recommend TI Group's offer. These factors are more fully described in the
enclosed Schedule 14D-9. After careful consideration, our Board of Directors
unanimously recommends that you accept TI Group's offer and tender your shares
to TI Group.

     1. a copy of our Solicitation/Recommendation Statement on Schedule 14D-

Company.
 
   On behalf of the Board of Directors,

Item 1. Security and Subject Company.
 
   Walbro Corporation, a Delaware corporation (the "Company"), is the subject
company. The principal executive offices of the Company are located at 1227
Centre Road, Auburn Hills, Michigan 48326. The title of the class of equity
securities to which this Statement relates is the common stock, par value
$0.50 per share (the "Common Stock"), of the Company, including the associated
rights to purchase Series A Junior Participating Preferred Stock (the
"Rights") issued pursuant to the Rights Agreement, dated as of June 30, 1998,
as amended on April 27, 1999 (the "Rights Agreement"), between the Company and
Harris Trust and Savings Bank, as Rights Agent (the "Rights Agent").
References herein to the "Shares" mean shares of the Common Stock and shall,
unless the context requires otherwise, include the Rights.
 
Item 2. Tender Offer of the Bidder.
 
   The Offer. This Statement relates to a tender offer by TI Automotive
Systems, Inc., a Delaware corporation ("Offeror"), which is an indirect wholly
owned subsidiary of TI Group plc, a company organized under the laws of
England and Wales ("TI Group"), to purchase all of the outstanding Shares at a
purchase price of $20.00 per share, net to the seller in cash (the "Offer
Price"), upon the terms and subject to the conditions set forth in the Offer
to Purchase dated May 4, 1999 (the "Offer to Purchase") and the related Letter
of Transmittal (which together with the Offer to Purchase and any amendments
or supplements thereto constitute the "Offer"). The Offer is disclosed in the
Tender Offer Statement on Schedule 14D-1, dated May 4, 1999 (the "Schedule
14D-1") as filed by TI Group and Offeror with the Securities and Exchange
Commission. The Schedule 14D-1 indicates that the principal executive offices
of TI Group are located at 50 Curzon Street, London, W1Y 7PN, England and the
principal executive offices of Offeror are located at 375 Park Avenue -- Suite
222, New York, New York 10152.
 
   The Offer is being made pursuant to an Agreement and Plan of Merger among
Offeror, TI Group and the Company, dated as of April 27, 1999, as amended by
the First Amendment thereto dated May 3, 1999 (the "Merger Agreement"). A copy
of the Merger Agreement and the First Amendment thereto are filed as Exhibits
1 and 2, respectively, to this Solicitation/Recommendation Statement on
Schedule 14D-9 (this "Schedule 14D-9") and is incorporated herein by reference
in their entirety. Pursuant to the Merger Agreement, following the
consummation of the Offer, upon the satisfaction or waiver of certain
conditions, and in accordance with the Delaware General Corporation Law (the
"DGCL"), Offeror will be merged with and into the Company (the "Merger" and,
together with the Offer, the "Transaction"), with the Company surviving the
Merger (the Company following the Merger is sometimes referred to as the
"Surviving Corporation"). In the Merger, the holders of Shares as of the
effective time of the Merger will receive an amount in cash equal to the Offer
Price. The shares of common stock of Offeror outstanding immediately prior to
the Merger shall be converted into shares of Common Stock of the Surviving
Corporation.
 
Item 3. Identity and Background.
 
   (a) The name and business address of the Company, which is the person
filing this Statement, are set forth in Item 1 above, and incorporated herein
by reference.
 
   (b) Certain contracts, agreements, arrangements or understandings between
the Company or its affiliates and certain of its executive officers, directors
or affiliates are described in Annex A attached to this Schedule 14D-9 and
incorporated herein by reference.
 
Purpose of the Offer; Plans for the Company; the Merger.
 
   Purpose. The purpose of the Offer is to acquire for cash as many
outstanding Shares as possible as a first step in acquiring the entire equity
interest in the Company.
 
   If Offeror acquires over 50% of the outstanding Shares pursuant to the
Offer, it will have the vote necessary under Delaware law and the Company's
Restated Certificate of Incorporation to approve the Merger. Under the DGCL,
if Offeror owns at least 90% of the outstanding Shares, the Merger may be
effected without the vote of
<PAGE>
 
the Company's stockholders or the approval of the Company's Board of
Directors. Therefore, if at least approximately 7,819,465 Shares (or such
greater number as may be necessary if options are exercised) are acquired
pursuant to the Offer or otherwise, Offeror will be able to and intends to
effect the Merger without a meeting of holders of Shares.
 
The Merger Agreement
 
   The following summary of the Merger Agreement is qualified in its entirety
by reference to the Merger Agreement, a copy of which is filed as Exhibit 1 to
this Schedule 14D-9 and is incorporated herein by reference. The Merger
Agreement should be read in its entirety for a more complete description of
the matters summarized below.
 
   The Merger Agreement provides that upon the terms and subject to the
conditions set forth in the Merger Agreement and in accordance with the DGCL,
Offeror will be merged into the Company. Upon consummation of the Merger (the
"Effective Time"), each then outstanding Share (other than Shares held in the
Company's treasury or Shares beneficially owned by TI Group or Offeror or
Shares, if any, that are held by stockholders who properly exercise and
perfect appraisal rights pursuant to Section 262 of the DGCL), shall, by
virtue of the Merger and without any action on the part of the Company, TI
Group, Offeror or the holder thereof, be converted into the right to receive,
without interest, the Offer Price.
 
   Conditions to the Merger. The obligations of the Company, Offeror and TI
Group to effect the Merger are subject to the satisfaction of certain
conditions set forth in the Merger Agreement, including (i) the purchase by
Offeror, TI Group or their affiliates of Shares pursuant to the Offer, (ii)
the receipt of stockholder approval, if required, (iii) that no statute, rule
or regulation shall have been enacted or promulgated by any federal, state,
local or foreign court, arbitral tribunal, administrative agency or commission
or other governmental or regulatory authority or administrative agency (a
"Governmental Entity") which prohibits the consummation of the Merger, and
there shall be no order or injunction of a court of competent jurisdiction in
effect precluding consummation of the Merger, and (iv) that clearance from the
appropriate agencies pursuant to the HSR Act (as defined below) shall have
been obtained or the waiting period thereby shall have expired or been
terminated.
 
   Termination of the Merger Agreement. According to its terms, the Merger
Agreement may be terminated at any time prior to the Effective Time, whether
before or after approval of the Merger Agreement by the stockholders of the
Company, by the mutual consent of TI Group and the Company. In addition the
Merger Agreement may be terminated by either TI Group or the Company if (i)
(x) the Offer shall have expired without any Shares being purchased therein or
(y) Offeror shall not have accepted for payment all Shares tendered pursuant
to the Offer by September 30, 1999; provided that the right to terminate the
Merger Agreement under (x) or (y) is not available to any party whose failure
to fulfill any obligation under the Merger Agreement is the cause of, or
resulted in, the failure of TI Group or Offeror to purchase the Shares
pursuant to the Offer on or prior to such date or (ii) if any Governmental
Entity shall have issued an order, decree or ruling or taken any other action
which permanently restrains, enjoins or otherwise prohibits the acceptance for
payment of, or payment for, Shares pursuant to the Offer or Merger and such
order, decree, ruling or other action shall have become final and non-
appealable. The Merger Agreement may be terminated by TI Group if, among other
things, (i) prior to the purchase of Shares pursuant to the Offer, the Company
shall have breached any representation, warranty, covenant or other agreement
contained in the Merger Agreement (with certain exceptions) which (A) would
give rise to the failure of one of the conditions to the Offer which requires
the truth or performance thereof as of certain specified dates and (B) cannot
be or has not been cured, in all material respects, within 30 days after the
giving of written notice to the Company; (ii) if there has been a material
breach of the provisions of the Merger Agreement described below under "--
Acquisition Proposal" which, if capable of being cured, has not been cured
within 10 days; or (iii) if the Board of Directors of the Company has
withdrawn or modified in a manner adverse to TI Group or Offeror its approval
or recommendation of the Offer, the Merger Agreement or the Merger or the
Board of Directors of the Company has approved or recommended any Acquisition
Transaction (as defined below) or the Company shall have entered into any
agreement or agreement in principle with respect to any Acquisition
Transaction. The Merger Agreement may be terminated by the Company, among
other
 
                                       2
<PAGE>
 
reasons upon execution by it of a definitive agreement for a merger,
consolidation or other business combination involving the Company or any of
its subsidiaries or with respect to the acquisition of beneficial ownership of
all or any significant part of the assets or capital stock of the Company (an
"Acquisition Transaction"), that the Board of Directors of the Company shall
have decided to recommend to the Company's stockholders after it has
reasonably concluded, after consultation with its outside independent legal
counsel and a nationally recognized investment bank, that such transaction is
more favorable to the stockholders of the Company from a financial point of
view than the Offer and the Merger and that its failure to make such
recommendation and terminate the Merger Agreement could violate its fiduciary
duties under applicable law (a "Superior Proposal") provided (A) it has
complied with all provisions of the Merger Agreement governing conduct of the
Company with respect to offers or proposals for Acquisition Transactions,
including the notice provisions therein, (B) that it has paid or made
arrangement reasonably satisfactory to TI Group to pay promptly (and in any
event within five (5) business days of the termination of the Merger
Agreement) the Termination Expenses (as defined below) and (C) it shall have
provided to TI Group at least five (5) business days' prior written notice
that the Board intends to terminate the Merger Agreement, specifying the
material terms and conditions of such Acquisition Transaction. In connection
with the foregoing, the Company has agreed in the Merger Agreement that it
will (X) not enter into a binding agreement with respect to an Acquisition
Transaction until at least the sixth business day after it has provided the
notice to TI Group required by the Merger Agreement, (Y) consider in good
faith any offer made by TI Group during that period, and (Z) notify TI Group
promptly if its intention to enter into such an agreement shall change at any
time after such notification. The Company may also terminate the Merger
Agreement if TI Group or Offeror shall have breached in any material respect
any of their respective representations, warranties, covenants or other
agreements contained in the Merger Agreement, which breach cannot be or has
not been cured, in all material respects, within 30 days after the giving of
written notice to TI Group or Offeror, as applicable.
 
   Fees and Expenses. The Company shall immediately pay to TI Group (x) the
amount of $11.0 million and (y) all actual documented out-of-pocket expenses
reasonably incurred by TI Group and Offeror in connection with the Merger
Agreement and the Merger in an amount not to exceed $2.0 million (the
"Termination Expenses") if the Merger Agreement is terminated: (1) by the
Company if it executes an agreement for an Acquisition Transaction that it has
decided to recommend to the Company's stockholders after it has concluded that
such transaction constitutes a Superior Proposal, (2) by TI Group if (i) the
Board of Directors of the Company shall have withdrawn or modified in a manner
adverse to TI Group or Offeror its approval or recommendation of the Offer,
the Merger or the Merger Agreement, or approved or recommended any Acquisition
Transaction or (ii) the Company shall have entered into any agreement or
agreement in principle with respect to any Acquisition Transaction, if within
six (6) months after such termination an Acquisition Transaction shall be
consummated or (3) by either the Company or TI Group (if such party is
entitled to terminate the Merger Agreement pursuant to the terms thereof) if
(i) the Offer shall have expired without any Shares being purchased therein or
(ii) Offeror shall not have accepted for payment all Shares tendered pursuant
to the Offer by September 30, 1999 and (a) within six (6) months thereafter
there shall be publicly announced another Acquisition Transaction or prior
thereto any person shall have acquired beneficial ownership of at least 30% of
the outstanding Shares (the "Termination Date") and (b) an Acquisition
Transaction shall be consummated prior to the Termination Date or any person
shall have acquired beneficial ownership of at least 30% of the outstanding
Shares, as the case may be. In the event that the Merger Agreement is
terminated by TI Group due to a breach by the Company of the provisions
described below under "--Acquisition Proposal", the Company shall immediately
pay TI Group the Termination Expenses. In the event that the Company becomes
obligated to make the payment described in the preceding sentence and another
Acquisition Transaction is consummated within six (6) months after termination
by TI Group, the Company shall also pay to TI Group $11.0 million. The Company
shall immediately pay to TI Group the Termination Expenses if the Merger
Agreement is terminated by TI Group due to breach of any representation,
warranty, covenant or other agreement by the Company which cannot be or has
not been cured within 30 days of notice thereof if the breach thereof is due
solely to the Company's intentional or bad faith acts. Upon receipt of such
payments, TI Group shall not be entitled to and shall waive the right to seek
damages or other amounts or remedies from the Company for breach of, or
otherwise in connection with, the Merger Agreement other than in the case of
termination by TI Group as
 
                                       3
<PAGE>
 
described in the preceding sentence. If the Company fails to promptly pay such
amount, and, in order to obtain such payment, TI Group or Offeror commences a
suit which results in a judgment against the Company for the fee set forth
above, the Company shall pay to TI Group or Offeror its reasonable cost and
expenses (including reasonable attorneys' fees) in connection with such suit.
 
   Amendment of the Merger Agreement. Subject to the applicable provisions of
the DGCL, the Merger Agreement may be amended by written action taken by the
Company, TI Group and Offeror at any time prior to the Effective Time.
 
   Treatment of Convertible Trust Preferred Securities and Options. The Merger
Agreement also provides that each holder of an outstanding option, warrant or
commitment to purchase any capital stock or other equity interest of the
Company (other than holders of the Convertible Trust Preferred Securities of
Walbro Capital Trust (the "Preferred Securities")) (each, an "Option") shall
be entitled to receive at or after the Effective Time, upon surrender of such
option for cancellation, cash equal to the positive difference, if any,
between the Offer Price less the exercise price of each such Option multiplied
by the number of Shares covered by such Option. From and after the Effective
Time each holder of Preferred Securities shall have the right to convert its
Preferred Securities only into the amount of cash provided for by the terms of
the Preferred Securities after giving effect to any adjustment in the
conversion price provided for by such terms which is $26.40 per Preferred
Security. Upon consummation of the Merger, Parent will cause to be delivered
to each holder of Preferred Securities, the notice required by the terms of
the Indenture related thereto.
 
   Indemnification of Officers and Directors. The Merger Agreement provides
that from and after the Effective Time, the Surviving Corporation will cause
to be maintained in effect the Company's existing directors' and officers'
liability insurance for a period of six (6) years after the Effective Time;
provided the Surviving Corporation may substitute therefor other policies of
at least the same coverage amounts and which contain terms and conditions not
less advantageous (other than to a de minimus extent) to the beneficiaries of
the current policies, provided that such substitution may not result in any
gaps or lapses in coverage with respect to matters occurring prior to the
Effective Time; and provided further that the Surviving Corporation is not
required to pay an annual premium in excess of 200% of the last annual premium
paid by the Company prior to the date of the Merger Agreement and if the
Surviving Corporation is unable to obtain the required insurance, it is
required to obtain as much comparable insurance as possible for an annual
premium equal to such maximum amount. The Merger Agreement also provides that,
after the Effective Time, TI Group will indemnify each present and former
director or officer of the Company and each of its subsidiaries against all
losses, claims, damages, costs, expenses (including attorneys' fees and
expenses), liabilities or judgments, fines or amounts that are paid in
settlement as a result of or in connection with any threatened or actual
action, suit or proceeding based on or arising out of the fact that such
person is or was a director or officer of the Company or any of its
subsidiaries or out of or in connection with activities in such capacity,
whether pertaining to any matter existing or occurring at or prior to the
Effective Time and whether asserted or claimed prior to, or at or after, the
Effective Time ("Indemnified Liabilities"), including all Indemnified
Liabilities based on, or arising out of, or pertaining to, the Merger
Agreement or the transactions contemplated thereby, in each case to the
fullest extent a corporation is permitted to do so under the DGCL and to the
fullest extent provided in the by-laws or Certificate of Incorporation of the
Company and its subsidiaries in effect on the date of the Merger Agreement.
 
   Treatment of Employee Benefits. TI Group has agreed in the Merger Agreement
that, as soon as administratively practicable after the Effective Time, it
will cause all employees of the Company then actually at work to be covered
under employee benefit and fringe benefit plans that are no less favorable
than those that TI Group maintains for its similarly situated employees. TI
Group has also agreed that the Company will honor all obligations under
employee benefit plans and all employment agreements entered into by the
Company prior to the date of the Merger Agreement.
 
   Composition of the Board of Directors. The Merger Agreement provides that
promptly upon the purchase of and payment for any Shares by TI Group or any of
its subsidiaries which represents at least a majority of the outstanding
Shares (on a fully diluted basis), TI Group shall be entitled to designate
such number of directors, rounded up to the next whole number, on the Board of
Directors of the Company as is equal to the product of the total number of
directors on such Board (giving effect to the directors designated by TI Group
pursuant to
 
                                       4
<PAGE>
 
this sentence) multiplied by the percentage that the number of Shares so
accepted for payment bears to the total number of Shares then outstanding. In
furtherance thereof, the Company shall upon request of Offeror, promptly
either increase the size of its Board of Directors or secure the resignation
of such number of its incumbent directors, or both, as is necessary to enable
TI Group's designees to be so elected to the Company's Board, and shall take
all actions available to the Company to cause TI Group's designees to be so
elected. At such time, the Company shall, if requested by TI Group, also cause
persons designated by TI Group to constitute at least the same percentage
(rounded up to the next whole number) as is on the Company's Board of
Directors on each committee of the Company's Board of Directors. TI Group is
required to use its best efforts to cause the Company to have at least one
independent director until the Effective Time, including, but not limited to,
retaining one of the Company's current directors.
 
   Acquisition Proposal. The Company has agreed that neither it nor any of its
affiliates nor any of their respective directors, officers, employees, agents
or representatives shall, directly or indirectly, solicit or initiate or
knowingly facilitate or encourage (including by way of furnishing or
disclosing non-public information) any inquiries or the making of any proposal
with respect to an Acquisition Transaction, or negotiate, explore or otherwise
engage in discussions with any person (other than TI Group and its
representatives) with respect to any Acquisition Transaction or which may lead
to a proposal for an Acquisition Transaction, or enter into any agreement,
arrangement or understanding with respect to any such Acquisition Transaction
or which would require it to abandon, terminate or fail to consummate the
Merger or any other transaction contemplated by the Merger Agreement, or which
may cause the Board of Directors of the Company to withdraw, modify or amend
its recommendation that the Company's stockholders accept the Offer, tender
their Shares to Offeror or approve and adopt the Merger Agreement and the
Merger; provided, however, that the Company may, in response to a bona fide
unsolicited proposal from a third party regarding an Acquisition Transaction,
(x) furnish information to and engage in discussions and negotiations with
such third party (subject to such third party entering into a confidentiality
agreement with the Company containing terms substantially similar to the
Confidentiality Agreement between the Company and TI Group), but only if the
Board of Directors of the Company reasonably determines in good faith, after
consultation with its outside independent counsel and a nationally recognized
investment bank, that such unsolicited proposal could reasonably lead to a
Superior Proposal and that failing to take such action could violate the
Board's fiduciary duties under applicable law and (y) take and disclose to the
Company's stockholders any proposal, and make related filings with the SEC, as
required by Rule 14e-3 and 14d-9 under the Exchange Act.
 
   Covenants. The Merger Agreement also contains certain other restrictions as
to the conduct of business by the Company pending the Merger, as well as
representations and warranties of each of the parties customary in
transactions of this kind.
 
   Appraisal Rights. Holders of Shares do not have appraisal rights as a
result of the Offer. However, if the Merger is consummated, each holder of
Shares who has neither voted in favor of the Merger nor consented thereto in
writing will be entitled to an appraisal by the Delaware Court of Chancery of
the fair value of such holder's Shares, exclusive of any element of value
arising from the accomplishment or expectation of the Merger, together with a
fair rate of interest, if any, to be paid. In determining such fair value, the
Delaware Court of Chancery may consider all relevant factors. The value so
determined could be more or less than the consideration to be paid in the
Offer and the Merger. Any judicial determination of the fair value could be
based upon considerations other than or in addition to the market value of the
Shares, including, among other things, asset values and earning capacity.
 
   If any holder of Shares who demands appraisal under Section 262 of the DGCL
fails to perfect, or effectively withdraws or loses such holder's right to
appraisal as provided in the DGCL, the Shares of such stockholder will be
converted into the right to receive the Offer Price in accordance with the
Merger Agreement. A stockholder may withdraw his demand for appraisal by
delivery to TI Group of a written withdrawal of such holder's demand for
appraisal and acceptance of the Merger.

   The foregoing discussion is not a complete statement of law pertaining to
appraisal rights under the DGCL and is qualified in its entirety by the full
text of Section 262 of the DGCL.
 
   Failure to follow the steps required by Section 262 of the DGCL for
perfecting appraisal rights may result in the loss of such rights.
 
   Rights Agreement. Set forth below is a summary description of the Rights as
filed with the Company's Registration Statement on Form 8-A dated July 8, 1998
relating to the Rights:
 
   On June 24, 1998, the Board of Directors of the Company declared a dividend
of one Right for each outstanding share of Common Stock. The dividend was
payable on July 17, 1998 (the "Record Date") to the stockholders of record on
that 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 $.01 per share (each, a "Preferred Share"), of the
Company at a price of $45 per one one-hundredth of a Preferred Share (the
"Purchase Price"), subject to adjustment.
 
   The description and terms of the Rights are set forth in the Rights
Agreement.
 
   Until the earlier of (i) the close of business on the tenth day after the
first public announcement by the Company or an Acquiring Person (as defined
below) that a person or group of affiliated or associated persons have
acquired beneficial ownership of 15% or more of the outstanding Common Stock
(other than the Company, its majority-owned subsidiaries, and certain other
related persons ("Excluded Persons")) (an "Acquiring Person") (with certain
exceptions), or (ii) the close of business on 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) following the
commencement of, or the first public announcement of an intention to make, a
tender offer or exchange offer the consummation of which would result in the
beneficial ownership by such person or group (other than by Excluded Persons)
of 15% or more of such outstanding Common Stock (the earlier of such dates
being called the "Distribution Date"), the Rights will be evidenced by the
Common Stock certificates, will be transferable only by the transfer of the
Common Stock associated with such Rights and any transfer of the Common Stock
(including a transfer to the Company) will constitute a transfer of the
associated Rights.
 
   Until the Distribution Date (or earlier redemption or expiration of the
Rights), new Common Stock certificates issued after the Record Date, upon
transfer or new issuance of Common Stock, will contain a legend incorporating
the Rights Agreement by reference. Until the Distribution Date (or earlier
redemption or expiration of the Rights), the surrender for transfer of any
certificates for Common Stock outstanding as of the Record Date, even without
such notation will also constitute the transfer of the Rights associated with
the Common Stock represented by such certificate. As soon as practicable
following the Distribution Date, separate certificates evidencing the Rights
("Rights Certificates") will be mailed to holders of record of the Common
Stock as of the close of business on the Distribution Date and such separate
Rights Certificates alone will evidence the Rights.
 
   The Rights are not exercisable until the Distribution Date. The Rights will
expire on June 30, 2008 (the "Rights Expiration Date"), unless the Rights
Expiration Date is extended or unless the Rights are redeemed earlier by the
Company, in each case, as described below.
 
   If a person or group of affiliated or associated persons becomes an
Acquiring Person, each holder of a Right (other than those described in the
next sentence) will thereafter have the right to receive, upon exercise,
Common Stock (or, in certain circumstances, cash, property or other securities
of the Company) having a value equal to two times the Purchase Price of the
Right. All Rights that are, or (under certain circumstances specified in the
Rights Agreement) were, beneficially owned by any Acquiring Person will be
void.
 
                                       6

   At any time after the first date of public announcement by the Company or
an Acquiring Person than an Acquiring Person has become such (a "Shares
Acquisition Date"), if (i) the Company is the surviving corporation in a
merger with any other company or entity, (ii) the Company is acquired in a
merger or other business combination transaction, (iii) 50% or more of the
Company's consolidated assets or earning power are sold or (iv) an Acquiring
Person engages in certain "self-dealing" transactions with the Company, each
holder of an outstanding Right (other than those whose Rights have become
void) will thereafter have the right to receive, upon the exercise thereof at
the then current Purchase Price of the Right, that number of shares of common
stock of the surviving or acquiring company or the Acquiring Person, as the
case may be, which at the time of such transaction will have a market value of
two times the Purchase Price of such Right.
 
   At any time after a person or group becomes an Acquiring Person (other than
Excluded Persons), the Board of Directors of the Company may exchange the
Rights (other than Rights owned by an Acquiring Person which have become
void), in whole or in part, without any additional payment, for Common Stock
at an exchange ratio of one share of Common Stock (or of a share of a class or
series of the Company's preferred shares having equivalent rights, preferences
and privileges), per Right (subject to adjustment). The foregoing right of
exchange shall not be available at any time after any person or group and
their affiliates and associates (other than Excluded Persons) becomes the
beneficial owner of 50% or more of the Common Stock.
 
   The Purchase Price payable, and the number of Preferred Shares or other
securities or 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 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 or dividends
payable in Preferred Shares) or of subscription rights or warrants (other than
those referred to above). 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.
 
   At any time prior to the time that any person or group becomes an Acquiring
Person, the Board of Directors of the Company may redeem all, but not less
than all, of the Rights at a price of $.01 per Right (the "Redemption Price").
The redemption of the Rights may be made effective at such time, on such basis
and with such conditions, as the Board of Directors in its sole discretion may
establish. 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.
 
   Any of the provisions of the Rights may be amended by the Board of
Directors of the Company prior to the time that any person or group becomes an
Acquiring Person. After the time that any person or group becomes an Acquiring
Person, the provisions of the Rights Agreement may be amended by the Board in
order to make changes which do not adversely affect the interests of holders
of Rights (excluding the interests of any 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.
 
   On April 27, 1999, the Company amended the Rights Agreement (the "Rights
Agreement Amendment"), which renders the Rights Agreement inapplicable to the
Offer and the Merger by providing, among other things, that neither (a) the
announcement, commencement or consummation of the Offer nor (b) the execution,
delivery or performance of the Merger Agreement or the consummation of the
transactions contemplated thereby will (i) cause TI Group or any of its
affiliates to become an Acquiring Person, (ii) give rise to a Distribution
Date, a
 
                                       7
<PAGE>
 
Shares Acquisition Date or a Triggering Event or (iii) trigger certain other
events specified in the Rights Agreement. Except as expressly provided in the
Rights Agreement Amendment, the Rights Agreement remains in full force and
effect.
 
   Copies of the Merger Agreement and the Rights Agreement Amendment have been
filed as Exhibits to this Schedule 14D-9 and are incorporated herein by
reference. The foregoing descriptions of these documents are qualified in their
entireties by reference to such documents.

     (b) there shall be in effect any judgment, decree or order of any court
  or Governmental Entity, domestic or foreign, or any other legal restraint
  that:
 
       (i) makes illegal, or otherwise directly or indirectly restrains or
    prohibits the making of the Offer or the acceptance for payment or
    payment for some of or all the Shares pursuant to the Offer or the
    consummation of the Merger or that imposes or would impose upon the
    Company or TI Group or any of their respective subsidiaries or
    affiliates material damages in connection with the transactions

                                       8
<PAGE>
 
       (ii) restrains, prohibits or terminates the Company's or, as a
    result of the transactions contemplated by the Merger Agreement, TI
    Group's ownership, operation or lease (or that of their respective
    subsidiaries or affiliates) of any business, properties or assets which
    are material to the business or operation, as such business or
    operations are currently conducted, of the Company and its subsidiaries
    or of TI Group and its subsidiaries, as the case may be, or compels the
    Company or, as a result of the transactions contemplated by the Merger

     (c) there shall be any statute, rule, regulation, judgment, order or
  injunction enacted, entered, enforced, promulgated or issued or applicable

  in any of the consequences referred to in clauses (i) through (iv) of
  paragraph (a) above; or
 
     (d) there shall have occurred any events or state of circumstances after

  material adverse affect on the Company; or
 
     (e) (i) the Board of Directors of the Company shall have withdrawn or
  modified in a manner adverse to TI Group or Offeror its approval or
  recommendation of the Offer, the Merger or the Merger Agreement, approved
  or recommended any Acquisition Transaction, or (ii) the Company shall have
  entered into any agreement or agreement in principle with respect to any
  Acquisition Transaction; or
 
     (f) any of the representations or warranties of the Company set forth in
  the Merger Agreement that is qualified by materiality or material adverse
  affect shall not be true or any of the representations or warranties of the
  Company set forth in the Merger Agreement that is not so qualified shall
  not be true in any material respect, in each case (i) as of the date

  Group or Offeror to pay for the Company Common Stock;
 
which in the reasonable judgment of TI Group in any such case makes it
inadvisable to proceed with such acceptance for payment or payment.
 
                                       9

   The foregoing conditions are for the sole benefit of TI Group and Offeror,
may be asserted by TI Group or Offeror regardless of the circumstances giving
rise to such condition (including any action or inaction by TI Group or
Offeror not in violation of the Merger Agreement) and may be waived by TI
Group or Offeror in whole or in part at any time and from time to time in the
sole discretion of TI Group or Offeror, subject in each case to the terms of
the Merger Agreement. The failure by TI Group or Offeror at any time to
exercise any of the foregoing rights shall not be deemed a waiver of any such
right and each such right shall be deemed an ongoing right which may be
asserted at any time and from time to time.
 
   A public announcement shall be made of a material change in, or waiver of,
such conditions, and the Offer may, in certain circumstances, be extended in
connection with any such change or waiver.
 
Potential or Actual Conflicts of Interest
 
   Change of Control Agreements. On January 5, 1999, the Board amended the
Termination and Change of Control Agreements (the "TCOC Agreements") it has
with Frank E. Bauchiero, Michael A. Shope, Daniel L. Hittler, Robert H.
Walpole, Richard H. Whitehead, III, Michael Leopold, Andrew Masterman, Thomas
DeJong, and Melvin Todd (the "Senior Management Team") such that in the event
of a Change of Control during the calendar year 1999, (i) the single sum
payment equal to three times the employee's average compensation of the prior
three calendar years (including incentive bonus) is replaced by an amount
equal to three times the sum of (x) the employee's annual base salary and (y)
a bonus of 75% (100% for Frank E. Bauchiero) of such employee's annual base
salary, (ii) each employee is granted a 30-day period commencing six months
following consummation of a Change of Control (with the exception of Mr.
Bauchiero who is granted a 60-day period commencing two months following
consummation of a Change of Control) (the "TCOC Period"), during which the
employee will be entitled to voluntarily terminate employment with the Company
and be deemed to have terminated employment for good reason, and (iii) Mr.
Bauchiero will receive $2,000,000 in exchange for the cancellation of, or
failure to grant, the option to purchase 350,000 Shares scheduled to be
granted to him under his employment agreement. Because the Merger will
constitute a Change of Control under the TCOC Agreements, if all members of
the Senior Management Team exercise their right to voluntarily terminate
employment with the Company for good reason during the TCOC Period or such
members of the Senior Management Team were terminated by the Surviving
Corporation, the Surviving Corporation would be obligated to make payments in
an aggregate amount of approximately $10,000,000. Although not required to
continue their employment, the Senior Management Team intends to continue with
the Surviving Corporation after consummation of the Merger and consequently
may not be entitled to any payments under the TCOC Agreements.
 
   The amount payable to the employee under the TCOC Agreement is subject to
certain limitations set forth in the Internal Revenue Code. The preceding
discussion relating to the typical Amended TCOC Agreement is qualified in its
entirety by reference to the full text of the original TCOC Agreements filed
as Exhibits 8 through 12 to this Schedule 14D-9, and the text of the model
amendments filed as Exhibits 13 through 15 to this Schedule 14D-9.
 
   Vesting of Stock Options. All of the outstanding stock options to purchase
Shares granted by the Company under the Amended and Restated Walbro
Corporation Equity Based Long-Term Incentive Plan, and the Walbro Corporation
Broad-Based Long-Term Incentive Plan (collectively, the "Plans") immediately
vest and become exercisable if approved by the Committee (as that term is
defined therein) upon a "change of control." Pursuant to the Plans, the
Committee has approved the acceleration and the options covered by the Plans
will immediately vest and become exercisable and each individual will receive
the difference between $20.00 per share and the exercise price times the
number of options held and will be cashed out in the Merger. The Plans are
filed as Exhibits 16 and 17, respectively, to this Schedule 14D-9 and are
incorporated herein by reference.
 
   Except as described herein or incorporated herein by reference, to the
knowledge of the Company as of the date hereof, there are no contracts,
agreements, arrangements or understandings or any actual or potential
conflicts of interest between the Company or its affiliates and (i) the
Company, its executive officers, directors or affiliates or (ii) TI Group or
its executive officers, directors or affiliates.
 
Item 4. The Solicitation or Recommendation.
 
 (a) Recommendation
 
   The Board of Directors of the Company and a disinterested Committee of the
Board of Directors (as required by Section 203 of the DGCL) have unanimously
approved the Merger Agreement, the Offer and the
 
                                      10
<PAGE>
 
Merger and determined that the Offer and the Merger, are fair to, and in the
best interests of, the stockholders of the Company. The Board of Directors
recommends that all holders of Shares accept the Offer and tender their Shares
pursuant to the Offer. The Company expects that all directors will tender the
Shares they own to Offeror.
 
 (b)(i) Background
 
   In April 1998, Sir Christopher Lewinton, Chairman of the Board of Directors
of TI Group, approached Lambert Althaver, the then Chairman and Chief
Executive Officer of the Company, regarding a possible combination between TI
Group and the Company. Sir Christopher subsequently wrote to Mr. Althaver to
outline a non-binding proposal to commence discussions to acquire the Company
at $24.00 per Share. On April 17, 1998, Mr. Althaver resigned his position as
Chairman and Chief Executive Officer and was replaced by Frank E. Bauchiero.
On April 20, 1998, Mr. Bauchiero wrote back to Sir Christopher to reject the
approach, stating that the Company "is in good position to pursue its strategy
independently." Following receipt of Mr. Bauchiero's letter, Sir Christopher
wrote to Mr. Bauchiero and to each of the other directors of the Company
requesting an opportunity for him and William J. Laule, the Chief Executive
Officer of TI Group, to meet with the Board of the Company to explain TI
Group's proposal in detail. No such meeting took place.
 
   In June and July 1998, Sir Christopher and Mr. Bauchiero met in New York
and Detroit, respectively, to discuss the possibility of cooperative
opportunities for the two companies. No decisions were reached or actions
taken as a result of these meetings.
 
   During the Fall of 1998, the Board of Directors met to examine the impact
of short term and long term trends in the automobile manufacturing and
automobile component industries and the Company's short and long term
projected financial outlook. After these meetings the Board of Directors
authorized Mr. Bauchiero to pursue strategic alternatives, including a
possible sale of the Company. In October 1998, the Company engaged Salomon
Smith Barney Inc. ("Salomon Smith Barney") to act as its financial advisor to
assist the Company in its review of strategic alternatives. On November 3,
1998 the Company met with its legal and financial advisors to discuss
potential strategic alternatives, including a possible business combination,
and the timing of such alternatives.
 
   During November 1998, companies, including TI Group, were approached to
determine their level of interest regarding a possible business combination
transaction with the Company. From November 1998 through January 1999 several
of these companies conducted a preliminary due diligence review of certain
legal, financial and operating data of the Company. In January 1999 TI Group
entered into a confidentiality agreement with the Company and thereafter
received an information memorandum and certain other information regarding the
Company. During January 1999 a number of these entities, including TI Group,
submitted indications of interest to the Company and continued their due
diligence review of the Company.
 
   During February 1999 members of senior management of the Company met with
representatives of those entities which had submitted preliminary indications
of interest to discuss business issues and the structure and timing of a
potential business combination transaction.
 
   On March 1, 1999, Sir Christopher wrote to Mr. Bauchiero to identify a
number of areas that TI Group needed additional due diligence information
before it could consider making any proposal to the Board of Directors of the
Company. During early March 1999, the parties suspended negotiations,
primarily as a result of a disagreement with respect to the price and terms of
a potential transaction. On March 3, 1999, TI Group's Board of Directors
determined that TI Group was not in a position to pursue the possible
acquisition of the Company at that time as its representatives had not been
able to complete due diligence to TI Group's satisfaction and had not received
certain financial information it deemed necessary. On March 3, 1999, the
Company received a letter from Sir Christopher which restated TI Group's
position that it was unable to proceed with the transaction based on the
foregoing. During March 1999 Mr. Bauchiero met or talked by telephone with Sir
Christopher on numerous occasions to resume discussions regarding a business
combination transaction.
 
 
   After further review of the Company's financial information and further due
diligence, Sir Christopher and Mr. Laule wrote a letter to Mr. Bauchiero on
March 19, 1999, informing Mr. Bauchiero that TI Group was not prepared to
proceed at a price which would likely be attractive to the Company.
 
                                      11
<PAGE>
 
   On March 22, 1999, Sir Christopher, Mr. Laule and Mr. Bauchiero met to
further discuss the possibility of a business combination. On March 23, 1999,
Sir Christopher wrote a letter to Mr. Bauchiero expressing TI Group's desire
to structure a transaction acceptable to both parties and made a conditional
offer to purchase the assets of the fuel delivery systems business from the
Company. The Company determined that this conditional offer was not in the
best interests of its stockholders. After further discussions internally and
with Warburg Dillon Read LLC, and after receiving, among other things,
assurances from Mr. Bauchiero regarding the ability to obtain the desired
consents from the Company's joint venture partners, on April 5, 1999, TI Group
made a formal offer to purchase the Company in a letter to Mr. Bauchiero from
Sir Christopher.
 
     April 5, 1999
 
     Mr. Frank Bauchiero
     Walbro Corporation
     1227 Centre Road
     Auburn Hills, Michigan 48326
 
     Dear Mr. Bauchiero:
 
     TI Group plc ("TI") is pleased to submit this offer to
     Walbro's Board of Directors to acquire Walbro Corporation
     ("Walbro" or the "Company") in a transaction in which a wholly
     owned subsidiary of TI will make a cash tender offer for all
     the outstanding common stock of the Company at $20 per share
     in cash (the "Consideration"), to be followed by a merger in
     which all remaining shares of common stock will be converted
     into the right to receive the Consideration. This offer
     extends to all options validly exercisable prior to expiration
     of the offer and is based on the currently outstanding number
     of common shares of approximately 8.7 million and 0.8 million
     shares underlying existing options; the total consideration
     will not be increased to take into account any further shares
     or rights to shares that may be issued prior to completion.
 
     A mark-up of the draft Agreement and Plan of Merger (the
     "Agreement") indicating TI's proposed changes will be sent
     tomorrow by courier. Subject to finalization of the disclosure
     letter and any consequent required amendments to the
     Agreement, TI would be prepared to sign the Agreement as
     submitted. Our offer is not subject to any financing
     contingency and is capable of being met from existing cash
     resources and committed credit facilities.
 
     Entering into the Agreement will be conditional upon TI
     accomplishing the following three objectives which we have
     discussed and which should be achievable, under the direction
     of Bill Laule and you, in a two week period beginning on April
     8:
 
     1. Information must be readily available for review by TI's
        senior management covering the key contacts, including
        price and cost information, to confirm the profit and cash
        flow projections of Walbro's businesses. It is important we
        review these issues in face-to-face meetings between the
        senior management of Walbro and TI in Detroit and Europe as
        needed. Our team is prepared to begin these meetings on
        April 8, and continue through to April 16 to cover all
        issues if necessary. At least one representative of our
        team would like to visit your plants in Cass City and Caro,
        Michigan during this two-week period.
 
     2. Our second objective requires the prior receipt of
        irrevocable written consents satisfactory to TI from
        Walbro's principal joint venture partners to TI's
        acquisition of Walbro, and confirmation that Walbro's
        current ownership position in, and rights under, its
        material joint ventures will be unaffected by the
        acquisition. Such consents, or contract revisions if
        required, will also need to permit TI to integrate
 
                                      12
<PAGE>
 
        the combined fuel systems businesses of Bundy and Walbro in
        order to derive the full benefits of the combination of the
        businesses and to meet the needs of our customers on a
        global basis. We would expect to meet as soon as possible
        with the joint venture partners and the management of the
        joint ventures in Detroit, Italy and Japan to assure
        ourselves of this. Our team is prepared to proceed as soon
        as your office can schedule these meetings.
 
     3. It is important that we reach agreement on the continuity
        of Walbro's management, and assure ourselves that key
        members of your management will remain with the business on
        terms acceptable to all parties.
 
     It is our expectation that TI will be granted a reasonable
     period of exclusivity to complete the process. We have assumed
     that you will approve going forward with this process on
     Wednesday, April 7. This offer will expire at close of
     business on April 8 Eastern Daylight Time unless exclusivity
     is received. During such a period of exclusivity we would
     expect to complete these objectives referenced above and
     resolve any other outstanding issues. We believe that this
     should be achievable in a two week period if our respective
     teams work together to achieve this goal.
 
     Although this offer is made with the full knowledge of the
     Board of Directors of TI, entering into the definitive
     Agreement will be subject to the final approval of TI's Board
     at its meeting on April 21. The target date for a public
     announcement would be around April 28. The offer is also

     We very much appreciate the courtesies and cooperation we have
     received from the Company during the course of our review and

   On April 7, 1999, at the direction of the Company, representatives of
Salomon Smith Barney contacted representatives of Warburg Dillon Read to
indicate that the Company wished to proceed with TI Group's proposal and to
inquire what additional information regarding the Company TI Group required.
 
   On April 13 and 14, 1999, representatives of TI Group met or had telephonic
conferences with representatives of the Company to conduct further due
diligence, to discuss the terms of the transactions to be proposed to their
respective boards of directors and to negotiate definitive transaction
documents. Contacts between the representatives of TI Group and the Company,
and certain of the Company's joint venture partners continued over the next
two weeks.
 
   On April 19, 1999 the Board of Directors of the Company met in Chicago to
discuss the current state of negotiations with the TI Group. At this meeting,
Salomon Smith Barney presented an overview of the automotive OEM component
industry. Also at this meeting, Katten Muchin & Zavis, counsel to the Company,
presented a draft of the Merger Agreement, discussed its terms, conditions and
timing and discussed the issues for which no agreement had been reached with
TI Group. Representatives from Katten Muchin & Zavis also advised the Board
members of their fiduciary obligations in considering a potential business
combination transaction. Subsequent to these presentations, the Board
discussed the proposed transaction and certain open issues. After such
discussion, the Board directed senior management to continue negotiations with
TI Group and to attempt to resolve the remaining open issues. On Wednesday,
April 21, TI Group's Board met and approved in principle the transaction,
subject to the completion of the negotiation of an acceptable definitive
merger agreement, receipt of satisfactory consents from certain of the
Company's joint venture partners and final approval from a committee of TI
Group's Board consisting of Sir Christopher, Mr. Laule and Martin D. Angle.
 
   On April 24, 1999 the parties and their respective advisors met in London,
England to negotiate the terms of the Merger Agreement, which negotiations
continued until the early morning on April 25, 1999.
 
   On April 26, 1999, the Board of Directors of the Company held a telephonic
meeting, during which Mr. Bauchiero briefed the Board on the current status of
the negotiations and the Board held a discussion regarding certain unresolved
issues. Subsequent to this telephonic Board meeting, the Company and TI Group
and their respective representatives held a conference call to discuss certain
unresolved issues, authorization of the Merger Agreement and the transactions
contemplated thereby, and the timing of the announcement of the Merger.
 
   During the early evening of April 27, 1999, the Board of Directors of the
Company held a telephonic meeting during which Mr. Bauchiero briefed the Board
on what had taken place since the previous meeting. At this meeting, Salomon
Smith Barney made a financial presentation and delivered to the Board its
opinion as to the fairness, from a financial point of view, of the $20.00 per
Share cash consideration to be received in the Offer and the Merger by holders
of Shares (other than TI Group and its affiliates). The Company's counsel
reviewed the terms of the Merger Agreement and reminded the Board members of
their fiduciary duties as previously described at the meeting held on April
19, 1999. The Board asked senior management and the advisers a number of
questions regarding the terms, conditions and timing of the proposed
transaction. After a discussion, the Board of Directors unanimously approved,
among other things, the Merger Agreement and the transactions contemplated
thereby.
 
   The Merger Agreement was then executed and publicly announced on April 28,
1999, pursuant to a press release, a copy of which is attached hereto as
Exhibit 18.
 
                                      14

   On May 4, 1999, the Offeror commenced the Offer.
 
 (b)(ii) Reasons for the Recommendations
 
   Prior to approving the Merger Agreement and the transactions contemplated
thereby, the Board held meetings beginning in March 1999, and continuing on
April 18, 19, 26 and 27, 1999. At its meeting on April 19, 1999, the Board
considered presentations from, and reviewed the terms and conditions of the
Merger Agreement and the Transaction with senior executive officers of the
Company, and the Company's legal and financial advisors. At this meeting the
Board directed Mr. Bauchiero to continue negotiations with TI Group and,
subject to certain conditions, to attempt to finalize the Merger. At the April
27, 1999 meeting, the Board received final reports from senior management and
its legal and financial advisors, and approved the Merger Agreement. In
reaching the conclusions set forth in paragraph (a) above, the Board of
Directors of the Company considered a number of factors including, without
limitation, the following:
 
     (A) The consideration to be paid in the Offer and the Merger, and in
  particular the fact that the $20.00 per Share to be received by the
  Company's shareholders in the Offer and the Merger represents an
  approximate 111% premium over the average closing market price of $9.47 per
  Share for the period from March 26, 1999 through April 26, 1999 (the last
  trading day prior to the Board of Directors meeting referred to in
  paragraph (a) of this Item 4); and an approximate 70% premium over the
  closing market price of $11.75 per Share on April 26, 1999 (the day before
  the Merger Agreement was executed);
 
     (B) The Company's financial condition, results of operations, assets,
  liabilities, liquidity, business and prospects and industry, economic and
  market conditions, including the inherent risks and uncertainties in the
  Company's lines of business in each case on a historical, current and
  prospective basis;
 
     (C) The fact that the Company had seriously considered pursuing a
  transaction with TI Group because it believed that the two companies'
  strengths were complementary and that the combination of the two companies
  would permit the achievement of certain economies of scale and other
  synergies. The Board of Directors ultimately determined, after
  consideration of views of senior management, that in its view the
  combination of the two companies presented the best available means of
  achieving the greatest value for holders of its Shares;
 
     (D) TI Group's intent that after the Merger, the Company would be run as
  part of the combined TI Automotive Systems Group, an independent business
  unit of TI Group;
 
     (E) Management's analysis of the future prospects of the Company on a
  stand alone basis;
 
     (F) The historical and recent market prices for the Shares and potential
  future share prices;
 
     (G) The process undertaken by the Company to solicit third party
  indications of interest in the possible acquisition of, or business
  combination with, the Company;
 
     (H) The opinion of Salomon Smith Barney dated April 27, 1999 to the
  effect that, as of such date and based upon and subject to certain matters
  stated in such opinion, the $20.00 per Share cash consideration to be
  received in the Offer and the Merger by holders of Shares (other than TI
  Group and its affiliates) was fair, from a financial point of view, to such
  holders. The full text of Salomon Smith Barney's written opinion dated
  April 27, 1999, which sets forth the assumptions made, matters considered
  and limitations on the review undertaken by Salomon Smith Barney, is
  attached hereto as Annex B and is incorporated herein by reference. Salomon
  Smith Barney's opinion is directed only to the fairness, from a financial
  point of view, of the $20.00 per Share cash consideration to be received in
  the Offer and the Merger by holders of Shares (other than TI Group and its
  affiliates) and is not intended to constitute, and does not constitute, a
  recommendation as to whether any shareholder should tender Shares pursuant
  to the Offer. HOLDERS OF SHARES ARE URGED TO READ SUCH OPINION CAREFULLY IN
  ITS ENTIRETY;
 
     (I) The availability of appraisal rights under Section 262 of the DGCL;
 
     (J) The terms and conditions of the Merger Agreement, including
  provisions that (a) although prohibiting the Company and its
  representatives from soliciting or initiating submissions of Acquisition
 
                                       15
<PAGE>
 
  Proposals (as defined in the Merger Agreement), permit the Company and its
  representatives to furnish information to, negotiate and otherwise engage
  in discussions with, any third party in response to unsolicited proposals,
  to the extent the Board reasonably determines in good faith, after
  consultation with its outside independent counsel and a nationally
  recognized investment bank, that such unsolicited proposal could reasonably
  lead to a Superior Proposal (as defined in the Merger Agreement) or that
  the failure to do so could violate the fiduciary obligations of the Board,
  and (b) permit the Company to terminate the Merger Agreement to accept an
  alternative Acquisition Proposal, subject to payment of a termination fee
  of $11,000,000 plus reasonable expenses of TI Group and Offeror not to
  exceed $2,000,000;
 
     (K) The proposed structure of the Offer and the Merger involving an
  immediate cash tender offer followed by a merger for the same consideration
  and the fact that there is no financing or due diligence contingency to the
  Offer. In this connection, the Board also considered the likelihood that
  the proposed acquisition would be consummated, including the likelihood of
  satisfaction of the conditions to the Offer and the Merger contained in the
  Merger Agreement, and the risks to the Company if the acquisition were not
  consummated; and
 
     (L) The recommendation of the Company's management with respect to the
  proposed transaction.
 
   The Board evaluated the factors listed above in light of the directors'
knowledge of the business and operations of the Company and in their business
judgment. In view of the variety of factors considered by the Board in
connection with its evaluation of the Merger Agreement and the Transaction,
the Board did not find it practicable to and did not quantify or otherwise
assign relative weight to the specific factors considered in reaching its
determination. In addition, individual members of the Board may have given
different weights to different factors in making their individual
determinations.
 
Item 5. Persons Retained, Employed or to be Compensated.
 
   The Company has retained Salomon Smith Barney to act as its financial
advisor in connection with the Offer and the Merger. Pursuant to the terms of
Salomon Smith Barney's engagement, the Company has agreed to pay Salomon Smith
Barney an aggregate financial advisory fee based on a percentage of the
aggregate consideration, including liabilities assumed, payable in the Offer
and the Merger. It is currently estimated that the aggregate financial
advisory fee payable to Salomon Smith Barney will be approximately $6 million.
The Company also has agreed to reimburse Salomon Smith Barney for travel and
other out-of-pocket expenses, including the reasonable fees and disbursements
of its legal counsel, and to indemnify Salomon Smith Barney and related
parties against certain liabilities, including liabilities under the federal
securities laws, arising out of Salomon Smith Barney's engagement. Salomon
Smith Barney has in the past provided investment banking services to the
Company unrelated to the Offer and the Merger, for which services Salomon
Smith Barney has received compensation. In the ordinary course of business,
Salomon Smith Barney and its affiliates (including Citigroup Inc. and its
affiliates) may actively trade or hold the securities of the Company and TI
Group for their own account or for the account of customers and, accordingly,
may at any time hold a long or short position in such securities.
 
   Neither the Company nor any person acting on its behalf has employed,
retained or compensated any other person to make solicitations or
recommendations to security holders of the Company on its behalf concerning
the Offer.
 
Item 6. Recent Transactions and Intent with Respect to Securities.
 
   (a) To the best of the Company's knowledge, other than the transactions
disclosed in this Item 6, no transactions in Shares have been effected during
the past 60 days by the Company or by an executive officer, director,
affiliate or subsidiary of the Company.
 
   In the past 60 days options were issued to Messrs. Hittler, Whitehead,
Shope, Walpole and DeLong. On March 10, 1999, the Company granted 25,000
options to Daniel L. Hittler at a share exercise price of $9.75; 25,000
options to Richard Whitehead at a share exercise price of $9.75; 25,000
options to Mike Shope at a share
 
                                      16
<PAGE>
 
exercise price of $9.75; 15,000 options to Robert H. Walpole at a share
exercise price of $9.75; and 3,500 options to Thomas J. DeJong at a share
exercise price of $9.75 and 5,000 options to Thomas J. DeJong at a share
exercise price of $8.50. All of the aforementioned option grants were made
under the Company's Equity Based Long-Term Incentive Plan.
 
   (b) To the best of the Company's knowledge, all of its executive officers
and directors who own shares intend to tender pursuant to the Offer all Shares
which are owned beneficially or of record by such persons.
 
Item 7. Certain Negotiations and Transactions by the Subject Company.
 
   (a) Except as described under Item 3(b), the Company is not presently
engaged in any negotiation in response to the Offer which relates to or would
result in: (i) an extraordinary transaction such as a merger or reorganization
involving the Company or any subsidiary of the Company; (ii) a purchase, sale
or transfer of a material amount of assets by the Company or any subsidiary of
the Company; (iii) a tender offer for or other acquisition of securities by or
of the Company; or (iv) any material change in the present capitalization or
dividend policy of the Company.
 
   (b) Except as described in Item 4, there are no transactions, board
resolutions, agreements in principle or signed contracts in response to the
Offer which relate to or would result in one or more of the matters referred
to in paragraph (a) of this Item 7.
 
Item 8. Additional Information to be Furnished.
 
   Section 203 As a Delaware corporation, the Company is subject to Section
203 ("Section 203") of the DGCL. Section 203 would prevent an "Interested
Shareholder" (generally defined as a person beneficially owning 15% or more of
a corporation's voting stock) from engaging in a "Business Combination" (as
defined in Section 203) with a Delaware corporation for three years following
the date such person became an Interested Shareholder unless: (i) before such
person became an Interested Shareholder, the board of directors of the
corporation approved the transaction in which the Interested Shareholder
became an Interested Shareholder or approved the Business Combination, (ii)
upon consummation of the transaction which resulted in the Interested
Shareholder becoming an Interested Shareholder, the Interested Shareholder
owned at least 85% of the voting stock of the corporation outstanding at the
time the transaction commenced (excluding for purposes of determining the
number of shares of outstanding stock held by directors who are also officers
and by employee stock ownership plans that do not allow plan participants to
determine confidentially whether to tender shares), or (iii) following the
transaction in which such person became an Interested Shareholder, the
Business Combination is (x) approved by the board of directors of the
corporation and (y) authorized at a meeting of shareholders by the affirmative
vote of the holders of at least 66 2/3% of the outstanding voting stock of the
corporation not owned by the Interested Shareholder. In accordance with the
provisions of the Company's Restated Certificate of Incorporation and Section
203, the Board of Directors of the Company and a disinterested Committee of
the Board of Directors has approved the Merger Agreement and the Offeror's
acquisition of Shares pursuant to the Offer and the Merger and the
transactions contemplated thereby and, therefore, the restrictions of Section
203 are inapplicable to the Merger and the related transactions.
 
 United States Antitrust Compliance
 
   Under the HSR Act and the rules that have been promulgated thereunder by
the Federal Trade Commission (the "FTC"), certain acquisition transactions may
not be consummated unless certain information has been furnished to the
Antitrust Division of the United States Department of Justice (the "Antitrust
Division") and the FTC and certain waiting period requirements have been
satisfied. The acquisition of Shares by the Offeror pursuant to the Offer is
subject to such requirements.
 
   Pursuant to the requirements of the HSR Act, TI Group filed the required
Notification and Report Forms (the "Forms") with the Antitrust Division and
the FTC on April 30, 1999, and the Company filed the Forms with such agencies
on April 30, 1999. The statutory waiting period applicable to the purchase of
Shares pursuant
 
                                      17
<PAGE>
 
to the Offer is to expire at 11:59 P.M., New York City time, on Saturday, May
15, 1999. However, prior to such date, the Antitrust Division or the FTC may
extend the waiting periods by requesting additional information or documentary
material relevant to the acquisition. If such a request is made, the waiting
period will be extended until 11:59 P.M., New York City time, on the tenth day
after substantial compliance by the Offeror with such request. Thereafter,
such waiting periods can be extended only by court order. A request is being
made pursuant to the HSR Act for early termination of the applicable waiting
period. There can be no assurance, however, that the waiting period will be
terminated early. The Merger Agreement provides that, if by the expiration of
the Offer, the applicable waiting period under the HSR Act shall not have
expired or been terminated, Offeror shall, subject to the terms of the Merger
Agreement, extend the Offer from time to time until such waiting period has
expired or been terminated.
 
   The Antitrust Division and the FTC frequently scrutinize the legality of
transactions under U.S. antitrust laws. At any time before or after the
consummation of any such transactions, the Antitrust Division or the FTC
could, notwithstanding termination of the waiting period, take such action
under U.S. antitrust laws as it deems necessary or desirable in the public
interest, including seeking to enjoin the purchase of Shares pursuant to the
Offer or seeking divestiture of the Shares so acquired or divestiture of
substantial assets of the Offeror or the Company. Private parties may also
bring legal actions under the antitrust laws. There can be no assurance that a
challenge to the Offer on antitrust grounds will not be made, or if such a
challenge is made, what the result will be.
 
   European Antitrust Approval. Under Council Regulation (EEC) No. 4064/89,
the Offer and the Merger may not be consummated until the European Commission
has granted its approval thereof. TI Group expects to file the requisite
notification with respect to the Offer and the Merger with the European
Commission on May 7, 1999. Approval will be deemed granted upon it being
established, in terms satisfactory to Offeror, that it is not the intention of
the European Commission to initiate proceedings under Article 6(1)(c) of
Council Regulation (EEC) 4064/89 or to make a referral to a competent
authority under Article 9(1) thereof in connection with the proposed
acquisition of the Company by Offeror or any matter arising therefrom.
 
   Exon-Florio. Under Section 721 of Title VII of the United States Defense
Production Act of 1950, as amended by Section 5021 of the Omnibus Trade and
Competitiveness Act of 1988 ("Exon-Florio"), the President of the United
States is authorized to prohibit or suspend acquisitions, mergers or takeovers
by foreign persons of persons engaged in interstate commerce in the United
States if the President determines, after investigation, that such foreign
persons in exercising control of such acquired persons might take action that
threatens to impair the national security of the United States and that other
provisions of existing law do not provide adequate authority to protect
national security. Pursuant to Exon-Florio, notice of an acquisition by a
foreign person is to be made to the Committee on Foreign Investment in the
United States ("CFIUS"), which is comprised of representatives of the
Departments of the Treasury, State, Commerce, Defense and Justice, the Office
of Management and Budget, the United States Trade Representative's Office and
the Council of Economic Advisors and which has been selected by the President
to administer Exon-Florio, either voluntarily by the parties to such proposed
acquisition, merger or takeover or by any member of CFIUS.
 
   A determination that an investigation is called for must be made within 30
days after notification of a proposed acquisition, merger or takeover is first
filed with CFIUS. Any such investigation must be completed within 45 days of
such determination. Any decision by the President to take action must be
announced within 15 days of the completion of the investigation. Although
Exon-Florio does not require the filing of a notification, nor does it
prohibit the consummation of an acquisition, merger or takeover if
notification is not made, such an acquisition, merger or takeover thereafter
remains indefinitely subject to divestment should the President subsequently
determine that the national security of the United States has been threatened
or impaired. The Company has been informed by Offeror that Offeror does not
believe that the Offer or the Merger threatens to impair the national security
of the United States and that Offeror does not intend to notify CFIUS of the
proposed transaction.

                Information Statement Pursuant to Section 14(f)
                    of the Securities Exchange Act of 1934
                           And Rule 14f-1 Thereunder
 
General
 
   This Information Statement is being mailed on or about May 4, 1999 as part
of the Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule
14D-9") of Walbro Corporation (the "Company"). Capitalized terms used herein
and not otherwise defined shall have the meaning set forth in the Schedule
14D-9. You are receiving this Information Statement in connection with the
possible election of persons designated by TI Group (the "TI Group Designees")
to the Company's Board of Directors (the "Board"). The Merger Agreement
requires the Company, following the Offeror's purchase of Shares pursuant to
the Offer and upon request of Offeror, to take certain action to cause the TI
Group Designees to be elected to the Board. This Information Statement is
required by Section 14(f) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), and Rule 14f-1 promulgated thereunder. You are urged to
read this Information Statement carefully. You are not, however, required to
take any action in connection with this Information Statement.
 
   The Offer commenced on May 4, 1999 and is scheduled to expire at 12:00
midnight New York City time, on June 10, 1999 unless extended upon the terms
set forth in the Offer to Purchase.
 
   The information contained in this Information Statement concerning TI Group
and Offeror has been furnished to the Company by TI Group. The Company assumes
no responsibility for the accuracy or completeness of such information. To the
best knowledge of the Company, none of the TI Group Designees beneficially
owns any equity securities in the Company.
 
                           DESIGNATION OF DIRECTORS
 
   The Merger Agreement provides that, promptly upon the purchase of and
payment for any Company Common Stock by TI Group or any of its subsidiaries
which represents at least a majority of the outstanding Company Common Stock
(on a fully diluted basis), TI Group will be entitled to designate such number
of TI Group Designees rounded up to the next whole number, on the Board as is
equal to the product of the total number of directors on the Board (giving
effect to the directors designated by TI Group) multiplied by the percentage
that the number of Shares so accepted for payment bears to the total number of
Shares then outstanding. The Company has agreed, upon the request of TI Group,
to increase promptly the size of the Board or secure the resignations of such
number of its incumbent directors, or both, as is necessary to enable the TI
Group Designees to be so elected to the Board and shall take all actions
available to the Company to cause the TI Group Designees to be so elected. The
Company has also agreed upon request of TI Group to cause directors designated
by TI Group to constitute at least the same percentage (rounded up to the next
whole number) as such directors represent on the Board on each committee of
the Board. TI Group is required to use its best efforts to cause the Company
to have at least one independent director until the Effective Time, including,
but not limited to, retaining one of the Company's current directors.
 
   It is expected that the TI Group Designees will assume office promptly
following the purchase by TI Group of a majority of the outstanding Shares on
a fully diluted basis pursuant to the terms of the Offer, which purchase
cannot be earlier than June 10, 1999, and that, upon assuming office, the TI
Group Designees together with the continuing directors of the Company will
thereafter constitute the entire Board.

Director Compensation
 
   Employee-officers who are also Directors do not receive compensation for
their service as Directors. The non-employee Directors of the Company receive
an attendance fee of $1,200 for each Directors' meeting attended, $750 for
each committee meeting attended and $350 for each telephone meeting of the
full Board or a committee. Additionally, non-employee Directors of the Company
receive an annual retainer of $20,000.
 
   In addition, effective April 1, 1998, John E. Utley was awarded a
consulting contract related to his duties as Chairman of the Board. The
contract provides payment of $30,000 per year for services not to exceed 25
hours per month. Mr. Utley was elected Chairman of the Board effective May 20,
1998.
 
Meetings
 
   During the year ended December 31, 1998, the Board of Directors held eleven
formal meetings. Each of the Company's current directors attended at least 75%
of the aggregate of the total number of meetings held during 1998 by the Board
and the total number of meetings held during 1998 by Committees on which he
served.
 
Committees of the Board of Directors
 
   The Company has an Audit Committee, a Compensation Committee, an
Executive/Directors Committee and a Human Resource Planning Committee.
 
   The Audit Committee met twice in 1998 and recommended to the Board the
selection of the Company's independent public accountants and reviewed the
plan, scope and results of such independent public accountants' audit. The
primary purpose and function of the Audit Committee is to provide an
opportunity for direct communication with the Board by the Company's
independent public accountants.
 
   The Compensation Committee met four times in 1998. The Compensation
Committee awards stock options under the Company's stock option plans,
determines the compensation of the Company's executive officers and reviews,
and sets the policies for, the compensation payable to approximately the next
25 most highly compensated employees of the Company.
 
   The Executive/Directors Committee of the Board did not meet in 1998. The
Executive/Directors Committee is vested with the powers of the Board, except
those powers specifically reserved by Delaware law to the full Board. The
Executive/Directors Committee exists to give the Board the flexibility to make
decisions during intervals between regular meetings of the full Board. In
addition, the Executive/Directors Committee (i) conducts a continuing study of
the size, structure, and composition of the Board; (ii) seeks out and
interviews possible candidates and reports its recommendations to the Board;
(iii) periodically reviews the Board's tenure policy; and (iv) determines the
criteria for selection and retention of Board members. Although the Committee
has its own procedures for selecting nominees for Board membership, it will
give due consideration to nominees recommended by stockholders. A stockholder
desiring to recommend a person for nomination to the Board should submit a
complete resume of the proposed nominee's qualifications and background
together with a statement setting forth the reasons why such person should be
considered for membership. Such information should be addressed to the
Secretary of the Company.
 
   The Human Resources Planning Committee of the Board met once in 1998. The
Human Resource Planning Committee reviews the short and long range human
resource needs of the Company and advises management of its assessment. Also,
the Human Resource Planning Committee evaluates strategic human resource needs
including senior executive succession.
 
Section 16(a) Beneficial Ownership Reporting Compliance
 
   Section 16 of the Exchange Act requires the Company's officers, directors
and persons who own greater than 10% of a registered class of the Company's
equity securities to file reports of ownership and changes in
 
                                      A-4
<PAGE>
 
ownership with the Commission. Based solely on a review of the forms it has
received and on written representations from certain reporting persons that no
such forms were required for them, the Company believes that, except as set
forth below, during 1998 all Section 16 filing requirements applicable to its
officers, directors and 10% beneficial owners were complied with by such
persons.
 
   Dr. J. Dwane Baumgardner did not timely file on a Form 3 during 1997;
however, the information required was subsequently filed in 1998 on a Form 5.

Employment and Severance Agreements
 
   The Company has entered into employment agreements with Messrs. Hittler,
Shope, Whitehead and Walpole which have terms expiring on August 16, 1999 and
provides them minimum base salaries of $150,000, $150,000, $200,000 and
$265,000, respectively, subject to review and increase by the Board of
Directors Compensation Committee (the "Compensation Committee"). Each
employment agreement is renewable
 
                                      A-6
<PAGE>
 
automatically for twelve months, subject to cancellation by the Company prior
to the anniversary date. The Company also entered into an employment agreement
with Mr. Bauchiero which expires on December 31, 2001 and provides a base
salary of $450,000, subject to review and increase by the Compensation
Committee. Mr. Bauchiero, pursuant to his employment agreement, will also be
granted options to purchase 350,000 shares of Common Stock upon the approval
by the stockholders of the Amendment to the Equity Based Long-Term Incentive
Plan. The original Employment Agreements are filed as Exhibits 3 through 7 to
this Schedule 14D-9 and are incorporated herein by reference.
 
   For each of the executive officers, an employment agreement is linked to a
Termination and Change of Control Agreement ("COC Agreements"). In
combination, these agreements provide a severance provision under the terms of
which the employee is entitled to severance pay if during the initial term of
the agreement or a renewal term, his employment (i) is terminated (including
nonrenewal of his employment agreement) by the Company other than for cause or
(ii) is terminated voluntarily by him for good reason. The severance pay
payable under the agreements is an amount equal to the annual base
compensation being paid to the Named Officer at the date of termination.
 
   The employment agreements and the COC Agreements were the result of a
determination by the Board of Directors that it was important to, and in the
best interests of the Company and its stockholders, to ensure that in the
event of a possible change in control of the Company, the stability and
continuity of management will continue unimpaired, free of distraction
incident to any such change in control.
 
   The COC Agreements provide that if during a three-year period following a
Change in Control of the Company, an employee's employment is terminated by
the Company without cause or if the employee terminates employment for good
reason, the employee will receive (1) a single sum payment equal to three
times the employee's average compensation of the prior three calendar years
(including incentive bonus), (2) 36 months of additional medical, dental,
life, disability and accident insurance, (3) an amount equal to the actuarial
equivalent of the benefit under a SERP which the employee would receive if
employment would have continued for three years, (4) acceleration of any
performance awards granted prior to the extension date equal to the cash
amount payable plus the value of any shares of Common Stock payable upon
achievement of maximum performance, (5) a cash amount equal to the value of
any phantom shares of Common Stock credited to employee's deferral account,
(6) stock options will be fully exercisable and restricted stock will be
vested, (7) outplacement services at the sole discretion of employee and (8)
other perquisites substantially similar to those in effect for the employee at
the time of the Change of Control of the Company. In the event the present
value of these payments and benefits exceed an amount which would render them
"parachute payments" under Section 280G of the Internal Revenue Code, the
Company will pay a gross up amount to the employee to compensate him for the
additional excise tax assessed thereon. Each employee agrees that following
his termination of employment with the Company, he will cooperate with the
Company in any litigation involving the Company, not disclose Company trade
secrets, and for a one-year period following the date of such employee's
termination, not compete with the Company. "Change in Control" of the Company
is defined to include certain reorganizations, consolidations or mergers of
the Company, certain sales or transfers of substantially all the assets of the
Company, approval by the stockholders of the Company of its liquidation or
dissolution, a change in the composition of the Company's Board of Directors
such that it is comprised of directors, a majority of whom are not "Continuing
Directors" as defined in the agreements, or the acquisition by certain persons
of twenty percent or more of the combined voting power of the Company's
outstanding securities.

</TABLE>
 
   In general the SERP provides for an annual benefit of 1 1/2% of the Final
Average Earnings ("FAE") (generally defined as the average of the executive's
base salary for the three highest consecutive years of Company employment)
times the number of years of credited service. As of the end of the reporting
year, Frank E. Bauchiero is credited with 16.2 years of service; Robert H.
Walpole is credited with 28 years of service; Richard H. Whitehead, III is
credited with 18 years of service; Michael A. Shope is credited with 5 years
of service; and Daniel L. Hittler is credited with 13 years of service. The
annual benefit under the SERP is payable for a fixed period of ten years
(except for Frank E. Bauchiero whose SERP benefit is distributed in the form
of a single life annuity), beginning at age 65 if the executive previously
retired with a vested benefit, or at retirement (if the executive retires
after age 65); provided, however, that SERP benefits may be distributed as a
lump sum based on an interest rate discount assumption of 9.2% per annum
(except for Frank E. Bauchiero who would have a 7.2% interest rate discount
assumption). In the event the executive dies before benefit distribution under
the SERP commences, the SERP provides for a spousal benefit equal to 50% of
the amount of the retirement benefit which would have been paid to the
deceased executive had the benefit commenced to be paid the day before the
executive died. In the event the executive dies after benefit distribution
under the SERP commences, the SERP provides for a spousal benefit equal to 50%
of the balance of the deceased executive's retirement benefit, if any. Vesting
occurs after 5 years of service and attainment of age 60, upon Change of
Control, or upon such earlier date as provided in a specific employment
agreement. At the end of the reporting year, only Frank E. Bauchiero and
Daniel L. Hittler have a vested benefit under the SERP. Benefits listed in the
Pension Plan Table above are not subject to any deduction for Social Security
or other offset amounts.
 
   On January 5, 1999, subsequent to the reporting year, the Board
conditionally amended the SERP such that in the event of a Change of Control
during the calendar year 1999, (i) the executive's FAE under the SERP will
also include a bonus equal to 75% of the executive's base salary (except for
Frank E. Bauchiero who will receive a bonus equal to 100% of his base salary),
(ii) actuarial equivalency shall be based on an interest rate discount
assumption of 7.2% per annum (except for Frank E. Bauchiero who would have a
4.0% interest rate discount assumption), and (iii) the lump sum payment
determined on the basis of such interest rate discount assumption shall be
equal to the present value of a single life annuity if the executive is not
married, or a life and 50% surviving spouse annuity if the executive is
married, based on the 1983 Group Annuity Mortality Tables.
 
   Pursuant to the Plan and coincident with his retirement from the Company,
Mr. Althaver was awarded an annual payment of $196,695 for ten years to be
paid beginning September 1, 1998.

                   [LETTERHEAD OF SALOMON SMITH BARNEY INC.]
 
April 27, 1999
 
The Board of Directors
Walbro Corporation
1227 Centre Road
Auburn Hills, Michigan 48236
 
Members of the Board:
 
You have requested our opinion as to the fairness, from a financial point of
view, to the holders of the common stock of Walbro Corporation ("Walbro") of
the consideration to be received by such holders pursuant to the terms and
subject to the conditions set forth in the Agreement and Plan of Merger, dated
as of April 27, 1999 (the "Merger Agreement"), among TI Group plc ("TI
Group"), TI Automotive Systems, Inc., an indirect wholly owned subsidiary of
TI Group ("Merger Sub"), and Walbro. As more fully described in the Merger
Agreement, (i) Merger Sub will commence a tender offer to purchase all
outstanding shares of the common stock, par value $0.50 per share, of Walbro
(the "Walbro Common Stock") at a purchase price of $20.00 per share, net to
the seller in cash (the "Cash Consideration" and, such tender offer, the
"Tender Offer") and (ii) subsequent to the Tender Offer, Merger Sub will be
merged with and into Walbro (the "Merger" and, together with the Tender Offer,
the "Transaction") and each outstanding share of Walbro Common Stock not
previously tendered will be converted into the right to receive the Cash
Consideration.
 
In arriving at our opinion, we reviewed the Merger Agreement and held
discussions with certain senior officers, directors and other representatives
and advisors of Walbro and certain senior officers and other representatives
and advisors of TI Group concerning the business, operations and prospects of
Walbro. We examined certain publicly available business and financial
information relating to Walbro as well as certain financial forecasts and
other information and data for Walbro which were provided to or otherwise
discussed with us by the management of Walbro. We reviewed the financial terms
of the Transaction as set forth in the Merger Agreement in relation to, among
other things: current and historical market prices and trading volumes of
Walbro Common Stock; the historical and projected earnings and other operating
data of Walbro; and the capitalization and financial condition of Walbro. We
considered, to the extent publicly available, the financial terms of certain
other similar transactions recently effected which we considered relevant in
evaluating the Transaction and analyzed certain financial, stock market and
other publicly available information relating to the businesses of other
companies whose operations we considered relevant in evaluating those of
Walbro. In connection with our engagement, we were requested to approach, and
we held discussions with, third parties to solicit indications of interest in
the possible acquisition of all or a part of Walbro. In addition to the
foregoing, we conducted such other analyses and examinations and considered
such other information and financial, economic and market criteria as we
deemed appropriate in arriving at our opinion.
 
In rendering our opinion, we have assumed and relied, without independent
verification, upon the accuracy and completeness of all financial and other
information and data publicly available or furnished to or otherwise reviewed
by or discussed with us. With respect to financial forecasts and other
information and data provided to or otherwise reviewed by or discussed with
us, we have been advised by the management of Walbro that such forecasts and
other information and data were reasonably prepared on bases reflecting the
best currently available estimates and judgments of the management of Walbro
as to the future financial performance of Walbro. We have not made or been
provided with an independent evaluation or appraisal of the assets or
liabilities (contingent or otherwise) of Walbro nor have we made any physical
inspection of the properties or assets of Walbro. We express no view as to,
and our opinion does not address, the relative merits of the Transaction as
compared to any alternative business strategies that might exist for Walbro or
the effect of any other transaction in which Walbro might engage. Our opinion
is necessarily based upon information available to us, and financial, stock
market and other conditions and circumstances existing and disclosed to us, as
of the date hereof.

Salomon Smith Barney Inc. has acted as financial advisor to Walbro in
connection with the proposed Transaction and will receive a fee for such
services, a significant portion of which is contingent upon the consummation
of the Transaction. We also will receive a fee upon the delivery of this
opinion. We have in the past provided investment banking services to Walbro
unrelated to the proposed Transaction, for which services we have received
compensation. In the ordinary course of our business, we and our affiliates
may actively trade or hold the securities of Walbro and TI Group for our own
account or for the account of our customers and, accordingly, may at any time
hold a long or short position in such securities. In addition, we and our
affiliates (including Citigroup Inc. and its affiliates) may maintain
relationships with Walbro, TI Group and their respective affiliates.
 
Our advisory services and the opinion expressed herein are provided for the
information of the Board of Directors of Walbro in its evaluation of the
proposed Transaction, and our opinion is not intended to be and does not
constitute a recommendation to any stockholder as to whether such stockholder
should tender shares of Walbro Common Stock in the Tender Offer or how such
stockholder should vote on any matters relating to the proposed Transaction.
 
Based upon and subject to the foregoing, our experience as investment bankers,
our work as described above and other factors we deemed relevant, we are of
the opinion that, as of the date hereof, the Cash Consideration to be received
in the Transaction by the holders of Walbro Common Stock (other than TI Group
and its affiliates) is fair, from a financial point of view, to such holders.
 
Very truly yours,
 
/s/ Salomon Smith Barney Inc.

                                   THE MERGER

     2.1  The Offer.

          (a)  As promptly as practicable (but in no event later than five
business days after the public announcement of the execution hereof), Merger Sub
shall commence (within the meaning of Rule 14d-2 under the Securities Exchange
Act of 1934, as amended, and the rules and regulations promulgated thereunder
(collectively, the "Exchange Act")) a tender offer (the "Offer") for all of the
outstanding shares of Company Common Stock (including the Company Preferred
Rights) at a price of $20 per share of Company Common Stock, net to the seller
in cash (such price, or any such higher price per share as may be paid in the
Offer, being referred to herein as the "Offer Price"), subject to there being
validly tendered and not withdrawn prior to the expiration of the Offer, that
number of shares of Company Common Stock (excluding shares of Company Common
Stock held in the Company's treasury) which represents at least a majority of
the Company Common Stock outstanding on a Fully Diluted Basis (the "Minimum
Condition") and to the other conditions set forth in Annex A hereto, and shall
consummate the Offer in accordance with its terms ("Fully Diluted Basis" means
issued and outstanding Company Common Stock and Company Common Stock subject to
issuance under the Existing Options). The obligations of Merger Sub to accept
for payment and to pay for any Company Common Stock validly tendered on or prior
to the expiration of the Offer and not withdrawn shall be subject only to the
Minimum Condition and the other conditions set forth in Annex A hereto. The
Offer shall be made by means of an offer to purchase (the "Offer to Purchase")
containing the terms set forth in this Agreement, the Minimum Condition and the
other conditions set forth in Annex A hereto. Merger Sub shall not amend or
waive the Minimum Condition and shall not decrease the Offer Price or decrease
the number of shares of Company Common Stock sought, or amend any other
condition of the Offer in any manner adverse to the holders of the Company
Common Stock without the prior written consent of the Company; provided,
however, that if on the initial scheduled expiration date of the Offer which
shall be twenty business days after the date the Offer is commenced, the sole
condition remaining unsatisfied is the failure of the waiting period under the
HSR Act to have expired or been terminated, Merger Sub shall extend the
expiration date from time to time until two business days after the expiration
of the waiting period under the HSR Act. Merger Sub shall, on the terms and
subject to the prior satisfaction or waiver of the conditions of the Offer,
accept for payment Company Common Stock tendered as soon as it is legally
permitted to do so under applicable law; provided, however, that if, immediately
prior to the initial expiration date of the Offer (as it may be extended), the
Company Common Stock tendered and not withdrawn pursuant to the Offer equals
less than 90% of the outstanding Company Common Stock, Merger Sub may extend the
Offer two times for a period not to exceed ten business days, notwithstanding
that all conditions to the Offer are satisfied as of such expiration date of the
Offer.

          (b)  As soon as practicable on the date the Offer is commenced, Parent
and Merger Sub shall file with the United States Securities and Exchange
Commission (the "SEC") a Tender Offer Statement on Schedule 14D-1 with respect
to the Offer (together with all amendments and supplements thereto and including
the exhibits thereto, the "Schedule 14D-1").

                                       9
<PAGE>
 
The Schedule 14D-1 will include, as exhibits, the Offer to Purchase and a form
of letter of transmittal and summary advertisement (collectively, together with
any amendments and supplements thereto, the "Offer Documents"). The Offer
Documents will comply in all material respects with the provisions of applicable
federal securities laws and, on the date filed with the SEC and on the date
first published, sent or given to the Stockholders, shall not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading, except that no
representation is made by Parent or Merger Sub with respect to information
furnished by the Company to Parent or Merger Sub, in writing, expressly for
inclusion in the Offer Documents. The information supplied by the Company to
Parent or Merger Sub, in writing, expressly for inclusion in the Offer Documents
and by Parent or Merger Sub to the Company, in writing, expressly for inclusion
in the Schedule 14D-9 will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading.

          (c)  Each of Parent and Merger Sub will take all steps necessary to
cause the Offer Documents to be filed with the SEC and to be disseminated to the
Stockholders, in each case as and to the extent required by applicable federal
securities laws. Each of Parent and Merger Sub, on the one hand, and the
Company, on the other hand, will promptly correct any information provided by it
for use in the Offer Documents if and to the extent that it shall have become
false or misleading in any material respect and Parent and Merger Sub will take
all steps necessary to cause the Offer Documents as so corrected to be filed
with the SEC and to be disseminated to the Stockholders, in each case as and to
the extent required by applicable federal securities laws. The Company and its
counsel shall be given the opportunity to review the Schedule 14D-1 before it is
filed with the SEC. In addition, Parent and Merger Sub will provide the Company
and its counsel, in the form in which they are received, with any comments,
whether written or oral, Parent, Merger Sub or their counsel may receive from
time to time from the SEC or its staff with respect to the Offer Documents
promptly after the receipt of such comments.

     2.2  Company Actions.

          (a)  The Company hereby approves of and consents to the Offer and
represents that its Board of Directors, at a meeting duly called and held, has
(i) unanimously determined that each of the Agreement, the Offer and the Merger
are fair to and in the best interests of the Stockholders, (ii) approved this
Agreement and the transactions contemplated hereby, including the Offer and the
Merger (collectively, the "Transactions"), and (iii) resolved to recommend that
the Stockholders accept the Offer, tender their Company Common Stock thereunder
to Merger Sub and approve and adopt this Agreement and the Merger; provided,
that such recommendation may be withdrawn, modified or amended if, in the good
faith opinion of the Board of Directors, based upon the receipt of advice from
outside independent legal counsel and after consultation with a nationally

recommendation could violate the Board's fiduciary duties under applicable Law.

          (b)  Concurrently with the commencement of the Offer, the Company
shall file with the SEC a Solicitation/Recommendation Statement on Schedule 
14D-9 (together with all amendments and supplements thereto and including the
exhibits thereto, the "Schedule 14D-9") which shall contain the approval and
recommendation of the Board referred to in Section 2.2(a) hereof. The Schedule
14D-9 will comply in all material respects with the provisions of applicable
federal securities laws and, on the date filed with the SEC and on the date
first published, sent or given to the Stockholders, shall not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading, except that no
representation is made by the Company with respect to information furnished by
Parent or Merger Sub, in writing, expressly for inclusion in the Schedule 14D-9.
The Company further agrees to take all steps necessary to cause the Schedule 
14D-9 to be filed with the SEC and to be disseminated to the Stockholders, in
each case as and to the extent required by applicable federal securities laws.
Each of the Company, on the one hand, and Parent and Merger Sub, on the other
hand, agrees promptly to correct any information provided by it for use in the
Schedule 14D-9 if and to the extent that it shall have become false and
misleading in any material respect, and the Company further agrees to take all
steps necessary to cause the Schedule 14D-9 as so corrected to be filed with the
SEC and to be disseminated to the Stockholders, in each case as and to the
extent required by applicable federal securities laws. Parent and its counsel
shall be given the opportunity to review the Schedule 14D-9 before it is filed
with the SEC. In addition, the Company agrees to provide Parent, Merger Sub and
their counsel, in the form in which they are received, with any comments,
whether written or oral, that the Company or its counsel may receive from time
to time from the SEC or its staff with respect to the Schedule 14D-9 promptly
after the receipt of such comments or other communications.

          (c)  In connection with the Offer, the Company will promptly furnish
or cause to be furnished to Merger Sub mailing labels, security position
listings and any available listing, or computer file containing the names and
addresses of all recordholders of Company Common Stock as of a recent date, and
shall furnish Merger Sub with such additional information (including, but not
limited to, updated lists of Stockholders and their addresses, mailing labels
and lists of security positions) and assistance as Merger Sub or its agents may
reasonably request in communicating the Offer to the record and beneficial
holders of the Company Common Stock. Except for such steps as are necessary to
disseminate the Offer Documents, Parent and Merger Sub shall hold in confidence
the information contained in any of such labels and lists and the additional
information referred to in the preceding sentence, will use such information
only in connection with the Offer, and, if this Agreement is terminated, will,
upon request of the Company, deliver or cause to be delivered to the Company all
copies of such information then in its possession or the possession of its
agents or representatives.

      2.3 Directors.

          (a)  Promptly upon the purchase of and payment for any Company Common
Stock by Parent or any of its Subsidiaries which represents at least a majority
of the outstanding Company Common Stock (on a Fully Diluted Basis), Parent shall
be entitled to designate such number of directors, rounded up to the next whole
number, on the Board of Directors of the

                                      11
<PAGE>
 
Company as is equal to the product of the total number of directors on such
Board (giving effect to the directors designated by Parent pursuant to this
sentence) multiplied by the percentage that the number of shares of Company
Common Stock so accepted for payment bears to the total number of shares then
outstanding. In furtherance thereof, the Company shall, upon request of Merger
Sub, promptly either increase the size of its Board of Directors or secure the
resignation of such number of its incumbent directors, or both, as is necessary
to enable Parent's designees to be so elected to the Company's Board, and shall
take all actions available to the Company to cause Parent's designees to be so
elected. At such time, the Company shall, if requested by Parent, also cause
persons designated by Parent to constitute at least the same percentage (rounded
up to the next whole number) as is on the Company's Board of Directors on each
committee of the Company's Board of Directors. The Parent shall use its best
efforts to cause the Company to have at least one independent director until the
Effective Time, including, but not limited to retaining one of the Company's
current directors.

          (b)  The Company shall promptly take all actions required pursuant to
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder in order
to fulfill its obligations under Section 2.3(a), including mailing to
shareholders the information required by such Section 14(f) and Rule 14f-1 as is
necessary to enable Parent's designees to be elected to the Company's Board of
Directors. Parent or Merger Sub will supply the Company and be solely
responsible for any information provided by them in writing expressly for
inclusion in the information sent to Stockholders with respect to either of them
and their nominees, officers, directors and affiliates required by such Section
14(f) and Rule 14f-1. The provisions of this Section 2.3 are in addition to and
shall not limit any rights which the Merger Sub, Parent or any of their
affiliates may have as a holder or beneficial owner of Company Common Stock as a
matter of law with respect to the election of directors or otherwise.

      2.4 The Merger. Upon the terms and subject to the conditions set forth in
this Agreement and in accordance with the Delaware General Corporation Law
("DGCL") at the Effective Time, Merger Sub shall be merged with and into the
Company, the separate corporate existence of Merger Sub shall cease and the
Company shall (i) be the surviving corporation in the Merger (in such capacity,
the "Surviving Corporation"), (ii) succeed to and assume all the rights and
obligations of Merger Sub in accordance with the DGCL, and (iii) continue its
corporate existence under the laws of the State of Delaware. The Merger shall be
pursuant to the provisions of, and shall be with the effect provided in, the
DGCL. In accordance with the DGCL, all of the rights, privileges, property,
powers and franchises of the Company and Merger Sub shall vest in the Surviving
Corporation, and all of the debts, liabilities and duties of the Company and
Merger Sub shall become the debts, liabilities and duties of the Surviving
Corporation.

     2.5  Effective Time; Filing of Certificate of Merger. Subject to the terms
of this Agreement, the parties hereto shall cause the Merger to be consummated
by filing a properly executed Certificate of Merger or other appropriate
documents with the Secretary of State of the State of Delaware in accordance
with the provisions of the DGCL. The Merger shall become effective at the time
of such filing of the Certificate of Merger with the Secretary of State of the
State of Delaware or at such later date or time as Merger Sub and the Company
shall agree and specify in the Certificate of Merger (the "Effective Time").

                                      12
<PAGE>
 
     2.6  Certificate of Incorporation. At the Effective Time, the Certificate
of Incorporation of Merger Sub as in effect immediately prior to the Effective
Time shall be the Certificate of Incorporation of the Surviving Corporation
until thereafter amended in accordance with its terms and the DGCL.

     2.7  Bylaws. At the Effective Time, the Bylaws of Merger Sub as in effect
immediately prior to the Effective Time shall be the Bylaws of the Surviving
Corporation until thereafter amended in accordance with their terms and the
DGCL.

     2.8  Directors and Officers. At the Effective Time, the directors of Merger
Sub and the officers of the Company immediately prior to the Effective Time
shall be the initial directors and officers of the Surviving Corporation. Each
director and officer of the Surviving Corporation shall hold office in
accordance with the Certificate of Incorporation and Bylaws of the Surviving
Corporation until his or her death, resignation or removal or a successor is
duly elected or appointed and qualified.

     2.9  Additional Actions. If, at any time after the Effective Time, the
Surviving Corporation shall consider or be advised that consistent with the
terms of this Agreement any further assignments or assurances in law or any
other acts are necessary or desirable (i) to vest, perfect or confirm, of record
or otherwise, in the Surviving Corporation, title to and possession of any
property or right of either Constituent Corporation acquired or to be acquired
by reason of, or as a result of, the Merger, or (ii) otherwise to carry out the
purposes of this Agreement, then, subject to the terms and conditions of this
Agreement, each such Constituent Corporation and its officers and directors
shall be deemed to have granted to the Surviving Corporation an irrevocable
power of attorney to execute and deliver all such deeds, assignments and
assurances in law and to do all acts necessary or proper to vest, perfect or
confirm title to and possession of such property or rights in the Surviving
Corporation and otherwise to carry out the purposes of this Agreement; and the
officers and directors of the Surviving Corporation are fully authorized in the
name of either Constituent Corporation to take any and all such action.

     2.10 Time and Place of Closing. The closing of the Merger (the "Closing")
shall take place (i) at the offices of Sullivan & Cromwell, 375 Park Avenue, New
York, New York on a date and at a time to be specified by the parties, which

of all of the conditions set forth in Article 7, or (ii) at such other place, at
such other time or on such other date as the parties may mutually agree (the
date of the Closing is hereinafter sometimes referred to as the "Closing Date").

     2.11  Conversion of Company Common Stock.

          (a)  Each share of the Company Common Stock issued and outstanding
immediately prior to the Effective Time (except for Dissenting Shares, shares of
Company Common Stock beneficially owned by Parent and Merger Sub, and shares of
Common Stock held in the Company's treasury), shall, by virtue of the Merger and
without any action on the part of the Company, the Parent, Merger Sub or the
holder thereof, be converted into the right to receive

                                      13
<PAGE>
 
the Offer Price in cash, payable to the holder thereof, without any interest
thereon ("Merger Consideration"), as soon as reasonably practicable after the
surrender of the certificate(s) representing such Company Common Stock as
provided in Section 2.12.

          (b)  Each share of common stock, par value $0.01 per share, of Merger
Sub issued and outstanding immediately prior to the Effective Time shall, by
virtue of the Merger and without any action on the part of the holder thereof,
be converted into one share of common stock of the Surviving Corporation. Each
certificate evidencing ownership of any such shares shall, following the Merger,
evidence ownership of the same number of shares of common stock of the Surviving
Corporation.

          (c)  Payments in respect of the Existing Options are provided for in
Section 2.18 below.

     2.12  Exchange of Shares.

          (a)  Prior to the Effective Time, the Company shall appoint a Person
that is reasonably acceptable to the Parent to act as the exchange agent
hereunder (the "Exchange Agent") to receive in trust the funds to which
Stockholders shall become entitled upon surrender of the certificates for
exchange in accordance with this Section 2.12.

     As soon as reasonably practicable after the Effective Time, the Exchange
Agent shall mail to each holder of record of a share certificate which
immediately prior to the Effective Time represented outstanding Company Common
Stock (other than Parent, the Company, any Subsidiary of Parent and any holder
of Dissenting Shares): (1) a letter of transmittal (a "Letter of Transmittal")
which shall (x) specify that delivery shall be effected, and risk of loss and
title to each such certificate shall pass, only upon delivery of such
certificates to the Exchange Agent, (y) contain a representation in a form
reasonably satisfactory to the Parent as to the good and marketable title to the
Company Common Stock held by such holder free and clear of any Lien, and (z)
contain such other provisions as the Company and the Parent may reasonably
specify; and (2) instructions to effect the surrender of such certificate(s) in
exchange for a check in an amount equal to the Offer Price multiplied by the
number of shares of Company Common Stock represented by such certificate(s).

     Parent shall cause Merger Sub to provide the Exchange Agent from time to
time on behalf of the Stockholders, amounts in cash required to make prompt
payment of the Merger Consideration provided for in Section 2.11(a) to the
holder of such certificate(s). Parent shall provide to the Company prompt
written notice of the provision of funds to the Exchange Agent.

     Thereafter (except as otherwise provided for in Section 2.12(c)), each
holder of certificate(s) representing Company Common Stock may surrender such
certificate(s) to the Exchange Agent and (subject to applicable abandoned
property, escheat and similar laws) receive from the Exchange Agent in exchange
therefor an amount equal to the product of (x) the Offer Price and (y) the
number of shares of Company Common Stock represented by the certificate(s)

                                      14
<PAGE>
 
so surrendered, without interest, but such holder shall have no rights
whatsoever against the Surviving Corporation.

     Upon the surrender of any such certificate(s) to the Exchange Agent, the
Exchange Agent shall promptly surrender such certificate(s) to the Surviving
Corporation for cancellation.

          (b)  If the consideration payable for any Company Common Stock is to
be delivered to a person other than the person in whose name the certificate(s)
representing such Company Common Stock is registered, it shall be a condition of
such delivery that the certificate(s) so surrendered shall be properly endorsed
or accompanied by appropriate stock powers, in either case signed exactly as the
name of the record holder appears on such certificate, and shall otherwise be in
proper form for transfer, and that the person requesting such delivery shall pay
to the Exchange Agent or the Surviving Corporation, as the case may be, any
transfer or other taxes required by law as a result of such delivery to a person
other than the record holder of the certificate(s) surrendered or shall
establish to the Exchange Agent's and the Surviving Corporation's reasonable
satisfaction that such tax has been paid or is not payable.

          (c)  From and after one (1) year following the Closing Date, any
Stockholders who have not theretofore complied with Section 2.12(a) shall
thereafter look only to the Surviving Corporation for delivery of the Merger
Consideration, subject in all events to all applicable escheat and other similar
laws.

          (d)  Until surrender as contemplated by this Section 2.12,
certificate(s) representing Company Common Stock shall be deemed at all times
after the Effective Time to represent only the right to receive upon surrender
the Merger Consideration as specified in this Agreement.

          (e)  No interest shall accrue or be payable with respect to any
amounts which any Stockholder or Optionholder shall be entitled to receive
pursuant to this Agreement. The Exchange Agent shall be authorized to pay the
Merger Consideration attributable to any certificate(s) representing Company
Common Stock which has been lost or destroyed upon receipt of evidence of
ownership of the Company Common Stock represented thereby and of appropriate
indemnification and/or bond in each case reasonably satisfactory to the Company
or the Surviving Corporation, as the case may be (but no bond shall be required
in cases of 25 shares or less).

          (f)  Neither the Exchange Agent nor any party to this Agreement shall
be liable to any Stockholder or Optionholder for any Company Common Stock, any
Existing Options, the Offer Price, the Merger Consideration, or cash delivered
to a public official pursuant to any abandoned property, escheat or similar law.

          (g)  The Exchange Agent shall be entitled to deduct and withhold from
the consideration otherwise payable pursuant to this Agreement to any
Stockholder or Optionholder such amounts as the Company reasonably determines
are required to be deducted and withheld with respect to the making of such
payment under the Code, or any provision of state, local or foreign tax Law. To
the extent that amounts are so withheld by the Exchange Agent, such

                                      15
<PAGE>
 
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the Stockholder or Optionholder in respect of which such deduction
and withholding was made by the Exchange Agent.

     2.13  No Further Rights or Transfers; Cancellation of Treasury Shares.
Except for the surrender of the certificate(s) representing the Company Common
Stock in exchange for the Merger Consideration with respect to each share of
Company Common Stock or the perfection of appraisal rights with respect to the
Dissenting Shares, at and after the Effective Time, the holder of shares of
Company Common Stock shall cease to have any rights as a stockholder of the
Company, and no transfer of shares of Company Common Stock shall thereafter be
made on the stock transfer books of the Surviving Corporation. Each share of
Company Common Stock held in the Company's treasury or held by Parent or Merger
Sub immediately prior to the Effective Time shall, by virtue of the Merger, be
canceled and retired and cease to exist without any conversion thereof.

     2.14  Dissenters' Rights. Shares of Company Common Stock which immediately
prior to the Effective Time are held by Stockholders who have properly exercised
and perfected appraisal rights under Section 262 of the DGCL (the "Dissenting
Shares") shall, if required by the DGCL, but only to the extent required
thereby, not be converted into the right to receive the Merger Consideration,
but the holders of Dissenting Shares shall be entitled to receive such
consideration as shall be determined pursuant to Section 262 of the DGCL;
provided, however, that if any such holder shall have failed to perfect or shall
withdraw or lose his right to appraisal and payment under the DGCL, such
holder's shares of Company Common Stock shall thereupon be deemed to have been
converted as of the Effective Time into the right to receive the Merger
Consideration, without any interest thereon, and such shares shall no longer be
Dissenting Shares. The Company shall give the Parent, Merger Sub and the
Exchange Agent prompt notice of any claim by a Stockholder for payment of fair
value for Dissenting Shares as provided in Section 262 of the DGCL. Prior to the
Effective Time, the Company will not, except with the prior written consent of
Parent and Merger Sub, make any payments with respect to, or settle or offer to
settle, any such demands.

      2.15 Special Meeting of Stockholders.

          (a)  If required by applicable law in order to consummate the Merger,
the Company agrees to take all steps necessary to cause a special meeting of the
Stockholders (the "Special Meeting") to be duly called, noticed, convened and
held as soon as practicable following the acceptance for payment and purchase of
shares of Company Common Stock by the Parent or its affiliates pursuant to the
Offer for the purpose of voting to approve this Agreement and the Merger. In
connection with the Special Meeting, the Board of Directors of the Company
shall, subject to the Board's fulfillment of its fiduciary duties under
applicable Law, unanimously recommend to the Stockholders that the Stockholders
vote in favor of the approval of this Agreement and the Merger.

          (b)  In connection with the Special Meeting, the Company agrees to
promptly prepare and cause to be filed with the SEC and mailed to the
Stockholders a notice of the Special

                                      16
<PAGE>
 
Meeting and a definitive proxy statement (the "Proxy Statement") and shall cause
such notice to be mailed no later than the time required by applicable Law and
the certificate of incorporation and bylaws of the Company. The Parent and
Merger Sub agree to provide the Company with any information for inclusion in
the Proxy Statement (or any amendments or supplements thereto) which is required
by applicable Law or which is reasonably requested by the Company. The Company
shall consult with the Parent and Merger Sub with respect to the Proxy Statement
(and any amendments or supplements thereto) and shall afford the Parent and
Merger Sub reasonable opportunity to comment thereon prior to its finalization.
If, at any time prior to the Special Meeting, any event shall occur relating to
the Company or the transactions contemplated by this Agreement which should be
set forth in an amendment or a supplement to the Proxy Statement, the Company
will promptly notify in writing the Parent and Merger Sub of such event. In such
case, the Company, with the cooperation of the Parent and Merger Sub, will
promptly prepare and mail such amendment or supplement and the Company shall
consult with the Parent and Merger Sub with respect to such amendment or
supplement and shall afford the Parent and Merger Sub reasonable opportunity to
comment thereon prior to such mailing. The Company agrees to notify the Parent
and Merger Sub at least three (3) days prior to the mailing of the Proxy
Statement (or any amendment or supplement thereto) to the Stockholders.

          (c)  The Parent agrees that if any event with respect to the Parent,
Merger Sub or their officers or directors shall occur which is required to be
described in an amendment or supplement to the Proxy Statement or any other
filing with the SEC that may be required in connection with this Agreement, the
Merger and all matters related thereto, the Parent will promptly inform the
Company thereof and the Company will cause such event to be so described and
such amendment or supplement to be promptly filed with the SEC and, as required
by law, disseminated to the Stockholders; provided, however, that prior to such
filing or mailing the Company shall consult with the Parent and Merger Sub with
respect to such amendment, supplement or other filing and shall afford the
Parent and Merger Sub a reasonable opportunity to comment thereon.

     2.16 Merger Without Meeting of Stockholders. Notwithstanding Section 2.15
hereof, in the event that Parent, Merger Sub and any other Subsidiaries of
Parent shall acquire in the aggregate at least 90% of the Company Common Stock,
pursuant to the Offer or otherwise, the parties hereto shall, at the request of
Parent and subject to Article 7 hereof, take all necessary and appropriate
action to cause the Merger to become effective as soon as practicable after such
acquisition, without a meeting of stockholders of the Company, in accordance
with Section 253 of the DGCL.

     2.17 Reasonable Best Efforts. So long as this Agreement has not been
terminated, the Company, Parent and Merger Sub shall: (i) promptly make their
respective filings and thereafter make any other submissions required under all
applicable laws with respect to this Agreement, the Offer, the Merger and the
other transactions contemplated hereby and (ii) use their respective reasonable
best efforts to promptly take, or cause to be taken, all other actions and do,
or cause to be done, all other things necessary, proper or appropriate to
consummate and make effective the Offer and the Merger as provided for in this
Agreement.

     2.18 Existing Options.

          (a)  As of the Effective Time, each Existing Option other than the
Company Preferred Shares which is outstanding at the Effective Time will be
exchanged for, and the holders of each such Existing Option will be entitled to
receive at the Closing (or thereafter, if necessary) upon surrender of such
Existing Option for cancellation, cash equal to (i) the product of (a) the
positive difference, if any, between the Offer Price less the exercise price of
each such Existing Option, multiplied by (b) the number of shares of Company
Common Stock covered by such Existing Option. Notwithstanding the foregoing,
from and after the Effective Time each holder of Company Preferred Shares shall
have the right to convert its Company Preferred Shares only into the amount of
cash provided for by the terms of the Company Preferred Shares after giving
effect to any adjustment in the conversion price provided for by such terms,
which the Company hereby acknowledges and represents shall be $26.40 per Company
Preferred Share.

          (b)  The Company shall take all actions reasonably necessary to ensure
that from and after the Effective Time the Surviving Corporation will not be
bound by any options, warrants, rights or agreements which would entitle any
person, other than Parent or Merger Sub, to beneficially own shares of Surviving
Corporation or Parent or receive any payments (other than as set forth in
Section 2.18(a)) in respect of such options, warrants, rights or agreements. The
Company shall take all actions necessary to terminate each plan with respect to
Existing Options as of the Effective Time.


                                   ARTICLE 3

                                OTHER AGREEMENTS

     3.1  Access. Subject to the provisions of the Confidentiality Agreement
referred to in Section 3.6 below, and so long as this Agreement has not been
terminated as herein provided, upon reasonable request, the Company shall grant
to Parent, Merger Sub and their agents, accountants, attorneys and other
advisers reasonable access during normal business hours to the properties,
facilities, books, records, financial statements and other documents and
materials of the Company and its Subsidiaries. In addition, the Company shall
confer and consult with representatives of Parent, as Parent may reasonably
request, to report on operational matters, financial matters and the status of
ongoing business operations of the Company.

     3.2  Company Disclosure Letter. The Company has delivered to Parent the
Company Disclosure Letter as provided in Article 4. The Company Disclosure
Letter shall be signed by the President and the Secretary of the Company and
shall state that such Company Disclosure Letter was delivered pursuant to this
Agreement and that such Company Disclosure Letter is the Company Disclosure
Letter referred to in this Agreement. The Company Disclosure Letter is deemed to
constitute an integral part of this Agreement and to modify, as specified, the
representations, warranties, covenants or agreements of the Company contained in
this Agreement.

                                      18
<PAGE>
 
     3.3  Deliveries of Information. From time to time after the date of this
Agreement and prior to the Closing Date (unless this Agreement is terminated),
the Company shall furnish promptly to Parent a copy of each report, schedule and
other document filed by the Company or received by the Company after the date of
this Agreement pursuant to the requirements of federal or state securities Laws
promptly after such documents are available.

     3.4  Acquisition Proposals.

          (a)  The Company agrees that, as of the date hereof, it, its
Affiliates, and the respective directors, officers, employees, agents and
representatives of the foregoing, shall immediately cease and cause to be
terminated any existing activities, discussions or negotiations with any Person
(other than Parent and its representatives) conducted heretofore with respect to
any Acquisition Transaction. Prior to the Effective Time, the Company agrees
that neither it, any of its Affiliates, nor any of the respective directors,
officers, employees, agents or representatives of the foregoing, will, directly
or indirectly, (i) solicit or initiate, or knowingly facilitate or encourage
(including by way of furnishing or disclosing non-public information) any
Acquisition Transaction or (ii) negotiate, explore or otherwise engage in
discussions with any Person (other than Parent and its representatives) with
respect to any Acquisition Transaction, or which may lead to a proposal for an
Acquisition Transaction, or enter into any agreement, arrangement or
understanding with respect to any such Acquisition Transaction or which would
require it to abandon, terminate or fail to consummate the Merger or any other
transaction contemplated by this Agreement, or which may cause the Board to
withdraw, modify or amend its recommendation that the Stockholders accept the
Offer, tender their Company Common Stock to Merger Sub or approve and adopt the
Agreement and the Merger; provided, however, that the Company may, in response
to a bona fide unsolicited proposal from a third party regarding an Acquisition
Transaction, (x) furnish information to and engage in discussions and
negotiations with such third party (subject to such third party entering into a
confidentiality agreement with the Company containing terms substantially
similar to the Confidentiality Agreement (as defined herein)), but only if the
Board of Directors of the Company reasonably determines in good faith, after
consultation with its outside independent counsel and a nationally recognized
investment bank, that such unsolicited proposal could reasonably lead to a
Superior Proposal and that failing to take such action could violate the Board's
fiduciary duties under applicable Law and (y) take and disclose to the
Stockholders any proposal, and make related filings with the SEC, as required by
Rule 14e-3 and 14d-9 under the Exchange Act. Any violation of this Section 3.4
by any director, officer, Affiliate, investment banker, financial advisor,
attorney or other advisor or representative of the Company, whether or not such
Person is purporting to act on behalf of the Company, or otherwise, shall be
deemed to be a breach of this Section 3.4 by the Company. As used herein,
"Acquisition Transaction" means any inquiries or the making of any proposal
other than by Parent or any of its Affiliates with respect to any merger,
consolidation or other business combination involving the Company or any
Subsidiary or with respect to the acquisition of beneficial ownership of all or
any significant part of the assets or capital stock of the Company (including
assets held by, or shares of, Subsidiaries). As used herein, "Superior Proposal"
means a bona fide, written Acquisition Proposal for at least a majority of the
outstanding Company Common Stock that is on terms that the Board reasonably
determines in good faith, after consultation with its outside independent legal
counsel and a nationally recognized investment bank, would result

                                      19
<PAGE>
 
in a transaction, if consummated, that is more favorable to the Stockholders
from a financial point of view than the Offer and the Merger.

          (b)  The Company agrees to advise Parent promptly (within 24 hours in
the case of written inquiries or proposals, and otherwise within 48 hours) of
(x) the existence of any inquiries or proposals (or desire to make a proposal)
received by (or indicated to) it after the date hereof, any such information
requested from, or any negotiations or discussions sought to be initiated or
continued with, the Company, its Affiliates, or any of the respective directors,
officers, employees, agents or representatives of the foregoing, in each case
from a Person (other than Parent and its representatives) with respect to an
Acquisition Transaction, and (y) the material terms thereof (including the
identity of such Person). If the Company engages in discussions or negotiations
with respect to any such Acquisition Proposal thereafter in accordance with
clause (x) above, the Company shall keep Parent and Merger Sub informed on a
timely basis as to such discussions and negotiations and the material terms
being discussed or negotiated.

     3.5  Public Announcements. Any public announcement made by or on behalf of
either Parent or the Company prior to the termination of this Agreement pursuant
to Article 8 hereof concerning this Agreement, the transactions described herein
or any other aspect of the dealings heretofore had or hereafter to be had
between the Company and Parent and their respective Affiliates must first be

<PAGE>

Subsidiary or, to the knowledge of the Company, any of the Joint Ventures
relating to any of the foregoing.

     4.9  Performance of Contracts. Each of the material Contracts of the
Company and its Subsidiaries is in full force and effect and constitutes the
legal and binding obligation of the Company or its Subsidiaries and, to the
knowledge of the Company, constitutes the legal and binding obligation of the
other parties thereto. Except as disclosed in Section 4.9 of the Company
Disclosure Letter, there are no existing breaches or defaults by the Company or
its Subsidiaries under any such Contract the effect of which could constitute a
Material Adverse Effect on the Company, and, to the knowledge of the Company, no
event has occurred or state of circumstances or facts exists which, with the
passage of time or the giving of notice or both, could reasonably be expected to
constitute such a breach or default.

     4.10  Insurance. Section 4.10 of the Company Disclosure Letter lists all of
the Existing Insurance Policies of the Company and its Subsidiaries and all
outstanding claims against such Existing Insurance Policies. Neither the Company
nor any of its Subsidiaries has received notice of cancellation or termination

Policy. All such Existing Insurance Policies provide adequate insurance coverage
for the assets and properties of the Company and its Subsidiaries necessary for
the conduct of its business as currently being conducted.

     4.11 Employee Benefit Plans. Except as disclosed in Section 4.11 of the
Company Disclosure Letter for the six-calendar year period prior to and
including the calendar year in which the Closing Date occurs:

          (a)  Employee Benefit Plans. Neither the Company nor any ERISA
Affiliate maintains or contributes to, any Employee Benefit Plan. Each Employee
Benefit Plan that is subject to ERISA or the Code is in substantial compliance
with ERISA and the Code. True and complete copies of all Employee Benefit Plans,
including, but not limited to, any trust instruments

                                      26
<PAGE>
 
and insurance contracts forming a part of any Employee Benefit Plans, and all
amendments thereto have been provided or made available to Parent. Each Pension
Plan which is intended to meet the requirements of Section 401(a) of the Code
has been determined by the Internal Revenue Service to be "qualified" within the
meaning of the Code with respect to "TRA" (as defined in Section 1 of Rev. Proc.
93-39) or will be filed with the Internal Revenue Service with a request for a
determination letter on or prior to the end of the applicable remedial amendment
period and, to the knowledge of the Company, there are no facts which would
adversely affect the tax qualified status of any Pension Plan.

          (b)  ERISA; Code. There is no accumulated funding deficiency, within
the meaning of Section 302 of ERISA or Section 412 of the Code, in connection
with a Pension Plan. No reportable event, as defined in ERISA (other than
reportable events for which the 30-day notice requirement has been waived), has
occurred in connection with a Pension Plan. Neither the Company nor any ERISA
Affiliate is contributing to, nor has any such party incurred any liability
with respect to, any multi-employer plan, as defined in Section 3(37) of ERISA.

          (c)  Compliance. Neither the Company nor any ERISA Affiliate has
incurred, directly or indirectly, any liability to or on account of a Pension
Plan or any terminated or frozen single employer Pension Plan within the meaning
of Section 4001(a)(15) of ERISA; no proceedings have been instituted to
terminate any Pension Plan; and, to the knowledge of the Company, no condition
exists that presents a material risk to the Company or any ERISA Affiliate of
incurring a liability to or on account of a Pension Plan.

          (d)  Funding. As of December 31, 1999, the current value of the assets
of each Pension Plan exceeds the accumulated benefit obligation for the Pension
Plan as defined under FASB No. 87 (as amended by statement 132); and all
contributions or other amounts payable by the Company as of the Effective Time
with respect to each of its Employee Benefit Plans in respect of current or
prior plan years have been either paid or accrued on the balance sheet of the
Company. There are no pending or, to the knowledge of the Company, threatened or
anticipated claims (other than routine claims for benefits) by, on behalf of or
against any of the Employee Benefit Plans or any trusts related thereto and
neither the Company nor any Subsidiary has provided, or is required to provide,
security to any Pension Plan or to any single-employer plan of an ERISA
Affiliate pursuant to Section 401(a)(29) of the Code.

          (e)  Other Plan Obligations. To the knowledge of the Company, neither
the Company nor any ERISA Affiliate, nor any of its Employee Benefit Plans, nor
any trust created thereunder, nor any trustee or administrator thereof has
engaged in a transaction in connection with which the Company or any ERISA
Affiliate, any of its Employee Benefit Plans, any such trust, or any trustee or
administrator thereof, or any party dealing with any of its Employee Benefit
Plans or any such trust could be subject to either a civil penalty assessed
pursuant to Section 409 or 502(i) of ERISA or a tax imposed pursuant to Section
4975 or 4976 of the Code. No Employee Benefit Plan of the Company provides death
or medical benefits (whether or not insured), with respect to current or former
employees of the Company or any ERISA Affiliate beyond their retirement or other
termination of service other than (i) coverage mandated by applicable Law or
(ii) death benefits under any "employee pension plan," as that term is defined
in Section 3(2) of ERISA.

                                      27
<PAGE>
 
Subject to requirements in a collective bargaining agreement, under the terms of
the Employee Benefit Plans, the Company or any Subsidiary may amend or terminate
any such Employee Benefit Plan at any time without incurring any liability
thereunder. The consummation of the transactions contemplated by this Agreement
will not (i) entitle any employees of the Company or any Subsidiary to severance
pay; (ii) accelerate the time of payment or vesting or trigger any payment or
funding (through a grantor trust or otherwise) of compensation or benefits
under, increase the amount payable or trigger any other material obligation
pursuant to, any of the Employee Benefit Plans; or (iii) result in any breach or
violation of, or a default under, any of the Employee Benefit Plans. All
Employee Benefit Plans covering current or former non-U.S. employees comply in
all material respects with applicable local law. The Company and its
Subsidiaries have no material unfunded liabilities with respect to any Pension
Plan that covers such non-U.S. employees.

     4.12  Brokers' and Finders' Fees. Except for fees to be paid to Salomon
Smith Barney Inc., the Company has not incurred any brokers', finders',
investment bankers' or any similar fee in connection with the transactions
contemplated by this Agreement. A true, correct and complete copy of the
engagement letter between the Company and Salomon Smith Barney Inc. has been
made available to Parent.

     4.13 Taxes.

          (a)  Tax Returns. For all years for which the applicable statutory
period of limitations has not expired, the Company and each of its Subsidiaries
has timely and properly filed, and will through the Closing Date timely and
properly file, all material federal, state, local and foreign tax returns
(including but not limited to income, franchise, sales, payroll, employee
withholding and social security and unemployment) which were or will be required
to be filed and all such tax returns are or will be true and complete in all
material respects. The Company and each of its Subsidiaries has paid all taxes
shown on such returns (including interest and penalties) and withholding amounts
owed by the Company and each of its Subsidiaries except where the failure to do
so would not cause a Material Adverse Effect on the Company. The Company and
each of its Subsidiaries have made adequate provisions or reserves for any
accrued taxes that are not yet due and payable. No material tax deficiencies
have been proposed or assessed against the Company or its Subsidiaries. To the
knowledge of the Company, no issue has been raised in any prior tax audit of the
Company or its Subsidiaries which, by application of the same or similar
principles, could reasonably be expected, upon a future tax audit of the Company
or its Subsidiaries to result in a proposed deficiency for any period and which
deficiency would have a Material Adverse Effect on the Company. Except as
disclosed in Section 4.13 of the Company Disclosure Letter, the Company is not
liable for any taxes attributable to any other Person, whether by reason of
being a member of another affiliated group, being a party to a tax sharing
agreement, as a transferee or successor, or otherwise.

          (b)  Audits. Except as disclosed on Section 4.13 of the Company
Disclosure Letter, the Company and each of its Subsidiaries have not consented
to any extension of the statute of limitations with respect to any open federal,
state or local tax returns.

                                      28
<PAGE>
 
          (c) Liens. There are no tax Liens upon any property or assets of the
Company necessary for the conduct of its business as currently being conducted,
except for Liens for current taxes not yet due and payable, and except for such
claims which, individually or in the aggregate, would not have a Material
Adverse Effect on the Company.

          (d) Deliveries. The Parent has had the opportunity to review correct
and complete copies of all tax returns and reports of the Company filed for all
periods not barred by the applicable statute of limitations through the date
hereof. Except as disclosed in Section 4.13 of the Company Disclosure Letter, no
examination or audit of any tax return or report for any period not barred by
the applicable statute of limitations has occurred, no such examination is in
progress and, the Company has not received written notice that any such
examination or audit is planned.

          (e) Withholding Taxes. The Company has properly withheld and timely
paid substantially all withholding and employment taxes which it was required to
withhold and pay relating to salaries, compensation and other amounts heretofore
paid to its employees or other Persons. All Forms W-2 and 1099 required to be
filed with respect thereto have been timely and properly filed except where the
failure to file would not have a Material Adverse Effect.

          (f) Other Representations. The Company has not and will not make any
elections under Section 341(f) of the Code and, except as shown in Section 4.13
of the Company Disclosure Letter, has and will not be subject to Section 280G of
the Code.

     4.14 Real Estate. Except as set forth in Section 4.14 of the Company
Disclosure Letter, the Real Estate: (a) constitutes all real property and
improvements leased or owned by the Company or any Subsidiary; and (b) is not
subject to any leases, tenancies, encumbrances or encroachments of any kind
except for Permitted Liens.

     4.15 Governmental Approvals. No permission, approval, determination,
consent or waiver by, or any declaration, filing or registration with, any
federal, state, local or foreign court, arbitral tribunal, administrative agency
or commission or other governmental or regulatory authority or administrative
agency (a "Governmental Entity") is required by the Company in connection with
the execution and delivery of this Agreement by the Company or the consummation
of the Offer or the consummation by the Company of the Merger or the other
transactions described herein, except for: (a) the approvals or filings in
connection with (i) the HSR Act as described in Section 7.1(a) and (ii) the
Exchange Act, including, without limitation, filing the Proxy Statement with the
SEC; (b) the filing of the Certificate of Merger as described in this Agreement;
and (c) such other permissions, approvals, determinations, consents, waivers,
declarations, filings, or registrations that are not material and that would not
materially impair the Company's ability to consummate the Merger and the other
transactions contemplated hereby.

     4.16 No Pending Acquisitions. Except for this Agreement and previously
executed confidentiality agreements, the Company is not a party to or bound by

licenses, permits, approvals, exemptions, orders, franchises, qualifications,
permissions, agreements and governmental authorizations required by Law and
required for the conduct of the business of the Company and its Subsidiaries and
the Joint Ventures as currently conducted, except where the failure to have the
same would not have a Material Adverse Effect on the Company and its
Subsidiaries, taken as a whole. No action or proceeding is pending or, to the
knowledge of the Company, threatened that is reasonably likely to result in a
revocation, non-renewal, termination, suspension or other material impairment of
any material Existing Permits of the Company or its Subsidiaries or the Joint
Ventures. The business of the Company and its Subsidiaries and to the Company's

<PAGE>
 
and except for such violations of any Environmental Law set forth on Section

terms and conditions of sale or lease. Except as set forth in Section 4.19 of
the Company Disclosure Letter, there are no existing or, to the knowledge of the
Company, threatened claims or any facts upon which a claim could be based,
against the Company, any of its Subsidiaries or any of the Joint Ventures for

product warranties which would, individually or in the aggregate, have a
Material Adverse Effect on the Company.

Person contesting or challenging the right of the Company or its Subsidiaries or

to the Company's knowledge, the consummation of the Merger and the other
transactions contemplated by this Agreement will not impair the validity,
enforceability, ownership or right of the Company or its Subsidiaries or, to the
knowledge of the Company, any of the Joint Ventures to use the Intangible Assets
currently used by it in the operation of its business except, in each case,
where the impairment would not have a Material Adverse Effect on the Company.

     4.21 Customers and Suppliers. Since December 31, 1998, there has been no
termination, cancellation or curtailment of the business relationship of the
Company with any customer or supplier or group of affiliated customers or

<PAGE>
 
Adverse Effect, and the Company has not received written notice of any such
termination, cancellation or curtailment.

copies of, all forms, reports, schedules, statements and other documents
required to be filed by it since December 31, 1996 under the Exchange Act or the
Securities Act (as such documents have been amended since the time of their

with the Merger, not contain any untrue statement of a material fact or omit to

     4.26 Opinion of Financial Advisor. The Board of Directors of the Company
has received the opinion of Salomon Smith Barney Inc., its financial advisor, to
the effect that, as of the date of this Agreement, the cash consideration to be
received in the Offer and the Merger by the Stockholders (other than Parent and
its Affiliates), based upon and subject to the assumptions and limitations set
forth in such opinion, is fair to such Stockholders from a financial point of
view.

     4.27 Certain Agreements. Except as set forth in Section 4.27 of the Company
Disclosure Letter, neither the Company nor any of its Subsidiaries is a party to
any oral or written agreement or plan, including any stock option plan, stock
appreciation rights plan, restricted stock plan or stock purchase plan, any of
the benefits of which will be increased, or the vesting of the benefits of which
will be accelerated, by the consummation of the Merger or any of the other
transactions contemplated by this Agreement. Except as described in Section 4.27
of the Company Disclosure Letter, the Merger and the other transactions
contemplated by this Agreement will not constitute a "change of control" under,
require the consent from or the giving of notice to any third party pursuant to,
or accelerate the vesting or repurchase rights under, any Contract to which the
Company or any of its Subsidiaries is a party, other than Contracts which are
not Contracts with directors, officers or employees of the Company or any
Subsidiary and which have been entered into in the ordinary course and are not
material. Except as set forth in Section 4.27 of the Company Disclosure Letter,
there are no amounts payable by the Company to any officers of the Company (in
their capacity as officers) as a result of the Merger or the other transactions
contemplated by this Agreement.

          (a) The Company has taken all action required to be taken by it in
order to exempt this Agreement and the Merger and the other transactions
contemplated hereby from, and this Agreement is exempt from, the requirements of
all anti-takeover Laws and regulations (collectively, "Takeover Laws") that
apply or may purport to apply to the Offer and the Merger, including, without
limitation, Section 203 of DGCL.

          (b) The Company has (i) duly entered into an appropriate amendment to
the Company Rights Agreement and (ii) taken all other action necessary or
appropriate so that the entering into of this Agreement and the consummation of
the Merger and the other transactions contemplated hereby do not and will not
result in the ability of any Person to exercise any Company Preferred Rights
under the Company Rights Agreement or enable or require the Company Preferred
Rights to separate from the shares of Company Common Stock to which they are
attached or to be triggered or become exercisable, and the Company Rights
Agreement, as so amended, has not been further amended or modified. In
particular, the Company has taken all actions necessary under the Rights
Agreement, so that the execution of this Agreement and any amendments thereto by
the parties hereto and the consummation of any of the transactions contemplated
hereby shall not cause (i) Parent and/or Merger Sub or their respective
Affiliates to become an Acquiring Person (as such terms are defined in the
Rights Agreement) unless this Agreement has been terminated in accordance with
its terms or (ii) a Distribution Date, a Shares Acquisition Date, or a
Triggering Event (as such terms are defined in the Rights Agreement) to

                                      33

occur, irrespective of the number of shares of Company Common Stock acquired
pursuant to the Offer, Merger or other transactions contemplated by this
Agreement.

     4.29 Year 2000 Compliance. Except as set forth on Schedule 4.29 of the
Company Disclosure Letter or as would not result in a Material Adverse Effect,
(i) all functions including, without limitation, date-reliant (which includes
year-reliant) functions of the information and business systems of the Company
and its Subsidiaries (collectively, the "Systems") are capable of continuing to
operate up to, during and after the year 2000, (ii) neither the performance nor
functionality of the Systems will be affected by any changes to the field
configuration which contains the date information within any part of the System
caused by the advent of the year 2000, and (iii) the Systems will perform
consistent with past performance and there shall be no faults in the processing
of dates and date-dependent information or data including, without limitation,
in calculations, comparisons and sequencing of information or data. Schedule
4.29 of the Company Disclosure Letter sets forth, with respect to any exception,
the nature of such exception in detail, including the nature of the problem, the
nature of the steps undertaken and planned, and the Company's good faith
estimate of the cost to correct such problem and its projection of a date for
project completion.

     4.30 Approval by Disinterested Directors. A majority of the Company's
Disinterested Directors (as defined in the Company's Restated Certificate of
Incorporation, as amended) have approved the Merger.

     6.2 Indemnification.

          (a) From and after the date of this Agreement through and including

neither Parent nor the Company will take any action, nor permit any action to be
taken, which would change or amend the provisions of the Certificate of
Incorporation or the Bylaws of the Company in effect on the date hereof relating
to limitation of liability or indemnification inconsistent with its obligations
under Section 6.2(b) hereof or eliminate or make any modification in the
Company's existing director's and officer's insurance inconsistent with its
obligations under Section 6.2(c) hereof. The Parent agrees that from and after
the Effective Time all rights to indemnification now existing in favor of
individuals who at or prior to the Effective Time were directors or officers of
the Company or any of its Subsidiaries as set forth in the Certificate of
Incorporation or the Bylaws of the Company shall survive the Merger with respect
to matters existing or occurring at or prior to the Effective Time and shall
continue in full force and effect for a period of six years following the
Effective Time.

          (b) The Company shall, and from and after the Effective Time, the
Surviving Corporation shall, indemnify, defend and hold harmless each person who
is now, or has been at any time prior to the date hereof or who becomes prior to
the Effective Time, an officer or director of the Company or any of its
Subsidiaries (each individually an "Indemnified Party" and, collectively, the
"Indemnified Parties") against all losses, claims, damages, costs, expenses
(including attorneys' fees and expenses), liabilities or judgments, fines or
amounts that are paid in settlement as a result of or in connection with any
threatened or actual action, suit or proceeding based on or arising out of the
fact that such person is or was a director or officer of the Company or any of
its Subsidiaries or out of or in connection with activities in such capacity,
whether pertaining to any matter existing or occurring at or prior to the
Effective Time and whether asserted or claimed prior to, or at or after, the
Effective Time ("Indemnified Liabilities"), including all Indemnified
Liabilities based on, or arising out of, or pertaining to this Agreement or the
transactions contemplated hereby, in each case to the full extent a corporation
is permitted under the DGCL to indemnify any such person and, without limiting
the generality or effect of the foregoing, to the fullest extent provided in the
Certificate of Incorporation or the Bylaws of the Company and its Subsidiaries
as in effect on the date hereof. The Parent will cause the Surviving Corporation
to pay expenses in advance of the final disposition of any such action or
proceeding to each Indemnified Party to the fullest extent permitted by law and,
without limiting

                                      38
<PAGE>
 
the generality or effect of the foregoing, to the fullest extent provided in the
respective Certificate of Incorporation or Bylaws of the Company and its
Subsidiaries as in effect on the date hereof subject to receipt by the Company
of an undertaking by or on behalf of such officer or director contemplated by
the DGCL. Without limiting the generality or effect of the foregoing, in the
event any such claim, action, suit, proceeding or investigation is brought
against any Indemnified Parties (whether arising before or after the Effective
Time) and, in the opinion of counsel to an Indemnified Party, under applicable
standards of professional conduct, there is a conflict on any significant issue
between the position of the Company and an Indemnified Party or different
defenses may reasonably be expected to exist, the Indemnified Parties may retain
counsel which counsel shall be reasonably satisfactory to the Company (or the
Surviving Corporation after the Effective Time) and the Company shall (or after
the Effective Time, Parent will cause the Surviving Corporation to) pay all
reasonable fees and expenses of such counsel for the Indemnified Parties
promptly as statements therefor are received, provided, however that (i) Parent
or the Surviving Corporation shall have the right, from and after the Effective
Time, to assume the defense thereof (which right shall not affect the right of
the Indemnified Parties to be reimbursed for separate counsel as specified in
the preceding sentence), (ii) the Company and the Indemnified Parties will
cooperate in the defense of any such matter and (iii) neither Parent, the
Company nor the Surviving Corporation shall be liable for any settlement
effected without its prior written consent. Any Indemnified Party wishing to
claim indemnification under this Section 6.2, upon learning of any such claim,
action, suit, proceeding or investigation, shall promptly notify both the Parent
and the Company (or, after the Effective Time, the Surviving Corporation) (but
the failure to so notify shall not relieve a party from any liability which it
may have under this Section 6.2 except and only to the extent such failure
materially prejudices such party), and shall deliver to both the Parent and the
Company (or after the Effective Time, the Surviving Corporation) the undertaking
contemplated by the DGCL. The Indemnified Parties as a group may not retain more
than one counsel to represent them with respect to each such matter unless there
is, in the opinion of counsel to an Indemnified Party, under applicable
standards of professional conduct, a conflict on any significant issue between
the positions of any two or more Indemnified Parties or unless different
defenses may reasonably be expected to exist. The Company, Parent and Merger Sub
agree that all rights to indemnification including provisions relating to
advances of expenses incurred in defense of any action or suit, existing in
favor of the Indemnified Parties with respect to matters occurring through the
Effective Time, shall survive the Merger and shall continue in full force and
effect for a period of not less than six years from the Effective Time;
provided, however, that all rights to indemnification in respect of any
Indemnified Liabilities asserted or made within such period shall continue until
the disposition of such Indemnified Liabilities.

          (c) The Parent agrees that the Company, and from and after the
Effective Time, the Surviving Corporation shall cause to be maintained in effect
for not less than six years (except as provided in the last sentence of this
Section 6.2(c)) from the Effective Time the current policies of the directors'
and officers' liability insurance maintained by the Company; provided that the
Surviving Corporation may substitute therefor other policies of at least the
same coverage amounts and which contain terms and conditions not less
advantageous (other than to a de minimus extent) to the beneficiaries of the
current policies and provided that such substitution shall not result in any
gaps or lapses in coverage with respect to matters occurring prior to the
Effective Time; and

                                      39
<PAGE>
 
provided, further, that the Surviving Corporation shall not be required to pay
an annual premium in excess of 200% of the last annual premium paid by the
Company prior to the date hereof and if the Surviving Corporation is unable to
obtain the insurance required by this Section 6.2(c) it shall obtain as much
comparable insurance as possible for an annual premium equal to such maximum
amount.

          (d) The Parent shall guarantee the obligations of the Surviving
Corporation under this Section 6.2.

          (e) This Section 6.2 shall survive the consummation of the Merger at
the Effective Time, is intended to benefit the Company, the Surviving
Corporation and the Indemnified Parties, shall be binding on all successors and
assigns of Parent and the Surviving Corporation and shall be enforceable by the
Indemnified Parties.

     6.3 Certain Benefit Plans.

          (a) Parent agrees that the Company will honor and, from and after the
Effective Time, it will cause the Surviving Corporation to honor all obligations
under Employee Benefit Plans and all employment agreements entered into by the
Company prior to the date hereof; provided, however, that nothing in this
Agreement shall be interpreted as limiting the power of Parent or the Surviving
Corporation to amend or terminate any such Employee Benefit Plan or as requiring
the Parent or the Surviving Corporation to offer to continue (other than as
required by its terms) any written employment contract so long as any such
action shall not adversely affect the rights or benefits of any employees or
other beneficiaries which shall have arisen thereunder prior to such amendment
or termination and shall not affect any rights or benefits for which the
agreement of the other party or a beneficiary is required as a condition to any
such amendment or termination. As soon as administratively practicable following
the Effective Time, Parent shall cause all employees of the Company then
actually at work to be covered under employee benefit and fringe benefit plans,
programs, policies and arrangements (including, without limitation, those which
provide medical, dental or life insurance benefits) that are no less favorable
than the employee benefit plans, programs, policies and arrangements that Parent
maintains for its similarly situated employees ("Parent-Provided Plans");
provided, that nothing in this sentence shall be deemed to limit or otherwise
affect the right of the Surviving Corporation to terminate the employment or
change the place of work, responsibilities, status or designation of any
employee of the Company as the Surviving Corporation may determine in the
exercise of its business judgment and in compliance with the terms of any
applicable employment or retainer agreement to which the Company or any of its
Subsidiaries is presently a party.

          (b) All service of an employee of the Company taken into account prior
to the Effective Time under any Employee Benefit Plan shall, on and after the
Effective Time, be taken into account as service with the Parent for purposes of
eligibility to participate and vesting under any similar Parent-Provided Plan.
Parent shall cause all Parent-Provided Plans to (i) waive any pre-existing
condition limitations otherwise applicable on and after the Effective Time to
the extent that such conditions are covered under the Company's Employee Benefit
Plans immediately prior to the Effective Time and (ii) provide that any expenses
incurred by the Company's employees

                                      40
<PAGE>
 
(and their dependents) during the plan year within which the Effective Time
occurs shall be taken into account for purposes of satisfying applicable
deductible, coinsurance and maximum out-of-pocket provisions (and like
adjustments or limitations on coverage) under the Parent-Provided Plans. Any
salary reduction elections of employees of the Company under a flexible spending
plan maintained by the Company pursuant to section 125 of the Code prior to the
Effective Time shall continue in effect under any similar Parent-Provided Plan
on and after the Effective Time, and any amounts credited and debited to
accounts of such employees under such Employee Benefit Plan as of the Effective
Time shall be credited and debited to such employees' accounts under such
Parent-Provided Plan.

     6.4 No Survival of Representations and Warranties. Except for the
provisions of Sections 2.9, 2.12, 2.13, 2.14, 2.18, 6.2, 6.3 and 8.3, and
Article 9, none of the representations, warranties, covenants, agreements and
certifications contained herein shall survive the Effective Time.

     6.5 Company Rights Plan. The Company shall make no further amendments to or
modifications of the Company Rights Agreement, or adopt any similar rights
agreement, from and after the date of this Agreement without the prior written
consent of Parent.

     6.6 Consents. The Company will use its reasonable best efforts to obtain
the consents under the contracts listed in Section 4.28 of the Company
Disclosure Letter.

     6.7 Potential Claims. The Company and Parent each agree to use their
reasonable best efforts to resolve any actions, suits, claims, litigation, or
proceedings instituted or threatened by any Governmental Entity or otherwise
against any of the parties hereto which would give rise to the occurrence of any
of the events specified in paragraph (a) or (b) of Annex A to this Agreement.

respective obligation of each party to consummate and effect the Merger shall be
subject to the satisfaction prior to or at the Closing as hereinafter provided

Law:

          (a) Regulatory Approvals. Clearance from the appropriate agencies,

                                      41
<PAGE>
 
          (b) Approval of Stockholders. This Agreement, the Merger and the
transactions contemplated by this Agreement shall, if necessary, have received
the requisite approval and authorization of the Stockholders in accordance with
applicable Law and the Certificate of Incorporation and Bylaws of the Company.

          (c) Statutes, Court Orders. No statute, rule or regulation shall have
been enacted or promulgated by any Governmental Entity which prohibits the
consummation of the Merger; and there shall be no order or injunction of a court
of competent jurisdiction in effect precluding consummation of the Merger.

          (d) Purchase of Company Common Stock in Offer. Parent, Merger Sub or
their Affiliates shall have purchased Company Common Stock pursuant to the
Offer, except that this condition shall not apply if Parent, Merger Sub or their
Affiliates shall have failed to purchase Company Common Stock pursuant to the
Offer in breach of their obligations under this Agreement.

     7.2 Conditions to the Parent's and Merger Sub's Obligation to Effect the
Merger. The obligations of the Parent and Merger Sub to consummate the Merger

hereto shall have been taken, which may be waived in whole or part by the Parent
or Merger Sub and that the representations and warranties of the Company in
Section 4.28 shall have been true when made and shall be true as of the
Effective Time.


                                   ARTICLE 8

                       TERMINATION, WAIVER AND AMENDMENT

     8.1 Termination. This Agreement may be terminated and the Merger and
transactions contemplated by this Agreement may be abandoned at any time prior
to the Effective Time (whether before or after the approval of this Agreement by
the Stockholders), as follows:

          (a) by mutual written consent of the Company and the Parent;

          (b) by either of the Parent or the Company:

               (i) if (x) the Offer shall have expired without any Company
Common Stock being purchased therein or (y) Merger Sub shall not have accepted
for payment all Company Common Stock tendered pursuant to the Offer by September
30, 1999; provided, however, that the right to terminate this Agreement under
this Section 8.1(b)(i) shall not be available to any party whose failure to
fulfill any obligation under this Agreement has been the cause of, or resulted
in, the failure of Parent or Merger Sub, as the case may be, to purchase the
Company Common Stock pursuant to the Offer on or prior to such date; or

                                      42
<PAGE>
 
               (ii) if any Governmental Entity shall have issued an order,
decree or ruling or taken any other action (which order, decree, ruling or other
action the parties hereto shall use their reasonable efforts to lift), which
permanently restrains, enjoins or otherwise prohibits the acceptance for payment
of, or payment for, Company Common Stock pursuant to the Offer or the Merger and
such order, decree, ruling or other action shall have become final and non-
appealable.

          (c)  by the Company:

               (i) if Parent, Merger Sub or any of their Affiliates shall have
failed to commence the Offer on or prior to five business days following the
date of the initial public announcement of the Offer; provided, that the Company
may not terminate this Agreement pursuant to this Section 8.1(c)(i) if the
Company is at such time in breach of its obligations under this Agreement;

               (ii) upon the execution of a definitive agreement for an
Acquisition Transaction that the Board shall have decided to recommend to the
Stockholders after the Board has reasonably concluded, after consultation with
its outside independent counsel, that such Acquisition Transaction constitutes a
Superior Proposal and that its failure to make such recommendation and terminate
this Agreement could violate the Board's fiduciary duties under applicable Law,
provided (A) it has complied with all provisions of Section 3.4, including the
notice provisions therein, (B) that it has paid or made arrangements reasonably
satisfactory to Parent to pay promptly (and, in any event, within five (5)
business days of the termination of this Agreement) the amounts referred to in
Section 8.3 hereof and (C) it shall have provided to Parent at least five
business days' prior written notice that the Board intends to terminate this
Agreement pursuant to this Section 8.1(c)(ii), specifying the material terms and
conditions of such Acquisition Transaction. In connection with the foregoing,
the Company agrees that it will

               (X) not enter into a binding agreement with respect to an
          Acquisition Transaction until at least the sixth business day after it
          has provided the notice to Parent required hereby,

               (Y) consider in good faith any offer made by Parent during that
          period, and

               (Z) notify Parent promptly if its intention to enter into such an
          agreement shall change at any time after such notification; or

               (iii) if Parent or Merger Sub shall have breached in any material
respect any of their respective representations, warranties, covenants or other
agreements contained in this Agreement, which breach cannot be or has not been
cured, in all material respects, within 30 days after the giving of written
notice to Parent or Merger Sub, as applicable.

                                      43
<PAGE>
 
          (d)  by Parent:

               (i) if, due to an occurrence, not involving a breach by Parent or
Merger Sub of their obligations hereunder, which makes it impossible to satisfy
any of the conditions set forth in Annex A hereto, Parent, Merger Sub, or any of
their affiliates shall have failed to commence the Offer on or prior to five
business days following the date of the initial public announcement of the
Offer;

               (ii) if prior to the purchase of Company Common Stock pursuant to
the Offer, the Company shall have breached any representation, warranty,
covenant or other agreement contained in this Agreement (other than those
contained in Section 3.4) which (A) would give rise to the failure of a
condition set forth in paragraph (f) or (g) of Annex A hereto and (B) cannot be
or has not been cured, in all material respects, within 30 days after the giving
of written notice to the Company;

               (iii) if either Parent or Merger Sub is entitled to terminate the
Offer as a result of the occurrence of any event set forth in paragraph (e) of
Annex A hereto; or

               (iv) if there has been a material breach of Section 3.4 of this
Agreement which, if capable of being cured, has not been cured within 10 days.

     8.2 Rights on Termination. In the event of termination and abandonment of
the Merger by any party pursuant to Section 8.1, written notice thereof shall
forthwith be given to the other parties and this Agreement shall terminate and
the Merger and the other transactions contemplated hereby shall be abandoned,
without further action by any of the parties hereto. If this Agreement is
terminated and the transactions contemplated hereby are not consummated pursuant
to Section 8.1 of this Agreement, this Agreement shall become void and of no
further force and effect, except for (a) the provisions of Section 3.1 relating
to the obligation of the Parent and Merger Sub to keep confidential and not to
use certain information obtained from the Company and (b) the provisions of
Section 8.3 relating to the Company's obligations to make certain payments to
the Parent.

     8.3 Termination Fee Payable to the Parent. Notwithstanding any provision to
the contrary contained herein, the Company shall immediately pay to the Parent
(x) the amount of $11.0 million and (y) all actual documented out-of-pocket
expenses reasonably incurred by the Parent and Merger Sub in connection with
this Agreement and the Merger in an amount not to exceed $2.0 million (the
"Termination Expenses") if this Agreement is terminated: (1) by the Company
pursuant to Section 8.1(c)(ii), (2) by Parent pursuant to Section 8.1(d)(iii) if
within six (6) months after such termination an Acquisition Transaction shall be
consummated or (3) by either the Company or Parent pursuant to Section 8.1(b)(i)
and (a) within six (6) months thereafter there shall be publicly announced
another Acquisition Transaction or prior thereto an event set forth in paragraph
(h) of Annex A shall have occurred (the "Expiration Date") and (b) an
Acquisition Transaction shall be consummated prior to the Expiration Date, or an
event set forth in paragraph (h) of Annex A shall have occurred, as the case may
be. In the event that this Agreement is terminated by Parent pursuant to Section
8.1(d)(iv), the Company shall immediately

                                      44
<PAGE>
 
pay Parent the Termination Expenses. In the event that the Company becomes
obligated to make the payment described in the preceding sentence and another
Acquisition Transaction is consummated within six (6) months after termination
by the Parent, the Company shall also pay to Parent the amount in (x) above.
Notwithstanding any provision to the contrary contained herein, the Company
shall immediately pay to the Parent, the Termination Expenses, if this Agreement
is terminated by Parent pursuant to Section 8.1(d)(ii) if the breach thereof is
due solely to the Company's intentional or bad faith acts. The amount in (x)
above shall be paid concurrently with any such termination and the Termination
Expenses shall be paid within five (5) business days after receipt by the
Company of reasonably detailed evidence of the same. Upon receipt of such
payments, Parent shall not be entitled to and shall waive the right to seek
damages or other amounts or remedies from the Company for breach of, or
otherwise in connection with, this Agreement, other than in the case of
termination by Parent pursuant to Section 8.1(d)(ii).

     8.4 Other Remedies. Notwithstanding any provision to the contrary contained
herein, if this Agreement is terminated pursuant to Article 8 or otherwise by
the Company, on the one hand, or Parent or Merger Sub, on the other hand, and
the non-terminating party is not entitled to receive the payments described in
Section 8.3 (as the case may be) or if Parent terminates this Agreement pursuant
to Section 8.1(d)(ii)), then the non-terminating party shall be entitled to
pursue any available legal rights to recover actual damages (not to exceed $5.0
million in respect of claim following a termination by Parent pursuant to
Section 8.1(d)(ii)), including, without limitation, its reasonable costs and
expenses incurred in pursuing such recovery (including, without limitation,
reasonable attorneys' fees).

     8.5 Notice of Termination. Any termination of this Agreement under Section
8.1 above will be effective immediately upon the delivery of written notice of
the terminating party to the other parties hereto upon satisfaction of the
requirements set forth in Section 8.1.

party contained herein or in any document delivered pursuant hereto and (iii)

The failure by Parent or Merger Sub at any time to exercise any of the foregoing
rights shall not be deemed a waiver of any such right and each such right shall
be deemed an ongoing right which may be asserted at any time and from time to
time.

          (a)  Section 8 of the Termination Agreement is amended in its entirety

          "8.  Termination by the Company Without Cause and Termination by
               Executive for Good Reason During the Extended Employment Period

          Upon an Executive's Date of Termination during the Extended Employment
     Period by the Company without Cause (other than for non-renewal of the Term
     of the Employment Agreement) or voluntarily by the Executive for Good
     Reason, the Term of this Termination Agreement will immediately terminate
     and all obligations of the Company and Executive under Sections 1 through 5
     of this Termination Agreement and under the Employment Agreement will
     immediately cease; provided, however, that subject to the provisions of
     Section 13(c) the Company shall pay Executive (or his or her
     beneficiaries), and Executive (or his or her beneficiaries) shall be
     entitled to receive, the following:

          (a)  the Company shall pay to the Executive in a lump sum in cash
     within thirty (30) days after the Date of Termination the aggregate of the
     following amounts:

               (i)    the sum of (1) the Executive's Annual Base Salary through
                      the Date of Termination to the extent not theretofore
                      paid, and (2) the product of (x) ____________ percent
                      (__%) of the Executive's Annual Base Salary ("Highest
                      Annual Bonus") and (y) a fraction, the numerator of which
                      is the number of days in the current fiscal year through
                      the Date of Termination, and the denominator of which is
                      365;

               (ii)   the amount equal to the product of (1) three and (2) the
                      sum of (x) the Executive's Annual Base Salary and (y) the
                      Highest Annual Bonus;

               (iii)  an amount equal to the actuarial equivalent (determined in
                      accordance with the provisions of the SERP) of the benefit
                      under the SERP which the Executive would receive assuming
                      for this purpose that the Executive's employment continued
                      for three (3) years after the Date of Termination and
                      assuming that the Executive's compensation in each of the
                      three years is that required by Section 3 of the
                      Termination Agreement plus the Executive's Highest Annual
                      Bonus;

               (iv)   in lieu of any payment in respect of performance shares,
                      or other long term incentive awards (including awards of
                      phantom shares

                      accordance with Section 4(a) of the Termination Agreement,
                      for any performance period not completed at the
                      Executive's Date of Termination, an amount equal to the
                      cash amount payable plus the value of any shares of Common
                      Stock or other property (valued at the Date of
                      Termination) payable upon the achievement of maximum
                      performance (or in the case of phantom shares, target
                      performance under the EBP) in respect of each tranche of
                      such performance shares or awards without proration as if
                      the Date of Termination were the end of the performance
                      period;

               (v)    a cash amount will be paid equal to the value at the Date
                      of Termination of any phantom shares of Common Stock
                      credited to Executive's deferral accounts under deferral
                      arrangements authorized under the Employment Agreement at
                      the Date of Termination, less applicable withholding taxes
                      under Section 14(i) of the Employment Agreement; provided,
                      however, that the Company may instead settle such accounts
                      by directing the Trustee to distribute the assets of the
                      "rabbi trust" and the Company shall be relieved of its
                      obligation under this Employment Agreement and the
                      Termination Agreement to the extent that assets are so
                      distributed. Such amounts shall be paid or distributed as
                      promptly as practicable following such Date of
                      Termination, without regard to any stated period of
                      deferral otherwise remaining in respect of such amounts,
                      and the payment of such amounts shall be deemed to fully
                      settle such accounts; and

               (vi)   to the extent not covered in (i), (ii), (iii), (iv) or
                      (v), all vested, nonforfeitable amounts owing or accrued
                      at the Date of Termination under any other compensation
                      and benefit plans, programs, and arrangements in which
                      Executive theretofore participated will be paid under the
                      terms and conditions of the plans, programs, and
                      arrangements (and agreements and documents thereunder)
                      pursuant to which such compensation and benefits were
                      granted.

          (b) Stock options then held by the Executive will be exercisable and
     restricted stock held by the Executive will be vested to the extent and for
     such periods, and otherwise governed, by the plans and programs (and the
     agreements and other documents thereunder) pursuant to which such stock
     options or restricted stock were granted; provided, however, that the stock
     options and restricted stock described in Section 5 of the Employment
     Agreement shall be fully vested and shall be exercisable to the extent and
     for such periods, and otherwise governed by, the provisions of Section 5 of
     the Employment Agreement.

          (c) For three (3) years after the Executive's Date of Termination, or
     such longer period as may be provided by the terms of the appropriate plan,
     program, practice or policy, the Company shall continue Welfare Plan
     Benefits to the Executive and/or the Executive's family at least equal to
     those which would have been provided to them in accordance with the plans,
     programs, practices and policies described in Section 4(b) of the
     Termination Agreement if the Executive's employment had not been terminated
     or, if more favorable to the Executive, as in effect generally at any time
     thereafter with respect to other peer executives of the Company and its
     affiliated companies and their families, provided, however, that if the
     Executive becomes reemployed with another employer and is eligible to
     receive medical or other welfare benefits under another employer-provided
     plan, the medical and other welfare benefits described herein shall be
     secondary to those provided under such other plan during such applicable
     period of eligibility. If such plans, programs, or arrangements do not
     allow Executive's continued participation, a cash payment equivalent on an
     after-tax basis to the value of the additional benefits Executive would
     have received under such employee benefit plans, programs, and arrangements
     in which Executive was participating immediately prior to the Date of
     Termination, as if Executive had received credit under such plans,
     programs, and arrangements for service and age with the Company during such
     period following Executive's Date of Termination, with such benefits
     payable by the Company at the same times and in the same manner as such
     benefits would have been received by Executive under such plans (it being
     understood that the value of any insurance-provided benefits will be based
     on the premium cost to Executive, which shall not exceed the highest risk
     premium charged by a carrier having an investment grade or better credit
     rating); and

          (d) outplacement services the scope and provider of which shall be
     selected by the Executive in his sole discretion, provided by the Company
     at its sole expense as incurred."

          (b) The last sentence of Section 9(e) of the Termination Agreement is
amended in its entirety to read as follows:

     "For purposes of this Section, (i) the Executive shall be deemed to
     terminate employment for "Good Reason" in the event the Executive separates
     from employment with the Company within a period of thirty (30) days
     following the date six (6) months after a Change of Control, and (ii) any
     good faith determination of "Good Reason" otherwise made by the Executive
     shall be conclusive."

     4. Application of the Termination Agreement. Except as provided herein, the
Termination Agreement shall remain in full force and effect.

                              [WALBRO LETTERHEAD]

         Walbro Corporation Enters Into Merger Agreement with TI Group

AUBURN HILLS, Michigan -- Walbro Corporation, (NASDAQ: WALB) based in Auburn
Hills, Michigan, announced today that it has entered into a definitive merger
agreement with TI Group plc, headquartered in London, England, pursuant to which
Walbro will become a wholly-owned subsidiary of TI Group.  The all-cash
transaction of $20.00 per share values Walbro at $570 million and is subject to
customary regulatory approvals.  The Board of Directors of both companies have
unanimously approved the merger agreement and will be effected through a tender
offer launched by TI Group.

Walbro is a global leader in the automotive and small engine fuel storage and
delivery systems and components business with 1998 sales of $680 million.
Walbro has a number of joint ventures with sales of $210 million.

TI Group is a $3.5 billion (sales) global specialized engineering company with
four world leader businesses:  John Crane (engineered sealing systems), Forsheda
(engineered elastomer seals), Bundy (fluid carrying systems) and Dowty
(aerospace systems).  TI will combine its existing Bundy automotive fuel
business with Walbro to create a strong global position in supplying complete
automotive fuel storage and delivery systems.  Walbro has operations in 15
countries while TI's Bundy business operates in 27 countries.

Sir Christopher Lewinton, Chairman of TI Group, commented, "This attractive
acquisition is consistent with the strategy TI Group has followed over a number
of years and I am very pleased that, on completion, it will enable TI to form a
new TI Automotive Systems group of which Bundy and Walbro will be key
businesses.  I am confident that the combination of these two businesses within
TI Automotive Systems will accelerate growth of this important part of the
Group."

The new TI Automotive Systems group will have important positions in three key
fluid handling automotive markets for brake, fuel and powertrain systems.  The
combined revenues of this new group in 1998 would have been approximately $2.0
billion.

On completion of the transaction, Frank Bauchiero, President and CEO of Walbro,
will report to Bill Laule, Chief Executive of TI Group in England.

Walbro consists of two businesses:  a $530 million automotive fuel storage and
delivery systems business and a $150 million fuel systems business for small
engines.  The $530 million automotive fuel systems business is complementary to
TI's existing $375 million Bundy fuel delivery systems business consisting of
rigid and flexible lines and quick connectors.

Mr. Bauchiero commented, "We are very pleased that our mutual efforts have
resulted in a merger agreement which offers significant benefits to
stockholders, customers, employees and joint venture partners, as well as to the
communities where we are located.  We believe that this
<PAGE>
 
combination with TI strengthens the global reach of both companies and offers
current and potential customers of both businesses an impressive array of
products and systems that enjoy strong market positions. Moreover, the
respective cultures of both companies are very similar. We believe that merging
these talents will have a positive, synergistic effect on the competitiveness of
the combined company."

Bill Laule, Chief Executive Officer of TI Group, commented, "I am delighted that
we are able to make this recommended offer for Walbro.  With the strong
strategic fit and sustained investment in new facilities, this acquisition now
gives us the opportunity to continue Walbro's strong record of sales growth,
enhance its margins and deliver increased profitability and cash generation.
The creation of a uniquely positioned TI Automotive Systems group, capable of
supplying a completely integrated fuel storage and delivery system on a global
basis, moves the business further up the added value chain.  The enlarged market
that will now be served by us provides great potential for accelerated growth
and ideally positions TI Automotive Systems to enjoy even greater success in the
future, and contribute to improved shareholder value."

Walbro Corporation was advised in this transaction by the investment banking
firm of Salomon Smith Barney Inc. and the law firm of Katten Muchin & Zavis.

Walbro Corporation is a designer and manufacturer of precision fuel systems and
products for automotive and small engine markets.  Walbro Corporation has
subsidiaries and joint ventures throughout the world, including North and South
America, Europe and Asia.  Walbro common stock is traded on the Nasdaq National
Market under the symbol WALB.
