                               SUMMARY TERM SHEET

     Delaware Miller Acquisition Corporation, which is referred to in this offer
to purchase as "Purchaser," is offering to purchase all of the outstanding
shares of common stock of Miller Building Systems, Inc. for $8.40 per share,
plus a future right to receive up to $.30 per Share, net to the seller in cash,
less any required withholding of taxes and without payment of interest, subject
to certain terms and conditions. The following are some of the questions you may
have, as a stockholder of Miller Building Systems, followed by answers to those
questions. We urge you to read carefully the remainder of this offer to purchase
and the accompanying letter of transmittal because the information in this
Summary Term Sheet is not complete. Additional important information is
contained in the remainder of this offer to purchase and the letter of
transmittal.

- WHO IS OFFERING TO BUY MY SECURITIES?

     Our name is Delaware Miller Acquisition Corporation. We are a Delaware
corporation formed for the purpose of making a tender offer for all of the
outstanding common stock of Miller Building Systems. We are an indirect wholly
owned subsidiary of Coachmen Industries, Inc., an Indiana corporation
("Coachmen"). See Section 8 of this offer to purchase -- "Certain Information
Concerning Coachmen and Purchaser."

- WHAT SECURITIES ARE BEING SOUGHT IN THE OFFER?

     We are seeking to purchase all of the outstanding shares of common stock of
Miller Building Systems. See "Introduction" and Section 1 of this offer to
purchase -- "Terms of the Offer."

- HOW MUCH ARE YOU OFFERING TO PAY, WHAT IS THE FORM OF PAYMENT AND WILL I HAVE
  TO PAY ANY FEES OR COMMISSIONS?

     We are offering to pay $8.40 per share, net to you, in cash, less any
required withholding of taxes without the payment of interest. You will also
receive a future right to receive up to $.30 per Share, net to you, in cash,
less any required withholding of taxes without the payment of interest, in the
event Miller Building Systems obtains a release or settlement agreement from a
third party on any claim it might have against Miller Building Systems to a
payment resulting from Miller Building Systems' termination of its agreement
with that company, or a final judgment with respect to that claim, in accordance
with certain terms and conditions. If you are the record owner of your shares
and you tender your shares to us in the offer, you will not have to pay
brokerage fees or similar expenses. If you own your shares through a broker or
other nominee, and your broker or nominee tenders your shares on your behalf,
your broker or nominee may charge you a fee for doing so. You should consult
your broker or nominee to determine whether any charges will apply. We will not
be obligated to pay or reimburse you for such broker or nominee charges. See the
"Introduction" Section of this offer to purchase. In addition, if you do not
complete and sign the Substitute Form W-9 included in the letter of transmittal,
you may be subject to required backup federal income tax withholding. See
Instruction 9 to the letter of transmittal.

- DO YOU HAVE THE FINANCIAL RESOURCES TO MAKE PAYMENT?

     Delaware Miller Acquisition Corporation will be provided with approximately
$28 million by its parent company, Coachmen. Those sums will be used to purchase
all shares validly tendered and not withdrawn in the offer and to provide
funding for the merger which is expected to follow the successful completion to
the offer. See Section 9 of this offer to purchase -- "Source and Amount of
Funds." Coachmen is the nation's largest producer of modular housing and a
leading full-line producer of recreational vehicles. As of December 31, 1999,
its latest fiscal year-end, Coachmen had total assets of $285.8 million and a
net income of $29.5 million. See Section 8 of this offer to purchase -- "Certain
Information Concerning Coachmen and Purchaser."

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

     We do not think our financial condition is relevant to your decision
whether to tender shares in the offer because: the offer is being made for all
outstanding shares solely for cash, the offer is not subject to any financing
conditions; and if we complete the offer, we will acquire all remaining shares
for the same cash price
                                        1
<PAGE>   5

through the merger of Delaware Miller Acquisition Corporation with and into
Miller Building Systems. See Section 9 of this offer to purchase -- "Source and
Amount of Funds."

- HOW LONG DO I HAVE TO DECIDE WHETHER TO TENDER IN THE OFFER?

     The offer will expire at 12:00 midnight New York City time, on October 19,
2000, unless we extend the offer. If you cannot deliver everything that is
required in order to make a valid tender by that time, you may be able to use a
guaranteed delivery procedure, which is described later in this offer to
purchase. See Sections 1 and 3 of this offer to purchase -- "Terms of the Offer"
and "Procedures for Accepting the Offer and Tendering Shares."

- CAN THE OFFER BE EXTENDED AND UNDER WHAT CIRCUMSTANCES?

     Subject to the terms of the merger agreement, we can extend the offer.
Under the merger agreement, we may extend the offer without the consent of
Miller Building Systems in the following circumstances:

     - Any of the conditions to the offer are not satisfied or waived by us on
       the expiration of the Offer (other than the Minimum Condition), until the
       conditions are satisfied or waived;

     - We are required to extend the offer for any period required by any rule,
       regulation, interpretation, or position of the Securities and Exchange
       Commission; or

     - All conditions to the offer are satisfied or waived, but the number of
       shares tendered and not withdrawn is less than 90% of the number of
       shares outstanding on a fully diluted basis, we may extend the offer to
       provide for a subsequent offering period not to exceed 20 business days.

     A subsequent offering period, if one is included, will be an additional
opportunity for stockholders to tender their shares and receive the offer
consideration following the expiration of the offer. See Section 1 of this offer
to purchase, "Terms of the Offer," for more details on our ability to extend the
offer.

- HOW WILL I BE NOTIFIED IF THE OFFER IS EXTENDED?

     If we extend the offer, we will make a public announcement no later than
9:00 a.m., New York City time, on the next business day after the day on which
the offer was scheduled to expire. We also will inform First Chicago Trust
Company of New York, the depositary for the offer (the "Depositary") of the
extension. See Section 1 of this offer to purchase -- "Terms of the Offer."

- WHAT ARE THE MOST SIGNIFICANT CONDITIONS TO THE OFFER?

     We are not obligated to purchase any tendered shares unless at least 51% of
the outstanding shares of Miller Building Systems on a fully diluted basis,
including all shares issuable upon exercise of all vested and unvested stock
options, are validly tendered and not withdrawn. We call this condition the
"Minimum Condition." The offer is also subject to a number of other conditions
including the expiration or termination of any applicable waiting period under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. We can
waive any of the conditions to the offer without the consent of Miller Building
Systems, other than the Minimum Condition. See Sections 1, 9 and 15 of this
offer to purchase -- "Terms of the Offer," "Source and Amount of Funds" and
"Certain Conditions of the Offer." The offer is not conditioned on our receiving
financing.

- HOW DO I TENDER MY SHARES?

     If you are a record holder of shares of common stock of Miller Building
Systems and have your stock certificate(s), you must tender your shares by
delivering the certificates representing your shares, together with a completed
letter of transmittal and any other documents required by the letter of
transmittal, to the Depositary, not later than the time the tender offer expires
or follow the procedures described in this offer to purchase for book-entry
transfer. If your shares are held in street name, the shares can be tendered by
your nominee through the Depositary. If you are a record holder but your stock
certificate(s) is not available to you

                                        2
<PAGE>   6

or you cannot deliver your stock certificate(s) to the Depositary by the
expiration of the offer, you may be able to tender your shares using the
attached Notice of Guaranteed Delivery. See Section 3 of this offer to
purchase -- "Procedures for Accepting the Offer and Tendering Shares."

- WHEN WILL I GET PAID IF I TENDER MY SHARES?

     If all of the conditions of the offer are satisfied or waived and your
shares of Miller Building Systems common stock are accepted for payment, we will
pay you promptly after the expiration of the offer. See Section 2 of this offer
to purchase -- "Acceptance for Payment and Payment for Shares."

- UNTIL WHAT TIME CAN I WITHDRAW PREVIOUSLY TENDERED SHARES?

     You can withdraw previously tendered shares at any time until the offer has
expired and, in addition, if we have not agreed to accept your shares for
payment by October 19, 2000, you can withdraw them at any time after that date
until we accept the shares for payment. See Section 4 of this offer to
purchase -- "Withdrawal Rights."

- HOW DO I WITHDRAW PREVIOUSLY TENDERED SHARES?

     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. If you tendered by giving
instructions to a broker or bank, you must instruct the broker or bank to
arrange for the withdrawal of your shares. See Section 4 of this offer to
purchase -- "Withdrawal Rights."

- WILL I HAVE WITHDRAWAL RIGHTS DURING ANY SUBSEQUENT OFFERING PERIOD, IF ONE IS
  PROVIDED?

     No. If there is a subsequent offering period, we will already have accepted
shares purchased in the initial offering period, and we will accept and pay for
shares tendered during the subsequent offering period immediately, and thus you
will not be able to withdraw shares during any subsequent offering period.
However, if we extend the offer without accepting any shares you will have
withdrawal rights during this extension. See Section 4 of this offer to
purchase -- "Withdrawal Rights."

- WHAT DOES THE BOARD OF DIRECTORS OF MILLER BUILDING SYSTEMS THINK OF THE
  OFFER?

     We are making the offer pursuant to an Agreement and Plan of Merger, dated
as of August 22, 2000, among Miller Building Systems, Coachmen, COA Housing
Group, Inc., an Indiana corporation wholly owned by Coachmen, which is our
parent, and us. The Board of Directors of Miller Building Systems (i) has
determined that each of the offer and the merger is advisable, fair to and in
the best interests of the stockholders of Miller Building Systems, (ii) has
approved the merger agreement, the offer and the merger, and (iii) recommends
that stockholders accept the offer by tendering their shares. See the
"Introduction" Section to this offer to purchase.

- IF A MAJORITY OF THE SHARES ARE TENDERED AND ACCEPTED FOR PAYMENT, WILL MILLER
  BUILDING SYSTEMS CONTINUE AS A PUBLIC COMPANY?

     No. If we purchase all of the tendered shares and the merger takes place,
Miller Building Systems no longer will be publicly owned. Even if the merger
does not take place, if we purchase all the tendered shares:

     - there may be so few remaining stockholders and publicly held shares that
       the common stock of Miller Building Systems no longer will be eligible to
       be traded through the Nasdaq National Market,

     - there may not be a public trading market for Miller Building Systems
       common stock, and

     - Miller Building Systems may cease making filings with the Securities and
       Exchange Commission or otherwise cease being required to comply with the
       Securities and Exchange Commission's rules relating to publicly held
       companies.

     See Section 13 of this offer to purchase -- "Certain Effects of the Offer."

                                        3
<PAGE>   7

- WHAT WILL HAPPEN IF A MAJORITY OF THE SHARES OF MILLER BUILDING SYSTEMS ARE
  TENDERED AND ACCEPTED FOR PAYMENT IN THE OFFER?

     If we purchase in the offer at least 51% of the outstanding shares of
Miller Building Systems on a fully diluted basis and all other applicable
conditions are met, Delaware Miller Acquisition Corporation will be merged with
and into Miller Building Systems. If that merger takes place, COA Housing Group,
Inc. and its affiliates will own all of the shares of Miller Building Systems
and all remaining stockholders of Miller Building Systems will receive $8.40 per
share, plus a future right to receive up to $.30 per share, net to the seller in
cash, less any required withholding of taxes and without payment of interest,
subject to certain terms and conditions. See "Introduction" and Section 12 of
this offer to purchase -- "Purpose of the Offer; Plans for the Company; Other
Matters." There are no appraisal rights available in connection with the offer.
However, if the merger takes place, stockholders who have not sold their shares
in the offer will have appraisal rights under Delaware law. See the
"Introduction" and Section 17 of this offer to purchase -- "Appraisal Rights."

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

     If the merger described above takes place, stockholders not tendering in
the offer will receive the same amount of cash per share in the merger that they
would have received had they tendered their shares in the offer, subject to any
dissenters' rights properly exercised under Delaware law. Therefore, if the
merger takes place, the only difference to you between tendering your shares and
not tendering your shares is that if you tender your shares in the offer, you
will be paid earlier and not have dissenters' rights. If, however, for some
reason the merger does not take place, the number of stockholders and the number
of shares of Miller Building Systems that are still publicly held may be so
small that there no longer will be an active public trading market or, possibly,
there may not be any public trading market for the Miller Building Systems
common stock. Also, as described above, Miller Building Systems may cease making
filings with the Securities and Exchange Commission or otherwise may not be
required to comply with the Securities and Exchange Commission rules relating to
publicly held companies. See the "Introduction" and Section 13 of this offer to
purchase -- "Certain Effects of the Offer."

- WHAT HAPPENS IF I TENDER MY SHARES AND YOU DO NOT ACCEPT THE TENDERED SHARES?

     If any shares of common stock of Miller Building Systems that you tender
are not accepted for any reason, certificates representing those shares will be
returned to you or to the person you specify in your tendering documents.

- WHAT WAS THE MARKET VALUE OF MY SHARES OF MILLER BUILDINGS SYSTEMS COMMON
  STOCK AS OF A RECENT DATE?

     On August 22, 2000, the last full trading day before we announced our
proposal to acquire all of the outstanding shares of common stock of Miller
Building Systems, the closing price of Miller Building Systems common stock
reported on the Nasdaq National Market was $7.625 per share. Between June 30,
2000 and August 22, 2000, the closing price of a share of Miller Building
Systems common stock ranged between $7.25 and $8.438. On September 19, 2000, the
last trading day before we commenced the offer, the last sale price of the
common stock was $8.1875 per share. We advise you to obtain a recent quotation
for shares of Miller Building Systems common stock in deciding whether to tender
your shares in the offer. See Section 6 of this offer to purchase --"Price Range
of Shares."

- WHAT ARE THE MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF TENDERING SHARES?

     The receipt of cash for shares pursuant to the offer or the merger will be
a taxable transaction for United States federal income tax purposes and possibly
for state, local and foreign income tax purposes as well. In general, a
stockholder who sells shares pursuant to the tender offer or receives cash in
exchange for shares pursuant to the merger will recognize gain or loss for
United States federal income tax purposes equal to the difference, if any,
between the amount of cash received and the stockholder's adjusted tax basis in
the shares sold pursuant to the tender offer or exchanged for cash pursuant to
the merger. If the shares exchanged constitute capital assets in the hands of
the stockholder, such gain or loss will be capital gain or loss. In general,
capital gains recognized by an individual will be subject to a maximum United
States federal income

                                        4
<PAGE>   8

tax rate of 20% if the shares were held for more than one year, and if held for
one year or less they will be subject to tax at ordinary income tax rates. See
Section 5 of this offer to purchase -- "Material U.S. Federal Income Tax
Considerations."

- WHO CAN I TALK TO IF I HAVE QUESTIONS ABOUT THE TENDER OFFER?

     You can call Innisfree M&A Incorporated ("Innisfree") at (888) 750-5834
(toll free). Innisfree is acting as the information agent for our tender offer.

To the Holders of Shares of Common Stock
of Miller Building Systems, Inc.:

                                  INTRODUCTION

     Delaware Miller Acquisition Corporation, a Delaware corporation
("Purchaser") and a wholly owned subsidiary of the COA Housing Group, Inc., an
Indiana corporation ("Parent") which is a wholly owned subsidiary of Coachmen
Industries, Inc., an Indiana corporation ("Coachmen"), hereby offers to purchase
all of the outstanding shares of common stock (the "Shares") of Miller Building
Systems, Inc., a Delaware corporation (the "Company"), at a price of $8.40 per
Share, plus a future right to receive up to $.30 per Share, net to the seller in
cash, less any required withholding of taxes and without payment of interest
(the "Offer Price"), upon the terms and subject to the conditions set forth in
this offer to purchase (the "Offer to Purchase") and the related letter of
transmittal (the "Letter of Transmittal," which, together with the Offer to
Purchase, as each may be amended or supplemented from time to time, collectively
constitute the "Offer").

     Tendering stockholders who are record owners of their Shares and tender
directly to the Depositary (as defined below) will not be obligated to pay
brokerage fees or commissions or, except as otherwise provided in Instruction 6
of the Letter of Transmittal, stock transfer taxes with respect to the purchase
of Shares by Purchaser pursuant to the Offer. Stockholders who hold their Shares
through a broker or bank should consult that institution as to whether it
charges any service fees. However, any tendering stockholder or other payee who
fails to complete and sign the Substitute Form W-9 that is included in the
Letter of Transmittal may be subject to a required federal backup withholding
tax of 31% of the gross proceeds payable to the stockholder or other payee
pursuant to the Offer. See Sections 3 and 5 of this Offer to
Purchase -- "Procedures for Accepting the Offer and Tendering Shares" and
"Material U.S. Federal Income Tax Considerations." Parent or Purchaser will pay
all charges and expenses of First Chicago Trust Company of New York as
depositary (the "Depositary") and Innisfree M&A Incorporated as information
agent (the "Information Agent"), incurred in connection with the Offer. See
Section 18 of this Offer to Purchase -- "Fees and Expenses."

     THE BOARD OF DIRECTORS OF THE COMPANY (THE "COMPANY BOARD") (I) HAS
DETERMINED THAT EACH OF THE OFFER AND THE MERGER IS ADVISABLE, FAIR TO AND IN
THE BEST INTERESTS OF THE STOCKHOLDERS OF THE COMPANY, (II) HAS APPROVED THE
MERGER AGREEMENT, THE OFFER AND THE MERGER, AND (III) RECOMMENDS THAT
STOCKHOLDERS OF THE COMPANY ACCEPT THE OFFER AND TENDER THEIR SHARES PURSUANT TO
THE OFFER.

     Morgan Keegan & Company, Inc., financial advisor to the Company ("Morgan
Keegan"), has delivered to the Company Board a written opinion dated August 22,
2000, to the effect that, as of that date and based on and subject to the
matters described in the opinion, the $8.40 per Share, plus the future right to
receive up to $.30 per Share, cash consideration to be received by the holders
of Shares in the Offer and the Merger is fair to holders from a financial point
of view. Morgan Keegan was engaged by the Company pursuant to the terms of an
engagement letter to advise the Company with respect to a proposed acquisition
of the Company by Purchaser and to undertake an analysis to enable Morgan Keegan
to provide an opinion to the Company Board as to the fairness to the Company or
its stockholders. Pursuant to the terms of a letter agreement, dated July 29,
1998 and amended on March 1, 1999, June 14, 2000 and August 4, 2000, the Company
paid Morgan Keegan a non-refundable cash retainer fee of approximately $50,000
in two installments following execution of the first amendment to the engagement
letter, and agreed to pay Morgan Keegan a cash fee of $250,000, with $100,000
due upon delivery of a fairness opinion (whether oral or written, as requested
by the Company) and the remaining $150,000 due upon the closing of a transfer of
control of, or a material interest in, the Company or any of its businesses or
all or a material amount of any of their respective assets, which would include
the transactions contemplated by the Merger Agreement. The Company has also
agreed to reimburse Morgan Keegan for all reasonable out-of-pocket expenses
(including reasonable fees and disbursements of counsel), and to indemnify
Morgan Keegan and certain related parties, and hold each of them harmless
against any and all losses, claims, damages or liabilities to which such parties
may become subject related to or arising out of Morgan Keegan's engagement. A
copy of Morgan Keegan's written opinion, which describes the assumptions

                                        1

made, procedures followed, matters considered and limitations on the review
undertaken, is contained in the Company's Solicitation/Recommendation Statement
on Schedule 14D-9 (the "Schedule 14D-9") filed with the Securities and Exchange
Commission (the "SEC") on September 20, 2000 in connection with the Offer.
Stockholders are urged to read the full text of Morgan Keegan's opinion
carefully in its entirety.

     THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, (I) THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER AT LEAST 51% OF
THE OUTSTANDING SHARES ON A FULLY DILUTED BASIS (INCLUDING ALL SHARES ISSUABLE
UPON EXERCISE OF ALL VESTED AND UNVESTED STOCK OPTIONS) (THE "MINIMUM
CONDITION") AND (II) ANY APPLICABLE WAITING PERIOD UNDER THE HART-SCOTT-RODINO
ANTITRUST IMPROVEMENTS ACT OF 1976, AS AMENDED (THE "HSR ACT"), APPLICABLE TO
THE PURCHASE OF SHARES PURSUANT TO THE OFFER OR THE MERGER HAVING BEEN
TERMINATED OR HAVING EXPIRED (THE "HSR CONDITION"). THE OFFER ALSO IS SUBJECT TO
CERTAIN OTHER CONDITIONS DESCRIBED IN SECTION 15 OF THE OFFER TO
PURCHASE -- "CERTAIN CONDITIONS OF THE OFFER." As used in this Offer to
Purchase, "on a fully diluted basis" means, as of any time, on a basis that
includes the number of Shares that are actually issued and outstanding plus the
maximum number of Shares that the Company may be required to issue pursuant to
obligations under stock options or other rights and securities exercisable or
exchangeable for, or convertible into, Shares, whether or not currently
exercisable. The Company has represented and warranted to Purchaser that, as of
August 23, 2000, 3,074,092 Shares were issued and outstanding and 1,050,000
Shares were reserved for issuance pursuant to Company stock options, of which
578,009 Shares were subject to outstanding stock options. As of the date of this
Offer to Purchase, neither Coachmen or Parent beneficially own any Shares or
rights to acquire Shares. See Section 12 of this Offer to Purchase -- "Purpose
of the Offer and the Merger; Plans for the Company; Other Matters." Based on the
foregoing, the Minimum Condition would be satisfied if at least 1,863,000 Shares
are validly tendered and not withdrawn prior to the Expiration Date (as defined
below in Section 1 of this Offer to Purchase). The number of Shares required to
be validly tendered and not withdrawn in order to satisfy the Minimum Condition
will increase to the extent additional Shares are deemed to be outstanding on a
fully diluted basis under the terms and conditions of the Merger Agreement (as
defined below).

     The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of August 22, 2000, among the Company, Coachmen, Parent and Purchaser (the
"Merger Agreement"). The Merger Agreement provides that Purchaser will be merged
with and into the Company (the "Merger"). Following the Merger, the Company will
continue as the surviving corporation (the "Surviving Corporation") and a wholly
owned subsidiary of Parent and an indirect wholly owned subsidiary of Coachmen,
and the separate corporate existence of Purchaser shall cease. Pursuant to the
Merger Agreement, each Share issued and outstanding immediately prior to the
effective time of the Merger (the "Effective Time") shall be converted into and
shall become the right to receive an amount in cash equal to the Offer Price,
without interest (the "Merger Consideration"). The Merger Agreement is more
fully described in Section 11 of this Offer to Purchase -- "The Merger
Agreement; Other Arrangements," which also contains a discussion of the
treatment of stock options.

     The Merger is subject to the satisfaction or waiver of certain conditions,
including, if required, the approval and adoption of the Merger Agreement by a
majority of the stockholders of the Company. If the Minimum Condition and the
other conditions to the Offer are satisfied and the Offer is completed,
Purchaser will own a sufficient number of Shares to ensure that the Merger will
be approved without the affirmative vote of any other stockholder. Under Section
253 of the Delaware General Corporation Law ("DGCL") if, after completion of the
Offer, Purchaser owns at least 90% of the Shares then outstanding, Purchaser
will be able to cause the Merger to occur without a vote of the Company's
stockholders (a "short-form merger"). If, however, after completion of the Offer
Purchaser owns less than 90% of the then-outstanding Shares, a vote of the
Company's stockholders will be required under the DGCL to approve the Merger.
See Section 11 of this Offer to Purchase -- "The Merger Agreement; Other
Arrangements." The Company has agreed, if required, to duly call, give notice
of, convene and hold a meeting of its stockholders, to be held as soon as
promptly as reasonably practicable after the Tender Offer Purchase Time (as
defined below) for the purpose of obtaining

                                        2
<PAGE>   11

stockholder approval of the Merger Agreement and the transactions contemplated
thereby. See Section 11 of this Offer to Purchase -- "The Merger Agreement;
Other Arrangements."

     No appraisal rights are available in connection with the Offer; however,
stockholders may have appraisal rights in connection with the Merger. See
Section 17 of this Offer to Purchase -- "Appraisal Rights."

     THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION THAT SHOULD BE READ CAREFULLY AND IN THEIR ENTIRETY BEFORE
ANY DECISION IS MADE WITH RESPECT TO THE OFFER.

                                THE TENDER OFFER

1. TERMS OF THE OFFER

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of the extension or
amendment), Purchaser will accept for payment and pay the Offer Price for all
Shares validly tendered and not properly withdrawn prior to 12:00 midnight, New
York City time, on October 19, 2000 (the "Expiration Date") as permitted under
Section 4 of this Offer to Purchase -- "Withdrawal Rights." The term "Initial
Expiration Date" means the foregoing Expiration Date without extension. If
Purchaser, in accordance with the terms of the Merger Agreement, extends the
deadline for tendering Shares, the term "Expiration Date" means the latest time
and date on which the Offer, as so extended, expires.

     The Offer is subject to the Minimum Condition, that is there having been
validly tendered at least 51% of the outstanding Shares on a fully diluted
basis. The Offer also is conditioned upon the expiration or termination of any
applicable waiting period under the HSR Act. The Offer also is subject to the
other conditions described in Section 15 of this Offer to Purchase -- "Certain
Conditions of the Offer."

     Extension of the Offer. Parent expressly reserves the right, in its sole
discretion (but subject to the terms and conditions of the Merger Agreement and
the applicable rules and regulations of the SEC), at any time and from time to
time, to cause Purchaser to extend the period of time during which the Offer is
open by giving oral or written notice of such extension to the Depositary.
During any extension, all Shares previously tendered and not withdrawn will
remain subject to the Offer, subject to the right of a tendering stockholder to
withdraw such stockholder's Shares. See Section 4 of this Offer to
Purchase -- "Withdrawal Rights."

     Purchaser also expressly reserves the right, in its sole discretion, at any
time and from time to time, to waive, in whole or in part, any conditions of the
Offer. However, pursuant to the Merger Agreement, Purchaser has agreed that it
will not, unless previously approved by the Company in writing, make any change
that (i) decreases the Offer Price, (ii) changes the form of consideration to be
paid in the Offer, (iii) reduces the maximum number of Shares to be purchased in
the Offer, (iv) imposes additional conditions on the Offer other than those
conditions set forth in the Merger Agreement, (v) amends the conditions in the
Offer to broaden the conditions, (vi) extends the Offer except as provided in
the Merger Agreement, or (vii) amends the Minimum Condition.

     Pursuant to the Merger Agreement, Parent may, without the consent of the
Company Board, cause Purchaser to extend the Offer (i) if at the Initial
Expiration Date any of the conditions to the Offer have not been satisfied or
waived (other than the Minimum Condition), until such time as the conditions are
satisfied or waived, (ii) for any period required by any rule, regulation,
interpretation or position of the SEC applicable to the Offer, or (iii) by
including a Subsequent Offering Period (as defined below) that would extend the
Offer for an aggregate period not to exceed 20 business days if all of the
conditions to the Offer are satisfied or waived but the number of Shares validly
tendered and not withdrawn is less than 90% of the then-outstanding number of
Shares on a fully diluted basis. In the event that Purchaser includes a
Subsequent Offering Period, Purchaser must accept and promptly pay for all
Shares tendered prior to the date of extension and must otherwise meet the
requirements of Rule 14d-11 under the Securities Exchange Act of 1934 (the
"Exchange Act") in connection with each extension.

     The rights reserved in the foregoing paragraphs are in addition to the
rights set forth in Section 15 of this Offer to Purchase -- "Certain Conditions
of the Offer."

     Any extension, delay, termination, waiver or amendment will be followed as
promptly as practicable by public announcement. An announcement, in the case of
an extension, will be made no later than 9:00 a.m., New York City time, on the
next business day after the previously scheduled expiration of the Offer, in
accordance with the public announcement requirements of Rule 14e-1(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 material changes be promptly
disseminated to stockholders in a manner reasonably designed to inform them of
the changes) and without limiting the manner in which Purchaser may choose to
make any public

                                        4
<PAGE>   13

announcement, Purchaser shall have no obligation to publish, advertise or
otherwise communicate any public announcement other than by issuing a press
release to the Dow Jones News Service.

     If, subject to the Merger Agreement, Purchaser makes a material change in
the terms of the Offer or the information concerning the Offer or waives a
material condition of the Offer, Purchaser will disseminate additional tender
offer materials (including by public announcement as set forth above) and extend
the Offer to the extent required by Rules 14d-4(d), 14d-6(c) and 14e-1 under the
Exchange Act. These rules generally provide that the minimum period during which
a tender 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. In the SEC's view, an offer should remain open for a
minimum of five business days from the date the material change is first
published, sent or given to stockholders, and, if material changes are made with
respect to information that approaches the significance of price and the number
of securities sought, a minimum of ten business days may be required to allow
for adequate dissemination and investor response. With respect to a change in
price, a minimum ten business day period from the date of the change is
generally required to allow for adequate dissemination to stockholders.
Accordingly, if, prior to the Expiration Date, Purchaser increases or decreases
the consideration offered pursuant to the Offer, and if the Offer is scheduled
to expire at any time earlier than the tenth business day from the date that
notice of the increase or decrease is first published, sent or given to holders
of Shares, Purchaser will extend the Offer at least until the expiration of such
tenth business day. For purposes of the Offer, a "business day" means any day
other than a Saturday, Sunday or a federal holiday and consists of the time
period from 12:01 a.m. through 12:00 midnight, New York City time.

     Pursuant to the Merger Agreement, Purchaser has agreed that, upon the terms
and subject to the conditions to the Offer, Purchaser shall accept for payment,
purchase and pay for all Shares that have been validly tendered and not
withdrawn pursuant to the Offer as soon as practicable after the Initial
Expiration Date and promptly upon tender in any Subsequent Offering Period.

     The Company has provided Parent and Purchaser with the Company's
stockholder list and security position listings for the purpose of disseminating
the Offer to holders of Shares. This Offer to Purchase and the related Letter of
Transmittal will be mailed to record holders of Shares whose names appear on the
Company's stockholder list and will be furnished, for subsequent transmittal to
beneficial owners of Shares, to brokers, dealers, commercial banks, trust
companies and similar persons whose names, or the names of whose nominees,
appear on the stockholder list or, if applicable, who are listed as participants
in a clearing agency's security position listing.

     Subsequent Offering Period. Pursuant to Rule 14d-11 under the Exchange Act,
Purchaser may, subject to certain conditions, include a subsequent offering
period following the expiration of the Offer on the Expiration Date (the
"Subsequent Offering Period"). Rule 14d-11 provides that Purchaser may include a
Subsequent Offering Period so long as, among other things, (i) the Offer remains
open for a minimum of 20 business days and has expired, (ii) the Offer is for
all outstanding Shares, (iii) Purchaser accepts and promptly pays for all Shares
tendered during the Offer, (iv) Purchaser announces the results of the Offer,
including the approximate number and percentage of Shares deposited, no later
than 9:00 a.m. New York City time on the next business day after the Expiration
Date and immediately begins the Subsequent Offering Period, (v) Purchaser
immediately accepts and promptly pays for Shares as they are tendered during the
Subsequent Offering Period, and (vi) Purchaser pays the Offer Price for all
Shares tendered in the Subsequent Offering Period. Purchaser will be able to
include a Subsequent Offering Period if it satisfies the conditions above. In
the event Purchaser elects to include a Subsequent Offering Period, it will
notify stockholders of the Company consistent with the requirements of the SEC.

     A Subsequent Offering Period, if one is included, is not an extension of
the Offer. Instead, a Subsequent Offering Period would be an additional period
of time, following the expiration of the Offer, in which stockholders may tender
Shares not tendered into the Offer. The Merger Agreement provides that, if all
of the conditions to the Offer are satisfied or waived but the number of Shares
validly tendered and not withdrawn is less than 90% of the then-outstanding
number of Shares on a fully diluted basis, Purchaser may include a

                                        5
<PAGE>   14

]Subsequent Offering Period that would extend the Offer for an aggregate period
of time from 3 business days to 20 business days in length. In the event that
Purchaser includes a Subsequent Offering Period, Purchaser must accept and
promptly pay for all securities tendered on or before the Expiration Date and
must otherwise meet the requirements of Rule 14d-11 under the Exchange Act in
connection with the Subsequent Offering Period.

     Purchaser may include a Subsequent Offering Period in the event that all of
the conditions to the Offer have been satisfied or waived but less than 90% of
the outstanding Shares on a fully diluted basis have been validly tendered and
not properly withdrawn as of the Expiration Date. If a Subsequent Offering
Period is included, pursuant to Rule 14d-7 under the Exchange Act, no withdrawal
rights would apply to Shares tendered during the Subsequent Offering Period and
no withdrawal rights would apply during the Subsequent Offering Period with
respect to Shares tendered in the Offer and accepted for payment. The same
consideration, the Offer Price, would be paid to stockholders tendering Shares
in the Offer or in any Subsequent Offering Period, if one is included.

2. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES

     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), Purchaser will accept for payment and will pay for, as soon as
practicable after the Expiration Date, all Shares validly tendered prior to the
Expiration Date and not properly withdrawn in accordance with Section 4 of this
Offer to Purchase -- "Withdrawal Rights."

     In all cases, Purchaser will pay for Shares purchased in the Offer only
after timely receipt by the Depositary of (i) the certificates representing the
Shares (the "Share Certificates") or confirmation (a "Book-Entry Confirmation")
of a book-entry transfer of the Shares into the Depositary's account at The
Depositary Trust Company (the "Book-Entry Transfer Facility") pursuant to the
procedures set forth in Section 3 of this Offer to Purchase -- "Procedures for
Accepting the Offer and Tendering Shares," (ii) the Letter of Transmittal,
properly completed and duly executed, with any required signature guarantees or,
in the case of a book-entry transfer, an Agent's Message (as defined below) in
lieu of the Letter of Transmittal, and (iii) any other documents required under
the Letter of Transmittal. The procedures for tendering Shares and guaranteed
delivery set forth in Section 3 of this Offer to Purchase will apply during any
Subsequent Offering Period.

     "Agent's Message" means a message transmitted by a Book-Entry Transfer
Facility to, and received by, the Depositary and forming a part of a Book-Entry
Confirmation, which message states that the Book-Entry Transfer Facility has
received an express acknowledgment from the participant in the Book-Entry
Transfer Facility tendering the Shares which are the subject of the Book-Entry
Confirmation that the participant has received and agrees to be bound by the
terms of the Letter of Transmittal and that Purchaser may enforce that agreement
against the participant.

     For purposes of the Offer, Purchaser will be deemed to have accepted for
payment (and thereby purchased) Shares validly tendered and not properly
withdrawn as, if and when Purchaser gives oral or written notice to the
Depositary of Purchaser's acceptance for payment of the Shares pursuant to the
Offer. Upon the terms and subject to the conditions of the Offer, payment for
Shares accepted for payment pursuant to the Offer will be made by deposit of the
purchase price for the Shares with the Depositary, which will act as agent for
tendering stockholders for the purpose of receiving payments from Purchaser and
transmitting payments to tendering stockholders whose Shares have been accepted
for payment.

     UNDER NO CIRCUMSTANCES WILL PURCHASER PAY INTEREST ON THE OFFER PRICE TO BE
PAID FOR THE SHARES, REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY DELAY IN
MAKING PAYMENT.

     Purchaser reserves the right, in its sole discretion, to delay the
acceptance for payment of, or the payment for, any tendered Shares in order to
comply in whole or in part with any applicable law. If Purchaser is delayed in
its acceptance for payment of, or payment for, Shares or is unable to accept for
payment, or pay for, Shares pursuant to the Offer for any reason, then, without
prejudice to Purchaser's rights under the Offer (including

                                        6
<PAGE>   15

the rights set forth in Sections 1 and 15 of this Offer to Purchase -- "Terms of
the Offer" and "Certain Conditions of the Offer"), the Depositary may,
nevertheless, on behalf of Purchaser, 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 Section 4 of this
Offer to Purchase -- "Withdrawal Rights." The reservation by Purchaser of the
right to delay the acceptance of or payment for Shares is subject to the
provisions of Rule 14e-1(c) under the Exchange Act, which requires Purchaser to
pay the consideration offered or return the Shares deposited by or on behalf of
tendering stockholders promptly after the termination or withdrawal of the
Offer.

     If any tendered Shares are not purchased pursuant to the Offer for any
reason, or if Share Certificates are submitted representing more Shares than are
tendered, any Share Certificates not tendered or not accepted for purchase will
be returned to the tendering stockholder, or such other person as the tendering
stockholder shall specify in the Letter of Transmittal, as promptly as
practicable following the expiration, termination or withdrawal of the Offer. In
the case of Shares delivered by book-entry transfer into the Depositary's
account at the Book-Entry Transfer Facility pursuant to the procedures set forth
in Section 3 of this Offer to Purchase -- "Procedures for Accepting the Offer
and Tendering Shares," the Shares will be credited to the account maintained at
the Book-Entry Transfer Facility that the tendering stockholder specifies in the
Letter of Transmittal, as promptly as practicable following the expiration,
termination or withdrawal of the Offer. If no instructions are given with
respect to Shares delivered by book-entry transfer, any Shares not tendered or
not purchased will be returned by crediting the account at the Book-Entry
Transfer Facility designated in the Letter of Transmittal as the account from
which the Shares were delivered.

     If, prior to the Expiration Date, Purchaser increases the Offer Price,
Purchaser will pay the Offer Price, as increased, to all holders of Shares that
are purchased in the Offer, whether or not the Shares were tendered before the
increase in the Offer Price.

     Purchaser reserves the right to transfer or assign, in whole or in part,
from time to time, to one or more direct or indirect subsidiaries of Parent, the
right to purchase all or any portion of the Shares tendered pursuant to the
Offer, but any transfer or assignment will not relieve Purchaser of its
obligations under the Offer and will in no way prejudice the rights of tendering
stockholders to receive payment for Shares validly tendered and accepted for
payment pursuant to the Offer.

3. PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING SHARES

     Valid Tenders. To tender Shares pursuant to the Offer, a stockholder must
comply with one of the following (i) a properly completed and duly executed
Letter of Transmittal in accordance with the instructions of the Letter of
Transmittal, with any required signature guarantees, certificates for the Shares
to be tendered and any other documents required by the Letter of Transmittal
must be received by the Depositary at one of its addresses set forth on the back
cover of this Offer to Purchase prior to the Expiration Date, (ii) Shares must
be properly delivered pursuant to the procedures for book-entry transfer
described below and a confirmation of such delivery received by the Depositary
which confirmation must include an Agent's Message if the tendering stockholder
has not delivered a Letter of Transmittal prior to the Expiration Date, or (iii)
the tendering stockholder must comply with the guaranteed delivery procedures
set forth below.

     Book-Entry Transfer. The Depositary will establish accounts with respect to
the Shares at The Depositary Trust Company (the "Book-Entry Transfer Facility")
for purposes of the Offer within two (2) business days after the date of this
Offer to Purchase. Any financial institution that is a participant in the system
of the Book-Entry Transfer Facility may make book-entry delivery of Shares by
causing the Book-Entry Transfer Facility to transfer such Shares into the
Depositary's account at the Book-Entry Transfer Facility in accordance with the
Book-Entry Transfer Facility's procedures for such transfer. However, although
delivery of Shares may be effected through book-entry transfer into the
Depositary's account at the Book-Entry Transfer Facility, either the Letter of
Transmittal, properly completed and duly executed, together with any required
signature guarantees, or an Agent's Message in lieu of the Letter of
Transmittal, and any other required documents, must, in any case, be received by
the Depositary at one of its addresses set forth on

                                        7
<PAGE>   16

the back cover of this Offer to Purchase prior to the Expiration Date, or the
tendering stockholder must comply with the guaranteed delivery procedure
described below.

     DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE
WITH THE BOOK-ENTRY TRANSFER FACILITY'S PROCEDURES DOES NOT CONSTITUTE DELIVERY
TO THE DEPOSITARY. THE METHOD OF DELIVERY OF SHARES, THE LETTER OF TRANSMITTAL
AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY
TRANSFER FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING STOCKHOLDER.
SHARES WILL BE DEEMED DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY
(INCLUDING, IN THE CASE OF A BOOK-ENTRY TRANSFER A BOOK-ENTRY CONFIRMATION). IF
DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY
INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO
ENSURE TIMELY DELIVERY.

     Signature Guarantees. No signature guarantee is required on the Letter of
Transmittal where Shares are tendered (i) by a registered holder of Shares who
has not completed either the box labeled "Special Delivery Instructions" or the
box labeled "Special Payment Instructions" on the Letter of Transmittal or (ii)
for the account of a bank, broker, dealer, credit union, savings association or
other entity which is a member in good standing of a recognized Medallion
Program approved by the Securities Transfer Association Inc., including the
Securities Transfer Agents Medallion Program (STAMP), the Stock Exchange
Medallion Program (SEMP) and the New York Stock Exchange Medallion Signature
Guarantee Program (MSP) or any other "eligible guarantor institution" as defined
in Rule 17Ad-15 under the Exchange Act (each of the foregoing, an "Eligible
Institution"). In all other cases, all signatures on a Letter of Transmittal
must be guaranteed by an Eligible Institution. See Instruction 1 of the Letter
of Transmittal.

     If Share Certificates are registered in the name of a person or persons
other than the signer of the Letter of Transmittal, or if payment is to be made
or delivered, or Share Certificates not tendered or not accepted for payment are
to be returned, to a person other than the registered holder of the certificates
surrendered, then the Share Certificates must be endorsed or accompanied by an
appropriate duly executed stock powers, signed exactly as the name or names of
the registered holders or owners appear on the Share Certificates, with the
signatures on the certificates or stock powers guaranteed by an Eligible
Institution as provided in the Letter of Transmittal. See Instructions 1 and 5
of the Letter of Transmittal.

     Guaranteed Delivery. If a stockholder desires to tender Shares pursuant to
the Offer and such stockholder's Share Certificates are not immediately
available or the procedures for delivery by book-entry transfer cannot be
completed on a timely basis or time will not permit all required documents to
reach the Depositary prior to the Expiration Date, such stockholder's Shares may
be tendered; provided that all of the following conditions are satisfied:

     (i)  the tender is made by or through an Eligible Institution;

     (ii)  a properly completed and duly executed Notice of Guaranteed Delivery,
           substantially in the form provided by Purchaser, is received by the
           Depositary, as provided below, prior to the Expiration Date; and

     (iii) the Share Certificates for (or a Book-Entry Confirmation with respect
           to) such Shares, together with a properly completed and duly executed
           Letter of Transmittal, with any required signature guarantees, or, in
           the case of a book-entry transfer, an Agent's Message, and any other
           documents required by the Letter of Transmittal, are received by the
           Depositary within three trading days after the date of execution of
           such Notice of Guaranteed Delivery. A "trading day" is any day on
           which the Nasdaq National Market is open for business.

     The Notice of Guaranteed Delivery may be delivered by hand or mail or
transmitted by facsimile to the Depositary and must include a guarantee by an
Eligible Institution in the form set forth in the form of Notice of Guaranteed
Delivery made available by Purchaser.

                                        8
<PAGE>   17

     Notwithstanding any other provision of the Offer, Purchaser will pay for
Shares only after timely receipt by the Depositary of (i) the Share Certificates
representing such Shares, or Book-Entry Confirmation with respect to the Shares,
(ii) a properly completed and duly executed Letter of Transmittal, together with
any required signature guarantees (or, in the case of a book-entry transfer, an
Agent's Message), and (iii) any other documents required by the Letter of
Transmittal.

     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 Purchaser in its sole discretion, which
determination will be final and binding on all parties. Purchaser reserves the
absolute right to reject any and all tenders determined by it not to be in
proper form or the acceptance for payment of which may, in the opinion of its
counsel, be unlawful. Subject to the terms of the Merger Agreement, Purchaser
also reserves the absolute right to waive any defect or irregularity in the
tender of any Shares of any particular stockholder of the Company, whether or
not similar defects or irregularities are waived in the case of other
stockholders of the Company.

     Purchaser's interpretation of the terms and conditions of the Offer in this
regard (including the Letter of Transmittal and the instructions thereto) will
be final and binding. No tender of Shares will be deemed to have been validly
made until all defects and irregularities have been cured or waived. None of
Parent, Purchaser, Coachmen or any of their respective affiliates or assigns,
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.

     Appointment as Proxy. By executing the Letter of Transmittal (including
delivery through an Agent's Message), a tendering stockholder irrevocably
appoints designees of Purchaser as the stockholder's agents, attorneys-in-fact
and proxies, with full power of substitution, in the manner set forth in the
Letter of Transmittal, to the full extent of the stockholder's rights with
respect to the Shares tendered by the stockholder and accepted for payment by
Purchaser and with respect to any and all other Shares or other non-cash
dividends, distributions, securities or rights issued or issuable in respect of
those Shares on or after the date of this Offer to Purchase (collectively,
"Distributions"). All powers of attorney and proxies will be considered
irrevocable and coupled with an interest in the tendered Shares. This
appointment will be effective when, and only to the extent that, Purchaser
accepts the Shares for payment. Upon acceptance for payment, all other powers of
attorney and proxies given by the stockholder with respect to the Shares (and
any Distribution) and all other securities or rights prior to payment will be
revoked without further action, and no subsequent powers of attorney or proxies
may be given, nor may any subsequent written consent be executed by the
stockholder (and, if given or executed, will not be deemed to be effective),
with respect thereto. The designees of Purchaser will, with respect to the
Shares (and any Distribution) for which the appointment is effective, be
empowered to exercise all voting and other rights of the stockholder as they, in
their sole discretion, may deem proper at any annual or special meeting of the
Company's stockholders, or by written consent in lieu of any meeting or
otherwise. Purchaser reserves the right to require that, in order for Shares to

the procedures described in this Section 3 of this Offer to
Purchase -- "Procedures for Accepting the Offer and Tendering Shares."

     All questions as to the form, validity and eligibility (including time of
receipt) of any notice of withdrawal will be determined by Purchaser or its
designee, in its sole discretion, which determination will be final and binding.
No 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 notification.

5. MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

     The following is a summary of the material United States federal income tax
consequences to the Company's stockholders with respect to 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 the Company's stockholders, and assumes an
understanding of tax rules of general application. This summary is limited to
holders of Shares who hold the Shares as "capital assets" within the meaning of
Section 1221 of the Internal Revenue Code of 1986, as amended (the "Code"),
which generally includes property held for investment. It does not address
special rules which may apply to the Company's stockholders based on their tax
status, individual circumstances or other factors unrelated to the Offer or the
Merger. This summary is based upon laws, regulations, rulings and
interpretations currently in effect, all of which are subject to change,
retroactively or prospectively.

     The receipt of cash pursuant to the Offer or the Merger will constitute a
taxable transaction for U.S. federal income tax purposes under the Code, and may
also constitute a taxable transaction under applicable state, local, foreign
income and other tax laws. For U.S. federal income tax purposes, a stockholder
who sells Shares pursuant to the Offer or receives cash in exchange for Shares
pursuant to the Merger would generally recognize gain or loss in an amount equal
to the difference between the amount of cash received by the stockholder
pursuant to the Offer or the Merger and the stockholder's adjusted tax basis for
the Shares tendered and purchased pursuant to the Offer or exchanged for cash
pursuant to the Merger. If Shares sold or exchanged are held by a stockholder as
capital assets, that gain or loss will be capital gain or loss. Any such capital
gain or loss will be long term if, as of the date of the disposition of its
Shares, the stockholder held such Shares for more than one year or will be short
term if, as of such date, the stockholder held such Shares for one year or less.
Gain or loss will be determined separately for each block of Shares (i.e.,
Shares acquired at
                                       10
<PAGE>   19

the same cost in a single transaction) tendered pursuant to the Offer or
exchanged for cash pursuant to the Merger. In general, capital gains recognized
upon a disposition of a Share that has been held for more than one year will be
subject to a maximum United States federal income tax rate of 20% or, in the
case of a Share that has been held for one year or less, will be subject to tax
at ordinary income rates. Certain limitations apply to the tax treatment of a
stockholder's capital losses.

     Under U.S. federal income tax law, the amount of any payments made by the
Depositary to stockholders of the Company (other than certain exempt
stockholders, including, among others, all corporations and certain foreign
individuals and entities), pursuant to the Offer or the Merger may be subject to
backup withholding tax at a rate of 31%. To avoid backup withholding tax with
respect to payments made pursuant to the Offer or the Merger, each stockholder
must, unless an exemption applies and is proven in a manner satisfactory to the
Depositary, provide the Depositary with such stockholder's correct taxpayer
identifying number and certify under penalties of perjury that such stockholder
is not subject to backup federal income tax withholding by completing the
Substitute Form W-9 in the Letter of Transmittal. If backup withholding applies
with respect to a stockholder or if a stockholder fails to deliver a completed
Substitute Form W-9 to the Depositary or otherwise establish an exemption, the
Depositary is required to withhold 31% of any payments made to such stockholder.
See Instruction 9 of the Letter of Transmittal.

     The foregoing discussion may not be applicable to certain types of
stockholders of the Company, including stockholders who acquired Shares through
the exercise of employee stock options or otherwise as compensation, individuals
who are not citizens or residents of the United States, foreign corporations, or
entities that are otherwise subject to special tax treatment under the Code
(such as insurance companies, tax-exempt entities and regulated investment
companies).

     BECAUSE INDIVIDUAL CIRCUMSTANCES MAY DIFFER, ALL STOCKHOLDERS ARE
ENCOURAGED TO CONSULT THEIR OWN TAX ADVISORS TO DETERMINE THE PARTICULAR TAX
CONSEQUENCES TO THEM (INCLUDING THE APPLICATION AND EFFECT OF ANY STATE, LOCAL
OR FOREIGN INCOME AND OTHER TAX LAWS, INCLUDING ANY TAX RETURN FILING OR OTHER
TAX REPORTING REQUIREMENTS) OF THE OFFER AND THE MERGER.

10. BACKGROUND OF THE OFFER; PAST CONTACTS OR NEGOTIATIONS WITH THE COMPANY

     In July 1998, the Company engaged Morgan Keegan & Company, Inc. ("Morgan
Keegan") to explore its strategic alternatives, including the possibility of a
sale of the Company. On September 22, 1998, Morgan Keegan presented a report to
the Company Board on its evaluation of the strategic alternatives available and,
as directed by the Company Board, between September 1998 and January 1999,
Morgan Keegan identified and contacted several candidates, including Coachmen
and Modtech Holdings, Inc. ("Modtech"), for

                                       13
<PAGE>   22

potential merger with or acquisition of, the Company. On January 15, 1999, the
Company Board heard a full report on the results of Morgan Keegan's contacts,
including the values of and interests in the Company expressed by various
companies. Based on such report, the Company Board determined that the Company
should proceed further with negotiations with Modtech.

     Between January and September 1999, various representatives of the Company
met with Evan Gruber, the Chief Executive Officer of Modtech, to discuss
possible merger opportunities. On September 13, 1999, Modtech and the Company
entered into an agreement in principle to merge the Company with Modtech. Under
the terms of the agreement, the Company's stockholders were to receive common
stock and cash in exchange for their shares of the Company's common stock.
However, in November 1999, the parties mutually agreed to discontinue pursuit of
a merger based on market and other conditions.

     On April 6, 2000, Mr. Gruber met with Edward Craig, the Chief Executive
Officer of the Company, and inquired as to whether the Company had any continued
interest in a possible merger with Modtech. As a result of these discussions, on
or about June 6, 2000, Mr. Gruber submitted a proposal to acquire all of the
outstanding Shares of the Company at $8.05 per Share in an all-cash transaction.
The Company Board voted to accept this proposal and, on June 9, 2000, after
further negotiations, Modtech and the Company signed and accepted a letter
agreement. The original termination date of this letter agreement, July 10,
2000, was later extended to July 17, 2000.

     Between July 6, 2000 and July 10, 2000, the Company was approached by
representatives of Acquisitor PLC ("Acquisitor") to discuss the possibility of
Acquisitor submitting an alternative offer to purchase the Company.

     On July 11, 2000, Thomas Martini, the Vice President of Finance, Treasurer
and Secretary of the Company received a telephone call from Gene Stout, the
Executive Vice President of Coachmen, to discuss the possibility of Coachmen
submitting an alternative offer to purchase the Company.

     On July 13, 2000, the Company entered into a Standard Mutual Nondisclosure
Agreement with Coachmen.

     On July 13, 2000, during a meeting of the Company Board the Company
received a written proposal from Acquisitor (the "Acquisitor Proposal"). The
Company also received a letter from Coachmen during the meeting, indicating its
interest in purchasing all of the Company's Shares. The letter stated that
Coachmen would furnish a per share price range subject to approval of the Board
of Directors of Coachmen by July 17, 2000.

     At the July 13, 2000 meeting, the Company Board heard Morgan Keegan's
report on the various discussions and negotiations with Modtech, Acquisitor and
Coachmen, and approved and adopted the Third Amendment to the Employment
Agreement between the Company and Mr. Craig. Following the meeting, the Company
notified Modtech in writing of its receipt of the Acquisitor Proposal and the
indication of interest from Coachmen.

     On July 14, 2000, Mr. Craig received a memorandum from Modtech's legal
counsel requesting an extension of the termination date of the letter agreement
from July 17, 2000 to July 24, 2000.

     On July 17, 2000, the Company Board held a meeting at which it decided not
to extend the letter agreement based on the fact that Modtech had not yet
obtained a commitment for financing its purchase of the Company's Shares and
that the parties had been unable to reach a definitive agreement on certain
material terms and conditions of the merger. However, the Company Board agreed
to continue to negotiate with Modtech toward a definitive merger agreement. The
Company Board also received an update as to the status of the potential sale of
the Company from Mr. Craig as well as a report on the negotiations with respect
to, and the legal status of, the proposed transaction with Modtech from the
Company's legal counsel. In addition, the Company Board created an Investment
Committee, comprised of Kenneth Granat, as chairman, Myron Noble and David
Padden, to participate in negotiations with respect to the sale of the Company.
The Company Board also decided to commence an open bidding process between
Modtech, Acquisitor and

                                       14
<PAGE>   23

Coachmen pursuant to which each bidder would be asked to submit a firm offer
without a financing condition on or prior to July 28, 2000.

     The Investment Committee met immediately following the Company Board
meeting on July 17, 2000 and discussed implementation of the bidding process.

     Later in the day on July 17, 2000, the Company Board received a letter from
Coachmen with a further indication of interest in acquiring all of the Company's
outstanding equity interests at a price of $8.50 to $9.00 per Share subject to
certain conditions.

     Between July 18 and July 31, representatives of the Company and members of
the Investment Committee continued to engage in discussions with Messrs. Stout
and James E. Jack, the Executive Vice President and Chief Financial Officer of
Coachmen, Duncan Soukup, a principal of Acquisitor, and Mr. Gruber, of Modtech.

     On July 21, 2000, the Company terminated its letter agreement with Modtech
based on Modtech's failure to obtain financing for the transaction and the
inability of the parties to reach a definitive agreement on certain material
terms and conditions of the merger. However, the Company confirmed that it was
continuing to engage in negotiations with Modtech toward a mutually acceptable
definitive agreement of merger.

     On July 28, 2000, the Company received a written indication of interest
from Coachmen to acquire all of the outstanding shares of the Company for a cash
price of $8.75 to $9.00 per Share, subject to certain conditions, including due
diligence.

     On July 31, 2000, the Investment Committee met to discuss the status of,
and plans for continuing, negotiations with Modtech, Acquisitor and Coachmen.
The Company Board then met to hear reports from Mr. Craig and the Investment
Committee on the status of negotiations with all three potential acquirors. The
Company Board also heard reports on Mr. Craig's discussions with Modtech and
Coachmen and Mr. Granat's discussions with Acquisitor. The Company Board then
agreed with the Investment Committee's suggestion that Messrs. Craig and Noble
should meet with Coachmen.

     Between August 1, 2000 and August 21, 2000, Mr. Craig, the Investment
Committee, and legal counsel for the Company continued to discuss terms of a
potential transaction with Messrs. Stout and Jack and other representatives of
Coachmen, and with Mr. Gruber of Modtech. The Company also continued discussions
with Morgan Keegan.

     The Investment Committee held a telephonic meeting on August 3, 2000, which
was also attended by Mr. Craig and Mr. Karchmer. At such meeting, Mr. Granat
stated that Acquisitor was waiting for Coachmen's offer, Coachmen would make a
definitive offer by August 23 and Modtech was prepared to go forward with a
merger conditioned on the resolution of certain outstanding issues. The
Investment Committee decided to press Coachmen for its offer and to continue
negotiating with Modtech, including determining whether Modtech had obtained a
commitment for financing the purchase of the Company's outstanding Shares.

     During its next meeting held on August 22, 2000, the Company Board received
from Coachmen the Offer, together with a form of Merger Agreement. At the
meeting, the Company Board also received presentations from Mr. Craig, with
respect to the status of negotiations with Coachmen and Modtech, and Mr. Granat,
with respect to the status of negotiations with Acquisitor. Mr. Granat reported
that although Acquisitor had continued to engage in discussions with the Company
during the past several weeks, it had never performed due diligence or submitted
a firm offer to acquire the Company and had opted not to submit any such offer
after being advised of the proposal from Coachmen. The Company Board also heard
from the Company's legal and financial advisors regarding the Offer, the Merger
and the principal terms and conditions of Merger Agreement, including the
nonsolicitation and termination fee provisions thereof.

     Mr. Karchmer delivered Morgan Keegan's oral opinion to the Company Board
that, as of such date, the consideration to be received by the holders of Shares
of the Company's Common Stock pursuant to the Offer and the Merger as
contemplated by the Merger Agreement was fair, from a financial point of view,
to such

                                       15
<PAGE>   24

holders (and such oral opinion was subsequently confirmed by delivery of the
written opinion of Morgan Keegan, dated August 22, 2000).

     Based on such presentations, the Company Board determined at the August 22,
2000 meeting that the Merger Agreement and the transactions contemplated
thereby, including the Offer and the Merger, were fair to, and in the best
interests of, the Company's stockholders, approved the Merger Agreement and the
transactions contemplated by the Merger Agreement, including the Offer and the
Merger, and unanimously resolved to recommend that the Company's stockholders
accept the Offer and tender their Shares thereunder and, if required by
applicable law, approve and adopt the Merger Agreement and the Merger.

     The Company Board then authorized legal counsel to draft an acceptance of
Coachmen's offer, dated August 22, 2000, which reflected certain changes agreed
to orally between the parties during discussions that had taken place that day.

     On August 22, 2000, Mr. Craig notified Mr. Gruber that the Company had
entered into an agreement with Coachmen with respect to the Offer. Mr. Gruber
responded that Modtech intended to hold the Company liable for payment of the $1
million termination fee pursuant to the June 9, 2000 letter agreement between
the parties. On the same day, the Company filed a Complaint for Declaratory
Judgment in the Elkhart Superior Court No. 2, in the State of Indiana requesting
the Court's declaration that (i) the Company properly terminated its letter
agreement with Modtech and that it had no obligation to pay the $1 million or
any other amount to Modtech; and (ii) Modtech was responsible to reimburse the
Company for all of the Company's reasonable fees and expenses.

     Between August 22 and August 31, 2000, the Company and Coachmen continued
to negotiate minor changes to the Merger Agreement. On August 31, 2000, the
Merger Agreement was executed by Coachmen, Parent, the Purchaser and the
Company.

     On September 7, 2000, Modtech filed a Complaint against the Company in the
Court of Chancery of the State of Delaware in and for New Castle County
requesting damages from the Company in connection with the termination of the
merger negotiations between Modtech and the Company, together with a judicial
declaration that Modtech did not breach its letter agreement with the Company or
discharge the Company's obligations thereunder, including payment of the $1
million termination fee, and that Modtech is entitled to payment of such fee. In
addition, Modtech requested that the Court order the Company to promptly
consummate a merger with Modtech at a price of $8.05 per Share and restrain the
Company from taking any action in furtherance of the consummation of the
transaction with Coachmen, Parent and the Purchaser.

     On September 20, 2000, Coachmen and Purchaser commenced the Offer.

Agreement, a copy of which is filed as an exhibit to the Tender Offer Statement

to Purchase -- "Certain Information Concerning the Company." Capitalized terms
used in the following summary and not otherwise defined in this Offer to
Purchase shall have the meanings set forth in the Merger Agreement.

     The Offer. The Merger Agreement provides for the making of the Offer.
Purchaser has agreed to, upon the terms and subject to the satisfaction or
waiver of the Minimum Condition and the other conditions of the Offer, as set
forth in Section 15 of this Offer to Purchase -- "Certain Conditions of the
Offer," to purchase all Shares validly tendered and not withdrawn. Coachmen will
provide Purchaser with the funds to permit Purchaser to purchase the Shares. The
Merger Agreement provides that, unless previously approved by the Company in
writing, Purchaser will not make any change in the terms and conditions of the
Offer that

                                       16

(i) decreases the Offer Price, (ii) changes the form of consideration to be paid
in the Offer, (iii) reduces the maximum number of Shares to be purchased in the
Offer, (iv) imposes additional conditions to the Offer other than those provided
in the Merger Agreement, (v) amends the conditions of the Offer to broaden the
conditions, (vi) extends the Offer except as provided in the Merger Agreement,
or (vii) amends the Minimum Condition.

     The Merger Agreement also provides that without the consent of the Company
Board, Parent may cause Purchaser to extend the Offer (i) if at the Initial
Expiration Date any of the conditions to the Offer have not been satisfied or
waived (other than the Minimum Condition), until such time as the conditions are
satisfied or waived, (ii) for any period required by any rule, regulation,
interpretation or position of the SEC applicable to the Offer, or (iii) by
including a Subsequent Offering Period that would extend the Offer for an
aggregate period not to exceed 20 business days if all of the conditions to the
Offer are satisfied or waived but the number of Shares validly tendered and not
withdrawn is less than 90% of the then outstanding number of Shares on a fully
diluted basis. In the event that Purchaser includes a Subsequent Offering
Period, Purchaser must accept and promptly pay for all securities tendered prior
to the date of the extension and must otherwise meet the requirements of Rule
14d-11 under the Exchange Act in connection with each extension.

     Directors. The Merger Agreement provides that promptly upon the purchase
and payment by Purchaser of Shares pursuant to the Offer following the Initial
Expiration Date, or any extended expiration date of the Offer (the "Tender Offer
Purchase Time"), and from time to time thereafter, if the Minimum Condition has
been met, Parent will be entitled to designate that number of directors (rounded
up to the next whole number) on the Company Board that will give Parent
representation on the Company Board equal to the product of (i) the total number
of Directors on the Company Board (giving effect any increase in the number of
directors pursuant to the Merger Agreement) and (ii) the percentage that the
number of Shares purchased bears to the total number of Shares outstanding on a
fully diluted basis. Under the terms of the Merger Agreement the Company has
agreed, upon Parent's request, to either promptly increase the size of the
Company Board or secure the resignation of the necessary number of directors so
that Parent's designees are elected to the Company Board and constitute at all
times after the Tender Offer Purchase Time a majority of the Company Board. The
Company will cause persons designated by Purchaser to constitute at least the
same percentage as is on the Company Board of each committee of the Company
Board (other than any committee of the Company Board established to take action
under the Merger Agreement). The Company's obligation to appoint designees to
the Board is subject to Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder.

     The Merger. The Merger Agreement provides that, subject to the terms and
conditions of the Merger Agreement, at the Effective Time Purchaser will be
merged with and into the Company. Following the Merger, the Company will
continue as the surviving corporation (the "Surviving Corporation") and the
separate corporate existence of Purchaser will cease. The Merger Agreement
further provides that the closing of the Merger will take place no later than
the second business day after satisfaction or waiver of the conditions to the
Merger. At the closing the Company will file the necessary documents with
Delaware public officials to make the Merger effective.

     Pursuant to the Merger Agreement the Company has agreed that it will (i)
take all actions necessary under the DGCL to duly call, give notice of, convene
and hold a meeting of its stockholders as promptly as reasonably practicable
following acceptance for payment and payment for the Shares for the purpose of
considering and voting upon the adoption of the Merger Agreement, (ii) promptly
prepare and file with the SEC a proxy statement for the solicitation of a vote
of the Company's stockholders to be held in connection the Merger (the "Proxy
Statement") that will include (A) the recommendation of the Company Board that
stockholders of the Company vote in favor of the approval and adoption of the
Merger Agreement and (B) the written opinion of the financial advisor that the
consideration to be received by the stockholders of the Company pursuant to the
Merger Agreement is fair to the stockholders from a financial point of view, and
(iii) use all reasonable efforts to (A) have the Proxy Statement cleared by the
SEC as promptly as practicable after filing, and (B) promptly mail the Proxy
Statement to the stockholders of the Company. At the meeting, Parent and
Purchaser have agreed to vote all Shares purchased pursuant to the Offer and all
Shares owned by them or any subsidiary of Parent in favor of the Merger
Agreement.
                                       17
<PAGE>   26

     The Merger Agreement further provides that if Parent, Purchaser and any
other subsidiary of Parent acquires at least 90% of the outstanding Shares, the
Company, Parent and Purchaser will take all necessary and appropriate action to
cause the Merger to become effective as soon as practicable after the expiration
of the Offer without a meeting of the stockholders of the Company in accordance
with Section 253 of the DGCL.

     Charter, Bylaws, Directors and Officers. The Certificate of Incorporation
of Purchaser in effect at the Effective Time will be the Certificate of
Incorporation of the Surviving Corporation until amended. The bylaws of
Purchaser in effect at the Effective Time will be the bylaws of the Surviving
Corporation until amended. The directors of Purchaser at the Effective Time will
be the initial directors of the Surviving Corporation and will hold office in
accordance with the Certificate of Incorporation and bylaws of the Surviving
Corporation until their respective successors are duly elected or appointed and
qualified. The officers of Purchaser at the Effective Time will be the initial
officers of the Surviving Corporation and will hold office in accordance with
the Certificate of Incorporation and bylaws of the Surviving Corporation until
their respective successors are duly elected or appointed and qualified.

     Conversion of Shares. At the Effective Time, each Share, issued and
outstanding immediately prior to the Effective Time (excluding Shares held in
the Company's treasury or any of its subsidiaries and Shares held by Parent,
Purchaser or any subsidiary of Parent) will by virtue of the Merger and without
any action by Purchaser, be converted into and become the Merger Consideration.
At the Effective Time each Share of the Company held in the treasury and each
Share held by Parent, Purchaser or any subsidiary of Parent, Purchaser or the
Company will, without any action by Parent, Purchaser, the Company or the holder
thereof, be canceled, retired and cease to exist and no Merger Consideration
will be delivered with respect thereto. At the Effective Time, each share of
common stock of Purchaser outstanding at the Effective Time will be converted
into one share of common stock of the Surviving Corporation.

     Company Stock Options. At the Effective Time, each option to purchase
Shares (a "Stock Option" or collectively "Stock Options") granted under the
Company's 1991 Stock Option Plan, the 1994 Stock Option Plan or the 1997 Stock
Option Plan (each a "Company Plan" or collectively the "Company Plans") which is
then outstanding and unexercised, which Company Stock Options total 578,009 as
of August 23, 2000, will cease to represent a right to acquire Shares and will
automatically convert into options to purchase shares of common stock of
Coachmen, and Coachmen will assume such options (each an "Assumed Option")
subject to the terms of the applicable Company Plan, in each case as heretofore
amended or restated, as the case may be, and the agreement evidencing the grant
of each Assumed Option, provided however, that from and after the Effective
Time, the per share exercise price of each Assumed Option will be adjusted in
accordance with Schedule 2.11 of the Merger Agreement (the "Exchange Exercise
Price"), on and after the Effective Time.

     The Merger Agreement provides that the exercise price, the number of shares
of Coachmen common stock purchasable upon exercise and the other terms and
conditions of exercise of any Assumed Options that are "incentive stock options"
(as defined in Section 422 of the Code), will be determined in order to comply
with Section 424(a) of the Code. The number of shares purchasable upon exercise,
duration and other terms of any Assumed Option will be the same as the original
Stock Option except that all references to the Company will be deemed references
to Coachmen. Parent acknowledges and agrees that all Assumed Options shall be
fully vested as set forth in the Option agreements. The terms of each Assumed
Option will, according to its terms, be subject to further adjustment as
appropriate to reflect any stock split, stock dividend, recapitalization or
other similar transaction with respect to Coachmen common stock on or after the
Effective Time. Prior to the Effective Time, the Company plan committee shall
adopt a resolution approving the assumption procedure for Stock Options
described in the Merger Agreement.

     The Company has agreed to take all action necessary at or before the
Effective Time to provide that, as of the Effective Time, all other options,
warrants or other rights to purchase Shares that are not issued pursuant to a
Company Plan will be terminated.

     Pursuant to the Merger Agreement, Coachmen has agreed to reserve for
issuance a sufficient number of Coachmen common stock for delivery upon the
exercise of Assumed Options. Coachmen shall take all action necessary to
register the Coachmen common stock subject to the Assumed Options under the
Securities Act
                                       18
<PAGE>   27

of 1933, as amended (the "Securities Act"), on a Form S-8 registration statement
no later than 30 days after the Effective Time, and to cause the effectiveness
of the registration statement and the current status of the prospectus for so
long as the Assumed Options remain outstanding.

     Representations and Warranties. The Merger Agreement contains customary
representations and warranties of the parties. These include representations and
warranties of the Company with respect to, among other things, organization and
qualification, capitalization, subsidiaries, authority, SEC filings, financial
statements, governmental approvals, compliance with laws, employee benefits,
litigation, intellectual property, employment matters, tax matters, insurance,
environmental matters, business matters and property. The Merger Agreement also
contains customary representations and warranties of Coachmen, Parent and
Purchaser, including among other things, organization and qualification,
authority, governmental approvals and litigation. The representations and
warranties contained in the Merger Agreement expire at the Effective Time of the
Merger.

     Conduct of Company Business Pending the Merger. From the date of the Merger
Agreement until the Effective Time, the Company will, and will cause each of its
subsidiaries to, conduct its operations in the ordinary course of business
consistent with past practice and use all commercially reasonable efforts to
preserve intact its current business organizations, keep available the service
of its current officers and employees and preserve its relationships with
customers, suppliers, distributors, lessors, creditors, employees, contractors
and others having business dealings with the Company. Prior to the Effective
Time, neither Company nor any of its subsidiaries will, without Parent's written
consent: (i) alter its corporate formalities or the amount of authorized and
issued stock, except with regard to Company Stock Options; (ii) alter the
corporate structure of the Company or its subsidiaries; (iii) incur, assume or
become liable for any indebtedness, except in the ordinary course of business;
(iv) alter the terms of any salary, compensation, benefits, severance or

intellectual property, accounting principles (except as required by law),
valuation of assets (other than in the ordinary course of business), material
contracts, warranty terms, capital expenditures, or manufacturing capacity
expenditures; (vi) make any material tax election or failure to file any tax
returns or pay any taxes or material debts; or (vii) settle or compromise any
pending or threatened lawsuit that is material or relates to the Offer or the
Merger, among other things.

     No Solicitation or Negotiation. Under the Merger Agreement, the Company
agreed that it, its subsidiaries and other affiliates and their respective
officers and other employees with managerial responsibilities, directors,
representatives and agents, including the Company's financial advisor,
investment banker, attorneys and accountants, will immediately cease any
discussions or negotiations with any other person with respect to any Third
Party Acquisition (as defined below). The Merger Agreement further provides that
the Company and its subsidiaries will not authorize or permit their respective
officers, directors, employees, representatives or agents to, directly or
indirectly, encourage, solicit, participate in or initiate discussions or
negotiations with anyone (other than Parent, Purchaser or their designees)
concerning any Third Party Acquisition. However, if the Company Board determines
in good faith that it is required to do so by applicable law, the Company may
furnish information in response to an unsolicited proposal, offer or indication
of interest from a third party and participate in discussions or negotiations
with such third party provided that the Company Board reasonably determines that
the third party is reasonably capable of consummating a Superior Proposal (as
defined below). Prior to furnishing such information, the Company must enter
into a customary confidentiality agreement.

     The Company Board may not withdraw or modify its recommendation of the
transactions contemplated by the Merger Agreement, or approve or recommend, or
cause or permit the Company to enter into, any agreement with respect to any
Third Party Acquisition, unless, prior to the Tender Offer Purchase Time, (i)
the Company Board by a majority vote determines in its good faith judgment,
after consultation with its legal counsel, that it is required to do so in order
to comply with its fiduciary duties under applicable law and (ii) provides
Parent with written notice of the Superior Proposal which is not followed by an
offer from Parent within two business days of receipt of such notice that the
Company Board by a majority vote determines in its good faith judgment, based on
the advice of its financial advisor, to be at least as favorable to the
Company's
                                       19
<PAGE>   28

stockholders as the Superior Proposal. The Company may not enter into any
agreement with respect to a Superior Proposal unless and until the Merger
Agreement is terminated by its terms and the Company has paid Parent all amounts
due under the Merger Agreement. At and after the Tender Offer Purchase Time, the
Company Board may not under any circumstances withdraw its recommendation of the
transactions contemplated by the Merger Agreement or approve or recommend, or
cause the Company to enter into any agreement with respect to, any Third Party
Acquisition.

     The Merger Agreement also requires the Company to notify Parent promptly,
and in any event within one business day after becoming aware thereof, in the
event the Company, any of its subsidiaries and affiliates or any of their
respective directors, officers, employees and agents receive any proposal or
inquiry concerning a Third Party Acquisition, including the terms and conditions
thereof and the identity of the party submitting the proposal.

Parent, Purchaser or any affiliate thereof (a "Third Party"), (ii) the
acquisition by a Third Party of 15% or more of the assets of the Company and its
subsidiaries, taken as a whole, other than the sale of its products in the
ordinary course of business consistent with past practice, (iii) the acquisition
by a Third Party of 15% or more of the issued and outstanding Shares, or (iv)
the adoption by the Company of a plan of liquidation or the declaration or
payment of an extraordinary dividend.

     The term "Superior Proposal" is defined in the Merger Agreement as any bona
fide proposal to acquire directly or indirectly for consideration consisting of
solely cash and/or securities all of the Shares then outstanding or all or
substantially all the assets of the Company that, (i) the Company Board by a
majority vote determines in its good faith judgment (based on the consultation
with a financial advisor) is financeable and on terms that are more favorable to
the Company's stockholders than the Offer and the Merger, (ii) the Company Board
by a majority vote determines in its good faith judgment (following and based on
consultation with a financial advisor) is reasonably capable of being completed,
(iii) does not contain a right of first refusal or similar provision with
respect to any counter-proposal by Parent, and (iv) does not contain any
financing or due diligence conditions.

     Access to Information. The Merger Agreement provides that from the date of
the Merger Agreement to the Effective Time, upon reasonable notice the Company
will (i) give Parent and its representatives reasonable access during normal
business hours to all employees, plants, offices, warehouses, and other
facilities and to all books, records, and personnel files of current employees
of the Company and its subsidiaries, and (ii) cause its officers and the
officers of its subsidiaries to furnish Parent with financial and operating data
and other information with respect to the business and properties of the Company
and its subsidiaries. Parent will, upon the Company's request, make available a
designated officer of Parent to answer questions and provide information
regarding Parent and its subsidiaries to the Company. Between the date of the
Merger Agreement and the Effective Time, the Company additionally has agreed to
furnish to Parent certain monthly, quarterly and annual financial information.

     All information provided either by Parent to the Company or by the Company
to Parent, including the consultants and advisors of each, will be kept
confidential in accordance with the confidentiality provisions of the Standard
Mutual Nondisclosure Agreement between Coachmen and the Company dated July 13,
2000.

     Certain Filings; Reasonable Efforts. Pursuant to the Merger Agreement, each
of Parent, Purchaser and the Company has agreed to use all reasonable efforts to
consummate the transactions contemplated by the Merger Agreement, including all
reasonable efforts to, (i) cooperate in the preparation and filing of disclosure
documents, any filings that may be required under the HSR Act or any filings
under similar foreign regulations, (ii) obtain consents of third parties and
governmental entities, (iii) contest any legal proceeding relating to the
Merger, and (iv) execute any additional documents necessary to consummate the
Offer and the Merger. The Company also has agreed to use all reasonable efforts
to encourage its employees to continue employment with the Company and the
Surviving Corporation after the Effective Time.

                                       20
<PAGE>   29

     Parent, Purchaser and the Company have agreed to consult and cooperate with
one another and consider in good faith the views of one another, in connection
with any proceedings under or relating to the HSR Act or any foreign, federal,
or state antitrust, competition or fair trade law.

     Public Announcements. The Merger Agreement provides that Coachmen, Parent,
Purchaser and the Company will not issue any press release or make any public
statements with respect to the Merger Agreement, including the Merger or any
Third Party Acquisition, without the prior consent of the others, except to the
extent that such disclosure may be required by applicable law or by the rules
and regulations of, or any agreements with, the Nasdaq National Market or
following a change, if any, of the Company Board's recommendation of the Merger.

     Indemnification; Directors' and Officers' Insurance. The Merger Agreement
provides that, from and after the Effective Time, Parent and the Surviving
Corporation will indemnify, defend and hold harmless all Indemnified Parties (as
defined below) against all losses, expenses, claims, damages or liabilities
arising out of actions or omissions occurring on or prior to the Effective Time
(including transactions contemplated by the Merger Agreement) to the fullest
extent provided by Coachmen governing instruments and applicable law. Coachmen,
Parent and the Surviving Corporation will provide indemnification only to the
extent that any directors' and officers' liability insurance policy of Coachmen
or its subsidiaries does not provide coverage and actual payment with respect to
matters that would otherwise be subject to indemnification. The term
"Indemnified Parties" includes all present or former directors and officers of
the Company or any of its subsidiaries.

     Parent and the Surviving Corporation's obligation to provide
indemnification will in no event exceed the Company's net worth as of June 30,
2000. Parent and the Surviving Corporation will maintain for a period of not
less than six years after the Effective Time the current policies of directors'
and officers' liability insurance maintained by the Company or its subsidiaries,
to the extent such insurance is available at a premium of no more than three
times the premium immediately prior to the Effective Time, provided that (i)
Coachmen, Parent or the Surviving Corporation may substitute policies, or at
Coachmen's election cause coverage to be provided under any policy maintained
for the benefit of Coachmen, of at least the same coverage containing terms and
conditions that are no less advantageous to the Indemnified Parties and (ii)
neither Coachmen, Parent nor the Surviving Corporation shall be required to
provide insurance in excess of that provided under the Company's current
policies of directors' and officers' insurance.

     Notification of Certain Matters. Each of the Company and Parent has agreed
to give one another prompt notice of the occurrence or nonoccurrence of any
event that has caused or would be likely to cause any representation or warranty
to be untrue or inaccurate or any condition or agreement contained in the Merger
Agreement not to be complied with or satisfied in all material respects.

     Company Compensation and Benefit Plans. Pursuant to the Merger Agreement,
the Company has agreed to take all actions necessary to amend, merge, freeze or
terminate all Company compensation and benefit plans, upon written request by
Parent.

permit the consummation of the transactions contemplated by the Merger
Agreement, the Offer or the Merger and (ii) otherwise act to eliminate or
minimize the effects of such statutes and regulations promulgated thereunder on
the transactions.

required by law, approval of the transactions contemplated by the Merger
Agreement by the requisite vote of stockholders; (ii) Purchaser's acceptance for

      States governmental body of competent jurisdiction shall have issued a

      decree, ruling or other action is or shall have become nonappealable, or
      (B) the Merger shall not have been consummated by December 15, 2000 (the

      Agreement under clause (B) of this paragraph is not available to any party
      whose failure to fulfill any obligation under the Merger Agreement shall
      have been a principal reason that the Effective Time did not occur on or

(iii) the Company if (A) there shall have been a breach of any representations

      material obligations under the Merger Agreement, (B) there shall have been
      a breach of any covenants or agreements by the Company that has a material

     Fees and Expenses. The Merger Agreement provides that the Company will pay
a $2 million fee (the "Fee") to Parent if the Merger Agreement is terminated
pursuant to:

(1) paragraph (iii)(D) or paragraphs (iv)(C), (D) or (E) above;

(2) paragraphs (iv)(A) or (B) above, and, at the time of termination, there is a
    third party offer outstanding to consummate, or a third party has publicly
    announced and not withdrawn a plan or proposal with respect to, a Third
    Party Acquisition and such Third Party Acquisition occurs or there is no
    third party offer outstanding or plan or proposal announced but within 12
    months after the date on which the Merger Agreement has been terminated the
    Company enters into an agreement with respect to a Third Party Acquisition
    or a Third Party Acquisition occurs involving any person other than Parent
    or one of its subsidiaries; or

(3) paragraph (vi) above, and, at the time of such termination, there is a third
    party offer outstanding to consummate, or a third party shall have publicly
    announced and not withdrawn a plan or proposal with respect to, a Third
    Party Acquisition and the Company has entered into an agreement with respect
    to such Third Party Acquisition or such Third Party Acquisition otherwise
    occurs within 12 months after the date on which the Merger Agreement has
    been terminated; and Parent and Purchaser would suffer direct and
    substantial damages, which damages cannot be determined with reasonable
    certainty.

     The Fee is payable to Parent within three business days of the occurrence
of any of the events described in paragraphs (1) through (3) above as liquidated
damages. If Parent or Purchaser receives the Fee they shall not assert or pursue
any claim or cause of action against the Company or any of its affiliates,
officers, directors, representatives or agents based on the Merger Agreement.

     Parent has agreed to promptly pay or reimburse the Company for all costs,
fees and expenses incurred by the Company or on its behalf in connection with
the Merger Agreement, the Offer and the Merger (including fees payable to
investment bankers, counsel and accountants). Purchaser shall pay a $1,000,000
fee to the Company if the transaction contemplated by this Agreement fails to
close due to a breach of a material obligation under this Agreement by Coachmen,
Parent, or Purchaser in any material respect, unless the Company shall have
breached any of its material obligations hereunder in any material respect.
Except as otherwise specifically provided in Section 7.3 of the Merger Agreement
"Fees and Expenses," each of the Parent and the Company has agreed to bear their
own expenses in connection with the Merger Agreement and related transactions.

     Amendment. The Merger Agreement may be amended by the Company, Parent and
Purchaser at any time before or after approval of the Merger by the stockholders
of the Company, but once stockholders of the Company have approved the Merger
Agreement no amendment that requires stockholder approval under applicable law
may be made without obtaining such approval.

     Extension; Waiver. At any time prior to the Effective Time, each of Parent,
Purchaser and the Company may (i) extend the time for the performance of any of
the obligations or other acts of any other party, (ii) waive any inaccuracies in
the representations and warranties of any other party, or (iii) waive compliance
by any other party with respect to the agreements or conditions contained in the
Merger Agreement.

GOING PRIVATE TRANSACTIONS.

     The Merger would have to comply with any applicable federal law operative
at the time of its consummation including Rule 13e-3 under the Exchange Act
which applies to certain "going private" transactions. If applicable, Rule 13e-3
requires, among other things, that certain financial information concerning the
fairness of the Merger and the consideration offered to minority stockholders in
the Merger be filed with the SEC and disclosed to stockholders prior to the
consummation of the Merger. Purchaser does not believe that Rule 13e-3 will be
applicable to the Merger unless the Merger is consummated more than one year
after the termination of the Offer.

EMPLOYMENT AGREEMENTS.

     The Company currently has an employment agreement with Mr. Craig (the
"Craig Agreement") which is described more fully in the Company's proxy
statement filed with the SEC on November 21, 1999 (the "Company's Proxy
Statement"). The summary description of the Craig Agreement contained in the
Company's Proxy Statement is filed as Exhibit (d)(3) to the Schedule TO and
incorporated herein by reference. At or prior to the Effective Time, the Company
shall amend the Craig Agreement to include provisions regarding annual salary,
Deferred Compensation Plan interests, and expiration of Stock Options. Parent
and Purchaser intend to honor all terms and conditions of the Craig Agreement
and Mr. Craig is expected to continue his employment with the Surviving
Corporation following the completion of the Offer and the Merger.

     The Company and Coachmen have entered into modified employment agreements
with the following key employees: Dean Bagg, Richard Bedell, Daniel Berdahl,
Edward Bollero, John Catalino, Thomas Martini, James Metzler, Neal Moss, Michael
Ploutz, Donald Selke, Rob Winks and Rodney Young, to be effective as of the
Effective Time.

12. PURPOSE OF THE OFFER AND THE MERGER; PLANS FOR THE COMPANY; OTHER MATTERS

     Purpose of the Offer and the Merger. The purpose of the Offer and the
Merger is to acquire control of, and the entire equity interest in, the Company.
The Offer is being made pursuant to the Merger Agreement and is intended to
increase the likelihood that the Merger will be effected. The purpose of the
Merger is to acquire all outstanding Shares not tendered and purchased pursuant
to the Offer. If the Offer is successful, Purchaser intends to consummate the
Merger as soon as practicable following the satisfaction or waiver of each of
the conditions to the Merger set forth in the Merger Agreement.

     Stockholders of the Company who sell their Shares in the Offer will cease
to have any equity interest in the Company and any right to participate in its
earnings and future growth. If the Merger is consummated, non-tendering
stockholders will no longer have an equity interest in the Company and instead
will have only the right to receive cash consideration pursuant to the Merger
Agreement or to exercise statutory appraisal rights under Section 262 of the
DGCL. See Section 17 of this Offer to Purchase -- "Appraisal Rights." Similarly,
after selling their Shares in the Offer or the subsequent Merger, stockholders
of the Company will not bear the risk of any decrease in the value of the
Company.

     The primary benefits of the Offer and the merger to the stockholders of the
Company are that they are being afforded an opportunity to sell all of their
Shares for cash at a price which represents a premium of approximately 10% over
the closing sales price of the Shares on August 22, 2000, the last full trading
day prior to the initial public announcement that the Company, Coachmen,
Purchaser and Parent planned to enter into the Offer and the Merger, assuming
that the Offer Price is $8.40 per Share.

     Stockholder Approval. The Merger is subject to, among other things, the
condition that the Merger Agreement is approved and adopted, if required, by the
stockholders of the Company. If the Minimum Condition is satisfied, Purchaser
would have sufficient voting power to approve the Merger without the affirmative
vote of any other stockholder. The Company has agreed, if stockholder approval
is required, to cause a meeting of its stockholders to be held as promptly as
reasonably practicable following completion of the Offer for the purpose of
considering and taking action upon the approval and adoption of the Merger
Agreement. Parent and Purchaser have agreed (and Parent has agreed to cause
Purchaser to) vote the Shares owned by Parent, Purchaser and any other
subsidiaries of Parent in favor of the approval and adoption of the Merger
Agreement.

     Short-Form Merger. Under Section 253 of the DGCL, if a corporation owns at
least 90% of the outstanding shares of each class of another corporation, the
corporation holding such stock may merge that corporation into itself, or itself
into that corporation, without any action or vote on the part of the board of
directors or the stockholders of the other corporation (a "short-form merger").
In the event that Purchaser acquires in the aggregate at least 90% of the
outstanding Shares pursuant to the Offer, then, at the election of Parent, a
short-form merger could be effected without any further approval of the Company
Board or

                                       24
<PAGE>   33

stockholders of the Company, subject to compliance with Section 253 of the DGCL.
Even if Purchaser does not own 90% of the outstanding Shares following
consummation of the Offer, Parent or Purchaser could seek to purchase additional
Shares in any Subsequent Offering Period that may be included in the Offer, in
order to reach the 90% threshold and employ a short-form merger.

     Plans for the Company. Except as otherwise set forth in this Offer to
Purchase, it is expected that, initially following the Merger, the business
operations of the Company will be continued by the Surviving Corporation
substantially as they are currently being conducted. The Merger Agreement
provides that the directors and officers of Purchaser immediately prior to the
Effective Time will be the initial directors and officers of the Surviving
Corporation. Upon completion of the Offer and the Merger, Parent intends to
conduct a detailed review of the Company and its assets, corporate structure,
capitalization, operations, policies, properties, management and personnel.
After such review, Parent will determine what actions or changes, if any, would
be desirable in light of the circumstances which then exist.

     Assuming the Minimum Condition is satisfied and Purchaser purchases and
pays for Shares pursuant to the Offer, Parent intends to promptly exercise its
rights under the Merger Agreement to obtain majority representation on, and
control of, the Company Board. The Merger Agreement provides that, upon the
purchase of and payment for any Shares by Purchaser pursuant to the Offer,
Parent will be entitled to designate that number of directors, rounded up to the
next whole number, on the Company Board equal to the product of (i) the total
number of Directors on the Company Board (giving effect to any increase in the
number of directors pursuant to the Merger Agreement), and (ii) the percentage
that the number of Shares purchased bears to the total number of Shares
outstanding on a fully-diluted basis. See Section 11 of this Offer to
Purchase -- "The Merger Agreement; Other Arrangements."

     Except as described in this Offer to Purchase, neither Parent nor Purchaser
has any present plans or proposals that would relate to or result in (i) any
extraordinary corporate transaction, such as a merger, reorganization or
liquidation involving the Company or any of its subsidiaries, (ii) a sale or
transfer of a material amount of assets of the Company or any of its
subsidiaries, (iii) any change in the Company Board or management, (iv) any
material change in the Company's capitalization or dividend policy, (v) any
other material change in the Company's corporate structure or business, (vi) a
class of securities being delisted from a national securities exchange or
ceasing to be authorized to be quoted in an inter-dealer quotation system of a
registered national securities association or (vii) a class of equity securities
of the Company becoming eligible for termination of registration pursuant to
Section 12(g) of the Exchange Act.

13. CERTAIN EFFECTS OF THE OFFER

     Market for the Shares. The purchase of Shares pursuant to the Offer will
reduce the number of Shares that might otherwise trade publicly, could reduce
the number of holders of Shares and, depending upon the number of Shares so
purchased, could adversely affect the liquidity and market value of the
remaining publicly-held Shares. Purchaser cannot predict whether the reduction
in the number of Shares that might otherwise trade publicly would have an
adverse or beneficial effect on the market price for, or marketability of, the
Shares or whether the reduction would cause future market prices to be greater
or less than the Offer Price.

     Nasdaq Listing. Depending upon the number of Shares purchased pursuant to
the Offer, the Shares may no longer meet the requirements of the National
Association of Securities Dealers, Inc. (the "NASD") for continued inclusion on
the Nasdaq National Market. According to the NASD's published guidelines, the
Shares would no longer be eligible for continued listing if, among other things,
the Company fails to have either (i) at least 750,000 publicly held shares, held
by at least 400 round-lot stockholders, with a market value of at least
$5,000,000, net tangible assets (total assets (excluding goodwill) minus
liabilities) of at least $4,000,000 and have a minimum bid price of $1, or (ii)
at least 1,100,000 publicly held shares, held by at least 400 round-lot
stockholders, with a market value of at least $15,000,000, have a minimum bid
price of $5 and have either (A) a market capitalization of at least $50,000,000
or (B) total assets and revenues each of at least $50,000,000. Shares held
directly or indirectly by an officer or director of the Company or by a
beneficial owner of more than 10% of the Shares will ordinarily not be
considered as being publicly held for purposes of

                                       25
<PAGE>   34

these standards. If the Shares were no longer eligible for inclusion in the
Nasdaq National Market, they might nevertheless continue to be included in the
Nasdaq SmallCap Market unless, among other things, the public float is less than
500,000 Shares, or there are fewer than 300 stockholders (round lot holders) in
total, or the market value of public float is less than $1 million.

     Parent currently intends to cause the Company to delist the Shares from the
Nasdaq National Market as soon as reasonably practicable after consummation of
the Offer and the Merger. If the Nasdaq National Market were to cease to publish
quotations for the Shares, it is possible that the Shares would continue to
trade in the over-the-counter market and that price or other quotations would be
reported by other sources. The extent of the public market for such Shares and
the availability of such quotations would depend, however, upon such factors as
the number of stockholders and/or the aggregate market value of such securities
remaining at such time, the interest in maintaining a market in the Shares on
the part of securities firms, the possible termination of registration under the
Exchange Act, as described below, and other factors.

     Exchange Act Registration. The Shares are currently registered under the
Exchange Act. The purchase of the Shares pursuant to the Offer may result in the
Shares becoming eligible for deregistration under the Exchange Act. Registration
of the Shares may be terminated upon application of the Company to the SEC if
the Shares are not listed on a national securities exchange and there are fewer
than 300 holders of record of the Shares. 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. Furthermore, the ability of "affiliates" of the Company
and persons holding "restricted securities" of the Company to dispose of such
securities pursuant to Rule 144 or Rule 144A promulgated under the Securities
Act, may be impaired or eliminated. Parent currently intends to cause the
Company to terminate the registration of Shares under the Exchange Act as soon
as practicable after consummation of the Offer as the requirements for
termination of registration are met. If registration of the Shares under the
Exchange Act were terminated, the Shares would no longer be "margin securities"
or be eligible for inclusion on the Nasdaq National Market.

     Margin Regulations. The Shares are currently "margin securities" under the
Regulations of the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board"), which has the effect, among other things, of allowing
brokers to extend credit on the collateral of the Shares. Depending upon factors
similar to those described above regarding the market for the Shares and stock
quotations, it is possible that, following the Offer, the Shares would no longer
constitute "margin securities" for the purposes of the margin regulations of the
Federal Reserve Board and therefore could no longer be used as collateral for
loans made by brokers.

14. DIVIDENDS AND DISTRIBUTIONS

     The Company has paid not paid dividends on its Shares during its two most
recent fiscal years. The Merger Agreement provides that from the date of the
Merger Agreement until the Effective Time, unless the Parent has consented in
writing, the Company may not declare, set aside or pay any dividends on, or make
other distributions with respect to any of the Company's capital stock, or
repurchase, redeem or otherwise acquire, any securities of the Company or any of
its subsidiaries, except as may be required under the terms of any Company Stock
Options.

15. CERTAIN CONDITIONS OF THE OFFER

     Notwithstanding any other provision of the Offer, and subject to any
applicable rules and regulations of the SEC, including Rule 14e-1(c) relating to
Purchaser's obligation to pay for or return tendered shares after termination of
the Offer, Purchaser shall not be required to accept for payment or pay for any
Shares tendered pursuant to the Offer, may delay the acceptance for payment of
any Shares, subject to the restrictions set forth in the Merger Agreement, may
amend the Offer consistent with the terms of the Merger Agreement,

                                       26
<PAGE>   35

including by extending the Offer one or more times, and may terminate the Offer,
if (i) less than a majority of the outstanding Shares on a fully-diluted basis
(including all Shares issuable upon exercise of all vested and unvested options)
has been tendered pursuant to the Offer and not withdrawn by the Expiration
Date, as it may be extended in accordance with the terms of the Offer, (ii) any
applicable waiting period under the HSR Act has not expired or been terminated
prior to the Expiration Date, or (iii) at any time after the date of the Merger
Agreement, and before acceptance for payment of any Shares, any of the following
events shall occur and be continuing:

     (a) there shall have been any action taken, or any statute, rule,
regulation, judgment, order or injunction promulgated, entered, enforced,
enacted, issued or deemed applicable to the Offer or the Merger by any domestic
or foreign court or other Governmental Entity (as defined in the Merger
Agreement) which directly or indirectly (i) prohibits, or imposes any material
limitations on, Parent's ownership or operation (or that of any of its
subsidiaries or other affiliates) of all or a material portion of its or the
Company's businesses or assets, or compels Parent or any of its subsidiaries or
other affiliates to dispose of or hold separate any material portion of the
business or assets of the Company or Parent and its respective subsidiaries, in
each case taken as a whole, (ii) prohibits, or makes illegal, the acceptance for
payment, payment for or purchase of Shares or the consummation of the Offer, the
Merger or the other transactions contemplated by the Merger Agreement, (iii)
results in the material delay in or materially restricts the ability of
Purchaser, or renders Purchaser unable, to accept for payment, pay for or
purchase some or all of the Shares, (iv) imposes material limitations on the
ability of Parent effectively to exercise full rights of ownership of the
Shares, including the right to vote the Shares purchased by it on all matters
properly presented to the Company's stockholders, or (v) otherwise has a
material adverse effect on the Company;

     (b) (i) the representations and warranties of the Company set forth in the
Merger Agreement shall not be true and correct in all material respects as of
the date of the Merger Agreement and as of consummation of the Offer as though
made on or as of such date (except for representations and warranties made as of
a specified date) but only if the respects in which the representations and
warranties made by the Company (without giving effect to any "materiality"
limitations or references to "material adverse effect" set forth therein) are
inaccurate would in the aggregate have a Material Adverse Effect (as defined in
the Merger Agreement) on the Company, (ii) the Company shall have failed to
comply with its covenants and agreements contained in the Merger Agreement in
all material respects, or (iii) there shall have occurred any events or changes
which have had or which are reasonably likely to have a Material Adverse Effect
on the Company;

     (c) it shall have been publicly disclosed or Parent shall have otherwise
learned that (i) any person or "group" (as defined in Section 13(d)(3) of the
Exchange Act) shall have acquired or entered into a definitive agreement or
agreement in principle to acquire beneficial ownership of more than 20% of the
Shares or any other class of capital stock of the Company, through the
acquisition of stock, the formation of a group or otherwise, or shall have been
granted any option, right or warrant, conditional or otherwise, to acquire
beneficial ownership of more than 20% of the Shares and (ii) such person or
group shall not have tendered such Shares pursuant to the Offer;

     (d) the Company Board shall have withdrawn, or modified or changed in a
manner adverse to Parent and Purchaser (including by amendment of the Schedule
14D-9), its recommendation of the Offer, the Merger Agreement or the Merger, or
recommended another proposal or offer, or the Company Board shall have resolved
to do any of the foregoing;

     (e) the Merger Agreement shall have terminated in accordance with its
terms;

     (f) there shall have occurred (i) any general suspension of trading in, or
limitation on prices for, securities on the New York Stock Exchange or the
Nasdaq National Market, for a period in excess of twenty-four (24) hours, (ii)
the commencement of a war, armed hostilities or other national or international
calamity directly or indirectly involving the United States that has had or is
reasonably likely to have a Material Adverse Effect on the Company or materially
adversely affect or delay the consummation of the Offer, (iii) a declaration of
a banking moratorium or any suspension of payments in respect of banks in the
United States (whether or not mandatory), (iv) any limitation (whether or not
mandatory) by any United States
                                       27
<PAGE>   36

Governmental Entity on the extension of credit by banks or other financial
institutions, (v) a change in general, financial, bank or capital market
conditions which materially and adversely affects the ability of financial
institutions in the United States to extend credit or syndicate loans, or (vi)
in the case of any of the foregoing existing at the time of the commencement of
the Offer, a material acceleration or worsening thereof;

which in the good faith judgment of Parent, in any such case, and regardless of
the circumstances (including any action or inaction by Parent) giving rise to
such condition makes it inadvisable to proceed with the Offer or the acceptance
for payment of or payment for the Shares.

     The conditions set forth above are for the sole benefit of Parent and
Purchaser and may be waived by Parent and Purchaser, in whole or in part at any
time and from time to time, in the sole discretion of Parent and Purchaser. The
failure by Parent and 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.

16. CERTAIN LEGAL MATTERS; REGULATORY APPROVALS

     General. Purchaser is not aware of any material pending legal proceeding
relating to the Offer. Based on its examination of publicly available
information filed by the Company with the SEC and other publicly available
information concerning the Company, Purchaser is not aware of any governmental
license or regulatory permit that appears to be material to the Company's
business that might be adversely affected by Purchaser's purchase of the Shares
as contemplated herein or, except as set forth below, of any approval or other
action by any government or governmental, administrative or regulatory authority
or agency, domestic or foreign, that would be required for the purchase or
ownership of Shares by Purchaser or Parent as contemplated herein. Should any
such approval or other action be required, Purchaser currently contemplates
that, except as described below under "State Takeover Statutes," such approval
or other action will be sought. While, except as otherwise described in this
Offer to Purchase, Purchaser does not presently intend to delay the acceptance
for payment of, or payment for, Shares tendered pursuant to the Offer pending
the outcome of any such matter, there can be no assurance that any such approval
or other action, if needed, would be obtained without substantial conditions or
that if such approval were not obtained or such other action were not taken,
adverse consequences might not result to the Company's business, or certain
parts of the Company's business might not have to be disposed of, any of which
could cause Purchaser to elect to terminate the Offer without the purchase of
Shares thereunder under certain conditions. See Section 15 of this Offer to
Purchase -- "Certain Conditions of the Offer."

     State Takeover Statutes. The Company is incorporated under the laws of
Delaware. Section 203 of the DGCL ("Section 203"), in general, prevents an
"interested stockholder" (including a person who owns or has the right to
acquire 15% or more of the corporation's outstanding voting stock) from engaging
in a "business combination" (defined to include mergers and certain other
actions) with a Delaware corporation for a period of three years following the
date such person became an interested stockholder. The Company Board has taken
all appropriate action so that neither Parent nor Purchaser is or will be
considered an "interested stockholder" pursuant to Section 203.

     Other than as set forth above, Parent and Purchaser do not believe that the
anti-takeover laws and regulations of any state will by their terms apply to the
Offer and the Merger, and neither Parent nor Purchaser has determined whether
any other state takeover laws or regulations will by their terms apply to the
Offer or the Merger, and except as set forth above, neither Purchaser nor Parent
have attempted to comply with any state takeover statutes in connection with the
Offer or the Merger. Purchaser and Parent reserve the right to challenge the
validity or applicability of any state law allegedly applicable to the Offer or
the Merger, and nothing in this Offer to Purchase nor any action taken by Parent
or Purchaser in connection with the Offer is intended as a waiver of that right.
In the event it is asserted that one or more state takeover statutes is
applicable to the Offer or the Merger and an appropriate court does not
determine that it is inapplicable or invalid as applied to the Offer or the
Merger, Purchaser might be required to file certain information with, or to
receive approvals from, the relevant state authorities or holders of Shares, and
Purchaser might be unable to accept for payment or pay for Shares tendered
pursuant to the Offer, or be delayed in continuing or

                                       28
<PAGE>   37

consummating the Offer or the Merger. In such case, Purchaser may not be
obligated to accept for payment or pay for any tendered Shares. See Section 15
of this Offer to Purchase -- "Certain Conditions of the Offer."

     Antitrust in the United States. Under the HSR Act and the rules that have
been promulgated thereunder by the Federal Trade Commission (the "FTC"), certain
acquisition transactions may not be consummated unless certain information has
been furnished to the Antitrust Division of the Department of Justice (the
"Antitrust Division") and the FTC and certain waiting period requirements have
been satisfied. The purchase of Shares pursuant to the Offer is subject to such
requirements.

     Pursuant to the requirements of the HSR Act, Purchaser expects to file a
Notification and Report Form with respect to the Offer and the Merger with the
Antitrust Division and the FTC on or about September 19, 2000. The waiting
period applicable to the purchase of Shares pursuant to the Offer is scheduled
to expire at 11:59 p.m., New York City time, 15 days after such filing. However,
prior to such time, the Antitrust Division or the FTC may extend the waiting
period by requesting additional information or documentary material relevant to
the Offer from Purchaser. If such a request is made, the waiting period will be
extended until 11:59 p.m., New York City time, on the tenth day after
substantial compliance by Purchaser with such request. Thereafter, such waiting
period can be extended only by court order or by consent. Purchaser will not
accept for payment Shares tendered pursuant to the Offer unless and until the
waiting period requirements imposed by the HSR Act with respect to the Offer
have been satisfied. See Section 15 of this Offer to Purchase -- "Certain
Conditions of the Offer."

     Any extension of the waiting period will not give rise to any withdrawal
rights not otherwise provided for by applicable law. See Section 4 of this Offer
to Purchase -- "Withdrawal Rights." If Purchaser is delayed in its purchase of
Shares due to a request by the Antitrust Division or the FTC for additional
information or documentary material pursuant to the HSR Act, the Offer will be
extended in certain circumstances. See Section 15 of this Offer to
Purchase -- "Certain Conditions of the Offer."

     The Antitrust Division and the FTC scrutinize the legality under the
antitrust laws of transactions such as the purchase of Shares by Purchaser
pursuant to the Offer and the Merger. At any time before or after the
consummation of any such transactions, the Antitrust Division or the FTC could
take such action under the antitrust laws of the United States as it deems
necessary or desirable in the public interest, including seeking to enjoin the
purchase of Shares pursuant to the Offer or seeking divestiture of the Shares so
acquired or divestiture of substantial assets of Parent, the Company or their
respective affiliates. Private parties (including individual states) may also
bring legal actions under the antitrust laws of the United States. Purchaser
does not believe that the consummation of the Offer will result in a violation
of any applicable antitrust laws. However, there can be no assurance that a
challenge to the Offer on antitrust grounds will not be made, or if such a
challenge is made, what the result will be. See Section 15 of this Offer to
Purchase -- "Certain Conditions of the Offer," including conditions with respect
to litigation and certain governmental actions and Section 11 -- "The Merger
Agreement; Other Arrangements" for certain termination rights.

17. APPRAISAL RIGHTS

     Holders of Shares do not have appraisal rights in connection with the
Offer. However, if the Merger is consummated, holders of shares at the Effective
Time will have certain rights pursuant to Section 262 of the DGCL, including the
right to dissent and demand appraisal of, and to receive payment in cash of the
fair value of, their Shares (the "Dissenting Shares"). Under Section 262 of the
DGCL, dissenting stockholders of the Company who comply with the applicable
statutory procedures will be entitled to receive a judicial determination of the
fair value (excluding any element of value arising from the accomplishment or
expectation of the Merger) of their Dissenting Shares, and to receive payment of
such fair value in cash, together with a fair rate of interest thereon, if any.
Any such judicial determination of the fair value of Dissenting Shares could be
based upon considerations other than, or in addition to, the price per Share to
be paid in the Merger. The value so determined could be more or less than the
Offer Price or the Merger Consideration.

                                       29
<PAGE>   38

     THE FOREGOING SUMMARY OF THE RIGHTS OF DISSENTING STOCKHOLDERS UNDER THE
DGCL DOES NOT PURPORT TO BE A COMPLETE STATEMENT OF THE PROCEDURES TO BE
FOLLOWED BY STOCKHOLDERS OF THE COMPANY DESIRING TO EXERCISE ANY AVAILABLE
DISSENTERS' RIGHTS. THE FOREGOING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO SECTION 262 OF THE DGCL. THE PRESERVATION AND EXERCISE OF
DISSENTERS' RIGHTS REQUIRE STRICT ADHERENCE TO THE APPLICABLE PROVISIONS OF THE
DGCL.

18. FEES AND EXPENSES

     Parent and Purchaser have retained Innisfree M&A Incorporated to be the
Information Agent and First Chicago Trust Company of New York to be the
Depositary in connection with the Offer. The Information Agent may contact
holders of Shares by mail, telephone, telecopy, telegraph, facsimile, personal
interview and other methods of electronic communication and may request banks,
brokers, dealers and other nominees to forward materials relating to the Offer
to beneficial owners of Shares. The Information Agent and the Depositary each
will receive reasonable and customary compensation for their respective services
in connection with the Offer, will be reimbursed for reasonable out-of-pocket
expenses, and will be indemnified against certain liabilities and expenses in
connection therewith, including certain liabilities under federal securities
laws. Except as set forth above, neither Parent nor Purchaser will pay any fees
or commissions to any broker or dealer or to any other person, the Depositary
and the Information Agent in connection with the solicitation of tenders of
Shares pursuant to the Offer. Brokers, dealers, commercial banks and trust
companies will, upon request, be reimbursed by the Purchaser for customary
mailing and handling expenses incurred by them in forwarding offering materials
to their customers.

19. MISCELLANEOUS

     Neither Purchaser nor Parent is aware of any jurisdiction where the making
of the Offer is prohibited by any administrative or judicial action pursuant to
any valid state statute. If either Purchaser or Parent becomes aware of any
valid state statute prohibiting the making of the Offer or the acceptance of the
Shares, Parent and Purchaser will make a good faith effort to comply with that
state statute, or seek to have the statute declared inapplicable to the Offer.
If, after a good faith effort, Purchaser and Parent cannot comply with the state
statute, the Offer will not be made to, nor will tenders be accepted from or on
behalf of, the holders of Shares in that state. In any jurisdiction where the
securities, blue sky or other laws require the Offer to be made by a licensed
broker or dealer, the Offer shall be deemed to be made on behalf of Purchaser by
one or more properly licensed registered brokers or dealers.

     NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR TO MAKE ANY
REPRESENTATION ON BEHALF OF PARENT OR PURCHASER NOT CONTAINED IN THE OFFER
DOCUMENTS AND, IF GIVEN OR MADE, SUCH INFORMATION OR REPRESENTATION MUST NOT BE
RELIED UPON AS HAVING BEEN AUTHORIZED.

     Purchaser has filed with the SEC a Tender Offer Statement on Schedule TO
pursuant to Rule 14d-3 of the General Rules and Regulations under the Exchange
Act, together with exhibits furnishing certain additional information with
respect to the Offer, and may file amendments thereto. In addition, the Company
has filed with the SEC a Solicitation/Recommendation Statement on Schedule
14D-9, together with exhibits, pursuant to Rule 14d-9 under the Exchange Act,
setting forth the recommendations of the Company Board with respect to the Offer
and the reasons for such recommendations and furnishing certain additional
related information. A copy of such documents, and any amendments thereto, may
be examined at, and copies may be obtained from, the SEC (but not the regional
offices of the SEC) in the manner set forth under Section 7 of this Offer to
Purchase -- "Certain Information Concerning the Company" above.
