                        BULK SUBSCRIPTION SALES AGREEMENT

      This Bulk Subscription Sales Agreement ("Agreement") is entered into as of
the 1st day of December, 2000, by and between PurchasePro.com, Inc.
("PurchasePro") and America Online, Inc. ("AOL").

      WHEREAS, the Parties are currently jointly developing an e-commerce
marketplace for subscribers to the services of AOL and its affiliates, including
its Netscape subsidiary ("Subscribers") for use in conjunction with
PurchasePro's global marketplace (the "Global Marketplace"); and

      WHEREAS, to encourage use of the e-marketplace being jointly developed by
the Parties by Subscribers, AOL desires to purchase on behalf of such
Subscribers subscriptions to the Global Marketplace with full access for
Subscribers to all rights and benefits available to members of the Global
Marketplace, a description of which is attached hereto as Exhibit B;

      NOW, THEREFORE, the parties hereto hereby agree as follows:

      1. Bulk Subscriptions. Subject to the terms and conditions set forth
herein, AOL hereby purchases from PurchasePro, and PurchasePro sells to AOL, a
sufficient number of subscriptions to the Global Marketplace ("Promotional
Subscriptions") for AOL to allocate among Subscribers as AOL determines in its
sole discretion, at a price of $49.00 per Subscriber per month. A Promotional
Subscription shall provide Subscribers with access to rights and benefits at
least a great as to any other PurchasePro premium marketplace service. Without
limiting the foregoing and at a minimum, Subscribers receiving Promotional
Subscriptions shall have access to all of the services set forth on Exhibit B.
After the Promotional Period (as defined below), PurchasePro shall, in an opt-in
format reasonably acceptable to AOL, offer Subscribers the opportunity to
continue with the premium membership referenced in Exhibit B at PurchasePro's
standard rates. PurchasePro shall provide all Subscribers, including holders of
the premium membership or a standard membership, with all telephone and online
customer support available to other members holding the same or similar
memberships.

      2. Schedule of Purchases. AOL shall purchase 100,000 Promotional
Subscriptions to the Global Marketplace hereunder for the period between
December 1, 2000 and December 31, 2000, and shall have the option to purchase
Promotional Subscriptions to the Global Marketplace for additional monthly
periods upon notice to PurchasePro no later than 5 days after the beginning of
such monthly period (all such monthly periods shall be referred to herein
collectively as the "Promotional Period").

3.    Distribution of Promotional Subscriptions Sharing of Subscription Fee
      Revenue. The Parties acknowledge that AOL will offer the Promotional
      Subscriptions to the Global Marketplace to Subscribers. The Parties agree
      that after the initial two month free subscription period (or such large


                                      -1-
<PAGE>

      period as mutually agreed by the Parties) included as part of such
      Promotional Subscriptions, AOL shall have no liability for any
      subscription fee (subscription fees collected from Promotional Subscribers
      shall be referred to herein as "Subscription Fee Revenue"). After the
      Promotional Period, PurchasePro shall pay AOL in perpetuity fifty (50%)
      percent of all Subscription Fee Revenue received and owed to AOL as
      described herein and paid on a quarterly basis within thirty (30) days
      following the end of the quarter in which such amounts were generated. All
      payments shall be accompanied by a report in a format and substance
      reasonably acceptable to AOL setting forth all relevant financial
      information supporting such payment.

4.    Term. The term of this Agreement shall commence as of the date hereof and
      continue until January 31, 2001; provided that Section 3 and 7 and the
      provisions set forth in Section 7 of Exhibit A shall survive any
      termination hereof

5.    Obligations.

      A.    At such times as AOL shall determine, AOL shall notify Subscribers
            selected by AOL that such Subscribers have been chosen to receive a
            Promotional Subscription to the Global Marketplace hereunder and
            become a full Member thereon for the periods set forth in Section 2.
            AOL may notify its Subscribers thereof in any manner determined by
            AOL in its sole discretion, including notification by transmission
            of e-mails thereto.

      B.    PurchasePro shall make available user ID's and passwords for each
            such Subscribers selected by AOL necessary to access the Global
            Marketplace, coded to identify such users as a Subscriber and Member
            of the AOL-branded marketplace on the Global Marketplace. Any
            PurchasePro messaging to Promotional Subscribers during the
            Promotional Period shall be subject to AOL's prior approval, which
            approval shall not be unreasonably withheld, conditioned or delayed.

6.    Manner and Method of Payment to PurchasePro. For each month during the
      Promotion Period with respect to which AOL is purchasing Promotional
      Subscriptions pursuant to Section 2 hereunder, AOL shall pay $4,900,000 to
      PurchasePro, due on or before the last day of such month. In no event
      shall AOL's liability for the purchase of Promotional Subscriptions
      hereunder in any one month during the Promotional Period exceed a total of
      four million nine hundred thousand dollars ($4,900,000) for such month.

7.    Auditing Rights. PurchasePro will maintain complete, clear and accurate
      records of all expenses, revenues and fees in connection with the
      performance of this Agreement. For the sole purpose of ensuring compliance
      with this Agreement, AOL (or its representative) will have the right to
      conduct a reasonable and necessary inspection of portions of the books and
      records of PurchasePro which are relevant to PurchasePro's performance
      pursuant to this Agreement. Any such audit may be conducted after 20

<PAGE>

      business days prior written notice is given by AOL to Purchase Pro;
      provided, however, that such audits may not be conducted more than once in
      any given twelve (12) month period and the same time period may not be
      audited more than once. The audit report and all of the books and records
      reviewed by AOL shall be Purchase Pro's Confidential Information. AOL
      shall bear the expense of any audit conducted pursuant to this Section 7
      unless such audit shows an error in AOL's favor amounting to a deficiency
      to AOL in excess of 5% of the actual amounts paid and/or payable to it
      under this Agreement, in which event Purchase Pro shall bear the
      reasonable expenses of the audit. Purchase Pro shall pay AOL the amount of
      any deficiency or AOL shall pay Purchase Pro the amount of any overpayment
      finally determined as a result of such audit within 30 days after such
      final determination.

8.    Standard Terms and Condition. PurchasePro's Standard Marketplace Services
      Terms and Conditions, a copy of which is attached hereto as Exhibit A, are
      hereby incorporated herein by reference in their entirety. In the event of
      any conflict between this Agreement and such Standard Marketplace Services

Marketplace Services Standard Terms and Conditions

1. CONFIDENTIALITY. AOL agrees that the Marketplace Services described in the
agreement to which these Standard Terms and Conditions are attached
("Agreement"), and the Marketplace Software Product with respect to which the
Marketplace Services are being provided, are based upon proprietary information
which is the exclusive property of and owned by PurchasePro and are treated as
confidential ("Confidential Information"). AOL shall, and shall cause its
employees and agents to, strictly maintain the confidentiality of the
Confidential Information and not disclose, disseminate or otherwise give
Confidential Information to any other person, firm, organization or third party,
except for an employee or agent of AOL who has a reasonable need to obtain
access thereto in connection with the establishment and operation of AOL's
Marketplace and who has agreed in writing to not disclose, and not to use for
any other purpose, the Confidential Information. Notwithstanding the foregoing,
the obligations of confidentiality set forth in this Section 1 with respect to
Confidential Information shall not apply to any information that: (i) is or
becomes publicly known without violation by AOL of the Agreement; (ii) is
already known to AOL without restrictions at the time of its disclosure by
PurchasePro, as evidenced by the written records of AOL; (iii) after its
disclosure to AOL by PurchasePro, is made known to AOL without restrictions by a
third party having the right to do so; or (iv) is legally required to be
disclosed by AOL pursuant to a judicial order from a court of competent
jurisdiction (provided that AOL promptly informs PurchasePro of the requirement
and affords PurchasePro a reasonable opportunity to contest the required
disclosure). AOL's obligations under this Section 1 shall survive expiration or
termination of the Agreement for any reason.

2. LIMITED WARRANTIES, INDEMNITY AND DISCLAIMER. PurchasePro warrants and
represents that it has full title and ownership of intellectual property
delivered in conjunction with the Marketplace Services and has the full power
and authority to perform its obligations under the Agreement. PurchasePro will
defend AOL from and against any claim or action brought against AOL alleging
that its performance of the Marketplace Services infringe any valid U.S. patent,
copyright, trade secret or proprietary right of a third party, provided that AOL
(a) promptly gives written notice to PurchasePro of any such claim or action,
(b) gives PurchasePro the right to control and fully cooperates with PurchasePro
in the defense of such claim or action, (c) has not made or caused to be made
any modifications to the Marketplace Services, and (d) has not used the
Marketplace Services other than as specified in the Agreement or in any
documentation delivered in connection with the Marketplace Software Product, and
PurchasePro will pay any final award of damages against AOL resulting from such
claim or action, including any attorneys fees and costs awarded, or any
settlement amount agreed to by PurchasePro. AOL's sole and exclusive remedy for
any breach of warranty shall be commercially reasonable efforts to correct the
non-conformity or, if incapable of being corrected, termination of the Agreement
and refund of any consideration paid by AOL pursuant to the Agreement. EXCEPT AS
EXPRESSLY PROVIDED HEREIN, THE MARKETPLACE SERVICES ARE PROVIDED TO AOL "AS IS",
PURCHASEPRO MAKES NO WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, REGARDING THIS
AGREEMENT OR THE MARKETPLACE SERVICES AND, TO THE MAXIMUM EXTENT PERMITTED BY
LAW, SPECIFICALLY DISCLAIMS ANY WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A
PARTICULAR PURPOSE OR AGAINST INFRINGEMENT, AND THE FOREGOING STATES
PURCHASEPRO'S ENTIRE LIABILITY AND AOL'S SOLE AND EXCLUSIVE REMEDY FOR ANY
BREACH OF WARRANTY.

3. ASSIGNABILITY. AOL may not assign the Agreement, whether by operation of law
or otherwise, without the prior written consent of PurchasePro, not to be
unreasonably withheld. For purposes of the foregoing, any conveyance or other
transfer of any capital securities of AOL, or any other transaction whatsoever,
the effect of which is to confer upon the recipient or recipients thereof the
ability to determine a majority of members of AOL's board of directors or
otherwise control the affairs of AOL shall be deemed an assignment hereunder.

4. OWNERSHIP OF INTELLECTUAL PROPERTY. AOL understands and agrees that
PurchasePro owns and retains all right, title and interest in any services,
software products, intellectual property rights, source code, documentation, any
future modifications and all related materials that may be provided under the
terms of the Agreement.

5. OWNERSHIP AND USE OF DATA. Information obtained from AOL Users (as defined in
that certain Interactive Marketing Agreement, dated as of March 15, 2000,
referred to herein as the "IMA") shall be deemed User Information under section
13 of Exhibit F of the IMA and shall be governed by such Section.

6. TERMINATION UPON DEFAULT. If either party shall violate or breach any
material term, condition or covenant contained herein and shall not remedy such
violation or breach within thirty (30) days after receipt of written notice
thereof from the other party, the party not in violation or breach may terminate
this Agreement, effective immediately upon written notice to the party in
violation or breach.

7. EFFECT OF EXPIRATION OR TERMINATION. The following Sections shall survive any
expiration or termination of this Agreement: Sections 1, 2, 4, 5, 6, 7, 8, 10,
11 and 13.

8. RESOLUTION OF DISPUTES. Disputes arising under this Agreement shall be
resolved in accordance with the dispute resolution procedures set forth in
Section 8 of the IMA.

9. FORCE MAJEURE. Each party to the Agreement shall be excused from any delay or
failure in its performance thereunder, other than for payment of money, caused
by any disruption or slow speed of the Internet, break-downs of security or
introduction of computer viruses (and the like) by third parties, any labor
dispute, government requirement, act of God, or any other cause beyond its
control. Such party shall use best efforts to cure any such failure or delay in
performance arising from a force majeure condition, and shall timely advise the
other party of such efforts. If such delay continues for more than ten (10)
days, the party injured by the inability of the other to perform may upon ten
(10) days prior written notice terminate the Agreement.

10. LIMITATIONS ON LIABILITY. NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY
FOR ANY CONSEQUENTIAL, INDIRECT, SPECIAL, PUNITIVE OR EXEMPLARY DAMAGES OF ANY
KIND OR AMOUNT, REGARDLESS OF LEGAL THEORY (INCLUDING TORT, BREACH OF CONTRACT
OR STRICT LIABILITY) ARISING OUT OF OR IN CONNECTION WITH THE AGREEMENT. THE
