judgment, without any limitation as to volume pursuant to Rule 144 (or any

                                       5
<PAGE>   9

            (c) Holders of Registrable Securities. A Person is deemed to be a
holder of Registrable Securities whenever such Person owns of record Registrable
Securities, or holds an option to purchase, or a security convertible into or
exercisable or exchangeable for, Registrable Securities whether or not such
acquisition or conversion has actually been effected. If the Company receives
conflicting instructions, notices or elections from two or more Persons with
respect to the same Registrable Securities, the Company may act upon the basis
of the instructions, notice or election received from the registered owner of
such Registrable Securities. Registrable Securities issuable upon exercise of an
option or upon conversion of another security shall be deemed outstanding for
the purposes of this Agreement.

        3. Demand Registration.

            (a) Request for Demand Registration. At any time after the date
hereof, one or more of the General Atlantic Stockholders as a group, acting
through GAP LLC or its written designee (the "Initiating Holders"), may make a
written request to the Company to register, and the Company shall register,
under the Securities Act (other than pursuant to a Registration Statement on
Form S-4 or S-8 or any successor thereto) (a "Demand Registration"), the number
of Registrable Securities stated in such request; provided, however, that (x)
subject to Section 3(e), the Company shall not be obligated to effect more than
one such Demand Registration for the General Atlantic Stockholders and (y) the
Company shall not be obligated to effect a registration pursuant to this Section
3(a) during such time as the Company has an "evergreen" shelf registration with
respect to all such Registrable Securities pursuant to Rule 415 under the
Securities Act on form S-3 (or any successor form) and such shelf registration
has been declared, and remains, effective. For purposes of the preceding
sentence, two or more Registration Statements filed in response to one demand
shall be counted as one Demand Registration. If the Board of Directors, in its
good faith judgment, determines that any registration of Registrable Securities
should not be made or continued because it would materially interfere with any
material financing, acquisition, corporate reorganization or merger or other
material transaction involving the Company (a "Valid Business Reason"), the
Company may (x) postpone filing a Registration Statement relating to a Demand
Registration until such Valid Business Reason no longer exists, but in no event
for more than ninety (90) days, and (y) in case a Registration Statement has
been filed relating to a Demand Registration, if the Valid Business Reason has
not resulted from actions taken by the Company, the Company, upon the approval
of a majority of the Board of Directors, such majority to include at least one
director elected by the holders of the Series F Preferred Stock, may cause such
Registration Statement to be withdrawn and its effectiveness terminated or may
postpone amending or supplementing such Registration Statement. The Company
shall give written notice of its determination to postpone or withdraw a
Registration Statement and of the fact that the Valid Business Reason for such
postponement or withdrawal no longer exists, in each case, promptly after the
occurrence thereof. Notwithstanding anything to the contrary contained herein,
the Company may not postpone or withdraw a filing under this Section 3(a) more
than once in any twelve (12) month period. Each request for a Demand
Registration by the Initiating Holders shall state the amount of the Registrable
Securities proposed to be sold and the intended method of disposition thereof.




                                       6
<PAGE>   10

            (b) Incidental or "Piggy-Back" Rights with Respect to a Demand
Registration. Each of the Designated Holders (other than Initiating Holders
which have requested a registration under Section 3(a)) may offer its or his
Registrable Securities under any Demand Registration pursuant to this Section
3(b). Within seven (7) days after the receipt of a request for a Demand
Registration from an Initiating Holder, the Company shall (i) give written
notice thereof to all of the Designated Holders (other than Initiating Holders
which have requested a registration under Section 3(a)) and (ii) subject to
Section 3(f), include in such registration all of the Registrable Securities
held by such Designated Holders from whom the Company has received a written
request for inclusion therein within ten (10) days of the receipt by such
Designated Holders of such written notice referred to in clause (i) above. Each
such request by such Designated Holders shall specify the number of Registrable
Securities proposed to be registered. The failure of any Designated Holder to
respond within such 10-day period referred to in clause (ii) above shall be
deemed to be a waiver of such Designated Holder's rights under this Section 3
with respect to such Demand Registration. Any Designated Holder may waive its
rights under this Section 3 prior to the expiration of such 10-day period by
giving written notice to the Company, with a copy to the Initiating Holders. If
a Designated Holder sends the Company a written request for inclusion of part or
all of such Designated Holder's Registrable Securities in a registration, such
Designated Holder shall not be entitled to withdraw or revoke such request
without the prior written consent of the Company in its sole discretion unless,
as a result of facts or circumstances arising after the date on which such
request was made relating to the Company or to market conditions, such
Designated Holder reasonably determines that participation in such registration
would have a material adverse effect on such Designated Holder.

            (c) Effective Demand Registration. The Company shall use its
commercially reasonable efforts to cause any such Demand Registration to become
and remain effective not later than sixty (60) days after it receives a request
under Section 3(a) hereof. A registration shall not constitute a Demand
Registration until it has become effective and remains continuously effective
for the lesser of (i) the period during which all Registrable Securities
registered in the Demand Registration are sold and (ii) 120 days; provided,
however, that a registration shall not constitute a Demand Registration if (x)
after such Demand Registration has become effective, such registration or the
related offer, sale or distribution of Registrable Securities thereunder is
interfered with by any stop order, injunction or other order or requirement of
the Commission or other governmental agency or court for any reason not
attributable to the Initiating Holders and such interference is not thereafter
eliminated or (y) the conditions specified in the underwriting agreement, if
any, entered into in connection with such Demand Registration are not satisfied
or waived, other than by reason of a failure by the Initiating Holder.

            (d) Expenses. The Company shall pay all Registration Expenses in
connection with a Demand Registration, whether or not such Demand Registration
becomes effective.




                                       7
<PAGE>   11

            (e) Additional Demand Registration. If at least seventy-five percent
(75%) of the Registrable Securities proposed to be registered in such Demand
Registration are not included in such Demand Registration, then the General
Atlantic Stockholders as a group shall have the right to require the Company to
effect an additional registration under the Securities Act of all or part of the
Registrable Securities held by such General Atlantic Stockholders in accordance
with the provisions of this Section 3, and the Company shall pay the
Registration Expenses in connection with such additional registration.

            (f) Underwriting Procedures. If the Initiating Holders holding a
majority of the Registrable Securities held by all of the Initiating Holders so
elect, the Company shall use its commercially reasonable efforts to cause such
Demand Registration to be in the form of a firm commitment underwritten offering
and the managing underwriter or underwriters selected for such offering shall be
the Approved Underwriter selected in accordance with Section 3(g). In connection
with any Demand Registration under this Section 3 involving an underwritten
offering, none of the Registrable Securities held by any Designated Holder
making a request for inclusion of such Registrable Securities pursuant to
Section 3(b) hereof shall be included in such underwritten offering unless such
Designated Holder accepts the terms of the offering as agreed upon by the
Company, the other Initiating Holders and the Approved Underwriter, and then,
subject to the immediately following sentence, only in such quantity as will
not, in the opinion of the Approved Underwriter, jeopardize the success of such
offering by the Initiating Holders. If the Approved Underwriter advises the
Company that the aggregate amount of such Registrable Securities requested to be
included in such offering is sufficiently large to have a material adverse
effect on the success of such offering, then the Company shall include in such
registration only the aggregate amount of Registrable Securities that the
Approved underwriter believes may be sold without any such material adverse
effect and shall reduce the amount of Registrable Securities to be included in
such registration, first, as to the Company, second, as to any other
stockholders of the Company who hold similar registration rights to the
Designated Holders hereunder pursuant to other registration rights agreements as
a group, pro rata within each group based upon the number of Registrable
Securities or other similar securities owned by each such other stockholder of
the Company as a group, if any, and third, as to the (i) Designated Holders and
(ii) any other stockholders of the Company who hold and have exercised similar
registration rights as the Initiating Holders hereunder pursuant to other
registration rights agreements as a group, pro rata within each group based on
the number of Registrable Securities or other similar securities owned by each
such Designated Holder or each such other stockholder of the Company.

            (g) Selection of Underwriters. If any Demand Registration, or S-3
Registration, as the case may be, of Registrable Securities is in the form of an
underwritten offering, the Company shall select and obtain an investment banking
firm of national reputation to act as the managing underwriter of the offering
(the "Approved Underwriter"); provided, however, that the Approved Underwriter
shall, in any case, also be approved by the Initiating Holders or S-3 Initiating
Holders, as the case may be, such approval not to be unreasonably withheld.



                                       8
<PAGE>   12

        4. Incidental or "Piggy-Back" Registration.

            (a) Request for Incidental Registration. If the Company proposes to
file a Registration Statement under the Securities Act with respect to an
offering by the Company for its own account (other than a Registration Statement
on Form S-4 or S-8 or any successor thereto) or for the account of any
stockholder of the Company other than the Designated Holders, then the Company
shall give written notice of such proposed filing to each of the Designated
Holders at least twenty (20) days before the anticipated filing date, and such
notice shall describe the proposed registration and distribution and offer such
Designated Holders the opportunity to register the number of Registrable
Securities as each such Designated Holder may request (an "Incidental
Registration"). The Company shall use its commercially reasonable efforts
(within twenty (20) days of the notice provided for in the preceding sentence)
to cause the managing underwriter or underwriters in the case of a proposed
underwritten offering (the "Company Underwriter") to permit each of the
Designated Holders who have requested in writing to participate in the
Incidental Registration to include its or his Registrable Securities in such
offering on the same terms and conditions as the securities of the Company or
the account of such other stockholder, as the case may be, included therein. In
connection with any Incidental Registration under this Section 4(a) involving an
underwritten offering, the Company shall not be required to include any
Registrable Securities in such underwritten offering unless the Designated
Holders thereof accept the terms of the underwritten offering as agreed upon
between the Company, such other stockholders, if any, and the Company
Underwriter, and then, subject to the immediately following sentence, only in
such quantity as the Company Underwriter believes will not jeopardize the
success of the offering by the Company. If the Company Underwriter determines
that the registration of all or part of the Registrable Securities which the
Designated Holders have requested to be included would materially adversely
affect the success of such offering, then the Company shall be required to
include in such Incidental Registration, to the extent of the amount that the
Company Underwriter believes may be sold without causing such adverse effect,
first, all of the securities to be offered for the account of the Company,
second, the Registrable Securities to be offered for the account of the
Designated Holders pursuant to this Section 4 or securities to be offered for
the account of other stockholders of the Company having similar "piggy-back"
registration rights to the Designated Holders hereunder pursuant to other
similar registration rights agreements, as a group pro rata based on the number
of Registrable Securities or similar securities owned by each such Designated
Holder or each such other stockholder of the Company, and third, any other
securities requested to be included in such offering.

            (b) Expenses. The Company shall bear all Registration Expenses in
connection with any Incidental Registration pursuant to this Section 4, whether
or not such Incidental Registration becomes effective.

        5. Shelf Registration.

            (a) Request for a Form S-3 Shelf Registration. In the event that the
Company shall receive from the Designated Holders of at least 66 2/3% of the
Registrable Securities (the "S-3 Initiating Holders"), a written request that
the Company register for an offering to be made on a continuous basis pursuant
to Rule 415 under the Securities Act on Form S-3 (or any successor form then in
effect) (an "S-3 Registration"),



                                       9
<PAGE>   13

all or a portion of the Registrable Securities owned by such S-3 Initiating
Holders, the Company shall give written notice of such request to all of the
Designated Holders (other than S-3 Initiating Holders which have requested an
S-3 Registration under this Section 5(a)) at least ten (10) days before the
anticipated filing date of such Form S-3, and such notice shall describe the
proposed registration and offer such Designated Holders the opportunity to
register the number of Registrable Securities as each such Designated Holder may
request in writing to the Company, given within ten (10) days after their
receipt from the Company of the written notice of such registration. With
respect to each S-3 Registration, the Company shall subject to Section 5(b) (i)
include in such offering the Registrable Securities of the S-3 Initiating
Holders and (ii) use its reasonable best efforts to (x) cause such registration
pursuant to this Section 5(a) to become and remain effective as soon as
practicable, but in any event not later than forty-five (45) days after it
receives a request therefor and (y) include in such offering the Registrable
Securities of the Designated Holders (other than S-3 Initiating Holders which
have requested an S-3 Registration under this Section 5(a)) who have requested
in writing to participate in such registration on the same terms and conditions
as the Registrable Securities of the S-3 Initiating Holders included therein.
The Company shall use its best efforts to keep the S-3 Registration continuously
effective under the Securities Act until all the Registrable Securities are
disposed of in accordance with the plan of distribution for such S-3
Registration.

            (b) Form S-3 Underwriting Procedures. If the S-3 Initiating Holders
holding a majority of the Registrable Securities held by all of the S-3
Initiating Holders so elect, the Company shall use its commercially reasonable
efforts to cause such S-3 Registration pursuant to this Section 5 to be in the
form of a firm commitment underwritten offering and the managing underwriter or
underwriters selected for such offering shall be the Approved Underwriter
selected in accordance with Section 3(g). In connection with any S-3
Registration under Section 5(a) involving an underwritten offering, the Company
shall not be required to include any Registrable Securities in such underwritten
offering unless the Designated Holders thereof accept the terms of the
underwritten offering as agreed upon between the Company, the Approved
Underwriter and the S-3 Initiating Holders, and then only in such quantity as
such underwriter believes will not jeopardize the success of such offering by
the S-3 Initiating Holders. If the Approved Underwriter believes that the
registration of all or part of the Registrable Securities which the S-3
Initiating Holders and the other Designated Holders have requested to be
included would materially adversely affect the success of such public offering,
then the Company shall be required to include in the underwritten offering, to
the extent of the amount that the Approved Underwriter believes may be sold
without causing such adverse effect, first, all of the Registrable Securities to
be offered for the account of the S-3 Initiating Holders, the Registrable
Securities to be offered for the account of the other Designated Holders who
requested inclusion of their Registrable Securities pursuant to Section 5(a),
and any other stockholder of the Company having similar shelf registration
rights as the S-3 Initiating Holders hereunder pursuant to other similar
registration rights agreements, as a group pro rata based on the number of
Registrable Securities or other similar securities owned by such S-3 Initiating
Holders, Designated Holders or other stockholders of the Company, second, the
Registrable Securities to be offered for the account of any other stockholders
of the Company who


                                       10
<PAGE>   14

are entitled to registration of securities of the Company based upon similar
rights to those in Section 5(a), pro rata based upon the number of registrable
securities owned by such other stockholders, and third, any other securities
requested to be included in such offering.

            (c) Limitations on Form S-3 Registrations. If the Board of Directors
has a Valid Business Reason, the Company may (x) postpone filing a Registration
Statement relating to a S-3 Registration until such Valid Business Reason no
longer exists, but in no event for more than ninety (90) days, and (y) in case a
Registration Statement has been filed relating to a S-3 Registration, if the
Valid Business Reason has not resulted from actions taken by the Company, the
Company, upon the approval of a majority of the Board of Directors, such
majority to include at least one director elected by the holders of the Series F
Preferred Stock, may cause such Registration Statement to be withdrawn and its
effectiveness terminated or may postpone amending or supplementing such
Registration Statement. The Company shall give written notice of its
determination to postpone or withdraw a Registration Statement and of the fact
that the Valid Business Reason for such postponement or withdrawal no longer
exists, in each case, promptly after the occurrence thereof. Notwithstanding
anything to the contrary contained herein, the Company may not postpone or
withdraw a filing due to a Valid Business Reason more than once in any twelve
(12) month period. In addition, the Company shall not be required to effect any
registration pursuant to Section 5(a), (i) within ninety (90) days after the
effective date of any other Registration Statement of the Company, (ii) if
within the twelve (12) month period preceding the date of such request, the
Company has effected two (2) registrations on Form S-3 pursuant to Section 5(a),
and (iii) if Form S-3 is not available for such offering by the S-3 Initiating
Holders.

            (d) Expenses. The Company shall bear all Registration Expenses in
connection with any S-3 Registration pursuant to this Section 5, whether or not
such S-3 Registration become effective.

            (e) No Demand Registration. No registration requested by any
Designated Holder pursuant to this Section 5 shall be deemed a Demand
Registration pursuant to Section 3.

        6. Holdback Agreements.

            (a) Restrictions on Public Sale by Designated Holders. To the extent
(i) requested by the Approved Underwriter or the Company Underwriter, as the
case may be, in the case of an underwritten public offering and (ii) all of the
Company's officers, directors and holders in excess of two percent (2%) of its
outstanding capital stock execute agreements identical to those referred to in
this Section 6(a), each Designated Holder agrees (x) not to effect any public
sale or distribution of any Registrable Securities or of any securities
convertible into or exchangeable or exercisable for such Registrable Securities,
including a sale pursuant to Rule 144 under the Securities Act, or offer to
sell, contract to sell (including without limitation any short sale), grant any
option to purchase or enter into any hedging or similar transaction with the
same


                                       11
<PAGE>   15

economic effect as a sale any Registrable Securities and (y) not to make any
request for a Demand Registration or S-3 Registration under this Agreement,
during the ninety (90) day period or such shorter period, if any, mutually
agreed upon by such Designated Holder and the requesting party beginning on the
effective date of such Registration Statement (except as part of such
registration). No Designated Holder of Registrable Securities subject to this
Section 6(a) shall be released from any obligation under any agreement,
arrangement or understanding entered into pursuant to this Section 6(a) unless
all other Designated Holders of Registrable Securities subject to the same
obligation are also released.

            (b) Restrictions on Public Sale by the Company. The Company agrees
not to effect any public sale or distribution of any of its securities, or any
securities convertible into or exchangeable or exercisable for such securities
(except pursuant to registrations on Form S-4 or S-8 or any successor thereto),
during the period beginning on the effective date of any Registration Statement
in which the Designated Holders of Registrable Securities are participating and
ending on the earlier of (i) the date on which all Registrable Securities
registered on such Registration Statement are sold and (ii) 120 days after the
effective date of such Registration Statement (except as part of such
registration).

        7. Registration Procedures.

            (a) Obligations of the Company. Whenever registration of Registrable
Securities has been requested pursuant to Section 3, Section 4 or Section 5 of
this Agreement, the Company shall use its commercially reasonable efforts to
effect the registration and sale of such Registrable Securities in accordance
with the intended method of distribution thereof as quickly as practicable, and
in connection with any such request, the Company shall, as expeditiously as
possible:

                (i) prepare and file with the Commission a Registration
Statement on any form for which the Company then qualifies or which counsel for
the Company shall deem appropriate and which form shall be available for the
sale of such Registrable Securities in accordance with the intended method of
distribution thereof, and cause such Registration Statement to become effective;
provided, however, that (x) before filing a Registration Statement or prospectus
or any amendments or supplements thereto, the Company shall provide counsel
selected by the Designated Holders holding a majority of the Registrable
Securities being registered in such registration ("Holders' Counsel") and any
other Inspector with an adequate and appropriate opportunity to review and
comment on such Registration Statement and each prospectus included therein (and
each amendment or supplement thereto) to be filed with the Commission, subject
to such documents being under the Company's control, and (y) the Company shall
notify the Holders' Counsel and each seller of Registrable Securities of any
stop order issued or threatened by the Commission and take all action required
to prevent the entry of such stop order or to remove it if entered;


                                       12
<PAGE>   16

                (ii) prepare and file with the Commission such amendments and
supplements to such Registration Statement and the prospectus used in connection
therewith as may be necessary to keep such Registration Statement effective for
the lesser of (x) 120 days and (y) such shorter period which will terminate when
all Registrable Securities covered by such Registration Statement have been
sold, and comply with the provisions of the Securities Act with respect to the
disposition of all securities covered by such Registration Statement during such
period in accordance with the intended methods of disposition by the sellers
thereof set forth in such Registration Statement;

                (iii) furnish to each seller of Registrable Securities, prior to
filing a Registration Statement, at least one copy of such Registration
Statement as is proposed to be filed, and thereafter such number of copies of
such Registration Statement, each amendment and supplement thereto (in each case
including all exhibits thereto), and the prospectus included in such
Registration Statement (including each preliminary prospectus) and any
prospectus filed under Rule 424 under the Securities Act as each such seller may
reasonably request in order to facilitate the disposition of the Registrable
Securities owned by such seller;

                (iv) register or qualify such Registrable Securities under such
other securities or "blue sky" laws of such jurisdictions as any seller of
Registrable Securities may request, and to continue such qualification in effect
in such jurisdiction for as long as permissible pursuant to the laws of such
jurisdiction, or for as long as any such seller requests or until all of such
Registrable Securities are sold, whichever is shortest, and do any and all other
acts and things which may be reasonably necessary or advisable to enable any
such seller to consummate the disposition in such jurisdictions of the
Registrable Securities owned by such seller; provided, however, that the Company
shall not be required to (x) qualify generally to do business in any
jurisdiction where it would not otherwise be required to qualify but for this
Section 7(a)(iv), (y) subject itself to taxation in any such jurisdiction or (z)
consent to general service of process in any such jurisdiction;

                (v) notify each seller of Registrable Securities at any time
when a prospectus relating thereto is required to be delivered under the
Securities Act, upon discovery that, or upon the happening of any event as a
result of which, the prospectus included in such Registration Statement contains
an untrue statement of a material fact or omits to state any material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading and the
Company shall promptly prepare a supplement or amendment to such prospectus and
furnish to each seller of Registrable Securities a reasonable number of copies
of such supplement to or an amendment of such prospectus as may be necessary so
that, after delivery to the purchasers of such Registrable Securities, such
prospectus shall not contain an untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading;

                (vi) enter into and perform customary agreements (including an
underwriting agreement in form requested by the Approved Underwriter or Company
Underwriter, if any, selected as provided in Section 3, Section 4 or Section 5,



                                       13
<PAGE>   17

as the case may be) and take such other actions as are prudent and reasonably
required in order to expedite or facilitate the disposition of such Registrable
Securities, including causing its officers to participate in "road shows" and
other information meetings organized by the Approved Underwriter or Company
Underwriter;

                (vii) make available at reasonable times for inspection by any
seller of Registrable Securities, any managing underwriter participating in any
disposition of such Registrable Securities pursuant to a Registration Statement,
Holders' Counsel and any attorney, accountant or other agent retained by any
such seller or any managing underwriter (each, an "Inspector" and collectively,
the "Inspectors"), all financial and other records, pertinent corporate
documents and properties of the Company and its subsidiaries (collectively, the
"Records") as shall be reasonably necessary to enable them to exercise their due
diligence responsibility, and cause the Company's and its subsidiaries'
officers, directors and employees, and the independent public accountants of the
Company, to supply all information reasonably requested by any such Inspector in
connection with such Registration Statement. Records that the Company
determines, in good faith, to be confidential and which it notifies the
Inspectors are confidential shall not be disclosed by the Inspectors (and the
Inspectors shall confirm their agreement in writing in advance to the Company if
the Company shall so request) unless (x) the disclosure of such Records is
necessary, in the Company's judgment, to avoid or correct a misstatement or
omission in the Registration Statement, (y) the release of such Records is
ordered pursuant to a subpoena or other order from a court of competent
jurisdiction after exhaustion of all appeals therefrom or (z) the information in
such Records was known to the Inspectors on a non-confidential basis prior to
its disclosure by the Company or has been made generally available to the
public. Each seller of Registrable Securities agrees that it shall, upon
learning that disclosure of such Records is sought in a court of competent
jurisdiction, give notice to the Company and allow the Company, at the Company's
expense, to undertake appropriate action to prevent disclosure of the Records
deemed confidential;

                (viii) if such sale is pursuant to an underwritten offering,
obtain a "cold comfort" letter dated the effective date of the Registration
Statement and the date of the closing under the underwriting agreement from the
Company's independent public accountants in customary form and covering such
matters of the type customarily covered by "cold comfort" letters as Holders'
Counsel or the managing underwriter reasonably requests;

                (ix) furnish, at the request of any seller of Registrable
Securities on the date such securities are delivered to the underwriters for
sale pursuant to such registration or, if such securities are not being sold
through underwriters, on the date the Registration Statement with respect to
such securities becomes effective, an opinion, dated such date, of counsel
representing the Company for the purposes of such registration, addressed to the
underwriters, if any, and to the seller making such request, covering such legal
matters with respect to the registration in respect of which such opinion is
being given as the underwriters, if any, and such seller may reasonably request
and are customarily included in such opinions;



                                       14
<PAGE>   18

                (x) comply with all applicable rules and regulations of the
Commission, and make available to its security holders, as soon as reasonably
practicable but no later than fifteen (15) months after the effective date of
the Registration Statement, an earnings statement covering a period of twelve
(12) months beginning after the effective date of the Registration Statement, in
a manner which satisfies the provisions of Section 11(a) of the Securities Act
and Rule 158 thereunder;

                (xi) cause all such Registrable Securities to be listed on each
securities exchange on which similar securities issued by the Company are then
listed, provided that the applicable listing requirements are satisfied;

                (xii) keep Holders' Counsel advised in writing as to the
initiation and progress of any registration under Section 3, Section 4 or
Section 5 hereunder;

                (xiii) cooperate with each seller of Registrable Securities and
each underwriter participating in the disposition of such Registrable Securities
and their respective counsel in connection with any filings required to be made
with the NASD; and

                (xiv) take all other steps reasonably necessary to effect the
registration of the Registrable Securities contemplated hereby.

            (b) Seller Information. The Company may require each seller of
Registrable Securities as to which any registration is being effected to
furnish, and such seller shall furnish, to the Company such information
regarding the distribution of such securities as the Company may from time to
time reasonably request in writing.

            (c) Notice to Discontinue. Each Designated Holder agrees that, upon
receipt of any notice from the Company of the happening of any event of the kind
described in Section 7(a)(v), such Designated Holder shall forthwith discontinue
disposition of Registrable Securities pursuant to the Registration Statement
covering such Registrable Securities until such Designated Holder's receipt of
the copies of the supplemented or amended prospectus contemplated by Section
7(a)(v) and, if so directed by the Company, such Designated Holder shall deliver
to the Company (at the Company's expense) all copies, other than permanent file
copies then in such Designated Holder's possession, of the prospectus covering
such Registrable Securities which is current at the time of receipt of such
notice. If the Company shall give any such notice, the Company shall extend the
period during which such Registration Statement shall be maintained effective
pursuant to this Agreement (including, without limitation, the period referred
to in Section 7(a)(ii)) by the number of days during the period from and
including the date of the giving of such notice pursuant to Section 7(a)(v) to
and including the date when sellers of such Registrable Securities under such
Registration Statement shall have received the copies of the supplemented or
amended prospectus contemplated by and meeting the requirements of Section
7(a)(v).


                                       15
<PAGE>   19

            (d) Registration Expenses. The Company shall pay all expenses
arising from or incident to its performance of, or compliance with, this
Agreement, including, without limitation, (i) Commission, stock exchange and
NASD registration and filing fees, (ii) all fees and expenses incurred in
complying with securities or "blue sky" laws (including reasonable fees, charges
and disbursements of counsel to any underwriter incurred in connection with
"blue sky" qualifications of the Registrable Securities as may be set forth in
any underwriting agreement), (iii) all printing, messenger and delivery
expenses, (iv) the fees, charges and expenses of one counsel to the Company and
of its independent public accountants and any other accounting fees, charges and
expenses incurred by the Company (including, without limitation, any expenses
arising from any "cold comfort" letters or any special audits incident to or
required by any registration or qualification) and, in the case of Demand
Registration or an S-3 Registration, any legal fees, charges and expenses of one
special counsel selected by the Initiating Holders or the S-3 Initiating
Holders, as the case may be, (v) any liability insurance or other premiums for
insurance obtained in connection with any Demand Registration or piggy-back
registration thereon, Incidental Registration or S-3 Registration pursuant to
the terms of this Agreement, regardless of whether such Registration Statement
is declared effective and (vi) fees and disbursements of underwriters, selling
brokers, dealers, managers and similar securities industry professionals
relating to distribution of Registrable Securities. All of the expenses
described in the preceding sentence of this Section 7(d) are referred to herein
as "Registration Expenses." The Designated Holders of Registrable Securities
sold pursuant to a Registration Statement shall bear the expense of any broker's
commission or underwriter's discount or commission relating to registration and
sale of such Designated Holders' Registrable Securities in proportion to the
number of Registrable Securities that each Designated Holder shall have
registered pursuant to such Registration Statement and, subject to clause (iv)
above, shall bear the fees and expenses of their own counsel.

        8. Indemnification; Contribution.

            (a) Indemnification by the Company. The Company agrees to indemnify
and hold harmless each Designated Holder, its partners, directors, officers,
affiliates and each Person who controls (within the meaning of Section 15 of the
Securities Act) such Designated Holder from and against any and all losses,
claims, damages, liabilities and expenses (including reasonable costs of
investigation) (each, a "Liability" and collectively, "Liabilities"), arising
out of or based upon any untrue, or allegedly untrue, statement of a material
fact contained in any Registration Statement, prospectus or preliminary
prospectus or notification or offering circular (as amended or supplemented if
the Company shall have furnished any amendments or supplements thereto) or
arising out of or based upon any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading under the circumstances such statements were made, except
insofar as such Liability arises out of or is based upon any untrue statement or
alleged untrue statement or omission or alleged omission contained in such
Registration Statement, preliminary prospectus or final prospectus in reliance
and in conformity with information concerning such Designated Holder furnished
in writing to the Company by such Designated Holder expressly for use therein,
including, without limitation, the


                                       16
<PAGE>   20

information furnished to the Company pursuant to Section 8(b). The Company shall
also provide customary indemnities to any underwriters of the Registrable
Securities, their officers, directors and employees and each Person who controls
such underwriters (within the meaning of Section 15 of the Securities Act) to
the same extent as provided above with respect to the indemnification of the
Designated Holders of Registrable Securities.

            (b) Indemnification by Designated Holders. In connection with any
Registration Statement in which a Designated Holder is participating pursuant to
Section 3, Section 4 or Section 5 hereof, each such Designated Holder shall
promptly furnish to the Company in writing such information with respect to such
Designated Holder as the Company may reasonably request or as may be required by
law for use in connection with any such Registration Statement or prospectus and
all information required to be disclosed in order to make the information
previously furnished to the Company by such Designated Holder not materially
misleading or necessary to cause such Registration Statement not to omit a
material fact with respect to such Designated Holder necessary in order to make
the statements therein not misleading. Each Designated Holder agrees to
indemnify and hold harmless the Company, any underwriter retained by the Company
and each Person who controls the Company or such underwriter (within the meaning
of Section 15 of the Securities Act) to the same extent as the foregoing
indemnity from the Company to the Designated Holders, but only if such statement
or alleged statement or omission or alleged omission was made in reliance upon
and in conformity with information with respect to such Designated Holder
furnished in writing to the Company by such Designated Holder expressly for use
in such Registration Statement or prospectus, including, without limitation, the
information furnished to the Company pursuant to this Section 8(b); provided,
however, that the total amount to be indemnified by such Designated Holder
pursuant to this Section 8(b) shall be limited to the net proceeds received by
such Designated Holder in the offering to which the Registration Statement or
prospectus relates.

            (c) Conduct of Indemnification Proceedings. Any Person entitled to
indemnification hereunder (the "Indemnified Party") agrees to give prompt
written notice to the indemnifying party (the "Indemnifying Party") after the
receipt by the Indemnified Party of any written notice of the commencement of
any action, suit, proceeding or investigation or threat thereof made in writing
for which the Indemnified Party intends to claim indemnification or contribution
pursuant to this Agreement; provided, however, that the failure so to notify the
Indemnifying Party shall not relieve the Indemnifying Party of any Liability
that it may have to the Indemnified Party hereunder (except to the extent that
the Indemnifying Party is materially prejudiced or otherwise forfeits
substantive rights or defenses by reason of such failure). If notice of
commencement of any such action is given to the Indemnifying Party as above
provided, the Indemnifying Party shall be entitled to participate in and, to the
extent it may wish, jointly with any other Indemnifying Party similarly
notified, to assume the defense of such action at its own expense, with counsel
chosen by it and reasonably satisfactory to such Indemnified Party. The
Indemnified Party shall have the right to employ separate counsel in any such
action and participate in the defense thereof, but the fees and expenses of such
counsel shall be paid by the Indemnified Party unless (i) the Indemnifying Party
agrees to pay the same, (ii) the Indemnifying Party fails to assume


                                       17
<PAGE>   21

the defense of such action with counsel reasonably satisfactory to the
Indemnified Party or (iii) the named parties to any such action (including any
impleaded parties) include both the Indemnifying Party and the Indemnified Party
and such parties have been advised by such counsel that either (x)
representation of such Indemnified Party and the Indemnifying Party by the same
counsel would be inappropriate under applicable standards of professional
conduct or (y) there may be one or more legal defenses available to the
Indemnified Party which are different from or additional to those available to
the Indemnifying Party. In any of such cases, the Indemnifying Party shall not
have the right to assume the defense of such action on behalf of such
Indemnified Party, it being understood, however, that the Indemnifying Party
shall not be liable for the fees and expenses of more than one separate firm of
attorneys (in addition to any local counsel) for all Indemnified Parties. No
Indemnifying Party shall be liable for any settlement entered into without its
written consent, which consent shall not be unreasonably withheld. No
Indemnifying Party shall, without the consent of such Indemnified Party, effect
any settlement of any pending or threatened proceeding in respect of which such
Indemnified Party is a party and indemnity has been sought hereunder by such
Indemnified Party, unless such settlement includes an unconditional release of
such Indemnified Party from all liability for claims that are the subject matter
of such proceeding.

            (d) Contribution. If the indemnification provided for in this
Section 8 from the Indemnifying Party is unavailable to an Indemnified Party
hereunder in respect of any Liabilities referred to herein, then the
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such Liabilities in such proportion as is appropriate to reflect the relative
fault of the Indemnifying Party and Indemnified Party in connection with the
actions which resulted in such Liabilities, as well as any other relevant
equitable considerations. The relative faults of such Indemnifying Party and
Indemnified Party shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue statement
of a material fact or omission or alleged omission to state a material fact, has
been made by, or relates to information supplied by, such Indemnifying Party or
Indemnified Party, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action. The amount paid
or payable by a party as a result of the Liabilities referred to above shall be
deemed to include, subject to the limitations set forth in Sections 8(a), 8(b)
and 8(c), any legal or other fees, charges or expenses reasonably incurred by
such party in connection with any investigation or proceeding; provided that the
total amount to be contributed by such Designated Holder shall be limited to the
net proceeds received by such Designated Holder in the offering.

            The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 8(d) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

        9. Rule 144. The Company covenants that it shall (a) file any reports
required to be filed by it under the Exchange Act and (b) take such further
action as each Designated Holder may reasonably request (including providing any
information necessary to comply with Rule 144 under the Securities Act), all to
the extent required from time to time to enable such Designated Holder to sell
Registrable Securities without registration under the Securities Act within the
limitation of the exemptions provided by (i) Rule 144 under the Securities Act,
as such rule may be amended from time to time, or Regulation S under the
Securities Act or (ii) any similar rules or regulations hereafter adopted by the
Commission. The Company shall, upon the request of any Designated Holder,
deliver to such Designated Holder a written statement as to whether it has
complied with such requirements.

        10. Miscellaneous.

            (a) Recapitalizations, Exchanges, etc. The provisions of this
Agreement shall apply to the full extent set forth herein with respect to (i)
the shares of Common Stock, (ii) any and all shares of voting common stock of
the Company into which the shares of Common Stock are converted, exchanged or
substituted in any recapitalization or other capital reorganization by the
Company and (iii) any and all equity securities of the Company or any successor
or assign of the Company (whether by merger, consolidation, sale of assets or
otherwise) which may be issued in respect of, in conversion of, in exchange for
or in substitution of, the shares of Common Stock and shall be appropriately
adjusted for any stock dividends, splits, reverse splits, combinations,
recapitalizations and the like occurring after the date hereof. The Company
shall cause any successor or assign (whether by merger, consolidation, sale of
assets or otherwise) to enter into a new registration rights agreement with the
Designated Holders on terms substantially the same as this Agreement as a
condition of any such transaction.

            (b) No Inconsistent Agreements. Except for the Fifth Amended and
Restated Investor Rights Agreement, the Company represents and warrants that it
has not granted to any Person the right to request or require the Company to
register any securities issued by the Company, other than the rights granted to
the Designated Holders herein. The Company shall not enter into any agreement
with respect to its securities that is inconsistent with the rights granted to
the Designated Holders in this Agreement or grant any additional registration
rights to any Person or with respect to any securities which are not Registrable
Securities which are prior in right to or inconsistent with the rights granted
in this Agreement; provided that the Company may grant to Sports Capital (as
defined in the Stock Purchase Agreement) registration rights similar to those
held by the Major Stockholders pursuant to this Agreement.

            (c) Remedies. The Designated Holders, in addition to being entitled
to exercise all rights granted by law, including recovery of damages, shall be
entitled to specific performance of their rights under this Agreement. The
Company agrees that monetary damages would not be adequate compensation for any
loss incurred by reason of a breach by it of the provisions of this Agreement
and hereby agrees to waive in any action for specific performance the defense
that a remedy at law would be adequate.

            (d) Amendments and Waivers. Except as otherwise provided herein, the
provisions of this Agreement may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given
unless consented to in writing by each of (i) the Company, (ii) the General
Atlantic Stockholders and (iii) ICP; provided, however, that any such amendment,
modification, supplement or waiver that adversely affects any Major Stockholder
(except ICP) in a manner different than any other Designated Holder shall
require the written consent of such adversely affected Major Stockholder;
provided, further, that the Company may add Sports Capital (as defined in the
Stock Purchase Agreement) as a party to this Agreement as a Major Stockholder
without the consent of the General Atlantic Stockholders, ICP or the Major
Stockholders. Any such written consent shall be binding upon the Company and all
of the Designated Holders.
