                               SUMMARY TERM SHEET

   Trilogy Software, Inc., is offering to purchase any and all of the
outstanding shares of Class A common stock of pcOrder.com, Inc. for $6.375 net
cash per share. The following are some of the questions that you, as a
stockholder of pcOrder, may have and answers to those questions. We urge you to
carefully read the remainder of this Offer to Purchase and the accompanying
Letter of Transmittal because the information in this summary is not complete.
Additional important information is contained in the remainder of this Offer to
Purchase and the accompanying Letter of Transmittal.

WHO IS OFFERING TO BUY MY SECURITIES?

   Our name is Trilogy Software, Inc. We are a privately-owned Delaware
corporation. We are offering to purchase any and all of the outstanding shares
of Class A common stock of pcOrder pursuant to a Merger Agreement among us,
pcOrder and POI Acquisition Corp., Inc., our newly formed, wholly-owned
subsidiary.

   We provide sales, marketing and business-to-business e-commerce
applications. Our software solutions are designed to integrate each function in
a company's sales and marketing operation, including pricing management,
product management, sales, commissions, promotions, contract management and
channel management. In addition, our software solutions are designed to enable
companies to engage in e-commerce, as well as improve channel management
processes.

   We formed pcOrder in 1994 and reduced our ownership in it from 100% in two
public offerings in 1999. As of the date of this Offer to Purchase, we
beneficially own 10,316,620 shares of pcOrder's Class B common stock. These
shares are immediately convertible into 10,316,620 shares of Class A common
stock of pcOrder. Our holdings of Class B common stock represent approximately
62% of the outstanding Class A and Class B common stock of pcOrder and
approximately 93% of pcOrder's voting power. Our majority stockholder and chief
executive officer is one of five members of the Board of Directors of pcOrder
and the pcOrder Board includes another director who is a partner in a venture
capital firm that is one of our investors.

   See the "Introduction" to this Offer to Purchase and "The Tender Offer--
Section 8. Certain Information Concerning Trilogy and Sub."

WHAT ARE THE CLASSES AND AMOUNTS OF SECURITIES SOUGHT IN THE OFFER?

   We are seeking to purchase any and all of pcOrder's outstanding Class A
common stock.

   See the "Introduction" to this Offer to Purchase and "The Tender Offer--
Section 1. Terms of the Offer; Expiration Date."

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

   We are offering to pay $6.375 per share, net to you in cash. If you are the
record owner of your shares and you tender your shares to us in the offer, you
will not have to pay brokerage fees or similar expenses. If you own your shares
through a broker or other nominee, and your broker tenders your shares on your
behalf, your broker or nominee may charge you a fee for doing so. You should
consult your broker or nominee to determine whether any charges will apply.

   See the "Introduction" to this Offer to Purchase and "The Tender Offer--
Section 3. Procedures for Tendering Shares."

DO YOU HAVE THE FINANCIAL RESOURCES TO MAKE PAYMENT?

   We have sufficient funds from our own resources to purchase all shares of
pcOrder Class A common stock at $6.375 per share. We anticipate that all of the
funds will be obtained from our existing resources, including internally
generated funds. We do not need to use pcOrder's cash or assets to finance the
offer or the merger. The offer is not conditioned upon any financing
arrangements.

                                       1
<PAGE>

   See "The Tender Offer--Section 9. Source and Amount of Funds."

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

   We do not think our financial condition is relevant to your decision whether
to tender in the offer because the form of payment consists solely of cash, and
all of our funding will come from existing resources, including internally
generated funds. Additionally, the offer is not subject to any financing
condition.

   See "The Tender Offer--Section 9. Source and Amount of Funds."

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

   You will have until 12:00 midnight, New York City time, on Wednesday,
December 6, 2000, to tender your shares in the offer, unless the offer is
extended. Further, if you cannot deliver everything that is required in order
to make a valid tender by that time, you may be able to use a guaranteed
delivery procedure, which is described later in this Offer to Purchase.

   See "The Tender Offer--Section 1. Terms of the Offer; Expiration Date" and
"--Section 3. Procedures for Tendering Shares."

CAN THE OFFER BE EXTENDED AND UNDER WHAT CIRCUMSTANCES?

   Subject to the terms of the merger agreement, we can extend the offer. If we
have not purchased any shares under the offer by January 31, 2001, either we or
pcOrder can terminate the merger agreement.

   See "The Tender Offer--Section 1. Terms of the Offer; Expiration Date."

HOW WILL I BE NOTIFIED IF THE OFFER IS EXTENDED?

   If we extend the offer, we will inform American Stock Transfer & Trust
Company, the depositary for the offer, of that fact, and we will make a public
announcement of the extension, not later than 9:00 a.m., New York City time, on
the next business day after the day on which the offer was scheduled to expire.

   See "The Tender Offer--Section 1. Terms of the Offer; Expiration Date."

ARE THERE CONDITIONS TO THE OFFER?

   Our offer is subject to certain conditions. To the extent permitted by law,
we can waive all of the conditions to the offer in our sole discretion. The
offer is not conditioned on any minimum number of shares being tendered.

   See "The Tender Offer--Section 1. Terms of the Offer; Expiration Date" and
"--Section 13. Certain Conditions to the Offer."

HOW DO I TENDER MY SHARES?

   To tender your shares, you must deliver the certificates evidencing your
shares, together with a completed Letter of Transmittal, to American Stock
Transfer & Trust Company, the depositary for the offer, not later than the time
the offer expires.

   If your shares are held in street name (that is, through a broker, dealer or
other nominee), the shares can be tendered by your nominee through The
Depository Trust Company. If you cannot get a required document to

                                       2
<PAGE>

the depositary by the expiration of the offer, you may gain some extra time to
do so by having a broker, bank or other fiduciary who is an "eligible
institution" (as defined in Instruction 1 to the Letter of Transmittal)
guarantee that the missing items will be received by the depositary within
three Nasdaq National Market System trading days. However, the depositary must
receive the missing items within that three-day trading period.

   See "The Tender Offer--Section 3. Procedures for Tendering Shares."

UNTIL WHAT TIME CAN I WITHDRAW PREVIOUSLY TENDERED SHARES?

   You can withdraw previously tendered shares at any time until the offer has
expired and, if we have not agreed to accept your shares for payment by January
4, 2001, you can withdraw them at any time after such time until we do accept
your shares for payment. This right to withdraw will not apply to any
subsequent offering period.

   See "The Tender Offer--Section 1. Terms of the Offer; Expiration Date" and
"--Section 4. Withdrawal Rights."

HOW DO I WITHDRAW PREVIOUSLY TENDERED SHARES?

   To withdraw shares, you must deliver a written notice of withdrawal, or a
facsimile of one, with the required information to the depositary while you
still have the right to withdraw the shares.

   See "The Tender Offer--Section 4. Withdrawal Rights."

WHAT DOES THE BOARD OF DIRECTORS OF PCORDER THINK OF THE OFFER?

   The Board of Directors of pcOrder, based upon a unanimous recommendation of
a Special Committee made up of independent directors:

  .  has determined that the offer and the merger are fair to and in the best
     interests of pcOrder stockholders (other than us and our affiliates);

  .  has approved the merger agreement, the offer and the merger; and

  .  recommends that you accept the offer and tender your shares to us.

   See the "Introduction" to this Offer to Purchase and "Special Factors--
Recommendation of the pcOrder Special Committee and the pcOrder Board; Fairness
of the Offer and the Merger."

WILL THE TENDER OFFER BE FOLLOWED BY A MERGER IF NOT ALL THE PUBLICLY-TRADED
SHARES OF PCORDER ARE TENDERED IN THE OFFER?

   Yes. Following the offer, POI Acquisition Corp. will be merged with and into
pcOrder. If the merger takes place, pcOrder will become a privately owned
company, and all of the remaining stockholders of pcOrder (other than us, or
any of our affiliates excluding pcOrder, and other than stockholders properly
exercising appraisal rights) will receive $6.375 per share in cash (or any
other higher price per share that is paid in the offer).

   See the "Introduction" to this Offer to Purchase.

FOLLOWING THE OFFER, WILL PCORDER CONTINUE AS A PUBLIC COMPANY?

   The tender offer is one step in our complete acquisition of pcOrder, the
second step being the merger. Depending on the number of shares we purchase in
the offer, it is possible that even if the merger is not

                                       3
<PAGE>

completed there may be so few remaining stockholders and publicly held shares
that the shares will no longer be eligible to be traded on the Nasdaq National
Market System or other securities markets. In that event, there may not be a
public trading market for the shares, and pcOrder may cease making filings
with the Securities and Exchange Commission or may otherwise cease being
required to comply with the rules of the Securities and Exchange Commission
governing publicly-held companies.

   Even if these consequences do not result from the offer, if the merger is
completed we will own 100% of the outstanding equity of pcOrder. However, the
length of time between the completion of the offer and the closing of the
merger will depend on whether we own 90% of the publicly-held shares after the
offer is completed. If we do, we can, and will, complete the merger right
away. If we do not, the merger will have to be voted on by stockholders, and
this could take a few weeks during which pcOrder may still be a public company
(again, depending on how many shares we purchase in the offer).

   If we complete the offer but one of the conditions to the merger is not
satisfied and the merger does not happen, then it is possible pcOrder would
have sufficent stockholders and publicly-held shares to remain public.

   See "Special Factors--The Merger Agreement--Conditions to the Merger" and
"The Tender Offer--Section 11. Certain Effects of the Offer on the Market for
the Shares."

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

   If the merger takes place, stockholders not tendering in the offer and not
properly exercising appraisal rights will receive the same amount of cash per
share that they would have received had they tendered their shares in the
offer. Therefore, if the merger takes place, the only difference to you
between tendering your shares and not tendering your shares is that you will
be paid earlier if you tender your shares in the offer.

   However, if for some reason the merger does not take place, the number of
stockholders and the number of publicly-held shares that are still in the
hands of the public may still be so small that there will no longer be an
active public trading market (or, possibly, any trading market) for the
shares. Also, as described above, pcOrder may cease making filings with the
Securities and Exchange Commission or may otherwise cease being required to
comply with the rules of the Securities and Exchange Commission relating to
publicly-held companies.

   See the "Introduction" to this Offer to Purchase and "The Tender Offer--
Section 11. Certain Effects of the Offer on the Market for the Shares."

ARE APPRAISAL RIGHTS AVAILABLE?

   There are no appraisal rights in connection with the offer. However, if the
merger takes place, stockholders who have not sold their shares in the offer,
have not voted for the merger, and have complied with other requirements of
Delaware law will have appraisal rights under Delaware law.

   See "Special Factors--Dissenters' Rights."

WHAT IS THE MARKET VALUE OF MY SHARES AS OF A RECENT DATE?

   On October 24, 2000, the last trading day before we announced the
companies' agreement on the offer and the merger, the last sale price of the
shares reported on the Nasdaq National Market System was $3.4375 per share. On
November 3, 2000, the last full trading day prior to the commencement of the
offer, the last sale price of the shares reported on the Nasdaq National
Market System was $6.125 per share.

   We encourage you to obtain a recent quotation for the shares in deciding
whether to tender your shares.

   See "The Tender Offer--Section 6. Price Range of Shares."

                                       4
<PAGE>

WHAT ARE THE FEDERAL INCOME TAX CONSEQUENCES OF TENDERING SHARES?

   The receipt of cash for shares pursuant to the offer or the merger will be a
taxable transaction for United States federal income tax purposes and possibly
for state, local and foreign income tax purposes as well.

   In general, a stockholder who sells shares in the offer or receives cash in
exchange for shares in the merger will recognize gain or loss for United States
federal income tax purposes equal to the difference, if any, between the amount
of cash received and the stockholder's adjusted tax basis in the shares sold in
the offer or exchanged for cash in the merger. If the shares exchanged
constitute capital assets in the hands of the stockholder, such gain or loss
will be capital gain or loss. In general, capital gains recognized by an
individual will be subject to a maximum United States federal income tax rate
of 20% if the shares were held for more than one year, and if held for one year
or less, they will be subject to tax at ordinary income tax rates.

   WE ENCOURAGE YOU TO CONSULT YOUR OWN TAX ADVISOR REGARDING THE TAX EFFECTS
OF THE OFFER FOR YOU. BECAUSE OF YOUR INDIVIDUAL CIRCUMSTANCES, THE OFFER MAY
HAVE DIFFERENT TAX CONSEQUENCES FOR YOU THAN FOR STOCKHOLDERS GENERALLY.

   See "The Tender Offer--Section 5. Certain U.S. Federal Income Tax
Consequences."

WHO MAY I TALK TO IF I HAVE QUESTIONS ABOUT THE OFFER?

   MacKenzie Partners, Inc. is acting as the information agent for our offer
and SG Cowen Securities Corporation is acting as the dealer manager for our
offer. See the back cover of this Offer to Purchase. You may call MacKenzie
Partners, Inc. at (212) 929-5500 (call collect) or (800) 322-2885 (call toll

To the Holders of Class A Common Stock of
pcOrder.com, Inc.:

                                  INTRODUCTION

   Trilogy Software, Inc., a Delaware corporation ("Trilogy"), hereby offers to
purchase any and all of the outstanding shares of Class A common stock, par
value $0.01 per share (the "Shares" or the "Class A Common Stock"), of
pcOrder.com, Inc., a Delaware corporation ("pcOrder"), at $6.375 per Share, net
to the tendering stockholder in cash (the "Offer Price"), upon the terms and
subject to the conditions set forth in this Offer to Purchase and in the
related Letter of Transmittal (which together, as they may be amended and
supplemented from time to time, constitute the "Offer"). As of the date hereof,
Trilogy beneficially owned 10,316,620 shares of pcOrder's Class B common stock,
par value $0.01 per share (the "Class B Common Stock"), which are immediately
convertible at the option of Trilogy into 10,316,620 Shares and represent
approximately 62% of pcOrder's outstanding combined Class A Common Stock and
Class B Common Stock and approximately 93% of pcOrder's voting power. Tendering
stockholders will not be obligated to pay brokerage fees or commissions or,
except as set forth in the Letter of Transmittal, transfer taxes on the
purchase of Shares by Trilogy pursuant to the Offer. Trilogy will pay all
charges and expenses of SG Cowen Securities Corporation as the Dealer Manager
(the "Dealer Manager"), MacKenzie Partners, Inc., as the Information Agent (the
"Information Agent"), and American Stock Transfer & Trust Company, as the
Depositary (the "Depositary"), incurred in connection with the Offer.

   The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of October 25, 2000 (the "Merger Agreement"), by and among Trilogy, POI
Acquisition Corp., Inc., a Delaware corporation and wholly-owned subsidiary of
Trilogy formed solely to effect the transactions contemplated by the Merger
Agreement ("Sub"), and pcOrder. The Merger Agreement provides, among other
things, for the making of the Offer by Trilogy, and further provides that, as
soon as practicable after the completion of the Offer and the satisfaction or
waiver of the conditions set forth in the Merger Agreement, Sub will be merged
with and into pcOrder (the "Merger") in accordance with the applicable
provisions of the Delaware General Corporation Law (the "DGCL"). Following the
Merger, pcOrder shall be the surviving corporation (the "Surviving
Corporation"), and the separate existence of Sub shall cease. At the effective
time of the Merger (the "Effective Time"), (i) each issued and outstanding
Share (other than Shares held in the treasury of pcOrder or by Trilogy and Sub
and Shares held by stockholders who have properly exercised dissenters' rights
(the "Dissenting Shares") under the DGCL ("Dissenters' Rights")) will be
converted into and represent the right to receive the Offer Price, in cash,
without interest (the "Merger Consideration"), and (ii) each share of common
stock, par value $0.01 per share, of Sub (the "Sub Common Stock"), then issued
and outstanding will be converted into and become one share of common stock of
the Surviving Corporation. Dissenters' Rights are available only in connection
with the Merger and not in connection with the Offer. See "Special Factors--The
Merger Agreement" for a description of the Merger and the Merger Agreement.

   If Trilogy owns 90% or more of the outstanding Shares as a result of the
Offer and continues to hold at least 90% of the outstanding Class B Common
Stock, then Trilogy intends to transfer all of the Shares purchased by Trilogy
in the Offer and its Class B Common Stock to Sub and cause Sub to effect the
Merger as a "short-form" merger under the DGCL, without a vote of the
stockholders of pcOrder (a "Short-Form Merger"). If following the purchase of
Shares pursuant to the Offer, Trilogy owns in the aggregate less than 90% of
the Shares outstanding, Trilogy has agreed to convert such number of shares of
Class B Common Stock into Class A Common Stock to the extent that, after giving
effect to such conversion, Trilogy would own in the aggregate the number of
Shares necessary to effect a Short-Form Merger. If a vote of the stockholders
of pcOrder is necessary to effect the Merger because Trilogy does not own 90%
of the outstanding Shares, Trilogy has agreed in the Merger Agreement to vote
or cause to be voted all shares of pcOrder's capital stock owned by it and its

                                SPECIAL FACTORS

BACKGROUND OF THE OFFER AND THE MERGER

   In July 1993, pcOrder commenced operations as a separate business unit of
Trilogy.

   In July 1994, pcOrder was incorporated as a separate corporation wholly-
owned by Trilogy.

   In June 1996, Trilogy transferred the assets of its pcOrder.com business
unit to pcOrder in exchange for equity in pcOrder. As part of that transaction,
Trilogy agreed not to compete with pcOrder for a period of three years.

   From June 1996 through January 1999, Trilogy and pcOrder put into place
several agreements to govern their relationship, including a management
services agreement, a tax allocation agreement and a technology, services and
license agreement. See "Special Factors--Related Party Transactions" for a
description of these agreements.

   In January 1999, pcOrder amended its certificate of incorporation to provide
for two classes of stock, Class A Common Stock, which entitles a holder to one
vote per share, and Class B Common Stock, which entitles a holder to eight
votes per share. The Class B Common Stock is immediately convertible into
shares of Class A Common Stock on a one-for-one basis so long as it is held by
Trilogy. Trilogy holds all of the shares of Class B Common Stock.

   In February 1999, pcOrder completed an initial public offering of 2,530,000
Shares at $21.00 per Share. After this offering, Trilogy owned approximately
82% of the outstanding shares of pcOrder's capital stock and approximately 97%
of pcOrder's aggregate voting power by virtue of the eight votes per share
associated with the Class B Common Stock. As of the time of the initial public
offering, pcOrder consisted of three principal distinct and interrelated
divisions: (a) the enterprise software division, which provided sales,
marketing, distribution and e-commerce software applications; (b) the content
division, which provided detailed technical specifications, and product pricing
and availability information; and (c) the community business, which consisted
of online services for resellers, including sales quoting tools and e-commerce
storefronts. Together, these three divisions were designed to enable the
computer industry's suppliers, resellers and end users to buy and sell products
online.

   On June 1, 1999, the three-year noncompetition agreement between pcOrder and
Trilogy, which had been put in place when Trilogy transferred the assets of its
pcOrder.com division to pcOrder, expired. Since that date, there have been no
contractual restrictions limiting Trilogy's ability to compete with pcOrder.

   Historically, pcOrder had sold its content in conjunction with its software
applications. In April 1999, pcOrder publicly launched ContentSource, a
subscription-based service that allows customers to subscribe solely to its
content without licensing software. The service is primarily targeted towards
Internet retailers, corporate resellers, distributors and Internet shopping
services. Around that time, GDT, S.A. a Swiss company, began marketing computer
product content. In July 1999, CNET Networks, Inc. ("CNET") acquired GDT and
became a competitor of pcOrder's ContentSource.

   In December 1999, pcOrder completed a second public offering of 3,000,000
Shares at $53.31 per Share. This offering included 500,000 Shares sold by
pcOrder and 2,500,000 Shares sold by selling stockholders, including 2,333,000
Shares sold by Trilogy. As a result of this offering, Trilogy's ownership in
pcOrder was reduced to approximately 62% of the outstanding shares of pcOrder's
capital stock and 93% of pcOrder's aggregate voting power.

   During the first quarter of 2000, pcOrder's Share price began to decline
steeply from the price of the December 1999 public offering, and, by the end of
March 2000, the Share price was consistently trading in the low $20s.


                                       8

   During February 2000, pcOrder's management began to consider strategic
alternatives for pcOrder in light of its declining stock price, increasing
competition, and continued financial losses.

   During this period, pcOrder was also attempting to bolster its management
team in order to improve operations and hired a new Vice President of Marketing
in February 2000.

   pcOrder incurred an operating loss of approximately $3.6 million in the
first quarter of 2000. During this period, pcOrder did not acquire any
significant new software customers.

   Effective March 31, 2000, pcOrder's Chief Financial Officer resigned

   During the second quarter of 2000, pcOrder's management continued to
evaluate strategic alternatives and began to initiate calls with third parties
regarding partnering with pcOrder or acquiring pcOrder's content business or
all of pcOrder. During this period several third parties unaffiliated with
Trilogy were contacted about the possibility of entering into a transaction
with pcOrder. The parties contacted were mainly media and enterprise software
companies. pcOrder provided information to, and engaged in preliminary
discussions with, some of these third parties. Such discussions never advanced
to a serious level, except that multiple discussions and contract negotiations
were held with one party interested in acquiring the content business of
pcOrder but those negotiations broke off because of business issues. That party
expressed a lack of interest in acquiring the entire pcOrder business.

   Also, during the second quarter of 2000, pcOrder continued to try to improve
its operations, including by bolstering its management team. pcOrder hired new
Vice Presidents in charge of Content, Engineering, and Talent during this
period. No replacement Chief Financial Officer had yet been identified. pcOrder
also considered hiring a Chief Operations Officer to take on some of the
responsibilities of, and to split the role from, that of the President. A
search for a Chief Operations Officer was commenced. During this period,
pcOrder did not acquire any significant new software customers.

   By June 2000, the Shares were consistently trading in the single digits.

   pcOrder incurred an operating loss of approximately $3.4 million in the
second quarter of 2000. In its second quarter earnings call, pcOrder announced
that revenues were expected to decline 15-20% in the last six months of 2000.
In light of the reduced projected revenues, pcOrder began to explore
alternatives to reduce operating expenses, including reducing its work force
and discontinuing certain lines of business, in addition to considering
business combinations and other alternatives.

   In July 2000, CNET announced the acquisition of Apollo Solutions, Inc.
("Apollo"), a competitor of pcOrder's community business. Also, in July 2000,
CNET and Ziff-Davis, Inc. ("ZDNet") announced that they were merging. These
mergers eroded possible partnership opportunities for pcOrder as CNET became a
provider of a broader range of services than any of CNET, Apollo or ZDNet
offered on its own and became the dominant IT media portal.

   At a meeting of the Board of Directors of Trilogy (the "Trilogy Board") on
July 27, 2000, Joseph A. Liemandt, the Chairman of the Trilogy Board, reported
to the Trilogy Board that pcOrder was considering several alternative courses
of action to remedy perceived problems with pcOrder's operations and financial
performance. Mr. Liemandt indicated that among the alternatives being
considered by pcOrder to reduce pcOrder's operating expenses and help pcOrder
achieve profitability were a reduction in the size of pcOrder's workforce and
the discontinuance of certain lines of business.

   On August 24, 2000, Mr. Liemandt, and a representative of Trilogy's senior
management met with Trilogy's outside counsel, Haynes and Boone, LLP, to
discuss generally pcOrder's continuing operational and financial difficulties,
Trilogy's duties as a controlling stockholder of pcOrder and the advantages and
disadvantages of appointing a special committee of the Trilogy Board to analyze
strategic alternatives with

                                       9
<PAGE>

respect to Trilogy's ownership interest in pcOrder. At this meeting, the
advisability of hiring a financial advisor to advise any such special committee
of the Trilogy Board was also discussed.

   On August 28 and 29, 2000, in a series of telephone calls, members of the
Trilogy Board informally discussed the advisability of forming a special
committee of the Trilogy Board and the composition of such special committee.
The Trilogy Board agreed to form a special committee of the Trilogy Board (the
"Trilogy Special Committee") and further agreed that the Trilogy Special
Committee would consist of Dennis R. Cassell, who is also a partner of
Trilogy's outside counsel, Haynes and Boone, LLP, Charles I. Frumberg, Arthur
J. Marks and Henry F. McCance. It was determined that it was not advisable to
appoint either Joseph A. Liemandt or Diane R. Liemandt to the Trilogy Special
Committee in view of Mr. Liemandt's role as a director of pcOrder and the
family relationship between him and Ms. Liemandt. The establishment of the
Trilogy Special Committee was formally memorialized by a unanimous written
consent of the Trilogy Board on August 30, 2000. In the unanimous written
consent, the Trilogy Special Committee was authorized to engage legal counsel
and independent financial advisors, evaluate pcOrder's business, consider such
alternatives as may be presented to the Trilogy Special Committee by legal
counsel and independent financial advisors and to make recommendations to the
Trilogy Board with respect thereto.

   Following their appointment, in a series of telephone calls, the Trilogy
Special Committee discussed the selection of a financial advisor. Following
discussion of the qualifications of SG Cowen and Mr. Frumberg's relationship
with SG Cowen, and after a telephone interview by one member of the Trilogy
Special Committee, the Trilogy Special Committee determined to retain SG Cowen
Securities as its financial advisor. SG Cowen is also acting as Dealer Manager
in connection with the Offer.

   On August 29, 2000, Mr. Cassell notified Richard Friedman, Vice President,
General Counsel and Secretary of pcOrder, that the Trilogy Special Committee
planned to retain investment bankers to conduct a due diligence review of
pcOrder in order to help Trilogy evaluate its investment in pcOrder.

   From August 29 to September 11, 2000, pcOrder management and directors held
several informal discussions regarding the Trilogy request. During this period,
pcOrder management continued to evaluate its strategic alternatives and had
further discussions with two third parties, which had been contacted earlier in
the year, to determine if any interest had developed in a possible business
combination.

   From approximately September 5, 2000, through September 27, 2000, the
Trilogy Special Committee and its advisors agreed upon the terms of the
engagement of its financial advisors, reviewed certain public information with
respect to pcOrder and entered into preliminary discussions with
representatives of pcOrder regarding Trilogy's proposed due diligence review of
pcOrder.

   On September 10, 2000, Robert W. Stearns and Linwood A. Lacy, independent
directors of pcOrder, met with representatives of the law firm of Gray Cary
Ware & Freidenrich LLP ("Gray Cary") to discuss the possible retention of Gray
Cary as counsel to a special committee of the pcOrder Board, if such a
committee were formed.

   On September 12, 2000, the pcOrder Board met to discuss the request by
Trilogy to allow Trilogy's financial advisors to conduct a due diligence review
of pcOrder. It discussed the possibility of forming a special committee of
independent directors to evaluate strategic alternatives. Representatives of
Gray Cary attended the meeting. The pcOrder Board requested that it be
presented with additional information regarding the consideration of strategic
alternatives at a September 20, 2000 pcOrder Board meeting. The pcOrder Board
also decided to further consider forming a special committee at the September
20, 2000 Board meeting.

   On September 15, 2000, after lengthy discussions, pcOrder agreed to an
amended contract with its largest customer, Compaq Computer Corporation, which
provided, among other changes, that Compaq could terminate its contract one
year earlier than it could under the original contract or elect to reduce the
scope of its license and the related license fees.

                                       10
<PAGE>

   On September 20, 2000, pcOrder management presented an internal
restructuring plan to the pcOrder Board as part of the Board's evaluation of
strategic alternatives. This plan included the refocusing of pcOrder on its
enterprise software business with a reduced workforce and a discontinuation of
its involvement in the content and community businesses. See "--Certain
Financial Projections". The status of the search for a replacement Chief
Financial Officer and a Chief Operations Officer to assume some of the
responsibilities of the President were also discussed. The pcOrder Board formed
the pcOrder Special Committee, consisting of independent directors Mr. Stearns
and Mr. Lacy, to evaluate strategic alternatives for pcOrder. The pcOrder
Special Committee was authorized to investigate and make recommendations to the
pcOrder Board regarding strategic alternatives for pcOrder, including mergers,
acquisitions, restructurings, divestitures, and other transactions, which may
or may not involve Trilogy, that may bring value to pcOrder's stockholders. The
pcOrder Special Committee was authorized expressly to decline to recommend any
transaction proposed by Trilogy if the pcOrder Special Committee determined
that such transaction was not in the best interests of pcOrder's other
stockholders. The pcOrder Special Committee was also authorized to retain, at
pcOrder's expense, such financial, legal and other advisors as the pcOrder
Special Committee deemed appropriate in connection with its analysis.

  On September 20, 2000, the pcOrder Special Committee met with representatives
of Gray Cary and confirmed the retention of that firm as its counsel. The
pcOrder Special Committee also discussed the hiring of an investment banking
firm to serve as financial advisor to the pcOrder Special Committee and
authorized Gray Cary to contact two specific firms.

   After being engaged on September 20, 2000, Gray Cary, on behalf of the
pcOrder Special Committee, contacted the two investment banking firms
identified during the September 20 pcOrder Special Committee meeting about each
firm's possible interest in being engaged to advise the pcOrder Special
Committee. Gray Cary also engaged special Delaware legal counsel to represent
the pcOrder Special Committee.

   From September 20 to September 27, 2000, the pcOrder Special Committee and
Gray Cary discussed various strategic alternatives and, on September 27, after
a presentation by DRW and an interview of that firm's representatives by the
pcOrder Special Committee, DRW was engaged as financial advisor to the pcOrder
Special Committee. On that date, the pcOrder Special Committee also discussed
the terms of a proposed confidentiality agreement to be entered into by
pcOrder, Trilogy, and SG Cowen, in connection with pcOrder providing Trilogy
and SG Cowen non-public information regarding pcOrder to be used by them in
evaluating strategic alternatives regarding Trilogy's investment in pcOrder.
The pcOrder Special Committee authorized the negotiation, execution, and
delivery of the confidentiality agreement. During this period, the pcOrder
Special Committee was informed that pcOrder's Vice President of Finance
intended to leave in the near future and that other key personnel had indicated
an intention to leave pcOrder if pcOrder was not sold or if it embarked on a
stand-alone strategy as an enterprise software company. During this same
period, pcOrder's management continued to try to engage two third parties in
discussions regarding a possible business combination with pcOrder. No
indications of interest were received from those parties.

   On September 27, 2000, representatives of DRW and Gray Cary met with various
members of pcOrder management to obtain non-public information about pcOrder's
business and its prospects.

   On September 28, 2000, the confidentiality agreement among pcOrder, Trilogy
and SG Cowen was executed and a member of the Trilogy Special Committee orally
indicated to the legal and financial advisors of the pcOrder Special Committee
that Trilogy would not initiate discussions with third parties regarding a
potential sale of pcOrder or Trilogy's ownership interest in pcOrder without
first discussing the possibility of doing so with the pcOrder Special
Committee. Following the execution of the confidentiality agreement,
representatives of the financial advisors and legal counsel of both the pcOrder
Special Committee and the Trilogy Special Committee met with various members of
pcOrder management to obtain non-public information about pcOrder's business
and its prospects. pcOrder also provided the financial advisors and legal
counsel of both parties with such written due diligence materials as they
requested.

                                       11
<PAGE>

   On October 1, 2000, the pcOrder Special Committee met with its financial
advisors and legal counsel to discuss strategic alternatives. Representatives
of Gray Cary gave a presentation regarding the terms of the executed
confidentiality agreement with Trilogy and SG Cowen. The pcOrder Special
Committee also discussed employee retention at pcOrder and the status of the
Chief Financial Officer and Chief Operations Officer searches.

   From October 1 through October 15, the pcOrder Special Committee received
several reports from its financial advisors and legal counsel on matters
relevant to the pcOrder Special Committee's deliberations, including their
interviews with various members of pcOrder's management and periodic
discussions with the financial advisors and legal counsel to Trilogy. During
this period, the pcOrder Special Committee held several formal meetings with
its advisors and conferred regularly with them informally through Mr. Stearns,
its Chairman. In these meetings and discussions, the pcOrder Special Committee
received advice pertaining to its deliberations and strategic alternatives,
including:

  .  the difficulties in marketing pcOrder to third parties even with the
     active assistance of Trilogy (which, the pcOrder Special Committee
     recognized, Trilogy had indicated its willingness to provide) due to
     Trilogy's controlling interest, and the interrelationship and, in
     certain cases, joint ownership of the companies' intellectual property
     rights; and

  .  the prospects of pcOrder continuing as a stand-alone entity.

   During this period, the pcOrder Special Committee continued to receive
reports that employee retention was a major concern to management and that if a
clear statement regarding the direction of pcOrder was not announced by October
26, 2000, the scheduled date for pcOrder's third quarter earnings release,
additional employees were expected to leave. pcOrder's Chief Executive Officer
also gave notice of his intention to resign effective as of the expiration of
his employment agreement on November 1, 2000. (However, in connection with the
pcOrder Board's decision to approve the Merger Agreement, the Chief Executive
Officer agreed to remain with pcOrder through the process of closing the Offer
and the Merger.)

   On October 10, 2000, at a meeting of the Trilogy Special Committee, SG Cowen
made a presentation to the Trilogy Special Committee regarding four separate
alternatives with respect to Trilogy's ownership interest in pcOrder. The four
alternatives were:

  .  maintain the status quo and do nothing;

  .  implement a restructuring program while keeping pcOrder as a separate
     entity;

  .  acquire pcOrder; and

  .  sell pcOrder to a third party.

After discussing the four alternatives with SG Cowen and legal counsel, the
Trilogy Special Committee decided to recommend to the Trilogy Board that
Trilogy acquire pcOrder.

   Following the meeting of the Trilogy Special Committee, the Trilogy Board
had a discussion on October 10, 2000. The members of the Trilogy Special
Committee recommended that Trilogy acquire pcOrder. The Trilogy Board
authorized management of Trilogy to pursue negotiations with pcOrder to
determine the optimal structure for an acquisition of pcOrder and to pursue
negotiations with pcOrder to acquire pcOrder.

   On October 12, 2000, Trilogy's financial advisors and legal counsel reviewed
the results of their due diligence investigation with members of Trilogy's
senior management. Trilogy's legal counsel then recommended a structure for a
proposed transaction to acquire pcOrder and the meeting participants determined
the economic terms for an acquisition proposal to pcOrder's Special Committee.

   On October 13, 2000, the Trilogy Board had another discussion at which
Trilogy's financial and legal advisors and members of Trilogy management
recommended the form of transaction and economic terms of a proposed offer to
acquire pcOrder. The Trilogy Board authorized their financial advisors and
legal counsel to convey the proposed offer to the pcOrder Special Committee and
its advisors.

                                       12
<PAGE>

   On October 17, 2000, at the request of Trilogy's legal counsel, the pcOrder
Special Committee's financial advisors and legal counsel met with Trilogy's
financial advisors and legal counsel to discuss the proposed acquisition of
pcOrder by Trilogy. Trilogy's financial advisors summarized the results of
their review of pcOrder and Trilogy's representatives informed pcOrder's
representatives of Trilogy's desire to acquire pcOrder. Trilogy's
representatives and pcOrder's representatives then discussed the advantages and
disadvantages of alternative acquisition structures and ultimately concluded
that any acquisition of pcOrder by Trilogy should be structured as a cash
tender offer for all outstanding Shares, followed by a second step merger in
which any holder of Shares that did not tender such Shares in the tender offer
would receive, in exchange for such Shares, the same per Share cash
consideration as paid in the tender offer. The meeting included a discussion of
allowing pcOrder to consider competing transactions with any interested third
parties. The advisors of both parties discussed the problems with pcOrder
attempting to seek third party buyers without Trilogy's active participation
due to Trilogy's controlling ownership interest and the joint ownership and
interrelationship of the parties' intellectual property. The respective
advisors also discussed recent departures by key pcOrder personnel and concerns
about other expected departures.

   Later that same day, at the request of the Trilogy Board, Trilogy's
financial advisors and legal counsel indicated to the pcOrder Special
Committee's representatives that Trilogy would be willing to pay $5.00 per
Share to acquire pcOrder. The pcOrder Special Committee's representatives
indicated that they would communicate the $5.00 per Share proposal to the
pcOrder Special Committee. After that meeting, the pcOrder Special Committee
met to discuss the proposal and a range of possible responses.

   On October 18, 2000, the pcOrder Special Committee met with its legal and
financial advisors to again discuss the Trilogy proposal of $5.00 per Share and
the range of possible responses. The pcOrder Special Committee reviewed the
business and prospects of pcOrder and received from DRW an update of its
ongoing work in connection with pcOrder. After the discussions, the pcOrder
Special Committee directed its advisors to make an $8.00 per Share
counterproposal to Trilogy.

   On October 19, 2000, representatives of the financial advisors and legal
counsel to the pcOrder Special Committee again met with representatives of the
legal counsel and financial advisors to Trilogy. The pcOrder Special
Committee's advisors indicated that $5.00 per Share was insufficient and
discussed the reasons for that conclusion. They then made a counterproposal of
$8.00 per Share. Trilogy's advisors indicated that Trilogy believed that $8.00
per Share was much too high and discussed reasons for that conclusion,
including a current stock price of slightly over $3.00 per Share and pcOrder's
deteriorating financial condition and operations. Trilogy's advisors indicated
that Trilogy was willing to pay $5.50 per Share. The various representatives
also discussed other terms of the proposed transaction, including that the
agreement would contain no lock-ups or break-up fees other than a $1.25 million
expense reimbursement if pcOrder terminated the agreement. The pcOrder Special
Committee's advisors indicated that the pcOrder Special Committee might be
willing to approve an agreement that had those features if the price per Share
was at least $6.00 and were advised by Trilogy's advisors that a price of $6.00
would be acceptable to Trilogy if a definitive agreement could be concluded
promptly.

   Over the next two days, the advisors to the pcOrder Special Committee
conferred with the pcOrder Special Committee regarding the possibility of
concluding an agreement with Trilogy at the $6.00 per Share price discussed at
the October 19, 2000 meeting. The pcOrder Special Committee decided that it
would not be willing to recommend that price to the pcOrder Board and
instructed its advisors to convey to Trilogy's advisors that the pcOrder
Special Committee required a price of at least $6.50. This was communicated to
counsel for Trilogy on October 21, 2000 following which negotiations continued
for a further two days during which additional counterproposals were made by
each party and various terms of the proposed transaction were discussed. On
October 23, 2000, the pcOrder Special Committee and Trilogy agreed to a price
of $6.375 per share, subject to negotiating all of the provisions of a mutually
acceptable definitive merger agreement and the approval of that agreement by
the Boards of both companies.

                                       13

   Thereafter, from the afternoon of October 23, 2000, until the evening of
October 24, 2000, legal counsel for Trilogy and legal counsel for the pcOrder
Special Committee negotiated the terms of the Merger Agreement and discussed
the unresolved issues.

   On October 24, 2000, the Trilogy Board met with its advisors to review the
draft Merger Agreement and to discuss the terms of the Offer and the Merger, as
contemplated by the draft Merger Agreement. After receiving presentations and
advice from its financial advisor and legal counsel, the Trilogy Board
unanimously approved the Merger Agreement, subject to any required changes
approved by Trilogy's officers to resolve any remaining open issues.

   Later on October 24, 2000, the pcOrder Special Committee met with its
advisors to review the draft Merger Agreement and to discuss the terms of the
Offer and the Merger, as contemplated by the draft Merger Agreement. Additional
changes to the draft Merger Agreement that had resulted from further
negotiations were also discussed. It was reported that the Trilogy Board had
approved the draft Merger Agreement earlier that day. DRW then reviewed its
financial analysis of the $6.375 Offer Price and delivered its oral fairness
opinion (later confirmed in writing) to the effect that, as of such date and
subject to the qualifications, assumptions and limitations stated in the
opinion, the Offer Price was fair to the Unaffiliated Stockholders from a
financial point of view. See "--Opinion of Financial Advisor to the pcOrder
Special Committee." After further discussions and receiving such advice from
its advisors as it deemed necessary, the pcOrder Special Committee resolved
unanimously to recommend Trilogy's offer to the pcOrder Board. See "--
Recommendation of the pcOrder Special Committee and the pcOrder Board; Fairness
of the Offer and the Merger--the pcOrder Special Committee" and "--Opinion of
Financial Advisor to the pcOrder Special Committee."

   Following the meeting of the pcOrder Special Committee on October 24, 2000,
the pcOrder Board met and received a report from the pcOrder Special Committee
regarding its recommendation. Mr. Liemandt, Chief Executive Officer of Trilogy,
was not present. The pcOrder Board discussed the proposed transaction and the
draft Merger Agreement with the pcOrder Special Committee and its advisors. DRW
again reviewed its financial analysis of the Offer Price, confirmed its oral
fairness opinion and orally advised that its written fairness opinion would
also be given to the pcOrder Board. Mr. Barris recused himself from the vote on
the Merger Agreement because the venture capital firm in which he is a partner
holds shares of Trilogy stock and one of his partners is a member of the
Trilogy Board. The remaining members of the pcOrder Board, having determined
that the Offer and the Merger were fair to and in the best interests of, the
Unaffiliated Stockholders, then unanimously accepted the pcOrder Special
Committee's recommendation, adopted and approved the Merger Agreement and the
transactions it contemplated, and resolved to recommend that pcOrder's
stockholders accept the Offer and tender their shares pursuant to the Offer.
See "--Recommendation of the pcOrder Special Committee and the pcOrder Board;
Fairness of the Offer and the Merger--the pcOrder Board."

   On October 25, 2000, following conclusion of the pcOrder Board meeting, and
prior to the opening of trading on the U.S. stock markets, the Merger Agreement
was finalized and executed and that execution was announced in a joint press
release of pcOrder and Trilogy.

RECOMMENDATION OF THE PCORDER SPECIAL COMMITTEE AND THE PCORDER BOARD; FAIRNESS
OF THE OFFER AND THE MERGER

   THE PCORDER SPECIAL COMMITTEE. At a meeting on October 24, 2000, the pcOrder
Special Committee unanimously determined, pursuant to the authority conferred
on the pcOrder Special Committee by the pcOrder Board, to recommend to the
pcOrder Board that the pcOrder Board:

  .  determine that each of the Offer and the Merger is fair to and in the
     best interests of the Unaffiliated Stockholders;

  .  approve the Merger Agreement and the transactions it contemplates,
     including the Offer and the Merger; and

  .  resolve to recommend that pcOrder's stockholders accept the Offer and
     tender their Shares in the Offer.

                                       14

   The recommendation of the pcOrder Special Committee was made and accepted at
a meeting of the pcOrder Board held after the pcOrder Special Committee meeting
on October 24, 2000. See "--The pcOrder Board."

   In deciding to make its recommendation, the pcOrder Special Committee
considered the factors listed below. The following discussion of the factors
considered by the pcOrder Special Committee is not intended to be exhaustive
but summarizes all material factors considered. The pcOrder Special Committee
did not assign any relative or specific weights to the following factors nor
did it specifically characterize any factor as positive or negative, except as
described below. In addition, individual members of the pcOrder Special
Committee may have given differing weights to differing factors and may have
viewed certain factors more positively or negatively than others. Throughout
its deliberations, the pcOrder Special Committee received the advice of its
financial advisors and legal counsel.

   Insofar as the following discussion of the factors considered by the pcOrder
Special Committee:

  .  refers to information that came to the pcOrder Special Committee's
     attention during its evaluation of the acquisition proposal and the
     negotiations conducted with Trilogy and its advisors, as well as
     existing agreements between pcOrder and Trilogy, reference is also made
     to the more detailed information contained under "--Background of the
     Offer and the Merger" and "--Related Party Transactions;"

  .  refers to provisions of the Merger Agreement, including the conditions
     to the Merger, reference is also made to the more detailed information
     contained under "--The Merger Agreement;"

  .  refers to the historical and projected financial results of pcOrder,
     including the reorganization plan described below, reference is also
     made to the more detailed information contained under "--Certain
     Financial Projections," and "The Tender Offer-- Section 7. Certain
     Information Concerning pcOrder;"

  .  refers to the opinion of DRW, reference is also made to "--Opinion of
     Financial Advisor to the pcOrder Special Committee" and Annex B hereto;
     and

  .  refers to the conditions of the Offer, reference is also made to "The
     Tender Offer--Section 13. Certain Conditions of the Offer."

   pcOrder's Deteriorating Financial Condition. The pcOrder Special Committee
   --------------------------------------------
considered the financial condition and prospects of pcOrder. This consideration
included the fact that pcOrder had incurred substantial operating losses for
more than the last four years, and was projecting that it would continue to
incur substantial operating losses in the fourth quarter of 2000 and each
quarter in 2001, notwithstanding the technical and administrative support
provided by Trilogy and the various changes that had occurred in pcOrder's
senior management since February 2000. The pcOrder Special Committee also noted
that pcOrder only had eight substantial customers on the enterprise software
side of the business and, on an aggregate basis, those customers' contracts
would provide negative future cash flows. The pcOrder Special Committee also
considered that pcOrder had acquired no significant new software customers in
the past nine months. These considerations were in addition to the detailed
financial information that had been regularly furnished to the members of the
pcOrder Special Committee, in their respective capacities as members of the
pcOrder Board and its Audit Committee, by pcOrder's senior management and the
general familiarity of the members of the pcOrder Special Committee with the
affairs of pcOrder.

   The pcOrder Special Committee also considered the fact that employee
turnover had been high for several months and several additional key employees,
including the Chief Executive Officer and the Vice President of Finance, were
expected to leave in the next few weeks.

                                       15
<PAGE>

   Absence of Better Alternatives. The pcOrder Special Committee noted that
   -------------------------------
pcOrder's management had been seeking strategic partners or third parties to
acquire pcOrder for several months and had generated no interest. The pcOrder
Special Committee also noted that serious discussions regarding the sale of
pcOrder could not occur even with the active participation of Trilogy (which,
the pcOrder Special Committee recognized, Trilogy had indicated its willingness
to provide) because of:

  .  Trilogy's ownership of a majority of pcOrder's capital stock; and

  .  the interrelationship and, in certain cases, joint ownership of
     Trilogy's and pcOrder's intellectual property.

   The pcOrder Special Committee also considered the fact that pcOrder's senior
management had developed a restructuring plan involving refocusing pcOrder on
its enterprise software business with a reduced workforce and a discontinuation
of its involvement in the content and community businesses . For additional
information regarding the reorganization plan, see "--Certain Financial
Projections." The pcOrder Special Committee concluded that:

  .  there was considerable doubt as to whether the restructuring plan would
     be successful in turning around the company;

  .  there was substantial uncertainty as to the extent and timing of the
     intended positive effects of the restructuring plan;

  .  even if the restructuring plan were successfully implemented, it did not
     contemplate pcOrder turning an operating profit during 2001; and

  .  there was substantial risk that the restructuring plan would not result
     in enhancement of stockholder value in the foreseeable future.

   For all of these reasons, the pcOrder Special Committee concluded that the
possibility of pcOrder successfully implementing the restructuring plan did not
warrant any delay in acting on the Merger Agreement.

   The pcOrder Special Committee concluded that, in the absence of a
transaction that afforded the Unaffiliated Stockholders the opportunity to sell
or exchange their shares for cash at the Offer Price, and taking into account
the risk that no other proposal for the acquisition of the Shares would be
forthcoming in the foreseeable future, pcOrder's stockholders were confronted
with two disadvantageous alternatives, namely:

  .  retaining their Shares and subjecting themselves to the significant risk
     that their Shares might decline in value, and might conceivably be
     rendered virtually worthless in the event that pcOrder continued to use
     more cash than it generated; or

  .  selling their Shares into a market which, in the absence of the pendency
     of the acquisition proposal, and having regard to pcOrder's substantial
     continuing and projected operating losses and the uncertainties that the
     market was likely to perceive in the extent and timing of the positive
     effects of the reorganization plan, might price the Shares at a level
     below the level at which the Shares were then trading and the price
     might conceivably fall to substantially below that level if pcOrder
     continued to report losses and deplete its cash reserves.

   The pcOrder Special Committee determined that a transaction with Trilogy at
the Offer Price of $6.375 (see "--Fairness of the Offer Price") and on the
other terms set forth in the Merger Agreement (see "--Absence of Prohibitions
on Responding to Third-Party Bidders" and "--Likelihood of Consummation"), was
a preferable alternative that subjected pcOrder stockholders to substantially
less risk than would be created by rejecting the proposed Offer and Merger and
discontinuing negotiations with Trilogy.

                                       16
<PAGE>

   In concluding that no preferable alternative to the Offer and the Merger had
emerged, the pcOrder Special Committee also took note of the following factors:

  .  the fact that the pcOrder Special Committee had been successful, through
     active and vigorous negotiations conducted on an arm's-length basis, in
     obtaining an increase of $1.375, or 27.5%, per Share, in the price
     offered by Trilogy from the price per Share initially proposed;

  .  the fact that pcOrder relies on Trilogy for substantial customer support
     and product development personnel and administrative functions;

  .  the fact that a substantial part of pcOrder's products rely on Trilogy
     technology, some of which would be very difficult or expensive to
     replace;

  .  the fact that pcOrder was subject to ever-increasing competitive
     pressures;

  .  the fact that competitive and business pressures in the computer
     industry channel and a general downturn in the prospects for online
     businesses were resulting in an increasing number of pcOrder's customers
     and potential customers going out of business, consolidating with other
     companies or experiencing a deteriorating financial condition; and

  .  the fact that Trilogy's negotiating team had informed pcOrder's
     negotiating team on October 23, 2000, that $6.375 per share was
     Trilogy's final offer and that this price exceeded the offer price that
     Trilogy considered justified by objective factors.

   The pcOrder Special Committee concluded that, in light of pcOrder's
deteriorating financial condition (see "--pcOrder's Deteriorating Financial
Condition"), the risks to pcOrder's stockholders from rejecting Trilogy's final
offer and discontinuing the negotiations outweighed the seemingly remote
possibility that Trilogy might be willing to continue negotiations and that
such continued negotiations might result in improved terms.

   Fairness of the Offer Price. The pcOrder Special Committee took into account
   ----------------------------
the oral opinion of DRW that, as of the date on which the pcOrder Special
Committee made its recommendation, the Offer Price proposed in the Offer and
the Merger was fair, from a financial point of view, to the Unaffiliated
Stockholders. DRW subsequently confirmed this opinion in writing. See "--
Opinion of Financial Advisor to the pcOrder Special Committee" for a
description of this opinion and the analysis of DRW in arriving at its opinion.
A copy of the DRW opinion, setting forth the assumptions made, matters
considered and review undertaken is attached hereto as Annex B. The full text
of such opinion is incorporated herein by reference and the foregoing
description thereof is qualified in its entirety by this reference.
Stockholders are urged to read such opinion carefully in its entirety.

   The pcOrder Special Committee also took account of the methodology employed
by DRW as a basis for its fairness opinion, including the financial data
presented to DRW by pcOrder to assist in DRW's analysis.

   The pcOrder Special Committee noted that it was unlikely that the market
price of the Shares would attain the $6.375 per Share level of the Offer Price
unless and until pcOrder began to generate operating profits, which pcOrder had
yet to do and the attainment of which was therefore subject to substantial
uncertainty, even assuming that pcOrder was able to implement the restructuring
plan (see "--Absence of Better Alternatives").

   On the basis of this information and DRW's oral opinion, and taking into
account the fact that the Offer Price represented a premium of approximately
85% over the closing of Shares on Nasdaq's National Market System on the day of
its deliberations, the pcOrder Special Committee concluded that the Offer Price
was fair under all of the relevant circumstances, including pcOrder's
deteriorating financial condition (see "--pcOrder's Deteriorating Financial
Condition"), the lack of better alternatives (see"--Absence of Better
Alternatives"), the lack of prohibitions on responding to subsequent third-
party bidders (see "--Absence of Prohibitions on Responding to Third-Party
Bidders") and the likelihood of consummation (see "--Likelihood of
Consummation").

                                       17
<PAGE>

   Absence of Prohibitions on Responding to Third-Party Bidders. The pcOrder
   -------------------------------------------------------------
Special Committee took into consideration that the Merger Agreement contained
no covenants prohibiting subsequent third-party bids for pcOrder. It also noted
that the Merger Agreement provided only for a modest expense reimbursement of
$1.25 million payable by pcOrder to Trilogy if pcOrder terminated the Merger
Agreement to pursue a superior offer. Based on this information, and the
information described in "--pcOrder's Deteriorating Financial Condition," "--
Absence of Better Alternatives," "--Fairness of the Offer Price" and "--
Likelihood of Consummation," the pcOrder Special Committee concluded that there
was no reason to delay approving the Merger Agreement to continue looking for a
third-party bidder.

   Likelihood of Consummation. The pcOrder Special Committee took into
   ---------------------------
consideration the totality of the terms of the Merger Agreement and concluded
that they were such as to maximize the likelihood of the consummation of the
Offer and the Merger.

   Among other things, the pcOrder Special Committee took note of the
following:

  .  The fact that Trilogy was willing to effect the transaction through the
     first-step Offer, under the terms of which it was willing to accept any
     and all validly tendered Shares, followed by the second-step Merger at
     the same price. As a result of this two-step structure, there was a
     reasonable possibility that the pcOrder stockholders could sell their
     Shares to Trilogy at the Offer Price earlier than if the transaction
     were effected as a one-step merger.

  .  The fact that the conditions to Trilogy's obligations to consummate the
     Offer were customary and, in the assessment of the pcOrder Special
     Committee, not unduly onerous.

  .  The fact that Trilogy was willing, pursuant to the Merger, to pay the
     Offer Price for all Shares not purchased pursuant to the Offer and that,
     if the Offer were consummated, there would be no conditions to Trilogy's
     obligation to consummate the Merger other than the absence of a legal
     prohibition.

  .  The fact that, to the extent that any pcOrder stockholders chose not to
     tender their Shares into the Offer or accept the Offer Price pursuant to
     the Merger but, rather, exercised statutory appraisal rights under
     Delaware law (see "--Dissenters' Rights"), such exercise would not
     impair Trilogy's obligation to consummate the Merger, provided the Offer
     was consummated. Accordingly, those pcOrder stockholders who believed
     that the exercise of statutory appraisal rights would yield them a
     greater per Share amount than the Offer Price would be free to pursue
     such exercise without adversely affecting the ability of the other
     pcOrder stockholders to receive the Offer Price for their Shares.

   The pcOrder Special Committee also took note of the fact that the
limitations to be imposed by the Merger Agreement on the conduct of business by
pcOrder prior to the consummation of the Offer would not preclude pcOrder from
implementing measures to improve its operating results during the pendency of
the Offer because those conditions would not apply to actions which either (a)
were approved by Trilogy or (b) were in the ordinary and usual course of
pcOrder's business consistent with past practice. Thus, the Merger Agreement
would not subject the pcOrder stockholders to an undesirable risk that, if the
Merger Agreement were terminated, pcOrder would be in worse financial condition
by reason of the very execution of the Merger Agreement because pcOrder had
been unable to implement measures to improve its operating results during the
pendency of the Offer.

   The pcOrder Special Committee also took account of the fact that Trilogy was
willing to represent, in the Merger Agreement, that it had available sources of
financing to consummate the Offer and the Merger without
resort to pcOrder's assets or borrowings secured by pcOrder's assets.
Accordingly, the financing of the Offer and the Merger would not be dependent
on, or adversely affected by any further deterioration in, pcOrder's financial
condition.

                                       18
<PAGE>

   The pcOrder Special Committee also took into consideration the fact that
Trilogy was willing to agree that (a) it would not take any action to remove
from office or impair the authority of any member of the pcOrder Special
Committee and (b) all of the rights of pcOrder under the Merger Agreement,
including, without limitation, rights of waiver and enforcement, would be
vested exclusively in the pcOrder Special Committee and would be exercisable
only with the consent of, or at the express direction, of the pcOrder Special
Committee. In the view of the pcOrder Special Committee, this provision was
significant in ensuring that the fact that Trilogy's stock ownership in pcOrder
gave it the power to remove the current pcOrder Board would not preclude
pcOrder, through the pcOrder Special Committee, from taking such action as
might be appropriate to seek to ensure that Trilogy's obligations under the
Merger Agreement were satisfied and pcOrder's rights thereunder were enforced.

  FOR THE FOREGOING REASONS, ON OCTOBER 24, 2000, THE PCORDER SPECIAL COMMITTEE
UNANIMOUSLY DETERMINED, PURSUANT TO THE AUTHORITY CONFERRED ON THE PCORDER
SPECIAL COMMITTEE BY THE PCORDER BOARD, TO RECOMMEND TO THE PCORDER BOARD THAT
THE PCORDER BOARD:

  .  DETERMINE THAT EACH OF THE OFFER AND THE MERGER IS FAIR TO AND IN THE
     BEST INTERESTS OF UNAFFILIATED STOCKHOLDERS;

  .  APPROVE THE MERGER AGREEMENT AND THE TRANSACTIONS IT CONTEMPLATES,
     INCLUDING THE OFFER AND THE MERGER; AND

  .  RESOLVE TO RECOMMEND THAT PCORDER'S STOCKHOLDERS ACCEPT THE OFFER AND
     TENDER THEIR SHARES IN THE OFFER.

  THE PCORDER BOARD.  At a meeting on October 24, 2000, immediately following
the pcOrder Special Committee meeting (see "--The pcOrder Special Committee"),
the pcOrder Board (unanimously, except as noted below):


  .  determined that each of the Offer and the Merger is fair to and in the
     best interests of the Unaffiliated Stockholders;

  .  approved the Merger Agreement and the transactions it contemplates,
     including the Offer and the Merger; and

  .  resolved to recommend that pcOrder's stockholders accept the Offer and
     tender their Shares in the Offer.

Joseph A. Liemandt, Chairman and Chief Executive Officer and majority
stockholder of Trilogy's parent, was not present at the meeting and Peter J.
Barris recused himself from the vote because the venture capital firm in which
he is a partner owns stock in Trilogy and one of his partners is a member of
the Trilogy Board.

   In reaching its decision, the pcOrder Board considered the factors listed
below. The following discussion of the factors considered by the pcOrder Board
is not intended to be exhaustive but summarizes all material factors
considered, except that, in the case of the two members of the pcOrder Board
who are also members of the pcOrder Special Committee, reference is also made
to the discussion above regarding the factors considered by the pcOrder Special
Committee. See "--The pcOrder Special Committee." The pcOrder Board did not
assign any relative or specific weights to the following factors nor did it
specifically characterize any factor as positive or negative and individual
members of the pcOrder Board may have given differing weights to differing
factors and may have viewed certain factors more positively or negatively than
others. Throughout its deliberations, the pcOrder Board received the advice of
pcOrder's General Counsel.

                                       19
<PAGE>

   The pcOrder Board took into consideration the report it had received during
its October 24, 2000 meeting regarding the pcOrder Special Committee's
recommendation regarding the Merger Agreement, the Offer and
the Merger (see "--Background of the Offer and the Merger"), and regarding the
nature and scope of the pcOrder Special Committee's work underlying that
recommendation, including, among other things:

  .  the pcOrder Special Committee's negotiations with Trilogy;

  .  the respective positions taken by the parties during those negotiations;
     and

  .  the fact that the pcOrder Special Committee had received from DRW an
     oral opinion that, as of October 24, 2000 and subject to the
     qualifications, assumptions and limitations stated in its written
     opinion of the same date, the Offer Price proposed to be received in the
     Offer and the Merger by the Unaffiliated Stockholders was fair, from a
     financial point of view, to such stockholders. DRW indicated that it was
     willing to confirm this opinion in writing and subsequently did so
     confirm its opinion. See "--Opinion of Financial Advisor to the pcOrder
     Special Committee."

   The pcOrder Board also took into consideration the provisions of the Merger
Agreement, including the lack of prohibitions on responding to subsequent
third-party bidders, the detailed financial information that had been regularly
furnished to the members of the pcOrder Board by pcOrder's senior management
and the general familiarity of each member of the pcOrder Board with the
affairs of pcOrder.

   Based on the foregoing, the pcOrder Board concluded that it was appropriate
to accept the pcOrder Special Committee's recommendation regarding the Merger
Agreement, the Offer and the Merger.

   FOR THE FOREGOING REASONS, ON OCTOBER 24, 2000, THE PCORDER BOARD:

  .  DETERMINED THAT EACH OF THE OFFER AND THE MERGER IS FAIR TO AND IN THE
     BEST INTERESTS OF UNAFFILIATED STOCKHOLDERS;

  .  APPROVED THE MERGER AGREEMENT AND THE TRANSACTIONS IT CONTEMPLATES,
     INCLUDING THE OFFER; AND

  .  RESOLVED TO RECOMMEND THAT PCORDER'S STOCKHOLDERS ACCEPT THE OFFER AND
     TENDER THEIR SHARES IN THE OFFER.

OPINION OF FINANCIAL ADVISOR TO THE PCORDER SPECIAL COMMITTEE

   DRW was retained, pursuant to an engagement letter dated September 25, 2000,
to act as financial advisor to the pcOrder Special Committee and, if requested,
to furnish an opinion as to the fairness, from a financial point of view, of a
proposed transaction.

   Pursuant to the engagement letter and at the request of the pcOrder Special
Committee, DRW delivered to the pcOrder Special Committee on October 24, 2000,
its opinion, as of that date and based on the procedures followed, factors
considered and assumptions made by DRW and subject to certain other
limitations, that the cash consideration proposed to be received by the
Unaffiliated Stockholders in the Offer and the Merger was fair, from a
financial point of view, to such holders. The opinion was subsequently also
delivered to the pcOrder Board.

   The full text of the written opinion of DRW, dated October 24, 2000, which
sets forth the assumptions made, matters considered and limitations on the
review undertaken, is attached as Annex B to this Offer to Purchase and is
incorporated by reference herein. The summary of DRW's opinion is qualified in
its entirety by reference to the full text of such opinion. Holders of Shares
are urged to, and should, read carefully such opinion in its entirety.

   DRW's opinion was provided for the information and assistance of the pcOrder
Special Committee and the pcOrder Board in connection with their evaluation of
the Offer Price. DRW's opinion does not address the relative merits of the
Offer and the Merger and any other transactions or business strategies
discussed by the

                                       20
<PAGE>

pcOrder Special Committee or the pcOrder Board as alternatives to the Offer and
the Merger, or the underlying business decision of the pcOrder Special
Committee and the pcOrder Board to recommend the Offer and the Merger. DRW's
opinion and presentation to the pcOrder Special Committee and the pcOrder Board
were only two of many factors taken into consideration by the pcOrder Special
Committee and the pcOrder Board in making their respective determinations to
approve the Offer and the Merger. DRW's opinion does not constitute a
recommendation to any stockholder as to whether to tender Shares in the Offer
or how such stockholder should vote with respect to the Merger. DRW's opinion
addresses solely the fairness, from a financial point of view, of the
consideration to be paid to the Unaffiliated Stockholders in the Offer and the
Merger and does not address any other term or agreement relating to the Offer
or the Merger, or the ability of Trilogy to finance or otherwise successfully
consummate the Offer and the Merger.

   In rendering its opinion, DRW assumed and relied upon the accuracy and
completeness of the financial, legal, tax, operating and other information
provided by pcOrder and its accountants and legal advisors (including, without
limitation, the financial statements and related notes thereto of pcOrder). DRW
did not assume responsibility for independently verifying and did not
independently verify this information.

   Additionally, DRW was not asked and did not consider the possible effects of
any litigation, other legal claims or any other contingent matters. DRW did not
assume responsibility for and did not perform any independent evaluation or
appraisal of any of the respective assets or liabilities of pcOrder, nor was
DRW furnished with any evaluations or appraisals. DRW did not assume any
obligation to conduct, and did not conduct, any physical inspection of the
property or facilities of pcOrder. DRW's opinion is based on the economic,
market and other conditions as they existed and the information supplied to DRW
as of the date of its opinion. Events occurring after the date of DRW's opinion
may materially affect the assumptions used in preparing the opinion, and DRW
assumes no obligation to update, revise or reaffirm its opinion.

   In connection with arriving at its opinion, DRW:

  .  reviewed and analyzed the financial terms of the October 24, 2000 draft
     of the Merger Agreement;

  .  reviewed and analyzed certain publicly available financial and other
     data with respect to pcOrder and certain other historical relevant
     operating data relating to pcOrder made available to DRW from published
     sources and from the internal records of pcOrder;

  .  conducted discussions with members of the senior management of pcOrder
     with respect to the business prospects and financial outlook of pcOrder;

  .  reviewed the reported prices and trading activity for the Shares;

  .  compared the financial performance of pcOrder and the prices of the
     Shares with that of certain other comparable publicly-traded companies
     and their securities;

  .  reviewed the financial terms, to the extent publicly available, of
     certain comparable transactions;

  .  compared the transaction premium paid to the holders of the Shares to
     the transaction premiums paid in selected transactions where the buyer
     has a controlling interest in a publicly traded company prior to the
     acquisition; and

  .  compared the transaction premium paid to the holders of the Shares to
     the transaction premiums paid in selected transaction of other software
     companies.

   In addition, DRW conducted other such analyses and examinations and
considered such other financial, economic and market criteria as DRW deemed
necessary in arriving at its opinion.

   In delivering its opinion to the pcOrder Special Committee, DRW prepared and
delivered to the pcOrder Special Committee written materials containing various
analyses and other information material to the opinion. The following summaries
of the various analyses and other information include information presented in
tabular format. In order to fully understand the summaries, the tables must be
read together with the text of

                                       21
<PAGE>

each summary. The tables alone do not constitute a complete description of the
analysis or information. A copy of DRW's written presentation to the pcOrder
Special Committee has been filed with the SEC as an exhibit to the Schedule TO
filed by pcOrder and Trilogy in connection with the Offer and will be available
for inspection and copying at the principal executive offices of pcOrder during
regular business hours by any interested stockholder of pcOrder or any
representative of such stockholder who has so designated in writing and also
may be inspected and copied at the office of, and obtained by mail from, the
SEC. See "The Tender Offer -- Section 15. Miscellaneous."

   TRANSACTION CONSIDERATION. Giving effect to the $6.375 per Share Offer Price
and the outstanding Shares, DRW calculated the aggregate equity value of the
offer for the Shares, on a fully diluted basis, to be approximately $45
million. Giving effect to outstanding debt and cash, DRW calculated an
enterprise value (equity value plus debt less cash) for pcOrder in the Offer
and the Merger of approximately $33 million. DRW noted the enterprise value of
pcOrder based on the market closing price on October 24, 2000 to be
approximately negative $21 million.

   TRADING MARKET DATA. DRW reviewed the stock trading history of the Shares.
DRW presented the recent trading information for the Shares contained in the
following table:

<TABLE>
     <S>                                                                  <C>
     Closing price on October 24, 2000................................... $3.44
     30 calendar day moving average......................................  4.08
     60 calendar day moving average......................................  4.68
     90 calendar day moving average......................................  5.71
     52 week high trade.................................................. 74.75
     52 week low trade...................................................  3.06
</TABLE>

   DRW also presented selected price and volume distribution data, presented
pcOrder ownership data and illustrated the relative stock price performance of
pcOrder against the comparable group described below and the Nasdaq Stock
Market.

   PREMIUMS PAID ANALYSIS. DRW reviewed publicly available information for two
groups of selected completed or pending transactions to determine the implied
premium payable in the transactions over recent trading prices.

   For the first group of selected transactions, DRW reviewed publicly
available information for selected completed acquisition transactions
fulfilling the following criteria:

  .  transactions announced in the last two years;

  .  transactions in which the acquiring company owned between 51% and 82.5%
     of the equity of the target immediately prior to the transaction other
     than transactions in select industry groups; and

  .  transactions in which the target company is not in the financial
     industry, heavy industry or food industry.

   DRW performed its analysis on 12 transactions that satisfied these criteria,
and the table below shows a comparison of those premiums to the premium that
would be paid to the Unaffiliated Stockholders based on the Offer Price. The
premium calculations for the Shares are based on an assumed announcement date
of October 24, 2000.

   For the second group of selected transactions, DRW reviewed publicly
available information for selected completed acquisition transactions
fulfilling the following criteria:

  .  transactions announced after January 1, 1999;

  .  transactions in which the target company had revenues greater than $5
     million;

  .  transactions in which the transaction value was between $10 million and
     $500 million; and

  .  transactions involving target companies in the software industry.

   DRW performed its analysis on transactions that satisfied these criteria,
and the table below shows a comparison of those premiums to the premium that
would be paid to the Unaffiliated Stockholders based on the Offer Price. The
premium calculations for the Shares are based on an assumed announcement date
of October 24, 2000.

   PRECEDENT TRANSACTION ANALYSIS. DRW compared the company value of pcOrder
(based on a price per Share equal to the Offer Price) to revenue multiples
relating to the proposed combination of pcOrder and Trilogy with transaction
value to revenue multiples paid in selected acquisitions of software companies
with revenues greater than $5 million that were announced after January 1, 1999
and have transaction values between $10 million and $500 million. For the
purpose of calculating multiples, revenue values were taken as the actual or
estimated revenues of the target companies in the last twelve months prior to
the announcement of the transaction, or LTM revenue. Financial data about the
precedent transactions was taken from SEC filings, press releases and Commscan
M&A Desk.

   The following table presents the company value to revenue multiple for
pcOrder and the low, high, mean and median for the selected comparable
transactions at announcement:

   COMPARABLE COMPANY ANALYSIS. DRW used a comparable company analysis to
analyze pcOrder's implied valuation relative to three groups of publicly traded
companies that DRW deemed for purposes of its analysis to be comparable to
pcOrder. In this analysis, DRW compared the enterprise value of pcOrder (based
on a price per Share equal to the Offer Price), expressed as a multiple of
actual and projected revenue in calendar years 2000 and 2001, to the low, high,
mean and median multiples of enterprise values of comparable companies implied
by the public trading price of their common stock, expressed as a multiple of
the same operating data.

   The comparable companies used by DRW in its analysis came from three groups
of publicly traded companies. The first group contained companies operating in
the software platform industry and included Allaire Corp., NetObjects Inc. and
Viador Inc. The second group contained companies operating in the content
management industry and included Eprise Corporation and Open Market, Inc. The
third group consisted of one company operating in the configuration industry,
which was Calico Commerce, Inc. Although these companies were considered
comparable to pcOrder for the purpose of this analysis based on certain
characteristics of their respective businesses and financial performance, none
of these companies possesses characteristics identical to those of pcOrder.

comparable companies in the calendar years 2000 and 2001:

</TABLE>

   The preparation of a fairness opinion is a complex process that involves the
application of subjective business judgment in determining the most appropriate
and relevant methods of financial analysis and the application of those methods
to the particular circumstances and, therefore, is not necessarily susceptible
to partial consideration of the analyses or summary description. DRW believes
that its analyses must be considered as a whole and that selecting portions of
the analyses and of the factors considered by it, without considering all
factors and analyses, could create an incomplete or misleading view of the
processes underlying its opinion. In arriving at its fairness determination,
DRW considered the results of all of its analyses as well as qualitative
factors, including:

  .  ambiguous technology licenses leading to unclear lines of separation
     between pcOrder and Trilogy over the ownership of products;

  .  the challenges to the marketability of pcOrder to a third party due to
     Trilogy's control of pcOrder, Trilogy's competing business unit and the
     difficulty associated with separating the intellectual property of
     pcOrder and Trilogy;

  .  high employee turnover at pcOrder for several months; and

  .  no new software bookings for the last nine months.

   In view of the wide variety of factors considered in connection with its
evaluation of the fairness, from a financial point of view, of the Offer Price
to the Unaffiliated Stockholders, DRW did not find it practicable to assign
relative weights to the factors considered in reaching its opinion. No single
company or transaction used in the above analyses as a comparison is identical
to pcOrder or the Offer and the Merger. The analyses were prepared solely for
purposes of DRW providing an opinion as to the fairness, from a financial point
of view, to the Unaffiliated Stockholders of the Offer Price and do not purport
to be appraisals or necessarily reflect the prices at which businesses or
securities actually may be sold, which are inherently subject to uncertainty.
In connection with its analyses, DRW made, and was provided by pcOrder's
management with, numerous assumptions with respect to industry performance,
general business and economic conditions and other matters, many of which are
beyond pcOrder's control. Analyses based upon forecasts of future results are
not necessarily indicative of actual future results, which may be significantly
more or less favorable than suggested by such analyses. Because such analyses
are inherently subject to uncertainty, being based upon numerous factors or
events beyond the control of pcOrder or its advisors, none of pcOrder, DRW or
any other person assumes responsibility if future results or actual values are
materially different from these forecasts or assumptions.

   DRW is an internationally recognized investment banking firm and is
regularly engaged in the valuation of businesses and securities in connection
with business combinations and acquisitions, corporate restructurings,
negotiated underwritings, secondary distributions of listed and unlisted
securities, private placements and

                                       24
<PAGE>

valuations for corporate and other purposes. In the ordinary course of
business, DRW and its affiliates may trade securities of pcOrder for their own
account and for the accounts of their customers and, accordingly, may at any
time hold a long or short position in such securities. The pcOrder Special
Committee selected DRW to render its opinion based on DRW's knowledge of the
technology industry, and more specifically the software industry, and its
experience in business combinations and acquisitions and in securities
valuation generally.

   Pursuant to the engagement letter approved by the Special Committee, DRW was
paid a nonrefundable fee of $225,000 by pcOrder upon its engagement and earned
an additional $100,000 as its monthly advisory fee for the approximately one
month period between its engagement and the execution of the Merger Agreement.
In addition, under its engagement letter DRW became entitled, upon the delivery
of its fairness opinion to the pcOrder Special Committee and the pcOrder Board,
to a nonrefundable fee of $500,000 which is not contingent on the completion of
the Offer or the Merger. If the Merger is consummated, DRW will become entitled
to an additional approximately $400,000, representing a contingent transaction
fee equal to 2% of the aggregate value of the transaction (as calculated under
its engagement letter), net of the fairness opinion fee. pcOrder has also
agreed to reimburse DRW for its reasonable out-of-pocket expenses and to
indemnify DRW against certain liabilities relating to or arising out of
services performed by DRW in connection with the business combination. The
terms of the engagement letter, which pcOrder believes are customary for
transactions of this nature, were negotiated at arms'-length between the
pcOrder Special Committee and DRW, and the pcOrder Special Committee was aware
of this fee arrangement at the time of its recommendation of the Merger
Agreement to the pcOrder Board.

POSITION OF TRILOGY REGARDING FAIRNESS OF THE OFFER AND THE MERGER

   Trilogy believes that the consideration to be received by the Unaffiliated
Stockholders pursuant to the Offer and the Merger is fair to and in the best
interests of the Unaffiliated Stockholders. Trilogy bases its belief on the
following factors:

  .  the pcOrder Special Committee, consisting of directors who are neither
     designees of Trilogy nor officers of pcOrder, was appointed to represent
     the interests of the Unaffiliated Stockholders;

  .  the pcOrder Special Committee retained and was advised by independent
     legal counsel and financial advisors;

  .  the Offer and the Merger and the other terms and conditions of the
     Merger Agreement were the result of active arm's-length, good faith
     bargaining between the pcOrder Special Committee and Trilogy and their
     respective advisors;

  .  the pcOrder Special Committee and pcOrder Board each determined that the
     Merger Agreement and the transactions contemplated thereby, including
     the Offer and the Merger, are in the best interests of the Unaffiliated
     Stockholders, approved the Merger Agreement and the transactions
     contemplated thereby, including the Offer and the Merger, and
     recommended that the Unaffiliated Stockholders accept the Offer and
     tender their Shares;

  .  the pcOrder Special Committee and pcOrder Board received an opinion from
     DRW that the $6.375 per Share in cash to be received by the Unaffiliated
     Stockholders in the Offer and the Merger was fair from a financial point
     of view to such stockholders as of October 24, 2000, and subject to the
     assumptions, qualifications and limitations stated in such opinion;

  .  the historical and projected financial performance of pcOrder and its
     financial results;

  .  the analysis of SG Cowen, acting in its capacity as financial advisor to
     Trilogy, described under "--Analysis of Financial Advisor to Trilogy"
     below;

  .  the consideration to be paid in the Offer and the Merger represented a
     premium of approximately 85.5% over the reported last trading price for
     the Shares on the last trading day prior to the public announcement of
     the Offer and the Merger; and

  .  the Offer and Merger will each provide consideration to the stockholders
     entirely in cash.

                                       25
<PAGE>

   Trilogy has reviewed the factors considered by the pcOrder Special Committee
and pcOrder Board in support of their decisions, as described above (See "--
Recommendation of the pcOrder Special Committee and the pcOrder Board; Fairness
of the Offer and the Merger"), and has no basis to question their consideration
of, or reliance on, such factors. Trilogy did not find it practicable to
assign, nor did it assign, relative weights to the individual factors
considered in reaching its conclusion as to fairness.

   The foregoing discussion of the information and factors considered and given
weight by Trilogy is not intended to be exhaustive but is believed to include
all material factors considered by Trilogy.

ANALYSIS OF FINANCIAL ADVISOR TO TRILOGY

   SG Cowen was retained by the Trilogy Special Committee as its financial
advisor to advise Trilogy in connection with its general financial strategy
regarding Trilogy's investment in pcOrder. SG Cowen was not requested to, and
did not, render an opinion with respect to the fairness of the consideration to
be paid pursuant to the Offer. No special instructions were given to SG Cowen
related to its evaluation, and neither Trilogy nor any of its affiliates
imposed any limitations on the scope thereof.

   In a meeting on October 10, 2000 with the Trilogy Special Committee, SG
Cowen made a presentation regarding the proposed transaction (the "Initial SG
Cowen Presentation"). The following is a summary of the Initial SG Cowen
Presentation.

   SG Cowen reviewed certain financial and market statistics relating to
pcOrder, including historical and projected information for pcOrder's revenues,
gross profit, operating income and net income (which historical information was
based on SEC filings and which projected information was provided by pcOrder
management); the market price of the Shares for the period from the date of
pcOrder's initial public offering on February 25, 1999 through October 6, 2000;
and an analysis of the percentage of the Shares traded at specific prices
during the prior three months. SG Cowen then reviewed four separate alternative
strategies with respect to Trilogy's ownership interest in pcOrder. The four
alternatives were (a) maintain the status quo and do nothing, (b) initiate a
restructuring program while keeping pcOrder as a separate entity, (c) acquire
the remaining equity interest in pcOrder, and (d) sell pcOrder to a third
party.

   In a meeting on October 24, 2000 with the Trilogy Board, SG Cowen made a
presentation regarding the proposed Merger Agreement (the "Second SG Cowen
Presentation" and together with the Initial SG Cowen Presentation, the "SG
Cowen Presentations"). The following is a summary of the Second SG Cowen
Presentation.

   SG Cowen reviewed the principal terms of the Merger Agreement, including the
transaction equity value and transaction enterprise value for various
alternative offer prices for the Shares ranging from $3.28 per Share to $6.38
per Share; a comparison of the Offer Price of $6.375 per Share to a range of
historical market prices of the Shares; and the timetable for completing the
Offer and the Merger. SG Cowen then reviewed certain financial and market
statistics relating to pcOrder, including historical and projected information
for pcOrder's revenues, gross profit, operating income and net income (which
historical information was based on SEC filings and which projected information
was provided by pcOrder's management); the market price of the Shares for the
prior twelve months, from the period from July 26, 2000, through October 23,
2000, and for the period from the date of pcOrder's initial public offering on
February 25, 1999 through October 23, 2000; an analysis of the percentage of
the Shares traded at the specific prices during the prior three months, the
prior six months and the prior twelve months; and an analysis of the ownership
of the Shares by institutional investors as of June 30, 2000 and as of
September 30, 1999.

   The summaries set forth above do not purport to be a complete description of
the SG Cowen Presentations. Copies of the SG Cowen Presentations have been
filed as an exhibit to the Schedule 13E-3 on Schedule TO filed by pcOrder and
Trilogy with the SEC. Copies thereof will be made available for inspection and
copying at the principal executive offices of Trilogy during regular business
hours by any interested stockholder of pcOrder, or his or her representative
who has been so designated in writing, and may also be obtained in the manner
described in "The Tender Offer--Section 15. Miscellaneous."

                                       26
<PAGE>

   SG Cowen's analyses were necessarily based on market, industry and other
conditions as in effect on, and the information made available to SG Cowen as
of, the dates of its presentations. Any estimates contained in the analyses
performed by SG Cowen are not necessarily indicative of actual values or actual
future results, which may be significantly more or less favorable than
suggested by such analyses. In addition, analyses relating to the value of
pcOrder do not purport to be appraisals or to reflect the prices at which
pcOrder may actually be sold. Because such estimates are inherently subject to
uncertainty, neither Trilogy nor SG Cowen nor any other person assumes
responsibility for their accuracy.

   As described above, the SG Cowen Presentations were one of many factors
taken into consideration by Trilogy in making its determination to make the
Offer. Consequently, the SG Cowen Presentations should not be viewed as
determinative of Trilogy's decision to enter into the Merger Agreement and make
the Offer.

   In the ordinary course of business, SG Cowen actively trades in securities
of pcOrder for its own account and for the account of its customers and,
accordingly, may at any time hold a long or short position in such securities.

PURPOSE AND STRUCTURE OF THE OFFER AND THE MERGER; REASONS OF TRILOGY FOR THE
OFFER AND THE MERGER

   PURPOSE AND STRUCTURE. The purpose of the Offer is for Trilogy to acquire
the entire equity interest in pcOrder. The purpose of the Merger is for Trilogy
to acquire all of the equity interest in pcOrder not acquired pursuant to the
Offer. Upon consummation of the Merger, pcOrder will become a wholly-owned
subsidiary of Trilogy. The acquisition of the entire equity interest in pcOrder
has been structured as a cash tender offer followed by a cash merger in order
to provide a prompt and orderly transfer of ownership of the equity interest in
pcOrder held by the public stockholders from them to Trilogy and to provide
them with cash for all of their Shares. Neither pcOrder nor Trilogy has made
any provision to grant Unaffiliated Stockholders access to its corporate files
or to obtain counsel or appraisal services at the expense of pcOrder or
Trilogy.

   Under the DGCL, the approval of the pcOrder Board and, under certain
circumstances, the affirmative vote of the holders of a majority of the
outstanding Shares are required to approve and adopt the Merger Agreement and
the transactions contemplated thereby, including the Merger. In the Merger
Agreement, pcOrder has agreed to take all action necessary to convene a special
meeting of its stockholders as promptly as practicable after the consummation
of the Offer for the purpose of considering and taking action on the Merger
Agreement and the transactions contemplated thereby, if such action is required
under the DGCL. Trilogy has agreed that all Shares owned by it and any of its
affiliates will be voted in favor of the Merger Agreement and the transactions
contemplated thereby.

   Under the DGCL, if, following consummation of the Offer, Trilogy owns at
least 90% of the Shares and continues to own at least 90% of the Class B Common
Stock then outstanding, Trilogy will be able to cause the Merger to occur
without a vote of pcOrder's stockholders. In such event, Trilogy and pcOrder
have agreed to take all necessary and appropriate action to cause the Merger to
become effective as soon as reasonably practicable after consummation of the
Offer without a meeting of pcOrder's stockholders. If, following consummation
of the Offer, Trilogy owns less than 90% of the Shares or less than 90% of the
Class B Common Stock then outstanding, a vote of pcOrder's stockholders will be
required under the DGCL to approve the Merger, and a significantly longer
period of time will be required to effect the Merger. See "--The Merger
Agreement--Stockholders' Meeting or Action by Consent." However, in the event
that following consummation of the Offer, Trilogy owns less than 90% of the
Shares then outstanding, Trilogy has agreed to convert such number of shares of
Class B Common Stock into Class A Common Stock to the extent that, after giving
effect to such conversion, Trilogy would own in the aggregate the number of
Shares necessary to be able to cause the merger to occur without a vote of
pcOrder's stockholders.

   REASONS OF TRILOGY FOR THE OFFER AND THE MERGER. Trilogy believes that
significant support from Trilogy would be necessary in order for pcOrder to
survive and continue as a viable stand-alone company. Trilogy views its
acquisition of 100% ownership of pcOrder as the best way to be able to take the
steps necessary in

                                       27
<PAGE>

connection with the business and assets of pcOrder, and the relationship
between pcOrder's assets and personnel and those of Trilogy, so as to maximize
the value of Trilogy's substantial investment in pcOrder. Without Trilogy's
ongoing operational and financial support, pcOrder's ability to survive as an
independent company is questionable, and Trilogy's willingness to continue to
support pcOrder, as it has in the past, with operational support is dependent
upon Trilogy's owning 100% of the equity of pcOrder.

   Trilogy decided to proceed with an acquisition of the entire equity interest
at this time because it believed that the need to remedy pcOrder's continuing
deteriorating financial condition and prospects was immediate from the
perspective of Trilogy's investment in pcOrder. Trilogy was not willing to take
the risks of pursuing a possible sale of pcOrder to a third party because of
the delay that process could entail and associated continuing deterioration of
pcOrder's financial condition and prospects.

   In addition, Trilogy noted that causing pcOrder to be privately-held would
reduce the periodic reports required to be filed with the SEC, would reduce
management's commitment of resources with respect to procedural and compliance
requirements of a public company and would reduce costs associated with
pcOrder's obligations and reporting requirements under the securities laws.

   Trilogy has concluded that the Offer and the Merger, including the $6.375
per Share in cash to be received by the Unaffiliated Stockholders, are fair to
the Unaffiliated Stockholders based upon the factors described above under "--
Position of Trilogy Regarding Fairness of the Offer and the Merger."

PLANS FOR PCORDER AFTER THE OFFER AND THE MERGER; CERTAIN EFFECTS OF THE OFFER

   Pursuant to the Merger Agreement, upon completion of the Offer, Trilogy, Sub
and pcOrder intend to effect the Merger in accordance with the Merger
Agreement. See "--The Merger Agreement."

   Trilogy's management has begun, and intends to continue, a review of pcOrder
and its assets, corporate structure, capitalization, operations, properties,
policies, management and personnel to determine what changes would be desirable
in order best to organize and integrate the activities of pcOrder and Trilogy.
Trilogy expressly reserves the right to make any changes that it deems
necessary or appropriate in light of its review or in light of future
developments or desirable to permit Trilogy to manage pcOrder.

   Except as otherwise disclosed in this Offer to Purchase, Trilogy has no
present plans or proposals that would result in an extraordinary corporate
transaction involving pcOrder or any of its subsidiaries, such as a merger,
reorganization, liquidation, relocation of operations, or sale or transfer of a
material amount of assets. However, efforts are underway to investigate whether
any third party would be interested in acquiring pcOrder's content and
community businesses and consideration is also being given to the possibility
of selling to a third party pcOrder's older enterprise technology and support
of related customer relationships. There is no assurance that any transaction
will result from this investigation. If any transaction is proposed to be
completed before the Merger, whether or not the Offer has been consummated, it
would require the approval of the pcOrder Special Committee and the pcOrder
Board.

   As a result of the Offer, the interest of Trilogy in pcOrder's net book
value and net earnings will increase in proportion to the number of Shares
acquired in the Offer. If the Merger is consummated, Trilogy's interest in such
items and in pcOrder's equity generally will increase to 100%, and Trilogy and
its subsidiaries will be entitled to all benefits resulting from that interest,
including all income generated by pcOrder's operations and any future increase
in pcOrder's value. Similarly, Trilogy will also bear the risk of losses
generated by pcOrder's operations and any decrease in the value of pcOrder
after the Merger. Subsequent to the Merger, the public stockholders will cease
to have any equity interest in pcOrder, will not have the opportunity to
participate in any earnings and growth of pcOrder after the Merger and will not
have any right to vote on corporate matters. Similarly, stockholders will not
face the risk of losses generated by pcOrder's operations or decline in the
value of pcOrder after the Merger.

                                       28
<PAGE>

   The Shares are currently traded on Nasdaq's National Market System. See "The
Tender Offer--Section 6. Price Range of Shares." Following the consummation of
the Merger, the Shares will no longer be quoted on the Nasdaq National Market
System. In addition, the registration of the Shares under the Exchange Act is
expected to be terminated upon application by pcOrder to the SEC if there are
fewer than 300 record holders of the Shares. Accordingly, after the Merger
there will be no publicly traded equity securities of pcOrder outstanding, and
pcOrder will no longer be required to file periodic reports with the SEC. See
"The Tender Offer--Section 11. Certain Effects of the Offer on the Market for
the Shares."

THE MERGER AGREEMENT

   The following is a summary of material provisions of the Merger Agreement,
which is attached as Annex A to this Offer to Purchase. This summary is not a
complete description and is qualified in its entirety by reference to the
Merger Agreement. Capitalized terms not otherwise defined in the following
description shall have the meanings ascribed to them in the Merger Agreement.

   THE OFFER. The Offer is being made pursuant to the provisions of the Merger
Agreement. Following the satisfaction or waiver of the conditions to the Offer,
Trilogy is required by the Merger Agreement to accept for payment, in
accordance with the terms of the Offer, all Shares which have been validly
tendered and not withdrawn pursuant to the Offer as soon as it is permitted to
do so pursuant to applicable law. The only conditions to Trilogy's obligation
to make the Offer and to accept for payment and to pay for any Shares tendered
pursuant to the Offer are the conditions set forth in Annex A to the Merger
Agreement, which are also contained in "The Tender Offer--Section 13. Certain
Conditions to the Offer."

   Although Trilogy has expressly reserved the right to amend or make changes
to the terms and conditions of the Offer, the Merger Agreement provides that,
without the written consent of pcOrder (expressed in a resolution adopted by
both the pcOrder Special Committee and the pcOrder Board), Trilogy shall not
(i) decrease the Offer Price or change the form of consideration to be paid in
the Offer, (ii) impose any additional conditions to the Offer from those set
forth in Annex A to the Merger Agreement, (iii) reduce the number of Shares
subject to the Offer, or (iv) otherwise amend the Offer in a manner that would
adversely affect the holders of Shares.

   Notwithstanding anything in the Merger Agreement to the contrary, without
the prior consent of pcOrder, Trilogy has the right to extend the Offer beyond
the Initial Expiration Date in the following events: (i) from time to time if,
at the Initial Expiration Date (or extended expiration date of the Offer, if
applicable), any of the conditions to the Offer shall not have been satisfied
or waived; (ii) for any period required by any rule, regulation,
interpretation, or position of the SEC or the staff thereof applicable to the
Offer or any period required by applicable law; or (iii) pursuant to an
amendment to the Offer providing for a subsequent offering period not to exceed
twenty business days to the extent permitted under, and in compliance with,
Rule 14d-11 under the Exchange Act. However, as a condition to Trilogy's right
to extend the Offer pursuant to the preceding clause (iii), Trilogy must waive,
with respect to all Shares validly tendered during the subsequent offering
period referred to in said clause (iii), all conditions of the Offer. In
addition, if at any scheduled expiration date of the Offer any of the
conditions of the Offer have not been satisfied or waived by Trilogy but are
reasonably capable of being satisfied, Trilogy must extend the Offer for ten
calendar days from the then-scheduled expiration date of the Offer; provided
that Trilogy is not obligated to extend the Offer pursuant to this sentence
more than once.

   THE MERGER. The Merger Agreement provides that, promptly following
consummation of the Offer, Trilogy will contribute all of the Shares purchased
by Trilogy in the Offer and all Class B Common Stock to Sub if necessary to
effect the Merger as a Short-Form Merger. Sub will then be merged with and into
pcOrder in accordance with the applicable provisions of the DGCL as soon as
practicable after the satisfaction or waiver of the conditions to the Merger
set forth in the Merger Agreement. Following the Merger, pcOrder will be the
surviving corporation (the "Surviving Corporation"), and the separate corporate
existence of Sub shall cease.

                                       29
<PAGE>

At the Effective Time, by virtue of the Merger and without any action on the
part of any holder of Shares, (i) each share of Class A Common Stock and Class
B Common Stock issued and outstanding immediately prior to the Effective Time
(other than (x) Shares held in pcOrder's treasury or owned by Trilogy or Sub
(all of which will be cancelled), and (y) Dissenting Shares) will be converted
into and represent the right to receive an amount in cash per Share equal to
the Offer Price (the "Merger Consideration"), and (ii) each share of Sub Common
Stock issued and outstanding immediately prior to the Effective Time will be
converted into one share of the Surviving Corporation Common Stock.

   CERTIFICATE OF INCORPORATION AND BYLAWS. The Merger Agreement also provides
that at the Effective Time, the Certificate of Incorporation of pcOrder in
effect immediately prior thereto shall remain the Certificate of Incorporation
of the Surviving Corporation until amended in accordance with applicable law;
and the Bylaws of pcOrder in effect immediately prior thereto shall be amended
and restated in their entirety to read identically with the Bylaws of Sub as
then in effect, except that the Bylaws shall retain pcOrder's current name.

   DIRECTORS AND OFFICERS OF THE SURVIVING CORPORATION. The Merger Agreement
provides that the directors of Sub immediately prior to the Effective Time (who
will be designees of Trilogy) shall be the initial directors of the Surviving
Corporation until their respective successors are duly elected or appointed and
qualified in the manner provided in the Certificate of Incorporation and Bylaws
of the Surviving Corporation. The officers of Sub immediately prior to the
Effective Time shall be the initial officers of the Surviving Corporation until
their respective successors are duly elected or appointed and qualified in the
manner provided in the Certificate of Incorporation and Bylaws of the Surviving
Corporation.

   TREATMENT OF OPTIONS AND ESPP. The Merger Agreement provides that pcOrder
shall use commercially reasonable efforts to cause all holders of options to
purchase Class A Common Stock granted under pcOrder's 1996 Stock Option Plan
and 1999 Stock Incentive Plan, each as amended (collectively, the "Stock Option
Plans"), to execute prior to the Effective Time an Option Relinquishment and
Release Agreement. As soon as practicable after the Effective Time, Trilogy and
the Surviving Corporation shall cause to be paid to such holders who have
previously delivered an Option Relinquishment and Release Agreement a cash
amount equal to the product of (i) the number of shares of Class A Common Stock
subject to such option (irrespective of whether such option is then
exercisable) and (ii) the amount by which the Merger Consideration exceeds the
exercise or strike price per share of Class A Common Stock subject to such
option immediately prior to the Effective Time, less any required withholding
taxes.

   In the event that an option holder fails to deliver an Option Relinquishment
and Release Agreement prior to the Effective Time and remains employed by
pcOrder at all times through and including the Effective Time, such holder's
options (the "Outstanding Options") shall, in accordance with the terms and
conditions of the governing Stock Option Plan and the holder's stock option
agreement(s), be converted without any action on the part of the holder thereof
into the right to receive an amount equal to the Merger Consideration, upon the
exercise of such holder's options in accordance with, and within the time
prescribed by, the applicable Stock Option Plan and the holder's stock option
agreement(s). In the event that an option holder voluntarily terminates such
option holder's employment with pcOrder prior to the Effective Time, whether or
not such option holder has executed an Option Relinquishment and Release
Agreement, such option holder's options shall be treated, in connection with
the consummation of the Merger, in accordance with the applicable Stock Option
Plan without regard to the provisions in this paragraph.

   pcOrder has also agreed to use commercially reasonable efforts to cause all
holders of options to purchase Class A Common Stock granted under pcOrder's
2000 Nonstatutory Stock Option Plan (the "2000 Plan") to execute prior to the
Effective Time an Option Relinquishment and Release Agreement. As soon as
practicable after the Effective Time, Trilogy and the Surviving Corporation
shall cause the Paying Agent to pay to such holders who have previously
delivered an Option Relinquishment and Release Agreement a cash amount equal to
the product of (i) the number of shares of Class A Common Stock subject to such
option (irrespective of whether such option is then exercisable) and (ii) the
amount by which the Merger Consideration exceeds the exercise or strike price
per share of Class A Common Stock subject to such option immediately prior to
the

                                       30
<PAGE>

Effective Time, less any required withholding taxes. In the event that an
option holder voluntarily terminates such option holder's employment with
pcOrder prior to the Effective Time, such option holder's options shall be
treated, in connection with the consummation of the Merger, in accordance with
the provisions of the applicable 2000 Plan without regard to the provisions in
this paragraph. In the event that an option holder fails to deliver an Option
Relinquishment and Release Agreement prior to the Effective Time, such holder's
rights shall be controlled by the terms of the 2000 Plan.

   As reflected in the Merger Agreement, the pcOrder Board has terminated,
effective as of November 1, 2000, pcOrder's Employee Stock Purchase Plans
(collectively, the "ESPP").

   MERGER WITHOUT STOCKHOLDERS' MEETING. If Trilogy owns in the aggregate at
least 90% of the outstanding Shares as a result of the purchase of Shares
pursuant to the Offer and continues to hold at least 90% of the outstanding
Class B Common Stock, Trilogy and pcOrder have agreed to take all necessary and
appropriate action to cause the Merger to become effective as soon as
practicable after the satisfaction or waiver of the conditions to the Merger
set forth in the Merger Agreement without a meeting or vote of stockholders of
pcOrder as a Short-Form Merger, in accordance with Section 253 of the DGCL.
However, if following the purchase of Shares pursuant to the Offer, Trilogy
owns in the aggregate less than 90% of the outstanding Shares, Trilogy has
agreed to convert such number of shares of Class B Common Stock into Class A
Common Stock to the extent that, after giving effect to such conversion,
Trilogy will own in the aggregate the number of Shares necessary to effect the
Merger as a Short-Form Merger.

   STOCKHOLDERS' MEETING OR ACTION BY CONSENT. pcOrder has agreed in the Merger
Agreement that, if required by applicable law, pcOrder acting through the
pcOrder Board will (i) duly call, give notice of, convene and hold a special
meeting of stockholders as soon as practicable following the acceptance for
payment and purchase of Shares by Trilogy pursuant to the Offer to consider and
vote upon the approval and adoption of the Merger Agreement and the Merger,
(ii) prepare and file with the SEC a preliminary proxy statement or information
statement, as appropriate, relating to the Merger Agreement and the Merger, and
(iii) include in the proxy statement the recommendations of the pcOrder Special
Committee and the pcOrder Board that the stockholders of pcOrder vote in favor
of the approval and adoption of the Merger Agreement and the Merger, except to
the extent that the pcOrder Board, based on the recommendation of the pcOrder
Special Committee, shall have determined in good faith, having received (in the
case of the pcOrder Special Committee) the advice of its outside counsel, that
such recommendation would violate its fiduciary duties under applicable law.

   In addition, the Merger Agreement provides that Trilogy will vote all of its
shares of Sub Common Stock in favor of the approval and adoption of the Merger
Agreement and the Merger, if necessary to effect the Merger. Also, if a vote of
stockholders of pcOrder is necessary to effect the Merger, Trilogy will vote or
cause to be voted, all shares of pcOrder Class A and Class B Common Stock owned
by it and its subsidiaries in favor of the approval and adoption of the Merger
Agreement and the Merger.

   If the Merger cannot be effected without stockholder approval as a Short-
Form Merger, Trilogy may elect (in lieu of pcOrder submitting the Merger
Agreement and the Merger to a vote of its stockholders at a special meeting) to
execute a written consent approving and adopting the Merger Agreement and the
Merger, consistent with the applicable requirements of Delaware law and the
federal securities laws.

   INTERIM OPERATIONS. pcOrder has agreed that, prior to the Effective Time,
unless Trilogy (acting through any of its executive officers) shall otherwise
agree in writing (see "Plans for pcOrder After the Offer and the Merger;
Certain Effects of the Offer") or except as otherwise expressly contemplated by
the Merger Agreement: (i) the business of pcOrder shall be conducted only in,
and pcOrder shall not take any action except in, the ordinary and usual course
of business consistent with past practice; (ii) pcOrder shall cooperate with
Trilogy to implement mutually acceptable measures intended to keep available
the services of its officers and key employees and to preserve the good will of
those having business relationships with any of them; and (iii) pcOrder shall
not, directly or indirectly:

                                       31
<PAGE>

  . declare or pay any dividend or make any distribution with respect to any
    shares of its capital stock;

  . purchase or otherwise acquire or propose to purchase or otherwise
    acquire, any outstanding share of its capital stock;

  . propose or adopt any amendments to its Certificate of Incorporation or
    Bylaws;

  . issue, sell, pledge, dispose of or encumber any capital stock of pcOrder,
    except to allow Trilogy to convert Class B Common Stock into Class A
    Common Stock, as contemplated by the Merger Agreement, the exercise of
    stock options outstanding on October 20, 2000 or pursuant to the terms of
    the ESPP as in effect on October 25, 2000;

  . except in the ordinary and usual course of business and consistent with
    past practice, sell, pledge, dispose of or encumber any of its material
    assets;

  . incur any long-term indebtedness for borrowed money, issue any debt
    securities or assume, guarantee or endorse any material obligations of
    any other person;

  . approve, adopt or amend any agreement, plan, program or arrangement that
    provides any benefits to any employee of pcOrder (other than as
    contemplated by the Merger Agreement);

  . except in the ordinary and usual course of business consistent with past
    practice, increase, directly or indirectly, the compensation of any
    employee of pcOrder;

  . acquire or agree to acquire by merging or consolidating with, or by
    purchasing a substantial portion of the stock or assets of, or by any
    other manner, any business or any person;

  . take any action to materially reduce the number of pcOrder's employees;

  . enter into any material lease or license or otherwise subject to any
    material lien any of pcOrder's properties or assets;

  . modify, amend in any material respect or terminate any of pcOrder's
    material contracts;

  . waive, release or assign any rights that are material to pcOrder;

  . permit any insurance policy naming pcOrder as a beneficiary or loss
    payable payee to lapse, be cancelled or expire unless a new policy with
    substantially identical coverage is in effect as of the date of such
    lapse, cancellation or expiration; or

  . authorize any of the foregoing, or enter into any contract, agreement,
    commitment or arrangement to do any of the foregoing.

   ACCESS TO INFORMATION. The Merger Agreement provides that pcOrder shall
afford to Trilogy, Sub and their representatives such access during normal
business hours throughout the period prior to the Effective Time to pcOrder's
books, records (including without limitation, tax return and work papers of
pcOrder's independent auditors), facilities, personnel and to such other
information as Trilogy shall reasonably request. In addition, the Merger
Agreement provides that all such information shall, to the fullest extent
consistent with applicable law, be subject to the provisions of a
confidentiality agreement between pcOrder and Trilogy entered into on September
28, 2000.

   COMMERCIALLY REASONABLE EFFORTS. pcOrder, Trilogy and Sub have each agreed
in the Merger Agreement, subject to the terms and conditions thereof, to use
their commercially reasonable efforts to take, or cause to be taken, all
actions and to do, or cause to be done, all things necessary, proper or
advisable to consummate and make effective as promptly as practicable the
Offer, the Merger and the other transactions contemplated by the Merger
Agreement, and to cooperate with each other in connection with the foregoing,
including using their reasonable best efforts to (i) obtain all necessary
waivers, consents and approvals from other parties to material agreements,
leases and other contracts, (ii) obtain all necessary consents, approvals and
authorizations as are required to be obtained under any federal, state or
foreign law or regulation, (iii) lift or rescind any injunction or restraining
order or other order adversely affecting the ability of the parties to
consummate the transactions contemplated by the Merger Agreement, (iv) effect
any necessary registrations and filings and submissions of

                                       32
<PAGE>

information requested by governmental authorities, and (v) fulfill all
conditions to the Merger Agreement. In addition, pcOrder will permit Trilogy to
reasonably participate in the defense and settlement of any claim, suit or
cause relating to the Offer, the Merger or the other transactions contemplated
by the Merger Agreement, and pcOrder shall not settle or compromise any such
claim, suit or cause of action without Trilogy's prior written consent, which
shall not be unreasonably withheld.

   NOTIFICATION OF THIRD PARTY OFFERS. Trilogy and pcOrder have agreed that
pcOrder will promptly notify Trilogy if pcOrder, any of its affiliates, any of
its officers, directors, employees, agents or representatives (including
without limitation its financial advisors, attorneys and accountants), (i)
initiates contact with, (ii) enters into or participates in any discussions or
negotiations with, (iii) discloses, directly or indirectly, any information not
customarily disclosed concerning the business and properties of pcOrder to, or
(iv) affords any access to pcOrder's properties, books and records to any
corporation, partnership, person or other entity or group in connection with
any possible proposal relating to (a) the disposition of pcOrder's business or
assets, (b) the acquisition or disposition of any equity securities of pcOrder,
(c) the merger of pcOrder with any person other than Sub, or (d) any similar
transaction, except as contemplated by the Merger Agreement. Further, pcOrder
will promptly notify Trilogy orally of all of the relevant details of any
inquiry or proposal that it receives relating to any such matters.

   ROLE OF PCORDER SPECIAL COMMITTEE. Prior to the earlier to occur of the
Effective Time or the termination of the Merger Agreement pursuant to its
terms: (i) Trilogy shall not take, or cause to be taken, any action to remove
from office, or impair the authority of, any member of the pcOrder Special
Committee; and (ii) without limiting the effect of any other provision of the
Merger Agreement that confers authority upon the pcOrder Special Committee with
respect to the Merger Agreement, all of the rights of pcOrder under the Merger
Agreement (including, without limitation, rights of waiver and enforcement)
are, to the fullest extent permitted by the DGCL, vested exclusively in the
pcOrder Special Committee and shall be exercised by pcOrder only with the
consent, or at the express direction, of the pcOrder Special Committee.

   INDEMNIFICATION AND INSURANCE. Trilogy and pcOrder have agreed that all
rights to indemnification and advancement of expenses now existing in favor of
the present or former directors or officers of pcOrder as provided in pcOrder's
Certificate of Incorporation and Bylaws, in effect as of the date of the Merger
Agreement, with respect to matters occurring prior to the Effective Time, shall
survive the Merger and continue in full force and effect after the Effective
Time. To the maximum extent permitted by law, such indemnification will be
mandatory rather than permissive, and pcOrder or the Surviving Corporation, as
the case may be, have agreed to advance expenses in connection with such
indemnification. Trilogy and pcOrder have further agreed that all rights to
indemnification now existing in favor of the present or former directors or
officers of pcOrder in any indemnification agreement between such person and
pcOrder shall survive the Merger and continue in full force and effect in
accordance with the terms of such agreement.

   Trilogy or the Surviving Corporation shall maintain in effect for six years
from the Effective Time, to the extent available, the current directors' and
officers' liability insurance policies maintained by Trilogy or pcOrder
covering those directors and officers of pcOrder who are currently covered by
such policies with respect to matters occurring prior to the Effective Time;
provided, however, that: (i) Trilogy or the Surviving Corporation may
substitute therefor policies of at least the same coverage containing terms and
conditions that are not less favorable to the beneficiaries thereof, so long as
such substitution does not result in gaps or lapses in coverage; (ii) in no
event shall Trilogy or the Surviving Corporation be required to expend in any
one year an amount in excess of 150% of the annual premiums currently paid by
pcOrder for such insurance (in which event Trilogy or the Surviving Corporation
shall cause to be maintained directors' and officers' liability insurance that,
in Trilogy's good faith judgment, provides the maximum coverage available for
such maximum premium and reasonably comparable to the current coverage); and
(iii) Trilogy may meet its obligations under this paragraph by covering the
above persons under Trilogy's insurance policy or policies on the terms
described above.

                                       33
<PAGE>

   In the event that Trilogy or the Surviving Corporation or any of its
successors or assigns (i) consolidates with or merges into any other person and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger or (ii) transfers or conveys all or any substantial
portion of its properties and assets to any person, then, and in each such
case, proper provision will be made so that the successors and assigns of such
party assume the indemnification obligations of such party as contemplated by
two immediately preceding paragraphs.

   REPRESENTATIONS AND WARRANTIES. The Merger Agreement contains various
customary representations and warranties of the parties thereto including,
among others, representations as to due organization and existence,
capitalization, corporate authority, lack of a violation of the Certificate of
Incorporation or Bylaws, debt instruments or material agreements of pcOrder or
applicable law resulting from the Offer and the Merger, accuracy of pcOrder's
public filings, including financial statements, absence of any material adverse
change in pcOrder's business, absence of undisclosed liabilities, and the
accuracy of information included in certain materials in connection with the
transactions contemplated by the Merger Agreement.

   In the Merger Agreement, Trilogy has represented and warranted that it has
the funds necessary to complete the transactions contemplated by the Merger
Agreement. Trilogy has also represented and warranted that if it borrows any
funds to finance any of those transactions, none of the borrowings will be
incurred by, or secured (directly or indirectly) by the assets of, pcOrder.

   CONDITIONS TO THE MERGER. The Merger Agreement provides that the respective
obligations of Trilogy, Sub and pcOrder to consummate the Merger are subject to
the satisfaction or waiver at or prior to the Effective Time of each of the
following conditions: (i) the Merger Agreement and the Merger shall have been
approved and adopted by the requisite vote of the stockholders of pcOrder, if
required by applicable law in order to consummate the Merger; (ii) no
governmental entity or federal or state court of competent jurisdiction shall
have enacted, issued, promulgated, enforced or entered any statute, rule,
regulation, executive order, decree, injunction or other order (whether
temporary, preliminary or permanent) that is in effect and that materially
restricts, prevents or prohibits consummation of the Merger or the other
transactions contemplated by the Merger Agreement; provided, however, that the
parties shall use their reasonable best efforts to cause any such decree,
judgment, injunction or other order to be vacated or lifted; and (iii) Trilogy
shall have purchased Shares pursuant to the Offer.

   TERMINATION; FEES AND EXPENSES. The Merger Agreement may be terminated and
the transactions contemplated by the Merger Agreement may be abandoned at any
time prior to the Effective Time, whether prior to or after approval by the
stockholders of pcOrder:

  . by mutual written consent of the pcOrder Board (as agreed to by the
    pcOrder Special Committee) and the Boards of Directors of Trilogy and
    Sub; or

  . by either Trilogy or pcOrder (acting through the pcOrder Special
    Committee) if (i) Trilogy shall not have purchased any Shares pursuant to
    the Offer on or before January 31, 2001; provided, however, that this
    right to terminate the Merger Agreement will not be available to any
    party whose failure to fulfill any obligation under the Merger Agreement
    has been the cause of, or resulted in, the failure of the Offer to be
    consummated on or before such date, or (ii) any court of competent
    jurisdiction or other governmental entity shall have issued an order,
    decree, ruling or taken any other action restraining, enjoining or
    otherwise prohibiting the Merger and such order, decree, ruling or other
    action shall have become final and nonappealable; or

  . by Trilogy and Sub if, prior to the purchase of Shares pursuant to the
    Offer, the pcOrder Special Committee or the pcOrder Board shall have
    (including by amendment to the Schedule 14D-9) withdrawn or modified in a
    manner adverse to Trilogy its approval or recommendation of the Offer,
    the Merger or the Merger Agreement or shall have resolved to do any of
    the foregoing; or

                                       34
<PAGE>

  . by pcOrder (acting through the pcOrder Special Committee) if due to an
    occurrence or circumstance, not involving a breach by pcOrder of its
    obligations thereunder, which would result in a failure to satisfy any of
    the conditions to the Offer (see "The Tender Offer--Section 13. Certain
    Conditions to the Offer") or otherwise contained in the Merger Agreement,
    Trilogy shall have terminated the Offer or permitted the Offer to expire
    without the purchase of Shares thereunder or prior to the purchase of any
    Shares pursuant to the Offer, either (i) Trilogy materially breaches or
    fails in any material respect to perform or comply with any of its
    material covenants and the agreements contained in the Merger Agreement,
    or (ii) Trilogy breaches in any material respect any of its
    representations and warranties granted in the Merger Agreement, and, in
    either case, a Trilogy Material Adverse Effect results therefrom; or

  . by pcOrder (acting through the pcOrder Special Committee) if, in
    exercising its business judgment after consultation with its independent
    legal and financial advisors and taking into account their advice, it
    determines that a competing offer is superior to the Offer; provided,
    however, that in such event pcOrder will pay to Trilogy the sum of $1.25
    million within two business days after acceptance of the competing offer,
    which sum will constitute reimbursement to Trilogy for all of its
    expenses incurred in connection with the Merger Agreement; provided
    first, however, that pcOrder shall have materially complied with its
    obligations to provide Trilogy the notice described under "--Notification
    of Third Party Offers," above.

   In the event of the termination of the Merger Agreement as provided above,
except as provided in the next paragraph regarding fees and expenses, the
Merger Agreement shall become void and have no effect, and there shall be no
liability on the part of Trilogy, Sub or pcOrder. However, a termination shall
not relieve any party from liability for any willful breach of the Merger
Agreement.

   Except for the possible payment of $1.25 million to Trilogy by pcOrder for
the acceptance of a competing offer as described above, all costs and expenses
incurred in connection with the Offer, the Merger, the Merger Agreement and the
consummation of the transactions contemplated by the Merger Agreement shall be
paid by the party incurring such expenses, regardless of whether the Offer or
the Merger shall be consummated.

   AMENDMENTS; WAIVERS. The Merger Agreement may not be amended except pursuant
to an instrument in writing signed by pcOrder following approval of such action
by the pcOrder Special Committee and signed by Trilogy and Sub; provided,
however, that after any approval of the Merger Agreement by the stockholders of
pcOrder, no amendment may be made without the further approval of the
stockholders of pcOrder which amendment would: (i) decrease the Merger
Consideration; (ii) change any other terms and conditions of the Merger
Agreement if any of the changes would, individually or in the aggregate,
materially adversely affect the stockholders of pcOrder; or (iii) otherwise
require stockholder approval under the DGCL.

   At any time prior to the Effective Time, whether before or after approval of
the Merger Agreement by the stockholders of pcOrder, Trilogy, Sub or pcOrder,
by action taken by the pcOrder Special Committee on behalf of pcOrder or by
Trilogy and Sub, as the case may be, may (a) extend the time for the
performance of any of the obligations or other acts of any other party to the
Merger Agreement, (b) waive any inaccuracies in the representations and
warranties contained in the Merger Agreement or in any document, certificate or
writing delivered pursuant to the Merger Agreement, or (c) waive compliance
with any of the agreements of any other party or with any conditions to its own
obligations. Any agreement on the part of a party to the Merger Agreement to
any such extension or waiver shall be valid only if set forth in an instrument
in writing signed on behalf of such party by a duly authorized officer.

DISSENTERS' RIGHTS

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

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

   If the Merger is consummated, stockholders of pcOrder who have not sold
their Shares will have certain rights under the DGCL to dissent and demand
appraisal of, and to receive payment in cash of the fair value of, their
Shares. Under Section 262 of the DGCL, any holder of Shares at the Effective
Time (a "Remaining Stockholder") who does not wish to accept the Merger
Consideration pursuant to the Merger has the right to seek an appraisal and be
paid the "fair value" of such holder's Shares at the Effective Time (exclusive
of any element of value arising from the accomplishment or expectation of the
Merger) judicially determined and paid to it in cash, provided that such holder
complies with the provisions of such Section 262 of the DGCL.

   The following is a brief summary of the statutory procedures to be followed
by a Remaining Stockholder in order to dissent from the Merger and perfect
appraisal rights under Delaware law. This summary is not intended to be
complete and is qualified in its entirety by reference to Section 262 of the
DGCL, the text of which is set forth in Annex C hereto. Any Remaining
Stockholder considering demanding appraisal is advised to consult legal
counsel. Dissenters' rights will not be available unless and until the Merger
is consummated.

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

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

   A record owner, such as a broker, who holds Shares as a nominee for others,
may exercise appraisal rights with respect to the Shares held for all or less
than all beneficial owners of Shares as to which the holder is the record
owner. In such case the written demand must set forth the number of Shares
covered by such demand.

                                       36
<PAGE>

Where the number of Shares is not expressly stated, the demand will be presumed
to cover all Shares outstanding in the name of such record owner. Beneficial
owners who are not record owners and who intend to exercise appraisal rights
should instruct the record owner to comply strictly with the statutory
requirements with respect to the exercise of appraisal rights before the date
of any meeting of stockholders of pcOrder called to approve the Merger, in the
case of a long-form merger, and within 20 days following the mailing of the
Notice of Merger, in the case of a Short-Form Merger.

   Remaining Stockholders who elect to exercise appraisal rights must mail or
deliver their written demands to: Secretary, pcOrder.com, Inc., 5001 Plaza on
the Lake, Austin, Texas 78746. The written demand must reasonably inform
pcOrder of the identity of the stockholder and that the stockholder thereby
intends to demand appraisal. In the case of a long-form merger, pcOrder must,
within ten days after the Effective Time, provide notice of the Effective Time
to all stockholders who have complied with Section 262 of the DGCL and have not
voted for approval and adoption of the Merger Agreement.

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

   Regardless of whether the Merger is effected as a long-form merger or a
Short-Form Merger, within 120 days after the Effective Time, either pcOrder or
any stockholder who has complied with the required conditions of Section 262
and who is otherwise entitled to appraisal rights may file a petition in the
Delaware Court of Chancery demanding a determination of the fair value of the
Shares of the dissenting stockholders. If a petition for an appraisal is timely
filed, after a hearing on such petition, the Delaware Court of Chancery will
determine which stockholders are entitled to appraisal rights and thereafter
will appraise the Shares owned by such stockholders, determining the fair value
of such Shares, exclusive of any element of value arising from the
accomplishment or expectation of the Merger, together with a fair rate of
interest to be paid, if any, upon the amount determined to be the fair value.
In determining fair value, the Delaware Court of Chancery is to take into
account all relevant factors. Accordingly, such determination could be based
upon considerations other than, or in addition to, the market value of the
Shares. In Weinberger v. UOP, Inc., et al., the Delaware Supreme Court
discussed the factors that could be considered in determining fair value in an
appraisal proceeding, stating that "proof of value by any techniques or methods
which are generally considered acceptable in the financial community and
otherwise admissible in court" should be considered in appraisal proceedings.
The Delaware Supreme Court stated that in making this determination of fair
value the court must consider "market value, asset value, dividends, earnings
prospects, the nature of the enterprise and any other facts which were known or
which could be ascertained as of the date of merger which throw any light on
future prospects of the merged corporation...." The Delaware Supreme Court has
construed Section 262 of the DGCL to mean that "elements of future value,
including the nature of the enterprise, which are known or susceptible of proof
as of the date of the merger and not the product of speculation, may be
considered." However, the court noted that Section 262 provides that fair value
is to be determined "exclusive of any element of value arising from the
accomplishment or expectation of the merger."

   Remaining Stockholders who in the future consider seeking appraisal should
have in mind that the fair value of their Shares determined under Section 262
could be more than, the same as, or less than the Merger Consideration if they
do seek appraisal of their Shares, and that opinions of investment banking
firms as to fairness from a financial point of view are not necessarily
opinions as to fair value under Section 262 of the DGCL. Moreover, Trilogy
intends to cause the Surviving Corporation to argue in any appraisal proceeding
that, for purposes thereof, the "fair value" of the Shares is less than that
paid in the Offer.

                                       37
<PAGE>

   The cost of the appraisal proceeding may be determined by the Delaware Court
of Chancery and taxed upon the parties as the Delaware Court of Chancery deems
equitable in the circumstances. Upon application of a dissenting stockholder,
the Delaware Court of Chancery may order that all or a portion of the expenses
incurred by any dissenting stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorneys' fees and the
fees and expenses of experts, be charged pro rata against the value of all
Shares entitled to appraisal. In the absence of such a determination or
assessment, each party bears its own expenses.

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

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

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

   Several decisions by Delaware courts have held that, in certain
circumstances, a controlling stockholder of a company involved in a merger has
a fiduciary duty to other stockholders that requires that the merger be
"entirely fair" to such other stockholders. In determining whether a merger is
fair to minority stockholders, Delaware courts have considered, among other
things, the type and amount of consideration to be received by the stockholders
and whether there was fair dealing among the parties. The Delaware Supreme
Court stated in Weinberger and in Rabkin v. Philip A. Hunt Chemical Corp. that
although the remedy ordinarily available to minority stockholders is the right
to appraisal described above, monetary damages, injunctive relief or such other
relief as the court may fashion may be available if a merger is found to be the
product of procedural unfairness, including fraud, misrepresentation or other
misconduct.

 * Less than 1% of the Shares.

(1) For purposes of calculating the percentage beneficially owned by Trilogy,
    Inc. and Mr. Liemandt, the 10,316,620 shares of Class B Common Stock
    beneficially owned by Trilogy, Inc. have been assumed converted into shares
    of Class A Common Stock. Percentage of beneficial ownership for Trilogy,
    Inc., and Mr. Liemandt (but not for any of the other listed beneficial
    owners) is based upon 16,554,185 aggregate shares of Class A Common Stock
    and Class B Common Stock outstanding. Trilogy, Inc. is the parent of
    Trilogy. The shares of Class B Common Stock owned by Trilogy, Inc. are
    registered in the name of Trilogy. Because these shares of Class B Common
    Stock are already beneficially owned by Trilogy, the Shares into which they
    are convertible will not be purchased in the Offer. Of the Shares
    beneficially owned by Trilogy, Inc., 20,620 are subject to options granted
    by Trilogy to certain of its employees, entitling these employees to
    purchase the Shares at any time prior to August 25, 2009, at a price of
    $5.00 per Share. Through his ownership of securities of Trilogy, Inc.,
    Mr. Liemandt has the right to cause to be elected a majority of the Trilogy
    Board. As a result, Mr. Liemandt may, under the rules of the SEC, be deemed
    to be the beneficial owner of the Shares beneficially owned by Trilogy,
    Inc. Mr. Liemandt disclaims beneficial ownership of the Shares beneficially
    owned by Trilogy, Inc., except with respect to any proportional pecuniary
    interest therein.

(2) In computing the number of Shares beneficially owned by a person and the
    percentage ownership of that person, Shares subject to options held by that
    person that are currently exercisable within 60 days of October 31, 2000,
    are included as Shares beneficially owned. The Shares issuable pursuant to
    these options are deemed outstanding for purposes of computing the
    percentage ownership of the person holding

                                       39
<PAGE>

   the options but are not deemed outstanding for purposes of computing the
   percentage ownership of any other person. Options included in beneficial
   ownership for the following individuals are as follows: Mr. Liemandt, 100
   Shares; Mr. Barris, 5,000 Shares; Mr. Lacy, 12,500 Shares; Mr. Stearns,
   12,500 Shares; Mr. Cooley, 445,000 Shares; Ms. Jones,640,100 Shares; Mr.
   Friedman, 18,750 Shares; Mr. Thompson, 10,106 Shares; Mr. Agarwal, 50
   Shares; Mr. Hicks, 100 Shares; Mr. Price, 7,000 Shares; and Mr. Carter,
   20,075 Shares.

(3) Represent Shares registered in the name of Mr. Cassell's spouse. Mr.
    Cassell disclaims beneficial ownership of these Shares.

offer for or other acquisition of any securities of pcOrder, an election of
directors of pcOrder, or a sale or other transfer of a material amount of

RELATED PARTY TRANSACTIONS

   pcOrder has engaged in transactions and is a party to arrangements with
Trilogy and its affiliates as provided below. The following information should
be read together with "--Background of the Offer and the Merger." Additional
information with respect to the approximate dollar amount of certain
transactions between pcOrder and Trilogy during the past two full fiscal years
and the first nine months of 2000 is contained in Schedule III to this Offer to
Purchase.

   ASSET TRANSFER AGREEMENT. On June 1, 1996, pcOrder and Trilogy entered into
an Asset Transfer Agreement pursuant to which Trilogy transferred the assets
and liabilities of its pcOrder.com division to pcOrder in exchange for shares
of pcOrder's capital stock.

   REGISTRATION RIGHTS. Trilogy has the right, on no more than four occasions,
to require pcOrder to register the shares of pcOrder's capital stock held by
Trilogy within 180 days of such request. In addition, Trilogy has the right
under certain circumstances, to require pcOrder to include shares in a
registration statement registering other shares of capital stock of pcOrder.
pcOrder has agreed to indemnify Trilogy and provide contribution with respect
to liabilities under the Securities Act in connection with such registrations.
These registration rights expire on June 6, 2004.

   NON-COMPETITION AND NON-HIRE. Trilogy agreed not to engage in, directly or
indirectly, any business directly in competition with pcOrder at any time prior
to June 1, 1999. Further, during such period, Trilogy also agreed not to hire
or recruit any person who was, at the effective date of the agreement or within
the 12 month period preceding such effective date, an employee of the
pcOrder.com division of Trilogy. These non-competition and non-hire covenants
expired effective June 1, 1999. Since that date, there have been no contractual
restrictions on Trilogy's competing with pcOrder or hiring or recruiting
employees of pcOrder.

   TECHNOLOGY, SERVICES AND LICENSE AGREEMENT. On September 1, 1998, pcOrder
and Trilogy entered into a Technology, Services and License Agreement pursuant
to which each party granted the other access to specified intellectual property
and products owned by each party or jointly owned by the parties and existing
as of September 1, 1998, and any updates, changes to, and new releases of those
products or to sublicense any third party to do so, subject to certain
confidentiality and other restrictions.

   TRILOGY LICENSE TO PCORDER. Trilogy has granted pcOrder a nonexclusive,
irrevocable, perpetual, worldwide right and license under Trilogy's
intellectual property rights to make, use, reproduce, prepare derivative works
based upon, license, offer to license, import, export, publish, distribute,
perform, display, advertise, market, promote, service and or support certain of
pcOrder's e-commerce products in object code form, and to sublicense any third
party to do so, subject to the payment of royalties as described below.

   PCORDER LICENSE TO TRILOGY. pcOrder has granted Trilogy a nonexclusive,
irrevocable, perpetual, worldwide right and license to use pcOrder's
intellectual property rights to make, use, reproduce, prepare derivative works
based upon, license, export, publish, distribute, perform, display, advertise,
market, promote, service and support certain Trilogy products in object code
form and to sublicense any third party to do so, subject to the payment of
royalties as described below.

                                       41
<PAGE>

   Trigger Events. Each party is required to provide the other any updates,
   ---------------
changes to, and new releases of the aforementioned products until five years
after (i) a change in control of Trilogy or (ii) such time as pcOrder is no
longer required by generally accepted accounting principles to be consolidated
with Trilogy for financial reporting purposes (each, a "Trigger Event") but no
sooner than September 1, 2008. Neither party is restricted from entering into
or having similar agreements with third parties or doing any activity relating
to competitive products and services (involving none of the other party's
information or intellectual property). Notwithstanding the foregoing, to the
extent that any of Trilogy's intellectual property is not a replacement or of a
same, similar or equivalent general type as Trilogy's intellectual property
available prior to an event described above, pcOrder will not have rights to
such pre-Trigger Event intellectual property of Trilogy.

   Jointly-Developed Intellectual Property. Where at least one employee and/or
   ----------------------------------------
contractor of pcOrder and at least one employee and/or contractor of Trilogy
cooperate toward jointly creating, inventing or discovering new material
qualifying for either patent or copyright protection, the parties are required
to negotiate in good faith on a project-by-project basis to determine to what
extent such newly-developed material should be jointly owned. In the event of
joint ownership, the parties shall have an equal, undivided interest in such
patent, copyright or other intellectual property.

   License Fees. pcOrder and Trilogy are each obligated to pay to the other
   -------------
monthly royalties on license, subscription and software maintenance fees from
certain products that incorporate the other party's technology. For each of the
three years in the period ended December 31, 1999, pcOrder has committed to pay
royalties annually to Trilogy pursuant to the applicable agreements in effect
at that time, as follows:

  .  20% of the license fees derived from sales of certain of pcOrder's
     products;

  .  9% of software maintenance fees related to certain of pcOrder's
     products; and

  .  6% of subscription fees from sales of certain of pcOrder's products.

   In October 1999, pcOrder agreed to pay Trilogy an additional $1.0 million in
order to license Trilogy's technology for use in the office products industry.

   Indemnification. The agreement provides that each party will defend,
   ----------------
indemnify and hold harmless the other party for any claim against such other
party by any third party to the extent based on an actual or alleged:

  .  failure by a party to perform its obligations under the agreement;

  .  breach of representations or warranties;

  .  failure by a party to comply with governmental laws or regulations;

  .  intentional or grossly negligent acts or omissions on the part of a
     party; and

  .  infringement and Year 2000 failures.

   Consulting Services. Upon either party's request, the parties are required
   --------------------
to negotiate in good faith regarding the terms and conditions upon which either
party will perform consulting services reasonably requested by the other party.
The parties' obligations expire on the later of:

  .  seven years following a change in control of Trilogy or such time as
     pcOrder is no longer required by generally accepted accounting
     principles to be consolidated with Trilogy for financial accounting
     purposes; or

  .  September 1, 2010.

   Term. The agreement has a perpetual term, unless terminated earlier by
   -----
either party upon thirty-one days' prior notice of an uncured breach by the
other party, subject to extension for special circumstances, or the bankruptcy
of either of the parties.

                                       42
<PAGE>

   Assignment. Neither Trilogy nor pcOrder may assign the agreement without
   -----------
prior written consent, not to be unreasonably withheld, of the other party.
Either pcOrder or Trilogy may assign the agreement, without the other party's
consent, to a third party by operation of law or who purchases or otherwise
acquires substantially all of the assets of such assigning party and expressly
assumes in writing such assigning party's obligations under the agreement. The
assigning party shall continue to be subject to such obligations under the
agreement notwithstanding the assignment.

   TAX ALLOCATION AGREEMENT. On March 4, 1996, pcOrder and Trilogy entered into
a Tax Allocation Agreement pursuant to which pcOrder and Trilogy agreed to make
payments between each of them of the amount of taxes to be paid or received by
pcOrder as though pcOrder were to file separate federal, state and local income
tax returns rather than treating pcOrder as a consolidated subsidiary of
Trilogy for tax purposes.

   Rights of Trilogy. Under the agreement, Trilogy has some exclusive rights
   ------------------
including:

  .  all of the rights of a parent of a consolidated group (and similar
     rights provided for by applicable state and local law with respect to
     the parent of a combined, consolidated or unitary group);

  .  the right to serve as the sole and exclusive agent for pcOrder in any
     and all matters relating to the income, franchise and similar
     liabilities of pcOrder;

  .  the sole and exclusive responsibility for the preparation and filing of
     consolidated federal and consolidated or combined state and local income
     tax returns or amended returns; and

  .  the power, in its sole discretion, to contest or compromise any asserted
     tax adjustment or deficiency and to file, litigate or compromise any
     claim for refund on behalf of pcOrder.

   In addition, Trilogy provides the aforementioned services with respect to
pcOrder's separate state and local returns and pcOrder's foreign returns.

   Allocation of Liability. Each member of a consolidated group is jointly and
   ------------------------
severally liable for the federal income tax liability of each other member of
the consolidated group. Accordingly, although the agreement allocates tax
liabilities between pcOrder and Trilogy, during the periods in which pcOrder
was included in Trilogy's consolidated group, pcOrder could be liable in the
event that any federal tax liability was incurred, but not discharged, by any
other member of Trilogy's consolidated group. Pursuant to the agreement,
Trilogy is obligated to indemnify pcOrder for any tax liabilities, provided
that pcOrder has paid its allocated share of such liabilities to Trilogy.

   MANAGEMENT SERVICES AGREEMENT. On July 1, 1998, pcOrder and Trilogy entered
into a Management Services Agreement pursuant to which Trilogy provides
administrative and corporate support services to pcOrder.

   Mandatory Services. pcOrder is required to pay for the following services
   -------------------
during the term of the agreement:

  .  Tax Administration Services;

  .  Accounting/Payroll Services;

  .  Treasury/Finance Services;

  .  Corporate Finance Services;

  .  Recruiting Services; and

  .  Trilogy University Services/Training.

   The provision of these services may not be unilaterally terminated by either
party during the term of the agreement.


                                       43
<PAGE>

   Optional Services. Unless discontinued in writing, pcOrder must also pay
   ------------------
for the following optional services:


  .  Administrative Services (including purchasing, shipping and receiving
     services);

  .  Audit Services;

  .  Human Resources Services;

  .  Legal Services; and

  .  Customer Training.

   The provision of these optional services may be terminated by either party
upon 90 days' advance notice.

   Termination. This initial term agreement was scheduled to terminate on June
   ------------
30, 1999, and has been renewed for successive one-year renewal terms. The
agreement may be terminated:

  .  by either party within 30 days of an uncured material breach by the
     other party;

  .  by either party upon the liquidation or dissolution of the other party;

  .  by Trilogy, immediately upon notice to pcOrder, if pcOrder fails to pay
     the amount due to Trilogy under such agreement by the tenth day after
     notice of nonpayment is given; or

  .  on or after the date at which Trilogy ceases to own a majority of
     pcOrder's common stock.

   Assignment. Under the terms of the agreement, neither party may assign any
   -----------
of its rights or duties, including by operation of law. Trilogy may
subcontract any service in whole or in part to any person, including an
affiliate of Trilogy.

   SUBLEASE AGREEMENT. On June 1, 1999, pcOrder and Trilogy entered into a
Sublease Agreement, dated June 1, 1999, pursuant to which pcOrder subleases
its Austin facilities from Trilogy. The sublease terminates on April 7, 2005.
Annual rent started at $62,720 for the first year and escalates to $69,153 for
the last year. pcOrder must also pay Trilogy 31.5% of any additional amounts
due under Trilogy's master lease. If Trilogy renews the master lease under
which Trilogy leases pcOrder facilities, Trilogy is required to provide
pcOrder with the option of renewal at a rent of 31.5% of the rent due under
the renewed master lease. Trilogy has a right to purchase the premises from
its landlord. If Trilogy exercises its right to purchase the premises, the
sublease becomes a direct lease between Trilogy and pcOrder. pcOrder may not
assign its obligations under the sublease or sublease the facilities to a
third party without Trilogy's prior written approval.

INTERESTS OF CERTAIN PERSONS IN THE OFFER AND THE MERGER

   Consummation of the Offer and the Merger will have effects on the
compensation and incentive plans and arrangements in which officers and
directors of pcOrder are participants, as summarized below.

   TREATMENT OF STOCK OPTION PLANS. pcOrder currently maintains the following
stock option plans:

  .  1996 Stock Option Plan;

  .  1999 Stock Incentive Plan; and

  .  2000 Nonstatutory Stock Option Plan.

   In connection with the Merger, the pcOrder Board adopted resolutions to
clarify that its stock option plans permit the treatment of options in
accordance with the treatment provided for in the Merger Agreement. See
"Special Factors - The Merger Agreement - Treatment of Options and ESPP" above
for a discussion of the treatment of outstanding options to purchase Class A
Common Stock.

                                      44
<PAGE>

   SEVERANCE ARRANGEMENTS. No discussions have occurred as of the date hereof
between Trilogy and the executive officers regarding continued employment with
pcOrder or employment with Trilogy following the Effective Time of the merger,
except that, Christina Jones, pcOrder's President and Chief Operating Officer,
has had discussions with Trilogy concerning her future employment with pcOrder
or Trilogy. No agreement between Trilogy and Ms. Jones has been reached as of
the date hereof. Trilogy and the other executive officers may have similar
discussions in the future.

   Christina Jones, President and Chief Operating Officer. In November 1996,
   -------------------------------------------------------
pcOrder and Ms. Jones entered into an employment agreement that provided for an
employment period ending on November 1, 2000. The pcOrder Board has approved,
and has offered to Ms. Jones, an extension of her employment period under the
agreement for the period beginning on November 1, 2000 and ending on midnight
on the 30th day from and excluding the earlier to occur of: (a) the Effective
Time of the Merger; or (b) the termination of the Merger Agreement in
accordance with its terms.

   If Ms. Jones decides to accept such extension and, during the extended term,
the agreement is terminated without cause or if Ms. Jones terminates her
employment agreement for pcOrder's failure to comply with any material
provision of the agreement, Ms. Jones will continue to receive employee
benefits and monthly payments equal to one-twelfth of her current annual salary
for 12 months following the effective date of the termination.

   As of the date of this Offer to Purchase, Ms. Jones continues to be employed
by pcOrder but has not decided whether she will accept the extension of the
agreement.

   Richard Friedman, Vice President, General Counsel and Secretary. In July
   ----------------------------------------------------------------
1999, pcOrder and Mr. Friedman entered into an employment agreement pursuant to
which Mr. Friedman will continue to receive employee benefits and monthly
payments equal to one-twelfth of his then-current annual salary for six months
following the effective date of a termination of his agreement without cause.

   In October 1999, that agreement was amended to provide that if Mr.
Friedman's employment is terminated within three months following a "corporate
event," other than by pcOrder for "cause," pcOrder will pay Mr. Friedman one-
twelfth his base salary monthly for six months and a prorated bonus from July
1, 2000 through the date of termination at the rate of $50,000 per six-month
period, less any bonus amount previously paid by pcOrder to Mr. Friedman with
respect to such period. As used in Mr. Friedman's agreement, "corporate event"
is defined to be the first to occur of:

  .  the closing of a transaction in which a third-party, which includes
     Trilogy and its affiliates, acquires all or substantially all of
     pcOrder's stock or of the assets of pcOrder's enterprise software
     business;

  .  implementation of a corporate restructuring; and

  .  March 31, 2000.

   In addition, "cause" is defined to mean:

  .  material failure by Mr. Friedman to perform his duties as Vice President
     and General Counsel;

  .  a material breach by Mr. Friedman of his employment agreement;

  .  fraud or willful misconduct by Mr. Friedman; or

  .  conviction of Mr. Friedman for fraud, misappropriation, embezzlement, or
     any felony.

   Carleton K. Thompson, Vice President, Finance. In October 2000, pcOrder and
   ----------------------------------------------
Mr. Thompson entered into a retention agreement pursuant to which, if Mr.
Thompson is terminated at any time without "cause" or if, within three months
after completion of the Merger, Mr. Thompson or pcOrder terminates Mr.
Thompson's employment for any reason, then pcOrder will continue to pay Mr.
Thompson monthly for six months after the effective date of termination an
amount equal to one-twelfth of his annual base salary. In addition, pcOrder
will pay Mr. Thompson within one week of termination, a pro-rated bonus from
July 1, 2000 through the termination date at a rate of $50,000 per six-month
period less any bonus amount previously paid by pcOrder to Mr. Thompson with
respect to that six-month period.

                                       45
<PAGE>

   The agreement defines a reduction in Mr. Thompson's base salary as a
termination for purposes of calculating the benefits above. The agreement
defines cause to include an extended, unexcused absence, or misconduct of any
kind that is intended to or reasonably likely to cause harm to pcOrder or its
employees.

   INTERLOCKING DIRECTORS AND OFFICERS. In considering the recommendation of
pcOrder Board and the pcOrder Special Committee with respect to the Offer and
the Merger, stockholders should be aware that certain officers and directors of
Trilogy and pcOrder have interests in the Offer and the Merger that are
described below and that may present them with certain potential conflicts of
interest. Currently, of the five directors of pcOrder, one is also the majority
stockholder of Trilogy, Inc., the parent of Trilogy, and a director and
executive officer of Trilogy and another is a partner in a venture capital firm
that is also a stockholder of Trilogy, Inc.

   CERTAIN INTERESTS OF TRILOGY. Stockholders also should be aware that Trilogy
has certain interests that present actual or potential conflicts of interest in
connection with the Offer and the Merger. As a result of Trilogy's current
ownership of approximately 62% of the issued and outstanding shares of Class A
and Class B Common Stock of pcOrder, Trilogy may be deemed to control pcOrder.

   The pcOrder Special Committee and pcOrder Board were aware of these actual
and potential conflicts of interest and considered them along with the other
matters described under "--Recommendation of the pcOrder Special Committee and
the pcOrder Board; Fairness of the Offer and the Merger."

   INDEMNITY AGREEMENTS. In October, pcOrder entered into Indemnity Agreements
with each of its directors and executive officers. The Indemnity Agreements
require pcOrder to maintain directors' and officers' insurance that is at least
as favorable as the insurance then maintained by pcOrder. These agreements also
make indemnification by pcOrder mandatory, in most cases, for all expenses and
liabilities incurred by the officer or director in such capacity if that
officer or director acted in good faith and in a manner he or she reasonably
believed to be in, or not opposed to, the best interests of pcOrder and its
stockholders and, with respect to any third party criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful. These
agreements also make advancement of expenses by pcOrder mandatory in connection
with any proceeding to which the officer or director is a party or is
threatened to be made a party by reason of his or her status as an officer or
director. In addition, no legal action may be brought by, or in the right, of
pcOrder against the director or officer more than two years after the date of
accrual of such cause of action or such shorter period as may be provided by
law. Also see "--The Merger Agreement--Indemnification and Insurance" and "--
Certain Litigation."

(1) Because directors Barris, Lacy and Stearns own no Shares and the exercise
    prices of their options to purchase Shares are above the Offer Price, they
    are omitted from the table.

(2) Assumes that each of the executive officers enters into an agreement with
    pcOrder providing for the treatment of options in the manner specified in
    the Merger Agreement if the Merger is consummated (see "--The Merger
    Agreement--Treatment of Options and ESPP"), in which case the cash payments
    shown in this column will be made to each of them in respect of all their
    in-the-money options (i.e., where the exercise price is below the Offer
    Price), whether or not such options are vested at the Effective Time.

   Except as set forth in the table above, no director or executive officer is
entitled to receive any cash compensation in connection with the offer or the
Merger for Shares owned or options to purchase Shares. In addition, the Merger
Agreement contains certain provisions with respect to indemnification of
directors and executive officers, advancement of expenses and maintenance of
directors' and officers' liability insurance subsequent to the Effective Time.
See "--The Merger Agreement--Indemnification and Insurance."

CERTAIN FINANCIAL PROJECTIONS

   pcOrder does not, as a matter of course, make public forecasts or
projections as to future revenues, earnings or its general financial
performance, including the projections set forth below, and such information
was not prepared with a view to public disclosure. However, in connection with
Trilogy's evaluation of its investment in pcOrder (see "--Background of the
Offer and the Merger"), pcOrder shared with Trilogy and SG Cowen under a
confidentiality agreement, as well as with DRW, certain internally prepared
projections developed in the ordinary course of pcOrder's business and
planning, which are summarized below. These summary projections have been
included in this Offer to Purchase solely because they were made available to
Trilogy and its advisors in connection with their consideration of the Offer
and considered by DRW in rendering its fairness opinion.

   The projections set forth below were not prepared with a view to public
disclosure or in compliance with published guidelines of the SEC regarding
projections or the guidelines established by the American Institute of
Certified Public Accountants regarding projections. The projections were not
prepared in accordance with generally accepted accounting principles and were
not audited or reviewed by any independent accounting firm. No independent
accounting firm performed any services with respect thereto.

   The projections are forward-looking statements that are based on a number of
estimates and assumptions that involve judgments with respect to future
economic and competitive conditions, inflation rates and future

                                       47
<PAGE>

business conditions. These estimates and assumptions may not be realized and
are inherently subject to significant business, economic and competitive
uncertainties, many of which are beyond the control of pcOrder, as well as to
the inherent uncertainties resulting from pcOrder's deteriorating financial
condition. Therefore, there can be no assurance that the projections will prove
to be reliable estimates of future performance. It is quite likely that actual
results will vary materially from these estimates. The inclusion of these
projections is not a representation by any party that the estimates will be
realized. There can be no assurances in this regard. None of pcOrder, Trilogy,
Sub, DRW, SG Cowen, the Dealer Manager, the Information Agent nor any other
person assumes any responsibility for the accuracy of these projections.

</TABLE>

   In addition to estimates and assumptions about economic and competitive
uncertainties generally, the above projections reflected management's
assumption that pcOrder would restructure in part as follows:

  .  that pcOrder would terminate approximately 90 personnel and retain a
     core set of eight key customers;

  .  that pcOrder would recognize a restructuring charge of approximately
     $4.4 million in the fourth quarter of 2000;

  .  that pcOrder would exit the content business but receive no
     consideration for it;

  .  that pcOrder would exit the community business but receive no
     consideration for it; and

  .  that pcOrder would continue to pay Trilogy approximately $2.0 million
     per quarter through the second quarter of 2001 for modeling services
     related to pcOrder's contract with Compaq Computer Corporation.

   The summary projections provided above also were based on the following
projected software bookings and headcount at the end of each respective
quarter:

CERTAIN LITIGATION

   On October 25 and 26, 2000, and November 1, 2000, following Trilogy's
pcOrder's joint press release on October 25, 2000 announcing the Merger
Agreement, five purported stockholder class action lawsuits were filed against
pcOrder, its five directors, and Trilogy in the Delaware Court of Chancery
entitled SIDNEY ISSACS V. PCORDER.COM, ET AL., C.A. No. 18454; THOMAS L. HANLEY
V. PCORDER.COM, ET AL., C.A. No. 18458NC; ANDY HICKMAN V. PCORDER.COM, ET AL.
C.A. No. 18455; AMY COLLINS V. PCORDER.COM, ET AL., C.A. No. 18459NC and
JEANETTE CORPUS V. PCORDER.COM, ET AL., C.A. No. 18472NC (collectively the
"Delaware Complaints"). On October 26, 2000, a similar purported class action
lawsuit was filed against the same defendants in the District Court of Travis
County, Texas entitled JAMES F. MARTENS V. PCORDER.COM ET AL., Court No.
GN003141 (the "Texas Petition").

                                       48
<PAGE>

   The allegations in each of the Delaware Complaints are identical, the only
difference being the name of the purported class representative in each action.
The Delaware Complaints all allege the same grounds for relief, namely that the
defendants breached their fiduciary duty to the stockholders by orchestrating
the purchase of the Shares so that the public stockholders were deprived of an
"adequate" or "fair" price. The Delaware Complaints also allege that Trilogy
has a conflict of interest and committed this breach of fiduciary duty solely
to benefit itself in the Offer and Merger. The individual defendants are
alleged to have "acquiesced" in Trilogy's wrongdoing. The Delaware Complaints
also allege that pcOrder's earning results were withheld until after the Merger
Agreement was announced in order to artificially limit the price of the Shares.

   The allegations in the Texas Petition, while not identical to those in the
Delaware Complaints, claim essentially the same basic grounds for relief.
According to the Texas Petition, the individual defendants breached their
fiduciary duty to stockholders of pcOrder in connection with the Merger
Agreement by failing to provide an appropriate process for eliciting and
evaluating bids. The Texas Petition further alleges that the actions of the
individual defendants were taken solely to serve their own interests and/or the
interests of pcOrder's largest stockholder, while inhibiting the "maximization"
of stockholder value. The Texas Petition also contains allegations regarding
the timing of the announcement of the Merger Agreement similar to those in the
Delaware Complaints.

   All six of the lawsuits seek declarations that the defendants breached their
fiduciary duties (or acquiesced in the breach), unspecified damages and an
award of attorneys' fees, among other relief. All of the lawsuits include a
request for an injunction declaring the suits maintainable as class actions.
Each of the lawsuits seeks to enjoin the transactions contemplated by the
Merger Agreement, including the Offer and the Merger, or to rescind the
transactions in the event they are consummated or to obtain rescissory damages.
The Texas Petition seeks further declarations that the approval of the Merger
Agreement constituted a breach of fiduciary duty and as a result is a nullity,
and a further injunction directing the individual defendants to obtain a
transaction that is in the best interests of stockholders.

   Although all of the lawsuits include general claims for injunctive relief,
to the knowledge of pcOrder and Trilogy, none of the plaintiffs has filed a
motion requesting the Delaware and Texas courts to prohibit the closing of the
Offer or the Merger. pcOrder and Trilogy each intends to defend against all of
these lawsuits vigorously. The complaints in the lawsuits have been filed as
exhibits to the Offer Statement on Schedule TO filed by pcOrder and Trilogy
with the SEC (see "The Tender Offer--Section 15. Miscellaneous").

                                       49
<PAGE>

                                THE TENDER OFFER

   1. TERMS OF THE OFFER; EXPIRATION DATE. Upon the terms and subject to the
conditions of the Offer (including, if the Offer is extended or amended, the
terms and conditions of such extension or amendment), Trilogy will accept for
payment, and will pay for, any and all Shares validly tendered prior to the
Expiration Date (as hereinafter defined) and not withdrawn as permitted by "--
Section 4. Withdrawal Rights." The term "Expiration Date" means 12:00 midnight,
New York City time, on Wednesday, December 6, 2000, unless and until Trilogy
(but subject to the terms and conditions of the Merger Agreement) shall have
extended the period during which the Offer is open, in which event the term
"Expiration Date" shall mean the latest time and date at which the Offer, as so
extended by Trilogy, shall expire.

   Subject to the provisions of the Merger Agreement, Trilogy may waive any or
all of the conditions to its obligation to purchase Shares pursuant to the
Offer. If by the initial Expiration Date or any subsequent Expiration Date any
or all of the conditions to the Offer have not been satisfied or waived,
subject to the provisions of the Merger Agreement, Trilogy may elect to (i)
terminate the Offer and return all tendered Shares to tendering stockholders;
(ii) waive all of the unsatisfied conditions and, subject to any required
extension, purchase all Shares validly tendered by the Expiration Date and not
properly withdrawn; or (iii) extend the Offer and, subject to the right of
stockholders to withdraw Shares until the new Expiration Date, retain the
Shares that have been tendered until the expiration of the Offer as extended.

   The Merger Agreement provides that, without the consent of pcOrder
(expressed in a resolution adopted by both the pcOrder Special Committee and
the pcOrder Board), Trilogy will not: (i) decrease the Offer Price, or change
the form of consideration to be paid in the Offer; (ii) impose any additional
conditions to the Offer from those set forth in "--Section 13. Certain
Conditions to the Offer;" (iii) reduce the number of Shares subject to the
Offer; or (iv) otherwise amend the Offer in a manner that would adversely
affect the holders of Shares.

   Trilogy acknowledges that Rule 14e-1(c) under the Exchange Act requires
Trilogy to pay the consideration offered or return the Shares tendered promptly
after the termination or withdrawal of the Offer.

   Notwithstanding the foregoing, Trilogy has the right, without the consent of
pcOrder, to extend the Offer beyond the initial Expiration Date in the
following events: (i) from time to time if, at the initial Expiration Date (or
any subsequent Expiration Date), any of the conditions of the Offer shall not
have been satisfied or waived; (ii) for any period required by any rule,
regulation, interpretation or position of the SEC or the staff thereof
applicable to the Offer or any period required by applicable law; or (iii)
pursuant to an amendment to the Offer providing for a "Subsequent Offering
Period" (as defined below) not to exceed twenty business days, to the extent
permitted under, and in compliance with, Rule 14d-11 under the Exchange Act. In
addition, if at any scheduled Expiration Date of the Offer any of the
conditions of the Offer have not been satisfied or waived by Trilogy but are
reasonably capable of being satisfied, Trilogy must extend the Offer for ten
calendar days from the then-scheduled Expiration Date of the Offer; provided
that Trilogy is not obligated to extend the Offer pursuant to this requirement
more than once.

   Pursuant to Rule 14d-11 under the Exchange Act, Trilogy may, subject to
certain conditions, provide a subsequent offering period following the
expiration of the Offer on the Expiration Date (a "Subsequent Offering
Period"). A Subsequent Offering Period is an additional period of time from
three business days to twenty business days in length, beginning after Trilogy
purchases Shares tendered in the Offer, during which stockholders may tender,
but not withdraw, their Shares and receive the Offer Price. It is a condition
to Trilogy's right to extend the Offer to provide for a Subsequent Offering
Period that, in connection with such extension, Trilogy must waive, with
respect to all Shares validly tendered during the Subsequent Offering Period,
all conditions of the Offer.

   Following the satisfaction or waiver of the conditions set forth in "--
Section 13. Certain Conditions to the Offer," the Merger Agreement requires
Trilogy to accept for payment and pay for all Shares validly tendered and not
withdrawn as soon as it is permitted to do so under applicable law.

                                       50

   Any such extension, delay, termination, waiver or amendment will be followed
as promptly as practicable by public announcement thereof and, in the case of
an extension, the announcement will be made no later than 9:00 a.m., New York
City time, on the next business day after the previously scheduled Expiration
Date. Subject to applicable law (including Rules 13e-3(d), l4d-4(d), 14d-6(c)
and 14e-l under the Exchange Act, which require that material changes be
promptly disseminated to stockholders in a manner reasonably designed to inform
them of such changes) and without limiting the manner in which Trilogy may
choose to make any public announcement, Trilogy shall have no obligation to
publish, advertise or otherwise communicate any such public announcement other
than by issuing a press release to the Dow Jones News Service.

   If Trilogy is delayed in its payment for the Shares or is unable to pay for
Shares pursuant to the Offer for any reason, then, without prejudice to
Trilogy's rights under the Offer, the Depositary may retain tendered Shares on
behalf of Trilogy, and such Shares may not be withdrawn, except to the extent
tendering stockholders are entitled to withdrawal rights as described in "--
Section 4. Withdrawal Rights." However, the ability of Trilogy to delay the
payment for Shares which Trilogy has accepted for payment is limited by Rule
14e-1(c) under the Exchange Act, which requires that the bidder pay the
consideration offered or return the securities deposited by, or on behalf of,
holders of securities promptly after the termination or withdrawal of the
Offer.

   If Trilogy makes a material change in the terms of the Offer or the
information concerning the Offer, or if it waives a material condition of the
Offer, Trilogy will extend the Offer to the extent required by Rules 13e-3(d),
14d-4(d), l4d-6(c) and 14e-1 under the Exchange Act. The minimum period during
which the Offer must remain open following material changes in the terms of the
Offer or information concerning the Offer, other than a change in price or
change in percentage of securities sought, will depend upon the facts and
circumstances then existing, including the relative materiality of the changed
terms or information. In a public release, the SEC has stated its views that an
Offer must remain open for a minimum period of time following a material change
in the terms of the Offer and that waiver of a material condition is a material
change in the terms of the Offer. The release states that an Offer should
remain open for a minimum of five business days from the date a material change
is first published or sent or given to security holders and that, if material
changes are made with respect to information not materially less significant
than the Offer Price and the number of Shares being sought, a minimum of ten
business days may be required to allow for adequate dissemination to
stockholders and investor response. For purposes of the Offer, a "business day"
means any day other than a Saturday, Sunday or United States federal holiday
and consists of the time period from 12:01 a.m. through 12:00 midnight, New
York City time. The requirement to extend the Offer will not apply to the
extent that the number of business days remaining between the occurrence of the
change and the then-scheduled Expiration Date equals or exceeds the minimum
extension period that would be required because of such amendment. If, prior to
the Expiration Date, Trilogy increases the consideration offered to holders of
Shares pursuant to the Offer, such increased consideration will be paid to all
holders whose Shares are purchased in the Offer whether or not such Shares were
tendered prior to such increase.

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

   2. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES. Upon the terms and subject
to the conditions of the Offer (including, if the Offer is extended or amended,
the terms and conditions of any such extension or amendment), Trilogy will
accept for payment, and will pay for, all Shares validly tendered prior to the
Expiration Date and not properly withdrawn, as soon as practicable after the
Expiration Date. Subject to applicable rules of the SEC, Trilogy expressly
reserves the right to delay acceptance for payment of, or payment for, Shares
in order to comply in whole or in part with any other applicable law. If
Trilogy desires to delay payment for Shares accepted for payment pursuant to
the Offer, and such delay would otherwise be in contravention of Rule 14e-1(c)
of the Exchange Act, Trilogy will otherwise extend the Offer.

                                       51
<PAGE>

   In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of (i)
the certificates evidencing such Shares (the "Certificates") or timely
confirmation (a "Book-Entry Confirmation") of a book-entry transfer of such
Shares into the Depositary's account at the book-entry transfer facility, The
Depository Trust Company ("DTC"), pursuant to the procedures set forth in "--
Section 3. Procedures for Tendering Shares," (ii) the Letter of Transmittal (or
a facsimile thereof), properly completed and duly executed, with any required
signature guarantees or, in the case of a book-entry transfer, an Agent's
Message (as defined below) in lieu of the Letter of Transmittal and (iii) any
other documents required by the Letter of Transmittal.

   For purposes of the Offer, Trilogy will be deemed to have accepted for
payment, and thereby purchased, Shares validly tendered and not properly
withdrawn as, if and when Trilogy gives oral or written notice to the
Depositary, as agent for the tendering stockholders, of Trilogy's acceptance
for payment of such Shares pursuant to the Offer. Upon the terms and subject to
the conditions of the Offer, payment for Shares accepted for payment pursuant
to the Offer will be made by deposit of the purchase price therefor with the
Depositary, which will act as agent for tendering stockholders for the purpose
of receiving payments from Trilogy and transmitting such payments to tendering
stockholders whose Shares have been accepted for payment. Under no
circumstances will interest on the Offer Price for Shares be paid, regardless
of any delay in making such payment.

   If any tendered Shares are not accepted for payment for any reason pursuant
to the terms and conditions of the Offer, or if Certificates are submitted
evidencing more Shares than are tendered, Certificates evidencing unpurchased
Shares will be returned, without expense to the tendering stockholder (or, in
the case of Shares tendered by book-entry transfer into the Depositary's
account at DTC pursuant to the procedure set forth in "--Section 3. Procedures
for Tendering Shares," such Shares will be credited to an account maintained at
DTC), as promptly as practicable following the expiration or termination of the
Offer.

   If, on or prior to the Expiration Date, Trilogy shall increase the
consideration offered to any holders of Shares pursuant to the Offer, such
increased consideration shall be paid to all holders of Shares that are
purchased pursuant to the Offer, whether or not such Shares were tendered,
accepted for payment or paid for prior to such increase in consideration.

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

   3. PROCEDURES FOR TENDERING SHARES. Except as set forth below, in order for
Shares to be validly tendered pursuant to the Offer, the Letter of Transmittal
(or a facsimile thereof), properly completed and duly executed, together with
any required signature guarantees (or, in the case of a book-entry transfer, an
Agent's Message in lieu of the Letter of Transmittal) and any other documents
required by the Letter of Transmittal, must be received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase and
either (i) the Certificates evidencing tendered Shares must be received by the
Depositary at such address or such Shares must be tendered pursuant to the
procedure for book-entry transfer described below and a Book-Entry Confirmation
must be received by the Depositary (including an Agent's Message if the
tendering stockholder has not delivered a Letter of Transmittal), in each case
on or prior to the Expiration Date; or (ii) the tendering stockholder must
comply with the guaranteed delivery procedures described below. No alternative,
conditional or contingent tenders will be accepted. The term "Agent's Message"
means a message, transmitted by electronic means to, and received by, the
Depositary and forming a part of a Book-Entry Confirmation that states that DTC
has received an express acknowledgment from the participant in DTC tendering
the Shares that are the subject of such book-entry confirmation, that such
participant has received and agrees to be bound by the terms of the Letter of
Transmittal and that Trilogy may enforce such agreement against such
participant.

                                       52
<PAGE>

   BOOK-ENTRY TRANSFER. The Depositary will establish accounts with respect to
the Shares at DTC for purposes of the Offer within two business days after the
date of this Offer to Purchase. Any financial institution that is a participant
in DTC's system may make a book-entry delivery of Shares by causing DTC to
transfer such Shares into the Depositary's account in accordance with DTC's
procedures for such transfer. However, although delivery of Shares may be
effected through book-entry transfer at DTC, either the Letter of Transmittal
(or a facsimile thereof), properly completed and duly executed, together with
any required signature guarantees, or an Agent's Message in lieu of the Letter
of Transmittal, and any other required documents, must, in any case, be
received by the Depositary at one of its addresses set forth on the back cover
of this Offer to Purchase prior to the Expiration Date, or the tendering
stockholder must comply with the guaranteed delivery procedure described below.
Delivery of documents to DTC does not constitute delivery to the depositary.

   SIGNATURE GUARANTEES. Signatures on all Letters of Transmittal must be
guaranteed by a firm which is a member of the Security Transfer Agents
Medallion Program, the New York Stock Exchange Medallion Guarantee Program or
the Stock Exchange Medallion Program or is otherwise an "Eligible Guarantor
Institution" (as such term is defined in Rule 17Ad-5 under the Exchange Act)
(each, an "Eligible Institution"), except in cases where Shares are tendered
(i) by a registered holder of Shares who has not completed either the box
entitled "Special Payment Instructions" or the box entitled "Special Delivery
Instructions" on the Letter of Transmittal or (ii) for the account of an
Eligible Institution. If a Certificate is registered in the name of a person
other than the signatory of the Letter of Transmittal (or a facsimile thereof),
or if payment is to be made, or a Certificate not accepted for payment or not
tendered is to be returned, to a person other than the registered holder(s),
then the Certificate must be endorsed or accompanied by appropriate stock
powers, in either case signed exactly as the name(s) of the registered
holder(s) appear(s) on the Certificate, with the signature(s) on such
Certificate or stock powers guaranteed by an Eligible Institution. If the
Letter of Transmittal or stock powers are signed or any certificate is endorsed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity,
such persons should so indicate when signing and, unless waived by Trilogy,
proper evidence satisfactory to Trilogy of their authority to so act must be
submitted. See Instructions 1, 5, 6 and 7 of the Letter of Transmittal.

   GUARANTEED DELIVERY. If a stockholder desires to tender Shares pursuant to
the Offer and the Certificates evidencing such stockholder's Shares are not
immediately available or such stockholder cannot deliver the Certificates and
all other required documents to the Depositary prior to the Expiration Date, or
such stockholder cannot complete the procedure for delivery by book-entry
transfer on a timely basis, such Shares may nevertheless be tendered, provided
that all the following conditions are satisfied:

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

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

     (iii) the Certificates (or a Book-Entry Confirmation) evidencing all
  tendered Shares, in proper form for transfer, in each case together with
  the Letter of Transmittal (or a facsimile thereof), properly completed and
  duly executed, with any required signature guarantees (or, in connection
  with a book-entry transfer, an Agent's Message), and any other documents
  required by the Letter of Transmittal are received by the Depositary within
  three trading days after the date of execution of such Notice of Guaranteed
  Delivery. A "trading day" is any day on which the New York Stock Exchange
  and the Nasdaq National Market System are open for business.

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

   In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of (i)
the Certificates evidencing such Shares, or a Book-Entry

                                       53
<PAGE>

Confirmation of the delivery of such Shares, (ii) a Letter of Transmittal (or a
facsimile thereof), properly completed and duly executed, with any required
signature guarantees (or, in the case a book-entry transfer, an agent's
message), and (iii) any other documents required by the Letter of Transmittal.
Accordingly, tendering stockholders may be paid at different times depending
upon when Certificates for Shares or Book-Entry Confirmations with respect to
the Shares are actually received by the Depositary. UNDER NO CIRCUMSTANCES WILL
INTEREST BE PAID ON THE PURCHASE PRICE TO BE PAID BY TRILOGY FOR THE TENDERED
SHARES, REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH
PAYMENT.

   THE METHOD OF DELIVERY OF CERTIFICATES AND ALL OTHER REQUIRED DOCUMENTS,
INCLUDING DELIVERY THROUGH DTC, IS AT THE OPTION AND RISK OF THE TENDERING
STOCKHOLDER, AND THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED
BY THE DEPOSITARY. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT
REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME
SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

   DETERMINATION OF VALIDITY. All questions as to the validity, form,
eligibility (including time of receipt) and acceptance for payment of any
tender of Shares will be determined by Trilogy in its sole discretion, which
determination shall be final and binding on all parties. Trilogy reserves the
absolute right to reject any and all tenders determined by it not to be in
proper form or the acceptance for payment of which may, in the opinion of its
counsel, be unlawful. Trilogy also reserves the absolute right to waive any
condition of the Offer or any defect or irregularity in the tender of any
particular Shares or any particular stockholder, whether or not similar defects
or irregularities are waived in the case of other stockholders, and Trilogy's
interpretation of the terms and conditions of the Offer will be final and
binding on all persons. No tender of Shares will be deemed to have been validly
made until all defects and irregularities have been cured or waived to the
satisfaction of Trilogy. None of Sub, Trilogy, the Dealer Manager, the
Depositary, the Information Agent or any other person will be under any duty to
give notification of any defects or irregularities in tenders or incur any
liability for failure to give any such notification.

   OTHER REQUIREMENTS. By executing the Letter of Transmittal as set forth
above, a tendering stockholder irrevocably appoints the designees of Trilogy
named in the Letter of Transmittal as such stockholder's proxies, each with
full power of substitution, in the manner set forth in the Letter of
Transmittal, to the full extent of such stockholder's rights with respect to
the Shares tendered by such stockholder and accepted for payment by Trilogy
(and with respect to any and all other Shares or other securities issued or
issuable in respect of such Shares on or after the date of this Offer to
Purchase). All such proxies shall be considered coupled with an interest in the
tendered Shares. Such appointment will be effective when, and only to the
extent that, Trilogy accepts such Shares for payment. Upon such acceptance for
payment, all prior proxies given by such stockholder with respect to such
Shares (and such other Shares and securities) will be revoked without further
action, and no subsequent proxies may be given nor any subsequent written
consent executed by such stockholder (and, if given or executed, will not be
deemed to be effective) with respect thereto. The designees of Trilogy will,
with respect to the Shares for which the appointment is effective, be empowered
to exercise all voting and other rights of such stockholder as they in their
sole discretion may deem proper at any annual or special meeting of pcOrder's
stockholders or any adjournment or postponement thereof, by written consent in
lieu of any such meeting or otherwise. Trilogy reserves the right to require
that, in order for Shares to be deemed validly tendered, immediately upon
Trilogy's payment for such Shares, Trilogy must be able to exercise full voting
rights with respect to such Shares.

   The acceptance for payment by Trilogy of Shares pursuant to any of the
procedures described above will constitute a binding agreement between the
tendering stockholder and Trilogy upon the terms and subject to the conditions
of the Offer.

   TO PREVENT BACKUP FEDERAL INCOME TAX WITHHOLDING WITH RESPECT TO PAYMENTS
MADE TO CERTAIN STOCKHOLDERS OF THE PURCHASE PRICE OF SHARES PURCHASED PURSUANT
TO THE OFFER, EACH SUCH STOCKHOLDER MUST PROVIDE THE

                                       54
<PAGE>

DEPOSITARY WITH SUCH STOCKHOLDER'S CORRECT TAXPAYER IDENTIFICATION NUMBER
("TIN") AND CERTIFY THAT SUCH STOCKHOLDER IS NOT SUBJECT TO BACKUP FEDERAL
INCOME TAX WITHHOLDING BY COMPLETING THE SUBSTITUTE FORM W-9 IN THE LETTER OF
TRANSMITTAL. IF BACKUP WITHHOLDING APPLIES WITH RESPECT TO A STOCKHOLDER, THE
DEPOSITARY IS REQUIRED TO WITHHOLD 31% OF ANY PAYMENTS MADE TO SUCH
STOCKHOLDER. SEE INSTRUCTION 10 OF THE LETTER OF TRANSMITTAL. NON-UNITED STATES
HOLDERS MUST SUBMIT A COMPLETED FORM W-8 OR FORM W-8BEN TO AVOID BACKUP
WITHHOLDING. SEE INSTRUCTION 12 OF THE LETTER OF TRANSMITTAL. THESE FORMS MAY
BE OBTAINED FROM THE DEPOSITARY.

   4. WITHDRAWAL RIGHTS. Tenders of the Shares made pursuant to the Offer are
irrevocable, except that such Shares may be withdrawn at any time prior to the
Expiration Date and, unless theretofore accepted for payment by Trilogy
pursuant to the Offer, may also be withdrawn at any time on or after January 4,
2001. If Trilogy extends the Offer, is delayed in its acceptance for payment of
Shares or is unable to accept Shares for payment pursuant to the Offer for any
reason, then, without prejudice to Trilogy's rights under the Offer, the
Depositary may, nevertheless, on behalf of Trilogy, retain tendered Shares, and
such Shares may not be withdrawn except to the extent that tendering
stockholders are entitled to withdrawal rights as described in this Section 4.
Any such delay will be accompanied by an extension of the Offer to the extent
required by law.

   For a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase. Any
such notice of withdrawal must specify the name of the person who tendered the
Shares to be withdrawn, the number of Shares to be withdrawn and the name of
the registered holder of such Shares, if different from that of the person who
tendered such Shares. If Certificates evidencing Shares to be withdrawn have
been delivered or otherwise identified to the Depositary, then, prior to the
physical release of such Certificates, the serial numbers shown on such
Certificates must be submitted to the Depositary and the signature(s) on the
notice of withdrawal must be guaranteed by an Eligible Institution, unless such
Shares have been tendered for the account of an Eligible Institution. If Shares
have been tendered pursuant to the procedure for book-entry transfer as set
forth in "--Section 3. Procedures for Tendering Shares," any notice of
withdrawal must specify the name and number of the account at DTC to be
credited with the withdrawn Shares or must otherwise comply with DTC's
procedures.

   Withdrawals of tenders of Shares may not be rescinded, and Shares properly
withdrawn will thereafter be deemed not validly tendered for purposes of the
Offer. However, withdrawn Shares may be retendered by again following the
procedures described in "--Section 3. Procedures for Tendering Shares," at any
time prior to the Expiration Date or during a Subsequent Offering Period under
Rule 14d-11 under the Exchange Act, if the Offer is amended to provide for one.

   No withdrawal rights will apply to Shares tendered into a Subsequent
Offering Period under Rule 14d-11 under the Exchange Act and no withdrawal
rights apply during a Subsequent Offering Period under Rule 14d-11 under the
Exchange Act with respect to Shares tendered in the Offer and accepted for
payment.

   All questions as to the form and validity (including time of receipt) of any
notice of withdrawal will be determined by Trilogy, in its sole discretion,
whose determination will be final and binding. None of Trilogy, Sub, the Dealer
Manager, the Depositary, the Information Agent or any other person will be
under duty to give notification of any defects or irregularities in any notice
of withdrawal or incur any liability for failure to give any such notification.

   5. CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES. The receipt of cash for
Shares pursuant to the Offer or in the Merger will be a taxable transaction for
United States federal income tax purposes under the Internal Revenue Code of
1986, as amended ("the Code"), and may also be a taxable transaction under
applicable state, local or foreign tax laws. Generally, a stockholder who
receives cash in exchange for Shares pursuant to the Offer or the Merger will
recognize a gain or loss for United States federal income tax purposes equal to
the

                                       55
<PAGE>

difference between the amount of cash received and such stockholder's adjusted
tax basis in the Shares exchanged therefor. Provided that such Shares
constitute capital assets in the hands of the stockholder, such gain or loss
will be a capital gain or loss, and will be a long-term capital gain or loss if
the holder has held the Shares for more than one year at the time of sale. Gain
or loss will be calculated separately for each block of Shares tendered
pursuant to the Offer or converted pursuant to the Merger. The maximum United
States federal income tax rate applicable to individual taxpayers on long-term
capital gain is 20%, and the deductibility of capital losses is subject to
limitations. All stockholders should consult with their own tax advisors as to
the particular tax consequences of the Offer and the Merger to them, including
the applicability and effect of the alternative minimum tax and any state,
local or foreign income and other tax laws and of changes in such tax laws.

   The foregoing discussion may not be applicable to a stockholder who acquired
Shares pursuant to the exercise of employee stock options or otherwise as
compensation or to a stockholder who is otherwise subject to special tax
treatment under the Code (for example, brokers, dealers in securities, banks,
insurance companies, tax-exempt organizations and financial institutions and
taxpayers that are neither citizens nor residents of the United States or that
are foreign corporations or foreign estates or trusts as to the United States).

   THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED
FOR GENERAL INFORMATION ONLY AND IS BASED UPON PRESENT LAW, WHICH IS SUBJECT TO
CHANGE, POSSIBLY WITH RETROACTIVE EFFECT. STOCKHOLDERS ARE URGED TO CONSULT
THEIR TAX ADVISORS WITH RESPECT TO THE SPECIFIC TAX CONSEQUENCES OF THE OFFER
AND THE MERGER TO THEM, INCLUDING THE APPLICATION AND EFFECT OF THE ALTERNATIVE
MINIMUM TAX, AND STATE, LOCAL OR NON-UNITED STATES INCOME AND OTHER TAX LAWS.

   6. PRICE RANGE OF SHARES. The Shares are listed and principally traded on
the Nasdaq National Market System under the symbol "PCOR." The following table
sets forth, for the calendar quarters indicated, the high and low closing sales
prices per Share on the Nasdaq National Market System as reported by published

   8. CERTAIN INFORMATION CONCERNING TRILOGY AND SUB. Trilogy Software, Inc., a
Delaware corporation, providers sales, marketing and business-to-business e-
commerce applications. Trilogy's software solutions are designed to integrate
each function in a company's sales and marketing operation, including pricing
management, product management, sales, commissions, promotions, contract
management and channel management. In addition, Trilogy's software solutions
are designed to enable companies to engage in e-commerce as well as improve
channel management processes.

   Sub is a Delaware corporation and to date has engaged in no activities other
than those incident to its formation and entry into the Merger Agreement. Sub
is a direct wholly-owned subsidiary of Trilogy.

   The principal executive offices of both Trilogy and Sub are located at 6034
West Courtyard Drive, Austin, Texas 78730. The name, citizenship, business
address, principal occupation or employment and five-year employment history
for each of the directors and executive officers of Trilogy and Sub and certain
other information is set forth in Schedule I hereto.

   Trilogy owns 10,316,620 shares of pcOrder's Class B Common Stock, which are
immediately convertible into 10,316,620 Shares, representing approximately 62%
of the outstanding combined Class A Common Stock and Class B Common Stock of
pcOrder and approximately 93% of the voting power thereof, as of October 25,
2000.

   Trilogy may be deemed to be controlled by Joseph A. Liemandt, who is
Trilogy's Chairman and Chief Executive Officer and who is the majority
stockholder of Trilogy, Inc., Trilogy's parent.

   Except as provided in the Merger Agreement and as otherwise described in
this Offer to Purchase, (i) none of Trilogy nor any of its subsidiaries nor, to
the best of its knowledge, any of the persons listed in Schedule I to this
Offer to Purchase, has any contract, arrangement, understanding or relationship
with any other person with respect to any securities of pcOrder, including, but
not limited to, any contract, arrangement, understanding or relationship
concerning the transfer or the voting of any such securities, finder's fees,
joint ventures, loan or option arrangements, puts or calls, guaranties of
loans, guaranties against loss, guarantees of profits, division of profits or
loss or the giving or withholding of proxies, and (ii) none of Trilogy nor, to
the best its knowledge, any of the persons listed on Schedule I to this Offer
to Purchase, has had any business relationship or transaction with pcOrder or
any of its executive officers, directors or affiliates that is required to be
reported under the rules and regulations of the SEC applicable to the Offer.
See "Special Factors--Transactions and Arrangements Concerning the Shares" for
a summary description of the mutual contacts, negotiations and transactions
between Trilogy or any of its subsidiaries or any of the persons listed on
Schedule I to this Offer to Purchase, on the one hand, and pcOrder or its
affiliates, on the other hand, concerning a merger, consolidation or
acquisition, tender offer or other acquisition of securities, an election of
directors or a sale or other transfer of a material amount of assets.

   9. SOURCE AND AMOUNT OF FUNDS. The total amount of funds required by Trilogy
to consummate the Offer and the Merger and to pay related fees and expenses is
estimated to be approximately $49 million. Trilogy will obtain such funds from
existing resources, including internally generated funds of Trilogy and its
subsidiaries. The Offer is not conditioned on any financing arrangements. See
"Special Factors--The Merger Agreement--Representations and Warranties."

   10. DIVIDENDS AND DISTRIBUTIONS. Pursuant to the Merger Agreement, without
the prior approval of Trilogy or as otherwise contemplated in the Merger
Agreement, pcOrder has agreed to not (i) declare or pay any dividend or make
any distribution with respect to any shares of its capital stock, (ii) purchase
or otherwise acquire, or propose to purchase or otherwise acquire, any
outstanding share of its capital stock, and (iii) issue, sell, pledge, dispose
or encumber any capital stock of pcOrder or any of its subsidiaries except as
set forth in the Merger Agreement.

   11. CERTAIN EFFECTS OF THE OFFER ON THE MARKET FOR THE SHARES.

   EFFECT ON THE MARKET FOR THE SHARES. The purchase of Shares by Trilogy
pursuant to the Offer will reduce the number of Shares that might otherwise
trade publicly and will reduce the number of holders of Shares, which could
adversely affect the liquidity and market value of the remaining Shares held by
the public.

   STOCK QUOTATIONS. The Shares are currently quoted on the Nasdaq National
Market System, which constitutes the principal trading market for the Shares.
Depending upon the number of Shares purchased pursuant to the Offer, the Shares
may no longer meet the standards for continued quotation on the Nasdaq National
Market System.

   According to the Nasdaq National Market System's published guidelines, the
Shares would not be eligible to be included for listing on the Nasdaq National
Market System if, among other things, the number of Shares publicly held falls
below 750,000, the number of holders of round lots of Shares falls below 400 or
the aggregate market value of such publicly held Shares falls below $5,000,000.
If, as a result of the purchase of Shares pursuant to the Offer, the Merger or
otherwise, the Shares no longer meet the requirements of the Nasdaq National
Market System for continued listing, the listing of the Shares might be
discontinued and, in such event, the market for the Shares could be adversely
affected. In the event the Shares were no longer eligible for listing on the
Nasdaq National Market System, quotations might still be available from other
sources. The extent of the public market for the Shares and the availability of
such quotations would, however, depend upon the number of holders of such
Shares remaining at such time, the interest in maintaining a market in such
Shares on the part of securities firms, the possible termination of
registration of such Shares under the Exchange Act as described below and other
factors.

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

   EXCHANGE ACT REGISTRATION. The Shares are currently registered under the
Exchange Act. Such registration may be terminated upon application by pcOrder
to the SEC if the Shares are not listed on a national securities exchange,
quoted on an automated inter-dealer quotation system or held by 300 or more
holders of record. The termination of the registration of the Shares under the
Exchange Act would reduce the information required to be furnished by pcOrder
to holders of Shares and to the SEC and would make certain provisions of the
Exchange Act, such as the short-swing profit recovery provisions of Section
16(b), the requirement of furnishing a proxy statement in connection with
stockholders' meetings and the requirements of Rule 13e-3 under the Exchange
Act with respect to "going private" transactions, no longer applicable to the
Shares. In addition, "affiliates" of pcOrder and persons holding "restricted
securities" of pcOrder may be deprived of the ability to dispose of such
securities pursuant to Rule 144 promulgated under the Securities Act. If
registration of the Shares under the Exchange Act were terminated, the Shares
would no longer be "margin securities" or be eligible for quotation on the
Nasdaq National Market System. Trilogy currently intends to seek to cause
pcOrder to terminate the registration of the Shares under the Exchange Act as
soon as practicable after consummation of the Offer if the requirements for
termination of registration are met.

   12. FEES AND EXPENSES. SG Cowen is acting as financial advisor to Trilogy in
connection with the transactions contemplated by the Merger Agreement and is
also acting as Dealer Manager for the Offer. Trilogy has agreed to compensate
SG Cowen for its financial advisory services and to reimburse SG Cowen for its
reasonable out-of-pocket expenses, including those incurred in connection with
SG Cowen's activities as Dealer Manager and including the fees and
disbursements of its legal counsel, and to indemnify SG Cowen against certain
liabilities in connection with the Offer, including certain liabilities under
the federal securities laws.

                                       60
<PAGE>

   Trilogy has retained MacKenzie Partners, Inc. to act as the Information
Agent and American Stock Transfer & Trust Company to act as the Depositary in
connection with the Offer. The Information Agent may contact holders of Shares
by mail, telephone, telegraph and personal interview and may request brokers,
dealers and other nominee stockholders to forward the Offer materials to
beneficial owners. The Information Agent will receive a fee for services as
Information Agent of $10,000 and will be reimbursed for certain out-of-pocket
expenses. The Depositary will receive reasonable and customary compensation for
services relating to the Offer and will be reimbursed for certain out-of-pocket
expenses. Trilogy has also agreed to indemnify the Information Agent and the
Depositary against certain liabilities and expenses in connection with the
Offer, including certain liabilities under the federal securities laws.

   Trilogy will not pay any fees or commissions to any broker or dealer or any
other person for soliciting tenders of Shares pursuant to the Offer (other than
to the Dealer Manager and the Information Agent). Brokers, dealers, commercial
banks, trust companies and other nominees will, upon request, be reimbursed by
Trilogy for customary mailing and handling expenses incurred by them in
forwarding offering materials to their customers.

   The following is an estimate of expenses to be incurred in connection with
the Offer and the Merger. It assumes the Merger will be completed as a Short-
Form Merger.

   13. CERTAIN CONDITIONS TO THE OFFER. Notwithstanding any other provision of
the Offer, and in addition to (and not in limitation of) Trilogy's rights to
extend and amend the Offer at any time in accordance with the terms of the
Merger Agreement, Trilogy shall not be required to accept for payment, purchase
or pay for, subject to any applicable regulations of the SEC, including Rule
14e-1(c) under the Exchange Act, and may

                                       61
<PAGE>

delay the acceptance for payment of or, subject to the restriction referred to
above, the payment for, any tendered Shares (whether or not any Shares
theretofore have been accepted for payment or paid for pursuant to the Offer),
and may amend and terminate the Offer, if, at any time on or after October 25,
2000 and prior to the time of payment for any such Shares, any of the following
events shall occur:

     (a) there shall have been any action taken, or any statute, rule,
  regulation, judgment, order or injunction promulgated, entered, enacted,
  erected, issued or deemed applicable to the Offer or the Merger, or
  Trilogy, pcOrder or any other affiliate of Trilogy, by any governmental or
  regulatory authority, domestic or foreign or any court of competent
  jurisdiction (i) that makes illegal or otherwise directly or indirectly
  restrains or prohibits or makes materially more costly the making of the
  Offer, the acceptance for payment of, or payment for, any Shares by
  Trilogy, Sub or any other affiliate of Trilogy pursuant to the Offer, or
  the consummation of the Merger; (ii) that prohibits or materially limits
  the ownership or operation by pcOrder, Trilogy or any of their subsidiaries
  of all or any material portion of the business or assets of pcOrder,
  Trilogy or any of their subsidiaries; (iii) that imposes limitations on the
  ability of Trilogy, Sub or any other affiliate of Trilogy to exercise full
  rights of ownership of any Shares, including, without limitation, the right
  to vote any Shares acquired by Trilogy pursuant to the Offer or otherwise
  on all matters properly presented to pcOrder's stockholders, including,
  without limitation, the approval and adoption of the Merger Agreement and
  the transactions contemplated by the Merger Agreement; (iv) that compels
  pcOrder, Trilogy or any of Trilogy's subsidiaries to dispose of or hold
  separate all or a material portion of the business or assets of pcOrder; or
  (v) that is reasonably likely to result, directly or indirectly, in any of
  the consequences referred to in clauses (i) through (iv) of this paragraph
  (a);

     (b) any of the representations or warranties of pcOrder set forth in the
  Merger Agreement that are qualified by materiality or the lack of a
  material adverse effect on the business, assets, results of operations or
  financial condition of pcOrder shall not be true and correct, or any of the
  representations and warranties of pcOrder set forth in the Merger Agreement
  that are not so qualified shall not be true and correct in all material
  respects, in each case, as if such representations or warranties were made
  as of such time on or after the date of the Merger Agreement (except to the
  extent such representations and warranties speak as of a specific date or
  period, or as of the date of the Merger Agreement, in which case such
  representations and warranties shall not be so true and correct or true and
  correct in all material respects, as the case may be, as of such specific
  date or as of the date of the Merger Agreement, respectively);

     (c) pcOrder shall have failed to perform in any material respect any
  obligation or to comply in any material respect with any agreement or
  covenant of pcOrder to be performed or complied with by it under the Merger
  Agreement;

     (d) the pcOrder Board, based on the recommendation of the pcOrder
  Special Committee, shall have (including by amendment to the Schedule 14D-9
  filed by pcOrder with the SEC in connection with the Offer) withdrawn or
  modified in a manner adverse to Trilogy or Sub its approval or
  recommendation of the Offer, the Merger or the Merger Agreement or shall
  have resolved to do any of the foregoing;

     (e) pcOrder (acting through the pcOrder Special Committee), Trilogy and
  Sub shall have agreed that Trilogy shall terminate the Offer or postpone
  the acceptance for payment of or payment for shares thereunder;

     (f)(i) any general suspension of trading in securities on any national
  securities exchange or in the over-the-counter market, (ii) the declaration
  of a banking moratorium or any suspension of payments in respect of banks
  by a domestic governmental or regulatory authority, or (iii) any mandatory
  limitation by a governmental or regulatory authority, domestic or foreign,
  that materially and adversely effects the extension of credit by banks or
  other financial institutions; or

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

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

                                       62
<PAGE>

   The foregoing conditions are for the sole benefit of Trilogy, Sub and their
respective affiliates and may be asserted by Trilogy or Sub, in whole or in
part, at any time and from time to time in the sole discretion of Trilogy or
Sub. The failure by Trilogy or Sub at any time to exercise its rights under any
of the foregoing conditions shall not be deemed a waiver of any such rights and
each such right shall be deemed an ongoing right which may be asserted at any
time or from time to time. If the Offer is terminated under any of the
foregoing provisions, all tendered Shares that have not previously been
accepted for payment will be returned to the tendering stockholder.

   14. CERTAIN LEGAL MATTERS.

   GENERAL. Except as described in this Section 14, based on a review of
publicly available filings by pcOrder with the SEC and a review of certain
information furnished by pcOrder to Trilogy and discussions of representatives
of Trilogy with representatives of pcOrder, Trilogy is not aware of any license
or regulatory permit that appears to be material to the business of pcOrder and
that might be adversely affected by Trilogy's acquisition of Shares pursuant to
the Offer, or of any approval or other action by any governmental,
administrative or regulatory agency or authority, domestic or foreign, that
would be required for the acquisition or ownership of Shares by Trilogy
pursuant to the Offer. Should any such approval or other action be required, it
is presently contemplated that such approval or action would be sought, except
as described below under "--State Takeover Laws." While Trilogy does not
currently intend to delay acceptance for payment of Shares tendered pursuant to
the Offer pending the outcome of any such matter, there can be no assurance
that any such approval or other action, if required, would be obtained without
substantial conditions or that adverse consequences would not result to
pcOrder's business or that certain parts of pcOrder's business would not have
to be disposed of in the event that such approval were not obtained or such
other actions were not taken or in order to obtain any such approval or other
action. If certain types of adverse action are taken with respect to the
matters discussed below, Trilogy may decline to accept for payment or pay for
any Shares tendered.

   STATE TAKEOVER LAWS. pcOrder conducts business in a number of states
throughout the United States, some of which have adopted laws and regulations
applicable to offers to acquire shares of corporations that are incorporated or
have substantial assets, stockholders and/or a principal place of business in
such states. In Edgar v. Mite Corp., the Supreme Court of the United States
held that the Illinois Business Takeover Statute, which involved state
securities laws that made the takeover of certain corporations more difficult,
imposed a substantial burden on interstate commerce and was therefore
unconstitutional. In CTS Corp. v. Dynamics Corp. of America, however, the
Supreme Court of the United States held that a state may, as a matter of
corporate law and, in particular, those laws concerning corporate governance,
constitutionally disqualify a potential acquiror from voting on the affairs of
a target corporation without prior approval of the remaining stockholders,
provided that such laws were applicable only under certain conditions, in
particular, that the corporation has a substantial number of stockholders in
and is incorporated under the laws of such state. Subsequently, in TLX
Acquisition Corp. v. Telex Corp., a federal district court in Oklahoma ruled
that the Oklahoma statutes were unconstitutional insofar as they applied to
corporations incorporated outside Oklahoma in that they would subject such
corporations to inconsistent regulations. Similarly, in Tyson Foods, Inc. v.
McReynolds, a federal district court in Tennessee ruled that four Tennessee
takeover statutes were unconstitutional as applied to corporations incorporated
outside Tennessee. This decision was affirmed by the United States Court of
Appeals for the Sixth Circuit.

   Trilogy has not determined whether any of these state takeover laws and
regulations will by their terms apply to the Offer or the Merger, and, except
as set forth above, Trilogy has not presently sought to comply with any state
takeover statute or regulation. Trilogy reserves the right to challenge the
applicability or validity of any state law or regulation purporting to apply to
the Offer or the Merger, and neither anything in this Offer to Purchase nor any
action taken in connection herewith is intended as a waiver of such right. In
the event it is asserted that one or more state takeover statutes is applicable
to the Offer or the Merger and an appropriate court does not determine that
such statute is inapplicable or invalid as applied to the Offer or the Merger,
Trilogy might be required to file certain information with, or to receive
approval from, the relevant state authorities, and Trilogy might be unable to
accept for payment or pay for Shares tendered pursuant to the Offer,

                                       63
<PAGE>

or be delayed in consummating the Offer. In addition, if enjoined, Trilogy
might be unable to accept for payment any Shares tendered pursuant to the
Offer, or be delayed in continuing or consummating the Offer and the Merger. In
such case, Trilogy may not be obligated to accept for payment any Shares
tendered. See "--Section 13. Certain Conditions to the Offer."

   pcOrder is incorporated under the laws of the State of Delaware. In general,
Section 203 of the DGCL ("Section 203") prevents an "interested stockholder"
(including a person who owns or has the right to acquire 15% or more of the
corporation's outstanding voting stock) from engaging in a "business
combination" (defined to include mergers and certain other actions) with a
Delaware corporation for a period of three years following the date such person
became an interested stockholder. The restrictions contained in Section 203 do
not apply to Trilogy as an interested stockholder of pcOrder because Trilogy
became an interested stockholder at a time when the restrictions contained in
Section 203 did not apply to pcOrder, and, under the terms of Section 203, the
restrictions in Section 203 do not apply in that circumstance.

   ANTITRUST. Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
and the rules that have been promulgated thereunder by the Federal Trade
Commission ("FTC"), certain acquisition transactions may not be consummated
unless certain information has been furnished to the Antitrust Division of the
Department of Justice (the "Antitrust Division") and the FTC and certain
waiting period requirements have been satisfied. The purchase of Shares
pursuant to the Offer is not subject to such requirements because Trilogy
currently owns in excess of 50% of pcOrder's issued and outstanding capital
stock.

   The Antitrust Division and the FTC scrutinize the legality under the
antitrust laws of transactions such as the acquisition of Shares by Trilogy
pursuant to the Offer. At any time before or after the consummation of any such
transactions, the Antitrust Division or the FTC could take such action under
the antitrust laws of the United States as it deems necessary or desirable in
the public interest, including seeking to enjoin the purchase of Shares
pursuant to the Offer or seeking divestiture of the Shares so acquired or
divestiture of substantial assets of Trilogy or pcOrder. Private parties
(including individual States) may also bring legal actions under the antitrust
laws of the United States. Trilogy does not believe that the consummation of
the Offer will result in a violation of any applicable antitrust laws. However,
there can be no assurance that a challenge to the Offer on antitrust grounds
will not be made, or if such a challenge is made, what the result will be.

   LITIGATION. For a description of certain litigation challenging the Offer
and the Merger, see "Special Factors--Certain Litigation."

   15. MISCELLANEOUS. The Offer is being made to all holders of Shares. Trilogy
is not aware of any jurisdiction where the making of the Offer is prohibited by
administrative or judicial action pursuant to any valid state statute. If
Trilogy becomes aware of any valid state statute prohibiting the making of the
Offer or the acceptance of Shares pursuant thereto, Trilogy will make a good
faith effort to comply with any such state statute or seek to have such statute
declared inapplicable to the Offer. If, after such good faith effort, Trilogy
cannot comply with any such state statute, the Offer will not be made to (nor
will tenders be accepted from or on behalf of) the holders of Shares in such
state. In any jurisdiction where the securities, blue sky or other laws require
the Offer to be made by a licensed broker or dealer, the Offer will be deemed
to be made on behalf of Trilogy by one or more registered brokers or dealers
licensed under the laws of such jurisdiction.

   NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
REPRESENTATION ON BEHALF OF TRILOGY NOT CONTAINED IN THIS OFFER TO PURCHASE OR
IN THE RELATED LETTER OF TRANSMITTAL AND, IF GIVEN OR MADE, SUCH INFORMATION OR
REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED.

   Trilogy and Sub have filed with the SEC an Offer Statement on Schedule TO,
together with all exhibits thereto, pursuant to Regulation M-A under the
Exchange Act, furnishing certain additional information with respect to the
Offer. pcOrder has joined in the filing for purposes of including the
information required by Schedule 13E-3 (applicable to "going private
transactions"). In addition, pcOrder has filed a Solicitation/Recommendation
Statement on Schedule 14D-9, together with all exhibits thereto, pursuant to
Rule 14d-9 of the Exchange Act setting forth its recommendation with respect to
the Offer and the reasons for such recommendation, and furnishing certain
additional related information. Such filings and any amendments thereto,
including exhibits, may be inspected and copies may be obtained from the
offices of the SEC in the manner set forth in "--Section 7. Certain Information
Concerning pcOrder" (except that they will not be available at the regional
offices of the SEC).

contributions. pcOrder incurs insignificant administrative costs relating to
the plan.

                          AGREEMENT AND PLAN OF MERGER

   AGREEMENT AND PLAN OF MERGER (this "AGREEMENT"), dated as of October 25,
2000, by and among Trilogy Software, Inc., a Delaware corporation ("PARENT"),
POI Acquisition Corp., Inc., a Delaware corporation and a wholly owned
subsidiary of Parent ("SUB"), and pcOrder.com, Inc., a Delaware corporation
(the "COMPANY").

   WHEREAS, the Parent beneficially owns 100% of the Class B common stock, par
value $0.01 per share, of the Company (the "CLASS B COMMON STOCK"), which, on
an as-converted basis, represents approximately 61% of the outstanding shares
of Class A common stock, par value $0.01 per share, of the Company ("CLASS A
COMMON STOCK") (such shares of Class A Common Stock being hereafter referred to
as the "SHARES" and such Class A Common Stock being hereafter referred to,
collectively with the Class B Common Stock, as the "COMPANY COMMON STOCK"); and

   WHEREAS, it is proposed that Parent shall commence a tender offer (the
"TENDER OFFER") to acquire any and all of the outstanding Shares for an amount
equal to $6.375 per Share (such amount, or any greater amount per Share paid
pursuant to the Tender Offer, being hereinafter referred to as the "OFFER
PRICE"), net to the seller in cash, upon the terms and subject to the
conditions provided herein; and

   WHEREAS, it is proposed that, subject to and following the consummation of
the Tender Offer, Sub shall be merged with and into the Company, with the
Company as the surviving corporation, and in such merger all outstanding Shares
(with certain exceptions specified herein) shall be converted into the right to
receive an amount in cash equal to the Offer Price (the "MERGER"); and

   WHEREAS, the Board of Directors of the Company, based on the unanimous
recommendation of the special committee of independent directors of the Board
of Directors of the Company (the "SPECIAL COMMITTEE"), has: (i) determined that
each of the Tender Offer and the Merger is fair to and in the best interests of
the stockholders of the Company (other than Parent, Sub or any other affiliate
of Parent excluding the Company (the "UNAFFILIATED STOCKHOLDERS")); (ii)
approved this Agreement and the transactions contemplated hereby, including,
without limitation the Tender Offer and the Merger; and (iii) resolved to
recommend that the Company's stockholders accept the Tender Offer, tender their
Shares pursuant thereto and approve and adopt this Agreement and the Merger,
subject to the terms and conditions set forth herein;

   NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth in this
Agreement, Parent, Sub and the Company hereby agree as follows:

                                   ARTICLE I

                                THE TENDER OFFER

   Section 1.01 THE TENDER OFFER. The Tender Offer. (a) Provided that none of
the events set forth in Annex A hereto shall have occurred or be existing, as
soon as practicable but in no event (unless otherwise agreed by the Company
acting through the Special Committee) later than the ninth business day
following the date of this Agreement, Parent shall commence the Tender Offer.
The initial expiration date of the Tender Offer shall be the twentieth business
day from and after the date the Tender Offer is commenced (the "INITIAL
EXPIRATION DATE"). The obligation of Parent to commence the Tender Offer and to
accept for payment and pay for Shares tendered pursuant to the Tender Offer
shall be subject only to the conditions set forth in Annex A hereto, any of
which conditions may be waived by Parent in its sole discretion. Parent
expressly reserves the right to amend or make changes to the terms and
conditions of the Tender Offer; provided, however, that, without the prior
written consent of the Company (expressed in a resolution adopted by both the
Special Committee and the Company's Board of Directors), Parent shall not (i)
decrease the Offer Price or change the form of consideration to be paid in the
Tender Offer, (ii) impose any additional conditions to the Tender Offer from
those set forth in Annex A hereto, (iii) reduce the number of Shares subject to
the Tender Offer, or (iv)

                                      A-1
<PAGE>

otherwise amend the Tender Offer in a manner that would adversely affect the
holders of Shares. The Company agrees that no Shares held by the Company will
be tendered pursuant to the Tender Offer. Notwithstanding anything in this
Agreement to the contrary, without the consent of the Company, Parent shall
have the right to extend the Tender Offer beyond the Initial Expiration Date in
the following events: (i) from time to time if, at the Initial Expiration Date
(or extended expiration date of the Tender Offer, if applicable), any of the
conditions to the Tender Offer shall not have been satisfied or waived; (ii)
for any period required by any rule, regulation, interpretation or position of
the Securities and Exchange Commission (the "SEC") or the staff thereof
applicable to the Tender Offer or any period required by applicable law; or
(iii) pursuant to an amendment to the Tender Offer providing for a "subsequent
offering period" not to exceed twenty business days to the extent permitted
under, and in compliance with, Rule 14d-11 under the Securities Exchange Act of
1934, as amended (the "EXCHANGE ACT"). In addition, if at any scheduled
expiration date of the Tender Offer any of the conditions of the Tender Offer
have not been satisfied or waived by Parent but are reasonably capable of being
satisfied, Parent shall extend the Tender Offer for ten calendar days from the
then-scheduled expiration date of the Tender Offer; provided that Parent shall
not be obligated to extend the Tender Offer pursuant to this sentence more than
once. Following the satisfaction or waiver of the conditions to the Tender
Offer, Parent shall accept for payment, in accordance with the terms of the
Tender Offer, all Shares validly tendered pursuant to the Tender Offer and not
withdrawn as soon as it is permitted to do so pursuant to applicable law.

   (b) Parent shall file with the SEC on the date that the Tender Offer is
commenced (i) a Tender Offer Statement on Schedule TO (together with any
supplements or amendments thereto, the "SCHEDULE TO"), which will contain,
among other things, the offer to purchase, form of the related letter of
transmittal and all other required ancillary documents (together with any
supplements or amendments thereto, the "TENDER OFFER DOCUMENTS"), and (ii)
together with the Company, a Rule 13e-3 Transaction Statement on Schedule 13E-3
with respect to the Tender Offer (the "13E-3 TRANSACTION STATEMENT"), which
shall be filed as a part of the Schedule TO. The Tender Offer Documents shall
comply in all material respects with the provisions of applicable federal
securities laws and, on the date filed with the SEC and on the date first
published, sent or given to the Company's stockholders, shall not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading, except
that no representation is made by either Parent or the Company, as the case may
be, with respect to information supplied by the other party in writing for
inclusion in the Tender Offer Documents. Parent further agrees to take all
steps necessary to cause the Tender Offer Documents to be filed with the SEC
and to be disseminated to holders of Shares, in each case as and to the extent
required by applicable federal securities laws. Each of Parent and the Company
agrees promptly to correct any information provided by it for use in the Tender
Offer Documents if and to the extent that it shall have become false and
misleading in any material respect and Parent further agrees to take all steps
necessary to cause the Tender Offer Documents as so corrected to be filed with
the SEC and to be disseminated to holders of Shares, in each case as and to the
extent required by applicable federal securities laws. The Company and its
counsel, and the Special Committee and its counsel, shall be given the
opportunity to review and comment on the initial Schedule TO before it is filed
with the SEC. In addition, Parent agrees to provide the Company and its
counsel, and the Special Committee and its counsel, with any comments or other
communications that Parent or its counsel may receive from time to time from
the SEC or its staff with respect to the Tender Offer Documents promptly after
the receipt of such comments or other communications and to consult with the
Company and its counsel, and the Special Committee and its counsel, prior to
responding to any such comments.

   (c) Notwithstanding any other provision of this Agreement, it shall be a
condition to Parent's right to extend the Tender Offer pursuant to clause (iii)
of Section 1.01(a) that, in connection with such extension, Parent waives, with
respect to all Shares validly tendered during the subsequent offering period
referred to in said clause (iii), all conditions of the Tender Offer.

   Section 1.02 COMPANY ACTION. The Company hereby approves of and consents to
the Tender Offer. Concurrently with the filing of the Schedule TO, the Company
shall file with the SEC and mail to the holders

                                      A-2
<PAGE>

of Shares a Solicitation/Recommendation Statement on Schedule 14D-9 (together
with any supplements or amendments thereto, the "SCHEDULE 14D-9"). The Schedule
14D-9 will set forth, and the Company hereby represents to Parent, that (a)
each of the Special Committee and the Board of Directors of the Company, at
meetings duly held, has made the determination and adopted the resolutions
referred to in the fourth recital to this Agreement; and (b) Dain Rauscher
Wessels, the financial advisor to the Special Committee ("DRW"), has delivered
to the Special Committee and the Company's Board of Directors its written
opinion that the consideration to be received by the Unaffiliated Stockholders
is fair to such stockholders from a financial point of view. The Schedule 14D-9
will comply in all material respects with the provisions of applicable federal
securities laws, will contain the recommendation referred to in the fourth
recital to this Agreement and, on the date filed with the SEC and on the date
first published, sent or given to the Company's stockholders, shall not contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading, except that no representation is made by either the Company, on the
one hand, or either of Parent and Sub, on the other hand, as the case may be,
with respect to information supplied by the other party in writing for
inclusion in the Schedule 14D-9. The Company further agrees to take all steps
necessary to cause the Schedule 14D-9 to be filed with the SEC and to be
disseminated to holders of the Shares, in each case as and to the extent
required by applicable federal securities laws. Each of the Company, on the one
hand, and Parent and Sub, on the other hand, agrees promptly to correct any
information provided by it for use in the Schedule 14D-9 if and to the extent
that it shall have become false and misleading in any material respect and the
Company further agrees to take all steps necessary to cause the Schedule 14D-9
as so corrected to be filed with the SEC and to be disseminated to holders of
the Shares, in each case as and to the extent required by applicable federal
securities laws. Parent and its counsel shall be given a reasonable opportunity
to review and comment on the initial Schedule 14D-9 before it is filed with the
SEC. In addition, the Company agrees to provide Parent, Sub and their counsel
with any comments or other communications 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 receipt of such comments or other
communications and to consult with Parent and its counsel prior to responding
to any such comments.

   Section 1.03 STOCKHOLDER LISTS. In connection with the Tender Offer, the
Company shall promptly furnish Parent with mailing labels, security position
listings of Shares held in stock depositories and any available listing or
computer file containing the names and addresses of the record holders of
Shares, each as of the most recent practicable date, and shall promptly furnish
Parent with such additional information, including updated lists of
stockholders, mailing labels and lists of securities positions and such other
information and assistance as Parent or its agents may reasonably request in
connection with communicating to the record and beneficial holders of Shares
with respect to the Tender Offer and the Merger.

                                   ARTICLE II

shall thereupon cease, (b) the Company shall be the surviving corporation in
the Merger (the "SURVIVING CORPORATION") and shall continue to be governed by

<PAGE>

by making any related filings required under the Delaware General Corporation
Law ("DGCL") in connection with the Merger. The Merger shall become effective

parties hereto and as is specified in the Certificate of Merger (the "EFFECTIVE

Austin, Texas 78731, or such other place as the parties shall agree, for the
purposes of confirming the satisfaction or waiver, as the case may be, of the

   Section 2.04 CERTIFICATE OF INCORPORATION AND BYLAWS. Subject to Section
6.03 hereof: (a) at the Effective Time, the Certificate of Incorporation of the
Company in effect immediately prior thereto, shall remain the Certificate of
Incorporation of the Surviving Corporation until amended in accordance with
applicable law; and (b) the Bylaws of the Company in effect immediately prior
thereto shall be amended and restated to read in their entirety identically
with the Bylaws of Sub as then in effect, except that they shall retain the
Company's current name.

   Section 2.05 DIRECTORS. The directors of Sub immediately prior to the
Effective Time shall be the initial directors of the Surviving Corporation
until their respective successors are duly elected or appointed and qualified

holder of Shares:

     (a) Each share of Company Common Stock issued and outstanding

  shall automatically be canceled and retired and shall cease to exist, and
  each certificate previously evidencing any such share (other than Shares to
  be canceled pursuant to clause (b) below and any Dissenting Shares (as
  hereinafter defined)) shall thereafter represent only the right to receive,
  upon the surrender of such certificate in accordance with the provisions of
  Section 3.02, an amount in cash per Share equal to the Offer Price (the
  "MERGER CONSIDERATION"), without interest. The holders of such certificates
  previously evidencing such shares of Company Common Stock outstanding
  immediately prior to the Effective Time shall cease to have any rights with
  respect to such shares of Company Common Stock except as otherwise provided
  herein or by law.

     (b) Each share of Company Common Stock (i) held in the treasury of the
  Company or (ii) owned by Parent or Sub shall automatically be canceled,
  retired and cease to exist without any conversion thereof and no payment
  shall be made with respect thereto.

     (c) Each share of common stock, par value $0.01 per share ("SUB COMMON
  STOCK"), of Sub outstanding immediately prior to the Effective Time shall
  be converted into and become one share of common stock of the Surviving
  Corporation and shall constitute the only outstanding shares of capital
  stock of the Surviving Corporation.

   Section 2.08 OPTIONS AND ESPP.

   (a) Following the execution of this Agreement, the Company shall use
commercially reasonable efforts to cause all holders of options to purchase
Class A Common Stock granted under the Company's 1996 Stock

                                      A-4
<PAGE>

Option Plan and 1999 Stock Incentive Plan, each as amended (collectively, the
"STOCK OPTION PLANS"), to execute prior to the Effective Time an Option
Relinquishment and Release Agreement (herein so called) in a form agreed upon
by Parent and the Company. As soon as practicable after the Effective Time,
Parent and the Surviving Corporation shall cause the Paying Agent (as
hereinafter defined) to pay to such holders who have previously delivered an
Option Relinquishment and Release Agreement a cash amount equal to the product
of (i) the number of shares of Class A Common Stock subject to such option
(irrespective of whether such option is then exercisable) and (ii) the amount
by which the Merger Consideration exceeds the exercise or strike price per
share of Class A Common Stock subject to such option immediately prior to the
Effective Time, less any required withholding taxes. In the event that an
option holder fails to deliver an Option Relinquishment and Release Agreement
prior to the Effective Time and remains employed by the Company at all times
through and including the Effective Time, such holder's options (the
"OUTSTANDING OPTIONS") shall, in accordance with the terms and conditions of
the governing Stock Option Plan and the holder's stock option agreement(s), be
converted without any action on the part of the holder thereof into the right
to receive an amount equal to the Merger Consideration, upon the exercise of
such holder's options in accordance with, and within the time period prescribed
by, the applicable Stock Option Plan and the holder's stock option
agreement(s). In the event that an option holder voluntarily terminates such
option holder's employment with the Company prior to the Effective Time,
whether or not such option holder has executed an Option Relinquishment and
Release Agreement, such option holder's options shall be treated, in connection
with the consummation of the Merger, in accordance with the provisions of the
applicable Stock Option Plan without regard to the provisions of this Section
2.08(a). The Surviving Corporation shall pay, or cause the Paying Agent to pay,
to each holder of Outstanding Options the Merger Consideration, less any
required withholding taxes, as promptly as practicable after receiving a valid
exercise of an Outstanding Option by the holder thereof.

   (b) Following the execution of this Agreement, the Company shall use
commercially reasonable efforts to cause all holders of options to purchase
Class A Common Stock granted under the Company's 2000 Nonstatutory Stock Option
Plan (the "2000 PLAN") to execute prior to the Effective Time an Option
Relinquishment and Release Agreement in a form agreed upon by Parent and the
Company. As soon as practicable after the Effective Time, Parent and the
Surviving Corporation shall cause the Paying Agent to pay to such holders who
have previously delivered an Option Relinquishment and Release Agreement and
remained employed by the Company at all times through and including the
Effective Time a cash amount equal to the product of (i) the number of shares
of Class A Common Stock subject to such option (irrespective of whether such
option is then exercisable) and (ii) the amount by which the Merger
Consideration exceeds the exercise or strike price per share of Class A Common
Stock subject to such option immediately prior to the Effective Time, less any
required withholding taxes. In the event that an option holder voluntarily
terminates such option holder's employment with the Company prior to the
Effective Time, such option holder's options shall be treated, in connection
with the consummation of the Merger, in accordance with the provisions of the
applicable 2000 Plan without regard to the provisions of this Section 2.08(b).
In the event that an option holder fails to deliver an Option Relinquishment
and Release Agreement prior to the Effective Time, such holder's rights shall
be controlled by the terms of the 2000 Plan.

   (c) The Company's Board of Director has resolved that, effective as of
November 1, 2000, the Company's Employee Stock Purchase Plan (the "ESPP") shall
terminate.

   Section 2.09 MERGER WITHOUT STOCKHOLDERS' MEETING. If, as a result of the
purchase of Shares pursuant to the Tender Offer and compliance with the terms
of this Section 2.09, Parent owns in the aggregate at least 90% of the Shares
then outstanding upon completion of the Tender Offer and continues to hold at
least 90% of the outstanding Class B Common Stock, the parties hereto agree to
take all necessary and appropriate action to cause the Merger to become
effective as soon as practicable after the satisfaction or waiver of the
conditions to the Merger set forth in Article VII without a meeting of
stockholders of the Company, in accordance with Section 253 of the DGCL (a
"SHORT-FORM MERGER"). In connection therewith, if following the purchase of
Shares pursuant to the Tender Offer, Parent owns in the aggregate less than 90%
of the Shares then outstanding, Parent agrees to convert such number of shares
of Class B Common Stock into Class A Common Stock to the

                                      A-5
<PAGE>

extent that, after giving effect to such conversion, Parent would own in the
aggregate the number of Shares necessary to effect a Short-Form Merger.

   Section 2.10 STOCKHOLDERS' MEETING OR ACTION BY CONSENT. (a) If required by
applicable law in order to consummate the Merger, the Company acting through
its Board of Directors shall, in accordance with applicable law:

     (i) duly call, give notice of, convene and hold a special meeting of its
  stockholders (the "SPECIAL MEETING") as soon as practicable following the
  acceptance for payment and purchase of Shares by Parent pursuant to the
  Tender Offer to consider and vote upon the approval and adoption of this
  Agreement and the Merger;

     (ii) prepare and file with the SEC a preliminary proxy statement or
  information statement, as appropriate, relating to this Agreement and the
  Merger and use its best efforts (A) after consultation with Parent and Sub,
  to respond promptly to any comments made by the staff of the SEC with
  respect to such preliminary proxy statement or information statement and
  cause a definitive proxy or information statement (together with any
  amendments or supplements thereto, and including the related amendment to
  the 13e-3 Transaction Statement, the ("PROXY STATEMENT") to be mailed to
  its stockholders at the earliest practicable time, and (B) to obtain the
  necessary approvals of this Agreement and the Merger by its stockholders;
  and

     (iii) include in the Proxy Statement the recommendations of the Special
  Committee and the Company's Board of Directors that the stockholders of the
  Company vote in favor of the approval and adoption of this Agreement and
  the Merger, except to the extent that the Board of Directors of the
  Company, based on the recommendation of the Special Committee, shall have
  determined in good faith, having received (in the case of the Special
  Committee) the advice of its outside counsel, that such recommendation
  would violate its fiduciary duties under applicable law.

   (b) Parent and Sub will provide the Company with the information concerning
Parent, Sub and their subsidiaries and affiliates required under the Exchange
Act to be included in the Proxy Statement. Parent, will vote all of its shares
of Sub Common Stock in favor of the approval and adoption of this Agreement and
the Merger, if necessary to effect the Merger. In addition, if a vote of the
stockholders of the Company is necessary to effect the Merger, Parent will
vote, or cause to be voted, all shares of Company Common Stock owned by it and
its subsidiaries in favor of the approval and adoption of this Agreement and
the Merger.

   (c) If the Merger cannot be effected as a Short-Form Merger, Parent may
elect (in lieu of the Company submitting this Agreement and the Merger to a
vote of its stockholders at the Special Meeting) to execute a written consent
approving and adopting this Agreement and the Merger, consistent with the
applicable requirements of Delaware law and the federal securities laws.

                                  ARTICLE III

                     DISSENTING SHARES; PAYMENT FOR SHARES

   Section 3.01 DISSENTING SHARES. Notwithstanding anything in this Agreement
to the contrary, Shares outstanding immediately prior to the Effective Time
that are held by stockholders (i) who shall have neither voted for approval and
adoption of this Agreement and the Merger nor consented thereto in writing and
(ii) who shall be entitled to and shall have demanded properly in writing
appraisal for such Shares in accordance with Section 262 of the DGCL
("DISSENTING SHARES"), shall not be converted into the right to receive the
Merger Consideration at or after the Effective Time unless and until the holder
of such Shares fails to perfect, withdraws, waives or otherwise loses such
holder's right to appraisal. If a holder of Dissenting Shares shall withdraw
(in accordance with Section 262(k) of the DGCL) his or her demand for such
appraisal or shall become ineligible for such appraisal, then, as of the
Effective Time or the occurrence of such event, whichever last occurs, such
holder's Dissenting Shares shall cease to be Dissenting Shares and shall be
converted into and

                                      A-6
<PAGE>

represent the right to receive the Merger Consideration, without interest
thereon. The Company shall give Parent (a) prompt notice of any written demands
for appraisal, withdrawals of demands for appraisal and any other instruments
served pursuant to Section 262 of the DGCL and received by the Company and (b)
the opportunity to direct all negotiations and proceedings with respect to
demands for appraisal. The Company shall not, except with the prior written
consent of Parent, make any payment with respect to any demands for payment of
fair value or offer to settle or settle any such demands.

   Section 3.02 EXCHANGE OF CERTIFICATES AND CASH. (a) On or before the date of
Closing, Parent shall enter into an agreement, in form and substance reasonably
satisfactory to the Company (acting through the Special Committee), providing
for the matters set forth in this Section 3.02 and Section 2.08 (the "PAYING
AGENT AGREEMENT") with a bank or trust company selected by Parent (the "PAYING
AGENT"), authorizing such Paying Agent to act as Paying Agent in connection
with the Merger. Immediately prior to the Effective Time, Parent shall deposit
or shall cause to be deposited with or for the account of the Paying Agent, for
the benefit of the holders of shares of Company Common Stock (other than
Dissenting Shares and shares to be canceled pursuant to Section 2.07(b)), an
amount in cash equal to the aggregate Merger Consideration payable pursuant to
Section 2.07(a) and Section 2.08 (such cash funds are hereafter referred to as
the "PAYMENT FUND").

   (b) As soon as reasonably practicable after the Effective Time, Parent will
instruct the Paying Agent to mail to each holder of record of a certificate or
certificates that immediately prior to the Effective Time evidenced outstanding
shares of Company Common Stock (other than Dissenting Shares and shares to be
canceled pursuant to Section 2.07(b)) (the "CERTIFICATES"), (i) a form letter
of transmittal (which shall specify that delivery shall be effected, and risk
of loss and title to the Certificates shall pass, only upon proper delivery of
the Certificates to the Paying Agent and shall be in such form and have such
other provisions as Parent and the Company may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for 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 a letter of transmittal, duly executed, and such other
customary documents as may be required pursuant to such instructions
(collectively, the "TRANSMITTAL DOCUMENTS"), the holder of such Certificate
shall be entitled to receive in exchange therefor the Merger Consideration for
each share of Company Common Stock formerly represented by such Certificate,
without any interest thereon, less any required withholding of taxes, and the
Certificate so surrendered shall thereupon be canceled. In the event of a
transfer of ownership of shares of Company Common Stock that is not registered
in the transfer records of the Company, the Merger Consideration may be issued
and paid in accordance with this Article III to the transferee of such shares
if the Certificate evidencing such shares of Company Common Stock is presented
to the Paying Agent and is properly endorsed or otherwise in proper form for
transfer. In such event, the signature on the Certificate or any related stock
power must be properly guaranteed and the person requesting payment of the
Merger Consideration must either pay any transfer or other taxes required by
reason of the payment to a person other than the registered holder of the
Certificate so surrendered or establish to the Surviving Corporation that such
tax has been paid or is not applicable. The Merger Consideration will be
delivered by the Paying Agent as promptly as practicable following surrender of
a Certificate and the related Transmittal Documents. Cash payments may be made
by check unless otherwise required by a depositary institution in connection
with the book-entry delivery of securities. No interest will be payable on such
Merger Consideration. Until surrendered in accordance with this Section 3.02,
each Certificate shall be deemed at any time after the Effective Time to
evidence only the right to receive, upon such surrender, the Merger
Consideration for each share of Company Common Stock formerly represented by
such Certificate. The Payment Fund shall not be used for any purpose other than
as set forth in this Article III. Any interest, dividends or other income
earned on the investment of cash held in the Payment Fund shall be for the
account of the Surviving Corporation.

   (c) Any portion of the Payment Fund (including the proceeds of any
investments thereof) which remains undistributed to the holders of Company
Common Stock for six months following the Effective Time shall be delivered by
the Paying Agent to the Surviving Corporation, upon demand. Any holders of
Company Common Stock who have not theretofore complied with this Article III
shall thereafter look only to the Surviving Corporation for payment of the
Merger Consideration.

                                      A-7
<PAGE>

   (d) None of the Surviving Corporation, Parent, Sub, the Company or the
Paying Agent shall be liable to any holder of shares of Company Common Stock
for any cash delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

   (e) The Surviving Corporation and the Paying Agent shall be entitled to
deduct and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of shares of Company Common Stock such amounts as the
Surviving Corporation or the Paying Agent is required to deduct and withhold
with respect to the making of such payment under the United States Internal
Revenue Code of 1986, as amended (the "CODE"), or any provision of state, local
or foreign tax law. To the extent that amounts are so withheld by the Surviving
Corporation or the Paying Agent, such withheld amounts shall be treated for all
purposes of this Agreement as having been paid to the holder of the shares of
Company Common Stock in respect of which such deduction and withholding was
made by the Surviving Corporation or the Paying Agent.

   (f) In the event any Certificates evidencing shares of Company Common Stock
shall have been lost, stolen or destroyed, the holder of such lost, stolen or
destroyed Certificate(s) shall execute an affidavit of that fact upon request.
The holder of any such lost, stolen or destroyed Certificate(s) shall also
deliver a reasonable indemnity against any claim that may be made against
Parent, Sub or the Paying Agent with respect to the Certificate(s) alleged to
have been lost, stolen or destroyed. The affidavit and any indemnity which may
be required hereunder shall be delivered to the Paying Agent, who shall be
responsible for making payment for such lost, stolen or destroyed
Certificates(s) pursuant to the terms hereof.

   Section 3.03 STOCK TRANSFER BOOKS. At the Effective Time, the stock transfer
books of the Company shall be closed, and there shall be no further
registration of transfers of shares of Company Common Stock thereafter on the
records of the Company (other than transfers, consistent with standard
settlement procedures, to reflect transactions in the Shares that occurred in
the open market, or pursuant to the exercise of stock options, prior to the
Effective Time). Any Certificates presented to the Paying Agent or the
Surviving Corporation for any reason at or after the Effective Time shall be
canceled and exchanged for the Merger Consideration pursuant to the terms in
this Article III.

transactions contemplated hereby.

   Section 4.05 SEC FILINGS AND FINANCIAL STATEMENTS. The Company has
heretofore timely filed all forms, reports, statements, schedules and other
materials with the SEC required to be filed pursuant to the Exchange Act or
other federal securities laws since February 25, 1999 (the "SEC REPORTS"). As

incorporated by reference therein) complied in all material respects with all
applicable requirements of the Exchange Act and other federal securities laws
and to the knowledge of the Company, did not contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein

respective dates, the financial position and the results of operations and cash
flows of the Company as at the dates thereof or for the periods presented
therein.

including the date of this Agreement, the Company has not (a) conducted its
business other than in the ordinary and usual course of business consistent
with past practice or (b) suffered any change in its business, financial
condition, results of operations, assets or liabilities which, in the
aggregate, has had or is reasonably likely to have a Company Material Adverse
Effect.

   Section 4.07 NO UNDISCLOSED LIABILITIES. Except (a) as disclosed in the SEC
Reports filed prior to the date hereof, (b) as disclosed in Section 4.07 of the
Disclosure Schedule, (c) for liabilities incurred by the Company in the
ordinary course of business consistent with past practice and (d) for
liabilities incurred in connection with the transactions contemplated by this
Agreement, to the best knowledge of the Company, the Company has not incurred
any liabilities or obligations (whether absolute, accrued, contingent or
otherwise) which, individually or in the aggregate, would be reasonably likely
to have a Company Material Adverse Effect.

   Section 4.08 PROXY STATEMENT. In addition to the Company's representations
and warranties contained in Section 1.02, none of the information supplied by
the Company for inclusion in the Proxy Statement or related materials, at the
time such Proxy Statement or any amendments or supplements thereto are filed

                                      A-10
<PAGE>

and at the time of the first mailing and at the time of the Special Meeting,
shall contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements made therein, in light of the circumstances under which they were
made, not misleading.

   Section 4.09 BROKERS. No broker, finder or investment banker (other than
DRW) is entitled to any brokerage, finder's or other fee or commission in

correct copy of all agreements between the Company and DRW pursuant to which
such firm would be entitled to any payment relating to the transactions
contemplated hereby.

   Section 4.10 COMPLIANCE WITH APPLICABLE LAW. Except as disclosed in Section
4.10 of the Disclosure Schedule, the Company holds all material licenses,
franchises, permits and authorizations necessary for the lawful conduct of its
business as presently conducted and is in compliance with the terms thereof,
except where the failure to hold such license, franchise, permit or
authorization or such noncompliance would not, when aggregated with all other
such failures or noncompliance, reasonably be expected to have a Company
Material Adverse Effect, and the Company does not know of, or has not received
notice of, any material violations of any applicable law, statute, order,
rule, regulation, policy and/or guideline of any Governmental Entity relating
to the Company, which, in the aggregate, would reasonably be expected to have
a Company Material Adverse Effect.

   Section 4.11 TAX RETURNS AND TAX PAYMENTS. The Company has timely filed all
Tax Returns (as hereinafter defined) required to be filed by it for periods
ending after August 25, 1999, except for such failure that would not result in
a Company Material Adverse Effect. The Company has paid all Taxes (as
hereinafter defined) shown to be due on such Tax Returns filed by it for
periods ending after August 25, 1999, or has provided reserves in its
financial statements for any Taxes that have not been paid, whether or not
shown as being due on any Tax Returns, except for such Taxes which, if unpaid
or unreserved, would not result in a Company Material Adverse Effect. The
Company has not granted any request that remains in effect for waivers of the
time to assess any Taxes. To the Company's knowledge, except as disclosed in
Section 4.11 of the Disclosure Schedule, no claim for unpaid Taxes has been
asserted against the Company in writing by a Tax authority which, if resolved
in a manner unfavorable to the Company would result, individually or in the
aggregate, in a Company Material Adverse Effect. To the Company's knowledge,
there are no liens for Taxes upon the assets of the Company, except for liens
for Taxes not yet due and payable or for Taxes that are being disputed in good
faith by appropriate proceedings and with respect to which adequate reserves
have been taken, that could result in a Company Material Adverse Effect. To
the Company's knowledge, except as disclosed in Section 4.11 of the Disclosure
Schedule, no audit of any Tax Return of the Company is being conducted by a
Tax authority. To the Company's knowledge, except as disclosed in Section 4.11

               REPRESENTATIONS AND WARRANTIES OF PARENT AND SUB

   Parent and Sub hereby jointly and severally represent to the Company as
follows:

   Section 5.01 CORPORATE ORGANIZATION. Each of Parent and Sub is a
corporation duly organized, validly existing and in good standing under the
laws of the State of Delaware. Sub has been formed, as a wholly-owned
subsidiary of Parent, solely for the purpose of effectuating the Merger and,
prior to the Effective Time, will have conducted no business other than as
contemplated by this Agreement.

   Section 5.02 AUTHORITY RELATIVE TO THIS AGREEMENT. Each of Parent and Sub
has all necessary corporate power and authority to execute and deliver this
Agreement, to perform its obligations hereunder and to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement
by Parent and Sub and the consummation by each of them of the transactions
contemplated hereby have been duly and validly authorized by the Boards of
Directors of Parent and Sub, and by Parent as the sole stockholder of Sub, and
no other corporate proceedings on the part of Parent or Sub are necessary to
authorize the execution, delivery and performance of this Agreement by Parent
and Sub or the consummation by Parent and Sub of the transactions contemplated
hereby (other than, with respect to the Merger, the filing and recordation of
the Certificate of Merger as required by the DGCL). This Agreement has been
duly and validly executed and delivered by each of Parent and Sub and,
assuming the due authorization, execution and delivery by the Company,
constitutes a valid and binding obligation of each of Parent and Sub,
enforceable against each of Parent and Sub in accordance with its terms,
subject to (i) bankruptcy, insolvency and moratorium laws and to the laws
affecting creditors' rights generally and (ii) the discretionary nature of
equitable remedies.

   Section 5.03 NO CONFLICT; REQUIRED FILINGS AND CONSENTS. (a) The execution
and delivery of this Agreement by Parent and Sub do not, and the consummation
of the transactions contemplated hereby will not, (i) conflict with or violate
the certificate of incorporation or bylaws of either Parent or Sub, (ii)
conflict with or violate any law, rule, regulation, order, judgment or decree
applicable to either Parent or Sub or by which any of their properties or
assets are bound or affected, or (iii) result in any breach of or constitute a
default (or an event which, with notice, lapse of time or both, would become a
default) under, result in the loss of a material benefit under or give to
others any right of termination, amendment, acceleration, increased payments
or cancellation of, or result in the creation of a lien or other encumbrance
on any properties or assets of either Parent or Sub pursuant to, any note,
bond, mortgage, indenture, contract, agreement, lease, license, permit,
franchise or any other instrument or obligation to which either Parent or Sub
is a party or by which either Parent or Sub or any of their properties or
assets is bound or affected, except in the case of clauses (ii) and (iii), for
any such conflicts, violations, breaches, defaults or other occurrences which
would not, individually or in the aggregate, prevent or materially delay or
impair the performance by each of Parent or Sub of any of its obligations
under this Agreement or the consummation of any of the transactions
contemplated hereby (a "PARENT MATERIAL ADVERSE EFFECT").

   (b) The execution and delivery of this Agreement by Parent and Sub do not,
and the performance of this Agreement and the consummation of the Tender
Offer, the Merger and the other transactions contemplated hereby by Parent and
Sub will not, require any consent, approval, authorization or permit of, or
filing with or notification to, any Governmental Entity, except (i) for (A)
any applicable requirements, if any, of the Exchange Act, the Securities Act,
state securities or blue sky laws, and (B) filing and recordation of
appropriate merger and similar documents as required by the DGCL and (ii)
where the failure to obtain such consents, approvals, authorizations or
permits, or to make such filings or notifications, would not prevent or delay
consummation of

                                     A-12
<PAGE>

the transactions contemplated hereby in any material respect or otherwise
prevent Parent or Sub from performing its obligations under this Agreement in
any material respect, or would not, individually or in the aggregate,
reasonably be expected to have a Parent Material Adverse Effect.

   Section 5.04 BROKERS. No broker, finder or investment banker (other than SG
Cowen Securities Corporation) is entitled to any brokerage, finder's or other
fee or commission in connection with this Agreement, the Tender Offer, the
Merger and the other transactions contemplated hereby based upon arrangements
made by or on behalf of Parent or Sub.

   Section 5.05 PROXY STATEMENT. In addition to Parent's and Sub's
representations and warranties contained in Section 1.01(b), none of the
information supplied by Parent or Sub for inclusion in the Proxy Statement or
related materials at the time such Proxy Statement or any amendments or
supplements thereto are filed with the SEC and at the time of the first mailing
and at the time of the Special Meeting, shall contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements made therein, in light of the
circumstances under which they were made, not misleading.

   Section 5.06 LITIGATION. No action, suit or proceeding is pending or, to the
knowledge of Parent, threatened against Parent or Sub, which, individually or
in the aggregate with any other such action, suit or proceeding, is reasonably
likely to have a Parent Material Adverse Effect.

   Section 5.07 FINANCING. Parent has available to it, without the need to use
any of the Company's cash or cash equivalent assets, the funds necessary for
the completion of the transactions contemplated by this Agreement. If Parent
borrows any funds to finance any of such transactions, none of such borrowings
will be incurred by, or secured, directly or indirectly, by the assets of, the
Company.

   Section 5.08 STOCK OWNERSHIP. (a) At all times from the date the Company's
initial public offering was completed until the date of this Agreement, Parent
has owned, beneficially and of record, shares of Company Common Stock
representing at least 15% of the outstanding voting power of all of the
Company's outstanding voting securities.

   (b) As of the date of this Agreement, Parent owns, beneficially and of
record, all of the outstanding shares of Class B Common Stock and none of the
outstanding Shares.

<PAGE>

  outstanding on October 20, 2000 or (z) the terms of the ESPP as in effect
  on the date hereof; (v) except in the ordinary and usual course of business
  consistent with past practice, sell, pledge, dispose of or encumber any of
  its material assets; (vi) incur any long-term indebtedness for borrowed
  money, issue any debt securities or assume, guarantee or endorse any
  material obligations of any other person; (vii) approve, adopt or amend any

  expiration; or (xv) authorize any of the foregoing, or enter into any
  contract, agreement, commitment or arrangement to do any of the foregoing.

   Section 6.02 NOTIFICATION OF CERTAIN MATTERS. The Company shall give prompt
notice to Parent, and Parent shall give prompt notice to the Company, of the
occurrence, or failure to occur, of any event which occurrence or failure to
occur would be likely to cause (a) any representation or warranty contained in
this Agreement to be untrue or inaccurate in any material respect, or (b) any
material failure of the Company, on the one hand, or Parent or Sub, on the
other hand, as the case may be, to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it under this
Agreement; provided, however, that no such notification shall affect the
representations or warranties of the parties of the conditions to the parties
hereunder.

   Section 6.03 INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE. (a) Parent
and the Company agree that all rights to indemnification and advancement of
expenses now existing in favor of the present or former directors or officers
of the Company as provided in the Company Charter and Bylaws, in effect as of
the date hereof shall, with respect to matters occurring prior to the Effective
Time, survive the Merger and continue in full force and effect after the
Effective Time. To the maximum extent permitted by law, such indemnification
shall be mandatory rather than permissive, and the Company or the Surviving
Corporation, as the case may be, shall advance expenses in connection with such
indemnification. Parent and the Company further agree that all rights to
indemnification now existing in favor of the present or former directors or
officers of the Company in any indemnification agreement between such person
and the Company shall survive the Merger and continue in full force and effect
in accordance with the terms of such agreement.

   (b) Parent shall or the Surviving Corporation shall maintain in effect for
six years from the Effective Time, to the extent available, the current
directors' and officers' liability insurance policies maintained by Parent or
the Company covering those directors and officers of the Company who are
currently covered by such policies with respect to matters occurring prior to
the Effective Time; provided, however, that: (i) Parent or Surviving
Corporation may substitute therefor policies of at least the same coverage
containing terms and conditions that are not less favorable to the
beneficiaries thereof so long as such substitution does not result in gaps or
lapses in coverage; (ii) in no event shall the Parent or the Surviving
Corporation be required to expend in any one year an amount in excess of 150%
of the annual premiums currently paid by the Company for such insurance (in
which event Parent or the Surviving Corporation shall cause to be maintained
directors' and officers' liability insurance that, in Parent's good faith
judgment, provides the maximum coverage available for such maximum premium and
reasonably comparable to the current coverage); and (iii) the Parent may meet
its obligations under this paragraph by covering the above persons under the
Parent's insurance policy or policies on the terms described above.

   (c) In the event that Parent or the Surviving Corporation or any of its
successors or assigns (i) consolidates with or merges into any other person and
shall not be the continuing or surviving corporation or entity of such

                                      A-14
<PAGE>

consolidation or merger or (ii) transfers or conveys all or any substantial
portion of its properties and assets to any person, then, and in each such
case, proper provision shall be made so that the successors and assigns of such
party assume the obligations of such party as contemplated by this Section
6.03.

   Section 6.04 ACCESS AND INFORMATION. The Company shall afford to Parent, Sub
and their representatives such access during normal business hours throughout
the period prior to the Effective Time to the Company's books, records
(including, without limitation, tax return and work papers of the Company's
independent auditors), facilities, personnel and to such other information as
Parent shall reasonably request. All such information shall, to the fullest
extent consistent with applicable law, be subject to the provisions of the
confidentiality agreement between the Company and Parent entered into on
September 28, 2000 (the "CONFIDENTIALITY AGREEMENT").

   Section 6.05 PUBLICITY. None of the Company, Parent or Sub shall issue or
cause the publication of any press release or other public announcement with
respect to this Agreement, the Tender Offer, the Merger or the other
transactions contemplated hereby without prior consultation with the other
parties, except as may be required by law or any listing agreement with a
national securities exchange to which Parent or the Company is a party. Parent
and the Company have heretofore agreed upon the text of the initial press
release to be issued with respect to this Agreement and the transactions
contemplated hereby.

   Section 6.06 COMMERCIALLY REASONABLE EFFORTS. Subject to the terms and
conditions hereof, each of the parties hereto agrees to use its commercially
reasonable efforts to take, or cause to be taken, all actions and to do, or
cause to be done, all things necessary, proper or advisable to consummate and
make effective as promptly as practicable the Tender Offer, the Merger and the
other transactions contemplated by this Agreement, and to cooperate with each
other in connection with the foregoing, including using its reasonable best
efforts to (a) obtain all necessary waivers, consents and approvals from other
parties to material agreements, leases and other contracts, (b) obtain all
necessary consents, approvals and authorizations as are required to be obtained
under any federal, state or foreign law or regulation, (c) lift or rescind any
injunction or restraining order or other order adversely affecting the ability
of the parties to consummate the transactions contemplated hereby, (d) effect

the Merger or the other transactions contemplated this Agreement, and the
Company shall not settle or compromise any such claim, suit or cause of action
without Parent's prior written consent, which shall not be unreasonably
withheld.

   Section 6.07 CONTRIBUTION OF COMPANY COMMON STOCK. Promptly following
consummation of the Offer, Parent shall contribute all shares of Class A Common
Stock and all shares of Class B Common Stock to Sub if necessary to effect the
Merger as a Short-Form Merger.

its financial advisors, attorneys and accountants), (a) initiates contact with,
(b) enters into or participates in any discussions or negotiations with, (c)
discloses, directly or indirectly, any information not customarily disclosed
concerning the business and properties of the Company to or (d) affords any

(iii) the merger of the Company with any person other than Sub or (iv) any
similar transaction, except as contemplated herein. The Company will promptly
notify Parent orally of all the relevant details of any inquiry or proposal
that it receives relating to any such matters.

   Section 6.09 BOARD RECOMMENDATION. Except to the extent that the Board of
Directors of the Company, based on the recommendation of the Special Committee,
shall have determined in good faith, having received

                                      A-15
<PAGE>

(in the case of the Special Committee) the advice of its outside counsel, that
its recommendation of the Tender Offer or the Merger would violate its
fiduciary duties under applicable law, neither the Company's Board of Directors
nor any committee thereof shall withdraw, modify or change, or propose publicly
to withdraw, modify or change, in a manner adverse to the Parent, such Board
recommendation of the Tender Offer or the Merger. Nothing contained in this
Section 6.09 shall prohibit the Company or its Board of Directors from at any
time taking and disclosing to its stockholders a position contemplated by Rule
14e-2 promulgated under the Exchange Act or from making any disclosure to the
Company's stockholders required by applicable law.

date hereof, and the Company represents and warrants that as of the respective
dates thereof, such reports will not contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading. The audited financial statements and the
unaudited interim financial statements included in such reports (including any
related notes and schedules) will fairly present the financial position of the
Company, as of the dates thereof and the results of operations and cash flows
or other information included therein for the periods or as of the date then
ended (except as may be indicated in the notes thereto and subject, in the case
of unaudited interim financial statements, to normal, year-end adjustments), in
each case in accordance with GAAP consistently applied during the periods
involved.

   Section 6.11 DISCLOSURE SCHEDULE SUPPLEMENTS. From time to time after the
date of this Agreement and prior to the Effective Time, the Company will
promptly supplement or amend the Disclosure Schedule with respect to any matter
hereafter arising which, if existing or occurring at or prior to the date of
this Agreement, would have been required to be set forth or described in the
Disclosure Schedule or that is necessary to correct any representation and
warranty of the Company that has been rendered inaccurate thereby in any
material respect. For purposes of determining the accuracy of the
representations and warranties of the Company contained in this Agreement in
order to determine the fulfillment of the condition set forth in paragraph (c)
of Annex A, the Disclosure Schedule shall be deemed to include only that
information contained therein on the date of this Agreement and shall be deemed
to exclude any information contained in any subsequent supplement or amendment
thereto.

   Section 6.12 ROLE OF SPECIAL COMMITTEE. Prior to the earlier to occur of the
Effective Time or the termination of this Agreement pursuant to its terms: (a)
Parent shall not take, or cause to be taken, any action to remove from office,
or impair the authority of, any member of the Special Committee; and (b)
without limiting the effect of any other provision of this Agreement that
confers authority upon the Special Committee with respect to this Agreement,
all of the rights of the Company under this Agreement (including, without
limitations, rights of waiver and enforcement) are, to the fullest extent
permitted by the DGCL, vested exclusively in the Special Committee and shall be
exercised by the Company only with the consent, or at the express direction, of
the Special Committee.

this Agreement, the Board of Directors of the Company shall adopt resolutions
to clarify that the Stock Option Plans permit the treatment of options to

<PAGE>

     (b) No Governmental Entity or federal or state court of competent
  jurisdiction shall have enacted, issued, promulgated, enforced or entered
  any statute, rule, regulation, executive order, decree, injunction or other
  order (whether temporary, preliminary or permanent) that is in effect and
  that materially restricts, prevents or prohibits consummation of the Merger
  or the other transactions contemplated by this Agreement; provided,
  however, that the parties shall use their reasonable best efforts to cause
  any such decree, judgment, injunction or other order to be vacated or
  lifted; and

     (c) Parent shall have purchased Shares pursuant to the Tender Offer.

                                  ARTICLE VIII

   Section 8.01 TERMINATION. This Agreement may be terminated and the
transactions contemplated herein may be abandoned at any time prior to the
Effective Time, whether prior to or after approval by the stockholders of the
Company:

     (a) by mutual written consent of the Board of Directors of the Company
  on behalf of the Company (as agreed to by the Special Committee) and Parent
  and Sub;

     (b) by either Parent or the Company (acting through the Special
  Committee) if (i) Parent shall not have purchased any Shares pursuant to

  right to terminate this Agreement under this Section 8.01(b) shall not be
  available to any party whose failure to fulfill any obligation under this
  Agreement has been the cause of, or resulted in, the failure of the Tender
  Offer to be consummated on or before such date or (ii) any court of
  competent jurisdiction or other Governmental Entity shall have issued an
  order, decree, ruling or taken any other action restraining, enjoining or
  otherwise prohibiting the Merger and such order, decree, ruling or other
  action shall have become final and nonappealable; or

     (c) by Parent and Sub if prior to the purchase of Shares pursuant to the
  Tender Offer, the Special Committee or the Board of Directors of the
  Company shall have (including by amendment to the Schedule 14D-9) withdrawn
  or modified in a manner adverse to the Parent its approval or
  recommendation of the Tender Offer, the Merger or this Agreement or shall
  have resolved to do any of the foregoing; or

     (d) by the Company (acting through the Special Committee) if (i) due to
  an occurrence or circumstance, not involving a breach by the Company of its
  obligations hereunder, which would result in a failure to satisfy any of
  the conditions set forth in Annex A, hereto or otherwise, Parent shall have
  failed to commence the Tender Offer within nine business days following the
  date of this Agreement, terminated the Tender Offer or permitted the Tender
  Offer to expire without the purchase of Shares thereunder; or (ii) prior to
  the purchase of any Shares pursuant to the Tender Offer, either (1) Parent
  materially breaches or fails in any material respect to perform or comply
  with any of its material covenants and agreements contained herein, or (2)
  Parent breaches in any material respect any of its representations and
  warranties granted herein, and, in either case, a Parent Material Adverse
  Effect results therefrom; or

     (e) by the Company (acting through the Special Committee) if, in
  exercising its business judgment after consultation with its independent
  legal and financial advisors and taking into account their advice, it
  determines that a competing offer is superior to the offer embodied herein;
  provided, however, that in such event the Company will pay to Parent the
  sum of $1.25 million within two business days after acceptance of the
  competing offer, which sum will constitute reimbursement to Parent for all
  of its expenses incurred in connection with this Agreement; provided first,
  however, that the Company shall have materially complied with its
  obligations under Section 6.08.

Company with respect to the Tender Offer, the Merger and the transactions
contemplated hereby and supersedes all prior agreements and undertakings, both
written and oral, among the parities, or any of them, with respect to these
matters other than the Confidentiality Agreement, which shall remain in full
force and effect until the Effective Time; and (b) shall not be assigned,
except that the Parent may assign any of its rights and obligations hereunder,
including, without limitation, the right to purchase any or all of the Shares
tendered pursuant to the Tender Offer, to Parent or one or more direct or
indirectly wholly owned subsidiaries of Parent; provided, however, that no such
assignment shall relieve the Parent of its obligations hereunder.

   Section 9.07 SEVERABILITY. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any terms or
provisions of this Agreement in any other jurisdiction. If any provision of
this Agreement is so broad as to be unenforceable, the provision shall be
interpreted to be only so broad as is enforceable.

   Section 9.08 PARTIES IN INTEREST. This Agreement shall be binding upon and
inure solely to the benefit of each party hereto and their respective
successors, legal representatives and permitted assigns, and, except for the

intended to or shall confer upon any other person any rights, benefits or
remedies of any nature whatsoever under or by reason of this Agreement.

   Section 9.09 COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed to be an original, but all of which
shall constitute one and the same agreement.

   Section 9.10 AMENDMENT. This Agreement may not be amended except pursuant to
an instrument in writing signed by the Company following approval of such
action by the Special Committee and signed by Parent and Sub; provided,
however, that after any approval of this Agreement by the stockholders of the
Company, no amendment may be made without the further approval of the
stockholders of the Company which would: (i) decrease the Merger Consideration;
(ii) change any other terms and conditions and this Agreement if any of the
changes would, individually or in the aggregate, materially adversely affect
the stockholders of the Company; or (iii) otherwise require stockholder
approval under the DGCL.

   Section 9.11 EXTENSION; WAIVER. At any time prior to the Effective Time,
whether before or after approval of this Agreement by the stockholders of the
Company, any party hereto, by action taken by the Special Committee on behalf
of the Company or by Parent and Sub, as the case may be, may (a) extend the
time for the performance of any of the obligations or other acts of any other
party hereto, (b) waive any inaccuracies in the representations and warranties
contained herein or in any document, certificate or writing delivered pursuant
hereto, or (c) waive compliance with any of the agreements or any other party
or with any

                                      A-19

conditions to its own obligations. Any agreement on the part of a party hereto
to any such extension or waiver shall be valid only if set forth in an
instrument in writing signed on behalf of such party by a duly authorized
officer.

   Section 9.12 HEADINGS. The descriptive headings used herein are inserted for
convenience of reference only and are not intended to be part of or to affect

occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached.
It is accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions of this Agreement in any court of the State of
Delaware or of the United States located in the State of Delaware in the event
any dispute arises out of this Agreement or any of the transactions
contemplated by this Agreement, and each party will not attempt to deny or
defeat personal jurisdiction or venue in any such court by motion or other
request for leave from any such court.

guarantees: (i) the performance by Sub of all of Sub's obligations under this
Agreement; and (ii) the post-closing performance by the Surviving Corporation
(or any successor thereto) of all of the Surviving Corporation's post-closing

                                    ANNEX A

                         CONDITIONS TO THE TENDER OFFER

   Notwithstanding any other provision of the Tender Offer, and in addition to
(and not in limitation of) the Parent's rights to extend and amend the Tender
Offer at any time in its sole discretion in accordance with (and subject to)
the terms of this Agreement, Parent shall not be required to accept for
payment, purchase or pay for, subject to any applicable rules and regulations
of the SEC, including Rule 14e-1(c) under the Exchange Act, and may delay the
acceptance for payment of or, subject to the restriction referred to above, the
payment for, any tendered Shares (whether or not any Shares theretofore have
been accepted for payment or paid for pursuant to the Tender Offer), and may
terminate the Tender Offer as to any Shares not then paid for, if at any time
on or after October 24, 2000 and prior to the time of payment for any such
Shares, any of the following events shall occur:

     (a) there shall have been any action taken, or any statute, rule,
  regulation, judgment, order or injunction promulgated, entered, enforced,
  enacted, issued or deemed applicable to the Tender Offer in the Merger, or
  the Parent, the Company or any other affiliate of Parent, by any
  Governmental Entity or any court of competent jurisdiction (i) that makes
  illegal or otherwise directly or indirectly restrains or prohibits or makes
  materially more costly the making of the Tender Offer, the acceptance for
  payment of, or payment for, any Shares by Parent, Sub or any other
  affiliate of Parent pursuant to the Tender Offer, or the consummation of
  the Merger; (ii) that prohibits or materially limits the ownership or
  operation by the Company, Parent or any of their subsidiaries of all or any
  material portion of the business or assets of the Company, the Parent or
  any of their subsidiaries; (iii) that imposes limitations on the ability of
  Parent, Sub or any other affiliate of Parent to exercise full rights of
  ownership of any Shares, including, without limitation, the right to vote
  any Shares acquired by Parent pursuant to the Tender Offer or otherwise on
  all matters properly presented to the Company's stockholders, including,
  without limitation, the approval and adoption of this Agreement and the
  transactions contemplated by this Agreement; (iv) that compels the Company,
  Parent or any of Parent's subsidiaries to dispose of or hold separate all
  or a material portion of the business or assets of the Company; or (v) that
  is reasonably likely to result, directly or indirectly, in any of the
  consequences referred to in clauses (i) through (iv) of this paragraph (a);

     (b) any of the representations or warranties of the Company set forth in
  this Agreement that are qualified by materiality or Company Material
  Adverse Effect shall not be true and correct, or any of the representations
  and warranties of the Company set forth in this Agreement that are not so
  qualified shall not be true and correct in all material respects, in each
  case, as if such representations or warranties were made as of such time on
  or after the date of this Agreement (except to the extent such
  representations and warranties speak as of a specific date or period, or as
  of the date of this Agreement, in which case such representations and
  warranties shall not be so true and correct or true and correct in all
  material respects, as the case may be, as of such specific date or as of
  the date of this Agreement, respectively);

     (c) the Company shall have failed to perform in any material respect any
  obligation or to comply in any material respect with any agreement or
  covenant of the Company to be performed or complied with by it under this
  Agreement;

     (d) the Board of Directors of the Company, based on the recommendation
  of the Special Committee, shall have (including by amendment to the
  Schedule 14D-9) withdrawn or modified in a manner adverse to Parent or Sub
  its approval or recommendation of the Tender Offer, the Merger or this
  Agreement or shall have resolved to do any of the foregoing;

     (e) the Company (acting through the Special Committee), Parent and Sub
  shall have agreed that Parent shall terminate the Tender Offer or postpone
  the acceptance for payment of or payment for shares thereunder;

     (f) (i) any general suspension of trading in securities on any national
  securities exchange or in the over-the-counter market, (ii) the declaration
  of a banking moratorium or any suspension of payments in

                                      A-22
<PAGE>

  respect of banks by a United States Governmental Entity, or (iii) any
  mandatory limitation by a Governmental Entity that materially and adversely
  effects the extension of credit by banks or other financial institutions;
  or

     (g) this Agreement shall have been terminated in accordance with its
  terms;

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

   The foregoing conditions are for the sole benefit of Parent, Sub and their
respective affiliates and may be asserted by Parent or Sub, in whole or in
part, at any time and from time to time in the sole discretion of Parent or
Sub. The failure by Parent or Sub at any time to exercise its rights under any
of the foregoing conditions shall not be deemed a waiver of any such rights and
each such right shall be deemed an ongoing right which may be asserted at any
time or from time to time.

   Should the Offer be terminated pursuant to any of the foregoing provisions,
all tendered Shares not theretofore accepted for payment shall forthwith be
returned to the tendering stockholders.

The Board of Directors of pcOrder.com, Inc.
5001 Plaza on the Lake
Austin, Texas 78746

Members of the Special Committee and the Board:

   You have requested our opinion as to the fairness, from a financial point of
view, to the holders of Class A Common Stock of pcOrder.com, Inc., a Delaware
corporation (the "Company"), other than Trilogy Software, Inc. ("Parent"), POI
Acquisition Corp. ("Sub") and any affiliate of Parent other than the Company
(the "Unaffiliated Stockholders"), of the cash consideration to be received by
holders of Class A Common Stock of the Company in the transaction described
below, pursuant to an Agreement and Plan of Merger (the "Agreement") among the
Company, Parent and Sub. The Agreement provides for the commencement by Parent
of a tender offer (the "Tender Offer") to purchase shares of Company Class A
Common Stock outstanding at a price of $6.375 per share, net to seller in cash
(the "Offer Price") and the subsequent merger (the "Merger") of Sub into the
Company in which the remaining shares of Class A Common Stock of the Company
will be converted and exchanged for cash equal to the Offer Price. The Tender
Offer and the Merger are collectively referred to as the "Transaction." The
terms and conditions of the Transaction are more fully set forth in the
Agreement.

   Dain Rauscher Wessels, a division of Dain Rauscher Incorporated ("Dain
Rauscher Wessels"), as part of its investment banking services, is regularly
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, corporate restructurings, underwritings, secondary
distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes.

   We are acting as financial advisor to the Company in connection with the
Transaction and will receive a fee for our services, a portion of which is
contingent upon the consummation of the Transaction. We will also receive a fee
for providing this opinion. This opinion fee is not contingent upon the
consummation of the Transaction. In addition, the Company has agreed to
indemnify us for certain liabilities arising out of our engagement. In the
ordinary course of business, we and our affiliates may trade securities of the
Company for our own account and for the accounts of our customers and,
accordingly, may at any time hold a long or short position in such securities.

   In connection with our review of the Transaction, and in arriving at our
opinion, we have: (i) reviewed and analyzed the financial terms of the draft
dated October 24, 2000 of the Agreement; (ii) reviewed and analyzed certain
publicly available financial and other data with respect to the Company and
certain other historical relevant operating data relating to the Company made
available to us from published sources and from the internal records of the
Company; (iii) conducted discussions with members of the senior management of
the Company with respect to the business prospects and financial outlook of the
Company; (iv) reviewed the reported prices and trading activity for Company
common stock; (v) compared the financial performance of the Company and the
prices of the Company common stock with that of certain other comparable
publicly-traded companies and their securities; (vi) reviewed the financial
terms, to the extent publicly available, of certain comparable transactions;
(vii) compared the transaction premium paid to the holders of Class A Common
Stock to the transaction premiums paid in selected transactions where the buyer
has a controlling interest in a publicly traded company prior to the
acquisition; and (viii) compared the transaction premium paid to the holders of
the Class A Common Stock to the transaction premiums paid in selected
transaction of other software companies. In addition, except as noted below, we
have conducted such other analyses and examinations and considered such other
financial, economic and market criteria as we have deemed necessary in arriving
at our opinion. The Company did not provide us with forecast financial
information beyond fiscal 2001, nor did the Company think that there was a
reasonable basis for providing forecast information beyond fiscal 2001. As a
result of the limited forecast financial information, we were unable to employ
a discounted cash flow analysis.

   In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of the financial, legal, tax, operating and other information
provided to us by the Company (including, without limitation, the financial
statements and related notes thereto of the Company), and have not assumed
responsibility for independently verifying and have not independently verified
such information. With respect to the data and discussions relating to the
business prospects and financial outlook of the Company, upon advice of the
Company, we have assumed that such data has been reasonably prepared on a basis
reflecting the best currently available estimates and judgments of the
management of the Company as to the future financial performance of the Company
and that the Company will perform substantially in accordance with such
financial data and estimates. We express no opinion as to such financial data
and estimates or the assumptions on which they were based.

   In arriving at our opinion, we have not performed nor been furnished any
appraisals or valuations of any specific assets or liabilities of the Company
and have not been furnished with any such appraisals or valuations. In
addition, we have not assumed any obligation to conduct, and have not
conducted, any physical inspection of the property or facilities of the
Company. Additionally, we have not been asked and did not consider the possible
effects of any litigation or other legal claims. Our opinion relates to the
Company as a going concern and, accordingly, we express no opinion regarding
its liquidation value.

   Our opinion speaks only as of the date hereof, is based on the conditions as
they exist and information which we have been supplied as of the date hereof,
and is without regard to any market, economic, financial, legal or other
circumstances or event of any kind or nature which may exist or occur after
such date. We have not undertaken to reaffirm or revise this opinion or
otherwise comment upon any events occurring after the date hereof and do not
have any obligation to update, revise or reaffirm this opinion.

   Our advisory services and the opinion expressed herein are provided for the
information and assistance of the Special Committee and the Board in connection
with its consideration of the Transaction contemplated by the Agreement, and
does not constitute a recommendation to any stockholder of the Company
regarding whether to tender shares of common stock in the Tender Offer or how
to vote in the Merger. This opinion shall not be otherwise relied upon,
published or otherwise used, nor shall any public references to us be made,

without prior written consent. However, notwithstanding the foregoing, we
consent to inclusion of this opinion in the Schedule TO, Schedule 13E-3 and
Schedule 14D-9 relating to the Tender Offer and the proxy statement (if any)
relating to the Merger, in accordance with the terms of our engagement with the
Company.

   We express no views as to, and our opinion does not address, the merits of
the underlying decision by the Company to engage in the Transaction, the
relative merits of the Transaction as compared to any alternative business
strategies or the effect of any other transaction in which the Company might
engage, including, without limitation, a transaction which may result in a
change of control of the Company affecting the holders of any class of capital
stock of the Company.

   Our opinion addresses solely the fairness of the Offer Price to be paid to
the holders of Class A Common Stock (other than Parent, Sub and any affiliate
of Parent) in the Transaction and does not address any other term or agreement
relating to the Transaction, or the ability of Parent to finance or otherwise
successfully consummate the Transaction.

   We are not expressing any opinion herein as to the prices at which Company
common stock has traded or will trade following the announcement of the
Transaction.

   Based on our experience as investment bankers and subject to the foregoing,
including the various assumptions and limitations set forth herein, it is our
opinion that, as of the date hereof, the Offer Price proposed to be paid in the
Transaction pursuant to the Agreement for the Class A Common Stock of the
Company is fair, from a financial point of view, to the Unaffiliated
Stockholders as of the date hereof.

                                          Very truly yours,

                                          DAIN RAUSCHER WESSELS,
                                          a division of Dain Rauscher

           EXCERPTS FROM THE GENERAL CORPORATION LAW OF THE STATE OF
           DELAWARE RELATING TO THE RIGHTS OF DISSENTING STOCKHOLDERS

                              262 APPRAISAL RIGHTS

   (a) Any stockholder of a corporation of this State who holds shares of stock
on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to Section
228 of this title shall be entitled to an appraisal by the Court of Chancery of
the fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and
the words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions
thereof, solely of stock of a corporation, which stock is deposited with the
depository.

   (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to Section 251 (other than a merger effected pursuant to
Section 251(g)), Section 252, Section 254, Section 257, Section 258, Section
263 or Section 264 of this title:

     (1) Provided, however, that no appraisal rights under this section shall
  be available for the shares of any class or series of stock, which stock,
  or depository receipts in respect thereof, at the record date fixed to
  determine the stockholders entitled to receive notice of and to vote at the
  meeting of stockholders to act upon the agreement of merger or
  consolidation, were either (i) listed on a national securities exchange or
  designated as a national market system security on an inter-dealer
  quotation system by the National Association of Securities Dealers, Inc. or
  (ii) held of record by more than 2,000 holders; and further provided that
  no appraisal rights shall be available for any shares of stock of the
  constituent corporation surviving a merger if the merger did not require
  for its approval the vote of the stockholders of the surviving corporation
  as provided in subsection (f) of Section 251 of this title.

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

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

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

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

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

                                      C-1

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

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

   (d) Appraisal rights shall be perfected as follows:

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

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

                                      C-2
<PAGE>

  facts stated therein. For purposes of determining the stockholder entitled
  to receive either notice, each constituent corporation may fix, in advance,
  a record date that shall be not more than 10 days prior to the date the
  notice is given; provided that, if the notice is given on or after the
  effective date of the merger or consolidation, the record date shall be
  such effective date. If no record date is fixed and the notice is given
  prior to the effective date, the record date shall be the close of business
  on the day next preceding the day on which the notice is given.

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

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

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

   (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger
or consolidation, together with a fair rate of interest, if any, to be paid
upon the amount determined to be the fair value. In determining such fair
value, the Court shall take into account all relevant factors. In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest which the surviving or resulting corporation
would have had to pay to borrow money during the pendency of the proceeding.
Upon application by the surviving or resulting corporation or by any
stockholder entitled to participate in the appraisal proceeding, the Court may,
in its discretion, permit discovery or other pretrial proceedings and may
proceed to trial upon the appraisal prior to the final determination of the
stockholder entitled to an appraisal. Any stockholder whose name appears on the
list filed by the surviving or

                                      C-3
<PAGE>

resulting corporation pursuant to subsection (f) of this section and who has
submitted his certificates of stock to the Register in Chancery, if such is
required, may participate fully in all proceedings until it is finally
determined that he is not entitled to appraisal rights under this section.

   (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to
the stockholders entitled thereto. Interest may be simple or compound, as the
Court may direct. Payment shall be so made to each such stockholder, in the
case of holders of uncertificated stock forthwith, and the case of holders of
shares represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

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

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

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