                               SUMMARY TERM SHEET

     Jem Lear Acquisition Company, Inc., a Delaware corporation, which is
referred to in this Offer to Purchase as "Purchaser," "we" or "us," is offering
to purchase (the "Offer") all of the outstanding shares of common stock, par
value $0.01 per share (the "Shares"), of Kiewit Materials Company, a Delaware
corporation (the "Company") (including any Shares that may be issued upon the
conversion of the Company's 8.028% Series 2000A Convertible Debentures due 2010,
7.35% Series 2000B Convertible Debentures due 2010, 8.25% Series 2000C
Convertible Debentures due 2010, 7.81% Series 2000D Convertible Debentures due
2010 and 6.60% Series 2001 Convertible Debentures due 2011 (collectively, the
"Debentures")), for total consideration of $17.00 per share net in cash to the
seller without interest. The following are some of the questions you, as a
stockholder of the Company, may have, along with answers to those questions. We
urge you to read the remainder of this Offer to Purchase and the Transmittal
Letter carefully because the information in this summary is not complete and
additional important information is contained in the remainder of this Offer to
Purchase and the Transmittal Letter.

Q.  WHO IS OFFERING TO BUY MY SHARES?

A.  Jem Lear Acquisition Company, Inc. is a Delaware corporation that was formed
for the purpose of making the Offer. We are a wholly owned subsidiary of Rinker
Materials Corporation, a Georgia corporation, which is referred to in this Offer
to Purchase as "Parent." Parent is an indirect, wholly owned subsidiary of CSR
Limited, incorporated in New South Wales, Australia ("Ultimate Parent"). See
"Certain Information Concerning Parent, Purchaser and Ultimate Parent." Under
the rules of the Securities and Exchange Commission (the "SEC"), Parent may also
be deemed to be making the Offer.

Q.  WHAT SHARES ARE BEING SOUGHT IN THE OFFER?

A.  We are offering to purchase all of the outstanding Shares as defined in the
opening paragraph of this Summary Term Sheet. See "Terms of the Offer."

Q.  HOW MUCH ARE YOU OFFERING TO PAY AND WHAT IS THE FORM OF PAYMENT?

A.  We are offering to pay $17.00 per Share net in cash to the seller without
interest (the "Offer Price"), subject to reduction only for any applicable
backup withholding or stock transfer taxes required by law to be withheld from
payments to you. Purchaser and Parent will not be required to pay any brokerage
fee or commission imposed by any broker, dealer, bank or other person to solicit
tenders or effect the purchase. See "Terms of the Offer" and "Fees and
Expenses."

Q.  WHY ARE YOU MAKING THIS OFFER?

A.  The Offer is the first step in Parent's plan to acquire the Company, as
provided in the Agreement and Plan of Merger (the "Merger Agreement") dated as
of July 9, 2002 among Parent, Purchaser and the Company. The Merger Agreement
provides for the merger (the "Merger") of Purchaser with and into the Company
following the purchase of Shares pursuant to the Offer. In the Merger, each
Share (other than Shares (i) held by the Company, Purchaser or Parent, or any
subsidiary of Purchaser or Parent, or (ii) as to which appraisal rights are
properly exercised under Delaware law) will be converted into the right to
receive the same consideration as is being offered to stockholders of the
Company pursuant to this Offer. See "Merger Agreement and Related
Matters -- Conversion of Shares."

Q.  DO I HAVE TO PAY ANY BROKERAGE OR SIMILAR FEES TO TENDER?

A.  As a record owner of your Shares, you will not have to pay any brokerage or
similar fees to tender Shares in the Offer. However, if your shares are pledged
to a lender, your lender may charge you a fee. You should consult your lender to
determine whether any charges will apply.

Q.  DO YOU HAVE THE FINANCIAL RESOURCES TO PAY FOR THE SHARES?

A.  We will need approximately $650 million to purchase all of the Shares and to
complete the Offer and the Merger. Parent has agreed to provide us with
sufficient funds to complete the Offer from its own resources,

                                        1


including through borrowings and under standby bank credit facilities. The Offer
is not conditioned upon any financing arrangements. See "Source and Amount of
Funds" and "Certain Conditions of the Offer."

Q.  IS YOUR FINANCIAL CONDITION RELEVANT TO MY DECISION TO TENDER IN THE OFFER?

A.  Because we are offering to pay cash for the Shares rather than stock or
other securities, because Parent has agreed to provide us with the funds needed
to complete the Offer if the conditions described in this Offer to Purchase are
satisfied, and because there are no financing contingencies related to the
Offer, we do not think our financial condition is relevant to your decision
whether to tender your Shares.

Q.  HOW LONG DO I HAVE TO TENDER IN THE OFFER?

A.  You will have until 5:00 p.m., New York City time, on September 25, 2002, to
tender your Shares in the Offer, unless the Offer is extended. See "Terms of the
Offer -- Procedures for Tendering Shares." If the Offer is extended, you will
have additional time.

Q.  CAN THE OFFER BE EXTENDED AND UNDER WHAT CIRCUMSTANCES?

A.  Yes. We have agreed that we will extend the Offer if, at the time the Offer
is scheduled to expire (including at the end of an earlier extension), any of
the conditions to the Offer have not been satisfied. However, we may not extend
the Offer past November 8, 2002 (or in certain circumstances December 8, 2002)
without the consent of the Company. See "Terms of the Offer -- Extension of the
Offer" and "Certain Conditions of the Offer."

     We may also extend the Offer if we are required to do so by the rules of
the SEC in connection with any increase in the consideration to be paid pursuant
to the Offer. See "Terms of the Offer." We may also elect to provide a
"Subsequent Offering Period," which is an additional period of time beginning
after we have purchased Shares tendered during the Offer, during which
stockholders of the Company may tender their Shares and receive the Offer Price.
See "Terms of the Offer -- Subsequent Offering Period."

Q.  HOW WILL I BE NOTIFIED IF THE OFFER IS EXTENDED?

A.  If we extend the Offer, we will inform Citibank, N.A. (the "Depositary"),
which is the depositary for the Offer, of that fact and we will make a public
announcement of the extension by not later than 9:00 a.m., New York City time,
on the first business day after the day on which the Offer was scheduled to
expire.

Q.  WHAT ARE THE MOST SIGNIFICANT CONDITIONS TO THE OFFER?

A.  We are not obligated to purchase any tendered Shares unless the number of
Shares tendered and not properly withdrawn prior to the expiration of the Offer
equals at least 90% of the Shares outstanding on a fully diluted basis at the
time of expiration of the Offer. We refer to that condition as the "Minimum
Condition." However, we may elect to amend or waive the Minimum Condition so as
to reduce the percentage of the Minimum Condition to any percentage representing
at least a majority of the Shares. The Offer is also subject to a number of
other conditions that are described more completely in this Offer to Purchase.
See "Certain Conditions of the Offer."

Q.  HOW DO I TENDER MY SHARES?

A.  To tender Shares, you must deliver the certificates representing your
Shares, together with a completed Transmittal Letter and any other documents
required, to the Depositary not later than the time the Offer expires. See
"Terms of the Offer -- Procedures for Tendering Shares."

Q.  CAN I PARTICIPATE IN THE OFFER IF I AM A DEBENTURE HOLDER?

A.  Yes. If you hold any one of five series of the Company's outstanding
Debentures, you should have received a notice from the Company regarding the
Company's redemption of your Debentures. You have until August 19, 2002 to
convert the Debentures into Shares in accordance with the procedures provided in
the Debentures, the indenture under which they were issued, and the redemption
notice issued by the Company. If you convert your Debentures into Shares, you
may tender those Shares to us as described in the Offer to Purchase.

                                        2


Q.  WHAT DO I DO IF MY SHARES ARE PLEDGED TO A BANK OR OTHER LENDER?

A.  If your Shares are pledged to a bank or other lender and you wish to tender
your Shares in the Offer, you must first contact the lender to arrange for the
delivery of the certificate representing the Shares to us. If the Offer is
completed, the Depositary will pay the Offer Price to the lender, and the lender
must represent to us that upon payment of the Offer Price, the Shares will be
free and clear of any lien or other restriction imposed by the pledge.

Q.  HOW DO I WITHDRAW PREVIOUSLY TENDERED SHARES?

A.  To withdraw Shares, you must deliver a written notice of withdrawal, or a
facsimile of one, with the required information to the Depositary while you
still have the right to withdraw the Shares. You can withdraw Shares at any time
until the Offer has expired and, if we have not agreed to accept your Shares for
payment by 5:00 p.m. on September 25, 2002, you can withdraw them at any time
after such time and date until we accept Shares for payment. If we decide to
provide a Subsequent Offering Period, we will accept Shares tendered during that
period immediately upon receipt of those Shares by the Depositary. As a result,
you will not be able to withdraw Shares tendered in the Offering during any
Subsequent Offering Period. See "Terms of the Offer" and "Withdrawal Rights."

Q.  WHAT DOES THE COMPANY'S BOARD OF DIRECTORS THINK OF THE OFFER?

A.  The Board of Directors of the Company unanimously approved the Merger
Agreement, the Offer and the Merger. The Board of Directors of the Company has
determined that the Offer and the Merger are advisable and fair to, and in the
best interests of, the stockholders of the Company and is unanimously
recommending that the stockholders of the Company accept the Offer and tender
their Shares pursuant to the Offer. In addition, the Board of Directors of the
Company waived the restrictions on transfers of Shares contained in the
Company's Restated Certificate of Incorporation to the extent necessary to
permit holders of Shares to tender their Shares in the Offer. See "Background of
the Offer" and "Merger Agreement and Related Matters."

     The Company has prepared a statement containing additional information
regarding the determination and recommendation of its Board of Directors that is
being sent to stockholders of the Company together with this Offer to Purchase.

Q.  WILL THE OFFER BE FOLLOWED BY A MERGER IF ALL THE SHARES ARE NOT TENDERED IN
    THE OFFER?

A.  Assuming that the Offer is consummated but less than all of the Shares are
tendered in the Offer, Parent will acquire complete ownership of the Company by
merging Purchaser with the Company in the Merger. Consequently, as of the
consummation of either the Offer or the Merger, as the case may be, we will own
all of the capital stock of the Company. All stockholders of the Company who
held Shares before the Merger who did not tender Shares in the Offer will
receive the same price for their Shares that we paid in the Offer, unless such
stockholders properly assert appraisal rights with respect to the Merger under
Delaware law. See "Introduction" and "Appraisal Rights."

Q.  ARE APPRAISAL (DISSENTERS') RIGHTS AVAILABLE WITH RESPECT TO THE OFFER OR
    THE MERGER?

A.  Appraisal (dissenters') rights are not available with respect to the Offer,
but they are available with respect to the Merger. If you are not in favor of
the proposed Merger, if you do not tender your Shares, and if you comply with
applicable procedures under Delaware law, you will be entitled to exercise
appraisal rights. If the Offer is completed and we purchase Shares in the Offer,
we will provide you with further information regarding the Merger, including
instructions on how to perfect your right to seek an appraisal of your Shares
under Delaware law in connection with the Merger. See "Background of the Offer,"
"Merger Agreement and Related Matters" and "Appraisal Rights."

Q.  FOLLOWING THE OFFER, WILL THE COMPANY CONTINUE AS AN SEC REPORTING COMPANY?

A.  Yes, but only until such time as the Company terminates the registration of
the Shares under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"). Following the completion of the Offer, we anticipate that there will be
so few remaining stockholders of the Company that the Company will be able to
terminate the registration of the Shares under the Exchange Act. When such
registration is terminated, the

                                        3


Company will be relieved of the duty to file proxy and information statements
under the Exchange Act, and its officers, directors and holders of more than 10%
of its stock will be relieved of the reporting requirements and "short swing"
profit provisions of Section 16 of the Exchange Act. See "Effect of the Offer on
the Company's Exchange Act Registration."

Q.  IF I DECIDE NOT TO TENDER, HOW WILL THE OFFER AFFECT MY SHARES?

A.  If the Offer is completed and you have not tendered your Shares in the
Offer, you will be entitled to receive in the Merger the same amount of cash per
Share (without interest) that you would have received had you tendered your
Shares in the Offer. Therefore, if the Offer and the Merger are completed, the
only differences to you between tendering and not tendering your Shares are that
(1) you will be paid earlier if you tender your Shares, and (2) if you choose
not to tender your Shares, you will be permitted to exercise appraisal rights
with respect to the Merger.

Q.  WHAT ARE THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE PROPOSED
    TRANSACTIONS?

A.  The receipt of the Offer Price or the merger consideration in exchange for
Shares will be a taxable transaction for U.S. federal income tax purposes and
may also be taxable under applicable state, local or foreign income or other tax
laws. You should consult your tax advisor about the particular effect the
proposed transactions will have on you. See "Certain U.S. Federal Income Tax
Consequences."

Q.  WHO CAN I TALK TO IF I HAVE QUESTIONS ABOUT THE OFFER?

A.  You can contact D.F. King & Co., Inc., which is acting as the information
agent for our Offer, as follows:

                             D.F. KING & CO., INC.

To the Stockholders of Kiewit Materials Company:

                                  INTRODUCTION

     Jem Lear Acquisition Company, Inc., a Delaware corporation (the
"Purchaser") and a wholly owned subsidiary of Rinker Materials Corporation, a
Georgia corporation ("Parent"), is offering to purchase all the issued and
outstanding shares of Common Stock, par value $0.01 per share (the "Shares"), of
Kiewit Materials Company, a Delaware corporation (the "Company") (including any
Shares that may be issued upon conversion of the Company's 8.028% Series 2000A
Convertible Debentures due 2010, 7.35% Series 2000B Convertible Debentures due
2010, 8.25% Series 2000C Convertible Debentures due 2010, 7.81% Series 2000D
Convertible Debentures due 2010 and 6.60% Series 2001 Convertible Debentures due
2011 (collectively, the "Debentures")), for total consideration (the "Offer
Price") of $17.00 per Share net to the seller in cash without interest, subject
to reduction only for any applicable backup withholding or stock transfer taxes
required by law to be withheld from payments to you, on the terms and subject to
the conditions set forth in this Offer to Purchase (the "Offer to Purchase") and
in the related transmittal letter (the "Transmittal Letter"). The tender offer
described in this Offer to Purchase is referred to as the ("Offer"). Unless the
context indicates otherwise, as used herein, references to "you" or
"Stockholders" shall mean holders of Shares and references to "we" or "us" shall
mean Purchaser.

     You will not be obligated to pay brokerage fees or commissions on the sale
of Shares pursuant to the Offer, although, as set forth in Instruction 6 of the
Transmittal Letter, any applicable stock transfer taxes required by law to be
withheld will be deducted from the Offer Price you will receive for your Shares.
If your shares are pledged, your lender may charge you a fee in connection with
your tender of Shares. If you fail to complete and sign the Substitute Form W-9
that is included in the Transmittal Letter, you may be subject to a required
U.S. federal backup income tax withholding of 30% of the gross proceeds payable
to you in the Offer. See "Terms of the Offer -- Backup Withholding." We will pay
all charges and expenses of the Depositary, and D.F. King & Co., Inc., as
information agent (the "Information Agent"), incurred in connection with the
Offer. See "Fees and Expenses."

     The board of directors of the Company (the "Board of Directors" or the
"Board") has unanimously approved the Agreement and Plan of Merger, dated as of
July 9, 2002, by and among Purchaser, Parent and the Company (the "Merger
Agreement"), the Offer and the Merger (as defined herein), determined that the
Offer and the Merger are advisable and fair to, and in the best interests of,
the Stockholders, and is unanimously recommending that the Stockholders accept
the Offer and tender their Shares to Purchaser. The factors considered by the
Board in arriving at its decision to approve the Merger Agreement, the Offer,
and the Merger and to recommend unanimously that the Stockholders accept the
Offer and tender their Shares pursuant to the Offer are described in the
Company's Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule
14D-9") filed with the Securities and Exchange Commission (the "SEC") and being
delivered to you by the Company together with this Offer to Purchase. In
addition, the Board of Directors of the Company has waived the restrictions on
transfers of Shares contained in the Company's Restated Certificate of
Incorporation (the "Restated Certificate") to the extent necessary to permit
holders of Shares to tender their Shares in the Offer.

     The Offer is being made pursuant to the Merger Agreement. The purpose of
the Offer is for Parent, through Purchaser, to acquire control of, and all of
the equity interests in, the Company. If all the conditions to the Offer are
satisfied or, to the extent permitted, waived, and we purchase Shares tendered
in the Offer, the Merger Agreement contemplates that Parent will acquire the
remaining Shares that were not tendered in the Offer (if any) by merging
Purchaser with the Company (the "Merger") in accordance with the General
Corporation Law of the State of Delaware (the "DGCL"), with the Company being
the surviving corporation (the "Surviving Corporation") as a wholly owned
subsidiary of Parent. As a result of the Merger, Purchaser will cease to exist
as a separate corporate entity.

     Pursuant to the Offer, we are not required to purchase Shares unless, among
other things, there is validly tendered and not properly withdrawn prior to the
expiration of the Offer at least 90% of the total number of outstanding Shares
on a fully diluted basis (including any Shares that may be issued upon the
conversion of

                                        5


the Debentures) at the expiration of the Offer (the "Minimum Condition").
However, Parent may agree to waive the Minimum Condition if it has acquired at
least a majority of the Shares on a fully diluted basis.

     The Company has represented to us that, as of July 9, 2002, there were
36,003,436 Shares, and no shares of the Company's preferred stock, issued and
outstanding. Also, as of that date, there were 2,118,537 Shares reserved for
issuance upon conversion of the Debentures outstanding. Based on the foregoing
and assuming (i) Parent has not waived the Minimum Condition, (ii) all of the
Debentures have been converted in full into shares, and (iii) no additional
Shares (or options, warrants or rights exercisable for, or securities
convertible into, Shares) have been issued other than as set forth above, we
would need to purchase approximately 34,309,776 Shares pursuant to the Offer for
the Minimum Condition to be satisfied.

     If the Minimum Condition and other conditions to the Offer are satisfied
(or, to the extent permitted, waived) and the Offer is consummated, we will own
a sufficient number of Shares to ensure that the Merger (if necessary) will be
approved. In addition, under the DGCL if the Minimum Condition is satisfied and
not waived by us, we will be able to cause the Merger to occur without requiring
a vote of the Stockholders. If, however, we waive the Minimum Condition to the
extent permitted under the Merger Agreement and complete the Offer, a vote of
the Stockholders will be required under the DGCL to approve the Merger, although
our ownership would guarantee approval of the Merger.

     Certain other conditions to the Offer are described in "Certain Conditions
of the Offer." We expressly reserve the right, in our sole discretion, to waive
any one or more of the conditions to the Offer in accordance with the terms of
the Merger Agreement, except that with respect to the Minimum Condition, we may
waive such condition by reducing the percentage of Shares necessary to satisfy
such condition to not less than a majority of the Shares on a fully diluted
basis.

     This Offer to Purchase and the Transmittal Letter contain important
information which should be read carefully before any decision is made with
respect to the Offer.

                               TERMS OF THE OFFER

GENERAL

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any extension or
amendment), we will purchase all Shares validly tendered and not properly
withdrawn prior to the Expiration Date. The term "Expiration Date" means 5:00
p.m., New York City time, on September 25, 2002, unless the Offer has been
extended in accordance with the terms of the Merger Agreement, in which event
the term "Expiration Date" will mean the latest time and date at which the Offer
(not including any Subsequent Offering Period (as defined below)), as so
extended, will expire. Under the Merger Agreement, we may not accept for payment
or pay for Shares in the Offer prior to September 25, 2002, and the Expiration
Date cannot be extended beyond November 8, 2002 (except as set forth in
"-- Extension of the Offer" below). We may also extend the Expiration Date for
any period required by SEC rule or regulation in connection with an increase in
the consideration to be paid in the Offer.

     If by the Expiration Date any or all of the conditions to the Offer have
not been satisfied, we may, subject to the applicable rules and regulations of
the SEC and subject to the terms of and the limitations set forth in the Merger
Agreement, (a) terminate the Offer, not pay for any Shares and return all
tendered Shares to tendering Stockholders, (b) waive or reduce all the
unsatisfied conditions and, subject to any required extension, accept for
payment and pay for all Shares validly tendered prior to the Expiration Date,
(c) extend the Offer in the manner described below and, subject to your right to
withdraw Shares, retain the Shares that have been tendered during the period or
periods for which the Offer is extended, or (d) amend the Offer.

AMENDMENT OF THE OFFER

     In the Merger Agreement, we agreed that we will not, without the prior
written consent of the Company, (a) decrease the Offer Price, (b) change the
form of consideration payable in the Offer, (c) reduce the maximum number of
Shares to be purchased in the Offer, (d) amend or waive satisfaction of the
Minimum Condition, other than to reduce the required percentage of Shares to any
percentage that is not less than a majority, (e) impose additional conditions to
the Offer in addition to those set forth in "Certain Conditions of the Offer"
(collectively, the "Offer Conditions"), or (f) amend any other condition or term
of the Offer in any manner adverse to the Stockholders.

EXTENSION OF THE OFFER

     The Merger Agreement provides that we will extend the Expiration Date from
time to time (with each such extension not to exceed ten business days) if at
the scheduled expiration date of the Offer (i) any of the Offer Conditions
(other than the Minimum Condition) have not been satisfied or waived but are
reasonably capable of being satisfied on or before November 8, 2002, or (ii) the
Minimum Condition shall not have been satisfied, or, to the extent permitted by
the Merger Agreement, waived. In the event of any such extension, the Expiration
Date shall not be extended beyond November 8, 2002 without the prior written
consent of Purchaser and the Company, except as otherwise described below
regarding an "Insurance Recovery Notice." However, under no circumstances will
the Offer expire prior to 5:00 p.m. on September 25, 2002. The Merger Agreement
also provides that, without the prior consent of the Company, we may extend the
Offer for any period required by any rule or regulation of the SEC in connection
with an increase in the consideration to be paid pursuant to the Offer, but
there can be no assurance that we will exercise our right to extend the Offer.
No interest will be paid on the Offer Price for Shares tendered, whether or not
we exercise our right to extend the Offer. The foregoing rights and obligations
are in addition to our rights pursuant to "Certain Conditions of the Offer."

     Any extension, amendment, delay, waiver or termination will be followed as
promptly as practicable by public announcement. In the case of an extension,
Rule 14e-1(d) under the Exchange Act requires that the announcement be issued no
later than 9:00 a.m., New York City time, on the next business day after the
previously scheduled Expiration Date, in accordance with the public announcement
requirements of

                                        7


Rule 14d-4(d) under the Exchange Act. Subject to applicable law (including Rules
14d-4(d) and 14d-6(c) under the Exchange Act, which require that any material
changes be promptly disseminated to holders of Shares), we will have no
obligation to publish, advertise or otherwise communicate any such public
announcement other than by making a release to a national news service. As used
in this Offer to Purchase, "business day" has the meaning set forth in Rule
14d-1(g)(3) under the Exchange Act.

     If we make a material change in the terms of the Offer, the information
concerning the Offer, or waive a material condition of the Offer, we will extend
it to the extent required by Rule 14e-1 under the Exchange Act.

     If there shall have occurred any event, or the disclosure of any act,
omission, fact or circumstance, that individually or when considered together
with any other matter, may have a Material Adverse Effect (as defined in "Merger
Agreement and Related Matters - Termination - Certain Material Adverse
Effects"), and the Company has a claim for an insurance recovery for any such
occurrence, which, if paid (or if the carrier accepts coverage for such claim),
would result in there being no Material Adverse Effect, then such occurrence
shall not be deemed for the purpose of the Merger Agreement to constitute a
Material Adverse Effect until the carrier of any applicable insurance has
provided a final written notice to the Company of whether coverage of any such
claim or any portion thereof for which a recovery is being sought will be
unconditionally accepted or denied (an "Insurance Recovery Notice"). In the
event that an Insurance Recovery Notice is provided, the Expiration Date will be
extended to ten business days after the date on which such Insurance Recovery
Notice is obtained, but in no event shall the date be extended beyond December
8, 2002, and all references in the Merger Agreement and this Offer to Purchase
to the date "November 8, 2002" shall be so modified to reflect such extension.
See "Merger Agreement and Related Matters -- Termination -- Certain Material
Adverse Effects."

CONSEQUENCES OF MATERIAL CHANGES IN THE OFFER

     If we make a material change in the terms of the Offer or the information
concerning the Offer or if we waive a material condition of the Offer, we will
extend the Offer and disseminate additional tender offer materials to the extent
required by Rules 14d-4(d), 14d-6(c) and 14e-1 under the Exchange Act. The
minimum period during which the Offer must remain open following material
changes in the terms of the Offer or information concerning the Offer, other
than a change in price or a change in the percentage of securities sought, will
depend upon the facts and circumstances then existing, including the relative
materiality of the changed terms or information. With respect to a change in
price or a change in the percentage of securities sought, the Offer must remain
open for a minimum period of ten business days.

SUBSEQUENT OFFERING PERIOD

     Pursuant to Rule 14d-11 under the Exchange Act and the Merger Agreement, we
may, subject to certain conditions, provide a Subsequent Offering Period from
three to five business days in length following the Expiration Date (a
"Subsequent Offering Period"). A Subsequent Offering Period is an additional
period of time, following the expiration of the Offer and the purchase of Shares
in the Offer, during which you may tender Shares not previously tendered into
the Offer. Shares tendered during the Subsequent Offering Period may not be
withdrawn. See "Withdrawal Rights." We will immediately accept for payment, and
promptly pay for, all validly tendered Shares as they are received during the
Subsequent Offering Period. We may elect to provide a Subsequent Offering Period
by giving oral or written notice of such Subsequent Offering Period to the
Depositary. If we decide to provide a Subsequent Offering Period, we will make
an announcement to that effect by issuing a press release to a national news
service on the next business day after the previously scheduled Expiration Date.

     Rule 14d-11 provides that we may provide a Subsequent Offering Period so
long as, among other things, (i) the initial offering period (which will expire
on September 25, 2002, unless extended) has expired, (ii) we offer the same form
and amount of consideration for Shares in the Subsequent Offering Period as in
the initial Offer, (iii) we immediately accept and promptly pay for all Shares
tendered during the initial offering period prior to its expiration, (iv) we
announce the results of the Offer, including the approximate number and

                                        8


percentage of Shares deposited in the Offer, no later than 9:00 a.m. Eastern
time on the next business day after the Expiration Date and immediately begin
the Subsequent Offering Period, (v) the Offer is for all outstanding Shares and
(vi) we immediately accept and promptly pay for all Shares as they are tendered
during the Subsequent Offering Period.

     If we extend the Offer or if we are delayed in our acceptance for payment
of or payment (whether before or after our acceptance for payment of Shares) for
Shares or we are unable to pay for Shares pursuant to the Offer for any reason,
then, without prejudice to our rights under the Offer, the Depositary may retain
tendered Shares on our behalf, and such Shares may not be withdrawn except to
the extent tendering Stockholders are entitled to withdrawal rights as described
in "Withdrawal Rights." However, our ability to delay the payment for Shares we
have accepted for payment is limited by Rule 14e-1(c) under the Exchange Act,
which requires that a bidder pay the consideration offered or return the
securities tendered by or on behalf of holders of securities promptly after the
termination or withdrawal of such bidder's Offer.

MAILING OF THE OFFER

     The Company has provided us with the names and addresses of all
Stockholders and holders of Debentures for the purpose of disseminating this
Offer to Purchase to Stockholders and, to the extent they decide to exercise
their conversion rights, holders of Debentures. We will mail or cause to be
mailed this Offer to Purchase, the related Transmittal Letter and other relevant
materials to record holders of Shares and Debentures.

PROCEDURES FOR TENDERING SHARES

     Valid Tender.  For you to validly tender Shares in the Offer, you must
deliver to the Depositary at one of its addresses set forth on the back cover
page of this Offer to Purchase prior to the Expiration Date (a) a properly
completed and duly executed Transmittal Letter (or facsimile thereof), together
with any required signature guarantees, (b) all certificates representing the
Shares to be tendered ("Share Certificates"), and (c) any other documents
required by the Transmittal Letter. Persons who hold Debentures and wish to
tender the Shares that they may receive upon the conversion of such Debentures
must first properly exercise such conversion rights. See "-- Procedures for
Tendering Shares -- Special Procedures for Holders of Debentures."

     Signature Guarantees.  No signature guarantee is required on the
Transmittal Letter if the Transmittal Letter is signed by the registered holder
of Shares tendered therewith and such registered holder has not completed either
the box entitled "Special Delivery Instructions to be Completed by Pledgees and
Others" or the box entitled "Special Payment Instructions to be Completed by
Pledgees and Others" on the Transmittal Letter. If a signature guarantee is
required, a bank, savings and loan association or brokerage firm that is a
participant in the Securities Transfer Agents Medallion Program, or a bank,
broker, dealer, credit union, savings association or other entity which is an
"eligible guarantor institution" as such term is defined under the Exchange Act
(each such institution, an "Eligible Institution"), must guarantee all
signatures on the Transmittal Letter. See Instructions 1 and 5 of the
Transmittal Letter and "-- Procedures for Tendering Shares -- Special Procedures
for Holders of Pledged Shares."

     If Share Certificates are registered in the name of a person other than the
signer of the Transmittal Letter, or if payment is to be made, or Share
Certificates for Shares not tendered or not accepted for payment are to be
returned, to a person other than the registered holder of the Share Certificates
surrendered, the tendered Share Certificates must be endorsed or accompanied by
appropriate stock powers, in either case signed exactly as the name or names of
the registered holders appear on the Share Certificates, with the signatures on
the Share Certificates, stock powers and the Transmittal Letter guaranteed as
described above. See Instructions 1 and 5 of the Transmittal Letter.

     If Share Certificates are forwarded to the Depositary in multiple
deliveries, a properly completed and duly executed Transmittal Letter (or a
facsimile thereof) with all requisite signature guarantees must accompany each
such delivery.

                                        9


     Notwithstanding any other provision of the Offer, we will pay for Shares
only after timely receipt by the Depositary of (a) Share Certificates for such
Shares, (b) a Transmittal Letter (or facsimile thereof), properly completed and
duly executed, with any required signature guarantees, and (c) any other
documents required by the Transmittal Letter. Accordingly, tendering
Stockholders may be paid at different times depending upon when Share
Certificates with respect to Shares are actually received by the Depositary.

     Under no circumstances will we pay interest on the Offer Price of the
Shares, regardless of any extension of the Offer or any delay in making such
payment.

     Our acceptance for payment of Shares validly tendered pursuant to the Offer
will constitute a binding agreement between the tendering Stockholder and us
upon the terms and subject to the conditions of the Offer.

     Appointment as Proxy.  By executing a Transmittal Letter as set forth
above, you are irrevocably appointing our designees as your attorneys-in-fact
and proxies in the manner set forth in the Transmittal Letter, each with full
power of substitution, to the full extent of your rights with respect to the
Shares that you tender and that we accept for payment and with respect to any
and all other Shares or other securities or rights issued or issuable in respect
of such Shares on or after the date of this Offer to Purchase, July 23, 2002
(the "Applicable Date"). All such proxies will be irrevocable and considered
coupled with an interest in the tendered Shares. This appointment will be
effective when, and only to the extent that we accept such Shares for payment
pursuant to the Offer. Upon such acceptance for payment, all prior powers of
attorney, proxies and consents given by you with respect to such Shares or other
securities or rights will, without further action, be revoked and no subsequent
powers of attorney, proxies, consents or revocations may be given (and, if
given, will not be deemed effective). Our designees will be empowered to
exercise all voting and other rights with respect to the Shares and other
securities or rights in respect of any annual, special, adjourned or postponed
meeting of the Stockholders, actions by written consent in lieu of any such
meeting or otherwise, as they in their sole discretion deem proper. We reserve
the right to require that, in order for Shares to be deemed validly tendered,
immediately upon our acceptance for payment of such Shares, we must be able to
exercise full voting, consent and other rights with respect to such Shares and
other securities or rights, including voting at any meeting of Stockholders. The
foregoing proxies are effective only upon acceptance for payment of Shares
pursuant to the Offer. The Offer does not constitute a solicitation of proxies,
absent a purchase of Shares, for any meeting of the Company's Stockholders,
which will be made only pursuant to separate proxy solicitation materials
complying with the Exchange Act.

     Determination of Validity.  All questions as to the validity, form,
eligibility (including time of receipt) and acceptance for payment of any tender
of Shares will be determined by us, in our sole discretion, which determination
will be final and binding on all parties. We reserve the absolute right to
reject any or all tenders determined by us not to be in proper form or the
acceptance for payment of or payment for which may, in the opinion of our
counsel, be unlawful. We also reserve the absolute right to waive any condition
of the Offer (to the extent permitted by the Merger Agreement) or any defect or
irregularity in the tender of any Shares of any particular Stockholder whether
or not similar defects or irregularities are waived in the case of other
Stockholders. No tender of Shares will be deemed to have been validly made until
all defects or irregularities relating thereto have been cured or waived. None
of Purchaser, Parent, the Depositary, the Information Agent or any other person
will be under any duty to give notification of any defects or irregularities in
tenders or incur any liability for failure to give any such notification.
Subject to the terms of the Merger Agreement, our interpretation of the terms
and conditions of the Offer (including the Transmittal Letter and its
instructions) will be final and binding on all parties.

     Backup Withholding.  In order to avoid "backup withholding" of U.S. federal
income tax on payments of cash pursuant to the Offer, you must, unless an
exemption applies, provide the Depositary with your correct taxpayer
identification number ("TIN") on a Substitute Form W-9 and certify under
penalties of perjury that such TIN is correct and that you are not subject to
backup withholding. If you do not provide your correct TIN or you fail to
provide the certifications described above, the Internal Revenue Service (the
"IRS") may impose a penalty on you and the payment of cash to you pursuant to
the Offer may be subject to backup withholding of 30% of the amount of such
payment. All Stockholders surrendering Shares pursuant to the

                                        10


Offer should complete and sign the main signature form and the Substitute Form
W-9 included as part of the Transmittal Letter to provide the information and
certification necessary to avoid backup withholding (unless an applicable
exemption exists and is proved in a manner satisfactory to us and the
Depositary).

     Noncorporate foreign Stockholders should complete and sign the main
signature form and, if eligible, a Certificate of Foreign Status, Form W-8BEN, a
copy of which may be obtained from the Depositary, in order to avoid backup
withholding. See Instruction 10 to the Transmittal Letter.

     Special Procedures for Holders of Debentures.  All of the Company's
outstanding series of Debentures are convertible into Shares, under certain
circumstances, including during the 30-day period preceding the date the
Debentures have been called for redemption by the Company. A total of 2,118,537
Shares have been reserved for issuance upon conversion of the Debentures into
Shares.

     On July 15, 2002, the Company issued a notice (the "Redemption Notice") to
redeem all of the outstanding Debentures on August 19, 2002 (the "Redemption
Date") at 100% of the principal amounts thereof, with interest accrued to the
Redemption Date (the "Redemption Price"). This Redemption Notice was separately
mailed by the Company to the holders of the Debentures. Accordingly, the holders
of Debentures may exercise their right to convert their Debentures into Shares
during the 30-day period ending on August 19, 2002. If a Debenture is not timely
converted into Shares, the holder of the Debenture will receive payment of the
Redemption Price.

     In order for a holder of Debentures to tender in the Offer any or all
Shares that may be acquired by that holder upon a conversion of Debentures, the
holder must first properly exercise his or her conversion rights in accordance
with the terms of Debentures, the indenture under which the Debentures were
issued and the Redemption Notice. The conversion procedure is detailed in the
Redemption Notice and the form of Conversion Notice that accompanied the
Redemption Notice. Once the conversion rights are properly exercised and the
Company has issued to the holder a certificate evidencing the Shares issued upon
conversion of such Debentures, the holder may then comply with the terms of this
Offer and tender those Shares to Purchaser as otherwise described in
"-- Procedures for Tendering Shares."

     Special Procedures for Holders of Pledged Shares.  If Shares are pledged to
a bank, financial institution or other lender (a "Pledgee") as collateral for
money borrowed, and the Stockholder wishes to tender such Shares in the Offer,
he or she must first contact the Pledgee to help complete the Transmittal Letter
and to arrange for the delivery of his or her Share Certificates to us. Subject
to, and effective upon, acceptance for payment of the Shares tendered in the
Offer and the delivery to the Pledgee of the Offer Price for all Shares
purchased from the Stockholder, the Pledgee must agree to (i) cancel and
terminate any pledge agreement and all other security interests arising with
respect to the Shares, (ii) have no rights with respect to the Shares, and (iii)
cancel and terminate any other restrictions with respect to the Shares that
would prevent or restrict the consummation of the Offer or our ability to
receive all benefits and otherwise exercise all rights of beneficial ownership
of such Shares and all distributions related thereto.

     If the Shares are not purchased pursuant to the Offer for any reason, then
(i) the Share Certificates for any such unpurchased Shares will be returned to
the Pledgee, without expense to Pledgee and as promptly as practicable after the
expiration, termination or withdrawal of the Offer and (ii) the cancellations,
terminations and agreements set forth in the previous paragraph will be of no
force and effect whatsoever with respect to such unpurchased Shares. All
signatures on the Transmittal Letter with respect to pledged Shares must be
guaranteed as described in "-- Procedures for Tendering Shares -- Signature
Guarantees" above in accordance with the instructions to the Transmittal Letter.
Failure to follow these procedures will render any purported tender of Shares
ineffective.

                                        11


                               WITHDRAWAL RIGHTS

     Except as otherwise described in this section, tenders of Shares made in
the Offer are irrevocable. You may withdraw Shares that you previously tendered
in the Offer at any time prior to the Expiration Date and, unless previously
accepted for payment pursuant to the Offer, such Shares may also be withdrawn at
any time after September 20, 2002 (except with respect to any Subsequent
Offering Period, in which case no Shares may be withdrawn).

     For your withdrawal to be effective, you must timely deliver to the
Depositary a notice of withdrawal by facsimile, hand delivery or overnight
courier as set forth on the back cover page of this Offer to Purchase. This
notice must specify the name of the person having tendered the Shares to be
withdrawn, the number of Shares to be withdrawn and the name of the registered
holder of the Shares to be withdrawn, if different from the name of the person
who tendered the Shares. If Share Certificates have been delivered or otherwise
identified to the Depositary, then, prior to the physical release of such Share
Certificates, the serial numbers shown on such Share Certificates must be
submitted to the Depositary and, unless such Shares have been tendered by an
Eligible Institution, the signatures on the notice of withdrawal must be
guaranteed by an Eligible Institution.

     You may not rescind a withdrawal of Shares, and any Shares that you
properly withdraw will be considered not validly tendered for purposes of the
Offer. However, you may retender withdrawn Shares by again following one of the
procedures described in "Procedures for Tendering Shares" at any time prior to
the Expiration Date.

     All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by us, in our sole discretion, which
determination will be final and binding. None of Purchaser, Parent, the
Depositary, the Information Agent or any other person will be under any duty to
give notification of any defects or irregularities in any notice of withdrawal
or incur any liability for failure to give any such notification.

     If we extend the Offer or if we are delayed in our acceptance for payment
of or payment (whether before or after our acceptance for payment of Shares) for
Shares or we are unable to pay for Shares pursuant to the Offer for any reason,
then, without prejudice to our rights under the Offer, the Depositary may retain
tendered Shares on our behalf, and such Shares may not be withdrawn except to
the extent tendering Stockholders are entitled to withdrawal rights as described
in this section. However, our ability to delay the payment for Shares that we
have accepted for payment is limited by Rule 14e-1(c) under the Exchange Act,
which requires that a bidder pay the consideration offered or return the
securities tendered by or on behalf of holders of securities promptly after the
termination or withdrawal of such bidder's offer.

     If we provide a Subsequent Offering Period following the Offer, no
Withdrawal Rights will apply to Shares tendered during such Subsequent Offering
Period or to Shares tendered in the Offer and accepted for payment.

                       ACCEPTANCE FOR PAYMENT AND PAYMENT

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such extension
or amendment), we will purchase, by accepting for payment and paying for, all
Shares validly tendered and not withdrawn (as permitted by "Withdrawal Rights")
promptly after the Expiration Date. Subject to the terms of the Merger
Agreement, we will determine all questions as to the satisfaction of such terms
and conditions in our sole discretion, and our determination will be final and
binding on all parties. We expressly reserve the right, in our sole discretion,
to delay acceptance for payment of or payment for Shares in order to comply in
whole or in part with any applicable law. Any such delays will be effected in
compliance with Rule 14e-1(c) under the Exchange Act (relating to a bidder's
obligation to pay for or return tendered securities promptly after the
termination or withdrawal of such bidder's Offer).

                                        12


     In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after timely receipt by the Depositary of (a) Share
Certificates for such Shares, (b) a Transmittal Letter (or facsimile thereof),
properly completed and duly executed, with any required signature guarantees,
and (c) any other documents required by the Transmittal Letter.

     For purposes of the Offer, we will be considered to have accepted for
payment, and thereby purchased, Shares validly tendered as, if and when we give
written notice to the Depositary of our acceptance for payment such validly
tendered Shares. Payment for Shares accepted for payment pursuant to the Offer
will be made by deposit of the Offer Price with the Depositary, which will act
as agent for validly tendering Stockholders for the purpose of receiving payment
from us and transmitting payment to tendering Stockholders.

     Under no circumstances will we pay interest on the Offer Price regardless
of any extension of the Offer or any delay in making such payment.

     Upon the deposit of all required funds with the Depositary for the purpose
of making payments in full to tendering Stockholders, our obligation to make
such payment shall be satisfied and tendering Stockholders must thereafter look
solely to the Depositary (and, in the case of pledged Shares, the Pledgee) for
payment of amounts owed to them by reason of the acceptance for payment of
Shares pursuant to the Offer. Any amounts related to applicable backup
withholding or stock transfer taxes required by law to be withheld from payments
to a Stockholder in connection with the transfer and sale to us of Shares
pursuant to the Offer shall be paid out of the Offer Price for those Shares. We
will pay all charges and expenses of the Depositary and the Information Agent.

     If we are delayed in our acceptance for payment of or payment for Shares or
we are unable to accept for payment or pay for Shares pursuant to the Offer for
any reason, then, without prejudice to our rights under the Offer (but subject
to compliance with Rule 14e-1(c) under the Exchange Act), the Depositary may,
nevertheless, on our behalf, retain tendered Shares, and such Shares may not be
withdrawn except to the extent tendering Stockholders are entitled to exercise,
and duly exercise, withdrawal rights as described in "Withdrawal Rights."

     If we do not purchase any tendered Shares pursuant to the Offer for any
reason, we will return Share Certificates for any such unpurchased Shares,
without expense to you and as promptly as practicable after the expiration,
termination or withdrawal of the Offer.

     If prior to the expiration date, we increase the price offered to holders
of Shares in the Offer, we will pay the increased price to all holders of Shares
that are purchased in the Offer, whether or not such Shares were tendered prior
to the increase in price.

     If we provide a Subsequent Offering Period following the Offer, we will
immediately accept and promptly pay for all Shares as they are tendered in the
Subsequent Offering Period.

                                        13


                  CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES

     The following is a summary of the material U.S. federal income tax
consequences of the sale of Shares pursuant to the Offer and the exchange of
Shares for cash pursuant to the Merger. This summary does not purport to be a
description of all tax consequences that may be relevant to you, and assumes an
understanding of tax rules of general application. It does not address special
rules, which may apply to you based on your tax status, individual circumstances
or other factors unrelated to the Offer or the Merger. It also does not address
the applicability or consequences arising under any foreign (non-U.S.) tax laws
or rules. You are encouraged to consult your own tax advisors regarding the
Offer and the Merger.

GENERAL

     Your receipt of cash for Shares in the Offer or the Merger will be a
taxable transaction for U.S. federal income tax purposes, and may also be
taxable under applicable state, local, foreign and other tax laws. For U.S.
federal income tax purposes, if you sell or exchange your Shares in the Offer or
the Merger you would generally recognize gain or loss equal to the difference
between the amount of cash received and your tax basis for the Shares that you
sold or exchanged. The gain or loss will be a capital gain or loss if the Shares
are held as capital assets by you and will be a long-term capital gain or loss
if your holding period for U.S. federal income tax purposes is more than one
year at the time of the sale or exchange. Long-term capital gain of a
non-corporate Stockholder is generally subject to a maximum federal tax rate of
20%. A Stockholder's ability to use capital losses to offset ordinary income is
limited.

BACKUP WITHHOLDING

     Under the U.S. federal income tax backup withholding rules, unless an
exemption applies, we will be required to withhold 30% of all payments to which
you are entitled pursuant to the Offer, unless you provide a tax identification
number and certify under penalties of perjury, that the number is correct. If
you are an individual, the tax identification number is your social security
number. If you are not an individual, the tax identification number is your
employer identification number. You should complete and sign the Substitute Form
W-9, which will be included with the Transmittal Letter to be returned to the
Depositary, in order to provide the information and certification necessary to
avoid backup withholding, unless an applicable exception exists and is proved in
a manner satisfactory to the Depositary. Certain Stockholders, including
corporations and some foreign individuals, are not subject to these backup
withholding and reporting requirements.

     In order for a foreign individual to qualify as an exempt recipient,
however, he or she must submit, if eligible, a Certificate of Foreign Status on
Form W-8BEN attesting to his or her exempt status. Any amounts withheld will be
allowed as a credit against the holder's U.S. federal income tax liability for
that year.

     The foregoing U.S. federal income tax discussion may not be applicable with
respect to Shares received pursuant to the exercise of employee stock options or
otherwise as compensation or with respect to holders of Shares who are subject
to special tax treatment under the Internal Revenue Code, such as certain
non-U.S. Persons, life insurance companies, tax-exempt organizations and
financial institutions, and may not apply to a holder of Shares in light of
individual circumstances. The discussion is included for general information
only and is based upon laws, regulations, rulings and decisions now in effect,
all of which are subject to change, possibly retroactively. You are urged to
consult your own tax advisor with respect to the tax consequences of the Offer
and the Merger, including the application and effect of state, local, or foreign
income or other tax laws.

                  PRICE RANGE OF AND DIVIDENDS ON COMMON STOCK

     The Shares are not listed on a national securities exchange or quoted on an
inter-dealer quotation system. Thus, historical market or trading prices for the
Shares are not available.

     The Restated Certificate contains restrictions on the transferability of
Shares. The Restated Certificate also requires the Company, subject to the
conditions and limitations set forth in the Restated Certificate, to

                                        14


purchase Shares from holders who wish to sell them based upon a formula price.
The formula price is based, in large part, on the prior year-end book value of
the Company and remains fixed for the calendar year. According to the Company,
the formula price was $7.14 per Share in 2000 and $7.86 per Share in 2001, and
is $8.77 per Share in 2002. The 2002 per Share formula price will remain in
effect for the rest of 2002. See "Certain Information Concerning the
Company -- Selected Consolidated Financial Information."

     The Company has not in the past and does not intend in the future to pay
dividends on its Common Stock. Further, the Merger Agreement does not permit the
Company to pay any such dividends.

         EFFECT OF THE OFFER ON THE COMPANY'S EXCHANGE ACT REGISTRATION

     The Shares are currently registered under the Exchange Act. Registration of
the Shares under the Exchange Act may be terminated upon notice to the SEC if
the Shares are neither listed on a national securities exchange nor held by 300
or more holders of record. Termination of registration of the Shares under the
Exchange Act would substantially reduce the information required to be furnished
by the Company to its Stockholders and to the SEC and would make certain
provisions of the Exchange Act no longer applicable to the Company, such as the
short-swing profit recovery provisions of Section 16(b) of the Exchange Act, the
requirement of furnishing a proxy statement pursuant to Section 14(a) of the
Exchange Act in connection with Stockholders' meetings and the related
requirement of furnishing an annual report to Stockholders, and the requirements
of Rule 13e-3 under the Exchange Act with respect to "going private"
transactions. It is likely that we will file notice to terminate registration of
the Shares on behalf of the Company at the conclusion of the Offer if the
Minimum Condition is satisfied (although we may be subject to proxy rules until
effectiveness of the termination of registration) and if after the completion of
the Offer the Company has fewer than 300 Stockholders of record. If more than
300 Stockholders of record remain at the completion of the Offer and the Merger
is thereafter consummated, we will file notice to terminate such registration
upon the Effective Time of the Merger.

(1) Basic earnings per share were computed by the Company using the weighted
    average number of Shares outstanding during each period. Diluted earnings
    per Share gives effect to Debentures considered to be dilutive common stock
    equivalents. The potentially dilutive Debentures were calculated by the
    Company in accordance with the "if converted" method. This method assumes
    that the after-tax interest expense associated with the Debentures is an
    addition to income and the Debentures are converted into equity with the
    resulting Shares being aggregated with the weighted average Shares
    outstanding.

                                        16


(2) Pursuant to the Restated Certificate, the formula price calculation is
    computed annually at the end of the fiscal year. All Share repurchases by
    the Company commencing during the subsequent year are valued at the previous
    fiscal year end formula price. See "Price Range of and Dividends on Common
    Stock." Thus, stock repurchased during 2001 was at $7.86 per Share.

(3) Holders of Shares are prohibited from transferring the Shares in any manner
    except in a sale to the Company and to certain authorized transferees of the
    holders. The Company is generally required to purchase all Shares at the
    formula price. The aggregate redemption value of Shares at March 31, 2002,
    December 31, 2001 and December 31, 2000 was $316,464, $317,622 and $286,603,
    respectively. See "Price Range of and Dividends on Common Stock." A
    comparable figure at March 31, 2001 was not provided in the Company's
    Quarterly Report on Form 10-Q for the quarter ended March 31, 2002.

(4) This information is not in the Company's Quarterly Report on Form 10-Q for
    the quarter ended March 31, 2002, but was provided by the Company.

CERTAIN PROJECTIONS

     The Company provided us in its initial offering materials (dated January
2002) with summary projections of the Company that included the following:

<Table>
<Caption>
                                                                   2002
                                                               ------------
                                                            
Projected revenues..........................................   $510,574,000
Projected operating earnings................................   $ 52,853,000
Projected net earnings......................................   $ 34,526,000
</Table>

Separately, the Company provided us with projections of cash at the end of
September 2002 of $129,268,000 and at the end of October 2002 of $133,843,000
(together, the "Company's Projections"). The Company had also provided
projections for 2001, but those were superseded by the Company's actual
financial information as set forth above.

     The Company's Projections were used in our due diligence with respect to
the Company, but our offer to purchase was based on our extensive due diligence
with respect to the Company's operations. It is our view that while in general
the Company's Projections played a small part in making our decisions, the cash
projections at September 2002 and October 2002 were a factor, among others, in
our decision to proceed without a post-closing adjustment. See "Background of
the Offer."

     We have been advised by management of the Company that the Company's
Projections were produced by the Company's management, were not audited, and
were not prepared for publication or with a view to complying with the published
guidelines of the SEC regarding projections or with the American Institute of
Certified Public Accountants guide for Prospective Financial Statements. Such
information is being included in this Offer to Purchase solely because it was
furnished to us in connection with the discussions giving rise to the Merger
Agreement. The independent accountants of the Company have neither examined nor
compiled the financial information set forth above and, accordingly, do not
express an opinion or any other form of assurance with respect thereto.

     The Company's Projections, while they did not so state on their face,
necessarily reflect numerous assumptions with respect to general business and
economic conditions and other matters, many of which are inherently uncertain or
beyond the Company's or our control, may not be apparent on the face of the
Company's Projections and do not take into account any changes in the Company's
operations or capital structure which may result from the Offer and the Merger.
In addition, factors such as economic conditions in the markets served, levels
of construction spending in the markets served, transportation costs,
competition from existing or future competitors, our ability to integrate
acquisitions quickly and effectively, industry performance, regulatory and
financial conditions, and our ability to complete successfully the Offer, the
outcomes of each of which are difficult to project, may cause the Company's
Projections or the underlying

                                        17


assumptions to be inaccurate. It is not possible to predict whether the
assumptions made in preparing the projected financial information will be valid.
Accordingly, there can be no assurance that the Company's Projections will be
realized, and actual results may prove to be materially higher or lower than
those contained in the projections. The inclusion of this information should not
be regarded as an indication that we, the Company or anyone else who received
this information considered it a reliable predictor of future events, and this
information should not be relied on as such. None of us, the Company or any of
our respective representatives assumes any responsibility for the validity,
reasonableness, or completeness of the projected financial information, and the
Company has made no representation to us regarding such information.

AVAILABLE INFORMATION

Exchange Act and in accordance therewith is obligated to file reports and other

                     INTEREST IN SECURITIES OF THE COMPANY

     Neither Parent, Purchaser, nor any other associate, majority-owned
subsidiary or affiliate of Parent or Purchaser (each, a "Purchaser Entity" and
collectively, the "Purchaser Entities"), nor, to the knowledge of Parent or
Purchaser, any of the persons listed in Schedule I hereto or any associate

                                        20


                           SOURCE AND AMOUNT OF FUNDS

     The total amount of funds required to purchase all of the Shares pursuant
to the Offer to Purchase, to consummate the Merger and to pay fees and expenses
related to the Offer to Purchase and the Merger is estimated to be approximately
$650 million. Purchaser will obtain all funds needed for the Offer to Purchase
and the Merger from Parent.

     Parent currently anticipates obtaining such funds from standby credit
facilities that it maintains with various lenders in the aggregate amount of
$810 million, all of which is available for borrowing. One of the facilities has
been amended to provide a $100 million increase in the line for five business
days, which if borrowed must be repaid within five business days after such
funds are borrowed. The maturity dates of these facilities range from March 2003
to July 2006 and have interest rates ranging from LIBOR plus 0.25% to LIBOR plus
0.40% per year. Otherwise, the relevant terms of these credit facilities,
including affirmative and negative covenants, events of default and remedies in
the event of default, are substantively similar. As an illustrative example of
these credit facilities, we have filed a copy of one of them with the SEC as an
exhibit to the Tender Offer Statement on Schedule TO to which this Offer to
Purchase is an exhibit. Pursuant to the rules of the SEC, we have omitted the
name of the bank with which we have established this facility from the Schedule
TO.

     Borrowings under these facilities will be repaid by Parent in the ordinary
course of business, including by utilizing cash on hand of the Company at the
time the Merger is complete.

     The Offer is not contingent on Purchaser's or Parent's ability to obtain
financing for the Offer. Purchaser and Parent expressly reserve the right to
obtain financing for the Offer through alternative sources. However, currently
no alternative financing arrangements or alternative financing plans exist.

                                        21


                            BACKGROUND OF THE OFFER

     In early January 2002, David V. Clarke, the Chief Executive Officer of
Parent, was contacted by James Goodwin, a director of the Company and a
principal of James Goodwin Inc. and the Company's financial advisor, indicating
that the Company was conducting a process to solicit interest in a potential
sale of the Company and that Parent was being contacted as a potential bidder.

     On January 10, 2002, the Company and Parent signed a confidentiality
agreement. On January 15, 2002, Parent received the Company's Confidential
Memorandum which was provided to assist potential bidders to determine whether
to submit an indication of interest with regard to a potential acquisition of
the Company. On January 30, 2002, Parent submitted a non-binding indication of
interest, which indication was based solely on the Confidential Memorandum and
certain supplemental information provided by the Company as to potential
corporate overhead savings and in response to six questions posed by Parent, but
without the Parent's conducting due diligence.

     Thereafter, representatives of Parent attended presentations by Company
management and conducted a preliminary due diligence review of the Company. On
May 13, 2002, Parent submitted a bid to acquire the Company through a merger
(without a tender offer). The bid was based on certain assumptions as to cash
and was subject to a post-closing purchase price adjustment up or down based
upon the cash and working capital of the Company on the closing date and was
subject to a variety of conditions, including the completion of a number of due
diligence matters. The bid also contained an escrow of a portion of the purchase
price and an indemnity from the Stockholders for breaches of the Company's
representations and warranties in the merger agreement.

     On May 15, 2002, Peter W. Trimble, the Vice President -- Strategy &
Development of Parent, received a telephone call from Mr. Goodwin indicating
that the Company was interested in pursuing a transaction with Parent if Parent
would change the conditions in its bid relating to the escrow, the
indemnification and several other provisions. On May 16 and 17, 2002, Mr.
Clarke, Thomas G. Burmeister, Parent's Chief Financial Officer, Mr. Trimble,
Mike F. Egan, Parent's Vice President and General Counsel, and Thomas B. Hyman,
Jr. and Edward W. Kallal, Jr. of Sutherland Asbill & Brennan LLP ("Sutherland"),
Parent's legal counsel, met in New York with Mr. Goodwin, Donald E. Bowman, the
Company's Chief Financial Officer, Mark E. Belmont, the Company's General
Counsel, and David K. Boston and Stuart R. Goldfarb of Willkie Farr & Gallagher
("Willkie Farr"), legal counsel to the Company. The primary purpose of this
meeting was to discuss the terms and conditions of Parent's bid and to agree
upon the scope and timing of the remaining due diligence review of the Company
to be conducted by Parent.

     Following these meetings, the Company agreed on May 20, 2002 to deal
exclusively with Parent for a 30-day period regarding a sale of the Company, and
an exclusivity letter was signed on that date. Thereafter, the exclusivity
period was extended three times. On June 19, 2002, it was extended through June
21, 2002. After May 20, 2002, the parties continued to negotiate the terms of
the Merger Agreement and related documents, Parent conducted further due
diligence, and Parent's senior management had numerous telephone conversations
with the Company's management concerning the various agreement drafts and
various aspects of the Company and its business. On June 21, 2002,
representatives of Parent and Sutherland met with Mr. Goodwin and
representatives of Willkie Farr in New York to review the status of the
negotiations of the transaction, including the Merger Agreement and Parent's due
diligence of the Company. Mr. Bowman and Mr. Belmont participated in this
meeting via telephone. Following this meeting, the exclusivity letter was
extended through June 24, 2002 with Parent undertaking to consider a transaction
with a fixed per share purchase price and no post-closing working capital
adjustment. On June 24, 2002, the exclusivity period was extended again until
July 8, 2002.

     Following the meeting on June 21, 2002, the parties continued negotiations
and entered into the Merger Agreement on July 9, 2002, providing for a purchase
price of $17.00 per share, payable as provided in the Merger Agreement and as
described in this Offer to Purchase. See "Introduction."

                                        22


                      MERGER AGREEMENT AND RELATED MATTERS

     The following is a summary of certain provisions of the Merger Agreement.
This summary is qualified in its entirety by reference to the Merger Agreement
which is incorporated herein by reference and a copy of which has been filed
with the SEC as an exhibit to the Tender Offer Statement on Schedule TO to which
this Offer to Purchase is an exhibit (the "Schedule TO"). The Merger Agreement
may be examined and a copy of it may be obtained in the manner set forth in
"Certain Information Concerning the Company -- Available Information."

THE OFFER

     Under the Merger Agreement, we agreed to commence the Offer within ten
business days after July 9, 2002, the date on which the Offer was announced. We
also agreed that, upon the terms and subject to prior satisfaction or waiver of
certain conditions to the Offer (including, if the Offer is extended or amended,
the terms and conditions of any extension or amendment), we will accept for
payment, and pay for, all Shares validly tendered pursuant to the Offer and not
properly withdrawn on or prior to the Expiration Date, as it may be extended
from time to time. The conditions to the Offer are described in "Certain
Conditions to the Offer" and are referred to herein as the "Offer Conditions."

DESIGNATION OF DIRECTORS

     Subject to applicable law, promptly upon the purchase by us of any Shares
pursuant to the Offer, and from time to time thereafter as we acquire Shares,
Parent will have the right under the Merger Agreement to designate such number
of directors, rounded up to the next whole number, to serve on the Board of
Directors of the Company as will give Parent representation on the Board equal
to the product of (i) the total number of directors on the Board (giving effect
to any increases in the number of directors on the Board in accordance with the
terms of the Merger Agreement) and (ii) the percentage that the number of Shares
beneficially owned by Parent, Purchaser or any of their respective affiliates
bears to the number of Shares outstanding. However, prior to the completion of
the Merger, the Board shall always have at least one director who is neither an
officer of the Company nor is a designee, stockholder, affiliate or associate of
Parent (the "Independent Director"). The Company also agreed to cause
individuals designated by Parent to constitute the same percentage as is on the
entire Board to be on (i) each committee of the Board of Directors and (ii) each
board of directors and each committee thereof of each subsidiary of the Company.
The Merger Agreement provides that the Company will, upon Parent's request,
promptly take all actions necessary to cause Parent's designees to be validly
elected or appointed to the Board, including without limitation, increasing the
size of the Board or securing the resignations of such number of directors as is
necessary to provide us with such level of representation. The identity,
background and certain other information of the individuals Parent may designate
for appointment to the Board under this provision are included in the Schedule
14D-9.

THE MERGER

     The Merger Agreement provides that, after the completion of the Offer and
the satisfaction or waiver of certain conditions, Purchaser will be merged with
and into the Company, with the Company as the surviving corporation (the
"Surviving Corporation") in the Merger. Following the Merger, the Company will
be a wholly owned subsidiary of Parent. As a result of the Merger, Purchaser's
separate corporate existence will cease.

MERGER WITHOUT A MEETING OF STOCKHOLDERS

     The Merger Agreement provides that if Purchaser has not waived the Minimum
Condition and has purchased the Shares tendered in the Offer, the Company shall,
at Parent's request, take all necessary and appropriate action to cause the
Merger to become effective as soon as practicable after the consummation of the
Offer without a meeting of the Stockholders, in accordance with Section 253 of
the DGCL. In that event, if you have not tendered your Shares in the Offer, you
will be notified that the Merger has occurred and will be

                                        23


provided with information regarding how to receive an amount in cash equal to
the Offer Price, without interest, subject to reduction only for any applicable
backup withholding or stock transfer taxes required by law to be withheld from
payments to Stockholders (the "Merger Consideration"), or exercise your
appraisal rights under the DGCL. See "Appraisal Rights."

SPECIAL MEETING OF STOCKHOLDERS

     Unless the Merger is consummated in accordance with Section 253 of the DGCL
(as discussed above), the Company is obligated to convene in accordance with
applicable law a special meeting of its Stockholders promptly following the
consummation of the Offer for the purpose of approving the Merger Agreement and
related Merger (the "Special Meeting"). Approval of the Merger will not require
a Stockholder meeting and vote unless Purchaser agrees to waive the Minimum
Condition and complete the Offer, in which case Purchaser would own less than
90% of the fully diluted Shares. In this case, Purchaser would be unable to
consummate the Merger without a Stockholder vote in accordance with Section 253
of the DGCL. In connection with that Special Meeting, the Company will provide
to its Stockholders notice of the Special Meeting, a proxy statement and form of
proxy or information statement, as the case may be, and any schedules required
to be filed with the SEC in connection with the Special Meeting (collectively,
the "Proxy Statement"). Except as described below under "Termination," the Proxy
Statement will include the recommendation of the Board that Stockholders vote in
favor of approval and adoption of the Merger Agreement and the Merger. Parent
and Purchaser have each agreed that, at the Special Meeting, all of the Shares
acquired pursuant to the Offer or otherwise owned or acquired by Parent,
Purchaser or any of their affiliates will be voted in favor of the Merger.

CONVERSION OF SHARES

     At the Effective Time, each outstanding Share (other than (i) Shares (if
any) held in the treasury of the Company or owned by Parent, Purchaser or any
subsidiary of Parent or Purchaser, all of which will be canceled without any
exchange of consideration, or (ii) Shares owned by Stockholders who did not
approve the Merger and have properly exercised and perfected appraisal rights in
accordance with Section 262 of the DGCL) will, by virtue of the Merger and
without action by the holder thereof, be converted into the right to receive the
Merger Consideration upon surrender of the certificate representing such Share.

CONVERSION OF EXISTING DEBENTURES

     Under the Merger Agreement, the Company was required to notify promptly all
holders of its outstanding Debentures of the Company's redemption thereof as of
a date not less than 30 days after the date of the notice. The Company will
effect the redemption of the Debentures in accordance with the terms of the
applicable indenture under which such Debentures were issued. On July 15, 2002,
the trustee of the Debentures, at the Company's request, notified the holders of
the Debentures of the Company's election to redeem the Debentures and the
holders' right to convert the Debentures into Shares until August 19, 2002. If
Debentures are converted into Shares, a Stockholder may then tender such Shares
as described in the Offer to Purchase. See "Terms of the Offer -- Procedures for
Tendering Shares -- Special Procedures for Holders of Debentures."

CERTIFICATE OF INCORPORATION AND BYLAWS

     The Certificate of Incorporation and the Bylaws of Purchaser in effect
immediately prior to the Effective Time will be the Certificate of Incorporation
and Bylaws of the Surviving Corporation until amended in accordance with its
Certificate of Incorporation and Bylaws, and applicable law.

DIRECTORS AND OFFICERS

     Our directors immediately prior to the Effective Time will be the initial
directors of the Surviving Corporation, and the officers of the Company
immediately prior to the Effective Time will be the initial officers of the
Surviving Corporation, in each case until their successors are elected or
appointed.

NO SOLICITATION

     The Company has agreed to cease, and cause its representatives to cease,
any existing activities, discussions or negotiations with any parties (other
than Parent, Purchaser or any of their respective affiliates) conducted prior to
the date of the Merger Agreement with respect to any Takeover Proposal (as
defined below). In addition, the Company has agreed not to, and to not permit
any of its subsidiaries to:

     - solicit or initiate any inquiries regarding, or the submission of, any
       Takeover Proposal;

     - participate in any discussions or negotiations regarding, or furnish to
       any person any information with respect to, any Takeover Proposal; or

     - enter into any agreement with respect to, or approve, any Takeover
       Proposal.

     For these purposes, a "Takeover Proposal" means any proposal or offer from
a third party to acquire beneficial ownership of all or a material portion of
the assets of the Company or any of its material subsidiaries or 30% or more of
any class of equity securities of the Company or any of such subsidiaries
pursuant to a merger, consolidation or other business combination, sale of
shares of capital stock, sale of assets, tender offer, exchange offer or similar
transaction with respect to either the Company or any of such subsidiaries, with
a "material portion" of the assets of the Company or any material subsidiary to
be at least 30% of the book value of such entity's assets.

     Notwithstanding the foregoing, the Company and the Board of Directors may
take and disclose to the Stockholders a position with respect to a tender or
exchange offer by a third party pursuant to Rules 14d-9 and 14e-2 promulgated
under the Exchange Act, or make any disclosure to the Stockholders if, based on
advice from outside counsel, the Board of Directors determines in good faith
that failing to do so would be reasonably likely to violate its fiduciary duty
under the DGCL. Further, prior to the time of acceptance of Shares for payment
pursuant to the Offer, the Company may furnish information concerning its
business, properties or assets to any person or group, and may negotiate and
participate in discussions and negotiations with such person or group concerning
a Takeover Proposal if (i) such person or group has submitted an unsolicited
written Takeover Proposal which the Board of Directors believes in good faith is
reasonably likely to lead to a Superior Proposal (as defined below) and (ii) the
Board of Directors determines in good faith, based upon advice of outside
counsel, that failing to do so would be reasonably likely to violate the Board
of Directors' fiduciary duties to the Stockholders under the DGCL. The Company
has agreed to promptly notify Parent of the existence and material terms of any
proposal or inquiry received by the Company from a third party after the date of
the Merger Agreement with respect to any Takeover Proposal prior to furnishing
any non-public information to, entering into negotiations with, or accepting a
Superior Proposal from such third party. The Company has also agreed to use all
reasonable efforts to keep Parent informed of the status and details of any such
Superior Proposal. Under the Merger Agreement, a Superior Proposal means a bona
fide written Takeover Proposal by a third party, where (i) the Board of
Directors determines in good faith that such proposal is more favorable to the
Stockholders than the Offer and the Merger (based on advice of the Company's
independent financial advisor), (ii) financing, to the extent required, is then
committed for such proposal or in the good faith judgment of the Board of
Directors is reasonably likely to be obtained by such third party and (iii) in
the good faith reasonable judgment of the Board of Directors of the Company,
such proposal is reasonably likely to be consummated.

     Except as described below, the Company has agreed that neither the Board of
Directors nor any committee thereof will (i) withdraw or modify, or propose to
withdraw or modify, in a manner adverse to Parent or Purchaser, the approval or
recommendation by the Board of Directors or a committee thereof of the Merger
Agreement or the transactions contemplated thereby, (ii) approve or recommend,
or propose to approve or recommend, any Takeover Proposal, or (iii) enter into
any agreement with respect to any Takeover Proposal.

     The Board of Directors may, prior to the time of acceptance for payment of
Shares pursuant to the Offer, withdraw or modify its approval or recommendation
of the Merger Agreement or the transactions contemplated thereby, approve or
recommend a Superior Proposal, or enter into an agreement with respect to a
Superior Proposal, only if (i) the Company shall have received a Superior
Proposal and (ii) the Board of

                                        28


Directors determines in good faith, based upon advice of outside counsel, that
the failure to take such action would be reasonably likely to violate the
Board's fiduciary duties to the Stockholders under the DGCL.

DIRECTORS' AND OFFICERS' INDEMNIFICATION AND INSURANCE

     The Merger Agreement requires that Parent shall cause the Surviving
Corporation to honor all rights to indemnification existing in favor of the
present or former directors, officers, employees or agents of the Company and
its subsidiaries and persons serving in like capacities for another corporation
or entity at the request of the Company (collectively, the "Indemnified
Parties") arising out of or pertaining to any act or omission of any Indemnified
Party occurring at or prior to the Effective Time, including, without
limitation, the transactions contemplated by the Merger Agreement, as such
indemnification rights are provided in the Restated Certificate or Bylaws of the
Company or any of its subsidiaries in effect as of the date of the Merger
Agreement. These obligations shall continue for six years after the Effective
Time. Further, the Surviving Corporation shall pay the reasonable fees and
expenses of counsel selected by the Indemnified Parties.

     The Company has obtained, or it will obtain prior to the Effective Time, an
extension of coverage for its existing directors' and officers' liability
insurance policy and certain other insurance policies described in the Merger
Agreement in an amount not less than the coverage that was in place as of the
date of the Merger Agreement. The Surviving Corporation shall not terminate or
modify this coverage, and neither Parent nor the Surviving Corporation shall
have any obligation to purchase any additional insurance with respect to the
Indemnified Parties or to make any payments with respect to this coverage. The
Surviving Corporation shall not have any obligation to provide indemnification
as described above unless (i) the carrier of these insurance policies has denied
coverage of the claim (or any portion thereof) for which indemnification is
being sought and the claimant has cooperated with the reasonable requests of the
Surviving Corporation regarding such policies, or (ii) the coverage under such
policies has been exhausted.

     In the event the Surviving Corporation consolidates with or merges into or
otherwise transfers all or substantially all of its assets, proper provision
will be made so that the successor assumes the foregoing obligations.

EMPLOYEE MATTERS

     The Merger Agreement requires the Surviving Corporation and its
subsidiaries to comply with the terms of all existing written employment,
severance, consulting and salary continuation agreements between the Company or
any subsidiary and any current or former officer, director, employee or
consultant of the Company or any subsidiary or group of such officers,
directors, employees or consultants. To the extent permitted under any
applicable law, each employee of the Company or any subsidiary shall be given
credit under the following employee benefit plans maintained by Parent in which
they become participants as employees of the Surviving Corporation or any
subsidiary for all service currently credited by the Company or such subsidiary
under comparable plans of the Company or any subsidiary: (i) under Parent's
401(k) plans, for purposes of eligibility to participate and vesting; (ii) under
Parent's severance policy, for purposes of eligibility to participate and the
calculation of the amount of the severance payment; and under the Company's
severance policy, such calculation is currently made on the basis of one week of
severance pay for each full year of service (but limited in all events to 26
weeks of severance pay); and (iii) under Parent's paid time off policy, for
purposes of eligibility to participate and of the calculation of the amount to
be accrued. If any such employee participates in any of Parent's defined benefit
pension plans (which is not expected to occur), no service credit will be
granted.

                                        29

or otherwise prohibiting the transactions contemplated by the Merger Agreement.

     - Parent or Purchaser shall have breached in any material respect any of
       its representations, warranties, covenants or other agreements contained
       in the Merger Agreement, which breach or failure to perform has not been

       Company; or

     - the Offer shall not have expired or been terminated on or before November
       8, 2002; provided that the Company may not terminate the Merger Agreement
       for this reason if the Company is in material breach of the Merger

     - the Company shall have breached in any material respect any of its
       covenants or other agreements contained in the Merger Agreement, which

        (as defined in "-- Termination -- Certain Material Adverse Effects"

       Agreement for this reason if Parent or Purchaser is in material breach of
       the Merger Agreement.

     Certain Material Adverse Effects.  If there has occurred any event, or the
disclosure of any act, omission, fact or circumstance, that individually or when
considered together with any other matter, may have a Material Adverse Effect,
and the Company has a claim for an insurance recovery for any such occurrence,
which, if paid (or if the carrier accepts coverage for such claim), would result
in there being no Material Adverse Effect:

     - Neither Parent nor Purchaser will have the right to terminate the Merger
       Agreement pursuant to the provisions of the second, third, fourth or
       fifth bullet points under "-- Termination -- By Parent or Purchaser"
       above based in whole or in part upon any such occurrence, and such
       occurrence will not be deemed for the purpose of the Merger Agreement
       (including with respect to the Offer Conditions) to constitute a Material
       Adverse Effect, until the carrier of any applicable insurance has
       provided a final written notice to the Company of whether coverage of any
       such claim or any portion thereof for which a recovery is being sought
       will be unconditionally accepted or denied (an "Insurance Recovery
       Notice");

     - the Expiration Date, and all references in the Merger Agreement (and in
       this Offer to Purchase) to the date "November 8, 2002," will be deemed to
       be extended to the date that is ten business days after the date on which
       such Insurance Recovery Notice is obtained, but in no event shall such
       date be extended beyond December 8, 2002; and

     - pending the receipt of any Insurance Recovery Notice, the parties shall
       comply with the terms of the Merger Agreement.

     Under the Merger Agreement, a "Material Adverse Effect" means any act,
omission, fact or circumstance that (i) results in or would reasonably be
expected to result in (A) the incurrence or increase of an obligation or
liability of the Company or any of its subsidiaries, (B) the diminution in value
of any of the assets or rights of the Company or any of its subsidiaries, or (C)
the effective loss by the Company or any of its subsidiaries of its rights to
use any of the assets of the Company and its subsidiaries as such assets are
presently used, and (ii) that exceeds, in any such case, individually or in the
aggregate, $32,400,000 (after giving effect to any applicable insurance coverage
if the Company or its subsidiaries has either received proceeds from such
coverage or, subject to the provisions summarized above, a written notice from
any insurer unconditionally accepting coverage or a portion thereof; provided,
however, that (x) any such acts, omissions, facts or circumstances directly
resulting from the Merger Agreement or the transactions contemplated by the
Merger Agreement or the announcement thereof, (y) any occurrence or condition
affecting the aggregates industry generally, or (z) any changes in general
economic, regulatory or political conditions, shall not constitute a Material
Adverse Effect or be included in any calculation thereof.

FEES AND EXPENSES

     Except as provided in "Termination Fee" below, whether or not the Merger is
consummated, all fees, costs and expenses incurred in connection with the Merger
Agreement and the transactions contemplated thereby will be paid by the party
incurring such fees, costs and expenses.

                                        31


TERMINATION FEE

     The Merger Agreement provides that, following a termination thereof by
Parent or Purchaser as described in the first bullet point under
"-- Termination -- By Parent or Purchaser" above or a termination thereof by the
Company as described in the first bullet point under "-- Termination -- By the
Company" above, the Company will pay Parent a termination fee (the "Termination
Fee") equal to $22,700,000 plus an amount equal to Parent's and Purchaser's
actual and reasonably documented out-of-pocket expenses (but in no event
exceeding a total of $2,000,000) incurred by Parent or Purchaser directly in
connection with the Offer, the Merger, the Merger Agreement, and the
transactions contemplated thereby. Such payment will be the exclusive remedy of
Parent and Purchaser with respect to any such termination of the Merger
Agreement.

AMENDMENT

     The Merger Agreement may be amended at any time before the Effective Time
by action taken by Parent, Purchaser and the Company, by written instrument
signed by the parties to the Merger Agreement. After any approval of the Merger
by the Stockholders, no amendment may be made which reduces the amount or
changes the type of consideration into which each Share will be converted upon
consummation of the Merger. Notwithstanding anything to the contrary, following
the time that directors designated by Parent constitute a majority of the Board
of Directors, the affirmative vote of a majority of the Independent Directors
shall be required for the Company to amend, modify or terminate the Merger
Agreement.

UNDERTAKINGS OF PARENT

     Parent has agreed to perform, or cause to be performed, all obligations of
Purchaser under the Merger Agreement.

                                        32


                 PURPOSE OF THE OFFER AND PLANS FOR THE COMPANY

PURPOSE

     The purpose of the Offer and the Merger is for Parent to acquire control
of, and ultimately the entire equity interest in, the Company. The Offer, as the
first step in the acquisition of the Company, is intended to facilitate
Purchaser's acquisition of all the Shares. The purpose of the Merger is to
acquire all Shares not purchased in the Offer or otherwise. Pursuant to the
Merger, each then outstanding Share (other than Shares (i) owned by Purchaser or
Parent or any of their subsidiaries, (ii) owned by the Company in treasury, or
(iii) as to which appraisal rights are properly exercised) will be converted
into the right to receive an amount in cash equal to the per Share consideration
paid or to be paid in the Offer. Upon consummation of the Merger, the Company
will become a wholly owned subsidiary of Parent.

APPROVAL OF MERGER AGREEMENT

     Except as described below, under Delaware law, the approval of the Board
and the affirmative vote of the holders of a majority of the outstanding Shares
is required to approve and adopt the Merger Agreement and the transactions
contemplated thereby, including the Offer and the Merger. The Board has
unanimously determined that the Merger Agreement and the related transactions,
including the Offer and the Merger, are fair to, and in the best interests of,
the Stockholders, has approved, adopted and declared advisable the Merger
Agreement and the related transactions, including the Offer and the Merger (such
approval and adoption having been made in accordance with the DGCL), and has
resolved to recommend that the Stockholders accept the Offer and tender their
Shares pursuant to the Offer, and approve and adopt the Merger Agreement and the
transactions contemplated thereby, including the Merger. Further, the Company
has agreed to use all reasonable efforts to solicit from Stockholders proxies in
favor of the Merger and to take all other action necessary, or in the reasonable
opinion of Parent, advisable, to secure any vote or consent of Stockholders in
favor of the Merger, if such Stockholder approval is necessary to effect the
Merger. Assuming that the Minimum Condition is satisfied and the Merger is
consummated pursuant to the short-form merger provisions under Section 253 of
the DGCL, no further corporate or Stockholder action of the Company will be
required to approve and adopt the Merger Agreement and the Merger. See
"-- Short-Form Merger." If the Minimum Condition is waived by Purchaser but the
Offer is consummated, and Purchaser owns less than 90% of the Shares, the
Company has agreed to convene a special meeting of Stockholders promptly
following consummation of the Offer for the purpose of considering and taking
action on the Merger Agreement and the transactions contemplated thereby,
including the Offer and the Merger.

ELECTION OF DIRECTORS

     The Merger Agreement provides that, promptly upon the purchase by Purchaser
of Shares pursuant to the Offer, Purchaser will be entitled to designate
representatives to serve on the Board in proportion to Purchaser's ownership of
Shares following such purchase. See "Merger Agreement and Related Matters --
Designation of Directors." Purchaser expects that such representation would
permit Purchaser to exert substantial influence over the Company's conduct of
its business and operations.

EXCHANGE ACT REGISTRATION

     The Shares are currently registered under the Exchange Act. Such
registration may be terminated upon application by the Company to the SEC if the
Shares are not listed on a "national securities exchange" and there are fewer
than 300 record holders. If registration of the Shares under the Exchange Act
were terminated, the Company would no longer be required to file reports with
the SEC, and many provisions of the Exchange Act would cease to apply to the
Company and its executive officers, directors and significant shareholders. We
currently intend to seek to cause the Company to terminate the registration of
the Shares under the Exchange Act as soon after consummation of the Offer as the
requirements for termination of registration are met. See "Effect of the Offer
on the Company's Exchange Act Registration."

                                        33


SHORT-FORM MERGER

     Under Delaware law, if we acquire, pursuant to the Offer or otherwise, at
least 90% of the then outstanding Shares, we will be able to approve the Merger
without a vote of the Stockholders (a "Short-Form Merger"). In such event, the
parties to the Merger Agreement will take all necessary and appropriate action
to cause the Merger to become effective as promptly as reasonably practicable
after such acquisition, without a meeting of the Stockholders. If, however, we
do not acquire at least 90% of the outstanding Shares pursuant to the Offer or
otherwise and a vote of the Stockholders is required under the DGCL, a
significantly longer period of time would be required to effect the Merger.

GOING PRIVATE TRANSACTIONS

     The SEC has adopted Rule 13e-3 under the Exchange Act which is applicable
to certain "going private" transactions and which may under certain
circumstances be applicable to a merger or another business combination
following the purchase of shares pursuant to a tender offer in which the
purchaser seeks to acquire the remaining shares not held by it or its
affiliates. We believe that neither the Offer nor the Merger will be subject to
Rule 13e-3. Rule 13e-3 requires, among other things, that certain financial
information concerning the Company and certain information relating to the
fairness of the proposed transaction and the consideration offered to minority
stockholders in such transaction be filed with the SEC and disclosed to
stockholders prior to consummation of the transaction.

PURCHASE OF SHARES AFTER THE EXPIRATION DATE

     If the Offer is completed, we intend to purchase the remaining Shares, if
any, through the Merger. If the Offer is not completed, while Parent, Purchaser
or an affiliate of Parent may after the Expiration Date seek to acquire Shares
through privately negotiated transactions, a tender offer or exchange offer or
otherwise, upon such terms and at such prices as they shall determine, which may
be more or less than the price paid in the Offer, they currently do not intend
to do so.

PLANS FOR THE COMPANY'S BUSINESS

     In connection with the Offer, we have reviewed, and will continue to
review, on the basis of available information, various possible business
strategies that the Company may pursue in the event that we acquire control of
the Company pursuant to this Offer or the Merger. If we acquire control of the
Company, we intend to conduct a further review of the Company and its assets,
corporate structure, dividend policy, capitalization, operations, properties,
policies, management and personnel and consider and determine what, if any,
changes would be desirable in light of the circumstances which then exist. Such
strategies could include, among other things, changes in the Company's business
strategy, corporate structure, certificate of incorporation, bylaws,
capitalization, management or dividend policy.

                                APPRAISAL RIGHTS

GENERAL

     No appraisal rights are available in connection with the Offer. However, if
the Merger is consummated, any holder of Shares at the Effective Time (a
"Remaining Stockholder") will have certain rights under the DGCL to dissent and
demand appraisal of his or her Shares. Under Section 262 of the DGCL, a
Remaining Stockholder who does not wish to accept the Merger Consideration for
its Shares pursuant to the Merger has the right to seek an appraisal and be paid
the "fair value" of his or her Shares at the Effective Time (exclusive of any
element of value arising from the accomplishment or expectation of the Merger)
judicially determined and paid in cash, provided that such holder complies with
the provisions of Section 262 of the DGCL.

     The following is a brief summary of the statutory procedures to be followed
by a Remaining Stockholder in order to dissent from the Merger and perfect
appraisal rights under Delaware law. This summary is not intended to be complete
and is qualified in its entirety by reference to Section 262 of the DGCL, the
text of

                                        34


which is set forth in Annex A hereto. Any Remaining Stockholder considering
demanding appraisal is advised to consult legal counsel. Dissenters' rights will
not be available unless and until the Merger (or a similar business combination)
is consummated.

     Remaining Stockholders of record who desire to exercise their appraisal
rights must fully satisfy all of the following conditions. A written demand for
appraisal of Shares must be delivered to the Secretary of the Company (1) before
the taking of the vote on the approval and adoption of the Merger Agreement if
the Merger is not being effected as a Short-Form Merger but rather is being
consummated following approval thereof at a meeting of the Stockholders (a
"Long-Form Merger") or (2) within 20 days after the date that the Surviving
Corporation mails to the Remaining Stockholders a notice (the "Notice of
Merger") to the effect that the Merger is effective and that appraisal rights
are available (and includes in such notice a copy of Section 262 of the DGCL and
any other information required thereby) if the Merger is being effected as a
Short-Form Merger without a vote or meeting of the Stockholders. If the Merger
is effected as a Long-Form Merger, this written demand for appraisal of Shares
must be in addition to, and separate from, any proxy or vote abstaining from or
against the approval of the Merger, and neither voting against, abstaining from
voting, nor failing to vote on the Merger will constitute a demand for appraisal
within the meaning of Section 262 of the DGCL. In the case of a Long-Form
Merger, any Stockholder seeking appraisal rights must hold the Shares for which
appraisal is sought on the date of the making of the demand, continuously hold
such Shares through the Effective Time, and otherwise comply with the provisions
of Section 262 of the DGCL.

     In the case of both a Short-Form Merger and a Long-Form Merger, a demand
for appraisal must be executed by or for the Stockholder of record, fully and
correctly, as such Stockholder's name appears on the stock certificates. If the
Shares are owned of record in a fiduciary capacity, such as by a trustee,
guardian or custodian, such demand must be executed by the fiduciary. If Shares
are owned of record by more than one person, as in a joint tenancy or tenancy in
common, such demand must be executed by all joint owners. An authorized agent,
including an agent for two or more joint owners, may execute the demand for
appraisal for a Stockholder of record; however, the agent must identify the
record owner and expressly disclose the fact that, in exercising the demand, he
is acting as agent for the record owner.

     The Remaining Stockholders who elect to exercise appraisal rights must mail
or deliver their written demands to: Secretary of the Surviving Corporation,
1501 Belvedere Road, West Palm Beach, Florida 33406. The written demand for
appraisal should specify the Stockholder's name and mailing address, the number
of Shares covered by the demand and that the Stockholder intends to thereby
demand appraisal of such Shares. In the case of a Long-Form Merger, the Company
must, within ten days after the Effective Time, provide notice of the Effective
Time to all Stockholders who have complied with Section 262 of the DGCL and have
not voted for approval and adoption of the Merger Agreement.

     In the case of a Long-Form Merger, the Remaining Stockholders electing to
exercise their appraisal rights under Section 262 must not vote for the approval
of the Merger or consent thereto in writing. Voting in favor of the approval of
the Merger, or delivering a proxy in connection with the Stockholders meeting
called to approve the Merger (unless the proxy votes against, or expressly
abstains from the vote on, the approval and adoption of the Merger), will
constitute a waiver of the Remaining Stockholder's right of appraisal and will
nullify any written demand for appraisal submitted by the Remaining Stockholder.

     Regardless of whether the Merger is effected as a Long-Form Merger or a
Short-Form Merger, within 120 days after the Effective Time, either the Company
or any Stockholder who has complied with the required conditions of Section 262
and who is otherwise entitled to appraisal rights may file a petition in the
Delaware Court of Chancery demanding a determination of the fair value of the
Shares of the dissenting Stockholders. If a petition for an appraisal is timely
filed, after a hearing on such petition, the Delaware Court of Chancery will
determine which Stockholders are entitled to appraisal rights and thereafter
will appraise the Shares owned by such Stockholders, determining the fair value
of such Shares, exclusive of any element of value arising from the
accomplishment or expectation of the Merger, together with a fair rate of
interest to be paid, if any, upon the amount determined to be the fair value.

     In determining fair value, the Delaware Court of Chancery is to take into
account all relevant factors. In Weinberger v. UOP, Inc., the Delaware Supreme
Court discussed the factors that could be considered in

                                        35


determining fair value in an appraisal proceeding, stating that "proof of value
by any techniques or methods which are generally considered acceptable in the
financial community and otherwise admissible in court" should be considered and
that "[f]air price obviously requires consideration of all relevant factors
involving the value of a Company." The Delaware Supreme Court stated that in
making this determination of fair value the court must consider "market value,
asset value, dividends, earnings prospects, the nature of the enterprise and any
other facts which were known or which could be ascertained as of the date of
Merger which throw any light on future prospects of the merged corporation." The
Delaware Supreme Court has construed Section 262 of the DGCL to mean that
"elements of future value, including the nature of the enterprise, which are
known or susceptible of proof as of the date of the Merger and not the product
of speculation, may be considered." However, the Court noted that Section 262
provides that fair value is to be determined "exclusive of any element of value
arising from the accomplishment or expectation of the Merger."

     Remaining Stockholders who in the future consider seeking appraisal should
have in mind that the fair value of their Shares determined under Section 262
could be more than, the same as, or less than the Merger Consideration if they
do seek appraisal of their Shares. The cost of the appraisal proceeding may be
determined by the Delaware Court of Chancery and taxed upon the parties, as the
Delaware Court of Chancery deems equitable in the circumstances. Upon
application of a dissenting Stockholder, the Delaware Court of Chancery may
order that all or a portion of the expenses incurred by any dissenting
Stockholder in connection with the appraisal proceeding, including, without
limitation, reasonable attorneys' fees and the fees and expenses of experts, be
charged pro rata against the value of all Shares entitled to appraisal. In the
absence of such a determination or assessment, each party bears its own
expenses.

     Any Remaining Stockholder who has duly demanded appraisal in compliance
with Section 262 of the DGCL will not, after the Effective Time, be entitled to
vote for any purpose the Shares subject to such demand or to receive payment of
dividends or other distributions on such Shares, except for dividends or other
distributions payable to Stockholders of record at a date prior to the Effective
Time.

     At any time within 60 days after the Effective Time, any former holder of
Shares shall have the right to withdraw his or her demand for appraisal and to
accept the Merger Consideration paid in the Merger. After this period, such
holder may withdraw his or her demand for appraisal only with the consent of the
Company, as the Surviving Corporation in the Merger. If no petition for
appraisal is filed with the Delaware Court of Chancery within 120 days after the
Effective Time, Remaining Stockholders' rights to appraisal shall cease and all
Remaining Stockholders shall be entitled to receive the Merger Consideration for
their Shares. Inasmuch as the Company has no obligation to file such a petition,
and Parent has no present intention to cause or permit the Surviving Corporation
in the Merger to do so, any Stockholder who desires such a petition to be filed
is advised to file it on a timely basis. However, no petition timely filed in
the Delaware Court of Chancery demanding appraisal shall be dismissed as to any
Stockholder without the approval of the Delaware Court of Chancery, and such
approval may be conditioned upon such terms as the Delaware Court of Chancery
deems just.

     Failure to take any required step in connection with the exercise of
appraisal rights may result in the termination or waiver of such rights.

APPRAISAL RIGHTS CANNOT BE EXERCISED AT THIS TIME. THE INFORMATION SET FORTH
ABOVE IS FOR INFORMATIONAL PURPOSES ONLY WITH RESPECT TO ALTERNATIVES AVAILABLE
TO STOCKHOLDERS IF THE MERGER IS CONSUMMATED. STOCKHOLDERS WHO WILL BE ENTITLED
TO APPRAISAL RIGHTS IN CONNECTION WITH THE MERGER WILL RECEIVE ADDITIONAL
INFORMATION CONCERNING APPRAISAL RIGHTS AND THE PROCEDURES TO BE FOLLOWED IN
CONNECTION THEREWITH BEFORE SUCH STOCKHOLDERS HAVE TO TAKE ANY ACTION RELATING
THERETO.

STOCKHOLDERS WHO SELL SHARES IN THE OFFER WILL NOT BE ENTITLED TO EXERCISE
APPRAISAL RIGHTS WITH RESPECT THERETO BUT, RATHER, WILL RECEIVE THE OFFER PRICE
PAID IN THE OFFER THEREFOR.

                          CERTAIN CAPITAL TRANSACTIONS

     The Merger Agreement does not permit the Company to (a) split, combine or
otherwise change the Shares or its capitalization, (b) acquire or otherwise
cause a reduction in the number of outstanding Shares or other securities (other
than as required by the Restated Certificate or existing agreements related to
any of the Debentures) or (c) issue or sell additional Shares, shares of any
other class of capital stock, other voting securities or any securities
convertible into, or exchangeable or exercisable for any of the foregoing, or
rights, warrants or options, conditional or otherwise, to acquire, any of the
foregoing, other than upon conversion of the Debentures.

                        CERTAIN CONDITIONS OF THE OFFER

     Notwithstanding any other provision of the Offer, Purchaser shall not be
required to accept for payment or, subject to any applicable rules and
regulations of the SEC, pay for, and (subject to any such rules or regulations)
may delay the acceptance for payment of any tendered Shares and (except as
provided in the Merger Agreement) amend or terminate the Offer as to any Shares
not then paid for if:

          (i) there shall not have been validly tendered and not withdrawn prior
     to the expiration of the Offer a number of shares of the Company's Common

          (ii) any applicable waiting period under the Hart-Scott-Rodino
     Antitrust Improvements Act of 1976, as amended (the "HSR Act"), shall not
     have expired or been terminated prior to the expiration of the Offer; or

          (iii) at any time after the date of the Merger Agreement and before
     the time of acceptance for payment of such Shares, any of the following
     events shall occur and be continuing or conditions exist:

             (a) there shall be an injunction or other order, decree, judgment
        or ruling issued, initiated or threatened and not withdrawn by a
        governmental entity of competent jurisdiction or a statute, rule,
        regulation, executive order or other action shall have been enacted,
        promulgated or taken or initiated or threatened and not withdrawn by a
        governmental entity of competent jurisdiction which in any such case (w)
        restrains or prohibits or seeks to restrain or prohibit the making or
        consummation of the Offer or the consummation of the Merger, (x)
        prohibits or restricts or seeks to prohibit or restrict the ownership or

        Parent (or any of its affiliates or subsidiaries) to dispose of or hold
        separate any portion of its or the Company's or any subsidiary's
        business or assets which is material to the business of all such
        entities taken as a whole, (y) imposes or seeks to impose limitations on
        the ability of Parent effectively to acquire or to hold or to exercise

        affiliates or subsidiaries effectively to control in any material
        respect the business and operations of the Company and its subsidiaries;
        provided, however, that in the case of any such proceeding that has been
        initiated or threatened, such proceeding shall be reasonably likely to
        have one of the foregoing effects;

             (b) the Merger Agreement shall have been terminated by the Company
        or Parent in accordance with its terms;

             (c) from and after the date of the Merger Agreement, there shall

        the forms, reports and documents the Company is or has been required to
        file with the SEC since September 30, 2000, that, individually or when
        considered together with any other matter, has a Material Adverse Effect
        (with any liability or obligation associated with any such previously
        undisclosed act, omission, fact or circumstance being deemed, for
        purposes of determin-

                                        37


        ing whether a Material Adverse Effect has occurred, to have been

        banking moratorium or any suspension of payments in respect of banks in
        the United States by any governmental entity, (y) any material

        Agreement;

             (e) any of the representations and warranties of the Company set
        forth in the Merger Agreement regarding its capitalization shall not be
        accurate in all respects, in each case as if such representations and
        warranties were remade at and as of the time of such determination;

             (f) any of the representations and warranties of the Company set
        forth in the Merger Agreement (other than those described in clause (e)
        above) (without regard to any materiality qualifications therein) shall
        not be accurate, except where such inaccuracies (considered
        collectively) do not have a Material Adverse Effect (determined in the
        manner provided in clause (c) above), in each case as if such
        representations and warranties were remade at and as of the time of such
        determination;

             (g) the Company shall have failed to perform in any respect any
        obligation, agreement or covenant of the Company described in clauses
        (a) through (l) under "Merger Agreement and Related
        Matters -- Covenants";

             (h) the Company shall have failed to perform in any material
        respect any material obligation (including, without limitation, the
        obligation to conduct the business of the Company and its subsidiaries
        in the ordinary course in a manner consistent with past practice but
        excluding those obligations described in clauses (a) through (l) under
        "Merger Agreement and Related Matters -- Covenants") or to comply in any
        material respect with any material agreement or covenant of the Company
        to be performed or complied with by it under the Merger Agreement;

             (i) the Board of Directors (w) shall have withdrawn, modified or
        changed in a manner adverse to Parent or Purchaser its approval or
        recommendation of the Merger Agreement or the transactions contemplated
        thereby, including the Offer and the Merger, (x) recommended a Takeover
        Proposal, (y) shall have adopted any resolution to effect any of the
        foregoing, or (z) waived the transfer restrictions in the Restated
        Certificate to enable a third party to acquire more than 15% of the
        outstanding Shares;

             (j) all authorizations, consents and approvals, if any, of any
        governmental entity necessary for the execution, delivery and
        performance of the Merger Agreement, of which the failure to obtain
        would prevent or materially impair or delay consummation of the
        transactions contemplated thereby or have a Material Adverse Effect,
        shall not have been obtained or be in full force and effect;

             (k) Parent shall not have received any of the documents to be
        delivered to Parent pursuant to Section 6.7(e) of the Merger Agreement,
        including tax opinions, certificates and acknowledgements; or

             (l) certain other transactions and deliveries required pursuant to
        an agreement with respect to the Company's Columbia, Washington sawmill
        property have not been consummated or delivered;

which in the reasonable judgment of Parent with respect to each and every matter
referred to above and regardless of the circumstances giving rise to any such
condition, makes it inadvisable to proceed with the Offer or with such
acceptance for payment of or payment for Shares.

                                        38


     The foregoing conditions are for the sole benefit of Parent and may be
asserted by Purchaser regardless of the circumstances giving rise to any such
conditions and may be waived by Purchaser in whole or in part at any time and
from time to time, in each case, in the exercise of the good faith judgment of
Purchaser and subject to the terms of the Merger Agreement. The failure by
Purchaser at any time to exercise any of the foregoing rights shall not be
deemed a waiver of any such right and each such right shall be deemed an ongoing
right which may be asserted at any time and from time to time.

                             CERTAIN LEGAL MATTERS

GENERAL

     Except as otherwise disclosed herein, and except for governmental approvals
pursuant to filings in compliance with the HSR Act, neither Parent nor Purchaser
is aware of any approval or other action by any governmental entity that would
be required for the acquisition or ownership of Shares as contemplated herein.
Should any such approval or other action be required, we currently contemplate
that such approval or action would be sought. While we do not currently intend
to delay the acceptance for payment of Shares tendered pursuant to the Offer
pending the outcome of any such matter, there can be no assurance that any such
approval or action, if needed, would be obtained or would be obtained without
substantial conditions or that adverse consequences might not result to the
business of the Company, Purchaser or Parent or that certain parts of the
businesses of the Company, Purchaser or Parent might not have to be disposed of
in the event that such approvals were not obtained or any other actions were not
taken. Our obligation under the Offer to accept for payment and pay for Shares
is subject to certain conditions. See "Certain Conditions of the Offer."

BUSINESS COMBINATION TRANSACTIONS

     The Company is incorporated under the laws of the State of Delaware. In
general, Section 203 of the DGCL prevents an "interested stockholder"
(generally, a person who owns or has the right to acquire 15% or more of a
corporation's outstanding voting stock, or an affiliate or associate thereof)
from engaging in a "business combination" (defined to include mergers and
certain other transactions) with a Delaware corporation for a period of five
years following the date such person becomes an interested stockholder unless
prior to such date the Board of Directors of the corporation approved the
business combination. The Board has approved (by a unanimous vote of those
directors present) both the Offer and the Merger. For this and other reasons,
Section 203 is inapplicable to the Merger Agreement and the transactions
contemplated thereby, including the Offer and the Merger.

OTHER STATE LAWS

     A number of other states have adopted laws and regulations applicable to
attempts to acquire securities of corporations which are incorporated, or have
substantial assets, stockholders, principal executive offices or principal
places of business, or whose business operations otherwise have substantial
economic effects, in such states. In 1982, in Edgar v. Mite Corp., the Supreme
Court of the United States invalidated on constitutional grounds the Illinois
Business Takeover Statute, which, as a matter of state securities law, made
takeovers of corporations meeting certain requirements more difficult. However,
in 1987 in CTS Corporation v. Dynamics Corp. of America, the Supreme Court held
that the Indiana Control Share Acquisition Act was constitutional. Such Act, by
its terms, is applicable only to corporations that have a substantial number of
stockholders in Indiana and are incorporated there. Subsequently, a number of
federal courts ruled that various state takeover statutes were unconstitutional
insofar as they apply to corporations incorporated outside the state of
enactment. The Company, directly or through subsidiaries, conducts business in a
number of states throughout the United States, some of which have enacted
takeover laws. We do not believe that, other than Section 203 of the DGCL, any
state takeover statutes or similar laws purport to apply to the Offer or the
Merger. We have not currently complied with any other state takeover statute or
regulation. Should any person seek to apply any state takeover law, we will take
such action as then appears desirable, which may include challenging the
validity or applicability of any such statute in appropriate court proceedings.
In the event it is asserted that one or more state takeover laws is applicable
to the Offer and the Merger, and an

                                        39


appropriate court does not determine that it is inapplicable or invalid as
applied to the Offer, we might be required to file certain information with, or
receive approvals from, the relevant state authorities. In addition, if
enjoined, we might be unable to accept for payment any Shares tendered pursuant
to the Offer, or be delayed in continuing or consummating the Offer. In such
case, we may not be obligated to accept for payment any Shares tendered. See
"Certain Conditions of the Offer."

     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of sec. 251 of this title.

          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     sec.sec. 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:

             a.  Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;

             b.  Shares of stock of any other corporation, or depository
        receipts in respect thereof, which shares of stock (or depository
        receipts in respect thereof) or depository receipts at the effective
        date of the merger or consolidation will be either listed on a national
        securities exchange or designated as a national market system security
        on an interdealer quotation system by the National Association of
        Securities Dealers, Inc. or held of record by more than 2,000 holders;

             c.  Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or

             d.  Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.

                                       A-1


          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec. 253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.

     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d) Appraisal rights shall be perfected as follows:

          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsection (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of such
     stockholder's shares shall deliver to the corporation, before the taking of
     the vote on the merger or consolidation, a written demand for appraisal of
     such stockholder's shares. Such demand will be sufficient if it reasonably
     informs the corporation of the identity of the stockholder and that the
     stockholder intends thereby to demand the appraisal of such stockholder's
     shares. A proxy or vote against the merger or consolidation shall not
     constitute such a demand. A stockholder electing to take such action must
     do so by a separate written demand as herein provided. Within 10 days after
     the effective date of such merger or consolidation, the surviving or
     resulting corporation shall notify each stockholder of each constituent
     corporation who has complied with this subsection and has not voted in
     favor of or consented to the merger or consolidation of the date that the
     merger or consolidation has become effective; or

          (2) If the merger or consolidation was approved pursuant to sec. 228
     or sec. 253 of this title, then either a constituent corporation before the
     effective date of the merger or consolidation or the surviving or resulting
     corporation within 10 days thereafter shall notify each of the holders of
     any class or series of stock of such constituent corporation who are
     entitled to appraisal rights of the approval of the merger or consolidation
     and that appraisal rights are available for any or all shares of such class
     or series of stock of such constituent corporation, and shall include in
     such notice a copy of this section. Such notice may, and, if given on or
     after the effective date of the merger or consolidation, shall, also notify
     such stockholders of the effective date of the merger or consolidation. Any
     stockholder entitled to appraisal rights may, within 20 days after the date
     of mailing of such notice, demand in writing from the surviving or
     resulting corporation the appraisal of such holder's shares. Such demand
     will be sufficient if it reasonably informs the corporation of the identity
     of the stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the facts stated therein. For purposes of
     determining the stockholders entitled to receive either notice, each
     constituent corporation may fix, in advance, a record date that shall be
     not more than 10 days prior to the date the notice is given, provided, that
     if the notice is given on or after the effective date of the merger or
     consolidation, the record date shall

                                       A-2


     be such effective date. If no record date is fixed and the notice is given
     prior to the effective date, the record date shall be the close of business
     on the day next preceding the day on which the notice is given.

     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw such stockholder's demand for appraisal and to accept the terms offered
upon the merger or consolidation. Within 120 days after the effective date of
the merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof, upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting from
the consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10 days
after such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted
such stockholder's certificates of stock to the Register in Chancery, if such is
required, may participate fully in all proceedings until it is finally
determined that such stockholder is not entitled to appraisal rights under this
section.

     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or

                                       A-3


compound, as the Court may direct. Payment shall be so made to each such
stockholder, in the case of holders of uncertificated stock forthwith, and the
case of holders of shares represented by certificates upon the surrender to the
corporation of the certificates representing such stock. The Court's decree may
be enforced as other decrees in the Court of Chancery may be enforced, whether
such surviving or resulting corporation be a corporation of this State or of any
state.

     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.

     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

                                       A-4
