(as appropriate) shall apply as written. All termination provisions set forth in
Section 13.5 of this Agreement shall apply to any Designated Location terminated
according to this Section 5.13. Should Subscriber terminate a Designated

Licensed Program as provided in Section 2, NetGenics shall provide two (2) days
of on-site end-user training to Subscriber at a Designated Location at no
additional charge to Subscriber. Additional training beyond the initial two (2)
days of training described above shall be deducted from the Service Hours as set
forth in EXHIBIT G, or, if Subscriber has utilized all Service Hours for that
calendar quarter, shall be charged to Subscriber at NetGenics' standard billing
rates then in effect.

         (e) As a part of the installation, NetGenics shall install one Object
Request Broker (ORB) on one computational server at Subscriber's Designated
Location at no cost to Subscriber's Service Hours.

     6.2 Subscriber is entitled to receive from NetGenics the number of Service
Hours per calendar year as set forth in EXHIBIT C. This Section 6.2 and EXHIBIT
G attached hereto sets forth the manner in which Service Hours may be used by
Subscriber. Any unused Service Hours at the end of a calendar year shall be
forfeited and canceled.

         (a) Upon receipt of reasonable advance notice from Subscriber,
NetGenics shall use commercially reasonable efforts to provide Subscriber with
on-site support Services, and the number of Service Hours shall be deducted from
the Service Hours available to Subscriber in exchange for such on-site Services,
as provided in EXHIBIT G attached hereto.

         (b) Subscriber shall request Services (including, but not limited to,
development of custom software modules) from NetGenics by completing the form
attached hereto as EXHIBIT D, detailing the Services requested. NetGenics shall
determine the amount and type of Services required, and the schedule for such
Services and forward to Subscriber a response in the form of a statement of
Services, on EXHIBIT E attached hereto. After Subscriber's review and approval
in writing of the statement of Services covering a Services project, NetGenics
shall perform the Services. During a Services project, the number of Service
Hours set forth in the statement of Services shall be



                                       11
<PAGE>   12

deducted from those available to Subscriber under this Agreement. Payment for
Services provided by NetGenics on a Services project in excess of such available
Service Hours shall be based on the hourly rates of NetGenics in effect at the
time such Services are provided. Hourly rates for such Services are detailed on
EXHIBIT I, which may be changed, from time to time, upon written notice to
Subscriber. The number of Service Hours deemed to be used for any Service
request shall be the number specified in the statement of Services to Subscriber
prior to the commencement of such Services. Should such Services include the
design and development of custom software modules, such Services shall be
performed according to the procedure in Sections 7.1 and 7.2 of this Agreement.

         (c) In the event Subscriber requests that NetGenics provide on-site
monitoring in lieu of remote site support otherwise available under Section
6.1(b) of this Agreement, Subscriber shall be charged Service Hours each
calendar quarter for such on-site monitoring as set forth in EXHIBIT G.

         (d) Service Hours will be accounted for on a calendar quarter basis and
NetGenics shall provide Subscriber with monthly cumulative reports during each
calendar quarter detailing projects for which Service Hours were used and the
number of Service Hours used. Once Subscriber has exhausted its Service Hours
for any calendar year, Subscriber shall be charged for any such additional
Services at NetGenics' standard billing rates then in effect, in addition to all
out-of-pocket expenses incurred by NetGenics in connection therewith as
described in Section 10.2.

         (e) Except as provided in Section 10.2 and EXHIBIT G of this Agreement,
each party shall bear its own travel expenses related to the performance of this
Agreement.

         (f) NetGenics acknowledges that Subscriber may request Services which
relate to the integration of the Licensed Program with Third Party Software or
to creating interfaces between the Licensed Program and other CORBA-based
systems. NetGenics shall use best commercial efforts to deliver such Services to
Subscriber, pursuant to this Section 6.2 and Article 7 herein. Notwithstanding
the foregoing, any delivery of Services which involve any Third Party Software
or CORBA-based systems shall be dependent upon the cooperation and timely
disclosure of requested and necessary technical information from the owner(s) of
any such Third Party Software or CORBA-based systems and shall not require
NetGenics to disclose its Confidential Information to any third party which
NetGenics, in its sole estimation, deems to be competitive with its business.
Subscriber agrees to provide reasonable assistance to NetGenics in the
attainment of such cooperation and technical information as might be required by
NetGenics in conjunction with the delivery of such requested Services.

         (g) NetGenics shall be obligated to provide disaster recover/restore
Services to Subscriber, in the event a full system restore is needed. Unless
such restore



                                       12
<PAGE>   13

Services are directly caused by defects otherwise covered under Warranty,
Subscriber shall incur charges to Service Hours for such Services.


         6.3 NetGenics shall deliver Service Hours to Subscriber as
mutually-agreed in the System Committee; provided, however, that NetGenics shall
not be obligated to provide Service Hours during any one calendar quarter in
excess of one half (1/2) the total number of service hours allotted for one
calendar year.

         6.4 As soon as reasonably practicable after the Effective Date, the
parties shall form a committee comprised of no more than three (3)
representatives from each party (the "System Committee"). The System Committee
shall meet no less often than on a quarterly basis (with the venue alternating
between a Subscriber Designated Location and a NetGenics location, unless
otherwise mutually agreed) and shall be charged with the following duties: (a)
coordinating the installation of the Product and the training as provided in
Section 6.1(d) above, (b) overseeing Hardware upgrades and replacements, (c)
formulating, discussing and agreeing to Service requests, including the number
of Service Hours to be used in designing and delivering custom software and
whether any Subscriber Know-How exists in custom software requested by
Subscriber and issues relating to the acceptance of custom software and (d)
except as otherwise provided in Section 7.2 (b), resolving disputes between the
parties arising out of or in connection with this Agreement.

7. CUSTOMIZATION METHODOLOGY
   -------------------------

         7.1 (a) If Subscriber desires that the Licensed Program be modified,
customized or adapted in any respect to suit Subscriber's specific requirements
through the development of custom software modules, Subscriber shall deliver to
NetGenics written notice thereof, in the form of EXHIBIT D, specifying
Subscriber's requirements in as much detail as possible. Upon receipt of such
notice, NetGenics and Subscriber shall cooperate in good faith to agree upon the
scope of such Services, detailed requirements, high-level design, the timetable
for development and implementation and cost (or Service Hours) therefor;
provided, however, that nothing in this Agreement shall be deemed to (i)
obligate NetGenics to perform any Services in excess of those available by way
of Subscriber's then available Service Hours or (ii) provide Services related to
custom software modules deemed by NetGenics, in its sole discretion, to be
unfeasible. Such agreement shall be set forth in writing, referencing this
Agreement, and shall be incorporated herein as EXHIBIT E.

            (b) To the extent the number of Service Hours that NetGenics
estimates will be required to complete a custom software module, as specified in
the aforementioned, mutually agreed development schedule during a calendar year
exceeds Subscriber's then-unused Service Hours for such calendar year, such
customization Services shall be charged to Subscriber at NetGenics' standard
billing rates then in effect.



                                       13
<PAGE>   14

            (c) Subject to the limitations set forth in Section 14 hereto,
NetGenics warrants that a custom software module, once completed and accepted by
Subscriber in accordance with the terms hereof, shall perform in all material
respects in accordance with the established, mutually-agreed detailed
requirements specified on EXHIBIT E.

            (d) Subscriber and NetGenics acknowledge that a custom software
module may contain Subscriber Know-How. In the event Subscriber seeks to
designate part of a custom software module as Subscriber Know-How, Subscriber
shall inform NetGenics of same in writing as a part of EXHIBIT D, and NetGenics
and Subscriber shall jointly agree on the scope of such Subscriber Know-How, and
the extent to which such Subscriber Know-How (i) is necessary to the custom
software module, (ii) does not contain NetGenics Confidential Information, and
(iii) provides competitive advantage to Subscriber, and shall designate same on
EXHIBIT E. NetGenics shall not re-use or incorporate such Subscriber Know-How in
the design or development of any custom software module for any third-party
subscriber of the Software. Notwithstanding the foregoing, NetGenics shall not
be restricted in providing any custom software module to any third party
subscriber which (A) does not contain Subscriber Know-How, or (B) is designed by
NetGenics according to such third party's independent specifications. Service
Hours charged for such customer software modules may be adjusted to reflect lack
of re-use by NetGenics. The System Committee (defined in Section 6.4) shall
determine the scope of Subscriber Know-How and shall resolve any disputes
relating to Service Hours charged for Customer Software Modules.

     7.2 (a) NetGenics shall use commercially reasonable efforts to install
custom software modules in accordance with the schedule set forth in the
completed EXHIBIT E, subject to Subscriber performing its obligations under this
Agreement and providing such cooperation as NetGenics may reasonably request to
facilitate such installation. Such installation with respect to any custom
software module shall be deemed complete upon written notice from NetGenics to
Subscriber.

            (b) Subscriber shall be deemed to have accepted a custom software
module with respect to which any installation notice has been provided by
NetGenics unless (i) such installed custom software module materially fails to
conform to the specifications as set forth on EXHIBIT E therefor, (ii)
Subscriber gives notice of nonacceptance to NetGenics within thirty (30) days
after the date of such installation notice, and (iii) any such notice of
non-acceptance states specifically with respect to such installed custom
software module, the custom software specifications to which such installed
custom software module fails to conform with sufficient specificity to permit
NetGenics to correct such nonconformity. NetGenics shall use commercially
reasonable efforts to correct any nonconformity found to exist and notify
Subscriber in writing upon the completion of such correction. If NetGenics is
unable to make such corrections, Subscriber's remedy shall be limited, at
NetGenics' sole discretion, to correction of the nonconforming portion of the
custom software



                                       14
<PAGE>   15

module or return of the custom software module to NetGenics and the crediting of
expended Service Hours. Subscriber shall cooperate with NetGenics in correcting
such nonconformity.

         7.3 Prior to developing any module of Subscriber Software to be covered
by the warranty provisions of Section 14, Subscriber shall have: (a) received
from NetGenics a current copy of any applicable Subscriber Software development
guidelines as described and updated from time to time on the Documentation and
covering such module, (b) submitted a proposal to NetGenics for approval
describing the methodology, specifications and timetable of such Subscriber
Software module, and (c) received NetGenics' written approval for the
development of such Subscriber Software. Subscriber hereby agrees to develop
Subscriber Software modules only in conjunction with a Development System, and
in accordance with the Subscriber Software development guidelines covering such
module. Upon completion of Subscriber Software, Subscriber shall submit
completed Subscriber Software to NetGenics for quality assurance testing, and
shall not install any such Subscriber Software on the Product until NetGenics
has completed such quality assurance testing and provided final approval to
Subscriber. All NetGenics activities under this Section 7.3 shall be charged
against Subscriber's then-available Service Hours, under guidelines as set forth
in EXHIBIT G attached hereto. Subscriber Software developed other than in
accordance with all provisions of this Section 7.3 herein shall void any
warranty rights.

8. SUBSCRIBER RESPONSIBILITIES
   ---------------------------

         8.1 The obligation of NetGenics to perform under this Agreement is
contingent upon Subscriber providing such cooperation as NetGenics may
reasonably request including, but not limited to, providing or performing the
following:

            (a) Sufficient and appropriate physical space for the Hardware at
each Designated Location, in a controlled area such as a data center or computer
room, where the hardware is physically secured and environmentally controlled;

            (b) Electrical power source in close proximity to the location of

and



                                       15
<PAGE>   16

            (f) Reasonable assistance of Subscriber's personnel.

            (g) Reasonable assistance and cooperation in the provision of
requested Support Services, as well as other activities within the scope of this
Agreement, for the term of the Agreement.

     8.2 It shall be understood by the parties that all Product(s) are intended
to be installed at their respective Designated Location(s) as mutually agreed,
and that Subscriber shall have all necessary facilities available for
installation and acceptance as agreed.

9. SUBSCRIPTION RELEASES
   ---------------------

     9.1 Subject to the provisions of Section 9.3 below, standard upgrades made
by NetGenics to the Subscription (such upgrades "Subscription Releases") at any
time during the term of this Agreement will be offered to Subscriber at no
additional charge.

     9.2 If any standard upgrades made to any of the Third Party Software by
their respective owners at any time during the term of this Agreement are
necessary for the Product's continued maintenance, then, at Subscriber's option,
it may purchase such upgrade from the Third Party Software vendor or, if
available, from NetGenics at NetGenics' then current prices. These upgrades
shall be installed at the Designated Location. Subscriber will be responsible
for the cost of the installation of any such upgrades (or if Service Hours are
available, such hours will count against the Service Hours) at NetGenics' then
current hourly rates. Failure by Subscriber to purchase such upgrades as are
identified by NetGenics as essential to the Subscription's continued maintenance
may result in Subscriber forfeiting its rights to receive future Subscription
Releases.

     9.3 NetGenics shall furnish the number of full sets of Documentation as
designated in EXHIBIT C for each Designated Location, at no charge to
Subscriber. NetGenics shall provide such updates to the furnished Documentation
as are necessary, in conjunction with Subscription Releases. NetGenics shall, at
Subscriber's request and at NetGenics' then current published prices, furnish
additional sets of the Documentation, together with any revisions therein or
additions thereto.

10. FEES
    ----

     10.1 Unless this Agreement is terminated pursuant to Section 2.3,
Subscriber shall pay to NetGenics consideration (the "Fee") in the amount of
[******] per year, to be paid on a quarterly basis, with the first payment of
[******] to be made within thirty (30) days after the delivery of an invoice,
prorated for any partial calendar quarter and for the no-charge trial period

is due. The Fee as set forth in this Section 10.1 may be changed to reflect
changes in the Designated Location(s) pursuant to Sections 5.9 through 5.13 of
this Agreement, and as amended on EXHIBIT C.

     10.2 If Subscriber has exhausted its available Service Hours for any
applicable calendar year, Subscriber shall pay to NetGenics, upon NetGenics'
request, fifty percent (50%) of all reasonable out-of-pocket expenses incurred
by NetGenics in performing Services for Subscriber under this Agreement
including, without limitation, expenses incurred for travel, meals, lodging,
long distance telephone calls, document reproduction, postage, and cost of
storage media such as disks and tapes.

     10.3 Subscriber shall pay when due any sales, use, excise, property or
other federal, state, local or foreign taxes, duties, tariffs or other
assessments (other than any tax based solely on the net income of NetGenics) and
related interest and penalties that NetGenics is at any time obligated to pay or
collect in connection with or arising out of the transactions contemplated by
this Agreement. Subscriber agrees to indemnify and hold harmless NetGenics from
any and all of such taxes, duties, tariffs or other assessments. If NetGenics
pays any such amounts which Subscriber is obligated to pay under this Section
10.3, Subscriber shall promptly reimburse NetGenics in an amount equal to the
amount so paid by NetGenics.

     10.4 Any payments due NetGenics hereunder which are not paid when due shall
bear interest at the lower of the rate of one and one-half percent (1.5%) per
month or the highest rate permitted by law.

11. SOURCE CODE
    -----------

     11.1 NetGenics agrees to make Subscriber a beneficiary under the NetGenics'
existing Source Code Escrow Agreement, which shall provide Subscriber with
access to the Source Code for supporting and maintaining the Licensed Program in
the event NetGenics ceases to do business in its regular course.

     11.2 NetGenics may make limited examples of Source Code available to
Subscriber, as needed and at NetGenics' sole discretion. All such Source Code
shall be treated as Confidential Information of NetGenics as set forth in this
Agreement.

12. PROPRIETARY RIGHTS
    ------------------

     12.1 Except for release of Source Code, as set forth in Section 11.1 above,
Subscriber acknowledges that NetGenics is the sole and exclusive owner of the
Software, Services and Documentation and the Source Code of the Software, and
all proprietary rights therein, including, without limitation, all associated
patents, copyrights and trade secrets rights.

     12.2 All proprietary notices incorporated in or fixed to the Licensed
Program or Documentation shall be duplicated by Subscriber on all copies or
extracts thereof and shall not be altered, removed or obliterated. A copyright
notice on the Licensed Program or Documentation does not, by itself, constitute
evidence of publication or public disclosure.

     12.3 NetGenics and Subscriber acknowledge that the other party's
Confidential Information constitutes commercially valuable proprietary trade
secrets, patent applications, patents, plant breeders' rights, plant variety
protection registration etc. of the disclosing party, including, without
limitation, copyrights, trade secrets and may include software for which patents
have been applied for or issued. The receiving party shall (i) not disclose or
allow access to the Confidential Information to any party other than its
employees, solely on a need-to-know basis, who have signed a nondisclosure
agreement conforming as to intent and effect to this Section 12; (ii) use its
best efforts to protect the Confidential Information against any unauthorized or
unlawful use, disclosure, dissemination or copying; (iii) not use any of the
Confidential Information other than as permitted under the terms of this
Agreement; (iv) not provide or disclose to third parties the Confidential
Information in any form, and (v) not provide or permit public access to the
Confidential Information in whole or in part, including, without limitation, by
computer networks, periodicals, newspapers or any other accessible or
distributed media.

13. TERM
    ----

     13.1 Unless sooner terminated as herein provided, this Agreement shall
commence on the Effective Date and shall terminate upon the third (3rd)
anniversary of the Effective Date (the "Term"). This agreement may be renewed
for subsequent one (1) year terms, at NetGenics' then current license fees, upon
mutual agreement within thirty (30) days of the expiration of the Term.

     13.2 Subscriber may terminate this Agreement any time after the first
anniversary of the Effective Date by providing thirty (30) days written notice
thereof to NetGenics.

     13.3 Either party may terminate this Agreement if the other party
materially breaches a provision of the Agreement, including, without limitation,
payment obligations, and fails to correct the breach within sixty (60) days
following written notice of the breach.



                                       18
<PAGE>   19

     13.4 If either party to this Agreement files a petition in bankruptcy, or
if a petition in bankruptcy is filed against it, or if it becomes insolvent, or
makes an assignment for the benefit of creditors or an arrangement pursuant to
any bankruptcy law, the other party shall have the right to terminate this
license upon thirty (30) days' written notice.

     13.5 Upon termination of this Agreement for any reason, Subscriber shall:
(i) pay immediately all amounts which are due and payable; (ii) have no further
right and license to use the Subscription or NetGenics' Confidential Information
(except as provided in Sections 13.6 and 13.7); (iii) return, at its cost, the
Product, together with any and all copies, modifications and merged portions in
any form, and all tangible embodiments of the Confidential Information, (unless
it provides assurances reasonably satisfactory to NetGenics that the
Documentation and Confidential Information and all copies thereof have been
destroyed). NetGenics shall have the right to supervise the return or
destruction of all such materials.

     13.6 In the event of termination for any reason other than as provided
under Section 2.3 of this Agreement, NetGenics shall provide any outstanding
Services for which Fees have been paid, and shall provide reasonable commercial
assistance to Subscriber in transferring any Subscriber data, held within the
Product prior to termination, into a mutually-agreed, machine-readable form.
Such assistance shall be provided at cost to Service Hours, and should remaining
Service Hours be exhausted, shall be provided at NetGenics' then-current hourly
rates. In addition, NetGenics shall maintain a tape back-up version of the
Product, in Subscriber's system configuration, for a period of five (5) years
after termination. Upon payment to NetGenics of consideration equal to the fair
market value of the Hardware then in use at Subscriber's Designated Location,
the aforementioned tape back-up version of the Product, along with the Hardware
then in use at Subscriber's Designated Location, shall be placed in escrow with
a mutually-agreed escrow agent. Subscriber shall have the right to request, and
NetGenics shall have the obligation to provide, access to the Product,
integrating Subscriber's data as of the date of termination, during the
above-referenced five-year period. Such access shall be subject to no less than
thirty (30) days' written notice from Subscriber, and shall be provided at
NetGenics then-current hourly rates, plus any and all necessary travel and other
expenses, including reasonable and actual expenses incurred for transportation,
meals, telephone, hardware rental, and shipping costs.

     13.7 In the event that Subscriber terminates this Agreement on or after the
third anniversary of the Effective Date, Subscriber shall be entitled, upon
payment of a consideration equal to one (1) year's Subscription Fee (as
designated on EXHIBIT C) in effect at the time of such termination, to continue
use of the Product for a period of eighteen (18) months, subject to the
following conditions: (i) Subscriber access shall be "read-only"; i.e. data may
be viewed using the Product, but no new data may be created or analyzed using
the Product, and (ii) no more than twelve (12) persons may have access



                                       19
<PAGE>   20

to the Product. NetGenics audit rights, as provided in Section 5.7, shall remain
in force during the above-described extension period.

14. REPRESENTATIONS, WARRANTIES AND LIMITATION OF LIABILITY
    -------------------------------------------------------

        14.1 NetGenics represents that it has the right and authority to enter
into this Agreement and grant the license contained herein.

        14.2 NetGenics warrants to Subscriber from the date of acceptance and
for the Term of this Agreement that: (i) the Product, any custom software
modules developed by NetGenics for Subscriber and any Subscriber Software will
substantially conform to the Documentation, provided that it is used at the
Designated Location and with the environment for which it was designed; (ii) the
Product and any custom software modules developed by NetGenics for Subscriber
will process dates accurately prior to, during and after the calendar year 2000
(including, without limitation, accurate century recognition, ability to
accommodate same century and multi-century formulas and date values and
interface values reflecting the appropriate century); and, (iii) any media on
which the Licensed Program, any custom software modules developed by NetGenics
for Subscriber and the Documentation are distributed will be free from defects
in materials and workmanship under normal use and service.

        14.3 NetGenics' entire liability and Subscriber's sole and exclusive
remedy in the event of substantial nonconformity of the Licensed Program or
defective media or Documentation, shall be, at NetGenics' sole discretion, the
correction or work-around of such substantial errors in the Licensed Program,
replacement of the defective media or Documentation, or a refund of a pro-rata
portion of the subscription fee, corresponding to the period of time in which
the Product was non-usable due to non-conformance. Any correction of substantial
errors to the Licensed Program or any replacement media or documentation which
is supplied is warranted for the remainder of the original warranty period.

        14.4 Such services and any required warranty service pursuant to this
Section 14 will be performed, by mutual agreement, (i) by telephonic
communication, (ii) via modem from NetGenics' facility, (iii) by NetGenics at
the site of Subscriber or (iv) otherwise as determined by NetGenics and agreed
by Subscriber.

        14.5 The warranty contained in Section 14.2 shall be void and of no
effect in the event (i) the Product has been modified, altered or changed in any
manner by Subscriber or any party acting on behalf of Subscriber (other than as
set forth herein), (ii) if any media has been damaged as a result of accident,
misuse or abuse by Subscriber or any party acting on behalf of Subscriber (other
than by NetGenics or its authorized representatives), or (iii) any substantial
nonconformity of the Product is due, through no fault of NetGenics, to the
failure of, or defects in, any Third Party Software used in



                                       20
<PAGE>   21

connection with the Licensed Program, including any Subscriber Software
developed other than as provided in Section 7.3 of this Agreement.

        14.6 EXCEPT AS SET FORTH IN SECTIONS 14.1 AND 14.2, NETGENICS EXPRESSLY
DISCLAIMS ALL WARRANTIES OR REPRESENTATIONS WITH RESPECT TO THE SUBSCRIPTION
(INCLUDING, WITHOUT LIMITATION, ANY RESULTS CREATED FROM USE OF THE SUBSCRIPTION
HEREUNDER), EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

        14.7 NETGENICS SHALL NOT BE LIABLE TO SUBSCRIBER FOR ANY DIRECT DAMAGES
OR CLAIMS IN EXCESS OF THE FEES PAID BY SUBSCRIBER HEREUNDER. NETGENICS SHALL
NOT BE LIABLE TO SUBSCRIBER OR ITS AFFILIATES FOR ANY INDIRECT, SPECIAL,
CONSEQUENTIAL, EXEMPLARY OR INCIDENTAL DAMAGES (INCLUDING, WITHOUT LIMITATION,
LOST REVENUES, ANTICIPATED REVENUES OR PROFITS RELATING TO THE SAME) ARISING
FROM ANY CLAIM RELATING DIRECTLY OR INDIRECTLY TO THIS AGREEMENT, WHETHER A
CLAIM FOR SUCH DAMAGES IS BASED ON WARRANTY, CONTRACT, TORT (INCLUDING, WITHOUT
LIMITATION, NEGLIGENCE OR STRICT LIABILITY), EVEN IF AN AUTHORIZED
REPRESENTATIVE OF NETGENICS IS ADVISED OF THE LIKELIHOOD OR POSSIBILITY OF SAME.
SUBSCRIBER ACKNOWLEDGES AND AGREES THAT PAYMENT BY NETGENICS OR RETENTION BY
SUBSCRIBER OF DIRECT DAMAGES AS LIMITED BY THE FOREGOING SENTENCE SHALL BE
SUBSCRIBER'S SOLE AND EXCLUSIVE REMEDY IN EXHAUSTION OF ALL OTHER REMEDIES UNDER
THIS AGREEMENT, AT LAW OR IN EQUITY, AND THAT SUCH REMEDY SHALL NOT BE DEEMED OR
ALLEGED BY SUBSCRIBER TO HAVE FAILED OF ITS ESSENTIAL PURPOSE. IN NO EVENT SHALL
NETGENICS BE LIABLE FOR ANY DAMAGES CAUSED BY SUBSCRIBER'S OR ANY THIRD PARTY'S
ACTS OR OMISSIONS.

15. INDEMNIFICATION
    ---------------

        15.1 NetGenics shall indemnify and hold harmless Subscriber against any
costs, fees or damages arising out of, or related to, any claim that
Subscriber's authorized use or possession of the Product or that the license
infringes or violates any United States or European Patent Office copyright,
patent or trademark of any third party; provided however, that (i) NetGenics has
sole control of the defense and/or settlement, (ii) Subscriber notifies
NetGenics promptly, but no later than thirty (30) days upon receipt by
Subscriber of notice of such claim in writing of each such claim or suit and
gives NetGenics all information known to Subscriber relating thereto, and (iii)
Subscriber cooperates with NetGenics in the settlement and/or defense.
Subscriber shall be reimbursed for all reasonable out-of-pocket expenses
incurred in providing any



                                       21
<PAGE>   22

cooperation requested by NetGenics. Failure of Subscriber to so notify NetGenics
will result in the forfeiture by Subscriber of its rights to indemnification
under this Section 15.

        15.2 In the event that all or any part of the Product is, or in the
opinion of NetGenics may become, the subject of any claim or suit for
infringement of any third party trademark, patent or copyright, or if
Subscriber's use of the Product is permanently enjoined, NetGenics shall, in its
sole discretion and at its expense, do one of the following: (i) procure for
Subscriber the right to use the Product or the affected part thereof; (ii)
replace the Product or affected part with other suitable software, hardware and
documentation; (iii) modify the Product or affected part to make it
non-infringing; or (iv) refund the license fee paid by Subscriber and terminate
the licensed rights granted herein. Any such refund shall be prorated to reflect
the reasonable value for the use of the Subscription. NetGenics shall be
obligated to advise Subscriber of its intended activities within thirty (30)
days of initial notification of infringement. In the event NetGenics elects
options (ii) or (iii) above, and the resulting Product lacks significant
functionality as described in the Documentation, Subscriber may elect to
terminate this Agreement and incur no further cost nor obligation hereunder.

        15.3 NetGenics shall have no obligations under this Section 15 to the
extent a claim is based upon any of the following: (i) the Product or any
portion thereof has been modified, altered or changed in any manner by
Subscriber or any party acting on behalf of Subscriber (other than by NetGenics
or its authorized representatives), if such infringement would have been avoided
in the absence of the use of such altered Product; (ii) the combination,
operation or use of the Product with software which was not provided by
NetGenics, if such infringement would have been avoided in the absence of such
combination operation or use; or (iii) the use of the Software and Documentation
on or in connection with a computer system or hardware components which have not
been approved by NetGenics and/or which are used at a location other than at the
Designated Location without NetGenics' prior written approval.

        15.4 This Section 15 states NetGenics' entire liability for any alleged
infringement by the Product or any part thereof.

16. GENERAL
    -------

        16.1 Sections 5.8, 12.1 through 12.3, 13.5 through 13.7, 14.1, 14.3,
14.5 through 14.7, Article 15 in its entirety, 16.1, 16.7, 16.13 and 16.15 shall
survive the termination of this Agreement for any reason.

        16.2 This Agreement and all Exhibits attached hereto and incorporated
herein by this reference contain the entire agreement between the parties hereto
with respect to the subject matter hereof and supersedes any previous
understandings or agreements, whether written or oral, in respect of such
subject matter.



                                       22
<PAGE>   23

        16.3 This Agreement shall be binding upon and inure to the benefit of
the parties, their successors and assigns. This Agreement or any portion
thereof, or any right or responsibility hereunder, shall not be assignable
(except to a successor or Affiliate) by Subscriber without the prior written
consent of NetGenics, such consent not to be unreasonably withheld. Any
attempted assignment which does not comply with the terms of this Section 16.3
shall be void and of no effect.

        16.4 None of the terms of this Agreement shall be deemed to be waived or
amended by either party unless such a waiver or amendment specifically
references this Agreement and is in a writing signed by the party to be bound.

        16.5 The illegality, invalidity or unenforceability of any part of this
Agreement shall not affect the legality, validity or enforceability of the
remainder of this Agreement. If any part of this Agreement shall be found to be
illegal, invalid or unenforceable, this Agreement shall be given such meaning as
would make this Agreement legal, valid and enforceable in order to give effect
to the intent of the parties.

        16.6 All communications, notices and exchanges of information
contemplated herein or required or permitted to be given hereunder shall be in
writing and shall be deemed properly given when personally delivered, or when
one delivers it to an established courier service, with fees prepaid, or
transmits it by facsimile (with hard copy to follow), addressed to the other
party to the addresses set forth on the first page of this Agreement (or such
other address of which such party shall have given written notice).

        16.7 Both Subscriber and NetGenics acknowledge that a breach or failure
to comply with any of the provisions of this Agreement (other than payment
obligations) will irreparably harm the business of the other party, and that
neither Subscriber nor NetGenics will have an adequate remedy at law in the
event of such breach or non-compliance. Therefore, Subscriber and NetGenics
acknowledge that either party shall be entitled to injunctive relief and/or
specific performance without the posting of bond or other security, in addition
to whatever other remedies it may have, at law or in equity, in any court of
competent jurisdiction against any acts of such breach or non-compliance.

        16.8 Subscriber will be responsible for the payment of all taxes based
on work performed or products delivered pursuant to this Agreement, except for
taxes based on NetGenics' net income.

        16.9 Each party has the right to use the name, logos and trademarks of
the other party in publicity releases or advertising, including customer lists,
or for other promotional purposes, upon the prior written approval of the other
party, such approval not to be unreasonably withheld.

        16.10 Nothing herein shall be construed to create any relationship of
employer and employee, agent and principal, partnership or joint venture between
the parties. Neither



                                       23
<PAGE>   24

party shall assume, either directly or indirectly, any liability of or for the
other party. Neither party shall have the authority to bind or obligate the
other party and neither party shall represent that it has such authority.

        16.11 Notwithstanding anything to the contrary contained in this
Agreement, neither Subscriber nor NetGenics will be responsible for any failure
to perform its obligations hereunder caused by strikes, lockouts, riots,
epidemics, war, governmental regulations, fire, communication line failures,
power failures, acts of God or other causes beyond its control, including acts
or omissions of third parties, and the occurrence of any such event will toll
the time period provided in this Agreement for performance by NetGenics or
Subscriber.

        16.12 The article and section headings in this Agreement are for
reference purposes only and will not be deemed to be a part of this Agreement,
nor are they intended to describe, interpret, define or limit the scope or
extent of this Agreement or any provision hereof.

        16.13 This Agreement shall be governed by and construed in accordance
with the domestic laws of the State of Delaware, United States of America,
without giving effect to its choice of law or conflict of law provisions.

        16.14 If the parties cannot resolve a dispute arising out of or in
connection with this Agreement, then any party may, upon written notice to the
other, have such dispute referred to their respective officers designated below
or their successors, for attempted resolution by good faith negotiations within
thirty (30) days after such notice is received:

               For NetGenics:       President

               For Subscriber:      Head of Biotechnology Research

Any such dispute which is not so resolved between the parties or the designated
officers within such thirty (30) day period shall, upon written notice from one
Party to be resolved by final and binding arbitration under the then current
Licensing Agreement Arbitration Rules of the American Arbitration Association
("AAA"). If the claim is filed by one party, then the venue for arbitration
shall be proximate to that of the other party. The arbitration shall be
conducted by a panel of three arbitrators who are knowledgeable in the subject
matter which is at issue in the dispute (the "Panel"). Each party shall have the
right to appoint one member of the Panel, with the third member to be mutually
agreed upon by the two Panel members appointed by the parties or, failing such
agreement, to be selected according to the AAA rules. Notwithstanding the
foregoing, no panel member appointed in pursuit to this Section 16.14 shall be a
resident of the state of Ohio or the Principality of Belgium. In conducting the
arbitration, the panel shall determine what discovery will be permitted,
consistent with the goal of limiting the cost and time which the parties must
expend for discovery (and provided that the Panel shall permit such



                                       24
<PAGE>   25

discovery deemed necessary to permit an equitable resolution to the dispute).
The decision of the Panel shall be in writing and shall set forth the basis
therefor. The Panel shall also determine the steps, if any, that a Party should
take to correct any failure or breach by such Party pertaining to any such
dispute. The Parties shall share equally the Panel's fees and expenses. The
decision of the Panel shall be final and may be enforced by the Party in whose
favor it runs, and such award may be enforced and executed upon in any court
having jurisdiction over the Party against whom the enforcement of such an award
is sought.

        16.15 During the Term of this Agreement and for one (1) year thereafter,
neither Subscriber nor NetGenics shall directly solicit for employment any
employee of the other party who was directly involved with the performance of
this Agreement, without the prior consent of that party. Notwithstanding the
foregoing, the provision of this Section 16.15 shall not prohibit either party
from hiring employees of the other party who have applied for positions on their
own and without solicitation by the hiring party.


        16.16 Upon execution of this Agreement, NetGenics and Subscriber agree
to cooperate in the preparation of a joint press release stating that the
parties have entered into a software license and service agreement. NetGenics
hereby warrants that it will not use any trademark or make reference to products
or services of Subscriber or its subsidiaries without obtaining the prior
written permission of Subscriber.

               IN WITNESS WHEREOF the parties hereto have caused this Software
License Agreement to be executed by their duly authorized representatives as of
the date first above written.

NETGENICS, INC.
CLIENT SUPPORT AND ESCALATION PROCEDURES

The Client Support Team

A team of Client Support Professionals supports each NetGenics client, each with
specialized knowledge of both SYNERGY software and services and the particular
needs of the individual client. Each team is made of individuals trained in
areas of Biological Research, Bioinformatics, and Hardware and Software
Technical Support. Each client is assigned an Account Manager, who is
responsible for maintaining up-to-date communications with the client
organization and the team. Customization concerns should be directed through the
Account Manager. The purpose of the Support Team is to service all the needs of
the organization, Information Systems (IS) personnel, and end-users.

System monitoring

NetGenics will monitor the server at the customer site, to assist in maintaining
the performance and integrity of the system, as well as to assist in problem
determination and resolution. Remote monitoring of the server is the preferred
method, and is provided without additional cost of Service Hours to the
customer. The customer may, at its option, elect not to provide remote
monitoring access to the NetGenics Client Support Team. In this case, a
Technical Support Representative will conduct regular monitoring of the system
on-site. This time will be charged against the Customer's Available Service
Hours, at an agreed number of hours per Calendar Quarter, plus reimbursement to
NetGenics of incurred travel expenses.

Support Processes

Incoming calls and email reports are handled by a 1st tier Client Service
Specialist. In many cases, this person will be able to resolve most incidents as
they are reported. Whenever possible, calls will be routed live to a member of
the Client Support Team. If no person is immediately available or it is after
business hours (Normal business hours Monday - Friday 0900 to 1800h Belgian
Time), someone will return the call as soon as possible and within the times
outlined (refer to Table 1) to begin the resolution process.

EMAIL WILL BE HANDLED DURING NORMAL BUSINESS HOURS ONLY. An initial reply will
be automatically generated instructing the sender on what to do if the problem
requires more prompt assistance. Incidents reported via email will be addressed
as soon as possible and at least by the end of the next business day.

All incidents are logged and prioritized according to Table 1 by the NetGenics
Support Team, and updates are issued to the Account Manager and clients on a
regular basis (refer to Table 1), according to the priority of the incident.
Each incident is assigned an Incident Number, by which the incident may be
tracked until resolution. All work relating to the incident resolution is
attached to this incident number.

If the 1st tier support person is unable to resolve the call or email at the
time of the call, the call or email will be routed to the appropriate second or
third tier level support, as outlined below (refer to Table 1). Whenever
possible, an unresolved call will be routed live to the member of the Client

Support Team who is best trained to handle the particular incident. If there are
no appropriate support personnel immediately available, a member of Client
Services will respond within the indicated times (refer to Table 1) to continue
the resolution process.

Automatic Escalation of Incidents

Incidents unresolved after the incoming or initial return call will be escalated
according to the chart below. Escalation periods are based on the priority of
the incident. NetGenics will escalate incidents to second tier Scientific or
Technical support, or third tier Development and Quality Assurance support as
necessary to aid in resolution of the incident.
