court of competent jurisdiction  an injunction or other equitable relief,
without the necessity of actual monetary loss being proved and without the
necessity of posting a bond, in order that a breach or threatened breach of this
Section may be effectively enjoined.  Equitable relief shall not be deemed to be
the exclusive remedy for any breach of any provision of this Section but shall
be in addition to all other remedies provided by law or equity.  No failure or
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.

          (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.

          (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.

     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

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

          (h) Severability.  If one or more provisions of this Agreement are
              ------------
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

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

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.

          (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 following terms and conditions shall apply to Second Level Support services
provided by Chemdex to NewCo for the Licensed Technology. The parties will agree
and document the escalation process by which technical problems will be
escalated from First Level Support to Second Level Support.

1.   Definitions. For purposes of this Exhibit, the following terms shall have
     -----------
the following meanings. Any terms not defined in this Exhibit shall have the
meaning set forth in the Agreement.

     "Error(s)" means any verifiable and reproducible failure of the Licensed
      -------
Technology to materially conform to the Specifications.  The term "Error" shall
not include any failure of the Licensed Technology that: (a) results from the
misuse or improper use of the Licensed Technology; (b) does not materially
affect the operation and use of the Licensed Technology; (c) results from any
modification to the Licensed Technology not made by Chemdex; or (d) results from
the failure to incorporate or use any Updates, Upgrades or bug fixes made
available to NewCo by Chemdex.

     "Error Correction(s)" means either (a) a modification or addition to or
      -------------------
deletion from the Licensed Technology that, when made to such Licensed
Technology, materially conforms the Licensed Technology to the Specifications,
or (b) a procedure or routine that, when observed in the regular operation of
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
Marketplace which NewCo is capable of resolving without the assistance of
Chemdex, providing on-site technical support to customers, and generally
assisting customers and end users in the use of the NewCo Marketplace.

     "Major Error" means any demonstrable Error in the Licensed Technology
      -----------
that:  (a) causes the Licensed Technology to have a significant loss of intended
function as set forth in the Specifications; (b) causes or is likely to cause
data to be lost or destroyed; or (c) prevents the Licensed Technology from being
installed or operated in the properly configured environment.

     "Moderate Error" means any demonstrable Error in the Licensed Technology
      --------------
that: (a) causes the Licensed Technology to operate improperly; or (b) produces
results materially different from those described in the Specifications, but
which error does not rise to the level of a Major Error.

     "Minor Error" means any demonstrable Error that: (a) causes a function to
      -----------
not execute as set forth in the Specifications, without a significant loss of
intended functionality; or (b) disables one or more nonessential functions.

     "Second Level Support" means support which Chemdex will provide to NewCo's
      --------------------
authorized First Level Support personnel to identify and resolve Errors.

     "Workaround" means that Chemdex has diagnosed the Error and has
      ----------
implemented, or enabled NewCo to implement, a temporary solution that allows the
Licensed Technology to regain functionality and provide all major functions in
accordance with the Specifications.

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