<Page>

or successor form registration filed with the Commission (a "FORM S-1").
Notwithstanding the foregoing, the Corporation agrees to undertake up to two (2)

"short-form" registration at any time following the date which is six (6) months

       Subject to the foregoing provisions, the Corporation shall file a
registration statement covering the Registrable Securities and Company
Securities (if any) so requested or otherwise elected to be registered as soon

       (c)    UNDERWRITING. If the Initiating Holders intend to distribute the
Registrable Securities covered by their request by means of an underwriting,
they shall so advise the Corporation as a part of their request made pursuant to
Section 3.1(b) and the Corporation shall include such information in the written
notice referred to in Section 3.1(b)(i). In such event, the right of any Holder
or the Corporation to registration pursuant to Section 3.1 shall be conditioned
upon the participation of such Holder or the Corporation, as the case may be, in
such underwriting and the inclusion of such Holder's Registrable Securities (or
the Company Securities) in the underwriting to the extent provided herein. The
Corporation shall (together with all Holders proposing to distribute their
Securities through such underwriting) 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; provided, that
such underwriters shall each be a nationally recognized and reputable investment
banking firm. Notwithstanding any other provision of this Section 3.1, if the
managing underwriter advises the Initiating Holders in writing that marketing
factors indicate that an underwriting of Registrable Securities would not be
successful at such time or require a limitation of the number of shares to be
underwritten, then the Initiating Holders shall so advise the Corporation and
all Holders of Registrable Securities which would otherwise be registered and
underwritten pursuant hereto, and the number of shares included in the
registration and underwriting, if any, shall be allocated, first by reducing
(and finally eliminating, if necessary) the Company Securities to be included in
such underwriting, and second, by allocating among the Holders of Registrable
Securities requesting registration in proportion, as nearly as practicable, to
the total number of Registrable Securities held by such Holders at the time of
filing of the registration statement; PROVIDED, that the Corporation shall not
proceed with any registration pursuant to this Section 3.1 of fewer than the
minimum number of Registrable Securities required to commence such registration
pursuant to Section 3.1(b); PROVIDED, FURTHER that no registration so
discontinued shall diminish the number of registrations to which the Holders are
entitled pursuant to this Section 3.1. If any Holder

                                       10
<Page>

or the Corporation disapproves of the terms of the underwriting, it may elect to
withdraw therefrom by written notice to the Corporation (in the case of a
withdrawal by a Holder), the underwriters and the Initiating Holders. Any
Registrable Securities withdrawn from such underwriting shall not be included in
such registration.

       3.2    COMPANY REGISTRATION.

       (a)    NOTICE OF REGISTRATION. If at any time or from time to time after
the date of this Agreement, the Corporation shall determine to register any of
its Securities in connection with the public offering of such Securities for
cash, for its own account or for the account of a third party (other than a
registration relating solely to employee stock option or purchase plans or
relating solely to a Rule 145 transaction), the Corporation will:

              (i)     promptly give to each Holder written notice thereof; and

              (ii)    include in such registration (and any related
qualification under blue sky laws or other compliance), and in any underwriting
involved therein, all the Registrable Securities specified in a written request
or requests, made within thirty (30) days after receipt of such written notice
from the Corporation, by any Holder or Holders, except as set forth in Section
3.2(b) below.

       (b)    UNDERWRITING. If the registration of which the Corporation gives
notice is for a registered public offering involving an underwriting, the
Corporation shall so advise the Holders as a part of the written notice given
pursuant to Section 3.2(a)(i). In such event the right of any Holder to
registration pursuant to Section 3.2 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein. All
Holders proposing to distribute their Securities through such underwriting shall
(together with the Corporation and other holders distributing their Securities
through such underwriting) enter into an underwriting agreement in customary
form with the underwriter or underwriters selected for such underwriting by the
Corporation. Notwithstanding any other provision of this Section 3.2, if the
managing underwriter determines that marketing factors require a limitation of
the number of shares to be underwritten, the underwriter may limit the number of
Registrable Securities to be included in the registration and underwriting on a
pro rata basis based on the total number of the Registrable Securities held by
the Holders, PROVIDED, that no such reduction shall be made with respect to
Securities being offered by the Corporation in connection with the offering of
such Securities for its own account; PROVIDED, FURTHER, that all other shares of
Common Stock held by all parties, other than the Holders, shall be excluded
before the exclusion of any shares of Registrable Securities held by the Holders
who desire to have their shares included in the registration and offering. The
Corporation shall advise all Holders of Registrable Securities which would
otherwise be registered and underwritten pursuant hereto of any such
limitations, and the number of shares of Registrable Securities that may be
included in the registration. If any Holder disapproves of the terms of any such
underwriting, he may elect to withdraw therefrom by written notice to the
Corporation and the underwriter. Any Registrable Securities excluded or
withdrawn from such underwriting shall not be included in such registration.

       (c)    Notwithstanding anything to the contrary in this Section 3.2, the
Corporation shall not be obligated to effect any registration of Registrable
Securities under this Section 3.2 pursuant to a

                                       11
<Page>

registration statement covering any of its Securities to be issued in connection
with mergers, acquisitions, exchange offers, dividend reinvestment plans or
stock option or other employee benefit plans.

       3.3    S-3 REGISTRATIONS. If, at any time or from time to time after the
Corporation is eligible under applicable Commission rules to use a Form S-3 or
equivalent "short-form" registration (a "FORM S-3") of its Securities, the
Corporation is requested in writing by any Holder of the Registrable Securities
then outstanding to undertake a registration (including, without limitation, by
means of a shelf registration pursuant to Rule 415 under the Securities Act if
the Corporation is then eligible to use such a registration), the Corporation
shall promptly give notice of such proposed registration to all Holders of
Registrable Securities and such Holders shall have twenty (20) days to include
their shares of Registrable Securities in such registration request. The
Corporation shall file, as expeditiously as possible, but in no event more than
forty-five (45) days after such twentieth date (20th) date, a registration
statement on Form S-3 (a "S-3 REGISTRATION STATEMENT") of the Registrable
Securities which the Corporation has been requested to register and thereafter
shall use its best efforts to obtain effectiveness of such S-3 Registration
Statement as soon as practicable. Notwithstanding the foregoing (i) the
Corporation shall not be required to effect any registration hereunder unless
the number of shares of Registrable Securities which Holders have requested to
be included in such registration would result in an anticipated aggregate
offering price of more than $2,000,000 (net of underwriting discounts and
commissions), (ii) the Corporation shall not be obligated to take any action to
effect more than four (4) such registrations pursuant to this Section 3.3 in any
twelve-month period and (iii) the Corporation shall have the right to defer any
such requested registration once in any twelve-month period, for a period of up
to forty-five (45) days, if in the opinion of the Board, it would be seriously
detrimental to the Corporation for a registration statement to be filed. The
Corporation shall use its best efforts to keep any shelf registration statement
continuously effective for a period until all of the Registrable Securities
registered thereunder become eligible for resale without volume restrictions
pursuant to Rule 144 under the Securities Act (such period being called the
"SHELF REGISTRATION PERIOD"). Notwithstanding the foregoing, if in the opinion
of the Board, it would be seriously detrimental to maintain the effectiveness of
any shelf registration statement, the Corporation may allow such shelf
registration statement to fail to be effective or the prospectus contained
therein to be unusable as a result of such nondisclosure for up to sixty (60)
days in any twelve-month period during the Shelf Registration Period. The
Corporation may include in the registration under this Section 3.3 any other
shares of Common Stock so long as the inclusion in such registration of such
shares will not, in the opinion of the managing underwriter, if any, interfere
with the successful marketing in accordance with the intended method of sale or
other disposition of all the shares of Registrable Securities sought to be
registered by the Holder or Holders of Registrable Securities pursuant to this
Section 3.3. If it is determined as provided above that there will be such
interference, the other shares of Common Stock sought to be included by the
Corporation shall be excluded to the extent deemed appropriate by the managing
underwriter, if any, and all other shares of Common Stock held by other parties
shall be excluded before the exclusion of any shares of Registrable Securities
held by the Holders who desire to have their shares included in the registration
and offering. If, as contemplated above, and after excluding all other shares of
Common Stock held by parties, other than the Holders, shares of the Registrable
Securities of the Holders are to be excluded, the number of shares of
Registrable Securities of each participating Holder which are to be included
shall be proportionate, as nearly as practicable, to the number of shares
included for the other participating Holders, based upon the total

                                       12
<Page>

number of the Registrable Securities held by such Holders at the time of filing
of the registration statement.

       3.4    EXPENSES OF REGISTRATION.

       (a)    All expenses incurred in connection with any registration pursuant
to the registrations under Sections 3.1, 3.2 and 3.3, including, without
limitation, all registration, filing and qualification fees, printing expenses,
fees and disbursements of counsel for the Corporation, expenses of complying
with state securities or "blue sky" laws (including fees of counsel for the
Corporation and counsel for the underwriters), accountants' fees and expenses
incident to or required by any such registration, expenses incident to the
listing of Securities on any exchange in which the Registrable Securities have
been listed, any filings required to be made with the NASD, expenses incident to
any special audits incidental to or required by such registration and the
reasonable fees and disbursements of one counsel designated in writing by a
majority of the Holders of Registrable Securities covered by such registration
shall be borne by the Corporation (although this provision will not prohibit any
other counsel to any Holder of Registrable Securities covered by such
registration from reviewing and commenting on any registration statement,
prospectus and all amendments or supplements thereto); PROVIDED, HOWEVER, the
Corporation shall not be required to pay for expenses of any registration
proceeding begun pursuant to Section 3.1, the request of which has been
subsequently withdrawn by the Initiating Holders, in which case, such expenses
shall be borne by the Holders of Securities (including Registrable Securities)
requesting or causing such withdrawal; provided that such Holders shall not be
required to pay (a) for the cost of normal audits of the Corporation and its
consolidated Subsidiaries that would have been performed in any event, and (b)
for the time of any executives or other personnel of the Corporation and its
Subsidiaries involved in the preparation of the registration statement and in
participating in road shows or any other presentations; and PROVIDED FURTHER,
HOWEVER, that if at the time of such withdrawal, the Holders have learned of a
material adverse change in the condition, business, or prospects of the
Corporation from that known to the Holders at the time of their request, then
the Holders shall not be required to pay any of such expenses and shall retain
their rights pursuant to Section 3.1.

       (b)    Notwithstanding anything to the contrary elsewhere in this
Agreement, all underwriters' discounts, commissions, or applicable stock
transfer and documentary stamp taxes (if any) relating to any particular sale of
Registrable Securities shall be borne by the seller of such Registrable
Securities in all cases.

       3.5    REGISTRATION PROCEDURES.

       (a)    In the case of each registration effected by the Corporation
pursuant to Section 3.2, the Corporation will keep each Holder participating
therein advised in writing as to the initiation of each registration and as to
the completion thereof. At its expense (except as otherwise provided in Section
3.4 above), the Corporation will:

              (i)     subject to paragraph 3.5(b), keep such registration
pursuant to Section 3.1, 3.2, or 3.3 effective for a period of two hundred
seventy (270) days to the extent such registration is made pursuant to Form S-3
(or any successor form) and for a period of one hundred twenty (120)

                                       13
<Page>

days otherwise, or until the Holder or Holders have completed the distribution
described in the registration statement relating thereto, whichever first
occurs;

              (ii)    (A) furnish to the Holders of Registrable Securities to be
registered, one counsel designated in writing by a majority of the Holders of
Registrable Securities to be registered and any managing underwriters, copies of
all such documents proposed to be filed, which documents (other than those
incorporated by reference) will be subject to the review of such Holders covered
by such registration, such counsel and such managing underwriters; (B) furnish
to each Holder of Registrable Securities to be registered and such Holder's
counsel, copies of all documents proposed to be filed in connection with such
registration either before or promptly after such filing; (C) cause its officers
and directors, counsel and independent certified public accountants to respond
to such inquiries as shall be necessary, in the reasonable opinion of counsel to
such Holders and such underwriters, to conduct a reasonable investigation within
the meaning of the Securities Act; and (D) consider in good faith any comments
or objection from counsel to such Holders as to the form or content of each
registration statement, prospectus and all amendments and supplements thereto or
any request for the acceleration of the effectiveness of each registration
statement, prospectus and all amendments or supplements thereto;

              (iii)   promptly notify each Holder (A) when a prospectus or any
prospectus supplement and each amendment thereto has been filed, and, with
respect to the registration statement and each amendment (including
post-effective amendments) and supplements thereto has been declared effective
by the Commission, (B) of any request by the Commission or any other federal or
state governmental authority during the period of effectiveness of the
registration statement for amendments or supplements to the registration
statement or related prospectus or for additional information relating to the
registration statement, (C) of the issuance by the Commission or any other
federal or state governmental authority of any stop order suspending the
effectiveness of the registration statement or the initiation of any proceedings
for that purpose, (D) of the receipt by the Corporation of any notification with
respect to the suspension of the qualification or exemption from qualification
of any of the Registrable Securities for sale in any jurisdiction or the
initiation of any proceeding for such purpose, or (E) of the happening of any
event which makes any statement made in the registration statement or related
prospectus or any document incorporated or deemed to be incorporated therein by
reference untrue in any material respect or which requires the making of any
changes in the registration statement or prospectus so that, in the case of the
registration statement, it will not contain any 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 not misleading, and that in the case of
the prospectus, it will not contain any 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 the light of the circumstances under which they
were made, not misleading;

              (iv)    use its best efforts to (A) cause all such Registrable
Securities registered pursuant hereunder to be listed on each securities
exchange on which similar Securities issued by the Corporation are then listed,
if any, or (B) secure designation and quotation of all the Registrable
Securities on the Nasdaq National Market, if then quoted thereon;

                                       14
<Page>

              (v)     provide a transfer agent and registrar for all Registrable
Securities registered pursuant hereunder and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such
registration;

              (vi)    use its best efforts to furnish, on the date that such
Registrable Securities are delivered to the underwriters for sale, if such
Registrable Securities are being sold through underwriters, (A) an opinion,
dated as of such date, of the counsel representing the Corporation 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
the Holders of a majority of the Registrable Securities covered by such
registration, addressed to the underwriters, if any, and to such Holders and (B)
a "comfort" letter dated as of such date and a "comfort" letter dated as of the
effective date of the registration statement, from the independent certified
public accountants of the Corporation, in form and substance as is customarily
given by independent certified public accountants to underwriters in an
underwritten public offering, addressed to the underwriters, if any, and if
permitted by applicable accounting standards, to such Holders;

              (vii)   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;

              (viii)  use its best efforts to promptly register and qualify the
resale of Registrable Securities covered by such registration statement under
such other securities or blue sky laws of all applicable jurisdictions in the
United States as any Holder of Registrable Securities reasonably requests in
writing; PROVIDED that the Corporation 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,
except in such jurisdiction where the Corporation is subject to service of
process;

              (ix)    otherwise use its best efforts to comply with all
applicable rules and regulations of the Commission, and make available to its
security holders, as soon as reasonably practicable, an earnings statement
covering the period of at least twelve (12) months, but not more than eighteen
(18) months, beginning with the first month after the effective date of the
registration statement, which earnings statement shall meet the requirements of
the Securities Act; and

              (x)     cooperate with each Holder of Registrable Securities
covered by any registration statement, and assist in any filings required to be
made with the NASD and in the performance of any due diligence investigation by
any underwriter (including any "qualified independent underwriter") that is
required to be retained in accordance with the rules and regulations of the
NASD.

       (b)    The Corporation may, upon the happening of any event (x) of the
kind described in clauses (B), (C), (D), or (E) of Section 3.5(a)(iii) or (y)
that, in the good faith judgment of the Board, renders it advisable to suspend
use of the prospectus due to pending corporate developments, public filings with
the Commission or similar events, suspend use of the prospectus on written
notice to each Holder for no more than forty-five (45) days in the aggregate in
any twelve-month period, in which case each Holder shall discontinue disposition
of Registrable Securities covered by the

                                       15
<Page>

registration statement or prospectus until copies of a supplemented or amended
prospectus are distributed to the Holders or until the Holders are advised in
writing by the Corporation that the use of the applicable prospectus may be
resumed. The Corporation shall use its best efforts to ensure that the use of
the prospectus may be resumed as soon as practicable. The Corporation shall use
its best efforts to obtain the withdrawal of any order suspending the
effectiveness of the registration statement, or the lifting of any suspension of
the qualification (or exemption from qualification) of any of the Securities for
sale in any jurisdiction, at the earliest practicable moment. As soon as is
practicable, the Corporation shall prepare a supplement or post-effective
amendment to the registration statement or a supplement to the related
prospectus or any document incorporated therein by reference or file any other
required document so that, as thereafter delivered to the purchasers of the
Registrable Securities being sold thereunder, such prospectus will not contain
an untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading.

       3.6    INDEMNIFICATION.

       (a)    To the extent permitted by law, the Corporation will indemnify and
hold harmless each Holder of Registrable Securities with respect to which a
registration has been effected pursuant to this Section 3, each of such Holders'
officers, directors and employees, and each Person who controls such Holder
(within the meaning of the Securities Act) and its officers, agents, directors,
representatives of and employees, and each underwriter, if any, and each Person
who controls any underwriter of the Registrable Securities held by or issuable
to such Holder, against all claims, losses, damages, costs, expenses and
liabilities whatsoever (or actions in respect thereof) arising out of or based
on any untrue statement (or alleged untrue statement) of a material fact
contained in any registration statement, preliminary or final prospectus
contained therein or any amendment or supplement thereto, offering circular or
other documents (including any related registration statement, notification or
the like) incident to any such registration, or based on 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, or any violation by
the Corporation of the Securities Act, Exchange Act or any state securities law
or of any rule or regulation promulgated under the Securities Act, Exchange Act
or any state securities law applicable to the Corporation and relating to action
or inaction required of the Corporation in connection with any such
registration, and will reimburse each such Holder, each of its officers,
directors, employees, and each Person who controls such Holder (within the
meaning of the Securities Act), each such underwriter and each Person who
controls any such underwriter (within the meaning of the Securities Act), for
any legal and any other expenses reasonably incurred in connection with
investigating or defending any such claim, loss, damage, cost, expense,
liability or action, PROVIDED that the Corporation will not be liable in any
such case to the extent that any such claim, loss, damage, cost, expense, or
liability arises out of or is based on any untrue statement or omission based
upon written information furnished to the Corporation in writing by any such
Holder and stated to be specifically for use therein.

       (b)    To the extent, but only to the extent, that there is an untrue
statement or omission made in a registration statement, prospectus, offering
circular or other document in reliance upon and in conformity with written
information furnished to the Corporation in writing by a Holder and stated to be
specifically for use therein, such Holder will, if Registrable Securities held
by or issuable

                                       16
<Page>

to such Holder are included in the Securities as to which such registration is
being effected, indemnify and hold harmless the Corporation, each of its
directors and officers who sign such registration statement, each underwriter,
if any, of the Corporation's Securities covered by such registration statement,
each Person who controls the Corporation (within the meaning of the Securities
Act), and each other Holder, each of such other Holder's officers, directors and
employees and each Person controlling such other Holder, against all claims,
losses, damages, costs, expenses and liabilities whatsoever (or actions in
respect thereof) arising out of or based on any such untrue statement of a
material fact contained in any such registration statement, preliminary or final
prospectus contained therein or any amendment or supplement thereto, offering
circular or other documents (including any related registration statement,
notification or the like) incident to any such registration, or based on any
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse the
Corporation, such other Holders, such directors, officers, employees, persons or
underwriters for any legal or any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage, cost,
expense, liability or action; PROVIDED, HOWEVER, such Holder's obligation to
indemnify shall be limited to the net amount of proceeds received by such Holder
from the sale of Registrable Securities pursuant to such registration statement.
The Corporation shall be entitled to receive from underwriters, selling brokers,
dealer managers and similar securities industry professionals participating in
the distribution of such Registrable Securities indemnification to the same
extent provided above in this Section 3.6(b) with respect to written information
furnished to the Corporation in writing by such Persons specifically provided
for any registration statement, prospectus, offering circular or other document.

       (c)    Each party entitled to indemnification under this Section 3.6 (the
"INDEMNIFIED PARTY") shall give notice to the party required to provide
indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be
withheld), and the Indemnified Party may participate in such defense at such
party's expense, and provided further that the Indemnifying Party shall, as a
condition to assuming the defense of such claim or litigation, acknowledge in
writing to the Indemnified Party that the Indemnifying Party assumes
responsibility for the indemnified claim or litigation, and provided further
that the failure of any Indemnified Party to give notice as provided herein
shall not relieve the Indemnifying Party of its obligations under this Section
3, to the extent such failure does not cause material prejudice.

       (d)    No Indemnified Party shall settle or compromise any such claim or
litigation without the written consent of the Indemnifying Party unless the
Indemnified Party agrees in writing to forego any and all claims for
indemnification from the Indemnifying Party with respect to such claim or
litigation. For the avoidance of doubt, if the Indemnified Party does settle or
compromise any such claim or litigation without the prior written consent of the
Indemnifying Party and does not agree in writing to forego any and all claims
for indemnification from the Indemnifying Party with respect to such claim or
litigation, such Indemnifying Party shall have no obligation whatsoever to
contribute to any amounts paid in such settlement. However, if the Indemnifying
Party, within a reasonable time, but in any event no more than thirty (30) days,
after notice of any such claim or

                                       17
<Page>

litigation, fails to assume the defense of such claim or litigation, including
by failing to employ counsel reasonably satisfactory to the Indemnified Party,
the Indemnified Party will have the right to undertake the defense, compromise
or settlement of such claim or litigation on behalf of, at the expense of, and
for the account and risk of the Indemnifying Party.

       (e)    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. If any such Indemnified Party shall have been advised by counsel
chosen by it that (i) there may be one or more legal defenses available to such
Indemnified Party which are different from or additional to those available to
the Indemnifying Party, or (ii) the use of counsel chosen by the Indemnifying
Party to represent the Indemnified Party would present such counsel with a
conflict of interest, then the Indemnifying Party shall not have the right to
assume the defense of such action on behalf of such Indemnified Party and will
promptly reimburse such Indemnified Party and any Person controlling such
Indemnified Party (within the meaning of the Securities Act) for the reasonable
fees and expenses of any counsel retained by the Indemnified Party, it being
understood that the Indemnifying Party shall not, in connection with any one
action or separate but similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys for
such Indemnified Party or controlling Person (within the meaning of the
Securities Act), which firm shall be designated in writing by the Indemnified
Party to the Indemnifying Party.

       (f)    The indemnification obligations of this Section 3.6 shall (i)
remain in full force and effect regardless of (A) any termination of this
Agreement, or (B) any investigation made by or on behalf of the Indemnified
Party, and (ii) shall survive any Transfer of the Registrable Securities made in
compliance with Section 4 of this Agreement.

       (g)    The indemnification required by this Section 3.6 shall be made by
periodic payments of the amount thereof during the course of the investigation
or the defense, as and when bills or invoices are received or indemnifiable
damages are incurred.

       (h)    The indemnification agreements contained in this Section 3.6 shall
be in addition to (i) any cause of action or similar right of Indemnified Party
against the Indemnifying Party or other Persons, and (ii) any liabilities the
Indemnifying Party may be subject to pursuant to the law.

       3.7    CONTRIBUTION. If the indemnification provided for in Section 3.6
is unavailable or insufficient to hold harmless an Indemnified Party thereunder,
then each Indemnifying Party thereunder shall contribute to the amount paid or
payable by such Indemnified Party as a result of the losses, claims, damages,
costs, expenses, liabilities or actions referred to in Section 3.6(a) or (b) in
such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party on the one hand and the Indemnified Party on the other in
connection with statements or omissions which resulted in such losses, claims,
damages or liabilities, as well as any other relevant equitable considerations.
The relative fault shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Indemnifying Party or the Indemnified Party and

                                       18
<Page>

the Parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such untrue statements or omission. The Parties hereto
agree that it would not be just and equitable if contributions pursuant to this
Section 3.7 were to be determined by pro rata or per capita allocation or by any
other method of allocation which does not take account of the equitable
considerations referred to in the first sentence of this Section 3.7. The amount
paid by an Indemnified Party as a result of the losses, claims, damages or
liabilities referred to in the first sentence of this Section 3.7 shall be
deemed to include any legal or other expenses reasonably incurred by such
Indemnified Party in connection with investigating or defending any action or
claim which is the subject of this Section 3.7. Promptly after receipt by an
Indemnified Party of notice of the commencement of any action against such party
in respect of which a claim for contribution may be made against an Indemnifying
Party under this Section 3.7, such Indemnified Party shall notify the
Indemnifying Party in writing of the commencement thereof if the notice
specified in Section 3.6(c) has not been given with respect to such action;
provided that the omission so to notify the Indemnifying Party shall not relieve
the Indemnifying Party from any liability which it may have to any Indemnified
Party otherwise under this Section 3.7, except to the extent that the
Indemnifying Party is materially prejudiced by such failure to give notice. The
Corporation and each Class B Common Stockholder agree with each other and shall
agree with the underwriters of the Registrable Securities, if requested by such
underwriters, that (a) the underwriters' portion of such contribution shall not
exceed the underwriting discount, commission and other compensation and (b)
except for the Corporation, the amount of such contribution shall not exceed the
net amount of proceeds received by such Indemnifying Party from the sale of
Securities in the offering to which the losses, claims, damages or liabilities
of the indemnified parties relate. 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.

       3.8    INFORMATION BY HOLDER. The Holder or Holders of Registrable
Securities included in any registration shall furnish to the Corporation such
information regarding such Holder or Holders and the distribution proposed by
such Holder or Holders as the Corporation may reasonably request in writing and
as shall be required in connection with any registration referred to in this
Section 3.

       3.9    RULE 144 REPORTING.

       (a)    With a view to making available to the Holders the benefits of
Rule 144 under the Securities Act or any other similar rule or regulation
hereafter adopted by the Commission that may at any time permit the Holders to
sell Registrable Securities to the public without registration ("RULE 144"), the
Corporation agrees to:

       (b)    make and keep public information available, as those terms are
understood and defined in Rule 144, at all times after ninety (90) days after
the effective date of the first registration filed by the Corporation which
involves a sale of Securities of the Corporation to the general public;

       (c)    file with the Commission in a timely manner all reports and other
documents required of the Corporation under the Securities Act and the Exchange
Act; and

       (d)    furnish to any Holder so long as such Holder owns any Registrable
Securities forthwith upon request a written statement by the Corporation that it
has complied with the reporting

                                       19
<Page>

requirements of said Rule 144 (at any time after ninety (90) days after the
effective date of said first registration statement filed by the Corporation),
and of the Securities Act and the Exchange Act (at any time after it has become
subject to such reporting requirements), a copy of the most recent annual or
quarterly report of the Corporation, and such other reports and documents so
filed by the Corporation as may be reasonably requested in availing any Holder
of any rule or regulation of the Commission permitting the selling of any such
Securities without registration.

       3.10   TERMINATION OF REGISTRATION RIGHTS; LOCK-UP AGREEMENT. All
registration rights provided hereunder shall terminate with respect to any
Holder at such time as such Holder is able to sell all of its Registrable
Securities under Rule 144 during any one three-month period (treating for these
purposes a Holder and its Affiliated transferees as one Holder). In
consideration for the Corporation agreeing to its obligations under this
Agreement, each Holder of Registrable Securities agrees and each transferee as
an unwaivable condition of Transfer shall agree that, until three (3) years
after the date of this Agreement, if requested in writing by the Corporation or
the managing underwriter of any underwritten registration, such Holder (or any
such transferee), if it then has Deemed Ownership of 5% or more of the then
Corporate Capitalization, will not effect any public sale or distribution,
including the making of any demand or request for registration during such
period under this Agreement or otherwise, or any sale pursuant to Rule 144 under
the Securities Act, of any Registrable Securities, or of any other Security of
the Corporation or of any Security convertible into or exchangeable or
exercisable for any Security of the Corporation (other than as part of such
underwritten public offering) during the time period reasonably requested by the
managing underwriter, not to exceed 75 days, or in the case of a Qualified IPO,
180 days (and the Corporation hereby also so agrees (except that the Corporation
may effect any sale or distribution of any such Securities pursuant to a
registration on Form S-4 or Form S-8, or any successor or similar form which is
then in effect or upon the conversion, exercise or exchange of any outstanding
Securities). The Corporation agrees to use its best efforts to cause (i) each
director and executive officer and (ii) each holder who has purchased Securities
from the Corporation at any time other than in a public offering and has Deemed
Ownership of 5% or more of the then Corporate Capitalization not to effect any
public sale or distribution, including the making of any demand or request for
registration during such period under this Agreement or otherwise, or any sale
pursuant to Rule 144 under the Securities Act, of any Registrable Securities, or
of any other Security of the Corporation or of any Security convertible into or
exchangeable or exercisable for any Security of the Corporation (other than as
part of such underwritten public offering) during the time period reasonably
requested by the managing underwriter, not to exceed 75 days, or in the case of
a Qualified IPO, 180 days. Each Holder agrees that the Corporation may instruct
its transfer agent to place stop transfer notations in its records to enforce
the provisions hereof.

       3.11   FUTURE GRANTS OF REGISTRATION RIGHTS. The Corporation agrees for
the benefit of the Holders that it will not, without the prior written consent
of the Holders of two-thirds of the then Registrable Securities, grant
registration rights with respect to any of its Securities upon terms more
favorable in any respect to the holders of such Securities than those contained
in this Section 3 or that conflict in any respect with the provisions applicable
to the Holders of Registrable Securities under this Section 3.

       3.12   PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No Person may
participate in any registration hereunder which is underwritten unless such
Person (a) agrees to sell its Securities on

                                       20
<Page>

the basis provided in any underwriting arrangements approved by such Person or
Persons entitled hereunder to approve such arrangements or (in the case of a
primary registration on behalf of the Corporation) the Corporation and (b)
completes and executes all questionnaires, powers of attorney, custody
agreements, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.

       3.13   AMENDMENTS TO SECTION 3. Notwithstanding anything to the contrary
contained herein, any term of this Section 3 may only be amended or waived with
the written consent of the Holders of two-thirds of the then Registrable
Securities; or, in the case of a waiver, by the party against whom enforcement
of any such waiver is sought. No waiver of any default with respect to any
provision, condition or requirement of this Section 3 shall be deemed to be a
continuing waiver in the future or a waiver of any other provision, condition or
requirement hereof, nor shall any delay or omission of either party to exercise
any right hereunder in any manner impair the exercise of any such right accruing
to it thereafter. Notwithstanding the foregoing, no such amendment shall be
effective to the extent that it applies to less than all of the Holders and
adversely affects the Holders it does not apply to, unless the Holder(s)
adversely affected by such discrimination consent in writing. The Corporation
shall not offer or pay any consideration to a Holder for consenting to such an
amendment or waiver unless the same consideration is offered to each Holder and
the same consideration is paid to each Holder which consents to such amendment
or waiver.

       3.14   TRANSFER OF REGISTRATION RIGHTS.

       The rights of each Holder of Registrable Securities under this Section 3,
including without limitation, the right to have the Corporation register its
Registrable Securities in accordance with this Section 3, shall not be
assignable by the Holder thereof except together with the Registrable Security
(a) in a Qualified Transfer of such Registrable Security or (b) in a Transfer of
such Registrable Security to another Class B Common Stockholder in compliance
with Section 4 of this Agreement.

SECTION 4.    RIGHTS OF FIRST REFUSAL; DESIGNATION OF PURCHASER OR REDEMPTION.

       4.1    TRANSFER RESTRICTIONS. In the event of the receipt by a Class B
Common Stockholder of an offer (an "OFFER") for the purchase of all or any part
of its Securities of the Corporation (the "OFFERED STOCK"), which Offer was made
by another Class B Common Stockholder other than in connection with a registered
offering of such Securities for the benefit of the transferor pursuant to which
the subject shares will convert to Class A Common Stock, the following
procedures shall be complied with by such Class B Common Stockholder (in each
such case, the "SELLING CLASS B COMMON STOCKHOLDER"), the Acquiring Class B
Stockholders and the Corporation:

       (a)    The Selling Class B Common Stockholder shall give to the
Corporation and each of the other Class B Common Stockholders a true and correct
copy of such Offer and a written notice (the "OFFER NOTICE") setting out the
full details of such Offer, which Offer Notice shall specify the name of the
offeror, the number of shares or percentage of Securities covered by the Offer,
the date upon which the time periods during which the Acquiring Class B Common
Stockholders may exercise the right of first refusal as set forth herein will
expire, the terms of payment, whether for cash, credit, property or services,
and if on credit, the time and interest rate, as well as any and all other
consideration being received or paid in connection with such proposed
transaction, the expected date of consummation of the transaction, and all other
material terms, conditions and

                                       21
<Page>

details of such Offer. The Class B Common Stockholders entitled to receive an
Offer Notice pursuant to this Section 4.1(a) are hereinafter referred to
collectively as the "ACQUIRING CLASS B COMMON STOCKHOLDERS", and each
individually as an Acquiring Class B Common Stockholder.

       (b)    Upon receipt of such written Offer, if any, and Offer Notice, the
Acquiring Class B Common Stockholders shall have the exclusive right and option,
exercisable at any time during a period of forty-five (45) days from the date of
delivery of the Offer Notice to the Acquiring Class B Common Stockholders (the
"NOTICE DATE"), to purchase, and the Selling Class B Common Stockholder shall be
obligated to sell, all or, subject to Section 4.1(d), any part of the Offered
Stock at the same price per share, on the same terms and conditions and at the
time set forth in the Offer and Offer Notice; PROVIDED, HOWEVER, that in the
event that the Offer and Offer Notice state that the purchase price for the
Offered Stock is to be paid in whole or in part in consideration other than
cash, any Acquiring Class B Common Stockholder may request the Board, by the
vote or approval of a majority of the Board (excluding from such calculation any
Class B Director elected by the Selling Class B Common Stockholder or its
Affiliates), to select an independent nationally recognized and reputable
investment banker to determine the fair market value of such non-cash
consideration that the Acquiring Class B Common Stockholder desires to pay in
cash and the Acquiring Class B Common Stockholders may elect to purchase such
Offered Stock by the payment of cash in an amount equal to such fair market
value. Any such determination of fair market value made pursuant to the
preceding sentence shall be binding on the Selling Class B Common Stockholder
and the Acquiring Class B Common Stockholders absent fraud or bad faith. Each
Acquiring Class B Common Stockholder shall have the right to acquire a pro rata
portion of such Offered Stock based upon the Deemed Ownership of such Class B
Common Stockholder in proportion to the Deemed Ownership of all Class B Common
Stockholders (other than the Selling Class B Common Stockholder) or, at the
option of the Acquiring Class B Common Stockholder, any lesser amount. In the
event that any Acquiring Class B Common Stockholder requests a third party
valuation of any non-cash consideration or the Board seeks an independent third
party valuation in connection with its determination of the fair market value of
the Offered Stock, in each case under this Section 4.1(b) the fees and expenses
of any such independent third party shall be shared equally among the Selling
Class B Common Stockholder, the Corporation and the Acquiring Class B Common
Stockholders.

       (c)    Each Class B Common Stockholder shall notify the Corporation in
writing within thirty (30) days of the Notice Date (or within forty-five (45)
days if the Board has voted to complete an appraisal of fair market value
pursuant to Section 4.1(b) above) of its election to purchase all or any part of
its pro rata share of the Offered Stock, as applicable. Any Class B Common
Stockholder who does not deliver such notification within the specified period
shall be deemed to have elected not to purchase any of the Offered Stock. If any
Class B Common Stockholder does not elect to purchase its full pro rata portion
of the Offered Stock, the Corporation shall so notify the Acquiring Class B
Common Stockholders electing to purchase any of the Offered Stock in writing
within five (5) days after expiration of the notice period (the "REFUSAL
NOTICE"). Such Acquiring Class B Common Stockholders may, by written notice
delivered to the Corporation within fifteen (15) days of the date of the Refusal
Notice (the "ELECTION PERIOD"), elect to purchase up to the balance of the
Offered Stock. If as a result of such elections, the number of shares of Offered
Stock which such Acquiring Class B Common Stockholders have elected to purchase
exceeds the full amount of the Offered Stock, as applicable, the number of
shares of Offered Stock that each such Acquiring Class

                                       22
<Page>

B Common Stockholder is entitled to purchase shall be cut back on a pro rata
basis in accordance with its pro rata Deemed Ownership.

       (d)    If the Acquiring Class B Common Stockholders do not fully exercise
their rights to purchase the Offered Stock, the Board may elect, upon the
approval of a majority of the Directors (excluding from such calculation any
Class B Director elected by the Selling Class B Common Stockholder or its
Affiliates), to have the Corporation redeem the Offered Stock; PROVIDED, that
under no circumstances shall the Board be obligated to approve such redemption.
In the event that the Board elects to have the Corporation redeem the Offered
Stock, the redemption will be at the price and on the terms on which an
Acquiring Class B Common Stockholder would have been entitled to purchase such
Offered Stock in accordance with Section 4.1(b). Any redemption made pursuant to
this Section 4.1(d) shall be consummated by the later of: (i) sixty (60) days
after the completion of the procedures set forth in this Section 4.1 and (ii)
thirty (30) days following the date of the last of any regulatory approvals
required in connection with such action. In the event that the Board seeks an
independent third party valuation in connection with its determination of the
fair market value of the Offered Stock under this Section 4.1(d) the fees and
expenses of any such independent third party shall be shared equally by the
Selling Class B Common Stockholder and the Corporation.

       (e)    If (i) the sum of (A) the number of shares of the Offered Stock
elected to be purchased by the Acquiring Class B Common Stockholders pursuant to
Section 4.1(c) and (B) the number of shares of Offered Stock which the Board
elects to redeem pursuant to Section 4.1(d) does not equal at least fifty
percent (50%) of the Offered Stock, then the Selling Class B Common Stockholder
shall not be required to Transfer any of the Offered Stock to the Acquiring
Class B Common Stockholders or pursuant to Section 4.1(d) and all of the Offered
Stock may then be sold to the Person making the Offer and (ii) the sum of (A)
the number of shares of Offered Stock elected to be purchased by the Acquiring
Class B Common Stockholders pursuant to Section 4.1(c) and (B) the number of
shares of Offered Stock which the Board elects to redeem pursuant to Section
4.1(d) is equal to or greater than fifty percent (50%) of the Offered Stock,
then the Selling Class B Common Stockholder shall be required to Transfer such
Offered Stock to the Acquiring Class B Common Stockholders or pursuant to
Section 4.1(c), and all of the remaining Offered Stock, if any, may then be sold
to the Person making the Offer; PROVIDED, HOWEVER, that any such sale (a "SALE")
must be made on terms and conditions that are no less favorable to the Selling
Class B Common Stockholder than the terms and conditions set forth in the Notice
and to the Person or Persons described in the Offer and Offer Notice, and any
proposed sale to a different Person or Persons or upon more favorable terms and
conditions to the offeror shall be voidable by the Corporation, which may refuse
to transfer such Offered Stock upon its books. If any Sale made pursuant to the
Offer is not consummated within the later of: (A) sixty (60) days after
completion of the procedures set forth in this Section 4.1 and (B) thirty (30)
days following the date of the last of any regulatory approvals required in
connection with such Sale, the Securities covered by the Offer shall again
become subject to the restrictions of this Section 4 as though no Offer had ever
been made.

       4.2    CONDITIONS OF TRANSFER. No Transfer subject to this Section 4,
even if otherwise permitted by the terms of this Section 4, may be effected
unless (i) such Transfer will not result in (A) a violation of the Securities
Act or any rules and regulations thereunder, or (B) a violation of any
investment representation given by the transferor, (ii) prior to the
effectiveness of such Transfer, the

                                       23
<Page>

transferor at its expense shall have delivered to the Corporation, if so
requested by the Corporation, an opinion of counsel in form and substance
reasonably satisfactory to the Corporation, that the foregoing conditions set
forth in clause (i) are satisfied, and (iii) the transferee executes such other
instruments, agreements and other documents as a majority of the entire Board
(without regard to vacancies) may reasonably deem necessary to effect the
purposes of this Agreement.

       4.3    RESTRICTIONS ON TRANSFER. Upon a Qualified Transfer, the
transferee to whom such shares of Class B Common Stock are Transferred or
assigned shall be subject to all of the terms and conditions of this Agreement,
and no Transfer pursuant to a Qualified Transfer or assignment of any shares of
Class B Common Stock of the Corporation by any Class B Common Stockholder may be
effected unless the transferee or assignee assumes in writing all of the terms
and conditions of this Agreement, upon which assumption such transferee shall be
deemed a Class B Common Stockholder for all purposes of this Agreement,
including, without limitation, Section 3 hereof.

SECTION 5.    SUBSCRIPTION RIGHTS.

       (a)    Except as expressly provided in this Agreement, no holder of any
class or series of capital stock of the Corporation shall be entitled to, and
the Corporation shall not grant to any holder of any class or series of capital
stock of the Corporation pre-emptive or similar rights to subscribe for,
purchase or receive any part of any new or additional issue of Securities,
whether now or hereafter authorized; PROVIDED, HOWEVER, that the Corporation may
grant such rights provided they are subordinate in all respects to those of the
Class B Common Stockholders under this Section 5.

       (b)    In the event the Corporation desires to sell or issue shares of
its Securities (directly or indirectly), in an offering (other than an
underwritten public offering) to any Class B Common Stockholder or its
Affiliates or to any holder of Securities of the Corporation issued prior to a
Qualified IPO (other than employees or consultants pursuant to a stock purchase
and stock option plans approved by two-thirds of the Board as provided in the
Bylaws (each a "PERMITTED ISSUANCE")), the Corporation shall be required to
first submit written notice to the Class B Common Stockholders identifying the
terms of the proposed sale (including price, number or aggregate principal
amount of Securities and all other material terms), and offer to each Class B
Common Stockholder the opportunity to purchase its Pro Rata Allotment on terms
and conditions, including price, not less favorable than those on which the
Corporation proposes to sell such Securities to a third party or parties. The
Corporation's offer to the Class B Common Stockholders shall remain open and
irrevocable for a period of thirty (30) days during which time each Class B
Common Stockholder may accept such offer by written notice to the Corporation
setting forth the maximum number of shares or Securities to be purchased by any
such holder. If not all of the Class B Common Stockholders elect to purchase
their full Pro Rata Allotment of Securities, then the Corporation shall notify
in writing the participating Class B Common Stockholders of such and shall offer
such Class B Common Stockholders the right to acquire such unsubscribed
Securities. Each participating Class B Common Stockholder so notified shall have
the right to purchase up to its pro rata share of the unsubscribed Securities
(based on such holder's relative Subscription Portion to the Subscription
Portion of each of the other participating Class B Common Stockholders) within
thirty (30) days from the date of such notice from the Corporation by giving
written notice to the Corporation and stating therein the quantity of
unsubscribed Securities to be purchased. Following such thirtieth (30th) day,
but no earlier than the consummation of the issuance of shares to the other
Class B

                                       24
<Page>

Common Stockholders pursuant to this Section 5(b) and within sixty (60) days
following such thirtieth (30th) day, the Corporation may issue all of the
Securities proposed to be offered. Notwithstanding the foregoing, the right to
purchase shall be inapplicable with respect to any Permitted Issuance.

       (c)    For purposes of Section 5(b), a Class B Common Stockholder's "PRO
RATA ALLOTMENT" shall mean a proportion of the Securities of the type being
issued equal to such Class B Common Stockholder's Subscription Portion
multiplied by the amount of Securities being issued. For the avoidance of doubt,
the Securities issued to a Class B Common Stockholder upon exercise of such
Class B Common Stockholder's rights pursuant to Section 5(b) hereof shall be in
addition to and shall not reduce the amount of Securities being sold by the
Corporation to third parties. "SUBSCRIPTION PORTION" shall mean a ratio equal to
such Class B Common Stockholder's Deemed Ownership divided by the Corporate
Capitalization, calculated as of five (5) Business Days prior to the date of the
Corporation's written offer to the holders of Class B Common Stock pursuant to
Section 5(b).

SECTION 6.    IRREVOCABLE PROXY. Each Class B Common Stockholder hereby
irrevocably grants to and appoints the Corporation, and each of its officers, as
such Class B Common Stockholder's proxy and attorney-in-fact pursuant to and in
accordance with the requisite provisions of the Delaware General Corporation Law
("DGCL"), with full power of substitution to vote all of such Class B Common
Stockholder's Voting Securities on any matter described in Sections 2(a) through
2(f) hereof at any meeting of the Corporation's stockholders (whether annual or
special and whether or not an adjourned or postponed meeting) or, with respect
to any action by written consent in lieu of a meeting of the Corporation's
stockholders involving any matter described in Sections 2(a) through 2(f)
hereof, by executing the written consent (or any other documents or instrument
related thereto) with respect to all Voting Securities of such Class B Common
Stockholder and delivering the same to the Corporation in the manner required by
the requisite provisions of the DGCL. THIS PROXY AND POWER OF ATTORNEY ARE
IRREVOCABLE AND ARE COUPLED WITH AN INTEREST AND, TO THE EXTENT PERMITTED UNDER
APPLICABLE LAW, SHALL BE VALID AND BINDING ON ANY PERSON TO WHOM A CLASS B
COMMON STOCKHOLDER MAY TRANSFER ANY OF SUCH CLASS B COMMON STOCKHOLDER'S VOTING
SECURITIES IN BREACH OF THIS AGREEMENT. Each Class B Common Stockholder hereby
revokes all other proxies and powers of attorney given with respect to the
foregoing matters that may have heretofore been appointed or granted, and no
subsequent proxy or power of attorney shall be given or written consent executed
(and if given or executed, shall not be effective) by any Class B Common
Stockholder with respect thereto. All authority herein conferred or agreed to be
conferred shall survive the death or incapacity of any Class B Common
Stockholder, and the termination of the irrevocable proxy and any obligation of
each Class B Common Stockholder under this Agreement shall be binding upon the
heirs, personal representatives, successors and assigns of such Class B Common
Stockholder. Each Class B Common Stockholder represents that any proxies
heretofore given with respect to the foregoing matters are not irrevocable, and
that any such proxies are hereby revoked; PROVIDED, HOWEVER, that this proxy
does not apply to any stockholder vote other than the votes set forth in Section
2 hereof.

                                       25

SECTION 7.    RESTRICTIONS ON RELATIONSHIPS WITH PROHIBITED ENTITIES.

       (a)    Notwithstanding the provisions in Article XIII of the Certificate
of Incorporation, for a period ending two (2) years after the date of this
Agreement, so long as any Class B Common Stockholder holds a majority of the
shares of any series of Class B Common Stock which then has a right to elect a
Class B Director pursuant to Section 7.1(a) of the Certificate of Incorporation,
neither such Class B Common Stockholder nor any of its Affiliates (other than
the Corporation, the Operating Company, or any Controlled Affiliate of either of
them) shall (A) hold or acquire Beneficial Ownership of any Securities in any
Prohibited Entity or a contractual right to receive Securities of any such
Prohibited Entities, or (B) contract to provide such Prohibited Entities with
any technology (by license or otherwise), any services, including, without
limitation, promotional or marketing services, periodic exclusive promotions, or
published fare and inventory information, in each case in exchange for either
Securities of such the Prohibited Entities or a contractual right to receive
Securities of such Prohibited Entities on specific terms and conditions.
Notwithstanding anything to the contrary contained in this Section 7(a), no
Class B Common Stockholder or any of its Affiliates shall be in any way
prohibited from (X) participating as a vendor or otherwise on web sites operated
by any Person (including the Prohibited Entities), (Y) providing published fare
and inventory information to any travel agency or Global Distribution System, or
(Z) consummating any transaction or series of related transactions involving a
merger, acquisition, liquidation, dissolution, recapitalization, consolidation,
reorganization, sale, share exchange, tender or exchange offer, or other form of
business combination with a Person if following such transaction or
transactions, the continuing, successor, resultant or surviving Person holds or
has Beneficial Ownership of less than five percent (5%) of the Securities in any
of the Prohibited Entities. No Class B Common Stockholder shall be deemed to
have breached the foregoing provisions of this Section 7(a) by the acquisition
of Securities or the right to receive Securities in any of the Prohibited
Entities so long as such holder ensures that such Securities are disposed of
within thirty (30) days of the date an executive officer of such Class B Common
Stockholder obtains knowledge that such Securities or the right to receive
Securities have been acquired.

       (b)    Notwithstanding the provisions in Article XIII of the Certificate
of Incorporation, for a period ending two (2) years after the date of this
Agreement, each Class B Common Stockholder shall not, and shall cause its
Affiliates (other than the Corporation, the Operating Company or any Controlled
Affiliate of either of them) not to, act in concert with two or more other Class
B Common Stockholders or such other Class B Common Stockholder's Affiliates in
holding or acquiring Beneficial Ownership of more than ten percent (10%) amongst
such Persons in the aggregate of the Securities of any Person (other than the
Corporation or its Controlled Affiliates) that, directly or indirectly through
one or more of its Affiliates, offers the direct sale to consumers of air travel
products and services predominantly through the Internet (an "AIR TRAVEL SITE").
Notwithstanding anything to the contrary contained in this Section 7(b), no
Class B Common Stockholder or any of its Affiliates shall be in any way
prohibited from (V) participating as a vendor or otherwise on web sites operated
by any Person, (W) providing fare, inventory and other airline information to
any travel agency or Global Distribution System, (X) owning, operating or
supporting its own Airline Internet Site or an Alliance Partner Site (as defined
in the Charter Associate Agreement between the Corporation and such Class B
Common Stockholder (or an Affiliate of such holder)), (Y) maintaining any
investment existing on the date hereof in any Securities of any Person (which
existing investment shall be deemed to include any current or additional
investment in Priceline) or

                                       26
<Page>

any investment that represents a continuation of such existing investment in any
Securities of any corporate or non-corporate successor of such Person whether by
virtue of a merger, acquisition, consolidation, reorganization, sale or other
business combination or other type of transaction or series of related
transactions, or (Z) obtaining Beneficial Ownership of Securities of an Air
Travel Site in exchange for a contribution of inventory to, or participation in,
such Air Travel Site, PROVIDED that the fair market value of such Securities as
determined on the date of receipt of such Securities is less than ten million
dollars in the aggregate. No Class B Common Stockholder shall be deemed to have
breached the foregoing provisions of this Section 7(b) by the acquisition of
Securities or the right to receive Securities in any Air Travel Site so long as
such holder ensures that such Securities are disposed of within thirty (30) days
of the date an executive officer of such Class B Common Stockholder obtains
knowledge that such Securities or the right to receive such Securities have been
acquired. Notwithstanding anything herein to the contrary, the limitations in
this Section 7(b) shall terminate if there exists an intentional and systematic
breach by the Corporation of any of its obligations to any Class B Common
Stockholder under (i) this Agreement or (ii) any commercial agreement whereby
such Class B Common Stockholder has agreed to provide the Corporation with fare,
inventory and other airline information for air transportation for inclusion and
sale on the Corporation's Internet site, in each case, if such breach is not
cured within forty-five (45) days following written notice by the applicable
Class B Common Stockholder to the Corporation, identifying such breach, and
following such 45th day (but in no event more than thirty (30) days after such
45th day), the Class B Common Stockholders determine (acting with the approval
of the holders of a majority of the Voting Power of Class B Common Stock) to
exercise this right of termination. For purposes of this Section 7(b), "cured"
shall mean the discontinuation by the Corporation of the actions or practice
resulting in the noticed breach of its obligations within forty-five (45) days
of notice thereof, and shall not require remedy of the historic breach. For the
avoidance of doubt, the foregoing sentence shall not be deemed to alter, amend,
repeal or waive any rights or remedies such Class B Common Stockholder may be
entitled to under such commercial agreement.

       (c)    Notwithstanding anything to the contrary contained in Sections
7(a) or 7(b), the restrictions and limitations described in Sections 7(a) and
7(b) shall not apply to any Securities or any contractual right to receive
Securities of any Person (including the Prohibited Entities) that are acquired
or held by any Class B Common Stockholder or any Affiliate of any Class B Common
Stockholder in its capacity as the trustee, manager or investment advisor for
any pension fund, mutual fund, private equity or separate investment account
sponsored by or for the benefit of any Person including a Class B Common
Stockholder or any of its Affiliates, provided that any such Securities or any
contractual rights to receive any such Securities were not in exchange for an
executory agreement with any Class B Common Stockholder or any of its Affiliates
to provide such Person with fare, inventory and other airline information for
air transportation for sale by such Person.

SECTION 8.    AGREEMENT TO CONTINUE COMMERCIAL RELATIONSHIP. For the period
ending two (2) years after the date of this Agreement, each Class B Common
Stockholder shall, and shall cause its Affiliates which are party thereto, to
either (i) continue to be a party to and perform its and/or their obligations
under, the Charter Associate Agreement with the Corporation or its Subsidiaries
or (ii) be a party to a commercial agreement with the Corporation or any of its

commercial agreement for the provision of published fare and inventory
information for air transportation between such Class B Common Stockholder
and the Corporation or such Subsidiary (the "PRIOR COMMERCIAL AGREEMENT");
PROVIDED, that such cure notice in this section (y) shall not be effective

Commercial Agreement already executed by the Corporation or such Subsidiary,
such Class B Common Stockholder does not execute and deliver such signature
page to the Corporation or such Subsidiary within ten (10) days of such
receipt from the Corporation or such Subsidiary.
