registration of at least twenty-five percent (25%) of the Registrable
Securities held by such Initiating Holders and having an aggregate offering
price to the public in excess of five million dollars ($5,000,000) (a
"Qualified Public Offering"), then the Company shall, within thirty (30) days
of the receipt thereof, give written notice of such request to all Holders
and, subject to the limitations of this Section 2.2, use its best efforts to
effect, as soon as practicable, the registration under the Securities Act of
all Registrable Securities  and the Holders request to be registered.

               (ii)  Subject to the conditions of this Section 2.2, if the
Company shall receive a written request from Inktomi that the Company file a
registration statement under the Securities Act covering the registration of
any of the Registrable Securities held by Inktomi and having an aggregate
offering price in excess of five million dollars ($5,000,000), then the
Company shall, within thirty (30) days of the receipt thereof, give written
notice of such request to all Holders and, subject to the limitations of this
Section 2.2, use its best efforts to effect, as soon as practicable, the

request made pursuant to this Section 2.2 or any request pursuant to Section
2.4 and the Company shall include such information in the written notice
referred to in Section 2.2(a) or Section 2.4(a), as applicable.  In such

her or its, securities through such underwriting, such Holder or Inktomi
shall enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting by a majority in
interest of the Initiating Holders or by Inktomi if Inktomi initiated the
registration (which underwriter or underwriters shall be reasonably
acceptable to the Company).  Notwithstanding any other provision of this
Section 2.2 or Section 2.4, if the underwriter advises the Company that
marketing factors require a limitation of the number of securities to be
underwritten (including Registrable Securities) then the Company shall so
advise Inktomi and all Holders of Registrable Securities that would otherwise
be underwritten pursuant hereto, and the number of shares that may be
included in the underwriting shall be allocated,

<PAGE>

               (i)   in the case of an underwritten registration initiated by
the Initiating Holders, to the Holders of such Registrable Securities on a
pro rata basis based on the number of Registrable Securities held by all such
Holders (including the Initiating Holders but not including the Founders); and

(including the Initiating Holders but not including the Founders).

Any Registrable Securities excluded or withdrawn from such underwriting shall
be withdrawn from the registration.

          (c)  The Company shall not be required to effect a registration
pursuant to this Section 2.2:

               (i)    as to any Holder, prior to October 29, 2001,

               (ii)   as to Inktomi, prior to one hundred eighty (180) days
following the closing of the Company's Initial Offering;

               (iii)  as to any Holder, after the Company has effected two
(2) registrations pursuant to Section 2.2(a)(i), and such registrations have
been declared effective;

               (iv)   as to Inktomi, after the Company has affected one (1)
registration pursuant to Section 2.2(a)(ii), and such registrations have been
declared or ordered effective;

               (v)    during the period starting with the date of the filing,
and ending on the date one hundred eighty (180) days following the effective
date, of the registration statement pertaining to the Initial Offering;
provided that the Company makes reasonable good faith efforts to cause such
registration statement to become effective;

               (vi)   if within thirty (30) days of receipt of a written
request pursuant to Section 2.2(a)(i) from Initiating Holders the Company
gives notice to the Holders of the Company's intention to make its Initial
Offering within ninety (90) days;

               (vii)  if within thirty (30) days of receipt of a written
request pursuant to Section 2.2(a)(ii) from Inktomi the Company gives notice
to Inktomi of the Company's intention to file a registration statement on
Form S-1 or Form S-3 within ninety (90) days; provided, however, that if the
Company gives the foregoing notice, then Inktomi shall be entitled to include
its Registrable Securities in such registration statement in accordance with
the provisions of Section 2.3 as if Inktomi were a "Holder" and PARI PASSU
with the Holders referred to in Section 2.3(a)(ii) who elect to participate

signed by the Chairman of the Board stating that in the good faith judgment
of the Board of Directors of the Company, it would be seriously detrimental

effected at such time, in which event the Company shall have the right to
defer such filing for one period of not more than ninety (90) days after
receipt of the request of the Initiating Holders or Inktomi, as the case may
be; provided, however, that such right to delay a request shall be exercised
by the Company not more than once in any twelve (12) month period.

but not limited to, registration statements relating to secondary offerings
of securities of the Company, but excluding registration statements relating
to employee benefit plans or with respect to corporate reorganizations or
other transactions under Rule 145 of the Securities Act) and will afford each
such Holder and S.L. Partners an opportunity to include in such registration
statement all or part of such Registrable Securities held by such Holder and
S.L. Partners; provided, however, that neither a Holder nor S.L. Partners
shall be eligible to so participate in such registration if such Holder or
S.L. Partners could have sold such Registrable Securities on an unrestricted
basis pursuant to Rule 144 of the Securities Act during the four-week period
immediately preceding the effectiveness of such registration; provided
further, that such participation right shall not be granted to any Holders or
to S.L. Partners following the fifth anniversary of the closing of the
Initial Offering. S.L. Partners and each Holder desiring to include in any
such registration statement all or any part of the Registrable Securities
held by it shall, within fifteen (15) days after the above-described notice
from the Company, so notify the Company in writing.  Such notice shall state
the intended method of disposition of the Registrable Securities by S.L.
Partners or such Holder.  If S.L. Partners or a Holder decides not to include
all of its Registrable Securities in any registration statement thereafter
filed by the Company, S.L. Partners and such Holder shall nevertheless
continue to have the right to include any Registrable Securities in any
subsequent registration statement or registration statements as may be filed
by the Company with respect to offerings of its scurities, all upon the terms
and conditions set forth herein.

          (a)  UNDERWRITING.  If the registration statement under which the
Company gives notice under this Section 2.3 is for an underwritten offering,
the Company shall so advise S.L. Partners and the Holders of Registrable
Securities. In such event, the right of S.L. Partners and any such Holder to
be included in a registration pursuant to this Section 2.3 shall be
conditioned upon S.L. Partners' or such Holder's participation in such
underwriting and the inclusion of S.L. Partners' or such Holder's Registrable
Securities in the underwriting to the extent provided herein. S.L. Partners
and all Holders proposing to distribute their Registrable Securities through
such underwriting shall enter into an underwriting agreement in customary
form with the underwriter or underwriters selected for such underwriting by
the Company.  Notwithstanding any other provision of the Agreement, if the
underwriter determines in good faith that marketing factors require a
limitation of the number of shares to be underwritten, the number of shares
that may be included in the underwriting shall be allocated,

               (i)    first, to the Company;

                                        7.

<PAGE>

               (ii)   second, to the Holders who are (a) Investors, (b)
holders of Series B Stock, and (c) Robert J. Lunday, Jr. on a pro rata basis
based on the total number of Registrable Securities held by such Holders and
Mr. Lunday;

               (iii)  third, to Robert J. Lunday, Jr.;

               (iv)   fourth, to Holders who are Founders (other than Mr.
Lunday) on a pro rata basis based on the total number of Registrable
Securities held by such Holders; and

               (v)    fifth, to any other shareholders of the Company (other
than a Holder), including but not limited to S.L. Partners, on a pro rata
basis.

No such reduction shall (y) reduce the securities being offered by the
Company for its own account to be included in the registration and
underwriting, or (z) reduce the amount of securities of Robert J. Lunday, Jr.
and the selling Holders who are Investors or holders of Series B Stock to
below twenty-five percent (25%) of the total amount of securities to be
included in such registration, unless such offering is the Initial Offering
and such registration does not include shares of any other selling
shareholders, in which event any or all of the Registrable Securities of the
Holders (including Mr. Lunday) may be excluded in accordance with the
preceding sentence.  In no event will shares of any other selling shareholder
be included in such registration which would reduce the number of shares
which may be included by Holders without the written consent of Holders of
not less than sixty-six and two-thirds percent (66 2/3%) of the Registrable
Securities proposed to be sold in the offering.

          (b)  RIGHT TO TERMINATE REGISTRATION.  The Company shall have the
right to terminate or withdraw any registration initiated by it under this
Section 2.3 prior to the effectiveness of such registration whether or not
S.L. Partners or any Holder has elected to include securities in such
registration. The Registration Expenses of such withdrawn registration shall
be borne by the Company in accordance with Section 2.5 hereof.

     2.4  FORM S-3 REGISTRATION.  In case the Company shall receive from any
Holder or Holders of at least fifteen percent (15%) of the Registrable
Securities or from Inktomi a written request or requests that the Company
effect a registration on Form S-3 (or any successor to Form S-3) or any
similar short-form registration statement and any related qualification or
compliance with respect to all or a part of the Registrable Securities owned
by such Holder, Holders, or Inktomi, the Company will:

          (a)  promptly give written notice of the proposed registration, and
any related qualification or compliance, to all other Holders of Registrable
Securities or to Inktomi, as the case may be; and

          (b)  as soon as practicable, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of the
Registrable Securities of such Holder, Holders or Inktomi as are specified in
such request, together with all or such portion of the Registrable Securities
of any other Holder or Holders joining in such request as are specified in a
written request given within fifteen (15) days after receipt of such written
notice from the Company;

                                        8.

<PAGE>

provided, however, that the Company shall not be obligated to effect any such
registration, qualification or compliance pursuant to this Section 2.4:

               (i)    if Form S-3 (or any successor or similar form) is not
available for such offering;

               (ii)   if the Holders or Inktomi, as the case may be, together
with the holders of any other securities of the Company entitled to inclusion
in such registration, propose to sell Registrable Securities and such other
securities (if any) at an aggregate price to the public, net of underwriting
costs, of less than five hundred thousand dollars ($500,000);

               (iii)  if the Company shall furnish to the Holders or to
Inktomi, as the case may be, a certificate signed by the Chairman of the
Board of Directors of the Company stating that in the good faith judgment of
the Board of Directors of the Company, it would be seriously detrimental to
the Company and its shareholders for such Form S-3 Registration to be
effected at such time, in which event the Company shall have the right to
defer the filing of the Form S-3 registration statement for one period of not
more than ninety (90) days after receipt of the request of the Holder,
Holders or Inktomi under this Section 2.4; provided, that such right to delay
a request shall be exercised by the Company not more than once in any twelve
(12) month period;

               (iv)   if the Company has, within the six (6) month period
preceding the date of such request, already effected one (1) registration on
Form S-3 for the Holders or Inktomi pursuant to this Section 2.4;

               (v)    in any particular jurisdiction in which the Company
would be required to qualify to do business or to execute a general consent
to service of process in effecting such registration, qualification or
compliance; or

               (vi)   as to Inktomi, after the Company shall have effected
two (2) registrations pursuant to Section 2.4, and such registrations have
been declared effective.

          (c)  Subject to the foregoing, the Company shall file a Form S-3
registration statement covering the Registrable Securities and other
securities so requested to be registered as soon as practicable after receipt
of the request or requests of the Holders or Inktomi, as the case may be.
Subject to Section 2.5 below, all Selling Expenses incurred in connection
with registrations requested pursuant to this Section 2.4 shall be paid by
the selling Holders or Inktomi pro rata in proportion to the number of shares
sold by each, and by the Company, if it participates in such registration,
pro rata in proportion to the number of shares sold by it.

     2.5  EXPENSES OF REGISTRATION.  Except as specifically provided herein,
all Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to Section 2.2 or any registration under
Section 2.3 or Section 2.4 herein shall be borne by the Company.  All Selling
Expenses incurred in connection with any registrations under those sections,
shall be borne by the holders of the securities so registered pro rata on the
basis of the number of shares so registered.  The Company shall not, however,
be required to pay for expenses of any registration proceeding begun pursuant
to Section 2.2 or 2.4, the request of which has been subsequently withdrawn
by the Holders requesting such registration or Inktomi,

                                        9.
<PAGE>

as the case may be, unless (a) the withdrawal is based upon material adverse
information concerning the Company of which the Holders requesting such
registration or Inktomi, as the case may be, were not aware at the time of
such request or (b) the Holders of a majority of Registrable Securities or
Inktomi, as the case may be, agree to forfeit their, or its, right to one
requested registration pursuant to Section 2.2 or Section 2.4, as applicable,
in which event such right shall be forfeited by all Holders in the case of a
forfeiture by any Holder.  If the Holders or Inktomi are required to pay the
Registration Expenses, such expenses shall be borne by the holders of
securities (including Registrable Securities) requesting such registration in
proportion to the number of shares for which registration was requested.  If
the Company is required to pay the Registration Expenses of a withdrawn
offering pursuant to clause (a) above, then the Holders or Inktomi, as the
case may be,  shall not forfeit their, or its, rights pursuant to Section 2.2
or Section 2.4 to a demand registration.

     2.6  OBLIGATIONS OF THE COMPANY.  Whenever required to effect the
registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

          (a)  Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use all reasonable efforts to
cause such registration statement to become effective, and, upon the request
of either the Holders of a majority of the Registrable Securities registered
thereunder or of Inktomi, keep such registration statement effective for up
to ninety (90) days or, if earlier, until the Holder, Holders or Inktomi, as
the case may be, shall have completed the distribution related thereto.

          (b)  Prepare and file with the SEC such amendments and supplements
to such registration statement and the prospectus used in connection with
such registration statement as may be necessary to comply with the provisions
of the Securities Act with respect to the disposition of all securities
covered by such registration statement.

          (c)  Furnish to the Holders, Inktomi or S.L. Partners, as the case
may be, such number of copies of a prospectus, including a preliminary
prospectus, in conformity with the requirements of the Securities Act, and
such other documents as they may reasonably request in order to facilitate
the disposition of Registrable Securities owned by them.

          (d)  Use all reasonable efforts to register and qualify the
securities covered by such registration statement under such other securities
or Blue Sky laws of such jurisdictions as shall be reasonably requested by
the Holders, Inktomi or S.L. Partners, provided that the Company shall not be
required in connection therewith or as a condition thereto to qualify to do
business or to file a general consent to service of process in any such
states or jurisdictions.

          (e)  In the event of any underwritten public offering, enter into
and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter(s) of such offering.  Each
Holder, Inktomi or S.L. Partners, as the case may be, participating in such
underwriting shall also enter into and perform his, her or its obligations
under such an agreement.

          (f)  Notify Inktomi, S.L. Partners or each Holder of Registrable
Securities covered by such registration statement at any time when a
prospectus relating thereto is required

                                        10.

<PAGE>

to be delivered under the Securities Act of the happening of any event as a
result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

          (g)  Furnish, at the request of either a majority of the Holders
participating in the registration or Inktomi (and at the request of S.L.
Partners if already requested by the Holders or Inktomi), as the case may be,
on the date that such Registrable Securities are delivered to the
underwriters for sale, if such securities are being sold through
underwriters, or, if such securities are not being sold through underwriters,
on the date that the registration statement with respect to such securities
becomes effective, (i) an opinion, dated as of such date, of the counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public
offering and reasonably satisfactory to a majority in interest of the Holders
requesting registration or to Inktomi, as the case may be, addressed to the
underwriters, if any, and to the Holders requesting registration of
Registrable Securities or to Inktomi, as the case may be, and (ii) a letter
dated as of such date, from the independent certified public accountants of
the Company, in form and substance as is customarily given by independent
certified public accountants to underwriters in an underwritten public
offering and reasonably satisfactory to a majority in interest of the Holders
requesting registration or to Inktomi, as the case may be, addressed to the
underwriters, if any, and if permitted by applicable accounting standards, to
the Holders requesting registration of Registrable Securities or to Inktomi,
as the case may be.

     2.7  TERMINATION OF REGISTRATION RIGHTS

          (a)  All registration rights granted to Holders and S.L. Partners
under this Section 2 shall terminate and be of no further force and effect
five (5) years after the date of the Company's Initial Offering.  In
addition, the registration rights of a Holder or S.L. Partners shall expire
if (a) the Company has completed its Initial Offering and is subject to the
provisions of the Exchange Act, (b) such Holder or S.L. Partners (together
with its affiliates, partners and former partners) holds less than one
percent (1%) of the Company's outstanding Common Stock (treating all share of
convertible Preferred Stock on an as converted basis) and (c) all Registrable
Securities held by and issuable to such Holder or S.L. Partners (and its
affiliates, partners and former partners) may be sold under Rule 144 during
any ninety (90) day period.

          (b)  All registration rights granted to Inktomi under this Section
2 shall terminate and be of no further force and effect two (2) years after
the date of the Company's Initial Offering.  In addition, the registration
rights of Inktomi shall expire if (a) the Company has completed its Initial
Offering and is subject to the provisions of the Exchange Act, (b) Inktomi
(together with its affiliates) holds less than one percent (1%) of the
Company's outstanding Common Stock and (c) all Registrable Securities held by
and issuable to Inktomi (and its affiliates) may be sold under Rule 144
during any ninety (90) day period.

     2.8  DELAY OF REGISTRATION; FURNISHING INFORMATION

          (a)  Neither Inktomi, S.L. Partners nor any Holder shall have any
right to obtain or seek an injunction restraining or otherwise delaying any
such registration as the result

                                        11.

<PAGE>

of any controversy that might arise with respect to the interpretation or
implementation of this Section 2.

          (b)  It shall be a condition precedent to the obligations of the
Company to take any action pursuant to Section 2.2, 2.3 or 2.4 that the
selling Holders, S.L. Partners or Inktomi, as the case may be, shall furnish
to the Company such information regarding such Holders, S.L. Partners or
Inktomi, the Registrable Securities held by such Holders, S.L. Partners or
Inktomi and the intended method of disposition of such securities as shall be
required to effect the registration of their Registrable Securities.

          (c)  The Company shall have no obligation with respect to any
registration requested pursuant to Section 2.2 or Section 2.4 if, due to the
operation of subsection 2.2(b), the number of shares or the anticipated
aggregate offering price of the Registrable Securities to be included in the
registration does not equal or exceed the number of shares or the anticipated
aggregate offering price required to originally trigger the Company's
obligation to initiate such registration as specified in Section 2.2 or
Section 2.4, whichever is applicable.

     2.9  INDEMNIFICATION.  In the event any Registrable Securities are
included in a registration statement under Sections 2.2, 2.3 or 2.4:

          (a)  To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, S.L. Partners, Inktomi, the partners, officers,
directors and legal counsel of each Holder, S.L. Partners or Inktomi, any
underwriter (as defined in the Securities Act) for such Holder, S.L. Partners
or Inktomi and each person, if any, who controls such Holder, S.L. Partners,
Inktomi or underwriter within the meaning of the Securities Act or the
Exchange Act, against any losses, claims, damages, or liabilities (joint or
several) to which they may become subject under the Securities Act, the
Exchange Act or other federal or state law, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are
based upon any of the following statements, omissions or violations
(collectively a "Violation") by the Company: (i) any untrue statement or
alleged untrue statement of a material fact contained in such registration
statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements thereto, (ii) the omission or
alleged omission to state therein a material fact required to be stated
therein, or necessary to make the statements therein not misleading or (iii)
any violation or alleged violation by the Company of the Securities Act, the
Exchange Act, any state securities law or any rule or regulation promulgated
under the Securities Act, the Exchange Act or any state securities law in
connection with the offering covered by such registration statement; and the
Company will reimburse Inktomi, S.L. Partners and each such Holder, partner,
officer, director, legal counsel, underwriter or controlling person for any
legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that the indemnity agreement contained in this Section
2.9(a) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the
consent of the Company, which consent shall not be unreasonably withheld, nor
shall the Company be liable to an indemnified party for any such loss, claim,
damage, liability or action to the extent that it arises out of or is based
upon a Violation which occurs in reliance upon and in conformity with written
information furnished expressly for use in connection with such registration
by such indemnified party.

                                        12.
<PAGE>

          (b)  To the extent permitted by law, each Holder will, if
Registrable Securities held such Holder are included in the securities as to
which such registration qualifications or compliance is being effected,
indemnify and hold harmless the Company, each of its directors, officers and
legal counsel, and each person, if any, who controls the Company within the
meaning of the Securities Act, any underwriter, Inktomi, S.L. Partners or any
of Inktomi's or S.L. Partners' directors, officers or any person who controls
Inktomi or S.L. Partners, if any, and any other Holder selling securities
under such registration statement or any of such Holder's other partners,
directors or officers or any person who controls such Holder, against any
losses, claims, damages or liabilities (joint or several) to which the
Company or any such director, officer, controlling person, underwriter,
Inktomi, S.L. Partners or any of Inktomi's or S.L. Partners' directors or
officers or any person who controls Inktomi or S.L. Partners, if any, or
other such Holder, or partner, director, officer or controlling person of
such other Holder may become subject under the Securities Act, the Exchange
Act or other federal or state law, insofar as such losses, claims, damages or
liabilities (or actions in respect thereto) arise out of or are based upon
any Violation, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished by such Holder under an instrument duly executed by such Holder and
stated to be specifically for use in connection with such registration; and
each such Holder will reimburse any legal or other expenses reasonably
incurred by the Company or any such director, officer, legal counsel,
controlling person, underwriter Inktomi, S.L. Partners or any of Inktomi's or
S.L. Partners' directors, officers, legal counsel or controlling person, if
any, or other Holder, or partner, officer, director, legal counsel or
controlling person of such other Holder in connection with investigating or
defending any such loss, claim, damage, liability or action if it is
judicially determined that there was such a Violation; provided, however,
that the indemnity agreement contained in this Section 2.9(b) shall not apply
to amounts paid in settlement of any such loss, claim, damage, liability or
action if such settlement is effected without the consent of the indemnifying
Holder, which consent shall not be unreasonably withheld; provided further,
that in no event shall any indemnity under this Section 2.9 exceed the
proceeds from the offering received by such Holder.

          (c)  To the extent permitted by law, Inktomi will, if Registrable
Securities held by Inktomi are included in the securities as to which such
registration qualifications or compliance is being effected, indemnify and
hold harmless the Company, each of its directors, officers and legal counsel,
and each person, if any, who controls the Company within the meaning of the
Securities Act, any underwriter, S.L. Partners and any other Holder selling
securities under such registration statement or any of S.L. Partners' or such
other Holder's partners, directors or officers or any person who controls
S.L. Partners or such Holder, against any losses, claims, damages or
liabilities (joint or several) to which the Company, S.L. Partners or any
such director, officer, controlling person, underwriter or other such Holder,
or partner, director, officer or controlling person of S.L. Partners or such
other Holder may become subject under the Securities Act, the Exchange Act or
other federal or state law, insofar as such losses, claims, damages or
liabilities (or actions in respect thereto) arise out of or are based upon
any Violation, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished by Inktomi under an instrument duly executed by Inktomi and stated
to be specifically for use in connection with such registration; and Inktomi
will reimburse any legal or other expenses reasonably incurred by the Company
or any such director, officer, legal counsel, controlling person,
underwriter, S.L.

                                        13.

<PAGE>

Partners or other Holder, or partner, officer, director, legal counsel or
controlling person of S.L. Partners or such other Holder in connection with
investigating or defending any such loss, claim, damage, liability or action
if it is judicially determined that there was such a Violation; provided,
however, that the indemnity agreement contained in this Section 2.9(c) shall
not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of
Inktomi, which consent shall not be unreasonably withheld; provided further,
that in no event shall any indemnity under this Section 2.9 exceed the
proceeds from the offering received by Inktomi.

          (d)  To the extent permitted by law, S.L. Partners will, if
Registrable Securities held by S.L. Partners are included in the securities
as to which such registration qualifications or compliance is being effected,
indemnify and hold harmless the Company, each of its directors, officers and
legal counsel, and each person, if any, who controls the Company within the
meaning of the Securities Act, any underwriter, Inktomi and any other Holder
selling securities under such registration statement or any of Inktomi's or
such other Holder's partners, directors or officers or any person who
controls Inktomi or such Holder, against any losses, claims, damages or
liabilities (joint or several) to which the Company, Inktomi or any such
director, officer, controlling person, underwriter or other such Holder, or
partner, director, officer or controlling person of Inktomi or such other
Holder may become subject under the Securities Act, the Exchange Act or other
federal or state law, insofar as such losses, claims, damages or liabilities
(or actions in respect thereto) arise out of or are based upon any Violation,
in each case to the extent (and only to the extent) that such Violation
occurs in reliance upon and in conformity with written information furnished
by S.L. Partners under an instrument duly executed by S.L. Partners and
stated to be specifically for use in connection with such registration; and
S.L. Partners will reimburse any legal or other expenses reasonably incurred
by the Company or any such director, officer, legal counsel, controlling
person, underwriter, Inktomi or other Holder, or partner, officer, director,
legal counsel or controlling person of Inktomi or such other Holder in
connection with investigating or defending any such loss, claim, damage,
liability or action if it is judicially determined that there was such a
Violation; provided, however, that the indemnity agreement contained in this
Section 2.9(d) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected
without the consent of S.L. Partners, which consent shall not be unreasonably
withheld; provided further, that in no event shall any indemnity under this
Section 2.9 exceed the proceeds from the offering received by S.L. Partners.

          (e)  Promptly after receipt by an indemnified party under this
Section 2.9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect
thereof is to be made against any indemnifying party under this Section 2.9,
deliver to the indemnifying party a written notice of the commencement
thereof and the indemnifying party shall have the right to participate in
and, to the extent the indemnifying party so desires, jointly with any other
indemnifying party similarly noticed, to assume the defense thereof with
counsel mutually satisfactory to the parties; provided, however, that an
indemnified party shall have the right to retain its own counsel, with the
fees and expenses to be paid by the indemnifying party, if representation of
such indemnified party by the counsel retained by the indemnifying party
would be inappropriate due to actual or potential differing interests between
such indemnified party and any other party represented by such counsel in
such proceeding.  The failure to deliver written notice to the indemnifying
party

                                        14.

<PAGE>

within a reasonable time of the commencement of any such action, if
materially prejudicial to its ability to defend such action, shall relieve
such indemnifying party of any liability to the indemnified party under this
Section 2.9, but the omission so to deliver written notice to the
indemnifying party will not relieve it of any liability that it may have to
any indemnified party otherwise than under this Section 2.9.

          (f)  If the indemnification provided for in this Section 2.9 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any losses, claims, damages or liabilities referred to
herein, the indemnifying party, in lieu of indemnifying such indemnified
party thereunder, shall to the extent permitted by applicable law contribute
to the amount paid or payable by such indemnified party as a result of such
loss, claim, damage or liability in such proportion as is appropriate to
reflect the relative fault of the indemnifying party on the one hand and of
the indemnified party on the other in connection with the Violation(s) that
resulted in such loss, claim, damage or liability, as well as any other
relevant equitable considerations.  The relative fault of the indemnifying
party and of the indemnified party shall be determined by a court of law by
reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission to state a material fact relates
to information supplied by the indemnifying party or by the indemnified party
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission; provided, that
in no event shall any contribution by a Holder, S.L. Partners or by Inktomi
hereunder exceed the proceeds from the offering received by such Holder, S.L.
Partners or Inktomi.

          (g)  The obligations of the Company, the Holders, S.L. Partners and
Inktomi under this Section 2.9 shall survive completion of any offering of
Registrable Securities in a registration statement and the termination of
this Agreement.  No indemnifying party, in the defense of any such claim or
litigation, shall, except with the consent of each indemnified party, consent
to entry of any judgment or enter into any settlement which does not include
as an unconditional term thereof the giving by the claimant or plaintiff to
such indemnified party of a release from all liability in respect to such
claim or litigation.

     2.10 ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause the Company
to register Registrable Securities pursuant to this Section 2 may be assigned
(a) by a Holder to a transferee or assignee of Registrable Securities which
(i) previously holds Registrable Securities, (ii) is a subsidiary, parent,
general partner, limited partner or retired partner of a Holder, or is a
Holder's family member or trust for the benefit of an individual Holder, or
(iii) acquires at least Seventy-five Thousand (75,000) shares of Registrable
Securities (as adjusted for stock splits and combinations); (b) by Inktomi to
a transferee or assignee of Registrable Securities which (i) previously holds
Registrable Securities, (ii) is a subsidiary or parent of Inktomi or an
entity that controls, is controlled by or is under common control with
Inktomi, or (iii) acquires at least Seventy-five Thousand (75,000) shares of
Registrable Securities (as adjusted for stock splits and combinations) and

set forth in this Agreement.

     2.11 AMENDMENT OF REGISTRATION RIGHTS.  Any provision of this Section 2 may

particular instance and either retroactively or prospectively), only with the
written consent of the Company, the Holders of at least sixty-six and two-thirds
percent (66 2/3%) of the Registrable Securities then outstanding; provided,
however, that any amendment adversely affecting the rights of Inktomi or S.L.

prospective holder of any securities of the Company that would grant such holder
or prospective holder rights to register its shares in any registration filed

PASSU or superior to Inktomi's rights, the Company shall not enter into such
agreement granting such rights without the written consent of Inktomi.

     2.13 "MARKET STAND-OFF" AGREEMENT.

underwriters of Common Stock (or other securities) of the Company not to exceed
one hundred eighty (180) days following the effective date of a registration

registration relating solely to a Commission Rule 145 transaction on Form S-4 or
similar forms

                                     16.

the general public;

          (b)  File with the SEC, in a timely manner, all reports and other

          (c)  So long as a Holder, Inktomi or S.L. Partners, as the case may
be, own any Registrable Securities, furnish to such Holder, Inktomi and S.L.
Partners forthwith upon request: a written statement by the Company as to its
compliance with the reporting requirements of said Rule 144 of the Securities
Act and with the reporting requirements of the Exchange Act (at any time after

annual or quarterly report of the Company; and such other reports and documents
as a Holder, S.L. Partners or Inktomi, as the case may be, may reasonably
request in availing himself, herself or itself of any rule or regulation of the
SEC allowing it to sell any such securities without registration.

or reporting requirements imposed by the Code on issuers of Qualified Small
Business Stock) to cause such shares of Series C Preferred Stock, or the Common
Stock into which they are converted, to qualify as Qualified Small Business
Stock; provided, however, that "commercially reasonable efforts" as used in this
Section 3.29 shall not be construed to require the Company to operate its

<PAGE>

Directors; provided, however, that the Company reserves the right to exclude
such representative from access to any material or meeting or portion thereof
if the Company believes upon advice of counsel that such exclusion is
reasonably necessary to preserve the attorney-client privilege, to protect
highly confidential proprietary information or for other similar reasons.

SECTION 4 RIGHT TO MAINTAIN INTEREST

     4.1  SUBSEQUENT OFFERINGS.  Each Investor and holder of Series B Stock
shall have a right to purchase its Pro Rata Share (as defined herein) of all
Equity Securities, as defined below, that the Company may, from time to time,
propose to sell and issue after the date of this Agreement, other than the
Equity Securities excluded by Section 4.6 hereof.  The Company may, at its
election, sell such Investor and holder of Series B Stock its Pro Rata Amount of
Equity Securities at the initial closing of the sale of Equity Securities or at
a subsequent closing of which shall take place within ninety (90) days of the
initial closing.  The Pro Rata Share of an Investor and holder of Series B
Stock shall be equal to the ratio of (a) the number of shares of the Company's
Common Stock (including all shares of Common Stock issued or issuable upon
conversion of the Preferred Stock) which such Investor and holder of Series B
Stock is deemed to hold immediately prior to the issuance of such Equity
Securities to (b) the total number of shares of the Company's outstanding Common
Stock (including all shares of Common Stock issued or issuable upon conversion
of the Preferred Stock) immediately prior to the issuance of the Equity
Securities.  The term "Equity Securities" shall mean (i) any Common Stock,
Preferred Stock or other security of the Company, (ii) any security convertible,
with or without consideration, into any Common Stock, Preferred Stock or other
security (including any option to purchase such a convertible security),

Common Stock, Preferred Stock or other security or (iv) any such warrant or
right.

Securities, it shall give each Investor and holder of Series B Stock written
notice before such issuance or within ten (10) days thereafter, describing the
type of Equity Securities, the price and number of shares and the general terms
and conditions upon which the Company proposes to issue or has issued the same.
Each Investor and holder of Series B Stock shall have thirty (30) days from the
giving of such notice to agree to purchase up to the amount of Equity Securities
equal to Pro Rata Share of such Equity Securities of the Investor and holder of
Series B Stock for the price and upon the general terms and conditions specified
in the notice by giving written notice to the Company and stating therein the
quantity of Equity Securities to be purchased.  Any such purchase shall occur at
the initial closing of the sale of Equity Securities or, at the Company's
election, at a subsequent closing within ninety (90) days of the initial
closing.  Notwithstanding the foregoing, the Company shall not be required to
offer or sell such Equity Securities to any Investor and holder of Series B
Stock who would cause the Company to be in violation of applicable federal
securities laws by virtue of such offer or sale.

     4.3  ISSUANCE OF EQUITY SECURITIES TO OTHER PERSONS.  If not all of the
Investors and holders of Series B Stock elect to purchase their Pro Rata Share
of the Equity Securities, then the Company shall promptly notify in writing the
Investors and holders of Series B Stock who do so elect and shall offer such
Investors and holders of Series B Stock the right to acquire such unsubscribed
shares.  Each Investor and holder of Series B Stock shall have fifteen (15) days

                                     21.

<PAGE>

after receipt of such notice to notify the Company of its election to purchase
all or a portion thereof of the unsubscribed shares.  If the Investors and
holders of Series B Stock fail to exercise in full the right to maintain
interest within said forty-five (45) day period set forth in Section 4.2 and
4.3, the Company shall have ninety (90) days thereafter to sell the Equity
Securities in respect of which the rights of the Investors and holders of
Series B Stock were not exercised, at a price and upon general terms and
conditions no more favorable to the purchasers thereof than specified in the
Company's notice to the Investors and holders of Series B Stock pursuant to
Section 4.2 hereof.  If the Company has not sold such Equity Securities within
ninety (90) days of the notice provided pursuant to Section 4.2, the Company
shall not thereafter issue or sell any Equity Securities without first offering
such securities to the Investors and holders of Series B Stock in the manner
provided above.

     4.4  TERMINATION OF RIGHTS TO MAINTAIN INTEREST.  The rights to maintain
interest established by this Section 4 shall not apply to, and shall terminate
upon (i) the effective date of the registration statement pertaining to the
Initial Offering or (ii) a Change in Control.

     4.5  TRANSFER OF RIGHTS TO MAINTAIN INTEREST.  The rights to maintain
interest of each Investor and holder of Series B Stock under this Section 4 may
be transferred to the same parties, subject to the same restrictions as any
transfer of registration rights pursuant to Section 2.10.

this Section 4 shall have no application to any of the following Equity
Securities:

          (a)  shares of Common Stock (and/or options, warrants or other Common

Re: Offer of Employment

Dear Tony:

Reference is made to the Offer of Employment letter dated August 27, 1999
("Offer Letter"). This letter sets forth certain other agreements and
clarifications with respect to my employment with InterNAP.

In the event my employment with InterNAP is terminated for reasons other than
(i) my voluntary resignation, (ii) my death or (iii) for Cause (as defined
below) within the twelve month period of the "date of grant" referenced in the
Offer Letter then I will fully and immediately vest in the 50,000 options to
purchase InterNAP stock (at the price per share of $8.00) in which I would have
vested through the first anniversary of the date of grant had my employment with
InterNAP continued through such twelve-month period.

In addition (and without limitation of the immediately preceding paragraph),
in the event my employment with InterNAP is terminated for reasons other than
(i) my voluntary resignation, (ii) my death or (iii) for Cause (as defined
below), I will receive no less than six months severance pay (based upon my
then applicable base salary and expected bonus), and will fully and
immediately vest in such options to purchase InterNAP stock (at the
applicable strike price) to which I would have vested had my employment with
InterNAP continued through such six month period. Furthermore, all health,
life and other insurance/benefits shall continue through such severance
period as though my employment with InterNAP continued.

For purposes of this letter "Cause" shall mean (A) the conviction or a plea of
nolo contendere to a felony involving fraud, dishonesty or moral turpitude, (B)
the commission of a fraud, misappropriation, theft or similar malfeasance
involving the assets of InterNAP, (C) an intentional act materially adverse to
InterNAP.

The strike price applicable my option to purchase the 200,000 shares of
InterNAP stock referred to in the Offer Letter is $8.00 per share.

For the avoidance of doubt, Paragraph 11(e) of the InterNAP Network Services
Corporation 1999 Equity Incentive Plan, takes precedence over Paragraph 11(c).

Very truly yours,

/s/ Richard K. Cotton

ACCEPTED AND AGREED:

INTERNAP NETWORK SERVICES CORPORATION
