Online Transactions which occur after the Effective Date hereof as more
particularly described below.  For purposes of this Exhibit A, "Online
                                                    ---------   ------
Transactions" shall refer to purchases of products by Members from Tenet
------------
Suppliers via the NewCo Marketplace, and "Non-Online Transactions" shall refer
                                          -----------------------
to all other purchases of products by Members from Tenet Suppliers.

     1.   Duties of NewCo.  NewCo agrees to conduct, supervise and effectively
manage the  day-to-day Non-Online Transaction business affairs of the Tenet GPO
as reasonably requested by Tenet during the term of this Agreement, including
the provision of all personnel reasonably required to accomplish this
undertaking.  Any powers not specifically delegated or granted by Tenet to NewCo
will remain with Tenet.  NewCo shall use all reasonable commercial efforts to
implement the Tenet GPO's policies and directives with the goal of causing the
Tenet GPO to provide quality group purchasing organization services to Members
consistent with the policies and directives set by Tenet, the financial
resources available to the Tenet GPO, the competitive marketplace in which the
Tenet GPO operates, Medicare reimbursement and other laws and, ultimately
migrate Non-Online Transactions to Online Transactions.  In the absence of such
oral or written policies or standards, NewCo shall be expected to exercise its
reasonable judgment in its management activities and to conduct such management
activities according to the same standards by which it governs its own affairs.
A description of certain of the management services to be provided by NewCo are
set forth on Attachment A hereto.  Without limiting the generality of the
             ------------
services described herein, such management services shall include personnel
administration, maintenance of accounting and financial, as required, payment of
accounts, including administrative fees, on behalf of the Tenet GPO to Members,
depositing funds in accounts designated by Tenet, preparation of an annual
business plan for the Tenet GPO including a Tenet GPO budget, marketing

1999 (the "Commencement Date") and unless sooner terminated as provided herein,
           -----------------
shall continue for as long as the Tenet GPO shall operate as a group purchasing
organization conducting Non-Online Transactions or until such time as Tenet,
upon 180 days prior notice to NewCo, because of a general reduction in Non-
Online Transactions, no longer requires such management services.

     3.   Retention of Authority.  Throughout the term of the provision of the
management services described herein, Tenet shall retain all authority and shall
exercise control over the business, policies, operation, and assets of the Tenet

with the reasonable policies and directives of Tenet as may be from time to time
provided to it, including approval of vendor and distributor agreements.  By

powers, duties, and responsibilities vested in Tenet by the bylaws of Tenet.  In
matters pertaining to the Tenet GPO, NewCo may rely on, assume the

this agreement, NewCo does not guarantee any particular results.  NewCo shall

quality services.

     5.   Management Fee and Expenses.  In exchange for NewCo's services
rendered to Tenet under the terms of this Exhibit A, Tenet shall pay NewCo the

and continuing on or before the tenth (10th) day of each calendar month
thereafter until the month following the expiration or earlier termination of
this agreement, NewCo shall provide Tenet with an itemization of Costs
attributed to the provision of management services described herein. Within

reasonably necessary for the operation of the Tenet GPO.

     9.   Annual Budget.  Within ninety (90) days of the end of each calendar
year, NewCo shall prepare and submit to Tenet a budget for providing the
management services described herein for the coming year.  Tenet shall have
forty-five (45) days from its receipt of the proposed budget to approve or
disapprove such proposed budget.  If Tenet accepts the budget, it will
constitute the budget for management fees and expenses for the coming year.  If
Tenet rejects the proposed budget, the parties will meet, as soon as is
reasonably practicable, and make a good faith attempt to resolve the disputed
items in the budget.  In the event the parties are unable to resolve the
disputed items, the parties will utilize the budget for the preceding year as
the budget for the coming calendar year.  For the first

                                      -2-

are commercially reasonable and agreed to by the parties naming Tenet as an

delay in exercising any right hereunder will operate as a waiver thereof, nor
will any single or partial exercise thereof preclude any other or further
exercise thereof or the exercise of any other right.

          3.  Chemdex Responsibilities.
              ------------------------

          (a) Delivery.  Chemdex and Promedix shall transfer the Licensed

parties and set forth on Exhibit D hereto.  All Upgrades and Updates shall be
                         ---------

terms and conditions similar to those enjoyed by Chemdex pursuant to its
agreements with such third parties.

          (i) Exclusions.  Notwithstanding the foregoing, Chemdex will have no

     4.   Promedix Responsibilities.
          -------------------------

          (a) Access to Promedix Commerce Site.  Promedix shall provide NewCo

NewCo Marketplace and purchases a product on the Promedix Commercial Site
("Transaction Fee").
  ---------------

          (c) Within thirty (30) days after the end of each calendar month,
Promedix will pay NewCo all Transaction Fees and Data Fees which accrued during

month (or, if less, the maximum allowed by applicable law).

     5.   NewCo Responsibilities.
          ----------------------

          (a) Fees.  NewCo will pay all Costs which Chemdex incurs in providing
              ----

services which Chemdex provides to NewCo pursuant to Section 9(e) shall be
provided free of charge.

          (b) Payment Terms.  All payments shall be made by NewCo within thirty
              -------------

              -----------
of Promedix Products through the NewCo Marketplace.  NewCo shall not make
Promedix Products of any third party supplier available for sale through the
NewCo Marketplace without the prior written consent of Promedix. NewCo shall not
collaborate with, work with, or assist, directly or indirectly in any way, any
third party supplier of Promedix Products, and shall not assist, directly or
indirectly, or in any way induce, any third party to compete with Promedix.
Notwithstanding the foregoing, NewCo shall have the right to make the products
of a third party supplier available for sale through the NewCo Marketplace if
such products are Routine Products, or if such products fall under the
definition of both Promedix Products and Routine Products.

     6.   Proprietary Rights.  Subject to the licenses granted to NewCo in
          ------------------

Licensed Technology, including, without limitation, all Intellectual Property
Rights therein.  Subject to the preceding sentence, NewCo shall own all right,
title and interest in and to modifications to the Licensed Technology made by
NewCo or its agents (other than Promedix or Chemdex).

     7.   Confidentiality.
          ---------------

          (a) Nondisclosure.  Each party shall treat as confidential all
              -------------
Confidential Information of the other parties, shall not use such Confidential
Information except as set forth herein, and shall use reasonable efforts not to
disclose such Confidential Information to any third party.  Without limiting the
foregoing, each of the parties shall use at least the same degree of care which
it uses to prevent the disclosure of its own confidential information of like
importance to prevent the disclosure of Confidential Information disclosed to it
by the other parties under this Agreement.  Each party shall promptly notify the
applicable party of any actual or suspected misuse or unauthorized disclosure of
such other party's Confidential Information.

          (b) Exceptions.  Notwithstanding the above, no party shall have
              ----------
liability to the other with regard to any Confidential Information of the other
which the receiving party can prove: (i) was in the public domain at the time it
was disclosed or has entered the public domain through no fault of the receiving
party; (ii) was known to the receiving party, without restriction, at the time
of disclosure, as demonstrated by files in existence at the time of disclosure;
(iii) is disclosed with the prior written approval of the disclosing party; (iv)
was independently developed by the receiving party without any use of the
Confidential Information, as demonstrated by files created at the time of such
independent development; (v) becomes known to the receiving party, without
restriction, from a source other than the disclosing party without breach of
this Agreement by the receiving party and otherwise not in violation of the
disclosing party's rights; or (vi) is disclosed pursuant to the order or
requirement of a court, administrative agency, or other governmental body;
provided, however, that the receiving party shall provide prompt notice thereof
to the disclosing party to enable the disclosing party to seek a protective
order or otherwise prevent or restrict such disclosure.

          (c) Return of Confidential Information.  Upon expiration or
              ----------------------------------
termination of this Agreement, upon the request of the disclosing party, and
subject to Section 10(c), each party shall return or destroy all Confidential
Information received from the other parties.

          (d) Remedies.  Any breach of the restrictions contained in this
              --------
Section 7 is a breach of this Agreement which may cause irreparable harm to the
nonbreaching party.  Any such breach shall entitle the nonbreaching party to
injunctive relief in addition to all legal remedies.

                                      -6-
<PAGE>

          (e) Confidentiality of Agreement.  Each party shall be entitled to
              ----------------------------
disclose the existence of this Agreement, but agrees that the terms and
conditions of this Agreement shall be treated as Confidential Information and
shall not be disclosed to any third party; provided, however, that each party
may disclose the terms and conditions of this Agreement: (i) as required by any
court or other governmental body; (ii) as otherwise required by law; (iii) to
legal counsel of the parties; (iv) in confidence, to accountants, banks, and
financing sources and their advisors; (v) in connection with the enforcement of
this Agreement or rights under this Agreement; (vi) in confidence, in connection
with an actual or proposed merger, acquisition, or similar transaction; or (vii)
as mutually agreed upon by the parties.

     8.   Indemnification.
          ---------------

          (a) Indemnification by Chemdex and Promedix.  Chemdex and Promedix
              ---------------------------------------
jointly and severally agree, at their own expense, to defend or at their option
to settle any claim or action brought against NewCo on the issue of infringement
of any United States Intellectual Property Right by the Licensed Technology as
delivered to NewCo under this Agreement, and to indemnify NewCo against any and
all damages, liabilities, and costs, including legal fees, incurred by NewCo as
a result of any such claim or action; provided that NewCo provides Chemdex and
                                      --------
Promedix with (i) prompt written notice of such claim or action (provided,
however, that the failure of NewCo to give prompt notice to Chemdex and Promedix
shall not relieve Chemdex and Promedix of their obligations hereunder unless,
and then only to the extent that, the failure to give prompt notice adversely
affects Chemdex's or Promedix's ability to defend the claim, or increases the
damages for which Chemdex or Promedix is liable hereunder), (ii) sole control
and authority over the defense or settlement of such claim or action (provided
that NewCo shall have the right to participate, at its own expense, and with
counsel of its choice, in such defense or settlement) and (iii) proper and full
information and reasonable assistance (at the expense of Chemdex and Promedix)
to defend and/or settle any such claim or action.  Chemdex and Promedix shall
have no liability if the alleged infringement is caused by (a) any combination
of the Licensed Technology with equipment, programs or data not authorized by
Chemdex or Promedix for use with the Licensed Technology, where such Licensed
Technology alone would not have given rise to the claim, (b) use of the Licensed
Technology by NewCo or any other party other than as authorized under Section 2,
or (c) changes to the Licensed Technology made by NewCo or its agents, other
than Promedix or Chemdex, to the extent such claim would not have arisen but for
such modification.  Notwithstanding the foregoing, Chemdex and Promedix shall
not enter into any settlement or consent to any adverse judgment that would
adversely affect the rights, interest, or business of NewCo without the prior
written consent of NewCo.

          (b) Injunctions.  In the event that the Licensed Technology is, or in
              -----------
Chemdex's or Promedix's sole opinion is likely to be, enjoined due to the type
of infringement described in Section 8(a), Chemdex or Promedix, at its option
and expense, may either (i) modify the Licensed Technology so that it becomes
non-infringing but functionally equivalent, (ii) replace the Licensed Technology
with functionally equivalent non-infringing products reasonably acceptable to
NewCo, or (iii) obtain a license with respect to the applicable third party
Intellectual Property Rights.

          (c) Limitation.  THE FOREGOING PROVISIONS OF THIS SECTION 8 STATE THE
              ----------
ENTIRE LIABILITY AND OBLIGATIONS OF CHEMDEX AND PROMEDIX HEREUNDER AND THE
EXCLUSIVE REMEDY OF NEWCO, WITH RESPECT TO ANY ALLEGED OR ACTUAL INFRINGEMENT OF
PATENTS, COPYRIGHTS, TRADE SECRETS, TRADEMARKS OR OTHER INTELLECTUAL PROPERTY
RIGHTS BY THE LICENSED TECHNOLOGY.

                                      -7-
<PAGE>

          (d) Indemnification by NewCo.  NewCo agrees to indemnify and hold
              ------------------------
Chemdex and Promedix harmless against any damages, costs (including attorneys'
fees and costs) or other liability arising from claims by any other party
resulting from (i) NewCo's use of the Licensed Technology or components thereof,
except as authorized under Section 2, or (ii) any modifications to the Licensed
Technology made by NewCo; provided that Chemdex and Promedix provide NewCo with
                          --------
(A) prompt written notice of such claim or action, (B) sole control and
authority over the defense or settlement of such claim or action and (C) proper
and full information and reasonable assistance to defend and/or settle any such
claim or action.

     9.   Representations, Warranties and Covenants.  Chemdex and Promedix
          -----------------------------------------
jointly and severally represent, warrant and covenant to NewCo as follows:

          (a) Ownership.  Chemdex and Promedix have full title and ownership of,
              ---------
or have license to, the Licensed Technology and Licensed Intellectual Property
Rights. Chemdex and Promedix have taken, and in the future Chemdex and Promedix
will use their commercially reasonable efforts to take, all steps reasonably
necessary to preserve their legal rights in, and the secrecy of, all Licensed
Technology and Licensed Intellectual Property Rights, except those for which
disclosure is required for legitimate business or legal reasons.  Neither
Chemdex nor Promedix believes it is or will be necessary to utilize any
inventions of any Chemdex or Promedix employees (or persons Chemdex or Promedix
currently intends to hire) made prior to their employment by Chemdex or
Promedix.  To the best knowledge of Chemdex and Promedix, at no time during the
conception of or reduction of any of the Licensed Technology or Licensed
Intellectual Property Rights to practice was any developer, inventor or other
contributor to such patents operating under any grants from any governmental
entity or agency or private source, performing research sponsored by any
governmental entity or agency or private source or subject to any employment
agreement or invention assignment or nondisclosure agreement or other obligation
with any third party that could adversely affect Chemdex's or Promedix's rights
in such Licensed Technology or Licensed Intellectual Property Rights.

          (b) Warranty of Software.  The Software, and each Upgrade and Update
              --------------------
thereto, will conform in all respects to the Specifications for a period of
thirty (30) days after the delivery of such Software (or Upgrade or Update
thereto) to NewCo.  The Software, including without limitation all documentation
included in the Software, shall be in sufficient detail to enable a competent
engineer to promptly address any issues with the Licensed Technology that may
arise.

          (c) Y2K Compliance Statement. (i) the Software will operate, perform
              ------------------------
and function normally, including without limitation, performing normal
processing, sequencing, transmission, storage, calculation or manipulation of
data, without interruption or abnormal human intervention, regardless of the
current date, (ii) all date-based or date-dependent functionality of the
Software will behave consistently for dates before, at and after January 1,
2000, (iii) in all interfaces or data storage, the Software will correctly
identify or specify the correct century in any date either explicitly or by
unambiguous algorithms or interfacing rules, (d) to the extent the Software
encounters data which cannot be readily identified as to the correct century,
the Software will not cause an abnormal ending scenario for itself or another
application, and will segregate and capture such non-compliant data such that it
can be processed or reviewed by an alternative means, and (e) year 2000 will be
recognized as a leap year.

          (d) Sufficiency.  The Licensed Technology, Licensed Intellectual
              -----------
Property Rights, and Third Party Technology are sufficient to allow NewCo to
operate the NewCo Marketplace in accordance with Exhibit G.  To the extent that
                                                 ---------
Licensed Technology, Licensed Intellectual Property Rights, and Third Party
Technology are not sufficient to allow NewCo to operate the NewCo Marketplace in
accordance with Exhibit G as NewCo's exclusive remedy, Chemdex shall use
                ---------

                                      -8-
<PAGE>

commercially reasonable efforts to obtain for NewCo all technology and
Intellectual Property Rights necessary for NewCo to operate the NewCo
Marketplace in accordance with Exhibit G.
                               ---------

          (e) Remedy.  As NewCo's sole remedy and Chemdex's and Promedix's
              ------
exclusive liability for any breach by Chemdex or Promedix of the warranties set
forth in Sections 9(b) and 9(c), Chemdex or Promedix will promptly remedy any
failure of the Software to conform with such warranties.  Chemdex and Promedix
will have no liability under this Section for any failure of the Software to
comply with the warranty set forth under Section 9(b) or 9(c) due to (a) the
combination of the Software with hardware or software not authorized by Chemdex
or Promedix for use with the Software, (b) changes to the Software not made or
authorized by Chemdex or Promedix, or (c) network connectivity problems,
including, without limitation, problems connecting to the Internet or problems
relating to Internet service providers.

          (f) EXCEPT AS SET FORTH IN THIS SECTION 9, CHEMDEX AND PROMEDIX
PROVIDE THE PRODUCTS, THE SERVICES, AND THE CHEMDEX SYSTEM "AS IS", AND NEWCO
RECEIVES NO WARRANTIES IN CONNECTION WITH THE LICENSED TECHNOLOGY, WHETHER
EXPRESS, IMPLIED, CONTRACTUAL OR STATUTORY, AND CHEMDEX SPECIFICALLY DISCLAIMS
ANY IMPLIED WARRANTY OF MERCHANTABILITY, NONINFRINGEMENT  OR FITNESS FOR A
PARTICULAR PURPOSE.

          (g) The parties hereto covenant that they will work together in good
faith to present customers and potential customers with a single technology
solution for the purchase of healthcare products.

     10.  Term and Termination.
          --------------------

          (a) Term.  Subject to Section 10(c), this Agreement shall be effective
              ----
from the Effective Date and shall continue in effect for a period of fifteen
(15) years unless terminated earlier pursuant to the provisions of Section
10(b).

          (b) Termination for Cause.  If any party materially defaults in the
              ---------------------
performance of any provision of this Agreement, and if the non-defaulting party
wishes to terminate this Agreement due to such default, then the non-defaulting
party shall give written notice to the defaulting party that if the default is
not cured within sixty (60) days the Agreement will be terminated.  If the non-
defaulting party gives such notice and the default is not cured during the sixty
(60) day period, then the non-defaulting party will have the right to terminate
this Agreement upon written notice to the other parties at the end of such
period; provided, however, that if such default is a material breach by NewCo of
the restrictions set forth in Section 2(c), then such cure period shall be
reduced to thirty (30) days.  Notwithstanding the foregoing provisions of this
Section 10(b), (i) Chemdex and Promedix shall have the right to terminate this
Agreement in accordance with this Section 10(b) only if NewCo materially
breaches the provisions of Section 2(c), and (ii) Tenet shall not have the right
to terminate this Agreement.

          (c) Effect of Termination. The provisions of Sections 1, 2(a), 2(c),
              ---------------------
5(c), 6, 8, 9 (except for 9(g)), 10(c), 11, and 12 of this Agreement, and all
payment obligations incurred under Section 5 during and after the term of this
Agreement, shall survive the termination of this Agreement for any reason;
provided, however, that Section 2(a) shall not survive the termination of this
Agreement if Chemdex or Promedix terminates this Agreement for cause pursuant to
the last sentence of Section 10(b).  The provisions of Section 7 of this
Agreement shall survive the termination of this Agreement for a period of three
(3) years.  All other rights and obligations of the parties shall cease upon
termination of this Agreement.  Upon the termination of this Agreement, NewCo
shall return or destroy the Licensed Technology, and all copies of software and
documentation related thereto.

                                      -9-
<PAGE>

     11.  Limitation of Liability. IN NO EVENT SHALL CHEMDEX'S AND PROMEDIX'S
          -----------------------
AGGREGATE LIABILITY ARISING UNDER THIS AGREEMENT EXCEED TEN MILLION DOLLARS.
EXCEPT AS EXPLICITLY SET FORTH IN SECTION 8 OR 9(d), IN NO EVENT SHALL ANY PARTY
BE LIABLE TO THE OTHERS FOR COSTS OF PROCUREMENT OF SUBSTITUTE PRODUCTS OR
SERVICES, LOST PROFITS, OR ANY CONSEQUENTIAL, SPECIAL, PUNITIVE, INCIDENTAL, OR
INDIRECT DAMAGES, HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY (INCLUDING
NEGLIGENCE OR STRICT LIABILITY), ARISING OUT OF THIS AGREEMENT.  NEWCO
ACKNOWLEDGES AND AGREES THAT THE AMOUNTS PAYABLE HEREUNDER BY NEWCO ARE BASED IN
PART UPON THESE LIMITATIONS, AND FURTHER AGREES THAT THESE LIMITATIONS SHALL

merger partner, successor in business or acquirer of all or substantially all of
such party's business or assets without obtaining consent from the other parties
to such assignment.  The terms and conditions of this Agreement shall inure to
the benefit of and be binding upon the respective permitted successors and

              ------------
held to be unenforceable under applicable law, the parties agree to renegotiate
such provision in good faith, in order to maintain the economic position enjoyed
by each party as close as possible to that under the provision rendered
unenforceable.  In the event that the parties cannot reach a mutually agreeable
and enforceable replacement for such provision, then (i) such provision shall be
excluded from this Agreement, (ii) the balance of the Agreement shall be
interpreted as if such provision were so excluded and (iii) the balance of the
Agreement shall be enforceable in accordance with its terms.

          (i) Independent Contractor.  No party shall, for any purpose, be
              ----------------------
deemed to be an agent of any other party and the relationship between the
parties shall only be that of independent contractors.  No party shall have any
right or authority to assume or create any obligations or to make any
representations or warranties on behalf of any other party, whether express or
implied, or to bind any other party in any respect whatsoever.

          (j) Force Majeure.  In the event that any party is prevented from
              -------------
performing or is unable to perform any of its obligations under this Agreement
(other than a payment obligation) due to any Act of God, fire, casualty, flood,
earthquake, war, strike, lockout, epidemic, destruction of production
facilities, riot, insurrection, material unavailability, or any other cause
beyond the reasonable control of the party invoking this Section, and if such
party shall have used its best efforts to mitigate its effects, such party shall
give prompt written notice to the other parties, its performance shall be
excused, and the time for the performance shall be extended for the period of
delay or inability to perform due to such occurrences.

          (k) Entire Agreement.  This Agreement (as amended pursuant to Section
              ----------------
12(a)) constitutes the entire agreement of the parties pertaining to the subject
matter hereof, and merges all prior negotiations and drafts of the parties with
regard to the transactions contemplated herein.  Any and all other written or
oral agreements existing between the parties hereto regarding such transactions
are expressly canceled.

                                      -11-

          (l) Advice of Legal Counsel.  Each party acknowledges and represents
              -----------------------
that, in executing this Agreement, it has had the opportunity to seek advice
regarding its legal rights from legal counsel and that the person signing on its
behalf has read and understood all of the terms and provisions of this
Agreement.  This Agreement shall not be construed against any party by reason of
the drafting or preparation thereof.

          (m) U.S. Government Restricted Rights.  The Licensed Technology is a
              ---------------------------------
"commercial item," as that term is defined at 48 C.F.R. 2.101 (Oct. 1995),
consisting of "commercial computer software" and "commercial computer software
documentation," as such terms are used in 48 C.F.R. 12.212 (Sept. 1995).
Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4
(June 1995), all U.S. Government users acquire only those rights in the Licensed
Technology that are provided in this Agreement.

          (n) Export Restrictions. NewCo, at its own expense, shall obtain all
              -------------------
import and export licenses and permits and pay all custom charges and duty fees,
if any, and shall take all other actions, if any, required to accomplish any
export and import of the Licensed Technology by NewCo in accordance with
applicable laws and regulations. NewCo acknowledges that any obligation by
Chemdex to provide the Licensed Technology under this Agreement shall be subject
in all respects to all United States laws and regulations governing the license
and delivery of technology and products abroad by persons subject to the
jurisdiction of the United States. NewCo shall not export or re-export, directly
or indirectly, the Licensed Technology or related information without first
obtaining all required licenses and approvals from the appropriate government
agencies.

          (o) Audits. Each party will maintain accurate records with respect to
              ------
payments due under this Agreement and methodology used to calculate payment due.
Each party may, upon no less than thirty (30) days prior written notice to
another party which owes such party payments hereunder, cause an independent
Certified Public Accountant to inspect all relevant records of such other party
upon which the calculation of such payments are based during normal business
hours and without disruption to such other party's business.  The fees charged
by such Certified Public Accountant in connection with the inspection will be
paid by the auditing party unless the payments made to the auditing party are
determined to have been less than ninety percent (90%) of the payments actually
owed to the auditing party, in which case the other party will be responsible
for the payment of the reasonable fees for such inspection. In addition, the
other party shall immediately remit payment to the auditing party for the full
amount of any disclosed shortfalls.  The audit rights set forth herein shall
continue for one (1) year following the termination of this Agreement for any
reason. No such audit may occur more than once a year during the term of this
Agreement.

          (p) Expenses.  Each of the parties hereto shall bear its own expenses
              --------
(including without limitation attorneys fees) in connection with the negotiation
and consummation of this Agreement.

          (q) No Third Party Beneficiaries.  Nothing expressed or implied in
              ----------------------------
this Agreement is intended, or shall be construed, to confer upon or to give any
person, firm or corporation, other than the parties hereto, any rights or
remedies under or by reason of this Agreement.

          (r) Attorneys' Fees.  Should a suit or arbitration be brought to
              ---------------
enforce or interpret any provision of this Agreement, the prevailing party shall
be entitled to recover reasonable attorneys' fees and costs (including
reasonable fees and costs allocable to services provided by the prevailing
party's in-house counsel) to be fixed in amount by the court or the
arbitrator(s) (including without limitation costs, expenses and fees on any
appeal).

                                      -12-
<PAGE>

          (s) Dispute Resolution.  The parties agree to negotiate in good faith
              ------------------
to resolve any dispute between them regarding this Agreement.  If the
negotiations do not resolve the dispute to the reasonable satisfaction of the
parties, then each party shall nominate one senior officer of the rank of Vice
President or higher as its representative. These representatives shall, within
thirty (30) days of a written request by either party to call such a meeting,
meet in person and alone (except for one assistant for each party) and shall
attempt in good faith to resolve the dispute. If the disputes cannot be resolved
by such senior managers in such meeting, the parties agree that they shall, if
requested in writing by either party, meet within thirty (30) days after such
written notification for one day with an impartial mediator and consider dispute
resolution alternatives other than litigation.  If an alternative method of
dispute resolution is not agreed upon within thirty (30) days after the one day
mediation, either party may begin litigation proceedings. This procedure shall
be a prerequisite before taking any additional action hereunder.

                                   EXHIBIT C

                  SECURE PROCEDURES FOR HANDLING SOURCE CODE

1.   AUTHORIZED EMPLOYEES AND CONTRACTORS. NewCo agrees that it will not
     disclose all or any portion of the Source Code to third parties, with the
     exception of authorized employees ("Authorized Employees") and authorized
                                         --------------------
     contractors ("Authorized Contractors") who (a) require access thereto for a
                   ----------------------
     purpose expressly authorized by this Agreement and (b) have signed an
     employee or contractor agreement in which such employee or contractor
     agrees to protect third party confidential information.  NewCo guarantees
     the compliance of all such Authorized Employees and Authorized Contractors
     with their obligations under such confidentiality agreements.

2.   SOURCE CODE.

     2.1  NewCo shall use its best efforts to ensure that all Source Code, and
          copies made thereof, will be appropriately identified as source code
          proprietary to Chemdex, Promedix, and their licensors before being
          made available to Authorized Employees and Authorized Contractors
          hereunder.

     2.2  NewCo shall ensure that, at a minimum, the same degree of care is used
          to prevent the unauthorized use, dissemination, or publication of the
          Source Code as NewCo uses to protect its own confidential information
          of a like nature, but in no event shall the safeguards for protecting
          such Source Code be less than a reasonably prudent business would
          exercise under similar circumstances. NewCo shall take prompt and
          appropriate action to prevent unauthorized use or disclosure of Source
          Code.

     2.3  NewCo shall instruct Authorized Employees and Authorized Contractors
          not to disclose Source Code to anyone not authorized to receive it and
          will use its best efforts to ensure that all Authorized Employees and
          Contractors comply with such instruction.

     2.4  NewCo shall instruct Authorized Employees and Authorized Contractors
          not to copy Source Code except for loading onto a reasonable number of
          computers to be used solely by such Authorized Employees and
          Authorized Contractors. Any such copies of Source Code shall be
          properly marked or otherwise appropriately identified as source code
          proprietary to Chemdex, Promedix, and their licensors.

     2.5  Source Code shall be handled, used, and stored solely at NewCo's
          facility.

3.   TRADE SECRETS. Source Code, including the techniques, algorithms, and
     processes contained in the Source Code which have been developed, acquired,
     or licensed by Chemdex or Promedix, or any modification or extraction
     thereof, constitute trade secrets of Chemdex, Promedix, and/or their
     suppliers, and will be used by NewCo only in accordance with the terms of
     this Agreement.  NewCo will take all measures required to protect the
     proprietary rights of Chemdex, Promedix, and their suppliers in the Source
     Code and will promptly notify Chemdex and Promedix of any lost or missing
     items and take all reasonable steps to recover such items.

4.   CERTIFICATION. At Chemdex's or Promedix's request, but no more than once in
     any twelve (12) month period, NewCo will provide Chemdex and Promedix with
     written certification by an officer of NewCo of NewCo's compliance with its
     obligations under Paragraph 1 ("Authorized Employees and Contractors") of
                                     ------------------------------------
     this Exhibit.

* Confidential Treatment Requested. Bolded and Bracketed portions have been
omitted and have been separately filed with the SEC.
<PAGE>

5.   AUDIT. During the term of this Agreement and for a period of eighteen (18)
     months thereafter, an independent auditor selected by Chemdex or Promedix
     shall have access to such portion of NewCo's records and premises to allow
     Chemdex to determine whether NewCo is substantially in compliance with this
     Exhibit.  In no event shall audits be made hereunder more frequently than
     once per year.  Such access shall be (a) during NewCo's regular business
     hours, (b) arranged so that, to the extent possible, NewCo's regular
     business activities are minimally disrupted and (c) under the terms of an
     appropriate confidentiality agreement executed by the individual(s)
     conducting such audit.  If Chemdex or Promedix determines, after conducting
     such audit, that NewCo is not substantially in compliance with its
     obligations to protect Chemdex's and Promedix's proprietary rights, NewCo
     shall pay the costs of such audit.  Otherwise, Chemdex and Promedix shall
     pay the costs of such audit.  Such payment will not preclude Chemdex and
     Promedix from exercising any right which it may have under the Agreement.
     NewCo shall immediately correct any deficiencies discovered in the course
     of the audit.

the Licensed Technology, eliminates the material adverse effect of such Error on
NewCo.

     "First Level Support" means support which NewCo will provide directly to
      -------------------
its customers and end users, including, without limitation, answering customer
and end user questions, resolving technical difficulties related to the NewCo
