                                            -------

          WHEREAS, the Board of Directors of each of Parent, the Purchaser and

outstanding common stock, par value $0.001, of the Company (the "Shares"), for
                                                                 ------
$16.50 per share, net to the seller in cash (such price, or any such higher
price per Share as may be paid in the Offer, referred to herein as the "Offer
                                                                        -----
Price");
-----

          WHEREAS, also in furtherance of such acquisition, the Board of

          WHEREAS, the Board of Directors of the Company (the "Company Board of

to recommend that the holders of such Shares accept the Offer and approve this
Agreement and each of the Transactions (as defined in Section 3.4) upon the

          WHEREAS, as a condition and further inducement to Parent and the

          WHEREAS, the Company, Parent and Purchaser desire to make certain
representations, warranties, covenants and agreements in connection with the
Offer and the Merger.

          NOW, THEREFORE, in consideration of the foregoing and the mutual

                                   ARTICLE I

                              THE OFFER AND MERGER

          Section 1.1  The Offer.  (a)  Provided that this Agreement shall not
                       ---------
have been terminated in accordance with Section 8.1 and none of the events set
forth in Annex I hereto shall have occurred and be continuing, as promptly as
practicable, and, in any event, within eight (8) business days of the date
hereof, the Purchaser shall commence (within the meaning of Rule 14d-2 under the
Securities Exchange Act of 1934, as amended (the "Exchange Act")) the Offer to
                                                  ------------
purchase for cash all Shares at the Offer Price, subject only to (i) there being
validly tendered and not withdrawn prior to the expiration of the Offer that
number of Shares which, together with the Shares then beneficially owned by
Parent or the Purchaser, represents at least a majority of the Shares
outstanding on a fully-diluted basis, assuming the exercise of all options,
warrants, rights and convertible securities outstanding on the Expiration Date
(the "Minimum Condition") and (ii) the other conditions set forth in Annex I
      -----------------
hereto (the Minimum Condition, together with such other conditions set forth in
Annex I, collectively, the "Offer Conditions").  Subject to the prior
                            ----------------
satisfaction or waiver by Parent or the Purchaser of the Offer Conditions, the
Purchaser shall consummate the Offer in accordance with its terms and accept for
payment and pay for all Shares tendered pursuant to the Offer as soon as
Purchaser is legally permitted to do so under applicable law.  The obligations
of the Purchaser to commence the Offer and accept for payment and pay for any
Shares validly tendered on or prior to the expiration of the Offer and not
withdrawn shall be subject only to the Offer Conditions.  The Offer shall be
made by means of an offer to purchase (the "Offer to Purchase") that contains
                                            -----------------
the terms set forth in this Agreement and the Offer Conditions.  The Purchaser
shall not amend or waive the Minimum Condition, decrease the Offer Price, change
the form of consideration payable in the Offer, decrease the number of Shares
sought in the Offer, impose additional conditions to the Offer, extend the Offer
beyond the date that is twenty (20) business days after commencement of the
Offer or the last day of the last extension (in accordance with this Section
1.1), if any, of the Offer, whichever is later (the "Expiration Date") except as
                                                     ---------------
set forth below or amend any other condition of the Offer in any manner adverse
to the holders of the Shares without the prior written consent of the Company
(such consent to be authorized by the Company Board of Directors or a duly
authorized committee thereof), provided, however, that (x) if on the Expiration
                               --------  -------
Date, all Offer Conditions shall not have been satisfied or waived, the
Purchaser may, from time to time, in its sole discretion, extend the Offer for
such period as the Purchaser may determine, (y) the Purchaser may, in its sole
discretion, provide a

                                       3
<PAGE>

"subsequent offering period" in accordance with Rule 14d-11 under the Exchange
Act or (z) the Purchaser may, in its sole discretion, extend the Offer for any
reason on one or more occasions for an aggregate period of not more than 10
business days beyond the latest expiration date of the Offer that would
otherwise be permitted under clause (x) or (y) of this sentence if, on such
expiration date, there have not been tendered at least 90% of the outstanding
Shares; provided, further, however, that Purchaser's decision to extend the
        --------  -------  -------
Offer in the case of this clause (z) shall constitute a waiver of each Offer
Condition (other than the conditions set forth in paragraphs (a) and (b)). In
addition, the Purchaser may increase the Offer Price and extend the Offer to the
extent required by law in connection with such increase, in each case in its
sole discretion and without the Company's consent. Parent and Purchaser agree
that if at any scheduled Expiration Date of the Offer, the Minimum Condition,
the HSR Condition or any of the conditions set forth in paragraphs (c), (d) or
(g) of Annex 1 (but, in the case of failure of the condition set forth in
paragraph (d) of Annex 1, only where such failure is due to an unintentional
breach by the Company of the representations and warranties referred to therein)
shall not have been satisfied, but at such scheduled Expiration Date all of the
other Offer Conditions shall then be satisfied, or if not then satisfied (but
not including for such purposes the conditions set forth in paragraphs (e) of
Annex I which must be satisfied at the time of each request of the Company
pursuant to this sentence), are in Parent's good faith belief reasonably capable
of being satisfied, as to each of clauses (i), (ii) and (iii) below, prior to
the date which is indicated in each such clause as the latest date to which the
Offer may be extended pursuant to such clause, then, at the request of the
Company (confirmed in writing and received at least 24 hours prior to the then
scheduled Expiration Date), Purchaser shall extend the Offer from time to time
(each such individual extension not to exceed ten business days after the
previously scheduled expiration date, unless the parties otherwise agree), but
(i) in the case of the non-satisfaction of the HSR Condition only, to a date
that is no later than the Initial Drop Dead Date, or, in the case of the
election of Parent or the Company pursuant to Section 8.1(c)(iv), to the Second
Drop Dead Date, subject in each case to any right of Parent, Purchaser or the
Company to terminate this Agreement pursuant to the terms hereof and (ii) in the
case of condition set forth in paragraph (g) of Annex 1, to a date which is no
later than the date which is ten (10) days after the previously scheduled
Expiration Date, subject to any right of Parent, Purchaser or the Company to
terminate this Agreement pursuant to the terms hereof, and (iii) in all other
cases, to a date that is no later than the date which is fifty (50) days after
the date on which the Offer is commenced, subject to any right of Parent,
Purchaser or the Company to terminate this Agreement pursuant to the terms
hereof.

          (b) As soon as practicable on the date the Offer is commenced, Parent
and the Purchaser shall file with the Securities and Exchange Commission (the

"SEC"), pursuant to Regulation M-A under the Exchange Act ("Regulation M-A"), a
 ---                                                        --------------
Tender Offer Statement on Schedule TO with respect to the Offer (together with
all amendments, supplements and exhibits thereto, the "Schedule TO").  The
                                                       -----------
Schedule TO shall include the summary term sheet required under Regulation M-A
and, as exhibits, the Offer to Purchase and a form of letter of transmittal and
summary advertisement (collectively, together with any amendments and
supplements thereto, the "Offer Documents").  Parent and the Purchaser agree to
                          ---------------
take all steps necessary to cause the Offer Documents to be filed with the SEC
and disseminated to holders of Shares, in each case as and to the extent
required by applicable federal securities laws.  Parent and the Purchaser, on
the one hand, and the Company, on the other hand, agree to promptly correct any
information provided by it for use in the Offer Documents if and to the extent
that it shall have become false or misleading in any material respect or as
otherwise required by law.  The Purchaser further agrees to take all steps
necessary to cause the Offer Documents as so corrected to be filed with the SEC
and disseminated to holders of Shares, in each case as and to the extent
required by applicable federal securities laws.  The Company and its counsel
shall be given a reasonable opportunity to review the Schedule TO before it is
filed with the SEC.  In addition, Parent and the Purchaser agree to provide the
Company and its counsel in writing with any comments, whether written or oral,
that Parent, the Purchaser or their counsel may receive from time to time from
the SEC or its staff with respect to the Offer Documents promptly after Parent's
or the Purchaser's, as the case may be, receipt of such comments, and any
written or oral responses thereto.

          (c) Parent shall provide or cause to be provided to Purchaser on a
timely basis funds necessary to accept for payment, and to pay for, any Shares
that Parent becomes obligated to accept for payment, and pay for, pursuant to
the Offer.

          (d) Parent or Purchaser shall engage an information agent in
connection with the Offer.

          Section 1.2  Company Actions.  (a) In a manner in compliance with the
                       ---------------
Exchange Act and the Securities Act, with regards to timeliness, among other
things, the Company shall, in a manner that complies with Rule 14d-9 under the
Exchange Act, file with the SEC a Tender Offer Solicitation/Recommendation
Statement on Schedule 14D-9 (together with all amendments, supplements and
exhibits thereto, the "Schedule 14D-9") that shall, subject to the provisions of
                       --------------

                                       5
<PAGE>

Section 5.3(c), contain the recommendation referred to in clause (iii) of
Section 3.5.  The Company further agrees to take all steps necessary to cause
the Schedule 14D-9 to be filed with the SEC and disseminated to holders of
Shares, in each case as and to the extent required by applicable federal
securities laws.  The Company, on the one hand, and Parent and the Purchaser, on
the other hand, agree to promptly correct any information provided by it for use
in the Schedule 14D-9 if and to the extent that it shall have become false or
misleading in any material respect or as otherwise required by law.  The Company
agrees to take all steps necessary to cause the Schedule 14D-9 as so corrected
to be filed with the SEC and disseminated to holders of the Shares, in each case
as and to the extent required by applicable federal securities laws.  Parent,
the Purchaser and their counsel shall be given a reasonable opportunity to
review the Schedule 14D-9 before it is filed with the SEC.  In addition, the
Company agrees to provide Parent, the Purchaser and their counsel in writing
with any comments, whether written or oral, that the Company or its counsel may
receive from time to time from the SEC or its staff with respect to the Schedule
14D-9 promptly after the Company's receipt of such comments, and any written or
oral responses thereto.

          (b) In connection with the Offer, the Company shall promptly furnish
or cause to be furnished to the Purchaser mailing labels, security position
listings and any available listing or computer file containing the names and
addresses of the record holders of the Shares as of a recent date, and shall
promptly furnish the Purchaser with such information and assistance (including,
but not limited to, lists of holders of the Shares, updated daily, and their
addresses, mailing labels and lists of security positions) as the Purchaser or
its agent may reasonably request for the purpose of communicating the Offer to
the record and beneficial holders of the Shares.  Subject to the requirements of
applicable law, and except for such steps as are necessary to disseminate the
Offer Documents and any other documents necessary to consummate the Merger,
Parent and Purchaser shall, and shall cause their agents to, hold in confidence
the information contained in any such labels, listings and files, use such
information only in connection with the Offer and the Merger and, if this
Agreement is terminated, upon request, deliver, and use their reasonable efforts
to cause their agents to deliver, to the Company all copies of such information
then in their possession or control.

          Section 1.3  Directors.  (a) Promptly upon the purchase of and payment
                       ---------
for any Shares by Parent or the Purchaser which represents at least a majority
of the outstanding Shares (on a fully-diluted basis), Parent shall be entitled
to elect or designate such number of directors, rounded up to the next whole
number,

                                       6
<PAGE>

on the Company Board of Directors as is equal to the product of the total number
of directors on the Company Board of Directors (giving effect to the directors
elected or designated by Parent pursuant to this sentence) multiplied by the
percentage that the aggregate number of Shares owned by the Purchaser, Parent
and any of their affiliates bears to the total number of Shares then
outstanding. The Company shall, upon Parent's request, use its reasonable
efforts either to promptly increase the size of the Company Board of Directors,
including by amending the Bylaws of the Company if necessary so as to increase
the size of the Company Board of Directors, or promptly secure the resignations
of such number of its incumbent directors, or both, as is necessary to enable
Parent's designees to be so elected or designated to the Company's Board of
Directors, and shall use its reasonable efforts to cause Parent's designees to
be so elected or designated at such time. At such time, the Company shall, upon
Parent's request, also cause persons elected or designated by Parent to
constitute the same percentage (rounded up to the next whole number) as is on
the Company Board of Directors of (i) each committee of the Company Board of
Directors, (ii) each board of directors (or similar body) of each Company
Subsidiary (as defined in Section 3.2), and (iii) each committee (or similar
body) of each such board, in each case only to the extent permitted by
applicable law or the rules of any stock exchange on which the Company Common
Stock is listed. The Company's obligations under this Section 1.3(a) shall be
subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated
thereunder. The Company shall promptly upon execution of this Agreement take all
actions required pursuant to such Section 14(f) and Rule 14f-1 in order to
fulfill its obligations under this Section 1.3(a), including, but not limited
to, mailing to stockholders (together with the Schedule 14D-9) the information
required by Section 14(f) and Rule 14f-1 as is necessary to enable Parent's
designees to be elected or designated to the Company Board of Directors. Parent
or the Purchaser shall supply the Company with information with respect to
either of them and their nominees, officers, directors and affiliates to the
extent required by Section 14(f) and Rule 14f-1. The provisions of this Section
1.3(a) are in addition to and shall not limit any rights that any of the
Purchaser, Parent or any of their respective affiliates may have as a holder or
beneficial owner of Shares as a matter of law with respect to the election of
directors or otherwise.

          (b) In the event that Parent's designees are elected or designated to
the Company Board of Directors, then, until the Effective Time, the Company
shall cause the Company Board of Directors to have at least two directors who
are non-executive directors (the "Independent Directors"); provided, however,
                                  ---------------------    --------  -------
that if any Independent Director is unable to serve due to death or disability,
the remaining Independent Director(s) shall be entitled to elect or designate
another person (or

                                       7

Independent Directors (or if only one exists, then the vote of such Independent
Director) shall be required to (i) amend or terminate this Agreement by the
Company, (ii) exercise or waive any of the Company's rights, benefits or
remedies hereunder, if such action would materially and adversely affect holders
of Shares other than Parent or Purchaser, (iii) amend the Certificate of

     Company vote in favor of the approval of the Merger and the adoption of
     this Agreement; and

     faith, following the advice from outside counsel, that to do so is

     other action reasonably necessary or advisable to secure the approval of

action to cause the Merger to become effective as soon as practicable after such

          (b) Cancellation of Treasury Stock and Parent-Owned Stock.  All Shares
              -----------------------------------------------------
that are owned by the Company as treasury stock and any Shares owned by Parent,
the Purchaser or any other wholly-owned Subsidiary of Parent shall be cancelled
and retired and shall cease to exist, and no consideration shall be delivered in
exchange therefor.

          (c) Conversion of Shares.  Each issued and outstanding Share (other
              --------------------
than Shares to be cancelled in accordance with Section 2.1(b) and other than
Dissenting Shares (as defined in Section 2.3)) shall be converted into the right
to receive the Offer Price, payable to the holder thereof in cash, without
interest (the "Merger Consideration").  From and after the Effective Time, all
               --------------------
such Shares shall no longer be outstanding and shall automatically be cancelled
and retired and shall cease to exist, and each holder of a certificate
representing any such Shares shall cease to have any rights with respect
thereto, except the right to receive the Merger Consideration therefor upon the
surrender of such certificate in accordance with Section 2.2, without interest
thereon.

          (d) Conversion of Stock Options.  Each Company Stock Option (as
              ---------------------------
hereinafter defined) shall be treated in accordance with Section 2.4 below.

          Section 2.2  Exchange of Certificates.  (a)  Paying Agent.  Parent
                       ------------------------        ------------
shall designate a bank or trust company to act as agent for the holders of
Shares in connection with the Merger (the "Paying Agent") and to receive the
                                           ------------
funds to which holders of Shares shall become entitled pursuant to Section
2.1(c).  Prior to the Effective Time, Parent or the Purchaser shall deposit, or
cause to be deposited, with the Paying Agent the aggregate Merger Consideration.
For purposes of determining the amount of Merger Consideration to be so
deposited, Parent and the Purchaser shall assume that no stockholder of the
Company will perfect any right to appraisal of his, her or its Shares.  Such
funds shall be invested by the Paying Agent as directed by Parent or the
Surviving Corporation, in its sole discretion, pending payment thereof by the
Paying Agent to the holders of the Shares.  Earnings from such investments shall
be the sole and exclusive property of Parent and the Surviving Corporation, and
no part of such earnings shall accrue to the benefit of holders of Shares.

          (b) Exchange Procedures.  Promptly after the Effective Time, the
              -------------------
Paying Agent shall mail to each holder of record of a certificate or
certificates, which

                                       12
<PAGE>

immediately prior to the Effective Time represented outstanding Shares
(the "Certificates"), whose shares were converted pursuant to
      ------------
Section 2.1 into the right to receive the Merger Consideration (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Paying Agent and shall be in such form and have such other
provisions as Parent may reasonably specify) and (ii) instructions for effecting
the surrender of the Certificates in exchange for payment of the Merger
Consideration. Upon surrender of a Certificate for cancellation to the Paying
Agent or to such other agent or agents as may be appointed by Parent, together
with such letter of transmittal, duly executed, the holder of such Certificate
shall be entitled to receive in exchange therefor the Merger Consideration for
each Share formerly represented by such Certificate and the Certificate so
surrendered shall forthwith be cancelled. If payment of the Merger Consideration
is to be made to a Person other than the Person in whose name the surrendered
Certificate is registered, it shall be a condition precedent of payment that (x)
the Certificate so surrendered shall be properly endorsed or shall be otherwise
in proper form for transfer, and (y) the Person requesting such payment shall
have paid any transfer and other taxes required by reason of the payment of the
Merger Consideration to a Person other than the registered holder of the
Certificate surrendered or shall have established to the satisfaction of the
Surviving Corporation that such tax either has been paid or is not required to
be paid. Until surrendered as contemplated by this Section 2.2, each Certificate
shall be deemed at any time after the Effective Time to represent only the right
to receive the Merger Consideration in cash as contemplated by this Section 2.2,
without interest thereon.

          (c) Transfer Books; No Further Ownership Rights in Shares.  At the
              -----------------------------------------------------
Effective Time, the stock transfer books of the Company shall be closed and
thereafter there shall be no further registration of transfers of Shares on the
records of the Company.  From and after the Effective Time, the holders of
Certificates evidencing ownership of Shares outstanding immediately prior to the
Effective Time shall cease to have any rights with respect to such Shares,
except as otherwise provided for herein or by applicable law.  If, after the
Effective Time, Certificates are presented to the Surviving Corporation for any
reason, they shall be cancelled and exchanged as provided in this Article II.

          (d) Termination of Fund; No Liability.  At any time following six
              ---------------------------------
months after the Effective Time, the Surviving Corporation shall be entitled to
require the Paying Agent to deliver to it any funds (including any interest
received with respect thereto) made available to the Paying Agent and not
disbursed (or for which disbursement is pending subject only to the Paying
Agent's routine

                                       13
<PAGE>

administrative procedures) to holders of Certificates, and thereafter such
holders shall be entitled to look only to the Surviving Corporation (subject to
abandoned property, escheat or other similar laws) only as general creditors
thereof with respect to the Merger Consideration payable upon due surrender of
their Certificates, without any interest thereon. Notwithstanding the foregoing,
neither the Surviving Corporation nor the Paying Agent shall be liable to any
holder of a Certificate for Merger Consideration delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law.

          Section 2.3  Dissenting Shares.  (a)  Notwithstanding anything in
                       -----------------
this Agreement to the contrary, Shares outstanding immediately prior to the
Effective Time and held by a holder who has not voted in favor of the Merger or
consented thereto in writing and who has complied with Section 262 of the DGCL
("Dissenting Shares") shall not be converted into a right to receive the Merger
  -----------------
Consideration, unless such holder fails to perfect or withdraws or otherwise
loses his or her right to appraisal.  A holder of Dissenting Shares shall be
entitled to receive payment of the appraised value of such Shares held by him or
her in accordance with Section 262 of the DGCL, unless, after the Effective
Time, such holder fails to perfect or withdraws or loses his or her right to
appraisal, in which case such Shares shall be converted into and represent only
the right to receive the Merger Consideration, without interest thereon, upon
surrender of the Certificate or Certificates representing such Shares pursuant
to Section 2.2.

          (b) The Company shall give Parent (i) prompt notice of any written
demands for appraisal of any Shares, attempted withdrawals of such demands and
any other instruments served pursuant to the DGCL and received by the Company
relating to rights of appraisal and (ii) the opportunity to participate in the
conduct of all negotiations and proceedings with respect to demands for
appraisal under the DGCL.  Except with the prior written consent of Parent, the
Company shall not voluntarily make any payment with respect to any demands for
appraisal or settle or offer to settle any such demands for appraisal.

          Section 2.4   Company Option Plans.   (a)  Parent acknowledges that,
                        --------------------
in accordance with determinations by the Company Board of Director pursuant to
the Company Stock Option Plans (as defined below), at the Effective Time, each
stock option, stock equivalent right or similar right to acquire Shares (each, a
"Company Stock Option") issued pursuant to the Company's 1997 Stock Option Plan
 --------------------
or the Company's Amended and Restated 1999 Stock Incentive Plan (including the
Company's 1999 Non-Employee Director Option Program, as amended, thereunder)
(collectively, the "Company Stock Option Plans"), whether or not then
                    --------------------------

                                       14
<PAGE>

exercisable or vested, which is outstanding and unexercised immediately prior
thereto shall become immediately fully vested and exercisable. At the Effective
Time, each Company Stock Option shall cease to represent a right to acquire
Shares and shall be converted automatically into options to purchase shares of
Parent common stock ("Parent Shares"), and Parent shall assume each such Company
Stock Option (hereinafter, an "Assumed Option") subject to the terms of the
applicable Company Stock Option Plan and the agreement evidencing the grant
thereunder of such Company Stock Option; provided, however, that from and after
the Effective Time, (A) the number of Parent Shares purchasable upon exercise of
an Assumed Option shall be equal to the number of Shares that were purchasable
under such Assumed Option immediately prior to the Effective Time multiplied by
the Exchange Ratio (as defined below), and rounded down to the nearest whole
share, and (B) the per share exercise price under such Assumed Option shall be
adjusted by dividing the per share exercise price under such Assumed Option by
the Exchange Ratio, and rounding up to the nearest cent.  In the case of any
Assumed Options that are "incentive stock options" (as defined in Section 422 of
the Code), the exercise price, the number of Parent Shares purchasable pursuant
to such options and the terms and conditions of exercise of such options shall
be determined in order to comply with Section 424(a) of the Code.  For purposes
of this Section 2.4, the "Exchange Ratio" shall be the number obtained by
dividing the Merger Consideration by the closing price of a Parent Share on the
trading day immediately preceding the Closing Date.

     (b) The Company shall take all such steps as may be required to cause any
dispositions of Shares (including derivative securities with respect to Shares)
resulting from the transactions contemplated by Article II of this Agreement by
each individual who is subject to the reporting requirements of Section 16(a) of
the Exchange Act with respect to the Company, to be exempt under Rule 16b-3
promulgated under the Exchange Act.

     (c) Prior to the Effective Time, the Company Stock Option Plans shall
terminate and all rights under any provision of any other plan, program or
arrangement providing for the issuance or grant of any other interest in respect
of the capital stock of the Company or any Company Subsidiary (as defined in
Section 3.2(a)) shall be cancelled.

     (d) As soon as practicable after the Effective Time, Parent shall deliver
to each holder of an outstanding Company Stock Option an appropriate notice
setting forth such holder's rights pursuant thereto and such Company Stock
Option shall continue in effect on the same terms and conditions (subject to the
adjustments

                                       15
<PAGE>

required by this Section 2.4 after giving effect to the Merger). Parent shall
take all corporate action necessary to reserve for issuance a sufficient number
of shares of Parent Shares for delivery upon exercise of such Assumed Options
pursuant to the terms set forth in this Section 2.4.

     (e) Parent shall file with the SEC, prior to the Effective Time, a
registration statement on Form S-8 (or any successor form) relating to Parent
Shares issuable pursuant to the Assumed Options, which registration statement
shall include a reoffer prospectus. Parent shall use its commercially reasonable
efforts to cause shares of Parent Shares, when issued upon exercise of Assumed
Options, to be listed on such exchanges as Parent Shares are listed immediately
prior to the Effective Time.

     (f) Prior to the Appointment Date, the Company shall cause the
administrator of the Company Option Plans to clarify certain language in such
plans in order to further determine that the actions taken with respect to the
Company Stock Options pursuant to this Section 2.4 are consistent with the terms
of the Company Option Plans.

                                  ARTICLE III

                              REPRESENTATIONS AND
                           WARRANTIES OF THE COMPANY

          Except as set forth in the schedule of exceptions to the Company's
representations and warranties set forth herein, delivered to Parent prior to
the execution of this Agreement (the "Company Disclosure Schedule"), the Company
                                      ---------------------------
represents and warrants to Parent and the Purchaser as set forth below.

          Section 3.1  Organization.  (a)  The Company is a corporation duly
                       ------------
organized, validly existing and in good standing under the laws of the State of
Delaware and has the requisite corporate power and authority and all necessary
governmental licenses, authorizations, permits, consents and approvals to own,
lease and operate its properties and to carry on its business as it is now being
conducted, except where the failure to be so organized, existing and in good
standing or to have such power, authority, or governmental licenses,
authorizations, permits, consents or approvals would not, individually or in the
aggregate, (A) be reasonably expected to

                                       16
<PAGE>

have a Company Material Adverse Effect or (B) be reasonably likely to have a
material adverse effect on the Company's ability to consummate the Transactions.
As used in this Agreement, "Company Material Adverse Change" or "Company
                            -------------------------------      -------
Material Adverse Effect" means any change, event or effect, as the case may be,
-----------------------
that is materially adverse to the business, operations, properties (including
intangible properties), condition (financial or otherwise), results of
operations, or assets or liabilities, with all such matters being considered in
the aggregate, of the Company and the Company Subsidiaries, taken as a whole,
except any such change, event or effect resulting primarily from: (i) any change
in the market price or trading volume of the Company's securities; (ii)
conditions (including changes in economic, financial market, regulatory or
political conditions) affecting generally the online travel or leisure travel
industries in which the Company participates, (iii) actions taken, delayed or
omitted to be taken by the Company at the written request of any of the
individuals specified in Schedule 3.1(a)(iii) of the Company Disclosure Schedule
("Designated Parent Individuals") after the date hereof and prior to the earlier
of (A) the termination of this Agreement in accordance with Article VIII and (B)
the Appointment Date, (iv) items set forth in Section 3.1(a)(iv) in the Company
Disclosure Schedule; or (v) any disruption of employee (other than as set forth
in Section 3.1(a)(v) in the Company Disclosure Schedule), customer, supplier or
other similar relationships or other events or circumstances resulting primarily
from or which are primarily attributable to the execution or announcement of
this Agreement and the identity of the Parent.

          (b) The Company is duly qualified or licensed to do business and in
good standing (to the extent the concept of good standing exists) in each
jurisdiction in which the property owned, leased or operated by it or the nature
of the business conducted by it makes such qualification or licensing necessary,
except where the failure to be so qualified or licensed or in good standing
would not, individually or in the aggregate, be reasonably likely to have a
Company Material Adverse Effect.

     Section 3.2  Subsidiaries and Affiliates.  (a)  Section 3.2(a) of the
                  ---------------------------
Company Disclosure Schedule sets forth the name, jurisdiction of incorporation
or organization and authorized and outstanding capital of each Company
Subsidiary and the jurisdictions in which each Company Subsidiary is qualified

Company does not own, directly or indirectly, any capital stock or other equity
securities of any corporation or have any direct or indirect equity or ownership
interest in any business other than publicly-traded securities constituting less
than five percent of the outstanding equity of the issuing entity.  All of the
outstanding capital stock of each Company

                                       17

Subsidiary is owned directly or indirectly by the Company free and clear of all
liens, charges, security interests, options, claims, mortgages, title defects or

contracts, collateral security arrangements and other title or interest
retention arrangements, pledges, or other encumbrances and restrictions of any
nature whatsoever ("Encumbrances"), and is validly issued, fully paid and

kind relating to the issuance, sale or transfer of any capital stock or other
equity securities of any such Company Subsidiary to any person except the

other organization, whether incorporated or unincorporated, of which (i) at
least a majority of the securities or other interests having by their terms
ordinary voting power to elect a majority of the board of directors or others
performing similar functions with respect to such corporation or other
organization is directly or indirectly owned or controlled by such party or by
any one or more of its Subsidiaries, or by such party and one or more of its
Subsidiaries or (ii) such party or any other Subsidiary of such party is a
general partner (excluding any such partnership where such party or any
Subsidiary of such party does not have a majority of the voting interest in such
partnership). As used in this Agreement, the term "Person" means a natural

exists) in each jurisdiction in which the property owned, leased or operated by
it or the nature of the business conducted by it makes such qualification or

and in good standing would not individually or in the aggregate be reasonably
expected to have a Company Material Adverse Effect.  Each jurisdiction in which
a Company Subsidiary is organized or qualified or licensed to do business is
listed in Section 3.2(b) of the Company Disclosure Schedule.  The Company has
heretofore delivered to Parent complete and correct copies of the Certificate of

other corporate action on the part of the Company is necessary (other than, with
respect to the Merger, the approval and adoption of the Merger and this
Agreement by holders of a majority of the Shares and the filing of the
Certificate of Merger as required by the DGCL) to authorize the execution and
delivery by the Company of this Agreement and the consummation by it of the
Transactions.  This Agreement has been duly executed and delivered by the
Company and, assuming due and valid authorization, execution and delivery hereof
by Parent and the Purchaser, is a valid and binding obligation of the Company
enforceable against the Company in accordance with its terms, except that (i)
such enforcement may be subject to applicable bankruptcy, insolvency or other
similar laws, now or hereafter in effect, affecting creditors' rights generally,

Agreement and the Merger, and, subject to Section 5.3 of this Agreement, none of
the aforesaid actions by the Company Board of Directors has been amended,
rescinded or modified after the date hereof.  The action taken by the Company
Board of Directors constitutes approval of the Transactions (including each of
the Offer and the Merger) by the Company Board of Directors under Section 203 of

                       ---------------
to be terminated all existing discussions, negotiations and communications with
any Persons with respect to any Acquisition Proposal.   Except as provided in
Section 5.3(b), from the date of  this Agreement until the earlier of
termination of this Agreement or the Effective Time, the Company shall not and
shall not authorize or permit its Representatives to, and shall use its best
efforts to cause its Other Employees not to, directly or indirectly (i)
initiate, solicit or knowingly encourage, or knowingly take any action to
facilitate the making of, any offer or proposal which constitutes or is

agreement with respect to any Acquisition Proposal, or (iii) in the event of an
unsolicited Acquisition Proposal for the Company, engage in negotiations or
discussions with, or provide any information or data concerning the Company's
business, properties or assets to, any Person (other than Parent or any of its
affiliates or representatives) relating to any Acquisition Proposal.  Any
violation of the foregoing restrictions by any of the Company's Representatives,
whether or not such Representative is so authorized and whether or not such
Representative is purporting to act on behalf of the Company or otherwise, shall
be deemed to be a breach of this Agreement by the Company.  Notwithstanding the
foregoing, nothing contained in this Section 5.3 or any other provision hereof
shall prohibit the Company or the Company Board of Directors from (i) complying
with Rule 14d-9 or Rule 14e-2 promulgated under the Exchange Act, including
taking and disclosing to the Company's stockholders its position with respect to
tender or exchange offer by a third party pursuant to Rules 14d-9 and 14e-2
promulgated under the Exchange Act,

                                       50
<PAGE>

(ii) making such disclosure to the Company's stockholders as in the good-faith
judgment of the Company Board of Directors, only after receipt of advice from
outside legal counsel to the Company that such disclosure is required under
applicable law or (iii) referring a third party to this Section 5.3(a) or making
a copy of this Section 5.3(a) available to any third party.

          (b) Notwithstanding the foregoing, prior to the acceptance of Shares
pursuant to the Offer, the Company may furnish information and data concerning
its business, properties and assets to any Person pursuant to a confidentiality
agreement with terms no less favorable to the Company than those contained in
the Confidentiality Agreement, dated May 24, 2001 entered into between Parent
and the Company (the "Confidentiality Agreement") and may negotiate and
                      -------------------------
participate in discussions and negotiations with such Person concerning an
Acquisition Proposal if, but only if, (x) such Acquisition Proposal is for (i) a
merger or other business combination involving the Company, (ii) a proposal or
offer to acquire in any manner, directly or indirectly, an equity interest in or
any voting securities of the Company representing 25% or more of the Shares or
of the total voting securities of the Company outstanding or (iii) an offer to
acquire in any manner, directly or indirectly, a substantial portion of the
assets of the Company, other than the transactions contemplated by this
Agreement (a "Takeover Proposal"); (y) such entity or group has on an
              -----------------
unsolicited basis, and in the absence of any violation of this Section 5.3 by
the Company, submitted a bona fide written proposal to the Company relating to
any such Takeover Proposal which the Board of Directors determines in good
faith, after consultation with outside legal counsel and a nationally recognized
investment banking firm, involves consideration to the holders of the Shares
that is superior to the consideration offered pursuant to the Offer,
considering, among other things, the nature of the currency being offered, or
otherwise is reasonably likely to represent a superior transaction to the Offer
and the Merger and which is not conditioned upon obtaining additional financing
other than that which is committed (or which in the good faith judgment of the
Board of Directors, after consultation with a nationally recognized investment
banking firm, is reasonably capable of being obtained by such Person), and (z)
in the good faith opinion of the Company Board of Directors, only after
consultation with outside legal counsel to the Company, providing such
information or access or engaging in such discussions or negotiations is in the
best interests of the Company and its stockholders and the failure to provide
such information or access or to engage in such discussions or negotiations
would be reasonably likely to cause the Company Board of Directors to violate
its fiduciary duties to the Company's stockholders under applicable law (an
Acquisition Proposal which satisfies clauses (x), (y) and (z) being referred to
herein as a "Superior Proposal").  The Company shall within twenty-four (24)
             -----------------
hours

                                       51

following receipt (to the Company's knowledge) of a Takeover Proposal notify
Parent of receipt of the same, and provide Parent with a copy of such Takeover
Proposal or otherwise set forth in such notice the material terms and conditions
of such Takeover Proposal and identity of the Person making such Takeover
Proposal. The Company shall promptly, and in any event within twenty-four (24)
hours following a determination by the Company Board of Directors that a
Takeover Proposal is a Superior Proposal and prior to providing any such party
with any material non-public information, notify Parent of such determination.
The Company shall promptly provide to Parent any material non-public information
regarding the Company provided to any other party which was not previously
provided to Parent, such additional information to be provided no later than the
date of provision of such information to such other party.

          (c) Except as set forth herein, neither the Company Board of Directors
nor any committee thereof shall (i) withdraw or modify, or propose to withdraw
or modify, in a manner adverse to the Transactions, to Parent or to the
Purchaser, the approval or recommendation by the Company Board of Directors or
any such committee of the Offer, this Agreement or the Merger, (ii) approve or
recommend or propose to approve or recommend, any Acquisition Proposal or (iii)
enter into any agreement (other than a confidentiality agreement in accordance
with this Section 5.3) with respect to any Acquisition Proposal.
Notwithstanding the foregoing, prior to the time of acceptance for payment of
Shares in the Offer, the Company Board of Directors may (subject to the terms of
this and the following sentence) (A) withdraw or modify its approval or
recommendation of the Offer, this Agreement or the Merger, if after consultation
with its independent legal counsel, it determines in good faith that failure to
take such action would be reasonably likely to cause it to violate its fiduciary
duties to Company stockholders under applicable law, or (B) approve or recommend
a Superior Proposal, or enter into an agreement with respect to a Superior
Proposal, in the case of each of clauses (A) and (B), if at any time after
seventy-two (72) hours (or, if longer, two business days) have elapsed following
the Company's delivery to Parent of written notice advising Parent that the
Company Board of Directors has received a Superior Proposal specifying the
material terms and conditions of such Superior Proposal and identifying the
Person making such Superior Proposal; provided, however, that the Company shall
                                      --------  -------
not enter into an agreement with respect to a Superior Proposal unless the
Company shall also have terminated this Agreement in compliance with Section
5.3(d).  Any such withdrawal, modification or change of the recommendation or
the Company Board of Directors, the approval or recommendation or proposed
approval or recommendation of any Superior Proposal or the entry by the Company
into any agreement with respect to any Superior Proposal shall not change the
approval of the Company Board of

                                       52
<PAGE>

Directors for purposes of causing any state takeover statute or other state law
to be inapplicable to the Transactions, including each of the Offer, the Merger
and the Stockholder Agreement.

          (d) Notwithstanding anything in this Agreement to the contrary, the
Company may terminate this Agreement and enter into a letter of intent,
agreement-in-principle, acquisition agreement or other similar agreement (each,
an "Acquisition Agreement") with respect to a Superior Proposal, provided that,
    ---------------------                                        --------
prior to any such termination, (i) the Company has provided Parent written
notice that it intends to terminate this Agreement pursuant to this Section
5.3(d), identifying the Superior Proposal then determined to be more favorable
and the parties thereto and delivering a copy of the Acquisition Agreement for
such Superior Proposal in the form to be entered into, (ii) during the period
following the delivery of the second notice referred to in clause (i) above and
ending upon the delivery of the notice referred to in clause (iii) below, Parent
shall have the right to propose adjustments in the terms and conditions of this
Agreement and the Company shall have caused its financial and legal advisors to
negotiate with Parent in good faith such proposed adjustments in the terms and
conditions of this Agreement, and (iii) (A) at least seventy-two (72) hours (or,
if longer, two business days) after the Company has provided the notice referred
to in clause (i) above, the Company delivers to Parent a written notice of
termination of this Agreement pursuant to this Section 5.3(d) (such notice may
be given by the Company contingent upon termination of this Agreement becoming
effective immediately prior to the Company entering into a definitive agreement
with respect to the Superior Proposal), and (B) prior to the effective
termination of the Agreement, the Company delivers to Parent (x) a cashier's
check in the amount of the Termination Fee (as defined in Section 8.2(b)) plus
the reasonable out-of-pocket expenses of Parent and Purchaser as set forth in
Section 8.2(b), as the same may have been estimated by Parent in good faith
prior to the date of such delivery (subject to an adjustment payment between the
parties upon Parent's definitive determination of such expenses) and (y) a
written acknowledgment from each other party to such Superior Proposal that
waives any right it may have to contest the validity or enforceability of any of
the terms and conditions of this Agreement.

6.2 shall require any party to waive or exercise any right hereunder which is
waivable or exercisable in the sole discretion of such party.  In case at any

                       ------------------
terms and subject to the conditions of this Agreement, the Purchaser and the
Company agree to use their respective reasonable efforts to take, or cause to be
taken, all actions, and to do, or cause to be done, all things reasonably
necessary and appropriate, under applicable laws to consummate and make
effective the Transactions as promptly as practicable including, but not limited
to (i) the preparation and filing of all forms, registrations and notices
required to be filed to consummate the Transactions and the taking of such
actions as are necessary to obtain any requisite approvals, consents, orders,
exemptions or waivers by any third party or Governmental Entity, and (ii) the
satisfaction of the Offer Conditions and other parties' conditions to Closing.
In addition, no party hereto shall take any action after the date hereof that
would reasonably be expected to materially delay the obtaining of, or result in
not obtaining, any permission, approval or consent from any Governmental Entity
necessary to be obtained prior to Closing.

other parties hereto with respect to, provide any necessary information with

by such party with any Governmental Entity or any other information supplied by
such party to a Governmental Entity in connection with this Agreement and the
Transactions.  Each party hereto shall promptly inform the other of any
communication from any Governmental Entity regarding any of the Transactions
unless otherwise prohibited by law.  If any party hereto or affiliate thereof
receives a request for additional information or documentary material from any
such Government Entity with respect to the Transactions, then such party shall
endeavor in good faith to make, or cause to be made, as soon as reasonably
practicable and after consultation with the other party, an appropriate response
in compliance with such request.  To the extent that transfers, amendments or
modifications of permits (including environmental permits) are required as a
result of the execution of this Agreement or consummation of the Transactions,
the Company shall use its commercially reasonable efforts to effect such
transfers.

          (c) Notwithstanding the foregoing, nothing in this Agreement shall
require the Purchaser to defend against any litigation brought by any
Governmental Entity seeking to prevent the consummation of the Transactions.

sentence, but without relieving any party hereto of any obligation hereunder,
this Agreement will be binding upon, inure to the benefit of and be enforceable

any of their respective Subsidiaries or affiliates) of all or a material portion
of their or the Company's and the Company Subsidiaries' businesses or assets,
taken as a whole, or to compel Parent or the Purchaser or their respective
Subsidiaries and affiliates to dispose of or hold separate any material portion
of the business or assets of the Company or Parent and their respective
Subsidiaries, in each case taken as a whole, (ii) challenging the acquisition by
Parent or the Purchaser of any Shares under the Offer, seeking to restrain or
prohibit the making or consummation of the Transactions, or seeking to obtain
from the Company, Parent or the Purchaser, by reason of any of the Transactions,
any damages that would reasonably be likely to have a Company Material Adverse
Effect, (iii) seeking to impose material limitations on the ability of the
Purchaser, or render the Purchaser unable, to accept for payment, pay for or
purchase some or all of the Shares pursuant to the Offer and the Merger

                                      A-1

reasonably likely to have a Company Material Adverse Effect;

          (b) there shall be any statute, rule, regulation, judgment, order or
injunction enacted, entered, enforced, promulgated or deemed applicable,
pursuant to an authoritative interpretation by or on behalf of a Government
Entity, to the Offer or the Merger, or any other action shall be taken by any
Governmental Entity, other than the application to the Offer or the Merger of
applicable waiting periods under the  HSR Act or any comparable provisions of

any of the consequences referred to in clauses (i) through (v) of paragraph (a)
above;

          (c) there shall have occurred and be continuing (i) any general
suspension of trading in, or limitation on prices for, securities on the NASDAQ

triggered solely as a result of a specified decrease in a market index or
suspensions or limitations resulting solely from physical damage, technological
or software breakdowns or malfunctions or interference with such exchanges not
related to market conditions), (ii) a declaration by a Governmental Entity of a
banking moratorium or any suspension of payments in respect of banks in the
United States, (iii) a commencement of a war, armed hostilities or other
international or national calamity directly or indirectly involving the United
States, which in any case is reasonably expected to have a Company Material
Adverse Effect or to materially adversely affect Parent's or Purchaser's ability
to consummate the Transactions, or  (iv) any extraordinary limitation (whether
or not mandatory) by any Governmental Entity on the extension of credit
generally by banks or other financial institutions or (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

(which need only be true and correct as of such date or time), unless the
inaccuracies under such representations and warranties (without giving effect to
any materiality or material adverse effect qualifier or standard contained in
any such representation or warranty), taken together in their entirety, would

Company Material Adverse Effect; (ii) any of the representations and warranties
contained in (A) Section 3.3 of this Agreement shall not be true and correct as
of the date hereof and as of the Expiration Date; (B) in Section 3.23 or in the

respects as of the date hereof and as of the Expiration Date; or (iii)
inaccuracies in or breaches of any of the representations and warranties
contained in any of Sections 3.1, 3.2, 3.4, 3.5 or 3.6 shall be reasonably
likely to have a material adverse effect on the ability of either the Company or
Parent to consummate any of the Transactions.

          (e) since the date of this Agreement, there shall have occurred any
events or changes which have had, individually or in the aggregate, a Company
Material Adverse Change;

Company Board of Directors or any committee thereof to review and make a

circumstances giving rise to such condition, and may be waived by Parent or the
Purchaser in whole or in part at any time and from time to time and in the sole
discretion of Parent or the Purchaser, subject in each case to the terms of this
Agreement.  The failure by Parent or the 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.

          The capitalized terms used in this Annex I shall have the meanings set
forth in the Agreement to which it is annexed, except that the term "Merger
                                                                     ------
