                          CONSULTING SERVICES AGREEMENT

        This Intellectual Property Transfer and Consulting Services Agreement
("Agreement") is entered into as of March 31, 2000 (the "Effective Date"), by
and between Informatica Corporation, a Delaware corporation ("Informatica"), and
PricewaterhouseCoopers LLP, a registered Delaware limited liability partnership
("PwC").

        1.     Transfer of Intellectual Property; License to Informatica.

               1.1 Subject to the terms and conditions of this Agreement, at the
Closing, PwC agrees to transfer, assign and convey to Informatica all right,
title and interest in and to the following: (i) the Q-manufacturing software and
related materials described on Exhibit A-1 hereto (the "Q-Manufacturing IP");

1.1 above includes the transfer, assignment and conveyance by PwC to Informatica
of all intellectual property and proprietary rights relating solely to the
Transferred IP, including (without limitation) all patents, patent rights,

to the Transferred IP.

               1.4 PwC shall not retain any copies (including electronic copies)
of any of the software or materials transferred to Informatica pursuant to
Section 1.3 above, except such copies of such software (in object code form

engage in or authorize any act that would constitute an infringement or
misappropriation of any intellectual property or proprietary rights relating to
the Transferred IP.

               1.5 Effective at the Closing Date and subject to Section 1.6, to
the extent PwC is not otherwise restricted from doing so, PwC hereby grants to
Informatica a non-exclusive, fully-paid, perpetual, irrevocable, worldwide right
to use, display, perform, distribute, modify, sublicense, make and sell products
based on, and prepare derivative works based upon the Licensed Assets. For
purposes of this Section 1.5, the "Licensed Assets" shall mean any and all
software, object code, source code and related documentation, know-how,
processes and other intangible assets which (i) are not included in the
Transferred IP, (ii) are necessary for the utilization of the Transferred IP or
are embedded in the Transferred IP, and (iii) are owned by PwC.

               1.6 The Licensed Assets that are licensed to Informatica by PwC
hereunder are licensed on an "as is" basis without any representations or
warranties of any kind whatsoever, and PwC expressly disclaims the implied
warranties of merchantability, non-infringement and fitness for a particular
purpose. Informatica acknowledges that it is assuming all risks and
responsibilities for its use of the Licensed Assets licensed hereunder.

               1.7 Effective at the Closing Date and subject to Section 1.8, to
the extent PwC is not otherwise restricted from doing so, PwC shall grant to
Informatica a non-exclusive, fully-paid, perpetual, irrevocable, worldwide right
to use, display, perform, distribute, modify, sublicense, make and sell products
based on, and prepare derivative works based upon the Licensed Intellectual
Property. For purposes of this Section 1.7, the "Licensed Intellectual Property"
shall mean any know-how and processes which (i) are owned by PwC, and (ii) are
embedded by the PwC Consultants (as defined below) in any products, "works for
hire" or other intellectual property of Informatica pursuant to the performance
of the consulting services by the PwC Consultants as provided for in Section 3.

               1.8 The Licensed Intellectual Property that is licensed to
Informatica by PwC hereunder is licensed on an "as is" basis without any
representations or warranties of any kind whatsoever, and PwC expressly

Closing. Subject to compliance with applicable securities laws, PwC shall be
entitled to transfer a portion of the Shares (in an amount to be determined by
PwC) to Concept Information Systems, Inc. ("CIS"). CIS shall take and hold any
transferred Shares subject to all rights and restrictions applicable thereto,
including without limitation, piggyback registration rights in accordance with
Section 2.2.

               2.2 The Shares will not be registered under the Securities Act of
1933, as amended (the "Act"), or qualified under any state securities laws. PwC,
including any transferee of PwC, shall have piggyback registration rights with
respect to the Shares pursuant to a Registration Rights Agreement between PwC
and Informatica the same date hereof, (the "Rights Agreement"), a copy of which
is attached hereto as Exhibit B, subject to PwC (and any such transferee)
agreeing to be bound by all terms of the Rights Agreement applicable to such
rights. Except for restrictions on transfer pursuant to applicable securities
laws and as set forth in the Rights Agreement, the Shares will not be subject to
restrictions on transfer or resale.

        3.     Consulting Services.

               3.1 Prior to the Closing, Informatica will make offers of
employment to the six (6) PwC employees who are members of PwC's Q-manufacturing
team and whose names are set forth on Exhibit C attached hereto. In the event
two (2) or more of such PwC employees decline the employment offer from
Informatica, PwC shall provide to Informatica consulting services of a number of
full-time equivalent employees of PwC, who shall be agreed upon by PwC and
Informatica prior to the Closing, with like skills for a period of two (2) years
following the Closing, such that the total of the number of such employees and
the number of PwC employees who have accepted the foregoing offers of employment
equals five (5). Such PwC employees (other than those who accept employment with
Informatica) shall provide consulting services to Informatica as provided in
Section 3.5 below, and each such employee shall be deemed to be a PwC Consultant
(as defined below).

               3.2 PwC will cause three (3) PwC employees, who are members of
PwC's HR services team and who shall be agreed upon by PwC and Informatica prior

with Section 3.5 to Informatica for a period of one (1) year following the
Closing.

               3.3 PwC will cause six (6) PwC employees, who are members of

prior to the Closing, to provide consulting services pursuant to and in
accordance with Section 3.5 to Informatica for a period of two (2) years
following the Closing.

               3.4 PwC will cause two (2) PwC employees with data warehousing

by PwC and Informatica prior to the Closing, but shall in no event commence more
than thirty (30) days following the Closing.

               3.5 The PwC employees referred to in Sections 3.1 (if
applicable), 3.2, 3.3, and 3.4 above are hereinafter referred to as the "PwC
Consultants." PwC shall cause the PwC Consultants to devote all of their working
time and efforts (which in any event shall be full-time employment) to
consulting projects in their respective areas of expertise as reasonably
requested by Informatica; provided, however, the PwC Consultants shall be
entitled to attend PwC training and meetings. PwC shall have the right to
substitute another PwC employee for such PwC Consultant, subject to the
reasonable approval of Informatica. PwC shall give Informatica 90 days prior
written notice- in the event that a PwC Consultant will cease to be available to
provide such consulting services, provided, however, such 90 day written notice
requirement shall not apply in the event the PwC Consultant resigns or is
terminated by PwC in which case notice will be given by PwC as soon as
practicable. The services performed by the PwC Consultants shall be performed in
accordance with the terms and conditions set forth on Exhibit D attached hereto
and incorporated herein by this reference. Informatica acknowledges that the PwC
Consultants are going to be performing the services under Section 3 under the
supervision and control of Informatica. As a result, but subject to Section
11.1(e) below, PwC shall not be responsible for and makes no representations or
warranties with respect the performance of the services by the PwC Consultants.

               3.6 PwC shall be responsible for all compensation and benefits to
be paid to the PwC Consultants. Without limiting the generality of the
foregoing, (i) no PwC Consultant shall be eligible to participate in any of
Informatica's stock option, stock purchase or other employee benefit plans,
fringe benefit programs, life or disability insurance programs or similar plans
or programs, and (ii) Informatica shall not provide workers' compensation,
disability insurance, Social Security or unemployment compensation coverage or
any other statutory benefits to any PwC Consultant. PwC shall comply, at its
expense, with all laws, rules and regulations relating to the matters referenced
in the foregoing clause (ii) with respect to the PwC Consultants and with all
other laws, rules and regulations relating to the terms and conditions of
employment of the PwC Consultants.

               3.7 In the event that any PwC Consultant or any PwC employee
hired by Informatica pursuant to Section 3.1 above ceases to be available to
Informatica on a full-time basis during the applicable period following the
Closing (which will be deemed to be a one (1) year period in the case of any PwC
employee hired by Informatica), or if Informatica reasonably determines that the
services being provided to Informatica by such individual are not satisfactory,
PwC shall promptly provide a substitute reasonably acceptable to Informatica for
the remainder of the applicable time period.

               3.8 Informatica will have sole and exclusive ownership of and all
right, title and interest in and to all software and other works of authorship,

conceived or reduced to practice by the PwC Consultants pursuant to the services
performed hereunder during the applicable periods during which they are
providing services to Informatica hereunder. The foregoing Informatica ownership
rights include sole and exclusive ownership of all patents, copyrights, trade
secret rights, trademarks, trade names, service marks and other intellectual
property and proprietary rights covering the foregoing subject matter.
Notwithstanding the foregoing, (i) PwC's administrative working papers;
including administrative papers, such as work plans, time sheets and so on ("PwC
Work Papers"), and PwC's Confidential Information (as defined below) shall
belong exclusively to PwC, and (ii) the ideas, concepts, know-how, techniques,
inventions, discoveries, improvements and other information generally relating
to information processing, telecommunications or business process re-engineering
or design, developed during the course of this Agreement by the PwC Consultants,
may be used by either party, without an obligation to account, in any way it
deems appropriate, including without limitation by or for its clients or
customers, notwithstanding any provision in this Agreement to the contrary;
provided, however, that the foregoing shall not be deemed to grant PwC any
rights or licenses in respect of Informatica's patents or copyrights or to
relieve PwC from its obligations under Section 12.1 hereunder. PwC Work Papers
shall not include lab notebooks and other materials that include any
intellectual property of Informatica which is developed, improved, modified or
enhanced as a result of the services performed pursuant to section 3 herein.

               3.9 Notwithstanding anything to the contrary herein, PwC shall
retain the right to (i) develop for its clients products and capabilities that
are similar to or competitive with the Transferred IP and any products and
capabilities developed, modified, enhanced or improved hereunder, (ii) work with
third parties to develop products and/or capabilities that may be competitive
with Informatica's products or services. Notwithstanding the foregoing, except
as permitted pursuant to Section 4.1, in no event shall (x) PwC make any use of
any of Informatica's patents, copyrights, trade secrets or other intellectual
property or proprietary rights, including the Transferred IP, and (y) a
particular PwC Consultant participate, directly or indirectly, in any such PwC
development efforts during the applicable period during which such PwC
Consultant is providing services to Informatica hereunder. Following the
applicable period during which a PwC Consultant is providing services to
Informatica hereunder, PwC shall not be prohibited from utilizing Residual
Information (as defined below) of PwC and/or such PwC Consultant; provided,
however, that the foregoing shall not be deemed to grant PwC any rights or
licenses in respect of Informatica's patents or copyrights or to relieve PwC
from its obligations under Section 12.1 hereunder. "Residual Information" shall
mean information that is both (a) obtained by PwC and/or the PwC Consultants as
a result of performing consulting services for Informatica hereunder, and (b)
retained in the unaided memories (and not memorialized or otherwise recorded in
writing or other tangible or electronic form) of the PwC Consultants or other
PwC personnel and not memorized by them for the purpose of utilizing such
information.

        4.     License to PwC.

               4.1 Effective as of the Closing and the transfer of the

source code form thereof. PwC shall not have the right to use the
Q-Manufacturing IP to develop a product for general release. PwC shall not make
the Q-Manufacturing IP available, in whole or in part, to any PwC client or any
other person or entity for any purpose other than training and demonstration
purposes.

               4.2 Effective as of the Closing and the transfer of the HR IP to
Informatica, and subject to the limitations set forth in this Section 4,
Informatica hereby grants to PwC a non-exclusive, non-transferable (except to a
PwC Successor), fully-paid, perpetual license, to use, display, perform,
distribute, modify, enhance, sublicense, make and sell products based on and
prepare derivative works based upon the HR IP in connection with (i) training

performance of implementation and other consulting services for PwC's clients,
and (iv) building custom solutions ("Custom Solution") for PwC's clients
(including embedding the HR IP therein) so long as PwC adds significant value to
the HR IP in connection with building a Custom Solution. Without limiting the
generality of the foregoing, PwC shall have the right to develop, modify,
improve, enhance, and prepare derivative works based upon the HR IP (the
"Enhanced IP") in connection with building Custom Solutions. PwC shall have the
right to sublicense the use of the HR IP and the Enhanced IP to any client for
which PwC builds a Custom Solution. PwC shall have the right (i) to be provided
or have access to any source code listing for the HR IP, and (ii) to
disassemble, decompile or reverse engineer the object code form of the HR IP or
otherwise derive the source code form thereof, in each case for purposes of
exercising PwC's rights under this Section 4.2. Notwithstanding the foregoing,

kind whatsoever, and Informatica expressly disclaims the implied warranties of
merchantability, non-infringement and fitness for a particular purpose. PwC

the Transferred IP licensed hereunder.

        5.     Intentionally Left Blank

        6.     Assumed Obligations.

               6.1 Subject to the terms and conditions hereof, as of the Closing
Date, pursuant to an Assignment and Assumption Agreement, PwC shall assign and
transfer and Informatica shall assume the obligations set forth on Exhibit E
(the "Assumed Obligations"). Notwithstanding anything to the contrary contained
herein, (i) Informatica is not assuming, and the Assumed Obligations shall not
include, any liabilities that have arisen or accrued prior to the Closing, and
(ii) Informatica will only be responsible for, and the Assumed Obligations shall
only include, liabilities that have been accurately and completely set forth on
Exhibit E.

               6.2 PwC will be solely responsible for obtaining any necessary
customer or other third-party consents to Informatica's assumption of the
Assumed Obligations. PwC will be responsible for performing the CIS Obligations
and any and all Q-Liabilities that are not Assumed Obligations.

        7.     Joint Marketing Obligations.

               7.1 Exhibit F attached hereto sets forth the parties' joint
marketing obligations. Except as otherwise set forth on Exhibit F, such
obligations shall remain in effect for a period of two (2) years following the
Closing.

               7.2 For a period of one (1) year following October 1, 2000, PwC
will be Informatica's preferred systems integrator for Informatica's eCRM,
eBusiness Operations, and eProcurement application suites (collectively, the
"Informatica Products"), which may also include: (i) the product currently known
as "Q-Manufacturing" which is being transferred to Informatica hereunder as part
of the Transferred IP and any enhancements, modifications, upgrades,
improvements or derivative works relating thereto, and (ii) any products
developed, enhanced, improved, upgraded or modified and any derivative works
incorporating the HR templates included within the Transferred IP, and (iii) any
products developed, enhanced, improved, upgraded or modified and any derivative
works incorporating the CRM content on the following terms and conditions. In
connection therewith:

                    7.2.1. In the event that Informatica intends to undertake a
project that will require third-party implementation of an Informatica Product,
Informatica will give PwC notice thereof as soon as practicable to permit PwC to
submit a proposal to Informatica's client;

<PAGE>   8
                    7.2.2. PwC shall have the right to decline to submit a
proposal to Informatica's client, in PwC's sole discretion;

                    7.2.3. In the event that PwC timely submits a proposal,
Informatica will communicate to its client that PwC is Informatica's preferred
implementor for the applicable Informatica Product; and

                    7.2.4. Informatica's client shall have the sole discretion
whether or not to accept PwC's proposal, and Informatica shall have no liability
to PwC or restrictions on Informatica's ability to work with such client in the
event that such client rejects PwC's proposal.

               7.3 PwC and Informatica shall amend the Reseller Agreement
currently in place between the parties to provide for PwC to be a reseller of
the Transferred IP and any new products developed pursuant to or in connection
with the services performed under Section 3. The parties will negotiate in good
faith the terms of such amended Reseller Agreement. In connection therewith, so
long as the Reseller Agreement is in effect, PwC shall be entitled to resell
Informatica products at the same or a lower price as that offered to other sales
agents (resellers) or customers of Informatica who agree to similar terms with
respect to volume, minimums, term and other material provisions.

        8.      Representations and Warranties of PwC. PwC represents and
warrants to Informatica as follows:

               8.1 PwC is a limited liability partnership duly organized,
validly existing and in good standing under the laws of the State of Delaware.
PwC has all necessary partnership power and authority to enter into this
Agreement and perform its obligations hereunder. The execution, delivery and
performance of this Agreement have been duly authorized by all necessary
partnership action on the part of PwC. This Agreement constitutes the legal,
valid and binding obligation of PwC, enforceable against PwC in accordance with
its terms.

               8.2 PwC owns all right, title and interest in and to the
Transferred IP, and no other person or entity possesses any ownership rights
with respect thereto. The Transferred IP and the reproduction, use and
distribution thereof do not infringe, misappropriate or violate the copyrights,
trade secret rights, trademarks, trade names, service marks or other
intellectual property or proprietary rights or, to the knowledge of PwC, the
patents of any person or entity anywhere in the world. PwC has not received any
communication from any third party alleging any such infringement,
misappropriation or violation.

               8.3 Exhibit G attached hereto lists all licenses and other rights
that PwC has granted to any person or entity in respect of the Transferred IP.
PwC represents and warrants that Exhibit G is accurate and complete and that PwC
has provided to Informatica true and complete copies of all written agreements,
and accurate and

complete summaries of all non-written arrangements, granting any such licenses
or other rights.

               8.4 Except for the possible transfer to CIS contemplated in
Section 2.1 and any assignment of Shares made in connection with the anticipated
restructuring of PwC (the "Restructuring"), which in any event shall comply with
all applicable securities laws, the Shares will be acquired for investment for
PwC's own account, not as a nominee or agent, and not with a view to the resale
or distribution of any part thereof, and PwC has no present intention of
selling, granting any participation in, or otherwise distributing the same.

               8.5 PwC believes that it has received all the information it
considers necessary or appropriate for deciding whether to acquire the Shares
hereunder.

               8.6 PwC acknowledges that it is able to fend for itself, can bear
the economic risk of its investment, and has such knowledge and experience in
financial or business matters that it is capable of evaluating the merits and
risks of the investment in the Shares.

               8.7 PwC is an "accredited investor" within the meaning of
Securities and Exchange Commission ("SEC") Rule 501 of Regulation D, as
presently in effect.

               8.8 PwC understands that the Shares are characterized as
"restricted securities" under the federal securities laws inasmuch as they are
being acquired from Informatica in a transaction not involving a public offering
and that under such laws and applicable regulations such securities may be
resold without registration under the Act only in certain limited circumstances.
In this connection, PwC represents that it is familiar with SEC Rule 144, as
presently in effect, and understands the resale limitations imposed thereby and
by the Act.

               8.9 Without in any way limiting the representations set forth
above, PwC further agrees not to make any disposition of all or any portion of
the Shares unless and until:

                      (a) There is then in effect a registration statement under
the Act covering such proposed disposition and such disposition is made in
accordance with such registration statement; or

                      (b) (i) PwC shall have notified Informatica of the
proposed disposition and shall have furnished Informatica with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii) if
reasonably requested by Informatica, PwC shall have furnished Informatica with
an opinion of counsel reasonably satisfactory to Informatica that such
disposition will not require registration of such Shares under the Act. It is
agreed that Informatica will not require opinions of counsel for transactions
made pursuant to Rule 144 except in unusual circumstances.

               8.10 It is understood that the certificates evidencing the Shares
shall bear the following legend: "These securities have not been registered
under the Securities Act of 1933, as amended. They may not be sold, offered for
sale, pledged or hypothecated in the absence of a registration statement in
effect with respect to the securities under such Act or an opinion of counsel
satisfactory to the Company that such registration is not required or unless
sold pursuant to Rule 144 of such Act."

        9.      Representations and Warranties of Informatica. Informatica
represents and warrants to PwC as follows:

               9.1 Informatica is a corporation duly organized, validly existing
and in good standing under the laws of the State of Delaware. Informatica has
all necessary corporate power and authority to enter into this Agreement and
perform its obligations hereunder. The execution, delivery and performance of
this Agreement have been duly authorized by all necessary corporate action on
the part of Informatica. This Agreement constitutes the legal, valid and binding
obligation of Informatica, enforceable against Informatica in accordance with
its terms.

               9.2 The Shares have been duly authorized and, when issued in
accordance with the terms of this Agreement for the consideration set forth
herein, will be validly issued, fully-paid and nonassessable.

               9.3 Informatica has filed all reports required to be filed by it
with the SEC pursuant to the Act and the Securities Exchange Act of 1934, as
amended (all such reports and amendments thereto, collectively, the "SEC
Reports"). None of the SEC Reports, as of their respective dates (as amended
through the date hereof), contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading. Each of the balance sheets (including the related notes)
included in the SEC Reports fairly presents the consolidated financial position
of Informatica and its subsidiaries as of the date thereof, and the other
related statements (including the related notes) included therein fairly present
the results of operations and the changes in cash flows of Informatica and its
subsidiaries for the respective periods set forth therein, all in conformity
with GAAP consistently applied during the periods involved, except as otherwise
noted therein and subject, in the case of the unaudited interim financial
statements, to (i) normal year end adjustments which would not in the aggregate
be material in amount or effect and (ii) the permitted exclusion of all
footnotes that would otherwise be required by GAAP.

        10.    Closing; Conditions to Obligations to Close.

               10.1 The closing of the transactions contemplated by this
Agreement (the "Closing") will take place at the offices of Morrison & Foerster
LLP, 755 Page Mill Road, Palo Alto, CA 94304, at 11:00 a.m., on the earliest

Informatica and each of its directors, officers, employees, affiliates, agents
and shareholders (the "Informatica Indemnitees") from and against:

inaccuracy of any representation, warranty, agreement or covenant of PwC set
forth in this Agreement (provided that for purposes of this Section 11, PwC's

               (a) Whenever any claim shall arise or any proceeding shall be
instituted involving any party entitled to indemnification under this Section 11
(the "Indemnified Party"), the Indemnified Party shall promptly notify in
writing the party from whom indemnification

hereunder is sought (the "Indemnifying Party"), including, when known, the facts
constituting the basis for such claim or proceeding and the amount or an
estimate of the amount of the indemnified liability arising therefrom. In
addition, each party hereto hereby agrees to provide to the other party written
notification and copies of communication from third parties received or made by
such parties relating to any matter subject to any indemnification hereunder.
Any failure by the Indemnified Party to timely furnish to the Indemnifying Party
any notice or copy required to be furnished under this Section 11.3 shall not
relieve any such Indemnifying Party from any liability that it may have to the
Indemnified Party under this Section 11 except to the extent that the
Indemnifying Party's ability to defend such claim is materially prejudiced by
the failure to give such notice or copies.

               (b) In connection with any claim giving rise to indemnity
hereunder arising out of any claim or legal proceeding brought by any person who
is not an Indemnified Party, the Indemnifying Party shall be entitled, upon
written notice to the Indemnified Party, to participate in the defense of such
action and to assume control of such defense; provided, however, that:

                      (i) the Indemnified Party shall be entitled to participate
in (but not control) the defense of such claim and to employ counsel at its own
expense to assist in the handling of such claim;

                      (ii) the Indemnifying Party shall obtain the prior written
approval of the Indemnified Party before entering into any settlement of such
claim or ceasing to defend against such claim, which approval shall not be
unreasonably withheld except that it shall not be unreasonable to withhold
approval if, pursuant to or as a result of such settlement or cessation,
injunctive or other equitable relief, or damages in excess of the limitations
set forth in Section 11.4 hereof, would be imposed against the Indemnified
Party;

                      (iii) the Indemnifying Party shall not consent to the
entry of any judgment or enter into any settlement that does not include as an
unconditional term thereof the giving by the claimant or plaintiff to each
Indemnified Party of a release from liability in respect of such claim; and

                      (iv) the Indemnifying Party shall not be entitled to
control, but shall be entitled to participate at its own expense in the defense
of, and the Indemnified Party shall be entitled to have sole control at its own
expense over, the defense or settlement of any claim to the extent the claim
seeks an order, injunction or other equitable relief against the Indemnified
Party which, if successful, could, in the sole judgment of the Indemnified
Party, materially interfere with the business, operations, assets, condition or
prospects of the Indemnified Party, provided, the Indemnified Party shall give
notice to the Indemnifying Party of such judgment and assumption of control as
provided in Section 11.3(c) hereof.

               (c) If the Indemnifying Party does not assume control of the
defense of such claims as provided in Section 11.3(b), the Indemnified Party
shall have the right to defend such claim in any manner as it may deem
appropriate at the cost and expense of the Indemnifying Party, and the
Indemnifying Party will promptly reimburse the Indemnified Party thereof in
accordance with this Section 11. The reimbursement of fees, costs and expenses
required by this Section 11 shall be made by periodic payments during the course
of the investigation or defense, as and when bills are received or expenses
incurred.

        11.4   Limitations.

               (a) Any other provision hereof to the contrary notwithstanding,
the maximum aggregate amount of indemnification which may be required of PwC or
Informatica under this Section 11 shall not exceed $15,000,000.

               (b) Any other provision hereof to the contrary notwithstanding,
neither PwC nor Informatica shall have any liability for indemnification
pursuant to this Section 11 unless and until the aggregate amount of the losses,
liabilities, damages, and costs actually incurred by the PwC Indemnitees or the
Informatica Indemnitees, as applicable exceeds $100,000, at which point the
applicable Indemnifying Party shall be responsible for all such losses,
liabilities, damages and costs.

               (c) Any other provision hereof to the contrary notwithstanding,
the parties agree that the representations and warranties of the parties
contained in this Agreement and in any certificates delivered pursuant to this
Agreement shall survive for a period of two years after the Closing Date,
regardless of any investigation made by either party prior to the date hereof or

        12.    Miscellaneous.

               12.1 Without the prior written consent of the other party, except
as permitted herein, neither party will disclose or reveal to any third person
any confidential, non-public or commercially valuable information ("Confidential
Information") concerning the other party or its business to which such party was
exposed in connection with this Agreement, other than to PwC's and Informatica's
respective subcontractors and to each other's employees on a need-to-know basis.
Each party shall use Confidential Information of the other party which is
disclosed to it only for the purposes of this Agreement. If disclosure of such
Confidential Information is required under provisions of any law or court order,
the party required to make the disclosure will notify the other party of the
obligation to make such disclosure sufficiently in advance of the disclosure
that such party will have a reasonable opportunity to object. Each party agrees
to take measures to protect the confidentiality of the other party's
Confidential Information that, in the aggregate, are no less protective than
those measures it uses to protect the confidentiality of its own Confidential
Information, but at a minimum, each party shall take reasonable steps to advise
their employees (and its subcontractors) of the confidential nature of the
Confidential Information and of the prohibitions on copying or revealing such
Confidential Information contained herein. PwC and Informatica each agree to
require that the other party's Confidential Information be kept in a reasonably
secure location. Neither party will be liable to the other for inadvertent or
accidental disclosure of Confidential Information if the disclosure occurs
notwithstanding the party's exercise of the same level of protection and care
that such party customarily uses in safeguarding its own confidential
information.

        Notwithstanding anything to the contrary contained in this Agreement,
neither party shall be obligated to treat as confidential, or otherwise be
subject to the restrictions on use, disclosure or treatment contained in this
Agreement for, any information disclosed by the other party (the "Disclosing
Party") which: (1) is rightfully known to the recipient prior to its disclosure
by the Disclosing Party; (2) is generally known or easily ascertainable by
non-parties of ordinary skill in computer or process design or programming or in
the business of Informatica; (3) is released by the Disclosing Party to any
other person, firm or entity (including governmental agencies or bureaus)
without restriction; (4) is independently developed by the recipient without any
reliance on the Disclosing Party's confidential information; or (5) is or later
becomes publicly available

conditions of this Agreement shall inure to the benefit of and be binding upon

of the Shares). This Agreement may not be assigned by either party without the
prior written consent of the other party; provided, however, PwC shall have the
right to assign its interest in this Agreement, including without limitations,
the licenses granted to PwC herein, without the written consent of Informatica,
to any successor in interest to the business unit of PwC primarily responsible
for the provision of services contemplated in Section 3 herein ("PwC
Successor"), and Informatica shall have the right to assign its interest in this
Agreement, including without limitations, the licenses granted to PwC herein,
without the written consent of PwC, to any successor in interest to
Informatica's business that utilizes the Transferred IP. Nothing in this
Agreement, express or implied, is intended to confer upon any party other than
the parties hereto or their respective successors and assigns any rights,
remedies, obligations or liabilities under or by reason of this Agreement,
except as expressly provided in this Agreement.

               12.3 This Agreement shall be governed by and construed under the
laws of the State of Delaware (excluding rules governing conflicts of laws).

               12.4 This Agreement may be executed in two or more counterparts,
each of which shall be deemed an original, but all of which together shall
constitute one and the same instrument.

               12.5 The titles and subtitles used in this Agreement are used for
convenience only and are not to be considered in construing or interpreting this
Agreement.

to have been duly given (a) when hand delivered to the other party; (b) when
