend to reduce
the likelihood of fluctuations in the market price of the Company Common Stock
that might result from accumulations of large blocks for such a purpose.
Accordingly, stockholders could be deprived of certain opportunities to sell
their shares of Company Common Stock at a higher market price than might
otherwise be the case.
 
NUMBER OF DIRECTORS; REMOVAL; FILLING VACANCIES
 
  The Certificate provides that, subject to any rights of holders of Company
Preferred Stock to elect additional directors under specified circumstances,
the number of directors will be fixed from time to time exclusively pursuant
to a resolution adopted by the Board. In addition, the Bylaws provide that,
unless the Board otherwise determines, any vacancies will be filled only by
the affirmative vote of a majority of the remaining directors, though less
than a quorum. Accordingly, the Board could prevent any stockholder from
enlarging the Board and filling the new directorships with such stockholder's
own nominees.
 
  Under the Delaware Law, unless otherwise provided in the Certificate,
directors serving on a classified board may only be removed by the
stockholders for cause. In addition, the Certificate and the Bylaws provide
that directors may be removed only for cause and only upon the affirmative
vote of holders of at least 80% of the voting power of all the then
outstanding shares of stock entitled to vote generally in the election of
directors ("Voting Stock"), voting together as a single class.
 
NO STOCKHOLDER ACTION BY WRITTEN CONSENT; SPECIAL MEETINGS
   
  The Certificate and the Bylaws provide that stockholder action can be taken
only at an annual or special meeting of stockholders and prohibit stockholder
action by written consent in lieu of a meeting. The Bylaws provide that
special meetings of stockholders can be called by a majority of the Board or
by resolution of the Board. Stockholders are not permitted to call a special
meeting of stockholders or to require that the Board call a special meeting.
Moreover, the business permitted to be conducted at any special meeting of
stockholders is limited to the business brought before the meeting pursuant to
the notice of meeting given by the Company.     
 
  The provisions of the Certificate and the Bylaws prohibiting stockholder
action by written consent may have the effect of delaying consideration of a
stockholder proposal until the next annual meeting unless a special
 
                                      44
<PAGE>
 
   
meeting is called at the request of a majority of the Board. These provisions
would also prevent the holders of a majority of the Voting Stock from
unilaterally using the written consent procedure to take stockholder action
and from taking action by written consent. Moreover, a stockholder could not
force stockholder consideration of a proposal over the opposition of the Board
by calling a special meeting of stockholders prior to the time a majority of
the Board believes such consideration to be appropriate.     
 
ADVANCE NOTICE PROVISIONS FOR STOCKHOLDER NOMINATIONS AND STOCKHOLDER
PROPOSALS
 
  The Bylaws establish an advance notice procedure for stockholders to make
nominations of candidates for election as directors, or bring other business
before an annual meeting of stockholders of the Company (the "Stockholder
Notice Procedure").
 
  The Stockholder Notice Procedure provides that only persons who are
nominated by, or at the direction of, the Board, or by a stockholder who has
given timely written notice to the Secretary of the Company prior to the
meeting at which directors are to be elected, will be eligible for election as
directors of the Company. The Stockholder Notice Procedure provides that at an
annual meeting only such business may be conducted as has been brought before
the meeting by, or at the direction of, the Board or by a stockholder who has
given timely written notice to the Secretary of the Company of such
stockholder's intention to bring such business before such meeting. Under the
Stockholder Notice Procedure, for notice of stockholder nominations to be made
at an annual meeting to be timely, such notice must be received by the Company
not less than 60 days nor more than 90 days prior to the first anniversary of
the previous year's annual meeting (or if no annual meeting was held in the
previous year or the date of the annual meeting is changed by more than 30
days from the date contemplated in the previous years' proxy statement, not
earlier than the 90th day prior to such meeting and not later than the later
of (x) the 60th day prior to such meeting and (y) the 10th day after public
announcement of the date of such meeting is first made, if public announcement
of such meeting was made less than 10 days prior to the date of such meeting).
 
  Under the Stockholder Notice Procedure, a stockholder's notice to the
Company proposing to nominate a person for election as a director must contain
certain information, including, without limitation, the name, age, business
address and residence address of such nominee, the principal occupation or
employment of the nominee, the class and number of shares of the corporation
which are beneficially owned by the nominee, a description of all arrangements
or understandings between the stockholder and each nominee and any other
person or persons (naming such person or persons) pursuant to which the
nominations are to be made by the stockholder, the identity and address, as
they appear on the Company's books, of the nominating stockholder, the class
and number of shares of stock of the Company which are beneficially owned by
such stockholder, and all information regarding the proposed nominee that
would be required to be included in a proxy statement soliciting proxies for
the proposed nominee.
   
  Under the Stockholder Notice Procedure, a stockholder's notice relating to
the conduct of business other than the nomination of directors must contain
certain information about such business and about the proposing stockholder,
including, without limitation, a brief description of the business the
stockholder proposes to bring before the meeting, the reasons for conducting
such business at such meeting, the name and address of such stockholder, the
class and number of shares of stock of the Company beneficially owned by such
stockholder, any material interest of such stockholder in the business so
proposed, and any other information required to be provided by the stockholder
pursuant to Regulation 14A under the Exchange Act in his capacity as a
proponent to a stockholder proposal. If the chairman of the meeting determines
that a person was not nominated, or other business was not brought before the
meeting, in accordance with the Stockholder Notice Procedure, such person will
not be eligible for election as a director, or such business will not be
conducted at such meeting, as the case may be.     
 
  By requiring advance notice of nominations by stockholders, the Stockholder
Notice Procedure will afford the Board an opportunity to consider the
qualifications of the proposed nominees and, to the extent deemed necessary or
desirable by the Board, to inform stockholders about such qualifications. By
requiring advance
 
                                      45
<PAGE>
 
notice of other proposed business, the Stockholder Notice Procedure will also
provide a more orderly procedure for conducting annual meetings of
stockholders and, to the extent deemed necessary or desirable by the Board,
will provide the Board with an opportunity to inform stockholders, prior to
such meetings, of any business proposed to be conducted at such meetings,
together with any recommendations as to the Board's position regarding action
to be taken with respect to such business, so that stockholders can better
decide whether to attend such a meeting or to grant a proxy regarding the
disposition of any such business.
 
  Although the Bylaws do not give the Board any power to approve or disapprove
stockholder nominations for the election of directors or proposals for action,
they may have the effect of precluding a contest for the election of directors
or the consideration of stockholder proposals if the proper procedures are not
followed, and of discouraging or deterring a third party from conducting a
solicitation of proxies to elect its own slate of directors or to approve its
own proposal, without regard to whether consideration of such nominees or
proposals might be harmful or beneficial to the Company and its stockholders.
 
PREFERRED STOCK
   
  The Certificate authorizes the Board to establish one or more series of
Company Preferred Stock and to determine, with respect to any series of
Company Preferred Stock, the terms and rights of such series, including
(i) the designation of the series, (ii) the number of shares of the series,
which number the Board may thereafter (except where otherwise provided in the
Preferred Stock designation) increase or decrease (but not below the number of
shares thereof then outstanding), (iii) whether dividends, if any, will be
cumulative or noncumulative and the dividend rate of the series, (iv) the
dates at which dividends, if any, will be payable, (v) the redemption rights
and price or prices, if any, for shares of the series, (vi) the terms and
amounts of any sinking fund provided for the purchase or redemption of shares
of the series, (vii) the amounts payable on shares of the series in the event
of any voluntary or involuntary liquidation, dissolution or winding up of the
affairs of the Company, (viii) whether the shares of the series will be
convertible into shares of any other class or series, or any other security,
of the Company or any other corporation, and, if so, the specification of such
other class or series or such other security, the conversion price or prices
or rate or rates, any adjustments thereof, the date or dates as of which such
shares shall be convertible and all other terms and conditions upon which such
conversion may be made, (ix) restrictions on the issuance of shares of the
same series or of any other class or series, and (x) the voting rights, if
any, of the holders of such series.     
 
  The Company believes that the ability of the Board to issue one or more
series of Company Preferred Stock will provide the Company with flexibility in
structuring possible future financings and acquisitions, and in meeting other
corporate needs which might arise. The authorized shares of Company Preferred
Stock, as well as shares of Company Common Stock, will be available for
issuance without further action by the Company's stockholders, unless such
action is required by applicable law or the rules of any stock exchange or
automated quotation system on which the Company's securities may be listed or
traded. The Nasdaq currently requires stockholder approval as a prerequisite
to listing shares in several instances, including where the present or
potential issuance of shares could result in an increase in the number of
shares of common stock, or in the amount of voting securities, outstanding of
at least 20%. If the approval of the Company's stockholders is not required
for the issuance of shares of Company Preferred Stock or Company Common Stock,
the Board may determine not to seek stockholder approval.
 
  Although the Board has no intention at the present time of doing so, it
could issue a series of Company Preferred Stock that could, depending on the
terms of such series, impede the completion of a merger, tender offer or other
takeover attempt. The Board will make any determination to issue such shares
based on its judgment as to the best interests of the Company and its
stockholders. The Board, in so acting, could issue Company Preferred Stock
having terms that could discourage an acquisition attempt through which an
acquiror may be able to change the composition of the Board, including a
tender offer or other transaction that some, or a majority, of the Company's
stockholders might believe to be in their best interests or in which
stockholders might receive a premium for their stock over the then current
market price of such stock. See "Stockholder Rights Plan" below.
 
                                      46
<PAGE>
 
AMENDMENT OF CERTAIN PROVISIONS OF THE CERTIFICATE AND BYLAWS
   
  Under the Delaware Law, the stockholders have the right to adopt, amend or
repeal the bylaws and, with the approval of the board of directors, the
certificate of incorporation of a corporation. In addition, the Bylaws may be
adopted, amended or repealed by the board of directors. The Certificate
provides that the affirmative vote of the holders of at least 80% of the
voting power of the outstanding shares of Voting Stock, voting together as a
single class, is required to amend provisions of the Certificate relating to
the prohibition of stockholder action without a meeting; the number, election
and term of the Company's directors; the removal of directors; the limitation
of a director's personal liability for breaches of his fiduciary duty in
certain circumstances; the amendment of the Certificate; or the Fair Price
Provision. The vote of the holders of 66 2/3% of the outstanding shares of
Voting Stock is required to amend all other provisions of the Certificate. The
Certificate further provides that the Bylaws may be amended by the Board or by
the affirmative vote of the holders of at least a majority of the voting power
of the outstanding shares of Voting Stock, voting together as a single class,
although any amendment by the stockholders to the provisions of the Bylaws
related to annual and special meetings of stockholders, the prohibition on
stockholder action by written consent in lieu of a meeting, the size and
powers of the Board, the classification of the Board, filling of Board
vacancies and the removal of Board members, the indemnification of Board
members and officers against liabilities incurred in connection with the
performance of their duties, and amendment of the Bylaws, requires the
affirmative vote of the holders of at least 80% of the outstanding Voting
Stock. These 80% voting requirements will have the effect of making more
difficult any amendment by stockholders of the Bylaws or of any of the
provisions of the Certificate described above, even if a majority of the
Company's stockholders believe that such amendment would be in their best
interests.     
 
ANTI-TAKEOVER LEGISLATION
 
  Section 203 of the Delaware Law provides that, subject to certain exceptions
specified therein, a corporation shall not engage in any business combination
with any "interested stockholder" for a three-year period following the date
that such stockholder becomes an interested stockholder unless (i) prior to
such date, the board of directors of the corporation approved either the
business combination or the transaction which resulted in the stockholder
becoming an interested stockholder, (ii) upon consummation of the transaction
which resulted in the stockholder becoming an interested stockholder, the
interested stockholder owned at least 85% of the voting stock of the
corporation outstanding at the time the transaction commenced (excluding
certain shares), or (iii) on or subsequent to such date, the business
combination is approved by the board of directors of the corporation and by
the affirmative vote of at least 66 2/3% of the outstanding voting stock which
is not owned by the interested stockholder. Except as specified in Section 203
of the Delaware Law, an interested stockholder is defined to include (x) any
person that is the owner of 15% or more of the outstanding voting stock of the
corporation, or is an affiliate or associate of the corporation and was the
owner of 15% or more of the outstanding voting stock of the corporation, at
any time within three years immediately prior to the relevant date and (y) the
affiliates and associates of any such person.
 
FAIR PRICE PROVISION
   
  The Certificate contains a provision (the "Fair Price Provision") that
requires the approval of the holders of 80% of the Company's Voting Stock,
voting as a single class, as a condition to a merger or certain other business
transactions (a "business combination") between the Company and a holder of
more than 10% of the Company's voting power and certain assignees of such 10%
holders (an "interested stockholder"), except in cases where the disinterested
directors approve the transaction or certain minimum price criteria and other
procedural requirements are met. The minimum price criteria are complex, but
generally require that in a transaction in which stockholders are to receive
payments, holders of Common Stock must receive a value equal to the highest
price paid by the interested stockholder for Common Stock (i) during the two
years prior to the date of announcement of the business combination, or (ii)
if the interested stockholder becomes an interested stockholder more than two
years prior to the date of announcement of the business combination, in the
transaction in which it became an interested stockholder, whichever is higher,
and that such payment be made in cash or in the type of consideration paid by
the interested stockholder for the greatest portion of its shares. Any     
 
                                      47
<PAGE>
 
solicitation of stockholder approval of a transaction subject to the Fair
Price Provision must be pursuant to a proxy statement meeting the requirements
of the proxy rules under the Exchange Act.
 
  The Fair Price Provision is intended to provide some protection against
certain forms of two-tiered corporate takeovers in which the acquiror seeks as
a first step to acquire a controlling equity interest in a company and then as
a second step to acquire the remaining equity interest with cash or securities
that have a value substantially below the consideration paid to acquire
control. The Company's Board of Directors believes that the Fair Price
Provision will help assure that all the Company's stockholders will be treated
similarly if certain kinds of business combinations are effected. However, the
Fair Price Provision may make it more difficult to accomplish certain
transactions that are opposed by the incumbent Board of Directors and that
could be beneficial to stockholders.
 
COMPARISON WITH CERTAIN RIGHTS OF HOLDERS OF ELECTRONICS COMMON STOCK
   
  The Company's Certificate of Incorporation requires the affirmative vote of
the holders of at least 80% of the outstanding Voting Stock to amend
provisions in the Certificate of Incorporation providing for the determination
of the number of directors, the existence of a classified Board of Directors,
the removal of a director from office, the filling of vacancies on the Board
of Directors, the inability of stockholders to act by written consent, the
elimination of director liability in certain circumstances, a fair price
provision and the amendment of the Certificate of Incorporation. The
Electronic's Restated Certificate of Incorporation requires the affirmative
vote of the holders of at least 66 2/3% of the outstanding voting shares to
amend provisions in the Certificate of Incorporation providing for the
determination of the number of directors, the existence of a classified Board
of Directors, the removal of a director from office, the filling of vacancies
on the Board of Directors, a fair price provision and the amendment of the
Restated Certificate of Incorporation.     
   
  The Company's Certificate of Incorporation provides for the amendment of
selected provisions of the Company's Bylaws with the affirmative vote of the
holders of at least 80% of the Company's outstanding voting shares and of the
balance of the Bylaw provisions with the vote of the holders of at least 66
2/3% of the voting shares. Electronics' Bylaws provides for the amendment of
the Bylaws by the stockholders on terms similar to those contained in the
Company's Certificate of Incorporation. Both the Company's Certificate of
Incorporation and Electronic's Restated Certificate of Incorporation provide
for the amendment of each company's Bylaws by the respective Board of
Directors.     
   
  The Company's fair price provision contained in its Certificate of
Incorporation requires the affirmative vote of the holders of at least 80% of
the outstanding shares of the Company's Voting Stock to approve specified
forms of business combinations entered into by the Company. The fair price
provision contained in the Restated Certificate of Incorporation of
Electronics requires the affirmative vote of the holders of at least 66 2/3%
of the outstanding shares of Electronic's voting stock to approve similar
forms of business combinations entered into by Electronics.     
   
  The Restated Certificate of Incorporation of Electronics allows for the
removal of a director from office with the affirmative vote of the holders of
a majority of the voting stock if the removal is for cause, and with the
affirmative vote of the holders of 66 2/3% of the outstanding shares of voting
stock of the removal is without cause. The Certificate of Incorporation of the
Company only provides for the removal of directors with cause, and only with
the affirmative vote of the holders of 80% of the outstanding shares of voting
stock.     
 
  The Restated Certificate of Incorporation of Electronic's allows the
stockholders to fill newly created directorships or vacancies on the Board of
Directors with an affirmative vote of the holders of a majority of the
outstanding shares of voting stock. Unless otherwise determined by resolution
of the Board of Directors, the Company's Certificate of Incorporation provides
for the filling of newly created directorships and vacancies on the Board of
Directors by the affirmative vote of a majority of the directors.

  Electronics' charter documents are substantially similar to the Company's
Certificate and Bylaws with respect to (i) the elimination of directors'
liabilities in certain circumstances, (ii) determining the size of the board
of directors and the directors' terms of office, (iii) a fair price provision
and (iv) the application of Section 203 of the Delaware Law.
 
                            STOCKHOLDER RIGHTS PLAN
   
  In September, 1997 the Board of Directors of the Company approved the
adoption of a Stockholder Rights Plan (the "Plan"). The terms of the Plan
provide for a dividend distribution of one preferred share purchase right (a
"Right") for each outstanding share of common stock, par value $.001 per share
(the "Common Shares"), of the Company. The dividend is payable on September
29, 1997 to the stockholders of record on that date (the "Rights Record
Date"). Each Right entitles the registered holder to purchase from the Company
one one-hundredth of a share of Series A Junior Participating Preferred Stock,
par value $.001 per share (the "Preferred Shares"), at a price of $70 per one
one-hundredth of a Preferred Share (the "Purchase Price"), subject to
adjustment. Each one one-hundredth of a share of the Preferred Shares has
designations and powers, preferences and rights, and the qualifications,
limitations and restrictions which make its value approximately equal to the
value of a Common Share. The description and terms of the Rights are set forth
in a Rights Agreement (the "Rights Agreement"), dated as of September 11, 1997
entered into between the Company and ChaseMellon Shareholder Services, L.L.C.
as rights agent (the "Rights Agent").     
   
  Initially, the Rights will be evidenced by the stock certificates
representing the Common Shares outstanding from time to time, and no separate
Right Certificates, as defined below, will be distributed. Until the earlier
to occur of (i) the date of a public announcement that a person, entity or
group of affiliated or associated persons have acquired beneficial ownership
of 15% or more of the outstanding Common Shares (an "Acquiring Person") or
(ii) 10 business days (or such later date as may be determined by action of
the Board of Directors prior to such time as any person or entity becomes an
Acquiring Person) following the commencement of, or announcement of an
intention to commence, a tender offer or exchange offer the consummation of
which would result in any person or entity becoming an Acquiring Person (the
earlier of such dates being called the "Rights Distribution Date"), the Rights
will be evidenced, with respect to any of the Common Share certificates
outstanding as of the Rights Record Date, by such Common Share certificate
with or without a copy of the Summary of Rights, which is included in the
Rights Agreement as Exhibit C thereto (the "Summary of Rights").     
   
  Until the Rights Distribution Date, the Rights will be transferable with and
only with the Common Shares. Until the Rights Distribution Date (or earlier
redemption or expiration of the Rights), new Common Share certificates issued
after the Rights Record Date, upon transfer or new issuance of Common Shares,
will contain a notation incorporating the Rights Agreement by reference. Until
the Rights Distribution Date (or earlier redemption or expiration of the
Rights), the surrender or transfer of any certificates for Common Shares
outstanding as of the Rights Record Date, even without such notation or a copy
of the Summary of Rights being attached thereto, will also constitute the
transfer of the Rights associated with the Common Shares represented by such
certificate. As soon as practicable following the Rights Distribution Date,
separate certificates evidencing the Rights ("Right Certificates") will be
mailed to holders of record of the Common Shares as of the close of business
on the Rights Distribution Date and such separate Right Certificates alone
will evidence the Rights.     
   
  The Rights are not exercisable until the Rights Distribution Date. The
Rights will expire on September 10, 2007 (the "Final Expiration Date"), unless
the Rights are earlier redeemed or exchanged by the Company, in each case, as
described below.     
 
  The Purchase Price payable, and the number of Preferred Shares or other
securities or other property issuable, upon exercise of the Rights are subject
to adjustment from time to time to prevent dilution (i) in the event of a
stock dividend on, or a subdivision, combination or reclassification of, the
Preferred Shares, (ii) upon the grant to holders of the Preferred Shares of
certain rights or warrants to subscribe for or purchase Preferred Shares at a
price, or securities convertible into Preferred Shares with a conversion
price, less than the then current
 
                                      49
<PAGE>
  
market price of the Preferred Shares or (iii) upon the distribution to holders
of the Preferred Shares of evidences of indebtedness or assets (excluding
regular periodic cash dividends paid out of earnings or retained earnings or
dividends payable in Preferred Shares) or of subscription rights or warrants
(other than those referred to above). The exercise of Rights for Preferred
Shares is at all times subject to the availability of a sufficient number of
authorized but unissued Preferred Shares.
 
  The number of outstanding Rights and the number of one one-hundredths of a
Preferred Share issuable upon exercise of each Right are also subject to
adjustment in the event of a stock split of the Common Shares or a stock
dividend on the Common Shares payable in Common Shares or subdivisions,
consolidation or combinations of the Common Shares occurring, in any case,
prior to the Rights Distribution Date.
 
  Preferred Shares purchasable upon exercise of the Rights will not be
redeemable. Each Preferred Share will be entitled to a minimum preferential
quarterly dividend payment of $1.00 but will be entitled to an aggregate
dividend of 100 times the dividend declared per Common Share. In the event of
liquidation, the holders of the Preferred Shares would be entitled to a
minimum preferential liquidation payment of $100 per share, but would be
entitled to receive an aggregate payment equal to 100 times the payment made
per Common Share. Each Preferred Share will have 100 votes, voting together
with the Common Shares. Finally, in the event of any merger, consolidation or
other transaction in which Common Shares are exchanged, each Preferred Share
will be entitled to receive 100 times the amount of consideration received per
Common Share. These rights are protected by customary anti-dilution
provisions. Because of the nature of the Preferred Shares' dividend and
liquidation rights, the value of one one-hundredth of a Preferred Share should
approximate the value of one Common Share. The Preferred Shares would rank
junior to any other series of the Company's preferred stock.
 
  In the event that any person or group of affiliated or associated persons
becomes an Acquiring Person, proper provision shall be made so that each
holder of a Right, other than Rights beneficially owned by the Acquiring
Person and its associates and affiliates (which will thereafter be void), will
for a 60-day period have the right to receive upon exercise that number of
Common Shares having a market value of two times the exercise price of the
Right (or, if such number of shares is not and cannot be authorized, the
Company may issue Preferred Shares, cash, debt, stock or a combination thereof
in exchange for the Rights). This right will terminate 60 days after the date
on which the Rights become nonredeemable (as described below), unless there is
an injunction or similar obstacle to exercise of the Rights, in which event
this right will terminate 60 days after the date on which the Rights again
become exercisable.
 
  Generally, under the Plan, an "Acquiring Person" shall not be deemed to
include (i) the Company, (ii) a subsidiary of the Company, (iii) any employee
benefit or compensation plan of the Company, (iv) any entity holding Common
Shares for or pursuant to the terms of any such employee benefit or
compensation plan, or (v) an Excluded Person which shall mean Mr. Crocker so
long as he and any trust or other fiduciary account for the benefit of Mr.
Crocker or his ancestors, descendents, siblings or spouse (a "Trust")
beneficially own 30% or less of the outstanding Common Shares; provided,
however, that Mr. Crocker and any Trust shall not be an Excluded Person if
such persons beneficially own more than 30% of the outstanding Common Shares
without the prior approval of the Board of Directors of the Company. In
addition, except under limited circumstances, no person or entity shall become
an Acquiring Person as the result of the acquisition of Common Shares by the
Company which, by reducing the number of shares outstanding, increases the
proportionate number of shares beneficially owned by such person or entity to
15% or more of the Common Shares then outstanding.
 
  In the event that the Company is acquired in a merger or other business
combination transaction or 50% or more of its consolidated assets or earning
power are sold to an Acquiring Person, its associates or affiliates or certain
other persons in which such persons have an interest, proper provision will be
made so that each holder of a Right will thereafter have the right to receive,
upon the exercise thereof at the then current exercise price of the Right,
that number of shares of common stock of the acquiring company which at the
time of such transaction will have a market value of two times the exercise
price of the Right.
 
  At any time after an Acquiring Person becomes an Acquiring Person and prior
to the acquisition by such Acquiring Person of 50% or more of the outstanding
Common Shares, the Board of Directors of the Company

 
                                      50
<PAGE>
 
may exchange the Rights (other than Rights owned by such person or group which
have become void), in whole or in part, at an exchange ratio of one Common
Share, or one one-hundredth of a Preferred Share, per Right (or, at the
election of the Company, the Company may issue cash, debt, stock or a
combination thereof in exchange for the Rights), subject to adjustment.
 
  With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price. No fractional Preferred Shares will be issued (other than
fractions which are integral multiples of the number of one one-hundredths of
a Preferred Share issuable upon the exercise of one Right, which may, at the
election of the Company, be evidenced by depositary receipts), and in lieu
thereof, an adjustment in cash will be made based on the market price of the
Preferred Shares on the last trading day prior to the date of exercise.
   
  At any time prior to the earliest of (i) the day of the first public
announcement that a person has become an Acquiring Person or (ii) the Final
Expiration Date, the Board of Directors of the Company may redeem the Rights
in whole, but not in part, at a price of $.001 per Right (the "Redemption
Price"). Following the expiration of the above period, the Rights become
nonredeemable. Immediately upon any redemption of the Rights, the right to
exercise the Rights will terminate and the only right of the holders of Rights
will be to receive the Redemption Price.     
 
  The terms of the Rights may be amended by the Board of Directors of the
Company without the consent of the holders of the Rights, except that from and
after such time as the rights are distributed no such amendment may adversely
affect the interest of the holders of the Rights excluding the interests of an
Acquiring Person.
 
  Until a Right is exercised, the holder thereof, as such, will have no rights
as a stockholder of the Company, including, without limitation, the right to
vote or to receive dividends.
 
  The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire the Company
on terms not approved by the Company's Board of Directors. The Rights should
not interfere with any merger or other business combination approved by the
Board of Directors since the Rights may be amended to permit such acquisition
or redeemed by the Company at $.001 per Right prior to the earliest of (i) the
time that a person or group has acquired beneficial ownership of 15% or more
of the Common Shares or (ii) the final expiration date of the rights.

                        REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
BEI Electronics, Inc.
 
  We have audited the accompanying combined balance sheets of the businesses
to comprise BEI Technologies, Inc. (as described in Note 1 to the combined
financial statements) as of September 28, 1996 and September 30, 1995, and
related combined statements of operations, stockholders' equity and cash flows
for each of the three years in the period ended September 28, 1996. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the combined financial position of BEI Technologies,
Inc. at September 28, 1996 and September 30, 1995, and the combined results of
its operations and its cash flows for each of the three years in the period
ended September 28, 1996 in conformity with generally accepted accounting
principles.

                    NOTES TO COMBINED FINANCIAL STATEMENTS
 
  (Information for the nine months ended June 28, 1997 and June 29, 1996, is
                                  unaudited)
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of Presentation: On June 30, 1997, the Board of Directors of BEI
Electronics, Inc. (Electronics) approved a plan of distribution to holders of
Electronics common stock of one share of common stock of BEI Technologies,
Inc. (Technologies or the Company), a newly formed subsidiary, for each share
of Electronics common stock held (the Distribution). In connection with the
Distribution, Electronics will transfer to Technologies all of the assets,
liabilities and operations of its Sensors & Systems and Defense Systems
business segments. As further described in Note 2, on June 30, 1997, the Board
of Directors of Electronics also approved a formal plan to discontinue the
operations of its Defense Systems segment.
 
  The accompanying combined financial statements of Technologies present the
combined financial position and results of operations of BEI Sensors & Systems
Company, Inc. and Defense Systems Company, Inc., wholly-owned subsidiaries of
Electronics, which are predecessor entities to the Company. All intercompany
accounts and transactions have been eliminated. The financial position and
results of operations of the Sensors & Systems business segment are presented
as continuing operations and those of the Defense Systems business segment are
presented as discontinued operations. Intercompany accounts and transactions
between Technologies and Electronics are summarized in Note 15. Long-term debt
of Electronics that will be assumed by Technologies in connection with the
Distribution has been included in the accompanying combined balance sheets as
described in Note 5.
 
  The Sensors & Systems business provides sensors, engineered subsystems and
associated components which are used for controlled precision machinery and
equipment in industrial, medical, automotive, aerospace and military
applications.
 
  Fiscal Year: The Company's fiscal year ends on the Saturday nearest
September 30. Fiscal years 1996, 1995 and 1994 each contained 52 weeks.
 
  Interim Financial Information: The combined financial statements for the
nine months ended June 28, 1997 and June 29, 1996 are unaudited but include
all adjustments (consisting of normal recurring adjustments) that the Company
considers necessary for a fair presentation of its financial position and
results of operations. Operating results for the nine months ended June 28,
1997 are not necessarily indicative of the results that may be expected for
any future periods.
 
  Use of Estimates: The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the amounts reported in the financial statements
and the accompanying notes. Actual results could differ from these estimates.
 
  Cash and Cash Equivalents: The Company considers all highly liquid
investments with a maturity of three months or less when purchased to be cash
equivalents.
 
  Concentration of Credit Risk: The Company's products are primarily sold to
commercial customers throughout the United States and in various foreign
countries and to the United States government. Substantially all foreign sales
are denominated in U.S. dollars. The Company performs ongoing credit
evaluations of its commercial customers and generally does not require
collateral. The Company maintains reserves for potential credit losses.
Historically, such losses have been within the expectations of management.
 
  Revenue Recognition: Revenue is recognized under fixed price contracts using
the percentage of completion method, with percentage of completion determined
primarily by units delivered. Units are considered delivered

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
when accepted by the customer. Revenue for products not sold under fixed price
contracts is recognized as units are shipped. Sales under cost reimbursement
contracts are recognized as costs are incurred and include a proportion of the
fees expected to be realized on the contracts. Amounts related to billed
retainages, amounts not billed and amounts of uncertain claims are immaterial.
 
  Inventories: Inventories consist of costs incurred under fixed price
contracts in process less anticipated losses, if any, on the contracts. Other
inventories are carried principally at the lower of cost (first-in, first-out
method) or fair value. Provisions for contract costs in excess of inventory
are reflected as accrued contract costs in current liabilities.
 
  Depreciation and Amortization: Property, plant and equipment are recorded at
cost. Depreciation and amortization are provided in amounts sufficient to
amortize the cost of such assets over their estimated useful lives, which
range from 3 to 30 years, using the straight-line method for structures and
the accelerated or straight-line methods for equipment.
 
  Leasehold improvements are amortized over the shorter of the lease term or
their estimated useful life.
 
  Long Lived Assets: The Company accounts for its long-lived assets using
Financial Accounting Standards Board issued Statement of Financial Accounting
Standard No. 121 ("FAS No. 121") "Accounting for the Impairment of Long-Lived
Assets and Long-Lived Assets to be Disposed Of". The Company adopted FAS
No. 121 on October 1, 1995. The Company recognizes impairment losses on long-
lived assets, including property, plant and equipment and other assets, when
indicators of impairment are present and the undiscounted cash flows estimated
to be generated by those assets are less than the carrying amounts of the
assets.
 
  Tradenames, patents and related assets are being amortized over their
remaining lives at the date of acquisition up to a period of seventeen years.
 
  Technology acquired under license agreements consists primarily of the cost
of exclusive rights to make, use and sell products utilizing quartz rate
sensing technology. Technology acquired is being amortized over thirteen
years, which approximates its estimated useful life from the date of
acquisition.
 
  Goodwill consists of the excess of cost over fair value of net tangible
assets acquired in purchase acquisitions. Goodwill is amortized by the
straight-line method over 20 years.
 
  Research and Development: Costs to develop the Company's products are
expensed as incurred in accordance with Statement of Financial Accounting
Standards No. 2 "Accounting for Research and Development Costs", which
establishes accounting and reporting standards for research and development.
 
  Stock-Based Compensation: In October 1995, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standards No. 123
("FAS 123"), "Accounting for Stock-Based Compensation," which established a
fair-value based method of accounting for stock-based compensation plans and
requires additional disclosures for those companies who elect not to adopt the
new method of accounting. The Company will be required to adopt FAS 123 in
fiscal year 1997. The Company's intention is to continue to account for
employee stock awards in accordance with APB Opinion No. 25 and to adopt the
disclosure-only alternative described in FAS 123.
 
  Pro Forma Net Income Per Share: Pro forma net income per share is based on
the pro forma weighted average number of shares of outstanding Technologies
common stock and dilutive common equivalent shares from stock options, giving
effect to the planned Distribution of one share of Technologies common stock
for each share of Electronics common stock as if it had occurred at the
beginning of each period presented. Pro

forma common equivalent shares from outstanding stock options of Electronics
held by employees of the Sensors and Systems and Defense Systems business who
will become employees of Technologies are computed using the treasury stock
method assuming that upon exercise the holder would receive one share of
Technologies common stock for each share of Electronics common stock acquired
through the exercise of such options.
 
  In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128 ("FAS 128"), "Earnings per Share",
which is required to be adopted for the quarter ending December 27, 1997. At
that time, the Company will be required to change the method currently used to
compute earnings per share and to restate earnings (loss) per share for all
prior periods. Had the Statement been implemented for the nine months ended
June 28, 1997 and the year ended September 28, 1996, the impact on the
calculation of pro forma earnings per share would not have been material.
 
NOTE 2--DISCONTINUED OPERATIONS
 
  In June 30, 1997, the Board of Directors of Electronics announced a formal
plan to discontinue the operations of the Defense Systems segment.
Accordingly, the results of operations of the segment have been presented as
discontinued operations for all periods presented and the assets and
liabilities of the segment have been segregated in the combined balance
sheets. The remaining assets are stated at cost, which management believes
approximates net realizable value and management does not expect any material
loss from the on-going operations or abandonment of the Defense Systems
segment. Previously, in September 1995, Electronics had reached a decision to
exit the HYDRA 70 (H 70) rocket manufacturing line of business which made up a
substantial portion of the Defense Systems segment. Additional products of the
segment included weapons management systems and sales under a cost-plus fee
advanced rocket development contract.
 
  As result of the decision to exit the rocket line of business, the Company
has incurred and will incur costs relating to employee severance and the
closure and withdrawal from the leased facility in Camden, Arkansas and
similar costs related to its owned facility in Euless, Texas. The Company
recorded costs of sales of $1,250,000 as exit costs at September 30, 1995
consisting of employee severance of $750,000, leasehold abandonment of
$250,000 and owned facility costs of $250,000. During fiscal 1996, the Company
incurred $726,000 of costs for employee severance and leasehold and facility
costs of $350,000. Additional amounts were accrued during fiscal 1996 for
severance costs of $350,000 and facility costs of $350,000. During fiscal
1996, the Company recorded net losses of $640,000 on disposal of assets of the
rocket business. At September 28, 1996, an additional charge of $313,000 was
recorded to reflect management's estimate of the fair value of the Euless
facility based on current market conditions. At the end of fiscal year 1996,
the balance in the reserve account consisted of $374,000 and $500,000 for
employee severance and facility closure costs, respectively. During the first
nine months of fiscal 1997, the Company accrued an additional $33,000 for
employee severance costs. Costs incurred during the period for severance and
facilities closure of $302,000 and $357,000, respectively, were charged
against the reserve. The balance in the reserve at the end of the third
quarter of fiscal 1997 consisted of $105,000 for employee severance and
$143,000 for facilities closure costs. Management believes at this time the
reserve appears adequate to cover future shutdown costs. At September 28,
1996, substantially all inventory and equipment assets of the rocket business
had been written off or disposed of except the remaining assets at the Euless
facility which management expects to dispose of in fiscal 1997.

  The Senior Notes, which are obligations of Electronics, have been recorded
in the combined balance sheets of Technologies as the debt was issued to
provide financing for certain acquisitions by Technologies and will be assumed
by Technologies in connection with the Distribution. The interest expense
associated with the Senior Notes has also been allocated to Technologies and
is included in the combined results of operations. The Senior Note Agreement
contains covenants concerning certain financial ratios, dividend payments and
minimum balances of net worth. At September 28, 1996, Electronics was in
compliance with all financial covenants.
 
  Maturities of long-term debt are as follows: fiscal 1997--$5,625,000; 1998--
$8,989,000; 1999--$7,308,000; 2000--$5,600,000; 2001--$2,240,000; thereafter--
none.
 
  Interest of approximately $2,202,000, $2,308,000 and $2,180,000 was paid
during fiscal years 1996, 1995 and 1994, respectively.
 
NOTE 6--INCOME TAXES
 
  Technologies has been included in the consolidated federal income tax return
of Electronics in accordance with the tax allocation arrangement between the
Companies. Income taxes are allocated generally as if the companies had filed
separate U.S. and state income tax returns. After the Distribution,
Technologies will no longer be included in the Electronics consolidated group
and will instead file a separate federal income tax return.
 
  Deferred tax assets and liabilities are determined based on the differences
between financial reporting and the tax basis of assets and liabilities and
are measured using the enacted tax rates and laws known at this time that will
be in effect when the differences are expected to reverse.

  Pursuant to the tax sharing agreement with Electronics, the Company's income
taxes have been paid by Electronics and credited to payable to BEI
Electronics, Inc. (see Note 15).
 
  The Internal Revenue Services (IRS) audited Electronics' income tax returns
for the fiscal years 1993 through 1995. In the third quarter of fiscal year
1997, Electronics reached a settlement with the IRS for all issues raised for
these years, resulting in the payment of $1.7 million in additional taxes for
those years, of which approximately $1.0 million relates to Technologies. The
settlement related primarily to the timing of deductions resulting from
acquisitions made by subsidiaries of the Company. The payment of these
additional taxes resulted in an increase in deferred tax assets and did not
affect the provision for income taxes in the third quarter of fiscal year
1997.

NOTE 11--CONTINGENCIES AND LITIGATION
 
 BEI Systron Donner Company vs. General Precision Industries, Inc., et al.
 
   In January 1997, BEI Systron Donner Company, a division of the Company, and
the former shareholders of General Precision Industries, Inc. (GPI) reached a
confidential settlement of the last remaining issues of the dispute that had
been in arbitration since 1992. Following the November 1996 ruling by the
arbitration panel that GPI may be due costs and expenses, the parties agreed
in their January 1997 settlement on a final payment to fully resolve the
dispute. The impact of the settlement and related legal expenses in the first
quarter of 1997 was an after tax charge of approximately $1.1 million. The
settlement and all remaining amounts accrued for GPI under prior rulings by
the panel, including royalties for 1993 through 1996, were paid in the second
quarter of fiscal 1997.
 
 Claim against U.S. Government
 
  In August, 1995, Defense Systems filed a claim against the U.S. Government
relative to the fuze technical data problems experienced on previous
contracts. The amount of the claim was approximately $5 million. This claim
was settled with the Government in September 1996 for $3.6 million. The
settlement was effected through a contract modification to increase the
selling price of the related rockets by $3.6 million and was recorded as
additional sales in September 1996. Defense Systems also believes it has
rights for additional claims against the Government arising out of the H 70
contract and a substantial claim was filed in 1996. Due to the uncertainties
inherent in the formal claims process, the Company has not recorded any
recoveries for unresolved claims in the accompanying financial statements.
 
 Other
 
  The Company has pending various legal actions arising in the normal course
of business. Management believes that none of these legal actions will have a
material impact on the Company's financial condition or operating results.

NOTE 14--FAIR VALUE OF FINANCIAL INSTRUMENTS
 
  Statement of Financial Accounting Standards No. 107 ("Statement 107"),
"Disclosures about Fair Value of Financial Instruments," requires disclosure
of fair value information about financial instruments, whether or not
recognized in the balance sheet, for which it is practicable to estimate that
value. Whenever possible, quoted market prices were used to develop fair
values. In cases where quoted market prices are not available, fair values are
based on estimates using present value or other valuation techniques. Those
techniques are significantly affected by the assumptions used, including the
discount rate and estimates of future cash flows. In that regard, the derived
fair value estimates cannot be substantiated by comparison to independent
markets, and, in many cases, could not be realized in immediate settlement of
the instrument. Statement 107 excludes certain financial instruments and all
nonfinancial instruments from its disclosure requirements. Accordingly, the
aggregate fair value amounts presented do not represent the underlying value
of the Company. The following methods and assumptions were used by the Company
in estimate its fair value disclosures for financial instruments as of
September 28, 1996, and as of September 30, 1995.
 
  Cash and Cash Equivalents: The carrying amounts reported in the balance
sheet for cash and cash equivalents approximate those assets' fair values.
 
  Long-Term Debt: The fair value of these liabilities has been estimated based
upon the discounted future cash flows. The discount rate used included a risk
free rate derived from the Treasury yield curve plus a risk weighting
commensurate with the Company's borrowing position. The fair value of
Electronics' long-term debt which has been allocated to the Company is
approximately $23,409,000 and $28,806,000 compared with the carrying amounts
of $24,137,000 and $29,765,000 at September 28, 1996 and September 30, 1995,
respectively.
 
NOTE 15--INTERCOMPANY TRANSACTIONS
 
  Amounts payable to Electronics included in the combined balance sheets
represents net balances as the result of various transactions between
Electronics and Technologies. There are no terms of settlement associated with
the account balance. The balance results primarily from of the Company's
participation in Electronics' central cash management program, wherein the
Company's cash receipts are remitted to Electronics and cash disbursements are
funded by Electronics. Other transactions include the Company's share of the
current portion of Electronics consolidated federal and state income tax
liabilities, administrative and other expenses incurred by Electronics on
behalf of Technologies, and interest charges on a portion of the outstanding
balances.
 
  Intercompany transactions are summarized follows:

Board of Directors
BEI Electronics, Inc.
One Post Street--Suite 2500
San Francisco, CA 94104
 
Dear Gentlemen:
   
  We are acting as financial advisors to BEI Electronics, Inc. ("Electronics"
or the "Company") in connection with the proposed distribution of all of the
shares of BEI Technologies, Inc. ("Technologies") common stock to the holders
of Electronics common stock, on a pro rata basis, as more fully described in
the draft of the BEI Technologies, Inc. Form 10 dated September 10, 1997 (the
"Spin-Off"). You have requested our opinion, as of the date hereof, whether
the proposed Spin-Off is fair, from a financial point of view, to the holders
of Electronics common stock.     
 
  SBC Warburg Dillon Read, as part of its investment banking business, is
regularly engaged in the evaluation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings,
competitive bids, secondary distributions of listed and unlisted securities,
private placements and valuations for estate, corporate and other purposes.
For its services, SBC Warburg Dillon Read will receive a fee, part of which is
contingent upon the consummation of the Spin-Off.
 
  In arriving at our opinion, we have: (i) conducted discussions with members
of the senior management of Electronics and with the senior management of
Technologies with regard to the business and prospects of each company; (ii)
analyzed certain historical business and financial information related to
Electronics and Technologies provided to us by Electronics management; (iii)
reviewed certain financial projections for Electronics and Technologies
provided to us by Electronics management; (iv) reviewed public information
relating to Electronics, including Electronics' Annual Report and Form 10-K
for the five fiscal years ended September 28, 1996; (v) reviewed public
information with respect to certain other companies engaged in businesses
which we believed to be generally comparable to certain of the businesses
conducted by Electronics and Technologies; (vi) reviewed the draft of the
Technologies Form 10 dated September 10, 1997 describing the Spin-Off; and
(vii) conducted such other studies, analyses and investigations and reviewed
such other economic and market data as we deemed necessary or appropriate.
 
  We have, with your consent, assumed and relied upon, without independent
verification, the accuracy and completeness of the information reviewed by us
for the purposes of this opinion. With respect to the financial budgets and
forecasts, we have, at your direction, assumed that they have been reasonably
prepared on the bases reflecting the best currently available estimates and
judgments of the future financial performance of Electronics and Technologies.
We have not made any independent valuation or appraisal of the assets or
liabilities, contingent or otherwise, of Electronics or Technologies, nor have
we been furnished with any such evaluation or appraisal. Further, our opinion
is based on economic, monetary and market conditions existing on the date
hereof.
   
  We have noted that Electronics, as a condition to the Distribution, expects
to receive an opinion from Davis, Polk & Wardwell to the effect that, although
the matter is not free from doubt, the Spin-Off will not be a taxable
transaction to the shareholders of Electronics under federal income tax laws.
In that regard, we have, with your consent, assumed that such opinion will be
delivered to Electronics.     
<PAGE>
 
  In rendering our opinion we are not opining as to the price at which the
common stock of Electronics or Technologies will trade after the Spin-Off is
effected or as to the valuation or long-term viability of Electronics or
Technologies as independent public companies following the Spin-Off. This
opinion does not constitute a recommendation to any current or prospective
shareholder of either Electronics or Technologies as to any action or
investment decision such party or person may take.
 
  Based upon and subject to the foregoing and recognizing that the proposed
Distribution is pro-rata to holders of Electronics shares, we are of the
opinion as of the date hereof that the proposed Spin-Off is fair, from a
financial point of view, to the holders of Electronics common stock.
 
                                          Very truly yours,
 
                                          SBC Warburg Dillon Read

                                RIGHTS AGREEMENT


     This RIGHTS AGREEMENT ("AGREEMENT"), dated as of September 11, 1997,
between BEI TECHNOLOGIES, INC., a Delaware corporation (the "Company"), and
CHASEMELLON SHAREHOLDER SERVICES, L.L.C. ("Rights Agent").

     The Board of Directors of the Company has authorized and declared a
dividend of one preferred share purchase right (a "Right") for each Common Share
(as such term is hereinafter defined) outstanding at the close of business on
September 29, 1997 (the "Record Date"), each Right representing the right to
purchase one one-hundredth of a Preferred Share (as such term is hereinafter
defined), upon the terms and subject to the conditions herein set forth, and has
further authorized and directed the issuance of one Right with respect to each
Common Share that shall become outstanding between the Record Date and the
earliest to occur of the Distribution Date, the Redemption Date and the Final
Expiration Date (as such terms are hereinafter defined); provided, however, that
Rights may be issued with respect to Common Shares that shall become outstanding
after the Distribution Date and prior to the earlier of the Redemption Date and
the Final Expiration Date in accordance with the provisions of Section 22
hereof.

     Accordingly, in consideration of the premises and the mutual agreements
herein set forth, the parties hereby agree as follows:

     SECTION 1.  CERTAIN DEFINITIONS.  For purposes of this Agreement, the
following terms have the meanings indicated:

     (a) "ACQUIRING PERSON" shall mean any Person (as such term is hereinafter
defined) who or which, together with all Affiliates and Associates (as such
terms are hereinafter defined) of such Person, shall be the Beneficial Owner (as
such term is hereinafter defined) of fifteen percent (15%) or more of the Common
Shares then outstanding.  Notwithstanding the foregoing, (A) the term Acquiring
Person shall not include (i) the Company, (ii) any Subsidiary (as such term is
hereinafter defined) of the Company, (iii) any employee benefit or compensation
plan of the Company or any Subsidiary of the Company, (iv) any entity holding
Common Shares for or pursuant to the terms of any such employee benefit or
compensation plan, or (v) an Excluded Person (as such term is hereinafter
defined) and (B) no Person shall become an "Acquiring Person" either (x) as the
result of an acquisition of Common Shares by the Company which, by reducing the
number of shares outstanding, increases the proportionate number of shares
beneficially owned by such Person to fifteen percent (15%) or more of the Common
Shares then outstanding; provided, however, that if a Person shall become the
Beneficial Owner of fifteen percent (15%) or more of the Common Shares then
outstanding by reason of share purchases by the Company and shall, following
written notice from, or public disclosure by the Company of such share purchases
by the Company, become the Beneficial Owner of any additional Common Shares
without the prior consent of the Company and shall then Beneficially Own more
than fifteen percent (15%) of the Common Shares then outstanding, then such
Person shall be deemed to be an "Acquiring Person," or (y) if the Board of
Directors determines in good faith that a Person who would otherwise be an
"Acquiring Person," as defined pursuant to the

                                       1
<PAGE>
 
foregoing provisions of this paragraph (a), has become such inadvertently, and
such Person divests, as promptly as practicable (as determined in good faith by
the Board of Directors), but in any event within five Business Days, following
receipt of written notice from the Company of such event, of a sufficient number
of Common Shares so that such Person would no longer be an Acquiring Person, as
defined pursuant to the foregoing provisions of this paragraph (a), then such
Person shall not be deemed to be an "Acquiring Person" for any purposes of this
Agreement.

     (b) "AFFILIATE" and "ASSOCIATE" shall have the respective meanings ascribed
to such terms in Rule 12b-2 of the General Rules and Regulations under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), as in effect
on the date of this Agreement; provided, however, that the limited partners of a
limited partnership shall not be deemed to be Associates of such limited
partnership solely by virtue of their limited partnership interests.

     (c) A Person shall be deemed the "BENEFICIAL OWNER" of and shall be deemed
to "beneficially own" any securities:

          (i)   which such Person or any of such Person's Affiliates or
Associates is deemed to beneficially own, within the meaning of Rule 13d-3 of
the General Rules and Regulations under the Exchange Act as in effect on the
date of this Rights Agreement;

          (ii)  which such Person or any of such Person's Affiliates or
Associates has (A) the right to acquire (whether such right is exercisable
immediately or only after the passage of time) pursuant to any agreement,
arrangement or understanding (other than customary agreements with and between
underwriters and selling group members with respect to a bona fide public
offering of securities, or upon the exercise of conversion rights, exchange
rights, rights (other than these Rights), warrants or options, or otherwise;
provided, however, that a Person shall not be deemed the Beneficial Owner of, or
to beneficially own, securities tendered pursuant to a tender or exchange offer
made by or on behalf of such Person or any of such Person's Affiliates or
Associates until such tendered securities are accepted for purchase or exchange;
or (B) the right to vote pursuant to any agreement, arrangement or
understanding; provided, however, that a Person shall not be deemed the
Beneficial Owner of, or to beneficially own, any security if the agreement,
arrangement or understanding to vote such security (1) arises solely from a
revocable proxy or consent given to such Person in response to a public proxy or
consent solicitation made pursuant to, and in accordance with, the applicable
rules and regulations promulgated under the Exchange Act and (2) is not also
then reportable on Schedule 13D under the Exchange Act (or any comparable or
successor report); or

          (iii)  which are beneficially owned, directly or indirectly, by any
other Person with which such Person or any of such Person's Affiliates or
Associates has any agreement, arrangement or understanding (other than customary
agreements with and between underwriters and selling group members with respect
to a bona fide public offering of securities) for the purpose of acquiring,
holding, voting (except to the extent contemplated by the proviso to Section
1(c)(ii)(B) hereof) or disposing of any securities of the Company.

Notwithstanding anything in this definition of Beneficial Ownership to the
contrary, the phrase, "then outstanding," when used with reference to a Person's
Beneficial Ownership of securities

                                       2
<PAGE>

outstanding together with the number of such securities not then actually issued
and outstanding which such Person would be deemed to own beneficially hereunder.

     (d) "BUSINESS DAY" shall mean any day other than a Saturday, a Sunday, or a
day on which banking institutions in the State of California are authorized or
obligated by law or executive order to close.

     (e) "CLOSE OF BUSINESS" on any given date shall mean 5:00 p.m., Pacific
Time, on such date; provided, however, that if such date is not a Business Day
it shall mean 5:00 p.m., Pacific Time, on the next succeeding Business Day.

     (f) "COMMON SHARES" shall mean the shares of common stock, par value $.001
per share, of the Company; provided, however, that, "Common Shares," when used
in this Agreement in connection with a specific reference to any Person other
than the Company, shall mean the capital stock (or equity interest) with the
greatest voting power of such other Person or, if such other Person is a
Subsidiary of another Person, the Person or Persons which ultimately control
such first-mentioned Person.

     (g) "DISTRIBUTION DATE" shall have the meaning set forth in Section 3
hereof.

     (h) "EXCLUDED PERSON" shall mean Charles Crocker and any trust or other
fiduciary account for the benefit of Mr. Crocker or his ancestors, descendants,
siblings or spouse (a "Trust") so long as such persons collectively beneficially
own thirty percent (30%) or less of the outstanding Common Shares; provided,
however, that Charles Crocker and any Trust shall not be an Excluded Person if
such persons beneficially own more than thirty percent (30%) of the outstanding
Common Shares without the prior approval of the Board of Directors of the
Company.

     (i) "FINAL EXPIRATION DATE" shall have the meaning set forth in Section 7
hereof.

     (j) "INTERESTED STOCKHOLDER" shall mean any Acquiring Person or any
Affiliate or Associate of an Acquiring Person or any other Person in which any
such Acquiring Person, Affiliate or Associate has an interest, or any other
Person acting directly or indirectly on behalf of or in concert with any such
Acquiring Person, Affiliate or Associate.

<PAGE>
 
     (o) "SHARES ACQUISITION DATE" shall mean the first date of public
announcement by the Company or an Acquiring Person that an Acquiring Person has
become such; provided, however, that, if such Person is determined not to have
become an Acquiring Person pursuant to clause (z) of Subsection 1(a)(B) hereof,
then no Shares Acquisition Date shall be deemed to have occurred.

     (p) "SUBSIDIARY" of any Person shall mean any corporation or other entity

     SECTION 2.  APPOINTMENT OF RIGHTS AGENT.  The Company hereby appoints the
Rights Agent to act as agent for the Company in accordance with the terms and

Company may from time to time appoint such co-Rights Agents as it may deem
necessary or desirable.

     SECTION 3.  ISSUE OF RIGHT CERTIFICATES.

     (a) Until the earlier of (i) the Shares Acquisition Date or (ii) the tenth
Business Day (or such later date as may be determined by action of the Board of
Directors prior to such time as any Person becomes an Acquiring Person) after
the date of the commencement (determined in accordance with Rule 14d-2 under the
Exchange Act) by any Person (other than the Company, any Subsidiary of the
Company, any employee benefit plan of the Company or of any Subsidiary of the
Company or any entity holding Common Shares for or pursuant to the terms of any
such plan) of, or of the first public announcement of the intention of any
Person (other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or of any Subsidiary of the Company or any entity
holding Common Shares for or pursuant to the terms of any such plan) to
commence, a tender or exchange offer (which intention to commence remains in
effect for five Business Days after such announcement), the consummation of
which would result in any Person becoming an Acquiring Person (including any
such date which is after the date of this Agreement and prior to the issuance of
the Rights, the earlier of such dates being herein referred to as the
"Distribution Date"), (x) the Rights will be evidenced by the certificates for
Common Shares registered in the names of the holders thereof (which certificates
shall also be deemed to be Right Certificates) and not by separate Right
Certificates, and (y) the Rights (and the right to receive Right Certificates
therefor) will be transferable only in connection with the transfer of Common
Shares.  As soon as practicable after the Distribution Date, the Company will
prepare and execute, the Rights Agent will countersign, and the Company will
send or cause to be sent (and the Rights Agent will, if requested, send) by
first-

                                       4
<PAGE>
 
class, insured, postage-prepaid mail, to each record holder of Common Shares as
of the Close of Business on the Distribution Date, at the address of such holder
shown on the records of the Company, a Right Certificate, in substantially the
form of Exhibit B hereto (a "Right Certificate"), evidencing one Right for each
Common Share so held, subject to the adjustment provisions of Section 11 of this
Rights Agreement.  As of the Distribution Date, the Rights will be evidenced
solely by such Right Certificates.

     (b) On the Record Date, or as soon as practicable thereafter, the Company
will send (directly or through the Rights Agent or its transfer agent) a copy of
a Summary of Rights to Purchase Preferred Shares, in substantially the form of
Exhibit C hereto (the "Summary of Rights"), by first-class, postage-prepaid
mail, to each record holder of Common Shares as of the Close of Business on the
Record Date, at the address of such holder shown on the records of the Company.
With respect to certificates for Common Shares outstanding as of the Record
Date, until the Distribution Date, the Rights will be evidenced by such
certificates registered in the names of the holders thereof.  Until the
Distribution Date (or the earlier of the Redemption Date and the Final
Expiration Date), the surrender for transfer of any certificate for Common
Shares outstanding on the Record Date shall also constitute the transfer of the
Rights associated with the Common Shares represented thereby.

     (c) Certificates for Common Shares which become outstanding (including,
without limitation, reacquired Common Shares referred to in the last sentence of
this paragraph (c)) after the Record Date but prior to the earliest of the
Distribution Date, the Redemption Date or the Final Expiration Date shall have
impressed on, printed on, written on or otherwise affixed to them the following
legend:

          This certificate also evidences and entitles the holder hereof to
          certain rights as set forth in a Rights Agreement between BEI
          Technologies, Inc. (the "Company") and ChaseMellon Shareholder
          Services, L.L.C. as Rights Agent (the "Rights Agent"), dated as of
          September 11, 1997, as amended from time to time (the "Rights
          Agreement"), the terms of which are hereby incorporated herein by
          reference and a copy of which is on file at the principal executive
          offices of the Company.  Under certain circumstances, as set forth in
          the Rights Agreement, such Rights will be evidenced by separate
          certificates and will no longer be evidenced by this certificate.  The
          Company will mail to the holder of this certificate a copy of the
          Rights Agreement without charge after receipt of a written request
          therefor.  As described in the Rights Agreement, Rights issued to any
          Person who becomes an Acquiring Person or an Affiliate or Associate
          thereof (as defined in the Rights Agreement) and certain related
          persons, whether currently held by or on behalf of such Person or by
          any subsequent holder, shall become null and void.

With respect to such certificates containing the foregoing legend, until the
Distribution Date, the Rights associated with the Common Shares represented by
such certificates shall be evidenced by such certificates alone, and the
surrender for transfer of any such certificate shall also

                                       5
<PAGE>
 
constitute the transfer of the Rights associated with the Common Shares
represented thereby.  In the event that the Company purchases or acquires any
Common Shares after the Record Date but prior to the Distribution Date, any
Rights associated with such Common Shares shall be deemed canceled and retired
so that the Company shall not be entitled to exercise any Rights associated with
the Common Shares which are no longer outstanding.  Notwithstanding this Section
3(c), the omission of a legend shall not affect the enforceability of any part
of this Rights Agreement or the rights of any holder of the Rights.

     SECTION 4.  FORM OF RIGHT CERTIFICATES.

     (a) The Right Certificates (and the form of election to purchase Preferred
Shares, the form of assignment and the form of certification to be printed on
the reverse thereof) shall be substantially the same as Exhibit B hereto and may
have such marks of identification or designation and such legends, summaries or
endorsements printed thereon as the Company may deem appropriate and as are not
inconsistent with the provisions of this Agreement, or as may be required to
comply with any applicable law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any stock exchange on which the Rights
may from time to time be listed, or to conform to usage.  Subject to the
provisions of Sections 7,11 and 22 hereof, the Right Certificates shall entitle
the holders thereof to purchase such number of one one-hundredths of a Preferred
Share as shall be set forth therein at the price per one one-hundredth of a
Preferred Share set forth therein (the "Purchase Price"), but the number of such
one one-hundredths of a Preferred Share and the Purchase Price shall be subject
to adjustment as provided herein.

     (b) Any Right Certificate issued pursuant to Section 3(a) or Section 22
hereof that represents Rights which are null and void pursuant to Section
11(a)(ii) hereof and any Right Certificate issued pursuant to Section 6 or
Section 11 hereof upon transfer, exchange, replacement or adjustment of any
other Right Certificate referred to in this sentence, shall contain (to the
extent feasible) the following legend:

          The Rights represented by this Right Certificate are or were
          beneficially owned by a Person who was or became an Acquiring Person
          or an Affiliate or Associate of an Acquiring Person (as such terms are
          defined in the Rights Agreement). Accordingly, this Right Certificate
          and the Rights represented hereby are null and void.

The provisions of Section 11(a)(ii) hereof shall be operative whether or not the
foregoing legend is contained on any such Right Certificate.

     SECTION 5.  COUNTERSIGNATURE AND REGISTRATION.  The Right Certificates
shall be executed on behalf of the Company by its Chairman of the Board, its
Chief Executive Officer, its President, its Vice Chairman of the Board, its
Chief Financial Officer, or any of its Vice Presidents, either manually or by
facsimile signature, shall have affixed thereto the Company's seal or a
facsimile thereof, and shall be attested by the Secretary or an Assistant
Secretary of the Company, either manually or by facsimile signature.  The Right
Certificates shall be manually countersigned by the Rights Agent and shall not
be valid for any purpose unless

                                       6
<PAGE>
 
countersigned.  In case any officer of the Company who shall have signed any of
the Right Certificates shall cease to be such officer of the Company before
countersignature by the Rights Agent and issuance and delivery by the Company,
such Right Certificates, nevertheless, may be countersigned by the Rights Agent
and issued and delivered by the Company with the same force and effect as though
the person who signed such Right Certificates had not ceased to be such officer
of the Company; and any Right Certificate may be signed on behalf of the Company
by any person who, at the actual date of the execution of such Right
Certificate, shall be a proper officer of the Company to sign such Right
Certificate, although at the date of the execution of this Agreement any such
person was not such an officer.

     Following the Distribution Date, the Rights Agent will keep or cause to be
kept, at its office designated for such purpose, books for registration and
transfer of the Right Certificates issued hereunder.  Such books shall show the
names and addresses of the respective holders of the Right Certificates, the
number of Rights evidenced on its face by each of the Right Certificates and the
date of each of the Right Certificates.

     SECTION 6.  TRANSFER, SPLIT UP, COMBINATION AND EXCHANGE OF RIGHT
CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN RIGHT CERTIFICATES.  Subject
to the provisions of Section 11(a)(ii), Section 14 and Section 24 hereof, at any
time after the Close of Business on the Distribution Date, and at or prior to
the Close of Business on the earlier of the Redemption Date or the Final
Expiration Date, any Right Certificate or Right Certificates may be transferred,
split up, combined or exchanged for another Right Certificate or Right
Certificates, entitling the registered holder to purchase a like number of one
one-hundredths of a Preferred Share as the Right Certificate or Right
Certificates surrendered then entitled such holder to purchase.  Any registered
holder desiring to transfer, split up, combine or exchange any Right Certificate
or Right Certificates shall make such request in writing delivered to the Rights
Agent, and shall surrender the Right Certificate or Right Certificates to be
transferred, split up, combined or exchanged at the office of the Rights Agent
designated for such purpose.  Neither the Rights Agent nor the Company shall be
obligated to take any action whatsoever with respect to the transfer of any such
surrendered Right Certificate until the registered holder shall have completed
and signed the certificate contained in the form of assignment on the reverse
side of such Right Certificate and shall have provided such additional evidence
of the identity of the Beneficial Owner (or former Beneficial Owner) or
Affiliates or Associates thereof as the Company shall reasonably request.
Thereupon the Rights Agent shall, subject to Section 11(a)(ii), Section 14 and
Section 24 hereof, countersign and deliver to the person entitled thereto a
Right Certificate or Right Certificates, as the case may be, as so requested.
The Company may require payment of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with any transfer, split
up, combination or exchange of Right Certificates.

     Upon receipt by the Company and the Rights Agent of evidence reasonably
satisfactory to them of the loss, theft, destruction or mutilation of a Right
Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to them, and, at the Company's request,
reimbursement to the Company and the Rights Agent of all reasonable expenses
incidental thereto, and upon surrender to the Rights Agent and cancellation of
the Right Certificate if mutilated, the Company will issue, execute and deliver
a new Right Certificate of

                                       7
<PAGE>
 
like tenor to the Rights Agent for countersignature and delivery to the
registered holder in lieu of the Right Certificate so lost, stolen, destroyed or
mutilated.

     Notwithstanding any other provisions hereof, the Company and the Rights
Agent may amend this Rights Agreement to provide for uncertificated Rights in
addition to or in place of Rights evidenced by Rights Certificates.

     SECTION 7.  EXERCISE OF RIGHTS; PURCHASE PRICE; EXPIRATION DATE OF RIGHTS.

     (a) The registered holder of any Right Certificate may exercise the Rights
evidenced thereby (except as otherwise provided herein) in whole or in part at
any time after the Distribution Date upon surrender of the Right Certificate,
with the form of election to purchase on the reverse side thereof duly executed,
to the Rights Agent at the office of the Rights Agent designated for such
purpose, together with payment of the Purchase Price for each one one-hundredth
of a Preferred Share (or such other number of shares or other securities) as to
which the Rights are exercised, at or prior to the earliest of (i) the Close of
Business on September 10, 2007 (the "Final Expiration Date"), (ii) the time at
which the Rights are redeemed as provided in Section 23 hereof (the "Redemption
Date"), or (iii) the time at which such Rights are exchanged as provided in
Section 24 hereof.

     (b) The purchase price (the "Purchase Price") for each one one-hundredth of
a Preferred Share pursuant to the exercise of a Right shall initially be Seventy
Dollars ($70.00), shall be subject to adjustment from time to time as provided
in Sections 11 and 13 hereof and shall be payable in lawful money of the United
States of America in accordance with paragraph (c) below.

     (c) Upon receipt of a Right Certificate representing exercisable Rights,
with the form of election to purchase duly executed, accompanied by payment of
the Purchase Price for the shares to be purchased and an amount equal to any
applicable transfer tax required to be paid by the holder of such Right
Certificate in accordance with Section 9 hereof by certified check, cashier's
check, bank draft or money order payable to the order of the Company, the Rights
Agent shall thereupon promptly (i) (A) requisition from any transfer agent for
the Preferred Shares certificates for the number of Preferred Shares to be
purchased and the Company hereby irrevocably authorizes its transfer agent to
comply with all such requests, or (B) if the Company, in its sole discretion,
shall have elected to deposit the Preferred Shares issuable upon exercise of the
Rights hereunder into a depository, requisition from the depositary agent
depositary receipts representing such number of one one-hundredths of a
Preferred Share as are to be purchased (in which case certificates for the
Preferred Shares represented by such receipts shall be deposited by the transfer
agent with the depositary agent) and the Company hereby directs the depositary
agent to comply with such request, (ii) when appropriate, requisition from the
Company the amount of cash to be paid in lieu of issuance of fractional shares
in accordance with Section 14 hereof, (iii) after receipt of such certificates
or depositary receipts, cause the same to be delivered to or upon the order of
the registered holder of such Right Certificate, registered in such name or
names as may be designated by such holder and (iv) when appropriate, after
receipt, deliver such cash to or upon the order of the registered holder of such
Right Certificate.  In the event that the Company is obligated to issue
securities of the Company other than Preferred Shares (including Common Shares)
of the Company pursuant to Section

                                       8
<PAGE>
 
11(a) hereof, the Company will make all arrangements necessary so that such
other securities are available for distribution by the Rights Agent, if and when
appropriate.

     In addition, in the case of an exercise of the Rights by a holder pursuant
to Section 11(a)(ii) hereof, the Rights Agent shall return such Right
Certificate to the registered holder thereof after imprinting, stamping or
otherwise indicating thereon that the rights represented by such Right
Certificate no longer include the rights provided by Section 11(a)(ii) hereof,
and, if fewer than all the Rights represented by such Right Certificate were so
exercised, the Rights Agent shall indicate on the Right Certificate the number
of Rights represented thereby which continue to include the rights provided by
Section 11(a)(ii) hereof.

     (d) In case the registered holder of any Right Certificate shall exercise
fewer than all the Rights evidenced thereby, a new Right Certificate evidencing
Rights equivalent to the Rights remaining unexercised shall be issued by the
Rights Agent to the registered holder of such Right Certificate or to his duly
authorized assigns, subject to the provisions of Section 14 hereof.

     (e) The Company covenants and agrees that it will cause to be reserved and
kept available out of its authorized and unissued Preferred Shares or any
Preferred Shares held in its treasury, the number of Preferred Shares that will
be sufficient to permit the exercise in full of all outstanding Rights in
accordance with this Section 7.

     (f) Notwithstanding anything in this Agreement to the contrary, neither the
Rights Agent nor the Company shall be obligated to undertake any action with
respect to a registered holder upon the occurrence of any purported exercise as
set forth in this Section 7 unless such registered holder shall have (i)
completed and signed the certification following the form of election to
purchase set forth on the reverse side of the Rights Certificate surrendered for
such exercise and (ii) provided such additional evidence of the identity of the
Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates
thereof as the Company shall reasonably request.

     SECTION 8.  CANCELLATION AND DESTRUCTION OF RIGHT CERTIFICATES.  All Right
Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or to any of its
agents, be delivered to the Rights Agent for cancellation or in canceled form,
or, if delivered or surrendered to the Rights Agent, shall be canceled by it,
and no Right Certificates shall be issued in lieu thereof except as expressly
permitted by any of the provisions of this Agreement.  The Company shall deliver
to the Rights Agent for cancellation and retirement, and the Rights Agent shall
so cancel and retire, any other Right Certificate purchased or acquired by the
Company otherwise than upon the exercise thereof.  The Rights Agent shall
deliver all canceled Right Certificates to the Company, or shall, at the written
request of the Company, destroy such canceled Right Certificates, and in such
case shall deliver a certificate of destruction thereof to the Company.

     SECTION 9.  AVAILABILITY OF PREFERRED SHARES.  The Company covenants and
agrees that so long as the Preferred Shares (and, after the time a person
becomes an Acquiring Person, Common Shares or any other securities) issuable
upon the exercise of the Rights may be listed on any national securities
exchange or quotation system, the Company shall use its best efforts to cause,
from and after such time as the Rights become exercisable, all shares reserved
for such

                                       9
<PAGE>
 
issuance to be listed on such exchange or quotation system upon official notice
of issuance upon such exercise.

     The Company covenants and agrees that it will take all such action as may
be necessary to ensure that all Preferred Shares (or Common Shares and other
securities, as the case may be) delivered upon exercise of Rights shall, at the
time of delivery of the certificates for such Preferred Shares (subject to
payment of the Purchase Price), be duly and validly authorized and issued and
fully paid and nonassessable shares or other securities.

     The Company further covenants and agrees that it will pay when due and
payable any and all federal and state transfer taxes and charges which may be
payable in respect of the issuance or delivery of the Right Certificates or of
any Preferred Shares upon the exercise of Rights.  The Company shall not,
however, be required to pay any transfer tax which may be payable in respect of
any transfer or delivery of Right Certificates to a person other than, or the
issuance or delivery of certificates or depositary receipts for the Preferred
Shares in a name other than that of, the registered holder of the Right
Certificate evidencing Rights surrendered for exercise or to issue or to deliver
any certificates or depositary receipts for Preferred Shares upon the exercise
of any Rights until any such tax shall have been paid (any such tax being
payable by the holder of such Right Certificate at the time of surrender) or
until it has been established to the Company's reasonable satisfaction that no
such tax is due.

     As soon as practicable after the Shares Acquisition Date, the Company shall
use its best efforts to:

     (a) prepare and file a registration statement under the Securities Act of
1933, as amended (the "Act"), with respect to the Rights and the securities
purchasable upon exercise of the Rights on an appropriate form, will use its
best efforts to cause such registration statement to become effective as soon as
practicable after such filing and will use its best efforts to cause such
registration statement to remain effective (with a prospectus at all times
meeting the requirements of the Act) until the Final Expiration Date; and

     (b) use its best efforts to qualify or register the Rights and the
securities purchasable upon exercise of the Rights under the blue sky laws of
such jurisdictions as may be necessary or appropriate.

     SECTION 10.  PREFERRED SHARES RECORD DATE.  Each person in whose name any
certificate for Preferred Shares or other securities is issued upon the exercise
of Rights shall for all purposes be deemed to have become the holder of record
of the Preferred Shares or other securities represented thereby on, and such
certificate shall be dated, the date upon which the Right Certificate evidencing
such Rights was duly surrendered with the forms of election and certification
duly executed and payment of the Purchase Price (and any applicable transfer
taxes) was made; provided, however, that if the date of such surrender and
payment is a date upon which the Preferred Shares or other securities transfer
books of the Company are closed, such person shall be deemed to have become the
record holder of such shares on, and such certificate shall be dated, the next
succeeding Business Day on which the Preferred Shares or other securities
transfer books of the Company are open.  Prior to the exercise of the Rights
evidenced thereby, the holder of a Right Certificate, as such, shall not be
entitled to any rights of a holder

                                       10
<PAGE>
 
of Preferred Shares for which the Rights shall be exercisable, including,
without limitation, the right to vote, to receive dividends or other
distributions or to exercise any preemptive rights, and shall not be entitled to
receive any notice of any proceedings of the Company, except as provided herein.

     SECTION 11.  ADJUSTMENT OF PURCHASE PRICE, NUMBER OF SHARES OR NUMBER OF
RIGHTS.  The Purchase Price, the number of Preferred Shares covered by each
Right and the number of Rights outstanding are subject to adjustment from time
to time as provided in this Section 11.

     (a)  (i)  In the event the Company shall at any time after the date of this
Agreement (A) declare a dividend on the Preferred Shares payable in Preferred
Shares, (B) subdivide the outstanding Preferred Shares, (C) combine the
outstanding Preferred Shares into a smaller number of Preferred Shares or (D)
issue any shares of its capital stock in a reclassification of the Preferred
Shares (including any such reclassification in connection with a consolidation
or merger in which the Company is the continuing or surviving corporation),
except as otherwise provided in this Section 11(a), the Purchase Price in effect
at the time of the record date for such dividend or of the effective date of
such subdivision, combination or reclassification, and the number and kind of
shares of capital stock issuable on such date, shall be proportionately adjusted
so that the holder of any Right exercised after such time shall be entitled to
receive the aggregate number and kind of shares of capital stock which, if such
Right had been exercised immediately prior to such date and at a time when the
Preferred Shares transfer books of the Company were open, such holder would have
owned upon such exercise and been entitled to receive by virtue of such
dividend, subdivision, combination or reclassification; provided, however, that
in no event shall the consideration to be paid upon the exercise of one Right be
less than the aggregate par value of the shares of capital stock of the Company
issuable upon exercise of one Right.  If an event occurs which would require an
adjustment under both Section 11(a)(i) and Section 11(a)(ii) hereof, the
adjustment provided for in this Section 11(a)(i) shall be in addition to, and
shall be made prior to any adjustment required pursuant to Section 11(a)(ii)
hereof.

          (ii) Subject to Section 24 hereof and the provisions of the next
paragraph of this Section 11(a)(ii), in the event any Person shall become an
Acquiring Person, each holder of a Right shall, for a period of 60 days after
the later of such time any Person becomes an Acquiring Person or the effective
date of an appropriate registration statement under the Act pursuant to Section
9 hereof (provided, however, that, if at any time prior to the expiration or
termination of the Rights there shall be a temporary restraining order, a
preliminary injunction, an injunction, or temporary suspension by the Board of
Directors, or similar obstacle to exercise of the Rights (the "Injunction")
which prevents exercise of the Rights, a new 60-day period shall commence on the
date the Injunction is removed), have a right to receive, upon exercise thereof
at a price equal to the then current Purchase Price multiplied by the number of
one one-hundredths of a Preferred Share for which a Right is then exercisable,
in accordance with the terms of this Agreement and in lieu of Preferred Shares,
such number of Common Shares as shall equal the result obtained by (A)
multiplying the then current Purchase Price by the number of one one-hundredths
of a Preferred Share for which a Right is then exercisable and dividing that
product by (B) fifty percent (50%) of the then current per share market price of
the Common Shares (determined pursuant to Section 11(d) hereof) on the date such
Person became an Acquiring Person; provided, however, that if the transaction
that would otherwise give rise

                                       11
<PAGE>
 
to the foregoing adjustment is also subject to the provisions of Section 13
hereof, then only the provisions of Section 13 hereof shall apply and no
adjustment shall be made pursuant to this Section 11(a)(ii).  In the event that
any Person shall become an Acquiring Person and the Rights shall then be
outstanding, the Company shall not take any action which would eliminate or
diminish the benefits intended to be afforded by the Rights.

     Notwithstanding anything in this Agreement to the contrary, from and after
the time any Person becomes an Acquiring Person, any Rights beneficially owned
by (i) such Acquiring Person or an Associate or Affiliate of such Acquiring
Person, (ii) a transferee of such Acquiring Person (or of any such Associate or
Affiliate) who becomes a transferee after the Acquiring Person became such, or
(iii) a transferee of such Acquiring Person (or of any such Associate or
Affiliate) who becomes a transferee prior to or concurrently with the Acquiring
Person's becoming such and receives such Rights pursuant to either (A) a
transfer (whether or not for consideration) from the Acquiring Person to holders
of equity interests in such Acquiring Person or to any Person with whom the
Acquiring Person has any continuing agreement, arrangement or understanding
regarding the transferred Rights or (B) a transfer which the Board of Directors
of the Company has determined is part of a plan, arrangement or understanding
which has as a primary purpose or effect the avoidance of this Section
11(a)(ii), shall become null and void without any further action and no holder
of such Rights shall have any rights whatsoever with respect to such Rights,
whether under any provision of this Agreement or otherwise.  The Company shall
use all reasonable efforts to insure that the provisions of this Section
11(a)(ii) and Section 4(b) hereof are complied with, but shall have no liability
to any holder of Right Certificates or other Person as a result of its failure
to make any determinations with respect to an Acquiring Person or its
Affiliates, Associates or transferees hereunder.  No Right Certificate shall be
issued at any time upon the transfer of any Rights to an Acquiring Person whose
Rights would be void pursuant to the preceding sentence or any Associate or
Affiliate thereof or to any nominee of such Acquiring Person, Associate or
Affiliate; and any Right Certificate delivered to the Rights Agent for transfer
to an Acquiring Person whose Rights would be void pursuant to the preceding
sentence shall be canceled.

          (iii)  In lieu of issuing Common Shares in accordance with Section
11(a)(ii) hereof, the Company may, if a majority of the Board of Directors then
in office determines that such action is necessary or appropriate and not
contrary to the interests of holders of Rights, elect to (and, in the event that
the Board of Directors has not exercised the exchange right contained in Section
24(c) hereof and there are not sufficient treasury shares and authorized but
unissued Common Shares to permit the exercise in full of the Rights in
accordance with the foregoing subparagraph (ii), the Company shall) take all
such action as may be necessary to authorize, issue or pay, upon the exercise of
the Rights, cash (including by way of a reduction of the Purchase Price),
property, Common Shares, other securities or any combination thereof having an
aggregate value equal to the value of the Common Shares which otherwise would
have been issuable pursuant to Section 11(a)(ii) hereof, which aggregate value
shall be determined by a nationally recognized investment banking firm selected
by a majority of the Board of Directors then in office.  For purposes of the
preceding sentence, the value of the Common Shares shall be determined pursuant
to Section 11(d) hereof.  Any such election by the Board of Directors must be
made within 60 days following the date on which the event described in Section
11(a)(ii) hereof shall have occurred.  Following the occurrence of the event
described in Section 11(a)(ii) hereof, a majority of the Board of Directors then
in office may suspend the exercisability of the

                                       12
<PAGE>
 
Rights for a period of up to 60 days following the date on which the event
described in Section 11(a)(ii) hereof shall have occurred to the extent that
such directors have not determined whether to exercise their rights of election
under this Section 11(a)(iii).  In the event of any such suspension, the Company
shall issue a public announcement stating that the exercisability of the Rights
has been temporarily suspended.

     (b) In case the Company shall fix a record date for the issuance of rights,
options or warrants to all holders of Preferred Shares entitling them (for a
period expiring within 45 calendar days after such record date) to subscribe for
or purchase Preferred Shares (or shares having the same designations and the
powers, preferences and rights, and the qualifications, limitations and
restrictions as the Preferred Shares ("equivalent preferred shares")) or
securities convertible into Preferred Shares or equivalent preferred shares at a
price per Preferred Share or equivalent preferred share (or having a conversion
price per share, if a security convertible into Preferred Shares or equivalent
preferred shares) less than the then current per share market price of the
Preferred Shares (as such term is hereinafter defined) on such record date, the
Purchase Price to be in effect after such record date shall be determined by
multiplying the Purchase Price in effect immediately prior to such record date
by a fraction, the numerator of which shall be the number of Preferred Shares
outstanding on such record date plus the number of Preferred Shares which the
aggregate offering price of the total number of Preferred Shares and/or
equivalent preferred shares so to be offered (and/or the aggregate initial
conversion price of the convertible securities so to be offered) would purchase
at such current market price and the denominator of which shall be the number of
Preferred Shares outstanding on such record date plus the number of additional
Preferred Shares and/or equivalent preferred shares to be offered for
subscription or purchase (or into which the convertible securities so to be
offered are initially convertible); provided, however, that in no event shall
the consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right.  In case such subscription price may be paid in a
consideration part or all of which shall be in a form other than cash, the value
of such consideration shall be as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent.  Preferred Shares owned by or held for the account
of the Company shall not be deemed outstanding for the purpose of any such
computation.  Such adjustment shall be made successively whenever such a record
date is fixed; and in the event that such rights, options or warrants are not so
issued, the Purchase Price shall be adjusted to be the Purchase Price which
would then be in effect if such record date had not been fixed.

     (c) In case the Company shall fix a record date for the making of a
distribution to all holders of the Preferred Shares (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation) of evidences of indebtedness
or assets (other than a regular quarterly cash dividend or a dividend payable in
Preferred Shares) or subscription rights or warrants (excluding those referred
to in Section 11(b) hereof), the Purchase Price to be in effect after such
record date shall be determined by multiplying the Purchase Price in effect
immediately prior to such record date by a fraction, the numerator of which
shall be the then current per share market price of the Preferred Shares (as
such term is hereinafter defined) on such record date, less the fair market
value (as determined in good faith by the Board of Directors of the Company,
whose determination shall be described in a statement filed with the Rights
Agent) of the portion of the

                                       13
<PAGE>
 
assets or evidences of indebtedness so to be distributed or of such subscription
rights or warrants applicable to one Preferred Share and the denominator of
which shall be such current per share market price of the Preferred Shares;
provided, however, that in no event shall the consideration to be paid upon the
exercise of one Right be less than the aggregate par value of the shares of
capital stock of the Company to be issued upon exercise of one Right.  Such
adjustments shall be made successively whenever such a record date is fixed; and
in the event that such distribution is not so made, the Purchase Price shall
again be adjusted to be the Purchase Price which would then be in effect if such
record date had not been fixed.

     (d)  (i)  For the purpose of any computation hereunder, the "current per
share market price" of any security (a "Security" for the purpose of this
Section 11(d)(i)) on any date shall be deemed to be the average of the daily
closing prices per share of such Security for the 30 consecutive Trading Days
(as such term is hereinafter defined) immediately prior to such date; provided,
however, that in the event that the current per share market price of the
Security is determined during a period following the announcement by the issuer
of such Security of (A) a dividend or distribution on such Security payable in
shares of such Security or securities convertible into such shares, or (B) any
subdivision, combination or reclassification of such Security or securities
convertible into such shares, or (C) any subdivision, combination or
reclassification of such Security and prior to the expiration of 30 Trading Days
after the ex-dividend date for such dividend or distribution, or the record date
for such subdivision, combination or reclassification, then, and in each such
case, the current per share market price shall be appropriately adjusted to
reflect the current market price per share equivalent of such Security.  The
closing price for each day shall be the last sale price, regular way, or, in
case no such sale takes place on such day, the average of the closing bid and
asked prices, regular way, in either case as reported in the principal
consolidated transaction reporting system with respect to securities listed or
admitted to trading on the New York Stock Exchange or, if the Security is not
listed or admitted to trading on the New York Stock Exchange, as reported in the
principal consolidated transaction reporting system with respect to securities
listed on the principal national securities exchange on which the Security is
listed or admitted to trading or as reported on the Nasdaq National Market or,
if the Security is not listed or admitted to trading on any national securities
exchange or reported on the Nasdaq National Market, the last quoted price or, if
not so quoted, the average of the high bid and low asked prices in the over-the-
counter market, as reported by the National Association of Securities Dealers,
Inc. Automated Quotations System ("Nasdaq") or such other system then in use,
or, if on any such date the Security is not quoted by any such organization, the
average of the closing bid and asked prices as furnished by a professional
market maker making a market in the Security selected by the Board of Directors
of the Company or, if on any such date no professional market maker is making a
market in the Security, the price as determined in good faith by the Board of
Directors.  The term "Trading Day" shall mean a day on which the principal
national securities exchange on which the Security is listed or admitted to
trading is open for the transaction of business or, if the Security is not
listed or admitted to trading on any national securities exchange, a Business
Day.

          (ii) For the purpose of any computation hereunder, the "current per
share market price" of the Preferred Shares shall be determined in accordance
with the method set forth in Section 11(d)(i) hereof.  If the Preferred Shares
are not publicly traded, the "current per share market price" of the Preferred
Shares shall be conclusively deemed to be the current per

                                       14
<PAGE>
 
share market price of the Common Shares as determined pursuant to Section
11(d)(i) hereof (appropriately adjusted to reflect any stock split, stock
dividend or similar transaction occurring after the date hereof) multiplied by
one hundred.  If neither the Common Shares nor the Preferred Shares are publicly
held or so listed or traded, "current per share market price" shall mean the
fair value per share as determined in good faith by the Board of Directors of
the Company, whose determination shall be described in a statement filed with
the Rights Agent.

     (e) No adjustment in the Purchase Price shall be required unless such
adjustment would require an increase or decrease of at least one percent (1%) in
the Purchase Price; provided, however, that any adjustments which by reason of
this Section 11(e) are not required to be made shall be carried forward and
taken into account in any subsequent adjustment.  All calculations under this
Section 11 shall be made to the nearest cent or to the nearest one one-hundredth
of a Preferred Share or one ten-thousandth of any other share or security as the
case may be.  Notwithstanding the first sentence of this Section 11(e), any
adjustment required by this Section 11 shall be made no later than the earlier
of (i) three years from the date of the transaction which requires such
adjustment or (ii) the date of the expiration of the right to exercise any
Rights.

     (f) If as a result of an adjustment made pursuant to Section 11(a) hereof,
the holder of any Right thereafter exercised shall become entitled to receive
any shares of capital stock of the Company other than Preferred Shares,
thereafter the number of such other shares so receivable upon exercise of any
Right shall be subject to adjustment from time to time in a manner and on terms
as nearly equivalent as practicable to the provisions with respect to the
Preferred Shares contained in Sections 11(a) through 11(c) hereof, inclusive,
and the provisions of Sections 7, 9, 10, 13 and 14 hereof with respect to the
Preferred Shares shall apply on like terms to any such other shares.

     (g) All Rights originally issued by the Company subsequent to any
adjustment made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of one one-hundredths of a
Preferred Share purchasable from time to time hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.

     (h) Unless the Company shall have exercised its election as provided in
Section 11(i) hereof, upon each adjustment of the Purchase Price as a result of
the calculations made in Section 11(b) and Section 11(c) hereof, each Right
outstanding immediately prior to the making of such adjustment shall thereafter
evidence the right to purchase, at the adjusted Purchase Price, that number of
one one-hundredths of a Preferred Share (calculated to the nearest one one-
millionth of a Preferred Share) obtained by (i) multiplying (x) the number of
one one-hundredths of a Preferred Share covered by a Right immediately prior to
this adjustment by (y) the Purchase Price in effect immediately prior to such
adjustment of the Purchase Price and (ii) dividing the product so obtained by
the Purchase Price in effect immediately after such adjustment of the Purchase
Price.

     (i) The Company may elect on or after the date of any adjustment of the
Purchase Price to adjust the number of Rights, in substitution for any
adjustment in the number of one one-hundredths of a Preferred Share purchasable
upon the exercise of a Right.  Each of the Rights outstanding after such
adjustment of the number of Rights shall be exercisable for the

                                       15
<PAGE>
 
number of one one-hundredths of a Preferred Share for which a Right was
exercisable immediately prior to such adjustment.  Each Right held of record
prior to such adjustment of the number of Rights shall become that number of
Rights (calculated to the nearest one ten-thousandth) obtained by dividing the
Purchase Price in effect immediately prior to adjustment of the Purchase Price
by the Purchase Price in effect immediately after adjustment of the Purchase
Price.  The Company shall make a public announcement of its election to adjust
the number of Rights, indicating the record date for the adjustment, and, if
known at the time, the amount of the adjustment to be made.  This record date
may be the date on which the Purchase Price is adjusted or any day thereafter,
but, if the Right Certificates have been issued, shall be at least ten (10) days
later than the date of the public announcement.  If Right Certificates have been
issued, upon each adjustment of the number of Rights pursuant to this Section
11(i), the Company shall, as promptly as practicable, cause to be distributed to
holders of record of Right Certificates on such record date Right Certificates
evidencing, subject to Section 14 hereof, the additional Rights to which such
holders shall be entitled as a result of such adjustment, or, at the option of
the Company, shall cause to be distributed to such holders of record in
substitution and replacement for the Right Certificates held by such holders
prior to the date of adjustment, and upon surrender thereof, if required by the
Company, new Right Certificates evidencing all the Rights to which such holders
shall be entitled after such adjustment.  Right Certificates so to be
distributed shall be issued, executed and countersigned in the manner provided
for herein and shall be registered in the names of the holders of record of
Right Certificates on the record date specified in the public announcement.

     (j) Irrespective of any adjustment or change in the Purchase Price or the
number of one one-hundredths of a Preferred Share issuable upon the exercise of
the Rights, the Right Certificates theretofore and thereafter issued may
continue to express the Purchase Price and the number of one one-hundredths of a
Preferred Share which were expressed in the initial Right Certificates issued
hereunder.

     (k) Before taking any action that would cause an adjustment reducing the
Purchase Price below one one-hundredth of the then par value, if any, of the
Preferred Shares issuable upon exercise of the Rights, the Company shall take
any corporate action which may, in the opinion of its counsel, be necessary in
order that the Company may validly and legally issue fully paid and
nonassessable Preferred Shares at such adjusted Purchase Price.

     (l) In any case in which this Section 11 shall require that an adjustment
in the Purchase Price be made effective as of a record date for a specified
event, the Company may elect to defer until the occurrence of such event the
issuing to the holder of any Right exercised after such record date of the
Preferred Shares and other capital stock or securities of the Company, if any,
issuable upon such exercise on the basis of the Purchase Price in effect prior
to such adjustment; provided, however, that the Company shall deliver to such
holder a due bill or other appropriate instrument evidencing such holder's right
to receive such additional shares upon the occurrence of the event requiring
such adjustment.

     (m) The Company covenants and agrees that, after the Distribution Date, it
will not, except as permitted by Section 23 or Section 27 hereof, take (or
permit any Subsidiary to take) any action the purpose of which is to, or if at
the time such action is taken it is reasonably foreseeable that the effect of
such action is to, materially diminish or eliminate the benefits

                                       16
<PAGE>
 
intended to be afforded by the Rights.  Any such action taken by the Company
during any period after any Person becomes an Acquiring Person but prior to the
Distribution Date shall be null and void unless such action could be taken under
this Section 11(m) from and after the Distribution Date.

     (n) Anything in this Section 11 to the contrary notwithstanding, the
Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that it in its sole discretion shall determine to be advisable in
order that any consolidation or subdivision of the Preferred Shares, issuance
wholly for cash of any Preferred Shares at less than the current market price,
issuance wholly for cash of Preferred Shares or securities which by their terms
are convertible into or exchangeable for Preferred Shares, dividends on
Preferred Shares payable in Preferred Shares or issuance of rights, options or
warrants referred to hereinabove in Section 11(b), hereafter made by the Company
to holders of its Preferred Shares shall not be taxable to such stockholders.

     (o) In the event that at any time after the date of this Agreement and
prior to the Distribution Date, the Company shall (i) declare or pay any
dividend on the Common Shares payable in Common Shares or (ii) effect a
subdivision, combination or consolidation of the Common Shares (by
reclassification or otherwise than by payment of dividends in Common Shares)
into a greater or lesser number of Common Shares, then in any such case (A) the
number of one one-hundredths of a Preferred Share purchasable after such event
upon proper exercise of each Right shall be determined by multiplying the number
of one one-hundredths of a Preferred Share so purchasable immediately prior to
such event by a fraction, the numerator of which is the number of Common Shares
outstanding immediately before such event and the denominator of which is the
number of Common Shares outstanding immediately after such event, and (B) each
Common Share outstanding immediately after such event shall have issued with
respect to it that number of Rights which each Common Share outstanding
immediately prior to such event had issued with respect to it.  The adjustments
provided for in this Section 11(o) shall be made successively whenever such a
dividend is declared or paid or such a subdivision, combination or consolidation
is effected.

     (p) The exercise of Rights under Section 11(a)(ii) hereof shall only result
in the loss of rights under Section 11(a)(ii) hereof to the extent so exercised
and shall not otherwise affect the rights represented by the Rights under this
Agreement, including the rights represented by Section 13 hereof.

     SECTION 12.  CERTIFICATE OF ADJUSTED PURCHASE PRICE OR NUMBER OF SHARES.
Whenever an adjustment is made as provided in Sections 11 and 13 hereof, the
Company shall promptly (i) prepare a certificate setting forth such adjustment,
and a brief statement of the facts accounting for such adjustment, (ii) file
with the Rights Agent and with each transfer agent for the Common Shares or the
Preferred Shares a copy of such certificate and (iii) mail a brief summary
thereof to each holder of a Right Certificate in accordance with Section 25
hereof.  The Rights Agent shall be fully protected in relying on any such
certificate and on any adjustment therein contained and shall not be deemed to
have knowledge of any adjustment unless and until it shall have received such
certificate.

     SECTION 13.  CONSOLIDATION, MERGER OR SALE OR TRANSFER OF ASSETS OR EARNING
                  POWER.

     (a) In the event that, following the Shares Acquisition Date or, if a
Transaction is proposed, the Distribution Date, directly or indirectly (x) the
Company shall consolidate with, or merge with and into, any Interested
Stockholder, or if in such merger or consolidation all holders of Common Stock
are not treated alike, any other Person, (y) any Interested Person, or if in
such merger or consolidation all holders of Common Stock are not treated alike,
any other Person shall consolidate with the Company, or merge with and into the
Company, and the Company shall be the continuing or surviving corporation of
such merger (other than, in the case of either transaction described in (x) or
(y), a merger or consolidation which would result in all of the voting power
represented by the securities of the Company outstanding immediately prior
thereto continuing to represent (either by remaining outstanding or by being
converted into securities of the surviving entity) all of the voting power
represented by the securities of the Company or such surviving entity
outstanding immediately after such merger or consolidation and the holders of
such securities not having changed as a result of such merger or consolidation),
or (z) the Company shall sell, mortgage or otherwise transfer (or one or more of
its subsidiaries shall sell, mortgage or otherwise transfer), in one or more
transactions, assets or earning power aggregating more than fifty percent (50%)
of the assets or earning power of the Company and its subsidiaries (taken as a
whole) to any Interested Stockholder or Stockholders, or if in such transaction
all holders of Common Stock are not treated alike, any other Person, (other than
the Company or any Subsidiary of the Company in one or more transactions each of
which individually and the aggregate does not violate Section 13(d) hereof)
then, and in each such case, proper provision shall be made so that (i) each
holder of a Right, subject to Section 11(a)(ii) hereof, shall have the right to
receive, upon the exercise thereof at a price equal to the then current Purchase
Price multiplied by the number of one one-hundredths of a Preferred Share for
which a Right is then exercisable in accordance with the terms of this Agreement
and in lieu of Preferred Shares, such number of freely tradeable Common Shares
of the Principal Party (as such term is hereinafter defined), free and clear of
liens, rights of call or first refusal, encumbrances or other adverse claims, as
shall be equal to the result obtained by (A) multiplying the then current
Purchase Price by the number of one one-hundredths of a Preferred Share for
which a Right is then exercisable (without taking into account any adjustment
previously made pursuant to Section 11(a)(ii) hereof) and dividing that product
by (B) fifty percent (50%) of the then current per share market price of the
Common Shares of such Principal Party (determined pursuant to Section 11(d)
hereof) on the date of consummation of such consolidation, merger, sale or
transfer; (ii) such Principal Party shall thereafter be liable for, and shall
assume, by virtue of such consolidation, merger, sale or transfer, all the
obligations and duties of the Company pursuant to this Agreement; (iii) the term
"Company" shall thereafter be deemed to refer to such Principal Party, it being
specifically intended that the provisions of Section 11 hereof shall apply to
such Principal Party; and (iv) such Principal Party shall take such steps
(including, but not limited to, the reservation of a sufficient number of shares
of its Common Shares in accordance with Section 9 hereof) in connection with
such consummation as may be necessary to assure that the provisions hereof shall
thereafter be applicable, as nearly as reasonably may be, in relation to its
Common Shares thereafter deliverable upon the exercise of the Rights.

                                       18
<PAGE>
 
     (b)  "Principal Party" shall mean:

          (i) in the case of any transaction described in clause (x) or (y) of
the first sentence of Section 13(a) hereof, the Person that is the issuer of any
securities into which Common Shares are converted in such merger or
consolidation, and if no securities are so issued, the Person that is the other
party to the merger or consolidation (or, if applicable, the Company, if it is
the surviving corporation); and

          (ii) in the case of any transaction described in (z) of the first
sentence of Section 13(a) hereof, the Person that is the party receiving the
greatest portion of the assets or earning power transferred pursuant to such
transaction or transactions;

provided, however, that in any case, (1) if the Common Shares of such Person are
not at such time and have not been continuously over the preceding 12-month
period registered under Section 12 of the Exchange Act, and such Person is a
direct or indirect subsidiary or Affiliate of another Person the Common Shares
of which are and have been so registered, "Principal Party" shall refer to such
other Person; (2) if such Person is a subsidiary, directly or indirectly, or
Affiliate of more than one Person, the Common Shares of two or more of which are
and have been so registered, "Principal Party" shall refer to whichever of such
Persons is the issuer of the Common Shares having the greatest aggregate market
value; and (3) if such Person is owned, directly or indirectly, by a joint
venture formed by two or more Persons that are not owned, directly or
indirectly, by the same Person, the rules set forth in (1) and (2) above shall
apply to each of the chains of ownership having an interest in such joint
venture as if such party were a "subsidiary" of both or all of such joint
venturers and the Principal Parties in each such chain shall bear the
obligations set forth in this Section 13 in the same ratio as their direct or
indirect interests in such Person bear to the total of such interests.

     (c) The Company shall not consummate any such consolidation, merger, sale
or transfer unless the Principal Party shall have a sufficient number of
authorized Common Shares that have not been issued or reserved for issuance to
permit the exercise in full of the Rights in accordance with this Section 13 and
unless prior thereto the Company and each Principal Party and each other Person
who may become a Principal Party as a result of such consolidation, merger, sale
or transfer shall have (i) executed and delivered to the Rights Agent a
supplemental agreement providing for the terms set forth in paragraphs (a) and
(b) of this Section 13 and (ii) prepared, filed and had declared and remain
effective a registration statement under the Act on the appropriate form with
respect to the Rights and the securities exercisable upon exercise of the Rights
and further providing that, as soon as practicable after the date of any
consolidation, merger, sale or transfer of assets mentioned in paragraph (a) of
this Section 13, the Principal Party at its own expense will:

          (i)   cause the registration statement under the Act with respect to
the Rights and the securities purchasable upon exercise of the Rights on an
appropriate form to remain effective (with a prospectus at all times meeting the
requirements of the Act) until the Final Expiration Date;

                                       19
<PAGE>
 
          (ii)  use its best efforts to qualify or register the Rights and the
securities purchasable upon exercise of the Rights under the blue sky laws of
such jurisdictions as may be necessary or appropriate;

          (iii) list the Rights and the securities purchasable upon exercise of
the Rights on each national securities exchange on which the Common Shares were
listed prior to the consummation of the Business Combination or on the Nasdaq
National Market if the Common Shares were listed on the Nasdaq National Market
or, if the Common Shares were not listed on a national securities exchange or
the Nasdaq National Market prior to the consummation of the Business
Combination, on a national securities exchange or the Nasdaq National Market;
and

          (iv) deliver to holders of the Rights historical financial statements
for the Principal Party and each of its Affiliates which comply in all material
respects with the requirements for registration on Form 10 under the Exchange
Act.

The provisions of this Section 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers.

     (d) After the Distribution Date, the Company covenants and agrees that it
shall not (i) consolidate with, (ii) merge with or into, or (iii) sell or
transfer to, in one or more transactions, assets or earning power aggregating
more than fifty percent (50%) of the assets or earning power of the Company and
its subsidiaries taken as a whole, any other Person (other than a Subsidiary of
the Company in a transaction which does not violate Section 11(m) hereof), if
(x) at the time of or after such consolidation, merger or sale there are any
charter or bylaw provisions or any rights, warrants or other instruments or
securities outstanding, agreements in effect or any other action taken which
would diminish or otherwise eliminate the benefits intended to be afforded by
the Rights or (y) prior to, simultaneously with or immediately after such
consolidation, merger or sale, the stockholders of the Person who constitutes,
or would constitute, the "Principal Party" for purposes of Section 13(a) hereof
shall have received a distribution of Rights previously owned by such Person or
any of its Affiliates and Associates.  The Company shall not consummate any such
consolidation, merger, sale or transfer unless prior thereto the Company and
such other Person shall have executed and delivered to the Rights Agent a
supplemental agreement evidencing compliance with this Section 13(d).

     SECTION 14.  FRACTIONAL RIGHTS AND FRACTIONAL SHARES.

     (a) The Company shall not be required to issue fractions of Rights or to
distribute Right Certificates which evidence fractional Rights.  In lieu of such
fractional Rights, there shall be paid to the registered holders of the Right
Certificates with regard to which such fractional Rights would otherwise be
issuable, an amount in cash equal to the same fraction of the current market
value of a whole Right.  For the purposes of this Section 14(a), the current
market value of a whole Right shall be the closing price of the Rights for the
Trading Day immediately prior to the date on which such fractional Rights would
have been otherwise issuable.  The closing price for any day shall be the last
sale price, regular way, or, in case no such sale takes place on such day, the
average of the closing bid and asked prices, regular way, in either case as
reported in the principal consolidated transaction reporting system with respect
to securities listed or admitted to trading on the New York Stock Exchange or,
if the Rights are not listed or

                                       20
<PAGE>
 
admitted to trading on the New York Stock Exchange, as reported in the principal
consolidated transaction reporting system with respect to securities listed on
the principal national securities exchange on which the Rights are listed or
admitted to trading or as reported on the Nasdaq National Market or, if the
Rights are not listed or admitted to trading on any national securities exchange
or reported on the Nasdaq National Market, the last quoted price or, if not so
quoted, the average of the high bid and low asked prices in the over-the-counter
market, as reported by Nasdaq or such other system then in use or, if on any
such date the Rights are not quoted by any such organization, the average of the
closing bid and asked prices as furnished by a professional market maker making
a market in the Rights selected by the Board of Directors of the Company.  If on
any such date no such market maker is making a market in the Rights, the fair
value of the Rights on such date as determined in good faith by the Board of
Directors of the Company shall be used.

     (b) The Company shall not be required to issue fractions of Preferred
Shares (other than fractions which are integral multiples of one one-hundredth
of a Preferred Share) upon exercise of the Rights or to distribute certificates
which evidence fractional Preferred Shares (other than fractions which are
integral multiples of one one-hundredth of a Preferred Share).  Fractions of
Preferred Shares in integral multiples of one one-hundredth of a Preferred Share
may, at the election of the Company, be evidenced by depositary receipts;
provided, however, that holders of such depositary receipts shall have all of
the designations and the powers, preferences and rights, and the qualifications,
limitations and restrictions to which they are entitled as beneficial owners of
the Preferred Shares represented by such depositary receipts.  In lieu of
fractional Preferred Shares that are not integral multiples of one one-hundredth
of a Preferred Share, the Company shall pay to the registered holders of Right
Certificates at the time such Rights are exercised as herein provided an amount
in cash equal to the same fraction of the current market value of one Preferred
Share.  For the purposes of this Section 14(b), the current market value of a
Preferred Share shall be the current per share market price of the Preferred
Shares (as determined pursuant to the second sentence of Section 11(d)(i)
hereof) for the Trading Day immediately prior to the date of such exercise (or,
if not publicly traded, in accordance with Section 11(d)(ii) hereof).

     (c) Following the occurrence of one of the transactions or events specified
in Section 11 hereof giving rise to the right to receive Common Shares, capital
stock equivalents (other than Preferred Shares) or other securities upon the
exercise of a Right, the Company shall not be required to issue fractions of
Common Shares or units of such Common Shares, capital stock equivalents or other
securities upon exercise of the Rights or to distribute certificates which
evidence fractional Common Shares, capital stock equivalents or other
securities.  In lieu of fractional Common Shares, capital stock equivalents or
other securities, the Company shall pay to the registered holders of Right
Certificates at the time such Rights are exercised as herein provided an amount
in cash equal to the same fraction of the current market value of one Common
Share or unit of such Common Shares, capital stock equivalents or other
securities.  For purposes of this Section 14(c), the current market value shall
be the current per share market price (as determined pursuant to Section
11(d)(i) hereof) for the Trading Day immediately prior to the date of such
exercise and, if such capital stock equivalent is not traded, each such capital
stock equivalent shall have the value of one one-hundredth of a Preferred Share.

                                       21
<PAGE>
 
     (d) The holder of a Right by the acceptance of the Right expressly waives
his right to receive any fractional Rights or any fractional shares upon
exercise of a Right (except as provided above).

     SECTION 15.  RIGHTS OF ACTION.  All rights of action in respect of this
Agreement, excepting the rights of action given to the Rights Agent under
Sections 18 and 20 hereof, are vested in the respective registered holders of
the Right Certificates (and, prior to the Distribution Date, the registered
holders of the Common Shares) and any registered holder of any Right Certificate
(or, prior to the Distribution Date, of the Common Shares), without the consent
of the Rights Agent or of the holder of any other Right Certificate (or, prior
to the Distribution Date, of the Common Shares), may, in his own behalf and for
his own benefit, enforce, and may institute and maintain any suit, action or
proceeding against the Company to enforce, or otherwise act in respect of, his
right to exercise the Rights evidenced by such Right Certificate in the manner
provided in such Right Certificate and in this Agreement.  Without limiting the
foregoing or any remedies available to the holders of Rights, it is specifically
acknowledged that the holders of Rights would not have an adequate remedy at law
for any breach of this Agreement and will be entitled to specific performance of
the obligations under, and injunctive relief against actual or threatened
violations of the obligations of any Person subject to, this Agreement.  Holders
of Rights shall be entitled to recover the reasonable costs and expenses,
including attorneys fees, incurred by them in any action to enforce the
provisions of this Agreement.

     SECTION 16.  AGREEMENT OF RIGHT HOLDERS.  Every holder of a Right, by
accepting the same, consents and agrees with the Company and the Rights Agent
and with every other holder of a Right that:

     (a) prior to the Distribution Date, the Rights will be transferable only in
connection with the transfer of the Common Shares;

     (b) after the Distribution Date, the Right Certificates are transferable
(subject to the provisions of this Rights Agreement) only on the registry books
of the Rights Agent if surrendered at the principal office of the Rights Agent,
duly endorsed or accompanied by a proper instrument of transfer; and

     (c) the Company and the Rights Agent may deem and treat the person in whose
name the Right Certificate (or, prior to the Distribution Date, the associated
Common Shares certificate) is registered as the absolute owner thereof and of
the Rights evidenced thereby (notwithstanding any notations of ownership or
writing on the Right Certificates or the associated Common Shares certificate
made by anyone other than the Company or the Rights Agent) for all purposes
whatsoever, and neither the Company nor the Rights Agent shall be affected by
any notice to the contrary.

     SECTION 17.  RIGHT CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER.  No holder,
as such, of any Right Certificate shall be entitled to vote, receive dividends
or be deemed for any purpose the holder of the Preferred Shares or any other
securities of the Company which may at any time be issuable on the exercise of
the Rights represented thereby, nor shall anything contained herein or in any
Right Certificate be construed to confer upon the holder of any Right
Certificate, as

                                       22
<PAGE>
 
such, any of the rights of a stockholder of the Company or any right to vote for
the election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action, or to
receive notice of meetings or other actions affecting stockholders (except as
provided in Section 25 hereof), or to receive dividends or subscription rights,
or otherwise, until the Right or Rights evidenced by such Right Certificate
shall have been exercised in accordance with the provisions hereof.

     SECTION 18.  CONCERNING THE RIGHTS AGENT.  The Company agrees to pay to the
Rights Agent reasonable compensation for all services rendered by it hereunder
and, from time to time, on demand of the Rights Agent, its reasonable expenses
and counsel fees and other disbursements incurred in the administration and
execution of this Agreement and the exercise and performance of its duties
hereunder.  The Company also agrees to indemnify the Rights Agent for, and to
hold it harmless against, any loss, liability, or expense, incurred without
negligence, bad faith or willful misconduct on the part of the Rights Agent, for
anything done or omitted by the Rights Agent in connection with the acceptance
and administration of this Agreement, including the costs and expenses of
defending against any claim of liability in the premises.  The indemnity
provided herein shall survive the expiration of the Rights and the termination
of this Agreement. In no case will the Rights Agent be liable for special,
indirect, incidental or consequential loss or damage of any kind whatsoever
(including but not limited to lost profits), even if the Rights Agent has been
advised of the possibility of such loss or damage.

     The Rights Agent shall be protected and shall incur no liability for, or in
respect of any action taken, suffered or omitted by it in connection with, its
administration of this Agreement in reliance upon any Right Certificate or
certificate for the Preferred Shares or Common Shares or for other securities of
the Company, instrument of assignment or transfer, power of attorney,
endorsement, affidavit, letter, notice, direction, consent, certificate,
statement, or other paper or document believed by it to be genuine and to be
signed, executed and, where necessary, verified or acknowledged, by the proper
person or persons, or otherwise upon the advice of counsel as set forth in
Section 20 hereof.

     SECTION 19.  MERGER OR CONSOLIDATION OR CHANGE OF NAME OF RIGHTS AGENT.
Any corporation into which the Rights Agent or any successor Rights Agent may be
merged or with which it may be consolidated, or any corporation resulting from
any merger or consolidation to which the Rights Agent or any successor Rights
Agent shall be a party, or any corporation succeeding to the shareholder
services or corporate trust business of the Rights Agent or any successor Rights
Agent, shall be the successor to the Rights Agent under this Agreement without
the execution or filing of any paper or any further act on the part of any of
the parties hereto, provided that such corporation would be eligible for
appointment as a successor Rights Agent under the provisions of Section 21
hereof.  In case at the time such successor Rights Agent shall succeed to the
agency created by this Agreement any of the Right Certificates shall have been
countersigned but not delivered, any such successor Rights Agent may adopt the
countersignature of the predecessor Rights Agent and deliver such Right
Certificates so countersigned; and in case at that time any of the Right
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Right Certificates either in the name of the predecessor Rights
Agent or in the name of the successor Rights Agent; and in all such cases such
Right Certificates shall have the full force provided in the Right Certificates
and in this Agreement.

                                       23
<PAGE>
 
     In case at any time the name of the Rights Agent shall be changed and at
such time any of the Right Certificates shall have been countersigned but not
delivered, the Rights Agent may adopt the countersignature under its prior name
and deliver Right Certificates so countersigned; and in case at that time any of
the Right Certificates shall not have been countersigned, the Rights Agent may
countersign such Right Certificates either in its prior name or in its changed
name; and in all such cases such Right Certificates shall have the full force
provided in the Right Certificates and in this Agreement.

     SECTION 20.  DUTIES OF RIGHTS AGENT.  The Rights Agent undertakes the
duties and obligations imposed by this Agreement upon the following terms and
conditions, by all of which the Company and the holders of Right Certificates,
by their acceptance thereof, shall be bound:

     (a) The Rights Agent may consult with legal counsel of its choice (who may
be legal counsel for the Company), and the opinion of such counsel shall be full
and complete authorization and protection to the Rights Agent as to any action
taken or omitted by it in good faith and in accordance with such opinion.

     (b) Whenever in the performance of its duties under this Agreement the
Rights Agent shall deem it necessary or desirable that any fact or matter be
proved or established by the Company prior to taking or suffering any action
hereunder, such fact or matter (unless other evidence in respect thereof be
herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by any one of the Chairman of the Board, the
Chief Executive Officer, the President, the Chief Financial Officer, any Vice
President, the Treasurer or the Secretary of the Company and delivered to the
Rights Agent; and such certificate shall be full authorization to the Rights
Agent for any action taken or suffered in good faith by it under the provisions
of this Agreement in reliance upon such certificate.

     (c) The Rights Agent shall be liable hereunder to the Company and any other
Person only for its own negligence, bad faith or willful misconduct.

     (d) The Rights Agent shall not be liable for or by reason of any of the
statements of fact or recitals contained in this Agreement or in the Right
Certificates (except its countersignature thereof) or be required to verify the
same, but all such statements and recitals are and shall be deemed to have been
made by the Company only.

     (e) The Rights Agent shall not be under any responsibility in respect of
the validity of this Agreement or the execution and delivery hereof (except the
due execution hereof by the Rights Agent) or in respect of the validity or
execution of any Right Certificate (except its countersignature thereof); nor
shall it be responsible for any breach by the Company of any covenant or
condition contained in this Agreement or in any Right Certificate; nor shall it
be responsible for any change in the exercisability of the Rights (including the
Rights becoming void pursuant to Section 11(a)(ii) hereof) or any adjustment in
the terms of the Rights (including the manner, method or amount thereof)
provided for in Sections 3, 11, 13, 23 or 24 hereof, or the ascertaining of the
existence of facts that would require any such change or adjustment (except with
respect to the exercise of Rights evidenced by Right Certificates after receipt
of a certificate pursuant to Section 12 hereof describing such change or
adjustment); nor shall it by any act hereunder be deemed to make any
representation or warranty as to the authorization or

                                       24
<PAGE>
 
reservation of any Preferred Shares to be issued pursuant to this Agreement or
any Right Certificate or as to whether any Preferred Shares will, when issued,
be validly authorized and issued, fully paid and nonassessable.

     (f) The Company agrees that it will perform, execute, acknowledge and
deliver or cause to be performed, executed, acknowledged and delivered all such
further and other acts, instruments and assurances as may reasonably be required
by the Rights Agent for the carrying out or performing by the Rights Agent of
the provisions of this Agreement.

     (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from any
one of the Chairman of the Board, the Chief Executive Officer, the President,
the Chief Financial Officer, any Vice President, the Secretary or the Treasurer
of the Company, and to apply to such officers for advice or instructions in
connection with its duties, and it shall not be liable for any action taken or
suffered by it in good faith in accordance with instructions of any such officer
or for any delay in acting while waiting for those instructions.  Any
application by the Rights Agent for written instructions from the Company may,
at the option of the Rights Agent, set forth in writing any action proposed to
be taken or omitted by the Rights Agent with respect to its duties or
obligations under this Agreement and the date on and/or after which such action
shall be taken or omitted and the Rights Agent shall not be liable for any
action taken or omitted in accordance with a proposal included in any such
application on or after the date specified therein (which date shall not be less
than three business days after the date indicated in such application unless any
such officer shall have consented in writing to an earlier date) unless, prior
to taking or omitting any such action, the Rights Agent has received written
instructions in response to such application specifying the action to be taken
or omitted.

     (h) The Rights Agent and any stockholder, director, officer or employee of
the Rights Agent may buy, sell or deal in any of the Rights or other securities
of the Company or become pecuniarily interested in any transaction in which the
Company may be interested, or contract with or lend money to the Company or
otherwise act as fully and freely as though it were not Rights Agent under this
Agreement.  Nothing herein shall preclude the Rights Agent from acting in any
other capacity for the Company or for any other legal entity.

     (i) The Rights Agent may execute and exercise any of the rights or powers
hereby vested in it or perform any duty hereunder either itself or by or through
its attorneys or agents, and the Rights Agent shall not be answerable or
accountable for any act, default, neglect or misconduct of any such attorneys or
agents or for any loss to the Company resulting from any such act, default,
neglect or misconduct, provided reasonable care was exercised in the selection
and continued employment thereof.

     (j) No provision of this Agreement shall require the Rights Agent to expend
or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or in the exercise of its rights if
there shall be reasonable grounds for believing that repayment of such funds or
adequate indemnification against such risk or liability is not reasonably
assured to it.

                                       25
<PAGE>
 
     (k) If, with respect to any Right Certificate surrendered to the Rights
Agent for exercise or transfer, the certificate attached to the form of
assignment or form of election to purchase, as the case may be, has not been
executed, the Rights Agent shall not take any further action with respect to
such requested exercise of transfer without first consulting with the Company.

     SECTION 21.  CHANGE OF RIGHTS AGENT.  The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Agreement
upon 30 days' notice in writing mailed to the Company and to each transfer agent
for the Common Shares or Preferred Shares by registered or certified mail, and
to the holders of the Right Certificates by first-class mail.  The Company may
remove the Rights Agent or any successor Rights Agent upon 30 days' notice in
writing, mailed to the Rights Agent or successor Rights Agent, as the case may
be, and to each transfer agent for the Common Shares or Preferred Shares by
registered or certified mail, and to the holders of the Right Certificates by
first-class mail.  If the Rights Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor to
the Rights Agent.  If the Company shall fail to make such appointment within a
period of 30 days after giving notice of such removal or after it has been
notified in writing of such resignation or incapacity by the resigning or
incapacitated Rights Agent or by the holder of a Right Certificate (who shall,
with such notice, submit his Right Certificate for inspection by the Company),
then the registered holder of any Right Certificate may apply to any court of
competent jurisdiction for the appointment of a new Rights Agent.  Any successor
Rights Agent, whether appointed by the Company or by such a court, shall be
either (a) a corporation organized and doing business under the laws of the
United States or of any other state of the United States which is authorized
under such laws to exercise corporate trust or stock transfer powers and is
subject to supervision or examination by federal or state authority and which
has at the time of its appointment as Rights Agent a combined capital and
surplus of at least Fifty Million Dollars ($50,000,000) or (b) an affiliate of
such a corporation.  After appointment, the successor Rights Agent shall be
vested with the same powers, rights, duties and responsibilities as if it had
been originally named as Rights Agent without further act or deed; but the
predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose.  Not later
than the effective date of any such appointment the Company shall file notice
thereof in writing with the predecessor Rights Agent and each transfer agent for
the Common Shares or Preferred Shares, and mail a notice thereof in writing to
the registered holders of the Right Certificates.  Failure to give any notice
provided for in this Section 21, however, or any defect therein, shall not
affect the legality or validity of the resignation or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the case may be.

     SECTION 22.  ISSUANCE OF NEW RIGHT CERTIFICATES.  Notwithstanding any of
the provisions of this Agreement or of the Rights to the contrary, the Company
may, at its option, issue new Right Certificates evidencing Rights in such form
as may be approved by its Board of Directors to reflect any adjustment or change
in the Purchase Price and the number or kind or class of shares or other
securities or property purchasable under the Right Certificates made in
accordance with the provisions of this Agreement.  In addition, in connection
with the issuance or sale of Common Shares following the Distribution Date and
prior to the earlier of the Redemption Date and the Final Expiration Date, the
Company (a) shall with respect to Common

                                       26
<PAGE>
 
Shares so issued or sold pursuant to the exercise of stock options or under any
employee plan or arrangement in existence prior to the Distribution Date, or
upon the exercise, conversion or exchange of securities, notes or debentures
issued by the Company and in existence prior to the Distribution Date, and (b)
may, in any other case, if deemed necessary or appropriate by the Board of
Directors of the Company, issue Right Certificates representing the appropriate
number of Rights in connection with such issuance or sale; provided, however,
that (i) the Company shall not be obligated to issue any such Right Certificates
if, and to the extent that, the Company shall be advised by counsel that such
issuance would create a significant risk of material adverse tax consequences to
the Company or the Person to whom such Right Certificate would be issued, and
(ii) no Right Certificate shall be issued if, and to the extent that,
appropriate adjustment shall otherwise have been made in lieu of the issuance
thereof.

     SECTION 23.  REDEMPTION.

     (a) The Rights may be redeemed by action of the Board of Directors pursuant
to Section 23(b) hereof and shall not be redeemed in any other manner.

     (b)  (i)  The Board of Directors of the Company may, at its option, at any
time prior to the earlier of such time as any Person becoming an Acquiring
Person or the Final Expiration Date, redeem all but not less than all of the
then outstanding Rights at a redemption price of $0.001 per Right, appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof (such redemption price being hereinafter
referred to as the "Redemption Price"), and the Company may, at its option, pay
the Redemption Price in Common Shares (based on the "current per share market
price," as such term is defined in Section 11(d) hereof, of the Common Shares at
the time of redemption), cash or any other form of consideration deemed
appropriate by the Board of Directors.  The redemption of the Rights by the
Board of Directors may be made effective at such time, on such basis and subject
to such conditions as the Board of Directors in its sole discretion may
establish.  Notwithstanding anything contained in this Agreement to the
contrary, the Rights shall not be exercisable pursuant to Section 11(a)(ii)
hereof prior to the expiration or termination of the Company's right of
redemption under this Section 23(b)(i).

          (ii) In addition, the Board of Directors of the Company may, at its
option, at any time after the time a Person becomes an Acquiring Person and the
expiration of any period during which the holder of Rights may exercise the
rights under Section 11(a)(ii) hereof but prior to any event described in clause
(x), (y) or (z) of the first sentence of Section 13 hereof, redeem all but not
less than all of the then outstanding Rights at the Redemption Price (x) in
connection with any merger, consolidation or sale or other transfer (in one
transaction or in a series of related transactions) of assets or earning power
aggregating fifty percent (50%) or more of the assets or earning power of the
Company and its subsidiaries (taken as a whole) in which all holders of Common
Shares are treated alike and not involving (other than as a holder of Common
Shares being treated like all other such holders) an Interested Stockholder or a
Transaction Person or (y)(A) if and for so long as the Acquiring Person is not
thereafter the Beneficial Owner of fifteen percent (15%) or more of the then
outstanding Common Shares, and (B) at the time of redemption no other Persons
are Acquiring Persons.

                                       27
<PAGE>
 
     (c) Immediately upon the action of the Board of Directors of the Company
ordering the redemption of the Rights pursuant to Section 23(b) hereof, and
without any further action and without any notice, the right to exercise the
Rights will terminate and the only right thereafter of the holders of Rights
shall be to receive the Redemption Price.  The Company shall promptly give
public notice of any such redemption; provided, however, that the failure to
give, or any defect in, any such notice shall not affect the validity of such
redemption.  Within ten (10) days after such action of the Board of Directors
ordering the redemption of the Rights pursuant to Section 23(b) hereof, the
Company shall mail a notice of redemption to all the holders of the then
outstanding Rights at their last addresses as they appear upon the registry
books of the Rights Agent or, prior to the Distribution Date, on the registry
books of the transfer agent for the Common Shares, provided, however, that
failure to give, or any defect in, any such notice shall not affect the validity
of such redemption.  Any notice which is mailed in the manner herein provided
shall be deemed given, whether or not the holder receives the notice.  Each such
notice of redemption will state the method by which the payment of the
Redemption Price will be made.  Neither the Company nor any of its Affiliates or
Associates may redeem, acquire or purchase for value any Rights at any time in
any manner other than that specifically set forth in this Section 23 or in
Section 24 hereof, and other than in connection with the purchase of Common
Shares prior to the Distribution Date.

     (d) The Company may, at its option, discharge all of its obligations with
respect to any redemption of the Rights by (i) issuing a press release
announcing the manner of redemption of the Rights and (ii) mailing payment of
the Redemption Price to the registered holders of the Rights at their last
addresses as they appear on the registry books of the Rights Agent or, prior to
the Distribution Date, on the registry books of the transfer agent for the
Common Shares, and upon such action, all outstanding Right Certificates shall be
null and void without any further action by the Company.

     SECTION 24.  EXCHANGE.

     (a) The Board of Directors of the Company may, at its option, at any time
after any Person becomes an Acquiring Person, exchange all or part of the then
outstanding and exercisable Rights (which shall not include Rights that have
become void pursuant to the provisions of Section 11(a)(ii) hereof) for Common
Shares at an exchange ratio of one Common Share per Right, appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof (such exchange ratio being hereinafter referred
to as the "Exchange Ratio").  Notwithstanding the foregoing, the Board of
Directors shall not be empowered to effect such exchange at any time after any
Person (other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or any such Subsidiary, or any entity holding Common
Shares for or pursuant to the terms of any such plan), together with all
Affiliates and Associates of such Person, becomes the Beneficial Owner of fifty
percent (50%) or more of the Common Shares then outstanding.

     (b) Immediately upon the action of the Board of Directors of the Company
ordering the exchange of any Rights pursuant to Section 24(a) hereof and without
any further action and without any notice, the right to exercise such Rights
shall terminate and the only right thereafter of a holder of such Rights shall
be to receive that number of Common Shares equal to the number of such Rights
held by such holder multiplied by the Exchange Ratio.  The Company

                                       28
<PAGE>
 
shall promptly give public notice of any such exchange; provided, however, that
the failure to give, or any defect in, such notice shall not affect the validity
of such exchange.  The Company promptly shall mail a notice of any such exchange
to all of the holders of such Rights at their last addresses as they appear upon
the registry books of the Rights Agent; provided, however, that the failure to
give, or any defect in, such notice shall not affect the validity of such
exchange.  Any notice which is mailed in the manner herein provided shall be
deemed given, whether or not the holder receives the notice.  Each such notice
of exchange will state the method by which the exchange of the Common Shares for
Rights will be effected and, in the event of any partial exchange, the number of
Rights which will be exchanged.  Any partial exchange shall be effected pro rata
based on the number of Rights (other than Rights which have become void pursuant
to the provisions of Section 11(a)(ii) hereof) held by each holder of Rights.

     (c) In lieu of issuing Common Shares in accordance with Section 24(a)
hereof, the Company may, if a majority of the Board of Directors then in office
determines that such action is necessary or appropriate and not contrary to the
interests of the holders of Rights, elect to (and, in the event that there are
not sufficient treasury shares and authorized but unissued Common Shares to
permit any exchange of the Rights in accordance with Section 24(a) hereof, the
Company shall) take all such action as may be necessary to authorize, issue or
pay, upon the exchange of the Rights, cash (including by way of a reduction of
the Purchase Price), property, Common Shares, other securities or any
combination thereof having an aggregate value equal to the value of the Common
Shares which otherwise would have been issuable pursuant to Section 24(a)
hereof, which aggregate value shall be determined by a nationally recognized
investment banking firm selected by a majority of the Board of Directors then in
office.  For purposes of the preceding sentence, the value of the Common Shares
shall be determined pursuant to Section 11(d) hereof.  Any election pursuant to
this Section 24(c) by the Board of Directors must be made within 60 days
following the date on which the event described in Section 11(a)(ii) hereof
shall have occurred.  Following the occurrence on the event described in Section
11(a)(ii) hereof, a majority of the Board of Directors then in office may
suspend the exercisability of the Rights for a period of up to 60 days following
the date on which the event described in Section 11(a)(ii) hereof shall have
occurred to the extent that such directors have not determined whether to
exercise their rights of election under this Section 24(c).  In the event of any
such suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended.

     (d) The Company shall not be required to issue fractions of Common Shares
or to distribute certificates which evidence fractional Common Shares.  In lieu
of such fractional Common Shares, the Company shall pay to the registered
holders of the Right Certificates with regard to which such fractional Common
Shares would otherwise be issuable an amount in cash equal to the same fraction
of the current market value of a whole Common Share.  For the purposes of this
Section 24(d), the current market value of a whole Common Share shall be the
closing price of a Common Share (as determined pursuant to the second sentence
of Section 11(d)(i) hereof) for the Trading Day immediately after the date of
the first public announcement by the Company that an exchange is to be effected
pursuant to this Section 24.

     (e) The Company shall not be required to issue fractions of Preferred
Shares (other than fractions which are integral multiples of one one-hundredth
of a Preferred Share) upon

                                       29
<PAGE>
 
exchange of the Rights or to distribute certificates which evidence fractional
Preferred Shares (other than fractions which are integral multiples of one one-
hundredth of a Preferred Share).  Fractions of Preferred Shares in integral
multiples of one one-hundredth of a Preferred Share may, at the election of the
Company, be evidenced by depositary receipts; provided, however, that holders of
such depositary receipts shall have all of the designations and the powers,
preferences and rights, and the qualifications, limitations and restrictions to
which they are entitled as beneficial owners of the Preferred Shares represented
by such depositary receipts.  In lieu of fractional Preferred Shares that are
not integral multiples of one one-hundredth of a Preferred Share, the Company
shall pay to the registered holders of Right Certificates at the time such
Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market value of one Preferred Share.  For the purposes
of this Section 24(e), the current market value of a Preferred Share shall be
one hundred (100) times the closing price of a Common Share (as determined
pursuant to the second sentence of Section 11(d)(i) hereof) for the Trading Day
immediately after  the date of the first public announcement by the Company that
an exchange is to be effected pursuant to this Section 24.

     SECTION 25.  NOTICE OF CERTAIN EVENTS.

     (a) In case the Company shall propose (i) to pay any dividend payable in
stock of any class to the holders of its Preferred Shares or to make any other
distribution to the holders of its Preferred Shares (other than a regular
quarterly cash dividend), (ii) to offer to the holders of its Preferred Shares
rights or warrants to subscribe for or to purchase any additional Preferred
Shares or shares of stock of any class or any other securities, rights or
options, (iii) to effect any reclassification of its Preferred Shares (other
than a reclassification involving only the subdivision of outstanding Preferred
Shares), (iv) to effect any consolidation or merger into or with, or to effect
any sale or other transfer (or to permit one or more of its Subsidiaries to
effect any sale or other transfer), in one or more transactions, of fifty
percent (50%) or more of the assets or earning power of the Company and its
Subsidiaries (taken as a whole), to any other Person, (v) to effect the
liquidation, dissolution or winding up of the Company, or (vi) to declare or pay
any dividend on the Common Shares payable in Common Shares or to effect a
subdivision, combination or consolidation of the Common Shares (by
reclassification or otherwise than by payment of dividends in Common Shares),
then, in each such case, the Company shall give to each holder of a Right
Certificate, in accordance with Section 26 hereof, a notice of such proposed
action, which shall specify the record date for the purpose of such stock
dividend, or distribution of rights or warrants, or the date on which such
reclassification, consolidation, merger, sale, transfer, liquidation,
dissolution, or winding up is to take place and the date of participation
therein by the holders of the Common Shares and/or the Preferred Shares, if any
such date is to be fixed, and such notice shall be so given in the case of any
action covered by clause (i) or (ii) above at least ten (10) days prior to the
record date for determining holders of the Preferred Shares for purposes of such
action, and in the case of any such other action, at least ten (10) days prior
to the date of the taking of such proposed action or the date of participation
therein by the holders of the Common Shares and/or the Preferred Shares,
whichever shall be the earlier.

     (b) In case the event set forth in Section 11(a)(ii) hereof shall occur,
then the Company shall as soon as practicable thereafter give to each holder of
a Right Certificate, in accordance with Section 26 hereof, a notice of the
occurrence of such event, which notice shall

                                       30
<PAGE>
 
describe the event and the consequences of the event to holders of Rights under
Section 11(a)(ii) hereof.

     SECTION 26.  NOTICES.  Notices or demands authorized by this Agreement to
be given or made by the Rights Agent or by the holder of any Right Certificate
to or on the Company shall be sufficiently given or made if sent by first-class
mail, postage prepaid, addressed (until another address is filed in writing with
the Rights Agent) as follows:

               BEI Technologies, Inc.
               One Post Street, Suite 2500
               San Francisco, CA  94104

Subject to the provisions of Section 21 hereof, any notice or demand authorized
by this Agreement to be given or made by the Company or by the holder of any
Right Certificate to or on the Rights Agent shall be sufficiently given or made
if sent by first-class mail, postage prepaid, addressed (until another address
is filed in writing with the Company) as follows:

               ChaseMellon Shareholder Services, L.L.C.
               50 California Street, 10th Floor
               San Francisco, CA  94111-4624

Notices or demands authorized by this Agreement to be given or made by the
Company or the Rights Agent to the holder of any Right Certificate shall be
sufficiently given or made if sent by first-class mail, postage prepaid,
addressed to such holder at the address of such holder as shown on the registry
books of the Company.

     SECTION 27.  SUPPLEMENTS AND AMENDMENTS.  Prior to the Distribution Date,
the Company and the Rights Agent shall, if the Company so directs, supplement or
amend any provision of this Agreement without the approval of any holders of the
Rights.  From and after the Distribution Date, the Company and the Rights Agent
shall, if the Company so directs, from time to time supplement or amend any
provision of this Agreement without the approval of any holders of Right
Certificates in order to (i) cure any ambiguity, (ii) correct or supplement any
provision contained herein which may be defective or inconsistent with any other
provisions herein, or (iii) change any other provisions with respect to the
Rights which the Company may deem necessary or desirable; provided, however,
that no such supplement or amendment shall be made which would adversely affect
the interests of the holders of Rights (other than the interests of an Acquiring
Person or its Affiliates or Associates).  Any supplement or amendment adopted
during any period after any Person has become an Acquiring Person but prior to
the Distribution Date shall become null and void unless such supplement or
amendment could have been adopted by the Company from and after the Distribution
Date.  Any such supplement or amendment shall be evidenced by a writing signed
by the Company and the Rights Agent.  Upon delivery of a certificate from an
appropriate officer of the Company which states that the proposed supplement or
amendment is in compliance with the terms of this Section 27, the Rights Agent
shall execute such supplement or amendment unless the Rights Agent shall have
determined in good faith that such supplement or amendment would adversely
affect its interest under this Agreement.  Prior to the Distribution Date, the
interests of the holders of Rights shall be deemed coincident with the interests
of the holders of Common Shares.

     SECTION 28.  DETERMINATION AND ACTIONS BY THE BOARD OF DIRECTORS, ETC.  For
all purposes of this Agreement, any calculation of the number of Common Shares
outstanding at any particular time, including for purposes of determining the
particular percentage of such outstanding Common Shares or any other securities
of which any Person is the Beneficial Owner, shall be made in accordance with
the last sentence of Rule 13d-3(d)(1)(i) of the General Rules and Regulations
under the Exchange Act as in effect on the date of this Agreement.  The Board of
Directors of the Company shall have the exclusive power and authority to

granted to the Board, or the Company, or as may be necessary or advisable in the
administration of this Agreement, including without limitation, the right and
power to (i) interpret the provisions of this Agreement, and (ii) make all
determinations deemed necessary or advisable for the administration of this
Agreement (including a determination to redeem or not redeem the Rights or to
amend the Agreement).  All such actions, calculations, interpretations and

respect to the foregoing) which are done or made by the Board in good faith,
shall (x) be final, conclusive and binding on the Rights Agent and the holders
of the Rights, and (y) not subject the Board to any liability to the holders of
the Rights.

     SECTION 29.  SUCCESSORS.  All the covenants and provisions of this
Agreement by or for the benefit of the Company or the Rights Agent shall bind
and inure to the benefit of their respective successors and assigns hereunder.

be construed to give to any person or corporation other than the Company, the

or claim under this Agreement; but this Agreement shall be for the sole and
exclusive benefit of the Company, the Rights Agent and the registered holders of
the Right Certificates (and, prior to the Distribution Date, the Common Shares).

     SECTION 31.  SEVERABILITY.  If any term, provision, covenant or restriction
of this Agreement is held by a court of competent jurisdiction or other
authority to be invalid, void or unenforceable, the remainder of the terms,

force and effect and shall in no way be affected, impaired or invalidated.

     SECTION 32.  GOVERNING LAW.  This Agreement and each Right Certificate

                 SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

                                       OF

                             BEI TECHNOLOGIES, INC.

                        (Pursuant to Section 151 of the
                       Delaware General Corporation Law)


          BEI TECHNOLOGIES, INC., a corporation organized and existing under the
General Corporation Law of the State of Delaware (hereinafter called the
"Company"), hereby certifies that the following resolution was adopted by the
Board of Directors of the Corporation as required by Section 151 of the General
Corporation Law at a meeting duly called and held on September 11, 1997:

          RESOLVED, that pursuant to the authority granted to and vested in the
     Board of Directors of the Company in accordance with the provisions of its
     Certificate of Incorporation, the Board of Directors hereby creates a
     series of Preferred Stock, par value $.001 per share, of the Company and
     hereby states the designation and number of shares, and fixes the relative
     designations and the powers, preferences and rights, and the
     qualifications, limitations and restrictions thereof (in addition to the
     provisions set forth in the Certificate of Incorporation of the Company,
     which are applicable to the Preferred Stock of all classes and series), as
     follows:

          Series A Junior Participating Preferred Stock:

          SECTION 1.  DESIGNATION AND AMOUNT.  Two Hundred Thousand (200,000)
     shares of Preferred Stock, $.001 par value, are designated "Series A Junior
     Participating Preferred Stock" with the designations and the powers,
     preferences and rights, and the qualifications, limitations and
     restrictions specified herein (the "Junior Preferred Stock").  Such number
     of shares may be increased or decreased by resolution of the Board of
     Directors; provided, that no decrease shall reduce the number of shares of
     Junior Preferred Stock to a number less than the number of shares then
     outstanding plus the number of shares reserved for issuance upon the
     exercise of outstanding options, rights or warrants or upon the conversion
     of

                                      A-1
<PAGE>
 
     any outstanding securities issued by the Company convertible into Junior
     Preferred Stock.

          SECTION 2.  DIVIDENDS AND DISTRIBUTIONS.

          (A) Subject to the rights of the holders of any shares of any series
     of Preferred Stock (or any similar stock) ranking prior and superior to the
     Junior Preferred Stock with respect to dividends, the holders of shares of
     Junior Preferred Stock, in preference to the holders of Common Stock, par
     value $.001 per share (the "Common Stock"), of the Company, and of any
     other junior stock, shall be entitled to receive, when, as and if declared
     by the Board of Directors out of funds legally available for the purpose,
     quarterly dividends payable in cash on the first day of April, July,
     October and January in each year (each such date being referred to herein
     as a "Quarterly Dividend Payment Date"), commencing on the first Quarterly
     Dividend Payment Date after the first issuance of a share or fraction of a
     share of Junior Preferred Stock, in an amount per share (rounded to the
     nearest cent) equal to the greater of (a) $l.00 or (b) subject to the
     provision for adjustment hereinafter set forth, 100 times the aggregate per
     share amount of all cash dividends, and 100 times the aggregate per share
     amount (payable in kind) of all non-cash dividends or other distributions,
     other than a dividend payable in shares of Common Stock or a subdivision of
     the outstanding shares of Common Stock (by reclassification or otherwise),
     declared on the Common Stock since the immediately preceding Quarterly
     Dividend Payment Date or, with respect to the first Quarterly Dividend
     Payment Date, since the first issuance of any share or fraction of a share
     of Junior Preferred Stock.  In the event the Company shall at any time
     declare or pay any dividend on the Common Stock payable in shares of Common
     Stock, or effect a subdivision or combination or consolidation of the
     outstanding shares of Common Stock (by reclassification or otherwise than
     by payment of a dividend in shares of Common Stock) into a greater or
     lesser number of shares of Common Stock, then in each such case the amount
     to which holders of shares of Junior Preferred Stock were entitled
     immediately prior to such event under clause (b) of the preceding sentence
     shall be adjusted by multiplying such amount by a fraction, the numerator
     of which is the number of shares of Common Stock outstanding immediately
     after such event and the denominator of which is the number of shares of
     Common Stock that were outstanding immediately prior to such event.

          (B) The Company shall declare a dividend or distribution on the Junior
     Preferred Stock as provided in paragraph (A) of this Section immediately
     after it declares a dividend or distribution on the Common Stock (other
     than a dividend payable in shares of Common Stock); provided that, in the
     event no dividend or distribution shall have been declared on the Common
     Stock during the period between any Quarterly Dividend Payment Date and the
     next subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per
     share on the Junior Preferred Stock shall nevertheless be payable on such
     subsequent Quarterly Dividend Payment Date.

                                      A-2
<PAGE>
 
          (C) Dividends shall begin to accrue and be cumulative on outstanding
     shares of Junior Preferred Stock from the Quarterly Dividend Payment Date
     next preceding the date of issue of such shares, unless the date of issue
     of such shares is prior to the record date for the first Quarterly Dividend
     Payment Date, in which case dividends on such shares shall begin to accrue
     from the date of issue of such shares, or unless the date of issue is a
     Quarterly Dividend Payment Date or is a date after the record date for the
     determination of holders of shares of Junior Preferred Stock entitled to
     receive a quarterly dividend and before such Quarterly Dividend Payment
     Date, in either of which events such dividends shall begin to accrue and be
     cumulative from such Quarterly Dividend Payment Date.  Accrued but unpaid
     dividends shall not bear interest.  Dividends paid on the shares of Junior
     Preferred Stock in an amount less than the total amount of such dividends
     at the time accrued and payable on such shares shall be allocated pro rata
     on a share-by-share basis among all such shares at the time outstanding.
     The Board of Directors may fix a record date for the determination of
     holders of shares of Junior Preferred Stock entitled to receive payment of
     a dividend or distribution declared thereon, which record date shall be not
     more than 60 days prior to the date fixed for the payment thereof.

          SECTION 3.  VOTING RIGHTS.  The holders of shares of Junior Preferred
     Stock shall have the following voting rights:

          (A) Subject to the provision for adjustment hereinafter set forth,
     each share of Junior Preferred Stock shall entitle the holder thereof to
     100 votes on all matters submitted to a vote of the stockholders of the
     Company.  In the event the Company shall at any time declare or pay any
     dividend on the Common Stock payable in shares of Common Stock, or effect a
     subdivision or combination or consolidation of the outstanding shares of
     Common Stock (by reclassification or otherwise than by payment of a
     dividend in shares of Common Stock) into a greater or lesser number of
     shares of Common Stock, then in each such case the number of votes per
     share to which holders of shares of Junior Preferred Stock were entitled
     immediately prior to such event shall be adjusted by multiplying such
     number by a fraction, the numerator of which is the number of shares of
     Common Stock outstanding immediately after such event and the denominator
     of which is the number of shares of Common Stock that were outstanding
     immediately prior to such event.

          (B) Except as otherwise provided herein, in any other Certificate of
     Designation creating a series of Preferred Stock or any similar stock, or
     by law, the holders of shares of Junior Preferred Stock and the holders of
     shares of Common Stock and any other capital stock of the Company having
     general voting rights shall vote together as one class on all matters
     submitted to a vote of stockholders of the Company.

          (C) Except as set forth herein, or as otherwise provided by law,
     holders of Junior Preferred Stock shall have no special voting rights and
     their

                                      A-3
<PAGE>
 
     consent shall not be required (except to the extent they are entitled to
     vote with holders of Common Stock as set forth herein) for taking any
     corporate action.

          SECTION 4.  CERTAIN RESTRICTIONS.

          (A) Whenever quarterly dividends or other dividends or distributions
     payable on the Junior Preferred Stock as provided in Section 2 are in
     arrears, thereafter and until all accrued and unpaid dividends and
     distributions, whether or not declared, on shares of Junior Preferred Stock
     outstanding shall have been paid in full, the Company shall not:

               (i)   declare or pay dividends, or make any other distributions,
     on any shares of stock ranking junior (either as to dividends or upon
     liquidation, dissolution or winding up) to the Junior Preferred Stock;

               (ii)  declare or pay dividends, or make any other distributions,
     on any shares of stock ranking on a parity (either as to dividends or upon
     liquidation, dissolution or winding up) with the Junior Preferred Stock,
     except dividends paid ratably on the Junior Preferred Stock and all such
     parity stock on which dividends are payable or in arrears in proportion to
     the total amounts to which the holders of all such shares are then
     entitled;

               (iii) redeem or purchase or otherwise acquire for consideration
     shares of any stock ranking junior (either as to dividends or upon
     liquidation, dissolution or winding up) to the Junior Preferred Stock,
     provided that the Company may at any time redeem, purchase or otherwise
     acquire shares of any such junior stock in exchange for shares of any stock
     of the Company ranking junior (either as to dividends or upon dissolution,
     liquidation or winding up) to the Junior Preferred Stock; or

               (iv)  redeem or purchase or otherwise acquire for consideration
     any shares of Junior Preferred Stock, or any shares of stock ranking on a
     parity (either as to dividends or upon liquidation, dissolution or winding
     up) with the Junior Preferred Stock, except in accordance with a purchase
     offer made in writing or by publication (as determined by the Board of
     Directors) to all holders of such shares upon such terms as the Board of
     Directors, after consideration of the respective annual dividend rates and
     other relative rights and preferences of the respective series and classes,
     shall determine in good faith will result in fair and equitable treatment
     among the respective series or classes.

          (B) The Company shall not permit any subsidiary of the Company to
     purchase or otherwise acquire for consideration any shares of stock of the
     Company unless the Company could, under paragraph (A) of this Section 4,
     purchase or otherwise acquire such shares at such time and in such manner.

          SECTION 5.  REACQUIRED SHARES.  Any shares of Junior Preferred Stock
     purchased or otherwise acquired by the Company in any manner whatsoever
     shall

                                      A-4
<PAGE>
 
     be retired and canceled promptly after the acquisition thereof.  All such
     shares shall upon their cancellation become authorized but unissued shares
     of Preferred Stock and may be reissued as part of a new series of Preferred
     Stock subject to the conditions and restrictions on issuance set forth
     herein, in the Restated Certificate of Incorporation, or in any other
     Certificate of Designation creating a series of Preferred Stock or any
     similar stock or as otherwise required by law.

          SECTION 6.  LIQUIDATION, DISSOLUTION OR WINDING UP.  Upon any
     liquidation, dissolution or winding up of the Company, no distribution
     shall be made (1) to the holders of shares of stock ranking junior (either
     as to dividends or upon liquidation, dissolution or winding up) to the
     Junior Preferred Stock unless, prior thereto, the holders of shares of
     Junior Preferred Stock shall have received $100 per share, plus an amount
     equal to accrued and unpaid dividends and distributions thereon, whether or
     not declared, to the date of such payment, provided that the holders of
     shares of Junior Preferred Stock shall be entitled to receive an aggregate
     amount per share, subject to the provision for adjustment hereinafter set
     forth, equal to 100 times the aggregate amount to be distributed per share
     to holders of shares of Common Stock, or (2) to the holders of shares of
     stock ranking on a parity (either as to dividends or upon liquidation,
     dissolution or winding up) with the Junior Preferred Stock, except
     distributions made ratably on the Junior Preferred Stock and all such
     parity stock in proportion to the total amounts to which the holders of all
     such shares are entitled upon such liquidation, dissolution or winding up.
     In the event the Company shall at any time declare or pay any dividend on
     the Common Stock payable in shares of Common Stock, or effect a subdivision
     or combination or consolidation of the outstanding shares of Common Stock
     (by reclassification or otherwise than by payment of a dividend in shares
     of Common Stock) into a greater or lesser number of shares of Common Stock,
     then in each such case the aggregate amount to which holders of shares of
     Junior Preferred Stock were entitled immediately prior to such event under
     the proviso in clause (1) of the preceding sentence shall be adjusted by
     multiplying such amount by a fraction the numerator of which is the number
     of shares of Common Stock outstanding immediately after such event and the
     denominator of which is the number of shares of Common Stock that were
     outstanding immediately prior to such event.

          SECTION 7.  CONSOLIDATION, MERGER, ETC.  In case the Company shall
     enter into any consolidation, merger, combination or other transaction in
     which the shares of Common Stock are exchanged for or changed into other
     stock or securities, cash and/or any other property, then in any such case
     each share of Junior Preferred Stock shall at the same time be similarly
     exchanged or changed into an amount per share, subject to the provision for
     adjustment hereinafter set forth, equal to 100 times the aggregate amount
     of stock, securities, cash and/or any other property (payable in kind), as
     the case may be, into which or for which each share of Common Stock is
     changed or exchanged.  In the event the Company shall at any time declare
     or pay any dividend on the Common Stock payable in shares of Common Stock,
     or effect a subdivision or combination or consolidation of the outstanding
     shares of Common Stock (by reclassification or

                                      A-5
<PAGE>
 
     otherwise than by payment of a dividend in shares of Common Stock) into a
     greater or lesser number of shares of Common Stock, then in each such case
     the amount set forth in the preceding sentence with respect to the exchange
     or change of shares of Junior Preferred Stock shall be adjusted by
     multiplying such amount by a fraction, the numerator of which is the number
     of shares of Common Stock outstanding immediately after such event and the
     denominator of which is the number of shares of Common Stock that were
     outstanding immediately prior to such event.

          SECTION 8.  NO REDEMPTION.  The shares of Junior Preferred Stock shall
     not be redeemable.

          SECTION 9.  RANK.  The Junior Preferred Stock shall rank, with respect
     to the payment of dividends and the distribution of assets, junior to all
     series of any other class of the Company's Preferred Stock.

          SECTION 10.  AMENDMENT.  The Restated Certificate of Incorporation of
     the Company shall not be amended in any manner which would materially alter
     or change the powers, preferences or special rights of the Junior Preferred
     Stock so as to affect them adversely without the affirmative vote of the
     holders of at least two-thirds of the outstanding shares of Junior
     Preferred Stock, voting together as a single class.

     IN WITNESS WHEREOF, the undersigned have executed this certificate as of
September 11, 1997.

Associate or Affiliate who becomes a transferee after the Acquiring Person

     As provided in the Rights Agreement, the Purchase Price and the number of
one one-hundredths of a Preferred Share which may be purchased upon the exercise
of the Rights evidenced by this Right Certificate are subject to modification
and adjustment upon the happening of certain events.

     This Right Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, as amended from time to time, which terms,
provisions and conditions are hereby incorporated herein by reference and made a
part hereof and to which Rights Agreement reference is hereby made for a full

Right or Rights evidenced hereby (other than fractions which are integral
multiples of one one-hundredth of a Preferred Share, which may, at the election
of the Company, be evidenced by depositary receipts) but in lieu thereof a cash
payment will be made, as provided in the Rights Agreement.

     No holder of this Right Certificate shall be entitled to vote or receive
dividends or be deemed for any purpose the holder of the Preferred Shares or of
any other securities of the Company which may at any time be issuable on the
exercise hereof, nor shall anything contained in the Rights Agreement or herein
be construed to confer upon the holder hereof, as such, any of the rights of a
stockholder of the Company or any right to vote for the election of directors or
upon any matter submitted to stockholders at any meeting thereof, or to give or
withhold consent to any corporate action, or to receive notice of meetings or
other actions affecting stockholders (except as provided in the Rights
Agreement), or to receive dividends or subscription rights, or otherwise, until
