                                __________, 1999

To Our Shareholders:

         We invite you to attend a special meeting of the shareholders of
Worthington Foods, Inc. ("Worthington") to be held at 10:00 a.m., local time, on
November __, 1999, at ____________________, ____________________, Columbus,
Ohio.

         The purpose of the special meeting is to vote upon the merger of a
wholly-owned subsidiary of Kellogg Company ("Kellogg") into Worthington pursuant
to a merger agreement which the parties entered into on September 30, 1999. If
the merger is approved by our shareholders, Worthington will become a
wholly-owned subsidiary of Kellogg and the shareholders of Worthington will
receive $24 in cash for each common share owned by them.

         Your board of directors has carefully reviewed and considered the terms
and conditions of the proposed merger. It has also received a written opinion,
dated September 30, 1999 and confirmed as of the date of this letter, from U.S.
Bancorp Piper Jaffray Inc., our financial advisor, that the $24 merger price was
fair to our shareholders from a financial point of view as of the date of the
opinion. A copy of the U.S. Bancorp Piper Jaffray Inc. opinion is included as
Appendix B to the accompanying proxy statement.

         Based on its review of the merger, the board of directors has
determined that the merger is fair and in the best interests of Worthington and
our shareholders. The board of directors unanimously recommends that you vote
"FOR" adoption of the merger agreement and approval of the merger.

         You are urged to read the details of the proposed merger and other
material information contained in the accompanying proxy statement.

         The holders of at least a majority of our outstanding common shares
must vote in favor of the merger agreement for its approval. As a result, your
failure to vote will have the same effect as a vote against the adoption of the
merger agreement. Your vote is therefore very important. We urge you to
complete, sign and date the enclosed proxy or voting instruction card and return
it in the enclosed return envelope, whether or not you plan to attend the
special meeting. If you do attend the special meeting and wish to vote in
person, you may withdraw your proxy and vote in person.

         Please do not send any share certificates at this time. You will
receive instructions regarding the surrender of your share certificate(s) and
receive payment for your common shares after the effective time of the merger.

         Worthington will no longer be publicly held, and its common shares will
         no longer be traded on The Nasdaq National Market.

Q:       Why did the Board approve the merger agreement and merger?

A:       The Board considered a number of factors in approving the merger

            over the per share closing prices on September 30, 1999, the last
            trading day prior to the date of public announcement of the merger

            analyses presented by U.S. Bancorp Piper Jaffray Inc.;

         -  historical market prices of Worthington's common shares;

         -  the terms and conditions of the merger agreement, including the
            right of the board of directors to terminate the merger agreement

            merger with Kellogg; and

         -  various other factors, as described in "The Merger--Worthington's
            Reasons for the Merger; Recommendation of the Board."

Q:       What will I receive for my common shares after the merger is completed?

A:       Each shareholder (except for shareholders who have properly exercised
         dissenters' rights under Ohio law) will be entitled to receive $24 in
         cash for each common share held by them at the effective time of the
         merger.

Q:       What do I need to do now?

A:       Just mail your signed and completed proxy card in the enclosed return
         envelope as soon as possible, so that your common shares can be voted
         at the special meeting.

                                       7
<PAGE>   11

Q:       If my common shares are held in "street name" by my broker, will my
         broker vote my common shares for me?

A:       Your broker will vote your common shares only if you provide
         instructions on how to vote. You should contact your broker and ask
         what directions your broker will need from you. Your broker will not be
         able to vote your common shares without instructions from you.

Q:       Can I change my vote after I have mailed my signed proxy card?

A:       Yes. You can change your vote at any time before your proxy is voted at
         the special meeting. You can do this in one of three ways. First, you
         can attend the special meeting and vote in person. Your attendance
         alone will not, however, revoke your proxy. If you have instructed a
         broker to vote your common shares, you must follow directions received
         from your broker to change those instructions. Second, you can complete
         and submit a new proxy card. Third, you can send a written notice
         stating that you would like to revoke your proxy.

Q:       Should I send in my share certificates now?

A:       No. After the merger is completed, you will receive written
         instructions for delivering your certificates for your common shares
         for the cash payment.

Q:       What happens to my future dividends?

A:       We plan to continue paying dividends on our common shares until the
         closing of the merger. We expect to pay these future dividends at
         approximately the same time and rate per share as we have paid during
         the last year.

Q:       Do I have dissenters' rights for my common shares if the merger is
         completed?

A:       Yes. If you wish to exercise your dissenters' rights, you must not vote
         in favor of the adoption of the merger agreement and you must follow
         the procedures described in this proxy statement. If you comply with
         these procedures, you will have the right to receive the "fair cash
         value" of your common shares, as determined under the Ohio law
         governing dissenters' rights, instead of the $24 per share as provided
         in the merger. The amount you will receive if you exercise your
         dissenters' rights may be equal to, more than or less than $24 per
         share.

Q:       What will happen if Worthington's shareholders do not adopt the merger
         agreement?

A:       If Worthington's shareholders do not adopt the merger agreement,
         management and the Board will continue to operate Worthington as
         before, and may consider other strategic alternatives. However, if
         Worthington receives an alternative proposal prior to termination of
         the merger agreement and then enters into an agreement to sell
         Worthington with another party within one year after the termination of
         the merger agreement, Worthington may be required to pay Kellogg a
         termination fee of $12.5

                                       8
<PAGE>   12

         million and an amount up to $500,000 constituting reimbursement of the
         expenses of Kellogg incurred in connection with the proposed merger.

Q:       What happens if I do not send in my proxy card, if I do not instruct my
         broker, or if I abstain from voting?

A:       If you do not send in your proxy card, if you do not instruct your
         broker to vote your common shares, or if you abstain from voting, it
         will have the same effect as a vote against the adoption of the merger
         agreement.

Q:       What are the tax consequences of the merger to shareholders?

A:       In general, a shareholder will recognize gain or loss for federal
         income tax purposes to the extent of the difference between the cash
         received and the holder's tax basis in the common shares exchanged for
         cash.

Q:       What regulatory approvals are needed?

A:       Before the merger can be completed, we must, among other things, await
         the expiration or termination of the waiting period under the
         Hart-Scott-Rodino Antitrust Improvements Act of 1976.

Q:       What other conditions are there to the completion of the merger?

A:       The merger may not be completed if certain conditions are not met or
         otherwise waived, including, but not limited to:

         -        Worthington's shareholders do not adopt the merger agreement.

         -        There is a material breach of any covenant, representation or
                  warranty of Worthington or Kellogg in the merger agreement and
                  such breach is not curable or is not cured within a 30-day
                  period.

         -        The merger is not completed by March 31, 2000.

         -        Other specified conditions are not satisfied, as described in
                  "Terms of the Merger Agreement--Conditions to the Merger."

Q:       When do you expect the merger to be completed?

A:       We hope to complete the merger by the end of 1999. We are working
         toward completing the merger as quickly as possible, and to the extent
         that the regulatory approvals are received and other conditions are
         satisfied prior to that time, we intend to complete the merger earlier.
         However, the timing and likelihood of obtaining the regulatory
         approvals described above are uncertain.

Q:       Who can help answer my questions?

TERMS OF THE MERGER AGREEMENT

         Effective Time of the Merger. The parties expect that the effective
time of the merger will occur on the eleventh calendar day following the
satisfaction or waiver of the conditions to the merger contained in the merger
agreement. The merger will become effective at the time of the filing of a
certificate of merger with the Secretary of State of the State of Ohio.

         Certain Conditions to the Merger. Before the merger is consummated, a
number of conditions must be satisfied. These include:

         -        adoption of the merger agreement by the shareholders of
                  Worthington;

         -        the absence of any court order or law having the effect of
                  making illegal or otherwise prohibiting the consummation of
                  the merger;

         -        obtaining all required third party consents and approvals by
                  any governmental or regulatory authority;

         -        the rights to purchase Series A Junior Participating Preferred
                  Shares issued under the Rights Agreement dated as of June 13,
                  1995, as amended, between Worthington and National City Bank,
                  as Rights Agent, have not become exercisable or transferable
                  apart from the associated common shares and the rights have
                  been redeemed under the terms of the Rights Agreement;

         -        the number of common shares held by persons who have exercised
                  dissenters' rights under Ohio law does not exceed 10% of the
                  total number of outstanding common shares;

         -        the representations and warranties made by each of the parties
                  in the merger agreement are true and correct in all material
                  respects; and

         -        other customary closing conditions.



                                       12
<PAGE>   16

         Where the law permits, Worthington or Kellogg could decide to complete
the merger even though one or more conditions was not satisfied. By law, neither
Worthington nor Kellogg can waive (a) the condition of approval of the merger
agreement by Worthington's shareholders or (b) any court order or law having the
effect of making illegal or otherwise prohibiting the consummation of the
merger. Whether any of the other conditions would be waived would depend upon
the facts and circumstances as determined by the reasonable business judgment of
the board of directors of Worthington or Kellogg.

         Manner and Basis of Converting Common Shares. At the effective time of
the merger, each issued and outstanding common share (other than common shares
that are canceled as described in this paragraph and common shares held by
shareholders who have properly exercised dissenters' rights under Ohio law) will
automatically be converted into the right to receive $24 in cash. This
conversion will occur by virtue of the merger and without any action on the part
of any holder of any capital stock of Worthington, Kellogg or WF Acquisition
Inc. Any common shares that Kellogg, WF Acquisition Inc. or any other
wholly-owned subsidiary of Kellogg holds, or that Worthington holds as treasury
shares, will be canceled and cease to exist, and no consideration will be
delivered or deliverable in exchange for those common shares. As of the date of
this proxy statement, neither Kellogg nor WF Acquisition Inc. or any other
subsidiary of Kellogg owned any common shares of Worthington, and Worthington
held no treasury shares.

         In order to receive the cash amount of $24 per share, shareholders of
Worthington must surrender for exchange their certificates representing their
common shares. Prior to the closing date of the merger, Kellogg will appoint a
bank or trust company to act as payment agent for the merger. At the closing of
the merger, Kellogg will deposit with the payment agent, in a fund established
for the benefit of the holders of common shares, for payment through the payment
agent, an amount of cash sufficient to pay to the shareholders of Worthington
the aggregate merger price.

         As soon as reasonably practicable after the effective time of the
merger, the surviving corporation will instruct the payment agent to mail to
each holder of record of a common share certificate immediately prior to the
effective time of the merger (i) a form of letter of transmittal and (ii)
instructions for surrendering the common share certificates in exchange for
payment of the merger price.

         Stock-Based Employee Benefit Plans. The merger agreement provides that,
immediately prior to consummation of the merger, all outstanding options to
purchase common shares granted under Worthington's 1985 Stock Option Plan, 1993
Stock Option Plan for Non-Employee Directors and Amended and Restated 1995 Stock
Option Plan, whether or not then exercisable, will be cancelled by Worthington
and, in consideration of such cancellation, each holder of an option will be
entitled to receive from Worthington at the effective time of the merger an
amount in respect thereof in cash equal to the product of the excess, if any, of
$24 over the per share exercise price of the option and the number of common
shares subject to the option. This payment is to be made net of applicable
withholding taxes. Prior to the effective time of the merger, Worthington will
deposit in a bank account not within Worthington's control an amount of cash
necessary to make such option cancellation payments, together with instructions
that



                                       13
<PAGE>   17

such cash be promptly distributed following the effective time of the merger to
the holders of such options.

         As of the effective time of the merger, Worthington will amend its Tax
Savings and Profit Sharing Plan to eliminate any investment fund comprised of
common shares, prohibit any additional contributions in the form of common
shares and make all participant accounts fully vested and nonforfeitable. In
addition, Worthington will amend its Employee Stock Ownership Plan as of the
effective time of the merger to provide that benefits will be distributed solely
in cash. Within 30 days of the effective time of the merger, Kellogg will cause
the surviving corporation in the merger to terminate the Employee Stock
Ownership Plan and, as soon as administratively practicable after such date, to
liquidate the plan by distributing its assets in accordance with the terms of
the plan.

         No Solicitation. The merger agreement restricts Worthington, its
subsidiary and Worthington's representatives generally from initiating,
soliciting or encouraging any other transaction that would result in a merger or
the purchase of 5% or more of the outstanding common shares or the capital
shares of Worthington's subsidiary or the sale of any significant portion of the
assets of Worthington and its subsidiary taken as a whole. See "Terms of the
Merger Agreement--No Solicitation."

         Termination of the Merger Agreement. The merger agreement may be
terminated at any time prior to the effective time of the merger:

         -        by mutual written agreement of Kellogg and Worthington;

         -        by either party if the merger has not been consummated by
                  March 31, 2000 (provided that the right to terminate will not
                  be available to any party whose breach of any obligation under
                  the merger agreement has been the cause of the failure to
                  consummate the merger on or before that date);

         -        by either party if the merger agreement is not adopted by
                  Worthington's shareholders;

         -        by either party if there has been a material breach of the
                  other party that is not curable or, if curable, has not been
                  cured within 30 days following notice;

         -        by either party if any court or other governmental or
                  regulatory authority issues a final order making the merger
                  illegal or otherwise restricting, preventing or prohibiting
                  the merger;

         -        by Worthington, if Worthington's board of directors determines
                  in good faith, based on advice of outside counsel, that
                  termination of the merger agreement is required for the board
                  to comply with its fiduciary duties to shareholders imposed by
                  law by reason of an unsolicited Alternative Proposal (as
                  defined in "Terms of the Merger Agreement--No Solicitation")
                  and Worthington pays to Kellogg a termination fee of $12.5
                  million and reimburses the merger expenses of Kellogg up to
                  $500,000; or

                                       14
<PAGE>   18

         -        by Kellogg, if Worthington's board of directors withdraws its
                  approval or recommendation of the merger agreement or merger,
                  modifies its approval or recommendation in a manner adverse to
                  Kellogg, recommends an Alternative Proposal to the
                  shareholders of Worthington or fails to reconfirm its
                  recommendation of the merger agreement and merger following
                  the written request of Kellogg.

         Termination Fees and Expenses. Worthington will be required to pay
Kellogg a termination fee of $12.5 million plus expenses of up to $500,000 if
any person or group has made an Alternative Proposal and the merger agreement is
thereafter terminated:

         -        by Worthington because Worthington's board of directors

                  -        has determined in good faith, based on advice of
                           outside counsel, that termination of the merger
                           agreement is required for the board to comply with
                           its fiduciary duties to shareholders imposed by law
                           by reason of an Alternative Proposal, and

                  -        has concluded, after consulting with its financial
                           advisors, that the Alternative Proposal is more
                           favorable to Worthington's shareholders than the
                           Kellogg merger, and the Alternative Proposal is not
                           conditioned on the receipt of financing and the board
                           of directors has received a "fairness opinion" from
                           an investment banking firm regarding the Alternative
                           Proposal;

         -        by Kellogg because Worthington's board of directors has
                  withdrawn its approval or recommendation of the merger or the
                  merger agreement, modified its approval or recommendation in a
                  manner adverse to Kellogg, recommends an Alternative Proposal
                  to the shareholders of Worthington or fails to reconfirm its
                  recommendation of the merger agreement and merger following
                  the written request of Kellogg;

         -        by Kellogg because there has been a material breach by
                  Worthington of any representation, warranty, covenant or
                  agreement of Worthington in the merger agreement, and an
                  agreement with respect to the Alternative Proposal is executed
                  within one year of the termination of the merger agreement;

         -        by either party because the merger has not been adopted by
                  Worthington's shareholders, and an agreement with respect to
                  the Alternative Proposal is executed within one year of the
                  termination of the merger agreement; or

         -        by either party because the merger has not been consummated by
                  March 31, 2000, and an agreement with respect to the
                  Alternative Proposal is executed within one year of the
                  termination of the merger agreement.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

         In considering the board of directors' recommendation that the
shareholders vote in favor of the adoption of the merger agreement, shareholders
should be aware that Worthington's executive officers and directors will receive
payments and other benefits as a result of the merger which result in their
having interests in the merger that are different from, or in addition to, the
interests of other shareholders. See "The Merger--Interests of Certain Persons
in the Merger." The board was aware of these interests and considered them,
among other things, in approving the merger agreement.

         Agreements with Executive Officers and Other Key Employees. Worthington
has in place change in control severance agreements with each of its seven
executive officers and two of its other key employees. The severance agreements
provide for severance and change in control benefits if qualifying terminations
of employment occur after a change in control of Worthington. The merger will
constitute a change in control under these severance agreements. On September
30, 1999, Kellogg entered into written agreements with these nine Worthington
employees who are parties to severance agreements with Worthington which will
become effective only upon the completion of the merger and which provide, among
other things, for the termination of all of the existing severance agreements
and the payment to these nine individuals following the merger of amounts that
approximate the payments that they would have received under their severance
agreements if they had a qualifying termination of employment following the
merger and the employment of six of these individuals by Kellogg for differing
periods of time following the completion of the merger. See "The
Merger--Interests of Certain Persons in the Merger."

         Stock Option Plans. Worthington has previously issued stock options to
its executive officers and directors under its various stock option plans. The
merger agreement provides that, immediately prior to the completion of the
merger, each option holder will be paid an amount in consideration of the
cancellation of his outstanding options (whether or not then exercisable) equal
to the product of the excess, if any, of $24 over the exercise price per share
of the options and the number of common shares subject to the options. Each
payment will be made net of applicable withholding taxes. Worthington has agreed
to use its reasonable best efforts and otherwise take all actions reasonably
necessary to implement the cash-out of the stock options in accordance with the
merger agreement.

         Indemnification and Continuation of Liability Insurance. The merger
agreement contains provisions with respect to indemnification of Worthington's
directors and officers after the merger and the continuation of director and
officer liability insurance for these individuals.

REGULATORY MATTERS

         Kellogg and Worthington have made pre-merger filings with U.S.
antitrust authorities under the Hart-Scott-Rodino Antitrust Improvements Act of
1976.

FEDERAL INCOME TAX CONSEQUENCES

         The receipt of cash for common shares pursuant to the merger or to the
exercise of dissenters' rights will be a taxable transaction for federal income
tax purposes and may also be a



                                       16
<PAGE>   20

taxable transaction under state, local and other tax laws. In general, a
shareholder will recognize gain or loss for federal income tax purposes to the
extent of the difference between the cash received and the holder's tax basis in
the common shares exchanged for cash. For a discussion of these and other
federal income tax considerations in connection with the merger, see "The
Merger--Federal Income Tax Consequences." Holders of common shares are urged to
consult their own tax advisors as to the tax consequences of the merger
particular to them, including the applicability and effect of state, local and
other tax laws.

DISSENTERS' RIGHTS

         If you object to the merger, Ohio law permits you to seek relief as a
dissenting shareholder and have the "fair cash value" of your common shares
determined by a court and paid to you in cash. To do this, you must satisfy each
of the following conditions:

         -        you must be a shareholder of Worthington on the record date
                  for the vote on the merger agreement;

         -        you must not vote dissenting shares in favor of adoption of
                  the merger agreement;

         -        you must deliver to Worthington a written demand for the fair
                  cash value of your common shares for which you exercise
                  dissenters' rights within ten days after the vote on the
                  merger agreement stating your name, address, the number of
                  common shares and the amount you claim is the fair cash value
                  of those common shares;

         -        if Worthington requests, you must deliver to Worthington the
                  certificates evidencing the common shares for which you
                  exercise dissenters' rights for endorsement of the legend that
                  demand for their fair cash value has been made; and

         -        within three months after your delivery to Worthington of your
                  written demand for payment of the fair cash value of the
                  common shares for which you exercise dissenters' rights, you
                  must file or join in a petition in the Court of Common Pleas
                  of Franklin County, Ohio for a determination of their fair
                  cash value unless you and Worthington have agreed on their
                  fair cash value.

You will not receive payment of the $24 merger price if you dissent and follow
all the required procedures. Instead, you will only receive the fair cash value
of your common shares for which you exercise dissenters' rights.

         For more information about the steps to be taken by Worthington
shareholders who wish to exercise their dissenters' rights, see "The
Merger--Rights of Dissenting Shareholders". The relevant section of Ohio law
governing this process is attached to this proxy statement as Appendix C.

                               THE SPECIAL MEETING

DATE, TIME AND PLACE

         The special meeting will be held on November __, 1999, at the
______________ ______________, Columbus, Ohio, commencing at [10:00] a.m., local
time.

PURPOSE OF THE SPECIAL MEETING

         The purpose of the special meeting is to consider and vote upon the
proposal to adopt the merger agreement. Worthington shareholders will also
consider and vote upon any other matters which properly come before the special
meeting.

RECORD DATE; QUORUM

         Only holders of record of common shares at the close of business on
____________, 1999 are entitled to notice of, and to vote at, the special
meeting. On ____________, 1999, there were approximately ______ holders of
record of the common shares issued and outstanding.

         Each common share entitles the holder to one vote on each matter
submitted for shareholder approval. See "Security Ownership of Certain
Beneficial Owners and Management of Worthington" for information regarding
persons known to Worthington to be the beneficial owners of more than 5% of the
outstanding common shares. The presence at the special meeting, in person or by
proxy, of the holders of a majority of the outstanding common shares entitled to
vote at the special meeting will constitute a quorum for the transaction of
business.

VOTING AND REVOCATION OF PROXIES

         A form of proxy card for use by shareholders at the special meeting
accompanies this proxy statement. All properly executed proxy cards that are
received prior to or at the special meeting and not revoked will be voted at the
special meeting in accordance with the instructions contained in the proxy
cards. If a holder of common shares executes and returns a proxy card and does
not specify otherwise, the common shares represented by the proxy card will be
voted "FOR" adoption of the merger agreement in accordance with the
recommendation of Worthington's board of directors. In such event, the holder of
those common shares will not have the right to dissent from the merger and
demand payment of the "fair cash value" of the holder's common shares.

         A properly executed proxy card marked "abstain" will count for
determining whether there is a quorum and for determining the aggregate voting
power and number of common shares represented and entitled to vote at the
special meeting. However, it will not be voted. Accordingly, since the
affirmative vote of the holders of at least a majority of the outstanding common
shares is required to adopt the merger agreement, a proxy card marked "abstain"
will have the effect of a vote "against" the adoption of the merger agreement.

                                       19
<PAGE>   23

         Under the rules of The Nasdaq National Market, brokers and nominees who
hold shares in their names but are not the beneficial owners of the shares may
not exercise voting discretion with respect to these shares. Thus, brokers and
nominees may not vote common shares held by them absent specific instructions
from the beneficial owners of the common shares. Since the affirmative vote of
at least a majority of the outstanding common shares is required to adopt the
merger agreement, a broker non-vote proxy card will have the effect of a vote
"against" the adoption of the merger agreement.

         A shareholder of Worthington who has executed and returned a proxy card
may revoke it at any time before it is voted at the special meeting by executing
and returning a proxy card bearing a later date, filing written notice of
revocation with the Secretary of Worthington stating that the proxy card is
revoked or attending the special meeting and voting in person.

VOTE REQUIRED; BOARD RECOMMENDATION

         Adoption of the merger agreement requires the affirmative vote of the
holders of at least a majority of the outstanding common shares. YOUR BOARD OF
DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE IN FAVOR OF THE MERGER AGREEMENT.

COST OF SOLICITATION OF PROXIES; MAILING DATE

         In addition to solicitation by mail, the directors, officers, employees
and agents of Worthington may solicit proxies from the shareholders of
Worthington by personal interview, telephone, telegram or otherwise. Worthington
will bear the costs of the solicitation of proxies from its shareholders.
Arrangements will also be made with brokerage firms and other custodians,
nominees and fiduciaries who are record holders of common shares for the
forwarding of solicitation materials to the beneficial owners of the common
shares. Worthington will reimburse these brokers, custodians, nominees and
fiduciaries for the reasonable out-of-pocket expenses incurred by them in

BACKGROUND

         The prepared food industry in general and the health-oriented segment
of that industry in particular have been undergoing significant changes in
recent years as a result of the increasing cost of developing and introducing
new products, growing technology costs, the need to market products on an
international basis, consolidation in the supermarket industry and other trends.
These changes have caused smaller prepared food companies such as Worthington to
reevaluate their future strategy and options. Over the past three years, the
board of directors and senior management of Worthington have considered the
company's business prospects as a stand-alone company, including the anticipated
short-term and long-term value to its shareholders of remaining an independent
company as well as the business risks associated with remaining independent.
During the past three years, Worthington has been approached by several large
food companies with an interest in pursuing a possible business combination. In
the course of evaluating these expressions of interest, Worthington's board of
directors and management have spent a considerable amount of time evaluating the
advantages and disadvantages of remaining an independent company versus
operating as part of a much larger food company.

         On July 8, 1999, Stephen Benoit, Vice President of Kellogg, telephoned
Dale Twomley, the Chairman, President and Chief Executive Officer of
Worthington, and indicated that Kellogg would like to discuss a possible
business relationship between the two companies. He said that Kellogg would be
willing to consider a wide range of possible relationships or transactions,
including a joint venture, a co-branding relationship or a purchase of the
Worthington business. He indicated that Kellogg intended to enter the meat
substitute category, and viewed Worthington as the leader in that

                                       21
<PAGE>   25
product category. He asked Mr. Twomley whether he would be willing to meet with
representatives of Kellogg's Natural and Functional Foods Division to discuss a
possible business relationship. Mr. Twomley responded that the board of
directors of Worthington was not looking for a buyer and that, based on the
board's expectation for strong future growth in revenues and earnings, any sale
of Worthington would require a substantial purchase price. He also told Mr.
Benoit that Worthington had little, if any, interest in pursuing a joint venture
or co-branding arrangement. Mr. Benoit reiterated Kellogg's interest in
discussing a possible transaction or arrangement between the companies and said
that he still would like the opportunity to meet to discuss the possibilities.
Mr. Twomley agreed to meet with Mr. Benoit and several other representatives of
Kellogg at Worthington's offices on July 16, 1999.

         On Friday, July 16, 1999, Mr. Benoit and several other representatives
of Kellogg met with Mr. Twomley, William Kirkwood, Worthington's Executive Vice
President and Chief Financial Officer, and Ronald McDermott, Worthington's Vice
President of Research and Technology. Prior to that meeting, Kellogg and
Worthington had entered into a confidentiality agreement. At the meeting, the
Worthington representatives reviewed with Kellogg information which they had
previously provided to securities analysts and shareholders. By the end of the
meeting, the parties agreed to continue discussion of a possible acquisition of
Worthington by Kellogg. Mr. Twomley agreed that he would discuss Kellogg's
interest in an acquisition with the Worthington board of directors.

         At a regularly-scheduled meeting of the board of directors of
Worthington on July 20, 1999, Mr. Twomley informed the directors of his
discussions and meeting with Kellogg. The directors were supportive of continued
discussions with Kellogg.

         Following the July 16, 1999 meeting, Mr. Benoit contacted Mr. Twomley
and requested additional financial and other information regarding Worthington
in order to prepare a proposal for a business combination between Kellogg and
Worthington. Worthington provided this additional information to Kellogg between
July 21, 1999 and July 28, 1999. Mr. Benoit called Mr. Twomley on July 30, 1999
and said that he would like to meet again with representatives of Worthington
before proposing a purchase price for Worthington. Mr. Benoit also requested
additional financial information from Worthington.

         On August 6, 1999, Dale Twomley, William Kirkwood and Ronald McDermott
of Worthington met with Stephen Benoit, Robert Cell, John Cook and other
representatives of Kellogg at the Kellogg offices in Battle Creek to discuss the
Worthington business and the meat alternative category in general. Following
that meeting, the Worthington representatives met with Carlos M. Gutierrez, the
President and CEO of Kellogg, and discussed the strategic implications of a
business combination, the respective business and management philosophies and
goals of the two companies and the opportunities that a business combination
would afford the two companies.

         On Tuesday, August 10, 1999, Mr. Cell called Mr. Twomley to report that
the senior management of Kellogg was prepared to recommend the acquisition of
Worthington in a stock-for-stock transaction. Mr. Twomley responded that he
could not recommend the transaction to



                                       22
<PAGE>   26
the Worthington board at the proposed exchange ratio. Later that day, Mr. Cell
called Mr. Twomley and proposed a stock-for-stock acquisition at an increased
exchange ratio for each share of Worthington. Mr. Cell noted that the Kellogg
proposal was subject to review by the finance committee of Kellogg's board of
directors, which would meet by telephone conference on August 20, 1999, and to
further due diligence by Kellogg. Mr. Cell also requested that Worthington give
consideration to an all cash transaction.

         A telephonic special meeting of the Worthington board of directors was
held on August 11, 1999. Mr. Twomley provided a detailed review of the ongoing
discussions with Kellogg and outlined the preliminary structure of the proposed
business combination. Mr. Twomley and Worthington's financial and legal advisors
responded to questions and comments from the directors about the negotiation
process. Mr. Twomley advised the directors that if the board decided to move
forward with the negotiation of a definitive merger agreement with Kellogg, it
would be prudent to retain the services of an investment banking firm. After
discussion of the advisability of hiring an investment banking firm and the fee
arrangement, the board authorized the engagement of U.S. Bancorp Piper Jaffray
Inc. to serve as Worthington's financial advisor in connection with the proposed
merger with Kellogg.

         At the August 11, 1999 meeting, the Worthington directors discussed the
proposed purchase price and the advantages and disadvantages of receiving stock
versus cash in an acquisition. The directors reviewed with the financial
advisors and legal counsel the structural, tax, accounting and liquidity issues
relating to the proposed merger. Mr. Twomley discussed his position that the
Kellogg merger proposal, if completed, would benefit the shareholders, employees
and customers of the company. He noted the challenges and risks facing
Worthington as a small independent company, and the business and financial
opportunities that would be afforded to Worthington by a merger with a much
larger food company. Following a lengthy discussion, the board authorized
management to continue its discussions with Kellogg and to begin the negotiation
of a definitive merger agreement. The board also asked that Worthington's
management keep the Worthington board informed of material developments.

         On Friday, August 20, 1999, the finance committee of the board of
directors of Kellogg authorized Kellogg's management to continue its due
diligence review of Worthington and to begin negotiation of a definitive merger
agreement. Following that meeting, Mr. Benoit called Mr. Twomley and reported
that Kellogg wanted to begin an extensive financial, business, operational and
legal review of Worthington.

         On Tuesday, August 24, 1999, representatives of Kellogg and Worthington
met in Columbus to discuss Kellogg's due diligence plan and to agree on a
preliminary timetable for negotiating a definitive merger agreement. Kellogg
conducted its due diligence over a period of approximately four weeks beginning
on August 24, 1999, including management interviews, document review and legal
due diligence. During this period, there was a series of discussions between
Messrs. Benoit, Cell and Twomley concerning the potential business challenges of
a business combination, including integration of the Worthington management team
into the Kellogg organization and other business integration issues.

         The Worthington board of directors held a telephonic meeting on
Thursday, August 26, 1999. Mr. Twomley reviewed for the board the status of his
discussions with Kellogg. He advised the board that Kellogg was recommending an
all cash transaction. Following a lengthy discussion, the directors authorized
management to pursue an all cash transaction. Mr. Twomley reported the
Worthington board's action to Mr. Benoit on Friday, August 27, 1999.

         On Monday, August 30, 1999, Kellogg delivered to Worthington and its
investment bankers and attorneys an initial draft of the merger agreement.
Beginning on September 3, 1999 and continuing through the execution of the
merger agreement on September 30, 1999, Kellogg and Worthington, and their
respective legal advisors, negotiated the terms of the merger agreement.

         A regularly-scheduled meeting of the board of directors of Worthington
was held on Wednesday, September 8, 1999. At that meeting, Mr. Twomley updated
the directors on the status of discussions with Kellogg and reported on
Kellogg's due diligence review. Mr. Kirkwood reviewed with the directors the
financial information and financial forecasts that had been provided to Kellogg.
Legal counsel reviewed with the directors the terms and conditions of the
initial draft of the merger agreement and answered questions from the directors.

         On Monday, September 20, 1999, Mr. Benoit telephoned Mr. Twomley and
reported that, after reviewing the results of Kellogg's due diligence, Kellogg
had prepared a list of business issues for discussion with Worthington's
management. On Tuesday, September 21, 1999 and Wednesday, September 22, 1999,
numerous telephone conversations occurred between representatives of Worthington
and Kellogg concerning the issues raised by Kellogg.

         Mr. Twomley and Mr. Kirkwood met with Mr. Benoit and another Kellogg
representative on Thursday, September 23, 1999. During the meeting, Mr. Benoit
reported that Kellogg was prepared to proceed with the proposed merger at a
price of $22 per Worthington share in cash. Mr. Benoit noted that a $22 offer
price represented an 82.4% premium to the then current market price of $12.0625
per share and a 61.4% premium to the average stock price over the past six
months of $13.631 per share. He also pointed out that the $22 proposal valued
Worthington at a higher level than the average price paid for branded food
product companies over the past 10 years. Mr. Twomley responded that he did not
believe that the Worthington board of directors would authorize a transaction at
$22 per share. After further discussions, Mr. Twomley suggested a price of $24
per Worthington share. After reviewing the proposal with other Kellogg
representatives, Mr. Benoit said that Kellogg management would support a $24 per
share merger price, but that the price was subject to approval by the Kellogg
board of directors. Mr. Twomley responded that he would take the $24 proposal to
the Worthington board of directors at a previously-scheduled meeting the
following day.

         On Friday, September 24, 1999, the board of directors of Worthington
met to review the progress of the discussions with Kellogg. At that meeting, the
directors authorized management to complete its negotiation of a definitive
merger agreement. On the same day, the Kellogg's board of directors authorized
the Kellogg management to proceed with the completion of the negotiation of a
definitive merger agreement.

<PAGE>   28
         Copies of the draft merger agreement were sent to the Worthington
directors on Monday, September 27, 1999. In addition, on the same day, Mr.
Twomley and the Vice Presidents of Worthington met with Mr. Benoit and other
representatives of Kellogg to discuss employment and severance arrangements for
the Worthington executives following the merger.

         On Wednesday, September 29, 1999, the board of directors of Worthington
met to consider the definitive merger agreement. Worthington senior management,
financial advisors and legal counsel made various presentations concerning the
proposed transaction. In addition, U.S. Bancorp Piper Jaffray Inc. rendered its
oral opinion to the board of directors that, as of September 29, 1999, and based
upon and subject to certain assumptions, factors and limitations, the $24 per
share merger price was fair from a financial point of view to Worthington's
shareholders. The board of directors unanimously determined that it was in the
best interest of Worthington and its shareholders for Worthington to enter into
the merger agreement, determined that the terms of the merger were fair to, and
in the best interests of, the shareholders of Worthington, and authorized,
approved and adopted the proposed merger agreement and the execution and
delivery of the merger agreement. On September 30, 1999, U.S. Bancorp Piper
Jaffray Inc. delivered its written opinion as to the fairness, from a financial
point of view, to the Worthington shareholders of the $24 per share merger
price.

         The parties executed and delivered the merger agreement at the end of
the day on Thursday, September 30, 1999. On the morning of Friday, October 1,
1999, the parties issued a joint press release announcing that they had signed
the merger agreement.

WORTHINGTON'S REASONS FOR THE MERGER; RECOMMENDATION OF THE BOARD

         Worthington's board of directors has unanimously approved the merger
agreement and the merger and recommends adoption of the merger agreement and the
merger by the shareholders of Worthington. In reaching its determination, the
Worthington board of directors consulted with Worthington management, U.S.
Bancorp Piper Jaffray Inc., its financial advisor, and Vorys, Sater, Seymour and
Pease LLP, its legal counsel, and considered the following important factors
that supported the board's recommendation:

         (1) The per share cash consideration of $24 to be paid in the merger,
which represents a premium for the Worthington common shares of approximately
67% over the per share closing price on Thursday, September 30, 1999, the last
trading day prior to the date of public announcement of the merger agreement,
and approximately 84% over the closing price on August 30, 1999, a date one
month before the execution of the merger agreement;

         (2) The board's review and analysis of Worthington's business and
earnings prospects, anticipated future capital expenditure requirements, its
need for funds to achieve future plans, near-term and long-term product and
business risks, management succession issues, the competitive business
environment in which the company operates and business trends in the prepared
food industry;



                                       25
<PAGE>   29

         (3) The oral opinion of U.S. Bancorp Piper Jaffray Inc. that as of
September 29, 1999 (which opinion was set forth in writing and dated September
30, 1999) and based upon and subject to certain assumptions, factors and
limitations, the merger price of $24 per Worthington share was fair from a
financial point of view to the holders of Worthington common shares and the
related analyses prepared by U.S. Bancorp Piper Jaffray Inc.;

         (4) Historical market prices of Worthington's common shares;

         (5) A review of the prospects of continuing to operate as a stand-alone
company, including the anticipated short-term and long-term value to
shareholders of remaining an independent company and the timing and likelihood
of actually achieving greater value from this alternative and the risks
associated with remaining an independent company;

         (6) The merger should allow Worthington to benefit, over the long term,
from increased financial strength, the opportunity to benefit from costs savings
and other benefits of size and operating efficiencies and increased sales
through an expanded distribution channel and support system;

         (7) The terms of the merger agreement, including the right of the
Worthington board of directors to terminate the merger agreement prior to its
approval by shareholders in the exercise of its fiduciary duties in connection
with receipt by Worthington of a buy out proposal superior to that given by
Kellogg;

         (8) The ability of Worthington and Kellogg to complete the merger,
including the fact that the merger is not subject to a financing contingency on
the part of Kellogg;

         (9) The fact that the affirmative vote of a majority of the outstanding
common shares of Worthington is required to approve and adopt the merger
agreement; and

         (10) The social and economic effects of the merger on the employees,
customers, suppliers and others who deal with Worthington and on the communities
where they operate, including the intention of Kellogg to maintain operations in
Worthington and Zanesville, Ohio following the merger.

                  The discussion above describes the material factors considered
by the board of directors in its consideration of the merger. Because of the
variety of factors considered, the board did not find it practicable to, and did
not make specific assessments of, quantify or otherwise assign relative weights
to the specific factors considered in reaching its determination. The
determination was made after consideration of all of the factors together. In
addition, individual members of the Worthington board of directors may have
given different weights to different factors.

                  THE BOARD OF DIRECTORS OF WORTHINGTON UNANIMOUSLY RECOMMENDS
THAT SHAREHOLDERS OF WORTHINGTON VOTE FOR THE ADOPTION OF THE MERGER AGREEMENT
AND THE APPROVAL OF THE MERGER.

OPINION OF FINANCIAL ADVISOR TO WORTHINGTON

         Pursuant to an engagement letter dated August 20, 1999, Worthington
retained U.S. Bancorp Piper Jaffray Inc. to act as its exclusive financial
advisor and, if requested, to render to the board of directors of Worthington an
opinion as to the fairness, from a financial point of view, of the consideration
to be received by Worthington shareholders in the merger.

         At the meeting of the board of directors of Worthington held on
September 29, 1999, U.S. Bancorp Piper Jaffray Inc. rendered to the board of
directors its oral opinion that, as of that date and based on and subject to the
assumptions, factors and limitations presented in the opinion and described
below, the $24 per share in cash to be paid to the Worthington shareholders in
the merger was fair, from a financial point of view, to those shareholders. The

Inc.'s written opinion, and confirmation of opinion, are attached to this proxy

reference. YOU ARE URGED TO READ THE OPINION CAREFULLY IN ITS ENTIRETY.

         While U.S. Bancorp Piper Jaffray Inc. rendered its opinion and provided
certain financial analyses to the board of directors of Worthington, the opinion
of U.S. Bancorp Piper Jaffray Inc. to the board of directors of Worthington, as

                  of the proposed consideration to be received by Worthington
                  shareholders in the merger;

         -        U.S. Bancorp Piper Jaffray Inc.'s written opinion does not
                  address the value of a Worthington common share;

                  address Worthington's underlying business decision to
                  participate in the merger; and

         -        U.S. Bancorp Piper Jaffray Inc.'s written opinion does not
                  constitute a recommendation to any Worthington shareholder as
                  to how a shareholder should vote with respect to the merger or
                  any related matter.

         In arriving at its opinion, U.S. Bancorp Piper Jaffray Inc. reviewed:

                     Worthington operates;

              -      certain valuation and other financial information on
                     selected public companies deemed comparable to Worthington;
                     and

                     for Worthington, Kellogg and their respective common
                     stocks.

              discussions with:

              -      members of Worthington's management concerning the
                     financial condition, current operating results and business

                     into discussions regarding the merger.

              In delivering its opinion to the board of directors of
Worthington, U.S. Bancorp Piper Jaffray Inc. prepared and delivered to the board
of directors written materials containing various analyses and other information
material to the opinion. The following is a summary of those analyses. The
summary includes information presented in tabular format. In order to understand
fully the financial analyses used by U.S. Bancorp Piper Jaffray Inc., these
tables must be read together with the text of each analysis summary. The tables
alone do not constitute a complete summary of the analyses. The order in which
the analyses are presented below should not be taken as any indication of the
relative weight given to the analyses by U.S. Bancorp Piper Jaffray Inc. in the
rendering of its opinion.

              Proposed Consideration. Based on the proposed $24 per share merger
price to be paid for each of Worthington common share, U.S. Bancorp Piper
Jaffray Inc. calculated the implied aggregate equity value of Worthington to be
approximately $308.6 million, consisting of approximately $297.3 million in
common share consideration and approximately $11.3 million in consideration
payable to holders of options to purchase Worthington's common shares. Based on
this implied aggregate equity value and the approximately $37.4 million of debt
and the approximately $2.6 million of cash on Worthington's balance sheet as of
August 27, 1999, U.S. Bancorp Piper Jaffray Inc. then calculated the implied
aggregate "enterprise value" or "company value" (equity value, plus debt, less
cash) to be approximately $343.4 million. Based on these implied aggregate
equity and enterprise values for Worthington, on Worthington's revenue, EBITDA
(earnings before interest, taxes, depreciation and amortization), operating
income and



                                       28

net income for the latest twelve months ("LTM") as of August 27, 1999 and on
management's estimates for Worthington's net income for fiscal years 1999 and
2000, U.S. Bancorp Piper Jaffray Inc. also calculated the following valuation
multiples for the proposed transaction:

                                                                   Implied

              Comparable Company Analysis. U.S. Bancorp Piper Jaffray Inc.
compared financial information and valuation ratios relating to Worthington to
corresponding data and ratios from the following four publicly-traded companies
deemed comparable to Worthington: Celestial Seasonings, Inc.; Gardenburger,
Inc.; Hain Food Group Inc.; and Horizon Organic Holding Corporation. This group
was selected from food manufacturers and distributors with a focus on natural,
organic, vegetarian or other healthy food products with a market capitalization
greater than $50 million.

              Based on the comparable companies' share prices and shares
outstanding as of September 28, 1999 and research analysts' consensus earnings
per share estimates for these companies, U.S. Bancorp Piper Jaffray Inc.
calculated valuation multiples for the comparable companies equal to the
quotient of their respective valuation data, such as company value and equity
value, and their associated operating data, such as revenue and operating
income. U.S. Bancorp Piper Jaffray Inc. then compared the means and medians of
these multiples to the Worthington valuation multiples derived as described
above, and also calculated implied per share values for Worthington's common
shares derived from these comparable companies' valuation multiples, the
corresponding operating data for Worthington and fully diluted shares
outstanding assuming a $24 share price.

              Comparable Transaction Analysis. U.S. Bancorp Piper Jaffray Inc.
reviewed the terms of certain recent merger and acquisition transactions
reported in SEC filings, public company disclosures, press releases, industry
and popular press reports, data bases and other sources that satisfied the
following criteria:

              -   transactions in which the target company operates in the food
                  and kindred products industry;

              -   transactions with a value of greater than $10 million;

              -   transactions not in the nature of repurchases or spinoffs; and

              -   transactions in which the acquiring company purchased at least
                  50% of the target company.

              This search yielded 45 "food industry" comparable acquisitions
deemed to have sufficient data available for analysis. In addition, a group of
six "natural foods" comparable acquisitions was chosen, involving food producers
and distributors that focus on natural, organic, vegetarian or other healthy
food products.

              U.S. Bancorp Piper Jaffray Inc. calculated valuation multiples for
the acquired companies in the comparable transactions equal to the quotient of
their respective valuation data, such as company value and equity value, and
their associated operating data, such as revenue, operating income and EBITDA.
U.S. Bancorp Piper Jaffray Inc. then compared the means and medians of these
multiples to the Worthington valuation multiples derived as described above, and
also calculated implied per share values for Worthington's common shares derived
from these comparable transaction valuation multiples, the corresponding
operating data for Worthington and fully diluted shares outstanding assuming a
$24 share price.

              Premiums Paid Analysis. U.S. Bancorp Piper Jaffray Inc. analyzed
the implied premium paid or proposed to be paid in selected transactions
relative to public market pre-announcement trading prices for the following two
groups:

              -      food industry acquisitions since January 1, 1993 involving
                     more than $10 million in equity value; and

              -      non-industry specific transactions since January 1, 1997
                     involving between $100 million and $500 million in equity
                     value.

              U.S. Bancorp Piper Jaffray Inc. calculated an implied value per
share for Worthington's common shares based on the mean and median premium data
associated with the applicable transaction groups and upon the Worthington
common share closing price on September 28, 1999, of $12.31, as detailed below:

       Discounted Cash Flow Analysis. U.S. Bancorp Piper Jaffray Inc. performed
a discounted cash flow analysis on Worthington in which it calculated the sum of
the present values of:

              -      the projected cash flows of Worthington using assumptions
                     prepared by Worthington management; and

              -      the estimated terminal (or perpetual) value of Worthington
                     for the period of time from the end of the projections
                     provided by Worthington's management forward.

         In making these calculations, U.S. Bancorp Piper Jaffray Inc. applied a
range of terminal value EBITDA multiples of 8.0x to 12.0x and a range of
discount rates of 13.0% to 17.0%. This analysis yielded the following implied
per share equity values for Worthington's common shares:

         In reaching its conclusion as to the fairness, from a financial point
of view, of the consideration to be received by Worthington's shareholders in
the merger, U.S. Bancorp Piper Jaffray Inc. did not rely on any single analysis
or factor described above, assign relative weights



                                       32
<PAGE>   36

to the analyses or factors considered by it, or make any conclusion as to how
the results of any given analysis, taken alone, supported its opinion. The
preparation of a fairness opinion is a complex process and not necessarily
susceptible to partial analysis or summary description. U.S. Bancorp Piper
Jaffray Inc. believes that its analyses must be considered as a whole and that
the selection of portions of its analyses and of the factors considered by it,
without considering all of the factors and analyses, would create a misleading
view of the processes underlying the opinion.

         The analyses of U.S. Bancorp Piper Jaffray Inc. are not necessarily
indicative of actual values or future results, which may be significantly more
or less favorable than suggested by the analyses. Analyses relating to the value
of companies do not purport to be appraisals or valuations or necessarily
reflect the prices at which businesses or securities may actually be sold. No
company or transaction used in any analysis for purposes of comparison is
identical to Worthington or the merger. In addition, in performing its analyses,
U.S. Bancorp Piper Jaffray Inc. made numerous assumptions with respect to
industry performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of the
parties to the merger and U.S. Bancorp Piper Jaffray Inc. Accordingly, an
analysis of the results of the comparisons is not mathematical; rather, it
involves complex considerations and judgments about differences in the companies
to which Worthington was compared and other factors that could affect the public
trading value of Worthington's common shares. Because such analyses are
inherently subject to uncertainty, being based upon numerous factors and events
beyond the control of the parties to the merger and U.S. Bancorp Piper Jaffray
Inc., neither the parties nor U.S. Bancorp Piper Jaffray Inc. assume
responsibility if future results are materially different from those forecast.

         For purposes of its opinion, U.S. Bancorp Piper Jaffray Inc. relied
upon and assumed the accuracy, completeness and fairness of the financial
statements and other information provided to it by Worthington or otherwise made
available to U.S. Bancorp Piper Jaffray Inc. and did not assume responsibility
for the independent verification of that information. With respect to the
financial statement data and other internal financial information (including the
projected financial planning data) provided to U.S. Bancorp Piper Jaffray Inc.
in connection with its review of the financial aspects of the merger, U.S.
Bancorp Piper Jaffray Inc. relied upon the assurances of the management of
Worthington that the information was prepared on a reasonable basis, and, with
respect to the financial planning data, reflected the best currently available
estimates, and that management was not aware of any information or facts that
would make the information provided to U.S. Bancorp Piper Jaffray Inc.
incomplete or misleading.

         In arriving at its opinion, U.S. Bancorp Piper Jaffray Inc. was not
requested to perform, did not perform, and was not furnished with any appraisals
or valuations of any specific assets or liabilities of Worthington. U.S. Bancorp
Piper Jaffray Inc. was not requested to opine as to, and its opinion did not
address, the basic business decision to proceed with or effect the merger or to
compare the merger to, or to consider, alternative transactions that may have
been available to Worthington. U.S. Bancorp Piper Jaffray Inc. analyzed
Worthington as a going concern and accordingly expressed no opinion as to its
liquidation value. The opinion is based on information available to U.S. Bancorp
Piper Jaffray Inc. and the facts and circumstances as they existed and were
subject to evaluation on the opinion date. Events occurring after that date
could materially affect the assumptions used in preparing the opinion. U.S.
Bancorp Piper Jaffray Inc.

has not undertaken and is not obligated to affirm or revise its opinion or
otherwise comment on any events occurring after the date it was given, unless
any "bring-down" fairness opinions are requested by Worthington.

         U.S. Bancorp Piper Jaffray Inc., as a customary part of its investment
banking business, evaluates businesses and their securities in connection with
mergers and acquisitions, underwritings and secondary distributions of
securities, private placements and valuations for estate, corporate and other
purposes. The board of directors of Worthington selected U.S. Bancorp Piper
Jaffray Inc. because of its expertise, reputation and familiarity with
Worthington and the food manufacturing and distributing industry in general.
U.S. Bancorp Piper Jaffray Inc. maintains a market in the common shares of
Worthington. In the ordinary course of business, U.S. Bancorp Piper Jaffray Inc.
and its affiliates may actively trade securities of Worthington and Kellogg for
their own accounts or the accounts of their customers and, accordingly, may at
any time hold a long or short position in those securities.

         Under the terms of the engagement letter dated August 20, 1999,
Worthington has agreed to pay U.S. Bancorp Piper Jaffray Inc. the following:

         -  $300,000 upon the delivery of U.S. Bancorp Piper Jaffray Inc.'s
            initial fairness opinion (which has already been paid by
            Worthington);

         -  $25,000 upon the delivery of any bring-down fairness opinions; and

         -  a fee equal to $1,000,000 upon the closing of the merger, less any
            amounts paid upon delivery of initial or bring-down fairness
            opinions as described above.

         The engagement letter also provides that Worthington will reimburse
U.S. Bancorp Piper Jaffray Inc. for its reasonable out-of-pocket expenses,
including fees and disbursements of counsel, and will indemnify U.S. Bancorp
Piper Jaffray Inc. and related parties from and against certain liabilities,
including liabilities under the federal securities laws, arising out of or in
connection with the engagement of U.S. Bancorp Piper Jaffray Inc..

INTERESTS OF CERTAIN PERSONS IN THE MERGER

         In considering the recommendation of Worthington's board of directors
that the shareholders vote in favor of the adoption of the merger agreement,
shareholders should be aware that Worthington's executive officers and directors
will receive payments and other benefits as a result of the merger which result
in their having interests in the merger that are different from, or in addition
to, the interests of other shareholders. The board was aware of these interests
and considered them, among other things, in approving the merger agreement.

         Agreements with Executive Officers and Other Key Employees. Worthington
has in place change in control severance agreements with each of its seven
executive officers and two of its other key employees. These severance
agreements were entered into on August 25, 1995 (except for the severance
agreements with individuals who began their employment or were promoted to key
positions after such date and who received severance agreements when they began
their employment with Worthington or were promoted). The severance agreements
provide for



                                       34
<PAGE>   38

severance and change in control benefits if qualifying terminations of
employment occur after a change in control of Worthington. The merger will
constitute a change in control under these severance agreements. On September
30, 1999, Kellogg entered into written agreements (the "Kellogg Agreements")
with Worthington's seven executives officers and the two other key employees who
are parties to severance agreements with Worthington which will become effective
only upon the completion of the merger and which provide, among other things,
for termination of the existing severance agreements and the payment to these
individuals following the merger of amounts that approximate the payments they
would have received under their severance agreements if they had a qualifying
termination of employment following the merger. The following is a summary of
the terms and conditions of the Kellogg Agreements with Worthington's seven
executive officers:

         Agreement with Dale E. Twomley. Dale E. Twomley, Chairman, President
and Chief Executive Officer, will receive the following payments and benefits
under the Kellogg Agreement to which he is a party:

      terminate Mr. Twomley's severance agreement with Worthington. This amount
      will be paid on a date of Mr. Twomley's choice in 2000.

   -  Kellogg will employ Mr. Twomley from the date on which the merger is
      effective through December 31, 2000 at an annual salary of $260,040 per
      year plus health care, pension and other benefits comparable to those
      provided to Mr. Twomley by Worthington prior to the merger.

   -  If Mr. Twomley remains actively employed by Kellogg through December 31,
      2000 and the Natural and Functional Food Division of Kellogg meets or
      exceeds its targeted objectives for 2000, which are based upon prescribed
      net sales and operating profit figures, Mr. Twomley will receive a bonus
      equal to two year's base pay, less applicable taxes and withholdings. If
      Mr. Twomley is terminated by Kellogg (other than for willful misconduct)
      prior to December 31, 2000, he will still be entitled to receive this
      bonus amount if the targeted objectives for 2000 are met or exceeded.

   -  Subject to his compliance therewith, Mr. Twomley will receive $200,000
      (less applicable taxes and withholdings) under a two-year noncompetition
      agreement with Kellogg. This amount is payable over two years.

   -  Upon termination of employment, Mr. Twomley will be entitled to
      outplacement services.

         Agreement with William T. Kirkwood. William T. Kirkwood, Executive Vice
President and Chief Financial Officer, will receive the following payments and
benefits under the Kellogg Agreement to which he is a party:

                  Agreement with B. Eugene Fluck. B. Eugene Fluck, Vice

the Kellogg Agreement to which he is a party:

   -  Payment of $200,953 (less applicable taxes and withholdings) to terminate
      Mr. Fluck's severance agreement with Worthington. This amount will be paid
      on a date of Mr. Fluck's choice in 2000.

   -  Kellogg will employ Mr. Fluck "at will" for an indefinite period at a
      starting annual salary of $126,600. If he is actively employed and
      performing satisfactorily until 18 months after the date on which the
      merger is effective, Mr. Fluck will receive a one-time bonus of 40% of his
      base salary. If Mr. Fluck is terminated by Kellogg (other than for willful
      misconduct) before the end of the 18-month period, he will still be

         will still be entitled to receive this bonus. Mr. McDermott will also

         Cash-Out of Outstanding Stock Options. Worthington has previously
granted stock options to its employees, including its executive officers, and
its non-employee directors under its stock option plans. Under the merger
agreement, immediately prior to the completion of the merger, each option holder
will be paid an amount in consideration of the cancellation of his outstanding
stock options (whether or not then exercisable) equal to the product of the
excess, if any, of $24 over the exercise price per share of the options, and the
number of common shares subject to the options. Each payment will be made net of
applicable withholding taxes. Prior to the effective time of the merger,
Worthington has agreed to use its reasonable best efforts and otherwise take all
actions reasonably necessary to implement the cash-out of the stock options in
accordance with the merger agreement. It is estimated that a total of
$10,967,000 will be paid to employees (including executive officers) and
directors of Worthington in connection with the cash-out of their outstanding
stock options (prior to reduction for any amounts required to be withheld for
taxes).

         The following table shows, for each of the executive officers and
directors of Worthington, the aggregate amount that will be paid to that
individual immediately prior to the effective time of the merger in cancellation
of stock options (whether or not exercisable) held by him on the date of this
proxy statement. It is anticipated that no additional stock options will be
granted to any director, executive officer or other employee of Worthington
prior to the effective time of the merger.

</TABLE>

         Bonus Arrangements for 1999. The merger agreement provides that prior
to the merger Worthington will make bonus payments to the Vice Presidents, the
Executive Vice President and the President of Worthington in amounts to be
determined as follows. These bonus payments are the same bonus payments to which
the Vice Presidents, the Executive Vice President and the President would be
entitled if the merger were not occurring. If the merger is completed in 1999,
and as of the merger date Worthington has achieved its sales projections through
the last day of the month immediately preceding that in which the merger date
occurs, then Worthington will pay to each of the Vice Presidents a payment equal
to 20% of his Base Salary Amount, to the Executive Vice President a payment
equal to 30% of his Base Salary Amount and to the President a payment equal to
40% of his Base Salary Amount. If these sales projections are not met, then
Worthington will pay to each of the Vice Presidents, the Executive Vice
President and the President an amount equal to 10% of his Base Salary Amount.
(The "Base Salary Amount" for an individual is the amount of base salary paid to
such individual from January 1, 1999 through the earlier of the effective time
of the merger or December 31, 1999.) If the merger is completed in 2000,
Worthington will make bonus payments to the Vice Presidents, the Executive Vice
President and the President based on whether or not Worthington's sales
projections for the year ended December 31, 1999 were achieved. Worthington's
sales projections on which the bonus payments will be based have been delivered
to Kellogg. This sales-based bonus plan will replace Worthington's regular
incentive program for its officers for 1999. If Worthington achieves its 1999
sales projections, the maximum bonuses payable to the Vice Presidents, the
Executive Vice President and the President of Worthington will be as follows:

         Indemnification and D & O Insurance. After the merger is completed,
Kellogg will cause Worthington to indemnify, advance expenses to and hold
harmless the present and former officers and directors of Worthington and its
subsidiary in respect of acts or omissions occurring prior to the effective time
of the merger to the extent provided under Worthington's or its subsidiary's
charter documents in effect on September 30, 1999.

         For a period of six years after the effective time of the merger and
for so long after that period as any claim for insurance coverage previously
asserted has not been fully resolved, Kellogg or Worthington will maintain in
effect the existing policy of directors' and officers' liability insurance
maintained by Worthington on September 30, 1999 (or a policy providing at least
the same coverage and containing terms that are no less advantageous to the
insureds as provided by Worthington's existing policy) with respect to acts or
omissions of existing or former officers and directors of Worthington and its
subsidiary occurring prior to the effective time of the merger provided that
neither Kellogg nor Worthington will be required to pay an annual premium for
this insurance coverage in excess of $150,000 and provided further that, if such
insurance cannot be so maintained or obtained at such cost, Kellogg or
Worthington will maintain or obtain as much of such insurance as can be so
maintained or obtained at a cost of $150,000.

FEDERAL INCOME TAX CONSEQUENCES

         The following is a general summary of the federal income tax
consequences of the merger to holders of common shares. This discussion is based
on the Internal Revenue Code of 1986, as amended, existing and proposed
regulations thereunder, Internal Revenue Service rulings and pronouncements,
reports of congressional committees, judicial decisions and current
administrative rulings and practice, all as in effect on the date of this proxy
statement. Any change to the foregoing sources could be retroactive and,
accordingly, could modify the tax consequences discussed in this section.
Worthington has not requested a ruling from the IRS with respect to the matters
discussed in this section and there is no assurance that the IRS will agree with
the conclusions set forth in this discussion. In addition, Worthington has not
requested or received a tax opinion with respect to the federal income tax
consequences of the merger.

         This discussion does not address all of the federal income tax
consequences that may be relevant to particular shareholders in light of their
personal circumstances or to certain types of shareholders (such as dealers in
securities, corporations, insurance companies, foreign



                                       40
<PAGE>   44

individuals and entities, financial institutions and tax-exempt entities) who
may be subject to special treatment under the federal income tax laws. It also
does not address the federal income tax consequences to shareholders who
acquired their common shares through the exercise of employee stock options or
otherwise as compensation. Furthermore, this discussion does not address any tax
consequences under state, local or foreign laws. This summary assumes that
common shares are held as "capital assets" within the meaning of Section 1221 of
the Internal Revenue Code. Under Section 1221, capital assets are those assets
that are generally held for investment.

         For federal income tax purposes, an individual who exchanges his or her
common shares for cash pursuant to the merger or who receives cash in exchange
for common shares pursuant to the exercise of dissenters' rights will be treated
as having sold his or her common shares for cash in a taxable transaction. The
shareholder will recognize gain or loss on the exchange in an amount equal to
the difference between the cash received and the holder's adjusted tax basis in
the common shares. The gain or loss will be a capital gain or loss if the holder
of the common shares held them as a capital asset at the effective time of the
merger, and may qualify as long-term capital gain or loss if the holder held the
common shares for more than 12 months at the effective time of the merger. For
certain non-corporate holders of common shares (including individuals), any
long-term capital gain will be taxed at a maximum federal income tax rate of
20%. Short-term capital gain of these individuals will be taxed as ordinary
income. Ordinary income of individuals is currently taxed at a maximum federal
income tax rate of 39.6%. For corporate holders of common shares, long-term
capital gain will continue to be subject to ordinary income tax rates applicable
to corporations.

         Holders of common shares or other payees generally will be required to
provide the merger payment agent with their correct taxpayer identification
numbers (certified under penalties of perjury) on the Substitute Forms W-9
included as part of the letters of transmittal sent to shareholders pursuant to
the merger. An individual's taxpayer identification number is his or her social
security number. A holder of common shares or other payee who does not provide
the merger payment agent with a correct taxpayer identification number may be
subject to a $50 fine imposed by the IRS. Furthermore, payments made to a holder
of common shares or other payee may be subject to backup withholding if: (i) a
holder of common shares or other payee fails to furnish a correct taxpayer
identification number, (ii) a holder of common shares or other payee furnishes
an incorrect taxpayer identification number, (iii) Worthington, Kellogg or the
merger payment agent is notified by the IRS that the holder of common shares or
other payee failed to report interest or (iv) under certain circumstances, a
holder of common shares fails to provide a certified statement, signed under
penalty of perjury, that the taxpayer identification number provided is the
correct number and that the holder of the common shares is not subject to backup
withholding.

         If backup withholding applies, the merger payment agent will withhold
31% of any payment made to a holder of common shares or other payee. Backup
withholding is not an additional tax but is credited against the federal income
tax liability of the taxpayer subject to the withholding. If backup withholding
results in an overpayment of a taxpayer's federal income taxes, that taxpayer
may obtain a refund from the IRS.



                                       41
<PAGE>   45

         Generally, a holder of common shares or other payee may avoid backup
withholding by completing the Substitute Form W-9 included as part of the letter
of transmittal and certifying that the taxpayer identification number included
therein is correct and that the holder of common shares or other payee is not
subject to backup withholding. Certain types of taxpayers (including
corporations and certain foreign individuals) are not subject to these reporting
or withholding requirements.

         Holders of common shares are urged to consult their tax advisors as to
the particular tax consequences to them of participating in the merger,
including the applicability of any state, local or foreign tax laws, changes in
applicable tax laws and any pending or proposed legislation.

ACCOUNTING TREATMENT

         The merger will be accounted for as a purchase for financial accounting
purposes under generally accepted accounting principles.

EXISTING RELATIONSHIPS WITH KELLOGG

         Except in connection with the merger agreement and the transactions
contemplated thereby, Worthington has never conducted business with nor has it
had any business relationship with Kellogg prior to the transactions described
in the merger agreement. As of the date of this proxy statement, neither Kellogg
nor any of its affiliates owns any common shares.

RIGHTS OF DISSENTING SHAREHOLDERS

         The following is a description of the steps you must take to perfect
dissenters' rights with respect to the merger. The description is not intended
to be complete and is qualified in its entirety by reference to Section 1701.85
of the Ohio Revised Code, a copy of which is included as Appendix C to this
proxy statement. We recommend that you consult with your own counsel if you have
questions with respect to your rights under the statute.

         "Dissenters' rights" is your right to dissent from the merger and to
have the "fair cash value" of your common shares determined by a court and paid
in cash. The "fair cash value" of a common share is the amount that a willing
seller who is under no compulsion to sell would be willing to accept and that a
willing buyer who is under no compulsion to purchase would be willing to pay.
Fair cash value is determined as of the day prior to the day on which the vote
of the shareholders adopting the merger agreement is taken. When determining
fair cash value, any appreciation or depreciation in market value resulting from
the proposed merger is excluded. In no event can the fair cash value of a common
share exceed the amount specified in the demand of the particular shareholder
discussed in numbered paragraph 3 below.

         To perfect dissenters' rights, you must satisfy each of the following
conditions:

         1.       You Must be a Shareholder of Worthington on the Record Date.
                  To be entitled to dissenters' rights, you must be the record
                  holder of the dissenting shares on ____________, 1999. If you
                  have a beneficial interest in common shares held of record in
                  the name of any other person for which you desire to perfect
                  dissenters'


                                       42
<PAGE>   46

                  rights, you must cause the shareholder of record timely and
                  properly to act to perfect such rights.

         2.       You Must Not Vote in Favor of Adoption of the Merger
                  Agreement. Only a shareholder whose common shares are not
                  voted in favor of adoption of the merger agreement is
                  entitled, if the merger is completed, to be paid the fair cash
                  value of the common shares held of record by the shareholder
                  on ____________, 1999. A vote for adoption of the merger
                  agreement constitutes a waiver of dissenters' rights.

         3.       You Must Serve a Written Demand. On or before the tenth day
                  following the shareholders' vote adopting the merger
                  agreement, a shareholder who wishes to dissent must serve a
                  written demand on Worthington for the fair cash value of the
                  dissenting shares. The written demand must specify the
                  shareholder's name and address, the number of common shares as
                  to which relief is sought and the amount claimed by the
                  shareholder as the fair cash value of the common shares for
                  which the shareholder is exercising dissenters' rights.

         4.       You Must Deliver your Certificates for Legending, if Requested
                  by Worthington. If requested by Worthington, you must submit
                  your certificates for dissenting shares to Worthington within
                  fifteen days after Worthington sends its request. Worthington
                  will then endorse the certificates with a legend that demand
                  for fair cash value has been made.

         5.       You Must File a Petition in Court, if You and Worthington
                  Cannot Agree on the Fair Cash Value of your Dissenting Shares.
                  If Worthington and any dissenting shareholder cannot agree on
                  the fair cash value of the dissenting shares, either
                  Worthington or the shareholder must, within three months after
                  service of the written demand by the shareholder, file or join
                  in a petition in the Court of Common Pleas of Franklin County,
                  Ohio, for a determination of the fair cash value of the
                  dissenting shares.

         If you dissent from the merger, your right to be paid the fair cash
value of your common shares will terminate:

         -        if, for any reason, the merger is not completed;

         -        if you fail to serve a timely and appropriate written demand
                  upon Worthington;

         -        if you do not, upon request of Worthington, make timely and
                  appropriate surrender of the certificates evidencing your
                  dissenting shares for endorsement of a legend that demand for
                  the fair cash value of such common shares has been made;

         -        if your demand is withdrawn with the consent of the directors
                  of Worthington;

                                       43
<PAGE>   47

         -        if Worthington and you have not agreed upon the fair cash
                  value of your dissenting shares and you have not timely filed
                  or joined in an appropriate petition in the Court of Common
                  Pleas of Franklin County, Ohio; or

         -        if you otherwise fail to comply with the requirements of
                  Section 1701.85 of the Ohio Revised Code.

                          TERMS OF THE MERGER AGREEMENT

         The following description of the merger agreement does not purport to
be complete and is qualified in its entirety by reference to the merger
agreement, a copy of which is attached as Appendix A to this proxy statement and
is incorporated in this proxy statement by reference.

EFFECTIVE TIME OF THE MERGER

         The merger will become effective upon the filing of the appropriate
certificate of merger with the Secretary of State of the State of Ohio. Assuming
all conditions to the merger contained in the merger agreement are satisfied or,
to the extent susceptible to waiver, waived prior thereto, it is anticipated
that the effective time of the merger will occur on the eleventh calendar day
following the satisfaction or waiver of these conditions. See "--Conditions to
the Merger."

MANNER AND BASIS OF CONVERTING COMMON SHARES

         At the effective time of the merger, by virtue of the merger and
without any action on the part of any holder of any capital stock of
Worthington, Kellogg or WF Acquisition Inc., each issued and outstanding common
share of Worthington (other than treasury shares, common shares held by Kellogg,
WF Acquisition Inc. or any other wholly-owned subsidiary of Kellogg, and common
shares held by shareholders of Worthington who have properly exercised
dissenters' rights under Ohio law) will be automatically converted into the
right to receive $24 in cash. All common shares of Worthington will no longer be
outstanding and will automatically be canceled and retired and will cease to
exist. Each holder of a common share certificate will cease to have any rights
with respect thereto, except the right to receive the $24 per share merger
price, upon the surrender of the common share certificate, without interest,
subject to any applicable withholding tax. All common shares that Worthington
owns as treasury shares and any common shares owned by Kellogg, WF Acquisition
Inc. or any other wholly-owned subsidiary of Kellogg will be canceled and
retired. Each issued and outstanding common share of WF Acquisition Inc. will be
automatically converted into and become one fully paid and nonassessable common
share of the surviving corporation in the merger. Each certificate representing
outstanding WF Acquisition Inc. common shares will at the effective time of the
merger represent an equal number of common shares of Worthington as the
surviving corporation. Holders of common shares of Worthington have the right
under Section 1701.85 of the Ohio Revised Code to dissent from the merger. See
"The Merger--Rights of Dissenting Shareholders."

         Prior to the effective date of the merger, Kellogg will designate a
bank or trust company to serve as the payment agent for the merger. At the
closing of the merger, Kellogg will deposit with the payment agent, in a
separate fund established for the benefit of the holders of common



                                       44
<PAGE>   48

shares, for payment through the payment agent, a sufficient amount of cash to
pay to the holders of common shares the aggregate merger price.

         As soon as reasonably practicable after the effective time of the
merger, Worthington, as the surviving corporation in the merger, will instruct
the payment agent to mail to each holder of record of a common share certificate
immediately prior to the effective time of the merger (other than dissenting
shareholders) (i) a form of letter of transmittal (which will specify that
delivery will be effected, and risk of loss and title to the common share
certificates will pass, only upon proper delivery of the common share
certificates to the payment agent) and (ii) instructions for use in effecting
the surrender of the common share certificates in exchange for payment of the
merger price. Upon surrender of a common share certificate for cancellation to
the payment agent, together with a duly executed letter of transmittal and the
other documents the payment agent requires, the holder of such share certificate
will be entitled to receive the merger price of $24 per share, and the
surrendered share certificate will be canceled. No interest will be paid or
accrued on the merger price payable upon the surrender of any share certificate.
In order for someone other than the registered holder of the surrendered common
share certificate to receive the payment, the surrendered share certificate must
be properly endorsed or otherwise be in proper form for transfer. In addition,
the person requesting payment must either pay any transfer or other taxes
required by reason of the payment being made to someone other than the
registered holder of the surrendered common share certificate or establish to
the satisfaction of the surviving corporation that such tax has been paid or is
not applicable. From the effective time of the merger until surrendered as
described in this paragraph, each common share certificate (other than
certificates held by dissenting shareholders) will represent only the right to
receive upon surrender the $24 per share merger price.

         Following the effective time of the merger, unless otherwise required
by law, no transfer of any common shares will be made. If, after the effective
time of the merger, any common share certificates (other than certificates held
by dissenting shareholders) are presented to the payment agent for transfer,
they will be canceled and exchanged for the $24 per share merger price.

         Kellogg is entitled to withhold from the merger price amounts required
to be withheld under the Internal Revenue Code or any provision of state, local
or foreign tax law. To the extent withheld, the withheld amounts will be treated
for all purposes as having been paid to the holder of common shares in respect
of which the deduction and withholding was made by Kellogg.

         All funds that the payment agent holds for payment that remain
undistributed to the holders of common shares one year after the effective time
of the merger will be returned to Worthington as the surviving corporation in
the merger. Any holders of unsurrendered common share certificates may then look
only to Worthington, as the surviving corporation, for payment of the merger
price to which they are entitled, subject to applicable law. Kellogg, WF
Acquisition Inc. and Worthington will not be liable to any person for cash
representing the merger price delivered to a public official under any
applicable abandoned property, escheat or similar law.



                                       45
<PAGE>   49

STOCK OPTIONS

         Immediately prior to the completion of the merger, each outstanding
option to purchase common shares granted under Worthington's 1985 Stock Option
Plan, Amended and Restated 1995 Stock Option Plan and 1993 Stock Option Plan for
Non-Employee Directors, whether or not then exercisable, will be canceled and,
in consideration of such cancellation, Worthington will pay to the option holder
an amount in respect of his or her outstanding options (whether or not then
exercisable) equal to the product of the excess, if any, of $24 per share over
the exercise price of the option and the number of common shares subject to the
option. This payment will be made net of applicable withholding taxes.
Worthington has agreed in the merger agreement to use its reasonable best
efforts and otherwise take all actions reasonably necessary to implement the
cash-out of the stock options as provided in the merger agreement. See "The
Merger--Interests of Certain Persons in the Merger."

OTHER EMPLOYEE BENEFIT PLANS AND RELATED MATTERS

         As of the effective time of the merger, Worthington will amend its Tax
Savings and Profit Sharing Plan to eliminate any investment fund comprised of
common shares, prohibit any additional contributions in the form of common
shares and make all participant accounts fully vested and nonforfeitable. In
addition, as of the effective time of the merger, Worthington will amend its
Employee Stock Ownership Plan (the "ESOP") to provide that benefits will be
distributed solely in cash. The merger agreement requires that Kellogg cause the
surviving corporation of the merger to terminate the ESOP within 30 days after
the effective time of the merger and, as soon as administratively practicable
after that date, to take all action needed to liquidate the ESOP by distributing
its assets as provided by the terms of the ESOP.

         Kellogg has agreed that, except for employees covered by any collective
bargaining agreement, Kellogg will cause Worthington, as the surviving
corporation in the merger, to cause all employee benefit plans (other than
share-based plans) to remain in effect until the second anniversary of the
effective time of the merger or cause Worthington to maintain until such date
benefit plans which are substantially comparable, in total, to the benefit plans
maintained on the date of the merger agreement.

         The merger agreement permits Worthington prior to the effective time of
the merger to make a contribution to its Tax Savings and Profit Sharing Plan in
an amount equal to 3% of each participant's base salary paid from January 1,
1999 through the merger date. Kellogg has agreed in the merger agreement to
provide, or to cause Worthington after the merger to provide, to each salaried
employee who is terminated by Worthington (other than for cause) within six
months of the merger outplacement services.

         The merger agreement also provides that Worthington will make bonus
payments to the Vice Presidents, the Executive Vice President and the President
of Worthington based upon whether or not Worthington achieves its sales
projections for 1999. See "Interests of Certain Persons in the Merger--Bonus
Arrangements for 1999."

                  complete the merger and the other matters contemplated by the
                  merger agreement have been obtained, unless the failure to
                  obtain such approval or take such action could be reasonably
                  expected to not have a material adverse effect on Kellogg and
                  its subsidiaries or the surviving corporation and its
                  subsidiaries, in each case taken as a whole, or on the ability
                  of Kellogg and Worthington to consummate the transactions
                  contemplated by the merger agreement.

waiver, where permissible, of the following conditions:

         -        each representation and warranty made by Worthington in the
                  merger agreement that is qualified by materiality is true and

                  of representations and warranties made as of a specified date

                  certificate to such effect;

         -        Worthington has performed and complied with, in all material
                  respects, each agreement, covenant and obligation required by
                  the merger agreement to be performed or complied with by it at
                  or prior to the closing of the merger, and Worthington has
                  delivered to Kellogg a certificate to such effect;

<PAGE>   51

         -        on or prior to the closing date of the merger, the rights
                  issued under Worthington's Rights Agreement have not become
                  exercisable or transferable apart from the associated common
                  shares, no "Shares Acquisition Date" or "Distribution Date"
                  (each as defined in the Rights Agreement) has occurred and the
                  rights have been redeemed in accordance with the terms of the
                  Rights Agreement;

         -        the number of Worthington common shares held by persons who
                  have exercised dissenters' rights under Ohio law does not
                  exceed 10% of the total number of outstanding common shares;
                  and

         -        all proceedings to be taken on the part of Worthington in
                  connection with the closing of the merger transactions and all
                  documents incident thereto are reasonably satisfactory to
                  Kellogg, and Kellogg has received copies of all such documents
                  as Kellogg may reasonably request.

         Worthington. The obligation of Worthington to consummate the merger is
subject to the following conditions:

         -        each representation and warranty made by Kellogg and WF
                  Acquisition Inc. in the merger agreement that is qualified by
                  materiality is true and correct, and each representation and
                  warranty that is not qualified by materiality is true and
                  correct in all material respects, in each case, as of the
                  closing date of the merger as though made on and as of the
                  closing date or, in the case of representations and warranties
                  made as of a specified date earlier than the closing date of
                  the merger, on and as of such earlier date, and Kellogg and WF
                  Acquisition Inc. have delivered to Worthington a certificate

will not, and will not permit its subsidiary to:

         -        amend any of its corporate charter documents;

         -        declare or pay any dividends, except that Worthington may

contribution to the Worthington Foods Foundation on the date of closing of the
merger the amount of $150,000 and a house located adjacent to Worthington's
executive offices in Worthington, Ohio. The house is estimated to have a fair
market value of $260,000. These transfers will satisfy charitable commitments
made by Worthington to the Worthington Foods Foundation prior to the
commencement of merger discussions between Kellogg and Worthington. The

NO SOLICITATION

         Worthington has agreed that neither it, its subsidiary nor any of its
representatives will initiate, solicit or encourage, directly or indirectly, any
inquiries, or make or implement any proposal or offer (including any proposal or
offer to its shareholders) with respect to a merger, consolidation or other
business combination including Worthington or its subsidiary or any acquisition
or similar transaction (including a tender or exchange offer but excluding the
transactions contemplated by the merger agreement) involving the purchase of (i)
all or any significant portion of the assets of Worthington and its subsidiary
taken as a whole, (ii) 5% or more of the outstanding common shares or (iii) 5%
of the outstanding shares of the capital stock of the subsidiary of Worthington
(each referred to in the merger agreement as an Alternative Proposal). In
addition, they will not engage in any negotiations concerning, or provide any
confidential information or data to, or have any discussions with, any person or
group relating to an Alternative Proposal (excluding the transactions
contemplated by the merger agreement), or otherwise facilitate any effort or
attempt to make or implement an Alternative Proposal.

         In addition, Worthington has agreed that it will immediately cease and
cause to be terminated any existing activities, discussions or negotiations with
any parties with respect to any of the foregoing, and it will take the necessary
steps to inform such parties of these obligations. Worthington has also agreed
to notify Kellogg immediately if Worthington receives any such inquiries,
proposals or offers, requests for any such confidential information, or requests
to initiate or continue any such negotiations or discussions.

         The merger agreement provides, however, that prior to Worthington
shareholders' adoption of the merger agreement, Worthington's board of directors
may furnish information to (but only pursuant to a confidentiality agreement in
customary form) or enter into discussions or negotiations with any person or
group that makes an unsolicited bona fide Alternative Proposal, if, and only to
the extent that:

         -        the board, based on advice from outside counsel, determines in
                  good faith that such action is required for it to comply with
                  its fiduciary duties to shareholders imposed by law;

         -        the board has reasonably concluded in good faith, after
                  consultation with its financial advisor, that

                  -        if the Alternative Proposal contains cash
                           consideration, the person or group making the
                           Alternative Proposal will have adequate sources of
                           financing to consummate the Alternative Proposal,

                  -        the Alternative Proposal is more favorable to
                           Worthington's shareholders than the merger with
                           Kellogg, and

                                       52
<PAGE>   56

                  -        the board of directors receives a written opinion
                           from a nationally-recognized investment banking firm
                           to the effect that the proposed consideration in the
                           Alternative Proposal is fair, from a financial point
                           of view, to the shareholders of Worthington.

         -        prior to furnishing such information to, or entering into
                  discussions or negotiations with, such person or group,
                  Worthington provides written notice to Kellogg to the effect
                  that Worthington is furnishing information to, or entering
                  into discussions or negotiations with, another person or
                  group, which notice will identify the other person or group in
                  reasonable detail; and

         -        Worthington keeps Kellogg reasonably informed of the status
                  and substance of any such discussions or negotiations.

In addition, the board of directors may, to the extent required, comply with
Rule 14e-2 under the Securities Exchange Act of 1934 with regard to an
Alternative Proposal.

         The foregoing, however, does not (i) permit Worthington to terminate
the merger agreement (except as otherwise specifically provided in the merger
agreement), (ii) permit Worthington to enter into any agreement with respect to
an Alternative Proposal for so long as the merger agreement remains in effect,
or (iii) affect any other obligation of Worthington under the merger agreement.

         Worthington has also agreed that neither Worthington nor its subsidiary
will terminate, amend, modify or waive any provision of any confidentiality or
standstill agreement to which it is a party. Worthington will also enforce, to
the fullest extent possible under applicable law, the provisions of any such
agreement.

RIGHTS AGREEMENT

         Prior to the effective time of the merger, without the prior written
consent of Kellogg, Worthington may not amend its Rights Agreement. In addition,
except to the extent required by applicable law or to the extent that
Worthington's board of directors, based on advice from outside counsel,
determines in good faith that such action is required for the board to comply
with its fiduciary duties to shareholders imposed by law, prior to the effective
time of the merger, without the prior written consent of Kellogg, Worthington is
prohibited from taking any action with respect to, or make any determination
under, or amend Worthington's Rights Agreement. The merger agreement requires
that Worthington redeem its rights immediately prior to the effective time of
the merger. The merger agreement also provides that in the event that, following
the making of an Alternative Proposal, Worthington takes any action with respect
to the Rights Agreement which has the effect of facilitating the completion of
the Alternative Proposal or permits the Rights outstanding under the Rights
Agreement to separate from the common shares in connection with the Alternative
Proposal, then Worthington will be obligated to pay to Kellogg, by wire transfer
of funds within two business days following the date of completion of the
Alternative Proposal, the sum of $12.5 million plus expense reimbursement in an
amount not to exceed $500,000.



                                       53

         On September 30, 1999, Worthington amended the Rights Agreement,
pursuant to a First Amendment to Rights Agreement between Worthington and
National City Bank, as Rights Agent, to make the provisions of the Rights
Agreement inapplicable to the merger and the merger agreement.

         Prior to the effective time of the merger, the board of directors of
Worthington intends to redeem all outstanding Rights issued pursuant to the
Rights Agreement for a redemption price of $.0045 per Right. Presently, each
outstanding common share is accompanied by one Right.

                  agreement for two years or, to the extent that a Worthington
                  employee benefit plan is not so continued, maintain until such

                  take all actions necessary to cause WF Acquisition Inc. to
                  perform its obligations under the merger agreement and to
                  consummate the merger on the terms and conditions set forth in
                  the merger agreement;

         -        Kellogg has agreed that if it should decide following the
                  completion of the merger to discontinue or cause the
                  discontinuance of the manufacture and sale to Seventh-day
                  Organizations of a line of at least ten different vegetarian
                  products under the Loma Linda trademark, containing no meat or
                  animal-derivatives and free from black pepper or other strong
                  spices, it will give written notice of such decision to the
                  General Conference Corporation of Seventh-day Adventists and
                  offer to sell ownership of the Loma Linda trademark to the
                  General Conference Corporation of Seventh-day Adventists for a
                  purchase price of $1.00. Additionally, if for any reason,
                  Kellogg and its affiliates decide to discontinue the use of
                  the Loma Linda trademark, Kellogg will offer to sell such
                  trademark to the General Conference Corporation of Seventh-day
                  Adventists for $1.00. Seventh-day Adventist Organizations
                  refers to schools, hospitals, churches, retail food stores and
                  other organizations, entities and institutions sponsored by or
                  affiliated with the Seventh-day Adventist Church; and

         -        Each party will provide notice of and use its best efforts to
                  cure any event that causes or will cause any breach of any
                  covenant, representation or warranty in the merger agreement,
                  and each party will promptly advise the other parties of any
                  event that could have a material adverse effect on the ability
                  of any party to consummate the merger.

TERMINATION OF THE MERGER AGREEMENT

         The merger agreement may be terminated at any time prior to the
effective time of the merger:

         -        by mutual written agreement of Kellogg and Worthington;

         -        by either Kellogg or Worthington if the merger has not been
                  consummated by March 31, 2000 (provided that the right to
                  terminate will not be available to any party whose breach of
                  any obligation under the merger agreement has been the cause
                  of the failure of the merger to be consummated by March 31,
                  2000);

         -        by either party if the merger agreement is not adopted by
                  Worthington's shareholders;

         -        by either party if there has been a material breach of the
                  other party that is not curable or, if curable, has not been
                  cured within 30 days following notice;

<PAGE>   60

         -        by either party if any court or other governmental or
                  regulatory authority issues a final order making the merger
                  illegal or otherwise restricting, preventing or prohibiting
                  the merger;

         -        by Worthington if Worthington's board of directors determines
                  in good faith, based on advice from outside counsel, that
                  termination of the merger agreement is required for the board
                  to comply with its fiduciary duties to shareholders imposed by
                  law by reason of an unsolicited Alternative Proposal so long
                  as the Alternative Proposal is not conditioned on the receipt
                  of financing and other requirements are satisfied; or

         -        by Kellogg if Worthington's board of directors withdraws its
                  approval or recommendation of the merger agreement or merger,
                  modifies its approval or recommendation in a manner adverse to
                  Kellogg, recommends an Alternative Proposal to Worthington's
                  shareholders or fails to reconfirm its recommendation of the
                  merger agreement and merger following the written request of
                  Kellogg.

         If the merger agreement is terminated by either Worthington or Kellogg,
the merger agreement will become void and there will be no liability or
obligation on the part of Worthington or Kellogg or their respective
representatives or affiliates, except (i) that certain provisions (such as
confidentiality, payment of the brokers' fees and applicable termination fees
and expenses, and the enforcement of remedies) will continue to apply following
such termination, and (ii) that no such termination will relieve any party from
liability for any willful breach thereof.

         Subject to applicable law, the merger agreement may be amended,
modified or supplemented only by action taken by or on behalf of the respective
boards of directors of Worthington, Kellogg and WF Acquisition Inc. at any time
prior to the effective time of the merger, whether prior to or after the
requisite approval of Worthington's shareholders has been obtained.

TERMINATION FEES AND EXPENSES

         Worthington will be required to pay Kellogg a termination fee of $12.5
million, plus merger expenses of up to $500,000, if any person or group has made
an Alternative Proposal and the merger agreement is terminated:

         -        by Worthington because Worthington's board of directors has
                  determined in good faith, based on advice of outside counsel,
                  that termination of the merger agreement is required for the
                  board to comply with its fiduciary duties to shareholders
                  imposed by law by reason of an unsolicited Alternative
                  Proposal and all other conditions to Worthington's right to
                  terminate have been satisfied;

         -        by Kellogg because Worthington's board of directors has
                  withdrawn its approval or recommendation of the merger
                  agreement or the merger, modified

                  recommends an Alternative Proposal to Worthington's
                  shareholders or fails to reconfirm its recommendation of the
                  merger agreement and merger following the written request of
                  Kellogg;

         -        by either party because an Alternative Proposal has been made
                  and thereafter the merger agreement is not adopted by
                  Worthington's shareholders, and an agreement with respect to
                  the Alternative Proposal is executed within one year of the
                  termination of the merger agreement;

         -        by either party because an Alternative Proposal has been made
                  and thereafter the merger is not consummated by March 31,
                  2000, and an agreement with respect to the Alternative
                  Proposal is executed within one year of the termination of the
                  merger agreement; or

         -        by Kellogg because an Alternative Proposal is made and
                  thereafter the merger agreement is terminated for any other
                  reason (other than by reason of a breach by Kellogg or WF
                  Acquisition Inc.) and an agreement with respect to the
                  Alternative Proposal is executed within one year of the
                  termination of the merger agreement.


                               REGULATORY MATTERS

         Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, the
merger may not be consummated until (a) notifications have been given, and
required information has been furnished, to the Federal Trade Commission and the
Antitrust Division of the Department of Justice and (b) specified waiting period
requirements have been satisfied. In October, 1999, Worthington and Kellogg
filed the requisite pre-merger filings with these government authorities. [On
November ___, 1999, the Federal Trade Commission and The Antitrust Division of
the U.S. Department of Justice granted early termination of the waiting period
before the merger can be completed under the Hart-Scott-Rodino Antitrust
Improvements Act.

         [Add the following if appropriate -- Even though early termination of
the waiting period has been granted, the Federal Trade Commission, the Antitrust
Division or others could take action under the antitrust laws to challenge the
merger, including to enjoin the merger. The obligations of Worthington and
Kellogg to complete the merger are subject to the condition that there is no
final court order or action by a governmental or regulatory authority to
restrict, prevent or prohibit consummation of the merger.]

                         INDEPENDENT PUBLIC ACCOUNTANTS

         Since 1989, Ernst & Young LLP has served as Worthington's independent
public accountants. Worthington's board of directors expects that one or more
representatives of Ernst & Young LLP will attend the special meeting, will have
the opportunity to make statements at the special meeting if they so desire to
do so and are expected to be available to respond to appropriate questions.


                              SHAREHOLDER PROPOSALS

         In order for proposals of shareholders intended to be presented at the
annual meeting of shareholders to be held in 2000 (if the merger is not
consummated prior to such time) to be considered for inclusion in Worthington's
proxy statement and form of proxy relating to that meeting, such proposals must
be received at Worthington's executive offices on or before November 16, 1999.

         The SEC has promulgated rules related to the exercise of discretionary
voting authority pursuant to proxies solicited by Worthington's board of
directors. If a shareholder intends to submit a proposal at the 2000 annual
meeting of shareholders and does not notify Worthington of the proposal by
January 30, 2000, the proxies solicited by Worthington's board of directors for
use at the 2000 annual meeting may be voted on the proposal without discussion
of the proposal in Worthington's proxy statement for that annual meeting.

         In each case, written notice must be given to the Secretary of
Worthington, whose name and address are Ronald L. McDermott, Secretary,
Worthington Foods, Inc., 900 Proprietors Road, Worthington, Ohio 43085.


                       WHERE YOU CAN FIND MORE INFORMATION

         Worthington files annual, quarterly and special reports, proxy
statements and other information with the SEC under the Securities Exchange Act
of 1934. You may read and copy any reports, statements or other information
Worthington files at the SEC's public reference rooms at 450 Fifth Street, N.W.,

York 10048; and 500 West Madison Street, Suite 1400, Chicago, Illinois 60061.

         You may obtain information on the operation of the SEC's public
reference rooms by calling the SEC at 1-800-SEC-0330.

         The SEC also maintains an Internet website that contains reports, proxy
statements and other information regarding issuers, like Worthington, that file
electronically with the SEC. The address of that site is http://www.sec.gov.

         The SEC allows Worthington to "incorporate by reference" information
into this proxy statement. This means that we can disclose important information
to you by referring you to another document filed separately with the SEC. The
information incorporated by reference is considered to be a part of this proxy
statement, except for any information that is superseded by information that is
included directly in this proxy statement.

         This proxy statement incorporates by reference the documents listed
below that Worthington has previously filed with the SEC. They contain important
information about Worthington and its financial condition.

            CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

         The following statements are or may constitute forward-looking
statements within the meaning of the Private Securities Litigation Reform Act of
1995:

         -        Certain statements, including possible or assumed future
                  results of operations of Worthington, contained in "The
                  Merger--Background," "The Merger--Worthington's Reasons for
                  the Merger; Recommendation of the Board" and "The
                  Merger--Opinion of Financial Advisor to Worthington,"
                  including any forecasts, projections and descriptions of
                  anticipated cost savings referred to therein, and certain
                  statements incorporated by reference from documents filed with
                  the SEC by Worthington and any statements contained in this
                  proxy statement or these other documents regarding future cash
                  flows, future business prospects, revenues, working capital,
                  liquidity, capital needs, interest costs, income or the
                  effects of the merger;

         -        any statements preceded by, followed by or that include the
                  words "believes," "expects," "anticipates," "intends,"
                  "estimates," "projects" or similar expressions; and

         -        other statements contained or incorporated by reference in
                  this proxy statement regarding matters that are not historical
                  facts.

         Because these forward-looking statements are subject to risks and
uncertainties, actual results may differ materially from those expressed or
implied by the statements. Shareholders are cautioned not to place undue
reliance on these statements, which speak only as of the date of this proxy
statement.

         Among the factors that could cause actual results to defer materially
are changes in general economic conditions; fluctuation in interest rates;
increases in raw material costs; level of competition; market acceptance of new
and existing products; capital expenditure amounts; uninsured product liability;
the effective detection and remediation of Year 2000 issues by Worthington and
its key third-party vendors, suppliers and customers; and other risks detailed
from time to time in the reports filed by Worthington with the SEC.

         The cautionary statements contained or referred to in this proxy
statement should be considered in connection with any subsequent written or oral
forward-looking statements that may be issued by Worthington or persons acting
on its behalf. Except for its ongoing obligations to disclose material
information as required by the federal securities laws, Worthington undertakes
no obligation to release publicly any revisions to any forward-looking
statements to reflect events or circumstances after the date of this proxy
statement or to reflect the occurrence of unanticipated events.

               This AGREEMENT AND PLAN OF MERGER dated as of September 30, 1999
(this "Agreement") is made and entered into by and among Kellogg Company, a
Delaware corporation ("Parent"), WF Acquisition Inc., an Ohio corporation wholly
owned by Parent ("Sub"), and Worthington Foods, Inc., an Ohio corporation (the
"Company").

               WHEREAS, the Boards of Directors of Parent, Sub and the Company
have each determined that it is advisable and in the best interests of their
respective shareholders to consummate, and have approved, the business
combination transaction provided for herein in which Sub would merge with and
into the Company and the Company would become a wholly-owned subsidiary of
Parent (the "Merger");

               WHEREAS, Parent, Sub and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the
Merger and also to prescribe various conditions to the Merger;

               NOW, THEREFORE, in consideration of the mutual covenants and
agreements set forth in this Agreement, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:


                                    ARTICLE I
                                   THE MERGER

               1.01 The Merger. Upon the terms and subject to the conditions of
this Agreement, at the Effective Time (as defined in Section 1.03), Sub shall be
merged with and into the Company in accordance with the General Corporation Law
of the State of Ohio (the "OGCL"). At the Effective Time, the separate existence
of Sub shall cease and the Company shall continue as the surviving corporation
in the Merger (the "Surviving Corporation"). Sub and the Company are sometimes
referred to herein as the "Constituent Corporations". As a result of the Merger,
the outstanding shares of capital stock and the treasury shares of the
Constituent Corporations shall be converted or cancelled in the manner provided
in Article II.

               1.02 Closing. Unless this Agreement shall have been terminated
and the transactions herein contemplated shall have been abandoned pursuant to
Section 8.01, and subject to the satisfaction or waiver (where applicable) of
the conditions set forth in Article VII, the closing of the Merger (the
"Closing") will take place at the offices of Milbank, Tweed, Hadley & McCloy
LLP, 1 Chase Manhattan Plaza, New York, New York 10005 at 10:00 a.m., local
time, on the eleventh calendar day following satisfaction of the conditions set
forth in Article VII (or, if such day is not a business day, on the next
succeeding business day), unless another date, time or place is agreed to in
writing by the parties hereto (the "Closing Date"). At the Closing there shall
be delivered to Parent, Sub and the Company the certificates and other documents
and instruments required to be delivered under Article VII.

               1.03 Effective Time. At the Closing, a certificate of merger (the
"Certificate of Merger") shall be duly prepared and executed by the Constituent
Corporations and thereafter delivered to the Secretary of State of the State of
Ohio (the "Secretary of State") for filing, as
<PAGE>   76
provided in Section 1701.81 of the OGCL, as soon as practicable on the Closing
Date. The Merger shall become effective at the time of the filing of the
Certificate of Merger with the Secretary of State (the date and time of such
filing being referred to herein as the "Effective Time").

               1.04 Articles of Incorporation and Code of Regulations of the
Surviving Corporation. At the Effective Time, (i) the Articles of Incorporation
of Sub as in effect immediately prior to the Effective Time shall be amended so
that the name of Sub shall be changed to Worthington Foods, Inc., and, as so
amended, such Articles of Incorporation shall be the Articles of Incorporation
of the Surviving Corporation until thereafter amended as provided by law and
such Articles of Incorporation, and (ii) the Code of Regulations of Sub (the
"Regulations") as in effect immediately prior to the Effective Time shall be the
Regulations of the Surviving Corporation until thereafter amended as provided by
law, the Articles of Incorporation of the Surviving Corporation and such
Regulations.

               1.05 Directors and Officers of the Surviving Corporation. The
directors and officers of Sub immediately prior to the Effective Time shall,
from and after the Effective Time, be the directors and officers, respectively,
of the Surviving Corporation until their successors shall have been duly elected
or appointed and qualified or until their earlier death, resignation or removal
in accordance with the Surviving Corporation's Articles of Incorporation and
Regulations.

               1.06 Effects of the Merger. Subject to the foregoing, the effects
of the Merger shall be as provided in the applicable provisions of the OGCL.

               1.07 Further Assurances. Each party hereto will, either prior to
or after the Effective Time, execute such further documents, instruments, deeds,
bills of sale, assignments and assurances and take such further actions as may
reasonably be requested by one or more of the others to consummate the Merger,
to vest the Surviving Corporation with full title to all assets, properties,
privileges, rights, approvals, immunities and franchises of either of the
Constituent Corporations or to effect the other purposes of this Agreement.


                                   ARTICLE II
                              CONVERSION OF SHARES

               2.01 Conversion of Capital Shares. At the Effective Time, by
virtue of the Merger and without any action on the part of the holder thereof:

               (a) Conversion of Sub Shares. Each issued and outstanding common
share, without par value, of Sub ("Sub Common Shares") shall be converted into
and become one fully paid and nonassessable common share, without par value, of
the Surviving Corporation ("Surviving Corporation Common Shares"). Each
certificate representing outstanding Sub Common Shares shall at the Effective
Time represent an equal number of Surviving Corporation Common Shares.

                                       2
<PAGE>   77
               (b) Cancellation of Treasury Shares and Shares Owned by Parent
and Subsidiaries. All common shares, without par value, of the Company ("Company
Common Shares") that are owned by the Company as treasury shares and any Company
Common Shares owned by Parent, Sub or any other wholly-owned Subsidiary (as
defined in Section 9.11) of Parent shall be canceled and retired and shall cease
to exist and no stock of Parent or other consideration shall be delivered in
exchange therefor.

               (c) Exchange Ratio for Company Common Shares. (i) Each issued and
outstanding Company Common Share (other than shares to be canceled in accordance
with Section 2.01(b) and other than Dissenting Shares (as defined in Section
2.01(d))) shall be converted into the right to receive $24.00 in cash (the
"Merger Price").

                       (ii) All Company Common Shares converted in accordance
with paragraph (i) of this Section 2.01(c) shall no longer be outstanding and
shall automatically be canceled and retired and shall cease to exist, and each
holder of a certificate representing any such shares shall cease to have any
rights with respect thereto, except the right to receive the Merger Price per
share, upon the surrender of such certificate in accordance with Section 2.02,
without interest, subject to any applicable withholding tax.

               (d) Dissenting Shares. (i) Notwithstanding anything in this
Agreement to the contrary, each outstanding Company Common Share that is held of
record by a holder who has properly exercised dissenters' rights with respect
thereto under Section 1701.85 of the OGCL (a "Dissenting Share"), shall not be
converted into or represent the right to receive the Merger Price pursuant to
Section 2.01(c), but the holder thereof shall be entitled to receive such
payment of the fair cash value of such Company Common Share from the Surviving
Corporation as shall be determined pursuant to Section 1701.85 of the OGCL;
provided, however, that if any such holder shall have failed to perfect or shall
withdraw or lose such holder's rights under Section 1701.85 of the OGCL, each
such holder's Company Common Shares shall thereupon be deemed to have been
converted as of the Effective Time into the right to receive the Merger Price,
without any interest thereon, pursuant to Section 2.01(c ).

                       (ii) The Company shall give Parent (x) prompt notice of
any written demands for payment of the fair cash value of shares, withdrawals of
such demands and any other instruments delivered pursuant to Section 1701.85 of
the OGCL and (y) the opportunity to jointly participate with the Company in all
negotiations and proceedings with respect to demands for payment under Section
1701.85 the OGCL. The Company will not voluntarily make any payment with respect
to any demands delivered to the Company pursuant to Section 1701.85 and will
not, except with the prior written consent of Parent, settle or offer to settle
any such demands.

               (e) Stock Option Plans. (i) Subject to paragraph (ii) below,
immediately prior to the Effective Time, each outstanding option to acquire
Company Common Shares (the "Company Options") granted under any of the Company
Option Plans (as defined in Section 3.02(a)), whether or not then exercisable,
shall be cancelled by the Company, and in consideration of such cancellation,
the holder thereof shall be entitled to receive from the Company at the
Effective Time an amount in respect thereof equal to the product of (A) the
excess, if any, of the Merger Price per share over the per share exercise price
thereof and (B) the

                                       3
<PAGE>   78
number of Company Common Shares subject thereto (the "Option Amount") (such
payment to be net of applicable withholding taxes). Prior to the Effective Time,
the Company shall deposit in a bank account not within the Company's control an
amount of cash equal to the Option Amount for each Company Option then
outstanding (subject to any applicable withholding tax), together with
instructions that such cash be promptly distributed following the Effective Time
to the holders of such Company Options in accordance with this Section 2.01(e).

               (ii) After the date of this Agreement and prior to the Closing
Date, the Company shall use its reasonable best efforts and otherwise take all
actions reasonably necessary to implement the cash-out of the Company Options as
provided for in Section 2.01(e).

               2.02 Exchange of Certificates.

               (a) Payment Agent. At the Closing, Parent shall deposit with a
bank or trust company designated before the Closing Date by Parent and
reasonably acceptable to the Company (the "Payment Agent"), a cash amount equal
to the aggregate Merger Price to which holders of Company Common Shares shall be
entitled upon consummation of the Merger, to be held for the benefit of and
distributed to such holders in accordance with this Section. The Payment Agent
shall agree to hold such funds (such funds, together with earnings thereon,
being referred to herein as the "Payment Fund") for delivery as contemplated by
this Section and upon such additional terms as may be agreed upon by the Payment
Agent, the Company and Parent. If for any reason (including losses) the Payment
Fund is inadequate to pay the cash amounts to which holders of Company Common
Shares shall be entitled, Parent and the Surviving Corporation shall in any
event remain liable, and shall make available to the Payment Agent additional
funds, for the payment thereof. The Payment Fund shall not be used for any
purpose except as expressly provided in this Agreement.

               (b) Exchange Procedures. As soon as reasonably practicable after
the Effective Time, the Surviving Corporation shall cause the Payment Agent to
mail to each holder of record of a certificate or certificates which immediately
prior to the Effective Time represented outstanding Company Common Shares (the
"Certificates") whose shares are converted pursuant to Section 2.01(c) into the
right to receive the Merger Price (i) a letter of transmittal (which shall
specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Payment
Agent and shall be in such form and have such other provisions as the Surviving
Corporation may reasonably specify) and (ii) instructions for use in effecting
the surrender of the Certificates in exchange for the Merger Price. Upon
surrender of a Certificate for cancellation to the Payment Agent, together with
such letter of transmittal duly executed and completed in accordance with its
terms, the holder of such Certificate shall be entitled to receive in exchange
therefor a check representing the Merger Price per Company Common Share
represented thereby, subject to any applicable withholding tax, which such
holder has the right to receive pursuant to the provisions of this Article II,
and the Certificate so surrendered shall forthwith be canceled. In no event
shall the holder of any Certificate be entitled to receive interest on any funds
to be received in the Merger, including any interest accrued in respect of the
Payment Fund. In the event of a transfer of ownership of Company Common Shares
which is not registered in the transfer records of the Company, the Merger Price
may be issued to a transferee if the Certificate representing such

                                       4
<PAGE>   79
Company Common Shares is presented to the Payment Agent accompanied by all
documents required to evidence and effect such transfer and by evidence that any
applicable stock transfer taxes have been paid. Until surrendered as
contemplated by this Section 2.02(b), each Certificate shall be deemed at any
time after the Effective Time to represent only the right to receive upon such
surrender the Merger Price per Company Common Share represented thereby as
contemplated by this Article II, together with the dividends, if any, which may
have been declared by the Company on the Company Common Shares in accordance
with the terms of this Agreement and which remain unpaid at the Effective Time.
Parent and the Surviving Corporation shall pay all fees and expenses of the
Payment Agent in connection with the distribution of the Merger Price.

               (c) No Further Ownership Rights in Company Common Shares. All
cash paid upon the surrender for exchange of Certificates in accordance with the
terms hereof shall be deemed to have been paid in full satisfaction of all
rights pertaining to the Company Common Shares represented thereby, subject,
however, to the Surviving Corporation's obligation to pay any dividends which
may have been declared by the Company on such shares of Company Common Shares in
accordance with the terms of this Agreement and which remained unpaid at the
Effective Time. Unless otherwise required by Section 1701.85 of the OGCL, from
and after the Effective Time, the share transfer books of the Company shall be
closed and there shall be no further registration of transfers on the share
transfer books of the Surviving Corporation of the Company Common Shares which
were outstanding immediately prior to the Effective Time. If, after the
Effective Time, Certificates (other than Certificates representing Dissenting
Shares) are presented to the Surviving Corporation for any reason, they shall be
canceled and exchanged as provided in this Section.

               (d) Termination of Payment Fund. Any portion of the Payment Fund
which remains undistributed to the shareholders of the Company for twelve (12)
months after the Effective Time shall be delivered to the Surviving Corporation,
upon demand, and any shareholders of the Company who have not theretofore
complied with this Article II shall thereafter look only to the Surviving
Corporation (subject to abandoned property, escheat and other similar laws) as
general creditors for payment of their claim for the Merger Price per share.
Neither Parent nor the Surviving Corporation shall be liable to any holder of
Company Common Shares for cash representing the Merger Price delivered to a
public official pursuant to any applicable abandoned property, escheat or
similar law.

               (e) Withholding Rights. Parent shall be entitled to deduct and
withhold from the consideration otherwise payable pursuant to this Agreement to
any holder of Company Common Shares such amounts as Parent is required to deduct
and withhold with respect to the making of such payment under the Internal
Revenue Code of 1986, as amended (the "Code"), or any provision of state, local
or foreign tax law. To the extent that amounts are so withheld by Parent, such
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the holder of the Company Common Shares in respect of which such
deduction and withholding was made by Parent.

                                   ARTICLE III
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

               The Company represents and warrants to Parent and Sub as follows:

               3.01 Organization and Qualification. Each of the Company and its
Subsidiaries is a corporation duly incorporated, validly existing and in good
standing under the laws of its jurisdiction of incorporation and has full
corporate power and authority to conduct its business as and to the extent now
conducted and to own, use and lease its assets and properties, except for such
failures to be so incorporated, existing and in good standing or to have such
power and authority which, individually or in the aggregate, are not having and
could not be reasonably expected to have a material adverse effect (as defined
in Section 9.11) on the Company and its Subsidiaries taken as a whole. Each of
the Company and its Subsidiaries is duly qualified, licensed or admitted to do
business and is in good standing in each jurisdiction in which the ownership,
use or leasing of its assets and properties, or the conduct or nature of its
business, makes such qualification, licensing or admission necessary, except for
such failures to be so qualified, licensed or admitted and in good standing
which, individually or in the aggregate, are not having and could not be
reasonably expected to have a material adverse effect on the Company and its
Subsidiaries taken as a whole. Section 3.01 of the letter dated the date hereof
and delivered to Parent and Sub by the Company concurrently with the execution
and delivery of this Agreement (the "Company Disclosure Letter") sets forth (i)
the name and jurisdiction of incorporation of each Subsidiary of the Company,
(ii) its authorized capital shares, (iii) the number of issued and outstanding
capital shares and (iv) the record owners of such shares. Except for interests
in the Subsidiaries of the Company and as disclosed in Section 3.01 of the
Company Disclosure Letter, the Company does not directly or indirectly own any
equity or similar interest in, or any interest convertible into or exchangeable
or exercisable for, any equity or similar interest in, any corporation,
partnership, limited liability company, joint venture or other business
association or entity. The Company has previously delivered or made available to
Parent correct and complete copies of the certificate or articles of
incorporation and bylaws or code of regulations (or other comparable charter
documents) of the Company and its Subsidiaries.

               3.02 Capitalization. (a) The authorized capital shares of the
Company consists solely of 30,000,000 Company Common Shares and 2,000,000
preferred shares, without par value ("Company Preferred Shares"). As of August
31, 1999, 12,385,576 Company Common Shares were issued and outstanding, 0 shares
were held in the treasury of the Company and the only Company Common Shares
reserved for issuance as of such date consisted of (a) 158,663 shares which were
reserved or held for issuance pursuant to stock options outstanding under the
Company's 1985 Stock Option Plan, as amended, (b) 603,090 shares which were
reserved or held for issuance pursuant to stock options outstanding under the
Company's Amended and Restated 1995 Stock Option Plan and (c) 92,221 shares
which were reserved or held for issuance pursuant to stock options outstanding
under the Company's 1993 Stock Option Plan for Non-Employee Directors (such
Plans, the "Company Option Plans"). Since such date, except as set forth in
Section 3.02 of the Company Disclosure Letter, there has been no change in the
number of issued and outstanding Company Common Shares or Company Common Shares
held in treasury or reserved for issuance. As of the date hereof, no Company
Preferred Shares are issued

                                       6
<PAGE>   81
and outstanding and 300,000 shares are designated Series A Junior Participating
Preferred Shares ("Company Series A Preferred Shares") and are reserved for
issuance in accordance with the Rights Agreement dated as of June 13, 1995, as
amended, by and between the Company and National City Bank, as Rights Agent (the
"Company Rights Agreement"), pursuant to which the Company has issued rights
(the "Company Rights") to purchase Company Series A Preferred Shares. All of the
issued and outstanding Company Common Shares are, and all shares reserved for
issuance will be, upon issuance in accordance with the terms specified in the
instruments or agreements pursuant to which they are issuable, duly authorized,
validly issued, fully paid and nonassessable. Except pursuant to this Agreement
and the Company Rights Agreement, and except as set forth in Section 3.02 of the
Company Disclosure Letter, there are no outstanding subscriptions, options,
warrants, rights (including "phantom" stock rights), preemptive rights or other
contracts, commitments, understandings or arrangements, including any right of
conversion or exchange under any outstanding security, instrument or agreement
(together, "Options"), obligating the Company or any of its Subsidiaries to
issue or sell any capital shares of the Company or to grant, extend or enter
into any Option with respect thereto.

               (b) Except as disclosed in Section 3.02 of the Company Disclosure
Letter, all of the outstanding capital shares of each Subsidiary of the Company
are duly authorized, validly issued, fully paid and nonassessable and are owned,
beneficially and of record, by the Company or a Subsidiary wholly owned,
directly or indirectly, by the Company, free and clear of any liens, claims,
mortgages, encumbrances, pledges, security interests, equities and charges of
any kind (each a "Lien"). Except as disclosed in Section 3.02 of the Company
Disclosure Letter, there are no (i) outstanding Options obligating the Company
or any of its Subsidiaries to issue or sell any capital shares of any Subsidiary
of the Company or to grant, extend or enter into any such Option or (ii) voting
trusts, proxies or other commitments, understandings, restrictions or
arrangements in favor of any person other than the Company or a Subsidiary
wholly owned, directly or indirectly, by the Company with respect to the voting
of or the right to participate in dividends or other earnings on any capital
shares of any Subsidiary of the Company.

               (c) Except as disclosed in Section 3.02 of the Company Disclosure
Letter, and except as may be needed to facilitate the distribution of benefits
from the Company's Employee Stock Ownership Plan, there are no outstanding
contractual obligations of the Company or any Subsidiary of the Company to
repurchase, redeem or otherwise acquire any Company Common Shares or any capital
shares of any Subsidiary of the Company or to provide funds to, or make any
investment (in the form of a loan, capital contribution or otherwise) in, any
Subsidiary of the Company or any other person.

               3.03 Authority Relative to this Agreement. The Company has the
requisite corporate power and authority to enter into this Agreement and,
subject to obtaining the Company Shareholders' Approval (as defined in Section
6.03), to perform its obligations hereunder and to consummate the transactions
contemplated hereby. The execution, delivery and performance of this Agreement
by the Company and the consummation by the Company of the transactions
contemplated hereby have been duly and validly approved by the Board of
Directors of the Company, the Board of Directors of the Company has recommended
adoption of this Agreement by the shareholders of the Company and directed that
this Agreement be submitted to the shareholders of the Company for their

<PAGE>   82
proceedings on the part of the Company or its shareholders are necessary to
authorize the execution, delivery and performance of this Agreement by the
Company and the consummation by the Company of the transactions contemplated
hereby, other than obtaining the Company Shareholders' Approval. This Agreement
has been duly and validly executed and delivered by the Company and, subject to
the obtaining of the Company Shareholders' Approval, constitutes a legal, valid
and binding obligation of the Company enforceable against the Company in
accordance with its terms, except as enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting the enforcement of creditors' rights generally and by general
equitable principles (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

               3.04 Non-Contravention; Approvals and Consents. (a) Except as
disclosed in Section 3.04 of the Company Disclosure Letter, the execution and
delivery of this Agreement by the Company do not, and the performance by the
Company of its obligations hereunder and the consummation of the transactions
contemplated hereby will not, conflict with, result in a violation or breach of,
constitute (with or without notice or lapse of time or both) a default under,
result in or give to any person any right of payment or reimbursement,
termination, cancellation, modification or acceleration of, or result in the
creation or imposition of any Lien upon any of the assets or properties of the
Company or any of its Subsidiaries under, any of the terms, conditions or
provisions of (i) the certificates or articles of incorporation or regulations
or bylaws (or other comparable charter documents) of the Company or any of its
Subsidiaries, or (ii) subject to the obtaining of the Company Shareholders'
Approval and the taking of the actions described in paragraph (b) of this
Section, (x) any statute, law, rule, regulation or ordinance (together, "laws"),

or any of their respective assets or properties, or (y) any note, bond,
mortgage, security agreement, indenture, license, franchise, permit, concession,
contract, lease or other instrument, obligation or agreement of any kind
(together, "Contracts") to which the Company or any of its Subsidiaries is a
party or by which the Company or any of its Subsidiaries or any of their
respective assets or properties is bound, excluding from the foregoing clauses
(x) and (y) conflicts, violations, breaches, defaults, terminations,
cancellations, modifications, accelerations and creations and impositions of
Liens which, individually or in the aggregate, could not be reasonably expected
to have a material adverse effect on the Company and its Subsidiaries taken as a
whole or on the ability of the Company to consummate the transactions
contemplated by this Agreement.

               (b) Except (i) for the filing of a premerger notification report

<PAGE>   83
Constituent Corporations are qualified to do business, and (iv) as disclosed in
Section 3.04 of the Company Disclosure Letter, no consent, approval or action
of, filing with or notice to any Governmental or Regulatory Authority or other
public or private third party is necessary or required under any of the terms,
conditions or provisions of any law or order of any Governmental or Regulatory
Authority or any Contract to which the Company or any of its Subsidiaries is a
party or by which the Company or any of its Subsidiaries or any of their
respective assets or properties is bound for the execution and delivery of this
Agreement by the Company, the performance by the Company of its obligations
hereunder or the consummation of the transactions contemplated hereby, other
than such consents, approvals, actions, filings and notices which the failure to
make or obtain, as the case may be, individually or in the aggregate, could not
be reasonably expected to have a material adverse effect on the Company and its
Subsidiaries taken as a whole or on the ability of the Company to consummate the
transactions contemplated by this Agreement.

complete copy of each form, report, schedule, registration statement, definitive
proxy statement and other document (together with all amendments thereof and
supplements thereto) filed by the Company or any of its Subsidiaries with the
SEC since January 1, 1997 (as such documents have since the time of their filing
been amended or supplemented, the "Company SEC Reports"), which are all the
documents (other than preliminary material) that the Company and its
Subsidiaries were required to file with the SEC since such date. As of their
respective dates, the Company SEC Reports (i) complied as to form in all
material respects with the requirements of the Securities Act of 1933, as
amended, and the rules and regulations thereunder (the "Securities Act"), or the
Exchange Act, as the case may be, and (ii) did not contain any untrue statement
of a material fact or omit to state a 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. The audited
consolidated financial statements and unaudited interim consolidated financial
statements (including, in each case, the notes, if any, thereto) included in the
Company SEC Reports (the "Company Financial Statements") complied as to form in
all material respects with the published rules and regulations of the SEC with
respect thereto, were prepared in accordance with generally accepted accounting
principles applied on a consistent basis during the periods involved (except as
may be indicated therein or in the notes thereto and except with respect to
unaudited statements as permitted by Form 10-Q of the SEC) and fairly present
(subject, in the case of the unaudited interim financial statements, to normal,
recurring year-end audit adjustments (which are not expected to be, individually
or in the aggregate, materially adverse to the Company and its Subsidiaries
taken as a whole)) the consolidated financial position of the Company and its
consolidated subsidiaries as at the respective dates thereof and the
consolidated results of their operations and cash flows for the respective
periods then ended. Except as set forth in Section 3.05 of the Company
Disclosure Letter, each Subsidiary of the Company is treated as a consolidated
Subsidiary of the Company in the Company Financial Statements for all periods

reflected or reserved against in the balance sheet for the period ended June 30,
1999 included in the Company Financial Statements or as disclosed in Section
3.07 of the Company Disclosure Letter, neither the Company nor any of its
Subsidiaries had at such date, or has incurred since that date, any liabilities
or obligations (whether absolute, accrued, contingent, fixed or otherwise, or
whether due or to become due) of any nature that would be required by generally
accepted accounting principles to be reflected on a consolidated balance sheet
of the Company and its consolidated subsidiaries (including the notes thereto),
except liabilities or obligations (i) which were incurred in the ordinary course
of business consistent with past practice or (ii) which have not been, and could
not be reasonably expected to be, individually or in the aggregate, materially
adverse to the Company and its Subsidiaries taken as a whole.

Reports filed prior to the date of this Agreement or in Section 3.08 of the
Company Disclosure Letter, (i) there are no actions, suits, arbitrations or
proceedings pending or, to the knowledge of the Company, threatened against,
relating to or affecting, nor to the knowledge of the Company are there any
Governmental or Regulatory Authority investigations or audits pending or
threatened against, relating to or affecting, the Company or any of its
Subsidiaries or any of their respective assets and properties which,
individually or in the aggregate, could be reasonably expected to have a
material adverse effect on the Company and its Subsidiaries taken as a whole or
on the ability of the Company to consummate the transactions contemplated by
this Agreement, and (ii) neither the Company nor any of its Subsidiaries is
subject to any order of any Governmental or Regulatory Authority which,
individually or in the aggregate, is having or could be reasonably expected to
have a material adverse effect on the Company and its Subsidiaries taken as a
whole or on the ability of the Company to consummate the transactions
contemplated by this Agreement.

               3.09 Information Supplied. The proxy statement relating to the
Company Shareholders' Meeting (as defined in Section 6.03), as amended or
supplemented from time to time (as so amended and supplemented, the "Proxy
Statement"), and any other documents to be filed by the Company with the SEC or
any other Governmental or Regulatory Authority in connection with the Merger and
the other transactions contemplated hereby will not, on the date of its filing
or, in the case of the Proxy Statement, at the date it is mailed to shareholders
of the Company and at the time of the Company Shareholders' Meeting, 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 are made, not misleading, except

supplied in writing by or on behalf of Parent or Sub expressly for inclusion
therein

<PAGE>   85
and information incorporated by reference therein from documents filed by Parent
or any of its Subsidiaries with the SEC. The Proxy Statement filed by the
Company with the SEC under the Exchange Act relating to the Company
Shareholders' Meeting will comply as to form in all material respects of the
Exchange Act.

               3.10 Permits; Compliance with Laws and Orders. The Company and
its Subsidiaries hold all permits, licenses, variances, exemptions, orders and
approvals of all Governmental and Regulatory Authorities necessary for the
lawful conduct of their respective businesses (the "Company Permits"), except
for failures to hold such permits, licenses, variances, exemptions, orders and
approvals which, individually or in the aggregate, are not having and could not
be reasonably expected to have a material adverse effect on the Company and its
Subsidiaries taken as a whole. The Company and its Subsidiaries are in
compliance with the terms of the Company Permits, except failures so to comply
which, individually or in the aggregate, are not having and could not be
reasonably expected to have a material adverse effect on the Company and its
Subsidiaries taken as a whole. Except as disclosed in the Company SEC Reports
filed prior to the date of this Agreement, the Company and its Subsidiaries are
not in violation of or default under any law or order of any Governmental or
Regulatory Authority, except for such violations or defaults which, individually
or in the aggregate, are not having and could not be reasonably expected to have
a material adverse effect on the Company and its Subsidiaries taken as a whole.

               3.11 Compliance with Agreements; Certain Agreements. (a) Except
as disclosed in the Company SEC Reports filed prior to the date of this
Agreement, neither the Company nor any of its Subsidiaries nor, to the knowledge
of the Company, any other party thereto is in breach or violation of, or in

event has occurred which, with notice or lapse of time or both, could be
reasonably expected to result in a default under, (i) the certificates or
articles of incorporation or bylaws or regulations (or other comparable charter
documents) of the Company or any of its Subsidiaries or (ii) any Contract to
which the Company or any of its Subsidiaries is a party or by which the Company
or any of its Subsidiaries or any of their respective assets or properties is
bound, except in the case of clause (ii) for breaches, violations and defaults
which, individually or in the aggregate, are not having and could not be
reasonably expected to have a material adverse effect on the Company and its
Subsidiaries taken as a whole.

material Tax returns and reports required to be filed by it, or requests for
extensions to file such returns or reports have been timely filed or granted and
have not expired, and all such Tax returns and reports are complete and accurate

Company has paid on its behalf) all Taxes shown as due on such Tax returns and

               (d) No requests for waivers of the time to assess any Taxes
against the Company or any of its Subsidiaries have been granted or are pending,
except for requests with respect to such Taxes that have been adequately
reserved for in the most recent financial statements contained in the Company
SEC Reports, or, to the extent not adequately reserved, the assessment of which

the Company and its Subsidiaries taken as a whole.

Regulatory Authority are presently pending, or, to the knowledge of the Company
or any of its Subsidiaries, threatened, with regard to any Taxes or Tax returns
or reports of the Company or any of its Subsidiaries, except to the extent that
such audits or proceedings, individually or in the aggregate, would not have a
material adverse effect on the Company and its Subsidiaries taken as a whole.

               (g) Each power of attorney currently in force that has been

successor or otherwise (including, without limitation, any liability under
Treasury Regulations Section 1.1502-6 or any similar provision of state, local
or foreign law), (ii) has made any, or is obligated to make any, material
payments, or is a party to any agreement that under certain circumstances could

               3.13 Employee Benefit Plans; ERISA. (a) Except as disclosed in
Section 3.13 of the Company Disclosure Letter or as would not have a material
adverse effect on the Company and its Subsidiaries taken as a whole, (i) all
Company Employee Benefit Plans (as defined below) are and have been maintained
in compliance with all applicable requirements of law, including without
limitation ERISA (as defined below) and the Code, and (ii) neither the

                                       13
<PAGE>   88
Company nor any of its Subsidiaries has any liabilities or obligations with
respect to any such Company Employee Benefit Plans, whether accrued, contingent
or otherwise, nor to the knowledge of the Company are any such liabilities or
obligations expected to be incurred other than contribution obligations and
payment of benefits arising in the normal course under any Company Employee
Benefit Plan. Section 3.13(a)(1) of the Company Disclosure Letter lists all
Company Employee Benefit Plans. Except as specifically disclosed in Section
3.13(a)(2) of the Company Disclosure Letter, the execution of, and performance
of the transactions contemplated in, this Agreement will not (either alone or
upon the occurrence of any additional or subsequent events) constitute an event
under any Company Employee Benefit Plan that will or may result in any payment
(whether of severance pay or otherwise), acceleration, forgiveness of
indebtedness, vesting, distribution, increase in benefits or obligation to fund
benefits with respect to any employee. The only severance agreements or
severance policies applicable to the Company or any of its Subsidiaries are the
agreements and policies specifically referred to in Section 3.13(a)(3) of the
Company Disclosure Letter. Each Company Employee Benefit Plan intended to be
qualified under Section 401(a) of the Code is so qualified, has received a
favorable determination letter from the IRS, and nothing has occurred that could
adversely affect such determination.

        ERISA, at any time during the five-year period immediately preceding the
        date of this Agreement; and

        benefit plan" within the meaning of Section 3(3) of ERISA.

               (iii) "ERISA Affiliate" means any person, who on or before the

Reconciliation Act of 1985, as amended.

               (e) Except as set forth in Section 3.13(e) of the Company
Disclosure Letter, each Company Employee Benefit Plan covers only employees who
are employed by the Company or a Subsidiary (or former employees or
beneficiaries with respect to service with the Company or a Subsidiary) or
directors of the Company, so that the transactions contemplated by this
Agreement will require no spin-off of assets and liabilities or other division
or transfer of rights with respect to any such plan.

contributed to any "multiemployer plan", as that term is defined in Section 4001
of ERISA.

               (g) No event has occurred, and there exists no condition or set
of circumstances in connection with any Company Employee Benefit Plan or any
Plan sponsored by an ERISA Affiliate, under which the Company or any Subsidiary,
directly or indirectly (through any indemnification agreement or otherwise),
could reasonably be expected to be subject to any risk of material liability
under Section 409 of ERISA, Section 502(i) of ERISA, Title IV of ERISA or
Section 4975 of the Code.

               (h) No transaction contemplated by this Agreement will result in
liability to the Pension Benefit Guaranty Corporation ("PBGC") under Section
302(c)(11), 4062, 4063, 4064 or 4069 of ERISA, or otherwise, with respect to the
Company, any Subsidiary, Parent or any corporation or organization controlled by
or under common control with any of the foregoing within the meaning of Section
4001 of ERISA, and, to the knowledge of the Company, no event or condition
exists or has existed which would, or would reasonably be expected to result in
any material liability to the PBGC with respect to Parent, the Company, any
Subsidiary or any such corporation or organization. Except as set forth in
Section 3.13(h) of the Company Disclosure Schedule, no "reportable event" within
the meaning of Section 4043 of ERISA has occurred with respect to any Company
Employee Benefit Plan that is a defined benefit plan under Section 3(35) of
ERISA.

               5.02 No Solicitations. Prior to the Effective Time, the Company
agrees (a) that neither it nor any of its Subsidiaries or other affiliates
shall, and it shall use its best efforts to cause their respective
Representatives (as defined in Section 9.11) not to, initiate, solicit or
encourage, directly or indirectly, any inquiries or the making or implementation

offer) involving the purchase of (i) all or any significant portion of the

persons; provided, however, that nothing contained in this Section 5.02 shall
prohibit the Board of

                                       24
<PAGE>   99
Directors of the Company from (i) furnishing information to (but only pursuant
to a confidentiality agreement in customary form and having terms and conditions
no less favorable to the Company than the Confidentiality Agreement (as defined
in Section 6.01)) or entering into discussions or negotiations with any person
or group that makes an unsolicited bona fide Alternative Proposal, if, and only
to the extent that, prior to receipt of the Company Shareholders' Approval, (A)
the Board of Directors of the Company, based on advice of outside counsel
determines in good faith that such action is required for the Board of Directors
to comply with its fiduciary duties to shareholders imposed by law, (B) the
Board of Directors has reasonably concluded in good faith, after consultation
with its financial advisor, that (1) if such Alternative Proposal contains cash
consideration, the person or group making such Alternative Proposal will have
adequate sources of financing to consummate such Alternative Proposal and (2)
such Alternative Proposal is more favorable to the Company's shareholders than
the Merger, and the Board of Directors has received a written opinion from a
nationally-recognized investment banking firm (a copy of which shall be provided
promptly to Parent) to the effect that the consideration to be received by the
Company's shareholders in connection with such Alternative Proposal is fair,
from a financial point of view, to the shareholders of the Company, (C) prior to
furnishing such information to, or entering into discussions or negotiations
with, such person or group, the Company provides written notice to Parent to the
effect that it is furnishing information to, or entering into discussions or
negotiations with, such person or group, which notice shall identify such person
or group in reasonable detail, and (D) the Company keeps Parent informed of the
status and substance of any such discussions or negotiations; and (ii) to the
extent required, complying with Rule 14e-2 promulgated under the Exchange Act
with regard to an Alternative Proposal. Nothing in this Section 5.02 shall (x)
permit the Company to terminate this Agreement (except as specifically provided
in Article VIII), (y) permit the Company to enter into any agreement with
respect to an Alternative Proposal for so long as this Agreement remains in
effect (it being agreed that for so long as this Agreement remains in effect,
the Company shall not enter into any agreement with any person or group that
provides for, or in any way facilitates, an Alternative Proposal (other than a
confidentiality agreement under the circumstances described above)), or (z)
affect any other obligation of the Company under this Agreement.

               5.03 Company Rights Agreement. (a) Prior to the Effective Time,
without the prior written consent of Parent, the Company shall not amend the
Company Rights Agreement. Except to the extent required by applicable law or to
the extent that the Board of Directors of the Company, based on advice of
outside counsel, determines in good faith that such action is required in order
for the Board of Directors to comply with its fiduciary duties to shareholders
imposed by law, prior to the Effective Time, without the prior written consent
of Parent, the Company will not take any action with respect to, or make any
determination under, the Company Rights Agreement, except that immediately prior
to the Effective Time the Company shall redeem the Company Rights.

               (b) In the event that, following the making of an Alternative
Proposal (including an unsolicited tender offer), the Company:

                                       25
<PAGE>   100
        (i)    takes any action with respect to or makes any determination
               under, the Company Rights Agreement which has the effect of
               facilitating the consummation of such Alternative Proposal; or

        (ii)   permits a Distribution Date (as defined in the Company Rights
               Agreement) to occur in connection with such Alternative Proposal,
               and such Alternative Proposal is consummated at any time
               thereafter;

    then the Company shall pay to Parent, by wire transfer of same day funds
    within two (2) business days following the date of such consummation, the
    amounts referred to in Section 8.02(b).

               5.04 Third Party Standstill Agreements. During the period from
the date of this Agreement through the Effective Time, neither the Company nor
any of its Subsidiaries shall terminate, amend, modify or waive any provision of
any confidentiality or standstill agreement to which it is a party. During such
period, the Company shall enforce, to the fullest extent permitted under
applicable law, the provisions of any such agreement, including, but not limited
to, by obtaining injunctions to prevent any breaches of such agreements and to
enforce specifically the terms and provisions thereof in any court having
jurisdiction.


                                   ARTICLE VI

hereof to the Effective Time, (i) provide Parent and its Representatives with
full access, upon reasonable prior notice and during normal business hours, to

Subsidiaries and their respective assets, properties, books and records, but
only to the extent that such access does not unreasonably interfere with the
business and operations of the Company and its Subsidiaries, and (ii) furnish
promptly to Parent (x) a copy of each report, statement, schedule and other
document filed or received by the Company or any of its Subsidiaries pursuant to
the requirements of federal or state securities laws and each material report,

Regulatory Authority, and (y) all other information and data (including, without
limitation, copies of Contracts, Company Employee Benefit Plans and other books
and records) concerning the business and operations of the Company and its
Subsidiaries as Parent or any of such other persons reasonably may request. No
investigation pursuant to this paragraph or otherwise shall affect any
representation or warranty contained in this Agreement or any condition to the
obligations of the parties hereto. Any such information or material obtained
pursuant to this Section 6.01 that constitutes "Evaluation Material" (as such
term is defined in the letter agreement dated as of July 8, 1999 between the
Company and Parent (the "Confidentiality Agreement")) shall be governed by the
terms of the Confidentiality Agreement.

is reasonably practicable. Parent, Sub and the Company shall cooperate with each
other in the preparation of the Proxy Statement, and the Company shall notify
Parent of the receipt of any comments of the SEC with respect to the Proxy
Statement and of any requests by the SEC for any amendment or supplement thereto
or for additional information, and shall provide to Parent promptly copies of
all correspondence between the Company or any Representative of the Company and
the SEC with respect to the Proxy Statement. The Company shall give Parent and
its counsel the opportunity to review the Proxy Statement and all responses to
requests for additional information by and replies to comments of the SEC before
their being filed with, or sent to, the SEC. Each of the Company, Parent and Sub
agrees to use its best efforts, after consultation with the other parties
hereto, to respond promptly to all such comments of and requests by the SEC and
to cause the Proxy Statement to be mailed to the holders of Company Common
Shares entitled to vote at the Company Stockholders' Meeting at the earliest
practicable time.

               6.03 Approval of Shareholders. (a) The Company shall, through its
Board of Directors, duly call, give notice of, convene and hold a meeting of its
shareholders (the "Company Shareholders' Meeting") for the purpose of voting on
the adoption of this Agreement (the "Company Shareholders' Approval") as soon as
reasonably practicable after the date hereof. Subject to the exercise of
fiduciary obligations as advised by outside counsel, the Company shall, through
its Board of Directors, include in the Proxy Statement the recommendation of the
Board of Directors of the Company that the shareholders of the Company adopt
this Agreement, and shall use its best efforts to obtain such adoption. In the
event that the Company Shareholders' Approval is not obtained on the date on
which the Company Shareholders' Meeting is initially convened, the Company shall
adjourn such Company Shareholders' Meeting at least once for the purpose of
obtaining the Company Shareholders' Approval and use its best efforts during any
such adjournments to obtain the Company Shareholders' Approval.

               (b) Unless this Agreement has been earlier terminated in
accordance with its terms, the Company shall not be relieved of its obligation
under the first sentence of paragraph (a) of this Section 6.03 in the event that
its Board of Directors withdraws its recommendation of this Agreement and the
Merger.

               6.04 Regulatory and Other Approvals. Subject to the terms and
conditions of this Agreement and without limiting the provisions of Sections
6.02 and 6.03, each of the Company and Parent will proceed diligently and in
good faith to, as promptly as practicable, (a) obtain all consents, approvals or
actions of, make all filings with and give all notices to Governmental or
Regulatory Authorities or any other public or private third parties required of
Parent, the Company or any of their Subsidiaries to consummate the Merger and
the other matters contemplated hereby, and (b) provide such other information
and communications to such Governmental or Regulatory Authorities or other
public or private third parties as the other party or such Governmental or

request in connection therewith. In addition to and not in limitation of the
foregoing, each of the parties will (x) take promptly all actions necessary to
make the filings required of

                                       27

earliest practicable date with any request for additional information received
by such party or its affiliates from the Federal Trade Commission (the "FTC") or
the Antitrust Division of the Department of Justice (the "Antitrust Division")
pursuant to the HSR Act, and (z) cooperate with the other party in connection
with such party's filings under the HSR Act and in connection with resolving any
investigation or other inquiry concerning the Merger or the other matters
contemplated by this Agreement commenced by either the FTC or the Antitrust
Division or state attorneys general.

               6.05 Employee Matters.

               (a) As of the Effective Time, the Company will amend its "Tax
Savings and Profit Sharing Plan" ("Code Section 401(k) Plan") to (i) eliminate
any investment fund comprised of Company Common Shares, (ii) prohibit any
additional contributions in the form of Company Common Shares and (iii) make all
participant accounts fully vested and nonforfeitable.

               (b) As of the Effective Time, the Company will amend its Employee
Stock Ownership Plan ("ESOP") to provide that benefits will be distributed
solely in cash. Within thirty (30) days after the Effective Time, Parent will
cause the Surviving Corporation to terminate the ESOP and, as soon as
administratively practicable after that date, to take all action needed to
liquidate the ESOP by distributing its assets as provided by the terms of the
ESOP.

               (c) Except for employees covered by any collective bargaining
contract, and except as otherwise expressly provided in this Agreement, Parent
will (i) cause the Company Employee Benefit Plans (other than the Company Option
Plans and other Plans providing equity or equity-based awards) in effect at the
date of this Agreement to remain in effect until the second anniversary of the
Effective Time or (ii) to the extent that such Company Employee Benefit Plans
are not so continued, cause the Company to maintain until such date benefit
plans which are substantially comparable, in the aggregate, to the employees
covered by such Company Employee Benefit Plans on the date of this Agreement.

               (d) The Plans in which the Company's employees participate
following the Effective Time will (i) credit, for vesting and eligibility
purposes only, all service performed for the Company prior to the Effective
Time, (ii) waive any pre-existing condition exclusions and actively-at-work
requirements (other than pre-existing conditions that, as of the Effective Time,
have not been satisfied under any Company Employee Benefit Plan) and (iii)
provide that any covered expenses incurred on or before the Effective Time
during the plan year of the applicable Company Employee Benefit Plan will be
taken into account for purposes of satisfying applicable deductible, coinsurance
and maximum out-of-pocket provisions after the Effective Time to the same extent
that such expenses are taken into account for similarly situated employees of
the Parent.

               (e) On or before the Closing Date, the Company will take the
following actions:

                                       28
<PAGE>   103
               (i) The Company will make a contribution to the Code Section
401(k) Plan for the benefit of the participants in such plan in an amount equal
to 3% of each participant's base salary paid from January 1, 1999 through the
Closing Date;

               (ii) The Company will make bonus payments to the Vice Presidents,
Executive Vice President and President of the Company in amounts to be
determined as follows. If the Closing Date occurs in 1999, and as of such
Closing Date the Company has achieved its sales projections through the last day
of the month immediately preceding the month in which the Closing occurs, then
the Company will pay to each of the Vice Presidents of the Company a payment
equal to 20% of such individual's Base Salary Amount (as defined below), to the
Executive Vice President of the Company a payment equal to 30% of his Base
Salary Amount and to the President of the Company a payment equal to 40% of his
Base Salary Amount. If such sales projections are not met as provided in the
immediately preceding sentence, then the Company will pay to each of the Vice
Presidents, the Executive Vice President and the President of the Company an
amount equal to 10% of such individual's Base Salary Amount. If the Closing Date
occurs in 2000, the Company will make bonus payments to the Vice Presidents, the
Executive Vice President and the President of the Company in the manner set
forth in the immediately preceding two sentences based on whether or not the
Company's sales projections for the fiscal year ended December 31, 1999 were
achieved. For purposes of this Subsection 6.05(e)(ii), the Company's sales
projections as of the end of each month and for the fiscal year shall be based
on the latest fiscal 1999 sales projections delivered by the Company to Parent
on or before the date of this Agreement. For purposes hereof, the "Base Salary
Amount' for each relevant individual shall be the base salary paid to such
individual from January 1, 1999 through the earlier of (x) the Closing Date or
(y) December 31, 1999.

               (f) Parent will provide, or will cause the Company to provide,
Typical Outplacement Services (as defined below) to each salaried employee of
the Company who is terminated by the Company (other than for cause) within 6
months of the Closing Date. Parent or the Company will select the firm or firms
to provide such Typical Outplacement Services. For purposes hereof, "Typical
Outplacement Services" as to each eligible terminated employee shall be those
outplacement services typically provided by Parent to similarly situated
employees (based on such factors as the terminated employee's compensation and
position prior to the Closing) for whom Parent provides outplacement services.

               6.06 Indemnification; Directors' and Officers' Insurance.

               (a) From and after the Effective Time, Parent shall cause the
Surviving Corporation to indemnify, advance expenses to, and hold harmless the
present and former officers and directors of the Company and its Subsidiaries in
respect of the acts or omissions occurring prior to the Effective Time to the
extent provided under the Company's or Subsidiaries Articles (or Certificate) of
Incorporation or Regulations (or By-laws) on the date of this Agreement.

               (b) Parent and the Surviving Corporation shall, until the sixth
anniversary of the Effective Time and for so long thereafter as any claim for
insurance coverage asserted on or prior to such date has not been fully
adjudicated, cause to be maintained in effect, at no cost to

                                       29
<PAGE>   104
the beneficiaries thereof, to the extent available, the policies of directors'
and officers' liability insurance maintained by the Company and its Subsidiaries
as of the date hereof (or policies of at least the same coverage and amounts
containing terms that are no less advantageous to the insured parties) with
respect to acts or omissions occurring prior to the Effective Time; provided
that in no event shall Parent or the Surviving Corporation be obligated to
expend in order to maintain or procure insurance coverage pursuant to this
paragraph any amount per annum in excess of 200% of the amount set forth in
Section 6.06 of the Company Disclosure Letter and provided, further, that if
such insurance cannot be so maintained or obtained at such cost, Parent or the
Surviving Corporation shall maintain or obtain as much of such insurance as can
be so maintained or obtained at a cost equal to 200% of the amount set forth in
said Section 6.06 of the Disclosure Letter.

               6.07 Expenses. Except as set forth in Section 8.02, whether or
not the Merger is consummated, all costs and expenses incurred in connection
with this Agreement and the transactions contemplated hereby shall be paid by
the party incurring such cost or expense. Parent shall pay the filing fee in
connection with the filings required under the HSR Act.

               6.08 Sub. Prior to the Effective Time, Sub shall not conduct any
business or make any investments other than as specifically contemplated by this
Agreement and will not have any assets (other than a de minimis amount of cash
paid to Sub for the issuance of its stock to Parent) or any material
liabilities. Parent will take all action necessary to cause Sub to perform its
obligations under this Agreement and to consummate the Merger on the terms and
conditions set forth in this Agreement.

               6.09 Brokers or Finders. Each of Parent and the Company
represents, as to itself and its affiliates, that no agent, broker, investment

                        TERMINATION, AMENDMENT AND WAIVER

               8.01 Termination. This Agreement may be terminated, and the
transactions contemplated hereby may be abandoned, at any time prior to the
Effective Time, whether prior to or after the Company Shareholders' Approval:

               (a) By mutual written agreement of the parties hereto duly
authorized by action taken by or on behalf of their respective Boards of
Directors;

               (b) By either the Company or Parent upon written notification to
the non-terminating party by the terminating party:

                       (i) at any time after March 31, 2000 if the Merger shall
        not have been consummated on or prior to such date and such failure to
        consummate the Merger is not caused by a breach of this Agreement by the
        terminating party;

                       (ii) if the Company Shareholders' Approval shall not be
        obtained by reason of the failure to obtain the requisite vote upon a
        vote held at a meeting of such shareholders, or any adjournment thereof,
        called therefor;

                       (iii) if there has been a material breach of any
        representation, warranty, covenant or agreement on the part of the
        non-terminating party set forth in this Agreement, which breach is not
        curable or, if curable, has not been cured within thirty (30) days
        following receipt by the non-terminating party of notice of such breach
        from the terminating party; or

                       (iv) if any court of competent jurisdiction or other
        competent Governmental or Regulatory Authority shall have issued an
        order making illegal or otherwise restricting, preventing or prohibiting
        the Merger and such order shall have become final and nonappealable;

               (c) By the Company if the Board of Directors of the Company
determines in good faith, based upon advice from outside counsel, that
termination of the Agreement is

                                       34
<PAGE>   109
required for the Board of Directors to comply with its fiduciary duties to
shareholders imposed by law by reason of an unsolicited bona fide Alternative
Proposal having been made which (i) meets the requirements of clauses (A) and
(B) of Section 5.02 and (ii) is not conditioned on the receipt of financing;
provided that the Company shall have complied with the provisions of clauses (C)
and (D) of Section 5.02 and shall notify Parent within three (3) business days
of its intention to terminate this Agreement or enter into a definitive
agreement with respect to such Alternative Proposal, but in no event shall such
notice be given less than forty-eight (48) hours prior to the public
announcement of the Company's termination of this Agreement; and provided
further that the Company's ability to terminate this Agreement pursuant to this
paragraph (c) is conditioned upon the prior payment by the Company to Parent of
any amounts owed by it pursuant to Section 8.02(b); or

               (d) By Parent if the Board of Directors of the Company (or any
committee thereof) shall have withdrawn or modified in a manner adverse to
Parent its approval or recommendation of this Agreement or the Merger or shall
have recommended an Alternative Proposal to the shareholders of the Company or
failed to reconfirm its recommendation of this Agreement and the Merger within
five (5) business days following a reasonable written request for such
reconfirmation by Parent.

               8.02 Effect of Termination. (a) If this Agreement is validly
terminated by either the Company or Parent pursuant to Section 8.01, this
Agreement will forthwith become null and void and there will be no liability or
obligation on the part of either the Company or Parent (or any of their
respective Representatives or affiliates), except (i) that the provisions of
6.07 and 6.09 and this Section 8.02 will continue to apply following any such
termination, (ii) that nothing contained herein shall relieve any party hereto
from liability for willful breach of its representations, warranties, covenants
or agreements contained in this Agreement and (iii) as provided in paragraph (b)
below.

               (b) In the event that any person or group shall have made an
Alternative Proposal and thereafter (i) this Agreement is terminated (x) by the
Company pursuant to Section 8.01(c), or (y) by Parent pursuant to Section
8.01(d) or (ii) this Agreement is terminated for any other reason (other than by
reason of the breach of this Agreement by Parent or a termination by either
party pursuant to 8.01(b)(iv)) and, in the case of this clause (ii) only, a
definitive agreement with respect to such Alternative Proposal is executed
within one year after such termination, then the Company shall pay to Parent, by
wire transfer of same day funds, either on the date contemplated in Section
8.01(c) if applicable, or otherwise, within two (2) business days after such
amount becomes due, (x) a termination fee of $12,500,000 and (y) an amount up to
$500,000 to reimburse Parent and Sub for all documented out-of-pocket expenses
and fees incurred by them in connection with this Agreement and the transactions
contemplated hereby (including, without limitation, fees and expenses payable to
all banks, investment banking firms and other financial institutions and persons
and their respective agents and counsel for acting as Parent's financial advisor
with respect to, or arranging or committing to provide or providing any
financing for, the Merger).

               (c) The Company acknowledges that the agreements contained in the
preceding paragraph are an integral part of the transactions contemplated by
this Agreement and that, without these agreements, Parent and Sub would not
enter into this Agreement; accordingly,

                                       35
<PAGE>   110
if the Company fails promptly to pay the amount due pursuant to such paragraph,
and in order to obtain such payment, Parent or Sub commences a suit which
results in a judgment against the Company for the fee set forth in such
paragraph, the Company shall pay to Parent or Sub, as the case may be, its cost
and expenses (including reasonable attorneys' fees and expenses) in connection
with such suit, together with interest on the amount of the fee at the prime
rate of Citibank N.A. in effect on the date such payment was required to be
made.

               (d) In the event of a termination of this Agreement pursuant to
which a payment is made in full compliance with Section 8.02(b), the receipt of
such payment shall serve as liquidated damages with respect to any breach of
this Agreement by the party who has made such payment giving rise to such
termination, and the receipt of any such payment shall be the sole and exclusive
remedy (at law or in equity) with respect to any such breach. In the event any
action, suit, proceeding or claim is commenced or asserted by a party against
another party and/or any director or officer of such other party relating,
directly or indirectly, to this Agreement, it is expressly agreed that no party
shall be entitled to obtain any punitive, exemplary, treble, or consequential
damages of any type under any circumstances in connection with such action,
suit, proceeding or claim, regardless of whether such damages may be available
under law, the parties hereby waiving their rights, if any, to recover any such
damages in connection with any such action, suit, proceeding or claim

               8.03 Amendment. This Agreement may be amended, supplemented or
modified by action taken by or on behalf of the respective Boards of Directors
of the parties hereto at any time prior to the Effective Time, whether prior to
or after the Company Shareholders' Approval shall have been obtained, but after
such adoption and approval only to the extent permitted by applicable law. No
such amendment, supplement or modification shall be effective unless set forth
in a written instrument duly executed by or on behalf of each party hereto.

               8.04 Waiver. At any time prior to the Effective Time any party
hereto, by action taken by or on behalf of its Board of Directors, may to the
extent permitted by applicable law (i) extend the time for the performance of
any of the obligations or other acts of the other parties hereto, (ii) waive any
inaccuracies in the representations and warranties of the other parties hereto
contained herein or in any document delivered pursuant hereto or (iii) waive
compliance with any of the covenants, agreements or conditions of the other
parties hereto contained herein. No such extension or waiver shall be effective
unless set forth in a written instrument duly executed by or on behalf of the
party extending the time of performance or waiving any such inaccuracy or
non-compliance. No waiver by any party of any term or condition of this
Agreement, in any one or more instances, shall be deemed to be or construed as a
waiver of the same or any other term or condition of this Agreement on any
future occasion.

September 30, 1999



The Board of Directors
Worthington Foods, Inc.
900 Proprietors Road
Worthington, Ohio  43085-3194

Members of the Board:

You have requested our opinion (the "Opinion") as to the fairness, from a
financial point of view, to the stockholders of Worthington Foods, Inc.
("Worthington" or the "Company") of the consideration to be received in
connection with a proposed merger (the "Merger") in which a wholly owned
acquisition subsidiary ("Merger Sub") of Kellogg Company ("Kellogg") will be
merged with and into the Company. As a result of the Merger, Worthington would
become a wholly owned subsidiary of Kellogg. It is our understanding that
Worthington, Kellogg and Merger Sub will enter into an Agreement and Plan of
Merger (the "Merger Agreement") to be dated on or about September 30, 1999,
pursuant to which each share of Worthington common stock will be converted into
the right to receive $24.00 in cash (the "Merger Consideration") upon
consummation of the Merger.

U.S. Bancorp Piper Jaffray Inc., as a customary part of its investment banking
business, is engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, underwriting and secondary
distributions of securities, private placements and valuations for estate,
corporate and other purposes. We will receive a fee for rendering this Opinion
which is not contingent upon the consummation of the Merger. U.S. Bancorp Piper
Jaffray will also receive a fee for advising Worthington in connection with the
Merger which is contingent upon the consummation of the Merger. The Company has
also agreed to indemnify us against certain liabilities in connection with our
services. U.S. Bancorp Piper Jaffray makes a market in Worthington's common
stock and provides research coverage for Worthington. In the ordinary course of
our business, we and our affiliates may actively trade securities of Worthington
for our own account or the account of our customers and, accordingly, may at any
time hold a long or short position in such securities.

In arriving at our opinion, we have undertaken such review, analyses and
inquiries as we deemed necessary and appropriate under the circumstances. Among
other things, we have reviewed (i) a draft of the Merger Agreement dated
September 30, 1999, (ii) certain financial,

operating and business information related to the Company, (iii) certain
internal financial information of the Company on a stand-alone basis prepared
for financial planning purposes and furnished by Worthington's management, (iv)
to the extent publicly available, financial terms of certain acquisition
transactions involving companies operating in industries deemed similar to that
in which the Company operates, (v) certain valuation and other financial
information on selected public companies deemed comparable to the Company, and
(vi) certain publicly available financial and securities data for Worthington,
Kellogg and their respective common stocks. In addition, we had discussions with
(a) members of Worthington's management concerning the financial condition,
current operating results and business outlook for the Company on a stand-alone
basis and in combination with Kellogg, (b) members of Kellogg's management
regarding their ability to finance the aggregate Merger Consideration and (c)
both management teams regarding their reasons for entering into discussions
regarding a Merger.

We have, with your consent, relied upon and assumed the accuracy, completeness
and fairness of the financial statements and other information provided to us by
Worthington or otherwise made available to us, and have not assumed
responsibility for the independent verification of such information. With
respect to the financial statement data and other internal financial information
(including the projected financial planning data) provided to U.S. Bancorp Piper
Jaffray in connection its review of the financial aspects of the proposed
Merger, we have relied upon the assurances of the management of the Company that
such information has been prepared on a reasonable basis, and, with respect to
projected financial planning data, reflects the best currently available
estimates, and that they are not aware of any information or facts that would
make the information provided to us incomplete or misleading.

In arriving at our Opinion, we have assumed that the Merger will be consummated
on the terms described in the draft of the Merger Agreement dated September 30,
1999. We have not been requested to perform, and have not performed, any
appraisals or valuations of any specific assets or liabilities of the Company,
and have not been furnished with any such appraisals or valuations. In addition,
we express no opinion regarding the liquidation value of any entity.

This Opinion is necessarily based upon the information available to us and facts
and circumstances as they exist and are subject to evaluation on the date
hereof; events occurring after the date hereof could materially affect the
assumptions used in preparing this Opinion.

This Opinion is directed to the Board of Directors of the Company and is not
intended to be and does not constitute a recommendation to any stockholder with
respect to the Merger. We were not requested to opine as to, and this Opinion
does not address, the basic business decision to proceed with or effect the
Merger or to compare the Merger to, or consider, alternative transactions that
may have been available to the Company. This Opinion shall not be published or
otherwise used, nor shall any public references to us be made, without our

prior written approval, except as expressly contemplated in the engagement
letter dated August 20, 1999 between Worthington and U.S. Bancorp Piper Jaffray.

Based upon and subject to the foregoing and based upon such other factors as we
consider relevant, it is our opinion that, as of the date hereof, the Merger
Consideration to be received by the stockholders of Worthington Foods, Inc. is
fair to such stockholders from a financial point of view.

Sincerely,


/s/ U.S. Bancorp Piper Jaffray Inc.

                                                                      APPENDIX C


                        OHIO REVISED CODE SECTION 1701.85

 SECTION 1701.85 DISSENTING SHAREHOLDER'S DEMAND FOR FAIR CASH VALUE OF SHARES.

         (A)(1) A shareholder of a domestic corporation is entitled to relief as
a dissenting shareholder in respect of the proposals described in sections
1701.74, 1701.76, and 1701.84 of the Revised Code, only in compliance with this
section.

         (2) If the proposal must be submitted to the shareholders of the
corporation involved, the dissenting shareholder shall be a record holder of the
shares of the corporation as to which he seeks relief as of the date fixed for
the determination of shareholders entitled to notice of a meeting of the
shareholders at which the proposal is to be submitted, and such shares shall not
have been voted in favor of the proposal. Not later than ten days after the date
on which the vote on the proposal was taken at the meeting of the shareholders,
the dissenting shareholder shall deliver to the corporation a written demand for
payment to him of the fair cash value of the shares as to which he seeks relief,
which demand shall state his address, the number and class of such shares, and
the amount claimed by him as the fair cash value of the shares.

         (3) The dissenting shareholder entitled to relief under division (C) of
section 1701.84 of the Revised Code in the case of a merger pursuant to section
1701.80 of the Revised Code and a dissenting shareholder entitled to relief
under division (E) of section 1701.84 of the Revised Code in the case of a
merger pursuant to section 1701.801 [1701.80.1] of the Revised Code shall be a
record holder of the shares of the corporation as to which he seeks relief as of
the date on which the agreement of merger was adopted by the directors of that
corporation. Within twenty days after he has been sent the notice provided in
section 1701.80 or 1701.801 [1701.80.1] of the Revised Code, the dissenting
shareholder shall deliver to the corporation a written demand for payment with
the same information as that provided for in division (A)(2) of this section.

         (4) In the case of a merger or consolidation, a demand served on the
constituent corporation involved constitutes service on the surviving or the new
entity, whether the demand is served before, on, or after the effective date of
the merger or consolidation.

         (5) If the corporation sends to the dissenting shareholder, at the
address specified in his demand, a request for the certificates representing the
shares as to which he seeks relief, the dissenting shareholder, within fifteen
days from the date of the sending of such request, shall deliver to the
corporation the certificates requested so that the corporation may forthwith
endorse on them a legend to the effect that demand for the fair cash value of
such shares has been made. The corporation promptly shall return such endorsed
certificates to the dissenting shareholder. A dissenting shareholder's failure
to deliver such certificates terminates his rights as a dissenting shareholder,
at the option of the corporation, exercised by written notice sent to the
dissenting shareholder within twenty days after the lapse of the fifteen-day
period, unless a court for good cause shown otherwise directs. If shares
represented by a certificate on which such a legend has been endorsed are
transferred, each new certificate issued for them shall bear a similar legend,
together with the name of the original dissenting holder of such shares. Upon
receiving a demand for payment from a dissenting shareholder who is the record
holder of uncertificated securities, the corporation shall make an appropriate
notation of the demand for payment in its shareholder records. If uncertificated
shares for which payment has been

                                      C-1
<PAGE>   120

demanded are to be transferred, any new certificate issued for the shares shall
bear the legend required for certificated securities as provided in this
paragraph. A transferee of the shares so endorsed, or of uncertificated
securities where such notation has been made, acquires only such rights in the
corporation as the original dissenting holder of such shares had immediately
after the service of a demand for payment of the fair cash value of the shares.
A request under this paragraph by the corporation is not an admission by the
corporation that the shareholder is entitled to relief under this section.

         (B) Unless the corporation and the dissenting shareholder have come to
an agreement on the fair cash value per share of the shares as to which the
dissenting shareholder seeks relief, the dissenting shareholder or the
corporation, which in case of a merger or consolidation may be the surviving or
new entity, within three months after the service of the demand by the
dissenting shareholder, may file a complaint in the court of common pleas of the
county in which the principal office of the corporation that issued the shares
is located or was located when the proposal was adopted by the shareholders of
the corporation, or, if the proposal was not required to be submitted to the
shareholders, was approved by the directors. Other dissenting shareholders,
within that three-month period, may join as plaintiffs or may be joined as
defendants in any such proceeding, and any two or more such proceedings may be
consolidated. The complaint shall contain a brief statement of the facts,
including the vote and the facts entitling the dissenting shareholder to the
relief demanded. No answer to such a complaint is required. Upon the filing of
such a complaint, the court, on motion of the petitioner, shall enter an order
fixing a date for a hearing on the complaint and requiring that a copy of the
complaint and a notice of the filing and of the date for hearing be given to the
respondent or defendant in the manner in which summons is required to be served
or substituted service is required to be made in other cases. On the day fixed
for the hearing on the complaint or any adjournment of it, the court shall
determine from the complaint and from such evidence as is submitted by either
party whether the dissenting shareholder is entitled to be paid the fair cash
value of any shares and, if so, the number and class of such shares. If the
court finds that the dissenting shareholder is so entitled, the court may
appoint one or more persons as appraisers to receive evidence and to recommend a
decision on the amount of the fair cash value. The appraisers have such power
and authority as is specified in the order of their appointment. The court
thereupon shall make a finding as to the fair cash value of a share and shall
render judgment against the corporation for the payment of it, with interest at
such rate and from such date as the court considers equitable. The costs of the
proceeding, including reasonable compensation to the appraisers to be fixed by
the court, shall be assessed or apportioned as the court considers equitable.
The proceeding is a special proceeding and final orders in it may be vacated,
modified, or reversed on appeal pursuant to the Rules of Appellate Procedure
and, to the extent not in conflict with those rules, Chapter 2505. of the
Revised Code. If, during the pendency of any proceeding instituted under this
section, a suit or proceeding is or has been instituted to enjoin or otherwise
to prevent the carrying out of the action as to which the shareholder has
dissented, the proceeding instituted under this section shall be stayed until
the final determination of the other suit or proceeding. Unless any provision in
division (D) of this section is applicable, the fair cash value of the shares
that is agreed upon by the parties or fixed under this section shall be paid
within thirty days after the date of final determination of such value under
this division, the effective date of the amendment to the articles, or the
consummation of the other action involved, whichever occurs last. Upon the
occurrence of the last such event, payment shall be made immediately to a holder
of uncertificated securities entitled to such payment. In the case of holders of
shares represented by certificates, payment shall be made only upon and
simultaneously with the surrender to the corporation of the certificates
representing the shares for which the payment is made.

                                       C-2

<PAGE>   121

        (C) If the proposal was required to be submitted to the shareholders of
the corporation, fair cash value as to those shareholders shall be determined as
of the day prior to the day on which the vote by the shareholders was taken and,
in the case of a merger pursuant to section 1701.80 or 1701.801 [1701.80.1] of
the Revised Code, fair cash value as to shareholders of a constituent subsidiary
corporation shall be determined as of the day before the adoption of the
agreement of merger by the directors of the particular subsidiary corporation.
The fair cash value of a share for the purposes of this section is the amount
that a willing seller who is under no compulsion to sell would be willing to
accept and that a willing buyer who is under no compulsion to purchase would be
willing to pay, but in no event shall the fair cash value of a share exceed the
amount specified in the demand of the particular shareholder. In computing such
fair cash value, any appreciation or depreciation in market value resulting from
the proposal submitted to the directors or to the shareholders shall be
excluded.

         (D)(1) The right and obligation of a dissenting shareholder to receive
such fair cash value and to sell such shares as to which he seeks relief, and
the right and obligation of the corporation to purchase such shares and to pay
the fair cash value of them terminates if any of the following applies:

         (a) The dissenting shareholder has not complied with this section,
unless the corporation by its directors waives such failure;

         (b) The corporation abandons the action involved or is finally enjoined
or prevented from carrying it out, or the shareholders rescind their adoption of
the action involved;

         (c) The dissenting shareholder withdraws his demand, with the consent
of the corporation by its directors;

         (d) The corporation and the dissenting shareholder have not come to an
agreement as to the fair cash value per share, and neither the shareholder nor
the corporation has filed or joined in a complaint under division (B) of this
section within the period provided in that division.

         (2) For purposes of division (D)(1) of this section, if the merger or
consolidation has become effective and the surviving or new entity is not a
corporation, action required to be taken by the directors of the corporation
shall be taken by the general partners of a surviving or new partnership or the
comparable representatives of any other surviving or new entity.

         (E) From the time of the dissenting shareholder's giving of the demand
until either the termination of the rights and obligations arising from it or
the purchase of the shares by the corporation, all other rights accruing from
such shares, including voting and dividend or distribution rights, are
suspended. If during the suspension, any dividend or distribution is paid in
money upon shares of such class or any dividend, distribution, or interest is
paid in money upon any securities issued in extinguishment of or in substitution
for such shares, an amount equal to the dividend, distribution, or interest
which, except for the suspension, would have been payable upon such shares or
securities, shall be paid to the holder of record as a credit upon the fair cash
value of the shares. If the right to receive fair cash value is terminated other
than by the purchase of the shares by the corporation, all rights of the holder
shall be restored and all distributions which, except for the suspension, would
have been made shall be made to the holder of record of the shares at the time
of termination.
