         SECTION 2. EXERCISE OF WARRANT.

         2.1.  EXERCISE.

         (a) This Warrant may be exercised by the Holder during the Warrant
Exercise Period at any time or from time to time, in whole or in part, by
surrender of this Warrant, with the form of subscription attached as EXHIBIT A
hereto duly executed by the Holder, to the Company at its principal office,
accompanied by payment in cash by certified or official bank check payable to
the order of the Company or by wire transfer to its account, in the amount
obtained by multiplying the number of Shares for which this Warrant is then
being exercised by the Exercise Price then in effect.

         (b) In the event the Warrant is not exercised in full, the Company,
at its expense, will forthwith issue and deliver to or upon the order of the
Holder a new Warrant or Warrants of like tenor, in the name of the Holder or
as the Holder (upon payment by the Holder of any applicable transfer taxes)
may request, calling in the aggregate on the face or faces thereof for the
number of Shares equal (without giving effect to any adjustment therein) to
the number of such Shares called for on the face of this Warrant minus the
number of such Shares (without giving effect to any adjustment therein) for
which this Warrant shall have been exercised.

         2.2. EARLY EXERCISE RIGHTS. For each measuring period set forth on
SCHEDULE 1 attached hereto (each a "MEASURING PERIOD"), the Holder will earn the
right to exercise this Warrant for a number of Shares equal to the product of
(i) 1.51778532 multiplied by (ii) the number of whole tons of Newsprint and
other paper products that the Holder purchases or sells through the Company's
web site exchange during such Measuring Period up to the maximum number of whole
tons of Newsprint and other paper products set forth on SCHEDULE 1 for such
Measuring Period, subject to adjustment as provided in the next sentence and in
Sections 6 and 7. Paper products other than Newsprint shall be counted toward
the maximum aggregate metric

<PAGE>
                                      -4-

tons shown as SCHEDULE 1 as follows: as and to the extent that non-Newsprint
paper products are purchased or sold by Bowater through the Company's web site
exchange during a Measuring Period, Bowater shall get a credit in tons toward
the maximum aggregate tons shown on SCHEDULE 1 proportionately adjusted to
reflect the difference in the per-ton price for such other paper product and the
per-ton price for Newsprint. The right described in this Section 2.2 shall be
referred to as the "EARLY EXERCISE RIGHT." The Holder shall also have the
opportunity to earn the Early Exercise Right as follows: if the Holder has
listed the minimum tonnage of Newsprint and/or other paper products (adjusted as
described above) set forth on SCHEDULE 1 at any time during a Measuring Period,
for purposes of determining whether or not it has earned the Early Exercise
Right for that Measuring Period, the Holder can carry forward from, but only
from, the immediately preceding Measuring Period the amount by which actual
aggregate tons of Newsprint and other paper products (adjusted as described
above) sold or purchased, if any, during such immediately preceding Measuring
Period exceeded the maximum aggregate metric tons shown on SCHEDULE 1 for such
immediately preceding Measuring Period. For each consecutive eight (8) hours
that the Company's web site is not capable of listing and executing actual
transactions related to Newsprint in a manner not materially adversely different
from the capability of the Company's website as of the date hereof with respect
to the containerboard and printing and writing components of the Company's
website, the dates on SCHEDULE 1 occurring on or after such event shall be
extended by two (2) business days. The Warrant Shares as to which the Holder has
earned any Early Exercise Right may be purchased during the Warrant Exercise
Period for such rights; provided that any Early Exercise Right earned pursuant
to this Section 2.2 shall terminate on the fifth anniversary of the last day of
the Measuring Period for which such right was earned (the "EARLY EXPIRATION
DATE") unless exercised in full prior thereto. Once the Holder has earned the
Early Exercise Right described in this Section with respect to any Warrant
Shares, the anti-dilution provisions set forth in Sections 6 and 7 of this
Agreement shall operate as to those Warrant Shares, even if the event triggering
the operation of the anti-dilution provision has already occurred.

         2.3. EXPIRATION. This Warrant shall terminate upon the earlier to occur
of (i) exercise in full, (ii) the Early Expiration Date with respect to, but
only with respect to, any Shares for which the right to early exercise was
earned pursuant to Section 2.2 and (iii) May 5, 2015 (the "WARRANT EXPIRATION
DATE").

         SECTION 3. REGISTRATION RIGHTS. The Holder understands that (i) this
Warrant and the Shares issuable upon exercise of this Warrant have not been
registered under the 1933 Act by reason of their issuance in a transaction
exempt from the registration requirements of the 1933 Act, (ii) this Warrant and
the Shares issuable upon exercise of this Warrant must be held indefinitely
unless a subsequent disposition thereof is registered under the 1933 Act and
applicable state securities laws or is exempt from such registration (and, upon
request, evidence satisfactory to the Company is provided by the Holder of the
availability of such exemptions, including, upon request, the delivery to the
Company of opinions of counsel to the Holder, which opinions of counsel are
satisfactory to the Company), and (iii) this Warrant and the Shares issuable
upon exercise of this Warrant may bear a legend to such effect.

         SECTION 4. NO FRACTIONAL SHARES OR SCRIP. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise or conversion
of this Warrant or any portion thereof. With respect to any fraction of a share
called for upon the exercise or conversion of this Warrant or any portion
thereof, an amount equal to such fraction multiplied by the then current Fair
Market Value of a Warrant Share shall be paid to the Holder in cash by the
Company.

                                      -5-

         SECTION 5. CHARGES, TAXES AND EXPENSES. Issuance of Warrant Shares upon
the exercise or conversion of this Warrant or any portion thereof shall be made
without charge to the Holder for any issue or transfer taxes or any other
incidental expenses in respect of the issuance of such Warrant Shares, all of
which taxes and expenses shall be paid by the Company, and such Warrant Shares
shall be issued in the name of the Holder; PROVIDED, HOWEVER, that any income
taxes or capital gains taxes or similar taxes assessed with respect to the
Warrant Shares following their issuance to the Holder shall be payable by the
Holder.

         SECTION 6. ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC.

              6.1. CERTAIN ADJUSTMENTS. With respect to, but only with respect
     to, any Shares for which the right to early exercise was earned pursuant to
     Section 2.2, in case at any time or from time to time during the period
     commencing on the Issue Date and ending on the Early Expiration Date for
     such Shares (the "ADJUSTMENT PERIOD"), the Company shall (a) effect a
     capital reorganization, reclassification or recapitalization, (b)
     consolidate with or merge into any other entity, or (c) transfer all or
     substantially all of its properties or assets to any other entity under any
     plan or arrangement contemplating the dissolution of the Company, then in
     each such case, the Holder, on the exercise hereof as provided in Section 2
     hereof at any time after the consummation of such reorganization,
     reclassification, recapitalization, consolidation or merger or the
     effective date of such dissolution, as the case may be, shall receive, in
     lieu of the Shares (or Other Securities) issuable on such exercise prior to
     such consummation or effective date, the Shares and Other Securities and
     property (including cash) to which the Holder would have been entitled upon
     such consummation or in connection with such dissolution, as the case may
     be, if the Holder had so exercised this Warrant immediately prior thereto,
     all subject to further adjustment thereafter as provided in Section 7
     hereof.

              6.2. CONTINUATION OF TERMS. Upon any reorganization,
     consolidation, merger or transfer (and any dissolution following any
     transfer) during the Adjustment Period and referred to in this Section 6,
     this Warrant shall continue in full force and effect and the terms hereof
     shall be applicable to the Shares and Other Securities and property
     receivable on the exercise of this Warrant after the consummation of such
     reorganization, reclassification, recapitalization, consolidation or merger
     or the effective date of dissolution following any such transfer, as the
     case may be, and shall be binding upon the issuer of any such Shares or
     Other Securities, including, in the case of any such transfer, the Person
     acquiring all or substantially all of the properties or assets of the
     Company, whether or not such Person shall have expressly assumed the terms
     of this Warrant as provided in Section 8 hereof.

         SECTION 7. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES. The
Exercise Price and number of Shares issuable upon exercise or conversion hereof
shall be subject to adjustment from time to time at any time after the Issue
Date as follows:

              7.1. ADJUSTMENTS FOR DISTRIBUTIONS OF SHARES OR OTHER SECURITIES,
     SPLITS AND COMBINATIONS. With respect to, but only with respect to, any
     Shares for which the right to early exercise was earned pursuant to Section
     2.2, in case at any time or from time to time during the Adjustment Period,
     the Company shall (a) issue any Shares or Other Securities as a dividend or
     distribution, or (b) issue any Shares or Other Securities in subdivision of
     outstanding Shares or Other Securities by reclassification or otherwise,
     then the then current number and type of Warrant Shares issuable

<PAGE>
                                      -6-

     upon exercise or conversion hereof shall be adjusted to a number and type
     equal to the number and type of Warrant Shares issuable upon exercise
     immediately prior to such event plus the number and type of Warrant Shares
     the Holder would have received had the Holder exercised this Warrant
     immediately prior to such event and received the number and type of Shares
     and Other Securities issued in connection with such event and the Exercise
     Price shall be adjusted to an amount equal to the Total Exercise Price (or,
     if this Warrant has previously been exercised in part, the remaining unpaid
     portion of the Total Exercise Price) divided by the total number of Warrant
     Shares issuable upon exercise of this Warrant after giving effect to this
     adjustment. In case at any time or from time to time the Company shall
     combine outstanding Shares or Other Securities by reclassification or
     otherwise, then the then current number and type of Warrant Shares issuable
     upon exercise or conversion hereof shall be adjusted to a number and type
     equal to the number and type of Warrant Shares the Holder would have
     received had the Holder exercised this Warrant immediately prior to such
     event and received the number and type of Shares issued in connection with
     such event and the Exercise Price shall be adjusted to an amount equal to
     the Total Exercise Price (or, if this Warrant has previously been exercised
     in part, the remaining unpaid portion of the Total Exercise Price) divided
     by the total number of Warrant Shares issuable upon exercise of this
     Warrant after giving effect to this adjustment.

              7.2. RECORD OF HOLDERS. In case the Company shall take a record of
     the holders of its Shares for the purpose of entitling them (a) to receive
     a dividend or other distribution payable in Shares or Other Securities, or
     (b) to subscribe for or purchase Shares or Other Securities, then such
     record date shall be deemed to be the date of the issue or sale of the
     Shares or Other Securities deemed to have been issued or sold upon the
     declaration of such dividend or the making of such other distribution or
     the date of the issue of such right of subscription or purchase, as the
     case may be.

         SECTION 8. NO DILUTION. The Company will not, by amendment of its
Certificate of Incorporation, or through any reorganization, transfer of assets,
consolidation, merger or dissolution, avoid or seek to avoid the observance or
performance of any of the terms of this Warrant. Without limiting the generality
of the foregoing, the Company (a) will take all such action as may be necessary
or appropriate in order that the Company may validly and legally issue fully
paid and non-assessable Shares on the exercise of the Warrant from time to time,
and (b) will not transfer all or substantially all of its properties and assets
to any other entity, or consolidate with or merge into any other entity or
permit any such entity to consolidate with or merge into the Company, unless
such other entity shall expressly assume in writing and will be bound by all the
terms of this Warrant.

         SECTION 9. ACCOUNTANTS' CERTIFICATE AS TO ADJUSTMENTS. In the case of
each event that may require any adjustment or readjustment in the Warrant Shares
issuable on the exercise of this Warrant, the Company at its expense will
promptly prepare a certificate setting forth such adjustment or readjustment, or
stating the reasons why no adjustment or readjustment is being made, and
showing, in detail, the facts upon which any such adjustment or readjustment is
based, including a statement of (a) the number of shares of each class of the
Company's Common Stock then outstanding on a fully diluted basis, and (b) the
number of shares of each class of Warrant Shares to be received upon exercise of
this Warrant, in effect immediately prior to such adjustment or readjustment and
as adjusted and readjusted (if required by Section 6 or Section 7) on account
thereof. The Company will forthwith mail a copy of each such certificate to each
holder of a Warrant, and will, on the written request at any time of any holder
of a Warrant, furnish to such holder a like certificate setting forth the
calculations used to determine such adjustment or readjustment. At its option,
the holder of a Warrant may confirm the adjustment noted on the

<PAGE>
                                      -7-

certificate by causing such adjustment to be computed by an independent
certified public accountant at the expense of the Company.

         SECTION 10.       NOTICES OF RECORD DATE.  In the event of:

                  (a) any taking by the Company of a record of the holders of
         any class of securities for the purpose of determining the holders
         thereof who are entitled to receive any dividend or other distribution,
         or any right to subscribe for, purchase or otherwise acquire any shares
         of stock or other securities of any class or property, or to receive
         any other right; or

                  (b) any capital reorganization of the Company, any
         reclassification or recapitalization of the capital stock of the
         Company or any transfer of all or substantially all the assets of the
         Company to or any consolidation or merger of the Company with or into
         any other Person; or

                  (c) any voluntary or involuntary dissolution, liquidation or
         winding-up of the Company,

then, in each such event occurring during the Adjustment Period, the Company
will mail or cause to be mailed to the Holder, no later than three days prior
to such event, a notice specifying (a) the date on which any such record is
to be taken for the purpose of such dividend, distribution or right, and
stating the amount and character of such dividend, distribution or right, and
(b) the date on which any such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation
or winding-up is anticipated to take place, and the time, if any is to be
fixed, as of which the holders of record of Shares (or Other Securities)
shall be entitled to exchange their Shares (or Other Securities) for
securities or other property deliverable on such reorganization,
reclassification, recapitalization, transfer, consolidation, merger,
dissolution, liquidation or winding-up.

         SECTION 11. RESERVATION OF SHARES ISSUABLE ON EXERCISE OF WARRANT.
Sufficient shares of authorized but unissued Common Stock of the Company have
been reserved by appropriate action in connection with the prospective exercise
of the Warrant. The Company represents and warrants that the issuance of the
Warrant or the Warrant Shares will not require any further action by the
stockholders of the Company, will not be subject to pre-emptive rights in any
present or future stockholders of the Company and will not conflict with any
provision of any agreement to which the Company is a party or by which it is
bound, and such Shares, when issued upon exercise of the Warrant in accordance
with their terms or upon such conversion, will be duly authorized, fully paid
and non-assessable and will be free and clear of any liens or encumbrances;
provided, however, that the Shares shall be subject to restrictions on transfer
under state and/or federal securities laws and pursuant to the terms of the
Stockholders' Agreement.

         SECTION 12. NO RIGHTS OR RESPONSIBILITIES AS STOCKHOLDER. This Warrant
neither entitles the Holder to any rights, nor subjects the Holder to any
responsibilities, as a stockholder of the Company other than such rights as are
obtainable upon exercise of this Warrant.

         SECTION 13. EXCHANGE. This Warrant is exchangeable, upon the surrender
hereof by the registered holder at the principal office of the Company, for new
warrants of like tenor and date representing in the aggregate the right to
purchase the number of Warrant Shares purchasable hereunder, each of such new
warrants to represent the right to purchase such

<PAGE>
                                      -8-

number of Warrant Shares as shall be designated by said registered holder at the
time of such surrender.

         SECTION 14. LOSS, THEFT, DESTRUCTION OR MUTILATION OF WARRANT. Upon
receipt by the Company of evidence reasonably satisfactory to it of the loss,
theft, destruction or mutilation of this Warrant, and, in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it (which may
be the unsecured agreement of the Holder to indemnify the Company for any loss
on account thereof), and upon reimbursement to the Company of all reasonable
expenses incidental thereto, and upon surrender and cancellation of this
Warrant, if mutilated, the Company will make and deliver a new warrant of like
tenor and date, in lieu of this Warrant.

         SECTION 15. REMEDIES. The Company stipulates that the remedies at law
of the Holder in the event of any default or threatened default by the Company
in the performance of or compliance with any of the terms of this Warrant are
not and will not be adequate, and that such terms may be specifically enforced
by a decree for the specific performance of any agreement contained herein or by
an injunction against a violation of any of the terms hereof or otherwise.

         SECTION 16. TRANSFER OF WARRANT. Neither this Warrant nor the rights
hereunder are transferable by the Holder, provided that the Holder may transfer
this Warrant to a direct or indirect subsidiary owned 80% or more (with respect
to both voting and economic interests) by the Holder.

         SECTION 17. AMENDMENTS AND WAIVERS. Any term of this Warrant may be
amended only with the written consent of the Company and the Holder. Any
amendment or waiver effected in accordance with this Section 17 shall be binding
upon the Company and the Holder.

         SECTION 18. COMMUNICATIONS AND NOTICES. All communications and notices
hereunder must be in writing, either delivered in hand or sent by first-class
mail, postage prepaid, or sent by telecopier, and, if to the Company, shall be
addressed to it at the address set forth on the first page hereof, or at such
other address as the Company may hereafter designate in writing by notice to the
registered Holder, and, if to such registered Holder, addressed to such Holder
at the address of such Holder as shown on the books of the Company.

         SECTION 19. SUNDAYS, HOLIDAYS, ETC. If the last or appointed day for
the taking of any action required or the expiration of any right granted herein
shall be a Sunday or a Saturday or shall be a legal holiday or a day on which
banking institutions in Boston, Massachusetts are authorized or required by law
to remain closed, then such action may be taken or right may be exercised on the

("Specifications Phase") and may be amended from time to time as set forth
below.

2. INTEGRATION OF SERVICES.

      2.1 Overview. The goal of the parties is to implement a link on the Noosh
Site for end users of the Noosh Service that have been given the ability to
procure paper or print providers on the Noosh Service (collectively referred to
as "End Users") to procure and manage paper requisitions using the PEX Service
(provided that End Users with a pre-existing purchasing relationship for paper
with PEX may purchase paper directly from PEX without using the Noosh Service).

            2.1.1 Integration of Services. Noosh will use reasonable commercial
efforts to develop and integrate the Noosh Service with the PEX Service and PEX
will use reasonable commercial efforts to develop and integrate the PEX Service
with the Noosh Service to enable the following transactions on the Noosh
Service:

                  (a) When End Users specify the paper they want used for their
print jobs, the End Users will have the option to view available paper. When
this option is selected, the End Users will be linked to a list of matching
products (and/or close substitutes) available on the PEX site. This list will
include the price, availability, and other information that is normally provided
on the PEX site. In addition to viewing paper availability from PEX, the user
may have the ability to view paper availability from other sources but only
after having the option to view availability on the PEX site. Once matching
products on PEX are displayed, the End Users will then also have the option of
bidding on or purchasing this displayed product via PEX.

      2.2 (b) When End Users specify the paper they want used for their print
jobs, the End Users will also have the option of submitting an RFE for their
desired products on the PEX service. If End Users are able to submit an RFE to
paper procurement providers other than PEX, then the PEX Service will be listed
first and in no case an inferior format to other paper providers on the Noosh
site. If PEX receives an RFE through the Noosh Service, PEX shall respond to
such

                                        4
<PAGE>

RFE within the required time as specified in such RFE provided that if PEX fails
to respond within such time, PEX will be unable to participate in the RFE. If
the RFE becomes an Accepted Order (as defined in Section 7) on the Noosh
Service, PEX shall perform its obligations as set forth in such Accepted Order.
Similarly, if Noosh print providers receive an RFE for a print job via the Noosh
Service that does not already address paper procurement, the print provider will
be offered the option to submit an RFE for appropriate paper on the PEX Service.
Similarly, PEX will use reasonable commercial efforts to develop the ability for
a user of the PEX Service to obtain information available from the Noosh Service
of a similar importance and in a similar priority to other transactions
conducted by such user on the PEX service so that the user of the PEX Service
interacts with the Noosh Service in a way that is similar to the way an End User
interfaces with the PEX Service and information contained therein.

      2.3 Development Efforts. The parties shall use reasonable commercial
efforts to develop their respective Deliverables as defined in the
Specifications in accordance with the Development Schedule.

      2.4 Phases of Development. Development of the Deliverables shall take
place in two phases, which may overlap at the discretion of the parties.

            2.4.1 Specifications Phase. During Phase 1 (the "Specifications
Phase"):

                  (a) The parties will generate a mutually-agreeable Development
Schedule within forty-five (45) days after the Effective Date, which shall be
attached to this Agreement as Exhibit A (Development Schedule). The Development
Schedule is meant to serve as a guideline for the integration of Noosh Service
and PEX Services.

                  (b) Noosh will then generate, and PEX shall approve, the
Specifications in accordance with the milestones set forth in the Development
Schedule, and the Specifications shall be attached to this Agreement as Exhibit
B (Specifications). Noosh will define the Noosh APIs as part of the
Specification. (c) Any changes in the Development Schedule and Specifications
thereafter must be requested in writing by either party. If the requested change
is acceptable to both parties, Noosh will determine whether implementing the
suggested change would result in a delay or increase Noosh's costs to integrate
the PEX Service and will advise PEX on the effect of the suggested change. If
both parties accept the change and its effects on schedule and costs, the
applicable Exhibits will be modified to reflect the change and its effects.

                  (d) If the parties are unable to agree on the Development
Schedule and Specifications by August 1, 2000, Noosh or PEX may terminate the
Agreement with no liability for either party.

            2.4.2 Development Phase. Phase 2 (the "Development Phase") will
consist of:

                  (a) The parties' development and delivery of their respective
Deliverables in accordance with the Development Schedule and Noosh's reasonable
commercial

                                       5
<PAGE>

efforts to integrate the Deliverables into a paper procurement process on the
Noosh Site using the PEX Service.

                  (b) Noosh's acceptance testing of the Deliverables and the
overall paper procurement process using the PEX Service from the Noosh Site in
accordance with the acceptance test criteria in the Specifications. Unless the
parties otherwise agree with respect to a specific Deliverable, Noosh shall have
thirty (30) days following delivery of the final Deliverable to determine
whether the Deliverables as whole, and the overall paper procurement process
using the PEX Service, conform to the acceptance criteria (the "Initial
Acceptance Period"). Noosh agrees to inform PEX in writing during the Initial
Acceptance Period of any non-conformance. The notice will contain a detailed
description of the nature of the non-conformance. If no notice of
non-conformance is received by PEX before the end of the Initial Acceptance
Period, the Deliverables and overall paper procurement process shall be deemed
to be accepted. If Noosh rejects a Deliverable or the procurement process as a
whole as non-conforming, PEX shall have thirty (30) days following receipt of
Noosh's notice to correct the nom-conformance and deliver a modified Deliverable
for further testing. Noosh shall then have ten (10) days following delivery of
the modified Deliverable to determine whether it conforms to the applicable
acceptance criteria (the "Extended Acceptance Period"). If no notice of
non-conformance is received by PEX before the end of the Extended Acceptance
Period, the modified Deliverable shall be deemed to be accepted by Noosh. If
Noosh rejects the modified Deliverable, Noosh, in its option, shall have the
following sole and exclusive remedies: (i) to require the parties to continue
resubmitting modified Deliverables until they meet the acceptance criteria; or
(ii) to waive the unsatisfied acceptance criteria; provided that if Noosh does
not accept the resubmitted Deliverables within six (6) months from initial
submission, either party may terminate this Agreement with no liability to the
other party.

      2.5 Delays. The parties agree that any delay by one party in performing
the tasks which are identified as its responsibility in the Development Schedule
and which are a prerequisite for the performance of the other party shall extend
the non-delaying party's milestone dates for its performance on a day-for-day
basis (or longer, if the nature of the delay precludes the timely performance of
long lead time items or other obligations whose deferral causes more than a
day-for-day schedule slip).

      2.6 Collaboration on Initial Users. PEX and Noosh will cooperate to select
at least two customers -- one print buyer and one print supplier -- to use the
integration of the Noosh Service and the PEX Service and to provide feedback to
Noosh regarding such use ("Feedback"). Both parties will support the sales
effort for these customers with coordinated direct sales and training
interaction. Both PEX and Noosh agree that either party may use the ideas
generated from the Feedback in either party's future product development
(including but not limited to improvement of the PEX Service or Noosh Service.)
All such customers shall execute both PEX's and Noosh's standard user agreement
prior to use of the Noosh Service.

      2.7 Noosh API. PEX will use reasonable commercial efforts to assist Noosh
in developing its respective product descriptions and data types and protocols
for paper products according to the Noosh API for the elements of the business
processes required to integrate the

                                       6
<PAGE>

Noosh Service and the PEX Service. In addition, as reasonably requested by
Noosh, PEX will use reasonable commercial efforts to cooperate with Noosh to
integrate with Noosh's other paper suppliers according to the Noosh API.

      2.8 Data Normalization. The parties shall use reasonable commercial
efforts to work together in good faith to achieve acceptable levels of
authentication and security in such data transfers and to fairly apportion costs
of doing so. To the extent that a party provides the other party with direct
server access, the accessing party shall not disclose the applicable password to
third parties. The parties will use reasonable commercial efforts to cooperate
to further integrate the Noosh Service with the PEX Service as mutually agreed
(such integration may contain for example pre-populated registration for End
Users or other data transfer mechanisms). Noosh acknowledges that an End User
will be required to register and become a member of PEX to obtain the PEX
Service and agrees that it will facilitate the process for its members to
become PEX members.

      2.9 Disaster Recovery Plans. Each party will use reasonable commercial
efforts to implement disaster recovery and backup plans intended to minimize the
occurrence and impact of any disruption or downtime of each party's applications
on the other party's business.

      2.10 Look and Feel. Noosh shall determine the appearance and look and feel
of the Noosh Service and may change the Noosh Service from time to time.

      2.11 Accounts and Passwords.

            2.11.1 PEX will receive an account id, username and password to gain
access to and use the Noosh Service. PEX is responsible for maintaining the
confidentiality of its username and password, and is fully responsible for all
activities that occur under its username or account. PEX agrees (a) not to allow
a third party to use its account, username or password at any time and (b) to
notify immediately Noosh customer support of any actual or suspected
unauthorized use of its account, username or password, or any other breach or
suspected breach of security at 1-888-AT-NOOSH (1-888-286-6674) or at
support@noosh.com. Noosh cannot and will not be liable for any loss or damage
arising from unauthorized use of PEX's account, username or password.

            2.11.2 Noosh will receive an account id, username and password to
gain access to and use the PEX Service. Noosh is responsible for maintaining the
confidentiality of its username and password, and is fully responsible for all
activities that occur under its username or account. Noosh agrees (a) not to
allow a third party to use its account, username or password at any time and (b)
to notify immediately PEX customer support of any actual or suspected
unauthorized use of its account, username or password, or any other breach or
suspected breach of security. PEX cannot and will not be liable for any loss or
damage arising from unauthorized use of Noosh's account, username or password.
