Microsoft under applicable law solely as a result of entering into this
Agreement (ii) are based solely upon the amounts payable under this Agreement,
and (iii) are required to be collected from Microsoft by Inktomi under
applicable law, provided, however, that solely with respect to sales tax or use
tax payable to those taxing jurisdictions that impose sales or use taxes under
applicable law upon the vendor, rather than the purchaser, clause (i) above
shall be modified to provide "sales taxes or use taxes that are owed by Inktomi
under applicable law solely as a result of entering into this Agreement and
clause (iii) shall be modified to provide "are permitted to be collected from
Microsoft by Inktomi under applicable law." (Such Taxes as are described in
clauses (i), (ii) and (iii) above, the "Invoiced Taxes"). The Invoiced Taxes
shall be stated separately as applicable on Inktomi's invoices and shall be
remitted by Microsoft to Inktomi. Inktomi shall promptly provide to Microsoft
official tax receipts indicating that such Invoiced Taxes have been collected by
Inktomi. Microsoft may provide to Inktomi an exemption certificate acceptable to
Inktomi and to the relevant taxing authority (including without limitation a
resale certificate) in which case Inktomi shall not collect the Taxes covered by
such certificate. Inktomi agrees to take such steps as are reasonably requested
by Microsoft to minimize such Invoiced Taxes in accordance with all relevant
laws and to reasonably cooperate with and assist Microsoft, at Microsoft's
request, in challenging the validity of any Invoiced Taxes or other Taxes paid
directly by Microsoft to the relevant taxing authority. Inktomi shall indemnify
and hold Microsoft harmless from any Taxes, penalties, interest, or additions to
tax arising from amounts paid by Microsoft to Inktomi under this Agreement that
are asserted or assessed against Microsoft to the extent such amounts are
related to Invoiced Taxes paid to Inktomi by Microsoft under this section. Other
than the Invoiced Taxes, all Inktomi Taxes shall be the responsibility of
Inktomi and may not be passed on to Microsoft. Inktomi takes full responsibility
for all such Inktomi Taxes, including penalties, interest and other additions
thereon and agrees to indemnify, defend and hold Microsoft harmless from any
claims, causes of action, costs (including without limitation, reasonable
attorneys' fees), penalties, interest charges and other liabilities of any
nature whatsoever associated therewith. All Taxes that are imposed on Microsoft
under applicable law (the "Microsoft Taxes") shall be the responsibility of
Microsoft and may not be passed on to Inktomi. Microsoft takes full
responsibility for all such Microsoft Taxes, including penalties, interest and
other additions thereon and agrees to indemnify, defend and hold Inktomi
harmless from any claims, causes of action, costs (including without limitation,
reasonable attorneys' fees), penalties, interest charges and other liabilities
of any nature whatsoever associated therewith.

               3.2.2  In the event that Taxes are required to be withheld on
payments made hereunder by any U.S. (state, local or federal) or foreign
government, Microsoft may deduct such Taxes from the amount owed Inktomi and pay
them to the appropriate taxing authority. Microsoft shall in turn promptly
secure and deliver to Inktomi an official receipt for any Taxes withheld.
Inktomi may provide to Microsoft an exemption certificate acceptable to
Microsoft and to the relevant taxing authority (including without limitation a
resale certificate) in which case Microsoft shall not collect the Taxes covered
by such certificate. Microsoft agrees to take such steps as are reasonably
requested by Inktomi to minimize such Taxes in accordance with all relevant 

                                       8


 
laws and to reasonably cooperate with and assist Inktomi, at Inktomi's request,
in challenging the validity of any such Taxes.

               3.2.3  Inktomi agrees and acknowledges that it will be
responsible for all of its federal and state taxes, withholding, social
security, unemployment and other related taxes, insurance, and other benefits,
and all salaries, benefits, and other costs of its employees.

          3.3  Microsoft agrees to keep, for not less than eighteen (18) months,
all proper records and books of account and all proper entries therein relating
to the calculations made under Section 2.  Inktomi may cause an audit to be
made, at its expense, of the applicable records in order to verify statements
rendered hereunder.  Any such audit shall be conducted only by a certified
public accountant (other than on a contingency-fee basis) and shall be conducted
during regular business hours at Microsoft's offices and in such a manner as not
to interfere with Microsoft's normal business activities.  In no event shall an
audit with respect to any royalty statement commence later than eighteen (18)
months from the date of the statement involved, nor shall the audits be made
hereunder more frequently than once annually, nor shall the records supporting
any statements be audited more than once.  Inktomi shall require the certified
public accountant when engaged to execute and deliver to Microsoft a certificate
in substantially the following form:

   "I hereby certify that I have been engaged by Inktomi to audit the books and
   records of MICROSOFT CORPORATION.  Inktomi will not pay me on a contingent-
   fee basis.  The fees to be received by me for conducting the audit shall be
   in no manner variable according to the findings or results of the audit.

Inktomi hereby agrees to make available to Microsoft, upon request, its records
and reports pertaining to the audit and any such records and reports prepared
for Inktomi by third parties (including the work sheets generated by its
auditors) but only in the event that Inktomi makes any claim with respect to
such audit.  If any Inktomi audit should determine that Microsoft underpaid
Inktomi by an amount of 5% or more for the period audited, then in addition to
any and all other rights and remedies Inktomi may have under the circumstances,
Inktomi may require Microsoft to reimburse it for all costs it incurred relating
to such audit in addition to paying the amount otherwise owed.

Inktomi is contemplating any modifications to the Inktomi Search Engine or
Coupled Cluster Technology which might materially affect the performance of the
Product, Inktomi will confer in good faith with Microsoft regarding the
appropriateness of such modifications and mutually agree whether or not to make
such modifications; provided, however, that such consultation will not be deemed
to relieve Inktomi from its obligations to ensure that the Product continues to
meet the Specifications and operational cost estimates as specified in Exhibit C
at all times during the Term.

               4.1.3  Prior to customization of the Inktomi Search Engine in
accordance with the Specifications, and thereafter throughout the Term, Inktomi
will keep Microsoft informed, in writing, of all planned enhancements to the
Inktomi Search Engine, and the status of development thereof, provided Inktomi
has the right to do so. Unless requested otherwise by Microsoft, Inktomi will
incorporate any or all such other planned enhancements into the Product,
provided Inktomi has the right to do so, in which case the Specifications shall
be deemed to be amended to include such enhancements.

               4.1.4  From time to time, Microsoft may request that Inktomi
undertake to develop certain enhancements to the Product. Upon such request,
Inktomi shall confer in good faith with Microsoft regarding the feasibility of
developing such enhancements and the time frame for developing, testing and
incorporating such enhancements (giving due consideration to the status of
Microsoft as a primary licensee of Inktomi). Then, Inktomi and Microsoft shall
mutually agree as to whether Inktomi should pursue development of such
enhancements, and, if so, which of Inktomi and/or Microsoft will fund such
development, and, if funded in substantial part by Microsoft, whether the

          4.2  Acceptance.  The terms and conditions contained in this Section
               ----------
4.2 will apply to the initial release of the Product, as well as to each
subsequent release, upgrade, enhancement and version thereof.

               4.2.1  Inktomi agrees to thoroughly test the Product (including
without limitation each and every release, version, and enhancement thereof), as
appropriate under the circumstances, at all appropriate stages of development,
and shall document its testing by written test documents delivered to Microsoft.
Inktomi will submit its test plans to Microsoft for review, so as to ensure that
Microsoft's standards of quality are maintained, and Inktomi agrees to
subsequently modify the test plans to accommodate Microsoft's requests if
Microsoft reasonably deems any changes to be necessary or appropriate. Such test
documents shall include a detailed description of the tests as conducted, and
test results (including, without limitation, resulting bug list and outstanding
issues list). Notwithstanding anything contained in this Agreement to the
contrary, Inktomi will not deploy the Product, and/or any enhancement thereof,
unless and until Microsoft authorizes such deployment in writing.

               4.2.2  If either party is aware or becomes aware of a delay that
will prevent Inktomi from meeting a scheduled milestone for any Deliverable
under the Schedule, such party will promptly inform the other party of such
delay, and the reason therefor, in writing. If such delay is caused by
Microsoft, the Schedule will automatically be deemed extended, for the
applicable Deliverable and for subsequent deliverables, if and to the extent
minimally necessitated by the original delay. If such delay is caused by
Inktomi, Inktomi will be given a reasonable period (up to thirty (30) days,
depending on the circumstances) to cure the unmet Deliverable Schedule. However,
Inktomi acknowledges that timely meeting the Schedule is of critical importance
under this Agreement, and that time is of the essence in curing a delayed
delivery.

               4.2.3  Microsoft shall evaluate the beta and final version of
each Deliverable and shall submit an acceptance or rejection to Inktomi within
ten (10) days after Microsoft's receipt of the engineering prototype and beta
versions and fifteen (15) calendar days after receipt of the final version of
the Deliverable. If Microsoft identifies Errors in any Deliverable prior to
acceptance, then Inktomi shall correct, at its sole expense, such Errors, and
use its best efforts to effect such correction within the applicable time
specified in Exhibit B.

               4.2.4  If Inktomi fails to deliver any Deliverable within the
dates specified in the Schedule (after application of the applicable reasonable
cure period) and if any Errors discovered during the acceptance process cannot
be eliminated in the correction period specified in the Specifications or
Exhibit B (whichever is applicable) then Microsoft may, at its option: (i)
extend the correction period; or (ii) suspend its performance until the problem
is corrected to Microsoft's reasonable satisfaction and/or, if the failure to
deliver or uncorrected Error is material, terminate this Agreement for cause
pursuant to Section 9.

                                       11


 
               4.2.5  Notwithstanding anything contained herein to the contrary,
Inktomi shall at all times hereunder be responsible for ensuring that the
Product meets all Specifications, and if any Error is discovered after
acceptance, Inktomi shall remain obligated to correct such Error in accordance
with the applicable timetable determined by Microsoft and Inktomi as set forth
in the Specifications or Exhibit B, or as otherwise may be mutually agreed under
the circumstances.

          4.3  Specific Enhancements.  Without limiting the foregoing, Inktomi
               ---------------------
and Microsoft acknowledge that at some time during the Term they contemplate the
following enhancements to the Product:

               (a)  [*] to the [*]. In this connection, as soon as practicable
following execution of this Agreement, Inktomi will undertake a study (using one
or more neutral, independent third party consultants the identity of whom will
be subject to Microsoft's reasonable prior approval) to determine the cost,
timing and other feasibility aspects [*]. Following completion of this
feasibility study, unless said mutually approved consultant(s) indicate(s) that
[*] is impossible or would require more than [*] ([*]) [*], Inktomi and
Microsoft will meet and mutually determine a timetable and milestones for
Inktomi to accomplish [*], with Inktomi using its commercially reasonable
efforts to complete the [*] by no later than [*].

               (b)  development of international versions of the Product, in any
and all languages desired by Microsoft, upon timetables and in accordance with
technical specifications as are mutually agreed by Microsoft and Inktomi from
time to time during the Term.

Unless otherwise agreed by the parties, Inktomi's Services hereunder will
include, without limitation, all development services required with respect to
[*]. However, with respect to the port, Microsoft will provide such [*]
(including the services of Microsoft's [*]) as may be reasonably available
to Microsoft and reasonably requested by Inktomi.

     5.   Scope of Rights.
          --------------- 

          5.1  Inktomi Technology.  Nothing contained in this Agreement will
               ------------------                                           
be deemed to transfer any ownership in the Inktomi Technology to Microsoft, and
insofar as Microsoft is concerned, Inktomi will own all rights in and to the
Inktomi Technology.

          5.2  Microsoft Technology.
               -------------------- 

               5.2.1  Microsoft hereby grants to Inktomi a non-exclusive license

any third party's use of, the Microsoft Technology portion of the Product
without Microsoft's prior written approval (which Microsoft may give or withhold
in its sole and absolute discretion, and which may be conditioned, without
limitation, upon a royalty or other fee being payable to Microsoft).

               5.2.2   Subject to Section 5.2.1 above, as between Microsoft and
Inktomi, Microsoft will own all rights in and to Microsoft Technology.

          5.3  Derivative Technology.
               --------------------- 

               5.3.1   Inktomi Derivative Technology will be owned exclusively
by Inktomi and treated in the same manner as Inktomi Technology under this

                       (a)  Inktomi will not make available any Inktomi
Derivative Technology or any search engine features implemented thereby to any
third party search engine customer for a period of not less than [*] ([*]) years
commencing on the incorporation of the final (not "beta") version of the Inktomi
Derivative Technology into the Microsoft Search Engine. After the expiration of
said [*] ([*]) year exclusivity period, Inktomi will have the right to use the
Inktomi Derivative Technology in other versions of the Inktomi Search Engine,
but if Inktomi so uses any Inktomi Derivative Technology it will pay to
Microsoft, in [*], an amount equal to [*] of the amounts Microsoft paid for
development of such Inktomi Derivative Technology pursuant to Section 2.1.1
above, but except for such payments Inktomi will not owe any royalties or other
amounts to Microsoft for any use of the Inktomi Derivative Technology; and

                       (b)  Inktomi hereby grants to Microsoft a non-exclusive
and irrevocable, fully paid-up, license under any and all patents that Inktomi
may own related to any portion of the Inktomi Derivative Technology, throughout
the Territory for the applicable life of the respective patent; provided,
however, that nothing contained in this clause (b) shall be deemed to require
Inktomi to deliver any code to Microsoft.

               5.3.2   Each of Inktomi and Microsoft will own an [*] ([*])
interest in and to all Joint Derivative Technology, at all stages of
development, and the parties hereby assign to each other such individual rights
therein as necessary to effectuate said [*] ownership relationship. Subject to
the other rest of this Section 5.3.2, each party shall have the right to use
Joint Derivative Technology as each may determine (including creating other
derivative works based thereon) without any limitation or necessity to account
to the other. However, Inktomi will not make available any Joint Derivative
Technology or any search engine features implemented thereby to any third party
search engine customer for a period of not less than [*] ([*]) years commencing
on the incorporation of the final (not "beta") version of the Joint Derivative
Technology into the Microsoft Search Engine. After the expiration of said [*]
([*]) year exclusivity period, Inktomi will have the right to use the Joint
Derivative Technology in other versions of the Inktomi Search Engine, but if
Inktomi so uses any Joint Derivative

Technology it will pay to Microsoft, in [*], an amount equal to [*] of the
amounts Microsoft paid for development of such Joint Derivative Technology
pursuant to Section 2.1.1 above, but except for such payments by Inktomi to
Microsoft, and the payments by Microsoft to Inktomi pursuant to Section 2.1.2
above, neither Microsoft nor Inktomi will owe any royalties or other amounts to
the other for any of their respective uses of the Joint Derivative Technology.
Each party will have the right to file registrations, and prosecute
infringements, relating to the Joint Derivative Technology, but will consult
with the other party before doing so, and will cooperate with the other should
it desire joint filings or prosecutions.

               5.3.3   Subject to Section 5.3.4 below, as between Microsoft and
Inktomi, Microsoft will own all rights in and to the Microsoft Derivative
Technology.

          (a)  Inktomi acknowledges and agrees that, insofar as Inktomi is
     concerned, the Microsoft Derivative Technology has been specially ordered
     and commissioned by Microsoft and are "works made for hire" for copyright
     purposes, with all copyrights in the Microsoft Derivative Technology owned
     by Microsoft.

          (b)  To the extent (if any) that any Microsoft Derivative Technology
     does not qualify as a work made for hire under applicable law, and to the
     extent that the Microsoft Derivative Technology includes material subject
     to copyright, patent, trade secret, or other proprietary right protection,
     Inktomi hereby assigns to Microsoft, its successors and assigns, all right,
     title and interest in and to the Microsoft Derivative Technology,
     including, but not limited to, all rights in and to any inventions and
     designs embodied in the Microsoft Derivative Technology or developed in the
     course of Inktomi's creation of the Microsoft Derivative Technology. The
     foregoing assignment includes a license under any current and future
     patents owned or licensable by Inktomi to the extent necessary to combine
     the Microsoft Derivative Technology with any hardware and software.

          (c)  Inktomi hereby irrevocably transfers and assigns to Microsoft any
     and all "moral rights" that Inktomi may have in the Microsoft Derivative
     Technology.  Inktomi also hereby forever waives and agrees never to assert
     any and all "moral rights" it may have in the Microsoft Derivative
     Technology, even after termination of the Services.

               5.3.4   Microsoft hereby grants to Inktomi a non-exclusive
license to incorporate Microsoft Derivative Technology into the Product, as
contemplated by the development process hereunder, provided that Inktomi may not
itself use, nor authorize any third party's use of, the Microsoft Derivative
Technology portion of the Product without Microsoft's prior written approval
(which Microsoft may give or withhold in its sole and absolute discretion, and
which may be conditioned, without limitation, upon a royalty or other fee being
payable to Microsoft).

party hereby appoints and constitutes the requesting party as its attorney-in-
fact to execute, acknowledge and file all such instruments and to take such
other steps in its name as the requesting party, in its reasonable judgment, may
deem necessary or desirable to secure and/or protect its rights, such
appointment being a right coupled with an interest and irrevocable.

any aspect of Inktomi's relationship with Microsoft, or (ii) otherwise deprecate
Microsoft technology.

          10.3  Neither party will issue any press release or make any public
announcement(s) relating in any way whatsoever to this Agreement or the
relationship established by this Agreement without the express prior written
consent of the other party. However, the parties acknowledge that this
Agreement, or portions thereof, may be required under applicable law to be
disclosed, as part of or an exhibit to a party's required public disclosure
documents. If either party is advised by its legal counsel that such disclosure
is required, it will notify the other in writing and the parties will jointly
seek confidential treatment of this Agreement to the maximum extent reasonably
possible, in documents approved by both parties and filed with the applicable
governmental or regulatory authorities. Notwithstanding the foregoing, Microsoft
and Inktomi will cooperate to create a mutually approved joint press release
regarding the non-confidential aspects of this Agreement, which press release
shall be issued by each party on the Launch Date; provided, however, that the
precise timing of such press release shall be subject to the approval of
Microsoft (in its sole and absolute discretion).

     11.  Technology Escrow.
          ----------------- 

          11.1  To ensure that Microsoft will have access to such technology as
may be necessary or appropriate to permit it to use the Product to generate
search results (and to develop enhancements and other derivative works for use
in connection with the Product) as contemplated by this Agreement and the
Ancillary Agreements, Inktomi agrees to provide to an escrow agent, the identity
of which is satisfactory to Inktomi and Microsoft, a copy of all source code,
binary code and related documentation used in, or in connection with the
development of, the Product or the Deliverables (including all related
enhancements), concurrently with the deployment or delivery of the applicable
Deliverable or Product (including all related enhancements) to Microsoft.
Without limiting the generality of the foregoing, all source code, binary code
and documentation for the Inktomi's Search Engine and relevant Coupled Cluster
Technology will be 

                                       20


 
escrowed hereunder. Said escrow agent will hold such code and documentation in
escrow, and release it if and only if it is permitted to do so pursuant to the
terms and conditions of the Escrow Agreement appended hereto as Schedule I. The
parties shall execute an Escrow Agreement substantially in the form of Schedule
I concurrently with the execution of this Agreement.

          11.2  If Microsoft is entitled to receive any source code, binary code
and/or documentation pursuant to said Escrow Agreement, (i) Inktomi will be
deemed to automatically have granted to Microsoft a non-exclusive and
irrevocable license during the remainder of the Term and throughout the
Territory to use the Product (and all required underlying Inktomi Technology)
solely to generate search results (and to create enhancements and derivative
works for use in connection with the Product) as contemplated by this Agreement
and the Ancillary Agreements, and (ii) Inktomi agrees to furnish to Microsoft,
upon Microsoft's request, the services of Inktomi personnel familiar with the
structure and operation of such source code and/or binary code to explain such
code and train Microsoft personnel in its operation. Such services shall
continue for so long as is reasonably required by Microsoft personnel to become
proficient in its use and application, and Inktomi will charge Microsoft only
for its direct, actual, out-of-pocket costs of such services.

     12.  Miscellany.
          ---------- 

          12.1  Neither party shall represent itself as the agent or legal
representative of the other for any purpose whatsoever, and neither party shall
have the right to create or assume for the other any obligation of any kind.
This Agreement shall not create or be deemed to create an agency, partnership,
franchise, employment relationship or joint venture between the parties. Each
party's employees who perform services related to this Agreement shall remain
under the exclusive direction and control of their respective employer and shall
receive such salaries, compensation and benefits as their respective employer
may from time to time determines. Each party shall have full and sole
responsibility for its employees who perform any service related to this
Agreement with regard to compliance with all applicable laws, rules and
regulations governing such party relating to employment, labor, wages, benefits,
taxes and other matters affecting its employees.

          12.2  Any notice required or permitted to be given under this
Agreement shall be made in writing and shall be deemed to have been given or
made if it is in writing and is: (i) delivered in person, (ii) sent by same day
or overnight courier, (iii) mailed by certified or registered mail, return
receipt requested, postage prepaid, addressed to the party at its address set
forth below or at such other address as such party may subsequently furnish to
the other party by notice hereunder, or (iv) delivered by facsimile, the
transmittal of which shall be confirmed by a telephone call to the other party
and by dispatch of a confirming copy of the transmittal by registered or
certified mail, postage prepaid. Notices will be deemed effective on the date of
delivery in the case of personal delivery, or three (3) business days after
mailing, or on the date of dispatch in the case of notification by facsimile
(assuming confirmation of transmission). 

                                       21


 
The parties' addresses for purposes of notice shall be as set forth above,
provided that all notices to Inktomi shall be sent to the attention of General
Counsel; and all notices to Microsoft shall be sent to the attention of Shirish
Nadkarni, with a copy to: Law & Corporate Affairs, U.S. Legal.

          12.3  This Agreement shall be construed, enforced, performed and in
all respects governed by and in accordance with the laws in the State of
Washington. In any action or suit to enforce any right or remedy under this
Agreement the prevailing party shall be entitled to recover its reasonable
attorneys' fees and costs.

          12.4  In the event any provision of this Agreement is rendered null,
void or otherwise ineffective in any given country or any political subdivision
in a given country, then (i) the parties agree to negotiate in good faith an
acceptable alternative provision which reflects as closely as possible the
intent of the unenforceable provision and which shall apply only with respect to
that portion of the Territory in which the original provision is rendered null,
void or otherwise ineffective and (ii) notwithstanding, and regardless of
whether the parties reach agreement after the good faith negotiations described
in clause (i) immediately above, the validity, legality and enforceability of
the remaining provisions of this Agreement with respect to such portion of the
Territory (and of all of the provisions of this Agreement with respect to the
balance of the Territory) shall not in any way be affected or impaired thereby
and shall remain in full force and effect. Section and all other headings used
herein are provided for convenience only and are not to be given any legal
effect or considered in interpreting any provision of this Agreement. No
provision of this Agreement shall be interpreted against any party because such
party or its legal representative drafted such provision.

          12.5  Except as expressly permitted hereunder or in Exhibit D hereto,
neither party may transfer, assign or sublicense this Agreement, or any rights
or obligations hereunder, whether by contract or by operation of law, except
with the express written consent of the other party, and any attempted transfer,
assignment or sublicense by a party in violation of this Section shall be void.
For purposes of this Agreement, an "transfer" under this Section shall be deemed
to include, without limitation, the following: (a) a merger or any other
combination of an entity with another party (other than a reincorporation of
Inktomi from the State of California to the State of Delaware), whether or not
the entity is the surviving entity; (b) any transaction or series of
transactions whereby a third party acquires direct or indirect power to control
the management and policies of an entity, whether through the acquisition of
voting securities, by contract, or otherwise; (c) in the case of Inktomi, the
sale or other transfer of Inktomi's search engine business or any other
substantial portion of Inktomi's assets (whether in a single transaction or
series of transactions), or (d) the transfer of any rights or obligations in the
course of a liquidation or other similar reorganization of an entity (other than
a reincorporation of Inktomi from the State of California to the State of
Delaware). Neither party will unreasonably withhold or delay its consent to a
requested transfer, assignment or sublicense. Subject to the provisions of this
Section, this Agreement shall be binding upon and inure to the benefit of each
party and their respective successors and assigns.

                                       22


 
          12.6   All rights and obligations of the parties hereunder are
personal to them. Except as otherwise specifically stated herein, this Agreement
is not intended to benefit, nor shall it be deemed to give rise to, any rights
in any third party.

          12.7   Each party shall be responsible for compliance with all
applicable laws, rules and regulations, if any, related to the performance of
its obligations under this Agreement.


          12.8   No waiver of any breach of any provision of this Agreement
shall constitute a waiver of any prior, concurrent or subsequent breach of the
same or any other provisions hereof or thereof, and no waiver shall be effective
unless made in writing and signed by an authorized representative of the waiving
party.

          12.9   Neither party shall be liable hereunder by reason of any
failure or delay in the performance of its obligations hereunder during any
event of force majeure.

          12.10  This Agreement, along with the Ancillary Agreements, together
contain the entire agreement of the parties with respect to the premises, and
may not be modified or amended except by a written instrument executed by the
party sought to be charged or bound thereby.

          12.11  The parties acknowledge that there may be instances during the
Term when, notwithstanding the Non-Disclosure Agreement referred to in Section
10.1 above, Inktomi will not wish to disclose or have Microsoft become aware
(through inspection or otherwise) of certain confidential and proprietary
information of Inktomi relating to its business and/or technology. In those
instances, the parties agree to work together in a spirit of cooperation to work
around such disclosure so that Inktomi is able to perform the Services to
Microsoft's reasonable satisfaction and otherwise discharge its obligations
under this Agreement without making such disclosure.

          12.12  Inktomi will notify Microsoft of all meetings of Inktomi's
Board of Directors (and all meetings of any executive committee of such Board),
with such notice being given at the same time and in the same manner as Inktomi
notifies the members of such Board (or executive committee, if applicable).
Microsoft shall have the right to designate one individual to attend (at
Microsoft's sole expense) each such meeting in a non-voting, observer capacity,
and in this connection, Inktomi will provide to such individual copies of all
information packages, slides and other review and/or presentation materials (if
any) made available to members of such Board relating to Inktomi's search engine
business; provided, however, that Inktomi shall have the right without prior
written notice to exclude the Microsoft representative from any part of the
discussion (and/or refrain from delivering copies of materials) if the Board
determines in good faith that the material to be discussed is privileged or of
such a sensitive nature that such representative should not be present. In
addition, Inktomi shall provide such representative with copies of all written
materials supplied by Inktomi to potential third party investors during the
Term. All information learned by the representative by

                                       23


 
attending such meeting and all written materials delivered to the representative
shall be treated as Confidential Information in accordance with the Non-
Disclosure Agreement.
 
          13.  Insurance.
               --------- 

               13.1   Throughout the term of this Agreement, Inktomi shall
procure and maintain insurance coverage. Such insurance shall be in a form and
with insurers reasonably acceptable to Microsoft, and shall comply with the
following minimum requirements:

                      (i)    [*] Liability insurance with policy limits of not
less than [*] Dollars (US$[*]) [*] each occurrence for [*] and [*] combined.
Such policy shall be the [*] including coverage for [*].

                      (ii)   [*] Liability Insurance with policy limits of not
less than [*] (US$[*]) each claim with a [*] of not more than [*] Dollars
(US$[*]). Such insurance shall include coverage for [*] (other than [*]) of [*]
[*] including without limitation [*] and [*] as related to Inktomi's performance
under this Agreement.

                      (iii)  [*]. Inktomi shall at all times comply with all
applicable workers' compensation, occupational disease, and occupational health
and safety laws, statutes, and regulations to the full extent applicable. Such
workers' compensation and occupational disease requirements shall include
coverage for all employees of Inktomi, and for all [*] by Inktomi, [*]
(including [*]) by [*] which arises out of or in connection with the performance
of this Agreement by Inktomi. Satisfaction of these requirements shall include,
but shall not be limited to:

                      a.     full participation in any required governmental
     occupational injury and/or disease insurance program, to the extent
     participation in such program is mandatory in any jurisdiction, and

                      b.     purchase of [*] and [*] insurance providing
     benefits to employees in full compliance with all applicable laws,
     statutes, and regulations (but only to the extent such coverage is not
     provided under a mandatory government program as in a. above), and/or

                      c.     maintenance of a legally permitted and
     governmentally approved program of self insurance for [*] and [*].

                                       24

[*]=CERTAIN INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND FILED SEPARATELY 
WITH THE COMMISSION. CONFIDENTIAL TREATMENT HAS BEEN REQUESTED WITH RESPECT TO 
THE OMITTED PORTIONS.


 
Except to the extent prohibited by law, the program of Inktomi's compliance with
[*] laws, statutes, and regulations in a., b., or c. above shall provide for a
full waiver of rights of subrogation against Microsoft, its directors, officers,
and employees. If Inktomi, or any subcontractor retained by Inktomi, fails to
effect and maintain a program of compliance with applicable [*] laws, statutes,
and regulations, and Microsoft incurs liability or fines or is required by law
to provide benefits to such employees, or to obtain coverage for such employees,
Inktomi shall indemnify Microsoft for such fines, payment of benefits to Inktomi
or subcontractor employees or their heirs or legal representatives, and/or the
cost of effecting coverage on behalf of such employees. Any amount owed to
Microsoft by Inktomi pursuant to this indemnity may be deducted from any
payments owed by Microsoft to Inktomi for performance of this Agreement.

               13.2   Promptly following execution of this Agreement, Inktomi
shall provide to Microsoft proof evidencing full compliance with the insurance
requirements set forth herein. Inktomi shall notify Microsoft in writing at
least fifteen (15) days in advance if Inktomi's insurance coverage is to be
canceled or materially altered so as not to comply with the requirements of this
section. In the event Inktomi fails to provide such proof or fails to provide
such notice as requested herein, and in the event of liability or expense
incurred by Microsoft as a result of such failure by Inktomi, Inktomi hereby
agrees to indemnify Microsoft for all liability and expense (including
reasonable attorneys' fees and expenses associated with establishing the right
to indemnity) incurred by Microsoft as a result of such failure by Inktomi.

               13.3   Inktomi agrees that Microsoft will not be responsible for
loss of or damage to any personal property located on Microsoft premises
belonging to Inktomi or any subcontractor retained by Inktomi. This Section 13.3
will not apply to the moved Hosting Servers (as defined in the Software Hosting
Agreement of even date herewith) if Microsoft exercises its right to require
Inktomi to move the Hosting Servers pursuant to Section 2.6.2 of said Software
Hosting Agreement.

               13.4   Upon termination of this Agreement, Inktomi will maintain
an extended reporting period providing that the claims first made and reported
to the insurance company within one year after the end of this Agreement will be
deemed to have been made during the applicable policy period.

1.   OVERVIEW
================================================================================

The goal of this document is to provide a reasonably complete list of Yukon
requirements for the Inktomi search service.  Note that a number of the
requirements in this document are met by the existing search service but are
included anyway for the sake of completeness.

The Section 2 lists all requirements according to area (Performance and
Scalability, Reliability and Fault Tolerance, ...) together with information on
Target Release and Due Date as defined below. The Appendix (Section 7) follows a
similar organization and provides more detail on the requirements..

EXHIBIT D --------- Transfer of Control by Inktomi ------------------------------ If Inktomi requests Microsoft's consent to a transfer as described in clause (a) of Section 12.5 of this Software Development Agreement to which this Exhibit D is appended, and Microsoft reasonably withholds its consent to such transfer (an "Unconsented Transfer"), then Inktomi will nevertheless have the right to transfer this Agreement in connection with its proposed Unconsented Transfer subject to the following conditions precedent to the Unconsented Transfer: (i) Inktomi, at its sole cost and expense, and without any financing supplied by Microsoft, will create a separate cluster of Hosting Servers for Microsoft required to service Microsoft's reasonably anticipated needs for a period of twelve months after the commencement of operation of such new and relocated cluster (provided however that Microsoft will purchase, or fund (in accordance with the Loan Agreement of even date herewith) Inktomi's purchase of, (whichever Microsoft elects) any new hosting servers beyond the Hosting Servers purchased by Inktomi under the Software Hosting Agreement of even date herewith necessary to service Microsoft's reasonably anticipated needs as set forth above); (ii) Inktomi will relocate, at its sole cost and expense (including, without limitation, indemnifying Microsoft and holding it harmless against any and all Taxes that arise as a direct or indirect result of the relocation of the Hosting Servers), all Hosting Servers referred to in clause (i) to a location designated by Microsoft, in its sole discretion; (iii) Inktomi, at its sole cost and expense, will provide training to Microsoft personnel to the extent requested by Microsoft, to enable such personnel to use and maintain the Microsoft Search Engine, and to create enhancements thereto, with reasonable competence (all as determined by Microsoft in its sole discretion); (iv) Inktomi will grant to Microsoft an irrevocable, non-exclusive, royalty- free license to use the Product (and all required underlying Inktomi Technology) solely in connection with Microsoft's operation of the Microsoft Search Engine (which license shall include the right to create enhancements and other derivative works based thereon for use in conjunction therewith) for such period as Microsoft may require to transition its search engine services to non-Inktomi technology (the "Transition Period"), and Inktomi will waive all royalties otherwise payable pursuant to this Software Development Agreement and/or the Information Services Agreement of even date herewith; for the purposes of this clause (iv), the Transition Period will commence at such time as Microsoft assumes control over said separate cluster and begins itself operating the Microsoft Search Engine, and will continue thereafter for eighteen months (18) or until the termination of said Software Development Agreement and Information Services Agreement (whichever is longer); 30 (v) Inktomi will direct the Escrow Agent to release to Microsoft all Confidential Materials held by the Escrow Agent, subject to Microsoft's agreement to use such Confidential Materials only in connection with its licensed rights under clause (iv) above; (vi) Inktomi will agree to reimburse Microsoft for all reasonable costs incurred by Microsoft in transitioning its search engine to non-Inktomi technology (whether created by Microsoft or by a third party); and (vii) Inktomi will cause the applicable proposed transferee of this Agreement to assume, jointly and severally with Inktomi, all of Inktomi's obligations hereunder. Microsoft will cooperate with Inktomi and use its reasonable best efforts so as to enable Inktomi to satisfy the foregoing conditions precedent in a timely manner. Upon satisfaction of the foregoing conditions precedent, said Software Hosting Agreement shall be deemed terminated pursuant to Section 10.1 thereof. Upon expiration of the Transition Period, all rights granted to Microsoft to use the Product (other than Microsoft Technology, Joint Derivative Technology and the Microsoft Derivative Technology) and/or any Inktomi Technology under the transitional license referred to in clause (iv) or otherwise shall cease, and Microsoft shall immediately return to Inktomi all Confidential Materials (and all copies thereof), provided however that, notwithstanding any provision of the Ancillary Agreements to the contrary, the undertaking by Inktomi to indemnify Microsoft and hold it harmless against Taxes as provided in clause (ii) above shall survive any such terminations. 31 SCHEDULE I ---------- ESCROW AGREEMENT THIS ESCROW AGREEMENT is entered into this ___ day of __________, 1997 by and among INKTOMI CORPORATION ("Inktomi"), a California corporation, whose address is 1900 South Norfolk Street, Suite 110, San Mateo, California 94403, DATA BASE, INC. ("Escrow Agent"), a Washington corporation, whose address is 307 South 140th Street, Seattle, WA 98168, and MICROSOFT CORPORATION ("Microsoft"), a Washington corporation whose address is One Microsoft Way, Redmond, WA 98052- 6399. A. Inktomi is the owner of computer programs and supporting documentation that contain confidential information and are protected under copyright and as trade secrets. Inktomi authorizes others to use the computer programs and documentation under writtenagreements which, among other things, require the other party to protect the confidentiality of Inktomi's property. B. Computer programs can be expressed in machine-readable form, called binary code, and in human-readable form, called source code or source listings. Generally, parties are unable to modify or correct errors in the binary code without having the source code. C. This escrow arrangement is provided to assure Microsoft of access to the source code, binary code and confidential supporting documentation in the event that Inktomi (i) discontinues all or substantially all of its search engine business operations or (ii) ceases to provide software development, error correction, product enhancements and upgrades, and regular maintenance of the computer programs (collectively, "Support") under and in accordance with the Software Development Agreement and/or the Information Services Agreement (the "Agreements") between Inktomi and Microsoft of even date herewith (as it may be amended by mutual agreement of Inktomi and Microsoft from time to time). THEREFORE, in consideration of the mutual covenants set forth in this Agreement, Inktomi, Microsoft and Escrow Agent agree as follows: 1. Confidential Materials. ---------------------- 1.1 Escrow Agent, as escrow agent, agrees to accept from Inktomi, for storage purposes only, confidential materials in the form of source code and binary code, program listings, supporting documentation, and other related materials for certain computer programs owned by Inktomi (collectively, "Confidential Materials"). Inktomi will furnish to Escrow Agent a list naming or describing all computer programs for which Confidential Materials are deposited into escrow. This list shall be certified by Inktomi as complete and accurate. A list of computer programs for which Confidential Materials are currently on deposit with Escrow Agent is attached as Exhibit A to this Agreement. This list will be supplemented and updated by Inktomi with each future deposit or withdrawal of Confidential Materials. For each deposit, Escrow Agent will issue receipts to Inktomi. 1.2 Upon each deposit of Confidential Materials, Inktomi shall furnish to Microsoft a copy of the list provided to Escrow Agent pursuant to this Section 1. Such list shall constitute notice to Microsoft that the Confidential Materials listed thereon have been deposited with Escrow Agent. Upon the request of Microsoft, Escrow Agent shall supply to Microsoft copies of all lists furnished by Inktomi to Escrow Agent hereunder. Escrow Agent shall not be required to determine the accuracy or completeness of the list(s) furnished by Inktomi hereunder, nor shall Escrow Agent be responsible for Confidential Materials not actually deposited with it, whether or not such Confidential Materials were required to be deposited under the terms of this Agreement, any license agreement between Inktomi and Microsoft or any other agreement. 2. Retention of Confidential Materials. Escrow Agent agrees to hold in ----------------------------------- safekeeping the Confidential Materials deposited hereunder, and shall release or disclose any or all such Confidential Materials only in accordance with the terms of this Agreement. 3. Release of Confidential Materials. Inktomi authorizes Escrow Agent to --------------------------------- release Confidential Materials only as follows: (a) Escrow Agent shall release to Inktomi all Confidential Materials requested by written demand of both Inktomi and Microsoft, provided that such Confidential Materials are specifically identified to the satisfaction of Escrow Agent, and provided that all fees payable to Escrow Agent for performance of its services hereunder have been fully paid. (b) Provided that all fees payable to Escrow Agent for the performance of its services hereunder have been fully paid, all Confidential Materials shall be returned to Inktomi at any time that Escrow Agent ceases doing business or is unable to hold the same in accordance with the terms of this Agreement due to forces beyond its reasonable control; provided however, that Escrow Agent gives such advance notice to Inktomi and Microsoft as is reasonably practicable, but in no event less than thirty (30) days. (c) In the event of (1) a demand by Microsoft pursuant to Subsection 4.1 hereof which is not disputed by Inktomi in the manner and within the time prescribed in Subsection 4.2 hereof, or (2) a determination by the panel of arbitrators in accordance with Section 5 hereof that (A) the applicable Agreement remains in force and effect and (B) Inktomi has discontinued all or substantially all of its search engine business operations or has ceased to Support the Confidential Materials on a timely basis as required under the terms of the applicable Agreement, then Escrow Agent shall, upon the receipt from Microsoft of full payment for the costs and expenses of duplication, make duplicate copies of those Confidential Materials which relate to the computer program or programs with respect to which demand is made and shall deliver such duplicate copies to Microsoft. Escrow Agent agrees that the "Write-Protect Ring" on magnetic tape reels furnished to Escrow Agent by Inktomi shall not be removed at any time. (d) Escrow Agent shall release such Confidential Materials to such persons and in such manner as shall be directed by order of any court of competent jurisdiction pursuant to -2- Section 6 or otherwise. Escrow Agent may also release Confidential Materials pursuant to the provisions of Section 11 below. 4. Demand and Dispute. ------------------ 4.1 In the event Microsoft desires release of Confidential Materials relating to one or more computer programs, Microsoft shall make written demand on Escrow Agent therefor, specifically designating the computer program or programs for which Confidential Materials are requested. Such demand must be accompanied by all of the following documents and certificates, each executed under oath by an authorized officer or representative of Microsoft: (a) A certified true copy of a notice that Microsoft has mailed to Inktomi at the address stated in this Agreement. The notice must contain a statement that Microsoft has determined that Inktomi has discontinued all or substantially all of its search engine business operations or has ceased to Support the Confidential Materials on a timely basis as required under the terms of the Agreements. (b) A certificate stating that (i) Microsoft mailed to Inktomi, registered or certified mail, the notice described in Paragraph 4.1(a) above, and that ten (10) business days have elapsed from such mailing without response from Inktomi, and (ii) before mailing the notice, Microsoft made a request upon Inktomi for support services and Microsoft did not receive a response to such request or received a response to the effect that Inktomi was unable or unwilling to provide such services or Inktomi in fact did not timely provide such services. (c) A copy of each of the Agreements, as executed by Inktomi and such Microsoft, together with a statement by Microsoft, certified by Microsoft, that the copies of the Agreements are true copies, and that the applicable Agreement(s) is(are) still in force and grants Microsoft the rights to use the computer program or programs for which Confidential Materials are requested. (d) A certificate stating that Microsoft will pay in advance for all expenses and costs of copying the Confidential Materials requested. (e) A Confidentiality and Use Limitation Certificate, in the form of Exhibit B attached hereto, for the benefit of Escrow Agent, Inktomi and any successor of either. (f) A certificate stating that Microsoft shall indemnify and hold harmless Escrow Agent from and against any and all losses, damages, and expenses (including attorney's fees) that may be incurred by Microsoft and/or Escrow Agent by reason of Escrow Agent's compliance in good faith with the terms of this Agreement. 4.2 Upon receipt of a demand and all required supporting documents described in Subsection 4.1 hereof, Escrow Agent shall promptly give notice to Inktomi of such receipt and transmit with such notice a copy of such demand and all accompanying documents. Inktomi or its successor may dispute such demand, at any time within ten (10) business days following -3- Escrow Agent's notice to Inktomi hereunder by (i) giving written notice to Escrow Agent that it continues to conduct all or substantially all of its search engine business operations and continues to Support the Confidential Materials on a timely basis as required under the terms of the Agreements, or (ii) otherwise specifically denying any statements made by Microsoft in one or more of the documents described in Paragraphs 4.1(a), (b) or (c) hereof. Such notice shall be accompanied by a certificate to Escrow Agent stating that Inktomi will submit to arbitration under the terms and conditions described in Section 5 hereof and abide by any decision rendered by the arbitrators in connection therewith. 4.3 Upon receipt of Inktomi's notice of dispute as provided in Subsection 4.2 hereof, Escrow Agent shall promptly give notice to Microsoft of such receipt and transmit with such notice a copy of such documents received from Inktomi relating to such dispute. Subject to the last sentence of this Subsection 4.3, Microsoft shall, within thirty (30) days following receipt of Inktomi's notice of dispute, furnish Escrow Agent with a certificate stating that Microsoft will submit to Arbitration under the terms and conditions described in Section 5 hereof and abide by any decision rendered by the arbitrators in connection therewith. Microsoft may withdraw its demand for release of the Confidential Materials at any time by giving Escrow Agent and Inktomi written notice of such withdrawal. 5. Arbitration. Upon the earlier of the expiration of the thirty (30) day ----------- period described in Subsection 4.3 or the receipt by Escrow Agent of Microsoft's certificate described in Subsection 4.3, the matter shall be submitted to arbitration proceedings in Seattle, Washington, which proceedings shall be conducted under the commercial rules then prevailing of the American Arbitration Association, by a panel of not less than three professional experts in the field of computer software technology. Each party will choose one arbitrator and the two arbitrators so chosen will choose a third. If the two designated arbitrators do not so choose a third within thirty (30) days, either party may apply to the local Superior Court to appoint a third arbitrator. The sole issue for arbitration shall be whether the Agreements remain in force and effect and whether Inktomi has discontinued all or substantially all of its search engine business operations or has ceased to Support the Confidential Materials on a timely basis as required under the terms of either or both of the Agreements. If the arbitrators determine that Inktomi has discontinued all or substantially all of its search engine business operations or has ceased to Support the Confidential Materials on a timely basis, the arbitrators shall order the release of Confidential Materials. The prevailing party in the arbitration proceedings shall be awarded reasonable attorneys' fees, expert and non-expert witness costs and expenses, and all other costs and expenses incurred directly or indirectly in connection with the proceedings, unless the arbitrators for good cause determine otherwise. The decision of the arbitrators shall be final and binding on the Inktomi and Microsoft and may be entered and enforced in any court of competent jurisdiction. 6. Interpleader. Notwithstanding any other provisions of this Agreement, if ------------ Escrow Agent receives a written demand from Microsoft for release of Confidential Materials and Escrow Agent is uncertain whether Inktomi's exercise of its right to dispute such demand pursuant to Subsection 4.2 hereof was timely or otherwise effective, then Escrow Agent may, in its sole discretion, begin an interpleader action, pursuant to applicable law, and deposit the Confidential -4- Materials with the clerk of the court or withhold release of the Confidential Materials until instructed otherwise by the court order. 7. Fees. Microsoft shall pay to Escrow Agent, in advance, fees at the standard ---- rate prescribed from time to time by Escrow Agent for performance of services hereunder. Prices will be revised annually in accordance with Escrow Agent's regular schedule of fees. 8. No Duty to Inquire into Truth, Authenticity or Authority; Right to Require -------------------------------------------------------------------------- Additional Documents. Escrow Agent shall not be required to inquire into the -------------------- truth of any statements or representatives contained in any notices, certificates or other documents required or otherwise provided hereunder, and shall be entitled to assume that the signatures on such documents are genuine, that the persons signing on behalf of any party thereto are duly authorized to execute the same, and that all actions necessary to render any such documents binding on the party purportedly executing the same have been duly undertaken. Without in any way limiting the foregoing, Escrow Agent may in its discretion require from Inktomi or Microsoft additional documents which it deems to be necessary or desirable in the course of performing its obligations hereunder. 9. Waiver of Claims. ---------------- (a) Inktomi hereby waives any claim for damages or otherwise which it may have against Escrow Agent for any acts undertaken by Escrow Agent pursuant to Microsoft's direction in Escrow Agent's good faith compliance with the terms of this Agreement. (b) Microsoft hereby waives any claim for damages or otherwise which it may have against Escrow Agent for any acts undertaken by Escrow Agent pursuant to Inktomi's direction in Escrow Agent's good faith compliance with the terms of this Agreement. 10.

Notices shall be deemed to have been given and received (i) when signed for on the return receipt, or (ii) if the party to receive notice refuses to sign the return receipt or cannot be located after the exercise of due diligence, three (3) business days after deposit of the notice in the U.S. mail, properly addressed, with postage prepaid. 11. Termination. ----------- (a) This Agreement shall terminate upon termination of both the Agreements. Upon such termination, Inktomi shall give written notice to Escrow Agent, and provide a copy of such notice to Microsoft in the manner set forth in applicable notice provisions of the Agreements. Unless Microsoft disputes such notice by written notice to that effect to Escrow Agent and Inktomi within ten (10) business days (the "Objection Period") after Microsoft's receipt of said notice from Inktomi, and provided that all fees payable to Escrow Agent for the performance of -5- its services hereunder have been fully paid, Escrow Agent shall release and return all Confidential Materials to Inktomi promptly after the expiration of the Objection Period. (b) Except as provided in Subsection 11(a) above or Section 1 hereof with respect to modification of Exhibit A hereto, this Agreement may not be terminated or modified except in writing signed by Escrow Agent, Inktomi and Microsoft. Escrow Agent may, at any time, terminate this Agreement by resigning as escrow agent hereunder. Escrow Agent shall provide Inktomi and Microsoft ninety (90) days advance written notice of its intention to resign. Unless within such period Escrow Agent receives written notice from the Inktomi and Microsoft instructing Escrow Agent to deliver the Confidential Materials to one or both of the parties, or to a third party, Escrow Agent shall deliver the Confidential Materials to Inktomi. (c) Upon the delivery of the Confidential Materials to one or both of the parties, or to a third party, as permitted hereunder, all obligations of Escrow Agent under this Agreement shall cease. 12. Bankruptcy. In the event of the commencement of a case by or against ---------- Inktomi pursuant to 11 U.S.C. Sections 301, 302, or 303, Microsoft may elect to retain its right under this Agreement pursuant to 11 U.S.C. Section 365 (n). In this regard, the Confidential Materials shall be deemed to be "intellectual property" within the meaning of 11 U.S.C. Section 101. Inktomi's obligations under this Agreement shall be binding on Inktomi's successors, including any trustee or debtor in possession that may succeed to Inktomi's rights under this Agreement. 13. Miscellany. ---------- 13.1 This Agreement shall be construed, enforced, performed and in all respects governed by and in accordance with the laws in the State of Washington. In any action or suit to enforce any right or remedy under this Agreement the prevailing party shall be entitled to recover its reasonable attorneys' fees and costs. 13.2 In the event any provision of this Agreement is rendered null, void or otherwise ineffective, then (i) the parties agree to negotiate in good faith an acceptable alternative provision which reflects as closely as possible the intent of the unenforceable provision and (ii) notwithstanding, and regardless of whether the parties reach agreement after the good faith negotiations described in clause (i) immediately above, the validity, legality and enforceability of the remaining provisions of this Agreement shall not in any way be affected or impaired thereby and shall remain in full force and effect. Section and all other headings used herein are provided for convenience only and are not to be given any legal effect or considered in interpreting any provision of this Agreement. No provision of this Agreement shall be interpreted against any party because such party or its legal representative drafted such provision. 13.3 Subject to such rights as Microsoft and/or Inktomi may have under the Agreements, no party hereto shall voluntarily or by operation of law assign, sublicense, transfer, encumber or otherwise dispose of all or any part of its interest in this Agreement without the prior written consent of the non- assigning party. Any attempted assignment, sub-license, -6- transfer, encumbrance or other disposal without such consent shall be void and shall constitute a material default and breach of this Agreement. Subject to the provisions of this Section, this Agreement shall be binding upon and inure to the benefit of each party and their respective successors and assigns. 13.4 All rights and obligations of the parties hereunder are personal to them. Except as otherwise specifically stated herein, this Agreement is not intended to benefit, nor shall it be deemed to give rise to, any rights in any third party. 13.5 Each party shall be responsible for compliance with all applicable laws, rules and regulations, if any, related to the performance of its obligations under this Agreement. 13.6 No waiver of any breach of any provision of this Agreement shall constitute a waiver of any prior, concurrent or subsequent breach of the same or any other provisions hereof or thereof, and no waiver shall be effective unless made in writing and signed by an authorized representative of the waiving party. 13.7 This Escrow Agreement (and, as between Inktomi and Microsoft, the Agreements) contains the entire agreement of the parties with respect to the premises, and may not be modified or amended except by a written instrument executed by the party sought to be charged or bound thereby. 13.8 For the purposes of this Agreement, Inktomi and Microsoft hereby designate the following individuals (and such additional individuals or substitutes therefor as may hereafter be designated by written notice from Inktomi or Microsoft, whichever is applicable) as having the authority to provide directions to Escrow Agent hereunder: Inktomi designates: David Peterschmidt, Jerry Kennelly Microsoft designates: ____________________________________________ Executed as of the date first written above. -7- Escrow Agent: DATA BASE, INC. ------------ Data Base, Inc.
