                    AMENDED AND RESTATED ASSIGNMENT AGREEMENT

      This Amended and Restated Assignment Agreement is made as of November 3,
2000 (the "Effective Date") by PURCHASEPRO.COM, INC., a Nevada corporation whose
address is 3291 N. Buffalo Drive, Las Vegas, Nevada 89129 ("PurchasePro"), and
E-MARKETPRO, LLC, a Kentucky limited liability company whose address is 2623
Regency Road, Lexington, Kentucky, 40503 ("E-MarketPro"). This Amended and
Restated Assignment Agreement amends and restates in its entirety that certain
Assignment Agreement between the parties dated as of August 17, 2000.

      WITNESSETH:

      WHEREAS, PurchasePro (under its prior name Purchase Pro International,
Inc.) and E-MarketPro are parties to an Agreement dated the 1st day of February
1999 (as amended, the "Marketing Agreement"), pursuant to which E-MarketPro was
granted certain exclusive and non-exclusive rights to market and promote
subscriptions to access and use PurchasePro's business-to-business bidding and
procurement environment (the "PurchasePro Solution") on the terms set forth
therein;

      WHEREAS, PurchasePro and E-MarketPro desire to terminate the Marketing
Agreement; and

      WHEREAS, E-MarketPro desires to assign to PurchasePro, and PurchasePro
desires to accept, certain contract rights of E-MarketPro and the rights to
E-MarketPro's name and other registered and unregistered trademarks, trade-names
and other intellectual property and all goodwill associated therewith
(collectively, the "E-MarketPro Trademarks");

      NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is acknowledged, the parties agree as follows:

ARTICLE 1.

1.1 The parties mutually agree to, and do hereby, novate and terminate the
Marketing Agreement as of the Effective Date in all respects; thus, as of the
Effective Date, the Marketing Agreement is of no force or effect. Each party
acknowledges and agrees that the other party has fully performed its obligations
and responsibilities under the Marketing Agreement and any non-performance or
partial performance of the Marketing Agreement by the other party is hereby
waived. Without limiting the generality of the foregoing, the parties
acknowledge and agree that:

      A. All rights granted under the Marketing Agreement to market and promote
subscriptions to access and use the PurchasePro Solution shall revert back to
PurchasePro as of the Effective Date.

      B. Pursuant to E-MarketPro's marketing efforts under the Marketing
Agreement, the parties hereto executed a Software Agency and Services Agreement
dated May 3, 1999 with ZoomTown.com, Inc. (the "Zoomtown Agreement"). Although
the Zoomtown Agreement amended the Marketing Agreement in certain respects,
termination of the Marketing Agreement shall not affect or amend the Zoomtown
Agreement, per se (see Section 1.2).

      C. The Marketing Agreement provides for certain amounts to be paid to
E-MarketPro. The parties agree to offset these amounts against the total
indebtedness of E-MarketPro for purposes of clause (i) of Section 1.4.

      D. Under the Marketing Agreement, E-MarketPro was granted the right to
receive certain options to purchase common stock of PurchasePro as certain
conditions were met. All such options are cancelled and all rights of
E-MarketPro to earn or receive options under the Marketing Agreement are
terminated.

      E. E-MarketPro shall not have, and hereby waives, any right or claim under
the Marketing Agreement or otherwise to compensation for its efforts to market
and promote the PurchasePro Solution or for or with respect to any PurchasePro
customers or subscriptions to access and use the PurchasePro Solution that,
directly or indirectly, were, or in the future are, obtained by reason of or
arising from those efforts in whole or part.

1.2 E-MarketPro hereby assigns and delegates to PurchasePro, and PurchasePro
hereby accepts, all of E-MarketPro's interests, rights and obligations (i) under
the Zoomtown Agreement and (ii) in and to the E-MarketPro Trademarks. In this
regard:

      A. Said assignment is subject to the prior consent of Zoomtown, Inc., as
provided in Section 12 of the Zoomtown Agreement (captioned "Assignment") and
any other party to any E-MarketPro Agreement, the assignment of which hereunder
is subject to such party's prior written consent. The parties will cooperate to
obtain such consent as soon as practicable.

<PAGE>

      B. Said assignment includes all rights of E-MarketPro to receive payment
under the Zoomtown Agreement, including payments, if any, accrued but not yet
paid or otherwise owing with respect to periods prior to the Effective Date.
PurchasePro agrees, however, that E-MarketPro may retain any payments already
received under the Zoomtown Agreement.

      C. Said assignment notwithstanding, E-MarketPro shall continue to be bound
by and agrees to comply fully with its obligations under Section 15 of the
Zoomtown Agreement (captioned "Confidentiality and Non-Disclosure"), and with
any other term or provision imposing an obligation on E-MarketPro to hold
information confidential as set forth in any E-MarketPro Agreement.

      D. Said assignment may be witnessed by one or more additional instruments
or documents to effectively convey the E-MarketPro Trademarks, all of which
E-MarketPro hereby agrees to fully execute and deliver as requested by
PurchasePro.

1.3 As the consideration for the termination of the Marketing Agreement and the
assignment of the E-MarketPro Trademarks, PurchasePro shall issue to E-MarketPro
(i) on the date of satisfaction of all conditions set forth herein ("Closing
Date"), 100,000 shares of the common stock of PurchasePro, subject to adjustment
as set forth in Section 1.5, and (ii) on the first anniversary of the date
hereof, such shares as determined pursuant to Section 1.4 (the "Subject
Shares"). The issuance of those Subject Shares to be issued pursuant to clause
(i) above shall occur promptly after the consent to the assignment referenced in
Section 1.2A is obtained.

1.4 On the first anniversary of the Closing Date, as additional consideration
hereunder, PurchasePro shall issue to E-MarketPro that number of shares of the
common stock of PurchasePro determined as follows: (i) 100,000 shares of the
common stock of PurchasePro times a fraction the numerator of which is the
aggregate amount of all payments for which Referred Customers (defined below)
are obligated to make to PurchasePro pursuant to bona fide contracts entered
into with PurchasePro as of such date and the denominator of which is
$1,440,000, provided the result thereof shall not exceed 100,000 shares, less
(ii) such number of shares having a value as of the date hereof equal to the
total amount of all indebtedness of E-MarketPro to PurchasePro as of the date
hereof less any amounts owing from PurchasePro to E-MarketPro as of the date
hereof. For purposes hereof, a "Referred Customer" shall refer to any existing
customer purchasing a new product or service hereafter and any new customer with
respect to either of which E-MarketPro would have received consideration under
the Marketing Agreement absent termination thereof pursuant to this Agreement.

1.5 The obligation of PurchasePro to issue shares to E-MarketPro pursuant to
this Agreement shall be subject to (i) receipt of approval from PurchasePro's
Board of Directors or any committee thereof upon which authority to approve such
issuance has been duly conferred by the Board of Directors, (ii) receipt of
Zoomtown's consent pursuant to Section 1.2(A) above, and (iii) the execution of
a non-competition agreement in a form acceptable to PurchasePro by Brad Redmon
and Rick Redmon. The number of shares to be issued to E-MarketPro pursuant to
clause (i) of Section 1.3 shall be adjusted, if equitable, as mutually agreed by
the parties hereto in the event Zoomtown does not consent to the assignment of
the Zoomtown Agreement as contemplated herein. In the event that the Board or
Directors or any applicable committee thereof does not approve the issuance of
shares hereunder, neither party shall be obligated hereunder and the Marketing
Agreement shall not be terminated and shall remain in full force and effect.

1.6 If PurchasePro's issued and outstanding common shares are increased or
decreased or are changed into or exchanged for a different number or kind of
shares or securities as the result of any one or more reorganizations,
recapitalizations, stock splits, reverse stock splits, stock dividends or the
like, an appropriate adjustment shall be made in the number and/or type of
shares or securities subject to issuance under Section 1.4. In

<PAGE>

the event prior to the issuance of shares under Section 1.4 of (i) any
consolidation, merger or reorganization of PurchasePro with another entity in
which PurchasePro is not the surviving entity, (ii) any liquidation or
dissolution of PurchasePro, or (iii) any distribution to shareholders in
connection with a sale of all or a major part of PurchasePro's assets, then
PurchasePro shall notify E-MarketPro in writing of such transaction or
distribution at least ten (10) business days prior to consummation thereof and
make appropriate provision in connection with such transaction or distribution
for PurchasePro's obligations under Section 1.4 of this Agreement.

ARTICLE 2.

2.1 PurchasePro represents and warrants to E-MarketPro that:

      A. PurchasePro is a corporation duly organized, in good standing and
validly existing under the laws of the State of Nevada. The execution, delivery
and performance of this Agreement by PurchasePro has been duly authorized.

      B. The Subject Shares will be validly issued, fully paid and
non-assessable but shall be subject to all applicable restrictions on transfer
under state or federal securities laws.

2.2 E-MarketPro represents and warrants to PurchasePro that:

      A. E-MarketPro is a limited liability company duly organized, in good
standing and validly existing under the laws of the State of Kentucky. The
execution, delivery and performance of this Agreement by E-MarketPro has been
duly authorized.

      B. E-MarketPro is aware of PurchasePro's business affairs and financial
condition, has had sufficient opportunity to ask questions of and receive
answers from representatives of PurchasePro and has acquired sufficient
information about PurchasePro to reach an informed and knowledgeable decision to
acquire the Subject Shares pursuant to this Agreement. E-MarketPro is acquiring
the Subject Shares for investment for E-MarketPro's own account only and not
with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act"). E-MarketPro is an "accredited investor" as such term is defined in Rule
501(a) of Regulation D under the Securities Act and has such knowledge and
experience in financial and business matters as to be capable of evaluating the
merits and risks of investing in the Subject Shares, including a complete loss
of its investment. E-MarketPro understands that the issuance of the Subject
Shares pursuant to this Agreement has not been registered under the Securities
Act in reliance on a specific exemption from registration which depends upon,
among other things, the bona fide nature of E-MarketPro's investment intent as
expressed herein.

2.3 E-MarketPro acknowledges and understands that the Subject Shares must be
held indefinitely unless they are subsequently registered under the Securities
Act or an exemption from such registration is available. E-MarketPro understands
that the Subject Shares will be imprinted with a legend that prohibits the
transfer of such securities, unless they are registered or such registration is
not required in the opinion of legal counsel for PurchasePro. E-MarketPro
understands that the Subject Shares are "restricted securities" under the
federal securities laws inasmuch as they are being acquired from PurchasePro in
a transaction not involving a public offering and that, under such laws and
applicable regulations, such securities may be resold without registration under
the Securities Act only in certain limited circumstances. In this connection,
E-MarketPro represents that it is familiar with SEC Rule 144, as presently in
effect, and understands the resale limitations imposed thereby and by the
Securities Act. E-MarketPro further understands that, at the time E-MarketPro
wishes to sell any Subject Shares, there may be no public market upon which to
make such a sale and that, even if such a public market then exists, PurchasePro
may not be satisfying the current public information requirements of Rule 144
and, in such event, E-MarketPro would be precluded from selling such securities
under Rule 144 even if any minimum holding period has been satisfied.

ARTICLE 3.

3.1 E-MarketPro acknowledges that, during its performance under the Marketing
Agreement, it obtained certain confidential information belonging to or
concerning PurchasePro and its business, including without limitation lists of
actual and potential customers, pricing information, business and product plans
and marketing strategies. E-MarketPro agrees not to disclose to any third party
or use for any purpose any such information without the express written consent
of PurchasePro, except for any information which ceases to be confidential
without any fault on the part of E-MarketPro.

<PAGE>

3.2 All notices under with this Agreement shall be in writing and shall be
effective upon receipt. All notices shall be addressed to the recipient at its
address shown above (or, if different, the latest address for notices that such
party provides by written notice to the other party).

3.3 This Agreement shall be governed by the laws of the State of Nevada,
excluding its choice of laws provisions. This Agreement is the entire agreement
between the parties relating to the subject matter hereof and supersedes all
prior or simultaneous written or oral representations, discussions,
negotiations, understandings and agreements relating to such subject matter. No
provision of this Agreement may be waived unless in a writing signed by both
parties, and any such waiver will not operate or be construed as a waiver of any
other provision or any subsequent breach by the other party. This Agreement
shall be binding and inure to the benefit of the parties, their successors,
representatives, and assigns. This Agreement may be executed in multiple
counterparts, each shall be an original but all of which constitute one and the
same instrument. This Agreement will not be binding upon either party until it
has been signed by both parties.

      IN WITNESS WHEREOF, the parties have executed this Agreement, with the
intent to be bound as of the Effective Date.

the Software and Documentation made by or on behalf of PurchasePro as permitted
by this Agreement.

      2.2  Special Limitations Applicable to Source Code Components of the
Software.

            (a) Notwithstanding Section 2.1 above, PurchasePro shall not: (i)
      use the Software, Integrated Software or any derivative works thereof for
      purposes which do not include processing auction transactions; or (ii)
      develop with the Software and Integrated Software any applications which
      include less than a substantial amount of the auction services
      functionality contained in the Software and Integrated Software.

            (b) PurchasePro acknowledges that the source code components of the
      Software constitute AuctioNet Confidential Information. PurchasePro shall
      treat such source code components as AuctioNet Confidential Information
      pursuant to Section 10 below and otherwise with at least the same degree
      of care as it treats the source code to its own proprietary software, and
      further agrees that access to such components shall be strictly limited to
      employees of PurchasePro who have a need to access such components and who
      have been advised of the confidential and proprietary nature of such
      components, and consultants or contractors of PurchasePro who have a need
      to access such components, have been advised of the confidential and
      proprietary nature of such components, and have entered into a
      non-disclosure agreement of a form as protective of such components as are
      the confidentiality protections set forth in this Agreement which provides
      that AuctioNet is an intended third party beneficiary of such agreement.
      PurchasePro shall maintain records listing all such contractors and shall
      provide AuctioNet with access thereto on the reasonable request of
      AuctioNet. Notwithstanding

                                      -3-
<PAGE>

      the foregoing, PurchasePro shall be permitted to disclose the source
      components to AOL in performing its obligations pursuant to that certain
      Technology Development Agreement by and between PurchasePro and AOL dated
      March 15, 2000.

            (c) PurchasePro shall, prior to implementing any updates,
      additions, modifications or changes ("Modifications") to the Software,
      provide AuctioNet with notice of its intent to do so in the form of a
      reasonably acceptable statement of work (inclusive of project timelines)
      for the performance of such Modification. AuctioNet shall have the right
      to itself implement such Modification at its expense; provided that
      AuctioNet must, within three (3) business days of receiving any such
      statement of work from PurchasePro, provide PurchasePro with a
      determination of whether AuctioNet desires to implement such
      Modifications. Modifications implemented by AuctioNet shall be delivered
      to PurchasePro as either an Update or Upgrade (whichever is more
      applicable). In the event AuctioNet determines not to implement any such
      Modification or loses the right to do so under the foregoing proviso,
      PurchasePro may, at its option, itself implement such Modification. In the
      event AuctioNet performs the implementation, such Modification shall be
      subject to acceptance by PurchasePro and AuctioNet will work with
      PurchasePro to resolve to PurchasePro's reasonable satisfaction any issues
      or concerns PurchasePro has with such Modification; and such Modification
      shall for all purposes be deemed to be, and otherwise treated in the same
      manner as, either an Update or Upgrade (whichever is more applicable).

            (d) AuctioNet shall have no obligations under this Agreement
      (including, without limitation, as regards maintenance and support) for
      Modifications to the Software developed and implemented by PurchasePro
      ("PurchasePro Modifications"). PurchasePro Modifications (to the extent
      exclusive of the Software) are owned by and shall remain the sole property
      of PurchasePro.

      2.3  Ownership. AuctioNet or its third party licensors hereby retain all
right, title, and interest in and to the Software and the Documentation,
including all copyrights, patents, trade secret rights, trademarks and other
intellectual property rights therein. All rights in and to the foregoing not
expressly granted hereunder are reserved to AuctioNet or its licensors. The
Software and Documentation and all copies thereof are licensed, not sold, to
PurchasePro. Notwithstanding anything to the contrary contained herein, all
changes, modifications and enhancements or derivative works made to the
Softwareor Documentation by PurchasePro hereunder as permitted in this Section 2
shall be owned by PurchasePro, including all copyrights, patents, trade secret
rights or other intellectual property rights therein.

3.     Delivery of Software.

AuctioNet shall issue to PurchasePro, via CD-ROM, tape or such other media as
reasonably requested by PurchasePro, as soon as practicable after the Effective
Date, four (4) machine-readable copies of the Software (two (2) copies of the
Software in source code format and two (2) copies in object code form). Upon
creation of any Documentation by AuctioNet, AuctioNet shall promptly deliver
such documentation to PurchasePro.

4.     Fees; Taxes; Revenue Allocation.

      4.1  Fees. In consideration for (a) the licenses granted to PurchasePro
under Section 2 of this Agreement; (b) Maintenance and Support Services; (c)
Updates and Upgrades; (d) Integration Services (as defined in Section 5.2
below); and (e) all other services as described in Section 5.4, PurchasePro
shall pay AuctioNet the fees as specified in Exhibit C hereto (the "Fees").
Payment terms of such Fees shall

                                      -4-
<PAGE>

be as set forth in Exhibit C hereto. Maintenance and Support Services shall
terminate upon termination or expiration of this Agreement, unless the Parties
agree otherwise.

      4.2  Revenue Allocation.

      (a) Within thirty (30) days after the end of each calendar quarter
during the term of this Agreement, AuctioNet shall pay PurchasePro a
transaction fee equal to fifty percent (50%) of all net revenue generated by
AuctioNet from AuctioNet Services during such calendar quarter. For the
purposes of this Section 4.2(a), "net revenue" shall mean all revenue or its
equivalent obtained through the exploitation of the AuctioNet Services, less

therewith for such goods, less credit card processing and validation fees,

This example assumes a 20% partnership revenue share but exact percentage will
vary depending upon partnership agreements.

      (b) Within thirty (30) days after the end of each calendar quarter during
the term of this Agreement, PurchasePro shall pay AuctioNet fifty percent (50%)
of all transaction fees PurchasePro generates from transactions by PurchasePro
Customers using the Software or Integrated Software but not the AuctioNet
Services during such calendar quarter. For the purposes of this Section 4.2(b),

      (c) Within thirty (30) days after collection by PurchasePro from any
PurchasePro customer, PurchasePro shall, for any PurchasePro Software containing
Integrated Software which PurchasePro Software was licensed during such quarter
to such PurchasePro customer for installation and use by such customer on
computer equipment owned and/or controlled by such customer, pay over to
AuctioNet out of the license fee received by PurchasePro for such customer for
such Software, the greater of (a) twenty-five percent (25%) of the Integrated
Software Fee applicable to such Software and (b) $15,000.00.

      4.3  Taxes. All fees due hereunder to either Party (the "Collecting
Party") are exclusive of all applicable taxes and duties assessed in connection
with this Agreement and the other Party's (the "Paying Party") performance
hereunder by any authority, which shall be paid by the Paying Party or, if paid
by the Collecting Party, promptly reimbursed. This provision does not apply to
any taxes for which the Paying Party is exempt, provided the Paying Party has
furnished the Collecting Party with a valid tax exemption certificate, or to the
Collecting Party's income or franchise taxes.

      4.4  Audit Right. During the term of this Agreement and for a period of
one (1) year following the expiration or termination of this Agreement for any
reason, each Party will maintain complete and accurate books of accounts,
records and such other material necessary to calculate amounts due to the other
Party under this Agreement. Each Party will permit the other Party, through a
nationally recognized certified public accounting firm ("CPA") designated by
such other Party (subject to execution of a reasonable non-disclosure agreement
by said CPA), upon reasonable notice and during normal business hours, to
inspect these books, records and other materials once per year during the term
of this Agreement plus once up to twelve (12) months following the expiration or
termination of this Agreement. Each Party will provide full and complete
assistance in such audit effort as the other Party may reasonably require. In
the event the audit reveals an underpayment in the payment obligations of the
Party being audited by more than five percent (5%), the Party being audited will
promptly pay the auditing Party such underpayment amount plus interest
calculated at the lesser of one and one-half percent (1 1/2%) per month or the
highest rate permitted by law on the underpaid amount.

5.     Maintenance and Support; Integration Services; Service Levels.

technical support questions or problems related solely to the use of the
Software (as a stand-alone product or as part of the Integrated Software),
PurchasePro may escalate the question or problem directly to AuctioNet for
AuctioNet to resolve as described in the schedule set forth in Exhibit B hereto
("Level 2 Support"). Without limiting the generality of the foregoing, during
such two (2) year term, AuctioNet shall maintain the Software as part of the
Integrated Software so that all of the functionality, performance and
capabilities of the Software as made generally available to AuctioNet's
customers will be incorporated in the Software as part of the Integrated
Software.

      5.2   Service Levels. Until two (2) years after the Effective Date,
AuctioNet shall be responsible for ensuring that at all times the Software and
Integrated Software is maintained, and the AuctioNet Services shall be
performed, at levels at least equal in all material respects to the service
levels set forth on Exhibit D hereto, except during the occurrence of a force
majeure event described in Section 13.7. AuctioNet shall establish and maintain
arrangements for emergency back-up services acceptable to PurchasePro. AuctioNet
shall take all commercially reasonable measures to minimize the damage caused by
any impairment resulting from any actual interruption or shutdown of any
facility that either (a) prevents AuctioNet from performing its obligations
hereunder or (b) causes a substantive disruption of the

                                      -6-
<PAGE>

use by PurchasePro or any PurchasePro Customers of theAuctioNet Services,
Software or Integrated Software, in each case for a period of at least five (5)
business days, and, in cooperation with PurchasePro and any third parties, to
avoid recurrence of such interruption or shutdown. AuctioNet shall organize,
implement, monitor and apply all commercially reasonable disaster protection
mechanisms as required to minimize the damage caused by any such impairment. In
the event of any such impairment, AuctioNet shall work diligently and with all
commercially reasonable efforts to restore the ability of PurchasePro and all

            (a) AuctioNet shall integrate the Software into the PurchasePro
Software (i.e., develop the Integrated Software) for use by PurchasePro by
interface between the PurchasePro Software and the AuctioNet Software on an
application service provider basis and by integration into the PurchasePro
Software on an the original equipment manufacturer basis (the "Integration",
with the services, functions and responsibilities being performed by AuctioNet
to successfully complete the Integration being hereinafter referred to as the
"Integration Services"). AuctioNet shall dedicate that number of qualified
personnel and amount of resources necessary to perform and complete the
Integration Services.

            (b) As soon as reasonably practicable after execution of this
Agreement, AuctioNet shall commence in good faith: (i) a study to capture and
record the business requirements PurchasePro is seeking to meet using the
functionality and capabilities of the Software as set forth in a writing to be
delivered by PurchasePro (the "Business Requirements"); and (ii) an analysis to
establish the methods and processes necessary for completing the Integration so
as to meet PurchasePro's business requirements (the "Integration Analysis").
Based upon the Integration Analysis, AuctioNet shall, no later than February 14,
2001, complete and deliver to PurchasePro for review a full draft of a proposed
Integration Plan (defined below). Without limiting the generality of the
foregoing, the Integration Plan shall include such details as are necessary and
appropriate to show how the Integration, when completed per the Integration
Plan, will meet the Business Requirements. PurchasePro shall review the
Integration Plan and, within 15 days of its receipt thereof, request in writing
any revisions it desires thereto. AuctioNet shall, within 15 days of receiving
any such requests from PurchasePro, revise the Integration Plan in accordance
with all reasonable requests of PurchasePro and resubmit the Integration Plan to
PurchasePro for approval. Within 15 days of receiving the re-submitted
Integration Plan, PurchasePro shall either finally approve such Integration Plan
or return the Integration Plan to AuctioNet with instructions regarding
necessary further revision (in which case the re-submittal and review process
shall be carried out again).

            (c) The Integration will be accomplished pursuant to a plan
developed by AuctioNet and approved by PurchasePro (the "Integration Plan"). The
Integration Plan shall encompass all relevant terms, conditions and components
for the completion of the Integration. The Integration Plan shall include, among
other things, a complete set of specifications for the Integrated Software and
provision of the AuctioNet Services, deliverables, milestones, time-lines for
completion, acceptance criteria (for acceptance of the Integrated Software by
PurchasePro), performance objectives and the specific responsibilities of each
Party.

            (d) AuctioNet and PurchasePro shall each perform the tasks required
of it by the Integration Plan so that the Integration will be completed in
accordance with the schedule set forth therein. AuctioNet and PurchasePro shall
be responsible for overall management of the Integration and shall use all

identify and resolve any problems encountered in the timely completion of each
task. AuctioNet shall provide

                                      -7-
<PAGE>

PurchasePro with weekly progress reports which describe in reasonable detail the
current status of the Integration, indication of the progress of the work being
performed in comparison to the Integration Plan, identification of actual or
anticipated problems, the impact of such problems on AuctioNet's work effort,
and action being taken or alternative actions to be taken to remedy such
problems. In addition, AuctioNet shall track all tasks and sub-tasks on-line
using Microsoft Project and shall at all times provide PurchasePro with access
thereto so as to enable PurchasePro to always be able to determine AuctioNet's
progress against the Integration Plan. AuctioNet agrees to use commercially
reasonable efforts to effect a smooth transition without disruption to any of
PurchasePro's business operations, except as contemplated by the Integration
Plan.

            (e) Other than as set forth in Exhibit C, PurchasePro shall not be
obligated to make any additional payments to AuctioNet in connection with the
Integration (and including, without limitation, for the Software, the Integrated
Software and the Integration Services) or otherwise, and each Party shall bear
its own costs and expenses associated with the Integration.

            (f) Any additional software developed by AuctioNet hereunder,
exclusive of the Software or Integrated Software, will be included in the
definition of "Software" for all intents and purposes of this Agreement.

            (g) Upon the execution of this Agreement, AuctioNet will promptly
assign an individual who will: (i) oversee and manage the performance of the
Integration Services (this includes the responsibility to see that all
milestones are met on-time and that all deliverables satisfy the requirements of
this Agreement); (ii) serve as PurchasePro's primary point of contact for
matters pertaining to the Integration; and (iii) have the authority to make
binding commitments on behalf of AuctioNet (the "AuctioNet Engagement Manager").

            (h) Upon the execution of this Agreement, PurchasePro will promptly
assign an individual who will serve as PurchasePro's primary point of contact
with AuctioNet for matters pertaining to the Integration (the "PurchasePro
Engagement Manager"). The PurchasePro Engagement Manager will be responsible and
authorized to: (i) serve as AuctioNet's primary point of contact for matters
pertaining to the Integration; (ii) have the authority to make binding
commitments on behalf of PurchasePro; (iii) approve modifications to the
Integration Plan; and (iv) accommodate reasonable requests by the AuctioNet
Engagement Manager for PurchasePro information, data and support of a type
specified in the Integration Plan or reasonably required by AuctioNet for its
performance of the Integration Services.

            (i) The Integration shall be governed by an oversight committee
("Oversight Committee") composed of an equal number of people from each Party,
including the AuctioNet Engagement Manager, the PurchasePro Engagement Manager,
AuctioNet's Chief Technology Officer, and PurchasePro's Chief Technology Officer
and such other persons as may be designated by such individuals. The Oversight
Committee shall have the power to resolve all disputes arising with respect to
the Integration by affirmative vote of its members. In the event the Oversight
Committee is unable to resolve any particular dispute within a reasonable time
period, such dispute shall be submitted to one senior manager of each party for
resolution by mutual agreement within ten (10) business days. Failing such
resolution, such dispute shall be submitted to one executive officer of each
party for resolution by mutual agreement within thirty (30) calendar days.
Failing resolution by the parties' executive officers, the dispute shall be
submitted to arbitration in accordance with Section 13.3.

            (j) PurchasePro acknowledges that AuctioNet may subcontract the
performance of the Integration Services to third parties on a partial basis. In
such event, AuctioNet will remain fully responsible in all respects to
PurchasePro for the performance of the Integration Services in accordance with
the terms of this Agreement, and will be deemed for the

                                      -8-

Trademark of the other Party. Notwithstanding the foregoing, PurchasePro shall
discontinue all use of AuctioNet Trademarks if the Integrated Software includes
any PurchasePro Modification and AuctioNet objects to such use because in its
reasonable discretion such Modification degrades the performance of the Software
or the Integrated Software or the experience of a user of the AuctioNet Services
as would constitute a material adverse effect with respect thereto, and further,
such Modification has not been approved by AuctioNet.

      6.2  Promotion Materials and Activities. All representations of the other
Party's Trademarks that a Party intends to use shall be exact copies of those
used by the other Party and shall first be submitted to the originating Party

business of the other. All goodwill associated with the use of each Party's
Trademarks shall inure exclusively to the owner of such Trademarks.

services.

      7.1  No Conflict. Each Party represents and warrants to the other Party
that it is under no current obligation or restriction, nor will it knowingly

property rights of a third party.

      7.3  Product Warranty. AuctioNet warrants that the Integrated Software
will perform in accordance with the requirements set forth in the Integration

replace such Software free of charge.

      7.4  Virus Warranty. AuctioNet warrants to PurchasePro that it has tested
the Software to ensure that the Software does not contain any virus or other

PurchasePro Customer arising out of or in connection with claims that the
Software or Integrated Software (excluding any PurchasePro Modification)
infringes any patent, copyright, trademark or trade right secret of a third
party, provided that PurchasePro (a) promptly gives written notice to AuctioNet
of any such claim or action, and (b) gives AuctioNet the right to control and
fully cooperates with AuctioNet in the defense of such claim or action,. If the
Software or the Integrated Software is, or in the opinion of AuctioNet may
become, the subject of any claim of infringement or if it is adjudicatively
determined that the Software or the Integrated Software infringes the rights of
any third party, then AuctioNet may, at its sole option and expense, either (a)
procure for PurchasePro the right from such third party to use the Software or
the Integrated Software, or (b) replace or modify the Software or Integrated
Software with other suitable and substantially equivalent products so that the
Software or Integrated Software, as applicable, becomes non-infringing. This

                        MAINTENANCE AND SUPPORT SERVICES

AuctioNet will provide Level 1 Support to PurchasePro Customers requesting
assistance. A transition program, including training and procedures, will be in
place for PurchasePro/NetBusiness B2B marketplace customer support to handle

foregoing, PurchasePro may at its option provide all Level 1 Support directly to
PurchasePro Customers.

Software and/or problems related to the hosted physical infrastructure or
functionality.

PurchasePro shall use all commercially reasonable efforts to promptly provide
AuctioNet with notification of bugs encountered in the Software.

                                    EXHIBIT C

                                      FEES

PurchasePro shall pay to AuctioNet a total of $5,000,000 of which (i) $3,000,000
will constitute fees for the licenses granted in Section 2 and will be due and
payable upon the execution of this Agreement by both Parties hereto; and (ii)
the remaining $2,000,000 will constitute fees for the services by AuctioNet
pursuant to Section 5 (of which $1,000,000 will constitute fees for the
Integration Services ("Integration Fee")) and will be paid in Twenty-Four (24)
equal monthly installments (each, a "Monthly Installment") on the 1st of each
month, commencing on February 1, 2001 and with the last payment due on January
1, 2003.

Notwithstanding the foregoing, in the event that either (i) the Integration Plan
is not approved by PurchasePro pursuant to Section 5.2(c) by March 15, 2001 or
(ii) the Integration is not completed in a timely manner in accordance with the
time schedule set forth in the PurchasePro-approved Integration Plan, for each
and every month the Integration Plan is not approved or that Integration is not
completed in a timely manner, as applicable, the portion of the Monthly
Installment (then due and owing upon the expiration of such month) representing
the Integration Fee shall be deemed deferred by AuctioNet. Further, PurchasePro
shall no longer be obligated to pay the same for performance which is more than
ninety (90) days late. No amount shall be deemed waived or deferred by AuctioNet
if AuctioNet can reasonably demonstrate that PurchasePro unreasonably withheld
approval of the Integration Plan or that failure to complete the Integration on
a timely manner was the result of an act or failure to act by PurchasePro or the
occurrence of a force majeure event or condition stated in Section 13.7 of the
Agreement.

                                    EXHIBIT D

                                 SERVICE LEVELS

1.    Site Infrastructure. AuctioNet will be responsible for all communications,
      hosting and connectivity costs and expenses associated with the
      AuctioNet's site. AuctioNet will provide all hardware, software,
      telecommunications lines and other infrastructure necessary to meet
      traffic demands on the AuctioNet Site from the PurchasePro global
      marketplace. AuctioNet will design and implement the network between the
      PurchasePro global marketplace and AuctioNet site such that (i) no single
      component failure will have a materially adverse impact on PurchasePro
      Customers seeking to reach the AuctioNet site from the PurchasePro global
      marketplace and (ii) no single line under material control by AuctioNet
      will run at more than 70% average utilization for a 5-minute peak in a
      daily period. In this regard, AuctioNet will provide PurchasePro, upon
      request, with a detailed network diagram regarding the architecture and
      network infrastructure supporting the AuctioNet site. In the event that
      AuctioNet elects to create a custom version of the AuctioNet site in order
      to comply with the terms of this Agreement, AuctioNet will bear
      responsibility for all aspects of the implementation, management and cost
      of such customized site.

2.    Optimization; Speed. AuctioNet will use commercially reasonable efforts to
      ensure that: (a) the functionality and features within the AuctioNet site
      are optimized for the client software then in use by PurchasePro
      Customers; and (b) the AuctioNet Site is designed and populated in a
      manner that minimizes delays when PurchasePro Customers attempt to access
      such site. At a minimum, AuctioNet will ensure that the AuctioNet site's
      data transfers initiate within fewer than fifteen (15) seconds on average.
      Prior to commercial launch of any material promotions described herein,
      AuctioNet will permit PurchasePro to conduct performance and load testing
      of the AuctioNet site (in person or through remote communications), with
      such commercial launch not to commence until such time as PurchasePro is
      reasonably satisfied with the results of any such testing.

3.    User Interface. AuctioNet will maintain a graphical user interface within
      the AuctioNet site that is competitive in all material respects with
      interfaces of other similar sites based on similar form technology.
      PurchasePro reserves the right to review and approve the user interface
      and site design prior to launch of the Integrated Software and to conduct
      focus group testing to assess compliance with respect to such consultation
      and with respect to AuctioNet's compliance with the preceding sentence.

4.    Technical Problems. AuctioNet agrees to use commercially reasonable
      efforts to address material technical problems (over which AuctioNet
      exercises control) affecting use by PurchasePro Customers of the AuctioNet
      site (an "AuctioNet Technical Problem") promptly following notice thereof.
      In the event that AuctioNet is unable to promptly resolve an AuctioNet
      Technical Problem following notice thereof from PurchasePro (including,
      without limitation, infrastructure deficiencies producing user delays),
      PurchasePro will have the right to regulate the promotions it provides to
      AuctioNet hereunder until such time as AuctioNet corrects the AuctioNet
      Technical Problem at issue.

5.    Monitoring. AuctioNet will ensure that the performance and availability of
      the AuctioNet site is monitored on a continuous basis. AuctioNet will
      provide PurchasePro with contact information (including e-mail, phone,
      pager and fax information, as applicable, for both during and after
      business hours) for AuctioNet's principal business and technical
      representatives, for use in cases when issues or problems arise with
      respect to the AuctioNet site.

6.    Telecommunications. Where applicable AuctioNet will utilize encryption
      methodology to secure data communications between the

                                      -19-
<PAGE>

      Parties' data centers. The network between the Parties will be configured
      such that no single component failure will significantly impact
      PurchasePro Customers.

7.    Security. AuctioNet will utilize Internet standard encryption technologies
      (e.g., Secure Socket Layer - SSL) to provide a secure environment for
      conducting transactions and/or transferring private member information
      (e.g. credit card numbers, banking/financial information, and member
      address information) to and from the AuctioNet site. AuctioNet will
      facilitate periodic reviews of the AuctioNet site by PurchasePro in order
      to evaluate the security risks of such site. AuctioNet will promptly
      remedy any security risks or breaches of security as may be identified by
      PurchasePro.

8.    Technical Performance.

      (i)   AuctioNet will design the AuctioNet site to support the
            PurchasePro-client embedded versions of the Microsoft Internet
            Explorer 4.XX, 5.XX and 6.XX browsers (Windows and Macintosh) and
            the Netscape Browser 4.XX and 6.XX and make commercially reasonable
            efforts to support all other browsers designated by PurchasePro.

      (ii)  To the extent AuctioNet creates customized pages on the AuctioNet
            site for PurchasePro Customers, AuctioNet will develop and employ a
            methodology to detect PurchasePro Customers.

      (iii) AuctioNet will periodically review the technical information made
            available by PurchasePro.

      (iv)  AuctioNet will design its site to support HTTP 1.0 or later protocol
            as defined in RFC 1945 and to adhere to PurchasePro's parameters for
            refreshing or preventing the caching of information in PurchasePro's
            proxy system as outlined by PurchasePro.

      (v)   Prior to releasing material, new functionality or features through
            the AuctioNet site ("New Functionality"), AuctioNet will use
            commercially reasonable efforts to (i) test the New Functionality to
            confirm its compatibility with PurchasePro service client software,
            and (ii) provide PurchasePro with written notice of the New
            Functionality so that PurchasePro can perform tests of the New
            Functionality to confirm its compatibility with the PurchasePro
            service client software. Should any new material, new functionality
            or features through the AuctioNet site be released without
            notification to PurchasePro, PurchasePro will not be responsible for
            any adverse member experience until such time that compatibility
            tests can be performed and the new material, functionality or
            features qualified for the PurchasePro service.

9.    PurchasePro Internet Services Support. PurchasePro will provide AuctioNet
      with access to the standard online resources, standards and guidelines
      documentation, technical phone support, monitoring and after-hours
      assistance that PurchasePro makes generally available to similarly
      situated web-based partners. PurchasePro support will not, in any case, be
      involved with content creation on behalf of AuctioNet or support for any
      technologies, databases, software or other applications which are not
      supported by PurchasePro. Support to be provided by PurchasePro is
      contingent on AuctioNet providing to PurchasePro demo account information
      (where applicable), a detailed description of the AuctioNet site's
      software, hardware and network architecture and access to the AuctioNet
      site for purposes of such performance and load testing as PurchasePro
      elects to conduct.
