                      AGREEMENT AND PLAN OF REORGANIZATION

   This AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made and
entered into as of January 3, 2001, by and among Ashford.com, Inc., a Delaware
corporation ("Acquiror"), Ashford-Guild Art Corporation, a Delaware corporation
("Merger Sub") and Guild.com, Inc., a Delaware corporation ("Target").

                                    RECITALS

   A. The Boards of Directors of Target, Acquiror and Merger Sub believe it is
in the best interests of their respective companies and stockholders of their
respective companies that Target and Merger Sub combine into a single Target
through the merger of Merger Sub with and into Target (the "Merger") and, in
furtherance thereof, have approved the Merger.

   B. Pursuant to the Merger, among other things, each outstanding share of
Target common stock, $0.001 par value ("Target Common Stock"), and Target
preferred stock, $0.001 par value ("Target Preferred Stock," collectively
"Target Capital Stock"), shall be converted into shares of common stock of
Acquiror, $0.001 par value ("Acquiror Common Stock"), at the rate(s) set forth
herein.

   C. Target, Acquiror and Merger Sub desire to make certain representations
and warranties and other agreements in connection with the Merger and to
prescribe various conditions to the Merger.

   D. The parties intend, by executing this Agreement, to adopt a plan of
reorganization within the meaning of Section 368 of the Internal Revenue Code
of 1986, as amended (the "Code"), and to cause the Merger to qualify as a
reorganization under the provisions of Sections 368(a)(1)(A) and 368(a)(2)(E)
of the Code.

   E. As an inducement to Acquiror to enter into this Agreement, as of the date
hereof, certain of the officers, directors and ten percent (10%) stockholders
of Target shall enter into an agreement (the "Affiliates Agreement"), which
provides, among other things, that such person shall comply with Rule 145 under
the Securities Act of 1933, as amended (the "Act").

   F. Further, as an inducement to Acquiror to enter into this Agreement, as of
the date of this Agreement certain of the stockholders of Target shall enter
into an agreement (the "Target Voting Agreement"), which provides, among other
things, that such stockholders shall vote the shares of Target's Capital Stock
owned by such person to approve the Merger and against any competing proposals.

   G. As an inducement to Target to enter into this Agreement, as of the date
of this Agreement, certain of the stockholders of Acquiror shall enter into an
agreement (the "Acquiror Voting Agreement"), which provides, among other
things, that such stockholders shall vote the shares of Acquiror's Common Stock
owned by such person to approve the Merger and against any competing proposals.

   NOW, THEREFORE, in consideration of the mutual covenants and representations
set forth herein, and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged the parties hereto, intending
to be legally bound hereby, agree as follows:

                                      A-1

                                   ARTICLE I

                                   THE MERGER

   1.1 The Merger. At the Effective Time (as defined in Section 1.2) and
subject to and upon the terms and conditions of this Agreement, Merger Sub
shall be merged with and into Target, in accordance with the Delaware General
Corporation Law ("DGCL" or "Delaware Law"), the separate corporate existence of
Merger Sub shall cease and Target shall continue as the surviving corporation.
Target as the surviving corporation after the Merger is hereinafter sometimes
referred to as the "Surviving Corporation."

   1.2 Closing; Effective Time. The closing of the transactions contemplated
hereby (the "Closing") shall take place as soon as practicable after the
satisfaction or waiver of each of the conditions set forth in Article VI
hereof, but in any event no later than May 30, 2001 (the date on which the
Closing shall occur, the "Closing Date"). The Closing shall take place at the
offices of Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP, 2700
Via Fortuna, Suite 300, Austin, Texas 78746-7996. On the Closing Date, the
parties hereto shall cause the Merger to be consummated by filing the
Certificate of Merger, attached hereto as Exhibit A, with the Secretary of
State of the State of Delaware (the time and date of such filing being the
"Effective Time" and the "Effective Date," respectively).

   1.3 Effect of the Merger. At the Effective Time, the effect of the Merger
shall be as provided in this Agreement, the Certificate of Merger and the
applicable provisions of the DGCL. Without limiting the generality of the
foregoing, and subject thereto, at the Effective Time, all the property,
rights, privileges, powers and franchises of Target shall vest in the Surviving
Corporation, and all debts, liabilities and duties of Target shall become the
debts, liabilities and duties of the Surviving Corporation.

   1.4 Certificate of Incorporation; Bylaws.

     (a) At the Effective Time, the Certificate of Incorporation of Merger
  Sub, as in effect immediately prior to the Effective Time, shall become the
  Certificate of Incorporation of the Surviving Corporation until thereafter
  amended as provided by Delaware Law and such Certificate of Incorporation;
  provided, however, that Article I of the Certificate of Incorporation shall
  be amended to read as follows: "The name of the corporation is Ashford-
  Guild Art Corporation."

     (b) The Bylaws of Merger Sub, as in effect immediately prior to the
  Effective Time, shall become the Bylaws of the Surviving Corporation until
  thereafter amended.

   1.5 Directors and Officers. At the Effective Time, the directors of Merger
Sub immediately prior to the Effective Time shall be the directors of the
Surviving Corporation, to hold office until such time as such directors resign,
are removed or their respective successors are duly elected or appointed and
qualified. The officers of Merger Sub immediately prior to the Effective Time
shall be the officers of the Surviving Corporation, to hold office until such
time as such officers resign, are removed or their respective successors are
duly elected or appointed and qualified.

   1.6 Effect on Capital Stock. By virtue of the Merger and without any action
on the part of Acquiror, Merger Sub, Target or the holders of any of Target's
securities:

     (a) Conversion of Target Capital Stock. The number of shares of Acquiror
  Common Stock to be issued in exchange for the acquisition by Acquiror of
  all outstanding shares of Target Capital Stock shall be 7,141,400 (the
  "Merger Consideration"). No adjustment shall be made in the number of
  shares of Acquiror Common Stock issued in the Merger for any reason, other
  than pursuant to Section 1.6(g), including without limitation, as a result
  of (x) any increase or decrease in the market price of Acquiror Common
  Stock prior to the Effective Time or (y) any cash proceeds received by
  Target from the date hereof to the Closing Date pursuant to the exercise of
  currently outstanding warrants to purchase shares of Target Common Stock
  (the "Target Warrants") or upon the exercise of currently outstanding
  options to purchase shares of Target Common Stock (the "Target Options").
  Subject to the terms and conditions of

                                      A-2
<PAGE>

  this Agreement and the Certificate of Merger as of the Effective Time, by
  virtue of the Merger and without any action on the part of the holder of
  any shares of Target Capital Stock, each share of Target Common Stock and
  Target Preferred Stock issued and outstanding immediately prior to the
  Effective Time (other than shares to be cancelled pursuant to Section
  1.6(c) and Dissenting Shares (as defined below)) shall be converted and
  exchanged for such number of shares of Acquiror Common Stock as shall be
  determined in accordance with the exchange ratios (the "Exchange Ratios")
  set forth in (i) Exhibit B-1 hereto in the event an amendment to Section
  2(d)(i) of the Restated Certificate of Incorporation of the Target (the
  "Amendment") is approved by the requisite vote(s) of the Target Capital
  Stock and the value of the Merger Consideration is less than the aggregate
  amount of the liquidation preferences of the Series B Preferred Stock, the
  Series C-1 Preferred Stock and the Series D Preferred Stock, such Amendment
  to add a new paragraph immediately following the existing Section 2(d)(i)
  to read as follows:

  "For purposes of this Section 2, and notwithstanding any contrary provision
  of this Section 2 or as set forth elsewhere herein, the merger (the
  "Merger") of the corporation with Ashford-Guild Art Corporation, a Delaware
  corporation (the "Merger Sub") pursuant to the terms and conditions of that
  certain Agreement and Plan of Reorganization by and among Ashford.com,
  Inc., a Delaware corporation ("Ashford"), the corporation and Merger Sub
  dated January 3, 2001 (the "Merger Agreement") shall be deemed to be a
  liquidation, dissolution and winding up of the corporation, and the
  liquidation preferences and the consideration to be received by each holder
  of Series A Preferred Stock, Series B Preferred Stock, Series C-1 Preferred
  Stock and Series D Preferred Stock in connection with the Merger shall be
  determined as set forth in Exhibit B-1 of the Merger Agreement if the value
  of the Merger Consideration (as defined in the Merger Agreement) is less
  than the aggregate amount of the liquidation preferences of the Series B
  Preferred Stock, the Series C-1 Preferred Stock and the Series D Preferred
  Stock as such series are entitled to pursuant to Section 2(a)."

  (ii) Exhibit B-2 hereto in the event the Amendment is not so approved and
  the value of the Merger Consideration is less than the aggregate amount of
  the liquidation preferences of the Series B Preferred Stock, the Series C-1
  Preferred Stock and the Series D Preferred Stock and (iii) Exhibit B-3
  hereto if the Merger Consideration is greater than the aggregate amount of
  the liquidation preferences of the Series B Preferred Stock, the Series C-1
  Preferred Stock and the Series D Preferred Stock.

     (b) Dissenter's Rights. If any holder of Target Capital Stock dissents
  from the consummation of this Agreement in accordance with the DGCL, and if
  such holder has complied with the requirements of Subchapter IX of the DGCL
  (a "Target Dissenting Stockholder"), then, notwithstanding anything
  contained in this Agreement to the contrary, each share of Target Capital
  Stock held by a Target Dissenting Stockholder (the "Dissenting Shares")
  shall not be converted into or represent the right to receive shares of the
  Acquiror Common Stock pursuant to Section 1.6, but such Target Dissenting
  Stockholder shall be entitled to the rights specified in the DGCL;
  provided, however, that if a Target Dissenting Stockholder withdraws his,
  her or its dissent (or if a person ceases to be a Target Dissenting
  Stockholder because such person fails to comply with the requirements of
  Subchapter IX of the DGCL), then the Target Capital Stock held by such
  person shall be deemed to be converted as of the Effective Time, into the
  Acquiror Common Stock as set forth in Section 1.6, without any interest
  thereon, and such shares of Target Capital Stock shall no longer be deemed
  to be Dissenting Shares.

     (c) Cancellation of Target Capital Stock Owned by Acquiror or Target. At
  the Effective Time, each share of Target Capital Stock that is owned by
  Target as treasury stock, each share of Target Capital Stock owned by
  Acquiror or any direct or indirect wholly owned subsidiary of Acquiror or
  of Target immediately prior to the Effective Time shall be canceled and
  extinguished without any conversion thereof.

     (d) Target Stock Option Plans. At the Effective Time, the Guild.com,
  Inc. Stock Option Plan, as amended and restated August 29, 2000 (the
  "Target Stock Option Plan"), and all options to purchase Target Common
  Stock then outstanding under the Target Stock Option Plan, shall be assumed
  by Acquiror in accordance with Section 5.13.

                                      A-3
<PAGE>

     (e) Target Warrants. At the Effective Time, all outstanding Target
  Warrants that do not terminate by their terms shall be assumed by Acquiror
  in accordance with Section 5.13.

     (f) Capital Stock of Merger Sub. At the Effective Time, each share of
  Common Stock, $.001 par value, of Merger Sub, issued and outstanding
  immediately prior to the Effective Time shall be converted into and
  exchanged for one validly issued, fully paid and nonassessable share of
  Common Stock, $.001 par value, of the Surviving Corporation. Each stock
  certificate of Merger Sub evidencing ownership of any such shares shall
  continue to evidence ownership of such shares of capital stock of the
  Surviving Corporation.

     (g) Adjustments to Exchange Ratio. The Exchange Ratios in Exhibit B-1,
  Exhibit B-2, and Exhibit B-3, as applicable, shall be adjusted to reflect
  fully the effect of any stock split, reverse split, stock dividend
  (including any dividend or distribution of securities convertible into
  Acquiror Common Stock or Target Capital Stock), any extraordinary dividend,
  reorganization, recapitalization or other like change with respect to
  Acquiror Common Stock or Target Capital Stock occurring after the date
  hereof and prior to the Effective Time.

     (h) Fractional Shares. No fraction of a share of Acquiror Common Stock
  will be issued, but in lieu thereof each holder of shares of Target Capital
  Stock who would otherwise be entitled to a fraction of a share of Acquiror
  Common Stock (after aggregating all fractional shares of Acquiror Common
  Stock to be received by such holder) shall receive from Acquiror an amount
  of cash (rounded to the nearest whole cent) equal to the product of (i)
  such fraction, multiplied by (ii) the average of the closing prices for a
  share of Acquiror Common Stock as quoted on the NASDAQ National Market for
  the twenty (20) trading days immediately preceding and ending on the last
  trading day before the Closing Date.

     (i) Dissenter's Rights. Any Dissenting Shares shall not be converted
  into Acquiror Common Stock and shall not receive any cash but shall instead
  be converted into the right to receive such consideration as may be
  determined to be due with respect to such Dissenting Shares pursuant to
  Delaware Law. Target agrees that, except with the prior written consent of
  Acquiror, or as required under Delaware Law, it will not prior to the
  Effective Time make any payment with respect to, or settle or offer to
  settle, any claim, demand, or other liability with respect to any
  Dissenting Shares. Each Target Dissenting Stockholder who, pursuant to the
  provisions of Delaware Law, becomes entitled to payment of the value for
  shares of Target Capital Stock shall receive payment therefor (but only
  after the value therefor shall have been agreed upon or finally determined
  pursuant to such provisions). If, after the Effective Time, any Dissenting
  Shares shall lose their status as Dissenting Shares, Acquiror shall issue
  and deliver, upon surrender by such stockholder of certificate or
  certificates representing shares of Target Capital Stock, the number of
  shares of Acquiror Common Stock to which such stockholder would otherwise
  be entitled under this Section 1.6 and the Certificate of Merger.

   1.7 Surrender of Certificates.

   (a) Exchange Agent. ChaseMellon Shareholder Services, L.L.C. shall act as
exchange agent (the "Exchange Agent") in the Merger.

   (b) Acquiror to Provide Common Stock and Cash. Promptly after the Effective
Time, Acquiror shall issue and make available to the Exchange Agent for
exchange in accordance with this Article I (i) the shares of Acquiror Common
Stock issuable pursuant to Section 1.6(a) in exchange for shares of Target
Capital Stock outstanding immediately prior to the Effective Time and (ii) cash
in an amount sufficient to permit payment of cash in lieu of fractional shares
pursuant to Section 1.6(h).

   (c) Exchange Procedures. Promptly after the Effective Time, Acquiror shall
cause to be mailed to each holder of record of a certificate or certificates
(the "Certificates") which immediately prior to the Effective Time represented
outstanding shares of Target Capital Stock, whose shares were converted into
the right to receive shares of Acquiror Common Stock (and cash in lieu of
fractional shares) pursuant to Section 1.6 (i) a letter of transmittal (which
shall specify that delivery shall be effected, and risk of loss and title to
the

                                      A-4
<PAGE>

Certificates shall pass, only upon receipt of the Certificates by the Exchange
Agent, and shall be in such form and have such other provisions as Acquiror may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for certificates representing shares of Acquiror
Common Stock (and cash in lieu of fractional shares). Upon surrender of a
Certificate for cancellation to the Exchange Agent, together with such letter
of transmittal, duly completed and validly executed in accordance with the
instructions thereto, the holder of such Certificate shall be entitled to
receive in exchange therefor a certificate representing the number of whole
shares of Acquiror Common Stock and payment in lieu of fractional shares which
such holder has the right to receive pursuant to Section 1.6, and the
Certificate so surrendered shall forthwith be canceled. Until so surrendered,
each outstanding Certificate that, prior to the Effective Time, represented
shares of Target Capital Stock will be deemed from and after the Effective
Time, for all corporate purposes, other than the payment of dividends, to
evidence the ownership of the number of full shares of Acquiror Common Stock
into which such shares of Target Capital Stock shall have been so converted and
the right to receive an amount in cash in lieu of the issuance of any
fractional shares in accordance with Section 1.6(h).

   (d) Distributions with Respect to Unexchanged Shares. No dividends or other
distributions with respect to Acquiror Common Stock with a record date after
the Effective Time shall be paid to the holder of any unsurrendered Certificate
with respect to the shares of Acquiror Common Stock represented thereby until
the holder of record of such Certificate surrenders such Certificate. Subject
to applicable law, following surrender of any such Certificate, there shall be
paid to the record holder of the certificates representing whole shares of
Acquiror Common Stock issued in exchange therefor, without interest, at the
time of such surrender, the amount of any such dividends or other distributions
with a record date after the Effective Time which would have been previously
payable (but for the provisions of this Section 1.7(d)) with respect to such
shares of Acquiror Common Stock.

   (e) Transfers of Ownership. If any certificate for shares of Acquiror Common
Stock is to be issued in a name other than that in which the Certificate
surrendered in exchange therefor is registered, it shall be a condition of the
issuance thereof that the Certificate so surrendered is properly endorsed or
accompanied by a stock power duly endorsed and otherwise in proper form for
transfer and that the person requesting such exchange will have paid to
Acquiror or any agent designated by it any transfer or other taxes required by
reason of the issuance of a certificate for shares of Acquiror Common Stock in
any name other than that of the registered holder of the Certificate
surrendered, or established to the satisfaction of Acquiror or any agent
designated by it that such tax has been paid or is not payable.

   (f) No Liability. Notwithstanding anything to the contrary in this Section

pursuant to any applicable abandoned property, escheat or similar law.

   (g) Dissenting Shares. The provisions of this Section 1.7 shall also apply
to Dissenting Shares that lose their status as such, except that the
obligations of Acquiror under this Section 1.7 shall commence on the date of

in exchange for such shares the number of shares of Acquiror Common Stock (and
cash in lieu of fractional shares) to which such holder is entitled pursuant to

satisfaction of all rights pertaining to such shares of Target Capital Stock,
and there shall be no further registration of transfers on the records of the

against any claim that may be made against Acquiror, the Surviving Corporation
or the Exchange Agent with respect to the Certificates alleged to have been
lost, stolen or destroyed.

<PAGE>

   2.6 Litigation. There is no action, suit, proceeding or investigation
pending or, to Target's knowledge, currently threatened against Target that
questions the validity of this Agreement or any of the Target Transaction
Documents, or the right of Target to enter into such agreements, or to
consummate the transactions contemplated hereby or thereby, or that might
result, either individually or in the aggregate, in any Material Adverse Effect
on Target, or any change in the current equity ownership of Target, nor is
Target aware that there is any basis for the foregoing. The foregoing includes,
without limitation, actions, suits, proceedings or investigations pending or
threatened (or any basis therefor known to Target) involving the prior
employment of any of Target's employees, their use in connection with Target's
business of any information or techniques allegedly proprietary to any of their
former employers, or their obligations under any agreements with prior
employers. Target is not a party or subject to the provisions of any order,
writ, injunction, judgment or decree of any court or government agency or
instrumentality. There is no action, suit, proceeding or investigation by
Target currently pending or that Target intends to initiate.

   2.7 Patents and Trademarks. Target has sufficient title and ownership of or
exclusive licenses to all patents, trademarks, service marks, trade names,
copyrights, trade secrets, information, proprietary rights and processes
necessary for its business as now conducted and as proposed to be conducted
without any conflict with or infringement of the rights of others, except for
such items as have yet to be conceived or developed or that are expected to be
available for licensing on reasonable terms from third parties. The Target
Disclosure Schedule contains a complete list of patents and pending patent
applications, trademarks and pending trademark applications and copyrights and
pending copyright applications of Target. There are no outstanding options,
licenses, or agreements of any kind relating to the foregoing, nor is Target
bound by or a party to any options, licenses or agreements of any kind with
respect to the patents, trademarks, service marks, trade names, copyrights,
trade secrets, licenses, information, proprietary rights and processes of any
other person or entity, except, in either case, for standard end-user, object
code, internal-use software license and support/maintenance agreements. Target
has not received any communications alleging that Target has violated or, by
conducting its business as proposed, would violate any of the patents,
trademarks, service marks, trade names, copyrights or trade secrets or other
proprietary rights of any other person or entity. Target is not aware that any
of its employees is obligated under any contract (including licenses, covenants
or commitments of any nature) or other agreement, or subject to any judgment,
decree or order of any court or administrative agency, that would interfere
with the use of his or her best efforts to promote the interests of Target or
that would conflict with Target's business as proposed to be conducted. Neither
the execution nor delivery of this Agreement or any of the Target Transaction
Documents, nor the carrying on of Target's business by the employees of Target,
nor the conduct of Target's business as proposed, will, to the best of Target's
knowledge, conflict with or result in a breach of the terms, conditions or
provisions of, or constitute a default under, any contract, covenant or
instrument under which any of such employees is now obligated. Target does not
believe it is or will be necessary to utilize any inventions of any of its
employees (or people it currently intends to hire) made prior to or outside the
scope of their employment by Target.

   2.8 Compliance with Other Instruments. Target is not in violation or default
of any provision of its Certificate of Incorporation or Bylaws, or in any
material respect of any instrument, judgment, order, writ, decree or contract
to which it is a party or by which it is bound, or, to the best of its
knowledge, of any provision of any federal or state statute, rule or regulation
applicable to Target. The execution, delivery and performance of this Agreement
and the Target Transaction Documents, and the consummation of the transactions
contemplated hereby and thereby will not result in any such violation or be in
conflict with or constitute, with or without the passage of time and giving of
notice, either a default under any such provision, instrument, judgment, order,
writ, decree or contract or an event that results in the creation of any lien,
charge or encumbrance upon any assets of Target or the suspension, revocation,
impairment, forfeiture, or nonrenewal of any material permit, license,
authorization, or approval applicable to Target, its business or operations or
any of its assets or properties.

advances to any person, other than ordinary advances for travel and similar

the purpose of meeting the individual minimum dollar amounts of such
subsections.

the sale, conveyance or disposition of all or substantially all of the assets
of Target or a transaction or series of related transactions in which more than
fifty percent (50%) of the voting power of Target is disposed of, or (iii)
regarding any other form of acquisition, liquidation, dissolution or winding up
of Target.

   2.10 Related Party Transactions. No employee, officer, or director of Target
or member of his or her immediate family is indebted to Target, nor is Target
indebted (or committed to make loans or extend or guarantee credit) to any of
them. To the best of Target's knowledge, none of such persons has any direct or
indirect ownership interest in any firm or corporation with which Target is
affiliated or with which Target has a business relationship, or any firm or
corporation that competes with Target, except that employees, officers, or
directors of Target and members of their immediate families may own stock in
publicly traded companies that may compete or have a business relationship with
Target. No member of the immediate family of any officer or director of Target
is directly or indirectly interested in any material contract with Target.

   2.11 Permits. Target has all franchises, permits, licenses, and any similar
authority necessary for the conduct of its business as now being conducted by
it, the lack of which could have a Material Adverse Effect on Target, and to
Target's knowledge it can obtain, without undue burden or expense, any similar
authority for the conduct of its business as planned to be conducted. Target is
not in default in any material respect under any of such franchises, permits,
licenses, or other similar authority.

   2.12 Environmental and Safety Laws. To the best of its knowledge, Target is
not in violation of any applicable statute, law or regulation relating to the
environment or occupational health and safety, and to the

order to comply with any such existing statute, law or regulation.

   2.13 Manufacturing and Marketing Rights. Target has not granted rights to

other person and is not bound by any agreement that affects Target's exclusive
right to develop, manufacture, assemble, distribute, market or sell its
products.

Target are in the form previously provided to counsel for the Acquiror.

   2.16 Title to Property and Assets. Target owns its property and assets free
and clear of all mortgages, liens, loans and encumbrances, except such
encumbrances and liens that arise in the ordinary course of business and do not
materially impair Target's ownership or use of such property or assets. With
respect to the property and assets it leases, Target is in compliance in all
material respects with such leases and, to the best of its knowledge, holds a
valid leasehold interest free of any liens, claims or encumbrances.

   2.17 Target Financial Statements. Target has delivered to Acquiror Target's
audited financial statements (balance sheet and statement of operations,
statement of changes in stockholders' equity and statement of cash flows,
including notes thereto) at December 31, 1999 and for the fiscal year of Target
then ended (the "Target Audited Financial Statements") and its unaudited
interim financial statements (balance sheet and income statement) at November
30, 2000 and for the eleven-month period then ended (the "Target Interim
Financial Statements", and together with the Target Audited Financial
Statements, the "Target Financial Statements"). The Target Audited Financial
Statements have been prepared in accordance with generally accepted accounting
principles applied on a consistent basis throughout the periods indicated and
with each other (except as indicated in the notes thereto). The Target
Financial Statements fairly present the financial condition and operating
results of Target as of the dates, and for the periods, indicated therein
(subject, in the case of unaudited statements, to normal, recurring year-end
adjustments). Except as set forth in the Target Financial Statements, or in the
notes thereto, Target has no material liabilities, contingent or otherwise,
other than (i) liabilities incurred in the ordinary course of business
subsequent to December 31, 1999 and (ii) obligations under contracts and
commitments incurred in the ordinary course of business and not required under
generally accepted accounting principles to be reflected in the Target
Financial Statements, which, in both cases, individually or in the aggregate,
are not material to the financial condition or operating results of Target.
Except as disclosed in the Target Financial Statements, Target is not a
guarantor or indemnitor of any indebtedness of any other person, firm or
corporation. Target maintains and will continue to maintain a standard system
of accounting established and administered in accordance with generally
accepted accounting principles.

aggregate, materially adverse;

it;

employees, officers or directors, or any members of their immediate families,
other than travel advances and other advances made in the ordinary course of
its business;

   (l) any declaration, setting aside or payment or other distribution in
respect of any of Target's Capital Stock, or any direct or indirect redemption,
purchase or other acquisition of any of such stock by Target;

   (m) to the best of Target's knowledge, any other event or condition of any
character that might materially and adversely affect the assets, properties,
financial condition, operating results or business of Target (as such business
is presently conducted and as it is proposed to be conducted); or

   (n) any agreement or commitment by Target to do any of the things described
in this Section 2.18.

   2.19 Employee Benefit Plans. Target does not sponsor or maintain any
Employee Benefit Plan as defined in the Employee Retirement Income Security Act
of 1974.

   2.20 Tax Returns, Payments and Elections. Target has filed all tax returns
and reports (including information returns and reports) as required by law.
These returns and reports are true and correct in all material respects. Target
has paid all taxes and other assessments due, except those contested by it in
good faith that are listed in the Target Disclosure Schedule or reserved on the
Target Financial Statements. Target has not elected pursuant to the Internal
Revenue Code of 1986, as amended (the "Code"), to be treated as a collapsible
corporation pursuant to Section 341(f) of the Code, nor has it made any other
elections pursuant to the Code (other than elections that relate solely to
methods of accounting, depreciation or amortization) that would have a Material
Adverse Effect on Target. Target has never had any tax deficiency proposed or
assessed against it and has not executed any waiver of any statute of
limitations on the assessment or collection of any tax or governmental charge.
None of Target's federal income tax returns and none of its state income or
franchise tax or sales or use tax returns have ever been audited by
governmental authorities. Since the date of the Target Financial Statements,
Target has not incurred any taxes, assessments or governmental charges other
than in the ordinary course of business and Target has made adequate provisions
on its books of account for all taxes, assessments and governmental charges
with respect to its business, properties and operations for such period. Target
has withheld or collected from each payment (whether in cash or in kind) made
or deemed made to each of its employees, the amount of all taxes (including,
but not limited to, federal income taxes, Federal Insurance Contribution Act
taxes and Federal Unemployment Tax Act taxes) required by applicable law to be
withheld or collected therefrom, and has paid the same to the proper tax
receiving officers or authorized depositories.

bound by or subject to (and none of its assets or properties is bound by or
subject to) any written or oral, express or implied, contract, commitment or
arrangement with any labor union, and no labor union has requested or, to the
best of Target's knowledge, has sought to represent any of the employees,
representatives or agents of Target. There is no strike or other labor dispute
involving Target pending, or to the best of Target's knowledge, threatened,
that could have a Material Adverse Effect on Target, nor is Target aware of any
labor organization activity involving its employees. Target is not aware that
any officer or key employee, or that any group of key employees, intends to
terminate their employment with Target, nor does Target have a present
intention to terminate the employment of any of the foregoing prior to the
Closing. The employment of each officer and employee of Target is terminable at
the will of Target. To the best of its knowledge, Target has complied in all
material respects with all applicable state and federal equal employment
opportunity and other laws related to employment. Target is not a party to or
bound by any currently effective employment contract, deferred compensation
agreement, bonus plan, incentive plan, profit sharing plan, retirement
agreement, or other employee compensation agreement.

information supplied by Target expressly for the purpose of inclusion in the
registration statement (the "Registration Statement") on Form S-4 (or such
other or successor form as shall be appropriate) pursuant to which the issuance

registered with the Securities and Exchange Commission (the "SEC") shall not at
the time the Registration Statement (including any amendments or supplements
thereto) is declared effective by the SEC contain any untrue statement of a
material fact or omit to state any material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading. The written information supplied by Target expressly for the
purpose of inclusion in the proxy statement/prospectus to be sent to the
stockholders of Target and Acquiror in connection with the meetings of Target's
stockholders (the "Target Stockholders Meeting") and Acquiror's stockholders

herein as the "Proxy Statement") shall not, on the date the Proxy Statement is
first mailed to Target's stockholders and Acquiror's stockholders, at the time
of the Target Stockholders Meeting and Acquiror's Stockholders Meeting and at
the Effective Time, contain any untrue statement of a material fact, or omit to
state any material fact necessary in order to make the statements made therein,
in light of the circumstances under which they were made, not misleading. If at
any time prior to the Effective Time any event or information should be
discovered by Target which should be set forth in an amendment to the
Registration Statement or a supplement to the Proxy Statement, Target shall

be.

by this Agreement.

   2.28 Employees. No employee of Target has any agreement or contract, written
or verbal, except as set forth herein, regarding such person's employment with
Target. To the best of Target's knowledge, no employee of Target nor any

                                  ARTICLE III

           REPRESENTATIONS AND WARRANTIES OF ACQUIROR AND MERGER SUB

   Acquiror hereby represents and warrants to Target that, except as set forth
on the disclosure letter attached hereto (the "Acquiror Disclosure Schedule"),
specifically identifying the relevant subparagraph hereof, which Acquiror
Disclosure Schedule is incorporated herein by this reference:

   3.1 Organization, Standing and Power. Each of Acquiror and its subsidiaries
is a corporation duly organized, validly existing and in good standing under
the laws of its jurisdiction of organization. Each of Acquiror and its
subsidiaries has the corporate power to own its properties and to carry on its
business as now being conducted and as proposed to be conducted and is duly
qualified to do business and is in good standing in each jurisdiction in which
the failure to be so qualified and in good standing would have a Material
Adverse Effect on Acquiror. Neither Acquiror nor Merger Sub (or any other
subsidiary) is in violation of any of the

                                      A-13
<PAGE>

provisions of its respective, Certificate of Incorporation or Bylaws. Acquiror
is the owner of all outstanding shares of capital stock of each of its
subsidiaries and all such shares are duly authorized, validly issued, fully
paid and nonassessable. All of the outstanding shares of capital stock of each
such subsidiary are owned by Acquiror free and clear of all liens, charges,
claims or encumbrances or rights of others.

   3.2 Capitalization. The authorized capital stock of the Acquiror consists of
(a) 100,000,000 shares of Acquiror Common Stock, of which 46,644,246 shares
were issued and outstanding as of the date hereof, and (b) 10,000,000 shares of
Preferred Stock, $.001 par value per share, of which no shares are issued or
outstanding. As of the date hereof, Acquiror has issued approximately 6,900,000
options to acquire shares of Acquiror's Common Stock pursuant to Acquiror's
1998 Stock Incentive Plan, 1999 Equity Incentive Plan and 2000 Non-Officer
Stock Plan (together the "Acquiror Stock Option Plans") and warrants to acquire
853,636 shares of Acquiror's Common Stock. Other than the options and warrants
identified above and as previously disclosed to Target, there are no
outstanding rights or agreements for the purchase or acquisition from Acquiror
of any shares of its capital stock. All of the issued and outstanding shares of
Acquiror Common Stock are duly authorized, validly issued, fully paid,
nonassessable and free of all preemptive rights. All of the shares of Acquiror
Common Stock to be issued in connection with the Merger, upon exercise of the
Target Options and upon exercise of the Target Warrants, will be, when issued
in accordance with this Agreement and the Target Stock Option Plan, duly
authorized, validly issued, fully paid, nonassessable and free of all
preemptive rights.

   3.3 Authority.

   (a) Each of Acquiror and Merger Sub has all requisite corporate power and
authority to enter into this Agreement, the Target Voting Agreements and all
other agreements referred to herein to which Acquiror is a party (the "Acquiror
Transaction Documents") and to consummate the transactions contemplated hereby
and thereby. The execution and delivery of this Agreement and the other
Acquiror Transaction Documents and the consummation of the transactions
contemplated hereby and thereby have been or will be, prior to the Effective
Time, duly authorized by all necessary corporate action on the part of each of
Acquiror and Merger Sub. This Agreement and the other Acquiror Transaction
Documents have been duly executed and delivered by each of Acquiror and Merger
Sub and constitute or will constitute, upon approval of the Acquiror's
stockholders, the valid and legally binding obligations of each of Acquiror and
Merger Sub, enforceable in accordance with their respective terms, except (i)
as limited by applicable bankruptcy, insolvency, reorganization, moratorium,
and other laws of general application affecting enforcement of creditors'
rights generally and (ii) as limited by laws relating to the availability of
specific performance, injunctive relief, or other equitable remedies.

   (b) The execution and delivery of this Agreement and the other Acquiror
Transaction Documents do not, and the consummation of the transactions
contemplated hereby and thereby will not, conflict with, or result in any
violation of, or default under (with or without notice or lapse of time, or
both), or give rise to a right of termination, cancellation or acceleration of
any obligation or loss of a benefit under (i) any provision of the Certificate
of Incorporation or Bylaws of Acquiror or any of its subsidiaries, as amended,
or (ii) any material mortgage, indenture, lease, contract or other agreement or
instrument, permit, concession, franchise, license, judgment, order, decree,
statute, law, ordinance, rule or regulation applicable to Acquiror or any of
its subsidiaries or their properties or assets.

   (c) No consent, approval, order or authorization of, or registration,
declaration or filing with, any federal, state or local governmental authority,
is required by or with respect to Acquiror or any of its subsidiaries in
connection with the execution and delivery of this Agreement or the other
Acquiror Transaction Documents by Acquiror or the consummation by Acquiror of
the transactions contemplated hereby or thereby, except for (i) the filing of
the Certificate of Merger as provided in Section 1.2, (ii) any filings as may
be required under applicable state securities laws and the securities laws of
any foreign country, (iii) the filing with the NASDAQ National Market of a
Notification Form for Listing of Additional Shares with respect to the shares
of Acquiror Common Stock issuable upon conversion of the Target Capital Stock
in the Merger, upon exercise of the Target Options and upon exercise of the
Target Warrants assumed by Acquiror, and the filing of a registration statement
on Form S-8 covering shares issued upon exercise of the Target Options and the
Target Warrants, (iv)

                                      A-14
<PAGE>

the filing with the SEC of a Registration Statement on Form S-4 with respect to
the shares of Acquiror Common Stock to be issued in the Merger, and (v) such
other consents, authorizations, filings, approvals and registrations which, if
not obtained or made, would not have a Material Adverse Effect on Acquiror and
would not prevent, materially alter or delay any of the transactions
contemplated by this Agreement or the other Acquiror Transaction Documents.

   3.4 SEC Documents. Acquiror has furnished to Target a true and complete copy
of each statement, report, registration statement (with the prospectus in the
form filed pursuant to Rule 424(b) of the Act), definitive proxy statement, and
other filings filed with the SEC by Acquiror since April 1, 2000 and, prior to
the Effective Time, Acquiror will have furnished Target with true and complete
copies of any additional documents filed with the SEC by Acquiror prior to the
Effective Time (collectively, the "Acquiror SEC Documents"). All documents
required to be filed as exhibits to the Acquiror SEC Documents have been so
filed, and all material contracts so filed as exhibits are in full force and
effect, except those which have expired in accordance with their terms, and
neither Acquiror nor any of its subsidiaries is in default thereunder, except
where default would not reasonably be expected to have a Material Adverse
Effect on Acquiror. As of their respective filing dates, the Acquiror SEC
Documents complied in all material respects with the requirements of the
Securities Exchange Act of 1934 (the "Exchange Act") and the Act, and none of
the Acquiror SEC Documents contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements made therein, in light of the circumstances in which they
were made, not misleading, except to the extent corrected by a subsequently
filed Acquiror SEC Document which was filed prior to the date hereof. The
financial statements of Acquiror, including the notes thereto, included in the
Acquiror SEC Documents (the "Acquiror Financial Statements") were complete and
correct in all material respects as of their respective dates, complied as to
form in all material respects with applicable accounting requirements and with
the published rules and regulations of the SEC with respect thereto as of their
respective dates, and have been prepared in accordance with generally accepted
accounting principles applied on a basis consistent throughout the periods
indicated and consistent with each other (except as may be indicated in the
notes thereto or, in the case of unaudited statements included in Quarterly
Reports on Form 10-Qs, as permitted by Form 10-Q of the SEC). The Acquiror
Financial Statements fairly present the consolidated financial condition and
operating results of Acquiror and its subsidiaries at the dates and during the
periods indicated therein (subject, in the case of unaudited statements, to
normal, recurring year-end adjustments). Acquiror maintains a standard system
of accounting established and administered in accordance with generally
accepted accounting principles. The unaudited interim financial statements
(balance sheet and income statement) of Acquiror at November 30, 2000 and for
the eight-month period then ended are complete and correct in all material
respects as of such date and for such period, were prepared in accordance with
generally accepted accounting principles applied on a basis consistent
throughout the period indicated therein and fairly present the financial
condition and operating results of Acquiror as of such date and for the period
covered thereby. Since the date of the most recent Quarterly Report on Form 10-
Q filed by Acquiror with the SEC, other than as previously disclosed to Target
there has been no Material Adverse Effect on Acquiror, other than fluctuations
in the market price of Acquiror's Common Stock as quoted on the NASDAQ National
Market.

   3.5 Tax Returns, Payments and Elections. Acquiror has filed all tax returns
and reports (including information returns and reports) as required by law.
These returns and reports are true and correct in all material respects.
Acquiror has paid all taxes and other assessments due, except those contested
by it in good faith that are listed in the Acquiror Disclosure Schedule or
reserved on the Acquiror Financial Statements. Acquiror has not elected
pursuant to the Code, to be treated as a collapsible corporation pursuant to
Section 341(f) of the Code, nor has it made any other elections pursuant to the
Code (other than elections that relate solely to methods of accounting,
depreciation or amortization) that would have a Adverse Material Effect on
Acquiror. Acquiror has never had any tax deficiency proposed or assessed
against it and has not executed any waiver of any statute of limitations on the
assessment or collection of any tax or governmental charge. None of Acquiror's
federal income tax returns and none of its state income or franchise tax or
sales or use tax returns have ever been audited by governmental authorities.
Since the date of the Acquiror Financial Statements, Acquiror has not incurred
any taxes, assessments or governmental charges other than in the ordinary
course of

                                      A-15
<PAGE>

business and Acquiror has made adequate provisions on its books of account for
all taxes, assessments and governmental charges with respect to its business,
properties and operations for such period. Acquiror has withheld or collected
from each payment (whether in cash or in kind) made or deemed made to each of
its employees, the amount of all taxes (including, but not limited to, federal
income taxes, Federal Insurance Contribution Act taxes and Federal Unemployment
Tax Act taxes) required by applicable law to be withheld or collected
therefrom, and has paid the same to the proper tax receiving officers or
authorized depositories.

   3.6 Patents and Trademarks. Acquiror has sufficient title and ownership of
or exclusive licenses to all patents, trademarks, service marks, trade names,
copyrights, trade secrets, information, proprietary rights and processes
necessary for its business as now conducted and as proposed to be conducted
without any conflict with or infringement of the rights of others, except for
such items as have yet to be conceived or developed or that are expected to be
available for licensing on reasonable terms from third parties. The Acquiror
Disclosure Schedule contains a complete list of patents and pending patent
applications, trademarks and pending trademark applications and copyrights and
pending copyright applications of Acquiror. There are no outstanding options,
licenses, or agreements of any kind relating to the foregoing, nor is Acquiror
bound by or a party to any options, licenses or agreements of any kind with
respect to the patents, trademarks, service marks, trade names, copyrights,
trade secrets, licenses, information, proprietary rights and processes of any
other person or entity, except, in either case, for standard end-user, object
code, internal-use software license and support/maintenance agreements.
Acquiror has not received any communications alleging that Acquiror has
violated or, by conducting its business as proposed, would violate any of the
patents, trademarks, service marks, trade names, copyrights or trade secrets or
other proprietary rights of any other person or entity. Acquiror is not aware
that any of its employees is obligated under any contract (including licenses,
covenants or commitments of any nature) or other agreement, or subject to any
judgment, decree or order of any court or administrative agency, that would
interfere with the use of his or her best efforts to promote the interests of
Acquiror or that would conflict with Acquiror's business as proposed to be
conducted. Neither the execution nor delivery of this Agreement or any of the
Acquiror Transaction Documents, nor the carrying on of Acquiror's business by
the employees of Acquiror, nor the conduct of Acquiror's business as proposed,
will, to the best of Acquiror's knowledge, conflict with or result in a breach
of the terms, conditions or provisions of, or constitute a default under, any
contract, covenant or instrument under which any of such employees is now
obligated. Acquiror does not believe it is or will be necessary to utilize any
inventions of any of its employees (or people it currently intends to hire)
made prior to or outside the scope of their employment by Acquiror.

   3.7 Registration Statement. The written information supplied by Acquiror and
Merger Sub expressly for the purpose of inclusion in the Registration Statement
shall not, at the time the Registration Statement (including any amendments or
supplements thereto) is declared effective by the SEC, contain any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. The written information supplied by Acquiror
expressly for the purpose of inclusion in the Proxy Statement shall not, on the
date the Proxy Statement is first mailed to Target's stockholders and
Acquiror's stockholders, at the time of the Target Stockholders Meeting and
Acquiror Stockholders Meeting and at the Effective Time, contain any untrue
statement of a material fact, or omit to state any material fact necessary in
order to make the statements made therein, in light of the circumstances under
which they were made, not misleading. If at any time prior to the Effective
Time any event or information should be discovered by Acquiror which should be
set forth in an amendment to the Registration Statement or a supplement to the
Proxy Statement, Acquiror shall promptly inform Target. Notwithstanding the
foregoing, neither Acquiror nor Merger Sub make any representation, warranty or
covenant with respect to any information supplied by Target that is contained
in any of the foregoing documents.

   3.8 Litigation. There is no private or governmental action, suit,
proceeding, claim, arbitration or investigation pending before any agency,
court or tribunal, foreign or domestic, or, to the knowledge of Acquiror,
threatened against Acquiror or any of its respective properties or any of its
respective officers or directors (in their capacities as such) that,
individually or in the aggregate, could reasonably be expected to

                                      A-16
<PAGE>

have a Material Adverse Effect on Acquiror or on the transactions contemplated
hereby. There is no judgment, decree or order against Acquiror or, to the
knowledge of Acquiror, any of its respective directors or officers (in their
capacities as such) that could prevent, enjoin, or materially alter or delay
any of the transactions contemplated by this Agreement, or that could
reasonably be expected to have a Material Adverse Effect on Acquiror.

   3.9 Brokers. Acquiror has no contract, arrangement or understanding with any
broker, finder or similar agent with respect to the transactions contemplated
by this Agreement.

   3.10 Compliance with Laws. Acquiror has complied with, is not in violation
of, and has not received any notices of violation with respect to, any federal,
state, local or foreign statute, law or regulation with respect to the conduct
of its business, or the ownership or operation of its business, except for such
violations or failures to comply as could not be reasonably expected to have a
Material Adverse Effect on Acquiror.

   3.11 Merger Sub. Merger Sub is a direct, wholly-owned subsidiary of
Acquiror, was formed solely for the purpose of engaging in the transactions
contemplated hereby, has engaged in no other business activities and has
conducted its operations only as contemplated hereby. Merger Sub has no
liabilities or obligations of any nature, contingent or otherwise, other than
those related to the transactions contemplated hereby.

   3.12 Representations Complete. None of the representations or warranties
made by Acquiror herein or in any Schedule hereto, including the Acquiror
Disclosure Schedule, or certificate furnished by Acquiror pursuant to this
Agreement, when all such documents are read together in their entirety,
contains or will contain at the Effective Time any untrue statement of a
material fact, or omits or will omit at the Effective Time to state any
material fact necessary in order to make the statements contained herein or
therein, in the light of the circumstances under which made, not misleading.

                             ADDITIONAL AGREEMENTS

   5.1 No Solicitation.

   (a) From and after the date of this Agreement until the earlier of the
Effective Time or the termination of this Agreement pursuant to Article VII,
Target shall not, directly or indirectly, through any officer, director,
employee, representative or agent, (i) solicit, initiate, or encourage any
inquiries or proposals that constitute, or could reasonably be expected to lead
to, a proposal or offer for a merger, consolidation, business combination, sale
of all or substantially all of the assets, sale of shares of capital stock
(including without limitation by way of a tender offer) or similar transactions
involving Target, other than the transactions contemplated by this Agreement
(any of the foregoing inquiries or proposals being referred to in this
Agreement as a "Takeover Proposal"), (ii) engage in negotiations or discussions
concerning, or provide any non-public information to any person or entity
relating to, any Takeover Proposal, or (iii) agree to, approve or recommend any
Takeover Proposal; provided, however, that if, at any time prior to the
Effective Time, the Board of Directors of the Target or Acquiror, as the case
may be, determines in good faith, after consultation with outside counsel, that
its fiduciary obligations to its respective stockholders under applicable law
so requires, Target or Acquiror, as the case may be, in response to a Takeover
Proposal which was not solicited by Target or Acquiror, as the case may be,
subsequent to the date hereof (A) may furnish to any person information with
respect to Target or Acquiror, as the case may be, pursuant to a customary
confidentiality agreement, (B) may participate in negotiations regarding such
Takeover Proposal and (C) subject to full compliance with this Section 5.1, may
recommend a proposal to its stockholders which the Board of Directors of Target
or Acquiror, as the case may be, determines in its good faith judgment to be
more favorable to Target or Acquiror, as the case may be (a "Superior
Proposal"); provided, however that such party notifies the other within 24
hours of receipt of any Takeover Proposal.

   (b) Target shall notify Acquiror immediately (in any event, no later than 24
hours) after receipt by Target (or its advisors or agents) of any Takeover
Proposal or any request for information in connection with a Takeover Proposal
or for access to the properties, books or records of Target by any person or
entity that informs Target that it is considering making, or has made, a
Takeover Proposal. Such notice by Target shall be made orally and in writing
and shall indicate in reasonable detail the identity of the offeror and the
terms and conditions of such proposal, inquiry or contact.

   (c) Except as set forth in this Section 5.1, neither the Board of Directors
of Target or Acquiror, as the case may be, nor any committee thereof shall (i)
withdraw or modify, or propose publicly to withdraw or modify, in

                                      A-20
<PAGE>

a manner adverse to the other party, the approval or recommendation by such
Board of Directors or such committee of the Merger, this Agreement or the
issuance of shares of Acquiror Common Stock in the Merger, (ii) approve or
recommend, or propose publicly to approve or recommend, any Takeover Proposal
or (iii) cause Target or Acquiror, as the case may be, to enter into any
Takeover Proposal. Notwithstanding the foregoing, in the event that the Board
of Directors of Target or Acquiror, as the case may be, has fully complied with
this Section 5.1 and determines that a Superior Proposal exists, the Board of
Directors of Target or Acquiror, as the case may be, to the extent required by
the fiduciary obligations thereof, as determined in the good faith judgment of
such Board of Directors based on the advice of outside counsel, may withdraw or
modify its approval or recommendation of the Merger and this Agreement;
provided, however, that nothing contained herein (including any such withdrawal
or modification of such approval or recommendation) shall release or otherwise
affect (A) Target's obligation to call and hold the Target Stockholders'
Meeting and submit the Merger and this Agreement to the stockholders of Target
for their approval or (B) Acquiror's obligation to call and hold the Acquiror's
Stockholders' Meeting and submit the Merger and this Agreement to the
stockholders of Acquiror for their approval.

   5.2 Proxy Statement/Prospectus; Registration Statement. As promptly as
practicable after the execution of this Agreement, Target and Acquiror shall
prepare a Registration Statement on Form S-4 (containing a prospectus and proxy
materials relating to the approval of the Merger and the transactions
contemplated hereby by the stockholders of Target and Acquiror) and, as
promptly as practicable, Acquiror shall file with the SEC a Registration
Statement on Form S-4 (or such other or successor form as shall be
appropriate), which complies in form with applicable SEC requirements and shall
use reasonable best efforts to cause the Registration Statement to become and
remain effective as soon thereafter as practicable. The Proxy Statement shall
include the recommendation of the Board of Directors of Acquiror and Target in
favor of the Merger;

   5.3 Access to Information.

the business, properties and personnel of Target as Acquiror may reasonably
request. Target agrees to provide to Acquiror and its accountants, counsel and
other representatives, subject to existing confidentiality agreements with
third parties, copies of internal financial statements promptly upon request.

   (b) Subject to compliance with applicable law, from the date hereof until
the Effective Time, each of Acquiror and Target shall confer on a regular and
frequent basis with one or more representatives of the other party to report
operational matters of materiality and the general status of ongoing
operations.

   (c) No information or knowledge obtained in any investigation pursuant to
this Section 5.3 shall affect or be deemed to modify any representation or
warranty contained herein or the conditions to the obligations of the parties
to consummate the Merger.

   5.4 Confidentiality. The parties acknowledge that Acquiror and Target have
previously executed a non-disclosure agreement dated December 18, 2000 (the

Acquiror and Target shall consult with each other before issuing any press
release or otherwise making any public statement or making any other public (or
non-confidential) disclosure (whether or not in response to an inquiry)
regarding the terms of this Agreement and the transactions contemplated hereby,
and neither shall issue any such press release or make any such statement or
disclosure without the prior approval of the other (which approval shall not be
unreasonably withheld or delayed), except as may be required by Acquiror to

and shall use all commercially reasonable efforts to obtain all necessary
consents, waivers and approvals under any of Target's material contracts in
connection with the Merger for the assignment thereof or otherwise.

   5.7 Update Disclosure; Breaches. From and after the date of this Agreement
until the Effective Time, each party hereto shall promptly notify the other
party, by written update to its Disclosure Schedule, of (i) the occurrence or
non-occurrence of any event which would be likely to cause any condition to the
obligations of any party to effect the Merger and the other transactions
contemplated by this Agreement not to be satisfied, or (ii) the failure of
Target or Acquiror, as the case may be, to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it pursuant to this
Agreement which would be likely to result in any condition to the obligations
of any party to effect the Merger and the other transactions contemplated by
this Agreement not to be satisfied. The delivery of any notice pursuant to this
Section 5.7 shall not cure any breach of any representation or warranty
requiring disclosure of such matter prior to the date of this Agreement or
otherwise limit or affect the remedies available hereunder to the party
receiving such notice.

   5.8 Affiliates Agreements. Upon the execution of this Agreement, Target will
provide Acquiror with a list of those persons who are, in Target's respective
reasonable judgment, "affiliates" of Target, respectively, within the meaning
of Rule 145 under the Act ("Rule 145"). Each such person who is an "affiliate"
of Target within the meaning of Rule 145 is referred to herein as an
"Affiliate." Target shall provide Acquiror such information and documents as
Acquiror shall reasonably request for purposes of reviewing such list and shall
notify Acquiror in writing regarding any change in the identity of its
Affiliates prior to the Closing Date. Upon the execution of this Agreement,
Target shall deliver or cause to be delivered to Acquiror from each of the
Affiliates of Target, an executed Affiliates Agreement, in the form attached
hereto as Exhibit C. Acquiror shall be entitled to place appropriate legends on
the certificates evidencing any Acquiror Common Stock to be received by
Affiliates of Target pursuant to the terms of this Agreement, and to issue
appropriate stop transfer instructions to the transfer agent for the Acquiror
Common Stock, consistent with the terms of the Affiliates Agreement. The
Acquiror shall make and keep public information available, as those terms are
understood and defined in Rule 144 under the Act, for a period of three (3)
years after the Closing Date.

   5.9 Lock-Up Agreements. Prior to the Effective Time, holders of at least 80%
of the Target Capital Stock, the Target Options and the Target Warrants, on a
fully diluted basis, and each officer and director of Target shall execute and
deliver a lock-up agreement to Acquiror in the form attached hereto as Exhibit
F (the "Lock-Up Agreements").

   5.10 Legal Requirements. Each of Acquiror and Target will, and Acquiror will
cause its subsidiaries to, take all reasonable actions necessary to comply
promptly with all legal requirements which may be imposed on them with respect
to the consummation of the transactions contemplated by this Agreement and will
promptly cooperate with and furnish information to any party hereto necessary
in connection with any such requirements imposed upon such other party in
connection with the consummation of the transactions contemplated by this
Agreement and will take all reasonable actions necessary to obtain (and will
cooperate with the other parties hereto in obtaining) any consent, approval,
order or authorization of, or any registration, declaration or filing with, any
federal, state or local governmental authority or other person, required to be
obtained or made in connection with the taking of any action contemplated by
this Agreement.

   5.11 Tax-Deferred Reorganization. Neither Target, Acquiror nor Merger Sub
will, either before or after consummation of the Merger, take any action that,
to the knowledge of such party, would cause the Merger to fail to constitute a
"reorganization" within the meaning of Code Section 368. No party to this
Agreement shall take a position on any return, report or filing inconsistent
with this treatment.

   5.12 Blue Sky Laws. Acquiror shall take such steps as may be necessary to
comply with the securities and blue sky laws of all jurisdictions which are
applicable to the issuance of the Acquiror Common Stock in

                                      A-22
<PAGE>

connection with the Merger. Target shall use its best efforts to assist
Acquiror as may be necessary to comply with the securities and blue sky laws of
all jurisdictions which are applicable in connection with the issuance of
Acquiror Common Stock in connection with the Merger.

   5.13 Stock Options and Warrants.

   (a) At the Effective Time, the Target Stock Option Plan and each outstanding
Target Option and each outstanding Target Warrant, whether vested or unvested,
shall, by virtue of the Merger and without any further consideration on the
part of any holder thereof, be assumed by Acquiror and be converted into an
option (or warrant, as the case may be) to purchase shares of Acquiror Common
Stock as set forth below. Target has delivered to Acquiror a schedule (the
"Option Schedule") which sets forth a true and complete list as of the date
hereof of all Target Warrants and Target Options, including the number of
shares of Target Capital Stock subject to each such option or warrant, the
exercise or vesting schedule, the exercise price per share and the term of each
such option or warrant. On the Closing Date, Target shall deliver to Acquiror
an updated Option Schedule current as of such date. Each such Target Option or
Target Warrant so assumed by Acquiror under this Agreement shall continue to
have, and be subject to, the same terms and conditions set forth in the Target
Stock Option Plan or the Target Warrant, as the case may be, immediately prior
to the Effective Time, except that (i) such option or warrant shall be
exercisable for that number of whole shares of Acquiror Common Stock equal to
the product of the number of shares of Target Common Stock that were issuable
upon exercise of such option or warrant immediately prior to the Effective Time
multiplied by the exchange ratio as set forth on the Option Schedule and
rounded to the nearest whole number of shares of Acquiror Common Stock, and
(ii) the per share exercise price for the shares of Acquiror Common Stock
issuable upon exercise of such assumed option or warrant shall be equal to the
quotient determined by dividing the exercise price per share of Target Common
Stock at which such option or warrant was exercisable immediately prior to the
Effective Time by the exchange ratio as set forth on the Option Schedule,
rounded to the nearest whole cent. The exchange ratio set forth on the Option
Schedule shall be adjusted, as of the Effective Time, if necessary to reflect
any exercise, cancellation or expiration of any Target Options or Target
Warrants prior to the Effective Time such that the total number of Acquiror
Common Shares to be reserved for issuance upon the exercise of all Target
Options and all Target Warrants assumed by Acquiror hereunder is equal to
1,583,200. In no event, however, shall the number of Acquiror Common Shares
reserved for issuance upon the exercise of Target Options and Target Warrants
exceed 1,583,200 shares of Acquiror Common Stock.

   (b) Acquiror shall take all corporate action necessary to reserve and make
available for issuance a sufficient number of shares of Acquiror Common Stock
for delivery upon the exercise of the Target Options and Target Warrants
assumed in accordance with this Section 5.13. At or prior to the Effective
Time, Acquiror shall file a registration statement on Form S-8 (or any
successor or other appropriate forms) with respect to the shares of Acquiror
Common Stock subject to such Target Options and Target Warrants and shall use
its best efforts to maintain the effectiveness of such registration statement
or registration statements (and maintain the current status of the prospectus
or prospectuses contained therein) for so long as such Target Options and
Target Warrants remain outstanding.

   5.14 Listing of Additional Shares. Prior to issuance, Acquiror shall file
with NASDAQ a Notification Form for Listing of Additional Shares covering the
shares of Acquiror Common Stock issuable upon conversion of the Target Capital
Stock in the Merger, upon exercise of the Target Options assumed by Acquiror
and upon exercise of the Target Warrants assumed by Acquiror.

   5.15 Additional Agreements; Reasonable Efforts. Each of the parties agrees
to use all reasonable efforts to take, or cause to be taken, all action and to
do, or cause to be done, all things necessary, proper or advisable under
applicable laws and regulations to consummate and make effective the
transactions contemplated by this Agreement, subject to the appropriate vote of
stockholders of Target and Acquiror, including cooperating fully with the other
party, including by provision of information. In case at any time after the
Effective Time any further action is necessary or desirable to carry out the
purposes of this Agreement or to vest the Surviving Corporation with full title
to all properties, assets, rights, approvals, immunities and franchises of
Target, the proper officers and directors of each party to this Agreement shall
take all such necessary action.

                                      A-23

   5.16 Employee Benefits. Acquiror shall take such reasonable actions, to the
extent permitted by Acquiror's benefit programs, as are necessary to allow
eligible employees of Target to participate in the benefit programs of
Acquiror, or alternative benefit programs in the aggregate substantially
comparable to those applicable to employees of Acquiror on similar terms, as
soon as practicable after the Effective Time of the Merger. For purposes of
satisfying the terms and conditions of such programs, to the extent permitted
by Acquiror's benefit programs, Acquiror shall use reasonable efforts to give
full credit for eligibility, or vesting for each participant's period of
service with Target.

   5.17 Parachute Payments. Target shall use its best efforts to have any
agreements or arrangements that may result in the payment of any amount that
would not be deductible by reason of Section 280G of the Code approved by such
percentage of Target's outstanding voting securities as is required by the
terms of Section 280G(b)(5)(B) of the Code and the proposed Treasury
Regulations thereunder, including, without limitation, Q-7 of Section 1.280G-1
of such proposed regulations.

   5.18 Necessary Actions. Acquiror and Target shall execute and deliver at the
Closing all agreements and documents contemplated by this Agreement to be
executed and delivered by them at the Closing.

   5.19 Target Director and Officer Indemnification.

   (a) After the Effective Time, Acquiror will, and will cause the Surviving
Corporation to (i) indemnify, defend and hold harmless the present and former
officers, directors, employees and agents of Target (the "Indemnified Parties")
in respect of acts or omissions occurring on or prior to the Effective Time to
the extent provided under applicable law or under Target's Certificate of
Incorporation and Bylaws, in each case as in effect on the date hereof, and
(ii) advance expenses as incurred by such officers, directors, employees and
agents of Target to the fullest extent permitted under applicable law or under
Target's Certificate of Incorporation and Bylaws, in each case as in effect on
the date hereof, provided that such indemnification and advancement of expenses
shall be subject to any limitation imposed from time to time under applicable
law.

   (b) The provisions of this Section 5.19 are intended to be for the benefit
of, and shall be enforceable by, each of the Indemnified Parties, their heirs
and personal representatives.

  seeking any of the foregoing be pending; nor shall there be any action
  taken, or any statute, rule, regulation or order enacted, entered, enforced

7.2 shall remain in full force and effect and survive any termination of this
Agreement.

   7.3 Termination Fees.

   (a) In the event that this Agreement is terminated due to the fact Acquiror

shall not have received the requisite stockholder and/or board of director
votes required to approve the transactions contemplated by this Agreement, then
Target shall pay Acquiror a fee in the amount of one million dollars
($1,000,000). In the event the Board of Directors of Target has fully complied
with Section 5.1 and determines that a Superior Proposal exists, the Board of

including the filing of any lawsuit or legal action, together with interest on
the amount of any unpaid fee at the so-called composite "prime rate" as quoted

                               GENERAL PROVISIONS

   8.1 Survival of Representations, Warranties and Covenants. Notwithstanding
any investigation conducted before or after the Closing Date, and
notwithstanding any actual or implied knowledge or notice of any facts or
circumstances which Acquiror or Target may have as a result of such
investigation or otherwise, Acquiror and Target will be entitled to rely upon
the other party's representations, warranties and covenants set forth in this
Agreement. The representations and warranties of Target and Acquiror will
terminate upon the Closing; provided however, that (i) the obligations of each
party with respect to any intentional or fraudulent breaches of its
representations and warranties will survive the Closing and continue in full
force and effect until the date twelve (12) months following the Closing Date
(the "Survival Period"), at which time, the representations and warranties of
each party set forth in this Agreement will terminate and (ii) the
representation made by Acquiror in the last sentence of Section 3.2 shall
survive indefinitely. The affirmative covenants and agreements of the parties
set forth in this Agreement shall survive until fulfilled and the negative
covenants and agreements of the parties set forth in this Agreement shall
survive until the statute of limitations with respect to the subject matter of
such covenant or agreements has run.

   8.2 Maximum Liability and Remedies. Nothing herein shall limit any potential
remedies or liabilities of a party hereto with respect to any claim made
pursuant to Section 8.1 hereof during the Survival Period; provided that (a)
the liability of each Target stockholder hereunder shall be limited to ten
percent (10%) of the consideration received by such stockholder in the Merger
and the liability of each Target stockholder shall be several (meaning pro rata
in proportion to the consideration received by such stockholder) and not joint,
and (b) the liability of Acquiror hereunder to the Target stockholders shall be
limited to the consideration received by such stockholder in the Merger.
Nothing in this Agreement shall limit the liability of any Target stockholder
in connection with any breach by such stockholder of the Affiliates Agreement
and/or the Target Voting Agreement.

   8.3 Notices. All notices and other communications hereunder shall be in
writing and shall be deemed given if delivered personally or by commercial

   8.4 Interpretation. When a reference is made in this Agreement to Exhibits,
such reference shall be to an Exhibit to this Agreement unless otherwise
indicated. The words "include," "includes" and "including" when used herein
shall be deemed in each case to be followed by the words "without limitation."
In this Agreement, any reference to any event, change, condition or effect
being "material" with respect to any entity or group of entities means any
material event, change, condition or effect related to the condition (financial
or otherwise), properties, assets (including intangible assets), liabilities,
business, operations or results of operations of such entity or group of
entities. In this Agreement, any reference to a "Material Adverse Effect" with
respect to any entity or group of entities means any event, change or effect
that is materially adverse to the condition (financial or otherwise),
properties, assets (including intangible assets), liabilities, business,
operations or results of operations of such entity, taken as a whole, except
changes caused by the announcement of, or the response or reaction of
customers, vendors, licensors, investors or employees of, Target or Acquiror to
this Agreement and the transactions contemplated hereby, changes, circumstances
or conditions affecting Target's or Acquiror's industry in general or changes
in general economic, regulatory or political conditions. In this Agreement, any
reference to a party's "knowledge" means such party's actual knowledge after
due and diligent inquiry of Gordon Mayer, Toni Sikes and Lori Wetzel for Target
and Kenneth Kurtzman, Brian Bergeron and Gary Paranzino for Acquiror. The
phrase "made available" in this Agreement shall mean that the information
referred to has been made available if requested by the party to whom such
information is to be made available. The words "tax" or "taxable" shall mean
any federal, state, local, municipal or foreign net income, gross income, gross
receipts, windfall profit, severance, property, production, sales, use,
license, excise, franchise, employment, payroll, withholding, alternative or
add-on minimum, ad valorem, value-added, transfer, stamp, or environmental tax,
or any other tax, custom, duty, tariff levy, import, governmental fee or other
like assessment or charge of any kind whatsoever, together with any interest or
penalty, addition to tax or additional amount imposed by any governmental or
regulatory authority, domestic and foreign. The phrases "the date of this
Agreement", "the date hereof", and terms of similar import, unless the context
otherwise requires, shall be deemed to refer to the Agreement Date. The table
of contents and headings contained in this Agreement are for reference purposes
only and shall not affect in any way the meaning or interpretation of this
Agreement.

   8.5 Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each
of the parties and delivered to the other parties, it being understood that all
parties need not sign the same counterpart.

   8.6 Entire Agreement; No Third Party Beneficiaries. This Agreement, the
Target Transaction Documents, the Acquiror Transaction Documents, and the other
documents and instruments and other agreements specifically referred to herein
or delivered pursuant hereto, including the Exhibits, the Schedules, including
the Target Disclosure Schedule and the Acquiror Disclosure Schedule (a)
constitute the entire agreement among the

                                      A-30
<PAGE>

parties with respect to the subject matter hereof and supersede all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter hereof, except for the Confidentiality Agreement,
which shall continue in full force and effect, and shall survive any
termination of this Agreement or the Closing, in accordance with its terms and
(b) are not intended to confer upon any other person any rights or remedies
hereunder, except for the rights of the Target stockholders to receive the
consideration set forth in Article I of this Agreement and except for the
rights of the holders of the Target Options and the Target Warrants to receive
the options or warrants, as appropriate, pursuant to Section 5.13 of this
Agreement.

   8.7 Severability. In the event that any provision of this Agreement, or the
application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as
reasonably to effect the intent of the parties hereto. The parties further
agree to replace such void or unenforceable provision of this Agreement with a
valid and enforceable provision that will achieve, to the extent possible, the
economic, business and other purposes of such void or unenforceable provision.

   8.8 Remedies Cumulative. Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity
upon such party, and the exercise by a party of any one remedy will not
preclude the exercise of any other remedy.

   8.9 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware without regard to applicable
principles of conflicts of law. Each of the parties hereto irrevocably consents
to the exclusive jurisdiction of any court located within the State of
Delaware, in connection with any matter based upon or arising out of this
Agreement or the matters contemplated herein, agrees that process may be served
upon them in any manner authorized by the laws of the State of Delaware for
such persons and waives and covenants not to assert or plead any objection
which they might otherwise have to such jurisdiction and such process.

   8.10 Assignment. Neither this Agreement nor any of the rights, interests or
obligations hereunder shall be assigned by any of the parties hereto (whether
by operation of law or otherwise) without the prior written consent of the
other parties. Subject to the preceding sentence, this Agreement will be
binding upon, inure to the benefit of and be enforceable by the parties and
their respective successors and permitted assigns.

   8.11 Rules of Construction. The parties hereto agree that they have been
represented by counsel during the negotiation, preparation and execution of
this Agreement and, therefore, waive the application of any law, regulation,
holding or rule of construction providing that ambiguities in an agreement or
other document will be construed against the party drafting such agreement or
document.
