ITEM 4.  TERMS OF THE TRANSACTION.

         (a)      Item 4(a) is hereby amended by the following:

                  The information incorporated by reference from the first
                  paragraph of "THE TENDER OFFER --Certain Conditions of the
                  Offer" of the Offer to Purchase, filed as Exhibit (d)(1), is
                  amended by deleting such information and substituting
                  therefore:

                                    Notwithstanding any other provisions of the
                           Offer, Parent shall not be required to accept for
                           payment or pay for and may delay the acceptance for
                           payment of, or the payment for, any Shares, and may
                           terminate the Offer and not accept for payment or pay
                           for any Shares, if (i) immediately prior to the
                           expiration of the Offer (as it may be extended in
                           accordance with the Offer), the Minimum Condition
                           shall not have been satisfied, (ii) any applicable
                           waiting period under the HSR Act shall not have
                           expired or been terminated prior to the expiration of
                           the Offer; (iii) any required consent, permit or
                           authorization from any regulatory or governmental
                           authority has not been obtained prior to the
                           Expiration Date; or (iv) at any time prior to the
                           Expiration Date, Parent makes a determination (which
                           shall be made in good faith) that any of the
                           following conditions exist:

ITEM 7.  PURPOSE(S), ALTERNATIVES, REASONS AND EFFECTS.

         (a)      Item 7(a) is hereby amended by the following:

                  The information incorporated by reference from the third
                  paragraph under "SPECIAL FACTORS --Purpose and Structure of
                  the Transaction" of the Offer to Purchase, filed as Exhibit
                  (d)(1), is amended by deleting such information and
                  substituting therefore:

                           The present requirements to maintain the listing of
                           the Shares on the Nasdaq National Market and
                           registration of the Shares under the Exchange Act,
                           coupled with the Company's status as a public
                           company, impose on the Company direct and indirect
                           compliance costs. Compliance with such ongoing
                           requirements imposes an administrative burden on the
                           Company, resulting in the diversion of management
                           time and resources.

                           The Parent's management estimates that the following
                           compliance, public company-related, and other costs
                           would be eliminated after consummation of the
                           Transaction:

                  THEIR RESPECTIVE ADVISORS ASSUMES ANY RESPONSIBILITY FOR THE
                  ACCURACY OF THE PROJECTIONS," which is incorporated by

                  "SPECIAL FACTORS -- Certain Projections" of the Offer to

                  information.

ITEM 9.  REPORTS, OPINIONS, APPRAISALS AND CERTAIN NEGOTIATIONS.

         (a)      Item 9(a) is hereby amended and supplemented by deleting the
                  sixth and seventh paragraphs of "SPECIAL FACTORS -- Background

                                      In November 1998, Morgan Stanley began
                           reviewing with Parent its options with respect to the
                           Company. Representatives of Morgan Stanley made a
                           presentation regarding these alternatives to Parent's
                           Board of Directors at its regular meeting on December
                           10, 1998. Morgan Stanley, among other things,
                           presented an historical overview of the Company,
                           discussed its financial condition and results of
                           operations, reviewed the stock's liquidity,
                           identified the Company's research coverage, and
                           discussed the Company's possible strategic value to
                           Parent. Morgan Stanley reviewed the following
                           strategic alternatives with Parent's Board of
                           Directors: (i) Parent continuing to hold its 49%
                           interest in the Company, (ii) sale of 100% of the
                           Company, and (iii) a Parent repurchase of the
                           remaining Company interest held by the public with a
                           potential strategic sale in the future. Morgan
                           Stanley also reviewed certain considerations such as
                           tax considerations, the Bandag settlement, the
                           revenue and earnings of the business, other potential
                           strategic buyers, estimated strategic value, cost
                           savings associated with having the Company as a
                           wholly-owned subsidiary of Parent, and the long-term
                           strategic fit with Parent. In addition, Morgan
                           Stanley reviewed the process, timelines and potential
                           after-tax proceeds associated with either a
                           repurchase of shares or an immediate sale of the
                           Company. Morgan Stanley also discussed other
                           potential economic benefits to Parent associated with
                           repurchasing the Company.

                                      Morgan Stanley was not requested to, and
                           did not, render a financial opinion regarding the
                           fairness of the consideration in the Offer and the
                           Merger. In addition, Morgan Stanley was not requested
                           to, and did not, solicit third party indications of
                           interest with respect to Parent's interest in the
                           Company. See "THE TENDER OFFER - Fees and Expenses"
                           for a description of Parent's fee arrangements with
                           Morgan Stanley in connection with the Offer and the
                           Merger.

                  Item 9(a) is also hereby amended and supplemented by reference
                  to the Morgan Stanley Dean Witter presentation to Parent's
                  Board of Directors on December 10, 1998, which is attached as
                  Exhibit (b)(2) hereto; by reference to the Stephens
                  presentation to the Special Committee on March 15, 1999, which
                  is attached as Exhibit (b)(3) hereto; and by reference to
                  Parent's letter to the Special Committee which was delivered
                  to Stephens on March 15, 1999 which is attached as Exhibit
                  (b)(4) hereto.

         (b)      Item 9(b) is hereby amended by the following:

                  The disclosure that reads: "Because such analyses are
                  inherently subject to uncertainty, none of the Company, Parent
                  or Stephens or any other person assumes responsibility if
                  future events do not conform to the judgments reflected in the
                  opinion of Stephens," which is incorporated by reference from
                  the last sentence of the second paragraph of "SPECIAL FACTORS
                  -- Opinion of Financial Advisor" of the Offer to Purchase,
                  filed as Exhibit (d)(1), is amended by deleting such
                  information and substituting therefore:

                           "Such analyses are inherently subject to uncertainty
                           and actual results could differ significantly from
                           current expectations due to a number of factors,
                           including general economic conditions; competitive
                           initiatives and pricing pressures; labor relations;
                           costs of raw material; availability and cost of
                           capital; shifts in market demand; weather conditions;
                           the performance and needs of industries served by the
                           Company's businesses; actual future costs of
                           operating expenses; self-insurance claims and
                           employee wages and benefits; actual costs of
                           continuing investments in technology; and the timing
                           and amount of capital expenditures."
